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
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
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).

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

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

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

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

hereunder and thereunder and to consummate the transactions contemplated hereby

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.

Each Innovex Subsidiary has the corporate power and authority to own, lease and

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

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

7
13

there are no material intercompany transactions between or among
Innovex and any Innovex Subsidiaries and no transactions between

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

and June 30, 1996 and designated as delivered pursuant to this Section
(the "Innovex Interim F-1 Financial Statements," and together with the

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 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).

projections, all designated as delivered pursuant to this Section. Such
financial

8
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

Acts or any other applicable Law to be filed with the Registrar of Companies,

with all the provisions of such Laws in connection with the formation of
Innovex and each Innovex Subsidiary, the allotment or issue of shares,

assets, taken as a whole, are in a state of good maintenance and repair and are
adequate and suitable for the purposes for which they are currently being used.

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

Neither Innovex nor any Innovex Subsidiary has violated any of the material
terms or conditions under any lease set forth in Schedule 2.11 (or required to

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
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

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
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
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 Xxxxxxxxx Xxx 0000 ("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
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
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 xxxx 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
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

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
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.

(a) Quintiles has furnished Innovex with the consolidated
balance sheets of Quintiles and its Subsidiaries as of December 31, 1995 (the
"Quintiles Balance Sheet") and December 31, 1994, and the related statements of
income, statements of cash flows, and statements of shareholders' equity for
the years then ended, all audited by Ernst & Young LLP (collectively, the
"Quintiles Audited Financial Statements") and designated as delivered pursuant
to this Section. Quintiles also has furnished Innovex with the unaudited
consolidated balance sheets of Quintiles and its Subsidiaries as of June 30,
1996 and the related unaudited consolidated statements of income, statements of
cash flows, and statements of shareholders' equity for the six months then
ended, and will furnish Innovex with the unaudited consolidated balance sheets
of Quintiles and its Subsidiaries as of September 30, 1996 and the related
unaudited consolidated statements of income, statements of cash flows, and
statements of shareholders' equity for the nine months then ended
(collectively, the "Quintiles Interim Financial Statements"). Further,
Quintiles will provide to Innovex, 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

23
29

Closing Date falls on the 25th or any later day of a month), unaudited
management accounts for Quintiles and its Subsidiaries for such calendar month
(collectively, the "Quintiles Management Accounts," and together with the
Quintiles Audited Financial Statements and the Quintiles Interim Financial
Statements, the "Quintiles Financial Statements"). All of the Quintiles
Financial Statements, including the notes thereto, have been and will be
prepared in accordance with United States Generally Accepted Accounting
Principles, consistently followed throughout the periods indicated, except that
the Quintiles Interim Financial Statements and the Quintiles Management
Accounts are subject to normal, recurring adjustments (which will not be
material individually or in the aggregate) and lack footnotes and other
presentation items and are presented in a summary format. The Quintiles
Balance Sheet, all such other balance sheets, and all comparable information
included in the Quintiles Management Accounts fairly present, or will fairly
present, the financial condition of Quintiles and its Subsidiaries on a
combined basis at the respective dates thereof; and the related statements of
income, statements of cash flows and statements of shareholders' equity (if
applicable), and comparable information included in the Quintiles Management
Accounts fairly present, or will fairly present, the results of the operations
of Quintiles and its Subsidiaries on a consolidated basis and the changes in
their financial position for the periods indicated. There are no material
intercompany transactions between or among Quintiles and any Quintiles
Subsidiaries not reflected in the Quintiles Financial Statements.

(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
nor any of its Subsidiaries has any liabilities or obligations of any nature
(whether accrued, absolute, contingent or otherwise) which, individually or in

from consulting with its legal and financial advisors and its independent
accountants regarding the feasibility of a Public Offering in the event that

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.

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
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 Xxxxxxx Xxxxx & Co. and Xxxxx Xxxxxx
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

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
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.

52

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

(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

further divisions of Quintiles will also be formed subsequent to the Closing,
comprising the Quintiles division (focusing on clinical research) and the Xxxxx
division (concentrating on managed care).

(ii) Strategic Focus. The Innovex Division will
have the strategic focus of supplying outsourcing services to the

executive management team. The CEO of the Innovex Division shall report to the
COO of Quintiles.

of this Agreement, Quintiles and Innovex will establish a committee (the

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.

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
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
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
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.

(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.

assigned to such terms in the Share Exchange Agreement), providing for the
exchange of all of Innovex's issued and outstanding ordinary and preferred
ordinary share capital for shares of Common Stock of Quintiles (the "Quintiles
Shares"), to be allocated among the Shareholders as provided in the Share
Exchange Agreement;

WHEREAS, pursuant to the Share Exchange Agreement, Quintiles, Innovex
and the Shareholders have agreed that the rights of indemnification of the
Indemnitees (as defined in the Share Exchange Agreement) under Article VIII of
the Share Exchange Agreement shall survive the consummation of the transactions
contemplated by the Share Exchange Agreement and shall be secured, pursuant to
this Agreement, by the portion of Quintiles Shares to be deposited in escrow
with the Escrow Agent pursuant to Section 1.3 of the Share Exchange Agreement
(such Quintiles Shares, together with any accumulations thereto as provided
herein, the "Escrow Shares"); and

WHEREAS, the Escrow Agent is willing to act in the capacity of escrow
agent hereunder subject to, and upon the terms and conditions of this
Agreement.

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, and as an inducement for
the execution and delivery of the Share Exchange Agreement, Quintiles, the

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

date hereof and prior to the distribution of the Escrow Shares either (i) by
delivery to the Shareholders in accordance with Article III hereof or (ii) by
delivery to Quintiles in accordance with Article IV hereof, or by a combination
of (i) and (ii), if any of the Shareholders shall become entitled to receive or
shall receive in connection with the Escrow Shares any (i) non-taxable
distribution of securities of Quintiles or of any other entity including,
without limitation, any certificate in connection with any increase or
reduction of capital, reclassification, recapitalization, merger, business
combination, consolidation, sale of assets, stock split-up or spin-off; or (ii)
any non-taxable distribution of stock options, warrants or rights, whether as
an addition to or in substitution of or exchange for any of

2
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,
stock option, warrant, right or stock dividend shall be deemed to be Escrow
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
paid with respect to the Escrow Shares shall be paid to the Shareholders in
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 cash dividends which such Shareholder is entitled to receive and shall, for
any non-cash dividend and any other non-taxable distribution, execute stock
powers or other appropriate instruments of transfer for all shares, options,
warrants or rights as required for transfer hereunder.

2.3. Retained Voting and Other Rights. The Escrow Agent shall hold
the Escrow Shares and any additional property acquired with respect thereto
pursuant to Section 2.2 above in safekeeping and dispose thereof only in
accordance with the terms of this Agreement. The Escrow Agent shall hold the
Escrow Shares in accordance with each Shareholder's proportionate interest in
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
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
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
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
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.

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-

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-

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 Xxxxxxx, Xxxxx & 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-

(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
Quintiles to file a Registration Statement under the Securities Act for a Public
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
shares of Common Stock previously sold by

-8-

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-

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-

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-

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

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

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

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.

-12-

102

(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
authorized herein or in the event of a Blackout Period or Shelf
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.

(e) Use its best efforts to register or qualify the
Registrable Securities covered by such Registration Statement under
such securities or blue sky laws of such jurisdictions in the United
States as the Sellers participating in the Public Offering or the

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.

(f) Make available upon reasonable advance notice for
inspection by any Seller of such Registrable Securities, any
underwriter participating in any disposition pursuant to such
Registration Statement and any attorney, accountant or other
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
shall be reasonably necessary to enable them to conduct a "reasonable"
investigation for purposes of Section 11(a) of the Securities Act and
cause Quintiles's officers, directors and employees to supply all
information reasonably requested by any Inspectors in connection with
such Registration Statement.

(g) Use its best efforts to cause all Registrable Securities
covered by such Registration Statement to be (A) qualified for trading

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
supplement thereto (in each case including all exhibits

-13-

Preliminary Prospectus) and such other documents as such Holder or
underwriter may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such Seller.

(i) In connection with an underwritten offering of Registrable
Securities, enter into an underwriting agreement in such form as is
customary in underwritten offerings made by selling security holders
and take all such other actions as are reasonably requested by the

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

which financial statements and financial data are, or are required to

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

-14-

104

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

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

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

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

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,

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.

reports required to be filed by it under the Securities Act and the
Exchange Act, will make available "adequate

-17-

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

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

(i) Such Holder, if not a natural person, is duly
organized, validly existing, and in good standing under the laws of its

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.

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.

-18-
108
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-
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-

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-

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-

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.

-23-
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 Xx. Xxxxxx X. Xxxxxxxx (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.

(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

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.
