(s)                                   Investment Purpose.  TRUST is acquiring the Subject REIT Shares for its own account and the account of its beneficiaries for investment purposes only and not with a view to the distribution or resale thereof, in whole or in part, and it will not transfer, or offer to transfer, all or any portion of the Subject REIT Shares in any manner that would violate or cause any of the RMR Parties to violate the Securities Act or any securities Laws of the several states.

Section 3.2                                    Representations and Warranties of REIT.  REIT hereby represents and warrants to the RMR Parties, subject to the exceptions set forth in the disclosure schedule prepared by REIT and delivered to the RMR Parties concurrently with the execution and delivery of this Agreement, that as of the date hereof as follows:

(c)                                  Authority; Validity of Agreement.  REIT has the requisite power, authority and legal right to execute and deliver this Agreement and each Transaction Document to which it is a party, and to consummate the transactions contemplated hereby and thereby, as the case may be.  This Agreement and each Transaction Document to which it is a party have been duly executed and delivered by REIT and constitute the legal, valid and binding obligations of REIT, enforceable against REIT in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar Laws relating to or affecting creditors’ rights generally.

(d)                                 No Conflicts.  The execution, delivery and performance by REIT of this Agreement and the Transaction Documents to which it is a party, the consummation by REIT of the transactions contemplated hereby or thereby and the compliance by REIT with the terms and provisions hereof or thereof, will not, directly or indirectly (with or without notice or lapse of time or both), (i) contravene or conflict with, or result in a breach or termination of, or constitute a default under (or with notice or lapse of time or both, result in the breach or termination of or constitute a default under) the organizational documents of REIT, (ii) constitute a violation by REIT of any existing requirement of Law applicable to REIT or any of its properties, rights or assets or (iii) require the consent or approval of any Person, except, in the case of clauses (ii) and (iii), as would not reasonably be expected to result in, individually or in the aggregate, a material adverse effect on the ability of REIT to consummate the transactions contemplated by this Agreement and the Transaction Documents to which it is a party.

(e)                                  Litigation.  There are no Proceedings pending or, to the knowledge of REIT, threatened, against REIT which, individually or in the aggregate, if determined adversely to REIT, would reasonably be expected to materially and adversely affect the ability of REIT to perform its obligations under this Agreement and the Transaction Documents to which it is a party.

(f)                                   Capitalization.  All of the outstanding REIT Common Shares are, and when issued pursuant to the terms of this Agreement upon receipt of payment therefor, the Subject REIT Shares will be, duly authorized, validly issued, fully paid and non-assessable.

(g)                                  Sophistication of Parties.  REIT has such knowledge, sophistication and experience in financial and business matters that REIT is capable of evaluating the merits and risks of its entering into this Agreement and the Transaction Documents to which it is a party and consummating the Transactions.

13

and has independently and without reliance upon any RMR Group Party (as defined below) made its own analysis and decision to accept the Subject Class A Shares in exchange for the Subject REIT Shares and the other Transactions.  REIT has relied solely on its own independent investigation in valuing the Subject Class A Shares and determining to proceed with this Agreement, the Transaction Documents to which it is a party and the Transactions.  REIT has not relied on any assertions made by TRUST or any RMR Entity or any Founder or any Person representing or acting on behalf of TRUST, any RMR Entity or any Founder (collectively, the “RMR Group Parties”) regarding the RMR Entities, the Subject Class A Shares or the valuation thereof.  REIT has previously undertaken such independent investigation of the RMR Entities as in its judgment is appropriate to make an informed decision with respect to the Transactions and has made its own decision to consummate the Transactions based on its own independent review and consultations with such investment, legal, tax, accounting and other advisers as it has deemed necessary; and

(ii)                                  REIT understands and acknowledges that, except as expressly otherwise set forth in Section 3.1, the RMR Group Parties do not make any representation or warranty to it, express or implied, with respect to the RMR Parties, the Subject Class A Shares, the Transactions or the accuracy, completeness or adequacy of any publicly available information regarding the RMR Parties or their subsidiaries, nor shall any of the RMR Group Parties be liable for any loss or damages of any kind resulting from the use of any information (other than any liability of the RMR Group Parties solely as a result of a material untruth or material inaccuracy of a representation or warranty of such parties set forth in Section 3.1) supplied to REIT.

(i)                                     Investment Purpose.  Except as provided in Section 4.3, REIT is acquiring the Subject Class A Shares for REIT’s own account for investment purposes only and not with a view to the distribution or resale thereof, in whole or in part, and agrees that it will not transfer, or offer to transfer, all or any portion of the Subject Class A Shares in any manner that would violate or cause INC to violate the Securities Act or any securities Laws of the several states.

ARTICLE IV

ADDITIONAL AGREEMENTS

Section 4.1                                    Registration Statement on Form S-1.

(a)                                 As promptly as reasonably practicable following the date of this Agreement, INC shall prepare (with the REIT’s reasonable cooperation) and cause to be filed with the SEC, a Registration Statement on Form S-1, including all exhibits and financial statements required under the Securities Act to be filed therewith (the “Form S-1”), in connection with the registration under the Securities Act of the Distribution Shares and the Other REIT Distribution Shares.  INC shall use its reasonable best efforts to (A) have the Form S-1 declared effective under the Securities Act as promptly as practicable after such filing, (B) ensure that the Form S-1 complies in all material respects with the applicable provisions of the Exchange Act and the Securities Act and (C) keep the Form S-1 effective for so long as necessary to complete the Distribution.  REIT shall furnish all information concerning itself and

14

its subsidiaries to INC and provide such other assistance as may be reasonably requested by INC in connection with the preparation, filing and distribution of the Form S-1 and related prospectus.  Each of INC and REIT shall provide to its and each other’s counsel such representations as reasonably necessary to render the opinions required to be filed therewith.  The Form S-1 shall include all information reasonably requested by INC and REIT to be included therein.  INC shall promptly notify REIT upon the receipt of any comments from the SEC or any request from the SEC for amendments or supplements to the Form S-1, and shall, as promptly as practicable after receipt thereof, provide REIT with copies of all correspondence between it and its Representatives, on the one hand, and the SEC, on the other hand, and all written comments with respect to the Form S-1 received from the SEC and advise REIT of any oral comments with respect to the Form S-1 received from the SEC.  INC shall use its reasonable best efforts to respond as promptly as practicable to any comments from the SEC with respect to the Form S-1.  Notwithstanding the foregoing, prior to filing the Form S-1 (or any amendment or supplement thereto) or responding to any comments from the SEC with respect thereto, INC shall cooperate with REIT and provide REIT a reasonable opportunity to review and comment on such document or response (including the proposed final version of such document or response).  INC shall advise REIT, promptly after it receives notice thereof, of the time of effectiveness of the Form S-1, the issuance of any stop order relating thereto or the suspension of the qualification of the Distribution Shares for offering or sale in any jurisdiction, and INC and REIT shall use their reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated.  INC shall also take any other action reasonably required to be taken under the Securities Act, the Exchange Act, any applicable foreign or state securities or “blue sky” Laws and the rules and regulations thereunder in connection with the distribution of the Distribution Shares, and REIT shall furnish all information concerning itself and the holders of the REIT Common Shares as may be reasonably requested in connection with any such actions.

(b)                                 If, at any time prior to effective date of the Distribution, any information relating to INC, REIT or any Other REIT should be discovered by INC or REIT which, in the reasonable judgment of INC or REIT, should be set forth in an amendment of, or a supplement to, the Form S-1, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party that discovers such information shall promptly notify the other Party, and INC and REIT shall cooperate in the prompt filing with the SEC of any necessary amendment of, or supplement to, the Form S-1 and, to the extent required by Law, in disseminating the information contained in such amendment or supplement to the shareholders of REIT.  For purposes of this Section 4.1, any information concerning or related to the RMR Parties or the Founders will be deemed to have been provided by INC, any information concerning or related to REIT or its subsidiaries will be deemed to have been provided by REIT and any information concerning or related to any Other REIT or its subsidiaries will be deemed to have been provided by such Other REIT.

(c)                                  LLC shall pay or promptly reimburse INC and REIT, as applicable, for all customary costs and expenses incident to the preparation and filing of the Form S-1 and the listing of the Class A Common Stock on a national securities exchange, including: (i) all SEC registration and filing fees; (ii) all fees and expenses to list the Class A Common Stock on a national securities exchange; (iii) fees and expenses of compliance with securities or “blue sky” Laws (including reasonable fees and disbursements of counsel in connection with blue sky

15

qualifications of the Distribution Shares); (iv) reasonable fees and disbursements of counsel to INC and fees and expenses for independent registered public accountants retained by INC (including the expenses or costs associated with the delivery of any consents and opinions); and (v) the fees and expenses of INC’s transfer agent and registrar.  For the avoidance of doubt, INC and LLC shall not have any obligation to pay or reimburse the fees and expenses of the Distribution Agent, REIT’s transfer agent and registrar, REIT’s counsel or the cost of printing or mailing any prospectus for the Distribution to REIT’s shareholders, all of which shall be paid by REIT.

Section 4.2                                    INC Charter, Board and Board Committees.  After the date of this Agreement and prior to the filing of the Form S-1, INC and REIT will discuss the advisability of including ownership limitations in INC’s charter comparable to those in REIT’s declaration of trust and will amend INC’s charter, if necessary.  Immediately prior to the time that the Form S-1 is declared effective under the Securities Act, (i) the Board of Directors of INC (the “INC Board”) shall be expanded to include not less than three (3) Independent Directors (the identity and qualifications of which shall have been previously approved by the independent trustees of REIT, which approval shall not be unreasonably withheld, conditioned or delayed), and (ii) the INC Board shall establish audit, compensation and nominating and governance committees thereof which comply with the Exchange Act and the listing requirements of any national securities exchange on which the Class A Common Stock has then been approved for listing.  Thereafter changes to the composition of INC Board and the committees thereof shall be made in accordance with INC’s organizational documents, as then in effect.

Section 4.3                                    Distribution.

(a)                                 As promptly as practicable following the time that the Form S-1 is declared effective under the Securities Act, REIT shall use reasonable best efforts to declare a pro rata distribution to holders of REIT Common Shares approximately half of the Subject Class A Shares received pursuant to Section 2.1(a) above (such distribution, the “Distribution,” and the shares to be distributed, the “Distribution Shares”).  REIT shall cooperate in good faith with INC and the Other REITs in choosing a distribution agent (the “Distribution Agent”) and establishing a record date and distribution date for the Distribution such that the record dates and distribution dates for the distributions of shares of Class A Common Stock to be made by REIT and by the Other REITs pursuant to the Other REIT Transaction Agreements are as close in time as practicable to each other and to the effective date of the Form S-1.

(b)                                 REIT shareholders holding a number of REIT Common Shares on the Distribution record date, which would entitle such shareholders to receive less than one whole Distribution Share in the Distribution, will receive cash in lieu of fractional shares. Fractional Distribution Shares will not be distributed in the Distribution nor credited to book-entry accounts.  The Distribution Agent shall, as soon as practicable after the Distribution date (i) determine the number of whole and fractional Distribution Shares allocable to each holder of record or beneficial owner of REIT Common Shares as of close of business on the Distribution record date, (ii) aggregate all such fractional shares into whole shares and sell the whole shares obtained thereby in open market transactions, in each case, at the then prevailing trading prices on behalf of holders who would otherwise be entitled to fractional share interests and (iii) distribute to each such holder, or for the benefit of each such beneficial owner, such holder

16

or owner’s ratable share of the net proceeds of such sale, based upon the average gross selling price per Distribution Share after making appropriate deductions for any amount required to be withheld for tax purposes and any brokerage fees incurred in connection with these sales of fractional shares.  None of REIT, INC or the Distribution Agent will guarantee any minimum resale price for the fractional Distribution Shares.  INC will not pay any interest on the proceeds from the sale of fractional shares.  The Distribution Agent acting on behalf of REIT will have the sole discretion to select the broker-dealers through which to sell the aggregated fractional shares and to determine when, how and at what price to sell such shares.

Section 4.4                                    Exchange Listing.  INC shall use its best efforts to have the issued and outstanding Class A Common Stock (including the Distribution Shares) approved for listing on a national securities exchange, as defined under the Exchange Act, on or prior to the earliest distribution date.

Section 4.5                                    Transfer Agent.  INC shall use its best efforts to provide and cause to be maintained a transfer agent and registrar (which may be the same entity) for the Distribution Shares and obtain a CUSIP number for the Class A Common Stock, in each case, no later than the effective date of the Form S-1.

ARTICLE V

Section 5.1                                    Indemnification by LLC.  LLC shall indemnify and hold harmless REIT, its subsidiaries, each of their respective directors, trustees, officers and agents, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “REIT Indemnified Parties”) from and against any and all damages, claims, losses, expenses, costs, obligations and liabilities, including liabilities for all reasonable attorneys’, accountants’, and experts’ fees and expenses (collectively, “Covered Liabilities”), suffered, directly or indirectly, by any REIT Indemnified Party by reason of, or arising out of any untrue statement or alleged untrue statement of a material fact contained in the Form S-1 (or any amendment thereto), including any omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact in the Form S-1 or the omission or alleged omission therefrom of a material fact necessary in order to make the statement therein in light of the circumstances under which they were made, not misleading, in each case other than any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to INC by REIT or any Other REIT for use in the Form S-1 (or any amendment thereto).

If any indemnified party recovers an amount from a third party in respect of an indemnifiable loss for which indemnification is provided in this Agreement after the full amount of such indemnifiable loss has been paid by an indemnifying party or after an indemnifying party has made a partial payment of such indemnifiable loss and the amount received from the third party exceeds the remaining unpaid balance of such indemnifiable loss, then the indemnified party shall promptly remit to the indemnifying party the excess of (i) the sum of the amount theretofore paid by such indemnifying party in respect of such indemnifiable loss plus the amount received from the third party in respect thereof, less (ii) the full amount of such Covered Liabilities.

(a)                                 Governing Law.  This Agreement and any Dispute, whether in contract, tort or otherwise, shall be governed by and construed in accordance with the laws of the State of Maryland without regard to principles of conflicts of law.

(b)                                 Venue.  Each Party agrees that it shall bring any Proceeding in respect of any claim arising out of or related to this Agreement or the Transactions exclusively in the courts of the State of Maryland and the Federal courts of the United States, in each case, located in the City of Baltimore (the “Chosen Courts”).  Solely in connection with claims arising under this Agreement or the Transactions, each Party irrevocably and unconditionally (i) submits to the exclusive jurisdiction of the Chosen Courts, (ii) agrees not to commence any such Proceeding except in such courts, (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such Proceeding in the Chosen Courts, (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such Proceeding and (v) agrees that service of process upon such Party in any such Proceeding shall be effective if notice is given in accordance with Section 7.1.  Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by Law.  A final judgment in any such Proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.  EACH PARTY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS.  Notwithstanding anything herein to the contrary, if a demand for arbitration of a Dispute is made pursuant to Section 7.5(c), this Section 7.5(b) shall not pre-empt resolution of the Dispute pursuant to Section 7.5(c).

(c)                                  Arbitration.

(i)                                     Any disputes, claims or controversies arising out of or relating to this Agreement, any Transaction Document or the Transactions, including any disputes, claims or controversies brought by or on behalf of a Party or any holder of equity interests (which, for purposes of this Section 7.5(c), shall mean any holder of record or any beneficial owner of equity interests, or any former holder of record or beneficial owner of equity interests) of a Party, either on his, her or its own behalf, on behalf of a Party or on behalf of any series or class of equity interests of a Party or holders of equity interests of a Party against a Party or any of their respective trustees, directors, members, officers, managers, agents or employees, including any disputes, claims or controversies relating to the meaning, interpretation, effect, validity, performance or enforcement of this Agreement, including this arbitration agreement, any Transaction Document or the Transactions or the governing documents of a Party, (all of which are referred to as “Disputes”) or relating in any way to

21

such a Dispute or Disputes shall, on the demand of any party to such Dispute or Disputes, be resolved through binding and final arbitration in accordance with the Commercial Arbitration Rules (the “Rules”) of the American Arbitration Association (“AAA”) then in effect, except as those Rules may be modified in this Section 7.5(c).  For the avoidance of doubt, and not as a limitation, Disputes are intended to include derivative actions against the trustees, directors, officers or managers of a Party and class actions by a holder of equity interests against those individuals or entities and a Party.  For the avoidance of doubt, a Dispute shall include a Dispute made derivatively on behalf of one party against another party.  For purposes of this Section 7.5(c), the term “equity interest” shall mean, (i) in respect of INC, shares of capital stock of INC, (ii) in respect of LLC, “membership interest” in LLC as defined in the Maryland Limited Liability Companies Act and (iii) in respect of REIT and TRUST, shares of beneficial interest of REIT and TRUST, respectively.

(ii)                                  There shall be three (3) arbitrators.  If there are only two (2) parties to the Dispute, each party shall select one (1) arbitrator within fifteen (15) days after receipt by respondent of a copy of the demand for arbitration.  The arbitrators may be affiliated or interested persons of the parties.  If there are more than two (2) parties to the Dispute, all claimants, on the one hand, and all respondents, on the other hand, shall each select, by the vote of a majority of the claimants or the respondents, as the case may be, one (1) arbitrator within fifteen (15) days after receipt of the demand for arbitration. The arbitrators may be affiliated or interested persons of the claimants or the respondents, as the case may be.  If either a claimant (or all claimants) or a respondent (or all respondents) fail(s) to timely select an arbitrator then the party (or parties) who has selected an arbitrator may request AAA to provide a list of three (3) proposed arbitrators in accordance with the Rules (each of whom shall be neutral, impartial and unaffiliated with any party) and the party (or parties) that failed to timely appoint an arbitrator shall have ten (10) days from the date AAA provides the list to select one (1) of the three (3) arbitrators proposed by AAA.  If the party (or parties) fail(s) to select the second (2nd) arbitrator by that time, the party (or parties) who have appointed the first (1st) arbitrator shall then have ten (10) days to select one (1) of the three (3) arbitrators proposed by AAA to be the second (2nd) arbitrator; and, if he/they should fail to select the second (2nd) arbitrator by such time, AAA shall select, within fifteen (15) days thereafter, one (1) of the three (3) arbitrators it had proposed as the second (2nd) arbitrator.  The two (2) arbitrators so appointed shall jointly appoint the third (3rd) and presiding arbitrator (who shall be neutral, impartial and unaffiliated with any party) within fifteen (15) days of the appointment of the second (2nd) arbitrator.  If the third (3rd) arbitrator has not been appointed within the time limit specified herein, then AAA shall provide a list of proposed arbitrators in accordance with the Rules, and the arbitrator shall be appointed by AAA in accordance with a listing, striking and ranking procedure, with each party having a limited number of strikes, excluding strikes for cause.

(iii)                               The place of arbitration shall be Boston, Massachusetts unless otherwise agreed by the parties.  There shall be only limited documentary discovery of documents directly related to the issues in dispute, as may be ordered by the arbitrators.  For the avoidance of doubt, it is intended that there shall be no depositions and no other discovery other than limited documentary discovery as described in the preceding sentence.

(iv)                              In rendering an award or decision (the “Award”), the arbitrators shall be required to follow the Laws of the State of Maryland.  Any arbitration proceedings or award rendered hereunder and the validity, effect and interpretation of this arbitration agreement shall be governed by the Federal Arbitration Act, 9 U.S.C. §1 et seq.  The Award shall be in writing and shall state the findings of fact and conclusions of law on which it is based.  Any monetary award shall be made and payable in Dollars free of any tax, deduction or offset.  Subject to Section 7.5(c)(vi), each party against which the Award assesses a monetary obligation shall pay that obligation on or before the thirtieth (30th) day following the date of the Award or such other date as the Award may provide.

(v)                                 Except to the extent expressly provided by this Agreement or as otherwise agreed by the parties thereto, each party involved in a Dispute shall bear its own costs and expenses (including attorneys’ fees), and the arbitrators shall not render an award that would include shifting of any such costs or expenses (including attorneys’ fees) or, in a derivative case or class action, award any portion of a party’s award to the claimant or the claimant’s attorneys.  Each party (or, if there are more than two (2) parties to the Dispute, all claimants, on the one hand, and all respondents, on the other hand, respectively) shall bear the costs and expenses of its (or their) selected arbitrator and the parties (or, if there are more than two (2) parties to the Dispute, all claimants, on the one hand, and all respondents, on the other hand) shall equally bear the costs and expenses of the third (3rd) appointed arbitrator.

(vi)                              Notwithstanding any language to the contrary in this Agreement, the Award, including but not limited to any interim Award, may be appealed pursuant to the AAA’s Optional Appellate Arbitration Rules (“Appellate Rules”).  The Award shall not be considered final until after the time for filing the notice of appeal pursuant to the Appellate Rules has expired.  Appeals must be initiated within thirty (30) days of receipt of the Award by filing a notice of appeal with any AAA office. Following the appeal process, the decision rendered by the appeal tribunal may be entered in any court having jurisdiction thereof.  For the avoidance of doubt, and despite any contrary provision of the Appellate Rules, Section 7.5(c)(v) hereof shall apply to any appeal pursuant to this Section and the appeal tribunal shall not render an award that would include shifting of any costs or expenses (including attorneys’ fees) of any party.

(vii)                           Following the expiration of the time for filing the notice of appeal, or the conclusion of the appeal process set forth in Section 7.5(c)(vi), the Award shall be final and binding upon the parties thereto and shall be the sole and exclusive remedy between those parties relating to the Dispute, including any claims, counterclaims, issues or accounting presented to the arbitrators.  Judgment upon the Award may be entered in any court having jurisdiction.  To the fullest extent permitted by Law, no application or appeal to any court of competent jurisdiction may be made in connection with any question of law arising in the course of arbitration or with respect to any award made except for actions relating to enforcement of this agreement to arbitrate or any arbitral award issued hereunder and except for actions seeking interim or other provisional relief in aid of arbitration proceedings in any court of competent jurisdiction.

Section 7.6                                    Severability.  This Agreement and the Transaction Documents shall be interpreted in such manner as to be effective and valid under applicable Law.  If at any time subsequent to the date hereof, any provision of this Agreement or any Transaction Document is determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of Law or public policy in any respect, such provision will be enforced to the maximum extent possible given the intent of the Parties or the parties thereto.

Section 7.7                                    Counterparts.  This Agreement may be executed in any number of counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to the other Party (including via facsimile or other electronic transmission), it being understood that each Party need not sign the same counterpart.
