3.2No Other Diligence.  The Purchaser acknowledges that, except as provided in Section 3.1, (i) the Purchaser has had the opportunity to fully investigate and inspect the physical and environmental condition of the Property, and to review and analyze all title examinations, surveys, environmental assessment reports, building evaluations, financial data and other investigations and materials pertaining to the Property which the Purchaser deems necessary to determine the feasibility of the Property and its decision to acquire the Property, (ii) the Purchaser shall not be conducting any further title

4

examinations, surveys, environmental assessments, building evaluations, financial analyses or other investigations with respect to the Property, and (iii) the Purchaser shall not have any right to terminate this Agreement as a result of any title examinations, surveys, environmental assessments, building valuations, financial analyses or other investigations with respect to the Property.

SECTION 9.APPORTIONMENTS.

9.1Real Property Apportionments.  (a)  The following items shall be apportioned at the Closing as of the close of business on the day immediately preceding the Closing Date:

(i)annual rents, operating costs, taxes and other fixed charges payable under the Leases;

(ii)percentage rents and other unfixed charges payable under the Leases;

(iii)fuel, electric, water and other utility costs;

(iv)municipal assessments and governmental license and permit fees;

(v)Real estate taxes and assessments other than special assessments, based on the rates and assessed valuation applicable in the fiscal year for which assessed;

(vi)Water rates and charges;

12

(vii)Sewer and vault taxes and rents; and

(viii)all other items of income and expense normally apportioned in sales of property in similar situations in the jurisdiction where the Property is located.

If any of the foregoing cannot be apportioned at the Closing because of the unavailability of the amounts which are to be apportioned, such items shall be apportioned on the basis of a good faith estimate by the parties and reconciled as soon as practicable after the Closing Date but, in any event, no later than one (1) year after the Closing Date.

(b)If there are water, gas or electric meters located at the Property, the Seller shall obtain readings thereof to a date not more than thirty (30) days prior to the Closing Date and the unfixed water rates and charges, sewer taxes and rents and gas and electricity charges, if any, based thereon for the intervening time shall be apportioned on the basis of such last readings.  If such readings are not obtainable by the Closing Date, then, at the Closing, any water rates and charges, sewer taxes and rents and gas and electricity charges which are based on such readings shall be prorated based upon the per diem charges obtained by using the most recent period for which such readings shall then be available.  Upon the taking of subsequent actual readings, the apportionment of such charges shall be recalculated and the Seller or the Purchaser, as the case may be, promptly shall make a payment to the other based upon such recalculations.  The parties agree to make such final recalculations within sixty (60) days after the Closing Date.

(c)If any refunds of real property taxes or assessments, water rates and charges or sewer taxes and rents shall be made after the Closing, the same shall be held in trust by the Seller or the Purchaser, as the case may be, and shall first be applied to the unreimbursed costs incurred in obtaining the same, then to any required refunds to tenants under the Leases, and the balance, if any, shall be paid to the Seller (for the period prior to the Closing Date) and to the Purchaser (for the period commencing with the Closing Date).

(d)If, on the Closing Date, the Property shall be or shall have been affected by any special or general assessment or assessments or real property taxes payable in

13

a lump sum or which are or may become payable in installments of which the first installment is then a charge or lien and has become payable, the Seller shall pay or cause to be paid at the Closing the unpaid installments of such assessments due and as of the Closing Date.

(e)No insurance policies of the Seller are to be transferred to the Purchaser, and no apportionment of the premiums therefor shall be made.

(f)At the Closing, the Seller shall transfer to the Purchaser the amount of all unapplied security deposits held pursuant to the terms of the Leases.

(g)Brokerage commissions, tenant improvement expenses and other amounts payable by the Seller as landlord under Leases entered into by the Seller after the date hereof, or in connection with the renewal or extension of any existing Lease, shall be allocated between the Seller and the Purchaser at Closing based upon their respective periods of ownership (calculated on a straight-line basis over the initial term or extension or renewal period, as applicable), and the Purchaser shall reimburse the Seller at the Closing for all amounts so allocated to the Purchaser and paid by the Seller prior to the Closing.  The Purchaser shall receive a credit at Closing for all unpaid brokerage commissions, tenant improvement expenses and other amounts payable by the Seller as landlord under any such new Lease, renewal or extension that are allocated to the Seller in accordance with the terms hereof.

(h)Amounts payable after the date hereof on account of capital expenditures under the 2011 capital expenditure budget previously prepared by the Seller (the “CapEx Budget”) (including, without limitation, budgeted items for “building improvements” and “development and redevelopment”), shall be allocated between the Seller and the Purchaser at Closing based upon their respective periods of ownership (on a straight line basis), and the Purchaser shall reimburse the Seller at the Closing for all amounts so allocated to the Purchaser and paid by the Seller prior to the Closing.  The Purchaser shall receive a credit at Closing for all unpaid amounts payable on account of capital expenditures under the CapEx Budget allocated to the Seller in accordance with the terms hereof.

(i)If a net amount is owed by the Seller to the Purchaser pursuant to this Section 9.1, such amount shall

14

be credited against the Purchase Price.  If a net amount is owed by the Purchaser to the Seller pursuant to this Section 9.1, such amount shall be added to the Purchase Price paid to the Seller.

(j)If, on the Closing Date, there are past due rents with respect to any Lease, amounts received by the Purchaser with respect to such Lease after the Closing Date shall be applied, first, to rents due or to become due during the calendar month in which the Closing occurs, and then, to all other rents due or past due in inverse order to the order in which they became due (i.e., first to arrearages most recently occurring, then to older arrearages).  Any such past due rents received by the Purchaser, once applied in the foregoing order of priority, to the extent applicable to the period prior to the Closing Date, shall be paid by the Purchaser to the Seller.  In no event shall the Seller have any right to take any action to collect any past due rents or other amounts following the Closing; provided, however, the Purchaser shall use commercially reasonable efforts to collect such past due rents and other amounts, except that the Purchaser shall have no obligation to institute any legal action or proceeding or otherwise enforce any of its rights and remedies under any Lease in connection with such commercially reasonable efforts.

12.13Arbitration.

(a)Any disputes, claims or controversies between the Seller and the Purchaser (i) arising out of or relating to this Agreement, or (ii) brought by or on behalf of any shareholder of the Seller or the Purchaser (which, for purposes of this Section 12.13, shall mean any shareholder of record or any beneficial owner of shares of the Seller

21

or the Purchaser, or any former shareholder of record or beneficial owner of shares of the Seller or the Purchaser), either on his, her or its own behalf, on behalf of the Seller or the Purchaser or on behalf of any series or class of shares of the Seller or the Purchaser or shareholders of the Seller or the Purchaser against the Seller or the Purchaser or any trustee, director, officer, manager (including Reit Management & Research LLC or its successor), agent or employee of the Seller or the Purchaser, including disputes, claims or controversies relating to the meaning, interpretation, effect, validity, performance or enforcement of this Agreement, including this arbitration agreement, the declaration of trust, limited liability company agreement, partnership agreement or analogous governing instruments, as applicable, of the Purchaser or the Seller, or the bylaws of the Purchaser or the Seller (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 12.13.  For the avoidance of doubt, and not as a limitation, Disputes are intended to include derivative actions against trustees, directors, officers or managers of the Seller or the Purchaser and class actions by a shareholder against those individuals or entities and the Seller or the Purchaser.  For the avoidance of doubt, a Dispute shall include a Dispute made derivatively on behalf of one party against another party.

(b)There shall be three arbitrators.  If there are only two parties to the Dispute (with, for purposes of this Section 12.13, any and all parties involved in the Dispute and owned by the same ultimate parent entity treated as one party), each party shall select one arbitrator within 15 days after receipt of a demand for arbitration.  Each party shall be entitled to appoint as its party appointed arbitrator an affiliated or interested person of such party.  If there are more than two 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 15 days after receipt of a demand for arbitration.  The respondents, on the one hand, and the claimants, on the other hand, shall each be entitled to

22

appoint as its party appointed arbitrator an affiliated or interested person of such party.  If either a claimant (or all claimants) or a respondent (or all respondents) fails 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 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 days from the date the AAA provides such list to select one of the three arbitrators proposed by AAA.  If such party (or parties) fails to select such arbitrator by such time, the party (or parties) who has appointed the first arbitrator shall then have ten days to select one of the three 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 15 days thereafter, one of the three arbitrators it had proposed as the second arbitrator.  The two arbitrators so appointed shall jointly appoint the third and presiding arbitrator (who shall be neutral, impartial and unaffiliated with any party) within 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.

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

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

(e)In rendering an award or decision (the “Award”), the arbitrators shall be required to follow the laws of the Commonwealth of Massachusetts.  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 may, but shall not be required to, briefly state the findings of fact and conclusions of law on which it is based.

23

(f)Except to the extent expressly provided by Section 12.2 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 the Seller’s or the Purchaser’s award to the claimant or the claimant’s attorneys.  Except to the extent expressly provided by Section 12.2 or as otherwise agreed by the parties, each party (or, if there are more than two 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 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.

(g)An 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 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.

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

(i)This Section 12.13 is intended to benefit and be enforceable by the shareholders, trustees, directors, officers, managers (including Reit Management & Research 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

24

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.

12.14Like Kind Exchange.  At either party’s request, the non-requesting party will take all actions reasonably requested by the requesting party in order to effectuate all or any part of the transactions contemplated by this Agreement as a forward or reverse like-kind exchange for the benefit of the requesting party in accordance with Section 1031 of the Internal Revenue Code and, in the case of a reverse exchange, Rev. Proc. 2000-37, including executing an instrument acknowledging and consenting to any assignment by the requesting party of its rights hereunder to a qualified intermediary or an exchange accommodation titleholder.  In furtherance of the foregoing and notwithstanding anything contained in this Agreement to the contrary, the requesting party may assign its rights under this Agreement to a “qualified intermediary” or an “exchange accommodation titleholder” in order to facilitate, at no cost or expense to the other, a forward or reverse like-kind exchange under Section 1031 of the Internal Revenue Code; provided, however, that such assignment will not relieve the requesting party of any of its obligations hereunder.  The non-requesting party will also agree to issue all closing documents, including the deed or other operative conveyance instrument, to the applicable qualified intermediary or exchange accommodation titleholder if so directed by the requesting party prior to Closing.  Notwithstanding the foregoing, in no event shall the non-requesting party incur or be subject to any liability that is not otherwise provided for in this Agreement.

12.15Recording.  This Agreement may not be recorded without the prior written consent of both parties.

12.16Non-liability of Trustees of Seller.  The Declaration of Trust establishing the Seller, dated September 12, 1996, 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 Seller shall be held to any personal liability, jointly or severally, for any obligation of, or claim against, the Seller.  All persons dealing with the Seller in any way shall look only to the assets of the Seller for the payment of any sum or the performance of any obligation.

12.17Non-liability of Trustees of Purchaser.  The Amended and Restated Declaration of Trust establishing Senior Housing Properties Trust, dated September 20, 1999, as amended and

25

supplemented, as filed with the State Department Of Assessments and Taxation of Maryland, provides that no trustee, officer, shareholder, employee or agent of Senior Housing Properties Trust shall be held to any personal liability, jointly or severally, for any obligation of, or claim against, Senior Housing Properties Trust.  All persons dealing with Senior Housing Properties Trust in any way shall look only to the assets of Senior Housing Properties Trust for the payment of any sum or the performance of any obligation.

12.18Waiver and Further Assurances.  The Purchaser hereby acknowledges that it is a sophisticated purchaser of real properties and that it is aware of all disclosures the Seller is or may be required to provide to the Purchaser in connection with the transactions contemplated hereby pursuant to any law, rule or regulation (including those of Massachusetts and those of the state in which the Property is located).  The Purchaser hereby acknowledges that, prior to the execution of this Agreement, the Purchaser has had access to all information necessary to acquire the Property and the Purchaser acknowledges that the Seller has fully and completely fulfilled any and all disclosure obligations with respect thereto.  The Purchaser hereby fully and completely discharges the Seller from any further disclosure obligations whatsoever relating to the Property.  In addition to the actions recited herein and contemplated to be performed, executed, and/or delivered by the Seller and the Purchaser, the Seller and the Purchaser agree to perform, execute and/or deliver or cause to be performed, executed and/or delivered at the Closing or after the Closing any and all such further acts, instruments, deeds and assurances as may be reasonably required to establish, confirm or otherwise evidence the Seller’s satisfaction of any disclosure obligations or to otherwise consummate the transactions contemplated hereby.
