EXHIBIT 99.1 Attention: Business Editors and Reporters - ----------------------------------------- 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.
