PRESS RELEASE

        PIRATE CAPITAL LLC WINS SUPPORT FROM ISS IN PROXY CONTEST AGAINST
                                  GENCORP INC.

        ISS RECOMMENDS SHAREHOLDERS VOTE ON THE PIRATE CAPITAL LLC GREEN
          PROXY CARD AND FOR THE SHAREHOLDER PROPOSAL TO DECLASSIFY THE
                                      BOARD



NORWALK, CT, MARCH 22, 2006 PR Newswire/ -- Pirate Capital LLC today announced
that Institutional Shareholder Services (ISS), the nation's leading independent
proxy advisory firm, issued an analysis for the GenCorp Inc. (NYSE: GY) proxy
contest. ISS recommends that shareholders vote on the Pirate Capital GREEN proxy
card for Robert C. Woods and for the shareholder proposal to declassify the
board. ISS recommends that shareholders NOT vote on GenCorp's white proxy card.

ISS also commented on GenCorp's corporate governance, concluding that "the
company has not taken all necessary steps to ensure shareholder democracy." With
respect to Pirate Capital's proposal to declassify the board of directors, ISS
stated that "[t]he ability to elect directors is the single most important use
of the shareholder franchise, and all directors should be accountable on an
annual basis. A classified board can entrench management and effectively
preclude most takeover bids or proxy contests."

"We are pleased that ISS has recommended shareholders vote on the green proxy
card, and we urge shareholders to support all of our nominees as well as the
proposal to declassify the board," said Pirate Capital Portfolio Manager Carlton
B. Klein.

"I urge all shareholders to follow ISS' INDEPENDENT recommendation to VOTE THE
GREEN PROXY CARD. I also urge all shareholders to VOTE FOR TODD R. SNYDER,
ROBERT C. WOODS and DAVID A. LORBER," said Pirate Capital founder Thomas R.
Hudson Jr.

Pirate Capital beneficially owns 4,674,200 shares of GenCorp (8.4% of the
outstanding shares) and is GenCorp's second largest shareholder.

Shareholders that need assistance in voting their shares or have any questions
are invited to call D.F. King & Co., Inc. toll-free at (888) 887-0082.
