         (c) This Agreement and the other Debt Documents have been duly

performance by, Debtor of any of the Debt Documents, except such as may have

<PAGE>

         (e) The entry into, and performance by, Debtor of the Debt Documents
will not (i) violate any of the organizational documents of Debtor or any
judgment, order, law or regulation applicable to Debtor, or (ii) result in any
breach of, constitute a default under, or result in the creation of any lien,
claim or encumbrance on any of Debtor's property (except for liens in favor of
Secured Party) pursuant to, any indenture mortgage, deed of trust, bank loan,
credit agreement, or other agreement or instrument to which Debtor is a party;

         (f) There are no suits or proceedings pending or threatened in court or
before any commission, board or other administrative agency against or affecting
Debtor which could, in the aggregate, have a material adverse effect on Debtor,
its business or operations, or its ability to perform its obligations under the
Debt Documents;

         (g) All financial statements delivered to Secured Party in connection
with the Indebtedness have been prepared in accordance with generally accepted
accounting principles, and since the date of the most recent financial

and Debtor will not be negligent in the care and use thereof;

         (j) Debtor is, and will remain, the sole and lawful owner, and in

being contested in good faith and which do not involve, in the reasonable
judgment of Secured Party, any risk of the sale, forfeiture or loss of any of
the Collateral, and (iii) inchoate materialmen's, mechanic's, repairmen's and
similar liens arising by operation of law in the normal course of business for
amounts which are not delinquent (all of such permitted liens being hereinafter
referred to as "Permitted Liens").

3.       COLLATERAL.

         (a) Until the declaration of any default hereunder, Debtor shall remain
(except as otherwise provided for herein) in possession of the Collateral;
provided, however, that Secured Party shall have the right to possess (i) any
chattel paper or instrument that constitutes a part of the Collateral, and (ii)
any other Collateral which because of its nature may require that Secured
Party's security interest therein be perfected by possession. Secured Party, its
successors and assigns, and their respective agents, shall have the right to

hours. Upon any request from Secured Party, Debtor shall provide Secured Party
with notice of the then current location of the Collateral.

         (b) Debtor shall (i) use the Collateral only in its trade or business,
(ii) maintain all of the Collateral in good condition and working order, (iii)

possession of any of the Collateral (except to Secured Party or for maintenance
and repair), (ii) remove any of the Collateral from the continental United
States, Mexico or Canada, provided however that no more than ten percent (10%)
of the Collateral shall be outside of the United States at any given time, or

<PAGE>

rent, lease, mortgage, grant a security interest in or otherwise transfer or
encumber (except for Permitted Liens) any of the Collateral, provided however
Debtor may sell, rent or lease the Collateral to any member of its consolidated
group upon written notice to Secured Party.

         (d) Debtor shall pay promptly when due all taxes, license fees,
assessments and public and private charges levied or assessed on any of the
Collateral, on the use thereof, or on this Agreement or any of the other Debt
Documents. At its option, Secured Party may discharge taxes, liens, security
interests or other encumbrances at any time levied or placed on the Collateral
and may pay for the maintenance, insurance and preservation of the Collateral or
to effect compliance with the terms of this Agreement or any of the other Debt
Documents. Debtor shall reimburse Secured Party, on demand, for any and all
costs and expenses incurred by Secured Party in connection therewith and agrees
that such reimbursement obligation shall be secured hereby.

         (e) Debtor shall, at all times, keep accurate and complete records of
the Collateral, and Secured Party, its successors and assigns, and their
respective agents, shall have the right to examine, inspect, and make extracts
from all of Debtor's books and records relating to the Collateral at any time
during normal business hours.

         (f) If agreed by the parties, Secured Party may, but shall in no event
be obligated to, accept substitutions and exchanges of property for property,
and additions to the property, constituting all or any part of the Collateral.
Such substitutions, exchanges and additions shall be accomplished at any time
and from time to time, by the substitution of a revised Collateral Schedule for
the Collateral Schedule now or hereafter annexed. Any property which may be
substituted, exchanged or added as aforesaid shall constitute a portion of the
Collateral and shall be subject to the security interest granted herein.
Additions to, reductions or exchanges of, or substitutions for, the Collateral,
payments on account of any obligation or liability secured hereby, increases in
the obligations and liabilities secured hereby, or the creation of additional
obligations and liabilities secured hereby, may from time to time be made or
occur without affecting the provisions of this Agreement or the provisions of
any obligation or liability which this Agreement secures.

         (g) Any third person at any time and from time to time holding all or
any portion of the Collateral shall be deemed to, and shall, hold the Collateral
as the agent of, and as pledge holder for, Secured Party. At any time and from
time to time, Secured Party may give notice to any third person holding all or
any portion of the Collateral that such third person is holding the Collateral
as the agent of, and as pledge holder for, the Secured Party.

4.       ASSIGNMENT OF RESIDUAL AGREEMENTS.

             (a) Debtor hereby conveys, transfers and assigns to Secured Party,
all of Debtor's rights, interest and privileges which Debtor has or may have in
or arising from any and all Residual Agreements, now existing or hereafter made
between Debtor and Wabash National Corporation (the "Residual Agreements") with
respect to the Collateral.

             (b) Until an Event of Default (as described in Section 8) occurs,
this assignment shall not affect the right of Debtor to exercise any rights of
Debtor arising from such Residual Agreements.

5.       INSURANCE.

         The Collateral shall at all times be held at Debtor's risk, and Debtor
shall keep it insured against loss or damage by fire and extended coverage
perils, theft, burglary, and for any or all Collateral which are vehicles, for
risk of loss by collision, auto liability insurance as required by law, and
where requested by Secured Party, against other risks as required thereby, for
the full

                                       3

<PAGE>

replacement value thereof, with companies, in amounts and under policies
acceptable to Secured Party. Debtor shall deliver to Secured Party policies or
certificates of insurance evidencing such coverage. Each policy shall name
Secured Party as loss payee thereunder, shall provide for coverage to Secured
Party regardless of the breach by Debtor of any warranty or representation made
therein, shall not be subject to co-insurance, and shall provide for thirty (30)
days written notice to Secured Party of the cancellation or material
modification thereof. Debtor hereby appoints Secured Party as its attorney in
fact to make proof of loss, claim for insurance and adjustments with insurers,
and to execute or endorse all documents, checks or drafts in connection with
payments made as a result of any such insurance policies. Unless an Event of
Default shall have occurred and be uncured, Debtor shall have the right to
collect the proceeds of insurance and to use such proceeds to replace or repair
the Collateral. If Debtor chooses not to exercise such right or such right is
not available, proceeds of insurance shall be applied, at the option of Secured
Party, to repair or replace the Collateral or to reduce any of the Indebtedness
secured hereby.

6.       REPORTS.

         (a) Debtor shall promptly notify Secured Party in the event of (i) any
change in the name of Debtor, (ii) any relocation of its chief executive
offices, (iii) any relocation of any of the Collateral, (iv) any of the
Collateral being lost, stolen, missing, or destroyed, or (v) any lien, claim or
encumbrance attaching or being made against any of the Collateral other than
Permitted Liens.

         (b) Upon request, Debtor will, within thirty (30) days after the date
on which they are filed, deliver to Secured Party all Forms 10-K and 10-Q filed
with the Securities and Exchange Commission by its parent with respect to its
consolidated group. Upon request, Debtor will deliver to Secured Party one copy
of each financial statement, report, notice or proxy statement sent by Debtor's
parent to shareholders generally and one copy of each regular or periodic
report, registration statement or prospectus filed by Debtor's parent with any
securities exchange or the Securities and Exchange Commission or any successor
agency, such copies to be delivered to Secured Party within thirty (30) days
after they become available or are otherwise filed. Any and all financial
statements submitted and to be submitted to Secured Party have and will have
been prepared on a basis of generally accepted accounting principles, and are
and will be complete and correct and fairly present Debtor's parent's financial
condition as at the date thereof. Secured Party may at any reasonable time
examine the books and records of Debtor and make copies thereof.

         (c) Within thirty (30) days after any request by Secured Party, Debtor
will furnish a certificate of an authorized officer of Debtor stating that he
has reviewed the activities of Debtor and that, to the best of his knowledge,
there exists no Event of Default or event which with notice or lapse of time (or
both) would become an Event of Default.

7.       FURTHER ASSURANCES.

         (a) Debtor shall, upon request of Secured Party, furnish to Secured
Party such further information, execute and deliver to Secured Party such
documents and instruments (including, without limitation, Uniform Commercial
Code financing statements) and do such other acts and things, as Secured Party
may at any time reasonably request relating to the perfection or protection of
the security interest created by this Agreement or for the purpose of carrying
out the intent of this Agreement. Without limiting the foregoing, Debtor shall
cooperate and do all acts deemed necessary or advisable by Secured Party to
continue in Secured Party a perfected first security interest in the Collateral,
and shall obtain and furnish to Secured Party any subordinations, releases,
landlord, lessor, or mortgagee waivers, and similar documents as may be from
time to time requested by, and which are in form and substance satisfactory to,

name and generally to act on behalf of Debtor to execute and file applications
for title, transfers of title, financing statements, notices of lien and other
documents pertaining to any or all of the Collateral. Debtor shall, if any
certificate of title be required or permitted by law for any of the Collateral,
obtain such certificate showing the lien hereof with respect to the Collateral
and promptly deliver same to Secured Party.

         (c) Debtor shall indemnify and defend the Secured Party, its successors
and assigns, and their respective directors, officers and employees, from and

directly or indirectly, in connection with any of the Collateral.

<PAGE>

         (l) Any dissolution, termination of existence, merger or consolidation
(other than a merger or consolidation with or into a member of Debtor's
consolidated group) of Debtor or any Guarantor (such action being referred to as
an "Event"), unless Secured Party shall have received thirty (30) days advance
notice of such Event, and upon the occurrence of such Event such person shall be
(x) organized and existing under the laws of the United States or any state, and
executes and delivers to Secured Party an agreement containing an effective
assumption by such person of the due and punctual performance of this Agreement;
and (y) Secured Party is reasonably satisfied as to the credit worthiness of
such person;

         (m) If Debtor or any Guarantor is a privately held corporation and

ratio equals or exceeds twice Debtor's consolidated group's debt-to-worth ratio
as of the date of this Agreement (unless Secured Party shall have given its
prior written consent thereto). As used herein, "debt-to-worth ratio" shall mean
the ratio of (x) total liabilities which, in accordance with generally accepted
accounting principles ("GAAP") would be included in the liability side of a

trademarks, bond discount and underwriting expenses, organization expense and
other intangibles, all determined in accordance with GAAP.

9.       REMEDIES ON DEFAULT.

         (a) Upon the occurrence of an Event of Default under this Agreement,
the Secured Party, at its option, may declare any or all of the Indebtedness,
including without limitation the Notes, to be immediately due and payable,
without demand or notice to Debtor or any Guarantor. The obligations and
liabilities accelerated thereby shall bear interest (both before and after any
judgment) until paid in full at the lower of thirteen and four tenths percent
(13.4%) per annum or the maximum rate not prohibited by applicable law.

         (b) Upon such declaration of default, Secured Party shall have all of
the rights and remedies of a Secured Party under the Uniform Commercial Code,
and under any other applicable law. Without limiting the foregoing, Secured
Party shall have the right to (i) notify any account debtor of Debtor or any
obligor on any instrument which constitutes part of the Collateral to make
payment to the Secured Party, (ii) with or without legal process, enter any
premises where the Collateral may be and take possession and/or remove said
Collateral from said premises, (iii) sell the Collateral at public or private
sale, in whole or in part, and have the right to bid and purchase at said sale,
and/or (iv) lease or otherwise dispose of all or part of the Collateral,
applying proceeds therefrom to the obligations then in default. If requested by
Secured Party, Debtor shall promptly assemble the Collateral and make it
available to Secured Party at a place to be designated by Secured Party which is
reasonably convenient to both parties. Secured Party may also render any or all
of the Collateral unusable at the Debtor's premises and may dispose of such
Collateral on such premises without liability for rent or costs. Any notice
which Secured Party is required to give to Debtor under the Uniform Commercial
Code of the time and place of any public sale or the time after which any
private sale or other intended disposition of the Collateral is to be made shall
be deemed to constitute reasonable notice if such notice is given to the last
known address of Debtor at least five (5) business days prior to such action.

                                       8

<PAGE>

         (c) Proceeds from any sale or lease or other disposition shall be
applied: first, to all costs of repossession, storage, and disposition including
without limitation attorneys', appraisers', and auctioneers' fees; second, to
discharge the obligations then in default; third, to discharge any other
Indebtedness of Debtor to Secured Party, whether as obligor, endorser,
guarantor, surety or indemnitor; fourth, to expenses incurred in paying or
settling liens and claims against the Collateral; and lastly, to Debtor, if
there exists any surplus. Debtor shall remain fully liable for any deficiency.

         (d) In the event this Agreement, any Note or any other Debt Documents
are placed in the hands of an attorney for collection of money due or to become
due or to obtain performance of any provision hereof, Debtor agrees to pay all
reasonable attorneys' fees incurred by Secured Party, and further agrees that
payment of such fees is secured hereunder.

         (e) Secured Party's rights and remedies hereunder or otherwise arising
are cumulative and may be exercised singularly or concurrently. Neither the
failure nor any delay on the part of the Secured Party to exercise any right,
power or privilege hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, power or privilege preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege. Secured Party shall not be deemed to have waived any of its rights
hereunder or under any other agreement, instrument or paper signed by Debtor
unless such waiver be in writing and signed by Secured Party. A waiver on any
one occasion shall not be construed as a bar to or waiver of any right or remedy
on any future occasion.

         (f) Secured Party may exercise any rights of Debtor arising under the
Residual Agreements.

         (g) DEBTOR HEREBY UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF
ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR
INDIRECTLY, THIS AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE
INDEBTEDNESS SECURED HEREBY, ANY DEALINGS BETWEEN DEBTOR AND SECURED PARTY
RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS,
AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN DEBTOR AND SECURED
PARTY. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND
ALL DISPUTES THAT MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION,
CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW
AND STATUTORY CLAIMS). THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE
MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT,
ANY OTHER DEBT DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO

(Street Address of Maker)      (Town)         (County)   (State)      (Zip Code)

FOR VALUE RECEIVED, U.S. XPRESS LEASING, INC. ("Maker") promises, jointly and
severally if more than one, to pay to the order of Transport International Pool,
Inc. or any subsequent holder hereof (each, a "Payee") at its office located at
426 West Lancaster Avenue, Devon, PA 19333 or at such other place as Payee may
designate, the principal sum of ___________ Dollars ($______________ ), with
interest thereon, from the date hereof through and including the dates of
payment, at a fixed interest rate of eight and four tenths percent (8.4%) per
annum, to be paid in advance in lawful money of the United States, in
____________ (_____) consecutive monthly installments of principal and interest
of _________________Dollars ($______________ ) each (each, a "Periodic
Installment") and a final installment in the amount of $_______________. The
first Periodic Installment shall be due and payable on December 21, , 2001, and
the following Periodic Installments and the final installment shall be due and
payable on the same day of each succeeding month (each, a "Payment Date"). Such
installments have been calculated on the basis of 360 day year of twelve 30-day
months. Each payment may, at the option of the Payee, be calculated and applied
on an assumption that such payment would be made on its due date. Payments shall
be paid by wire transfer of immediately available funds to Bankers Trust, NY,
NY, Account No.: 50 233 099, ABA No. 021 001 033, or to such other account as
holder may request.

The acceptance by Payee of any payment which is less than payment in full of all
amounts due and owing at such time shall not constitute a waiver of Payee's
right to receive payment in full at such time or at any prior or subsequent
time.

The Maker hereby expressly authorizes the Payee to insert the date value is
actually given in the blank space on the face hereof.

This Promissory Note is secured by Collateral Schedule No. _____ to Master
Security Agreement dated __________________, 2001 ("Security Agreement.")

Time is of the essence hereof. If any installment or any other sum due under
this Note or any Security Agreement is not received within ten (10) days after
its due date, the Maker agrees to pay, in addition to the amount of each such
installment or other sum, a late payment charge of two percent (2%) of the
amount of said installment or other sum, but not exceeding any lawful maximum.
In the event that (i) Maker fails to make payment of any amount due hereunder
within ten (10) days after the same becomes due and payable; or (ii) Maker is in
default under, or fails to perform under any term or condition contained in any
Security Agreement following any applicable notice and/or cure period, then the
entire principal sum remaining unpaid, together with all accrued interest
thereon and any other sum payable under this Note or any Security Agreement, at
the election of Payee, shall immediately become due and payable, with interest
thereon at the lesser of 500 basis points over the fixed interest rate payable
hereunder or the highest rate not prohibited by applicable law from the date of
such accelerated maturity until paid (both before and after any judgment).

It is the intention of the parties hereto to comply with the applicable usury
laws; accordingly, it is agreed that, notwithstanding any provision to the
contrary in this Note or any Security Agreement, in no event shall this Note or
any Security Agreement require the payment or permit the collection of interest
in excess of the maximum amount permitted by applicable law. If any such excess
interest is contracted for, charged or received under this Note or any Security
Agreement, or if all of the principal balance shall be prepaid, so that under
any of such circumstances the amount of interest contracted for, charged or
received under this Note or any Security Agreement on the principal balance
shall exceed the maximum amount of interest permitted by applicable law, then in
such event (a) the provisions of this paragraph shall govern and control, (b)
neither Maker nor any other person or entity now or hereafter liable for the
payment hereof shall be

<PAGE>

obligated to pay the amount of such interest to the extent that it is in excess
of the maximum amount of interest permitted by applicable law, (c) any such
excess which may have been collected shall be either applied as a credit against
the then unpaid principal balance or refunded to Maker, at the option of the
Payee, and (d) the effective rate of interest shall be automatically reduced to
the maximum lawful contract rate allowed under applicable law as now or
hereafter construed by the courts having jurisdiction thereof. It is further
agreed that without limitation of the foregoing, all calculations of the rate of
interest contracted for, charged or received under this Note or any Security
Agreement which are made for the purpose of determining whether such rate
exceeds the maximum lawful contract rate, shall be made, to the extent permitted
by applicable law, by amortizing, prorating, allocating and spreading in equal
parts during the period of the full stated term of the indebtedness evidenced
hereby, all interest at any time contracted for, charged or received from Maker
or otherwise by Payee in connection with such indebtedness; provided, however,
that if any applicable state law is amended or the law of the United States of
America preempts any applicable state law, so that it becomes lawful for the
Payee to receive a greater interest per annum rate than is presently allowed,
the Maker agrees that, on the effective date of such amendment or preemption, as
the case may be, the lawful maximum hereunder shall be increased to the maximum
interest per annum rate allowed by the amended state law or the law of the
United States of America.

The Maker and all sureties, endorsers, guarantors or any others (each such
person, other than the Maker, an "Obligor") who may at any time become liable
for the payment hereof jointly and severally consent hereby to any and all
extensions of time, renewals, waivers or modifications of, and all substitutions
or releases of, security or of any party primarily or secondarily liable on this
Note or any Security Agreement or any term and provision of either, which may be
made, granted or consented to by Payee, and agree that suit may be brought and
maintained against any one or more of them, at the election of Payee without
joinder of any other as a party thereto, and that Payee shall not be required
first to foreclose, proceed against, or exhaust any security hereof in order to
enforce payment of this Note. The Maker and each Obligor hereby waives
presentment, demand for payment, notice of nonpayment, protest, notice of
protest, notice of dishonor, and all other notices in connection herewith, as
well as filing of suit (if permitted by law) and diligence in collecting this
Note or enforcing any of the security hereof, and agrees to pay (if permitted by
law) all reasonable expenses incurred in collection, including Payee's actual
attorneys' fees.

THE MAKER HEREBY UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM
OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR INDIRECTLY, THIS
NOTE, ANY OF THE RELATED DOCUMENTS, ANY DEALINGS BETWEEN MAKER AND PAYEE
RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS,
AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN MAKER AND PAYEE. The
scope of this waiver is intended to be all encompassing of any and all disputes
that may be filed in any court (including, without limitation, contract claims,
tort claims, breach of duty claims, and all other common law and statutory
claims). THIS WAIVER IS IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER
ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS NOTE, ANY RELATED DOCUMENTS, OR
TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED
TRANSACTION. In the event of litigation, this Note may be filed as a written
consent to a trial by the court.

This Note and any Security Agreement constitute the entire agreement of the
Maker and Payee with respect to the subject matter hereof and supersedes all
prior understandings, agreements and representations, express or implied.

No variation or modification of this Note, or any waiver of any of its
provisions or conditions, shall be valid unless in writing and signed by an
authorized representative of Maker and Payee. Any such waiver, consent,
modification or change shall be effective only in the specific instance and for
the specific purpose given.

Any provision in this Note or any Security Agreement which is in conflict with
any statute, law or applicable rule shall be deemed omitted, modified or altered
to conform thereto.
