SIXTH REINSTATEMENT AND MODIFICATION OF THE
                 FOURTEENTH AMENDMENT AND FORBEARANCE AGREEMENT

         This Sixth Reinstatement and Modification of the Fourteenth Amendment
and Forbearance Agreement ("Agreement") is entered into as of May 3, 2003,
between Atchison Casting Corporation, a Kansas corporation (the "Borrower"),
Harris Trust and Savings Bank ("Harris"), as Agent (Harris in such capacity
being hereinafter referred to as the "Agent"), and each Bank currently party to
the Credit Agreement hereinafter identified and defined (the term "Bank Group"
as used herein to mean each Bank now and from time to time hereafter party to
the Credit Agreement and the Agent under the Credit Agreement for such Banks).


                                   BACKGROUND

          A. The Borrower, the Banks party thereto and the Agent entered into an
Amended and Restated Credit Agreement dated as of April 3, 1998 as the same has
been amended, waived, or otherwise modified prior to the date hereof by various
instruments and documents including without limitation that certain Fourteenth
Amendment and Forbearance Agreement dated as of October 17, 2002 (such Credit
Agreement, as the same has been amended, waived, or otherwise modified prior to
the date hereof, being referred to herein as the "Credit Agreement" and such
Fourteenth Amendment, as amended, modified, or reinstated prior to the date
hereof, being referred to herein as the "Fourteenth Amendment"). All capitalized
terms used herein without definition shall have the same meanings herein as such
terms have in the Fourteenth Amendment.

          B. On May 2, 2003, a Standstill Termination occurred due to the
Borrower's failure to pay in full all Obligations by the Termination Date of May
2, 2003 and the occurrence of such Standstill Termination rendered ineffective
the Fourteenth Amendment.

          C. The Borrower has requested that the Bank Group reinstate the
Fourteenth Amendment, extend the Termination Date (as defined in the Credit
Agreement) to May 31, 2003 and temporarily waive, or at least temporarily
forbear from enforcing its rights and remedies with respect to, the Existing
Defaults during the period (such period, as the same may be terminated earlier
pursuant to the terms hereof, being hereinafter referred to as the "Standstill
Period") ending on May 31, 2003 (the "Standstill Expiration Date"), on the terms
and conditions set forth in this Agreement.

         NOW, THEREFORE, upon the mutual promises contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, the Borrower and the Bank Group agree as follows:

          1. Reinstatement and Forbearance. Subject to the terms and conditions
of this Agreement, the Fourteenth Amendment is hereby reinstated and, unless and
until a Standstill Termination occurs after the date hereof:

               (a) credit shall remain available under and subject to the Credit
          Agreement as modified hereby to the Borrower; and

               (b) the Bank Group will not enforce collection of the Obligations
          or enforce its Liens on the Collateral or exercise any other right or
          remedy available under the Loan Documents or otherwise against the
          Borrower or any Subsidiary by virtue of (i) the Existing Defaults and
          (ii) continued noncompliance with the covenants therein referenced.

          2. Amendments. Upon the satisfaction of the conditions precedent to
effectiveness set forth in Paragraph 12 hereof, the Credit Agreement and the
Fourteenth Amendment are hereby amended as hereinafter set forth.

          3. Definition of "Termination Date". The definition of the term
"Termination Date" set forth in Section 4.1 of the Credit Agreement is hereby
amended and restated in its entirety to read as follows:

                  "Termination Date" means May 31, 2003.

          4. Schedule I to Fourteenth Amendment. Schedule I to the Fourteenth
Amendment shall be amended and restated in its entirety to read as set forth on
Annex A hereto.

          5. Canadian Steel Operating Budget. By no later than May 9, 2003, the
Borrower shall deliver to the Agent an operating budget for Canadian Steel
Foundries, Ltd. in form and substance reasonably acceptable to the Agent.

when due, and each Guarantor hereby confirms its guaranty of, all costs incurred
in the above referenced audits and appraisals.

          7. Loan Documents Remain Effective. Except as expressly set forth in
this Agreement, the Credit Documents remain unchanged and in full force and
effect. Without limiting the foregoing, the Borrower and its Subsidiaries shall

Default other than the Existing Defaults. The Borrower and each Guarantor hereby
acknowledges and confirms that: (i) the Obligations will continue to be secured
by Liens on all accounts, chattel paper, instruments, documents, general
intangibles, investment property, deposits, inventory, equipment and
substantially all other assets and properties of the Borrower and Guarantors'
pursuant to the mortgages, security agreements and other instruments and
documents heretofore executed and delivered by the Borrower and the Guarantors
to or for the benefit of the Bank Group; (ii) such mortgages, security
agreements and other instruments and documents, and the rights and remedies of
the Bank Group thereunder, the obligations of the Borrower and each Guarantor
thereunder, and the Liens created and provided for thereunder, in each case
remain in full force and effect and shall not be affected, impaired or
discharged hereby; and (iii) nothing herein contained shall in any manner affect
or impair the priority of the Liens and security interests created and provided
for thereby as to the obligations which would be secured thereby prior to giving
effect to this Agreement.

          9. Release. In consideration of the Required Banks' execution of this
Agreement and for other good and valuable consideration, receipt of which is
hereby acknowledged, (x) the Borrower and each Guarantor hereby acknowledges
that it has no defense, counterclaim, offset, cross-complaint, claim, or demand
of any kind or nature whatsoever that can be asserted to reduce or eliminate all
or any part of its liability to pay or perform any of the Obligations, or to pay
or perform any of its other obligations with respect to any other loans or other
extensions of credit or financial accommodations made available to or for its
account by any one or more members of the Bank Group, or to seek affirmative
relief or damages of any kind or nature from the Bank Group, and (y) the
Borrower and each Guarantor does hereby fully, unconditionally, and irrevocably
forever relieve, relinquish, release, waive, discharge, and hold harmless the
Bank Group and each of its members and each of its members' current and former

assigns of and from any and all claims, debts, actions, causes of action,
liabilities, demands, obligations, promises, acts, agreements, costs, expenses
(including but not limited to reasonable attorneys' fees) and damages of
whatsoever kind and nature, whether now known or unknown, based upon, resulting
from, arising out of, or in connection with loans or other extensions of credit
or financial

                                      -3-

accommodations made by any one or more members of the Bank Group from time to
time to or for the account of the Borrower or any Subsidiary, including, without
limitation, any Loans made under, and Letters of Credit issued under, the Credit
Agreement or in any way connected with or related to any other instrument or
document executed or delivered in connection therewith and/or the administration
or collection thereof and/or collateral therefor or guaranties thereof.

         10. No Waiver and Reservation of Rights. The Bank Group is not waiving
the Existing Defaults, but is simply agreeing to forbear from exercising its
rights with respect to the Existing Defaults to the extent expressly set forth
in this Agreement. The Bank Group is not obligated in any way to continue beyond
the Standstill Period to forbear from enforcing its rights or remedies, and the
Bank Group is entitled to act on the Existing Defaults after the occurrence of a
Standstill Termination as if such defaults had just occurred and the Standstill
Period had never existed. The Bank Group makes no representations as to what
actions, if any, the Bank Group will take after the Standstill Period or upon
the occurrence of any Standstill Termination, an Event of Default, or an event
which with notice or lapse of time, or both, would constitute an Event of
Default, and the Bank Group must and does hereby specifically reserve any and
all rights and remedies it has (after giving effect hereto) with respect to the
Existing Defaults and each other Event of Default that may occur.

          11. Integration. This Agreement is intended by the Bank Group as a
final expression of its agreement as to the subject matter hereof and is
intended as a complete and exclusive statement of the terms and conditions of
that agreement.

          12. Effectiveness. This Agreement shall take effect upon the
satisfaction of the following conditions:

               (a) the acceptance (without modification) by the Banks and the
          Borrower in the spaces provided for that purpose below;

               (b) the execution by the Guarantors of the acknowledgment
          attached hereto;

               (c) the Borrower shall have delivered to the Bank Group a weekly
          cash flow budget for the period from the date hereof through and
          including May 31, 2003 and the same shall be satisfactory to the
          Required Banks (it being understood that this is in addition to the
          Borrower's obligations pursuant to Paragraph 5 hereof); and

               (d) TIAA shall have reinstated its standstill agreement through
          May 31, 2003 in a manner reasonably acceptable to the Agent.

By its acceptance hereof, the Borrower and each Guarantor hereby represent that
they have duly considered the consequences of this Agreement after consultation
with counsel and such other advisors as each deems appropriate under the
circumstances, each has the necessary power and authority to execute, deliver,
and perform the undertakings contained herein, and that the same does bind each
of them hereto.


                                      -4-

         13. Submission to Jurisdiction; Waiver of Jury Trial. The Borrower and
each Guarantor hereby submits to the non-exclusive jurisdiction of the United
States District Court for the Northern District of Illinois and of any Illinois
State court sitting in the City of Chicago for purposes of all legal proceedings
arising out of or relating to this Agreement, the other Loan Documents or the
transactions contemplated hereby or thereby. The Borrower and each Guarantor
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of the venue of any such proceeding
brought in such a court and any claim that any such proceeding brought in such a
court has been brought in an inconvenient forum. THE BORROWER, EACH GUARANTOR,
THE AGENT, AND EACH BANK HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

         14. Miscellaneous. The Borrower shall pay all costs and expenses of the
Bank Group incurred in connection with the negotiation, preparation, execution,
and delivery of this Agreement and the administration of the Loan Documents and
the transactions contemplated thereby, including the reasonable fees and
expenses of counsel to the Bank Group. This Agreement shall be governed by and
construed in accordance with Illinois law (without regard to principles of
conflicts of laws).
