            On July 19, 1998, General Signal Corporation ("General Signal") and

Signal with and into SAC Corp., a Delaware corporation and wholly-owned 
subsidiary of SPX ("Sub").

            Under the terms of the proposed merger, 40% of the outstanding
shares of General Signal common stock, par value $6.67 per share issued through
1969, par value $1.00 per share issued subsequent to 1969 ("General Signal
Common Stock"), will be exchanged for cash and 60% of the outstanding shares of
General Signal Common Stock will be exchanged for shares of SPX common stock,
par value 10.00 per share ("SPX Common Stock"). Holders of shares of General
Signal Common Stock may elect to receive, in exchange for each of their shares,
either (i) $45 in cash, (ii) .6977 shares of SPX Common Stock or (iii) $18 in
cash and .4186 shares of SPX Common Stock, subject, in each case, to proration
mechanisms.

            The transaction is subject to, among other things, approval by both
companies' shareholders, normal governmental reviews and other customary
conditions. The proposed merger is intended to qualify as a tax-free
reorganization and to be accounted for on a reverse purchase basis.

            Following the merger, John B. Blystone will continue as Chairman,
President and CEO of SPX and two directors of General Signal will join the SPX
Board of Directors.

Agreement, dated as of February 1, 1996 (the "Rights Agreement"), by and between
General Signal and First Chicago Trust Company of New York, as Rights Agent,
with the effect of exempting the Merger, the Merger Agreement and the events and
the transactions contemplated thereby from the application of the Rights
