BURLINGTON, NC, JUNE 10, 1998 - Laboratory Corporation of America-Registered

"We are pleased to have successfully completed this important acquisition of a
major laboratory in the Delaware marketplace," said Richard L. Novak,

excellent strategic combination for LabCorp, expanding our coverage not only
in Delaware, but also sections of southeastern Pennsylvania and southern New
Jersey.  Medlab has long been a respected regional laboratory with a loyal
base of physician clients.  The combination of Medlab with LabCorp allows us
to even better serve our clients and their patients by offering more
conveniently located patient service centers and on-site testing facilities.
It also allows us to broaden the array of testing services currently available
to area physicians, particularly in specialized fields such as molecular
biology, genetics, oncology and infectious disease, where LabCorp's Center for
Molecular Biology and Pathology offers leading-edge technologies important in
swift and effective patient care."
