The obligations of ThermoLase under the Units were assumed by Thermo Electron in connection with the merger of ThermoLase with Thermo Electron, which was effected on August 14, 2000, pursuant to an Agreement and Plan of Merger by and among Thermo Electron, ThermoLase and ThermoLase Acquisition Corporation dated as of December 14, 1999. During the Redemption Period, holders of Units may require Thermo Electron to redeem the Units for an amount of cash equal to $20.25 per Unit. Once the Redemption Period commences, holders of Units may surrender them for redemption at the offices of the transfer agent for the Units, American Stock Transfer & Trust Company, at the following address: 40 Wall Street, 46th Floor, New York, New York 10005, Attention: Reorganization Department. Pursuant to the terms of the Units, upon the expiration of the Redemption Period at 5:00 p.m., New York City time, on April 30, 2001, holders of Units who have not presented the Units for redemption will thereafter be entitled to receive 0.132 of a share of Thermo Electron common stock, $1.00 par value per share (the "Thermo Electron Common Stock") for each Unit that is not surrendered for redemption, and the redemption right applicable to such fractional share will cease to exist. As of March 1, 2001, based on the closing price per share of the Thermo Electron Common Stock on the New York Stock Exchange of $27.90, this fraction (0.132) of a share of Thermo Electron Common Stock was worth $3.68. As of March 2, 2001, there are 379,873 Units outstanding. Thermo Electron Corporation, as successor to ThermoLase Corporation Date: March 2, 2001 The Redemption Period described in this notice has not commenced. Holders of Units may not tender them to the Company prior to the commencement of the Redemption Period on April 3, 2001. Prior to the commencement of the Redemption Period, we will file a Schedule TO with the Securities and Exchange Commission. You should read the Schedule TO when it becomes available because it will contain important information regarding your rights under the Units. We will send record holders a copy of the Schedule TO. In addition, once it is filed with the Commission, you can obtain without charge the Schedule TO from Thermo Electron's Investor Relations Department by calling 781-622-1111 or at the Commission's web site at http:www.sec.gov.
