       SPX CORPORATION ANNOUNCES EXTENSION OF ITS CASH TENDER OFFERS
   FOR ITS 6 1/4% SENIOR NOTES DUE 2011 AND 7 1/2% SENIOR NOTES DUE 2013

     CHARLOTTE, NC - March 15, 2005 - SPX Corporation (NYSE: SPW), today
announced that it is extending its pending tender offers for its 7 1/2%
Senior Notes due 2013 (the "7 1/2% Senior Notes") and for its 6 1/4% Senior
Notes due 2011 (the "6 1/4% Senior Notes") (collectively the "Notes"). 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.

     J.P. Morgan Securities Inc. is the Lead Dealer Manager for the offers
and Lead Solicitation Agent for the consent solicitations and can be
