American Medical Alert Corp. Announces Settlement with Purported Class Action Plaintiffs Regarding Merger with Tunstall Healthcare Group Limited

LONG ISLAND CITY, New York, December 13, 2011: American Medical Alert Corp. (Nasdaq: AMAC), today announced that AMAC and other named defendants have entered into a memorandum of understanding (MOU) with plaintiffs’ counsel in connection with the purported class action lawsuits filed in the Supreme Court of the State of New York, County of Nassau and in the Supreme Court of the State of New York, County of Queens, in connection with its proposed merger with Tunstall Healthcare Group Limited.

As previously announced, on September 22, 2011, AMAC entered into an Agreement and Plan of Merger (the Merger Agreement) with Tunstall and its wholly owned subsidiary, Monitor Acquisition Corp. Under the terms of the MOU, AMAC will file a Current Report on Form 8-K supplementing certain disclosure in the definitive proxy statement filed by AMAC with the SEC on November 17, 2011 in connection with the merger. The MOU reflects the parties’ agreement to resolve the allegations by the settling plaintiffs against AMAC and other defendants in connection with the Merger Agreement and provides a release and settlement by the purported class of AMAC’s shareholders of all claims against AMAC and other defendants and their affiliates and agents in connection with the Merger Agreement. The MOU and settlement are contingent upon, among other things, approval of the Supreme Court of the State of New York, Queens County, the closing of the merger and further definitive documentation.

AMAC and the other named defendants continue to believe that each of the lawsuits filed in connection with its proposed merger with Tunstall are without merit.
