The Company has significant investments in non-U.S. countries. Therefore,
changes in the value of foreign currencies affect the Company's Condensed
Consolidated Financial Statements when translated into U.S. dollars. The
currency translation adjustment excludes the impact of the Company's hedging
program. (See Note 7. Financial Instruments with Off-Balance Sheet Risk).

NOTE 1. INTERIM CONSOLIDATED FINANCIAL STATEMENTS

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles 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 Health") in the 1998 Annual Report on Form 10-K. Accordingly, the
accompanying condensed consolidated financial statements do not include all the
information and notes required by generally accepted accounting principles for
complete financial statements. In the opinion of management, all adjustments 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. Certain prior-period amounts have been
reclassified to conform with the 1999 presentation.

NOTE 2. BASIS OF PRESENTATION

This document relates to IMS Health. The Common Stock of IMS Health was
distributed by Cognizant Corporation ("Cognizant", which subsequently changed
its name to Nielsen Media Research Inc., "NMR") to Cognizant's shareholders on
June 30, 1998 (the "Distribution"). The condensed consolidated financial
statements of the Company have been reclassified to reflect Nielsen Media

Class B Common Stock for each share of the Company's Common Stock outstanding on
the July 17 record date, a total of 40,689,648 Gartner Class B shares. (See Note
10. Subsequent Events). Accordingly, the condensed consolidated financial
statements of the Company have been reclassified for all periods presented to
reflect the Gartner equity investment as a discontinued operation (measurement
date July 16, 1999).

IMS Health consists of the market information and decision support services
business for the pharmaceutical and healthcare industries conducted by IMS
Health and various subsidiaries ("IMS") including IMS Health Strategic

Elimination of one month reporting lag in IMS operating entities

Effective in the first quarter of 1999, IMS operating units that previously
reported on a fiscal year ended November 30 revised their reporting period to
conform to the Company's fiscal year ended December 31. The first half results
for 1998 for the IMS operating units include the six months ended May 31. The
$1,040 of net income related to the results of the IMS operating units for the
period December 1 through December 31, 1998 has been recorded directly to
Retained Earnings. In addition, December 1998 included a $3,409 credit which was
recorded as a cumulative translation adjustment. The following table presents
certain selected condensed consolidated IMS operating units financial
information for the one month ended December 31, 1998.

IMS HEALTH INCORPORATED
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS --

(Dollar amounts in thousands, except per share data)

NOTE 4. ACQUISITIONS

During the first quarter of 1999 the Company acquired 100% of the stock of
PharmaFELAX Kft., a pharmaceutical information company based in Hungary. In
connection with the acquisition, the Company recorded goodwill of $3,100.

Walsh Acquisition

On June 24, 1998, Cognizant acquired Walsh International, Inc. ("Walsh"). The
final purchase price of the acquisition was $193,748, including $167,148 of
common stock, $9,521 for stock options issued and $17,079 of direct acquisition
and integration costs.

Walsh shareholders received 6,454,600 shares of Cognizant common stock issued
from treasury stock, with a market value of $167,148. The direct acquisition and
integration costs consist of severance ($4,876), lease terminations ($2,569) and
other direct acquisition and integration costs ($9,634). These acquisition and
integration costs were incurred as a direct result of the plan to exit certain
activities as part of the overall integration effort (such as severance costs
related to Walsh employees) and certain contractual costs (such as Walsh
leases). Incurred acquisition and integration costs to date are within original
projections. Approximately $156,557 has been recorded as the excess of the
purchase price over the fair value of identifiable net assets (goodwill), which
is being amortized on a straight-line basis over 15 years.

PMSI Acquisition

On August 5, 1998, IMS Health acquired certain non-U.S. assets of Pharmaceutical
Marketing Services Inc. ("PMSI"). The final purchase price of the acquisition
was $103,291, consisting of common stock ($75,292), stock options issued
($5,415) and direct acquisition and integration costs ($22,584).

PMSI received 2,395,926 shares of IMS Health common stock issued from treasury
stock, with a market value of $75,292. The direct acquisition and integration
costs consist of severance ($3,794), lease terminations ($1,623), contract
cancellation ($10,935), and other direct acquisition and integration costs
($6,232). The acquisitions and integration costs were incurred as a direct
result of the formal plan to exit certain activities as part of the overall
integration effort (such as severance costs related to PMSI employees) and
certain contractual cancellation costs (such as PMSI contracts and leases).
$115,275 was recorded as the excess of the purchase price over the fair value of
identifiable net assets (goodwill), which is being amortized on a straight-line
basis over 15 years.

Purchase Price Allocation

In connection with both the Walsh and PMSI acquisitions, the Company made
allocations of the purchase price to acquired in-process research and
development ("IPR&D") amounting to $21,900 in the second quarter of 1998 related
to the Walsh acquisition and $10,900 in the third quarter of 1998 related to the
PMSI acquisition. At the date of the respective acquisitions, the development
of the IPR&D projects had not reached technological feasibility and had no
alternative future uses. Accordingly, these costs were expensed as of the
respective acquisition dates.

In accordance with SEC guidance in connection with acquisitions, the amount
allocated to IPR&D reflects the relative value and contribution of the acquired
IPR&D. Consideration was given to the project's stage of completion, the
complexity of the work completed to date, the difficulty of completing the
remaining development, costs already incurred and the projected cost to complete
the projects. In addition, the Company allocated $29,000 at Walsh and $7,700 at
PMSI to existing core technology, representing computer software that is
currently in use. Such amounts are being amortized over 5 years.


The allocation of the Company's aggregate purchase price to the tangible and
identifiable intangible assets acquired and liabilities assumed in connection
with these acquisitions was based primarily on estimates of fair values by an
independent appraisal firm. The allocation is summarized below:

In connection with the PMSI acquisition, the Company evaluated existing IMS
Health product offerings. Based on this strategic assessment, the Company
abandoned certain existing IMS Health software products. The impact of this
decision was to recognize the impairment of certain computer software assets
($36,300), the closure of certain IMS facilities ($800) and the severance of
some IMS employees ($5,600). This resulted in a one-time charge of $43,019
recorded in the third quarter of 1998 as a component of operating income.

NOTE 5. INVESTMENT PARTNERSHIP

Two of the Company's subsidiaries have contributed assets to, and participate
in, a limited partnership. One subsidiary serves as general partner, and all
other partners hold limited partnership interests. The partnership, which is a
separate and distinct legal entity, is in the business of licensing database
assets and computer software. In the second quarter of 1997, third-party
investors contributed $100,000 to the partnership in exchange for limited
partnership interests. The assets, liabilities, results of operations and cash
flows of the partnership are included in the Company's consolidated financial
statements because the Company and its subsidiaries maintain a controlling (85%)
interest in the partnership. The third parties' limited partnership interests
are reflected as a minority interest.

NOTE 6. CONTINGENCIES

The Company and its subsidiaries are involved in 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, cash flows or consolidated financial
position when resolved in a future period. The Company has established reserves
for specific liabilities in connection with these matters to the extent the
Company currently deems them to be probable and estimateable. Management does
not expect the ultimate resolution of the foregoing proceedings, litigations and
tax matters will have a material effect on its financial condition, results of
operations or cash flows.

In addition the Company is subject to certain other contingencies not arising in
the ordinary course of business 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 D&B, A.C. Nielsen Company and IMS (the "IRI Action").

The complaint alleges various violations of the United States antitrust laws,
including alleged violations of Sections 1 and 2 of the Sherman Act. The
complaint also alleges a claim of tortious interference with a contract and a
claim of tortious interference with a prospective business relationship. These
latter claims relate to the acquisition by defendants of Survey Research Group
Limited ("SRG"). IRI alleges that SRG violated an alleged agreement with IRI
when it agreed to be acquired by 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.

On October 15, 1996, defendants moved for an order dismissing all claims in the
complaint. On May 6, 1997 the United States District Court for the Southern
District of New York issued a decision dismissing IRI's claim of attempted
monopolization in the United States, with leave to

Information Resources Litigation - (continued)

replead within sixty days. The Court denied defendants' motion with respect to
the remaining claims in the complaint. On June 3, 1997, defendants filed an
answer denying the material allegations in IRI's complaint, and A.C. Nielsen
Company filed a counterclaim alleging that IRI has made false and misleading
statements about its services and commercial activities. On July 7, 1997, IRI
filed an amended and restated complaint repleading its alleged claim of
attempted monopolization in the United States and realleging its other claims.
On August 18, 1997, defendants moved for an order dismissing the amended claims.
On December 1, 1997, the court denied the motion and, on December 16, 1997,
defendants filed a supplemental answer denying the remaining material
allegations of the amended complaint. Discovery is continuing in this matter.

In light of the potentially significant liabilities which could arise from the
IRI Action and in order to facilitate the distribution by The Dun & Bradstreet
Corporation ("D&B") of shares of Cognizant and ACNielsen Corporation
("ACNielsen"; the parent company of A.C. Nielsen Company) in 1996, D&B,
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 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 D&B 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 which ACNielsen will be able to pay after
giving effect to (i) any plan submitted by such investment bank which 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.

Under the terms of the Distribution Agreement dated October 28, 1996 among D&B,
Cognizant and ACNielsen (the "1996 Distribution Agreement"), as a condition to
the Distribution, IMS Health and Nielsen Media Research are jointly and
severally liable to D&B and ACNielsen for Cognizant's obligations under the 1996
Distribution Agreement.

IMS Health and Nielsen Media Research have agreed that, as between themselves,
IMS Health will assume 75%, and Nielsen Media Research 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 Health agreed to be fully
responsible for any legal fees and expenses incurred during 1998. Nielsen

NOTE 6. CONTINGENCIES - (CONTINUED)

Information Resources Litigation - (continued)

Media Research's aggregate liability to IMS Health for payments in respect of
the IRI Action and certain other contingent liabilities shall not exceed
$125,000.

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.

Other Contingencies

The Company, Cognizant and D&B have entered into global tax planning initiatives
in the normal course of business. These activities are subject to review by the
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, Cognizant or D&B.

Prior to the Distribution, Cognizant and IMS Health entered into certain
agreements that govern the relationship between Nielsen Media Research and IMS
Health and provide for the allocation of tax, employee benefits and certain
other liabilities and obligations arising from periods prior to the
Distribution. Among other things, the agreements set forth principles to be
applied in allocating certain Distribution-related costs and specify portions of
contingent liabilities including those described below to be shared if certain
amounts are exceeded including certain liabilities to D&B that may arise in
connection with the 1996 Distribution Agreement.

The Company has been informed by D&B that the IRS is currently reviewing D&B's
utilization of certain capital losses during 1989 and 1990. While D&B has not
received an assessment with respect to these transactions, it understands that
the IRS will challenge D&B's position. The Company has estimated that D&B's
total cash liability to the IRS, if an assessment were to be made and the IRS
prevail, would be approximately $435,000 for taxes and accrued interest net of
tax benefit as of June 30, 1999. Under the terms of the 1996 Distribution
Agreement, the Company is liable to pay half of such taxes and interest owed to
the IRS to the extent that D&B's total liabilities exceed $137,000. A portion of
the Company's liability would in turn be shared with Nielsen Media Research
under the Distribution Agreement dated as of June 30, 1998 between IMS Health
and Nielsen Media Research. The Company estimates that its share of the
liability, were the IRS to prevail, would be approximately $139,000. This
liability is included in Other Liabilities.

Management does not believe that these matters will have a material adverse
effect on the Company's consolidated financial position or operating results
when they are resolved in future periods. However, should the IRS issue
assessment notices, payment of the Company's share could have a material adverse
effect on cash flows in the periods in which they are made. The Company believes
that it has more than sufficient funds available from operating cash flows and
committed bank lines to cover any such payment without a material effect on its
liquidity or its financial condition.

In connection with the Gartner Spin-Off, the Company and Gartner entered into a
Distribution Agreement and an Agreement and Plan of Merger (the "1999
Distribution Agreements"). Pursuant to the 1999 Distribution Agreements, Gartner
agreed to indemnify the Company and its stockholders for additional taxes that
may become payable as a result of certain actions which may be taken by Gartner
that adversely affect the tax-free treatment of the Gartner Spin-Off. However,
the

(Dollar amounts in thousands, except per share data)


NOTE 6. CONTINGENCIES - (CONTINUED)

Other Contingencies  - (continued)

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 highly unlikely that any such
liabilities will be incurred by the Company.

NOTE 7. FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

The Company transacts business in virtually every part of the world and is
subject to risks associated with foreign exchange rates. The Company's objective
is to reduce earnings and cash flow volatility associated with foreign exchange
rates to allow management to focus its attention on its core business
activities. Accordingly, the Company enters into various contracts which change
in value as foreign exchange rates change to protect the value of a portion of
foreign currency revenues and non-functional currency assets and liabilities. By
policy, the Company maintains hedge coverage between minimum and maximum
percentages of its anticipated foreign exchange exposures over the next year.

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 uses a
variety of financial instruments, primarily forward contracts and purchased
currency options, to hedge committed and anticipated foreign currency
denominated revenues. The principal currencies hedged are the Euro, the Japanese
yen and the Swiss franc. The Company also uses forward contracts to hedge
non-functional currency assets and liabilities. The Company does not enter into
foreign currency transactions for speculative purposes.

Gains and losses on contracts hedging anticipated and committed foreign currency
revenues are deferred until such revenues are recognized and offset changes in
the value of such revenues due to fluctuations in currency exchange rates. Gains
and losses on contracts hedging non-functional currency assets and liabilities
are not deferred and are included in other income/(expense)--net. At June 30,
1999, the notional amount of committed foreign currency revenues hedged was
$74,868. In addition, at June 30, 1999, IMS had approximately $127,661 in
foreign exchange forward contracts hedging non-functional currency assets and
liabilities with various expiration dates through July 1999.

NOTE 8. SUMMARY OF RECENT ACCOUNTING PRONOUNCEMENTS

In March 1998, the American Institute of Certified Public Accountants (the
"AICPA") issued Statement of Position ("SOP 98-1"), "Accounting for the Costs of
Computer Software Developed or Obtained For Internal Use." SOP 98-1 provides
guidance on costs to be capitalized, including when capitalization of such costs
should commence. SOP 98-1 applies to costs incurred after its adoption,
including costs for software projects that are in progress at the time of the
adoption. The implementation of SOP 98-1 effective January 1, 1999 did not have
a material effect on the Company's financial statements.

In April 1998, the AICPA issued SOP 98-5, "Accounting For the Costs of Start-up
Activities." SOP 98-5 requires all costs of start-up activities to be expensed
as incurred. SOP 98-5 is effective for financial statements for the years
beginning after December 15, 1998. The implementation of SOP 98-5 effective
January 1, 1999 did not have a material effect on the Company's financial
statements.

8.   SUMMARY OF RECENT ACCOUNTING PRONOUNCEMENTS - (CONTINUED)

In July 1999, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standard ("SFAS") No. 137, "Accounting for Derivative
Instruments and Hedging Activities - Deferral of the Effective date of SFAS
No.133- an amendment of FASB Statement No. 133". Citing concerns about
companies' ability to modify their information systems in time to apply SFAS
133, the FASB delayed its effective date for one year, to fiscal years beginning
after June 15, 2000 (January 1, 2001 for the Company). In June 1998, the FASB
issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities." SFAS No. 133 requires that all derivative instruments be recorded
on the balance sheet at their fair value. Management continues to evaluate the
effects of this pronouncement on the Company's financial statements.

NOTE 9. OPERATIONS BY BUSINESS SEGMENT

The IMS segment consists of IMS, the leading global provider of market
information and decision-support services to the pharmaceutical and healthcare
industries, and Strategic Technologies, the leading provider of automated sales
support technologies to the pharmaceutical industries. In 1999, the IMS segment
includes the Walsh and PMSI businesses acquired during the second and third
quarters of 1998, respectively, which have been integrated into the IMS
operations. Effective in the first quarter of 1999, the IMS operating units
revised their reporting period to conform to the Company's fiscal year ended
December 31. (See Note 2. Basis of Presentation)

The Emerging Markets segment includes Erisco, a leading supplier of
software-based administrative and analytical solutions to the managed care
industry, and Enterprises, the Company's venture capital unit focused on
investments in emerging businesses. In 1998, it included SSJ, a
marketer of financial application software products to the Japanese market,
which was divested in the first quarter of 1999.

CTS delivers life cycle software development, management and maintenance
technology consulting services through the use of a seamless on-site and
offshore project team. These services include application development and
maintenance services, Year 2000 and Eurocurrency compliance services, testing
and quality assurance services and re-hosting and re-engineering services.

(UNAUDITED)
(Dollar amounts in thousands, except per share data)

NOTE 10. SUBSEQUENT EVENTS

Spin-Off of Equity Investment in Gartner

On November 11, 1998 the Company announced that its Board of Directors had
approved a plan to Spin-Off substantially all of its equity ownership of
Gartner. Pursuant to the 1999 Distribution Agreements 40,689,648 shares of
Gartner Class A Common Stock ("Gartner Class A Shares") were converted into an
equal number of shares of Class B Common Stock of Gartner ("Gartner Class B
Shares"). The Gartner Class B Shares are entitled to elect 80% of Gartner's
Board of Directors, but are otherwise identical to Gartner Class A Shares. On
July 16, 1999, the Company's Board of Directors declared a dividend of all such
Gartner Class B Shares to be distributed on July 26, 1999 to holders of the
Company's Common Stock of record as of July 17, 1999. The distribution consisted
of 0.1302 Gartner Class B Shares for each share of the Company's Common Stock.
The Spin-Off was structured as a tax-free distribution and the Company has
received a favorable ruling from the Internal Revenue Service to that effect. On
July 16, 1999 Gartner declared a special cash dividend payable on July 23, 1999
to holders of record on July 16, 1999. IMS Health's portion of the dividend was
approximately $53.0 million, net of taxes.

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

This discussion and analysis relates to IMS Health and should be read in
conjunction with the accompanying condensed consolidated financial statements
and related notes. IMS Health consists of the market information and decision
support services business for the pharmaceutical and healthcare industries
conducted by IMS Health and various subsidiaries ("IMS") including IMS Health
Strategic Technologies, Inc. ("Strategic Technologies"); ERISCO Managed Care
Technologies, inc. ("Erisco"); Enterprise Associates, LLC ("Enterprises") and a
61.6% interest in Cognizant Technology Solutions Corporation ("CTS").

Spin-Off of Equity Investment in Gartner

On November 11, 1998 the Company announced that its Board of Directors had
approved a plan to Spin-Off substantially all of its equity ownership of
Gartner. Pursuant to the 1999 Distribution Agreements 40,689,648 Gartner Class A
Shares were converted into an equal number of Gartner Class B Shares. On July
16, 1999, the Company's Board of Directors declared a dividend of all such
Gartner Class B Shares to be distributed on July 26, 1999 to holders of the
Company's Common Stock of record as of July 17, 1999. The distribution consisted
of 0.1302 Gartner Class B Shares for each share of the Company's Common Stock.
The Spin-Off was structured as a tax-free distribution and the Company has
received a favorable ruling from the Internal Revenue Service to that effect. On
July 16, 1999 Gartner declared a special cash dividend payable on July 23, 1999
to holders of record on July 16, 1999. IMS Health's portion of the dividend was
approximately $53.0 million, net of taxes. These cash proceeds will be used in
the third quarter to pay down short term borrowings incurred to fund the
Company's accelerated stock repurchases during the second quarter.

At June 30, 1999, the Company owned approximately 47.6 million Gartner shares.
Approximately 40.6 million shares were distributed to IMS Health shareholders as
described above. The Company intends to monetize its remaining position in
Gartner, consisting of approximately 6.9 million Gartner Class A Shares and
warrants to purchase a further 599,400 Gartner Class A Shares, subject to the
terms of the 1999 Distribution Agreements. The Company's Gartner Class A shares
will be accounted for as an "available for sale" security under SFAS No. 115
"Accounting for Certain Investments in Debt and Equity Securities". Recognition
of the unrealized gain at the spin date will be recorded as Other Comprehensive
Income and included as a component of equity. Subsequent changes in fair value
from the measurement date of the spin will also be recorded as Other
Comprehensive Income and included as a component of equity. Upon sale of these
securities, the unrealized gain related to those securities at the spin date
will be recognized in Discontinued Operations and any subsequent changes in fair
value will be recognized in Continuing Operations. In connection with the
Gartner Spin-Off, options granted under the Company's plans were adjusted to
recognize the effect of the value of the distribution, thereby slightly
increasing the number of IMS Health shares issuable on exercise.

Walsh Acquisition

On June 24, 1998, Cognizant acquired Walsh International, Inc. ("Walsh").

        OF OPERATIONS (CONTINUED) (DOLLAR AMOUNTS IN THOUSANDS, EXCEPT PER SHARE

Purchase Price Allocation

In connection with both the Walsh and PMSI acquisitions, the Company made
allocations of the purchase price to acquired in-process research and
development ("IPR&D"). Management continues to support the IPR&D efforts that
were underway at the time of the Walsh and PMSI acquisitions. IMS Health is on
target to begin realizing the benefits from these various projects through
product introductions at various launch dates through January 2000. There are
currently no material variations from the underlying projections and assumptions
made at the time of the purchase price allocations.

Elimination of one month reporting lag in IMS operating segment

Effective in the first quarter of 1999, the IMS operating units that previously
reported on a fiscal year ending November 30 revised their reporting period to
conform to the Company's fiscal year ending December 31.
(the "Calendarization"). (See Note 2.  Basis of Presentation).

Operations

Revenue for the second quarter increased by 23.0% to $332,652 from $270,496 for
the second quarter of the prior year. Revenue for the first six months increased
26.3% to $645,894 from $511,464 for the comparable period a year ago. Adjusting
the quarter and the first half of 1998 for the Calendarization and the sale of
Super Systems Japan ("SSJ"), revenue increased by 24.7% and 25.1%, respectively.
This increase reflected double-digit constant dollar revenue growth at IMS,
Erisco and CTS as well as the first full year impact of the Walsh and PMSI
acquisitions.

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

Operating Results - (continued)

The impact of a stronger U.S. dollar decreased reported revenue by less than 1%
for the quarter and first half, including the impact of the Company's hedging
program.

Operating income for the second quarter was $62,755, compared to operating
losses of $13,912 for the second quarter of the prior year. Operating results in
the second quarter of 1999 and 1998 include Year 2000 costs ("Y2K costs") of
$7,923 and $12,330, respectively. Adjusting for Y2K costs; 1999 charges related
to the Gartner Spin-Off ($7,500), the Calendarization, 1998 charges related to
the Distribution ($30,125), the 1998 in-process research and development
write-off ($21,900) and one-time charge ($5,000) related to the Walsh
acquisition, operating income for the second quarter of 1999 increased by 33.5%.

First-half operating income was $117,465 compared with $4,816 for the comparable
period a year ago. First-half operating results in both years include Y2K costs
of $15,800 and $22,301, respectively. Adjusting for Y2K costs, 1999 charges
related to the Gartner Spin-Off ($7,500); the Calendarization, 1998 charges
related to the Distribution ($35,025), the 1998 research and development
write-off ($21,900) and one-time charge ($5,000) related to the Walsh
acquisition, operating income for the first-half of 1999 increased by 35.4%.

Adjusted operating income growth in the second quarter and first half of 1999
outpaced revenue growth primarily due to the Company's ability to leverage its
worldwide resources. The impact of a stronger U.S. dollar impacted adjusted
operating income growth by less than 1% in the second quarter and the first
half, including the impact of the Company's hedging program.

Non-operating income-net for the second quarter was $3,676 compared with $14,859
for the second quarter of the prior year. The decrease is due primarily to a
1998 gains related to the CTS IPO ($12,777).

Non-operating income-net for the first half was $9,287 compared with $26,402.
The decrease is due primarily to 1998 gains related to the CTS IPO ($12,777).

The second quarter 1999 effective tax rate of 30.5% was impacted by a
non-deductible one-time charge of $7,500 related to the Gartner Spin-Off. The
second quarter 1998 effective tax rate was impacted by a portion of the one-time
charge related to the Distribution ($30,125) and the research and development
write-off ($21,900) and one-time charge ($5,000) related to the Walsh
acquisition. Those items did not give rise to a tax benefit. Excluding those
items, the Company's effective tax rate from operations was 27.4% for the second
quarter of 1999 and 1998. The Company's lower effective tax rate is attributable
to numerous global tax planning initiatives. For example, to consolidate certain
of its international operations, in 1999 and 1998 the Company engaged in certain
non-U.S. reorganizations which give rise to tax deductible non-U.S. intangible
assets.

The Company's effective tax rate was 29.0% for the first half of 1999, compared
with an effective tax rate of 68.0% in the comparable period of the prior year.
The first half of 1999 effective tax rate was impacted by a non-deductible
one-time Gartner spin-related charge ($7,500). Excluding the charge related to
the Gartner Spin-Off, the 1998 charges related to the Distribution, the 1998
research and development write-off and one-time charge related to the Walsh
acquisition as noted above, the effective tax rate from operations for the first
half of 1999 and 1998 was 27.4%.

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

Results by Business Segment

IMS Segment

The IMS segment consists of IMS, the leading global provider of market
information and decision-support services to the pharmaceutical and healthcare
industries, and Strategic Technologies, the leading provider of automated sales
support technologies to the pharmaceutical industries.

Effective in the first quarter of 1999, IMS operating units that previously
reported on a fiscal year ended November 30 revised their reporting period to
conform to the Company's fiscal year ended December 31. (See Note 2. Basis of
Presentation)

IMS Segment revenue for the second quarter of 1999 increased 21.5% to $303,132
from $249,422 in the second quarter of the prior year. Adjusting 1998 revenue
for the Calendarization and the impact of a stronger U.S. dollar, revenue for
the second quarter 1999 increased by 22.7%. Market Research Products increased
7.0% to $99,347, Sales Management Products increased 29.2% to $166,755 and Other
Services increased 38.4% to $37,030. This growth was due primarily to geographic
expansion of Sales Management Products and Services and the first full year
effect of the Walsh and PMSI acquisitions.

Second quarter operating income increased 159.6% to $73,173 from $28,186 in the
prior year. Excluding Y2K costs and the Calendarization, operating income for
1999 increased 25.5%. Adjusted operating income growth outpaced revenue growth
due primarily to the segment's ability to leverage its worldwide resources.

IMS Segment revenue for the first half of 1999 increased 24.5% to $588,633 from
$472,823 in the prior year. Adjusting 1998 revenue for the Calendarization and
the impact of a stronger U.S. dollar, revenue for the second half 1999 increased
by 22.4%. Market Research Products increased 7.5% to $193,137, Sales Management
Products increased 30.1% to $325,565 and Other Services increased 31.6% to
$69,931. This growth was due primarily to geographic expansion of Sales
Management Products and Services and the first full year effect of the Walsh and
PMSI acquisitions.

IMS Segment operating income for the first half of 1999 increased 121.1% to
$130,721 from $59,112 in the first half of the prior year. Excluding Y2K costs
and the impact of the Calendarization, operating income for the first half of
1999 increased 25.6%.

Emerging Markets Segment

The Emerging Markets segment includes Erisco, a leading supplier of
software-based administrative and analytical solutions to the managed care
industry, and Enterprises, the Company's venture capital unit focused on
investments in emerging businesses. In 1998, this segment included SSJ which was
divested in the first quarter of 1999.

Emerging Markets revenue for the second quarter of 1999 decreased 7.6% to
$11,620 from $12,580 in the prior year. This decrease was due primarily to the
absence of revenues from SSJ during 1999. Excluding SSJ, Emerging Markets
revenue for the second quarter of 1999 increased by 20.1%. Operating income
increased to $1,325 in the second quarter from $103 in the second quarter of the
prior year. Excluding SSJ, operating income for the second quarter of 1999
increased 29.8%.

Emerging Markets Segment - (continued)

Emerging Markets revenue for the first half of 1999 decreased 6.8% to $22,226
from $23,843 in the prior year. This decrease was due primarily to the absence
of revenues from SSJ during 1999. Excluding SSJ, Emerging Markets revenue
increased by 19.8% in the first half. Emerging markets operating income for the
first half of 1999 increased to $2,220 from a loss of $101 in the first half of
the prior year.

CTS Segment

CTS delivers life cycle software development, management and maintenance
technology consulting services to its customers through the use of a seamless
on-site and offshore project team. These services include application
development and maintenance services, Year 2000 and Eurocurrency compliance
services, testing and quality assurance services and re-hosting and
re-engineering services.

CTS revenue, net of intersegment sales, increased to $17,900 in the second
quarter of 1999 from $8,494 in the prior year. The increase is due to continuing
strong demand for application development, management and maintenance services
and the addition of new customers. Operating income increased to $3,870 from
$1,582 in the second quarter of the prior year.

CTS revenue for the first half of 1999, net of intersegment sales, increased
136.8% to $35,035 from $14,798 in the prior year. CTS operating income for the
first half of 1999 increased 195.4% to $7,940 from $2,688 in the first half of
the prior year.

Condensed Consolidated Statement of Cash Flows

Net Cash provided by operating activities totaled $111,397 for the six months
ended June 30, 1999 compared with $78,359 in 1998. The $33,038 increase is due
primarily to increased income from continuing operations ($79,973) which was
partially offset by the absence of the 1998 IPR&D write-off ($21,900) and higher
other working capital ($6,983). During the month of December 1998, IMS generated
$30,664 of cash, including a significant decrease in accounts receivable
($35,353). As a consequence of the Calendarization, the December 1998 cash flows
from IMS operating units are not included in the Company's first six months net
cash provided by operating activities.

Net Cash used in investing activities totaled $45,355 for the first six months
of 1999 compared with $19,316 used during the comparable period in 1998. The
$26,039 increase in cash used in investing activities is due primarily to
acquisition and integration payments ($21,768).

Net Cash (used in) / provided by financing activities was ($140,565) cash used
for the six months ended June 30, 1999 compared with $355,146 cash provided in
1998. The decrease in cash provided by financing activities of $495,711 was
primarily due to the 1998 proceeds from debt assumed by Nielsen Media Research
($300,000), proceeds from the 1998 CTS IPO ($27,128), increased payments for the
purchase of treasury stock ($214,842) and lower proceeds from the exercise of
stock options ($23,052) which were partially offset by increased proceeds from
short-term debt ($70,909, net of repayments). Short-term borrowings are used
from time to time to temporarily fund the Company's ongoing stock repurchase
program.

Condensed Consolidated Statement of Cash Flows - (continued)

Cash Flow from Discontinued Operations was zero for the first six months of 1999
compared to a use of ($17,173) in the same period of 1998. There was no Cash
Flow from the Gartner Discontinued Operations in 1999 or 1998. Nielsen Media
Research accounted for all of the Discontinued Operations Cash Flow in 1998.
Subsequent to June 30, Gartner declared a Cash Dividend from which the Company
will receive approximately $53 million of after tax Cash Flow from Discontinued
Operations in the third quarter.

The Company's exisiting balances of cash, cash equivalents and marketable
securities, and cash generated from operations and debt capacity are expected to
be more than sufficient to meet the Company's current long-term and short-term
requirements including cash dividends, acquisitions, stock repurchase programs
and other contingencies.

Changes in Financial Position at June 30, 1999 Compared to December 31, 1998

Cash & Cash Equivalents decreased to $150,310 at June 30, 1999 from $206,390 at
December 31, 1998, due primarily to the purchase of treasury stock
($222,651) which was partially offset by cash from operating activities
($111,397) and cash provided by IMS operating units during December 1998
($30,664). (See Note 2. The Basis of Presentation).

Accounts Receivable decreased to $263,518 at June 30, 1999, from $324,219 at
December 31, 1998 due primarily to increased collections. As a result, days
sales outstanding improved to 71 days for the quarter compared to 100 days' for
the year ended December 31, 1998.

Securities and Other Investments decreased to $94,092 at June 30, 1999 from
$106,276 at December 31, 1998 due primarily to the sale of certain Enterprises
investments, partially offset by additional investments.

Net-Assets of Discontinued Operations increased to $265,019 at June 30, 1999,
from $240,708 at December 31, 1998, reflecting after-tax income from
discontinued operations ($24,311).

Short Term Debt increased to $109,729 at June 30, 1999, from $39,169 at December
31, 1998 due primarily to increased borrowings used from time to time to
temporarily fund the Company's ongoing stock repurchase program. The proceeds
from the Gartner dividend will be used in the third quarter to pay down short
term borrowings incurred to fund the Company's accelerated stock repurchases
during the second quarter.

Accrued Liabilities decreased to $235,180 at June 30, 1999, from $298,625 at
December 31, 1998 due primarily to payments related to the PMSI and Walsh direct
acquisition and integration costs and accruals for salaries, wages, bonuses and
other compensation.

Shareholders' Equity decreased to $693,196 at June 30, 1999 from $825,270 at
December 31, 1998, due primarily to the purchase of treasury stock ($222,651),
change in cumulative translation adjustment ($28,031), change in unrealized
gains on investments ($9,307) and dividends paid ($12,660), partially offset by
net income ($114,278) and proceeds from stock option exercises ($20,180). Also
effecting shareholder's equity is the $1,040 of net income related to the
results of the IMS operating units for the period December 1 through December
31, 1998 and a $3,409 cumulative translation adjustment for the same period.
(See Note 2. Basis of Presentation).

Year 2000

Many existing computer systems and software applications use two digits, rather
than four, to record years (for example "98" instead of "1998"). Unless
modified, such systems will not properly record or interpret years after 1999,
which could lead to business disruptions. This is known as the "Year 2000 issue"
("Year 2000").

The Company began to address the Year 2000 issue in 1996. In 1997, the Company
created a Year 2000 Task Force (the "Task Force") to manage overall risks and to
facilitate activities across

the entire Company. CTS, a majority owned subsidiary, is being used to convert
the majority of the systems to allow most internal staff members to focus on the
core business. The Company has also used outside services to assist in
conversion and to assess the progress of its Year 2000 program.

The Task Force developed a conversion methodology that included three phases:
analysis, coding and testing, and testing and implementation. The analysis phase
includes planning, inventory and impact analysis. The coding and testing phase
involves code changes, using conversion rules and criteria and unit testing,
verifying and documenting the results of the conversion. The testing and
implementation phase includes system test across platforms and verification of
data, an acceptance test within the user environment, and implementation or
releasing the systems back into production. This conversion methodology has been
utilized throughout the Company to achieve systems compliance by the Year 2000.

The creation of customer products relies on the receipt of data from external
data suppliers and the Company's ability to convert the data and deliver the
information to its customers. The consolidation of the data is principally
performed at central processing locations. The Company believes central systems
represent approximately 85% of its Year 2000 efforts. The Company operates
central processing facilities in Germany, England, the United States and Japan.
The systems at these sites contained the most lines of code required to undergo
conversion. At June 30, 1999, the Company has completed 99% of Year 2000
conversions at central processing locations.

IMS Health continues to enhance its existing product portfolio and continues to
launch new products. There is an ongoing effort to ensure this software is Year
2000 compliant. In addition, the Company has decided to replace certain
non-compliant software. These new product and replacement projects are on track
to be completed and deployed by the fourth quarter and continue to be under
close scrutiny by the Task Force.

The Company operates local offices in over 90 countries with about half of them
using systems for data collection, panel administration and customized local
requirements. Varied approaches are utilized to ensure Year 2000 compliance. In
some cases, specialized teams from CTS are being used to assist the local
offices with all phases of their system conversions and hardware compliance.

At June 30, 1999, the Company has completed 98% of Year 2000 conversions of
local systems and personal computer applications in the United States and
Europe. The rest of the world is at approximately 96% completion. Year 2000
compliance is expected to be achieved by the end of the third quarter.

The Company's Year 2000 project incorporates administrative operations systems
and software such as accounts receivable, payroll, accounts payable and the
general ledger systems and are 99% compliant.

The Company developed an internal audit program that examines the testing and
effectiveness of controls, assesses the accuracy and completeness of inventories
and reviews the documentation for completeness and accuracy. As of the beginning
of the second quarter, audits and follow-up

Year 2000 - (continued)

audits have occurred in the United States, England, Japan and Germany. The
company performs audits on the local country conversions with the assistance of
CTS and outside consultants. To date approximately 90% of IMS Health revenue has
been audited for Year 2000 compliance. These audits will continue throughout the
world until Year 2000 with several sites revisited to ensure continued
compliance.

The Company engaged TRW to conduct an audit review of the Year 2000 program for
business critical and mission critical systems in sixteen locations. These
audits were conducted in the first half of 1999 and focused on survivability,
preparedness and due diligence in addressing the Year 2000 problem. Any issues
identified as a result of these audits will be addressed in the third quarter.

The Company relies on over 16,000 suppliers of electronic data and has been
proactive in working with these suppliers to determine their Year 2000 readiness
and ability to maintain data flow continuity. A program consisting of seminars,
visits, mailings and telephone calls continues to be administered to track the
status of and assess and address risks associated with Year 2000 readiness by
the Company's key data suppliers.

In some instances, IMS Health receives data from governments and hospitals.
Continued receipt of their data will be a function of their Year 2000
compliance. Based on information from the Company's data sources, Year
2000 compliance information has been incomplete or progress to date has been
unsatisfactory in some areas. The Company assesses risk regarding the readiness
of data sources through testing and the use of a detailed questionnaire
regarding Year 2000 conversion plans in order to verify the supplier's ability
to continue to deliver data. As a contingency, statistically valid methods of
data extrapolation are being developed in the event the supply of data from a
limited number of suppliers is incomplete or found to be unusable. Investigation
of alternate sources are pursued when the risk assessment determines the data
source to have a high risk of impacting the Company's ability to deliver
products and services.

Throughout 1999 the Company's Year 2000 efforts will focus on (i) the testing
the critical components of the Company's systems; (ii) the continued assessment
of supplier readiness to address the Year 2000 conversion; and (iii) finalizing
contingency plans to address unanticipated issues.

External and internal costs of addressing the Year 2000 issue are expensed as
incurred. It is currently estimated that the aggregate cost of the Company's
Year 2000 program will be approximately $75,000 to $80,000. Through June 30,
1999 the Company has incurred $70,541 of which $44,922 was incurred in 1998. The
Company expects to incur between $4,000 and $9,000 during the remainder of 1999.
These estimates do not include the costs of software and systems that are being
replaced or upgraded in the normal course of business.

The cost of addressing the Year 2000 issue and the dates which the Company
currently expects to complete Year 2000 compliance are based on the current best
estimates of management, which are derived utilizing various assumptions
regarding the future events. There can be no guarantee that these estimates will
be achieved, and actual results may differ materially. Specific factors that may
cause such material differences include, but are not limited to, the
availability and cost of personnel trained in this area of expertise, the
ability to locate and correct all relevant computer codes, and the success of
customers and suppliers in addressing the Year 2000 issue. The

The Year 2000 - (continued)

Company's plans are dependent on industries out of the Company's direct control
such as utilities and transportation.

The above expectations are subject to uncertainties. For example, if the Company
is unsuccessful in identifying or fixing all Year 2000 problems in its critical
operations, or effected by the inability of its data suppliers or major
customers to continue operations due to such a problem, the Company's results of
operations or financial condition could be materially impacted.

The Year 2000 statements set forth above are designated as "Year 2000 Readiness
Disclosures" pursuant to the Year 2000 Information Readiness Disclosure Act
(P.L. 105-271).

Euro Conversion

On January 1, 1999, 11 member countries of the European Union established fixed
exchange rates between their existing currencies and the European Union's common
currency ("Euro"). The transition period for the introduction of the Euro is
between January 1, 1999 and January 1, 2002.

The Company instituted plans for the introduction of the Euro and has addressed
the related issues, including the conversion of information technology systems,
recalculating currency risk, recalibrating derivatives and other financial
instruments, continuity of contracts, taxation and accounting records, and the
increased price transparency resulting from the use of a single currency in
eleven participating countries which may affect the ability of some companies to
price products differently in the various European markets. The Company believes
that differences in national market size, data collection requirements and
specific product specifications required due to the diverse market information
needs in the healthcare markets of Europe will reduce the potential for price
harmonization in most of the Company's product ranges.

IMS Health's expectations regarding the Euro currency issue are forward-looking
statements that involve a number of risks and uncertainties that could cause
actual results to differ materially from the projected results. Factors that may
cause these differences include, but are not limited to, the ability or
willingness of third parties to convert systems in a timely manner and the
actions of governmental agencies or other third parties with respect to Euro
currency issues.

2.2(c) of this Agreement, on the Declaration Date the Board of Directors of
Gartner shall declare a pro rata cash dividend to all holders of record of
Gartner Common Stock as of the Cash Dividend Record Date in the aggregate amount
of $125 million (the "Cash Dividend").

of this Agreement, Gartner shall, as soon as practicable following completion of
the Recapitalization and the Distribution, in compliance with the rules and
regulations of the Commission, including Regulation 13E under the Exchange Act,
commence a "Dutch auction" tender offer (the "Self Tender Offer") for a number
of shares of Class A Common Stock and Class B Common Stock in the aggregate
equal to at least 15% of the total number of shares of Gartner Common Stock
outstanding immediately following the Distribution (the "Minimum Self Tender
Amount"), with such purchases allocated between shares of Class A Common Stock
and Class B Common Stock on a pro rata basis based on the relative numbers of
shares of such classes outstanding


<PAGE>


                                                                             15


immediately following the Distribution ("Pro Rata"). Subject to the previous
sentence, Gartner shall acquire all shares properly tendered in response to such
Self Tender Offer as promptly as practicable following commencement thereof,
subject to reasonable and customary conditions and other terms and reasonable
range of purchase prices based on recent trading prices of Gartner Class A and
Class B Common Stock, which conditions, terms and ranges shall be determined by
the Board of Directors of Gartner in good faith. Subject to the conditions set
forth in Section 2.2(c) of this Agreement, Gartner shall, as soon as practicable
following completion of the Self Tender Offer, in compliance with the rules and
regulations of the Commission, including Rule 10b-18 under the Exchange Act,
purchase through an open-market stock purchase program an amount of shares of
Common Stock equal to (i) 4.99% of the number of shares of Gartner Common Stock
plus or minus (ii) the amount, if any, by which the Minimum Self Tender Amount
is less than or exceeds, respectively, the number of shares of Gartner Common
Stock actually purchased in the Self Tender Offer (the "Minimum Open Market
Amount"), with such purchases allocated Pro Rata between shares of Class A
Common Stock and Class B Common Stock (the "Open Market Repurchase Program" and,
together with the Self Tender Offer, the "Stock Repurchase"). Gartner shall
commence the Open Market Repurchase Program as promptly as practicable (subject
to market conditions) after the Self Tender Offer and shall in any event
complete the Open Market Repurchase Program in an orderly manner within two
years after the Distribution Date. Gartner agrees that it will not repurchase
any shares of Class A Common Stock or Class B Common Stock in the Self Tender
Offer beneficially owned by any of its directors or officers and will not
knowingly repurchase any shares of Class A Common Stock or Class B Common Stock
in the Stock Repurchase beneficially owned by any of its directors or officers
(it being understood that in the case of the Open Market Repurchase Program
effected through brokers, Gartner shall be deemed not to have knowledge of the
identity of any seller).

     (c) Conditions of the Cash Dividend and Stock Repurchase. The obligation of
the Board of Directors of Gartner to declare the Cash Dividend on the

     it prior to the Declaration Date;

          (ii) All conditions to the Recapitalization shall have been satisfied

The foregoing conditions are for the sole benefit of Gartner and shall not give
rise to or create any duty on the part of Gartner to waive or not waive any such
condition.

foregoing, IMS HEALTH and Gartner shall use their commercially reasonable

     of the Stock Repurchase and the approval of the Recapitalization by the
     stockholders of Gartner. Each of this Agreement and the Recapitalization
     Agreement constitutes, and each other agreement or instrument executed and
     delivered or to be executed and delivered by Gartner pursuant to this
     Agreement or the Recapitalization Agreement will, upon such execution and
     delivery, constitute, a legal, valid and binding obligation of Gartner,
     enforceable against Gartner in accordance with its terms, subject to the
     effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
     moratorium and other similar laws relating to or affecting creditors'
     rights generally, general equitable principles (whether considered in a
     proceeding in equity or at law) and an implied covenant of good faith and
     fair dealing.

          (iii) Consents and Filings. Except (w) for the NYSE Listing

     Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
     Act") and (z) for the filing of the Proxy Statement and the Form 8-A and
     any other reports or documents required to be filed under the Exchange Act,
     no consent of, or filing with, any Governmental Entity which has not been
     obtained or made is required for or in connection with the execution and
     delivery of this Agreement or the Recapitalization Agreement by Gartner,
     and the consummation by Gartner of the transactions contemplated hereby or
     thereby.

          (iv) Noncontravention. The execution, delivery and performance of this
     Agreement and the Recapitalization Agreement by Gartner does not, and the

     rule or regulation, (y) violate any provision of the Certificate of
     Incorporation or By-Laws of Gartner, or (z) violate any provision of, or
     result in the termination or acceleration of, or entitle any party to
     accelerate any obligation or indebtedness under, any mortgage, lease,
     franchise, license, permit, agreement, instrument, law, order, arbitration
     award, judgment or decree to which Gartner or any of its Subsidiaries is a
     party or by which any of them are bound.

          (v) Litigation. There are no actions or suits against Gartner pending,
     or to the knowledge of Gartner, threatened which seek to, and Gartner is
     not subject to any judgments, decrees or orders which, enjoin or rescind
     the transactions contemplated by this Agreement or the Recapitalization
     Agreement or otherwise prevent Gartner from complying with the terms and
     provisions of this Agreement or the Recapitalization Agreement.

          (vi) Change of Control Adjustments. None of the Recapitalization, Cash
     Dividend, Stock Repurchase or Distribution or any of the other transactions

                                                                             20


     contemplated hereby or by the Recapitalization Agreement will constitute a
     "change of control" or otherwise result in the increase or acceleration of
     any benefits, including to employees of Gartner, under any agreement to
     which Gartner or any of its Subsidiaries is a party or by which it or any
     of its Subsidiaries is bound.

          (vii) Surplus and Solvency. Gartner has on the date hereof, and at the
     Declaration Date and the Cash Dividend Date will have, surplus (as defined
     in and computed in accordance with Sections 154 and 244 of the DGCL) in
     excess of the amounts of cash required to effect the Cash Dividend and
     Stock Repurchase. Gartner is on the date hereof, and immediately after the
     payment of the Cash Dividend will be, and at all times during the period it
     is effecting the Stock Repurchase will be, Solvent. For purposes of this
     Section 2.7(a)(vii), "Solvent" means, at any date of determination, (x) the
     fair saleable value of Gartner's consolidated assets will exceed Gartner's
     consolidated liabilities as of such date, (y) Gartner will not have as of
     such date an unreasonably small amount of capital with which to conduct its
     business and (z) Gartner will be able to pay its debts as they mature.

          (viii) Certain Transactions. Except for transactions or other actions
     that occurred prior to July 1, 1997 or that are described in Schedule
     2.6(a), neither Gartner nor any other member of the Gartner Group has
     engaged in any transaction or taken any other action through the date
     hereof involving or relating to the stock of Gartner or options, warrants
     or other rights to acquire stock of Gartner. None of the transactions and
     other actions described in Schedule 2.6(a) which occurred prior to October
     1, 1998 (the "Proposal Date") were undertaken by Gartner in contemplation
     of the Distribution or are related to the Distribution (the parties agree
     that the concept of the Distribution was solely conceived by IMS HEALTH and
     first communicated to Gartner on the Proposal Date), and all transactions
     and actions by Gartner described in Schedule 2.6(a) which occurred between
     the Proposal Date and the date hereof were undertaken in the ordinary
     course of business, and if other than compensatory stock plan issuances,
     were pursuant to a letter of intent which was executed by Gartner prior to
     the Proposal Date.

     (b) IMS HEALTH hereby represents and warrants to Gartner as follows:

          (i) Organization; Good Standing. IMS HEALTH is a corporation duly
     incorporated, validly existing and in good standing under the laws of the
     State of Delaware and has all corporate power required to consummate the
     transactions contemplated hereby and by the Recapitalization Agreement.

          (ii) Authorization. The execution, delivery and performance by IMS
     HEALTH of this Agreement and the Recapitalization Agreement and the
     consummation by IMS HEALTH of the transactions contemplated hereby and
     thereby have been duly authorized by all necessary corporate action on the
     part of IMS HEALTH, other than the formal declaration of the Distribution.
     Each of this Agreement and the Recapitalization Agreement constitutes, and
     each other agreement or instrument executed and delivered or

<PAGE>


                                                                            21


     to be executed and delivered by IMS HEALTH pursuant to this Agreement will,
     upon such execution and delivery, constitute, a legal, valid and binding
     obligation of IMS HEALTH, enforceable against IMS HEALTH in accordance with
     its terms, subject to the effects of bankruptcy, insolvency, fraudulent
     conveyance, reorganization, moratorium and other similar laws relating to
     or affecting creditors' rights generally, general equitable principles
     (whether considered in a proceeding in equity or at law) and an implied
     covenant of good faith and fair dealing.

          (iii) Consents and Filings. Except (x) for the IRS Ruling, and (y) as
     required under the HSR Act and any other reports or documents required to
     be filed under the Exchange Act, no material consent of, or filing with,
     any Governmental Entity which has not been obtained or made is required to
     be obtained or made by IMS HEALTH for or in connection with the execution
     and delivery of this Agreement or the Recapitalization Agreement by IMS
     HEALTH, and the consummation by IMS HEALTH of the transactions contemplated
     hereby or thereby.

          (iv) Noncontravention. The execution, delivery and performance of this
     Agreement and the Recapitalization Agreement by IMS HEALTH does not, and
     the consummation by IMS HEALTH of the transactions contemplated hereby and
     thereby will not, (x) violate any applicable federal, state or local
     statute, law, rule or regulation, (y) violate any provision of the
     Certificate of Incorporation or By-Laws of IMS HEALTH or (z) violate any
     provision of, or result in the termination or acceleration of, or entitle
     any party to accelerate any obligation or indebtedness under, any mortgage,
     lease, franchise, license, permit, agreement, instrument, law, order,
     arbitration award, judgment or decree to which IMS HEALTH or any of its
     Subsidiaries is a party or by which any of them are bound.

          (v) Litigation. There are no actions or suits against IMS HEALTH
     pending, or to the knowledge of IMS HEALTH, threatened which seek to, and
     IMS HEALTH is not subject to any judgments, decrees or orders which, enjoin
     or rescind the transactions contemplated by this Agreement or the
     Recapitalization Agreement or otherwise prevent IMS HEALTH from complying
     with the terms and provisions of this Agreement or the Recapitalization
     Agreement.

     Section 2.7. Certain Post-Distribution Transactions. (a)(i) Gartner and IMS
HEALTH shall each comply and shall cause its Subsidiaries to comply with and
otherwise not take action inconsistent with each representation made by such
respective party to the IRS in connection with the requests by IMS HEALTH for
the IRS Ruling and the IRS Supplemental Ruling, if any, and (ii) until two years
after the Distribution Date, Gartner will maintain its status as a company
engaged in the active conduct of a trade or business, as defined in Section
355(b) of the Code.

     (b) If Gartner (or any of its Subsidiaries) fails to comply with any of its
obligations under Section 2.7(a) above or takes any action or fails to take any
required action, and such failure to comply, action or omission contributes to a
determination that the

<PAGE>


                                                                             22



Distribution fails to qualify under Section 355(a) of the Code or that the
Gartner shares fail to qualify as qualified property for purposes of Section
355(c)(2) of the Code by reason of Section 355(e) of the Code, then Gartner
shall indemnify and hold harmless IMS HEALTH and each member of the consolidated
group of which IMS HEALTH is a member and the shareholders of IMS HEALTH from
and against any and all federal, state and local taxes, including any interest,
penalties or additions to tax, imposed upon or incurred by IMS HEALTH, any
member of its group or any stockholder of IMS HEALTH as a result of the failure
of the Distribution to qualify under Section 355(a) of the Code or the
application of Section 355(e) (any such tax, interest, penalty or addition to
tax, an "IMS HEALTH Tax Liability"); provided however that, notwithstanding any
other provision of this Agreement, Gartner shall not be required to indemnify
and hold harmless, and shall have no liability to, IMS HEALTH or any member of
the consolidated group of which IMS HEALTH is a member or any stockholder of IMS
Health for any such IMS HEALTH Tax Liability imposed or incurred (or that would
have been imposed or incurred) solely as a result of

          (i) the Recapitalization and the Distribution,

          (ii) sales or other dispositions of Gartner Common Stock or warrants
     to purchase Gartner Common Stock by IMS HEALTH or any affiliate or IMS
     HEALTH after the Distribution Date,

          (iii) repurchases by Gartner pursuant to and in compliance with
     Section 2.2(b) of this Agreement or the repurchases that are set forth in
     the IRS Ruling, or the request for the IRS Supplemental Ruling or, if
     granted at such time, the IRS Supplemental Ruling or any other IRS ruling
     that may be obtained by IMS HEALTH substantially similar to the requested
     IRS Supplemental Ruling,

          (iv) issuances by Gartner after the date hereof through the second
     anniversary of the Distribution Date of stock options and other stock
     awards under compensatory stock programs, in the ordinary course of
     business and consistent with past practice, to acquire an amount of Class A
     Common Stock equal to or less than 4% of the outstanding Gartner Common
     Stock on the date hereof,

          (v) issuances by Gartner after the second anniversary of the
     Distribution Date of stock options and other stock awards under
     compensatory stock programs, unless, in the case of any such issuance, such
     issuance was pursuant to a plan, undertaking or understanding adopted or
     entered into during such two-year period and not exempt under clause (iv)
     hereof,

          (vi) issuances by Gartner of Class A Common Stock after the date
     hereof pursuant to the exercise of outstanding stock options and other
     rights under compensatory stock programs existing at the date hereof,

          (vii) issuances by Gartner of Class A Common Stock after the date
     hereof pursuant to the exercise of stock options and other rights referred
     to in clauses (iv) or (v) hereof,

<PAGE>

                                                                             23



          (viii) issuances by Gartner of Class A Common Stock after the date
     hereof and within two years following the Distribution Date (other than
     issuances excluded under clauses (vi) or (vii)) that, in the aggregate,
     amount to 1% or less of the outstanding Gartner Common Stock on the date
     hereof,

          (ix) issuances by Gartner of Class A Common Stock after the second
     anniversary of the Distribution Date, unless, in the case of any such
     issuance, such issuance was pursuant to a plan, undertaking or
     understanding adopted or entered into during such two-year period and not
     exempt under clause (viii) hereof,

          (x) transactions prior to the date hereof that are described in
     Schedule 2.6(a),

          (xi) transactions or any series of related transactions in Gartner
     Common Stock before or after the Distribution Date by any person or group
     (as defined under the Exchange Act) unless such transactions result in such
     person or group acquiring holdings of Gartner capital stock sufficient to
     allow such person or group to elect a majority of the Board of Directors of
     Gartner,

          (xii) issuances of Gartner Common Stock upon any exercise or exercises
     of the Warrants,

          (xiii) dispositions of shares of Gartner Common Stock by the holders
     thereof, or

          (xiv) any combination of the transactions described in clauses (i)
     through (xiii) of this Section 2.7(b).

     Notwithstanding the foregoing, Gartner shall not indemnify IMS HEALTH for
any IMS HEALTH Tax Liability that results from any inaccuracy or incompleteness
in any representation made by IMS HEALTH to the IRS in connection with the
requests for the IRS Ruling or the IRS Supplemental Ruling or failure by IMS
HEALTH to comply with any representation or undertaking by IMS HEALTH to the IRS
in connection with the IRS Ruling, the IRS Supplemental Ruling or any requests
therefor.

     (c) In the event the IRS Supplemental Ruling is issued providing that
grants and exercises of stock options and other stock rights under compensatory
benefit plans of Gartner will not be taken into account in applying Section
355(e)(2)(A)(ii) (the "Stock Award Relief"), then (i) the limitation of Section
2.7(b)(iv) shall be expanded to permit the unlimited grant of stock options and
other stock awards after the date hereof in the ordinary course of business and
(ii) the limitation on issuances of Class A Common Stock in Section 2.7(b)(viii)
shall be expanded from 1% or less to 3.5% or less of the outstanding Gartner
Common Stock on the Distribution Date. Gartner agrees not to seek any private
letter ruling seeking the relief sought in the IRS Supplemental Ruling request
other than a private letter ruling (i) seeking the Stock Award Relief or (ii)
providing that section (b)(4)(B) of the certificate of incorporation of Gartner
to be effective upon consummation of the Recapitalization, which relates to the
voting ability of any person or group beneficially owning 15% of more of the
outstanding shares of the Class B Common Stock, will not have any adverse effect
on the IRS Ruling and any other private letter

                                                                            24



ruling issued by the IRS to IMS HEALTH or any predecessor or former parent of
IMS HEALTH. Subject to the last sentence of this Section 2.7(c), in the event a
private letter ruling is issued by the IRS to Gartner providing the Stock Award
Relief and such ruling is in form and substance satisfactory to IMS HEALTH in
its good faith judgment, then (i) the limitation of Section 2.7(b)(iv) shall be
expanded to permit the unlimited grant of stock options and other stock awards
after the date hereof in the ordinary course of business and (ii) the limitation
on issuances of Class A Common Stock in Section 2.7(b)(viii) shall be expanded
from 1% or less to 3.5% or less of the outstanding Gartner Common Stock on the
date hereof. In no event shall Gartner file with, or otherwise make to, the IRS
a request for a private letter ruling providing for the Stock Award Relief prior
to the Distribution Date.


ARTICLE III.  INDEMNIFICATION

     SECTION III.1 Indemnification by Gartner. (a) Gartner shall indemnify,
defend and hold harmless the IMS HEALTH Indemnitees from and against any and all
Gartner Liabilities or third party allegations of Gartner Liabilities.

     (b) Gartner shall indemnify, defend and hold harmless the IMS HEALTH
Indemnitees and the shareholders of IMS HEALTH from and against any liability of
any member of the IMS HEALTH Group or any shareholder of IMS HEALTH arising from
any inaccuracy in, or failure by Gartner to comply with, any representation made
by Gartner to the IRS in connection with the requests by IMS HEALTH for the IRS
Ruling and the IRS Supplemental Ruling; provided, however, that, notwithstanding
the foregoing, Gartner shall not indemnify IMS HEALTH, any IMS HEALTH Indemnitee
or any shareholder of IMS HEALTH for any liability that results from any
inaccuracy or incompleteness in any representation made by IMS HEALTH to the IRS
in connection with requests for the IRS Ruling or the IRS Supplemental Ruling or
failure by IMS HEALTH to comply with any representation made by IMS HEALTH to
the IRS in connection with the requests for the IRS Ruling or the IRS
Supplemental Ruling.

     SECTION III.2 Indemnification by IMS HEALTH. (a) Except as otherwise
specifically set forth in any provision of this Agreement, IMS HEALTH shall
indemnify, defend and hold harmless the Gartner Indemnitees from and against any
and all IMS HEALTH Liabilities or third party allegations of IMS HEALTH
Liabilities.

     (b) IMS HEALTH shall indemnify, defend and hold harmless the Gartner
Indemnitees from and against (i) any and all federal, state and local taxes,
including any interest, penalties or additions to tax, that result solely from
the Recapitalization or from the application of Treasury Regulation Section
1.1502-6 or any similar provision of state, local or other tax law and (ii) any
liability of any member of the Gartner Group arising solely from any inaccuracy
in, or failure by IMS Health to comply with, any representation made by IMS
Health to the IRS in connection with the requests by IMS Health for the IRS
Ruling and the IRS Supplemental Ruling; provided, however, that, notwithstanding
the foregoing, IMS HEALTH shall not indemnify Gartner or any Gartner Indemnitee
for any liability that results from any inaccuracy or incompleteness in any
representation made by Gartner to the IRS in connection with requests for

<PAGE>


                                                                              25


the IRS Ruling or the IRS Supplemental Ruling or failure by Gartner to comply
with any representation made by Gartner to the IRS in connection with the
requests for the IRS Ruling or the IRS Supplemental Ruling.

     SECTION III.3 Procedures for Indemnification in Third Party Claims.

     (a) Third Party Claims. If a claim or demand is made against a Gartner
Indemnitee or an IMS HEALTH Indemnitee (each, an "Indemnitee") by any person who
is not a party to this Agreement (a "Third Party Claim") as to which such
Indemnitee is entitled to indemnification pursuant to this Agreement, such
Indemnitee shall notify the party which is or may be required pursuant to the
terms hereof to make such indemnification (the "Indemnifying Party") in writing,
and in reasonable detail, of the Third Party Claim promptly (and in any event
within 15 business days) after receipt by such Indemnitee of written notice of
the Third Party Claim; provided, however, that failure to give such notification
shall not affect the indemnification provided hereunder except to the extent the
Indemnifying Party shall have been actually prejudiced as a result of such
failure (except that the Indemnifying Party shall not be liable for any expenses
incurred during the period in which the Indemnitee failed to give such notice).
Thereafter, the Indemnitee shall deliver to the Indemnifying Party, promptly
(and in any event within five business days) after the Indemnitee's receipt
thereof, copies of all notices and documents (including court papers) received
by the Indemnitee relating to the Third Party Claim.

     If a Third Party Claim is made against an Indemnitee with respect to which
a claim for indemnification is made pursuant to Section 3.1 or Section 3.2
hereof, the Indemnifying Party shall be entitled to participate in the defense
thereof and, if it so chooses and acknowledges in writing its obligation to
indemnify the Indemnitee therefor, to assume the defense thereof with counsel
selected by the Indemnifying Party; provided that such counsel is not reasonably
objected to by the Indemnitee. Should the Indemnifying Party so elect to assume
the defense of a Third Party Claim, the Indemnifying Party shall, within 30 days
(or sooner if the nature of the Third Party Claim so requires), notify the
Indemnitee of its intent to do so, and the Indemnifying Party shall thereafter
not be liable to the Indemnitee for legal or other expenses subsequently
incurred by the Indemnitee in connection with the defense thereof; provided,
that such Indemnitee shall have the right to employ counsel to represent such
Indemnitee if, in such Indemnitee's reasonable judgment, a conflict of interest
between such Indemnitee and such Indemnifying Party exists in respect of such
claim which would make representation of both such parties by one counsel
inappropriate, and in such event the fees and expenses of such separate counsel
shall be paid by such Indemnifying Party. If the Indemnifying Party assumes such
defense, the Indemnitee shall have the right to participate in the defense
thereof and to employ counsel, subject to the proviso of the preceding sentence,
at its own expense, separate from the counsel employed by the Indemnifying
Party, it being understood that the Indemnifying Party shall control such
defense. The Indemnifying Party shall be liable for the fees and expenses of
counsel employed by the Indemnitee for any period during which the Indemnifying
Party has failed to assume the defense thereof (other than during the period
prior to the time the Indemnitee shall have given notice of the Third Party
Claim as provided above). If the Indemnifying Party so elects to assume the
defense of any Third Party Claim, all of the Indemnitees shall cooperate

<PAGE>

                                                                              26

with the Indemnifying Party in the defense or prosecution thereof, including by
providing or causing to be provided, Records and witnesses as soon as reasonably
practicable after receiving any request therefor from or on behalf of the
Indemnifying Party.

     In no event will the Indemnitee admit any liability with respect to, or
settle, compromise or discharge, any Third Party Claim without the Indemnifying
Party's prior written consent (which will not be unreasonably withheld);
provided, however, that the Indemnitee shall have the right to settle,
compromise or discharge such Third Party Claim without the consent of the
Indemnifying Party if the Indemnitee releases the Indemnifying Party from its
indemnification obligation hereunder with respect to such Third Party Claim and
such settlement, compromise or discharge would not otherwise adversely affect
the Indemnifying Party. If the Indemnifying Party acknowledges in writing
liability for a Third Party Claim (as between the Indemnifying Party and the
Indemnitee), the Indemnitee will agree to any settlement, compromise or
discharge of a Third Party Claim that the Indemnifying Party may recommend and
that by its terms obligates the Indemnifying Party to pay the full amount of the
liability in connection with such Third Party Claim and releases the Indemnitee
completely in connection with such Third Party Claim and that would not
otherwise adversely affect the Indemnitee; provided, however, that the
Indemnitee may refuse to agree to any such settlement, compromise or discharge
if the Indemnitee agrees that the Indemnifying Party's indemnification
obligation with respect to such Third Party Claim shall not exceed the amount
that would be required to be paid by or on behalf of the Indemnifying Party in
connection with such settlement, compromise or discharge. If an Indemnifying
Party elects not to assume the defense of a Third Party Claim, or fails to
notify an Indemnitee of its election to do so as provided herein, such
Indemnitee may compromise, settle or defend such Third Party Claim.

     Notwithstanding the foregoing, the Indemnifying Party shall not be entitled
to assume the defense of any Third Party Claim (and shall be liable for the fees
and expenses of counsel incurred by the Indemnitee in defending such Third Party
Claim) if the Third Party Claim seeks an order, injunction or other equitable
relief or relief for other than money damages against the Indemnitee which the
Indemnitee reasonably determines, after conferring with its counsel, cannot be
separated from any related claim for money damages. If such equitable relief or
other relief portion of the Third Party Claim can be so separated from that for
money damages, the Indemnifying Party shall be entitled to assume the defense of
the portion relating to money damages.

     (b) Subrogation. In the event of payment by an Indemnifying Party to any
Indemnitee in connection with any Third-Party Claim, such Indemnifying Party
shall be subrogated to and shall stand in the place of such Indemnitee as to any
events or circumstances in respect of which such Indemnitee may have any right
or claim relating to such Third-Party Claim against any claimant or plaintiff
asserting such Third-Party Claim. Such Indemnitee shall cooperate with such
Indemnifying Party in a reasonable manner, and at the cost and expense of such
Indemnifying Party, in prosecuting any subrogated right or claim.

                                                                            27


     (c) Remedies Not Exclusive. The remedies provided in this Article III shall
be cumulative and shall not preclude assertion by any Indemnitee of any other
rights or the seeking of any and all other remedies against any Indemnifying
Party.

     SECTION III.4 Indemnification Payments. Indemnification required by this
Article III shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or loss,
liability, claim, damage or expense is incurred.

ARTICLE IV.  COVENANTS

     SECTION IV.1 Access to Information. (a) Other than in circumstances in
which indemnification is sought pursuant to Article III (in which event the
provisions of such Article will govern), from and after the Distribution Date,
each of Gartner and IMS HEALTH shall afford to the other and its authorized
accountants, counsel and other designated representatives reasonable access
during normal business hours, subject to appropriate restrictions for
classified, privileged or confidential information, to the personnel,
properties, books and records of such party and its Subsidiaries insofar as such
access is reasonably required by the other party and relates to such other
party's performance of its obligations under this Agreement or the
Recapitalization Agreement or such party's financial, tax and other reporting
obligations.

     (b) A party providing information or access to information to the other
party under this Article IV shall be entitled to receive from the recipient,
upon the presentation of invoices therefor, payments for such amounts, relating
to supplies, disbursements and other out-of-pocket expenses, as may be
reasonably incurred in providing such information or access to information.

     SECTION IV.2 Confidentiality. Each of Gartner and its Subsidiaries and IMS
HEALTH and its Subsidiaries shall keep, and shall cause its employees,
consultants, advisors and agents to keep, confidential all information
concerning the other parties in its possession, its custody or under its control
(except to the extent that (A) such information is then in the public domain
through no fault of such party or (B) such information has been lawfully
acquired from other sources by such party or (C) this Agreement or the
Recapitalization Agreement or any other agreement entered into pursuant hereto
or thereto permits the use or disclosure of such information) to the extent such
information (i) relates to or was acquired during the period up to the Effective
Time or pursuant to Section 4.1, or (ii) is based upon or is derived from
information described in the preceding clause (i), and each party shall not
(without the prior written consent of the other) otherwise release or disclose
such information to any other person, except such party's auditors and
attorneys, unless compelled to disclose such information by judicial or
administrative process or unless such disclosure is required by law and such
party has used commercially reasonable efforts to consult with the other

     SECTION IV.3 Standstill. (a) Subject to Sections 4.3(b) and 4.3(c), each of
IMS HEALTH and Gartner agree not to solicit, initiate or encourage the
commencement of negotiations or continue any current negotiations regarding any
proposal for the acquisition by any third party of any shares of capital stock
of Gartner (other than issuances of common stock by Gartner pursuant to employee
stock plans in the ordinary course of business) or the acquisition of Gartner
through any other means including a merger or purchase of assets (an
"Acquisition Proposal") until the earlier to occur of the termination of this
Agreement or the time at which the Distribution is consummated; provided,
however, that IMS HEALTH may respond to any unsolicited inquiries or proposals
solely to indicate that it is bound by this Section 4.3.

     (b) IMS HEALTH shall be relieved of its obligations under Section 4.3(a) if
any of the following occur:

          (i) Gartner fails to comply with its obligations with respect to the
     Financing Commitments set forth in Section 2.3 hereof in a manner that
     would reasonably be expected to permit consummation of the Distribution (A)
     on or prior to July 31, 1999 or (B) if, without violation of the foregoing,
     the Distribution is not consummated by such date, as promptly as possible
     thereafter;

          (ii) Gartner fails to comply with Section 2.2(d) herein;

          (iii) Gartner fails to use commercially reasonable efforts to obtain
     the approval for listing of the Class B Common Stock on the NYSE in a
     manner that would reasonably be expected to permit consummation of the
     Distribution (A) on or prior to July 31, 1999 or (B) if, without violation
     of the foregoing, the Distribution is not consummated by such date, as
     promptly as possible thereafter;

          (iv) Gartner fails to use commercially reasonable efforts to obtain
     clearance from the SEC to mail the Proxy Statement as promptly as
     practicable after the date hereof;

          (v) Gartner fails to use commercially reasonable efforts to call a
     special meeting of stockholders to seek approval of the Recapitalization
     and the Governance Proposals to be held on or prior to July 16, 1999,
     except that the meeting so noticed may be adjourned solely to the extent
     necessary to obtain sufficient votes for approval;

          (vi) Pursuant to Section 4.3(c)(ii), Gartner takes any action that
     would otherwise be prohibited by Section 4.3(a); provided, however, if
     Gartner takes any action permitted under Section 4.3(c)(ii) to evaluate any
     Acquisition Proposal and Gartner promptly provides to IMS HEALTH (A) copies
     of any correspondence and other documents received from the person making
     such Acquisition

<PAGE>

                                                                             29




     Proposal (including the identity of such person, but excluding confidential
     business information of such person provided for due diligence unless IMS
     HEALTH executes an appropriate nondisclosure agreement acceptable to such
     person making the Acquisition Proposal), (B) copies of analyses, advice and
     other information provided in writing to the Board of Directors of Gartner
     in connection with such Acquisition Proposal, (C) copies of analyses,
     advice and other information provided in writing to management of Gartner
     by financial advisors to Gartner in connection with such Acquisition
     Proposal, (D) any advice regarding any revised proposal provided to Gartner
     by the person making such Acquisition Proposal (other than changes in terms
     or structure that are not material), and (E) any determination made by the
     Board of Directors of Gartner in response to such proposal, then IMS HEALTH
     shall not be relieved of its obligations under Section 4.3(a) until the
     earliest of (x) any public disclosure by the Gartner Board of Directors'
     approval or recommendation of any Acquisition Proposal, (y) any public
     disclosure by the Gartner Board of Directors of the withdrawal of its
     approval or recommendation of any of the transactions contemplated hereby
     or by the Recapitalization Agreement or (z) ten business days from receipt
     by Gartner of the Acquisition Proposal; provided further that IMS HEALTH
     shall not be ------- relieved of its obligations under Section 4.3(a) if,
     prior to the expiration of such 10-business day period, Gartner shall have
     ceased to evaluate, discuss or negotiate or take any other action with
     respect to such Acquisition Proposal and delivers to IMS HEALTH a
     certificate executed by an executive officer of Gartner to the foregoing
     effect;

          (vii) Gartner fails (x) to take any affirmative action or consummate
     any affirmative transaction specified by the terms of the IRS Ruling, the
     request for the IRS Supplemental Ruling or, if granted prior to such time,
     the IRS Supplemental Ruling or (y) takes any action or pursues any
     transaction (other than any action or transaction contemplated by this
     Agreement) or fails to take any actions or consummate any transaction which
     would reasonably be expected to adversely affect the IRS Ruling, the
     request for the IRS Supplemental Ruling or, if granted prior to such time,
     the IRS Supplemental Ruling;

         (viii) Gartner fails to use commercial reasonable efforts to obtain the
     approval of its stockholders of the Recapitalization or takes any action or
     makes any public statement inconsistent with the foregoing; or

<PAGE>


                                                                             30



          (ix) Gartner breaches or fails to comply with any of its material
     obligations set forth in this Agreement or the Recapitalization Agreement
     and fails to cure such breach or failure within 15 days following notice
     from IMS HEALTH.

     (c) Gartner shall be relieved of its obligations under Section 4.3(a) if:

          (i) IMS HEALTH breaches or fails to comply with any of its material
     obligations set forth in this Agreement or the Recapitalization Agreement
     and fails to cure such breach or failure within 15 days following notice
     from Gartner; or

          (ii) After receipt of a bona fide written Acquisition Proposal, the
     Board of Directors of Gartner in good faith determines, based upon the
     advice of its outside counsel regarding the Board's duties, that the Board
     will breach its fiduciary duties to stockholders of Gartner if it does not
     commence discussions or negotiations with the person making such
     Acquisition Proposal.

     SECTION IV.4 Public Announcements. Each of IMS HEALTH and Gartner agrees
that no public release or announcement concerning the Recapitalization, Cash
Dividend, or Stock Repurchase shall be issued by either party without the prior
written consent of the other (which shall not be unreasonably withheld), except
as such release or announcement may be required by law or the rules or
regulations of any United States securities exchange, in which case the party
required to make the release or announcement shall use its commercially
reasonable efforts to allow each other party reasonable time to comment on each
release or announcement in advance of such issuance.

     SECTION IV.5 Required Consents. Each of IMS HEALTH and Gartner shall use
commercially reasonable efforts to obtain all of the consents, waivers or
authorizations required in connection with the completion of the
Recapitalization and the Distribution as are listed on Schedule 4.5 (the
"Required Consents").


ARTICLE V.  DISPUTE RESOLUTION

     SECTION V.1 Negotiation. In the event of a controversy, dispute or claim
arising out of, in connection with, or in relation to the interpretation,
performance, nonperformance, validity or breach of this Agreement or the
Recapitalization Agreement or otherwise arising out of, or in any way related to
this Agreement or the Recapitalization Agreement or the transactions
contemplated hereby and thereby, including any claim based on contract, tort,
statute or constitution (but excluding any controversy, dispute or claim between
a party hereto and a third-party beneficiary hereof) (collectively, "Agreement
Disputes"), the general counsels of the parties shall negotiate in good faith
for a reasonable period of time to settle such Agreement Dispute, provided such
reasonable period shall not, unless otherwise

<PAGE>

                                                                             31



agreed by the parties in writing, exceed 30 days from the time the parties began
such negotiations; provided further that in the event of any arbitration in
accordance with Section 5.2 hereof, the parties shall not assert the defenses of
statute of limitations and laches arising for the period beginning after the
date the parties began negotiations hereunder, and any contractual time period
or deadline under this Agreement or the Recapitalization Agreement to which such
Agreement Dispute relates shall not be deemed to have passed until such
Agreement Dispute has been resolved.

     SECTION V.2 Arbitration. If after such reasonable period such general
counsels are unable to settle such Agreement Dispute (and in any event, unless
otherwise agreed in writing by the parties, after 60 days have elapsed from the
time the parties began such negotiations), such Agreement Dispute shall be
determined, at the request of any party, by arbitration conducted in New York
City, before and in accordance with the then-existing International Arbitration
Rules of the American Arbitration Association (the "Rules"). In any dispute
between the parties hereto, the number of arbitrators shall be one. Any judgment
or award rendered by the arbitrator shall be final, binding and nonappealable
(except upon grounds specified in 9 U.S.C. ss.10(a) as in effect on the date
hereof). If the parties are unable to agree on the arbitrator, the arbitrator
shall be selected in accordance with the Rules; provided that the arbitrator
shall be a U.S. national. Any controversy concerning whether an Agreement
Dispute is an arbitrable Agreement Dispute, whether arbitration has been waived,
whether an assignee of this Agreement is bound to arbitrate, or as to the
interpretation of enforceability of this Article V shall be determined by the
arbitrator. In resolving any dispute, the parties intend that the arbitrator
apply the substantive laws of the State of New York, without regard to the
choice of law principles thereof. The parties intend that the provisions to
arbitrate set forth herein be valid, enforceable and irrevocable. The parties
agree to comply with any award made in any such arbitration proceeding that has
become final in accordance with the Rules and agree to enforcement of or entry
of judgment upon such award, by any court of competent jurisdiction, including
(a) the Supreme Court of the State of New York, New York County, or (b) the
United States District Court for the Southern District of New York, in
accordance with Section 6.17 hereof. The arbitrator shall be entitled, if
appropriate, to award any remedy in such proceedings, including monetary
damages, specific performance and all other forms of legal and equitable relief;
provided, however, the arbitrator shall not be entitled to award punitive
damages. Without limiting the provisions of the Rules, unless otherwise agreed
in writing by or among the parties or permitted by this Agreement, the parties
shall keep confidential all matters relating to the arbitration or the award,
provided such matters may be disclosed (i) to the extent reasonably necessary in
any proceeding brought to enforce the award or for entry of a judgment upon the
award and (ii) to the extent otherwise required by law. Notwithstanding Article
32 of the Rules, the party other than the prevailing party in the arbitration
shall be responsible for all of the costs of the arbitration, including legal
fees and other costs specified by such Article 32. Nothing contained herein is
intended to or shall be construed to prevent any party, in accordance with
Article 22(3) of the Rules or otherwise, from applying to any court of competent
jurisdiction for interim measures or other provisional relief in connection with
the subject matter of any Agreement Disputes.

     SECTION V.3 Continuity of Service and Performance. Unless otherwise agreed
in writing, the parties will continue to provide service and honor all other
commitments under this Agreement, the Transition Services Agreement, and the
Recapitalization Agreement during

<PAGE>

                                                                             32



the course of dispute resolution pursuant to the provisions of this Article V
with respect to all matters not subject to such dispute, controversy or claim.

ARTICLE VI.  INSURANCE

     SECTION VI.1 Separation of Insurance Coverages. Gartner shall take all
reasonable steps necessary and appropriate to have in effect, on or prior to the
Distribution Date or as soon thereafter as reasonably practicable, separate
Policies in respect of Gartner Liabilities (including without limitation
Liabilities which exist on the date of this Agreement or which arise prior to
the Effective Time) to replace any insurance coverage provided to Gartner and
its Subsidiaries under the Shared Policies.

     SECTION VI.2 Policy Rights. Each of IMS HEALTH and Gartner shall retain any
and all rights of an insured party under each of the remaining Shared Policies,
subject to the terms of such Shared Policies and any limitations or obligations
contemplated by this Article VI, specifically including rights of indemnity and
the right to be defended by or at the expense of the insurer, with respect to
all claims, suits, actions, proceedings, injuries, losses, liabilities, damages
and expenses incurred or claimed to have been incurred on or prior to the
Distribution Date, and which claims, suits, actions, proceedings, injuries,
losses, liabilities, damages and expenses may arise out of an insured or
insurable occurrence under one or more of such Shared Policies.

            SECTION VI.3 Post-Distribution Date Claims. (a) Administration.
After the Distribution Date, IMS HEALTH shall be responsible for (i) Insurance
Administration of the Shared Policies and (ii) Claims Administration under such
Shared Policies with respect to Gartner Liabilities and IMS HEALTH Liabilities;
provided that the assumption of such responsibilities by IMS HEALTH is in no way
intended to limit, inhibit or preclude any right to insurance coverage for any
Insured Claim of a named insured under such Policies as contemplated by the
terms of this Agreement; provided further that IMS HEALTH's assumption of the
administrative responsibilities for the Shared Policies shall not relieve the
party submitting any Insured Claim of the primary responsibility for reporting
such Insured Claim accurately, completely and in a timely manner or of such
party's authority to settle any such Insured Claim within any period permitted
or required by the relevant Policy; and provided further that all direct or
indirect communication with insurers relating to the Shared Policies shall be
conducted by IMS HEALTH. IMS HEALTH may discharge its administrative
responsibilities under this Section 6.3 by contracting for the provision of
services by independent parties. Each of the parties hereto shall administer and
pay any costs relating to defending its respective Insured Claims under Shared
Policies to the extent such defense costs are not covered under such Policies
and shall be responsible for obtaining or reviewing the appropriateness of
releases upon settlement of its respective Insured Claims under Shared Policies.
The disbursements, out-of-pocket expenses and direct and indirect costs of
employees or agents of IMS HEALTH relating to Claims Administration and
Insurance Administration contemplated by this Section 6.3(a) shall be treated in
accordance with the terms of the Transition Services Agreement, if still in
effect with respect to insurance and risk management, or, if the Transition
Services Agreement shall no

<PAGE>

                                                                             33




longer be in effect with respect to insurance and risk management, then each of
Gartner and IMS HEALTH shall be responsible for its own Claims Administration
and Insurance Administration.

     (b) Exceeding Policy Limits. Gartner and IMS HEALTH shall not be liable to
one another for claims not reimbursed by insurers for any reason not within the
control of Gartner or IMS HEALTH, as the case may be, including coinsurance
provisions, deductibles, quota share deductibles, self-insured retentions,
bankruptcy or insolvency of an insurance carrier, Shared Policy limitations or
restrictions, any coverage disputes, any failure to timely claim by Gartner or
IMS HEALTH or any defect in such claim or its processing.

     (c) Allocation of Insurance Proceeds. Insurance Proceeds received with
respect to claims, costs and expenses under the remaining Shared Policies shall
be paid to IMS HEALTH, which shall thereafter administer such Policies by paying
the Insurance Proceeds to Gartner with respect to Gartner Liabilities and by
retaining the Insurance Proceeds with respect to IMS HEALTH Liabilities. Payment
of the allocable portions of Insurance Proceeds resulting from such Policies
will be made by IMS HEALTH to Gartner as appropriate upon receipt from the
insurance carrier (except as provided below in subclause (B) of clause (ii) of
this Section 6.3(c)) and following consultation with Gartner. In the event that
the aggregate limits on any Shared Policies are exceeded by the aggregate of
outstanding Insured Claims by both of the parties hereto, the parties agree: (i)
to allocate the first $150 million (or, to the extent the aggregate limits on
such Shared Policies are reinstated, $150 million plus such amount reinstated)
of Insurance Proceeds received based upon the respective percentage of the total
of their premiums paid for Shared Policies, except that in no event shall a
party be entitled to Insurance Proceeds in excess of its Insured Claims and any
amount recovered by such party in excess of such Insured Claims shall be
available to the other party to the extent of its Insured Claims; and (ii) that
all Insurance Proceeds in excess of $150 million (or, to the extent the
aggregate limits on such Shared Policies are reinstated, $150 million plus such
amount reinstated) shall be payable to and retained by IMS HEALTH: (A) first, to
the full extent of any Insured Claims of IMS HEALTH not satisfied by the first
$150 million (or, to the extent the aggregate limits on such Shared Policies are
reinstated, $150 million plus such amount reinstated) of Insurance Proceeds; and
(B) second, to the full extent of any Insured Claims of Gartner, to be paid to
Gartner only when and to the extent that (1) the aggregate Insurance Proceeds
received by IMS Health in excess of $150 million (or, to the extent the
aggregate limits on such Shared Policies are reinstated, $150 million plus such
amount reinstated) exceed the sum of (A) the aggregate amount of such proceeds
that have been paid to IMS Health in respect of Insured Claims of IMS Health
(not Gartner) and (B) the aggregate amount of Insured Claims of IMS Health (not
Gartner) that (x) IMS Health has previously submitted to the insurance carrier
or carriers, (y) have not yet been paid to IMS Health, and (z) IMS Health
continues to claim a right to receive payment on; and (2) it would be impossible
for IMS Health to submit additional Insured Claims under the Shared Policies.
Any party who has received Insurance Proceeds in excess of such party's
allocable portion of Insurance Proceeds shall pay to the other party the
appropriate amount so that each party will have received its allocable portion
of Insurance Proceeds pursuant hereto. Each of the parties agrees to use
commercially reasonable efforts to maximize available coverage under those
Shared Policies applicable to it, and to take all commercially reasonable steps
to recover from all other responsible parties in respect of an

<PAGE>

                                                                             34



Insured Claim to the extent coverage limits under a Shared Policy have been
exceeded or would be exceeded as a result of such Insured Claim.

     (d) Allocation of Deductibles. In the event that both parties have bona
fide claims under any Shared Policy for which an aggregate deductible is
reached, the parties agree that the aggregate amount of the deductible paid
shall be borne by the parties in the same proportion which the Insurance
Proceeds received by any such party (without giving effect to any deductible)
bears to the total Insurance Proceeds received under the applicable Shared
Policy, and any party who has paid more than such share of the deductible shall
be entitled to receive from the other party an appropriate amount so that each
party has borne its allocable share of the deductible pursuant hereto.

     SECTION VI.4 Agreement for Waiver of Conflict and Shared Defense. In the
event that Insured Claims of both of the parties hereto exist relating to the
same occurrence, the parties shall jointly defend and waive any conflict of
interest necessary to the conduct of the joint defense. Nothing in this Article
VI shall be construed to limit or otherwise alter in any way the obligations of
the parties to this Agreement, including those created by this Agreement, by
operation of law or otherwise.

     SECTION VI.5 Cooperation. The parties agree to use their commercially
reasonable efforts to cooperate with respect to the various insurance matters
contemplated by this Agreement.


ARTICLE VII.  MISCELLANEOUS

     SECTION VII.1 Complete Agreement; Construction. This Agreement and the
Recapitalization Agreement, including the Exhibits and Schedules hereto and
thereto, shall constitute the entire agreement between the parties with respect
to the subject matter hereof and thereof and shall supersede all previous
negotiations, commitments and writings with respect to such subject matter.

     SECTION VII.2 Counterparts. This Agreement may be executed in one or more

Dear Sirs:

     Reference is made to (i) the Distribution Agreement (the "1996 Distribution
Agreement"), dated as of October 28, 1996, among Cognizant Corporation, which
has been renamed Nielsen Media Research, Inc. ("NMR"), The Dun & Bradstreet
Corporation, which has been renamed the R.H. Donnelley Corporation ("RHD") and
ACNielsen Corporation ("ACNielsen") and (ii) the letter of undertaking dated
June 29, 1998 from IMS Health Incorporated ("IMS HEALTH") to RHD and ACNielsen.
In June 1998, NMR distributed to its stockholders all of the outstanding shares
of common stock of IMS HEALTH (the "IMS HEALTH Distribution"). IMS HEALTH has
announced its intention to distribute (the "Gartner Distribution") to its
stockholders all of the shares of the Class B Common Stock of Gartner Group,
Inc. ("Gartner") that IMS HEALTH will hold following the recapitalization of
Gartner contemplated by the Merger Agreement dated June 17, 1999, between
Gartner and GRGI, INC. In connection with the IMS HEALTH Distribution, IMS
HEALTH undertook (the "IMS HEALTH Undertaking") to both RHD and ACNielsen to be
jointly and severally liable for all Cognizant Liabilities (as defined in the
1996 Distribution Agreement). Under Section 8.9(c) of the 1996 Distribution
Agreement, as applicable to IMS HEALTH pursuant to the IMS HEALTH Undertaking,
IMS HEALTH may not make a distribution such as the Gartner Distribution unless
it causes the distributed entity to undertake to both RHD and ACNielsen to be
jointly and severally liable for all Cognizant Liabilities under the 1996
Distribution Agreement. Therefore, in accordance with Section 8.9(c) of the 1996
Distribution Agreement and intending to be legally bound hereby, from and after
the effective time of the Gartner Distribution, Gartner undertakes to each of
RHD and ACNielsen to be jointly and severally liable for all Cognizant
Liabilities under the 1996 Distribution Agreement.

    Very truly yours,

    GARTNER GROUP, INC.

Dear Sirs:

     Reference is made to the Distribution Agreement (the "1998 Distribution
Agreement"), dated as of June 30, 1998, among Cognizant Corporation, which has
been renamed Nielsen Media Research, Inc. ("NMR"), and IMS Health Incorporation

entity to undertake to NMR to be jointly and severally liable for all IMS HEALTH
Liabilities under the 1998 Distribution Agreement. Therefore, in accordance with
Section 8.9(c) of the 1998 Distribution Agreement and intending to be legally
bound hereby, from and after the effective time of the Gartner Distribution,
Gartner undertakes to NMR to be jointly and severally liable for all IMS HEALTH
Liabilities under the 1998 Distribution Agreement.

            WHEREAS, IMS HEALTH has agreed, subject to certain conditions, to
distribute all the shares of Class B Common Stock, on a pro rata basis, to the
holders of the common stock of IMS HEALTH promptly following consummation of the

convene and hold, a meeting of its stockholders (the "Stockholders Meeting") for
the purpose of considering, as three separate proposals, (i) the approval of the

Distribution Agreement); (ii) the approval of amendments to the Company's
Certificate of Incorporation providing for the proposed classified board,

"Governance Provisions"); and (iii) the approval of amendments to the Company's
Certificate of Incorporation providing for the increase of authorized stock
which the Company may issue as set forth in Exhibits A-1(a) and A-1(b) hereto to

recommend to its stockholders approval of the Merger and this Agreement and
shall not withdraw such recommendation; provided, however, that the Company's

Certificate of Incorporation, but only as amendments to become effective solely
upon the effectiveness of the Merger. The Company shall use all reasonable
efforts to have the Proxy Statement cleared by the SEC for mailing in definitive
form as promptly as practicable after such filing. The Company and IMS

                    CERTIFICATE OF INCORPORATION AMENDMENTS
                          (WITH GOVERNANCE PROVISIONS)


            The Certificate of Incorporation of the Company in effect
immediately prior to the Effective Time (the "Existing Certificate of
Incorporation") shall be amended by deleting in its entirety Article IV thereof
and replacing it with the following1:

                                   "ARTICLE IV

                  (a) Authorized Stock. The Corporation is authorized to issue
      two classes of stock to be designated, respectively, "common stock" and
      "preferred stock." The total number of shares which this corporation is
      authorized to issue is two hundred four million, one hundred thousand
      (204,100,000) shares [two hundred fifty-five million (255,000,000)
      shares]*. Two hundred one million, six hundred thousand (201,600,000) [Two

      hundred sixty thousand (120,960,000) [one hundred sixty-six million
      (166,000,000)]* shares shall be designated Class A Common Stock (the
      "Class A Common Stock") and eighty million, six hundred forty thousand
      (80,640,000) [eighty-four million (84,000,000)]* shares shall be
      designated Class B Common Stock (the "Class B Common Stock"). Two million,
      five hundred thousand (2,500,000) [Five million (5,000,000)]* shares shall
      be designated preferred stock (the "Preferred Stock"), all of which are
      presently undesignated as to series. Each share of Preferred Stock shall

      Common Stock shall be identical in all respects, except as otherwise
      expressly provided herein, and the relative powers, preferences, rights,
      qualifications, limitations and restrictions of the shares of Class A
      Common Stock and Class B Common Stock shall be as follows:

            (1) Cash or Property Dividends. Subject to the rights and
      preferences of the Preferred Stock as set forth in any resolution or
      resolutions of the Board of Directors providing for the issuance of such
      stock pursuant to this Article IV, and except as otherwise provided for
      herein, the holders of Class A Common Stock and Class B

   of Merger.

                                                                               2

      Common Stock are entitled to receive dividends out of assets legally
      available therefor at such times and in such per share amounts as the
      Board of Directors may from time to time determine; provided that whenever
      a cash dividend is paid, the same amount shall be paid in respect of each
      outstanding share of Class A Common Stock and Class B Common Stock.

            (2) Stock Dividends. If at any time a dividend is to be paid in
      shares of Class A Common Stock or shares of Class B Common Stock (a "stock
      dividend"), such stock dividend may be declared and paid only as follows:
      only Class A Common Stock may be paid to holders of Class A Common Stock
      and only Class B Common Stock may be paid to holders of Class B Common
      Stock, and whenever a stock dividend is paid, the same rate or ratio of
      shares shall be paid in respect of each outstanding share of Class A
      Common Stock and Class B Common Stock.

            (3) Stock Subdivisions and Combinations. The Corporation shall not
      subdivide, reclassify or combine stock of either class of Common Stock
      without at the same time making a proportionate subdivision or combination
      of the other class.

            (4) Voting. Voting power shall be divided between the classes and
      series of stock as follows:

                  (A) With respect to the election of directors, holders of
      Class A Common Stock and holders of Voting Preferred Stock (as defined
      below), voting together, shall be entitled to elect that number of
      directors which constitutes 20% of the authorized number of members of the
      Board of Directors (or, if such 20% is not a whole number, then the
      nearest lower whole number of directors that is closest to 20% of such
      membership) (the "Class A Directors"). Each share of Class A Common Stock
      shall have one vote in the election of the Class A Directors and each
      share of Voting Preferred Stock shall have a number of votes in the
      election of the Class A Directors as specified in the resolution of the
      Board of Directors authorizing such Voting Preferred Stock. Holders of
      Class B Common Stock shall be entitled to elect the remaining directors
      (the "Class B Directors"). Each share of Class B Common Stock shall have
      one vote in the election of such directors. For purposes of this Section
      (b)(4) and Section (b) (5) of this Article IV, references to the
      authorized number of members of the Board of Directors (or the remaining
      directors) shall not include any directors which the holders of any shares
      of Preferred Stock may have the right to elect upon the failure of the
      Corporation to pay regular dividends on such Preferred Stock as and when
      due for a specified period of time. For purposes of this Section (b)(4),
      "Special Voting Rights" means the different voting rights of the holders
      of Class A Common Stock, holders of Class B Common Stock and holders of
      Voting Preferred Stock with respect to the election of the applicable
      percentage of the authorized number of members of the Board of Directors
      as described in this Section (b)(4)(A). "Voting Preferred Stock" means
      shares of each series of Preferred Stock upon which the right to vote for
      directors has been conferred in accordance with Section (c) of this
      Article IV, except for any right to elect directors which may be provided
      upon the failure of the Corporation to pay regular dividends on such
      Preferred Stock as and when due for a specified period of time.

                                                                               3

                  (B) Subject to the last sentence of this Section (b)(4)(B),
      notwithstanding anything to the contrary contained in Section (a)(4)(A) of
      this Article IV, for so long as any person or entity or group of persons
      or entities acting in concert beneficially own 15% or more of the
      outstanding shares of Class B Common Stock, then in any election of
      directors or other exercise of voting rights with respect to the election
      or removal of directors, such person, entity or group shall only be
      entitled to vote (or otherwise exercise voting rights with respect to) a
      number of shares of Class B Common Stock that constitutes a percentage of
      the total number of shares of Class B Common Stock then outstanding which
      is less than or equal to such person, entity or group's Entitled Voting
      Percentage. For the purposes hereof, a person, entity or group's "Entitled
      Voting Percentage" at any time shall mean the percentage of the then
      outstanding shares of Class A Common Stock beneficially owned by such
      person, entity or group at such time. For purposes of this Section
      (b)(4)(B), a "beneficial owner" of Common Stock includes any person or
      entity or group of persons or entities who, directly or indirectly,
      including through any contract, arrangement, understanding, relationship
      or otherwise, written or oral, formal or informal, control the voting
      power (which includes the power to vote or to direct the voting) of such
      Common Stock. The provisions of this Section (b)(4)(B) shall be effective
      only following (i) the distribution by IMS Health Incorporated ("IMS
      HEALTH") to its stockholders of all of the Class B Common Stock owned by
      it, (ii) the receipt of a private letter ruling from the Internal Revenue
      Service (the "IRS") to the effect that the terms of this Section (b)(4)(B)
      will not have any adverse effect on the private letter ruling issued by
      the IRS to IMS HEALTH on April 14, 1999 and any other private letter
      ruling issued by the IRS to IMS HEALTH or any predecessor or former parent
      of IMS HEALTH and (iii) the approval of the terms of this Section
      (b)(4)(B) by the New York Stock Exchange, Inc. or any other national
      securities exchange or automated quotation service on which the Common
      Stock is then listed or admitted for trading.

                  (C) Any Class A Director may be removed only for cause, by a
      vote of a majority of the votes held by the holders of Class A Common
      Stock and holders of Voting Preferred Stock, voting together as a class.
      Any Class B Director may be removed only for cause, by a vote of a
      majority of the votes held by the holders of Class B Common Stock, voting
      separately as a class.

                  (D) Except as otherwise specified herein, the holders of Class
      A Common Stock and holders of Class B Common Stock (i) shall in all
      matters not otherwise specified in this Section (b)(4) of this Article IV
      vote together (including, without limitation, with respect to increases or
      decreases in the authorized number of shares of any class of Common
      Stock), with each share of Class A Common Stock and Class B Common Stock
      having one vote, and (ii) shall be entitled to vote as separate classes
      only when required by law to do so under mandatory statutory provisions
      that may not be excluded or overridden by a provision in the Certificate
      of Incorporation or as provided herein.

                                                                               4

                  (E) Except as set forth in this Section (b)(4) of this Article
      IV, the holders of Class A Common Stock shall have exclusive voting power
      (except for any voting powers of any Preferred Stock) on all matters at
      any time when no Class B Common Stock is issued and outstanding, and the
      holders of Class B Common Stock shall have exclusive voting power (except
      for any voting powers of any Preferred Stock) on all matters at any time
      when no Class A Common Stock is issued and outstanding.

            (5) Vacancies; Increase or Decreases in Size of the Board of
      Directors. Any vacancy in the office of a director created by the death,
      resignation or removal of a director elected by (or appointed on behalf
      of) the holders of the Class B Common Stock or the holders of the Class A
      Common Stock and Voting Preferred Stock voting together as a class, as the
      case may be, may be filled by the vote of the majority of the directors
      (or the sole remaining director) elected by (or appointed on behalf of)
      such holders of Class B Common Stock or Class A Common Stock and Voting
      Preferred Stock (or on behalf of whom that director was appointed), as the
      case may be, whose death, resignation or removal created the vacancy,
      unless there are no such directors, in which case such vacancy may be
      filled by the vote of the majority of the directors or by the sole
      remaining director, regardless, in each instance, of any quorum
      requirements set out in the By-laws. Any director elected by some or all
      of the directors to fill a vacancy shall hold office for the remainder of
      the full term of the director whose vacancy is being filled and until such
      director's successor shall have been elected and qualified unless removed
      and replaced pursuant to Section (b)(4)(C) of this Article IV and this
      Section (b)(5). All newly-created directorships resulting from an increase
      in the authorized number of directors shall be allocated between Class A
      Directors and Class B Directors such that at all times the number of
      directorships reserved for Class A Directors shall be 20% of the
      authorized number of members of the Board of Directors (or, if such 20% is
      not a whole number, then the nearest lower whole number of directors that
      is closest to 20% of such membership) and the remaining directorships are
      reserved for Class B Directors. No decrease in the number of directors
      constituting the Board of Directors shall shorten the term of any
      incumbent director. If the number of directors is changed, any increase or
      decrease shall be apportioned among the classes of directors established
      pursuant to Article V so that the number of directors in each class is as
      nearly equal as possible.

            (6) Merger or Consolidation. In case of any consolidation of the
      Corporation with one or more other corporations or a merger of the
      Corporation with another corporation, each holder of a share of Class A
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class B Common Stock, and each holder of a share of Class B
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class A Common Stock; provided that, in any such
      transaction, the holders of shares of Class A Common Stock and the holders
      of shares of Class B Common Stock may receive different kinds of shares of
      stock if the only difference in such shares is the inclusion of voting
      rights which continue the Special Voting Rights.

                                                                               5

            (7) Liquidation. In the event of any liquidation, dissolution or
      winding up of the Corporation, the holders of the Class A Common Stock and
      Class B Common Stock shall participate equally per share in any
      distribution to stockholders, without distinction between classes.

                  (c) Preferred Stock. Any Preferred Stock not previously
      designated as to series may be issued from time to time in one or more
      series pursuant to a resolution or resolutions providing for such issue
      duly adopted by the Board of Directors (authority to do so being hereby
      expressly vested in the Board), and such resolution or resolutions shall
      also set forth the voting powers, full or limited or none, of each such
      series of Preferred Stock and shall fix the designations, preferences and
      relative, participating, optional or other special rights and
      qualifications, limitations or restrictions of each such series of
      Preferred Stock; provided that, except for any right to elect directors
      upon the failure of the Corporation to pay regular dividends on such
      Preferred Stock as and when due for a specified period of time, no series
      of Preferred Stock shall be entitled to vote generally in the election of
      any directors of the Corporation other than Class A Directors or to vote
      separately to elect one or more directors of the Corporation. The Board of
      Directors is authorized to alter the designation, rights, preferences,
      privileges and restrictions granted to or imposed upon any wholly unissued
      series of Preferred Stock and, within the limits and restrictions stated
      in any resolution or resolutions of the Board of Directors originally
      fixing the number of shares constituting any series of Preferred Stock, to
      increase or decrease (but not below the number of shares of any such
      series than outstanding) the number of shares of any such subsequent to
      the issue of shares of that series.

                  Each share of Preferred Stock issued by the Corporation, if
      reacquired by the Corporation (whether by redemption, repurchase,
      conversion to Common Stock or other means), shall upon such reacquisition
      resume the status of authorized and unissued shares of Preferred Stock,
      undesignated as to series and available for designation and issuance by
      the Corporation in accordance with the immediately preceding paragraph."

            The Existing Certificate of Incorporation shall be amended by
deleting in its entirety Article V thereof and replacing it with the following:

                                   "ARTICLE V

                  The directors, other than those who may be elected solely by
      the holders of any class or series of Preferred Stock, if any, shall be
      classified, with respect to the time for which they severally hold office,
      into three classes, as nearly equal in number as possible, as determined
      by the Board of Directors, one class ("Class I") to hold office initially
      for a term expiring at the first annual meeting of stockholders to be held
      after the date this Article V becomes effective (the "Classified Board
      Effective Date"), another class ("Class II") to hold office initially for
      a term expiring at the second annual meeting of stockholders to be held
      after the Classified Board Effective Date, and another class ("Class III")
      to hold office initially for a term expiring at the third annual meeting
      of

      stockholders to be held after the Classified Board Effective Date, with
      the members of each class to hold office until their successors are
      elected and qualified. Directors elected by a class or series of stock, or
      if applicable, classes or series of stock voting together, shall be
      divided as evenly as possible, and shall be allocated by the Board of
      Directors, among Class I, Class II and Class III. At each annual meeting
      of stockholders, the successors of the class of directors whose term
      expires at that meeting shall be elected to hold office for a term
      expiring at the annual meeting of stockholders held in the third year
      following the year of their election."

      (the "Class B Directors"). Each share of Class B Common Stock shall have
      one vote in the election of such directors. For purposes of this Section
      (b)(4) and Section (b) (5) of this Article IV, references to the
      authorized number of members of the Board of Directors (or the remaining
      directors) shall not include any directors which the holders of any shares
      of Preferred Stock may have the right to elect upon the failure of the
      Corporation to pay regular dividends on such Preferred Stock as and when
      due for a specified period of time. For purposes of this Section (b)(4),
      "Special Voting Rights" means the different voting rights of the holders
      of Class A Common Stock, holders of Class B Common Stock and holders of
      Voting Preferred Stock with respect to the election of the applicable
      percentage of the authorized number of members of the Board of Directors
      as described in this Section (b)(4)(A). "Voting Preferred Stock" means
      shares of each series of Preferred Stock upon which the right to vote for
      directors has been conferred in accordance with Section (c) of this
      Article IV, except for any right to elect directors which may be provided
      upon the failure of the Corporation to pay regular dividends on such
      Preferred Stock as and when due for a specified period of time.

                  (B) Subject to the last sentence of this Section (b)(4)(B),
      notwithstanding anything to the contrary contained in Section (a)(4)(A) of
      this Article IV, for so long as any person or entity or group of persons
      or entities acting in concert beneficially own 15% or more of the
      outstanding shares of Class B Common Stock, then in any election of
      directors or other exercise of voting rights with respect to the election
      or removal of directors, such person, entity or group shall only be
      entitled to vote (or otherwise exercise voting rights with respect to) a
      number of shares of Class B Common Stock that constitutes a percentage of
      the total number of shares of Class B Common Stock then outstanding which
      is less than or equal to such person, entity or group's Entitled Voting
      Percentage. For the purposes hereof, a person, entity or group's "Entitled
      Voting Percentage" at any time shall mean the percentage of the then
      outstanding shares of Class A Common Stock beneficially owned by such
      person, entity or group at such time. For purposes of this Section
      (b)(4)(B), a "beneficial owner" of Common Stock includes any person or
      entity or group of persons or entities who, directly or indirectly,
      including through any contract, arrangement, understanding, relationship
      or otherwise, written or oral, formal or informal, control the voting
      power (which includes the power to vote or to direct the voting) of such
      Common Stock. The provisions of this Section (b)(4)(B) shall be effective
      only following (i) the distribution by IMS Health Incorporated ("IMS
      HEALTH") to its stockholders of all of the Class B Common Stock owned by
      it, (ii) the receipt of a private letter ruling from the Internal Revenue
      Service (the "IRS") to the effect that the terms of this Section (b)(4)(B)
      will not have any adverse effect on the private letter ruling issued by
      the IRS to IMS HEALTH on April 14, 1999 and any other private letter
      ruling issued by the IRS to IMS HEALTH or any predecessor or former parent
      of IMS HEALTH and (iii) the approval of the terms of this Section
      (b)(4)(B) by the New York Stock Exchange, Inc. or any other national
      securities exchange or automated quotation service on which the Common
      Stock is then listed or admitted for trading.

                  (C) Any Class A Director may be removed, with or without
      cause, by a vote of a majority of the votes held by the holders of Class A
      Common Stock and holders of Voting Preferred Stock, voting together as a
      class. Any Class B Director may be removed, with or without cause, by a
      vote of a majority of the votes held by the holders of Class B Common
      Stock, voting separately as a class.

                  (D) Except as otherwise specified herein, the holders of Class
      A Common Stock and holders of Class B Common Stock (i) shall in all
      matters not otherwise specified in this Section (b)(4) of this Article IV
      vote together (including, without limitation, with respect to increases or
      decreases in the authorized number of shares of any class of Common
      Stock), with each share of Class A Common Stock and Class B Common Stock
      having one vote, and (ii) shall be entitled to vote as separate classes
      only when required by law to do so under mandatory statutory provisions
      that may not be excluded or overridden by a provision in the Certificate
      of Incorporation or as provided herein.

                  (E) Except as set forth in this Section (b)(4) of this Article
      IV, the holders of Class A Common Stock shall have exclusive voting power
      (except for any voting

                                                                               4

      powers of any Preferred Stock) on all matters at any time when no Class B
      Common Stock is issued and outstanding, and the holders of Class B Common
      Stock shall have exclusive voting power (except for any voting powers of
      any Preferred Stock) on all matters at any time when no Class A Common
      Stock is issued and outstanding.

            (5) Increase or Decreases in Size of the Board of Directors. All
      newly-created directorships resulting from an increase in the authorized
      number of directors shall be allocated between Class A Directors and Class
      B Directors such that at all times the number of directorships reserved
      for Class A Directors shall be 20% of the authorized number of members of
      the Board of Directors (or, if such 20% is not a whole number, then the
      nearest lower whole number of directors that is closest to 20% of such
      membership) and the remaining directorships are reserved for Class B
      Directors. No decrease in the number of directors constituting the Board
      of Directors shall shorten the term of any incumbent director.

            (6) Merger or Consolidation. In case of any consolidation of the
      Corporation with one or more other corporations or a merger of the
      Corporation with another corporation, each holder of a share of Class A
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class B Common Stock, and each holder of a share of Class B
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class A Common Stock; provided that, in any such
      transaction, the holders of shares of Class A Common Stock and the holders
      of shares of Class B Common Stock may receive different kinds of shares of
      stock if the only difference in such shares is the inclusion of voting
      rights which continue the Special Voting Rights.

            (7) Liquidation. In the event of any liquidation, dissolution or
      winding up of the Corporation, the holders of the Class A Common Stock and
      Class B Common Stock shall participate equally per share in any
      distribution to stockholders, without distinction between classes.

                  (c) Preferred Stock. Any Preferred Stock not previously
      designated as to series may be issued from time to time in one or more
      series pursuant to a resolution or resolutions providing for such issue
      duly adopted by the Board of Directors (authority to do so being hereby
      expressly vested in the Board), and such resolution or resolutions shall
      also set forth the voting powers, full or limited or none, of each such
      series of Preferred Stock and shall fix the designations, preferences and
      relative, participating, optional or other special rights and
      qualifications, limitations or restrictions of each such series of
      Preferred Stock; provided that, except for any right to elect directors
      upon the failure of the Corporation to pay regular dividends on such
      Preferred Stock as and when due for a specified period of time, no series
      of Preferred Stock shall be entitled to vote generally in the election of
      any directors of the Corporation other than Class A Directors or to vote
      separately to elect one or more directors of the Corporation. The Board of

      Directors is authorized to alter the designation, rights, preferences,
      privileges and restrictions granted to or imposed upon any wholly unissued
      series of Preferred Stock and, within the limits and restrictions stated
      in any resolution or resolutions of the Board of Directors originally
      fixing the number of shares constituting any series of Preferred Stock, to
      increase or decrease (but not below the number of shares of any such
      series than outstanding) the number of shares of any such subsequent to
      the issue of shares of that series.

                  Each share of Preferred Stock issued by the Corporation, if
      reacquired by the Corporation (whether by redemption, repurchase,
      conversion to Common Stock or other means), shall upon such reacquisition
      resume the status of authorized and unissued shares of Preferred Stock,
      undesignated as to series and available for designation and issuance by
      the Corporation in accordance with the immediately preceding paragraph."

            The Existing Certificate of Incorporation shall be amended by

VIII and IX thereof as Articles V, VI, VII and VIII, respectively.

securing and retaining employees of outstanding ability and to motivate such
employees to exert their best efforts on behalf of the Company and its
Subsidiaries by providing incentives through the granting of Awards. The Company
expects that it will benefit from the added interest which such employees will
have in the welfare of the Company as a result of their proprietary interest in
the Company's success.

                    or consolidation and (B) after which no Person holds 20% or
                    more of the combined voting power of the then-outstanding
                    securities of the Company or such surviving entity;

               (iv) the stockholders of the Company approve a plan of complete
                    liquidation of the Company or an agreement for the sale or
                    disposition by the Company of all or substantially all of
                    the Company's assets; or

               (v)  the Board determines that a Change in Control shall be
                    deemed to have occurred for purposes of the Plan, provided
                    that the Board may impose limitations on the effects of a
                    Change in Control on any Award or otherwise if the Change in
                    Control has occurred under this Section 2(f)(v) and not
                    under other subsections of this Section 2(f).

          (g)  Code: The Internal Revenue Code of 1986, as amended, or any
               successor thereto.

          (h)  Cognizant: Cognizant Corporation, a Delaware corporation.

          (j)  Company: IMS Health Incorporated, a Delaware corporation.

          (k)  Disability: Inability of a Participant to perform the services
               for the Company and its Subsidiaries required by his or her
               employment with the Company due to any medically determinable
               physical and/or mental incapacity or disability which is
               permanent. The determination whether a Participant has suffered a
               Disability shall be made by the Committee based upon such
               evidence as it deems necessary and appropriate. A Participant
               shall not be considered disabled unless he or she furnishes such
               medical or other evidence of the existence of the Disability as
               the Committee, in its sole discretion, may require.

          (l)  Effective Date: The date on which the Plan takes effect, as
               defined pursuant to Section 17 of the Plan.

               exchange on which such Shares are listed or admitted to trading,
               or, if no Composite Tape exists for such national securities
               exchange on such date, then on the principal national securities
               exchange on which such Shares are listed or admitted to trading,
               or, if the Shares are not listed or admitted on a national
               securities exchange, the arithmetic mean of the per Share closing
               bid price and per Share closing asked price on such date as
               quoted on the Nasdaq System (or such market in which such prices
               are regularly quoted), or, if there is no market on which the
               Shares are regularly quoted, the Fair Market Value shall be the
               value established by the Committee in good faith. If no sale of
               Shares shall have been reported on such Composite Tape or such
               national securities exchange on such date or quoted on the Nasdaq
               System on such date, then the immediately preceding date on which

               used.

               notwithstanding, in the case of Awards granted under this Plan
               prior to July 21, 1999, the term "Retirement" shall mean
               termination of employment after the Participant has attained age
               65 or with the prior written consent of the Committee that a
               termination prior to age 65 be treated as a Retirement, except
               that the Committee (or other committee authorized by the Board)
               may determine that the term Retirement as used in respect of
               specified Awards granted prior to July 21, 1999 shall be defined
               as set forth in the first sentence of this definition.

3.   SHARES SUBJECT TO THE PLAN

     (a) Aggregate Share Limitations. Subject to adjustment as provided in
Section 10(a), the total number of Shares which may be issued and/or delivered
under the Plan is 13,000,000 plus the number of Shares reserved for awards under
the IMS Health Incorporated Replacement Plan for Certain Employees Holding
Cognizant Corporation Equity-Based Awards (the "Replacement Plan") that are not
in fact issued or delivered in connection with such awards; provided however,
that in no event may more than 1,000,000 shares be issued as restricted stock or
similar Awards. The Shares may consist, in whole or in part, of authorized and
unissued Shares or treasury Shares. Shares subject to an Award under the Plan
that is canceled, expired, forfeited, settled in cash, or otherwise terminated
without a delivery of Shares to the Participant (or a Beneficiary), including
the number of Shares withheld or surrendered in payment of

                                       4


<PAGE>


any exercise or purchase price of an Award or taxes relating to an Award, will
become available for Awards under the Plan, and Shares shall be counted as
issued or delivered under the Replacement Plan in a manner consistent with the
counting of Shares under this Section 3. In addition, in the case of any Award
granted in substitution for awards of a company or business acquired by the
Company or a Subsidiary, Shares issued or issuable in connection with such
substitute Award shall not be counted against the number of Shares reserved
under the Plan, but shall be deemed to be available under the Plan by virtue of
the Company's assumption of the plan or arrangement of the acquired company or
business.

     (b) Annual Per-Person Limitations. In each calendar year during any part of
which the Plan is in effect, a Participant may be granted Awards under each of
Section 7, Section 8, and Section 9(b) relating to up to the Participant's
Annual Limit (such Annual Limit to apply separately to each Section). A
Participant's Annual Limit, in any year during any part of which the Participant
is then eligible under the Plan, shall equal 1,000,000 shares plus the amount of
the Participant's unused Annual Limit as of the close of the previous year,
subject to adjustment as provided in Section 10(a).

4.   ADMINISTRATION

     (a) The Plan shall be administered by the Committee, which may delegate its
duties and powers in whole or in part to any subcommittee thereof consisting
solely of at least two individuals who are each "non-employee directors" within
the meaning of Rule 16b-3 under the Act (or any successor rule thereto) and
"outside directors" within the meaning of Section 162(m) of the Code (or any
successor section thereto). The Committee is authorized to interpret the Plan,
to establish, amend and rescind any rules and regulations relating to the Plan,
and to make any other determinations that it deems necessary or desirable for
the administration of the Plan. The Committee may correct any defect or supply
any omission or reconcile any inconsistency in the Plan in the manner and to the
extent the Committee deems necessary or desirable. Any decision of the Committee
in the interpretation and administration of the Plan, as described herein, shall
lie within its sole and absolute discretion and shall be final, conclusive and
binding on all parties concerned (including, but not limited to, Participants
and their beneficiaries or successors). The Committee shall require payment of
any amount it may determine to be necessary to withhold for minimum statutory
withholding requirements for federal, state, local or other taxes as a result of
the exercise or settlement of an Award. Unless the Committee specifies
otherwise, the Participant may elect to pay a portion or all of such withholding
taxes by (a) delivery in shares or (b) having shares withheld by the Company
from any shares that would have otherwise been received by the Participant. No
authority to withhold shares is conferred under the Plan to the extent that,
solely due to such authority, an Award would be accounted for as a "variable"
award under APB 25. The Committee may, in its discretion, grant Awards either
alone or in addition to, in tandem with, or in substitution or exchange for, any
other Award or any award granted under another plan of the Company, any
subsidiary, or any business entity to be acquired by the Company or a
subsidiary, or any other right of a Participant to receive payment from the
Company or any subsidiary. If the chief executive officer of the Company is a
member of the Board, the Board by specific resolution may constitute such chief
executive officer as a committee of one which shall have the authority to grant
Awards of up to an aggregate of 50,000 Shares in each calendar year to each
Participant who is not subject to the rules promulgated under Section 16 of the
Act (or any successor section thereto);

                                       5

<PAGE>


provided, however, that such chief executive officer shall notify the Committee
of any such grants made pursuant to this Section 4.

     (b) Without the prior approval of the Company's stockholders, Options
granted under the Plan will not be repriced, replaced or regranted through
cancellation, or by lowering the Option exercise price of a previously granted
Option.

5.   ELIGIBILITY

     Employees (but not members of the Committee or any person who serves only
as a director) of the Company and its Subsidiaries are eligible to be granted
Awards. In addition, any person who has been offered employment by the Company
or a Subsidiary is eligible to be granted Awards, provided that no such person
may receive any payment or exercise any right relating to an Award until such
person has commenced such employment. Participants shall be selected from time
to time by the Committee, in its sole discretion, from among those eligible, and
the Committee shall determine, in its sole discretion, the number of Shares to
be covered by the Awards granted to each Participant.

6.   LIMITATIONS

     No Award may be granted under the Plan after the tenth anniversary of the
Effective Date, but Awards theretofore granted may extend beyond that date.

7.   TERMS AND CONDITIONS OF OPTIONS

     Options granted under the Plan shall be, as determined by the Committee,
non-qualified, incentive or other stock options for federal income tax purposes,
as evidenced by the related Award agreements, and shall be subject to the
foregoing and the following terms and conditions and to such other terms and
conditions, not inconsistent therewith, as the Committee shall determine:

          (a) Option Price. The Option Price per Share shall be determined by
     the Committee, but shall not be less than 100% of the Fair Market Value of
     the Shares on the date an Option is granted. The Committee may require the
     Participant to pay a portion of the Option Price at the time of grant of
     the option, with the remainder of the Option Price payable upon exercise of
     the Option. Such prepayment of the Option Price shall be non-refundable
     except to the extent set forth in a Participant's original option
     agreement.

          (b) Exercisability. Options granted under the Plan shall be
     exercisable at such time and upon such terms and conditions as may be
     determined by the Committee, but in no event shall an Option be exercisable
     more than ten years after the date it is granted.

          (c) Exercise of Options. Except as otherwise provided in the Plan or
     in an Award agreement, an Option may be exercised for all, or from time to
     time any part, of the Shares for which it is then exercisable. For purposes
     of Section 7 of the Plan, the exercise date of an Option shall be the later
     of the date a notice of exercise is received by the Company and, if
     applicable, (A) the date payment is received by the Company pursuant to
     clauses (i), (ii) or (iii) in the following sentence, or (B) the date of
     sale by a broker of all or a portion of the Shares being purchased pursuant
     to clause (iv)

                                       6

<PAGE>


     in the following sentence. Unless otherwise determined by the Committee,
     the Option Price for the Shares as to which an Option is exercised shall be
     paid to the Company in full not later than the time of exercise at the
     election of the Participant (i) in cash, (ii) in Shares having a Fair
     Market Value equal to the aggregate unpaid Option Price for the Shares
     being purchased and satisfying such other requirements as may be imposed by
     the Committee, (iii) partly in cash and partly in such Shares, or (iv)
     through the delivery of irrevocable instructions to a broker to deliver
     promptly to the Company an amount equal to the aggregate Option Price for
     the Shares being purchased. The Award agreement shall, unless otherwise
     provided by the Committee, permit the Participant to elect, subject to such
     terms and conditions as the Committee shall determine, to have the number
     of Shares deliverable to the Participant as a result of the exercise
     reduced by a number sufficient to pay the amount the Company determines to
     be necessary to withhold for federal, state, local or other taxes as a
     result of the exercise of the Option. No Participant shall have any rights
     to dividends or other rights of a stockholder with respect to Shares
     subject to an Option until the Participant has given written notice of
     exercise of the Option, paid in full for such Shares and, if applicable,
     has satisfied any other conditions imposed by the Committee pursuant to the
     Plan.

          (d) Restrictions on Shares Issued Upon Exercise; Other Conditions. If
     and to the extent so determined by the Committee, Shares issued upon
     exercise of an Option may be subject to limitations on transferability,
     risks of forfeiture, deferral of delivery, or such other terms and
     conditions as the Committee may impose, subject to Section 14(b). Such
     terms and conditions may include required forfeiture of Options or gains
     realized upon exercise thereof, for a specified period after exercise, in
     the event the Participant fails to comply with conditions relating to
     non-competition, non-disclosure, non-solicitation or non-interference with
     employees, suppliers, or customers, and non-disparagement and other
     conditions specified by the Committee.

            (e) Exercisability Upon Termination of Employment by Death or
Disability. If a Participant's employment with the Company and its Subsidiaries
terminates by reason by death or Disability after the date of grant of an
Option, (i) the unexercised portion of such Option shall immediately vest in
full (i.e., become non-forfeitable) and (ii) such portion may thereafter be
exercised during the shorter of (A) the remaining stated term of the Option or
(B) five years after the date of death or Disability.

            (f) Exercisability Upon Termination of Employment by Retirement. If
a Participant's employment with the Company and its Subsidiaries terminates by
reason of Retirement after the date of grant of an Option, the Participant's
unexercised Option may thereafter be exercised only during the period ending at
the earlier of five years after such Retirement or the stated expiration date of
such Option (the "Post-Retirement Exercise Period"), provided that such Option
shall be exercisable during such Post-Retirement Exercise Period only to the
extent such Option was exercisable at the time of such Retirement. The foregoing
notwithstanding, (i) the Committee may, in its sole discretion, accelerate the
vesting of the unvested portion of such Option held by a Participant upon such
Participant's Retirement, in which case such Option shall not be forfeited as
provided herein but thereafter shall become exercisable to the extent and at
such times as such portion of the Option would have become both vested and
exercisable during the Post-Retirement Exercise Period had the Participant's
employment not been terminated, unless the Committee specifies otherwise; and
(ii), if a Participant dies within a period of five years after such Retirement,
the Participant's unexercised Option (to the extent not previously forfeited)
may thereafter be exercised during the shorter of (i) the remaining stated term
of the Option or (ii) the period that is

                                       7

<PAGE>


the longer of (A) five years after the date of such termination of employment or
(B) one year after the date of death.

     (g) Effect of Other Termination of Employment. If a Participant's
employment with the Company and its Subsidiaries terminates for any reason other
than death, Disability or Retirement after the date of grant of an Option as
described above, the Participant's unexercised Option may thereafter be
exercised during the period ending 90 days after the date of such termination of
employment, but only to the extent such Option was exercisable at the time of
such termination of employment, and in no event may such Option be exercised
after its stated expiration date. The foregoing notwithstanding, the Committee
may, in its sole discretion, accelerate the vesting of unvested Options held by
a Participant if such Participant is terminated from employment without "cause"
(as such term is defined by the Committee in its sole discretion) by the
Company.

8.   TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS

     (a) Grants. The Committee also may grant (i) a Stock Appreciation Right
independent of an Option or (ii) a Stock Appreciation Right in connection with
an Option, or a portion thereof. A Stock Appreciation Right granted pursuant to
clause (ii) of the preceding sentence (A) may be granted at the time the related
Option is granted or at any time prior to the exercise or cancellation of the
related Option, (B) shall cover the same Shares covered by an Option (or such
lesser number of Shares as the Committee may determine) and (C) shall be subject
to the same terms and conditions as such Option except for such additional
limitations as are contemplated by this Section 8 (or such additional
limitations as may be included in an Award agreement).

     (b) Terms. The exercise price per Share of a Stock Appreciation Right shall
be an amount determined by the Committee but in no event shall such amount be
less than the greater of (i) the Fair Market Value of a Share on the date the
Stock Appreciation Right is granted or, in the case of a Stock Appreciation
Right granted in conjunction with an Option, or a portion thereof, the Option
Price of the related Option and (ii) an amount permitted by applicable laws,
rules, by-laws or policies of regulatory authorities or stock exchanges. Each
Stock Appreciation Right granted independent of an Option shall entitle a
Participant upon exercise to an amount equal to (i) the excess of (A) the Fair
Market Value on the exercise date of one Share over (B) the exercise price per
Share, times (ii) the number of Shares covered by the Stock Appreciation Right.
Each Stock Appreciation Right granted in conjunction with an Option, or a
portion thereof, shall entitle a Participant to surrender to the Company the
unexercised Option, or any portion thereof, and to receive from the Company in
exchange therefor an amount equal to (i) the excess of (A) the Fair Market Value
on the exercise date of one Share over (B) the Option Price per Share, times
(ii) the number of Shares covered by the Option, or portion thereof, which is
surrendered. The date a notice of exercise is received by the Company shall be
the exercise date. Payment shall be made in Shares or in cash, or partly in
Shares and partly in cash, valued at such Fair Market Value, all as shall be
determined by the Committee. Stock Appreciation Rights may be exercised from
time to time upon actual receipt by the Company of written notice of exercise
stating the number of Shares subject to an exercisable Option with respect to
which the Stock Appreciation Right is being exercised. No fractional Shares will
be issued in payment for Stock Appreciation Rights, but instead cash will be
paid for a fraction or, if the Committee should so determine, the number of
Shares will be rounded downward to the next whole Share.

                                       8


<PAGE>


     (c) Limitations. The Committee may impose, in its discretion, such
conditions upon the exercisability or transferability of Stock Appreciation
Rights as it may deem fit.

     (d) Limited Stock Appreciation Rights. The Committee may grant LSARs that
are exercisable upon the occurrence of specified contingent events. Such LSARs
may provide for a different method of determining appreciation, may specify that
payment will be made only in cash and may provide that any related Awards are
not exercisable while such LSARs are exercisable. Unless the context otherwise
requires, whenever the term "Stock Appreciation Right" is used in the Plan, such
term shall include LSARs.

9.   OTHER STOCK-BASED AWARDS

     (a) Generally. The Committee, in its sole discretion, may grant Awards of
Shares, Awards of restricted Shares and Awards that are valued in whole or in
part by reference to, or are otherwise based on the Fair Market Value of, Shares
("Other Stock-Based Awards"). Such Other Stock-Based Awards shall be in such
form, and dependent on such conditions, as the Committee shall determine,
including, without limitation, the right to receive one or more Shares (or the
equivalent cash value of such Shares) as an outright bonus or upon the
completion of a specified period of service, the occurrence of an event and/or
the attainment of performance objectives. Other Stock-Based Awards may be
granted alone or in addition to any other Awards granted under the Plan. Subject
to the provisions of the Plan, the Committee shall determine to whom and when
Other Stock-Based Awards will be made, the number of Shares to be awarded under
(or otherwise related to) such Other Stock-Based Awards; whether such Other
Stock-Based Awards shall be settled in cash, Shares or a combination of cash and
Shares; and all other terms and conditions of such Awards (including, without
limitation, the vesting provisions thereof). Cash awards, as an element of or
supplement to any other Award under the Plan, may also be granted pursuant to
this Section 9(a). In addition, the Committee is authorized to grant dividend
equivalents to a Participant, entitling the Participant to receive cash, Shares,
other Awards, or other property equal in value to dividends paid with respect to
a specified number of Shares, or other periodic payments. Dividend equivalents
may be awarded on a free-standing basis or in connection with another Award. The
Committee may provide that Dividend Equivalents shall be paid or distributed
when accrued or shall be deemed to have been reinvested in additional Shares,
Awards, or other investment vehicles, subject to such restrictions on
transferability and risks of forfeiture as the Committee may specify.

     (b) Performance-Based Awards. Notwithstanding anything to the contrary
herein, certain Other Stock-Based Awards granted under this Section 9 may be
granted in a manner which is deductible by the Company without limitation under
Section 162(m) of the Code (or any successor section thereto)
("Performance-Based Awards"). A Participant's Performance-Based Award shall be
determined based on the attainment of written performance goals approved by the
Committee for a performance period established by the Committee (i) while the
outcome for that performance period is substantially uncertain and (ii) no more
than 90 days after the commencement of the performance period to which the
performance goal relates or, if less, the number of days which is equal to 25
percent of the relevant performance period. The performance goals, which must be
objective, shall be based upon one or more of the following criteria: (i)
consolidated earnings before or after taxes (including earnings before


                                       9

<PAGE>


interest, taxes, depreciation and amortization); (ii) net income; (iii)
operating income; (iv) earnings per share; (v) book value per share; (vi) return
on stockholders' equity; (vii) expense management; (viii) return on investment;
(ix) improvements in capital structure; (x) profitability of an identifiable
business unit or product; (xi) maintenance or improvement of profit margins;
(xii) stock price; (xiii) market share; (xiv) revenues or sales; (xv) costs;
(xvi) cash flow; (xvii) working capital; (xviii) economic value added; (xix)
return on assets; (xx) total stockholder return (stock price appreciation plus
dividends and distributions); (xxi) operating management goals; (xxii) and
execution of pre-approved corporate strategy. The foregoing criteria may relate
to the Company, one or more of its Subsidiaries or one or more of its divisions
or units, or any combination of the foregoing, and may be applied on an absolute
basis and/or be relative to one or more peer group companies or indices, or any
combination thereof, all as the Committee shall determine. In addition, to the
degree consistent with Section 162(m) of the Code (or any successor section
thereto), the performance goals may be calculated without regard to
extraordinary items. In the case of a Performance-Based Award which is not
valued in a way in which the limitation set forth in the final sentence of
Section 3 would operate as an effective limitation satisfying Treasury
Regulation 1.162-27(e)(4), the maximum amount of a Performance-Based Award to
any Participant with respect to performance in a single fiscal year of the
Company shall be $5,000,000. The Committee shall determine whether, with respect
to a performance period, the applicable performance goals have been met with
respect to a given Participant and, if they have, to so certify and ascertain
the amount of the applicable Performance-Based Award. No Performance-Based
Awards will be paid for such performance period until such certification is made
by the Committee. The amount of the Performance-Based Award actually paid to a
given Participant may be less than the amount determined by the applicable
performance goal formula, at the discretion of the Committee. The amount of the
Performance-Based Award determined by the Committee for a performance period
shall be paid to the Participant at such time as determined by the Committee in
its sole discretion after the end of such performance period; provided, however,
that a Participant may, if and to the extent permitted by the Committee and
consistent with the provisions of Section 162(m) of the Code, elect to defer
payment of a Performance-Based Award.

10.  ADJUSTMENTS UPON CERTAIN EVENTS

     Notwithstanding any other provisions in the Plan to the contrary, the
following provisions shall apply to all Awards granted under the Plan:

     (a) Generally. In the event of any change in the outstanding Shares after
the Effective Date by reason of any Share dividend or split, reorganization,
recapitalization, merger, consolidation, spin-off, combination or exchange of
Shares of other corporate exchange, or any large, special, and non-recurring
distribution to Stockholders, the Committee in its sole discretion and without
liability to any person may make such substitution or adjustment, if any, as it
deems to be equitable, as to (i) the number or kind of Shares or other
securities issued or reserved for issuance pursuant to the Plan or pursuant to
outstanding Awards, (ii) the Option Price, (iii) the number and kind of Shares
by which annual per-person Award limitations are measured under Section 3 hereof
and/or (iv) any other affected terms of such Awards (including making provision
for the payment of cash, other Awards or other property in respect of any
outstanding Award). In addition, the Committee is authorized to make adjustments
in the terms and conditions of, and the criteria included in, Awards in
recognition of unusual or nonrecurring events (including, without limitation,
events described in the

                                       10

preceding sentence, as well as acquisitions and dispositions of businesses and
assets) affecting the Company, any subsidiary or any business unit, or the
financial statements of the Company or any subsidiary, or in response to changes
in applicable laws, regulations, accounting principles, tax rates and
regulations or business conditions or in view of the Committee's assessment of
the business strategy of the Company, any subsidiary or business unit thereof,
performance of comparable organizations, economic and business conditions,
personal performance of a Participant, and any other circumstances deemed
relevant; provided that no such adjustment shall be authorized to be made if and
to the extent that such authority or the making of such adjustment would cause
Options, Stock Appreciation Rights, or Performance Awards granted under Section
9(b) hereof intended to qualify as "performance-based compensation" under Code
Section 162(m) and regulations thereunder to otherwise fail to so qualify.

     (b) Change in Control. Except as otherwise provided in an Award agreement,
in the event of a Change in Control, the Committee in its sole discretion and
without liability to any person may take such actions, if any, as it deems
necessary or desirable with respect to any Award (including, without limitation,
(i) the acceleration of an Award, (ii) the payment of a cash amount in exchange
for the cancellation of an Award and/or (iii) the requiring of the issuance of
substitute Awards that will substantially preserve the value, rights and
benefits of any affected Awards previously granted hereunder) as of the date of
the consummation of the Change in Control.

11.  NO RIGHT TO EMPLOYMENT

     The granting of an Award under the Plan shall impose no obligation on the
Company or any Subsidiary to continue the employment of a Participant and shall
not lessen or affect the Company's or Subsidiary's right to terminate the
employment of such Participant.

12.  SUCCESSORS AND ASSIGNS

     The Plan shall be binding on all successors and assigns of the Company and
a Participant, including without limitation, the estate of such Participant and
the executor, administrator or trustee of such estate, or any receiver or
trustee in bankruptcy or representative of the Participant's creditors.

13.  NONTRANSFERABILITY OF AWARDS

     An Award shall not be transferable or assignable by the Participant
otherwise than by will or by the laws of descent and distribution. During the
lifetime of a Participant, an Award shall be exercisable only by such
Participant. An Award exercisable after the death of a Participant may be
exercised by the legatees, personal representatives or distributees of the
Participant. Notwithstanding anything to the contrary herein, the Committee, in
its sole discretion, shall have the authority to waive this Section 13 (or any
part thereof) to the extent that this Section 13 (or any part thereof) is not
required under the rules promulgated under any law, rule or regulation
applicable to the Company.

14.  AMENDMENTS OR TERMINATION

     (a) Changes to the Plan. The Board may amend, alter or discontinue the
Plan, except that (i) any amendment or alteration shall be subject to the
approval of

                                       11

<PAGE>


the Company's stockholders at or before the next annual meeting of stockholders
for which the record date is after the date of such Board action if (x) such
stockholder approval is required by any federal or state law or regulation or
the rules of any stock exchange or automated quotation system on which the
Shares may then be listed or quoted, and the Board may otherwise, in its
discretion, determine to submit amendments or alterations to stockholders for
approval or (y) such amendment or alteration would materially increase the
number of shares reserved for the purposes of the Plan, materially broaden the
employees or class of employees eligible to receive Awards under the Plan or
materially increase benefits accruing to employees participating in the Plan;
(ii) without the consent of a Participant, no amendment or alteration shall
materially impair any of the Participant's rights under an Award theretofore
granted to such Participant; and (iii) the Committee may amend or alter the Plan
in such manner as it deems necessary to permit the granting of Awards meeting
requirements of the Code or other applicable laws. Notwithstanding anything to
the contrary herein, the Board may not amend, alter or discontinue the
provisions relating to Section 10(b) of the Plan after the occurrence of a
Change in Control.

     (b) Changes to Outstanding Awards. The Committee may waive any conditions
or rights under, or amend, alter, suspend, discontinue, or terminate any Award
theretofore granted and any Award agreement relating thereto, except as
otherwise provided in the Plan and except that the Committee may not amend or
alter an Award theretofore granted if such action would result in an Award
having terms that would not have been authorized or permitted for a new grant or
Award under the Plan; provided that, without the consent of an affected
Participant, no such Committee action may materially and adversely affect the
rights of such Participant under such Award. Other provisions of the Plan
notwithstanding, if any right under this Plan would cause a transaction to be
ineligible for pooling of interest accounting that would, but for the right
hereunder, be eligible for such accounting treatment, the Committee may modify
or adjust the right so that pooling of interest accounting shall be available,
including the substitution of Shares having a Fair Market Value equal to the
cash otherwise payable hereunder for the right which caused the transaction to
be ineligible for pooling of interest accounting.

15.  INTERNATIONAL PARTICIPANTS

     With respect to Participants who reside or work outside the United States
of America and either who are not (and who are not expected to be) "covered
employees" within the meaning of Section 162(m) of the Code or who are granted
Awards not intended to qualify as "performance-based compensation" under Section
162(m), the Committee may, in its sole discretion, amend the terms of the Plan
or Awards with respect to such Participants in order to conform such terms with
local laws, regulations, or customs or otherwise to meet the objectives of the
Plan, and may, where appropriate, establish one or more sub-plans to reflect
such amended provisions.

16.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of the Plan by the Board nor any submission of the
Plan, specific Plan terms, or amendments thereto to a vote of stockholders of
the Company shall be construed as creating any limitations on the power of the
Board to adopt such other compensatory arrangements as it may deem desirable,
including, without limitation, the granting of awards otherwise than under the
Plan, and such other arrangements may be either applicable generally or only in
specific cases.

                                       12

17.  CHOICE OF LAW

     The Plan shall be governed by and construed in accordance with the laws of
the State of New York.

18.  EFFECTIVENESS OF THE PLAN

     The Plan shall be effective as of the Spinoff Date.
