EMPLOYMENT AGREEMENT

This Agreement is entered into effective as of the 11th day of April, 2012, by and between Sonic Corp. (the “Corporation”), a Delaware corporation, and James P. O’Reilly (the “Employee”).

RECITALS

Whereas, the Employee is currently serving as the Senior Vice President and Chief Marketing Officer of the Corporation and is an integral part of its management; and

Whereas, the Corporation’s Board of Directors (the “Board”) has determined that it is appropriate to support and encourage the attention and dedication of certain key members of the Corporation’s management, including Employee, to their assigned duties without distraction and potentially disturbing circumstances arising from the possibility of a Change in Control (herein defined) of the Corporation; and

Whereas, the Corporation desires to continue the services of Employee, whose experience, knowledge and abilities with respect to the business and affairs of the Corporation will be extremely valuable to the Corporation; and

Now, therefore, it is agreed as follows:

4.8 Compensation Defined. Compensation shall be defined as all monetary compensation and all benefits described in Articles III and IV hereunder (as adjusted during the term hereof).

ARTICLE V

Termination

5.1 Separation from Service. For purposes of this Agreement, the terms “terminate,” “terminated” and “termination” with respect to the Employee’s employment mean a termination of the Employee’s employment that constitutes a “separation from service” within the meaning of the default rules of Section 409A of the Code.

5.2 Death. Employee’s employment hereunder shall be terminated upon the Employee’s death.

5.3 Disability. The Corporation may terminate Employee’s employment hereunder in the event Employee is disabled and such disability continues for more than 180 days. “Disability” shall be defined as the inability of Employee to render the services required of him under this Agreement, with or without a reasonable accommodation, as a result of physical or mental incapacity.

3

5.4 Cause.

(a) The Corporation may terminate Employee’s employment hereunder for Cause. For the purpose of this Agreement, “Cause” shall mean (i) the willful and intentional failure by Employee to substantially perform Employee’s duties hereunder, other than any failure resulting from Employee’s incapacity due to physical or mental incapacity, or (ii) commission by Employee, in connection with Employee’s employment by the Corporation, of an illegal act or any act (though not illegal) which is not in the ordinary course of the Employee’s responsibilities and exposes the Corporation to a significant level of undue liability. For purposes of this paragraph, no act or failure to act on Employee’s part shall be considered to have met either of the preceding tests unless done or omitted to be done by Employee without a reasonable belief that Employee’s action or omission was in the best interest of the Corporation.

(b) Notwithstanding the foregoing, Employee shall not be deemed to have been terminated for cause unless such action is ratified by the affirmative vote of not less than two-thirds of the entire membership of the Board at a meeting held within 30 days of such termination (after reasonable notice to Employee and an opportunity for Employee to be heard by members of the Board) confirming that Employee was guilty of the conduct set forth in this Section 5.4. Ratification by the Board will be effective as of the original date of termination of Employee.

5.5 Compensation Upon Termination for Cause or Upon Resignation By Employee. Except as otherwise set forth in Section 5.8 hereof, if Employee’s employment shall be terminated for Cause or if Employee shall resign Employee’s position with the Corporation, the Corporation shall pay Employee’s Compensation only through the last day of Employee’s employment by the Corporation. The Corporation shall then have no further obligation to Employee under this Agreement. If the Board, pursuant to Section 5.4(b), votes to classify Employee’s termination as “not for cause,” then Employee shall be compensated pursuant to Section 5.6 below.

5.6 Compensation Upon Termination Other Than For Cause Or Disability. Except as otherwise set forth in Section 5.8 hereof, if the Corporation shall terminate Employee’s employment other than for Cause or Disability, the Corporation shall continue to be obligated to pay 12 months’ of Employee’s Salary (payable in 24 equal installments, with the first installment occurring on the first regularly scheduled payroll date following the date of termination, and the remaining installments occurring on a semi-monthly basis thereafter), but shall not be obligated to provide any other benefits described in Articles III and IV hereof, except to the extent required by law.

5.7 Compensation Upon Non-Renewal of Agreement. Except as otherwise set forth in Section 5.8 hereof, if the Corporation shall give notice to Employee in accordance with Section 1.2 hereof that this Agreement will not be renewed but Employee’s employment is not terminated, the Corporation shall continue to be obligated to pay Employee’s Salary for a period of 12 months beginning on the date notice of non-renewal is given, on regularly scheduled payroll dates, but shall not be obligated to provide any other benefits described in Articles III and IV hereof, except to the extent required by law.

5.8 Termination of Employee or Resignation by Employee for Good Reason Following a Change in Control. If at any time within the first twelve months subsequent to a Change in Control, the Employee’s employment with the Corporation is terminated other than as provided for in Section 5.2, 5.3 or 5.4 hereof, or the Corporation violates any provision of this Agreement or Employee shall resign

4

Employee’s employment for Good Reason (as defined herein), the Corporation shall be obligated to pay to Employee a severance payment in an amount equal to two times the Employee’s compensation payable under paragraph 5.6 above, but in no event to exceed an amount equal to $1.00 less than three (3) times the mean average annual compensation paid to Employee by the Corporation and any of its subsidiaries during the five calendar years ending before the date on which the Change in Control occurred (or if Employee was not employed for that entire five year period, then the mean average annual compensation paid to employee during such shorter period, with the Employee’s compensation annualized for any calendar year during which the employee was not employed for the entire calendar year); provided, however, that if the severance payment under this Section 5.8, either alone or together with any other payments or compensation which Employee has a right to receive from the Corporation, would constitute a “parachute payment” (as defined in Section 280G (or any equivalent term defined in any successor or equivalent provision) of the Code), then such severance payment shall be reduced to the largest amount as will result in no portion of the severance payment under this Section 5.8 being subject to the excise tax imposed by Section 4999 (or any successor or equivalent provision) of the Code. For the purpose of this Section 5.8, the Employee’s annual compensation from the Corporation and its subsidiaries for a given year shall equal Employee’s compensation as reflected on Employee’s Form W-2 for that year (unless the Employee was not employed for the entire calendar year, in which case Employee’s Form W-2 compensation for such year shall be annualized). The determination of any reduction in severance payment under this Section 5.8 pursuant to the foregoing provision shall be conclusive and binding on the Corporation.

If the Change in Control implicated by this Section 5.8 is also a “change in control event” within the meaning of the default rules of the final regulations promulgated under Section 409A(a)(2)(A)(v) of the Code, then the severance payment due under this Section 5.8 shall be made in a lump sum, payable no later than the 15th day of the third month following the later of the end of the Corporation’s tax year or the Employee’s tax year in which occurs the Employee’s effective date of termination under this Section 5.8. If the Change in Control is not a “change in control event” within the meaning of the default rules of the final regulations promulgated under Section 409A(a)(2)(A)(v) of the Code, the severance payment contemplated by this Section 5.8 shall be made in twelve semi-monthly installment payments, beginning on the first regularly scheduled payroll date following the Employee’s effective date of termination under this Section 5.8. For purposes of this Section 5.8, the Employee’s effective date of termination shall mean, as applicable, (x) the effective date of such termination of employment by the Corporation or (y) the effective date of the Employee’s resignation for Good Reason, which date shall be stated in the Employee’s written notice to the Corporation of his resignation for Good Reason and shall be no later than 60 days following the date of such notice.

“Good Reason” shall mean any of the following which occur during the term of this Agreement without Employee’s express written consent:

In the Event of a Change in Control:

(a) the assignment to Employee of duties inconsistent with Employee’s position, office, duties, responsibilities and status with the Corporation immediately prior to a Change in Control; or, a change in Employee’s titles or offices as in effect immediately prior to a Change in Control; or, any removal of Employee from or any failure to reelect Employee to any such position or office, except in connection with the termination of Employee’s employment by the Corporation for Disability or Cause or as a result of Employee’s death or by Employee other than for Good Reason as set forth in this Section 5.8(a); or

5

(b) a reduction by the Corporation in Employee’s Salary as in effect as of the date of this Agreement or as the same may be increased from time-to-time during the term of this Agreement or the Corporation’s failure to increase (within twelve months of the Employee’s last increase in Salary) Employee’s Salary after a Change in Control in an amount which at least equals, on a percentage basis, the highest percentage increase in salary for all officers of the Corporation or any parent or affiliated company effected in the preceding twelve months; or

(c) the failure of the Corporation to provide Employee with the same fringe benefits (including, without limitation, life insurance plans, medical or disability plans, retirement plans, incentive plans, stock option plans, stock purchase plans, stock ownership plans, or bonus plans) that were provided to Employee immediately prior to the Change in Control, or with a package of fringe benefits that, if one or more of such benefits varies from those in effect immediately prior to such Change in Control, is in Employee’s sole judgment substantially comparable in all material respects to such fringe benefits taken as a whole; or

(d) relocation of the Corporation’s principal executive offices to a location outside of Oklahoma City, Oklahoma, or Employee’s relocation to any place other than the location at which Employee performed Employee’s duties prior to a Change in Control, except for required travel by Employee on the Corporation’s business to an extent substantially consistent with Employee’s business travel obligations at the time of the Change in Control; or

(e) any failure by the Corporation to provide Employee with the same number of paid vacation days to which Employee is entitled at the time of the Change in Control; or

(f) the failure of a successor to the Corporation to assume the obligation of this Agreement as set forth in Section 7.1 herein.

5.9 Change in Control. For the purposes of this Agreement, the phrase “change in control” shall mean any of the following events:

(a) Any consolidation or merger of the Corporation in which the Corporation is not the continuing or surviving corporation or pursuant to which shares of the Corporation’s capital stock would convert into cash, securities or other property, other than a merger of the Corporation in which the holders of the Corporation’s capital stock immediately prior to the merger have the same proportionate ownership of capital stock of the surviving corporation immediately after the merger;

(b) Any sale, lease, exchange or other transfer (whether in one transaction or a series of related transactions) of all or substantially all of the assets of the Corporation;

(c) The stockholders of the Corporation approve any plan or proposal for the liquidation or dissolution of the Corporation;

(d) Any person (as used in Section 13(d) and 14(d)(2) of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”)) becomes the beneficial owner (within the meaning of Rule 13D-3 under the Exchange Act) of 50% or more of the Corporation’s outstanding capital stock;

6

(e) During any period of two consecutive years, individuals who at the beginning of that period constitute the entire Board of Directors of the Corporation cease for any reason to constitute a majority of the Board of Directors unless the election or the nomination for election by the Corporation’s stockholders of each new director received the approval of the Board of Directors by a vote of at least two-thirds of the directors then and still in office and who served as directors at the beginning of the period; or

(f) The Corporation becomes a subsidiary of any other corporation.

5.10 Agreement and Release. Notwithstanding any provision of this Agreement to the contrary, the obligation of the Corporation to pay any compensation upon separation from service or severance benefits to the Employee in accordance with this Article V is expressly conditioned upon the Employee’s timely execution of an agreement by the Employee to (a) comply with the terms and conditions of Article VIII below and (b) be bound by a release of any and all claims arising out of or relating to the Employee’s employment and termination of employment (a “Release”), that is or becomes irrevocable not later than the date the first (or only) payment is due pursuant to this Article V (the “Payment Date”). The Corporation shall have no obligation to pay any compensation upon separation from service or severance benefits to the Employee if the Employee fails to execute a Release that is or becomes irrevocable after the Payment Date. Such Release shall be made in a form satisfactory to the Corporation, substantially in the form set forth in Annex A hereto, and shall be for the benefit of the Corporation, its respective affiliates, and their respective officers, employees, directors, shareholders, agents, successors and assigns.

ARTICLE VI

Obligation to Mitigate Damages; No Effect

on Other Contractual Rights

6.1 Mitigation. The Employee shall not have any obligation to mitigate damages or the amount of any payment provided for under this Agreement by seeking other employment or otherwise. However, all payments required under the terms of this Agreement shall cease 30 days after the acceptance by the Employee of employment by another employer; provided that, this limitation shall not apply to payments due under paragraph 5.8, above.

6.2 Other Contractual Rights. The provisions of this Agreement, and any payment provided for hereunder shall not reduce any amount otherwise payable, or in any way diminish Employee’s existing rights, or rights which would accrue solely as a result of passage of time under any employee benefit plan or other contract, plan or arrangement of which Employee is a beneficiary or in which Employee participates.

ARTICLE VII

Successors to the Corporation

7.1 Assumption. The Corporation will require any successor or assignee (whether direct or indirect, by purchase, merger, consolidation or otherwise) of all or substantially all of the business and/or assets of the Corporation, by agreement in form and substance reasonably satisfactory to Employee, to expressly, absolutely and unconditionally assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform it if no

7

such succession or assignment had taken place. Any failure by the Corporation to obtain such agreement prior to the effectiveness of any such succession or assignment shall be a material breach of this Agreement.

7.2 Employee’s Successors and Assigns. This Agreement shall inure to the benefit of and be enforceable by Employee’s personal and legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If Employee should die while any amounts are still payable to Employee hereunder, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to Employee’s devisee, legatee or other designee or, if there is no such designee, to Employee’s estate.

ARTICLE VIII

8.2 Restrictive Covenant. During the term of Employee’s employment, the Employee shall not retain in or have any interest, directly or indirectly, in any business competing with the business being conducted by the Corporation or any of its subsidiaries, without the Corporation’s prior written consent. For the six month period immediately following the termination of Employee’s employment, the Employee shall not engage in or have any interest, directly or indirectly, in any fast food restaurant business that has a menu similar to that of a Sonic drive-in restaurant (such as hamburgers, hot dogs, onion rings and similar items customarily sold by Sonic drive-in restaurants), or which has an appearance similar to that of a Sonic drive-in restaurant (such as color pattern, use of canopies, use of speakers and menu housings for ordering food, or other items that are customarily used by a Sonic drive-in restaurant), and which operates such restaurants within a three mile radius of any Sonic drive-in restaurant.

FORM OF RELEASE

In connection with my separation from service with Sonic Corp. (“Sonic”), I provide the following Release of Claims (the “Release”).

I. General Release.

I, and each of my respective heirs, executors, administrators, representatives, agents, successors and assigns (collectively, the “Releasors”) hereby irrevocably and unconditionally release and forever discharge Sonic, its subsidiaries and affiliates (the “Company Group”) and each of their respective officers, employees, directors, shareholders, agents, successors and assigns from any and all claims, actions, causes of action, rights, judgments, obligations, damages, demands, accountings or liabilities of whatever kind or character (collectively, “Claims”), including, without limitation, any Claims under any federal, state, local or foreign law, that the Releasors may have, or in the future may possess, arising out of (i) my employment relationship with and service as an employee or officer of the Company Group, and the termination of such relationship or service, or (ii) any event, condition, circumstance or obligation that occurred, existed or arose on or prior to the date hereof; provided, however, that this Release shall not apply to any claims by me for benefits to which I am entitled as of the date of this Release under Sonic’s compensation and benefit plans, subject, in each case, to the applicable terms and conditions of each such plan. Without limiting the scope of the foregoing provision in any way, I hereby release all claims relating to or arising out of any aspect of my employment with the Company Group, including but not limited to, all claims under Title VII of the Civil Rights Act, the Civil Rights Act of 1991 and the laws amended thereby; the Age Discrimination in Employment Act of 1967; the Older Workers Benefit Protection Act of 1990; the Americans with Disabilities Act; the Family and Medical Leave Act of 1993; the Fair Labor Standards Act of 1963; any contract of employment, express or implied; any provision of the Constitution of the United States or of any particular State; and any other law, common or statutory, of the United States, or any particular State; any claim for the negligent and/or intentional infliction of emotional distress or specific intent to harm; any claims for attorneys fees, costs and/or expenses; any claims for unpaid or withheld wages, severance pay, benefits, bonuses, commissions and/or other compensation of any kind; and/or any other federal, state or local human rights, civil rights, wage and hour, wage payment, pension or labor laws, rules and/or regulations; all claims growing out of any legal restrictions on the Company Group’s right to hire and/or terminate its employees, including all claims that were asserted and/or that could have been asserted by me and all claims for breach of promise, public policy, negligence, retaliation, defamation, impairment of economic opportunity, loss of business opportunity, fraud, misrepresentation, etc. The Releasors further agree that the payments and benefits described in the Employee’s Employment Agreement dated                     , 20         (the “Employment Agreement”), shall be in full satisfaction of any and all Claims for payments or benefits, whether express or implied, that the Releasors may have against the Company Group arising out of my employment relationship or my service as an employee or officer of the Company Group and the termination thereof.

In consideration for, among other things, certain actions by Sonic in support of my separation from service, the Releasors hereby unconditionally release and forever discharge the Company Group from any and all Claims arising under the Federal Age Discrimination in Employment Act of 1967, as amended, and the applicable rules and regulations promulgated thereunder (“ADEA”)
