1.   ACCURACY OF RECITALS.

Borrower acknowledges the accuracy of the Recitals.

2.   MODIFICATION OF LOAN DOCUMENTS.

     2.1  The Loan Documents are modified as follows:

        2.1.1  Section 1.2 of the Loan Agreement is modified to read in its
               entirety as follows:

             1.2  ADVANCES.  Subject to the terms and conditions hereof,
             Advances of the Loan will be made in amounts not to exceed the
             amount ('Borrowing Base') calculated in accordance with the formula
             set forth in the Borrowing Base Certificate, attached hereto as
             Exhibit A and by this reference incorporated herein. In calculating
             the Borrowing Base, the percentage set forth in Section 13 hereof
             of the amount of Total Eligible Accounts Receivable of Borrower and
             B & K Steel Fabrications, Inc., an Arizona corporation ('B&K')
             (collectively, 'Entities'), and the percentage set forth in Section
             13 hereof of the amount (determined on the basis of the lower of
             cost or market value) of Total Eligible Inventory of the Entities
             shall be used. 'Eligible Account

                                       1

     Receivable' is an amount owing to the Entities, as determined by Bank in
     its sole and absolute discretion, which has arisen from the delivery and/or
     shipment of products previously made and from services rendered for which
     an invoice has been issued by one of the Entities to its customer
     ('Customer') (a) which amount is not subject to any offset, counterclaim or
     defense asserted by the Customer, (b) which amount is subject to a
     perfected security interest in favor of Bank and is not subject to any
     other security interest, lien, claim or encumbrances, (c) which amount has
     not remained unpaid for more than the number of days set forth in Section
     13 after the date due under the terms of the related invoice, (d) where not
     more than fifteen percent (15%) of the total amount owing from the Customer
     has remained unpaid for more than the number of days set forth in Section
     13 after the date due under the terms of the related invoice, (e) which
     amount is not an uninsured amount owing from Customer located in a foreign
     country and (f) which amount is not owing from the United States of America
     or any agency, department or subdivision thereof, unless a properly
     executed assignment of claims has been received by Bank. 'Eligible
     Inventory' is the inventory of the Entities (consisting of those items
     within the categories set forth in Section 13), as determined by Bank in
     its sole and absolute discretion, to be (a) in good condition and salable
     in the ordinary course of the Entities' business, (b) owned by one of the
     Entities free and clear of any mortgages, liens, security interests,
     claims, encumbrances or rights of others, excepting only the security
     interests in favor of Bank, (c) located at a location identified in a
     Security Agreement (hereinafter defined), (d) subject to a perfected
     security interest in favor of Bank, (e) not subject to any consignment to
     any Customer and (f) not acquired by any of the Entities in or as part of a
     bulk transfer of sale or assets unless one of the Entities has complied
     with all applicable bulk sales or bulk transfer laws. Notwithstanding
     anything in this paragraph to the contrary, Borrower shall be entitled to
     Advances of the Loan of at least $1,000,000.00 regardless of the Borrowing
     Base calculation.

2.1.2  Section 1.5 of the Loan Agreement is hereby modified to read in its
     entirety as follows:

     1.5  REMITTANCE ACCOUNT.  If so indicated in Section 13 hereof, the
     proceeds received by either of the Entities from its inventory and
     collection of accounts receivable, which, pursuant to the Security
     Agreements (hereinafter defined), are required to be transmitted to Bank,
     shall be handled and administered by Bank in and through a remittance
     account in accordance with the provisions of the Security Agreements.

2.1.3  Section 2.1 and 2.2 of the Loan Agreement are hereby modified to read in
     their entirety as follows:

     2.1  SECURITY AGREEMENTS.  As security for the payment of the Note, the
     Loan, and all other liabilities and obligations of Borrower to Bank, now
     existing or hereafter created, Borrower shall grant and cause B&K to grant,
     to Bank a security interest in all of the Entities' inventory, accounts
     receivable, rights to payment and such other property ('Property'), as more
     particularly described in one or more security agreements ('Security
     Agreements') executed by the Entities and delivered to Bank in form and
     substance satisfactory to Bank, in its sole and absolute discretion. The
     Security Agreements shall grant to Bank a first and prior security interest
     in and to the Property, except as otherwise expressly provided therein.

     2.2  ADDITIONAL DOCUMENTS.  Borrower shall execute and cause B&K to execute
     from time to time upon the request of Bank, such financing statements or
     other documents reasonably required by bank to perfect or continue Bank's

     entirety as follows:

          absolute discretion certified copies of resolutions of the Boards of
          Directors of Borrower and B&K, authorizing Borrower and B&K to

                business or financial condition of Borrower or any guarantor
                since the date of the latest financial statements given to
                Bank by on behalf of Borrower or such guarantor;
                (e) Each of the warranties and representations made by

                correct as of the date of each Advance; and

                covenants, obligations and agreements on its part to be kept
                and performed under the Loan Documents and no Event of Default,
                or act or event which with the giving of notice or the passage

                hereunder or under any of the other Loan Documents, shall have
                occurred and be continuing.
