Agreement, or (iii) will violate any provision of the Borrower's certificate of
incorporation or by-laws or the certificate of incorporation or bylaws (or
equivalent organizational or other charter documents) of any of its respective

                                      -15-THIRD AMENDMENT TO
                              AMENDED AND RESTATED
                            EWP BRIDGE LOAN AGREEMENT

     This  THIRD   AMENDMENT  TO  AMENDED  AND  RESTATED  LOAN  AGREEMENT  (this
"Amendment")  is made and  entered  into as of June 30,  2003  between  KEYSTONE
CONSOLIDATED  INDUSTRIES,  INC., a Delaware  corporation  ("Keystone"),  and the
lenders listed in Annex I hereto (individually a "Lender" and collectively,  the
"Lenders").

                                    Recitals

     A.  Keystone and the Lenders  have  entered  into that certain  Amended and
Restated EWP Bridge Loan Agreement  dated as of November 21, 2001, as amended by
the First  Amendment to Amended and Restated EWP Bridge Loan Agreement  dated as
of March 18, 2002 between Keystone and the Lenders and as further amended by the
Second  Amendment to Amended and Restated EWP Bridge Loan Agreement  dated as of
December 31, 2002  between  Keystone  and the Lenders  (collectively,  the "Loan
Agreement").

     B.  Keystone and the Lenders  wish to amend the Loan  Agreement as provided
herein.

     C. Capitalized  terms used but not otherwise  defined herein shall have the
same meanings given to such terms in the Loan Agreement.

                                    Agreement

     In  consideration  of the foregoing and the mutual covenants and agreements
herein, the parties hereto do hereby agree as follows.

     Section 1. Amendment to Loan  Agreement.  Section 3.3 of the Loan Agreement
shall be amended by deleting  such section in its entirety and replacing it with
the following:

          3.3.  Maturity  Date.  Unless the same shall  become due  earlier as a
     result of acceleration of the maturity,  the Loans shall mature on July 31,
     2003 (the "Maturity Date"), at which time the outstanding principal balance
     of the Loans and all accrued and unpaid  interest and commitment fees shall
     become due and payable.

     Section 2. Effect on Loan Agreement and Notes.  Upon the  effectiveness  of
this Amendment,  all Notes outstanding  immediately prior to such  effectiveness
shall be deemed  amended as  necessary or  appropriate  to reflect the terms and
conditions set forth in the Loan Agreement as modified by this Amendment, and in
the event of a conflict between any term or condition of such Notes and the Loan
Agreement  as so modified,  the Loan  Agreement  as so modified  shall  control,
notwithstanding  any  provision  of such  Notes  or the  Loan  Agreement  to the
contrary.  Except as modified by this  Amendment,  the Loan  Agreement  and such
Notes  are in  all  respects  ratified  and  confirmed  and  all  of the  terms,
conditions and provisions thereof shall remain in full force and effect.

     Section 3. Governing Law. This Amendment shall be governed by and construed
in accordance  with the laws of the state of Texas without  giving effect to any
choice or conflict of law  provision  or rule  (whether of the state of Texas or
any other  jurisdiction)  that would  cause the  application  of the laws of any
jurisdiction other than the state of Texas.

     Section 4. Headings.  The section headings  contained in this Amendment are
for  reference  purposes  only and will not  affect  in any way the  meaning  or
interpretation of this Amendment.

     Section  5.  Counterparts;  Facsimile.  This  Amendment  may be  separately
executed  in  counterparts  and by the  different  parties  hereto  in  separate
counterparts,  each of which when so executed  shall be deemed to constitute one
and the same Amendment. This Amendment when executed may be validly delivered by
facsimile or other electronic transmission.

     Section  6.  Severability.   Any  provision  of  this  Amendment  which  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.
