     Subject to the satisfaction of the conditions precedent set forth in, and
effective from and after the date specifically set forth in, Section 2 below,

Credit Agreement is hereby amended and restated in its entirety to read as
follows:

               "Borrowing Base" means, as of any time it is to be determined,
          the sum of:

               (a) 85% of the then net book value of Eligible Accounts (computed
          using the method of receivables valuation applied by the Borrower in
          accordance with GAAP which reflects such value as the net book value
          of its receivables, except that net book value for such purposes shall
          not reflect any reserve for accounts more than ninety days past due
          that have already been excluded from gross accounts in computing such
          Eligible Accounts) less such other reserves for uncollectibility,
          location of account debtor, contras and other matters as the Agent or
          Required Lenders in good

<PAGE>

          faith shall from time to time reasonably deem appropriate to adjust
          such net book value; plus

               (b) the lesser of (x) $13,000,000 and (y) 60% of the value
          (computed at its cost using the method of inventory valuation applied
          by the Borrower in accordance with GAAP which reflects such cost on
          the Borrower's books as its net book value, but in any event after
          reducing such value as so computed by the aggregate amount of all
          reserves for obsolescence, slow-moving items, shrinkage and all such
          other matters as the Agent or Required Lenders in good faith shall
          from time to time reasonably deem appropriate to adjust such net book
          value) of Eligible Inventory, provided that, in no event shall the
          amount computed pursuant to this clause (b) exceed 60% of the
          Borrowing Base; minus

               (c) a general reserve in the amount of $500,000;

          provided that (A) the Borrowing Base shall be computed only as against
          and on so much of the Collateral as is included on the certificates to
          be furnished from time to time by the Borrower pursuant to Section
          8.5(f) hereof and, if required by the Agent pursuant to any of the
          terms hereof or any Collateral Document, as verified by such other
          evidence required to be furnished to the Agent pursuant hereto or
          pursuant to any such Collateral Document, and (B) the Agent shall have
          the right to adjust the advance rates against Eligible Receivables and
          Eligible Inventory based solely on the commercially reasonable
          exercise of its credit judgment based on the results of any field
          audit of any Collateral which reasonably supports any such adjustment
          and the Agent shall notify the Borrower of any such adjustment to the
          advance rates promptly following such adjustment.

          Notwithstanding any other provision of this definition of "Borrowing
          Base" to the contrary: (i) the amount of Eligible Accounts otherwise
          included in the Borrowing Base shall be reduced, dollar for dollar, by
          a reserve equal to the greater of (a) the amount (if any) by which (x)
          the aggregate amount of accounts payable owing by the Borrower and its
          Subsidiaries to Deere and Caterpillar together and their respective
          Affiliates for inventory and supplies purchased (the
          "Deere/Caterpillar Payables") at any time exceeds (y) $8,000,000 or
          (b) the sum of (A) the amount (if any) by which (x) the aggregate
          amount of accounts payable owing by the Borrower and its Subsidiaries
          to Deere and its Affiliates for inventory and supplies purchased (the
          "Deere Payables") at any time exceeds (y) $5,000,000 and (B) the
          amount (if any) by which (x) the aggregate amount of accounts payable
          owing by the

                                      -2-

          Borrower and its Subsidiaries to Caterpillar and its Affiliates for
          inventory and supplies purchased (the "Caterpillar Payables") at any
          time exceeds (y) $4,000,000; (ii) no reserve will be imposed in
          computing the Borrowing Base as of any time solely in respect of the
          Deere/Caterpillar Payables, Deere Payables or Caterpillar Payables to
          the extent the same do not exceed such respective limits; and (iii)
          the Agent and the Required Lenders shall have the right to impose
          reserves for other matters arising in connection with receivables
          owing by Deere and Caterpillar and to otherwise impose reserves in
          accordance with the Credit Agreement.

counsel may reasonably request;

        (c) legal matters incident to the execution and delivery of this

        (a) this Amendment has been duly authorized by all necessary corporate

constitutes the legal, valid and binding obligation of the Company, and is
enforceable against the Company in accordance with its terms;

        (b) upon the effectiveness of this Amendment, the Company hereby

Purchase Agreement and the other Operative Documents, to the extent that the
same are not amended hereby, are true and complete in all material respects as
if remade as of the effective date of this Amendment (except to the extent
stated to relate to a specific earlier date, in which case such representations,
warranties and covenants are true and correct as of such earlier date); and

        (c) no Event of Default exists under the Purchase Agreement.

"hereunder,"

                                       2
<PAGE>

"hereof," "herein" or words of like import shall mean and be a reference to the
Agreement as amended hereby (except that for all purposes, the "date hereof" and
words of similar import shall mean June 23, 2004).

        (b) Except as specifically modified above, the Purchase Agreement and
all other documents, instruments and agreements executed and/or delivered in
connection therewith shall remain in full force and effect, and are hereby
ratified and confirmed.

        (c) The execution, delivery and effectiveness of this Amendment shall
not operate as a waiver of any right, power or remedy of the Agent or the
Purchasers, nor constitute a waiver of any provision of the Purchase Agreement
or any other documents, instruments or agreements executed and/or delivered in
connection therewith (except as expressly set forth herein). Nothing herein
shall constitute a waiver by the Agent or the Purchasers of any existing or
hereafter arising Event of Default nor shall the Agent's and the Purchasers'
execution and delivery of this Amendment establish a course of dealing among the
Agent, the Purchasers, the Company or any other obligor or in any other way
obligate the Agent or any of the Purchasers to provide hereafter any further
consents, waivers or modifications with respect to the Purchase Agreement.

     6. Collateral Documents. The Company may have herewith and heretofore
executed and delivered to the Agent, on behalf of the Purchasers, certain
Operative Documents, and the Company hereby acknowledges and agrees that,
notwithstanding the execution and delivery of this Amendment, the Operative
Documents remain in full force and effect and the rights and remedies of the
Agent and the Purchasers thereunder, the obligations of the Company thereunder
and the liens and security interests created and provided for thereunder remain
in full force and effect and shall not be affected, impaired or discharged
hereby. Nothing herein contained shall in any manner affect or impair the
priority of the liens and security interests created and provided for in the
Operative Documents as to the indebtedness which would be secured thereby prior
to giving effect to this Amendment.

     7. Expenses. The Company agrees to pay on demand all costs and expenses of
or incurred by the Agent and the Purchasers in connection with the negotiation,
preparation, execution and delivery of this Amendment and the other instruments
and documents executed and delivered in connection with the transactions
described herein (including the filing or recording thereof), including the fees
and expenses of counsel for the Agent and the Purchasers.

     8. Governing Law. This Amendment shall be governed by and construed in
accordance with the internal laws (as opposed to the conflict of law provisions)
of the State of Illinois.

     9. Headings. Section headings in this Amendment are included herein for
convenience of reference only and shall not constitute a part of this Amendment
for any other purpose.

     10. Counterparts; Telefacsimile. This Amendment may be executed by one or
more of the parties to the Amendment on any number of separate counterparts, and
all of said counterparts taken together shall be deemed to constitute one and
the same instrument. Delivery

                                       3
<PAGE>

of an executed counterpart of this Amendment by telefacsimile shall be equally
as effective as delivery of a manually executed counterpart of this Amendment.
Any party delivering an executed counterpart of this Amendment by telefacsimile
shall also deliver a manually executed counterpart of this Amendment, but the
failure to deliver a manually executed counterpart shall not affect the
validity, enforceability, and binding effect of this Amendment.

     11. No Strict Construction. The parties hereto have participated jointly in
the negotiation and drafting of this Amendment and the Purchase Agreement. In
the event an ambiguity or question of intent or interpretation arises, this
Amendment and the Purchase Agreement as hereby amended shall be construed as if
drafted jointly by the parties hereto, and no presumption or burden of proof
shall arise favoring or disfavoring any party by virtue of the authorship of any
provisions of this Amendment or the Purchase Agreement.

     12. Effectuation. The amendments to the Purchase Agreement contemplated by
this Amendment shall be deemed effective immediately upon the full execution of
this Amendment and without any further action required by the parties hereto.
There are no conditions precedent or subsequent to the effectiveness of this
Amendment.

     13. Counterparts. This Amendment may be executed in two or more
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument. One or more counterparts
of this Amendment may be delivered by facsimile, with the intention that
delivery by such means shall have the same effect as delivery of an original
counterpart thereof.
