LABORATORY CORPORATION OF AMERICA-REGISTERED TRADEMARK-ANNOUNCES
ANNOUNCES DEFINITIVE AGREEMENT TO ACQUIRE DYNACARE INC.

Burlington, NC, and Dallas, TX, May 9, 2002 - Laboratory Corporation of
America-Registered Trademark- Holdings (LabCorp-Registered Trademark-)
(NYSE: LH), a national clinical laboratory with 2001 revenues of $2.2 billion,
and Dynacare Inc. (Nasdaq: DNCR; TSE: DNA), a leading independent provider
of laboratory testing in North America, today announced that they have entered
into a definitive agreement under which LabCorp will acquire all of the
outstanding shares of Dynacare for approximately $480 million in cash and
stock. In addition, LabCorp will assume approximately $205 million in
Dynacare debt in conjunction with the closing of the transaction.

The acquisition is anticipated to be immediately accretive to LabCorp's EPS
in 2002, and to adjusted earnings before interest, taxes, depreciation and
amortization (EBITDA) in the first full year.  LabCorp expects to realize an
estimated $45 million in annual cost savings synergies by year-end 2004.

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 $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 $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.

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, with 24 central laboratories, two esoteric laboratories, 115 rapid
response labs and 302 patient service centers, provides clinical laboratory
testing services in 21 states and two Canadian provinces. Dynacare, a
portfolio company of private equity firm GTCR Golder Rauner, L.L.C., had
2001 revenues of approximately $238 million (based on U.S. GAAP) and has
approximately 6,300 employees.

"We are excited to have reached an agreement with Dynacare,"
said Thomas P. Mac Mahon, LabCorp chairman and chief executive officer.
"This transaction will enable LabCorp to provide more physicians and their
patients with improved access to an expanded menu of leading-edge testing
technologies.  The merger will also expand our ability to service managed care
and hospital customers and to achieve greater operating efficiencies.
Clearly, the combination with Dynacare will help us achieve these objectives."

Mr. Mac Mahon also said, "We are pleased that Harvey A. Shapiro, chairman
and chief executive officer of Dynacare, has agreed to remain with the Company
and become president of the Canadian operations, in addition to participating
in the integration of the two companies."

Mr. Shapiro said, "We are very excited about the opportunities this
combination presents and believe this transaction offers our shareholders fair
value for their Dynacare investment. Further, joining the strengths of
Dynacare and LabCorp will create a more dynamic company in a swiftly
changing and ever more demanding health care marketplace."

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.

LabCorp will host a conference call with investors to discuss the transaction
on May 9, 2002 at 9:00 A.M. ET. A live webcast of the call will be available
online at www.labcorp.com or at www.streetevents.com beginning at 9:00 A.M.
