                 -----------------------------------------------

        ACQUISITION FOCUSES ON FAST-GROWING NUCLEAR PHARMACY BUSINESS

DUBLIN, OHIO, AND WOODLAND HILLS, CALIFORNIA, JUNE 14, 2002 - Cardinal Health,
Inc. (NYSE: CAH), the leading provider of products and services supporting the
health care industry, and Syncor International Corporation (Nasdaq: SCOR), the
leading provider of nuclear pharmacy services, announce a definitive agreement
allowing Cardinal Health to acquire Syncor for approximately $1.1 billion. This
acquisition provides Cardinal Health with a leadership presence in the
high-growth and profitable nuclear pharmacy business and advances its strategy
of expanding the breadth of offerings it provides to health care customers.

The acquisition of Syncor is a stock-for-stock deal in which Syncor will become
a wholly owned subsidiary of Cardinal Health. Terms of the definitive agreement
call for Syncor shareholders to receive .52 Cardinal Health common shares for
each outstanding share of Syncor common stock, with Cardinal Health issuing an
aggregate of approximately 14 million common shares on a fully diluted basis.
The transaction is intended to be tax-free to the holders of Syncor common
stock. Cardinal Health will also assume Syncor's debt, which, net of cash,
totaled $202 million as of March 31, 2002. The acquisition is expected to be
completed by the end of 2002, subject to regulatory clearance, approval by
Syncor shareholders, and other customary conditions. Cardinal Health expects the
completed acquisition to be accretive to its earnings within the first year.

Syncor pioneered the concept of centralized nuclear pharmacy services, also
known as radiopharmacy, in 1974. It compounds and dispenses radiopharmaceuticals
for diagnostic and

therapeutic use for oncology and heart disease applications, among others. These
medicines also allow physicians to investigate the function of various organs
and treat illness without the risk or expense of surgery. Syncor's net sales
grew 23 percent in FY 2001 to $775 million, 73 percent coming from the nuclear
pharmacy business.

Syncor also operates a network of imaging centers, a business it announced
earlier this year that it did not intend to further expand. Syncor has decided
to exit this business either before or shortly following the completion of the
acquisition. Syncor also announced earlier this year that it was rationalizing
its international operations. Cardinal Health will accelerate that
rationalization following the acquisition.

"Syncor is a leader in radiopharmacy services and is a tremendous fit with
Cardinal Health. With Syncor, we will have a strong core nuclear pharmacy
service we can offer our provider customers and also an attractive
commercialization and logistics solution for manufacturers of complex
pharmaceuticals," said Robert D. Walter, chairman and chief executive officer of
Cardinal Health. "This combination expands Cardinal Health's breadth of
offerings, including our complementary Central Pharmacy Services business, and
provides another opportunity to introduce our products and services to new
customers and more effectively deliver value to health care providers."

"Cardinal Health's resources and leadership position in health care will be a
tremendous asset for Syncor," said Monty Fu, chairman and founder of Syncor. "As
a result of our partnership, the combined relationships with providers and
manufacturers as well as the capability to offer more nuclear pharmacy products
and services to customers will far exceed what either company could accomplish
independently."

"Syncor's commitment to service and professionalism, bias towards action, and
business innovation are the reasons why we are so successful in the
radiopharmacy business," said Robert G. Funari, president and chief executive
officer, Syncor International Corporation. "These are characteristics we share
with Cardinal Health so we are excited to build on our considerable success
through this new association."
