      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.
