You have expressed a desire to transition your service to Dunkin’ Brands, Inc., a Delaware corporation (the “Company”) and its parent, Dunkin’ Brands Group Holdings, Inc., a Delaware corporation (“Holdings”), to a non-executive role as Chairman of the Board of Directors of the Company and Holdings (the “Board”). Both the Company and Holdings agree that this modification of your services will continue to allow the Company and Holdings to utilize and benefit from your experience and expertise.

You, the Company and Holdings have agreed that following midnight local time on the date hereof, June 30, 2010 (the “Transition Date”), you will continue to serve the Company and Holdings as a director and as (non-executive) Chairman of the Board on the terms set forth herein. The purpose of this letter agreement (the “Agreement”) is to confirm the arrangements between and among you, the Company and Holdings concerning the terms of your continued relationship with the Company and Holdings following the Transition Date, as follows:

1. Transition Period. Until the Transition Date, your service as the Chairman of the Board shall continue to be governed by the terms contained in the Amended and Restated Executive Employment Agreement made and entered into by you, the Company and Holdings effective as of December 31, 2008, and as further amended as of January 6, 2009, (the “Employment Agreement”). Your right to receive the benefits under this Agreement is expressly conditioned upon your continued compliance with your obligations under the Employment Agreement through the Transition Date; provided, that Section 5(e) of the Employment Agreement shall be of no further force and effect, effective immediately. Immediately following the Transition Date, the Employment Agreement shall be of no further force and effect (except as expressly provided herein) and your continued relationship with the Company shall be governed by the terms of this Agreement.

2. Resignation.

(a) As of the Transition Date, you hereby resign your employment with the Company and Holdings and all other positions, offices and directorships with the Company and Holdings, save only your position as a director and as Chairman of the Board. This resignation is irrevocable, effective immediately. You acknowledge and

1

agree that you will not be entitled to any severance or termination pay or benefits under Section 5 of the Employment Agreement in respect of or related to such resignation.

(b) On the next regular pay date for executives of the Company following the Transition Date, the Company will pay you: (i) your base salary earned through the Transition Date and (ii) pay, at the rate of your base salary, for the number of days of vacation you have earned but not used as of the Transition Date.

(c) Subject to your compliance with Section 2(e) below, the Company will pay you (i) $250,000 in respect of the fiscal year 2009 incentive bonus and (ii) in a lump sum the gross amount of $1,750,000. Such payments will be made on the 30th day following the Transition Date.

(d) Your existing deferred compensation balance of $754,997.59 will be paid out in accordance with the terms of the existing deferral arrangement upon your separation from service as defined in Section 1.409A-1(h) of the Treasury regulations.

(e) Within 21 days of the Transition Date, you, Holdings and the Company will execute the Release Agreements attached hereto as Exhibit A and B. Your right to receive the compensation and benefits provided under this Agreement (other than those provided under Section 2(b) hereof) are expressly conditioned on your signing and not revoking such Release Agreement prior to the payment date.

3. Continued Service as a Director and as Chairman. During the period commencing on the Transition Date and ending upon the termination of your service pursuant to Section 11 hereof (such period, the “Term”), you will serve Holdings and the Company as a director and as (non-executive) Chairman of the Board. During the Term, you will perform those duties and functions customarily performed by a non-executive chairman of a board of directors. In addition, and with no additional compensation, you shall perform services on behalf of Holdings and the Company on projects mutually agreed upon by you and the Board from time to time. Holdings and the Company acknowledge that you will be based out of your home office located in Florida; provided, that you may be required to travel to the Company’s headquarters in Canton, Massachusetts and elsewhere, from time to time, as reasonably required to perform your duties hereunder.

4. Compensation. During the Term, as full compensation for all services performed by you on behalf of Holdings and the Company, the Company will provide you the following compensation:

(a) The Company will pay you an outside director’s fee at the rate of $50,000 per annum for such time as you serve as a director (including as Chairman) (the “Board Fee”). The Board Fee shall be payable quarterly in arrears, with the first payment due on September 30, 2010.

(b) The Company will pay you a per annum chairman fee in the amounts set forth below during your continued service as Chairman (the “Chairman Fee”).

(c) You agree to enroll and to cause your wife to enroll in Medicare Part B coverage as soon as practicable after the date hereof. During the Final Term, following such enrollment in Medicare Part B coverage, the Company will reimburse you for the full premium cost of a Medicare supplemental insurance policy for you and your wife through the Blue Cross Blue Shield of Florida Blue Medicare PPO (“Blue Cross Medicare”)(or equivalent coverage through another provider that has a monthly premium cost that is no greater than the Blue Cross Medicare). At the end of the Final Term, to the extent that you seek other Medicare supplemental insurance, the Company will use commercially reasonable efforts to assist you in ensuring that such transition will not cause a disruption of coverage due to limitations on preexisting conditions, provided that you will be responsible for paying all premiums and for taking all actions reasonably required to obtain or continue such coverage following the end of the Final Term.

(d) During the Final Term, the Company shall reimburse you for the following insurance costs, provided that you have taken all actions reasonably necessary to enroll in the applicable benefit coverage: (1) monthly premium cost of dental insurance, with coverage as comparable as possible to the dental insurance provided during your employment; (2) premium cost of basic term life insurance in the face amount of $520,000 through the Hartford Insurance Company, pursuant to conversion coverage under the Company’s group term life insurance plan; (3) premium cost of Executive Life Insurance through Security Connecticut in the face amount of $1,000,000; (4) $50,000 per year in respect of the annual premium on the policy of whole life insurance heretofore provided to you pursuant to Section 4(e) of the Employment Agreement (the “Whole Life Policy”). Such payments shall be made quarterly in arrears, with the first such payment due on September 30, 2010. The life insurance trust that you have established shall continue to be the owner of the Whole Life Policy.

(e) The Company shall pay or reimburse you for all reasonable business expenses incurred or paid by you in the performance of your duties hereunder during the Term, upon submission of documentation in accordance with the Company’s then regular procedures for substantiation of expenses. Any reimbursement under this Agreement that would constitute nonqualified deferred compensation subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall be subject to the following additional rules: (i) no reimbursement of any such expense shall affect your right to reimbursement of any such expense in any other taxable year; (ii) reimbursement of the expense shall be made, if at all, promptly, but not later than the end of the calendar year following the calendar year in which the expense was incurred; and (iii) the right to reimbursement shall not be subject to liquidation or exchange for any other benefit.

(f) The Company shall provide you with adequate administrative support consistent with your then-current role as a director and/or as Chairman.

You will comply with the policies and procedures of the Company and its Affiliates for protecting Confidential Information and will not disclose to any Person or use, other than as required by applicable law or for the proper performance of your duties and responsibilities to the Company and its Affiliates, any Confidential Information obtained by you incident to your prior employment, your service or your association with the Company or any of its Affiliates, provided that you may divulge any Confidential Information that may be required by law and may disclose such information to your personal advisors for purposes of enforcing or interpreting this Agreement. You understand that this restriction shall continue to apply after your service hereunder terminates, regardless of the reason for such termination. The confidentiality obligation under this Section 13 shall not apply to information which is generally known or readily available to the public at the time of disclosure or becomes generally known through no wrongful act on the part of you or any other Person having an obligation of confidentiality to the Company or any of its Affiliates. Following termination of your service hereunder, you will not communicate or divulge any Confidential Information without the Company’s prior written consent or as may otherwise be required by law or legal process.

You will surrender to the Company at the time your service hereunder terminates all property of the Company, including without limitation all Documents containing Confidential Information then in your possession.

(c) You will not disclose to or use on behalf of the Company any proprietary information of a third party without such party’s consent.

14. Assignment of Rights to Intellectual Property.

Subject to the foregoing, you agree to execute any and all applications for domestic and foreign patents, copyrights or other proprietary rights and to do such other acts requested by the Company to assign the Intellectual Property so developed to the Company and to permit the Company to enforce any patents, copyrights or other proprietary rights to the Intellectual Property. All copyrightable works that you create will be considered “work made for hire” and will, upon creation, be owned exclusively by the Company.

15. Restricted Activities. You agree that some restrictions on your activities during and after your service hereunder are necessary to protect the good will, Confidential Information and other legitimate interests of the Company and its Affiliates:

7

(a) While you serve as either a director or as Chairman of the Board, and for two (2) years after the date on which your service in both positions has terminated (the “Restricted Period”), without the prior written consent of the Board you will not, directly or indirectly, whether as owner, partner, investor, consultant, agent, employee, co-venturer or otherwise, compete with the Company or any of its Affiliates or undertake any planning for any business competitive with the Company or any of its Affiliates. Specifically, but without limiting the foregoing, without the prior written consent of the Board you agree not to engage in any manner in any activity that is directly or indirectly competitive with the business of the Company or any of its Affiliates as conducted during prior to the date hereof and during your employment or during the Term and further agree not to work or provide services, in any capacity, whether as an employee, independent contractor or otherwise, whether with or without compensation, to any Person who is engaged in any business that is competitive with the business of the Company or any of its Affiliates for which you have provided services. Restricted activity includes without limitation accepting employment with any Person who is, or at any time within one year prior to termination of your services hereunder has been, a franchisee of the Company or any of its Affiliates. For the purposes of this Section 15, the business of the Company and its Affiliates shall include all Products and your undertaking shall encompass all items, products and services that may be used in substitution for Products. The foregoing, however, shall not prevent your passive ownership of two percent (2%) or less of the equity securities of any publicly traded company.

(b) You agree that, during the Restricted Period, without the prior written consent of the Board you will not directly or indirectly (a) solicit or encourage any franchisee of the Company or any of its Affiliates to terminate or diminish its relationship with them; or (b) seek to persuade any such franchisee or prospective franchisee of the Company or any of its Affiliates to conduct with anyone else any business or activity which such franchisee or prospective franchisee conducts with the Company or any of its Affiliates; provided that these restrictions shall apply (y) only with respect to those Persons who are or have been a franchisee of the Company or any of its Affiliates at any time within the immediately preceding one year or whose business has been solicited on behalf of the Company or any of the Affiliates by any of their officers, employees or agents (and of which you have actual knowledge) within said one year period, other than by form letter, blanket mailing or published advertisement, and (z) only if you have performed work for such Person during your employment with the Company or one of its Affiliates or been introduced to such Person as a result of your employment or other associations with the Company or one of its Affiliates.

(c) You agree that during the Restricted Period, without the prior written consent of the Board you will not, and will not assist any other Person to, (a) hire or solicit for hiring any employee of the Company or any of its Affiliates as of the date of such solicitation or was employed by the Company or any of its Affiliates during the six (6) months prior to your termination of employment, or seek to persuade any employee of the Company or any of its Affiliates to discontinue employment or (b) solicit or encourage any independent contractor providing services to the Company or any of its Affiliates to terminate or diminish its relationship with them. For the purposes of this Agreement, an “employee” of the Company or any of its Affiliates is any person who was such at any time within the preceding year. For purposes hereof, general solicitations not

8

directed at a particular person or advertising in media directed at the general public shall not provide the basis for a claim by the Company that you violated this Section.

16. Enforcement of Covenants. You acknowledge that you have carefully read and considered all the terms and conditions of this Agreement, including the restraints imposed upon you pursuant to Sections 13, 14 and 15 hereof. You agree without reservation that each of the restraints contained herein is necessary for the reasonable and proper protection of the goodwill, Confidential Information and other legitimate interests of the Company and its Affiliates; that each and every one of those restraints is reasonable in respect to subject matter, length of time and geographic area; and that these restraints, individually or in the aggregate, will not prevent you from obtaining other suitable employment during the period in which you are bound by these restraints. You further acknowledge that, were you to breach any of the covenants contained in Sections 13, 14 or 15 hereof, the damage to the Company would be irreparable. You therefore agree that the Company, in addition to any other remedies available to it, will be entitled to preliminary and permanent injunctive relief against any breach or threatened breach by you of any of said covenants, without having to post bond, as well as to its reasonable attorneys’ fees and costs incurred in connection with such breach. The parties further agree that, in the event that any provision of Section 13, 14 or 15 hereof shall be determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, such provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law.

17. Definitions. Words or phrases which are initially capitalized or are within quotation marks shall have the meanings provided in this Section and as provided elsewhere herein. For purposes of this Agreement, the following definitions apply:

Within thirty (30) days of the notice of the Company of Cause and prior to any such termination, you shall be given an opportunity to make a presentation to the Board (accompanied by counsel or other representative if so desired) at a meeting of the Board. Following such meeting the Board shall determine whether to terminate your services and shall notify you of its determination. For purposes of this definition, no act or failure to act on your part shall be considered “willful” unless it is done, or omitted to be done, by you in bad faith or without reasonable belief that your action or omission is in the bests interests of the Company. Any act or failure to act that is based upon authority given by a resolution duly adopted by the Board or based upon the advice of counsel for the Company, shall be conclusively presumed to be done, or omitted to be done, by you in good faith and in the best interests of the Company.
