                         CARDINAL HEALTH INITIATES
                    DISCUSSIONS WITH SYNCOR TO POSSIBLY
                          MODIFY MERGER AGREEMENT

         WOODLAND HILLS, CALIFORNIA and DUBLIN, OHIO - November 21, 2002 -
Syncor International Corporation (Nasdaq: SCOR) and Cardinal Health, Inc.
(NYSE: CAH) today announced that Cardinal Health has initiated discussions
with Syncor regarding the possible modification of the terms of their
previously announced merger agreement under which Cardinal Health would
acquire Syncor. While the parties intend to continue these discussions,
there can be no assurance that such discussions will result in the parties
agreeing to any revised terms.

         On November 6, 2002, Syncor announced that a newly established
special committee of three outside directors, together with outside
counsel, had been investigating the propriety of certain payments made by
certain of Syncor's international subsidiaries to customers in several
foreign countries. Syncor also announced that the special committee would
investigate Syncor's other foreign operations. Earlier this week, Syncor
announced, among other things, the special committee's findings based on
the information it had gathered to date.

         Based on the information Syncor has reviewed as of the date hereof
with respect to the matters currently under investigation by the special
committee, and subject to the terms of any resolution of these matters with
the Securities and Exchange Commission (SEC) and the United States
Department of Justice (DOJ), Syncor believes that the information it has
learned in the investigation would not result in Syncor's failure to
satisfy the conditions to the existing merger agreement. However, Syncor
cannot make a definitive determination as to the impact on the acquisition
pending completion of the investigation and resolution of Syncor's
discussions with the SEC and DOJ. Cardinal Health has not yet concluded
whether the conditions to the transaction will be satisfied and believes
that there can be no assurance that the transaction involving the
acquisition of Syncor by Cardinal Health will be completed. In light of the
foregoing, both companies believe that engaging in discussions regarding a
possible modification of certain of the terms of the existing merger
agreement is the best course of action at this time.

         The existing merger agreement provides for the acquisition of
Syncor by Cardinal Health in a stock-for-stock transaction in which Syncor
would become a wholly owned subsidiary of Cardinal Health. Terms of the
existing merger agreement call for Syncor stockholders to receive .52
Cardinal Health common shares for each outstanding share of Syncor common
stock.
