SECTION 6
MISCELLANEOUS

6.1 Disputes. Notwithstanding anything in the Existing Arrangements to the contrary, the parties agree:

(1) Disputes. Any disputes, claims or controversies between the parties (a) arising out of or relating to the Existing Arrangements, the Transaction Documents or the transactions contemplated thereby, or (b) brought by or on behalf of any shareholder of any party or a direct or indirect parent of a party (which, for purposes of this Section 6.1, shall mean any shareholder of record or any beneficial owner of shares of any party, or any former shareholder of record or beneficial owner of shares of any party), either on his, her or its own behalf, on behalf of any party or on behalf of any series or class of shares of any party or shareholders of any party against any party or any member, trustee, officer, manager (including The RMR Group LLC or its successor), agent or employee of any party, including disputes, claims or controversies relating to the meaning, interpretation, effect, validity, performance or enforcement of the Existing Arrangements or the Transaction Documents, including this arbitration provision, or the declarations of trust, limited liability company agreements, charters, bylaws or other governing documents of any party hereto (all of which are referred to as “Disputes”), or relating in any way to such a Dispute or Disputes shall, on the demand of any party to such Dispute 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 6.1. For the avoidance of doubt, and not as a limitation, Disputes are intended to include derivative actions against trustees, officers or managers of any party and class actions by a shareholder against those individuals or entities and any 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 6.1, the term “party” shall include any direct or indirect parent of a party.

(2) Selection of Arbitrators. There shall be three (3) arbitrators. If there are only two (2) parties to the Dispute, each party shall select one arbitrator within fifteen (15) days after receipt of a demand for arbitration. Such arbitrators may be affiliated or interested persons of such 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 arbitrator within fifteen (15) days after receipt of a demand for arbitration. Such 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 to timely select an arbitrator then the party (or parties) who has selected an arbitrator may request the 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 the AAA provides such list to select one of the three (3) arbitrators proposed by AAA. If such party (or parties) fail to select such arbitrator by such time, the party (or parties) who have appointed the first arbitrator shall then have ten

9

(10) days to select one of the three (3) arbitrators proposed by AAA to be the second arbitrator; and, if he/they should fail to select such arbitrator by such time, the AAA shall select, within fifteen (15) days thereafter, one of the three (3) arbitrators it had proposed as the second arbitrator. The two (2) arbitrators so appointed shall jointly appoint the third and presiding arbitrator (who shall be neutral, impartial and unaffiliated with any party) within fifteen (15) days of the appointment of the second arbitrator. If the third arbitrator has not been appointed within the time limit specified herein, then the AAA shall provide a list of proposed arbitrators in accordance with the Rules, and the arbitrator shall be appointed by the AAA in accordance with a listing, striking and ranking procedure, with each party having a limited number of strikes, excluding strikes for cause.

(3) Location of Arbitration. The place of arbitration shall be Boston, Massachusetts unless otherwise agreed by the parties.

(4) Scope of Discovery. There shall be only limited documentary discovery of documents directly related to the issues in dispute, as may be ordered by the arbitrators.

(5) Arbitration Award. In rendering an award or decision (the “Arbitration Award”), the arbitrators shall be required to follow the laws of the State of Maryland. Any arbitration proceedings or Arbitration 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 Arbitration Award shall be in writing and may, but shall not be required to, briefly state the findings of fact and conclusions of law on which it is based.

(6) Costs. Except to the extent expressly provided by this Agreement or as otherwise agreed by the parties, 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 appointed arbitrator.

(7) Final Judgment. An Arbitration Award shall be final and binding upon the parties thereto and shall be the sole and exclusive remedy between such parties relating to the Dispute, including any claims, counterclaims, issues or accounting presented to the arbitrators. Judgment upon the Arbitration 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

10

hereunder and except for actions seeking interim or other provisional relief in aid of arbitration proceedings in any court of competent jurisdiction.

(8) Payment. Any monetary award shall be made and payable in U.S. dollars free of any tax, deduction or offset. Each party against which the Arbitration Award assesses a monetary obligation shall pay that obligation on or before the thirtieth (30th) day following the date of the Arbitration Award or such other date as the Arbitration Award may provide.

(9) Intended Beneficiaries. This Section 6.1 is intended to benefit and be enforceable by the shareholders, members, direct and indirect parents, trustees, directors, officers, managers (including The RMR Group LLC or its successor), agents or employees of any party and the parties and shall be binding on the shareholders of any party and the parties, as applicable, and shall be in addition to, and not in substitution for, any other rights to indemnification or contribution that such individuals or entities may have by contract or otherwise.

6.2 Confidentiality. Each party shall use commercially reasonable efforts to maintain the confidentiality of any information concerning the parties or any subsidiary of another party provided to or discovered by it or its representatives as a result of the transaction contemplated by the Transaction Documents and which is not otherwise available on a nonconfidential basis to such party and shall not (except as may otherwise be required by applicable law or the rules and regulations of the National Association of Securities Dealers Automated Quotations System, the New York Stock Exchange or the American Stock Exchange) disclose such information, subject to the provisions of this Section, to anyone other those persons who have a need to know such information in connection with the conduct of such party’s business, including its attorneys, accountants and other representatives and agents or during the course of or in connection with any litigation or other action, arbitration, investigation or other proceeding based upon or in connection with the subject matter of this Agreement or the transactions contemplated hereby.

13

provision with any constitution or statute or rule of public policy or for any other reason, such circumstance shall not have the effect of rendering the provision or provisions in question invalid, inoperative or unenforceable in any other jurisdiction or in any other case or circumstance or of rendering any other provision or provisions herein contained invalid, inoperative or unenforceable to the extent that such other provisions are not themselves actually in conflict with such constitution, statute or rule of public policy, but this Agreement shall be reformed and construed in any such jurisdiction or case as if such invalid, inoperative or unenforceable provision had never been contained herein and such provision reformed so that it would be valid, operative and enforceable to the maximum extent permitted in such jurisdiction or in such case.

Section 3. General Representations, Warranties and Covenants. Tenant represents, warrants and covenants, which representations, warranties and covenants shall survive execution and delivery of this Agreement, as follows:

(a) Each of the warranties and representations of Tenant contained herein, in Lease No. 5 or in any other document executed in connection herewith or therewith are true and correct on the date hereof.

(b) Except for the lien granted to the Secured Party pursuant to this Agreement and any liens permitted under Lease No. 5, Tenant is, and as to the Collateral acquired from time to time after the date hereof Tenant will be, the owner of all the Collateral free from any lien, security interest, encumbrance or other right, title or interest of any Person, except for the security interest of the Secured Party therein, and Tenant shall defend the Collateral against all claims and demands of all Persons at any time claiming the same or any interest therein adverse to the Secured Party. The lien granted in this Agreement by Tenant to the Secured Party in the Collateral is not prohibited by and does not constitute a default under any agreements or other instruments constituting a part of the Collateral, and no consent is required of any Person to effect such lien which has not been obtained.

(c) Except as permitted under Lease No. 5, there is no financing statement (or similar statement or instrument of registration under the law of any jurisdiction) now on file or registered in any public office covering any interest of any kind in the Collateral, or intended so to be, which has not been terminated, and so long as this Agreement remains in effect or any of the Obligations or any obligations of any Affiliated Person of Tenant to the Secured Party remain unpaid, Tenant will not execute and there will not be on file in any public office any financing statement (or similar statement or instrument of registration under the law of any jurisdiction) or statements relating to the Collateral, except financing statements filed or to be filed in respect of and covering the security interest of the Secured Party.

(d) The chief executive office and the principal place of business of Tenant are as set forth in Schedule 1 and Tenant will not move its chief executive office or establish any other principal place of business except to such new location as Tenant may establish in accordance with this Section 3(d). The location of each Facility comprising a portion of the Leased Property is as set forth in Schedule 2. The originals of all documents evidencing Collateral and the only original books of account and records of Tenant relating thereto are, and will continue to be, kept at such chief executive office or the applicable Facility, as the case may be, or at such new location as Tenant may establish in accordance with this Section 3(d). Tenant shall not move its chief executive office or establish any other principal place of business until (i) Tenant shall have given to the Secured Party not less than ten (10) days’ prior written notice of its intention to do so, which notice shall clearly describe such new location and provide such other information in connection therewith as the Secured Party may reasonably request, and (ii) with respect to such new location, Tenant shall have taken such action, satisfactory to the

4

Secured Party (including, without limitation, all action required by Section 5), to maintain the security interest of the Secured Party in the Collateral.

(e) All tangible personal property owned on the date hereof by Tenant to be used in connection with the operation or maintenance of the Leased Property, or any portion thereof, is located at each applicable Property or is in transit to such Property from the vendor thereof. Tenant agrees that (i) all such property held by Tenant on the date hereof, once at each applicable Property, shall remain at such Property and (ii) all such property subsequently acquired by Tenant shall immediately upon acquisition be transferred to and remain at the applicable Property.

(f) The corporate name and organizational identification number of Tenant is set forth on the signature page hereto. The name under which each of the Facilities is operated is set forth on Schedule 2. Tenant shall not (i) change such name without providing the Secured Party with thirty (30) days’ prior written notice and making all filings and taking all such other actions as the Secured Party determines are necessary or appropriate to continue or perfect the security interest granted hereunder, (ii) change its corporate organizational number, nor (iii) conduct its business in any other name or take title to any Collateral in any other name while this Agreement remains in effect. Except as otherwise set forth on Schedule 1, Tenant has not ever had any other name nor conducted business in any other name in any jurisdiction. Tenant is organized as a Maryland statutory trust. Subject to the terms and conditions of Lease No. 5, Tenant shall not change its organizational structure or jurisdiction of organization without giving at least thirty (30) days’ prior written notice thereof to the Secured Party.

(g) The Secured Party is authorized (but is under no obligation) to make, upon ten (10) Business Days’ notice to Tenant (except in the case of exigent circumstances, in which circumstances upon such notice, if any, as may then be reasonably practical), any payments which in the Secured Party’s opinion are necessary to:

(i) discharge any liens which have or may take priority over the lien hereof; and

(ii) pay all premiums payable on the insurance policies referred to in Lease No. 5 or any other document or agreement executed in connection therewith or herewith, upon the failure of Tenant to make such payments within the time permitted therein.

Tenant shall have no claim against the Secured Party by reason of its decision not to make any payments or perform such obligations permitted under this Section 3(g). Tenant shall repay to the Secured Party any sums paid by the Secured Party upon demand. Any sums paid and expenses incurred by the Secured Party pursuant to this paragraph shall bear interest at the Overdue Rate.

(h) If any of the Collateral at any time becomes evidenced by an Instrument, Tenant shall promptly deliver such Instrument to the Secured Party, appropriately endorsed to the order of the Secured Party, to be held pursuant to this Agreement.

5

(i) Tenant shall not sell, transfer, change the registration, if any, of, dispose of, attempt to dispose of, or substantially modify or abandon the Collateral or any material part thereof, other than as permitted under Lease No. 5, without the prior written consent of the Secured Party. Except as permitted under Lease No. 5, Tenant shall not create, incur, assume or suffer to exist any lien upon any of the Collateral without the prior written consent of the Secured Party.

(j) Tenant shall not assert against the Secured Party any claim or defense which Tenant may have against any seller of the Collateral or any part thereof or against any Person with respect to the Collateral or any part thereof.

(k) Tenant shall, upon demand, pay to the Secured Party the amount of any and all reasonable expenses, including the reasonable fees and expenses of its counsel and of any experts and agents, which the Secured Party may incur in connection with (i) the administration of this Agreement, (ii) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Collateral, (iii) the exercise or enforcement of any of the rights of the Secured Party hereunder and under such other agreements or (iv) the failure by Tenant to perform or observe any of the provisions hereof.

(l) Tenant shall indemnify and hold harmless the Secured Party from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Secured Party in any way relating to or arising out of this Agreement or arising out of Tenant’s obligations under any other documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or the enforcement of any of the terms hereof or of any such other documents.

Section 4. Special Provisions Concerning Equipment. Tenant shall not impair the rights of the Secured Party in the Equipment. Regardless of the manner of the affixation of any Equipment to real property, the Equipment so attached shall at all times constitute and remain personal property. Tenant retains all liability and responsibility in connection with the Equipment and the liability of Tenant to pay the Obligations shall in no way be affected or diminished by reason of the fact that such Equipment may be lost, destroyed, stolen or damaged or for any reason whatsoever have become unavailable to Tenant. Upon the request of the Secured Party, Tenant shall provide to the Secured Party a current list of Equipment.

Section 5. Financing Statements; Documentary Stamp Taxes.

(a) Tenant shall, at its own expense, make, execute, endorse, acknowledge, file and/or deliver to the Secured Party from time to time such lists, descriptions and designations of inventory, warehouse receipts, bills of lading, documents of title, vouchers, invoices, schedules, confirmatory assignments, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, reports and other assurances or instruments and take such further steps relating to the Collateral and other property or rights covered by the security interest hereby granted, which the Secured Party reasonably deems appropriate or advisable to perfect, preserve or protect its security interest in the Collateral. Tenant authorizes the Secured Party to file any such financing statements without the signature of Tenant and Tenant will pay all applicable filing fees and related expenses. To the extent permitted by law, a carbon, photographic or other

6

reproduction of this Agreement or a financing statement shall be sufficient as a financing statement.

(b) Tenant shall procure, pay for, affix to any and all documents and cancel any documentary tax stamps required by and in accordance with, applicable law, and Tenant shall indemnify and hold harmless the Secured Party from and against any liability (including interest and penalties) in respect of such documentary stamp taxes.

Section 6. Event of Default. For purposes of this Agreement, the term “Event of Default” shall mean (a) the occurrence of an Event of Default under Lease No. 5 or any document or agreement executed in connection therewith; (b) the failure of Tenant to comply with any of its covenants or obligations under this Agreement and the continuance thereof for a period of ten (10) Business Days after written notice thereof; (c) any representation or warranty contained herein or made by Tenant in connection herewith shall prove to have been false or misleading in any material respect when made; or (d) the occurrence of any default or event of default under any document, instrument or agreement evidencing the Obligations.

Section 7. Remedies.

(a) Upon the occurrence and during the continuance of an Event of Default, in addition to any rights and remedies now or hereafter granted under applicable law, under Lease No. 5 or under any other documents or agreements entered into in connection herewith or therewith, and not by way of limitation of any such rights and remedies, the Secured Party shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as enacted in any applicable jurisdiction, and the right, without notice to, or assent by, Tenant, in the name of Tenant or, subject to any limitations imposed by applicable Legal Requirements in the name of the Secured Party or otherwise:

(ii) to take possession of any or all of the Collateral and to use, hold, store, operate, merge and/or control the same and to exclude Tenant and all Persons claiming under it wholly or partly therefrom, and, for that purpose, to enter, with the aid and assistance of any Person or Persons and with or without legal process, any premises where the Collateral, or any part thereof, are, or may be, placed or assembled, and to remove any such Collateral;

(iii) from time to time, at the expense of Tenant, to make all such repairs, replacements, alterations, additions and improvements to and of the Collateral as the Secured Party may reasonably deem proper; to carry on

7

the business and to exercise all rights and powers of Tenant in respect to the Collateral, as the Secured Party shall deem best, including the right to enter into any and all such agreements with respect to the leasing, management and/or operation of the Collateral or any part thereof as the Secured Party may see fit; to collect and receive all rents, issues, profits, fees, revenues and other income of the same and every part thereof which rents, issues, profits, fees, revenues and other income may be applied to pay the expenses of holding and operating the Collateral and of conducting the business thereof, and of all maintenance, repairs, replacements, alterations, additions and improvements, and to make all payments which the Secured Party may be required or may elect to make, if any, for taxes, assessments, insurance and other charges upon the Collateral or any part thereof, and all other payments which the Secured Party may be required or authorized to make under any provision of this Agreement (including, without limitation, reasonable legal costs and attorneys’ fees);

(iv) to execute any instrument and do all other things necessary and proper to protect and preserve and realize upon the Collateral and the other rights contemplated hereby;

(v) upon notice to such effect, to require Tenant to deliver, at Tenant’s expense, any or all Collateral which is reasonably movable to the Secured Party at a place designated by the Secured Party, and after delivery thereof Tenant shall have no further claim to or interest in the Collateral; and

(vi) without obligation to resort to other security, at any time and from time to time, to sell, re-sell, assign and deliver all or any of the Collateral, in one or more parcels at the same or different times, and all right, title and interest, claim and demand therein and right of redemption thereof, at public or private sale, for cash, upon credit or for future delivery, and at such price or prices and on such terms as the Secured Party may determine, with the amounts realized from any such sale to be applied to the Secured Obligations in the manner determined by the Secured Party.

Tenant hereby agrees that all of the foregoing may be effected without demand, advertisement or notice (except as hereinafter provided or as may be required by law), all of which (except as hereinafter provided) are hereby expressly waived, to the maximum extent permitted by law. The Secured Party shall not be obligated to do any of the acts hereinabove authorized and in the event that the Secured Party elects to do any such act, the Secured Party shall not be responsible to Tenant.

(b) Upon the occurrence and during the continuance of an Event of Default, the Secured Party may take legal proceedings for the appointment of a receiver or receivers (to which the Secured Party shall be entitled as a matter of right) to take possession of the Collateral pending the sale thereof pursuant either to the powers of sale granted by this Agreement or to a judgment, order or decree made in any judicial proceeding for the foreclosure or involving the

8

enforcement of this Agreement. If, after the exercise of any or all of such rights and remedies, any of the Obligations shall remain unpaid or unsatisfied, Tenant shall remain liable for any deficiency or performance thereof, as applicable.

(c) Upon any sale of any of the Collateral, whether made under the power of sale hereby given or under judgment, order or decree in any judicial proceeding for the foreclosure or involving the enforcement of this Agreement:

(i) the Secured Party may bid for and purchase the property being sold and, upon compliance with the terms of sale, may hold, retain and possess and dispose of such property in its own absolute right without further accountability, and may, in paying the purchase money therefor, deliver any instruments evidencing the Obligations or agree to the satisfaction of all or a portion of the Obligations in lieu of cash in payment of the amount which shall be payable thereon, and such instruments, in case the amounts so payable thereon shall be less than the amount due thereon, shall be returned to the Secured Party after being appropriately stamped to show partial payment;

(ii) the Secured Party may make and deliver to the purchaser or purchasers a good and sufficient deed, bill of sale and instrument of assignment and transfer of the property sold;

(iv) the receipt of the Secured Party or of the officers thereof making such sale shall be a sufficient discharge to the purchaser or purchasers at such sale for his or their purchase money, and such purchaser or purchasers, and his or their assigns or personal representatives, shall not, after paying such purchase money and receiving such receipt of the Secured Party or of such officer therefor, be obliged to see to the application of such purchase money or be in any way answerable for any loss, misapplication or nonapplication thereof; and

(v) to the extent that it may lawfully do so, Tenant agrees that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take advantage of, any appraisement, valuation, stay, extension or redemption laws, or any law permitting it to direct the order in which the Collateral or any part thereof shall be sold, now or at any time hereafter in force, which may delay, prevent or otherwise affect the performance or enforcement of this Agreement or any other document, Lease No. 5 or any other document or agreement entered into in connection herewith or therewith, and Tenant hereby expressly waives all benefit or advantage

9

of any such laws and covenants that it will not hinder, delay or impede the execution of any power granted or delegated to the Secured Party in this Agreement, but will suffer and permit the execution of every such power as though no such laws were in force.

In the event of any sale of Collateral pursuant to this Section 7, the Secured Party shall, at least ten (10) days before such sale, give Tenant written notice of its intention to sell, except that, if the Secured Party shall determine in its reasonable discretion that any of the Collateral threatens to decline in value, any such sale may be made upon three (3) days’ written notice to Tenant, which time periods Tenant hereby agrees are reasonable.

(d) The Secured Party is hereby irrevocably appointed the true and lawful attorney-in-fact of Tenant in its name and stead, to make all necessary deeds, bills of sale and instruments of assignment and transfer of the property sold pursuant to this Section 7 and for such other purposes as are necessary or desirable to effectuate the provisions of this Agreement, and for that purpose it may execute and deliver all necessary deeds, bills of sale and instruments of assignment and transfer, and may substitute one or more Persons with like power, Tenant hereby ratifying and confirming all that its said attorney, or such substitute or substitutes, shall lawfully do by virtue hereof. If so requested by the Secured Party or by any purchaser, Tenant shall ratify and confirm any such sale or transfer by executing and delivering to the Secured Party or to such purchaser all property, deeds, bills of sale, instruments or assignment and transfer and releases as may be designated in any such request.

Section 8. Application of Moneys. All moneys which the Secured Party shall receive pursuant hereto shall first be applied (to the extent thereof) to the payment of all reasonable costs and expenses incurred in connection with the administration and enforcement of, or the preservation of any rights under, this Agreement or Lease No. 5 (including, without limitation, the reasonable fees and disbursements of its counsel and agents) and the balance, if any, shall be applied first to accrued and unpaid interest, charges and fees on, and then to outstanding principal of, any Obligations or any other obligations of Tenant (or its affiliates) to the Secured Party, and then to any other amounts outstanding on any such Obligations and then as required by law to any other parties having an interest therein.

Section 9. Waivers, Etc. Tenant, on its own behalf and on behalf of its successors and assigns, hereby waives presentment, demand, notice, protest and, except as is otherwise specifically provided herein, all other demands and notices in connection with this Agreement or the enforcement of the rights of the Secured Party hereunder or in connection with any Obligations or any Collateral; waives all rights to require a marshaling of assets by the Secured Party; consents to and waives notice of (a) the substitution, release or surrender of any Collateral, (b) the addition or release of Persons primarily or secondarily liable on any Obligation or on any Collateral, (c) the acceptance of partial payments on any Collateral and/or the settlement or compromise thereof, (d) any requirement of diligence or promptness on the part of the Secured Party in the enforcement of any rights in respect of any Collateral or any other agreement or instrument directly or indirectly relating thereto, and (e) any enforcement of any present or future agreement or instrument relating directly or indirectly to the Collateral. No delay or omission on the part of the Secured Party or any holder of Obligations in exercising any right hereunder shall operate as a waiver of such right or of any other right hereunder. No waiver of any such right on

10

any one occasion shall be construed as a bar to or waiver of any such right on any future occasion. No course of dealing between Tenant and the Secured Party or any holder of Obligations, nor any failure to exercise, nor any delay in exercising, on the part of the Secured Party or any holder of Obligations, any right, power or privilege hereunder or under any of the Obligations, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof, or the exercise of any other right, power or privilege.

Tenant further waives any right it may have under the constitution of any state or commonwealth in which any of the Collateral may be located, or under the Constitution of the United States of America, to notice (except for notice specifically required hereby) or to a judicial hearing prior to the exercise of any right or remedy provided by this Agreement to the Secured Party, and waives its rights, if any, to set aside or invalidate any sale duly consummated in accordance with the foregoing provisions hereof on the grounds (if such be the case) that the sale was consummated without a prior judicial hearing. TENANT’S WAIVERS UNDER THIS SECTION 9 HAVE BEEN MADE VOLUNTARILY, INTELLIGENTLY AND KNOWINGLY AND AFTER TENANT HAS BEEN APPRISED AND COUNSELED BY ITS ATTORNEYS AS TO THE NATURE THEREOF AND ITS POSSIBLE ALTERNATIVE RIGHTS.

The Secured Party shall not be required to marshal any present or future security for (including without limitation this Agreement and the Collateral pledged hereunder), or guaranties of, the Obligations or any of them, or to resort to such security or guaranties in any particular order; and all of the rights hereunder and in respect of such securities and guaranties shall be cumulative and in addition to all other rights, however existing or arising. To the maximum extent permitted by applicable law, Tenant hereby agrees that it will not invoke any law relating to the marshalling of collateral, which might cause delay in or impede the enforcement of the Secured Party’s rights under this Agreement or under any other instrument evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or guaranteed, and, to the maximum extent permitted by applicable law, Tenant hereby irrevocably waives the benefits of all such laws.

Section 10. Further Assurances as to Collateral; Attorney-in-Fact. From time to time hereafter, Tenant will execute and deliver, or will cause to be executed and delivered, such additional instruments, certificates or documents (including, without limitation, financing statements, renewal statements, mortgages, collateral assignments and other security documents), and will take all such actions as the Secured Party may reasonably request, for the purposes of implementing or effectuating the provisions of this Agreement or of more fully perfecting or renewing the Secured Party’s rights with respect to the Collateral (or with respect to any additions thereto or replacements or proceeds thereof or with respect to any other property or assets hereafter acquired by Tenant which may be deemed to be a part of the Collateral) pursuant hereto and thereto. The Secured Party is hereby appointed the attorney-in-fact, with full power of substitution, of Tenant for the purpose of carrying out the provisions of this Agreement and taking any action, including, without limitation, executing, delivering and filing applications, certificates, instruments and other documents and papers with governmental authorities, and executing any instruments, including without limitation financing or continuation statements, deeds to secure debt, mortgages, assignments, conveyances, assignments and transfers which are required to be taken or executed by Tenant under this Agreement, on its behalf and in its name

11

which appointment is coupled with an interest, is irrevocable and durable and shall survive the subsequent dissolution, disability or incapacity of Tenant.

Section 11. Arbitration.

11.1 Disputes. Any disputes, claims or controversies between the parties (a) arising out of or relating to this Agreement, or (b) brought by or on behalf of any shareholder of any party or a direct or indirect parent of a party (which, for purposes of this Section 11, shall mean any shareholder of record or any beneficial owner of shares of any party, or any former shareholder of record or beneficial owner of shares of any party), either on his, her or its own behalf, on behalf of any party or on behalf of any series or class of shares of any party or shareholders of any party against any party or any member, trustee, officer, manager (including The RMR Group LLC or its successor), agent or employee of any party, including disputes, claims or controversies relating to the meaning, interpretation, effect, validity, performance or enforcement of this Agreement, including this arbitration provision, or the declarations of trust, limited liability company agreements, charters, bylaws or other governing documents of any party hereto (all of which are referred to as “Disputes”), or relating in any way to such a Dispute or Disputes shall, on the demand of any party to such Dispute 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 11. For the avoidance of doubt, and not as a limitation, Disputes are intended to include derivative actions against trustees, officers or managers of any party and class actions by a shareholder against those individuals or entities and any 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 11, the term “party” shall include any direct or indirect parent of a party.

11.2 Selection of Arbitrators. There shall be three (3) arbitrators. If there are only two (2) parties to the Dispute, each party shall select one arbitrator within fifteen (15) days after receipt of a demand for arbitration. Such arbitrators may be affiliated or interested persons of such 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 arbitrator within fifteen (15) days after receipt of a demand for arbitration. Such 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 to timely select an arbitrator then the party (or parties) who has selected an arbitrator may request the 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 the AAA provides such list to select one of the three (3) arbitrators proposed by AAA. If such party (or parties) fail to select such arbitrator by such time, the party (or parties) who have appointed the first arbitrator shall then have ten (10) days to select one of the three (3) arbitrators proposed by AAA to be the second arbitrator; and, if he/they should fail to select such arbitrator by such time, the AAA shall select, within fifteen (15) days thereafter, one of the three (3) arbitrators it had proposed as the second arbitrator. The two (2) arbitrators so appointed shall jointly appoint the third and presiding arbitrator (who shall be neutral, impartial and unaffiliated with any party) within fifteen (15) days of the appointment of the second arbitrator. If the third

12

arbitrator has not been appointed within the time limit specified herein, then the AAA shall provide a list of proposed arbitrators in accordance with the Rules, and the arbitrator shall be appointed by the AAA in accordance with a listing, striking and ranking procedure, with each party having a limited number of strikes, excluding strikes for cause.

11.3 Location of Arbitration. The place of arbitration shall be Boston, Massachusetts unless otherwise agreed by the parties.

11.4 Scope of Discovery. There shall be only limited documentary discovery of documents directly related to the issues in dispute, as may be ordered by the arbitrators.

11.5 Arbitration Award. In rendering an award or decision (the “Arbitration Award”), the arbitrators shall be required to follow the laws of the State of Maryland. Any arbitration proceedings or Arbitration Award rendered hereunder and the validity, effect and interpretation of this arbitration provision shall be governed by the Federal Arbitration Act, 9 U.S.C. §1 et seq. The Arbitration Award shall be in writing and may, but shall not be required to, briefly state the findings of fact and conclusions of law on which it is based.

11.6 Costs. Except to the extent expressly provided by this Agreement or as otherwise agreed by the parties, 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 appointed arbitrator.

11.7 Final Judgment. An Arbitration Award shall be final and binding upon the parties thereto and shall be the sole and exclusive remedy between such parties relating to the Dispute, including any claims, counterclaims, issues or accounting presented to the arbitrators. Judgment upon the Arbitration 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.

11.8 Payment. Any monetary award shall be made and payable in U.S. dollars free of any tax, deduction or offset. Each party against which the Arbitration Award assesses a monetary obligation shall pay that obligation on or before the thirtieth (30th) day following the date of the Arbitration Award or such other date as the Arbitration Award may provide.

11.9 Intended Beneficiaries. This Section 11 is intended to benefit and be enforceable by the shareholders, members, direct and indirect parents, trustees, directors, officers, managers (including The RMR Group LLC or its successor), agents or employees of any party and the parties and shall be binding on the shareholders of any party and the parties, as

13

applicable, and shall be in addition to, and not in substitution for, any other rights to indemnification or contribution that such individuals or entities may have by contract or otherwise.

Section 12. Miscellaneous.

(a) Tenant agrees that its obligations and the rights of the Secured Party hereunder and in respect of the Obligations may be enforced by specific performance hereof and thereof and by temporary, preliminary and/or final injunctive relief relating hereto and thereto, without necessity for proof by the Secured Party or any holder of the Obligations that it would otherwise suffer irreparable harm, and Tenant hereby consents to the issuance of such specific and injunctive relief.

(b) Any notice or demand upon Tenant or the Secured Party shall be deemed to have been sufficiently given when given in accordance with the provisions of Lease No. 5.

(c) None of the terms and conditions of this Agreement may be changed, waived, modified or varied in any manner whatsoever unless in writing duly signed by Tenant and the Secured Party. No notice to or demand on Tenant in any case shall entitle Tenant to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the Secured Party to any other or further action in any circumstances without notice or demand.

(d) The obligations of Tenant hereunder shall remain in full force and effect without regard to, and shall not be impaired by, (i) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or the like of Tenant; (ii) any exercise or non-exercise, or any waiver of, any right, remedy, power or privilege under or in respect of this Agreement, Lease No. 5 or any document or agreement executed in connection herewith or therewith, the Obligations or any security for any of the Obligations; or (iii) any amendment to or modification of any of Lease No. 5 or any document or agreement executed in connection herewith or therewith, the Obligations or any security for any of the Obligations; whether or not Tenant shall have notice or knowledge of any of the foregoing. The rights and remedies of the Secured Party herein provided for are cumulative and not exclusive of any rights or remedies which the Secured Party would otherwise have, including, without limitation, under Lease No. 5 or any document or agreement executed in connection herewith or therewith. This Agreement is intended as a supplement for and is not intended to supersede in any respect Lease No. 5 or any document or agreement executed in connection herewith or therewith.

(e) This Agreement shall be binding upon Tenant and its successors and assigns and shall inure to the benefit of the Secured Party, and its respective successors and assigns. All agreements, representations and warranties made herein shall survive the execution and delivery of this Agreement.

(f) The descriptive headings of the several sections of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

14

(g) Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibitions or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

(h) This Agreement shall be interpreted, construed, applied and enforced in accordance with the laws of the Commonwealth of Massachusetts applicable to contracts between residents of Massachusetts which are to be performed entirely within Massachusetts, regardless of (i) where this Agreement is executed or delivered; or (ii) where any payment or other performance required by this Agreement is made or required to be made; or (iii) where any breach of any provision of this Agreement occurs, or any cause of action otherwise accrues; or (iv) where any action or other proceeding is instituted or pending; or (v) the nationality, citizenship, domicile, principle place of business, or jurisdiction of organization or domestication of any party; or (vi) whether the laws of the forum jurisdiction otherwise would apply the laws of a jurisdiction other than the Commonwealth of Massachusetts; or (vii) any combination of the foregoing. Notwithstanding the foregoing, to the extent that matters of title, or creation, perfection and priority of the security interests created hereby, or procedural issues of foreclosures are required to be governed by the laws of the state in which the Collateral, or relevant part thereof, is located, the laws of such State shall apply.

Section 14. NON-LIABILITY OF TRUSTEES. THE DECLARATION OF TRUST ESTABLISHING THE SECURED PARTY, DATED NOVEMBER 10, 20014, AS AMENDED AND SUPPLEMENTED, AS FILED WITH THE STATE DEPARTMENT OF ASSESSMENTS AND TAXATION OF MARYLAND, PROVIDES THAT NO TRUSTEE, OFFICER, SHAREHOLDER, EMPLOYEE OR AGENT OF THE SECURED PARTY SHALL BE HELD TO ANY PERSONAL LIABILITY, JOINTLY OR SEVERALLY, FOR ANY OBLIGATION OF, OR CLAIM AGAINST, THE SECURED PARTY. ALL PERSONS DEALING WITH THE SECURED PARTY IN ANY WAY SHALL LOOK ONLY TO THE ASSETS OF THE SECURED PARTY FOR THE PAYMENT OF ANY SUM OR THE PERFORMANCE OF ANY OBLIGATION.

W I T N E S S E T H :

WHEREAS, [·], a [·], as landlord (“Landlord”), and Sublandlord, as tenant, are parties to that certain Master Lease Agreement (Lease No. 5), of even date herewith, as amended from time to time (as so amended, the “Lease”), pursuant to which Landlord leases to Sublandlord and Sublandlord leases from Landlord the Leased Property, as more particularly described in the Lease, which Leased Property includes that certain Property related to the parcel of land described on Exhibit A attached hereto and made a part hereof (the “Subleased Property”); and

WHEREAS, in connection with the execution and delivery of the Lease, Sublandlord wishes to sublease to Subtenant and Subtenant wishes to sublease from Sublandlord the Subleased Property as hereinafter provided;

NOW, THEREFORE, in consideration of the mutual covenants herein contained and other good and valuable consideration, the mutual receipt and legal sufficiency of which are hereby acknowledged, Sublandlord and Subtenant hereby agree as follows:

1. Defined Terms. Capitalized terms used and not otherwise defined herein shall have the meanings given such terms in the Lease.

2. Sublease. Upon and subject to the terms and conditions hereinafter set forth, Sublandlord hereby subleases to Subtenant, and Subtenant hereby subleases from Sublandlord, all of Sublandlord’s right, title and interest in, to, under and relating to the Subleased Property, including, without limitation, any leasehold rights of Sublandlord relating to the use or occupancy thereof.

3. Term. The term of this Sublease commences on the date hereof and shall expire simultaneously with the expiration or sooner termination of the term of the Lease with respect to the Subleased Property.

4. Rent. Commencing on the date hereof, Subtenant shall pay to Sublandlord, in accordance with the applicable terms and provisions of the Lease, all amounts due and payable by Sublandlord under the Lease with respect to the Subleased Property. The Minimum Rent shall be adjusted following any disbursement by Landlord with respect to the Subleased Property in accordance with Section 3.1.1(c) of the Lease, and Minimum Rent hereunder may be adjusted to reflect the allocation and reallocation of Minimum Rent among the Leased Property (including, without limitation, the Subleased Property) by agreement between Landlord and Sublandlord in accordance with Section 3.1.1(b) of the Lease.

5. Incorporation of Lease. Article 12 of the Lease is hereby incorporated by reference except that “Landlord” shall be “Sublandlord” and “Tenant” shall be “Subtenant”; and Section 16.2 of the Lease is incorporated herein by reference. Subtenant shall be liable to Sublandlord for any damages Sublandlord incurs under the Lease or any Incidental Document as a direct or indirect result of breach of any of Subtenant’s obligations under this Sublease. Subtenant shall observe and perform for the benefit of Sublandlord all of the terms, covenants and conditions of the Lease which Sublandlord, as tenant under the Lease, is obligated to observe and perform with respect to the Subleased Property for the benefit of Landlord including complying with and performing the obligations in Sections 5.3 and 21.1 through 21.5 of the Lease as if Subtenant were “Tenant” described therein, except that the first sentence of Section 21.2 of the Lease shall not apply to Subtenant.

6. No Assignment or Subletting. Subtenant shall not assign or sublease, directly or indirectly, the Subleased Property without the prior consent of Sublandlord and otherwise in accordance with the applicable terms and conditions of the Lease; provided, however, that the foregoing shall not be deemed to prohibit Subtenant from permitting patients or residents to occupy the Facility located on the Subleased Property in the ordinary course of Subtenant’s business and in accordance with the applicable terms and conditions of the Lease.

7. Arbitration.

4. Guarantee. Each Subtenant Guarantor hereby unconditionally guarantees that the Guaranteed Obligations which are monetary obligations shall be paid in full when due and payable, whether upon demand, at the stated or accelerated maturity thereof pursuant to any Lease No. 5 Document, or otherwise, and that the Guaranteed Obligations which are performance obligations shall be fully performed at the times and in the manner such performance is required by the Lease No. 5 Documents. With respect to the Guaranteed Obligations which are monetary obligations, this guarantee is a guarantee of payment and not of collectability and is absolute and in no way conditional or contingent. In case any part of the Guaranteed Obligations shall not have been paid when due and payable or performed at the time performance is required, the Subtenant Guarantors shall, in the case of monetary obligations, within five (5) Business Days after receipt of notice from Landlord, pay or cause to be paid to Landlord the amount thereof as is then due and payable and unpaid (including interest and other charges, if any, due thereon through the date of payment in accordance with the applicable provisions of the Lease No. 5 Documents) or, in the case of non-monetary obligations, perform or cause to be performed such obligations in accordance with the Lease No. 5 Documents.

The Landlord shall promptly notify such Subtenant Guarantor of any such set-off made by Landlord and the application made by Landlord of the proceeds thereof.

6. Unenforceability of Guaranteed Obligations, Etc. If Tenant is for any reason under no legal obligation to discharge any of the Guaranteed Obligations (other than because the same have been previously discharged in accordance with the terms of the Lease No. 5 Documents), or if any other moneys included in the Guaranteed Obligations have become unrecoverable from Tenant by operation of law or for any other reason, including, without limitation, the invalidity or irregularity in whole or in part of any Guaranteed Obligation or of any Lease No. 5 Document or any limitation on the liability of Tenant thereunder not contemplated by the Lease No. 5 Documents or any limitation on the method or terms of payment thereunder which may now or hereafter be caused or imposed in any manner whatsoever, the guarantees contained in this Guaranty shall nevertheless remain in full force and effect and shall be binding upon each Subtenant Guarantor to the same extent as if such Subtenant Guarantor at all times had been the principal debtor on all such Guaranteed Obligations.

7. Additional Guarantees. This Guaranty shall be in addition to any other guarantee or other security for the Guaranteed Obligations and it shall not be prejudiced or rendered unenforceable by the invalidity of any such other guarantee or security or by any waiver, amendment, release or modification thereof.

4

8. Consents and Waivers, Etc. Each Subtenant Guarantor hereby acknowledges receipt of correct and complete copies of each of the Lease No. 5 Documents, and consents to all of the terms and provisions thereof, as the same may be from time to time hereafter amended or changed in accordance with the terms and conditions thereof, and, except as otherwise provided herein, to the maximum extent permitted by applicable law, waives (a) presentment, demand for payment, and protest of nonpayment, of any principal of or interest on any of the Guaranteed Obligations, (b) notice of acceptance of this Guaranty and of diligence, presentment, demand and protest, (c) notice of any default hereunder and any default, breach or nonperformance or Event of Default under any of the Guaranteed Obligations or the Lease No. 5 Documents, (d) notice of the terms, time and place of any private or public sale of any collateral held as security for the Guaranteed Obligations, (e) demand for performance or observance of, and any enforcement of any provision of, or any pursuit or exhaustion of rights or remedies against Tenant or any other guarantor of the Guaranteed Obligations, under or pursuant to the Lease No. 5 Documents, or any agreement directly or indirectly relating thereto and any requirements of diligence or promptness on the part of the holders of the Guaranteed Obligations in connection therewith, and (f) to the extent such Subtenant Guarantor lawfully may do so, any and all demands and notices of every kind and description with respect to the foregoing or which may be required to be given by any statute or rule of law and any defense of any kind which it may now or hereafter have with respect to this Guaranty, or any of the Lease No. 5 Documents or the Guaranteed Obligations (other than that the same have been discharged in accordance with the Lease No. 5 Documents).

9. No Impairment, Etc. The obligations, covenants, agreements and duties of each of the Subtenant Guarantors under this Guaranty shall not be affected or impaired by any assignment or transfer in whole or in part of any of the Guaranteed Obligations without notice to each such Subtenant Guarantor, or any waiver by Landlord or any holder of any of the Guaranteed Obligations or by the holders of all of the Guaranteed Obligations of the performance or observance by Tenant or any other guarantor of any of the agreements, covenants, terms or conditions contained in the Guaranteed Obligations or the Lease No. 5 Documents or any indulgence in or the extension of the time for payment by Tenant or any other guarantor of any amounts payable under or in connection with the Guaranteed Obligations or the Lease No. 5 Documents or any other instrument or agreement relating to the Guaranteed Obligations or of the time for performance by Tenant or any other guarantor of any other obligations under or arising out of any of the foregoing or the extension or renewal thereof (except that with respect to any extension of time for payment or performance of any of the Guaranteed Obligations granted by Landlord or any other holder of such Guaranteed Obligations to Tenant, such Subtenant Guarantor’s obligations to pay or perform such Guaranteed Obligation shall be subject to the same extension of time for performance), or the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of Tenant or any other guarantor set forth in any of the foregoing, or the voluntary or involuntary sale or other disposition of all or substantially all of the assets of Tenant or any other guarantor or insolvency, bankruptcy, or other similar proceedings affecting Tenant or any other guarantor or any assets of Tenant or any such other guarantor, or the release or discharge of Tenant or any such other guarantor from the performance or observance of any agreement, covenant, term or condition contained in any of the foregoing without the consent of the holders of the Guaranteed Obligations by operation of law, or any other cause, whether similar or dissimilar to the foregoing.

5

10. Reimbursement, Subrogation, Etc. Each Subtenant Guarantor hereby covenants and agrees that it will not enforce or otherwise exercise any rights of reimbursement, subrogation, contribution or other similar rights against Tenant (or any other person against whom Landlord may proceed) with respect to the Guaranteed Obligations prior to the payment in full of all amounts owing with respect to Lease No. 5, and until all indebtedness of Tenant to Landlord shall have been paid in full, no Subtenant Guarantor shall have any right of subrogation, and each Subtenant Guarantor waives any defense it may have based upon any election of remedies by Landlord which destroys its subrogation rights or its rights to proceed against Tenant for reimbursement, including, without limitation, any loss of rights such Subtenant Guarantor may suffer by reason of any rights, powers or remedies of Tenant in connection with any anti-deficiency laws or any other laws limiting, qualifying or discharging the indebtedness to Landlord. Until all obligations of Tenant pursuant to the Lease No. 5 Documents shall have been paid and satisfied in full, each Subtenant Guarantor further waives any right to enforce any remedy which Landlord now has or may in the future have against Tenant, any other guarantor or any other person and any benefit of, or any right to participate in, any security whatsoever now or in the future held by Landlord.

11. Defeasance. This Guaranty shall terminate at such time as the Guaranteed Obligations have been paid and performed in full and all other obligations of the Subtenant Guarantors to Landlord under this Guaranty have been satisfied in full; provided, however, if at any time, all or any part of any payment applied on account of the Guaranteed Obligations is or must be rescinded or returned for any reason whatsoever (including, without limitation, the insolvency, bankruptcy or reorganization of Tenant), this Guaranty, to the extent such payment is or must be rescinded or returned, shall be deemed to have continued in existence notwithstanding any such termination.

15.1 Disputes. Any disputes, claims or controversies between the parties (a) arising out of or relating to this Guaranty, or (b) brought by or on behalf of any shareholder of any party or a direct or indirect parent of a party (which, for purposes of this Section 15, shall mean any shareholder of record or any beneficial owner of shares of any party, or any former shareholder of record or beneficial owner of shares of any party), either on his, her or its own behalf, on behalf of any party or on behalf of any series or class of shares of any party or shareholders of any party against any party or any member, trustee, officer, manager (including The RMR Group LLC or its successor), agent or employee of any party, including disputes, claims or controversies relating to the meaning, interpretation, effect, validity, performance or enforcement of this Guaranty, including this arbitration provision, or the declarations of trust, limited liability company agreements, charters, bylaws or other governing documents of any party hereto (all of which are referred to as “Disputes”), or relating in any way to such a Dispute or Disputes shall, on the demand of any party to such Dispute 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 15. For the avoidance of doubt, and not as a limitation, Disputes are intended to include derivative actions against trustees, officers or managers of any party and class actions by a shareholder against those individuals or entities and any 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 15, the term “party” shall include any direct or indirect parent of a party.

15.2 Selection of Arbitrators. There shall be three (3) arbitrators. If there are only two (2) parties to the Dispute, each party shall select one arbitrator within fifteen (15) days after receipt of a demand for arbitration. Such arbitrators may be affiliated or interested persons of such 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 arbitrator within fifteen (15) days after receipt of a demand for arbitration. Such 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 to timely select an arbitrator then the party (or parties) who has selected an arbitrator may request the 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 the AAA provides such list to select one of the three (3) arbitrators proposed by AAA. If such party (or parties) fail to select such arbitrator by such time, the party (or parties) who have appointed the first arbitrator shall then have ten (10) days to select one of the three (3) arbitrators proposed by AAA to be the second arbitrator; and, if he/they should fail to select such arbitrator by such time, the AAA shall select, within fifteen (15) days thereafter, one of the three (3) arbitrators it had proposed as the second arbitrator. The two (2) arbitrators so appointed shall jointly appoint the third and presiding arbitrator (who shall be neutral, impartial and unaffiliated with any party) within fifteen (15) days of the appointment of the second arbitrator. If the third arbitrator has not been appointed within the time limit specified herein, then the AAA shall provide a list of proposed arbitrators in accordance with the Rules, and the arbitrator shall be appointed by the AAA in accordance with a listing, striking and ranking procedure, with each party having a limited number of strikes, excluding strikes for cause.

8

15.3 Location of Arbitration. The place of arbitration shall be Boston, Massachusetts unless otherwise agreed by the parties.

15.4 Scope of Discovery. There shall be only limited documentary discovery of documents directly related to the issues in dispute, as may be ordered by the arbitrators.

15.5 Arbitration Award. In rendering an award or decision (the “Arbitration Award”), the arbitrators shall be required to follow the laws of State of Maryland. Any arbitration proceedings or Arbitration Award rendered hereunder and the validity, effect and interpretation of this arbitration provision shall be governed by the Federal Arbitration Act, 9 U.S.C. §1 et seq. The Arbitration Award shall be in writing and may, but shall not be required to, briefly state the findings of fact and conclusions of law on which it is based.

15.6 Costs. Except to the extent expressly provided by this Guaranty or as otherwise agreed by the parties, 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 appointed arbitrator.

15.7 Final Judgment. An Arbitration Award shall be final and binding upon the parties thereto and shall be the sole and exclusive remedy between such parties relating to the Dispute, including any claims, counterclaims, issues or accounting presented to the arbitrators. Judgment upon the Arbitration 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.

15.8 Payment. Any monetary award shall be made and payable in U.S. dollars free of any tax, deduction or offset. Each party against which the Arbitration Award assesses a monetary obligation shall pay that obligation on or before the thirtieth (30th) day following the date of the Arbitration Award or such other date as the Arbitration Award may provide.

15.9 Intended Beneficiaries. This Section 15 is intended to benefit and be enforceable by the shareholders, members, direct and indirect parents, trustees, directors, officers, managers (including The RMR Group LLC or its successor), agents or employees of any party and the parties and shall be binding on the shareholders of any party and the parties, as applicable, and shall be in addition to, and not in substitution for, any other rights to indemnification or contribution that such individuals or entities may have by contract or otherwise.

16. Modification of Agreement. No modification or waiver of any provision of this Guaranty, nor any consent to any departure by any of the Subtenant Guarantors therefrom, shall

9

in any event be effective unless the same shall be in writing and signed by Landlord, and such modification, waiver or consent shall be effective only in the specific instances and for the purpose for which given. No notice to or demand on any Subtenant Guarantor in any case shall entitle such Subtenant Guarantor to any other or further notice or demand in the same, similar or other circumstances. This Guaranty may not be amended except by an instrument in writing executed by or on behalf of the party against whom enforcement of such amendment is sought.

17. Waiver of Rights by Landlord. Neither any failure nor any delay on Landlord’s part in exercising any right, power or privilege under this Guaranty shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise or the exercise of any other right, power or privilege.

18. Severability. In case any one or more of the provisions contained in this Guaranty should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, but this Guaranty shall be reformed and construed and enforced to the maximum extent permitted by applicable law.

19. Entire Contract. This Guaranty constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and shall supersede and take the place of any other instruments purporting to be an agreement of the parties hereto relating to the subject matter hereof.

20. Headings; Counterparts. Headings in this Guaranty are for purposes of reference only and shall not limit or otherwise affect the meaning hereof. This Guaranty may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument, and in pleading or proving any provision of this Guaranty, it shall not be necessary to produce more than one of such counterparts.

21. Remedies Cumulative. No remedy herein conferred upon Landlord is intended to be exclusive of any other remedy, and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or by statute or otherwise.

22. NON-LIABILITY OF TRUSTEES. THE DECLARATION OF TRUST ESTABLISHING LANDLORD, DATED NOVEMBER 10, 2004, AS AMENDED AND SUPPLEMENTED, AS FILED WITH THE STATE DEPARTMENT OF ASSESSMENTS AND TAXATION OF MARYLAND, PROVIDES THAT NO TRUSTEE, OFFICER, SHAREHOLDER, EMPLOYEE OR AGENT OF LANDLORD SHALL BE HELD TO ANY PERSONAL LIABILITY, JOINTLY OR SEVERALLY, FOR ANY OBLIGATION OF, OR CLAIM AGAINST, LANDLORD. ALL PERSONS DEALING WITH LANDLORD IN ANY WAY SHALL LOOK ONLY TO THE ASSETS OF LANDLORD FOR THE PAYMENT OF ANY SUM OR THE PERFORMANCE OF ANY OBLIGATION.

Each Subtenant authorizes the Secured Party to file any such financing statements without the signature of such Subtenant and such Subtenant will pay all applicable filing fees and related expenses.

No delay or omission on the part of the Secured Party or any holder of Obligations in exercising any right hereunder shall operate as a waiver of such right or of any other right hereunder. No waiver of any such right on any one occasion shall be construed as a bar to or waiver of any such right on any future occasion. No course of dealing between any Subtenant and the Secured Party or any holder of Obligations, nor any failure to exercise, nor any delay in exercising, on the part of the Secured Party or any holder of Obligations, any right, power or privilege hereunder or under any of the Obligations, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof, or the exercise of any other right, power or privilege.

The Secured Party shall not be required to marshal any present or future security for (including without limitation this Agreement and the Collateral pledged hereunder), or guaranties of, the Obligations or any of them, or to resort to such security or guaranties in any particular order; and all of the rights hereunder and in respect of such securities and guaranties shall be

11

cumulative and in addition to all other rights, however existing or arising. To the maximum extent permitted by applicable law, each Subtenant hereby agrees that it will not invoke any law relating to the marshalling of collateral, which might cause delay in or impede the enforcement of the Secured Party’s rights under this Agreement or under any other instrument evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or guaranteed, and, to the maximum extent permitted by applicable law, each Subtenant hereby irrevocably waives the benefits of all such laws.
