DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 relates to the following Registration Statements filed on Form S-8 (collectively, the “Registration Statements”):

1.  Registration Statement No. 333-53029, filed with the Securities and Exchange Commission on May 19, 1998, registering 750,000 shares of common stock, par value $0.01 per share (“Common Stock”), for the American Medical Alert Corp. 1997 Stock Option Plan;

2. Registration Statement No. 333-70626, filed with the Securities and Exchange Commission on October 1, 2001, registering 1,250,000 shares of Common Stock for the 2000 Stock Option Plan of American Medical Alert Corp.; and

3. Registration Statement No. 333-130811 filed with the Securities and Exchange Commission on December 30, 2005 registering 750,000 shares of Common Stock for the 2005 Stock Incentive Plan of American Medial Alert Corp.

On December 22, 2011, pursuant to the terms of the Agreement and Plan of Merger (the “Merger Agreement”), dated as of September 22, 2011, by and among American Medical Alert Corp. (“AMAC”), Tunstall Healthcare Group Limited (“Tunstall”), and Monitor Acquisition Corp., (“Merger Sub”) a wholly owned subsidiary of Tunstall, Tunstall completed its acquisition of AMAC via the merger of Merger Sub with and into AMAC, with AMAC continuing as the surviving company in the merger and becoming a wholly owned subsidiary of Tunstall (the “Merger”).  At the Effective Time of the Merger, each share of Common Stock, including shares of restricted stock, issued and outstanding immediately prior to the effective time (other than treasury shares of AMAC and any shares of Common Stock owned by Tunstall, Merger Sub or any wholly owned subsidiary of AMAC) was converted into the right to receive (i) an amount in cash, without interest, equal to $8.55, less the amount of any required withholding tax, and (ii) one contingent payment,  subject to and in accordance with a CPR Agreement, which provides for payments under certain circumstances relating to AMAC’s investment in Lifecomm LLC.

As a result of the Merger, AMAC has terminated all offerings of its securities pursuant to its existing registration statements, including the Registration Statements. In accordance with an undertaking made by AMAC in the Registration Statements to remove from registration, by means of a post-effective amendment, any securities which remain unsold at the termination of the offering, AMAC hereby removes from registration all shares of Common Stock registered but unsold under the Registration Statements.
