          SYNCOR MAILS PROXY MATERIALS FOR RECONVENED SPECIAL MEETING
                  TO VOTE ON ACQUISITION BY CARDINAL HEALTH

o     Special Meeting to be Reconvened on December 30, 2002

o     Implements Previously Announced Agreement with Department of Justice by
      Entering Syncor Taiwan Guilty Plea

o     Securities and Exchange Commission Approves Settlement Entered into by
      SEC Staff

WOODLAND HILLS, California, December 11, 2002 - Syncor International
Corporation (Nasdaq: SCOR) announced today that it has mailed supplemental
proxy materials to its stockholders for its special meeting of stockholders to
be reconvened on December 30, 2002 for the purpose of voting on the agreement
providing for the acquisition of Syncor by Cardinal Health (NYSE: CAH).

As previously announced, the meeting was adjourned on December 6, 2002 and
will be reconvened on December 30, 2002 at 2:00 p.m. PST, at the Warner Center
Hilton Hotel, 6360 Canoga Avenue, Woodland Hills, California. The meeting was
adjourned in order to give Syncor stockholders an opportunity to review
amendments to the original merger agreement dated June 14, 2002 and other
recent developments affecting Syncor. Supplemental proxy materials describing
the amended merger agreement and related matters were mailed today to all
Syncor stockholders as of the record date of October 9, 2002. A Cardinal
Health post-effective amendment relating to the supplemental proxy materials
was declared effective by the SEC yesterday.

Pursuant to a previously announced agreement with the U.S. Department of
Justice (DOJ) relating to improper payments made by Syncor subsidiaries in
certain foreign countries, Syncor's subsidiary, Syncor Taiwan, Inc., pled
guilty yesterday to a violation of the Foreign Corrupt Practices Act (FCPA)
and was sentenced by the court to pay a previously agreed to $2 million fine.

In addition, yesterday the Securities and Exchange Commission approved the
agreement announced on December 4, 2002 with the SEC Staff. In connection with
that agreement, the SEC issued an administrative order finding that Syncor
violated the anti-bribery, books-and-records, and internal-controls provisions
of the FCPA, ordering Syncor to cease-and-desist from such violations, and
requiring Syncor to retain an independent consultant to review and make
recommendations concerning the company's FCPA compliance policies and
procedures. Yesterday the SEC also filed a civil complaint against Syncor
alleging violations of the FCPA. Without admitting or denying the SEC's
charges, Syncor consented to the SEC's issuance of its administrative order
and to the entry of a final judgment in the lawsuit requiring it to pay a
$500,000 civil penalty. The civil penalty is subject to court approval.

The proposed acquisition of Syncor by Cardinal Health was first announced in
June 2002 and is a stock-for-stock merger in which Syncor will become a
wholly-owned subsidiary of Cardinal Health. As announced on December 4, 2002,
under the terms of the amended merger agreement, Syncor stockholders will
receive 0.47 of a Cardinal Health common share in exchange for each
outstanding share of Syncor common stock upon completion of the merger. The
acquisition remains subject to satisfaction of various conditions, including
approval of the amended merger agreement by Syncor stockholders. Syncor
expects that the merger transaction will close shortly after the Syncor
stockholder meeting if the amended merger agreement is approved by Syncor
stockholders and all other conditions to the merger have been satisfied.
