different descriptions of the plan of distribution (contained under the caption
"Underwriting" in each of the United States and International Prospectuses) and
(ii) the International Prospectus contains an additional section under the
caption "Certain U.S. Federal Tax Considerations for Non-U.S. Holders of Common
Stock". The form of United States Prospectus is included herein and is followed
by those pages to be used in the International Prospectus which differ from, or
are in addition to, those in the United States Prospectus. Each of the pages for
the International Prospectus included herein is labeled "Alternate Page for
International Prospectus". If the Registration Statement becomes effective in
accordance with Rule 430A under the Securities Act of 1933, the complete United
States Prospectus and International Prospectus in the forms in which they are to
be used will be filed with the Securities and Exchange Commission pursuant to

full-service contract research, sales and marketing services to the global
pharmaceutical, biotechnology and medical device industries. The Company,
through the use of its extensive information technology capabilities, provides a
broad range of fully-integrated contract services in order to accelerate the
time from discovery to peak market acceptance of a new therapy by offering both
traditional contract research services and contract sales and marketing
services. In addition, the Company provides health economics and healthcare
policy consulting and disease and health information management services to
support the growing information needs of the healthcare industry. Since 1992,
the Company's annual net revenue has increased from $96.3 million to $537.6
million in 1996 and during the same period its annual net income available for
common shareholders increased from $2.8 million to $32.1 million, excluding
non-recurring costs. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations". During 1996, the Company provided services
to 49 of the 50 largest pharmaceutical companies in the world as ranked by 1995
healthcare revenue and the 11 largest biotechnology companies in the world as
ranked by market capitalization in December 1996. See "Business -- Clients and
Marketing". The Company presently has over 50 offices located in 20 countries
and approximately 7,375 employees.
 
     Since its inception in 1982, the Company has continued to expand the scope
of its services and geographic presence to support the needs of its clients on a
worldwide basis. The Company has implemented a number of strategic initiatives
to broaden its array of services and create new opportunities for growth. In
November 1996, the Company completed a business combination with Innovex Limited
("Innovex"), an international contract services organization specializing in
managing the sales and marketing of drugs for pharmaceutical companies. Innovex
enables the Company to complement its clinical research focus on obtaining
regulatory approval with services designed to assist clients in achieving market
penetration of new therapies. Also in November 1996, the Company acquired BRI
International, Inc. ("BRI"), a leading international contract research firm
specializing in medical device development and regulatory compliance consulting.
In May 1996, the Company acquired the operating assets of Lewin-VHI, Inc., a
nationally-recognized healthcare consulting firm, and formed a new subsidiary of
the Company, The Lewin Group Inc. ("Lewin"). In February 1996, the Company
acquired PMC Contract Research AB ("PMC"), a contract research organization
("CRO") located in Uppsala, Sweden, which has extensive clinical trials
management expertise. During 1996, the Company added
                                        3
<PAGE>   7
 
more than 20 new offices through acquisitions and internal growth and commenced
construction of a 171,000 square foot clinical trial drug formulation,
manufacturing, packaging and distribution facility in Bathgate, Scotland.
 
     The Company has created an organizational structure that enables the
Company to fully integrate its broad range of contract services and cross-sell
them more comprehensively. The Company's contract research services include
clinical trial studies in Phases I through IIIa of drug development, clinical
data management and biostatistical analysis, laboratory services, formulation
and packaging of clinical trial drugs, pre-clinical services, regulatory affairs
and medical device consulting. The Company's services for the perimarketing
period, which the Company defines as the period from two years before to two
years after regulatory approval, include clinical trial studies in Phases IIIb
and IV, as well as pharmaceutical sales and marketing services. The Company's
healthcare consulting services include health economics and healthcare policy
consulting and disease and health information management services.
 
     The Company's focused strategy is to: (i) provide a broad array of
fully-integrated contract services; (ii) offer specialized services in key
therapeutic areas in order to facilitate an expedited drug development process;
(iii) expand its geographic presence to support the worldwide needs of the
pharmaceutical, biotechnology and medical device industries; (iv) increase its
penetration of contract sales and marketing services, particularly in the United
States and Europe, by leveraging the Company's strong contract research presence
in these markets; (v) extend its leadership position in information technology;
and (vi) capitalize on the growing importance of health economics and disease
information management services in the healthcare industry.
 
     The Company competes in the CRO industry which typically provides
independent product development services for the pharmaceutical, biotechnology
and medical device industries. Companies in these industries are increasingly
outsourcing product development services to CROs in order to manage the drug and
medical device development process more efficiently and cost-effectively and to
maximize the benefits in time and profit of patent-protected products. CROs
manage clinical trials for drugs, provide scientific evaluations and analyze the
results as required by the applicable regulatory authorities and provide similar
services for the medical device industry. The Company also competes in the
emerging contract sales industry which provides sales and marketing services on
a contract basis to the pharmaceutical industry. The contract sales industry
emerged in the 1980s, most notably in the United Kingdom (the "U.K.") where, the
Company believes, regulatory cost containment pressures on pharmaceutical
companies led such companies to outsource sales and marketing activities
relating to product launch. Contract sales organizations assemble and train a
contract sales force to help launch a pharmaceutical company's newly approved
products. The Company believes that it is the leading company to couple contract
research services with contract sales and marketing services.
 
     The Company's principal executive offices are located at 4709 Creekstone
Drive, Riverbirch Building, Suite 300, Durham, North Carolina 27560 and its
telephone number is (919) 941-2000. Unless the context otherwise requires, the
term the "Company" refers to Quintiles Transnational Corp. and its subsidiaries.

(1) Prior to the Company's November 29, 1996 share exchange with Innovex,
    Innovex had a fiscal year end of March 31, and the Company had (and
    continues to have) a fiscal year end of December 31. As a result, the pooled
    data presented above for 1992 through 1995 include Innovex's March 31 fiscal
    year data in combination with the Company's December 31 fiscal year data. In
    connection with the share exchange, Innovex changed its fiscal year end to
    December 31. Accordingly, the pooled data presented above for 1996 include
    both Innovex's and the Company's data on a December 31 year end basis.
    Because of the difference between Innovex's fiscal year end in 1995 compared
    with 1996, Innovex's quarter ended March 31, 1996 data are included in the
    Company's pooled data for both 1995 and 1996.
(2) Reimbursed costs consist primarily of payments to third party physician
    investigators, travel and other costs that are billed to and reimbursed by
    the Company's clients. See "Management's Discussion and Analysis of
    Financial Condition and Results of Operations".

                                  RISK FACTORS
 
     In addition to the other information contained or incorporated by reference
in this Prospectus, prospective purchasers should consider the following factors
carefully in evaluating the Company and its business before purchasing the
Common Stock offered hereby. See also "Forward Looking Statements".
 
DEPENDENCE ON CERTAIN INDUSTRIES AND CLIENTS
 
     The Company's revenues are highly dependent upon the research and
development and sales and marketing expenditures of the pharmaceutical and
biotechnology industries. The Company has benefited to date from the growing
tendency of pharmaceutical and biotechnology companies to engage independent
outside organizations to conduct large clinical research and sales and marketing
projects. The Company's operations could be materially and adversely affected by
a general economic decline in these industries or by any reduction in the
outsourcing of development or sales and marketing expenditures. The Company has
in the past derived, and may in the future derive, a significant portion of its
net revenue from a relatively limited number of major projects or clients. In
1996, 10 clients accounted for approximately 48% of the Company's consolidated
net revenue. As pharmaceutical companies continue to outsource large projects
and studies to fewer full-service global providers, the concentration of
business could increase. The Company is likely to experience such concentration
in 1997 and in future years. The loss of any such client could materially and
adversely affect the Company. See "Business -- Clients and Marketing".
 
MANAGEMENT OF GROWTH
 
     The Company has experienced rapid growth over the past 10 years. The
Company believes that its sustained growth places a strain on operational, human
and financial resources. In order 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 personnel.
Foreign operations may involve the additional risks of assimilating differences
in foreign business practices, hiring and retaining qualified personnel, and
overcoming language barriers. The Company has a transnational organizational
structure, comprised of three operating divisions performing complementary
functions with a holding company performing management functions. While this
transnational structure has successfully supported the Company's growth to date,
the Company recently has completed a number of acquisitions, and there can be no
assurance that this structure will continue to be effective. See "Business --
General". Failure to manage growth effectively could have a material adverse
effect on the Company.
 
ACQUISITION RISKS
 
     Acquisitions involve numerous risks, including difficulties and expenses
incurred in connection with the acquisition and the assimilation of the
operations and services of the acquired companies, the diversion of management's
attention from other business concerns and the potential loss of key employees
of the acquired companies. Acquisitions of foreign companies also may involve
the additional risks of assimilating differences in foreign business practices
and overcoming language barriers. Since February 1996, the Company has completed
four acquisitions, both within the United States and internationally. There can
be no assurance that the Company's past and any future acquisitions will be
successfully integrated into its operations. See "Business -- General". The
Company reviews many acquisition candidates in the ordinary course of business,
and the Company continually is evaluating new acquisition opportunities. Given
the CRO industry consolidation which is occurring, the Company expects to
continue to evaluate and compete for suitable acquisition candidates. There can
be no assurance that the Company will successfully complete future acquisitions
nor that acquisitions, if completed, will contribute favorably to the Company's
operations and future financial condition. Although the Company performs due
diligence investigations on each company or business it seeks to acquire, there
may be liabilities which the Company fails or is unable to discover for which
the Company, as a successor owner, may be liable. The Company generally seeks to
minimize its exposure to such liabilities by obtaining indemnification from each
seller, which may be supported by deferring payment of a portion of the
 
                                        7
<PAGE>   11
 
purchase price. However, there is no assurance that such indemnifications, even
if obtainable, enforceable and collectible (as to which there also is no
assurance), will be sufficient in amount, scope or duration to fully offset the
potential liabilities arising from the acquisitions.
 
RISKS RELATING TO CONTRACT SALES SERVICES
 
     Outsourced contract sales services is a relatively new industry outside the
U.K. The Company believes that the contract sales industry emerged in the 1980s,
primarily in the U.K., because of regulatory cost containment pressure on
pharmaceutical companies. As a result, large pharmaceutical companies began to
outsource their sales and marketing activities incident to product launch. There
is a relatively low level of market penetration for outsourced sales and
marketing services in most other countries, including the United States. As
such, companies in this industry are subject to all of the risks inherent in a
new or emerging industry, including an inability to attract and retain clients,
changes in the regulatory regime, an absence of an established earnings history,
the availability of adequately trained sales representatives and additional and
unforeseen costs and expenses. There can be no assurance that the Company will
be able to market successfully its contract sales and marketing services outside
the U.K. See "Business -- Services".
 
COMPETITION; INDUSTRY CONSOLIDATION
 
     The market for the Company's contract research services is highly
competitive, and the Company competes against traditional CROs, the in-house
research and development departments of pharmaceutical companies, as well as
universities and teaching hospitals. In sales and marketing services, the
Company competes against the in-house sales and marketing departments of
pharmaceutical companies and small local contract sales organizations in each
country in which it operates. The Company also competes against consulting firms
offering healthcare consulting services, including boutique firms specializing
in the healthcare industry and the healthcare departments of large firms.
Expansion by these competitors into other areas in which the Company operates
could affect the Company's competitive position. Increased competition may lead
to price and other forms of competition that may affect the Company's margins.
See "Business -- Competition". Consolidation within the pharmaceutical industry,
as well as a trend by pharmaceutical companies to limit outsourcing to fewer
organizations, has heightened the competition for contract research services. As
a result, consolidation also has occurred among the providers of contract
research services, and several large, full-service providers have emerged,
including the Company. If these consolidation trends continue, they may result
in greater competition among the larger contract research providers for clients
and acquisition candidates.
 
LOSS OR DELAY OF LARGE CONTRACTS; FIXED PRICE NATURE OF CONTRACTS
 
     Most of the Company's contracts are terminable upon 15-90 days' notice by
the client. Although the contracts typically provide for payment of certain fees
for winding down the study and, in some cases, a termination fee, the loss or
delay of a large contract or the loss or delay of multiple contracts could
adversely affect the Company's future net revenue and profitability. Contracts
may be terminated for a variety of reasons, including the failure of a product
to satisfy safety requirements, unexpected or undesired results of the product,
the client's decision to forego a particular study or insufficient patient
enrollment or investigator recruitment. The Company contracts with investigators
who undertake to recruit large numbers of patients in many of its studies. There
can be no assurance that the Company will always be able to satisfy recruitment
targets, particularly in large studies for which there is little precedent. In
addition, most of the Company's contracts for the provision of its services are
fixed price or fee-for-service subject to a cap. Since the Company's contracts
are predominantly structured in this manner, the Company bears the risk of cost
overruns. Underpricing of contracts or significant cost overruns could have a
material adverse effect on the Company.
 
                                        8
<PAGE>   12
 
DEPENDENCE ON PERSONNEL
 
     The Company relies on a number of key executives, including Dennis B.
Gillings, Ph.D., its Chairman of the Board of Directors and Chief Executive
Officer. The Company maintains key man life insurance on Dr. Gillings in the
amount of $3 million. The loss of the services of any key executives could have
a material adverse effect on the Company. In addition, the Company's performance
depends on its ability to attract and retain qualified management and
professional, scientific and technical operating staff, as well as its ability
to recruit qualified representatives for its contract sales services. There can
be no assurance that the Company will be able to continue to attract and retain
qualified personnel.
 
POTENTIAL LIABILITY
 
     In connection with its provision of contract research services, the Company
contracts with physicians to serve as investigators in conducting clinical
trials to test new drugs on human volunteers. Such testing creates risk of
liability for personal injury or death to volunteers, particularly to volunteers
with life-threatening illnesses, resulting from adverse reactions to the drugs
administered. 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 for the claims and expenses arising from any
professional malpractice of the investigators with whom it contracts or in the
event of personal injury 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. In addition, as a result of its Phase I clinical
trials facilities, the Company could be liable for the general risks associated
with a Phase I facility including, but not limited to, adverse events resulting
from the administration of drugs to clinical trial participants or the
professional malpractice of Phase I medical care providers. The Company believes
that its risks are reduced by contractual indemnification provisions with
clients and investigators, insurance maintained by clients and investigators and
by the Company, various regulatory requirements, including the use of
institutional review boards and the procurement of each volunteer's informed
consent to participate in the study. The contractual indemnifications generally
do not protect the Company against certain of its own actions such as
negligence. The contractual arrangements are subject to negotiation with clients
and the terms and scope of such indemnification vary from client to client and
from trial to trial. The financial performance of these indemnities is not
secured. Therefore, the Company bears the risk that the indemnifying party may
not have the financial ability to fulfill its indemnification obligations. 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 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 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 beyond the level of insurance coverage or in the event that an
indemnifying party does not fulfill its indemnification obligations.
 
DEPENDENCE ON GOVERNMENT REGULATION
 
     The Company's contract research business has benefited from the extensive
governmental regulation of the drug development process, particularly in the
United States. In Europe, the general trend has been towards establishing common
standards for clinical testing of new drugs, leading to changes in the various
requirements currently imposed by each country. The Company believes that the
level of regulation is generally less burdensome outside the United States. From
time to time legislation is introduced in the U.S. Congress to substantially
modify regulations administered by the Food and Drug Administration ("FDA")
governing the drug approval process. Changes in regulation in the United States
or elsewhere, including mandatory substitution of generic drugs for patented
drugs, relaxation in the scope of regulatory requirements or the introduction of
simplified drug approval procedures, could decrease the business opportunities
available to the Company. In addition, the failure on the part of the Company to
comply with applicable regulations could result in the termination of ongoing
clinical research
 
                                        9
<PAGE>   13
 
or sales and marketing projects or the disqualification of data for submission
to regulatory authorities, either of which could have a material adverse effect
on the Company.
 
UNCERTAINTY IN HEALTHCARE INDUSTRY AND POSSIBLE HEALTHCARE REFORM
 
     The healthcare industry is subject to changing political, economic and
regulatory influences that may affect the pharmaceutical, biotechnology and
medical device industries. Numerous governments have undertaken efforts to
control growing healthcare costs through legislation, regulation and voluntary
agreements with medical care providers and pharmaceutical companies.
Implementation of government healthcare 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. Management is unable to predict the likelihood of such legislation
being enacted into law or the effects such legislation would have on the
Company.
 
EXCHANGE RATE FLUCTUATIONS
 
     Approximately 56.5%, 59.2% and 57.0% of the Company's net revenue for the
years ended December 31, 1996, 1995, and 1994, respectively, were derived from
the Company's operations outside the United States. The Company's operations and
financial results could be significantly affected by factors associated with
international operations such as changes in foreign currency exchange rates and
uncertainties relative to regional economic circumstances, as well as by other
risks sometimes associated with international operations. Since the revenue and
expenses of the Company's foreign operations are generally denominated in local
currencies, exchange rate fluctuations between such local currencies and the
U.S. dollar will subject the Company to currency translation risk with respect
to the reported results of its foreign operations. Also, the Company may be
subject to foreign currency transaction risks when the Company's service
contracts are denominated in a currency other than the currency in which the
Company incurs expenses related to such contracts. The Company limits its
foreign currency transaction risks through exchange rate collars stated in its
contracts with clients or the Company hedges the transaction risk with foreign
exchange contracts or options. There can be no assurance that the Company will
not experience fluctuations in financial results from the Company's operations
outside the United States, and there can be no assurance the Company will be
able to contractually or otherwise favorably reduce its currency transaction
risk associated with its service contracts. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations".
 
VARIATION IN QUARTERLY OPERATING RESULTS
 
     The Company's results of operations have been and can be expected to be
subject to quarterly fluctuations. Quarterly results can fluctuate as a result
of a number of factors, including the timing of start-up expenses for new
offices, acquisitions, the completion or commencement of significant contracts,
changes in the mix of services offered and foreign exchange fluctuations. 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".
 
VOLATILITY OF STOCK PRICE
 
     The market price of the Company's Common Stock has been and may continue to
be subject to wide fluctuations in response to variations in operating results
from quarter to quarter, changes in earnings estimates by analysts, market
conditions in the industry and general economic conditions. See "Price Range of
Common Stock and Dividend Policy".

<PAGE>   14
 
                                USE OF PROCEEDS
 
     The Company intends to use the net proceeds from the sale of the shares of
Common Stock offered by the Company in the United States offering (the "U.S.
Offering") and the concurrent international offering (the "International
Offering" and, together with the U.S. Offering, the "Offerings") for the
replenishment of working capital following the Company's repayment in November
1996 of approximately $56.8 million of obligations assumed in the share exchange
with Innovex. The Company intends to use this working capital and the remaining
proceeds from the Offerings for geographic expansion, addition of new services,
potential acquisitions, general corporate purposes and capital expenditures,
including approximately $23.4 million to complete construction of the Company's
171,000 square foot clinical trial drug formulation, manufacturing, packaging
and distribution facility in Bathgate, Scotland. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and "Business".
Pending such uses, the Company intends to invest the net proceeds from the
Offerings in investment grade, interest-bearing securities. The Company will not
receive any of the proceeds from the sale of Common Stock by the Selling
Shareholders in the Offerings.
 
     As part of its business strategy, the Company reviews many acquisition
candidates in the ordinary course of business, and the Company continually is
evaluating new acquisition opportunities. There is no assurance that the Company
will complete other acquisitions. No binding agreements or firm commitments
currently exist to make any material acquisition, and no portion of the net
proceeds has been allocated for any specific material acquisition. See "Risk
Factors -- Acquisition Risks".
 
                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
     The Company's Common Stock has traded publicly on the Nasdaq National
Market under the trading symbol "QTRN" since April 20, 1994, the date that the
Common Stock was first offered to the public. The table below sets forth the
high and low sale prices for the Company's Common Stock for the periods
indicated as reported by the Nasdaq National Market. Such prices are adjusted to
reflect the two-for-one stock split effected as a 100% stock dividend on
November 27, 1995.

     On February 5, 1997, the last sale price reported on the Nasdaq National
Market for the Common Stock was $76.00 per share. On December 31, 1996, the
Company had 33,149,962 shares of Common Stock outstanding, and there were
approximately 8,950 beneficial owners of the Common Stock.
 
     The Company has never declared or paid any cash dividends on its Common
Stock, and the Company's existing domestic credit facility prohibits the payment
of dividends without the prior consent of the lender. The Company does not
anticipate paying any cash dividends in the foreseeable future and intends to
retain future earnings for the development and expansion of its business.

(1) Prior to the Company's November 29, 1996 share exchange with Innovex,
    Innovex had a fiscal year end of March 31 and the Company had (and continues
    to have) a fiscal year end of December 31. As a result, the pooled data
    presented above for 1992 through 1995 include Innovex's March 31 fiscal year
    data in combination with the Company's December 31 fiscal year data. In
    connection with the share exchange, Innovex changed its fiscal year end to
    December 31. Accordingly, the pooled data presented above for 1996 include
    both Innovex's and the Company's data on a December 31 year end basis.
    Because of the difference between Innovex's fiscal year end in 1995 compared
    with 1996, Innovex's quarter ended March 31, 1996 data are included in the
    Company's pooled data for both 1995 and 1996.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     The Company is a leading provider of full-service contract research, sales
and marketing services to the global pharmaceutical, biotechnology and medical
device industries. Additionally, the Company supports the developing information
needs of the broader healthcare industry by providing health economics and
healthcare policy consulting and disease and health information management
services.
 
     Since its inception in 1982, the Company has followed a focused strategy of
expanding the scope of its services and geographic presence to support the
worldwide needs of its client base. During 1996, through internal expansion and
strategic acquisitions, the Company considerably broadened its array of
services, created new opportunities for growth and enhanced its management team
and scientific and technical operating staff. Specifically:
 
     - On February 15, 1996, the Company acquired PMC, a CRO located in Uppsala,
      Sweden. The Company acquired PMC for approximately 273,000 shares of the
      Company's Common Stock. Additionally, approximately $1.3 million in cash
      was paid to a dissenting shareholder. The acquisition of PMC was accounted
      for as a pooling-of-interests, and all consolidated financial data for
      periods subsequent to January 1, 1996 have been restated to include the
      results of the pooled company. The financial data of the pooled companies
      prior to January 1, 1996 were not materially different from that
      previously reported by the Company, and thus have not been restated.
 
     - On May 13, 1996, the Company acquired the operating assets of Lewin-VHI,
      Inc., a healthcare consulting firm, headquartered in Fairfax, VA, and
      formed a new subsidiary of the Company, Lewin. In connection with this
      transaction, the Company paid approximately $30.0 million in cash for the
      operating assets of Lewin and issued options to Lewin's management team
      and key staff to purchase 207,157 shares of the Company's Common Stock.
 
     - In August 1996, the Company began construction of a new 171,000 square
      foot facility in Bathgate, Scotland, for formulation, manufacturing,
      packaging and distribution of clinical trial drugs. The Bathgate facility,
      currently estimated to be completed in late 1997, is anticipated to house
      300 employees and will also include a data management center.
 
     - On November 22, 1996, the Company acquired BRI, a leading international
      contract research firm, headquartered in Arlington, VA, specializing in
      medical device development and regulatory compliance consulting. The
      Company exchanged 1,614,862 shares of its Common Stock for all of BRI's
      outstanding shares of capital stock and exchanged options exercisable for
      338,693 shares of the Company's Common Stock. The Company recognized in
      the fourth quarter of 1996 approximately $2.5 million in non-recurring
      transaction costs and approximately $2.3 million in non-recurring
      restructuring costs related to the transaction. The acquisition was
      accounted for as a pooling-of-interests, and accordingly, the Company has
      restated all historical financial data to include the historical financial
      data of BRI.
 
     - On November 29, 1996, the Company effected a share exchange with Innovex,
      an international contract services organization headquartered in Marlow,
      U.K., specializing in the sales and marketing of drugs for the
      pharmaceutical industry. In the Innovex transaction, which was accounted
      for as a pooling-of-interests, the Company acquired 100% of the
      outstanding shares of Innovex in exchange for 9,214,239 shares of the
      Company's Common Stock and issued 786,226 options to purchase shares of
      the Company's Common Stock in exchange for Innovex stock options.
      Subsequently, the Company retired approximately $56.8 million of Innovex
      obligations. In the fourth quarter of 1996, related to the Innovex
      transaction, the Company recognized approximately $14.5 million in
      non-recurring transaction costs and approximately $8.5 million in non-
      recurring restructuring costs. In addition, Innovex had previously
      recognized approximately $2.4 million and $2.3 million, respectively, in
      non-recurring restructuring and special pension costs in
 
                                       15
<PAGE>   19
 
      the quarter ended March 31, 1996. The Company has restated all historical
      financial data to include Innovex historical financial data in accordance
      with pooling-of-interests accounting.
 
     For additional information regarding the transactions and financial
performance discussed and analyzed above, see "Business -- General",
"Incorporation of Certain Documents by Reference" and "Notes to Consolidated
Financial Statements" found elsewhere in this Prospectus.
 
     During the 12 months ended December 31, 1996, the Company added more than
20 offices through its acquisitions and internal growth, expanded its presence
from 16 to 20 countries, and grew from approximately 2,025 employees to
approximately 7,375 employees worldwide. To facilitate the integration of its
acquisitions, capitalize on the synergies each acquisition provides and manage
its internal growth, the Company recently reorganized into three operating
divisions which work closely together to provide the Company's services on an
integrated basis. The Contract Research Division includes clinical trial
studies, clinical data management and biostatistical analysis, laboratory
services, formulation and packaging of clinical trial drugs, pre-clinical
services, regulatory affairs and medical device consulting services. The Innovex
Division includes perimarketing clinical trial studies in Phases IIIb and IV, as
well as the Company's pharmaceutical sales and marketing services. The
Lewin-Benefit Division encompasses the Company's health economics and healthcare
policy consulting and disease and health information management services.
 
CONTRACT REVENUE
 
     Most of the Company's contracts are fixed price, with some variable
components, and range in duration from a few months to several years. Generally,
a portion of the contract fee is paid at the time the project is initiated with
performance-based installments payable over the contract duration. Most
contracts are terminable upon 15-90 days' notice by the client, and typically
provide for termination or winding down fees. Also, some client contracts call
for the client to reimburse the Company at cost for certain items such as
investigator payments and travel. These reimbursed costs are deducted from
professional fee income in calculating net revenue. The Company recognizes net
revenue from its contracts on a percentage-of-completion or per diem basis as
work is performed. Consistent with prior years' practice, the Company considers
net revenue its primary measure of revenue growth.

YEAR ENDED DECEMBER 31, 1996 COMPARED WITH YEAR ENDED DECEMBER 31, 1995
 
     Prior to the Company's November 29, 1996 share exchange with Innovex,
Innovex had a fiscal year end of March 31, and the Company had (and continues to
have) a fiscal year end of December 31. As a result, the pooled data presented
for 1992 through 1995 include Innovex's March 31 fiscal year data in combination
with the Company's December 31 fiscal year data. In connection with the share
exchange, Innovex changed its fiscal year end to December 31. Accordingly, the
pooled data presented for 1996 include both Innovex's and the Company's data on
a December 31 year end basis. Because of the difference between Innovex's fiscal
year end in 1995 compared with 1996, Innovex's quarter ended March 31, 1996 data
are included in the Company's pooled data for both 1995 and 1996.
 
     Net revenue for the year ended December 31, 1996 was $537.6 million, an
increase of $213.9 million or 66.1% over fiscal 1995 net revenue of $323.7
million. In general, growth occurred across each of the Company's three
geographic regions and within each contract service sector. Factors contributing
to both the regional and service growth include the provision of increased
services rendered under existing contracts, the initiation of services under
contracts awarded subsequent to January 1, 1996 and the Company's acquisitions
(excluding BRI and Innovex) completed during 1996 and 1995 which contributed
approximately $44.8 million in 1996 versus $11.7 million in 1995. Without these
acquisitions, the Company's 1996 net revenue increased by $180.8 million or
57.9% over comparable 1995 net revenue. As a result of the Company's broad range
of contract service offerings, one client accounted for 11.9% of the Company's
1996 net revenue. See "Business -- Clients and Marketing".
 
     Direct costs, which include compensation and related fringe benefits for
billable employees and any other expenses directly related to contracts which
are not included as reimbursed costs, were $272.6 million or 50.7% of 1996 net
revenue versus $165.3 million or 51.1% of 1995 net revenue. The decrease in
direct costs as a percentage of net revenue is primarily attributable to
efficiency realized through the use of information technology in the Company's
provision of services related to global, long-term contracts, offset by
increased costs attributable to the increase in net revenue generated from
contract sales and marketing services, which incur a higher level of direct
costs (but lower general and administrative expenses) relative to net revenue
than contract research services.
 
     General and administrative expense, which includes compensation and fringe
benefits for administrative employees, non-billable travel, professional
services, advertising, computer and facility expenses, was $187.6 million or
34.9% of 1996 net revenue versus $113.2 million or 35.0% of 1995 net revenue.
The $74.3 million growth in general and administrative expense is primarily due
to an increase in personnel, facilities and locations, business development and
marketing activities, and outside services brought on by the Company's growth.
 
     Depreciation and amortization was $24.8 million or 4.6% of 1996 net revenue
versus $16.9 million or 5.2% of 1995 net revenue.
 
     Income from operations was $37.2 million or 6.9% of 1996 net revenue versus
$23.5 million or 7.3% of 1995 net revenue. Net of non-recurring costs, income
from operations was $52.6 million or 9.8% of 1996 net revenue versus $28.2
million or 8.7% of 1995 net revenue. During the quarter ended March 31,
 
                                       18
<PAGE>   22
 
1996, Innovex recognized two non-recurring charges: a $2.4 million expense for
an Innovex internal reorganization and a related $2.3 million special pension
contribution. Accordingly, the Company's pooled, consolidated financial results
include such charges, totalling $4.7 million, in both the fiscal years ended
December 31, 1996 and 1995. In the fourth quarter of 1996, the Company
recognized approximately $10.7 million in non-recurring restructuring costs
related to the BRI and Innovex transactions.
 
     Other expense increased to $20.1 million in 1996 from $1.4 million in 1995.
Other expense includes approximately $17.1 million of non-recurring acquisition
transaction costs for the year ended December 31, 1996, most of which were not
deductible for tax purposes. Net of such non-recurring transaction costs, other
expense was $3.0 million for 1996 and $1.4 million in 1995. This increase of
approximately $1.5 million was primarily due to an increase of interest and
miscellaneous expense of $5.9 million which was offset by an increase in
interest income of approximately $4.4 million.
 
     The effective tax rate for 1996 was 69.6% versus a 37.0% rate in 1995. The
increase in the 1996 effective tax rate was primarily attributable to the
non-tax deductible, non-recurring acquisition transaction costs incurred and a
portion of the non-recurring costs relating to the Innovex restructuring prior
to its pooling-of-interests with the Company. The lack of tax relief for the
Innovex restructuring is reflected in both the effective tax rates for 1996 and
1995. The effective tax rate for 1996 was 33.6% versus a 34.7% rate in 1995
excluding the non-recurring costs. The Company's effective tax rate may vary as
profits in locations with different tax rates change. See "-- Taxes".
 
YEAR ENDED DECEMBER 31, 1995 COMPARED WITH YEAR ENDED DECEMBER 31, 1994
 
     Net revenue for 1995 was $323.7 million versus $195.9 million in 1994, an
increase of $127.8 million or 65.2%. In general, the growth occurred across each
of the Company's three geographic regions. The growth can be attributed
primarily to the increase in services rendered under existing contracts and the
initiation of services under new contract work awarded in 1995. Excluding fiscal
1995 acquisitions, which contributed net revenue of approximately $11.7 million
in that year, the Company's net revenue was $312.0 million, which represented
growth of $116.2 million or 59.3% over 1994.
 
     Direct costs, which include compensation and related fringe benefits for
billable employees and any other expenses directly related to contracts which
are not included as reimbursed costs, were $165.3 million or 51.1% of 1995 net
revenue versus $97.3 million or 49.7% of 1994 net revenue. The increase in
direct costs as a percentage of net revenue is due primarily to costs
attributable to the increasing net revenue from sales and marketing services,
which incur a higher level of direct costs (but lower general and administrative
expenses) relative to revenue than contract research services, the establishment
of start-up operations and direct costs associated with the operational
integration of the Company's acquisitions in 1995.
 
     General and administrative expense, which includes compensation and fringe
benefits for administrative employees, non-billable travel, professional
services, advertising, computer and facility expenses, was $113.2 million or
35.0% of 1995 net revenue versus $73.4 million or 37.5% of 1994 net revenue. The
$39.8 million growth in general and administrative expense is primarily due to
an increase in personnel, facilities and locations, business development and
marketing activities, information technology investments and the use of outside
services brought on by the Company's growth and operation as a publicly-held
company.
 
     Depreciation and amortization was $16.9 million or 5.2% of 1995 net revenue
versus $10.4 million or 5.3% of 1994 net revenue.
 
     Income from operations was $23.5 million or 7.3% of net revenue in 1995
versus $14.8 million or 7.6% of net revenue in 1994. The decrease as a
percentage of net revenue was due to the recognition of two non-recurring
charges: Innovex recorded a $2.4 million expense related to an internal
restructuring and a $2.3 million expense related to a special pension
contribution. Excluding these costs, income from operations would have been
approximately $28.2 million or 8.7% of 1995 net revenue.
 
                                       19
<PAGE>   23
 
     Other expense increased to $1.4 million in 1995 from $1.2 million in 1994.
Net of a 1994 one-time gain of approximately $460,000, other expense decreased
approximately $210,000. This decrease is primarily attributable to an increase
in interest income and other income of approximately $1.7 million, offset by an
increase in interest expense of $970,000 and $475,000 in non-recurring
acquisition transaction costs expensed by the Company in 1995, most of which
were not tax-deductible.
 
     The effective tax rate for 1995 was 37.0% versus a 33.6% rate in 1994. The
increase in the 1995 effective tax rate was primarily attributable to the
non-tax deductible nature of some of the non-recurring costs relating to the
internal restructuring, some of the foreign operating losses and some of the
acquisition transaction costs incurred. The Company's effective tax rate may
vary as profits in locations with different tax rates change. See "-- Taxes".

(1) Prior to the Company's November 29, 1996 share exchange with Innovex,
    Innovex had a fiscal year end of March 31, and the Company had (and
    continues to have) a fiscal year end of December 31. As a result, the pooled
    data presented above for 1992 through 1995 include Innovex's March 31 fiscal
    year data in combination with the Company's December 31 fiscal year data. In
    connection with the share exchange, Innovex changed its fiscal year end to
    December 31. Accordingly, the pooled data presented above for 1996 include
    both Innovex's and the Company's data on a December 31
 
                                       20
<PAGE>   24
 
    year end basis. Because of the difference between Innovex's fiscal year end
    in 1995 compared with 1996, Innovex's quarter ended March 31, 1996 data are
    included in the Company's pooled data for both 1995 and 1996.
(2) During the quarter ended March 31, 1996, the Company incurred non-recurring
    restructuring costs and special pension contribution in the aggregate amount
    of $4.7 million. Including such non-recurring costs, income from operations
    for the quarter ended March 31, 1996 was $7 million and net income available
    for common shareholders was $4.4 million.
(3) During the quarter ended December 31, 1996, the Company incurred
    non-recurring restructuring costs of $10.7 million and acquisition
    transaction costs of $17.1 million. Including such non-recurring costs,
    income from operations for the quarter ended December 31, 1996 was $5.3
    million and net income (loss) available for common shareholders was ($14.8
    million).
 
     Although the Company's net revenue has increased on a quarterly basis since
the beginning of 1995, income from operations and net income available for
common shareholders, as a percentage of net revenue, have fluctuated on a
quarterly basis and can be expected to continue to be subject to quarterly
fluctuations. Quarterly results can fluctuate as a result of a number of
factors, including the timing of startup expenses for new offices, the maturity
of the Company's offices, acquisitions, the completion or commencement of
significant contracts, mix of services and foreign exchange fluctuations.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Cash flows generated from operations were $28.3 million in 1996 versus
$34.5 million and $14.8 million in 1995 and 1994, respectively. Investing
activities in 1996 were $142.6 million, versus $38.1 million and $14.3 million
in 1995 and 1994, respectively. The change in the amount of cash used in
investing activities is primarily due to the investment of the Company's net
proceeds from the May 1996 private placement of its 4.25% Convertible
Subordinated Notes due May 31, 2000 and its October 1995 equity offering. Such
proceeds were used as follows: $62.7 million was invested in investment-grade,
interest-bearing securities with maturities of greater than 90 days; $11.4
million was used for the payment of non-recurring transaction costs in
connection with business combinations; $33.4 million was used for acquisitions;
and $56.8 million was used to retire Innovex obligations assumed in the share
exchange with Innovex. Approximately $45.2 million of the Innovex obligations
was related to debt incurred for the recapitalization of Innovex in April 1996.
Capital asset purchases required $39.1 million in 1996 versus $25.7 million and
$16.1 million in 1995 and 1994, respectively. Capital asset expenditures in 1996
included approximately $5.0 million related to the Company's purchase of land
and commencement of construction of a facility in Bathgate, Scotland. The
remaining capital expenditures were predominantly incurred in connection with
the expansion of existing operations, the enhancement of information technology
capabilities and the opening of new offices.
 
     Total working capital was $96.0 million at December 31, 1996 compared to
$70.0 million at December 31, 1995. Total accounts receivable and unbilled
services increased 69.9% to $178.6 million at December 31, 1996 from $105.1
million at December 31, 1995, as a result of the growth in net revenue. The
number of days revenue outstanding in accounts receivable and unbilled services,
net of unearned income was 48 days at December 31, 1996 and December 31, 1995.
 
     In August 1996, the Company began construction of a 171,000 square foot
facility in Bathgate, Scotland, expected to be completed in late 1997.
Management's current best estimate of the total capital required for the
Bathgate facility is L17.5 million (approximately $28.4 million), which includes
the acquisition of land, construction of the facility and purchase of machinery
and equipment. As of December 31, 1996, the Company had spent approximately L3.0
million (approximately $5.0 million) relating to the acquisition of land and
construction of the Bathgate facility.
 
     In November 1996, in conjunction with the Company's share exchange with
Innovex, the Company assumed the following commitments:
 
      - During 1993, Innovex acquired Clinical Research Foundation, an
        international contract research organization, for total consideration of
        approximately 32.2 DM million, of which a final payment of
 
                                       21
<PAGE>   25
 
        approximately 6.6 DM million (approximately $4.0 million) is due from
        the Company in April 1997.
 
      - In August 1996, Innovex acquired Eminent, a Spanish contract sales and
        marketing services firm. An initial payment of 100 Pesetas million was
        made in August 1996. A remaining amount of up to 700 Pesetas million
        (approximately $5.0 million) would be due over the next three years if
        certain performance measures are met.
 
     During 1995, the Company acquired a drug development facility in Edinburgh,
Scotland. Related to this acquisition, the Company entered into a purchase
commitment valued at L13.0 million (approximately $21.8 million) with payment
due in December 1999. The Company has hedged this commitment by purchasing
forward contracts. The Company's forward contracts mature on December 29, 1999,
and as of December 31, 1996, the Company had committed to purchasing
approximately L600,000 (approximately $852,000) under such contracts.
 
     The Company has renewed its previously expired $15.0 million unsecured line
of credit with a U.S. bank. Also, the Company has a $4.0 million secured line of
credit with a second U.S. bank. Additionally, the Company has available to it a
L6.0 million unsecured line of credit with a U.K. bank and a L5.0 million
secured overdraft facility with a second U.K. bank. At December 31, 1996, the
Company had $19.0 million and L5.7 million available under these credit
agreements.
 
     All foreign currency denominated amounts due, subsequent to December 31,
1996, have been translated using the Wednesday, January 29, 1997 foreign
exchange rate as published in the January 30, 1997 edition of the Wall Street
Journal.
 
     The Company's primary cash needs on both a short-term and long-term basis
are for working capital, geographic expansion, addition of new services,
potential acquisitions, general corporate purposes and capital expenditures. To
further the Company's strategy of providing a continuum of contract services
across key therapeutic categories for the rapid and cost effective development
and marketing of products for the pharmaceutical, biotechnology and medical
device industries, the Company intends to use the net proceeds of the Offerings
as described under "Use of Proceeds".
 
     Based on its current operating plan, the Company believes that its
available cash and cash equivalents, together with cash flow from operations,
borrowings under its line of credit agreements and net proceeds from the
Offerings will be sufficient to meet its foreseeable cash needs.
 
FOREIGN CURRENCY
 
     Approximately 56.5%, 59.2% and 57.0% of the Company's net revenue for the
years ended December 31, 1996, 1995, and 1994, respectively, were derived from
the Company's operations outside the United States. The Company's consolidated
financial statements are denominated in U.S. dollars, and accordingly, changes
in the exchange rate between foreign currencies and the U.S. dollar will affect
the translation of such subsidiaries' financial results into U.S. dollars for
purposes of reporting the Company's consolidated financial results.
 
     The Company may be subject to foreign currency transaction risks when the
Company's service contracts are denominated in a currency other than the
currency in which the Company incurs expenses related to such contracts. The
Company limits its foreign currency transaction risks through exchange rate
collars stated in its contracts with clients or the Company hedges the
transaction risk with foreign exchange contracts or options. The Company
recognizes changes in value in income only when contracts are settled or options
exercised. There were no open foreign exchange contracts or options relating to
service contracts at December 31, 1996.
 
TAXES
 
     Since the Company conducts operations on a global basis, the Company's
effective tax rate has and will depend on the amount of profits in locations
with varying tax rates. The Company's results of
 
                                       22
<PAGE>   26
 
operations will be impacted by changes in the tax rates of the various
jurisdictions and by changes in any applicable tax treaties. In particular, as a
portion of the Company's non-U.S. business increases, the Company's effective
tax rate may vary significantly from period to period. The Company's effective
tax rate may also depend upon the extent to which the Company is allowed (and is
able to use under applicable limitations) United States foreign tax credits in
respect of taxes paid on its foreign operations.
 
INFLATION
 
     The Company believes the effects of inflation generally do not have a
material adverse impact on its operations or financial condition.

                                    BUSINESS
 
GENERAL
 
     The Company is a leading provider of full-service contract research, sales
and marketing services to the global pharmaceutical, biotechnology and medical
device industries. Supported by its extensive information technology
capabilities, the Company provides a broad range of fully-integrated contract
services in order to accelerate the time from discovery to peak market
acceptance of a new therapy by offering both traditional contract research
services and also contract sales and marketing services. In addition, the
Company also supports the developing information needs of the healthcare
industry by providing health economics and healthcare policy consulting and
disease and health information management services.
 
     The Company has grown rapidly, experiencing a five year compound annual
growth rate in net revenue and net income available for common shareholders
(excluding non-recurring costs) of 53.7% and 83.4%, respectively. This growth
has been the result of internal expansion, augmented with strategic
acquisitions. In 1996, the Company's net revenue and net income available for
common shareholders, excluding non-recurring charges, was $537.6 million and
$32.1 million, respectively, provided by over 50 offices located in 20
countries, and approximately 7,375 employees. During 1996, the Company provided
services to 49 of the 50 largest pharmaceutical companies in the world, as
ranked by 1995 healthcare revenue, and the 11 largest biotechnology companies in
the world, as ranked by market capitalization in December 1996. See "-- Clients
and Marketing".
 
     Since its inception in 1982, the Company has continued to expand the scope
of its services and its geographic presence to support the needs of its clients
on a worldwide basis. The Company has implemented a number of strategic
initiatives to broaden its array of services and create new opportunities for
growth. In November 1996, the Company completed a share exchange for all of the
outstanding shares of Innovex, an international contract services organization
specializing in contract research, sales and marketing of new therapies for
pharmaceutical companies. Innovex's contract sales and marketing and clinical
research activities are concentrated on the perimarketing phase of product life,
which the Company defines as the period from two years before to two years after
regulatory approval. Innovex enables the Company to complement its clinical
research focus on obtaining regulatory approval with services designed to assist
clients in achieving market penetration of new therapies. Accordingly, with the
addition of Innovex, the Company is now able to provide late stage clinical
trials and product launch services to clients during a critical and costly stage
of bringing a product to market.
 
     Also in November 1996, the Company acquired BRI, a leading international
contract research firm specializing in medical device development and regulatory
compliance consulting. The addition of BRI allows the Company to offer contract
services to medical device developers, and consulting services relating to good
manufacturing practices ("GMP"), good clinical practices ("GCP") and good
laboratory practices ("GLP"). In May 1996, the Company acquired the operating
assets of Lewin-VHI, Inc., a nationally-recognized healthcare consulting firm,
and formed Lewin as a new subsidiary of the Company. Combined with Benefit
International, a firm specializing in pharmacoeconomic and quality of life
evaluations that was acquired by the Company in May 1995, Lewin serves as the
foundation for the Company's efforts to offer broad-based disease and health
information management services. In February 1996, the Company acquired PMC, a
CRO located in Uppsala, Sweden which has extensive clinical trials management
expertise as well as a Phase I clinical trial testing unit and an analytical
laboratory. This acquisition enabled the Company to expand its ability to
provide drug development services in Scandinavia and position the Company for
further growth in that important region for drug development. Also in 1996, in
order to increase its capacity in clinical trial drug formulation,
manufacturing, packaging and distribution, the Company began construction of a
171,000 square foot facility in Bathgate, Scotland. The Bathgate facility also
will house a clinical data management center. See "Management's Discussion and
Analysis of Financial Position and Results of Operations" and "Incorporation of
Certain Documents by Reference". See "Use of Proceeds".
 
                                       24
<PAGE>   28
 
     To facilitate the integration of these acquisitions and to capitalize on
the synergies each acquisition provides, the Company recently reorganized into
three operating divisions which work closely together to provide the Company's
services on an integrated basis. The Contract Research Division covers services
through Phase IIIa clinical trials, including study design, clinical data
management and biostatistical analysis, laboratory services, formulation and
packaging of clinical trial drugs, pre-clinical services, regulatory affairs and
medical device consulting. The Innovex Division includes perimarketing clinical
studies in Phases IIIb and IV, as well as the Company's pharmaceutical sales and
marketing services. Finally, the Lewin-Benefit Division encompasses the
Company's health economics and healthcare policy consulting and disease and
health information management services. The divisions provide an organizational
framework for the Company to cross-sell its services and enable it to offer both
product development and sales and marketing services to clients. Accordingly,
the Company believes its breadth of services strengthens its competitive
position as it looks to become the provider of choice for pharmaceutical,
biotechnology and medical device companies and the broader healthcare industry.
 
INDUSTRY OVERVIEW
 
     The CRO industry provides independent product development services
primarily for the pharmaceutical and biotechnology industries. Companies in
these industries outsource product development services to CROs in order to
manage the drug development process more efficiently and cost-effectively to
maximize the benefits in time and profit of patent-protected products. CROs
derive substantially all of their revenue from the research and development
expenditures of pharmaceutical and biotechnology companies. The CRO industry has
evolved from providing primarily pre-clinical services in the 1970s to a
full-service industry, offering services during the pre-clinical, clinical and
post-marketing phases of development for new therapies. In addition to managing
clinical trials, CROs provide scientific evaluations and analyze the results
according to good clinical and laboratory practices as required by the
applicable regulatory authorities. CROs serving the medical device industry
provide similar services designed to assist medical device developers in
obtaining regulatory approval.
 
     The Company believes that a separate industry has developed providing sales
and marketing services on a contract basis to the pharmaceutical industry.
Pharmaceutical companies incur substantial expenses on sales and marketing
activities, particularly at product launch to achieve peak market penetration.
The introduction of a new drug requires the availability of a large number of
specially-trained sales personnel, sometimes at short notice. The contract sales
industry emerged in the 1980s, most notably in the U.K. where regulatory cost
containment pressure led pharmaceutical companies to search for a more
cost-effective way to launch new products. As a result, in order to convert high
fixed costs into variable costs, large pharmaceutical companies began to
outsource their sales and marketing activities related to product launch. The
Company believes that, at present, similar cost containment dynamics are shaping
the demand for contract sales and marketing services in additional markets, such
as the United States and Germany. Large contract sales organizations can
accelerate the time to peak market acceptance of a new drug by expeditiously
assembling and training a contract sales force to launch a pharmaceutical
company's newly approved products. Contract sales organizations are able to
recruit the necessary personnel by utilizing extensive databases of
pharmaceutical sales representatives. The Company believes that contract sales
and marketing opportunities could emerge in the medical device and biotechnology
industries as well.
 
     The Company believes that there is a significant market opportunity for
companies focusing on the perimarketing phase of a product life cycle. The
perimarketing period is characterized by significant spending on large scale
clinical trials and sales staff requirements necessary to gain commercial
acceptance of products. The Company believes that organizations offering
integrated product development and sales and marketing services during the
perimarketing period will be able to further shorten the product development
cycle and accelerate market penetration so that drug sponsors can maximize the
duration of a drug's commercial life under patent protection, and therefore
maximize related revenue and return on investment. Accordingly, the Company
believes that such organizations will have a competitive advantage over
companies that compete only in either the CRO or contract sales industries.
 
                                       25
<PAGE>   29
 
     The CRO industry is highly fragmented, consisting of several hundred small,
limited-service providers, several medium-sized CROs and only a few companies
with full-service global capabilities. The contract sales and marketing industry
also is highly fragmented, primarily characterized by local organizations
operating within their home countries. Prior to its combination with the
Company, Innovex was the largest contract sales organization in the U.K. and was
expanding its services into international markets, particularly in the United
States and Germany. The Company believes that, through its combination with
Innovex, it is the leading global organization to combine the full spectrum of
services typically offered by the CRO industry with contract sales and marketing
services.
 
TRENDS AFFECTING OUTSOURCING
 
     Worldwide spending on pharmaceutical products and medical devices is
increasing due to a combination of factors, including aging populations and a
growing number of pharmaceutical and medical device products that provide
enhanced therapeutic benefits. At the same time, regulatory pressures and
pricing constraints have intensified as governments and private healthcare
payors seek to manage the growth of total healthcare expenditures. These
developments have led to intense competition in the pharmaceutical,
biotechnology and medical device industries, where innovation, more focused
research and development, rapid product introduction and cost-effectiveness have
become key competitive factors. The Company believes that in response to these
developments, pharmaceutical, biotechnology and medical device companies are
increasingly outsourcing a variety of activities associated with product
development and pharmaceutical sales and marketing to specialist third party
service providers such as the Company. Although outsourcing has been prevalent
for long periods of time in many industries, outsourcing to CROs and contract
sales organizations is a relatively recent trend and one that is still evolving.
Through such outsourcing, drug and medical device developers are attempting to
reduce fixed costs and accelerate the time to market, commercial acceptance and
market penetration of their products, with the aim of maximizing their return on
investment.
 
     The Company estimates that 1995 global expenditures by the pharmaceutical
and biotechnology industries on drug development services of the type offered by
the CRO industry were approximately $25 billion of which approximately $2.5
billion were outsourced to CROs. Based upon industry data, the Company believes
that global expenditures on sales and marketing services of the type offered by
the contract sales industry are greater than expenditures on drug development,
and that the percentage currently outsourced is estimated to be smaller than the
percentage of outsourced drug development services. The Company believes that
the following factors will contribute to the increased use of drug development
and contract sales and marketing outsourcing and an expansion of the scope of
services outsourced:
 
     COMPETITIVE PRESSURES TO CONTAIN COSTS AND ACCELERATE TIME TO MARKET.  Over
the last several years, pharmaceutical companies have faced significant margin
pressures from patent expirations, market acceptance of generic drugs,
regulatory pressures to reduce drug prices and market forces, particularly
managed care. The pharmaceutical industry is consolidating as companies seek to
reduce costs and increase revenues through business combinations. As a result,
many pharmaceutical companies have focused on more efficient ways of conducting
business and on research innovation to ensure future product pipeline. The need
to increase the speed of new product development and market acceptance has
become paramount in order to maximize the period of marketing exclusivity for
patent-protected products. Increasingly, pharmaceutical companies have turned to
outsourcing both as a means of reducing fixed costs and accelerating the drug
development process. The Company believes large drug sponsors also are moving
toward outsourcing greater portions of a new product's development to a single,
multinational full-service provider, rather than contracting specific phases to
several different providers. The Company believes that outsourcing providers
with the ability to provide fully-integrated services on a multinational basis
for the entire product continuum from discovery to peak marketing will benefit
from this trend.
 
     GLOBALIZATION OF THE MARKETPLACE.  Pharmaceutical, biotechnology and
medical device companies are increasingly attempting to expand the market for
new products by pursuing regulatory approvals and
 
                                       26
<PAGE>   30
 
commercialization in multiple countries simultaneously rather than sequentially
as they have in the past. Expanding the market for a drug or medical device is
particularly important because of limited patent lives and high development
costs. However, building and maintaining the internal infrastructure to pursue
regulatory approval and commercialization in smaller markets is costly for these
companies. The Company believes that in order to respond to these pressures and
gain access to the global marketplace, pharmaceutical, biotechnology and medical
device companies are increasingly outsourcing to service providers that are
established in key geographic markets worldwide and that are capable of
coordinating concurrent regulatory approvals or serving as the developer's
presence in a particular country. The Company believes that organizations with
advanced global data management capabilities, global presence, the ability to
prepare regulatory submissions in multiple jurisdictions and the ability to
offer sales and marketing support will benefit from these trends.
 
     IMPORTANCE OF SALES AND MARKETING ACTIVITIES.  In addition to expenditures
on research and development, pharmaceutical and biotechnology companies incur
substantial expenditures on sales and marketing activities. Such expenditures
are especially concentrated from the time of product launch through market
penetration. During this period, pharmaceutical and biotechnology companies
generally require the availability of a large number of specially-trained sales
personnel on short notice for a limited duration. Additionally, these companies
engage in specialized marketing of their products to prescribers and other
decision makers, such as managed care providers and other intermediaries, in
order to persuade them to prescribe their product in preference to alternative
drugs, or to include their product in the list of drugs (the "formulary") that
affiliate physicians may prescribe. Cost containment pressures have accelerated
the use of third party services to provide specialized sales and marketing teams
in certain European countries, and the Company believes similar trends in the
United States will drive the expansion of the United States market for such
services. The Company believes that pharmaceutical and biotechnology companies
will increasingly turn to third-party service providers capable of replicating
or supplementing the internal sales and marketing functions of the large drug
companies as a variable cost alternative to developing and maintaining such
resources in-house. Additionally, the Company believes that biotechnology
companies will increasingly turn to outsourcing for sales and marketing services
as an alternative to entering into licensing arrangements with large
pharmaceutical companies that may limit the drug developer's ability to maximize
profits from commercialization of the product.
 
     INCREASINGLY STRINGENT REGULATION; NEED FOR SOPHISTICATED INFORMATION
TECHNOLOGY.  Increasingly stringent regulatory requirements throughout the world
have increased the volume of data required for regulatory filings and escalated
the demands for data collection and analysis during the drug and medical device
development processes. Pharmaceutical companies, often developing drugs in
therapeutic areas where other drugs are already marketed, need larger, more
complicated trials to demonstrate superiority over existing therapies. As
regulatory requirements become more stringent and the need for advanced
technological capabilities becomes more important, the pharmaceutical,
biotechnology and medical device industries are outsourcing to organizations
with strong data management capabilities to take advantage of their
technological expertise.
 
     In addition to increasingly stringent regulatory requirements, the Company
believes that recent efforts to develop global harmonized regulatory standards
will increase the importance of advanced information technology capabilities in
global drug development. In recent years, the FDA and corresponding regulatory
agencies of Canada, Japan and Europe have commenced discussions for the purpose
of developing harmonized standards for both the conduct of pre-clinical and
clinical studies and the format and content of applications for new drug
approval. Further, the FDA encourages the use of computer assisted filings in an
effort to expedite the approval process. The Company believes that organizations
with expertise in information technology and in the changing regulatory
environment will have a competitive advantage.
 
     GROWTH IN BIOTECHNOLOGY AND GENOMICS INDUSTRIES.  The United States
biotechnology and genomics industries have grown rapidly over the last 10 years
and are developing significant numbers of new therapies which will increasingly
enter clinical trials. Many biotechnology and genomics companies do not have the
necessary staff, in-house expertise or financial resources to conduct clinical
trials or to
 
                                       27
<PAGE>   31
 
market and sell products as they gain regulatory approval and therefore are
looking to outsourcing as a cost-effective alternative. As more biotechnology
and genomics products receive regulatory approvals, the Company believes that
demand for outsourced sales and marketing services will increase. Moreover, the
biotechnology and genomics industries are expanding in Europe, and the Company
believes that such industries will expand in the Asia-Pacific region as
governments in that region adopt policies favorable to the development of
biotechnology products.
 
     MEDICAL DEVICE INDUSTRY GROWTH.  The medical device industry worldwide has
grown rapidly over the last two decades. Many new products and technologies are
currently under development, creating within the medical device industry a need
for more regulatory and clinical trial expertise. At the same time, requirements
for government approval of medical devices have become increasingly stringent.
The Company believes that medical device development companies are increasingly
outsourcing for expertise in complex technologies, global clinical program
management and reimbursement and regulatory compliance. The Company believes
that a company with expertise in medical device development will have a
competitive advantage as outsourcing increases.
 
COMPANY STRATEGY
 
     The Company's strategy is to provide a continuum of fully-integrated
contract services globally across key therapeutic categories for the rapid and
cost-effective development and marketing of products for the pharmaceutical,
biotechnology and medical device industries. The Company believes that it is
able to address the significant and expanding outsourcing needs of these markets
as its services span the entire product development and launch process from the
pre-clinical stage to the ultimate sales and marketing of the products.
Therefore, the Company continues to expand its geographic presence, service
offerings and therapeutic specializations through internal growth and strategic
acquisitions while continuing to invest in sophisticated information technology
critical to meeting the complex needs of its clients. This strategy has driven
the rapid growth of the Company and continues to provide for future growth
opportunities. In addition, in conjunction with its Lewin-Benefit Division, this
strategy provides a platform for the Company to become a significant provider of
health economics and healthcare policy consulting and disease and health
information management services to product manufacturers and healthcare service
providers. The main components of the Company's strategy are:
 
     PROVIDE A BROAD ARRAY OF FULLY-INTEGRATED CONTRACT SERVICES.  The Company,
as part of its strategy to provide a broad array of fully-integrated contract
services to the pharmaceutical, biotechnology and medical device industries, has
increased its range of services to encompass the continuum from discovery
through commercial acceptance of products. The Company believes that the ability
to offer such a full spectrum of contract services distinguishes it from
organizations limited to providing only contract clinical research or contract
sales and marketing services. This strategy enables the Company to cross-sell
its services more comprehensively. In addition, as large pharmaceutical clients
move towards forming alliances with preferred outsourcing organizations, the
Company believes that such clients will seek to form relationships primarily
with the largest, most innovative full-service third party service providers.
 
     ENHANCE THERAPEUTIC AREA SPECIALIZATION.  The Company believes that it is
better able to serve its pharmaceutical and biotechnology clients' needs by
offering therapeutic specializations within its full range of drug development
and promotional services. As pharmaceutical and biotechnology companies attempt
to get drugs to market and to achieve market penetration faster, the Company
believes that the ability to provide specialized therapeutic expertise is
necessary to compete for clients' business. The Company has specialized business
units and extensive expertise in the therapeutic areas of central nervous
system, cardiovascular, infectious, and respiratory diseases as well as in the
field of oncology. The Company also has significant clinical trials experience
in the therapeutic areas of endocrinological, gastroenterological and
genito-urinary and musculoskeletal diseases. The Company has broadened its
therapeutic expertise both internally and through acquisitions and considers
strategic acquisitions on an ongoing basis to further strengthen its therapeutic
specializations.
 
                                       28
<PAGE>   32
 
     EXPAND GEOGRAPHIC PRESENCE.  The Company believes that the capability to
provide its services in most major and developing pharmaceutical markets
enhances its ability to compete for business from large multinational
pharmaceutical and biotechnology companies. With over 50 offices in 20
countries, the Company believes that it is a leader in pharmaceutical
outsourcing in its ability to provide global services. Recently, the Company has
focused on expanding its presence in the Asia-Pacific region and has formed a
joint venture with a company in India and is exploring opportunities for similar
ventures in China.
 
     INCREASE PENETRATION OF PERIMARKETING SERVICES.  The Company believes that
its expertise in providing contract services during the perimarketing phase
provides a significant opportunity for growth. The Company's perimarketing
services include Phase IIIb and IV clinical trials, which focus on product
efficacy and product sales and marketing services. Pharmaceutical and
biotechnology companies typically spend significant funds on a product during
the perimarketing phase. The Company's strategy is to expand its perimarketing
services, particularly in the United States and Europe, by leveraging its strong
presence in those markets where the Company is currently providing clinical
research services. The Company may develop sales and marketing services for a
particular market internally or acquire existing local sales and marketing
service providers. The Company intends to cross-sell its perimarketing services
to its existing contract research clients in those markets, as well as to
attract new clients who are interested only in outsourcing the high costs
associated with perimarketing activities.
 
     EXTEND LEADERSHIP IN INFORMATION TECHNOLOGY.  The Company seeks to extend
its leadership in information technology in order to provide state-of-the-art
drug and medical device development, perimarketing and health information
management services on a worldwide basis. The Company believes that it has built
an extensive and effective global information technology network for gathering,
managing and analyzing clinical trials data and that its information technology
provides a competitive advantage. Fundamentally, the Company's information
technology supports its transnational structure by enabling all offices to
exchange information with each other so that several offices worldwide can work
simultaneously on a project. This network enables the Company's new offices to
begin contributing immediately to the Company's transnational projects. The
Company's data systems are able to concurrently compile and analyze large
volumes of data from multinational trials and prepare regulatory submissions for
filings on a global basis. The Company also uses its extensive information
technology network to support its contract sales and marketing services. The
Company has a sophisticated system for the centralized management of sales
activities across a broad geographic area, as well as an advanced system to
facilitate the recruitment of sales representatives and assembly of sales forces
on short notice from a database of 54,000 sales representatives. The Company
believes that these systems bring added value to its clients by significantly
enhancing its ability to assemble a targeted sales force on an expedited basis
and accelerate the time to product launch.
 
     CAPITALIZE ON THE GROWING IMPORTANCE OF HEALTH ECONOMICS AND DISEASE
INFORMATION MANAGEMENT SERVICES IN THE HEALTHCARE INDUSTRY.  The Company is
positioning itself to capitalize on the growing importance of health economics
and healthcare policy consulting and disease and health information management
services by leveraging its capabilities and expertise to provide information-
based healthcare services. In a rapidly changing healthcare environment
dominated by managed care, the healthcare industry is focusing on methods of
providing quality care at a lesser cost. Thus, the ability to measure healthcare
outcomes and apply cost-benefit analysis to the treatment of diseases has
substantial value to many interests in the healthcare industry. The Company
believes that its capabilities in health economics consulting and disease
management information services, through its Lewin-Benefit Division, position it
to serve the emerging needs of not only managed care organizations, hospitals,
governments, healthcare providers and insurance companies, but also product
manufacturers, in the development of cost-effective integrated healthcare
solutions.

SERVICES
 
     The Company provides globally integrated contract research, sales and
marketing services to the pharmaceutical, biotechnology and medical device
industries. The Company also offers health economics and healthcare policy
consulting and disease and health information management services.
 
     The Company provides its clients with a continuum of services that develop
a laboratory discovery into a product sale. The Company is organized in three
operating divisions that interface with the client at complementary points in
the process. Within the divisional structure, there is considerable overlap in
specific services and a free flow of communication to best meet each client's
needs. Traditional CRO services range from pre-clinical testing to Phase IIIa
clinical trials and are handled by the Contract Research Division. Once the
product has reached Phase IIIb clinical trials and is therefore in the
perimarketing period, client services generally are provided by the Innovex
Division. These two divisions generate significant amounts of data that are
processed and analyzed by a sophisticated information technology system.
Information technology is at the core of the Company's operations because it
enhances the quality of the Company's services and allows the free flow of
information between the divisions that is key to maximizing the value delivered
by the Company. In addition, the data can be used and further developed by the
Lewin-Benefit Division, which handles disease and health information management.
These concepts are illustrated by the following chart:
 
                                     chart
 
     The Company's services are described in greater detail below.
 
  CONTRACT RESEARCH SERVICES
 
     CLINICAL TRIAL SERVICES.  The Company offers comprehensive clinical trials
services which are the basis for obtaining regulatory approval for drugs and
medical devices. The Company has specialized business units and extensive
experience in the therapeutic areas of the central nervous system,
cardiovascular, infectious and respiratory diseases and the field of oncology.
The Company also has significant clinical trials experience in the therapeutic
areas of endocrinological, gastroenterological and genitourinary and
musculoskeletal diseases. The Company is experienced in managing large trials
involving several thousand patients at several hundred sites and in
multinational trials conducted simultaneously in the Americas, Europe, the
Asia-Pacific region and South Africa.

as rectangles of various sizes.  The second column is a rectangle which is as
long as the arrow in the first column and is divided into two unequal portions
by a dotted line even with "Phase IIIb Trials" inside the arrow.  This column
shows how the services listed in the arrow are divided between the Company's
CRO Services and Perimarketing Services.  Approximately one-half of the
rectangle above the dotted line corresponds to the Company's CRO services and
is labelled "CRO Services" and the remaining portion of the rectangle
corresponds to the Company's perimarketing services and is labelled
"Perimarketing Services."  The third column, made up of a rectangle as long as
the rectangle in the second column, simply labelled as "Information
Technology," illustrates that the Company's information technology is an
integral part of all the Company's services and the interface between them. 
Two double arrows point each way between columns two and three; similarly, a
double arrow points each way between columns three and four, which contains a
square, approximately one-fourth the length of the rectangles in columns two
and three, that represents the Company's disease and health information
management services and is titled "Disease and Health Information Management."

     The Company provides its clients with one or more of the following core
clinical trials services:
 
          Study Design.  The Company uses its broad development expertise to
     serve its clients in the critical area of study design by assisting in the
     preparation of the study protocol and design of case report forms ("CRFs").
     The protocol defines the medical issues to be examined, the number of
     patients required to produce statistically valid results, the period of
     time over which they must be tracked, the frequency and dosage of drug
     administration and the study procedures. The study's success often depends
     on the protocol's ability to predict correctly the requirements of the
     applicable regulatory authorities.
 
          Investigator Recruitment.  During clinical trials, the drug is
     administered to patients by physicians, also referred to as investigators,
     at hospitals, clinics or other locations, also referred to as sites. The
     Company's ability to identify and recruit investigators with the
     appropriate expertise and an adequate base of patients who satisfy the
     requirements of the study protocol is critical to the success of the trial.
     The Company has access to several thousand investigators who have conducted
     clinical trials worldwide for the Company.
 
          Study Monitoring.  The Company provides study monitoring services
     which include investigational site initiation, patient enrollment
     assistance and data collection and clarification. Site visits serve to
     assure the quality of the data which are gathered according to GCP and to
     meet the sponsors' and regulatory agencies' requirements as specified in
     the study protocol.
 
          Clinical Data Management and Biostatistical Services.  The Company's
     clinical data management and biostatistical services were the original
     foundations of the Company, and the Company believes that they are two of
     the Company's primary competitive strengths. The Company has extensive
     experience in the United States and Europe in the creation of scientific
     databases for all phases of the drug development process, including the
     creation of customized databases to meet client-specific formats,
     integrated databases to support New Drug Application ("NDA") submissions
     and databases in accordance with FDA and European specifications. The
     Company believes that its global database capabilities are a significant
     competitive advantage, particularly in large-scale multi-jurisdictional
     trials involving thousands of patients at hundreds of sites. For example,
     during 1996 the Company managed the NDA submission process for six
     large-scale programs. The largest program included approximately 3,000
     patients located throughout the United States, Europe and Japan.
 
          Phase I Services.  The Company has Phase I units located in London,
     England, Uppsala, Sweden, Freiburg, Germany and Lenexa, Kansas. The
     services offered by these units include dose ranging,
     bioavailability/bioequivalence studies, pharmacokinetic/pharmacodynamic
     modeling, first administration to humans, multiple dose tolerance, dose
     effect relationship and metabolism studies. Because its Phase I units focus
     primarily on studies for new, innovative products, rather than generics,
     the Company believes there is greater opportunity for winning contracts for
     larger, later stage studies of such innovative products.
 
     In addition to the Company's core clinical trials management services, the
Company provides its clients with the following specialized services:
 
          Centralized Clinical Trial Laboratory.  In addition to providing
     comprehensive safety and efficacy testing for clinical trials, the
     Company's centralized clinical trial laboratory provides site-specific
     study materials, customized lab report design and specimen archival and
     management on behalf of a study sponsor. The centralized laboratory offers
     a 48-hour turnaround time for laboratory results and is capable of
     providing direct electronic integration of laboratory data into safety and
     efficacy reports for NDA submissions.
 
          Formulation, Manufacturing and Packaging Services.  The Company offers
     services in the design and development of pharmaceutical dose forms as well
     as the manufacture of study drug and placebos and the appropriate packaging
     of these for double blinded studies. These services can expedite the drug
     development process because clinical trials are often postponed by delays
     in the
 
                                       31
<PAGE>   36
 
     manufacture of study drug materials. The Company is expanding its capacity
     for delivering these services through the construction of a new 171,000
     square foot facility at Bathgate, Scotland which the Company believes will
     be one of the largest specialist clinical trial supplies units in the
     world. The Company anticipates construction will be completed in late 1997.
     The facility also will house a clinical data management center. See
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations -- Overview" and "Use of Proceeds".
 
     PRE-CLINICAL SERVICES.  The Company's pre-clinical unit in Edinburgh,
Scotland is part of a drug development facility acquired by the Company in 1995
from Syntex Pharmaceuticals Limited. This unit, combined with the Company's
pre-clinical facility in Ledbury, England, provides clients with a wide array of
pre-clinical and toxicology services. These services are designed to produce the
data required to identify, quantify, and evaluate the risks to humans resulting
from the manufacture or use of pharmaceutical and biotechnology products,
including developmental and reproductive toxicology, genetic toxicology,
neurotoxicology, carcinogenicity testing, pharmacology, analytical chemistry,
pathology, metabolism and pharmacokinetics.
 
     REGULATORY AFFAIRS SERVICES.  The Company provides comprehensive medical
and regulatory services for its pharmaceutical and biotechnology clients. The
Company's medical services include medical oversight of studies, review and
interpretation of adverse experiences, medical writing of reports and study
protocols and strategic planning of drug development programs. Regulatory
services for product registration include regulatory strategy design, document
preparation, consultation, and liaison with various regulatory agencies. The
Company's regulatory affairs professionals help to define the steps necessary to
obtain registration in the most expeditious manner. The Company is able to
provide such services in numerous countries to meet its clients' needs to launch
products in multiple countries simultaneously.
 
     MEDICAL DEVICE SERVICES.  With its acquisition of BRI in November 1996, the
Company believes it obtained a leading international contract research firm
specializing in medical devices and regulatory consulting. The Company's service
offerings include: review of global strategies for device development and
introduction; identifying regulatory requirements in targeted markets; clinical
study design and planning; data management; statistical analysis of report
preparations; global clinical trial management and monitoring capabilities;
consultation on quality control and quality assurance issues; regulatory
filings; compliance with United States, European and European Union regulations
relating to medical devices; long-range planning for multinational product
launches; compliance with legislative requirements for market access;
post-marketing requirements; managing relationships with national governments
and regulatory authorities; European pricing strategies; and European personnel
and recruitment services.
 
  PERIMARKETING SERVICES (INNOVEX)
 
     The Company provides services to the pharmaceutical industry with a
strategic focus on the commercial launch of new drugs. These services include
contract sales, marketing and Phases IIIb and IV clinical trials. The Company
believes that there is significant potential for future growth in the market for
such contract services. The Company is well-positioned to benefit from this
opportunity by cross-selling its sales and marketing outsourcing capabilities to
its contract research clients. Similarly, the Company believes that its existing
and new sales and marketing relationships will benefit its future contract
research opportunities.
 
     SALES AND MARKETING SERVICES.  The Company offers a flexible range of
contract sales services which are delivered through dedicated and syndicated
sales teams. Dedicated sales teams are comprised of sales representatives
recruited by the Company in accordance with client specifications to conduct
sales efforts for a particular client. Dedicated sales teams can be managed by
the Company or can report directly to the client, depending on client
preference. In certain circumstances, the Company can transfer an entire
dedicated sales team to the client for an additional placement fee. Syndicated
sales teams promote a number of drugs for different clients and are generally
managed directly by the Company. The Company's contract sales teams form a
highly skilled network of professionals that afford
 
                                       32
<PAGE>   37
 
clients substantial flexibility in selecting the extent and cost of promoting
products as well as their level of involvement in managing the sales effort.
 
     The Company believes that speed of recruitment, quality of training and
management of sales representatives, supported by advanced information
technology, are key to providing clients with a sales force tailored to meet
their geographic and scheduling needs. The Company's ability to assemble a sales
team quickly is a product of combining the talents of experienced personnel for
screening and interviewing candidates with the use of information technology,
such as scanning and resume tracking systems, to expedite recruitment. In the
United States, the Company maintains an electronic database of 54,000 resumes
and has recruited as many as 125 sales representatives per week. In addition,
the Company has established relationships with specialist healthcare recruitment
agencies in Europe, particularly the U.K., and the United States to assist in
its recruiting efforts. A client-specific national sales force can be recruited
by the Company in as few as eight weeks, whereas the Company believes
pharmaceutical companies often take six to nine months to build an internal
sales force. Sound hiring procedures, such as the Company's candidate assessment
program, background screenings and drug testing programs, supplemented by the
Company's internal training and development programs, help to ensure the quality
of recruited personnel. Once the sales teams are assembled, the Company uses its
electronic territory management system ("ETMS") to enhance the speed,
effectiveness and accountability to clients of its contract sales activities.
This system is currently being used in the United States and is being
implemented in the U.K. The Company intends to further expand the use of ETMS in
the U.K. and internationally in 1997.
 
     The Company also provides a range of specialized marketing services
specifically for pharmaceutical companies aimed at influencing the decisions of
patients and physicians and accelerating the acceptance of drugs into treatment
guidelines and formularies. Such services are typically purchased by the
marketing departments of pharmaceutical companies, however, marketing of new
products often receives substantial attention from senior executives, creating
an opportunity for the Company to interact with the strategists of the
pharmaceutical industry. The Company believes that its commercial orientation,
clinical and promotional expertise and international experience enable it to
tailor programs to specific client needs in a wide range of geographic markets
and therapeutic areas.
 
     The market for outsourced contract sales and marketing services in the
pharmaceutical industry has been predominantly national in nature and is most
highly developed in the U.K. where the Company estimates that one out of every
four pharmaceutical sales representatives is a contract sales representative. In
1996 the Company derived $76.7 million of its net revenue from contract sales
and marketing services of its U.K. operations. The Company believes that
contract sales and marketing generally is more developed in the U.K. because
regulatory cost containment pressures occurred much earlier there than in other
markets. Although there is a much lower level of market penetration for
outsourced sales and marketing services in most other countries, the market has
been growing, particularly in the United States and Germany, where increased
cost containment pressures have emerged. Net revenue from the Company's contract
sales and marketing services in the United States and Germany for 1996 was $55.4
million and $14.4 million, respectively. The Company also currently offers
contract sales and marketing services in The Netherlands, Sweden and Spain and
is seeking to develop such services in other parts of the world.
 
     CONTRACT RESEARCH SERVICES.  The Company also provides contract research
services, primarily for Phase IIIb and Phase IV clinical trials during the
perimarketing period. The Company believes that this focus on Phase IIIb and
Phase IV trials complements the Company's sales and marketing activities and
enables the Company to integrate marketing considerations with the design of
late stage clinical research protocols. The Company believes this coordination
between clinical investigators and marketing professionals enables it to provide
added value during the sales and marketing of a product.
 
                                       33

business in the highly regulated healthcare environment. The Company has over
100 consultants, including clinicians, economists, marketing professionals and
former high-level government executives with experience in the private sector,
providing interdisciplinary skills and expert capabilities in corporate
strategic planning and management, program and policy development, financial and
cost-effectiveness analysis, evaluation design, microsimulation modeling and
data analysis across five general practice areas: public health and finance
policy, healthcare organizations, economic analysis, managed care and medical
technology. The Company has access to more than 76 healthcare-related databases
and has developed the expertise to analyze such complex data to respond to its
clients' information needs. These services represent the core competencies of
Lewin, a nationally-recognized healthcare consulting firm acquired by the
Company in 1996. The Company believes that it can leverage Lewin's reputation,
expertise and access to providers and policymakers to cross-sell its other
health economics and information management services beyond its current market.
 
     HEALTH ECONOMICS CONSULTING AND DISEASE INFORMATION MANAGEMENT
SERVICES.  The Company's health economics consulting and disease information
management services focus on applying healthcare outcomes analysis to the
economic valuation of drugs and the treatment of diseases using data generated
from its clinical trials services. These services enable regulators, health care
providers and third parties to assess the pricing and cost-effectiveness of new
medical therapies. The Company believes that such economic valuation of drugs
will play an important role in the future determination of drug pricing.
Additionally, France, Germany, the U.K., Canada and Australia require
cost-benefit analyses in regulatory submissions, and the Company believes that
other countries may adopt similar requirements in the future. The Company
believes that it will benefit from cross-selling these services to its
pharmaceutical and biotechnology clients which are subject to pressures from
managed care providers and regulators to demonstrate the cost-effectiveness of
new products.
 
     PLATFORM FOR FUTURE GROWTH.  The Company is positioning itself to serve as
a health information interface between the users of healthcare services and the
developers of healthcare treatments by developing health information management
services designed to evaluate alternative healthcare solutions and provide third
parties with the tools to select among them. While hospitals and healthcare
provider organizations are placing intense pressure on the prices of products
and services, the public is highly concerned about the resulting quality of
care. The Company believes that purchasers of healthcare services, such as
individuals and employers, as well as public interest groups and governments,
are becoming increasingly interested in the value of care, as a function of its
cost and level of quality, and, accordingly, are seeking ways to measure and
weigh the value of various healthcare alternatives.
 
INFORMATION TECHNOLOGY
 
     All of the Company's services are enhanced by the Company's ongoing
investment in information technology. The Company believes that it was a pioneer
in the CRO industry in building a comprehensive global information technology
network for gathering, managing and analyzing clinical trials data. The
Company's information technology systems consist of a wide area network linking
approximately 50 local area networks and interconnecting over 6,000
microcomputers worldwide. The Company continues to improve and expand this
network, supported by the development of data management software to
 
                                       34
<PAGE>   39
 
further streamline the drug development process. The Company's network enables
the exchange of information among the Company's offices on a worldwide basis,
facilitating concurrent multinational clinical trials and regulatory
submissions. In addition, through the Company's innovative systems, clients are
able to gain direct access to key data with respect to their products in
testing, such as adverse events, CRFs and clinical laboratory testing results on
a current basis. Clients using the Company's sales and marketing services can
access information related to sales calls and provide feedback about the
performance of the Company's sales representatives. The Company's sales and
marketing services are further supported by its ETMS for planning, targeting,
reporting, analysis and communications of sales and marketing activities,
allowing the Company to centralize management of sales activities across a broad
geographic area. The Company currently uses this system in the United States and
is implementing it in the U.K. The Company intends to further expand the use of
ETMS in the U.K. and internationally in 1997. Additionally, the Company utilizes
an enhanced system for screening and tracking resumes as the cornerstone of its
efforts to rapidly recruit qualified sales representatives.
 
     Some of the Company's internally developed systems which facilitate its
drug development services, sales and marketing services and overall business
management are described below:
 
<TABLE>

</TABLE>
 
     The Company's information technology systems are supported by approximately
170 employees worldwide who are committed to the ongoing development of
technology solutions to support the Company's services on a worldwide basis. See
"-- Strategy -- Extend Leadership in Information Technology".
 
CLIENTS AND MARKETING
 
     The Company coordinates its business development efforts across its service
offerings through a central business development function. The Company believes
that it is best able to capitalize on the synergies arising from its broad array
of fully-integrated contract services by cross-selling its services at a
centralized level. In addition, the Company believes that this structure allows
the Company to serve its clients more effectively, while permitting the
divisions to focus on the services provided.
 
     The Company's business development function directs the activities of
business development personnel in each of the Company's United States locations
as well as the Company's locations in the U.K., Belgium, Canada, France,
Germany, Ireland, Italy, Japan, the Netherlands, Argentina, Denmark, Australia,
Spain, Sweden and Singapore. Most of the Company's business development
personnel have technical or scientific backgrounds and many are physicians,
pharmacologists, statisticians or regulatory affairs professionals. The Company
coordinates its worldwide marketing efforts through a computerized system
integrated into each of the Company's offices that is actively marketing
services.
 
     The Company provides its clinical research services and sales and marketing
services on a global basis to the pharmaceutical, biotechnology and medical
device industries. In addition, the Company provides health economics and
healthcare policy consulting and disease and health information management
services to the United States healthcare industry and governments. For the year
ended December 31, 1996, approximately 43.8% of the Company's net revenue was
attributed to operations in the Americas, 53.8% to European operations and 2.4%
to Asia-Pacific operations. The Company has
 
                                       35
<PAGE>   40
 
provided services during 1996 to 49 of the 50 largest pharmaceutical companies
in the world, as ranked by 1995 healthcare revenue, and to the 11 largest
biotechnology companies in the world, as ranked by market capitalization in
December, 1996. In 1996, the Company represented over 300 clients, including
some of the largest American, European and Japanese pharmaceutical companies.
 
     In 1996, Sandoz AG accounted for 11.9% of the Company's consolidated net
revenue. The Company has in the past derived, and may in the future derive, a
significant portion of its net revenue from a relatively limited number of major
projects or clients. Concentrations of business in the CRO industry are not
uncommon and are increasing as large pharmaceutical companies are outsourcing
larger projects to fewer full-service providers. The Company is likely to
experience such concentration in future years. See "Risk Factors -- Dependence
on Certain Industries and Clients".
 
COMPETITION
 
     The market for the Company's contract research services is highly
competitive, and the Company competes against traditional CROs, the in-house
research and development departments of pharmaceutical companies, as well as
universities and teaching hospitals. Within the CRO industry, there are several
hundred small, limited-service providers, several medium-sized firms, and only a
few full-service companies with global capabilities. The Company believes that
it is the only company offering full-service contract research services with
annualized net revenue exceeding $500 million. Consolidation in the CRO industry
will likely result in greater competition among the larger contract research
providers for clients and acquisition candidates. The Company's primary contract
research competitors include Covance Pharmaceutical Product Development, Inc.,
PAREXEL International Corp. and ClinTrials Research, Inc. In sales and marketing
services, the Company competes against the in-house sales and marketing
departments of pharmaceutical companies and small local contract sales
organizations in each country in which it operates. The Company also competes
against consulting firms offering healthcare consulting services, including
boutique firms specializing in the healthcare industry and the healthcare
departments of large firms.
 
     Competitive factors for contract research services include previous
experience, medical and scientific experience in specific therapeutic areas, the
quality of contract research, the ability to organize and manage large-scale
trials on a global basis, the ability to manage large and complex medical
databases, the ability to provide statistical and regulatory services, the
ability to recruit investigators, the ability to integrate information
technology with systems to improve the efficiency of contract research, an
international presence with strategically located facilities, financial
viability, and price. The primary competitive factors affecting contract sales
and marketing services are the ability to quickly assemble, train and manage
large qualified sales forces to handle broad scale launches of new drugs and
price. Competitive factors affecting healthcare consulting services include
experience, reputation, access to data, ability to analyze data and price. The
Company believes that it competes favorably in these areas. In addition, the
Company believes that the synergies arising from integrating contract research
services with contract sales and marketing services, supported by global
operations and information technology, differentiate the Company from its
competitors.
 
EMPLOYEES
 
     The Company has approximately 7,375 employees, comprised of approximately
3,325 in the Americas, 3,925 in Europe and Africa and 125 in the Asia-Pacific
region, and over 50 offices in 20 countries.

                          DESCRIPTION OF CAPITAL STOCK
 
COMMON STOCK
 
     The Company has authorized 200 million shares of Common Stock, $.01 par
value per share. As of December 31, 1996, 33,149,962 shares of Common Stock were
issued and outstanding and beneficially held by approximately 8,950
shareholders. Holders of Common Stock are entitled to one vote for each share
held on matters which are submitted to a vote of shareholders and are not
entitled to cumulative voting in the election of directors. Subject to any
preferential rights of holders of Preferred Stock, holders of Common Stock are
entitled to receive dividends, if any, as declared from time to time by the
Board of Directors out of assets legally available for such purpose. See "Price
Range of Common Stock and Dividend Policy". On liquidation, holders of Common
Stock are entitled to a pro rata portion of all assets available for
distribution after payment of creditors and the liquidation preference of any
outstanding shares of Preferred Stock. Holders of Common Stock have no
preemptive rights or other rights to subscribe for additional shares. All
outstanding shares of Common Stock are, and the shares offered hereby will be,
upon issuance, validly issued, fully paid and non-assessable.
 
PREFERRED STOCK
 
     The Company has authorized 25 million shares of Preferred Stock, $.01 par
value per share, none of which has been issued. The Company may issue shares of
Preferred Stock in one or more series as may be determined by the Company's
Board of Directors, who may establish, from time to time, the number of shares
to be included in each series, may fix the designation, powers, preferences and
rights of the shares of each such series and any qualifications, limitations or
restrictions thereof, and may increase or decrease the number of shares of any
such series without any further vote or action by the shareholders. Any
Preferred Stock so issued by the Board of Directors may rank senior to the
Common Stock with respect to the payment of dividends or upon liquidation,
dissolution or winding up of the Company, or both. In addition, any such shares
of Preferred Stock may have class or series voting rights. Under certain
circumstances the issuance of Preferred Stock or the existence of the unissued
Preferred Stock may tend to discourage or render more difficult a merger or
other change in control of the Company.
 
CERTAIN ARTICLES OF INCORPORATION AND BYLAWS PROVISIONS HAVING POTENTIAL
ANTI-TAKEOVER EFFECTS
 
  General
 
     A number of provisions of the Company's Articles of Incorporation and
Bylaws address matters of corporate governance and the rights of shareholders.
The following summary of such provisions is not intended to be complete and is
qualified in all respects by the Company's Articles of Incorporation and Bylaws.
Certain of these provisions, as well as the ability of the Board of Directors to
issue shares of Preferred Stock and to set the voting rights, preferences and
other terms thereof, may delay or prevent takeover attempts not first approved
by the Board of Directors (including takeovers which certain shareholders may
deem to be in their best interests.) These provisions also could delay or
frustrate the removal of incumbent directors or the assumption of control by
shareholders. All references to the Company's Articles of Incorporation refer to
the Company's Amended and Restated Articles of Incorporation in effect as of the
date of this Prospectus.
 
  Classification of Board of Directors
 
     The Articles of Incorporation provide that the Board of Directors of the
Company is divided into three classes as nearly equal in number as possible. The
directors of each class will serve a term of three years. As a result of the
classification of the Board of Directors, approximately one-third of the members
of the Board of Directors will be elected each year, and, two annual meetings
will be required for the Company's shareholders to change a majority of the
members constituting the Board of Directors.
 
                                       44
<PAGE>   49
 
  Nomination and Removal of Directors; Filling Vacancies
 
     The Company's Bylaws provide that nominations to the Board of Directors may
only be made by the Board of Directors, a nominating committee of the Board or
by any shareholder entitled to vote in elections of directors who complies with
certain notice procedures. In addition, the Articles of Incorporation provide
that (i) a director may be removed by the shareholders only upon the affirmative
vote of the holders of two-thirds of the voting power of all shares of capital
stock entitled to vote generally in the election of directors and (ii) vacancies
on the Board of Directors may be filled only by the Board of Directors. The
purpose of this provision is to prevent a majority shareholder from
circumventing the classified board system by removing directors and filling the
vacancies with new individuals selected by that shareholder. Accordingly, the
provision may have the effect of impeding efforts to gain control of the Board
by anyone who obtains a controlling interest in the Company's Common Stock.
 
  Amendment of Articles of Incorporation
 
     The Articles of Incorporation of the Company provide that amendments to the
Articles of Incorporation may be adopted only upon the affirmative vote of the
holders of at least two-thirds of the voting power of all shares of capital
stock of the Company entitled to vote thereon. However, if such amendment has
received the prior approval by an affirmative vote of a majority of
Disinterested Directors, as defined below, then the affirmative vote of the
holders of at least a majority of the voting power of all shares of capital
stock of the Company entitled to vote thereon, or such greater percentage
approval as required by North Carolina law, is sufficient to adopt such
amendment. A Disinterested Director is defined as any member of the Board of
Directors who is unaffiliated with, and not a nominee of, a Control Person, as
defined below, and was a member of the Board of Directors prior to the time a
Control Person became such, and any successor of a Disinterested Director who is
unaffiliated with, and not a nominee of, a Control Person, who is recommended to
succeed a Disinterested Director by a majority of Disinterested Directors then
on the Board of Directors. A Control Person is defined as any corporation,
person, group, or other entity, which together with its affiliates, prior to a
Business Combination, as defined below, beneficially owns 10% or more of the
shares of any class of equity or convertible securities of the Company, and any
affiliate of any such corporation, person, group, or other entity; provided,
however, any corporation, person, group or other entity which, together with its
affiliates, prior to January 1, 1994 beneficially owned 10% or more of the
shares of any class of equity or convertible securities of the Company, and any
affiliate of any such party is not considered to be a Control Person.
 
  Amendment of Bylaws
 
     Subject to certain restrictions described below, either the Board of
Directors or the shareholders of the Company may amend the Company's Bylaws. The
Board of Directors may amend the Bylaws and adopt new Bylaws except that: (i) a
bylaw adopted or amended by the shareholders may not be readopted, amended, or
repealed by the Board of Directors if neither the Articles of Incorporation nor
a bylaw adopted by the shareholders authorizes the Board of Directors to adopt,
amend, or repeal that particular bylaw or the Bylaws generally; (ii) a bylaw
that fixes a greater quorum or voting requirement for the Board of Directors may
not be adopted by the Board of Directors by a vote of less than a majority of
the directors then in office and may not itself be amended by a quorum or vote
of directors less than the quorum or vote therein prescribed or prescribed by a
bylaw adopted or amended by the shareholders; and (iii) if a bylaw fixing a
greater quorum or voting requirement for the Board of Directors is originally
adopted by the shareholders, it may be amended or repealed only by the
shareholders, unless the Bylaws permit amendment or repeal by the Board of
Directors. The shareholders of the Company generally may adopt, amend, or repeal
the Bylaws upon the affirmative vote of the holders of two-thirds of the voting
power of all shares of capital stock entitled to vote thereon.
 
  Supermajority Vote Requirement
 
     The Articles of Incorporation of the Company provide that, unless otherwise
more restrictively required by applicable law, any Business Combination, as
defined below, must be approved by a majority
 
                                       45
<PAGE>   50
 
of a quorum of the Board of Directors and must receive the level of shareholder
approval, if any, as follows: (i) to the extent shareholder approval is
otherwise required by law, by an affirmative vote of the shareholders holding at
least a majority of the shares of capital stock of the Company entitled to vote
thereon, provided that such Business Combination has been approved by an
affirmative vote of at least two-thirds of the full Board of Directors before
such Business Combination is submitted for approval to the shareholders or (ii)
by an affirmative vote of the shareholders holding at least two-thirds of the
shares of capital stock of the Company entitled to vote thereon provided that
such Business Combination has been approved by an affirmative vote of at least a
majority of a quorum of the Board of Directors (but less than two-thirds of the
full Board of Directors). In addition, if the Business Combination is approved
by the affirmative vote of the shareholders holding at least two-thirds of the
shares of Common Stock entitled to vote and by a majority of a quorum of the
Board of Directors but less than two-thirds of the full Board of Directors, the
Business Combination must grant to shareholders not voting to approve the
Business Combination certain "fair price" rights.
 
     The Company's Articles of Incorporation define a Business Combination as
(i) any merger or consolidation of the Company into any other corporation,
person, group, or other entity where the Company is not the surviving or
resulting entity; (ii) any merger or consolidation of the Company with or into
any Control Person or with any corporation, person, group or other entity where
the merger or consolidation is proposed by or on behalf of a Control Person;
(iii) any sale, lease, exchange, or other disposition of all or substantially
all of the assets of the Company; (iv) any sale, lease, exchange, or other
disposition of more than 10% of the total assets of the Company to a Control
Person; (v) the issuance of any securities of the Company to a Control Person;
(vi) the acquisition by the Company of any securities of a Control Person unless
such acquisition begins prior to the person becoming a Control Person or is an
attempt to prevent the Control Person from obtaining greater control of the
Company; (vii) the acquisition by the Company of all or substantially all of the
assets of any Control Person or any entity where the acquisition is proposed by
or on behalf of a Control Person; (viii) the adoption of any plan or proposal
for the liquidation or dissolution of the Company which is proposed by or on
behalf of a Control Person; (ix) any reclassification of securities or
recapitalization of the Company which has the effect of increasing the
proportionate share of the outstanding shares of any class of equity or
convertible securities of the Company which is beneficially owned or controlled
by a Control Person; (x) any of the above transactions which are between the
Company and any of its subsidiaries and which are proposed by or on behalf of
any Control Person; or (xi) any agreement, plan, contract, or other arrangement
providing for any of the above transactions.
 
     The requirement of a supermajority vote of shareholders to approve certain
business transactions, as described above, may discourage a change in control of
the Company by allowing shareholders holding less than a majority of the shares
of Common Stock to prevent a transaction favored by shareholders holding a
majority of such shares. Also, in some circumstances, the Board of Directors
could cause a two-thirds vote to be required to approve a transaction thereby
enabling management to retain control over the affairs of the Company and their
positions with the Company.
 
  Fair Price Provision
 
     The "fair price" provision of the Company's Articles of Incorporation
applies to Business Combinations which have not received the approval of
two-thirds of the full Board of Directors and only to shareholders who vote
against such Business Combinations and who elect to sell their shares to the
Company for cash at their fair price. This "fair price" provision requires that
the consideration for such shares be paid in cash by the Company and that the
price per share be at least equal to the greater of the following:
 
          (i) The highest price per share paid for the Company's Common Stock
     during the four years immediately preceding the Business Combination vote
     by any shareholder who beneficially owned five percent or more of the
     Company's Common Stock and who votes in favor of the Business Combination;
 
                                       46
<PAGE>   51
 
          (ii) The cash value of the highest price per share previously offered
     pursuant to a tender offer to the shareholders of the Company within the
     four years immediately preceding the Business Combination vote; or
 
          (iii) The highest price per share, including commissions and fees,
     paid by a Control Person in acquiring any of its holdings of the Company's
     Common Stock.
 
     The fair price provision is intended to prevent some of the potential
inequities of two-step takeover attempts by encouraging negotiations with the
Company. However, some shareholders may find the fair price provision
disadvantageous to the extent it discourages changes in control in which
shareholders might receive for at least some of their shares a substantial
premium above the market price at the time an acquisition transaction is made.
 
     The Company is not aware of any pending or threatened effort to acquire
control of the Company or to change management. The Board of Directors does not
presently intend to propose any additional anti-takeover provisions.
 
  Constituencies
 
     The Company's Articles of Incorporation expressly authorize the Board of
Directors of the Company, any committee of the Board of Directors, or any
individual director in determining what is in the best interest of the Company
and its shareholders, to consider, in addition to the long-term and short-term
interests of the shareholders, the social and economic effects of the matter to
be considered on the Company and its subsidiaries, their employees, clients,
creditors, and the communities in which the Company and its subsidiaries operate
or are located. When evaluating a business combination or a proposal by another
person to make a business combination or a tender offer or any other proposal
relating to a potential change in control of the Company, the Board of Directors
may consider such matters as the business and financial condition and earnings
prospects of the acquiring person, and the possible effect of such condition
upon the Company and its subsidiaries and the communities in which the Company
and its subsidiaries operate, the competence, experience, and integrity of the
acquiring person and its management and the prospects for successful conclusion
of the business combination, offer or proposal. The consideration of any of the
above factors is completely discretionary with the Company's Board of Directors.
The constituency provision of the Company's Articles of Incorporation may
discourage or make more difficult certain acquisition proposals or business
combinations and therefore, may adversely affect the ability of shareholders to
benefit from certain transactions opposed by the Company's Board of Directors.
 
  Special Meetings of Shareholders
 
     The Company's Bylaws provide that special meetings of shareholders may be
called only by the Board of Directors, the Chairman of the Board, the Chief
Executive Officer, the President or holders of 25% or more of the voting power
of the outstanding shares of the Company. As a result, this provision would
prevent shareholders owning less than 25% of the voting power of the outstanding
Common Stock from compelling shareholder consideration of any proposal (such as
a proposal for a Business Combination) over the opposition of the Company's
Board of Directors.
 
  Shareholder Proposals
 
     The Company's Bylaws provide that shareholders who desire to bring any
business before a meeting of shareholders must follow specified procedures
including advanced written notice to the Company. The shareholder proposal
provision may make it more difficult for shareholder proposals to be considered
at shareholder meetings.

  Transfer Agent and Registrar
 
     The Company's transfer agent and registrar for its Common Stock is First
Union National Bank of North Carolina, Charlotte, North Carolina.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Based upon 33,149,962 shares of Common Stock outstanding on December 31,
1996, upon completion of the Offerings, the Company will have 34,309,962 shares
of Common Stock issued and outstanding. Of these shares, 4,000,000 shares
offered in the Offerings, (plus an additional 600,000 if the Underwriters'
over-allotment options are exercised in full) and the 9,684,944 shares
registered and sold in the Company's two public offerings in 1994 and 1995,
respectively, issued in the acquisition of BRI and issued pursuant to the
Company's registration statements on Form S-8 under the Securities Act, will be
fully tradable without further registration or other restriction under the
Securities Act, excluding shares held by "affiliates" of the Company, as that
term is defined in Rule 144 promulgated under the Securities Act. In addition,
the Company has issued 1,076,771 shares pursuant to the exemption provided by
Regulation S promulgated under the Securities Act. Of the remaining 19,548,247
shares of Common Stock outstanding, 13,109,060 shares have been issued and
outstanding for more than three years or issued pursuant to Rule 701 under the
Securities Act and are therefore tradeable without restriction under the
Securities Act, except shares held by affiliates of the Company. See "Principal
and Selling Shareholders". The remaining 6,439,187 shares of Common Stock
outstanding are "restricted securities" within the meaning of Rule 144 (the
"Restricted Securities").
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are required to be aggregated) whose restricted securities have
been outstanding for at least two years, including a person who may be deemed an
"affiliate" of the Company, may only sell a number of shares within any
three-month period which does not exceed the greater of (i) one percent of the
then outstanding shares of the Company's Common Stock (approximately 343,099
shares after the Offerings) or (ii) the average weekly trading volume in the
Company's Common Stock in the four calendar weeks immediately preceding such
sale. Sales under Rule 144 are also subject to certain requirements as to the
manner of sale, notice and the availability of current public information about
the Company. A person who is not an affiliate of the issuer, has not been an
affiliate within 90 days prior to the sale and has owned the restricted
securities for at least three years is entitled to sell such shares under Rule
144(k) without regard to any of the limitations described above. The Securities
and Exchange Commission has proposed amendments to Rule 144 to reduce the
holding periods. If adopted such amendments would have a material effect on when
shares of Common Stock will become eligible for resale.
 
     The Company issued 9,214,239 shares in November 1996 in a share exchange
for all of the outstanding stock of Innovex (the "Exchange"). See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Overview". Such shares are the subject of a registration rights
agreement (the "Registration Rights Agreement"), a copy of which is filed as an
exhibit to the Registration Statement of which this Prospectus is a part,
pursuant to which 2,819,400 shares (plus an additional 600,000 shares if the
Underwriters' over-allotment options are exercised in full) are being offered in
the Offerings by former shareholders of Innovex. Accordingly, 6,394,839 of these
shares remain Restricted Securities. See "-- Registration Rights".
 
     As of December 31, 1996, options for the purchase of an aggregate of
2,404,334 shares were outstanding under the Company's stock option plans. Of
such amount, options for 1,264,505 shares of Common Stock are vested and
exercisable as of December 31, 1996. The Company has either registered such
shares on Form S-8 or such shares are eligible for resale under Rule 701 of the
Securities Act. Shares of Common Stock issued upon the exercise of options
granted under the Company's option plans or otherwise issued pursuant to the
Company's employee stock purchase plan will be available for sale in the public
market without restriction to the extent that they are held by persons who are
not affiliates of the Company and by affiliates, pursuant to Rule 144 (without
observance of the holding period requirement) or Rule 701.
 
                                       48
<PAGE>   53
 
     The Company has reserved 1,740,000 shares of Common Stock, subject to
adjustment in certain circumstances, for issuance upon conversion of the
Company's 4.25% Convertible Subordinated Notes due May 31, 2000 (the
"Convertible Notes"). Each $1,000 principal amount of the Convertible Notes is
convertible into Common Stock at any time at an initial conversion price of
$82.75 per share. The Company has filed a registration statement with respect to
$75,990,000 principal amount of the Convertible Notes, and the shares into which
such Convertible Notes are convertible, for resale by certain selling holders,
in accordance with a registration rights agreement relating thereto. Shares
transferred by selling holders pursuant to such registration statement will be
freely tradable; otherwise, shares of Common Stock issuable upon conversion of
the Convertible Notes will be Restricted Securities.
 
     The Selling Shareholders, executive officers and directors of the Company
have agreed pursuant to the Underwriting Agreement and other agreements that
during the period beginning from the date that is 30 days prior to the closings
of the Offerings and continuing to and including the date 90 days after the date
of this Prospectus, they will not offer, sell, contract to sell or otherwise
dispose of any securities of the Company (other than the shares of Common Stock
offered by the Selling Shareholders in the Offerings, or pursuant to employee
stock option plans existing, or on the conversion or exchange of convertible or
exchangeable securities outstanding, on the date of this Prospectus) which are
substantially similar to the shares of the Common Stock or which are convertible
into or exchangeable for securities which are substantially similar to the
shares of the Common Stock without the prior written consent of Goldman, Sachs &
Co. and, with respect to the executive officers and directors of the Company,
the Company. See "Underwriting".
 
     No prediction can be made as to the effect that future market sales of
Restricted Securities or the availability of such Restricted Securities for sale
will have on the market price of the Common Stock prevailing from time to time.
Sales of substantial amounts of Restricted Securities in the public market (or
the perception that such sales could occur) might adversely affect prevailing
market prices for the Common Stock.
 
REGISTRATION RIGHTS
 
     Pursuant to the Registration Rights Agreement, former shareholders of
Innovex are entitled to certain registration rights in connection with the
shares of Common Stock received in the Exchange (the "Exchange Shares"). In
furtherance of the Registration Rights Agreement, an aggregate of 2,819,400
shares of Common Stock (plus an additional 600,000 shares if the Underwriters'
over-allotment options are exercised in full) are being offered in the Offerings
by such shareholders. The terms of the Registration Rights Agreement require the
Company to file a shelf registration statement to register at least 5,000,000 of
the Exchange Shares by March 31, 1997 for offerings of Common Stock to be made
by former shareholders of Innovex in the aggregate amount of no more than
500,000 in any 90 day period. The Company must maintain the effectiveness of the
shelf registration statement for a period of up to three years subject to
periods of suspended use in certain events. The Registration Rights Agreement
provides additional demand registration rights in the event that 2,700,000 of
the Exchange Shares are not sold in this offering. Finally, the Registration
Rights Agreement provides that in the event the Company proposes to offer its
securities, either for its own account or for the account of a selling holder,
the former shareholders of Innovex shall be entitled to include the number of
Exchange Shares in such registration which is at least 20% of the amount
registered. In connection with the Registration Rights Agreement, Dennis B.
Gillings has agreed that for a period of two years from and after November 29,
1996, he will not sell or otherwise transfer shares other than (i) to a private
transferee which agrees to be bound by this restriction or (ii) to the public in
an amount during any three month period not to exceed one-half of one percent
( 1/2%) of the then outstanding shares of the Company's Common Stock in
"broker's transactions" as defined in Rule 144 (f) of the Securities Act.

</TABLE>
 
     Under the terms and conditions of the Underwriting Agreement, the U.S.
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
     The U.S. Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at such
price less a concession of $       per share. The U.S. Underwriters may allow,
and such dealers may reallow, a concession not in excess of $       per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and other selling terms may from time to
time be varied by the representatives.
 
     The Company and the Selling Shareholders have entered into an underwriting
agreement (the "International Underwriting Agreement") with the underwriters of
the international offering (the "International Underwriters") providing for the
concurrent offer and sale of 800,000 shares of Common Stock in an international
offering outside the United States. The offering price and aggregate
underwriting discounts and commissions per share for the two Offerings are
identical. The closing of the offering made hereby is a condition to the closing
of the International Offering, and vice versa. The representatives of the
International Underwriters are Goldman Sachs International, Morgan Stanley & Co.
International Limited, Smith Barney Inc. and William Blair & Company, L.L.C.
 
     Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two Offerings, each of the
U.S. Underwriters named herein has agreed that, as a part of the distribution of
the shares offered hereby and subject to certain exceptions, it will offer, sell
or deliver the shares of Common Stock, directly or indirectly, only in the
United States of America (including the States and the District of Columbia),
its territories, its possessions and other areas subject to its jurisdiction
(the "United States") and to U.S. persons, which term shall mean, for purposes
of this paragraph: (a) any individual who is a resident of the United States or
(b) any corporation, partnership or other entity organized in or under the laws
of the United States or any political subdivision thereof and whose office most
directly involved with the purchase is located in the United States. Each of the
International Underwriters has agreed pursuant to the Agreement Between that, as
a part of the distribution of the shares offered as a part of the International
Offering, and subject to certain exceptions, it will (i) not, directly or
indirectly, offer, sell or deliver shares of Common Stock (a) in the
 
                                       50
<PAGE>   55
 
United States or to any U.S. persons or (b) to any person who it believes
intends to reoffer, resell or deliver the shares in the United States or to any
U.S. persons, and (ii) cause any dealer to whom it may sell such shares at any
concession to agree to observe a similar restriction.
 
     Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall be
the initial public offering price, less an amount not greater than the selling
concession.
 
     Certain Selling Shareholders have granted the U.S. Underwriters an option
exercisable for 30 days after the date of this Prospectus to purchase up to an
aggregate of 480,000 additional shares of Common Stock solely to cover
over-allotments, if any. If the U.S. Underwriters exercise their over-allotment
option, the U.S. Underwriters have severally agreed, subject to certain
conditions, to purchase approximately the same percentage thereof that the
number of shares to be purchased by each of them, as shown in the foregoing
table, bears to the 3,200,000 shares of Common Stock offered in the U.S.
Offering. Certain Selling Shareholders have granted the International
Underwriters a similar option to purchase up to an aggregate of 120,000
additional shares of Common Stock.
 
     The Company and the Selling Shareholders have agreed that, during the
period beginning from the date that is 30 days prior to the closings of the
Offerings and continuing to and including the date 90 days after the date of the
Prospectus, they will not offer, sell, contract to sell or otherwise dispose of
any securities of the Company (other than pursuant to employee stock option
plans existing, or on the conversion or exchange of convertible or exchangeable
securities outstanding, on the date of this Prospectus) which are substantially
similar to the shares of the Common Stock or which are convertible into or
exchangeable for securities which are substantially similar to the shares of the
Common Stock without the prior written consent of Goldman, Sachs & Co., except
for the shares of Common Stock offered in connection with the concurrent U.S.
and International Offerings, and except, in the case of the Company, shares of
Common Stock issued by the Company as consideration for acquisitions of
businesses, properties or assets, provided, however, that each offeree,
purchaser or other transferee of any shares of Common Stock so issued in
connection with any such acquisition shall agree in writing for the benefit of
the Underwriters, in form and substance satisfactory to Goldman, Sachs & Co.,
that all such shares of Common Stock shall remain subject to restrictions
identical to those contained in this sentence.
 
     The Company and the Selling Shareholders have agreed to indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act of 1933.
 
     The Company and Innovex each engaged Goldman, Sachs & Co. ("Goldman Sachs")
to facilitate the share exchange between the Company and Innovex. Pursuant to
this arrangement, the Company paid to Goldman Sachs a fee of $6.5 million as
compensation for services relating to the share exchange and advisory services
in connection with a potential initial public offering of Innovex and reimbursed
Goldman Sachs for its reasonable costs and expenses incurred in connection with
its services. In addition, the Company agreed for Goldman Sachs to underwrite
shares offered in the Offerings.
 
     The Company retained Smith Barney Inc. ("Smith Barney") to provide a
fairness opinion to the Company in connection with the share exchange between
the Company and Innovex. The Company paid a financial advisory fee of $800,000
to Smith Barney, plus reimbursement of Smith Barney's reasonable costs and
expenses, in connection with such services. In addition, BRI engaged Smith
Barney to provide a fairness opinion in connection with the merger between the
Company and BRI; Smith Barney was paid a financial advisory fee by BRI of
$800,000, plus reimbursement of Smith Barney's reasonable costs and expenses, in
connection with such services.
 
     During and following the Offerings, the Underwriters may purchase and/or
sell Common Stock in the open market. These transactions may include
overallotment and stabilization transactions, "passive" market making (see
below) and purchases to cover syndicate short positions created in connection
with the Offerings. The Underwriters also may impose a penalty bid, whereby
selling concessions allowed to syndicate members or other broker-dealers in
respect of the Common Stock sold in the Offerings for their
 
                                       51
<PAGE>   56
 
account may be reclaimed by the syndicate if such shares are repurchased by the
syndicate in covering transactions. These activities may stabilize, maintain or
otherwise affect the market price of the Common Stock, which may be higher than
the price that might otherwise prevail in the open market. These transactions
may be effected on the Nasdaq National Market or otherwise, and these
activities, if commenced, may be discontinued at any time.
 
     Pursuant to regulations promulgated by the Commission, market makers in the
Common Stock who are Underwriters or prospective underwriters ("passive market
makers") may, subject to certain limitations, make bids for or purchases of
shares of Common Stock until (i) if the Commencement Date (as defined below) is
prior to March 4, 1997, the earlier of the time of commencement (the
"Commencement Date") of offers or sales of the Common Stock contemplated by this
Prospectus or the time, if any, at which a stabilizing bid for such shares is
made, or (ii) if the Commencement Date is on or after March 4, 1997, the time,
if any, at which a stabilizing bid for such shares is made. In general, if the
Commencement Date is prior to March 4, 1997 then, on and after the date two
business days prior to the Commencement Date, or, if the Commencement Date is on
or after March 4, 1997 then, prior to the time, if any, at which a stabilizing
bid for such shares is made (1) such market maker's net daily purchases of the
Common Stock may not exceed 30% of the market maker's average daily trading
volume in such stock for the two full consecutive calendar months immediately
preceding the filing date of the registration statement of which this Prospectus
forms a part, (2) such market maker may not effect transactions in, or display
bids for, the Common Stock at a price that exceeds the highest independent bid
for the Common Stock by persons who are not passive market makers and (3) bids
made by passive market makers must be identified as such.
 
                               VALIDITY OF SHARES
 
     The validity of the shares of Common Stock offered hereby will be passed

                           FORWARD LOOKING STATEMENTS
 
     Information set forth in this Prospectus under the captions "Summary",
"Risk Factors", "Use of Proceeds", "Management's Discussion and Analysis of
Financial Condition and Results of Operations", and "Business" contains various
"forward looking statements" within the meaning of Section 27A of the Securities
Act and Section 21E of the Exchange Act, which statements represent the
Company's judgment concerning the future and are subject to risks and
uncertainties that could cause the Company's actual operating results and
financial position to differ materially. Such forward looking statements can be
identified by the use of forward looking terminology, such as "may", "will",
"expect", "anticipate", "estimate", or "continue" or the negative thereof or
other variations thereof or comparable terminology.
 
     The Company cautions that any such forward looking statements are further
qualified by important factors that could cause the Company's actual operating

              REGULATED STAGES OF U.S. DRUG DEVELOPMENT ROUTINELY
                 OUTSOURCED TO A CONTRACT RESEARCH ORGANIZATION
 
PRE-CLINICAL RESEARCH (1 to 3.5 years)
 
     In vitro ("test tube") and animal studies to establish the relative
toxicity of the drug over a wide range of doses and to detect any potential to
cause birth defects or cancer. If results warrant continuing development of the
drug, the manufacturer will file for an IND (Investigational New Drug), with the
FDA for permission to begin testing in humans.
 
CLINICAL TRIALS(3.5 to 6 years)
 
     -PHASE I (6 mos. to 1 year) Basic safety and pharmacology testing in 20 to
80 human subjects -- usually healthy volunteers -- includes pharmacokinetic and
pharmacodynamic studies to determine how the drug works, how it is affected by
other drugs, where it goes in the body, how long it remains active, and how it
is broken down and eliminated from the body.
 
     -PHASE II (1 to 2 years) Basic efficacy (effectiveness) and dose-range
testing in 100 to 200 afflicted volunteers to help determine the best effective
dose, confirm that the drug works as expected, and provide additional safety
data.
 
     -PHASE IIIA (2 to 3 years) Efficacy/safety studies in hundreds to thousands
of patients at many investigational sites (hospitals and clinics) -- can be
placebo-controlled trials, in which the new drug is compared with a "sugar
pill", or studies comparing the new drug with one or more drugs with established
safety and efficacy profiles in the same therapeutic category.
 
TIND (May span late Phase II, Phase III, and FDA review)
 
     When results from Phase II or Phase III show special promise in the
treatment of a serious condition for which existing therapeutic options are
limited or of minimal value, the FDA may allow the company to make the new drug
available to a larger number of patients through the regulated mechanism of a
TIND (Treatment Investigational New Drug). Although less scientifically rigorous
than a controlled clinical trial, a TIND may enroll and collect a substantial
amount of data from tens of thousands of patients.
 
NDA PREPARATION AND SUBMISSION (As soon as possible after completion of Phase
III trials)
 
     Upon completion of Phase III trials, the manufacturer assembles the
statistically analyzed data from all phases of development into a single large
document, the New Drug Application (NDA), which today comprises, on average,
roughly 100,000 pages.
 
     -PHASE IIIB (1 to 2 years) Studies conducted after NDA submission but
before regulatory approval is issued, often an extension of Phase IIIa studies
with an even broader patient population.
 
FDA REVIEW AND APPROVAL (2.5 years)
 
     Careful scrutiny of data from all phases of development (including a TIND)
to confirm that the company has complied with regulations and that the drug is
safe and effective for the specific use (or "indication") under study.
 
POST-MARKETING SURVEILLANCE AND PHASE IV STUDIES (For the life of the brand)
 
     Federal regulation requires the company to collect and periodically report
to the FDA additional safety and efficacy data on the drug for as long as the
company markets the drug (post-marketing surveillance). If the drug is marketed
outside the United States, these reports must include data from all countries in
which the drug is sold. Additional studies (Phase IV) may be undertaken after
initial approval to find new uses for the drug, to test new dosage formulations,
or to confirm selected non-clinical benefits, e.g., increased cost-effectiveness
or improved quality of life.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders of
Quintiles Transnational Corp.
 
     We have audited the accompanying consolidated balance sheets of Quintiles
Transnational Corp. and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of income, shareholders' equity, and cash flows
for each of the three years in the period ended December 31, 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 did not audit the 1995 and 1994 consolidated financial statements
of BRI International, Inc. and Innovex Limited, each of which was combined with
the Company in 1996 in transactions accounted for as poolings of interests.
Total assets of the two businesses represent 39% of the consolidated assets for
1995, and total revenues constituted 42% and 43% of consolidated revenue for
1995 and 1994, respectively. Those statements were audited by other auditors
whose reports have been provided to us, and our opinion, insofar as it relates
to amounts included for BRI International, Inc. and Innovex Limited for 1995 and
1994, is based solely on the reports of the other auditors.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the reports of other auditors provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the reports of other auditors, the
financial statements referred to above present fairly, in all material respects,
the consolidated financial position of Quintiles Transnational Corp. and
subsidiaries at December 31, 1996 and 1995, and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1996, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The Company
 
     The Company is a leading provider of comprehensive contract research and
sales and marketing services to the worldwide pharmaceutical, biotechnology and
medical device industries. Additionally, the Company supports the developing
information needs of the broader healthcare industry by providing health
economics and healthcare policy consulting and disease and health information
management services.
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts and
operations of the Company and its subsidiaries. All material intercompany
accounts and transactions have been eliminated in consolidation.
 
     Prior to the Company's November 29, 1996 share exchange with Innovex,
Innovex had a fiscal year end of March 31 and the Company had (and continues to
have) a fiscal year end of December 31. As a result, the pooled data presented
for 1992 through 1995 include Innovex's March 31 fiscal year data in combination
with the Company's December 31 fiscal year data. In connection with the share
exchange, Innovex changed its fiscal year end to December 31. Accordingly, the
pooled data presented for 1996 include both Innovex's and the Company's data on
a December 31 year end basis. Because of the difference between Innovex's fiscal
year end in 1995 compared with 1996, Innovex's quarter ended March 31, 1996 data
are included in the Company's pooled data for both 1995 and 1996.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Foreign Currencies
 
     Assets and liabilities recorded in foreign currencies on the books of
foreign subsidiaries are translated at the exchange rate on the balance sheet
date. Revenues, costs and expenses are recorded at average rates of exchange
during the year. Translation adjustments resulting from this process are charged
or credited to equity. Gains and losses on foreign currency transactions are
included in other income (expense).
 
  Revenue Recognition
 
     The Company recognizes net revenue from its contracts on a
percentage-of-completion or per diem basis as work is performed. The Company's
exposure to credit loss is equal to the outstanding accounts receivable and
unbilled services balance. Although the Company does not require collateral for
unpaid balances, credit losses have consistently been within management's
expectations. Certain contracts contain provisions for price redetermination for
cost overruns. Such redetermined amounts are included in service revenue when
realization is assured and the amounts can be reasonably determined. 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 ultimate loss is charged against
income. One client accounted for 11.9% of consolidated net revenue in 1996.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Unbilled Services and Unearned Income
 
     In general, prerequisites for billings are established by contractual
provisions including predetermined payment schedules, the achievement of
contract milestones or submission of appropriate billing detail. Unbilled
services arise when services have been rendered but clients have not been
billed. Similarly, unearned income represents prebillings for services that have
not yet been rendered.
 
  Reimbursed Costs
 
     Investigator payments are recognized as expense based upon patient
enrollment over the life of the contract. Investigator payments are made based
on predetermined contractual arrangements, which may differ from the recognition
of the expense. Payments to investigators in excess of the expense recognized
are classified as prepaid expenses, and recognized expenses in excess of amounts
paid are classified as accrued expenses.
 
  Cash Equivalents and Investments
 
     The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. The Company has
excluded from cash and cash equivalents in the accompanying balance sheets cash
held for clients for investigator payments in the amount of $4.6 million and
$3.0 million at December 31, 1996 and 1995, respectively, that pursuant to
agreements with these clients, remains the property of the clients.
 
     The Company's investments in debt and equity securities are classified as
held-to-maturity and available for sale. Investments classified as
held-to-maturity are recorded at amortized cost. Investments classified as
available for sale are measured at market value and net unrealized gains and
losses are recorded as a separate component of stockholders' equity until
realized. Any gains or losses on sales of investments are computed by specific
identification.
 
  Property and Equipment
 
     Property and equipment are carried at historical cost and are depreciated
using the straight-line method over the shorter of the asset's estimated useful
life or the lease term ranging from three to 50 years.
 
  Intangible Assets
 
     Intangibles consist principally of the excess cost over the fair value of
net assets acquired ("goodwill") and are being amortized on a straight-line
basis over periods not exceeding 40 years. Accumulated amortization totaled
$10.5 million and $5.2 million at December 31, 1996 and 1995, respectively.
 
     The carrying values of intangible assets are reviewed if the facts and
circumstances suggest impairment. If this review indicates that carrying values
will not be recoverable, as determined based on undiscounted cash flows over the
remaining amortization period, the Company would reduce carrying values by the
estimated shortfall of cash flows.
 
  Long-Lived Assets
 
     The Company adopted Financial Accounting Standard Board ("FASB") Statement
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of" ("Statement 121") in the first quarter of 1996. The
adoption of Statement 121 had no material effect on the financial statements in
1996.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Net Income Per Share
 
     Net income per share has been computed using the weighted average number of
common shares (including the common shares held by the Employee Stock Ownership
Plan) and common share equivalents outstanding during each period. Common
equivalent shares are excluded from the computation in periods in which they
have an anti-dilutive effect. All share and per share data in the financial
statements and notes thereto have been retroactively adjusted to give effect to
the two-for-one stock split in November 1995 and to the pooling of interests
combinations with BRI and Innovex (see Note 3). For all periods presented, the
difference between primary and fully diluted net income per common share is not
significant.
 
  Income Taxes
 
     Income tax expense includes U.S. and international income taxes. Certain
items of income and expense are not reported in tax returns and financial
statements in the same year. The tax effects of these differences are reported
as deferred income taxes. Tax credits are accounted for as a reduction of tax
expense in the year in which the credits reduce taxes payable.
 
  Research and Development Costs
 
     Research and development costs relating principally to new software
applications and computer technology are charged to expense as incurred. These
expenses totaled $2.3 million, $1.9 million and $1.7 million in 1996, 1995 and
1994, respectively.
 
  Foreign Currency Hedging
 
     The Company uses foreign exchange contracts and options to hedge the risk
of changes in foreign currency exchange rates associated with contracts in which
the expenses for providing services are incurred in one currency and paid for by
the client in another currency. The Company recognizes changes in value in
income only when contracts are settled or options are exercised. At December 31,
1996, the Company had forward contracts maturing on December 29, 1999. As of
December 31, 1996, the Company has committed to purchasing approximately
L600,000 (approximately $852,000) under such contracts. The Company is obligated
to purchase up to an additional L8.6 million through December 28, 1999 in
varying amounts as the daily dollar-to-pound exchange rate ranges between 1.5499
and 1.6800.
 
2. SHAREHOLDERS' EQUITY
 
     On November 26, 1996, the Company's shareholders approved an increase in
the number of authorized shares of the Common Stock from 50,000,000 to
200,000,000.
 
     On July 25, 1996, the Board of Directors authorized an employee stock
purchase plan for all eligible employees effective October 1, 1996. Under the
plan, shares of the Company's Common Stock may be purchased at three month
intervals at 85% of the lower of the fair market value on the first or the last
day of each three month period. Employees may purchase shares having a value not
exceeding the lesser of 15% of their gross compensation during an offering
period or $25,000. During 1996, employees purchased 4,788 shares at $56.3125 per
share. At December 31, 1996, 95,212 shares were reserved for future issuance.
 
     On April 3, 1996, in anticipation of a planned initial public offering,
Innovex was recapitalized by the purchase of the entire issued share capital of
Innovex Holdings Limited (the former holding company of the Innovex Group) from
its shareholders in exchange for a combination of newly issued Ordinary Shares,
Cumulative Participating Preferred Ordinary Shares (the "Preferred Shares"),

     Undistributed earnings of the Company's foreign subsidiaries amounted to
approximately $19 million at December 31, 1996. Those earnings are considered to
be indefinitely reinvested, and accordingly, no U.S. federal and state income
taxes have been provided thereon. Upon distribution of those earnings in the
form of dividends or otherwise, the Company would be subject to both U.S. income
taxes (subject to an adjustment for foreign tax credits) and withholding taxes
payable to the various countries.

     The U.K. subsidiaries qualify for Scientific Research Allowances (SRAs) for
100% of capital expenditures on certain assets under the Inland Revenue Service
guidelines. For 1996, 1995 and 1994, these allowances were $11 million, $6
million and $3 million, respectively, which helped to generate net operating
loss carryforwards of $3 million to be used to offset taxable income in that
country. Assuming the U.K. subsidiaries continue to invest in qualified capital
expenditures at an adequate level, the portion of the deferred tax liability
relating to the U.K. subsidiaries may be deferred indefinitely. Quintiles
Transnational has state net operating loss carryforwards of approximately $10
million which begin to expire in 2001. Innovex has German net operating loss
carryforwards that do not expire of $10 million to be used to offset taxable
income in that country. In addition, Innovex, Inc. has U.S. net operating loss
carryforwards of approximately $5 million which will expire beginning 2005.
 
10. EMPLOYEE BENEFIT PLANS
 
     The Company has numerous employee benefit plans for which contributions are
discretionary. Plans exist in the United States, Germany, the United Kingdom,
Ireland, Belgium, France, and Australia which cover substantially all eligible
employees in those countries. Plans include Approved Profit Sharing Schemes in
Great Britain and Ireland which are funded with Company stock, a defined
contribution plan funded by Company stock in Belgium and Australia, defined
contribution plans in Great Britain, a profit sharing scheme in France, and
defined benefit plans in Great Britain and Germany. The defined benefit plan in
Germany is an unfunded plan which is provided for in the balance sheet.
 
     The Company has two leveraged Employee Stock Ownership Plans ("ESOPs")
which provide benefits to eligible employees. Contributions and related
compensation expenses for these plans totaled $585,000, $734,000, and $174,000
in 1996, 1995 and 1994, respectively. Interest paid by the Company on the ESOP
loan was approximately $130,000, $157,000, and $179,000 for 1996, 1995, and
1994, respectively. Shares allocated to participants totaled 938,000 at December
31, 1996. Unallocated shares totaled 178,000 as of December 31, 1996 with a fair
value of $11,820,000.
 
     The Company has two employee savings and investment plans (401(k) Plans)
available to all eligible employees meeting certain specified criteria. The
Company matches employee deferrals at varying percentages, set at the discretion
of the Board of Directors. For the years ended December 31, 1996, 1995 and 1994,
the Company expensed $539,000, $177,000 and $0, respectively as matching
contributions.
 
     On July 25, 1996, the Company's Board of Directors adopted the Quintiles
Transnational Corp. Employee Stock Purchase Plan (the "Purchase Plan") which is
intended to provide eligible employees an opportunity to acquire the Company's
Common Stock. Participating employees have the option to purchase shares at 85%
of the lower of the closing price per share of Common Stock on the first or last
day of the calendar quarter. The Purchase Plan is intended to qualify as an
"employee stock purchase

plan" under Section 423 of the Internal Revenue Code of 1986, as amended. The
Board of Directors has reserved 100,000 shares of Common Stock for issuance
under the Purchase Plan. As of December 31, 1996, 4,788 shares were purchased
under the Purchase Plan at a cost of $56.3125 per share.
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation" ("Statement 123"),
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB 25, because the exercise price of the
Company's employee stock options equals the market price of the underlying stock
on the date of grant, no compensation expense is recognized.
 
     The Company has stock option plans to provide incentives to eligible
employees, officers, and directors in the form of incentive stock options,
non-qualified stock options, stock appreciation rights, and restricted stock.
The Board of Directors determines the option price (not to be less than fair
market value of incentive options) at the date of grant. The majority of
options, granted under the Executive Compensation Plan, typically vest twenty
five percent per year over four years, and expire ten years from the date of
grant. Other options including options granted and exchanged as a result of
acquisitions have various vesting schedules and expiration periods.
 
     Information with respect to the consolidated option plans is as follows:

     Pro forma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of that
Statement. The fair value for these options was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions for 1996 and 1995: risk-free interest rate of 6%; dividend yields of
0%; volatility factors of the expected market price of the Company's Common
Stock of 0.4; and an average expected life of the option of one year from the
date of vesting.

     The Black-Scholes valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are
transferable. In addition, the option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options and changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The grant date
Black-Scholes value of the options for 1996 was $10,900,000. Of this amount,
$7,145,000 relates to options issued and exchanged to employees of acquired
companies. The remaining $3,755,000 relates to Quintiles options, representing
7% of operating income. The Black-Scholes value of the options for 1995 was
$739,000 which includes $85,000 relating to acquired companies.

                    CERTAIN U.S. FEDERAL TAX CONSIDERATIONS
                      FOR NON-U.S. HOLDERS OF COMMON STOCK
 
     The following is a summary of certain United States federal income and
estate tax considerations relating to the purchase, ownership and disposition of
Common Stock, but does not purport to be a complete analysis of all the
potential tax considerations relating thereto. This summary is based on
statutes, regulations, rulings and decisions now in effect (or, in the case of
certain United States Treasury Regulations ("Treasury Regulations"), now in
proposed form), all of which are subject to change. INVESTORS CONSIDERING THE
PURCHASE OF COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO
THE APPLICATION OF THE UNITED STATES FEDERAL INCOME AND ESTATE TAX LAWS TO THEIR
PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF
ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX
TREATY.
 
NON-UNITED STATES HOLDERS
 
     As used herein, the term "Non-United States Holder" means any beneficial
owner of Common Stock that for United States federal income tax purposes is not
any of the following: (i) a citizen or resident, as specifically defined for
United States federal income and estate tax purposes, of the United States, (ii)
a corporation, partnership, or an entity treated as a corporation or partnership
for United States federal income tax purposes created or organized in the United
States or under the laws of the United States or any state, or (iii) an estate
or trust the income of which is included in gross income for United States
federal income tax purposes regardless of its source.
 
DIVIDENDS
 
     Dividends paid to a Non-United States Holder will generally be subject to
United States federal withholding tax at a 30% rate (or lower rate provided
under any applicable income tax treaty). However, dividends effectively
connected with a trade or business carried on by the Non-United States Holder
within the United States will not be subject to withholding if the Non-United
States Holder delivers IRS Form 4224 to the payor. Instead, except to the extent
that an applicable tax treaty otherwise provides, such dividends will generally
be subject to United States federal income tax on a net income basis at regular
graduated rates. Any such dividends paid to a Non-United States Holder that is a
foreign corporation may also be subject to United States branch profits tax at a
30% rate or such lower rate as may be specified by an applicable income tax
treaty.
 
     Under current Treasury Regulations, dividends paid to an address in a
foreign country are presumed to be paid to a resident of that country (unless
the payor has knowledge to the contrary) for purposes of the withholding
discussed above and, under the current interpretation of the applicable Treasury
Regulations, for purposes of determining the applicability of a tax treaty rate.
Under proposed Treasury Regulations issued in 1996 (the "Proposed Regulations"),
a Non-United States Holder of Common Stock who wishes to claim the benefit of an
applicable treaty rate would be required to satisfy certain certification
requirements. In addition, in the case of Common Stock held by foreign
partnerships, the Proposed Regulations generally would require that (x) the
certification requirement be applied to the partners of the partnership and (y)
the partnership provide certain information, including a United States taxpayer
identification number. The Proposed Regulations also provide look-through rules
for certain tiered partnerships. It is not clear whether, when or in what form
the Proposed Regulations will be adopted as final regulations.
 
SALE OF COMMON STOCK
 
     Generally, a Non-United States Holder will not be subject to U.S. federal
income tax on any gain realized upon the disposition of such holder's shares of
Common Stock unless (i) the gain is effectively connected with a trade or
business carried on by the Non-United States Holder within the United States;
(ii) the Non-United States Holder is an individual who holds the shares of
Common Stock as a capital
 
                                       49
<PAGE>   82
 
                 [ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS]
 
asset and is present in the United States for 183 days or more in the taxable
year of the disposition and either the Non-United States Holder has a "tax home"
in the United States or the gain from the disposition is attributable to an
office or fixed place of business maintained by such Non-United States Holder in
the United States; (iii) the Non-United States Holder is subject to tax pursuant
to the provisions of United States tax law applicable to certain United States
expatriates; or (iv) the Company is or has been during certain periods a "U.S.
real property holding corporation" for United States federal income tax purposes
(which the Company does not believe that it is or is likely to become) and,
assuming that the Common Stock is deemed for tax purposes to be "regularly
traded on an established securities market", the Non-United States Holder held,
at any time during the five-year period ending on the date of disposition (or
such shorter period that such shares were held), directly or indirectly, more
than five percent of the Common Stock.
 
DEATH OF A NON-UNITED STATES HOLDER
 
     Common Stock actually or beneficially held by a Non-United States Holder at
the time of his or her death (or previously transferred subject to certain
retained rights or powers) will be subject to United States federal estate tax
unless otherwise provided by an applicable estate tax treaty.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING TAX
 
     Current U.S. federal income tax law requires the reporting of certain
information by the payors of dividends to certain non-corporate persons and
imposes a withholding tax at the rate of 31% on certain payments to persons who
fail to furnish information required under the information reporting rules.
Under current law, if paid to an address outside the United States, dividends on
Common Stock held by a Non-United States Holder will not be subject to the
information reporting and backup withholding requirements described in this
section, provided the payor does not have definite knowledge that the payee is a
United States person. However, under the Proposed Regulations, dividend payments
generally will be subject to information reporting and backup withholding unless
applicable certification requirements are satisfied. See the discussion above
with respect to the rules applicable to foreign partnerships under the Proposed
Regulations.
 
     Information reporting requirements and backup withholding tax will not
apply to any payment of the proceeds of the sale of Common Stock effected
outside the United States by a foreign office of a "broker" (as defined in
applicable Treasury Regulations), unless such broker (i) is a United States
person, (ii) derives 50% or more of its gross income for certain periods from
the conduct of a trade or business in the United States or (iii) is a controlled
foreign corporation as to the United States. Payment of the proceeds of any such
sale effected outside the United States by a foreign office of any broker that
is described in clause (i), (ii) or (iii) of the preceding sentence will not be
subject to backup withholding tax, but will be subject to information reporting
requirements unless such broker has documentary evidence in its records that the
beneficial owner is a Non-United States Holder and certain other conditions are
met, or the beneficial owner otherwise establishes an exemption. Payment of the
proceeds of any such sale to or through the United States office of a broker is
subject to information reporting and backup withholding requirements, unless (i)
either (a) the beneficial owner of the Common Stock provides a Form W-8 (or a
suitable substitute form) signed under penalties of perjury that includes its
name and address and certifies as to its non-United States status in compliance
with applicable law and regulations, or (b) a securities clearing organization,
bank or other financial institution that holds customers' securities in the
ordinary course of its trade or business holds the Common Stock and provides a
statement to the Company or its agent under penalties of perjury in which it
certifies that such a Form W-8 (or a suitable substitute) has been received by
it from the Non-United States Holder or qualifying intermediary and furnishes
the Company or its agent a copy thereof or (ii) the beneficial owner of the
Common Stock otherwise establishes an exemption.
 
     These backup withholding and information reporting rules are under review
by the Department of the Treasury and their application to the Common Stock
could be changed prospectively by future regulations.

</TABLE>
 
     Under the terms and conditions of the Underwriting Agreement, the
International Underwriters are committed to take and pay for all of the shares
offered hereby, if any are taken.
 
     The International Underwriters propose to offer the shares of Common Stock
in part directly to the public at the initial public offering price set forth on
the cover page of this Prospectus and in part to certain securities dealers at
such price less a concession of $          per share. The International
Underwriters may allow, and such dealers may reallow, a concession not in excess
of $          per share to certain brokers and dealers. After the shares of
Common Stock are released for sale to the public, the offering price and other
selling terms may from time to time be varied by the representatives.
 
     The Company and the Selling Shareholders have entered into an underwriting
agreement (the "Underwriting Agreement") with the underwriters of the U. S.
offering (the "U.S. Underwriters") providing for the concurrent offer and sale
of 3,200,000 shares of Common Stock in the United States. The offering price and
aggregate underwriting discounts and commissions per share for the two Offerings
are identical. The closing of the offering made hereby is a condition to the
closing of the U. S. Offering, and vice versa. The representatives of the U. S.
Underwriters are Goldman, Sachs & Co., Morgan Stanley & Co. Incorporated, Smith
Barney Inc. and William Blair & Company, L.L.C.
 
     Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two Offerings, each of the
U.S. Underwriters has agreed that, as a part of the distribution of the shares
offered hereby and subject to certain exceptions, it will offer, sell or deliver
the shares of Common Stock, directly or indirectly, only in the United States of
America (including the States and the District of Columbia), its territories,
its possessions and other areas subject to its jurisdiction (the "United
States") and to U.S. persons, which term shall mean, for purposes of this
paragraph: (a) any individual who is a resident of the United States or (b) any
corporation, partnership or other entity organized in or under the laws of the
United States or any political subdivision thereof and whose office most
directly involved with the purchase is located in the United States. Each of the
International Underwriters has agreed pursuant to the Agreement Between that, as
a part of the distribution of the shares offered as a part of the International
Offering, and subject to certain exceptions, it will (i) not, directly or
indirectly, offer, sell or deliver shares of Common Stock (a) in the United
States or to any U.S. persons or (b) to any person who it believes intends to
reoffer, resell or deliver the shares
 
                                       51
<PAGE>   84
 
                 [ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS]
 
in the United States or to any U.S. persons, and (ii) cause any dealer to whom
it may sell such shares at any concession to agree to observe a similar
restriction.
 
     Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall be
the initial public offering price, less an amount not greater than the selling
concession.
 
     Certain Selling Shareholders have granted the International Underwriters an
option exercisable for 30 days after the date of this Prospectus to purchase up
to an aggregate of 120,000 additional shares of Common Stock solely to cover
over-allotments, if any. If the International Underwriters exercise their over-
allotment option, the International Underwriters have severally agreed, subject
to certain conditions, to purchase approximately the same percentage thereof
that the number of shares to be purchased by each of them, as shown in the
foregoing table, bears to the 800,000 shares of Common Stock offered in the
International Offering. Certain selling shareholders have granted the U.S.
Underwriters a similar option to purchase up to an aggregate of 480,000
additional shares of Common Stock.
 
     The Company and the Selling Shareholders have agreed that, during the
period beginning from the date that in 30 days prior to the closing of the
Offerings and continuing to and including the date 90 days after the date of the
Prospectus, they will not offer, sell, contract to sell or otherwise dispose of
any securities of the Company (other than pursuant to employee stock option
plans existing, or on the conversion or exchange of convertible or exchangeable
securities outstanding, on the date of this Prospectus) which are substantially
similar to the shares of the Common Stock or which are convertible into or
exchangeable for securities which are substantially similar to the shares of the
Common Stock without the prior written consent of Goldman Sachs International,
except for the shares of Common Stock offered in connection with the concurrent
U.S. and International Offerings, and except, in the case of the Company, shares
of Common Stock issued by the Company as consideration for acquisitions of
businesses, properties or assets, provided, however, that each offeree,
purchaser or other transferee of any shares of Common Stock so issued in
connection with any such acquisition shall agree in writing for the benefit of
the Underwriters, in form and substance satisfactory to Goldman Sachs
International, that all such shares of Common Stock shall remain subject to
restrictions identical to those contained in this sentence.
 
     Each International Underwriter has also agreed that (a) it has not offered
or sold and prior to the date six months after the date of issue of the shares
of Common Stock will not offer or sell any shares of Common Stock to persons in
the U.K. except to persons whose ordinary activities involve them in acquiring,
holding, managing or disposing of investments (as principal or agent) for the
purposes of their businesses or otherwise in circumstances which have not
resulted and will not result in an offer to the public in the U.K. within the
meaning of the Public Offers of Securities Regulations 1995, (b) it has
complied, and will comply with, all applicable provisions of the Financial
Services Act of 1986 of Great Britain with respect to anything done by it in
relation to the shares of Common Stock in, from or otherwise involving the U.K.,
and (c) it has only issued or passed on and will only issue or pass on in the
U.K. any document received by it in connection with the issuance of the shares
of Common Stock to a person who is of a kind described in Article 11(3) of the
Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996
of Great Britain or is a person to whom the document may otherwise lawfully be
issued or passed on.
 
     Buyers of shares of Common Stock offered hereby may be required to pay
stamp taxes and other charges in accordance with the laws and practice of the
country of purchase in addition to the initial public offering price.
 
     The Company and the Selling Shareholders have agreed to indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act of 1933.
 
     The Company and Innovex each engaged Goldman, Sachs & Co. ("Goldman Sachs")
to facilitate the share exchange between the Company and Innovex. Pursuant to
this arrangement, the Company
 
                                       52
<PAGE>   85
 
                 [ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS]
 
paid to Goldman Sachs a fee of $6.5 million as compensation for services
relating to the share exchange and advisory services in connection with a
potential initial public offering of Innovex and reimbursed Goldman Sachs for
its reasonable costs and expenses incurred in connection with its services. In
addition, the Company agreed for Goldman Sachs to underwrite shares offered in
the Offerings.
 
     The Company retained Smith Barney Inc. ("Smith Barney") to provide a
fairness opinion to the Company in connection with the share exchange between
the Company and Innovex. The Company paid a financial advisory fee of $800,000
to Smith Barney, plus reimbursement of Smith Barney's reasonable costs and
expenses, in connection with such services. In addition, BRI engaged Smith
Barney to provide a fairness opinion in connection with the merger between the
Company and BRI; Smith Barney was paid a financial advisory fee by BRI of
$800,000, plus reimbursement of Smith Barney's reasonable costs and expenses, in
connection with such services.
 
     During and following the Offerings, the Underwriters may purchase and/or
sell Common Stock in the open market. These transactions may include
overallotment and stabilization transactions, "passive" market making (see
below) and purchases to cover syndicate short positions created in connection
with the Offerings. The Underwriters also may impose a penalty bid, whereby
selling concessions allowed to syndicate members or other broker-dealers in
respect of the Common Stock sold in the Offerings for their account may be
reclaimed by the syndicate if such shares are repurchased by the syndicate in
covering transactions. These activities may stabilize, maintain or otherwise
affect the market price of the Common Stock, which may be higher than the price
that might otherwise prevail in the open market. These transactions may be
effected on the Nasdaq National Market or otherwise, and these activities, if
commenced, may be discontinued at any time.
 
     Pursuant to regulations promulgated by the Commission, market makers in the
Common Stock who are Underwriters or prospective underwriters ("passive market
makers") may, subject to certain limitations, make bids for or purchases of
shares of Common Stock until (i) if the Commencement Date (as defined below) is

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Sections 55-8-50 through 55-8-58 of the North Carolina Business Corporation
Act permit a corporation to indemnify its directors, officers, employees or
agents under either or both a statutory or nonstatutory scheme of
indemnification scheme of indemnification. Under the statutory scheme, a
corporation may, with certain exceptions, indemnify a director, officer,
employee or agent of the corporation who was, is, or is threatened to be made, a
party to any threatened, pending or completed legal action, suit or proceeding,
whether civil, criminal, administrative, or investigative, because of the fact
that such person was a director, officer, agent or employee of the corporation,
or is or was serving at the request of such corporation as a director, officer,
employee or agent of another corporation or enterprise. This indemnity may
include the obligation to pay any judgment, settlement, penalty, fine (including
an excise tax assessed with respect to an employee benefit plan) and reasonable
expenses incurred in connection with a proceeding (including counsel fees), but
no such indemnification may be granted unless such director, officer, agent or
employee (i) conducted himself in good faith, (ii) reasonably believed (1) that
any action taken in his official capacity with the corporation was in the best
interest of the corporation or (2) that in all other cases his conduct at least
was not opposed to the corporation's best interest, and (iii) in the case of any
criminal proceeding, had no reasonable cause to believe his conduct was
unlawful. Whether a director has met the requisite standard of conduct for the
type of indemnification set forth above is determined by the board of directors,
a committee of directors, special legal counsel or the shareholders in
accordance with Section 55-8-55. A corporation may not indemnify a director
under the statutory scheme in connection with a proceeding by or in the right of
the corporation in which the director was adjudged liable to the corporation or
in connection with a proceeding in which a director was adjudged liable on the
basis of having received an improper personal benefit.
 
     In addition to, and separate and apart from the indemnification described
above under the statutory scheme, Section 55-8-57 of the North Carolina Business
Corporation Act permits a corporation to indemnify or agree to indemnify any of
its directors, officers, employees or agents against liability and expenses
(including attorney's fees) in any proceeding (including proceedings brought by
or on behalf of the corporation) arising out of their status as such or their
activities that were, at the time taken, known
 
                                      II-1
<PAGE>   89
 
or believed by the person to be clearly in conflict with the best interests of
the corporation. The Company's bylaws provide for indemnification to the fullest
extent permitted under the North Carolina Business Corporation Act, provided,
however, that the Company will indemnify any person seeking indemnification in
connection with a proceeding initiated by such person only if such proceeding
was authorized by the Board of Directors of the Company. Accordingly, the
Company may indemnify its directors, officers and employees in accordance with
either the statutory or the non-statutory standard.
 
     Sections 55-8-52 and 55-8-56 of the North Carolina Business Corporation Act
require a corporation, unless its articles of incorporation provide otherwise,
to indemnify a director or officer who has been wholly successful, on the merits
or otherwise, in the defense of any proceeding to which such director or officer
was a party. Unless prohibited by the articles of incorporation, a director or
officer also may make application and obtain court-ordered indemnification if
the court determines that such director or officer is fairly and reasonably
entitled to such indemnification as provided in Sections 55-8-54 and 55-8-56.
 
     Finally, Section 55-8-57 of the North Carolina Business Corporation Act
provides that a corporation may purchase and maintain insurance on behalf of an
individual who is or was a director, officer, employee or agent of the
corporation against certain liabilities incurred by such persons, whether or not
the corporation is otherwise authorized by the North Carolina Business
Corporation Act to indemnify such party. The Company's directors and officers
are currently covered under directors' and officers' insurance policies
maintained by the Company.
 
     As permitted by North Carolina law, Article XI of the Company's Articles of
Incorporation limits the personal liability of directors for monetary damages
for breaches of duty as a director provided that such limitation will not apply
to (i) acts or omissions that the director at the time of the breach knew or
believed were clearly in conflict with the best interests of the Company, (ii)
any liability for unlawful distributions under N.C. Gen. Stat. Section 55-8-33,
(iii) any transaction from which the director derived an improper personal
benefit, or (iv) acts or omissions occurring prior to the date the provision
became effective.
 
     Section 8 of the Underwriting Agreement filed as Exhibit 1.01 hereto also
contains certain provisions pursuant to which certain officers, directors and
controlling persons of the Company may be entitled to be indemnified by the
underwriters named therein.

ITEM 17.  UNDERTAKINGS
 
     1. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     2. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the provisions described in Item 15 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 Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of the 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 against the Registrant 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 appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
     3. The undersigned Registrant hereby undertakes that: (a) for purposes of
determining any liability under the Securities Act of 1933, 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; and (b) for the purpose of determining any liability under
the Securities Act of 1933, 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 such securities at that time
shall be deemed to be the initial bone fide offering thereof.

  As representatives of the several Underwriters
  named in Schedule I hereto,
c/o Goldman, Sachs & Co.
85 Broad Street,
New York, New York 10004.

Ladies and Gentlemen:

    Quintiles Transnational Corp., a North Carolina corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of 928,000 shareholders of the Company named in Schedule II hereto (the "Selling
Shareholders") propose, subject to the terms and conditions stated herein, to
sell to the Underwriters an aggregate of 2,272,000 shares and, in the case of
certain Selling Shareholders identified with an asterisk in Schedule II hereto
and at the election of the Underwriters, up to 480,000 additional shares of
Stock. The aggregate of 3,200,000 shares to be sold by the Company and the
Selling Shareholders hereto is herein called the "Firm Shares" and the aggregate
of 480,000 additional shares to be sold by the Selling Shareholders identified
with an asterisk in Schedule II hereto is herein called the "Optional Shares".
The Firm Shares and the Optional Shares that the Underwriters elect to purchase
pursuant to Section 2 hereof are herein collectively called the "Shares".

     It is understood and agreed to by all parties that the Company and the
Selling Shareholders are concurrently entering into an agreement (the
"International

<PAGE>   2

Underwriting Agreement") providing for the sale by the Company and the Selling
Shareholders of up to a total of 920,000 shares of Stock (the "International
Shares"), including the overallotment option thereunder, through arrangements
with certain underwriters outside the United States (the "International
Underwriters"), for whom Goldman Sachs International, Morgan Stanley & Co.
International Limited, Smith Barney Inc. and William Blair & Company, L.L.C. are
acting as lead managers. Anything herein or therein to the contrary
notwithstanding, the respective closings under this Agreement and the
International Underwriting Agreement are hereby expressly made conditional on
one another. The Underwriters hereunder and the International Underwriters are
simultaneously entering into an Agreement between U.S. and International
Underwriting Syndicates (the "Agreement between Syndicates") which provides,
among other things, for the transfer of shares of Stock between the two
syndicates. Two forms of prospectus are to be used in connection with the
offering and sale of shares of Stock contemplated by the foregoing, one relating
to the Shares hereunder and the other relating to the International Shares. The
latter form of prospectus will be identical to the former except for certain
substitute pages as included in the registration statement and amendments
thereto as mentioned below. Except as used in Sections 2, 3, 4, 9 and 11 herein,
and except as the context may otherwise require, references hereinafter to the
Shares shall include all the shares of Stock which may be sold pursuant to
either this Agreement or the International Underwriting Agreement, and
references herein to any prospectus whether in preliminary or final form, and
whether as amended or supplemented, shall include both the U.S.
and the international versions thereof.

    1.   (a)   The Company represents and warrants to, and agrees with, each of
         the Underwriters that:

    (i) A registration statement on Form S-3 (File No. 333-........) (the
    "Initial Registration Statement") in respect of the Shares has been filed
    with the Securities and Exchange Commission (the "Commission"); the Initial
    Registration Statement and any post-effective amendment thereto, each in the
    form heretofore delivered to you, and, excluding exhibits thereto but
    including all documents incorporated by reference in the prospectus
    contained therein, delivered to you for each of the other Underwriters, have
    been declared effective by the Commission in such form; other than a
    registration statement, if any, increasing the size of the offering (a "Rule
    462(b) Registration Statement"), filed pursuant to Rule 462(b) under the
    Securities Act of 1933, as amended (the "Act"), which became effective upon
    filing, no other document with respect to the Initial Registration
    Statement, any post-effective amendment thereto or the Rule 462(b)
    Registration Statement, if any, or document incorporated by reference
    therein has heretofore been filed with the Commission; and no stop order
    suspending the effectiveness of the Initial Registration Statement has been
    issued and no proceeding for that purpose has been initiated or threatened
    by the Commission (any preliminary prospectus included in the Initial
    Registration Statement or filed with the Commission pursuant to Rule 424(a)
    of the rules and regulations of the Commission under the Act is hereinafter
    called a "Preliminary Prospectus"); the various parts of the Initial


                                       2

<PAGE>   3

    Registration Statement and the Rule 462(b) Registration Statement, if any,
    including all exhibits thereto and including (A) the information contained
    in the form of final prospectus filed with the Commission pursuant to Rule
    424(b) under the Act in accordance with Section 5(a) hereof and deemed by
    virtue of Rule 430A under the Act to be part of the Initial Registration
    Statement at the time it was declared effective and (B) the documents
    incorporated by reference in the prospectus contained in the Initial
    Registration Statement at the time such part of the Initial Registration
    Statement became effective or such part of the Rule 462(b) Registration
    Statement, if any, became or hereafter becomes effective, each as amended at
    the time such part of the Initial Registration Statement became effective or
    such part of the Rule 462(b) Registration Statement, if any, became
    effective, are hereinafter collectively called the "Registration Statement";
    such final prospectus, in the form first filed pursuant to Rule 424(b) under
    the Act, is hereinafter called the "Prospectus"; any reference herein to any
    Preliminary Prospectus or the Prospectus shall be deemed to refer to and
    include the documents incorporated by reference therein pursuant to Item 12
    of Form S-3 under the Act, as of the date of such Preliminary Prospectus or
    Prospectus, as the case may be; any reference to any amendment or supplement
    to any Preliminary Prospectus or the Prospectus shall be deemed to refer to
    and include any documents filed after the date of such Preliminary
    Prospectus or Prospectus, as the case may be, under the Securities Exchange
    Act of 1934, as amended (the "Exchange Act"), and incorporated by reference
    in such Preliminary Prospectus or Prospectus, as the case may be; and any
    reference to any amendment to the Registration Statement shall be deemed to
    refer to and include any annual report of the Company filed pursuant to
    Section 13(a) or 15(d) of the Exchange Act after the effective date of the
    Initial Registration Statement that is incorporated by reference in the
    Registration Statement;

               (ii) No order preventing or suspending the use of any Preliminary
    Prospectus has been issued by the Commission, and each Preliminary
    Prospectus, at the time of filing thereof, conformed in all material
    respects to the requirements of the Act and the rules and regulations of the
    Commission thereunder, and did not contain an untrue statement of a material
    fact or omit to state a material fact required to be stated therein or
    necessary to make the statements therein, in the light of the circumstances
    under which they were made, not misleading; provided, however, that this
    representation and warranty shall not apply to any statements or omissions
    made in reliance upon and in conformity with information furnished in
    writing to the Company by an Underwriter through Goldman, Sachs & Co.
    expressly for use therein or by a Selling Shareholder expressly for use in
    the preparation of the answers therein to Item 7 of Form S-3;

               (iii) The documents incorporated by reference in the Prospectus, 
    when they became effective or were filed with the Commission, as the
    case may be, conformed in all material respects to the requirements of the
    Act or the Exchange Act, as applicable, and the rules and regulations of the
    Commission thereunder, and none of such documents contained an untrue
    statement of a material fact or


                                       3

<PAGE>   4

    omitted to state a material fact required to be stated therein or necessary
    to make the statements therein not misleading; and any further documents so
    filed and incorporated by reference in the Prospectus or any further
    amendment or supplement thereto, when such documents become effective or are
    filed with the Commission, as the case may be, will conform in all material
    respects to the requirements of the Act or the Exchange Act, as applicable,
    and the rules and regulations of the Commission thereunder and will not
    contain an untrue statement of a material fact or omit to state a material
    fact required to be stated therein or necessary to make the statements
    therein not misleading; provided, however, that this representation and
    warranty shall not apply to any statements or omissions made in reliance
    upon and in conformity with information furnished in writing to the Company
    by an Underwriter through Goldman, Sachs & Co. expressly for use therein;

               (iv) The Registration Statement conforms, and the Prospectus and
    any further amendments or supplements to the Registration Statement or the
    Prospectus will conform, in all material respects to the requirements of the
    Act and the rules and regulations of the Commission thereunder and do not
    and will not, as of the applicable effective date as to the Registration
    Statement and any amendment thereto and as of the applicable filing date as
    to the Prospectus and any amendment or supplement thereto, contain an untrue
    statement of a material fact or omit to state a material fact required to be
    stated therein or necessary to make the statements therein not misleading;
    provided, however, that this representation and warranty shall not apply to
    any statements or omissions made in reliance upon and in conformity with
    information furnished in writing to the Company by an Underwriter through
    Goldman, Sachs & Co. expressly for use therein or by a Selling Shareholder
    expressly for use in the preparation of the answers therein to Item 7 of
    Form S-3;

               (v) Other than as set forth or contemplated in the Prospectus, 
    since the respective dates as of which information is given in the
    Registration Statement and the Prospectus, there has not been any change in
    the capital stock or long-term debt of the Company and its subsidiaries,
    taken as a whole, or any material adverse change, or any development
    involving a prospective material adverse change, in the condition (financial
    or otherwise) or the earnings, business or operations of the Company and its
    subsidiaries, taken as a whole;

               (vi) The Company and each of its subsidiaries possesses all
    certificates, authorizations and permits issued by the appropriate federal,
    state or foreign regulatory authorities necessary to conduct their
    respective businesses, and neither the Company nor any such subsidiary has
    received any notice of proceedings relating to the revocation or
    modification of any such certificate, authorization or permit which, singly
    or in the aggregate, if the subject of an unfavorable decision, ruling or
    finding, would have a material adverse effect on the Company and its
    subsidiaries, taken as a whole, except as set forth or contemplated by the
    Prospectus;



                                       4

               (vii) The Company has been duly incorporated and is validly

    foreign corporation for the transaction of business and is in good standing
    under the laws of each other jurisdiction in which it owns or leases
    properties or conducts any business so as to require such qualification,
    except to the extent that the failure to be so qualified or be in good

    subsidiaries, taken as a whole. Each Significant Subsidiary (as defined
    below) of the Company has been duly incorporated or otherwise formed as a
    non- corporate entity, is validly existing as a corporation or other entity,
    as the case may be, in good standing under the laws of the jurisdiction of

    entity, as the case may be, for the transaction of business and is in good
    standing under the laws of each other jurisdiction in which it owns or
    leases properties or conducts any business so as to require such
    qualification, except to the extent that the failure to be so qualified or
    be in good standing would not have a material adverse effect on the Company
    and its subsidiaries, taken as a whole. As used in this Agreement, the term
    "Significant Subsidiary" shall have the meaning set forth for the term
    "Significant Subsidiary" in Rule 1-02(w) of Regulation S-X promulgated
    pursuant to the Securities Act;

               (viii) The Company has an authorized capitalization as set forth
    in the Prospectus, and all of the issued shares of capital stock of the
    Company have been duly authorized and validly issued, are fully paid and
    non-assessable and conform to the description of the Stock contained in the
    Prospectus; and all of the issued shares of capital stock of each
    Significant Subsidiary of the Company have been duly authorized and validly
    issued, are fully paid and non-assessable and (except for directors'
    qualifying shares and except as set forth in the Prospectus) are owned
    directly or indirectly by the Company, free and clear of all liens,
    encumbrances, equities or claims;

               (ix) The unissued Shares to be issued and sold by the Company to
    the Underwriters hereunder and under the International Underwriting
    Agreement have been duly authorized and, when issued and delivered against
    payment therefor as provided herein, will be validly issued and fully paid
    and non-assessable and will conform to the description of the Stock
    contained in the Prospectus;

               (x) The issue and sale of the Shares to be sold by the Company
    hereunder and under the International Underwriting Agreement, the compliance
    by the Company with all of the provisions of this Agreement and the
    International Underwriting Agreement and the consummation of the
    transactions herein and therein contemplated will not contravene any
    provision of applicable law or the Amended and Restated Articles of
    Incorporation or Amended and Restated Bylaws of the Company or any agreement
    or other instrument binding upon the Company



                                       5
<PAGE>   6

    or any of its subsidiaries that is material to the Company and its
    subsidiaries, taken as a whole, or any judgment, order or decree of any
    governmental body, agency or court having jurisdiction over the Company or
    any subsidiary, and no consent, approval, authorization or order of, or
    qualification with, any governmental body or agency is required for the
    issue and sale of the Shares by the Company or the consummation by the
    Company of the transactions contemplated by this Agreement and the
    International Underwriting Agreement except such consents, approvals,
    authorizations, registrations or qualifications as may be required under
    state or foreign securities or Blue Sky laws in connection with the purchase
    and distribution of the Shares by the Underwriters and the International
    Underwriters;

               (xi) Other than as set forth in the Prospectus, there are no
    legal or governmental proceedings pending to which the Company or any of its
    subsidiaries is a party or of which any property of the Company or any of
    its subsidiaries is the subject which, if determined adversely to the
    Company or any of its subsidiaries, would individually or in the aggregate
    have a material adverse effect on the current or future consolidated
    financial position, shareholders' equity or results of operations of the
    Company and its subsidiaries, taken as a whole; and, to the best of the
    Company's knowledge, no such proceedings are threatened or contemplated by
    governmental authorities or threatened by others;

               (xii) Neither the Company nor any of its subsidiaries has taken,
    directly, any action which was designed to or which has constituted or which
    might reasonably be expected to cause or result in stabilization or
    manipulation of the price of any security of the Company to facilitate the 
    sale or resale of the Stock;

               (xiii) The Company is not and, after giving effect to the
    offering and sale of the Shares, will not be an "investment company" "unit
    investment trust", "closed-end investment company", "face-amount certificate
    company" or an entity "controlled" by an "investment company" that is
    required to be registered under Section 8 of the United States Investment
    Company Act of 1940, as amended (the "Investment Company Act");

               (xiv) The Company and its subsidiaries (A) are in compliance with
    any and all applicable foreign, federal, state and local laws and
    regulations relating to the protection of human health or safety, the
    environment or any hazardous or toxic substances or wastes, pollutants or
    contaminants ("Environmental Laws"), (B) have received all permits, licenses
    or other approvals required of them under applicable Environmental Laws to
    conduct their respective businesses and (C) are in compliance with all terms
    and conditions of any such permit, license or approval, except where such
    noncompliance with Environmental Laws, failure to receive required permits,
    licenses or other approvals or failure to comply with the terms and
    conditions of such permits, licenses or approvals would not, singly or in
    the aggregate, have a material adverse effect on the Company and its
    subsidiaries, taken as a whole;

               (xv) The Company has conducted a review of the effect of
    Environmental Laws on the current and former businesses, operations and



                                       6
<PAGE>   7

    properties of the Company and its subsidiaries, in the course of which it
    identified and evaluated potential associated costs and liabilities
    (including, without limitation, any capital or operating expenditures
    required for clean-up or closure of any property, or compliance with
    Environmental Laws or any permit, license or approval, any related
    constraints on operating activities or any potential liabilities to third
    parties). On the basis of such review, the Company has reasonably concluded
    that such associated costs and liabilities would not, singly or in the
    aggregate, have a material adverse effect on the Company and its
    subsidiaries, taken as a whole;

               (xvi)    The use of the proceeds from the sale of the Securities
    will not violate or result in a violation of Section 7 of the Exchange
    Act, or any regulation promulgated thereunder, including, without
    limitation, Regulations G, T, U, and X of the Board of Governors of the
    Federal Reserve System;

               (xvii) Ernst & Young LLP, who have certified certain financial
    statements of the Company and its subsidiaries, are, to the best of the
    Company's knowledge, independent public accountants as required by the Act
    and the rules and regulations of the Commission thereunder;

               (xviii) This Agreement has been duly authorized, executed and
    delivered by the Company; 

               (xix)   There are no contracts, agreements or understandings 
    between the Company and any person granting such person the right (A) to 
    require the Company to file a registration statement under the Securities 
    Act with respect to any securities of the Company, except as disclosed in 
    the Registration Statement or (B) to require the Company to include 
    securities in the securities registered pursuant to the Registration
    Statement, except any such right that has been effectively waived or
    satisfied by the inclusion of securities in the Registration Statement;

               (xx) The statements set forth in the Prospectus under the caption
    "Description of Capital Stock", insofar as they purport to constitute a
    summary of the terms of the Stock, are accurate, complete and fair; and

               (xxi) Certain of the directors, officers and shareholders of the
    Company listed in Schedule III hereto who are not Selling Shareholders have
    each entered into a written agreement with the Company in the form of

    originals of each Lock-up Agreement have been delivered to you.

         (b) Each of the Selling Shareholders severally represents and warrants
    to, and agrees with, each of the Underwriters and the Company that:

               (i) All consents, approvals, authorizations and orders necessary

    such counsel may rely as to all matters governed by North Carolina law
    upon the opinion referred to in subsection (c) of this Section;

         (c) Smith, Anderson, Blount, Dorsett, Mitchell & Jernigan, L.L.P.,
    counsel for the Company, shall have furnished to you their written opinion,
    dated such Time of Delivery, in form and substance satisfactory to you, to
    the effect that: 

         (i) The Company has been duly incorporated and is validly existing as a
    corporation in good standing under the laws of the North Carolina, with
    corporate power and authority to own its properties and conduct its business
    as described in the Prospectus;

               (ii) The Company has an authorized capitalization as set forth in
    the Prospectus, and all of the issued shares of capital stock of the Company
    (including the Shares being delivered at such Time of Delivery) have been
    duly authorized and validly issued, are fully paid and non-assessable and
    are not subject to any preemptive rights under any North Carolina statute or
    the Company's Amended and Restated Articles of Incorporation or Amended and
    Restated Bylaws; and the Shares conform to the description of the Stock
    contained in the Prospectus;

              (iii) The Company has been duly qualified as a foreign corporation
    for the transaction of business and is in good standing under the laws of
    each other jurisdiction in which it owns or leases properties or conducts
    any business so as to require such qualification, except to the extent that
    the failure to be so qualified or be in good standing would not have a
    material adverse effect on the Company and its subsidiaries taken as a whole
    (such counsel being entitled to rely in respect of the opinion in this
    clause upon opinions of local counsel and in respect of matters of fact upon
    certificates of officers of the Company and the significant subsidiaries of
    the Company, provided that such counsel shall state that they believe that
    both you and they are justified in relying upon such opinions and
    certificates);

              (iv) Each Significant Subsidiary of the Company has been duly
    incorporated or otherwise formed as a non-corporate entity and is validly
    existing as a corporation or other entity, as the case may be, in good
    standing under the laws of the jurisdiction of its organization; with
    corporate or other organizational power and authority to own its
    properties and to conduct its business as described in the Prospectus and
    has been duly qualified as a foreign corporation or other entity, as the
    case may be, for the transaction of business and is in good standing under
    the laws of each other jurisdiction in which it owns or leases properties or
    conducts any business so as to require such qualification, except to the
    extent that the failure to be so qualified or be in good standing would not
    have a material adverse effect on the Company and its subsidiaries, taken as
    a whole (such counsel being entitled to rely in respect of the opinion in
    this clause upon opinions of local counsel and in respect of matters of fact
    upon certificates of officers of the Company, provided that such counsel
    shall state that they believe that both you and they are justified in
    relying upon such opinions and certificates);

<PAGE>   18

               (v) To the best of such counsel's knowledge and other than as set
    forth in the Prospectus, there are no legal or governmental proceedings
    pending to which the Company or any of its subsidiaries is a party or of
    which any property of the Company or any of its subsidiaries is the subject
    which, if determined adversely to the Company or any of its subsidiaries,
    would individually or in the aggregate have a material adverse effect on the
    current consolidated financial position, shareholders' equity or results of
    operations of the Company and its subsidiaries; and, to the best of such
    counsel's knowledge, no such proceedings are threatened or contemplated by
    governmental authorities or threatened by others;

               (vi)     This Agreement and the International Underwriting
    Agreement have been duly authorized, executed and delivered by the Company;

               (vii)    The issue and sale of the Shares, and the compliance
    by the Company with all of the provisions of this Agreement and the
    International Underwriting Agreement and the consummation of the
    transactions herein and therein contemplated will not contravene (A) any
    provision of applicable federal or North Carolina law which in such
    counsel's experience is normally applicable to transactions of the type
    contemplated by this Agreement and the contravention of which would have a
    material adverse effect on the business of the Company and its Significant
    Subsidiaries, taken as a whole, (B) the Amended and Restated Articles of
    Incorporation or Amended and Restated Bylaws of the Company, (C) any
    agreement or other instrument filed as an exhibit to the Registration
    Statement or incorporated by reference in the Prospectus, or (D) to the
    best of such counsel's knowledge, any judgment, order or decree of any
    governmental body, agency or court having jurisdiction over the Company     
    or any Significant Subsidiary;

               (viii)   No consent, approval, authorization, order of, or
    qualification with, any governmental agency or body is required for the
    issue and sale of the Shares or the consummation by the Company of the
    transactions contemplated by this Agreement and the International
    Underwriting Agreement, except such consents, approvals, authorizations,
    registrations or qualifications as may be required under state or foreign
    securities or Blue Sky laws in connection with the purchase and distribution
    of the Shares by the Underwriters and the International Underwriters;

               (ix)     The statements set forth in the Prospectus under the 
    caption "Description of Capital Stock", insofar as they purport to
    constitute a summary of the terms of the Stock, under the caption "Certain
    U.S. Federal Tax Considerations for Non-U.S. Holders of Common Stock", and
    under the caption "Underwriting", insofar as they purport to describe the
    provisions of the laws and documents referred to therein, are accurate,
    complete and fair;

               (x)      The Company is not an "investment company" or an entity
    "controlled" by an "investment company", as such terms are defined in the
    Investment Company Act;



                                       18
<PAGE>   19

               (xi) The documents incorporated by reference in the Prospectus or
    any further amendment or supplement thereto made by the Company prior to
    such Time of Delivery (other than the financial statements and related
    schedules therein or other financial data derived from accounting records,
    as to which such counsel need express no opinion), when they became
    effective or were filed with the Commission, as the case may be, complied as
    to form in all material respects with the requirements of the Act or the
    Exchange Act, as applicable, and the rules and regulations of the Commission
    thereunder; and they have no reason to believe that any of such documents
    (other than the financial statements and related schedules therein or other
    financial data derived from accounting records), when such documents became
    effective or were so filed, as the case may be, contained, in the case of a
    registration statement which became effective under the Act, an untrue
    statement of a material fact or omitted to state a material fact required to
    be stated therein or necessary to make the statements therein not
    misleading, or, in the case of other documents which were filed under the
    Exchange Act with the Commission (other than the financial statements and
    related schedules therein or other financial data derived from
    accounting records), an untrue statement of a material fact or omitted to
    state a material fact necessary in order to make the statements therein, in
    the light of the circumstances under which they were made when such
    documents were so filed, not misleading; and 

         (xii) (A) The Registration Statement and the Prospectus and any further
    amendments and supplements thereto made by the Company prior to such Time of
    Delivery (other than the financial statements and related schedules therein
    or other financial data derived from accounting records, as to which such
    counsel need express no opinion) comply as to form in all material respects
    with the requirements of the Act and the rules and regulations thereunder;
    (B) no facts have come to the attention of such counsel which lead them to
    believe that, as of its effective date, the Registration Statement or any
    further amendment thereto made by the Company prior to such Time of Delivery
    (other than the financial statements and related schedules therein or other
    financial data derived from accounting records, as to which such counsel
    need express no opinion) contained an untrue statement of a material fact or
    omitted to state a material fact required to be stated therein or necessary
    to make the statements therein not misleading or that, as of its date, the
    Prospectus or any further amendment or supplement thereto made by the
    Company prior to such Time of Delivery (other than the financial statements
    and related schedules therein or other financial data derived from
    accounting records, as to which such counsel need express no opinion)
    contained an untrue statement of a material fact or omitted to state a 
    material fact necessary to make the statements therein, in the light of the
    circumstances under which they were made, not misleading or that, as of 
    such Time of Delivery, either the Registration Statement or the Prospectus 
    or any further amendment or supplement thereto made by the Company prior to
    such Time of Delivery (other than the financial statements and related 
    schedules therein or other financial data derived from accounting records, 
    as to which such counsel need express no opinion) contains an untrue



                                       19
<PAGE>   20

    statement of a material fact or omits to state a material fact necessary to
    make the statements therein, in the light of the circumstances under which
    they were made, not misleading; and (C) and they do not know of any
    amendment to the Registration Statement required to be filed or of any
    contracts or other documents of a character required to be filed as an
    exhibit to the Registration Statement or required to be incorporated by
    reference into the Prospectus or required to be described in the
    Registration Statement or the Prospectus which are not filed or
    incorporated by reference or described as required.

    In rendering their opinions contained in this Section 7(c), such counsel may
state that they express no opinion as to the laws of any jurisdiction outside
the United States. In rendering the opinion contained in clause (vi) of this
Section 7(c), such counsel may rely as to all matters governed by New York law
upon the opinion referred to in subsection (b) of this Section 7. With respect
to the matters referred to in clause (xii)(B) of this Section 7(c), such counsel
may state that their opinion and belief are based upon their review of the
Registration Statement and the Prospectus and any amendments or supplements
thereto made by the Company prior to such Time of Delivery and participation in
conferences and discussions with officers and other representatives of the
Company, representatives of the independent public accountants for the Company,
and representatives of the Underwriters at which the contents of the
Registration Statement and the Prospectus and any amendments or supplements
thereto made by the Company prior to such Time of Delivery and related matters
were discussed and, that, except to the extent set forth in clause (ix) of this
Section 7(c), they do not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Registration
Statement and the Prospectus and any amendments or supplements thereto made by
the Company prior to such Time of Delivery.

    (d) The respective counsel for each of the Selling Shareholders, as
indicated in Schedule II hereto, each shall have furnished to you their written
opinion with respect to each of the Selling Shareholders for whom they are
acting as counsel, dated such Time of Delivery, in form and substance
satisfactory to you, to the effect that:

               (i) A Power of Attorney and a Custody Agreement have been duly
    executed and delivered by such Selling Shareholder and constitute valid and
    binding agreements of such Selling Shareholder in accordance with their
    terms;

               (ii) This Agreement and the International Underwriting Agreement
    have been duly executed and delivered by or on behalf of such Selling
    Shareholder; and the sale of the Shares to be sold by such Selling
    Shareholder hereunder and thereunder and the compliance by such Selling
    Shareholder with all of the provisions of this Agreement and the
    International Underwriting Agreement, the Power of Attorney and the Custody
    Agreement and the consummation of the transactions herein and therein
    contemplated will not conflict with or result in a breach or violation of
    any terms or provisions of, or constitute a default under, any statute,
    indenture, mortgage, deed of trust, loan agreement or other agreement or
    instrument known to such counsel to which such Selling Shareholder is a
    party or 



                                       20
<PAGE>   21

    by which such Selling Shareholder is bound, or to which any of the
    property or assets of such Selling Shareholder is subject, nor will such
    action result in any violation of the provisions of the Articles of
    Incorporation and By-laws or other governing instrument of such Selling
    Shareholder if such Selling Shareholder is a corporation, the Partnership
    Agreement of such Selling Shareholder if such Selling Shareholder is a
    partnership, the governing trust agreement or other governing instrument of
    such Selling Shareholder if such selling Shareholder is a trust, or any
    order, rule or regulation known to such counsel of any court or governmental
    agency or body having jurisdiction over such Selling Shareholder or the
    property of such Selling Shareholder;

               (iii) No consent, approval, authorization or order of any court
    or governmental agency or body is required for the consummation of the
    transactions contemplated by this Agreement and the International
    Underwriting Agreement in connection with the Shares to be sold by such
    Selling Shareholder hereunder or thereunder, except such as shall have been
    specified in such opinion which have been duly obtained and are in full
    force and effect and such as may be required under state securities or Blue
    Sky laws in connection with the purchase and distribution of such Shares by
    the Underwriters or the International Underwriters;

               (iv) Immediately prior to such Time of Delivery such Selling
    Shareholder had good and valid title to the Shares to be sold at such Time
    of Delivery by such Selling Shareholder under this Agreement and the
    International Underwriting Agreement, free and clear of all liens,
    encumbrances, equities or claims, and full right, power and authority to
    sell, assign, transfer and deliver the Shares to be sold by such Selling
    Shareholder hereunder and thereunder; and

               (v) Good and valid title to such Shares, free and clear of all
    liens, encumbrances, equities or claims, has been transferred to each of
    the several Underwriters or International Underwriters, as the case may be,
    who have purchased such Shares in good faith and without notice of any such
    lien, encumbrance, equity or claim or any other adverse claim within the
    meaning of the Uniform Commercial Code. 

    In rendering the opinion in subparagraph (iv) such counsel may rely upon a
certificate of such Selling Shareholder in respect of matters of fact as to
ownership of, and liens, encumbrances, equities or claims on the Shares sold by
such Selling Shareholder, provided that such counsel shall state that they
believe that both you and they are justified in relying upon such certificate;

    (e) On the date of the Prospectus at a time prior to the execution of this
Agreement, at 9:30 a.m., New York City time, on the effective date of any
post-effective amendment to the Registration Statement filed subsequent to the
date of this Agreement and also at each Time of Delivery (A) Ernst & Young LLP

respective date of delivery thereof, in form and substance satisfactory to you,
to the effect set forth in Annex I(a) hereto, (B) Coopers & Lybrand shall have
furnished to you and the Company a letter or letters, dated the respective date

                                       21
<PAGE>   22

satisfactory to you, to the effect set forth in Annex 1(b) and (C) KPMG shall
have furnished to you and the Company a letter or letters, dated the respective
date of delivery thereof, in form and substance satisfactory to you, to the
effect set forth in Annex 1(c).

    (f) Since the respective dates as of which information is given in the
Prospectus, there shall not have been any change in the capital stock or
long-term debt of the Company or any of its subsidiaries, taken as a whole, or
any change, or any development involving a prospective change, in the condition
(financial or otherwise) or the earnings, business or operations of the Company
and its subsidiaries, taken as a whole, otherwise than as set forth or
contemplated in the Prospectus, the effect of which, in any such case described
in this subsection (f), is in the judgment of the Representatives so material
and adverse as to make it impracticable or inadvisable to proceed with the
public offering or the delivery of the Shares being delivered at such Time of
Delivery on the terms and in the manner contemplated in the Prospectus;

    (g) On or after the date hereof (i) no downgrading shall have occurred in
the rating accorded the Company's debt securities by any "nationally recognized
statistical rating organization", as that term is defined by the Commission for
purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall
have publicly announced that it has under surveillance or review, with possible
negative implications, its rating of any of the Company's debt securities; 

    (h) On or after the date hereof there shall not have occurred any of the
following: (i) a suspension or material limitation in trading in securities
generally on the New York Stock Exchange or on NASDAQ; (ii) a suspension or
material limitation in trading in the Company's securities on NASDAQ; (iii) a
general moratorium on commercial banking activities declared by either Federal
or New York State authorities; (iv) the outbreak or escalation of hostilities
involving the United States or the declaration by the United States of a
national emergency or war, if the effect of any such event specified in clause
(iv) above in the judgment of the Representatives makes it impracticable or
inadvisable to proceed with the public offering or the delivery of the Shares
being delivered at such Time of Delivery on the terms and in the manner
contemplated in this Agreement and in the Prospectus;

    (i) The Shares to be sold by the Company and the Selling Shareholders at
such Time of Delivery shall have been duly listed for quotation on NASDAQ;

    (j) The Company has obtained and delivered to the Underwriters executed

Company and of the Selling Shareholders, respectively, satisfactory to you as to
the accuracy of the representations and warranties of the Company and the
Selling Shareholders, respectively, herein at and as of such Time of Delivery,
as to the performance by the Company and the Selling Shareholders of all of
their respective obligations hereunder 



                                       22
<PAGE>   23
to be performed at or prior to such Time of Delivery, and as to such other
matters as you may reasonably request, and the Company shall have furnished or
caused to be furnished certificates as to the matters set forth in subsections
(a) and (f) of this Section, and as to such other matters as you may reasonably
request; and

    (l) The Company shall have complied with the provisions of Section 5(c)
hereof with respect to the furnishing of prospectuses on the New York Business
Day next succeeding the date of this Agreement.

    8.   (a)   The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will periodically reimburse each Underwriter for any
legal or other expenses reasonably incurred by such Underwriter in connection
with investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. or by any Selling Shareholder expressly for use
therein; and provided, further, that the Company shall not be liable to any
Underwriter under the indemnity agreement in this subsection (a) with respect to
any Preliminary Prospectus to the extent that any such loss, claim, damage or
liability of such Underwriter results from the fact that such Underwriter sold
Shares to a person as to whom it shall be established that there was not sent or
given, at or prior to the written confirmation of such sale, a copy of the
Prospectus (excluding documents incorporated by reference) or of the Prospectus
as then amended or supplemented (excluding documents incorporated by reference)
in any case where such delivery is required by the Act if the Company has
previously furnished copies thereof in sufficient quantity to such Underwriter
and the loss, claim, damage or liability of such Underwriter results from an
untrue statement or omission of a material fact contained in the Preliminary
Prospectus which was identified in writing prior to the date hereof to such
Underwriter and corrected in the Prospectus (excluding document incorporated by
reference) or in the Prospectus as then amended or supplemented (excluding
documents incorporated by reference).

    (b) Each of the Selling Shareholders will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are 



                                       23
<PAGE>   24

based upon (i) an untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement or the Prospectus or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Selling Shareholder expressly for
use therein, or (ii) the failure of such Selling Shareholder at or prior to the
written confirmation of the sale of the Shares to be sold by such Selling
Shareholder to send or deliver a copy of an amended Preliminary Prospectus or
Prospectus (or the Prospectus as amended or supplemented) to the person
asserting any such losses, claims, damages or liabilities against any
Underwriter, which person purchased the Shares which are the subject thereof,
and the untrue statement or alleged untrue statement or omission or alleged
omission of a material fact made in such Preliminary Prospectus was corrected in
the amended Preliminary Prospectus or the Prospectus (or the Prospectus as
amended and supplemented); and each Selling Shareholder will periodically
reimburse each Underwriter for any legal or other expenses reasonably incurred
by such Underwriter in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that the
amount of such indemnity shall be limited to the total net proceeds received by
each such Selling Shareholder from the offering of Shares purchased under this
Agreement (before deducting expenses).

    (c) Each Underwriter will indemnify and hold harmless the Company and each
Selling Shareholder against any losses, claims, damages or liabilities to which
the Company or such Selling Shareholder may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, the Registration
Statement or the Prospectus or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by such
Underwriter through Goldman, Sachs & Co. expressly for use therein; and will
reimburse the Company and each Selling Shareholder for any legal or other
expenses reasonably incurred by the Company or such Selling Shareholder in
connection with investigating or defending any such action or claim as such
expenses are incurred.

    (d) Promptly after receipt by an indemnified party under subsection (a), (b)
or (c) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against an indemnifying party
under such 



                                       24

<PAGE>   25

subsection, notify the indemnifying party in writing of the commencement
thereof; but the omission so to notify the indemnifying party shall not relieve
it from any liability which it may have to any indemnified party otherwise than
under such subsection. In case any such action shall be brought against any
indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it shall wish, jointly with any other indemnifying party
similarly notified, to assume the defense thereof, with counsel satisfactory to
such indemnified party (which shall not, except with the consent of the
indemnified party, be counsel to the indemnifying party), and, after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party shall not be liable to such
indemnified party under such subsection for any legal expenses of other counsel
or any other expenses, in each case subsequently incurred by such indemnified
party, in connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or claim
in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to or an admission
of fault, culpability or a failure to act, by or on behalf of any indemnified
party.

    (e) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a), (b)
or (c) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Shareholders on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (d) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Shareholders on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Selling Shareholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering of the Shares purchased under this
Agreement (before deducting expenses) received by the Company and the Selling
Shareholders bear to the total underwriting discounts and commissions received
by the Underwriters with respect to the Shares purchased under this 




                                       25

Agreement, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Selling Shareholders on the one hand or the
Underwriters on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, each of the Selling Shareholders and the Underwriters agree that it
would not be just and equitable if contributions pursuant to this subsection (e)
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (e). The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (e) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (e), (i) no Selling Shareholder shall be required
to contribute any amount by which the total price at which the Shares sold by
such Selling Shareholder and distributed to the public were offered to the
public (before deducting expenses) exceeds the amount of any damages that such
Selling Shareholder has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission, and (ii) no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Shares underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages which
such Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this subsection
(e) to contribute are several in proportion to their respective underwriting
obligations and not joint. The remedies provided for in this Section 8 are not
exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

    (f) The obligations of the Company and the Selling Shareholders under this
Section 8 shall be in addition to any liability which the Company and the
respective Selling Shareholders may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 8 shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company (including any person
who, with his or her consent, is named in the Registration Statement as about to
become a director of the Company) and to each person, if any, who controls the
Company or any Selling Shareholder within the meaning of the Act.

    9. (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Company and the Selling Shareholders shall be entitled to a further
period of thirty-six hours within which to procure another party or other
parties satisfactory to you to purchase such Shares on such terms. In the event
that, within the respective prescribed periods, you notify the Company and the
Selling Shareholders that you have so arranged for the purchase of such Shares,
or the Company and the Selling Shareholders notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Shareholders shall have the right to postpone such Time of Delivery for a period
of not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "Underwriter" as used in this Agreement
shall include any person substituted under this Section with like effect as if
such person had originally been a party to this Agreement with respect to such
Shares.

    (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Shareholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all of the Shares to be purchased at such Time of
Delivery, then the Company and the Selling Shareholders shall have the right to
require each non-defaulting Underwriter to purchase the number of Shares which
such Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default. 

    (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Shareholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Company and the Selling Shareholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Selling Shareholders to sell the Optional
Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company or the Selling Shareholders, except
for the expenses to be borne by the Company and the Selling Shareholders and the
Underwriters as provided in Section 6 hereof and the indemnity and contribution



                                       27

agreements in Section 8 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

    10. The respective indemnities, agreements, representations, warranties and
other statements of the Company, the Selling Shareholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company, or any of the Selling Shareholders, or any officer
or director or controlling person of the Company, or any controlling person of
any Selling Shareholder, and shall survive delivery of and payment for the
Shares.

    11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Shareholders shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Company and the Selling Shareholders as provided herein, the Company and each of
the Selling Shareholders pro rata (based on the number of Shares to be sold by
the Company and such Selling Shareholder hereunder) will reimburse the
Underwriters through you for all out-of-pocket expenses approved in writing by
you, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Shares not so delivered, but the Company and the Selling Shareholders shall then
be under no further liability to any Underwriter in respect of the Shares not so
delivered except as provided in Sections 6 and 8 hereof.

    12. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives; and in all dealings with any Selling Shareholder hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Shareholder made or given by any
or all of the Attorneys-in-Fact for such Selling Shareholder.

    All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; if to any Selling Shareholder shall be delivered or sent by mail,
telex or facsimile transmission to counsel for such Selling Shareholder at its
address set forth in Schedule II hereto; and if to the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of the
Company set forth in the Registration Statement, Attention: Secretary; provided,
however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall
be delivered or sent by mail, telex or facsimile transmission to such
Underwriter at its address set forth in its Underwriters' Questionnaire or telex
constituting such Questionnaire, which address will be supplied to the Company
or the 



                                       28

Selling Shareholders by you upon request. Any such statements, requests, notices
or agreements shall take effect upon receipt thereof.

    13. This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and the Selling Shareholders and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and each person who controls the Company, any Selling Shareholder or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign by reason merely of such purchase.

    14.  Time shall be of the essence of this Agreement.  As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

    15. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK. 

    16. This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

    If the foregoing is in accordance with your understanding, please sign and
return to us ..... counterparts hereof, and upon the acceptance hereof by you,
on behalf of each of the Underwriters, this letter and such acceptance hereof
shall constitute a binding agreement among each of the Underwriters, the Company
and each of the Selling Shareholders. It is understood that your acceptance of
this letter on behalf of each of the Underwriters is pursuant to the authority
set forth in a form of Agreement among Underwriters (U.S. Version), the form of
which shall be submitted to the Company and the Selling Shareholders for
examination upon request, but without warranty on your part as to the authority
of the signers thereof.

  As representatives of the several Underwriters
  named in Schedule I hereto,
Peterborough Court,

London EC4A 2BB, England.
Ladies and Gentlemen:

    Quintiles Transnational Corp., a North Carolina corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of 232,000 shares of Common Stock, $.01 par value ("Stock") of the Company and
the shareholders of the Company named in Schedule II hereto (the "Selling
Shareholders") propose, subject to the terms and conditions stated herein, to
sell to the Underwriters an aggregate of 568,000 shares and, in the case of
certain Selling Shareholders identified with an asterisk in Schedule II hereto
and at the election of the Underwriters, up to 120,000 additional shares of
Stock. The aggregate of 800,000 shares to be sold by the Company and the Selling
Shareholders is herein called the "Firm Shares" and the aggregate of 120,000
additional shares to be sold by the Selling Shareholders identified with an
asterisk in Schedule II hereto is herein called the "Optional Shares". The Firm
Shares and the Optional Shares which the Underwriters elect to purchase pursuant
to Section 2 hereof are herein collectively called, the "Shares".

    It is understood and agreed to by all parties that the Company and the
Selling Shareholders are concurrently entering into an agreement, a copy of
which is attached hereto (the "U.S. Underwriting Agreement"), providing for the
sale by the Company and the Selling Shareholders of up to a total of 3,680,000
shares of Stock (the "U.S. Shares"), including the overallotment option
thereunder, through arrangements with certain underwriters in the United States
(the "U.S. Underwriters"), for whom Goldman, Sachs & Co., Morgan Stanley & Co.
Incorporated, Smith Barney Inc. and William Blair & Company, L.L.C. are acting
as representatives. Anything herein or therein to the contrary notwithstanding,
the respective closings under this Agreement and the U.S. Underwriting Agreement
are hereby expressly made conditional on one another. The Underwriters hereunder
and the U.S. Underwriters are 




<PAGE>   2

simultaneously entering into an Agreement between U.S. and International
Underwriting Syndicates (the "Agreement between Syndicates") which provides,
among other things, for the transfer of shares of Stock between the two
syndicates and for consultation by the Lead Manager hereunder with Goldman,
Sachs & Co. prior to exercising the rights of the Underwriters under Section 7
hereof. Two forms of prospectus are to be used in connection with the offering
and sale of shares of Stock contemplated by the foregoing, one relating to the
Shares hereunder and the other relating to the U.S. Shares. The latter form of
prospectus will be identical to the former except for certain substitute pages
as included in the registration statement and amendments thereto as mentioned
below. Except as used in Sections 2, 3, 4, 9 and 11 herein, and except as
context may otherwise require, references hereinafter to the Shares shall
include all of the shares of Stock which may be sold pursuant to either this
Agreement or the U.S. Underwriting Agreement, and references herein to any
prospectus whether in preliminary or final form, and whether as amended or
supplemented, shall include both the U.S. and the international versions
thereof.

    In addition, this Agreement incorporates by reference certain provisions
from the U.S. Underwriting Agreement (including the related definitions of
terms, which are also used elsewhere herein) and, for purposes of applying the
same, references (whether in these precise words or their equivalent) in the
incorporated provisions to the "Underwriters" shall be to the Underwriters
hereunder, to the "Shares" shall be to the Shares hereunder as just defined, to
"this Agreement" (meaning therein the U.S. Underwriting Agreement) shall be to
this Agreement (except where this Agreement is already referred to or as the
context may otherwise require) and to the representatives of the Underwriters or
to Goldman, Sachs & Co. shall be to the addressees of this Agreement and to
Goldman Sachs International ("GSI"), and, in general, all such provisions and
defined terms shall be applied mutatis mutandis as if the incorporated
provisions were set forth in full herein having regard to their context in this
Agreement as opposed to the U.S. Underwriting Agreement.

    1. The Company and each of the several Selling Shareholders hereby make to
the Underwriters the same respective representations, warranties and agreements
as are set forth in Section 1 of the U.S. Underwriting Agreement, which Section
is incorporated herein by this reference.

    2.   Subject to the terms and conditions herein set forth, (a) each Selling
Shareholder agrees that the purchase price per share at which the Underwriters
will purchase Shares from such Selling Shareholder (as set forth in clause (b)
below) shall be the same as the purchase price per share at which the Company
sells shares to be purchased by the Underwriters from the Company hereunder,
(b) the Company and each of the Selling Shareholders agree, severally and not
jointly, to sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Company and each of the
Selling Shareholders, at a purchase price per share of $............, the
number of Firm Shares (to be adjusted by you so as to eliminate fractional
shares) determined by multiplying the aggregate number of Firm Shares to be
sold by the Company and each of the Selling Shareholders as set forth opposite
their respective names in Schedule II hereto by a fraction, the numerator of
which is the aggregate number of Firm Shares to be purchased by such
Underwriter as set forth opposite the name of such Underwriter in Schedule I
hereto and the denominator of which is the aggregate number of Firm Shares to
be purchased by all the Underwriters from 


                                      -2-

<PAGE>   3


the Company and all the Selling Shareholders hereunder and (c) in the event and
to the extent that the Underwriters shall exercise the election to purchase
Optional Shares as provided below, each of the Selling Shareholders identified
with an asterisk in Schedule II hereto, agrees, severally and not jointly, to
sell to each of the Underwriters, and each of the Underwriters agrees, severally
and not jointly, to purchase from each of the Selling Shareholders, at the
purchase price per share set forth in clause (b) of this Section 2, that portion
of the number of Optional Shares as to which such election shall have been
exercised (to be adjusted by you so as to eliminate fractional shares)
determined by multiplying such number of Optional Shares by a fraction the
numerator of which is the maximum number of Optional Shares which such
Underwriter is entitled to purchase as set forth opposite the name of such
Underwriter in Schedule I hereto and the denominator of which is the maximum
number of Optional Shares that all of the Underwriters are entitled to purchase
hereunder.

    The Selling Shareholders identified with an asterisk in Schedule II hereto,
hereby grant, severally and not jointly, to the Underwriters the right to
purchase at their election up to 120,000 Optional Shares, at the purchase price
per share set forth in the paragraph above, for the sole purpose of covering
overallotments in the sale of the Firm Shares. Any such election to purchase
Optional Shares shall be made in proportion to the maximum number of Optional
Shares to be sold by each Selling Shareholder as set forth in Schedule II
hereto. Any such election to purchase Optional Shares may be exercised only by
written notice from you to the Attorneys-in-Fact, given within a period of 30
calendar days after the date of this Agreement and setting forth the aggregate
number of Optional Shares to be purchased and the date on which such Optional
Shares are to be delivered, as determined by you but in no event earlier than
the First Time of Delivery (as defined in Section 4 hereof) or, unless you and
the Attorneys-in-Fact otherwise agree in writing, earlier than two or later than
ten business days after the date of such notice.

    3. Upon the authorization by GSI of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus and in the forms of Agreement among
Underwriters (International Version) and Selling Agreements, which have been
previously submitted to the Company and the Selling Shareholders by you. Each
Underwriter hereby makes to and with the Company and the Selling Shareholders
the representations and agreements of such Underwriter as a member of the
selling group contained in Sections 3(d) and 3(e) of the form of Selling
Agreements.

    4. (a) The Shares to be purchased by each Underwriter hereunder, in
definitive form, and in such authorized denominations and registered in such
names as Goldman, Sachs & Co. may request upon at least two business days' prior
notice to the Company and the Selling Shareholders shall be delivered by or on
behalf of the Company and the Selling Shareholders to Goldman, Sachs & Co., for
the account of such Underwriter, against payment by or on behalf of such
Underwriter of the purchase price therefor in United States dollars by wire
transfer of immediately available funds to an account or accounts designated by
the Custodian and the Company. The Company and the Selling Shareholders will
cause the certificates representing the Shares to be made available for checking
and packaging at least one full business day prior to the Time of Delivery (as
defined below) with respect thereto at the office of Goldman, Sachs & Co., 85
Broad Street, New York, New York 10004 (the "Designated Office"). The time and

date for delivery of the Firm Shares is herein called the "First Time of
Delivery", such time and date for delivery of the Firm Optional Shares, if not

each such time and date for delivery is herein called a "Time of Delivery".

         (b) The documents to be delivered at each Time of Delivery by or on

incorporated herein by this reference.

    6.   The Company, each of the Selling Shareholders, and the Underwriters
hereby agree with respect to certain expenses on the same terms as are set forth

obligations of the Underwriters hereunder shall be subject, in their discretion,
at each Time of Delivery to the condition that all representations and
warranties and other statements of the Company, and the Selling Shareholders
herein are, at and as of each Time of Delivery, true and correct, the condition
that the Company and the Selling Shareholders shall have performed all of their
respective obligations hereunder theretofore to be performed, and additional
conditions identical to those set forth in Section 7 of the U.S. Underwriting
Agreement, which Section is incorporated herein by this reference.

    8. (a) The Company will indemnify and hold harmless each Underwriter against
any losses, claims, damages or liabilities, joint or several, to which such
Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise

through GSI or by any Selling Shareholder expressly for use therein; and
provided, further, that the Company shall not be liable to any Underwriter under
the indemnity agreement in this subsection (a) with respect to any Preliminary

Underwriter results from the fact that such Underwriter sold Shares to a person
as to whom it shall be established that there was not sent or given, at or prior
to the written confirmation of such sale, a copy of the Prospectus (excluding
documents incorporated by reference) or of the Prospectus as then amended or
supplemented (excluding documents incorporated by reference) in any case where
such delivery is required by the Act if the Company has previously furnished
copies thereof in sufficient quantity to such Underwriter and the loss, claim,
damage or liability of such Underwriter results from an untrue statement or
omission of a material fact contained in the Preliminary Prospectus which was
identified in writing prior to the date hereof to such Underwriter and corrected
in the Prospectus (excluding documents incorporated by reference) or in the
Prospectus as then amended or supplemented (excluding documents incorporated by
reference).

    (b) Each of the Selling Shareholders will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon (i) an untrue statement or
alleged untrue statement of a material fact contained in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Selling Shareholder expressly for use therein,
or (ii) the failure of such Selling Shareholder at or prior to the written
confirmation of the sale of the Shares to be sold by such Selling Shareholder to
send or deliver a copy of an amended Preliminary Prospectus or Prospectus (or
the Prospectus as amended or supplemented) to the person asserting any such
losses, claims, damages or liabilities against any Underwriter, which person
purchased the Shares which are the subject thereof, and the untrue statement or
alleged untrue statement or omission or alleged omission of a material fact made
in such Preliminary Prospectus was corrected in the amended Preliminary
Prospectus or the Prospectus (or the Prospectus as amended and supplemented);
and each Selling Shareholder will periodically reimburse each Underwriter for



                                      -5-
<PAGE>   6

any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that the amount of such indemnity
shall be limited to the total net proceeds received by each such Selling
Shareholder from the offering of Shares purchased under this Agreement (before
deducting expenses).

    (c) Each Underwriter will indemnify and hold harmless the Company and each
Selling Shareholder against any losses, claims, damages or liabilities to which
the Company or such Selling Shareholder may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, the Registration
Statement or the Prospectus or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by such
Underwriter through GSI expressly for use therein; and will reimburse the
Company and each Selling Shareholder for any legal or other expenses reasonably
incurred by the Company or such Selling Shareholder in connection with
investigating or defending any such action or claim as such expenses are
incurred.

    (d) Promptly after receipt by an indemnified party under subsection (a), (b)
or (c) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against an indemnifying party
under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (which shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement 



                                      -6-

<PAGE>   7

as to or an admission of fault, culpability or a failure to act, by or on behalf
of any indemnified party.

    (e) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a), (b)
or (c) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Shareholders on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (d) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Shareholders on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Selling Shareholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering of the Shares purchased under this
Agreement (before deducting expenses) received by the Company and the Selling
Shareholders bear to the total underwriting discounts and commissions received
by the Underwriters with respect to the Shares purchased under this Agreement,
in each case as set forth in the table on the cover page of the Prospectus. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Selling Shareholders on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company, each
of the Selling Shareholders and the Underwriters agree that it would not be just
and equitable if contributions pursuant to this subsection (e) were determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this subsection (e). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (e) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (e), (i) no Selling Shareholder shall be required to contribute any
amount by which the total price at which the Shares sold by such Selling
Shareholder and distributed to the public were offered to the public (before
deducting expenses) exceeds the amount of any damages that such Selling
Shareholder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and (ii) no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Shares underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages which
such Underwriter has otherwise been required to pay by 



                                      -7-

<PAGE>   8

reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Underwriters'
obligations in this subsection (e) to contribute are several in proportion to
their respective underwriting obligations and not joint. The remedies provided
for in this Section 8 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to any indemnified party at law or in
equity.

    (f) The obligations of the Company and the Selling Shareholders under this
Section 8 shall be in addition to any liability which the Company and the
respective Selling Shareholders may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 8 shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company (including any person
who, with his or her consent, is named in the Registration Statement as about to
become a director of the Company) and to each person, if any, who controls the
Company or any Selling Shareholder within the meaning of the Act.

    9. (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Company and the Selling Shareholders shall be entitled to a further
period of thirty-six hours within which to procure another party or other
parties satisfactory to you to purchase such Shares on such terms. In the event
that, within the respective prescribed periods, you notify the Company and the
Selling Shareholders that you have so arranged for the purchase of such Shares,
or the Company and the Selling Shareholders notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Shareholders shall have the right to postpone such Time of Delivery for a period
of not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "Underwriter" as used in this Agreement
shall include any person substituted under this Section with like effect as if
such person had originally been a party to this Agreement with respect to such
Shares.

       (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Shareholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of Delivery,
then the Company and the Selling Shareholders shall have the right to require
each non-defaulting Underwriter to purchase the number of Shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such 



                                      -8-
<PAGE>   9

defaulting Underwriter or Underwriters for which such arrangements have not been
made; but nothing herein shall relieve a defaulting Underwriter from liability
for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Shareholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all the Shares to be purchased at such Time of Delivery, or
if the Company and the Selling Shareholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Selling Shareholders to sell the Optional
Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company or the Selling Shareholders, except
for the expenses to be borne by the Company and the Selling Shareholders and the
Underwriters as provided in Section 6 hereof and the indemnity and contribution
agreements in Section 8 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

    10. The respective indemnities, agreements, representations, warranties and
other statements of the Company, the Selling Shareholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company or any of the Selling Shareholders, or any officer
or director or controlling person of the Company or any controlling person of
any Selling Shareholders, and shall survive delivery of and payment for the
Shares.

    11. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by GSI on your behalf; and in all dealings with any
Selling Shareholder hereunder, you and the Company shall be entitled to act and
rely upon any statement, request, notice or agreement on behalf of such Selling
Shareholder made or given by any or all of the Attorneys-in-Fact for such
Selling Shareholder.

    All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the Underwriters in care of GSI, Peterborough Court,
133 Fleet Street, London EC4A 2BB, England, Attention: Equity Capital Markets,
Telex No. 94012165, facsimile transmission No. (071) 774-1550; if to any Selling
Shareholder shall be delivered or sent by mail, telex or facsimile transmission
to counsel for such Selling Shareholder at its address set forth in Schedule II
hereto; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
mail, telex or facsimile transmission to such Underwriter at its address set
forth in its Underwriters' Questionnaire, or telex constituting such
Questionnaire, which address will be supplied to the Company or the Selling
Shareholders by

GSI upon request. Any such statements, requests, notices or agreements shall
take effect upon receipt thereof.

    12. This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and the Selling Shareholders and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and each person who controls the Company, any Selling Shareholder or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign by reason merely of such purchase.

    13. Time shall be of the essence of this Agreement.

    14. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA.

    15. This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts, each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

    If the foregoing is in accordance with your understanding, please sign and
return to us one for the Company and one for each of the Lead Managers or Lead
Managing Underwriters plus one for each counsel and the Custodian, if any,
counterparts hereof, and upon the acceptance hereof by you, on behalf of each of
the Underwriters, this letter and such acceptance hereof shall constitute a
binding agreement among each of the Underwriters, the Company and each of the
Selling Shareholders. It is understood that your acceptance of this letter on
behalf of each of the Underwriters is pursuant to the authority set forth in a
form of Agreement among Underwriters (International Version), the form of which
shall be furnished to the Company and the Selling Shareholders for examination
upon request, but without warranty on your part as to the authority of the
signers thereof.

      Re:  Registration Statement on Form S-3

Ladies and Gentlemen:

        We are counsel for Quintiles Transnational Corp. (the "Company") in
connection with the issuance and sale by the Company of up to 1,160,000 shares
of the Company's Common Stock, $0.01 par value per share, and the sale by
certain shareholders of the Company of up to 3,440,000 shares of the Company's
Common Stock (including up to 600,000 shares subject to the underwriters'
over-allotment option).  These shares are described in the Company's
Registration Statement on Form S-3 filed with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Act"), on February 7, 1997 with which this opinion will be filed as an exhibit
(the Registration Statement, as amended, being hereinafter referred to as the
"Registration Statement").

        We have examined the Amended and Restated Articles of Incorporation and
Amended and Restated Bylaws of the Company, the minutes of the meetings of the
Board of Directors of the Company relating to the authorization and the
issuance of securities and such other documents, records, and matters of law as
we have deemed necessary for purposes of this opinion.  In our examination, we
have assumed the genuineness of all signatures, the authenticity of all
documents as originals, the conformity to originals of all documents submitted
to us as certified copies or photocopies, and the authenticity of the originals
of such latter documents.  In rendering the opinions set forth below, we have
relied on a certificate of a Company officer, whom we believe is responsible. 
We have relied solely on such

certificate and the representations and warranties contained in the
Underwriting Agreements (as defined below) in rendering the opinion set forth
in paragraph 2 below and we believe such reliance to be reasonable.


      Based upon the foregoing, it is our opinion, as of the date hereof, that:

      1.  The 1,160,000 shares of Common Stock of the Company which are being
          registered pursuant to the Registration Statement will, when issued
          and delivered against payment therefor as contemplated by the
          Registration Statement and the form of Underwriting Agreement (the
          "Underwriting Agreement") by and among the Company, Goldman, Sachs &  
          Co., Morgan Stanley & Co. Incorporated, Smith Barney Inc. and William
          Blair & Company, L.L.C. and certain shareholders of the Company (the
          "Selling Shareholders") named in Schedule II thereto, filed as
          Exhibit 1.01 and the International Underwriting Agreement (the
          "International Underwriting Agreement") by and among the Company,
          Goldman Sachs International, Morgan Stanley & Co. International
          Limited, Smith Barney Inc. and William Blair & Company, L.L.C. and the
          Selling Shareholders named in Schedule II thereto filed as Exhibit
          1.02 in the Registration Statement (the Underwriting Agreement and
          the International Underwriting Agreement are collectively referred to
          as the "Underwriting Agreements"), be validly issued, fully paid and
          nonassessable.

      2.  The 3,440,000 shares of Common Stock of the Company owned by the
          Selling Shareholders which are being registered pursuant to the
          Registration Statement are validly issued, fully paid and
          nonassessable.

      The opinions expressed herein do not extend to compliance with state and
federal securities laws relating to the sale of these securities.

      We hereby consent to the reference to our firm under the heading
"Validity of Shares" in the Registration Statement and in any registration
statement that may be filed by the Company pursuant to Rule 462(b) promulgated
under the Act and to the filing of this opinion as Exhibit 5.01 to the
Registration Statement.  Such consent shall not be deemed to be an admission
that this firm is within the category of persons whose consent is required
under Section 7 of the Act, or the regulations promulgated by the Commission
pursuant to such Act.

      This opinion is rendered solely for your benefit in connection with the
transactions described above.  This opinion may not be used or relied upon by
any other person without our prior written consent.



                                      Sincerely yours,

                                      SMITH, ANDERSON, BLOUNT, DORSETT,
                                         MITCHELL & JERNIGAN, L.L.P.
