We have no employees. The personnel and various services we require to operate our business are provided to us by RMR. We have two agreements with RMR to provide management services to us: (1) a business management agreement, which relates to our business generally; and (2) a property management agreement, which relates to the property level operations of many of our properties, including our medical office and life science properties, and major renovation or repositioning activities at our senior living communities that we may request RMR to manage from time to time. See Note 8 for further information regarding our relationship, agreements and transactions with RMR.

Management Agreements with RMR. Our management agreements with RMR provide for an annual base management fee, an annual incentive management fee and property management and construction supervision fees, payable in cash, among other terms:

◦the sum of (a) 0.5% of the daily weighted average of the aggregate book value of our real estate assets owned by us or our subsidiaries as of October 12, 1999, or the Transferred Assets, plus (b) 0.7% of the average aggregate historical cost of our real estate investments excluding the Transferred Assets up to $250,000, plus (c) 0.5% of the average aggregate historical cost of our real estate investments excluding the Transferred Assets exceeding $250,000; and

◦the sum of (a) 0.7% of the average closing price per share of our common shares on the stock exchange on which such shares are principally traded during such period, multiplied by the average number of our common shares outstanding during such period, plus the daily weighted average of the aggregate liquidation preference of each class of our preferred shares outstanding during such period, plus the daily weighted average of the aggregate principal amount of our consolidated indebtedness during such period, or, together, our Average Market Capitalization, up to $250,000, plus (b) 0.5% of our Average Market Capitalization exceeding $250,000.

The average aggregate historical cost of our real estate investments includes our consolidated assets invested, directly or indirectly, in equity interests in or loans secured by real estate and personal property owned in connection with such real estate (including acquisition related costs and costs which may be allocated to intangibles or are unallocated), all before reserves for depreciation, amortization, impairment charges or bad debts or other similar non-cash reserves.

◦the amount (expressed as a percentage) by which the total return per share, as defined in the business management agreement and further described below, of our common shareholders (i.e., share price appreciation plus dividends) exceeds the total shareholder return of the applicable market index, or the benchmark return per share, for the relevant measurement period. The MSCI U.S. REIT/Health Care REIT Index is the applicable benchmark index.

For purposes of the total return per share of our common shareholders, share price appreciation for a measurement period is determined by subtracting (1) the closing price of our common shares on Nasdaq on the last trading day of the year immediately before the first year of the applicable measurement period, or the initial share price, from (2) the average closing price of our common shares on the 10 consecutive trading days having the highest average closing prices during the final 30 trading days in the last year of the measurement period.

◦The calculation of the incentive management fee (including the determinations of our equity market capitalization, initial share price and the total return per share of our common shareholders) is subject to adjustments if we issue or repurchase our common shares, or if our common shares are forfeited, during the measurement period.

◦If our total return per share exceeds 12.0% per year in any measurement period, the benchmark return per share is adjusted to be the lesser of the total shareholder return of the applicable market index for such measurement period and 12.0% per year, or the adjusted benchmark return per share. In instances where the adjusted benchmark return per share applies, the incentive management fee will be reduced if our total return per share is between 200 basis points and 500 basis points below the applicable market index in any year, by a low return factor, as defined in the business management agreement, and there will be no incentive management fee paid if, in these instances, our total return per share is more than 500 basis points below the applicable market index in any year, determined on a cumulative basis (i.e. between 200 basis points and 500 basis point per year multiplied by the number of years in the measurement period and below the applicable market index).

◦The incentive management fee is subject to a cap. The cap is equal to the value of the number of our common shares which would, after issuance, represent 1.5% of the number of our common shares then outstanding multiplied by the average closing price of our common shares during the 10 consecutive trading days having the highest average closing prices during the final 30 trading days of the relevant measurement period.

◦Incentive management fees we paid to RMR for any period may be subject to “clawback” if our consolidated financial statements for that period are restated due to material non-compliance with any financial reporting requirements under the securities laws as a result of the bad faith, fraud, willful misconduct or gross negligence of RMR and the amount of the incentive management fee we paid was greater than the amount we would have paid based on the restated consolidated financial statements.

•Property Management and Construction Supervision Fees. The property management fees payable to RMR by us for each applicable period are equal to 3.0% of gross collected rents and the construction supervision fees payable to RMR by us for each applicable period are equal to 5.0% of construction costs. Pursuant to our property management agreement with RMR, RMR provides oversight of any major capital projects and repositionings at our senior living communities, including our senior living communities which Five Star is continuing to manage, and RMR receives the same fee previously paid to Five Star for such services, which is equal to 3.0% of the cost of any such major capital project or repositioning.

•Expense Reimbursement. We are generally responsible for all our operating expenses, including certain expenses incurred or arranged by RMR on our behalf. We are generally not responsible for payment of RMR's employment, office or administrative expenses incurred to provide management services to us, except for the employment and related expenses of RMR's employees assigned to work exclusively or partly at our properties, our share of the wages, benefits and other related costs of RMR's centralized accounting personnel, our share of RMR's costs for providing our internal audit function, or as otherwise agreed. Our property level operating expenses are generally incorporated into the rents charged to our tenants, including certain payroll and related costs incurred by RMR.

•Term. Our management agreements with RMR have terms that end on December 31, 2044, and automatically extend on December 31st of each year for an additional year, so that the terms of our management agreements thereafter end on the 20th anniversary of the date of the extension.

•Termination Rights. We have the right to terminate one or both of our management agreements with RMR: (i) at any time on 60 days' written notice for convenience, (ii) immediately on written notice for cause, as defined therein, (iii) on written notice given within 60 days after the end of an applicable calendar year for a performance reason, as defined therein, and (iv) by written notice during the 12 months following a change of control of RMR, as defined therein. RMR has the right to terminate the management agreements for good reason, as defined therein.

•Termination Fee. If we terminate one or both of our management agreements with RMR for convenience, or if RMR terminates one or both of our management agreements for good reason, we have agreed to pay RMR a termination fee in an amount equal to the sum of the present values of the monthly future fees, as defined therein, for the terminated management agreement(s) for the term that was remaining prior to such termination, which, depending on the time of termination would be between 19 and 20 years. If we terminate one or both of our management agreements with RMR for a performance reason, we have agreed to pay RMR the termination fee calculated as described above, but assuming a 10 year term was remaining prior to the termination. We are not required to pay any termination fee if we terminate our management agreements with RMR for cause or as a result of a change of control of RMR.

•Transition Services. RMR has agreed to provide certain transition services to us for 120 days following an applicable termination by us or notice of termination by RMR, including cooperating with us and using commercially reasonable efforts to facilitate the orderly transfer of the management and real estate investment services provided under our business management agreement and to facilitate the orderly transfer of the management of the managed properties under our property management agreement, as applicable.

•Vendors. Pursuant to our management agreements with RMR, RMR may from time to time negotiate on our behalf with certain third party vendors and suppliers for the procurement of goods and services to us. As part of this arrangement, we may enter agreements with RMR and other companies to which RMR or its subsidiaries provide management services for the purpose of obtaining more favorable terms from such vendors and suppliers.

•Investment Opportunities. Under our business management agreement with RMR, we acknowledge that RMR may engage in other activities or businesses and act as the manager to any other person or entity (including other REITs) even though such person or entity has investment policies and objectives similar to ours and we are not entitled to preferential treatment in receiving information, recommendations and other services from RMR.

(1)The net business management fees we recognized for the years ended December 31, 2024, 2023 and 2022 reflect a reduction of $2,974 for each of those years for the amortization of the liability we recorded in connection with our former investment in RMR Inc.

(2)The net property management and construction supervision fees we recognized for the years ended December 31, 2024, 2023 and 2022 reflect a reduction of $797 for each of those years for the amortization of the liability we recorded in connection with our former investment in RMR Inc., as further described in Note 8.

In January 2025, in connection with a $100,000 credit agreement and related security agreement entered into by RMR and certain of its subsidiaries with Citibank, N.A., or Citibank, and the other lenders party thereto, we consented to the pledge and assignment of RMR’s interest in our management agreements under the security agreement. Pursuant to the consent, we agreed, among other things, that upon notice that an event of default under the RMR credit agreement has occurred and is continuing, we will continue to make all payments under our management agreements in accordance with the instructions of Citibank, and that if there is an event of default by RMR under our management agreements that would allow us to terminate or suspend our obligations, we will not terminate or suspend without notice to Citibank and provide Citibank 30 days to cure the default on RMR’s behalf. The consent was approved by our Independent Trustees.

Management Agreements between our Joint Ventures and RMR. We have two separate joint venture arrangements with third party institutional investors, the Seaport JV and the LSMD JV. RMR provides management services to both of these joint ventures. Our joint ventures are not our consolidated subsidiaries and, as a result, we are not obligated to pay management fees to RMR under our management agreements with RMR for the services it provides regarding the joint ventures. We wholly

owned the 10 medical office and life science properties included in the LSMD JV until the contribution of these properties to the LSMD JV in January 2022, and we paid management fees to RMR for the management services it provided to us for those properties until the contribution of those properties to the LSMD JV.
