         WHEREAS, the Obligors, the Lenders, the Bank Agent and the Collateral

hereby acknowledged, the Borrower, TIAA, the Collateral Agent and each of the
Banks agree as follows:

SECTION 1.           AMENDMENTS.

         Subject to the terms and conditions of this Amendment, the Cash
Agreement is hereby amended as follows:

                   (a) The fourth sentence of Section 4.1 of the Cash Agreement
         is hereby amended in its entirety to read as follows:

                  "In addition, the Collateral Agent shall be free in its sole
                  discretion to elect not to transfer money to the Disbursement
                  Accounts:

                           (i) for any proposed item that is not reflected in
                  the Operating Period Budget;

                           (ii) if on a monthly basis an actual itemized
                  individual expense or category of expenditure exceeds that set
                  forth in the Operating Period Budget by: (A) 25%, in the case
                  of expenditures for a given week and (B) 10%, in the case of
                  expenditures for a given month and (C) $500,000 for aggregate
                  expenditures during the forecast period from December 1, 2002
                  through April 3, 2003; or

                           (iii) upon the occurrence of the Forbearance End
                  Date.

                  For purposes of the foregoing clause (ii), La Grange Foundry
                  Inc., Canadian Steel Foundries, Ltd., Empire Steel Castings,
                  Inc. and PrimeCast, Inc. shall be excluded from the variance
                  calculations."

SECTION 2. CONDITIONS OF EFFECTIVENESS.

         This Amendment shall become effective when and only when the Collateral
Agent shall have received counterparts of this Amendment executed by the
Obligors and the Requisite Lenders.

SECTION 3.           EXPENSES.

         The Borrower agrees to pay on demand all costs and expenses of the
Lenders, the Bank Agent and the Collateral Agent incurred in connection with the
negotiation, preparation, execution, and delivery of this Amendment and the
administration of the Cash Agreement (as amended hereby) and the transactions
contemplated by the Cash Agreement (as amended hereby), including the reasonable
fees and expenses of counsel to the Lenders, the Bank Agent and the Collateral
Agent.

SECTION 4.           CASH AGREEMENT REMAINS EFFECTIVE.

         Except as expressly set forth in this Amendment, the Cash Agreement
remains unchanged and in full force and effect. Without limiting the foregoing,
the Obligors shall comply with all of the terms, conditions, and provisions of
the Cash Agreement (as modified hereby) except to the extent such compliance is
irreconcilably inconsistent with the express provisions of this

                                      -2-

Amendment. All references in the Cash Agreement to the term "Forbearance End
Date" shall mean the Forbearance End Date as defined herein.

SECTION 5.           INTEGRATION.

         This Amendment is intended by the parties which are signatories hereto
as a final expression of their agreement as to the subject matter hereof and is
intended as a complete and exclusive statement of the terms and conditions of
that agreement.

SECTION 6.           COUNTERPARTS.

         This Amendment may be executed in any number of counterparts, each
which shall be deemed an original, but all of which together shall constitute
but one instrument.

SECTION 7.           GOVERNING LAW.

         This Amendment shall be deemed to be executed and has been delivered
and accepted in Chicago, Illinois by signing and delivering it there. Any
dispute between the parties hereto arising out of, connected with, related to,
or incidental to this Amendment, and whether arising in contract, tort, equity,
or otherwise shall be resolved in accordance with the internal laws and not the
conflicts of law provisions of the State of Illinois.

                           [NO FURTHER TEXT THIS PAGE]
