Omnibus Incentive Plan

Option Agreement

(Nonstatutory Stock Option)

Pursuant to the accompanying Option Grant Notice (the “Grant Notice”) and this Option Agreement (the “Agreement”), Jack in the Box Inc. (the “Company”) has granted you an Option under the Jack in the Box Inc. 2023 Omnibus Incentive Plan (the “Plan”) to purchase the number of shares of Common Stock set forth in the Grant Notice at the exercise price set forth in the Grant Notice. This Option is granted to you effective as of the date of grant set forth in the Grant Notice (the “Date of Grant”). Capitalized terms not explicitly defined in this Agreement but defined in the Plan or the Grant Notice will have the same definitions as in the Plan or the Grant Notice.

1. Vesting.

(a) General. Subject to the limitations contained herein, this Option will vest, if at all, in accordance with the vesting schedule set forth in the Grant Notice, provided that vesting will cease upon the termination of your Continuous Service, except as provided in Section (b) or (c) below.

(b) Death. If prior to the date the Option vests in full, your Continuous Service ceases due to your death, then (i) all then-outstanding and unvested Options will remain outstanding and eligible to vest for the earlier of (1) 30 days following your death and (2) such date on which the Option would otherwise terminate pursuant to the Plan (e.g., upon a Change in Control) and (ii) all then-outstanding and vested Options will remain outstanding as set forth in Section 7(d) below.

(c) Retirement. If prior to the date that the Option vests in full, your Continuous Service ceases due to your Retirement, then all then-outstanding and unvested Options shall become 100% vested and exercisable on the date of such termination of Continuous Service. For purposes of this Agreement: “Retirement” means your termination of employment for any reason, other than “for cause” (as determined by the Board in its sole discretion), on or after age 62 with five or more full years of Continuous Service. Accelerated vesting in accordance with the foregoing will only occur if your termination of Continuous Service is also a “separation from service” within the meaning of Treasury Regulations Section 1.409A-1(h), without regard to any alternative definition thereunder (a “Separation from Service”).

(d) Change in Control. Upon a Change in Control, the Options shall be treated as described in Section 9(c) of the Plan. If the Options are assumed, continued or substituted for in such Change in Control pursuant to Section 9(c)(i) of the Plan, the Options, to

3.

the extent not vested, shall become 100% vested and exercisable upon your Qualifying Termination.

(i) For purposes of this Agreement, a “Qualifying Termination” means your Separation from Service as a result of the occurrence of any of the following events during the twenty-four (24)-month period following a Change in Control: (1) the Company’s involuntary termination of your employment without Cause; or (2) your voluntary termination of employment for Good Reason. A Qualifying Termination shall not include a termination of your employment by reason of your death or Disability.

(ii) For purposes of this Agreement, “Good Reason” shall have the meaning ascribed to such term in any written agreement between you and the Company defining such term and, in the absence of such agreement, such term means, without your express written consent, your resignation of employment with the Company upon the occurrence of any one or more of the following conditions, provided that you first provide the Company with written notice of the existence of the applicable condition described in clauses (1) through (5) below no later than ninety (90) days after the initial existence of such condition is known by you and the Company fails to remedy such condition within 30 days of the date of such written notice:

(1) a material diminution in your authorities, duties or responsibilities, which shall include a material reduction or alteration in the nature or status of your authorities, duties or responsibilities from those in effect as of ninety (90) calendar days prior to the Change in Control, other than an insubstantial and inadvertent act that is remedied by the Company promptly after receipt of your notice given thereof;

(2) a requirement by the Company that you be based at a location in excess of fifty (50) miles from the location of your principal job location or office immediately prior to the Change in Control; except for required travel on the Company’s business to an extent consistent with your then present business travel obligations;

(3) a materialreduction by the Company to your base salary, excluding amounts (i) designated by the Company as payment toward reimbursement of expenses; or (ii) received under incentive or other bonus plans, regardless of whether or not the amounts are deferred;

(4) a material reduction inthe Company’s compensation, health and welfare benefits, retirement benefits, or perquisite programs under which you receive value, as such programs exist immediately prior to the Change in Control (however, the replacement of an existing program with a new program will be permissible (and not grounds for a Good Reason termination) if there is not a material reduction in the value to you under the new program); or

(5) any material breach by the Company of its obligations under this Agreement or under any other written agreement under which you provide services to the Company or the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company), as applicable.

3. Exercise Restriction for Non-Exempt Employees. In the event that you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (i.e., a “Non-Exempt Employee”), then except as otherwise provided in the Plan, you may not exercise this Option until you have completed at least six (6) months of Continuous Service following the Date of Grant, even if you have already been an Employee for more than six months.

4. Method of Payment. You must pay the full amount of the exercise price for the shares of Common Stock you wish to purchase. You may pay the exercise price through a cashless exercise, sell-to-cover or same-day-sale as permitted by the Grant Notice.

5. Whole Shares. You may exercise this Option only for whole shares of Common Stock.

6. Securities Law Compliance.

If the reduction of the Payments would not result in a greater after-tax result to you (taking into account the Excise Tax as well as applicable federal, state and local income and employment taxes), then no Payments shall be reduced pursuant to this provision.

deferred compensation plan; (E) fifth, outstanding performance-based equity grants; and (F) finally, any time-vesting equity grants. In each case, Payments will be reduced beginning with Payments that would be made last in time.

(c) All determinations required to be made under this Section 21 shall be made by the public accounting firm that is retained by the Company or such other nationally recognized public accounting firm appointed by the Company (the “Accounting Firm”). The Accounting Firm shall provide detailed supporting calculations both to you and the Company within fifteen (15) business days of the receipt of notice from you or the Company that there has been a Payment, or such earlier time as is requested by the Company. All fees, costs and expenses (including, but not limited to, the costs of retaining experts) of the Accounting Firm shall be borne by the Company. The determination by the Accounting Firm shall be binding upon you and the Company.

22. Miscellaneous.

(a) The rights and obligations of the Company under this Option will be transferable to any one or more persons or entities, and all covenants and agreements hereunder will inure to the benefit of, and be enforceable by, the Company’s successors and assigns.

(b) You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the Company to carry out the purposes or intent of this Option.
