Dear Xx. Xxxxx and Xx. Xxxxxxx:
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
