      As used in this report, except where the context indicates otherwise, the
terms "Company" and "IMS HEALTH" mean IMS Health Incorporated and all
subsidiaries consolidated in the financial statements contained or incorporated
by reference herein.

ITEM 1. BUSINESS

     IMS Health Incorporated ("accounting successor to Cognizant") was
incorporated under the laws of the State of Delaware on February 3, 1998. The
Company began operating as an independent publicly held company on July 1, 1998
(the "Distribution Date") as a result of its spin-off (the "Cognizant Spin-off")
from Cognizant Corporation ("Cognizant"). Prior to the Cognizant Spin-off, the
Company was owned by Cognizant. Cognizant began operating as an independent
publicly held company on November 1, 1996 as a result of its spin-off (the "D&B
Spin-off") from The Dun & Bradstreet Corporation ("Dun & Bradstreet"). Prior to
the D&B Spin-off, Cognizant was owned by Dun & Bradstreet.

     The Common stock of IMS HEALTH was distributed by Cognizant Corporation
("Cognizant") to its shareholders on June 30, 1998. Simultaneously with the
distribution Cognizant changed its name to Nielsen Media Research, Inc.
("Nielsen Media Research"). Notwithstanding the legal form of the distribution,
whereby Cognizant spun off IMS HEALTH, for accounting purposes the transaction
is accounted for as if Cognizant spun off Nielsen Media Research and IMS HEALTH
has been deemed the "accounting successor" to Cognizant. The separation created
IMS HEALTH as the premier global provider of information solutions to the
pharmaceutical and healthcare industries, and established an independent Nielsen
Media Research, the leader in North American electronic audience measurement
services.

      On November 11, 1998 the Company announced that its Board of Directors
approved a plan, in principle, to spin-off substantially all of its equity
ownership of Gartner Group, Inc. ("Gartner"). The transaction, expected to be
completed in the first half of 1999, is to be structured as a tax-free
distribution of Gartner stock to IMS HEALTH shareholders.

     At the December 31, 1998 the Company owned approximately 47 million shares
of Gartner. Prior to the spin-off, 40.1 million of these shares will be
exchanged for new Class B Common Stock of Gartner. The Class B Stock will be
entitled to elect 80% of Gartner's Board of Directors, but will otherwise be
identical to existing Class A Common Stock. The exchange will be part of a
Gartner recapitalization. The Class B shares will be distributed to the
Company's shareholders in a tax-free distribution, subject to receipt of a
favorable tax ruling from the Internal Revenue Service ("IRS") with respect to
the distribution. The Company intends to monetize its remaining position in
Gartner by the end of 1999. This includes 6.9 million shares of Class A Common
Stock and warrants to purchase a further 600,000 shares.

     Separately, Gartner announced that, subject to approval by the IRS of the
tax-free treatment of the distribution, it intends to declare a special one-time
cash dividend of $300 million to its shareholders of record immediately prior to
the spin-off. The Gartner Board of Directors also announced that it intends to
authorize a $300 million open market share repurchase program for up to 20% of
its stock commencing immediately after the spin-off.

     The transaction is subject to receipt of a favorable ruling from the IRS,
final approval by the Company's and Gartner Boards of Directors, and approval by
Gartner shareholders.

     IMS HEALTH is the global provider of information solutions to the
pharmaceutical and healthcare industries. 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"),
IMS Health Strategic Technologies Inc. ("Strategic Technologies"), which is a
leading provider of automated sales support to the pharmaceutical industry,
ERISCO Managed Care Technologies, Inc. ("Erisco"), which provides application
software and services to the healthcare industry to help manage the
administration of group health and life insurance products, Enterprise
Associates, Inc. ("Enterprises"), which invests in businesses mainly in the
information technology and healthcare information industries, a 61.7% ownership
interest in Cognizant Technology Solutions Corporation ("CTS"), which provides
software solutions to complex IT problems including application development and
maintenance services and Year 2000 and Eurocurrency compliance services. The
Company also has an equity investment in Gartner Group, Inc. ("Gartner"), the
premier provider of research and advisory services to the information technology
industry. The Company operates in approximately 90 countries. The number of
full-time equivalent employees at December 31, 1998 was approximately 8,000.

     The Company's operations can be grouped into the following business
segments: IMS, Emerging Markets, and CTS, plus its equity investment in Gartner.
Gartner is the leading independent provider of research and analysis on the
computer hardware, software, communications and related technology industries.

                                       IMS

      The IMS segment provides information and decision-support services to the
pharmaceutical and healthcare industries worldwide. These services broadly
include market research services, sales management services, sales force
automation and other professional, software, direct marketing and research and
development services. IMS provides information services covering 94 countries
and maintains offices in 74 countries on six continents, with 62% of total
revenue generated outside the United States in 1998. In 1998, IMS continued its
expansion in developing markets in Eastern Europe and Sub-Saharan Africa.
Revenue in 1998 increased by 22% compared with 1997 in these developing markets.

      Sales management services represented approximately 48% of the IMS
segment's worldwide revenue in 1998. Sales management services include sales
territory reports, prescription tracking reports and doctor profiling services.
These reports are customized for each pharmaceutical client and are used
principally by pharmaceutical manufacturers to measure and forecast the
effectiveness and efficiency of sales representatives and to target the
marketing and sales efforts of a client's salesforce. IMS's principal sales
management services are as follows:

      o     Sales Territory Reporting Services. Sales territory reporting is the
            principal sales management service offered by IMS to its
            pharmaceutical clients. Sales territory reports can be precisely
            tailored for each client, and measure the sales of a client's own
            products and those of competitors within specified geographical
            configurations. These reports are designed to provide marketing and
            sales managers with a reliable measurement of each salesperson's
            activity and effectiveness in his or her sales territory, and
            therefore are used by clients, among other things, for determining
            sales force compensation. Data reported for multiple territories are
            used for applications such as resource allocation, territory
            alignment, market analyses and distribution management. Depending on
            the particular market, sales territory reports are available to
            clients on a weekly, monthly or quarterly basis. In the United
            States, sales territory reports from IMS's DDD service allow
            pharmaceutical clients to track the flow of their products and those
            of their competitors to various levels of geography and channels of
            distribution. The DDD database contains a virtual census of sales of
            pharmaceutical products through all distribution channels, including
            direct sales by pharmaceutical manufacturers and indirect sales
            through drug wholesalers, mail order distributors, warehousing
            chains and other market participants. IMS provides sales territory
            reporting services in 35 countries.

      o     Prescription Tracking Reporting Services. Prescription tracking
            reporting services are designed to monitor prescription activity and
            to track the movement of pharmaceutical products out of pharmacies.
            Prescription tracking services are used by pharmaceutical companies
            to facilitate product marketing at the prescriber level. In the
            United States, the Xponent service monitors prescription activity at
            the retail pharmacy and mail order outlet level, and uses a patented
            statistical methodology to project the prescription activity of
            nearly one million individual prescribers on a monthly basis.
            Xponent is currently under development in Europe. The Europe Xponent
            database is built from prescription data collected from retail
            pharmacies and coding centers which are linked to the geographical
            area in which the prescription was written, and where permissible
            under local data privacy laws, to individual prescribers. Europe
            Xponent is in development in the United Kingdom, Germany, Belgium,
            the Netherlands, Italy, France and Spain. The acquisition of PMSI
            has accelerated the development of Xponent.

            Sales management reporting services are made available to clients
and their sales representatives and management via hardcopy reports, CD-ROMs,
software application tools, computer on-line services, web based access and
magnetic media for use in client computer systems and IMS's customized
electronic workstations. IMS's data delivery systems assist clients in
maximizing efficiency by aiding in the setting of sales targets and calculation
of sales commissions; giving fast access to sales data and permitting more
sophisticated analyses; improving call reporting; and improving communication
between sales management and their sales forces. In the United States, IMS has
several customized client-server decision support systems that allow a client to
store large amounts of data at its own site and integrate its own internal sales
and marketing data with IMS data and other external data. IMS also provides
clients with customized data warehouse tools and web based access capabilities.

            Market research services represented approximately 35% of the IMS
segment's worldwide revenue in 1998. The principal market research services are
syndicated pharmaceutical, medical, hospital, promotional, prescription and
self-medication audits. Market research services are utilized by clients for
various strategic purposes, including analyzing market shares, therapeutic
prescribing trends and price movements at the national and subnational levels.
The information reported in these services is generated or derived from data
collected primarily from pharmaceutical manufacturers, pharmaceutical
wholesalers, pharmacies, hospitals and doctors. Market research services are
delivered to clients via hardcopy reports, CD-ROMs, software application tools,
computer on-line services, and magnetic media for use in client computer systems
and IMS's customized electronic workstations. IMS's principal market research
services are as follows:


                                       3

      o     Pharmaceutical Audits. These audits measure the sale of
            pharmaceutical products into pharmacies, supplemented in some
            countries by data collected from prescribing physicians, retail
            chains and discount stores. These audits contain data projected to
            national estimates, showing product sales by therapeutic class
            broken down by package size and dosage form. IMS publishes
            pharmaceutical audits in over 83 countries.

      o     Medical Audits. These audits are based on information collected from
            panels of practicing physicians and contain projected national
            estimates of the number of consultations for each diagnosed disease
            with details of the therapy prescribed. These audits also analyze
            the use physicians make of individual drugs by listing the diseases
            for which they are prescribed, the potential therapeutic action the
            physician is expecting, other drugs prescribed at the same time, and
            estimates of the total number of drugs used for each disease. IMS
            publishes medical audits in over 47 countries.

      o     Hospital Audits. These audits contain data projected to national
            estimates and show the sale of pharmaceutical products to hospitals
            by therapeutic class. Related reports provide audits of laboratory
            diagnostic supplies, hospital supplies, and hospital records. IMS
            publishes hospital audits for 38 countries.

      o     Promotional Audits. These audits measure pharmaceutical promotion
            for a particular market, including sales-force promotion and journal
            and mail advertising, based on information received from panels of
            physicians and from monitoring medical journals and direct mail. IMS
            publishes promotional reports for 26 countries.

      o     Prescription Audits. These audits analyze the rate at which drugs
            move out of the pharmacy and into the hands of the consumer, and
            measure both what is prescribed by physicians and what is actually
            dispensed at the pharmacy. IMS publishes prescription audits in over
            15 countries.

      o     Self-Medication and OTC Reports. These reports provide detailed
            product movement, market share and pricing information for
            over-the-counter, personal care and patient care products. IMS
            publishes self-medication reports in 34 countries.

      o     Other Market Research Reports. These include managed care reports
            which offer an array of information to quantify the effects of
            managed care on the pharmaceutical and healthcare industry; personal
            care reports which measure the sale of healthcare accessories, wound
            care and dietetic aids; and veterinary reports which analyze the
            animal care pharmaceutical market. IMS has developed, in certain
            countries, disease and treatment information at the patient level
            (which information is not identifiable to any individual patient)
            that gives participants in the healthcare industry new insights into
            the treatment of diseases. The availability, scope and frequency of
            the foregoing reports vary on a country-by-country basis.

     The remaining 17% of the IMS segment's 1998 revenue was derived primarily
through professional consulting, software, direct marketing, research and
development services, and sales support technology. IMS provides pharmaceutical
and other clients with a range of value-added services that are used (i) to
study specific issues and trends in the pharmaceutical marketplace and the
healthcare industry, (ii) to manage sales and marketing, (iii) to evaluate the
effectiveness of marketing programs, (iv) to analyze components of a product
marketing program at any stage of its implementation, and (v) for consultancy
in optimizing strategy, marketing programs and product commercialization. These
services are as follows:

      o     IMS Global Services. IMS's Global Services unit is based in the
            United Kingdom and the United States and provides access to global
            level information services to pharmaceutical clients operating on a
            multinational level. Global Services' core service offering,
            MIDAS(TM), is an on-line multinational integrated data analysis tool
            which harnesses IMS's worldwiDE databases and is used by the
            pharmaceutical industry to assess and utilize pharmaceutical
            information and trends in multiple markets. MIDAS gives clients
            on-line access to IMS-compiled pharmaceutical, medical, promotional

            pharmaceutical marketplace and provides custom market research and
            strategic consultancy.

      o     Territory enterprise relationship management systems. Strategic
            Technologies, a subsidiary of IMS HEALTH is a leading provider of
            automated sales support technologies to the pharmaceutical industry.

            Technologies' solutions to make critical sales and marketing
            decisions on a daily basis. Three industry-leading IMS HEALTH

            re-programming. Sales and marketing professionals at every level of
            an organization can use Premiere to develop selling strategies,
            allocate and coordinate sales resources, track competitive activity,
            and plan, monitor and evaluate sales activity. Precise(SM)2000 is an

            increase productivity, to target prospective customers and to
            improve decision-making within a sales organization. Management is
            currently developing a next stage integrated and global sales
            management information system. Strategic Technologies is a market
            leader in application of a variety of hand held devices which offer
            greater portability in developed markets and a low cost entry
            strategy into sales force automation in emerging markets.

      o     Professional Consulting Services. IMS's professional consulting
            services are provided to assist clients in the analysis and
            evaluation of market trends, strategies and tactics, and to assist
            in the development and implementation of customized software
            applications and data warehouse tools. In the United States, IMS's
            professional consulting services provides a wide range of custom

            consulting group also assists clients in designing customized
            decision support systems based on a variety of cutting-edge
            technologies which enable clients to optimize IMS data more rapidly
            and effectively in their decision-making process. Outside of the
            United States, a variety of consulting services is generally offered
            on a country-by-country basis.

      o     Direct Marketing Services. IMS engages in the direct marketing
            businesses in the United States. Clark-O'Neill, Inc.
            ("Clark-O'Neill"), a wholly-owned subsidiary, represents the core of
            IMS's direct marketing business. Clark-O'Neill's services include
            sample distribution, pharmaceutical field salesforce support
            services, publication circulation management, direct mail,
            telemarketing projects utilizing physicians and other healthcare
            professionals, and other customized promotion programs.

      o     Research and Development Services. IMS's research and development
            services provide clients with information and workstation tools
            intended to improve the effectiveness and speed of clinical research
            and subsequent regulatory approvals. IMS's regulatory affairs
            database, IDRAC, covers the European Union, certain Eastern European
            countries, Japan and the United States, guides users through the
            drug development and registration process. IMS also owns a 40%
            equity interest in DataEdge, an information provider to the
            pharmaceutical industry on clinical trial design and implementation.

      o     Pharmacy dispensing and point-of-sales software systems. IMS also
            provides pharmacy dispensing and point-of-sale software systems to
            retail pharmacies in the United Kingdom and Australia.

      Over the past four decades, IMS has developed strong relationships with
its data suppliers in each market in which it operates. As the supply of
pharmaceutical data is critical to IMS's business, IMS devotes significant human
and financial resources to its data collection efforts and in many cases has
historical connections with the trade associations and professional associations
involved. In the United States, IMS HEALTH and Clark-O'Neill each have been
designated as database licensees by the American Medical Association ("AMA") for
use and sublicensing of the AMA's physician database.

      Sales to the healthcare industry accounted for substantially all of the
IMS segment's revenue in 1998. All major pharmaceutical companies are customers
of IMS, and many of the companies subscribe to reports and services in several


                                       5
<PAGE>

countries. IMS's customer base is broad in scope and enables it to avoid
dependence on any single customer. None of IMS's customers accounted for more
than 10% of the Company's gross revenues in 1998.

      While no competitor provides the geographical reach or breadth of IMS's
services, IMS generally has competition in the countries in which it operates
from other information services companies, as well as the in-house capabilities
of its customers. Generally, competition has arisen on a country-by-country
basis. In the United States, certain of IMS's sales management services,
including its sales territory and prescription tracking reports, representing
approximately 60% of the annual revenue of the US unit, compete with the
services of National Data Corp. Quality, completeness and speed of delivery of
information services and products are the principal methods of competition in
IMS's market.

                                EMERGING MARKETS

This segment is comprised of Erisco, Enterprises and SSJ K.K. ("SSJ").

ERISCO

      Erisco has been a leading provider of application software and services to
the healthcare industry for over two decades. Erisco's legacy system solutions,
ClaimFacts and GroupFacts, were designed to help indemnity insurance carriers,
third party administrators and self-administered corporations manage the
administration of group health and life insurance products.

      Erisco's primary offering, Facets, is a client/server system which
integrates advanced technology with clinical information to help managed care
organizations ("MCOs") provide high-quality, cost-effective solutions in their
marketplace. Primary markets include health maintenance organizations, preferred
provider organizations, Blue Cross/Blue Shield organizations, managed-indemnity
carriers and specialized MCOs.

      Erisco's strategic growth will come from Facets sales to the MCO market.
Ongoing change in healthcare has had a significant impact on this market
segment, resulting in the migration of plan members from indemnity-oriented
plans to managed care. By the year 2000, managed health plan membership in the
United States is estimated to surpass the 100 million mark. This significant
market growth combined with the limitations of aging information systems, will
continue to increase the demand for sophisticated managed care applications.

      Erisco also extends its Facets business solution through a service bureau
offering for low-volume customers, and through alliances with strategic,
complementary systems partners, and systems integration and implementation
consultants.

      Within the high-growth managed care market segment, Erisco competes with
three other information systems vendors; McKessonHBOC, Computer Sciences
Corporation and Health Systems Design. Competition is principally based on
company reputation, system functionality and technology, and ease of use and
service.

ENTERPRISES

      Enterprises invests in emerging and established businesses, with an
emphasis on information technology and the health care information industry. It
has invested as a limited partner in Information Partners Capital Fund,
Information Associates, L.P. and Information Associates II, L.P., all of which
are venture capital limited partnerships, as well as through direct investments.

SSJ

      SSJ is based in Japan and markets financial application software products
and services tailored for the Japanese market.

                                       CTS

       In the second quarter of 1998, CTS effected an initial public offering of
its Class A Common Stock. As of December 31, 1998 IMS HEALTH owns 61.7% of the
outstanding common stock of CTS, representing approximately 94% of the combined
voting power of CTS' common stock. CTS is quoted on the Nasdaq National Market
under the trading symbol "CTSH." CTS provides various software development and
maintenance services to IMS Health and is subsidiaries, including assisting in
IMS HEALTH'S Year 2000 compliance efforts. IMS HEALTH provides certain
administrative services to CTS pursuant to an agreement entered into in
connection with the public offering.

       During 1998, CTS recorded intercompany sales of approximately $13
million, principally to the IMS segment. These sales are eliminated in
consolidation.

      CTS delivers high-quality, cost-effective, full life cycle solutions to
complex software development and maintenance problems. Its services include the
following:

      o     Application Development Services. CTS develops new applications for
            IBM mainframe, client/server architectures and other emerging
            technology environments. CTS follows either of two approaches,
            including (i) full life cycle application development in which CTS
            assumes total start-to-finish responsibility and accountability for
            analysis, design, implementation and testing of systems, or (ii)
            cooperative development in which CTS's employees work with a
            customer's in-house information technology ("IT") personnel to
            analyze, design, implement and test new systems.

      o     Application Maintenance Support Services. CTS provides services to
            ensure that a customer's legacy software systems are operational and
            responsive to end-users' changing needs. In doing so, CTS is often
            able to introduce process enhancements and improve service levels to
            customers requesting modifications and on-going support.

      o     Year 2000 Compliance Services. With the year 2000 approaching,
            computer software systems that were not designed to process dates
            correctly in the next century are expected to fail. Organizations
            rely on mission-critical software systems and must either repair the
            problem presented by the Year 2000 issue or replace legacy systems.
            CTS uses its proprietary Year 2000 toolset and methodology, Century
            Transition Services 2000, to provide a cost-effective total solution
            for all phases of a Year 2000 compliance project. The Century
            Transition Services 2000 methodology covers the entire life cycle of
            a Year 2000 compliance project and comprises a seven step process:
            (i) inventory preparation, (ii) impact analysis, (iii) strategy and
            design, (iv) code change and data migration, (v) unit, system and
            acceptance testing, (vi) implementation and (vii)
            post-implementation support. The Century Transition Services 2000
            toolset covers a wide array of common programming languages and
            environments including many client/server environments. CTS is thus
            able to provide complete solutions across a large portion of
            customers' systems.

      o     Eurocurrency Compliance Services. The monetary union of the European
            Community presents a significant opportunity for CTS as computer
            systems which deal with any European denominated currency modified
            to handle local currency and Eurocurrency transactions. CTS is
            addressing the Eurocurrency compliance problem and has established a
            dedicated practice to focus on this problem. CTS believes that
            portions of its Year 2000 toolset and methodology can be extended to
            efficiently address the European currency compliance needs of
            customers.

      o     Testing and Quality Assurance Services. Testing and quality
            assurance is a critical aspect of any software development activity.
            CTS works with customers to better define the quality assurance
            processes which are in use by the customers' in-house IT
            departments. CTS utilizes its quality assurance expertise to ensure
            better quality software through fundamental process improvements.

      o     Re-Hosting and Re-Engineering Services. Through CTS's re-hosting and
            re-engineering service offerings, CTS works with customers to
            migrate systems based on legacy computing environments to newer,
            open-systems-based platforms and client/server architectures.

      The IT services market includes a large number of participants, is subject
to rapid changes and is highly competitive. Many of CTS's competitors have
significantly greater financial, technical and marketing resources and greater
name recognition than CTS. The principal competitive factors affecting the
markets for CTS's services include (i) performance and reliability, (ii) quality
of technical support, training and services, (iii) responsiveness to customer
needs, (iv) reputation, experience and financial stability and (v) competitive
pricing of services.

                                 RESOURCE GROUP

      Shared Business Services began operations in 1994 as an internal services
business. The shared service center in Allentown, Pennsylvania provides
centralized functions covering broad finance and administrative services
formerly supplied within each IMS HEALTH division, in the United States and
Canada, but at lower cost with higher levels of service. In 1998 effective with
the Cognizant Spin-off, the center began servicing Nielsen Media Research as an
external services provider in the functions of general accounting, accounts
payable, payroll and financial systems support.

FOREIGN OPERATIONS

      As indicated above, IMS HEALTH and its subsidiaries engage in a
significant portion of their business outside of the United States. IMS HEALTH's
foreign operations are subject to the usual risks inherent in carrying on
business outside of the United States, including fluctuation in relative
currency values, possible nationalization, expropriation, price controls and
other restrictive government actions. IMS HEALTH believes that the risk of
nationalization or expropriation is reduced because its products are software,
services and information, rather than the production of products which require
manufacturing facilities or the use of natural resources.

INTELLECTUAL PROPERTY

      IMS HEALTH owns and controls a number of patents, trade secrets,
confidential information, trademarks, trade names, copyrights and other
intellectual property rights which, in the aggregate, are of material importance
to its business. Management believes that the "IMS" name and related names,
marks and logos are of material importance to IMS HEALTH. IMS HEALTH is licensed
to use certain technology and other intellectual property rights owned and
controlled by others, and similarly, other companies are licensed to use certain
technology and other intellectual property rights owned and controlled by IMS
HEALTH. The technology and other intellectual property rights licensed by IMS
HEALTH are of importance to its business, although management of IMS HEALTH
believes that IMS HEALTH's business, as a whole, is not dependent upon any one
intellectual property or group of such properties.

      The names of IMS HEALTH's and its subsidiaries' products and services
referred to herein are trademarks, service marks, registered trademarks or
registered service marks owned by or licensed to IMS HEALTH or one of its
subsidiaries.

                         RELATIONSHIP BETWEEN IMS HEALTH
                AND NIELSEN MEDIA RESEARCH AFTER THE DISTRIBUTION

      Prior to the Cognizant Spin-off, IMS HEALTH and Cognizant (which changed
its name to Nielsen Media Research, Inc.) entered into certain agreements
governing their relationship subsequent to the Cognizant Spin-off and providing
for the allocation of certain liabilities and obligations arising from periods
prior to the Cognizant Spin-off, including those obligations and liabilities
that arose in connection with the D&B Spin-off. The following descriptions
summarize certain terms of such agreements, but is qualified by reference to the
texts of such agreements, which are incorporated by reference to the Exhibits to
this Form 10-K.

DISTRIBUTION AGREEMENT

      Cognizant and IMS HEALTH entered into a Distribution Agreement (the
"Distribution Agreement") providing for, among other things, certain corporate
transactions required to effect the Cognizant Spin-off and other arrangements
between Cognizant and IMS HEALTH subsequent to the Cognizant Spin-off.

      In particular, the Distribution Agreement defines the assets and
liabilities which were allocated to and assumed by IMS HEALTH and those which
are allocated to and assumed by Nielsen Media Research. All assets were
transferred without any representation or warranty, "as is-where is", and the
relevant transferee bears the risk that any necessary consent to transfer was
not obtained.

      The Distribution Agreement provides for, among other things, assumption of
liabilities and cross indemnities designed to allocate generally, effective as
of the Distribution Date, financial responsibility for the liabilities arising
out of or in connection with (i) Cognizant's businesses (i.e., Nielsen Media
Research) and certain other specified liabilities and (ii) all other liabilities
to IMS HEALTH. Pursuant to the terms of the 1996 Distribution Agreement (the
"1996 Distribution Agreement") among Cognizant, Dun & Bradstreet and ACNielsen
Corporation ("ACNielsen"), as a condition to the Distribution, IMS HEALTH and
Nielsen Media Research were required to and did undertake to be jointly and
severally liable to Dun & Bradstreet and ACNielsen for any liabilities arising
thereunder. The Distribution Agreement allocates between IMS HEALTH and


                                       8
<PAGE>

Nielsen Media Research the financial responsibility for such liabilities
including contingent liabilities related to certain prior business transactions
and certain liabilities to Dun & Bradstreet that may arise in connection with
the D&B Spin-off.

      Among other things, IMS HEALTH and Nielsen Media Research agreed to an
allocation of certain potential liabilities in connection with the action filed
by Information Resources, Inc. described in Note 15 of the Notes to Consolidated
Financial Statements in the 1998 Annual Report to Shareholders, referred to in
Item 3 Legal Proceedings (the "IRI Action"). IMS HEALTH and Nielsen Media
Research have agreed that, as between themselves, IMS HEALTH will assume 75%,
and Cognizant will assume 25%, of any payments to be made by Cognizant in
respect of IRI Action under the 1996 Indemnity and Joint Defense Agreement among
Cognizant, Dun & Bradstreet and ACNielsen (the "IJDA") including any legal fees
and expenses incurred in 1999 or thereafter. IMS HEALTH agreed to be fully
responsible for any legal fees and expenses incurred during 1998. Nielsen Media
Research aggregate liability to IMS HEALTH for payments in respect of the IRI
Action and certain other specified contingent liabilities is not to exceed $125
million. Under the IJDA, ACNielsen assumed exclusive liability for the IRI
Liabilities up to a specified amount (the "ACN Maximum Amount"), which is to be
calculated at the time such liabilities, if any, become payable, and that
Cognizant and Dun & Bradstreet 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 is 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.

      In addition, pursuant to the Distribution Agreement, on the Distribution
Date, Nielsen Media Research contributed to IMS HEALTH all cash in Nielsen Media
Research accounts other than (i) cash required by Nielsen Media Research to
satisfy certain specified obligations and (ii) such additional cash as was
necessary for the net borrowings of Nielsen Media Research (excluding the items
referred to in clause (i)) to be $300 million as of the Distribution Date.

      The Distribution Agreement provides that neither Nielsen Media Research
nor IMS HEALTH will take any action that would jeopardize the intended tax
consequences of the Cognizant Spin-off. Specifically, each company agrees to
maintain its status as a company engaged in the active conduct of a trade or
business, as defined in Section 355(b) of the Internal Revenue Code, until the
second anniversary of the Distribution Date. As part of the request for a ruling
that the Cognizant Spin-off will be tax free for Federal income tax purposes,
each company represented to the Internal Revenue Service that, subject to
certain exceptions, it has no plan or intent to liquidate, merge or sell all or
substantially all of its assets. As a result, the Company may not initiate any
action leading to a change of control, and in the case of a change in control,
the foregoing representations, and the ruling based thereon, could be called
into question. As a result, the acquisition of control of the Company prior to
July 1, 2000 may be more difficult or less likely to occur because of the
potential substantial contractual damages associated with a breach of such
provisions of the Distribution Agreement.

TAX ALLOCATION AGREEMENT

      Nielsen Media Research and IMS HEALTH entered into a Tax Allocation
Agreement under which IMS HEALTH agreed to pay any taxes, or receive any refunds
or credits of taxes, shown as due on a U.S. federal, state or local income or
franchise tax return for a taxable period beginning prior to the Distribution
Date (including the current taxable period to the extent such taxes, refunds or
credits are attributable to the portion of such taxable period up to and
including the Distribution Date). Any subsequent adjustment of such taxes will
be allocated to IMS HEALTH if such adjustment relates to IMS HEALTH's business
and to Cognizant if such adjustment relates to the Nielsen Media Research
business, except that any adjustment of such taxes attributable to tax items or
positions initially determined by Cognizant's corporate office will be allocated
to IMS HEALTH.

      All taxes other than U.S. federal, state and local income and franchise
taxes will be the responsibility of IMS HEALTH if they are attributable to IMS

EMPLOYEE BENEFITS AGREEMENT

      Nielsen Media Research and IMS HEALTH entered into an Employee Benefits
Agreement, which allocates responsibility for certain employee benefits matters
on and after the Distribution Date. Among other things, the Employee Benefits
Agreement requires that the Company adopt a defined pension plan, nonqualified
supplemental pension plans and welfare plans for the benefit of IMS HEALTH
employees and former employees. Nielsen Media Research is required to continue
to sponsor its current defined benefit pension plans and welfare plans for the
benefit of employees and former employees and will retain the liability for
benefits under Nielsen Media Research nonqualified supplemental pension plans
for such employees. Nielsen Media Research and IMS HEALTH will each generally
retain the severance liabilities of their respective employees who terminated
employment prior to the Distribution Date. Assets and liabilities of the
Cognizant Pension Plan attributable to the Company's employees and retirees were
transferred to a plan maintained by the Company.

AMENDED AND RESTATED TRANSITION SERVICES AGREEMENT

      Nielsen Media Research, IMS HEALTH, Dun & Bradstreet, R.H. Donnelley,
Inc., ACNielsen and Gartner entered into an Amended and Restated Transition
Services Agreement pursuant to which such parties have agreed to certain basic
terms governing the provision by Dun & Bradstreet to the other parties of
insurance and risk management services for a transitional period after the
Distribution Date. The Amended and Restated Transition Services Agreement amends
and restates in its entirety the Transition Services Agreement dated as of
October 28, 1996 among Cognizant, Dun & Bradstreet and ACNielsen entered into in
connection with the D&B Spin-off and includes Gartner as a party to such
agreement.

                     FACTORS THAT MAY AFFECT FUTURE RESULTS

      From time to time, information and statements provided by the Company may
contain "forward-looking statements" as defined by the Private Securities
Litigation Reform Act of 1995. The Company cautions shareholders and investors
that actual results may differ materially from those projected or suggested in
any forward-looking statement as a result of a wide variety of factors,
including but not limited to the factors set forth below:

      o     Many existing computer systems and software applications use two
            digits, rather than four, to record years. Unless modified, such
            systems will not properly record or interpret years after 1999,
            which could lead to business disruptions ("the Year 2000 issue").
            The Company began to address the Year 2000 issue in 1996, when it
            began to assess the impact on its operations. 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 Company has identified its Year 2000 areas of focus as systems
            and software for the creation and delivery of its products and
            systems and software for its internal administrative operations.

      o     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 Company's plans are dependent on the continuous
            operation of industries outside of its direct control such as
            utilities, transportation, etc. 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. See the "Financial Review" in the 1998 Annual
            Report to Shareholders.

      o     Results could be affected by the costs and other effects of
            litigation and other contingencies involving the Company. In
            particular, management of the Company is unable to predict at this
            time the final outcome of the IRI Action described in "Note 15.
            Contingencies" of the Notes to Consolidated Financial Statements in
            the 1998 Annual Report to Shareholders, or whether the resolution of
            this matter could materially affect the Company's results of
            operations, cash flows or financial position.

      o     The Company has been informed by The Dun & Bradstreet Corporation
            ("D&B") that the IRS is currently reviewing D&B's utilization of
            certain 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 is made
            and the IRS prevails would be approximately $425,000 for taxes and
            accrued interest net of tax benefit. Under the terms of the 1996
            Distribution Agreement, the Company is liable to pay half of such
            taxes and interest owed to the extent that D&B's total liabilities
            exceed $137,000. A portion of the Company's liabilities would in
            turn be shared with Nielsen Media Research in connection with the
            Distribution dated June 30, 1998 between Cognizant and the Company.
            The Company estimates that its current share of the Liability were
            the IRS to prevail would be approximately $135,000. Additional
            information is incorporated by reference to Note 12. Income Taxes on
            Pages 30 - 31 of the 1998 Annual Report to Shareholders.

                                       10

      o     The Company operates globally, deriving 59% of its $1,186,513 in
            revenue and 114% of its $132,484 in operating income from non-U.S.
            operations. As a result, fluctuations in the value of foreign
            currencies relative to the U.S. dollar may increase the volatility
            of U.S. dollar-denominated operating results. The Company's
            geographic expansion in emerging markets such as Eastern Europe,
            Africa and Asia Pacific is expected to continue. Emerging markets
            tend to be considerably less stable than established markets which
            may further contribute to volatility in operating results. In
            addition, the Company is subject to the usual risks inherent in
            carrying on business in certain countries outside the United States,
            including possible nationalization, expropriation, price controls or
            other restrictive government actions. Management believes that the
            risk of nationalization or expropriation is reduced because its
            basic service is the delivery of information, rather than the
            production of products which require manufacturing facilities or use
            of natural resources.

      o     Although an important aspect of the Company's business strategy is
            growth through acquisitions, there can be no assurance that
            management of the Company will be able to identify and consummate
            acquisitions on satisfactory terms. Furthermore, every acquisition
            will entail some degree of uncertainty and risk, and even if
            consummated, may not produce the operating results or increases in
            value over time which were expected at the time of acquisition.

      o     The Company competes in businesses which demand or sell
            sophisticated information systems, software and other technology.
            The types of systems which the Company's businesses require or sell
            can be expected to be subject to refinements as such systems and
            underlying technologies are upgraded and advanced, and there can be
            no guarantee that as various systems and technologies become
            outdated, the Company will be able to replace them, to replace them
            as quickly as the Company's competition or to develop and market new
            and better products and services in the future on a cost-effective
            basis.

      o     Currently, the Company's assets include a significant block of the
            outstanding shares of Gartner. In the third quarter of 1997, the
            Company's voting interest in Gartner fell below 50% to 49.5% based
            upon the exercise of Gartner employee stock options and employee
            stock purchases. Accordingly, as of September 30, 1997 the Company
            deconsolidated Gartner and is accounting for its ownership interest
            on the equity basis. Gartner's common stock has historically traded
            at higher multiples than market averages and has generally
            experienced greater price volatility than the market as a whole. It
            can be expected that variations in the market value of the Gartner
            shares held by the Company will have an impact on the trading prices
            of the Company's Common Stock. Gartner's results of operations may
            also be subject to the various factors described in Gartner's
            reports filed with the SEC from time to time.

      o     A number of countries in which the Company operates have enacted
            regulations limiting the prices pharmaceutical companies may charge
            for drugs. The Company believes that such cost containment measures
            will cause pharmaceutical companies to seek more effective means of
            marketing their products (which will benefit the Company in the
            medium and long term). However, such governmental regulation may
            cause pharmaceutical companies to revise or reduce their marketing
            programs in the near term.

      o     Certain of the data services provided by the Company relate to the
            diagnosis and treatment of disease. The use of patient-specific
            information is anticipated to be an increasingly important tool in
            the design, development and marketing of pharmaceuticals. To protect
            privacy, no individual patient is identified in any IMS database.
            Recently, there have been a number of regulatory and legislative
            initiatives in the area of medical privacy at the federal, state and
            foreign government levels. Most of these initiatives seek to place
            restrictions on the use and disclosure of patient-identifiable
            information without consent and consequently would not apply to the
            Company's business. However, there can be no assurance that future
            initiatives would not adversely affect the Company's ability to
            generate or assemble data or to develop or market current or future
            products and services.

      o     Each of the Company's businesses is subject to significant or
            potential competition which is likely to intensify in the future.

      o     The Company's results could be adversely affected by general or
            specific weakening of economic conditions, including weak economic
            conditions in the pharmaceutical, healthcare, information technology
            or other industries in which the Company's customers operate.

      o     On November 11, 1998 the Company announced that its Board of
            Directors approved a plan, in principle, to spin-off substantially
            all of its equity ownership of Gartner. The transaction, expected to
            be completed in the first half of 1999, is to be structured as a
            tax-free distribution of Gartner Stock to IMS HEALTH shareholders.
            The transaction is subject to receipt of a favorable ruling from the
            IRS, final approval by the Company's and Gartner's Board of
            Directors, and approval by Gartner shareholders. Additional
            information is incorporated by reference to the Financial Review on
            pages 1-12 of the 1998 Annual Report to Shareholders.

       REPORT OF INDEPENDENT ACCOUNTANTS ON FINANCIAL STATEMENT SCHEDULE

To the Board of Directors
of IMS Health Incorporated:

      Our audits of the consolidated financial statements referred to in our
report dated February 16, 1999 appearing in the 1998 Annual Report to
Shareholders of IMS Health Incorporated ("accounting successor to Cognizant
Corporation") (which report and consolidated financial statements are
incorporated by reference in this Annual Report on Form 10-K) also included an
audit of the financial statement schedules listed in Item 14(a)(2) of this Form
10-K. In our opinion, this financial statement schedule presents fairly, in all
material respects, the information set forth therein when read in conjunction
with the related consolidated financial statements.

IMS HEALTH INCORPORATED

FINANCIAL REVIEW

Dollar amounts in thousands, except per share data
- - --------------------------------------------------------------------------------

     All share and per share data presented are adjusted to reflect a 2-for-1
stock split distributed to shareholders on January 15, 1999. (See Note 2. to the
Consolidated Financial Statements).

YEAR-ENDED DECEMBER 31, 1998 COMPARED WITH
   YEAR-ENDED DECEMBER 31, 1997

     The accompanying financial statements and related financial review relate
to IMS Health Incorporated ("IMS Health" or the "Company"). On June 30, 1998,
the common stock of IMS Health was distributed by Cognizant Corporation
("Cognizant") to its shareholders. Simultaneously with the distribution (the
"Distribution"), Cognizant changed its name to Nielsen Media Research, Inc.
("Nielsen Media Research"). Notwithstanding the legal form of the Distribution,
whereby Cognizant spun off IMS Health, for accounting purposes the transaction
is accounted for as if Cognizant spun off Nielsen Media Research and IMS Health
has been deemed the "accounting successor" to Cognizant. 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, Inc. ("Enterprises"), a 61.7% interest in Cognizant
Technology Solutions Corporation ("CTS") and SSJ K.K. ("Super Systems Japan").
The Company also has an equity investment in Gartner Group, Inc. ("Gartner").

     Pursuant to Accounting Principles Board ("APB") Opinion No. 30, "Reporting
the Results of Operations--Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions," the consolidated financial statements of the Company have been
reclassified to reflect the results of Nielsen Media Research as a discontinued
operation. (See Note 1. to the Consolidated Financial Statements).

Investment in Gartner

     In September 1997, the Company's voting interest in Gartner fell below 50%
as a result of the exercise of Gartner employee stock options and employee stock
purchases. Accordingly, in the third quarter of 1997, the Company deconsolidated
Gartner (the "Gartner Deconsolidation") and as of January 1, 1997 is accounting
for its ownership interest on the equity basis. (See Note 3. to the Consolidated
Financial Statements).

     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. The transaction, expected to be completed in the first half of 1999, is
to be structured as a tax-free distribution of Gartner stock to IMS Health
shareholders. The transaction is subject to receipt of a favorable ruling from
the Internal Revenue Service ("IRS") regarding the tax free nature of the
proposed transaction, final approval by the Company's and Gartner's Boards of
Directors, and approval by Gartner shareholders.

     At December 31, 1998, the Company owned approximately 47 million shares of
Gartner. Prior to the proposed spin-off transaction, 40.1 million of these
shares will be exchanged for new Class B Common Stock of Gartner. The Class B
Stock will be entitled to elect 80% of Gartner's Board of Directors, but will
otherwise be identical to existing Class A Common Stock. The exchange will be
part of a Gartner recapitalization and requires approval by Gartner
shareholders. The Class B shares will be distributed to the Company's
shareholders in a tax-free distribution, subject to receipt of a favorable tax
ruling from the Internal Revenue Service with respect to the distribution. The
Company intends to monetize its remaining position in Gartner through the first
quarter of the Year 2000. This includes 6.9 million shares of Class A Common
Stock and warrants to purchase a further 600,000 shares.

     Separately, Gartner announced that subject to approval by the IRS of the
tax-free treatment of the distribution, it intends to declare a special one-time
cash dividend of $300,000 to its shareholders of record immediately prior to the
spin-off. The Gartner Board of Directors has authorized a $300,000 open market
share repurchase program for up to 20% of its stock commencing immediately after
the spin-off.

Dispositions

     During the year, the Company recorded $46,118 net pre-tax gains principally
reflecting the sale of investments in Aspect Development, Inc., which is part of
Enterprises' portfolio and the sale of shares in CTS. (See Note 6. to the
Consolidated Financial Statements). These sales generated cash proceeds of
$78,883.

Acquisitions and Joint Venture

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

     Under the terms of the Walsh acquisition agreement, Walsh shareholders
received .6082 (on a pre-split basis the ratio is .3041) shares of Cognizant
common stock per Walsh share or based on a Cognizant share price of $25.896,
consideration of approximately $167,148 (on a pre-split basis a Cognizant share
price of $51.792). Walsh had 10,612,628 shares outstanding. Cognizant issued


                                                                               1

6,454,600 shares from treasury stock to consummate the Walsh acquisition. The
direct acquisition and integration costs consist of severance of $4,876, lease
terminations of $2,569, and other direct acquisition and integration costs of
$9,634. These direct acquisition and integration costs were incurred as a direct
result of the acquisition and the formal 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). To date,
incurred acquisition and integration costs are within original estimates.
Approximately $156,557 is 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.

     The severance costs are related to 78 Walsh employees. As of December 31,
1998, the Company made payments of $3,257, reducing the work force by 56, and
the remaining terminations are anticipated to be completed by June 1999. The
following table displays the activities since the acquisition with respect to
these liabilities:

     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 $75,292 of common stock, $5,415 of stock
options and $22,584 of accrued acquisition and integration costs.

     Under the terms of the PMSI acquisition agreement, PMSI received 2,395,926
shares of IMS Health common stock. The direct acquisition and integration costs
consist of severance of $3,794, lease terminations of $1,623, contract
cancellations of $10,935, and other direct acquisition and integration costs of
$6,232. These direct acquisition and integration costs are incremental to other
costs and 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). Acquisition and integration costs incurred to date
are within original estimates. Approximately $115,275 is 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.

     The severance costs are related to 63 PMSI employees. As of December 31,
1998, the Company made payments of $2,013 reducing the work force by 33, and the
remaining terminations are anticipated to be completed by July 1999. The

Joint Venture

     On September 1, 1998, the Company formed a joint venture with IHA Institut
fur Marktanalysen AG ("IHA"). The Company and IHA each contributed all of their
Swiss pharmaceutical research assets to the venture and each own 50% of the
venture. The Company contributed assets of $54 and cash of $11,014. The $12,027
excess of the investment over the value of the Company's share of the net assets
has been recorded as goodwill, which is being amortized on a straight line basis
over 20 years. The Company has accounted for its ownership interest in the joint
venture under the equity method. 

Purchase Price Allocation

     The Company made allocations of the aggregate 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.

     The Securities and Exchange Commission (the "SEC") recently issued revised
guidance with respect to allocations of IPR&D projects in connection with
acquisitions. In accordance with this guidance, 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.

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

     In the aggregate, the impact of both the Walsh and PMSI acquisitions on the
results of operations, other than the one-time charges and IPR&D write-offs, had
they occurred on January 1, 1998 or 1997, would be immaterial.

     At the date of the respective acquisitions, the development of the IPR&D
projects had not yet reached technological feasibility and had no alternative
future use. Accordingly, these costs were expensed as of the respective
acquisition dates.

     The projects identified as IPR&D at Walsh include enhancement of Walsh's
Windows-based sales manage-ment information system, enhancement of its
pharmaceutical marketing database, and development of a next-stage integrated
and enhanced sales management information system. These projects were identified
as underway at Walsh and, at the date of the acquisition, would require
additional effort to establish technological feasibility. In addition, based on
a third party independent appraiser, the Company allocated $29,000 to existing
core technology representing computer software that is currently in use, which
is being amortized over 5 years.

     The projects identified as IPR&D at PMSI include significant improvements
of PMSI's physician database products in Europe and Japan and to its pharmacy
software system in the United Kingdom. These projects were identified as being
underway at PMSI, at the date of acquisition, and would require additional
effort to establish technological feasibility. In addition, based on a third
party independent appraiser, the Company allocated $7,700 to existing core
technology representing computer software that is currently in use, which is
being amortized over 5 years.

     The amounts assigned to the IPR&D projects were determined by first
estimating the degree of completion of each project and the potential net cash
flows from such projects after commercial introduction. The potential net cash
flows include reductions reflecting the necessary investment in fixed and
working capital and other collateral assets, which include core technology,
where appropriate and a fair return on those assets. A portion of the potential
net cash flows for each project was then attributed to the effort already
completed by Walsh and PMSI by the acquisition date, based upon the estimated
degree of completion. The attributed potential net cash flows for each project
were discounted to present value using a risk-adjusted discount rate.

     The discount rates utilized to value the IPR&D projects ranged from 17% to
30%. Such discount rates took into account the industry risk for the Walsh and
PMSI businesses acquired (as evidenced by the calculated weighted average cost
of capital), technological development risk associated with completing the
in-process projects, and market and commercial risk associated with introducing
the new products/technology. The implied weighted average cost of capital for
the different Walsh and PMSI projects ranged from 12% to 15%.

     The degree of completion represents the extent to which the different
in-process projects are complete, as of the respective acquisition dates. The
completion percentage ranged from 53% to 87% for projects at Walsh and 80% to
90% for projects at PMSI. In the opinion of management, IMS Health is on target
to begin realizing the benefits from these various projects through product
introductions at launch dates ranging from early 1999 to January 2000.

     The Company believes that the assumptions used, including the revenue
forecasts and margin analysis, are reasonable. No assurance can be given,
however, that the underlying assumptions used to estimate expected project
sales, development costs or profitability, or the events associated with such
projects, will transpire as estimated. For these reasons, actual results may
vary from the projected results.

     Management expects to continue supporting these IPR&D efforts and believes
the Company has a reasonable chance of successfully completing the IPR&D
programs. However, there is risk associated with the completion of the IPR&D
projects and the Company cannot be assured that any will meet with either
technological or commercial success.

     If none of these IPR&D projects are successfully developed, the sales and
profitability of the Company may be adversely affected in future periods. The
failure of any particular individual project in-process would not materially
impact the Company's financial condition, results of operations or cash flows.
Operating results are subject to uncertain market events and risks, which are
beyond the Company's control, such as trends in technology, government
regulations, market size and growth, and product introduction or other actions
by competitors.

     In connection with the PMSI acquisition, the Company commenced an
evaluation of its existing IMS Health product offerings. Based on this strategic
assessment, the Company decided to abandon certain of its existing 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 and is included as a component of operating income.


                                                                               3

Public Offering of a Subsidiary

     On June 19, 1998, CTS effected an initial public offering (the "CTS IPO")
of 2,917,000 shares of Class A Common Stock, par value $0.01 per share
(3,354,550 including the underwriters' over-allotment option granted by
Cognizant). Cognizant's interest in CTS was transferred to the Company in the
Distribution. The Company's ownership interest was 61.7% at December 31, 1998
and, accordingly, the Company consolidates CTS results within its financial
statements. The equity not owned by the Company is reflected on the Statement of
Financial Position in the minority interest line and on the Consolidated
Statements of Income in the Other Expense-Net line. (See Note 6. to the
Consolidated Financial Statements).

Operating Results

     Revenue in 1998 increased 12.0% to $1,186,513 from $1,059,559 in 1997. This
increase primarily reflects the strong growth of the core IMS worldwide
business. The core IMS worldwide revenues benefited from the introduction of new
compounds within the pharmaceutical client base, new product introductions,
acquisition-related revenue and geographic expansion. Adjusting for the impact
of a stronger U.S. dollar, 1998 revenue increased by 15.4%.

     Operating costs and selling and administrative expenses in 1998 were
$1,054,029, compared with $831,949 in 1997, an increase of 26.7%. This increase
was due primarily to the Company's increased spending on new revenue growth
initiatives, increased spending on the Year 2000 ("Y2K") issue, charges related
to the Distribution (approximately $35,000), one-time charges and IPR&D
write-offs related to the Walsh and PMSI acquisitions, and incremental recurring
expenses related to the two acquired businesses. If these 1998 expenses are
adjusted to exclude the charges related to the Distribution, the one-time
charges and IPR&D write-offs related to the Walsh and PMSI acquisitions, Y2K
costs, operating costs and selling and administrative expenses increased by
7.4%, to $893,263 in 1998.

     Operating income in 1998 decreased 41.8% to $132,484 from $227,610 in 1997.
This decrease primarily reflects the impact of increased spending on the Y2K
issue, charges related to the Distribution, one-time charges and IPR&D
write-offs related to the Walsh and PMSI acquisitions, and the operations of
Walsh and PMSI. If 1998 operating income is adjusted to exclude the charges
related to the Distribution, the one-time charges and IPR&D write-offs related
to the Walsh and PMSI acquisitions, Y2K costs, operating income increased by
28.8%, to $293,250 in 1998. This operating income growth outpaced revenue growth
primarily due to the Company's ability to leverage its worldwide resources.

     Operating margin in 1998 was 11.2%, compared with 21.5% in 1997. If the
1998 operating margin is adjusted to exclude the items listed above, operating
margin improved to 24.7% in 1998 from 21.5% in 1997. The IMS segment operating
margin was 28.6% in 1998 compared with 28.1% in 1997.

     Non-operating income-net (including interest income and expense) in 1998
was $138,177, compared with $94,864 in 1997. The increase was principally due to
gains from the CTS IPO and the sale of assets from the Enterprises portfolio,
increased Gartner Equity Income and higher net interest income.

     The Company's consolidated 1998 effective tax rate was 34.1%, compared with
27.4% in 1997. The Company's higher tax rate in 1998 reflects non-deductible
charges related to the Distribution, and the one-time charges and IPR&D
write-offs related to the Walsh and PMSI acquisitions, and the continued impact
of global tax planning strategies.

     Income from continuing operations in 1998 was $178,465, compared with
$234,116 in 1997, a decrease of 23.8%. This decrease was due principally to
increased spending on the Y2K issue, charges related to the Distribution,
one-time charges and IPR&D write-offs related to the Walsh and PMSI
acquisitions, partially offset by gains from the CTS IPO, the sale of assets
from the Enterprises portfolio and a pre-tax unrealized gain on its investment
in Gartner ("SAB 51 Gain"). Excluding these items, income from continuing
operations increased 25.5% to $271,815 in 1998 from $216,634 in 1997, reflecting
the strong growth of the core IMS worldwide business.

     Income from discontinued operations, net of income taxes in 1998 was
$42,093 (which includes the first six months of Nielsen Media Research's 1998
operations), compared to $78,234 in 1997 (which includes a full year of Nielsen
Media Research's operations).

     Net income in 1998 was $220,558, compared with $312,350 in 1997, a decrease
of 29.4%. This decrease principally reflects the items noted above in income
from continuing operations and the inclusion of only six months of Nielsen Media
Research's 1998 operations.

RESULTS BY BUSINESS SEGMENT

IMS

     The IMS segment consists of IMS, the leading global provider of market
information, sales management and decision-support services to the
pharmaceutical and healthcare industries, and Strategic Technologies, a leading
provider of automated sales support technologies to the pharmaceutical industry.
IMS segment revenue increased 10.6% in 1998 to $1,083,992 from $980,521 in 1997.
This

- - --------------------------------------------------------------------------------

growth reflected strong performance of core business services, increased demand
for services due to introduction of new compounds within the pharmaceutical
client base, geographic expansion, the impact of the Walsh and PMSI
acquisitions, and strong revenue growth at Strategic Technologies. Excluding the
impact of a stronger U.S. dollar in 1998, revenue growth was 14.1%. Operating
income decreased 30.4% to $184,771 in 1998 from $265,351 in 1997. Excluding the
one-time charges and IPR&D write-offs related to the Walsh and PMSI
acquisitions, and Y2K costs in 1998, operating income growth was 17.0% due to
the factors described above. Operating income growth outpaced revenue growth
primarily due to the segment's ability to leverage its worldwide resources.

EMERGING MARKETS

     The Emerging Markets segment consists primarily of Erisco, and also
includes Enterprises and Super Systems Japan. In the third quarter of 1997, the
Company sold Pilot and recorded a non-cash pre-tax loss of $29,945. Excluding
Pilot in 1997, the segment had a 21.7% increase in 1998 revenue to $57,542 from
$47,286 in 1997, primarily reflecting strong growth at Erisco. 1998 operating
income for the segment was $6,171 compared with a loss of $12,669 in 1997. This
improvement reflects the elimination of the Pilot losses, combined with strong
improvements in profitability at Erisco.

CTS

     CTS revenue, excluding sales to related parties, increased 224.1% to
$44,979 in 1998 from $13,879 in 1997. This growth reflected the addition of new
customers and the continuing conversion of Y2K customers into ongoing
development and maintenance customers. Operating income, excluding the operating
profit associated with related parties, increased 205.7% to $8,918 in 1998 from
$2,917 in 1997. The strong revenue growth was partially offset by the continued
acceleration of sales and marketing investments and increased infrastructure to
support revenue growth.

GARTNER

     Gartner is the world's leading independent provider of research and
analysis on the computer hardware, software, communications and related
information technology industries. As discussed earlier, the Company's voting
interest in Gartner fell below 50% in September 1997. Accordingly, the Company
accounts for its ownership interest on the equity basis. In both 1997 and 1998,
the income statement impact of the Company's ownership interest appears in
non-operating income-net as Gartner equity income and as a pre-tax unrealized
gain on Gartner stock (included as a separate line ("SAB 51") in the income
statement). Gartner Equity Income grew by 9.0% to $70,979 in 1998 from $65,120
in 1997. SAB 51 gains grew by 1.0% to $14,838 in 1998 from $14,689 in 1997. A
SAB 51 Gain was not recognized in the fourth quarter of 1998 due to the
announcement of the spin-off of the Company's equity investment in Gartner (See
Note 3. to the Consolidated Financial Statements).

RESULTS BY GEOGRAPHIC AREA

     Revenue in the United States increased by 19.6% to $489,719 in 1998 from
$409,527 in 1997. The increase reflected the strong performance of core business
services by the IMS segment, high revenue growth at Erisco and CTS through the
addition of new customers and new product introductions and the Walsh
acquisition.

     Non-U.S. revenue increased 7.2% to $696,794 in 1998 from $650,032 in 1997.
Non-U.S. operations include Europe, Australia and the Far East. The increase
reflects continued growth of IMS, new product introductions, geographic
expansion by IMS and the impact of the Walsh and PMSI acquisitions. Excluding
the impact of a stronger U.S. dollar in 1998, non-U.S. revenue increased by
12.7%.

YEAR-ENDED DECEMBER 31, 1997 COMPARED WITH
   YEAR-ENDED DECEMBER 31, 1996

     In September 1997, the Company's voting interest in Gartner fell below 50%
as a result of the exercise of Gartner employee stock options and employee stock
purchases. Accordingly, in the third quarter, the Company deconsolidated Gartner
as of January 1, 1997 and is accounting for its ownership interest on the equity
basis.

     Revenue in 1997 decreased 24.9% to $1,059,559 from $1,411,192 in 1996. This
decrease primarily reflects the impact of the Gartner Deconsolidation. Revenue
in 1997 increased by 10.2%, excluding Gartner revenue from both years and the
impact of a stronger U.S. dollar. The increase reflects double-digit revenue
growth in the IMS segment, partially offset by Pilot, which was sold in the
third quarter of 1997. IMS segment revenue growth benefited from strong
performance of its core business services, geographic expansion and excellent
growth of its electronic territory management product. The impact of a stronger
U.S. dollar in 1997 reduced revenue growth by approximately 3%.

     Operating costs and selling and administrative expenses in 1997 were
$831,949 compared with $1,167,485 in 1996, a decrease of 28.7%. This decrease
primarily reflects the impact of the Gartner Deconsolidation. Excluding Gartner
expenses from both years and business units sold in 1996, operating costs and
selling and administrative expenses increased 4.0% to $831,949 in 1997 from
$799,939 in 1996. This increase reflects the Company's increased spending on new
revenue growth initiatives

which contributed to revenue growth of 10.2% in 1997. The impact of a stronger
U.S. dollar in 1997 decreased operating costs and selling and administrative
expenses by approximately 3%.

     Operating income in 1997 decreased 6.6% to $227,610 from $243,707 in 1996.
This decrease primarily reflects the impact of the Gartner Deconsolidation.
Excluding Gartner operating income in both years and sold business units in
1996, operating income increased 21.8% to $227,610 in 1997 from $186,871 in
1996. Operating income growth outpaced revenue growth primarily due to IMS's
ability to leverage its resources. The impact of a stronger U.S. dollar in 1997
decreased reported operating income by approximately 1%. The sale of Pilot,
which had been generating an operating loss, enabled the Company to redeploy
resources to strategic technology investments, including the initiative to
accelerate Y2K compliance. The impact on operating income of Y2K compliance was
$9,819 in 1997.

     Operating margin in 1997 was 21.5%, compared with 17.3% in 1996. Excluding
Gartner results from both years, and discontinued business units in 1996,
operating margin was 21.5% in 1997 compared with 18.9% in 1996.

     Non-operating income-net in 1997 was $94,864, compared with $5,853 in 1996.
The increase was due principally to recording $65,120 of Gartner equity income
in 1997 as a result of the Gartner Deconsolidation. The Company also recognized
a SAB 51 Gain of $14,689 (included as a separate line in the income statement)
corresponding to the net increase in the underlying value of its investment in
Gartner. In addition, non-operating income-net for 1997 includes gains of
$39,336 related to the disposition of Enterprises' investment in WEFA Group,
Inc. and a portion of its investment in TSI International, Inc. and Aspect
Development, Inc., and a $29,945 loss on the sale of Pilot (included in gains
from dispositions-net).

     The Company's consolidated 1997 effective tax rate was 27.4%, compared with
44.0% in 1996. The Company's lower tax rate in 1997 is due to the benefits of
global tax planning strategies.

     Income from continuing operations in 1997 was $234,116, compared with
$139,754 in 1996, an increase of 67.5%. This increase principally reflects IMS
operating income growth, gains from dispositions-net and SAB 51 gains in 1997
and a reduction in the tax rate from 44.0% in 1996 to 27.4% in 1997 due to
global tax planning actions. It also reflects a one-time after-tax
acquisition-related charge of $32,778 for IPR&D costs associated with Gartner's
acquisition of J3 Learning Corporation (the "J3 charge") in 1996. Excluding
these items, income from continuing operations increased 21.3% to $216,616 in
1997 from $178,597 in 1996.

     Income from discontinued operations, net of income taxes in 1997 was
$78,234, compared with $55,697 in 1996 an increase of 40.5%. Income from
discontinued operations, net of income taxes represents the results of Nielsen
Media Research. The increase is a result of a reduced tax rate of 27.4% in 1997
from 44.0% in 1996 and growth in Nielsen Media Research. Excluding this item and
Y2K expenses net of taxes in 1997, income from discontinued operations increased
12.1% over the prior year.

     Net income in 1997 was $312,350, compared with $195,451 in 1996, an
increase of 59.8%. This increase principally reflects the items noted above in
income from continuing operations and the reduction in the discontinued
operations tax rate. Excluding these items, net income increased 17.6% to
$294,850 in 1997 from $250,805 in 1996.

RESULTS BY BUSINESS SEGMENT

IMS

     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, an operating unit of IMS Health and the
leading provider of automated sales support technologies to the pharmaceutical
industry. IMS segment revenue increased 8.4% in 1997 to $980,521 from $904,444
in 1996. This growth reflected strong performance of core business services, new
product introductions, geographic expansion and strong revenue growth at
Strategic Technologies. Excluding the impact of a stronger U.S. dollar, revenue
growth was 11.4%. Operating income grew 14.0% to $265,351 in 1997 from $232,827
in 1996 due to the factors described above. Operating income growth outpaced
revenue growth primarily due to the segment's ability to leverage its resources.
Excluding the impact of Y2K compliance, a stronger U.S. dollar in 1997, and
business units sold in 1996, operating income grew 18.2%.

EMERGING MARKETS

     The Emerging Markets segment consists primarily of Erisco, and also
includes Enterprises, Pilot and Super Systems Japan. In the third quarter of
1997, the Company sold Pilot and recorded a non-cash pre-tax loss of $29,945.
The segment had a 17.7% decrease in 1997 revenue to $65,159 from $79,205 in
1996, reflecting the sale of Pilot. Erisco posted high revenue growth through
the addition of new customers and new product introductions. The 1997 operating
loss for the segment was $12,669, compared with $14,558 in 1996, reflecting the
sale of Pilot.

CTS

     CTS revenue, excluding sales to related parties, increased to $13,879 in
1997 from $3,161 in 1996. Operating income, excluding the operating profit
associated with re-lated parties, increased to $2,917 in 1997 from $1,655 in
1996. This growth reflected the impact of the addition of new customers.

GARTNER

     Gartner is the world's leading independent provider of research and
analysis on the computer hardware, software, communications and related
information technology industries. As discussed earlier, the Company's voting
interest in Gartner fell below 50% in September 1997. Accordingly, the Company
has deconsolidated Gartner and is accounting for its ownership interest on the
equity basis as of January 1, 1997. In 1997, the income statement impact of the
Company's ownership interest appears in non-operating income-net as Gartner
equity income and as a SAB 51 gain (included as a separate line in the income
statement). Revenue and operating income for Gartner in 1996 were $424,382 and
$60,114, respectively. Operating income was adversely affected by the J3 Charge.
Excluding this item, operating income was $93,347.

RESULTS BY GEOGRAPHIC AREA

     Revenue in the United States decreased by 36.0% to $409,527 in 1997 from
$639,831 in 1996. This decrease is primarily the result of the Gartner
Deconsolidation. Excluding Gartner and Pilot revenue in both years, 1997 revenue
in the United States increased by 18.7%. The increase reflected a strong
performance of core business services by IMS and high revenue growth at Erisco
and CTS through the addition of new customers and new product introductions.

     Non-U.S. revenue decreased by 15.7% to $650,032 in 1997 from $771,361 in
1996. The decrease is primarily the result of the Gartner Deconsolidation.
Excluding Gartner and Pilot revenue in both years and excluding the impact of a
stronger U.S. dollar, 1997 non-U.S. revenue increased by 10.7%. This increase
reflects continued growth at IMS and geographic expansion.

CHANGES IN FINANCIAL POSITION AT DECEMBER 31, 1998 
     COMPARED TO DECEMBER 31, 1997

     Cash and cash equivalents were $206,390, $312,442 and $422,963 at December
31, 1998, 1997 and 1996, respectively. Cash decreased $106,052 in 1998 primarily
due to payments for the purchase of treasury stock ($666,694) and investing
activities for capital expenditures, additions to software and other investments
($113,389). These cash uses were partially offset by proceeds from debt assumed
by Nielsen Media Research ($300,000), cash from operating activities ($229,842),
proceeds from exercise of stock options ($104,990) and proceeds from sale of
businesses and investments and issuance of subsidiary stock ($78,883).

     Accounts Receivable-Net increased to $324,219 at December 31, 1998, from
$251,623 at December 31, 1997, primarily reflecting the Walsh and PMSI
acquisitions and increases at IMS due to new product launches in the fourth
quarter and increased sales.

     Other Current Assets increased to $103,868 at December 31, 1998, from
$65,692 at December 31, 1997, primarily reflecting an increase in deferred
income taxes associated with tax deductible non-U.S. intangible assets.

     Investment in Gartner Group increased to $252,852 at December 31, 1998,
from $195,695 at December 31, 1997, primarily reflecting equity income-net of
taxes ($41,507) and a gain on the sale by Gartner of Gartner stock ($14,838).

     Goodwill increased to $363,841 at December 31, 1998, from $87,430 at
December 31, 1997, primarily reflecting the Walsh acquisition ($156,557) and the
PMSI acquisition ($115,275).

     Net Assets from Discontinued Operations decreased to $0 at December 31,
1998, from $122,778 at December 31, 1997, due to the Distribution of Nielsen
Media Research.

     Accounts and Notes Payable increased to $90,884 at December 31, 1998, from
$44,441 at December 31, 1997, primarily reflecting short term borrowings in
Japan and the inclusion of the liabilities related to the Walsh and PMSI
businesses.

     Accrued and Other Current Liabilities increased to $298,625 at December 31,
1998, from $189,384 at December 31, 1997, primarily reflecting the Walsh and
PMSI acquisitions and related acquisition costs.

     Deferred Income Taxes decreased to $30,322 at December 31, 1998, from
$92,153 at December 31, 1997, primarily reflecting long-term benefits associated
with tax deductible non-U.S. intangible assets.

     Other Liabilities increased to $181,807 at December 31, 1998, from $71,786
at December 31, 1997, primarily reflecting an increase in pre-spin liabilities.

NON-U.S. OPERATING AND MONETARY ASSETS

     The Company operates globally, deriving a significant portion of its
operating income from non-U.S. operations. As a result, fluctuations in the
value of foreign currencies relative to the U.S. dollar may increase the
volatility of U.S. dollar operating results. The Company enters into forward
contracts to offset the effect of currency fluctuations 


                                                                               7

on operating income. In 1998, foreign currency translation decreased U.S. dollar
revenue growth and operating income growth by approximately 3% and 8%,
respectively. In 1997, foreign currency translation decreased U.S. dollar
revenue growth and operating income growth by approximately 3% and 1%,
respectively.

     Non-U.S. monetary assets are maintained in currencies other than the U.S.
dollar, principally in those of Switzerland, Japan and Australia. Changes in the
value of these currencies relative to the U.S. dollar are charged or credited to
shareholders' equity. The effect of exchange rate changes during 1998 decreased
the U.S. dollar amount of cash and cash equivalents by $1,574.

LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents were $206,390, $312,442 and $422,963 at December
31, 1998, 1997 and 1996, respectively. Cash decreased $106,052 in 1998 primarily
due to payments for the purchase of treasury stock ($666,694) and investing
activities for capital expenditures, additions to software and other investments
($113,389). These cash uses were partially offset by proceeds from debt assumed
by Nielsen Media Research ($300,000), cash from operating activities ($229,842),
proceeds from exercise of stock options ($104,990) and proceeds from sale of
businesses and investments and issuance of subsidiary stock ($78,883).

     Net cash provided by operating activities was $229,842, $259,465 and
$257,059 in 1998, 1997 and 1996, respectively. The decrease of $29,623 in
operating activities in 1998 primarily reflected increased accounts receivable
from fourth quarter revenues ($46,001), higher taxes paid ($44,425) and
increased postemployment benefit payments ($6,671). These decreases were
partially offset by lower other working capital ($31,584) and higher tax
refunds. The increase of $2,406 in operating activities in 1997 primarily
reflected increased cash from operations, improved collections of accounts
receivable, the absence in 1997 of restructuring payments, and a lower level of
postemployment benefit and non-recurring charge payments. These increases were
partially offset by payment of income taxes in 1997 of $44,094.

     Net cash used in investing activities totaled $102,592 for 1998, compared
with $73,456 and $115,686 in 1997 and 1996, respectively. The cash usage in 1998
increased $29,136 reflecting payments for acquisitions and joint ventures
($38,356) and increases in other investments-net, partially offset by lower
capital expenditures ($16,158) and lower additions to computer software
($13,687). The decrease in cash usage in 1997 of $42,330 primarily reflected
higher proceeds from the sale of businesses and investments ($43,336) and the
absence of purchases of Gartner common stock ($49,419), offset in part by the
absence of net proceeds from marketable securities ($27,601).

     Net cash (used in)/provided by financing activities totaled ($214,555),
($215,198) and $80,609 for 1998, 1997 and 1996, respectively. Total financing
activity remained essentially unchanged in 1998 from 1997 with usage for the
purchase of treasury stock increasing ($341,927) and the absence of the 1997
minority interest financing ($100,000), offset by the proceeds of the debt
assumed by Nielsen Media Research ($300,000), higher proceeds from employee
stock option exercises ($78,581), increased short-term borrowing-net of
repayments ($34,008) and the proceeds from the sale and issuance of subsidiary
stock ($31,197). The increase in 1997 of cash used in financing activities
primarily reflected the purchase of shares of the Company's common stock
($324,767) and dividend payments ($19,883); partially offset by minority
interest financing $100,000 and proceeds from exercise of stock options $26,409.

     Cash flow (used by)/provided from discontinued operations totaled
($17,173), $53,580 and $47,694 for 1998, 1997 and 1996, respectively.

     The Gartner Deconsolidation resulted in the elimination of the Gartner
Group opening cash balances in 1997. Gartner Group cash balance as of December
31, 1996 was $123,697.

     On October 21, 1997 Cognizant announced that its board of directors had
authorized a systematic stock repurchase program to buy up to 20,000,000 shares
(on a post split basis) of Cognizant's outstanding common stock. As the
Accounting Successor to Cognizant, the Company purchased the remaining balance
of 18,850,800 shares of the Company's stock (on a post split basis) pursuant to
this program. A portion of this program was intended to offset option exercises.
This program was completed by the Company on November 17, 1998 at a cost of
$591,331.

     In the fourth quarter the Board of Directors authorized a stock repurchase
program to buy up to 16,000,000 shares (on a post split basis) of the Company's
outstanding common stock. A portion of this program is intended to offset option
exercises. Through December 31, 1998, 2,898,800 shares (on a post split basis)
have been acquired at a total cost of $98,113.

     In connection with the Distribution, Cognizant borrowed $300,000, which was
to repay existing intercompany liabilities. This debt was assumed by Nielsen
Media Research upon the Distribution.

     On November 11, 1998 the Company announced that its Board of Directors,
approved a plan, to spin-off substantially all of its equity ownership in
Gartner. The transaction, expected to be completed in the first half of 1999, is
to be structured as a tax-free distribution of Gartner stock to IMS Health
shareholders. The transaction is subject to receipt of a favorable ruling from
the IRS, final approval by the Company's and Gartner Boards of Directors, and
approval by Gartner shareholders.

     The Company owns approximately 47 million shares of Gartner. Prior to the
spin-off, 40.1 million of these shares will be exchanged for new Class B Common
Stock of Gartner. The Class B Stock will be entitled to elect 80% of Gartner's
Board of Directors, but will otherwise be identical to existing Class A Common
Stock. The exchange will be part of a Gartner recapitalization and requires
approval by Gartner shareholders. The Class B shares will be distributed to the
Company's shareholders in a tax-free distribution, subject to receipt of a
favorable tax ruling from the Internal Revenue Service with respect to the
distribution. The Company intends to monetize its remaining position in Gartner,
6.9 million shares of Class A Common Stock and warrants to purchase a further
600,000 shares, during the twelve months following the spin-off.

     Separately, Gartner announced that, subject to approval by the IRS of the
tax-free treatment of the distribution, it intends to declare a special one-time
cash dividend of $300,000 to its shareholders of record immediately prior to the
spin-off. The Gartner Board of Directors intends to authorize a $300,000 open
market share repurchase program for up to 20% of its stock commencing
immediately after the spin-off. If completed as currently contemplated the
Company anticipates receiving $200-$300 million after-tax cash proceeds from the
monetization of the stock and warrants and the Gartner dividend.

     The Company has been informed by the Dun & Bradstreet Corporation ("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 is made and the IRS prevails would be approximately $425,000 for
taxes and accrued interest net of tax benefit. Under the terms of the
Distribution Agreement dated October 28, 1996 among D&B, Cognizant and ACNielsen
Corporation (the "1996 Distribution Agreement"), the Company is liable to pay
half of such taxes and interest owed 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 in connection with the Distribution dated June 30,
1998 between Cognizant and the Company. The Company estimates that its current
share of the liability were the IRS to prevail would be approximately $135,000.
(See Note 12. to the Consolidated Financial Statements).

     The Company's existing 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
cash requirements including dividends, acquisitions, stock repurchase programs
and the other contingencies noted above.

YEAR 2000

     Many existing computer systems and software applications use two digits,
rather than four, to record years, e.g., "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".

     The Company began to address the Y2K issue in 1996, when it began to assess
the impact on its operations. In 1997, the Company created a Y2K 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 Y2K program. The Company has
identified its Y2K areas of focus as systems and software for the creation and
delivery of its products and systems and software for its internal
administrative operations.

     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. Coding and
testing involves code changes, using conversion rules and criteria and unit
testing, and verifying and documenting the results of the conversion. Testing
and implementation includes system tests 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
communicated throughout the Company and is being utilized 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 


                                                                               9

Y2K 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. The following is a status
report of each location as of December 31, 1998:

  --------------------------------------------------------------

     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 compliant (such software is excluded from the tables above). In
addition, the Company has decided to replace certain non-compliant software. It
is imperative that these replacement projects be completed and deployed on
schedule, as the existing software is not undergoing Y2K renovation. These
projects are on track to be completed and deployed by the fourth quarter of 1999
and continue to be under close scrutiny by the task force. The Erisco systems
are 99% compliant as of December 31, 1998.

     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 system 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. The
following table represents a status report of each geographic region as of
December 31, 1998:

     These numbers exclude end-user desktop applications such as spreadsheets,
macros, etc. The Company's Y2K project incorporates administrative operations
systems and software such as accounts receivable, payroll, accounts payable and
the general ledger systems. These systems are expected to be 99% compliant by
the end of the first quarter of 1999.

     The Company has also 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
December 31, 1998, audits occurred in the United States, England and Germany,
with follow up audits scheduled for early 1999. An audit of Japan is also
planned for the first quarter of 1999. The Company performs audits on the local
country conversions with the assistance of CTS. Local office audits have been
performed in North America and Europe with South America planned for early 1999.

     The Company relies on over 16,000 suppliers of electronic data and has been
proactive in working with these suppliers to determine their Y2K readiness and
ability to maintain data flow continuity. A program consisting of seminars,
visits, mailings and telephone calls continues to be administered so the Company
can track status and assess risk associated with Y2K readiness for key data
suppliers.

     Considerable risk to some data sources currently exists, especially for
hospital information as their priority relates to patient care. In some
instances, IMS Health receives data from governments and continued receipt of
their data will be a function of their readiness. Based on information from data
sources to date, it appears that the Y2K readiness 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 the use of
a detailed questionnaire regarding Y2K conversion plans in order to verify and
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 will be pursued when
the risk assessment determines the data source to have a high risk of impacting
the Company's ability to deliver products. Ultimately, the risk for our
customers will be the completeness and quality of the data, but the Company
believes it is a short-term issue and is working to minimize the effect on its
data and customers.

     Throughout 1999 the Company's Y2K efforts will focus on (i) the testing the
critical components of the Company's systems; (ii) the continued assessment of
supplier and customer readiness to address the Y2K conversion and; (iii)
finalizing contingency plans to address unanticipated issues.

     External and internal costs of addressing the Y2K issue are expensed as
incurred. It is currently estimated that the aggregate cost of the Company's Y2K
program will be approximately $75,000. Through December 31, 1998 the Company has
incurred $54,741 of which $44,922 was incurred in 1998. The Company expects to
incur between $20,000 to $25,000 in 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 Y2K issue and the dates which the Company
currently expects to complete Y2K 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 Y2K issue. The Company's plans are
dependent on the continuous operation of industries out of the Company's direct
control such as utilities, transportation, etc.

     The above expectations are subject to uncertainties. For example, if the
Company is unsuccessful in identifying or fixing all Y2K problems in its
critical operations, or is affected 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.

MARKET RISK

     The Company's primary market risks are the impact of foreign exchange
fluctuations on non-dollar-denominated revenue and price fluctuations on equity
securities.

     In the normal course of business, the Company employs established practices
and procedures to manage its exposure to fluctuations in the value of foreign
currencies using a variety of financial instruments.

     The Company's objective in managing the exposure to foreign currency
fluctuations is to reduce earnings and cash flow volatility associated with
foreign exchange rate changes 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 committed foreign currency revenues and non-functional currency
assets and liabilities. The principal currencies hedged are the Japanese yen,
the Euro and the Swiss franc. By policy, the Company maintains hedge coverage
between minimum and maximum percentages of its anticipated foreign exchange
exposures over the next year. The gains and losses on these hedges offset
changes in the value of the related exposures.

     It is the Company's policy to enter into foreign currency transactions only
to the extent necessary to meet its objectives as stated above. The Company does
not enter into foreign currency transactions for investment or speculative
purposes.

     The fair value of the Company's hedging instruments are subject to change
as a result of potential changes in foreign exchange rates. The potential loss
in fair value for foreign exchange rate-sensitive instruments, all of which were
forward exchange contracts, based on a hypothetical 10% decrease in the value of
the U.S. dollar or, in the case of non-dollar-related instruments, the currency
being purchased, was $11,977 at December 31, 1998. The estimated fair values of
the foreign exchange risk management contracts were determined based on quoted
market prices.

     The Company also invests in equity securities and is subject to equity
price risk. These investments are classified as available for sale and
consequently, carried at fair value, with unrealized gains and losses, net of
income taxes, reported as a component of shareholders' equity. The Company does
not hedge this market risk exposure. A 10% decline in the market price of these
equity securities would cause the fair value of the securities to decrease by
$3,768 at December 31, 1998.

EURO CONVERSION

     On January 1, 1999, 11 member countries of the European Union established
fixed conversion 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 has prepared for the introduction of the Euro, including the
conversion of information technology systems, recalculating currency risk,
recalibrating derivatives and other financial instruments, strategies concerning
continuity of contracts, and impacts on the processes for preparing taxation and
accounting records. Although the Euro may affect some companies' pricing
policies, differences in IMS' national market size, data collection requirements
and specific product specifications required due to the diverse market
information needs in the healthcare markets of Europe are expected to minimize
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 


                                                                              11

number of risks and uncertainties that could cause the 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 affected systems in a timely manner and the actions of governmental
agencies or other third parties with respect to Euro currency issues.

FORWARD-LOOKING STATEMENTS

      This 1998 Annual Report to Shareholders, as well as information included
in oral statements or other written statements made or to be made by IMS Health,
contain statements which, in the opinion of IMS Health, may constitute
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995 (the "Litigation Reform Act"). These statements
appear in a number of places in this annual report and include, but are not
limited to, all statements relating to plans for future growth and other
business development activities as well as capital expenditures, financing
sources, dividends and the effects of regulation and competition, the terms of
the Distribution Y2K readiness and all other statements regarding the intent,
plans, beliefs or expectations of IMS Health or its directors or officers.
Stockholders are cautioned that such forward-looking statements are not
assurances of future performance or events and involve risks and uncertainties
that could cause actual results and developments to differ materially from those
covered in such forward-looking statements. These risks and uncertainties
include, but are not limited to, risks associated with operating on a global
basis, including fluctuations in the value of foreign currencies relative to the
U.S. dollar, and the ability to successfully hedge such risks; to the extent IMS
Health seeks growth through acquisition, the ability to identify, consummate and
integrate acquisitions on satisfactory terms; the ability to develop new or
advanced technologies and systems for their businesses on a cost-effective
basis; the ability to successfully achieve estimated effective tax rates and
corporate overhead levels; competition, particularly in the markets for
pharmaceutical information; regulatory and legislative initiatives, particularly
in the area of medical privacy; the ability to timely and cost-effectively
resolve any problems associated with the Y2K issue; the ability to obtain future
financing on satisfactory terms; deterioration in economic conditions,
particularly in the pharmaceutical, healthcare, or other industries in which
customers operate; conditions in the securities markets which may effect the
value or liquidity of portfolio investments and management's estimates of lives
of assets, recoverability of assets, fair market value, stimates and liabilities
and accrued income tax benefits and liabilities. Consequently, all the
forward-looking statements contained in this annual report are qualified by the
information contained herein, including, but not limited to, the information
contained under this heading the consolidated financial statements and notes
thereto and by the material set forth under the headings "Business" and
"Factors" that May Affect Future Results, in the Annual Report on Form 10-K for
the year ended December 31, 1998. IMS Health is under no obligation to publicly
release any revision to any forward-looking statement contained or incorporated
herein to reflect any future events or occurrences.

RECENTLY ISSUED ACCOUNTING STANDARDS

     During 1998, various new accounting pronouncements were issued which may
impact the Company's financial statements. (See Note 2. to the Consolidated
Financial Statements).

DIVIDENDS

     The payment and level of cash dividends by the Company are subject to the
discretion of the board of directors of the Company. Although the Company has
declared and anticipates that it will declare quarterly dividends in the range
of 6% to 10% of net earnings, dividend decisions will be based on, and affected
by, a number of factors; including the operating results and financial
requirements of the Company. The Company's Board of Directors approved a first
quarter dividend increase of 33%, to a quarterly rate of $0.02 per post-split
share, or $0.08 per share annually. This follows the January 1999 2-for-1 stock
split.

IMS HEALTH COMMON STOCK INFORMATION

     The Company's common stock is listed on the NYSE (symbol "RX"). The number
of shareholders of record and shares outstanding on December 31, 1998 were
10,084 and 318,741,700, respectively. The high and low closing stock price per
share during 1998 was $38 and $26 3/8, respectively. Approximately 70% of the
Company's shares were held by institutions.

     All share and per-share amounts have been restated to give effect to the
2-for-1 stock split approved by the Company's Board of Directors on December 15,
1998 and distributed to shareholders on January 15, 1999 (See Note 2. to the
Consolidated Financial Statements).

To the Shareholders of IMS Health Incorporated:

     Management is responsible for the preparation of the consolidated financial
statements and related information that are presented in this report. The
consolidated financial statements, which include amounts based on management's
estimates and judgments, have been prepared in conformity with generally
accepted accounting principles. Other financial information in the report to
shareholders is consistent with that in the consolidated financial statements.

     The Company maintains accounting and internal control systems to provide
reasonable assurance at reasonable cost that assets are safeguarded against loss
from unauthorized use or disposition, and that the financial records are
reliable for preparing financial statements and maintaining accountability for
assets. These systems are augmented by written policies, an organizational
structure providing division of responsibilities, careful selection and training
of qualified personnel and a program of internal audits.

     The Company engaged PricewaterhouseCoopers LLP, independent accountants, to
audit and render an opinion on the consolidated financial statements in
accordance with generally accepted auditing standards. These standards include
an assessment of the systems of internal controls and tests of transactions to
the extent considered necessary by them to support their opinion.

     The Board of Directors, through its Audit Committee consisting solely of
outside directors of the Company, meets periodically with management, internal
auditors and our independent accountants to ensure that each is meeting its
responsibilities and to discuss matters concerning internal controls and
financial reporting. PricewaterhouseCoopers and the internal auditors each have
full and free access to the Audit Committee.

REPORT OF INDEPENDENT

- - --------------------------------------------------------------------------------
To the Board of Directors and Shareholders of IMS Health Incorporated:

     In our opinion, the accompanying consolidated statements of financial
position and the related consolidated statements of income, shareholders' equity
and cash flows present fairly, in all material respects, the financial position
of IMS Health Incorporated ("accounting successor to Cognizant Corporation") and
its subsidiaries at December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the years in the three year period
ended December 31, 1998, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

IMS HEALTH INCORPORATED
(ACCOUNTING SUCCESSOR TO COGNIZANT)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Dollar amounts in thousands, except per share data
- - --------------------------------------------------------------------------------

Note 1. Basis of Presentation

     The financial statements and notes relate to IMS Health Incorporated ("IMS
Health" or the "Company"). The Common Stock of IMS Health was distributed by
Cognizant Corporation ("Cognizant") to its shareholders on June 30, 1998.
Simultaneously with the distribution (the "Distribution"), Cognizant changed its
name to Nielsen Media Research, Inc. ("Nielsen Media Research"). Notwithstanding
the legal form of the Distribution, whereby Cognizant spun off IMS Health, for
accounting purposes the transaction is accounted for as if Cognizant spun off
Nielsen Media Research and IMS Health has been deemed the "accounting successor"
to Cognizant. The separation created IMS Health as the global provider of
information solutions to the pharmaceutical and healthcare industries, and
established an independent Nielsen Media Research. IMS Health consists of the
market information, sales management, and decision support services business for
the pharmaceutical and healthcare industries conducted by IMS Health and various
subsidiaries ("IMS"), IMS Health Strategic Technologies Inc. ("Strategic
Technologies"), ERISCO Managed Care Technologies, Inc. ("Erisco"), Enterprise
Associates, Inc. ("Enterprises"), a 61.7% interest in Cognizant Technology
Solutions Corporation ("CTS") and SSJ K.K. ("Super Systems Japan"). The Company
also has an equity investment in Gartner Group, Inc. ("Gartner").

     Cognizant received a favorable ruling from the Internal Revenue Service
("IRS") with respect to the tax-free treatment of the Distribution in May 1998.
Cognizant's Board of Directors on June 15, 1998 approved the final plan, terms
and conditions relating to the separation of the Company including distribution,
tax allocation, employee benefits and other agreements and authorized management
to execute the plan of distribution. The Board of Directors declared a dividend
to shareholders of record as of the close of business on June 25, 1998
consisting of one share of IMS Health Common Stock for each share of Cognizant
Common Stock. The Distribution was effective June 30, 1998.

     In connection with the Distribution, Cognizant borrowed $300,000 on June
24, 1998, which was used to repay existing intercompany liabilities. This debt
remained the obligation of Nielsen Media Research following the Distribution. In
connection with the Distribution, Cognizant contributed to IMS Health all cash
in Cognizant's accounts other than (i) cash required by Cognizant (renamed
Nielsen Media Research) to satisfy certain specified obligations and (ii) such
additional cash as was necessary for the net borrowings of Cognizant (renamed
Nielsen Media Research) to equal $300,000 as of the Distribution.

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

     Pursuant to Accounting Principles Board ("APB") Opinion No. 30, "Reporting
the Results of Operations--Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions," the consolidated financial statements of the Company have been
reclassified to reflect Nielsen Media Research as discontinued operations for
periods up to and including June 30, 1998 and reflect the Distribution which
occurred on June 30, 1998.

     Summarized data for discontinued operations is as follows.

Note 2. Summary of Significant
        Accounting Policies

Consolidation. The consolidated financial statements of the Company include the
accounts of the Company and its subsidiaries after elimination of all material
intercompany accounts and transactions.


                                                                              19
<PAGE>

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Dollar amounts in thousands, except per share data
- - --------------------------------------------------------------------------------


Investments in companies over which the Company has significant influence but
not a controlling interest are accounted for under the equity method of
accounting. The Company recognizes in the income statement any gains or losses
related to the sale or issuance of stock by a consolidated subsidiary or a
company accounted for under the equity basis. (See Note 3. to the Consolidated
Financial Statements).

     The financial statements of the IMS segment reflect a fiscal year ending
November 30 to facilitate timely reporting of the Company's financial results.
(See Note 19. to the Consolidated Financial Statements).

Cash Equivalents. The Company considers all highly liquid investments with a
maturity of 90 days or less at the time of purchase to be cash equivalents.

Securities and Other Investments. Marketable securities, principally consisting
of equity securities, are classified as available-for-sale. Such securities are
carried at fair value, with the unrealized gains and losses, net of income
taxes, reported as a component of shareholders' equity. Any gains or losses from
the sale of these securities are recognized using the specific identification
method. (See Note 8. to the Consolidated Financial Statements).

Property, Plant and Equipment. Buildings and machinery and equipment are
depreciated over their estimated useful lives using principally the
straight-line method. Leasehold improvements are amortized on a straight-line
basis over the shorter of the term of the lease or the estimated useful life of
the improvement.

Computer Software. Direct costs incurred in the development of computer software
are capitalized in accordance with Statement of Financial Accounting Standards
("SFAS") No. 86, "Accounting for the Costs of Computer Software to be Sold,
Leased, or Otherwise Marketed". Research and Development costs incurred to
establish technological feasibility of a computer software product are expensed
in the periods in which they are incurred. Capitalization ceases and
amortization starts when the product is available for general release to
customers. Computer software costs are being amortized, on a product by product
basis, for three to five years. Annual amortization is the greater of the amount
computed using (a) the ratio that gross revenues for a product bear to the total
of current and anticipated future gross revenues for that product, or (b) the
straight-line method over the remaining estimated economic life of the product.
At each balance sheet date, the Company reviews the recoverability of the
unamortized capitalized costs of computer software products by comparing the
carrying value of computer software with its estimated net realizable value. The
Company recognizes any impairment losses on capitalized software as a result of
its review.

Goodwill. Goodwill represents the excess purchase price over the fair value of
identifiable net assets of businesses acquired and is amortized on a
straight-line basis over five to forty years. At each balance sheet date, the
Company reviews the recoverability of goodwill, not identified with impaired
long-lived assets, based on estimated undiscounted future cash flow from
operating activities compared with the carrying value of goodwill and recognizes
any impairment on the basis of such comparison. The recognition and measurement
of goodwill impairment is assessed at the business unit level.

Other Long-Lived Assets. In accordance with the provisions of SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of", the Company reviews long-lived assets and certain identifiable
intangibles held and used for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. In general, this statement requires recognition of an impairment
loss when the sum of undiscounted expected future cash flow is less than the
carrying amount of such assets. Accordingly, the Company recognizes impairment
losses on long-lived assets as a result of its review. The measurement for such
impairment loss is then based on the fair value of the asset. (See Note 7. to
the Consolidated Financial Statements).

Revenue Recognition. The Company generally recognizes revenue as earned, which
is over the contract period or as the information is delivered or related
services are performed. Amounts billed for service and subscriptions are
credited to deferred revenues and reflected in operating revenue over the
subscription term, which is generally one year. Software license revenue is
recognized upon delivery of the software, when persuasive evidence of an
arrangement exists, the related fees are fixed or determinable and collection of
fees is probable. Revenue from post-contract customer support (maintenance) is
recognized on a straight-line basis over the term of the contract.

Foreign Currency Translation. The Company has significant investments in
non-U.S. countries. Therefore, changes in the value of foreign currencies affect
the Company's consolidated financial statements when translated into U.S.
dollars.

     For all operations outside the United States where the Company has
designated the local currency as the functional currency, assets and liabilities
are translated using end-of-period exchange rates; revenues and expenses are
translated using average rates of exchange. For these countries, 


20
<PAGE>


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Dollar amounts in thousands, except per share data
- - --------------------------------------------------------------------------------


currency translation adjustments are accumulated in a separate component of
shareholders' equity whereas realized transaction gains and losses are
recognized in other expense net. For operations in countries that are considered
to be highly inflationary or where the U.S. dollar is designated as the
functional currency, monetary assets and liabilities are translated using
end-of-period exchange rates, whereas non-monetary accounts are translated using
historical exchange rates, and all translation and transaction adjustments are
recognized in other expense net.

Income Taxes. Prior to the Distribution, the Company was included in the Federal
and certain state and non-U.S. income tax returns of Cognizant. Income taxes are
provided using the asset and liability method in accordance with SFAS No. 109.
Deferred tax assets and liabilities are recognized based on differences between
the book and tax bases of assets and liabilities using presently enacted tax
rates. The provision for income taxes is the sum of the amount of income tax
paid or payable for the year as determined by applying the provisions of enacted
tax laws to taxable income for that year and the net changes during the year in
the Company's deferred tax assets and liabilities.

Estimates. The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenues
and expenses and the disclosure of contingent assets and liabilities. Actual
results could differ from those estimates. Estimates are used for, but not
limited to, the accounting for: allowance for uncollectible accounts receivable,
depreciation and amortization, capitalized software costs, employee benefit
plans, taxes, restructuring reserves, contingencies, in-process research and
development ("IPR&D") and purchase price allocations.

Earnings Per Share. Basic earnings per share are calculated by dividing net
income by weighted average common shares. Diluted earnings per share are
calculated by dividing net income by dilutive potential common shares. Dilutive
potential common shares are calculated in accordance with the treasury stock
method, which assumes that proceeds from the exercise of all options are used to
repurchase common stock at market value. The amount of shares remaining after
the proceeds are exhausted represent the potentially dilutive effect of the
securities. The computation includes the weighted average number of shares of
Cognizant common stock outstanding through the Distribution Date, reflecting the
one-for-one distribution ratio, and the weighted average number of shares of IMS
Health common stock outstanding since the Distribution.

     On December 15, 1998, the Company's Board of Directors authorized a 2-for-1
split of its common stock effective January 15, 1999, in the form of a stock
dividend to shareholders of record on December 29, 1998. All share and per-share
amounts in the accompanying Consolidated Financial Statements and Notes to
Consolidated Financial Statements have been restated to give effect to the stock
split.

Concentrations of Credit Risk. IMS Health maintains accounts receivable balances
($324,219 and $251,623 at December 31, 1998 and 1997, respectively), principally
from customers in the pharmaceutical industry.

Reclassifications. Certain prior-year amounts have been reclassified to conform
with the 1998 presentation.

Recently Issued Accounting Standards. In March 1998, the American Institute of
Certified Public Accountants ("AICPA") issued 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 and when capitalization of such
costs should commence. SOP 98-1 applies to costs incurred after adoption,
including costs for software projects that are in progress at the time of the
adoption. The Company has evaluated the impact of this SOP on its financial
position and results of operations and will implement SOP 98-1 for fiscal years
beginning after December 15, 1998. The adoption of this pronouncement will 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 years
beginning after December 15, 1998. The adoption of this pronouncement will not
have a material effect on the Company's financial statements.

     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities". SFAS
No. 133 is effective for all fiscal quarters for all fiscal years beginning
after June 15, 1999 (January 1, 2000 for the Company). SFAS No. 133 requires
that all derivative instruments be recorded on the balance sheet at their fair
value. Changes in the fair value of derivatives are recorded each period in
current earnings or other comprehensive income, depending on whether a
derivative is designated as part of a hedge transaction and, if it is, the type
of hedge transaction. For fair-value hedge transactions in which the Company is
hedging changes in an asset's, liability's, or firm commitment's fair value,
changes in the fair value of the derivative instrument will generally be offset
in the income statement by changes in the hedged item's fair value. For
cash-flow hedge transactions, in which the Company is 


                                                                              21

hedging the variability of cash flows related to a variable-rate asset,
liability, or a forecasted transaction, changes in the fair value of the
derivative instrument will be reported in other comprehensive income. The gains
and losses on the derivative instrument that are reported in other comprehensive
income will be reclassified as earnings in the periods in which earnings are
impacted by the variability of the cash flows of the hedged item. The
ineffective portion of all hedges will be recognized in current period earnings.
Management is currently evaluating the effects of this change on the Company's
financial statements.

================================================================================

Note 3. Investment in Gartner

     In the third quarter of 1997, the Company's voting interest in Gartner fell
below 50%, principally as a result of the exercise of Gartner employee stock
options and employee stock purchases. Accordingly, effective January 1, 1997,
the Company deconsolidated Gartner in that year and is now accounting for its
ownership interest on the equity basis.

     In 1998, proceeds from the issuance of shares to Gartner employees,
including associated tax benefits, increased Gartner's equity by $43,654 and
reduced the Company's ownership interest by less than 1% to approximately 47% at
September 30, 1998. Accordingly, the Company recognized a pre-tax unrealized
gain on Gartner stock of $14,838 corresponding to the net increase in the value
of its underlying investment in Gartner. As a result of the proposed tax-free
spin-off of Gartner, the Company has not recognized gains in accordance with
Staff Accounting Bulletin 51 ("SAB 51") for the fourth quarter of 1998.

     Selected financial information regarding the results of operations and
financial position of Gartner is summarized below:

Note 4. Dispositions

     During 1998, the Company realized a net $46,118 pre-tax gain on the sale of
certain of its investments including Aspect Development Inc., which is part of
Enterprises' portfolio and the sale of stock holdings in CTS. (See Note 6. to
the Consolidated Financial Statements). These sales generated cash proceeds of
$78,883.

     During 1997, the Company realized a $39,336 pre-tax gain on the sale of its
investment in WEFA Group, Inc. and a portion of its investment in TSI
International, Inc. and Aspect Development, Inc. These investments, which were
part of Enterprises' portfolio, generated cash proceeds of $43,601.

     Additionally, in the third quarter of 1997, the Company sold its wholly
owned subsidiary Pilot Software Inc. and realized a non-cash pre-tax loss of
$29,945.

================================================================================

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. For financial reporting purposes, 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 interest (85%) in the partnership.
The third-parties' investments in this partnership are reflected as a minority
interest.

================================================================================

Note 6. Public Offering of a Subsidiary

     CTS effected an initial public offering (the "CTS IPO") of 2,917,000 shares
of Class A Common Stock, par value $0.01 per share, of CTS (3,354,550 including
the underwriters' over-allotment option granted by Cognizant) on June 19, 1998.
Of such shares, 2,500,000 were offered by CTS and 417,000 shares were offered by
Cognizant, the accounting predecessor to IMS Health. Of the total proceeds, CTS
used approximately $6.5 million to repay intercompany debt owed to Cognizant.
Cognizant's interest in CTS was transferred to the Company in the Distribution.
The transaction (other than the over-allotment option) closed on June 24, 1998
and resulted in a gain of $12,777, which is a SAB 51 gain. The underwriters
over-allotment option was exercised during the third quarter. The Company
recognized a gain from this sale. The Company's

ownership interest is 61.7% at December 31, 1998 and accordingly, the Company
consolidates CTS's results within its financial statements. Any minority
interest is captured on the Statement of Financial Position in the minority
interest line and on the Consolidated Statements of Income in the Other
Expense-Net line. CTS's Class A Common Stock is listed on the NASDAQ National
Market under the symbol "CTSH".

Note 7. Acquisitions and Joint Venture

Walsh Acquisition

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

     Under the terms of Walsh acquisition agreement, Walsh shareholders received
 .6082 (on a pre-split basis the ratio is .3041) shares of Cognizant common stock
per Walsh per share or based on a Cognizant share price of $25.896,
consideration of approximately $167,148 (on a pre-split basis a Cognizant share
price of $51.792). Walsh had 10,612,628 shares outstanding. Cognizant issued
6,454,600 shares from treasury stock to consummate the Walsh acquisition. The
direct acquisition and integration costs consist of severance of $4,876, lease
terminations of $2,569, and other direct acquisition and integration costs of
$9,634. These direct acquisition and integration costs were incurred as a direct
result of the acquisition and the formal 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). To date
incurred acquisition and integration costs are within original estimates.
Approximately $156,557 is 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 $75,292 of common stock, $5,415 of stock
options and $22,584 of accrued acquisition and integration costs.

     Under the terms of PMSI acquisition agreement, PMSI received 2,395,926
shares of IMS Health common stock issued from treasury stock, consideration of
approximately $75,292. The acquisition and integration costs consist of
severance of $3,794, lease terminations of $1,623, contract cancellation of
$10,935, and other direct acquisition and integration costs of $6,232. These
direct acquisitions and integration costs are incremental to other costs and
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). Acquisition and integration costs incurred to date are
within original estimates. Approximately $115,275 is 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.

Joint Venture

     On September 1, 1998, the Company formed a joint venture with IHA Institut
fur Marktanalysen AG ("IHA"). The Company and IHA each contributed all of their
Swiss pharmaceutical research assets to the venture and each own 50% of the
venture. The Company contributed assets of $54 and cash of $11,014. The $12,027
excess of the investment over the value of the Company's share of the net assets
has been recorded as goodwill, which is being amortized on a straight line basis
over 20 years. The Company has accounted for its ownership interest in the
venture under the equity basis.

Purchase Price Allocation

     In connection with both the Walsh and PMSI acquisitions, the Company made
allocations of the purchase price to acquired 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.

     The Securities and Exchange Commission (the "SEC") recently issued revised
guidance with respect to allocations of IPR&D projects in connection with an
acquisition. In accordance with this guidance, 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 will be used. 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 


                                                                              23

by an independent appraisal firm. The allocation is summarized below:

                                          WALSH           PMSI           TOTAL

Total Purchase Price                   $193,748       $103,291        $297,039
- - -------------------------------------------------------------------------------

     The excess of the purchase price over the fair value of the net tangible
and identifiable intangible assets acquired has been recorded as goodwill, which
is being amortized on a straight-line basis over a period of 15 years.

     At the date of the respective acquisitions, the development of the IPR&D
projects had not yet reached technological feasibility and had no alternative
future uses. Accordingly, these costs were expensed as of the respective
acquisition dates.

     In the aggregate, the impact of both the Walsh and PMSI acquisitions on the
results of operations, other than the one-time charges and the IPR&D write-offs,
had they occurred on January 1, 1998 or 1997 would be immaterial.

     In connection with the PMSI acquisition, the Company commenced an
evaluation of its existing IMS Health product offerings. Based on this strategic
assessment, the Company decided to abandon 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 as a one time acquisition charge as a component of
operating income.

Note 9. Financial Instruments

Foreign Exchange Risk Management

     The Company transacts business in virtually every part of the world and is
subject to risks associated with changing foreign exchange rates. The Company's
objective is to reduce earnings and cash flow volatility associated with foreign
exchange rate changes 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 committed and anticipated foreign currency revenues and
non-functional currency assets and liabilities. The Company's policy is to
maintain hedge coverage between minimum and maximum percentages of its
anticipated foreign exchange exposures over the next year. The gains and losses
on these hedges offset changes in the value of the related exposures.

     It is the Company's policy to enter into foreign currency transactions only
to the extent necessary to meet its objectives as stated above. The Company does
not enter into foreign currency transactions for investment or speculative
purposes.

     The Company uses forward contracts and purchased currency options to hedge
committed and anticipated foreign currency denominated revenues, respectively.
The principal currencies hedged are the Japanese yen, the Euro and the Swiss
franc. The Company also uses forward contracts to hedge non-functional currency
assets and liabilities.

     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. At December 31, 1998, the notional amount
hedged of committed foreign revenues was $126,271. At December 31, 1998, the
Company had deferred losses of $1,185 related to foreign currency hedge
transactions. Deferred amounts to be recognized can change with market
conditions and are expected to be substantially offset by changes in the value
of the related hedged transactions. The impact of foreign exchange risk
management activities on operating income in 1998 and 1997 was a net gain of $
9,433 and $15,617, respectively. In addition, at December 31, 1998, the Company
had approximately $75,211 in foreign exchange forward contracts outstanding with
various expiration dates through January 1999 hedging non-functional currency
assets and liabilities. Gains and losses on contracts hedging non-functional
currency assets and liabilities are not deferred and are included in current
income in other income/expense-net.

Fair Value of Financial Instruments

     At December 31, 1998, the Company's financial instruments included cash,
cash equivalents, receivables, accounts payable and foreign exchange risk
management contracts. At December 31, 1998, the fair values of cash, cash
equivalents, receivables and accounts payable approximated carrying values due
to the short-term nature of these instruments. At December 31, 1998, the
notional amounts of the Company's risk management contracts were $201,482 and
all contracts mature in 1999. The estimated fair values of the foreign exchange
risk management contracts were determined based on quoted market prices.

Credit Concentrations

     The Company continually monitors its positions with, and the credit quality
of, the financial institutions which are counterparties to its financial
instruments and does not anticipate non-performance by the counterparties. The
Company would not realize a material loss as of December 31, 1998 in the event
of non-performance by any one counterparty. The Company enters into transactions
only with financial institution counterparties which have a credit rating of A
or better. In addition, the Company limits the amount of credit exposure with
any one institution.

     The Company maintains accounts receivable balances ($324,219 and $251,623
at December 31, 1998 and 1997, respectively), principally from customers in the
pharmaceutical industry. The Company's trade receivables do not represent
significant concentrations of credit risk at December 31, 1998 due to the high
quality of its customers and their dispersion across many geographic areas.


                                                                              25

     The Distribution at June 30, 1998 resulted in a transfer of the allocable
portion of the benefit obligation and plan assets to Nielsen Media Research.
(See Note 1. to the Consolidated Financial Statements). Pension expenses related
to discontinued operations included in the table above were $226, $1,571 and
$2,397 for the years 1998, 1997 and 1996, respectively. Other benefit costs for
discontinued operations were not significant.

     The projected benefit obligation, accumulated benefit obligation, and fair
value of plan assets for the pension plan with accumulated benefit obligations
in excess of plan assets were $35,036, $28,964, and $14,695, respectively, as of
December 31, 1998, and $38,247, $23,522, and $13,415, respectively as of
December 31, 1997.

     Assumed health care costs trend rates have a significant effect on the
amounts reported for the health care plan. A one-percentage-point change in
assumed health care cost trend rates for 1998 would have the following effects:

     Certain employees of the Company in the United States also are eligible to
participate in the Company-sponsored defined contribution plan. The Company's
businesses make a matching contribution of up to 50% of the employee's
contribution based on specified limits of the employee's salary. The Company's
expense related to this plan was $3,713, $4,666 and $4,075 for the years 1998,
1997 and 1996, respectively which includes expenses related to discontinued
operations of $768, $2,021, and $1,797 for the years 1998, 1997, and 1996,
respectively.

Note 11. Employee Stock Plans

     The Company has an Employees Stock Incentive Plan which provides for the
grant of stock options and restricted stock to eligible employees. In addition
it provides an opportunity for the purchase of stock options with a prepayment
equal to ten percent of the exercise price, with the remaining payment due when
the options are exercised. All options have a life of ten years, vest
proportionally over three to six years and have an exercise price equal to the
fair market value of the common stock on the grant date.

     The Company adopted an Employee Stock Purchase Plan in 1998 which allows
eligible employees to purchase a limited amount of common stock at the end of
each quarter at a price equal to the lesser of 90% of fair market value on (a)
the first trading day of the quarter, or (b) the last trading day of the
quarter. Fair market value is defined as the average of the high and low prices
of the shares on the relevant day.

     Gartner has several stock option and stock purchase plans. The exercise
price of options granted under the plans is equal to the fair market value at
the date of grant of Gartner stock. Options outstanding and exercisable were
14,560,757 and 5,774,615, respectively, at December 31, 1998, at prices ranging
from $0.63 to $35.68 per share.

     In July 1997, CTS adopted a Key Employees Stock Option Plan which provides
for the grant of stock options to eligible employees. Options granted under this
plan may not be granted at an exercise price less than fair market value of the
underlying shares on the date of grant. All options have a life of ten years,
vest proportionally over four years and have an exercise price equal to the fair
market value of the common stock on the grant date. At December 31, 1998,
586,776 options were outstanding at a weighted average exercise price of $5.40
per share. Of this amount, 89,628 were exercisable at a price of $3.85.

     In December 1997, CTS adopted a Non-Employee Directors' Stock Option Plan
which provides for the grant of stock options to eligible directors. Options
granted under this plan may not be granted at an exercise price less than fair
market value of the underlying shares on the date of grant. All options have a
life of ten years, vest proportionally over two years and have an exercise price
equal to the fair market value of the common stock on the grant date. At
December 31, 1998, 49,500 options were outstanding at a weighted average
exercise price of $9.76 per share. Of this amount, 10,250 were exercisable at
prices ranging from $9.08 to $10.00 per share.

     In March 1998, CTS granted non-qualified stock options to purchase an
aggregate of 48,750 shares to CTS's Chairman and Chief Executive Officer at an
exercise price of $6.92 per share. At December 31, 1998, 12,187 were
exercisable.

SFAS No. 123, "Accounting for Stock-Based Compensation" requires that companies
with stock-based compensation plans either recognize compensation expense based
on the fair value of options granted or continue to apply the existing
accounting rules and disclose pro forma net income and earnings per share
assuming the fair value method had been applied. The Company has chosen to
continue applying APB Opinion No. 25 and related interpretations in accounting
for its plans. Accordingly, no significant compensation cost has been recognized
for the fixed stock option plans. Had compensation cost for the Company's
stock-based compensation plans been determined based on the fair value at the
grant dates for awards under those plans, consistent with the method of SFAS No.
123, the Company's net income and earnings per share would have been reduced to
the pro forma amounts indicated below:

Note: The pro forma disclosures shown above are not representative of the
effects on net income and earnings per share in future years.

     The fair value of the Company's stock options used to compute pro forma net
income and earnings per share disclosures is the estimated present value at
grant date using the Black-Scholes option pricing model. The following
weighted-average assumptions were used for 1998, 1997 and 1996: dividend yield
of 0.3%; expected volatility of 25%; a risk-free interest rate of 5.1%; and an
expected term of 3.5 years. The weighted average fair value of the Company's
stock options granted in 1998, 1997 and 1996 are $7.92, $6.56 and $4.88,
respectively.

     The fair value of Gartner stock options used to compute the Company's pro
forma net income and earnings per share disclosures was computed in the same
manner as the Company's with the following weighted-average assumptions for
1998, 1997 and 1996: dividend yield of 0%; expected volatility of 38%; a
risk-free interest rate of 5.4%; and an expected term of 3.5 years. The weighted
average fair value of Gartner stock options granted in 1998, 1997 and 1996 are
$11.55, $10.12 and $11.80, respectively.

     Immediately following the 1996 Distribution, outstanding awards under the
D&B Key Employees Stock Option Plans held by Cognizant employees were canceled
and replaced by substitute awards under Cognizant's Key Employees Stock
Incentive Plan. The substitute awards had the same ratio of the exercise price
per option to the market value per share, the same aggregate difference between
market value and exercise price and the same vesting provisions, option periods
and other terms and conditions as the options they replaced.

     Immediately following the Distribution, outstanding awards under
Cognizant's Key Employees Stock Incentive Plan and other option plans were
cancelled and replaced by substitute awards under various IMS Health option
plans. The formula to determine the number of replacement options was the
average fair market value of Cognizant shares before the Distribution divided by
the average fair market value of IMS Health shares after the Distribution.

     At December 31, 1998, outstanding options for IMS Health common stock held
by Company employees, including the replacement awards mentioned above, totaled
28,859,996, of which 5,402,436 had vested and were exercisable. The option
prices range from $3.69 to $34.25 per share and are exercisable over periods
ending no later than 2008. At December 31, 1997, outstanding options for
Cognizant common stock held by Company employees totaled 43,844,780, of which
8,772,362 had vested and were exercisable. The option prices ranged from $11.50
to $22.24 per share.

Note 12. Income Taxes

     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 is made and the IRS prevails
would be approximately $425,000 for taxes and accrued interest net of tax
benefit. Under the terms of the Distribution Agreement dated October 28, 1996
among D&B, Cognizant and ACNielsen Corporation (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. The Company estimates that its share of the
liability were the IRS to prevail would be approximately $135,000. This
liability has been included in other liabilities.

     The Company has accrued its anticipated share of the probable liability to
D&B under the 1996 Distribution Agreement. Accordingly, management does not
believe that this matter will have a material adverse effect on the Company's
consolidated financial position or operating results when it is resolved in a
future period. However, should the IRS issue an assessment notice, payment of
the Company's share could have a material adverse effect on cash flows in the
period in which it is made. However, the Company believes that is 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.

     To consolidate certain of its international operations, in 1998 the Company
engaged in certain non-U.S. reorganizations which gave rise to tax deductible
non-U.S. intangible assets.

     The 1998 net deferred tax asset consists of a current deferred tax asset of
$32,749, included in Other Current Assets, offset by a non-current deferred tax
liability of $30,322. (See Notes 2., 5. and 16. to the Consolidated Financial
Statements).

     The Company has established a valuation allowance attributable to deferred
tax assets in certain U.S. state and non-U.S. tax jurisdictions where, based on
available evidence, it is more likely than not that such assets will not be
realized.

     Undistributed earnings of non-U.S. subsidiaries aggregated approximately
$534,930 at December 31, 1998. Deferred tax liabilities have not been recognized
for these undistributed earnings because it is the Company's intention to
indefinitely reinvest such undistributed earnings outside the United States. If
such earnings are repatriated in the future, or are no longer deemed to be
indefinitely reinvested, applicable taxes will be provided for on such amounts.
It is not currently practicable to determine the amount of applicable taxes.

Note 13. Commitments

     Certain of the Company's operations are conducted from leased facilities,
which are under operating leases. Rental expense under real estate operating
leases for the years 1998, 1997 and 1996 was $21,868, $19,432, and $28,963,
respectively. The minimum annual rental expense for real estate operating leases
that have remaining noncancelable lease terms in excess of one year, net of
sublease rentals, at December 31, 1998 was: 1999--$22,527; 2000--$21,563;
2001--$20,762; 2002--$17,313; 2003--$15,029 and an aggregate of $31,546
thereafter.

     The Company also leases or participates in leases of certain computer and
other equipment under operating leases. These leases are frequently renegotiated
or otherwise changed as advancements in computer technology produce
opportunities to lower costs and improve performance. Rental expense under
computer and other equipment leases was $17,815, $28,241, and $23,372 for 1998,
1997 and 1996, respectively. At December 31, 1998, the minimum annual rental
expense for computer and other equipment under operating leases that have
remaining noncancelable lease terms in excess of one year was: 1999--$16,778;
2000--$10,859; 2001--$6,435; 2002--$5,320 and 2003--$651.

     The Company has agreements with various third parties to purchase certain
data and telecommunications services, extending beyond one year. At December 31,
1998, the purchases covered by these agreements aggregated: 1999--$76,287;
2000--$26,181 and 2001--$14,389.

Note 14. IMS Health Capital Stock

     Under the Company's Restated Certificate of Incorporation, the Company has
authority to issue 420,000,000 shares with a par value of $.01 per share of
which 400,000,000 represent shares of common stock, 10,000,000 represent shares
of preferred stock and 10,000,000 represent shares of series common stock. The
preferred and series common stock can be issued with varying terms, as
determined by the Board of Directors.

     On June 30, 1998, 335,225,390 shares of the Company's common stock were
distributed to the shareholders of Cognizant. Since the Company has been treated
as the successor entity for accounting purposes, the Company's historical
financial statements reflect the recapitalization of the Company in connection
with the Distribution, including the elimination of treasury shares (which
shares became treasury shares of Nielsen Media Research).

     In connection with the Distribution, the Company entered into a Rights
Agreement designed to protect shareholders of the Company in the event of
unsolicited offers to acquire the Company and the other coercive takeover
tactics which, in the opinion of the Board of Directors, could impair its
ability to represent shareholder interests. Under the Rights Agreement, each
share of the common stock has one-half of one right which trades with the stock
until the right becomes exercisable. Each right entitles the registered holder
to purchase 1/1000 of a share of Series A Junior Participating Preferred Stock,
par value $.0l per share, at a price of $225 per 1/1000 of a share, subject to
adjustment. The rights will generally not be exercisable until a person or group
("Acquiring Person") acquires beneficial ownership of, or commences a tender
offer or exchange offer which would result in such person or group having
beneficial ownership of 15% or more of the outstanding common stock (20% in the
case of certain institutional investors).

     In the event that any person or group becomes an Acquiring Person, each
right will thereafter entitle its holder (other than the Acquiring Person) to
receive, upon exercise, shares of stock having a market value of two times the
exercise price in the form of the Company's common stock or, where appropriate,
the Acquiring Person's common stock. The Company may redeem the rights, which
expire in June 2008, for $0.01 per right, under certain circumstances.

     On October 21, 1997 Cognizant announced that its board of directors had
authorized a systematic stock repurchase program to buy up to 20,000,000 shares
(on a post split basis) of Cognizant's outstanding common stock. As the
"Accounting Successor to Cognizant," the Company purchased the remaining balance
of 18,850,800 shares of the Company's stock (on a post split basis). A portion
of this program was intended to offset option exercises. This program was
completed by the Company on November 17, 1998 at a total cost of $591,331.

     In the fourth quarter, the Board of Directors authorized a stock repurchase
program to buy up to 16,000,000 shares of the Company's outstanding common
stock. A portion of this program is intended to offset option exercises. Through
December 31, 1998, 2,898,800 shares have been acquired at a total cost of
$98,113.

                                                                              31

Note 15. 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 or cash flows when resolved in a future
period. However, in the opinion of management, these matters will not materially
affect the Company's consolidated financial position.

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

Information Resources Litigation

     On July 29, 1996, Information Resources, Inc. ("IRI") filed a complaint in
the United States District Court for the Southern District of New York, naming
as defendants D&B, A.C. Nielsen Company and I.M.S. International Inc. (a
predecessor of IMS Health) (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 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 D&B of shares of
Cognizant and ACNielsen in 1996, D&B, ACNielsen (the parent company of A.C.
Nielsen Company) 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 1996 Distribution Agreement as a condition to the
Distribution, IMS Health and Nielsen Media Research were required to and did
undertake to be jointly and severally liable to D&B and ACNielsen for
Cognizant's obligations under the 1996 Distribution Agreement. In connection
with the Distribution, IMS Health and Nielsen Media Research 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 has agreed
to be fully responsible for any legal fees and expenses incurred during 1998.
Nielsen 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 million.

     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 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. (See Notes 2. and 12. to the Consolidated
Financial Statements).

financial application software products to the Japanese market; Enterprises, the
Company's venture capital unit focused on investments in emerging healthcare
businesses; and Pilot Software Inc. ("Pilot"), which was sold as of July 31,
1997.

Note 18. Subsequent Events (Unaudited)

Elimination of one month Reporting lag in IMS operating entities. As indicated
in Note 2. to the Consolidated Financial Statements, the Company consolidates
its IMS operating units on a one month reporting lag basis. Effective in the
first quarter of the Company's 1999 fiscal year, IMS operating units that
previously reported on a fiscal year ending November 30, changed their reporting
period to eliminate the one month lag to bring these to a fiscal year ending
December 31. This change was made to reflect the results of operations and
financial position of these operating units on a more timely basis and to
increase operating and planning efficiency. The results of these operating units
for the period December 1 through December 31, 1998, will be reflected as an
adjustment to retained earnings in the Company's 1999 first quarter reporting
period ending March 31, 1999. The Company is still evaluating the financial
statement impact of the change.

QUARTERLY FINANCIAL DATA (UNAUDITED)

Dollar amounts in thousands, except per share data

Historical results are restated to reflect Nielsen Media Research as a discontinued operation. (See Note 1. to the Consolidated
Financial Statements). The results of operations and related disclosures as of and for the quarter ended June 30, 1998 and September
30, 1998 have been restated as it relates to the purchase price allocation for the Walsh and PMSI acquisitions. This change was made
to conform with the SEC's refined approach for the measurement of acquired IPR&D, Core Technology/Software and the related
allocation of purchase price. The estimate for the one time charge for the acquired IPR&D projects for the original quarterly
filing(s) upon the acquisitions was $57,000 for Walsh (revised to $52 million quarter 3) and $14,200 for PMSI. These have now been
reduced to $21,900 and $10,900, respectively. The impact of this re-allocation of the purchase price on the income statement, is an
increase to net income of $35,100 for quarter 2 and a decrease in pre-tax income of $2,335 for Quarter 3, on previously reported
amounts for consolidated income. The impact of increased amortization expense related to the intangible assets is not significant.
Net income for the year is increased now by $32,785. (See note 7 to the Consolidated Financial Statement). Additionally, the Company
has retroactively restated all per-share amounts to give effect for the 2:1 stock split (See Note 2. to the Consolidated Financial
Statements). 1997 quarterly results have been restated to reflect the deconsolidation of Gartner. (See Note 3. to the Consolidated
Financial Statements).

     each  member  of the NMR  Group  to,  assign,  transfer  and  convey to the

     member of the NMR Group's  respective  right,  title and interest in and to

     Agreement  shall not  constitute an agreement to assign any  agreement,  in
     whole or in part,  or any rights  thereunder  if the agreement to assign or

Corporation  under this  Agreement with respect to the payment of its portion of
such settlement shall be adjusted as follows:

          (I) if the payment date for the settlement (the "Payment Date") occurs

     (plus interest thereon at the prevailing  three-month treasury rate) in two
     equal installments to be paid on each of the first and second anniversaries
     of the Payment Date; and

          (II) if the Payment Date occurs on or after the second  anniversary of
     the  Distribution   Date  but  prior  to  the  third   anniversary  of  the
     Distribution Date, then (A) the Corporation shall pay 66 2/3% of the amount
     that it would  otherwise be  obligated to pay  hereunder in respect of such
     settlement on the Payment  Date,  (B) IMS HEALTH shall pay the remaining 33
     1/3% of such amount on behalf of the  Corporation  on the Payment  Date and

     SECTION  II.4.  Assumption  and  Satisfaction  of  Liabilities.  Except  as

assumption of any Liabilities hereunder.

     SECTION II.5. Resignations.  (a) Subject to Section 2.5(b), the Corporation

Information  Statement  as the  person  who is to hold such  position  or office
following the Distribution.

     SECTION II.6. Further  Assurances.  In case at any time after the Effective
Time any further  action is  reasonably  necessary or desirable to carry out the
purposes of this Agreement and the Ancillary Agreements,  the proper officers of

hereto  agrees  that no party  hereto  is,  in this  Agreement  or in any  other
agreement or document  contemplated  by this Agreement or otherwise,  making any
representation  or  warranty  whatsoever,  as to title or value of Assets  being

otherwise  expressly  provided  in  the  relevant  Conveyancing  and  Assumption
Instrument,  all Assets either transferred to or retained by the parties, as the
case may be,  shall be "as is,  where is" and that  (subject to Section 2.6) the
party to which  such  Assets  are to be  transferred  hereunder  shall  bear the
economic and legal risk that such party's or any of the  Subsidiaries'  title to
any  such  Assets  shall be  other  than  good  and  marketable  and  free  from
encumbrances.  Similarly,  each party hereto  agrees  that,  except as otherwise
expressly provided in the relevant  Conveyancing and Assumption  Instrument,  no
party hereto is  representing or warranting in any way that the obtaining of any
consents or approvals,  the execution and delivery of any amendatory  agreements
and the making of any filings or  applications  contemplated  by this  Agreement
will  satisfy  the  provisions  of  any  or  all  applicable  agreements  or the
requirements  of any or all applicable  laws or judgments,  it being agreed that
the party to which any Assets are transferred  shall bear the economic and legal
risk

Section 2.8, the  applicable  guarantor or obligor shall continue to be bound as
such and,  unless  not  permitted  by law or the  terms  thereof,  the  relevant
beneficiary  shall  or  shall  cause  one  of  its  Subsidiaries,  as  agent  or
subcontractor  for such guarantor or obligor to pay, perform and discharge fully
all the obligations or other liabilities of such guarantor or obligor thereunder
from and after the date hereof.

     SECTION  II.9.   Witness  Services.   At  all  times  from  and  after  the
Distribution  Date,  each of the  Corporation  and IMS  HEALTH  shall  use their
commercially  reasonable efforts to make available to the other, upon reasonable
written request, its and its Subsidiaries'  officers,  directors,  employees and
agents as  witnesses  to the extent  that (i) such  persons  may  reasonably  be
required in connection  with the  prosecution  or defense of any Action in which
the  requesting  party may from time to time be  involved  and (ii)  there is no
conflict in the Action between the requesting  party and the  Corporation or IMS
HEALTH as  applicable.  A party  providing  witness  services to the other party
under this  Section  shall be entitled  to receive  from the  recipient  of such
services, upon the presentation of invoices therefor, payments for such amounts,
relating to  disbursements  and other  out-of-pocket  expenses  (which  shall be
deemed to exclude  the costs of  salaries  and  benefits  of  employees  who are
witnesses), as may be reasonably incurred in providing such witness services.

     SECTION  II.10.   Certain   Post-Distribution   Transactions.   (a)(i)  The
Corporation  shall  comply and shall cause its  Subsidiaries  to comply with and
otherwise not take action  inconsistent with each  representation  and statement
made to the  Internal  Revenue  Service in  connection  with the  request by the
Corporation for a ruling letter in respect of the Distribution as to certain tax
aspects  of the  Distribution  and (ii) until two years  after the  Distribution
Date,  the  Corporation  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)(i) IMS HEALTH shall comply and shall cause its  Subsidiaries  to comply
with and otherwise not take action  inconsistent  with each  representation  and
statement made to the Internal Revenue Service in connection with the request by
the Corporation for a ruling letter in respect of the Distribution as to certain
tax aspects of the  Distribution and (ii) until two years after the Distribution
Date,  IMS HEALTH 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.

     (c) The  Corporation  agrees  that until two years  after the  Distribution
Date, it will not (i) merge or consolidate  with or into any other  corporation,
(ii)  liquidate  or  partially   liquidate,   (iii)  sell  or  transfer  all  or
substantially  all of its assets (within the meaning of Rev. Proc. 77-37, 1977 -
2 C.B.  568) in a single  transaction  or series of related  transactions,  (iv)
redeem or  otherwise  repurchase  any  Cognizant  Common  Stock  (other  than as
described in Section  4.05(1)(b) of Rev. Proc.  96-30,  1996-1 C.B. 696), or (v)
take any other action or actions which in the aggregate would have the effect of
causing or  permitting  one or more  persons to acquire  directly or  indirectly
stock  representing  a 50 percent or greater  interest  (within  the  meaning of
Section  355(e) of the Code) in the  Corporation,  unless  prior to taking  such
action the  Corporation  has  obtained  (and  provided  to IMS HEALTH) a written
opinion of a law firm  reasonably  acceptable to IMS HEALTH,  or a  supplemental
ruling from the Internal Revenue  Service,  that such action or actions will not
result in (i) the  Distribution  failing to qualify under Section  355(a) of the
Code or (ii) the IMS HEALTH  Common  Shares  failing  to  qualify  as  qualified
property  for  purposes  of Section  355(c)(2)  of the Code by reason of Section
355(e) of the Code.

     (d)  Notwithstanding  anything  to  the  contrary  herein  or  in  the  Tax
Allocation  Agreement,  if  the  Corporation  or IMS  HEALTH  (or  any of  their
respective  Subsidiaries)  fails to  comply  with any of its  obligations  under
Sections 2.10(a), 2.10(b) and 2.10(c) above or takes or fails to take any action
on or after  the  Distribution  Date,  and such  failure  to  comply,  action or
omission  contributes  to a  determination  that (i) the  Distribution  fails to
qualify  under  Section  355(a) of the Code or (ii) the IMS HEALTH Common 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 such party shall  indemnify
and hold harmless the other party and each member of the  consolidated  group of
which the other party is a member from and  against any and all  federal,  state
and local taxes, including any interest,  penalties or additions to tax, imposed
upon or incurred by such other party, any member of its group or any stockholder
of either party 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).  The obligation
of the  Corporation to indemnify IMS HEALTH  pursuant to the preceding  sentence
shall not be  affected  by the  delivery  of any legal  opinion or  supplemental
ruling under Section 2.10(c).

     SECTION II.11. Transfers Not Effected Prior to the Distribution;  Transfers
Deemed Effective as of the  Distribution  Date. To the extent that any transfers
contemplated  by this Article II shall not have been  consummated on or prior to
the  Distribution  Date, the parties shall cooperate to effect such transfers as
promptly following the Distribution Date as shall be practicable. Nothing herein
shall be deemed to require the transfer of any Assets or the  assumption  of any
Liabilities  which by their  terms or  operation  of law cannot be  transferred;
provided,  however,  that the parties hereto and their  respective  Subsidiaries
shall  cooperate to seek to obtain any  necessary  consents or approvals for the
transfer of all Assets and Liabilities  contemplated to be transferred  pursuant
to this Article II. In the event that any such transfer of Assets or Liabilities
has not been  consummated,  from  and  after  the  Distribution  Date the  party
retaining such Asset or Liability shall hold such Asset in trust for the use and
benefit of the party  entitled  thereto  (at the  expense of the party  entitled
thereto)  or retain  such  Liability  for the  account of the party by whom such
Liability is to be assumed  pursuant  hereto,  as the case may be, and take such
other action as may be  reasonably  requested by the party to whom such Asset is
to be transferred,  or by whom such Liability is to be assumed,  as the case may
be, in order to place such party, insofar as is reasonably possible, in the same
position as would have existed had such Asset or Liability  been  transferred as
contemplated   hereby.   As  and  when  any  such  Asset  or  Liability  becomes
transferable, such transfer shall be effected forthwith. The parties agree that,
as of the Distribution  Date, each party hereto shall be deemed to have acquired
complete and sole beneficial ownership over all of the Assets, together with all
rights,  powers and  privileges  incident  thereto,  and shall be deemed to have
assumed in accordance  with the terms of this Agreement all of the  Liabilities,
and all duties,  obligations and responsibilities  incident thereto,  which such
party is entitled to acquire or required to assume pursuant to the terms of this
Agreement.

     SECTION II.12. Conveyancing and Assumption Instruments.  In connection with
the transfers of Assets and the assumptions of Liabilities  contemplated by this
Agreement,  the parties shall execute or cause to be executed by the appropriate
entities the Conveyancing and Assumption  Instruments in substantially  the form
contemplated hereby for transfers to be effected pursuant to New York law or the
laws of one of the other states of the United States or, if not  appropriate for
a given transfer, and for transfers to be effected pursuant to non-U.S. laws, in
such other form as the parties shall reasonably agree, including the transfer of
real  property with deeds as may be  appropriate.  The transfer of capital stock
shall be effected by means of delivery of stock  certificates and executed stock
powers and notation on the stock record books of the  corporation or other legal
entities  involved,  or by such other means as may be  required in any  non-U.S.
jurisdiction  to  transfer  title  to  stock  and,  to the  extent  required  by
applicable law, by notation on public registries.

     SECTION II.13. Ancillary Agreements.  On or prior to the Distribution Date,
each  of the  Corporation  and  IMS  HEALTH  shall  enter  into,  and/or  (where
applicable)  shall cause  members of the NMR Group or the IMS HEALTH  Group,  as
applicable,  to enter into, the Ancillary Agreements and any other agreements in
respect of the  Distribution  reasonably  necessary or appropriate in connection
with the transactions contemplated hereby and thereby.

     SECTION  II.14.  Corporate  Names.  (a)  Except as  otherwise  specifically
provided in any Ancillary Agreement:

          (i) on or prior to the Distribution Date, the Corporation shall change
     its name to remove any reference to "Cognizant" therein;

          (ii) as soon as reasonably practicable after the Distribution Date but
     in any event within six months thereafter, the Corporation will, at its own
     expense,  remove (or, if necessary,  on an interim basis, cover up) any and
     all exterior signs and other identifiers  located on any of its property or
     premises  or on the  property or  premises  used by it or its  Subsidiaries
     (except  property  or  premises  to  be  shared  with  IMS  HEALTH  or  its
     Subsidiaries after the Distribution) which refer or pertain to Cognizant or
     which  include  the  Cognizant  name,  logo or  other  trademark  or  other
     intellectual property utilizing Cognizant;

          (iii) as soon as reasonably  practicable  after the Distribution  Date
     but in any event within six months  thereafter,  the Corporation  will, and
     will cause its  Subsidiaries  to,  remove from all  letterhead,  envelopes,
     invoices and other  communications  media of any kind,  all  references  to
     Cognizant,  including the "Cognizant" name, logo and any other trademark or
     other   intellectual   property   utilizing   Cognizant  (except  that  the
     Corporation  shall not be required to take any such action with  respect to
     materials in the possession of customers),  and neither the Corporation nor
     its Subsidiaries  shall use or display the "Cognizant"  name, logo or other
     trademarks or intellectual  property utilizing  Cognizant without the prior
     written  consent  of  any  assignee  of  the  Corporation's  rights  to the
     "Cognizant"  name,  logo  or  other  trademarks  or  intellectual  property
     utilizing Cognizant;

          (iv) as soon as reasonably  practicable  after the Distribution  Date,
     but in any event within six months  thereafter,  the Corporation will cause
     its Subsidiaries to change their corporate names to the extent necessary to
     remove and eliminate any reference to Cognizant,  including the "Cognizant"
     name; provided, however, that notwithstanding the foregoing requirements of
     this Section  2.14(a),  if the Corporation has exercised good faith efforts
     to comply with this clause (iv) but is unable,  due to  regulatory or other
     circumstance  beyond its  control,  to effect a  corporate  name  change in
     compliance with applicable law, then the Corporation or its Subsidiary will
     not be deemed to be in breach hereof if it continues to exercise good faith
     efforts to effectuate such name change and does effectuate such name change
     within nine months after the Distribution Date, and, in such circumstances,
     such party may continue to include in exterior signs and other  identifiers
     and in letterhead,  envelopes, invoices and other communications references
     to the name which includes references to Cognizant,  but only to the extent
     necessary to identify such party and only until such party's corporate name
     can be changed to remove and eliminate such references; and

          (v)  notwithstanding  the foregoing clauses (i) through (iv),  nothing
     herein or in any Ancillary  Agreement shall require the Corporation to take
     any action to remove any reference to Cognizant,  including the "Cognizant"
     name,  from any stock  certificate  relating to shares of Cognizant  Common
     Stock outstanding on or prior to the Effective Time;

<PAGE>

                                                                              26


     provided  that from and after the  Effective  Time,  any newly issued stock
     certificates  representing  Cognizant  Common Stock (which at the Effective
     Time  will  become  NMR  Common  Stock)  shall  not have any  reference  to
     Cognizant, including the "Cognizant" name.

     (b) Except as otherwise specifically provided in any Ancillary Agreement:

          (i) as soon as reasonably  practicable after the Distribution Date but
     in any event  within six months  thereafter,  IMS HEALTH  will,  at its own
     expense,  remove (or, if necessary,  on an interim basis, cover up) any and
     all exterior signs and other identifiers located on any of their respective
     property or premises owned or used by them or their respective Subsidiaries
     (except  property  or premises  to be shared  with the  Corporation  or its
     Subsidiaries after the Distribution) which refer or pertain to NMR or which
     include the  "Nielsen  Media  Research" or  "Nielsen"  name,  logo or other
     trademark or other NMR intellectual property;

          (ii) as soon as reasonably practicable after the Distribution Date but
     in any event within six months thereafter,  IMS HEALTH will, and will cause
     its  respective  Subsidiaries  to, remove from all  letterhead,  envelopes,
     invoices and other communications media of any kind, all references to NMR,
     including  the "Nielsen  Media  Research" or "Nielsen"  name,  logo and any
     other trademark or other NMR intellectual  property (except that IMS HEALTH
     shall not be required to take any such action with  respect to materials in
     the  possession  of  customers),  and  neither  IMS  HEALTH  nor any of its
     Subsidiaries shall use or display the "Nielsen Media Research" or "Nielsen"
     name, logo or other  trademarks or NMR  intellectual  property  without the
     prior written consent of the Corporation; and

          (iii) as soon as reasonably  practicable  after the Distribution  Date
     but in any event within six months  thereafter,  IMS HEALTH will,  and will
     cause its  Subsidiaries  to,  change  their  corporate  names to the extent
     necessary  to remove and  eliminate  any  reference to NMR,  including  the
     "Nielsen  Media  Research"  or  "Nielsen"  name;  provided,  however,  that
     notwithstanding the foregoing  requirements of this Section 2.14(b), if IMS
     HEALTH has  exercised  good faith  efforts to comply with this clause (iii)
     but is unable, due to regulatory or other circumstance  beyond its control,
     to effect a corporate name change in compliance  with  applicable law, then
     IMS HEALTH or its  Subsidiary  will not be deemed to be in breach hereof if
     it continues to exercise good faith efforts to effectuate  such name change
     and  does  effectuate  such  name  change  within  nine  months  after  the
     Distribution Date, and, in such  circumstances,  such party may continue to
     include  in  exterior  signs  and  other  identifiers  and  in  letterhead,
     envelopes,  invoices and other communications  references to the name which
     includes  references  to NMR but only to the extent  necessary  to identify
     such  party and only until such  party's  corporate  name can be changed to
     remove and eliminate such references.

ARTICLE III.  INDEMNIFICATION

     SECTION  III.1.  Indemnification  by the  Corporation.  Except as otherwise
specifically  set forth in any  provision of this  Agreement or of any Ancillary
Agreement,  the Corporation  shall  indemnify,  defend and hold harmless the IMS
HEALTH Indemnitees from and against any and all Indemnifiable  Losses of the IMS
HEALTH Indemnitees  arising out of, by reason of or otherwise in connection with
the NMR  Liabilities  or alleged NMR  Liabilities,  including  any breach by the
Corporation of any provision of this Agreement or any Ancillary Agreement.

     SECTION  III.2.   Indemnification  by  IMS  HEALTH.   Except  as  otherwise
specifically  set forth in any  provision of this  Agreement or of any Ancillary
Agreement,  IMS  HEALTH  shall  indemnify,  defend  and  hold  harmless  the NMR
Indemnitees  from  and  against  any and  all  Indemnifiable  Losses  of the NMR
Indemnitees arising out of, by reason of or otherwise in connection with the IMS
HEALTH  Liabilities or alleged IMS HEALTH  Liabilities,  including any breach by
IMS HEALTH of any provision of this Agreement or any Ancillary Agreement.

     SECTION III.3. Procedures for Indemnification.

     (a)  Third  Party  Claims.  If a claim or  demand  is made  against  an NMR
Indemnitee or a 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
Section   3.1  or  Section  3.2  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,  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 

<PAGE>

                                                                              28


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 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.

     If the  Indemnifying  Party  acknowledges in writing  responsibility  for a
Third Party Claim, then 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;  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,
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) 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.

     (c) 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.  ACCESS TO INFORMATION

     SECTION IV.1. Provision of Corporate Records.

     (a) Other than in circumstances in which indemnification is sought pursuant
to Article III (in which event the  provisions  of such  Article  will  govern),
after the  Distribution  Date,  upon the prior written request by IMS HEALTH for
specific  and  identified  agreements,   documents,   books,  records  or  files
(collectively,  "Records")  which relate to (x) IMS HEALTH or the conduct of the
IMS HEALTH Business up to the Effective Time, or (y) any Ancillary  Agreement to
which the Corporation and IMS HEALTH are parties, as applicable, the Corporation
shall arrange, as soon as reasonably  practicable  following the receipt of such
request,  for the  provision  of  appropriate  copies  of such  Records  (or the
originals thereof if IMS HEALTH has a reasonable need for such originals) in the
possession or control of the Corporation or any of its Subsidiaries, but only to
the  extent  such  items are not  already  in the  possession  or control of IMS
HEALTH.

     (b) Other than in circumstances in which indemnification is sought pursuant
to Article III (in which event the  provisions  of such  Article  will  govern),
after the  Distribution  Date, upon the prior written request by the Corporation
for specific and identified Records which relate to (x) the Corporation,  NMR or
the conduct of the NMR Business up to the  Effective  Time, or (y) any Ancillary
Agreement to which IMS HEALTH and the  Corporation  are parties,  as applicable,
IMS HEALTH  shall  arrange,  as soon as  reasonably  practicable  following  the
receipt of such request, for the provision of appropriate copies of such Records
(or the  originals  thereof if the  Corporation  has a reasonable  need for such
originals)  in  the   possession  or  control  of  IMS  HEALTH  or  any  of  its
Subsidiaries,  but  only  to the  extent  such  items  are  not  already  in the
possession or control of the Corporation.

     SECTION IV.2.  Access to Information.  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 the
Corporation  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 (x) such other
party or the  conduct of its  business  prior to the  Effective  Time or (y) any
Ancillary  Agreement to which each of the party  requesting  such access and the
party requested to grant such access are parties.

     SECTION IV.3. Reimbursement;  Other Matters. Except to the extent otherwise
contemplated by any Ancillary Agreement,  a party providing Records 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 Records or access to
information.

     SECTION  IV.4.  Confidentiality.  Each  of  (i)  the  Corporation  and  its
Subsidiaries  and (ii) IMS HEALTH and its  Subsidiaries  shall not use or permit
the use of (without the prior written  consent of the other) and shall keep, and
shall cause its consultants and advisors 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  has been in the public  domain
through no fault of such party or (B) such  information  has been later lawfully
acquired  from other  sources by such party or (C) this  Agreement  or any other
Ancillary  Agreement or any other agreement entered into pursuant hereto permits
the use or disclosure of such  information)  to the extent such  information (w)
relates  to or was  acquired  during the period up to the  Effective  Time,  (x)
relates to any Ancillary Agreement,  (y) is obtained in the course of performing
services  for the other party  pursuant to any  Ancillary  Agreement,  or (z) is
based upon or is derived from  information  described in the  preceding  clauses
(w), (x) or (y), 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 affected party or parties prior to such disclosure.

     SECTION IV.5.  Privileged Matters.  The parties hereto recognize that legal
and other professional  services that have been and will be provided on or prior
to the Distribution  Date have been and will be rendered for the benefit of each
of the  Corporation,  the  members  of the NMR Group and the  members of the IMS
HEALTH Group, and that each of the Corporation, the members of the NMR Group and
the  members of the IMS HEALTH  Group  should be deemed to be the client for the
purposes of asserting all privileges which may be asserted under applicable law.
To allocate the interests of each party in the information as to which any party
is entitled to assert a privilege, the parties agree as follows:

<PAGE>

                                                                              31


     (a) The  Corporation  shall be  entitled,  in  perpetuity,  to control  the
assertion or waiver of all privileges in connection with privileged  information
which  relates  solely  to the  NMR  Business,  whether  or not  the  privileged
information is in the  possession of or under the control of the  Corporation or
IMS HEALTH.  The Corporation shall also be entitled,  in perpetuity,  to control
the  assertion  or  waiver  of all  privileges  in  connection  with  privileged
information that relates solely to the subject matter of any claims constituting
NMR  Liabilities,  now pending or which may be  asserted  in the future,  in any
lawsuits or other proceedings  initiated against or by the Corporation,  whether
or not the  privileged  information is in the possession of or under the control
of the Corporation or IMS HEALTH.

     (b) IMS HEALTH shall be entitled,  in perpetuity,  to control the assertion
or waiver of all  privileges in connection  with  privileged  information  which
relates  solely  to the IMS  HEALTH  Business,  whether  or not  the  privileged
information is in the  possession of or under the control of the  Corporation or
IMS HEALTH.  IMS HEALTH shall also be entitled,  in  perpetuity,  to control the
assertion or waiver of all privileges in connection with privileged  information
which relates solely to the subject matter of any claims constituting IMS HEALTH
Liabilities, now pending or which may be asserted in the future, in any lawsuits
or other  proceedings  initiated  against  or by IMS  HEALTH  whether or not the
privileged  information  is in the  possession  of or under the  control  of the
Corporation or IMS HEALTH.

     (c) The parties hereto agree that they shall have a shared privilege,  with
equal right to assert or waive, subject to the restrictions in this Section 4.5,
with respect to all privileges  not allocated  pursuant to the terms of Sections
4.5(a) and (b). All privileges relating to any claims, proceedings,  litigation,
disputes,  or other matters which involve both the Corporation and IMS HEALTH in
respect of which both parties retain any  responsibility or liability under this
Agreement, shall be subject to a shared privilege among them.

     (d) No party hereto may waive any privilege  which could be asserted  under
any applicable law, and in which the other party hereto has a shared  privilege,
without the consent of the other party, except to the extent reasonably required
in  connection  with  any  litigation  with  third-parties  or  as  provided  in
subsection  (e) below.  Consent  shall be in  writing,  or shall be deemed to be
granted  unless  written  objection is made within twenty (20) days after notice
upon the other party requesting such consent.

     (e) In the event of any  litigation or dispute  between or among any of the
parties  hereto,  any party and a  Subsidiary  of  another  party  hereto,  or a
Subsidiary of one party hereto and a Subsidiary of another party hereto,  either
such  party  may  waive a  privilege  in  which  the  other  party  has a shared
privilege,  without obtaining the consent of the other party, provided that such
waiver  of a  shared  privilege  shall  be  effective  only  as to  the  use  of
information with respect to the litigation or dispute between the parties and/or
their  Subsidiaries,  and shall not operate as a waiver of the shared  privilege
with respect to third parties.

     (f) If a  dispute  arises  between  or among  the  parties  hereto or their
respective  Subsidiaries  regarding  whether  a  privilege  should  be waived to
protect or advance the  interest of any 

<PAGE>

                                                                              32


party,  each party agrees that it shall negotiate in good faith,  shall endeavor
to minimize  any  prejudice  to the rights of the other  parties,  and shall not
unreasonably  withhold consent to any request for waiver by another party.  Each
party hereto specifically agrees that it will not withhold consent to waiver for
any purpose except to protect its own legitimate interests.

     (g) Upon  receipt by any party hereto or by any  Subsidiary  thereof of any
subpoena,  discovery or other request which arguably calls for the production or
disclosure of information  subject to a shared  privilege or as to which another
party  has the sole  right  hereunder  to  assert a  privilege,  or if any party
obtains knowledge that any of its or any of its Subsidiaries'  current or former
directors,  officers, agents or employees have received any subpoena,  discovery
or other  requests which arguably calls for the production or disclosure of such
privileged  information,  such party  shall  promptly  notify the other party or
parties of the  existence  of the request  and shall  provide the other party or
parties a reasonable  opportunity  to review the  information  and to assert any
rights it or they may have under this  Section 4.5 or  otherwise  to prevent the
production or disclosure of such privileged information.

     (h) The  transfer  of all Records  and other  information  pursuant to this
Agreement  is made in  reliance  on the  agreement  of the  Corporation  and IMS
HEALTH, as set forth in Sections 4.4 and 4.5, to maintain the confidentiality of
privileged information and to assert and maintain all applicable privileges. The
access to information being granted pursuant to Sections 4.1 and 4.2 hereof, the
agreement to provide witnesses and individuals  pursuant to Sections 2.9 and 3.3
hereof,  the furnishing of notices and documents and other  cooperative  efforts
contemplated by Section 3.3 hereof,  and the transfer of privileged  information
between and among the parties and their respective Subsidiaries pursuant to this
Agreement  shall not be deemed a waiver of any privilege that has been or may be
asserted under this Agreement or otherwise.

     SECTION IV.6. Ownership of Information.  Any information owned by one party
or any of its  Subsidiaries  that is provided to a requesting  party pursuant to
Article  III or this  Article IV shall be deemed to remain the  property  of the
providing party. Unless specifically set forth herein, nothing contained in this
Agreement  shall be  construed  as granting or  conferring  rights of license or
otherwise in any such information.

     SECTION  IV.7.  Limitation  of  Liability.  (a) No  party  shall  have  any
liability  to any other  party in the event that any  information  exchanged  or
provided  pursuant to this Agreement which is an estimate or forecast,  or which
is based on an estimate or forecast, is found to be inaccurate.

     (b) Other than in connection  with Section 2.2, no party or any  Subsidiary
thereof  shall  have any  liability  or claim  against  any  other  party or any
Subsidiary of any other party based upon,  arising out of or resulting  from any
agreement,  arrangement, course of dealing or understanding existing on or prior
to the Distribution  Date (other than this Agreement or any Ancillary  Agreement
or any agreement  entered into in connection  herewith or in order to consummate
the  transactions  contemplated  hereby  or  thereby),  unless  such  agreement,
arrangement,  course of dealing or  understanding  is listed on Schedule  4.7(b)
hereto, and any such liability or 

<PAGE>

                                                                              33


claim,  whether or not in writing,  which is not reflected on such Schedule,  is
hereby irrevocably cancelled, released and waived.

     SECTION IV.8. Other Agreements  Providing for Exchange of Information.  The
rights and obligations granted under this Article IV are subject to any specific
limitations, qualifications or additional provisions on the sharing, exchange or
confidential treatment of information set forth in any Ancillary Agreement.


ARTICLE V.  ADMINISTRATIVE SERVICES

     SECTION V.1.  Performance of Services.  Beginning on the Distribution Date,
each party will provide, or cause one or more of its Subsidiaries to provide, to
the other party and its  Subsidiaries  such services on such terms as may be set
forth in the Shared  Transaction  Services  Agreement.  Except as otherwise  set
forth in such  agreement or any Schedule  thereto,  the party that is to provide
the services (the  "Provider") will use (and will cause its Subsidiaries to use)
commercially reasonable efforts to provide such services to the other party (the
"Recipient")  and its  Subsidiaries  in a satisfactory  and timely manner and as
further specified in such agreement.

     SECTION  V.2.  Independence.   Unless  otherwise  agreed  in  writing,  all
employees and  representatives  of the Provider providing the scheduled services
to the Recipient  will be deemed for purposes of all  compensation  and employee
benefits  matters to be  employees  or  representatives  of the Provider and not
employees or representatives of the Recipient. In performing such services, such
employees  and  representatives  will  be  under  the  direction,   control  and
supervision  of the Provider (and not the  Recipient) and the Provider will have
the sole  right  to  exercise  all  authority  with  respect  to the  employment
(including,  without  limitation,  termination  of  employment),  assignment and
compensation of such employees and representatives.

     SECTION V.3. Non-exclusivity. Nothing in this Agreement precludes any party
from  obtaining,  in  whole  or in  part,  services  of any  nature  that may be
obtainable  from the other party from its own employees or from providers  other
than the other party.


ARTICLE VI.  DISPUTE RESOLUTION

<PAGE>

                                                                              34


     SECTION VI.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 otherwise
arising  out of, or in any way  related to this  Agreement  or the  transactions
contemplated hereby, including, without limitation, any claim based on contract,
tort,  statute or constitution (but excluding any controversy,  dispute or claim
arising out of any  agreement  relating to the use or lease of real  property if
any third party is a party to such controversy, dispute or claim) (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  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 6.2 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 any  Ancillary  Agreement  to which such
Agreement  Dispute  relates  shall  not be  deemed  to have  passed  until  such
Agreement Dispute has been resolved.

     SECTION VI.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.  '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 VI 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  8.17  hereof.  The  arbitrator  shall be entitled,  if
appropriate,  to  award  any  remedy  in such  proceedings,  including,  without
limitation,  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  

<PAGE>

                                                                              35


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  VI.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 and each Ancillary  Agreement during the
course of dispute resolution  pursuant to the provisions of this Article VI with
respect to all matters not subject to such dispute, controversy or claim.


ARTICLE VII.  INSURANCE

     SECTION VII.1.  Policies and Rights Included  Within Assets;  Assignment of
Policies. (a) Policy Rights. The IMS HEALTH Assets shall include (i) any and all
rights of an insured  party  under each of the Shared  Policies,  subject to the
terms of such Shared  Policies and any  limitations or obligations of IMS HEALTH
contemplated by this Article VII, 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 by any party in or in connection  with the conduct of the IMS
HEALTH Business or, to the extent any claim is made against IMS HEALTH or any of
its  Subsidiaries,  the conduct of the NMR Business,  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.

     (b)  Assignment  of Shared  Policies.  Subject to the terms and  conditions
hereof, the Corporation hereby assigns,  transfers and conveys to IMS HEALTH all
of the  Corporation's  right,  title and  interest  in and to any and all of the
Shared Policies,  including,  without  limitation,  the right of indemnity,  the
right to be  defended  by or at the  expense of the insurer and the right to any
applicable  Insurance  Proceeds  thereunder;  and the Corporation and IMS HEALTH
shall use their commercially  reasonable efforts to obtain any required consents
of insurers to the assignment contemplated by this paragraph.

     SECTION  VII.2.  Post-Distribution  Date  Claims.  If,  subsequent  to  the
Distribution  Date, any person shall assert a claim against IMS HEALTH or any of
its  Subsidiaries  (including,  without  limitation,  where  IMS  HEALTH  or its
Subsidiaries are joint defendants with other persons) with respect to any claim,
suit, action, proceeding, injury, loss, liability, damage or expense incurred or
claimed  to have been  incurred  on or prior to the  Distribution  Date in or in
connection  with the  conduct of the IMS HEALTH  Business  or, to the extent any
claim is made against IMS HEALTH or any of its Subsidiaries (including,  without
limitation, where IMS HEALTH or its Subsidiaries are joint defendants with other
persons),  in connection with the conduct of the NMR Business,  and 

<PAGE>

                                                                              36


which claim,  suit,  action,  proceeding,  injury,  loss,  liability,  damage or
expense may arise out of an insured or insurable occurrence under one or more of
the Shared Policies,  the Corporation shall, at the time such claim is asserted,
to the extent any such Policy may require that Insurance Proceeds  thereunder be
collected  directly by the named  insured or anyone other than the party against
whom the Insured  Claim is  asserted,  be deemed to  designate,  without need of
further  documentation,  IMS HEALTH as the agent and  attorney-in-fact to assert
and to collect any related Insurance Proceeds under such Shared Policy.

     SECTION VII.3. Administration; Other Matters. (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 NMR  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 7.3 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 7.3(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 longer be in effect with respect to insurance  and
risk  management,  then  each  of  the  Corporation  and  IMS  HEALTH  shall  be
responsible for its own Claims Administration and Insurance Administration.

     (b) Exceeding  Policy Limits.  The  Corporation and IMS HEALTH shall not be
liable to one another for claims not  reimbursed  by insurers for any reason not
within  the  control  of the  Corporation  or IMS  HEALTH,  as the  case may be,
including, without limitation, 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 the  Corporation  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 Shared Policies shall be paid to
IMS HEALTH, which shall thereafter  administer the Shared Policies by paying the
Insurance  Proceeds,  as  appropriate,  to the  Corporation  with respect to NMR
Liabilities and to IMS HEALTH with respect to IMS HEALTH 

<PAGE>

                                                                              37


Liabilities.  Payment of the allocable  portions of indemnity costs of Insurance
Proceeds  resulting  from  such  Policies  will  be made  by IMS  HEALTH  to the
appropriate party upon receipt from the insurance carrier. 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 to
allocate the Insurance Proceeds received  thereunder based upon their respective
percentage  of the total of their bona fide claims which were covered under such
Shared Policy (their "allocable portion of Insurance  Proceeds"),  and 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 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 each such  party  bears to the total  Insurance  Proceeds
received  under the  applicable  Shared  Policy (their  "allocable  share of the
deductible"),  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.

     (e) After the  Distribution  Date,  each of IMS HEALTH and the  Corporation
shall be responsible  for its applicable  deductible for workers'  compensation,
general liability and automobile liability claims.

     SECTION VII.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
VII 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  VII.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 VIII.  MISCELLANEOUS

     SECTION VIII.1. Complete Agreement; Construction. This Agreement, including
the Exhibits and Schedules,  and the Ancillary  Agreements  shall constitute the
entire  agreement  between the parties with respect to the subject matter hereof
and shall  supersede all previous  negotiations,  commitments  and writings with
respect to such subject matter. In the event of any  inconsistency  between this
Agreement  and any Schedule  hereto,  the  Schedule  shall  prevail.  Other than
Section  2.1(j),  Section 2.7,  Section 4.5 and Article VI, which shall  prevail
over any  inconsistent  or  conflicting  provisions in any Ancillary  Agreement,
notwithstanding  any other provisions in this Agreement to the contrary,  in the
event and to the extent that there shall be a conflict between the provisions of
this  Agreement and the  provisions of any Ancillary  Agreement,  such Ancillary
Agreement shall control.

     SECTION  VIII.2.  Ancillary  Agreements.  Subject to the last  sentence  of
Section  8.1,  this  Agreement  is not  intended to  address,  and should not be
interpreted to address,  the matters  specifically and expressly  covered by the
Ancillary Agreements.

     SECTION VIII.3. Counterparts. This Agreement may be executed in one or more
counterparts,  all of which shall be considered one and the same agreement,  and

this  Agreement,  all covenants and agreements of the parties  contained in this
Agreement shall survive the Distribution Date.

otherwise set forth in this Agreement or any Ancillary Agreement,  all costs and
expenses  incurred and for which invoices have been submitted on or prior to the

required  implementation  of this  Agreement  and any Ancillary  Agreement,  the
Information  Statement (including any registration  statement on Form 10 (or any
amendment  thereto) of which such  Information  Statement may be a part) and the
Distribution and the consummation of the transactions contemplated thereby shall

STATE OF NEW YORK  APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED IN THE STATE
OF NEW YORK.

     SECTION VIII.17.  Consent to Jurisdiction.  Without limiting the provisions
of Article VI hereof,  each of the parties  irrevocably submits to the exclusive
jurisdiction of (a) the Supreme Court of the State of New York, New York County,
and (b) the United States District Court for the Southern  District of New York,
for the  purposes of any suit,  action or other  proceeding  arising out of this
Agreement or any transaction  contemplated hereby. Each of the parties agrees to
commence any action,  suit or  proceeding  relating  hereto either in the United
States  District  Court for the  Southern  District of New York or if such suit,
action or other  proceeding may not be brought in such court for  jurisdictional
reasons, in the Supreme Court of the State of New York, New York County. Each of
the parties  further  agrees that  service of any  process,  summons,  notice or
document by U.S.  registered mail to such party's  respective  address set forth

unconditionally  waives any objection to the laying of venue of any action, suit
or proceeding  arising out of this  Agreement or the  transactions  contemplated
hereby in (i) the Supreme  Court of the State of New York,  New York County,  or
(ii) the United States District Court for the Southern District of New York, and

provisions  contained  in this  Agreement  should be held  invalid,  illegal  or
unenforceable in any respect,  the validity,  legality and enforceability of the
remaining  provisions  contained  herein  and  therein  shall  not in any way be
affected  or  impaired  thereby.   The  parties  shall  endeavor  in  good-faith
negotiations to replace the invalid,  illegal or  unenforceable  provisions with
valid  provisions,  the  economic  effect of which comes as close as possible to
that of the invalid, illegal or unenforceable provisions.

Dear Ms. Henry and Mr. Doppelt:

     Reference is made to the  Distribution  Agreement  (the "1996  Distribution
Agreement"),   dated  as  of  October  28,  1996,  among  Cognizant  Corporation
("Cognizant"),   The  Dun  &  Bradstreet   Corporation   ("D&B")  and  ACNielsen
Corporation  ("ACNielsen").  Cognizant  has  announced its intention to separate
into  two  separate   companies   through  a   distribution   (the  "IMS  HEALTH
Distribution")  to its  stockholders of all of the shares of common stock of its
subsidiary IMS Health Incorporated ("IMS HEALTH"). In Section 8.9(c) of the 1996
Distribution Agreement,  Cognizant agreed not to make a distribution such as the
IMS HEALTH  Distribution unless it caused the distributed entity to undertake to
both D&B and  ACNielsen  to be jointly and  severally  liable for all  Cognizant
Liabilities  (as  defined in 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 IMS HEALTH
Distribution,  IMS HEALTH  undertakes to each of D&B and ACNielsen to be jointly
and severally liable with Cognizant for all Cognizant Liabilities under the 1996
Distribution Agreement.

Very truly yours,

IMS HEALTH INCORPORATED

                                                              Schedule 2.1(j)(i)


    Allocation of Liabilities Relating to Certain Prior Business Transactions


     1. Any and all Liabilities of Cognizant for any audit  adjustments to Taxes
arising  out of the  transactions  and  related  agreements  known as (a)  Nieuw
Willemstad  Partnership or Oud Philipsburg  Partnership,  involving A.C. Nielsen
Company and The Dun & Bradstreet  Corporation;  (b) Duns  Licensing  Associates,
L.P.,  involving  Dun &  Bradstreet,  Inc.  and IMS America,  Ltd.;  and (c) D&B
Investors,  L.P., involving Reuben H. Donnelley  Corporation,  IMS America, Ltd.
and Dun & Bradstreet,  Inc. shall be allocated as follows:  (x) IMS HEALTH shall
be liable for and shall pay all such Taxes  allocated to  Cognizant  pursuant to
Section  2.1(j)(ii) of the 1996 Distribution  Agreement until such Taxes, in the
aggregate,  equal one hundred and thirty million dollars; and (y) IMS HEALTH and
the  Corporation  shall  each be liable for and shall pay  one-half  of any such
Taxes  allocated  to  Cognizant  pursuant  to  Section  2.1(j)(ii)  of the  1996
Distribution  Agreement  in excess of one  hundred and thirty  million  dollars;
provided,  that the Corporation's aggregate liability for Taxes pursuant to this
paragraph and for amounts  described in Section  2.1(j)(ii) of the  Distribution
Agreement  shall  not  exceed  one  hundred  and  twenty-five  million  dollars;
provided,  further, that prior to January 1, 2001, IMS HEALTH shall make any and
all  payments  for all of the Taxes  referred  to in clause (y) above,  with the
Corporation  reimbursing IMS HEALTH for its  proportionate  share thereof on the
first business day after such date.

     2. The  liability  for any audit  adjustments  to Taxes  arising out of the
transactions and related agreements known as Dun & Bradstreet  Computer Leasing,
Inc. and Fillupar Leasing Partnership shall be allocated solely to IMS HEALTH.

     3. To the  extent  that  the  allocation  of  liability  for  Taxes in this
Schedule 2.1(j) results in the sharing of liability for Taxes between IMS HEALTH
and the Corporation,  Section 5.1 of the Tax Allocation Agreement, governing Tax
Audits and  Controversies,  shall be  applied  as though  IMS HEALTH  alone were
liable for all such Taxes and the  Corporation  were not liable for such  Taxes;
provided,  however, that IMS HEALTH shall not enter into any final settlement or
closing agreement without the consent of the Corporation,  which consent may not
be  unreasonably  withheld.  Where  consent to any final  settlement  or closing
agreement  is  withheld,  the  Corporation  shall  continue or initiate  further
proceedings,  at its own  expense,  and the  liability  of IMS  HEALTH  shall be
limited  to the  liability  that  would have  resulted  for IMS HEALTH  from the
proposed closing agreement or final settlement (including interest, additions to
tax and penalties which have accrued at that time).




                                                                    Exhibit 10.2

                            TAX ALLOCATION AGREEMENT

     ARTICLE PREPARATION AND FILING OF TAX RETURNS

     SECTION Predistribution Tax Returns.

     IMS HEALTH (or its  relevant  Controlled  Entity)  shall  prepare,  and the
Corporation (or its relevant Controlled Entity) shall file, (i) all Consolidated
Returns, Combined Returns,  Non-Combined Returns, and Franchise Tax Returns that
are not filed  prior to the  Distribution  Date and (ii) any Tax  Returns of any
partnership (other than NMR Licensing Associates LP) of which the Corporation or
any Subsidiary is the Tax Matters Partner if a distributive share of partnership
income or loss is included in any such Return.

     All Tax  Returns  for  Other  Taxes  for  periods  beginning  prior  to the
Distribution Date that are not subject to the D&B Tax Allocation Agreement shall
be  prepared  and filed by IMS  HEALTH if they  relate to any  member of the IMS
HEALTH Group and, otherwise, by the Corporation.

     SECTION Post-Distribution Tax Returns.

     The  filing  of all Tax  Returns  for  periods  beginning  on or after  the
Distribution  Date (other than  Non-Combined  Returns and  Franchise Tax Returns
covered by Section  2.1(a)) shall be the  responsibility  of the  Corporation if
they  relate  to  the  NMR  Group  or  any  member  thereof  and  shall  be  the
responsibility  of IMS  HEALTH  if they  relate to the IMS  HEALTH  Group or any
member thereof.

     In the case of any  partnership  in which a member of the  Pre-Distribution
Cognizant  Group is the  designated  Tax  Matters  Partner,  such  entity  shall
continue to be responsible for the preparation and filing of such  partnership's
Tax Returns.

     SECTION Manner of Preparation.

     To the extent any Tax Return  includes Taxes relating to a Party (or any of
its Subsidiaries) other than the Party preparing such Tax Return (the "Preparing
Party"),  the Party not  responsible for preparing the Tax Return (the "Included
Party"),  shall  prepare and deliver to the Preparing  Party,  at least 120 days
prior to the due date  (including  extensions)  of such Tax  Return,  a true and
correct accounting of all relevant Tax Items relating to the Included Party (and
any of its Subsidiaries) for the taxable period.

<PAGE>

                                                                               8


     All Tax Returns filed on or after the  Distribution  Date shall be prepared
on a basis that is  consistent  with the  rulings  obtained  from the IRS or any
other  Governmental   Authority  in  connection  with  the   Reorganizations  or
Distribution  (in the absence of a controlling  change in law or  circumstances)
and shall be filed on a timely basis  (including  pursuant to extensions) by the
Party  responsible  for such filing  under this  Agreement.  In the absence of a
controlling  change  in law or  circumstances  and  unless  deviation  from past
practice would have no adverse effect on the other Party,  all Tax Returns filed
within  three  years  after the  Distribution  Date shall be prepared on a basis
consistent with the elections, accounting methods, conventions,  assumptions and
principles  of taxation used for the most recent  taxable  periods for which Tax
Returns involving similar Tax Items have been filed;  provided,  however, that a
Party  preparing  any Tax Return  that does not  conform to such past  practices
shall not be liable for any  additional  Tax liability  imposed,  in whole or in
part, as a result of such  deviation from past practice if: (i) 30 days prior to
the filing of such Tax Return,  the Party preparing such Tax Return notifies the
other Party if such other Party may be  adversely  affected;  and (ii) the Party
preparing  such Tax  Return  establishes  that  conformity  with  past  practice
involves a  significant  risk of the  imposition  of a  penalty.  Subject to the
provisions of this Agreement,  all decisions  relating to the preparation of Tax
Returns shall be made in the sole discretion of the Party responsible under this
Agreement for its  preparation;  provided,  however,  that the "Included  Party"
shall  have the right to review  and  comment  on such Tax  Return  prior to the
filing thereof in the following manner:

     The  Preparing  Party shall submit any part of such Tax Return  relating to
the Included Party (or any of its  Subsidiaries)  to the Included Party at least
28  days  prior  to the  date  on  which  such  Tax  Return  is  due  (including
extensions). The Included Party shall submit its comments to the Preparing Party
within 14 days of receipt  of the  relevant  portions  of such Tax  Return.  The
Preparing  Party shall alter such Tax Return to reflect the reasonable  comments
of the Included Party unless the Preparing Party  reasonably  believes that such
alteration would have an adverse impact upon the Preparing Party.

     Unless  otherwise  required by the IRS,  any  Governmental  Authority  or a
court,  the Parties hereby agree to file all Tax Returns,  and to take all other
actions,  in a manner consistent with the position that the Distribution Date is
the last day on which any member of the IMS  HEALTH  Group was  included  in the
Pre-Distribution  Cognizant Group. For any period that includes but does not end
on the  Distribution  Date,  to the extent  permitted  by law or  administrative
practice,  the  taxable  year of each member of 

<PAGE>

                                                                               9


the  Pre-Distribution  Cognizant  Group and any group of such  members  shall be
treated as ending on the Distribution Date.

     ARTICLE PAYMENT OF TAXES

     SECTION Predistribution Taxes

     The Party responsible for the filing of any Tax Return pursuant to Sections
2.1 and 2.2 shall pay to the relevant taxing  authority all Taxes due or payable
in connection  therewith;  provided,  that if, pursuant to this Article III, one
Party is liable for any Taxes relating to a Tax Return filed by the other Party,
such  non-filing  Party  shall pay the filing  Party the amount of such Taxes at
least 5 days prior to the due date (including extensions) of such Tax Return.

     With respect to any  Consolidated  Return,  Combined  Return,  Non-Combined
Return or Franchise Tax Return for a taxable  period  ending  before  January 1,
1998 that is not filed  prior to the  Distribution  Date,  IMS  HEALTH  shall be
liable  for all Taxes  payable  with such  Return and shall be  entitled  to any
refund or credit for an overpayment of Taxes shown on such Return.  With respect
to any Consolidated  Return,  Combined Return,  Non-Combined Return or Franchise
Tax Return  for a taxable  period  beginning  on or after  January 1, 1998,  IMS
HEALTH (i) shall  only be liable for Taxes  payable  with such  Return  that are
attributable  to the  portion of such  taxable  period up to and  including  the
Distribution  Date and that  exceed  the amount of Taxes paid in respect of such
taxable period (as estimated Taxes or otherwise) on or prior to the Distribution
Date and (ii) shall be  entitled  to any refund or credit of Taxes to the extent
Taxes paid in respect of such taxable  period (as estimated  Taxes or otherwise)
on or prior to the Distribution Date exceed the amount of Taxes  attributable to
the  portion  of the  period up to and  including  the  Distribution  Date.  The
determination of the amount of Taxes attributable to the portion of such taxable
period up to and including the  Distribution  Date shall be done on a closing of
the books basis,  except that Tax Items  calculated  on an annual basis shall be
apportioned on a time basis.

     In the event of any Final  Determination  adjusting the amount of any Taxes
that are the subject of a Consolidated  Return,  Combined  Return,  Non-Combined
Return or Franchise Tax Return,  IMS HEALTH shall be liable for its share of any
increases  in Taxes and shall be entitled to its share of any refunds or credits
of Taxes,  and the Corporation  shall be liable for all other increases in Taxes
and shall be entitled  to all other  refunds or credits of Taxes.  IMS  HEALTH's
share of any Taxes,  credits or refunds shall be  determined in accordance  with
the following principles:

<PAGE>

                                                                              10


     (i) IMS HEALTH  shall be liable  for any  increase  in Taxes,  and shall be
entitled  to all  refunds or credits of Taxes,  that are  attributable  to a Tax
Return that relates solely to the IMS HEALTH Business; and

     (ii) In the case of any Tax  Return  that  relates  to both the IMS  HEALTH
Business and the NMR Business,  IMS HEALTH's share of any increase in Taxes,  or
refunds or credits of Taxes,  shall be determined on a pro forma basis as if IMS
HEALTH filed a separate Tax Return for the taxable period that (i) included only
(x) the Tax Items  attributable to the IMS HEALTH Business otherwise included in
the Tax Return and (y) an appropriate  allocation of Tax Items not  specifically
attributable to either the IMS HEALTH  Business or the NMR Business  (including,
without  limitation,  corporate  overhead)  and (ii) credits IMS HEALTH with its
share of Taxes  previously paid by the Corporation or IMS HEALTH with respect to
such taxable period;

provided,  that,  in  the  case  of  a  Consolidated  Return,  Combined  Return,
Non-Combined  Return or Franchise Tax Return, IMS HEALTH shall be liable for and
shall pay all  increases in Taxes,  and shall be entitled to receive all refunds
or credits of Taxes,  that result from a Tax Item or position  determined by the
corporate office.

     The Corporation  shall be liable for all Other Taxes that are  attributable
to the NMR  Business and IMS HEALTH shall be liable for all Other Taxes that are
attributable to the IMS HEALTH Business.

     In the  case of any  Consolidated  Return,  Combined  Return,  Non-Combined
Return  or   Franchise   Tax  Return  with  respect  to  which  IMS  HEALTH  has
responsibility  for any Taxes or is  entitled to any refunds or credits of Taxes
pursuant to Section 3.1(c) above,  IMS HEALTH shall have the right to prepare an
amended  Tax  Return.  The  Corporation  shall have the right to review any such
amended Tax Return and shall be  required to sign and file any such  amended Tax
Return  unless it  reasonably  determines  that the filing of such  amended  Tax
Return  would  create a  significant  risk of a material  increase  in the Taxes
payable by the NMR Group or any member thereof for any taxable period  beginning
on or after the  Distribution  Date. IMS HEALTH shall be entitled to any refunds
or credits of Taxes relating to any such amended Tax Return.

     If the  Corporation  is liable for any Taxes or  entitled to any refunds or
credits of Taxes  pursuant  to the D&B Tax  Allocation  Agreement,  such  Taxes,
refunds or credits shall be allocated  between the Corporation and IMS HEALTH in
accordance with the principles of this Section 3.1.

     Notwithstanding any statement herein to the contrary,  any Taxes covered by
Section  2.1(j)(i) of the  

<PAGE>

Agreement:

     The  Corporation  shall pay all Taxes and shall be  entitled to receive and
retain all refunds of Taxes attributable to the NMR Group or any member thereof:

              (i)  with  respect  to a  Consolidated  Return,  Combined  Return,
       Non-Combined  Return or  Franchise  Tax Return for a taxable  period that
       begins  prior to the  Distribution  Date and includes but does not end on
       the   Distribution   Date  to  the  extent  such  Taxes  or  refunds  are
       attributable to the portion of such period after the  Distribution  Date;
       and

              (ii)  with   respect  to  periods   beginning   on  or  after  the
       Distribution Date.

     IMS HEALTH  shall pay all Taxes and shall be entitled to receive and retain
all  refunds  of Taxes  with  respect  to  periods  beginning  on or  after  the
Distribution  Date that are  attributable  to the IMS HEALTH Group or any member
thereof.

     SECTION Restructuring Taxes.

     Notwithstanding  any statement to the contrary in this Agreement and except
as  otherwise  provided in the  Distribution  Agreement,  to the extent that any
Taxes are found to arise out of the Reorganizations, then any such Tax liability
incurred  by  the  Parties  (or  any  of  their   Subsidiaries)   shall  be  the
responsibility  of IMS HEALTH;  provided,  however,  that to the extent specific
cash  allocations for such Taxes are made in connection  with the  Distribution,
IMS  HEALTH  shall be  relieved  of its  liability  for such Taxes to the extent
covered by such cash.

     Notwithstanding any statement herein to the contrary, any Taxes relating to
or arising out of the  Distribution  shall be  governed  by Section  2.10 of the
Distribution Agreement.

     SECTION  Gain  Recognition  Agreements.  IMS HEALTH shall assume all of the
Corporation's  responsibilities  with  respect  to gain  recognition  agreements
pursuant to the D&B Tax Allocation Agreement.

     SECTION Indemnification.

     Indemnification by the Corporation. The Corporation shall indemnify, defend
and hold harmless IMS HEALTH (and its  affiliates)  from and against any and all
Tax liabilities allocated to the Corporation by this Agreement.

                                                                              12


     Indemnification by IMS HEALTH. IMS HEALTH shall indemnify,  defend and hold
harmless the Corporation  (and its affiliates)  from and against any and all Tax
liabilities allocated to IMS HEALTH by this Agreement.

     Indemnity Payments.

     To the  extent  that one Party  (the  "Indemnifying  Party")  owes money to
another  Party (the  "Indemnitee")  pursuant to this Section 3.5, the Party (the
"Notifying  Party") having  knowledge of such obligation  shall notify the other
Party  and  shall  provide  such  other  Party  with  its  calculations  of such
obligation (as specified in Article II and Article III). The other Party, within
14 days after receiving the Notifying Party's calculations,  shall submit to the
Notifying  Party such other Party's  calculations  of the amount  required to be
paid  pursuant to this Section  3.5,  showing such  calculations  in  sufficient
detail so as to permit the Notifying Party to understand the  calculations.  The
Indemnifying  Party shall pay the Indemnitee,  no later than the later of 5 days
prior to the due date (including  extensions) of the relevant Tax Returns and 14
days after the  Notifying  Party  receives the other Party's  calculations,  the
amount for which the  Indemnifying  Party is  required to pay or  indemnify  the
Indemnitee under this Section 3.5. The  Indemnifying  Party shall have the right
to disagree  with the  Indemnitee's  calculations.  Any dispute  regarding  such
calculations shall be resolved in accordance with Section 5.4 of this Agreement.

     All indemnity  payments shall be calculated on a pre-Tax basis and shall be
treated as  contributions  to capital  and/or  reductions  of assets  previously
contributed and/or dividends immediately prior to the Distribution.

     ARTICLE TAX ATTRIBUTES AND REORGANIZATION TAX PAYMENTS

     SECTION Carrybacks.  In the event of the realization of any deduction, loss
or  credit  by a  Party  for  any  taxable  period  beginning  on or  after  the
Distribution  Date, the Party realizing such  deduction,  loss or credit may, in
its sole discretion, and to the extent permitted under applicable Tax law, elect
to either carry back or carry forward such deduction, loss or credit. Any refund
attributable  to such carryback  shall be allocable to such Party.  In the event
both Parties elect to carry back an amount to the same taxable period  beginning
prior to the  Distribution  Date,  any refund shall be  apportioned  between the
Parties based on the relative carryback amounts.

     SECTION Reorganization Tax Payments,  Deferred Compensation  Deductions and
Post-Distribution Expense Deductions.

<PAGE>

                                                                              13


     If an audit or other examination of any federal,  state or local Tax Return
for any taxable  period shall result (by  settlement or otherwise) in a Deferred
Compensation  Deduction or  Post-Distribution  Expense Deduction in favor of the
NMR Group or any member thereof or if any  Reorganization Tax Payment is made by
IMS HEALTH, then:

     If necessary, IMS HEALTH shall notify the Corporation and shall provide the
Corporation with adequate  information so that it can reflect on the appropriate
Tax Returns any  resulting  increases  in  deductions,  losses or Tax credits or
decreases in income, gains or recapture of Tax credits;

     The  Corporation  shall pay IMS HEALTH the amount of any Tax  Benefit  that
relates to any  adjustments  arising from or connected with such  Reorganization
Tax  Payment  or that  results  from such  Deferred  Compensation  Deduction  or
Post-Distribution Expense Deduction within 30 days of the date such Tax Benefits
are realized;

     Notwithstanding  the foregoing,  the Corporation  shall only be required to
take steps to obtain such Tax Benefit or to pay IMS HEALTH if, in the opinion of
the Corporation's Tax counsel,  which counsel shall be reasonably  acceptable to
IMS HEALTH,  the reporting of such Tax Benefit shall not subject the Corporation
to the  imposition  of a penalty  unless  IMS  HEALTH  agrees to  indemnify  the
Corporation for such penalty.

<PAGE>

                                                                              14


     If an audit or other examination of any federal,  state or local Tax Return
for any taxable  period shall result (by  settlement or otherwise) in a Deferred
Compensation  Deduction or  Post-Distribution  Expense Deduction in favor of the
IMS HEALTH Group or any member thereof, then:

     If necessary, the Corporation shall notify IMS HEALTH and shall provide IMS
HEALTH with adequate  information so that it can reflect on the  appropriate Tax
Returns  any  resulting  increases  in  deductions,  losses  or Tax  credits  or
decreases in income, gains or recapture of Tax credits;

     IMS HEALTH  shall pay the  Corporation  the amount of any Tax Benefit  that
results from such Deferred Compensation  Deduction or Post-Distribution  Expense
Deduction within 30 days of the date such Tax Benefits are realized;

     Notwithstanding  the  foregoing,  IMS HEALTH shall only be required to take
steps to obtain such Tax Benefit or to pay the Corporation if, in the opinion of
IMS HEALTH's Tax counsel,  which counsel  shall be reasonably  acceptable to the
Corporation,  the  reporting of such Tax Benefit shall not subject IMS HEALTH to
the  imposition  of a penalty  unless the  Corporation  agrees to indemnify  IMS
HEALTH for such penalty.

     Realization of Tax Benefits.

     For  purposes of this  Section  4.2, a Tax Benefit  shall be deemed to have
been  realized at the time any refund of Taxes is  received  or applied  against
other  Taxes due,  or at the time of filing of a Tax Return  (including  any Tax
Return  relating to  estimated  Taxes) on which a loss,  deduction  or credit is
applied in  reduction  of Taxes which  would  otherwise  be  payable;  provided,
however,  that where a Party has other  losses,  deductions,  credits or similar
items available to it, such deductions,  credits or similar items may be applied
prior to the use of any adjustments  relating to a Reorganization Tax Payment or
any Deferred Compensation Deduction or Post-Distribution Expense Deduction.

     Either Party may, at its election, pay the amount of any Tax Benefit to the
other  Party  rather  than  filing  amended  returns  or  otherwise   reflecting
adjustments or taking positions on its Tax Returns. If such an election is made,
the Party will be treated as having  realized a Tax Benefit at the time it would
have  realized a Tax Benefit had it chosen to file amended  returns or otherwise
to reflect adjustments or to take positions on its Tax Returns.

                                                                              15


     Tax Benefits  Subsequently  Denied. If any Tax Benefit realized pursuant to
Section 4.2(b)(i) is subsequently denied, then IMS HEALTH or the Corporation, as
the case may be,  shall  refund the amount of any  payment  for such Tax Benefit
within 30 days of its notification by the other Party that a Final Determination
has been reached denying the claimed Tax Benefit.

     SECTION  Competent  Authority  Relief.  If as a  result  of any  audit of a
taxable period beginning prior to the Distribution Date, a Party (or Subsidiary)
is  required  to adjust its  income,  deductions,  credits or  allowances  under
Section 482 of the Code or under similar  principles in a foreign  jurisdiction,
and the payment of  additional  Taxes in  accordance  with such a  determination
allows the other Party (or Subsidiary) to obtain competent authority relief as a
result thereof,  then the Party eligible to obtain such relief shall: execute or
cause to be  executed  any powers of attorney or other  documents  necessary  to
enable the other Party to pursue such relief at its own expense;  and  cooperate
with the other Party and the competent authorities in seeking such relief.

     ARTICLE TAX AUDITS, TRANSACTIONS AND OTHER MATTERS

     SECTION Tax Audits and Controversies. In the case of any audit, examination
or other proceeding  ("Proceeding") brought against a Party (or Subsidiary) with
respect to Taxes for which the other Party is or may be liable  pursuant to this
Agreement, the Party subject to such Proceeding shall promptly inform such other
Party and shall  execute or cause to be executed any powers of attorney or other
documents  necessary to enable the other Party to take all actions  desired with
respect to such  Proceeding to the extent such  Proceeding may affect the amount
of Taxes for which the other Party is liable  pursuant to this  Agreement.  Each
Party shall have the right to control,  at its own  expense,  the portion of any
such  Proceeding  that relates to Taxes for which such Party is or may be liable
pursuant to this  Agreement;  provided,  however,  that such Party shall consult
with the other  Party with  respect to any issue that may affect the other Party
(or  Subsidiary).  The Party in control of such  Proceeding  or any part thereof
shall  not  enter  into any  final  settlement  or  closing  agreement  that may
adversely  affect the other  Party (or  Subsidiary)  without the consent of such
other Party,  which consent may not  unreasonably be withheld.  Where consent to
any final  settlement or closing  agreement is withheld,  the Party  withholding
consent shall continue or initiate further proceedings,  at its own expense, and
the  liability of the Party in control of such  Proceeding  shall not exceed the
liability that would have resulted from the proposed closing  agreement or final
settlement  (including  interest,  additions  to Tax and  penalties  which  have
accrued at that time).

<PAGE>

                                                                              16


     SECTION  Cooperation.  The  Corporation and IMS HEALTH shall cooperate with
each  other in the  filing of any Tax  Returns  and the  conduct of any audit or
other  proceeding and each shall execute and deliver such powers of attorney and
other  documents  and make  available  such  information  and  documents  as are
necessary  to  carry  out the  intent  of this  Agreement.  To the  extent  such
cooperation involves the services of officers,  directors,  employees, or agents
of a Party, such services shall be made available in accordance with Section 2.9
of the  Distribution  Agreement.  Each Party agrees to notify the other Party of
any audit adjustment that does not result in Tax liability but can reasonably be
expected to affect Tax  Returns of the other  Party or any of its  Subsidiaries.
Notwithstanding  any  other  provision  of  this  Agreement,  if  a  Party  (the
"Nonperforming  Party")  fails  to give its  full  cooperation  and use its best
efforts  in the  conduct of an audit or other  proceeding  as  provided  by this
Section 5.2, and such failure results in the imposition of additional  Taxes for
the  period  or  periods  involved  in  the  audit  or  other  proceeding,   the
Nonperforming Party shall be liable in full for such additional Taxes.

     SECTION Retention of Records;  Access.  Beginning on the Distribution Date,
the Corporation and IMS HEALTH shall,  and shall cause each of their  Controlled
Entities to:

     retain adequate records,  documents,  accounting data and other information
(including  computer data)  necessary for the  preparation and filing of all Tax
Returns  required  to be filed by any member of the  Pre-Distribution  Cognizant
Group or any  combination  of such  members  and for any audits  and  litigation
relating  to such Tax  Returns  or to any  Taxes  payable  by any  member of the
Pre-Distribution Cognizant Group or any combination of such members; and

     give to the  other  Party  reasonable  access to such  records,  documents,
accounting  data and  other  information  (including  computer  data) and to its
personnel and  premises,  for the purpose of the review or audit of such reports
or returns to the extent relevant to an obligation or liability of a Party under
this Agreement and in accordance  with the procedures  provided in Article IV of
the Distribution Agreement. The obligations set forth in these paragraphs 5.3(a)
and 5.3(b) shall continue until the final  conclusion of any litigation to which
the  records  and  information  relate  or until  expiration  of all  applicable
statutes of limitations, whichever is longer.

established under the IMS Health Retirement Plan.

     (c) From the Effective Time until the Final IMS Health Retirement  Transfer

proportions  as such assets were  invested  immediately  prior to the  Effective
Time, which are set forth in Schedule 2.2 hereof.

     (d) As soon as practicable  after the Effective Time, the remaining  assets
allocable  to the IMS Health  Transferred  Retirement  Plan  Employees  shall be
transferred to a separate trust established under the IMS Health Retirement Plan
(such date herein referred to as the "Final IMS Health  Retirement Plan Transfer
Date"); provided, however, that in no event shall such transfer take place until
Corporation  shall make all required  amendments to the  Corporation  Retirement
Plan and related trust  agreement  necessary to provide for the  segregation and
transfer of assets described in this Section 2.2. The value of such assets to be
transferred  shall equal the value of segregated assets determined based on same
methodology as in Section 2.2(a) of this  Agreement,  reduced by an amount equal
to the Initial Transferred Assets, adjusted as follows:

          (i)  reduced  by  the  amount  of  benefit  payments  made  under  the
     Corporation   Retirement  Plan  with  respect  to  IMS  Health  Transferred
     Retirement  Plan  Employees from the Effective Time to the Final IMS Health
     Retirement Plan Transfer Date; and

          (ii)  increased  (or  decreased)  by the  share of the net  investment
     income (or loss) and expenses  incurred or for which invoices are submitted
     after the Effective  Time to the IMS Health  Retirement  Plan Transfer Date
     attributable to the value of such segregated assets.

     (e) Unless otherwise  agreed to by Corporation and IMS Health,  the form of
the assets to be transferred shall consist of an undivided  percentage  interest
in each asset that is held by the Corporation  Retirement Plan on the IMS Health
Retirement Plan Transfer Date, such undivided percentage interest being equal to
the value of assets  allocable  to the IMS Health  Transferred  Retirement  Plan
Employees, divided by the fair market value of plan assets.

     (f) If the amount of the Initial  Transferred  Assets  exceeds the value of
the  assets  to be  transferred  as  determined  under  Section  2.2(d)  of this
Agreement,  such excess amount shall promptly be transferred from the IMS Health
Retirement Plan trust to the Corporation Retirement Plan trust.

     SECTION 2.3.  Allocation of Liabilities.  The IMS Health Group shall assume
all  Liabilities  relating  to  the  participation  of  IMS  Health  Transferred

IMS Health  Retirees  who were  participants  in the  Corporation  Savings  Plan

     (b) Prior to the date on which the  transfer of assets and  liabilities  to
the IMS Health  Savings Plan shall occur (the "IMS Health  Savings Plan Transfer

Effective  Time,  Corporation  shall (A) cause the  trustee  of the  Corporation

the trustee of the  Corporation  Savings  Plan to transfer to the trustee of the
IMS Health  Savings Plan the full account  balances  (inclusive of loans) of IMS
Health  Transferred  Savings Plan  Employees  in kind based on those  investment
funds in which such  account  balances  are then  invested  (including,  but not
limited to, the pooled stock fund described in Section 3.4); provided,  however,
that loans to IMS Health Transferred Savings Plan Employees shall be transferred
in the form of notes. In consideration of the segregation and transfer of assets
described  herein,  the IMS  Health  Savings  Plan  shall,  as of the IMS Health
Savings Plan Transfer Date, assume all Liabilities  attributable to such assets,
whether  incurred prior to or after the Effective Time. If the account  balances
of the IMS  Health  Transferred  Savings  Plan that are  transferred  on the IMS
Health  Savings  Plan  Transfer  Date are  thereafter  determined  to have  been
incorrect,

the parties  agree to make  appropriate  payments or asset  transfers to correct

former  employees and covered  dependents who  participated in a plan maintained
solely for their  benefit  whether the  applicable  event occurs prior to, on or

Post-Distribution  Employee  is  entitled  as a  result  of a  qualifying  event
occurring  at or after the  Effective  Time shall be the  responsibility  of the
Corporation Group.

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

     (a)  Corporation  Post-Distribution  Employees;  and  Corporation  Disabled
Employees. From and after the Effective Time, each unexercised Corporation Stock
Option held by Corporation  Post-Distribution  Employees,  Corporation  Disabled
Employees and the specified  options held by the persons  listed on Schedule 6.1
shall remain  outstanding  pursuant to the terms of the award agreements and the
Corporation  Stock Option  Plans;  provided,  however,  that from and after such
time, each  unexercised  Corporation  Stock Option shall be adjusted as follows:
(i) the number of shares of  Corporation  Common  Stock  covered by the adjusted
stock  option shall be  determined  by (A)  multiplying  the number of shares of
Corporation  Common Stock covered by the Corporation Stock Option by a fraction,
the  numerator of which  equals the average of high and low trading  prices of a
share  of  Corporation  Common  Stock  for the  five  trading  days  immediately
preceding the ex-dividend  date, and the denominator of which equals the average
of high and low trading  prices of a share of  Corporation  Common Stock for the
five trading days starting on the ex-dividend trading Date ("Corporation Ratio")

                                                                              18


     (b) IMS Health Employees;  IMS Health  Transitional  Employees;  IMS Health
Disabled  Employees;  and Walsh  Optionees.  As of the Effective  Time, (i) each
unexercised  Corporation Stock Option held by IMS Health  Employees,  IMS Health
Transitional Employees,  IMS Health Disabled Employees and Walsh Optionees shall
be cancelled except as provided in Schedule 6.1 and (ii) such individuals  shall
except as provided in Schedule 6.1 receive  replacement  stock  options  awarded
under the IMS Health  Replacement  Plans,  which  shall be adopted by IMS Health
prior to the  Effective  Time.  The number of shares of IMS Health  Common Stock
covered by each replacement  stock option shall be determined by (i) multiplying
the  number of shares of  Corporation  Common  Stock  covered  by the  cancelled
Corporation  Stock  Option by a  fraction,  the  numerator  of which  equals the
average of high and low trading  prices of a share of  Corporation  Common Stock
for the five trading days  immediately  preceding the ex-dividend  date, and the
denominator of which equals the average of high and low trading prices of an IMS
Health  Common  Share for the five  trading  days  starting  on the  regular way
trading date ("IMS Health  Ratio") and (ii)  rounding down the result to a whole
number of shares.  The exercise price of each replacement  stock option shall be
determined  by dividing the exercise  price of the cancelled  Corporation  Stock
Option by the IMS Health ratio.  Except as otherwise  provided in the IMS Health
Replacement Plans, all other terms of the replacement stock options shall remain
substantially identical to the terms of the cancelled Corporation Stock Options.

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

     SECTION 6.2.  Corporation  LSARs.  All limited  stock  appreciation  rights
awarded under the Corporation Stock Option Plans ("Corporation  LSARs") shall be
adjusted or substituted (as the case may be) in substantially the same manner as
the Corporation Stock Options described in Section 6.1 above.

     SECTION 6.3.  Restricted  Stock Plan.  Restricted  stock  awarded under the
Corporation Stock Option Plans  ("Corporation  Restricted Stock") and restricted
stock received as a result of the Distribution  ("IMS Health Restricted  Stock")
shall be treated as follows:

     (a)  Corporation  Post-Distribution  Employees.  As of Effective  Time, IMS
Health  Restricted  Stock  credited to Corporation  Post-Distribution  Employees
shall be adjusted  pursuant to the Corporation  Stock Option Plans and each such

                                                                              19


individual shall receive a number of additional shares of Corporation Restricted
Stock,  determined by  multiplying  the number of shares of forfeited IMS Health
Restricted  Stock by the Corporation  Ratio and the reciprocal of the IMS Health
Ratio, having the same terms as the Corporation Restricted Stock from which they
arose.

     (b) IMS Health Employees.  As of the Effective Time, Corporation Restricted
Stock and IMS Health  Restricted  Stock credited to IMS Health Employees and IMS
Health  Transitional  Employees  shall be forfeited and such  individuals  shall
receive  replacement  IMS  Health  Restricted  Stock  equal to (i) the number of
shares of forfeited IMS Health  Restricted  Stock plus (ii) the number of shares
of forfeited Corporation Restricted Stock multiplied by the IMS Health Ratio and
the reciprocal of the Corporation  Ratio, such replacement  shares of IMS Health
Restricted Stock to have the same terms as the Corporation Restricted Stock from
which they arose.

     SECTION 6.4. Executive Annual Incentive Plan.  Outstanding awards under the
Corporation  Executive  Annual  Incentive Plan shall be treated as determined by
the Corporation and IMS Health, respectively.

     SECTION 6.5.  Corporation  Employee Stock Purchase Plan. (a) From and after
the  Effective  Time,  Corporation  shall  continue to sponsor  the  Corporation
Employee Stock Purchase Plan.

Employee Stock Purchase Plan for the benefit of IMS Health Employees.

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

employee plan  contributions,  (i) without  giving  effect to any  present-value

                               W I T N E S S E T H

     WHEREAS,  pursuant to a Distribution Agreement dated as of October 28, 1996
(the  "1996  Distribution  Agreement")  among  the  Corporation,  Cognizant  and
ACNielsen,   each  party  agreed  to  provide  to  the  other  parties   certain
transitional,  administrative and support services, including insurance and risk
management  services,  on the terms set  forth in the 1996  Transition  Services
Agreement and the Appendix thereto.

     WHEREAS, each of the Corporation,  Cognizant and ACNielsen desires to amend
and  restate  the  1996  Transition  Services  Agreement  as set  forth  in this
Agreement and to include New D&B, IMS Health and Gartner as parties hereto;  and
each of New D&B,  IMS  Health  and  Gartner  desires  to  become a party to this
Agreement.

     NOW,  THEREFORE,   in  consideration  of  the  agreements,   covenants  and
provisions in this  Agreement and intending to be legally bound hereby,  each of
the Corporation,  New D&B, Cognizant, IMS Health, ACNielsen and Gartner mutually
covenant and agree as follows:

                                    ARTICLE I
                                SERVICES PROVIDED

     I.1  Transition   Services.   New  D&B  (the   "Provider")   shall  provide
comprehensive  insurance  and  risk  management  services  to  the  Corporation,
Cognizant, IMS Health, ACNielsen and Gartner (each a "Recipient";  collectively,
the "Recipients"). Such services shall include risk identification,  development
of appropriate insurance programs, loss prevention  initiatives,  accounting for
premiums,   deductibles,   retentions  and  defense  costs,   claims  management
(including   coordination   with   insurance   carriers),   the  collection  and
distribution of insurance  proceeds and such other services as the Corporation's
Risk  Management  staff has been  providing 

<PAGE>

                                                                               2


to the  Corporation,  Cognizant  and  ACNielsen  as of the date hereof (all such
services, collectively, the "Transition Services").

     I.2  Personnel.  In providing the Transition  Services,  the Provider as it
deems necessary or appropriate in its sole discretion, may (i) use the personnel
of such  Provider  or its  Affiliates,  and (ii)  employ the  services  of third
parties to the extent  such third  party  services  are  routinely  utilized  to
provide similar  services to other businesses of such Provider or are reasonably
necessary for the efficient performance of any of such Transition Services. Each
Recipient  may  retain  at  its  own  expense  its  own  consultants  and  other
professional advisers.

     I.3  Representatives.  Each of the  Corporation,  New D&B,  Cognizant,  IMS
Health,  ACNielsen and Gartner  shall  nominate a  representative  to act as its
primary  contact  person for the  provision  of all of the  Transition  Services
(collectively,  the "Primary  Coordinators").  The initial Primary  Coordinators
shall be Frank Colarusso,  Treasurer, for the Corporation,  John Riley, Director
of Risk Management,  for New D&B, Stuart Goldshein,  Controller,  for Cognizant,
Matthew  Friedman,  Assistant  Treasurer,  for  IMS  Health,  John  Forster  for
ACNielsen  and  Andrea  Tarbox  for  Gartner.  Each  party may treat an act of a
Primary  Coordinator  of another  party as being  authorized by such other party
without  inquiring  behind  such  act  or  ascertaining   whether  such  Primary
Coordinator had authority to so act. The Provider and the relevant  Recipient of
a  Transition  Service  shall  advise each other in writing of any change in the
Primary Coordinators for such Transition Service,  setting forth the name of the
Primary  Coordinator  to be  replaced  and  the  name  of the  replacement,  and
certifying  that the  replacement  Primary  Coordinator is authorized to act for
such party in all matters  relating to this Agreement.  Each of the Corporation,
New  D&B,  Cognizant,   IMS  Health,   ACNielsen  and  Gartner  agree  that  all
communications  relating to the provision of the  Transition  Services  shall be
directed to the Primary Coordinators.

     I.4 Level of  Transition  Services.  (a) The  Provider  shall  perform  the
Transition  Services for which it is responsible  hereunder  following  commonly
accepted  standards of care in the industry  and  exercising  the same degree of
care as it  exercises  in  performing  the same or similar  services for its own
account as of the date of this  Agreement,  with priority equal to that provided
to its  own  businesses  or  those  of any of its  Affiliates,  Subsidiaries  or
divisions.  Nothing in this  Agreement  shall  require the Provider to favor the
businesses  of any  Recipient  over  its own  businesses  or those of any of its
Affiliates, Subsidiaries or divisions.

     (b) The  Provider  shall not be required to provide any  Recipient  of such
Transition Services with extraordinary  levels of Transition  Services,  special
studies,  training,  or  the  like  or  the  advantage  of  systems,  equipment,
facilities,  training,  or  improvements  procured,  obtained  or  made  by  the
Provider.

     (c) In  addition  to being  subject  to the  terms and  conditions  of this
Agreement for the provision of the Transition  Services,  each Recipient  agrees
that the Transition  Services  

<PAGE>

                                                                               3


provided by third  parties  shall be subject to the terms and  conditions of any
agreements  between the Provider  and such third  parties.  The  Provider  shall
consult with the relevant  Recipient  concerning the terms and conditions of any
such  agreements to be entered into, or proposed to be entered into,  with third
parties after the date hereof.

     I.5 Limitation of Liability.  In the absence of gross negligence or willful
misconduct  on the part of the  Provider,  and  whether or not the  Provider  is
negligent,  such  Provider  shall not be  liable  for any  claims,  liabilities,
damages,  losses, costs,  expenses (including,  but not limited to, settlements,
judgments,  court costs and reasonable  attorneys'  fees),  fines and penalties,
arising  out of any  actual or  alleged  injury,  loss or  damage of any  nature
whatsoever in providing or failing to provide  Transition  Services for which it
is  responsible   hereunder  to  the  Recipient  of  such  Transition  Services.
Notwithstanding  anything to the  contrary  contained  herein,  in the event the
Provider  commits an error with respect to or  incorrectly  performs or fails to
perform  any  Transition  Service,  at the  relevant  Recipient's  request,  the
Provider  shall use  reasonable  efforts  and good faith to correct  such error,
re-perform  or perform such  Transition  Service at no  additional  cost to such
Recipient;  provided, that the Provider shall have no obligation to recreate any
lost  or  destroyed  data  to  the  extent  the  same  cannot  be  cured  by the
re-performance of the Transition Service in question.

     I.6 Force Majeure. Any failure or omission by a party in the performance of
any  obligation  under  this  Agreement  shall  not be  deemed a breach  of this
Agreement or create any  liability,  if the same arises from any cause or causes
beyond the control of such party, including,  but not limited to, the following,
which, for purposes of this Agreement shall be regarded as beyond the control of
each of the  parties  hereto:  acts  of God,  fire,  storm,  flood,  earthquake,
governmental regulation or direction,  acts of the public enemy, war, rebellion,
insurrection,  riot, invasion, strike or lockout;  provided,  however, that such
party  shall  resume  the   performance   whenever   such  causes  are  removed.
Notwithstanding the foregoing, if such party cannot perform under this Agreement
for a period of forty-five  (45) days due to such cause or causes,  the affected
party may terminate the Agreement with the defaulting party by providing written
notice thereto.

     I.7 Modification of Procedures.  The Provider may make changes from time to
time in its standards and procedures for performing the Transition  Services for
which it is  responsible  hereunder.  Notwithstanding  the  foregoing  sentence,
unless required by law, the Provider shall not implement any substantial changes
affecting a Recipient of the relevant Transition Services unless:

          (a) the Provider has furnished such  Recipient  notice (which shall be
     the same notice the Provider shall provide its own businesses) thereof;

          (b) the Provider changes such procedures for its own businesses at the
     same time; and

                                                                               4


          (c) the Provider gives such Recipient a reasonable  period of time for
     such Recipient (i) to adapt its  operations to accommodate  such changes or
     (ii) to reject the proposed  changes.  In the event such Recipient fails to
     accept or reject a proposed  change on or before a date  specified  in such
     notice of change,  such  Recipient  shall be deemed to have  accepted  such
     change.  In the event such Recipient rejects a proposed change but does not
     terminate  this  Agreement,  such  Recipient  agrees  to  pay  any  charges
     resulting from the Provider's  need to maintain  different  versions of the
     same  systems,  procedures,  technologies,  or services or  resulting  from
     requirements of third party vendors or suppliers.

     I.8 No Obligation to Continue to Use Services.  No Recipient shall have any
obligation  to continue to use the  Transition  Services and may  terminate  the
Transition  Services that the Provider is providing to such  Recipient by giving
the Provider 180 days notice thereof.

     I.9 Provider Access. To the extent reasonably required for personnel of the
Provider  to  perform  the  Transition   Services  for  which  the  Provider  is
responsible  hereunder,  the Recipient of such Transition Services shall provide
personnel of the Provider with access to its  equipment,  office space,  plants,
telecommunications  and computer equipment and systems,  and any other areas and
equipment.

     I.10 Performance Reviews. The Primary Coordinators for each Recipient shall
meet  during  the  fourth  quarter  of  each  calendar  year  with  the  Primary
Coordinator for the Provider for the purpose of reviewing the performance of the
Provider's Risk Management  staff. Any disputes  relating to the quality of such
performance  shall be brought to the attention of the respective Chief Financial
Officers  (or  person  holding  an  equivalent  title) of the  Provider  and the
Recipients.

                                                                               5


     II.1  Consideration.  As consideration  for the Transition  Services,  each
Recipient  of  Transition  Services  shall pay to the  Provider a portion of the
costs and  expenses  incurred by the  Provider  relating to the Risk  Management
staff as follows: each Recipient shall pay (i) a base charge of $50,000 per year
plus (ii) a proportionate  share of any additional costs and expenses (i.e., not
covered by the total base charge) based on such Recipient's  proportion of total
revenue as a percentage  of the  aggregate  total revenue of all parties to this
Agreement. For purposes of calculating any additional amount payable pursuant to
clause (ii) of the preceding sentence, a party's revenue shall be that set forth
on its audited  financial  statements for the most recent fiscal year-end.  Such
costs and expenses  shall be calculated in accordance  with  generally  accepted
accounting   principles  applied  consistently  and  billed  in  twelve  monthly
installments.  Notwithstanding the foregoing,  however, any services provided by
the Provider's Risk Management  staff to the Provider or the Recipients that are
not in the ordinary  course (all such services being  "extraordinary  services")
shall be borne by the company or companies for whom such  extraordinary  service
was provided.  No  extraordinary  service shall be provided without the specific
approval  of the company to be  charged.  The costs and  expenses to be borne by
each Recipient will be in accordance with the annual Risk  Management  budget to
be provided by the Primary  Coordinator  for the Provider  during the  preceding
calendar  year by May 1 of each year.  The Risk  Management  budget may increase
each year in an amount  equal to 5% over the prior year's  budget;  increases in
excess of 5% must be approved by the respective  Primary  Coordinators  for each
Recipient.

     II.2 Invoices. After the end of each month, the Provider, together with its
Affiliates or Subsidiaries providing Transition Services will submit one invoice
to the  Recipient  of  such  Transition  Services  for all  Transition  Services
provided to such  Recipient  and its  Subsidiaries  by the Provider  during such
month.  Such monthly invoices shall be issued no later than the fifteenth day of
each  succeeding  month.  Each  invoice  shall  include  a  summary  list of the
previously agreed upon Transition Service for which there are fixed dollar fees,
together with documentation supporting each of the invoiced amounts that are not
covered by the fixed fee agreements.  The total amount set forth on such summary
list and such  supporting  detail  shall  equal the invoice  total,  and will be
provided under separate cover apart from the invoice. All invoices shall be sent
to the attention of the Primary  Coordinator of the applicable  Recipient at the
address  set forth in  Section  6.5  hereof  or to such  other  address  as such
Recipient shall have specified by notice in writing to the Provider.

     II.3  Payment  of  Invoices.  (a)  Payment  of all  invoices  in respect of
Transition  Services shall be made by check or electronic funds  transmission in
U.S. Dollars,  without any offset or deduction of any nature whatsoever,  within
thirty (30) days of the invoice date.  All payments shall be made to the account
designated by the Provider to the relevant Recipient,  with written confirmation
of  payment  sent by  facsimile  to the  Primary  Coordinator  or  other  person
designated thereby.

     (b) If any payment is not paid when due, the Provider shall have the right,
without  any  liability  to any  Recipient  of  Transition  Services,  or anyone
claiming  by or  through  such  Recipient,  upon  five  days'  notice,  to cease
providing any or all of the Transition Services provided by the Provider to such
Recipient, which right may be exercised by the Provider in its sole and absolute
discretion.

                                   ARTICLE III
                                 CONFIDENTIALITY

     III.1 Obligation.  Each party and its Subsidiaries  shall not use or permit
the use of (without the prior  written  consent of the other  parties) and shall
keep, and shall cause its  consultants  and advisors to keep,  confidential  all
information  concerning the other parties received  pursuant to or in connection
with this  Agreement.  Additionally,  any  information  which is identified by a
party as being "highly sensitive" (in connection with a contemplated acquisition
or otherwise)  shall not be disclosed  outside of the Provider's Risk Management
staff.

     III.2 Care and  Inadvertent  Disclosure.  With respect to any  confidential
information, each party agrees as follows:

          (a) it  shall  use  the  same  degree  of care  in  safeguarding  said
     information as it uses to safeguard its own information  which must be held
     in confidence; and

          (b) upon the discovery of any  inadvertent  disclosure or unauthorized
     use of said  information,  or upon obtaining notice of such a disclosure or
     use from any other party,  it shall take all  necessary  actions to prevent
     any further inadvertent disclosure or unauthorized use, and, subject to the
     provisions of Section 1.5 above, each such other party shall be entitled to
     pursue any other remedy which may be available to it.

                              TERM AND TERMINATION

     IV.1 Term. This Agreement shall become effective on June 30, 1998 and shall
remain in force for a period of three  years (or in the case of  ACNielsen,  IMS
Health and Gartner  until  November 1, 1999).  After such initial  period,  this
Agreement shall  automatically be renewed for successive  one-year periods as to
each party  unless  such party  provides at least  180-days  notice to the other
parties of its  intention  not to renew;  provided  that this  Agreement  may be
terminated at such other times as are set forth in Sections 1.6, 1.8 and 4.3.

     IV.3 Default.  If any party (hereafter called the "Defaulting Party") shall
fail to perform or default in the  performance of any of its  obligations  under
this Agreement (other than a payment default), the party entitled to the benefit
of such performance  (hereinafter  referred to as a "Non-Defaulting  Party") may
give  written  notice to the  Defaulting  Party  specifying  the  nature of such
failure  or  default  and  stating  that the  Non-Defaulting  Party  intends  to
terminate this Agreement with respect to the Defaulting Party if such failure or
default is not cured within fifteen days of such written notice.  If any failure
or default so  specified  is not cured  within  such  fifteen  day  period,  the
Non-Defaulting  Party may elect to  immediately  terminate  this  Agreement with
respect to the  Defaulting  Party;  provided,  however,  that if the  failure or
default  relates to a dispute  contested in good faith by the Defaulting  Party,
the Non-Defaulting Party may not terminate this Agreement pending the resolution
of such dispute in accordance with Article V hereof.  Such termination  shall be
effective upon giving a written notice of  termination  from the  Non-Defaulting
Party to the Defaulting Party and shall be without prejudice to any other remedy
which may be available to the Non-Defaulting Party against the Defaulting Party.

     IV.4  Termination of Obligations.  Each Recipient  specifically  agrees and
acknowledges  that all  obligations  of the  Provider to provide the  Transition
Services  shall  immediately  cease,  with respect to such  Recipient,  upon the
termination  of this Agreement as to such  Recipient.  Upon the cessation of the
Provider's  obligation to provide any  Transition  Service to a Recipient,  such
Recipient shall immediately cease using, directly or indirectly,  the Transition
Services (including, without limitation, any and all software of the Provider or
third party software provided through the Provider,  telecommunications services
or equipment, or computer systems or equipment).

     IV.5 Survival of Certain Obligations.  Without prejudice to the survival of
the other agreements of the parties, Sections 1.5, 2.1 (with respect to services
provided  prior to the effective time of the  termination),  3.1, 3.2, 4.4, 4.5,
5.1, 6.10, 6.13 and 6.14 shall survive any termination of this Agreement.

mechanisms set forth in Article VI of the 1996 Distribution Agreement, with each
of the parties hereto being deemed a party to that agreement for this purpose.

increasing the value of the Shares on a long-term basis.

Option may  thereafter  be  exercised,  during the shorter of (i) the  remaining
stated  term of the  Option or (ii) the  period  that is the  longer of (A) five
years  after the date of such  termination  of service or (B) one year after the

upon such terms and  conditions  as may be  specified  by the  Committee  in the
related Award agreement(s).

     (c) Acceleration. Notwithstanding anything in the Plan to the contrary, (i)
the  restrictions  set forth in  Section  7(b) of the Plan  shall  automatically
elapse in the event that a Participant  terminates service with the Company as a
result of death or  Disability  and (ii) the  Committee  (excluding  any  member
thereof  whose  own  Award  is at  issue  in a  given  case)  may,  in its  sole
discretion,  accelerate  the elapsing of the  restrictions  set forth in Section
7(b) of the Plan in the event that a  Participant  terminates  service  with the
Company for any other reason. In the absence of such acceleration, all Shares of
Restricted Stock as to which  restrictions have not previously  elapsed pursuant
to  Section  7(b) of the Plan  shall be  forfeited  upon  the  termination  of a
Participant's  service  with  the  Company  for  reasons  other  than  death  or
Disability.

the  Effective  Date by reason of any Share  dividend or split,  reorganization,
recapitalization,  merger, consolidation,  spin-off,  combination or exchange of
Shares or other  corporate  exchange,  or any  distribution  to  stockholders of
Shares other than regular cash  dividends,  the Committee in its sole discretion
and without liability to any person may make such substitution or adjustment, if
any,  as it 

<PAGE>

                                                                               8


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 and/or (iii) any other affected terms
of such Awards.

     (b) Change in Control.  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.


9.   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.


10.  Amendments or Termination

     The Board may  amend,  alter or  discontinue  the Plan,  but no  amendment,
alteration or discontinuation shall be made which would impair the rights of any
Participant  under any Award  theretofore  granted  without  such  Participant's
consent.


11.  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 11 (or any
part  thereof) to the extent that this  Section 11 (or any part  thereof) is not
required  under  the  rules  promulgated  under  any  law,  rule  or  regulation
applicable to the Company.

                                                                               5


conclusive and binding on all parties concerned (including,  but not limited to,
Participants and their beneficiaries or successors).


4.   Eligibility

     All Participants shall be eligible to participate under this Plan.


5.   Voluntary Deferral of Cash Compensation

     A Participant may voluntarily  elect to defer his or her cash  compensation
(including,  but not limited to, annual retainer,  board meeting fees, committee
meeting fees and committee chairman fees) in the following manner:

          (a) Method of Election. In order to make a voluntary election pursuant
     to the Plan, the Participant  must complete and deliver to the Secretary of
     the  Company a written  election,  not later than 30 days after the date on
     which he or she  commences  service as a director  of the  Company  (or, in
     subsequent years, not later than the anniversary of the normal commencement
     date for such director's  term),  designating (i) the portion of his or her
     cash  compensation  for a year  of  service  as a  director  that  is to be
     deferred (the "Annual Deferral  Amount") and (ii) the portion of the Annual
     Deferral Amount that is to be deferred into (A) Deferred Share Units and/or
     (B) Deferred Cash. Such an election shall only be effective with respect to
     (i) the annual  retainer  and (ii) any other fees earned  after the date of
     the election.  Such election shall remain effective for all future years of
     service unless the Participant makes a new election in a subsequent year.

          (b) Deferred Share Units. If a Participant  elects to defer his or her
     Annual Deferral  Amount into Deferred Share Units,  such  Participant  will
     have  Deferred  Share Units  credited  (as of each date on which his or her
     cash compensation  would otherwise have been paid) to a Deferred Share Unit
     account  maintained for him or her on the books of the Company.  The number
     of Deferred Share Units (including  fractional  Deferred Share Units) to be
     credited   shall  be   determined  by  dividing  (i)  the  amount  of  cash
     compensation  to be  deferred  into  Deferred  Share Units by (ii) the Fair
     Market Value of one Share on the date credited.  Deferred Share Units shall
     be credited with dividend  equivalents  when  dividends are paid on Shares,
     and such dividend  equivalents shall be converted into additional  Deferred
     Share Units based on the Fair Market Value of Shares on the date  credited.
     Notwithstanding  anything to the  contrary in this Section  5(b),  the Fair
     Market Value of one Share on any date prior to the First Trading Date shall
     be the Fair Market Value of one Share on the First Trading Date.

<PAGE>

                                                                               6


          (c) Deferred  Cash.  If a  Participant  makes a voluntary  election to
     defer  his  or  her  Annual   Deferral  Amount  into  Deferred  Cash,  such
     Participant  will have Deferred Cash credited (as of each date on which his
     or her cash compensation would otherwise have been paid) to a Deferred Cash
     account  maintained for him or her on the books of the Company.  The amount
     of Deferred Cash to be credited shall equal the amount of cash compensation
     to be  deferred  into  Deferred  Cash.  A  Participant's  account  shall be
     credited  with  additional  Deferred  Cash equal to the amount of  notional
     interest  earned on the account,  assuming  that such interest is earned at
     the Prime Rate and compounded on an annual basis.


6.   Termination of Board Service

     No later  than the first  business  day of the  calendar  year  immediately
following  the date on which a Participant  terminates  service with the Company
(the "Determination Date"), the Participant shall receive (a) a lump sum payment
in  Shares  equal  in  number  to  the  Deferred  Share  Units  credited  to the
Participant's   Deferred  Share  Unit  account  (provided,   however,  that  any
fractional  Shares  shall be paid in cash  based on the Fair  Market  Value of a
Share as of the Determination  Date) and (b) a lump sum payment in cash equal to
the Deferred Cash credited to the Participant's Deferred Cash account.


7.   Nontransferability of Units

     Awards 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,  Awards shall be payable only to such Participant. Awards payable
after  the  death  of a  Participant  may  be  paid  to the  legatees,  personal
representatives or distributees of the Participant.


8.   Unfunded Plan

     Unless otherwise  determined by the Committee,  the Plan shall be unfunded.
To the extent  any  individual  holds any  rights by virtue of an Award  granted
under the Plan, such rights (unless otherwise determined by the Committee) shall
be no greater than the rights of an unsecured general creditor of the Company.


9.   Adjustments Upon Certain Events

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

                                                                               7


          (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 or other  corporate  exchange,  or any
     distribution  to  stockholders of Shares other than regular cash dividends,
     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 any Deferred Share Units granted under the Plan.

          (b)  Change  in  Control.  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 Awards  (including,  without  limitation,  (i) the  acceleration  of
     Awards,  (ii) the payment of a cash amount in exchange for the cancellation
     of Awards 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.


10.  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.


11.  Amendments or Termination

     The Board may  amend,  alter or  discontinue  the Plan,  but no  amendment,
alteration or discontinuation shall be made which would impair the rights of any
Participant  under any Awards  theretofore  granted  without such  Participant's
consent.


12.  Choice of Law

     The Plan shall be governed by and construed in accordance  with the laws of
the State of New York  applicable  to contracts  made and to be performed in the
State of New York.


13.  Effectiveness of the Plan

     The Plan shall be effective as of the Spinoff Date.





                                                                    Exhibit 10.7

     (w)  Shares:  Shares of common  stock,  par value  $0.01 per Share,  of the
Company.

     (x) Spinoff Date:  The date on which the Shares that are owned by Cognizant
are distributed to the holders of record of shares of Cognizant.

     (y) Stock  Appreciation  Right: A stock appreciation right granted pursuant
to Section 8 of the Plan.

     (z) Subsidiary:  A subsidiary corporation,  as defined in Section 424(f) of
the Code (or any successor section thereto).

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.  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 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 


                                       4
<PAGE>

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

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

5.   Eligibility


                                       5
<PAGE>

     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,  unless
otherwise determined by the Committee

     (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) 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 


                                       6
<PAGE>

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)  Termination   Provisions.   The  Committee  shall  determine,  in  its
discretion,  whether  and the extent to which an Option  shall be  forfeited  or
shall  become   exercisable  on  an  accelerated  basis  in  the  event  of  the
Participant's termination of employment due to death, Disability, Retirement, or
for other  reasons,  the period  following  such a termination  during which the
Option shall be exercisable, and other provisions relating to such terminations.

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  


                                       7
<PAGE>

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.

     (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  


                                       8
<PAGE>

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 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


                                       9
<PAGE>

     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  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


                                       10
<PAGE>

     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 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
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; (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;  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


                                       11
<PAGE>

     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.

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.

1.   Purpose of the Plan

     The  purpose  of the  1998 IMS  Health  Incorporated  Replacement  Plan for
Certain Employees Holding Cognizant Corporation Equity-Based Awards (the "Plan")
is to  provide  for the  award  of  substantially  identical  replacement  stock
options,   replacement   limited  stock  appreciation   rights  and  replacement
restricted  stock to certain  employees (the  "Eligible  Holders") of IMS Health
Incorporated  (the "Company") whose awards under the 1996 Cognizant  Corporation
Key Employees  Stock Incentive Plan and 1996 Cognizant  Corporation  Replacement
Plan for Certain Employees Holding The Dun & Bradstreet Corporation Equity-Based
Awards (the  "Cognizant  Plans") were  cancelled  pursuant to the spinoff of the
Company from Cognizant Corporation  ("Cognizant").  The Company expects that the
Plan will allow it to retain such  employees and to motivate them to exert their
best  efforts  on  behalf  of the  Company  and its  subsidiaries  by  providing
incentives through the replacement awards. The Company also 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.
It is the intention of the Company that the terms of the replacement awards will
(i) preserve  the  economic  value of the  cancelled  Cognizant  awards and (ii)
except for the terms  described in Sections 7, 8, 9 and 10 of this Plan,  remain
substantially identical to the terms of the cancelled Cognizant awards.

     The total  number of Shares  which may be issued under the Plan is equal to
the aggregate  number of shares  subject to  replacement  awards,  as calculated
pursuant to Sections 7(a),  8(a) and 9 of this Plan. The Shares may consist,  in
whole or in part, of unissued shares or treasury shares. Issuance of Shares upon
exercise of an option or reduction of the number of Shares  subject to an option
upon  exercise of a stock  appreciation  right shall  reduce the total number of
Shares  available  under the Plan.  In  addition,  Shares  which are  subject to
unexercised  stock  options which  terminate or lapse may not be optioned  again
under the Plan.

4.   Administration

     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 


<PAGE>
                                                                               6


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, Eligible  Holders and their  beneficiaries  or successors).  The
Committee  shall require  payment of any amount it may determine to be necessary
to withhold for federal, state, local or other taxes as a result of the exercise
of an Award. Unless the Committee specifies  otherwise,  the Eligible Holder 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 Eligible  Holder.  The number of Shares so
delivered or withheld  shall have an aggregate  Fair Market Value  sufficient to
satisfy the applicable withholding taxes.

5.   Eligibility

     Only Eligible  Holders shall receive grants of  replacement  stock options,
replacement stock appreciation rights and replacement restricted stock under the
Plan.  The granting of a stock option,  stock  appreciation  right or restricted
stock under the Plan shall impose no obligation on the Company or any Subsidiary
to continue the employment of an Eligible  Holder and shall not lessen or affect
the right to terminate the employment of such Eligible Holder.

6.   Limitations

     Options  hereunder  shall only be granted in replacement of Cognizant Stock
Options  (as  defined in  Section  7(a) of the Plan)  held by  Eligible  Holders
immediately prior to the Spinoff Date.

7.   Terms and Conditions of Options

     Stock options granted under the Plan shall be  non-qualified,  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) Generally.  As of the Spinoff Date, each unexercised  stock option
     held by an Eligible  Holder that was granted under the  Cognizant  Plans (a
     "Cognizant  Stock  Option")  shall be cancelled,  and such Eligible  Holder
     shall receive a replacement  stock option pursuant to this Plan. The number
     of Shares covered by each  replacement  stock option shall be determined by
     (i) multiplying  the number of shares of Cognizant  common stock covered by
     the cancelled Cognizant Stock Option by a 

<PAGE>
                                                                               7


     fraction,  the  numerator  of which is the  average  of the  Daily  Average
     Trading Prices of Cognizant common stock for the five  consecutive  trading
     days  immediately  preceding the first date on which Cognizant common stock
     is traded  ex-dividend,  and the denominator of which is the average of the
     Daily Average Trading Prices of the Shares for the five consecutive trading
     days starting on the first date on which the Shares are traded  regular way
     (the "IMS  Health  Ratio")  and (ii)  rounding  down the  result to a whole
     number of shares.  The option price of each replacement  stock option shall
     be determined by dividing the option price of the cancelled Cognizant Stock
     Option by the IMS Health Ratio.  Unless  otherwise  specified in this Plan,
     all other terms of the replacement stock options shall remain substantially
     identical to those of the cancelled Cognizant Stock Options as set forth in
     the applicable Cognizant Plan and related option agreement(s).

          (b)  Exercisability.  Except as set forth in the Plan,  stock  options
     granted under the Plan shall have substantially identical terms as those of
     the stock options originally  granted under the Cognizant Plans;  provided,
     however,  that in no event shall a replacement  stock option be exercisable
     more than ten years after the date the  original  option was granted  under
     the Cognizant Plans.

          (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) in the following sentence. The purchase price for the Shares
     as to which an Option is exercised  shall be paid to the Company in full at
     the time of exercise at the  election of the  Eligible  Holder (i) in cash,
     (ii) in Shares  having a Fair Market  Value equal to the  aggregate  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.  No Eligible  Holder shall have any
     rights to dividends or other rights of a stockholder with respect to Shares
     subject to an Option until the Eligible  Holder 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)  Exercisability  of a  Cognizant  Replacement  Stock  Option  Upon
     Termination of Employment by Death or Disability.  If an Eligible  Holder's
     employment  with the Company and its  Subsidiaries  terminates by reason of
     death or  Disability  after  


<PAGE>
                                                                               8


     the  date  of  grant  of a  Cognizant  Replacement  Stock  Option,  (i) the
     unexercised  portion of such option shall immediately vest in full and (ii)
     such  portion may  thereafter  be  exercised  during the shorter of (A) the
     remaining  stated  term of such  option or (B) five years after the date of
     death or Disability.

          (e)  Exercisability of a D&B Replacement Stock Option Upon Termination
     of  Employment by Death.  If an  optionee's  employment by the Company or a
     subsidiary terminates by reason of death one year or more after the date of
     grant of the original stock option under the D&B Plans, the D&B Replacement
     Stock Option thereafter may be exercised,  during the three years after the
     date of death or the  remaining  stated  period of such  option,  whichever
     period is shorter,  to the extent to which such option was  exercisable  at
     the  time of  death or  thereafter  would  become  exercisable  during  the
     three-year period after the date of death in accordance with its terms.

          (f)  Exercisability  of a  Cognizant  Replacement  Stock  Option  Upon
     Termination of Employment by Retirement. If an Eligible Holder's employment
     with the Company and its  Subsidiaries  terminates  by reason of Retirement
     after  the  date of grant  of a  Cognizant  Replacement  Stock  Option,  an
     unexercised  Cognizant Replacement Stock Option may thereafter be exercised
     during the shorter of (i) the remaining  stated term of such option or (ii)
     five  years  after  the  date  of  such   termination  of  employment  (the
     "Post-Retirement  Exercise  Period"),  but only to the extent to which such
     option was  exercisable  at the time of such  termination  of employment or
     becomes exercisable during the Post-Retirement  Exercise Period;  provided,
     however,  that if an  Eligible  Holder  dies  within a period of five years
     after such termination of employment,  an unexercised Cognizant Replacement
     Stock Option may  thereafter  be  exercised,  during the shorter of (i) the
     remaining  stated term of such option or (ii) the period that is the longer
     of (A) five years after the date of such  termination  of employment or (B)
     one year after the date of death (the "Special Exercise Period"),  but only
     to the extent to which  such  option  was  exercisable  at the time of such
     termination  of  employment  or  becomes  exercisable  during  the  Special
     Exercise Period. For purposes of this Section 7(f), "Retirement" shall mean
     termination  of  employment  with the  Company or a  Subsidiary  after such
     Eligible  Holder has  attained  age 55 and five  years of service  with the
     Company;  or, with the prior  written  consent of the  Committee  that such
     termination be treated as a Retirement hereunder, termination of employment
     under other circumstances.

          (g)  Exercisability of a D&B Replacement Stock Option Upon Termination
     of Employment by Disability or Retirement.  If an optionee's  employment by
     the  Company  or  a  subsidiary  terminates  by  reason  of  Disability  or
     Retirement  one year or more after the date of grant of the original  stock
     option under the D&B Plans, the D&B Replacement Stock Option thereafter may
     be exercised,  during the five years after the date of such  termination of
     employment or the remaining stated period of such 

<PAGE>
                                                                               9


     option, whichever period is shorter, to the extent to which such option was
     exercisable  at the time of such  termination  of  employment or thereafter
     would become  exercisable  during such period in accordance with its terms;
     provided,  however, that if the optionee dies within a period of five years
     after such termination of employment,  any unexercised  stock option may be
     exercised  thereafter,  during either (1) the period ending on the later of
     (i) five years after such termination of employment and (ii) one year after
     the date of death or (2) the period  remaining  in the  stated  term of the
     option, whichever period is shorter, to the extent to which such option was
     exercisable  at the time of death or  thereafter  would become  exercisable
     during the  remainder of the  five-year  period after such  termination  of
     employment in accordance with its terms. For purposes of this Section 7(f),
     "Retirement"  shall mean  termination  of employment  with the Company or a
     subsidiary after the optionee has attained age 55 and completed ten or more
     years of employment with D&B and/or the Company;  or after the optionee has
     attained age 65,  regardless  of the length of such  optionee's  employment
     with D&B and/or the Company.

          (h) Effect of Other Termination of Employment. If an Eligible Holder'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,  an  unexercised  Cognizant  Replacement  Stock
     Option may  thereafter be exercised  during the period ending 90 days after
     the date of such termination of employment, but only to the extent to which
     such Option was exercisable at the time of such  termination of employment.
     If an Eligible Holder's  employment  terminates for any reason,  other than
     Disability, death or Retirement one year or more after the date of grant of
     the original stock option under the D&B Plans as described above,  each D&B
     Replacement  Stock  Option held by such  Eligible  Holder  shall  thereupon
     terminate.  Notwithstanding  the foregoing,  the Committee may, in its sole
     discretion,  accelerate the vesting of unvested Cognizant Replacement Stock
     Options held by an Eligible  Holder if such  Eligible  Holder 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

     Stock appreciation  rights (including  limited stock  appreciation  rights)
granted under the Plan 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) Replacement  Stock  Appreciation  Rights.  As of the Spinoff Date,
     each  unexercised  stock  appreciation  right  (including  a limited  stock
     appreciation  right) held by an Eligible  Holder that was granted under the
     Cognizant Plans (a "Cognizant  SAR") shall be cancelled,  and such Eligible
     Holder 

<PAGE>
                                                                              10


     shall receive a replacement stock appreciation right pursuant to this Plan.
     The number of Company stock appreciation rights covered by each replacement
     stock  appreciation right shall be determined by (i) multiplying the number
     of Cognizant  Stock Options  covered by the cancelled  Cognizant SAR by the
     IMS Health  Ratio and (ii)  rounding  down the result to a whole  number of
     stock  appreciation  rights.  The exercise price of each replacement  stock
     appreciation  right shall be determined  by dividing the exercise  price of
     the  cancelled  Cognizant  SAR by the IMS Health  Ratio.  Unless  otherwise
     specified  in  this  Plan,  all  other  terms  of  the  replacement   stock
     appreciation  rights shall remain  substantially  identical to those of the
     cancelled Cognizant SARs as set forth in the applicable Cognizant Plans and
     related Cognizant SAR agreement(s).

          (b) Terms.  Stock  appreciation  rights  shall  cover the same  Shares
     covered  by a  related  option  (or such  lesser  number  of  Shares as the
     Committee  may  determine)  and  shall be  subject  to the same  terms  and
     conditions  as the option  except for such  additional  limitations  as are
     contemplated  by  this  Paragraph  8 (or  as  may be  included  in a  stock
     appreciation right granted hereunder).  Each stock appreciation right shall
     entitle an optionee to surrender to the Company an unexercised  option,  or
     any portion thereof,  and to receive from the Company in exchange  therefor
     an amount equal to the excess of the fair market value on the exercise date
     of one Share  over the  option  price per share  times 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.

          (c)  Limitations on  Exercisability.  The Committee  shall impose such
     conditions upon the  exercisability  of stock  appreciation  rights as will
     result,  except upon the occurrence of an event contemplated by replacement
     limited stock  appreciation  rights granted pursuant to this Paragraph 8 or
     contemplated by the provisions of Paragraph 10, in the amount to be charged
     against the Company's  consolidated  income by reason of stock appreciation
     rights  not to  exceed,  in any  one  calendar  year,  two  percent  of the
     Company's  prior calendar year's  consolidated  income before income taxes.
     The Committee also may impose,  in its  discretion,  such other  conditions
     upon the exercisability of stock appreciation rights as it may deem fit.

                                                                              11


          (d) Replacement Limited Stock Appreciation Rights. The Committee shall
     grant replacement  limited stock  appreciation  rights in substantially the
     same  manner in which  replacement  stock  appreciation  rights are awarded
     pursuant  to this  Section  8 of the Plan.  Unless  the  context  otherwise
     requires, whenever the term "stock appreciation right" is used in the Plan,
     such term shall include limited stock appreciation rights.

9.   Terms and Conditions of Restricted Stock

     As  of  the  Spinoff  Date,  Cognizant  Restricted  Stock  and  IMS  Health
Restricted  Stock  held by an  Eligible  Holder  shall  be  forfeited,  and such
Eligible  Holder shall receive  replacement  restricted  stock  pursuant to this
Plan.  The number of shares of  restricted  stock  shall equal (i) the number of
Shares of forfeited IMS Health  Restricted  Stock plus (ii) the number of shares
of forfeited Cognizant Restricted Stock multiplied by a fraction,  the numerator
of which is the average of the Daily Average Trading Prices of Cognizant  common
stock for the five consecutive  trading days starting on the ex-dividend trading
date, and the  denominator of which is the average of the Daily Average  Trading
Prices of the Shares for the five consecutive trading days starting on the first
date on which the Shares are traded regular way. Unless  otherwise  specified in
this Plan,  all other terms of the  replacement  restricted  stock shall  remain
substantially  identical to those of the forfeited Cognizant Restricted Stock as
set forth in the applicable  Cognizant  Plans and related  Cognizant  Restricted
Stock agreement(s).

                                                                              12


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 or other  corporate  exchange,  or any
     distribution  to  stockholders of Shares other than regular cash dividends,
     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 and/or (iii) any other affected
     terms of such Awards.

          (b)  Change in  Control.  Except  as  otherwise  provided  in an Award
     agreement or, with respect to D&B Replacement Options in the 1996 Cognizant
     Corporation  Replacement  Plan  for  Certain  Employees  Holding  The Dun &
     Bradstreet  Corporation  Equity-Based  Awards,  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.  Successors and Assigns

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

                                                                              13


Nontransferability of Awards

     An Award shall not be  transferable  or assignable  by the Eligible  Holder
otherwise  than by will or by the laws of descent and  distribution.  During the
lifetime  of an Eligible  Holder,  an Award  shall be  exercisable  only by such
Eligible Holder.  An Award exercisable after the death of an Eligible Holder may
be exercised by the legatees,  personal  representatives  or distributees of the
Eligible Holder. Notwithstanding anything to the contrary herein, the Committee,
in its sole  discretion,  shall have the  authority to waive this Section 12 (or
any part  thereof) to the extent that this  Section 12 (or any part  thereof) is
not  required  under the rules  promulgated  under any law,  rule or  regulation
applicable to the Company.

13.  Amendments or Termination

     The Board may  amend,  alter or  discontinue  the Plan,  but no  amendment,
alteration or  discontinuation  shall be made which, (a) without the approval of
the  stockholders of the Company,  would (except as is provided in Section 10 of
the Plan),  increase the total number of Shares reserved for the purposes of the
Plan or change the maximum  number of Shares for which  Awards may be granted to
any  Eligible  Holder or (b) without the  consent of an Eligible  Holder,  would
impair any of the rights or obligations under any Award  theretofore  granted to
such Eligible  Holder under the Plan.  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.

14.  International Eligible Holders

     With  respect to  Eligible  Holders  who reside or work  outside the United
States of  America  and who are not (and who are not  expected  to be)  "covered
employees"  within the meaning of Section 162(m) of the Code, the Committee may,
in its sole  discretion,  amend the terms of the Plan or Awards with  respect to
such Eligible  Holders in order to conform such terms with the  requirements  of
local law.

15.  Choice of Law

     The Plan shall be governed by and construed in accordance  with the laws of
the State of New York  applicable  to contracts  made and to be performed in the
State of New York.

16.  Effectiveness of the Plan

     The Plan shall be effective as of the Spinoff Date.

                                                                    

                 1998 IMS HEALTH INCORPORATED REPLACEMENT PLAN
        FOR CERTAIN NON-EMPLOYEE DIRECTORS HOLDING COGNIZANT CORPORATION
                              EQUITY-BASED AWARDS


1.   Purpose of the Plan

     The  purpose  of the  1998 IMS  Health  Incorporated  Replacement  Plan for
Certain Non-employee Directors Holding Cognizant Corporation Equity-Based Awards
is to provide for the award of substantially identical replacement stock options
to  certain  non-employee  directors  of IMS  Health  Incorporated,  a  Delaware
corporation  whose  awards  under the 1996  Cognizant  Corporation  Non-Employee
Directors'  Stock  Incentive Plan were cancelled  pursuant to the spinoff of the
Company  from  Cognizant  Corporation,  a  Delaware  corporation  and to certain
retired non-employee  directors who elect,  pursuant to the Spinoff, to have the
awards granted under the Cognizant Plan cancelled (the "Eligible Holders").  The
Company expects that the Plan will aid the Company in attracting,  retaining and
compensating  non-employee  directors  and to  enable  them  to  increase  their
ownership  of  Shares.  The  Plan  will be  beneficial  to the  Company  and its
shareholders  since  it will  allow  non-employee  directors  to have a  greater
personal  financial  stake in the Company  through the  ownership of Shares,  in
addition to underscoring  their common interest with  shareholders in increasing
the value of the Shares on a long-term basis. It is the intention of the Company
that the terms of the  replacement  awards will (i)  substantially  preserve the
economic value of the cancelled  Cognizant  awards and (ii) except for the terms
described in Sections 7, 8 and 9 of this Plan, remain substantially identical to
the terms of the cancelled Cognizant awards.

3.   Shares Subject to the Plan

     The total  number of Shares  which may be issued under the Plan is equal to
the aggregate number of Shares to be issued as replacement awards, as calculated
pursuant to Sections 7 and 8 of this Plan.  The Shares may consist,  in whole or
in part,  of unissued  Shares or  treasury  shares.  After the initial  grant of
awards, no further awards shall be granted under the Plan.

4.   Administration

     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 "non-employee directors" within the meaning of Rule 16b-3
under the Act (or any successor  rule  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, Eligible Holders and their beneficiaries or successors).

5.   Eligibility

     Only Eligible  Holders shall receive  grants of  replacement  stock options
under the Plan.

6.   Limitations

     Options  hereunder  shall only be granted in replacement of Cognizant Stock
Options  (as  defined in  Section  7(a) of the Plan)  held by  Eligible  Holders
immediately prior to the Spinoff Date.


7.   Terms and Conditions of Options

     Options  granted  under the Plan shall be  non-qualified  stock options for
federal income tax purposes, as evidenced by the related Option 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:


<PAGE>

                                                                               7

     (a) Generally.  As of the Spinoff, each unexercised stock option held by an
Eligible  Holder that was granted under the Cognizant  Plan (a "Cognizant  Stock
Option")  shall  be  cancelled,   and  such  Eligible  Holder  shall  receive  a
replacement  stock option pursuant to this Plan. The number of Shares covered by
each replacement  stock option shall be determined by (i) multiplying the number
of shares of Cognizant  common stock  covered by the cancelled  Cognizant  Stock
Option by a fraction, the numerator of which is the average of the Daily Average
Trading Prices of Cognizant common stock for the five  consecutive  trading days
immediately  preceding the first date on which Cognizant  common stock is traded
ex-dividend,  and the  denominator  of which is the average of the Daily Average
Trading Prices of the Shares for the five  consecutive  trading days starting on
the first  date on which the  Shares  are  traded  regular  way (the  "Cognizant
Ratio")  and (ii)  rounding  down the result to a whole  number of  shares.  The
option price of each  replacement  stock option shall be  determined by dividing
the option price of the cancelled Cognizant Stock Option by the Cognizant Ratio.
Unless  otherwise  specified  in this Plan,  all other terms of the  replacement
stock  options  shall remain  substantially  identical to those of the cancelled
Cognizant  Stock Options as set forth in the Cognizant  Plan and related  option
agreement(s).

     (b) Exercisability.  Except as set forth in the Plan, stock options granted
under the Plan shall have  substantially  identical  terms as those of the stock
options originally granted under the Cognizant Plan; provided,  however, that in
no event shall a  replacement  stock option be  exercisable  more than ten years
after the date the original option was granted under the Cognizant Plan.

     (c) Exercise of Options.  Except as otherwise  provided in the Plan or in a
related  Option  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) in the following
sentence.  The purchase  price for the Shares as to which an Option is exercised
shall be paid to the Company in full at the time of exercise at the  election of
the Eligible Holder (i) in cash, (ii) in Shares having a Fair Market Value equal
to the aggregate 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

                                                                               8

deliver  promptly to the Company an amount equal to the  aggregate  Option Price
for the Shares  being  purchased.  No Eligible  Holder  shall have any rights to
dividends or other rights of a stockholder  with respect to Shares subject to an
Option until the  Eligible  Holder 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)  Exercisability  Upon  Termination of Service by Death.  If an Eligible
Holder's service with the Company and its  Subsidiaries  terminates by reason of
death after the date of grant of an Option, (i) the unexercised  portion of such
Option shall  immediately  vest in full 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.

     (e) Exercisability Upon Termination of Service by Disability or Retirement.
If an Eligible Holder's service with the Company and its Subsidiaries terminates
by reason of Disability or Retirement after the date of grant of an Option,  (i)
the unexercised  portion of such Option shall  immediately vest in full 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 such  termination
of service;  provided,  however, that if an Eligible Holder dies within a period
of five years after such termination of service,  the unexercised portion of the
Option may  thereafter  be  exercised,  during the shorter of (i) the  remaining
stated  term of the  Option or (ii) the  period  that is the  longer of (A) five
years  after the date of such  termination  of service or (B) one year after the
date of death.

     (f) Effect of Other Termination of Service. If an Eligible Holder's service
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  unexercised  portion  of an  Option  may  thereafter  be
exercised  during  the  period  ending  ninety  days  after  the  date  of  such
termination  of  service,  but only to the  extent  to  which  such  Option  was
exercisable at the time of such termination of service.

8.   Terms and Conditions of Restricted Stock

     As  of  the  Spinoff  Date,  Cognizant  Restricted  Stock  and  IMS  Health
Restricted  Stock  held by an  Eligible  Holder  shall  be  forfeited,  and such
Eligible  Holder shall receive  replacement  restricted  stock  pursuant to this
Plan.  The number of shares of  



<PAGE>

                                                                               9


restricted  stock shall equal (i) the number of shares of  forfeited  IMS Health
Restricted  Stock  plus  (ii)  the  number  of  shares  of  forfeited  Cognizant
Restricted Stock multiplied by a fraction, the numerator of which is the average
of the Daily  Average  Trading  Prices of  Cognizant  common  stock for the five
consecutive  trading days  starting on the  ex-dividend  trading  date,  and the
denominator  of which is the average of the Daily Average  Trading Prices of the
Shares for the five consecutive trading days starting on the first date on which
the Shares are traded regular way. Unless otherwise  specified in this Plan, all
other  terms of the  replacement  restricted  stock shall  remain  substantially
identical to those of the forfeited  Cognizant  Restricted Stock as set forth in
the  applicable   Cognizant  Plans  and  related   Cognizant   Restricted  Stock
agreement(s).

9.   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 or other  corporate  exchange,  or any  distribution  to  shareholders of
Shares other than regular cash dividends,  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 and/or (iii) any other
affected terms of such Awards.

     (b) Change in Control.  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.

10.  Successors and Assigns

     The Plan shall be binding on all  successors and assigns of the Company and
an Eligible Holder,  including without  limitation,

                                                                              10

the estate of such Eligible Holder and the executor, administrator or trustee of
such estate,  or any receiver or trustee in bankruptcy or  representative of the
Eligible Holder's creditors.

11.  Amendments or Termination

     The Board may  amend,  alter or  discontinue  the Plan,  but no  amendment,
alteration or discontinuation shall be made which would impair the rights of any
Eligible  Holder  under any Award  theretofore  granted  without  such  Eligible
Holder's consent.

12.  Nontransferability of Awards

     An Award shall not be  transferable  or assignable  by the Eligible  Holder
otherwise  than by will or by the laws of descent and  distribution.  During the
lifetime  of an Eligible  Holder,  an Award  shall be  exercisable  only by such
Eligible Holder.  An Award exercisable after the death of an Eligible Holder may
be exercised by the legatees,  personal  representatives  or distributees of the
Eligible Holder. Notwithstanding anything to the contrary herein, the Committee,
in its sole  discretion,  shall have the  authority to waive this Section 12 (or
any part  thereof) to the extent that this  Section 12 (or any part  thereof) is
not  required  under the rules  promulgated  under any law,  rule or  regulation
applicable to the Company.

13.  Choice of Law

     The Plan shall be governed by and construed in accordance  with the laws of
the State of New York  applicable  to contracts  made and to be performed in the
State of New York.

14.  Effectiveness of the Plan

     The Plan shall be effective as of the Spinoff Date.

                        RESTRICTED STOCK UNITS AGREEMENT

                        UNITS RESULTING FROM PERS AWARDS
                     UNDER THE 1998 IMS HEALTH INCORPORATED
                         EMPLOYEES' STOCK INCENTIVE PLAN

This Restricted  Stock Units Agreement (the  "Agreement")  confirms the grant of
Restricted  Stock Units  ("RSUs")  on  ____________  (the  "Grant  Date") by the
Compensation and Benefits  Committee (the "Committee") of the Board of Directors
of IMS Health Incorporated (the "Company") as follows:

       Participant Granted RSUs:

       Number of RSUs Granted:

The RSUs are granted based upon the achievement of performance conditions during
1998,  in  accordance  with the  Company's  Performance-Based  Restricted  Stock
Program (the "PERS program") under the 1998 IMS Health  Incorporated  Employees'
Stock   Incentive   Plan  (the   "Plan").   Accordingly,   the  RSUs   represent
performance-based  restricted  stock units or "PERS" as to which the performance
conditions  have  been  satisfied.  The RSUs are  subject  to all the  terms and
conditions  of the Plan,  which is attached  hereto and  incorporated  herein by
reference,  and are  subject  to the terms  and  conditions  of this  Agreement,
including the Terms and Conditions attached hereto.

Participant  acknowledges and agrees that (i), until an RSU has become vested in
accordance  with  Section  2(a)  hereof,  such RSU will be  subject to a risk of
forfeiture to the extent provided in Section 2 hereof, and (ii), until the later
of the time  each RSU  becomes  vested  or the end of any  additional  period of
deferral  elected by Participant in accordance  with Section 4 hereof,  such RSU
shall be generally nontransferable, as provided in Section 3 hereof.

IN WITNESS  WHEREOF,  IMS Health  Incorporated  has caused this  Agreement to be
executed by its officer thereunto duly authorized.

By the  Company's  signature,  and your  acceptance  of these RSUs,  you and the
Company agree to the terms of this  Agreement.  If you make any election in this
Agreement,  you must sign the  Agreement  and  return it to the Human  Resources
Department.

                               Term and Conditions

                            of Restricted Stock Units


1.   Restricted Stock Units

     Each RSU  represents  a  generally  nontransferable,  conditional  right to
receive  one share of the  Company's  Common  Stock (a  "Share")  at a specified
future date,  together  with a right to Dividend  Equivalents  and other rights,
subject to the terms and  conditions  of the Plan and this  Agreement.  RSUs are
bookkeeping units, and do not represent  ownership of Shares or any other equity
security.  The Company shall maintain a bookkeeping account for Participant (the
"Account")  reflecting the number of RSUs then credited to Participant hereunder
as a result  of this  grant  of RSUs and any  crediting  of  additional  RSUs to
Participant  pursuant to payments  equivalent to dividends  paid on Shares under
Section 5 ("Dividend  Equivalents").  For purposes of this  Agreement,  the term
"RSUs"  includes  RSUs as to which the risk of  forfeiture  has lapsed but which
remain subject to deferral of settlement.

2.   Vesting and Forfeiture.

     (a) RSUs granted  hereunder shall vest (meaning that the risk of forfeiture
of such RSUs shall lapse) at the earliest of (i) [4:00 pm on December 31, 20001]
[the second  anniversary of the Grant Date] (the "Scheduled  Lapse Date") , (ii)
Termination of Employment (as defined below) by reason of Retirement (as defined
in the Plan),  (iii)  Termination of Employment by reason of death or Disability
(as defined in the Plan), (iv) the occurrence of a Change in Control (as defined
in the  Plan),  or (v) any other  event  specified  in an  employment  agreement
between the  Company and  Participant  in effect at the time of  Termination  of
Employment.  In addition,  a portion of the RSUs, if not otherwise vested, shall
vest upon the  Participant's  Termination  of  Employment by the Company not for
Cause (as defined  below),  which  portion  shall equal the total number of RSUs
originally  granted  pursuant to this  Agreement  multiplied  by a fraction  the
numerator  of which is the number of days  elapsed  from January 1, 1999 through
the date of Termination of Employment and the denominator of which is the number
of days from January 1, 1999 through the Scheduled Lapse Date. Each RSU credited
as a result of Dividend  Equivalents on a forfeitable RSU under Section 5(a)[(i)
shall  be fully  vested  and  nonforfeitable  from  and  after  the date of such
crediting,  and each RSU  credited  as a result of  Dividend  Equivalents  under
Section 5(a)(ii) and (iii)] shall vest at the time of vesting of the forfeitable
RSU which gives rise, directly or indirectly,  to the crediting of such Dividend
Equivalent RSU. Each RSU credited as a result of Dividend  Equivalents on a then
non-forfeitable  RSU under Section 5(a) shall be fully vested and nonforfeitable
from and after the date of such crediting.

     (b) In the event of Participant's Termination of Employment, all RSUs which
are not vested at or prior to the time of such  Termination  shall be forfeited,
unless otherwise determined by the Committee. Thus, upon Participant's voluntary
Termination  of  Employment  or a  Termination  of Employment by the Company for
Cause, unvested RSUs generally will be forfeited.


- - ----------
(1)  Note to draft:  This date would allow the vesting PERS to be excluded  from
     the  footnote  to the  Summary  Compensation  Table  showing  the  value of
     restricted stock held at the end of the prior fiscal year.


<PAGE>


     (c) For purposes of this  Agreement,  a "Termination  of Employment"  shall
mean a termination of Participant's  employment with the Company or a subsidiary
or  affiliate  of the Company if,  immediately  thereafter,  Participant  is not
employed by any of the Company or its subsidiaries or affiliates.


<PAGE>


     (d) For purposes of this Agreement,  "Cause" shall have the meaning defined
in an employment  agreement between the Company and Participant in effect at the
time of Termination of Employment or, if there is no such employment  agreement,
"Cause" shall mean (a) willful  malfeasance or willful misconduct by Participant
in connection with his or her employment, (b) continuing failure to perform such
duties  as are  requested  by any  employee  to whom  the  Participant  reports,
directly or  indirectly,  or by the board of  directors of either the Company or
the subsidiary or affiliate employs  Participant,  (c) failure by Participant to
observe  material  policies of the Company or his or her employer  applicable to
Participant,  or (d) the commission by Participant of (i) any felony or (ii) any
misdemeanor involving moral turpitude.

3.   Nontransferability.

     Until RSUs  become  settleable  under  Section 4 hereof,  RSUs shall not be
transferable other than by will or by the laws of descent and distribution or to
a  designated  beneficiary  in the  event of  Participant's  death,  and no such
transfer shall be effective to bind the Company unless the Committee  shall have
been  furnished with a copy of such will or such other evidence as the Committee
may deem necessary to establish the validity of the transfer.

4.   Settlement and Election to Defer Settlement.

     RSUs granted hereunder, together with RSUs credited as a result of Dividend
Equivalents,  shall be  settled  by  delivery  of one  Share  for each RSU being
settled.  Settlement of an RSU granted  hereunder  shall occur upon the lapse of
the risk of forfeiture of such RSU under Section 2, except  settlement  shall be
deferred in certain cases if so elected by Participant  in accordance  with this
Section 4. Settlement of RSUs which directly or indirectly  result from Dividend
Equivalents on RSUs granted  hereunder  shall occur at the time of settlement of
the granted RSU.

     By filling out this Section 4, signing, and returning this Agreement to the
Human Resources Department at least six months prior to Scheduled Lapse Date (or
such other  deadline as may be specified  by the  Director of Human  Resources),
Participant  may  elect to defer the date of  settlement  of RSUs.  An  election
hereunder  shall  be  effective  only in the  case of  RSUs  which,  but for the
election,  would have been  settled more than six months after the filing of the
election.

     Check Only One:

     ____ I hereby  elect to have my RSUs  settled upon the lapse of the risk of
          forfeiture  under Section 2 (Note:  This election will apply if you do
          not return  the  Agreement  to the  Company or if you do not check any
          box).

     ____ I hereby  elect to defer  the  settlement  of my RSUs  until the first
          business day of the year  (subject to  accelerated  settlement  in the
          event of a Change  of  Control  Event,  death of the  Participant,  or
          Termination of Employment for any reason other than Retirement).

     ____ I hereby elect to defer the settlement of my RSUs until my Termination
          of Employment for any reason.  Termination  of Employment  includes my
          death or Disability.

     [Any  elective  deferral  will be  subject  to such  additional  terms  and
conditions as

<PAGE>

the Committee may impose,  including  terms and  conditions  under the Company's
1999 Deferred Compensation Plan.]

5.   Dividend Equivalents and Adjustments.

     (a) Dividend Equivalents shall be paid or credited on RSUs (other than RSUs
that, at the relevant record date, previously have been settled or forfeited) as
follows:

       (i)    Cash  Dividends.  If the Company  declares  and pays a dividend or
              distribution on Common Stock in the form of cash, then a number of
              additional RSUs shall be credited to  Participant's  Account as of
              the payment date for such  dividend or  distribution  equal to the
              number of RSUs  credited  to the Account as of the record date for
              such  dividend or  distribution  multiplied  by the amount of cash
              actually paid as a dividend or  distribution  on each  outstanding
              Share at such payment date,  divided by the Fair Market Value of a
              Share at such payment date.

       (ii)   Non-Share  Dividends.  If the Company declares and pays a dividend
              or distribution on Common Stock in the form of property other than
              Shares,  then a number of  additional  RSUs shall be  credited  to
              Participant's  Account as of the payment date for such dividend or
              distribution  equal to the number of RSUs  credited to the Account
              as of the record date for such dividend or distribution multiplied
              by the Fair  Market  Value  of such  property  actually  paid as a
              dividend or distribution on each outstanding Share at such payment
              date,  divided by the Fair Market Value of a Share at such payment
              date.

       (iii)  Common Stock  Dividends  and Splits.  If the Company  declares and
              pays a dividend  or  distribution  on Common  Stock in the form of
              additional  Shares,  or there  occurs a  forward  split of  Common
              Stock,  then a number of  additional  RSUs  shall be  credited  to
              Participant's  Account as of the payment date for such dividend or
              distribution or forward split equal to the number of RSUs credited
              to  the  Account  as of the  record  date  for  such  dividend  or
              distribution  or split  multiplied  by the  number  of  additional
              Shares  actually paid as a dividend or  distribution  or issued in
              such split in respect of each outstanding Share.

     (b)  The  number  of  RSUs  credited  to  Participant's  Account  shall  be
appropriately   adjusted,  in  order  to  prevent  dilution  or  enlargement  of
Participants'  rights  with  respect  to RSUs,  to  reflect  any  changes in the
outstanding  Shares resulting from any event referred to in Section 10(a) of the
Plan,  taking into account any RSUs credited to Participant  in connection  with
such event under Section 5(a) hereof.

6.   Other Terms Relating to RSUs.

     (a) The number of RSUs  credited to a  Participant's  Account shall include
fractional RSUs calculated to at least three decimal  places,  unless  otherwise
determined by the Committee. Upon settlement of RSUs, Participant shall be paid,
in cash,  an amount equal to the value of any  fractional  share that would have
otherwise  been  deliverable  in  settlement  of such RSUs,  unless the  Company
arranges  to deliver  shares to an account of  Participant  to which  fractional
shares  may be  credited  without  requiring  the  Company  to in  fact  issue a
fractional share.

     (b) It shall be a condition to the  obligation  of the Company to issue and
deliver  Shares  in  settlement  of  the  RSUs  that  the  Participant  (or  any
Beneficiary)  pay to the 


<PAGE>

Company or a  Participating  Company,  upon its  demand,  such  amount as may be
requested by the Company for the purpose of satisfying any liability to withhold
federal,  state, or local income or other taxes. If the amount  requested is not
paid,  the Company may refuse to deliver  the shares in  settlement  of the RSUs
until such  amount is paid.  The  Committee  may,  in its  discretion,  permit a
Participant (or any Beneficiary of a Participant) to pay all or a portion of the
amount  requested  by the Company for such taxes at such time and in such manner
as the Committee  shall deem to be  appropriate,  including by  authorizing  the
Company  to  withhold  from the  shares to be  delivered  in  settlement,  or by
agreeing to surrender to the Company on or about the date such tax  liability is
determinable, Shares having a fair market value (as determined by the Committee)
equal to the amount of such tax  liability  or a  specified  portion of such tax
liability.

     (c) An individual statement of each Participant's Account will be issued to
each  Participant  not less frequently than  [annually].  Such statements  shall
reflect  the amount of RSUs  credited  to  Participant's  Account,  transactions
therein during the period covered by the statement, and other information deemed
relevant by the [Director of Human Resources].  Such a statement may be combined
with or include information regarding other plans and compensatory  arrangements
relating to Participant.  A Participant's  statements  shall be deemed a part of
this Agreement, and shall evidence the Company's obligations in respect of RSUs,
including  the number of RSUs credited as a result of Dividend  Equivalents  (if
any);  provided,  however,  that any  statement  containing  an error  shall not
represent a binding obligation to the extent of such error.

7.   Miscellaneous.

     (a) This  Agreement  shall be legally  binding  when  executed  by both the
Company,  provided  that no  election  of  Participant  will be  binding  unless
Participant  has executed the Agreement  and returned it to the Human  Resources
Department of the Company.

     (b)  This   Agreement   shall  be  binding   upon  the  heirs,   executors,
administrators  and successors of the parties.  This Agreement  constitutes  the
entire  agreement  between the parties with respect to the RSUs,  and supersedes
any prior  agreements  or  documents  with  respect to the RSUs.  No  amendment,
alteration,  suspension,  discontinuation or termination of this Agreement which
may impose any  additional  obligation  upon the Company or impair the rights of
Participant with respect to the RSUs shall be valid unless in each instance such
amendment, alteration,  suspension,  discontinuation or termination is expressed
in a written  instrument  duly executed in the name and on behalf of the Company
and by Participant.

     (c) All designations of Beneficiary shall be on such forms as are specified
by and filed with the Human Resources  Department.  Any Beneficiary  designation
made by Participant  in accordance  with this provision may be changed from time
to time,  without  the consent of any  previously  designated  Beneficiary  (but
subject to any  spousal  consent as may be  required),  by filing with the Human
Resources  Department  a  notice  of such  change  on the form  provided  by the
Committee and such change of Beneficiary designation shall become effective upon
receipt by the Committee. In the event Participant's Beneficiary would otherwise
become entitled to a distribution hereunder, and all Beneficiaries designated by
Participant are not then living,  or if no valid  Beneficiary  designation is in
effect, Participant's estate or duly authorized personal representative shall be
deemed to have been designated by Participant.

     (d) Any provision for distribution in settlement of  Participant's  Account
hereunder  shall be by means of bookkeeping  entries on the books of the Company
and shall not create in  Participant or any  Beneficiary  any right to, or claim
against any,  specific assets of the Company,  nor result in the creation of any
trust or escrow account for Participant or any  


<PAGE>

Beneficiary.  Participant  or  any  Beneficiary  entitled  to  any  distribution
hereunder shall be a general creditor of the Company.

     (e)  Capitalized  terms used in this Agreement but not defined herein shall
have the same  meanings  as in the Plan.  If there is any  conflict  between the
provisions of this  Agreement and the  provisions of the Plan, the provisions of
the Plan shall govern.

     By  signing  below and  returning  this  Agreement  to the Human  Resources
Department,  I elect to defer  settlement of the RSUs until the applicable  date
specified in Section 4, subject to earlier settlement in accordance with Section
4 and the other terms of the Plan and this Agreement.  (Note: If you do not wish
to defer settlement past the Scheduled Lapse Date, you do not need to sign below
and return this  Agreement to the Human  Resources  Department.  If you elect to
further defer  settlement,  you should retain a copy of this  Agreement for your
records.)

                         RESTRICTED STOCK UNITS GRANTED
                     UNDER THE 1998 IMS HEALTH INCORPORATED
                         EMPLOYEES' STOCK INCENTIVE PLAN

This Restricted  Stock Units Agreement (the  "Agreement")  confirms the grant of
Restricted  Stock Units  ("RSUs")  on  ____________  (the  "Grant  Date") by the
Compensation and Benefits  Committee (the "Committee") of the Board of Directors
of IMS Health Incorporated (the "Company") as follows:

                  Participant Granted RSUs:

                  Number of RSUs Granted:

The RSUs are granted  under the 1998 IMS Health  Incorporated  Employees'  Stock
Incentive  Plan  (the  "Plan").  The  RSUs  are  subject  to all the  terms  and
conditions  of the Plan,  which is attached  hereto and  incorporated  herein by
reference,  and are  subject  to the terms  and  conditions  of this  Agreement,
including the Terms and Conditions attached hereto.

Participant  acknowledges and agrees that (i), until an RSU has become vested in
accordance  with  Section  2(a)  hereof,  such RSU will be  subject to a risk of
forfeiture to the extent provided in Section 2 hereof, and (ii), until the later
of the time  each RSU  becomes  vested  or the end of any  additional  period of
deferral  elected by Participant in accordance  with Section 4 hereof,  such RSU
shall be generally nontransferable, as provided in Section 3 hereof.

IN WITNESS  WHEREOF,  IMS Health  Incorporated  has caused this  Agreement to be
executed by its officer thereunto duly authorized.

By the  Company's  signature,  and your  acceptance  of these RSUs,  you and the
Company agree to the terms of this  Agreement.  If you make any election in this
Agreement,  you must sign the  Agreement  and  return it to the Human  Resources

                               Term and Conditions

                            of Restricted Stock Units

1.   Restricted Stock Units

     Each RSU  represents  a  generally  nontransferable,  conditional  right to
receive  one share of the  Company's  Common  Stock (a  "Share")  at a specified
future date,  together  with a right to Dividend  Equivalents  and other rights,
subject to the terms and  conditions  of the Plan and this  Agreement.  RSUs are
bookkeeping units, and do not represent  ownership of Shares or any other equity
security.  The Company shall maintain a bookkeeping account for Participant (the
"Account")  reflecting the number of RSUs then credited to Participant hereunder
as a result  of this  grant  of RSUs and any  crediting  of  additional  RSUs to
Participant  pursuant to payments  equivalent to dividends  paid on Shares under
Section 5 ("Dividend  Equivalents").  For purposes of this  Agreement,  the term
"RSUs"  includes  RSUs as to which the risk of  forfeiture  has lapsed but which
remain subject to deferral of settlement.

2.   Vesting and Forfeiture.

     (a) RSUs granted  hereunder shall vest (meaning that the risk of forfeiture
of such RSUs  shall  lapse)  [as to  one-third  of the RSUs on each of the first
three anniversaries of the Grant Date (each being a "Scheduled Lapse Date")] [on
the first  anniversary of the Grant Date (the "Scheduled  Lapse Date")],  except
that all RSUs  shall  vest on an  accelerated  basis  upon the  earliest  of (i)
Termination of Employment (as defined below) by reason of Retirement (as defined
in the Plan),  (ii)  Termination  of Employment by reason of death or Disability
(as  defined  in the Plan),  (iii) the  occurrence  of a Change in  Control  (as
defined  in the  Plan),  or (iv) any  other  event  specified  as  resulting  in
acceleration  of  RSUs  in an  employment  agreement  between  the  Company  and
Participant in effect at the time of Termination of Employment.  [In addition, a
portion of the RSUs, if not otherwise vested,  shall vest upon the Participant's
Termination of Employment by the Company not for Cause (as defined below), which
portion  shall  equal the  number of  unvested  RSUs  remaining  subject to this
Agreement and having the same Scheduled  Lapse Date multiplied by a fraction the
numerator of which is the number of days elapsed from the Grant Date through the
date of Termination of Employment and the  denominator of which is the number of
days from the Grant Date through such  Scheduled  Lapse Date.] Each RSU credited
as a result of Dividend  Equivalents on a forfeitable RSU under Section 5(a)[(i)
shall  be fully  vested  and  nonforfeitable  from  and  after  the date of such
crediting,  and each RSU  credited  as a result of  Dividend  Equivalents  under
Section 5(a)(ii) and (iii)] shall vest at the time of vesting of the forfeitable
RSU which gives rise, directly or indirectly,  to the crediting of such Dividend
Equivalent RSU. Each RSU credited as a result of Dividend  Equivalents on a then
non-forfeitable  RSU under Section 5(a) shall be fully vested and nonforfeitable
from and after the date of such crediting.

     (b) In the event of Participant's Termination of Employment, all RSUs which
are not vested at or prior to the time of such  Termination  shall be forfeited,
unless otherwise determined by the Committee. Thus, upon Participant's voluntary
Termination  of  Employment  or a  Termination  of Employment by the Company for
Cause, unvested RSUs generally will be forfeited.

     (c) For purposes of this  Agreement,  a "Termination  of Employment"  shall
mean a termination of Participant's  employment with the Company or a subsidiary
or  affiliate  of the Company if,  immediately  thereafter,  Participant  is not
employed by any of the Company or 

<PAGE>

its subsidiaries or affiliates.

     (d) For purposes of this Agreement,  "Cause" shall have the meaning defined
in an employment  agreement between the Company and Participant in effect at the
time of Termination of Employment or, if there is no such employment  agreement,
"Cause" shall mean (a) willful  malfeasance or willful misconduct by Participant
in connection with his or her employment, (b) continuing failure to perform such
duties  as are  requested  by any  employee  to whom  the  Participant  reports,
directly or  indirectly,  or by the board of  directors of either the Company or
the subsidiary or affiliate employs  Participant,  (c) failure by Participant to
observe  material  policies of the Company or his or her employer  applicable to
Participant,  or (d) the commission by Participant of (i) any felony or (ii) any
misdemeanor involving moral turpitude.

3.   Nontransferability.

     Until RSUs  become  settleable  under  Section 4 hereof,  RSUs shall not be
transferable other than by will or by the laws of descent and distribution or to
a  designated  beneficiary  in the  event of  Participant's  death,  and no such
transfer shall be effective to bind the Company unless the Committee  shall have
been  furnished with a copy of such will or such other evidence as the Committee
may deem necessary to establish the validity of the transfer.

4.   Settlement and Election to Defer Settlement.

     RSUs granted hereunder, together with RSUs credited as a result of Dividend
Equivalents,  shall be  settled  by  delivery  of one  Share  for each RSU being
settled.  Settlement of an RSU granted  hereunder  shall occur upon the lapse of
the risk of forfeiture of such RSU under Section 2, except  settlement  shall be
deferred in certain cases if so elected by Participant  in accordance  with this
Section 4. Settlement of RSUs which directly or indirectly  result from Dividend
Equivalents on RSUs granted  hereunder  shall occur at the time of settlement of
the granted RSU.

     By filling out this Section 4, signing, and returning this Agreement to the
Human Resources Department at least six months prior to Scheduled Lapse Date for
any affected RSUs (or such other deadline as may be specified by the Director of
Human Resources), Participant may elect to defer the date of settlement of RSUs.
An election hereunder shall be effective only in the case of RSUs which, but for
the  election,  would have been settled more than six months after the filing of
the election.

     Check Only One:

     ____ I hereby  elect to have my RSUs  settled upon the lapse of the risk of
          forfeiture  under Section 2 (Note:  This election will apply if you do
          not return  the  Agreement  to the  Company or if you do not check any
          box).

     ____ I hereby  elect to defer  the  settlement  of my RSUs  until the first
          business day of the year  (subject to  accelerated  settlement  in the
          event of a Change  of  Control  Event,  death of the  Participant,  or
          Termination of Employment for any reason other than Retirement).

     ____ I hereby elect to defer the settlement of my RSUs until my Termination
          of Employment for any reason.  Termination  of Employment  includes my
          death or Disability.
<PAGE>

     [Any  elective  deferral  will be  subject  to such  additional  terms  and
conditions as the Committee may impose, including terms and conditions under the
Company's 1999 Deferred Compensation Plan.]

5.   Dividend Equivalents and Adjustments.

     (a) Dividend Equivalents shall be paid or credited on RSUs (other than RSUs
that, at the relevant record date, previously have been settled or forfeited) as
follows:

       (i)    Cash  Dividends.  If the Company  declares  and pays a dividend or
              distribution on Common Stock in the form of cash, then a number of
              additional RSUs shall be credited to  Participant's  Account as of
              the payment date for such  dividend or  distribution  equal to the
              number of RSUs  credited  to the Account as of the record date for
              such  dividend or  distribution  multiplied  by the amount of cash
              actually paid as a dividend or  distribution  on each  outstanding
              Share at such payment date,  divided by the Fair Market Value of a
              Share at such payment date.

       (ii)   Non-Share  Dividends.  If the Company declares and pays a dividend
              or distribution on Common Stock in the form of property other than
              Shares,  then a number of  additional  RSUs shall be  credited  to
              Participant's  Account as of the payment date for such dividend or
              distribution  equal to the number of RSUs  credited to the Account
              as of the record date for such dividend or distribution multiplied
              by the Fair  Market  Value  of such  property  actually  paid as a
              dividend or distribution on each outstanding Share at such payment
              date,  divided by the Fair Market Value of a Share at such payment
              date.

       (iii)  Common Stock  Dividends  and Splits.  If the Company  declares and
              pays a dividend  or  distribution  on Common  Stock in the form of
              additional  Shares,  or there  occurs a  forward  split of  Common
              Stock,  then a number of  additional  RSUs  shall be  credited  to
              Participant's  Account as of the payment date for such dividend or
              distribution or forward split equal to the number of RSUs credited
              to  the  Account  as of the  record  date  for  such  dividend  or
              distribution  or split  multiplied  by the  number  of  additional
              Shares  actually paid as a dividend or  distribution  or issued in
              such split in respect of each outstanding Share.

     (b)  The  number  of  RSUs  credited  to  Participant's  Account  shall  be
appropriately   adjusted,  in  order  to  prevent  dilution  or  enlargement  of
Participants'  rights  with  respect  to RSUs,  to  reflect  any  changes in the
outstanding  Shares resulting from any event referred to in Section 10(a) of the
Plan,  taking into account any RSUs credited to Participant  in connection  with
such event under Section 5(a) hereof.

6.   Other Terms Relating to RSUs.

     (a) The number of RSUs  credited to a  Participant's  Account shall include
fractional RSUs calculated to at least three decimal  places,  unless  otherwise
determined by the Committee. Upon settlement of RSUs, Participant shall be paid,
in cash,  an amount equal to the value of any  fractional  share that would have
otherwise  been  deliverable  in  settlement  of such RSUs,  unless the  Company
arranges  to deliver  shares to an account of  Participant  to which  fractional
shares  may be  credited  without  requiring  the  Company  to in  fact  issue a
fractional share.

<PAGE>

     (b) It shall be a condition to the  obligation  of the Company to issue and
deliver  Shares  in  settlement  of  the  RSUs  that  the  Participant  (or  any
Beneficiary)  pay to the Company or a  Participating  Company,  upon its demand,
such amount as may be requested by the Company for the purpose of satisfying any
liability to withhold  federal,  state,  or local income or other taxes.  If the
amount  requested  is not paid,  the Company may refuse to deliver the shares in
settlement  of the RSUs until such  amount is paid.  The  Committee  may, in its
discretion,  permit a Participant  (or any  Beneficiary of a Participant) to pay
all or a portion of the amount  requested  by the Company for such taxes at such
time and in such manner as the Committee shall deem to be appropriate, including
by  authorizing  the  Company to  withhold  from the shares to be  delivered  in
settlement, or by agreeing to surrender to the Company on or about the date such
tax liability is determinable,  Shares having a fair market value (as determined
by the  Committee)  equal to the  amount of such tax  liability  or a  specified
portion of such tax liability.

     (c) An individual statement of each Participant's Account will be issued to
each  Participant  not less frequently than  [annually].  Such statements  shall
reflect  the amount of RSUs  credited  to  Participant's  Account,  transactions
therein during the period covered by the statement, and other information deemed
relevant by the [Director of Human Resources].  Such a statement may be combined
with or include information regarding other plans and compensatory  arrangements
relating to Participant.  A Participant's  statements  shall be deemed a part of
this Agreement, and shall evidence the Company's obligations in respect of RSUs,
including  the number of RSUs credited as a result of Dividend  Equivalents  (if
any);  provided,  however,  that any  statement  containing  an error  shall not
represent a binding obligation to the extent of such error.

7.   Miscellaneous.

     (a) This  Agreement  shall be legally  binding  when  executed  by both the
Company,  provided  that no  election  of  Participant  will be  binding  unless
Participant  has executed the Agreement  and returned it to the Human  Resources
Department of the Company.

     (b)  This   Agreement   shall  be  binding   upon  the  heirs,   executors,
administrators  and successors of the parties.  This Agreement  constitutes  the
entire  agreement  between the parties with respect to the RSUs,  and supersedes
any prior  agreements  or  documents  with  respect to the RSUs.  No  amendment,
alteration,  suspension,  discontinuation or termination of this Agreement which
may impose any  additional  obligation  upon the Company or impair the rights of
Participant with respect to the RSUs shall be valid unless in each instance such
amendment, alteration,  suspension,  discontinuation or termination is expressed
in a written  instrument  duly executed in the name and on behalf of the Company
and by Participant.

     (c) All designations of Beneficiary shall be on such forms as are specified
by and filed with the Human Resources  Department.  Any Beneficiary  designation
made by Participant  in accordance  with this provision may be changed from time
to time,  without  the consent of any  previously  designated  Beneficiary  (but
subject to any  spousal  consent as may be  required),  by filing with the Human
Resources  Department  a  notice  of such  change  on the form  provided  by the
Committee and such change of Beneficiary designation shall become effective upon
receipt by the Committee. In the event Participant's Beneficiary would otherwise
become entitled to a distribution hereunder, and all Beneficiaries designated by
Participant are not then living,  or if no valid  Beneficiary  designation is in
effect, Participant's estate or duly authorized personal representative shall be
deemed to have been designated by Participant.

<PAGE>

     (d) Any provision for distribution in settlement of  Participant's  Account
hereunder  shall be by means of bookkeeping  entries on the books of the Company
and shall not create in  Participant or any  Beneficiary  any right to, or claim
against any,  specific assets of the Company,  nor result in the creation of any
trust or escrow account for Participant or any  Beneficiary.  Participant or any
Beneficiary  entitled to any distribution  hereunder shall be a general creditor
of the Company.

     (e)  Capitalized  terms used in this Agreement but not defined herein shall
have the same  meanings  as in the Plan.  If there is any  conflict  between the
provisions of this  Agreement and the  provisions of the Plan, the provisions of
the Plan shall govern.

                          PURCHASED OPTIONS OPPORTUNITY
                (Summary of Employee Stock Option Incentive Plan)



       Certain  participants  in the Plan,  in addition to a stock option grant,
have been provided the opportunity to purchase stock options.

       Unlike an outright option grant, a participant  must commit to pay 10% of
the Option  Price of a Purchased  Option at the time of grant.  The Option Price
will be the Fair Market  Value (as defined on the  Election  Form) of the Common
Stock on the grant date.

       By signing a Purchased Option election form the participant agrees to pay
10% of the  Option  Price  on the date  designated.  The  remaining  90% will be
payable if and when the options are exercised.

       Purchasing options is voluntary.  A participant may purchase a minimum of
1,000 Purchased Options up to a maximum number offered to the participant.  This
is a one-time  opportunity which, if not acted upon by the designated date, will
expire.

       The 10% purchase price is  non-refundable if the Purchased Options expire
without  being  exercised.  However,  there will be a refund of a portion of the
purchase price if the participant's  employment is terminated  voluntarily or by
the Company  without  "cause",  as defined in the Plan. In that event,  only the
portion of the purchase price  attributable to those Purchased Options that have
not yet vested will be refunded.  The portion of the purchase price attributable
to those Purchased Options that have vested will be forfeited.

       The Purchased  Options vest in equal _____  increments  over _____ years.
Thus, as an example,  if employment is terminated  without cause after one year,
the participant will forfeit _____ of the original 10% purchase price.

       Upon retirement,  death or disability, the general rules set forth in the
Plan apply to determine when options vest and for what extended  period (if any)
they may be exercised.  If any Purchased  Options remain  unvested at the end of
such extended exercise period,  the participant will receive only the portion of
the purchase price  attributable  to those  Purchased  Options that have not yet
vested,  and will forfeit the portion  attributable to those  Purchased  options
that have vested.

       The 10%  purchase  price is a down payment on the full Option  Price.  As
such, it will bear no interest, nor can a participant borrow against it.

       Payment of the 10% purchase  price does not entitle a participant  to any
of the rights of a Company  stockholder.  Only by exercising a Purchased  Option
and  paying the rest of the Option  Price will a  participant  obtain any Common
Stock.


                                                                   Exhibit 10.15

                             FOR CERTAIN EXECUTIVES
                           OF IMS HEALTH INCORPORATED

[JobTitle]
[Company]

Dear [LastName]:

     IMS Health Incorporated (the "Company")  considers it essential to the best
interests  of  its  stockholders  to  foster  the  continued  employment  of key
management personnel. In this connection,  the Board of Directors of the Company
(the  "Board")  recognizes  that the  possibility  of a change in  ownership  or
control  of the  Company  may result in the  departure  or  distraction  of such
personnel  to the  detriment of the Company and its  stockholders.  As you are a
skilled and dedicated executive with important  management  responsibilities and
talents,  the Company believes that its best interests will be served if you are
encouraged to remain with the Company.

     The   Company   has   determined   that  your   ability  to  perform   your
responsibilities  and utilize your  talents for the benefit of the Company,  and
the  Company's  ability  to retain  you as an  employee,  will be  significantly
enhanced if you are provided with fair and reasonable  protection from the risks
of a change in  ownership or control of the  Company.  Accordingly,  in order to
induce you to remain in the employ of the Company,  you and the Company agree as
follows:

     1. Term of Agreement.

     (a)  Generally.  Except  as  provided  in  Section  1(b)  hereof,  (i) this
Agreement  shall be effective as of the date on which the shares of common stock
of the  Company  that  are  owned by  Cognizant  Corporation  ("Cognizant")  are
distributed to the holders of record of shares of Cognizant (July 1, 1998),  and
shall  continue in effect  through  December 31, 2001,  and (ii)  commencing  on
January  1,  2002,  and each  January  1  thereafter,  this  Agreement  shall be
automatically  extended for one additional year unless, not later than September
30th of the preceding  year,  either party to this Agreement gives notice to the
other  that the  Agreement  shall  not be  extended  under  this  Section  1(a);
provided,  however,  that no such notice by the Company  shall be effective if a
Change in Control or Potential  Change in Control (both as defined herein) shall
have occurred prior to the date of such notice.

     (b) Upon a Change in Control. If a Change in Control shall have occurred at
any time during the period in which this Agreement is effective,  this Agreement
shall  continue in effect for (i) the remainder of the month in which the Change
in Control occurred and (ii) a term of 24


<PAGE>


months  beyond the month in which such Change in Control  occurred  (such entire
period hereinafter referred to as the "Protected Period").

     2. Change in Control; Potential Change in Control.

     (a) A "Change in Control"  shall be deemed to have  occurred if, during the
term of this Agreement:

          (i) any  "Person," as such term is used for purposes of Section  13(d)
     or 14(d) of the Securities  Exchange Act of 1934, as amended (the "Exchange
     Act")  (other  than the  Company,  any trustee or other  fiduciary  holding
     securities  under an employee  benefit plan of the Company,  or any company
     owned,  directly  or  indirectly,  by the  stockholders  of the  Company in
     substantially  the  same  proportions  as their  ownership  of stock of the
     Company),  becomes the  "Beneficial  Owner" (as defined in Rule 13d-3 under
     the Exchange  Act),  directly or  indirectly,  of securities of the Company
     representing  20% or more of the  combined  voting  power of the  Company's
     then-outstanding securities;

          (ii) during any period of twenty-four months (not including any period
     prior  to the  effectiveness  of this  Agreement),  individuals  who at the
     beginning of such period  constitute the Board, and any new director (other
     than (A) a director nominated by a Person who has entered into an agreement
     with the Company to effect a transaction  described in Sections  (2)(a)(i),
     (iii) or (iv) hereof, (B) a director nominated by any Person (including the
     Company) who publicly  announces an intention to take or to consider taking
     actions  (including,  but not  limited  to, an actual or  threatened  proxy
     contest) which if consummated would constitute a Change in Control or (C) a
     director  nominated by any Person who is the Beneficial Owner,  directly or
     indirectly,  of securities of the Company  representing  10% or more of the
     combined  voting power of the Company's  securities)  whose election by the
     Board or nomination for election by the Company's stockholders was approved
     in advance by a vote of at least  two-thirds  (2/3) of the  directors  then
     still in office who either were directors at the beginning of the period or
     whose election or nomination for election was previously so approved, cease
     for any reason to constitute at least a majority thereof;

          (iii) the  stockholders  of the  Company  approve any  transaction  or
     series of  transactions  under which the Company is merged or  consolidated
     with any other  company,  other  than a merger or  consolidation  (A) which
     would  result  in  the  voting   securities  of  the  Company   outstanding
     immediately  prior  thereto  continuing  to represent  (either by remaining
     outstanding or by being  converted into voting  securities of the surviving
     entity)  more  than 66 2/3% of the  combined  voting  power  of the  voting
     securities of the Company or such surviving entity outstanding  immediately
     after such merger 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 adopts a resolution to the effect that,  for purposes of
     this Agreement, a Change in Control has occurred.

     (b) A "Potential Change in Control" shall be deemed to have occurred if:

          (i) the Company enters into an agreement,  the  consummation  of which
     would result in the occurrence of a Change in Control;



                                       2
<PAGE>


          (ii)  any  Person  (including  the  Company)  publicly   announces  an
     intention to take or to consider taking actions which if consummated  would
     constitute a Change in Control; or

          (iii) the Board adopts a resolution  to the effect that,  for purposes
     of this Agreement, a Potential Change in Control has occurred.

     (c) Employee Covenants. You agree that, subject to the terms and conditions
of this  Agreement,  in the event of a  Potential  Change in  Control,  you will
remain in the employ of the  Company  until the  earliest of (i) a date which is
180 days from the  occurrence  of such  Potential  Change in  Control,  (ii) the
termination of your  employment by reason of Disability  (as defined  herein) or
(iii)  the date on which you first  become  entitled  under  this  Agreement  to
receive the benefits provided in Section 3(b) hereof.

     (d) Company Covenant Regarding Potential Change in Control. In the event of
a  Potential  Change in  Control,  the  Company  shall,  not later  than 15 days
thereafter,  have established one or more rabbi trusts and shall deposit therein
cash in an amount  sufficient  to  provide  for full  payment  of all  potential
obligations of the Company that would arise assuming consummation of a Change in
Control and a subsequent termination of your employment under Section 3(b). Such
rabbi trust(s) shall be irrevocable  and shall provide that the Company may not,
directly or  indirectly,  use or recover any assets of the  trust(s)  until such
time as all  obligations  which  potentially  could  arise  hereunder  have been
settled and paid in full, subject only to the claims of creditors of the Company
in the event of insolvency or bankruptcy of the Company.

     3. Termination.

     (a) Termination by the Company for Cause, by You Without Good Reason, or by
Reason of Death or Disability. If during the Protected Period your employment by
the Company is terminated by the Company for Cause,  by you without Good Reason,
or because of your death or  Disability,  the  Company  shall be relieved of its
obligation  to make any  payments  to you other than (i) its  payment of amounts
otherwise  accrued and owing but not yet paid and (ii) any amounts payable under
then-existing employee benefit programs at the time such amounts are due.

     (b) Termination by the Company Without Cause or by You for Good Reason.  If
during the Protected  Period your employment by the Company is terminated by the
Company  without  cause or by you for Good Reason,  you shall be entitled to the
compensation and benefits  described in this Section 3(b). If your employment by
the  Company is  terminated  prior to a Change in  Control  at the  request of a
Person engaging in a transaction or series of transactions  that would result in
a Change in Control,  the Protected  Period shall  commence upon the  subsequent
occurrence  of a Change in Control,  your actual  termination  shall be deemed a
termination  occurring  during the Protected  Period and covered by this Section
3(b),  your Date of  Termination  shall be deemed to have  occurred  immediately
following the Change in Control,  and Notice of  Termination  shall be deemed to
have been given by the Company  immediately  prior to your  actual  termination.
Your continued employment shall not constitute consent to, or a waiver of rights
with  respect to, any  circumstances  constituting  Good Reason  hereunder.  The
compensation and benefits provided under this Section 3(b) are as follows:

          (i) The Company  shall pay you your full base salary  through the Date
     of  Termination  at the rate in effect at the time Notice of Termination is
     given, no later than the fifth day following the Date of  Termination,  and
     you shall  receive all other  amounts to which you are  entitled  under any
     compensation or benefit plan of the Company,  at the time such payments are
     due.

          (ii) At the time  specified in Section 3(d) hereof,  the Company shall
     pay you, in lieu of any further  salary,  bonus or  severance  payments for
     periods  subsequent to the Date of  Termination,  a lump sum amount in cash
     equal to three times the sum of:



                                       3
<PAGE>


               (A)  the  greater  of (I)  your  annual  base  salary  in  effect
          immediately prior to the Change in Control of the Company or (II) your
          annual  base  salary in effect at the time  Notice of  Termination  is
          given; and

               (B) the greater of (I) your annual  target  bonus for the year in
          which the Change in Control  occurs or, (II) if no such  target  bonus
          has yet been  determined  for such  year,  your  annual  target  bonus
          actually earned by you in the year  immediately  preceding the year in
          which the Change in Control occurs.

          (iii) You shall be deemed fully vested under any nonqualified  pension
     plan of a type  described  in  Section  201(2) of the  Employee  Retirement
     Income  Security Act of 1974, as amended,  in which you  participate at the
     time of the Change in Control (except for any such plan established for the
     sole purpose of restoring  qualified pension benefits that were reduced due
     to  limitations  imposed by  Sections  415 and  401(a)(7)  of the  Internal
     Revenue  Code of 1986,  as amended  (the  "Code")),  and such  nonqualified
     pension plan shall be referred to as a "Covered  Top-Hat Plan" for purposes
     of this Section 3(b)(iii). The benefit to which you shall be entitled under
     any Covered  Top-Hat Plan (the  "Covered  Top-Hat Plan  Benefit")  shall be
     determined using:

               (A) the maximum credited service allowed to be taken into account
          under the Covered Top-Hat Plan's benefit formula; and

               (B) your  salary  and bonus  taken  into  account  under  Section
          3(b)(ii) hereof as your final average compensation.

     Your Covered  Top-Hat  Plan benefit  shall be payable upon the later of (A)
     the date on  which  you  turn 55 or (B) the  date on  which  you  terminate
     employment  from the  Company.  For  purposes of  calculating  your Covered
     Top-Hat Plan Benefit,  you shall be deemed to have retired from the Company
     at  normal  retirement  age  as  if  the  Company  had  consented  to  such
     retirement.  Exhibit A to this  Agreement  sets forth an example of how the
     compensation  and benefits  provided under this Section  3(b)(iii) shall be
     determined.

          (iv) At the time  specified in Section 3(d) hereof,  the Company shall
     pay to you, in lieu of amounts  which may otherwise be payable to you under
     any bonus plan (a "Bonus Plan"), an amount in cash equal to (A) your annual
     target bonus for the year in which the Change in Control occurs, multiplied
     by a  fraction,  (I) the  numerator  of which  equals the number of full or
     partial  days in such  annual  performance  period  during  which  you were
     employed by the Company and (II) the  denominator  of which is 365, and (B)
     the entire target bonus opportunity with respect to each performance period
     in  progress  under  all  other  Bonus  Plans  in  effect  at the  time  of
     termination. Notwithstanding the foregoing, this Section 3(b)(iv) shall not
     apply with  respect to any amounts  which may  otherwise  be payable to you
     under the Company's Senior Executive Incentive Plan or any other Bonus Plan
     of the Company that applies  primarily  to "covered  employees"  within the
     meaning of Section 162(m) of the Code.

          (v) The Company shall provide you with a cash  allowance,  at the time
     specified  in  Section  3(d)  hereof,   for  outplacement  and  job  search
     activities (including, but not limited to, office and secretarial expenses)
     in the amount of 20% of your  annual base  salary and annual  target  bonus
     taken into account under Section  3(b)(ii)  hereof,  provided that (A) such
     cash allowance  shall not exceed $100,000 and (B) such cash allowance shall
     apply only to those costs or  obligations  that are  incurred by you during
     the 36-month period following your termination of employment.

          (vi) For a 36-month period  following your  termination of employment,
     the Company  shall  arrange to provide  you with life and health  insurance
     benefits no less favorable than those which you were receiving  immediately
     prior to the Notice of  Termination.  Notwithstanding  the  foregoing,  any
     benefit described in the preceding sentence shall constitute



                                       4
<PAGE>


     secondary  coverage with respect to any life and health insurance  benefits
     actually  received by you in connection with any subsequent  employment (or
     self-employment) during the 36-month period following your termination.

          (vii) Starting at age 55, you shall receive  retiree  medical and life
     benefits from the Company.  Such benefits  shall be no less  favorable than
     the  benefits  that you would have  received had you, at the time Notice of
     Termination  is given,  both (A)  attained  age 55 and (B) retired from the
     Company.  Notwithstanding  the  foregoing,  any  benefit  described  in the
     preceding  sentence  shall  constitute  secondary  coverage with respect to
     retiree  medical and life benefits  actually  received by you in connection
     with  any  subsequent   employment  (or  self-employment)   following  your
     termination.

     (c) Excise Tax. In the event you become  entitled to any amounts payable in
connection  with a Change in Control  (whether  or not such  amounts are payable
pursuant to this Agreement) (the "Severance Payments"), if any of such Severance
Payments  are subject to the tax (the "Excise  Tax")  imposed by Section 4999 of
the Code (or any  similar  federal,  state or local  tax that may  hereafter  be
imposed),  the Company  shall pay to you at the time  specified  in Section 3(d)
hereof an additional  amount (the  "Gross-Up  Payment") such that the net amount
retained by you,  after  deduction  of any Excise Tax on the Total  Payments (as
hereinafter defined) and any federal,  state and local income tax and Excise Tax
upon the payment  provided for by this Section 3(c), shall be equal to the Total
Payments. For purposes of determining whether any of the Severance Payments will
be subject to the Excise Tax and the amount of such  Excise  Tax:  (i) any other
payments or benefits  received  or to be  received by you in  connection  with a
Change in Control or your  termination  of employment  (whether  pursuant to the
terms of this  Agreement or any other plan,  arrangement  or agreement  with the
Company,  any Person whose  actions  result in a Change in Control or any Person
affiliated with the Company or such Person) (which,  together with the Severance
Payments,  constitute  the "Total  Payments")  shall be  treated  as  "parachute
payments" within the meaning of Section  280G(b)(2) of the Code, and all "excess
parachute  payments" within the meaning of Section  280G(b)(1) of the Code shall
be  treated  as  subject  to  the  Excise   Tax,   unless  in  the   opinion  of
nationally-recognized  tax  counsel  selected  by you  such  other  payments  or
benefits (in whole or in part) do not  constitute  parachute  payments,  or such
excess   parachute   payments  (in  whole  or  in  part)  represent   reasonable
compensation  for  services  actually  rendered  within  the  meaning of Section
280G(b)(4)  of the Code in excess  of the base  amount  within  the  meaning  of
Section  280G(b)(3) of the Code, or are otherwise not subject to the Excise Tax;
(ii) the amount of the Total  Payments  which shall be treated as subject to the
Excise  Tax shall be equal to the  lesser  of (A) the total  amount of the Total
Payments and (B) the amount of excess  parachute  payments within the meaning of
Section  280G(b)(1) of the Code (after  applying  Section 3(c)(i)  hereof);  and
(iii) the value of any  non-cash  benefits or any  deferred  payments or benefit
shall be determined by a  nationally-recognized  accounting firm selected by you
in accordance  with the  principles of Sections  280G(d)(3) and (4) of the Code.
For purposes of  determining  the amount of the Gross-Up  Payment,  you shall be
deemed to pay  federal  income  taxes at the  highest  marginal  rate of federal
income taxation in the calendar year in which the Gross-Up Payment is to be made
and state and local income taxes at the highest marginal rate of taxation in the
state and  locality of your  residence  on the Date of  Termination,  net of the
maximum reduction in federal income taxes which could be obtained from deduction
of such state and local taxes.  In the event that the Excise Tax is subsequently
determined  to be less than the amount taken into account  hereunder at the time
of  termination  of your  employment,  you shall repay to the Company within ten
days after the time that the amount of such  reduction  in Excise Tax is finally
determined the portion of the Gross-Up  Payment  attributable  to such reduction
(plus the portion of the  Gross-Up  Payment  attributable  to the Excise Tax and
federal and state and local  income tax imposed on the  Gross-Up  Payment  being
repaid by you if such  repayment  results  in a  reduction  in Excise Tax and/or
federal and state and local income tax deduction) plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the
event that the Excise Tax is  determined to exceed the amount taken into account
hereunder at the time of the termination of your employment (including by reason
of any payment the existence or amount of which cannot be determined at the time
of the Gross-Up Payment), the Company shall make an



                                       5
<PAGE>


additional  gross-up payment in respect of such excess within ten days after the
time that the amount of such excess is finally determined.

     (d) Time of  Payment.  The  payments  provided  for in  Sections  3(b)(ii),
3(b)(iv)  and 3(c)  hereof  shall  be made not  later  than  the  fifteenth  day
following the Date of Termination; provided, however, that if the amount of such
payments  cannot be finally  determined on or before such day, the Company shall
pay to you on such day an estimate,  as determined in good faith by the Company,
of the  minimum  amount of such  payments  and shall pay the  remainder  of such
payments  (together with interest at the rate provided in Section  1274(b)(2)(B)
of the Code) as soon as the amount  thereof  can be  determined  but in no event
later than the  thirtieth day after the Date of  Termination.  In the event that
the amount of the estimated payments exceeds the amount subsequently  determined
to have been due,  such excess  shall  constitute  a loan by the Company to you,
payable on the  fifteenth  day after the demand by the  Company  (together  with
interest  at the rate  provided  in  Section  1274(b)(2)(B)  of the  Code).  The
payments  provided in Section  3(b)(v)  hereof  shall be made not later than the
fifteenth day following the submission of each receipt to the Company evidencing
costs or obligations incurred by you in connection with outplacement  counseling
and job search activities.

     (e) Notice.  During the Protected Period, any purported termination of your
employment by the Company or by you shall be  communicated  by written Notice of
Termination to the other party hereto.

     (f) Certain  Definitions.  Except as otherwise indicated in this Agreement,
all  definitions  in this Section 3(f) shall be applicable  during the Protected
Period only.

          (i)  Disability.   "Disability"  shall  mean  your  absence  from  the
     full-time  performance of your duties with the Company for six  consecutive
     months as a result of your  incapacity due to physical or mental illness or
     disability,  and  within 30 days after  written  Notice of  Termination  is
     thereafter  given you shall not have returned to the full-time  performance
     of your duties.

          (ii)  Cause.  "Cause"  shall  mean  termination  on account of (A) the
     willful and continued  failure by you to substantially  perform your duties
     with  the  Company  (other  than  any  such  failure  resulting  from  your
     incapacity  due to physical or mental  illness or disability or any failure
     after the issuance of a Notice of Termination by you for Good Reason) which
     failure is demonstrably and materially  damaging to the financial condition
     or reputation  of the Company  and/or its  subsidiaries,  and which failure
     continues  more  than 48  hours  after a  written  demand  for  substantial
     performance  is  delivered to you by the Board,  which demand  specifically
     identifies  the  manner  in  which  the  Board  believes  that you have not
     substantially  performed your duties or (B) the willful  engaging by you in
     conduct  which is  demonstrably  and  materially  injurious to the Company,
     monetarily or  otherwise.  No act, or failure to act, on your part shall be
     deemed  "willful"  unless done,  or omitted to be done,  by you not in good
     faith and without reasonable belief that your action or omission was in the
     best interest of the Company.  Notwithstanding the foregoing, you shall not
     be deemed to have been  terminated  for Cause  unless and until there shall
     have been  delivered  to you a copy of the  resolution  duly adopted by the
     affirmative  vote of not less  than  three-quarters  (3/4)  off the  entire
     membership of the Board at a meeting of the Board (after  reasonable notice
     to you and an opportunity for you, together with your counsel,  to be heard
     before the Board) finding that, in the good faith opinion of the Board, you
     were  guilty  of  conduct  set forth  above in this  Section  3(f)(ii)  and
     specifying the particulars thereof in detail.

          (iii) Good  Reason.  "Good  Reason"  shall mean,  without your express
     written consent, the occurrence upon or after a Change in Control of any of
     the following  circumstances unless, in the case of Sections  3(f)(iii)(A),
     (E), (F) or (G) hereof, such circumstances are fully corrected prior to the
     Date of Termination specified in the Notice of Termination given in respect
     thereof:

               (A) the  assignment  to you of any duties  inconsistent  with the
          position in the Company that you held immediately  prior to the Change
          in Control,  or an adverse  alteration in the nature or status of your
          responsibilities  or the conditions of your  employment  from those in
          effect immediately prior to such Change in Control;  for this purpose,
          if, at the time of the Change in Control, you held the office of Chief
          Executive   Officer  of  the  Company,   it  shall  constitute  duties
          inconsistent  with such position if you shall be required to report to
          and take  direction  from anyone  other than the Board of Directors of
          the  Company,  and if, at the time of the Change in Control,  you held
          the  office  of  Chief  Operating  Officer  of the  Company,  it shall
          constitute  duties  inconsistent  with such  position  if you shall be
          required to report to and take  direction  from anyone  other than the
          Board of Directors or the Chief Executive Officer of the Company;

               (B) a reduction  by the Company in your annual base  salary,  any
          target  bonus or  perquisites  as in effect  immediately  prior to the
          Change in  Control or as the same may be  increased  from time to time
          except for across-the-board  perquisite reductions similarly affecting
          all senior  executives of the Company and all senior executives of any
          Person in control of the Company;

               (C) the relocation of the principle place of your employment to a

          Pennsylvania  or (V) Passaic County,  New Jersey;  except for required
          travel on the Company's business to an extent substantially consistent
          with your business travel obligations prior to the Change in Control;

               (D) the  failure by the Company to pay to you any portion of your
          compensation  or to  pay to  you  any  portion  of an  installment  of
          deferred  compensation under any deferred  compensation program of the
          Company within seven days of the date such compensation is due;

               (E) the failure by the Company to continue in effect any material
          compensation  or benefit  plan in which you  participated  immediately
          prior to the  Change  in  Control,  unless  an  equitable  arrangement
          (embodied in an ongoing  substitute or alternative plan) has been made
          with  respect to such plan,  or the failure by the Company to continue
          your participation therein (or in such substitute or alternative plan)
          on a basis not materially less favorable, both in terms of the amounts
          of benefits provided and the level of your  participation  relative to
          other participants, as existed at the time of the Change in Control;

               (F) the failure of the Company to obtain a satisfactory agreement
          from any successor to assume and agree to perform this  Agreement,  as
          contemplated in Section 6 hereof; or

               (G) any  purported  termination  of your  employment  that is not
          effected   pursuant  to  a  Notice  of   Termination   satisfying  the
          requirements  of Section  3(f)(iv)  hereof (and,  if  applicable,  the
          requirements of Section 3(f)(ii) hereof),  which purported termination
          shall not be effective for purposes of this Agreement.

          (iv) Notice of Termination.  "Notice of Termination" shall mean notice
     indicating the specific termination provision in this Agreement relied upon
     and setting forth in reasonable detail the facts and circumstances  claimed
     to provide a basis for termination of your  employment  under the provision
     so indicated.

          (v) Date of Termination.  "Date of Termination" shall mean (A) if your
     employment  is  terminated  for   Disability,   30  days  after  Notice  of
     Termination  is given  (provided  that you shall not have  returned  to the
     full-time  performance  of your duties during such 30-day period) or (B) if
     your  employment is terminated for any other reason,  the date specified in
     the Notice of



                                       7
<PAGE>


     Termination  (which,  in the case of a termination for Cause,  shall not be
     less than 30 days from the date such Notice of Termination is given and, in
     the case of a  termination  for Good Reason,  shall not be less than 15 nor
     more than 60 days from the date such Notice of Termination is given).

     4. Mitigation. Except as provided in Section 3(b)(vi) and (vii) hereof, you
shall not be required to mitigate the amount of payment  provided for under this
Agreement by seeking  other  employment  or  otherwise,  nor shall the amount of
payment  or  benefit  provided  for  under  this  Agreement  be  reduced  by any
compensation  earned by you as the result of employment by another employer,  by
retirement  benefits,  by offset against any amount claimed to be owed by you to
the Company, or otherwise.

     5. Costs of  Proceedings.  The  Company  shall pay all costs and  expenses,
including all attorneys'  fees and  disbursements,  of the Company and, at least
monthly, you in connection with any legal proceedings, whether or not instituted
by the Company or you,  relating to the  interpretation  or  enforcement  of any
provision of this Agreement;  provided that if you instituted the proceeding and
a finding  (no longer  subject to appeal)  is entered  that you  instituted  the
proceeding in bad faith, you shall pay all of your costs and expenses, including
attorneys' fees and disbursements. The Company shall pay prejudgment interest on
any money judgment obtained by you as a result of such proceeding, calculated at
the prime rate of The Chase  Manhattan  Bank as in effect from time to time from
the date that payment should have been made to you under this Agreement.

     6. Successors; Binding Agreement.

     (a) The Company shall require any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business  and/or assets of the Company to expressly  assume and agree to perform
this  Agreement in the same manner and to the same extent that the Company would
be required to perform it if no such succession had taken place. As used in this
Agreement,  "Company"  shall mean the  Company as  hereinbefore  defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

     (b) This Agreement  shall inure to the benefit of and be enforceable by you
and  your  personal  or  legal   representatives,   executors,   administrators,
successors,  heirs,  distributees,  devisees and legatees.  In the event of your
death, all amounts  otherwise  payable to you hereunder shall,  unless otherwise
provided herein,  be paid in accordance with the terms of this Agreement to your
devisee,  legatee or other  designee or, if there is no such  designee,  to your
estate.

     7.  Notice.  Notices  and all  other  communications  provided  for in this
Agreement  shall be in writing  and shall be deemed to have been duly given when
(a) personally  delivered or (b) mailed by United States certified or registered
mail,  return receipt  requested,  postage prepaid,  addressed to the respective

party may have furnished to the other in writing in accordance herewith,  except
that notice of change of address shall be effective only upon receipt.

     8. Miscellaneous. No provision of this Agreement may be modified, waived or
discharged unless such waiver, modification or discharge is agreed to in writing
and signed by you and such officer as may be designated by the Board.  No waiver
by either  party  hereto at any time of any breach by the other party hereto of,
or compliance with, any condition or provision of this Agreement to be performed
by such other party shall be deemed a waiver of similar or dissimilar provisions
or  conditions  at the time or at any prior or  subsequent  time.  The validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the  State of New York  without  regard to its  conflicts  of law
principles. All references to sections of the

Exchange  Act or the  Code  shall  be  deemed  also to  refer  to any  successor
provisions to such sections.  Any payments  provided for hereunder shall be paid
net of any applicable  withholding  required under federal,  state or local law.
The obligations of the Company under this Agreement shall survive the expiration
of this Agreement to the extent necessary to give effect to this Agreement.

     9. Validity.  The invalidity or  unenforceability  of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

     10. Counterparts.  This Agreement may be executed in counterparts,  each of
which  shall  be  deemed  to be an  original  but  all of  which  together  will
constitute one and the same instrument.

     11. Entire Agreement. This Agreement sets forth the entire agreement of the
parties hereto in respect of the subject matter  contained herein and during the

warranties,  whether oral or written, by any officer, employee or representative
of any party  hereof with respect to the subject  matter  contained  herein.  No
agreements  or  representations,  oral or  otherwise,  express or implied,  with
respect to the subject  matter  hereof have been made by either  party which are
not  expressly  set forth in this  Agreement.  Notwithstanding  anything  to the
contrary in this  Agreement,  the procedural  provisions of this Agreement shall
apply to all  benefits  payable  as a result  of a Change in  Control  (or other
change in control) under any employee benefit plan, agreement,  program,  policy
or arrangement of the Company.

     If this  letter sets forth our  agreement  on the  subject  matter  hereof,

[Company]

Dear [LastName]:

       IMS Health  Incorporated  (the  "Company")  considers it essential to the
best  interests of its  stockholders  to foster the continued  employment of key
management personnel. In this connection,  the Board of Directors of the Company
(the  "Board")  recognizes  that the  possibility  of a change in  ownership  or
control  of the  Company  may result in the  departure  or  distraction  of such
personnel  to the  detriment of the Company and its  stockholders.  As you are a
skilled and dedicated executive with important  management  responsibilities and
talents,  the Company believes that its best interests will be served if you are
encouraged to remain with the Company.

       The  Company  has   determined   that  your   ability  to  perform   your
responsibilities  and utilize your  talents for the benefit of the Company,  and
the  Company's  ability  to retain  you as an  employee,  will be  significantly
enhanced if you are provided with fair and reasonable  protection from the risks
of a change in  ownership or control of the  Company.  Accordingly,  in order to
induce you to remain in the employ of the Company,  you and the Company agree as
follows:

       1. Term of Agreement.

       (a)  Generally.  Except as  provided  in Section  1(b)  hereof,  (i) this
Agreement  shall be effective as of the date on which the shares of common stock
of the  Company  that  are  owned by  Cognizant  Corporation  ("Cognizant")  are
distributed to the holders of record of shares of Cognizant (July 1, 1998),  and
shall  continue in effect  through  December 31, 2001,  and (ii)  commencing  on
January  1,  2002,  and each  January  1  thereafter,  this  Agreement  shall be
automatically  extended for one additional year unless, not later than September
30th of the preceding  year,  either party to this Agreement gives notice to the
other  that the  Agreement  shall  not be  extended  under  this  Section  1(a);
provided,  however,  that no such notice by the Company  shall be effective if a
Change in Control or Potential  Change in Control (both as defined herein) shall
have occurred prior to the date of such notice.

       (b) Upon a Change in Control.  If a Change in Control shall have occurred
at any time  during  the  period in which  this  Agreement  is  effective,  this
Agreement  shall  continue in effect for (i) the remainder of the month in which
the Change in Control  occurred and (ii) a term of 24 months beyond the month in
which such Change in Control occurred (such entire period  hereinafter  referred
to as the "Protected Period").

       (a) A "Change in Control" shall be deemed to have occurred if, during the
term of this Agreement:

              (i) any  "Person,"  as such term is used for  purposes  of Section
       13(d) or 14(d) of the  Securities  Exchange Act of 1934,  as amended (the

       holding securities under an employee benefit plan of the Company,  or any
       company owned, directly or indirectly, by the stockholders of the Company
       in substantially  the same proportions as their ownership of stock of the
       Company),  becomes the "Beneficial Owner" (as defined in Rule 13d-3 under
       the Exchange Act),  directly or indirectly,  of securities of the Company
       representing  20% or more of the combined  voting power of the  Company's
       then-outstanding securities;

              (ii) during any period of  twenty-four  months (not  including any
       period prior to the effectiveness of this Agreement),  individuals who at
       the beginning of such period  constitute the Board,  and any new director
       (other than (A) a director  nominated by a Person who has entered into an
       agreement with the Company to effect a transaction  described in Sections
       (2)(a)(i),  (iii) or (iv) hereof,  (B) a director nominated by any Person
       (including the Company) who publicly announces an intention to take or to
       consider  taking  actions  (including,  but not  limited to, an actual or
       threatened proxy contest) which if consummated  would constitute a Change
       in  Control  or  (C) a  director  nominated  by  any  Person  who  is the
       Beneficial  Owner,  directly or indirectly,  of securities of the Company
       representing  10% or more of the combined  voting power of the  Company's
       securities) whose election by the Board or nomination for election by the
       Company's  stockholders  was  approved  in  advance by a vote of at least
       two-thirds  (2/3) of the  directors  then still in office who either were
       directors at the beginning of the period or whose  election or nomination
       for  election  was  previously  so  approved,  cease  for any  reason  to
       constitute at least a majority thereof;

              (iii) the  stockholders  of the Company approve any transaction or
       series of transactions  under which the Company is merged or consolidated
       with any other company,  other than a merger or  consolidation  (A) which
       would  result  in  the  voting  securities  of  the  Company  outstanding
       immediately  prior thereto  continuing to represent  (either by remaining
       outstanding or by being converted into voting securities of the surviving
       entity)  more than 66 2/3% of the  combined  voting  power of the  voting
       securities  of  the  Company  or  such   surviving   entity   outstanding
       immediately  after such  merger 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 adopts a resolution to the effect that, for purposes
       of this Agreement, a Change in Control has occurred.

       (b) A "Potential Change in Control" shall be deemed to have occurred if:

              (i) the Company  enters into an  agreement,  the  consummation  of
       which would result in the occurrence of a Change in Control;

              (ii) any Person  (including  the  Company)  publicly  announces an
       intention  to take or to consider  taking  actions  which if  consummated
       would constitute a Change in Control; or

              (iii)  the Board  adopts a  resolution  to the  effect  that,  for
       purposes of this Agreement, a Potential Change in Control has occurred.



                                       13

       (c)  Employee  Covenants.  You  agree  that,  subject  to the  terms  and
conditions of this Agreement, in the event of a Potential Change in Control, you
will remain in the employ of the Company  until the earliest of (i) a date which
is 180 days from the  occurrence of such Potential  Change in Control,  (ii) the
termination of your  employment by reason of Disability  (as defined  herein) or
(iii)  the date on which you first  become  entitled  under  this  Agreement  to
receive the benefits provided in Section 3(b) hereof.

       (d) Company Covenant Regarding  Potential Change in Control. In the event
of a Potential  Change in Control,  the  Company  shall,  not later than 15 days
thereafter,  have established one or more rabbi trusts and shall deposit therein
cash in an amount  sufficient  to  provide  for full  payment  of all  potential
obligations of the Company that would arise assuming consummation of a Change in
Control and a subsequent termination of your employment under Section 3(b). Such
rabbi trust(s) shall be irrevocable  and shall provide that the Company may not,
directly or  indirectly,  use or recover any assets of the  trust(s)  until such
time as all  obligations  which  potentially  could  arise  hereunder  have been
settled and paid in full, subject only to the claims of creditors of the Company
in the event of insolvency or bankruptcy of the Company.

       3. Termination.

       (a) Termination by the Company for Cause, by You Without Good Reason,  or
by Reason of Death or Disability. If during the Protected Period your employment
by the  Company is  terminated  by the Company  for Cause,  by you without  Good
Reason, or because of your death or Disability, the Company shall be relieved of
its obligation to make any payments to you other than (i) its payment of amounts
otherwise  accrued and owing but not yet paid and (ii) any amounts payable under
then-existing employee benefit programs at the time such amounts are due.

       (b)  Termination by the Company  Without Cause or by You for Good Reason.
If during the Protected  Period your  employment by the Company is terminated by
the Company  without  cause or by you for Good Reason,  you shall be entitled to
the compensation and benefits described in this Section 3(b). If your employment
by the  Company is  terminated  prior to a Change in Control at the request of a
Person engaging in a transaction or series of transactions  that would result in
a Change in Control,  the Protected  Period shall  commence upon the  subsequent
occurrence  of a Change in Control,  your actual  termination  shall be deemed a
termination  occurring  during the Protected  Period and covered by this Section
3(b),  your Date of  Termination  shall be deemed to have  occurred  immediately
following the Change in Control,  and Notice of  Termination  shall be deemed to
have been given by the Company  immediately  prior to your  actual  termination.
Your continued employment shall not constitute consent to, or a waiver of rights
with  respect to, any  circumstances  constituting  Good Reason  hereunder.  The
compensation and benefits provided under this Section 3(b) are as follows:

              (i) The Company  shall pay you your full base  salary  through the
       Date  of  Termination  at the  rate  in  effect  at the  time  Notice  of
       Termination  is given,  no later than the fifth day following the Date of
       Termination,  and you shall  receive  all other  amounts to which you are
       entitled under any  compensation  or benefit plan of the Company,  at the
       time such payments are due.

              (ii) At the time  specified in Section  3(d)  hereof,  the Company
       shall pay you, in lieu of any further salary, bonus or severance payments
       for periods  subsequent to the Date of Termination,  a lump sum amount in
       cash equal to three times the sum of:

                     (A) the  greater of (I) your  annual  base salary in effect
              immediately  prior to the Change in Control of the Company or (II)
              your   annual  base  salary  in  effect  at  the  time  Notice  of
              Termination is given; and



                                       14
<PAGE>


                     (B) the  greater of (I) your  annual  target  bonus for the
              year in which the  Change in Control  occurs  or,  (II) if no such
              target bonus has yet been  determined  for such year,  your annual
              target  bonus  actually  earned  by you in  the  year  immediately
              preceding the year in which the Change in Control occurs.

              (iii) At the time  specified in Section  3(d) hereof,  the Company
       shall pay to you, in lieu of amounts  which may  otherwise  be payable to
       you under any bonus plan (a "Bonus Plan"), an amount in cash equal to (A)
       your  annual  target  bonus for the year in which the  Change in  Control
       occurs,  multiplied by a fraction,  (I) the numerator of which equals the
       number of full or partial days in such annual  performance  period during
       which you were employed by the Company and (II) the  denominator of which
       is 365, and (B) the entire target bonus  opportunity with respect to each
       performance  period in progress  under all other Bonus Plans in effect at
       the time of  termination.  Notwithstanding  the  foregoing,  this Section
       3(b)(iii) shall not apply with respect to any amounts which may otherwise
       be payable to you under the Company's Senior Executive  Incentive Plan or
       any other Bonus Plan of the Company  that  applies  primarily to "covered
       employees" within the meaning of Section 162(m) of the Code.

              (iv) The Company shall provide you with a cash  allowance,  at the
       time specified in Section 3(d) hereof,  for  outplacement  and job search
       activities  (including,  but  not  limited  to,  office  and  secretarial
       expenses)  in the  amount of 20% of your  annual  base  salary and annual
       target bonus taken into account under Section 3(b)(ii)  hereof,  provided
       that (A) such cash allowance  shall not exceed $100,000 and (B) such cash
       allowance  shall  apply  only to  those  costs  or  obligations  that are
       incurred by you during the 36-month period  following your termination of
       employment.

              (v)  For  a  36-month   period   following  your   termination  of
       employment, the Company shall arrange to provide you with life and health
       insurance  benefits no less favorable than those which you were receiving
       immediately  prior to the  Notice  of  Termination.  Notwithstanding  the
       foregoing,   any  benefit  described  in  the  preceding  sentence  shall
       constitute  secondary  coverage  with  respect  to any  life  and  health
       insurance  benefits  actually  received  by you in  connection  with  any
       subsequent  employment (or  self-employment)  during the 36-month  period
       following your termination.

              (vi)  Starting at age 55, you shall  receive  retiree  medical and
       life benefits from the Company.  Such benefits shall be no less favorable
       than the  benefits  that you would  have  received  had you,  at the time
       Notice of Termination is given,  both (A) attained age 55 and (B) retired
       from the Company. Notwithstanding the foregoing, any benefit described in
       the preceding  sentence shall constitute  secondary coverage with respect
       to  retiree  medical  and  life  benefits  actually  received  by  you in
       connection with any subsequent employment (or self-employment)  following
       your termination.

       (c) Excise Tax. In the event you become  entitled to any amounts  payable
in connection with a Change in Control  (whether or not such amounts are payable
pursuant to this Agreement) (the "Severance Payments"), if any of such Severance
Payments  are subject to the tax (the "Excise  Tax")  imposed by Section 4999 of
the Code (or any  similar  federal,  state or local  tax that may  hereafter  be
imposed),  the Company  shall pay to you at the time  specified  in Section 3(d)
hereof an additional  amount (the  "Gross-Up  Payment") such that the net amount
retained by you,  after  deduction  of any Excise Tax on the Total  Payments (as
hereinafter defined) and any federal,  state and local income tax and Excise Tax
upon the payment  provided for by this Section 3(c), shall be equal to the Total
Payments. For purposes of determining whether any of the Severance Payments will
be subject to the Excise Tax and the amount of such  Excise  Tax:  (i) any other
payments or benefits  received  or to be  received by you in  connection  with a
Change in Control or your  termination  of employment  (whether  pursuant to the
terms of this  Agreement or any other plan,  arrangement  or agreement  with the
Company,  any Person whose  actions  result in a Change in Control or any Person
affiliated with the Company or such Person) (which,  together with the Severance
Payments, constitute the "Total Payments") shall be treated as "parachute



                                       15
<PAGE>


payments" within the meaning of Section  280G(b)(2) of the Code, and all "excess
parachute  payments" within the meaning of Section  280G(b)(1) of the Code shall
be  treated  as  subject  to  the  Excise   Tax,   unless  in  the   opinion  of
nationally-recognized  tax  counsel  selected  by you  such  other  payments  or
benefits (in whole or in part) do not  constitute  parachute  payments,  or such
excess   parachute   payments  (in  whole  or  in  part)  represent   reasonable
compensation  for  services  actually  rendered  within  the  meaning of Section
280G(b)(4)  of the Code in excess  of the base  amount  within  the  meaning  of
Section  280G(b)(3) of the Code, or are otherwise not subject to the Excise Tax;
(ii) the amount of the Total  Payments  which shall be treated as subject to the
Excise  Tax shall be equal to the  lesser  of (A) the total  amount of the Total
Payments and (B) the amount of excess  parachute  payments within the meaning of
Section  280G(b)(1) of the Code (after  applying  Section 3(c)(i)  hereof);  and
(iii) the value of any  non-cash  benefits or any  deferred  payments or benefit
shall be determined by a  nationally-recognized  accounting firm selected by you
in accordance  with the  principles of Sections  280G(d)(3) and (4) of the Code.
For purposes of  determining  the amount of the Gross-Up  Payment,  you shall be
deemed to pay  federal  income  taxes at the  highest  marginal  rate of federal
income taxation in the calendar year in which the Gross-Up Payment is to be made
and state and local income taxes at the highest marginal rate of taxation in the
state and  locality of your  residence  on the Date of  Termination,  net of the
maximum reduction in federal income taxes which could be obtained from deduction
of such state and local taxes.  In the event that the Excise Tax is subsequently
determined  to be less than the amount taken into account  hereunder at the time
of  termination  of your  employment,  you shall repay to the Company within ten
days after the time that the amount of such  reduction  in Excise Tax is finally
determined the portion of the Gross-Up  Payment  attributable  to such reduction
(plus the portion of the  Gross-Up  Payment  attributable  to the Excise Tax and
federal and state and local  income tax imposed on the  Gross-Up  Payment  being
repaid by you if such  repayment  results  in a  reduction  in Excise Tax and/or
federal and state and local income tax deduction) plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the
event that the Excise Tax is  determined to exceed the amount taken into account
hereunder at the time of the termination of your employment (including by reason
of any payment the existence or amount of which cannot be determined at the time
of the Gross-Up Payment),  the Company shall make an additional gross-up payment
in respect of such excess within ten days after the time that the amount of such
excess is finally determined.

       (d) Time of Payment.  The  payments  provided  for in Sections  3(b)(ii),
3(b)(iii)  and 3(c)  hereof  shall  be made not  later  than the  fifteenth  day
following the Date of Termination; provided, however, that if the amount of such
payments  cannot be finally  determined on or before such day, the Company shall
pay to you on such day an estimate,  as determined in good faith by the Company,
of the  minimum  amount of such  payments  and shall pay the  remainder  of such
payments  (together with interest at the rate provided in Section  1274(b)(2)(B)
of the Code) as soon as the amount  thereof  can be  determined  but in no event
later than the  thirtieth day after the Date of  Termination.  In the event that
the amount of the estimated payments exceeds the amount subsequently  determined
to have been due,  such excess  shall  constitute  a loan by the Company to you,
payable on the  fifteenth  day after the demand by the  Company  (together  with
interest  at the rate  provided  in  Section  1274(b)(2)(B)  of the  Code).  The
payments  provided in Section  3(b)(iv)  hereof shall be made not later than the
fifteenth day following the submission of each receipt to the Company evidencing
costs or obligations incurred by you in connection with outplacement  counseling
and job search activities.

       (e) Notice.  During the Protected  Period,  any purported  termination of
your employment by the Company or by you shall be communicated by written Notice
of Termination to the other party hereto.

       (f) Certain Definitions. Except as otherwise indicated in this Agreement,
all  definitions  in this Section 3(f) shall be applicable  during the Protected
Period only.

              (i)  Disability.  "Disability"  shall mean your  absence  from the
       full-time performance of your duties with the Company for six consecutive
       months as a result of your



                                       16
<PAGE>


       incapacity due to physical or mental illness or disability, and within 30
       days after written Notice of  Termination  is thereafter  given you shall
       not have returned to the full-time performance of your duties.

              (ii) Cause.  "Cause" shall mean  termination on account of (A) the
       willful and continued failure by you to substantially perform your duties
       with the  Company  (other  than  any such  failure  resulting  from  your
       incapacity due to physical or mental illness or disability or any failure
       after the  issuance of a Notice of  Termination  by you for Good  Reason)
       which failure is  demonstrably  and materially  damaging to the financial
       condition or reputation of the Company and/or its subsidiaries, and which
       failure  continues  more  than  48  hours  after  a  written  demand  for
       substantial  performance  is delivered to you by the Board,  which demand
       specifically  identifies  the manner in which the Board believes that you
       have not substantially  performed your duties or (B) the willful engaging
       by you in conduct which is demonstrably  and materially  injurious to the
       Company, monetarily or otherwise. No act, or failure to act, on your part
       shall be deemed  "willful" unless done, or omitted to be done, by you not
       in good faith and without  reasonable belief that your action or omission
       was in the best interest of the Company.  Notwithstanding  the foregoing,
       you shall not be deemed to have  been  terminated  for Cause  unless  and
       until there  shall have been  delivered  to you a copy of the  resolution
       duly  adopted  by the  affirmative  vote of not less than  three-quarters
       (3/4) off the  entire  membership  of the Board at a meeting of the Board
       (after reasonable notice to you and an opportunity for you, together with
       your  counsel,  to be heard before the Board)  finding  that, in the good
       faith opinion of the Board, you were guilty of conduct set forth above in
       this Section 3(f)(ii) and specifying the particulars thereof in detail.

              (iii) Good Reason.  "Good Reason" shall mean, without your express
       written consent,  the occurrence upon or after a Change in Control of any
       of  the  following   circumstances   unless,  in  the  case  of  Sections
       3(f)(iii)(A),  (E),  (F) or (G)  hereof,  such  circumstances  are  fully
       corrected  prior to the Date of  Termination  specified  in the Notice of
       Termination given in respect thereof:

                     (A) the assignment to you of any duties  inconsistent  with
              the position in the Company that you held immediately prior to the
              Change in  Control,  or an  adverse  alteration  in the  nature or
              status  of  your   responsibilities  or  the  conditions  of  your
              employment from those in effect  immediately  prior to such Change
              in Control;

                     (B) a reduction  by the Company in your annual base salary,
              any target bonus or perquisites as in effect  immediately prior to
              the Change in Control or as the same may be increased from time to
              time except for across-the-board  perquisite  reductions similarly
              affecting  all senior  executives  of the  Company  and all senior
              executives of any Person in control of the Company;

                     (C)  the   relocation  of  the  principle   place  of  your
              employment  to a location  more than 50 miles from the location of
              such place of employment on the date of this Agreement; except for
              required   travel  on  the   Company's   business   to  an  extent
              substantially  consistent  with your business  travel  obligations
              prior to the Change in Control;

                     (D) the failure by the Company to pay to you any portion of
              your  compensation  or to pay to you any portion of an installment
              of deferred  compensation under any deferred  compensation program
              of the Company within seven days of the date such  compensation is
              due;

                     (E) the  failure by the  Company to  continue in effect any
              material  compensation  or benefit plan in which you  participated
              immediately  prior to the Change in Control,  unless an  equitable
              arrangement  (embodied  in an ongoing  substitute  or  alternative
              plan) has been made with  respect to such plan,  or the failure by
              the Company to  continue  your  participation  therein (or in such
              substitute or alternative plan) on a basis not materially



                                       17
<PAGE>


              less favorable,  both in terms of the amounts of benefits provided
              and  the   level   of  your   participation   relative   to  other
              participants, as existed at the time of the Change in Control;

                     (F) the  failure of the  Company  to obtain a  satisfactory
              agreement  from any  successor to assume and agree to perform this
              Agreement, as contemplated in Section 6 hereof; or

                     (G) any purported  termination of your  employment  that is
              not effected  pursuant to a Notice of  Termination  satisfying the
              requirements of Section  3(f)(iv) hereof (and, if applicable,  the
              requirements  of  Section   3(f)(ii)   hereof),   which  purported
              termination shall not be effective for purposes of this Agreement.

              (iv) Notice of  Termination.  "Notice of  Termination"  shall mean
       notice  indicating the specific  termination  provision in this Agreement
       relied  upon and  setting  forth  in  reasonable  detail  the  facts  and
       circumstances  claimed  to  provide  a  basis  for  termination  of  your
       employment under the provision so indicated.

              (v) Date of Termination.  "Date of Termination"  shall mean (A) if

       Termination  is given  (provided  that you shall not have returned to the
       full-time performance of your duties during such 30-day period) or (B) if
       your employment is terminated for any other reason, the date specified in
       the Notice of Termination (which, in the case of a termination for Cause,
       shall not be less than 30 days from the date such  Notice of  Termination
       is given and, in the case of a termination for Good Reason,  shall not be

       4. Mitigation. Except as provided in Section 3(b)(v) and (vi) hereof, you
shall not be required to mitigate the amount of payment  provided for under this
Agreement by seeking  other  employment  or  otherwise,  nor shall the amount of
payment  or  benefit  provided  for  under  this  Agreement  be  reduced  by any
compensation  earned by you as the result of employment by another employer,  by
retirement  benefits,  by offset against any amount claimed to be owed by you to
the Company, or otherwise.

       5. Costs of  Proceedings.  The Company  shall pay all costs and expenses,
including all attorneys'  fees and  disbursements,  of the Company and, at least
monthly, you in connection with any legal proceedings, whether or not instituted
by the Company or you,  relating to the  interpretation  or  enforcement  of any
provision of this Agreement;  provided that if you instituted the proceeding and
a finding  (no longer  subject to appeal)  is entered  that you  instituted  the
proceeding in bad faith, you shall pay all of your costs and expenses, including
attorneys' fees and disbursements. The Company shall pay prejudgment interest on
any money judgment obtained by you as a result of such proceeding, calculated at
the prime rate of The Chase  Manhattan  Bank as in effect from time to time from

by purchase, merger,  consolidation or otherwise) to all or substantially all of
the  business  and/or  assets of the  Company to  expressly  assume and agree to
perform  this  Agreement  in the same  manner  and to the same  extent  that the
Company would be required to perform it if no such  succession  had taken place.
As used in this  Agreement,  "Company"  shall mean the  Company as  hereinbefore

                             FOR CERTAIN EXECUTIVES
                           OF IMS HEALTH INCORPORATED


                                                         Date


PERSONAL AND CONFIDENTIAL

[FirstName]
[JobTitle]
[Company]

Dear [LastName]:

       IMS Health  Incorporated  (the  "Company")  considers it essential to the
best  interests of its  stockholders  to foster the continued  employment of key
management personnel. In this connection,  the Board of Directors of the Company
(the  "Board")  recognizes  that the  possibility  of a change in  ownership  or
control  of the  Company  may result in the  departure  or  distraction  of such
personnel  to the  detriment of the Company and its  stockholders.  As you are a
skilled and dedicated executive with important  management  responsibilities and
talents,  the Company believes that its best interests will be served if you are
encouraged to remain with the Company.

       The  Company  has   determined   that  your   ability  to  perform   your
responsibilities  and utilize your  talents for the benefit of the Company,  and
the  Company's  ability  to retain  you as an  employee,  will be  significantly
enhanced if you are provided with fair and reasonable  protection from the risks
of a change in  ownership or control of the  Company.  Accordingly,  in order to
induce you to remain in the employ of the Company,  you and the Company agree as
follows:

       1. Term of Agreement.

       (a)  Generally.  Except as  provided  in Section  1(b)  hereof,  (i) this
Agreement  shall be effective as of the date on which the shares of common stock
of the  Company  that  are  owned by  Cognizant  Corporation  ("Cognizant")  are
distributed to the holders of record of shares of Cognizant (July 1, 1998),  and
shall  continue in effect  through  December 31, 2001,  and (ii)  commencing  on
January  1,  2002,  and each  January  1  thereafter,  this  Agreement  shall be
automatically  extended for one additional year unless, not later than September
30th of the preceding  year,  either party to this Agreement gives notice to the
other  that the  Agreement  shall  not be  extended  under  this  Section  1(a);
provided,  however,  that no such notice by the Company  shall be effective if a
Change in Control or Potential  Change in Control (both as defined herein) shall
have occurred prior to the date of such notice.



                                       21
<PAGE>


       (b) Upon a Change in Control.  If a Change in Control shall have occurred
at any time  during  the  period in which  this  Agreement  is  effective,  this
Agreement  shall  continue in effect for (i) the remainder of the month in which
the Change in Control  occurred and (ii) a term of 24 months beyond the month in
which such Change in Control occurred (such entire period  hereinafter  referred
to as the "Protected Period").

       2. Change in Control; Potential Change in Control.

       (a) A "Change in Control" shall be deemed to have occurred if, during the
term of this Agreement:

              (i) any  "Person,"  as such term is used for  purposes  of Section
       13(d) or 14(d) of the  Securities  Exchange Act of 1934,  as amended (the
       "Exchange  Act") (other than the Company,  any trustee or other fiduciary
       holding securities under an employee benefit plan of the Company,  or any
       company owned, directly or indirectly, by the stockholders of the Company
       in substantially  the same proportions as their ownership of stock of the
       Company),  becomes the "Beneficial Owner" (as defined in Rule 13d-3 under
       the Exchange Act),  directly or indirectly,  of securities of the Company
       representing  20% or more of the combined  voting power of the  Company's
       then-outstanding securities;

              (ii) during any period of  twenty-four  months (not  including any
       period prior to the effectiveness of this Agreement),  individuals who at
       the beginning of such period  constitute the Board,  and any new director
       (other than (A) a director  nominated by a Person who has entered into an
       agreement with the Company to effect a transaction  described in Sections
       (2)(a)(i),  (iii) or (iv) hereof,  (B) a director nominated by any Person
       (including the Company) who publicly announces an intention to take or to
       consider  taking  actions  (including,  but not  limited to, an actual or
       threatened proxy contest) which if consummated  would constitute a Change
       in  Control  or  (C) a  director  nominated  by  any  Person  who  is the
       Beneficial  Owner,  directly or indirectly,  of securities of the Company
       representing  10% or more of the combined  voting power of the  Company's
       securities) whose election by the Board or nomination for election by the
       Company's  stockholders  was  approved  in  advance by a vote of at least
       two-thirds  (2/3) of the  directors  then still in office who either were
       directors at the beginning of the period or whose  election or nomination
       for  election  was  previously  so  approved,  cease  for any  reason  to
       constitute at least a majority thereof;

              (iii) the  stockholders  of the Company approve any transaction or
       series of transactions  under which the Company is merged or consolidated
       with any other company,  other than a merger or  consolidation  (A) which
       would  result  in  the  voting  securities  of  the  Company  outstanding
       immediately  prior thereto  continuing to represent  (either by remaining
       outstanding or by being converted into voting securities of the surviving
       entity)  more than 66 2/3% of the  combined  voting  power of the  voting
       securities  of  the  Company  or  such   surviving   entity   outstanding
       immediately  after such  merger 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 adopts a resolution to the effect that, for purposes
       of this Agreement, a Change in Control has occurred.

       (b) A "Potential Change in Control" shall be deemed to have occurred if:

              (i) the Company  enters into an  agreement,  the  consummation  of
       which would result in the occurrence of a Change in Control;



                                       22
<PAGE>


              (ii) any Person  (including  the  Company)  publicly  announces an
       intention  to take or to consider  taking  actions  which if  consummated
       would  constitute  a Change  in  Control;  or (iii)  the  Board  adopts a
       resolution  to the  effect  that,  for  purposes  of  this  Agreement,  a
       Potential Change in Control has occurred.

       (c)  Employee  Covenants.  You  agree  that,  subject  to the  terms  and
conditions of this Agreement, in the event of a Potential Change in Control, you
will remain in the employ of the Company  until the earliest of (i) a date which
is 180 days from the  occurrence of such Potential  Change in Control,  (ii) the
termination of your  employment by reason of Disability  (as defined  herein) or
(iii)  the date on which you first  become  entitled  under  this  Agreement  to
receive the benefits provided in Section 3(b) hereof.

       (d) Company Covenant Regarding  Potential Change in Control. In the event
of a Potential  Change in Control,  the  Company  shall,  not later than 15 days
thereafter,  have established one or more rabbi trusts and shall deposit therein
cash in an amount  sufficient  to  provide  for full  payment  of all  potential
obligations of the Company that would arise assuming consummation of a Change in
Control and a subsequent termination of your employment under Section 3(b). Such
rabbi trust(s) shall be irrevocable  and shall provide that the Company may not,
directly or  indirectly,  use or recover any assets of the  trust(s)  until such
time as all  obligations  which  potentially  could  arise  hereunder  have been
settled and paid in full, subject only to the claims of creditors of the Company
in the event of insolvency or bankruptcy of the Company.

       3. Termination.

       (a) Termination by the Company for Cause, by You Without Good Reason,  or
by Reason of Death or Disability. If during the Protected Period your employment
by the  Company is  terminated  by the Company  for Cause,  by you without  Good
Reason, or because of your death or Disability, the Company shall be relieved of
its obligation to make any payments to you other than (i) its payment of amounts
otherwise  accrued and owing but not yet paid and (ii) any amounts payable under
then-existing employee benefit programs at the time such amounts are due.

       (b)  Termination by the Company  Without Cause or by You for Good Reason.
If during the Protected  Period your  employment by the Company is terminated by
the Company  without  cause or by you for Good Reason,  you shall be entitled to
the compensation and benefits described in this Section 3(b). If your employment
by the  Company is  terminated  prior to a Change in Control at the request of a
Person engaging in a transaction or series of transactions  that would result in
a Change in Control,  the Protected  Period shall  commence upon the  subsequent
occurrence  of a Change in Control,  your actual  termination  shall be deemed a
termination  occurring  during the Protected  Period and covered by this Section
3(b),  your Date of  Termination  shall be deemed to have  occurred  immediately
following the Change in Control,  and Notice of  Termination  shall be deemed to
have been given by the Company  immediately  prior to your  actual  termination.
Your continued employment shall not constitute consent to, or a waiver of rights
with  respect to, any  circumstances  constituting  Good Reason  hereunder.  The
compensation and benefits provided under this Section 3(b) are as follows:

              (i) The Company  shall pay you your full base  salary  through the
       Date  of  Termination  at the  rate  in  effect  at the  time  Notice  of
       Termination  is given,  no later than the fifth day following the Date of
       Termination,  and you shall  receive  all other  amounts to which you are
       entitled under any  compensation  or benefit plan of the Company,  at the
       time such payments are due.

              (ii) At the time  specified in Section  3(d)  hereof,  the Company
       shall pay you, in lieu of any further salary, bonus or severance payments
       for periods  subsequent to the Date of Termination,  a lump sum amount in
       cash equal two times the sum of:



                                       23
<PAGE>


                     (A) the  greater of (I) your  annual  base salary in effect
              immediately  prior to the Change in Control of the Company or (II)
              your   annual  base  salary  in  effect  at  the  time  Notice  of
              Termination is given; and

                     (B) the  greater of (I) your  annual  target  bonus for the
              year in which the  Change in Control  occurs  or,  (II) if no such
              target bonus has yet been  determined  for such year,  your annual
              target  bonus  actually  earned  by you in  the  year  immediately
              preceding the year in which the Change in Control occurs.

              (iii) At the time  specified in Section  3(d) hereof,  the Company
       shall pay to you, in lieu of amounts  which may  otherwise  be payable to
       you under any bonus plan (a "Bonus Plan"), an amount in cash equal to (A)
       your  annual  target  bonus for the year in which the  Change in  Control
       occurs,  multiplied by a fraction,  (I) the numerator of which equals the
       number of full or partial days in such annual  performance  period during
       which you were employed by the Company and (II) the  denominator of which
       is 365, and (B) the entire target bonus  opportunity with respect to each
       performance  period in progress  under all other Bonus Plans in effect at
       the time of  termination.  Notwithstanding  the  foregoing,  this Section
       3(b)(iii) shall not apply with respect to any amounts which may otherwise
       be payable to you under the Company's Senior Executive  Incentive Plan or
       any other Bonus Plan of the Company  that  applies  primarily to "covered
       employees" within the meaning of Section 162(m) of the Code.

              (iv) The Company shall provide you with a cash  allowance,  at the
       time specified in Section 3(d) hereof,  for  outplacement  and job search
       activities  (including,  but  not  limited  to,  office  and  secretarial
       expenses)  in the  amount of 20% of your  annual  base  salary and annual
       target bonus taken into account under Section 3(b)(ii)  hereof,  provided
       that (A) such cash allowance  shall not exceed $100,000 and (B) such cash
       allowance  shall  apply  only to  those  costs  or  obligations  that are
       incurred by you during the 36-month period  following your termination of
       employment.

              (v)  For  a  24-month   period   following  your   termination  of
       employment, the Company shall arrange to provide you with life and health
       insurance  benefits no less favorable than those which you were receiving
       immediately  prior to the  Notice  of  Termination.  Notwithstanding  the
       foregoing,   any  benefit  described  in  the  preceding  sentence  shall
       constitute  secondary  coverage  with  respect  to any  life  and  health
       insurance  benefits  actually  received  by you in  connection  with  any
       subsequent  employment (or  self-employment)  during the 24-month  period
       following your termination.

              (vi)  Starting at age 55, you shall  receive  retiree  medical and
       life benefits from the Company.  Such benefits shall be no less favorable
       than the  benefits  that you would  have  received  had you,  at the time
       Notice of Termination is given,  both (A) attained age 55 and (B) retired
       from the Company. Notwithstanding the foregoing, any benefit described in
       the preceding  sentence shall constitute  secondary coverage with respect
       to  retiree  medical  and  life  benefits  actually  received  by  you in
       connection with any subsequent employment (or self-employment)  following
       your termination.

       (c) Excise Tax. In the event you become  entitled to any amounts  payable
in connection with a Change in Control  (whether or not such amounts are payable
pursuant to this Agreement) (the "Severance Payments"), if any of such Severance
Payments  are subject to the tax (the "Excise  Tax")  imposed by Section 4999 of
the Code (or any  similar  federal,  state or local  tax that may  hereafter  be
imposed),  the Company  shall pay to you at the time  specified  in Section 3(d)
hereof an additional  amount (the  "Gross-Up  Payment") such that the net amount
retained by you,  after  deduction  of any Excise Tax on the Total  Payments (as
hereinafter defined) and any federal,  state and local income tax and Excise Tax
upon the payment  provided for by this Section 3(c), shall be equal to the Total
Payments. For purposes of determining whether any of the Severance Payments will
be subject to the Excise Tax and the amount of such Excise Tax: (i) any



                                       24
<PAGE>


other payments or benefits  received or to be received by you in connection with
a Change in Control or your termination of employment  (whether  pursuant to the
terms of this  Agreement or any other plan,  arrangement  or agreement  with the
Company,  any Person whose  actions  result in a Change in Control or any Person
affiliated with the Company or such Person) (which,  together with the Severance
Payments,  constitute  the "Total  Payments")  shall be  treated  as  "parachute
payments" within the meaning of Section  280G(b)(2) of the Code, and all "excess
parachute  payments" within the meaning of Section  280G(b)(1) of the Code shall
be  treated  as  subject  to  the  Excise   Tax,   unless  in  the   opinion  of
nationally-recognized  tax  counsel  selected  by you  such  other  payments  or
benefits (in whole or in part) do not  constitute  parachute  payments,  or such
excess   parachute   payments  (in  whole  or  in  part)  represent   reasonable
compensation  for  services  actually  rendered  within  the  meaning of Section
280G(b)(4)  of the Code in excess  of the base  amount  within  the  meaning  of
Section  280G(b)(3) of the Code, or are otherwise not subject to the Excise Tax;
(ii) the amount of the Total  Payments  which shall be treated as subject to the
Excise  Tax shall be equal to the  lesser  of (A) the total  amount of the Total
Payments and (B) the amount of excess  parachute  payments within the meaning of
Section  280G(b)(1) of the Code (after  applying  Section 3(c)(i)  hereof);  and
(iii) the value of any  non-cash  benefits or any  deferred  payments or benefit
shall be determined by a  nationally-recognized  accounting firm selected by you
in accordance  with the  principles of Sections  280G(d)(3) and (4) of the Code.
For purposes of  determining  the amount of the Gross-Up  Payment,  you shall be
deemed to pay  federal  income  taxes at the  highest  marginal  rate of federal
income taxation in the calendar year in which the Gross-Up Payment is to be made
and state and local income taxes at the highest marginal rate of taxation in the
state and  locality of your  residence  on the Date of  Termination,  net of the
maximum reduction in federal income taxes which could be obtained from deduction
of such state and local taxes.  In the event that the Excise Tax is subsequently
determined  to be less than the amount taken into account  hereunder at the time
of  termination  of your  employment,  you shall repay to the Company within ten
days after the time that the amount of such  reduction  in Excise Tax is finally
determined the portion of the Gross-Up  Payment  attributable  to such reduction
(plus the portion of the  Gross-Up  Payment  attributable  to the Excise Tax and
federal and state and local  income tax imposed on the  Gross-Up  Payment  being
repaid by you if such  repayment  results  in a  reduction  in Excise Tax and/or
federal and state and local income tax deduction) plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the
event that the Excise Tax is  determined to exceed the amount taken into account
hereunder at the time of the termination of your employment (including by reason
of any payment the existence or amount of which cannot be determined at the time
of the Gross-Up Payment),  the Company shall make an additional gross-up payment
in respect of such excess within ten days after the time that the amount of such
excess is finally determined.

       (d) Time of Payment.  The  payments  provided  for in Sections  3(b)(ii),
3(b)(iii)  and 3(c)  hereof  shall  be made not  later  than the  fifteenth  day
following the Date of Termination; provided, however, that if the amount of such
payments  cannot be finally  determined on or before such day, the Company shall
pay to you on such day an estimate,  as determined in good faith by the Company,
of the  minimum  amount of such  payments  and shall pay the  remainder  of such
payments  (together with interest at the rate provided in Section  1274(b)(2)(B)
of the Code) as soon as the amount  thereof  can be  determined  but in no event
later than the  thirtieth day after the Date of  Termination.  In the event that
the amount of the estimated payments exceeds the amount subsequently  determined
to have been due,  such excess  shall  constitute  a loan by the Company to you,
payable on the  fifteenth  day after the demand by the  Company  (together  with
interest  at the rate  provided  in  Section  1274(b)(2)(B)  of the  Code).  The
payments  provided in Section  3(b)(iv)  hereof shall be made not later than the
fifteenth day following the submission of each receipt to the Company evidencing
costs or obligations incurred by you in connection with outplacement  counseling
and job search activities.

       (e) Notice.  During the Protected  Period,  any purported  termination of
your employment by the Company or by you shall be communicated by written Notice
of Termination to the other party hereto.

       (f) Certain Definitions. Except as otherwise indicated in this Agreement,
all  definitions  in this Section 3(f) shall be applicable  during the Protected
Period only.

              (i)  Disability.  "Disability"  shall mean your  absence  from the
       full-time performance of your duties with the Company for six consecutive
       months as a result of your  incapacity  due to physical or mental illness
       or disability,  and within 30 days after written Notice of Termination is
       thereafter given you shall not have returned to the full-time performance
       of your duties.

              (ii) Cause.  "Cause" shall mean  termination on account of (A) the
       willful and continued failure by you to substantially perform your duties
       with the  Company  (other  than  any such  failure  resulting  from  your
       incapacity due to physical or mental illness or disability or any failure
       after the  issuance of a Notice of  Termination  by you for Good  Reason)
       which failure is  demonstrably  and materially  damaging to the financial
       condition or reputation of the Company and/or its subsidiaries, and which
       failure  continues  more  than  48  hours  after  a  written  demand  for
       substantial  performance  is delivered to you by the Board,  which demand
       specifically  identifies  the manner in which the Board believes that you
       have not substantially  performed your duties or (B) the willful engaging
       by you in conduct which is demonstrably  and materially  injurious to the
       Company, monetarily or otherwise. No act, or failure to act, on your part
       shall be deemed  "willful" unless done, or omitted to be done, by you not
       in good faith and without  reasonable belief that your action or omission
       was in the best interest of the Company.  Notwithstanding  the foregoing,
       you shall not be deemed to have  been  terminated  for Cause  unless  and
       until there  shall have been  delivered  to you a copy of the  resolution
       duly  adopted  by the  affirmative  vote of not less than  three-quarters
       (3/4) off the  entire  membership  of the Board at a meeting of the Board
       (after reasonable notice to you and an opportunity for you, together with
       your  counsel,  to be heard before the Board)  finding  that, in the good
       faith opinion of the Board, you were guilty of conduct set forth above in
       this Section 3(f)(ii) and specifying the particulars thereof in detail.

              (iii) Good Reason.  "Good Reason" shall mean, without your express
       written consent,  the occurrence upon or after a Change in Control of any
       of  the  following   circumstances   unless,  in  the  case  of  Sections
       3(f)(iii)(A),  (E),  (F) or (G)  hereof,  such  circumstances  are  fully
       corrected  prior to the Date of  Termination  specified  in the Notice of
       Termination given in respect thereof:

              status  of  your   responsibilities  or  the  conditions  of  your
              employment from those in effect  immediately  prior to such Change
              in Control;

                     (B) a reduction  by the Company in your annual base salary,
              any target bonus or perquisites as in effect  immediately prior to
              the Change in Control or as the same may be increased from time to
              time except for across-the-board  perquisite  reductions similarly
              affecting  all senior  executives  of the  Company  and all senior
              executives of any Person in control of the Company;

                     (C)  the   relocation  of  the  principle   place  of  your
              employment  to a location  more than 50 miles from the location of
              such place of employment on the date of this Agreement; except for
              required   travel  on  the   Company's   business   to  an  extent
              substantially  consistent  with your business  travel  obligations
              prior to the Change in Control;

                     (D) the failure by the Company to pay to you any portion of
              your  compensation  or to pay to you any portion of an installment
              of deferred  compensation under any deferred  compensation program
              of the Company within seven days of the date such  compensation is
              due;

              material  compensation  or benefit plan in which you  participated
              immediately  prior to the Change in Control,  unless an  equitable
              arrangement  (embodied  in an ongoing  substitute  or  alternative
              plan) has been made with  respect to such plan,  or the failure by
              the Company to  continue  your  participation  therein (or in such

              favorable,  both in terms of the amounts of benefits  provided and
              the level of your participation relative to other participants, as
              existed at the time of the Change in Control;

                     (F) the  failure of the  Company  to obtain a  satisfactory
              agreement  from any  successor to assume and agree to perform this
              Agreement, as contemplated in Section 6 hereof;

                     (G) any purported  termination of your  employment  that is
              not effected  pursuant to a Notice of  Termination  satisfying the
              requirements of Section  3(f)(iv) hereof (and, if applicable,  the
              requirements  of  Section   3(f)(ii)   hereof),   which  purported
              termination shall not be effective for purposes of this Agreement;
              or

                     (H) the lapse of twelve  months  following  the last day of

       notice  indicating the specific  termination  provision in this Agreement
       relied  upon and  setting  forth  in  reasonable  detail  the  facts  and
       circumstances  claimed  to  provide  a  basis  for  termination  of  your
       employment under the provision so indicated.

              (v) Date of Termination.  "Date of Termination"  shall mean (A) if
       your  employment is terminated  for  Disability,  30 days after Notice of
       Termination  is given  (provided  that you shall not have returned to the
       full-time performance of your duties during such 30-day period) or (B) if
       your employment is terminated for any other reason, the date specified in
       the Notice of Termination (which, in the case of a termination for Cause,

       4. Mitigation. Except as provided in Section 3(b)(v) and (vi) hereof, you
shall not be required to mitigate the amount of payment  provided for under this
Agreement by seeking  other  employment  or  otherwise,  nor shall the amount of
payment  or  benefit  provided  for  under  this  Agreement  be  reduced  by any

including all attorneys'  fees and  disbursements,  of the Company and, at least

by the Company or you,  relating to the  interpretation  or  enforcement  of any
provision of this Agreement;  provided that if you instituted the proceeding and
a finding  (no longer  subject to appeal)  is entered  that you  instituted  the
proceeding in bad faith, you shall pay all of your costs and expenses, including
attorneys' fees and disbursements. The Company shall pay prejudgment interest on
any money judgment obtained by you as a result of such proceeding, calculated at
the prime rate of The Chase  Manhattan  Bank as in effect from time to time from

its business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law, or otherwise.

Agreement  shall be in writing  and shall be deemed to have been duly given when
(a) personally  delivered or (b) mailed by United States certified or registered
mail,  return receipt  requested,  postage prepaid,  addressed to the respective
addresses  set  forth on the first  page of this  Agreement;  provided  that all

or  discharged  unless such  waiver,  modification  or discharge is agreed to in
writing and signed by you and such officer as may be designated by the Board. No
waiver  by either  party  hereto  at any time of any  breach by the other  party
hereto of, or compliance  with,  any condition or provision of this Agreement to
be  performed  by such  other  party  shall be  deemed a waiver  of  similar  or
dissimilar  provisions  or  conditions at the time or at any prior or subsequent
time.  The  validity,  interpretation,  construction  and  performance  of  this
Agreement  shall be governed by the laws of the State of New York without regard

obligations of the Company under this Agreement  shall survive the expiration of
this Agreement to the extent necessary to give effect to this Agreement.

       9. Validity.  The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

       10. Counterparts. This Agreement may be executed in counterparts, each of
which  shall  be  deemed  to be an  original  but  all of  which  together  will
constitute one and the same instrument.

the parties hereto in respect of the subject matter  contained herein and during
the term of this Agreement  supersedes  the provisions of all prior  agreements,

warranties,  whether oral or written, by any officer, employee or representative
of any party  hereof with respect to the subject  matter  contained  herein.  No
agreements  or  representations,  oral or  otherwise,  express or implied,  with
respect to the subject  matter  hereof have been made by either  party which are
not  expressly  set forth in this  Agreement.  Notwithstanding  anything  to the
contrary in this  Agreement,  the procedural  provisions of this Agreement shall

change in control) under any employee benefit plan, agreement,  program,  policy
or arrangement of the Company.

Employee Benefits  Committee;  provided,  however,  that (i) an employee who has
entered  into an agreement  with the Company or a  Participating  Company  which
expressly  excludes  such  employee from  participation  in this Plan (e.g.,  by
naming this Plan or excluding participation in Company-sponsored severance plans
generally)  and  which  remains  in  effect  at  the  date  of  such  employee's
termination  of  employment  shall  not be an  Eligible  Employee;  and  (ii) an

employment  by the Company or a  Participating  Company  for any reason,  except
that, in the case of any Eligible Employee, an involuntary termination for Cause
will not  constitute  an Eligible  Termination  and, in the case of any Eligible
Employee  designated  as within  Level A,  Level B, or Level C on  Attachment  A
hereto, an involuntary  termination due to  unsatisfactory  performance will not
constitute an Eligible  Termination (unless otherwise determined by the Employee
Benefits  Committee or a person to whom such  Committee has delegated  authority
under the  Plan);  or (b) a  resignation  mutually  agreed to in  writing by the
Company or a Participating  Company and the Eligible Employee,  in which writing

not include (x) a unilateral resignation;  or (y) any termination where an offer
of employment is made to the Eligible  Employee of a comparable  position at the
Company  or an  affiliate  or, if such  termination  occurs  within  six  months

       1.9  "Participating  Company" shall mean any entity  affiliated  with the
Company which has been  designated to  participate  in the Plan by action of the
Employee Benefits Committee.

       1.10  "Salary"  shall mean an Eligible  Employee's  annual base salary in
effect  immediately  prior to his or her  termination of  employment,  except as
otherwise provided in Section 2 hereof and Section 1 of Attachment C hereto.

       1.11 "Severance  Agreement and Release" shall mean an agreement signed by
the Eligible Employee substantially in the form attached hereto as Attachment D.
The  foregoing  notwithstanding,  the Company  may, by action of its chief human
resources officer or chief legal counsel or a person delegated  authority by one
of such persons, modify the form of Severance Agreement and Release to be signed
by any Eligible  Employee,  subject to such  limitations or procedures as may be
specified by the Employee  Benefits  Committee,  and provided  that,  during the
Change in Control Period,  such Agreement shall not be modified in a manner that
increases the  obligations  or decreases the rights of the Eligible  Employee as
compared to the form of such Agreement in use prior to the Change in Control.

       1.12  "Spinoff  Date" shall mean the date on which there was effected the
distribution  of common  stock of the Company  owned by  Cognizant to holders of
record of shares of common stock, par value $0.01 per share, of Cognizant.

       1.13 "Year of Service"  shall mean,  for purposes of applying the formula
set forth in  Attachment  B, each full and partial year of  employment  with the
Company,  any  Participating  Company,  and  otherwise as specified in the final
sentence of this definition, in each case beginning with the Eligible Employee's
initial date of hire; provided,  however,  that (i) all partial years of service
shall be  aggregated  for purposes of  determining  the total number of Years of
Service;  (ii),  in the case of an Eligible  Employee  who was not  continuously
employed,  no  period of  employment  previously  taken  into  account,  if such
Eligible   Employee  was  eligible  for   severance   benefits  upon  any  prior
termination,  shall  be taken  into  account  in  determining Years 

                                       3

<PAGE>

of Service  hereunder;  and (iii), in the case of an Eligible Employee who was a
regular part-time  employee during any period of employment which would be taken
into account in  determining  his or her Years of Service,  such period shall be
adjusted to equivalent full-time employment for purposes of determining Years of
Service by  multiplying  the total  number of weeks in such period by a fraction
the  numerator of which is the total number of hours such employee was scheduled
to work during each week and the  denominator  of which is the number of hours a
full-time  employee  would have been  scheduled  to work during  such week,  and
dividing  the  product by 52. The  Eligible  Employee  shall  continue to accrue
Service  for  purposes of this  definition  during  approved  leaves of absence,
military service absences, paid holidays, paid vacations, temporary absences due
to illness or injury,  disability, or any other cause, if and to the extent that
service is customarily  accrued for purposes of the retirement  plan or plans of
the Company or Participating  Company which then employs the Eligible  Employee.
With  respect to periods of  employment  with  companies  which are  acquired or
become  affiliated  with the  Company  after the  Spinoff  Date,  any periods of
employment  of an  Eligible  Employee  prior  to  the  date  of  acquisition  or
affiliation  will not be taken  into  account  in  determining  Years of Service
unless expressly approved in writing by the Employee Benefits  Committee.  Other
provisions  of this  Plan  notwithstanding  and to the  extent  required  by any
Employee Benefits Agreement among Cognizant,  Nielsen Media Research,  Inc., and
the Company, "Years of Service" shall include all periods of employment prior to
the  Spinoff  Date to the  extent  such  employment  would  have been taken into
account under the Cognizant Career  Transition Plan as in existence  immediately
prior to the Spinoff Date.

Section 2 - SEVERANCE BENEFITS

       2.1 Subject to the  provisions of this Section 2 (including the condition
set  forth in  Section  2.4),  in the  event of an  Eligible  Termination  by an
Eligible Employee:

       (a) If the  Eligible  Termination  occurs  not within a Change in Control
Period, the Eligible Employee shall be entitled to receive from the Company or a
Participating  Company  the  Salary  continuation  and  benefits  in the  amount
determined  in  accordance  with  Attachment  C  for  the  period  specified  on
Attachment B hereto, subject to Section 2.2 and 2.3; and

       (b) If the  Eligible  Termination  occurs  within  the  Change in Control
Period, the Eligible Employee shall be entitled to receive from the Company or a
Participating  Company the Salary continuation in an amount equal to 130% of the
amount  determined in accordance with  Attachment C for the period  specified on
Attachment  B hereto and  benefits  for the period  specified  on  Attachment  B
hereto,  subject to Section 2.2 and 2.3; provided,  however, that if the Company
or a  Participating  Company  and the  Eligible  Employee  have  entered  into a
Change-in-Control  Agreement  or  other  agreement  specifically  providing  for
severance payments and benefits upon specified  terminations  following a change
in  control  of the  Company  which is in  effect  at the  date of the  Eligible
Termination (whether or not severance payments and benefits are actually payable
under such other agreement), no Salary continuation or benefits shall be payable
to the Eligible Employee under this Plan.

       2.2 If, during the period that Salary and benefits  continuation is to be
provided under Section 2.1 and Attachment B hereto,  the Eligible Employee earns
or accrues  compensation  and  benefits  under any  employment  or  compensatory
arrangement  for  services  provided  to any 

                                       4

<PAGE>

party  other  than the  Company  or a  Participating  Company  (including  as an
employee,  consultant, owner, partner, associate, agent, independent contractor,
sole  proprietor,  security  holder,  or  otherwise in an  arrangement  in which
anything  of value is  earned  or  accrued  based on  services  of the  Eligible
Employee),  the Salary  continuation  payments and benefits  continuation  shall
terminate as of the date such services  commenced.  The Eligible  Employee shall
inform  the  Employee  Benefits  Committee  of  any  such  employment  or  other
arrangement  under  which  such  services  will be  provided,  prior  to or upon
commencement of such  employment or arrangement,  including the date as of which
such employment or services  commenced.  The Company or a Participating  Company
shall be entitled to recover  from the  Eligible  Employee  any payments and the
fair market  value of  benefits  previously  made or  provided  to the  Eligible
Employee under the Plan which would not have been paid under this Section 2.2 if
the  Employee  Benefits  Committee  had  adequate  prior  notice of the  matters
specified  in the  preceding  sentence.  If,  during the period  that Salary and
benefits  continuation  is to be provided  under  Section 2.1 and  Attachment  B
hereto,   the  Eligible  Employee  becomes   reemployed  by  the  Company  or  a
Participating Company or enters into a compensation arrangement with the Company
or a  Participating  Company  not  contemplated  at  the  time  of  his  or  her
termination,  Salary and benefits  continuation  hereunder will continue only if
and  to  the  extent  determined  by  the  Employee  Benefits   Committee.   All
determinations  under this Section 2.2 shall be made in the sole  discretion  of
the Employee Benefits Committee.

       2.3 Unless otherwise  determined by the Employee Benefits Committee,  the
amount of Salary  payable  during the period  specified in Attachment B shall be
reduced by each of the  following  amounts,  if any,  applicable to the Eligible
Employee  (but not reduced to an amount less than zero  pursuant to this Section
2.3):

       (i)    the amount of any sign-on bonus or any other amount(s) paid by the
              Company or any of its affiliated entities to the Eligible Employee
              (other  than  the  payment  of  base  salary,  performance-related
              bonuses, or reimbursement of business-related expenses incurred by
              the Eligible Employee) in connection with the Eligible  Employee's
              commencement  of employment,  if such  payment(s)  occurred within
              twelve months of the date of the Eligible Termination, or

       (ii)   the amount of any severance payments,  termination payments or any
              other  amounts  paid or payable to the Eligible  Employee  arising
              from or relating to the  termination of employment of the Eligible
              Employee  by the  Company or any  affiliated  entity,  whether the
              rights to such payments  arise from (a) severance or other benefit
              plans sponsored by the Company or any of its affiliated  entities,
              (b) the laws of any governmental  entity,  (c) the requirements of
              any works council or labor  organization,  or (d) the terms of any
              agreement between the Eligible Employee and the Company and/or any
              of its affiliated entities.

If reduced in accordance  with this Section 2.3, the aggregate  amount of Salary
payable  during the period  specified in  Attachment B shall equal the aggregate
amount of Salary  that would have been  payable  over the entire  period  (i.e.,
before any reduction) minus the amount referred to in clause (i) of this Section
and minus the amount referred to in clause (ii) of this Section.  Such aggregate
amount of Salary shall be payable  proportionately  over the period during which
Salary continuation is to be paid, as specified in Attachment B hereto.

                                       5

<PAGE>

       2.4 The grant of  severance  benefits  pursuant  to Section 2.1 hereof is
conditioned  upon an  Eligible  Employee's  signing a  Severance  Agreement  and
Release and the expiration of any revocation period set forth therein.

       2.5  Notwithstanding  any other provision contained herein (except as set
forth in this Section  2.5),  the Chief  Executive  Officer of the Company or an
officer to whom the Chief Executive Officer has delegated  authority may, at any
time, take such action as such officer, in such officer's sole discretion, deems
appropriate to reduce or increase by any amount the benefits  otherwise  payable
to an Eligible Employee pursuant to Section 2.1, including the amount payable as
Salary  during the period  specified in  Attachment  B, or otherwise  modify the
terms and conditions applicable to an Eligible Employee under this Plan provided
that the Chief  Executive  Officer or such  delegatee  reports any  reduction or
increase in benefits or other modification of the terms and conditions hereof to
the Employee  Benefits  Committee.  Notwithstanding  the  foregoing,  during the
Change in Control Period,  the Chief Executive Officer and any delegatee may not
reduce by any amount the  benefits  otherwise  payable to an  Eligible  Employee
pursuant  to  Section  2.1(b) or  otherwise  modify  the  terms  and  conditions
applicable to an Eligible  Employee under the Plan.  Benefits granted  hereunder
may not exceed an amount nor be paid over a period which would cause the Plan to
be other  than a "welfare  benefit  plan"  under  section  3(1) of the  Employee
Retirement Income Security Act of 1974, as amended ("ERISA").

       2.6 In the event the  Company  or a  Participating  Company,  in its sole
discretion,  grants an Eligible  Employee a period of inactive  employee status,
any amounts paid to such Eligible  Employee  during any such period shall offset
the benefits  payable  under this Plan if the Eligible  Employee does not resume
active employment prior to termination of employment. For this purpose, a period
of inactive  employee  status  shall mean the period  beginning on the date such
status  commences (of which the Eligible  Employee shall be notified) and ending
on the date of such Eligible Employee's  termination of employment or resumption
of active employment.

Section 3 - AMENDMENT AND TERMINATION

       3.1 The Company  reserves the right to terminate the Plan at any time and
without any further obligation by action of its Board of Directors or such other
person or persons to whom the Board properly delegates such authority; provided,
however,  during a Change in Control  Period,  the Company may not terminate the
Plan.

       3.2 The Company  shall have the right to modify or amend the terms of the
Plan at any time, or from time to time, to any extent that it may deem advisable
by action of its Board of  Directors,  the  Committee  or such  other  person or
persons  to  whom  the  Board  or the  Committee  properly  has  delegated  such
authority;  provided,  however,  that  during a Change in  Control  Period,  the
Company may not modify or amend the terms of the Plan in a manner which  reduces
the compensation or benefits otherwise payable hereunder;  and provided further,
that the Company may not modify or amend the terms of the Plan in a manner which
materially adversely affects the rights of a person who has commenced to receive
compensation or benefits hereunder following an Eligible Termination.

                                       6

<PAGE>

       3.3 All modifications of or amendments to the Plan shall be in writing.

Section 4 - ADMINISTRATION OF THE PLAN

       4.1 The Employee Benefits  Committee shall be the Plan  Administrator and
shall have the exclusive right, power and authority to:

       (a)    construe and interpret any and all of the provisions of the Plan;

       (b)    establish a claims and appeals procedure; and

       (c)    consider and decide conclusively any questions (whether of fact or
              otherwise)  arising in connection with the  administration  of the
              Plan or any claim for Salary  and  benefits  continuation  arising
              under the Plan.

Any  decision  or action of the  Employee  Benefits  Committee  pursuant to this
Section 4.1 shall be in the sole discretion of the Employee  Benefits  Committee
and shall be conclusive and binding on any affected person.

       4.2 With respect to any function of the Employee Benefits Committee under
the Plan, the Employee Benefits Committee may, in its sole discretion,  delegate
its authority under the Plan to any employee(s) or committee of employees of the
Company or  Participating  Companies,  and may  designate  such  employee(s)  or
committee to function as or act on behalf of the Employee Benefits Committee.

       4.3 The Company shall indemnify any individual who is a director, officer
or  employee  of the  Company  or any  affiliate,  or his or her heirs and legal
representatives, against all liability and reasonable expense, including counsel
fees,  amounts paid in settlement and amounts of judgments,  fines or penalties,
incurred or imposed upon him or her in connection with any claim,  action,  suit
or proceeding,  whether civil,  criminal,  administrative or  investigative,  in
connection  with his or her duties with respect to the Plan,  provided  that any
act or omission giving rise to such claim,  action,  suit or proceeding does not
constitute willful misconduct or is not performed or omitted in bad faith.

Section 5 - MISCELLANEOUS

       5.1 Neither the  establishment  of the Plan nor any action of the Company
or a Participating  Company,  the Committee,  Employee Benefits Committee or any
fiduciary  shall be held or  construed to confer upon any person any legal right
to continue employment with the Company. The Company and Participating Companies
expressly  reserve the right to discharge any employee  whenever the interest of
the Company or a Participating  Company,  in its sole judgment,  may so require,
without any liability on the part of the Company or a Participating Company, the
Committee, Employee Benefits Committee or any fiduciary.

       5.2  Benefits  payable  under the Plan  shall be paid out of the  general
assets  of  the  Company  or  a  Participating  Company.  The  Company  and  any
Participating  Company  need not 

                                       7

<PAGE>

fund the benefits payable under this Plan; however,  nothing in this Section 5.2
shall be interpreted as precluding the Company or any Participating Company from
funding or setting aside amounts in  anticipation  of paying such benefits.  Any
benefits  payable to an Eligible  Employee  under this Plan shall  represent  an
unsecured  claim by such  Eligible  Employee  against the general  assets of the
Company or the Participating Company that employed such Eligible Employee.

       5.3 The Company or a  Participating  Company shall deduct from the amount
of any Salary  continuation or other benefits payable hereunder amounts required
by law to be withheld for the payment of any taxes and any other amount properly
to be withheld.

       5.4 Benefits  payable under the Plan shall not be subject to  assignment,
alienation,  transfer, pledge,  encumbrance,  commutation or anticipation by the
Eligible Employee. Any attempt to assign, alienate,  transfer, pledge, encumber,
commute or anticipate Plan benefits shall be void.

       5.5 This Plan shall be governed by and construed in  accordance  with the
laws of the State of New Jersey,  without  regard to  principles of conflicts of
laws, except to the extent superseded by applicable federal law.

       5.6 This Plan will be of no force or effect to the extent  superseded  by
foreign law. In  addition,  the terms and  conditions  of  participation  of any
Eligible  Employee  whose  employment  is  subject to the laws or customs of any
jurisdiction  other than the United States or a state thereof may be modified by
the Employee  Benefits  Committee  to conform to or otherwise  take into account
such laws and customs; in no event shall severance benefits be payable hereunder
if and to the extent  that such  benefits  would  duplicate  severance  benefits
payable in accordance with such laws and customs,  although  severance  benefits
payable hereunder may supplement those payable under such laws and customs.

       5.7  This  Plan  supersedes  any and all  prior  severance  arrangements,
policies, plans or practices of the Company and any predecessor (whether written
or  unwritten),  including any severance  arrangement  described in any document
setting forth an offer of employment.  Notwithstanding  the preceding  sentence,
the Plan does not affect the severance  provisions of (i) any written individual
employment  agreement  between an employee  and the  Company or a  Participating
Company which results in such employee not being an Eligible Employee hereunder;
(ii) any  Change-in-Control  Agreement or other agreement referred to in Section
2.1(b);  and (iii) any other agreement  entered into between an employee and the
Company or a  Participating  Company after the effective date of this Plan which
expressly supersedes the provisions of this Plan (i.e., by naming this plan) and
which  remains  in  effect  at  the  date  of  such  employee's  termination  of
employment.  Benefits  payable  under  the Plan  shall be  offset  by any  other
severance or termination  payment made by the Company or any of its subsidiaries
including, but not limited to, amounts paid pursuant to any agreement or law.

       5.8 This Plan shall be effective as of December 1, 1998.

Incorporated  (the "Company"),  an employee of the Company or any  Participating
Company (as defined in the Plan) who is an Eligible  Employee (as defined in the
Plan) shall be assigned to the  Designated  Group in  accordance  with the chart

                             IMS HEALTH INCORPORATED

                            EMPLOYEE PROTECTION PLAN

        Certain Terms and Conditions of Salary and Benefits Continuation


       An Eligible Employee entitled to salary and benefits  continuation  under
the  Employee  Protection  Plan (the  "Plan")  of IMS Health  Incorporated  (the
"Company")  shall,  subject to Section 2 of the Plan,  receive the  payments and
benefits  specified below.  Capitalized  terms used but not defined herein shall
have the meanings as defined in the Plan.

       1.     Salary Continuation

       The Eligible  Employee shall receive Salary  continuation  for the period
specified  under  Section 2 of the Plan and  Attachment  B thereto  (the "Salary
Continuation Period").  Salary continuation hereunder shall be paid at the times
during such Salary Continuation Period the Eligible Employee's salary would have
been paid if employment had not  terminated.  Solely for purposes of determining
the  amount  payable  during  the  Salary  Continuation  Period and for no other
purposes  of the  Plan,  the  Employee  Benefits  Committee  may,  in  its  sole
discretion,  include an  additional  cash amount as part of the amount of Salary
continuation,  in order to  reflect  any  periodic  payment  being  received  as
compensation by the Eligible Employee in addition to Salary immediately prior to
termination  and to ensure  comparability  of benefits among Eligible  Employees
receiving benefits under the Plan. All Salary and benefit continuation  payments
shall be subject to termination upon  commencement of employment or services and
otherwise as provided in Section 2.2 of the Plan.

       2.     Welfare Benefit Continuation

       Medical,  dental and life insurance benefits shall be provided throughout
the Salary Continuation Period at the levels in effect for the Eligible Employee
immediately  prior to termination of employment but in no event greater than the
levels in effect for active employees  generally during the Salary  Continuation
Period,  provided that the Eligible  Employee shall pay the employee  portion of
any required premium payments at the level in effect for employees  generally of
the  Company  for  such  benefits.  For  purposes  of  determining  an  Eligible
Employee's entitlement to continuation coverage as required by Title I, Subtitle
B, Part 6 of ERISA,  such employee's  18-month or other period of coverage shall
commence on his or her termination of employment.

       3.     Annual Bonus Payment

       Subject  to the  provisions  of this  paragraph  3, a cash  bonus for the
calendar  year of  termination  shall  be paid if the  Eligible  Employee  was a
participant in the annual bonus plan of the Company or a 


<PAGE>

Participating  Company  (the  "Annual  Incentive  Plan")  immediately  prior  to
termination of employment and the Eligible  Employee was employed by the Company
or a Participating Company for at least six full months during the calendar year
of termination. In such event, the Eligible Employee shall receive a cash amount
equal to the actual bonus which would have been payable to the Eligible Employee
under such Annual Incentive Plan had such employee remained employed through the
end of the year of such  termination  multiplied  by a fraction the numerator of
which is the number of full months of  employment  during the  calendar  year of
termination  and the  denominator of which is 12. Such bonus shall be payable at
the time  otherwise  payable under the Annual  Incentive Plan had employment not
terminated.  The  foregoing  notwithstanding,  (i) no amount shall be paid under
this  paragraph  in  the  event  the  Eligible  Employee  incurred  an  Eligible
Termination by reason of unsatisfactory performance, unless otherwise determined
by the Employee  Benefits  Committee or, in the case of an executive  officer of
the Company,  by the Compensation and Benefits  Committee of the Company's Board
of Directors, and (ii) no amount shall be paid under this paragraph in the event
that Salary and  benefits  continuation  has  previously  ceased by operation of
Section 2.2 of the Plan.  The terms of this  paragraph 3 supersede  those of any
Annual  Incentive  Plan,  so that no payment  shall be made  under  such  Annual
Incentive Plan to an Eligible Employee following an Eligible  Termination except
as provided  hereunder.  The foregoing  provisions of this  paragraph 3 shall be
appropriately  modified  in the  case of any  plan  providing  bonuses  based on
12-month performance periods other than the calendar year.

       4.     Long-Term Bonus Payments and Other Compensation Plans

       Bonus payouts  under any bonus plan with a  performance  cycle of greater
than one year (the "Long-Term  Plan") of the Company or a Participating  Company
in which the Eligible  Employee  participates  immediately  prior to termination
shall be determined and governed in accordance  with the terms of such Long-Term
Plan. Payments, forfeitures, and other events under any compensatory plan, other
than those  referred to in  paragraphs  1 through 4 hereof,  of the Company or a
Participating  Company shall be determined  and governed in accordance  with the
terms of such plan.

       5.     Death

       Upon the death of an  Eligible  Employee  during the Salary  Continuation
Period,  the benefits  described in paragraphs  1, 3 and 4 of this  Attachment C
shall continue to be paid to his or her estate,  as  applicable,  at the time or
times otherwise provided for herein.

       6.     Other Benefits

       The Eligible  Employee  shall be entitled to such  outplacement  services
during the Salary  Continuation  Period as may be  provided  by the Company or a
Participating  Company.   During  the  Salary  Continuation  Period,   financial
planning/counseling  shall be  afforded  to the  Eligible  Employee  to the same
extent afforded  immediately prior to termination of employment in the event the
Eligible  Employee  incurred  an  Eligible  Termination  other than by reason of
unsatisfactory performance.

       7.     No Further Grants, Etc.

                                       2

<PAGE>


       Following an Eligible  Employee's  termination of employment,  no further
grants, awards,  contributions,  accruals or continued  participation (except as
otherwise  provided for herein)  shall be made to or on behalf of such  employee
under any plan or program maintained by the Company  including,  but not limited
to,  any  Annual  Incentive  Plan,  any  Long-Term  Plan  or  any  qualified  or
nonqualified  retirement,  profit sharing, stock option or restricted stock plan

                         SEVERANCE AGREEMENT AND RELEASE

       THIS SEVERANCE AGREEMENT AND RELEASE, made by and between _______________
(hereinafter   referred  to  as   "Employee"),   and  IMS  Health   Incorporated
(hereinafter  deemed to include its worldwide  subsidiaries  and  affiliates and
referred to as the "Company").

                                WITNESSETH THAT:

       WHEREAS,  Employee has been  employed by the Company  and/or a previously
affiliated company or other predecessor since the date specified in the Appendix
to this Agreement (the "Appendix"); and

       WHEREAS,  the parties to this Agreement desire to enter into an agreement
in order to provide certain salary and benefits continuation to Employee;

       NOW,  THEREFORE,  in  consideration  of the mutual covenants and promises
hereinafter  set forth and of the actions taken  pursuant  thereto,  the parties
agree as follows:

       1. Employee's service with the Company,  including  Employee's service as
an officer and Employee's membership on any committees,  is terminated effective
on the date specified in the Appendix. By execution of this Agreement,  Employee
confirms his or her resignation from all such offices and committees,  effective
as of the date  specified as "Effective  Date of  Termination of Service" in the
Appendix.

       2.  Effective on the date set forth in the Appendix,  Employee will incur
an "Eligible  Termination" under the IMS Health Incorporated Employee Protection
Plan  (the  "Plan"),  a  summary  plan  description  of  which  Employee  hereby
acknowledges having received, and will,  accordingly,  be entitled to the salary
and benefits continuation  specified therein subject to the terms and conditions
of such Plan. A summary of the benefits to which  Employee is entitled under the
Plan is set forth in the Appendix.  Subject to the terms of the Plan, the salary
and benefits continuation shall be provided during the "Severance Period," which
shall extend from the date of the Eligible Termination until the earliest of (i)
the "Severance Termination Date" specified in the Appendix, (ii) the termination
of salary continuation and benefits under Section 2.2 of the Plan as a result of
the eligible  Employee  earning or accruing  compensation  from a third party or
otherwise  under  Section  2.2, or (iii)  cessation of salary  continuation  and
benefits  under any other  provision  of the Plan or this  Agreement  (including
paragraph 8 hereof).  Subject to the terms of the Plan,  Employee's  obligations
under  paragraphs  3, 4 and 5 of this  Agreement  shall be in effect  during the
"Obligation   Period,"  which  shall  extend  from  the  date  of  the  Eligible
Termination until the later of (i) the "Severance Termination Date" specified in
the  Appendix  (whether or not the  Severance  Period  expires  earlier than the
Severance  Termination  Date) or (ii) the first  anniversary  of the date of the
Eligible Termination.

       3. Employee agrees that , during the Obligation Period,  Employee will be
reasonably  available  to  consult on  matters,  and will  cooperate  fully with
respect to any claims,


<PAGE>

litigations or  investigations,  relating to the Company.  No reimbursement  for
expenses  incurred  after  the  commencement  of a period of  inactive  employee
status, or if there is no such period, after termination of employment, shall be
made to Employee unless authorized in advance by the Company.

       4. Employee agrees that, during the Obligation Period,  Employee will not
become an employee, officer, director, member, consultant, or holder of stock or
other  security  (unless  such stock or other  security  is listed on a national
securities  exchange or traded on a daily basis in the  over-the-counter  market
and  Employee's  ownership  interest is not in excess of 2% of the company whose
stock  or  other  securities  are  being  acquired),  of  or  to a  corporation,
partnership  or any  other  business  or firm,  which  competes  with any of the
businesses owned or operated by the Company; nor, if Employee becomes associated
with  a  company,  partnership  or  individual  which  company,  partnership  or
individual  acts as a consultant to businesses in competition  with the Company,
will Employee  provide services to such competing  businesses.  Businesses which
compete with the Company include,  but are not limited to, businesses engaged in
[specify  nature  of  business]  ,  including  [specify   companies]  and  their
affiliates  and  successors  thereto.   The  restrictions   against  competition
contained  in this  paragraph  shall apply in any state of the United  States in
which the Company was doing  business at the time of Employee's  termination  of
employment and in any territory in which,  in the six months prior to Employee's
termination of employment, Employee participated in or had responsibilities with
respect to Company operations in such territory.  The restrictions  contained in
this  paragraph  shall  apply  whether  or not  Employee  accepts  any  form  of
compensation  from such  competing  entity or  consultant.  Employee also agrees
that,  during the  Obligation  Period,  Employee will not recruit or solicit any
customers  of the  Company to become  customers  of any  business  entity  which
competes  with  any of the  businesses  owned or  operated  by the  Company.  In
addition,  Employee agrees that, during the Obligation Period,  neither Employee
nor any company or entity Employee controls or in which Employee participates in
management,  shall  recruit or solicit any  employee of the Company to become an
employee of any business entity.

       5. If, during the Obligation  Period,  Employee performs services for any
party other than the  Company or a  Participating  Company  (whether or not such
entity is in competition with the Company), Employee shall notify the Company by
certified mail prior to the commencement  thereof,  and the salary  continuation
payments and benefits continuation provided under the Plan shall terminate as of
the date such services commence.  To "perform services" shall mean employment or
other service as an employee,  consultant,  owner,  partner,  associate,  agent,
independent  contractor,  sole proprietor,  security holder,  or otherwise in an
arrangement in which anything of value is earned or accrued based on services of
the Eligible Employee.

       6. Employee agrees that Employee will not directly or indirectly disclose
any  proprietary  or  confidential   information,   records,   data,   formulae,
specifications  and other trade  secrets  owned or held by the Company,  whether
oral or written,  to any person or use any such information,  except pursuant to
court order (in which case  Employee will first provide the Company with written
notice of  such).  All  records,  files,  drawings,  documents,  models,  disks,
equipment  and the like  relating to the  businesses of the Company shall remain
the sole  property of the Company and shall not be removed  from the premises of
the Company.  Employee  further  agrees to return to the Company any property of
the Company which  Employee may have, no matter where  located,  and not to keep
any copies or portions thereof.


<PAGE>

       7. Employee shall not make any derogatory or defamatory  statements about
the Company and shall not make any written or oral  statement,  news  release or
other announcement  relating to Employee's employment by the Company or relating
to the Company  (including  its  affiliates),  customers or personnel,  which is
designed to embarrass or criticize any of the foregoing.

       8.  Employee  agrees  that in the event of any  breach  of the  covenants
contained in paragraphs 3, 4, 5, 6 or 7, in addition to any remedies that may be
available to the Company, the Company may cease all payments and cease providing
all other  benefits  required to be made or provided to Employee  under the Plan
and recover all such  payments  and the fair market  value of all such  benefits
previously  made to Employee  pursuant to the Plan.  The parties  agree that any
such  breach  would cause  injury to the  Company  which  cannot  reasonably  or
adequately be quantified  and that such relief does not  constitute in any way a
penalty or a forfeiture.

       9. Employee, for Employee, Employee's family, representatives, successors
and assigns,  releases and forever  discharges  the Company and its  successors,
assigns, subsidiaries,  affiliates,  directors, officers, employees,  attorneys,
agents and  trustees  or  administrators  of any  Company  plan from any and all
claims,  demands, debts, damages,  injuries,  actions or rights of action of any
nature whatsoever,  whether known or unknown, which Employee had, now has or may
have against the Company,  its successors,  assigns,  subsidiaries,  affiliates,
directors, officers, employees, attorneys, agents and trustees or administrators
of any  Company  plan,  from  the  beginning  of  Employee's  employment  to and
including the date of this  Agreement,  relating to or arising out of Employee's
employment with the Company or the  termination of such employment  other than a
claim with respect to a vested right Employee may have to receive benefits under
any plan  maintained by the Company.  Employee  represents that Employee has not
filed any  action,  complaint,  charge,  grievance  or  arbitration  against the
Company or any of its successors, assigns, subsidiaries,  affiliates, directors,
officers,  employees,  attorneys,  agents and trustees or  administrators of any
Company plan.

       10.  Employee  covenants  that neither  Employee,  nor any of  Employee's
respective  heirs,  representatives,   successors  or  assigns,  will  commence,
prosecute or cause to be commenced or  prosecuted  against the Company or any of
its  successors,   assigns,  subsidiaries,   affiliates,   directors,  officers,
employees,  attorneys, agents and trustees or administrators of any Company plan
any action or other proceeding based upon any claims, demands, causes of action,
obligations,  damages or liabilities which are being released by this Agreement,
nor will Employee seek to challenge the validity of this Agreement,  except that
this  covenant  not to sue does not affect  Employee's  future  right to enforce
appropriately the terms of this Agreement in a court of competent jurisdiction.

       11. Employee  acknowledges  that (a) Employee has been advised to consult
with an attorney at Employee's own expense  before  executing this Agreement and
that Employee has been advised by an attorney or has knowingly waived Employee's
right to do so, (b) Employee has had a period of at least [twenty-one (21) days]
[forty-five (45) days] within which to consider this Agreement, (c) Employee has
a period  of seven (7) days from the date that  Employee  signs  this  Agreement
within which to revoke it and that this Agreement  will not become  effective or
enforceable  until the expiration of this seven (7) day revocation  period,  (d)
Employee fully 

                                       3

<PAGE>

understands  the terms and contents of this  Agreement and freely,  voluntarily,
knowingly  and without  coercion  enters into this  Agreement,  (e)  Employee is
receiving  greater  consideration  hereunder  than  Employee  would  receive had
Employee not signed this Agreement and that the consideration hereunder is given
in exchange  for all of the  provisions  hereof and (f) the waiver or release by
Employee  of rights or claims  Employee  may have  under  Title VII of the Civil
Rights Act of 1964, The Employee Retirement Income Security Act of 1974, the Age
Discrimination  in Employment Act of 1967, the Older Workers Benefit  Protection
Act, the Fair Labor  Standards  Act, the Americans  with  Disabilities  Act, the
Rehabilitation  Act, the Worker  Adjustment  and Retraining Act (all as amended)
and/or any other  local,  state or federal law dealing  with  employment  or the
termination thereof is knowing and voluntary and, accordingly,  that it shall be
a breach of this  Agreement  to  institute  any action or to recover any damages
that  would  be in  conflict  with or  contrary  to this  acknowledgment  or the
releases Employee has granted  hereunder.  Employee  understands and agrees that
the  Company's  payment of money and other  benefits to Employee and  Employee's
signing of this  Agreement  does not in any way indicate  that  Employee has any
viable  claims  against  the Company or that the  Company  admits any  liability
whatsoever.

       12. This Agreement  constitutes  the entire  agreement of the parties and
all prior negotiations or representations are merged herein. It shall be binding
upon and shall inure to the benefit of the parties  hereto and their  respective
successors, assigns, heirs and legal representatives, but neither this Agreement
nor any rights  hereunder shall be assignable by Employee  without the Company's
written consent. In addition,  this Agreement supersedes any prior employment or
compensation  agreement,  whether written,  oral or implied in law or implied in
fact between Employee and the Company, other than those contracts and agreements
excepted from the  application  of Section 5.7 of the Plan pursuant to the terms
of such Section [(but subject to paragraph 15 hereof)],  which prior  agreements
are hereby terminated.

       13. If for any reason any one or more of the provisions of this Agreement
shall be held or deemed to be inoperative,  unenforceable  or invalid by a court
of  competent  jurisdiction,  such  circumstances  shall not have the  effect of
rendering  such  provision  invalid  in any other  case or  rendering  any other
provisions of this Agreement inoperative, unenforceable or invalid.

       14. This Agreement  shall be construed in accordance with the laws of the
State of New Jersey, except to the extent superseded by applicable federal law.

       15. This Agreement  shall terminate in its entirety the Change in Control
Agreement between the Company and Employee. [USE PROVISION IF APPLICABLE]

       IN WITNESS  WHEREOF,  Employee and IMS Health  Incorporated,  by its duly
authorized agent, have hereunder executed this Agreement.

<PAGE>


Section  162(m) of the Code (or any successor  section  thereto).  The Committee
shall have the authority to select the employees to be granted  Awards under the
Plan,  to determine the size and terms of an Award  (subject to the  limitations
imposed on Awards in Section 5 below), to modify the terms of any Award that has
been granted (except for any modification  that would increase the amount of the
Award payable to a Covered Participant),  to determine the time when Awards will
be  made  and  the  Performance  Period  to  which  they  relate,  to  establish
performance  objectives  in respect of such  performance  periods and to certify
that such performance objectives were attained; provided, however, that any such
action shall be consistent  with the applicable  provisions of Section 162(m) of
the Code. 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

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. Determinations made by the Committee under the
Plan need not be uniform and may be made selectively among Participants, whether
or not such  Participants are similarly  situated.  The Committee shall have the
right to deduct from any payment made under the Plan any federal,  state,  local
or foreign  income or other taxes required by law to be withheld with respect to
such payment. To the extent consistent with the applicable provisions of Section

pursuant to the Plan.

material  impact on the  results of the  operations  of the Company or of one or
more  of  its  Subsidiaries.   The  designation  of  Participants  may  be  made
individually  or by groups or  classifications  of  employees,  as the Committee
deems appropriate.

     (a) Performance  Goals. A Participant's  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  than 90 days,  the  number  of days  which is equal to 25
percent of the relevant Performance Period. The performance goals, which must be
objective with respect to Covered Participants,  shall be based upon one or more
of the  following  criteria:  (i)  consolidated  earnings  before or after taxes
(including earnings before 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) return on assets;
(xix) customer satisfaction;  and (xx) employee satisfaction.  In addition, with
respect to  Participants  who are not Covered  Participants,  the  Committee may
approve  performance  goals  based on other  criteria,  which  may or may not be
objective.  The foregoing criteria may relate to the Company, one or more of its
Subsidiaries  or one  or  more  of its  divisions,  units,  partnerships,  joint
venturers or minority investments,  product lines or products 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.  The maximum
amount  of an Award to any  Participant  with  respect  to a fiscal  year of the
Company shall be $3,000,000.

     (b) Payment.  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  Award.  No Awards will be paid for such  performance  period
until  such  certification  is made by the  Committee.  The  amount of the Award
actually  paid  to  a  given  Participant  may  be  less  or,  with  respect  to
Participants who are not Covered  Participants,  more than the amount determined
by the applicable  performance goal formula, at the discretion of the Committee.
The amount of the Award  determined by the  Committee  for a performance  period
shall be paid to the


                                       5


<PAGE>


Participant  at such time as determined by the Committee in its sole  discretion
after the end of such Performance Period.

     (c)  Termination  of  Employment.  If a  Participant  who is not a  Covered
Participant dies,  retires,  is assigned to a different  position,  is granted a
leave of absence,  or if the  Participant's  employment is otherwise  terminated
(except with cause by the Company) during a Performance Period, a pro rata share
of the Participant's  award based on the period of actual  participation may, at
the  Committee's  discretion,  be paid to the  Participant  after the end of the
Performance  Period  if  it  would  have  become  earned  and  payable  had  the
Participant's employment status not changed.

     (d)  Compliance  with Section  162(m) of the Code.  The  provisions of this
Section 5 shall be  administered  and  interpreted  in  accordance  with Section
162(m)  of  the  Code  to  ensure  the  deductibility  by  the  Company  or  its
Subsidiaries of the payment of Awards.

6.   Amendments or Termination

     The Board may  amend,  alter or  discontinue  the Plan,  but no  amendment,
alteration or discontinuation shall be made which would impair any of the rights
or obligations  under any Award  theretofore  granted to a Participant under the
Plan without such Participant's consent;  provided,  however, that the Committee
may amend the Plan in such manner as it deems  necessary  to permit the granting
of  Awards  meeting  the  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)(ii) of the Plan after
the occurrence of a Change in Control.

7.   No Right to Employment

     Neither  the Plan nor any action  taken  hereunder  shall be  construed  as
giving any  Participant  or other person any right to continue to be employed by
or  perform  services  for the  Company  or any  Subsidiary,  and the  right  to
terminate the employment of or performance of services by any Participant at any
time  and for  any  reason  is  specifically  reserved  to the  Company  and its
Subsidiaries.

8.   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.

9.   Reduction of Awards

     Notwithstanding anything to the contrary herein, the Committee, in its sole
discretion  (but subject to applicable  law), may reduce any amounts  payable to
any  Participant  hereunder  in order to  satisfy  any  liabilities  owed to the
Company or any of its Subsidiaries by the Participant.

10.  Adjustments Upon Certain Events

     (a)  Generally.  In the event of any  change in the  outstanding  Shares by
reason of any Share dividend or split, reorganization, recapitalization, merger,
consolidation,  spin-off,  combination or exchange of Shares or other  corporate
exchange,  or any distribution to stockholders of Shares other than regular cash
dividends,  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 any affected terms of outstanding Awards.

     (b) Change in Control.  Notwithstanding  any other provision in the Plan to
the contrary, in the event of a Change in Control, (i) 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,  (A) the  acceleration of an Award, (B) the payment of a cash amount
in exchange for the  cancellation  of an Award  and/or (C) 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 and (ii) any Participant who, as a
result of a Change in Control, receives payments pursuant to a Change-in-Control
agreement  shall receive,  subject to the same terms and conditions  under which
such  payments are made,  an amount in cash equal to (A) the annual target bonus
under the Plan for the year in which the Change in Control occurs, multiplied by
a fraction, (I) the numerator of which equals the number of full or partial days
in such annual  performance  period  during  which he or she was employed by the
Company  and (II) the  denominator  of which is 365,  and (B) the entire  target
bonus  opportunity  with  respect to all other  performance  periods in progress
under this Plan at the time of his or her  termination  of  employment  from the
Company.

11.  Miscellaneous Provisions

     The Company is the sponsor and legal  obligor under the Plan and shall make
all  payments  hereunder,  other  than  any  payments  to be  made by any of the
Subsidiaries (in


                                       7


<PAGE>


which case shall be made by such Subsidiary, as appropriate).  The Company shall
not be required to establish  any special or separate  fund or to make any other
segregation  of assets to ensure the payment of any amounts under the Plan,  and
the  Participants'  rights to the payment hereunder shall be no greater than the
rights of the  Company's (or  Subsidiary's)  unsecured  creditors.  All expenses
involved in administering the Plan shall be borne by the Company.

12.  Choice of Law

     The Plan shall be governed by and construed in accordance  with the laws of

              immediately  following the date of such  election  (the  "Election

              (in which case  Section 3.4 (d) shall  apply) and (ii) such Member
              complies  with  the  administrative  procedures  set  forth by the

              Plan to be received in a lump sum as follows:  0%, 25%,  50%, 75%,
              or 100%.

       further benefits,  as the case may be, shall be paid to a

3.7    Repayment of Benefits Paid as Lump Sum.

       (a)    Subject to Section 3.8 hereof,  a Member or Vested  Former  Member
              who  receives in a lump sum any  portion of his or her  Retirement
              Benefit  or  Deferred  Vested  Benefit  pursuant  to  a  Lump  Sum
              Election,  shall receive such lump sum portion of such  Retirement
              Benefit or Deferred  Vested Benefit  subject to the condition that
              if such Member or Vested Former Member  engages in any of the acts
              described  in Section  3.5(a),  then such Member or Vested  Former
              Member shall,  within 60 days after written notice by the Company,
              repay to the Company the amount described in Section 3.7(b).

       (b)    The amount described in this section shall equal the amount of the
              Member's or Vested  Former  Member's  lump sum benefit  paid under
              this Plan to which such Member or Vested  Former  Member would not
              have been  entitled,  if such lump sum benefit  had  instead  been
              payable in the form of an annuity under this Plan and such annuity
              payments were subject to the provisions of Section 3.5.

3.8    Change in Control.  Notwithstanding  anything to the  contrary  contained
       herein,  the  provisions of Sections 3.5 through 3.7 shall be of no force
       or effect from and after a Change in Control  with  respect to any Member
       and Vested  Former Member who is


                                       16
<PAGE>

       employed  by the Company or an  Affiliated  Employer as of such Change in
       Control.

                        SECTION 4 -- DISABILITY BENEFITS

4.1    (a)    Eligibility.  A Member who is enrolled for the maximum  disability
              insurance  coverage  available under the Basic Disability Plan and
              who has  become  Disabled  shall  be  entitled  to the  Disability
              Benefit described in Section 4.1(b).

       (b)    Amount.  The Disability Benefit of a Member entitled thereto shall
              be an annual benefit  payable in monthly  installments  under this
              Plan during the same period as  disability  benefits  are actually
              paid by the Basic  Disability  Plan,  in an amount equal to 60% of
              the Member's  Covered  Earnings,  offset by the Member's (i) Basic
              Disability  Plan Benefit,  (ii) Basic Plan  Benefit,  if the Basic
              Disability  Plan  Benefit  does not already  include an offset for
              such Basic Plan Benefit, and (iii) Other Disability Income.

                    SECTION 5 -- SURVIVING SPOUSE'S BENEFITS

5.1    Death Prior to Benefit Commencement. Upon the death of a Member or Vested
       Former Member, prior to the commencement of his or her Retirement Benefit
       or Deferred Vested Benefit hereunder, his or her Surviving Spouse will be
       entitled to a Surviving  Spouse's Benefit under this Plan equal to 50% of
       the  Retirement or Deferred  Vested Benefit that would have been provided
       from the Plan had the Member or Vested Member  retired from or terminated
       employment  with the  Company or an  Affiliated  Employer  on the date of
       death.

5.2    Death On or After Benefit Commencement. Upon the death of a Vested Former
       Member  while  he or she  is  receiving  Retirement  or  Deferred  Vested
       Benefits,  his or her Surviving Spouse shall 


                                       17
<PAGE>

       receive a Surviving  Spouse's  Benefit  equal to 50% of the Benefit he or
       she was receiving at the time of death. Notwithstanding the foregoing, no
       benefit  shall  be  payable  under  this  Section  5.2  to the  extent  a
       Retirement  Benefit or Deferred  Vested Benefit was previously  paid to a
       Member or Vested Former Member in the form of a lump sum.

5.3    Commencement of Surviving Spouse's Benefit. Except as provided in Section
       5.4, the Surviving  Spouse's  Benefit  provided under Sections 5.1 or 5.2
       will  be  payable  monthly,  commencing  on the  first  day of the  month
       coincident  with or next  following  the date of the  Member's  or Vested
       Former Member's death,  or, if the Member or Vested Former Member had not
       attained  age 55, on the date such Member or Vested  Former  Member would
       have attained age 55 had he or she lived.  Such benefits  shall  continue
       until the first day of the month in which the Surviving Spouse dies.

5.4    Lump Sum Payment.

       (a)    If a Member  or a Vested  Former  Member  made an  Election  under
              Section 3.4 but such Member or Vested  Former Member died prior to
              such lump sum payment,  the  Surviving  Spouse's  Benefit  payable
              under   Section  5.1  hereof  will  be  payable  in  the  form  or
              combination  of forms of  payment  so  elected  by such  Member or
              Vested  Former  Member  pursuant  to such Lump Sum  Election.  The
              amount of any lump sum payment  under the Plan shall be determined
              using the actuarial assumptions set forth in Section 3.4(a).

       (b)    If the lump sum value,  determined  in the same manner as provided
              under Section 3.4(a),  of a Surviving  Spouse's Benefit is $10,000
              or less at the time such  Surviving  Spouse's  Benefit  is payable
              under this Plan, such benefit shall be payable as a lump sum.

                                       18
<PAGE>

       (c)    Any  Surviving  Spouse's  Benefit  which is  payable as a lump sum
              shall be paid  within 60 days  after the date when any  portion of
              such benefit  payable in annuity form  commences or would commence
              if any portion of such Surviving  Spouse's Benefit were payable as
              an annuity as set forth in Section 5.3.

5.5    Reduction.  Notwithstanding  the  foregoing  provisions of Section 5, the
       amount of a Surviving Spouse's Benefit shall be reduced by one percentage
       point for each year (where a half year or more is treated as a full year)
       in excess of ten years that the age of the Member or Vested Former Member
       exceeds the age of the Surviving Spouse.

                             SECTION 6 -- COMMITTEE

6.1    Duties  and  Authority.  The  Committee  shall  be  responsible  for  the
       administration of the Plan and may delegate to any management  committee,
       employee,  director  or  agent  its  responsibility  to  perform  any act
       hereunder,  including,  without  limitation,  those matters involving the
       exercise of discretion;  provided,  that such delegation shall be subject
       to revocation at any time at the  Committee's  discretion.  The Committee
       shall have the authority to determine all questions arising in connection
       with the Plan,  to interpret  the  provisions of the Plan and to construe
       all of its terms, to adopt,  amend, and rescind rules and regulations for
       the  administration  of the Plan, and generally to conduct and administer
       the Plan and to make all  determinations  in connection  with the Plan as
       may be necessary or advisable. All such actions of the Committee shall be
       conclusive and binding upon all Members,  Former  Members,  Vested Former
       Members and Surviving Spouses.

                           SECTION 7 -- MISCELLANEOUS

7.1    Amendment;  Termination.  The  Committee  may,  in its  sole  discretion,
       terminate,  suspend  or amend this Plan at any time or from time to time,
       in whole or in part; provided,  however, that no termination,  suspension
       or  amendment of the Plan may  adversely  affect (a) a Member's or Vested
       Former  Member's  benefit  under the Plan to which he or she is  entitled
       hereunder  or,  (b) a Vested  Former  Member's  right  or the  right of a
       Surviving  Spouse to  receive  or to  continue  to  receive a benefit  in
       accordance  with the Plan,  such  benefits  or rights as in effect on the
       date immediately  preceding the date of such  termination,  suspension or
       amendment.

7.2    No  Employment  Rights.  Nothing  contained  herein  will confer upon any
       Member, Former Member or Vested Former Member the right to be retained in
       the  service  of the  Company  or any  Affiliated  Employee,  nor will it
       interfere  with the right of the  Company or any  Affiliated  Employer to
       discharge or otherwise deal with Members, Former Members or Vested Former
       Members with respect to matters of employment.

7.3    Payout in Discretion of the Committee. Notwithstanding anything herein to
       the contrary,  at any time  following the  termination  of service of the
       Member or Vested  Former  Member,  the  Committee  may  authorize,  under
       uniform  rules  applicable  to all  Members,  Vested  Former  Members and
       Surviving  Spouses under the Plan, a lump sum distribution of a Member's,
       Vested Former Member's and/or Surviving  Spouse's  Retirement  Benefit or
       Surviving  Spouse's  Benefit  under  the Plan in an  amount  equal to the
       present value of such Retirement  Benefit or Surviving  Spouse's Benefit,
       using the actuarial  assumptions  then in use for funding  purposes under
       the IMS Health Incorporated  Retirement Plan, in full satisfaction of all
       present and future Plan  liability  with respect to such  Member,  Vested
       Former  Member  and/or  Surviving  Spouse,  if the amount of such present
       value is less  than  $250,000.  Such  lump sum  



                                       20
<PAGE>

       distribution may be made without the consent of the Member, Vested Former
       Member or Surviving Spouse.

7.4    Unfunded Status.  Members and Vested Former Members shall have the status
       of general unsecured creditors of the Company,  and this Plan constitutes
       a mere  promise by the  Company to make  benefit  payments at the time or
       times  required  hereunder.  It is the intention of the Company that this
       Plan be unfunded  for tax  purposes  and for purposes of Title I of ERISA
       and any trust created by the Company and any assets held by such trust to
       assist the Company in meeting its  obligations  under the Plan shall meet
       the requirements necessary to retain such unfunded status.

7.5    Arbitration.  Any dispute or  controversy  arising under or in connection
       with the Plan shall be settled  exclusively  by  arbitration in New York,
       New  York in  accordance  with  the  rules  of the  American  Arbitration
       Association in effect at the time of such arbitration.  The Company shall
       pay the entire costs of any proceeding brought by a Member, Vested Former
       Member, Former Member, or Surviving Spouse hereunder,  including the fees
       and expenses of counsel and pension experts  engaged by such person,  and
       such  expenses  shall be  reimbursed  promptly  upon  evidence  that such
       expenses  have  been  incurred   without  awaiting  the  outcome  of  the
       proceedings;  provided,  however,  that such costs and expenses  shall be
       repaid  to  the  Company  by  the  recipient  of  same  if it is  finally
       determined by the arbitrators  that the position taken by such person was
       entirely without merit.  Failure of such person to prevail in any dispute
       or  controversy  shall not be the sole basis on which such  determination
       shall be made.

7.6    No  Alienation.  A Member's or Vested  Former  Member's  right to benefit
       payments   under  the  Plan  shall  not  be  subject  in  any  manner  to
       anticipation,    alienation,   sale,   transfer,    assignment,   pledge,
       encumbrance,  attachment  or  garnishment  by creditors or 


                                       21
<PAGE>

       such Member or Vested Former Member or his or her Surviving Spouse.

7.7    Withholding.  The Company may withhold from any benefit under the Plan an
       amount sufficient to satisfy its tax withholding obligations.

7.8    Governing  Law. The Plan shall be governed by and construed in accordance
       with the laws of the State of New York  applicable to contracts  made and
       to be performed in such state to the extent not preempted by federal law.

                             IMS HEALTH INCORPORATED
                             RETIREMENT EXCESS PLAN

                          Effective as of July 1, 1998


                                  Introduction

Effective as of July 1, 1998, the IMS Health Incorporated Retirement Excess Plan
(the  "Plan") is  established  by IMS Health  Incorporated  (the  "Company")  to
provide  participating  employees  with  retirement  benefits in excess of those
permitted  to be paid under the IMS  Health  Incorporated  Retirement  Plan (the
"Qualified Plan") due to the limitations  imposed by Sections 401(a)(17) and 415
of the Internal  Revenue Code of 1986, as amended (the "Code").  For purposes of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),  this
Plan is intended  to be unfunded  and  maintained  primarily  for the purpose of
providing  deferred  compensation  for a select  group of  management  or highly
compensated employees.


<PAGE>



                     Section I -- Participation in the Plan

All  participants in the Qualified Plan shall  participate in this Plan whenever
their  benefits  under the  Qualified  Plan as from time to time in effect would
have exceeded the limitations on benefits imposed by Sections 401(a)(17) and 415
of the Code if such  benefits  were  determined  as  though  no  provision  were
contained in the Qualified Plan incorporating such limitations.



<PAGE>



                             Section II -- Benefits

The Corporation  shall pay to each  participant in the Qualified Plan (or his or
her  beneficiaries  designated to receive  benefits  from the Qualified  Plan) a
benefit equal to the excess of (a) over (b), where:

(a)    equals the amount that would be payable to the participant (or his or her
       beneficiaries)  under the Qualified  Plan in the absence of any provision
       reducing  benefits  due to the  benefit  limitations  imposed by Sections
       401(a)(17) and 415 of the Code; and

(b)    equals the sum of (i) the actual benefits  payable to the participant (or
       his or her  beneficiaries)  from the Qualified Plan and (ii) the benefits
       payable to the participant (or his or her beneficiaries) from the Pension
       Benefit  Equalization  Plan of The Dun &  Bradstreet  Corporation  (as in
       effect on October 31,  1996),  as determined by the Company in accordance
       with the methods and assumptions specified in Appendix A of this Plan.

Notwithstanding the foregoing, no benefits shall be payable hereunder unless the
participant  has a  nonforfeitable  right to benefits under the Qualified  Plan.
Benefits hereunder shall be payable at the same time and in the same form as the
participant's (or his or her beneficiaries')  benefits under the Qualified Plan;
provided,  however,  if an Election  (as defined in Section IV of this Plan) has
been made and becomes  effective prior to the date when benefits under this Plan
would otherwise be payable to the  participant,  the form of payment of benefits
under this Plan shall be in the form so elected pursuant to such Election. If an
Election becomes  effective prior to the date when benefits would be payable and
the  participant  dies prior to the date when benefits would be payable,  his or
her  beneficiaries  designated to receive benefits from the Qualified Plan shall
receive  benefits  in the form so  elected  pursuant  to such  Election.  If the
participant has not designated a beneficiary  under the Qualified Plan, or if no
such beneficiary is living at the time of the  participant's  death, the amount,
if any,  payable  hereunder  upon his or her death shall be  distributed  to the
person or persons who would  otherwise be entitled to receive a distribution  of
the participant's Qualified Plan benefits.

Notwithstanding  any  Election,  if the lump sum value,  determined  in the same
manner as  provided  under  Section  IV below,  of the  benefits  payable to the
participant (or his or her beneficiaries)  under this Plan is $10,000 or less at
the time such  benefits  are payable  under this Plan,  such  benefits  shall be
payable as a lump sum.


<PAGE>



Any portion of the benefits  payable under this Plan as a lump sum shall be paid
commencing  at the same time as  benefits  payable in any other  form  hereunder
would otherwise be paid.


<PAGE>



                         Section III -- Unfunded Status

Participants  hereunder shall have the status of general unsecured  creditors of
the  Company  and this Plan  constitutes  a mere  promise by the Company to make
benefit payments at the time or times required hereunder. It is the intention of
the Company  that this Plan be unfunded  for tax  purposes  and for  purposes of
Title I of ERISA,  and any trust  created by the  Company and any assets held by
such trust to assist the Company in meeting its obligations under the Plan shall
meet the requirements necessary to retain such unfunded status.


<PAGE>



                    Section IV -- Election of Form of Payment

(a)    A  participant  under  this Plan may elect to  receive  all,  none,  or a
       specified portion, as provided below, of his benefits hereunder as a lump
       sum and to receive any balance of such benefits in the form of an annuity
       (an  "Election");  provided that any such Election shall be effective for
       purposes  of  this  Plan  only if (i)  such  participant  remains  in the
       employment  of the  Company  or an  Affiliate,  as the case may be, for a
       period not less than the full 12 calendar  months  immediately  following
       the  Election  Date  of  such  Election  (except  in  the  case  of  such
       participant's  death or  disability  as  provided  below),  and (ii) such
       participant complies with the administrative  procedures set forth by the
       Committee  with respect to the making of an Election.  "Affiliate"  shall
       mean  the  Company  and  any  other  employer  which  is  a  member  of a
       "controlled group of corporations," a group under "common control," or an
       "affiliated service group," all as determined under Code Sections 414(b),
       (c), (m), (o).

(b)    Any  portion of the  benefit  payable to the  participant  (or his or her
       beneficiaries)  in the form of an annuity  shall be paid at the same time
       and in the same form as his or her benefits under the Qualified Plan. Any
       portion  of  the  benefit  payable  to  the  participant  (or  his or her
       beneficiaries)  in the  form of a lump  sum  shall be paid in full at the
       same time as the  benefits  commence  under the  Qualified  Plan,  and no
       subsequent lump sum benefits will be paid.

(c)    A participant  may elect a payment form  different  than the payment form
       previously  elected  by him or her by  filing a  revised  election  form;
       provided  that any  such new  Election  shall  be  effective  only if the
       conditions  in clauses (i) and (ii) of Section  IV(a) above are satisfied
       with  respect  to  such  new  Election.  Any  prior  Election  made  by a
       participant  that has satisfied  such  conditions  remains  effective for
       purposes  of this Plan until  such  participant  has made a new  Election
       satisfying such conditions.

(d)    A  participant  making an election  under this Section IV may specify the
       portion of his  benefits  under this Plan to be received in a lump sum as
       follows: 0 percent, 25 percent, 50 percent, 75 percent or 100 percent.

(e)    In the  event a  participant  who has made an  Election  dies or  becomes
       disabled  within the meaning of the Company's  long-term  disability plan
       while  employed  by  the  Company  or an  affiliate  and  such  death  or
       disability  occurs  during  the   12-calendar-month   period


<PAGE>



       immediately  following the Election Date of such Election,  the condition
       that such  participant  remain  employed with the Company or an affiliate
       for  such  12-month  period  shall be  deemed  to be  satisfied  and such
       Election  shall be  effective  with  respect to benefits  payable to such
       participant or participant's beneficiaries under this Plan.

(f)    The  amount of any  portion of the  benefits  payable as a lump sum under
       this  Section IV will  equal the  present  value of such  portion of such
       benefits,  and the  present  value  shall be  determined  (i)  based on a
       discount  rate equal to the  average of 85% of the  15-year  non-callable
       U.S.  Treasury  bond  yields  as of the  close  of  business  on the last
       business day of each of the three months  immediately  preceding the date
       the annuity  value is  determined  and (ii) using the 1983 Group  Annuity
       Mortality Table.

(g)    "Election  Date" for purposes of this Plan means the date that a properly
       completed  election  form with  respect to an Election is received by the
       Company.

                       Section V -- Cessation of Benefits

(a)    Notwithstanding any other provision of the Plan (except as provided below
       in this Section V), no benefits or no further  benefits,  as the case may
       be, shall be paid to a  participant  (or his or her  beneficiary)  if the
       participant has:

       (i)    become a  stockholder  (unless  such stock is listed on a national
              securities   exchange   or  traded   on  a  daily   basis  in  the
              over-the-counter  market and the participant's  ownership interest
              is not in excess of 2% of the  company  of which  the  shares  are
              being purchased),  employee, officer, director or consultant of or
              to a Company,  or a member or an employee of or a consultant  to a
              partnership or any other business or firm, which competes with any
              of the  businesses  owned or  operated by the  Company,  or if the
              participant  becomes  associated  with a company,  partnership  or
              individual  which  company,  partnership  or individual  acts as a
              consultant  to businesses in  competition  with the Company,  such
              participant  provided  services  to  such  competing   businesses,
              whether or not, in any of the foregoing  cases,  such  participant
              accepts any form of  compensation  from such  competing  entity or
              consultant; or

       (ii)   been  discharged from employment with the Company or any affiliate
              for  "cause."  "Cause"  means (1) willful  malfeasance  or willful
              misconduct  by  the  participant  in  connection  with  his or her
              employment,  (2) continuing  failure to perform such duties as are
              requested by any employee to whom the  participant  reports or the
              board of  directors  of the Company,  or (3) the  commission  by a
              participant  of (I) any felony or (II) any  misdemeanor  involving
              moral turpitude.

(b)    In any case described in this Section V, the  participant  (or his or her
       beneficiary)  shall be given prior written  notice that no benefits or no
       further  benefits,  as the case may be, will be paid to such  participant
       (or his or her  beneficiary).  Such  written  notice  shall  specify  the
       particular act(s), or failures to act, on the basis of which the decision
       to cease paying his or her benefits has been made.

(c)    Notwithstanding  any other  provision  of the  Plan,  a  participant  who
       receives in a lump sum any portion of his or her benefits hereunder shall
       receive such lump sum portion of such  benefits  subject to the condition
       that if such  participant  engages in any of the acts  described  in this
       Section  V, then such  participant  shall  within 60 days  after  written
       notice


<PAGE>



       by  the  Company  repay  to  the  Company  the  amount  described  in the
       immediately  succeeding  sentence.  The amount described in this sentence
       shall equal the amount of the  participant's  lump sum benefit under this
       Plan to which such participant would not have been entitled, if such lump
       sum benefit had instead been payable in the form of an annuity under this
       Plan and such annuity  payments  were subject to the  provisions  of this
       Section V.

(d)    Notwithstanding anything to the contrary contained herein, the provisions
       of this Section V shall be of no further force or effect from and after a
       "Change in Control"  with respect to  participants  then  employed by the
       Company or its Affiliates.  For this purpose, a "Change in Control" shall
       mean:

       (i)    any  "Person," as such term is used for purposes of Section  13(d)
              or 14(d)of the  Securities  Exchange Act of 1934,  as amended (the
              "Exchange  Act")  (other  than the  Company,  any trustee or other
              fiduciary holding securities under an employee benefit plan of the
              Company,  or any company  owned,  directly or  indirectly,  by the
              stockholders of the Company in substantially  the same proportions
              as  their  ownership  of  stock  of  the  Company),   becomes  the
              "Beneficial  Owner" (as defined in Rule 13d-3  under the  Exchange
              Act),  directly  or  indirectly,  of  securities  of  the  Company
              representing  20% or  more of the  combined  voting  power  of the
              Company's then-outstanding securities;

       (ii)   during any period of 24 months (not  including any period prior to
              the effective date of this Plan), individuals who at the beginning
              of such period  constitute  the board of  directors of the Company
              (the  "Board"),  and any new  director  (other than (a) a director
              nominated by a Person who has entered  into an agreement  with the
              Company to effect a transaction described in paragraphs (i), (iii)
              or (iv) of this  Section  V(d),  (b) a director  nominated  by any
              Person (including the Company) who publicly announces an intention
              to take or to consider taking actions (including,  but not limited
              to, an actual or threatened  proxy  contest)  which if consummated
              would  constitute a Change in Control or (c) a director  nominated
              by any Person who is the Beneficial Owner, directly or indirectly,
              of  securities  of the  Company  representing  10% or  more of the
              combined voting power of the Company's  securities) whose election
              by  the  Board  or  nomination   for  election  by  the  Company's
              stockholders  was  approved  in  advance  by a  vote  of at  least
              two-thirds of the  directors  then still in office who either were
              directors  at the  beginning  of the 


<PAGE>



              period or whose election or nomination for election was previously
              so  approved,  cease  for any  reason  to  constitute  at  least a
              majority thereof;

       (iii)  the  stockholders of the Company approve any transaction or series
              of transactions  under which the Company is merged or consolidated
              with any other company,  other than a merger or consolidation  (1)
              which  would  result  in the  voting  securities  of  the  Company
              outstanding  immediately  prior  thereto  continuing  to represent
              (either by remaining outstanding or by being converted into voting
              securities of the surviving entity) more than 66 % of the combined
              voting  powers of the  voting  securities  of the  Company or such
              surviving  entity  outstanding  immediately  after such  merger or
              consolidation  and (2) 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; or

       (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.


<PAGE>



                              Section VI -- Funding

Benefits  payable  under  this Plan shall not be funded and shall be made out of
the general funds of the Company;  provided,  however, that the Company reserves
the right to  establish  one or more  trusts to  provide  alternate  sources  of
benefit  payments under this Plan,  provided,  further,  however,  that upon the
occurrence of a "Potential Change in Control" of the Company,  as defined below,
the appropriate  officers of the Company are required to make  contributions  to
such a trust fund,  established as an alternate source of benefits payable under
the Plan,  as are  necessary to fund the lump sum payments to Plan  participants
required  pursuant to Section V of this Plan in the event of a Change in Control
of the Company; provided,  further, however, that if payments are made from such
trust fund, such payments will satisfy the Company's obligations under this Plan
to the extent made from such trust fund.

In determining the amount of the necessary contribution to the trust fund in the
event of a Potential  Change in Control,  the  following  actuarial  assumptions
shall be used: (i) the interest rate used shall be the interest rate used by the
Pension  Benefit  Guaranty  Corporation  for  determining the value of immediate
annuities  as of  January  1st of the year of the  occurrence  of the  Potential
Change in Control,  (ii) the 1983 Group Annuity  Mortality  Table shall be used;
and (iii) it shall be assumed  that all  participants  will retire or  terminate
employment  with the Company as soon as practicable  after the occurrence of the
Potential Change in Control.

For the purpose of this Plan, "Potential Change in Control" means:

(a)    the Company  enters into an  agreement,  the  consumption  of which would
       result in the occurrence of a Change in Control of the Company;

(b)    any person  (including the Company)  publicly  announces its intention to
       take or to consider taking actions which if consummated  would constitute
       a Change in Control of the Company;

(c)    any person,  other than a trustee or other fiduciary  holding  securities
       under an employee  benefit plan of the Company (or a  corporation  owned,
       directly  or  indirectly,   by  the   stockholders   of  the  Company  in
       substantially  the same  proportions  as their  ownership of stock of the
       Company), who is or becomes the beneficial owner, directly or indirectly,
       of  securities of the Company  representing  9.5% or more of the combined
       voting power of


<PAGE>



       the  Company's  then  outstanding   securities,   increases  his  or  her
       beneficial ownership of such securities by 5% or more over the percentage
       so owned by such person; or

(d)    The Board of Directors of the Company  adopts a resolution  to the effect
       that,  for  purposes of this Plan,  a Potential  Change in Control of the
       Company has occurred.


<PAGE>



                          Section VII -- Miscellaneous

(a)    The Compensation and Benefits  Committee of the board of directors of the
       Company shall be responsible for the  administration  of the Plan and may
       delegate to any  management  committee,  employee,  director or agent its
       responsibility to perform any act hereunder, including without limitation
       those matters  involving the exercise of  discretion,  provided that such
       delegation  shall be subject to revocation at any time at the Committee's
       discretion.  The  Committee  shall have the  authority to  determine  all
       questions   arising  in  connection  with  the  Plan,  to  interpret  the
       provisions  of the Plan and construe all of its terms,  to adopt,  amend,
       and rescind rules and regulations for the administration of the Plan, and
       generally   to  conduct  and   administer   the  Plan  and  to  make  all
       determinations  in  connection  with  the  Plan  as may be  necessary  or
       advisable.  All such actions of the  Committee  shall be  conclusive  and
       binding upon all participants and beneficiaries.

(b)    The Committee may, in its sole  discretion,  terminate,  suspend or amend
       this  Plan at any  time or  from  time to  time,  in  whole  or in  part;
       provided,  however,  that in the  event of  termination,  the  rights  of
       participants   to  their   accrued   benefits   hereunder   shall  become
       nonforfeitable.  No termination,  suspension or amendment of the Plan may
       adversely affect a participant's or beneficiary's  benefit to which he or
       she is  entitled  under  the Plan as in  effect  on the date  immediately
       preceding the date of such termination, suspension or amendment.

(c)    Nothing contained herein will confer upon any participant the right to be
       retained  in the  service of the  Company or any  affiliate,  nor will it
       interfere  with the right of the Company or any affiliate to discharge or
       otherwise deal with participants with respect to matters of employment.

(d)    A  participant's  right to benefit  payments  under the Plan shall not be
       subject  in any  manner  to  anticipation,  alienation,  sale,  transfer,
       assignment,  pledge, encumbrance,  attachment or garnishment by creditors
       of such participant or his or her beneficiary.

(e)    The  Company  may  withhold  from any  benefit  under  the Plan an amount
       sufficient to satisfy its tax withholding obligations.


<PAGE>

                                   APPENDIX A

The benefits payable from the Retirement  Benefit and  Equalization  Plan of The
Dun & Bradstreet  Corporation  (the "Excess Plan") to  participants of this Plan
shall be  determined  as amounts  payable  monthly in the form of a single  life
annuity  commencing  on the  first  day of the  month  coincident  with  or next
following  the date  the  participant  attains  age 65 (the  "Normal  Retirement
Date").

In the event a participant's benefit from this Plan is paid in a form other than
a single life  annuity,  however,  the  benefits  payable from the PBEP shall be
adjusted to equal the  actuarial  equivalent  value of the single  life  annuity
amount computed on the basis of mortality rates shown in Appendix B of this Plan
and  6.75%  interest.  In the  event a  participant's  benefit  from  this  Plan
commences prior to the participant's Normal Retirement Date, and the participant
terminated  employment  with the Company on or after he or she  attained age 55,
the  benefits  payable  from the PBEP  commencing  on the first day of the month
coincident with or next following the participant's Normal Retirement Date shall
be reduced by 3/12% for each month prior to the Normal  Retirement  Date (or age
60 if the  participant  has 35 years of service  on his or her Early  Retirement
Date) that benefits  commence.  In the event a  participant's  benefit from this
Plan  commences  prior to the  participant's  Normal  Retirement  Date,  and the
participant terminated employment with the Company before he or she attained age
55, the benefits  payable from the PBEP as  determined  in  accordance  with the
provisions  set forth above shall be adjusted to equal the actuarial  equivalent
value of such amount  computed on the basis of mortality rates shown in Appendix
B of this Plan and 6.75% interest.

                                RIGHTS AGREEMENT

     Agreement,  dated as of June 15, 1998  between IMS Health  Incorporated,  a
Delaware  corporation  (the  "Company"),  and First Chicago Trust Company of New
York (the "Rights Agent").

     The Board of  Directors  of the  Company  has  authorized  and  declared  a
dividend of one  preferred  share  purchase  right (a "Right") for each share of
Common Stock (as hereinafter defined) of the Company outstanding as of the close
of business (as defined  below) on June 29, 1998 (the "Record  Date") each Right
representing the right to purchase  one-thousandth  (subject to adjustment) of a
share of Preferred Stock (as hereinafter defined), upon the terms and subject to
the  conditions  herein  set  forth,  and the  Board of  Directors  has  further
authorized  and  directed the issuance of one Right  (subject to  adjustment  as
provided  herein)  with  respect to each share of Common Stock that shall become
outstanding  between the Record Date and the earliest of the Distribution  Date,
the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined); provided, however, that Rights may be issued with respect to shares of
Common Stock that shall become outstanding after the Distribution Date and prior
to the Redemption Date and the Final  Expiration Date in accordance with Section
22.

                                                                               2


     Accordingly,  in  consideration  of the premises and the mutual  agreements
herein set forth, the parties hereby agree as follows:

     Section Certain Definitions.  For purposes of this Agreement, the following
terms have the meaning indicated:

          "Acquiring  Person" shall mean any Person (as such term is hereinafter
     defined)  who or  which  shall be the  Beneficial  Owner  (as such  term is
     hereinafter  defined)  of 15% or more of the  shares of Common  Stock  then
     outstanding (or, if an Institutional  Investor (as hereinafter defined) 20%
     or more of the  shares of Common  Stock  then  outstanding),  but shall not
     include an Exempt Person (as such term is hereinafter  defined);  provided,
     however,  that if the Board of Directors of the Company  determines in good
     faith that a Person who would otherwise be an "Acquiring Person" has become
     such inadvertently (including,  without limitation, because (i) such Person
     was unaware that it  beneficially  owned a percentage  of Common Stock that
     would otherwise cause such Person to be an "Acquiring  Person" or (ii) such
     Person was aware of the extent of its Beneficial  Ownership of Common Stock
     but  had  no  actual  knowledge  of the  consequences  of  such  Beneficial
     Ownership  under this  Rights  Agreement)  and  without  any  intention  of
     changing  or  influencing  control  of the  Company,  and such  Person,  as
     promptly as practicable after being advised of such determination  divested
     or 

<PAGE>
                                                                               3



     divests himself or itself of Beneficial Ownership of a sufficient number of
     shares of Common  Stock so that such Person would no longer be an Acquiring
     Person,  then such  Person  shall not be deemed to be or to have  become an
     "Acquiring Person" for any purposes of this Agreement.  Notwithstanding the
     foregoing,  (i) the  sole  stockholder  of the  Company  at the time of the
     adoption of this Agreement  will not be deemed an Acquiring  Person for any
     purposes of this Agreement prior to the  distribution by such Person of the
     Company's  outstanding  Common Stock to the stockholders of such Person and
     (ii) no Person  shall  become an  "Acquiring  Person"  as the  result of an
     acquisition of shares of Common Stock by the Company which, by reducing the
     number of shares outstanding,  increases the proportionate number of shares
     beneficially  owned by such  Person to 15% or more (20% or more in the case
     of  an  Institutional   Investor)  of  the  shares  of  Common  Stock  then
     outstanding,   provided,  however,  that  if  a  Person  shall  become  the
     Beneficial  Owner  of  15%  or  more  (20%  or  more  in  the  case  of  an
     Institutional  Investor) of the shares of Common Stock then  outstanding by
     reason of such share acquisitions by the Company and thereafter becomes the
     Beneficial  Owner of any  additional  shares of Common  Stock  (other  than
     pursuant to a dividend or  distribution  paid or made by the Company on the
     outstanding  Common  Stock in shares of Common Stock or pursuant to a split
     or subdivision of 

<PAGE>
                                                                               4



     the  outstanding  Common Stock),  then such Person shall be deemed to be an
     "Acquiring  Person" unless upon the consummation of the acquisition of such
     additional shares of Common Stock such Person does not own 15% or more (20%
     or more in the case of an  Institutional  Investor) of the shares of Common
     Stock then outstanding. For all purposes of this Agreement, any calculation
     of the number of shares of Common Stock outstanding at any particular time,
     including for purposes of  determining  the  particular  percentage of such
     outstanding  shares of Common  Stock of which any Person is the  Beneficial
     Owner,  shall  be  made  in  accordance  with  the  last  sentence  of Rule
     13d-3(d)(1)(i)  of the General Rules and  Regulations  under the Securities
     Exchange Act of 1934, as amended (the "Exchange  Act"), as in effect on the
     date hereof.

          "Affiliate"  and  "Associate"  shall  have  the  respective   meanings
     ascribed to such terms in Rule 12b-2 of the General  Rules and  Regulations
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
     as in effect on the date of this Agreement.

          A Person shall be deemed the "Beneficial Owner" of, shall be deemed to
     have "Beneficial  Ownership" of and shall be deemed to  "beneficially  own"
     any securities:

               which  such  Person  or  any  of  such  Person's   Affiliates  or
          Associates  is deemed to

          beneficially  own,  directly or indirectly  within the meaning of Rule
          13d-3 of the General Rules and  Regulations  under the Exchange Act as
          in effect on the date of this Agreement;

               which  such  Person  or  any  of  such  Person's   Affiliates  or
          Associates  has (A) the  right  to  acquire  (whether  such  right  is
          exercisable immediately or only after the passage of time) pursuant to
          any  agreement,  arrangement  or  understanding  (other than customary
          agreements  with and between  underwriters  and selling  group members
          with respect to a bona fide public  offering of  securities),  or upon
          the exercise of conversion rights,  exchange rights, rights,  warrants
          or options, or otherwise;  provided,  however, that a Person shall not
          be  deemed  the  Beneficial  Owner  of, or to  beneficially  own,  (x)
          securities  tendered pursuant to a tender or exchange offer made by or
          on  behalf  of such  Person  or any of  such  Person's  Affiliates  or
          Associates  until such tendered  securities are accepted for purchase,
          (y)  securities  which  such  Person  has a right  to  acquire  on the
          exercise  of Rights at any time prior to the time a Person  becomes an
          Acquiring  Person or (z)  securities  issuable upon exercise of Rights
          from and after the time a Person  becomes an Acquiring  Person if such
          Rights were acquired by such Person or any of such

          any agreement, arrangement or understanding; provided, however, that a
          Person shall not be deemed the Beneficial Owner of, or to beneficially
          own,  any  security  by  reason  of  such  agreement,  arrangement  or
          understanding  if the agreement,  arrangement or understanding to vote
          such  security  (1) arises  solely from a  revocable  proxy or consent
          given  to such  Person  in  response  to a  public  proxy  or  consent
          solicitation  made pursuant to, and in accordance with, the applicable

          any comparable or successor report); or

               which are  beneficially  owned,  directly or  indirectly,  by any
          other Person with which such Person or any of such Person's Affiliates
          or Associates has any agreement,  arrangement or understanding  (other
          than customary  agreements with and between  underwriters  and selling
          group  members  with  respect  to  a  bona  fide  public  offering  of

of this Agreement and prior to the issuance of the Rights),  the earlier of such
dates being herein referred to as the "Distribution  Date"), (x) the Rights will
be  evidenced  (subject  to  the  provisions  of  Section  3(b)  hereof)  by the
certificates for Common Stock registered in the names of the holders thereof and
not by separate Right Certificates, and (y) the Rights will be transferable only

to each  record  holder  of  Common  Stock as of the  close of  business  on the
Distribution Date (other than any Acquiring Person or any Associate or Affiliate

                                                                              12



the Record Date (other than any  Acquiring  Person or any Associate or Affiliate
of any Acquiring Person),  at the address of such holder shown on the records of
the Company. With respect to certificates for Common Stock outstanding as of the
Record Date, until the  Distribution  Date, the Rights will be evidenced by such
certificates  registered in the names of the holders  thereof  together with the
Summary of Rights. Until the Distribution Date (or the earlier of the Redemption
Date  or  the  Final  Expiration  Date),  the  surrender  for  transfer  of  any
certificate  for Common Stock  outstanding on the Record Date, with or without a
copy of the Summary of Rights,  shall also constitute the transfer of the Rights
associated with the Common Stock represented thereby.

     Certificates issued for Common Stock (including,  without limitation,  upon
transfer  of  outstanding  Common  Stock,  disposition  of  Common  Stock out of
treasury  stock or issuance or reissuance of Common Stock out of authorized  but
unissued  shares)  after  the  Record  Date  but  prior to the  earliest  of the
Distribution  Date, the Redemption Date or the Final  Expiration Date shall have
impressed on, printed on, written on or otherwise  affixed to them the following
legend:

          This  certificate  also  evidences  and entitles the holder  hereof to
     certain  rights  as set  forth in a Rights  Agreement  between  IMS  Health
     Incorporated  and First Chicago Trust Company of New York, dated as of June
     15,  1998 as the  same  may be  amended  from  time to  time  (the  "Rights
     Agreement"), the terms of which are hereby incorporated herein by reference
     and a copy of which is on file at the  principal  executive  offices of IMS

<PAGE>
                                                                              13



     Health  Incorporated.  Under  certain  circumstances,  as set  forth in the
     Rights  Agreement,  such Rights will be evidenced by separate  certificates
     and  will  no  longer  be  evidenced  by  this   certificate.   IMS  Health
     Incorporated  will  mail to the  holder of this  certificate  a copy of the
     Rights  Agreement  without  charge  after  receipt  of  a  written  request
     therefor.  Under  certain  circumstances,   as  set  forth  in  the  Rights
     Agreement,  Rights  owned by or  transferred  to any Person who  becomes an
     Acquiring  Person  (as  defined  in  the  Rights   Agreement)  and  certain
     transferees  thereof  will  become  null and void  and  will no  longer  be
     transferable.

With respect to such  certificates  containing the foregoing  legend,  until the
Distribution  Date, the Rights  associated with the Common Stock  represented by
such  certificates  shall  be  evidenced  by such  certificates  alone,  and the
surrender  for transfer of any such  certificate,  except as otherwise  provided
herein,  shall also  constitute the transfer of the Rights  associated  with the
Common Stock  represented  thereby.  In the event that the Company  purchases or
otherwise  acquires  any Common  Stock  after the  Record  Date but prior to the
Distribution  Date, any Rights associated with such Common Stock shall be deemed
cancelled  and retired so that the Company shall not be entitled to exercise any
Rights associated with the Common Stock which are no longer outstanding.

     Notwithstanding  this  paragraph  (c),  the  omission of a legend shall not
affect the  enforceability  of any part of this  Agreement  or the rights of any
holder of the Rights.

     Section Form of Right  Certificates.  The Right Certificates (and the forms
of election to purchase  shares 

<PAGE>
                                                                              14



and of assignment to be printed on the reverse  thereof) shall be  substantially
in the  form  set  forth  in  Exhibit  B  hereto  and may  have  such  marks  of
identification  or  designation  and such  legends,  summaries  or  endorsements
printed thereon as the Company may deem  appropriate and as are not inconsistent
with the provisions of this Agreement,  or as may be required to comply with any
applicable law or with any rule or regulation made pursuant  thereto or with any
rule or regulation of the New York Stock Exchange or of any other stock exchange
or  automated  quotation  system  on which the  Rights  may from time to time be
listed, or to conform to usage. Subject to the provisions of Sections 11, 13 and
22 hereof,  the Right Certificates shall entitle the holders thereof to purchase
such number of one one-thousandths of a share of Preferred Stock as shall be set
forth therein at the price per one  one-thousandth of a share of Preferred Stock
set  forth  therein  (the  "Purchase  Price"),   but  the  number  of  such  one
one-thousandths  of a share of Preferred  Stock and the Purchase  Price shall be
subject to adjustment as provided herein.

     Section Countersignature and Registration.  The Right Certificates shall be
executed on behalf of the Company by the Chairman of the Board of Directors, the
President,  any of the Vice  Presidents,  the Treasurer or the Controller of the
Company,  either manually or by facsimile signature,  shall have affixed thereto
the  Company's  seal or a  facsimile  thereof,  and  shall  be  attested  by the
Secretary  or an  Assistant  Secretary  of the  Company,  either  manually or 

<PAGE>
                                                                              15



by facsimile signature.  The Right Certificates shall be manually  countersigned
by the Rights Agent and shall not be valid for any purpose unless countersigned.
In case any  officer  of the  Company  who shall  have  signed  any of the Right
Certificates   shall   cease  to  be  such   officer  of  the   Company   before
countersignature  by the Rights  Agent and issuance and delivery by the Company,
such Right Certificates,  nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the Person who signed such Right  Certificates had not ceased to be such officer
of the Company; and any Right Certificate may be signed on behalf of the Company
by  any  Person  who,  at the  actual  date  of  the  execution  of  such  Right
Certificate,  shall  be a proper  officer  of the  Company  to sign  such  Right
Certificate,  although at the date of the  execution of this  Agreement any such
Person was not such an officer.

     Following the Distribution  Date, the Rights Agent will keep or cause to be
kept, at an office or agency designated for such purpose, books for registration
and transfer of the Right Certificates  issued hereunder.  Such books shall show
the names and addresses of the respective holders of the Right Certificates, the
number of Rights evidenced on its face by each of the Right Certificates and the
date of each of the Right Certificates.

     Section Transfer, Split Up, Combination and Exchange of Right Certificates;
Mutilated,  Destroyed,  Lost  or  Stolen  Right  Certificates.  Subject  to  the
provisions  

<PAGE>
                                       16



of  Sections  7(e),  11(a)(ii)  and 14  hereof,  at any time  after the close of
business  on the  Distribution  Date,  and prior to the close of business on the
earlier  of the  Redemption  Date  or  the  Final  Expiration  Date,  any  Right
Certificate or Right  Certificates  may be  transferred,  split up,  combined or
exchanged for another Right  Certificate  or Right  Certificates,  entitling the
registered holder to purchase a like number of one one-thousandths of a share of
Preferred Stock as the Right Certificate or Right Certificates  surrendered then
entitled such holder to purchase.  Any registered  holder  desiring to transfer,
split up, combine or exchange any Right Certificate or Right  Certificates shall
make such request in writing  delivered to the Rights Agent, and shall surrender
the  Right  Certificate  or Right  Certificates  to be  transferred,  split  up,
combined or exchanged at the office or agency of the Rights Agent designated for
such purpose.  Thereupon the Rights Agent shall  countersign  and deliver to the
Person entitled thereto a Right Certificate or Right  Certificates,  as the case
may be, as so requested.  The Company may require payment of a sum sufficient to
cover any tax or governmental  charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

     Subject to the provisions of Section  11(a)(ii)  hereof,  at any time after
the  Distribution  Date and prior to the close of business on the earlier of the
Redemption  Date or the Final  Expiration  Date, upon receipt by the Company and
the Rights Agent of evidence reasonably 

<PAGE>
                                                                              17



satisfactory  to them of the loss,  theft,  destruction or mutilation of a Right
Certificate,  and,  in case of  loss,  theft or  destruction,  of  indemnity  or
security  reasonably  satisfactory  to  them,  and,  at the  Company's  request,
reimbursement  to the Company and the Rights  Agent of all  reasonable  expenses
incidental  thereto,  and upon surrender to the Rights Agent and cancellation of
the Right  Certificate  if  mutilated,  the Company  will make and deliver a new
Right  Certificate  of like  tenor  to the  Rights  Agent  for  delivery  to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

     Section  Exercise of Rights,  Purchase  Price;  Expiration  Date of Rights.
Except as otherwise  provided herein, the Rights shall become exercisable on the
Distribution Date, and thereafter the registered holder of any Right Certificate
may,  subject to Section  11(a)(ii)  hereof  and  except as  otherwise  provided
herein, exercise the Rights evidenced thereby in whole or in part upon surrender
of the Right  Certificate,  with the form of election to purchase on the reverse
side thereof duly  executed,  to the Rights Agent at the office or agency of the
Rights Agent designated for such purpose,  together with payment of the Purchase
Price for each one  one-thousandth of a share of Preferred Stock as to which the
Rights are exercised,  at any time which is both after the Distribution Date and
prior to the  earliest of (i) the close of business on June 30, 2008 (the "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 hereof (the 

<PAGE>
                                                                              18



"Redemption  Date") or (iii) the time at which  such  Rights  are  exchanged  as
provided in Section 24 hereof.

     The Purchase Price shall be initially $225 for each one one-thousandth of a
share of Preferred Stock  purchasable upon the exercise of a Right. The Purchase
Price and the number of one  one-thousandths  of a share of  Preferred  Stock or
other  securities  or property to be acquired  upon exercise of a Right shall be
subject to adjustment from time to time as provided in Sections 11 and 13 hereof
and shall be  payable  in  lawful  money of the  United  States  of  America  in
accordance with paragraph (c) of this Section 7.

     Except as otherwise  provided herein,  upon receipt of a Right  Certificate
representing  exercisable  Rights,  with the form of election  to purchase  duly
executed,  accompanied by payment of the aggregate Purchase Price for the shares
of  Preferred  Stock to be  purchased  and an  amount  equal  to any  applicable
transfer  tax  required  to be paid by the holder of such Right  Certificate  in
accordance with Section 9 hereof, in cash or by certified check, cashier's check
or money  order  payable to the order of the  Company,  the Rights  Agent  shall
thereupon  promptly (i) (A) requisition from any transfer agent of the Preferred
Stock  certificates  for the number of shares of Preferred Stock to be purchased
and the Company hereby irrevocably  authorizes its transfer agent to comply with
all such  requests,  or (B)  requisition  from the depositary  agent  depositary
receipts representing interests in such number of one one-thousandths 

<PAGE>
                                                                              19



of a share of Preferred Stock as are to be purchased (in which case certificates
for the Preferred  Stock  represented by such receipts shall be deposited by the
transfer  agent with the  depositary  agent) and the Company  hereby directs the
depositary agent to comply with such request, (ii) when appropriate, requisition
from the Company the amount of cash to be paid in lieu of issuance of fractional
shares in accordance  with Section 14 hereof,  (iii)  promptly  after receipt of
such certificates or depositary  receipts,  cause the same to be delivered to or
upon the order of the registered holder of such Right Certificate, registered in
such  name  or  names  as may  be  designated  by  such  holder  and  (iv)  when
appropriate,  after receipt,  promptly deliver such cash to or upon the order of
the registered holder of such Right Certificate.

     Except as otherwise  provided herein,  in case the registered holder of any
Right Certificate shall exercise less than all the Rights evidenced  thereby,  a
new Right Certificate  evidencing  Rights  equivalent to the exercisable  Rights
remaining  unexercised  shall be issued by the  Rights  Agent to the  registered
holder of such Right Certificate or to his duly authorized  assigns,  subject to
the provisions of Section 14 hereof.

     Notwithstanding  anything in this  Agreement to the  contrary,  neither the
Rights Agent nor the Company  shall be  obligated  to undertake  any action with
respect to a registered  holder of Rights upon the  occurrence  of any purported
transfer or exercise  of Rights  pursuant to Section 

<PAGE>
                                                                              20



6 hereof  or this  Section  7  unless  such  registered  holder  shall  have (i)
completed  and signed the  certificate  contained in the form of  assignment  or
election to purchase  set forth on the  reverse  side of the Rights  Certificate
surrendered  for such  transfer or exercise and (ii)  provided  such  additional
evidence of the identity of the Beneficial  Owner (or former  Beneficial  Owner)
thereof as the Company shall reasonably request.

     Section  Cancellation  and  Destruction  of Right  Certificates.  All Right
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered  to the Rights Agent,  shall be cancelled by it, and no Right
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement,  and the Rights Agent shall so cancel and
retire,  any other  Right  Certificate  purchased  or  acquired  by the  Company
otherwise  than upon the exercise  thereof.  The Rights Agent shall  deliver all
cancelled Right Certificates to the Company, or shall, at the written request of
the Company,  destroy such cancelled Right Certificates,  and in such case shall
deliver a certificate of destruction thereof to the Company.

     Section  Availability of Shares of Preferred Stock.  The Company  covenants
and  agrees  that it 

<PAGE>
                                                                              21



will cause to be reserved and kept  available out of its authorized and unissued
shares of Preferred Stock or any shares of Preferred Stock held in its treasury,
the number of shares of Preferred  Stock that will be  sufficient  to permit the
exercise in full of all outstanding Rights.

     So long as the shares of Preferred  Stock (and,  following  the time that a
Person becomes an Acquiring Person, shares of Common Stock and other securities)
issuable upon the exercise of Rights may be listed or admitted to trading on the
New York Stock Exchange or listed on any other national  securities  exchange or
quotation  system,  the Company  shall use its best  efforts to cause,  from and
after such time as the Rights become  exercisable,  all shares reserved for such
issuance to be listed or  admitted to trading on the New York Stock  Exchange or
listed on any  other  exchange  or  quotation  system  upon  official  notice of
issuance upon such exercise.

     From and after  such time as the Rights  become  exercisable,  the  Company
shall use its best efforts,  if then  necessary to permit the issuance of shares
of  Preferred  Stock  (and  following  the time that a Person  first  becomes an
Acquiring Person, shares of Common Stock and other securities) upon the exercise
of Rights, to register and qualify such shares of Preferred Stock (and following
the time that a Person first becomes an Acquiring Person, shares of Common Stock
and  other  securities)  under  the  Securities  Act  and any  applicable  state
securities  or "Blue  Sky"  laws (to the  extent  exemptions  therefrom  are not
available),  

<PAGE>
                                                                              22



cause such registration statement and qualifications to become effective as soon
as possible  after such  filing and keep such  registration  and  qualifications
effective  until the  earlier  of the date as of which the  Rights are no longer
exercisable for such securities and the Final  Expiration  Date. The Company may
temporarily  suspend,  for  a  period  of  time  not  to  exceed  90  days,  the
exercisability  of the  Rights  in order  to  prepare  and  file a  registration
statement under the Securities Act and permit it to become  effective.  Upon any
such suspension,  the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement   at  such  time  as  the   suspension  is  no  longer  in  effect.
Notwithstanding  any  provision of this  Agreement to the  contrary,  the Rights
shall not be exercisable in any jurisdiction unless the requisite  qualification
in such jurisdiction shall have been obtained and until a registration statement
under the Securities Act (if required) shall have been declared effective.

     The Company  covenants  and agrees that it will take all such action as may
be necessary to ensure that all shares of Preferred  Stock (and,  following  the
time that a Person becomes an Acquiring Person, shares of Common Stock and other
securities)  delivered upon exercise of Rights shall, at the time of delivery of
the certificates  therefor  (subject to payment of the Purchase Price),  be duly
and validly authorized and issued and fully paid and nonassessable shares.

                                                                              23



     The  Company  further  covenants  and agrees  that it will pay when due and
payable any and all federal and state  transfer  taxes and charges  which may be
payable in respect of the issuance or delivery of the Right  Certificates  or of
any shares of Preferred  Stock (or shares of Common  Stock or other  securities)
upon the exercise of Rights. The Company shall not, however,  be required to pay
any  transfer tax which may be payable in respect of any transfer or delivery of
Right  Certificates  to a Person  other  than,  or the  issuance  or delivery of
certificates or depositary receipts for the Preferred Stock (or shares of Common
Stock or other  securities) in a name other than that of, the registered  holder
of the Right Certificate  evidencing Rights surrendered for exercise or to issue
or deliver any  certificates  or  depositary  receipts for  Preferred  Stock (or
shares of Common  Stock or other  securities)  upon the  exercise  of any Rights
until any such tax shall  have  been  paid (any such tax being  payable  by that
holder of such Right  Certificate at the time of surrender) or until it has been
established to the Company's reasonable satisfaction that no such tax is due.

     Section  Preferred  Stock  Record  Date.  Each  Person  in  whose  name any
certificate  for Preferred Stock is issued upon the exercise of Rights shall for
all  purposes  be deemed to have  become  the  holder of record of the shares of
Preferred Stock represented thereby on, and such certificate shall be dated, the
date  upon  which  the  Right  Certificate   evidencing  such  Rights  was  duly
surrendered  and  payment of 

<PAGE>
                                                                              24



the  Purchase  Price (and any  applicable  transfer  taxes) was made;  provided,
however, that if the date of such surrender and payment is a date upon which the
Preferred  Stock transfer books of the Company are closed,  such Person shall be
deemed to have become the record holder of such shares on, and such  certificate
shall be dated,  the next  succeeding  Business Day on which the Preferred Stock
transfer  books of the  Company  are open.  Prior to the  exercise of the Rights
evidenced  thereby,  the holder of a Right  Certificate shall not be entitled to
any  rights  of a holder of  Preferred  Stock  for  which  the  Rights  shall be
exercisable,  including,  without  limitation,  the right to vote or to  receive
dividends  or other  distributions,  and shall not be  entitled  to receive  any
notice of any proceedings of the Company, except as provided herein.

     Section  Adjustment  of  Purchase  Price,  Number of Shares  and  Number of
Rights.  The Purchase  Price,  the number of shares of Preferred  Stock or other
securities or property purchasable upon exercise of each Right and the number of
Rights  outstanding  are subject to adjustment  from time to time as provided in
this Section 11.

          In the  event  the  Company  shall at any time  after the date of this
     Agreement (A) declare a dividend on the  Preferred  Stock payable in shares
     of Preferred  Stock,  (B) subdivide the outstanding  Preferred  Stock,  (C)
     combine the outstanding  Preferred Stock into a smaller number of Preferred
     Stock or (D) issue any shares of its capital stock 

<PAGE>
                                                                              25



     in  a   reclassification   of  the  Preferred  Stock  (including  any  such
     reclassification  in connection with a consolidation or merger in which the
     Company is the  continuing or surviving  corporation),  except as otherwise
     provided in this Section 11(a), the Purchase Price in effect at the time of
     the  record  date  for  such  dividend  or of the  effective  date  of such
     subdivision,  combination or  reclassification,  and the number and kind of
     shares of capital  stock  issuable on such date,  shall be  proportionately
     adjusted so that the holder of any Right exercised after such time shall be
     entitled  to  receive  the  aggregate  number and kind of shares of capital
     stock which,  if such Right had been  exercised  immediately  prior to such
     date and at a time when the Preferred  Stock  transfer books of the Company
     were open, the holder would have owned upon such exercise and been entitled
     to  receive  by  virtue  of  such  dividend,  subdivision,  combination  or
     reclassification;   provided,   however,   that  in  no  event   shall  the
     consideration  to be paid upon the  exercise  of one Right be less than the
     aggregate par value of the shares of capital stock of the Company  issuable
     upon exercise of one Right.

          Subject to Section 24 of this Agreement,  in the event that any Person
     becomes an Acquiring Person,  then (A) the Purchase Price 

<PAGE>
                                                                              26



     shall be adjusted to be the Purchase Price in effect  immediately  prior to
     such Person  becoming an Acquiring  Person  multiplied by the number of one
     one-thousandths  of a share  of  Preferred  Stock  for  which  a Right  was
     exercisable  immediately prior to such Person becoming an Acquiring Person,
     whether or not such Right was then  exercisable,  and (B) each  holder of a
     Right,   except  as  otherwise  provided  in  this  Section  11(a)(ii)  and
     Subsection 11(a)(iii),  hereof, shall thereafter have the right to receive,
     upon exercise at a price equal to the Purchase  Price (as so adjusted),  in
     accordance  with  the  terms of this  Agreement  and in lieu of  shares  of
     Preferred Stock, such number of shares of Common Stock (or at the option of
     the  Company,  such number of one  one-thousandths  of shares of  Preferred
     Stock) as shall  equal the  result  obtained  by (x)  multiplying  the then
     current Purchase Price by the number of one  one-thousandths  of a share of
     Preferred  Stock for which a Right is then  exercisable  and dividing  that
     product  by (y) 50% of the  then  current  per  share  market  price of the
     Company's Common Stock (determined pursuant to Section 11(d) hereof) on the
     date such Person became an Acquiring Person;  provided,  however,  that the
     Purchase Price and the number of shares of Common Stock so receivable  upon
     exercise of a Right shall  thereafter  be

<PAGE>
                                                                              27



     subject to further  adjustment as  appropriate  in accordance  with Section
     11(f) hereof.  Notwithstanding  anything in this Agreement to the contrary,
     however,  from and after the time (the "invalidation time") when any Person
     first becomes an Acquiring Person,  any Rights that are beneficially  owned
     by (x) any Acquiring Person (or any Affiliate or Associate of any Acquiring
     Person), (y) a transferee of any Acquiring Person (or any such Affiliate or
     Associate) who becomes a transferee  after the  invalidation  time or (z) a
     transferee of any Acquiring Person (or any such Affiliate or Associate) who
     became a transferee  prior to or concurrently  with the  invalidation  time
     pursuant to either (I) a transfer from the  Acquiring  Person to holders of
     its  equity  securities  or to any Person  with whom it has any  continuing
     agreement, arrangement or understanding regarding the transferred Rights or
     (II) a transfer  which the Board of Directors  has  determined is part of a
     plan,  arrangement  or  understanding  which has the  purpose  or effect of
     avoiding the provisions of this  paragraph,  and subsequent  transferees of
     such  Persons,  shall be void without any further  action and any holder of
     such Rights shall thereafter have no rights whatsoever with respect to such
     Rights under any  provision of this  Agreement.  The Company  shall 

<PAGE>
                                                                              28



     use all  reasonable  efforts to ensure that the  provisions of this Section
     11(a)(ii) are complied  with,  but shall have no liability to any holder of
     Right  Certificates  or other Person as a result of its failure to make any
     determinations  with  respect  to an  Acquiring  Person or its  Affiliates,
     Associates or transferees hereunder.  From and after the invalidation time,
     no Right  Certificate  shall be issued  pursuant  to Section 3 or Section 6
     hereof that represents  Rights that are or have become void pursuant to the
     provisions of this paragraph,  and any Right  Certificate  delivered to the
     Rights Agent that  represents  Rights that are or have become void pursuant
     to the provisions of this paragraph shall be cancelled.  From and after the
     occurrence of an event  specified in Section 13(a) hereof,  any Rights that
     theretofore  have not been  exercised  pursuant to this  Section  11(a)(ii)
     shall  thereafter be exercisable only in accordance with Section 13 and not
     pursuant to this Section 11(a)(ii).

          (iii) The Company may at its option  substitute  for a share of Common
     Stock issuable upon the exercise of Rights in accordance with the foregoing
     subparagraph  (ii) such number or fractions  of shares of  Preferred  Stock
     having an  aggregate  current  market  value equal to the current per share
     market price of a share of 

<PAGE>
                                                                              29



     Common  Stock.  In the event that there shall not be  sufficient  shares of
     Common  Stock  issued but not  outstanding  or  authorized  but unissued to
     permit the exercise in full of the Rights in accordance  with the foregoing
     subparagraph (ii), the Board of Directors shall, to the extent permitted by
     applicable  law and any  material  agreements  then in  effect to which the
     Company is a party (A)  determine the excess of (1) the value of the shares
     of Common Stock  issuable upon the exercise of a Right in  accordance  with
     the foregoing  subparagraph  (ii) (the  "Current  Value") over (2) the then
     current Purchase Price multiplied by the number of one  one-thousandths  of
     shares of  Preferred  Stock for which a Right was  exercisable  immediately
     prior to the time that the Acquiring  Person became such (such excess,  the
     "Spread"), and (B) with respect to each Right (other than Rights which have
     become void  pursuant to Section  11(a)(ii)),  make  adequate  provision to
     substitute  for the shares of Common  Stock  issuable  in  accordance  with
     subparagraph  (ii) upon exercise of the Right and payment of the applicable
     Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) shares
     of Preferred  Stock or other equity  securities of the Company  (including,
     without limitation, shares or fractions of shares of preferred stock which,
     by virtue of having

                                                                              30



     dividend,  voting and liquidation rights substantially  comparable to those
     of the  shares of Common  Stock,  are  deemed in good faith by the Board of
     Directors  to have  substantially  the same  value as the  shares of Common
     Stock (such shares of preferred  stock and shares or fractions of shares of
     preferred stock are hereinafter referred to as "Common Stock equivalents"),
     (4)  debt  securities  of  the  Company,  (5)  other  assets,  or  (6)  any
     combination of the foregoing, having a value which, when added to the value
     of the shares of Common Stock actually  issued upon exercise of such Right,
     shall have an aggregate  value equal to the Current  Value (less the amount
     of any reduction in the Purchase  Price),  where such  aggregate  value has
     been  determined by the Board of Directors  upon the advice of a nationally
     recognized  investment  banking firm selected in good faith by the Board of
     Directors;  provided,  however,  if the  Company  shall  not make  adequate
     provision to deliver value  pursuant to clause (B) above within thirty (30)
     days following the date that the Acquiring Person became such (the "Section
     11(a)(ii)  Trigger Date"),  then the Company shall be obligated to deliver,
     to the extent permitted by applicable law and any material  agreements then
     in effect to which the Company is a party,  upon the surrender for

<PAGE>
                                                                              31



     exercise of a Right and without  requiring  payment of the Purchase  Price,
     shares of Common Stock (to the extent  available),  and then, if necessary,
     such  number  or  fractions  of shares of  Preferred  Stock (to the  extent
     available) and then, if necessary,  cash,  which shares and/or cash have an
     aggregate  value equal to the Spread.  If, upon the date any Person becomes
     an Acquiring  Person,  the Board of Directors shall determine in good faith
     that it is likely that sufficient  additional  shares of Common Stock could
     be authorized  for issuance  upon exercise in full of the Rights,  then, if
     the Board of  Directors  so elects,  the  thirty  (30) day period set forth
     above may be  extended  to the extent  necessary,  but not more than ninety
     (90) days  after the  Section  11(a)(ii)  Trigger  Date,  in order that the
     Company  may  seek  stockholder  approval  for  the  authorization  of such
     additional shares (such thirty (30) day period,  as it may be extended,  is
     herein called the  "Substitution  Period").  To the extent that the Company
     determines  that some  action need be taken  pursuant to the second  and/or
     third sentence of this Section  11(a)(iii),  the Company (x) shall provide,
     subject to Section  11(a)(ii)  hereof and the last sentence of this Section
     11(a)(iii)   hereof,   that  such  action  shall  apply  uniformly  to  all
     outstanding  Rights and (y) may  suspend the  

<PAGE>
                                                                              32



     exercisability  of the  Rights  until the  expiration  of the  Substitution
     Period in order to seek any  authorization  of additional  shares and/or to
     decide the  appropriate  form of  distribution  to be made pursuant to such
     second  sentence and to determine  the value  thereof.  In the event of any
     such suspension, the Company shall issue a public announcement stating that
     the exercisability of the Rights has been temporarily suspended, as well as
     a public  announcement  at such  time as the  suspension  is no  longer  in
     effect. For purposes of this Section 11(a)(iii), the value of the shares of
     Common  Stock shall be the current per share  market  price (as  determined
     pursuant to Section 11(d)(i)) on the Section 11(a)(ii) Trigger Date and the
     per share or  fractional  value of any "Common Stock  equivalent"  shall be
     deemed to equal the current per share market price of the Common Stock. The
     Board of  Directors  of the  Company  may,  but shall not be  required  to,
     establish  procedures  to  allocate  the right to receive  shares of Common
     Stock upon the exercise of the Rights among  holders of Rights  pursuant to
     this Section 11(a)(iii).

     In case the  Company  shall fix a record  date for the  issuance of rights,
options or warrants  to all holders of  Preferred  Stock  entitling  them (for a
period expiring within 45 calendar days after such record 

<PAGE>
                                                                              33



date) to subscribe for or purchase  Preferred  Stock (or shares  having  similar
rights, privileges and preferences as the Preferred Stock ("equivalent preferred
shares")) or securities convertible into Preferred Stock or equivalent preferred
shares at a price per share of Preferred  Stock or equivalent  preferred  shares
(or having a conversion  price per share, if a security  convertible into shares
of Preferred  Stock or equivalent  preferred  shares) less than the then current
per share market price of the Preferred  Stock  (determined  pursuant to Section
11(d) hereof) on such record date, the Purchase Price to be in effect after such
record date shall be  determined  by  multiplying  the Purchase  Price in effect
immediately  prior to such  record date by a fraction,  the  numerator  of which
shall be the number of shares of Preferred Stock and equivalent preferred shares
outstanding on such record date plus the number of shares of Preferred Stock and
equivalent  preferred  shares which the  aggregate  offering  price of the total
number of shares of Preferred Stock and/or equivalent  preferred shares so to be
offered  (and/or  the  aggregate  initial  conversion  price of the  convertible
securities so to be offered) would  purchase at such current  market price,  and
the  denominator  of which shall be the number of shares of Preferred  Stock and
equivalent  preferred shares  outstanding on such record date plus the number of
additional  shares of Preferred Stock and/or  

<PAGE>
                                                                              34



equivalent  preferred shares to be offered for subscription or purchase (or into
which the  convertible  securities so to be offered are initially  convertible);
provided,  however, that in no event shall the consideration to be paid upon the
exercise  of one Right be less  than the  aggregate  par value of the  shares of
capital stock of the Company  issuable upon exercise of one Right.  In case such
subscription  price may be paid in a consideration part or all of which shall be
in a form  other  than  cash,  the  value  of  such  consideration  shall  be as
determined  in good  faith  by the  Board of  Directors  of the  Company,  whose
determination  shall be  described in a statement  filed with the Rights  Agent.
Shares of Preferred Stock and equivalent  preferred  shares owned by or held for
the account of the Company  shall not be deemed  outstanding  for the purpose of
any such computation. Such adjustment shall be made successively whenever such a
record date is fixed; and in the event that such rights, options or warrants are
not so issued,  the Purchase  Price shall be adjusted to be the  Purchase  Price
which would then be in effect if such record date had not been fixed.

     In  case  the  Company  shall  fix  a  record  date  for  the  making  of a
distribution  to  all  holders  of  the  Preferred  Stock  (including  any  such
distribution  made in  connection  with a  consolidation  or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a

                                                                              35



regular  quarterly  cash dividend or a dividend  payable in Preferred  Stock) or
subscription  rights or warrants  (excluding  those referred to in Section 11(b)
hereof),  the  Purchase  Price to be in effect  after such  record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction,  the numerator of which shall be the then current per
share market price of the Preferred Stock (determined  pursuant to Section 11(d)
hereof) on such record date,  less the fair market value (as  determined in good
faith by the Board of  Directors  of the Company  whose  determination  shall be
described  in a  statement  filed with the Rights  Agent) of the  portion of the
assets or evidences of indebtedness so to be distributed or of such subscription
rights  or  warrants  applicable  to one  share  of  Preferred  Stock,  and  the
denominator  of which shall be such current per share  market price  (determined
pursuant to Section  11(d) hereof) of the Preferred  Stock;  provided,  however,
that in no event  shall the  consideration  to be paid upon the  exercise of one
Right be less than the aggregate par value of the shares of capital stock of the
Company to be issued upon exercise of one Right.  Such adjustments shall be made
successively  whenever  such a record date is fixed;  and in the event that such
distribution  is not so made,  the Purchase  Price shall again be adjusted to be
the  Purchase  Price  which  would then be in effect if such record date had not
been fixed.

                                                                              36



     Except as otherwise  provided  herein,  for the purpose of any  computation
hereunder,  the "current per share market  price" of any security (a  "Security"
for the purpose of this Section  11(d)(i)) on any date shall be deemed to be the
average  of the  daily  closing  prices  per share of such  Security  for the 30
consecutive Trading Days (as such term is hereinafter defined) immediately prior
to such date;  provided,  however,  that in the event that the current per share
market  price of the  Security  is  determined  during a  period  following  the
announcement by the issuer of such Security of (A) a dividend or distribution on
such Security payable in shares of such Security or securities  convertible into
such shares,  or (B) any subdivision,  combination or  reclassification  of such
Security,  and prior to the expiration of 30 Trading Days after the  ex-dividend
date for such dividend or distribution, or the record date for such subdivision,
combination  or  reclassification,  then, and in each such case, the current per
share market price shall be appropriately adjusted to reflect the current market
price per share  equivalent  of such  Security.  The closing  price for each day
shall be the last sale price,  regular way, or, in case no such sale takes place
on such day,  the average of the closing bid and asked  prices,  regular way, in
either case as  reported by the  principal  consolidated  transaction  reporting
system with respect to securities  listed or admitted to trading on the New 

<PAGE>
                                                                              37



York Stock  Exchange or, if the Security is not listed or admitted to trading on
the  New  York  Stock  Exchange,  as  reported  in  the  principal  consolidated
transaction  reporting system with respect to securities listed on the principal
national  securities  exchange  on which the  Security  is listed or admitted to
trading or, if the Security is not listed or admitted to trading on any national
securities exchange,  the last quoted price or, if not so quoted, the average of
the high bid and low asked prices in the over-the-counter market, as reported by
NASDAQ or such other system then in use, or, if on any such date the Security is
not quoted by any such  organization,  the  average of the closing bid and asked
prices  as  furnished  by a  professional  market  maker  making a market in the
Security  selected by the Board of Directors of the Company.  The term  "Trading
Day" shall mean a day on which the  principal  national  securities  exchange on
which the Security is listed or admitted to trading is open for the  transaction
of  business  or, if the  Security  is not listed or  admitted to trading on any
national securities exchange, a Business Day.

     For the purpose of any  computation  hereunder,  if the Preferred  Stock is
publicly  traded,  the "current per share market price" of the  Preferred  Stock
shall be determined in accordance with the method set forth in Section 11(d)(i).
If the Preferred  Stock is not publicly  traded but the Common Stock is publicly

<PAGE>
                                                                              38



traded,  the "current per share market  price" of the  Preferred  Stock shall be
conclusively deemed to be the current per share market price of the Common Stock
as  determined   pursuant  to  Section  11(d)(i)   multiplied  by  one  thousand
(appropriately  adjusted to reflect any stock split,  stock  dividend or similar
transaction  occurring  after the date hereof).  If neither the Common Stock nor
the Preferred Stock is publicly  traded,  "current per share market price" shall
mean the fair  value  per  share as  determined  in good  faith by the  Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent.

     No  adjustment  in  the  Purchase  Price  shall  be  required  unless  such
adjustment  would require an increase or decrease of at least 1% in the Purchase
Price;  provided,  however, that any adjustments which by reason of this Section
11(e) are not  required  to be made  shall be  carried  forward  and taken  into
account in any subsequent  adjustment.  All  calculations  under this Section 11
shall be made to the  nearest  cent or to the nearest  one  ten-thousandth  of a
share of Preferred  Stock or share of Common Stock or other share or security as
the case may be.  Notwithstanding  the first sentence of this Section 11(e), any
adjustment  required by this  Section 11 shall be made no later than the earlier
of (i)  three  years  from  the  date of the  transaction  which  requires  such
adjustment  or (ii) the

                                                                              39



date of the expiration of the right to exercise any Rights.

     If as a result of an adjustment made pursuant to Section 11(a) hereof,  the
holder of any Right  thereafter  exercised  shall become entitled to receive any
shares  of  capital  stock  of the  Company  other  than  the  Preferred  Stock,
thereafter  the Purchase Price and the number of such other shares so receivable
upon exercise of a Right shall be subject to  adjustment  from time to time in a
manner and on terms as nearly  equivalent as practicable to the provisions  with
respect to the Preferred Stock contained in Sections 11(a), 11(b), 11(c), 11(e),
11(h), 11(i) and 11(m) and the provisions of Sections 7, 9, 10, 13 and 14 hereof
with respect to the Preferred  Stock shall apply on like terms to any such other
shares.

     All Rights  originally  issued by the Company  subsequent to any adjustment
made to the Purchase Price  hereunder  shall evidence the right to purchase,  at
the adjusted  Purchase Price,  the number of one  one-thousandths  of a share of
Preferred  Stock  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

     Unless the Company shall have exercised its election as provided in Section
11(i),  upon  each  adjustment  of  the  Purchase  Price  as  a  result  of  the
calculations made in Sections 11(b) and (c), each Right

outstanding  immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase,  at the adjusted  Purchase Price, that number of
one one-thousandths of a share of Preferred Stock (calculated to the nearest one
ten-  thousandth of a share of Preferred  Stock) obtained by (i) multiplying (x)
the number of one  one-thousandths  of a share  covered  by a Right  immediately
prior to such adjustment by (y) the Purchase Price in effect  immediately  prior
to such  adjustment  of the  Purchase  Price and (ii)  dividing  the  product so
obtained by the Purchase Price in effect  immediately  after such  adjustment of
the Purchase Price.

     The  Company  may  elect on or  after  the  date of any  adjustment  of the
Purchase  Price  to  adjust  the  number  of  Rights,  in  substitution  for any
adjustment in the number of one  one-thousandths  of a share of Preferred  Stock
purchasable upon the exercise of a Right.  Each of the Rights  outstanding after
such  adjustment of the number of Rights shall be exercisable  for the number of
one  one-thousandths  of a share  of  Preferred  Stock  for  which  a Right  was
exercisable  immediately  prior to such  adjustment.  Each  Right held of record
prior to such  adjustment  of the number of Rights  shall  become that number of
Rights (calculated to the nearest one  ten-thousandth)  obtained by dividing the
Purchase Price 

<PAGE>
                                                                              41


in effect  immediately prior to adjustment of the Purchase Price by the Purchase
Price in effect  immediately after adjustment of the Purchase Price. The Company
shall make a public announcement of its election to adjust the number of Rights,
indicating  the record date for the  adjustment,  and, if known at the time, the
amount of the  adjustment to be made.  This record date may be the date on which
the  Purchase  Price  is  adjusted  or any day  thereafter,  but,  if the  Right
Certificates have been issued,  shall be at least 10 days later than the date of
the public  announcement.  If Right  Certificates  have been  issued,  upon each
adjustment of the number of Rights  pursuant to this Section 11(i),  the Company
may, as promptly as practicable, cause to be distributed to holders of record of
Right Certificates on such record date Right Certificates evidencing, subject to
Section 14 hereof, the additional Rights to which such holders shall be entitled
as a result of such adjustment, or, at the option of the Company, shall cause to
be distributed to such holders of record in substitution and replacement for the
Right  Certificates  held by such holders prior to the date of  adjustment,  and
upon  surrender  thereof,  if required by the  Company,  new Right  Certificates
evidencing  all the Rights to which such  holders  shall be entitled  after such
adjustment.  Right  Certificates so to be distributed shall be issued,  executed
and  countersigned  in the manner provided for herein and shall be registered in
the names of the  holders of 

<PAGE>
                                                                              42



record  of  Right  Certificates  on the  record  date  specified  in the  public
announcement.

     Irrespective  of any  adjustment  or  change in the  Purchase  Price or the
number of one  one-thousandths  of a share of Preferred  Stock issuable upon the
exercise of the Rights, the Right Certificates theretofore and thereafter issued
may continue to express the Purchase Price and the number of one one-thousandths
of a share  of  Preferred  Stock  which  were  expressed  in the  initial  Right
Certificates issued hereunder.

     Before  taking  any action  that would  cause an  adjustment  reducing  the
Purchase Price below the then par value, if any, of the Preferred Stock or other
shares of capital stock issuable upon exercise of the Rights,  the Company shall
take any corporate action which may, in the opinion of its counsel, be necessary
in  order  that the  Company  may  validly  and  legally  issue  fully  paid and
nonassessable  shares of Preferred  Stock or other such shares at such  adjusted
Purchase Price.

     In any case in which this Section 11 shall  require that an  adjustment  in
the Purchase Price be made effective as of a record date for a specified  event,
the Company may elect to defer until the occurrence of such event the issuing to
the holder of any Right  exercised after such record date of the Preferred Stock
and other capital stock or securities of the Company, if any, issuable upon such
exercise  over  and  above  the  Preferred  Stock  and  other  capital  stock or
securities of the Company,  if any,  issuable upon such exercise 

<PAGE>
                                                                              43


over and above the Preferred  Stock and other capital stock or securities of the
Company,  if any, issuable upon such exercise on the basis of the Purchase Price
in effect prior to such adjustment;  provided,  however,  that the Company shall
deliver to such  holder a due bill or other  appropriate  instrument  evidencing
such holder's right to receive such additional shares upon the occurrence of the
event requiring such adjustment.

     Anything in this  Section 11 to the contrary  notwithstanding,  the Company
shall be entitled to make such  reductions in the Purchase Price, in addition to
those  adjustments  expressly  required by this Section 11, as and to the extent
that it in its sole discretion shall determine to be advisable in order that any
consolidation or subdivision of the Preferred Stock, issuance wholly for cash of
any shares of Preferred  Stock at less than the current  market price,  issuance
wholly  for cash or  Preferred  Stock or  securities  which by their  terms  are
convertible  into or exchangeable  for Preferred  Stock,  dividends on Preferred
Stock  payable in shares of  Preferred  Stock or issuance of rights,  options or
warrants referred to hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Stock shall not be taxable to such stockholders.

     Anything in this  Agreement to the contrary  notwithstanding,  in the event
that at any time after the date of this Agreement and prior to the  

<PAGE>
                                                                              44



Distribution  Date,  the Company  shall (i)  declare or pay any  dividend on the
Common Stock payable in Common Stock or (ii) effect a  subdivision,  combination
or consolidation of the Common Stock (by  reclassification  or otherwise than by
payment of a dividend  payable in Common  Stock) into a greater or lesser number
of Common Stock,  then in any such case,  the number of Rights  associated  with
each share of Common Stock then outstanding,  or issued or delivered thereafter,
shall be  proportionately  adjusted  so that the  number  of  Rights  thereafter
associated  with each share of Common Stock following any such event shall equal
the result  obtained by multiplying  the number of Rights  associated  with each
share of  Common  Stock  immediately  prior  to such  event  by a  fraction  the
numerator  of which  shall  be the  total  number  of  shares  of  Common  Stock
outstanding immediately prior to the occurrence of the event and the denominator
of which  shall be the  total  number of  shares  of  Common  Stock  outstanding
immediately following the occurrence of such event.

     The Company agrees that, after the earlier of the Distribution  Date or the
Stock  Acquisition  Date, it will not, except as permitted by Sections 23, 24 or
27 hereof,  take (or permit  any  Subsidiary  to take) any action if at the time
such action is taken it is reasonably foreseeable that such action will diminish
substantially or eliminate the benefits intended to be afforded by the Rights.

     Section  Certificate  of  Adjusted  Purchase  Price or  Number  of  Shares.
Whenever  an  adjustment  is made as  provided  in Section 11 or 13 hereof,  the
Company shall promptly (a) prepare a certificate  setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (b) file with
the  Rights  Agent and with each  transfer  agent  for the  Common  Stock or the
Preferred Stock a copy of such  certificate and (c) mail a brief summary thereof
to each holder of a Right  Certificate in accordance  with Section 25 hereof (if
so required under Section 25 hereof).  The Rights Agent shall be fully protected
in relying on any such certificate and on any adjustment  therein  contained and
shall not be deemed to have knowledge of any such adjustment unless and until it
shall have received such certificate.

     Section  Consolidation,  Merger or Sale or  Transfer  of Assets or Earnings
Power.  (a) In the event,  directly or indirectly,  at any time after any Person
has become an Acquiring  Person,  (i) the Company  shall merge with and into any
other Person,  (ii) any Person shall consolidate with the Company, or any Person
shall merge with and into the Company and the Company shall be the continuing or
surviving corporation of such merger and, in connection with such merger, all or
part of the Common Stock shall be changed  into or exchanged  for stock or other
securities  of any  other  Person  (or of the  Company)  or  cash  or any  other
property,  or (iii) the Company shall sell or otherwise transfer (or one or more
of  its  Subsidiaries  shall  sell  or

otherwise  transfer),  in one or more  transactions,  assets  or  earning  power
aggregating  50% or more of the assets or earning  power of the  Company and its
Subsidiaries  (taken as a whole) to any other Person  (other than the Company or
one or more of its wholly-owned Subsidiaries), then upon the first occurrence of
such event, proper provision shall be made so that: (A) each holder of record of
a Right (other than Rights which have become void pursuant to Section 11(a)(ii))
shall thereafter have the right to receive, upon the exercise thereof at a price
equal to the  then  current  Purchase  Price  multiplied  by the  number  of one
one-thousandths  of a share of Preferred Stock for which a Right was exercisable
(whether or not such Right was then  exercisable)  immediately prior to the time
that any Person first became an Acquiring Person (each as subsequently  adjusted
thereafter pursuant to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m)),
in accordance  with the terms of this Agreement and in lieu of Preferred  Stock,
such  number  of  validly  issued,  fully  paid and  non-assessable  and  freely
tradeable  shares of Common Stock of the Principal Party (as defined herein) not
subject to any liens,  encumbrances,  rights of first  refusal or other  adverse
claims,  as shall be equal to the result  obtained by (1)  multiplying  the then
current  Purchase  Price  by the  number  of one  one-thousandths  of a share of
Preferred Stock for which a Right was exercisable  immediately prior to the time
that any Person  first  became an  Acquiring  Person (as  subsequently  adjusted
thereafter pursuant to Sections 11(a)(i),  11(b),

                                                                              47



11(c),  11(h), 11(i) and 11(m)) and (2) dividing that product by 50% of the then
current  per share  market  price of the Common  Stock of such  Principal  Party
(determined  pursuant to Section 11(d)(i) hereof) on the date of consummation of
such consolidation,  merger, sale or transfer;  provided that the Purchase Price
and the number of shares of Common Stock of such  Principal  Party issuable upon
exercise of each Right shall be further adjusted as provided in Section 11(f) of
this  Agreement  to reflect any events  occurring  in respect of such  Principal
Party after the date of the such consolidation,  merger,  sale or transfer;  (B)
such Principal Party shall thereafter be liable for, and shall assume, by virtue
of such consolidation,  merger, sale or transfer, all the obligations and duties
of the  Company  pursuant  to this  Agreement;  (C)  the  term  "Company"  shall
thereafter be deemed to refer to such  Principal  Party;  and (D) such Principal
Party shall take such steps (including, but not limited to, the reservation of a
sufficient  number of its shares of Common  Stock in  accordance  with Section 9
hereof) in connection with such  consummation of any such  transaction as may be
necessary to assure that the provisions  hereof shall  thereafter be applicable,
as nearly as  reasonably  may be, in relation to the shares of its Common  Stock
thereafter deliverable upon the exercise of the Rights;  provided that, upon the
subsequent  occurrence of any consolidation,  merger, sale or transfer of assets
or other  extraordinary  transaction  in respect of such Principal  Party,  each
holder of a Right shall  thereupon  be entitled to receive,  upon  

<PAGE>
                                                                              48



exercise  of a Right and  payment  of the  Purchase  Price as  provided  in this
Section 13(a), such cash, shares, rights, warrants and other property which such
holder would have been entitled to receive had such holder,  at the time of such
transaction,  owned the Common Stock of the Principal Party  receivable upon the
exercise of a Right  pursuant to this Section 13(a),  and such  Principal  Party
shall take such steps (including,  but not limited to,  reservation of shares of
stock) as may be  necessary to permit the  subsequent  exercise of the Rights in
accordance  with the terms hereof for such cash,  shares,  rights,  warrants and
other property.

     (b) "Principal Party" shall mean

          (i) in the  case of any  transaction  described  in (i) or (ii) of the
     first  sentence of Section 13(a) hereof:  (A) the Person that is the issuer
     of the  securities  into which the shares of Common Stock are  converted in
     such merger or  consolidation,  or, if there is more than one such  issuer,
     the issuer the shares of Common Stock of which have the greatest  aggregate
     market value of shares outstanding,  or (B) if no securities are so issued,
     (x) the  Person  that is the  other  party to the  merger,  if such  Person
     survives said merger, or, if there is more than one such Person, the Person
     the shares of Common  Stock of which  have the  greatest  aggregate  market
     value of shares outstanding or (y) if the Person that is the other party to
     the merger does not survive  the merger,  the Person that does  survive the
     merger  (including the Company if it

                                                                              49



     survives) or (z) the Person resulting from the consolidation; and

          (ii) in the case of any  transaction  described  in (iii) of the first
     sentence in Section  13(a) hereof,  the Person that is the party  receiving
     the greatest portion of the assets or earning power transferred pursuant to
     such  transaction  or  transactions,  or, if each Person that is a party to
     such transaction or transactions receives the same portion of the assets or
     earning  power so  transferred  or if the  Person  receiving  the  greatest
     portion of the assets or earning power cannot be  determined,  whichever of
     such Persons as is the issuer of Common Stock having the greatest aggregate
     market value of shares outstanding;

provided,  however,  that in any such case  described  in the  foregoing  clause
(b)(i) or (b)(ii), if the Common Stock of such Person is not at such time or has
not been  continuously  over the  preceding  12-month  period  registered  under
Section 12 of the Exchange  Act, then (1) if such Person is a direct or indirect
Subsidiary  of  another  Person  the  Common  Stock  of which is and has been so
registered,  the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
and the Common Stocks of all of such persons have been so  registered,  the term
"Principal  Party"  shall refer to  whichever  of such  Persons is the issuer of
Common Stock having the greatest  aggregate market value of shares  outstanding,
or (3) if such  Person is owned,  directly  or  

<PAGE>
                                                                              50



indirectly, by a joint venture formed by two or more Persons that are not owned,
directly or indirectly,  by the same Person,  the rules set forth in clauses (1)
and (2)  above  shall  apply to each of the  owners  having an  interest  in the
venture as if the Person owned by the joint  venture was a Subsidiary of both or
all of such joint  venturers,  and the  Principal  Party in each such case shall
bear the  obligations  set  forth in this  Section  13 in the same  ratio as its
interest in such Person bears to the total of such interests.

     (c) The Company shall not consummate  any  consolidation,  merger,  sale or
transfer  referred to in Section  13(a) hereof  unless prior thereto the Company
and the Principal  Party  involved  therein shall have executed and delivered to
the Rights Agent an agreement confirming that the requirements of Sections 13(a)
and (b) hereof shall  promptly be performed in  accordance  with their terms and
that such consolidation,  merger, sale or transfer of assets shall not result in
a default by the  Principal  Party under this  Agreement  as the same shall have
been assumed by the Principal  Party  pursuant to Sections  13(a) and (b) hereof
and providing  that,  as soon as  practicable  after  executing  such  agreement
pursuant to this Section 13, the Principal Party will:

          (i) prepare and file a  registration  statement  under the  Securities
     Act,  if  necessary,   with  respect  to  the  Rights  and  the  securities
     purchasable  upon exercise of the Rights on an  appropriate  form,  use 

<PAGE>
                                                                              51



     its best efforts to cause such  registration  statement to become effective
     as soon as practicable  after such filing and use its best efforts to cause
     such  registration  statement to remain effective (with a prospectus at all
     times  meeting  the  requirements  of the  Securities  Act) until the Final
     Expiration  Date, and similarly  comply with  applicable  state  securities
     laws;

          (ii) use its best efforts,  if the Common Stock of the Principal Party
     shall be listed or admitted to trading on the New York Stock Exchange or on
     another  national  securities  exchange,  to list or admit to  trading  (or
     continue  the listing of) the Rights and the  securities  purchasable  upon
     exercise of the Rights on the New York Stock  Exchange  or such  securities
     exchange,  or, if the  Common  Stock of the  Principal  Party  shall not be
     listed or admitted to trading on the New York Stock  Exchange or a national
     securities exchange, to cause the Rights and the securities receivable upon
     exercise of the Rights to be reported by such other system then in use;

          (iii) deliver to holders of the Rights historical financial statements
     for the Principal Party which comply in all respects with the  requirements
     for registration on Form 10 (or any successor form) under the Exchange Act;
     and

          (iv)  obtain  waivers  of any rights of first  refusal  or  preemptive
     rights in respect of the Common

                                                                              52



     Stock  of  the  Principal  Party  subject  to  purchase  upon  exercise  of
     outstanding Rights.

     (d) In case the  Principal  Party has  provision  in any of its  authorized
securities or in its certificate of incorporation or by-laws or other instrument
governing its corporate  affairs,  which  provision would have the effect of (i)
causing such Principal  Party to issue (other than to holders of Rights pursuant
to  this  Section  13),  in  connection  with,  or  as  a  consequence  of,  the
consummation  of a transaction  referred to in this Section 13, shares of Common
Stock of such  Principal  Party at less than the then  current  market price per
share  thereof  (determined  pursuant  to Section  11(d)  hereof) or  securities
exercisable  for, or convertible  into,  Common Stock of such Principal Party at
less than such then current  market  price,  or (ii)  providing  for any special
payment,  tax or similar provision in connection with the issuance of the Common
Stock of such Principal Party pursuant to the provisions of Section 13, then, in
such event,  the Company  hereby agrees with each holder of Rights that it shall
not  consummate any such  transaction  unless prior thereto the Company and such
Principal  Party  shall  have  executed  and  delivered  to the  Rights  Agent a
supplemental  agreement  providing  that  the  provision  in  question  of  such
Principal  Party  shall  have been  cancelled,  waived or  amended,  or that the
authorized  securities shall be redeemed,  so that the applicable provision will
have no effect in connection  with, or as a

consequence of, the consummation of the proposed transaction.

     (e) The Company covenants and agrees that it shall not, at any time after a
Person first becomes an Acquiring  Person enter into any transaction of the type
contemplated  by (i) - (iii) of  Section  13(a)  hereof if (x) at the time of or
immediately  after  such   consolidation,   merger,   sale,  transfer  or  other
transaction  there are any rights,  warrants or other  instruments or securities
outstanding  or  agreements  in effect  which  would  substantially  diminish or
otherwise  eliminate  the  benefits  intended to be afforded by the Rights,  (y)
prior to,  simultaneously with or immediately after such consolidation,  merger,
sale,  transfer  of  other  transaction,  the  stockholders  of the  Person  who
constitutes,  or would  constitute,  the Principal Party for purposes of Section
13(a) hereof shall have received a distribution  of Rights  previously  owned by
such Person or any of its  Affiliates or Associates or (z) the form or nature of
organization of the Principal  Party would preclude or limit the  exercisability
of the Rights.

     Section  Fractional Rights and Fractional  Shares. The Company shall not be
required to issue fractions of Rights or to distribute Right  Certificates which
evidence  fractional Rights (except prior to the Distribution Date in accordance
with Section 11(n) hereof).  In lieu of such fractional  Rights,  there shall be
paid to the registered  holders of the Right  Certificates  with regard to which
such 

<PAGE>
                                                                              54



fractional  Rights would  otherwise be issuable,  an amount in cash equal to the
same fraction of the current market value of a whole Right.  For the purposes of
this  Section  14(a),  the  current  market  value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date on
which such  fractional  Rights would have been otherwise  issuable.  The closing
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day,  the average of the closing bid and asked  prices,
regular  way,  in  either  case  as  reported  in  the  principal   consolidated
transaction  reporting  system with respect to securities  listed or admitted to
trading  on the New York  Stock  Exchange  or, if the  Rights  are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated  transaction  reporting system with respect to securities listed on
the  principal  national  securities  exchange on which the Rights are listed or
admitted  to trading  or, if the Rights are not listed or admitted to trading on
any national  securities  exchange,  the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported  by NASDAQ or such other  system then in use or, if on any such date
the Rights are not quoted by any such  organization,  the average of the closing
bid and asked prices as furnished by a professional market maker making a market
in the Rights selected by the Board of Directors of the Company.  If on any such
date no such market  maker is making a market in the

Rights, the fair value of the Rights on such date as determined in good faith by
the Board of Directors of the Company shall be used.
 
     The Company  shall not be required to issue  fractions of  Preferred  Stock
(other than fractions which are integral  multiples of one  one-thousandth  of a
share  of  Preferred  Stock)  upon  exercise  of  the  Rights  or to  distribute
certificates  which evidence  fractional  shares of Preferred  Stock (other than
fractions  which are  integral  multiples  of one  one-thousandth  of a share of
Preferred  Stock).  Interests  in  fractions  of  Preferred  Stock  in  integral
multiples  of one  one-thousandth  of a share of  Preferred  Stock  may,  at the
election of the Company,  be evidenced by  depositary  receipts,  pursuant to an
appropriate  agreement  between  the Company  and a  depositary  selected by it;
provided,  that such agreement shall provide that the holders of such depositary
receipts shall have all the rights, privileges and preferences to which they are
entitled  as  beneficial  owners  of the  Preferred  Stock  represented  by such
depositary  receipts.  In lieu of fractional  shares of Preferred Stock that are
not integral  multiples of one one-thousandth of a share of Preferred Stock, the
Company shall pay to the registered  holders of Right  Certificates  at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current  market value of one share of Preferred  Stock.  For the
purposes of this Section 14(b), the current market value of a share of Preferred
Stock shall be the closing

                                                                              56



price of a share of Preferred Stock (as determined  pursuant to Section 11(d)(i)
hereof) for the Trading Day immediately prior to the date of such exercise.

     The Company  shall not be required to issue  fractions  of shares of Common
Stock or to distribute  certificates which evidence  fractional shares of Common
Stock upon the exercise or exchange of Rights. In lieu of such fractional shares
of Common Stock,  the Company shall pay to the  registered  holders of the Right
Certificates  with regard to which such fractional  shares of Common Stock would
otherwise  be  issuable  in an amount in cash equal to the same  fraction of the
current  market  value of a whole  share  of  Common  Stock  (as  determined  in
accordance with Section 14(a) hereof) for the Trading Day  immediately  prior to
the date of such exercise or exchange.

     The holder of a Right by the acceptance of the Right  expressly  waives his
right to receive any fractional Rights or any fractional shares upon exercise of
a Right (except as provided above).

     Section  Rights  of  Action.  All  rights  of  action  in  respect  of this
Agreement,  excepting  the  rights of action  given to the  Rights  Agent  under
Section 18 hereof, are vested in the respective  registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock);  and any registered holder of any Right Certificate (or, prior to
the Distribution  Date, of the Common Stock),  without the consent of the Rights
Agent  or of the  holder  of any  other  Right  Certificate  

<PAGE>
                                                                              57



(or, prior to the Distribution Date, of the Common Stock), on his own behalf and
for his own  benefit,  may  enforce,  and may  institute  and maintain any suit,
action or proceeding against the Company to enforce, or otherwise act in respect
of, his right to exercise the Rights  evidenced by such Right  Certificate  (or,
prior to the  Distribution  Date,  such Common Stock) in the manner  provided in
such Right Certificate and in this Agreement.  Without limiting the foregoing or
any remedies available to the holders of Rights, it is specifically acknowledged
that the  holders  of Rights  would not have an  adequate  remedy at law for any
breach of this  Agreement  and will be entitled to specific  performance  of the
obligations under, and injunctive relief against actual or threatened violations
of, the obligations of any Person subject to this Agreement.

     Section  Agreement of Right Holders.  Every holder of a Right, by accepting
the same,  consents  and agrees with the  Company and the Rights  Agent and with
every other holder of a Right that:

          prior to the Distribution  Date, the Rights will be transferable  only
     in connection with the transfer of the Common Stock;

          after the Distribution  Date, the Right  Certificates are transferable
     only on the registry books of the Rights Agent if surrendered at the office
     or agency of the Rights Agent designated for such purpose, duly endorsed or
     accompanied by a proper instrument of transfer; and

<PAGE>
                                                                              58



          the  Company  and the  Rights  Agent may deem and treat the  Person in
     whose name the Right  Certificate (or, prior to the Distribution  Date, the
     Common Stock  certificate)  is registered as the absolute owner thereof and
     of the Rights evidenced thereby (notwithstanding any notations of ownership
     or writing on the Right  Certificates or the Common Stock  certificate made
     by anyone  other than the  Company or the  Rights  Agent) for all  purposes
     whatsoever,  and neither the Company nor the Rights Agent shall be affected
     by any notice to the contrary.

     Section Right  Certificate  Holder Not Deemed a Stockholder.  No holder, as
such, of any Right Certificate  shall be entitled to vote,  receive dividends or
be  deemed  for any  purpose  the  holder  of the  Preferred  Stock or any other
securities  of the Company  which may at any time be issuable on the exercise of
the Rights  represented  thereby,  nor shall anything contained herein or in any
Right  Certificate  be  construed  to  confer  upon  the  holder  of  any  Right
Certificate,  as such,  any of the rights of a stockholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
stockholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
stockholders (except as provided in this Agreement),  or to receive dividends or
subscription  rights,  or  otherwise,  until the Rights

                                                                              59



evidenced by such Right Certificate shall have been exercised in accordance with
the provisions hereof.

     Section  Concerning  the Rights  Agent.  The  Company  agrees to pay to the
Rights Agent reasonable  compensation for all services  rendered by it hereunder
and, from time to time, on demand of the Rights Agent,  its reasonable  expenses
and counsel  fees and other  disbursements  incurred in the  administration  and
execution  of this  Agreement  and the exercise  and  performance  of its duties
hereunder.  The Company  also agrees to  indemnify  the Rights Agent for, and to
hold it harmless  against,  any loss,  liability  or expense,  incurred  without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection  with the  acceptance
and  administration  of this  Agreement,  including  the costs and  expenses  of
defending  against  any  claim  of  liability  arising  therefrom,  directly  or
indirectly.

     The Rights Agent shall be protected and shall incur no liability for, or in
respect of any action taken,  suffered or omitted by it in connection  with, its
administration  of this  Agreement  in reliance  upon any Right  Certificate  or
certificate for the Preferred  Stock or Common Stock or for other  securities of
the  Company,   instrument  of  assignment  or  transfer,   power  of  attorney,
endorsement,   affidavit,  letter,  notice,  direction,   consent,  certificate,
statement,  or other  paper or  document  believed by it to be genuine and to be
signed, executed and, where necessary,

                                                                              60



verified or acknowledged, by the proper Person or Persons, or otherwise upon the
advice of counsel as set forth in Section 20 hereof.

     Section  Merger or  Consolidation  or Change of Name of Rights  Agent.  Any
corporation  into which the Rights  Agent or any  successor  Rights Agent may be
merged or with which it may be consolidated,  or any corporation  resulting from
any merger or  consolidation  to which the Rights Agent or any successor  Rights
Agent shall be a party, or any  corporation  succeeding to the stock transfer or
corporate trust powers of the Rights Agent or any successor Rights Agent,  shall
be the successor to the Rights Agent under this Agreement  without the execution
or  filing  of any paper or any  further  act on the part of any of the  parties
hereto;  provided,  that such corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof. In case at the
time such  successor  Rights Agent shall  succeed to the agency  created by this
Agreement,  any of the Right  Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of the
predecessor  Rights Agent and deliver such Right  Certificates so countersigned;
and in case at that  time any of the  Right  Certificates  shall  not have  been
countersigned,   any  successor   Rights  Agent  may   countersign   such  Right
Certificates  either in the name of the predecessor  Rights Agent or in the name
of the  successor  Rights Agent;  and in all such cases such Right  Certificates
shall  have  the full  

<PAGE>
                                                                              61



force provided in the Right Certificates and in this Agreement.

     In case at any time the name of the Rights  Agent  shall be changed  and at
such time any of the Right  Certificates  shall have been  countersigned but not
delivered the Rights Agent may adopt the  countersignature  under its prior name
and deliver Right Certificates so countersigned; and in case at that time any of
the Right Certificates shall not have been  countersigned,  the Rights Agent may
countersign such Right  Certificates  either in its prior name or in its changed
name and in all such  cases such  Right  Certificates  shall have the full force
provided in the Right Certificates and in this Agreement.

     Section Duties of Rights Agent.  The Rights Agent undertakes the duties and
obligations  imposed by this Agreement upon the following  terms and conditions,
by all of which the  Company  and the  holders of Right  Certificates,  by their
acceptance thereof, shall be bound:

          The Rights  Agent may  consult  with legal  counsel  (who may be legal
     counsel for the Company), and the opinion of such counsel shall be full and
     complete  authorization and protection to the Rights Agent as to any action
     taken or omitted by it in good faith and in accordance with such opinion.

          Whenever in the  performance  of its duties under this  Agreement  the
     Rights Agent shall deem it  necessary or desirable  that any fact or matter
     be proved or  established  by the Company  prior to taking or 

<PAGE>
                                                                              62



     suffering any action hereunder,  such fact or matter (unless other evidence
     in respect thereof be herein  specifically  prescribed) may be deemed to be
     conclusively  proved and established by a certificate  signed by any one of
     the Chairman of the Board of Directors,  the President, any Vice President,
     the Treasurer, the Controller or the Secretary of the Company and delivered
     to the Rights Agent;  and such certificate  shall be full  authorization to
     the Rights Agent for any action taken or suffered in good faith by it under
     the provisions of this Agreement in reliance upon such certificate.

          The Rights  Agent  shall be liable  hereunder  to the  Company and any
     other Person only for its own negligence, bad faith or wilful misconduct.

          The  Rights  Agent  shall not be liable for or by reason of any of the
     statements of fact or recitals  contained in this Agreement or in the Right
     Certificates (except its countersignature thereof) or be required to verify
     the same,  but all such  statements and recitals are and shall be deemed to
     have been made by the Company only.

          The Rights Agent shall not be under any  responsibility  in respect of
     the validity of this Agreement or the execution and delivery hereof (except
     the due execution hereof by the Rights Agent) or in respect of the validity
     or  execution  of  any  Right  Certificate  (except  its   countersignature
     thereof);  nor 

<PAGE>
                                                                              63



     shall it be  responsible  for any breach by the Company of any  covenant or
     condition  contained  in this  Agreement or in any Right  Certificate;  nor
     shall it be responsible for any change in the  exercisability of the Rights
     (including the Rights becoming void pursuant to Section  11(a)(ii)  hereof)
     or any adjustment in the terms of the Rights (including the manner,  method
     or amount  thereof)  provided  for in Sections 3, 11, 13, 23 and 24, or the
     ascertaining  of the  existence of facts that would require any such change
     or adjustment  (except with respect to the exercise of Rights  evidenced by
     Right  Certificates  after receipt of a certificate  furnished  pursuant to
     Section 12, describing such change or adjustment);  nor shall it by any act
     hereunder  be  deemed  to make any  representation  or  warranty  as to the
     authorization  or  reservation  of any shares of  Preferred  Stock or other
     securities to be issued pursuant to this Agreement or any Right Certificate
     or as to whether any shares of Preferred  Stock or other  securities  will,
     when   issued,   be  validly   authorized   and  issued,   fully  paid  and
     nonassessable.

          The Company  agrees that it will  perform,  execute,  acknowledge  and
     deliver or cause to be performed, executed,  acknowledged and delivered all
     such further and other acts,  instruments  and assurances as may reasonably
     be required by the Rights Agent for the carrying out or  performing  by the
     Rights Agent of the provisions of this Agreement.

                                                                              64



          The  Rights  Agent  is  hereby   authorized  and  directed  to  accept
     instructions  with respect to the performance of its duties  hereunder from
     any  person  reasonably  believed  by  the  Rights  Agent  to be one of the
     Chairman of the Board of  Directors,  the  President,  the Chief  Financial
     Officer or the Secretary of the Company,  and to apply to such officers for
     advice or instructions  in connection with its duties,  and it shall not be
     liable for any action  taken or suffered by it in good faith in  accordance
     with  instructions  of any such  officer  or for any delay in acting  while
     waiting for those  instructions.  Any  application  by the Rights Agent for
     written  instructions  from the  Company  may,  at the option of the Rights
     Agent,  set forth in writing any action  proposed to be taken or omitted by
     the Rights  Agent under this  Agreement  and the date on and/or after which
     such action shall be taken or such omission shall be effective.  The Rights
     Agent  shall not be liable for any  action  taken by, or  omission  of, the
     Rights Agent in accordance with a proposal included in any such application
     on or after the date specified in such application (which date shall not be
     less than five  Business  Days after the date any  officer  of the  Company
     actually  receives  such  application,  unless any such officer  shall have
     consented in writing to an earlier date)  unless,  prior to taking any such
     action (or the effective date in the case of an omission), the Rights Agent
     shall have received  written  instructions 

<PAGE>
                                                                              65



     in  response  to such  application  specifying  the  action  to be taken or
     omitted.

          The Rights Agent and any stockholder, director, officer or employee of
     the  Rights  Agent  may  buy,  sell or deal in any of the  Rights  or other
     securities  of  the  Company  or  become  pecuniarily   interested  in  any
     transaction  in which the Company may be  interested,  or contract  with or
     lend money to the Company or otherwise act as fully and freely as though it
     were not Rights Agent under this  Agreement.  Nothing herein shall preclude
     the Rights  Agent from acting in any other  capacity for the Company or for
     any other legal entity.

          The Rights  Agent may execute and exercise any of the rights or powers
     hereby  vested in it or perform any duty  hereunder  either itself or by or
     through  its  attorneys  or  agents,  and the  Rights  Agent  shall  not be
     answerable or accountable  for any act,  default,  neglect or misconduct of
     any such attorneys or agents or for any loss to the Company  resulting from
     any such act, default, neglect or misconduct,  provided reasonable care was
     exercised in the selection and continued employment thereof.

          If, with respect to any Rights  Certificate  surrendered to the Rights
     Agent for exercise or transfer,  the  certificate  contained in the form of
     assignment  or the form of election  to  purchase  set forth on the reverse
     thereof,  as the case may be, has not been  completed to certify the holder
     is not an 

<PAGE>
                                                                              66



     Acquiring Person (or an Affiliate or Associate  thereof),  the Rights Agent
     shall not take any further action with respect to such  requested  exercise
     or transfer without first consulting with the Company.

     Section  Change of Rights Agent.  The Rights Agent or any successor  Rights
Agent may resign and be discharged  from its duties under this Agreement upon 30
days' notice in writing  mailed to the Company and to each transfer agent of the
Common Stock or Preferred Stock by registered or certified mail, and,  following
the Distribution  Date, to the holders of the Right  Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
30 days'  notice in  writing,  mailed to the Rights  Agent or  successor  Rights
Agent,  as the case may be, and to each  transfer  agent of the Common  Stock or
Preferred Stock by registered or certified mail, and, following the Distribution
Date,  to the holders of the Right  Certificates  by  first-class  mail.  If the
Rights Agent shall resign or be removed or shall otherwise  become  incapable of
acting,  the Company  shall  appoint a  successor  to the Rights  Agent.  If the
Company  shall  fail to make such  appointment  within a period of 30 days after
giving  notice of such removal or after it has been  notified in writing of such
resignation or incapacity by the resigning or  incapacitated  Rights Agent or by
the holder of a Right Certificate (who shall, with such notice, submit his Right
Certificate  for inspection by the Company),  then the registered  holder of any
Right  Certificate  may apply to any  court of  competent  jurisdiction  

<PAGE>
                                                                              67



for the appointment of a new Rights Agent. Any successor  Rights Agent,  whether
appointed  by  the  Company  or by  such a  court,  shall  be (A) a  corporation
organized  and doing  business  under the laws of the United States or any State
thereof,  which is  authorized  under such laws to exercise  corporate  trust or
stock transfer powers and is subject to supervision or examination by federal or
state  authority and which has at the time of its  appointment as Rights Agent a
combined  capital and surplus of at least $50 million or (B) an  affiliate  of a
corporation  described in clause (A) of this sentence.  After  appointment,  the
successor Rights Agent shall be vested with the same powers,  rights, duties and
responsibilities  as if it had been  originally  named as Rights  Agent  without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the  purpose.  Not later than the  effective  date of any such  appointment  the
Company shall file notice thereof in writing with the  predecessor  Rights Agent
and each transfer agent of the Common Stock or Preferred Stock,  and,  following
the  Distribution  Date,  mail a notice  thereof in  writing  to the  registered
holders of the Right  Certificates.  Failure to give any notice  provided for in
this Section 21, however,  or any defect therein,  shall not affect the legality
or validity of the resignation or removal of the Rights Agent 

<PAGE>
                                                                              68



or the appointment of the successor Rights Agent, as the case may be.

     Section  Issuance  of New Right  Certificates.  Notwithstanding  any of the
provisions of this Agreement or of the Rights to the contrary,  the Company may,
at its option,  issue new Right Certificates  evidencing Rights in such forms as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price and the number or kind or class of shares or other securities
or property purchasable under the Right Certificates made in accordance with the
provisions of this  Agreement.  In addition,  in connection with the issuance or
sale of Common Stock following the Distribution Date and prior to the earlier of
the Redemption Date and the Final  Expiration Date, the Company may with respect
to shares of Common  Stock so issued or sold  pursuant  to (i) the  exercise  of
stock  options,  (ii) under any  employee  plan or  arrangement,  (iii) upon the
exercise,  conversion or exchange of securities,  notes or debentures  issued by
the  Company  or (iv) a  contractual  obligation  of the  Company  in each  case
existing prior to the Distribution Date, issue Rights Certificates  representing
the appropriate number of Rights in connection with such issuance or sale.

     Section Redemption.  The Board of Directors of the Company may, at any time
prior to such time as any Person first becomes an Acquiring  Person,  redeem all
but not less than all the then outstanding  Rights at a redemption price of $.01
per Right,  appropriately adjusted to reflect 

<PAGE>
                                                                              69



any stock split, stock dividend or similar transaction  occurring after the date
hereof (the redemption  price being  hereinafter  referred to as the "Redemption
Price").  The  redemption  of the Rights may be made  effective at such time, on
such  basis  and with such  conditions  as the  Board of  Directors  in its sole
discretion  may  establish.  The Company may, at its option,  pay the Redemption
Price in cash,  shares of Common Stock (based on the current market price of the
Common  Stock at the time of  redemption)  or any  other  form of  consideration
deemed appropriate by the Board of Directors.

     Immediately  upon  the  action  of the  Board  of  Directors  ordering  the
redemption  of the Rights  pursuant to  paragraph  (a) of this Section 23 (or at
such later time as the Board of Directors may establish for the effectiveness of
such  redemption),  and without any further  action and without any notice,  the
right to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the  Redemption  Price.  The Company shall
promptly give public notice of any such redemption;  provided, however, that the
failure to give, or any defect in, any such notice shall not affect the validity
of such  redemption.  Within 10 days after such action of the Board of Directors
ordering  the  redemption  of the  Rights  (or such  later  time as the Board of
Directors may establish for the effectiveness of such  redemption),  the Company
shall mail a notice of  redemption  to all the  holders of the then  outstanding
Rights at their last  addresses  as they appear upon the  registry  books of the
Rights Agent or, prior to the  

<PAGE>
                                                                              70



Distribution  Date, on the registry  books of the transfer  agent for the Common
Stock.  Any notice which is mailed in the manner herein provided shall be deemed
given,  whether or not the  holder  receives  the  notice.  Each such  notice of
redemption  shall state the method by which the payment of the Redemption  Price
will be made.

     Section Exchange. The Board of Directors of the Company may, at its option,
at any time after any Person first becomes an Acquiring Person,  exchange all or
part of the then  outstanding  and  exercisable  Rights (which shall not include
Rights that have not become  effective or that have become void  pursuant to the
provisions  of  Section  11(a)(ii)  hereof)  for  shares of  Common  Stock at an
exchange ratio of one share of Common Stock per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar  transaction  occurring after
the date  hereof  (such  amount per Right being  hereinafter  referred to as the
"Exchange Ratio").  Notwithstanding the foregoing,  the Board of Directors shall
not be empowered to effect such exchange at any time (1) after any Person (other
than an Exempt  Person),  together with all  Affiliates  and  Associates of such
Person,  becomes the Beneficial Owner of shares of Common Stock  aggregating 50%
or more of the  shares  of Common  Stock  then  outstanding.  From and after the
occurrence  of an event  specified  in Section  13(a)  hereof,  any Rights  that
theretofore  have  not been  exchanged  pursuant  to this  

<PAGE>
                                                                              71



Section 24(a) shall thereafter be exercisable only in accordance with Section 13
and may not be  exchanged  pursuant to this Section  24(a).  The exchange of the
Rights by the Board of Directors  may be made  effective  at such time,  on such
basis and with such  conditions as the Board of Directors in its sole discretion
may establish.

     Immediately upon the  effectiveness of the action of the Board of Directors
of the Company  ordering the exchange of any Rights pursuant to paragraph (a) of
this Section 24 and without any further action and without any notice, the right
to exercise  such Rights  shall  terminate  and the only right  thereafter  of a
holder of such Rights  shall be to receive that number of shares of Common Stock
equal  to the  number  of such  Rights  held by such  holder  multiplied  by the
Exchange  Ratio.  The Company  shall  promptly  give  public  notice of any such
exchange;  provided,  however,  that the failure to give, or any defect in, such
notice  shall not  affect the  validity  of such  exchange.  The  Company  shall
promptly  mail a notice of any such exchange to all of the holders of the Rights
so exchanged at their last  addresses as they appear upon the registry  books of
the Rights Agent. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of exchange  will state the method by which the exchange of the shares of Common
Stock for Rights will be effected and, in the event of any partial exchange, the
number of Rights which will be exchanged. Any partial exchange shall be effected
pro rata based on the number of Rights (other than Rights which have

become void pursuant to the provisions of Section 11(a)(ii) hereof) held by each
holder of Rights.

     The  Company  may at its option  and,  in the event that there shall not be
sufficient  shares of Common Stock issued but not  outstanding or authorized but
unissued to permit an exchange of Rights as contemplated in accordance with this
Section 24, the Company shall  substitute  to the extent of such  insufficiency,
for each share of Common Stock that would otherwise be issuable upon exchange of
a Right,  a  number  of  shares  of  Preferred  Stock or  fraction  thereof  (or
equivalent  preferred shares as such term is defined in Section 11(b)) such that
the current per share market price (determined pursuant to Section 11(d) hereof)
of one share of Preferred Stock (or equivalent  preferred  share)  multiplied by
such number or fraction  is equal to the current per share  market  price of one
share of Common Stock  (determined  pursuant to Section  11(d) hereof) as of the
date of such exchange).

     Section  Notice of Certain  Events.  In case the Company  shall at any time
after the earlier of the Distribution Date or the Stock Acquisition Date propose
(i) to pay any  dividend  payable  in stock of any class to the  holders  of its
Preferred  Stock  or to  make  any  other  distribution  to the  holders  of its
Preferred Stock (other than a regular quarterly cash dividend), (ii) to offer to
the holders of its  Preferred  Stock rights or warrants to  subscribe  for or to
purchase  any  additional  shares of  Preferred  Stock or shares of stock of any
class  or  any  other

Preferred Stock (other than a reclassification involving only the subdivision or
combination of outstanding  Preferred  Stock),  (iv) to effect the  liquidation,
dissolution or winding up of the Company,  or (v) to declare or pay any dividend
on the  Common  Stock  payable  in  Common  Stock or to  effect  a  subdivision,
combination  or  consolidation  of the  Common  Stock  (by  reclassification  or
otherwise  than by payment of dividends  in Common  Stock),  then,  in each such
case,  the  Company  shall  give  to each  holder  of a  Right  Certificate,  in
accordance with Section 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, or distribution
of rights or warrants,  or the date on which such  liquidation,  dissolution  or
winding up is to take place and the date of participation therein by the holders
of the Common Stock and/or Preferred Stock, if any such date is to be fixed, and
such notice shall be so given in the case of any action covered by clause (i) or
(ii) above at least 10 days prior to the record date for determining  holders of
the  Preferred  Stock for purposes of such  action,  and in the case of any such
other action,  at least 10 days prior to the date of the taking of such proposed
action or the date of  participation  therein by the holders of the Common Stock
and/or Preferred Stock, whichever shall be the earlier.

     In case any event described in Section  11(a)(ii) or Section 13 shall occur
then the Company shall as soon as

practicable  thereafter  give  to each  holder  of a  Right  Certificate  (or if
occurring  prior to the  Distribution  Date, the holders of the Common Stock) in
accordance  with Section 26 hereof,  a notice of the  occurrence  of such event,
which notice shall  describe  such event and the  consequences  of such event to
holders of Rights under Section 11(a)(ii) and Section 13 hereof.

directs,  supplement  or amend any  provision  of this  Agreement in any respect

construed to give to any Person other than the Company, the Rights Agent and the

                             IMS Health Incorporated

                         (Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware)

                                   ----------



     IMS Health  Incorporated,  a corporation  organized and existing  under the
General  Corporation  Law of the  State  of  Delaware  (hereinafter  called  the
"Company"),  hereby certifies that the following  resolution was duly adopted by
the Board of  Directors of the Company as required by Section 151 of the General
Corporation  Law of the State of Delaware  at a meeting  duly called and held on
June 15, 1998.

     RESOLVED, that pursuant to the authority granted to and vested in the Board
of Directors of the Company  (hereinafter called the "Board of Directors" or the
"Board") in  accordance  with the  provisions of the  Company's  Certificate  of
Incorporation,  as  amended to date  (hereinafter  called  the  "Certificate  of
Incorporation"),  the Board of  Directors  hereby  creates a series of Preferred
Stock,  par  value  $.01  per  share,  of the  Company  and  hereby  states  the
designation  and number of shares,  and fixes the  relative  rights,  powers and
preferences thereof, and the limitations thereof, as follows:

     Section  Designation  and  Amount.  The  shares  of such  series  shall  be
designated  as "Series A Junior  Participating  Preferred  Stock" (the "Series A
Preferred  Stock") and the number of shares  constituting the Series A Preferred
Stock shall be 500,000.  Such number of shares may be  increased or decreased by
resolution of the Board of Directors;  provided,  that no decrease  shall reduce
the  number  of shares of  Series A  Preferred  Stock to a number  less than the
number of shares  then  outstanding  plus the  number  of  shares  reserved  for
issuance upon the exercise of  outstanding  options,  rights or warrants or upon
the conversion of any outstanding  securities issued by the Company  convertible
into Series A Preferred Stock.


                                      A-1

     Section Dividends and Distributions.

     Subject  to the  rights  of the  holders  of any  shares  of any  series of
Preferred  Stock of the Company (the  "Preferred  Stock") (or any similar stock)
ranking  prior and  superior  to the Series A  Preferred  Stock with  respect to
dividends,  the holders of shares of Series A Preferred  Stock, in preference to
the  holders of Common  Stock,  par value $.01 per share,  of the  Company  (the
"Common  Stock")  and of any other stock of the  Company  ranking  junior to the
Series A Preferred Stock, shall be entitled to receive, when, as and if declared
by the  Board of  Directors  out of funds  legally  available  for the  purpose,
quarterly dividends payable in cash on the last day of January, April, July, and
October in each year (each such date  being  referred  to herein as a  "Dividend
Payment  Date"),  commencing on the first Dividend  Payment Date after the first
issuance of a share or fraction  of a share of Series A Preferred  Stock,  in an
amount per share  (rounded to the nearest  cent) equal to the greater of (a) $10
or (b) subject to the provision for adjustment hereinafter set forth, 1000 times
the  aggregate  per  share  amount  of all cash  dividends,  and 1000  times the
aggregate per share amount (payable in kind) of all non-cash  dividends or other
distributions other than a dividend payable in shares of Common Stock,  declared
on the Common Stock since the immediately  preceding  Dividend  Payment Date or,
with respect to the first Dividend Payment Date, since the first issuance of any
share or  fraction  of a share of  Series A  Preferred  Stock.  In the event the
Company shall at any time after June 15, 1998 declare or pay any dividend on the
Common  Stock  payable in shares of Common  Stock,  or effect a  subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case the amount to which holders of shares of Series A Preferred Stock were
entitled  immediately  prior to such event  under  clause  (b) of the  preceding
sentence  shall be  adjusted  by  multiplying  such  amount by a  fraction,  the
numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

     The  Company  shall  declare a  dividend  or  distribution  on the Series A
Preferred Stock as provided in paragraph (A) of this Section  immediately  after
it  declares a  dividend  or  distribution  on the Common  Stock  (other  than a
dividend  payable in shares of Common  Stock);  provided  that,  in the event no
dividend or distribution shall have been declared on the Common Stock during the
period  between  any  Dividend  Payment  Date and the next  subsequent  Dividend
Payment Date, a dividend of $10 per share on the Series A Preferred  Stock shall
nevertheless be payable,  when, as and if declared,  on such subsequent Dividend
Payment Date.


                                      A-2
<PAGE>


     Dividends shall begin to accrue and be cumulative, whether or not earned or
declared,  on outstanding  shares of Series A Preferred  Stock from the Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such shares is prior to the record date for the first Dividend  Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares,  or unless the date of issue is a Dividend Payment Date
or is a date after the record date for the determination of holders of shares of
Series A Preferred  Stock  entitled to receive a quarterly  dividend  and before
such Dividend Payment Date, in either of which events such dividends shall begin
to accrue and be cumulative from such Dividend Payment Date.  Accrued but unpaid
dividends  shall not bear  interest.  Dividends  paid on the  shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at the
time  accrued  and  payable  on such  shares  shall be  allocated  pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Directors  may fix a record date for the  determination  of holders of shares of
Series  A  Preferred  Stock  entitled  to  receive  payment  of  a  dividend  or
distribution declared thereon,  which record date shall be not more than 60 days
prior to the date fixed for the payment thereof.

     Section  Voting Rights.  The holders of shares of Series A Preferred  Stock
shall have the following voting rights;

     Subject to the provision for adjustment hereinafter set forth and except as
otherwise  provided in the Certificate of Incorporation or required by law, each
share of Series A Preferred Stock shall entitle the holder thereof to 1000 votes
on all  matters  upon which the  holders of the Common  Stock of the Company are
entitled to vote. In the event the Company shall at any time after June 15, 1998
declare  or pay any  dividend  on the Common  Stock  payable in shares of Common
Stock,  or  effect  a  subdivision  or  combination  or   consolidation  of  the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock,  then in each such case the number of votes per share
to which holders of shares of Series A Preferred Stock were entitled immediately
prior to such event shall be adjusted by multiplying  such number by a fraction,
the  numerator  of which is the  number of shares  of Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

     Except as otherwise provided herein, in the Certificate of Incorporation or
in any other Certificate of Designations creating a series of Preferred Stock or
any


                                      A-3
<PAGE>


similar stock, and except as otherwise required by law, the holders of shares of
Series A Preferred Stock and the holders of shares of Common Stock and any other
capital stock of the Company having general voting rights shall vote together as
one class on all matters submitted to a vote of stockholders of the Company.

     Except as set forth  herein,  or as otherwise  provided by law,  holders of
Series A Preferred  Stock shall have no special  voting rights and their consent
shall not be  required  (except to the  extent  they are  entitled  to vote with
holders of Common Stock as set forth herein) for taking any corporate action.

     Section Certain Restrictions.

     Whenever quarterly dividends or other dividends or distributions payable on
the Series A Preferred Stock as provided in Section 2 are in arrears, thereafter
and until all accrued and unpaid  dividends  and  distributions,  whether or not
earned or declared, on shares of Series A Preferred Stock outstanding shall have
been paid in full, the Company shall not:

     declare or pay dividends, or make any other distributions, on any shares of
stock ranking junior (as to dividends) to the Series A Preferred Stock;

     declare or pay dividends, or make any other distributions, on any shares of
stock ranking on a parity (as to dividends)  with the Series A Preferred  Stock,
except  dividends  paid  ratably  on the Series A  Preferred  Stock and all such
parity stock on which  dividends  are payable or in arrears in proportion to the
total amounts to which the holders of all such shares are then entitled;

     redeem or purchase or  otherwise  acquire for  consideration  shares of any
stock ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Preferred  Stock,  provided  that the Company may at
any time redeem,  purchase or otherwise  acquire shares of any such junior stock
in  exchange  for  shares  of any stock of the  Company  ranking  junior  (as to
dividends  and upon  dissolution,  liquidation  or  winding  up) to the Series A
Preferred Stock or rights, warrants or options to acquire such junior stock;

     redeem or purchase or  otherwise  acquire for  consideration  any shares of
Series A Preferred  Stock, or any shares of stock ranking on a parity (either as
to dividends or upon  liquidation,  dissolution or winding up) with the Series A
Preferred  Stock,  except in accordance with a purchase offer made in writing or
by publication  (as determined by the Board of Directors) to all holders of such
shares upon such terms as the Board of  Directors,  after  consideration  of the
respective annual dividend rates and


                                      A-4
<PAGE>


other relative  rights and  preferences  of the  respective  series and classes,
shall determine in good faith will result in fair and equitable  treatment among
the respective series or classes.

     The Company  shall not permit any  subsidiary of the Company to purchase or
otherwise  acquire for  consideration  any shares of stock of the Company unless
the Company could,  under paragraph (A) of this Section 4, purchase or otherwise
acquire such shares at such time and in such manner.

     Section Reacquired Shares. Any shares of Series A Preferred Stock purchased
or otherwise  acquired by the Company in any manner  whatsoever shall be retired
and cancelled promptly after the acquisition thereof. All such shares shall upon
their  retirement  become  authorized but unissued shares of Preferred Stock and
may be  reissued  as part of a new  series of  Preferred  Stock to be created by
resolution or resolutions  of the Board of Directors,  subject to any conditions
and restrictions on issuance set forth herein.

     Section  Liquidation,  Dissolution  or Winding  Up.  Upon any  liquidation,
dissolution or winding up of the Company,  no distribution  shall be made (A) to
the  holders of the Common  Stock or of shares of any other stock of the Company
ranking  junior,  upon  liquidation,  dissolution or winding up, to the Series A
Preferred  Stock  unless,  prior  thereto,  the  holders  of  shares of Series A
Preferred  Stock shall have  received  $100 per share,  plus an amount  equal to
accrued and unpaid dividends and distributions thereon, whether or not earned or
declared,  to the date of such  payment,  provided that the holders of shares of
Series A Preferred  Stock shall be entitled to receive an  aggregate  amount per
share,  subject to the provision for adjustment  hereinafter set forth, equal to
1000 times the aggregate amount to be distributed per share to holders of shares
of Common  Stock,  or (B) to the holders of shares of stock  ranking on a parity
upon  liquidation,  dissolution or winding up with the Series A Preferred Stock,
except  distributions  made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled  upon such  liquidation,  dissolution  or winding up. In the
event, however, that there are not sufficient assets available to permit payment
in full of the Series A liquidation  preference and the liquidation  preferences
of all other classes and series of stock of the Company,  if any, that rank on a
parity with the Series A  Preferred  Stock in respect  thereof,  then the assets
available for such distribution  shall be distributed  ratably to the holders of
the  Series A  Preferred  Stock and the  holders  of such  parity  shares in the
proportion to their respective liquidation preferences. In the event the Company
shall at any time after June 15, 1998 declare or pay any dividend on the



                                      A-5
<PAGE>


Common  Stock  payable in shares of Common  Stock,  or effect a  subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case the aggregate  amount to which holders of shares of Series A Preferred
Stock were entitled  immediately prior to such event under the proviso in clause
(A) of the preceding  sentence shall be adjusted by multiplying such amount by a
fraction  the  numerator  of which is the  number  of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     Section  Consolidation,  Merger,  etc. In case the Company shall enter into
any consolidation,  merger, combination or other transaction in which the shares
of Common Stock are converted into, exchanged for or changed into other stock or
securities,  cash and/or any other property, then in any such case each share of
Series A Preferred  Stock shall at the same time be  similarly  converted  into,
exchanged for or changed into an amount per share  (subject to the provision for
adjustment  hereinafter  set forth) equal to 1000 times the aggregate  amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be,  into  which or for  which  each  share of  Common  Stock is  converted,
exchanged or  converted.  In the event the Company  shall at any time after June
15, 1998 declare or pay any  dividend on the Common  Stock  payable in shares of
Common Stock,  or effect a subdivision or combination  or  consolidation  of the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common  Stock,  then in each such case the  amount set forth in the
preceding sentence with respect to the conversion,  exchange or change of shares
of Series A Preferred  Stock shall be adjusted by  multiplying  such amount by a
fraction,  the  numerator  of which is the  number of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     Section No Redemption.  The shares of Series A Preferred Stock shall not be
redeemable from any holder.

     Section Rank. The Series A Preferred  Stock shall rank, with respect to the
payment  of  dividends  and  the   distribution  of  assets  upon   liquidation,
dissolution  or  winding  up of the  Company,  junior  to all  other  series  of
Preferred Stock and senior to the Common Stock.

     Section  Amendment.  If  any  proposed  amendment  to  the  Certificate  of
Incorporation (including


                                      A-6
<PAGE>


this  Certificate  of  Designations)  would  alter,  change or repeal any of the
preferences,  powers or special rights given to the Series A Preferred  Stock so
as to affect the Series A  Preferred  Stock  adversely,  then the holders of the
Series A Preferred  Stock shall be entitled to vote  separately  as a class upon
such amendment, and the affirmative vote of two-thirds of the outstanding shares
of the  Series  A  Preferred  Stock,  voting  separately  as a  class,  shall be
necessary  for the  adoption  thereof,  in addition to such other vote as may be
required by the General Corporation Law of the State of Delaware.

     Section  Fractional  Shares.  Series A  Preferred  Stock  may be  issued in
fractions  of a share that shall  entitle  the  holder,  in  proportion  to such
holder's  fractional  shares,  to exercise  voting  rights,  receive  dividends,
participate  in  distributions  and to have the  benefit of all other  rights of
holders of Series A Preferred Stock.

     UNDER CERTAIN CIRCUMSTANCES,  AS SET FORTH IN THE RIGHTS AGREEMENT,  RIGHTS
     OWNED BY OR TRANSFERRED  TO ANY PERSON WHO BECOMES AN ACQUIRING  PERSON (AS
     DEFINED IN THE RIGHTS  AGREEMENT)  AND  CERTAIN  TRANSFEREES  THEREOF  WILL
     BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                          SUMMARY OF RIGHTS TO PURCHASE
                            Shares of Preferred Stock

     On June 15, 1998 the Board of  Directors  of IMS Health  Incorporated  (the
"Company") declared a dividend of one preferred share purchase right (a "Right")
for each  outstanding  share of common  stock,  par value  $.01 per share of the
Company  (the  "Common  Stock").  The  dividend is payable on June 29, 1998 (the
"Record Date") to the  stockholders  of record on that date. Each Right entitles
the registered holder to purchase from the Company one one-thousandth of a share
of Series A Junior Participating  Preferred Stock, par value $.01 per share (the
"Preferred Stock") of the Company at a price of $225 per one one-thousandth of a
share of Preferred  Stock (as the same may be adjusted,  the "Purchase  Price"),
subject to adjustment.  The description and terms of the Rights are set forth in
a Rights  Agreement  dated as of June 15,  1998 as the same may be amended  from
time to time (the  "Rights  Agreement"),  between the Company and First  Chicago
Trust Company of New York as Rights Agent (the "Rights Agent").

     Until the earlier to occur of (i) 10 days  following a public  announcement
that a  person  or group of  affiliated  or  associated  persons  (with  certain
exceptions an "Acquiring Person") have acquired  beneficial  ownership of 15% or
more (20% or more in the case of an "Institutional  Investor" as defined) of the
outstanding  shares of Common Stock or (ii) 10 business days (or such later date
as may be determined  by action of the Board of Directors  prior to such time as
any person or group of affiliated persons becomes an Acquiring Person) following
the  commencement of, or announcement of an intention to make, a tender offer or
exchange  offer  the  consummation  of  which  would  result  in the  beneficial
ownership  by a  person  or group of 15% or more of the  outstanding  shares  of
Common Stock (the earlier of such dates being called the  "Distribution  Date"),
the Rights will be evidenced by such Common Stock  certificate  together  with a
copy of this Summary of Rights.

     The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights), the Rights will be transferred with and
only with the Common Stock.  Until the Distribution Date


                                       1
<PAGE>


(or earlier  redemption or expiration of the Rights),  Common Stock certificates
will contain a notation  incorporating the Rights Agreement by reference.  Until
the Distribution Date (or earlier  redemption or expiration of the Rights),  the
surrender  for  transfer  of  any   certificates  for  shares  of  Common  Stock
outstanding as of the Record Date,  even without such notation or a copy of this
Summary of Rights,  will also  constitute the transfer of the Rights  associated
with the shares of Common  Stock  represented  by such  certificate.  As soon as
practicable  following the Distribution Date, separate  certificates  evidencing
the  Rights  ("Right  Certificates")  will be mailed to holders of record of the
Common  Stock as of the  close of  business  on the  Distribution  Date and such
separate Right Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire  on June 30,  2008  (the  "Final  Expiration  Date"),  unless  the  Final
Expiration  Date is  advanced  or  extended  or unless the  Rights  are  earlier
redeemed or exchanged by the Company, in each case as described below.

     The Purchase Price payable,  and the number of shares of Preferred Stock or
other securities or property  issuable,  upon exercise of the Rights are subject
to adjustment from time to time to prevent  dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock,  (ii) upon the grant to holders of the Preferred  Stock of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Stock at a  price,  or
securities  convertible into Preferred Stock with a conversion  price, less than
the  then-current  market  price  of the  Preferred  Stock  or  (iii)  upon  the
distribution  to holders of the Preferred  Stock of evidences of indebtedness or
assets  (excluding  regular  periodic  cash  dividends or  dividends  payable in
Preferred  Stock)  or of  subscription  rights or  warrants  (other  than  those
referred to above).

     The Rights are also subject to adjustment in the event of a stock  dividend
on the  Common  Stock  payable  in  shares  of  Common  Stock  or  subdivisions,
consolidations or combinations of the Common Stock occurring,  in any such case,
prior to the Distribution Date.

     Shares of Preferred Stock  purchasable upon exercise of the Rights will not
be redeemable.  Each share of Preferred Stock will be entitled,  when, as and if
declared, to a minimum preferential  quarterly dividend payment of $10 per share
but will be  entitled  to an  aggregate  dividend  of 1000  times  the  dividend
declared per share of Common Stock. In the event of liquidation,  dissolution or
winding up of the Company,  the holders of the Preferred  Stock will be entitled
to a  minimum  preferential  liquidation  payment  of $100 per  share  (plus any
accrued but unpaid  dividends)  but will be entitled to an aggregate  payment of
1000 times the payment made per share of Common  Stock.  Each share of Preferred
Stock will have 1000 votes,  voting together with the Common Stock.  Finally, in
the


                                       2
<PAGE>


event of any  merger,  consolidation  or other  transaction  in which  shares of
Common Stock are converted or exchanged,  each share of Preferred  Stock will be
entitled to receive 1000 times the amount  received  per share of Common  Stock.
These rights are protected by customary antidilution provisions.

     Because of the nature of the Preferred  Stock's  dividend,  liquidation and
voting  rights,  the  value  of the one  one-thousandth  interest  in a share of
Preferred Stock  purchasable upon exercise of each Right should  approximate the
value of one share of Common Stock.

     In the event that any person or group of affiliated  or associated  persons
becomes  an  Acquiring  Person,  each  holder  of a  Right,  other  than  Rights
beneficially  owned by the Acquiring  Person (which will thereupon become void),
will  thereafter  have the right to receive upon exercise of a Right and payment
of the  Purchase  Price,  that number of shares of Common  Stock having a market
value of two times the Purchase Price.

     In the event that, after a person or group has become an Acquiring  Person,
the Company is acquired in a merger or other business combination transaction or
50% or more of its  consolidated  assets  or  earning  power  are  sold,  proper
provision  will be made  so that  each  holder  of a Right  (other  than  Rights
beneficially  owned by an  Acquiring  Person  which will have become  void) will
thereafter  have the right to  receive,  upon the  exercise  thereof at the then
current  exercise  price of the Right,  that number of shares of common stock of
the person with whom the Company has engaged in the  foregoing  transaction  (or
its parent),  which number of shares at the time of such transaction will have a
market value of two times the Purchase Price.

     At any time after any person or group becomes an Acquiring Person and prior
to the  acquisition  by such  person or group of 50% or more of the  outstanding
shares of Common  Stock or the  occurrence  of an event  described  in the prior
paragraph,  the Board of Directors of the Company may exchange the Rights (other
than Rights owned by such person or group which will have become void), in whole
or in part, at an exchange  ratio of one share of Common Stock,  or a fractional
share of  Preferred  Stock  (or of a share of a  similar  class or series of the
Company's preferred stock having similar rights,  preferences and privileges) of
equivalent value, per Right (subject to adjustment).

     With  certain  exceptions,  no  adjustment  in the  Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such  Purchase  Price.  No fractional  shares of Preferred  Stock will be issued
(other than fractions which are integral  multiples of one  one-thousandth  of a
share of  Preferred  Stock,  which  may,  at the  election  of the  Company,  be
evidenced by depositary  


                                       3
<PAGE>


receipts) and in lieu  thereof,  an adjustment in cash will be made based on the
market price of the Preferred Stock on the last trading day prior to the date of
exercise.

     At any time prior to the time an Acquiring  Person  becomes such, the Board
of Directors of the Company may redeem the Rights in whole,  but not in part, at
a price of $.01 per Right (the "Redemption Price"). The redemption of the Rights
may be made  effective at such time,  on such basis and with such  conditions as
the Board of Directors in its sole  discretion may establish.  Immediately  upon
any  redemption of the Rights,  the right to exercise the Rights will  terminate
and the only right of the holders of Rights  will be to receive  the  Redemption
Price.

     For so long as the Rights are then redeemable, the Company may, except with
respect  to the  redemption  price,  amend the Rights in any  manner.  After the
Rights are no longer  redeemable,  the Company  may,  except with respect to the
redemption price,  amend the Rights in any manner that does not adversely affect
the interests of holders of the Rights.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.

     A copy of the  Rights  Agreement  has been filed  with the  Securities  and
Exchange Commission as an Exhibit to a Registration  Statement on Form 8-A dated
June 23, 1998. A copy of the Rights  Agreement is available  free of charge from
the  Company.  This  summary  description  of the Rights  does not purport to be
complete and is qualified in its entirety by reference to the Rights  Agreement,
as the same may be  amended  from  time to time,  which is  hereby  incorporated
herein by reference.

                             IMS HEALTH INCORPORATED
                            SAVINGS EQUALIZATION PLAN


I.     Purpose of the Plan

       The purpose of the IMS Health Incorporated Savings Equalization Plan (the
"Plan") is to provide a means of  equalizing  the  benefits  of those  employees
participating  in the IMS Health  Incorporated  Savings Plan (the "401(k) Plan")
whose matching contributions under the 401(k) Plan are or will be limited by the
application of sections  401(a)(17) or 415 of the Internal Revenue Code of 1986,
as amended (the "Code").  The Plan is intended to be an "excess benefit plan" as
that term is defined in section 3(36) of the Employee Retirement Income Security
Act of 1974,  as amended  ("ERISA")  with  respect to those  participants  whose
benefits under the 401(k) Plan have been limited by Section 415 of the Code, and
a plan which is unfunded  and is  maintained  by an employer  primarily  for the
purposes of providing deferred  compensation for a select group of management or
highly compensated employees for purposes of ERISA.

II.    Administration of the Plan

       The Compensation Committee of the Board of Directors (the "Committee") of
IMS Health  Incorporated  (the  "Corporation" or the "Company") shall administer
the Plan and may  delegate  to any  committee,  employee,  director or agent its
responsibility to perform any act hereunder,  including without limitation those
matters  involving the exercise of  discretion,  provided  that such  delegation
shall be subject to  revocation  at any time at its  discretion.  The  Committee
shall have full authority to determine all questions  arising in connection with
the Plan, other than those determinations  delegated to employees or independent
third parties by the Board of Directors,  including  interpreting its provisions
and construing all of its terms; may adopt procedural  rules; and may employ and
rely on such legal counsel, such actuaries,  such accountants and such agents as
it may deem  advisable to assist in the  administration  of the Plan. All of its
rules, interpretations and decisions shall be applied in a uniform manner to all
participants  similarly  situated  and  decisions  of  the  Committee  shall  be
conclusive and binding on all persons.

III.   Participation in the Plan

       All members of the 401(k) Plan shall be eligible to  participate  in this
Plan  whenever  their  benefits  under the  401(k)  Plan as from time to time in
effect would exceed the  limitations  on benefits and  contributions  imposed by
sections 401(a)(17) or 415 of the Code. For purposes of this Plan, benefits of a
participant  in this  Plan  shall be  determined  as though  no  provision  were
contained  in the 401(k)  Plan  incorporating  limitations  imposed by  Sections
401(a)(17) or 415 of the Code.


<PAGE>



IV.    Equalized Benefits

       If member  participating  contributions  or Company  contributions to the
401(k)  Plan  are   suspended   during  any  calendar   year  because  any  such
contributions  would cause the  participant's  account under such plan to exceed
the benefit limitations related to such plan as described in Section III of this
Plan, the Corporation  shall pay the  participant,  on or about March 1st of the
following year, an amount equal to:

              (1) the Company matching  contributions  that otherwise would have
       been credited to such to such participant's account under the 401(k) Plan
       for the  balance of the year in which such  suspension  occurs,  as if no
       provision  were set forth therein  incorporating  limitations  imposed by
       section  401(a)(17) or 415 of the Code, and the participant had continued
       his  elective  deferrals  to the 401(k) Plan at the rate in effect at the
       time such  contributions  were  suspended  for the balance of the year in
       which such suspension occurs, plus

              (2) an interest  factor  equal to  one-half  of the annual  return
       which would have been received by the  participant  had such payment been
       invested  eighty  percent (80%) in the Special Fixed Income Fund (Fund C)
       of the 401(k) Plan and twenty  percent (20%) in the BZW Equity Index Fund
       (Fund A) of the 401(k) plan during the year which such suspension occurs,
       less

              (3) any applicable withholding taxes.

V.     Miscellaneous

       This Plan may be  terminated at any time by the Board of Directors of the
Corporation, in which event the rights of participants to their accrued benefits
shall  become  nonforfeitable.  This Plan may also be amended at any time by the
Board of  Directors  of the  Corporation,  except that no such  amendment  shall
deprive any participant of benefits accrued at the time of such amendment.

       Benefits  payable  under  this Plan shall not be funded and shall be made
out of the  general  funds  of the  Corporation;  provided,  however,  that  the
Corporation  reserves the right to establish a trust fund as an alternate source
of benefits payable under the Plan and to the extent payments are made from such
trust, such payments will satisfy he Corporation's obligations under this Plan.

       No  right  to  payment  or any  other  interest  under  this  Plan may be
alienated, sold, transferred,  pledged, assigned, or made subject to attachment,
execution, or levy of any kind.


<PAGE>



       Nothing in this Plan shall be  construed as giving any employee the right
to be  retained  in the employ of the  Corporation.  The  Corporation  expressly
reserves  the right to dismiss any  employee at any time  without  regard to the
effect which such dismissal might have upon him under the Plan.

       This Plan shall be construed,  administered and enforced according to the
laws of the State of Connecticut unless preempted by federal law.

VI.    Effective Date

       This Plan  shall be  effective  as of the date on which  shares of common
stock of the Company that are owned by Cognizant  Corporation  ("Cognizant") are
distributed to the holders of record of shares of Cognizant.

- - --------------------------------------------------------------------------------



       THIS  EMPLOYMENT  AGREEMENT  by and  between IMS HEALTH  INCORPORATED,  a
Delaware corporation (the "Company"), and Robert E. Weissman ("Executive") shall
become effective as of July 1, 1998 (the "Effective Date").

                                   WITNESSETH

       WHEREAS,  Executive  has served the Company and its  predecessors  in the
position of Chairman of the Board and Chief Executive  Officer since April 1995,
and in senior executive capacities since January 1985;

       WHEREAS,  the Company desires to continue to employ Executive as Chairman
of the Board and Chief Executive  Officer of the Company,  and Executive desires
to accept such employment on the terms and conditions herein set forth.

       NOW, THEREFORE,  in consideration of the foregoing,  the mutual covenants
contained  herein,  and other good and  valuable  consideration  the receipt and
adequacy of which the Company and Executive each hereby acknowledge, the Company
and Executive hereby agree as follows:

       1.     Employment.

       The Company  hereby  agrees to employ  Executive  as its  Chairman of the
Board and Chief Executive  Officer,  and Executive  hereby agrees to accept such
employment and serve in such capacities, during the Term as defined in Section 2
(subject to Section 7(c) and

<PAGE>

7(e)) and upon the terms and conditions set forth in this  Employment  Agreement
(the "Agreement").

       2.     Term.

       The term of employment  of Executive  under this  Agreement  (the "Term")
shall be the period commencing on the Effective Date and ending on June 30, 2001
and any period of extension  thereof in  accordance  with this Section 2, except
that the Term will end at a date,  prior to the end of such period or  extension
thereof,  specified in Section 6 or 7 in the event of termination of Executive's
employment.  The Term, if not previously ended, shall be extended  automatically
without  further action by either party by one additional year (added to the end
of the Term) first on June 30, 2001 (extending the Term to June 30, 2002) and on
each  succeeding  June 30  thereafter,  unless  either  party  shall have served
written  notice in  accordance  with  Section  12(d) upon the other  party on or
before the December 31 preceding a June 30 extension date electing not to extend
the Term further as of that June 30  extension  date,  in which case  employment

following such Potential Change in Control.

       3.     Offices and Duties.

       The  provisions  of this Section 3 will apply during the Term,  except as
otherwise provided in Section 7(c) and 7(e):

committee if the Board shall elect Executive to such  committee.  In any and all
such  capacities,  Executive  shall report only to the Board of Directors of the
Company.  Executive  shall have and perform such duties,  responsibilities,  and
authorities  as are customary for the chairman of the board and chief  executive
officer of a publicly  held  corporation  of the size,  type,  and nature of the
Company as they may exist from time to time and  consistent  with such  position

be reduced from those of Executive at the Effective Date. Executive shall devote
his  full  business  time  and  attention,  and  his  best  efforts,  abilities,
experience,  and  talent,  to the  positions  of Chairman of the Board and Chief
Executive  Officer and for the businesses of the Company  without  commitment to

as such  activities  (i.e.,  those  listed in clauses (i)  through  (iv)) do not

otherwise  materially  inhibit the performance of Executive's  duties under this
Agreement or materially impair the business of the Company or its subsidiaries.

       As partial  compensation  for the  services to be rendered  hereunder  by
Executive,  the  Company  agrees  to  pay  to  Executive  during  the  Term  the
compensation set forth in this Section 4.

       (a) Base Salary. The Company will pay to Executive during the Term a base
salary at the initial annual rate of $775,000,  payable in cash in substantially
equal  semi-monthly  installments  commencing at the beginning of the Term,  and
otherwise in accordance with the Company's usual payroll  practices with respect
to senior  executives  (except  to the  extent  deferred  under  Section  5(d)).
Executive's  annual  base  salary  shall be  reviewed  by the  Compensation  and
Benefits Committee of the Board (the "Committee") at least once in each calendar
year and may be increased  above, but may not be reduced below, the then-current
rate of such base salary.  For purposes of this  Agreement,  "Base Salary" means
Executive's then-current base salary.

       (b) Annual  Incentive  Compensation.  The Company  will pay to  Executive
during the Term annual incentive  compensation which shall offer to Executive an
opportunity to earn additional  compensation  based upon  performance in amounts
determined  by  the  Committee  in  accordance  with  the  applicable  plan  and
consistent  with past  practices of the  Company;  provided,  however,  that the
annual target incentive  opportunity  shall be not less than the greater of 100%
of Base Salary or the annual target incentive opportunity for the prior year for
achievement of target level performance,  with the nature of the performance and
the levels of performance  triggering  payments of such annual target  incentive
compensation  for each year to be  established  and  communicated  to  Executive

Committee  (or the Board) may  determine,  in its  discretion,  to increase  the
Executive's annual target incentive  opportunity or provide an additional annual
incentive  opportunity,  in excess of the annual target  incentive  opportunity,
payable for performance in excess of or in addition to the performance  required
for  payment  of the  annual  target  incentive  amount.  Any  annual  incentive
compensation payable to Executive shall be paid in accordance with the Company's
usual practices with respect to payment of incentive

                                      -3-

       5.     Long-Term Compensation, Including Stock Options, and Benefits,
              Deferred Compensation, and Expense Reimbursement

       (a) Executive  Compensation Plans. Executive shall be entitled during the
Term to participate,  without  discrimination  or duplication,  in all executive
compensation  plans and programs  intended for general  participation  by senior
executives of the Company,  as presently in effect or as they may be modified or
added to by the Company from time to time,  subject to the eligibility and other
requirements of such plans and programs,  including without limitation any stock
option  plans,  plans  under  which  restricted  stock/restricted  stock  units,
performance-based   restricted   stock/restricted   stock   units   ("PERS")  or
performance-accelerated  restricted stock/restricted stock units ("PARS") may be
awarded,  other annual and long-term  cash and/or equity  incentive  plans,  and
deferred compensation plans; provided, however, that such plans and programs, in
the aggregate,  shall provide  Executive with  compensation  and incentive award
opportunities substantially no less favorable than those provided by the Company
to Executive under such plans and programs as in effect on the Effective Date.

       (b) Employee and Executive  Benefit  Plans.  Executive  shall be entitled
during the Term to participate,  without  discrimination or duplication,  in all
employee and executive  benefit plans and programs of the Company,  as presently
in effect or as they may be  modified  or added to by the  Company  from time to
time,  to the extent such plans are  available  to other  senior  executives  or
employees of the Company,  subject to the eligibility and other  requirements of
such plans and programs,  including without limitation plans providing pensions,
supplemental  pensions,  supplemental  and other  retirement  benefits,  medical
insurance,  life  insurance,  disability  insurance,  and  accidental  death  or
dismemberment insurance, as well as savings, profit-sharing, and stock ownership
plans;  provided,  however,  that  such  benefit  plans  and  programs,  in  the
aggregate,  shall provide Executive with benefits and compensation substantially
no less  favorable  than those  provided by the Company to Executive  under such
plans  and  programs  as  in  effect  on  the  Effective   Date.  The  foregoing
notwithstanding,  Executive  shall not be  eligible  to  participate  or receive
benefits under the Company's Employee Protection Plan.

       In  furtherance  of and not in  limitation of the  foregoing,  during the
Term:

       (i)    Executive  will  participate  as Chief  Executive  Officer  in all
              executive and employee vacation and time-off programs;

       (ii)   The  Company  will  provide   Executive  with  coverage  as  Chief
              Executive Officer with respect to long-term  disability  insurance
              and  benefits  substantially  no  less  favorable  (including  any
              required  contributions  by  Executive)  than such  insurance  and
              benefits in effect on the Effective Date;

       (iii)  Executive  will be covered by  Company-paid  group and  individual
              term life  insurance  providing  a death  benefit no less than the

              the Effective Date; provided,

                                      -4-

<PAGE>

              however, that, with the consent of Executive, such insurance may
              be combined with a supplementary retirement funding vehicle;

       (iv)   Executive will be entitled to retirement benefits substantially no
              less favorable than those under the defined  benefit pension plans
              and programs of the Company, including the IMS Health Incorporated
              Supplemental  Executive Retirement Plan (the "SERP"), as in effect
              on the Effective Date; and

       (v)    The  Company  will  provide  Executive  with  health  and  medical
              benefits consistent with its policies for other senior executives.

       Any   provision   to   the   contrary   contained   in   this   Agreement
notwithstanding,  unless  Executive is terminated by the Company for "Cause" (as
defined in Section 8(a)) or Executive  terminates  voluntarily and not for "Good
Reason"  (as  defined  in  Section   8(e)),   Executive   may  elect   continued
participation  after  termination  of  employment  in the  Company's  health and
medical  coverage for himself and his spouse and dependent  children  after such
coverage would otherwise end until such time as Executive  becomes  eligible for
similar  coverage with a subsequent  employer or other entity to which Executive
provides services or becomes eligible for Medicare (under rules in effect at the
Effective Date hereof);  provided,  however, that in the event of such election,
Executive  shall pay the Company each year an amount  equal to the  then-current
annual COBRA premium being paid (or payable) by any other former employee of the
Company, unless otherwise provided under Section 6 or 7.

       (c)  Acceleration  of Awards Upon a Change in Control.  In the event of a
Change in Control (as defined in Section 8(b)),  all  outstanding  stock options
and restricted stock then held by Executive shall become vested and exercisable.

       (d) Deferral of Compensation.  If the Company has in effect or adopts any
deferral  program or  arrangement  permitting  executives  to elect to defer any
compensation, Executive will be eligible to participate in such program on terms
no less favorable than the terms of participation of any other executive officer
of the Company.

       (e)  Company  Registration  Obligations.  The  Company  will use its best
efforts to file with the  Securities  and  Exchange  Commission  and  thereafter
maintain the  effectiveness of one or more registration  statements  registering

sale of shares by the Company to  Executive  pursuant to stock  options or other
equity-based awards granted to Executive under Company plans or otherwise or, if
shares are acquired by Executive in a transaction not involving an offer or sale
to Executive but resulting in the acquired shares being "restricted  securities"

       (f)  Reimbursement  of  Expenses.  The Company  will  promptly  reimburse
Executive for all reasonable  business  expenses and  disbursements  incurred by

              for the year in which Executive's employment terminated, an amount
              equal to the portion of annual incentive  compensation  that would
              have become  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash awards) for that year
              if  his  employment  had  not  terminated,  based  on  performance
              actually  achieved  in  that  year  (determined  by the  Committee
              following  completion of the  performance  year),  multiplied by a
              fraction the  numerator  of which is the number of days  Executive

              which is the total number of days in the year of termination;

              outstanding PERS awards, all other long-term incentive awards, and
              all deferral arrangements under Section 5(d), shall be governed by
              the plans and  programs  under  which the awards  were  granted or
              governing  the  deferral,  and all  rights  under the SERP and any
              other benefit plan shall be governed by such plan.

       (b)  Death.  In the  event of  Executive's  death  which  results  in the
termination of Executive's employment,  the Term will terminate, all obligations
of the Company and Executive  under  Sections 1 through 5 of this Agreement will
immediately cease except for obligations  which expressly  continue after death,
and the Company will pay  Executive's  beneficiary  or estate,  and  Executive's
beneficiary or estate will be entitled to receive, the following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   In lieu of any annual  incentive  compensation  under Section 4(b)

<PAGE>

              (i.e.,  excluding the portion payable in PERS or in other non-cash
              awards) for that year if his employment had not terminated,  based
              on performance  actually  achieved in that year (determined by the
              Committee   following   completion  of  the   performance   year),
              multiplied  by a fraction the  numerator of which is the number of
              days  Executive  was  employed  in the year of his  death  and the
              denominator  of which is the  total  number of days in the year of
              death;

       (iii)  The vesting and  exercisability of stock options held by Executive
              at death and all other terms of such options  shall be governed by
              the plans and  programs  and the  agreements  and other  documents
              pursuant to which such options were granted; and

       (iv)   All  restricted   stock  and  deferred  stock  awards,   including
              outstanding PERS awards, all other long-term incentive awards, and
              all deferral arrangements under Section 5(d), shall be governed by
              the plans and  programs  under  which the awards  were  granted or
              governing  the  deferral,  and all  rights  under the SERP and any
              other benefit plan shall be governed by such plan.

       (c)  Disability.  The Company may terminate  the  employment of Executive
hereunder due to the Disability (as defined in Section 8(d)) of Executive.  Such
employment shall terminate at the expiration of the 30-day period referred to in
the  definition of Disability  set forth in Section 8(d),  unless  Executive has
returned to service and  presented to the Company a  certificate  of good health
prior to such  termination  as specified in Section 8(d).  Upon  termination  of
employment,  the  Term  will  terminate,  all  obligations  of the  Company  and
Executive  under Sections 1 through 5 of this Agreement will  immediately  cease
except for obligations which expressly  continue after termination of employment
due to  Disability,  and the Company will pay  Executive,  and Executive will be
entitled to receive, the following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal to the portion of annual incentive  compensation  that would
              have become  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash awards) for that year
              if  his  employment  had  not  terminated,  based  on  performance
              actually  achieved  in  that  year  (determined  by the  Committee
              following  completion of the  performance  year),  multiplied by a
              fraction the  numerator  of which is the number of days  Executive
              was employed in the year of  termination  and the  denominator  of
              which is the total number of days in the year of termination;

       (iii)  Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the

              period  following  termination  during  which such  options may be
              exercised),  such  options  shall be  governed  by the  plans  and
              programs and the agreements and other documents pursuant to

              which such options were granted;

       (iv)   Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target

              deferred  stock awards,  including  outstanding  PERS awards,  and

              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,

              benefit  plans and programs  under Section 5(b) to the extent such
              plans and programs provide medical insurance, disability insurance
              and life  insurance  benefits  (but not  other  benefits,  such as
              pension and retirement  benefits,  provided under Section 5(b)) in
              which   Executive   was   participating   immediately   prior   to
              termination,  the  terms  of  which  allow  Executive's  continued
              participation,  as if Executive had  continued in employment  with
              the  Company  during such period or, if the terms of such plans or
              programs  do  not  allow  Executive's   continued   participation,
              Executive shall be paid a cash payment  equivalent on an after-tax

              described in this Section 6(c)(vi))  Executive would have received
              under  such  plans  or  programs  had  Executive  continued  to be
              employed  during such  period  following  Executive's  termination
              until age 65,  with such  benefits  provided by the Company at the
              same times and in the same manner as such benefits would have been
              provided  to  Executive  under such plans and  programs  (it being
              understood that the value of any insurance-provided  benefits will
              be based on the premium cost to Executive,  which shall not exceed
              the highest risk premium charged by a carrier having an investment
              grade or better credit rating); provided,  however, that Executive
              must continue to satisfy the conditions set forth in Section 10 in
              order to  continue  receiving  the  benefits  provided  under this
              Section 6(c)(vi).

       (d) Other Terms of Payment  Following  Retirement,  Death, or Disability.

event Executive's employment terminates due to Retirement,  death, or Disability

this Section 6 (except in the case of annual incentives in lieu

of which amounts are paid hereunder), including plans and programs adopted after
the date of this  Agreement.  Amounts  payable  under this  Section 6  following
Executive's  termination  of  employment,  other  than those  expressly  payable
following  determination of performance for the year of termination for purposes
of annual incentive  compensation or otherwise  expressly  payable on a deferred
basis,  will be paid as  promptly  as  practicable  after  such  termination  of
employment.

              governed by such plan.

       (b)  Termination by Executive  Other Than For Good Reason.  Executive may
terminate  his  employment  hereunder  voluntarily  for reasons  other than Good

expiration of the Term,  unless a Change in Control (as defined in Section 8(b))
occurs  prior to, and there exists Good Reason at, such date of  expiration.  At

              governed by such plan.

       (c)  Termination  by the Company  Without Cause Prior to or More than Two
Years After a Change in Control.  The Company may  terminate  the  employment of
Executive  hereunder  without Cause,  if at the date of termination no Change in
Control has occurred or such date of termination is at least two years after the
most  recent  Change  in  Control,  upon at  least 90 days'  written  notice  to
Executive.  The  foregoing  notwithstanding,  the Company may elect,  by written
notice to Executive,  to terminate Executive's positions specified in Sections 1
and 3 and all other  obligations of Executive and the Company under Section 3 at
a date earlier than the expiration of such 90-day period, if so specified by the
Company in the written  notice,  provided that Executive  shall be treated as an
employee of the Company  (without any assigned duties) for all other purposes of
this Agreement,  including for purposes of Sections 4 and 5, from such specified
date until the expiration of such 90-day period.  An election by the Company not
to  extend  the Term  pursuant  to  Section  2 hereof  shall be  deemed  to be a
termination of Executive's  employment by the Company  without Cause at the date
of  expiration  of the Term and shall be subject to this  Section 7(c) if at the
date of such  termination  no Change in  Control  has  occurred  or such date of
termination  is at least two  years  after the most  recent  Change in  Control;
provided,  however,  that,  if  Executive  has  attained  age 65 at such date of
termination,  such termination shall be deemed a Retirement of Executive. At the
time  Executive's  employment  is  terminated  by  the  Company  (i.e.,  at  the
expiration  of such  notice  period),  the Term will  terminate,  all  remaining
obligations  of the Company  and  Executive  under  Sections 1 through 5 of this
Agreement will immediately cease (except as expressly  provided below),  and the
Company  will pay  Executive,  and  Executive  will be entitled to receive,  the
following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   Cash in an  aggregate  amount  equal to two  times  the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined  to be payable  under this  Section  7(c)(ii)  shall be
              payable  in  monthly  installments  over the 24  months  following
              termination,  without  interest,  except the  Company may elect to
              accelerate  payment of the remaining balance of such amount and to
              pay it as a lump sum, without discount;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal  to the  portion  of  Executive's  annual  target  incentive
              compensation  potentially  payable  in  cash to

              non-cash  awards)  for the year of  termination,  multiplied  by a
              fraction the  numerator  of which is the number of days  Executive
              was employed in the year of  termination  and the  denominator  of
              which is the total number of days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such  termination,  and, in other respects  (including the
              period  following  termination  during  which such  options may be
              exercised),  such  options  shall be  governed  by the  plans  and
              programs and the agreements and other documents  pursuant to which
              such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,
              and, in other respects, such awards shall be governed by the plans
              and programs and the  agreements and other  documents  pursuant to
              which such awards were granted;

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For a period of two years  after such  termination  (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive  provides  services  during such period  providing
              comparable  benefits.  If the  terms  of  the  Company  plans  and
              programs  referred  to in  this  Section  7(c)(vii)  do not  allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional  benefits described in this Section 7(c)(vii) Executive
              would have  received  under such plans or programs  had  Executive
              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would

              have been provided to Executive  under such plans and programs (it
              being understood that the value of any insurance-provided benefits
              will be based on the premium  cost to  Executive,  which shall not
              exceed the highest  risk  premium  charged by a carrier  having an
              investment grade or better credit rating); provided, however, that
              Executive  must  continue to satisfy the  conditions  set forth in
              Section 10 in order to continue  receiving  the benefits  provided
              under this Section 7(c)(vii).  Executive agrees to promptly notify
              the  Company  of any  employment  or  other  arrangement  by which
              Executive  provides  services  during  the   benefits-continuation
              period  and of  the  nature  and  extent  of  benefits  for  which
              Executive  becomes  eligible during such period which would reduce
              or  terminate  benefits  under  this  Section  7(c)(vii);  and the
              Company be entitled to recover from Executive any payments and the
              fair  market  value of  benefits  previously  made or  provided to
              Executive  hereunder  which  would not have been paid  under  this
              Section  7(c)(vii)  if the Company  had  received  adequate  prior
              notice as required by this sentence.

       (d)  Termination  by Executive  for Good Reason Prior to or More than Two
Years  After a  Change  in  Control.  Executive  may  terminate  his  employment
hereunder  for Good  Reason,  prior to a Change in  Control  or after the second
anniversary  of the most recent Change in Control,  upon 90 days' written notice
to the Company; provided,  however, that, if the Company has corrected the basis
for such Good Reason within 30 days after receipt of such notice,  Executive may
not terminate his employment for Good Reason,  and therefore  Executive's notice
of termination will automatically  become null and void. At the time Executive's
employment is terminated by Executive for Good Reason (i.e.,  at the  expiration
of such notice period), the Term will terminate,  all obligations of the Company
and Executive  under  Sections 1 through 5 of this  Agreement  will  immediately
cease (except as expressly  provided below), and the Company will pay Executive,
and Executive will be entitled to receive, the following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   Cash in an  aggregate  amount  equal to two  times  the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined  to be payable  under this  Section  7(d)(ii)  shall be
              payable  in  monthly  installments  over the 24  months  following
              termination,  without  interest,  except the  Company may elect to
              accelerate  payment of the remaining balance of such amount and to
              pay it as a lump sum, without discount;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)

              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination, multiplied by a fraction the numerator of which is
              the  number  of  days  Executive  was  employed  in  the  year  of
              termination  and the  denominator  of which is the total number of
              days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such  termination,  and, in other respects  (including the
              period  following  termination  during  which such  options may be
              exercised),  such  options  shall be  governed  by the  plans  and
              programs and the agreements and other documents  pursuant to which
              such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,
              and, in other respects, such awards shall be governed by the plans
              and programs and the  agreements and other  documents  pursuant to
              which such awards were granted;

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For a period of two years  after such  termination  (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive  provides  services  during such period  providing
              comparable  benefits.  If the  terms  of  the  Company  plans  and
              programs  referred  to in  this  Section  7(d)(vii)  do not  allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional  benefits described in this Section 7(d)(vii) Executive
              would have  received  under such plans or programs  had  Executive

                                      -13-

<PAGE>

              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would have been provided to Executive  under such
              plans  and  programs  (it being  understood  that the value of any
              insurance-provided  benefits  will be based on the premium cost to
              Executive, which shall not exceed the highest risk premium charged
              by a carrier having an investment  grade or better credit rating);
              provided,  however,  that  Executive  must continue to satisfy the
              conditions set forth in Section 10 in order to continue  receiving
              the  benefits  provided  under this Section  7(d)(vii).  Executive
              agrees to promptly  notify the Company of any  employment or other
              arrangement  by  which  Executive  provides  services  during  the
              benefits-continuation  period  and of the  nature  and  extent  of
              benefits for which Executive  becomes  eligible during such period
              which  would  reduce or  terminate  benefits  under  this  Section
              7(d)(vii);  and the  Company  shall be  entitled  to recover  from
              Executive  any  payments  and the fair  market  value of  benefits
              previously made or provided to Executive hereunder which would not
              have been paid under this  Section  7(d)(vii)  if the  Company had
              received adequate prior notice as required by this sentence.

If any  payment or benefit  under this  Section  7(d) is based on Base Salary or
other level of compensation  or benefits at the time of Executive's  termination
and if a reduction in such Base Salary or other level of compensation or benefit
was the basis for Executive's  termination for Good Reason, then the Base Salary
or other level of  compensation in effect before such reduction shall be used to
calculate payments or benefits under this Section 7(d).

       (e)  Termination  by the Company  Without  Cause Within Two Years After a
Change in  Control.  The Company  may  terminate  the  employment  of  Executive
hereunder without Cause,  simultaneously with or within two years after a Change
in Control,  upon at least 90 days' written  notice to Executive.  The foregoing
notwithstanding,  the  Company may elect,  by written  notice to  Executive,  to
terminate  Executive's  positions  specified  in  Sections 1 and 3 and all other
obligations  of Executive and the Company under Section 3 at a date earlier than
the expiration of such 90-day notice  period,  if so specified by the Company in
the written  notice,  provided that Executive shall be treated as an employee of
the  Company  (without  any  assigned  duties)  for all other  purposes  of this
Agreement,  including for purposes of Sections 4 and 5, from such specified date
until the  expiration of such 90-day  period.  An election by the Company not to
extend the Term pursuant to Section 2 hereof shall be deemed to be a termination
of Executive's employment by the Company without Cause at the date of expiration
of the  Term and  shall  be  subject  to this  Section  7(e) if the date of such
termination  coincides  with or is within two years  after a Change in  Control;
provided,  however,  that,  if  Executive  has  attained  age 65 at such date of
termination,  such termination shall be deemed a Retirement of Executive. At the
time  Executive's  employment  is  terminated  by  the  Company  (i.e.,  at  the
expiration  of such  notice  period),  the Term will  terminate,  all  remaining
obligations  of the Company  and  Executive  under  Sections 1 through 5 of this
Agreement will immediately cease (except as expressly  provided below),  and the
Company  will pay  Executive,  and  Executive  will be entitled to receive,  the
following:

       (i)    Executive's Compensation Accrued at Termination;

                                      -14-

       (ii)   Cash in an  aggregate  amount  equal to three times the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined to be payable under this Section 7(e)(ii) shall be paid
              by  the  Company   not  later  than  15  days  after   Executive's
              termination;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal  to the  portion  of  Executive's  annual  target  incentive
              compensation  potentially  payable  in  cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for  the  year  of  termination,  multiplied  by  a  fraction  the
              numerator of which is the number of days Executive was employed in
              the year of termination  and the denominator of which is the total
              number of days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such termination, and any such options granted on or after
              the date hereof shall remain outstanding and exercisable until the
              stated  expiration  date  of  the  Option  as  though  Executive's
              employment did not terminate, and, in other respects, such options
              shall be governed by the plans and programs and the agreements and
              other documents pursuant to which such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,
              and, in other respects, such awards shall be governed by the plans
              and programs and the  agreements and other  documents  pursuant to
              which such awards were granted;

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For  purposes  of the  SERP,  Executive  shall  be  credited  with
              additional years of age and/or years of Service (as defined in the
              SERP)  if  and  to  the  extent   

                                      -15-

              required  so  that  Executive's  termination  will  qualify  as  a
              "Retirement"  within the meaning of the SERP and so that Executive
              will be entitled the maximum  "Retirement  Benefit" in  accordance
              with Section 3.1 of the SERP.

       (viii) For a period of three years after such  termination (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive  provides  services  during such period  providing
              comparable  benefits.  If the  terms  of  the  Company  plans  and
              programs  referred  to in this  Section  7(e)(viii)  do not  allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional benefits described in this Section 7(e)(viii) Executive
              would have  received  under such plans or programs  had  Executive
              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would have been provided to Executive  under such
              plans  and  programs  (it being  understood  that the value of any
              insurance-provided  benefits  will be based on the premium cost to
              Executive, which shall not exceed the highest risk premium charged
              by a carrier having an investment  grade or better credit rating);
              provided,  however,  that  Executive  must continue to satisfy the
              conditions set forth in Section 10 in order to continue  receiving
              the benefits  provided  under this Section  7(e)(viii).  Executive
              agrees to promptly  notify the Company of any  employment or other
              arrangement  by  which  Executive  provides  services  during  the
              benefits-continuation  period  and of the  nature  and  extent  of
              benefits for which Executive  becomes  eligible during such period
              which  would  reduce or  terminate  benefits  under  this  Section
              7(e)(viii);  and the Company  shall be  entitled  to recover  from
              Executive  any  payments  and the fair  market  value of  benefits
              previously made or provided to Executive hereunder which would not
              have been paid under this  Section  7(e)(viii)  if the Company had
              received adequate prior notice as required by this sentence.

       (f)  Termination  by Executive  for Good Reason  Within Two Years After a
Change in Control.  Executive may terminate  his  employment  hereunder for Good
Reason,  simultaneously with or within two years after a Change in Control, upon
90 days' written notice to the Company; provided,  however, that, if the Company
has  corrected  the basis for such Good Reason  within 30 days after  receipt of
such notice,  Executive may not terminate his  employment  for Good Reason,  and
therefore  Executive's notice of termination will automatically  become null and
void.  At the time  Executive's  employment  is terminated by Executive for Good

Reason (i.e., at the expiration of such notice period), the Term will terminate,
all  obligations of the Company and Executive under Sections 1 through 5 of this
Agreement will immediately cease (except as expressly  provided below),  and the
Company  will pay  Executive,  and  Executive  will be entitled to receive,  the
following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   Cash in an  aggregate  amount  equal to three times the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined to be payable under this Section 7(f)(ii) shall be paid
              by  the  Company   not  later  than  15  days  after   Executive's
              termination;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal  to the  portion  of  Executive's  annual  target  incentive
              compensation  potentially  payable  in  cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for  the  year  of  termination,  multiplied  by  a  fraction  the
              numerator of which is the number of days Executive was employed in
              the year of termination  and the denominator of which is the total
              number of days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such termination, and any such options granted on or after
              the date hereof shall remain outstanding and exercisable until the
              stated  expiration  date  of  the  Option  as  though  Executive's
              employment did not terminate, and, in other respects, such options
              shall be governed by the plans and programs and the agreements and
              other documents pursuant to which such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,
              and, in other respects, such awards shall be governed by the plans
              and programs and the  agreements and other  documents  pursuant to
              which such awards were granted;

                                      -17-

<PAGE>

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For  purposes  of the  SERP,  Executive  shall  be  credited  with
              additional years of age and/or years of Service (as defined in the
              SERP)  if  and  to  the  extent   required  so  that   Executive's
              termination  will qualify as a "Retirement"  within the meaning of
              the  SERP  and so that  Executive  will be  entitled  the  maximum
              "Retirement Benefit" in accordance with Section 3.1 of the SERP.

       (viii) For a period of three years after such  termination (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive  provides  services  during such period  providing
              comparable  benefits.  If the  terms  of  the  Company  plans  and
              programs  referred  to in this  Section  7(f)(viii)  do not  allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional benefits described in this Section 7(f)(viii) Executive
              would have  received  under such plans or programs  had  Executive
              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would have been provided to Executive  under such
              plans  and  programs  (it being  understood  that the value of any
              insurance-provided  benefits  will be based on the premium cost to
              Executive, which shall not exceed the highest risk premium charged
              by a carrier having an investment  grade or better credit rating);
              provided,  however,  that  Executive  must continue to satisfy the
              conditions set forth in Section 10 in order to continue  receiving
              the benefits  provided  under this Section  7(f)(viii).  Executive
              agrees to promptly  notify the Company of any  employment or other
              arrangement  by  which  Executive  provides  services  during  the
              benefits-continuation  period  and of the  nature  and  extent  of
              benefits for which Executive  becomes  eligible during such period
              which  would  reduce or  terminate  benefits  under  this  Section
              7(f)(viii);  and the Company  shall be  entitled  to recover  from
              Executive  any  payments  and the fair  market  value of  benefits
              previously made or provided to Executive hereunder which would not
              have been paid under this  Section  7(f)(viii)  if the Company had
              received adequate prior notice as required by this sentence.

If any  payment or benefit  under this  Section  7(f) is based on Base Salary or
other level of 

                                      -18-

<PAGE>

compensation  or  benefits  at the  time  of  Executive's  termination  and if a
reduction in such Base Salary or other level of  compensation or benefit was the
basis for Executive's termination for Good Reason, then the Base Salary or other
level of compensation in effect before such reduction shall be used to calculate
payments or benefits under this Section 7(f).

       (g) Other Terms Relating to Certain Terminations of Employment. Whether a
termination is deemed to be at or within two years after a Change in Control for
purposes  of  Sections  7(c),  (d),  (e),  or (f) is  determined  at the date of
termination,  regardless  of whether the Change in Control  had  occurred at the
time a notice of  termination  was given.  In the event  Executive's  employment
terminates for any reason set forth in Section 7(b) through (f),  Executive will
be  entitled to the benefit of any terms of plans or  agreements  applicable  to
Executive  which are more  favorable  than  those  specified  in this  Section 7
(except  in the case of  annual  incentives  in lieu of which  amounts  are paid
hereunder).   Amounts  payable  under  this  Section  7  following   Executive's
termination  of  employment,  other than those  expressly  payable on a deferred
basis,  will be paid as  promptly as  practicable  after such a  termination  of
employment,  and such amounts payable under Section 7(e) or 7(f) will be paid in
no event later than 15 days after  Executive's  termination of employment unless
not determinable within such period.

       8.     Definitions Relating to Termination Events.

       (a)  "Cause."  For  purposes  of  this  Agreement,   "Cause"  shall  mean
Executive's

       (i)    willful and continued failure to substantially  perform his duties
              hereunder  (other than any such failure  resulting from incapacity
              due to physical  or mental  illness or  disability  or any failure
              after the issuance of a notice of  termination  by  Executive  for
              Good Reason) which failure is demonstrably and materially damaging
              to the financial condition or reputation of the Company and/or its
              subsidiaries, and which failure continues more than 48 hours after
              a written  demand for  substantial  performance  is  delivered  to
              Executive by the Board, which demand  specifically  identifies the
              manner  in  which  the  Board  believes  that  Executive  has  not
              substantially  performed his duties hereunder and the demonstrable
              and material damage caused thereby; or

       (ii)   the willful engaging by Executive in conduct which is demonstrably
              and materially injurious to the Company, monetarily or otherwise.

No act, or failure to act, on the part of  Executive  shall be deemed  "willful"
unless done,  or omitted to be done,  by Executive not in good faith and without
reasonable  belief that his action or omission  was in the best  interest of the
Company.  Notwithstanding  the foregoing,  Executive shall not be deemed to have
been  terminated  for Cause unless and until there shall have been  delivered to
Executive a copy of the resolution duly adopted by the  affirmative  vote of not
less  than  three-quarters  (3/4) of the  entire  membership  of the  Board at a
meeting of the Board (after  reasonable  notice to Executive and an  opportunity
for Executive,  together with Executive's counsel, to be heard before the Board)
finding that,  in the good faith  opinion of the Board,

                                      -19-

<PAGE>

Executive  was  guilty  of  conduct  set  forth  above  in this  definition  and
specifying the particulars thereof in detail.

       (b) "Change in  Control."  For purposes of this  Agreement,  a "Change in
Control" shall be deemed to have occurred if, during the term of this Agreement:

       (i)    any  "Person," as such term is used for purposes of Section  13(d)
              or 14(d) of the  Securities  Exchange Act of 1934, as amended (the
              "Exchange  Act")  (other  than the  Company,  any trustee or other
              fiduciary holding securities under an employee benefit plan of the
              Company,  or any company  owned,  directly or  indirectly,  by the
              stockholders of the Company in substantially  the same proportions
              as  their  ownership  of  stock  of  the  Company),   becomes  the
              "Beneficial  Owner" (as defined in Rule 13d-3  under the  Exchange
              Act),  directly  or  indirectly,  of  securities  of  the  Company
              representing  20% or  more of the  combined  voting  power  of the
              Company's then-outstanding securities;

       (ii)   during any period of twenty-four  months (not including any period
              prior to the effectiveness of this Agreement),  individuals who at
              the  beginning of such period  constitute  the Board,  and any new
              director (other than (A) a director  nominated by a Person who has
              entered into an agreement with the Company to effect a transaction
              described  in  Sections  (8)(b)(i),  (iii) or (iv)  hereof,  (B) a
              director  nominated  by any Person  (including  the  Company)  who
              publicly  announces  an  intention  to take or to consider  taking
              actions  (including,  but not limited to, an actual or  threatened
              proxy contest) which if consummated  would  constitute a Change in
              Control  or (C) a  director  nominated  by any  Person  who is the
              Beneficial  Owner,  directly or  indirectly,  of securities of the
              Company  representing  10% or more of the combined voting power of
              the  Company's   securities)   whose  election  by  the  Board  or
              nomination for election by the Company's stockholders was approved
              in advance by a vote of at least two-thirds (2/3) of the directors
              then still in office who either were directors at the beginning of
              the  period or whose  election  or  nomination  for  election  was
              previously  so  approved,  cease for any reason to  constitute  at
              least a majority thereof;

       (iii)  the  stockholders of the Company approve any transaction or series
              of transactions  under which the Company is merged or consolidated
              with any other company,  other than a merger or consolidation  (A)
              which  would  result  in the  voting  securities  of  the  Company
              outstanding  immediately  prior  thereto  continuing  to represent
              (either by remaining outstanding or by being converted into voting
              securities  of the  surviving  entity)  more  than  66 2/3% of the
              combined  voting power of the voting  securities of the Company or
              such surviving entity outstanding immediately after such merger 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  

                                      -20-

<PAGE>

              substantially all of the Company's assets; or

       (v)    the Board adopts a resolution to the effect that,  for purposes of
              this Agreement, a Change in Control has occurred.

       (c)   "Compensation   Accrued  at  Termination."  For  purposes  of  this
Agreement, "Compensation Accrued at Termination" means the following:

       (i)    The unpaid  portion of annual base salary at the rate payable,  in
              accordance  with Section 4(a) hereof,  at the date of  Executive's
              termination  of  employment,   pro  rated  through  such  date  of
              termination,  payable in accordance with the Company's regular pay
              schedule;

       (ii)   All vested, nonforfeitable amounts owing or accrued at the date of
              Executive's  termination of employment  under any compensation and
              benefit plans, programs, and arrangements set forth or referred to
              in Sections  4(b) and 5(a) and 5(b) hereof  (including  any earned
              and vested annual incentive  compensation and long-term  incentive
              award) in which  Executive  theretofore  participated,  payable in
              accordance  with the terms and conditions of the plans,  programs,
              and  arrangements   (and  agreements  and  documents   thereunder)
              pursuant to which such  compensation  and benefits were granted or
              accrued; and

       (iii)  Reasonable   business  expenses  and  disbursements   incurred  by
              Executive  prior to Executive's  termination of employment,  to be
              reimbursed  to  Executive,  as  authorized  under Section 5(f), in
              accordance  the Company's  reimbursement  policies as in effect at
              the date of such termination.

       (d)  "Disability."  For purposes of this  Agreement,  "Disability"  means
Executive's  absence  from  the  full-time  performance  of  Executive's  duties
hereunder  for six  consecutive  months  as a result  of his  incapacity  due to
physical or mental  illness or  disability,  and,  within 30 days after  written
notice of termination is thereafter  given by the Company,  Executive shall have
not returned to the full-time performance of such duties.

       (e) "Good  Reason." For purposes of this  Agreement,  "Good Reason" shall
mean, without Executive's express written consent,  the occurrence of any of the
following  circumstances  unless,  in the case of subsections (i), (iv), (vi) or
(viii)  hereof,  such  circumstances  are fully  corrected  prior to the date of
termination specified in the notice of termination given in respect thereof:

       (i)    the   assignment   to  Executive  of  duties   inconsistent   with
              Executive's  position  and  status  hereunder,  or an  alteration,
              adverse  to  Executive,  in  the  nature  of  Executive's  duties,
              responsibilities,  and authorities,  Executive's  positions or the
              conditions  of  Executive's  employment  from those  specified  in
              Section 3 or otherwise  hereunder (other than inadvertent  actions
              which  are  promptly   remedied);   for  this  purpose,  it  shall
              constitute  "Good  Reason"  under  this  subsection  (e)(i) if (A)
              Executive  shall be required to report to and take  direction 

                                      -21-

<PAGE>

              from any person or body other than the Board of  Directors  of the
              Company;  and (B) if  Executive  shall be removed  from the Board,
              from the  office  of  Chairman  of the  Board,  or from any  Board
              committee on which  Executive has served during the Term, or there
              occurs any failure of Executive to be  nominated,  reappointed  or
              reelected as a member of the Board,  as Chairman of the Board,  or
              as a member of any Board  committee on which he has served  during
              the Term, including a failure of the Board or stockholders to take
              such actions  (notwithstanding their legal right to do so), except
              the  foregoing  shall not  constitute  Good Reason if occurring in
              connection  with the  termination  of  Executive's  employment for
              Cause, Disability,  Retirement,  as a result of Executive's death,
              or as a result of action by or with the consent of Executive;  for
              purposes of this Section  8(e)(i),  references to the Company (and
              the Board and  stockholders  of the Company) refer to the ultimate
              parent  company (and its board and  stockholders)  succeeding  the
              Company following an acquisition in which the corporate  existence
              of the Company continues, in accordance with Section 12(b);

       (ii)   (A) a reduction by the Company in Executive's Base Salary, (B) the
              setting of  Executive's  annual target  incentive  opportunity  or
              payment of earned annual  incentive in amounts less than specified
              under or otherwise not in conformity with Section 4 hereof,  (C) a
              change in  compensation or benefits not in conformity with Section
              5, or (D) a reduction,  after a Change in Control,  in perquisites
              from the level of such perquisites as in effect  immediately prior
              to the Change in  Control  or as the same may have been  increased
              from  time  to  time  after  the  Change  in  Control  except  for
              across-the-board  perquisite  reductions  similarly  affecting all
              senior  executives of the Company and all senior executives of any
              Person in control of the Company;

       (iii)  the relocation of the principle  place of  Executive's  employment
              not in  conformity  with Section 3(b)  hereof;  for this  purpose,
              required  travel on the Company's  business will not  constitute a
              relocation  so long as the extent of such travel is  substantially
              consistent with Executive's  customary business travel obligations
              in periods prior to the Effective Date;

       (iv)   the  failure by the  Company to pay to  Executive  any  portion of
              Executive's  compensation or to pay to Executive any portion of an
              installment   of   deferred   compensation   under  any   deferred
              compensation  program of the Company within seven days of the date
              such compensation is due;

       (v)    the  failure by the  Company to  continue  in effect any  material
              compensation  or  benefit  plan in  which  Executive  participated
              immediately  prior to a Change in  Control,  unless  an  equitable
              arrangement  (embodied  in an ongoing  substitute  or  alternative
              plan) has been made with  respect to such plan,  or the failure by
              the Company to continue Executive's  participation  therein (or in
              such  substitute or  alternative  plan) on a basis not  materially
              less favorable,  both in terms of the amounts of benefits provided
              and the  level  of  Executive's  participation  relative  to 

                                      -22-

<PAGE>

              other  participants,  as  existed  at the  time of the  Change  in
              Control;

       (vi)   the failure of the Company to obtain a satisfactory agreement from
              any  successor  to the  Company  to  fully  assume  the  Company's
              obligations and to perform under this  Agreement,  as contemplated
              in  Section  12(b)  hereof,  in a form  reasonably  acceptable  to
              Executive;

       (vii)  any  election  by the  Company  not to  extend  the  Term  of this
              Agreement  at the next  possible  extension  date under  Section 2
              hereof,  unless  Executive  will have attained age 65 at or before
              such extension date; or

       (viii) any  other   failure  by  the  Company  to  perform  any  material
              obligation  under,  or  breach  by the  Company  of  any  material
              provision of, this Agreement.

       (f)  "Potential  Change in Control"  For  purposes of this  Agreement,  a
"Change in Control" shall be deemed to have occurred if, during the term of this
Agreement:

       (i)    the Company enters into an agreement,  the  consummation  of which
              would result in the occurrence of a Change in Control;

       (ii)   any Person (including the Company) publicly announces an intention
              to take or to consider  taking actions which if consummated  would
              constitute a Change in Control; or

       (iii)  the Board adopts a resolution to the effect that,  for purposes of
              this Agreement, a Potential Change in Control has occurred.

       9. Rabbi  Trust  Obligation  Upon  Potential  Change in  Control;  Excise
Tax-Related Provisions.

       (a) Rabbi Trust Funded Upon Potential Change in Control.  In the event of
a  Potential  Change in  Control,  the  Company  shall,  not later  than 15 days
thereafter,  have established one or more rabbi trusts and shall deposit therein
cash in an amount  sufficient  to  provide  for full  payment  of all  potential
obligations of the Company that would arise assuming consummation of a Change in
Control and a subsequent  termination  of Executive's  employment  under Section
7(e) or 7(f).  Such rabbi trust(s)  shall be irrevocable  and shall provide that
the Company may not,  directly or  indirectly,  use or recover any assets of the
trust(s)  until  such time as all  obligations  which  potentially  could  arise
hereunder  have been  settled  and paid in full,  subject  only to the claims of
creditors  of the  Company  in the  event of  insolvency  or  bankruptcy  of the
Company; provided, however, that if no Change in Control has occurred within two
years after such Potential  Change in Control,  such rabbi trust(s) shall at the
end of such two-year  period become  revocable and may  thereafter be revoked by
the Company.

       (b) Gross-up If Excise Tax Would Apply.  In the event  Executive  becomes
entitled to any amounts  payable in connection with a Change in Control or other
change in control  (whether or not such  amounts  are  payable  pursuant to this
Agreement) (the  "Severance 

                                      -23-

<PAGE>

Payments"),  if any of such  Severance  Payments  are  subject  to the tax  (the
"Excise Tax") imposed by Section 4999 of the Code (or any similar federal, state
or local tax that may hereafter be imposed),  the Company shall pay to Executive
at the time  specified in Section  9(b)(iii)  hereof an  additional  amount (the
"Gross-Up  Payment")  such that the net  amount  retained  by  Executive,  after
deduction of any Excise Tax on the Total Payments (as  hereinafter  defined) and
any federal, state and local income tax and Excise Tax upon the payment provided
for by Section 9(b)(i), shall be equal to the Total Payments.

       (i)    For purposes of determining  whether any of the Severance Payments
              will be subject  to the  Excise Tax and the amount of such  Excise
              Tax:

              (A)    any other  payments or benefits  received or to be received
                     by  Executive  in  connection  with a Change in  Control or
                     Executive's  termination of employment (whether pursuant to
                     the terms of this Agreement or any other plan,  arrangement
                     or  agreement  with the Company,  any Person whose  actions
                     result in a Change in Control or any Person affiliated with
                     the  Company  or such  Person)  (which,  together  with the
                     Severance Payments,  constitute the "Total Payments") shall
                     be treated as  "parachute  payments"  within the meaning of
                     Section  280G(b)(2) of the Code, and all "excess  parachute
                     payments"  within the meaning of Section  280G(b)(1) of the
                     Code shall be treated as subject to the Excise Tax,  unless
                     in  the  opinion  of   nationally-recognized   tax  counsel
                     selected by Executive  such other  payments or benefits (in
                     whole or in part) do not constitute parachute payments,  or
                     such  excess  parachute  payments  (in  whole  or in  part)
                     represent  reasonable  compensation  for services  actually
                     rendered  within the meaning of Section  280G(b)(4)  of the
                     Code in excess of the base  amount  within  the  meaning of
                     Section  280G(b)(3)  of  the  Code,  or are  otherwise  not
                     subject to the Excise Tax;

              (B)    the amount of the Total  Payments which shall be treated as
                     subject  to the  Excise Tax shall be equal to the lesser of
                     (x) the  total  amount of the  Total  Payments  and (y) the
                     amount of excess  parachute  payments within the meaning of
                     Section  280G(b)(1)  of the Code  (after  applying  Section
                     9(b)(i)(A) hereof); and

              (C)    the value of any non-cash benefits or any deferred payments
                     or benefit shall be  determined by a  nationally-recognized
                     accounting  firm selected by Executive in  accordance  with
                     the principles of Sections 280G(d)(3) and (4) of the Code.

       (ii)   For purposes of  determining  the amount of the Gross-Up  Payment,
              Executive  shall be  deemed  to pay  federal  income  taxes at the
              highest  marginal rate of federal income  taxation in the calendar
              year in which  the  Gross-Up  Payment  is to be made and state and
              local income taxes at the highest marginal rate of taxation in the
              state  and  locality  of  Executive's  residence  on the  Date  of
              Termination,  net of the maximum reduction in federal income taxes
              which could 

                                      -24-

<PAGE>

              be obtained from  deduction of such state and local taxes.  In the
              event that the Excise Tax is  subsequently  determined  to be less
              than  the  amount  taken  into  account  hereunder  at the time of
              termination of Executive's  employment,  Executive  shall repay to
              the Company within ten days after the time that the amount of such
              reduction in Excise Tax is finally  determined  the portion of the
              Gross-Up Payment  attributable to such reduction (plus the portion
              of the Gross-Up Payment attributable to the Excise Tax and federal
              and state and local  income tax  imposed on the  Gross-Up  Payment
              being repaid by Executive if such repayment results in a reduction
              in Excise  Tax  and/or  federal  and state  and local  income  tax
              deduction)  plus  interest on the amount of such  repayment at the
              rate provided in Section  1274(b)(2)(B)  of the Code. In the event
              that the Excise Tax is  determined to exceed the amount taken into
              account  hereunder at the time of the  termination  of Executive's
              employment  (including  by reason of any payment the  existence or
              amount of which cannot be  determined  at the time of the Gross-Up
              Payment), the Company shall make an additional gross-up payment in
              respect  of such  excess  within  ten days after the time that the
              amount of such excess is finally determined.

       (iii)  The  payments  provided for in this Section 9(b) shall be made not
              later than the fifteenth  day  following  the date of  Executive's
              termination of employment;  provided,  however, that if the amount
              of such  payments  cannot be finally  determined on or before such
              day,  the Company  shall pay to Executive on such day an estimate,
              as determined in good faith by the Company,  of the minimum amount
              of such  payments  and shall pay the  remainder  of such  payments
              (together   with   interest  at  the  rate   provided  in  Section
              1274(b)(2)(B)  of the Code) as soon as the amount  thereof  can be
              determined  but in no event later than the thirtieth day after the
              date of Executive's  termination of employment.  In the event that
              the  amount  of  the   estimated   payments   exceeds  the  amount
              subsequently  determined  to have  been  due,  such  excess  shall
              constitute  a loan by the  Company  to  Executive,  payable on the
              fifteenth  day after  the  demand by the  Company  (together  with
              interest  at the rate  provided  in Section  1274(b)(2)(B)  of the
              Code).

       (iv)   All  determinations  under this  Section 9(b) shall be made at the
              expense  of  the  Company  by  a  nationally   recognized   public
              accounting  firm  selected by  Executive,  and such  determination
              shall be binding upon Executive and the Company.

       10.    Non-Competition   and   Non-Disclosure;   Executive   Cooperation;
              Non-Disparagement.

       (a)  Non-Competition.  Without  the  consent  in  writing  of the  Board,
Executive  will not,  at any time  during the Term and for a period of two years
following termination of Executive's  employment for any reason, acting alone or
in conjunction with others,  directly or indirectly (i) engage (either as owner,
investor, partner,  stockholder,  employer,  employee,  consultant,  advisor, or
director) in any business in which he has been directly engaged on

                                      -25-

<PAGE>

behalf of the  Company  or any  affiliate,  or has  supervised  as an  executive
thereof,  during  the last two  years  prior to such  termination,  or which was
engaged  in or  planned  by the  Company  or an  affiliate  at the  time of such
termination,  in any  geographic  area in which such  business was  conducted or
planned to be conducted;  (ii) induce any customers of the Company or any of its
affiliates  with whom Executive has had contacts or  relationships,  directly or
indirectly,  during and within the scope of her  employment  with the Company or
any of its  affiliates,  to curtail or cancel their business with the Company or
any such affiliate;  (iii) induce, or attempt to influence,  any employee of the
Company or any of its affiliates to terminate employment;  or (iv) solicit, hire
or retain as an employee or independent contractor, or assist any third party in
the solicitation,  hire, or retention as an employee or independent  contractor,
any person who during the  previous  12 months was an employee of the Company or
any affiliate;  provided,  however,  that the limitation contained in clause (i)
above shall not apply if  Executive's  employment is terminated as a result of a
termination by the Company  without Cause within two years following a Change in
Control or is terminated by Executive for Good Reason within two years following
a Change in Control;  and provided further,  that activities engaged in by or on
behalf of the Company are not  restricted by this  covenant.  The  provisions of
subparagraphs  (i),  (ii),  (iii),  and (iv)  above are  separate  and  distinct
commitments  independent of each of the other  subparagraphs.  It is agreed that
the  ownership  of not more than one  percent  of the equity  securities  of any
company  having  securities  listed on an  exchange or  regularly  traded in the
over-the-counter market shall not, of itself, be deemed inconsistent with clause
(i) of this Section 10(a).

       (b) Non-Disclosure;  Ownership of Work.  Executive shall not, at any time
during the Term and thereafter (including following  Executive's  termination of
employment for any reason),  disclose,  use,  transfer,  or sell,  except in the
course of  employment  with or other  service to the  Company,  any  proprietary
information,   secrets,   organizational  or  employee  information,   or  other
confidential information belonging or relating to the Company and its affiliates
and customers so long as such information has not otherwise been disclosed or is
not  otherwise  in the public  domain,  except as required by law or pursuant to
legal  process.  In addition,  upon  termination  of employment  for any reason,
Executive  will return to the Company or its  affiliates all documents and other
media  containing  information  belonging  or  relating  to the  Company  or its
affiliates.  Executive  will  promptly  disclose  in writing to the  Company all
inventions,    discoveries,    developments,    improvements   and   innovations
(collectively  referred to as "Inventions") that Executive has conceived or made
during  the Term;  provided,  however,  that in this  context  "Inventions"  are
limited to those which (i) relate in any manner to the existing or  contemplated
business or research  activities  of the  Company and its  affiliates;  (ii) are
suggested by or result from  Executive's  work at the  Company;  or (iii) result
from  the use of the  time,  materials  or  facilities  of the  Company  and its
affiliates.   All  Inventions  will  be  the  Company's   property  rather  than
Executive's.  Should  the  Company  request  it,  Executive  agrees  to sign any
document that the Company may reasonably  require to establish  ownership in any
Invention.

       (c) Cooperation With Regard to Litigation.  Executive agrees to cooperate
with  the  Company,   during  the  Term  and  thereafter   (including  following
Executive's  termination  of  employment  for any  reason),  by  making  himself
available to testify on behalf of the Company or any  subsidiary or affiliate of
the Company,  in any action,  suit,  or  proceeding,  whether  civil,

                                      -26-

<PAGE>

criminal,  administrative,  or investigative,  and to assist the Company, or any
subsidiary or affiliate of the Company, in any such action, suit, or proceeding,
by  providing  information  and  meeting  and  consulting  with the Board or its
representatives or counsel, or representatives or counsel to the Company, or any
subsidiary  or affiliate of the Company,  as  requested.  The Company  agrees to
reimburse  the  Executive,  on an after-tax  basis,  for all  expenses  actually
incurred in connection with his provision of testimony or assistance.

       (d)  Non-Disparagement.  Executive shall not, at any time during the Term
and thereafter,  make statements or representations,  or otherwise  communicate,
directly or indirectly,  in writing,  orally,  or otherwise,  or take any action
which may,  directly or  indirectly,  disparage or be damaging to the Company or
any of its subsidiaries or affiliates or their respective  officers,  directors,
employees,  advisors, businesses or reputations.  Notwithstanding the foregoing,
nothing  in  this  Agreement  shall  preclude  Executive  from  making  truthful
statements that are required by applicable law, regulation or legal process.

       (e) Release of Employment  Claims.  Executive  agrees,  as a condition to
receipt of any termination  payments and benefits provided for in Sections 6 and
7 herein (other than Compensation Accrued at Termination),  that he will execute
a general release  agreement,  in a form satisfactory to the Company,  releasing
any and all claims arising out of Executive's employment (other than enforcement
of this Agreement).

       (f) Forfeiture of Outstanding Options. The provisions of Sections 6 and 7
notwithstanding,  if Executive  willfully and materially  fails to substantially
comply with any  restrictive  covenant  under this Section 10 or  willfully  and
materially fails to substantially comply with any material obligation under this
Agreement,  all options to purchase Common Stock granted by the Company and then
held by Executive or a transferee of Executive  shall be  immediately  forfeited
and thereupon  such options shall be cancelled.  Notwithstanding  the foregoing,
Executive  shall not forfeit  any option  unless and until there shall have been
delivered to him, within six months after the Board (i) had knowledge of conduct
or an event  allegedly  constituting  grounds for such  forfeiture  and (ii) had
reason  to  believe  that  such  conduct  or  event  could be  grounds  for such
forfeiture,  a copy of a resolution duly adopted by a majority  affirmative vote
of the membership of the Board  (excluding  Executive) at a meeting of the Board
called and held for such  purpose  (after  giving  Executive  reasonable  notice
specifying  the nature of the grounds for such  forfeiture  and not less than 30
days to  correct  the acts or  omissions  complained  of,  if  correctable,  and
affording  Executive the  opportunity,  together  with his counsel,  to be heard
before  the  Board)  finding  that,  in the good  faith  opinion  of the  Board,
Executive  has  engaged  and  continues  to engage in conduct  set forth in this
Section 10(f) which constitutes  grounds for forfeiture of Executive's  options;
provided, however, that if any option is exercised after delivery of such notice
and the Board subsequently  makes the determination  described in this sentence,
Executive  shall  be  required  to pay to the  Company  an  amount  equal to the
difference between the aggregate value of the shares acquired upon such exercise
at the date of the Board  determination and the aggregate exercise price paid by
Executive.  Any such forfeiture shall apply to such options  notwithstanding any
term or provision of any option agreement.

       (g)  Survival.  The  provisions  of this  Section  10 shall  survive  the
termination

                                      -27-

of the Term and any termination or expiration of this Agreement.

       11.    Governing Law; Disputes; Arbitration.

       (a) Governing  Law. This Agreement is governed by and is to be construed,
administered,  and  enforced  in  accordance  with  the  laws  of the  State  of
Connecticut,  without regard to conflicts of law  principles,  except insofar as
federal laws and  regulations  and the Delaware  General  Corporation Law may be
applicable.  If under the governing law, any portion of this Agreement is at any
time deemed to be in conflict with any  applicable  statute,  rule,  regulation,
ordinance,  or other  principle  of law,  such  portion  shall be  deemed  to be
modified or altered to the extent  necessary  to conform  thereto or, if that is
not  possible,  to be omitted from this  Agreement.  The  invalidity of any such
portion  shall not affect the  force,  effect,  and  validity  of the  remaining
portion  hereof.  If any court  determines  that any  provision of Section 10 is
unenforceable because of the duration or geographic scope of such provision,  it
is the  parties'  intent  that such  court  shall  have the power to modify  the
duration  or  geographic  scope of such  provision,  as the case may be,  to the
extent necessary to render the provision  enforceable and, in its modified form,
such provision shall be enforced.

       (b) Reimbursement of Expenses in Enforcing  Rights.  All reasonable costs
and expenses (including fees and disbursements of counsel) incurred by Executive
in seeking to  interpret  this  Agreement  or enforce  rights  pursuant  to this
Agreement shall be paid on behalf of or reimbursed to Executive  promptly by the
Company,  whether or not  Executive  is  successful  in  asserting  such rights;
provided, however, that no reimbursement shall be made of such expenses relating
to any  unsuccessful  assertion of rights if and to the extent that  Executive's
assertion  of such  rights  was in bad  faith or  frivolous,  as  determined  by
arbitrators in accordance with Section 11(c) or a court having jurisdiction over
the matter.

       (c)  Arbitration.   Any  dispute  or  controversy  arising  under  or  in
connection  with this Agreement  shall be settled  exclusively by arbitration in
Westport CT by three  arbitrators  in accordance  with the rules of the American
Arbitration  Association  in effect at the time of  submission  to  arbitration.
Judgment  may  be  entered  on  the  arbitrators'  award  in  any  court  having
jurisdiction.  For purposes of entering any judgment  upon an award  rendered by
the arbitrators, the Company and Executive hereby consent to the jurisdiction of
any or all of the following courts: (i) the United States District Court for the
District of Connecticut,  (ii) any of the courts of the State of Connecticut, or
(iii) any other court having  jurisdiction.  The Company and  Executive  further
agree that any service of process or notice  requirements in any such proceeding
shall be  satisfied  if the  rules of such  court  relating  thereto  have  been
substantially  satisfied. The Company and Executive hereby waive, to the fullest
extent  permitted by applicable law, any objection which it may now or hereafter
have to such jurisdiction and any defense of inconvenient forum. The Company and
Executive hereby agree that a judgment upon an award rendered by the arbitrators
may be enforced in other  jurisdictions  by suit on the judgment or in any other
manner  provided by law.  Subject to Section  11(b),  the Company shall bear all
costs  and  expenses  arising  in  connection  with any  arbitration  proceeding
pursuant to this Section 11.  Notwithstanding  any provision in this Section 11,
Executive shall be entitled to seek specific performance of Executive's right to
be paid during the pendency of any dispute or  controversy  arising  under or in
connection with this Agreement.

                                      -28-

<PAGE>

       (d)  Interest  on Unpaid  Amounts.  Any amount  which has become  payable
pursuant  to the terms of this  Agreement  or any  decision  by  arbitrators  or
judgment by a court of law  pursuant  to this  Section 11 but which has not been
timely  paid  shall bear  interest  at the prime rate in effect at the time such
amount first becomes payable, as quoted by the Company's principal bank.

       12.    Miscellaneous.

       (a) Integration.  This Agreement cancels and supersedes any and all prior
agreements  and  understandings  between the parties  hereto with respect to the
employment of Executive by the Company,  any parent or predecessor  company, and
the Company's  subsidiaries  during the Term,  except for contracts  relating to
compensation  under  executive  compensation  and employee  benefit plans of the
Company and its subsidiaries. The foregoing notwithstanding, Executive shall not
participate  in  the  Company's   Employee   Protection   Plan.  This  Agreement
constitutes  the entire  agreement among the parties with respect to the matters
herein provided,  and no modification or waiver of any provision hereof shall be
effective  unless in writing and signed by the parties  hereto.  Executive shall
not be entitled to any payment or benefit under this Agreement which  duplicates
a payment  or benefit  received  or  receivable  by  Executive  under such prior
agreements and  understandings  or under any benefit or compensation plan of the
Company.

       (b) Successors;  Transferability. The Company shall require any successor
(whether direct or indirect,  by purchase,  merger,  consolidation or otherwise,
and whether or not the corporate  existence of the Company  continues) to all or
substantially  all of the  business  and/or  assets of the Company to  expressly
assume and agree to perform  this  Agreement  in the same manner and to the same
extent  that the Company  would be required to perform it if no such  succession
had taken place. As used in this Agreement,  "Company" shall mean the Company as
hereinbefore  defined  and  any  successor  to its  business  and/or  assets  as
aforesaid  which  assumes and agrees to perform  this  Agreement by operation of
law, or otherwise and, in the case of an acquisition of the Company in which the
corporate  existence  of the Company  continues,  the  ultimate  parent  company
following such acquisition.  Subject to the foregoing,  the Company may transfer
and assign this Agreement and the Company's  rights and  obligations  hereunder.
Neither this  Agreement nor the rights or  obligations  hereunder of the parties
hereto shall be  transferable  or assignable by Executive,  except in accordance
with the laws of descent and distribution or as specified in Section 12(c).

       (c) Beneficiaries.  Executive shall be entitled to designate (and change,
to the extent  permitted under applicable law) a beneficiary or beneficiaries to
receive any compensation or benefits provided  hereunder  following  Executive's
death.

       (d) Notices.  Whenever under this Agreement it becomes  necessary to give
notice,  such notice shall be in writing,  signed by the party or parties giving
or making the same,  and shall be served on the person or persons for whom it is
intended  or who  should be  advised or  notified,  by Federal  Express or other
similar  overnight  service or by certified or registered  mail,  return receipt
requested,  postage prepaid and addressed to such party at the address set

                                      -29-

forth below or at such other  address as may be designated by such party by like
notice:

         If to the Company:

         IMS HEALTH INCORPORATED
         200 Nyala Farms
         Westport, CT  06880
         Attention:  General Counsel

         If to Executive:

         Robert E. Weissman
         200 Nyala Farms
         Westport, CT  06880

If the parties by mutual agreement supply each other with telecopier numbers for
the purposes of providing notice by facsimile,  such notice shall also be proper
notice under this  Agreement.  In the case of Federal  Express or other  similar
overnight  service,  such notice or advice shall be effective when sent, and, in
the cases of certified or  registered  mail,  shall be effective  two days after
deposit into the mails by delivery to the U.S. Post Office.

       (e)  Reformation.  The invalidity of any portion of this Agreement  shall
not deemed to render the remainder of this Agreement invalid.

       (f)  Headings.  The headings of this  Agreement  are for  convenience  of
reference only and do not constitute a part hereof.

       (g) No General  Waivers.  The failure of any party at any time to require
performance  by any  other  party of any  provision  hereof  or to resort to any
remedy  provided  herein or at law or in equity shall in no way affect the right
of such party to require  such  performance  or to resort to such  remedy at any
time  thereafter,  nor shall  the  waiver by any party of a breach of any of the
provisions  hereof be deemed  to be a waiver  of any  subsequent  breach of such
provisions.  No such waiver shall be  effective  unless in writing and signed by
the party against whom such waiver is sought to be enforced.

       (h) No  Obligation To Mitigate.  Executive  shall not be required to seek
other  employment  or  otherwise  to  mitigate   Executive's  damages  upon  any
termination  of employment;  provided,  however,  that, to the extent  Executive
receives from a subsequent  employer health or other insurance benefits that are
substantially  similar to the benefits  referred to in Section 5(b) hereof,  any
such  benefits to be provided by the  Company to  Executive  following  the Term
shall be correspondingly reduced.

       (i) Offsets;  Withholding. The amounts required to be paid by the Company
to  Executive  pursuant to this  Agreement  shall not be subject to offset other
than with respect to any amounts  that are owed to the Company by Executive  due
to his receipt of funds as a result of his  fraudulent  activity.  The foregoing
and other provisions of this Agreement notwithstanding,  all payments to be made
to  Executive  under  this  Agreement,  including  under  Sections  6 and 7,  or
otherwise by the Company,  will be subject to  withholding  to satisfy  required
withholding taxes and other required deductions.

       (j)  Successors  and Assigns.  This  Agreement  shall be binding upon and
shall

                                      -30-

<PAGE>

inure to the benefit of  Executive,  his heirs,  executors,  administrators  and
beneficiaries, and shall be binding upon and inure to the benefit of the Company
and its successors and assigns.

       (k) Counterparts. This Agreement may be executed in counterparts, each of
which  shall  be  deemed  to be an  original  but  all of  which  together  will
constitute one and the same instrument.

       13.    Indemnification.

       All rights to indemnification by the Company now existing in favor of the
Executive as provided in the Company's  Certificate of  Incorporation or By-laws
or  pursuant  to other  agreements  in  effect  on or  immediately  prior to the
Effective  Date shall  continue in full force and effect from the Effective Date
(including all periods after the expiration of the Term),  and the Company shall
also advance  expenses for which  indemnification  may be ultimately  claimed as
such expenses are incurred to the fullest extent permitted under applicable law,
subject to any  requirement  that the Executive  provide an undertaking to repay
such advances if it is ultimately  determined that the Executive is not entitled
to indemnification;  provided,  however,  that any determination  required to be
made with respect to whether the Executive's conduct complies with the standards
required to be met as a condition of  indemnification or advancement of expenses
under applicable law and the Company's Certificate of Incorporation, By-laws, or
other agreement shall be made by independent  counsel mutually acceptable to the
Executive  and the  Company  (except to the extent  otherwise  required by law).
After  the  date  hereof,  the  Company  shall  not  amend  its  Certificate  of
Incorporation or By-laws or any agreement in any manner which adversely  affects
the  rights  of the  Executive  to  indemnification  thereunder.  Any  provision
contained herein  notwithstanding,  this Agreement shall not limit or reduce any
rights of the  Executive  to  indemnification  pursuant  to  applicable  law. In
addition, the Company will maintain directors' and officers' liability insurance
in effect and covering acts and omissions of Executive during the Term and for a
period of six years  thereafter on terms  substantially  no less  favorable than
those in effect on the Effective Date.

       IN WITNESS  WHEREOF,  Executive has hereunto set his hand and the Company
has caused  this  instrument  to be duly  executed  as of the day and year first
above written.

                    Employment Agreement for Victoria R. Fash


     THIS  EMPLOYMENT  AGREEMENT  by and  between  IMS  HEALTH  INCORPORATED,  a
Delaware  corporation (the "Company"),  and Victoria R. Fash ("Executive") shall
become effective as of July 1, 1998 (the "Effective Date").

                               W I T N E S S E T H

     WHEREAS, Executive has served the Company and its predecessors in executive
and senior executive capacities since September 1991;

     WHEREAS,  the Company desires to continue to employ  Executive as President
and Chief Operating Officer of the Company, and Executive desires to accept such
employment on the terms and conditions herein set forth.

     NOW,  THEREFORE,  in consideration  of the foregoing,  the mutual covenants
contained  herein,  and other good and  valuable  consideration  the receipt and
adequacy of which the Company and Executive each hereby acknowledge, the Company
and Executive hereby agree as follows:

1.   Employment.

     The Company  hereby  agrees to employ  Executive as its President and Chief
Operating  Officer,  and Executive  hereby agrees to accept such  employment and
serve in such  capacities,  during the Term as defined in Section 2 (subject  to
Section  7(c) and  7(e)) and upon the  terms  and  conditions  set forth in this
Employment Agreement (the "Agreement").


<PAGE>

2.   Term.

     The term of employment of Executive under this Agreement (the "Term") shall
be the period  commencing on the Effective  Date and ending on June 30, 2001 and
any period of extension  thereof in accordance  with this Section 2, except that
the  Term  will  end at a date,  prior to the end of such  period  or  extension
thereof,  specified in Section 6 or 7 in the event of termination of Executive's
employment.  The Term, if not previously ended, shall be extended  automatically
without  further action by either party by one additional year (added to the end
of the Term) first on June 30, 2001 (extending the Term to June 30, 2002) and on
each  succeeding  June 30  thereafter,  unless  either  party  shall have served
written  notice in  accordance  with  Section  12(d) upon the other  party on or
before the December 31 preceding a June 30 extension date electing not to extend
the Term further as of that June 30  extension  date,  in which case  employment
shall terminate on that June 30 and the Term shall end at that date,  subject to
earlier  termination  of  employment  and  earlier  termination  of the  Term in
accordance  with  Section 6 or 7. The  foregoing  notwithstanding,  in the event
there occurs a Potential  Change in Control  during the period of 180 days prior
to the June 30 on which the Term will  terminate  as a result of notice given by
Executive hereunder, the Term shall be extended automatically at that June 30 by
an  additional  period  such  that the Term  will  extend  until  the  180th day
following such Potential Change in Control.

3.   Offices and Duties.

     The  provisions  of this  Section 3 will apply  during the Term,  except as
otherwise provided in Section 7(c) and 7(e):

          (a)  Generally.  Executive  shall  serve as the  President  and  Chief
     Operating  Officer of the Company and, if elected,  shall serve as a member
     of the Board of Directors of the Company (the  "Board") and, for so long as
     she is serving on the Board,  Executive  agrees to serve as a member of any
     Board committee if the Board shall elect  Executive to such  committee.  In
     any and all such capacities, Executive shall report only to the Chairman of
     the Board and Chief  Executive  Officer  of the  Company  and to the Board.
     Executive  shall  have  and  perform  such  duties,  responsibilities,  and
     authorities as are customary for the president and chief operating  officer
     of a publicly held corporation of the size, type, and nature of the Company
     as they may exist from time to time and  consistent  with such position and
     status,  but  in  no  event  shall  such  duties,   responsibilities,   and
     authorities  be reduced  from those of  Executive  at the  Effective  Date.
     Executive  shall devote her full business time and attention,  and her best
     efforts,  abilities,  experience, and talent, to the positions of President
     and Chief  Operating  Officer and for the businesses of the Company without
     commitment to other business endeavors,  except that Executive (i) may make
     personal  investments  which  are not in  conflict  with her  duties to the
     Company and manage  personal and family  financial and legal affairs,  (ii)
     may serve as a member of the board of  directors  of each of Orion  Capital
     Corporation and Ligand Pharmaceuticals Incorporated, (iii) undertake public
     speaking engagements,  and (iv) serve as a director of (or similar position
     with) any other business or an educational,  charitable,  community, civic,
     religious,  or similar type of organization  with the approval of the Chief
     Executive  Officer and the Board, so long as such activities  (i.e.,  those
     listed in clauses (i)  through  (iv)) do not  preclude  or render  unlawful
     Executive's  employment  or service to the Company or otherwise  materially
     inhibit the  performance  of  Executive's  duties  under this  Agreement or
     materially impair the business of the Company or its subsidiaries.


                                      -2-

     Connecticut (iv) Montgomery County,  Pennsylvania,  (v) Passaic County, New
     Jersey, or (vi) London, England.

4.   Salary and Annual Incentive Compensation.

     As partial  compensation  for the  services  to be  rendered  hereunder  by
Executive,  the  Company  agrees  to  pay  to  Executive  during  the  Term  the
compensation set forth in this Section 4.

          (a) Base Salary.  The Company will pay to Executive  during the Term a
     base salary at the  initial  annual  rate of  $600,000,  payable in cash in
     substantially equal semi-monthly  installments  commencing at the beginning
     of the Term, and otherwise in accordance  with the Company's  usual payroll
     practices with respect to senior executives  (except to the extent deferred
     under Section  5(d)).  Executive's  annual base salary shall be reviewed by
     the Compensation and Benefits  Committee of the Board (the  "Committee") at
     least once in each calendar year and may be increased above, but may not be
     reduced below, the then-current  rate of such base salary.  For purposes of
     this Agreement, "Base Salary" means Executive's then-current base salary.

          (b) Annual Incentive  Compensation.  The Company will pay to Executive
     during  the  Term  annual  incentive  compensation  which  shall  offer  to
     Executive  an  opportunity  to  earn  additional  compensation  based  upon
     performance in amounts  determined by the Committee in accordance  with the
     applicable  plan  and  consistent  with  past  practices  of  the  Company;
     provided,  however, that the annual incentive opportunity shall be not less
     than the  greater  of 58% of Base  Salary or the  annual  target  incentive
     opportunity for the prior year for achievement of target level performance,
     with the nature of the performance and the levels of performance triggering
     payments of such annual target  incentive  compensation for each year to be
     established and  communicated to Executive during the first quarter of such
     year by the  Committee.  In  addition,  the  Committee  (or the  Board) may
     determine,  in its discretion,  to increase the  Executive's  annual target
     incentive   opportunity   or  provide  an   additional   annual   incentive
     opportunity, in excess of the annual target incentive opportunity,  payable
     for performance in excess of or in addition to the performance required for
     payment  of the  annual  target  incentive  amount.  Any  annual  incentive
     compensation  payable to  Executive  shall be paid in  accordance  with the
     Company's usual practices with respect to payment of incentive compensation
     to senior executives (except to the extent deferred under Section 5(d)).

5.   Long-Term  Compensation,  Including Stock Options,  and Benefits,  Deferred
     Compensation, and Expense Reimbursement

          (a) Executive  Compensation Plans.  Executive shall be entitled during
     the Term to participate,  without  discrimination  or  duplication,  in all
     executive   compensation   plans  and   programs   intended   for   general
     participation by senior  executives of the Company,  as presently in effect
     or as they may be modified  or added to by the  Company  from time to time,


                                      -3-

     subject  to the  eligibility  and  other  requirements  of such  plans  and
     programs,  including without limitation any stock option plans, plans under
     which restricted stock/restricted stock units, performance-based restricted
     stock/restricted stock units ("PERS") or performance-accelerated restricted
     stock/restricted  stock units  ("PARS")  may be awarded,  other  annual and
     long-term cash and/or equity  incentive  plans,  and deferred  compensation
     plans;  provided,  however, that such plans and programs, in the aggregate,
     shall provide Executive with compensation and incentive award opportunities
     substantially  no less  favorable  than those  provided  by the  Company to
     Executive under such plans and programs as in effect on the Effective Date.

          (b) Employee and Executive Benefit Plans.  Executive shall be entitled
     during the Term to participate,  without discrimination or duplication,  in
     all employee and executive  benefit  plans and programs of the Company,  as
     presently  in effect or as they may be  modified or added to by the Company
     from time to time,  to the extent such plans are  available to other senior
     executives  or  employees of the Company,  subject to the  eligibility  and
     other requirements of such plans and programs, including without limitation
     plans providing  pensions,  supplemental  pensions,  supplemental and other

     insurance,  and accidental  death or  dismemberment  insurance,  as well as
     savings, profit-sharing, and stock ownership plans; provided, however, that
     such benefit plans and programs, in the aggregate,  shall provide Executive
     with benefits and  compensation  substantially no less favorable than those
     provided by the Company to  Executive  under such plans and  programs as in
     effect on the  Effective  Date.  The foregoing  notwithstanding,  Executive
     shall  not be  eligible  to  participate  or  receive  benefits  under  the
     Company's Employee Protection Plan.

     In furtherance of and not in limitation of the foregoing, during the Term:

       (i)    Executive  will  participate  as  President  and  Chief  Operating

       (ii)   The Company will provide  Executive with coverage as President and
              Chief  Operating  Officer  with  respect to  long-term  disability
              insurance and benefits  substantially no less favorable (including

              benefits in effect on the Effective Date;

       (iii)  Executive  will be covered by  Company-paid  group and  individual
              term life  insurance  providing  a death  benefit no less than the
              death benefit provided under  Company-paid  insurance in effect at
              the Effective Date; provided,  however,  that, with the consent of
              Executive,  such  insurance may be combined  with a  supplementary
              retirement funding vehicle;

       (iv)   Executive will be entitled to retirement benefits substantially no
              less favorable than those under the defined  benefit pension plans
              and programs of the Company, including the IMS Health Incorporated
              Supplemental  Executive Retirement Plan (the "SERP"), as in effect
              on the Effective Date; and

       (v)    The  Company  will  provide  Executive  with  health  and  medical
              benefits consistent

<PAGE>

              with its policies for other senior executives.

          Any   provision   to  the  contrary   contained   in  this   Agreement
     notwithstanding,  unless Executive is terminated by the Company for "Cause"
     (as defined in Section 8(a)) or Executive  terminates  voluntarily  and not
     for "Good  Reason"  (as  defined  in  Section  8(e)),  Executive  may elect
     continued  participation  after  termination of employment in the Company's
     health and  medical  coverage  for  herself  and her  spouse and  dependent
     children  after  such  coverage  would  otherwise  end  until  such time as
     Executive becomes eligible for similar coverage with a subsequent  employer
     or other entity to which Executive  provides  services or becomes  eligible
     for  Medicare  (under  rules  in  effect  at the  Effective  Date  hereof);
     provided, however, that in the event of such election,  Executive shall pay
     the Company  each year an amount  equal to the  then-current  annual  COBRA
     premium  being  paid (or  payable)  by any  other  former  employee  of the
     Company, unless otherwise provided under Section 6 or 7.

          (c) Acceleration of Awards Upon a Change in Control. In the event of a
     Change in Control  (as  defined in Section  8(b)),  all  outstanding  stock
     options and restricted stock then held by Executive shall become vested and
     exercisable.

          (d) Deferral of  Compensation.  If the Company has in effect or adopts
     any deferral program or arrangement permitting executives to elect to defer
     any compensation, Executive will be eligible to participate in such program
     on terms no less  favorable  than the terms of  participation  of any other
     executive officer of the Company.

     efforts to file with the Securities and Exchange  Commission and thereafter

     registering  under the Securities Act of 1933, as amended (the "1933 Act"),
     the offer and sale of shares by the Company to Executive  pursuant to stock
     options or other  equity-based  awards  granted to Executive  under Company
     plans or otherwise or, if shares are acquired by Executive in a transaction
     not  involving an offer or sale to Executive  but resulting in the acquired
     shares  being  "restricted  securities"  for  purposes  of  the  1933  Act,
     registering the reoffer and resale of such shares by Executive.

          (f)  Reimbursement  of Expenses.  The Company will promptly  reimburse
     Executive for all reasonable  business expenses and disbursements  incurred
     by Executive in the  performance of  Executive's  duties during the Term in
     accordance with the Company's reimbursement policies as in effect from time
     to time.

6.   Termination Due to Retirement, Death, or Disability.

          (a) Retirement.  Executive may elect to terminate employment hereunder
     by  retirement at or after age 55 or at such earlier age as may be approved
     by the  Board  (in  either  case,  "Retirement").  At the time  Executive's
     employment  terminates  due to  Retirement,  the Term will  terminate,  all
     obligations of the Company and Executive under Sections 1 through 5 of this
     Agreement will  immediately  cease except for  obligations  which expressly
     continue after termination of employment due to Retirement, and the Company

              Section 8(c));

       (ii)   In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal to the portion of annual incentive  compensation  that would
              have become  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash awards) for that year
              if  her  employment  had  not  terminated,  based  on  performance
              actually  achieved  in  that  year  (determined  by the  Committee
              following  completion of the  performance  year),  multiplied by a
              fraction the  numerator  of which is the number of days  Executive
              was employed in the year of  termination  and the  denominator  of
              which is the total number of days in the year of termination;

       (iii)  The vesting and  exercisability of stock options held by Executive
              at  termination  and all  other  terms  of such  options  shall be
              governed by the plans and  programs and the  agreements  and other
              documents  pursuant to which such options were granted (subject to
              Section 10(f) hereof); and

       (iv)   All  restricted   stock  and  deferred  stock  awards,   including
              outstanding PERS awards, all other long-term incentive awards, and
              all deferral arrangements under Section 5(d), shall be governed by
              the plans and  programs  under  which the awards  were  granted or
              governing  the  deferral,  and all  rights  under the SERP and any
              other benefit plan shall be governed by such plan.

          (b) Death.  In the event of  Executive's  death  which  results in the
     termination  of  Executive's  employment,  the  Term  will  terminate,  all
     obligations of the Company and Executive under Sections 1 through 5 of this
     Agreement will  immediately  cease except for  obligations  which expressly
     continue after death,  and the Company will pay Executive's  beneficiary or
     estate, and Executive's  beneficiary or estate will be entitled to receive,
     the following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's death occurred,  an amount equal
              to the portion of annual  incentive  compensation  that would have
              become payable in cash to Executive  (i.e.,  excluding the portion
              payable in PERS or in other non-cash  awards) for that year if her
              employment  had not  terminated,  based  on  performance  actually
              achieved  in that  year  (determined  by the  Committee  following
              completion of the performance year),  multiplied by a fraction the
              numerator of which is the number of days Executive was employed in
              the year of her  death and the  denominator  of which is the total
              number of days in the year of death;

       (iii)  The vesting and  exercisability of stock options held by Executive
              at death and all other terms of such options  shall be governed by
              the plans and programs and

                                      -6-
<PAGE>

              the agreements and other documents  pursuant to which such options
              were granted; and

              outstanding PERS awards, all other long-term incentive awards, and

              the plans and  programs  under  which the awards  were  granted or
              governing  the  deferral,  and all  rights  under the SERP and any
              other benefit plan shall be governed by such plan.

          (c) Disability.  The Company may terminate the employment of Executive
     hereunder due to the  Disability (as defined in Section 8(d)) of Executive.
     Such  employment  shall  terminate at the  expiration  of the 30-day period
     referred to in the  definition  of  Disability  set forth in Section  8(d),
     unless  Executive  has  returned to service and  presented to the Company a
     certificate  of good  health  prior to such  termination  as  specified  in
     Section 8(d). Upon termination of employment,  the Term will terminate, all
     obligations of the Company and Executive under Sections 1 through 5 of this
     Agreement will  immediately  cease except for  obligations  which expressly
     continue after termination of employment due to Disability, and the Company
     will  pay  Executive,  and  Executive  will be  entitled  to  receive,  the
     following:

       (i)    Executive's Compensation Accrued at Termination;

              portion payable in PERS or in other non-cash awards) for that year

              actually  achieved  in  that  year  (determined  by the  Committee
              following  completion of the  performance  year),  multiplied by a
              fraction the  numerator  of which is the number of days  Executive
              was employed in the year of  termination  and the  denominator  of
              which is the total number of days in the year of termination;

       (iii)  Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such  termination,  and, in other respects  (including the
              period  following  termination  during  which such  options may be
              exercised),  such  options  shall be  governed  by the  plans  and
              programs and the agreements and other documents  pursuant to which
              such options were granted;

       (iv)   Any   performance   objectives   upon   which   the   earning   of

              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and non-forfeitable at the



                                      -7-
<PAGE>

              date of such  termination,  and,  in other  respects,  such awards

              shall  continue to  participate  in those  employee and  executive
              benefit  plans and programs  under Section 5(b) to the extent such
              plans and programs provide medical insurance, disability insurance
              and life  insurance  benefits  (but not  other  benefits,  such as
              pension and retirement  benefits,  provided under Section 5(b)) in
              which   Executive   was   participating   immediately   prior   to
              termination,  the  terms  of  which  allow  Executive's  continued
              participation,  as if Executive had  continued in employment  with
              the  Company  during such period or, if the terms of such plans or
              programs  do  not  allow  Executive's   continued   participation,
              Executive shall be paid a cash payment  equivalent on an after-tax
              basis  to the  value  of the  additional  benefits  (of  the  type
              described in this Section 6(c)(vi))  Executive would have received
              under  such  plans  or  programs  had  Executive  continued  to be
              employed  during such  period  following  Executive's  termination
              until age 65,  with such  benefits  provided by the Company at the
              same times and in the same manner as such benefits would have been
              provided  to  Executive  under such plans and  programs  (it being
              understood that the value of any insurance-provided  benefits will
              be based on the premium cost to Executive,  which shall not exceed
              the highest risk premium charged by a carrier having an investment
              grade or better credit rating); provided,  however, that Executive
              must continue to satisfy the conditions set forth in Section 10 in
              order to  continue  receiving  the  benefits  provided  under this
              Section 6(c)(vi).

          (d) Other Terms of Payment Following Retirement, Death, or Disability.
     Nothing in this Section 6 shall limit the  benefits  payable or provided In
     the event Executive's  employment  terminates due to Retirement,  death, or
     Disability  under  the  terms of  plans or  programs  of the  Company  more
     favorable to the Executive (or her beneficiaries) than the benefits payable
     or provided  under this Section 6 (except in the case of annual  incentives
     in lieu of which amounts are paid hereunder),  including plans and programs
     adopted  after  the date of this  Agreement.  Amounts  payable  under  this
     Section 6 following Executive's termination of employment, other than those
     expressly  payable  following  determination of performance for the year of
     termination  for  purposes of annual  incentive  compensation  or otherwise
     expressly  payable  on a  deferred  basis,  will  be paid  as  promptly  as
     practicable after such termination of employment.

     Disability.

     terminate her employment hereunder  voluntarily for reasons other than Good
     Reason (as defined in Section  8(e)) at any time.  An election by Executive

              programs under which the awards were granted; and

       (iii)  All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral, and

              governed by such plan.

     Years After a Change in Control.  The Company may terminate the  employment
     of Executive  hereunder  without  Cause,  if at the date of  termination no
     Change in Control has occurred or such date of  termination is at least two
     years  after  the most  recent  Change in  Control,  upon at least 90 days'
     written notice to Executive. The foregoing notwithstanding, the Company may

     elect, by written notice to Executive,  to terminate  Executive's positions
     specified in Sections 1 and 3 and all other  obligations  of Executive  and
     the Company under  Section 3 at a date earlier than the  expiration of such
     90-day  period,  if so  specified  by the  Company in the  written  notice,
     provided  that  Executive  shall be treated as an  employee  of the Company
     (without any  assigned  duties) for all other  purposes of this  Agreement,
     including for purposes of Sections 4 and 5, from such  specified date until
     the  expiration  of such 90-day  period.  An election by the Company not to
     extend  the Term  pursuant  to  Section  2 hereof  shall be  deemed to be a
     termination of Executive's  employment by the Company  without Cause at the
     date of expiration of the Term and shall be subject to this Section 7(c) if
     at the date of such  termination  no Change in Control has occurred or such
     date of  termination  is at least two years after the most recent Change in
     Control; provided,  however, that, if Executive has attained age 65 at such
     date of  termination,  such  termination  shall be deemed a  Retirement  of
     Executive.  At the time Executive's employment is terminated by the Company
     (i.e., at the expiration of such notice  period),  the Term will terminate,
     all remaining  obligations  of the Company and Executive  under  Sections 1
     through 5 of this  Agreement  will  immediately  cease (except as expressly
     provided below), and the Company will pay Executive,  and Executive will be
     entitled to receive, the following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   Cash in an  aggregate  amount  equal to two  times  the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined  to be payable  under this  Section  7(c)(ii)  shall be
              payable  in  monthly  installments  over the 24  months  following
              termination,  without  interest,  except the  Company may elect to
              accelerate  payment of the remaining balance of such amount and to
              pay it as a lump sum, without discount;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal  to the  portion  of  Executive's  annual  target  incentive
              compensation  potentially  payable  in  cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for  the  year  of  termination,  multiplied  by  a  fraction  the
              numerator of which is the number of days Executive was employed in
              the year of termination  and the denominator of which is the total
              number of days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such  termination,  and, in other respects  (including the
              period following termination


                                      -10-
<PAGE>

              during which such options may be exercised), such options shall be
              governed by the plans and  programs and the  agreements  and other
              documents pursuant to which such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,
              and, in other respects, such awards shall be governed by the plans
              and programs and the  agreements and other  documents  pursuant to
              which such awards were granted;

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For  purposes  of the  SERP,  Executive  shall  be  credited  with
              additional years of age and/or years of Service (as defined in the
              SERP)  if  and  to  the  extent   required  so  that   Executive's
              termination  will qualify as a "Retirement"  within the meaning of
              the SERP, so that  Executive will be entitled to not less than the
              minimum "Retirement Benefit" determined in accordance with Section
              3.1 of the SERP.

       (viii) For a period of two years  after such  termination  (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive  provides  services  during such period  providing
              comparable  benefits.  If the  terms  of  the  Company  plans  and
              programs  referred  to in this  Section  7(c)(viii)  do not  allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional benefits described in this Section 7(c)(viii) Executive
              would have  received  under such plans or programs  had  Executive
              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would have been provided to Executive  under such
              plans  and  programs  (it being  understood  that the value of any
              insurance-provided benefits will be based on



                                      -11-
<PAGE>

              the premium cost to Executive,  which shall not exceed the highest
              risk premium  charged by a carrier  having an investment  grade or
              better credit  rating);  provided,  however,  that  Executive must
              continue  to  satisfy  the  conditions  set forth in Section 10 in
              order to  continue  receiving  the  benefits  provided  under this
              Section  7(c)(viii).  Executive  agrees  to  promptly  notify  the
              Company of any employment or other  arrangement by which Executive
              provides services during the  benefits-continuation  period and of
              the nature  and extent of  benefits  for which  Executive  becomes
              eligible  during  such  period  which  would  reduce or  terminate
              benefits  under  this  Section  7(c)(viii);  and  the  Company  be
              entitled  to recover  from  Executive  any  payments  and the fair
              market value of benefits  previously made or provided to Executive
              hereunder  which  would  not have  been paid  under  this  Section
              7(c)(viii)  if the Company had received  adequate  prior notice as
              required by this sentence.

          (d) Termination by Executive for Good Reason Prior to or More than Two
     Years After a Change in Control.  Executive may  terminate  her  employment
     hereunder for Good Reason, prior to a Change in Control or after the second
     anniversary  of the most recent  Change in Control,  upon 90 days'  written
     notice  to  the  Company;  provided,  however,  that,  if the  Company  has
     corrected  the basis for such Good Reason  within 30 days after  receipt of
     such notice,  Executive may not terminate her  employment  for Good Reason,
     and therefore  Executive's notice of termination will automatically  become
     null  and  void.  At the  time  Executive's  employment  is  terminated  by
     Executive for Good Reason (i.e.,  at the expiration of such notice period),
     the Term will terminate, all obligations of the Company and Executive under
     Sections 1 through 5 of this  Agreement will  immediately  cease (except as
     expressly  provided  below),  and  the  Company  will  pay  Executive,  and
     Executive will be entitled to receive, the following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   Cash in an  aggregate  amount  equal to two  times  the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined  to be payable  under this  Section  7(d)(ii)  shall be
              payable  in  monthly  installments  over the 24  months  following
              termination,  without  interest,  except the  Company may elect to
              accelerate  payment of the remaining balance of such amount and to
              pay it as a lump sum, without discount;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal  to the  portion  of  Executive's  annual  target  incentive
              compensation potentially payable in cash to


                                      -12-
<PAGE>

              Executive (i.e., excluding the portion payable in PERS or in other
              non-cash  awards)  for the year of  termination,  multiplied  by a
              fraction the  numerator  of which is the number of days  Executive
              was employed in the year of  termination  and the  denominator  of
              which is the total number of days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such  termination,  and, in other respects  (including the
              period  following  termination  during  which such  options may be
              exercised),  such  options  shall be  governed  by the  plans  and
              programs and the agreements and other documents  pursuant to which
              such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,
              and, in other respects, such awards shall be governed by the plans
              and programs and the  agreements and other  documents  pursuant to
              which such awards were granted;

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For  purposes  of the  SERP,  Executive  shall  be  credited  with
              additional years of age and/or years of Service (as defined in the
              SERP)  if  and  to  the  extent   required  so  that   Executive's
              termination  will qualify as a "Retirement"  within the meaning of
              the SERP, so that  Executive will be entitled to not less than the
              minimum "Retirement Benefit" determined in accordance with Section
              3.1 of the SERP.

       (viii) For a period of two years  after such  termination  (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive provides services during such period

                                      -13-
<PAGE>

              providing comparable  benefits.  If the terms of the Company plans
              and programs  referred to in this Section  7(d)(viii) do not allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional benefits described in this Section 7(d)(viii) Executive
              would have  received  under such plans or programs  had  Executive
              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would have been provided to Executive  under such
              plans  and  programs  (it being  understood  that the value of any
              insurance-provided  benefits  will be based on the premium cost to
              Executive, which shall not exceed the highest risk premium charged
              by a carrier having an investment  grade or better credit rating);
              provided,  however,  that  Executive  must continue to satisfy the
              conditions set forth in Section 10 in order to continue  receiving
              the benefits  provided  under this Section  7(d)(viii).  Executive
              agrees to promptly  notify the Company of any  employment or other
              arrangement  by  which  Executive  provides  services  during  the
              benefits-continuation  period  and of the  nature  and  extent  of
              benefits for which Executive  becomes  eligible during such period
              which  would  reduce or  terminate  benefits  under  this  Section
              7(d)(viii);  and the Company  shall be  entitled  to recover  from
              Executive  any  payments  and the fair  market  value of  benefits
              previously made or provided to Executive hereunder which would not
              have been paid under this  Section  7(d)(viii)  if the Company had
              received adequate prior notice as required by this sentence.

If any  payment or benefit  under this  Section  7(d) is based on Base Salary or
other level of compensation  or benefits at the time of Executive's  termination
and if a reduction in such Base Salary or other level of compensation or benefit
was the basis for Executive's  termination for Good Reason, then the Base Salary
or other level of  compensation in effect before such reduction shall be used to
calculate payments or benefits under this Section 7(d).

          (e)  Termination by the Company Without Cause Within Two Years After a
     Change in Control.  The Company may terminate  the  employment of Executive
     hereunder  without Cause,  simultaneously  with or within two years after a
     Change in Control, upon at least 90 days' written notice to Executive.  The
     foregoing  notwithstanding,  the  Company may elect,  by written  notice to
     Executive, to terminate Executive's positions specified in Sections 1 and 3
     and all other obligations of Executive and the Company under Section 3 at a
     date  earlier  than the  expiration  of such 90-day  notice  period,  if so
     specified by the Company in the written  notice,  provided  that  Executive
     shall be  treated as an  employee  of the  Company  (without  any  assigned
     duties) for all other purposes of this Agreement, including for purposes of
     Sections 4 and 5, from such  specified  date until the  expiration  of such
     90-day  period.  An election by the Company not to extend the Term pursuant
     to  Section 2 hereof  shall be deemed to be a  termination  of  Executive's
     employment  by the Company  without  Cause at the date of expiration of the
     Term  and  shall  be  subject  to this  Section  7(e)  if the  date of such
     termination  coincides  with or is  within  two  years  after a  Change  in
     Control; provided,  however, that, if Executive has attained age 65 at such
     date of  termination,  such  termination  shall be deemed a  Retirement  of
     Executive.  At the time Executive's employment is terminated by the Company
     (i.e., at the expiration of such notice  period),  the Term will terminate,
     all remaining  obligations  of the 


                                      -14-
<PAGE>

     Company and Executive  under  Sections 1 through 5 of this  Agreement  will
     immediately  cease (except as expressly  provided  below),  and the Company
     will  pay  Executive,  and  Executive  will be  entitled  to  receive,  the
     following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   Cash in an  aggregate  amount  equal to three times the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined to be payable under this Section 7(e)(ii) shall be paid
              by  the  Company   not  later  than  15  days  after   Executive's
              termination;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal  to the  portion  of  Executive's  annual  target  incentive
              compensation  potentially  payable  in  cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for  the  year  of  termination,  multiplied  by  a  fraction  the
              numerator of which is the number of days Executive was employed in
              the year of termination  and the denominator of which is the total
              number of days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such termination, and any such options granted on or after
              the date hereof shall remain outstanding and exercisable until the
              stated  expiration  date  of  the  Option  as  though  Executive's
              employment did not terminate, and, in other respects, such options
              shall be governed by the plans and programs and the agreements and
              other documents pursuant to which such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term incentive awards (to the extent then or previously
              earned,  in the case of  performance-based  awards)  shall  become
              fully vested and  non-forfeitable at the date of such termination,
              and, in other respects, such awards shall be governed by the plans
              and programs and the  agreements and other  documents  pursuant to
              which such awards were granted;

                                      -15-
<PAGE>

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For  purposes  of the  SERP,  Executive  shall  be  credited  with
              additional years of age and/or years of Service (as defined in the
              SERP)  if  and  to  the  extent   required  so  that   Executive's
              termination  will qualify as a "Retirement"  within the meaning of
              the  SERP  and so that  Executive  will be  entitled  the  maximum
              "Retirement Benefit" in accordance with Section 3.1 of the SERP.

       (viii) For a period of three years after such  termination (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive  provides  services  during such period  providing
              comparable  benefits.  If the  terms  of  the  Company  plans  and
              programs  referred  to in this  Section  7(e)(viii)  do not  allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional benefits described in this Section 7(e)(viii) Executive
              would have  received  under such plans or programs  had  Executive
              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would have been provided to Executive  under such
              plans  and  programs  (it being  understood  that the value of any
              insurance-provided  benefits  will be based on the premium cost to
              Executive, which shall not exceed the highest risk premium charged
              by a carrier having an investment  grade or better credit rating);
              provided,  however,  that  Executive  must continue to satisfy the
              conditions set forth in Section 10 in order to continue  receiving
              the benefits  provided  under this Section  7(e)(viii).  Executive
              agrees to promptly  notify the Company of any  employment or other
              arrangement  by  which  Executive  provides  services  during  the
              benefits-continuation  period  and of the  nature  and  extent  of
              benefits for which Executive  becomes  eligible during such period
              which  would  reduce or  terminate  benefits  under  this  Section
              7(e)(viii);  and the Company  shall be  entitled  to recover  from
              Executive  any  payments  and the fair  market  value of  benefits
              previously made or provided to Executive hereunder which would not
              have been paid under this  Section  7(e)(viii)  if the Company had
              received adequate prior notice as required by this sentence.

          (f)  Termination by Executive for Good Reason Within Two Years After a
     Change in Control.  Executive may terminate  her  employment  hereunder for
     Good  Reason,  


                                      -16-
<PAGE>

     simultaneously with or within two years after a Change in Control,  upon 90
     days'  written  notice to the  Company;  provided,  however,  that,  if the
     Company has  corrected  the basis for such Good Reason within 30 days after
     receipt of such notice, Executive may not terminate her employment for Good
     Reason, and therefore  Executive's notice of termination will automatically
     become null and void. At the time  Executive's  employment is terminated by
     Executive for Good Reason (i.e.,  at the expiration of such notice period),
     the Term will terminate, all obligations of the Company and Executive under
     Sections 1 through 5 of this  Agreement will  immediately  cease (except as
     expressly  provided  below),  and  the  Company  will  pay  Executive,  and
     Executive will be entitled to receive, the following:

       (i)    Executive's Compensation Accrued at Termination;

       (ii)   Cash in an  aggregate  amount  equal to three times the sum of (A)
              Executive's  Base Salary under Section 4(a)  immediately  prior to
              termination  plus (B) an amount  equal to the  greater  of (x) the
              portion  of  Executive's  annual  target  incentive   compensation
              potentially  payable in cash to  Executive  (i.e.,  excluding  the
              portion payable in PERS or in other non-cash  awards) for the year
              of termination or (y) the portion of Executive's  annual incentive
              compensation  that  became  payable  in cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for the latest year  preceding  the year of  termination  based on
              performance  actually  achieved  in that latest  year.  The amount
              determined to be payable under this Section 7(f)(ii) shall be paid
              by  the  Company   not  later  than  15  days  after   Executive's
              termination;

       (iii)  In lieu of any annual  incentive  compensation  under Section 4(b)
              for the year in which Executive's employment terminated, an amount
              equal  to the  portion  of  Executive's  annual  target  incentive
              compensation  potentially  payable  in  cash to  Executive  (i.e.,
              excluding the portion payable in PERS or in other non-cash awards)
              for  the  year  of  termination,  multiplied  by  a  fraction  the
              numerator of which is the number of days Executive was employed in
              the year of termination  and the denominator of which is the total
              number of days in the year of termination;

       (iv)   Stock options held by Executive at termination, if not then vested
              and  exercisable,  will become fully vested and exercisable at the
              date of such termination, and any such options granted on or after
              the date hereof shall remain outstanding and exercisable until the
              stated  expiration  date  of  the  Option  as  though  Executive's
              employment did not terminate, and, in other respects, such options
              shall be governed by the plans and programs and the agreements and
              other documents pursuant to which such options were granted;

       (v)    Any   performance   objectives   upon   which   the   earning   of
              performance-based  restricted  stock and  deferred  stock  awards,
              including  outstanding PERS awards, and other long-term  incentive
              awards is  conditioned  shall be deemed to have been met at target
              level  at the  date  of  termination,  and  restricted  stock  and
              deferred  stock awards,  including  outstanding  PERS awards,  and
              other long-term

                                      -17-

<PAGE>

              incentive awards (to the extent then or previously  earned, in the
              case of  performance-based  awards)  shall become fully vested and
              non-forfeitable  at the date of such  termination,  and,  in other
              respects,  such awards shall be governed by the plans and programs
              and the  agreements  and other  documents  pursuant  to which such
              awards were granted;

       (vi)   All deferral  arrangements  under  Section 5(d) will be settled in
              accordance with the plans and programs governing the deferral;

       (vii)  For  purposes  of the  SERP,  Executive  shall  be  credited  with
              additional years of age and/or years of Service (as defined in the
              SERP)  if  and  to  the  extent   required  so  that   Executive's
              termination  will qualify as a "Retirement"  within the meaning of
              the  SERP  and so that  Executive  will be  entitled  the  maximum
              "Retirement Benefit" in accordance with Section 3.1 of the SERP.

       (viii) For a period of three years after such  termination (but not after
              Executive attains age 65), Executive shall continue to participate
              in those  employee and executive  benefit plans and programs under
              Section 5(b) to the extent such plans and programs provide medical
              insurance,  disability  insurance and life insurance benefits (but
              not other  benefits,  such as  pension  and  retirement  benefits,
              provided under Section 5(b)) in which Executive was  participating
              immediately  prior  to  termination,  the  terms  of  which  allow
              Executive's continued participation, as if Executive had continued
              in  employment  with the  Company  during such  period;  provided,
              however, that such participation shall terminate,  or the benefits
              under  such plans and  programs  shall be  reduced,  if and to the
              extent  Executive  becomes  covered  (or  is  eligible  to  become
              covered)  by plans of a  subsequent  employer  or other  entity to
              which Executive  provides  services  during such period  providing
              comparable  benefits.  If the  terms  of  the  Company  plans  and
              programs  referred  to in this  Section  7(f)(viii)  do not  allow
              Executive's  continued  participation,  Executive  shall be paid a
              cash payment  equivalent on an after-tax basis to the value of the
              additional benefits described in this Section 7(f)(viii) Executive
              would have  received  under such plans or programs  had  Executive
              continued to be employed  during such period,  with such  benefits
              provided  by the  Company at the same times and in the same manner
              as such benefits would have been provided to Executive  under such
              plans  and  programs  (it being  understood  that the value of any
              insurance-provided  benefits  will be based on the premium cost to
              Executive, which shall not exceed the highest risk premium charged
              by a carrier having an investment  grade or better credit rating);
              provided,  however,  that  Executive  must continue to satisfy the
              conditions set forth in Section 10 in order to continue  receiving
              the benefits  provided  under this Section  7(f)(viii).  Executive
              agrees to promptly  notify the Company of any  employment or other
              arrangement  by  which  Executive  provides  services  during  the
              benefits-continuation  period  and of the  nature  and  extent  of
              benefits for which Executive  becomes  eligible during such period
              which  would  reduce or  terminate  benefits  under  this  Section
              7(f)(viii);  and the Company  shall be  entitled  to recover  from
              Executive any payments and the fair market value of benefits


                                      -18-
<PAGE>

              previously made or provided to Executive hereunder which would not
              have been paid under this  Section  7(f)(viii)  if the Company had
              received adequate prior notice as required by this sentence.

If any  payment or benefit  under this  Section  7(f) is based on Base Salary or
other level of compensation  or benefits at the time of Executive's  termination
and if a reduction in such Base Salary or other level of compensation or benefit
was the basis for Executive's  termination for Good Reason, then the Base Salary
or other level of  compensation in effect before such reduction shall be used to
calculate payments or benefits under this Section 7(f).

          (g) Other  Terms  Relating  to  Certain  Terminations  of  Employment.
     Whether a termination is deemed to be at or within two years after a Change
     in Control for purposes of Sections 7(c), (d), (e), or (f) is determined at
     the date of  termination,  regardless  of whether the Change in Control had
     occurred  at the time a notice  of  termination  was  given.  In the  event
     Executive's  employment terminates for any reason set forth in Section 7(b)
     through  (f),  Executive  will be  entitled  to the benefit of any terms of
     plans or agreements  applicable to Executive  which are more favorable than
     those specified in this Section 7 (except in the case of annual  incentives
     in lieu of which amounts are paid  hereunder).  Amounts  payable under this
     Section 7 following Executive's termination of employment, other than those
     expressly  payable  on a  deferred  basis,  will  be paid  as  promptly  as
     practicable  after  such a  termination  of  employment,  and such  amounts
     payable  under  Section 7(e) or 7(f) will be paid in no event later than 15
     days after  Executive's  termination of employment  unless not determinable
     within such period.

8.   Definitions Relating to Termination Events.

          (a)  "Cause."  For  purposes  of this  Agreement,  "Cause"  shall mean
     Executive's

     (i)  willful  and  continued  failure to  substantially  perform her duties
          hereunder  (other than any such failure  resulting from incapacity due
          to physical or mental  illness or  disability or any failure after the
          issuance of a notice of  termination  by  Executive  for Good  Reason)
          which failure is demonstrably and materially damaging to the financial
          condition or reputation of the Company  and/or its  subsidiaries,  and
          which failure  continues more than 48 hours after a written demand for
          substantial  performance is delivered to Executive by the Board, which
          demand specifically  identifies the manner in which the Board believes
          that Executive has not  substantially  performed her duties  hereunder
          and the demonstrable and material damage caused thereby; or

     (ii) the willful engaging by Executive in conduct which is demonstrably and
          materially injurious to the Company, monetarily or otherwise.

No act, or failure to act, on the part of  Executive  shall be deemed  "willful"
unless done,  or omitted to be done,  by Executive not in good faith and without
reasonable  belief that her action or omission  was in the best  interest of the
Company.  Notwithstanding  the foregoing,  Executive 


                                      -19-
<PAGE>

shall not be deemed to have been  terminated  for Cause  unless and until  there
shall have been delivered to Executive a copy of the resolution  duly adopted by
the  affirmative  vote of not  less  than  three-quarters  (3/4)  of the  entire
membership  of the Board at a meeting of the Board (after  reasonable  notice to
Executive and an opportunity for Executive,  together with Executive's  counsel,
to be heard before the Board)  finding  that,  in the good faith  opinion of the
Board,  Executive was guilty of conduct set forth above in this  definition  and
specifying the particulars thereof in detail.

          (b) "Change in Control." For purposes of this Agreement,  a "Change in
     Control"  shall be  deemed to have  occurred  if,  during  the term of this
     Agreement:

       (i)    any  "Person," as such term is used for purposes of Section  13(d)
              or 14(d) of the  Securities  Exchange Act of 1934, as amended (the
              "Exchange  Act")  (other  than the  Company,  any trustee or other
              fiduciary holding securities under an employee benefit plan of the
              Company,  or any company  owned,  directly or  indirectly,  by the
              stockholders of the Company in substantially  the same proportions
              as  their  ownership  of  stock  of  the  Company),   becomes  the
              "Beneficial  Owner" (as defined in Rule 13d-3  under the  Exchange
              Act),  directly  or  indirectly,  of  securities  of  the  Company
              representing  20% or  more of the  combined  voting  power  of the
              Company's then-outstanding securities;

       (ii)   during any period of twenty-four  months (not including any period
              prior to the effectiveness of this Agreement),  individuals who at
              the  beginning of such period  constitute  the Board,  and any new
              director (other than (A) a director  nominated by a Person who has
              entered into an agreement with the Company to effect a transaction
              described  in  Sections  (8)(b)(i),  (iii) or (iv)  hereof,  (B) a
              director  nominated  by any Person  (including  the  Company)  who
              publicly  announces  an  intention  to take or to consider  taking
              actions  (including,  but not limited to, an actual or  threatened
              proxy contest) which if consummated  would  constitute a Change in
              Control  or (C) a  director  nominated  by any  Person  who is the
              Beneficial  Owner,  directly or  indirectly,  of securities of the
              Company  representing  10% or more of the combined voting power of
              the  Company's   securities)   whose  election  by  the  Board  or
              nomination for election by the Company's stockholders was approved
              in advance by a vote of at least two-thirds (2/3) of the directors
              then still in office who either were directors at the beginning of
              the  period or whose  election  or  nomination  for  election  was
              previously  so  approved,  cease for any reason to  constitute  at
              least a majority thereof;

       (iii)  the  stockholders of the Company approve any transaction or series
              of transactions  under which the Company is merged or consolidated
              with any other company,  other than a merger or consolidation  (A)
              which  would  result  in the  voting  securities  of  the  Company
              outstanding  immediately  prior  thereto  continuing  to represent
              (either by remaining outstanding or by being converted into voting
              securities  of the  surviving  entity)  more  than  66 2/3% of the
              combined  voting power of the voting  securities of the Company or
              such surviving entity outstanding immediately after such merger or
              consolidation and (B) after which


                                      -20-
<PAGE>

              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 adopts a resolution to the effect that,  for purposes of
              this Agreement, a Change in Control has occurred.

          (c)  "Compensation  Accrued  at  Termination."  For  purposes  of this
     Agreement, "Compensation Accrued at Termination" means the following:

       (i)    The unpaid  portion of annual base salary at the rate payable,  in
              accordance  with Section 4(a) hereof,  at the date of  Executive's
              termination  of  employment,   pro  rated  through  such  date  of
              termination,  payable in accordance with the Company's regular pay
              schedule;

       (ii)   All vested, nonforfeitable amounts owing or accrued at the date of
              Executive's  termination of employment  under any compensation and
              benefit plans, programs, and arrangements set forth or referred to
              in Sections  4(b) and 5(a) and 5(b) hereof  (including  any earned
              and vested annual incentive  compensation and long-term  incentive
              award) in which  Executive  theretofore  participated,  payable in
              accordance  with the terms and conditions of the plans,  programs,
              and  arrangements   (and  agreements  and  documents   thereunder)
              pursuant to which such  compensation  and benefits were granted or
              accrued; and

       (iii)  Reasonable   business  expenses  and  disbursements   incurred  by
              Executive  prior to Executive's  termination of employment,  to be
              reimbursed  to  Executive,  as  authorized  under Section 5(f), in
              accordance  the Company's  reimbursement  policies as in effect at
              the date of such termination.

          (d) "Disability." For purposes of this Agreement,  "Disability"  means
     Executive's  absence from the full-time  performance of Executive's  duties
     hereunder for six  consecutive  months as a result of her incapacity due to
     physical or mental illness or disability, and, within 30 days after written
     notice of termination is thereafter  given by the Company,  Executive shall
     have not returned to the full-time performance of such duties.

          (e) "Good Reason." For purposes of this Agreement, "Good Reason" shall
     mean, without Executive's express written consent, the occurrence of any of
     the following  circumstances  unless, in the case of subsections (i), (iv),
     (vi) or (viii) hereof,  such circumstances are fully corrected prior to the
     date of termination specified in the notice of termination given in respect
     thereof:

       (i)    the   assignment   to  Executive  of  duties   inconsistent   with
              Executive's  position  and  status  hereunder,  or an  alteration,
              adverse to Executive, in the nature of


                                      -21-
<PAGE>

              Executive's duties, responsibilities, and authorities, Executive's
              positions or the conditions of Executive's  employment  from those
              specified  in  Section  3  or  otherwise   hereunder  (other  than
              inadvertent  actions  which  are  promptly  remedied);   for  this
              purpose,  it shall  constitute "Good Reason" under this subsection
              (e)(i) if (A)  Executive  shall be  required to report to and take
              direction  from any person or body other than the  Chairman of the
              Board and Chief  Executive  Officer of the  Company and the Board;
              and (B) if  Executive  shall be removed from the Board or from any
              Board  committee on which Executive has served during the Term, or
              there occurs any failure of Executive to be nominated, reappointed
              or  reelected as a member of the Board or as a member of any Board
              committee  on which she has served  during the Term,  including  a
              failure  of  the  Board  or  stockholders  to  take  such  actions
              (notwithstanding their legal right to do so), except the foregoing
              shall not constitute  Good Reason if occurring in connection  with
              the termination of Executive's  employment for Cause,  Disability,
              Retirement,  as a result of Executive's  death,  or as a result of
              action by or with the consent of  Executive;  for purposes of this
              Section  8(e)(i),  references  to the  Company  (and the Board and
              stockholders  of the Company) refer to the ultimate parent company
              (and its board and stockholders)  succeeding the Company following
              an  acquisition  in which the  corporate  existence of the Company
              continues, in accordance with Section 12(b);

       (ii)   (A) a reduction by the Company in Executive's Base Salary, (B) the
              setting of  Executive's  annual target  incentive  opportunity  or
              payment of earned annual  incentive in amounts less than specified
              under or otherwise not in conformity with Section 4 hereof,  (C) a
              change in  compensation or benefits not in conformity with Section
              5, or (D) a  reduction,  after a Change in Control in  perquisites
              from the level of such perquisites as in effect  immediately prior
              to the Change in  Control  or as the same may have been  increased
              from  time  to  time  after  the  Change  in  Control  except  for
              across-the-board  perquisite  reductions  similarly  affecting all
              senior  executives of the Company and all senior executives of any
              Person in control of the Company;

       (iii)  the relocation of the principle  place of  Executive's  employment
              not in  conformity  with Section 3(b)  hereof;  for this  purpose,
              required  travel on the Company's  business will not  constitute a
              relocation  so long as the extent of such travel is  substantially
              consistent with Executive's  customary business travel obligations
              in periods prior to the Effective Date;

       (iv)   the  failure by the  Company to pay to  Executive  any  portion of
              Executive's  compensation or to pay to Executive any portion of an
              installment   of   deferred   compensation   under  any   deferred
              compensation  program of the Company within seven days of the date
              such compensation is due;

       (v)    the  failure by the  Company to  continue  in effect any  material
              compensation  or  benefit  plan in  which  Executive  participated
              immediately  prior to a Change in  Control,  unless  an  equitable
              arrangement (embodied in an ongoing substitute or


                                      -22-
<PAGE>

              alternative  plan) has been made with respect to such plan, or the
              failure  by the  Company  to  continue  Executive's  participation
              therein (or in such substitute or alternative plan) on a basis not
              materially  less  favorable,  both  in  terms  of the  amounts  of
              benefits  provided  and the  level  of  Executive's  participation
              relative  to other  participants,  as  existed  at the time of the
              Change in Control;

       (vi)   the failure of the Company to obtain a satisfactory agreement from
              any  successor  to the  Company  to  fully  assume  the  Company's
              obligations and to perform under this  Agreement,  as contemplated
              in  Section  12(b)  hereof,  in a form  reasonably  acceptable  to
              Executive;

       (vii)  any  election  by the  Company  not to  extend  the  Term  of this
              Agreement  at the next  possible  extension  date under  Section 2
              hereof,  unless  Executive  will have attained age 65 at or before
              such extension date; or

       (viii) any  other   failure  by  the  Company  to  perform  any  material
              obligation  under,  or  breach  by the  Company  of  any  material
              provision of, this Agreement.

          (f) "Potential  Change in Control" For purposes of this  Agreement,  a
     "Change in Control" shall be deemed to have occurred if, during the term of
     this Agreement:

       (i)    the Company enters into an agreement,  the  consummation  of which
              would result in the occurrence of a Change in Control;

       (ii)   any Person (including the Company) publicly announces an intention
              to take or to consider  taking actions which if consummated  would
              constitute a Change in Control; or

       (iii)  the Board adopts a resolution to the effect that,  for purposes of
              this Agreement, a Potential Change in Control has occurred.

9.   Rabbi Trust Obligation Upon Potential Change in Control; Excise Tax-Related
     Provisions.

          (a) Rabbi Trust Funded Upon Potential Change in Control.  In the event
     of a Potential Change in Control, the Company shall, not later than 15 days
     thereafter,  have  established  one or more rabbi trusts and shall  deposit
     therein  cash in an amount  sufficient  to provide for full  payment of all
     potential obligations of the Company that would arise assuming consummation
     of a  Change  in  Control  and  a  subsequent  termination  of  Executive's
     employment  under  Section  7(e) or  7(f).  Such  rabbi  trust(s)  shall be
     irrevocable  and  shall  provide  that the  Company  may not,  directly  or
     indirectly,  use or recover any assets of the  trust(s)  until such time as
     all obligations  which  potentially could arise hereunder have been settled
     and paid in full, subject only to the claims of creditors of the Company in
     the event of insolvency or  bankruptcy of the Company;  provided,  however,
     that if no Change in  Control  has  occurred  within  two years  after such
     Potential  Change in Control,  such rabbi trust(s) shall at the end of such
     two-year  period  become  revocable  and may  thereafter  be revoked by the
     Company.

          (b) Gross-up If Excise Tax Would Apply. In the event Executive becomes
     entitled to any amounts  payable in connection  with a Change in Control or
     other change in control  (whether or not such amounts are payable  pursuant
     to this  Agreement) (the  "Severance  Payments"),  if any of such Severance
     Payments are subject to the tax (the "Excise  Tax") imposed by Section 4999
     of the Code (or any similar federal,  state or local tax that may hereafter
     be imposed),  the Company  shall pay to Executive at the time  specified in
     Section 9(b)(iii) hereof an additional amount (the "Gross-Up Payment") such
     that the net amount  retained by Executive,  after  deduction of any Excise
     Tax on the Total Payments (as hereinafter  defined) and any federal,  state
     and local  income  tax and  Excise  Tax upon the  payment  provided  for by
     Section 9(b)(i), shall be equal to the Total Payments.

       (i)    For purposes of determining  whether any of the Severance Payments
              will be subject  to the  Excise Tax and the amount of such  Excise
              Tax:

              (A)    any other  payments or benefits  received or to be received
                     by  Executive  in  connection  with a Change in  Control or
                     Executive's  termination of employment (whether pursuant to
                     the terms of this Agreement or any other plan,  arrangement
                     or  agreement  with the Company,  any Person whose  actions
                     result in a Change in Control or any Person affiliated with
                     the  Company  or such  Person)  (which,  together  with the
                     Severance Payments,  constitute the "Total Payments") shall
                     be treated as  "parachute  payments"  within the meaning of
                     Section  280G(b)(2) of the Code, and all "excess  parachute
                     payments"  within the meaning of Section  280G(b)(1) of the
                     Code shall be treated as subject to the Excise Tax,  unless
                     in  the  opinion  of   nationally-recognized   tax  counsel
                     selected by Executive  such other  payments or benefits (in
                     whole or in part) do not constitute parachute payments,  or
                     such  excess  parachute  payments  (in  whole  or in  part)
                     represent  reasonable  compensation  for services  actually
                     rendered  within the meaning of Section  280G(b)(4)  of the
                     Code in excess of the base  amount  within  the  meaning of
                     Section  280G(b)(3)  of  the  Code,  or are  otherwise  not
                     subject to the Excise Tax;

              (B)    the amount of the Total  Payments which shall be treated as
                     subject  to the  Excise Tax shall be equal to the lesser of
                     (x) the  total  amount of the  Total  Payments  and (y) the
                     amount of excess  parachute  payments within the meaning of
                     Section  280G(b)(1)  of the Code  (after  applying  Section
                     9(b)(i)(A) hereof); and

              (C)    the value of any non-cash benefits or any deferred payments
                     or benefit shall be  determined by a  nationally-recognized
                     accounting  firm selected by Executive in  accordance  with
                     the principles of Sections 280G(d)(3) and (4) of the Code.

       (ii)   For purposes of  determining  the amount of the Gross-Up  Payment,
              Executive  shall be  deemed  to pay  federal  income  taxes at the
              highest marginal rate of


                                      -24-
<PAGE>

              federal income taxation in the calendar year in which the Gross-Up
              Payment  is to be made and  state and  local  income  taxes at the
              highest  marginal  rate of taxation  in the state and  locality of
              Executive's  residence  on the  Date  of  Termination,  net of the
              maximum  reduction in federal income taxes which could be obtained
              from  deduction of such state and local  taxes.  In the event that
              the  Excise  Tax is  subsequently  determined  to be less than the
              amount taken into account  hereunder at the time of termination of
              Executive's  employment,  Executive  shall  repay  to the  Company
              within ten days  after the time that the amount of such  reduction
              in Excise Tax is finally  determined  the portion of the  Gross-Up
              Payment  attributable  to such reduction  (plus the portion of the
              Gross-Up  Payment  attributable  to the Excise Tax and federal and
              state and local income tax imposed on the Gross-Up  Payment  being
              repaid by  Executive if such  repayment  results in a reduction in
              Excise  Tax  and/or   federal  and  state  and  local  income  tax
              deduction)  plus  interest on the amount of such  repayment at the
              rate provided in Section  1274(b)(2)(B)  of the Code. In the event
              that the Excise Tax is  determined to exceed the amount taken into
              account  hereunder at the time of the  termination  of Executive's
              employment  (including  by reason of any payment the  existence or
              amount of which cannot be  determined  at the time of the Gross-Up
              Payment), the Company shall make an additional gross-up payment in
              respect  of such  excess  within  ten days after the time that the
              amount of such excess is finally determined.

       (iii)  The  payments  provided for in this Section 9(b) shall be made not
              later than the fifteenth  day  following  the date of  Executive's
              termination of employment;  provided,  however, that if the amount
              of such  payments  cannot be finally  determined on or before such
              day,  the Company  shall pay to Executive on such day an estimate,
              as determined in good faith by the Company,  of the minimum amount
              of such  payments  and shall pay the  remainder  of such  payments
              (together   with   interest  at  the  rate   provided  in  Section
              1274(b)(2)(B)  of the Code) as soon as the amount  thereof  can be
              determined  but in no event later than the thirtieth day after the
              date of Executive's  termination of employment.  In the event that
              the  amount  of  the   estimated   payments   exceeds  the  amount
              subsequently  determined  to have  been  due,  such  excess  shall
              constitute  a loan by the  Company  to  Executive,  payable on the
              fifteenth  day after  the  demand by the  Company  (together  with
              interest  at the rate  provided  in Section  1274(b)(2)(B)  of the
              Code).

       (iv)   All  determinations  under this  Section 9(b) shall be made at the
              expense  of  the  Company  by  a  nationally   recognized   public
              accounting  firm  selected by  Executive,  and such  determination
              shall be binding upon Executive and the Company.

10.  Non-Competition     and     Non-Disclosure;      Executive     Cooperation;
     Non-Disparagement.

          (a)  Non-Competition.  Without  the  consent  in writing of the Board,
     Executive  



                                      -25-
<PAGE>

     will  not,  at any time  during  the Term  and for a  period  of two  years
     following  termination  of Executive's  employment  for any reason,  acting
     alone or in  conjunction  with others,  directly or  indirectly  (i) engage
     (either  as owner,  investor,  partner,  stockholder,  employer,  employee,
     consultant,  advisor,  or  director)  in any  business in which he has been
     directly  engaged  on  behalf  of  the  Company  or any  affiliate,  or has
     supervised as an executive thereof, during the last two years prior to such
     termination,  or which was  engaged  in or  planned  by the  Company  or an
     affiliate at the time of such termination,  in any geographic area in which
     such  business was  conducted or planned to be  conducted;  (ii) induce any
     customers of the Company or any of its  affiliates  with whom Executive has
     had contacts or  relationships,  directly or indirectly,  during and within
     the scope of her employment with the Company or any of its  affiliates,  to
     curtail or cancel their  business  with the Company or any such  affiliate;
     (iii) induce,  or attempt to influence,  any employee of the Company or any
     of its affiliates to terminate employment;  or (iv) solicit, hire or retain
     as an employee or independent contractor,  or assist any third party in the
     solicitation,  hire, or retention as an employee or independent contractor,
     any person who during the previous 12 months was an employee of the Company
     or any  affiliate;  provided,  however,  that the  limitation  contained in
     clause (i) above shall not apply if Executive's employment is terminated as
     a result of a  termination  by the Company  without  Cause within two years
     following a Change in Control or is terminated by Executive for Good Reason
     within two years following a Change in Control; and provided further,  that
     activities  engaged in by or on behalf of the Company are not restricted by
     this covenant.  The provisions of subparagraphs  (i), (ii), (iii), and (iv)
     above are  separate  and distinct  commitments  independent  of each of the
     other  subparagraphs.  It is agreed that the ownership of not more than one
     percent of the equity securities of any company having securities listed on
     an exchange or regularly traded in the  over-the-counter  market shall not,
     of itself, be deemed inconsistent with clause (i) of this Section 10(a).

          (b)  Non-Disclosure;  Ownership of Work.  Executive  shall not, at any
     time  during  the  Term and  thereafter  (including  following  Executive's
     termination  of employment for any reason),  disclose,  use,  transfer,  or
     sell,  except in the  course of  employment  with or other  service  to the
     Company, any proprietary information,  secrets,  organizational or employee
     information, or other confidential information belonging or relating to the
     Company and its  affiliates and customers so long as such  information  has
     not  otherwise  been  disclosed or is not  otherwise in the public  domain,
     except as required by law or pursuant to legal process.  In addition,  upon
     termination  of  employment  for any reason,  Executive  will return to the
     Company  or  its  affiliates  all  documents  and  other  media  containing
     information  belonging  or  relating  to the  Company  or  its  affiliates.
     Executive will promptly  disclose in writing to the Company all inventions,
     discoveries,  developments,   improvements  and  innovations  (collectively
     referred to as  "Inventions")  that  Executive has conceived or made during
     the Term; provided,  however, that in this context "Inventions" are limited
     to those  which (i) relate in any manner to the  existing  or  contemplated
     business or research activities of the Company and its affiliates; (ii) are
     suggested  by or result  from  Executive's  work at the  Company;  or (iii)
     result from the use of the time, materials or facilities of the Company and
     its affiliates.  All Inventions will be the Company's  property rather than
     Executive's.  Should the Company request it,  Executive  agrees to sign any
     document that the Company may reasonably require to establish  ownership in
     any Invention.

          (c)  Cooperation  With  Regard  to  Litigation.  Executive  agrees  to
     cooperate  with the  Company,  during  the Term and  thereafter  (including
     following Executive's  termination of employment for any reason), by making
     herself  available to testify on behalf of the Company or any subsidiary or
     affiliate of the  Company,  in any action,  suit,  or  proceeding,  whether
     civil,  criminal,  administrative,  or  investigative,  and to  assist  the
     Company, or any subsidiary or affiliate of the Company, in any such action,
     suit, or proceeding,  by providing  information  and meeting and consulting
     with the Board or its  representatives  or counsel,  or  representatives or
     counsel to the Company,  or any subsidiary or affiliate of the Company,  as
     requested.  The Company agrees to reimburse the Executive,  on an after-tax
     basis, for all expenses  actually incurred in connection with her provision
     of testimony or assistance.

          (d)  Non-Disparagement.  Executive  shall not,  at any time during the
     Term and  thereafter,  make  statements  or  representations,  or otherwise
     communicate,  directly or indirectly,  in writing, orally, or otherwise, or
     take any action which may, directly or indirectly, disparage or be damaging
     to the Company or any of its subsidiaries or affiliates or their respective
     officers,  directors,   employees,  advisors,  businesses  or  reputations.
     Notwithstanding  the foregoing,  nothing in this  Agreement  shall preclude
     Executive from making  truthful  statements that are required by applicable
     law, regulation or legal process.

          (e) Release of Employment Claims.  Executive agrees, as a condition to
     receipt of any termination payments and benefits provided for in Sections 6
     and 7 herein (other than  Compensation  Accrued at  Termination),  that she
     will execute a general  release  agreement,  in a form  satisfactory to the
     Company, releasing any and all claims arising out of Executive's employment
     (other than enforcement of this Agreement).

          (f)  Forfeiture of Outstanding  Options.  The provisions of Sections 6
     and 7  notwithstanding,  if Executive  willfully  and  materially  fails to
     substantially comply with any restrictive covenant under this Section 10 or
     willfully and materially  fails to  substantially  comply with any material
     obligation  under this  Agreement,  all  options to purchase  Common  Stock
     granted  by the  Company  and then held by  Executive  or a  transferee  of
     Executive  shall be immediately  forfeited and thereupon such options shall
     be cancelled.  Notwithstanding  the foregoing,  Executive shall not forfeit
     any option unless and until there shall have been delivered to her,  within
     six  months  after the  Board  (i) had  knowledge  of  conduct  or an event
     allegedly  constituting  grounds for such forfeiture and (ii) had reason to
     believe that such conduct or event could be grounds for such forfeiture,  a
     copy of a  resolution  duly adopted by a majority  affirmative  vote of the
     membership  of the Board  (excluding  Executive)  at a meeting of the Board
     called and held for such purpose (after giving Executive  reasonable notice
     specifying the nature of the grounds for such  forfeiture and not less than
     30 days to correct the acts or omissions complained of, if correctable, and
     affording Executive the opportunity, together with her counsel, to be heard
     before the Board)  finding  that,  in the good faith  opinion of the Board,
     Executive  has engaged and continues to engage in conduct set forth in this
     Section  10(f) which  constitutes  grounds for  forfeiture  of  Executive's
     options; provided,  however, that if any option is exercised after delivery
     of such notice and the Board subsequently makes the determination described
     in this  sentence,  Executive  shall be  required  to pay to the Company an
     amount equal to the  difference  between the aggregate  value of the shares
     acquired upon such exercise at the date of the Board  determination and the
     aggregate exercise price paid by Executive. Any such 


                                      -27-
<PAGE>

     forfeiture  shall  apply  to  such  options  notwithstanding  any  term  or
     provision of any option agreement.

          (g)  Survival.  The  provisions  of this Section 10 shall  survive the
     termination  of  the  Term  and  any  termination  or  expiration  of  this
     Agreement.

11.  Governing Law; Disputes; Arbitration.

          (a)  Governing  Law.  This  Agreement  is  governed  by  and  is to be
     construed,  administered,  and enforced in accordance  with the laws of the
     State of Connecticut, without regard to conflicts of law principles, except
     insofar  as  federal  laws  and  regulations   and  the  Delaware   General
     Corporation Law may be applicable.  If under the governing law, any portion
     of  this  Agreement  is at any  time  deemed  to be in  conflict  with  any
     applicable statute, rule, regulation, ordinance, or other principle of law,
     such  portion  shall be deemed to be  modified  or  altered  to the  extent
     necessary  to conform  thereto or, if that is not  possible,  to be omitted
     from this  Agreement.  The  invalidity of any such portion shall not affect
     the force,  effect,  and validity of the remaining  portion hereof.  If any
     court determines that any provision of Section 10 is unenforceable  because
     of the duration or geographic  scope of such provision,  it is the parties'
     intent  that such  court  shall have the power to modify  the  duration  or
     geographic  scope of such  provision,  as the case  may be,  to the  extent
     necessary to render the provision  enforceable  and, in its modified  form,
     such provision shall be enforced.

          (b)  Reimbursement  of Expenses in Enforcing  Rights.  All  reasonable
     costs and expenses  (including fees and  disbursements of counsel) incurred
     by  Executive  in seeking to interpret  this  Agreement  or enforce  rights
     pursuant  to this  Agreement  shall be paid on behalf of or  reimbursed  to
     Executive  promptly by the Company,  whether or not Executive is successful
     in asserting such rights; provided, however, that no reimbursement shall be
     made of such expenses  relating to any unsuccessful  assertion of rights if
     and to the extent  that  Executive's  assertion  of such  rights was in bad
     faith or frivolous, as determined by arbitrators in accordance with Section
     11(c) or a court having jurisdiction over the matter.

          (c)  Arbitration.  Any  dispute  or  controversy  arising  under or in
     connection with this Agreement shall be settled  exclusively by arbitration
     in Westport CT by three  arbitrators  in  accordance  with the rules of the
     American  Arbitration  Association  in effect at the time of  submission to
     arbitration. Judgment may be entered on the arbitrators' award in any court
     having  jurisdiction.  For purposes of entering any judgment  upon an award
     rendered by the  arbitrators,  the Company and Executive  hereby consent to
     the  jurisdiction  of any or all of the  following  courts:  (i) the United
     States  District  Court for the  District of  Connecticut,  (ii) any of the
     courts  of the  State of  Connecticut,  or (iii)  any  other  court  having
     jurisdiction.  The Company and Executive  further agree that any service of
     process or notice requirements in any such proceeding shall be satisfied if
     the rules of such court relating thereto have been substantially satisfied.
     The Company and Executive  hereby waive, to the fullest extent permitted by
     applicable  law, any objection  which it may now or hereafter  have to such
     jurisdiction  and any  defense  of  inconvenient  forum.  The  Company  and
     Executive  hereby  agree  that a  judgment  upon an award  rendered  by the
     arbitrators may be enforced in other  jurisdictions by suit on the judgment
     or in any other  manner  provided  by law.  Subject to Section  11(b),  the
     Company shall 


                                      -28-
<PAGE>

     bear all costs and  expenses  arising in  connection  with any  arbitration
     proceeding  pursuant to this Section 11.  Notwithstanding  any provision in
     this Section 11,  Executive shall be entitled to seek specific  performance
     of  Executive's  right to be paid  during the  pendency  of any  dispute or
     controversy arising under or in connection with this Agreement.

          (d) Interest on Unpaid  Amounts.  Any amount which has become  payable
     pursuant to the terms of this  Agreement or any decision by  arbitrators or
     judgment by a court of law  pursuant  to this  Section 11 but which has not
     been  timely  paid shall bear  interest  at the prime rate in effect at the
     time  such  amount  first  becomes  payable,  as  quoted  by the  Company's
     principal bank.

12.  Miscellaneous.

          (a)  Integration.  This  Agreement  cancels and supersedes any and all
     prior agreements and understandings between the parties hereto with respect
     to the  employment of Executive by the Company,  any parent or  predecessor
     company,  and the  Company's  subsidiaries  during  the  Term,  except  for
     contracts  relating  to  compensation  under  executive   compensation  and
     employee benefit plans of the Company and its  subsidiaries.  The foregoing
     notwithstanding,  Executive shall not participate in the Company's Employee
     Protection Plan. This Agreement  constitutes the entire agreement among the
     parties with respect to the matters herein provided, and no modification or
     waiver of any  provision  hereof shall be  effective  unless in writing and
     signed  by the  parties  hereto.  Executive  shall not be  entitled  to any
     payment  or benefit  under this  Agreement  which  duplicates  a payment or
     benefit received or receivable by Executive under such prior agreements and
     understandings or under any benefit or compensation plan of the Company.

          (b)  Successors;   Transferability.  The  Company  shall  require  any
     successor (whether direct or indirect, by purchase,  merger,  consolidation
     or otherwise) to all or substantially  all of the business and/or assets of
     the Company to expressly  assume and agree to perform this Agreement in the
     same manner and to the same  extent  that the Company  would be required to
     perform  it if no  such  succession  had  taken  place.  As  used  in  this
     Agreement, "Company" shall mean the Company as hereinbefore defined and any
     successor to its business  and/or  assets as  aforesaid  which  assumes and
     agrees to perform this  Agreement by operation of law, or otherwise and, in
     the case of an acquisition of the Company in which the corporate  existence
     of the Company  continues,  the  ultimate  parent  company  following  such
     acquisition.  Subject to the foregoing, the Company may transfer and assign
     this Agreement and the Company's rights and obligations hereunder.  Neither
     this  Agreement  nor the rights or  obligations  hereunder  of the  parties
     hereto  shall  be  transferable  or  assignable  by  Executive,  except  in
     accordance  with the laws of descent and  distribution  or as  specified in
     Section 12(c).

          (c)  Beneficiaries.  Executive  shall be  entitled to  designate  (and
     change,  to the extent  permitted  under  applicable  law) a beneficiary or
     beneficiaries  to receive any compensation or benefits  provided  hereunder
     following Executive's death.

          (d) Notices.  Whenever  under this  Agreement it becomes  necessary to
     give  notice,  such  notice  shall be in  writing,  signed  by the party or
     parties  giving or making  the same,  



                                      -29-

     and shall be served on the person or persons for whom it is intended or who
     should  be  advised  or  notified,  by  Federal  Express  or other  similar
     overnight  service or by  certified  or  registered  mail,  return  receipt
     requested,  postage  prepaid and addressed to such party at the address set
     forth below or at such other  address as may be designated by such party by
     like notice:

         If to the Company:

         IMS HEALTH INCORPORATED
         200 Nyala Farms
         Westport, CT  06880
         Attention:  General Counsel

         If to Executive:

         Victoria R. Fash
         200 Nyala Farms
         Westport, CT  06880

     If the  parties by mutual  agreement  supply  each  other  with  telecopier
     numbers for the  purposes of  providing  notice by  facsimile,  such notice
     shall also be proper  notice under this  Agreement.  In the case of Federal
     Express or other similar overnight service,  such notice or advice shall be
     effective  when sent,  and, in the cases of certified or  registered  mail,
     shall be effective two days after deposit into the mails by delivery to the
     U.S. Post Office.

          (e) Reformation. The invalidity of any portion of this Agreement shall
     not deemed to render the remainder of this Agreement invalid.

          (f) Headings.  The headings of this  Agreement are for  convenience of
     reference only and do not constitute a part hereof.

          (g) No  General  Waivers.  The  failure  of any  party  at any time to
     require performance by any other party of any provision hereof or to resort
     to any remedy provided herein or at law or in equity shall in no way affect
     the right of such party to require  such  performance  or to resort to such
     remedy  at any time  thereafter,  nor  shall  the  waiver by any party of a
     breach  of any of the  provisions  hereof  be  deemed to be a waiver of any
     subsequent  breach of such  provisions.  No such waiver  shall be effective
     unless in  writing  and  signed by the party  against  whom such  waiver is
     sought to be enforced.

          (h) No Obligation To Mitigate. Executive shall not be required to seek
     other  employment  or  otherwise to mitigate  Executive's  damages upon any
     termination of employment; provided, however, that, to the extent Executive
     receives from a subsequent employer health or other insurance benefits that
     are  substantially  similar to the  benefits  referred  to in Section  5(b)
     hereof,  any such  benefits  to be  provided  by the  Company to  Executive
     following the Term shall be correspondingly reduced.

          (i)  Offsets;  Withholding.  The  amounts  required  to be paid by the
     Company to  Executive  pursuant to this  Agreement  shall not be subject to
     offset  other than with respect to any amounts that are owed to the Company
     by  Executive  due to her  receipt  of funds as a result of her  fraudulent
     activity.   The   foregoing  and  other   provisions   of  this   Agreement
     notwithstanding, all payments to be made to Executive under this Agreement,
     including  under  Sections 6 and 7, or otherwise  by the  Company,  will be


                                      -30-
<PAGE>

     subject to  withholding  to satisfy  required  withholding  taxes and other
     required deductions.

          (j) Successors and Assigns.  This Agreement  shall be binding upon and
     shall  inure  to  the   benefit  of   Executive,   her  heirs,   executors,
     administrators  and  beneficiaries,  and shall be binding upon and inure to
     the benefit of the Company and its successors and assigns.

          (k) Counterparts. This Agreement may be executed in counterparts, each
     of which shall be deemed to be an original but all of which  together  will
     constitute one and the same instrument.

13.  Indemnification.

     All rights to  indemnification  by the Company now existing in favor of the
Executive as provided in the Company's  Certificate of  Incorporation or By-laws
or  pursuant  to other  agreements  in  effect  on or  immediately  prior to the
Effective  Date shall  continue in full force and effect from the Effective Date
(including all periods after the expiration of the Term),  and the Company shall
also advance  expenses for which  indemnification  may be ultimately  claimed as
such expenses are incurred to the fullest extent permitted under applicable law,
subject to any  requirement  that the Executive  provide an undertaking to repay
such advances if it is ultimately  determined that the Executive is not entitled
to indemnification;  provided,  however,  that any determination  required to be
made with respect to whether the Executive's conduct complies with the standards
required to be met as a condition of  indemnification or advancement of expenses
under applicable law and the Company's Certificate of Incorporation, By-laws, or
other agreement shall be made by independent  counsel mutually acceptable to the
Executive  and the  Company  (except to the extent  otherwise  required by law).
After  the  date  hereof,  the  Company  shall  not  amend  its  Certificate  of
Incorporation or By-laws or any agreement in any manner which adversely  affects
the  rights  of the  Executive  to  indemnification  thereunder.  Any  provision
contained herein  notwithstanding,  this Agreement shall not limit or reduce any
rights of the  Executive  to  indemnification  pursuant  to  applicable  law. In
addition, the Company will maintain directors' and officers' liability insurance
in effect and covering acts and omissions of Executive during the Term and for a
period of six years  thereafter on terms  substantially  no less  favorable than
those in effect on the Effective Date.

     IN WITNESS WHEREOF, Executive has hereunto set her hand and the Company has
caused this  instrument  to be duly  executed as of the day and year first above
written.

Dear Ms. Henry and Mr. Doppelt:

       Reference is made to the Distribution  Agreement (the "1996  Distribution
Agreement"),   dated  as  of  October  28,  1996,  among  Cognizant  Corporation
("Cognizant"),   The  Dun  &  Bradstreet   Corporation   ("D&B")  and  ACNielsen
Corporation  ("ACNielsen").  Cognizant  has  announced its intention to separate
into  two  separate   companies   through  a   distribution   (the  "IMS  HEALTH
Distribution")  to its  stockholders of all of the shares of common stock of its
subsidiary IMS Health Incorporated ("IMS HEALTH"). In Section 8.9(c) of the 1996
Distribution Agreement,  Cognizant agreed not to make a distribution such as the
IMS HEALTH  Distribution unless it caused the distributed entity to undertake to
both D&B and  ACNielsen  to be jointly and  severally  liable for all  Cognizant
Liabilities  (as  defined in 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 IMS HEALTH
Distribution,  IMS HEALTH  undertakes to each of D&B and ACNielsen to be jointly
and severally liable with Cognizant for all Cognizant Liabilities under the 1996
Distribution Agreement.

                                                   Very truly yours,

                                                   IMS HEALTH INCORPORATED

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
Gartner Group, Inc.:

We have audited the accompanying consolidated balance sheets of Gartner Group,
Inc. and subsidiaries as of September 30, 1998 and 1997, and the related
consolidated statements of operations, changes in stockholders' equity and cash
flows for each of the years in the three-year period ended September 30, 1998.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Gartner Group, Inc.
and subsidiaries as of September 30, 1998 and 1997, and the results of their
operations and their cash flows for each of the years in the three-year period
ended September 30, 1998, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION. The consolidated financial statements include the
accounts of Gartner Group, Inc. ("GGI" or the "Company") and its majority-owned
subsidiaries. All significant intercompany transactions and balances have been
eliminated. Minority interest represents the minority stockholder's
proportionate share of the equity in businesses owned less than 100%. The
results of operations for acquisitions of companies accounted for using the
purchase method have been included in the Consolidated Statements of Operations
beginning on the effective date of acquisition. The Company's investments in 20%
to 50% owned companies in which it has the ability to exercise significant
influence over operating and financial policies are accounted for on the equity
method. Investments of less than 20% are carried at cost.

REVENUE AND COMMISSION EXPENSE RECOGNITION. Revenue from advisory, measurement
and learning ("AML") contracts is recognized as products and services are
delivered, and as the Company's obligation to the client is completed over the
contract, generally twelve months. The Company's policy is to record at the time
of signing of an AML contract the fees receivable and related deferred revenues
for the full amount of the contract billable on that date. All such contracts
are non-cancelable and non-refundable, except for government contracts which
have a 30-day cancellation clause. Government contracts have not produced
material cancellations to date. All contracts are billable upon signing, absent
special terms granted on a limited basis. The Company also records the related
commission obligation upon the signing of the contract and amortizes the
corresponding deferred commission expense over the contract period in which the
related revenues are earned and amortized to income. Revenue from software
licensing fees is recognized when the products have been delivered,
collectibility is probable, and the related software license fees are fixed or
determinable. Components of revenues attributable to future service are deferred
and recognized as such services are performed. Other revenues consist
principally of revenues recognized as earned from consulting services and
conferences.

CASH EQUIVALENTS AND MARKETABLE SECURITIES. Marketable securities that mature
within three months of purchase are considered cash equivalents. Investments
with maturities of more than three months are classified as marketable
securities. The Company's marketable securities consist of marketable debt
securities which are classified as held-to-maturity and valued at amortized
cost, which approximates market. It is management's intent to hold all
investments to maturity.

INVENTORIES. Inventories, which have primarily consisted of finished goods
related to the Company's training business, GartnerLearning, are stated at the
lower of cost or market. Cost is determined on a first-in, first-out basis.
Inventories consist primarily of material costs, and are included in the balance
sheet caption "Prepaid expenses and other current assets". Inventories were $0
and $2.1 million at September 30, 1998 and 1997, respectively.

PROPERTY, EQUIPMENT AND LEASEHOLD IMPROVEMENTS. Property, equipment and
leasehold improvements are stated at cost less accumulated depreciation and
amortization. Property and equipment are depreciated using the straight-line
method over the estimated useful lives of the assets. Leasehold improvements are
amortized using the straight-line method over the shorter of the estimated
useful lives of the asset or the remaining term of the related leases.

SOFTWARE DEVELOPMENT COSTS. Under Statement of Financial Accounting Standards
No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or
Otherwise Marketed," capitalization of computer software development costs is to
begin upon the establishment of technological feasibility, limited to the net
realizable value of the software product, and cease when the software product is
available for general release to clients. Until these products reach
technological feasibility, all costs related to development efforts are charged
to expense. Amortization of capitalized computer software development costs
begins when the products are available for general release to customers.
Software development costs, subsequent to technological feasibility and prior to
general release, have not been material and have been expensed.

INTANGIBLE ASSETS. Intangible assets include goodwill, non-compete agreements,
tradenames and other intangibles. Goodwill represents the excess of the purchase
price of acquired businesses over the estimated fair value of the tangible and
identifiable intangible net assets acquired. Amortization is recorded using the
straight-line method over periods ranging from seven to thirty years. These
amounts have been and are subject to adjustment in accordance with the
provisions of the Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes" ("FAS 109") (see Note 9. Income Taxes).
Non-compete agreements are being amortized on a straight-line basis over the
period of the agreement ranging from three to five years. Tradenames and other
intangibles are being amortized on a straight-line basis over their estimated
useful lives ranging from four to thirty years. At the end of each quarter, the
Company reviews events and

changes in circumstances to determine whether the recoverability of the carrying
value of the intangible asset should be assessed. Should events or circumstances
indicate that the carrying value may not be recoverable based on undiscounted
future cash flows, an impairment loss measured by the difference between the
discounted future cash flows (or another acceptable method for determining fair
value) and the carrying value of the intangible would be recognized by the
Company.

FOREIGN CURRENCY TRANSLATION. All assets and liabilities of foreign subsidiaries
are translated into U.S. dollars at fiscal year-end exchange rates. Income and
expense items are translated at average exchange rates prevailing during the
fiscal year. The resulting translation adjustments are recorded as a component
of stockholders' equity.

INCOME TAXES. Deferred tax assets and liabilities are recognized based on
differences between the book and tax bases of assets and liabilities using
presently enacted tax rates. The provision for income taxes is the sum of the
amount of income tax paid or payable for the year as determined by applying the
provisions of enacted tax laws to taxable income for that year and the net
changes during the year in the Company's deferred tax assets and liabilities.

     Undistributed earnings of subsidiaries outside of the U.S. amounted to
approximately $12.1 million and will either be indefinitely reinvested or
remitted substantially free of tax. Accordingly, no material provision has been
made for taxes that may be payable upon remittance of such earnings, nor is it
practicable to determine the amount of this liability. The Company credits
additional paid-in capital for realized tax benefits arising from stock
transactions with employees. The tax benefit on a non-qualified stock option is
equal to the tax effect of the difference between the market price of a share of
the Company's common stock on the exercise and grant dates. To the extent the
Company incurs employment taxes as a direct result of the exercise of such stock
options, this cost is charged to additional paid-in capital.

COMPUTATIONS OF INCOME PER SHARE OF COMMON STOCK. In February 1997, Statement of
Financial Accounting Standards No. 128 "Earning per Share" ("FAS 128") was
issued. The Statement sets forth guidance on the presentation of earnings per
share ("EPS") and requires dual presentation of basic and diluted earnings per
share on the face of the income statement. Basic EPS is computed by dividing
earnings available to common stockholders by the weighted average number of
common shares outstanding for the period. Diluted EPS reflects the potential
dilution of securities that could share in earnings, including stock options and
warrants. EPS amounts have been calculated and presented under the provisions of
FAS 128.

     The following table sets forth the required disclosures of the
reconciliation of the basic and diluted net earnings per share computations.

$32.67 were not included in the calculation because the effect would have been
antidilutive. All outstanding options for the fiscal years ended September 30,
1997 and 1996 were dilutive and were included in the calculation of diluted
earnings per share.

RECENTLY ISSUED ACCOUNTING STANDARDS. In June 1997, Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("FAS 130") and
"Disclosures about Segments of an Enterprise and Related Information" ("FAS
131") were issued. FAS 130 establishes standards for reporting and disclosure of
comprehensive income and its components in a full set of general-purpose
financial statements. This statement requires that all items that are required
to be recognized under accounting standards as components of comprehensive
income be reported in a financial statement that is displayed with the same
prominence as other financial statements. FAS 131 establishes standards for the
way that public business enterprises report information about operating segments
in annual financial statements and requires that those enterprises report
selected information about operating segments in interim financial reports
issued to stockholders which is currently not required. It also establishes
standards for related disclosures about products and services, geographic areas
and major customers. The Company is required to adopt both new disclosure
standards in the first quarter of fiscal 1999.

     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1 ("SOP 98-1"), "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use". SOP 98-1 requires
companies to capitalize certain costs of computer software developed or obtained
for internal use and amortize such costs over the software's estimated useful
life. The Company is required to adopt SOP 98-1 in fiscal 2000. The Company is
currently evaluating the effect of adoption of SOP 98-1 on the Company's
financial position and results of operations.

     In June 1998, Statement of Financial Accounting Standard No. 133,
"Accounting for Derivative Instruments and Hedging Activities " ("FAS 133") was
issued. FAS 133 establishes a new model for accounting for derivatives and
hedging activities. The Statement requires all derivatives be recognized in the
statement of financial position as either assets or liabilities and measured at
fair value. The Company is required to adopt FAS 133 in fiscal 2000. The Company
is currently evaluating the effect of adoption of FAS 133 on the Company's
financial position and results of operations.

FAIR VALUE OF FINANCIAL INSTRUMENTS. Most of Company's financial instruments,
including cash, marketable securities, trade receivables and payables, and
accruals are short-term in nature. Accordingly, the carrying amount of these
financial instruments approximates its fair value (see Note 11 regarding forward
purchase agreements).

CONCENTRATIONS OF CREDIT RISK. Financial instruments that potentially subject
the Company to concentrations of credit risk consist primarily of cash,
marketable securities and fees receivable. The Company invests its cash
primarily in a diversified portfolio of highly-rated municipal and government
bonds. Concentrations of credit risk with respect to fees receivables are
limited due to the large number of customers comprising the Company's customer
base and their dispersion across many different industries and geographic
regions.

USE OF ESTIMATES. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities and
disclosures, if any, of contingent assets and liabilities at the dates of the
financial statements and the reported amounts of revenues and expenses during
the reporting periods. Actual results could differ from those estimates.
Estimates are used when accounting for such items as allowance for doubtful
accounts, depreciation, amortization, income taxes and certain accrued
liabilities.


2--RELATED PARTIES

The Dun and Bradstreet Corporation ("D&B"), an investor in Information Partners
Capital Fund, L.P. ("the Fund"), provided a portion of the financing in
connection with the acquisition of the Company in October 1990. In April 1993,
D&B acquired a majority of the outstanding voting securities of the Company in
transactions among the Company, D&B and persons and entities associated with the
Fund. On November 1, 1996, D&B transferred ownership of its Class A and Class B
Common Stock of the Company to Cognizant Corporation ("Cognizant"), a spin-off
of D&B and an independent public company. At the date of transfer, these shares
represented 51% of the Company's outstanding common stock. During fiscal 1997,
Cognizant's ownership of the Company's outstanding common stock fell below 50%.
On June 30, 1998, Cognizant transferred its ownership in the Company to IMS
Health Incorporated, ("IMS Health"), a spin-off of Cognizant and an independent
public company. (See Note 18--Subsequent Event.)

     On June 4, 1997, with the Board of Directors approval, the Company provided
loans totaling $7.2 million to certain officers to facilitate the purchase of
common stock arising out of the exercise of stock options. The loans proceeds
were not used to fund the option exercise price of the common stock acquired.
The loans were full recourse obligations to the officers and were secured by
shares of the Company's stock. The loans bore interest at an annual rate of
6.1%. The principal amount of the loans totaling $7.2 million are included in
other assets on the September 30, 1997 Consolidated Balance Sheets. On December
18, 1997, with the Board of Directors approval, the Company provided additional
loans for the same purpose to certain officers totaling $2.5 million. The loans
bore interest at an annual rate of 5.6%. On July 23, 1998, with Board of
Directors' approval, the Company received 302,003 shares of Class A Common Stock
in settlement of the loan balance and accrued interest due.


3--ACQUISITIONS

On December 1, 1995, the Company acquired all the outstanding shares of
Dataquest, a wholly-owned subsidiary of D&B, for consideration of $15.0 million
in cash, 3,000,000 shares of Class A Common Stock with an approximate fair
market value of $60.0 million, and a five year warrant to purchase 600,000
shares of Class A Common Stock at $16.42 per share. Dataquest is a provider of
information technology ("IT") market research and consulting for the IT vendor
manufacturer and financial communities which complements the GGI end user focus.
The Company has accounted for the acquisition as a transfer and exchange between
companies under common control and the 3,000,000 shares have been assumed to be
outstanding for all periods presented. Accordingly, the accounts of Dataquest
have been combined with the Company's at historical cost in a manner similar to
a pooling of interests. Transaction costs of $1.7 million relating to the
acquisition have been included in acquisition-related charges in the
Consolidated Statement of Operations for fiscal 1996.

     Combined and separate results of the Company and Dataquest during the
periods preceding the merger were as follows (in thousands):

There were no intercompany transactions between the two companies for the
period.

     On July 31, 1996, the Company acquired all of the outstanding shares of J3
Learning Corporation ("J3") for consideration of approximately $8.0 million in
cash, 1,065,290 shares of Class A Common Stock which had an approximate fair
market value of $35.4 million and options to purchase Class A Common Stock which
had a value of $1.3 million. J3 publishes, markets and distributes software
educational materials for corporate and individual training (collectively known
as "technology based training"). The acquisition was accounted for by the
purchase method, and the purchase price has been allocated to the assets
acquired and liabilities assumed, based upon the estimated fair values at the
date of acquisition. The excess purchase price over the fair value of amounts
assigned to the net tangible assets acquired was $51.1 million. Of such amount,
$32.2 million was expensed at acquisition as purchased in-process research and
development costs and is included in acquisition-related charges in the
Consolidated Statement of Operations for fiscal 1996, and substantially all of
the remaining excess purchase price was allocated to goodwill and tradename.

     The following unaudited pro forma summary presents the consolidated results
of operations of the Company for the fiscal year ended September 30, 1996 as if
the acquisition of J3 had occurred at the beginning of the year and does not

     On September 1, 1998, the Company sold its technology based training
business (see Note 4--Sale of GartnerLearning).

     On August 1, 1997, the Company acquired all of the outstanding shares of
Datapro Information Services ("Datapro"), a unit of McGraw-Hill Companies for
consideration of approximately $25.0 million in cash. Datapro is a provider of
information on product specifications and pricing, product comparisons,
technology reports, market overviews, case studies and user ratings surveys.
Datapro's services and products provide feature and side-by-side comparisons of
computer hardware, software and communications products. The acquisition was
accounted for by the purchase method, and the purchase price has been allocated
to the assets acquired and the liabilities assumed, based upon the estimated
fair values at the date of acquisition. The excess purchase price over the fair
value of amounts assigned to the net tangible assets acquired was $33.5 million
and has been recorded as goodwill which is being amortized over 30 years. In
addition, $2.5 million of the purchase price was allocated to a non-compete
agreement which is being amortized over 4 years. If the acquisition of Datapro
had occurred at the beginning of fiscal year 1996, consolidated total revenues
on a pro forma basis would have been $536.6 million and $431.4 million for
fiscal years 1997 and 1996, respectively. This revenue does not purport to be
indicative of what would have occurred had the acquisition been made as of that
date or of total revenues which may occur in the future. The pro forma effect on
the Company's net income and net income per common share for fiscal 1997 and
1996 is not material.

     On October 22, 1997, the Company acquired a 32% membership interest in
Jupiter Communications, LLC ("Jupiter") for $8.0 million in cash. On September
16, 1998, the Company increased its membership interest in Jupiter to 37% for an
additional $1.3 million in cash. Jupiter is a provider of analyst-based research
and strategic planning services to the consumer and Internet and interactive
industries. This investment is accounted for under the equity method of
accounting. The excess of the cost of the investment over the underlying
proportionate share of net assets (goodwill) in Jupiter totaling $9.3 million is
being amortized over 30 years and is included in other assets in the
Consolidated Balance Sheets.

     On January 30, 1998, the Company acquired all the assets and assumed the
liabilities of Interpose, Inc. ("Interpose"), for $7.5 million in cash and
13,746 shares of Class A Common Stock of the Company which had an approximate
fair market value of $0.5 million. Interpose is a provider of total cost of
ownership (TCO) measurement and analysis tools and training. The acquisition was
accounted for by the purchase method, and the purchase price has been allocated
to the assets acquired and liabilities assumed, based upon estimated fair values
at the date of acquisition. The excess purchase price over the fair value of
amounts assigned to the net tangible assets acquired was $7.5 million. Of such
amount, $6.3 million was expensed during the second quarter of 1998 as purchased
in-process research and development costs and is presented as the
acquisition-related charge in the Consolidated Statements of Operations. On
December 10, 1998, the Company revised the amount of expensed purchased
in-process research and development costs from $6.3 million to $4.5 million. The
change was in response to recently developed guidance from the Securities and
Exchange Commission. Of the remaining excess purchase price, $2.3 million was
allocated to goodwill which is being amortized over 12 years and $0.9 million
was allocated to a non-compete agreement which is being amortized over 5 years.

     On May 18, 1998, the Company acquired all the assets and assumed the
liabilities of The Research Board, Inc., for $6.4 million in cash and 183,945
shares of Class A Common Stock of the Company which had an approximate fair
market value of $5.7 million. The Research Board compiles and provides
information technology ("IT") research on suppliers and new technologies,
validated management practices and IT best practices to its membership, which
consist principally of senior IT executives. The acquisition was accounted for
by the purchase method, and the purchase price has been allocated to the assets
acquired and the liabilities assumed, based upon estimated fair values at the
date of acquisition. The excess purchase price over the fair value of amounts
assigned to the net tangible assets acquired was $13.5 million, of which $12.9
million has been recorded as goodwill, which is being amortized over 30 years.
In addition, $0.6 million of the purchase price was allocated to a non-compete
agreement which is being amortized over 5 years.

     On September 4, 1998, the Company acquired all of the outstanding shares of
Vision Events International, Inc., for $20.5 million in cash. Vision Events
International, Inc. produces premiere channel events that serve to bring
information technology vendors, value-added resellers, and system integrators
together with vendors and distributors selling through these channels. The
acquisition was accounted for by the purchase method, and the purchase price has
been allocated to the assets acquired and the liabilities assumed, based upon
estimated fair values at the date of acquisition. The excess purchase price over
the fair value of amounts assigned to the net tangible assets acquired was $24.0
million of which $23.6 million has been recorded as goodwill which is being
amortized over 30 years. In addition, $0.4 million of the purchase price was
allocated to a non-compete agreement which is being amortized over 3 years.

     During fiscal 1998, the Company completed additional acquisitions for
consideration of $12.8 million in cash and 28,236 shares of Class A Common Stock
of the Company which had an approximate fair market value of $0.7 million.

During fiscal 1997, the Company completed additional acquisitions for $8.1
million in cash. These acquisitions have been accounted for under the purchase
method and substantially all of the purchase price has been assigned to
goodwill.

     The pro forma results of operations for fiscal years 1998 and 1997,
assuming the fiscal 1998 acquisitions were made at the beginning of each year
would not differ significantly from the historical results.

     On October 7, 1998, the Company acquired all the assets and assumed the
liabilities of Griggs-Anderson, Inc., for $10.9 million in cash and 306,475
shares of Class A Common Stock of the Company which had an approximate fair
market value of $7.3 million. Griggs-Anderson, Inc. provides custom market
research to vendors in the technology marketplace, research and surveys for the
evaluation of Web sites for effectiveness of content, technical performance,
ease of navigation, impact of graphics, and demographic profiles of users. The
acquisition was accounted for by the purchase method.


4--SALE OF GARTNERLEARNING

On September 1, 1998, the Company sold GartnerLearning, a division of the
Company that provides technology based training and services for information
technology professionals to Netg Inc. ("Netg"), a subsidiary of Harcourt Brace &
Company, for $5.0 million in cash and an 8% equity interest in Netg. In
addition, the Company received a put option which allows the Company to sell its
8% equity interest to an affiliate of Harcourt Brace & Company for $48.0 million
in cash. This put option may be exercised for two years beginning on September
1, 2002, if certain conditions are met. The Company's 8% interest in Netg has an
independently appraised fair value of $42.5 million and is included in other
assets in the Consolidated Balance Sheets. Including transaction costs related
to the sale of $3.8 million, the pre-tax loss on sale of GartnerLearning was
approximately $2.0 million (also see Note 10--Income Taxes for the impact of the
sale on the income tax provision).


5--NONRECURRING CHARGES

During fiscal 1998, the Company recorded nonrecurring charges, primarily
consisting of relocation and severance costs, totaling approximately $2.8
million related to the Company's relocation of certain accounting and order
processing operations from Stamford, Connecticut to a new financial services
center in Ft. Myers, Florida. These expenses are recorded as nonrecurring
charges in the Consolidated Statements of Operations.

     Rental expense for operating leases, net of sublease income, was $21.3
$16.8, and $11.0 million for the fiscal years ended September 30, 1998, 1997 and
1996, respectively. The Company has commitments with two facilities management
companies for printing, copying, mail room and other related services. The
minimum annual obligations under these service agreements are $4.8 million for
fiscal 1998, 1999, and 2000, $4.2 million for fiscal 2001 and 2002, and $1.1
million for fiscal year 2003.

     The Company is involved in legal proceedings and litigation arising in the
ordinary course of business. The Company believes the outcome of all current
proceedings, claims and litigation will not have a material effect on the
Company's financial position or results of operations when resolved in a future
period.


9--LONG-TERM OBLIGATIONS

The Company has available two unsecured credit lines with The Bank of New York
and Chase Manhattan Bank for $5.0 million and $25.0 million, respectively.
Borrowings under The Bank of New York line accrue interest charges at LIBOR plus
2%. Alternatively, the rate shall be the higher of the prime commercial lending
rate of the bank or the Federal Funds Rate plus 1/2 of 1% in the event LIBOR is
unavailable. The Chase Manhattan Bank line carries an interest rate equal to
either the prime rate of Chase Manhattan Bank, LIBOR plus .25% for periods of
30, 60 or 90 days as the Company may choose, or a "fixed option" rate. There are
no commitment fees associated with these lines. These lines may be canceled by
the banks at any time without prior notice or penalty. No borrowings were
outstanding under either line at September 30, 1998 and 1997.

     Letters of credit are issued by the Company in the ordinary course of
business. The Company had outstanding letters of credit with Chase Manhattan
Bank of $4.1 million and $2.0 million with The Bank of New York as of September
30, 1998.

     Current and long-term net deferred tax assets are $1.8 million and $6.2

September 30, 1997, respectively, and are included in Prepaid expenses and other
current assets and other assets, respectively, in the Consolidated Balance
Sheets.

     The valuation allowance relates to domestic and foreign tax loss
carryforwards that more likely than not will expire unutilized. The net increase
in the valuation allowance of approximately $1.5 million in the current year
results primarily from the increase in state tax carryforwards of approximately
$2.0 million and the net utilization of foreign tax loss carryforwards of
approximately $0.5 million. The net decrease in the valuation allowance of
approximately $1.6 million in fiscal 1997 was due primarily from the utilization
of foreign tax loss carryforwards. The tax benefit from such tax loss
carryforwards was $1.2, $1.7, and $1.0 million for fiscal years 1998, 1997, and
1996, respectively. Approximately $3.4 million of the valuation allowance would
reduce paid-in-capital upon subsequent recognition of any related tax benefits.

     The sale of GartnerLearning resulted in an additional tax provision of $4.2
million primarily due to the reversal of non-deductible goodwill. The effective
tax rate, less the impact of the sale of GartnerLearning, was 39%.

     As of September 30, 1998, the Company had U.S. federal tax loss
carryforwards of $10.0 million which will expire in ten to twelve years and
state and local tax loss carryforwards of $57.6 million, the majority of which
will expire in three to five years. The U.S. federal tax loss carryforwards are
subject to limitations on their use under the Internal Revenue Code. In
addition, the Company has foreign tax loss carryforwards of $4.6 million, of
which $0.5 million will expire within three to five years, and $4.1 million can
be carried forward indefinitely.

11--CAPITAL STOCK AND STOCK REPURCHASE PROGRAM

The Company effected a two-for-one stock split of its Class A and Class B Common
Stock by means of a stock dividend in March 1996, June 1995 and August 1994. All
earnings per share and share data presented herein have been restated
retroactively to reflect such splits. As of September 30, 1997, the Company had
recorded the conversion of all Class B Common Stock into Class A Common Stock on
a one for one basis, pursuant to a provision of the Articles of Incorporation
which requires conversion when the Class B Common Stockholder's voting equity
falls below a certain ownership percentage after considering all exercisable
options and warrants outstanding. Class A Common Stock stockholders are entitled
to one vote per share on all matters to be voted by stockholders, other than the
election of directors. Prior to the conversion of the Class B Common Stock,
Class B Common stockholders had certain preferential voting rights with respect
to the election of members of the Board of Directors.

     Beginning in fiscal 1997, the Company has entered into a series of forward
purchase agreements on its Class A Common Stock. These agreements are settled
quarterly at the Company's option on a net basis in either shares of its own
Class A Common Stock or cash. To the extent that the market price of the
Company's Class A Common Stock on a settlement date is higher (lower) than the
forward purchase price, the net differential is received (paid) by the Company.
During fiscal 1997, two settlements resulted in the Company receiving 449,932
shares of Class A Common Stock (recorded in Treasury stock at no cost) and
paying approximately $12.0 million in cash (recorded as a reduction of
additional paid-in capital). During fiscal 1998, four settlements resulted in
the Company receiving 365,949 shares of Class A Common Stock and paying
approximately $12.0 million in cash. As of September 30, 1998, a forward
purchase agreement in place covered approximately $27.2 million or 984,119
shares of Class A Common Stock having forward purchase prices established at
$27.63 per share. If the market priced portion of this agreement was settled
based on the September 30, 1998 market price of Class A Common Stock ($21.94 per
share), the Company would settle under the terms of the forward purchase
agreement with a payment of either $5.6 million in cash or 255,142 shares of
Class A Common Stock.

     On August 24, 1998, the Company's Board of Directors approved the
repurchase of up to 2,500,000 shares of Class A Common Stock. The stock
repurchase program is intended to offset the dilutive effect of the Company's
stock-based employee compensation plans. As of September 30, 1998, the Company

12--EMPLOYEE STOCK PURCHASE PLANS

In January 1993, the Company adopted an employee stock purchase plan (the "1993
Employee Stock Purchase Plan"), and reserved an aggregate of 4,000,000 shares of
Class A Common Stock for issuance under this plan. The plan permits eligible
employees to purchase Class A Common Stock through payroll deductions, which may
not exceed 10% of an employee's compensation (or $21,250 in any calendar year),
at a price equal to 85% of Class A Common Stock price as reported by NYSE at the
beginning or end of each offering period, whichever is lower. During fiscal year
1998, 195,904 shares were issued from treasury stock at an average purchase
price of $30.98 per share in conjunction with this plan. At September 30, 1998,
2,078,933 shares were available for offering under the plan.


13--STOCK OPTIONS AND WARRANTS

Under the terms of the 1991 Stock Option Plan, (the "Option Plan"), the Board of
Directors may grant non-qualified and incentive options, entitling employees to
purchase shares of the Company's common stock at the fair market value on the
date of grant. The Board can determine the date on which options vest and become
exercisable. A total of 32,800,000 and 22,800,000 shares of Class A Common Stock
were reserved for issuance under the Option Plan as of September 30, 1998 and
1997, respectively. In April 1998, the Board of Directors adopted an amendment,
subject to final shareholder approval, to the Option Plan to increase the number
of shares reserved for issuance thereunder by 10,000,000 shares. At September
30, 1998 and 1997, 9,001,508 and 2,955,416 options were available for grant,
respectively.

     In January 1993, the Company adopted a stock option plan for directors (the
"1993 Director Option Plan") and reserved an aggregate of 1,200,000 shares of
Class A Common Stock for issuance under this plan. The plan provided for the
automatic grant of 120,000 options to purchase shares of Class A Common Stock to
each non-employee director upon first becoming a director on or after February
1, 1993, and the automatic grant of an option to purchase an additional 24,000
options to purchase shares of Class A Common Stock annually based on continuous
service as a director. In January 1996, the plan was amended to provide for the
automatic grant of 15,000 options to purchase shares of Class A Common Stock to
each non-employee director upon first becoming a director and the automatic
grant of an option to purchase an additional 3,000 options to purchase shares of
Class A Common Stock annually based on continuous service as a director. The
exercise price of each option granted under the plan is equal to the fair value
of the Class A Common Stock at the date of grant. Options granted are subject to
cumulative yearly vesting over a three year period after the date of grant and
the number of shares to be granted under the amended terms will not be adjusted
for any future stock splits. At September 30, 1998 and 1997, 603,000 and 621,000
options were available for grant, respectively.

     In October 1994, the Board of Directors and stockholders of the Company
approved the adoption of a Long-Term Stock Option Plan ("the 1994 Long-Term
Plan") and the reservation of an aggregate of 6,560,000 shares of Class A Common
Stock for issuance thereunder. The purpose of the plan is to provide to senior
personnel long-term equity participation in the Company as an incentive to
promote the long-term success of the Company. The exercise price of each option
granted under the plan is equal to the fair value of the Class A Common Stock at
the date of grant. All options granted under the plan vest and become fully
exercisable five years following the date of grant, based on continued
employment, and have a term of ten years from the date of grant assuming
continued employment. Vesting and exercisability accelerates upon achievement of
certain financial performance targets determined by the Board of Directors. If
all financial performance targets are met timely in accordance with parameters
as set by the Board in its sole discretion, 25% of the shares granted become
exercisable on the first anniversary date following the date of grant and, if
subsequent financial performance targets are met for both the first and second
fiscal years following the date of grant, a second 25% become exercisable three
years following the date of grant. If financial performance targets are met
consecutively for all three fiscal years following the date of grant, a third
25% become exercisable on the fourth anniversary date following the date of
grant and the final 25% become exercisable on the fifth anniversary following
the date of grant. Failure to achieve the specified target or targets for any
one fiscal year or consecutive fiscal years can be remedied by achievement of
the cumulative target in a succeeding fiscal year or years. Based on fiscal
1996, 1997 and 1998 performance, 1,048,280 shares were exercisable on September
30, 1998. An additional 1,475,000 options became exercisable on October 10,
1998. At September 30, 1998 and 1997, 287,500 and 810,000 shares were available
for grant, respectively.

     In October 1996, the Company adopted the 1996 Long Term Stock Option Plan
("the 1996 long-term Plan"). Under the terms of the plan, the Board of Directors
may grant non-qualified and incentive options, entitling employees to purchase
shares of the Company's common stock at the fair market value at the date of
option grant. A total of 1,800,000 shares of Class A Common Stock was reserved
for issuance under this plan. All options granted under the plan vest and become
fully exercisable six years following the date of grant, based on continued
employment, and have a term of ten years from the date of grant assuming
continued employment. Vesting and exercisability accelerates upon achieve-

ment of certain financial performance targets determined by the Board of
Directors. If all financial performance targets are met timely in accordance
with parameters as set by the Board in its sole discretion, 25% of the shares
granted become exercisable on the third anniversary date following the date of
grant and, if subsequent financial performance targets are met for both the
first and second years following the date of grant, a second 25% become
exercisable four years following the date of grant. If financial performance
targets are met consecutively for all three years following the date of grant, a
third 25% become exercisable on the fifth anniversary date following the date of
grant and the final 25% become exercisable on the sixth anniversary following
the date of grant. Based on fiscal 1997 and 1998 performance, 815,250 options
will be exercisable on February 24, 2000. At September 30, 1998 and 1997,
169,500 and 25,000 options to purchase common stock were available for grant.

     On April 4, 1997, the Company repriced certain stock options granted from
October 1995 through January 1997 under the 1991 Option Plan and the 1994
Long-Term Plan. In total, options to purchase 1,647,000 shares of common stock
were repriced at an exercise price of $23.875 per share. The original vesting
schedules and expiration dates associated with these stock options were also
amended to coincide with the stock option repricing date. These amounts have
been included as granted and canceled options during fiscal 1997 in the summary
activity table shown below.

     A warrant expiring December 1, 2000 to purchase 600,000 shares of Class A
Common Stock at $16.42 per share is held by IMS Health. The warrant was issued
in connection with the acquisition of Dataquest.

     The Company has chosen to continue applying APB No. 25 and related
interpretations in accounting for its plans. Accordingly, no compensation cost
has been recognized for the fixed stock option plans. Pursuant to the
requirements of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation", (FAS 123), the following are the pro forma net
income and net income per share for the years ended September 30, 1998, 1997 and
1996 had compensation cost for the Company's stock-based compensation plans been
determined based on the fair value at the grant date for grants under those
plans:

14--EMPLOYEE BENEFIT AND DEFERRED COMPENSATION PLANS 

The Company has a savings and investment plan covering substantially all
domestic employees. The Company contributes amounts to this plan based upon the
level of the employee contributions. In addition, the Company also contributes
fixed and discretionary amounts based on employee participation and attainment
of operating margins specified by the Board. Amounts expensed in connection with
the plan totaled $5.4, $4.6, and $3.2 million for the years ended September 30,
1998, 1997 and 1996, respectively.

15--GEOGRAPHIC DATA

The Company's consolidated revenues are generated primarily through direct sales
to clients by domestic and international sales forces, a network of independent
international distributors, and to a lesser extent by international joint
venture partners. The Company defines "Europe Revenues" as revenues attributable
to clients located in England and the European region and "Other International
Revenues" as revenues attributable to all other areas located outside of the
United States.

     European identifiable tangible assets consist primarily of the assets of
the European subsidiaries and include the accounts receivable balances carried
directly by the subsidiaries located in England, France and Germany. All other
European customer receivables are maintained by, and therefore are included as
identifiable assets of, the U.S. operations.

     For a description of the Company's revenue recognition policies, see Note
1--Significant Accounting Policies. AML revenues shown above of $512.8, $417.5,
and $318.7 million for fiscal 1998, 1997 and 1996, respectively, are recognized
as services and products are delivered, and the Company's obligation to the
client is completed over the contract period. Included in AML revenue are
catch-up adjustments also shown above for the fiscal years 1998, 1997, and 1996
of $24.9,

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

$18.2, and $22.1 million, respectively, to account for certain renewals.
Catch-up adjustments occur when there is a lag between the month that a contract
expires and the month that it is renewed. The Company continues to provide
services for a certain period of time after expiration, based on the Company's
historical experience that most clients who do not renew prior to expiration do
so on a retroactive basis. The Company recognizes no revenues, however, during
this period. When a client renews the service on a retroactive basis, the
Company records the previously unrecognized revenue as a catch-up adjustment.

18--SUBSEQUENT EVENT

On November 12, 1998, the Company's Board of Directors approved an agreement in
principle with IMS Health Inc. ("IMS Health") which owns 47.6 million or 47% of
the Company's Class A Common Stock to undertake a recapitalization of the
Company and facilitate a tax-free spin-off by IMS Health of its equity position
in Gartner Group Inc. to its shareholders. As part of the recapitalization, IMS
Health will exchange 40.7 million shares of Class A Common Stock for an equal
number of shares of new Class B Common Stock of the Company prior to the
spin-off. This new class of common stock will be entitled to elect at least 80%
of the Company's Board of Directors, but will otherwise be substantially
identical to existing Class A Common Stock. The Class B Common Stock will be
distributed to IMS Health shareholders in a tax-free distribution. IMS Health
will continue to hold 6.9 million shares of Class A Common Stock after the
spin-off. It is the intention of IMS Health to sell these shares within one year
of the spin-off, subject to certain conditions. In addition, the Company agreed
that it would pay a one-time special cash dividend of $300.0 million to its
shareholders of record immediately prior to the IMS Health spin-off. Further,
the Company also agreed that it would repurchase $300.0 million of its Class A
Common Stock on the open market after the spin-off. The exchange, spin-off and
special cash dividend are expected to be completed in the third quarter of
fiscal 1999, subject to approval by the IRS of the tax-free status of the
spin-off and approval of the recapitalization plan by the non-IMS Health
shareholders of the Company. The share repurchase program will commence after
the spin-off and is expected to be completed within one year.
