LAIDLAW INTERNATIONAL ANNOUNCES FINAL RESULTS OF
SELF-TENDER OFFER

NAPERVILLE, Ill., August 11, 2006 — Laidlaw International, Inc. (NYSE:LI) today announced the final results of its modified “Dutch Auction” self-tender offer, which expired at 5:00 p.m., New York City time, on Monday, August 7, 2006.

Laidlaw accepted for purchase 15,557,985 shares of its common stock at a price of $26.90 per share. These shares represent approximately 16 percent of issued and outstanding shares as of August 7, 2006. Because Laidlaw is purchasing all of the shares tendered at or below $26.90, no proration is required.

“We are pleased with the successful completion of our tender offer,” said Kevin Benson, Laidlaw International president and chief executive officer. “It has enabled us to improve our capital structure and achieve leverage ratios which should enhance future shareholder value.”

Laidlaw, through the depositary, paid approximately $419 million for the shares accepted for purchase. With the completion of the tender offer, Laidlaw now has approximately 82.1 million shares of its common stock outstanding.

The tender offer is part of Laidlaw’s previously announced intention to use the proceeds from a new Term B facility to purchase up to $500 million of its common stock through share repurchases. With the successful completion of the tender offer, Laidlaw is authorized by its board of directors to make additional purchases of approximately $81 million of its common stock through open market purchases beginning on the 11^th business day after the expiration of the tender offer.

Laidlaw may conduct its share repurchases in the open market, in privately negotiated transactions, through derivative transactions and through purchases made in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934. The repurchase program does not require Laidlaw to acquire any specific number of shares and may be terminated at any time.

Morgan Stanley & Co. Incorporated and UBS Securities LLC served as dealer managers for the self-tender offer. D. F. King & Co., Inc. served as information agent and Mellon Investor Services served as the depositary. Any questions about the self-tender offer may be directed to the D.F. King at (212) 269-5550 (banks and brokerage firms) or (800) 290-6427 (all others toll free).
