INDEPENDENT AUDITORS' REPORT


To the Plan Administrator and Participants
  Jahn Foundry Corp. Union 401(k) Plan

We have audited the accompanying statements of net assets available for benefits
of the Jahn Foundry Corp. Union 401(k) Plan (the "Plan") as of December 31, 2000
and 1999, and the related statements of changes in net assets available for
benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatements. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits as of December 31, 2000 and
1999, and the changes in net assets available for benefits for the years then
ended in conformity with accounting principles generally accepted in the United
States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules listed in the
Table of Contents are presented for the purpose of additional analysis and are
not a required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under Employee Retirement Income Security Act of 1974.
These schedules are the responsibility of the Plan's management. Such schedules
have been subjected to the auditing procedures applied in the audit of the basic
2000 financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

JAHN FOUNDRY CORP. UNION 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2000 AND 1999
- -------------------------------------------------------------------------------


1.   DESCRIPTION OF THE PLAN

     The following description of the Jahn Foundry Corp. Union 401(k) Plan (the
     "Plan") provides only general information. Participants should refer to the
     Plan agreement for a more complete description of the Plan's provisions.

     General - The Plan is a defined contribution plan sponsored by Jahn Foundry
     Corporation (the "Company" or the "Plan Sponsor") a subsidiary of Atchison
     Casting Corporation. Automatic Data Processing, Inc. ("ADP") served as the
     custodian of the Plan through July 5, 2000 at which time Prudential
     Investments ("Prudential") became the custodian of the Plan. The Plan is
     subject to the provisions of the Employee Retirement Income Security Act of
     1974 ("ERISA").

     During 2000, the Plan transferred $5,148 to the Atchison Casting
     Corporation 401(k) Plan (the "Corporation Plan"), which represents the
     account balances of collectively bargained employees who became salaried
     employees and were subsequently transferred to the Corporation Plan.

     Eligibility and Participation - Union employees are eligible for
     participation in the Plan after completing at least three months of
     continuous service, providing they meet the prescribed eligibility
     requirements set forth in the Plan document.

     Contributions - Plan participants may contribute up to 15% of their salary
     on a pre-tax basis, subject to certain Internal Revenue Code ("IRC")
     limitations.

     Participant Accounts - Each participant's account is credited with the
     participant's contributions and withdrawals, as applicable, and Plan
     earnings. The benefit to which a participant is entitled is the benefit
     that can be provided from the participant's account.

     Vesting - Participants are immediately vested in their contributions plus
     actual earnings thereon.

     Investment Options - Upon enrollment in the Plan, a participant may direct
     contributions in the following investment options.

     The funds offered by Prudential as of December 31, 2000 were as follows:

     For more information regarding the Plan's investment alternatives and fund

     information provided by such funds.

     Participants may change investment elections for future contributions at
     any time and may transfer any existing balances among the offered funds,
     subject to exchange limitations imposed by the funds.

     Payment of Benefits - Upon termination of service due to death, layoff,
     disability, hardship, termination or retirement, a participant may elect to
     receive either a lump sum amount equal to the value of the vested interest
     in his or her account or annual installments. If a participant dies, the
     balance in his or her account becomes fully vested and payable to the
     beneficiary.

     Expenses - Expenses of the Plan are paid by either the Plan or the Plan
     Sponsor, as provided by the Plan agreement.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Accounting - The financial statements of the Plan are prepared
     under the accrual basis of accounting.

     Use of Estimates - The preparation of financial statements in conformity
     with accounting principles generally accepted in the United States of
     America requires management to make estimates and assumptions that affect
     the reported amounts of assets, liabilities and changes therein, and
     disclosure of contingent assets and liabilities. Actual results could
     differ from those estimates.

     Investments Valuation and Income Recognition - The December 31, 2000
     investments, excluding the guaranteed interest contract, are stated at fair
     values as determined by quoted market prices. See Note 3 regarding the
     valuation of guaranteed interest contracts. The December 31, 1999
     investments, excluding the common/collective trust, were stated at fair
     values as determined by quoted market prices. The

                                       5


     common/collective trust fund was estimated at fair value, which was
     determined based on the underlying values of the funds.

     Purchases and sales of securities are recorded on a trade-date basis.
     Interest income is recorded on the accrual basis. Dividends are recorded on
     the ex-dividend date.

     Payment of Benefits - Benefits are recorded when paid.

3.   INVESTMENT CONTRACT WITH INSURANCE COMPANY

     The Plan has applied the provisions of Statement of Position ("SOP") 94-4,
     "Reporting of Investment Contracts Held by Health and Welfare Benefit Plans
     and Defined Contribution Pension Plans." SOP 94-4 requires a defined
     contribution plan to report investment contracts at fair value unless such
     contract is fully benefit responsive. The Prudential contract for this Plan
     has been deemed to be fully benefit responsive, according to provisions of
     SOP 94-4. As such, the contracts are presented at contract value which
     approximates fair value, on the statement of net assets available for
     benefits as of December 31, 2000. The crediting interest rates for the year
     ended December 31, 2000 for the contract ranges from 4.85% -5.90%. The
     crediting interest rate is reset upon the maturity of the contract.

4.   INVESTMENTS

     The Plan's investments which exceeded 5% of net assets available for
     benefits as of December 31, 2000 and 1999 are as follows:



                                                                                  2000             1999

6.   RELATED PARTIES

     Certain Plan investments are shares of mutual funds and a guaranteed
     interest contract managed by Prudential. Prudential is the custodian as
     defined by the Plan from July 5, 2000 through December 31, 2000 and,
     therefore, these transactions qualify as party-in-interest.

     Certain Plan investments held during 1999 and 2000 were shares of mutual
     funds and common/collective trusts held by ADP. ADP was the custodian as
     defined by the Plan through July 5, 2000, therefore, these transactions
     qualify as party-in-interest.

7.   PLAN TERMINATION

     Although it has not expressed any intention to do so, the Company has the
     right under the Plan to discontinue its contributions at any time and to
     terminate the Plan subject to the provisions of ERISA.

8.   TAX STATUS

     The non-standardized prototype plan document adopted by the Plan has
     received a favorable opinion letter from the Internal Revenue Service
     stating that the Plan and related trust are designed in accordance with the
     Internal Revenue Code ("IRC"). However, a determination letter has not been
     requested for the Plan's specific adoption agreement. The Plan Sponsor
     believes that the Plan, as adopted, is designed and is currently being
     operated in compliance with the applicable requirements of the IRC.
