ITEM 5. OTHER EVENTS

Laboratory Corporation of America -Registered Trademark-Holdings
(LabCorp -Registered Trademark-)(NYSE:LH) announced the creation of an
exclusive, long-term strategic partnership to commercialize PreGen-
Plus-Trademark-, EXACT Sciences' proprietary, non-invasive technology
for the early detection of colorectal cancer in the average-risk
population.  As part of the agreement, in addition to certain royalty
fees, LabCorp could pay EXACT Sciences as much as $75 million in
upfront, milestone and performance-based payments for a five-year
exclusive license, followed by a non-exclusive license for the life of
the patents.  The introduction of Pre-Gen Plus, expected in the first
half of 2003, will mark the broadest commercial application of
discoveries made about the human genome to address a major healthcare
problem such as colorectal cancer-the most deadly cancer among non-
smokers in the United States.  There is no other DNA-based test
currently available for the early detection of cancer in an average-
risk population.


It is estimated that this year approximately 150,000 Americans will be
diagnosed with colorectal cancer and approximately 57,000 Americans
will die from the disease.  The American Cancer Society recommends that
the 80 million Americans who are over the age of 50 be screened
regularly for colorectal cancer, which, if detected at an early stage,
has a cure rate of more than 90 percent.  A majority of people,
however, avoid screening because of the inconvenience and discomfort
associated with certain currently available screening methods, with the
result that most colorectal cancer cases are detected at a later stage
when the cure rate is less than 50 percent.

EXACT SCIENCES AND LABCORP -REGISTERED
TRADEMARK- TO  OFFER PREGEN-PLUS -
TRADEMARK- CHANGING THE HEALTH CARE
LANDSCAPE WITH NON-INVASIVE, GENOMICS-
BASED COLORECTAL CANCER TECHNOLOGY

Exclusive Licensing Agreement to Make PreGen-Plus
Available to a Potential Market of 80 Million Americans; Will Mark the
First DNA-based Screening Method for Cancer in an Average-Risk Population

Maynard, Mass., and Burlington, N.C., - June 27, 2002 - EXACT
Sciences Corporation (NASDAQ: EXAS) and Laboratory Corporation
of America -Registered Trademark-) Holdings (NYSE:LH) (LabCorp-
Registered Trademark-) today announced the creation of an exclusive,
long-term strategic partnership to commercialize PreGen-Plus -
Trademark-, EXACT Sciences' proprietary, non-invasive technology for
the early detection of colorectal cancer in the average-risk population.
As part of the agreement, in addition to certain royalty fees, LabCorp
could pay EXACT Sciences as much as $75 million in upfront,
milestone and performance-based payments for a five-year exclusive
license, followed by a non-exclusive license for the life of the patents.
The introduction of PreGen-Plus, expected in the first half of 2003, will
mark the broadest commercial application of discoveries made about
the human genome to address a major healthcare problem such as
colorectal cancer - the most deadly cancer among non-smokers in the
United States.  There is no other DNA-based test currently available
for the early detection of cancer in an average-risk population.

It is estimated that this year approximately 150,000 Americans will be
diagnosed with colorectal cancer and approximately 57,000 Americans
will die from the disease.  The American Cancer Society recommends
that the 80 million Americans who are over the age of 50 be screened
regularly for colorectal cancer, which, if detected at an early stage, has
a cure rate of more than 90 percent.  A majority of people, however,
avoid screening because of the inconvenience and discomfort
associated with certain currently available screening methods, with the
result that most colorectal cancer cases are detected at a later stage
when the cure rate is less than 50 percent.


LabCorp's first payment to EXACT Sciences of $15 million was made
upon the signing of the agreement, and the second payment of $15
million will be made upon the commercial launch of PreGen-Plus,
which is expected in the first half of 2003.  Of the remaining $45
million, milestone payments from LabCorp totaling $30 million will be
based upon EXACT Sciences deliverables related to scientific
acceptance, reimbursement approval and technology improvements
and $15 million will be based upon the achievement of significant
revenue thresholds.  In addition to these payments, EXACT Sciences
will receive a royalty fee for each PreGen-Plus test performed by
LabCorp.  In conjunction with the partnership, EXACT Sciences has
issued to LabCorp a warrant to purchase 1,000,000 shares of EXACT
Sciences common stock, exercisable over the next three years at an
exercise price of $16.09.

 "The proprietary technology underlying the PreGen-Plus assay
creates a very accurate and patient-friendly test, and therefore
represents a significant step forward in the early detection of colorectal
cancer in the average-risk population," said Thomas P. Mac Mahon,
LabCorp's Chairman and CEO.  "We believe PreGen-Plus could be the
most important molecular test identified to date for the millions of
Americans who are candidates for colorectal cancer screening
annually."

Mr. Mac Mahon continued, "Our agreement with EXACT Sciences is
another example of LabCorp's pioneering leadership position in
molecular diagnostics and our ability to recognize the potential of DNA-
based testing.  EXACT Sciences brings that same visionary approach
in applying the discoveries of the human genome to create novel DNA-
based assays that address major healthcare problems.  We are
excited about combining our skills with EXACT Sciences' to improve
diagnostic testing for cancer."

"As the first DNA-based test that will be used for population-based
cancer screening, PreGen-Plus truly changes the molecular
diagnostics landscape," said Don Hardison, EXACT Sciences'
President and CEO.  "The scope of this partnership - both in economic
terms and, more importantly, in terms of lives saved - highlights the
power of applied genomics.  As a leader in bringing the knowledge of
the human genome to reality, EXACT Sciences is delighted to be
working with LabCorp, given its unique scale, expertise and
infrastructure, to make this important test widely available.   We are
confident that the fruits of our strategic relationship will result in greater
numbers of Americans being screened for the disease and the
prevention of many deaths from colorectal cancer."

PreGen-Plus works by isolating human DNA that is shed in the colon
everyday and carried out of the body in stool, and analyzing that DNA
for mutations associated with colorectal cancer.  PreGen-Plus is a
completely non-invasive, patient-friendly technology that requires no
dietary modification or bowel preparation.   The simple process
involves collecting a single stool sample in the privacy of a patient's
own home, and shipping the sample in a supplied container and
packaging materials to LabCorp's facilities for analysis.  Following the
analysis, LabCorp will send the test results to the patient's physician
for use in connection with future monitoring and treatment.

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.
