                               AMENDMENT NO. 3 TO
                           LOAN AND SECURITY AGREEMENT


         This Amendment No. 3 to Loan and Security Agreement (this "Amendment")
dated as of May 19, 2006, is by and among Borrowers (as defined below), the
undersigned Lenders and Bank of America, N.A., successor to Fleet Capital
Corporation, as Agent for the Lenders who are from time to time party to that
certain Loan and Security Agreement (as amended from time to time, and as
amended hereby, the "Loan Agreement") dated as of October 8, 2003, by and among
Neenah Foundry Company, a Wisconsin corporation ("Neenah"), as a Borrower, the
Subsidiaries of Neenah that are party thereto as Borrowers (Neenah and such
Subsidiaries are collectively, "Borrowers" and each, a "Borrower"), Fleet
Capital Corporation, as Agent and as a Lender, Wachovia Capital Finance
Corporation (Central), f/k/a Congress Financial Corporation (Central), as
Syndication Agent and as a Lender, General Electric Capital Corporation, as
Documentation Agent and as a Lender, and the other Lenders party thereto. All
capitalized terms used in this Amendment and not otherwise defined in this
Amendment shall have the same meanings herein as in the Loan Agreement.

         Borrowers have informed Agent and Lenders that on or before July 15,
2006 Tontine Capital Partners, L.P., a Delaware limited partnership ("Tontine")
may be purchasing additional shares of the outstanding Voting Stock of Ultimate
Parent so that Tontine may hold a majority of shares of the outstanding Voting
Stock of Ultimate Parent (the "Tontine Purchase Transaction"). If the Tontine
Purchase Transaction involves the purchase of sufficient shares of the Voting
Stock, the consummation of the Tontine Purchase Transaction would constitute an
Event of Default under subsection 10.1.10 of the Loan Agreement, since Tontine
Capital Partners, L.P. is not currently a Permitted Holder under the Loan
Agreement. Borrowers have requested that Agent and Lenders agree to amend the
Loan Agreement in several respects so as to permit the Tontine Purchase
Transaction to be consummated without resulting in an Event of Default under
subsection 10.1.10 of the Loan Agreement.

         Subject to each of the terms and conditions set forth herein, Agent and
the undersigned Lenders have agreed to the request described above.

         Now, therefore, the parties hereto hereby agree as follows:

         1. Amendments. Subject to the prior satisfaction of the conditions set
forth in Section 2 of this Amendment, and in reliance on the representations and
warranties set forth in Section 3 of this Amendment, the parties hereto agree to
amend the Loan Agreement as follows:

         (a) Subsection 8.2.6(i)(d) of the Loan Agreement is hereby amended and
restated in its entirety, as follows:

          "(d) repayments or prepayments of principal amounts owing under the
          Subordinated Bond Documents, redemptions or repurchases of
          Subordinated Bonds in open-market transactions or otherwise or
          payments of Deferrable Interest (excluding payments of Deferrable

<PAGE>


          Interest made pursuant to the foregoing clause (c)), so long as both
          immediately prior to and after giving effect to any such repayment,
          prepayment, redemption or repurchase, (1) no more than $20,000,000 in
          the aggregate has been applied toward such repayments, prepayments,
          redemptions and repurchases and payments of Deferrable Interest
          (excluding payments of Deferrable Interest made pursuant to the
          foregoing clause (c)) during the Term, (2) no Event of Default exists,
          (3) average Availability (as determined by Agent in its reasonable
          credit judgment) for the thirty (30) day period ending on the date of
          any such repayment, prepayment, redemption or repurchase (giving
          effect to such repayment, prepayment, redemption, repurchase or
          payment of Deferrable Interest for each day in such thirty (30) day
          period) is not less than $17,500,000 and (4) actual Availability (as
          determined by Agent in its reasonable credit judgment) on the date of
          any such repayment, prepayment, redemption, repurchase or payment of
          Deferrable Interest is not less than $17,500,000; provided, that in no
          event will any such repayment or prepayment be financed with Revolving
          Credit Loans if such prepayment or repayment is required due to a
          mandatory redemption of Subordinated Bonds resulting from a "Change of
          Control" under the Subordinated Bond Documents that was caused by the
          consummation of the Tontine Purchase Transaction;"

         (b) Subsection 10.1.10 of the Loan Agreement is hereby amended and
restated in its entirety, as follows:

          "10.1.10. Change of Ownership. (a) any transaction is consummated the
     result of which is that any Person other than the Permitted Holders becomes
     the beneficial owner, directly or indirectly, of, in the aggregate, more
     than 50% of the total Voting Stock of Ultimate Parent, whether as a result
     of the purchase of Securities of Ultimate Parent then outstanding, the
     issuance of Securities of Ultimate Parent, any merger, consolidation,
     liquidation or dissolution of Ultimate Parent or otherwise; (b) Continuing
     Directors no longer constitute a majority of the members of the board of
     directors of any of Neenah, Parent or Ultimate Parent; (c) Ultimate Parent
     shall cease to own and control, beneficially and of record (directly or
     indirectly), 100% of the issued and outstanding Securities of Parent; (d)
     Parent shall cease to own and control, beneficially and of record (directly
     or indirectly), 100% of the issued and outstanding Securities of Neenah;
     (e) Neenah shall cease to own and control, beneficially and of record
     (directly or indirectly), 100% of the issued and outstanding Securities of
     each other Borrower and each of its other Subsidiaries; (f) any "Change of
     Control" under and as defined in the Secured Bond Indenture shall occur,
     other than such a "Change of Control" occurring as a result of the
     consummation of the Tontine Purchase Transaction, or the selection of a
     majority of the members of the board of directors of Ultimate Parent by
     Tontine Capital Partners, L.P.; or


                                      -2-

     (g) any "Change of Control" under and as defined in the Subordinated Bond
     Indenture shall occur, other than such a "Change of Control" occurring as a
     result of the consummation of the Tontine Purchase Transaction, or the
     selection of a majority of the members of the board of directors of
     Ultimate Parent by Tontine Capital Partners, L.P."

         (c) The definition of the term Continuing Director contained in
Appendix A to the Loan Agreement is hereby amended and restated in its entirety,
as follows:

          "Continuing Director -- as of any date of determination, any member of
     the board of directors of Neenah, Parent or Ultimate Parent who (i) was a
     member of such board of directors as of the date of the Agreement, (ii) was
     nominated for election or elected to such board of directors with the
     affirmative vote of a majority of the Continuing Directors who were members
     of such board of directors at the time of such nomination or election or
     (iii) was selected by Tontine Capital Partners, L.P., MacKay Shields LLC,
     Citicorp Mezzanine III, L.P. or the Trust Company of the West."

         (d) The definition of the term Permitted Holders contained in Appendix
A to the Loan Agreement is hereby amended and restated in its entirety, as
follows:

          "Permitted Holders -- each of Tontine Capital Partners, L.P., MacKay
     Shields LLC, Citicorp Mezzanine III, L.P., Metropolitan Life Insurance
     Company, Exis Differential Holdings, Ltd., TCW Shared Opportunity Fund II,

     High Income Partners, Ltd. and TCW High Income Partners II, Ltd., together
     with the Related Persons and the Affiliates of each of such Persons."

         (e) A new definition of the term Tontine Purchase Transaction is hereby
inserted into Appendix A to the Loan Agreement, in appropriate alphabetical
order, as follows:

          "Tontine Purchase Transaction -- the purchase by Tontine Capital
     Partners, L.P., a Delaware limited partnership, of a portion of the Voting
     Stock of Ultimate Parent pursuant to (i) a Securities Purchase Agreement
     dated as of May 19, 2006 among Tontine Capital Partners, L.P. and certain
     holders of such Voting Stock and (ii) a Stock Purchase Agreement dated as
     of May 19, 2006 among Tontine Capital Partners, L.P. and certain holders of
     such Voting Stock."
