party, structured generally (unless otherwise determined by the Steering
Committee) to include a Project Executive (with coordination authority over
sales efforts to multiple targeted customers), a Relationship Executive
(corresponding to the specific targeted customer), and a sales/follow-up team.
The parties will coordinate all sales team correspondence to each targeted
customer through the corresponding Project and Relationship Executives to enable
a unified, seamless message from the combined sales team. Project Executives and
Relationship Executives will be designated from time to time by the Steering
Committee.

                  (c)      Joint Bids. The parties agree to coordinate all joint
sales bids for services provided through use of the Tools under this Agreement.
The sales teams shall, together with the Steering Committee, determine on a
bid-by-bid basis, issues relating to (1) the work to be performed by and the
compensation to be paid to each party, (2) pricing of the services, (3) which
party (based on preexisting relationships with the customer or otherwise) shall
take the lead in the bid process, (4) the contractual structure of any
transaction with a customer (through a prime and subcontractor arrangement or
otherwise), and (5) such other matters as are determined by the parties.

                  (e)      Primary Sales Force Responsibility. Quintiles will
bear primary responsibility for sales force activities for services related to
the drug development and physician detailing Tool Groups. HWMD will bear primary
responsibility for sales force activities for services relating to the
direct-to-consumer Tool Group.

                  (f)      Package Orientation. The parties intend to market
services based on the Tool Groups primarily as a single package including all
three Tool Groups, but recognize that some customers may require the right to
purchase services provided through the use of Tools individually or on a Tool
Group basis. The Steering Committee will be responsible to establish and adapt
price levels and models for custom sales.

         5.2      SPECIFIC MARKETING ACTIVITIES. The Work Plan for each Alliance
Product will specify the manner (if unique) in which the parties will market
such Alliance Product, along with the specific resources (if any) each party
will provide for that purpose. Each party will use commercially reasonable
efforts to conduct the marketing activities specified in each such Work Plan, in
the manner and on the schedule specified therein.

         5.3      OTHER MARKETING ACTIVITIES.

                  (a)      General. In addition to the marketing activities
designated in Work Plans for specific Tools, HWMD and Quintiles will engage in
such other marketing activities as the Steering Committee shall determine from
time to time, such as in connection with establishing a marketing infrastructure
for Alliance activities, preparing periodic marketing plans, developing general
marketing collateral, or otherwise. The Steering Committee may develop Work
Plans to address all such activities as it determines. Each party will conduct
its respective activities designated in each such Work Plan in the manner and on
the schedule specified therein.

                  (b)      Procedures. The Steering Committee may develop sales
procedures from time to time in its discretion for such matters as contact
management and enhancement, coordinated bid preparation, and contracting, and
such other matters as the Steering Committee determines. Each party will cause
its Alliance sales personnel to comply with all such procedures adopted by the
Steering Committee as in effect from time to time.

                            PAYMENTS; REVENUE SHARING

         6.1      PAYMENTS FOR DEVELOPMENT WORK. Quintiles will compensate HWMD
for development activities as follows:

                  (a)      For development of the Tools in the Initial Toolkit
and of any post-release enhancements during the year after any such Tool is
first made generally available, Quintiles shall


                                  Page 10 of 20
<PAGE>   12

pay HWMD at HWMD's "fully-loaded" development cost for Development Personnel
(determined as a function of salary and an overhead allotment agreed to by the
Steering Committee) and actual costs and expenses otherwise incurred in carrying
out a Work Plan approved by the Steering Committee ("Costs").

                  (b)      For development of Tools other than those in the
Initial Toolkit, of any post-release enhancements for any such Tool, and of any
post-release enhancements of Tools in the Initial Toolkit following the year
after any such Tool is first made generally available, Quintiles shall pay HWMD
such development fees as are determined by the Steering Committee and set forth
in the applicable Work Plan.

                  (c)      HWMD shall provide to Quintiles monthly invoices for
Costs which shall provide all information reasonably necessary for the
computation or conformation of the payments described in the invoices. Any
payments for Costs will be paid by Quintiles to HWMD within thirty (30) days
after Quintiles' receipt of such invoice. Quintiles will pay interest of 1% per
month on amounts not paid within such 30 day period, unless Quintiles delivers,
in good faith, notice to HWMD disputing such payment in reasonable detail.

         6.2      REVENUE SHARING.

                  The parties will share their respective revenues from the
sales of services provided through use of the Tools in the manner determined by
the Steering Committee at the time of each bid to a potential customer. The
Alliance Guidelines include a model of the parties' revenue sharing expectations
by Product Channel as of the date of this Agreement.

         6.3      AUDITS. Each party will maintain records reasonably sufficient
to document and record its shared revenues for Tools; and each shall have the
right to audit the other's books and records on a reasonable basis to confirm
the accuracy thereof solely relative to shared revenues. The parties will
address any apparent payment discrepancies promptly and in good faith, and the
affected party promptly will correct any confirmed over- or under-payment. Each
party may perform such audits up to twice per calendar year during the other
party's normal business hours by providing the audited party with at least five
business days advance written notice. In performing such audits, the auditing
party will not unduly interfere with the operation of the audited party's other
business activities, and the auditing party will comply with the audited party's
reasonable safety and security policies and procedures.

         6.4      OTHER COSTS OF PERFORMANCE. Except as otherwise specifically
provided in this Agreement, each party will bear the costs and expenses of
performing its obligations hereunder. Neither party shall be obligated to pay
any taxes of the other or any other expenses for which the other party may be
liable based upon or in connection with the transactions contemplated by this
Agreement.

party and its respective Affiliates will be permitted to disclose the other
party's Confidential Information as and to the extent required by applicable
law, provided the party required to make any such disclosure notifies the party
whose Confidential Information is required to be disclosed as far in advance of
the required disclosure as is reasonably practicable under the circumstances and
cooperates with such party (if reasonably requested to do so, and at the
requesting party's expense) to secure confidential treatment for the required
disclosure. Nothing in this Agreement shall prohibit HWMD from using or
disclosing any information learned by its employees or retained in such
employees memory after their last exposure to materials containing Confidential
Information, to the extent such information comprises software programming,
Internet product development, or hosting techniques applicable generally to
HWMD's business and products.

                                   ARTICLE IX
                              TERM AND TERMINATION

         9.1      INITIAL TERM; RENEWAL TERM. This Agreement shall commence upon
the date specified above in the preamble and continue thereafter for ten (10)
years. At the end of the initial term, this Agreement shall renew automatically
for successive two (2) year periods, unless either HWMD or Quintiles notifies
the other in writing of its intention to terminate this Agreement at least one
hundred eighty (180) days prior to the beginning of the applicable renewal term.

         9.2      TERMINATION

other party has defaulted in any material obligation under this Agreement and
failed to cure such default within sixty (60) days after written notice thereof
from the terminating party.

                  (b)      Either party may terminate this Agreement by
immediate written notice if the other party becomes insolvent or if a court of
competent jurisdiction enters an order or decree in


                                  Page 13 of 20
<PAGE>   15

for reorganization or appointing a custodian for all or substantially all its
assets or ordering the liquidation of such party.

obligations under Section 6.3 (Audits), and Articles VII (Intellectual Property
Ownership), VIII (Confidentiality), and X (Miscellaneous) will survive any

expiration of this Agreement, each party shall deliver to the other all copies
of all Confidential Information of the other party in its possession or control

Quintiles a service agreement for a period of up to two years, under which HWMD
shall continue to operate the Tools on behalf of Quintiles and facilitate the
transition of the Tools to another platform, all on HWMD's then-current standard
pricing and other terms and conditions. HWMD shall also include a listing of all
third party software contained in the Tools, and will sublicense or assign
HWMD's rights in such software to Quintiles where HWMD possesses the right to do
so.

                               DISPUTE RESOLUTION

         10.1     DISPUTE RESOLUTION.

                  (a)      Internal Review. In the event that a dispute,
difference or question arises pertaining to any matters which are the subject of
the Alliance ("DISPUTE"), and either party so requests in writing, prior to the
initiation of any formal legal action, the following dispute resolution shall
apply:

                           (1)      The Steering Committee will use its good
faith efforts to resolve the Dispute within ten (10) days. If the Steering
Committee is unable to resolve the Dispute in such period, the Steering
Committee will refer the Dispute to the Executive Sponsors as set forth in
subitem (2) below.

                           (2)      For all Disputes referred to the Executive
Sponsors from the Steering Committee above, the Executive Sponsors shall use
their good faith efforts to resolve the Dispute within twenty (20) days after
such referral. If the Executive Sponsors are unable to resolve the Dispute in
such period, the Executive Sponsors will refer the Dispute to the Chief
Executive Officers of HWMD and Quintiles as set forth in subitem (3) below.

                           (3)      For all Disputes referred to the Chief
Executive Officers from the Executive Sponsors above, the Chief Executive
Officers shall use their good faith efforts to resolve the Dispute within twenty
(20) days after such referral.

                  (b)      Mediation. In the event of a Dispute which cannot be
resolved by the Chief Executive Officers, either party may commence a
non-binding mediation to resolve the Dispute by providing written notice to the
other party (a "MEDIATION NOTICE") informing the other party of the dispute and
the issues to be resolved and containing a list of five (5) recommended
individuals to


                                  Page 14 of 20
<PAGE>   16

serve as the mediator. Within ten (10) business days after the receipt of a
Mediation Notice, the other party shall respond by written notice to the party
initiating mediation, providing a list of five (5) recommended individuals to
serve as the mediator and which adds additional issues to be resolved. The
recommended mediators shall be individuals with experience in the pharmaceutical
and healthcare technology industries and shall not be any employee, director,
shareholder or agent of either party or an Affiliate of either party, or
otherwise involved (whether by contract or otherwise) in the affairs of either
party. If, within twenty (20) business days after receipt of the Mediation
Notice, the parties shall have been unable to agree upon an individual to serve
as mediator, or to the extent the mediator selected by the parties is unable to
resolve the dispute, the dispute will be settled by final and binding
arbitration conducted in the manner described in subsection (c) below. If,
within twenty (20) business days after receipt of the Mediation Notice, the
parties shall have agreed upon an individual to serve as mediator, the mediator
shall conduct a mediation in an effort to resolve the dispute, employing
commercially reasonable procedures selected by the mediator in consultation with
the parties, completing such mediation no later than sixty (60) days after
engagement.

                  (c)      Arbitration. Binding arbitration, if necessary, shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association, as in effect at the time of the arbitration hearing,
such arbitration to be completed in a ninety (90) day period. The arbitration
panel will be composed of three arbitrators, one of whom will be chosen by HWMD,
one by Quintiles, and the third by the two so chosen. If both or either of HWMD
or Quintiles fails to choose an arbitrator or arbitrators within fourteen (14)
days after receiving notice of commencement of arbitration, or if the two
arbitrators fail to choose a third arbitrator within fourteen (14) days after
their appointment, the American Arbitration Association shall, upon the request
of both or either of the parties to the arbitration, appoint the arbitrator or
arbitrators required to complete the panel. The decision of the arbitrators
shall be final and binding on the parties, and specific performance may be
ordered by any court of competent jurisdiction.

                  (d)      Costs. The parties shall bear their own costs in
preparing for and participating in the resolution of any dispute under this
Article, and the costs of mediator(s) and arbitrator(s) shall be equally divided
between the parties.

                  (c)      Each of HWMD's employees and consultants who has been
or will be involved in the development of the Tools, or who will have access to
any Confidential Information of Quintiles, will have signed, before beginning
such involvement, an agreement with HWMD with respect to proprietary rights and
confidentiality which complies with the terms of this Agreement.

         11.3     VIRUS WARRANTY. HWMD warrants that HWMD has implemented all
measures used in its normal business, including at a minimum commercially
reasonable measures, to ensure that the Tools do not contain any virus or any
other contaminant, including but not limited to codes, commands or instructions
that may be used to access, alter, delete, damage, disable, cause disruption of

Quintiles data or information.

         11.4     YEAR 2000 WARRANTY. HWMD warrants to Quintiles that it shall

         12.1     DUTY TO INDEMNIFY BY HWMD. HWMD will, at its expense, defend,
indemnify, hold Quintiles harmless, from and against any damage, liability, cost
or expense (including reasonable attorneys' fees and court costs) arising out of
or resulting from any claim, suit or other proceeding in which it is alleged

proceeding; (ii) provide HWMD with all reasonable information and assistance, at
HWMD's expense, to defend or settle such a claim, suit or proceeding; and (iii)

claim specified in Section 12.1, then HWMD, at its sole option and expense, will
either: (i) procure for Quintiles a license to continue using the Tools in
accordance with the terms of this Agreement; or (ii) modify the allegedly

the Tools with the Specifications; or (iii) if such is not reasonably possible,
then instruct Quintiles to cease use of the infringing item and the parties will
use the dispute resolution process set out in Article X to adjust this Agreement
or the Work Plan in question to compensate.

         12.3     DUTY TO INDEMNIFY BY QUINTILES. Quintiles will, at its
expense, defend, indemnify, hold HWMD harmless, from and against any damage,
liability, cost or expense (including reasonable attorneys' fees and court
costs) arising out of or resulting from any claim, suit or other proceeding in
which it is alleged that the requirements or specifications produced by
Quintiles for the Tools or HWMD's exercise of its rights in the requirements or
