AGREEMENT TO ACQUIRE TRIAD HOSPITALS, INC. FOR $54 PER SHARE IN CASH

FRANKLIN, Tenn.& PLANO, Texas — (BUSINESS WIRE) — March 19, 2007 — Community Health Systems, Inc. (NYSE: CYH) (“CHS”) and Triad Hospitals, Inc. (NYSE: TRI) (“Triad”) today announced that they have entered into a definitive merger agreement pursuant to which CHS will acquire Triad for $54 per share in cash, or approximately $6.8 billion, including $1.7 billion of existing indebtedness. The merger will create the largest publicly traded hospital company in the United States. The combined company would own or operate approximately 130 hospitals in 28 states, with a total bed count of more than 18,700.

The merger agreement was unanimously approved by the Board of Directors of CHS. Triad’s Board of Directors, on the unanimous recommendation of a Special Committee composed entirely of disinterested directors, has approved the agreement and recommends that Triad stockholders approve the merger. All disinterested members of the Board voted in favor of the agreement, with two inside directors abstaining.

The acquisition is subject to certain closing conditions including approval by Triad’s stockholders, antitrust clearance and other regulatory approvals, and is expected to close in the third quarter of 2007. There is no financing condition to the consummation of the transaction. CHS has received financing commitments from Credit Suisse, Wachovia Capital Markets LLC, and certain of their affiliates. “This is a strategic growth opportunity for CHS,” said Wayne T. Smith, Chairman, President and CEO of CHS. “This deal will substantially increase CHS’s overall scale and enhance its geographic diversity. The two companies have similar values and we are excited about the 54 Triad hospitals and the addition of six new states to our portfolio. This acquisition complements our rural strategy by adding mid-size markets in great locations and we look forward to working with the talented and experienced management professionals throughout the Triad organization.”

“The transaction with CHS validates Triad’s strategy and I am proud of the value this brings to our shareholders. We look forward to working to ensure a smooth transition for our communities,” said James D. Shelton, Chairman and CEO of Triad.

Triad has terminated its previous merger agreement with a group led by affiliates of CCMP Capital Advisors and GS Capital Partners. In accordance with the terms of the original merger agreement, Triad paid a termination fee to the original purchaser under such agreement.
