                              ADDITIONAL PROVISIONS


LATE PAYMENTS: In addition to promising to pay the total payments as set forth
above. Borrower promises to pay past due interest accrued from maturity on each
installment in default more than 10 days at the highest rate permitted by law.
Borrower also agrees to pay all expenses actually incurred, including attorney
fees, in collecting any amount payable under this Agreement, all to the extent
allowed by law.

PARTIES: As used herein, "Borrower" shall include all persons who sign as
"Borrower(s)." "Lender" shall mean Navistar Financial Corporation, its
successors and assigns. "Affiliates" shall include all entities directly or
indirectly controlling or controlled by or under common control with Lender
including but not limited to Harco Leasing Company, Inc. and Navistar Leasing
Company. Upon notice of assignment, Borrower agrees to make payments hereunder
directly to assignee. Assignee shall be entitled to all rights of Lender free
from any defense, set-off or counterclaim by the Borrower against the Lender,
except as required by law. Seller shall not be the agent of Lender for
transmission of payments or otherwise.

NO WARRANTIES BY LENDER: Borrower agrees that Lender is nether the seller nor
the manufacturer of the Goods, and has not made and does not make any
representation, warranty or covenant with respect to the Goods, either express
or implied, written or oral, including but not limited to any representation,
warranty or covenant with respect to condition, quality, safety, durability,
merchantability, or fitness for a particular purpose. Borrower selected the
Goods and hereby agrees that any and all claims that Borrower has or may in the
future have against the seller and/or manufacturer shall not be asserted as an
offset against Lender, including but not limited to any claims in product
liability.

USE OF PROPERTY: Borrower shall hold and use the Goods at its risk and expense
with respect to loss or damages, and taxes and charges of every kind; shall take
proper care of the Goods and shall not abuse or misuse the same; shall not sell,
assign or transfer its interest in the Goods or remove the Goods from the
jurisdiction in which they now reside without the prior written consent of
Lender; shall not use the Goods for any illegal purpose and shall not attach any
of the Goods to any real estate or to any other property in such a manner as to
become a part thereof. If Borrower fails to pay said taxes and said charges,
Lender may, at its election, either do so and charge same to Borrower or treat
such failure as a breach of condition of this agreement. Any amount so paid by
the Lender shall become a part of the indebtedness secured hereunder.

PHYSICAL DAMAGE INSURANCE: If a cost for physical damage insurance is included
in the Agreement, Borrower hereby assigns to Lender the right to cancel such
insurance. If any insurance included in this Agreement is cancelled, whether by
request of the Borrower or the Lender, or action of the Insurance Company,
Lender is hereby authorized on behalf of Borrower to receive any unearned
premium refund. If no cost of physical damage insurance is included in this
Agreement, Borrower agrees to promptly insure the goods at its own expense with
a company acceptable to the Lender against loss by fire, theft and collision for
the period of the term of this Agreement and in such amounts and upon such terms
as are acceptable to Lender. Borrower specifically covenants to name Lender as
loss payee as its interest may appear. Lender may, in its sole discretion, apply
any proceeds of insurance received by it to any indebtedness owed by Borrower to
Lender or its Affiliates.

PLACEMENT OF PHYSICAL DAMAGE INSURANCE: Unless Borrower provides Lender with
evidence of the insurance coverage required by this Agreement, Lender may, but
will not be obligated to, purchase insurance at Borrower's expense to protect
Lender's interest in the Goods. This insurance may, but need not, protect
Borrower's interests. The coverage that Lender purchases may not pay any claim
that Borrower makes or any claim that is made against Borrower in connection
with the Goods. Borrower may later cancel any insurance purchased by lender, but
only after providing Lender with evidence that Borrower has obtained other
insurance as required by the Agreement. If Lender purchases insurance for the
Goods, Borrower will be responsible for the costs of such insurance including
interest and any other charge Lender may impose in connection with the placement
of the insurance, until the effective date of the cancellation or expiration of
the insurance. The cost of the insurance may be added to Borrower's outstanding
balance due and owing Lender under the Agreement. The cost of the insurance may
be more than the cost of insurance Borrower may be able to obtain on its own.

SECURITY INTEREST: In order to secure performance and payment of the loans made
be Lender to Borrower and all of the Borrowers obligations and indebtedness
hereunder and of all other amounts due or to become due hereunder and to secure
each and every other obligation or indebtedness of every kind and description
and howsoever arising, now or hereafter owing by Borrower to Lender or its
Affiliates, Lender hereby retains, and Borrower hereby grants, a purchase money
security interest under the Uniform Commercial Code in and to the Goods
described above, together with all replacements, repairs and accessions thereto
and cash and the non-cash proceeds (including insurance proceeds) thereof. The
security interest hereby granted is a separate, independent security interest
that is in addition to, and not in substitution for, any and all security
interests heretofore or hereafter granted by Borrower to Lender. This Agreement
is not an amendment to or modification of, or a waiver or release by Lender of,
any term, provision or condition of any other agreement between Borrower and
Lender. Further, Lender hereby retains and Borrower hereby grants a security
interest in the proceeds of any physical damage, credit life and or disability
insurance for which a charge is stated above or which is supplied by Borrower,
and if a charge for any such insurance has been included in this Agreement, a
security interest in the refund of any unearned premiums in the event such
insurance is terminated or canceled for any reason. Borrower will not grant any
other security interest in and to the Goods described above, without the prior
written consent of Lender. Borrower shall cause or cooperate with Lender in
causing Lender's security interest in the Goods to become properly perfected
under state law through filing of a financing statement or notation on
appropriate perfection documents.

DEFAULT: For Use In All States Except Louisiana. Time is of the essence hereof
and if Borrower defaults in any one of the payment on the loan or other payment
provided for herein when due or breaches any other covenant or condition of this
Agreement, or any other contract or agreement between Borrower and Lender or its
affiliates or if the Goods are levied upon, or Borrower becomes bankrupt or
insolvent or a petition in bankruptcy is filed by or against the Borrower, then
Lender may, in its sole option and discretion in any such event declare the
total amount unpaid hereunder, including accrued delinquency charges, and
excluding unearned interest immediately due and payable and may take possession
of the Goods in a lawful manner wherever found without notice, demand or legal
process, or may require the Borrower to assemble the Goods and make it available
to the Lender at a place to be designated by the Lender, and where not
prohibited by law, may sell the same at public or private sale, with or without
notice, at which sale Lender may become the purchaser, may deduct from the
proceeds of any such sale all taxes and charges due on the Goods and all
expenses of taking, removing, holding, repairing and selling the Goods, and may
apply the net proceeds to any indebtedness of Borrower, returning to Borrower
any surplus or holding Borrower liable for any deficiency; and in consideration
of the use of the Goods and for diminution in saleable value thereof, Lender may
retain all payments made; or Lender may pursue any other remedy provided by law.
Lender may accept partial payments of any sum due without waiving or otherwise
modifying the terms of this Agreement and the waiver by Lender of a breach of
any condition of this Agreement shall not constitute a waiver of any subsequent
breach whether or not of a like character. In the event of bankruptcy or other
insolvency proceedings, in addition to the above remedies, the Lender shall be
entitled to any rental or other income produced by the Goods prior to its
release to Lender.

DEFAULT: For Use In Louisiana Only. Borrower does hereby confess judgement in
favor of the Lender or any subsequent holder of this agreement for principal,
interest, attorney's fees, and costs; and does hereby declare that if anyone of
the payments on the loan or other payment provided for herein is not fully paid
when due, if default be made in compliance with any condition or covenant
herein, or proceedings in bankruptcy, insolvency or receivership be instituted
by or against the Borrower, or if any action is taken looking toward the
appointment of a receiver, syndic or curata of Borrower or if the property be
used in violation of any state or Federal law, such violation shall constitute
a breach of this Agreement which shall ipso facto be immediately due and
exigible in its entirety and the Lender may cause all and singular the Goods
herein described to be seized and sold under executory or other legal process
in any court, without appraisement, to the highest bidder, payable in cash.
Borrower hereby specifically waives the three (3) day notice of demand provided

possession of the Goods wherever found without process of law and hold same
until the amount due and either at public or private sale without demand for
performance of without notice to the Borrower, with or without having the Goods
at the place of sale. The Lender, or future holder of this Agreement, shall
have the right to bid at any public sale. From the proceeds of such sale, the
Lender, or future holder of this Agreement, shall deduct all expenses for
retaking, repairing and selling the Goods, including a reasonable attorney's
fee.

CO-BORROWER: The obligation of any co-borrower hereunder shall be primary and
the co-borrower shall be jointly and severally liable with the Borrower for
payment in full of all amounts due or to become due pursuant to the terms and
conditions of this Agreement.

herein and in the credit application are true and correct as of the date hereof

equipment except as may be indicated herein. Renewal, extension, or assignment
of this Agreement shall not release Borrower or Co-Borrower from any
obligations hereunder.

to execute, sign, and file on Borrower(s) behalf any financing statement,
continuation statement or any other document related to the perfection or
protection of the security interest hereby created, if allowed by law.

APPLICATION OF PAYMENTS: Each payment received on the loan shall be applied
first to accrued interest and delinquency charges and then to the balance of any
amount financed then outstanding.

SAVINGS CLAUSE: Should any provision of this Agreement be or become invalid,
illegal, prohibited or unenforceable by law or otherwise, then such provision
shall be void; however, such impairment shall not in any way invalidate or
impair the remainder of this Agreement or any other of its provisions. If the
rate of interest or other charges set forth hereunder shall exceed the
applicable maximum, then such rate shall be reduced to such maximum and any
excess interest or charge that may have been collected shall, at the option of
the Borrower, either be refunded in cash or applied as a credit to unpaid
principal. In no event shall Borrower be obligated to pay such excess charges.

ACCEPTANCE BY LENDER, CHOICE OF LAW: This Agreement is not binding until
accepted by Lender in Illinois. Except as prohibited by law, the construction
and validity of this Agreement shall be controlled by the law of Illinois,
where this Agreement is entered into, and applicable federal law. This
Agreement is entered into in Illinois and all loans made by the Lender will be
extended from Illinois. The validity and enforcement of the security interest
granted hereunder shall be controlled by the law of jurisdiction where the
Goods are to be kept and used.
