and Chief Executive Officer of SPX Corporation (the "Company") solely for

Item 1.01 Entry into a Material Definitive Agreement.
- ----------------------------------------------------

On December 8, 2004, John B. Blystone resigned and retired as the Chairman,
President and Chief Executive Officer of SPX Corporation. Mr. Blystone also
resigned as a Director of the Company. A copy of the press release
announcing Mr. Blystone's retirement and resignation is attached hereto as
Exhibit 99.1 and is incorporated herein by reference.

In connection with Mr. Blystone's retirement and resignation, on December
8, 2004, the Company and Mr. Blystone entered into a separation agreement
(the "Separation Agreement"). Pursuant to the Separation Agreement, Mr.
Blystone retired and resigned, his employment agreement with the Company
was terminated and he forfeited all of the 1,000,000 share special
retention restricted stock grant issued in 2002. The Separation Agreement
also provides that Mr. Blystone will receive (i) a lump-sum payment of $2.8
million which is equal to two (2) times his base salary; (ii) an amount
equal to Mr. Blystone's bonus bank balance remaining after calculations for
the 2004 plan year are completed under the SPX Corporation EVA Incentive
Compensation Plan; (iii) a lump-sum payment of life insurance premiums,
estimated at $387,000; (iv) continuation for three (3) years of health and
welfare benefits, estimated at $14,200 per annum based upon 2004 amounts;
and (v) a lump-sum payment of $136,600 for unused vacation pay. As of
December 8, 2004, Mr. Blystone held options for 6,253,972 shares of common
stock ranging in exercise prices of $30 to $150 of which options for
4,053,973 shares were vested. As part of the Separation Agreement, the
options for the remaining 2,199,999 shares became vested. Mr. Blystone will
have until the earlier of the expiration of the options or two (2) years
from the date of his retirement and resignation to exercise all of these
options. Mr. Blystone was vested in 33,333 shares of a restricted stock
grant made in 2004, which would have vested in January 2005, and forfeited
the remaining 66,667 shares of such 100,000 share grant. Mr. Blystone will
be obligated to repay the full outstanding balance of his home relocation
loan of $2.5 million within 150 days, the period provided for in the
original loan.

Mr. Blystone will also receive a single annuity at age 55 for an amount
equal to $8,000,000, which he can take as a lump sum or in installments.
Mr. Blystone is obligated to comply with (i) certain non-competition
provisions until December 8, 2006 and (ii) confidentiality and cooperation
requirements for an indefinite period.

Mr. Blystone is entitled to previously earned pension benefits under the
Company's qualified pension plan, supplemental pension plan and
Supplemental Retirement Plan for officers, as described in the Company's
prior proxy statements. These benefits will be paid, at Mr. Blystone's
election, either annually ($1,860,000 per year if Mr. Blystone elects to
receive payments starting at age 55) or in a lump sum payment.

A copy of the Separation Agreement is attached hereto as Exhibit 10.1 and
is incorporated herein by reference.
