     IMPROPER PAYMENTS BY SYNCOR IDENTIFIED THROUGH ONGOING DUE DILIGENCE
                  INTENDS TO CAREFULLY MONITOR THE SITUATION

DUBLIN, OHIO, NOVEMBER 6, 2002 -- Cardinal Health, Inc. (NYSE: CAH), confirmed
today that during its ongoing due diligence investigation of Syncor
International Corporation, the proposed acquisition of which was announced on
June 14, 2002, Cardinal Health recently discovered certain improper payments
that had been made in foreign countries by subsidiaries of Syncor. As soon as it
made these discoveries, Cardinal Health promptly informed Syncor of its findings
and Syncor immediately initiated an investigation.

Cardinal Health has since been informed of the results to date of the
investigation undertaken by a special committee formed by the Board of Directors
of Syncor to review these improper payments. Cardinal Health supports the
actions taken today by the Syncor Board in response to the results of the
special committee's ongoing investigation as well as the proactive decision by
Syncor to make full disclosure of its findings to the Department of Justice and
the Securities and Exchange Commission. Cardinal Health will continue to
carefully monitor the Syncor situation and assess the results of the Syncor
special committee's ongoing investigation as well as the results of Cardinal
Health's continuing due diligence review. Cardinal Health intends to use all
appropriate resources and spend the time necessary to complete its ongoing
comprehensive due diligence review in a deliberate manner.

Robert D. Walter, chairman and chief executive officer of Cardinal Health
stated: "Cardinal Health has an outstanding reputation for integrity in
operating our domestic and international businesses in an ethical and honest
manner. This reputation extends to our employees, suppliers and customers as
well as to the government agencies that come in contact with our businesses and
operations. We are committed to adhering to the principle of operating our
businesses consistent with all applicable legal obligations. While we continue
to believe that the strategic rationale for the acquisition of Syncor and its
nuclear pharmacy business has validity, any decision with respect to this
transaction must be made in the context of adhering to our core values and
protecting Cardinal Health's reputation."
