CERNER CORPORATION AGREES TO ACQUIRE ADAC'S HEALTH CARE INFORMATION SYSTEMS
BUSINESS

KANSAS CITY, Mo. & MILPITAS, Calif.--(BW HealthWire)--Oct. 24, 2000--Cerner
Corporation and ADAC Laboratories today announced that Cerner has agreed to
acquire ADAC's Health Care Information Systems (HCIS) business, excluding its
Cardiology Systems Group, for approximately $6 million cash.

The companies expect to complete the transaction in November 2000, pending
customary closing conditions and regulatory approval.

Cerner Corporation designs, develops, markets, installs and supports
information systems and content solutions for health organizations and
consumers. Cerner's HNA Millennium-Registered Trademark- suite of clinical,
management, and financial information systems is the most innovative and
integrated HIS package to span the continuum of care and deliver significant
benefits to healthcare organizations in terms of increased quality of care,
patient safety and operational efficiencies.

"ADAC's HCIS business, which produces information and image management solutions
for radiology departments, will provide a unique complement to our significant
radiology client base," said Neal L. Patterson, Chairman and chief executive
officer of Cerner. "Radiology is one of the most important diagnostic centers of
healthcare. The acquisition of ADAC's HCIS business will allow Cerner to broaden
our market presence in the radiology industry. A broad installed base of
clinical systems furthers our mission to increase healthcare efficiencies,
reduce medical error and improve appropriate clinical decision-making. We are
pleased to acquire the tremendous radiology capabilities of ADAC's HCIS and look
forward to meeting the evolving needs of its client base." "Cerner is proud of
our record of product innovation, combined with one of the highest levels of
client satisfaction and support in the healthcare technology industry,"
continued Mr. Patterson. "We look forward to serving the future needs of ADAC's
HCIS clients and sharing Cerner's vision for transforming health care with these
new clients. We believe this transaction will be non-dilutive financially in
2001 and will contribute positively to earnings in 2002."

R. Andrew Eckert, ADAC's chief executive officer, said, "We are pleased to
announce this agreement that we expect will be beneficial for all parties
involved. We believe that ADAC's HCIS customers will be well served by Cerner,
the leading provider of information technology in the health care industry. For
ADAC, this transaction will enable us to fully concentrate our resources on our
core businesses of nuclear medicine, positron emission tomography, and radiation
therapy products."

ADAC anticipates that it will take a charge of approximately $7 million (net of
tax) in its fourth fiscal quarter ended October 2, 2000, as a result of the
divestiture. This is in addition to the company's previously announced $2
million charge relating to the disposition of the Cardiology Systems Group,
which ADAC is selling to Camtronics, a subsidiary of Analogic Corporation. ADAC
expects to treat the HCIS business as a discontinued operation and to report an
estimated loss for the fourth quarter of approximately $.05 per share for HCIS,
separately from the results of its continuing operations.
