Mr. Mark L. Kleifges

14 Spruce Lane

Sudbury, MA 01776

Dear Mark:

You and The RMR Group LLC (“RMR”) are entering into this letter agreement (this “Agreement”) to confirm the terms and conditions of your retirement from RMR on June 30, 2019 (the “Retirement Date”).

A.Resignation from RMR. You will continue to serve as an Executive Vice President of RMR, Chief Financial Officer of Hospitality Properties Trust (“HPT”), a Managing Trustee and Chief Financial Officer of Government Properties Income Trust (“GOV”), and a Managing Trustee and Chief Financial Officer of the RMR Real Estate and Income Fund (“RIF”) and all other current offices of RMR, HPT, GOV, RIF and any of their affiliates until December 31, 2018 as of which date you will resign from all such offices and from any other officer and board positions you hold within RMR and any of its managed and affiliated companies (collectively, the “RMR Companies”). You will continue to serve as an employee of RMR until the Retirement Date in order to transition your duties and responsibilities to your successor(s).

B.Payments until the Retirement Date. Until December 31, 2018, you will continue to receive your same cash salary compensation and benefits as you currently receive. From January 1, 2019 until the Retirement Date, RMR will pay your base salary at a rate of $10,000 per month. Subject to any contribution required by you consistent with past practices, RMR will also maintain and provide all your current insurance and employee benefits until the Retirement Date.

C.Retirement and Transition Responsibilities. From January 1, 2019 until the Retirement Date, you will work towards the orderly transition of your responsibilities and use all reasonable efforts to assist in training your successor(s). It is understood that you may not come into the office every day or even regularly during this transition period.

D.Licensing. As soon as practicable after this Agreement is executed, RMR will take all reasonable steps and work with its managed companies to the best of its ability to remove you from any

gambling, liquor or other licenses. You agree to cooperate with all such efforts.

E.Payments and Benefits on the Retirement Date. On the Retirement Date, RMR will pay your unpaid wages for the period through the Retirement Date, subject to all usual and applicable taxes and deductions. Your health insurance on RMR’s group plan will terminate on the Retirement Date. To continue any health insurance beyond the Retirement Date, you must complete a continuation of coverage (COBRA) election form and make timely payments for coverage. Information regarding COBRA will be mailed to you. Any group life and disability insurance on our group plan will terminate on the Retirement Date, as will your participation in the RMR 401(k) plan.

F.Retirement Benefits. Provided you sign and do not revoke the Waivers and Releases of Claims attached as Exhibit A and Exhibit B and you satisfactorily perform your transition responsibilities, you will receive the following additional retirement payments and benefits:

(1)Cash Payments. RMR will pay you a lump sum payment of $1,593,750, subject to applicable deductions, no later than two business days after the expiration of the revocation period set forth in the Waiver and Release of Claims attached as Exhibit A and a second lump sum payment of $1,593,750, subject to applicable deductions, no later than two business days after the expiration of the revocation period set forth in the Waiver and Release of Claims attached as Exhibit B, which document will be provided to you again on the Retirement Date.

(2)RMR and RMR Company Share Grants.

a.Prior to the Retirement Date, RMR will recommend to the Boards of Directors and Boards of Trustees of The RMR Group Inc., GOV, HPT, Select Income REIT, Senior Housing Properties Trust, Industrial Logistics Properties Trust, TravelCenters of America LLC, Five Star Senior Living Inc. and Tremont Mortgage Trust (together, the “RMR Public Companies”) that all of your existing share grants vest (which vesting includes the lifting of any restrictions) immediately in full upon the Retirement Date and that you be permitted to settle any resulting tax liability with vesting shares, commonly referred to as “net share settlement,” on a company-by-company basis. RMR will cooperate with you in removing any restrictive legends from your vested shares in the RMR Public Companies.

b.You agree for the benefit of the applicable RMR Public Company that, as long as you own the shares referenced above in 2(a) in the RMR Public Companies, your shares shall be voted at any meeting of the shareholders of the RMR Public Companies or in connection with any consent solicitation or other action by shareholders in favor of all nominees for director and all proposals recommended by the Board of Directors or Trustees in the proxy statement for such meeting or materials for such written consent or other action. This obligation does not apply to your estate. If your shares are not voted in accordance with this covenant and such failure continues after notice, you agree to pay liquidated damages to the applicable RMR Public Company in an amount equal to the market value of the shares not so voted. For the avoidance of doubt, this provision is for the benefit of each RMR Public Company only with respect to your shares in such company and is not an agreement with RMR.

c.You understand and agree that, although the RMR Code of Business Conduct and Ethics will no longer apply to you after the Retirement Date, you are subject to all laws and regulations with respect to all of your shares in the RMR Public Companies, including, but not limited to, those applicable to the purchase or sale of securities while in possession of material, non-public information concerning the RMR Public Companies.

(3)Mobile Phone Number. RMR agrees to consent to and cooperate with you in the

transfer to you of the mobile phone number (No. 617 ###-###-####), and to pay for any costs associated with such transfer (except that you will be responsible for the cost of replacement equipment and service). You agree to be responsible for all cell phone payments for service after the Retirement Date.

You agree that you shall be responsible and will pay your own tax obligations and/or liabilities created under state or federal tax laws by this Agreement.

Adam Portnoy, RMR’s President and Chief Executive Officer, will send an email to all employees of RMR regarding your retirement, the timing and content of which shall be subject to your reasonable approval. Following the Retirement Date and provided you sign, return and do not revoke the Waiver and Release of Claims attached as Exhibit B, Mr. Portnoy will provide you with a letter of reference which shall be in form and substance mutually acceptable to you and Mr. Portnoy.

You agree that, unless otherwise agreed, on or before the Retirement Date, you will return to RMR all property of RMR including, but not limited, to all documents, records, materials, software, equipment, personal service devices, building keys or entry cards, and other physical property that have come into your possession or been produced by you in connection with your employment with RMR; it being agreed, however, that you may retain the iPhone issued to you by RMR. You agree that RMR may delete all information related to the RMR Companies from the iPhone immediately after the Retirement Date, unless we otherwise agree.

In addition, you shall not at any time reveal to any person or entity, except to employees of RMR who need to know such information for purposes of their employment or as otherwise authorized by RMR in writing, any confidential information of RMR or any RMR Company, including, but not limited to confidential information regarding (i) the marketing, business and financial activities and/or strategies of RMR or any RMR Company, (ii) the costs, sources of supply, financial performance, projects, plans, branding, acquisition or dispositions, proposals and strategic plans of RMR or any RMR Company, and (iii) information and discussions concerning any past or present lawsuits, arbitrations or other pending or threatened disputes in which RMR or any RMR Company is or was a party.

Nothing in this Agreement prohibits you from reporting possible violations of federal law or regulation to any government agency or entity, including, but not limited, to the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of applicable law. You do not need prior authorization of RMR to make any such reports or disclosures and you are not required to notify RMR that you have made such reports or disclosures.

You agree not to make harmful or disparaging remarks, written or oral, concerning RMR or any RMR Company, or any of its or their respective directors, officers, trustees, employees, agents or service providers. RMR agrees to instruct its executive officers not to make any harmful or disparaging remarks, written or oral, concerning you. Nothing in this provision shall prevent you or RMR from testifying truthfully in connection with any litigation, arbitration or administrative proceeding when compelled by

subpoena, regulation or court order.

You agree that for five (5) years following the Retirement Date, you will not, directly or indirectly, without the prior written consent of RMR, solicit, attempt to solicit, assist others to solicit, hire, or assist others to hire for employment any person who is, or within the preceding six (6) months was, an employee of RMR or any RMR Company.

The parties agree that any material breach of Sections IV, V or VI of this Agreement will cause irreparable damage to the non-breaching party and that, in the event of such a material breach or threatened material breach, the non-breaching party shall have, in addition to any and all remedies at law, the right to an injunction, specific performance or other equitable relief to prevent the violation of any obligations hereunder. The parties agree that, in the event that any provision of Section IV, V, or VI shall be determined by any court of competent jurisdiction or arbitration panel to be unenforceable, such provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law.

After the Retirement Date and until December 31, 2019, upon the request of RMR, you agree to make yourself reasonably available to provide any additional transitional services at a rate of $250 per hour, plus reimbursement of any approved out-of-pocket expenses. Any such services shall be deemed a consultancy and you shall perform such services as an independent contractor, assuming all applicable tax obligations. You acknowledge that as an independent contractor you will not be eligible for any benefits afforded employees of RMR and any RMR Company.

Without limitation as to time, you further agree to cooperate with RMR and any RMR Company, at reasonable times and places, with respect to all matters arising during or related to your continuing or past employment, including but not limited to all formal or informal matters in connection with any government investigation, internal investigation, litigation, regulatory or other proceeding which may have arisen or which may arise. RMR or such RMR Company will reimburse you for all reasonable out-of-pocket expenses (not including lost time or opportunity). RMR or such RMR Company will provide appropriate legal representation for you in a manner reasonably determined by RMR or such RMR Company.

Any and all indemnification agreements you have from RMR and any RMR Companies continue to provide for the respective parties’ rights and obligations with respect to the matters set forth therein. Further, you will maintain any rights you have to indemnification and defense under any bylaws or insurance policies by RMR as well as any rights you have under the common law.

Any waiver by a party of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach of such provision or any other provision hereof.

The parties agree and acknowledge that the considerations exchanged herein do not constitute and shall be not construed as constituting an admission of any sort on the part of either party.

The parties agree that this Agreement may not be used as evidence in any subsequent proceeding of any kind except one in which one of the parties alleges a breach of the terms of this Agreement or the Waivers and Releases of Claims or one in which one of the parties elects to use this Agreement as a defense to any claim.

This Agreement, together with the Waivers and Releases of Claims, constitutes the entire agreement between the parties concerning the terms and conditions of your separation of employment from RMR and supersedes all prior and contemporaneous agreements, understandings, negotiations, and discussions, whether oral or written, between the parties, except for any indemnification agreements as noted above, any applicable equity agreements and the Mutual Agreement to Resolve Disputes and Arbitrate Claims effective April 16, 2012, all of which remain in full force and effect. You agree that RMR has not made any warranties, representations, or promises to you regarding the meaning or implication of any provision of this Agreement other than as stated herein.

Any amendments to this Agreement shall be in writing and signed by you and an authorized representative of RMR.

In the event that any provision hereof becomes or is declared by a court of competent jurisdiction or an arbitrator or arbitration panel to be illegal, unenforceable, or void, this Agreement shall continue in full force and effect without said provision.

This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts without reference to any conflict of law principles, and shall be binding upon and inure to the benefit of you and your heirs, successors, and beneficiaries, and RMR and its agents, affiliates, representatives, successors, and assigns. If you die before receiving the payments stated herein, the remaining payments will be made to your spouse. If your spouse is not alive at the time, the remaining payments will be made to your estate.

The parties irrevocably agree that any dispute regarding this Agreement shall be settled by binding arbitration in accordance with the Mutual Agreement to Resolve Disputes and Arbitrate Claims.

XVII.    VOLUNTARY ACT
