participants and Synavant Inc. Disabled Employees under the flexible spending
accounts maintained by IMS Health (or any Affiliate thereof) on July 31, 2000.
IMS Health shall transfer to Synavant Inc. all recordkeeping information with
respect to such flexible spending accounts for the current calendar year.

         SECTION 5.4 Allocation of Liabilities.

                  (a) The Synavant Inc. Group shall retain responsibility for
and continue to pay all claims and administrative expenses relating to any
self-insured medical plan maintained by IMS Health (or any Affiliate thereof)
with respect to claims incurred before August 1, 2000, but which are paid on or
after August 1, 2000, by Synavant Inc. Employees, Synavant Inc. Disabled
Employees, Synavant Inc. COBRA participants and Synavant Inc. Retirees other
than Synavant Inc. Retiree Medical Recipients as well as their covered
dependents. Any claims and administrative expenses relating to the IMS Health
self-insured medical plan with respect to claims incurred before August 1, 2000,
but which are paid on or after August 1, 2000, by IMS Health Pre-Distribution
Employees who are not Synavant Inc. Employees will remain the responsibility of
The IMS Health Group.

                  (b) The IMS Health Group shall retain responsibility for and
continue to pay all premiums, expenses and benefits relating to the IMS Health
Employee Welfare Benefit Plans with respect to claims incurred (for self-insured
plans) or premiums due (for insured plans) from and after August 1, 2000 by IMS
Health Post-Distribution Employees, IMS Health Disabled Employees, IMS Health
COBRA participants, IMS Health Retirees and Synavant Inc. Retiree Medical
Recipients as well as their covered dependents.

                  (c) The Synavant Inc. Group shall retain responsibility for
and continue to pay all premiums, expenses and benefits relating to the Synavant
Inc. Group Employee Welfare Benefit Plans with respect to claims incurred (for
self-insured plans) or premiums due (for insured plans) from and after August 1,
2000 by Synavant Inc. Employees, Synavant Inc. Disabled Employees, Synavant Inc.
COBRA participants and Synavant Inc. Retirees other than Synavant Inc. Retiree
Medical Recipients as well as their covered dependents.

                  (d) For the purposes of this Section 5.4, a claim is deemed
incurred when the services that are the subject of the claim are performed; in
the case of life insurance, when the death occurs; in the case of long-term
disability, when the disability occurs; and, in the case of a hospital stay,
when the employee first enters the hospital. Notwithstanding the foregoing,
claims incurred by any employee of a pre-Distribution Subsidiary of IMS Health
or their covered dependents under any Employee Welfare Benefit Plan maintained
by such Subsidiary solely for the benefit of its employees and their dependents
shall, whether incurred prior to, on or after August 1, 2000, be the sole
responsibility and liability of that Subsidiary.

                  (e) The IMS Health Group shall be responsible for all COBRA
coverage for any IMS Health Retiree and any Synavant Inc. Retiree Medical
Recipient and his or her covered dependents who participated in an IMS Health
Employee Welfare Benefit Plan. As of August 1,
<PAGE>

2000, the Synavant Inc. Group shall be responsible for all COBRA coverage for
any Synavant Inc. Retiree other than an Synavant Inc. Retiree Medical Recipient
and his or her covered dependents who participated in an IMS Health Employee
Welfare Benefit Plan. Notwithstanding the foregoing, a pre-Distribution
Subsidiary of IMS Health shall be responsible for all COBRA coverage for its
former employees and covered dependents who participated in a plan maintained
solely for their benefit whether the applicable event occurs prior to, on or
after August 1, 2000. COBRA coverage to which an IMS Health Post-Distribution
Employee or his or her covered dependents is entitled as a result of a
qualifying event occurring on or after August 1, 2000 shall be the
responsibility of the IMS Health Group. COBRA coverage to which a Synavant Inc.
Employee or his or her covered dependents is entitled as a result of a
qualifying event occurring on or after August 1, 2000 shall be the
responsibility of the Synavant Inc. Group.

         SECTION 5.5 Allocation of the IMS Health's Self-Insured Medical Plan
Reserve for Claims Incurred But Not Yet Reported ("IBNR"). The IBNR reserve of
$952,000 will be allocated between the IMS Health Group and Synavant Inc. based
on the following methodology:

         The IBNR reserve will be divided based on the average number of IMS
Health Pre-Distribution Employees enrolled in May, June and July, 2000 who were
employees of the IMS Health Group (but not of the Synavant Inc.
Group) and who were employees of the Synavant Inc. Group.

         SECTION 5.6 Retiree Welfare Plans. The IMS Health Group shall be
responsible for providing retiree welfare benefits, where applicable, to IMS
Health Retirees, IMS Health Post-Distribution Employees and Synavant Inc.
Retiree Medical Recipients. In addition, IMS Health shall amend the IMS Health
retiree medical plan to provide to those Synavant Inc. Employees who were IMS
Health Pre-Distribution Employees and who were eligible for benefits under such
retiree medical plan on July 31, 2000, by having attained age 55 and having
completed ten years of service after age 45 as of July 31, 2000, as listed on
Schedule 5.6, such benefits as may be offered under such retiree medical plan
when such Synavant Inc. Employees retire or terminate employment with Synavant
Inc; subject, however, to the terms and conditions of any such plan, including
without limitation, any prescribed period within which such retiree medical
benefits must be elected upon retirement or termination of employment with
Synavant Inc. and further subject to the condition that any such amendment shall
satisfy any applicable nondiscrimination requirements of Section 105(h) of the
Code. Anything in this Section 5.6 to the contrary notwithstanding, nothing
herein shall be construed to prevent IMS Health from amending its retiree
medical plan or terminating such plan provided that such amendment or
termination is not designed to enable IMS Health to avoid the requirements of
this Section 5.6.

                                   ARTICLE VI
                               EQUITY-BASED PLANS

         SECTION 6.1 IMS Health Stock Options. Stock options awarded under the
IMS Health Stock Option Plans ("IMS Health Stock Options") shall be treated as
follows:

                  (a) IMS Health Post-Distribution Employees, IMS Health
Disabled Employees and IMS Health Non-Employee Directors. From and after the
Effective Time, each unexercised IMS Health Stock Option held by IMS Health
Post-Distribution Employees, IMS Health Disabled Employees, and IMS Health
Non-Employee Directors shall remain outstanding pursuant to the terms of the
award agreements and the IMS Health Stock Option Plans; provided, however, that
from and after such time, each unexercised IMS Health Stock Option shall be
adjusted by reference to the ratio of market prices of IMS Health Common Stock
before and after the
<PAGE>

Distribution, the objective being to maintain the then existing intrinsic value
of the IMS Health Stock Options and to maintain the ratio of the then existing
exercise price per share to the market value per share in accordance with
applicable accounting standards.

                  (b) Synavant Inc. Employees and Synavant Inc. Disabled
Employees. As of the Effective Time, (i) each unexercised IMS Health Stock
Option held by Synavant Inc. Employees and Synavant Inc. Disabled Employees
shall be cancelled except as provided in Schedule 6.1(a) and (ii) such
individuals shall except as provided in Schedule 6.1(a) receive replacement
stock options awarded under the Synavant Inc. Replacement Plans, which shall be
adopted by Synavant Inc. prior to the Effective Time. The number of shares of
Synavant Inc. Common Stock covered by each replacement stock option shall be
determined by reference to the ratio of market prices of IMS Health Common Stock
and Synavant Inc. Common Stock immediately before or after the Distribution, the
objective being to preserve the then intrinsic value of the unexercised IMS
Health Stock Options. The aggregate market value of the Synavant Inc. Common
Stock purchasable under the replacement stock options awarded under the Synavant
Inc. Replacement Plans immediately after the Distribution shall be approximately
equal to the aggregate market value of the IMS Health Common Stock that was
purchasable under the IMS Health Stock Options immediately before the
Distribution, with the aggregate exercise price of the replacement stock options
being the same as the IMS Health Stock Options except to the extent that the
number of shares purchasable is rounded down to the nearest whole share. Except
as otherwise provided in the Synavant Inc. Replacement Plans, all other terms of
the replacement stock options shall remain substantially identical to the terms
of the cancelled IMS Health Stock Options.

                  (c) Synavant Inc. Retirees and IMS Health Retirees. As of the
Effective Time, (i) each unexercised IMS Health Stock Option held by Synavant
Inc. Retirees and IMS Health Retirees shall be adjusted in substantially the
same manner as employees of the IMS Health Group and (ii) Synavant Inc. may
offer to such Synavant Inc. Retirees and IMS Health Retirees, and the Synavant
Inc. Committee shall determine, alternative adjustments or substitutions,
provided such Retirees agree to surrender their adjusted IMS Health Stock
Options.

                  (d) Exceptions. Certain IMS Health Stock Options described
above may not be adjusted as described above, but instead shall be subject to
such conditions as the Committee shall determine to the extent necessary to
avoid adverse tax consequences to option holders who are not U.S. residents.

         SECTION 6.2 Restricted Stock and Restricted Stock Units.

                  (a) Restricted stock awarded under the IMS Health Stock Option
Plans ("IMS Health Restricted Stock") held by IMS Health Post-Distribution
Employees and IMS Health Non-Employee Directors will be canceled prior to the
Distribution Date. Immediately following the Distribution Date, new shares of
IMS Health Restricted Stock will be granted equal to the number of shares held
prior to the cancellation, plus an additional number of shares that provides the
economic equivalent of the Synavant Inc. restricted stock (the "Synavant Inc.
Restricted Stock") that would have been received with respect to the canceled
IMS Health Restricted Stock in connection with the Distribution, subject to
rounding down to the nearest whole number of shares. Such newly granted shares
of IMS Health Restricted Stock shall be subject to a restriction period equal to
the restriction period remaining with respect to the canceled IMS Health
Restricted Stock and all other terms of the newly granted IMS Health Restricted
Stock shall remain substantially identical to the terms of the canceled IMS
Health Restricted Stock. With respect to IMS Health Restricted Stock held by
Synavant Inc. Employees, such IMS Health Restricted Stock will be replaced by
Synavant Inc. Restricted Stock with reference to the ratio of
<PAGE>

the market price of IMS Health Common Stock and Synavant Inc. Common Stock
immediately before or after the Distribution so that the aggregate market value
of the Synavant Inc. Restricted Stock immediately after the Distribution will
equal the aggregate market value of the IMS Health Restricted Stock immediately
before the Distribution, subject to rounding down to the nearest whole number of
shares. Except as otherwise provided in the Synavant Inc. Replacement Plans, all
other terms of the replacement Synavant Inc. Restricted Stock shall remain
substantially identical to the terms of the replaced IMS Health Restricted
Stock.

                  (b) Restricted stock units awarded under the IMS Health Stock
Option Plans ("IMS Health Restricted Stock Units") and restricted stock units
received as a result of the Distribution ("Synavant Inc. Restricted Stock
Units") will be adjusted or converted so that, after the Distribution, IMS
Health Post Distribution Employees will hold awards that relate solely to IMS
Health Common Stock and Synavant Inc. Employees will hold awards that relate
solely to Synavant Inc. Common Stock. With respect to IMS Health Post
Distribution Employees, such adjustment or conversion will be done such that the
award immediately after the Distribution will have the same aggregate market
value as the award immediately before the Distribution, subject to rounding down
to the nearest whole number of stock units. With respect to Synavant Inc.
Employees, such awards will be replaced with reference to the ratio of the
market price of IMS Health Common Stock and Synavant Inc. Common Stock
immediately before or after the Distribution so that the aggregate market value
of the Synavant Inc. Restricted Stock Units immediately after the Distribution
will equal the aggregate market value of the IMS Health Restricted Stock Units
immediately before the Distribution, subject to rounding down to the nearest
whole number of stock units. Except as otherwise provided in the Synavant Inc.
Replacement Plans, all other terms of the replacement Synavant Inc. Restricted
Stock Units shall remain substantially identical to the terms of the replaced
IMS Health Restricted Stock Units.

         SECTION 6.3 Executive Annual Incentive Plan. Outstanding awards under
the IMS Health Executive Annual Incentive Plan shall be treated as determined by
IMS Health and Synavant Inc., respectively.

         SECTION 6.4 IMS Health Employee Stock Purchase Plan.

                  (a) From and after the Effective Time, IMS Health shall
continue to sponsor the IMS Health Employee Stock Purchase Plan.

                  (b) As of the Effective Time, Synavant Inc. shall adopt the
Synavant Inc. Employee Stock Purchase Plan for the benefit of Synavant Inc.
Employees.

         SECTION 6.5 Allocation of Liabilities. The Synavant Inc. Group shall
assume all Liabilities with respect to awards granted to Synavant Inc.
Employees, Synavant Inc. Retirees and Synavant Inc. Disabled Employees pursuant
to the Synavant Inc. Replacement Option Plan. The IMS Health Group shall retain
all other Liabilities with respect to awards granted pursuant to the IMS Health
Stock Option Plans (including, but not limited to, awards granted to IMS Health
Post-Distribution Employees).

Employee Benefit Plans maintained outside the United States for their respective
Employees.
