LabCorp first to bring New Genomic-based, Non-Invasive Colorectal Cancer
Test to Market

Only lab applying EXACT Sciences' proprietary DNA-based
technology

Burlington, NC, December 6, 2001 - Laboratory Corporation of America-
Registered Trademark- Holdings (LabCorp-Registered Trademark-) (NYSE:
LH) today announced that PreGen-26-Trademark- - a DNA-based colorectal
cancer test - is now available through its nationwide network to physicians
and their patients.  The test is based on EXACT Sciences Corporation's
(NASDAQ: EXAS) proprietary genomics-based technology.

PreGen-26 targets Hereditary Non-Polyposis Colorectal Cancer (HNPCC) -
an inherited predisposition to develop colorectal cancer.  People with this
syndrome have an 80 percent lifetime risk of developing the disease.

"LabCorp's offering of PreGen-26 reaffirms our commitment to apply today's
knowledge of genetics to yield improved clinical information for physicians
and patients," said LabCorp Chairman and CEO Thomas P. Mac Mahon.
"We are extremely pleased to collaborate with EXACT Sciences in this
exclusive national partnership to make this test and future tests available."

Don Hardison, President and CEO of EXACT Sciences commented, "Our
partnership with LabCorp represents the execution of EXACT Sciences' long-
term strategic plan to provide industry leaders, like LabCorp, the tools to
successfully commercialize our technologies.  We are looking forward to
additional ventures with LabCorp that will help us achieve our mission of
using genomics to eradicate the mortality associated with cancer."

PreGen-26 is not a predictive test for colorectal cancer - it is intended to
detect the presence of actual disease. The test is expected to become a part
of HNPCC patients' routine surveillance examinations, helping to detect
colorectal cancer earlier when treatment is most effective.  In active
colorectal cancer, DNA from tumors is shed into the colon and carried out of
the body in stool. LabCorp will provide a non-invasive, patient-friendly
method for patients to collect whole stool samples in the privacy of their
home. The sample will then be analyzed by LabCorp using EXACT Sciences'
proprietary, genomics-based technology to isolate and analyze the DNA shed
from colorectal tumors. Following the analysis, LabCorp will send the test
results to the patient's physician for use in connection with future
monitoring and treatment.

Colorectal cancer is second only to lung cancer in the number of deaths it
causes annually among Americans.  About 139,000 Americans will be
diagnosed with colorectal cancer each year and 57,000 people will die from it,
according to the American Cancer Society.  The American Cancer Society
also estimates that 90 percent of people who are diagnosed with colorectal
cancer would survive if the disease were detected earlier.

About EXACT Sciences Corporation
EXACT Sciences Corporation is an applied genomics company that has
developed proprietary technologies that may be used for the early detection of
several common cancers.  EXACT Sciences has selected colorectal cancer as
the first application of its technologies. Colorectal cancer is the most deadly
cancer among non-smokers, and is curable if detected early.  Despite the
availability of colorectal cancer screening and diagnostic tests for more than
20 years, the rate of early detection of colorectal cancer  remains low.
EXACT Sciences believes its genomics-based technologies will enable early
detection of colorectal cancer so that more people can be effectively
treated.  Founded in 1995, EXACT Sciences is based in Maynard, Mass.
Detailed information on EXACT Sciences can be found on the World Wide
Web at www.exactsciences.com.
