LABCORP-REGISTERED TRADEMARK- AND CELERA
DIAGNOSTICS TO COLLABORATE IN ALZHEIMER'S
DISEASE AND BREAST AND PROSTATE CANCER

BURLINGTON, NC, and ALAMEDA, CA - October 2, 2002
- - Laboratory Corporation of America-Registered Trademark-
Holdings (LabCorp-Registered Trademark-) (NYSE:LH) and
Celera Diagnostics, a joint venture between the Applied
Biosystems Group (NYSE:ABI), and the Celera Genomics
Group (NYSE:CRA) of Applera Corporation, today announced
an agreement to collaborate in establishing the clinical utility
of laboratory tests based on novel diagnostic markers for
Alzheimer's disease, breast cancer, and prostate cancer.  This
collaboration will support current and future disease
association studies at Celera Diagnostics that seek to identify
genetic markers associated with these important diseases.

The agreement provides LabCorp with exclusive access to
markers found to have clinical utility through the collaboration
for a defined time, and establishes Celera Diagnostics as a
preferred vendor to LabCorp for certain molecular diagnostic
products.  Terms of the agreement were not disclosed.

"LabCorp is delighted to collaborate with Celera Diagnostics, a
leader in genomic science, to introduce important new tests
targeting three common diseases with large, unmet diagnostic
needs," said Thomas P. Mac Mahon, Chairman and Chief
Executive Officer of LabCorp. "Not only will our scientists
contribute substantial scientific expertise to the validation
process, our national distribution network makes new
diagnostic services broadly available - offering the
opportunity to bring the promise of Celera's research to
practical reality."

"We are very pleased to have LabCorp as a partner in the
validation and commercialization of tests that incorporate
markers discovered at Celera Diagnostics," said Kathy
Ordo ez, President, Celera Diagnostics. "This arrangement
should help ensure that physicians and their patients obtain
rapid access to tests incorporating our future discoveries."

The disease association studies described in today's
announcement are being conducted by Celera Diagnostics as
part of the alliance with Abbott Laboratories to develop,
manufacture and market a broad range of in vitro molecular
diagnostic products for disease detection, disease progression
monitoring and therapy selection.  The alliance, announced in
June 2002, focuses on development of nucleic acid-based tests
for infectious and genetic diseases and cancer.  The two
companies are contributing current products to the alliance and
collaborating on the development of new products.
