        CARDINAL HEALTH AND SYNCOR ANNOUNCE AMENDED MERGER AGREEMENT

     o   Exchange Ratio Lowered to 0.47 Cardinal Health Common Shares per
         Syncor Share

     o   Merger to Create Leading U.S. Nuclear Pharmacy Services Business

     o   Syncor Reaches Agreements with Department of Justice and Staff of
         Securities and Exchange Commission

     o   Extensive Due Diligence Confirms Quality of Core Operations

DUBLIN, OHIO and WOODLAND HILLS, CALIFORNIA - December 4, 2002 - Cardinal
Health, Inc. (NYSE: CAH) and Syncor International Corporation (Nasdaq:
SCOR) today announced that they have amended the June 14, 2002 merger
agreement pursuant to which Cardinal Health will acquire Syncor in a
stock-for-stock merger transaction. Under the terms of the revised
agreement, Syncor stockholders will receive 0.47 of a Cardinal Health
common share in exchange for each outstanding share of Syncor common stock.
The original merger agreement had provided for a 0.52 exchange ratio.

Cardinal Health further announced it is satisfied that it can move forward
with the acquisition in a manner that is consistent with its high
standards. Following the acquisition, Syncor's core domestic nuclear
pharmacy business and the Central Pharmacy Services (CPSI) business of
Cardinal Health will be combined, creating a leading provider in the fast
growing and profitable nuclear pharmacy services business and furthering
Cardinal Health's strategy of expanding its breadth of offerings to health
care customers.

Syncor also announced today that it had reached separate agreements with
the U.S. Department of Justice (DOJ) and the staff of the U.S. Securities
and Exchange Commission (SEC) related to the previously disclosed improper
payments made by Syncor subsidiaries in certain foreign countries.

"We have taken the steps and the time necessary to be fully satisfied that
we can move forward with the acquisition of Syncor consistent with Cardinal
Health's high standards of conduct," said Robert D. Walter, chairman and
chief executive officer of Cardinal Health. "As a result of our further
extensive domestic and international due diligence, which included
investigations conducted by outside legal and forensic accounting teams,
and the separate investigation conducted by the Syncor Special Committee,
the issues have been identified and dealt with decisively. We believe that
these actions, in conjunction with the agreements reached with the
Department of Justice and SEC, bring these issues to closure and give us
the confidence that Cardinal Health shareholders will be protected as we
move forward to complete the acquisition."

Upon completion of the acquisition, the Syncor operations will be
integrated with Central Pharmacy Services (CPSI) to become the Nuclear
Pharmacy Services business in the Pharmaceutical Technologies and Services
(PTS) group of Cardinal Health. "Both Cardinal Health's CPSI business and
Syncor's core domestic nuclear pharmacy business continue to deliver strong
performance," said George Fotiades, who oversees the PTS group. "Syncor's
domestic nuclear pharmaceutical operations represent an attractive fit with
our existing nuclear pharmacy services offering, and will enhance our
relationships with pharmaceutical manufacturers and biotech companies."
Syncor will continue with previously announced plans to sell its imaging
business and further rationalize its international operations.

The agreement Syncor reached with the DOJ requires Syncor Taiwan, Inc., a
subsidiary of Syncor, to plead guilty to one count under the Foreign
Corrupt Practices Act (FCPA) and to pay a fine of $2 million relating to
improper payments to employees of state-owned health care facilities in
Taiwan. The agreement with the DOJ is subject to court approval of the plea
agreement. The agreement Syncor reached with the staff of the SEC requires
Syncor, without admitting or denying any findings, to consent to the entry
of a cease and desist order prohibiting further violations of the FCPA and
to pay a civil penalty of $500,000 relating to certain activities of
Syncor's foreign subsidiaries. Syncor's board of directors will be required
to appoint an independent consultant to review and make recommendations to
improve Syncor's internal controls, record-keeping and financial reporting
policies and procedures as they relate to the anti-bribery provisions of
the FCPA. The agreement with the staff of the SEC requires approval by the
Securities and Exchange Commission and the civil penalty is subject to
court approval.

"I am pleased that we can now focus on merging our domestic operations with
Cardinal Health to create a world-class nuclear pharmacy services
offering," said Robert Funari, president and chief executive officer,
Syncor International.

Cardinal Health and Syncor currently expect to complete the transaction in
December 2002 or January 2003, with Cardinal Health issuing approximately
13 million shares to Syncor stockholders. Completion of the acquisition
remains subject to customary conditions including, among others, approval
of the revised merger agreement by the Syncor stockholders. As previously
announced, Syncor will convene a stockholders meeting on December 6, 2002,
for the sole purpose of adjourning the meeting to a later date so that
additional information can be provided to stockholders. Syncor expects to
mail additional information to its stockholders regarding the revised
merger agreement, a new stockholders meeting date and other important
information as soon as the materials are filed and cleared by the
corporation finance division of the SEC.
