Section 8 - Other Events

Item 8.01 Other Events.

As previously reported, multiple purported shareholder class actions relating to the transactions contemplated by the Agreement and Plan of Merger, dated as of February 13, 2011, among the Emergency Medical Services Corporation (the “Company”), CDRT Acquisition Corporation and CDRT Merger Sub, Inc. (the “Merger Agreement”) have been filed in state court in Delaware and federal and state courts in Colorado against the Company, its directors and other parties. These actions seek unspecified damages and equitable relief, including an injunction halting the merger contemplated by the Merger Agreement or rescission of the merger, as applicable. On May 9, 2011, the plaintiffs in the consolidated Delaware action filed a notice with the Delaware Court of Chancery withdrawing the motion for a preliminary injunction they had filed on April 21, 2011; there is now no pending motion for a preliminary injunction in any of the actions.
