                     IMS HEALTH COMMENCING OFFER TO EXCHANGE
                   COGNIZANT TECHNOLOGY SOLUTIONS COMMON STOCK
                           FOR OUTSTANDING IMS SHARES

                IMS WILL EXCHANGE 0.309 SHARES OF COGNIZANT STOCK
                           FOR EACH IMS SHARE TENDERED

FAIRFIELD, CT and TEANECK, NJ, January 8, 2003 - IMS Health (NYSE: RX) and
Cognizant Technology Solutions (Nasdaq: CTSH) today jointly announced that IMS
is commencing its previously announced exchange offer to distribute IMS's
majority interest in Cognizant. Through the transaction, IMS will offer to
exchange 0.309 shares of its Cognizant common stock for each share of IMS common
stock tendered. The exchange ratio represents a premium of approximately 20
percent on the IMS share price, based on today's closing price of $16.64 per IMS
share on the NYSE and $64.55 per Cognizant share on the Nasdaq National Market.



        IMS will accept up to 36,540,129 tendered IMS shares in exchange for up
to all of the 11,290,900 Cognizant shares that it now owns. If more than
36,540,129 IMS shares are tendered, IMS will accept those shares on a pro-rata
basis under the terms described in the exchange offer.

         In order for the exchange offer to be completed, at least 27,400,000
IMS shares must be tendered. This is equivalent to the exchange of 75 percent of
the Cognizant stock owned by IMS.

         IMS believes that the exchange of shares under the offer will generally
be tax-free to exchanging stockholders and to IMS under Federal income tax laws.

         The exchange offer is scheduled to expire at 12 midnight EST, on
February 6, 2003. IMS shareholders will be receiving an Offering
Circular-Prospectus that provides complete details of the transaction.

         IMS has retained Georgeson Shareholder Communications Inc. as the
information agent for the transaction. To obtain copies of Offering
Circular-Prospectus and related documentation, or if you have questions about
the terms of the exchange offer or how to participate, you may contact the

IMS to serve as financial advisors and joint dealer managers on the transaction.
