There is hereby authorized one series of Securities, to be designated the "10.125% Junior Subordinated Debentures due June 15, 2041," in the initial aggregate principal amount of up to $29,639,200, subject to the right of the Company to reopen such series for issuances of additional securities of such series and except as -3- provided in Section 306 of the Base Indenture. The Debentures (together with the Trustee's certificate of authentication) shall be substantially in the form of Exhibit A hereto, which is hereby incorporated in and made a part of this Supplemental Indenture. 2.2. Stated Maturity. The Stated Maturity of the Debentures is June 15, 2041, provided, however, the Debentures may be earlier redeemed at the option of the Company as provided in Article III below. 2.3. Form and Payment; Minimum Transfer Restriction. (a) The Debentures shall be issued to the Property Trustee in fully registered definitive form without coupons in minimum denominations of $25 and integral multiples of $25 in excess thereof. Principal and interest on the Debentures issued in definitive form will be payable, the transfer of such Debentures will be registrable and such Debentures will be exchangeable for Debentures bearing identical terms and provisions at the Corporate Trust Office; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered holder at such address as shall appear in the Register. Notwithstanding the foregoing, so long as the registered holder of any Debentures is the Property Trustee, the payment of the principal of and interest (including Additional Interest and Additional Sums, if any) on such Debentures held by the Property Trustee will be made at such place, or by wire transfer of immediately available funds to such account, as may be designated by the Property Trustee. The Register for the Debentures shall be kept at the Corporate Trust Office, and the Trustee is hereby appointed registrar for the Debentures. (b) The Debentures may be transferred or exchanged only in minimum denominations of $25 and integral multiples of $25 in excess thereof, and any attempted transfer, sale or other disposition of Debentures in a denomination of less than $25 shall be deemed to be void and of no legal effect whatsoever, and any such transferee shall be deemed not to be the holder of such Debentures for any purpose, including but not limited to the receipt of payments in respect of such Debentures and such transferee shall be deemed to have no interest whatsoever in such Debentures. 2.4. Procedure for Distribution of Debentures to Holders of Trust Preferred Securities; Global Debenture; Depositary. If distributed to holders of Trust Preferred Securities pursuant to Section 9.4 of the Trust Agreement, the Debentures will be issued to such holders in the same form as the Trust Preferred Securities that such Debentures replace in accordance with the following procedures: (a) So long as Debentures are eligible for book-entry settlement with the Depositary, the Debentures will initially be issued in the form of one or more registered global securities without coupons ("Global Debentures") that will be deposited with, or on behalf of, a Depositary, who shall be the Depositary for the Trust Preferred Securities. Initially, the Depositary shall be The Depository Trust Company ("DTC"), or any successor Depositary for the Trust Preferred Securities, and the Global Debenture shall be registered in the name of DTC's nominee, Cede & Co. Except under the circumstance described below, the Debentures will not be issuable in definitive form. Unless and until it is exchanged in whole or in part for the individual Debentures represented thereby, a Global Debenture may not be transferred except as -4- a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any nominee of DTC to a successor depositary or any nominee of such successor. (b) So long as DTC or its nominee is the registered owner of a Global Debenture, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the Debentures represented by such Global Debenture for all purposes under this Supplemental Indenture. Except as described below, owners of beneficial interest in Debentures evidenced by a Global Debenture will not be entitled to have any of the individual Debentures represented by such Global Debenture registered in their names, will not receive or be entitled to receive physical delivery of any such Debentures in definitive form and will not be considered the owners or holders thereof under the Indenture or this Supplemental Indenture. (c) If DTC is at any time unwilling, unable or ineligible to continue as depositary and a successor depositary is not appointed by the Company within 90 days, the Company will issue individual Debentures in exchange for the Global Debenture or Global Debentures representing such Debentures. In addition, the Company may at any time and in its sole discretion, subject to certain limitations set forth in the Indenture, determine not to have any of such Debentures represented by one or more Global Debentures and, in such event, will issue individual Debentures in exchange for the Global Debenture or Global Debentures representing the Debentures. Individual Debentures so issued will be issued in denominations of $25 and integral multiples thereof. (d) If the Debentures are distributed to holders of the Trust Preferred Securities pursuant to the terms of the Trust Agreement, the Company will use its best efforts to list the Debentures on the New York Stock Exchange or such other stock exchange or other organization, if any, on which the Trust Securities are then listed. (e) Each Global Debenture shall bear substantially the following legend on the face thereof: UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 2.5. Interest. (a) Each Debenture will bear interest at the rate of 10.125% per annum (the "Coupon Rate") from and including June 21, 2001 until the principal thereof becomes due and payable, and will bear interest on any overdue principal at the Coupon Rate and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the Coupon Rate ("Additional Interest") until paid, compounded -5- quarterly, payable (subject to the provisions of Article IV) quarterly in arrears on the 15th day of September, December, March and June of each year (each, an "Interest Payment Date"), commencing on September 15, 2001 to the Person in whose name such Debenture is registered at the close of business on the Record Date next preceding such Interest Payment Date. The "Record Date" for payment of interest will be one Business Day before the Interest Payment Date, unless such Debenture is registered to a holder other than the Property Trustee or a nominee of the Depositary, in which case the Record Date for payment of interest will be the fifteenth calendar day before the applicable Interest Payment Date, whether or not a Business Day. Until liquidation, if any, of the Trust, each Debenture will be held in the name of the Property Trustee in trust for the benefit of the holders of the Trust Securities. (b) The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Debentures is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), with the same force and effect as if made on the date such payment was originally payable. 2.6. Applicability of Discharge, Defeasance and Covenant Defeasance Provisions. The Discharge and Covenant Defeasance provisions in Article Thirteen of the Base Indenture will apply to the Debentures. The Defeasance provisions in Article Thirteen of the Base Indenture will not apply to the Debentures. ARTICLE III REDEMPTION OF THE DEBENTURES 3.1. Tax Event or Investment Company Event Redemption. If a Tax Event or Investment Company Event (either a "Special Event") shall occur and be continuing, the Company may redeem the Debentures at any time within 180 days following the occurrence of that Special Event, in whole but not in part, at a redemption price (the "Special Event Redemption Price") equal to 100% of the principal amount of the Debentures plus accrued and unpaid interest thereon to the Redemption Date. 3.2. Optional Redemption by Company. The Company shall have the option to redeem the Debentures at any time on or after June 15, 2006, in whole or in part, at a redemption price (the "Optional Redemption Price") equal to 100% of the principal amount of the Debentures plus accrued and unpaid interest thereon to the Redemption Date. 3.3. Payment of Redemption Price if Preferred Securities are Book-entry. If the Preferred Securities are in book-entry-only form, in order for the Property Trustee to meet the obligation set forth in Section 4.2(d) of the Trust Agreement, the Company shall deposit with the Trustee an amount sufficient to pay the Special Event Redemption Price or the Optional Redemption Price, as the case may be, by 10:00 a.m., New York City time, on the date such Special Event Redemption Price or Optional Redemption Price, as the case may be, is to be paid. -6- ARTICLE IV EXTENSION OF INTEREST PAYMENT PERIOD 4.1. Extension of Interest Payment Period. (a) So long as no Event of Default under Section 501 of the Base Indenture (as supplemented by Section 6.1 of this Supplemental Indenture) has occurred and is continuing, the Company shall have the right, at any time during the term of the Debentures, from time to time to defer the payment of interest and Additional Sums, if any, by extending the interest payment period of such Debentures for a period not exceeding 20 consecutive quarters (an "Extension Period"). No Extension Period shall extend beyond the Stated Maturity of the Debentures. To the extent permitted by applicable law, accrued and unpaid interest and Additional Sums, the payment of which has been deferred because of an Extension Period imposed pursuant to this Section 4.1, will bear Additional Interest compounded quarterly. At the end of the Extension Period, the Company shall pay all interest then accrued and unpaid on the Debentures, including any Additional Interest and Additional Sums, if applicable, to the holders of the Debentures in whose names the Debentures are registered in the Register on the first Record Date preceding the end of the Extension Period. Before the termination of any Extension Period, the Company may elect to (i) shorten the Extension Period or (ii) further extend such Extension Period, provided that such period together with all such further extensions thereof shall not exceed 20 consecutive quarters, or extend beyond the Stated Maturity. At any time following the termination of any Extension Period and upon the payment of any accrued and unpaid Additional Interest and Additional Sums, if applicable, then due, the Company may elect to begin a new Extension Period, subject to the foregoing requirements. No interest or Additional Sums shall be due and payable during an Extension Period, except at the end thereof. (b) During any such Extension Period, the Company shall not (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of the Company's shares of beneficial interest, (ii) make any payment of principal of or interest or premium, if any, on, or repay, repurchase or redeem any indebtedness or debt securities of the Company that rank on a parity with or junior to the Debentures in right of payment or (iii) make any guarantee payments with respect to any guarantee by the Company of indebtedness or debt securities of any Subsidiary of the Company if such guarantee ranks on parity with or junior to the Debentures in right of payment (other than (A) dividends or distributions payable solely in Common Stock, (B) any reclassification of any class of the Company's shares of beneficial interest, (C) any declaration of a dividend in connection with the implementation of a plan of the Company providing for the issuance by the Company to all holders of its Common Stock of rights entitling the holders thereof to subscribe for or purchase shares of Common Stock or any class or series of preferred shares, which rights are (x) deemed to be transferred with such shares of Common Stock, (y) issued in respect of future issuances of Common Stock and (z) not exercisable until the occurrence of a specified event or events (a "Rights Plan"), (D) the issuance of any shares of beneficial interest of the Company under any Rights Plan or the redemption or repurchase of any rights distributed pursuant to a Rights Plan, (E) payments under the Guarantee relating to the Trust Preferred Securities, and (F) purchases of Common Stock issued under, or issued pursuant to rights issued under, any of the Company's benefit plans for its trustees, officers, employees, consultants or advisors or the directors, officers, employees, consultants or advisors of the Company's advisor). -7- 4.2. Notice of Extension. (a) If the Property Trustee is the only registered Holder of the Debentures at the time the Company elects to begin, shorten or extend an Extension Period, the Company shall give written notice to the Trust and the Trustee of its election to begin, shorten or extend any Extension Period on or before the earlier of (i) one Business Day before the Record Date for the next succeeding Interest Payment Date or (ii) subject to applicable law and stock exchange rules, the date the Trust is required to give notice of an Extension Period to the New York Stock Exchange or any other securities exchange or other applicable self-regulatory organization where the Trust Preferred Securities are then listed. The Company shall cause the Trust to give notice of the Company's election to begin, shorten or extend an Extension Period to the holders of such Trust Preferred Securities. (b) If the Property Trustee is not the only Holder of the Debentures at the time the Company elects to begin, shorten or extend an Extension Period, the Company shall give the Holders of the Debentures, the Regular Trustees and the Trustee written notice of its election to begin, shorten or extend such Extension Period at least 10 Business Days prior to the earlier of (i) the next succeeding Interest Payment Date or (ii) subject to applicable law and stock exchange rules, the date the Trust is required to give notice of an Extension Period to the New York Stock Exchange or any other securities exchange or other applicable self-regulatory organization where the Trust Preferred Securities are then listed. (c) The quarter in which any notice is given pursuant to paragraphs (a) or (b) of this Section 4.2 shall be counted as one of the 20 consecutive quarters permitted in the maximum Extension Period permitted under Section 4.1. ARTICLE V COVENANTS 5.1. Additional Covenants of the Company. In addition to the covenants of the Company set forth in Article Ten of the Base Indenture, for the benefit of the Holders of the Debentures: (a) The Company covenants and agrees (i) to maintain directly or indirectly 100% ownership of the Common Securities; provided that any successors or assigns of the Company permitted by the Base Indenture may succeed to the Company's ownership of the Common Securities, (ii) not to voluntarily terminate, wind-up or liquidate the Trust, except (A) in connection with a distribution of the Debentures to the holders of the Trust Preferred Securities in liquidation of the Trust or (B) in connection with any merger, consolidation or amalgamation of the Trust permitted by the Trust Agreement, and (iii) to use its reasonable efforts, consistent with the terms and provisions of the Trust Agreement, to cause the Trust to remain classified as a grantor trust for United States Federal income tax purposes. (b) The Company covenants and agrees that if and so long as (i) the Trustee is the Holder of all the Debentures on behalf of the Trust and (ii) the Company has elected, and has not revoked such election, to pay Additional Sums, the Company shall pay to the Trust the Additional Sums in respect of the Preferred Securities and Common Securities. -8- ARTICLE VI EVENTS OF DEFAULT 6.1. Events of Default. With respect to the Debentures issued under this Supplemental Indenture, Section 501 of the Base Indenture is hereby replaced in its entirety as follows: "Event of Default" means any one of the following events (whatever the reason for such Event of Default and whether or not it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (a) default in the payment of any interest upon the Debentures when such interest becomes due and payable, and continuance of such default for a period of 30 days, except during a during an Extension Period; or (b) default in the payment of the principal of the Debentures when they become due and payable at their Maturity; or (c) default in the performance of, or breach of, any covenant of the Company in the Indenture (other than a covenant a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has been expressly included in the Indenture solely for the benefit of a series of Securities other than the Debentures), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least a majority in principal amount of the Outstanding Debentures a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (d) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, or (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, or (e) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Company or any Significant Subsidiary in an involuntary case, (ii) appoints a Custodian of the Company or any Significant Subsidiary or for all or substantially all of either of its property, or (iii) orders the liquidation of the Company or any Significant Subsidiary, and the order or decree remains unstayed and in effect for 90 days. ARTICLE VII SUBORDINATION OF DEBENTURES Article Fourteen of the Base Indenture shall read as follows with respect to Debentures issued under this Supplemental Indenture: 14.1. Agreement to Subordinate. Each Holder of Debentures covenants and agrees by its acceptance thereof, that the obligation of the Company to make any payment on account of -9- the principal of and interest on the Debentures (the "Obligations") shall be subordinate and junior in right of payment to the Company's obligations to the holders of Senior Indebtedness of the Company. (a) In the case of any bankruptcy, insolvency, receivership, conservatorship, reorganization, readjustment of debt, marshaling of assets and liabilities or similar proceedings or any dissolution, liquidation or winding-up of or relating to the Company as a whole, whether voluntary or involuntary, all obligations of the Company due or to become due to holders of Senior Indebtedness of the Company shall be entitled to be paid in full, in cash or other permitted consideration, or otherwise provided for, before any payment of the Obligations shall be made by the Company. (b) In the event and during the continuation of any default beyond any grace period in the payment of principal of or interest on or any other monetary amounts due any Senior Indebtedness, or in the event that any event of default with respect to any Senior Indebtedness shall have occurred and be continuing and shall have resulted in such Senior Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured, waived or remedied or shall have ceased to exist and such acceleration shall have been rescinded or annulled or all amounts due on such Senior Indebtedness are paid in full in cash or other permitted consideration, or otherwise provided for, then no payment of the Obligations shall be made by the Company. 14.2. When Distribution Must be Paid Over. In the event that the Trustee or any Holder of Debentures receives from the Company any payment of any Obligations at a time when the Trustee or such Holder of Debentures, as applicable, has actual knowledge that such payment is prohibited by Section 14.1(a) or (b) hereof, such payment shall be held by the Trustee or such Holder of Debentures in trust for the benefit of, and shall be paid forthwith over and delivered upon written request to, the holders of Senior Indebtedness of the Company, as their interests may appear, or their agent, trustee or representative (a "Representative") under the indenture or other agreement (if any) pursuant to which Senior Indebtedness of the Company may have been issued, as their respective interests may appear, for application to the payment of all obligations with respect to Senior Indebtedness of the Company remaining unpaid to the extent necessary to pay such obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness of the Company. With respect to the holders of Senior Indebtedness of the Company, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article, and no implied covenants or obligations with respect to the holders of Senior Indebtedness of the Company shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Company, and shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of Holders of Debentures or the Company or any other Person money or assets to which any holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. -10- 14.3. Notice By Company. The Company shall promptly notify the Trustee of any facts known to the Company that would cause a payment of any Obligations to violate this Article, but failure to give such notice shall not affect the subordination of the Debentures to the Senior Indebtedness of the Company as provided in this Article. 14.4. Subrogation. After all obligations with respect to Senior Indebtedness of the Company are paid in full, and until the Debentures are paid in full, Holders of Debentures shall be subrogated to the rights of holders of Senior Indebtedness of the Company to receive distributions applicable to Senior Indebtedness of the Company to the extent that distributions otherwise payable to the Holders of Debentures have been applied to the payment of Senior Indebtedness of the Company. A distribution made under this Article to holders of Senior Indebtedness of the Company that otherwise would have been made to Holders of Debentures is not, as between the Company and Holders of Debentures, a payment by the Company on the Securities. 14.5. Relative Rights. This Article defines the relative rights of Holders of Debentures and holders of Senior Indebtedness of the Company. Nothing in this Indenture shall: (1) impair, as between the Company and Holders of Debentures, the obligation of the Company, which is absolute and unconditional, to pay principal of and interest on the Debentures in accordance with their terms; (2) affect the relative rights of Holders of Debentures and creditors of the Company other than their rights in relation to holders of Senior Indebtedness of the Company; or (3) prevent the Trustee or any Holder of Debentures from exercising its available remedies upon an Event of Default, subject to the rights of holders and owners of Senior Indebtedness of the Company to receive distributions and payments otherwise payable to Holders of Debentures.

Interest. Senior Housing Properties Trust, a Maryland real estate investment (the "Company") promises to pay interest on the principal amount of this Debenture at the rate and in the manner specified below. This Debenture will bear interest at the rate of 10.125% per annum (the "Coupon Rate") from and including June 21, 2001 until the principal thereof becomes due and payable, and will bear interest on any overdue principal at the Coupon Rate and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the Coupon Rate ("Additional Interest") until paid, compounded quarterly, payable (subject to the provisions of the Indenture) quarterly in arrears on the 15th day of September, December, March and June of each year (each, an "Interest Payment Date"), commencing on September 15, 2001 to the Person in whose name such Debenture is registered at the close of business on the Record Date next preceding such Interest Payment Date.
