                                  GenCorp Inc.
         Unaudited Pro Forma Combined Consolidated Financial Statements

The following unaudited pro forma combined consolidated financial statements
have been prepared to reflect the sale of Aerojet's EIS business unit and the
previously disclosed December 2000 acquisition of The Laird Group's Draftex
International Car Body Seals Division (Draftex). The unaudited pro forma
combined consolidated statements of operations have been prepared as if both of
these transactions occurred on December 1, 1999, while the unaudited pro forma
combined consolidated balance sheet has been prepared as if both of these
transactions occurred on August 31, 2001.

The Draftex acquisition was accounted for under the "purchase method". Under
this method of accounting, the assets acquired and liabilities assumed were
recorded at estimated fair values. A final allocation is expected to be made in
late 2001 after negotiations with the seller as to any purchase price
adjustments have been completed. The final valuation of the assets acquired and
liabilities assumed in connection with the acquisition may differ significantly
from the estimates reflected in the pro forma financial statements.

The unaudited pro forma financial statements and other data have been prepared
based on preliminary estimates, available information and the assumptions
described in the notes thereto and may be revised as additional information
becomes available. The unaudited pro forma combined consolidated financial
statements should be read in conjunction with the Draftex combined consolidated
consolidated financial statements and notes thereto, and GenCorp's historical
consolidated financial statements included in its Annual Report on Form 10-K and
Quarterly Reports on Form 10-Q as filed with the Securities and Exchange
Commission. The following unaudited pro forma financial statements and other
data do not purport to be indicative of the financial position or results of
operations that would have been reported had the transactions been effected on
the dates indicated, or which may be reported in the future. The unaudited pro
forma financial information does not give effect to anticipated cost savings or
incremental costs that may occur as a result of restructuring, integration and
consolidation of the Draftex operations.

              The accompanying notes are an integral part of these
                        pro forma financial statements.





                                     GENCORP
     NOTES TO UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS


PRO FORMA ADJUSTMENTS - The following adjustments have been made to the
unaudited pro forma combined consolidated financial statements:

     (a)  Amortization of estimated purchased intangible assets of $60 million
          assuming the Draftex acquisition had taken place at the beginning of
          the periods presented. Purchased intangible assets are being amortized
          using the straight-line method over a useful life of 20 years.

     (b)  Reduction in amortization of debt origination fees associated with
          GenCorp's existing senior credit facilities. This reduction assumes
          that if both the EIS sale and the Draftex acquisition had occurred as
          of the beginning of the periods presented, a new senior credit
          facility would not have been needed (the net proceeds from the
          EIS sale exceeded the cash cost of Draftex) and related debt
          origination fees would not have been incurred. No reduction of
          amortization of debt origination fees is required for the year ended
          November 30, 2000 since the new senior credit facilities agreement
          was entered into on December 28, 2000.

     (c)  Reduction of interest expense assuming that the net proceeds from the
          sale of EIS were applied to debt outstanding at the beginning of the
          periods presented. The average interest rate on debt outstanding at
          the beginning of periods presented was 8.0% for the year ended
          November 30, 2000 and 7.25% for the nine months ended August 31, 2001.
          The effect of this pro forma adjustment is partially offset during the
          year ended November 30, 2000 by an increase in interest expense for
          debt incurred relating to the purchase of Draftex assuming this
          transaction had occurred at the beginning of the periods presented.

     (d)  Adjustment for allocations of interest and management fees from Laird
          which are included in the historical financial statements of Draftex
          for the year ended December 31, 2000. These allocations were based on
          the intercompany balances that each company within the division had
          with Laird. These management fees primarily related to salaries and
          related costs of executive management and their support staff,
          including the legal, human resources, finance, and other
          administrative functions. No such amounts are included in the
          historical Draftex financial statements for the nine months periods
          ended August 31, 2001 presented herein, and therefore, no pro forma
          adjustment is required for this period.

     (e)  Adjustment related to foreign currency option and forward contracts
          entered into in connection with the Draftex acquisition. The purchase
          and settlement of these foreign currency contracts resulted in GenCorp
          recognizing a loss of $8 million during the year ended November 30,
          2000 and a gain of $11 million during the nine months ended August 31,
          2001.

     (f)  Income tax effect of pro forma adjustments computed using GenCorp's
          effective income tax rate of 40% for the year ended November 30, 2000
          and 39% for the nine months ended August 31, 2001.



     (g)  Aerojet currently has an agreement with the U.S. government under
          which the government recognizes as allowable for government contract
          cost purposes 88% of Aerojet's environmental costs relating to
          operations including EIS. The remaining 12% of these costs must be
          borne by Aerojet. Adjustments assume a $40 million escrow payment
          would have been made on August 31, 2001 which reduces reserves for
          environmental remediation costs and provides for recovery of 88% of
          this amount through existing government contracts.

     (h)  Income tax effect assuming the sale of EIS at August 31, 2001 for
          gross proceeds of $315 million and resulting in an after-tax gain of
          $124 million.

     (i)  Application of gross proceeds of $315 million from the sale of EIS,
          less the $40 million escrow payment described in (g) above, to debt
          outstanding at August 31, 2001.

     (j)  Recognition of a gain from the EIS, net of tax assuming the
          transaction occurred at August 31, 2001.

     (k)  Adjustment to retain the historical earnings and profits of EIS
          through August 31, 2001, assuming the sale of EIS occurred at August
          31, 2001.

     (l)  Draftex's fiscal year ends on December 31 each year. Accordingly, the
          historical statements of operations for the year ended November 30,
          2001 include the results of operations for Draftex for the period
          January 1, 2000 through December 29, 2000. The GenCorp historical
          statements of operations for the nine months ended August 31, 2001
          include the results of operations for Draftex for eight months in this
          period because of the December 29, 2000 acquisition date. Accordingly,
          the Draftex historical statement of operations for this period
          represents the results of operations for one month.
