PRECISION CASTPARTS CORP. ANNOUNCES COMPLETION OF TENDER OFFER
FOR WYMAN-GORDON COMPANY COMMON STOCK

PORTLAND, Oregon, - November 25, 1999 - Precision Castparts Corp. (NYSE:PCP)
today announced that Precision Castpart's Corp.'s subsidiary, WGC Acquisition
Corp., has completed its tender offer for shares of common stock of Wyman-Gordon
Company (NYSE:WYG). Wyman-Gordon Company, headquartered in Grafton,
Massachusetts, is a leader in forgings, investment castings and composite
structures.

Precision Castparts Corp. (PCC) announced the proposed acquisition of
Wyman-Gordon Company on May 17, 1999, and commenced a cash tender offer on May
21, 1999, to purchase all outstanding shares of Wyman-Gordon Company common
stock for $20 per share. The acquisition of Wyman-Gordon Company was subject to
the tender of two-thirds of Wyman-Gordon Company's outstanding shares on a fully
diluted basis. At the expiration of the tender offer on November 24, 1999, 96
percent of Wyman-Gordon Company's outstanding shares on a fully diluted basis
had been tendered (99 percent of the total outstanding shares), and all tendered
shares have been accepted for payment. PCC expects to complete the acquisition
of the remaining 1 percent of the outstanding common stock of Wyman-Gordon
Company after approval of a merger between Wyman-Gordon Company and WGC
Acquisition Corp. by the Wyman-Gordon Company shareholders at a shareholders'
meeting expected to be held within 60 days.

PCC's acquisition of Wyman-Gordon creates a company that will be a key supplier
of both castings and forgings for aircraft engine components. In addition, the
acquisition will strengthen PCC's position in structural airframe, IGT, energy
and other industrial markets. Wyman-Gordon's casting business will become part
of a new Investment Cast Products segment, which will also include PCC
Structurals and PCC Airfoils, while Wyman-Gordon's forging business will
constitute its own segment, Forged Products. Mark Donegan, formerly president of
PCC Structurals, Inc., has been named president of Wyman-Gordon.

Precision Castparts Corp. is a worldwide manufacturer of complex metal
components and products. PCC is the market leader in manufacturing both large,
complex structural investment castings and airfoil castings used in jet aircraft
engines. In addition, PCC has expanded into the industrial gas turbine, fluid
management, industrial metalworking tools and machines, pulp and paper, advanced
metal forming technologies, tungsten carbide, and other metal products markets.
