eHealth Centers (the "Current eHealth Centers"), and ensure that each such
eHealth Center provides, at minimum, the functions set forth in Schedule 2.1.

     2.2 New eHealth Centers. In the event that (a) Medco develops additional
eHealth Centers, Merck shall have the right of first refusal to invest in such a
center. The scope and terms of any such a project will be determined by Medco at
its sole discretion. Medco may make Merck aware of any such intentions to
develop a center at any point in time (through written communication); Merck
will respond to Medco in writing regarding an interest in investing within 30
calendar days or it will be assumed that no current interest exists and Medco's

in Schedule 2.3 concerning the success of the eHealth Centers in attracting
Registered Members and influencing their behavior.

impact of the eHealth Centers using well-matched statistically significant
control groups to compare the behavior of patients who use the eHealth Centers
against the behavior of similar patients who did not use the eHealth Centers.

     2.5 Clarifying and Backup Data. Upon reasonable request by Merck, Medco
shall provide clarifications to and backup data for the reports and statistics
specified in Schedule 2.3, subject to Medco's duty to safeguard patient

Medco. Merck shall have the right, within reason, to request additional types of
information be gathered from eHealth users and analyses be performed on data
collected from or on eHealth Center users. Medco shall use its best efforts to

diligence, as Medco has used in the provision of similar services to Merck in

                                    ARTICLE V

year periods for the years 2003, 2004 and 2005.

     5.2 Termination. Merck may terminate this Agreement for any reason or no
reason, effective January 1, 2003 or at any later date, upon at least 90 days

Merck may also terminate this Agreement in part, by eliminating its request for

the event that Merck terminates this Agreement in part as to one or more of the
Women's Health (Osteoporosis) Center, the Arthritis Center or the Cardiovascular
Center (Hypertension and High Cholesterol), the fees payable under Schedule
3.1.A.1 shall be reduced by one third per year for each eHealth Center for which
services are terminated, and also reduced pro rata for the number of months left
in the year if the services are terminated mid-year. In the event that Merck
terminates this Agreement mid-year as to the Wellness (Vaccines) eHealth Center,
the fees payable under Schedule 3.1.A.2 shall be reduced pro rata for the number
of months left in the year.

     5.3 Effect of Termination. Termination of this Agreement shall relieve and
release the Parties from any further liabilities and obligations hereunder with
respect to the services terminated except any liabilities or obligations that
accrued prior to the effective date of such termination and except as provided
in Section 5.4.

                                 INDEMNIFICATION

     11.1 Indemnification. Medco shall indemnify and hold harmless the Merck
Indemnitees (as defined in the Indemnification Agreement) in respect of all
Liabilities (as defined in the Indemnification Agreement) related to, arising
from, asserted against or associated with Medco's providing services hereunder.
Such indemnification obligation shall be a Medco Liability for purposes of the

to indemnification shall govern with respect thereto. Merck shall indemnify and
hold harmless the Medco Indemnitees (as defined in the Indemnification

Agreement) related to or arising from Merck's provision of content under Section
2.6 of this Agreement. Such indemnification obligation shall be a Merck
Liability for purposes of the Indemnification Agreement, and the provisions of

     12.1 Any dispute, controversy or claim arising between the Parties relating
to the interpretation or performance of this Agreement shall be resolved in
accordance with the provisions of Article III of the Indemnification Agreement.

     12.2 Injunctive Relief. Notwithstanding the provisions of Section 12.1,

<PAGE>

Medco acknowledges that any violation of Article(s) II, VI and/or VIII of this
Agreement will cause Merck immediate and irreparable harm that monetary damages
cannot adequately remedy. The parties agree that, upon any actual or impending
violation of Article(s) II, VI and/or VIII of this Agreement, in addition to any
money damages or other legal remedy that Merck may have, Merck shall also be
entitled to equitable relief, including injunctive relief and specific
performance (and Medco shall not plead in defense thereto that there would be an
adequate remedy at law), without bond or proof of damages. Such equitable relief
may be sought in an arbitration proceeding pursuant to Section 3.1(c) of the
Indemnification Agreement (without first complying with the negotiation
provisions of Section 3.1(a) thereof) or in a court, subject to Section 14.2 of
this Agreement. In the event of litigation relating to this Agreement, if a
court of competent jurisdiction determines that Medco has breached Article(s)
II, VI and/or VIII of this Agreement, Medco shall be liable and pay to Merck the
reasonable legal fees and costs incurred in connection with such litigation,
including any appeal from such litigation.

     12.3 Limitation on Damages. In the event of a breach of this Agreement, the
damages (if any) payable by either Party shall not exceed the total annual
payments due under the Agreement for its entire Term as set forth in Schedule
3.1.A.

                                  ARTICLE XIII

                                  FORCE MAJEURE

     13.1 Neither Party shall be deemed to have breached this Agreement or to
have failed or delayed in the performance of all or any portion of its
obligations under this Agreement if such Party is prevented from doing so by a
cause or causes beyond its control, provided that such Party is using reasonable
commercial efforts to remedy its non-performance or to arrange for appropriate
alternative methods of performance. Without limiting the generality of the
foregoing, such causes include acts of God or the public enemy, fires, floods,
storms, earthquakes, locusts, tornadoes ("twisters"), mudslides, riots,
terrorism, strikes, lock-outs, wars and war-operations, restraints of government
power or communication line failure or other circumstances beyond such Party's
control, or by reason of the judgment, ruling or order of any court or agency of
competent jurisdiction or change of law or regulation subsequent to the
execution of this Agreement. If either Party is affected by a force majeure
event, such party shall, within 10 days of its occurrence, give notice to the
other Party stating the nature of the event, its anticipated duration and any
action being taken to avoid or minimize its effect. The suspension of
performance shall be of no greater scope and no longer duration than is required
and the non-performing Party shall use its best efforts to remedy its inability
to perform.

     13.2 If either Party's performance under this Agreement is suspended
pursuant to Section 13.1, the other Party's obligations (except for those
covered by Articles VI, VIII and XI) shall be suspended for the same period of
time. If Medco is unable substantially to perform its obligations under this
Agreement for more than 5 business days by reason of an act covered by Section
13.1, the fees payable by Merck shall be reduced pro rata for each additional
calendar day that Medco's non-performance continues. If Medco's suspension of
services continues for more than 30 days, Merck shall have the right to
terminate this Agreement on 7 days notice.

                                   ARTICLE XIV

                                  MISCELLANEOUS

with, and all Disputes hereunder shall be governed by, the procedural (except to

all matters regardless of the laws that might otherwise govern under principles
of conflicts of laws applicable thereto. Under no circumstances may any party
seek or be awarded punitive damages under this Agreement. Any state court
sitting in New York county, New York and/or the United States District Court for
the Southern District of New York shall have exclusive jurisdiction and venue,

objection it may now or hereafter have to such jurisdiction or the laying of
such venue over any Disputes between the parties that are permitted to be
brought in a court, or the enforcement of any decision of an arbitrator,
pursuant to Article III of the Indemnification Agreement. Each of the parties
hereby irrevocably waives any right to a jury trial with respect to a Dispute.

including its Schedules and table of contents, are for reference purposes only
and shall not affect in any way the meaning or interpretation of this Agreement.
Any capitalized term used in any Schedule but not otherwise defined therein,

is made in this Agreement to an Article or a Section, such reference shall be to
an Article or Section of this Agreement unless otherwise indicated.

     14.4 Notices. All notices and other communications required or permitted to

permitted hereby, neither Party may, directly or indirectly, in whole or in
part, whether by operation of law or otherwise, assign or transfer this
Agreement or its rights hereunder, without the other's prior written consent

option of such other party. Nevertheless, Merck may

<PAGE>

assign or transfer this agreement to a successor in interest in connection with
a corporate merger. Without limiting the foregoing, this Agreement will be
binding upon and inure to the benefit of the Parties and their permitted
successors and assigns. This Agreement, including the Schedules and the other
documents referred to herein, shall be binding upon and inure solely to the
benefit of each Party hereto and its legal representatives and successors and
assigns and nothing in this Agreement, express or implied, is intended to confer

by reason of this Agreement.

     14.6 Severability. If any term or other provision of this Agreement is
determined by a court, administrative agency or arbitrator, by any court or in
any binding arbitration, to be invalid, illegal or incapable of being enforced
by any rule of law or public policy, all other conditions and provisions of this
Agreement will nevertheless remain in full force and effect so long as the
economic or legal substance of the transactions contemplated hereby is not
affected in any manner materially adverse to any Party. Upon such determination
that any term or other provision is invalid, illegal or incapable of being
enforced, the Parties shall negotiate in good faith to modify this Agreement so
as to effect the original intent of the Parties as closely as possible in an
acceptable manner to the end that transactions contemplated hereby are fulfilled
to the fullest extent possible.

     14.7 Failure or Indulgence not Waiver; Remedies Cumulative. No failure or
delay on the part of either Party hereto in the exercise of any right hereunder
shall impair such right or be construed to be a waiver of, or acquiescence in,
any breach of any representation, warranty or agreement herein, nor shall any
single or partial exercise of any such right preclude the further exercise
thereof or of any other right. All rights and remedies existing under this
Agreement are cumulative to, and not exclusive of, any rights or remedies
otherwise available.

     14.8 Amendment. No change or amendment will be made to this Agreement
except by an instrument in writing signed on behalf of each of the Parties
hereto.
