ITEM 5.  OTHER EVENTS.

         On January 5, 1999, Quintiles announced the completion of its
previously announced acquisition of substantial assets of Hoechst Marion
Roussel's Kansas City-based Drug Innovation and Approval facility and the
opening of a Kansas City contract research facility. A copy of the Agreement for
the Provision of Research Services and Purchase of Business Assets between
Hoechst Marion Roussel, Inc. and Quintiles, Inc. is attached hereto as
Exhibit 10.01 and incorporated herein by reference.

         In connection with certain acquisitions accounted for as pooling of
interests which were consummated between January 1, 1996 and September 30, 1998,
Quintiles Transnational Corp. (the "Company") has restated certain of its
historical consolidated financial data, as included in the Company's Current
Report on Form 8-K dated January 27, 1999, and provides the restated selected
consolidated financial data table below.

                      SELECTED CONSOLIDATED FINANCIAL DATA

The selected Consolidated Statement of Income Data set forth below for each
of the years in the three-year period ending December 31, 1997 and the
Consolidated Balance Sheet Data set forth below as of December 31, 1996 and 1997
are derived from the audited consolidated financial statements of the Company
and notes thereto, as restated for certain pooling transactions, included in
this Current Report on Form 8-K dated January 27, 1999. The selected
Consolidated Statement of Income Data set forth below for the years ended
December 1994 and 1993, and the Consolidated Balance Sheet Data set forth below
as of December 31, 1995, 1994 and 1993 are derived from the audited consolidated
financial statements of the Company as subsequently restated for certain pooling
transactions. The data provided as of September 30, 1998 and for the nine months
ended September 30, 1997 and 1998 are derived from unaudited consolidated
financial statements included in the Company's Quarterly Report on Form 10-Q for
the period ended September 30, 1998, as subsequently restated herein for certain
pooling transactions, but in the opinion of management, contain all adjustments,
consisting only of normal recurring accruals, which are necessary for a fair
statement of the results of such periods. The consolidated financial statements
of the Company have been restated to reflect material acquisitions by the
Company in transactions accounted for as poolings of interests. However, the
consolidated financial statements have not been restated to reflect certain
other acquisitions accounted for as pooling of interests where the Company
determined that the consolidated financial data would not have been materially
different if the pooled companies had been included. For such immaterial pooling
of interests transactions, which include two transactions in 1997 and two
transactions in 1996, the Company's financial statements for the year of each
transaction have been restated to include the pooled companies from January 1 of
that year, but the financial statements for years prior to the year of each
transaction have not been restated because the effect of such restatement would
be immaterial. The selected consolidated financial data presented below should
be read in conjunction with the Company's audited and unaudited consolidated
financial statements and notes thereto and "Management's Discussion and Analysis
of Financial Condition and Results of Operations" included herein.

(1)      Prior to the Company's November 29, 1996 share exchange with Innovex
         Limited (Innovex), Innovex had a fiscal year end of March 31 and the
         Company had (and continues to have) a fiscal year end of December 31.
         As a result, the pooled data presented above for 1993 through 1995
         include Innovex's March 31 fiscal year data in combination with the
         Company's December 31 fiscal year data. In connection with the share
         exchange, Innovex changed its fiscal year end to December 31.
         Accordingly, the pooled data presented above for 1996 include both
         Innovex's and the Company's data on a December 31 year end basis.
         Because of the difference between Innovex's fiscal year end in 1995
         compared with 1996, Innovex's quarter ended March 31, 1996 data are
         included in the Company's pooled data for both 1995 and 1996.
(2)      Restated to reflect the two-for-one stock splits of the Company's
         Common Stock effected as a 100% stock dividend in November 1995 and
         December 1997.

         On February 12, 1999, Kenneth Hodges ("Plaintiff") filed a civil
lawsuit in the State Court of Fulton County Georgia naming as defendants Richard
L. Borison, Bruce I. Diamond, BASF Corporation, Pfizer, Inc., Merck & Company,
Inc., Wyeth-Ayerst Laboratories Company, Zeneca, Inc., Janssen Pharmaceutica
Inc., Smithkline Beecham Corporation, Hoechst Marion Roussel, Inc., Glaxo
Wellcome, Inc., Abbott Laboratories, Bristol-Myers Squibb Company,
Warner-Lambert Company, Monsanto Company, Novartis Pharmaceuticals Corporation
and Quintiles Laboratories Limited, a subsidiary of the Company. The complaint
alleges that certain drug trials conducted by Drs. Borison and Diamond in which
Plaintiff alleges he participated between 1988 and 1996 were not properly
conducted or supervised, that Plaintiff had violent adverse reactions to many of
the drugs and that his schizophrenia was aggravated by the drug trials.
Consequently, Plaintiff alleges that he was subject to severe mortification,
injured feelings, shame, public humiliation, victimization, emotional turmoil
and distress. The complaint alleges claims for battery, fraudulent inducement to
participate in the drug experiments, medical malpractice, negligence in
conducting the experiments, and intentional infliction of emotional distress.
Plaintiff seeks to recover his actual damages in unspecified amounts, medical
expenses, litigation costs, and punitive damages.

         Nowhere in the complaint are found any specific allegations against 
Quintiles Laboratories Limited nor any specific factual connection between the
Company and the Plaintiff's claims. The Company believes the claims alleged
against it are vague and meritless, and the recovery sought is baseless. The
Company intends to vigorously defend against these claims.

         2.6      ASSIGNMENT OF THE ASSUMED CONTRACTS; RELATED MATTERS

                  (a)      HMR shall use commercially reasonable efforts to
                           have the Assumed Contracts assigned to Quintiles,
                           and Quintiles shall cooperate with HMR to facilitate
                           such assignment. In the event that any Assumed
                           Contract(s) cannot be assigned to Quintiles, then
                           HMR shall, at the request of Quintiles and after
                           consultation between Quintiles and HMR, either (i)
                           terminate such Assumed Contract(s) at Quintiles'
                           cost (including any



                                      12

                           termination or other cost resulting from
                           termination) or, (ii) if permitted thereunder,
                           continue the Assumed Contract(s) for the benefit of
                           Quintiles for the remainder of the unexpired term of
                           such Assumed Contract(s), in which case Quintiles
                           shall fully perform all of the obligations under
                           such Assumed Contract(s) arising after the date of
                           Closing and unrelated to HMR's performance of such
                           Assumed Contracts prior to the date of Closing,
                           including payment of rent and other expenditures;
                           provided, however, if any Assumed Contract is not
                           permitted to be continued by HMR for the benefit of
                           Quintiles, then HMR shall remain responsible for any
                           continuing payments or costs of termination under
                           such Assumed Contract. To the extent that Quintiles
                           cannot obtain the use of any such Leased Property
                           pursuant to this Section 2.6 and to the extent such
                           Leased Property is necessary to provide the Reserved
                           Capacity, (i) Quintiles shall use its best efforts
                           to replace such Leased Property, and (ii) until such
                           Leased Property is replaced, Quintiles shall be
                           excused from the performance of Research Services
                           impacted by such Leased Property.

                  (b)               HMR shall use commercially reasonable
                           efforts to permit use by Quintiles of, and if
                           applicable to convey its interest in, the Leased
                           Property held by HMR pursuant to vendor agreements,
                           other than the Assumed Contracts, which cannot be
                           assigned to Quintiles because HMR is retaining the
                           benefit of such agreement for its ongoing operations
                           (the "Retained HMR Contracts"). In consideration
                           thereof, Quintiles shall reimburse HMR for its pro
                           rata costs under such agreements relating to



                                      13

                           such Leased Property pursuant to periodic invoices
                           from HMR. To the extent that Quintiles cannot obtain
                           the use of any such Leased Property pursuant to this
                           Section 2.6 and to the extent such Leased Property
                           is necessary to provide the Reserved Capacity, (i)
                           Quintiles shall use its best efforts to replace such
                           Leased Property, and (ii) until such Leased Property
                           is replaced, Quintiles shall be excused from the
                           performance of Research Services impacted by such
                           Leased Property.

         2.7      REAL ESTATE

                  (a)      On the date of Closing, Quintiles shall pay to HMR
                           by wire transfer of immediately available funds the
                           sum of $* as a non-refundable earnest money
                           deposit payment for the Facility, as contemplated by
                           the Real Estate Sale Agreement.

                  (b)               Subject to the provisions of the Real 
                           Estate Sale Agreement, on the date of Real Estate
                           Closing, Quintiles shall pay to HMR by wire transfer
                           of immediately available funds the remaining
                           purchase price of $* for the Facility.

                           The Guaranteed Revenue for any year shall be
                           adjusted for inflation occurring after December 31,
                           1998 and through the first day of such year using
                           the Employment Cost Index for total compensation for
                           private industry workers in service occupations
                           excluding sales, published by the Bureau of Labor
                           statistics; provided if at any time such index is no
                           longer published, then the Steering Committee shall
                           choose such published index as they shall agree is
                           most similar thereto. Notwithstanding the foregoing,
                           no such adjustment shall be made to the amount of
                           the Guaranteed Revenue payable in 1999.

                  (b)      HMR shall offer Quintiles the opportunity to perform
                           all Research Services during the Initial Period up
                           to the Offer Limit. All Research Services shall be
                           provided pursuant to Letter Agreements that state on
                           their face (subject to actual payment at different
                           rates in cases involving Reserved Capacity or other
                           Research Services up to the Offer Limit, as set
                           forth herein below) financial terms based on
                           Quintiles' Prevailing Competitive Rates (defined as
                           the average rates at which Quintiles wins business
                           in the United States comparable to the Projects);
                           provided, however notwithstanding anything to the

                           Revenue will be credited against all Research
                           Services that utilize Reserved Capacity at the Price
                           Per Output Unit as defined in Section 3.8, and not
                           at Quintiles Prevailing Competitive Rate as stated
                           in the Letter Agreement, and such credits at the
                           Price Per Output Unit shall be reflected in the
                           reconciliation process and the payment calculation
                           as each is described in Section 3.4; and (ii)
                           payments for Research Services that do not utilize
                           Reserved Capacity shall be adjusted for any
                           applicable discount as set forth herein below in
                           this Section 3.1(b) and such discount shall be
                           reflected in the reconciliation process and the
                           payment calculation as each is described in Section
                           3.4. The Steering Committee shall review and
                           confirm, from time to time, that the rates being
                           charged by Quintiles (before adjustment for any
                           applicable discount as set forth herein below in
                           this Section 3.1(b)) for Research Services (other
                           than Research Services that utilize Reserved
                           Capacity) constitute its then Prevailing Competitive
                           Rates, and Quintiles shall provide such support
                           therefor as may be reasonably requested by HMR's
                           member representatives on the Steering Committee.
                           HMR's obligation to offer Quintiles the opportunity
                           to perform Research Services terminates as to any
                           year when HMR shall have paid (or be deemed to have
                           paid in accordance with Section 3.5) to Quintiles an

                           Research Services, such amount for any given year

                           and such amount as adjusted being referred to
                           hereinafter as the "Offer Limit"). HMR may, but
                           shall have no obligation to, offer Quintiles the
                           opportunity to perform Research Services that become
                           part of HMR's pipeline of projects as a result of
                           any merger, consolidation or other combination after
                           the date hereof. Up to the Offer Limit, HMR shall
                           offer Quintiles the opportunity to perform all

                           will as a result of a signed agreement, become
                           owned, leased, licensed, controlled or beneficially

                           consolidation or other combination after the date
                           hereof. Payments for Research Services in excess of
                           the Guaranteed Revenue, up to a maximum of the Offer
                           Limit, shall be reduced by the following applicable

                           During the Initial Period, once HMR has paid the
                           Offer Limit for any particular year, HMR and
                           Quintiles shall have a non-exclusive preferred
                           provider/customer relationship; provided however,
                           HMR shall have no

                           obligation by virtue of such relationship to offer
                           Quintiles, nor shall Quintiles have any obligation
                           by virtue of such relationship to accept, the
                           opportunity to perform additional Research Services
                           for such year.

                  (c)      After the Initial Period, Quintiles shall have no
                           obligation under this Agreement to provide Research
                           Services to HMR and HMR shall have no obligation to
                           purchase or offer to purchase Research Services from
                           Quintiles, except pursuant to Letter Agreements or
                           other contractual obligations then existing.

         3.2      RESERVED CAPACITY

                  (a)      Quintiles shall employ at the Facility personnel in
                           numbers and expertise in the departments of the
                           relevant areas of study conducted at the Facility as
                           of the date of Closing (namely biodynamics, drug
                           regulatory affairs, data management, pharmaceutics,
                           analytics, drug metabolism & pharmacokinetics and
                           clinical operations (the "Relevant Departments"))
                           such that Quintiles has the capacity to provide
                           Research Services equivalent to the * Output (the
                           "Reserved Capacity"). The initial allocation of the
                           Reserved Capacity among each Relevant Department
                           shall be determined by the Steering Committee based
                           on each Relevant Department's contribution to *
                           Output. If Quintiles expands its expertise and areas
                           of study from those identified as the Relevant
                           Departments, Quintiles and HMR may (but shall be
                           under no obligation to) agree that any and all such
                           expanded expertise and areas of study be included
                           within the defined term "Relevant Departments". In
                           any such 



                                      18
<PAGE>   24

                           case, the Steering Committee shall determine for
                           purposes of Section 3.8 below the Price Per Output
                           Unit to be associated with any output that may
                           result from the expanded expertise or areas of study
                           and shall reallocate the Reserved Capacity among the
                           Relevant Departments, as newly constituted.
                           Similarly, the Steering Committee shall regularly
                           evaluate the Relevant Departments to determine
                           whether it would be in both parties' interests to
                           eliminate any Relevant Department or to reallocate
                           the Reserved Capacity among the Relevant Departments
                           and, if so determined, reallocate the Reserved
                           Capacity appropriately.

                  (b)      The annual Reserved Capacity for each Relevant 
                           Department shall be divided by twelve (12) to
                           calculate the monthly Reserved Capacity for each
                           Relevant Department. HMR shall endeavor to offer
                           Quintiles the opportunity to perform Research
                           Services in a manner that fully and reasonably
                           utilizes the monthly Reserved Capacity for each
                           Relevant Department. HMR's failure to offer
                           Quintiles the opportunity to perform Research
                           Services in a manner that fully utilizes the
                           Reserved Capacity for each Relevant Department in
                           any month shall not affect the right of Quintiles to
                           receive and retain the entire monthly payment of
                           Guaranteed Revenue. For the avoidance of doubt, to
                           the extent HMR does not, for any reason, offer
                           Quintiles the opportunity to perform Research
                           Services in a manner that reasonably utilizes the
                           entire monthly allocation of Reserved Capacity for
                           any Relevant Department, Quintiles shall (i) have no
                           obligation to perform Research Services with respect
                           to such nonutilized

                           Research Capacity and (ii) be deemed to have earned
                           and be entitled to retain all of the Guaranteed
                           Revenue for the relevant month. Such event shall not
                           confer on Quintiles any right to terminate this
                           Agreement and Quintiles' sole and exclusive remedy
                           for HMR's failure to offer such opportunities in a
                           manner that utilizes the monthly Reserved Capacity
                           shall be to retain the corresponding Guaranteed
                           Revenue without any obligation to perform Research
                           Services with respect to such nonutilized Reserved
                           Capacity. HMR shall be deemed to offer Quintiles the
                           opportunity to perform Research Services in a manner
                           that reasonably utilizes the Reserved Capacity if
                           such services could be performed utilizing Reserved
                           Capacity (not then already utilized by Projects),
                           and such Services could be performed with similar
                           available capacity and upon the terms being
                           requested by HMR either in-house or by another
                           contract research organization in the ordinary
                           course of its business.

                  (c)      Attached as Schedule 3.2(c) is a list of 
                           approximately 25 Transferring Employees who are
                           expected to become employees of Quintiles and who
                           are to be assigned duties by Quintiles as described
                           below (the "Dedicated Employees"). HMR may designate
                           up to 10 additional non-manager level Transferring
                           Employees as additional "Dedicated Employees." The
                           Dedicated Employees identified on Schedule 3.2(c) as
                           managers shall be made available to HMR on a
                           reasonable first priority basis as necessary for HMR
                           to access key corporate memory. Unless otherwise
                           agreed to by HMR in writing, the non-manager
                           Dedicated Employees shall be assigned



                                      20
<PAGE>   26

                           to Projects exclusively. The Steering Committee
                           shall review the utilization of such Dedicated
                           Employees quarterly, and temporarily release any
                           Dedicated Employees from the foregoing commitments
                           or add new Dedicated Employees as appropriate such
                           that the total number of Dedicated Employees does
                           not exceed 35 (and the number of managers does not
                           exceed the original number of managers set forth on
                           Schedule 3.2(c)). The Steering Committee shall
                           attribute to each Dedicated Employee a constant
                           output level for his or her services (and a
                           corresponding Price Per Output Unit) which shall be
                           counted as Research Services (except with respect to
                           periods during which such Dedicated Employee is
                           released from the foregoing commitments). Such
                           constant output level will be based upon the
                           assumption that the Dedicated Employee is working at
                           full capacity (whether or not the Dedicated Employee
                           is actually working at full capacity).

         3.3      TERMS OF PROJECTS

                  (a)               The terms and conditions applying to each  
                           Project will be as set forth in (i) the Master
                           Services Agreement and (ii) a separate Letter
                           Agreement in which the services to be performed and
                           the results to be achieved will be defined in detail
                           and agreed upon by both parties. Each Letter
                           Agreement will define material items, which may
                           include detailed tasks, a description of the
                           expected results, quality goals, timelines,
                           milestones, fixed budgets and provisions for dealing
                           with change orders. In addition, each Letter
                           Agreement will contain payment terms based on a



                                      21
<PAGE>   27

                           set of milestones, including a completion milestone
                           and a meaningful final payment, in a manner that the
                           parties intend to be cash neutral to Quintiles when
                           considering all Letter Agreements in the aggregate.
                           Payment terms of any Letter Agreement shall in no
                           way qualify or affect HMR's obligation to pay the
                           Guaranteed Revenue in accordance with Section
                           3.4(a).


                  (b)               If Quintiles is offered an opportunity to
                           perform Research Services and does not respond to
                           HMR within 14 days after delivery of such offer,
                           then HMR shall notify in writing one of Quintiles'
                           Steering Committee representative members of such
                           offer. If HMR does not receive written confirmation
                           from Quintiles within seven days after delivery of
                           notification to such member, then Quintiles shall be
                           deemed to have rejected such offer.

                  (c)               If the parties fail to enter into a Letter
                           Agreement within 30 days after acceptance by
                           Quintiles of an offer to perform Research Services,
                           then any matter in dispute respecting such Letter
                           Agreement shall be referred to the Steering
                           Committee for resolution in accordance with the
                           terms of this Agreement. The Steering Committee
                           shall also resolve any dispute of whether an offer
                           constitutes reasonable utilization of the Reserved
                           Capacity.


         3.4      PAYMENT FOR RESEARCH SERVICES 

                  (a)               Quintiles shall invoice HMR for the 
                           Guaranteed Revenue due each year in equal monthly
                           installments on the first business day of each
                           month, 



                                      22
<PAGE>   28

                           commencing in January 1999. HMR shall pay each such
                           invoice to Quintiles by the seventh business day of
                           such month. The obligation of HMR to make such
                           payments shall not be conditioned upon Quintiles
                           being offered by HMR the opportunity to perform
                           Research Services. Notwithstanding anything in this
                           Agreement to the contrary, HMR may terminate its
                           obligation to pay the Guaranteed Revenue only by
                           exercising one of its express rights to terminate
                           this Agreement under Article 8 below.

                  (b)               The Guaranteed Revenue and the Offer Limit
                           shall exclude any third-party costs for which
                           Quintiles is reimbursed without mark-up in
                           accordance with the terms of the relevant Letter
                           Agreement including, but not limited to,
                           investigator costs, travel expenses, Investigational
                           Review Board/Ethics Committee fees, investigator
                           meeting expenses, focus panel costs, costs of
                           advertising for patients, and submission and filing
                           fee, and any other payments to third parties passed
                           through to HMR which payments (if any) shall be made
                           in accordance with the terms of the relevant Letter
                           Agreement. Notwithstanding the foregoing, HMR shall
                           in 1999 receive a credit against actual pass-through
                           billable expenses incurred by Quintiles for Projects
                           in the amount of those project-related and billable
                           travel and entertainment expenses that the Steering
                           Committee concludes are included in the Financial
                           Schedule referred to in clause (i) of Section 12 of
                           Schedule 4.2 for 1999, provided that Reserved
                           Capacity and the corresponding Guaranteed Revenue
                           shall be reduced by the amount of



                                      23
<PAGE>   29

                           such credit. HMR shall receive a similar credit in
                           each of the years 2000 through 2002, the amount of
                           which shall be a percentage of the 1999 credit
                           adjusted for inflation using the methodology set
                           forth in Section 3.1(a), as follows: (i) *% in
                           2000, (ii) *% in 2001 and (iii) *% in 2002, and in
                           each such year reductions shall be made in Reserved
                           Capacity and Guaranteed Revenue in amounts equal to
                           such credit.

                  (c)      Promptly following the execution of this Agreement,
                           the parties shall establish a process by which
                           amounts due under the Letter Agreements and this
                           Agreement will be reconciled, on a monthly basis,
                           with the rights and obligations set forth herein.
                           The purpose (among others) of such reconciliation
                           process shall be to determine the extent to which
                           Research Services rendered during a given month
                           utilize Reserved Capacity for such month (crediting
                           Guaranteed Revenue at the Price Per Output Unit
                           against Research Services that utilize Reserved
                           Capacity as described in Section 3.1(b)) to
                           determine what, if any, additional amounts are
                           payable to Quintiles for such Research Services.
                           Such reconciliation process shall account for, among
                           other factors, with respect to each Relevant
                           Department for the relevant month: the amount of the
                           Reserved Capacity utilized by HMR; the amount of any
                           Permitted Carryover; the amount, if any, of Research
                           Services that do not utilize Reserved Capacity; and
                           the application of any discount provided for in
                           Section 3.1(b) to the amounts payable to Quintiles
                           for Research Services that do not utilize Reserved
                           Capacity. At the end of each month, Quintiles shall



                                      24
<PAGE>   30

                           prepare, and deliver to HMR, a separate monthly
                           invoice reflecting such reconciliation process for
                           each ongoing Project. Any amount reflected as
                           remaining due to Quintiles after such reconciliation
                           process shall be paid by HMR within thirty (30) days
                           after receipt of an invoice prepared pursuant to the
                           reconciliation, except to the extent disputed in
                           good faith by HMR in accordance with this Agreement.
                           HMR shall have the right to audit upon reasonable
                           request Quintiles' adherence to, and implementation
                           of, such reconciliation process.

                  (d)               When used herein, the term "Permitted 
                           Carryover" shall mean, with respect to each Relevant
                           Department, HMR's right to apply an up to ten
                           percent (10%) cumulative shortfall or excess in
                           utilization of the monthly Reserved Capacity for
                           such Relevant Department against a future month's
                           corresponding excess or shortfall, respectively. A
                           Permitted Carryover for any given month may be
                           continued from month-to-month but in no event shall
                           the cumulative Permitted Carryover for all months
                           ever exceed an amount equal to ten percent (10%) of
                           the Reserved Capacity for the Relevant Department
                           for one month. The existence of a Permitted
                           Carryover does not relieve HMR from paying the
                           regular monthly payment of the Guaranteed Revenue
                           for months in which a Permitted Carryover exists.

         3.5      REDUCTIONS OR ALTERATIONS IN HMR'S COMMITMENTS

                  (a)               If Quintiles rejects an offer to perform
                           Research Services for which it has capacity and
                           capability within the Reserved Capacity, HMR's



                                      25
<PAGE>   31

                  obligation to pay the Guaranteed Revenue for the months
                  during which such Research Services would have been performed
                  shall be reduced by the relevant Price Per Output Unit
                  multiplied by the projected output of such Research Services
                  in each relevant month. Such rejection shall not reduce the
                  Offer Limit or, in and of itself, grant to HMR any other
                  remedies hereunder. For purposes of this Agreement,
                  Quintiles' refusal to enter into a Letter Agreement (unless
                  resolution by the Steering Committee is pending in accordance
                  with Section 3.3(c)), or failure to respond to an offer to
                  perform Research Services as set forth in Section 3.3(b),
                  shall be deemed to be a rejection of an offer to perform
                  Research Services.

         (b)               If Quintiles rejects an offer to perform Research
                  Services for which it does not have capacity and capability
                  within the Reserved Capacity because such capacity and
                  capability is already fully utilized on other Projects, such
                  rejection (or deemed rejection) shall not reduce the
                  Guaranteed Revenue. However, if Quintiles had the capacity
                  and capability beyond the Reserved Capacity to enable it to
                  accept such offer, such rejection (or deemed rejection) shall
                  reduce the Offer Limit accordingly for such year.

         (c)               If any Research Services are postponed due to the
                  failure of Quintiles to perform in accordance with the terms
                  and conditions of the Letter Agreement relating to such
                  Research Services, such Research Services shall, for purposes
                  of determining utilization of the Reserved



                                      26
<PAGE>   32

                  Capacity, be considered to have been performed in the period
                  in which the performance was originally due. However, if any
                  Research Services are postponed due to HMR's actions, the
                  Research Services shall be considered to have been performed
                  in the period in which the work is actually performed.

         3.6      QUALITY-RELATED MATTERS

                  (a)      If the Steering Committee determines that HMR has
                           suffered damage because Quintiles has materially
                           failed to perform in accordance with the terms and
                           conditions applicable to any Letter Agreement, then
                           Quintiles will, within seven business days after
                           such determination, pay, subject to any limitations
                           in the Letter Agreement, the Master Services
                           Agreement, or this Agreement, to HMR compensation
                           for such breach as determined by the Steering
                           Committee. The amounts so paid shall not reduce the
                           amount previously paid or payable pursuant to
                           Section 3.1 as Guaranteed Revenue. Examples of
                           situations in which such a payment may (depending
                           upon the seriousness and materiality of Quintiles'
                           actions) be due may include, among others, the
                           failure of Quintiles to meet quality or timeliness
                           objectives or quality standards set forth in the
                           relevant Letter Agreement. This provision shall be
                           superseded to the extent the Master Services
                           Agreement provides specific corrective actions for
                           such events.

                  (b)      This Section 3.6(b) relates only to Research Services
                           offered to Quintiles under Section 3.1(b) which do
                           not utilize the Reserved



                                      27
<PAGE>   33

                           Capacity. HMR's obligation to offer such
                           opportunities is subject to HMR's reasonable
                           identification of a material deficiency in the
                           quality or timeliness of Research Services performed
                           previously by Quintiles, or in the ability of
                           Quintiles to perform the proposed Research Services,
                           which material deficiency HMR determines would
                           adversely impact the proposed Research Services. HMR
                           shall give written notice of such material
                           deficiency to Quintiles and Quintiles shall have the
                           opportunity to promptly provide adequate assurance
                           reasonably satisfactory to HMR that such identified
                           material deficiency has been remedied or otherwise
                           addressed. Until Quintiles has provided such
                           adequate assurance, HMR shall be relieved of its
                           obligation to provide to Quintiles the opportunity
                           to perform Research Services which are reasonably
                           expected to be affected by such material deficiency,
                           provided, however, that HMR's obligation under
                           Section 3.1(b) shall remain in effect for other
                           Research Services of a nature or type that are not
                           reasonably expected to be affected by such material
                           deficiency.

         3.7      RESEARCH SERVICES AT OTHER QUINTILES SITES; PRIOR ENGAGEMENTS

                  (a)               Research Services for which Reserved  
                           Capacity is available may be carried out by
                           Quintiles at Quintiles' sites other than the
                           Facility if the parties mutually agree in writing,
                           in which event such Research Services shall count
                           toward the utilization of the Reserved Capacity. If
                           the Reserved Capacity is fully utilized by Projects,
                           or if the Research Services



                                      28
<PAGE>   34

                           are not covered within the Relevant Departments,
                           then Quintiles may perform Research Services at any
                           Quintiles site located in the United States
                           reasonably selected by Quintiles (or any other
                           facility if mutually agreed by the parties in
                           writing) and the performance of such Research
                           Services shall not count toward utilization of the
                           Reserved Capacity.

                  (b)               Except as contemplated by this Agreement
                           or the Master Services Agreement, Research Services
                           or any other contract research services that were
                           purchased, ordered, or negotiated for purchase on or
                           prior to the date of Closing by HMR and/or its
                           Affiliates from Quintiles and/or its Affiliates
                           shall not be deemed Research Services, whether or
                           not such services are performed at the Facility
                           after the date of Closing.

         3.8      DEFINITION OF PRICE PER OUTPUT UNIT 

         The Research Services to be made available by Quintiles to HMR in
exchange for the Guaranteed Revenue shall be determined based on the amount and
nature of drug innovation and approval services provided by the Transferring
Employees of the Kansas City Drug Innovation and Approval Unit of HMR in *.
The foregoing shall be determined by reference to a list of factors for
measuring project-specific outputs that are attached to this Agreement as
Schedule 3.8. The Steering Committee shall, within 90 days of the Closing (the
"Assessment Period"), by selecting and giving appropriate weight to one or more
of the factors set forth on Schedule 3.8, or such other factors as the Steering
Committee deems appropriate because of situations where the list of factors is
not viewed as providing appropriate guidance, determine the amount and nature
of drug innovation and approval output provided by the Transferring Employees
of the Kansas City Drug Innovation and Approval unit of HMR in * (the "*
Output").

         As set forth in Section 3.2(a), the Steering Committee shall allocate
annually an appropriate portion of the total Reserved Capacity for the given
year to each Relevant Department (the "Departmental Reserved Capacity"). The
Steering Committee shall also allocate annually a corresponding proportion of
(i) the * Output to each Relevant Department (the "* Departmental Output"), and
(ii) the Guaranteed Revenue for the given year to each Relevant Department (the
"Departmental Guaranteed Revenue"). Following such allocations, the Steering
Committee shall establish, as of the beginning of each year, a rate card for
each Relevant Department for such year (the "Reserved Capacity Rate Card"). Each
Reserved Capacity Rate Card shall assign a rate to each person in the applicable
Relevant Department by allocating all Departmental Guaranteed Revenue for the
given year among employees, with appropriate distinction for compensation,
expertise, length of service and other relevant factors. 



                                      30
<PAGE>   36

The Steering Committee shall then determine on a general basis, which may be
varied as appropriate on a project-by-project basis due to distinguishing
factors, the allocation of labor (the "Resourcing Allocation") necessary to
complete given tasks or create specific deliverables ("Project Outputs"). The
Resourcing Allocation shall be ascertained by reference to, and shall be
consistent with, the resourcing allocations that were used to produce the
Project Outputs which, in the aggregate, created the * Departmental Output.
The product of the relevant chargeable rates from the Reserved Capacity Rate
Card and the Resourcing Allocation shall establish the charge for any given
unit of Project Output (a "Price Per Output Unit") during the given year.
Monthly billings under Letter Agreements should reflect the percentage of
completion of relevant Project Outputs to facilitate the reconciliation process
under Section 3.4(c). As Quintiles brings in new personnel resources to the
Facility, it shall have the option to provide the Reserved Capacity using
personnel not originally employed in any Relevant Department. Such personnel
shall be assigned a rate on the applicable Reserved Capacity Rate Card
consistent with the rates of the original department personnel having
comparable length of service, expertise, and other relevant factors. Except as
specifically set forth in Section 3.2(c) of this Agreement, Quintiles is not
required to provide the Reserved Capacity through any specific personnel. The
Steering Committee shall have flexibility from year to year to make appropriate
adjustments to the Reserved Capacity Rate Card so that the relative rates
assigned to all personnel in each department are appropriate; provided,
however, that any such adjustment shall satisfy the objective of maintaining
measurements that accurately track, for any given year: (i) HMR's utilization
of the Reserved Capacity, (ii) the corresponding allocation of Guaranteed
Revenue, and (iii) the availability of the Reserved Capacity.

         3.9      ESTABLISHMENT OF COMMITTEES

                  (a)               Upon execution of this Agreement, Quintiles
                           and HMR shall establish a liaison committee
                           ("Steering Committee") consisting of an equal number
                           of representative members from each company. HMR
                           shall designate one of its representative members as
                           Chairperson. The Steering Committee will, among
                           other things, plan, oversee and guide the drug
                           development process, discuss the status of current
                           and future Projects, review recommendations from the
                           Quality, Finance and Standards Committees, review
                           and confirm Prevailing Competitive Rates and resolve
                           any disputes between the parties or in the Quality,
                           Finance or Standards Committees.

                  (b)               The Steering Committee shall, if possible, 
                           make its decisions on a unanimous basis. If the
                           Steering Committee cannot reach a unanimity, then
                           decisions shall be determined in accordance with the
                           provisions of Article 13.

                  (c)               Formal quarterly meetings will be held by
                           the Steering Committee to ensure that operational
                           and financial performance and communications are
                           satisfactory to both HMR and Quintiles. At these
                           meetings, the Steering Committee will plan future
                           workload, discuss the status of current and future
                           Projects to be assigned to Quintiles, and approve an
                           operating plan for the following 12 months. Such an
                           operating plan will include estimates of resources
                           requirements and performance objectives, including
                           quality and financial targets. In addition, any
                           representative member of

                           the Steering Committee may call a telephonic meeting
                           on five days' written notice to the other members.

                  (d)               Formal annual meetings, which will coincide
                           with each fourth quarterly meeting, will be held by
                           the Steering Committee to review calculations of
                           Price Per Output Unit.

                  (e)               Quality, financial and standards issues 
                           will be addressed by a quality committee (the
                           "Quality Committee"), a finance committee (the
                           "Finance Committee"), and a standards committee (the
                           "Standards Committee"), respectively. The Quality
                           Committee will have the right to initiate audits and
                           analyses, and based on these ensure at all times an
                           appropriate quality of performance and will
                           recommend remedies or refer any areas of deficiency
                           to the Steering Committee. The Quality Committee
                           shall be composed of an equal number of
                           representative members from each party and HMR shall
                           designate one of its representative members as
                           Chairperson. The Finance Committee will conduct
                           financial analyses of Projects to provide the
                           Steering Committee with a reasonable basis for
                           judgment of budget utilization, cash flow and cash
                           neutrality and other financial information, as well
                           as performance and output measures. The Finance
                           Committee shall be composed of an equal number of
                           representative members from each party and Quintiles
                           shall designate one of its representative members as
                           Chairperson. The Standards Committee will determine
                           standards for all functional and infrastructure
                           areas and ensure compliance therewith. The Standards
                           Committee shall be



                                      33

                           composed of an equal number of representative
                           members of each party and co-chaired by a
                           representative member from each party.

                  (f)               There will be a Supervisory Committee 
                           composed of an equal number of representative
                           members of each company and co-chaired by a
                           representative member from each company
                           ("Supervisory Committee"). The Supervisory Committee
                           shall consider disputes and other matters related to
                           the relationship between HMR and Quintiles and shall
                           meet at least annually to explore additional
                           opportunities for Quintiles and HMR to collaborate
                           on additional business ventures.

                  (g)               Each party's representative members on any
                           committee shall be entitled to one vote in total. No
                           Chairperson of any of the above committees shall
                           have a second, casting or deciding vote. Actions of
                           each committee shall require a unanimous vote. Each
                           of the Finance, Quality and Standards Committees
                           shall make recommendations to the Steering Committee
                           and shall not have separate decision-making
                           authority except as specifically provided herein.
                           Disputes shall be resolved in accordance with the
                           provisions of Article 13. Actions of each committee
                           will be documented in meeting minutes signed by a
                           member from each of HMR and Quintiles.

         3.10     FACILITY COMMITMENT FEE

         In addition to the payment of Guaranteed Revenue and other obligations
hereunder, HMR shall pay to Quintiles a $* million facility commitment fee in
consideration for Quintiles



                                      34
<PAGE>   40
reserving sufficient capacity within the Facility to retrain staff, develop
standard operating procedures and make other changes to operate as a contract
research organization to meet HMR's requirements for Research Services during
the Initial Period. The fee shall be paid by wire transfer of immediately
available funds to Quintiles at the Closing. The facility commitment fee shall
not be refundable or repayable to HMR or any of its Affiliates in any
circumstances whatsoever.

         3.11     YEAR 2000 PROVISION.

         If, after the Closing, Quintiles continues to implement the Drug
Innovation & Approval portion of HMR's Year 2000 Program (as defined in
paragraph 11 of Schedule 4.2) in materially the same manner, and applying
materially the same level of resources, as HMR had planned for Drug Innovation
& Approval in 1999, (i) Quintiles will be excused from performance of any
obligation for Research Services contemplated under the Agreement, or any other
services contemplated under a Letter Agreement, but only to the extent such
performance is adversely affected, directly or indirectly, by the failure of
any Asset, system or computer software application to function properly due to
a Year 2000 Problem (as defined in paragraph 11 of Schedule 4.2), attributable
specifically to such Asset, system or computer software application Quintiles
acquires or obtains use of pursuant to this Agreement or any Transaction
Document, and (ii) HMR shall not be relieved from its obligations to make
payments of Guaranteed Revenue or otherwise be entitled to a refund or credit
of payments corresponding to the affected Research Services (including but not
limited to Guaranteed Revenue).

         In any such event, Quintiles shall use its best efforts to (i)
mitigate its potential damages; (ii) minimize the impact of the Year 2000
Problem on Projects, (iii) address Project delays on a priority basis over
non-Project work being performed at the Facility, and (iv) remediate the Year



                                      35
<PAGE>   41


2000 Problem. The Steering Committee may, if possible without negative impact
on any Project, adjust the timelines for deliverables for such Project in an
equitable manner (provided that, with respect to Projects involving Reserved
Capacity, periods in which Research Services cannot be performed based upon a
Year 2000 Problem shall be treated as if HMR failed to utilize the Reserved
Capacity). The condition that Quintiles "continues to implement the DI&A
portion of HMR's Year 2000 Program in a reasonable manner" shall be deemed
satisfied to the extent HMR fails to support Quintiles' reasonable requests for
HMR's support in implementing the DI&A portion of HMR's Year 2000 Program.

         Notwithstanding anything to the contrary, no Year 2000 Problem
attributable to an Asset or to any software application Quintiles obtains from
HMR shall constitute a breach by Quintiles of, or otherwise form a basis for
HMR terminating, this Agreement, any Letter Agreement or any other Transaction
Document.

Assumed Contracts; or (iii) Quintiles' use or lease of or ownership of the
Assets and operation of the Facility including, but not limited to, Quintiles'
use or disclosure of the HMR Licensed Technology in a manner inconsistent with

         4.4      LIMITATIONS ON INDEMNITY

                           Article 4 above shall be the parties' sole and
                           exclusive remedy for failure or breach by either
                           party of any warranty made under this Agreement or a
                           Schedule attached hereto or any other claim for

                           obligation in respect of a breach of any of the
                           warranties except as provided in prior provisions of
                           Article 4 above.

                  (b)      Except for those indemnification obligations set

                           circumstances giving rise to such claim or potential
                           claim) within three (3) years of the date of Closing
                           except that with respect to the warranties set forth
                           in section 7(n) of the Real Estate Sale Agreement
                           and Section 6.1(b) below, such notice shall be given

                  (c)      HMR shall not be liable under the HMR General
                           Warranties, under any other claim for Damages under
                           Section 4.2 above or under corresponding provisions
                           of the Transaction Documents unless its aggregate
                           liability for claims (including those arising
                           previously whether giving rise to payment or not
                           pursuant to this Article 4.4) hereunder or

                           or any other claim for Damages under prior
                           provisions of Article 4 above: 

                           (i)      to the extent that such liability would not
                                    have arisen but for any change of law
                                    occurring after the date of Closing;

                           (ii)     in respect of any matter in relation to

                                    shall, after the date of Closing, expressly
                                    have waived in writing its rights; or

                           (iii)    to the extent that such liability would not
                                    have arisen but for the negligence or other
                                    willful act or omission of the other party
                                    occurring after the date of Closing.

                  (e)      Neither party shall be liable under the warranties

                           special, indirect or consequential damages
                           including, but not limited to, loss of profits or
                           revenue.

                           respect of the warranties or any other claim for
                           Damages under prior provisions of Article 4 above.

                  (g)               In the event that either party has made a 
                           payment pursuant to a claim under the warranties or
                           any other claim for Damages under prior provisions
                           of Article 4 above and the other party shall receive
                           a reimbursement in respect of the matter in respect
                           of which such claim was made, that party shall
                           forthwith repay to the other party an equal sum to
                           the amount of such refund or, if lower, a sum equal
                           to the amount paid by that party pursuant to the
                           claim. Each party shall take all reasonable steps to
                           obtain payment of any such refunds.

         4.5      HMR'S RESPONSIBILITY AND INDEMNITY RE: TRANSFERRING EMPLOYEES

         HMR shall discharge all wages and salaries and other remuneration of

                  (c)      all Damages incurred by Quintiles as a result of any

                           so to discharge;

                  (b)               all Damages incurred by HMR as a result of

                  (c)               all Damages resulting from any claim made

         4.7      PROCEDURES RE: GENERAL AND EMPLOYEE INDEMNITIES

                  (a)      The party seeking indemnification under this Article
                           4 shall notify the indemnifying party within thirty
                           days of its receipt of knowledge of the existence of
                           any claim, demand or other matters including, but
                           not limited to, any claim under the warranties set
                           forth in Article 6 below or Schedule 4.2 that may
                           affect the indemnifying party's obligation of
                           indemnity hereunder. Although the indemnifying party
                           shall have the right to assume the defense in such
                           case, the indemnified party shall have the right to
                           employ its own legal agents in any such case, but in
                           such event, the fees and expenses of such legal
                           agents shall be at the indemnified party's expense.
                           The indemnified party shall be kept fully informed
                           of such action, claim or proceeding at all stages
                           thereof whether or not it is represented.

                  (b)      The indemnified party shall make available to the
                           indemnifying party and its legal advisers
                           free-of-charge all relevant books, records,
                           documents and other information and personnel of the
                           indemnified party relating to such proceedings or
                           litigation and the parties hereto agree to render to
                           each other such assistance as they may reasonably
                           require of each other in order



                                      42
<PAGE>   48

                           to ensure the proper and adequate defense of any
                           such action, claim or proceedings.

                  (c)      The indemnified party shall not make any formal
                           admission of liability nor make any settlement of
                           any claim without the written consent of the
                           indemnifying party and if such admission of
                           liability is made by the indemnified party without
                           the prior written consent of the indemnifying party,
                           the indemnified party shall be deemed to have
                           compromised and waived any claim for indemnification
                           hereunder.

         HMR hereby covenants and agrees to release, indemnify, protect, defend
and hold harmless Quintiles and its Affiliates, officers, directors,
shareholders, agents, employees, representatives, successors, and assigns from
and against any and all Damages suffered, incurred by or asserted against
Quintiles relating to, arising out of, or connected with, any event or
condition which was created or caused prior to or including the Environmental
Report Date (except as otherwise indicated in Section 4.9), or which was
created or caused by HMR after the Environmental Report Date, and which relates
to:

                           (i)      any Release, threatened Release or disposal
                                    of Hazardous Materials at, upon, under, or
                                    from the Facility;

                           (ii)     the operation or violation of Environmental
                                    Laws or Environmental Permits at the
                                    Facility;

                           (iii)    any Environmental Claim in connection with
                                    the Facility or HMR's operations at the
                                    Facility;

                           (iv)     any Environmental Claim in connection with
                                    any disposal by HMR of Hazardous Materials
                                    from the Facility at any off-site facility;
                                    or

                           (v)      any breach by HMR of any covenant,
                                    representation or warranty of HMR contained
                                    in this Agreement and giving rise to an
                                    Environmental Claim.

         The foregoing indemnity in subsections (i) through (iv) is not subject
to or in any way limited or reduced by the representations, warranties, or
agreements of HMR set forth in this Agreement, or any limitations thereof.



                                      44
<PAGE>   50

         HMR acknowledges that the environmental due diligence of the Facility
may not be satisfactorily completed by the date of Closing, though it is
expected to be completed by January 31, 1999. HMR agrees that: (i) the date
both the due diligence is completed and a final report thereof is satisfactory
to both parties (the "Environmental Report Date") and (ii) the substance of
such final report, shall serve as information available for the allocation of
environmental responsibility.

         4.9      QUINTILES' INDEMNITY RE: ENVIRONMENTAL CLAIMS

         Quintiles hereby covenants and agrees to release, indemnify, protect,
defend and hold harmless HMR and its Affiliates, officers, directors,
shareholders, agents, employees, representatives, successors, and assigns from
and against any and all Damages suffered, incurred by or asserted against HMR
relating to, arising out of, or connected with, directly or indirectly, any
event or condition which is created or caused by Quintiles after the
Environmental Report Date, or after the date of Closing and prior to the
Environmental Report Date and which clearly results from the activities of
Quintiles prior to the Environmental Report Date that are inconsistent with the
practices of HMR prior to the date of Closing, with, in any event, the
exception of those events or conditions giving rise to HMR's indemnity
obligations in Section 4.8 above, and which relates to:

                           (i)      any Release, threatened Release or disposal
                                    of Hazardous Materials at, upon, under, or
                                    from the Facility;

                           (ii)     the operation or violation of Environmental
                                    Laws or Environmental Permits at the
                                    Facility;

                           (iii)    any Environmental Claim in connection with
                                    the Facility or Quintiles' operations at
                                    the Facility;



                                      45
<PAGE>   51

                           (iv)     any Environmental Claim in connection with
                                    any disposal by Quintiles of Hazardous
                                    Materials at any off-site facility; or
                           
                           (v)      any breach by Quintiles of any
                                    covenant, representation or warranty of
                                    Quintiles contained in this Agreement and
                                    giving rise to an Environmental Claim.

         The foregoing indemnity in subsections (i) through (iv) is not subject
to or in any way limited or reduced by the representations, warranties, or
agreements of Quintiles set forth in this Agreement.

         Quintiles acknowledges that the environmental due diligence of the
Facility may not be satisfactorily completed by the date of Closing, though it
is expected to be completed by January 31, 1999. Quintiles agrees that: (i) the
Environmental Report Date and (ii) the substance of such final report shall
serve as information available for the allocation of environmental
responsibility.

         4.10     NUCLEAR MATERIALS LICENSE AND "RAD-BUILDING"

         Prior to the completion of the transfer of HMR's Nuclear Materials
License to Quintiles, HMR shall, at its sole expense (i) perform a radiation
contamination survey of HMR's existing radioactive waste storage facility (the
"Rad-Building") and any other area on the Facility where radioactive materials
have been stored, handled, or otherwise used or transported by HMR and (ii)
conduct any required decontamination of any area affected by radiation
contamination. At such time as Quintiles ceases permanently its use of the
Rad-Building, whether or not as a result of termination of its lease of the
Rad-Building (the "Rad-Building Lease"), Quintiles shall, at its sole expense
(i) perform a radiation contamination survey of the Rad-Building, (ii) conduct
any required decontamination of any area of the Rad-Building affected by
radiation contamination and (iii) decommission the Rad-Building; provided,
however, that, with respect to the foregoing



                                      46
<PAGE>   52

clause (iii), if, and only if, decommissioning of the Rad-Building is required
because HMR has exercised its right to terminate the Rad-Building Lease for the
purpose of relocating such storage facility to a replacement building, the cost
of decommissioning the Rad-Building shall be apportioned between HMR and
Quintiles based on the relative number of years each party used the
Rad-Building. At such time as (a) Quintiles' Nuclear Materials License expires,
or otherwise ceases to be in effect, or (b) Quintiles ceases permanently its
use of any area, other than the Rad-Building (whether in connection with a
permanent cessation of use of the Rad-Building or otherwise), where radioactive
materials have been stored, handled, or otherwise used or transported by
Quintiles, then Quintiles shall, at its sole expense, complete steps (i)
through (iii) above (without reference to the proviso set forth above in such
clause (iii)) for (x) in the case of clause (a) above, the Rad-Building and any
other area where radioactive materials have been stored, handled, or otherwise
used or transported by Quintiles or (y) in the case of clause (b) above, such
area where radioactive materials have been stored, handled, or otherwise used
or transported by Quintiles.

         Further, within 10 business days of the date of this Agreement, HMR
and Quintiles shall enter into a lease whereby HMR shall lease the Rad-Building
to Quintiles on the terms and conditions set forth in Schedule 4.10 to this
Section 4.10, and on such other terms and provisions as the parties shall
mutually agree.

5.       EMPLOYMENT AND BENEFITS OF TRANSFERRING EMPLOYEES

         5.1      QUINTILES' EMPLOYMENT OF TRANSFERRING EMPLOYEES

                  (a)               Attached hereto as Schedule 5.1(a) are 
                           forms of offer letters for the Transferring
                           Employees. Quintiles has provided to HMR a list of
                           the base salaries and positions to be offered to
                           each such Transferring



                                      47
<PAGE>   53

                           Employee. HMR has reviewed such forms of offer
                           letters and such list and found them to be
                           satisfactory. Quintiles shall make offers to the
                           Transferring Employees pursuant to the forms of
                           offer letters and consistent with the information on
                           such list. Notwithstanding anything to the contrary,
                           Quintiles shall have no responsibility for any
                           severance or other compensation obligation owed to
                           any of the Transferring Employees as a result of any
                           severance or other agreements or benefits offered
                           previously by HMR. Initially, Quintiles shall not
                           require Transferring Employees to transfer from
                           Kansas City to another Quintiles facility. For a
                           period of three years after the date of Closing and
                           so long as Quintiles is receiving the Guaranteed
                           Revenue, Quintiles will not terminate any Option
                           Recipient without a reasonable basis in conduct or
                           performance or without first obtaining the consent
                           of HMR, which consent shall not be unreasonably
                           withheld or delayed.

                  (b)               Attached as Schedule 5.1(b) is a list of 
                           those Transferring Employees who are nonimmigrant
                           aliens working, or scheduled to begin working, for
                           HMR at the Facility prior to Closing. After the date
                           of Closing, each of these Transferring Employees
                           shall remain employees of HMR until Quintiles has
                           obtained the approval of a petition for nonimmigrant
                           workers for such Transferring Employee from the
                           Immigration and Naturalization Service ("INS") to
                           employ such Transferring Employee. As to those
                           Transferring Employees listed on Schedule 5.1(b) who
                           have indicated a desire to become employees of



                                      48
<PAGE>   54

                           Quintiles, Quintiles shall use its best efforts to
                           obtain such approval as promptly as practicable.
                           Quintiles shall have the benefit, from and after the
                           date of Closing, of the services of such employees
                           indicating a desire to work for Quintiles.
                           Thereafter, each such Transferring Employee shall
                           become an employee of Quintiles. For purposes of
                           Sections 4.5, 4.6, 5.3(b) and 9.1(b)(ii) of this
                           Agreement, the term "date of Closing" with respect
                           to each of these employees shall mean the date that
                           Quintiles has obtained the INS approval described
                           above.

                  (c)               Each Transferring Employee who is on 
                           short-term disability leave or Family and Medical
                           Leave Act leave as of the Closing pursuant to the
                           otherwise applicable plans and policies of HMR shall
                           remain an employee of HMR until the date he or she
                           returns to work from leave. As of that date, each
                           such Transferring Employee who has accepted an offer
                           of employment from Quintiles shall then become an
                           employee of Quintiles. For purposes of Sections 4.5,
                           4.6, 5.3(b) and 9.1(b)(ii) of this Agreement, the

                           Transferring Employee becomes an employee of
                           Quintiles. HMR shall provide to Quintiles a list of
                           all such Transferring Employees within ten days of

benefits of Quintiles in which similarly situated employees of Quintiles'
United States operations are generally eligible to participate, provided that
nothing herein shall prevent Quintiles from amending or terminating any such
plan in accordance with its terms and applicable law. For purposes of
Quintiles' employee stock ownership plan, employee stock purchase plan and
vacation policy, Quintiles shall grant the Transferring Employees credit for
the number of years of service with which they are credited by HMR.

         5.3      APPORTIONMENTS

                  (a)               The Transferring Employees who have 
                           properly accrued unused vacation that they would
                           otherwise be entitled to carry over to 1999 had they
                           continued as employees of HMR, may each carry over
                           up to five days of such accrued unused vacation. On
                           the Closing, HMR shall pay to Quintiles the value of
                           such accrued unused vacation, and Quintiles shall
                           permit each Transferring Employee to use such
                           accrued unused vacation day(s) during 1999;
                           provided, however, that as promptly as practicable
                           after the date of Closing, Quintiles shall reimburse
                           HMR for the amount of such accrued payment that
                           relates to Transferring Employees who do not become
                           employees of Quintiles.

                  (b)               Except as provided in Section 5.3(a) above,
                           all payments due in respect of any wages, salaries
                           or other remuneration with respect to the
                           Transferring Employees up to and including the date
                           of Closing shall be borne by HMR and, except as set
                           forth in Section 9.2(c), all payments due in respect
                           of any wages, salaries or other remuneration with
                           respect to

                           after the date of Closing shall be borne by
                           Quintiles.

         5.4      KEY TRANSFERRING EMPLOYEE RETENTION

         Quintiles shall offer a key employee retention plan, available to the
key Transferring Employees identified by HMR on Schedule 5.4(a) (the "Option
Recipients"), pursuant to the terms of an option agreement attached hereto as
Schedule 5.4(b). This option agreement is intended by the parties to be an
inducement to such key Transferring Employees to become Quintiles employees.
The aggregate value of the options to be granted under this Section 5.4, based
on a Black Scholes valuation, shall be $* million.

         5.5      RAIDING OF OTHER PARTY'S EMPLOYEES

         Both HMR and Quintiles agree that during the Initial Period neither
will recruit nor hire, directly or indirectly, any of the Kansas City-based
employees of the other, regardless of the position of the employee, except upon
mutual agreement by Quintiles and HMR or if employment of the former employee
terminated more than one year prior to the date of such recruitment or initial
hiring contact. HMR and Quintiles agree that, notwithstanding the foregoing,
Quintiles may make offers of employment to the employees listed on Schedule
5.5(a) at any time more than six (6) months after Closing. Except as to those
Transferring Employees listed on Schedule 5.5(b), neither HMR nor any Affiliate
has made an offer to employ any Transferring Employee outside of its Kansas
City Drug Innovation & Approval unit.

8.       TERMINATION 

         8.1 QUINTILES' RIGHT TO TERMINATE DURING THE INITIAL PERIOD

         Quintiles shall have the right to terminate this Agreement and the
Transaction Documents prior to the completion of the Initial Period and upon
written notice at any time in the event that (i) HMR is in breach of a monthly
payment obligation of Guaranteed Revenue under Article 3 above, provided: (A)
such breach has continued for a period of ten (10) business days after



                                      60
<PAGE>   66

written notice thereof, (B) such termination shall be effective only upon
further written notice to HMR, and (c) such payment obligation is not then the
subject of a dispute that HMR is actively pursuing in good faith through the
dispute resolution process described in this Agreement; or (ii) HMR terminates
the Lease (except as permitted pursuant to the terms of the Lease upon the
occurrence of a default by Quintiles thereunder); or (iii) HMR takes or omits
to take any action that prevents Quintiles' ability to provide to HMR Research
Services in accordance with this Agreement having associated revenue of $25
million. If Quintiles exercises such right to terminate this Agreement,
Quintiles shall have the right to (x) require HMR to purchase the Purchased
Property and the Facility (if it has been purchased by Quintiles) at the
purchase price therefor of $93,000,000 in the aggregate less any depreciation
taken by Quintiles with respect thereto, and to reacquire the Leased Property,
and (y) require HMR to assume any contracts related to the Assets, which shall
not include any contracts entered into by Quintiles with third parties to
provide or receive Research Services. Subject to Section 8.4, if Quintiles
exercises its right to terminate this Agreement, it must terminate all
Transaction Documents. The assignment and assumption to be used in the event of
transferring Leased Property back to HMR shall be in the same form as the
Assignment and Assumption Agreement.

         8.2      HMR'S RIGHT TO TERMINATE DURING THE INITIAL PERIOD

         HMR shall have the right to terminate this Agreement and the
Transaction Documents immediately upon written notice if: (i) there is a
failure to close under the Real Estate Sale Agreement due to a material breach
thereunder by Quintiles, which material breach persists after any notice and
cure period provided for therein, and Quintiles has not exercised its option to
convert the Lease to the Long Term Lease as defined in the Real Estate Sale
Agreement; or (ii) there is a Persistent Material Failure on the part of
Quintiles to fulfill its obligations to provide 



                                      61
<PAGE>   67

Research Services to HMR as referred to in Section 3.1 above. For the purpose
of this Section, Persistent Material Failure shall mean material breach of the
performance obligations imposed on Quintiles in terms of the Letter Agreements
where Quintiles, having been given a reasonable opportunity to remedy such
breach, has failed to do so such that in any one year during the Initial Period
HMR, without breach of contract and for cause, terminates four or more Letter
Agreements having an aggregate value of not less than $25 million. If HMR
exercises its right to terminate this Agreement, it must terminate all
Transaction Documents.

         8.3      TERMINATION FOR INSOLVENCY

         Either party shall have the right to terminate this Agreement and the
Transaction Documents immediately upon written notice at any time during the
Initial Period in the event that the other is declared insolvent by a court of
competent jurisdiction or shall be the subject of any reorganization (other
than a corporate reorganization and not arising out of any insolvency) or
winding up, receivership or dissolution or any proceeding similar to one or
more of the above. If either party exercises its right to terminate this
Agreement, it must terminate all Transaction Documents.

         8.4      QUINTILES' OPTION TO CONTINUE TO LEASE

         Notwithstanding other provisions of this Article 8, in the event of
termination of this Agreement by Quintiles under Section 8.1 above, or by HMR
under Section 8.2 above, during the Initial Period but prior to the time
Quintiles has either purchased the Facility from HMR or exercised its option to
convert the Lease to the Long Term Lease as defined in the Real Estate Sale
Agreement, Quintiles shall be entitled, at its option: (i) to continue to lease
the Facility on the terms set out in the Lease and the other Leased Property on
the terms and conditions contained in the Assignment and Assumption Agreement,
in each case until December 31, 2003; 



                                      62
<PAGE>   68

and (ii) to continue to license such HMR Licensed Technology pursuant to the
Intellectual Property License as is necessary or appropriate to use, occupy or
perform, respectively, the Purchased Property, the Facility, and continuing
Letter Agreements; provided, however, that if Quintiles so elects to continue
the Lease, it shall remain obligated under the Real Estate Sale Agreement to
purchase the Facility pursuant to the terms and conditions of the Real Estate
Sale Agreement. In the event of termination by Quintiles under Section 8.1
above, or by HMR under Section 8.2 above, during the Initial Period and after
Quintiles has either purchased the Facility from HMR or entered into a Long
Term Lease as defined in the Real Estate Sale Agreement, Quintiles shall be
entitled, at its option: (i) to continue to lease the Leased Property on the
terms and conditions contained in the Assignment and Assumption Agreement until
December 31, 2003, and (ii) to continue to license such HMR Licensed Technology
pursuant to the Intellectual Property License as is necessary or appropriate to
use, occupy or perform, respectively, the Purchased Property, the Facility, and
continuing Letter Agreements.

         8.5      CONSEQUENCES OF TERMINATION

         Upon termination under this Article 8 for whatever reason, both HMR
and Quintiles shall, subject, to Section 8.4 above, be relieved of their
obligations then outstanding under this Agreement save for:

                  (a)      Quintiles' obligations to the Transferring Employees
                           under Section 4.6 above; 

                  (b)      Quintiles' indemnity with respect to Assumed 
                           Contracts under Section 4.2 above;

                  (c)      both parties' indemnity obligations pursuant to 
                           Article 4 above; 



                                      63
<PAGE>   69

                  (d)      both parties' obligations of confidentiality, 
                           non-use and non-disclosure under Article 11 below;

                  (e)      the indemnity obligations under Section 
                           12.1 below; and

                  (f)      the right of the parties to be paid all 
                           sums due to them as of the date of termination and
                           to enforce any other rights or remedies arising out
                           of obligations which existed under this Agreement
                           prior to the termination, including, but not limited
                           to, any damages arising after termination out of a
                           breach occurring prior to termination.

         Notwithstanding anything to the contrary in this Article 8, in the
event that Quintiles terminates this Agreement but remains in possession of the
Facility, the Operation, Maintenance and Utility Service Agreement and the
separate Services Agreement shall remain in full force and effect.

         8.6      RIGHTS OF HMR AND QUINTILES, AND EXCLUSION OF CONSEQUENTIAL 
                  LOSS

         The provisions of this Article 8 are without prejudice to the rights
of either party to seek any other remedy at law or at equity to which it may be
entitled other than termination. Notwithstanding anything to the contrary,
neither party shall be liable for consequential damages, including, but not
limited to loss of profits, or loss of revenue arising from a breach of this
Agreement provided that amounts payable under the express terms of this
Agreement or any Letter Agreement shall not be considered consequential damages
and the payment of such revenues shall be enforceable at law or in equity.

         9.1      PRE-CLOSING COVENANTS

                  (a)      Prior to the date of Closing, HMR will permit 
                           Quintiles and its representatives and agents to have
                           access for purposes reasonably related to the Assets
                           and to its documents, books and records related
                           thereto and to make copies during normal business
                           hours of such financial and operating data and other
                           information with respect to the Assets, as Quintiles
                           or any of its representatives or agents shall
                           reasonably request. In addition, HMR shall cause
                           appropriate representatives to be available to
                           Quintiles, its representatives and agents at such
                           times, and from time to time, as Quintiles may
                           reasonably request in connection with the
                           consummation of this Agreement and the transactions
                           contemplated thereby. HMR will cause to be delivered

                           books and records relating to the Assets as may be
                           reasonably requested by Quintiles or any of its
                           representatives or agents.

                  (b)      On and prior to the date of Closing, except as 
                           otherwise required by this Agreement, HMR will
                           conduct its operations carried on at the Facility
                           only in the ordinary course and will use its
                           commercially reasonable efforts to maintain the
                           relationships of HMR with distributors, suppliers,
                           vendors, employees, agents, governmental authorities
                           and others. Without limiting the generality of the
                           foregoing, on and prior to the date of Closing, HMR
                           will not, except as contemplated by this Agreement,

                                    any action that will cause any of the
                                    representations or warranties in this
                                    Agreement, including Schedule 4.2 hereto,
                                    to become untrue.

                  (c)      On and prior to the date of Closing the parties

                           whether Environmental Permits will be transferred to
                           Quintiles or retained by HMR, whether separate
                           Environmental Permits will be obtained by Quintiles
                           or HMR, or whether Environmental Permits will be
                           shared. Quintiles will initiate the Transfer of
                           HMR's existing Environmental Permits that will be
                           transferred to Quintiles that relate to transferred
                           Assets or the obtaining of separate Environmental
                           Permits for Quintiles. HMR agrees to assist
                           Quintiles in the Transfer of Environmental Permits
                           that

                           will be transferred to Quintiles that relate to
                           transferred Assets or the obtaining of separate
                           Environmental Permits for Quintiles. HMR will
                           initiate obtaining separate Environmental Permits
                           for HMR. Quintiles agrees to cooperate with HMR for
                           the obtaining of separate Environmental Permits for
                           HMR. HMR and Quintiles agree to cooperate with each
                           other to segregate between HMR and Quintiles any
                           Environmental Permits that relate both to HMR's
                           operations or property and to transferred Assets.
                           HMR and Quintiles agree to proceed with a joint
                           permit where Environmental Permits can not be
                           reasonably transferred, aggregated or otherwise
                           obtained. HMR shall make available for Quintiles'
                           review and copying all environmental reports
                           prepared by or for HMR relating to the Facility and
                           operations at the Facility and all Environmental
                           Permits, relating to the Facility and operations at
                           the Facility.

                  (d)      Prior to the date of Closing, the parties shall
                           negotiate in good faith to finalize the Transaction
                           Documents not finalized as of the date of this
                           Agreement.

                  (e)      Prior to the date of Closing, Quintiles will not,
                           except as contemplated by this Agreement, without
                           the prior written consent of HMR, take any action or
                           omit to take any action that will cause any of the
                           representations or warranties in this Agreement,
                           including Schedule 4.3 hereto, to become untrue.

                  (f)      On and before the date of Closing, Quintiles will
                           use commercially reasonable efforts to obtain and
                           deliver the environmental due diligence report to
                           HMR on a timely basis.

         9.2      POST-CLOSING COVENANTS

                  (a)      At any time and from time to time after the Closing,
                           the parties agree to cooperate with each other to
                           prepare, execute and deliver such other documents,
                           instruments of transfer, assignment, files, books
                           and records and do all such further acts and things
                           as may be reasonably required to carry out the
                           transactions contemplated hereunder.

                  (b)      Except as would not be allowed by applicable
                           Environmental Laws, Quintiles and HMR agree to
                           Transfer Environmental Permits or to obtain separate
                           Environmental Permits and provide equivalent
                           environmental services as follows: 

                           (i)      Prior to the time in which Transfer or 
                                    obtaining of separate Environmental Permits
                                    is completed, HMR's Environmental Permits
                                    shall remain in full force and effect with
                                    respect to those Assets covered by the
                                    terms of any Environmental Permit. During
                                    the Interim Period, Quintiles will operate
                                    those Assets covered by any Environmental
                                    Permit as agent of HMR;

                           (ii)     During the Interim Period, Quintiles hereby
                                    covenants and agrees to release, indemnify,
                                    protect, defend and hold harmless HMR and
                                    its Affiliates, officers, directors,
                                    shareholders, agents, employees,
                                    representatives, successors and assigns
                                    from and against any and all Damages
                                    suffered, incurred by or asserted against
                                    them relating to, arising out of, or
                                    connected with, directly or indirectly, any
                                    event or condition created or caused by
                                    Quintiles' operation of

                                    permitted equipment after the Closing under
                                    any Environmental Permit of HMR, including,
                                    without limitation, under any agency
                                    relationship;

                           (iii)    In the event that any of HMR's 
                                    Environmental Permits cannot be Transferred
                                    to Quintiles, or Quintiles cannot
                                    otherwise, without incurring significant
                                    unnecessary expense, obtain a necessary
                                    separate Environmental Permit, HMR and
                                    Quintiles shall enter into a joint
                                    operating agreement to continue operations
                                    at the Facility and provide uninterrupted
                                    use of the Assets subject to the
                                    Environmental Permit. Under the terms of
                                    such joint operating agreement, the parties
                                    shall allocate direct costs of operation
                                    and liabilities based on total flow rate
                                    and chemical and physical properties or
                                    constituencies of treated waste streams
                                    contributed by each party. Further, with
                                    respect to any joint operating agreement
                                    each party shall be solely responsible for
                                    any and all fines, penalties, and other
                                    costs arising out of or due to such party's
                                    activities; provided, however, that to the
                                    extent the origin, as among the parties, of
                                    the activity giving rise to such fines,
                                    penalties, or costs cannot be determined,
                                    the parties shall equitably allocate among
                                    them such fines, penalties, and costs,
                                    based on all available information
                                    regarding the volume, composition, and
                                    nature of activities of each party that
                                    contributed to the assessment of such
                                    fines, penalties, and other costs.

                  (c)      Cash bonuses for Transferring Employees who have
                           earned the right to receive payment of a bonus under
                           HMR's 1998 Bonus Plan shall be paid to such
                           Transferring Employees by HMR no later than March
                           31, 1999.

                  (d)      Quintiles shall continue all projects on which the
                           Transferring Employees are currently working in
                           accordance with the terms of the Master Services
                           Agreement and related Letter Agreements; provided,
                           however, that until completion of a Letter Agreement
                           for any particular project, Quintiles shall, to the
                           extent commercially reasonable, continue to perform
                           such project on current timelines and budgets
                           subject to review by the Steering Committee. Work
                           performed by Quintiles on all such projects shall
                           count toward the Guaranteed Revenue.

                  (e)      The parties shall take commercially reasonable steps
                           to separate the facilities. Specifically, the
                           parties shall as expeditiously as possible relocate
                           Quintiles' employees from "Building H" into
                           "Building F" and HMR employees from "Building F"
                           into "Building H". The parties shall share equally
                           the costs associated with separating the Facility
                           and its use from the remaining portion of the
                           business park owned by, and the operation of, HMR
                           including, but not limited to, the costs of
                           re-engineering the security system, separating the
                           physical space, separating the computer facilities
                           and the computer equipment, transferring permits,
                           creating the requisite ownership interests in the
                           real property, personnel and personal property
                           relocations and all similar costs. The parties shall
                           consult with each other prior to taking steps to
                           effectuate such separation. 



                                      71
<PAGE>   77

                           Notwithstanding the foregoing, the costs of moving
                           certain lab equipment from "Building D" into the
                           Facility shall be borne by Quintiles.

                  (f)               Immediately after the Closing, the parties
                           shall meet to determine whether an adequate number
                           and level of Transferring Employees have agreed to
                           become employees of Quintiles such that Quintiles
                           can provide the Research Services at substantially
                           the same level provided by the Transferring
                           Employees in 1998. If the parties conclude that an
                           inadequate number or level of Transferring Employees
                           have become employees of Quintiles, the parties
                           shall, within 30 days after Closing, agree to a
                           mutually acceptable amendment to the terms hereof,
                           which shall include, for a reasonable period of time
                           until Quintiles hires necessary replacements, a
                           reduction in the obligation of Quintiles to provide
                           the Research Services in proportion to the shortfall
                           in necessary capacity, a reduction of the Guaranteed
                           Revenue payable by HMR equal to the direct cost
                           savings attributable in compensation expense
                           attributable to the shortfall in necessary capacity
                           and, to the extent reasonably necessary, a delay in
                           the offering of Research Services significantly
                           impaired by the inadequate number or level of
                           Transferring Employees who have joined Quintiles;
                           provided that Quintiles shall exercise commercially
                           reasonable efforts to hire the necessary staff as
                           soon as reasonably possible. If the parties cannot
                           agree on all issues pertinent to this Section
                           9.2(f), and neither the Steering Committee nor the
                           Supervisory Committee can resolve the matter, then
                           the adjustments necessary to make each of 



                                      72
<PAGE>   78

                           Quintiles and HMR whole in light of the shortfall of
                           necessary capacity shall be determined by
                           arbitration pursuant to Article 13, it being
                           understood and agreed that Quintiles shall not be
                           required to suffer economic harm, and HMR shall not
                           be required to suffer an unreasonable delay in
                           performance as a result of closing with an
                           inadequate number and level of Transferring
                           Employees.

                  (g)               After the Closing: (i) HMR shall pay as 
                           and when due all amounts due to third parties under
                           Assumed Contracts for all periods on or prior to the
                           date of Closing; and (ii) Quintiles shall pay as and
                           when due all amounts due to third parties under
                           Assumed Contracts for all periods subsequent to the
                           date of Closing.

                  (h)               Quintiles shall not, and shall cause its
                           Affiliates not to, seek an amendment to the TIF
                           Agreement or Plan as described in Section 2.5(d).

                  (i)               Until the removal and disposal of HMR's

                           in the first instance, to the Steering Committee
                           and, failing resolution at the next available
                           meeting of the Steering Committee or in the event
                           that the matter is of such urgency that either

                           either party may bring the matter before the
                           Supervisory Committee, and a special meeting of that

                                      75
<PAGE>   81

                  (b)      In the event that the matter in dispute is not
                           resolved by the unanimous resolution of the Steering
                           Committee or the Supervisory Committee, either party
                           may, upon notice to the other party, refer such
                           matter for arbitration in Kansas City, Missouri, in
                           accordance with the rules of commercial arbitration
                           of the American Arbitration Association; provided,
                           however such referral must be made after fifteen
                           (15) and before sixty (60) days following the date
                           of the decision rendered by the Supervisory
                           Committee.

                  (c)      In connection with any arbitration, Quintiles shall
                           appoint one arbitrator and HMR shall appoint one
                           arbitrator. The arbitrators appointed by Quintiles
                           and HMR respectively shall be independent and shall
                           have expertise in the matter in dispute between the
                           parties. A third arbitrator shall be appointed by
                           the arbitrators appointed by Quintiles and HMR
                           respectively.

                  (d)      Each of Quintiles and HMR undertakes to present its
                           case to the arbitrators in the shortest practicable
                           time and to use its best efforts to ensure that the
                           arbitrators make an award in respect of the matter
                           in dispute within thirty (30) days of the final day
                           upon which their respective submissions are made.

14.      TAX ALLOCATION

         14.1     SALES TAX. Quintiles shall provide to HMR at Closing a 
Sales/Use Tax Exemption Certificate certifying to HMR the good faith belief of
Quintiles that no sales or use tax is due as a result of the sale, lease or
other transfer of personal property by HMR to Quintiles pursuant to this
Agreement. To confirm the validity of the position taken in such certificate
and



                                      76
<PAGE>   82

at Quintiles' sole cost and expense, Quintiles and HMR agree to use their
respective best efforts and work together to file expeditiously after the
Closing a joint private letter ruling request with the Missouri Department of
Revenue pursuant to Regulation Section 12 CSR 10-1.202. Quintiles and HMR agree
to be bound by the private letter ruling that the Missouri Department of
Revenue issues pursuant to such request.

         14.2     INDEMNIFICATION OF HMR BY QUINTILES. Quintiles agrees to hold
harmless, indemnify and defend HMR, and its Affiliates, directors, officers,
employees and agents, from and against any and all demands, causes of action,
proceedings, losses, damages, debts, expenses, liabilities, fines, penalties,
deficiencies, judgments or costs (including reasonable attorneys' fees)
("Claims") at any time and from time to time asserted against or incurred by
HMR to the extent based on, or resulting or arising from, the alleged failure
by HMR to pay any amount of state or local sales or use tax (or any interest or
penalty with respect to state or local sales tax) on the personal property
sold, leased or otherwise transferred pursuant to this Agreement.

         14.3     INDEMNIFICATION PROCEDURE. In the event HMR seeks 
indemnification under this Section 14:

         (a)               HMR shall give Quintiles prompt written notice of 
                  the Claim asserted against or imposed upon or incurred by HMR
                  (which notice shall in any event be given within thirty days
                  of the receipt by HMR of knowledge of the existence of any
                  Claim and shall set forth the basis of the Claim and provide
                  evidence to Quintiles that the Claim is covered by the
                  indemnification provided in Section 14.2), and Quintiles
                  shall have the right to undertake the defense thereof by
                  representatives of its own choosing, provided that Quintiles
                  diligently conducts the defense of such



                                      77
<PAGE>   83

                  Claim; provided, however, that HMR shall have the right, at
                  its expense, to retain its own counsel as to such Claim.



                                      78
<PAGE>   84

         (b)               In the event that Quintiles, within twenty (20)
                  calendar days after receipt of notice of the Claim, fails or
                  refuses to undertake the defense of such Claim, HMR will
                  (upon further written notice to Quintiles) have the right to
                  undertake the defense, compromise or settlement of such Claim
                  on behalf of and for the account and risk of Quintiles,
                  subject to the right of Quintiles to assume the defense of
                  such Claim at any time prior to the settlement, compromise or
                  final determination thereof. If HMR undertakes the defense,
                  compromise or settlement of any such Claim pursuant to this
                  Section 14.3(b), Quintiles shall promptly reimburse HMR for
                  any reasonable legal fees and expenses incurred in connection
                  therewith within five (5) business days of receipt of notice
                  seeking such reimbursement.

         (c)               In the event the Missouri Department of Revenue
                  conducts an audit of HMR's sales and/or use tax returns for
                  the HMR tax period during which this Agreement becomes
                  effective, HMR shall give Quintiles prompt written notice of
                  any written inquiry arising from that audit that could
                  reasonably be expected to result in a Claim under this
                  Agreement, shall keep Quintiles informed of any changes in
                  the status of such inquiry, and shall not compromise or
                  settle such potential Claim without Quintiles' written
                  consent.

         (d)               Notwithstanding anything to the contrary contained 
                  herein, if there is a reasonable probability that any Claim
                  may materially and adversely affect HMR other than as a
                  result of money damages or other 



                                      79
<PAGE>   85

                  money payments, HMR shall have the right to defend,
                  compromise or settle such Claim; provided, however, in such
                  event, if HMR shall compromise or settle such Claim without
                  the approval of Quintiles, Quintiles shall not be bound by
                  such compromise or settlement and shall have no
                  indemnification obligation as to such Claim. Quintiles shall
                  not, without HMR's written consent, settle or compromise any
                  Claim or consent to entry of any judgment as to a Claim that
                  does not include, as an unconditional term thereof, the
                  release of HMR by the claimant or the plaintiff from all
                  liability in respect of such Claim.

15.      MISCELLANEOUS

         15.1     ENTIRE AGREEMENT

         This Agreement, together with the Transaction Documents and the
Confidential Disclosure Agreement set forth the entire agreement and

written or oral, between the parties with respect to the subject matter hereof.
None of the terms of this Agreement shall be amended or modified except in
writing signed by the parties hereto.

         15.2     ASSIGNMENT

         Either party shall be entitled, at its sole discretion, to assign any
of its rights or obligations under this Agreement to any Affiliate or
Affiliates. No such assignment shall release the assigning party from any such
assigned obligations hereunder as a result of such assignment unless or until
such obligations are performed by its Affiliates. Save to the extent provided
in the



                                      80
<PAGE>   86

foregoing sentence, neither party may assign any right or obligation hereunder
without the written consent of the other party, except if such assignment
arises under a transaction in which the assigning party is selling its entire
business or a line of business or operations to which this Agreement relates,
or that party is being acquired or merging, in each case to, by or with a third
party that is not a direct competitor of the nonassigning party. This Agreement
shall be binding upon and inure to the benefit of the parties' respective
predecessors and permitted assigns. Any attempted assignment in violation of
this provision shall be void and of no effect.

         15.3     INVALIDITY

         If and solely to the extent that any provision of this Agreement shall
be invalid or unenforceable, or shall render this entire Agreement to be
unenforceable or invalid, such offending provision shall be of no effect and
shall not affect the validity of the remainder of this Agreement or any of its
provisions; provided, however, the parties shall use their respective
reasonable efforts to renegotiate the offending provisions to best accomplish
the original intentions of the parties.

         15.4     WAIVER

         A waiver by either party of any term or condition of this Agreement in
any one instance shall not be deemed or construed to be a waiver of such term
or condition for any similar instance in the future or of any subsequent breach
hereof. All rights, remedies, undertakings, obligations and agreements
contained in this Agreement shall be cumulative and none of them shall be a
limitation of any other remedy, right, undertaking, obligation or agreement.

the Transaction Documents, then the provisions of this Agreement shall prevail.

         15.8     FORCE MAJEURE

         Neither party shall be liable for failure to perform or delay in
performing obligations set forth in this Agreement, and no party shall be

long as, such failure, delay, breach or default is due to natural disasters or
any similar causes reasonably beyond the control of such party. Any party
desiring to invoke the protection of force majeure shall promptly notify the
other party of such desire and shall use reasonable efforts to resume
performance of its obligations.

         15.9     NO THIRD PARTY BENEFICIARIES
