         subjects covered in all of the following example paragraphs:

         a.       Borrower is a Missouri corporation, duly formed, validly
                  existing and in good standing under the Laws of the state of
                  its organization and is duly qualified and authorized to do
                  business and is in good standing as a corporation in all
                  states or countries where the nature and extent of the
                  business transacted by it or the ownership of its assets makes
                  such qualification necessary, except where the failure to so
                  qualify will not have a Material Adverse Effect.

         b.       Borrower has all requisite power, authority and legal capacity
                  and legal rights to execute, deliver and perform the terms of
                  the Amendment.

         d.       The execution, delivery and performance of the Amendment by

                  time, or both) a default under (i) its Charter Documents or
                  (ii) any franchise, agreement, indenture, or other instrument

                  upon its property or assets.

         e.       Borrower has duly executed and delivered the Amendment and the
                  Amendment constitutes the Borrower's legal, valid and binding
                  obligation enforceable against it in accordance with its
                  terms.

         f.       The Person who signed the Amendment as an officer of Borrower

                  representations, warranties and covenants made by it in the
                  Amendment.

         g.       No consent, approval or other authorization of or by, or
                  registration or filing with, any Governmental Authority or
                  other Person is required in connection with the execution,

                  not already been obtained and a copy thereof delivered to
                  Administrative Agent.

         h.       No notice to or consent of any Guarantor is required in
                  connection with the Amendment to continue the enforceability
                  against such Guarantor of any Loan Document to which such
                  Guarantor is a party (including any Guaranty).

         i.       There are no actions, proceedings or investigations pending or
                  threatened against Borrower which might adversely affect the
                  validity or enforceability of the Amendment, the ability of

                  of Borrower.

4.       Add appropriate exceptions and limitations, all of which must be
