                                 USA TRUCK, INC.

                          EMPLOYEE STOCK PURCHASE PLAN

                 As Amended and Restated as of October 16, 2002

USA TRUCK, INC., a Delaware corporation (the "Company"), on this 16th day of
October, 2002, has amended and restated this Employee Stock Purchase Plan (the
"Plan"), which became effective on the date that public trading of the Company's
Common Stock, par value $.01 per share ("Common Stock"), commenced after the
completion of the initial public offering of the Common Stock (the "Effective
Date").

         1. Purpose. The purpose of the Plan is to provide a convenient means by
which the eligible employees of the Company may become stockholders in the
Company. The Board of Directors of the Company believes that it is desirable to
permit the employees of the Company to participate in the ownership of the
Company through the purchase of shares of Common Stock.

         2. Term of Plan. The Plan shall commence on the Effective Date and
remain in effect from year to year thereafter, but may be modified, amended,
restated or discontinued by the Board of Directors of the Company at any time.

         3. Eligibility. All regular full-time employees of the Company,
including executive officers, who have attained the age of majority in their
respective states of residence and have been employed continuously by the
Company for at least ninety (90) days shall be eligible to participate in the
Plan for so long as they remain employed by the Company. Employees of any
subsidiary of the Company that now or may hereafter exist shall also be eligible
to participate in the Plan, and the term "Company" as used herein shall be
deemed to include any such subsidiary to the extent appropriate. Notwithstanding
the foregoing, an employee shall not be eligible to participate in the Plan if
such employee owns stock possessing 5% or more of the total combined voting
power or value of all classes of stock of the Company or any parent or
subsidiary corporation of the Company (within the meaning of Section 424(e) and
(f) of the Internal Revenue Code of 1986, as amended (the "Code")). For purposes
of determining stock ownership under this paragraph, the rules of Section 424(d)
of the Code shall apply, and stock which the employee may purchase under the
Plan shall be treated as stock owned by the employee. For purposes of this
Section 3, the term "full-time employee" shall include any employee whose
customary employment is more than 30 hours per week and is for more than 180
days in any calendar year.

         4. Participation. Each person who will be an eligible employee on any
January 1, April 1, July 1 or October 1 (each, an "Enrollment Date") during the
term of the Plan may elect to participate in the Plan by executing and
delivering to the Company's Personnel Director, on or before the tenth day of
the immediately preceding month, a form to be furnished by the Company
(hereinafter referred to as a "payroll deduction authorization") authorizing and
instructing the Company to deduct from his or her payroll check for each pay
period a specified amount to be applied to the purchase of Common Stock for such
employee under the Plan. Such election shall become effective on the first
Enrollment Date following the Company's receipt of the payroll deduction
authorization form in accordance with the preceding sentence and shall remain in
effect until amended in accordance with this Section 4 or until such eligible
employee withdraws from participation in the Plan or his or her participation is
otherwise terminated.

         Each payroll deduction authorization shall request withholding, by
means of substantially equal payroll deductions over the Plan year (or the
remaining portion thereof following commencement of participation), of an amount
which shall not, for any pay period, exceed 40% of the employee's total base
compensation for such pay period. The payroll deduction authorized by the
employee shall not be less than Two Dollars ($2.00) per pay period, and payroll
deductions must be in whole dollar amounts only. If the employee's compensation
for any pay period is insufficient to permit the withholding of the requested
amount in compliance with the foregoing limitations, no withholding will be made
for the employee for such pay period.

<PAGE>

         A participant in the Plan may change his or her payroll deduction
amount by written notice delivered to the Company's Personnel Director on or
before the tenth day of the month immediately preceding any Enrollment Date with
respect to which the change is to be effective; provided, however, that no such
change shall be made less than six (6) months after any preceding change. A
payroll deduction amount may be decreased (but not increased) by a participating
employee on any other date upon a showing of special circumstances that, in the
opinion of the Board of Directors of the Company, warrant a decrease in such
amount.

         5. Withdrawal from the Plan. A participating employee may withdraw from
participation in the Plan at any time by signing and delivering to the Company's
Personnel Director a withdrawal notice. If the employee decides to re-enter the
Plan, the employee must deliver a new payroll deduction authorization to the
Company's Personnel Director in accordance with Section 4. Any participating
employee who withdraws from the Plan may not re-enter until six (6) months have
passed from the date of his or her withdrawal, and may do so only on an
Enrollment Date in accordance with Section 4.

         6. Purchase of Stock. On or before the fifth calendar day of each month
the Company will remit to the firm appointed by the Company to administer and
act as financial agent under the Plan (hereinafter referred to as the
"Administrator") the total of all deductions made under the Plan with respect to
the previous calendar month, except to the extent the Company has elected to
provide shares of Common Stock to the Administrator. The Company shall
determine, in its sole discretion, the portion of each month's deductions to be
applied to the purchase of shares from the Company and the portion to be
remitted to the Administrator. The Administrator will apply the funds received
to the purchase of shares of Common Stock on the open market. Shares supplied by
the Company shall be deemed purchased by participants on the sixth calendar day
of the month (or if there are no reported trades in the Common Stock on such
day, on the next succeeding trading day) at a price equal to the average of the
high and low sales prices of the Common Stock on the Nasdaq National Market
System (or such other exchange or stock market on which the Common Stock may
from time to time be traded) on such day. Shares purchased on the open market
shall be purchased at prevailing market prices within thirty (30) days following
the date of remittance of funds by the Company to the Administrator. Such
purchases will be made in the name of the Administrator for the account of the
USA Truck, Inc. Employee Stock Purchase Plan and will commence after the
remittance of one month's deductions to the Administrator. The total number of
shares of Common Stock that may be purchased by participating employees under
the Plan on and after January 1, 1998 (the date as of which the Plan was amended
to permit the Company to provide shares of Common Stock for purposes of the
Plan) shall be 200,000 shares, including shares purchased from the Company and
on the open market as provided herein.

         If the Administrator is unable to purchase the maximum number of shares
of Common Stock that would otherwise be purchasable with the remittance for any
calendar month, the shares that are purchased will be allocated pro rata among
the participating employees in proportion to their respective payroll deduction
amounts. The funds remaining with the Administrator after the purchase of such
shares will be returned to the Company by the Administrator no later than
thirty-five (35) days following the date of the Administrator's receipt of the
remittance. The Company will return such funds to the participating employees,
in proportion to their interests therein, as soon as practicable thereafter.

         Whenever shares are provided by the Company, the amount of the purchase
price deemed to be paid by participants to the Company therefor and the
equivalent amount of deductions that otherwise would be required to be remitted
by the Company to the Administrator in respect thereof shall be offset against
each other, so that no physical delivery of the funds so offset need occur. In
that event, the Company shall apply the deductions to the purchase price of such
shares as determined in accordance with the Plan.

         7. Custody and Issuance of Stock. Each participating employee will be
credited by the Administrator each calendar month with his or her pro rata share
of the purchased shares, including fractional shares to the fourth decimal
place. Records of the Company maintained under the Plan will be confidential.
Each participating employee shall have the right at any time to require the
Administrator to release from custody the shares of Common Stock theretofore
purchased by or for such employee, and to receive a certificate or certificates
representing such whole shares of Common Stock and the cash equivalent of any
fractional shares. Stock certificates will be issued to a participating employee
in accordance with this paragraph upon written request to the Administrator.
Such stock certificates will be registered in the name of the employee or in the
name of another person or persons as instructed by the employee and will be
delivered to the employee or to his or her order. The employee shall be
responsible for, and shall pay to the Administrator, any fees and charges of the
transfer agent and registrar for the Company's Common Stock in connection with
any issuance of stock certificates to or upon the order of such employee
pursuant to the Plan. The Administrator will convert fractional shares to cash
by selling them on the open market in the manner contemplated by Section 11 of
the Plan.

                                        2

         8. Stock Splits and Rights, Dividends and Other Distributions. Cash
dividends and other cash distributions received by the Administrator with
respect to the shares held in its custody hereunder will be credited pro rata to
the accounts of participating employees in accordance with their respective
interests in the shares with respect to which the dividends or distributions are
paid or made, and will be applied, as soon as practicable after receipt thereof
by the Administrator, to the purchase of additional shares of Common Stock for
the respective accounts of such employees. Stock splits or dividends paid in
shares of Common Stock that are received by the Administrator with respect to
shares held in its custody hereunder will be allocated to the participating
employees in whole shares and in fractional shares to the fourth decimal place
in accordance with their interests in the shares with respect to which the stock
dividends are paid or the stock split relates. Share options or rights or other
property, other than shares of Common Stock, received by the Administrator as
distribution on shares held in its custody hereunder shall be sold by the
Administrator for the accounts of the participating employees, and the
Administrator shall treat the proceeds of such sale in the same manner as cash
dividends received by the Administrator on shares held in its custody hereunder.

         In the event the Company shall effect a split of its outstanding Common
Stock or a dividend payable in Common Stock, or in the event the outstanding
Common Stock shall be combined into a smaller number of shares, the total number
of shares that may be purchased under the Plan on and after January 1, 1998, as
contemplated by Section 6, shall be increased or decreased proportionately.

         9. Expenses. Except as provided in Sections 7, 11 and 13 hereof, the
reasonable fees and charges of the Administrator and all costs of maintaining
records and executing transfers hereunder will be borne by the Company.
Brokerage fees and commissions for the purchase (but not the sale) of shares
shall also be borne by the Company. The Company will pay all costs incurred by
it in connection with payroll deductions. The Company will not make any
contributions to the Plan for the benefit of its employees, and each
participating employee will pay the full purchase price of the shares of Common
Stock purchased for his or her account pursuant to the Plan.

         10. Designation of Administrator. Subject to its right to terminate the
designation, the Company has designated Computershare Incorporated as the
Administrator hereunder. The Administrator is the financial agent who is charged
with the responsibility of safekeeping of funds paid in and the shares purchased
under the Plan, after receipt of remittance by the Company each calendar month,
and until the shares are issued to the employees or cash balances refunded.

         11. Sale of Shares. Upon notice from a participating employee to the
Administrator, shares of Common Stock credited to the participating employee's
account maintained by the Administrator may be sold by such employee at any time
while the employee remains employed with the Company. Such sale shall be made by
the Administrator, at market price, as the first available trade on the business
day next following the day on which it receives such notice from the employee.
The participating employee shall be responsible for, and shall pay, any fees or
charges of the Administrator, brokerage fees and commissions and other charges
identified with and incurred as a result of the sale. When the sale transaction
is consummated, the Administrator will forward to such employee a check for the
proceeds of the sale, net of the fees, commissions and other charges, together
with a statement detailing the terms of the sale, fees and commissions incurred
and remaining account balance.

         12. Responsibility. Neither the Company, the Administrator nor any
broker through whom purchase orders are executed shall have any responsibility
or liability, other than liabilities arising out of applicable securities laws,
for any act or thing done or left undone, including, without limiting the
generality of the foregoing, any action taken with respect to the price, time,
quantity or other conditions and circumstances of the purchase of shares, in
accordance with the terms of the Plan. A determination by the Board of Directors
of the Company as to any question that may arise regarding the Plan's conduct or
operation shall be final.

         13. Termination. In the event of the death or termination of employment
of a participating employee, the discontinuance of the Plan by the Company or
the election of a participating employee to withdraw from the Plan for any
reason, the participating employee, or in the event of death, such deceased
participant's designated beneficiary (or if no such beneficiary has been
designated, his or her legal representative in accordance with the applicable
laws of descent and distribution), shall have the right to elect to receive a
distribution of the shares of Common Stock being held for such employee's
account under the Plan or the cash equivalent thereof.

         If such employee, beneficiary or representative elects to receive
Common Stock, all full shares being held for the employee's account under the
Plan will be transferred to such employee, beneficiary or representative or to
his or her order, and a certificate or certificates evidencing such shares will
be delivered as promptly as practicable, subject to the receipt by the
Administrator of documentation properly evidencing the

                                        3

<PAGE>

rights and authority of the beneficiary or representative of any deceased
employee. Such employee, beneficiary or representative shall be responsible for,
and shall pay to the Administrator, any fees and charges of the transfer agent
and registrar for the Company's Common Stock in connection with the issuance of
stock certificates to or upon the order of such employee, beneficiary or
representative pursuant to this paragraph. Fractional share balances that have
been credited to the employee will be converted into cash through sale by the
Administrator, at market price, as soon as practicable after the employee's
termination of employment, death or withdrawal from the Plan, as the case may
be. In the event of discontinuance of the Plan, interests in fractional shares
will be liquidated by the Administrator in a like manner and the proceeds
distributed pro rata.

         If such employee, beneficiary or representative elects to receive cash,
all full and fractional shares being held for the employee's account under the
Plan will be sold for such employee, beneficiary or representative by the
Administrator in accordance with Section 11 of the Plan, subject to the receipt
by the Administrator of documentation properly evidencing the rights and
authority of the beneficiary or representative of any deceased employee. The
employee, beneficiary or representative shall be responsible for, and shall pay,
any fees or charges of the Administrator, brokerage fees and commissions and
other charges identified with and incurred as a result of the sale.

         14. Withholding Taxes. All amounts subject to withholding with respect
to each participating employee's (i) payroll deduction amounts under the Plan
and (ii) participation in the Plan will be deducted from such participating
employee's wages after reduction for his or her payroll deduction amounts, and
will not reduce the participating employee's payroll deduction amounts allocated
to the Plan hereunder.

         15. Stockholder Rights. Each participating employee shall at all times
be the beneficial owner of all shares of Common Stock being held for his or her
account under the Plan. The Administrator shall deliver to each participating
employee notices of stockholder meetings, proxy statements and other
communications distributed by the Company to its stockholders. Prior to the time
the Administrator makes delivery to the participating employee of the shares of
Common Stock hereunder, the Administrator will exercise all voting rights
pertaining to each participating employee's pro rata share of such shares in
accordance with written directions, if any, given to the Administrator by such
participating employee prior to the date fixed for such exercise; in the absence
of such directions, the Administrator will exercise such voting rights in
accordance with the applicable rules and regulations of the Securities and
Exchange Commission and the New York Stock Exchange then in effect.

         16. Statement of Account. The Administrator shall furnish each
participating employee with a statement promptly after the end of each Plan year
(and more frequently if the Board of Directors of the Company deems it
appropriate) indicating the dollar amount invested and the number of shares
purchased during the Plan year (or such shorter period as may be specified by
the Board of Directors of the Company), and the total number of shares (full and
fractional) credited to such employee's account, and such other pertinent
information as the Administrator may deem reasonable or necessary.

         17. Effective Date of the Plan. The Plan shall become effective, as of
the Effective Date, when it has been duly approved by the holders of at least a
majority of the shares of Common Stock present or represented and entitled to
vote at a meeting of the stockholders of the Company duly held in accordance
with applicable law within twelve months after the date of adoption of the Plan
by the Board. If the Plan is not so approved, the Plan shall terminate, any
election by an employee to participate in the Plan shall be null and void and
any funds accumulated under the Plan through payroll deductions shall be
returned to the appropriate employees.

         IN WITNESS WHEREOF, this Plan has been executed at Van Buren, Arkansas,
on this 16th day of October, 2002.
