 Re:     Developments at Syncor

I'm writing to update you on some recent developments with regard to our
previously-announced acquisition of Syncor. As part of our ongoing due diligence
review, we uncovered certain improper payments that Syncor has made in foreign
countries. We reported our findings immediately to Syncor, whose Board of
Directors contacted the proper government officials. I thought you might
like to see the two news releases that were distributed about this issue early
this morning, which are attached - one from Syncor and one from Cardinal Health.

While it is difficult to know yet what effect this development may have on our
plans to acquire Syncor, there are a few things I want to make clear:

*  While I am very disappointed with this development, it is an important
   example of how thoroughly we review the business operations, financial
   practices and other aspects of any new businesses we seek to acquire. And,
   frankly, ethics and cultural values are just as important to us as
   operational or financial issues. It's the reason we take our time with due
   diligence - we want to make sure we know everything we can about any business
   we want to make part of Cardinal Health.

*  We are continuing to monitor this situation carefully. Our agreement with
   Syncor is subject to a number of conditions that need to be satisfied before
   we close. At this time, we haven't concluded whether those conditions will be
   satisfied.

*  Our CPSI nuclear pharmacy business has been -- and continues to be -- an
   important part of our business strategy. The reason we want to further invest
   in this business is because we believe we can create better value for
   customers by expanding our core set of products and services. We remain
   committed to this business strategy.

Growth is an important part of our strategy at Cardinal Health. But, I can
assure that any acquisitions made in support of that growth must meet our
criteria for integrity and ethics.

This is a very complex situation and it is not a good idea to speculate on the
ultimate outcome.  This issue should not be discussed with customers, suppliers
or others outside of Cardinal Health. We'll keep you posted on any new
developments as they occur.

                     SYNCOR ANNOUNCES INTERNAL INVESTIGATION
                    REGARDING PAYMENTS IN OVERSEAS OPERATIONS


WOODLAND HILLS, CALIFORNIA, NOVEMBER 6, 2002 - Syncor International Corporation
(Nasdaq: SCOR) announced that a committee of outside directors, together with
special outside counsel, has been investigating the propriety of certain
payments made by overseas subsidiaries to customers in several foreign
countries, including Taiwan and China. To date, the investigation indicates that
some of the payments made to state-owned and private healthcare facilities may
have violated foreign and U.S. law, including the Foreign Corrupt Practices Act.
The investigation will cover Syncor's other overseas operations as well.

Representatives of Syncor have met with the Securities and Exchange Commission
and the U.S. Department of Justice to discuss the matter. Syncor intends to
cooperate fully with the authorities.

The Company also said that Mr. Monty Fu, Chairman of Syncor, and his brother,
Mr. Moses Fu, Director, Asia Region - Syncor Overseas LTD., have gone on paid
leave pending completion of an investigation into their involvement in the
payments. Monty Fu has also agreed to suspend his participation as a company
director pending completion of the investigation. The Board of Directors has
elected Mr. Bernard Puckett, a current director and Chair of the special
committee investigating the payments, as lead director of the Board.

The Company said that it takes full responsibility for the questionable payments
and is determined to uncover and correct any ethical or legal breaches that may
have been committed by any of its employees. The Company further emphasized that
it does not tolerate unethical or illegal behavior of any kind by any employee,
and that any employee found to have been responsible for any misdeeds will be
held fully accountable for his or her actions.

The payments were brought to Syncor's attention by Cardinal Health, Inc.
(NYSE:CAH), which learned of them in the course of its ongoing post-signing due
diligence relating to the previously announced planned merger of the two
companies. Syncor is working closely with Cardinal Health regarding the matter.
