EXACT SCIENCES AND LABORATORY CORPORATION OF
AMERICA SIGN LICENSING AGREEMENT FOR TESTING
SERVICES BASED UPON EXACT SCIENCES' GENOMICS-
BASED TECHNOLOGIES

Burlington, NC - July 11, 2001 - EXACT Sciences Corporation
(NASDAQ: EXAS) and Laboratory Corporation of America-Registered
Trademark- Holdings (LabCorp-Registered Trademark-) (NYSE:LH)
announced today that they have signed an agreement for the licensing of
EXACT Sciences' proprietary genomics-based technologies to LabCorp.
Under the agreement, for a specified period of time, LabCorp will be the
only national clinical laboratory to offer testing services based on certain
of EXACT Sciences' proprietary technologies for the detection of
colorectal cancer.  As part of the licensing arrangement, EXACT Sciences
will receive an upfront payment and licensing fees on the amount of
testing performed.

LabCorp will utilize its specialty sales force to offer testing for the
detection of colorectal cancer based on EXACT Sciences' technologies.
The first testing services offered by LabCorp using these technologies will
be to detect the presence of cancer in those patients who are
predisposed to a syndrome known as Hereditary Non-Polyposis
Colorectal Cancer (HNPCC).  EXACT Sciences recently introduced its
PreGen-26-Trademark- test for the HNPCC market, which is based on
the same proprietary genomics-based technology as that licensed to
LabCorp.  Over time, EXACT Sciences and LabCorp expect to offer
broader testing services based on EXACT Sciences' proprietary
genomics-based technologies to the larger high-risk and average-risk
populations.

"We are extremely pleased to be working with LabCorp on the
commercialization of the technologies that form the basis of our PreGen-
Trademark- tests," said Don Hardison, EXACT Sciences' President and
CEO.  "LabCorp is a pioneer in offering DNA-based molecular testing
services, and we cannot think of a better partner to help us introduce our
proprietary genomics-based technologies into the national marketplace.
With LabCorp's experience in esoteric and molecular testing, as well as
its extensive distribution network, we believe we will have a significant
impact on reducing mortality from colorectal cancer by expanding the
availability of our genomics-based technologies to detect cancer."

"We are confident that this is the beginning of a long and mutually
beneficial relationship," stated Tom Mac Mahon, LabCorp's Chairman and
CEO.  "We believe that the future of the clinical laboratory business lies in
the area of genomics-based technologies and are therefore very excited
to be working with a pioneer such as EXACT Sciences.  The signing of
this agreement is a fundamental part of LabCorp's strategic plan to be the
leading provider of esoteric testing services in the country."

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.   Information on EXACT Sciences also is
available at 866-IR4-EXAS.
