SPX CORPORATION PRICES SENIOR NOTES

CHARLOTTE, NC – December 10, 2007 – SPX Corporation (NYSE:SPW) today announced the pricing of $500 million principal amount of its Senior Notes due 2014 to be sold to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non-U.S. persons in compliance with Regulation S under the Securities Act.

Subject to customary conditions, the offering is expected to close on December 13, 2007.

The notes will be unsecured senior obligations of the company guaranteed by each of the company’s domestic subsidiaries and future domestic subsidiaries that guarantee obligations under the company’s U.S. senior credit facilities and will pay interest at 7.625 percent per annum. The company may redeem the notes at any time prior to maturity at a price equal to 100 percent of the principal amount subject to a make-whole premium. Upon the occurrence of a change in control, holders of the notes will have the right to require the company to repurchase some of or all their notes.

The company intends to use the net proceeds from the sale of the notes for general corporate purposes, which may include the financing of the acquisition of APV, a division of Invensys PLC. Pending any such uses, the company intends to pay down outstanding amounts under various debt facilities and invest in cash and equivalents.
