ITEM 5.  OTHER EVENTS.

     On October 6, 1996, Quintiles Transnational Corp., a North Carolina
corporation ("Quintiles"), Innovex Limited, a company organized under the laws
of England and Wales ("Innovex"), and the shareholders of Innovex, signed a
definitive agreement, dated as of October 4, 1996 (the "Exchange Agreement"), by
which Quintiles will exchange up to 10 million shares of its common stock, par
value $.01 per share ("Common Stock"), for all of the outstanding ordinary
shares and cumulative participating preferred ordinary shares ("Innovex Shares")
of Innovex (the "Exchange").

     The Exchange Agreement provides that, following the performance and
fulfillment of all covenants, conditions and obligations to the Exchange (other
than those waived in accordance with the terms of the Exchange Agreement),
Quintiles will acquire all of the outstanding Innovex Shares from the
shareholders of Innovex and Innovex will become a wholly-owned subsidiary of
Quintiles and continue its existence as a company under the laws of the United
Kingdom.  On the Closing Date, for an aggregate amount of approximately $60
million (the source of which is expected to be Quintiles' working capital),
Quintiles would also (i) purchase all outstanding Innovex cumulative redeemable
preference shares from the holders of such shares for L1.00 each, plus accrued
and unpaid dividends thereon and (ii) advance cash to Innovex sufficient to
satisfy certain indebtedness of Innovex.  The Exchange will be effected by the
delivery at Closing by the Innovex Shareholders of duly executed stock transfer
forms in respect of all of their Innovex Shares together with certificates
representing such shares in exchange for shares of Quintiles Common Stock.  The
Exchange will become effective at the date and time specified in the Exchange
Agreement (the "Closing Date").

     It is the intention of the parties to consummate the Exchange and the other
transactions contemplated by the Exchange Agreement (the "Closing") as soon as
possible following approval of the issuance of the Exchange Shares by the
shareholders of Quintiles and satisfaction of all covenants and conditions to
the parties' respective obligations to consummate the Exchange (or, to the
extent permitted, waiver thereof) at such other time as designated in writing by
Quintiles and Innovex.

     Pursuant to the Exchange Agreement, Quintiles has agreed to substitute
options to acquire Innovex ordinary shares ("Innovex Options") for options to
acquire shares of Quintiles Common Stock ("Quintiles Options").  On the Closing
Date, each Innovex Option will be cancelled and a new Quintiles Option to
acquire shares of Quintiles Common Stock will be substituted therefor.  The
exercise price for any Quintiles Options so received will equal the exercise
price of the Innovex Options exchanged for such Quintiles Options divided by
the exchange ratio of .07981 applicable in the Exchange.  Each Quintiles Option
will otherwise be subject to equivalent terms and conditions as apply to the
corresponding Innovex Option.  The total number of shares of Quintiles Common
Stock issuable in the Exchange and upon exercise of the substituted options is
10 million.

     On the Closing Date and pursuant to an escrow agreement among the parties,
two and one-half percent of the total number of shares of Quintiles Common Stock
to be issued in the Exchange will be delivered pro rata by the Innovex
shareholders to the escrow agent under the escrow agreement to be held by such
escrow agent for the purpose of securing the obligations of the Innovex
shareholders pursuant to the indemnification provisions of the Exchange
Agreement.

     In addition, on the Closing Date, Barrie S. Haigh, currently the Chairman
of Innovex will execute an employment agreement with Quintiles on terms similar
to his existing service agreement and also providing for a noncompetition
covenant restricting Mr. Haigh for a period ending on the date he reaches age 65
or, if later, two years after his employment with Quintiles ends.  In addition,
certain other senior executive officers of Innovex will execute employment
agreements with Quintiles which will include terms satisfactory to the parties
as well as noncompetition covenants.  Mr. Haigh and Paul Knott, currently Group
Finance Director of Innovex, will also be appointed to the Board of Directors of
Quintiles.

     The shares of Quintiles Common Stock to be received by the shareholders of
Innovex in the exchange will be issued by Quintiles without registration under
the Securities Act of 1933, as amended (the "Securities Act"), pursuant to the
exemptions from registration contained in Section 4(2) of, and



                                      -2-


<PAGE>   3
Regulation S under, the Securities Act.  As a result, the acquired shares may be
transferred only pursuant to an effective registration statement under the
Securities Act or pursuant to an exemption from registration.  Quintiles has
agreed to provide the Innovex Shareholders with certain rights, which are
subject to market conditions and other customary limitations, to have the
acquired shares registered under the Securities Act pursuant to a Registration
Rights Agreement, the form of which has been attached to the Exchange Agreement.
Under the Registration Rights Agreement, which would be executed when the
Exchange is consummated, Quintiles has (i) agreed to file a registration
statement for an underwritten offering to include up to 2.7 million of the
acquired shares and granted to the Innovex shareholders rights to demand
registration until an aggregate of 2.7 million shares are sold, (ii) agreed to
file a shelf registration statement to allow the Innovex shareholders to
register for resale in the market up to 500,000 shares every 90 days for a
period of approximately three years and (iii) granted rights to the Innovex
shareholders to participate with Quintiles in certain underwritten offerings
that Quintiles may file over the next approximately three years.  The rights
granted to the Innovex shareholders terminate when, among other things, the
acquired shares may be sold within the limitations set forth in Rule 144 under
the Securities Act or if the holder thereof transfers the acquired shares to an
ineligible person.

     On October 7, 1996, the Registrant issued a press release regarding the
Exchange.  The text of the press release is as follows:

        QUINTILES SIGNS DEFINITIVE SHARE EXCHANGE AGREEMENT WITH INNOVEX

          RESEARCH TRIANGLE PARK, NC - October 7, 1996 - Quintiles Transnational
     Corp. (Nasdaq: QTRN) announced today the signing of a definitive share
     exchange agreement with the shareholders of Innovex Ltd., an international
     contract pharmaceutical organization based in Marlow, United Kingdom.  If
     the agreement is completed, Quintiles would have the broadest array of
     services to meet the needs of the pharmaceutical and other healthcare
     sectors.  With the Innovex alliance, Quintiles could expand its
     full-service capabilities beyond development of drugs and offer its
     customers sales and marketing services. This combination would create the
     world's first and largest full-service contract pharmaceutical and
     healthcare company.

          The agreement calls for an exchange of all of Innovex stock for 10
     million shares of Quintiles stock in a pooling of interests transaction. If
     the deal closes, Quintiles plans to retire approximately $60 million of
     existing Innovex obligations.  Completion of the agreement, which is
     subject to Quintiles shareholder approval and regulatory approval, is
     expected later this year.

          Innovex is believed to be the largest privately held contract
     pharmaceutical organization in the world with more than 3,200 employees in
     the U.K., continental Europe and the United States.  The company's core
     competencies focus on supplementing the sales and marketing of drugs for
     many of the leading 25 pharmaceutical companies on a global basis.
     Innovex's clinical research and contract-selling activities are
     concentrated during the peri-marketing phase of two years pre- and two
     years post-regulatory approval. Innovex's expertise would be highly
     synergistic with and complementary to Quintiles' global clinical research
     and data management capabilities.  With Innovex, Quintiles could supplement
     its strong revenue growth derived from its core development business with a
     new avenue of strong revenue growth derived from sales and marketing.

          Innovex recorded net revenue of $129.1 million for its fiscal year
     ending March 31, 1996, and $80.4 million for its year ending March 31,
     1995, a 61 percent growth rate.  Quintiles reported net revenue of $156.4
     million for its fiscal year ending December 31, 1995, and net revenue of
     $90.1 million for the year ending December 31, 1994, a 74 percent growth
     rate.  Quintiles' annual growth rate has averaged more than 50 percent for
     the last five years.  The proposed combination of the two companies, both
     of which have excellent profit records,



                                      -3-
<PAGE>   4
     is expected to be accretive to earnings per share by approximately 5 to 7
     cents for 1997.  Quintiles expects to take a one-time charge related to the
     transaction; the amount has not been determined.

          "This is fundamentally a growth transaction because of the
     opportunities that exist in pharmaceutical outsourcing and healthcare
     today," said Quintiles Transnational Corp. Chairman and CEO Dennis
     Gillings, Ph.D. "We aim to be aggressive about competing for market share
     and we believe we are ahead of our competition.  The combined company of
     Quintiles and Innovex, if the deal is completed, would be the largest and
     fastest-growing services company in this arena.  We will provide a unique
     configuration of services to the pharmaceutical and healthcare sectors,
     comprising a broader spectrum than any other service company."

          With Innovex, the integration of the development and promotion
     functions allows Quintiles to help its clients achieve and maximize faster
     the keys to the success of a drug -- including superior claims, broader
     indications and improved convenience.  The coordination of delivery and
     promotion also allows Quintiles to integrate better the data generated from
     the two functions toward the formation of outcomes research and disease
     management initiatives.

          Senior management at both companies have enthusiastically endorsed
     what Innovex Chairman Barrie Haigh called "the unbeatable mix of Quintiles'
     scientific strength with Innovex's global commercialization strengths -- a
     mix of enormous benefit to our customers.  Our sales and marketing services
     have been the fastest-growing segment of our business.  Together with
     Quintiles' full-service systems, we would open up exciting new business
     development avenues."

          The combined company would be chaired by Dennis Gillings who would
     also continue as Chief Executive Officer.  Quintiles' new company structure
     would have three divisions, all of which would report to President and
     Chief Operating Officer Santo J. Costa.  Current Quintiles Chief Financial
     officer Rachel Selisker would serve in that role for the combined company.
     Barrie Haigh would serve as Vice Chairman and would oversee the business
     development function for all divisions.  Haigh and current Innovex Group
     Finance Director Paul Knott are expected to be named to the Quintiles
     Transnational Corp. Board of Directors.

          As part of the proposed transaction, the company is expected to enter
     into employment and non-competition agreements with Haigh, Knott, and
     certain other Innovex management.  The Innovex shareholders will receive
     unregistered shares at closing but will receive certain registration rights
     commencing during the first quarter of 1997, subject to market conditions
     and other customary limitations.

          Quintiles recently announced the signing of a definitive agreement to
     acquire BRI International, a contract research organization headquartered
     in Arlington, VA, with 445 employees.  BRI's net revenues for the fiscal
     years ending November 30, 1995, and November 30, 1994, were respectively,
     $42.6 million and $28.6 million, reflecting a 49 percent growth rate.
     Among its other services, BRI offers the world's largest outsourcing
     capability to the medical device industry.  The transaction is expected to
     close later this year and could add up to 5 cents to Quintiles' earnings
     per share in 1997.

          Quintiles' worldwide services encompass healthcare product development
     and information management.  Quintiles offers globally integrated research
     and development and strategic consulting services to pharmaceutical,
     biotechnology, medical device, and healthcare management industries, as
     well as to local and national governments.  The company's core competencies
     include clinical research and data management, and consulting on healthcare
     policy,


                                     -4-

     disease management and regulatory issues.  Quintiles is headquartered near
     Research Triangle Park, NC, and has 41 operating units in 19 countries.

          Information in this press release contains "forward-looking
     statements."  These statements involve risks and uncertainties that could
     cause actual results to differ materially, including without limitation,
     whether the proposed share exchanges actually occur, the ability of the
     combined businesses to be integrated with Quintiles' current operations,
     actual operation performance, the ability to maintain large client
     contracts or to enter into new contracts, and the actual costs of the
     combining of the businesses.

                 NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS
 
NOTE 1  BASIS OF PRESENTATION
 
     The accompanying Condensed Consolidated Financial Statements present the
financial position and results of operations of Innovex PLC and its subsidiaries
(hereafter referred to as the "Group") and have been prepared in accordance with
generally accepted accounting principles in the United Kingdom ("U.K. GAAP")
which differ in certain significant respects from those applicable in the United
States ("U.S. GAAP"). See Note 27 of Notes to the Combined Financial Statements
included elsewhere in this Prospectus for a discussion of the principal
differences between U.K. GAAP and U.S. GAAP affecting the Group.
 
     The interim financial information included in these Condensed Consolidated
Financial Statements is unaudited but reflects all adjustments (consisting only
of normal recurring accruals) which are, in the opinion of management, necessary
for a fair presentation of the results for the interim periods presented. The
interim Condensed Consolidated Financial Statements should be read in
conjunction with the Combined Financial Statements and notes thereto included
elsewhere in this Prospectus.
 
     Solely for the convenience of the reader, the Condensed Consolidated
Financial Statements as at and for the three-month period ended June 30, 1996
have been translated from pound sterling amounts into U.S. dollars using the
June 28, 1996 Noon Buying Rate in New York City for cable transfers in pound
sterling, as certified for customs purposes by the Federal Reserve Bank of New
York of L1.00 = U.S.$1.5529. Interim results for the three month period ended
June 30, 1996 are not necessarily indicative of the results for the full year.
 
     The provision for income taxes in the Condensed Consolidated Income
Statements is based upon management's best estimate of the effective tax rate to
be applicable for the entire year and taking into account the anticipated impact
of foreign tax rates, available tax loss carry forwards and other relevant tax
issues in the jurisdictions in which the Group operates.
 
NOTE 2  REORGANIZATION
 
     On April 3, 1996, Innovex PLC and the former holding company of the Innovex
group, Innovex Holdings Limited completed a series of transactions designed to
establish Innovex PLC as the holding company of the Innovex Group. The Company
and Innovex Holdings Limited entered into an Exchange Agreement, dated April 3,
1996, pursuant to which Innovex PLC, the entire outstanding share capital of
which consisted of two thousand ordinary shares owned by Mr. Haigh and Dr.
Knott, agreed to acquire the entire issued share capital of Innovex Holdings
Limited in exchange for 72,631,305 newly issued ordinary shares of 0.1p each,
14,285,720 cumulative participating preferred ordinary shares of 0.1p each (the
"preferred shares"), L16,980,000 of 6.03125% vendor guaranteed loan notes, due
on or about October 3, 1996, of Innovex PLC, and L1,620,000 of cash. Innovex
PLC's performance of its obligations under the loan notes was guaranteed by
Lloyds Bank pursuant to a Facilities Agreement, dated April 3, 1996, which
provides for a L15,000,000 secured guarantee and term-loan facility and a
L2,000,000 cash-backed guarantee facility. In connection with these
transactions, Innovex PLC also entered into a L3,000,000 overdraft facility,
dated April 3, 1996, with Lloyds Bank.
 
     Pursuant to an Investment Agreement, dated April 3, 1996, Innovex PLC
issued 28,533,345 additional preferred shares and created and issued 11,000,000
7.5% cumulative redeemable preference shares of 1.0p each ("the preference
shares"), ranking senior to the preferred shares, and L6,900,000 aggregate
principal amount of 8.70% loan stock. The loan stock issued had a nominal value
of L10,200,000 and an effective interest rate of 14.85%.
 
     The preferred shares rank for a cumulative participating net dividend in
respect of the year ending March 31, 2000 and subsequent years. The amount of
the dividend will be equal to a percentage of profit after

tax, where the percentage equals one third of the number of preferred shares
outstanding during the relevant year as a percent of the total number of
ordinary shares and preferred shares outstanding during such years. The
preference shares are redeemable by Innovex PLC on or before March 31, 2004.
 
     These transactions are considered as having no effect on the basis of
accounting for assets and liabilities and are viewed as having occurred among
members of a commonly controlled group in connection with a proposed
capital-raising transaction after which the controlling shareholder retained
control. Further details are given in Note 23 of Notes to the Combined Financial
Statements.
 
     In August, the Company's share capital was consolidated at the ratio of 50
then-existing ordinary shares, nominal value 0.1 pence per ordinary share, for
each new ordinary share, nominal value 5 pence per ordinary share. To the extent
the number of ordinary shares held by any shareholder was not divisible by 50,
new ordinary shares were issued to such shareholder to make the number of
ordinary shares sold by such shareholder divisible by 50. Immediately following
this consolidation of its ordinary share capital, the Company made a bonus issue
of 49 new ordinary shares for each existing ordinary share.
 
NOTE 3  SUMMARY OF DIFFERENCES BETWEEN U.K. GAAP AND U.S. GAAP
 
     The Group's condensed consolidated financial statements are prepared in
U.K. GAAP, which differ in certain significant respects from U.S. GAAP. The
following is a summary of the adjustments to net income for the three months
ended June 30, 1995 and 1996 and shareholders' equity as at June 30, 1996 that
would have been required if U.S. GAAP had been applied instead of U.K. GAAP in
the preparation of the condensed consolidated financial statements.

                          INDEPENDENT AUDITORS' REPORT
 
                 To the Shareholders and Board of Directors of
                    Innovex PLC and Innovex Holdings Limited
 
     We have audited the combined balance sheets of the Innovex Companies, which
comprise a combination of Innovex PLC and Innovex Holdings Limited and its
subsidiaries, as at March 31, 1995 and 1996 and the related combined income
statements and statements of cash flows for each of the years in the three-year
period ended March 31, 1996. These combined financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these combined financial statements based on our audits.
 
     We conducted our audits in accordance with auditing standards in the United
Kingdom and the United States of America. 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, amounts and disclosures in the financial statements. An audit also
includes assessing the accounting principles used and significant estimates made
by management as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
     In our opinion, the aforementioned combined financial statements present
fairly, in all material respects, the financial position of the Innovex
Companies, as at March 31, 1995 and 1996 and the results of their operations and
their cash flows for each of the years in the three-year period ended March 31,
1996 in conformity with generally accepted accounting principles in the United
Kingdom.
 
     Generally accepted accounting principles in the United Kingdom vary in
certain significant respects from generally accepted accounting principles in
the United States. Application of generally accepted accounting principles in
the United States would have affected the results of operations and
shareholders' equity as at and for the years ended March 31, 1995 and 1996, to
the extent summarized in Note 27 to the combined financial statements.

                   NOTES TO THE COMBINED FINANCIAL STATEMENTS
 
NOTE 1  SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES
 
     The accompanying Combined Financial Statements present the financial
position and results of operations of Innovex PLC (the "Registrant") and Innovex
Holdings Limited and its subsidiaries, the predecessor entities to Innovex PLC
(see Note 23). Innovex PLC and Innovex Holdings Limited and its subsidiaries are
herein referred to as the "Group" or the "Company". The Combined Financial
Statements have been prepared in accordance with United Kingdom generally
accepted accounting principles ("U.K. GAAP"). These accounting principles vary
in certain significant respects from accounting principles generally accepted in
the United States ("U.S. GAAP"). See Note 27 for a discussion of the principal
differences between U.K. GAAP and U.S. GAAP that affect the Group's combined net
income and shareholders' equity.
 
     Solely for the convenience of the reader, the Combined Financial Statements
as at and for the year ended March 31, 1996 have been translated from pound
sterling amounts into U.S. dollars using the June 28, 1996 Noon Buying Rate in
New York City for cable transfers in pound sterling, as certified for customs
purposes by the Federal Reserve Bank of New York of, L1.00 = U.S.$1.5529.
 
NATURE OF OPERATIONS
 
     The Group is an international contract pharmaceutical organization based in
the United Kingdom, which provides a wide range of contract research and sales
and marketing services to the pharmaceutical industry. The principal places of
business are the United Kingdom, the United States and Germany.
 
     Due to the international nature of the Group's operations, exchange rate
movements give rise to foreign currency translation risk when revenues, costs
and net assets of foreign subsidiaries are converted to sterling. The Group does
not hedge the translation risk arising from the net assets of foreign
subsidiaries.
 
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 of assets and liabilities reported and of
contingent assets and liabilities disclosed at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
BASIS OF PREPARATION
 
     The financial statements have been prepared in accordance with applicable
accounting standards and under the historical cost accounting rules.
 
BASIS OF COMBINATION AND CONSOLIDATION
 
     The Group financial statements reflect the combination of the financial
statements of Innovex PLC and the consolidated financial statements of Innovex
Holdings Limited and all of its subsidiaries. All intercompany transactions have
been eliminated in the consolidation process. These commonly controlled
companies became a consolidated group as a result of a reorganization on April
3, 1996. See Note 23.
 
     Unless otherwise stated, the acquisition method of accounting has been
adopted for businesses acquired. Under this method, the results of subsidiaries
acquired or disposed of in the year are included in the combined income
statement from the date of acquisition or up to the date of disposal. Goodwill,
representing the excess of the fair value of the consideration paid over the
fair value of the separable net assets acquired, is amortized over a period of
20 years to reflect its useful economic life.

            NOTES TO THE COMBINED FINANCIAL STATEMENTS  (CONTINUED)
 
SALES
 
     Net sales represent the amounts (excluding value added tax) derived from
providing goods and services to customers during the year. Net sales exclude
pass through costs which are costs incurred on behalf of and recharged directly
to customers.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Depreciation is provided to write off the cost less the estimated residual
value of property, plant and equipment in equal instalments over their estimated
useful economic lives as follows:
 
<TABLE>
          <S>                                                           <C>
          Leasehold improvements......................................  5 years
          Motor vehicles..............................................  4 years
          Furniture, fittings and equipment...........................  3 to 10 years
          Computer equipment..........................................  3 years
          Freehold buildings..........................................  40 years
</TABLE>
 
     No depreciation is provided on freehold land.
 
INTANGIBLE ASSETS
 
     Intangible assets, other than goodwill, comprise acquired licences to sell
certain pharmaceutical products and trademarks, and are valued at historic cost.
These assets are recorded in the balance sheet as intangible assets and are
amortized over the shorter of their estimated useful lives or licence terms on a
straight-line basis, usually over 3 to 5 years. The directors regularly review
the value of the assets and provision is made for any permanent diminution in
value.
 
     In certain instances Novex Pharma acquires a product licence in exchange
for Innovex services. Novex Pharma acquires the licence from a third party for
an agreed amount. The consideration is settled by Innovex supplying the services
to the third party. Settlement of the purchase price passes between Innovex and
Novex Pharma through the intercompany account.
 
INVENTORIES
 
     Inventories, consisting of finished goods, are stated at the lower of cost
or net realizable value, calculated on a first in, first out basis.
 
REVENUE RECOGNITION
 
     The majority of the Company's revenues are based on the number of days
worked multiplied by a daily rate as established by the contract. Revenues are
recognized as the work is performed. Invoices are raised in accordance with an
agreed billing schedule and, therefore, a short-term timing difference may arise
between the amount invoiced at the period end and the work done. This difference
will either be included in current assets as unbilled accounts receivable, where
the value of work done exceeds the billings, or in the case of contracts where
invoicing exceeds the value of work done, any excess is included in current
liabilities as advance payments received.
 
     The clinical research services include a number of fixed price contracts.
These contracts provide for the payment of additional fees in the event of
changes in the scope, nature, duration or conditions of the project. Profits are
taken only when the outcome of the contract can be foreseen with reasonable
certainty and are calculated on a percentage completion basis normally on the
achievement of agreed milestones. If the

                     (PREDECESSOR ENTITIES TO INNOVEX PLC)
 
            NOTES TO THE COMBINED FINANCIAL STATEMENTS  (CONTINUED)
 
outcome of a contract cannot be foreseen with reasonable certainty, no profit
will be recognized. All losses are provided in full when foreseen.
 
     Each contract includes a billing schedule, and invoices are raised
accordingly. The billing schedules vary between contracts, and billings will
normally continue over the life of the contract. Any difference arising between
the amount billed and the revenue recognized on a particular contract is
included in the balance sheet as unbilled accounts receivable or advance
payments received. Amounts included in unbilled accounts receivable are expected
to be collected within one year and are included within current assets.
 
FOREIGN CURRENCIES
 
     Transactions denominated in foreign currencies are translated at the rate
of exchange prevailing at the date of the transaction. Monetary assets and
liabilities denominated in foreign currencies are translated using the rate of
exchange prevailing at the balance sheet date and the gains or losses arising on
translation are included in the income statement.
 
     On consolidation, the assets and liabilities of overseas subsidiaries are
translated at the closing exchange rates and the statements of income at the
average rates of exchange prevailing during the year. Exchange differences
arising from these translations are taken to retained earnings.
 
LEASES
 
     Where the company enters into a lease which entails taking substantially
all the risks and rewards of ownership of an asset, the lease is treated as a
capital lease. The asset is recorded in the balance sheet as property, plant and
equipment and is depreciated over its estimated useful life or the term of the
lease, whichever is shorter. Future instalments under such leases, net of
finance charges, are included within creditors. Payments are apportioned between
the finance element, which is charged to the income statement and the capital
element, which reduces the outstanding obligation for future instalments.
 
     All other leases are accounted for as operating leases and the rental
charged to the income statement on a straight line basis over the term of the
lease.
 
CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents consist of highly liquid investments that are
readily convertible to known amounts of cash and generally have original
maturities of three months or less, offset by bank overdrafts.
 
POST-EMPLOYMENT BENEFITS
 
     The Group operates a defined contribution pension plan for employees and
executive directors in the United Kingdom. The assets of the plan are held
separately from those of the Group in an independently administered fund. The
amounts charged against income represent the contributions payable to the plan
in respect of the year.
 
     The Group operates an unfunded defined benefit plan for employees in
Germany. Full provision is made in the balance sheet for the pension commitments
and the charge in the income statement reflects the obligations. As is customary
in Germany, the assets of the plan are not held separately from the assets of
the Company, cash contributions are not paid to an external fund and the
benefits are paid directly by the Companies. Appropriate insurance policies have
been arranged for accident and death benefits and to meet the pension
obligations in the event that the Company is unable to do so.

            NOTES TO THE COMBINED FINANCIAL STATEMENTS  (CONTINUED)
 
LOAN STOCK
 
     The finance cost of the loan stock is allocated over their term of the debt
using the effective interest rate method and is calculated as the difference
between the issue proceeds, net of direct issue costs, and the total amount
payable at maturity on the loan stock and cash interest payable.
 
TAXATION
 
     The charge for taxation is based on the income for the year and takes into
account taxation deferred because of timing differences between the treatment of
certain items for taxation and accounting purposes. Provision is made for
deferred taxation only to the extent that there is reasonable evidence that such
deferred taxation will be payable or recoverable in the foreseeable future.
 
     Advance corporation tax ("ACT") recoverable by deduction from future
corporation tax is carried forward within deferred taxation or as ACT
recoverable within current assets.
 
DEFERRED CONSIDERATION PAYABLE
 
     Deferred consideration payable comprises payments in respect of businesses
acquired that are contingent on the future results of the companies acquired.
The amounts included within liabilities represent the maximum expected amount
payable, subject to foreign exchange movements based on forecast results for the
period to March 31, 1997. Adjustments for actual amounts paid are accounted for
in the year of settlement.
 
FOREIGN CURRENCY OPTIONS
 
     Gains and losses on foreign exchange options that are designated and
effective as hedges of firm foreign currency commitments are deferred and
recognized in income or as adjustments of carrying amounts when the hedged
transaction occurs.

NOTE 3  SIGNIFICANT ACQUISITIONS
 
     On April 1, 1993, the Group acquired the entire issued share capital of
Innovex GmbH (Freiburg), the holding company for the Clinical Research

     The total cash consideration is an amount up to 30,214,000 DM
(L12,470,000), of which 9,733,000 DM (L4,017,000) was paid as initial
consideration, 2,001,000 DM (L826,000) was paid on March 31, 1994 and 7,000,000
DM (L3,155,000) was paid on April 3, 1995. As of March 31, 1996, the balance of
11,480,000 DM (L5,094,000) is to be paid as deferred consideration contingent
upon the results of the Clinical Research Foundation group in the period to
March 31, 1997. The pounds sterling equivalents are as at the date of payment
or, when unpaid, the balance sheet date.
 
     On February 1, 1994 the Group acquired the entire issued share capital of
Innovex (Nordic) AB. The acquisition provided clinical research operations in
Sweden. The total cash consideration was up to L1,153,000 of which L550,000 was
paid as initial consideration and the balance of L603,000 was contingent on the
results of Innovex (Nordic) AB in the period to March 31, 1995. The deferred
consideration was paid in instalments up to December 1995.
 
     Goodwill arising on consolidation (representing the excess of the fair
value of the consideration paid over the fair value of the separable net assets
acquired) is amortized over a period of 20 years. At the time of acquisition the
Company evaluated the economic benefit that would be derived from the business
and has amortized the goodwill accordingly.
 
     The directors reassess the estimated useful life of the group's investments
each year.

NOTE 9  POST-EMPLOYMENT BENEFITS
 
     The costs charged for the years ended March 31, 1994, 1995 and 1996 in
respect of the U.K. defined contribution plan represent contributions payable by
the Group to the trust fund and amounted to L560,000, L568,000 and L738,000,
respectively. There were no outstanding or prepaid contributions either at the
beginning or at the end of the year. The pension costs charged for the years
ended March 31, 1994, 1995 and 1996 in respect of other overseas companies
schemes were L151,000, L321,000 and L456,000, respectively.
 
     As explained in the accounting policies set out in Note 1, the Group
operates an unfunded defined benefit plan for employees in Germany. The plan
provides benefits based on final pensionable pay. As is customary in Germany,
assets of the plan are not held separately from the assets of the Company, cash
contributions are not paid to an external trust and the benefits are paid
directly by the Company. The amount of the provision is determined by a
qualified actuary on the basis of annual valuations using the individual entry
age method. The most recent valuation was at an effective date of April 1, 1996,
and the provision has been increased in line with actuarial advice. The
assumptions which have the most significant effect on the results of the
valuation are those relating to the following factors:
 
a)  investment return of 7% per annum compound;
 
b)  increase in pensionable salary at a rate of 5% per annum compound;
 
c)  mortality in accordance with standard tables; and
 
d)  pension increases at a rate of 3% per annum compound.

     The loan stock was issued on April 1, 1993 at a price of L6,000,000, with a
nominal value of L7,950,000. The loan stock matures at various dates from
September 30, 1996 to March 31, 1999. The loan stock has a stated coupon rate of
5% for the period April 1, 1993 to March 31, 1994 and 10% thereafter, with
interest payable on March 31 and September 30 each year. The effective interest
rate of the loan stock is 15.1%.

holding company, Innovex PLC, received proceeds totalling L6,900,000 from the
issuance of new loan stock which were used to repay the loan stock described
above. The allocation of loan stock between current and long term in these
financial statements reflects the maturity of the loan stock as if no redemption

     On June 12, 1995 the Company sub-divided its authorized share capital into
250,000,000 ordinary shares of 0.1p each, by means of a 10-for-1 stock split.
During the year to March 31, 1996, 216,650 A ordinary shares of 0.1p each were
issued at 10p each and 250,000 A ordinary shares of 0.1p were issued at 20p
each. Prior to the stock split, 70,000 A ordinary shares of 1p each were issued
at L1.00 during the year to March 31, 1995. A and B ordinary shares rank equally
for dividends and voting rights. Shareholders who wish to transfer their shares
must first offer them to other A shareholders. There are no such restrictions on
B shareholders.
 
     The Company operates an executive share option scheme which was approved by
the board in 1993. Options granted under the plan give the holder the right to
purchase A ordinary shares at prices not below estimated fair market value at
the date of grant and are exercisable in normal circumstances between December
1996 and September 2004. No compensation expense is recorded in respect of these
options.
 
     Transactions during the three years ended March 31, 1996 are given below.
The numbers of shares and exercise price have been adjusted to reflect the stock
split in June 1995.

NOTE 23  SUBSEQUENT EVENTS: REORGANIZATION
 
     On April 3, 1996, Innovex PLC and the former holding company of the Innovex
group, Innovex Holdings Limited completed a series of transactions designed to
establish Innovex PLC as the holding company of the Innovex Group. The Company
and Innovex Holdings Limited entered into an Exchange Agreement, dated April 3,
1996, pursuant to which Innovex PLC, the entire outstanding share capital of
which consisted of two thousand ordinary shares owned by Mr. Haigh and Dr.
Knott, agreed to acquire the entire issued share capital of Innovex Holdings
Limited in exchange for 72,631,305 newly issued ordinary shares of 0.1p each,
14,285,720 cumulative participating preferred ordinary shares of 0.1p each (the
"preferred shares"), L16,980,000 of 6.03125% vendor guaranteed loan notes, due
on or about October 3, 1996, of Innovex PLC, and L1,620,000 of cash. Innovex
PLC's performance of its obligations under the loan notes was guaranteed by
Lloyds Bank pursuant to a Facilities Agreement, dated April 3, 1996, which
provides for a L15,000,000 secured guarantee and term-loan facility and a
L2,000,000 cash-backed guarantee facility. In connection with these
transactions, Innovex PLC also entered into a L3,000,000 overdraft facility,
dated April 3, 1996, with Lloyds Bank.

                     (PREDECESSOR ENTITIES TO INNOVEX PLC)
 
            NOTES TO THE COMBINED FINANCIAL STATEMENTS  (CONTINUED)
 
     Prior to the April Reorganization, the outstanding share capital of Innovex
PLC consisted of 2,000 Ordinary Shares owned by Mr. Haigh and Dr. Knott. Prior
to the April Reorganization, Innovex PLC conducted no business activities, had
no material assets or liabilities, and had no relationship with Innovex Holdings
Limited beyond the common ownership by shareholders of Innovex Holdings Limited.
 
     Prior to the April Reorganization, the share capital of Innovex Holdings
Limited consisted of A Ordinary Shares and B Ordinary Shares. As an intermediate
step to the insertion of the Company as the new holding company, the share
capital of Innovex Holdings Limited was modified by redesignating the B Ordinary
Shares as A Ordinary Shares and issuing new Ordinary Shares, par value $.0001
per share (the "Dollar Shares") to holders of A Ordinary Shares in proportion to
their existing ownership interests. Immediately prior to the performance of the
Exchange Agreement described below, the outstanding share capital of Innovex
Holdings Limited, which consisted entirely of A Ordinary Shares and Dollar
Shares, was owned by the Principal Shareholder (approximately 85%), HSBC,
Lloyds, MSS Nominees Limited, General Accident Executor and Trustee Company
Limited and The Venture Catalysts Limited (collectively, the "Investors")
(approximately 10%) and by various members of management (the "Management
Investors") (approximately 5%).
 
     To enable the Principal Shareholder to realize a portion of its investment
in the Company, the Company entered into an Investment Agreement, dated April 3,
1996 (the "Investment Agreement") between itself, Innovex Holdings Limited, the
Principal Investor and certain of the Management Investors. Pursuant to the
Investment Agreement, Innovex PLC issued 28,533,345 additional preferred shares
and created and issued 11,000,000 7.5% cumulative redeemable preference shares
of 1.0p each ("the preference shares"), ranking senior to the preferred shares,
and L6,900,000 aggregate principal amount of 8.70% loan stock. The loan stock
issued had a nominal value of L10,200,000 and an effective interest rate of
14.85%.
 
     Upon the completion of these transactions, HSBC owned approximately 58% of
the Preferred Shares, 43% of the Preference Shares and 11% of the Loan Stock.
Lloyds owned 12% of the Preferred Shares, 11% of the Preference Shares and 11%
of the Loan Stock. The remaining Preferred Shares, Preference Shares and Loan
Stock were distributed among MSS Nominees Limited, General Accident Executor and
Trustee Company Limited and The Venture Catalysts Limited. The Ordinary Shares
of the Company continued to be owned entirely by the Principal Shareholder
(approximately 94%) and the Management Investors (approximately 6%).
 
     The preferred shares rank for a cumulative participating net dividend in
respect of the year ending March 31, 2000 and subsequent years. The amount of
the dividend will be equal to a percentage of profit after tax, where the
percentage equals one third of the number of preferred shares outstanding during
the relevant year as a percent of the total number of ordinary shares and
preferred shares outstanding during such years. The preference shares are
redeemable by March 31, 2004.

     Interest rate swap agreements that are designated as a hedge of a debt
obligation are accounted for on an accruals basis. That is, the interest payable
and interest receivable under the agreements are accrued and recorded as an
adjustment to the interest expense of the designated liability.
 
     Amounts due from or payable to the counterparties of interest rate swaps
are recorded on an accruals basis at each reporting date based on amounts
computed by reference to the respective agreements.

     In August, the Company's share capital was consolidated at the ratio of 50
then existing ordinary shares, nominal value 0.1 pence per ordinary share, for
each new ordinary share, nominal value 5 pence per ordinary share. To the extent
the number of ordinary shares held by any shareholder was not divisible by 50,
new ordinary shares were issued to such shareholder to make the number of
ordinary shares sold by such shareholder divisible by 50. Immediately following
this consolidation of its ordinary share capital, the Company made a bonus issue
of 49 new ordinary shares for each existing ordinary share.

NOTE 25  FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
 
     A substantial portion of the Group's sales are derived from customers
located outside the United Kingdom. In addition, a portion of the Group's
shareholders' equity is represented by the net assets of foreign subsidiaries.
The Group's operations are conducted in several countries outside of the United
Kingdom. Because of the high proportion of international activity, the Group's
income is exposed to exchange rate fluctuations. Risks of two kinds arise as a
result: a transaction risk (the risk that currency fluctuations will have a
negative effect on the value of the Group's commercial cash flows in various
currencies), and a translation risk (the risk of adverse currency fluctuations
in the translation of foreign operations and foreign assets and liabilities into
pound sterling for the Group's combined financial statements).
 
NOTIONAL AMOUNTS AND CREDIT EXPOSURE
 
     The notional amounts of off-balance sheet financial instruments presented
in this Note and Note 23 represent face or contractual amounts and thus are not
a measure of the exposure of the Group through its use of such financial
instruments. The actual amounts exchanged are calculated on the basis of the
notional amounts and the other terms of the financial instruments which relate
to interest rates or exchange rates.
 
     The Group is exposed to credit-related losses in the event that
counterparties to the off-balance sheet financial instruments do not perform
according to the terms of the contract. In the opinion of management, the
counterparties to the financial instruments are creditworthy parties and the
Group does not expect any significant loss to result from non-performance.
 
FOREIGN CURRENCY RISK MANAGEMENT
 
     At March 31, 1995 and 1996, net assets of foreign subsidiaries denominated
in currencies other than pounds sterling amounted to L1,256,000 and L1,032,000,
respectively. The Group does not use financial instruments to hedge the
translation risk arising from the net assets of foreign subsidiaries.
 
     In order to reduce the foreign currency transaction risk of adverse effects
on the net payment flow in foreign currencies, firmly anticipated future cash
flows are hedged with forward exchange contracts or currency options.
 
     The Group generally hedges its net cash flows of firm sales contracts over
a period not exceeding the anticipated duration of such contracts. Gains and
losses on forward exchange contracts designed to protect such future
transactions are deferred and are reported as adjustments to net sales and
purchases in the Combined Income Statements in the period intended to be covered
by the hedged transactions.

            NOTES TO THE COMBINED FINANCIAL STATEMENTS  (CONTINUED)
 
     During fiscal 1996, the Group entered into an agreement, at a cost of
L41,000, with a financial institution whereby the Group has the right to
exchange up to a maximum of 3,300,000 Deutsche-marks (DM) into pounds sterling
at an exchange rate of DM 2.22 = L1.00. The contracts expire in June 1996. At
March 31, 1996, the Group had exchanged approximately DM 2,000,000 under this
contract with DM 1,300,000 available for exchange under the contract.
 
CONCENTRATIONS OF CREDIT RISK
 
     Credit risk represents the accounting loss that would be recognized at each
reporting date if counterparties to contracts failed to perform as agreed. The
Group has a limited credit risk exposure on its off-balance sheet financial
instruments. The Group does not have a significant exposure to any individual
customer or counterparty.
 
NOTE 26  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     SFAS No. 107, "Disclosures about Fair Values of Financial Instruments,"
requires the disclosure of estimated fair values for all financial instruments,
both on-and off-balance sheet, for which it is practicable to estimate fair
value. The Group has used a variety of methods and assumptions which were based
on market conditions and risks existing at the time to estimate the fair value
of the Group's financial instruments at March 31, 1995 and 1996. For certain
instruments, including cash and cash equivalents, accounts payable and accruals
and short-term debt, it was assumed that the carrying amount approximated fair
value due to the short maturity of those instruments. Techniques, such as
estimated discounted cash flows or replacement cost have been used to determine
fair value for the remaining financial instruments. The estimated fair value of
the Group's off-balance sheet financial instruments is primarily based on
settlement values. These values represent the estimated amount that would be
received or paid to replace the contract taking into consideration the current
credit worthiness of the counterparties and current foreign currency exchange
rates.

</TABLE>
 
     Under U.S. GAAP, cumulative exchange adjustments charged against, or
credited to, the retained surplus/(accumulated deficit) are separately
identified. This does not result in any difference between total shareholders'
equity under U.K. GAAP and U.S. GAAP.
 
     Those differences which have a material effect on combined net income and
shareholders' equity are as follows:
 
(A) DEFERRED CONSIDERATION PAYABLE ON ACQUISITIONS:
 
     Under U.K. GAAP, purchase consideration which is contingent on future
events is recognized at the time of the acquisition on a best estimate basis.
Revised estimates would be made in subsequent years, with the cost of
acquisition and goodwill being adjusted, until the ultimate outcome is known.
 
     Under U.S. GAAP, contingent consideration is recorded when the contingency
is resolved and the consideration becomes payable or the outcome of the
contingency is determinable beyond a reasonable doubt. This may result in later
recognition than under U.K. GAAP, both of the contingent consideration and the
associated goodwill.

            NOTES TO THE COMBINED FINANCIAL STATEMENTS  (CONTINUED)
 
     Where goodwill and deferred consideration are denominated in a foreign
currency, later recognition of these items under U.S. GAAP may result in changes
to cumulative foreign exchange adjustments.
 
(B) PENSIONS:
 
     The Group operates a defined contribution pension plan for employees and
executive directors in the U.K. The assets of the plan are held separately from
those of the group in an independently administered fund. The amounts charged
against income represent the contributions payable to the plan in respect of the
year.
 
     The Group operates an unfunded defined benefit plan for employees in
Germany. Full provision is made in the balance sheet for the pension commitments
and the charge in the income statement reflects the obligations. As is customary
in Germany, the assets of the plan are not held separately from the companies'
assets: cash contributions are not paid to an external fund and the benefits are
paid directly by the companies. Appropriate insurance policies have been
arranged for accident and death benefits and to meet the pension obligations in
the event that the companies are unable to do so.
 
     Under U.S. GAAP, determination of pension expense for defined benefit
schemes is made in accordance with SFAS No. 87 "Employers' Accounting for
Pensions". SFAS No. 87 is more prescriptive than U.K. GAAP in that it requires
the use of a specific actuarial method (the projected unit credit method).
 
(C) DEFERRED TAXATION:
 
     Under U.K. GAAP the charge for taxation is based on the income for the year
and takes into account taxation deferred because of timing differences between
the treatment of certain items for taxation and accounting purposes. Provision
is made for deferred taxation only to the extent that there is reasonable
evidence that such deferred taxation will be payable or recoverable in the
foreseeable future.
 
     Under U.S. GAAP, deferred taxes are required to be recorded on differences
between the book basis and the tax basis for all assets and liabilities.
Deferred tax liabilities are recognized regardless of the timing of reversal of
such amounts and deferred tax assets are reduced by a valuation allowance to the
amount that is "more likely than not" to be realised.
 
(D) VACATION PAY ACCRUAL:
 
     Under U.K. GAAP, there is no requirement to accrue a liability for
employees' compensation for future paid absences.
 
     Under U.S. GAAP, an employer shall accrue a liability for employees'
compensation for future absences if certain conditions are met.
 
(E) LOAN STOCK PAYABLE:
 
     Under U.K. GAAP, the finance and direct issue costs in respect of loan
stock payable are allocated using a constant interest rate over the term of the
loan stock. Under U.K. GAAP, the term of the loan stock is determined to be the
period up to the earliest, commercially practical redemption date.
 
     Under U.S. GAAP, the term of the loan stock is determined in accordance
with the borrowers plans, intent and ability to service the debt. Therefore, the
annual finance costs reallocated to the loan stock may be different.

            NOTES TO THE COMBINED FINANCIAL STATEMENTS  (CONTINUED)
 
(F) CLASSIFICATION DIFFERENCES:
 
Current assets:
 
     Current assets under U.K. GAAP include a deferred tax asset of L1,000,000
and L1,542,000 in the years ended March 31, 1995 and 1996, respectively which
under U.S. GAAP would be reclassified as a non-current asset.
 
Loan stock:
 
     Under U.K. GAAP, unamortized issue costs are deducted from the carrying
value of the loan stock whereas under U.S. GAAP, unamortized issue costs are
shown separately as deferred charges in the balance sheet.
 
Borrowings:
 
     Borrowings under U.K. GAAP are classified according to the maturity of the
financial instrument, while under U.S. GAAP, certain borrowings would be
classified according to the maturity of the available back-up facility. Included
within current liabilities is an amount of L2,300,000 in respect of loan stock
which under U.S. GAAP would be reclassified as non-current to reflect the
replacement borrowing.
 
     The Company had the ability and the intent at the balance sheet date to
redeem the loan stock and replace it with long-term loan stock, the terms of
which are outlined in Note 23.
 
Provisions for liabilities and charges:
 
     Provisions for liabilities and charges under U.K. GAAP include amounts due
within one year of L390,000 (1995: L184,000) which would be reclassified to
current liabilities under U.S. GAAP.
 
Property, plant and equipment:
 
     Property, plant and equipment under U.K. GAAP include an amount of L521,000
(1995: L303,000) in respect of the net book value of capitalized software which
under U.S. GAAP would be reclassified as an intangible asset.
 
Income tax
 
     Income tax has been provided on the U.S. GAAP adjustments made in respect
of vacation pay and loan stock at a rate of 33% in respect of the U.K. companies
and 53% in respect of the German companies.
 
NOTE 28  ADDITIONAL U.S. GAAP DISCLOSURES
 
(A) CASH FLOWS
 
     Under U.K. GAAP, the Group complies with Financial Reporting Standard 1 --
"Cash Flow Statements" (FRS 1). Its objective and principles are similar to
those set out in SFAS No. 95 "Statement of Cash Flows". The principal difference
between the standards is in respect of classification. Under FRS 1, the Group
presents its cash flows for (a) operating activities; (b) returns on investments
and servicing of finance; (c) taxation; (d) investing activities; and (e)
financing activities. SFAS No. 95 requires only three categories of cash flow
activity (a) operating; (b) investing; and (c) financing.
 
     Cash flows arising from taxation and returns on investments and servicing
of finance under FRS 1 would, with the exception of dividends paid, be included
as operating activities under SFAS No. 95; dividend

payments would be included as a financing activity under SFAS No. 95. In
addition, under FRS 1, cash and cash equivalents include short term borrowings
with original maturities of less than 90 days. SFAS No. 95 requires movements on
such short term borrowings to be included in financing activities.
 
     A summarized combined cash flow under U.S. GAAP is as follows:

</TABLE>
 
     The deferred tax asset is higher under U.S. GAAP than under U.K. GAAP due
to:
 
     (1)  U.K. GAAP being more restrictive of the recognition of tax loss carry
        forwards as a deferred tax asset
 
     (2)  the deferred tax effect of the U.S. GAAP adjustments in respect of
        vacation pay
 
     (3)  the recognition of a deferred tax asset, for U.S. GAAP purposes, on
        the pension provision. No deferred tax asset is recorded under U.K. GAAP
        because it is not expected that an asset will be realised in the
        foreseeable future.
 
(D) ACCOUNTING STANDARDS ISSUED BUT NOT YET ADOPTED
 
     In March 1995, the FASB issued Statement of Financial Accounting Standard
No. 121, "Accounting for the Impairment of Long-Lived Assets and for LongLived
Assets to be disposed of" ("SFAS No. 121"). This statement establishes
accounting standards for the impairment of long-lived assets, and for long-lived
assets and certain intangibles to be disposed of. The Group is required to first
comply with the requirements of SFAS No. 121 in its 1997 financial statements.
The provisions of SFAS 121 are consistent in all material respects with the
Company's current practice.
 
     Also during 1995, the FASB issued Statement of Financial Accounting
Standard No. 123, "Accounting for Stock-Based Compensation" which is a standard
that provides an election with respect to accounting for employee share options
and also requires certain additional pro forma disclosures. The Company's
intention is to continue to account for stock based compensation arrangements in
accordance with APB Opinion No. 25 as Statement of Financial Accounting Standard
No. 123, is not expected to have a significant impact on the Company.

for 1996 will be filed following the Company's Annual General Meeting. The
auditors have reported on these accounts. Their reports were unqualified and did
not contain statements under Section 237 (2) or (3) of that Act.
 
     The statutory accounts include certain information related to employee
costs and auditors' remuneration which are not deemed material disclosures in

        UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS OF
                          QUINTILES, BRI AND INNOVEX


The following unaudited pro forma combined condensed financial statements are
presented assuming the Mergers of Quintiles and BRI and Quintiles and Innovex
had occurred at the beginning of each period presented on a pooling of
interests basis.

The unaudited pro forma combined condensed balance sheet reflects the combined
historical balance sheets of Quintiles and Innovex at June 30, 1996 and BRI at
May 31, 1996.  The unaudited pro forma combined condensed statements of
operations for the years ended December 31, 1995, 1994 and 1993, and the six
months ended June 30, 1996 and 1995 reflect historical operating results of
Quintiles for such periods combined with historical operating results of BRI
for the twelve months ended November 30, 1995, 1994 and 1993 (BRI's fiscal
year) and the six months ended May 31, 1996, 1995 and 1994 (Innovex's fiscal
year) and the six months ended June 30, 1996 and June 30, 1995, respectively.

For all applicable periods presented in the pro forma combined condensed
statements of operations, shares used in the computation of earnings per common
and common equivalent share give effect to the appropriate ratios.

The Innovex financial statements have been prepared on a basis of generally
accepted accounting principles (GAAP) in the UK, except for the redeemable
preference shares which have been reclassified from shareholders' equity and
are presented as a separate classification between debt and shareholders'
equity on the June 30, 1996 balance sheet.  The remaining net differences
between UK and US GAAP are immaterial to Innovex's net income and shareholders'
equity for all periods presented.

The pro forma financial statements are not necessarily indicative of the
results that would have been obtained had the Mergers occurred on the dates
indicated.  The pro forma financial statements should be read in conjunction
with the related historical financial statements and notes thereto of
Quintiles, BRI and Innovex incorporated by reference or included hereto,
respectively in this Proxy Statement/Prospectus.

         Notes to Unaudited Pro Forma Combined Condensed Balance Sheet







(1)  BRI's balance sheet is as of May 31, 1996.

(2)  Innovex's financial statements have been prepared on a basis of generally
     accepted accounting principles (GAAP) in the UK, except for the
     redeemable preference shares which have been reclassified from
     shareholders' equity and are presented as a separate classification
     between debt and shareholders' equity.  The remaining net differences
     between UK and US GAAP are immaterial to Innovex's net income and
     shareholders' equity for all periods presented.

(3)  To reduce pro forma retained earnings for non-recurring costs (as 
     currently estimated by management) directly associated with the 
     acquisition of BRI, estimated at $2 million.  

(4)  To reflect the issuance of 1,614,915 shares of Quintiles common stock,
     $.01 par value, in exchange for the 375,448 shares of BRI common stock,
     $0.10 par value, using the agreed upon exchange ratio of 4.3013.

(5)  To reduce pro forma retained earnings for non-recurring costs (as 
     currently estimated by management) directly associated with the acquisition
     of Innovex, estimated at $12 million.

(6)  To reflect the issuance of 10,000,000 shares of Quintiles common stock,
     $.01 par value, in exchange for the outstanding shares of Innovex common
     stock and preferred stock.

(7)  In connection with the transaction, Quintiles will satisfy in full and
     retire approximately $60 million of Innovex's outstanding long-term credit
     facility, which was approximately $49.7 million as of June 30, 1996.  The
     $171,000 of redeemable preference shares will also be redeemed in
     connection with the transaction.

(1)  BRI's income statement is for the six month period ended May 31, 1996.

(2)  Innovex's financial statements have been prepared on a basis of generally
     accepted accounting principles (GAAP) in the UK.  The net differences
     between UK and US GAAP are immaterial to Innovex's net income for the six
     months ended June 30, 1996.

(3)  Pro forma net income per share would have been $0.45 per share for the six
     months ended June 30, 1996 if Innovex had not incurred the $2.3 million of
     non-recurring costs relating to its reorganization and the $2.3 million of
     special pension contributions.

        UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS OF
                            QUINTILES AND INNOVEX


The following unaudited pro forma combined condensed financial statements are
presented assuming the Merger of Quintiles and Innovex had occurred at the
beginning of each period presented on a pooling of interests basis.

The unaudited pro forma combined condensed balance sheet reflects the combined
historical balance sheets of Quintiles and Innovex at June 30, 1996.  The
unaudited pro forma combined condensed statements of operations for the years
ended December 31, 1995, 1994 and 1993, and the six months ended June 30, 1996
and 1995 reflect historical operating results of Quintiles for such periods
combined with historical operating results of Innovex for the twelve months
ended March 31, 1996, 1995 and 1994 (Innovex's fiscal year) and the six months
ended June 30, 1996 and June 30, 1995, respectively.

For all applicable periods presented in the pro form combined condensed
statements of operations, shares used in the computation of earnings per common
and common equivalent share give effect to the appropriate exchange ratio.

The Innovex financial statements have been prepared on a basis of generally
accepted accounting principles (GAAP) in the UK, except for the redeemable
preference shares which have been reclassified from shareholders' equity and
are presented as a separate classification between debt and shareholders'
equity on the June 30, 1996 balance sheet.  The remaining net differences
between UK and US GAAP are immaterial to Innovex's net income and shareholders'
equity for all periods presented.

The pro forma financial statements are not necessarily indicative of the
results that would have been obtained had the Merger occurred on the dates
indicated.  The pro forma financial statements should be read in conjunction
with the related historical financial statements and notes thereto of Quintiles
and Innovex incorporated by reference or included hereto, respectively in this
Proxy Statement/Prospectus.

        Notes to Unaudited Pro Forma Combined Condensed Balance Sheet

(1)     Innovex's financial statements have been prepared on a basis of
        generally accepted accounting principles (GAAP) in the UK, except for
        the redeemable preference shares which have been reclassified from
        shareholders' equity and are presented as a separate classification
        between debt and shareholders' equity.  The remaining net differences
        between UK and US GAAP are immaterial to Innovex's net income and
        shareholders' equity for all periods presented.

(2)     To reduce pro forma retained earnings for non-recurring costs (as
        currently estimated by management) directly associated with the 
        acquisition of Innovex, estimated at $12 million.

(3)     To reflect the issuance of 10,000,000 shares of Quintiles common
        stock, $.01 par value, in exchange for the outstanding shares of 
        Innovex common stock and preferred stock.

(4)     In connection with the transaction, Quintiles will satisfy in full and
        retire approximately $60 million of Innovex's outstanding long-term
        credit facility, which was approximately $49.7 million as of June 30,
        1996.  The  $171,000 of redeemable preference shares will also be
        redeemed in connection with the transaction.

                            SHARE EXCHANGE AGREEMENT

         THIS SHARE EXCHANGE AGREEMENT (this "Agreement") is made and dated as
of October 4, 1996 by and among QUINTILES TRANSNATIONAL CORP., a North Carolina
corporation ("Quintiles"), INNOVEX LIMITED, a company organized under the laws
of England and Wales with limited liability and having the registered number
3127220 ("Innovex"), and the shareholders of Innovex listed in Exhibit A
attached hereto (each a "Shareholder," and collectively the "Shareholders").
Capitalized terms used in this Agreement and not otherwise defined are defined
in Section 9.1 below.

                                  WITNESSETH:

         WHEREAS, the parties hereto desire for Quintiles and Innovex to engage
in, and the Boards of Directors of Quintiles and Innovex have approved, the
exchange of all of Innovex's issued and outstanding ordinary and preferred
ordinary share capital for shares of Common Stock of Quintiles (the "Exchange")
upon the terms and subject to the conditions set forth herein; and

         WHEREAS, the Shareholders are the owners of all of the issued and
outstanding share capital of Innovex;

         NOW, THEREFORE, in consideration of the premises, covenants and
agreements set forth in this Agreement and of other good and valuable
consideration, the receipt and legal sufficiency of which they hereby
acknowledge, and intending to be legally bound hereby, Quintiles, Innovex and
the Shareholders hereby agree as follows:


                                   ARTICLE I
                                  THE EXCHANGE

         1.1.    Exchange of Shares and Related Transactions.  Subject to the
terms and conditions set forth in this Agreement, at the Closing (as defined in
Section 1.4 below):

                 (a)      Exchange of Innovex Shares.  Each Shareholder shall
sell, assign, transfer and deliver to Quintiles (or to an Affiliate of
Quintiles if so directed by Quintiles) the number of Ordinary Shares (if any)
and Preferred Ordinary Shares (if any) (each as defined in Section 2.3 below)
owned by such Shareholder, as set forth opposite such Shareholder's name on
Exhibit A attached hereto (all such Ordinary Shares and Preferred Ordinary
Shares of Innovex, collectively, the "Innovex Shares"), free and clear of all
Encumbrances.  In exchange for the Innovex Shares, Quintiles shall issue and
deliver to each Shareholder the number of shares (less any fractional share,
which shall be eliminated) of Common Stock of Quintiles determined by
multiplying (x) the number of Innovex Shares set forth opposite such
Shareholder's name on Exhibit A hereto as such
<PAGE>   7

Shareholder's total Innovex Shares times (y) the Exchange Ratio determined
according to Section 1.2 below (all such shares of Common Stock of Quintiles so
issued, collectively, the "Quintiles Shares").  Each certificate representing
Innovex Shares shall be accompanied by a stock transfer duly executed by the
Shareholder transferring the same in favor of Quintiles or its designee.
Notwithstanding the foregoing, certificates representing Quintiles Shares to be
issued to Regulation S Participants (as defined in Section 7.2(d) below and
reflected in Exhibit A) shall be delivered on the schedule and in the manner
specified in Section 7.2 below.

                 (b)      Substitution of Quintiles Options for Innovex
Options.  In respect of each outstanding option to purchase Ordinary Shares of
Innovex (as set forth in Schedule 2.3 as "Outstanding Stock Acquisition
Rights"; each an "Innovex Option"), Quintiles shall cause to be granted to the
holder thereof a substitute corresponding option to purchase shares of Common
Stock of Quintiles (each a "Quintiles Option") which shall:  (A) be granted
pursuant to a Quintiles stock option plan with equivalent option terms to the
terms of the Innovex Limited 1996 Unapproved Executive Share Option Scheme; (B)
have term and vesting provisions equivalent to those in such holder's Innovex
Option; (C) be exercisable to purchase the number of shares of Quintiles'
Common Stock (less any fractional share, which shall be eliminated) determined
by multiplying the number of Ordinary Shares of Innovex then purchasable under
such holder's Innovex Option by the Exchange Ratio (as determined in accordance
with Section 1.2 below); and (D) be exercisable at an exercise price per share
of Quintiles' Common Stock determined by dividing the exercise price per
Ordinary Share of Innovex under such holder's Innovex Option by the Exchange
Ratio.  Innovex acknowledges and agrees that the schemes or plans under which
the Innovex Options have been issued provide for the substitution of all
Innovex Options for Quintiles Options as contemplated by this Section 1.1(b)
and that no agreement or any other action of the holders of the Innovex Options
is necessary to effectuate such substitution, and Innovex agrees to take all
actions necessary to cause such substitution.  Upon such substitution of
Innovex Options for Quintiles Options, the Innovex Options shall be deemed
cancelled.

                 (c)      Purchase of Preference Shares.  Each Shareholder
shall sell, assign, transfer and deliver to Quintiles the number of Preference
Shares (if any) (as defined in Section 2.3 below) owned by such Shareholder, as
set forth opposite such Shareholder's name on Exhibit A attached hereto, free
and clear of all Encumbrances.  In exchange for the Preference Shares,
Quintiles shall pay each Shareholder an amount determined by multiplying (x)
the number of Preference Shares set forth opposite such Shareholder's name on
Exhibit A hereto times (y) L.1.00, plus accrued and unpaid dividends to the
Closing Date.  Each certificate representing Preference Shares shall be
accompanied by a stock transfer duly executed by the Shareholder transferring
the same in favor of Quintiles or its designee.

                 (d)      Payment of Certain Liabilities.  Quintiles shall, or
shall cause one of its wholly-owned Subsidiaries to, advance to Innovex, and
Innovex shall accept from Quintiles or such





                                       2
<PAGE>   8

Subsidiary, a sum (the "Cash Payment") sufficient to meet the payments
described in clauses (i) and (ii) of this Section 1.1(d), but in any event not
to exceed L.30 million assuming a Closing Date on or before December 31, 1996.
Contemporaneously with the advance of the Cash Payment, and through application
thereof, Innovex shall:

                          (i)     satisfy in full and retire all of Innovex's
issued and outstanding loan stock at the redemption price thereof plus interest
to the date of redemption less any applicable discount, in accordance with the
terms thereof, such that none shall remain issued or outstanding thereafter;
and

                          (ii)    satisfy in full and retire all of Innovex's
and the Innovex Subsidiaries' outstanding liability under, and terminate,
Innovex's credit facilities with Lloyds Bank, PLC (including payment of all
accrued and unpaid interest and costs associated with the termination of the
related interest rate swap).

                 (e)    Waiver.  On the Closing Date (as defined below), each
of the Shareholders shall be deemed to have waived, without further action, all
of such Shareholders' pre-emptive or similar rights, if any, with respect to
any shares or other securities of Innovex or any Subsidiary.


         1.2.    Exchange Ratio.

                 (a)      Determination.  The Exchange Ratio shall be the
number (rounded to five decimal places) determined by dividing the Total Number
of Quintiles Shares by the Innovex Base Capitalization (each as defined below).
In the event that between the date of this Agreement and the Closing Quintiles
shall change the number of shares of Common Stock of Quintiles that are issued
and outstanding as a result of any stock split, stock dividend or similar
recapitalization, the Exchange Ratio shall be proportionately adjusted
correspondingly.

                 (b)      Definitions.  For purposes of calculating the
Exchange Ratio, the following capitalized terms shall have the respective
meanings set forth below:

                          (i)     "Innovex Base Capitalization" shall mean the
sum of the number of ordinary shares and preferred ordinary shares of Innovex
issued and outstanding as of the Closing Date and the number of ordinary shares
and preferred ordinary shares issuable pursuant to Innovex Options or any other
Stock Acquisition Rights outstanding as of the Closing Date.

                         (ii)     "Total Number of Quintiles Shares" shall mean
ten million (10,000,000).





                                       3
<PAGE>   9

         1.3.    Issuance Into Escrow.  Notwithstanding any provision in this
Agreement to the contrary, upon delivery of the Quintiles Shares to the
Shareholders pursuant to Section 1.1(a), two and one-half (2 1/2%) percent of
the Total Number of Quintiles Shares (the "Escrow Fund") shall be delivered
immediately to the Escrow Agent (as defined in the Escrow Agreement referred to
below), which shall be delivered on a pro rata basis by the Shareholders, to be
held and distributed by the Escrow Agent pursuant to the terms of this
Agreement and the Escrow Agreement substantially in the form attached as
Exhibit B hereto (the "Escrow Agreement").  All such Quintiles Shares shall be
issued in the name of the Escrow Agent, as escrow agent under the Escrow
Agreement.

         1.4.    Closing.  Consummation of the Exchange and the other
transactions contemplated by this Agreement and the other Transaction Documents
(as defined in Section 1.6 below) (the "Closing") shall take place at a
location or locations in London mutually agreed by Quintiles and Innovex (a) as
soon as practicable after the last of the conditions set forth in Articles V
and VI hereof shall be fulfilled or waived in accordance with this Agreement,
but in no event later than the fifth (5th) business day thereafter, or (b) at
such other time and date as Quintiles and Innovex shall designate by written
instrument (the "Closing Date").

         1.5.    Accounting and Tax Treatment.  Quintiles, Innovex and the
Shareholders intend and desire for the transactions contemplated by this
Agreement to qualify for "pooling of interests" treatment for accounting
purposes, as a tax-free rollover pursuant  to United Kingdom tax law  and as a
taxable acquisition of the Innovex Shares by Quintiles for purposes of United
States Federal income tax law.

         1.6.    Transaction Documents.  As used in this Agreement, the term
"Transaction Documents" shall mean, collectively, this Agreement, the Escrow
Agreement, the Employment Agreements (as defined in Section 5.9 below), the
Registration Rights Agreement (as defined in Section 5.12 below) and all
agreements, instruments, certificates and other documents executed or delivered
in accordance with the terms of this Agreement or any other Transaction
Document.

                                   ARTICLE II
         REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERS AND INNOVEX

         Each of the Shareholders designated on Exhibit A as "Management
Shareholders" and Innovex represent and warrant to Quintiles, jointly and
severally (except as to Section 2.1(a), as to which the Shareholders'
(including the Management Shareholders) represent and warrant severally and not
jointly), and agree as follows:

         2.1.    Ownership of Stock.

referred to in Section 1.1(c) the Shareholders shall have no remaining rights
whatsoever therein or pursuant thereto.

         2.2.    Existence.  Innovex is a company duly organized and validly
existing under the Laws of England and Wales.  Innovex has the corporate power
and authority to own, lease and operate its property and conduct its business
as now being conducted.  Innovex is duly qualified to do business in each
jurisdiction in which the character or location of the properties owned or
leased by Innovex or the nature of the business conducted by Innovex makes such
qualification necessary under applicable Laws, except for such failures to be
so qualified or licensed that individually or in the aggregate would not have a
Material Adverse Effect on Innovex and its Subsidiaries taken as a whole.

         2.3.    Share Capital.  The authorized share capital of Innovex is
L.244,015.29, divided into 11,000,000 cumulative redeemable preference shares

ordinary shares of 0.1p each ("Preferred Ordinary Shares"), all of which have
been issued and are outstanding, and 91,196,225 ordinary shares of 0.1p each
("Ordinary Shares"), of which 72,633,305 have been issued and are outstanding.
Innovex's share capital is held and owned by the Shareholders in the amounts
set forth in Exhibit A attached hereto.  Except as set forth in Exhibit A, no

power and authority to enter into and deliver this Agreement and the other
Transaction Documents to which it is a party, to perform its obligations
hereunder and thereunder and to consummate the transactions contemplated hereby
and thereby.  Innovex's execution, delivery and performance of this Agreement
and the other Transaction Documents and Innovex's consummation of the
transactions contemplated hereby and thereby have been duly and validly
authorized by all corporate, director, shareholder and other action required of
Innovex by applicable Law and Innovex's Organizational Documents.  This
Agreement and the other Transaction Documents to which Innovex is a party
constitute the valid and legally binding obligations of Innovex, enforceable
against Innovex in accordance with their respective terms.

         2.5.    Subsidiaries and Investments.

                 (a)      Innovex does not have any Subsidiaries or any equity
or similar interest in any Person except as set forth in Schedule 2.5 attached
hereto.

                 (b)      Each Innovex Subsidiary has been duly organized and
is validly existing under the Laws of the jurisdiction of its organization.
Each Innovex Subsidiary has the corporate power and authority to own, lease and
operate its property and conduct its business as now being conducted.  Each
Innovex Subsidiary is duly qualified to do business in each jurisdiction in
which the character or location of the properties owned or leased by such
Innovex Subsidiary or the nature of the business conducted by such Innovex
Subsidiary makes such qualification necessary under applicable Laws, except for
such failures to be so qualified or licensed that would not have individually
or in the aggregate a Material Adverse Effect on Innovex and its Subsidiaries
taken as a whole.  All issued and outstanding share capital of the Innovex
Subsidiaries has been duly authorized and validly issued and is fully paid and
non-assessable, and none was issued in violation of any Stock Acquisition Right
for securities of any Innovex Subsidiary.  There are no outstanding Stock
Acquisition Rights for any securities of any Innovex Subsidiary.  Except as set
forth on





                                       6
<PAGE>   12

Schedule 2.5, no share capital of any Innovex Subsidiary is held by any Person
other than Innovex or is subject to any Encumbrance.

         2.6.    Financial Statements; No Material Changes; Budget and
                 Projections.

                 (a)      Innovex Financial Statements.

                          (i)  Innovex has furnished Quintiles with the
         combined balance sheets of Innovex and its Subsidiaries as of March
         31, 1996 (the "Innovex Balance Sheet", March 31, 1996 being referred
         to herein as the "Innovex Balance Sheet Date") and March 31, 1995, and
         the related combined income statements, statements of cash flows, and
         statements of changes in shareholders' equity for the years then
         ended, all audited by KPMG (collectively, the "Innovex Audited
         Financial Statements") and designated as delivered pursuant to this
         Section.   Innovex also has furnished Quintiles with the unaudited
         combined balance sheets of Innovex and its Subsidiaries as of June 30,
         1996  and the related unaudited combined income statements, statements
         of cash flows, and statements of changes in shareholders' equity for
         the three months then ended (collectively, the "Innovex Interim
         Financial Statements", all designated as delivered pursuant to this
         Section).  Further, Innovex will provide to Quintiles, within 25 days
         after the end of each calendar month prior to the Closing Date (but in
         no event later than two (2) business days prior to the Closing Date,
         if the Closing Date falls on the 25th or any later day of a month),
         unaudited management accounts for Innovex and its Subsidiaries for
         such calendar month (collectively, the "Innovex Management Accounts,"
         and together with the Innovex Audited Financial Statements and the
         Interim Innovex Financial Statements, the "Innovex Financial
         Statements").   All of the Innovex Financial Statements, including the
         notes thereto, have been and will be prepared in accordance with all
         applicable accounting standards and legal requirements in the United
         Kingdom, including without limitation United Kingdom Generally
         Accepted Accounting Principles, consistently followed throughout the
         periods indicated, except that the Innovex Interim Financial
         Statements and the Innovex Management Accounts are or will be subject
         to normal, recurring adjustments (which will not be material
         individually or in the aggregate), lack footnotes and other
         presentation items and are presented in a summary format.  The Innovex
         Balance Sheet, all such other balance sheets, and all comparable
         information included in the Innovex Management Accounts fairly
         present, or will fairly present, the financial condition of Innovex
         and its Subsidiaries on a combined basis at the respective dates
         thereof; and the related income statements, statements of cash flows
         and statements of changes in shareholders' equity (if applicable), and
         comparable information included in the Innovex Management Accounts
         fairly present, or will fairly present, the results of the operations
         of Innovex and its Subsidiaries on a combined basis and the changes in
         their financial position for the periods indicated.  Except as set
         forth on Schedule 2.6 attached hereto,





                                       7
<PAGE>   13

         there are no material intercompany transactions between or among
         Innovex and any Innovex Subsidiaries and no transactions between
         Innovex or any Innovex Subsidiary and any Affiliate thereof not
         reflected in the Innovex Financial Statements.

                 (ii)     Innovex also has furnished Quintiles with the
         combined balance sheets of the "Innovex Companies" (as defined
         therein) as at March 31, 1996 and March 31, 1995, and the related
         combined income statements, statements of cash flows, statements of
         total recognized gains and losses, and statements of changes in
         shareholders' equity for the years then ended and the year ended March
         31, 1994, (collectively, the "Innovex Annual F-1 Financial
         Statements") and designated as delivered pursuant to this Section.
         Innovex also has furnished Quintiles with the unaudited condensed
         consolidated balance sheets of the Innovex Companies as of June 30,
         1996 and the related unaudited condensed consolidated income
         statements, statements of cash flows, and statements of total
         recognized gains and losses for the three months ended June 30, 1995
         and June 30, 1996 and designated as delivered pursuant to this Section
         (the "Innovex Interim F-1 Financial Statements," and together with the
         Innovex Annual F-1 Financial Statements, the "Innovex F-1 Financial
         Statements").  All of the Innovex F-1 Financial Statements, including
         the notes thereto (except as otherwise expressly stated therein as to
         preparation in accordance with United States Generally Accepted
         Accounting Principles), have been prepared in accordance with United
         Kingdom General Accepted Accounting Principles, consistently followed
         throughout the periods indicated, and the portions thereof which
         purport to reflect application of United States Generally Accepted
         Accounting Principles have been prepared in accordance therewith,
         consistently followed throughout the periods indicated, except that
         the Innovex Interim F-1 Financial Statements are subject to normal,
         recurring adjustments (which will not be material individually or in
         the aggregate), lack footnotes and other presentation items and are
         presented in a summary format and except as set forth in Schedule 2.6.

                 (b)      Since March 31, 1996, there has been no event, fact,
condition, circumstance or other development which has had or could be
reasonably expected to have individually or in the aggregate a Material Adverse
Effect on Innovex and its Subsidiaries, taken as a whole, whether as a result
of any legislative or regulatory change, revocation of any license or right to
do business, Casualty, termination or impairment of any material Contract or
business relationship or otherwise; provided, however, Innovex's April 1996
reorganization described in the Innovex F-1 referred to below shall be excluded
from this Section 2.6(b).

                 (c)      Innovex has furnished Quintiles with true and
complete copies of  Innovex's financial budget for its fiscal year ending March
31, 1997 and financial projections for the year ended December 31, 1997,
together with a description of the assumptions reflected in such budget and
projections, all designated as delivered pursuant  to this Section.   Such
financial





                                       8
<PAGE>   14

budget and financial projections have been prepared on the basis of accounting
policies that are consistent with the Innovex Audited Financial Statements, and
such financial budget and financial projections (and the underlying
assumptions), taken as a whole, are reasonable.

                 (d)      Innovex's backlog (calculated based on fee payments
anticipated to be received under letters of intent and legally binding written
agreements for the provision of contract research and sales and marketing
services to third parties) ("Backlog") as of September 30, 1996 was at least
L.140,000,000, of which at least L.70,000,000 is attributable to the
twelve-month period ended December 31, 1997.  Innovex has delivered to
Quintiles a true and correct report describing such Backlog, certified as such
by Innovex's principal financial officer and designated as delivered pursuant
to this Section.

         2.7.    Books and Records.

                 (a)      The Memorandum and Articles of Association or
equivalent Organizational Documents of Innovex and the Innovex Subsidiaries,
and the statutory and other corporate books and records, as previously made
available to Quintiles and its representatives, contain accurate records of all
meetings of and properly record all material corporate action taken by the
shareholders and Boards of Directors (including committees thereof) of Innovex
and each Innovex Subsidiary and show all share capital transactions concerning
Innovex or such Subsidiary, as the case may be.

                 (b)      The register of members and other statutory books or
equivalent corporate records of Innovex and each Innovex Subsidiary have been
properly kept and contain an accurate and complete record of the matters
required to be recorded thereon.   Except as set forth in Schedule 2.7 attached
hereto, since September 1, 1996, no alteration has been made to the Memorandum
and Articles of Association or equivalent Organizational Documents of Innovex
or any Innovex Subsidiary, and no resolution of any kind of the shareholders of
Innovex or any Innovex Subsidiary has been passed (other than resolutions
related to routine business).

                 (c)      Except as set forth in Schedule 2.7 attached hereto,
all returns, particulars, resolutions and documents required by the Companies
Acts or any other applicable Law to be filed with the Registrar of Companies,
or any other authority, in respect of Innovex and each Innovex Subsidiary have
been duly filed and were complete and correct; and due compliance has been made
with all the provisions of such Laws in connection with the formation of
Innovex and each Innovex Subsidiary, the allotment or issue of shares,
debentures and other securities, the payment of dividends and the conduct of
its business.  All charges in favor of Innovex and each Innovex Subsidiary have

each case, the lessee is not in default thereunder, and no written waiver,

granted by the lessor; and there exists no event of default or event,
occurrence, condition or act (including the transactions contemplated by this
Agreement) which, with the giving of notice, the lapse of time or the happening
of any further event or condition, would become a default under such lease,
except in each case as would not individually or in the aggregate have a
Material Adverse Effect on Innovex and its Subsidiaries taken as a whole.





                                       10

repair and is adequate and suitable for the purposes for which it is presently

         2.12.   Contracts.  Except as set forth in Schedule 2.12 attached
hereto, neither Innovex nor any Innovex Subsidiary is a party to or is bound by

any Person, (i) any agency Contract or Contract for the distribution or

Innovex Subsidiary agrees to hold harmless or indemnify such Person against or
contribute to such Person in respect of any liability, cost or expense of or
relating to Innovex or such Innovex Subsidiary or relating to the transactions
contemplated by this Agreement or any other Transaction Document.  Each
Contract set forth in Schedule 2.12 (or required to be set forth in Schedule
2.12) is in full force and effect, and there exists no, and neither any
Shareholder, Innovex nor any Innovex Subsidiary has received any notice or
other communication asserting the





                                       11
<PAGE>   17

actual or alleged existence of any, default or event of default or event,
occurrence, condition or act (including the consummation of the transactions
contemplated by this Agreement) which, with the giving of notice, the lapse of
time or the happening of any other event or condition, would become a material
default or material event of default thereunder.  Neither any Shareholder,
Innovex nor any Innovex Subsidiary has violated any of the terms or conditions
of any material Contract set forth in Schedule 2.12 (or required to be set
forth in Schedule 2.12, or which would at any time within the past two years
have been required to be set forth in a schedule listing the types of Contracts
required to be set forth in Schedule 2.12) in any material respect.  To the
knowledge of Innovex, neither Innovex nor any Innovex Subsidiary has
experienced, nor do they anticipate any dispute with any supplier, vendor,
contractor, customer or client with which Innovex or such Innovex Subsidiary
has conducted business during the one year period ending on the date of this
Agreement, nor has any such party notified Innovex or any Innovex Subsidiary of
any desire or intention to reduce the volume under, terminate or otherwise
alter materially any material Contract with Innovex or any Innovex Subsidiary,
in each case except as set forth in Schedule 2.12 or as would not individually
or in the aggregate have a Material Adverse Effect on Innovex and its
Subsidiaries taken as a whole.

         2.13.   No Conflicts.  The execution and delivery of this Agreement
and each other applicable Transaction Document by Innovex and the Shareholders
do not, and the performance of this Agreement and each other applicable
Transaction Document by Innovex and the Shareholders will not, (i) conflict
with or violate any provision of the Organizational Documents of Innovex or any
Innovex Subsidiary, (ii) assuming that all consents, approvals, authorizations
and other actions described in Schedule 2.13 attached hereto have been obtained
and all filings and obligations described in Schedule 2.13 attached hereto have
been made, conflict with or violate any Law applicable to Innovex or any
Innovex Subsidiary or by which any property or asset of Innovex or any Innovex
Subsidiary is bound or affected, or (iii), except as set forth in Schedule
2.13, result in any breach of or constitute a default (or an event which with
notice or lapse of time or both would become a default) under, or give to
others any right of termination, amendment, acceleration or cancellation of, or
result in the creation of a lien or other encumbrance on any property or asset
of Innovex or any Innovex Subsidiary pursuant to, any Contract except, with
respect to clauses (ii) and (iii), for any such conflicts, violations,
breaches, defaults, or other occurrences which would not, individually or in
the aggregate, have a Material Adverse Effect on Innovex and its Subsidiaries
taken as a whole.

         2.14.   Litigation.  Except as set forth in Schedule 2.14 attached
hereto, there is no action, suit, proceeding at law or in equity, arbitration
or administrative or other proceeding or investigation by or before any
governmental or other instrumentality or agency pending or, to Innovex's
knowledge,  threatened against or affecting Innovex or any Innovex Subsidiary
or  any of their respective properties or rights which is reasonably likely to
have a Material Adverse Effect on Innovex and its Subsidiaries taken as a
whole; and neither Innovex nor any Shareholder knows





                                       12
<PAGE>   18

of any basis for any such action, proceeding or investigation.  Neither Innovex
nor any Innovex Subsidiary is subject to any judgment, order or decree entered
in any lawsuit or proceeding which may have a Material Adverse Effect on
Innovex and its Subsidiaries taken as a whole or impair materially the ability
of Innovex or any Innovex Subsidiary to acquire any property or conduct
business in any area in which it currently conducts or anticipates conducting
business.

         2.15.   Taxes.   Except as set forth on Schedule 2.15 or as otherwise
would not have a Material Adverse Effect on Innovex and its Subsidiaries taken
as a whole:

                 (a)      Innovex and each Innovex Subsidiary has filed or
caused to be filed, within the times and manners prescribed by Law, all
domestic and foreign tax returns, tax reports and tax computations which are
required by applicable Law to be filed by, or with respect to, Innovex or such
Innovex Subsidiary (collectively, "Tax Returns").  True copies of all such Tax
Returns, which have been requested have been made available to Quintiles.  Such
Tax Returns reflect accurately all liability (either specifically or by way of
general provisions) for Taxes (as defined below) of Innovex and its
Subsidiaries for the periods covered thereby that are required to be reflected
thereon.  All domestic and foreign income, profits, gain, value added,
franchise, sales, use, occupancy, excise and other taxes, duties and
assessments (including interest and penalties) (collectively, "Taxes") which
are or may become payable by or due from Innovex or any Innovex Subsidiary have
been fully paid or adequately disclosed and fully provided for in the books and
financial statements of Innovex or such Innovex Subsidiary, as applicable
(except in the case of deferred taxes).  The United Kingdom corporation tax
liability of Innovex has been finally determined for all fiscal years to and
including the fiscal year ended March 31, 1993, or the period for assessment of
the Taxes in respect of such periods has expired.  No examination or audit of
any tax return of Innovex or any Innovex Subsidiary is currently in progress,
and no basis for any assessment is known to exist.  There are no outstanding
agreements or waivers extending the statutory period of limitation applicable
to any tax return of Innovex or any Innovex Subsidiary.  For purposes of this
Section 2.15, "Taxation" shall mean all forms of taxation, duties, imposts and
levies whatsoever and whenever imposed and whether of the United Kingdom or
elsewhere, including without limitation:  (i) income tax, corporation tax,
capital gains tax, inheritance tax, transfer tax, stamp duty, stamp duty
reserve tax, value added tax, customs and other import duties and national
insurance contributions, general rates, water rates or other local rates or
property taxes, and any payment whatsoever which Innovex or any Innovex
Subsidiary may be or become bound to make to any Person as a result of any
enactment relating to Taxation and any other taxes, duties or levies
supplementing or replacing any of the above; and (ii) all costs, charges,
interest, fines, penalties, and expenses incidental, or relating, to any
Taxation.

                 (b)      All returns, computations, and payments which are
required to have been made by Innovex and each Innovex Subsidiary for any
Taxation purpose have been made within the requisite periods and are up to
date, correct and on a proper basis, and none of them is the





                                       13
<PAGE>   19

subject of any dispute with the Inland Revenue or other Taxation authorities.
All particulars furnished to the Inland Revenue or other Taxation authorities
in connection with the application for any consent or clearance on behalf of,
or otherwise affecting Innovex or any Innovex Subsidiary, fully and accurately
disclosed all facts and circumstances material for the decision of those
authorities; any consent or clearance is valid and effective; and any
transaction for which the consent or clearance has previously been obtained has
been carried into effect (if at all) only in accordance with the terms of the
relative application and consent or clearance.  Neither Innovex nor any Innovex
Subsidiary has taken any action which has had, or will have, the result of
altering, prejudicing or in any way disturbing any arrangement or agreement
which it has previously negotiated with any Taxation or customs authority.
Innovex has not, since the Innovex Balance Sheet Date, paid or become liable to
pay any penalty or interest charged by virtue of any Taxation Law.  Innovex and
each Innovex Subsidiary has properly operated the PAYE system, and any
equivalent system in any other jurisdiction, by deducting tax, as required by
Law, from all payments made or treated as made to its employees, or former
employees or others, and has accounted to the Inland Revenue or other Taxation
authority for all tax deducted by it and for all tax chargeable on benefits
provided for its employees or former employees or others.

                 (c)      Except as set forth on Schedule 2.15, all expenditure
which Innovex has incurred on the provision of machinery or plant has qualified
(if not deductible as a trading expense of trade carried on by Innovex) for
writing down allowances under Capital Allowance Act 1990 ("CAA") Section 24
(writing down allowances and balancing adjustments) or is dealt with under
Section 137 CAA as scientific research allowances.

         2.16.   Liabilities; Indebtedness.

                 (a)      There are no liabilities, obligations or indebtedness
of or claims against Innovex or any Innovex Subsidiary, whether known or
unknown, due or not yet due, asserted or unasserted (whether or not contingent
or probable of assertion), arising from, or in connection with, or based upon
acts, omissions, or occurrences existing, occurring or taking place on or
before the Closing Date, whether or not discovered, known, asserted, expected
or contemplated by any party or third party, and Quintiles shall not suffer or
be subject to any Losses (as defined in Section 8.2(a) below) arising from the
foregoing, whether such Losses occur before or after the Closing Date, except:
(i) those liabilities as set forth in the Innovex Balance Sheet or referred to
in the notes thereto, and (ii) other liabilities which, individually or in the
aggregate, would not have a Material Adverse Effect on Innovex and its
Subsidiaries taken as a whole.

                 (b)      Schedule 2.16 is an accurate and complete listing of
all material Indebtedness of Innovex and each Innovex Subsidiary (excluding
intercompany Indebtedness). Innovex and each Innovex Subsidiary has performed
and is in compliance in all material respects with all applicable terms of all
such Indebtedness and all instruments and agreements relating





                                       14
<PAGE>   20

thereto, and no default or event of default, or event or condition which with
the giving of notice, the lapse of time, the satisfaction of any other
condition or any combination of the foregoing, would constitute such a default
or event of default, exists with respect to any such Indebtedness.  The sum of
the indebtedness for borrowed money (excluding for the avoidance of doubt
capital lease obligations) of Innovex and the Innovex Subsidiaries, on a
combined basis, does not exceed L.25,000,000.  Set forth on Schedule 2.16 are
the amounts necessary on the date of this Agreement to make all of the payments
in respect of each of the loan stock and credit facilities, and the purchase of
the Preference Shares, all referred to in Section 1.1.

         2.17.   Insurance.       Innovex carries insurance policies with
independent third party insurers which, with respect to their amounts and types
of coverage, are adequate to insure against risks to which Innovex and the
Innovex Subsidiaries and their respective property and assets are normally
exposed in the operation of their respective businesses, including without
limitation professional liability.  All such policies which are material to the
business of Innovex and its Subsidiaries are in full force and effect and,
except as set forth in Schedule 2.17, are free from any right of termination on
the part of the applicable insurance carriers.  There are no outstanding unpaid
premiums except in the ordinary course of business, and neither Innovex nor any
Innovex Subsidiary has received any notice of cancellation or non-renewal of
any such policy.  Except as set forth in Schedule 2.17, neither Innovex nor any
Innovex Subsidiary is aware of any risks, situations, occurrences or other
matters which have been disclosed, or should have been disclosed, to insurance
carriers or brokers in connection with any application for insurance as a
result of which an insurance carrier would have a right to cancel the
corresponding insurance policy or deny coverage with respect to any such right.
There exists no event of default or event, occurrence, condition or act
(including the transactions contemplated by this Agreement) which, with the
giving of notice, the lapse of time or the happening of any further event or
condition, would become a default or occasion a material premium increase under
any such policy or give rise to, and Innovex has no anticipation of, any
termination or cancellation thereof or material premium increase therefor.

         2.18.   Intellectual Property.  The lawful operation of the businesses
of Innovex and the Innovex Subsidiaries as currently conducted and as currently
planned to be conducted requires no material rights under Intellectual Property
(as hereinafter defined) other than rights under Intellectual Property listed
in Schedule 2.18 attached hereto and rights granted to Innovex or any Innovex
Subsidiary pursuant to agreements listed in Schedule 2.18.  Except as otherwise
set forth in Schedule 2.18, Innovex or its Subsidiaries own all right, title
and interest in the Intellectual Property listed in Schedule 2.18, including
without limitation exclusive rights to use and license the same.  Each item of
Intellectual Property listed in Schedule 2.18 has been duly registered with,
filed in, or issued by a domestic or foreign governmental agency to the extent
specified in Schedule 2.18, and each such registration, filing and issuance
remains in full force and effect.  No claim adverse to the interests of Innovex
or any Innovex Subsidiary in the Intellectual Property or





                                       15
<PAGE>   21

agreements listed in Schedule 2.18 has been made in litigation.  To Innovex's
knowledge,  no such claim has been threatened or asserted, and Innovex knows of
no basis or alleged basis for any such claim, and, to the knowledge of Innovex,
no Person has infringed or otherwise violated Innovex's or any Innovex
Subsidiary's right in any of the Intellectual Property or agreements listed in
Schedule 2.18.  To the knowledge of Innovex, neither the Intellectual Property
listed in Schedule 2.18 nor Innovex's or any Innovex Subsidiary's use thereof
infringes or has infringed at any time upon the valid Intellectual Property
rights of another, and no litigation is pending wherein Innovex or any Innovex
Subsidiary is accused of infringing or otherwise violating the Intellectual
Property right of another, or of breaching a contract conveying rights under
Intellectual Property.  To Innovex's knowledge, no such claim has been asserted
or threatened against Innovex or any Innovex Subsidiary.  For purposes of this
Section 2.18, "Intellectual Property" means domestic and foreign patents,
patent applications, registered and unregistered trademarks and service marks,
trademark and service mark applications, trade names and trade dress,
registered and unregistered copyrights, computer programs and databases, trade
secrets, know how and proprietary information.

         2.19.   Licenses.

                 (a)      Schedule 2.19 attached hereto contains an accurate
and complete list of all licenses, franchises, permits, rights and other
approvals and authorizations (collectively, "Licenses") held by Innovex or any
Innovex Subsidiary that are material to the operation of the business of
Innovex and its Subsidiaries taken as a whole.  Except as set forth in Schedule
2.19, Innovex and its Subsidiaries own or otherwise lawfully use each License
necessary or required by applicable Law to conduct their respective businesses
as presently conducted, free and clear of all Encumbrances, and all such
Licenses are in full force and effect, not subject to any current default or
right of cancellation, termination or revocation except in each case as would
not individually or in the aggregate have a Material Adverse Effect on Innovex
or any Innovex Subsidiary.

                 (b)      Each of  Innovex's or any Innovex Subsidiary's
employees who is practicing as a physician, nurse or pharmacist is identified
on Schedule 2.19, and each such employee is duly Licensed and in good standing
to practice as a physician, nurse or pharmacist, as the case may be, in each
jurisdiction in which such employee renders services for or on behalf of
Innovex or any Innovex Subsidiary, except as set forth on Schedule 2.19 or as
would not otherwise result in a Material Adverse Effect on Innovex and its
Subsidiaries taken as a whole.  To Innovex's knowledge, none of the employees
listed on Schedule 2.19 is or has been subject to any claim in connection with
his or her practice as a physician, nurse or pharmacist, as the case may be,
and no fact or occurrence is known to exist which is likely to give rise to the
revocation of any such License.





                                       16
<PAGE>   22
         2.20.   Compliance with Laws, etc.  Innovex and each Innovex
Subsidiary is and at all times has been in compliance with all applicable Laws
in all material respects.  Except as set forth in Schedule 2.20, there exists
no event, occurrence, condition or act which, with the giving of notice, the
lapse of time or the happening of any further event or condition would
constitute a material violation of any applicable Law by Innovex or any Innovex
Subsidiary.  None of Innovex, any Innovex Subsidiary, or any of their
respective Affiliates, nor any Person acting for or on behalf of any thereof
has at any time made or participated in any bribe, kickback or illegal payment.
All studies and services performed by Innovex and each of its Subsidiaries
comply in all material respects with all applicable Good Clinical Practices and
comparable guidelines in other countries where Innovex and the Innovex
Subsidiaries carry on business.

         2.21.   Employee Relations.  There is no labor strike, dispute,
slowdown or stoppage actually pending or threatened against or involving
Innovex or any Innovex Subsidiary.  Except as set forth in Schedule 2.21,
neither Innovex nor any Innovex Subsidiary has entered into any recognition
agreement or other agreement or arrangement with any trade union or other body
representing employees.  No recognition agreement is currently being negotiated
by Innovex or any Innovex Subsidiary, nor is Innovex or any Innovex Subsidiary
aware of any current efforts to organize any trade union or other body
representing Innovex's or any Innovex Subsidiary's employees.  Neither Innovex
nor any Innovex Subsidiary is currently, or during the last three years has
been, involved in any material industrial dispute.

         2.22.   Pension Schemes and Benefit Plans.

                 (a)  Non U.S. Except with respect to the schemes described in
Schedule 2.22 attached hereto (the "Schemes"), neither Innovex nor any Innovex
Subsidiary has any obligation to pay any pension or make any other payment
after retirement, death or disability (whether of a temporary or permanent
nature) or otherwise to provide other material benefits of any variety
whatsoever to, or in respect of, any person who is now or has been an officer
or employee of Innovex or any Innovex Subsidiary or a spouse or dependent of
such officer or employee, and no change in the benefits currently being
provided under any Scheme has been announced by Innovex or any Innovex
Subsidiary or is being considered.  Innovex has provided Quintiles true and
complete copies of all documents governing or relating to each Scheme which
have been requested.  Innovex and each of its Subsidiaries, as the case may be,
has adopted, administered and conducted each Scheme in accordance with all
applicable Laws in all material respects.

                 (b)  Non U.S. Benefits, Discretions and Funding

                          With respect to each Scheme, except as set forth on

                                  ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF QUINTILES

         Quintiles represents and warrants to the Shareholders and agrees as
follows:

         3.1.    Existence of Quintiles.  Quintiles is a corporation duly
organized and validly existing under the Laws of the State of North Carolina.
Quintiles has the corporate power and authority to own, lease and operate its
property and conduct its business as now being conducted.  Quintiles is duly
qualified to do business in each jurisdiction in which the character or
location of the properties owned or leased by Quintiles or the nature of the
business conducted by Quintiles makes such qualification necessary under
applicable Laws, except for such failures to be so qualified or licensed that
would not have, individually or in the aggregate, a Material Adverse Effect on
Quintiles and its Subsidiaries taken as a whole.

         3.2.    Capitalization.  The authorized capital stock of Quintiles
consists of 50,000,000 shares of common stock, par value $0.01 per share
("Common Stock"), and 25,000,000 shares of preferred stock, par value $0.01 per
share ("Preferred Stock").  At the close of business on September 30, 1996,
21,828,299 shares of Common Stock and no shares of Preferred Stock were issued
and outstanding.  All such outstanding capital stock has been, and the
Quintiles Shares will be, when issued as provided in this Agreement, duly
authorized and validly issued and fully paid and nonassessable, and none was
(or in the case of the Quintiles Shares will be) issued in violation of any
Stock Acquisition Right for securities of Quintiles.  Except as set forth on
Schedule 3.2, there are no outstanding Stock Acquisition Rights for securities
of Quintiles as of the date of this Agreement, other than as contemplated by
this Agreement.  As of the Closing and after giving effect to the issuance of
the Quintiles Shares, and except as set forth in Schedule 3.2, Quintiles shall
have issued and outstanding capital stock consisting of not in excess of
33,000,000 shares of Common Stock (subject to additional issuances in respect
of the matters listed in Schedule 3.2) and no shares of Preferred Stock; no
other capital stock shall be issued or outstanding; and no Stock Acquisition
Rights for securities of Quintiles shall be outstanding.

         3.3.    Power and Authority of Quintiles.  Quintiles has all requisite
power and authority to enter into and deliver this Agreement and the other
Transaction Documents to which it is a party, to perform its obligations
hereunder and thereunder and to consummate the transactions





                                       22
<PAGE>   28

contemplated hereby and thereby.  Quintiles' execution, delivery and
performance of this Agreement and the other Transaction Documents and
Quintiles' consummation of the transactions contemplated hereby and thereby
have been duly and validly authorized by all corporate, director, shareholder
and other action required of Quintiles by applicable Law and Quintiles'
Organizational Documents (other than the approval of the issuance of the
Quintiles Shares by the holders of not less than a majority of Quintiles'
Common Stock voted in accordance with Nasdaq Stock Market rules).  This
Agreement and the other Transaction Documents to which Quintiles is a party
constitute the valid and legally binding obligations of Quintiles, enforceable
against Quintiles in accordance with their respective terms.

         3.4.    SEC Documents.  Quintiles has filed all required reports,
schedules, forms, statements and other documents with the SEC since January 1,
1993 (the "Quintiles SEC Documents").  As of their respective dates, each of
the Quintiles SEC Documents complied in all material respects with the
requirements of the Securities Act or the Exchange Act, as the case may be, and
the rules and regulations of the SEC promulgated thereunder applicable to such
Quintiles SEC Document, and none of the Quintiles SEC Documents contained any
untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.  Except to the extent that information contained in any Quintiles
SEC Document has been revised or superseded by a later filed Quintiles SEC
Document, none of the Quintiles SEC Documents contains any untrue statement of
a material fact or omits to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.

         3.5.    Financial Statements; No Material Changes.

balance sheets of Quintiles and its Subsidiaries as of December 31, 1995 (the

the years then ended, all audited by Ernst & Young LLP (collectively, the

                 (b)      Since June 30, 1996, there has been no event, fact,
condition, circumstance or other development which has had or could be
reasonably expected to have a Material Adverse Effect on Quintiles and its
Subsidiaries, taken as a whole, whether as a result of any legislative or
regulatory change, revocation of any license or right to do business, Casualty,
termination or impairment of any material Contract or business relationship or
otherwise.

                 (c)      Except as set forth in Quintiles SEC Documents filed
and publicly available prior to the date of this Agreement, neither Quintiles

(whether accrued, absolute, contingent or otherwise) which, individually or in
the aggregate, would have a Material Adverse Effect on Quintiles and its
Subsidiaries taken as a whole.

taken as a whole, Quintiles or a Quintiles Subsidiary (as the case may be) has
good and marketable title to each parcel of Quintiles Owned Real Property, free
and clear of any Encumbrances.

         3.9.    No Conflicts.  The execution and delivery of this Agreement

or other encumbrance on any property or asset of Quintiles or any Quintiles
Subsidiary pursuant to, any Contract, except, with respect to clauses (ii) and
(iii), for any such conflicts, violations, breaches, defaults, or other
occurrences which would not, individually or in the aggregate, have a Material
Adverse Effect on Quintiles and its Subsidiaries taken as a whole.

                   CERTAIN PRE-CLOSING AND RELATED COVENANTS

         4.1.    Conduct of Business of Innovex and Innovex Subsidiaries.
During the period from the date of this Agreement to the Closing (or the
earlier termination of this Agreement pursuant to Section 9.16 below), Innovex
shall, and shall cause each Innovex Subsidiary to conduct its operations only
according to its ordinary and usual course of business and to the extent
consistent therewith, use all reasonable efforts to preserve intact its
corporate organization, keep available the services of its officers and key
employees, maintain its existing relationships with suppliers, vendors,
contractors, customers and others having business relationships with Innovex or
any Innovex Subsidiary, and perform in all material respects all of Innovex's
and the Innovex Subsidiaries' obligations under all Contracts to which Innovex
or any Innovex Subsidiary is a party or by which it or any of its assets or
properties are bound, except in each case to the extent that failure to do so
would not have a Material Adverse Effect on Innovex and its Subsidiaries, taken





                                       29
<PAGE>   35

as a whole.  Notwithstanding the immediately preceding sentence, prior to the
Closing (or the earlier termination of this Agreement pursuant to Section 9.16
below), except as may be first approved in writing by Quintiles or as is
otherwise permitted or required by this Agreement, the Management Shareholders,
Innovex and each Innovex Subsidiary shall cause (a) Innovex's and each Innovex
Subsidiary's Organizational Documents to be maintained in their forms on the
date of this Agreement, (b) the compensation payable or to become payable by
Innovex and each Innovex Subsidiary to each officer, employee or agent of
Innovex or such Innovex Subsidiary to be maintained at their levels on the date
of this Agreement except to the extent required by Law or by any existing plan
or agreement and other than general increases in the compensation of employees
in the ordinary course of business consistent with past practices, (c) Innovex
and each Innovex Subsidiary to refrain from making any bonus, pension,
retirement or insurance payment or arrangement to or with any such persons
except those that may have already been accrued or may be required by law or by
any existing plan or agreement, other than payments or arrangements made in the
ordinary course of business consistent with past practices, (d) Innovex and
each Innovex Subsidiary to refrain from entering into any Contract except
Contracts in the ordinary course of business having a value of less than
L.500,000 (including any Contract for the provision of services to customers)
and Contracts for capital expenditures in an individual or aggregate amount not
to exceed L.500,000 and consult with Quintiles before entering into a Contract
involving expenditure by Innovex of more than L.500,000, (e) Innovex and each
Innovex Subsidiary to refrain from issuing or selling, or issuing any rights to
purchase or subscribe for, or subdividing or otherwise changing in any respect
shares of Innovex's or any Innovex Subsidiary's share capital or any Share
Acquisition Rights and (f) Innovex and each Innovex Subsidiary to refrain from
taking any of the actions referred to in Section 2.25 hereof.  The Shareholders
and Innovex agree not to take or omit to take any action which would cause the
representations and warranties contained in Article II hereof to be or become
untrue or incorrect.  During the period from the date of this Agreement to the
Closing Date, the Management Shareholders shall confer, and shall cause Innovex
and the Innovex Subsidiaries to confer, on a regular and frequent basis, with
one or more designated representatives of Quintiles to report operational
matters and to report the general status of ongoing operations.

         4.2.    Exclusive Dealing.  During the period from the date of this
Agreement to the Closing (or the earlier termination of this Agreement pursuant
to Section 9.16 below) and except as otherwise authorized by Quintiles in
writing, the Shareholders shall, and the Management Shareholders shall cause
Innovex and the Innovex Subsidiaries to, and Innovex and the Innovex
Subsidiaries shall, refrain from taking any action directly or indirectly to
(a) encourage, initiate or engage in discussions or negotiations with, or
provide any information to, any Person other than Quintiles concerning any
proposal for the sale or purchase of any portion of the share capital
(including in a public offering) or twenty percent (20%) or more of the assets
of, or merger or other business combination, or similar transaction involving
Innovex or any Innovex Subsidiary and refrain from otherwise pursuing or
endorsing any such transaction, or (b) undertake or cause to





                                       30
<PAGE>   36

occur any offering or sale of Innovex's or any of Innovex's Affiliates'
securities to the public (any such offering or sale being referred to herein as
a "Public Offering"); provided that this Section 4.2 shall not restrict Innovex
from consulting with its legal and financial advisors and its independent
accountants regarding the feasibility of a Public Offering in the event that
this Agreement is terminated.  The Shareholders and Innovex shall notify
Quintiles promptly if any proposals concerning any merger, consolidation, sale
of assets, tender offer, sale of shares or similar transaction involving
Innovex, any Innovex Subsidiary or any significant assets of Innovex or any
Innovex Subsidiary (any such proposal being referred to herein as an
"Acquisition Proposal"), or if any request for confidential information
regarding Innovex or any Innovex Subsidiary is received, and shall provide to
Quintiles such information regarding any such Acquisition Proposal or request
as Quintiles shall reasonably request.

         4.3.    Access to Information.  Except as required pursuant to any
confidentiality agreement or similar agreement or arrangement to which Innovex
or Quintiles or any of their respective Subsidiaries is a party or pursuant to
applicable law or the regulations or requirements of any stock exchange or
other regulatory organization with whose rules Innovex or Quintiles are
required to comply, from the date of this Agreement to the Closing, Innovex and
Quintiles shall (and shall cause their respective Subsidiaries to):  (i)
provide to the other (and its officers, directors, employees, accountants,
consultants, legal counsel, agents and other representatives, collectively,
"Representatives") access at reasonable times upon prior notice to the
officers, employees, agents, properties, offices and other facilities of the
other and its Subsidiaries and to the books and records thereof and (ii)
furnish promptly such information concerning the business, properties,
contracts, assets, liabilities, personnel and other aspects of the other party
and its Subsidiaries as the other party or its Representatives may reasonably
request.  No investigation conducted pursuant to this Section 4.3 shall affect
or be deemed to modify any representation or warranty made in this Agreement.
Subject to compliance with applicable law, from the date hereof until the
Closing, each of Innovex and Quintiles shall confer on a regular and frequent
basis with one or more representatives of the other to report on the general
status of ongoing operations and shall, upon reasonable notice, provide the
other with such financial and operating data and other information with respect
to its business and properties as the other party shall from time to time
reasonably request.  In the event of termination of this Agreement without
consummation of the transactions contemplated hereby, each party shall keep
confidential any material information obtained from the others concerning their
respective properties, operations and business (unless readily ascertainable
from public or published information or trade sources) until the same ceases to
be material (or becomes so ascertainable) and, upon request, shall return all
copies of any schedules, statements, documents or other written information
obtained in connection therewith.

         4.4.    Conduct of Business of Quintiles and Quintiles Subsidiaries.
During the period from the date of this Agreement to the Closing Date,
Quintiles shall conduct its operations only according to its ordinary and usual
course of business.  Notwithstanding the immediately preceding





                                       31
<PAGE>   37

sentence, prior to the Closing (or the earlier termination of this Agreement
pursuant to Section 9.16 below), (a) except as may be first approved in writing
by Innovex or as is otherwise permitted or required by this Agreement, and
except in connection with the acquisition by Quintiles of BRI International
Inc. and related transactions, Quintiles shall not (i) merge, consolidate with
or consummate any other business combination with any person other than as
permitted by the following clause (ii), (ii) acquire or agree to acquire by
merging or consolidating with, or by purchasing a substantial equity interest
in or a substantial portion of the assets of, or by any other manner, any
business or any corporation, partnership, association or other business entity,
in a transaction or series of related transactions for a purchase price in
excess of $100 million in the aggregate, or (iii) issue or sell, or issue any
rights to purchase or subscribe for, or subdivide or otherwise change in any
respect shares of Quintiles' share capital, except to the extent required by
law or by any existing plan or agreement, other than general increases in the
compensation of employees in the ordinary course of business consistent with
past practices and except for the issuance to directors, officers or employees
of Quintiles of options to purchase shares of Common Stock of Quintiles in a
manner and quantity consistent with past practices, and (b) unless Quintiles
has consulted beforehand with Innovex (except as is otherwise permitted or
required by this Agreement), Quintiles shall cause (i) the Quintiles
Organizational Documents to be maintained in their forms on the date of this
Agreement and (ii) Quintiles and each Quintiles Subsidiary to refrain from
entering into any Contracts for capital expenditures in an individual or
aggregate amount not to exceed L.1,000,000.  Quintiles agrees not to take or
omit to take any action which would cause the representations and warranties
contained in Article III hereof to be or become untrue or incorrect.

         4.5.    Proxy Statement.

                  (a)  As soon as practicable after the date of this Agreement,
Quintiles shall prepare for filing with the SEC and thereafter for circulation
to Quintiles' shareholders a proxy statement relating to the transactions
contemplated by this Agreement and the other Transaction Documents, and in
particular to the approval by such shareholders of the issuance of the
Quintiles Shares, as required by The Nasdaq Stock Market as a condition for
continued listing thereon.  Quintiles shall cause such proxy statement to
comply (except as to information supplied by Innovex or any Shareholder, to
which information this covenant does not apply) with the applicable
requirements of (i) the Exchange Act, including without limitation, Sections
14(a) and 14(d) thereof and the respective regulations promulgated thereunder
and (ii) The Nasdaq Stock Market.

                 (b)  The information supplied by Innovex, any Innovex
Subsidiary or any Shareholder for inclusion in any Filing (as defined in
Section 7.6 below) will not, at the time the filing is made, contain any untrue
statement of a material fact or omit to state a material fact necessary in
order to make the statements contained therein not misleading.  Innovex shall
ensure that each Filing meets and complies in all material respects with all
applicable Laws, including all applicable rules





                                       32
<PAGE>   38

under the Securities Act or the Exchange Act, as such Filing relates to
Innovex, any Innovex Subsidiary or any Shareholder.

                 (c)  Quintiles shall call and hold a stockholders' meeting as
promptly as practicable for the purpose of voting upon the issuance of the
Quintiles Shares hereunder, and Quintiles shall use its best efforts (through
its agents or otherwise) to solicit from its stockholders proxies in favor of
the approval of such issuance, and shall take all other action necessary or
advisable to secure the affirmative vote of its stockholders required by
applicable law to secure such approval.  The Proxy Statement shall include the
unanimous and unconditional recommendation of the Board of Directors of
Quintiles to the stockholders of Quintiles that they approve the issuance of
the Quintiles Shares contemplated by this Agreement.  In addition, the Proxy
Statement will include the opinions of Goldman Sachs & Co. and Smith Barney
Inc. referred to in Section 3.17.

         4.6.    Pooling Letter.  On or prior to the Closing Date, Innovex
shall cause to be executed and delivered to Quintiles' accountants a letter or
letters, dated the Closing Date, in form and substance reasonably satisfactory
to Quintiles and its accountants relating to "pooling of interests" accounting.

         4.7.    Redemption of Loan Notes.  On or prior to the Closing Date,
Innovex shall satisfy in full and retire all of Innovex's issued and
outstanding loan notes (as described in Schedule 2.16) in accordance with the
terms thereof, such that none shall remain issued or outstanding thereafter.

         4.8.    Directors' and Officers' Indemnification and Insurance.

                 (a) For a period of six years after the Closing, Quintiles
shall cause to be maintained in effect the current directors' and officers'
liability insurance policies maintained by Innovex (provided that Quintiles
may, and in the event of the cancellation or termination of such policies,
shall substitute therefor policies reasonably satisfactory to the indemnified
parties of at least the same coverage containing terms and conditions which are
no less advantageous) with respect to claims arising from facts or events that
occurred prior to the Closing; provided, however, that Quintiles shall not be
required to maintain such insurance if it becomes unavailable on ordinary
commercial terms or if its cost of such insurance would exceed 115% of its
current cost (in which case the beneficiaries shall be given the opportunity to
pay the difference).

                 (b)  This Section 4.8 is intended to be for the benefit of,
and shall be enforceable by, the indemnified parties, their heirs and personal
representatives, and shall be binding on Quintiles and its successors and
assigns.

         4.9.    Tax Covenant.  As described in Section 1.5, it is the intent
of the parties that the Exchange be treated as a taxable transaction for United
States Federal income tax purposes.  If,





                                       33
<PAGE>   39

prior to the Closing, Quintiles determines that the Exchange may not be so
treated, then Innovex and Quintiles shall work together in good faith to modify
the transactions contemplated hereby, if feasible, to effectuate such intent.
Notwithstanding the foregoing, no such modification shall be made pursuant to
this Section 4.9 if such modification would change the material economic terms
of the transactions contemplated by this Agreement, result in the Exchange
being taxable to a holder of Innovex Shares who is resident in the United
Kingdom for United Kingdom tax purposes, or result in the transactions
contemplated hereby being treated other than as a "pooling transaction" under
United States Generally Accepted Accounting Principles.

         4.10.   Innovex Obligations.  The Management Shareholders shall cause
Innovex to perform fully its obligations under this Agreement.

         4.11.   Reorganization.  Notwithstanding the provisions of Section
4.1, as soon as practicable after the date of this Agreement, Innovex agrees,
and the Management Shareholders agree to cause Innovex, to implement a capital
reorganization pursuant to which Innovex shall issue to the Shareholders on a
pro rata basis shares of a new class or classes of foreign currency denominated
stock (collectively, the "New Shares") which shall carry substantially all of
the rights attaching to the Innovex Shares on the date of this Agreement and
shall be represented by share warrants to bearer, and the Innovex Shares shall
be converted into a single class or classes of deferred shares, each such share
carrying a right to an annual dividend equal to 0.001% of the nominal value of
the shares and be subject to the right of Innovex to buy the share at its
market value, provided that Innovex and the Shareholders shall have received
the tax clearance letters referred to in Section 6.7, taking into account the
proposed reorganization and provided that, prior to such reorganization,
Quintiles shall have agreed to indemnify the Shareholders and Innovex to their
reasonable satisfaction against: (i) any tax liabilities they may incur which
would not have arisen in the absence of such reorganization; (ii) the costs of
effecting a further reorganization to reverse the effects of the first
reorganization should Closing not occur; and (iii) any tax liabilities which
would not have arisen in the absence of such further reorganization.  Upon such
reorganization, this Agreement shall be deemed amended to provide for the
exchange of all the New Shares, in lieu of the Innovex Shares, on the same
terms and conditions as set forth in Article I hereof, and as promptly as
practicable thereafter the parties shall enter into a written amendment to this
Agreement and take such other actions as may be necessary and appropriate to
effectuate the matters contemplated by this Section, to the reasonable
satisfaction of Quintiles.

         4.12.   Best Efforts.  Each of the Shareholders, Innovex and Quintiles
shall use their respective best efforts in good faith to satisfy the various
conditions to Closing and to consummate the Exchange by November 30, 1996.

         7.1.    Non-Interference; Confidentiality.  Each Shareholder agrees
that from the Closing until the third anniversary thereof, such Shareholder
shall not:

                 (a)      directly or indirectly, solicit, interfere with

Quintiles any customer, supplier, or other Person who or which has at any time
during the three (3) years immediately preceding the date of this Agreement or
at any time during which such Shareholder was an employee of or consultant to
Innovex done business with Innovex or Quintiles; provided that nothing herein

respective Affiliates from making investments in companies in the ordinary
course of its business; or

                 (b)      use for any purpose or knowingly divulge, directly or
indirectly, to any Person, any material information concerning Innovex's or
Quintiles' proprietary records, formulae, computer programming techniques,

standard operating procedures and practices, materials or plans, client list or
any other of Innovex's or Quintiles' trade secrets, confidential information,
price lists or pricing policies, except information which is (i) in the public
domain or (ii) becomes public knowledge through no fault of such Shareholder or
(iii) is required to be disclosed by court order or other government process or
the disclosure of which is necessary to enable such Shareholder to comply with
applicable Law or defend against claims.  In the event that such Shareholder
shall be required to make disclosure pursuant to the provisions of clause (iii)
of the preceding sentence, such Shareholder shall promptly notify Innovex and
Quintiles and take, at the expense of Innovex or Quintiles, all reasonably
necessary steps requested by Innovex or Quintiles to defend against the





                                       39
<PAGE>   45

enforcement of such court order or other government process, and permit Innovex
and Quintiles to participate with counsel of its choice in any proceeding
relating to the enforcement thereof.

         It is the desire and intent of the parties to this Agreement that the
provisions of this Section 7.1 shall be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought.  If any particular provisions or portion of this
Section 7.1 shall be adjudicated to be invalid or unenforceable, this Section
shall be deemed amended to delete therefrom such provision or portion
adjudicated to be invalid or unenforceable, such amendment to apply only with
respect to the operation of such Section in the particular jurisdiction in
which such adjudication is made.

         The parties recognize that the performance of the obligations under
this Section 7.1 by each of the Shareholders is special, unique and
extraordinary in character, and that in the event of the breach by any such
Shareholder of the terms and conditions of this Section 7.1 to be performed,
Quintiles shall be entitled, if it so elects, to institute and prosecute
proceedings in any court of competent jurisdiction, either in law or in equity,

                 (a)      Pooling of Interests Accounting.

                          (i)     Each party to this Agreement agrees that from
and after the date of this Agreement, such party shall not take any action, or
knowingly fail to take any action, which action or failure is reasonably likely
to disqualify the transactions contemplated by this Agreement from pooling of
interests accounting treatment by Quintiles, and that such party shall take all
reasonable actions necessary to cause the transactions contemplated by this
Agreement to qualify as a pooling of interests if such characterization shall
be jeopardized by action taken by such party.  Without limiting with the
foregoing, each Shareholder agrees that such Shareholder shall not sell,
transfer, pledge, or otherwise dispose of such Shareholder's interests in or
reduce such Shareholder's risk relative to any of the Quintiles Shares until
Quintiles shall have published financial results covering at least thirty (30)
days of combined operations of Quintiles and Innovex after consummation of the
transactions contemplated by this Agreement.  Each of the Shareholders and
Innovex acknowledge and agree with Quintiles that none of the Shareholders or
Innovex is a party to any agreement or arrangement among themselves or with
third parties





                                       40

regarding the transactions contemplated by this Agreement and the other

Quintiles' reasonable judgment, affiliates of Quintiles within the meaning of

accounting treatment (each such persons, a "Pooling Affiliate").  Quintiles
also shall provide Innovex with such information and documents as Innovex shall
reasonably request for purposes of reviewing such list. Prior to the Closing,
Quintiles shall deliver to Innovex an affiliate letter, in form and substance
reasonably satisfactory to Innovex, executed by each of the Pooling Affiliates
identified in the foregoing list.

                          (iii)   Prior to the Closing, Innovex shall deliver
to Quintiles a list of names and addresses of those persons who are or may be,
in Innovex's reasonable judgment, Pooling Affiliates of Innovex.  Innovex also
shall provide Quintiles with such information and documents as Quintiles shall
reasonably request for purposes of reviewing such list.  Prior to the Closing,
Innovex shall deliver to Quintiles an affiliate letter, in form and substance
reasonably satisfactory to Quintiles, executed by each of the Pooling
Affiliates of Innovex identified in the foregoing list.

                 (b)      Tax Treatment.  From and after the date of this
Agreement, each party to this Agreement shall take all reasonable actions
necessary to cause the transactions contemplated by this Agreement to qualify
as a tax-free rollover pursuant to United Kingdom tax law and as a taxable
acquisition of the Innovex Shares by Quintiles for purposes of United States
Federal income tax law.

                 (c)      Private Placement Participants

                          (i)  Each certificate representing Quintiles Shares

"Private Placement Participant") shall include the following legend:

                 THIS SECURITY HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER
THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
WITH ANY SECURITIES REGULATORY AUTHORITY OF ANY STATE OF THE UNITED STATES OR
OTHER JURISDICTION.  NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION
HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, OR
OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION EXCEPT PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, SUCH REGISTRATION





                                       41
<PAGE>   47

REQUIREMENTS.  IN THE CASE OF ANY TRANSFER OR OTHER DISPOSITION MADE OTHERWISE
THAN PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT,
THE HOLDER HEREOF SHALL BE REQUIRED TO PROVIDE TO THE ISSUER HEREOF AN OPINION
OF COUNSEL SATISFACTORY TO THE  ISSUER THAT SUCH TRANSFER IS EXEMPT FROM, OR
NOT SUBJECT TO, REGISTRATION UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH
ALL APPLICABLE STATE SECURITIES LAWS, AND AN AGREEMENT BY THE TRANSFEREE TO BE
BOUND BY THE TRANSFER RESTRICTIONS SET FORTH IN THE AGREEMENT PURSUANT TO WHICH
THIS SECURITY WAS FIRST SOLD BY THE ISSUER.

                          (ii)    Each Private Placement Participant
individually represents, warrants and covenants as follows:

                                  (A)      Such Private Placement Participant

Placement Participant in reliance on an exemption from the registration
requirements of the Securities Act for an offer and sale of securities that
does not involve a public offering and have not been registered under the
Securities Act or with any securities regulatory authority of any state of the
United States or other jurisdiction and, therefore, that such Quintiles Shares
(and all securities issued in exchange therefor or in substitution thereof)
cannot be resold in the absence of such registration except pursuant to an
exemption from, or in a transaction not subject to, such registration
requirements.  Such Private Placement Participant agrees that it shall not
transfer any Quintiles Shares except in a transaction registered under the
Securities Act or unless such Private Placement Participant shall have
delivered to Quintiles an opinion of United States counsel, which counsel and
opinion shall be reasonably satisfactory to Quintiles, that such transfer is
being effected in accordance with an available exemption from, or in a
transaction not subject to, the registration requirements of the Securities Act
and a written instrument, in form and substance reasonably satisfactory to
Quintiles, from the transferee agreeing to be bound hereby.  Such Private
Placement Participant is aware that Quintiles is under no obligation to effect
any such registration under the Securities Act or otherwise with respect to
such Quintiles Shares (or any securities issued in exchange thereof or in
substitution thereof) or to file for or comply with any exemption from such
registration except as set forth in the Registration Rights Agreement.

                                  (B)      Such Private Placement Participant
is an "accredited investor" (as defined in Regulation D under the Securities
Act), with such knowledge and experience in financial and business matters as
are necessary in order to evaluate the merits and risks of any investment in
the Quintiles Shares.

                                  (C)      Such Private Placement Participant
will acquire the Quintiles Shares for its own account and not with a view to
any distribution (within the meaning of the Securities Act) thereof or with any
present intention of offering or selling any of the Quintiles





                                       42
<PAGE>   48

Shares in a transaction that would violate the Securities Act or the securities
Laws of any state of the United States or any other applicable jurisdiction.

                                  (D)      Such Private Placement Participant
acknowledges that any resale or other transfer, or attempted resale or other
transfer, made other than in compliance with the restrictions stated herein
shall not be recognized by Quintiles in respect of the Quintiles Shares, and
that Quintiles may deliver a corresponding stop-transfer order to its transfer
agent (the "Transfer Agent") to that effect.

                                  (E)      Such Private Placement Participant
has not engaged, and during the Restricted Period (as defined below) will not
engage, in any "directed selling efforts" (as defined below) with respect to
the Quintiles Shares.

                          (iii)   Quintiles shall, upon the written request of
a Private Placement Participant to remove the legend set forth in subsection
(c)(i), together with delivery to Quintiles of an opinion of counsel to such
Private Placement Participant, which counsel and opinion shall be reasonably

longer "restricted securities" within the meaning of Rule 144 under the
Securities Act and that such legend is no longer required on the certificate or
certificates evidencing such Quintiles Shares under the applicable requirements
of the Securities Act or applicable state securities or "blue sky" Laws, direct
its transfer agent to issue a certificate representing such Quintiles Shares
without such legend upon surrender to the Transfer Agent of the certificate
with such legend.

                 (d)  Regulation S Participants

                          (i)     Each certificate representing Quintiles
Shares delivered to any Shareholder identified as a Regulation S participant on
Exhibit A (each such Shareholder, together with any permitted transferee, a
"Regulation S Participant") shall include the following legend:

                 THIS SECURITY HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER
THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
WITH ANY SECURITIES REGULATORY AUTHORITY OF ANY STATE OF THE UNITED STATES OR
OTHER JURISDICTION.  NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION
HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, OR
OTHERWISE DISPOSED OF PRIOR TO THE EXPIRATION OF A RESTRICTED PERIOD (DEFINED
AS 40 DAYS AFTER THE CLOSING DATE OF THE SHARE EXCHANGE AGREEMENT AMONG THE
ISSUER, INNOVEX LIMITED AND OTHERS ("THE SHARE EXCHANGE AGREEMENT")) EXCEPT IN
AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT
AND IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE
UNITED STATES AND OF ANY OTHER JURISDICTION.  IN ADDITION, NO SUCH DISPOSITION





                                       43
<PAGE>   49

MAY BE MADE UNLESS PRIOR TO SUCH TRANSFER THE HOLDER AND PROPOSED TRANSFEREE
DELIVER TO THE ISSUER CERTAIN CERTIFICATIONS AND OPINIONS OF COUNSEL AND THE
PROPOSED TRANSFEREE MAKES CERTAIN REPRESENTATIONS AND WARRANTIES AND AGREES TO
CERTAIN COVENANTS, ALL AS SET FORTH IN THE SHARE EXCHANGE AGREEMENT.

                 UPON THE EXPIRATION OF THE RESTRICTED PERIOD (AS DEFINED
ABOVE), THIS SECURITY SHALL NO LONGER BE SUBJECT TO THE RESTRICTIONS PROVIDED
IN THIS LEGEND, IF AT THE TIME OF SUCH EXPIRATION THIS SECURITY WOULD NOT BE
RESTRICTED UNDER THE SECURITIES LAWS OF THE UNITED STATES OR ANY STATE OF THE
UNITED STATES.

                          (ii)     Each Regulation S Participant and each
purchaser of Quintiles Shares in subsequent resales prior to the end of the
Restricted Period referred to below, individually represents, warrants and
covenants (or shall be deemed to have represented, warranted and covenanted, if
not a party to this Agreement) as follows:

                                  (A)      Such Regulation S Participant
understands that the Quintiles Shares are being issued to such Regulation S
Participant in reliance on Regulation S promulgated pursuant to the Securities
Act ("Regulation S") and have not been registered under the Securities Act or
with any securities regulatory authority of any state of the United States or
other jurisdiction and, therefore, that such Quintiles Shares (and all
securities issued in exchange therefor or in substitution thereof) cannot be
resold in the absence of such registration except pursuant to an exemption
from, or in a transaction not subject to, such registration requirements.  Such
Regulation S Participant is aware that Quintiles is under no obligation to
effect any such registration under the Securities Act or otherwise with respect
to such Quintiles Shares (or any securities issued in exchange therefor or in
substitution thereof), or to file for or comply with any exemption from such
registration except as set forth in the Registration Rights Agreement.

                                  (B)      Such Regulation S Participant is,

the initial Regulation S Participants, this Agreement was executed, and the
investment decision to enter into this Agreement was made, outside the United
States.

                                  (C)      Such Regulation S Participant is not
in the business of buying and selling securities or, if it is in such business,
it did not acquire the Quintiles Shares from Quintiles or an affiliate thereof
in the initial distribution of Quintiles Shares.

                                  (D)      Such Regulation S Participant will
not offer, sell or deliver any of the Quintiles Shares until 40 Days after the
Closing Date (the "Restricted Period") except in an





                                       44
<PAGE>   50

"offshore transaction" (as defined in Regulation S) in accordance with Rule 904
of Regulation S and in accordance with this Agreement.

                                  (E)      Such Regulation S Participant has
not and will not, until the expiration of the Restricted Period, directly or
indirectly, execute or effect any short sale, option or equity swap
transactions in or relating to the Quintiles Shares or any other derivative
securities transactions the purpose or effect of which is to transfer to a
third party all or any part of the risk of loss associated with the Quintiles
Shares to be acquired by the Regulation S Participant.

                                  (F)      Such Regulation S Participant
acknowledges that any resale or other transfer, or attempted resale or other
transfer, which Quintiles determines in good faith was made other than in
compliance with the restrictions stated herein shall not be recognized by
Quintiles in respect of such Quintiles Shares, and that Quintiles may deliver a
corresponding stop-transfer order to the Transfer Agent to that effect.

                                  (G)      The certificates representing the
Quintiles Shares to be delivered to the Regulation S Participants will be
delivered to Goldman Sachs International, as each Regulation S Participant's
representative, to be held in custody for delivery to each Regulation S
Participant within 5 business days after the "Delivery Date", which will be the
first business day after the expiration of the Restricted Period.  If a
Regulation S Participant intends to transfer any of the Quintiles Shares or an
interest or participation therein prior to the Delivery Date, the Regulation S
Participant shall  deliver to Quintiles (i) a written certificate that neither
record nor beneficial ownership of the shares evidenced thereby has been
offered or sold in the United States, or to or for the account or benefit of a
"U.S. person" (as defined in Regulation S), (ii) a written certification of the
proposed transferee in form and substance reasonably satisfactory to Quintiles
that such transferee is not a "U.S. person" or acquiring such Quintiles Shares
for the account or benefit of  a "U.S. person", and that such transferee is
knowledgeable of and agrees to be bound by the restrictions on transfer and
derivative activities set forth herein during the Restricted Period and (iii) a
written opinion of counsel to the transferee, which counsel and opinion shall
be reasonably satisfactory to Quintiles, to the effect that the offer, sale and
transfer of the Quintiles Shares are not subject to registration under the
Securities Act, upon delivery of which Quintiles shall instruct Goldman Sachs
International to deliver such Regulation S Participant's certificate(s)
thereto.  Any Regulation S Participant may obtain a certificate for the
Quintiles Shares without the legend set forth in subsection (d)(i) hereof from
the Transfer Agent after the Delivery Date upon surrender to the Transfer Agent
of the certificate representing the relevant Quintiles Shares.

                                  (H)      Such Regulation S Participant has
not engaged in, and during the Restricted Period will not engage in, any
"directed selling efforts" (as defined in Regulation S) with respect to the
Quintiles Shares.

                 (e)  Innovex Representations, Warranties and Covenants with
Respect to Placement of Quintiles Shares.

                          (i)     Neither Innovex nor any of its Affiliates,
nor any Person acting on its or their behalf has made or will make, directly or
indirectly, offers or sales of any security, or has solicited or will solicit
offers to buy any security, under circumstances that would require the
registration under the Securities Act of the issuance of the Quintiles Shares
hereunder.

                          (ii)    Neither Innovex, nor any of its Affiliates,
nor any Person acting on its or their behalf has engaged in or will engage in
any form of general solicitation or general advertising (within the meaning of
Regulation D under the Securities Act) in connection with the issuance of the
Quintiles Shares hereunder.

                          (iii)   Innovex has not engaged, and during the
Restricted Period will not engage, in any "directed selling efforts" (as
defined in Regulation S under the Securities Act) with respect to the Quintiles
Shares.

         7.3.    Non-Solicitation.  Each of Quintiles (for itself and its
Subsidiaries) and Innovex (for itself and its Subsidiaries) agrees that between
the date of this Agreement and the earlier to occur of the Closing and the date
on which this Agreement is terminated pursuant to its terms, it shall not
solicit, induce or recruit any of the other's employees to leave their
respective employment.

         7.4.    Management Issues.

                 (a)      Board of Directors.  As soon as practicable after the
Closing, Quintiles shall cause Barrie S. Haigh and Paul Knott to be designated
as  directors of Quintiles and cause Barrie S. Haigh to be designated as
Vice-Chairman of Quintiles' board of directors, such designations to be
effective as of the first meeting of Quintiles' board of directors subsequent
to the Closing.  Innovex may also nominate up to one additional person for
election as a non-executive member of Quintiles' board of directors, such
nomination to be presented to the first meeting of Quintiles' shareholders
subsequent to the Closing.  Paul Knott also shall become an employee of
Quintiles and report to the Chief Financial Officer of Quintiles.

                 (b)      Executive Management Committee.  As soon as
practicable after the Closing, Quintiles shall reconstitute the membership of
its Executive Management Committee to include executive officers at the
Quintiles Corporate level (including the Chairman, Vice-Chairman, COO, CFO and
EVP) and two executives from each of the three divisions described below in
Section 7.4(c)(i).  David White and David Stack will be appointed to the
Executive Management Committee commencing the first meeting after the Closing

Management Committee in his capacity as Vice





                                       46
<PAGE>   52

Chairman, representing Quintiles' overall business development interests.
Quintiles' Chief Operating Officer shall chair the Executive Management
Committee.

                 (c)      Preservation of Innovex Identity.

                          (i)     Divisional Status.  Innovex (together with
its Subsidiaries) shall continue its separate corporate existence, operating
under the name "Innovex, a division of Quintiles Transnational Corp." (the
"Innovex Division").  It is understood and acknowledged by the parties that two
further divisions of Quintiles will also be formed subsequent to the Closing,
comprising the Quintiles division (focusing on clinical research) and the Lewin
division (concentrating on managed care).

                          (ii)    Strategic Focus.  The Innovex Division will
have the strategic focus of supplying outsourcing services to the
pharmaceutical industry during the product peri-launch period (the two years
before and the two years subsequent to the receipt of regulatory approval for
customers' pharmaceutical products).  It is understood and acknowledged by the
parties hereto that the strategic focus of the Innovex Division encompasses,
among other things, (A) Phase IIIb and Phase IV clinical testing, as well as
large simple trials of pharmaceutical products, (B) disease management services
and related added-value marketing services, (C) sales services and (D)
marketing and distribution services.  It is understood, however, that clinical
and disease management functions may be coordinated or combined with the other
divisions as appropriate.

                          (iii)   Divisional Management.  Each of the Innovex
Division, the Quintiles division and the Lewin division will create its own
executive management team.  The CEO of the Innovex Division shall report to the
COO of Quintiles.

                          (iv)    Announcements.  Consistent with the aim of
preserving Innovex's separate identity, any press announcement by Quintiles or
Innovex regarding this Agreement, the other Transaction Documents or the
transactions contemplated hereby or thereby, will refer to such transactions as
a financial pooling and/or a business combination.

                 (d)      Steering Committee.  Upon the execution and delivery
of this Agreement, Quintiles and Innovex will establish a committee (the
"Steering Committee") for the purpose of, to the extent permitted by applicable
law, advising executive management and further facilitating the efficient
combination of the respective businesses of Quintiles and Innovex as promptly
as practicable following the Closing.  The Steering Committee will initially
consist of a number of integration teams comprising, in aggregate, 34 members,
17 of whom will be designated by Quintiles and 17 of whom will be designated by
Innovex.





                                       47

                 (e)      Business Development Function.  Upon the execution
and delivery of this Agreement, Quintiles and Innovex will establish a business
development matrix organization (the "Business Development Function") for the
purpose of developing increased business subsequent to the Closing through the
coordination of all client relationships.  The Business Development Function
will involve all business development personnel in each division of Quintiles
and will report to the Vice Chairman.


                 (f)      Employees.  Each person who is an officer or employee
of Innovex (or any of its Subsidiaries) shall, after the Closing, remain an
employee of the Innovex Division, until such person's employment is terminated.
Nothing herein shall be deemed or construed to give rise to a right of
employment.  As of the Closing, Quintiles will offer employee benefit plans and
programs to employees who continue in the employ, or become employed by, the
Innovex Division that, taken as a whole, are comparable to the employee benefit
plans and programs provided to employees of Innovex as of the date hereof
(except as otherwise provided herein); provided, however, that the terms and
conditions of such employee benefit plans and programs may be varied or
eliminated at any time subsequent to the first anniversary of the Closing Date
in a manner determined by the Compensation Committee of Quintiles Board of
Directors, the members of which shall be comprised of a majority of external
directors.

                 (g)      Duration and Effect.  The provisions of this Section
7.4 represent the current intent of Quintiles, and Quintiles will exercise good
faith efforts to comply with the provisions of this Section 7.4 for a period of
18 months after the Closing (or any shorter period specified herein.)
Notwithstanding anything to the contrary herein, it is understood that
Quintiles retains ample discretion to manage its business in the best interests
of its shareholders, and that good faith modifications of or variances from
these provisions in the exercise of such discretion are appropriate and
permitted.  Accordingly, except as to employee benefits as set forth in Section
7.4(f) above, the provisions of this Section 7.4 are unenforceable and only an
expression of current intent.

         7.5.    No Acquisition of Quintiles Shares.  Except with Quintiles'
prior written consent, neither Innovex, any Shareholder, nor any of their
respective Affiliates shall purchase or otherwise acquire, directly or
indirectly, any securities of Quintiles during the period from the date of this
Agreement until the Closing; provided that, subject to Section 7.2(a)(i) this
provision will not prevent any Shareholder that is an institutional trustee or
any affiliate of any Shareholder (other than a Management Shareholder) from
purchasing and selling securities in the ordinary course of its business not
with a view towards controlling Quintiles.

         7.6.    Cooperation with Securities Filings.  Innovex and the
Shareholders will cooperate, and will cause their respective financial,
accounting and legal advisors to cooperate, with Quintiles





                                       48
<PAGE>   54

in the preparation and filing of all documents and materials (each a "Filing")
required or elected to be disclosed or reported by Quintiles pursuant to
applicable securities Laws in connection with the transactions contemplated by
this Agreement and the other Transaction Documents or to the extent otherwise
relating to or concerning Innovex or any Shareholder, including without
limitation Quintiles' definitive proxy statement relating to the Exchange and
Quintiles' registration statement on Form S-4 relating to Quintiles' pending
transaction with BRI International, Inc.  To that end, Innovex and the
Shareholders shall furnish to Quintiles, as promptly as is practicable after
Quintiles' request therefor, such data and information relating to Innovex, the
Innovex Subsidiaries and the Shareholders and such financial statements of
Innovex and the Innovex Subsidiaries and opinions, comfort letters and consents
of independent certified public accountants relating thereto as, in the opinion
of counsel for Quintiles, shall be required by Law to be disclosed or reported
by Quintiles or as are otherwise determined by Quintiles to be reasonably
necessary or appropriate in connection therewith.  Quintiles shall provide a
draft of each Filing to Innovex promptly following the preparation thereof.
Innovex shall approve all disclosures concerning Innovex, any Innovex
Subsidiary or any Shareholder in each Filing (or shall notify Quintiles of any
changes requested in such disclosures) promptly following receipt of the
corresponding draft from Quintiles.  In the event that Innovex shall not have
responded as promptly as reasonably practical to the delivery of any draft
Filing by Quintiles, Innovex shall be deemed to have approved any disclosures
concerning Innovex, any Innovex Subsidiary or any Shareholder in such Filing.
If, at any time prior to the Closing, any event should occur relating to
Innovex, any Innovex Subsidiary or any Shareholder which should be set forth in
an amendment of, or a supplement to, any Filing, Innovex will promptly inform
Quintiles.

         7.7.    Nasdaq National Market Listing.  Quintiles shall use its best
efforts to cause Quintiles Shares to be approved for listing on the Nasdaq
National Market, subject to official notice of issuance, prior to the Closing
Date.


                                  ARTICLE VIII
                     SURVIVAL OF REPRESENTATIONS; INDEMNITY

         8.1.    Survival of Representations.  The respective representations
and warranties of the Shareholders contained in this Agreement or in any
schedule attached hereto shall survive the consummation of the Exchange and the
other transactions contemplated hereby and shall remain in full force and
effect notwithstanding any investigation or examination of, or knowledge with
respect to, the subject matter thereof by or on behalf of Quintiles until the
earlier of the closing of the Initial Secondary Offering (as defined in the
Registration Rights Agreement) or March 31, 1997 (the period ending on such
earlier date being referred to herein as the "Representations Period"), except
that such representations and warranties shall survive indefinitely in the
event of fraud with respect thereto.  No claim for indemnification pursuant to
Section 8.2(a) below may be





                                       49
<PAGE>   55

brought after the expiration of the Representations Period, except for claims
made in good faith in writing and setting forth in reasonable detail the claim
prior to such expiration or actions (whether instituted before or after such
expiration) based on any claims made in good faith in writing and setting forth
in reasonable detail the claim prior to such expiration, regardless of whether
any action or demand has been commenced against Quintiles (it being understood,
without limitation, that any and all Losses arising after the expiration of the
Representations Period shall be recoverable upon notice properly given prior to
the expiration of the Representations Period in accordance with this Section
8.1).  The representations and warranties of Quintiles contained in this
Agreement or in any schedule attached hereto shall terminate upon and  not
survive the consummation of the Exchange, except in the event of fraud by
Quintiles with respect thereto, in which case they shall survive indefinitely.

         8.2.    Indemnification.

                 (a)      From and after the Closing, Quintiles and its
Affiliates (including Innovex  and its Subsidiaries) and all of their
respective officers, directors, employees (other than the Key Employees),
agents and shareholders (other than the Shareholders) (each, an "Indemnitee")
shall be defended, indemnified and held harmless pursuant to this Agreement and
the Escrow Agreement to the full extent permitted in law or equity, from and
against any and all losses, claims, actions, damages, liabilities, costs and
expenses (including attorneys' fees and expenses) (collectively, "Losses")
relating to or arising from or in connection with (i) any misrepresentation or
any non- fulfillment of any representation, warranty, covenant, obligation or
agreement by Innovex or any Shareholder contained in or made pursuant to this
Agreement or any of the other Transaction Documents or in any other agreement,
officer's certificate or other certificate delivered to Quintiles in connection
with this Agreement, and (ii) the enforcement by Quintiles of its rights
pursuant to this Section 8.2, or any litigation, proceeding or investigation
relating to any of the foregoing.

                 (b)      Notwithstanding the foregoing provisions of this
Section 8.2, and except with respect to any misrepresentation or
non-fulfillment of the representations and warranties in Section 2.1 above and
in the last sentence of Section 2.26 above or any breach of any post-Closing
covenant contained in Article VII above, or any Losses resulting from or
arising out of fraud or other intentional or knowing misconduct or
misrepresentation, as to which (in each case) the party or parties breaching
such representation, warranty or covenant or responsible for such fraud,
misconduct or misrepresentation shall be jointly and severally liable to
Quintiles without limitation, (i) the maximum aggregate recourse by the
Indemnitees pursuant to subsection (a) above shall not exceed the aggregate
value (calculated with reference to closing prices on the Closing Date) of the
Escrow Fund (the "Indemnity Cap"), (ii)   the Indemnitees shall not be entitled
to indemnification under subsection (a) above for any amount unless and until
the aggregate of all amounts for which the Indemnitees otherwise would be
entitled to be indemnified exceeds





                                       50
<PAGE>   56

$750,000 (in the aggregate), after which the Indemnitees shall be indemnified
in full for the excess, up to the Indemnity Cap, and (iii) the sole monetary
recourse of any Indemnitee in respect or Losses described in subsection (a)
above (but not in respect of any other claim) shall be from, out of, and to the
extent of the Escrow Fund.  For purposes of determining whether the aggregate
of all amounts for which the Indemnitees would otherwise be entitled to be
indemnified exceeds $750,000, the amount of each indemnifiable claim and the
aggregate amount of all indemnifiable claims shall not be limited by the use of
the term "material" or its related forms in any representations or warranties,
or by the establishment of any dollar threshold in any representation or
warranty for inclusion of any event or matter therein.  Accordingly,
indemnifiable claims may consist of Losses (whether or not arising from a
breach of an individual representation, warranty, covenant or indemnity) that
individually or in the aggregate do not constitute material amounts or amounts
in excess of specified thresholds, provided such amounts in the aggregate
exceed $750,000.

                 (c)      Notwithstanding any other provision of this
Agreement:

                          (i)     as of and after the Closing, Innovex shall
have no liability under this Agreement, and no Shareholder shall threaten or
bring any claim or action whatsoever against Innovex for contribution to any
amounts payable under this Section 8.2 by such Shareholders.

                          (ii)    in the event that the Agreement is terminated
by Quintiles following a breach of a representation by Innovex in this
Agreement, Innovex's liability shall be limited to the out-of-pocket expenses
incurred by Quintiles.  Innovex shall have no liability at all to Quintiles for
breach of Section 2.1(a), the last sentence of Section 2.26, or Sections 2.27
or 2.28 (as Sections 2.27 and 2.28 relate to the Shareholders).  Furthermore,
Innovex shall only have liability if the representations given by Innovex are
breached after the date hereof by reason of its own neglect or default.

                          (iii)    the maximum liability of any Shareholder
that is a trustee of a trust the assets of which include Innovex Shares shall
be limited to the value of the trust assets held by them directly or indirectly
as trustees of the relevant trust; provided that this limitation on the
liability of the trustees shall not apply for the benefit of any trustee in the
event of a deliberate or reckless breach by that trustee of any of its
obligations under this Agreement.

                 (d)      Except as expressly set forth elsewhere in this
Agreement or to the extent of the application of the nonbreaching Shareholder's
interest in the Escrow Fund, no nonbreaching Shareholder will suffer any
liability for a breach of this Agreement by any other party.

         9.11.   Entire Agreement.  This Agreement, including the other
documents referred to herein which form a part hereof and together with the
confidentiality agreement referred to below, contains the entire understanding
of the parties hereto with respect to the subject matter contained herein and

between the parties with respect to such subject matter except for that certain
Confidential Disclosure Agreement dated June 3, 1996 between  Innovex and
Quintiles which shall remain in full force and affect and shall not be limited
or otherwise affected hereby.  All exhibits and schedules referred to in this
Agreement are intended to be and hereby are specifically made a part of this
Agreement.

         9.12.   Construction of Certain Disclosures.  No information disclosed
in any schedule to this Agreement shall be deemed to be disclosed for purposes
of any other section hereof or schedule hereto unless otherwise specifically
stated therein.  The representations and warranties set forth in Articles II
and III above, respectively, are cumulative.  The subject matter covered by any
section of either such article shall not be exclusive as to such subject matter
to the extent covered by another section of such article, and the specificity
of any representation or warranty shall not affect or limit the generality of
any other representation or warranty made or given by the same party.

         9.13.   Amendments.  Except as otherwise provided herein, this
Agreement may be waived, amended, supplemented or modified only by a written
agreement executed by each of the parties hereto.

         9.14.   Severability.  In case any provision in this Agreement shall
be held invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions hereof will not in any way be
affected or impaired thereby.

         9.15.   Third Party Beneficiaries.  Except as otherwise provided by
Section 8.2, each party hereto intends that this Agreement shall not benefit or
create any right or cause of action in or on behalf of any Person other than
the parties hereto.

         9.16.   Termination of Agreement.  The parties hereto shall be
entitled to terminate this Agreement as follows, provided that (i) no such
termination shall limit or terminate any liability of





                                       56
<PAGE>   62

one party to another for any breach hereof, (ii) the provisions of Sections 7.1
(confidentiality), 8.2 (indemnification), 9.2 (expenses) and 9.7 (publicity)
shall survive any such termination, and (iii) in the case of a termination
below other than by Quintiles, only Innovex or one or more Shareholders holding
in excess of thirty (30%) percent of the Innovex share capital shall be
entitled to terminate this Agreement:

                 (a)      the parties hereto may terminate this Agreement by
mutual written consent at any time;

                 (b)      Quintiles may terminate this Agreement by written
notice to the Shareholders and Innovex on or prior to the Closing Date if any
Shareholder or Innovex shall have breached in any material respect any
representation, warranty or covenant contained in this Agreement;

                 (c)      Quintiles may terminate this Agreement by written
notice to the Shareholders and Innovex on or prior to the Closing Date upon a
breach of Section 4.2 above;

                 (d)      Quintiles or Innovex may terminate this Agreement by
written notice to the parties hereto if the consummation of the transactions
contemplated hereby shall not have occurred on or before December 31, 1996; and

                 (e)      any party may terminate this Agreement by written
notice to the  other parties hereto on or prior to the Closing Date if any
court or other governmental instrumentality of competent jurisdiction shall
have issued an order, decree or ruling or taken any other action restraining,
enjoining or otherwise prohibiting the transactions contemplated by this
Agreement.

                 In the event this Agreement shall be terminated prior to the
Closing Date,  no party shall be liable to any other party under this Agreement
or otherwise except for actual out-of-pocket expenses of a non-breaching party
arising in connection with this Agreement; provided, however, that the
foregoing limitation shall not apply to any intentional breach of this
Agreement or any breach of Section 4.2; provided further that in the event
Management Shareholders and Innovex are liable for Quintiles' actual
out-of-pocket expenses, each Management Shareholder shall be liable only for
such Management Shareholder's pro rata (among Management Shareholders'
interests as a group) percentage of such out-of-pocket expenses.

hold and distribute the Escrow Certificates and Escrow Shares in accordance
with the terms hereof.

         1.3.    Value of Escrow Shares.  For all purposes pursuant to this

                                   ARTICLE II

without limitation, any certificate in connection with any increase or
reduction of capital, reclassification, recapitalization, merger, business

<PAGE>   73

the Escrow Shares; or (iii) non-taxable stock dividend or other non-taxable
distribution payable in securities or property of any description, all of the
shares of capital stock or other property resulting from any such distribution,

Shares and shall be subject to the terms hereof to the same extent as the
original Escrow Shares.  Any cash dividends and any taxable stock dividends

accordance with their respective proportionate interests in the Escrow Shares.
Each of the Shareholders shall recognize as income on a current basis all of

the Escrow Shares (as determined by the Share Exchange Agreement) and shall (to
the extent legally permissible) vote the corresponding Escrow Shares in
accordance with the written instructions of each Shareholder for whose account
such Escrow Shares are held.


                                  ARTICLE III
        DISTRIBUTION OF ESCROW SHARES UPON TERMINATION OF THE AGREEMENT

         3.1.    Deadline For Claims and Termination of Agreement.  Quintiles
shall not be entitled to assert any claim against the Escrow Shares after the
expiration of the Representations Period (as defined in Section 8.1 of the
Share Exchange Agreement), the last day of which shall be referred to herein as
the "Claims Deadline"; provided, however, that any claim made in good faith and
in writing on or prior to the Claims Deadline (whether or not formal legal
action shall yet have been commenced based upon such claim) shall continue,
subject to final resolution as provided herein.  This Agreement shall terminate
upon complete distribution of the Escrow Shares in accordance with this
Agreement.

         3.2.    Distribution of the Escrow Funds Upon Termination of the
Agreement.

                 (a)      Within five (5) business days after the Claims
Deadline, the Escrow Agent shall deliver to the Shareholders that portion of
the Escrow Shares (the "Distribution Proceeds") not previously distributed or
otherwise subject to claims pursuant to Article IV, in proportion to the
initial deposits of shares made on their behalf by Quintiles.  Thereafter, the
balance of the Escrow Shares shall continue to be held by the Escrow Agent in
accordance with the terms of this Agreement until all claims asserted against
the Escrow Shares have been finally resolved in accordance with Article IV
below; whereupon, the balance of the Escrow Shares shall be





                                       3
<PAGE>   74

distributed to the Shareholders as provided above in full discharge of the
Escrow Agent's obligations under this Agreement.

                 (b)      Notwithstanding the foregoing, in the event that
under any of the provisions contained herein, the Escrow Agent would be
required to deliver fractional interests in Escrow Shares to the Shareholders,
Quintiles shall be entitled at its option to purchase from the Escrow Agent
such a number of Escrow Shares (or fractional interests therein) as shall be
necessary to eliminate such fractional interests, at a purchase price equal to
the closing price of Quintiles' Common Stock on the Nasdaq National Market on
the Closing Date.  In such event, the Escrow Agent shall distribute to the
Shareholders who otherwise would have been entitled to fractional interests in
shares of Quintiles Stock the cash equivalent of such fractional shares (based
on the purchase price as described above).


                                   ARTICLE IV
           DELIVERY OF CAPITAL STOCK AND OTHER PROPERTY OUT OF ESCROW

         4.1.    Claims Against Escrow Shares.  If, at any time on or prior to
the Claims Deadline, Quintiles (on its own behalf or on behalf of any other
Indemnitee) shall assert a claim for indemnification pursuant to Article VIII
of the Share Exchange Agreement, Quintiles shall submit to the Escrow Agent and
to the Shareholders a written claim in good faith signed by an executive
officer of Quintiles stating:  (i) that an Indemnitee has incurred or
reasonably believes it may incur Losses and the reasonable estimate of the
amount of any such Losses; (ii) in reasonable detail, the facts alleged as the
basis for such claim and the section or sections of the Share Exchange
Agreement alleged as the basis or bases for the claim; and (iii) if the Losses
have actually been incurred, the number of Escrow Shares to which such
Indemnitee is entitled with respect to such Losses, which shall be determined
by dividing the amount thereof by the closing price per share of Quintiles'
Common Stock on the Nasdaq National Market on the Closing Date.  If the claim
is for Losses which the Indemnitee reasonably believes it may incur or is
otherwise unliquidated, the written claim of Quintiles shall state the
reasonable estimate of such Losses, in which event a claim shall be deemed to
have been asserted against the Escrow Shares on behalf of Quintiles in the
amount of such estimated Losses, but no payment or distribution shall be made
by the Escrow Agent out of the Escrow Shares until such Losses have actually
been incurred and Quintiles submits written notice to the Escrow Agent and the
Shareholders, whether or not the Losses are incurred prior to the Claims
Deadline.

         4.2.    Resolution of Asserted Claims Against the Escrow Shares.  If,
within fifteen (15) business days after Quintiles gives notice to the Escrow
Agent and the Shareholders of an asserted claim pursuant to Section 4.1 above
that an Indemnitee has incurred Losses, any Shareholder shall fail to notify
the Escrow Agent and Quintiles, in writing, that such Shareholder disputes in
good faith the right of the Indemnitee to indemnity in respect of the asserted
claim,





                                       4
<PAGE>   75

then the Escrow Agent, at the expiration of such fifteen (15) business day
period, shall make immediate payment to Quintiles, out of the Escrow Shares, of
such Shareholder's pro rata amount of the asserted claim by distributing to
Quintiles such number of Escrow Shares as have an aggregate value equal to such
Shareholder's pro rata amount of the claim.

         4.3.    Resolution of Disputed Claims Against Escrow Shares.  If,
within the fifteen (15) business day period after notice of an asserted claim
is given to the Escrow Agent and the Shareholders under Section 4.1 above, any
Shareholder shall notify the Escrow Agent and Quintiles, in writing, that such
Shareholder disputes or denies in good faith the asserted claim made by
Quintiles against the Escrow Shares, then such Shareholder and Quintiles shall
use their respective reasonable best efforts to effect a settlement and
compromise of such asserted claim.  Any liability, loss, damage or expense
established by reason of any such settlement and compromise shall be certified
in writing to the Escrow Agent by such Shareholder and Quintiles, and the
Escrow Agent shall pay to Quintiles out of the Escrow Shares the amount due and
owing to Quintiles by reason of such settlement and compromise, if any.  If any
such settlement and compromise so certified to the Escrow Agent establishes
that no amount shall be due and owing to Quintiles under the asserted claim,
then the Escrow Agent shall treat the asserted claim as rejected by mutual
agreement of the parties, and the asserted claim shall be totally disregarded
by the Escrow Agent as if never the subject of assertion against the Escrow
Shares.

         4.4.    Unresolved Claims Against Escrow Shares.  If Quintiles and any
such Shareholder are unable to settle and compromise any disputed claim
asserted against the Escrow Shares, the Escrow Agent shall not make any payment
or distribution out of the Escrow Shares with respect to such unresolved
asserted claim unless and until the Escrow Agent shall have received either:

                 (a)      a certificate signed on behalf of Quintiles and such
Shareholder certifying the amount of the asserted claim in dispute and
directing payment thereof; or

                 (b)      a certified copy of an award of an arbitrator
referred to in Article VII hereof determining the amount of the asserted claim
in dispute; or

                 (c)      a certified copy of a final, binding and
nonappealable judgment of a court of competent jurisdiction determining the
amount of the asserted claim in dispute.

Upon receipt of any such certification, the claim shall be treated as a
resolved asserted claim pursuant to Section 4.2 above and the Escrow Agent
shall pay and distribute Escrow Shares in the manner described in Section 4.2.

                                   ARTICLE V
                  RESPONSIBILITIES AND DUTIES OF ESCROW AGENT

         5.1.    Rights, Duties, Liabilities and Immunities of Escrow Agent.
Quintiles and the Shareholders hereby agree as follows with respect to the
rights, duties, liabilities and immunities of the Escrow Agent:

                 (a)      The Escrow Agent shall act as a depository only and
shall not be responsible or liable in any manner whatsoever for the
sufficiency, correctness, genuineness, or validity of the Escrow Shares
deposited with it, or any part thereof.

                 (b)      The Escrow Agent shall be protected in acting upon
any written certificate, notice, request, waiver, consent, receipt or other
paper or document furnished to it, not only as to its due execution and the
validity and effectiveness of its provisions, but also as to the truth and
acceptability of any information therein contained which the Escrow Agent in
good faith believes to be genuine and what it purports to be.

                 (c)      The Escrow Agent shall not be liable for any error of
judgment, or for any act done or steps taken or made by it in good faith, or
for any mistake of fact or law, or for any things which it may do or refrain
from doing in connection herewith, except due to the Escrow Agent's own gross
negligence or willful misconduct.

                 (d)      The Escrow Agent may consult with and obtain advice
from legal counsel in the event of any question as to any of the provisions of
this Agreement or its duties hereunder, and the Escrow Agent shall incur no
liability and shall be fully protected in acting in good faith in accordance
with the opinion and instructions of such counsel.  Subject to the provisions
of Section 5.3 hereof, the cost of such services shall be added to and shall
become a part of the Escrow Agent's compensation hereunder.

                 (e)      The Escrow Agent shall have no duties except those
expressly set forth herein, and shall not be bound by any notice of a claim or
demand with respect thereto, or any waiver, modification, amendment,
termination or rescission of this Agreement, unless in a writing received by
it, and, if its duties herein are affected, unless it shall have given its
prior written consent thereto.

                 (f)      The Escrow Agent is not a party to and is not bound
by the Share Exchange Agreement, nor is it a party to or bound by or charged
with notice of any other agreement (other than this Agreement) to which the
Escrow Shares may relate.

                 (g)      In the event of any disagreement between any of the
parties to this Agreement or between them or any one of them and any other
person resulting in adverse claims





                                       6
<PAGE>   77

or demands being made in connection with the subject matter of this Agreement,
or in the event the Escrow Agent in good faith shall be in doubt as to what
action it should take hereunder, the Escrow Agent shall thereupon have the
right (i) to refrain from complying with any claims or demands asserted on it
as the Escrow Agent or (ii) to refuse to take any other action hereunder, so
long as such disagreement continues or exists, and in either such event, the
Escrow Agent shall not be or become liable in any way to any person for the
Escrow Agent's failure to act, and the Escrow Agent shall be entitled to
continue to refrain from acting until (x) the rights of all parties shall have
been fully and finally adjudicated by a court of competent jurisdiction or (y)
all differences shall have been adjusted and all doubts resolved by agreement
among all of the interested persons, and the Escrow Agent shall have been
notified thereof by a writing signed by all such persons.  The rights of the
Escrow Agent under this subsection (g) are cumulative of all other rights which
it may have by law or otherwise.

                 (h)      In the event the Escrow Agent becomes involved in
litigation in connection with its duties under this Agreement, the Shareholders
and Quintiles shall indemnify and save the Escrow Agent harmless from all
losses, costs, damages, expenses and attorneys' fees, other than those suffered
or incurred by the Escrow Agent as a result of its own gross negligence or
willful misconduct.  [The Shareholders and Quintiles shall be jointly and
severally liable to the Escrow Agent for the obligations under this subsection
(h); provided however that as between Quintiles and the Shareholders, the
prevailing party in any such litigation shall be entitled to collect from the
non-prevailing party all amounts that the prevailing party has paid to the
Escrow Agent pursuant to this subsection (h) in connection therewith.  In the
event Quintiles is the prevailing party in any such litigation, Quintiles may
treat any amount owed by the Shareholders hereunder as an immediate liquidated
claim against the Escrow Shares pursuant to Section 4.2 above.]

         5.2.    Copies of Certifications, Notices and Other Documentation.
Promptly after receipt by the Escrow Agent from any Shareholder or Quintiles of
any written certificate, notice, request, waiver, consent, receipt or other
document, the Escrow Agent shall furnish a copy of any of such items to the
Shareholders or Quintiles, as the case may be.  Upon receipt by the Escrow
Agent of the Escrow Shares to be held in escrow pursuant to this Agreement, the
Escrow Agent shall deliver a written receipt therefor to Quintiles and the
Shareholders.

         5.3.    Compensation.  The Escrow Agent shall receive a fee of $_____
per year (the "Fee") for its services hereunder.  The first year's fee shall be
payable upon the execution of this Agreement and such fee shall not be subject
to proration in the event that the escrow arrangement terminates before the end
of a year.  Quintiles shall be responsible for payment of the Fee.  The Escrow
Agent shall also be entitled to reimbursement for all reasonable expenses,
disbursements and advances incurred or made by the Escrow Agent in accordance
with any of the provisions of this Agreement (including the reasonable
compensation and the expenses and disbursements of its counsel and of all
persons not regularly in its employ), exclusive of any such expense,
disbursement or advance that may arise from its own gross negligence or willful
misconduct.  [All





                                       7
<PAGE>   78

such reimbursement of the Escrow Agent's expenses, disbursements and advances
under the provisions of this Section 5.3 shall be paid by the Shareholders, who
shall be jointly and severally liable therefor.  Quintiles shall have the
option at any time to pay any compensation and reimbursement due to the Escrow
Agent in satisfaction of the Shareholders' obligations hereunder, and upon any
such payment, Quintiles may treat the amount of such payment as an immediate
liquidated claim against the Escrow Shares pursuant to Section 4.2 above.]

         5.4.    Successor Escrow Agent.  The Escrow Agent or any successor to
it hereafter appointed may at any time resign by giving notice in writing to
the Shareholders and Quintiles, and the Escrow Agent shall be discharged from
its duties hereunder upon the appointment of a successor Escrow Agent as
hereinafter provided, or upon the expiration of thirty (30) days after such
notice is given.  In the event of any such resignation, a successor Escrow
Agent shall be appointed by written consent of a majority in interest of the
Shareholders and Quintiles.  Any successor Escrow Agent shall deliver to the
Shareholders and Quintiles a written instrument accepting the appointment
hereunder, and thereupon it shall succeed to all the rights and duties of the
Escrow Agent hereunder and shall be entitled to receive all assets then held by
the predecessor Escrow Agent hereunder.


                                   ARTICLE VI
                                  ARBITRATION

         6.1.    Resolution of Disputed Claims.  Any unresolved dispute under
this Agreement with respect to any matter that is the subject of an asserted
claim against the Escrow Shares shall be submitted to and settled by binding
arbitration in accordance with the Commercial Rules, existing at the date
thereof, of the American Arbitration Association.  The dispute shall be
submitted by any Shareholders, subject to Section 7.8 hereof, or Quintiles to
one arbitrator agreed to by seventy-five percent (75%) in interest of the
Shareholders and Quintiles or, if such Shareholders and Quintiles cannot agree
on one arbitrator, by three arbitrators selected in accordance with said Rules,
and shall be heard in New York, New York.  Each arbitrator must be experienced
in the subject matter in dispute.  The costs and expenses of the arbitration
(including without limitation attorneys' fees) shall be paid by the
non-prevailing party in such arbitration.

         7.2     Waiver of Consent.  No failure or delay on the part of any
party hereto in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power.  The rights and remedies of the parties hereunder are
cumulative and not exclusive of any rights or remedies which they would
otherwise have.  No modification or waiver of any provision of this Agreement,
nor consent to any departure by any party therefrom, shall in any event be
effective unless the same shall be in writing, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice to or demand on any party in any case shall entitle such
party to any other or further notice or demand in similar or other
circumstances.

SECTION 2.  REGISTRATION RIGHTS.

                  2.1      INITIAL SECONDARY OFFERING.

                  (a) Quintiles shall prepare and file with the Commission a
Registration Statement for an offering (the "Initial Secondary Offering") by the
Holders of an aggregate of at least 2.7 million shares of its Common Stock and
shall use its best efforts to cause such Registration Statement to be declared
effective as soon as practicable after the Pooling Publication Date. As part of
the Initial Secondary Offering, the Company may issue and sell up to 1 million
shares of its authorized but unissued Common Stock, and Existing Holders may
sell up to 300,000 shares of Common Stock. If, prior to the completion of the
Initial Secondary Offering, any Holder or Holders sell Registrable Securities,
the amount of Registrable Securities includible in the Initial Secondary
Offering shall be reduced by the amount of such sales and the requirements of
the Initial Secondary Offering shall be deemed satisfied if such lesser amount
is sold pursuant to the Initial Secondary Offering. The Managing Underwriter for
the Initial Secondary Offering will be selected jointly by Quintiles and the
Required Holders (the "Initial Managing Underwriter").

                  (b) The number of shares of Common Stock to be offered and
sold by the Holders in the Initial Secondary Offering shall be pro rata to their
respective shareholdings. In the event that any Holders elect not to include in
the Initial Secondary Offering shares of Common Stock which they would otherwise
be entitled to include pursuant to the preceding sentence, or Existing Holders
or Quintiles elect not to include in the Initial Secondary Offering

                                       -5-



<PAGE>   95



shares of Common Stock which they would otherwise be entitled to include
pursuant to Section 2.1(a) hereof, the number of shares not offered and sold by
any such Holders or Existing Holders or Quintiles may be offered and sold by the
Holders who so elect pro rata to their respective shareholdings. If the Initial
Managing Underwriter for such offering shall advise Quintiles in writing that
the number of shares of Common Stock contemplated by Section 2.1(a) exceeds the
maximum number which such Initial Managing Underwriter believes in good faith to
be appropriate based on market conditions and other factors, including pricing,
the identity of Holders and Existing Holders selling shares of Common Stock and
the proportion of such shares being sold by Quintiles, Existing Holders and the
Holders, respectively, the number of shares of Common Stock shall be reduced
among Quintiles, the several Holders and the Existing Holders such that, of the
total number of shares of Common Stock offered and sold in the Initial Secondary
Offering (without giving effect to the exercise of any overallotment option),
67.5% shall be offered and sold by the Holders, 25.0% shall be offered and sold
by Quintiles and 7.5% shall be offered and sold by the Existing Holders.

                  (c) In the event that in connection with the Initial Secondary
Offering, an overallotment option is to be granted to the underwriters, shares
of Common Stock to be sold pursuant to such option will be sold only by the
Holders pro rata to their respective shareholdings. In the event that any
Holders elect not to include in the Initial Secondary Offering shares of Common
Stock which they would otherwise be entitled to include pursuant to the
preceding sentence, the number of shares not offered and sold by any such
Holders may be offered and sold by the Holders who so elect pro rata to their
respective shareholdings.

                  (d) Quintiles represents to the Holders that it has been
advised by the financial advisors advising it on the Exchange that an offering
of at least 4 million shares of Common Stock to be sold by Quintiles, Existing
Holders and the Holders in the proportions contemplated hereby is feasible based
on the assumption that the Exchange is completed and market conditions existing
on the date of the Share Exchange Agreement do not deteriorate significantly. If
the size of the Initial Secondary Offering may, in the view of the Initial
Managing Underwriter, Quintiles and the Holders, be increased to a level in
excess of 4 million shares of Common Stock, any shares of Common Stock to be
sold in excess of 4 million shall be sold only by the Holders pro rata to their
respective shareholdings.

                  (e) Notwithstanding the foregoing, in the event that the
Maximum Number (as defined below) of shares of Common Stock to be sold in the
Initial Secondary Offering is less than 4 million but in excess of 1.75 million
shares, the number of shares to be sold in such a reduced offering by each of
Quintiles, the Holders and the Existing Holders, respectively, shall be in such
ratio as indicated in Annex B attached hereto.

                  2.2 SHELF REGISTRATION. (a) INITIAL SHELF REGISTRATION.
Quintiles shall prepare and file with the Commission no later than 90 days
following the settlement of the Initial Secondary Offering, or, if such
settlement shall not have occurred on or prior to March 31, 1997, no later than
March 31, 1997, one or more Registration Statements under the Regulations

                                       -6-



<PAGE>   96



covering at least 5 million Registrable Securities for offerings to be made by
Holders from time to time in the aggregate amount of no more than 500,000
Registrable Securities in any 90 day period (any or all such Registration
Statements being hereinafter referred to as the "Initial Shelf Registration");
provided, however, that the volume of Registrable Securities that may be sold
pursuant to the plan of distribution described in any Registration Statement for
the Initial Shelf Registration may be increased from time to time by Quintiles
after consultation with Goldman, Sachs & Co. upon reasonable prior notice to the
Holders. The Initial Shelf and any Subsequent Shelf Registrations shall be
non-underwritten. The Initial Shelf Registration shall be on Form S-3 or another
appropriate form permitting registration of such Registrable Securities for
resale by such Holders in the manner or manners designated by them subject to
the provisions hereof. Quintiles shall use its best efforts to cause the Initial
Shelf Registration to be declared effective under the Securities Act not later
than (i) the 121st calendar day subsequent to the settlement of the Initial
Secondary Offering or (ii) if such settlement shall not have occurred on or
prior to March 31, 1997, on or as soon as practicable after March 31, 1997 and
to keep the Initial Shelf Registration continuously effective under the
Securities Act until such time as the earlier of (i) 4 million of the
Registrable Securities covered by the Initial Shelf Registration have been sold
in the manner set forth and as contemplated in the Initial Shelf Registration,
(ii) a Subsequent Shelf Registration (as defined herein) covering all of the
Registrable Securities covered by the Initial Shelf Registration and not
previously sold has been declared effective under the Securities Act, (iii)
registration of the Registrable Securities is no longer required under the
Securities Act and the Holder may sell all remaining Registrable Securities in
the open market in amounts that equal or exceed the amount that can be sold
under this clause pursuant to the volume and other limitations of Rule 144 or
otherwise (giving effect to the 90-day period in both cases), (iv) the covered
securities cease to be Registrable Securities or (v) three years have elapsed
from the date on which the Initial Shelf Registration was first declared
effective (the "Shelf Effectiveness Period").

                  (b) SUBSEQUENT SHELF REGISTRATIONS. If the Initial Shelf
Registration or any Subsequent Shelf Registration (as defined below) ceases to
be effective for any reason at any time during the Shelf Effectiveness Period
(other than because of the sale of all of the securities registered thereunder),
Quintiles shall use its best efforts to obtain the prompt withdrawal of any
order suspending the effectiveness thereof, and in any event shall within 30
days of such cessation of effectiveness (i) amend the Shelf Registration in a
manner reasonably expected to obtain the withdrawal of the order suspending the
effectiveness thereof, or (ii) file an additional Registration Statement
covering all of the Registrable Securities covered by the Initial Shelf
Registration and not previously sold (a "Subsequent Shelf Registration") for an
offering to be made by the holders on a delayed or continuous basis under the
Regulations. If a Subsequent Shelf Registration is filed, Quintiles shall use
its best efforts to cause the Subsequent Shelf Registration to be declared
effective as soon as practicable after such filing and to keep such Registration
Statement continuously effective for the remaining portion of the Shelf
Effectiveness Period. As used herein, the term "Shelf Registration" means the
Initial Shelf Registration and any Subsequent Shelf Registration.


                                       -7-



<PAGE>   97



                  (c) SUPPLEMENTS AND AMENDMENTS. Quintiles shall supplement and
amend the Shelf Registration if required by the Regulations applicable to the
registration form used for such Shelf Registration, if required by the
Securities Act or the Regulations, or if reasonably requested by the Holders of
a majority in interest of the Registrable Securities covered by such
Registration Statement.

                  (d) BLACKOUT PERIOD. Notwithstanding the other provisions of
this Section 2.2, Quintiles shall have the right to delay the filing of any
Shelf Registration otherwise required to be prepared and filed by Quintiles
pursuant to this Section 2.2, or to suspend the use of any Shelf Registration,
for a period not in excess of 90 days (a "Shelf Blackout Period") if Quintiles
determines that the registration and distribution of the Registrable Securities
to be covered by such Shelf Registration would materially interfere with any
pending financing, acquisition or other transaction involving Quintiles or would
require disclosure of information which is in its best interest not to publicly
disclose provided, that, the Blackout Period shall earlier terminate upon the
completion or abandonment of the relevant financing, acquisition or other
transaction or upon public disclosure by Quintiles or public admission by
Quintiles of such material nonpublic information or such time as such material
nonpublic information shall be publicly disclosed; and provided, further, that
Quintiles shall furnish to the Holders a certificate of an executive officer of
Quintiles to the effect that an event permitting a Blackout Period has occurred
(and no other reason need be given); provided, further, that for each Shelf
Blackout Period, the Holders' right to have a minimum number of Registrable
Securities sold pursuant to Section 2.2 shall be extended by an equal period
beyond the date such right would otherwise have terminated. Quintiles will
promptly give the Holders written notice of such determination and an
approximation of the period of the anticipated delay; provided, however, that
the aggregate number of days included in all Shelf Blackout Periods during any
consecutive 12 months shall not exceed 180 days. Each Holder agrees to cease all
disposition efforts under such Registration Statement with respect to
Registrable Securities held by such Holder immediately upon receipt of notice of
the beginning of any Shelf Blackout Period. Quintiles shall provide written
notice to the Holders of the end of each Shelf Blackout Period.

                  (e) MANNER OF SALE. The Holders agree that all sales of
Registrable Securities covered by a Shelf Registration shall be made through one
of the top three market-makers (in terms of NASDAQ-trading volume) in Quintiles
Common Stock subject to such market-makers offering best market terms.

                  2.3 DEMAND RIGHTS. (a) Subject to Section 2.3(b) below, at any
time, and from time to time, on or after the date on which Holders are first
permitted to sell shares following the Initial Secondary Offering any Holder or
group of Holders who hold and propose to sell Registrable Securities with an
aggregate value of at least $50 million (herein, individually or collectively,
as the case may be, a "Demanding Holder"), shall have the right to require

Offering of all or part of such Demanding Holder's Registrable Securities, up to
a maximum of 2.7 million shares in the aggregate, reduced by the number of

Holders in the Initial Secondary Offering or pursuant to any prior Demand
Request, by delivering written notice thereof to Quintiles specifying the number
of Registrable Securities to be included in such registration and the intended
method of distribution thereof (the "Demand Request"). Quintiles shall, within
10 days after receipt, give written notice by facsimile transmission (the
"Notice of Demand Request") of such Demand Request to all Holders of any
Registrable Securities. Thereupon Quintiles shall prepare and file with the
Commission as promptly as practicable following the receipt of the Notice of
Demand Request, and in any event within 30 days thereafter, a Registration
Statement covering, and shall use its best efforts to effect the registration
under the Securities Act of, (i) the Registrable Securities included in the
Demand Request, for disposition in accordance with the intended method of
disposition stated in the Demand Request and (ii) all other Registrable
Securities as to which the Holders thereof that have received a Notice of Demand
Request and shall have made a written request (a "Joining Request") to Quintiles
for registration thereof within ten days after the transmittal of such Notice of
Demand Request, in each case subject to the 2.7 million (or lesser) share
maximum referred to in the preceding sentence, all to the extent necessary to
permit the sale or other disposition by such Holders (each, a "Seller" and,
collectively, the "Sellers") of such Registrable Securities.

                  (b) Quintiles's obligations pursuant to Section 2.3(a) above
are subject to the following limitations and conditions: (i) Quintiles shall not
be obligated to fulfill the requirements or file the Registration Statement
referred to therein (A) during any period of time (not to exceed sixty (60) days
in the aggregate with respect to each request) when Quintiles has determined to
proceed with a Public Offering (whether for its own account or that of any
Holder pursuant to any previously received Demand Request and related Joining
Request) and, in the judgment of the managing underwriter thereof, the
fulfillment of such requirements or such filing would have an adverse effect on
the material terms of such offering, (B) during any period of time (not to
exceed ninety (90) days with respect to each request) when Quintiles is in
possession of material information that Quintiles (x) has determined, after
advice of Quintiles's lead US securities counsel, would be required to be
disclosed in an offering registered under the Securities Act and (y) reasonably
deems is in Quintiles's best interests not to publicly disclose, or (C) during
the 90-day period following the effectiveness of any previous Registration
Statement (the periods of time referred to in subclauses (A), (B) and (C) hereof
being hereinafter referred to as "Blackout Periods"); provided, that the
aggregate period of time during which Quintiles shall be relieved from its
obligation to file such a Registration Statement pursuant to this clause (i)
shall in no event exceed ninety (90) consecutive days with respect to each
request; provided, further, that, in the case of a Blackout Period pursuant to
sub-clause (i)(A) above, the Blackout Period shall earlier terminate upon the
completion or abandonment of the relevant securities offering; provided,
further, that in the case of a Blackout Period pursuant to sub-clause (i)(B)
above, the Blackout Period shall earlier terminate upon public disclosure by
Quintiles or public admission by Quintiles of such material nonpublic
information or such time as such material nonpublic information shall be
publicly disclosed without breach of the last sentence of this subsection (b);
and provided, further, that in the case of a Blackout Period pursuant to
subclauses (i)(A), (B) or (C) above, Quintiles shall furnish to the Security
Holders a certificate of

                                       -9-



<PAGE>   99



an executive officer of Quintiles to the effect that an event permitting a
Blackout Period has occurred and is continuing (and no other reason need be
given); provided, further, that Quintiles shall not be entitled to exercise its
rights under sub-clause (i)(B) more than three (3) times in any twenty-four (24)
month period, and under sub-clause (i)(C) more than one (1) time in any
nine-month period; and provided, further, that if prior to the expiration of any
Blackout Period the Demanding Holders withdraw their Demand Request, such
request shall not be considered a Demand Request for purposes of this Section
2.3(b) and such Demand Request and any Joining Request related thereto shall be
of no further effect; (ii) Quintiles shall not be required to maintain the
effectiveness of a Registration Statement filed pursuant to Section 2.3(a) for a
period in excess of thirty (30) days; (iii) the minimum aggregate offering price
of any such Public Offering, as estimated in good faith by the managing
underwriter thereof immediately prior to the time the Registration Statement
with respect to any such Public Offering becomes effective, shall be at least
$50 million; (iv) the number of shares of Common Stock to be sold in any such
Public Offering shall not exceed the maximum number which the managing
underwriter thereof considers in good faith to be appropriate based on market
conditions and other relevant factors, including pricing, the identity of the
Holders and Existing Holders selling shares of Common Stock and the proportion
of shares of Common Stock being sold by Quintiles, by the Holders and by the
Existing Holders (the "Maximum Number"); and (v) Quintiles shall not during the
Demand Period (as defined below) be obligated to effect more than one Demand
Registration in any six-month period.

                  (c) Subject to Section 2.5, Quintiles may elect to include in
any Registration Statement filed pursuant to this Section 2.3 any authorized but
unissued shares of Common Stock; provided, that such inclusion shall be
permitted only to the extent that it is pursuant to and subject to the terms of
any underwriting agreement or arrangements entered into by the Demanding Holders
whose Registrable Securities are also included therein.

                  (d) A request by a Holder or Holders that Quintiles file a
Registration Statement shall not be considered a Demand Request if the
Registration Statement relating thereto does not become effective, through no
fault of the Holders.

                  2.4. "PIGGY-BACK" RIGHTS. If at any time within three years
from the settlement of the Initial Secondary Offering, Quintiles proposes to
register any authorized but unissued shares of Common Stock under the Securities
Act on a registration statement on Form S-1, Form S-2 or Form S-3 (or an
equivalent general registration form then in effect) for purposes of a Public
Offering by Quintiles of such shares, Quintiles shall give written notice of
such proposal at least twenty (20) days before the anticipated filing date,
which notice shall include the intended method of distribution of such shares,
to each of the Holders who hold Registrable Securities. Such notice shall
specify at a minimum the number of shares of Common Stock proposed to be
registered, the proposed filing date of such registration statement, any
proposed means of distribution of such shares and the proposed managing
underwriter, if any. Subject to Section 2.5, upon the written request of any
such Holder, given within ten (10) days after the receipt of any such written
notice by facsimile confirmed by mail (which request shall specify

                                      -10-



<PAGE>   100



the Registrable Securities intended to be disposed of by such Holder), Quintiles
will use its best efforts to include in the registration statement with respect
to such Public Offering the number of the Registrable Securities referred to in
such Holder's request; provided, that, any participation in such Public Offering
by such Holders shall be on substantially the same terms as Quintiles's
participation therein; and provided, further, that the number of Registrable
Securities to be included in any such Public Offering shall not exceed the
Maximum Number. Any such Holder shall have the right to withdraw a request to
include Registrable Securities in any Public Offering pursuant to this Section
2.4 by giving written notice to Quintiles of its election to withdraw such
request at least five (5) days prior to the proposed effective date of such
registration statement.

                  2.5. ALLOCATION OF SECURITIES INCLUDED IN A PUBLIC OFFERING.
If the managing underwriter for any Public Offering to be effected pursuant to
Section 2.3 or Section 2.4 of this Agreement shall advise Quintiles and the
Sellers in writing that the number of shares of Common Stock sought to be
included in such Public Offering (including those sought to be offered by
Quintiles, those sought to be offered by Sellers and those sought to be offered
by Existing Holders) is more than the Maximum Number, the shares of Common Stock
to be included in such Public Offering shall be allocated pursuant to the
following procedures:

                  (a) until such time as the Holders have sold in the aggregate
         at least 2.7 million shares of Common Stock (whether through the
         Initial Secondary Offering or otherwise) (the "Demand Period"),
         Registrable Securities to be sold pursuant to any Registration
         Statement (whether as a result of a Demand Request or otherwise, but
         not including any Shelf Registration Statement) shall be allocated
         among the Holders and Quintiles and Existing Holders such that, of the
         total number of shares sold pursuant to such Registration Statement,
         67.5% shall be sold by the Holders, 25% shall be sold by the Company
         and 7.5% shall be sold by Existing Holders; provided that (i) to the
         extent that Existing Holders or Quintiles elect not to sell pursuant to
         such Registration Statement shares of Common Stock which they would
         otherwise be entitled to sell pursuant to the preceding clause, the
         number of shares not sold by such Existing Holders or Quintiles may be
         sold by the Holders who so elect pro rata to their respective
         shareholdings, and (ii) in the event that in connection with any
         underwritten offering pursuant to any such Registration Statement an
         overallotment option is granted to the underwriters, shares of Common
         Stock to be sold pursuant to such option shall be sold by the Holders
         pro rata to their respective shareholdings;

                  (b) if, following the end of the Demand Period, such
         registration or Public Offering is pursuant to Section 2.4 of this
         Agreement, (x) first, securities sought to be included at the request
         of Quintiles shall be included, and (y) second, if the number of
         securities to be registered exceeds the Maximum Number, the amount of
         Registrable Securities proposed to be offered by Holders shall be
         reduced as agreed among such Holders, to the extent necessary to reduce
         the total amount of securities to be included

                                      -11-



<PAGE>   101



         in such offering to the Maximum Number; provided that shares to be sold
         by the Holders are not reduced to less than 20% of all shares to be
         sold in such Public Offering.

                  2.6. REQUIREMENTS WITH RESPECT TO REGISTRATION. Subject to
Section 4 and to Quintiles's rights with respect to Blackout Periods and Shelf
Blackout Periods, if and whenever Quintiles is required by the provisions hereof
to use its best efforts to register any Registrable Securities under the
Securities Act, Quintiles shall:

                  (a) As promptly as practicable (and in the case of a Demand
         Request, in no event more than 30 days following such Demand Request)

         prospectus or any amendments or supplements thereto, Quintiles shall
         furnish to and afford the Holders of the Registrable Securities covered
         by such Registration Statement, and the managing underwriters, if any,
         a reasonable opportunity to review and comment on copies of all such
         documents (including copies of any documents to be incorporated by
         reference therein and all exhibits thereto) proposed to be filed.

                  (b) As promptly as practicable, prepare and file with the
         Commission such amendments and supplements to such Registration
         Statement and the prospectus used in connection therewith as may be
         necessary to keep such Registration Statement current and effective and
         to comply with the provisions of the Securities Act, and the
         Regulations, with respect to the sale or disposition of such
         Registrable Securities (the "Effectiveness Period"). In the event of an
         underwritten offering, Quintiles shall select the managing
         underwriter(s), except as provided in Section 2.1(a).

                  (c) Promptly notify each Seller of any Registrable Securities
         covered by such Registration Statement (A) when the Registration
         Statement or any related prospectus or any amendment or supplement has

         post-effective amendment, when the same has become effective, (B) of
         any request by the Commission for amendments or supplements to the
         Registration Statement or the related prospectus or for additional
         information, (C) of any order issued or threatened by the Commission
         suspending the effectiveness of such Registration Statement, preventing
         or suspending the use of a prospectus or suspending the qualification
         (or exemption from qualification) of any of the Registrable Securities
         for sales in any jurisdiction Quintiles shall use its best efforts to
         prevent the issuance of any such order and, if any such order is
         issued, shall use its best efforts to obtain the withdrawal of any such
         order at the earliest possible moment or (D) of the receipt by
         Quintiles of any notification with respect to the suspension of the
         qualification of the Registrable Securities for sale in any
         jurisdiction or the initiation of any proceedings for such purpose.

                  (d) Immediately upon becoming aware thereof, notify each
         Seller and underwriter of such Registrable Securities, at any time when
         a prospectus relating thereto is required to be delivered under the
         Securities Act, of the occurrence of an event requiring the preparation
         of a supplement or amendment to such prospectus so that, as thereafter
         delivered to the purchasers of such Registrable Securities, such
         prospectus will not contain an untrue statement of a material fact or
         omit to state any 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 and promptly
         make available to each Seller and underwriter any such supplement or
         amendment, unless suspension of the use of such prospectus otherwise is

         Blackout Periods, in which case no supplement or amendment need be
         furnished. The Holders may not make use of any Registration Statement
         while its use is suspended.

         managing underwriter thereof shall reasonably request, and do any and
         all other acts and things that may be reasonably necessary to enable
         each participating Seller or underwriter to consummate the disposition
         of the Registrable Securities in such jurisdictions; provided, however,

         as a foreign corporation in any jurisdiction where it is not so
         qualified; or to execute or file any general consent to service of
         process under the laws of any jurisdiction.

         inspection by any Seller of such Registrable Securities, any
         underwriter participating in any disposition pursuant to such

         professional retained by any such Seller or underwriter (collectively,
         the "Inspectors"), all financial and other records, pertinent corporate
         documents and properties of Quintiles (collectively, the "Records") as

         investigation for purposes of Section 11(a) of the Securities Act and
         cause Quintiles's officers, directors and employees to supply all

         qualified for trading on any other stock exchange or quotation service
         on which Quintiles's outstanding shares of Common Stock are listed or
         qualified for trading.

                  (h) Furnish to each Seller and each underwriter of the
         Registrable Securities covered by such Registration Statement such
         number of copies of such Registration Statement, each amendment and

         expedite or facilitate the registration or the disposition of such
         Registrable Securities, and in such connection, (A) make such
         representations and warranties to the underwriters and the Sellers with
         respect to the business of Quintiles and its subsidiaries, and the
         Registration Statement, Prospectus and documents, if any, incorporated
         or deemed to be incorporated by reference therein, in each case, as are

         made by selling security holders, and confirm the same on the
         settlement date for the offering; (B) cause opinions of counsel to
         Quintiles (which counsel and opinions shall be reasonably satisfactory

         requested in underwritten offerings by selling security holders; (C)
         cause "cold comfort" letters and updates thereof (which letters and

         necessary, any other independent certified public accountants of any
         subsidiary of Quintiles or of any business acquired by Quintiles for
         which financial statements and financial data are, or are required to
         be, included in the Registration Statement), to be delivered to each of
         the underwriters and the Sellers of such Registrable Securities

         opinions and letters referred to above shall be done at each closing
         under such underwriting agreement, as and to the extent required
         thereunder.

                  (j) Comply with all applicable rules and regulations of the
         Commission and make generally available to security holders earning

         period (or 90 days after the end of any 12-month period if such period
         is a fiscal year) (A) commencing at the end of any fiscal quarter in
         which Registrable Securities are sold to underwriters in a Public
         Offering and (B) if not sold to underwriters in such an

         offering, commencing on the first day of the fiscal quarter of
         Quintiles after the effective date of a Registration Statement, which
         statements shall cover said 12-month periods.

                  (k) Cooperate with each Seller and the managing underwriter,
         if any, participating in the disposition of such Registrable Securities
         in connection with any filings required to be made with the National
         Association of Securities Dealers, Inc. (the "NASD").

                  (l) Use its best efforts to take all other steps reasonably
         necessary to effect the registration, offering and sale of the
         Registrable Securities covered by a Registration Statement contemplated
         hereby and enter into any other customary agreements and take such
         other actions, including participation in "roadshows", as are
         reasonably required in order to expedite or facilitate the disposition
         of such Registrable Securities.

                  (m) Until there are no Registrable Securities outstanding or,
         if earlier, March 31, 1999, at the reasonable request of the Holders,
         hold periodic meetings with representatives of the Holders to report on
         the market for Quintiles's shares and opportunities for such Holders to
         effect sales of Registrable Securities.

                  (n) With respect to any Registration Statement under Section 2
         hereof, the Company may require each Holder disposing of Registrable
         Securities covered by such Registration Statement to furnish such
         information regarding the Holder and such Holder's intended disposition
         of Registrable Securities as the Company may from time to time
         reasonably request (with reasonable prior notice) in writing. If any
         such information with respect to the Holder is not furnished within a
         reasonable period of time after receipt of such request, the Company
         may exclude such Holder's Registrable Securities from such Registration
         Statement.

period beginning 30 days prior to, and ending 120 days after, the closing date

relations or other consultants retained by Quintiles in connection with any
roadshow (including travel and other arrangements for any investor presentations
or meetings); (ix) all out-of-pocket expenses of Quintiles (including, without
limitation, expenses incurred by officers and employees of Quintiles performing
legal or accounting duties or participating in "roadshow" presentations), and
(x) the fees and expenses incurred in connection with the quotation or listing
of shares of Common Stock on any securities exchange or automated securities
quotation system ((i) through (x) above collectively, "Registration Expenses").

                  (b) Each Seller shall pay all underwriting discounts and
commissions or broker's commissions incurred in connection with the sale or
other disposition of Registrable Securities for or on behalf of such Seller's
account and any fees and expenses of legal counsel and other advisors separately
engaged by them for such Seller.

SECTION 5.  REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

                  (a) Quintiles Representations, Warranties and Agreements.
Quintiles represents and warrants to, and agrees with, each Holder that:

                           (i) Quintiles has all requisite corporate power and
         authority to execute, deliver, and perform this Agreement. This
         Agreement has been duly authorized, executed, and delivered by
         Quintiles. No consent, authorization, approval, order, license,
         certificate, or permit of or from, or declaration or filing with, any
         United States federal, state, local, or other governmental authority or
         any court or other tribunal is required by Quintiles for the execution,
         delivery or performance of this Agreement by Quintiles (except filings
         under the Securities Act which will be made and any consents under Blue
         Sky or state securities laws which will be obtained).

                           (ii) Quintiles shall not enter into any transaction
         involving the issuance or transfer by any other Person of Other
         Securities to any Holder, or any merger or consolidation in which it is
         not the surviving Person, or any sale, lease or other transfer of all
         or substantially all the assets of Quintiles, unless effective
         provision is made for the assumption by such other Person, jointly and
         severally with Quintiles if Quintiles shall remain in existence, of all
         of the obligations of Quintiles hereunder, and in the case of any such
         issuance or transfer, the registration of such Other Securities on the
         same basis as the registration of the other Registrable Securities
         hereunder.

                           (iii) The execution and delivery of this Agreement by
         Quintiles do not, and the consummation of the transactions contemplated
         hereby will not, violate, conflict with, or result in a breach of any
         provision of, or constitute a default (with or without notice or lapse
         of time or both) under, or result in the termination of, or accelerate
         the performance required by, or result in a right of termination,
         cancellation, or acceleration of any obligation or the loss of a
         material benefit under, or result in the creation of any lien, security
         interest, charge or encumbrance upon any of the properties or assets
         (any such violation, conflict, breach, default, right of termination,
         cancellation or acceleration, loss or creation, a "Violation") of
         Quintiles or any of its subsidiaries pursuant to any provisions of (i)
         the articles of incorporation, by-laws or similar governing documents
         of Quintiles or any of its subsidiaries, (ii) any statute, law,
         ordinance, rule, regulation, judgment, decree, order, injunction, writ,
         permit or license of any governmental authority applicable to Quintiles
         or any of its subsidiaries or any of their respective properties or
         assets or (iii) any note, bond, mortgage, indenture, deed of trust,
         license, franchise, permit, concession, contract, lease or other
         instrument, obligation or agreement of any kind to which Quintiles or
         any of its subsidiaries is a party or by which it or any of its
         properties or assets may be bound or affected.

                           (iv) Quintiles covenants that it will file any
         reports required to be filed by it under the Securities Act and the
         Exchange Act, will make available "adequate

                                      -17-



<PAGE>   107
         current public information concerning Quintiles within the meaning of
         paragraph (c) of Rule 144" and that it will take such further action as
         any Holder may reasonably request, all to the extent required from time
         to time to enable Holders to sell Registrable Securities without
         registration under the Securities Act pursuant to the exemptions
         provided by Rule 144. Upon the request of any Holder, Quintiles will
         deliver to such Holder a written statement as to whether it has
         complied with such requirements.

                          (v) Quintiles covenants that it will not conduct any
         offering of equity (or equity-linked) securities, whether registered
         under the Securities Act or otherwise, from and after the date of the
         Closing until the earlier of (A) the closing of the Initial Secondary
         Offering and (B) March 31, 1997 (the "Priority Period") (excluding, for
         the avoidance of doubt, the Initial Secondary Offering itself), other
         than securities issued (i) in connection with Quintiles's acquisition
         of BRI, (ii) pursuant to any employee benefit plans, employee stock
         option plans and stock purchase plans of Quintiles as in effect as of
         the date of this Agreement, and (iii) shares of Common Stock issued
         upon conversion of the convertible debentures of Quintiles outstanding
         as of the date of this Agreement.

                 (b)      Holder Representations, Warranties and Agreements. 
         Each Holder represents and warrants to, and agrees with, Quintiles,
         that:

                          (i) Such Holder, if not a natural person, is duly
         organized, validly existing, and in good standing under the laws of its
         jurisdiction of organization. Such Holder has all requisite power and
         authority to execute, deliver, and perform this Agreement. This
         Agreement has been duly authorized by such Holder, if not a natural
         person, and has been duly executed and delivered by such Holder.

                          (ii) Neither such Holder nor any such Holder's
         Affiliates will take, directly or indirectly, during the term of this
         Agreement, any action designed to stabilize (except as may be permitted
         by applicable law) or manipulate the price of any security of
         Quintiles.

                          (iii) Such Holder shall promptly furnish to Quintiles
         upon Quintiles's request any and all information as may be required by,
         or as may be necessary or advisable to comply with the provisions of,
         the Securities Act, the Regulations, the Exchange Act, and the rules
         and regulations of the Commission thereunder in connections with the
         preparation and filing of any Registration Statement pursuant hereto,
         or any amendment or supplement thereto, or any Preliminary Prospectus
         or Prospectus included therein.

SECTION 6.   SURVIVAL OF REPRESENTATIONS AND AGREEMENTS.

             All representations, warranties, covenants and agreements
contained in this Agreement shall be deemed to be representations, warranties,
covenants and agreements at the effective date of each Registration Statement
contemplated by this Agreement, and such representations, warranties, covenants
and agreements, shall remain operative and in full force and effect regardless
of any investigation made by or on behalf of Quintiles, any Holder, or any other
Person and shall survive termination of this Agreement.


SECTION 7.   INDEMNIFICATION

             (a) Indemnification by Quintiles. Quintiles shall, without
limitation as to time, indemnify and hold harmless, to the fullest extent
permitted by law, each holder of Registrable Securities, and any underwriter
participating in the distribution, their respective officers, directors and
agents and employees of each of them, each Person who controls each such holder
or any such underwriter (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act) and the officers, directors, agents and
employees of each such controlling person (individually, an "Indemnified
Person") from and against any and all losses, claims, damages, liabilities,
costs (including, without limitation, costs of investigating, preparing to
defend, defending and appearing as a third-party witness and attorney's fees and
disbursements) and expenses, including any amounts paid in respect of any
settlements (collectively, "Losses"), joint or several, without duplication, as
incurred, arising out of or based upon any untrue or alleged untrue statement of
a material fact contained in any Registration Statement, Prospectus or form of
prospectus, or in any amendment or supplements thereto or in any Preliminary
Prospectus, or arising out of or based upon, in the case of the Registration
Statement or any amendments thereto, any omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and, in the case of the Prospectus or form of
prospectus, or in any amendments or supplements thereto, or in any Preliminary
Prospectus, any omission or alleged omission of 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 except, in either case,
(i) to the extent, but only to the extent, that such untrue or alleged untrue
statement or omission or alleged omission has been made therein in reliance upon
and in conformity with information furnished in writing to Quintiles by such
Indemnified Person expressly for use therein and (ii) if the person asserting
any such Losses who purchased the Registrable Securities which are the subject
thereof did not receive a copy of an amended Preliminary Prospectus or the final
Prospectus (or the final Prospectus as amended or supplemented) at or prior to
the written confirmation of the sale of such Registrable Securities to such
person 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 final Prospectus (or the
final Prospectus as amended and supplemented).


                                      -19-
<PAGE>   109



                  (b) Indemnification by Holder of Registrable Securities. In
connection with any Registration Statement in which a Holder of Registrable
Securities is participating, such Holder of Registrable Securities shall furnish
to Quintiles in writing such information as Quintiles reasonably requests for
use in connection with any Registration Statement or Prospectus, and shall
severally, without limitation as to time, indemnify and hold harmless, to the
fullest extent permitted by law, Quintiles, any underwriter participating in the
distribution and their respective directors, officers, agents and employees,
each Person who controls Quintiles or any such underwriter (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling person, from and
against any and all Losses, as incurred, arising out of or based upon (i) any
untrue or alleged untrue statement of a material fact contained in any
Registration Statement, Prospectus, or form of prospectus, or in any amendment
or supplement thereto or in any Preliminary Prospectus, or arising out of or
based upon, in the case of the Registration Statement or any amendments thereto,
any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading, and, in the
case of the Prospectus, or form of prospectus, or in any amendments or
supplements thereto, or in any Preliminary Prospectus, any omission or alleged
omission of 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, in either case, to the extent, but only to the extent,
that such untrue or alleged untrue statement or omission or alleged omission has
been made therein in reliance upon and in conformity with information furnished
in writing to Quintiles by such Holder expressly for use therein or (ii) the
failure of such participating Holder or any underwriter acting for such
participating Holder at or prior to the written confirmation of the sale of the
Registrable Securities to send or deliver a copy of an amended Preliminary
Prospectus or the final Prospectus (or the final Prospectus as amended or
supplemented) to the person asserting any such Losses who purchased the
Registrable Securities 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 final Prospectus (or the final Prospectus as amended and
supplemented). In no event shall the liability of any Seller of Registrable
Securities hereunder be, or be claimed by Quintiles to be, greater in amount
than the dollar amount of the proceeds actually received by such Seller upon the
sale of the Registrable Securities giving rise to such indemnification
obligation.

                  (c) Conduct of Indemnification Proceedings. Each Indemnified
Person shall give prompt notice to the party or parties from which such
indemnity is sought (the "indemnifying parties") of the commencement of any
action or proceeding (including any governmental investigation) (collectively
"Proceedings" and individually a "Proceeding") with respect to which such
Indemnified Person seeks indemnification or contribution pursuant hereto;
provided, however, that the failure so to notify the indemnifying parties shall
not relieve the indemnifying parties from any obligation or liability except to
the extent that the indemnifying party was otherwise unaware of such Proceeding
and the indemnifying parties shall have been materially prejudiced by such
failure. The indemnifying parties shall have the right, exercisable by giving

                                      -20-



<PAGE>   110



written notice to an indemnified party promptly after the receipt of written
notice from such indemnified party of such Proceeding, to assume, at the
indemnifying parties' expense, the defense of any such proceeding, with counsel
reasonably satisfactory to such indemnified party and shall pay as incurred the
fees and disbursements of such counsel related to such Proceeding; provided,
however, that an indemnified party or parties (if more than one such indemnified
party is named in any Proceeding) shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless: (1) the indemnifying party or parties agree
to pay such fees and expenses; or (2) the indemnifying parties fail promptly to
assume the defense of such Proceeding or fail to employ counsel reasonably
satisfactory to such indemnified party or parties; or (3) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party or parties shall
have been advised by counsel that there may be a conflict between the positions
of the indemnifying party or an affiliate of the indemnifying party and such
indemnified party or parties in conducting the defense of such action or
proceeding or that there may be legal defenses available to such indemnified
party or parties different from or in addition to those available to the
indemnifying party or such affiliate, in which case, if such indemnified party
or parties notifies the indemnifying parties in writing that it elects to employ
separate counsel at the expense of the indemnifying parties, the indemnifying
parties shall not have the right to assume the defense thereof and such counsel
shall be at the expense of the indemnifying parties, it being understood,
however, that the indemnifying parties shall not, in connection with any one
such Proceeding or separate but substantially similar or related Proceedings in
the same jurisdiction, arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (together with appropriate local counsel) at any time
for such indemnified party or parties. Whether or not such defense is assumed by
the indemnifying parties, such indemnifying parties or indemnified party or
parties will not be subject to any liability for any settlement made without its
or their consent (but such consent will not be unreasonably withheld). No
indemnifying party shall be liable for any settlement of any such action or
proceeding effected without its written consent, but if settled with its written
consent each indemnifying party jointly and severally agrees, subject to the
exception and limitations set forth above, to indemnify and hold harmless each
indemnified party from and against any loss or liability by reason of such
settlement. No indemnification provided for in Section 7(a) or Section 7(b)
shall be available to any party who shall fail to give notice as provided in
this Section 7(c) if the party to whom notice was not given was unaware of the
proceeding to which such notice would have related and was materially prejudiced
by the failure to give such notice, but the failure to give such notice shall
not relieve the indemnifying party or parties from any liability which it or
they may have to the indemnified party otherwise than on account of the
provisions of Section 7(a) or Section 7(b).

                  (d) Contribution. If the indemnification provided for in this
Section 7 is unavailable to an indemnified party or is insufficient to hold such
indemnified party harmless for any Losses in respect to which this Section 7
would otherwise apply by its terms, except by

                                      -21-



<PAGE>   111



reasons of Section 7(a)(i) or (ii) hereof or the failure of the indemnified
party to give notice as required in Section 7(c) hereof (provided that the
indemnifying party was unaware of the proceeding to which such notice would have
related and was prejudiced by the failure to give such notice), then each
applicable indemnifying party, in lieu of indemnifying such indemnified party,
shall have an obligation to contribute to the amount paid or payable by such
indemnified party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the indemnifying party, on the one
hand, and such indemnified party, on the other hand, in connection with the
actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. Where the indemnified party is an
underwriter participating in the distribution of Registrable Securities,
however, each indemnifying party, and, in addition, if the indemnifying party is
a Holder, Quintiles, shall have an obligation to contribute to the amount paid
or payable by such indemnified part as the result of such Losses in such
proportion as is appropriate to reflect not only (i) the relative fault of
Quintiles, the Holders and the underwriters in connection with the actions,
statements or omissions that resulted in such Losses, as well as any other
relevant equitable considerations, but also (ii) the relative benefits received
by the Holders on the one hand and the underwriters on the other hand from the
distribution of the Registrable Securities. The relative benefit derived by the
parties shall be determined by reference to, among other things, the fact that
Quintiles entered into this Agreement to induce the Holders to engage in the
transaction in which the Registrable Securities were acquired. The relative
benefits received by the Holders 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 any such offering (before deducting expenses) received by the Holders bear
to the total underwriting discounts or commissions received by the underwriters.
The relative fault of such indemnifying party, on the one hand, and indemnified
party, on the other hand, shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, has been taken by, or relates to information supplied by, such
indemnifying party or indemnified party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent any such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include any legal or other fees or expenses
incurred by such party in connection with any Proceeding, to the extent such
party would have been indemnified for such expenses if the indemnification
provided for in Section 7(a) or 7(b) were available to such party.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation or by any other method of allocation that does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 7(d), an indemnifying
party that is a selling Holder of Registrable Securities shall not be required
to contribute any amount in excess of the amount by which the total price at
which the Registrable Securities sold by such indemnifying party and distributed
to the public were offered to the public (net of any underwriting discounts and
commissions and expenses) exceeds the amount of any damages that such
indemnifying party has otherwise been required to pay or has paid by

                                      -22-



<PAGE>   112
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 Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

             (e) Remedies Cumulative. The indemnity, contribution and expense 
reimbursement obligations under this Section 7 shall be in addition to any 
liability each indemnifying person may otherwise have and shall remain 
operative and in full force and effect regardless of any investigation made by
or on behalf of any indemnified party.

             (f) Underwriting Agreement Controls. In the event of any conflict 
between the indemnification and contribution terms as herein set forth and as 
set forth in any underwriting agreement entered pursuant hereto, the 
underwriting agreement shall control.


SECTION 8.   UNDERWRITTEN REGISTRATION

             No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (i) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Holders of a majority of Registrable Securities
included in such offering, and (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements, custodial or escrow
agreements and other documents required under the terms of such underwriting
arrangements.


SECTION 9.   UNREGISTERED OFFERINGS

             The parties hereto hereby agree that, in the event that Quintiles 
or one or more Holders propose to make an underwritten Public Offering of 
shares of Common Stock (i) that is exempt from, or not subject to, the
registration requirements of the Securities Act pursuant to Regulation S (or any
successor or similar regulation) thereunder and (ii) with respect to which the
Holder or Holders proposing such underwritten offering request the cooperation
and participation of Quintiles or the management of Quintiles in performing due
diligence and marketing such offering to potential investors, the relevant
notice provisions of Section 2.3 or 2.4 will state that the offering is proposed
to be made on an unregistered basis pursuant to Regulation S. In that event, the
parties agree to proceed with such an offering on an unregistered basis pursuant
to Regulation S in good faith as and to the extent provided herein with respect
to a registered offering and that the provisions of this Agreement will apply
mutatis mutandis to such unregistered offering, including, without limitation,
provisions relating to Joining Notices, Quintiles's ability to delay an
offering, allocations of securities included in an offering, Quintiles's
obligations with respect to an offering (including indemnification provisions
and procedures), selection of underwriters, hold-back agreements, expenses
associated with an offering and representations and warranties.

<PAGE>   113
SECTION 10.  PRIORITY OF HOLDERS

             Until the end of the Demand Period, the following conditions shall
apply (subject to waiver by the Required Holders); Quintiles shall use
reasonable efforts to cause Dr. Dennis B. Gillings (i) not to sell or otherwise
transfer shares other than (A) to a private transferee which agrees to be bound
by these provisions or (B) to the public in an amount and manner specified in
Rules 144(e) and (f), respectively, of the Regulations, regardless of the
applicability of such rules to a proposed transfer and (ii) if requested by the
managing underwriter or underwriters in an underwritten offering, not to effect
any public sale or distribution of any securities of Quintiles being registered,
or any similar security of Quintiles, or any securities convertible or
exchangeable or exercisable for such securities including sales pursuant to Rule
144 (except in each case as part of such underwritten offering), during the
period beginning 30 days prior to, and ending 120 days after, the closing date
of each underwritten offering made pursuant to such Registration Statement, to
the extent timely notified in writing by Quintiles or by the managing
underwriter of such underwritten offering.

SECTION 11.  MISCELLANEOUS

             (a) Remedies. In the event of breach by any party of any of its 
obligations under this Agreement, the other parties, in addition to being
entitled to exercise all rights provided herein or granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement. Quintiles and each Holder agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by Quintiles or such Holder, as the case may be, of any of the provisions of
this Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, Quintiles or such Holder, as the
case may be, shall waive the defense that a remedy at law would be adequate. No
failure or delay on the part of Quintiles or any Holder in exercising any right,
power or remedy hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right, power or remedy preclude any other
or further exercise thereof or the exercise of any other right, power or remedy.

             (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless Quintiles has obtained the written consent of Holders
of at least 90% of the then outstanding Registrable Securities. Notwithstanding
the foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holders of
Registrable Securities whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect, impair,
limit or compromise the rights of other Holders of Registrable Securities may be
given by Holders of at least a majority of the Registrable Securities being sold
by Holders pursuant to such Registration Statement; provided, however, that the
provisions of this sentence may not be amended, modified or supplemented except
in accordance with the provisions of the immediately preceding sentence.

purposes only and shall not affect in any way the meaning or interpretation of

                  (e) Counterparts. This Agreement may be executed in two or

                  (f) Entire Agreement; No Third Party Beneficiaries. This
Agreement (including the documents and the instruments referred to herein) (i)
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof, and (ii) except as contemplated by the definition of
"Holders" in Section 1 hereof, is not intended to confer upon any Person other
than the parties hereto any rights or remedies hereunder.

                  (G) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, USA, WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

                  (h) Severability. Wherever possible, each provision hereof
shall be interpreted in such a manner as to be valid, legal and enforceable
under applicable law, but in case any one or more of the provisions contained
herein shall, for any reason, be held to be invalid, illegal or unenforceable in
any respect, such provision shall be ineffective to the extent, but only to the
extent, of such invalidity, illegality or unenforceability without invalidating
or rendering unenforceable the remainder of this Agreement, unless such a
construction would be unreasonable or materially impair the rights or any party
hereto.

                  (i) Assignment. Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties
hereto (whether by operation of law or otherwise) without prior written consent
of the other parties, except as may otherwise occur by operation of the
definition of "Holders" in Section 1 hereof or to another Holder who, by such
assignment, agrees to be bound by the restrictions set forth herein. Subject to
the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties hereto and their respective
successors and assigns.

                  (j) Attorney's Fees. As between parties to this Agreement, in
any action or proceeding brought to enforce any provision of this Agreement, or
where any provision hereof is validly asserted as a defense, the successful
party shall be entitled to recover reasonable attorney's fees in addition to its
costs and expenses and any other available remedy.

                  (k) Use of Terms. This Agreement contemplates the filing of
Registration Statements under the Securities Act on numerous occasions involving
various offers of securities. In connection with such Registration Statements,
there may be identified therein one or more underwriters through which
securities are to be offered on behalf of Quintiles or one or more of the
Holders, or both, pursuant to either a "firm-commitment" or "best-efforts"
arrangement, and, in the case where there is more than one underwriter, one or
more of the underwriters may be designated as the "manager" or "representative"
or the "co-managers" or "representatives" of the several underwriters.
Accordingly, all references herein to an "underwriter" or "underwriters" are
intended to refer to a "principal underwriter" (as defined in Rule 405 of the
Regulations) and to provide for those transactions in which securities may be
offered by or through one or more underwriters, and not to imply that any of the
transactions contemplated

                                      -26-

hereby is conditioned in any manner whatsoever on the participation therein by
one or more underwriters on behalf of any party. Nothing contained herein
relating to Quintiles's obligation to enter into an underwriting agreement at
any time or from time to time in the future shall impair, alter, restrict or
otherwise affect in any manner whatsoever the duties of the Board of Directors
of Quintiles under applicable law in approving the form, terms and provisions
thereof.

                  IN WITNESS WHEREOF, the parties have executed this Agreement
as of the date first written above.
