          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.
