INTRODUCTORY STATEMENT

        SPX Corporation, a Delaware corporation (the "Company"), hereby amends and supplements its Tender Offer Statement on Schedule TO-I originally filed on January 6, 2006 as amended on January 25, 2006 ("Schedule TO-I") with respect to the offer by the Company to purchase the Liquid Yield Option™ Notes due February 6, 2021 (Zero Coupon-Senior) issued by the Company on February 6, 2001 (the "Securities"), upon the terms and subject to the conditions set forth in the Indenture (as defined below), the Company Notice, dated January 6, 2006, as amended January 25, 2006 (the "Company Notice"), the Securities and the related offer materials filed as Exhibits (a)(1)(B) to (d)(1) to this Schedule TO-I (which Company Notice and related offer materials, as amended or supplemented from time to time, collectively constitute the "Option"). The Securities were issued pursuant to an Indenture, dated as of February 6, 2001, between the Company and JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank, as Trustee (the "Trustee") (the "Indenture").

Item 4. Terms of the Transaction.

        Item 4 of the Schedule TO-I is hereby amended and supplemented by adding the following language:

        The holders' option to surrender the Securities for purchase expired at 5:00 p.m., New York City time, on February 6, 2006. The Company has been advised by the depositary, JPMorgan Chase Bank, N.A., that Securities with an aggregate principal amount at maturity of approximately $994,491,000 were validly tendered and have been purchased by the Company. The purchase price for the Securities was $663.86 per $1,000 in principal amount at maturity. Accordingly, the aggregate purchase price for all of the Securities validly tendered was $660,202,795.26. The Company paid the purchase price with cash on hand. This leaves $201,000 in aggregate principal amount at maturity of Securities outstanding or 0.02% of the Securities outstanding.

        On February 7, 2006, the Company issued the press release announcing the results of the offer, a copy of which is attached hereto as Exhibit (a)(5)(B) and incorporated herein by reference.
