CERNER ACQUIRES ADAC HEALTHCARE INFORMATION SYSTEMS

KANSAS CITY, MO. - NOVEMBER 21, 2000 - Cerner is pleased to announce the
completion of its previously announced acquisition of ADAC Health Care
Information Systems (HCIS) from ADAC Laboratories for approximately $6
million in cash. ADAC HCIS produces information and image management
solutions for radiology departments. This acquisition is expected to be
non-dilutive in 2001 and is expected to contribute positively to earnings in
2002.

"There is significant synergy between ADAC HCIS and Cerner in terms of our
cultures, shared architectures and committment to radiology as one of the
most vital diagnostic centers of healthcare," said Neal L. Patterson, Cerner
chairman and chief executive officer. "This acquisition broadens our market
presence and enhances our knowledge capital in radiology. These additional
footprints within the radiology segment further Cerner's mission to make
healthcare smarter, safer and more efficient."

"In addition to the many clients of both ADAC HCIS and Cerner, we welcome
more than 125 new clients to Cerner and believe they will benefit from our
industry-leading client service, commitment to innovation and continued
support for QuadRIS-TM- and MARS-TM-," said Patterson. "These clients
represent some of the most prestigious and innovative healthcare
organizations in America. Cerner will deliver the much-anticipated QuadRIS
upgrade planned for spring 2001. While the functionality of QuadRIS and
Cerner's world-class radiology solution, RadNet-Registered Trademark-, will
merge over time, Cerner will provide a smooth technology and financial
upgrade path for these products."

"Clinical imaging is a critical component of the electronic medical record
and plays an increasing role in the diagnostic and therapeutic treatment of
patients," said Patterson. "In fact, the marketplace for PACS (picture
archiving and communications systems) image management solutions is growing
at three times the rate of the radiology information systems market. Cerner
will integrate specific, proven ADAC HCIS PACS technology from the Envol
suite of image management products into the HNA Millennium platform to
provide the most complete and integrated radiology offering in the world."

"The experience, knowledge and client service mentality of the staff at ADAC
HCIS complements Cerner's world-class team of radiology experts," said Trace
Devanny, president of Cerner. "We will maintain an office in Houston for
these new Cerner associates and look forward to merging our visions for
transforming healthcare through product innovation in radiology."
