Exhibit 10.18

SONIC CORP. SENIOR EXECUTIVE CASH INCENTIVE PLAN

LONG-TERM AWARD AGREEMENT

This Award Agreement (the “Agreement”), effective as of ___________ (the “Grant Date”), sets forth the grant of a long-term cash incentive award (the “Award”) by Sonic Corp., a Delaware corporation (the “Company”), pursuant to the provisions of the Sonic Corp. Senior Executive Cash Incentive Plan, as amended or restated from time to time (the “Plan”). 

This Agreement is only applicable to the long-term cash incentive award granted to the Participant on the Grant Date.  If the Participant receives or has received any other award under the Plan, it shall be governed by the terms of the applicable award agreement, which may be different from those set forth herein.  By accepting Award, the Participant agrees to the terms and conditions set forth in this Agreement, the Plan and the attached Award Notice (the “Notice”), which we collectively refer to as the "Plan Documents."

All capitalized terms shall have the meanings ascribed to them in the Plan, unless specifically set forth otherwise herein. 

1.Grant of Award. The Company hereby grants to the individual set forth in the Notice (the “Participant”) the Award subject to the terms and conditions of the Plan and this Agreement as follows.  The Performance Period, Target Amount and Performance Targets applicable to the Award are set forth in the Notice. 

2.Determination of Award.  As soon as administratively practicable after the end of the Performance Period, in accordance with Section 4(b) of the Plan, the Committee shall certify in writing (a)  the level of attainment of the Performance Targets and (b) the incentive amounts earned by the Participant pursuant to the Award.  Notwithstanding the level attained for each Performance Target, the Committee may reduce the amount payable to the Participant with respect to the Award based on factors the Committee deems relevant. 

3.Payment of Award.  The incentive amount for an Award determined pursuant to Section 2 shall be paid in cash on a date determined by the Committee in its sole discretion (the “Payment Date”) after the end of the Performance Period, but in no event later than the fifteenth day of the third month following the last day of the Performance Period.

4.Termination of Employment. 

(a)Disability or Death; Without Cause.  If the Participant’s employment with the Company and its Subsidiaries (the “Company Group”) terminates during the Performance Period due to the Participant’s death or Disability or the Participant’s termination by the Company Group without Cause, the Participant shall receive a payment with respect to the Award equal to the actual incentive amount determined in accordance with Section 2 multiplied by a fraction, the numerator of which is the number of months transpired from the first day of the

1

Performance Period until the last day of the month in which the death, Disability or termination without Cause occurred, and the denominator of which is the number of months in the Performance Period.  The Award earned pursuant to this Section 4(a) shall be paid to the Participant (or his beneficiary or estate, as applicable) on the Payment Date.     

(b)Change of control.  In the event that during a Performance Period (i) a Participant’s employment with the Company Group is actually or constructively terminated during the Performance Period and (ii) a Change in Control shall have occurred within the 365 days immediately preceding the date of such termination, then the Participant shall receive a payment with respect to the Award equal to the actual incentive amount determined in accordance with Section 2 multiplied by a fraction, the numerator of which is the number of months transpired from the first day of the Performance Period until the last day of the month in which the termination occurred, and the denominator of which is the number of months in the Performance Period.  The Award earned pursuant to this Section 4(a) shall be paid to the Participant on the Payment Date. 

(c)Other Terminations.  If the Participant’s employment with the Company Group terminates during the Performance Period for any reason other than as set forth in Section 4(a) or (b) (including as a result of a retirement or other voluntary termination by the Participant or a termination by the Company for Cause), the Award shall be cancelled and the Participant shall not be entitled to receive any payments with respect to the Award.

(d)Special Circumstances.  The Corporation shall have discretion to determine (a) if an authorized leave of absence, or absence in military or government service, shall constitute termination of employment for purposes of the Plan, (b) whether a Participant has ceased to be employed by the Corporation or any Affiliate, as appropriate, and (c) the effective date on which such employment terminated.
