         WHEREAS,  the LIFO Agent and the LIFO  Banks are  willing to enter into
the LIFO Credit Agreement with Amcast only on certain terms and conditions,  one

         WHEREAS,  Amcast,  Bank  One  and the  CTC  Agent  deem it to be in the

and the CTC Banks for the LIFO Banks to provide  loans and other  extensions  of
credit to Amcast pursuant to the LIFO Credit Agreement;

         NOW, THEREFORE,  in consideration of the foregoing,  the parties hereto
agree as follows:

     SECTION 1.  Definitions.  As used in this  Agreement,  the following  terms
          shall have the following meanings:

                  "CTC Cash  Collateral"  shall mean One Million Fifty  Thousand
         Dollars  ($1,050,000),  which amount shall be pledged by Amcast to Bank
         One to secure  the  obligations  of Amcast to Bank One under the Amcast
         Guaranty, and held in the CTC Cash Collateral Account.

                  "CTC Cash  Collateral  Account"  shall mean a deposit  account
         opened by Amcast for the benefit of Bank One and located at Bank One.

         Security Documents, as defined in the CTC Credit Agreement,  the Amcast
         Guaranty,  and the other documents,  instruments or agreements executed
         in  connection  with  the  foregoing,  as  amended  and  as  any of the
         foregoing  may  from  time to  time be  further  amended,  restated  or
         otherwise modified or replaced.

                  "CTC Default"  shall mean any Default or Event of Default,  as
         defined  in the CTC  Credit  Agreement,  that  may now  exist  or shall
         hereafter occur, including, but not limited to, any Default or Event of
         Default that shall exist as a result of the Amcast Guaranty Defaults.


<PAGE>

                  "CTC  Refinancing  Event of  Default"  shall mean any Event of
         Default,  as defined  in the CTC Credit  Agreement  to be  executed  in
         connection  with the  refinancing  described in Section 6 hereof,  that
         shall occur subsequent to the date of such refinancing.

                  "Subordination Agreement" shall mean the Subordination, Waiver
         and  Consent  Agreement,  dated as of the date  hereof,  among  various
         creditors of Amcast, as specified therein.

         SECTION 2. Forbearance. The CTC Agent and the CTC Banks hereby agree to
forbear  from  exercising  any of the rights or  remedies  available  to the CTC
Agent,  the CTC Banks or Bank One under the Amcast  Guaranty  as a result of the
occurrence  or  existence  of any CTC  Default for the period from March 4, 2001
through  the latest of (a) April 15,  2002,  (b) the last day of the  Commitment
Period,  as  defined  in  the  LIFO  Credit  Agreement,  (c)  the  date  of  the
acceleration of the indebtedness  under the Existing Credit Agreement or (d) the
date of the  irrevocable  payment  in full of all  indebtedness  under  the LIFO
Credit  Agreement and  termination  of all  commitments  thereunder  (whether at
maturity, by acceleration or otherwise) (the "Forbearance Period").

         SECTION 3. Waiver of Certain Defaults. In addition to the agreements of
CTC Agent and the CTC Banks set forth in Section 2 hereof,  effective  as of the
date  hereof,  CTC Agent  and the CTC Banks  hereby  waive the  Amcast  Guaranty
Defaults.

         SECTION 4. Rescission of Acceleration  Notice.  CTC Agent, on behalf of
the CTC Banks,  hereby rescinds the Acceleration  Notice with respect to Amcast.
Effective as of the date hereof,  no amounts  shall be due from Amcast under the
Amcast  Guaranty.  The  foregoing  shall  in no  way  affect  or  apply  to  the
Acceleration  Notice  as it  applies  to CTC  and  the  indebtedness  and  other
obligations under the CTC Credit Agreement shall continue to be due and payable.

         SECTION 5. CTC Cash Collateral. Concurrently with the execution of this
Agreement, Amcast shall deliver the CTC Cash Collateral to Bank One and the same
shall be deposited in the CTC Cash Collateral  Account.  The CTC Cash Collateral
and the CTC Cash Collateral Account shall be subject to an Assignment of Deposit
Account Agreement  consistent with the terms of this Agreement.  Notwithstanding
anything  in any CTC  Document to the  contrary,  Bank One shall not enforce its
rights with respect to, or otherwise  apply,  in whole or in part,  the CTC Cash
Collateral  during the  Forbearance  Period  unless a CTC  Refinancing  Event of
Default shall have occurred and be  continuing.  If a CTC  Refinancing  Event of
Default  shall occur  during the  Forbearance  Period that  results from (a) the
failure  of CTC  to  make a  scheduled  payment  of  principal  (assuming  equal
principal  payments)  or interest  when due under the note or notes  executed in
connection  with the  refinancing  (as  described  in  Section 6 hereof)  of the
indebtedness  that exists  under the CTC Credit  Agreement or (b) a violation of
the  insolvency/bankruptcy  event of default  provision,  then Bank One shall be
entitled  to  immediately  enforce  its  rights  with  respect  to the CTC  Cash
Collateral.  However,  if a CTC Refinancing  Event of Default shall occur during
the Forbearance Period for any reason not referenced in the foregoing  sentence,
then Bank One shall only be entitled  to enforce its rights with  respect to the
CTC Cash Collateral upon thirty (30) days' prior written notice to CTC,  Amcast,
Existing Agent and LIFO Agent.  Upon the expiration of the  Forbearance  Period,
Bank One shall be permitted to apply all or part of the CTC Cash  Collateral  to
the payment of any indebtedness due and owing under the Amcast Guaranty.


<PAGE>

         SECTION  6.  Authorization;   CTC  Documents.   The  CTC  Agent  hereby
represents  and  warrants  to the other  parties  hereto  that that CTC Agent is
authorized  to execute and deliver  this  Agreement  on behalf of the CTC Banks.
Except as herein  otherwise  specifically  provided,  all  provisions of the CTC
Documents  shall remain in full force and effect and be  unaffected  hereby.  In
addition,  the parties hereto  acknowledge  that the CTC Agent and the CTC Banks
intend  to  refinance  or  restructure  the  indebtedness  evidenced  by the CTC
Documents.  The parties hereto agree that the provisions of this Agreement shall
apply to any such refinancing or  restructuring,  including any facility of Bank
One or any of its  affiliates  and  whether  or not  such  facility  shall be an
agented  credit  facility.  The parties  further  agree that the loan  documents
prepared by Bank One or CTC Agent in connection  with the aforesaid  refinancing
shall be drafted  such that no CTC Default or CTC  Refinancing  Event of Default
shall exist on the Closing Date of such refinancing.

         SECTION 7. No Waiver of Rights.  No waiver shall be deemed to have been
made by any party hereunder of any of its rights hereunder unless the same shall
be in writing signed on behalf of such party; provided that the LIFO Agent shall
have the right to act on behalf of the LIFO Banks in  accordance  with the terms
of the LIFO Credit  Agreement.  Each waiver, if any, shall be a waiver only with
respect to the specific  instance involved and shall in no way impair the rights
of any party.

         SECTION 8. Successors and Assigns.  This Agreement shall be immediately
binding upon Amcast,  the LIFO Agent,  the LIFO Banks,  CTC Agent, the CTC Banks
and Bank One, and their  respective  successors  and assigns,  and shall benefit
each of the  Creditors,  as defined in the  Subordination  Agreement,  and their
respective successors and assigns,  whether any such person or entity shall be a
party hereto.

     SECTION 9. Governing Law. This  Agreement  shall be construed  according to
          the laws of the  State  of  Ohio,  without  regard  to
          principles of conflicts of laws.

         SECTION 10.  Entire  Agreement.  This  Agreement  sets forth the entire
agreement and  understanding  among the parties as to the subject  matter hereof
and merges and supersedes all prior discussions, agreements, and undertakings of
every kind and nature among them with respect to the subject matter hereof.

         SECTION 11. Counterparts.  This Agreement may be executed in any number
of counterparts,  and by the parties hereto on the same or separate counterparts
and by  facsimile  signature,  and each  such  counterpart,  when  executed  and
delivered,  shall be deemed to be an original,  but all such counterparts  shall
together constitute but one and the same Agreement.

communications  provided  for  hereunder  shall  be in  writing  and  mailed  or

that is  prohibited  or  unenforceable  in any  jurisdiction  shall,  as to such
jurisdiction,   be   ineffective   to  the   extent  of  such   prohibition   or
unenforceability   without  invalidating  the  remaining  provisions  hereof  or
affecting  the  validity  or  enforceability  of  such  provision  in any  other
jurisdiction.  The  several  captions  to Sections  and  subsections  herein are
inserted  for  convenience  only  and  shall  be  ignored  in  interpreting  the
provisions  of  this  Agreement.  Each  schedule  or  exhibit  attached  to this
Agreement shall be incorporated herein an shall be deemed to be a part hereof.
