Shares held in the GenCorp Retirement Savings Plan Trust (Plan Trust) have been updated with 65.8961 shares as of January 29, 2007 to reflect the value in the participant's account as per the Plan Administrator's records. The number of shares reported is calculated by dividing the dollar value of the participant's account by the closing market price of the stock on the day reported above. This calculation yields only the approximate number of shares in the participant's account because the cash component in the Plan Trust (target 2%) is allocated to each participant's account on a pro rata basis, and the cash component varies based on overall activity of all participants in the Plan Trust.
