do all or any of the following:

     1.     To execute and file with the Securities and

     None of Kevin L. Lilly, Spencer Conard, Brian Webb or

acting or refraining from acting under this power, except for
such attorney's own willful misconduct or gross negligence.
The undersigned acknowledges that the foregoing attorneys-in-
fact, in serving in such capacity at the request of the
undersigned, are not assuming, nor is SPX Corporation assuming,

     This Power of Attorney is governed by Delaware law.

     This Power of Attorney shall remain in full force and

the undersigned of a written notice of revocation of this Power
of Attorney.  The undersigned shall have the right to revoke
this Power of Attorney at any time.
