           VII.   BACK-UP WITHHOLDING; SUBSTITUTE FORM W-9; FORMS W-8

                    U.S. STOCKHOLDERS -- SUBSTITUTE FORM W-9

     U.S. federal income tax law requires that a holder whose tendered IMS
Health Incorporated ("IMS Health") shares are accepted for exchange must provide
the exchange agent (as Payor) with his or her correct taxpayer identification
number ("TIN") on the Substitute Form W-9 included herein, which, in the case of
a holder who is an individual, is his or her social security number. IF THE
EXCHANGE AGENT IS NOT PROVIDED WITH THE CORRECT TIN OR AN ADEQUATE BASIS FOR
EXEMPTION, THE HOLDER MAY BE SUBJECT TO A PENALTY IMPOSED BY THE INTERNAL
REVENUE SERVICE ("IRS").

     Exempt holders (including, among others, corporations and financial
institutions) are not subject to these backup withholding and reporting
requirements. See the section entitled "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional instructions.

     To prevent backup withholding, each tendering holder must provide his or
her correct TIN by completing the Substitute Form W-9 included herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN) and that (1) the holder is exempt from backup withholding, (2) the holder
has not been notified by the IRS that he or she is subject to backup withholding
as a result of the failure to report all interest or dividends or (3) the IRS
has notified the holder that he or she is no longer subject to backup
withholding. If the certificate(s) representing IMS Health shares are in more
than one name or are not in the name of the actual owner, consult the guidelines
for information on which TIN to report. If you do not have a TIN, consult the
guidelines for instructions on applying for a TIN, check the box of the
Substitute Form W-9

                                        10


(Part 3) indicating that you have applied for and are awaiting receipt of your
TIN, write "Applied For" in the space for the Social Security number or Employer
Identification Number and complete the Certification of Payee Awaiting Taxpayer
Identification Number in order to avoid backup withholding. Notwithstanding that
there is a check in the box indicating that you have applied for and are
awaiting receipt of your TIN, you have written "Applied For" in the space for
the Social Security number or Employer Identification Number and the
Certification of Awaiting Taxpayer Identification Number is completed, the
exchange agent will withhold 30% of the cash payments equal to or in excess of
$20 made in lieu of fractional shares of Cognizant Technology Solutions
Corporation ("Cognizant") common stock pursuant to the exchange offer, and if
the TIN is provided within 60 days, such amount will be refunded. Backup
withholding is not an additional tax. Rather, the federal income tax liability
of persons subject to backup withholding will be reduced by the amount of tax
withheld. If backup withholding results in an overpayment of taxes, a refund may
be obtained from the IRS.

     Holders of shares of IMS Health common stock who acquired their shares at
different times may have different tax bases in their IMS Health shares, and
should consult their tax advisors as to the possibility of identifying the
specific IMS Health shares surrendered in the exchange offer in order to
establish the tax basis of the shares of Cognizant common stock issued in
exchange for IMS Health shares surrendered.

                       NON-U.S. STOCKHOLDERS -- FORMS W-8

     Tendering non-U.S. stockholders must complete and submit to the exchange
agent, instead of the Substitute Form W-9, a Form W-8BEN (Certificate of Foreign
Status of Beneficial Owner for United States Tax Withholding), a Form W-8ECI
(Certificate of Foreign Person's Claim for Exemption From Withholding on Income
Effectively Connected With the Conduct of a Trade or Business in the United
States), a Form W-8EXP (Certificate of Foreign Government or Other Foreign
Organization for United States Tax Withholding) or a Form W-8IMY (Certificate of
Foreign Intermediary, Foreign Partnership, or Certain U.S. Branches for United
States Tax Withholding) (each a "Form W-8" and, collectively, "Forms W-8"), as
applicable. Forms W-8 and related instructions may be obtained from the exchange
agent. If you are a non-U.S. stockholder, you should consult your tax advisor as
to which Form (s) W-8 you should complete. A TENDERING NON-U.S. STOCKHOLDER WHO
DOES NOT COMPLETE, SIGN AND RETURN THE APPROPRIATE FORM W-8 TO THE EXCHANGE
AGENT WILL BE SUBJECT TO U.S. FEDERAL BACKUP WITHHOLDING EQUAL TO 30% OF THE
CASH PAYMENTS EQUAL TO OR IN EXCESS OF $20 MADE IN LIEU OF FRACTIONAL SHARES OF
COGNIZANT COMMON STOCK PURSUANT TO THE EXCHANGE OFFER. Backup withholding is not
an additional tax. Rather, the federal income tax liability of persons subject
to backup withholding will be reduced by the amount of tax withheld. If backup
withholding results in an overpayment of taxes, a refund may be obtained from
the IRS.

willful neglect.

properly include any portion of an includible payment for interest, dividends,
or patronage dividends in gross income, such failure will be treated as being
due to negligence and will be subject to a penalty of 5% on any portion of an
underpayment attributable to that failure unless there is clear and convincing
evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING -- If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION -- Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
