OF TENDER OFFER FOR WYMAN-GORDON COMPANY COMMON STOCK

PORTLAND, Oregon and GRAFTON, Massachusetts - October 1, 1999 - Precision
Castparts Corp. (NYSE: PCP) and Wyman-Gordon Company (NYSE: WYG) today announced
that the expiration date of the previously announced $20.00 per share cash
tender offer by Precision Castparts Corp.'s subsidiary, WGC Acquisition Corp.,
for all outstanding shares of common stock of Wyman-Gordon Company has been
extended until midnight, New York City time, on Monday, November 1, 1999;
provided, however, that if Precision Castparts Corp., Wyman-Gordon Company and
the Federal Trade Commission (FTC) reach agreement on the terms of the proposed
consent order discussed below prior to October 18, 1999, the expiration date of
the tender offer will be the date which is ten business days immediately
following the public record date of such agreement.

As previously announced, the FTC staff has indicated to Precision Castparts
Corp. that it will recommend to the FTC that the proposed acquisition be
permitted to proceed if Precision Castparts Corp. and Wyman-Gordon Company
agree to a consent order pursuant to which Precision Castparts Corp. and
Wyman-Gordon Company would divest certain Wyman-Gordon Company investment
casting operations and reach agreement with one or more buyers to sell a portion
of the assets to be divested prior to Precision Castparts Corp.'s acquisition of
Wyman-Gordon Company. Precision Castparts Corp. and Wyman-Gordon Company are
making good progress in their efforts to sell the assets that are required to be
divested. Precision Castparts Corp. and Wyman-Gordon Company are also continuing
to negotiate the terms of an agreement with the FTC with respect to the assets
to be divested. There can be no assurance that Precision Castparts Corp. and
Wyman-Gordon Company will reach final agreement with a buyer for the assets the
FTC staff has requested to be divested or that the FTC will find the potential
buyer or buyers suitable.

As of September 29, 1999, approximately 22,902,000 shares of common stock of
Wyman-Gordon Company had been tendered in the tender offer. This constitutes
approximately 64.1% of Wyman-Gordon Company's outstanding shares as of the
commencement of the tender offer.

Precision Castparts Corp. is a worldwide manufacturer of complex metal
components and products. Wyman-Gordon Company is a leader in forgings,
investment castings and composite structures.
