     SYNCOR AND CARDINAL HEALTH ANNOUNCE AMENDMENT TO MERGER AGREEMENT
                        TO EXTEND TERMINATION DATE

         WOODLAND HILLS, CALIFORNIA and DUBLIN, OHIO - November 22, 2002 -
Syncor International Corporation (Nasdaq: SCOR) and Cardinal Health, Inc.
(NYSE: CAH) today announced that they have agreed to amend their previously
announced merger agreement to extend the date after which either party may
unilaterally elect to terminate the transaction from December 31, 2002, to
January 15, 2003, subject to the terms of the merger agreement. The
amendment does not affect any terms of the merger agreement other than the
termination provisions.

         On November 21, 2002, Syncor and Cardinal Health announced that
Cardinal Health had initiated discussions with Syncor regarding the
possible modification of the terms of their previously announced merger
agreement under which Cardinal Health would acquire Syncor. The purpose of
the amendment to the termination date is to provide the parties with
further time to continue these discussions. 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. Cardinal Health
has previously stated that it has not yet concluded whether the conditions
to the transaction will be satisfied and that "there can be no assurance
that the transaction involving the acquisition of Syncor by Cardinal Health
will be completed."

         Syncor also today announced that it will be mailing to its
stockholders a supplemental notice of postponement of its special meeting
of stockholders to consider approval of the merger agreement with Cardinal
Health. As previously announced, the postponed meeting will now be held on
December 6, 2002. Syncor intends to convene the postponed special meeting
on December 6 solely for the purpose of adjourning the meeting to a later
time, date and place so that additional information can be provided to
stockholders.
