IMS HEALTH INCORPORATED
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS-(UNAUDITED)
(AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)


NOTE 1. INTERIM CONSOLIDATED FINANCIAL STATEMENTS

         The accompanying unaudited Condensed Consolidated Financial Statements
have been prepared in accordance with accounting principles generally accepted
in the United States of America for interim financial information and Article 10
of Regulation S-X under the Securities and Exchange Act of 1934, as amended. The
Condensed Consolidated Financial Statements and related notes should be read in
conjunction with the consolidated financial statements and related notes of IMS
Health Incorporated (the "Company" or "IMS") included in its 2001 Annual Report
on Form 10-K. Accordingly, the accompanying Condensed Consolidated Financial
Statements do not include all the information and notes required by accounting
principles generally accepted in the United States of America for complete
financial statements. In the opinion of management, all adjustments, all of
which are of a normal recurring nature, considered necessary for a fair
presentation of financial position, results of operations and cash flows for the
periods presented have been included. The results of operations for interim
periods are not necessarily indicative of the results expected for the full
year.

NOTE 2. BASIS OF PRESENTATION

         IMS is a leading global provider of information solutions to the
pharmaceutical and healthcare industries. IMS operates in more than 100
countries and consists of the following businesses:

     o   IMS is a leading global provider of market information, sales
         management and decision-support services to the pharmaceutical and
         healthcare industries. Its key products include sales management
         information to optimize sales force productivity, marketing
         effectiveness research for prescription and over-the-counter
         pharmaceutical products, consulting and other services. IMS also owns
         a venture capital entity, Enterprise Associates, LLC ("Enterprises")
         which is focused on investments in emerging businesses, and a 26.7%
         equity interest in The TriZetto Group, Inc. ("TriZetto").

     o   Cognizant Technology Solutions Corporation ("CTS") delivers full
         life-cycle solutions to complex software development and maintenance
         problems that companies face as they transition to e-business. These
         services are delivered through the use of a seamless on-site and
         offshore consulting project team. CTS's primary service offerings
         include application development and integration, application
         management and re-engineering services. CTS is a publicly traded
         corporation on the Nasdaq national market system. IMS owned 58.2% of
         the common shares outstanding of CTS (93.3% of the outstanding voting
         power) as of March 31, 2002 and 58.3% as of December 31, 2001 (93.3%
         of the outstanding voting power). IMS accounts for CTS as a
         consolidated subsidiary.

         On July 26, 1999, the Company completed a spin-off of the majority of
its equity investment in Gartner, Inc. ("Gartner", formerly known as "Gartner
Group Inc.") to the Company's shareholders (the "Gartner Spin-Off"). The
Consolidated Financial Statements of the Company have been reclassified for all
periods presented to reflect the Gartner equity investment as a discontinued
operation. The Company sold its remaining interest in Gartner during the third
quarter of 2001.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS-(UNAUDITED)
(AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)


NOTE 3.  ACQUISITIONS AND DISPOSITIONS

         During the first quarter of 2002, the Company acquired Infoplex Durdaut
& Jassmann GmbH, based in Germany. The purchase price for this acquisition,
including direct and incremental transaction costs, amounted to $7,013, payable
in cash. After an allocation of the purchase price to the net assets acquired,
the Company recorded goodwill of $3,758. Had this acquisition occurred as of
January 1, 2002 or 2001, the impact on the Company's results of operations would
not have been material.

         During the first quarter of 2001, the Company exercised its option to
purchase the remaining interest in Medicare Audits Limited ("Medicare"), a U.K.
based hospital research firm, for a net cash payment of $7,889. After the final
allocation of the purchase price to the net assets acquired, goodwill of $7,921
was recorded.

         In addition, during the first quarter of 2001, the Company recorded
$1,400 of pre-tax net gains. This includes a gain of $1,990 resulting from the
sale of IDRAC Holdings Inc. ("IDRAC"), a non-strategic property, which provides
information on pharmaceutical product registrations. The operating results of
IDRAC were not significant to the results of operations of the Company.

         In a separate transaction, the Company also granted a non-exclusive
perpetual license to IHI to use certain data for aggregate cash consideration of
$17,000, of which approximately $7,900 was recognized as revenue in the first
quarter of 2001 and $9,100 was deferred as of March 31, 2001 because the
required revenue recognition criteria had not been met as of that date.

NOTE 4. GOODWILL AND INTANGIBLE ASSETS

         Effective January 1, 2002, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 142, "Goodwill and Other Intangible Assets"
("SFAS No. 142"). SFAS No. 142 addresses the initial recognition and measurement
of intangible assets acquired outside of a business combination and the
accounting for goodwill and other intangible assets subsequent to their
acquisition. SFAS No. 142 provides that goodwill and intangible assets which
have indefinite useful lives will not be amortized but rather will be tested at
least annually for impairment. It also provides that intangible assets that have
finite useful lives be amortized. There was no impairment of goodwill upon
adoption of SFAS No. 142 and as such, the Company did not recognize a transition
adjustment during the first quarter of 2002.

         During the three months ended March 31, 2002, the Company recorded
additional goodwill of $3,758. As of March 31, 2002, goodwill was $153,665 at
the IMS Segment and $878 at the CTS Segment.

         All of the Company's acquired intangibles are subject to amortization.
The Company did not acquire any intangible assets during the three months ended
March 31, 2002. Intangible asset amortization expense was $530 during the first
quarter of 2002. At March 31, 2002, intangible assets were composed of Customer
Relationships and Trade Names. The gross carrying amounts and related
accumulated amortization of Customer Relationships and Trade Names were $15,850
and $394 and $2,680 and $134, respectively, at March 31, 2002.

         Amortization expense associated with intangible assets at March 31,
2002 is estimated to be $1,591 for the last three quarters of 2002 and $2,121
for each year during 2003 through 2006.

NOTE 6. CONTINGENCIES

         The Company and its subsidiaries are involved in various legal
proceedings, claims litigation and tax matters arising in the ordinary course of
business. In the opinion of management, the outcome of such current legal
proceedings, claims litigation and tax matters, if decided adversely, could have
a material effect on quarterly or annual operating results or cash flows when
resolved in a future period. However, in the opinion of management, these
matters will not materially affect the Company's consolidated financial
position.

         In addition, the Company is subject to certain other contingencies
discussed below:

INFORMATION RESOURCES LITIGATION

         On July 29, 1996, Information Resources, Inc. ("IRI") filed a complaint
in the United States District Court for the Southern District of New York,
naming as defendants the corporation then known as "The Dun and Bradstreet
Corporation" and now known as "R. H. Donnelley Corporation" ("Donnelley"), A.C.
Nielsen Company and I.M.S. International Inc. (a predecessor of IMS) (the "IRI
Action"). At the time of the filing of the complaint, each of the other
defendants was a subsidiary of Donnelley.

         The complaint alleges various violations of the antitrust laws of the
United States, including alleged violations of Sections 1 and 2 of the Sherman
Act. The complaint also alleges a claim of tortuous interference with a contract
and a claim of tortuous interference with a prospective business relationship.
These latter claims relate to the acquisition by the defendants of Survey
Research Group Limited ("SRG"). IRI alleges that SRG violated an alleged
agreement with IRI when it agreed to be acquired by the defendants and that the
defendants induced SRG to breach that agreement. IRI's complaint alleges damages
in excess of $350,000, which amount IRI has asked to be trebled under the
antitrust laws. IRI also seeks punitive damages in an unspecified amount.

         In light of the potentially significant liabilities which could arise
from the IRI Action and in order to facilitate the distribution by Donnelley of
shares of Cognizant Corporation ("Cognizant") and


                                       9

(AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

ACNielsen Corporation (the parent company of A.C. Nielsen Company) in 1996,
Donnelley, ACNielsen and Cognizant entered into an Indemnity and Joint Defense
Agreement pursuant to which they agreed (i) to certain arrangements allocating
liabilities that may arise out of or in connection with the IRI Action, and (ii)
to conduct a joint defense of such action. In particular, the Indemnity and
Joint Defense Agreement provides that, in the event of an adverse decision,
ACNielsen will assume exclusive liability for liabilities up to a maximum amount
to be calculated at the time such liabilities, if any, become payable (the "ACN
Maximum Amount") and that Cognizant and Donnelley will share liability equally
for any amounts in excess of the ACN Maximum Amount. The ACN Maximum Amount will
be determined by an investment banking firm as the maximum amount ACNielsen will
be able to pay after giving effect to (i) any plan submitted by such investment
bank that is designed to maximize the claims paying ability of ACNielsen without
impairing the investment banking firm's ability to deliver a viability opinion
(but which will not require any action requiring shareholder approval), and (ii)
payment of related fees and expenses. For these purposes, financial viability
means the ability of ACNielsen, after giving effect to such plan, the payment of
related fees and expenses and the payment of the ACN Maximum Amount, to pay its
debts as they become due and to finance the current and anticipated operating
and capital requirements of its business, as reconstituted by such plan, for two
years from the date any such plan is expected to be implemented. On February 19,
2001, ACNielsen announced that it merged with VNU N.V. Pursuant to the Indemnity
and Joint Defense Agreement, VNU is to be included with ACNielsen for purposes
of determining the ACN Maximum Amount.

         In 1998, IMS was spun-off from Cognizant (the "1998 Spin-Off"), which
then changed its name to Nielsen Media Research, Inc. ("NMR"). IMS and NMR are
jointly and severally liable to Donnelley and ACNielsen for Cognizant's
obligations under the terms of the Distribution Agreement dated October 28, 1996
among Donnelley, Cognizant and ACNielsen (the "1996 Distribution Agreement"). In
connection with the 1998 Spin-Off, IMS and NMR agreed that, as between
themselves, IMS will assume 75%, and NMR will assume 25%, of any payments to be
made in respect of the IRI Action under the Indemnity and Joint Defense
Agreement or otherwise, including any legal fees and expenses related thereto
incurred in 1999 or thereafter. IMS agreed to be fully responsible for any legal
fees and expenses incurred during 1998. NMR's aggregate liability to IMS for
payments in respect of the IRI Action and certain other contingent liabilities
shall not exceed $125,000.

         During 1998, Donnelley separated into two companies (the "1998
Donnelley Spin"), Donnelley and The Dun & Bradstreet Corporation ("D&B I"). As a
result, Donnelley and D&B I are each jointly and severally liable for all
Donnelley liabilities under the Indemnity and Joint Defense Agreement and the
1996 Distribution Agreement. During 2000, D&B I separated into two companies,
Moody's Corporation ("Moody's") and The Dun & Bradstreet Corporation ("D&B II").
Moody's and D&B II are each jointly and severally liable for all liabilities
under the Indemnity and Joint Defense Agreement and the 1996 Distribution
Agreement that were assumed by D&B I in the 1998 Donnelley Spin.

         Management of the Company is unable to predict at this time the final
outcome of this matter or whether the resolution of this matter could materially
affect the Company's results of operations, cash flows or financial position.

MATTERS BEFORE THE EUROPEAN COMMISSION

         The Company is the subject of complaints filed with the European
Commission ("EC" or the "Commission") pursuant to Article 3 of Council
Regulation No. 17 of 1972. The EC complaints allege that the Company has been
and continues to engage in certain commercial practices that violate Articles 81
and 82 of the EC Treaty, which relate to agreements or abuses of a dominant
position that adversely affect competition.

         As a result of certain of these complaints, on October 19, 2000, the
Commission initiated formal proceedings against the Company through the adoption
of a statement of objections alleging that certain of the Company's commercial
practices constituted an abuse of a dominant position in contravention of
Article 82 of the EC Treaty. A statement of objections is a preliminary document
that does not represent the Commission's final view on the practices at issue.
Under Commission procedures, the Company has full rights of defense, including
access to the Commission's files, the right to answer the statement of
objections in writing and produce evidence of its own, and the right to request
the opportunity to present its defense at an oral hearing. On February 6, 2001,
the Company filed its written answer to the statement of objections. The
Commission will ultimately determine whether a decision requiring the Company to
end some or all of the contested practices is necessary and may impose fines
against the Company. If such a decision is rendered against the Company, the
Company could appeal that decision before the European Court of First Instance.
The Company intends to vigorously defend this matter.

         One of the EC complaints is an application lodged with the Commission
by National Data Corporation ("NDC") on December 19, 2000. This complaint
requests that the Commission initiate a proceeding against the Company for an
alleged infringement of Article 82 of the EC Treaty and grant interim measures
(the "Application"). The Application concerns an IMS geographic mapping
structure used for the reporting of regional sales data in Germany, which the
German courts have ruled is copyright protected. The Application requests that
the Commission grant interim relief requiring the Company to grant NDC a
compulsory license to enable NDC to use this structure in its competing regional
sales data service in Germany.

         On March 8, 2001, the Commission decided to initiate formal proceedings
against the Company through the adoption of another statement of objections
alleging that the Company's refusal to enter into negotiations with NDC
following NDC's request for a license to use the aforementioned geographic
mapping structure could constitute an abuse of a dominant position in
contravention of Article 82 of the EC Treaty. In addition, the Commission
proposed the granting of interim measures requiring the Company to license this
structure to third parties, including NDC, until the Commission adopts a final
decision on the merits of the case.

         On July 3, 2001, the Commission announced its interim decision in these
proceedings (the "Interim Decision") ordering interim measures pending a final
decision on the Application. The Interim Decision required the Company to grant
a license of the geographic mapping structure on commercially reasonable terms
without delay to NDC and to any other competitor currently present on the German
regional sales data market should it request a license. The terms and royalties
to be paid for the license were to be agreed between the Company and the
requesting party, and if agreement


                                       11

IMS HEALTH INCORPORATED

(AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

could not be reached in a two week period, then the terms and royalties for the
license would be determined by one or more independent experts agreed to by the
parties, or if the parties could not agree, then the Commission would appoint
one or more experts. The Interim Decision states that the expert(s) shall
communicate its determination to the Commission for approval within two weeks of
being chosen. Finally, the Interim Decision provides for a penalty of 1,000
Euros per day should the Company fail to comply with the Interim Decision.

         Following issuance of the Interim Decision, NDC and AzyX Deutschland
GmbH ("AzyX") requested from the Company a license to the geographic mapping
structure. The Company was not able to agree with NDC or AzyX on the terms and
royalties to be paid for the license or the determination of one or more
independent experts. Before the Commission appointed any independent experts,
the Interim Decision was suspended by the President of the European Court of
First Instance (the "CFI") as noted below.

         On August 6, 2001, the Company filed an appeal with the CFI seeking the
annulment of the Interim Decision in its entirety (the "Annulment Appeal") and
requesting that operation of the Interim Decision be suspended until the CFI
renders judgement on the Annulment Appeal. On October 26, 2001, the President of
the CFI ruled in the Company's favor and suspended the operation of the Decision
until the Annulment Appeal is heard and decided. On December 12, 2001, NDC filed
an appeal to the European Court of Justice ("ECJ") seeking annulment of the
October 26 decision against it. On April 11, 2002, the ECJ denied NDC's appeal.
The Company intends to continue to vigorously assert that its refusal to grant
licenses for the use of its copyright-protected geographic mapping structure to
its direct competitors in Germany, which compete in the same market for which
the copyright exists, is not in contravention of Article 82 of the EC Treaty.

         Management of the Company is unable to predict at this time the final
outcome of the matters described above or whether the resolution of these
matters could materially affect the Company's future results of operations, cash
flows or financial position.

OTHER CONTINGENCIES

         Under the terms of the purchase agreements related to acquisitions made
in 2001, the Company may be required to pay up to $36,720 in relation to 2002 to
2004 as contingent consideration. Of the contingent consideration, up to $13,760
will be recorded as additional goodwill, while up to $22,960 will be recorded as
compensation as earned in accordance with the provisions of Emerging Issues Task
Force ("EITF") Statement No. 95-8, "Accounting for Contingent Consideration Paid
to the Shareholders of an Acquired Enterprise in a Purchase Business
Combination." The maximum contingent consideration payable with respect to any
given year in the earn out period is $12,420. As of March 31, 2002, no accrual
has been recorded as the contingency has not been resolved. The annual
contingent payments will be resolved at the end of each respective calendar year
from 2002 through 2004.

         The Company and its predecessors have entered, and the Company
continues to enter, into global tax planning initiatives in the normal course of
their businesses. These activities are subject to review by applicable tax
authorities. As a result of the review process, uncertainties exist and it is
possible that some of these matters could be resolved adversely to the Company.

(AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

         In 1999, the Company was informed by D&B I, acting as agent for
Donnelley, that the IRS was reviewing Donnelley's utilization of certain capital
losses during 1989 and 1990. In response, D&B I advised that it intended to file
an amended tax return for these periods and to pay this amount in order to
prevent further interest from accruing. In May 2000, D&B I paid $349,291 of this
amount and the Company paid $212,291 pursuant to its obligation under the 1996
Distribution Agreement and the Distribution Agreement between Cognizant (renamed
NMR) and the Company (the "1998 Distribution Agreement"), whereby the Company is
in effect obligated to pay an amount equal to one-half of the tax and interest
owed to the IRS for this matter to the extent the liability exceeds $137,000
(subject to reimbursement to the Company of a portion of this amount by NMR). In
the second quarter of 2000, Donnelley received a formal assessment from the IRS
with respect to this matter in the amount of $561,582, for additional tax and
interest due, which was satisfied by the payments made by D&B I and the Company
in May 2000. D&B I has advised the Company that, notwithstanding the filing and
payment, it intends to contest the assessment and would also contest the
assessment of amounts, if any, in excess of the amounts paid. The Company had
previously accrued for this liability and, therefore, this payment did not
result in an expense in 2000.

         Pursuant to the 1998 Distribution Agreement, NMR is responsible for a
portion of the amount that the Company paid pursuant to the 1996 Distribution
Agreement ($41,136 according to the Company's calculations). NMR was not
obligated to pay its share to the Company until January 2, 2001. In December
2000, the Company requested reimbursement of this amount from NMR. On January 2,
2001, NMR made a payment of $10,530 in respect of such matter but refused to pay
the remaining $30,606 based on its interpretation of the applicable agreements.
The Company believes that NMR's position has no merit and plainly contravenes
the terms of the applicable agreements. Accordingly, the Company has a
receivable of $34,050 which includes the outstanding principal and accumulated
accrued interest income of $3,444. During the three months ended March 31, 2002,
$689 of interest income was accrued in accordance with the terms of the
applicable agreements. These amounts are reflected in other receivables in the
Consolidated Statements of Financial Position. The Company has commenced
arbitration regarding this matter by filing a Demand for Arbitration with the
American Arbitration Association International Center for Dispute Resolution.
The Company believes it will prevail in this matter, and it intends to
vigorously pursue it.

         In connection with the Gartner Spin-Off, the Company and Gartner
entered into a Distribution Agreement and an Agreement and Plan of Merger
(together, the "1999 Distribution Agreements"). Pursuant to the 1999
Distribution Agreements, Gartner agreed to indemnify the Company and its
stockholders for additional taxes which may become payable as a result of
certain actions that may be taken by Gartner that adversely affect the tax-free
treatment of the Gartner Spin-Off. However, the Company may become obligated for
certain tax liabilities in the event the Gartner Spin-Off is deemed to be a
taxable transaction as a result of certain Gartner share transactions that may
be undertaken following the Gartner Spin-Off. In the opinion of management, it
is not probable that any material liabilities will be incurred by the Company
with respect to this matter.

         As part of the Synavant Spin-Off, IMS and Synavant entered into a
Distribution Agreement (the "Synavant Distribution Agreement"). In connection
with the distribution, Synavant will be jointly and severally liable to the
other parties in the 1996 and 1998 Distribution Agreements for the liabilities
relating to certain tax matters as well as those relating to the IRI Action.
Under the Synavant


                                       13

IMS HEALTH INCORPORATED
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS-(UNAUDITED)
(AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

Distribution Agreement, as between IMS and Synavant, each will bear 50% of IMS's
share of these liabilities (net of the liability borne by NMR), up to a maximum
liability of $9,000 for Synavant. If, contrary to expectations, the Synavant
Spin-Off were not to qualify as tax free under Section 355 of the Internal
Revenue Code, then, in general, a corporate tax would be payable by the
consolidated group, of which IMS is a common parent and Synavant is a member,
based on the difference between (x) the fair market value of the Synavant Common
Stock on the date of the Synavant Spin-Off and (y) the adjusted basis of such
Synavant Common Stock. In addition, under the consolidated return rules, each
member of the consolidated group would be severally liable for such tax
liability. IMS estimates that the aggregate tax liability in this regard is not
expected to exceed $100,000. Pursuant to the Tax Allocation Agreement, IMS would
be liable for the resulting corporate tax, except as provided in the Synavant
Distribution Agreement. In the opinion of management and based on the opinion of
tax counsel, it is not probable that the Company will incur any liability.

         The Company is unable to predict at this time the final outcome of
these matters described above or whether the resolution of these matters could
materially affect the Company's results of operations, cash flows, or financial
position.

NOTE 7. FINANCIAL INSTRUMENTS

FOREIGN EXCHANGE RISK MANAGEMENT

         On January 1, 2001, the Company adopted SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities" and SFAS No. 138, "Accounting for
Certain Derivative Instruments and Certain Hedging Activities, an amendment of
SFAS No. 133." These statements standardize the accounting for derivative
instruments. The Company is required to record all derivative instruments on the
balance sheet at fair value. Derivatives that are not classified as hedges are
adjusted to fair value through earnings. Changes in fair value of the
derivatives that the Company has designated and that qualify as effective hedges
are recorded in either other comprehensive income or earnings. Any ineffective
portion of the Company's derivatives that are classified as hedges is
immediately recognized in earnings. This change in accounting principle did not
have a material impact on the Company's financial position, results of
operations or cash flow at the date of adoption.

         The Company transacts business in more than 100 countries and is
subject to risks associated with changing foreign exchange rates. The Company's
objective is to reduce earnings and cash flow volatility associated with foreign
exchange rate changes. Accordingly, the Company enters into foreign currency
forward contracts to minimize the impact of foreign exchange movements on net
income and on the value of non-functional currency assets and liabilities.

         It is the Company's policy to enter into foreign currency transactions
only to the extent necessary to meet its objectives as stated above. The Company
does not enter into foreign currency transactions for investment or speculative
purposes. At March 31, 2002, all foreign currency forward contracts had a term
of less than one year. The principal currencies hedged are the Japanese yen, the
Euro, the Swiss franc, the Canadian dollar and the British pound sterling.

         The impact of foreign exchange risk management activities on pre-tax
income during the three months ended March 31, 2002 and 2001 resulted in a net
gain of $2,268 and $1,397, respectively. At March 31, 2002, the Company had
approximately $298,000 in foreign exchange forward contracts


                                       14

(AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

outstanding with expiration dates through June 2002 hedging non-functional
currency assets and liabilities. Gains and losses on these contracts are
included in the Consolidated Statements of Income in Other expense, net.

FAIR VALUE OF FINANCIAL INSTRUMENTS

         At March 31, 2002, the Company's financial instruments included cash,
cash equivalents, receivables, accounts payable, short-term debt, including
short-term borrowings reclassified as long-term debt, and foreign currency
forward contracts. Due to their short-term nature, the fair value of these
instruments approximated their carrying value at March 31, 2002. At March 31,
2002, the fair value of the Company's foreign currency forward contracts was
$298,000 and all contracts mature in 2002. The fair values of the forward
contracts were estimated based on quoted market prices.

CREDIT CONCENTRATIONS

         The Company continually monitors its positions with, and the credit
quality of, the financial institutions that are counter parties to its financial
instruments and does not anticipate non-performance by the counter parties. The
Company would not realize a material loss as of March 31, 2002 in the event of
non-performance by any one counterparty. The Company enters into transactions
only with high credit quality financial institution counter parties. In
addition, the Company limits the amount of credit exposure with any one
institution.

         The Company maintains accounts receivable balances of $267,264 and
$228,626, net of allowances for doubtful accounts, at March 31, 2002 and
December 31, 2001, respectively, principally from customers in the
pharmaceutical industry. The Company's trade receivables do not represent
significant concentrations of credit risk at March 31, 2002, due to the high
quality of its customers and their dispersion across many geographic areas.

LINES OF CREDIT AND LIQUIDITY

         The Company has borrowing arrangements with several international banks
to provide short and long-term lines of credit up to $525,000. Total borrowings
under these lines were $457,544 and $346,463 at March 31, 2002 and December 31,
2001, respectively. In general, the terms of these lines of credit give the
Company the option to borrow at an interest rate equal to LIBOR plus 37.5 basis
points for short-term lines and LIBOR plus 65 basis points for long-term lines.
The weighted average interest rates for the short-term lines were 2.33% and
2.34% at March 31, 2002 and December 31, 2001, respectively. The weighted
average interest rates for the long-term lines were 3.02% at March 31, 2002. The
commitment fee associated with the unused short-term lines of credit is 22.5
basis points per year, increasing to 28.75 basis points per year if the
facilities are less than 50% utilized. Under the long-term lines the commitment
fee is 52.5 basis points per year. The borrowing arrangements require the
Company to comply with certain financial covenants and at March 31, 2002 and
December 31, 2001, the Company was in compliance with all such covenants.

         During the fourth quarter of 2001, the Company renegotiated with
several banks and entered into three-year lines of credit for borrowings of up
to $175,000. Borrowings under these three-year facilities are short-term in
nature; however, the Company has the ability and the intent to refinance the

short-term borrowings through December 2004 as they come due under existing
long-term lines. As such, at March 31, 2002, the Company reclassified $175,000
of its then outstanding debt as long-term debt pursuant to the provisions of
SFAS No. 6, "Classification of Short-Term Obligations Expected to be
Refinanced." Borrowings under short-term lines were $282,544 and $196,463 at
March 31, 2002 and December 31, 2001, respectively. Borrowings have maturity
dates of up to ninety days from their inception.

         In March 2002, the Company entered into interest rate swaps on a
portion of its variable rate debt portfolio. These arrangements convert the
variable interest rates to a fixed interest rate on a notional amount of $50,000
and mature in March 2005. At March 31, 2002, the fixed rates range from 4.05% to
4.51%. Based on interest rates for similar transactions at March 31, 2002, the
fair value of all interest rate swap agreements is not material.

         At March 31, 2002, the Company's Total Current Liabilities exceed
its Total Current Assets by $10,064 primarily as a result of management's
decision to maintain a greater proportion of short-term borrowings versus
longer-term debt instruments. This strategy allows the Company to achieve
lower borrowing costs while providing flexibility to repay debt with cash
flow from operations and proceeds from the exercise of stock options and the
liquidation of equity holdings. Based on estimated future cash flows from
operations, the continued monetization of its investments, the ability to
monetize other assets including its investment in CTS as well as the
Company's ability to utilize existing lines of credit, the Company believes
it will have sufficient cash and other resources to fund its short- and
long-term business plans, including its current and long term obligations,
its contingent payments, its stock repurchase program and its operations.

NOTE 8. INCOME TAXES

         The Company operates in more than 100 countries around the world and
its earnings are taxed at the applicable income tax rate in each of these
countries.

         In the quarter ended March 31, 2002, the Company's tax rate was
impacted by CTS's decision that effective January 1, 2002, pursuant to
Accounting Principles Bulletin No. 23, CTS will no longer provide incremental
U.S. tax on the repatriation of Indian earnings recognized in 2002 and
subsequent periods as these earnings are considered to be permanently reinvested
outside of the United States. During the first quarter of 2002, CTS made a
strategic decision to pursue an international strategy that includes expanded
infrastructure investments in India and geographic expansion in Europe and Asia.
As a component of this strategy, CTS will use 2002 and future Indian earnings to
expand operations outside of the United States instead of repatriating these
earnings to the United States. This change resulted in an effective tax rate for
CTS of 24.5% during the first quarter of 2002, compared to an effective tax rate
for CTS of 37.4% in the first quarter of 2001. Additionally, the Company's
effective tax rate reflects true-ups of current and deferred income tax
liabilities.

         In the quarter ended March 31, 2001, the Company's tax rate was reduced
by approximately $10,200, primarily relating to the recognition of approximately
$11,700 of additional tax benefits arising from a 1998 non-U.S. reorganization
which gave rise to tax deductible amortization of non-U.S. intangible assets.
This change in estimate resulted from the reassessment of the benefits from

this reorganization following certain new non-U.S. tax legislation enacted at
the end of the first quarter of 2001.

         While the Company intends to continue to seek global tax planning
initiatives, there can be no assurance that the Company will be able to
successfully implement such initiatives to reduce or maintain its overall tax
rate.

NOTE 9. IMS HEALTH CAPITAL STOCK

         On July 19, 2000, the Board of Directors authorized a stock repurchase
program to buy up to 40 million shares, marking the fifth consecutive repurchase
program the Company has implemented. Shares acquired through the repurchase
program are open-market purchases in compliance with Securities and Exchange
Commission Rule 10b-18.

         During the first three months of 2002, the Company repurchased
approximately 5.0 million shares of outstanding common stock under this program
at a total cost of $99,707. As of March 31, 2002, approximately 25.6 million
shares had been repurchased since the inception of the program, at a total cost
of $616,884.

         The Company re-issued approximately 0.4 million treasury shares
under option exercises for proceeds of $7,182 during the three months ended
March 31, 2002. In addition, the Company paid dividends of $0.02 per share
for a total of $5,840 during the three months ended March 31, 2002.

payments of approximately $958 against the $6,277 accrual recorded in the fourth
quarter of 2001 as part of this program in accordance with EITF 94-3, "Liability
Recognition of Certain Employee Termination Benefits and Other Costs to Exit an

NOTE 12. OPERATIONS BY BUSINESS SEGMENT

         Operating segments are defined as components of an enterprise about
which financial information is available that is evaluated on a regular basis by
the chief operating decision maker, or decision making groups, in deciding how
to allocate resources to an individual segment and in assessing the performance
of the segment. The Company operates globally and is principally managed by way
of and delivers information, software and related services through, the
strategic business segments referenced below.

         The chief operating decision-makers evaluate performance and allocate
resources based on revenue and operating income data. All inter-segment
transactions are excluded from management's analysis of operations by business
segment.

         At March 31, 2002 and 2001, the Company consisted of the following
segments:

1.   The IMS Segment provides market information, sales management and
     decision-support services to the pharmaceutical and healthcare industries.
     Its key products include sales management information to optimize sales
     force productivity, marketing effectiveness research for prescription and
     over-the-counter pharmaceutical products, consulting and other services.
     The IMS Segment is managed on a global business model with global leaders
     for the majority of its critical business processes. In addition, the IMS
     Segment includes the Company's venture capital unit, Enterprises, which is
     focused on investments in emerging businesses, and IMS's 26.7% equity
     interest in TriZetto.

2.   The CTS Segment delivers full life-cycle solutions to complex software
     development and maintenance problems that companies face as they transition
     to e-business. These services are delivered through the use of a seamless
     on-site and offshore consulting project team. CTS's primary service
     offerings include application development and integration, application
     management and re-engineering services.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

THIS DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE ACCOMPANYING
UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES.

         IMS Health Incorporated ("IMS" or the "Company") is a leading global
provider of information solutions to the pharmaceutical and healthcare
industries. IMS operates in more than 100 countries and consists of the
following business segments:

     o   The IMS Segment is a leading global provider of market information,
         sales management and decision-support services to the pharmaceutical
         and healthcare industries. Its key products include sales management
         information to optimize sales force productivity, marketing
         effectiveness research for prescription and over-the-counter
         pharmaceutical products, consulting and other services. The IMS
         Segment is managed on a global business model with global leaders for
         the majority of its critical business processes. In addition, the IMS
         Segment includes IMS's venture capital unit--Enterprise Associates,
         LLC ("Enterprises"), which is focused on investments in emerging
         businesses, and IMS's 26.7% equity interest in The TriZetto Group,
         Inc. ("TriZetto").

     o   The Cognizant Technology Solutions Corporation ("CTS") Segment
         delivers full life-cycle solutions to complex software development and
         maintenance problems that companies face as they transition to
         e-business. These services are delivered through the use of a seamless
         on-site and offshore consulting project team. CTS's primary service
         offerings include application development and integration, application
         management and re-engineering services. CTS is a publicly traded
         corporation on the NASDAQ national market. IMS owned 58.2% of the
         common shares outstanding (93.3% of the outstanding voting power) as
         of March 31, 2002 and 58.3% as of December 31, 2001. IMS accounts for
         CTS as a consolidated subsidiary.


OPERATING RESULTS

         Revenue for the first quarter of 2002 grew 0.5% to $331,364 from
$329,562 in the first quarter of the prior year. On a constant dollar basis
(i.e., a basis that eliminates currency rate fluctuations), revenue growth was
4.8% in the first quarter. The increase was primarily due to IMS's new products,
expanding consulting business and to several large application management
contracts at CTS.

         IMS's operating costs include data processing costs, the costs of data
collection and production, and costs attributable to personnel involved in
production, data management and the processing and delivery of IMS's services.
IMS's operating costs grew 8.0% to $134,606 in the first quarter of 2002 from
$124,614 in the first quarter of the prior year. The increase resulted primarily
from higher data collection and production costs in the IMS Segment to support
revenue growth.

         Selling and administrative expenses consist primarily of the costs
attributable to sales, marketing, client service and administration, including
personnel, promotion, communications, management, finance and occupancy. IMS's
selling and administrative expenses grew during the first quarter of 2002 to
$91,804 from $89,866 in the first quarter of the prior year. Selling and
administrative expenses grew at only 2.2%, reflecting the results of cost
reduction actions initiated in the fourth quarter of 2001 at the IMS Segment,
and by cost controls at CTS.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

         Depreciation and amortization charges decreased by 26.6% to $13,671 in
the first quarter of 2002 from $18,624 in the first quarter of 2001. The decline
was due primarily to the fact that the Company ceased amortization of goodwill
effective January 1, 2002 in accordance with SFAS No. 142, "Goodwill and Other
Intangible Assets" (see Note 4), and to the impact of the write down of certain
deferred software costs to their net realizable value as part of the Severance,
impairment and other charges recorded in the fourth quarter of 2001.

         Operating income for the first quarter of 2002 declined 5.4% to $91,283
from $96,458 in the first quarter of 2001. Excluding the unfavorable impact of a
generally stronger U.S. dollar, primarily against the Japanese yen and the Euro,
operating income grew 2.1%.

         Net interest expense was $865 in the first quarter of 2002, compared
with $5,071 in the first quarter of the prior year. The expense reduction
resulted primarily from lower interest rates achieved on our borrowings.

         Gains (losses) from investments, net, amounted to a net loss of $1,220
in the first quarter of 2002. The loss in the first quarter of 2002 is due
primarily to losses realized on the sale of investments within IMS's Enterprises
venture capital entity and a write down related to the assessment of
other-than-temporary declines in value of the venture capital investments. The
net gains in the first quarter of 2001 were due primarily to IMS's disposal of
IDRAC Holdings Inc. ("IDRAC"), a non-strategic property providing information on
pharmaceutical product registration, for a gain of $1,990 (see Note 3).

         A $486 gain on the issuance of CTS stock, relating to the exercise of
stock options by CTS employees, was recorded in the first quarter of 2002. This
gain has been recognized in accordance with Staff Accounting Bulletin ("SAB")
No. 51, "Accounting for Sales of Stock by a Subsidiary." A $733 gain in the
first quarter of the prior year resulted from the exercise of stock options by
CTS employees.

         Other expense, net, decreased in the first quarter of 2002 to $3,834
from $6,479 in the first quarter of the prior year, due to foreign exchange
gains in 2002, primarily related to the Japanese yen and the Euro, compared with
foreign exchange losses in the prior year.

         In the first quarter of 2002, the effective tax rate was 30.8% compared
to 21.5% in the first quarter of 2001. This is more fully described in Note 8 to
the Condensed Consolidated Financial Statements.

         A TriZetto equity loss, net, of $202 was recorded in the first quarter
of 2002, compared with a loss of $2,557 in the first quarter of 2001. The
improvement resulted from the absence of goodwill amortization expense in 2002
in accordance with SFAS 142, as well as improved performance by TriZetto.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

RESULTS BY BUSINESS SEGMENT

IMS SEGMENT

         IMS Segment revenue was $289,714 in the first quarter of 2002,
essentially unchanged from $289,576 in the prior year. Excluding the generally
unfavorable impact of a stronger U.S. dollar in the first quarter of 2002,
revenue grew 4.9%. Sales Management revenue of $174,883 in the first quarter of
2002 reflects a decline of 0.8% from the prior year, but grew 4.2% on a
constant-dollar basis driven by new product sales, primarily EarlyView and
Prescriber Validation in the United States, Xponent, Pharmascope, Sales Analyzer
and Strategy Evaluator in Europe, Xplorer.web in Canada and Weekly GP / Pharma
in Japan. Market Research revenue declined 1.7% to $102,795 in the first quarter
of 2002, but grew 3.1% constant dollar, reflecting growth from new clients and
expansion of product capabilities. Other Services generated revenue of $12,036
in the first quarter of 2002, compared with $8,623 in the first quarter of 2001,
reflecting the impact of acquisitions and solid growth in the Company's
consulting business.

         IMS Segment operating income for the first quarter of 2002 was $82,137,
down 6.7% from the comparable period from prior year on a reported basis, but
1.5% higher constant-dollar. The constant-dollar growth resulted from higher
revenues, the benefits of cost-reduction actions initiated in the fourth quarter
of 2001, and the absence of goodwill amortization expense in 2002, partially
offset by higher data-collection and production costs.

CTS SEGMENT

         CTS revenue for the first quarter of 2002, net of inter-segment sales
of $4,834, grew 4.2% to $41,650 from $39,986 in the comparable period of the
prior year due to higher revenues from application management services. CTS
operating income for the three months ended March 31, 2002 increased 9.0% to
$9,146 from $8,389 in the comparable period of the prior year, due to revenue
growth and increased reliance on fixed-bid contracts, which historically have
higher margins.

LIQUIDITY AND CAPITAL RESOURCES

         Net cash provided by operating activities totaled $19,195 for the three
months ended March 31, 2002, compared with $22,413 for the comparable period in
2001. The decrease in cash provided relates primarily to a $10,530 cash receipt
received in the prior year from Nielsen Media Research in respect of the
Donnelley legacy tax contingency, for which there was no comparable receipt in
2002. Adjusting for this receipt, cash provided from operations in 2002 would
have increased by $7,312. This increase results from lower bonus payments and
one-time charge payments made in 2002 versus the prior year, offset by increased
accounts receivable cash requirements due to higher than anticipated days sales
outstanding.

         Net cash used in investing activities amounted to $21,577 for the three
months ended March 31, 2002, compared with $10,277 for the comparable period in
2001. The increase in cash used during 2002 relates primarily to increased
spending on computer software. In addition, the Company was able to fund a
required $3,000 investment in its venture capital portfolio with proceeds from
the sales of securities from within the portfolio.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

         Net cash provided by financing activities amounted to $13,318 for the
three months ended March 31, 2002, compared with a $28,684 for the comparable
period in 2001. The decrease of $15,366 was due primarily to lower proceeds from
the exercise of stock options of $104,684 and higher payments for the purchase
of treasury stock $8,483, offset by a $95,982 increase in net borrowings.

         At March 31, 2002, the Company's Total Current Liabilities exceed
its Total Current Assets by $10,064 primarily as a result of management's
decision to maintain a greater proportion of short-term borrowings versus
longer-term debt instruments. This strategy allows the Company to achieve
lower borrowing costs while providing flexibility to repay debt with cash
flow from operations and proceeds from the exercise of stock options and the
liquidation of equity holdings. Based on estimated future cash flows from
operations, the continued monetization of its venture capital investments,
the ability to monetize other assets including its investment in CTS as well
as the Company's ability to utilize existing lines of credit (see Note 7),
the Company believes it will have sufficient cash and other resources to fund
its short- and long-term business plans, including its current and long-term
obligations, its contingent payments, its stock repurchase program and its
operations.

         On July 19, 2000, the Board of Directors authorized a stock repurchase
program to buy up to 40 million shares, marking the fifth consecutive repurchase
program the Company has implemented. Shares acquired through the repurchase
program are open-market purchases in compliance with Securities and Exchange
Commission Rule 10b-18. During the first quarter of 2002, the Company
repurchased approximately 5.0 million shares of outstanding common stock at a
total cost of $99,707. As of March 31, 2002, approximately 25.6 million shares
have been acquired under this program at a total cost of $616,884.

         IMS believes that its available funds, credit facilities and the
cash flows expected to be generated from operations will be adequate to
satisfy its current and planned operations and needs and contingent payments
for at least the next 12 months. IMS's ability to expand and grow its
business in accordance with current plans, to make acquisitions, repurchase
stock and to meet its long-term capital requirements beyond this 12-month
period will depend on many factors, including the rate, if any, at which its
cash flow increases, its ability and willingness to accomplish acquisitions,
repurchase treasury stock and the availability to IMS of public and private
debt and equity financing, including its current ability to secure bank lines
of credit. IMS cannot be certain that additional financing, if required, will
be available on terms favorable to it, if at all.

         Cash and cash equivalents include amounts at CTS of $91,186 and $84,977
as of March 31, 2002 and December 31, 2001, respectively. The Company owned
58.2% of the CTS common shares outstanding which represented 93.3% of the voting
power at March 31, 2002. To access these cash and cash equivalents, the Company
would have to require CTS to declare and pay a dividend. Furthermore, a portion
of the dividend would be paid to the minority shareholders of CTS.

CHANGES IN CRITICAL ACCOUNTING POLICIES

         Effective January 1, 2002, the Company adopted Statement of
Financial Accounting Standards ("SFAS") No. 142, "Goodwill and Other
Intangible Assets" ("SFAS No. 142"). SFAS No. 142 addresses the initial
recognition and measurement of intangible assets acquired outside of a
business combination and the accounting for goodwill and other intangible
assets subsequent to their acquisition. SFAS No. 142 provides that goodwill
and intangible assets which have indefinite useful lives will not be
amortized but rather will be tested at least annually for impairment at the
reporting unit level. It also provides that intangible assets that have
finite useful lives be amortized. There was no impairment of goodwill upon
adoption of SFAS No. 142 and as such, the Company did not recognize a
transition adjustment during the first quarter of 2002. The effect of
adopting SFAS No. 142 is more fully explained in Note 4. Goodwill may
become impaired as a result of several factors such as increased competition
and lower demand for the Company's products and services.
