The offer is subject to the satisfaction of certain conditions, including the closing of the sale of SPX Corporation's Edwards Systems Technology business (the "Edwards closing") and receipt of consents in respect of the requisite principal amount of Notes. The offer is being extended because the Edwards closing has not yet occurred. As of 5:00 p.m., New York City time on March 14, 2005, approximately 63.92% of the 61/4% Senior Notes and approximately 79.25% of the 7 1/2% Senior Notes had tendered into the offer, which would represent receipt of the requisite consents for each of the 6 1/4% Senior Notes and the 7 1/2% Senior Notes, upon the closing of the offer. SPX is extending each of the tender offers for the 7 1/2% Senior Notes and the 6 1/4% Senior Notes to 5:00 p.m., New York City time on March 18, 2005. In addition, the date by which holders of Notes needed to tender their Notes in order to obtain the consent payment has also been extended to March 18, 2005. Accordingly, holders who tender their Notes at or prior to 5:00 p.m., New York City time, on March 18, 2005 will receive the total consideration, including the consent payment, based on the applicable fixed spread set forth in the Supplement dated February 18, 2005 (the "Supplement") to the Offer to Purchase and Consent Solicitation Statement dated February 4, 2005 (the "Offer to Purchase"), subject to the terms and conditions set forth in the Offer to Purchase. In addition, the price determination date has now been extended to 2:00 p.m., New York City time on March 16, 2005. The terms of the tender for the 6 1/4% Senior Notes and the 7 1/2% Senior Notes remain unchanged. As described above, the consent solicitations and the tender offers will expire at 5:00 p.m., New York City time, on March 18, 2005, unless extended. The consent solicitations and tender offers were earlier scheduled to expire at 5:00 p.m., New York City time, on March 17, 2005. Holders who tender their Notes pursuant to the offers will be required to consent to the proposed amendments. The purpose of the consent solicitations is to, among other things, eliminate substantially all of the restrictive covenants and certain of the default provisions contained in the indenture governing the Notes.
