(NASDAQ:SPLI) subsidiary private at a new cash price of $17.50 per share. Thermo Electron expects to initiate the cash tender offer by November 16, 2001, for any and all outstanding shares of Spectra-Physics common stock held by minority shareholders. On September 26, 2001, Thermo Electron announced that it was delaying the commencement of its tender offer for shares of Spectra-Physics while it analyzed the impact on Spectra-Physics of the worsening economic conditions following the September 11 events. As of today, Thermo Electron owned approximately 80 percent of Spectra-Physics common stock. The goal of the tender offer is to bring Thermo Electron's equity ownership in Spectra-Physics to at least 90 percent. If Thermo Electron achieves this 90-percent ownership threshold, it plans to acquire all remaining outstanding shares of Spectra-Physics common stock through a subsequent "short-form" merger, the timing of which will be announced at a later date. Shareholders who do not participate in the tender offer will also receive $17.50 in cash for their Spectra-Physics shares in the short-form merger. The tender offer and proposed subsequent short-form merger require Securities and Exchange Commission clearance of necessary filings. The short-form merger would not require Spectra-Physics board or shareholder approval.
