                                                                  EXECUTION COPY

Synavant Inc.
3445 Peachtree Road, NE
Suite 1400
Atlanta, GA 30326

Attention: Mr. Matthew Friedman

Gentlemen:

      SunTrust Bank (the "BANK") is pleased to advise Synavant Inc. (the
"COMPANY") that the Bank has approved, subject to the conditions outlined in
this letter (the "AGREEMENT"), a committed revolving credit facility (the
"FACILITY"). The amount borrowed or utilized under the Facility shall not exceed
$20,000,000 at any one time outstanding. The Facility shall terminate on the
earlier of (i) December 31, 2000 and (ii) 90 days after the Effective Date (the
"TERMINATION DATE"); PROVIDED, that if the Effective Date has not occurred on or
before October 2, 2000, the parties hereto agree that this Agreement shall be
cancelled on such date, and the Bank shall have no obligation hereunder.

1.    THE FACILITY

      The Company may from time to time before the Termination Date borrow Base
Rate Loans and Eurodollar Loans (each, "LOAN" and collectively, the "LOANS") and
enter into foreign exchange contracts on a spot and forward basis (each, a "FX
CONTRACT" and collectively, the "FX CONTRACTS"). The aggregate outstanding
amount of the Loans shall not at any time exceed $20,000,000, LESS the Total FX
Risk Exposure, as determined in accordance with Section 1.8 hereof. The Company
may borrow, repay and reborrow Loans in accordance with the terms hereof.

      1.1   BORROWING PROCEDURES

            (A) BASE RATE LOANS. Each Base Rate Loan shall be made upon prior
written notice from any Authorized Officer received by the Bank not later than
11:00 a.m. (New York City time) on the proposed borrowing date. Each such notice
shall specify (i) the borrowing date, which shall be a Banking Day, and (ii) the
amount of such Loan. Each Base Rate Loan shall be in a minimum amount of
$1,000,000 and in an integral multiple of $250,000.

            (B) EURODOLLAR LOANS. Each Eurodollar Loan shall be made upon prior
written or telephonic notice from any Authorized Officer received by the Bank
(which notice shall be irrevocable once given and, if given by telephone, shall
be promptly confirmed in

<PAGE>

writing) not later than 1:00 p.m. (New York City time) on the third Banking Day
preceding the commencement of an Interest Period for a Eurodollar Loan or the
end of an Interest Period applicable to a Eurodollar Loan. Each such notice
shall specify (i) the borrowing date, which shall be a Banking Day, (ii) the
amount of such Eurodollar Loan, and (iii) the Interest Period for such
Eurodollar Loan. If such Eurodollar Loan is to continue as a Eurodollar Loan,
the Company shall notify the Bank of the new Interest Period selected therefor,
and in the event the Company shall fail to so notify the Bank, such Eurodollar
Loan shall automatically be converted into and added to the Base Rate Loan as of
and on the last day of such Interest Period; PROVIDED, HOWEVER, that anything
contained herein to the contrary notwithstanding, the obligation of the Bank to
create or continue any Eurodollar Loan or to convert any part of the Base Rate
Loan into a Eurodollar Loan shall be conditioned upon the fact that at the time
no Unmatured Event of Default or Event of Default shall have occurred and be
continuing, except that during the existence of an Unmatured Event of Default
(but not an Event of Default) the Company may request the continuation of any
Eurodollar Loan into another Eurodollar Loan with an Interest Period not in
excess of one (1) month. Each Eurodollar Loan shall be in a minimum amount of
$1,000,000 and in an integral multiple of $500,000.

      1.2   INTEREST

            (A) BASE RATE LOANS. The unpaid principal of each Base Rate Loan
shall bear interest prior to maturity at a rate per annum, equal to the Base
Rate as in effect from time to time. Accrued interest on each Base Rate Loan
shall be payable monthly in arrears on the last Banking Day of each calendar
month, and on the Termination Date.

            (B) EURODOLLAR LOANS. The unpaid principal amount of each Eurodollar
Loan shall bear interest prior to maturity at a rate per annum equal to LIBOR as
in effect for the Interest Period with respect to such Eurodollar Loan PLUS 75
basis points. Accrued interest on each Eurodollar Loan shall be payable on the
last Banking Day of the Interest Period applicable to such Loan, and on the
Termination Date.

            (C) INTEREST AFTER MATURITY. Any principal of any Loan which is not
paid at maturity, whether at the stated maturity, upon acceleration or
otherwise, shall bear interest from and including the date such principal shall
have become due to (but not including) the date of payment thereof in full at a
rate per annum equal to the greater of (i) the Base Rate from time to time in
effect plus 4% per annum, or (ii) 4% per annum in excess of the rate applicable
to such Loan immediately prior to its maturity. After maturity, accrued interest
shall be payable ON DEMAND.

            (D) MAXIMUM RATE. In no event shall the interest rate applicable to
any amount outstanding hereunder exceed the maximum rate of interest allowed by
applicable law, as amended from time to time. Any payment of interest or in the
nature of interest in excess of such limitation shall be credited as a payment
of principal unless the Company shall request the return of such amount.

                                       2
<PAGE>

            (E) METHOD OF CALCULATING INTEREST AND FEES. Interest on each Loan
and all fees shall be computed on the basis of a year consisting of 360 days and
paid for actual days elapsed, except that interest on Base Rate Loans will be
computed on the basis of a year of 365 or 366 days (as the case may be) for the
actual number of days elapsed.

      1.3   DISBURSEMENTS AND PAYMENTS

            The Bank shall transfer the proceeds of each Loan as directed by an
Authorized Officer. Each Base Rate Loan shall be payable on the Termination
Date. Each Eurodollar Loan shall be payable on the earlier of the last Banking
Day of the Interest Period applicable thereto or the Termination Date. All
payments to the Bank shall be made at the office of the Bank located at 25 Park
Place, 21st Floor, Atlanta, GA 30303, or at such other address as the Bank shall
specify to the Company in writing. Any payment that shall be due on a day, which
is not a Banking Day, shall be payable on the next succeeding Banking Day,
subject to the definition of "Interest Period". Anything contained herein to the
contrary notwithstanding, all payments and collections received in respect of
the Indebtedness evidenced by the Note, in each instance, by the Bank after the
occurrence of an Event of Default shall be distributed as follows: (i) first, to
the payment of any outstanding costs and expenses incurred by the Bank in
preserving or enforcing fights under the Loan Documents and in any event
including all costs and expenses of a character which the Company has agreed to
pay under Section 11.3 hereof; (ii) second, to the payment of any outstanding
interest or other fees or amounts due under the Loan Documents other than for
principal; and (iii) third, to the payment of the principal of the Note.

      1.4   PREPAYMENT

            (A) Subject to Section 3.7, the Company may, at any time or from
time to time prepay Base Rate Loans in whole or in part in minimum amounts of
$1,000,000 or any multiple of $250,000 in excess thereof and Eurodollar Rate
Loans in whole or in part in minimum amounts of $5,000,000 or any multiple of
$500,000 in excess thereof. Each prepayment shall be made upon not less than one
Banking Day's irrevocable written notice to the Bank with respect to Base Rate
Loans and not less than three Banking Days' irrevocable written notice to the
Bank with respect to Eurodollar Rate Loans. Such notice of prepayment shall
specify the date and amount of such prepayment and the type(s) of Loans to be
prepaid.

            (B) The Company shall be required to prepay Loans to the extent that
the outstanding principal amount of all Loans and the Total FX Risk Exposure
exceeds at any time the then outstanding amount of the Facility.

      1.5   NOTE

            The Company's obligations with respect to the Loans shall be
evidenced by a note in the form attached as EXHIBIT A (the "NOTE"). The amount,
the rate of interest for each Loan and the Interest Period (if applicable) shall
be endorsed by the Bank on the schedule attached to the Note, or at the Bank's
option, in its records, which schedule or records shall be conclusive, absent
manifest error.

      1.6   REDUCTION OF FACILITY

            The Facility amount is subject to reduction from time to time
pursuant to this Section 1.6.

            (A) OPTIONAL. The Company may, from time to time on any Banking Day,
voluntarily cancel or reduce any unused amount of the Facility; PROVIDED,
HOWEVER, that all such reductions shall require at least five (5) Banking Days'
prior notice to the Bank and be permanent, and any partial reduction of the
Facility shall be in an integral multiple of $5,000,000.

            (B) MANDATORY. On the Termination Date, the amount of the Facility
shall be reduced to zero.

      1.7    INTENTIONALLY OMITTED

      1.8       FOREIGN EXCHANGE CONTRACTS

            The Company may use the Facility for FX Contracts on a spot and/or
forward basis upon terms and conditions negotiated separately with the Bank and
pursuant to customary documentation acceptable to the Bank; PROVIDED, that at no
time may the Total FX Risk Exposure exceed the lesser of (i) $4,000,000 and (ii)
the then outstanding amount of the Facility LESS the principal amount of all
outstanding Loans. No FX Contract may have a maturity date that extends beyond
the Termination Date.

2.    FEES

      The Company agrees to pay to the Bank (a) a facility fee of $150,000
payable (i) $75,000 on the Agreement Date, which payment shall be nonrefundable,
and (ii) $75,000 on the Effective Date and (b) a commitment fee on the actual
daily unused amount of the Facility at the rate per annum equal to 50 basis
points (as determined by the Bank and notified to the Company) that begins to
accrue on the Effective Date and is payable on the last Business Day of each
calendar month and on the Termination Date.

3.    ADDITIONAL PROVISIONS RELATING TO LOANS.

      3.1   INCREASED COSTS

      The Company agrees to reimburse the Bank for any increase in the cost to
the Bank of, or any reduction in the amount of any sum receivable by the Bank in
respect of, making or maintaining any Eurodollar Loans relating to the adoption
of any law, rule or regulation or any change therein or any change in the
interpretation of administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration

                                       4
<PAGE>

thereof. The additional amount required to compensate the Bank for such
increased cost or reduced amount shall be payable by the Company to the Bank
within five days of the Company's receipt of written notice from the Bank
specifying such increased cost or reduced amount and the amount required to
compensate the Bank therefor, which notice shall, in the absence of manifest
error, be conclusive and binding on the Company. In determining such additional
amount, the Bank may use reasonable averaging, attribution and allocation
methods.

      3.2    DEPOSITS UNAVAILABLE OR INTEREST RATE UNASCERTAINABLE;
             IMPRACTICABILITY

      If the Company has notified the Bank of its intention to borrow a
Eurodollar Loan for an Interest Period and the Bank determines (which
determination shall be conclusive and binding on the Company) that:

            (A) deposits of the necessary amount for such Interest Period are
not available to the Bank in the London interbank market or, by reason of
circumstances affecting such market, adequate and reasonable means do not exist
for ascertaining LIBOR for such Interest Period; or

            (B) LIBOR will not adequately and fairly reflect the cost to the
Bank of making or funding a Eurodollar Loan for such Interest Period, or

            (C) the making or funding of Eurodollar Loans has become
impracticable as a result of any event occurring after the date of this
Agreement which, in the opinion of the Bank, materially and adversely affects
such Loans or the interbank Eurodollar market;

then any notice of a Eurodollar Loan previously given by the Company and not yet
borrowed shall be deemed to be a notice to make a Base Rate Loan.

      3.3   CHANGES IN LAW RENDERING EURODOLLAR LOANS UNLAWFUL

      If at any time due to the adoption of, or change in, any law, rule,
regulation, treaty or directive or in the interpretation or administration
thereof by any Governmental Authority charged with the interpretation or
administration thereof, or for any other reason arising subsequent to the date
hereof, it shall become (or, in the good faith judgment of the Bank, raise a
substantial question as to whether it is) unlawful for the Bank to make or fund
any Eurodollar Loan, Eurodollar Loans shall not be made hereunder for the
duration of such illegality. If any such event shall make it unlawful for the
Bank to continue any Eurodollar Loans previously made by it hereunder, the
Company shall, after being notified by the Bank of the occurrence of such event,
on such date as shall be specified in such notice, either convert such
Eurodollar Loan to a Base Rate Loan or prepay in full such Eurodollar Loan,
together with accrued interest thereon, without any premium or penalty (except
as provided in Section 3.7).

      3.4   DISCRETION OF THE BANK AS TO MANNER OF FUNDING

                                       5
<PAGE>

      The Bank shall be entitled to fund and maintain its funding of all or any
part of the Loans in any manner it sees fit; it being understood, however, that
for purposes of this Agreement and the Note, all determinations hereunder and
thereunder (including, but not limited to, any determination pursuant to Section
3.3) shall be made as if the Bank had actually funded and maintained each
Eurodollar Loan during the Interest Period for such Eurodollar Loan through the
purchase of deposits having a term corresponding to such Interest Period and
bearing an interest rate equal to LIBOR for such Interest Period.

      3.5   INTENTIONALLY OMITTED

      3.6   INCREASED CAPITAL COSTS

      If any change in, or the introduction, adoption, effectiveness,
interpretation, reinterpretation or phase-in of, any law or regulation,
directive, guideline, decision or request (whether or not having the force of
law) of any court, central bank, regulator or other Governmental Authority
affects or would affect the amount of capital required or expected to be
maintained by the Bank or any entity controlling the Bank, and the Bank
determines (in its sole and absolute discretion) that the rate of return an its
or such controlling entity's capital as a consequence of the Loans made by the
Bank or the commitment hereunder is reduced to a level below that which the Bank
or such controlling entity could have achieved but for the occurrence of any
such circumstance, then, in any such case, upon notice from time to time by the
Bank to the Company, the Company shall immediately pay directly to the Bank
additional amounts sufficient to compensate the Bank or such controlling entity
for such reduction in rate of return. A statement of the Bank as to any such
additional amount or amounts (including calculations thereof in reasonable
detail) shall, in the absence of manifest error, be conclusive and binding on
the Company. In determining such amount, the Bank may use reasonable averaging,
attribution and allocation methods.

      3.7   FUNDING LOSSES

      The Company will indemnify the Bank upon demand against any loss or
expense which the Bank may sustain or incur (including, without limitation, any
loss or expense sustained or incurred in obtaining, liquidating or employing
deposits or other funds acquired to effect, fund or maintain any Loan) as a
consequence of (i) any failure of the Company to make any payment when due of
any amount due hereunder, (ii) any failure of the Company to borrow a Loan on a
date specified therefor in a notice thereof, or (iii) any payment (including any
payment upon the Bank's acceleration of the Loans) or prepayment of any
Eurodollar Loan on a date other than the last day of the Interest Period for
such Loan.

            GUARANTEE AGREEMENT dated as of August 11, 2000 between IMS HEALTH
INCORPORATED, a Delaware corporation (the "GUARANTOR"), and SUNTRUST BANK, a
Georgia banking corporation (the "LENDER").

            Reference is made to that certain letter agreement dated as of
August 11, 2000 (as hereafter amended, extended, supplemented or otherwise
modified, the "LOAN AGREEMENT"; all defined terms used herein not otherwise
defined herein shall have the meanings ascribed to them therein) between the
Bank and Synavant, Inc., a Delaware corporation (the "BORROWER") and the Note to
be dated as of the Effective Date attached thereto (as amended, extended,
supplemented or otherwise modified from time to time, the "NOTE"), pursuant to
which the Lender has established a $20,000,000 revolving credit facility (the
"FACILITY") to the Borrower. The Borrower is a former subsidiary of the
Guarantor and, as part of the transactions contemplated under the Distribution
Agreement, the Guarantor has agreed to provide certain credit support to the
Borrower in order to effect the Distribution (as defined in the Distribution
Agreement). The obligation of the Lender to establish the Facility and to make
any Loans and/or to enter into any FX Contracts under the Facility is
conditioned on, among other things, the execution and delivery by the Guarantor
of this Guarantee Agreement (as it may hereafter be amended, extended,
supplemented or otherwise modified, the "GUARANTEE"). As consideration therefor
and in order to induce the Lender to establish the Facility and to make Loans
and to enter into FX Contracts thereunder, the Guarantor is willing to execute
this Guarantee.

            Accordingly, the parties hereto agree as follows:

            SECTION 1. GUARANTEE. The Guarantor unconditionally guarantees, as a
primary obligor and not merely as a surety, (a) the due and punctual payment of
(i) the principal of and premium, if any, and interest (including interest
accruing during the pendency of any bankruptcy, insolvency, receivership or
other similar proceeding, regardless of whether allowed or allowable in such
proceeding) on all Loans made pursuant to the Loan Agreement, when and as due,
whether at maturity, by acceleration, upon one or more dates set for prepayment
or otherwise, and (ii) all other monetary obligations, including all amounts due
under any FX Contract and all fees, costs, expenses and indemnities, whether
primary, secondary, direct, contingent, fixed or otherwise (including monetary
obligations incurred pursuant to Section 6(b) hereof and/or during the pendency
of any bankruptcy, insolvency, receivership or other similar proceeding,
regardless of whether allowed or allowable in such proceeding), of the Borrower
to the Lender under the Loan Agreement and/or any of the other Loan Documents to
which it is a party, and (b) the due and punctual performance of all covenants,
agreements, obligations and liabilities of the Borrower under or pursuant to
Loan Agreement and/or any of the other Loan Documents to which it is a party
(all the monetary and other obligations referred to in the preceding clauses (a)
and (b) being collectively called the "GUARANTEED OBLIGATIONS").

            SECTION 2. OBLIGATIONS NOT WAIVED. The Guarantor waives presentment
to, demand of payment from and protest to the Borrower of any of the Guaranteed
Obligations, and

                                      B-1
<PAGE>

also waives notice of acceptance of its guarantee and notice of protest for
nonpayment. The obligations of the Guarantor hereunder shall not be affected by
(a) the failure of the Lender to assert any claim or demand or to enforce or
exercise any right or remedy against the Borrower or any other guarantor under
the provisions of the Loan Agreement or the Note or otherwise, (b) any
rescission, waiver, amendment or modification of, or any release from any of the
terms or provisions of, this Guarantee, the Loan Agreement or the Note, or (c)
the failure to perfect any security interest in, or the release of, any of the
security held by or on behalf of the Lender pursuant to the Loan Agreement or
the Note.

            SECTION 3. GUARANTEE OF PAYMENT. Subject to Section 7(b) hereof, the
Guarantor agrees that its guarantee constitutes a guarantee of payment when due
and not of collection, and waives any right to require that any resort be had by
the Lender to any security held for payment of the Guaranteed Obligations or to
any balance of any deposit account or credit on the books of the Lender in favor
of the Borrower or any other person.

            SECTION 4. NO DISCHARGE OR DIMINISHMENT OF GUARANTEE. The
obligations of the Guarantor hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason (other than the
indefeasible payment in full in cash of the Guaranteed Obligations), including
any claim of waiver, release, surrender, alteration or compromise of any of the
Guaranteed Obligations, and shall not be subject to any defense or setoff,
counterclaim, recoupment or termination whatsoever by reason of the invalidity,
illegality or unenforceability of the Guaranteed Obligations or otherwise or the
failure to give any notice to the Guarantor as provided for in Sections 1 and 2
hereof. Without limiting the generality of the foregoing, the obligations of the
Guarantor hereunder shall not be discharged or impaired or otherwise affected by
the failure of the Lender to assert any claim or demand or to enforce any remedy
under the Loan Agreement or the Note, by any waiver or modification of any
provision of any thereof, by any default, failure or delay, willful or
otherwise, in the performance of the Guaranteed Obligations, or by any other act
or omission that may or might in any manner or to the extent vary the risk of
the Guarantor or that would otherwise operate as a discharge of the Guarantor as
a matter of law or equity (other than the indefeasible payment in full in cash
of all the Guaranteed Obligations).

            SECTION 5. DEFENSES OF BORROWER WAIVED. The Guarantor waives any
defense based on or arising out of any defense of the Borrower or the
unenforceability of the Guaranteed Obligations or any part thereof from any
cause, or the cessation from any cause of the liability of the Borrower, other
than the final and indefeasible payment in full in cash of the Guaranteed
Obligations. The Lender may, at its election, foreclose on any security held by
it by one or more judicial or nonjudicial sales, accept an assignment of any
such security in lieu of foreclosure, compromise or adjust any part of the
Guaranteed Obligations, make any other accommodation with the Borrower or any
other guarantor, without affecting or impairing in any way the liability of the
Guarantor hereunder, except to the extent the Guaranteed Obligations have been
fully, finally and indefeasibly paid in cash. The Guarantor waives any defense
arising out of any such election even though such election operates, pursuant to
applicable law, to impair or to extinguish any right of reimbursement or
subrogation or other right or remedy of the Guarantor against the Borrower or
any other guarantor, as the case may be, or any security.

            SECTION 6. AGREEMENT TO PAY; SUBORDINATION. (a) In furtherance of
the foregoing and not in limitation of any other right that the Lender has at
law or in equity against the Guarantor by virtue hereof, upon the failure of the
Borrower to pay any Guaranteed Obligation when and as the same shall become due,
whether at maturity, by acceleration, after notice of prepayment or otherwise,
the Guarantor hereby promises to and will forthwith pay, or cause to be paid, to
the Lender in cash the amount of such unpaid Guaranteed Obligation. Upon payment
by the Guarantor of any sums to the Lender, all rights of the Guarantor against
the Borrower arising as a result thereof by way of right of subrogation,
contribution, reimbursement, indemnity or otherwise shall in all respects be
subordinate and junior in right of payment to the prior indefeasible payment in
full in cash of all the Guaranteed Obligations. In addition, any indebtedness of
the Borrower now or hereafter held by the Guarantor is hereby subordinated in
right of payment to the prior indefeasible payment in full in cash of the
Guaranteed Obligations. If any amount shall erroneously be paid to the Guarantor
on account of (i) such subrogation, contribution, reimbursement, indemnity or
similar right or (ii) any such indebtedness of the Borrower, such amount shall
be held in trust for the benefit of the Lender and shall forthwith be paid to
the Lender to be credited against the payment of the Guaranteed Obligations,
whether matured or unmatured, in accordance with the terms of the Loan
Agreement.

            (b) Notwithstanding the foregoing, if the Borrower shall fail to pay
any Guaranteed Obligation when due and payable, the Lender agrees that, in lieu
of the immediate payment by the Guarantor as contemplated in Section 6(a), the
Guarantor shall pay to the Lender an amount equal to such unpaid Guaranteed
Obligations (including without limitation any estimated costs and expenses
(including estimated attorneys' fees) that the Lender may incur in the
enforcement of its rights and remedies under the Loan Agreement and/or any other
Loan Document, which the Guarantor agrees constitute for all purposes hereunder
"Guaranteed Obligations") . All amounts so received by the Lender (and all
investments of such amounts and earnings and proceeds of such investments) shall
be held by the Lender in a cash collateral account in the name of the Lender
entitled "IMS Health/Synavant Cash Collateral Account" (the "CASH COLLATERAL
ACCOUNT") as collateral for the prompt payment of such Guaranteed Obligations.
At the Lender's request, the Guarantor hereby agrees to enter into such
agreement or agreements in connection with the establishment of the Cash
Collateral Account and the perfection of the Lender's security interest therein.
The Lender may, but shall be under no obligation to, pursue any rights and
remedies available to the Lender under the Loan Agreement and at law or in
equity against the Borrower as it deems necessary or desirable and only for such
period of time as it shall decide in its sole discretion. If the Borrower has
not paid the full amount of the Guaranteed Obligations to the Lender in cash
within a period of time deemed reasonable by the Lender after demand by the
Lender, the Guarantor hereby authorizes the Lender to apply the proceeds in the
Cash Collateral Account to the repayment of all Guaranteed Obligations. If the
proceeds in the Cash Collateral Account shall be insufficient to repay the
amount of the Guaranteed Obligations in full in cash, the Guarantor hereby
agrees to pay an amount equal to such shortfall to the Lender immediately upon
demand. The Guarantor waives any right or defense to this Guarantee that it may
have as a result of the type of action, if any, that the Lender takes to collect
the Guaranteed Obligations from the Borrower and the determination by the Lender
of how long to proceed against the Borrower before using the proceeds in the
Cash

                                      B-3
<PAGE>

Collateral Account to repay the Guaranteed Obligations, and acknowledges and
agrees that it is estopped from objecting to any such action (or inaction, as
the case may be) on any grounds. The Guarantor further agrees that,
notwithstanding this Section 6(b), this Guarantee remains a guaranty of payment
and not of collection.

            SECTION 7. INFORMATION. The Guarantor assumes all responsibility for
being and keeping itself informed of the Borrower's financial condition and
assets, and of all other circumstances bearing upon the risk of nonpayment of
the Guaranteed Obligations and the nature, scope and extent of the risks that
the Guarantor assumes and incurs hereunder, and agrees that the Lender will not
have any duty to advise it of information known to it regarding such
circumstances or risks.

            SECTION 8. REPRESENTATIONS AND WARRANTIES. The Guarantor hereby
represents and warrants to the Lender that:

            (a) The Guarantor is a corporation duly organized, validly existing
and in good standing under the laws of its jurisdiction of incorporation, has
all requisite power and authority, and the legal right, to own, operate and
lease its properties and to carry on the business in which it is engaged or
presently proposes to engage, and is duly qualified where it is required to be
so qualified or licensed except where a failure to be so qualified would not
cause a material adverse change in financial condition, operations, assets,
business, properties or prospects of the Guarantor, and in compliance with all
Requirements of Law except to the extent that failure to comply therewith could
not, in the aggregate, cause a material adverse change in the financial
condition, operations, assets, business, properties or prospects of the
Guarantor.

            (b) The Guarantor has all requisite power and authority to execute,
deliver and perform this Guarantee. The Guarantor has taken all necessary
corporate and legal action to authorize the execution and delivery and
performance of this Guarantee. This Guarantee has been executed and delivered by
a duly authorized representative of the Guarantor, and this Guarantee
constitutes the legal, valid and binding obligation of the Guarantor,
enforceable against it in accordance with its terms, except as enforceability
may be limited by bankruptcy, insolvency, moratorium, reorganization or other
similar laws affecting creditors' rights generally and except as enforceability
may be limited by general principles of equity and an implied covenant of good
faith.

            (c) The execution, delivery and performance of this Guarantee by the
Guarantor (i) do not require any consent or approval of, registration or filing
with, or any action by, any governmental authority, except those as have been
obtained or made and are in full force and effect or where the failure to do so,
individually or in the aggregate, could not reasonably be expected to have a
material adverse effect upon its financial condition, business, properties or
prospects, (ii) will not violate any provision of any existing law, treaty or
regulation or of any order, judgment, award or decree of any court, arbitrator,
Governmental Authority or any Requirement of Law or Contractual Obligation
applicable to the Guarantor and will not result in the creation or imposition of
any Lien on any of the material properties or assets of the Guarantor pursuant
to the provisions of any such Requirement of Law or Contractual Obligation.

                                      B-4
<PAGE>

            (d) On and as of the Effective Date, both before and after giving
effect to the transactions contemplated by the Distribution Agreement and this
Guarantee, the Guarantor (i) is and will be Solvent (as defined in the following
sentence), (ii) is and will continue to be able to pay its debts as they mature,
and (iii) has and will continue to have capital sufficient (and will not be left
with unreasonably small capital) to conduct its business and all businesses in
which it is engaged. "SOLVENT" means that (x) the Guarantor will have assets
with a present fair saleable valuegreater than the amount of its total
liabilities (including contingent liabilities), (y) the sum of the Guarantor's
assets at book value exceeds the sum of its debts, and (z) on the Guarantor's
most recent balance sheet, the sum of its assets exceeds the sum of its
liabilities.

            (e) All representations and warranties in the current letter
agreement dated March 2, 2000 between the Guarantor and the Lender in connection
with the $75,000,000 revolving credit facility (the "EXISTING LOAN AGREEMENT")
are true and correct in all material respects as of the date hereof (except to
the extent any such representation or warranty is expressly made as of a prior
date).

            (f) No "Event of Default" or "Unmatured Event of Default" (each as
defined in the Existing Loan Agreement) exists under the Existing Loan
Agreement.

            SECTION 9. TERMINATION. The guarantees made hereunder (a) shall
terminate when all the Guaranteed Obligations have been paid in full in cash,
and the Lender has no further commitment to lend under the Loan Agreement and
(b) shall continue to be effective or be reinstated, as the case may be, if at
any time payment, or any part thereof, of any Guaranteed Obligation is rescinded
or must otherwise be restored by the Lender or the Guarantor upon the bankruptcy
or reorganization of the Borrower, the Guarantor or otherwise. In connection
with the foregoing, the Lender shall execute and deliver to the Guarantor or the
Guarantor's designee, at the Guarantor's expense, any documents or instruments
which the Guarantor shall reasonably request from time to time to evidence such
termination and release.

            SECTION 10. BINDING EFFECT; SEVERAL AGREEMENT; ASSIGNMENTS. Whenever
in this Guarantee any of the parties hereto is referred to, such reference shall
be deemed to include the successors and assigns of such party; and all
covenants, promises and agreements by or on behalf of the Guarantor that are
contained in this Guarantee shall bind and inure to the benefit of each party
hereto and their respective successors and assigns. This Guarantee shall become
effective as to the Guarantor when a counterpart hereof executed on behalf of
the Guarantor shall have been delivered to the Lender, and a counterpart hereof
shall have been executed on behalf of the Lender, and thereafter shall be
binding upon the Guarantor and the Lender and their respective successors and
assigns, and shall inure to the benefit of the Guarantor, the Lender, and their
respective successors and assigns, except that the Guarantor shall not have the
right to assign its rights or obligations hereunder or any interest herein (and
any such attempted assignment shall be void).

                                      B-5
<PAGE>

            SECTION 11.  WAIVERS; AMENDMENT.

            (a) No failure or delay of the Lender of any in exercising any power
or right hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Lender hereunder are cumulative and are not exclusive of any
rights or remedies that it would otherwise have. No waiver of any provision of
this Guarantee or consent to any departure by the Guarantor therefrom shall in
any event be effective unless the same shall be permitted by paragraph (b)
below, and then such waiver and consent shall be effective only in the specific
instance and for the purpose for which given. No notice or demand on the
Guarantor in any case shall entitle the Guarantor to any other or further notice
in similar or other circumstances.

            (b) Neither this Guarantee nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Guarantor and the Lender.

            SECTION 12. GOVERNING LAW. THIS GUARANTEE SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA (WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICTS OF LAW).

            SECTION 13. NOTICES. All communications and notices hereunder shall
be in writing (including telecopier or similar writing, but not e-mail) and
shall be given to such party at its address or telecopier number set forth on
the signature pages hereof or such other address or telecopier number as such
party may hereafter specify for the purpose of notice to such other party. Each
such notice, request or other communication shall be effective (i) if given by
telecopier, when such telecopy is transmitted to the telecopier number specified
in this Section and the information is received, (ii) if given by mail, 3
Domestic Business Days after such communication is deposited in the mail with
first class postage prepaid, addressed as aforesaid or (iii) if given by any
other means, when delivered at the address specified in this Section.

            SECTION 14.  SURVIVAL OF GUARANTEE; SEVERABILITY.

            (a) All covenants, agreements, representations and warranties made
by the Guarantor herein and in the certificates or other instruments prepared or
delivered in connection with or pursuant to this Guarantee shall be considered
to have been relied upon by the Lender and shall survive the making by the
Lender of any Loans or FX Contracts pursuant to the Loan Agreement regardless of
any investigation made by the Lender or on its behalf, and shall continue in
full force and effect as long as the principal of or any accrued interest on any
Loan, any amount due under any FX Contract or any other fee or amount payable
under this Guarantee is outstanding and unpaid and as long as the Facility has
not been terminated.

                                      B-6
<PAGE>

            (b) In the event one or more of the provisions contained in this
Guarantee, in the Loan Agreement or in any other document related thereto should
be held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby (it being understood that
the invalidity of a particular provision in a particular jurisdiction shall not
in and of itself affect the validity of such provision in any other
jurisdiction). The parties shall endeavor in good-faith negotiations to replace
the invalid, illegal or unenforceable provisions with valid provisions the
economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

            SECTION 15. COUNTERPARTS. This Guarantee may be executed in
counterparts, each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. Delivery of an executed
signature page to this Guarantee by facsimile transmission shall be as effective
as delivery of a manually executed counterpart of this Guarantee.

            SECTION 16. JURISDICTION; CONSENT TO SERVICE OF PROCESS.

            (a) The Guarantor hereby irrevocably and unconditionally submits,
for itself and its property, to the nonexclusive jurisdiction of any Georgia
state court or Federal court of the United States of America sitting in Atlanta,
Georgia, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Guarantee or any other documents in
connection therewith, or for recognition or enforcement of any judgment, and
each of the parties hereto hereby irrevocably and unconditionally agrees that
all claims in respect of any such action or proceeding may be heard and
determined in such Georgia state court or, to the extent permitted by law, in
such Federal court. Each of the parties hereto agrees that a final judgment in
any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Guarantee shall affect any right that the Lender may otherwise
have to bring any action or proceeding relating to this Guarantee or the other
documents executed and delivered in connection therewith against the Guarantor
or its properties in the courts of any jurisdiction.

            (b) The Guarantor hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection that it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Guarantee in any Georgia state or
Federal court. Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

            (c) Each party to this Guarantee irrevocably consents to service of
process in the manner provided for notices in Section 13. Nothing in this
Guarantee will affect the right of any party to this Guarantee to serve process
in any other manner permitted by law.

            SECTION 17. WAIVER OF JURY TRIAL. THE GUARANTOR HERBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY

                                      B-7
<PAGE>

HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY
ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS GUARANTEE.

            SECTION 18. RIGHT OF SETOFF. If an Event of Default shall have
occurred and be continuing, the Lender is hereby authorized at any time and from
time to time, to the fullest extent permitted by law, to set off and apply any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other Indebtedness at any time owing by the Lender to or for
the credit or the account of the Guarantor against any or all the obligations of
the Guarantor now or hereafter existing under this Guarantee held by the Lender,
irrespective of whether or not the Lender shall have made any demand under this
Guarantee or any other Loan Document and although such obligations may be
unmatured. The rights of the Lender under this Section 18 are in addition to
other rights and remedies (including other rights of setoff) which the Lender
may have.

Mr. Craig S. Kussman
Executive Vice President and Chief Financial Officer
Synavant, Inc.

Dear Mr. Kussman:

IMS Health Incorporated (IMS) shall support the working capital requirements of
the Synavant Business (such business as described in the Form 10 and the related
Synavant combined financial statements). Heretofore the Synavant Business has
been operating under IMS and has been receiving financing from IMS, where
required, for its operating needs. To expedite the Distribution, IMS shall
ensure that Synavant Inc. will have a line of credit from a major bank or
financial institution in place on the Distribution Date. This line of credit
will be supported by IMS in connection with the Distribution in an amount not to
exceed $30 million and, along with existing cash, financial resources and the
working capital adjustment on the Distribution Date (such date as defined in the
Form 10), will be sufficient for Synavant to execute its operations and short
term business plan. Subject to the foregoing, we shall provide credit support
sufficient to meet the working capital needs of Synavant for up to one year from
the Distribution Date (the "Anniversary Date") if necessary, PROVIDED HOWEVER,
that at such time as Synavant has secured an independent line of credit during
the one year post-Distribution period that matures beyond the Anniversary Date
without IMS credit support and which satisfies the foregoing criteria, IMS'
credit support commitment shall immediately terminate.

James C. Malone
Chief Financial Officer
IMS Health, Inc.
