Dear George,

On behalf of USA Truck, Inc. (the “Company”), I am pleased to offer you the position of Senior Vice President, Logistics, reporting to the Chief Executive Officer and President of the Company, with a start date no later than April 1, 2018. The following outlines the terms of employment, but does not constitute a contract of employment or a guarantee of employment. This offer is subject to approval by the Company’s Board of Directors and your compensation package as outlined is subject to approval of the Executive Compensation Committee of the Company’s Board of Directors (the “Committee”).

Base Salary. Your starting base salary will be $18,750.00 per month annualized to $225,000, less applicable taxes, deductions, and withholdings, paid monthly and subject to annual review. The Company’s regularly scheduled pay days are currently on the last day of every month.

Key Management Incentive Plan. You will participate in the established Key Management Incentive Plan, beginning in 2018 and you will be entitled to:

Cash Incentive. You are eligible for a target cash incentive of 50% of your annualized base salary, pro- rated based on the period of time you are employed at the Company during 2018 and less applicable taxes, deductions and withholdings. Target incentives do not constitute a promise of payment. To qualify for the incentive bonus, you must remain employed with the Company through the date that the incentive bonus is paid (as specified in the Key Management Incentive Plan). Your actual plan payout will depend on the Company’s and your individual performance relative to pre-established goals, subject to and governed by the terms and requirements of the Key Management Incentive Plan as determined by the Committee.

Equity Incentive. You are eligible for a target equity grant of restricted shares of the Company’s common stock equal to up to 75% of your annualized base salary for 2018 under the 2018 Equity Incentive Plan (the “2018 EIP”) to be established by the Committee. The number of restricted shares awarded will be based upon your annualized base salary and the closing price of the Company’s

common stock on the award date. Awards under the 2018 EIP will be 40% time-based and the balance will be performance-based. The time-based portion is expected to have a four (4) year ratable vesting period, and the performance-based portion is expected to vest at the completion of three (3) years, depending upon performance relative to goals established by the Committee. The maximum target achievable under the plan is 175% of your target performance based portion of the EIP program. All incentive compensation (whether cash or equity) for all employees, including you, is subject to the discretion of the Committee.

Upon the occurrence of a Payment Trigger described in subparagraph (ii) Paragraph (L) of Section 1 of Exhibit A hereto, all unvested shares subject to time-based vesting would become fully vested and any unvested shares subject to performance-based vesting would vest in accordance with the award agreement relating to such shares.

Sign-On Bonus. You also will receive a Sign-On Cash Bonus of $75,000, less applicable taxes, deductions, and withholdings. The Sign-On Bonus is payable in one installment and shall be payable to you on the first monthly paycheck that occurs 30 days or more after your start date.

If your employment is terminated by the Company for "Cause" (as defined in Exhibit A) or voluntarily by you at any time prior to the expiration of 24 months from your start date, this bonus will be subject to repayment on a pro-rated basis in relation to the portion of the 24-month period during which you are actually employed by the Company.

Obligations. You may be required to serve as an officer and/or director of one or more subsidiaries of the Company, for which you will receive no additional compensation.

Relocation Assistance. There is none offered, relocation to Van Buren, Arkansas is not required.

All benefits are subject to the plan documents and eligibility requirements.
