FOR IMMEDIATE RELEASE


Dynacare announces acquisition agreement with LabCorp


Toronto, May 9, 2002 - Dynacare Inc. (TSE: DNA; Nasdaq: DNCR) announced today it
has entered a definitive agreement with Laboratory Corporation of America
Holdings (LabCorp) under which LabCorp (NYSE: LH) will acquire all of the
outstanding shares of Dynacare for US$480 million. In addition, LabCorp will
assume approximately US$205 million in Dynacare debt in conjunction with the
closing of the transaction.

Under the terms of the agreement, which was unanimously approved by the boards
of both companies, LabCorp will acquire 100 percent of the outstanding shares of
Dynacare common stock for US$23.00 per share pursuant to a Plan of Arrangement
under Canadian Law. Under the Plan of Arrangement, each outstanding share of
Dynacare common stock will be exchanged for US$11.50 in cash and 0.1164 shares
of LabCorp common stock. LabCorp will issue approximately 2.4 million new common
shares in connection with the transaction, based on Dynacare's approximately
20.9 million diluted shares outstanding. The cash component of the transaction
will be funded by a combination of cash on hand, borrowings under LabCorp's
existing credit facility and a new bridge loan facility.

Dynacare has grown from its Canadian roots to become a major clinical laboratory
company in North America. In Ontario, the company operates in partnership with
Gamma NorthPeel and Bio-Science Laboratory, and in Alberta in partnership with
Kasper Medical Laboratories and MDS Laboratories. The deal does not affect these
partnerships, as the existing management teams will be retained to exercise
control over the company's operations in Canada.

"Dynacare remains committed to staying on the cutting edge of diagnostic
services in Canada, and we're proud that our reputation for quality and
efficiency prompted LabCorp to enter into this agreement," said Harvey Shapiro,
President and Chief Executive Officer of Dynacare. "Through LabCorp, new doors
will open for Dynacare and our partners. We will have access to advanced
technologies and resources, as well as strengthened capabilities to help us
improve our front-line lab services and growth prospects."

LabCorp is one of the world's leading clinical laboratory providers, with annual
revenues of US$2.2 billion in 2001. Each day, the company performs diagnostic
procedures on specimens from approximately 280,000 patients and is recognized as
an industry leader in introducing new diagnostic technologies, including its
being the first U.S. clinical lab company to fully embrace genomic testing.

"Diagnostic testing is entering into new and exciting areas, including genetic
analysis, but the start-up costs can often be exorbitant," said Mr. Shapiro. "As
a result of this transaction, the economies of scale are now in place for
Dynacare and its partners to adopt technological innovations as they emerge,
which translates into better overall medical care."

Under separate agreements, Dynacare's two largest shareholders and certain
officers and directors, who hold in the aggregate 48.2 percent of Dynacare's
outstanding common stock, will irrevocably undertake to vote their shares in



favor of the Plan of Arrangement and, under certain circumstances, sell their
shares to LabCorp if the Agreement is terminated or the Arrangement does not
close. The offer and the merger are conditioned on, among other things, a
favorable vote by the holders of two-thirds of Dynacare's outstanding common
shares and regulatory approvals in the U. S. and Canada.

Dynacare has also announced the termination of its joint ventures in Pittsburgh,
PA and Schenectady, NY. These terminations are expected to result in an after
tax charge of approximately $4.7 million in Dynacare's second quarter.

Through its integrated network of regional laboratory operations, Dynacare
provides innovative and trusted clinical laboratory services to its clients,
their patients and professional partners. In addition to being a leading
provider of laboratory services in Canada, Dynacare provides laboratory services
in 21 U.S. states. Further information about Dynacare can be obtained from the
Company's web site at www.dynacare.com.

Genetic and Esoteric Testing and Counseling, performs genetic reference work and
other esoteric testing for all Dynacare laboratories, as well as referring
