     IMS, COGNIZANT TECHNOLOGY SOLUTIONS ANNOUNCE FINAL PRORATION FACTOR IN
                                 EXCHANGE OFFER

FAIRFIELD, CT and TEANECK, NJ, February 12, 2003 - IMS Health (NYSE: RX) and
Cognizant Technology Solutions (Nasdaq: CTSH) today announced a final proration
factor of 21.115717 percent for the exchange offer to distribute IMS's majority
interest in Cognizant. The exchange offer, which was oversubscribed, expired at
12 midnight, EST on February 6, 2003. Under terms of the offer, IMS accepted
36,540,129 tendered IMS common shares in exchange for the 11,290,900 Cognizant
common shares that it owned.

Based on the final count by the exchange agent, 172,242,418 shares of IMS common
stock were tendered for exchange, including 215,417 shares held by eligible
"odd- lot" holders. Because the offer was oversubscribed, IMS accepted tendered
shares on a pro-rata basis in proportion to the number of shares tendered, based
on the 21.115717 percent proration factor. Shareholders who owned an "odd-lot,"
and who tendered all of their shares, were generally not subject to proration.

IMS commenced the exchange offer on January 9, 2003 and offered to exchange
0.309 shares of Cognizant stock for each share of IMS common stock tendered. The
exchange ratio represented a premium of approximately 17 percent on the IMS
share price, based on the closing prices of $16.48 per IMS share and $62.48 per
Cognizant share on February 6 - the date the offer expired.

Certificates for shares of Cognizant common stock, checks in lieu of fractional
Cognizant shares and shares of IMS common stock tendered but not accepted for
exchange will be delivered or mailed on or before February 14, 2003.
