 Dear Christiane:

 This Director Offer Letter
sets forth the terms and conditions of your appointment to serve as a director (“ Director ”) on the board of directors
(the “ Board ”) of Shake Shack Inc. (the “ Company ”) and to serve as a member of the Nominating &
Corporate Governance Committee of the Board (the “ Committee ”), effective as of July 2, 2026 (the “ Effective
Date ”).

 As a Director, you will be
expected to attend at least four (4) Board and four (4) Committee meetings each service year 1 and shall have such
other duties and responsibilities as are customarily associated with this position. You will serve on the Board until such time that
either you or the Company terminates your service or unless you are not re-elected to the Board at the Annual General Meeting of Stockholders
in June 2029.

 As consideration for your
service on the Board and the Committee, you will be eligible to receive annual cash compensation in the amount of Eighty Thousand Dollars
($80,000) and an annual equity award valued at One Hundred Forty Thousand Dollars ($140,000) each service year, totaling Two Hundred
Twenty Thousand Dollars ($220,000). You may elect (i) to receive additional equity in lieu of some or all of the cash portion of
your compensation and/or (ii) to defer the vesting of the equity portion of your compensation.

 Notwithstanding the above,
for the current service year, your (i) cash compensation will be Sixty Thousand Dollars ($60,000) and (ii) equity award value
will be One Hundred and Twenty-Eight Thousand and Three Hundred and Thirty-Three Dollars and Thirty-Three Cents ($128,333.33), which
reflects eleven-twelfths of the annual director equity award that is otherwise awarded in June.

 You will also be entitled
to coverage under the Company’s directors and officers liability insurance policy.

 During your tenure as a Director,
you will at all times and for all purposes be acting as an independent contractor and not as an employee of the Company. Accordingly,
you will not be eligible to participate in employee benefit plans provided by the Company to its employees and the Company will not,
on your account, (i) pay any unemployment tax or other taxes required under the law to be paid with respect to employees or (ii) withhold
any monies from any compensation paid to you for income or employment tax purposes. Director compensation is established by the Board
and so, notwithstanding this letter, it may be revised at any time and from time to time.

 Following your receipt of
this Director Offer Letter, you will receive from Ron Palmese, Chief Legal Officer, a number of documents to review and/or complete,
which are set forth in Schedule 1 hereto. You will also receive onboarding materials, which will include among other things, key dates
and board and management profiles. Mr. Palmese will be your primary contact in the weeks ahead; if you have any questions once you
receive them, please do not hesitate to reach out to him.

 Please confirm that the foregoing
reflects your understanding by signing and returning this letter to me, with a copy to Mr. Palmese. We are glad to have you aboard
and look forward to working together. Please feel free to contact me should you wish to discuss any aspect of your service on the Company’s
Board.

 Sincerely,

 /s/
 Daniel Meyer
