         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.

WOODLAND HILLS, California, December 4, 2002 - Syncor International

On December 4, 2002, the following letter was sent by Rod Boone to employees
of Syncor International Corporation:


                  LETTER FROM ROD BOONE TO SYNCOR EMPLOYEES

[GRAPHIC OMITTED]

December 4, 2002


Dear SPS Team Member:

As you may already know, Syncor and Cardinal Health have issued a joint
announcement indicating that we have successfully resolved certain questions
that had arisen between the companies regarding some improper payments made by
some of our overseas subsidiaries. As a result, the merger between our two
companies is now expected to be completed in late December or January.

At the same time, we have reached separate agreements with the Department of
Justice and the staff of the Securities and Exchange Commission that are
intended to settle the legal issues raised with those agencies in connection
with those payments.

Throughout this challenging period, that is now hopefully drawing to a close,
we have been and remain determined to protect the reputation of the thousands
of honest, ethical professionals like you who have made Syncor the
unquestioned leader in its field.

As a result of your dedication and continued focus, our SPS business is in the
process of turning in another excellent year. I continue to be extremely
excited about the merger with Cardinal Health and look forward to taking
advantage of the opportunities and synergies of merging with Cardinal Health
and CPSI. We will be able to offer our customers an even larger portfolio of
products and services as we join Cardinal Health and become part of the
Pharmaceutical Technologies and Services group headed by George Fotiades. I
have attached a note from Bob Walter to Cardinal Health employees for your
information.

Cardinal Health recently embarked upon a company-wide branding strategy
through which all of the divisions of the company will be going to market
under the Cardinal Health name effective January 1, 2003. As a result of this
initiative and the advantages this strategy will offer us in the marketplace,
after completion of the merger, the integrated Syncor-CPSI business will also
go to market under the Cardinal Health name.

I want to ask your support as we redouble our efforts towards successfully
integrating our pharmacy business with CPSI's. The more quickly and
efficiently we can complete the process, the better we can position the newly
combined business for future growth and value for our customers. The
integration teams will be seeking your critical feedback as we continue our
momentum in our integration activities and integration plans. I will continue
to keep you informed as we make progress.

In the meantime, I would like to thank you once again for your hard work and
loyalty. Your integrity and professionalism were--and continue to be--the key
to our efforts to protect and maintain Syncor's reputation for honesty,
quality, and service.


Warmest regards,


Rod Boone
