                      AEROJET AND PRATT & WHITNEY ANNOUNCE
                      ------------------------------------
                   INTENT TO FORM NEW SPACE PROPULSION COMPANY
                   -------------------------------------------

         SACRAMENTO, CALIFORNIA, JULY 17, 2000 - Aerojet-General Corp., the
aerospace and defense segment of GenCorp Inc. (NYSE: GY), and Pratt & Whitney
(P&W), a unit of United Technologies Corp. (NYSE: UTX), announced today their
intention to form a new space propulsion company. Aerojet and P&W Space
Propulsion (SP) have signed a letter of intent, subject to execution of a
definitive agreement and government agreements and approvals. A definitive
agreement is expected to be complete before the end of the calendar year.

         Under the agreement currently being negotiated, Pratt & Whitney would
have the majority interest in the new company, which would operate out of P&W
facilities. P&W SP currently has facilities in California, Alabama and Florida.
Most of Aerojet's propulsion programs would be acquired by the new company in
exchange for cash and a 20 percent equity interest in the new company. Aerojet's
propulsion business, located in Sacramento, accounted for approximately
one-third of its 1999 revenues of $615 million.

         "This proposed transaction is in accordance with our stated intent to
explore all possible alternatives to enhance shareholder value. We have
maintained that the propulsion industry needs to consolidate in order to reduce
costs and become more efficient. This has been an important strategic priority
for our corporation," said Bob Wolfe, Chairman and CEO of GenCorp. "This
transaction, if completed, would enable us to focus in other defense industries,
including space electronics. With the relocation of a number of propulsion
operations from Sacramento, we will accelerate utilization of the valuable
property assets we have in Sacramento, which offer tremendous potential to
contribute significantly to the economy of the region," Wolfe added.

         "Aerojet and Pratt & Whitney make an excellent fit, both experts in the
propulsion industry. The new company would combine the distinctive products,
capabilities and technologies of each to provide significant improvements to
customers," said Carl Fischer, President of Aerojet.

         If the agreement is completed, Aerojet would continue to operate some
propulsion programs in Sacramento that would not be acquired by the new company,
and would complete the environmental remediation of the Sacramento site. The
final agreement is contingent on continuation of Aerojet's existing agreement
with the U.S. Government concerning the allowability of environmental
remediation costs at its Sacramento facility.

         The transaction would not affect GenCorp's rapidly growing Aerojet Fine
Chemicals business.

industry. In addition to missile and space propulsion systems, Aerojet serves
the space electronics, and smart munitions and armaments segments of the
aerospace and defense industry. Aerojet has about 3,000 employees. There are

propulsion business.

         P&W SP builds propulsion systems for liquid rockets and hypersonic
propulsion systems in West Palm Beach, Fla. and solid rocket propulsion systems
in San Jose, Calif. P&W SP employs about 1,300 people. P&W is a unit of United
Technologies Corporation, located in Hartford, Conn.
