under the Exchange Act, and in either case a successor depositary shall not have been appointed by the Company within 90 days after
such notice is received by the Company or the Company becomes aware of such cessation, respectively, or (ii) there shall have occurred
and be continuing an Event of Default with respect to such Global Note and the Security Registrar has received a written request
from an owner of beneficial interest in such Global Note to receive registered Notes. In any such case, the Company will issue
individual Notes in exchange for such Global Note representing such Notes in authorized denominations.


 


Notwithstanding any provisions
of Section 2.1(e) or Section 2.1(f) of this Supplemental Indenture to the contrary, payments of principal, premium,
if any, and interest on any Global Note shall be made in accordance with the procedures of the Depositary and its participants
in effect from time to time.


 


(e)              
Interest and Interest Rate. The Notes will bear interest at a rate of 9.750% per annum, from June 2, 2020
(or, in the case of Notes issued after June 2, 2020, from the date designated by the Company in connection with such issuance),
or from the immediately preceding Interest Payment Date to which interest has been paid or duly provided for, payable semi-annually
in arrears on June 15 and December 15 of each year, commencing December 15, 2020 (each of which shall be an “Interest
Payment Date”), or if such day is not a Business Day, on the next succeeding Business Day, to the Persons in whose names
the Notes are registered in the Security Register at the close of business on the Regular Record Date for such interest, which
shall be June 1 or December 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date (each,
a “Regular Record Date”).


 


(f)                Principal
Repayment; Currency. The Stated Maturity of the principal of the Notes is June 15, 2025; provided, however, the Notes may
be earlier redeemed at the option of the Company as provided in Section 2.1(g) of this Supplemental Indenture and
the Company may be obligated to repurchase the Notes prior to the Stated Maturity of the principal of the Notes as provided
in Section 3.1(f) of this Supplemental Indenture. The principal of each Note payable at its Maturity shall be paid
against presentation and surrender thereof at the Corporate Trust Office, in such coin or currency of the United States of
America as at the time of payment is legal tender for the payment of public or private debts.


 


(g)               Redemption
at the Option of the Company. The Notes will be subject to redemption (pursuant to the terms of this Section 2.1(g)) in
whole at any time or in part from time to time before they mature at the option of the Company upon not less than 15 nor more
than 60 days’ notice to each Holder of Notes to be redeemed at its address appearing in the Security Register, or, in
the case of any Global Note, in accordance with the procedures of the Depositary and its participants in effect from time to
time. On and after June 15, 2022, the Company may redeem the Notes at its option, in
whole or from time to time in part, at the following Redemption Prices (expressed as a percentage of principal amount) plus
accrued and unpaid interest, if any, on the Notes being redeemed to, but not including, the applicable Redemption Date, if
redeemed during the twelve-month period beginning on June 15 of the years indicated below:

amount thereof) of 109.750% plus accrued and unpaid interest, if any, to, but not including, the applicable Redemption Date;
provided that


 


(i)              
at least 50% of the original aggregate principal amount of the Notes (including the original aggregate principal
amount of any Additional Notes) remains outstanding after each such redemption; and


 


(ii)             
the Redemption Date occurs within 90 days after the closing of such Equity Offering (for purposes of clarity, in
the event that there are two or more closings for any Equity Offering, then each such closing shall be deemed a separate “closing”
for purposes of the foregoing provisions of this clause (ii) with respect to the securities issued at such closing).


 


In
addition, the Company may redeem the Notes at its option, in whole or from time to time in part, at any time prior to June 15,
2022, at a Redemption Price equal to the outstanding principal amount of the Notes
being redeemed, plus accrued and unpaid interest, if any, on the Notes being redeemed, to, but not including, the applicable Redemption
Date, plus the Make-Whole Amount, if any.


 


On or before 11:00
a.m. Eastern Time on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company

on such Redemption Date. If the Company instructs the Trustee in writing to send the notice of redemption in the name of and at
the expense of the Company as provided in Section 1104 of the Base Indenture, the Company shall provide the Trustee with
such written instruction at least five (5) Business Days (or such shorter time as the Trustee may agree) prior to the date such
notice of redemption is to be sent.

on such day will be due and payable on the next succeeding Business Day, and no interest will accrue thereon for the period from
and after such Interest Payment Date, Redemption Date, Change of Control Payment Date or Stated Maturity, as the case may be, through

ADDITIONAL COVENANTS


 


Section
3.1               Additional
Covenants. In addition to the covenants of the Company set forth in Article Eight and Article Ten of the Base Indenture, Holders
of the Notes shall have the benefit of the following covenants:


 


(a)              
Limitations on Incurrence of Debt.


 


(i)                
The Company will not, and will not permit any Subsidiary to, incur any Debt if, immediately after giving effect to
the incurrence of such additional Debt and the application of the proceeds therefrom, the aggregate principal amount of all outstanding
Debt of the Company and its Subsidiaries on a consolidated basis determined in accordance with generally accepted accounting principles
is greater than 60% of the sum of (without duplication):


 


(A)            
 the Total Assets of the Company and its Subsidiaries as of the end of the fiscal quarter covered by the Company’s
Annual Report on Form 10-K, or its Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission
(or, if such filing is not permitted or required under the Exchange Act, with the Trustee) prior to the incurrence of such additional
Debt; and


 


(B)             
the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering
proceeds received (to the extent that such proceeds were not used to acquire real estate assets or mortgages receivable or used
to reduce Debt), by the Company or any Subsidiary since the end of such fiscal quarter, including those proceeds obtained in connection
with the incurrence of such additional Debt.


 


For purposes of this Supplemental Indenture, “Adjusted
Total Assets” means the sum of (A) and (B) above.


 






    13


     


    

 


(ii)             
The Company will not, and will not permit any Subsidiary to, incur any Secured Debt if, immediately after giving
effect to the incurrence of such additional Secured Debt and the application of the proceeds therefrom, the aggregate principal
amount of all outstanding Secured Debt of the Company and its Subsidiaries on a consolidated basis determined in accordance with
generally accepted accounting principles is greater than 40% of Adjusted Total Assets.


 


(iii)           
The Company will not, and will not permit any Subsidiary to, incur any Debt if, immediately after giving effect to
the incurrence of such additional Debt and on a pro forma basis, including the application of the proceeds therefrom, the ratio
of Consolidated Income Available for Debt Service to the Annual Debt Service for the four consecutive fiscal quarters most recently
ended prior to the date on which such additional Debt is to be incurred is less than 1.5 to 1.0, calculated on the assumptions
that:


 


(A)            
such Debt and any other Debt incurred by the Company and its Subsidiaries on a consolidated basis since the first
day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Debt, had occurred
at the beginning of such period;


 


(B)             
the repayment, retirement or other discharge of any other Debt by the Company and its Subsidiaries on a consolidated
basis since the first day of such four-quarter period had occurred at the beginning of such period (except that, in making such
computation, the amount of Debt under any revolving credit facility shall be computed based upon the average daily balance of such
Debt during such period);


 


(C)             
in the case of Acquired Debt or Debt incurred in connection with or in contemplation of any acquisition, including
any Person becoming a Subsidiary, since the first day of such four-quarter period, the related acquisition had occurred as of the
first day of such period with appropriate adjustments with respect to such acquisition being included in such pro forma calculation;
and


 


(D)            
in the case of any acquisition or disposition by the Company and its Subsidiaries on a consolidated basis of any
asset or group of assets since the first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase
or sale, such acquisition or disposition or any related repayment of Debt had occurred as of the first day of such period with
the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation.


 


If the Debt
giving rise to the need to make the foregoing calculation or any other Debt incurred after the first day of the relevant four-quarter
period bears interest at a floating interest rate, then, for purposes of calculating the Annual Debt Service, the interest rate
on such Debt shall be computed on a pro forma basis as if the average interest rate which would have been in effect during the
entirety of such four-quarter period had been the applicable rate for the entirety of such period.


 






    14


     


    

 



 


(b)              
Maintenance of Total Unencumbered Assets. The Company and its Subsidiaries will at all times maintain Total
Unencumbered Assets of not less than 150% of the aggregate outstanding principal amount of the Unsecured Debt of the Company and
its Subsidiaries on a consolidated basis in accordance with generally accepted accounting principles.


 


(c)              
Provision of Financial Information. Whether or not the Company is subject to Section 13 or 15(d) of the Exchange
Act, it will, within 15 days after each of the respective dates by which it would have been required to file annual reports, quarterly
reports and other documents with the Commission if it were so subject, (1) transmit by mail to all Holders, as their names and
addresses appear in the Security Register, without cost to such Holders, copies of the annual reports, quarterly and other reports,
financial statements and other documents which it would have been required to file with the Commission pursuant to Section 13 or
15(d) of the Exchange Act, if it were subject to such Sections, (2) file with the Trustee copies of the annual reports, quarterly
or other reports, financial statements and other documents which it would have been required to file with the Commission pursuant
to Section 13 or 15(d) of the Exchange Act, if it was subject to such Sections, and (3) promptly upon written request and payment
of the reasonable cost of duplication and delivery, supply copies of such documents to any prospective Holder; provided that, the
foregoing requirements shall be deemed satisfied if the foregoing materials are available on the Commission’s EDGAR system
or on the Company’s website within the applicable time period. The Trustee shall have no liability or responsibility for
the filing, timeliness or content of any such reports, financial statements, documents or information filed by the Company and
delivery of such reports, financial statements, documents or information to the Trustee is for informational purposes only and
receipt of such shall not constitute constructive notice thereof or any information contained therein.


 


Notwithstanding the
foregoing, if at any time the Notes are guaranteed by any direct or indirect parent company of the Company, the Company may satisfy
its obligations under this Section 3.1(c) with respect to financial information relating to the Company by furnishing financial
information relating to such direct or indirect parent company; provided, however, that the same is accompanied by consolidating
information that explains in reasonable detail the differences between the information relating to such direct or indirect parent
company and any of its Subsidiaries other than the Company and its Subsidiaries, on the one hand, and the information relating
to the Company and its Subsidiaries on a standalone basis, on the other hand.


 


(d)              
Additional Subsidiary Guarantees. If at any time (i) any Subsidiary (whether existing at the Issue Date or
acquired or created after the Issue Date) becomes (including on the date of acquisition or creation) a Subsidiary that is not an
Excluded Subsidiary or a Foreign Subsidiary or (ii) any Subsidiary ceases to be an Excluded Subsidiary or a Foreign Subsidiary,
then the Company will cause such Subsidiary to execute and deliver to the Trustee, within thirty (30) days from the date such Subsidiary
became a Subsidiary that is not an Excluded Subsidiary or a Foreign Subsidiary or ceased to be an Excluded Subsidiary or a Foreign
Subsidiary, as the case may be, a supplemental indenture in a form reasonably satisfactory to the Trustee pursuant to which such
Subsidiary will fully and unconditionally guarantee the Notes, jointly and severally with all other Subsidiary Guarantors, and
deliver an Officer’s Certificate and Opinion of Counsel reasonably satisfactory to the Trustee.


 






    15 


     


    

 





The covenant in this
Section 3.1(d) will automatically and permanently terminate and the Company will be automatically and permanently released
from all its obligations under this Section 3.1(d) on and after the date that (a) the Notes have an Investment Grade Rating
from both Rating Agencies and one of such Investment Grade Ratings is a Mid-BBB Investment Grade Rating; and (b) no Default or
Event of Default has occurred and is continuing.


 


(e)              
Subsidiary Guarantor May Consolidate, Etc., Only on Certain Terms; Successor Substituted. A Subsidiary Guarantor
may not consolidate with or merge into any other Person or convey, transfer or lease all or substantially all of its properties
and assets to any other Person (other than the Company or another Subsidiary Guarantor), and a Subsidiary Guarantor may not permit
any other Person (other than the Company or another Subsidiary Guarantor) to consolidate with or merge into it, unless:


 


(i)                
either (1) the Subsidiary Guarantor is the surviving entity or (2) the Person formed by or surviving any such consolidation
or merger (if other than the Subsidiary Guarantor) or to which such conveyance, transfer or lease has been made is an entity organized
and validly existing under the laws of the United States, any state thereof or the District of Columbia and expressly assumes,
by a supplemental indenture executed and delivered to the Trustee, in form satisfactory to the Trustee, the Subsidiary Guarantor’s
obligations under its Subsidiary Guarantee and the Indenture;


 


(ii)             
immediately after giving effect to such transaction, and treating any indebtedness which becomes an obligation of
the Subsidiary Guarantor, any other Subsidiary or the Company as a result of such transaction as having been incurred by the Subsidiary
Guarantor, such Subsidiary or the Company at the time of such transaction, no Event of Default, and no event which, after notice
or lapse of time or both, would become an Event of Default shall have happened and be continuing; and


 


(iii)           
the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that
such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such
transaction, such supplemental indenture comply with this Section 3.1(e) and that all conditions precedent provided for in the
Indenture relating to such transaction have been complied with;


 


provided that this Section
3.1(e) shall not apply to a transaction pursuant to which such Subsidiary Guarantor shall be released from its obligations under
its Subsidiary Guarantee and the Indenture in accordance with Section 6.4 of this Supplemental Indenture.


 


Upon any consolidation of a Subsidiary
Guarantor with, or merger of a Subsidiary Guarantor into, any other Person or any conveyance, transfer or lease all or
substantially all of the properties and assets of a Subsidiary Guarantor in accordance with this Section 3.1(e), the
successor Person formed by such consolidation or into which such Subsidiary Guarantor is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, such
Subsidiary Guarantor under the Indenture with the same effect as if such successor Person had been named as a Subsidiary
Guarantor in the Indenture, and thereafter, except in the case of a lease, the predecessor Subsidiary Guarantor shall be
relieved of all obligations and covenants under the Indenture and its Subsidiary Guarantee.


 






    16 


     


    

 


(f)               
Repurchase of Notes upon Change of Control. If a Change of Control occurs, each Holder of Notes will have
the right to require the Company to repurchase some or all (in minimum principal amounts of $2,000 or an integral multiple of $1,000,
provided that the remaining principal amount of any Note repurchased in part must not be less than $2,000) of such Holder’s
Notes at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest, if any,
up to, but not including, the date of repurchase (the “Change of Control Payment”).


 


Within ten (10) Business
Days following a Change of Control, the Company will mail a notice to each Holder of Notes (with a copy to the Trustee) describing
the transaction or transactions that constitute, or are expected to constitute, the Change of Control and offering to repurchase
Notes on a specified date (the “Change of Control Payment Date”), at a purchase price equal to the Change of
Control Payment (the “Change of Control Offer”). The Change of Control Payment Date will be no earlier than
30 days and no later than 60 days from the date such notice is mailed (or in the case of Global Notes, given pursuant to applicable
procedures of the Depositary).


 


On the Change of Control
Payment Date, the Company will, to the extent lawful:


 


(i)                accept
for payment all Notes or portions thereof properly tendered and not withdrawn pursuant to the Change of Control Offer;


 


(ii)             
deposit with the Paying Agent for the Notes an amount equal to the Change of Control Payment in respect of all Notes
or portions thereof so accepted; and


 


(iii)           
deliver or cause to be delivered to the Trustee the Notes accepted and an Officer’s Certificate stating the
aggregate principal amount of all Notes purchased by the Company.


 


The Paying Agent for
the Notes will promptly mail to each Holder of Notes properly tendered (or in the case of Global Notes, will promptly pay to the
Depositary or its nominee) the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail to
each Holder a new Note in principal amount equal to any unpurchased portion of the Notes surrendered; provided that such
new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.


 


The Company will comply
with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations to the extent those laws
and regulations are applicable to any Change of Control Offer. If the provisions of any of the applicable securities laws or regulations
conflict with the provisions of this Section 3.1(f), the Company will comply with the applicable securities laws and regulations
and will not be deemed to have breached its obligations under this Section 3.1(f) by virtue of that compliance.


 






    17 


     


    

 


The Company will
not be obligated to make or consummate a Change of Control Offer if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth in this Section 3.1(f) applicable to a
Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of
Control Offer. In addition, the Company will not be obligated to make or consummate a Change of Control Offer with respect to
the Notes, if it has irrevocably elected to redeem all of the Notes under Section 2.1(g) of this Supplemental
Indenture and has not defaulted on its redemption obligations. Notwithstanding anything to the contrary contained herein, a
Change of Control Offer may be made in advance of a Change of Control, subject to one or more conditions precedent,
including, but not limited to, the consummation of such Change of Control. The Change of Control Payment Date may be delayed
until such time (including more than 60 days after the notice is mailed or delivered, including by electronic transmission)
as such Change of Control is consummated. The Company may rescind or amend the Change of Control Offer in the event that the
Company shall determine that the Change of Control will not occur by the Change of Control Payment Date, or by the Change of
Control Payment Date as so delayed. A Change of Control Offer made in advance of the Change of Control may be made at the
same time as consents are solicited with respect to an amendment, supplement or waiver of the Indenture. Prior to the occurrence of a Change of Control, the provisions of this Section 3.1(f) relating to the Company’s obligation
to make a Change of Control Offer may be waived or modified with the written consent of the Holders of a majority in principal
amount of the Notes then outstanding.

of a Change of Control Offer, on or after the Change of Control Payment Date (or Change of Control Payment Date as may be delayed,
as the case may be)), or

reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders
is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with

(e)              
modify any of the provisions of this Section, Section 513 or Section 1006, except to increase any such

failure to pay an aggregate principal amount exceeding $50,000,000 of such indebtedness when due and payable after the

SUBSIDIARY GUARANTEES


 


Section
6.1            Subsidiary
Guarantee. Subject to this Article 6, each of the Subsidiary Guarantors hereby, jointly and severally,
unconditionally guarantees on a senior unsecured basis to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the
Notes or the obligations of the Company under the Indenture or the Notes, that: (a) the principal of and interest on the
Notes shall be promptly paid in full when due, whether at Stated Maturity, upon redemption or repurchase, by acceleration or
otherwise, and interest on the overdue principal of, and overdue premium and interest on, the Notes, if any, if lawful, and
all other obligations of the Company to Holders of the Notes or the Trustee under the Indenture or the Notes shall be
promptly paid in full or promptly performed, as the case may be, all in accordance with the terms of the Indenture and the
Notes; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations,
that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal,
whether at Stated Maturity, upon redemption or repurchase, by acceleration or otherwise. Failing payment when due of any
amount so guaranteed or failing performance of any other obligation so guaranteed for whatever reason, each Subsidiary
Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. Each Subsidiary
Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.


 


Each
of the Subsidiary Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent
by any Holder of the Notes with respect to any provisions of the Indenture or the Notes, the release of any other Subsidiary Guarantor,
the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. Each Subsidiary Guarantor hereby waives, to the
extent permitted by applicable law, diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency
or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever
and covenant that this Subsidiary Guarantee shall not be discharged except by complete performance of the obligations contained
in the Notes and the Indenture.


 






    24 


     


    

 


Unless and until released with
respect to any Subsidiary Guarantor in accordance with Section 6.4 of this Supplemental Indenture, this Subsidiary Guarantee
shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for
liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or
should a custodian, trustee, liquidator or other similar official be appointed for all or any part of the Company’s
assets. If any Holder of the Notes or the Trustee is required by any court or governmental authority or is otherwise required
to return to the Company, any Subsidiary Guarantor or any custodian, trustee, liquidator or other similar official acting in
relation to the Company or such Subsidiary Guarantor, any amount paid by the Company or such Subsidiary Guarantor to the
Trustee or such Holder, the Notes and this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in
full force and effect. Each Subsidiary Guarantor further agrees (to the fullest extent permitted by law) that, as between it,
on the one hand, and the Holders of the Notes and the Trustee, on the other hand, (a) subject to this Article 6, the
maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five of the Base Indenture, as
supplemented by this Supplemental Indenture, for the purposes of this Subsidiary Guarantee, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the
event of any acceleration of such obligations as provided in such Article Five, such obligations (whether or not due
and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of this Subsidiary
Guarantee.


  


Section
6.2            Limitation
on Subsidiary Guarantor Liability. Each Subsidiary Guarantor, and by its acceptance
of Notes, each Holder of the Notes, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee
of such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for
purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or
state law to the extent applicable to any Subsidiary Guarantee. To effectuate the
foregoing intention, the Trustee, the Holders of the Notes and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of each Subsidiary Guarantor under its
Subsidiary Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities
of such Subsidiary Guarantor that are relevant under such laws, and after giving effect
to any collections from, rights to receive contribution from or payments made by or on behalf of any other Subsidiary Guarantor
in respect of the obligations of such other Subsidiary Guarantor under this Article
6, result in the obligations of such Subsidiary Guarantor under its Subsidiary
Guarantee and the Indenture not constituting a fraudulent transfer or conveyance under such
laws. Each Subsidiary Guarantor that makes a payment under its Subsidiary Guarantee
is entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount
based on the adjusted net assets of each Subsidiary Guarantor, so long as the exercise of such right does not impair the rights of the Holders of the Notes under this Subsidiary
Guarantee.


 


Section
6.3            Execution
and Delivery of Subsidiary Guarantee. To evidence its Subsidiary Guarantee set forth in Section 6.1 of this Supplemental
Indenture, each Subsidiary Guarantor hereby agrees that this Supplemental Indenture or a supplemental indenture entered into by
such Subsidiary Guarantor pursuant to Section 3.1(d) of this Supplemental Indenture, as the case may be, shall be executed on behalf
of such Subsidiary Guarantor by an officer or other authorized signatory of such Subsidiary Guarantor.


 


Each Subsidiary Guarantor
hereby agrees that its Subsidiary Guarantee set forth in Section 6.1 of this Supplemental Indenture shall remain in
full force and effect notwithstanding the absence of the endorsement of any notation of such Subsidiary Guarantee on the Notes.


 


If an officer or
other authorized signatory of any Subsidiary Guarantor whose signature is on this Supplemental Indenture or a supplemental
indenture entered into by such Subsidiary Guarantor pursuant to Section 3.1(d) of this Supplemental Indenture, as the case
may be, no longer holds that office or is no longer such an authorized signatory at the time the Trustee authenticates any
Note, the Subsidiary Guarantee of such Subsidiary Guarantor shall be valid nevertheless with respect to such Note.


 


The delivery of any
Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set
forth in the Indenture on behalf of the Subsidiary Guarantors.


 






    25 


     


    

 


Section
6.4            Release of
a Subsidiary Guarantor. The Subsidiary Guarantee of a Subsidiary Guarantor will automatically terminate and be released, all
other obligations of such Subsidiary Guarantor under the Indenture will automatically terminate and such Subsidiary Guarantor will
be automatically released from its obligations under its Subsidiary Guarantee and its other obligations under the Indenture:


 


(a)              
in the event of a sale or other disposition of all or substantially all of the properties or assets of such Subsidiary
Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction)
the Company or a Subsidiary;


 


(b)              
in the event of a sale or other disposition (including through merger or consolidation) of Capital Stock of such
Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary
and such Subsidiary Guarantor ceases to be a Subsidiary as a result of the sale or other disposition;


 


(c)              
upon such Subsidiary Guarantor becoming an Excluded Subsidiary or a Foreign Subsidiary;


 


(d)              
upon the satisfaction and discharge, Defeasance or Covenant Defeasance of the Notes in accordance with Article Four
or Article Thirteen of the Base Indenture;


 


(e)              
upon the liquidation or dissolution of such Subsidiary Guarantor, provided no Default or Event of Default has occurred
that is continuing;


 


(f)               
upon the merger of such Subsidiary Guarantor into, or the consolidation of such Subsidiary Guarantor with, (a) a
Subsidiary if the surviving or resulting entity is an Excluded Subsidiary or a Foreign Subsidiary or (b) the Company or another
Subsidiary Guarantor; or


 


(g)              
on and after the date that (a) the Notes have an Investment Grade Rating from both Rating Agencies and one of such
Investment Grade Ratings is a Mid-BBB Investment Grade Rating; and (b) no Default or Event of Default has occurred and is continuing.


 


At the request of
the Company, and upon delivery to the Trustee of an Officers’ Certificate and an Opinion of Counsel each stating that
all conditions provided for in this Supplemental Indenture to the release of a Subsidiary Guarantor from its Subsidiary
Guarantee have been complied with (provided that the legal counsel delivering such Opinion of Counsel may rely as to matters
of fact on one or more Officer’s Certificates of the Company), the Trustee shall execute and deliver an appropriate
instrument evidencing such release (it being understood that the failure to obtain any such instrument shall not impair any
release pursuant to this Section 6.4).


 






    26 


     


    

 


Section
6.5            Benefits Acknowledged.
Each Subsidiary Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated
by this Supplemental Indenture and that the guarantee and waivers made by it pursuant to its Subsidiary Guarantee are knowingly
made in contemplation of such benefits.


 


Section
6.6            Waiver of
Subrogation. Until all of the Notes are discharged and paid in full, each Subsidiary Guarantor hereby irrevocably waives and
agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Company that arise from the
existence, payment, performance or enforcement of the Company’s obligations under the Notes or the Indenture and such Subsidiary
Guarantor’s obligations under this Subsidiary Guarantee and the Indenture, in any such instance including, without limitation,
any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim
or remedy of the Holders of the Notes against the Company, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly,
in cash or other assets or by set off or in any other manner, payment or security on account of such claim or other rights. If
any amount shall be paid to any Subsidiary Guarantor in violation of the preceding sentence and any amounts owing to the Trustee
or the Holders of the Notes under the Notes or the Indenture, shall not have been paid in full, such amount shall have been deemed
to have been paid to such Subsidiary Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Holders
of the Notes and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to
the obligations in favor of the Trustee or such Holders, as the case may be, whether matured or unmatured, in accordance with the
terms of the Indenture.


 


Section
6.7            Same Currency;
No Set Off. Each payment to be made by a Subsidiary Guarantor under
its Subsidiary Guarantee shall be payable in the currency in which corresponding payment obligations of the Company under the Notes
or the Indenture are denominated, and shall be made without set off, counterclaim, reduction or diminution of any kind or nature.


 


Section
6.8            Guarantee
Obligations Continuing. The obligations of each Subsidiary
Guarantor under the Indenture shall be continuing and shall remain in full force and effect until all such obligations have
been paid and satisfied in full. Each Subsidiary Guarantor agrees with the Trustee that, to the fullest extent permitted by
applicable law, it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability in such
form as counsel to the Trustee may reasonably request and as will prevent any action brought against it in respect of any
default under the Indenture being barred by any statute of limitations now or hereafter in force and, in the event of the
failure of a Subsidiary Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and agent of such
Subsidiary Guarantor to make, execute and deliver such written acknowledgment or acknowledgments or other instruments as may
from time to time become necessary or reasonably advisable, in the judgment of the Trustee on the advice of counsel,
to fully maintain and keep in force the liability of such Subsidiary Guarantor under the Indenture.


 






    27 


     


    

 


Section
6.9            No Merger
or Waiver; Cumulative Remedies. To the fullest extent permitted by
applicable law, no Subsidiary Guarantee shall operate by way of merger of any of the obligations of a Subsidiary Guarantor under
any other agreement. To the fullest extent permitted by applicable law, no failure to exercise and no delay in exercising, on the
part of the Trustee or the Holders of the Notes, any right, remedy, power or privilege under the Indenture or the Notes, shall
operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or under
the Indenture or the Notes preclude any other or further exercise thereof or the exercise of any other right, remedy, power or
privilege. To the fullest extent permitted by applicable law, the rights, remedies, powers and privileges in the Indenture, the
Notes and any other document or instrument between a Subsidiary Guarantor and/or the Company and the Trustee and the Holders of
the Notes are cumulative and not exclusive of any rights, remedies, powers and privilege provided by law.


 


Section
6.10          Dealing with
the Company and Others. The Holders and the Trustee, without releasing, discharging, limiting or otherwise affecting in whole
or in part the obligations and liabilities of any Subsidiary Guarantor under the Indenture and without the consent of or notice
to any Subsidiary Guarantor, may to the fullest extent permitted by applicable law:


 


(a)           grant time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to
the Company or any other Person;


 


(b)           take or abstain from taking security or collateral from the Company or from perfecting security or collateral of
the Company;


 


(c)           release, discharge, compromise, realize, enforce or otherwise deal with or do any act or thing in respect of (with
or without consideration) any and all collateral, mortgages or other security given by the Company or any third party with respect
to the obligations or matters contemplated by the Indenture or the Notes;


 


(d)           accept compromises or arrangements from the Company;


 


(e)           apply all monies at any time received from the Company or from any security upon such part of the obligations of
the Subsidiary Guarantors under Section 6.1 of this Supplemental Indenture as the Holders may see fit or change any such application
in whole or in part from time to time as the Holders may see fit; and


 


(f)            otherwise deal with, or waive or modify their right to deal with, the Company and all other Persons and any security
as the Holders or the Trustee may see fit.


 


Section
6.11          Enforcement;
Expenses. If any Subsidiary Guarantor defaults in performing any of its obligations under the Indenture, the Trustee may proceed
in its name as trustee under the Indenture in the enforcement of such obligations against such Subsidiary Guarantor by any remedy
provided by law, whether by legal proceedings or otherwise. Each of the Subsidiary Guarantors, jointly and severally, agree to
pay all costs, fees and expenses (including, without limitation, reasonable fees and expenses of legal counsel) incurred by the
Trustee, any Holder of the Notes, or the agent, advisor or counsel of the Trustee or any Holder, in enforcing the performance by
any Subsidiary Guarantor of its obligations under the Indenture.

DIVERSIFIED HEALTHCARE TRUST


 


9.750%

	No. ____	$ ___________




 


Diversified Healthcare
Trust (formerly known as Senior Housing Properties Trust), a real estate investment trust duly organized and existing under the
laws of Maryland (herein called the “Company”, which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to _____________________________, or registered assigns, the
principal sum of ___________________ Dollars ($_____________) [(as the same may be revised from time to time on the Schedule of
Exchanges of Interests in the Global Security attached hereto)] on June 15, 2025, and to pay interest thereon from _________, 20__
or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on June 15 and
December 15 in each year, commencing _________, 20__ at the rate of 9.750% per annum,
until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one
or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall
be June 1 or December 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date
and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close
of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall
be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any
time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.


 


Payment of the principal
of (and premium, if any) and any such interest on this Security will be made at the office or agency of the Company maintained
for that purpose in such coin or currency of the United States of America as at the time of payment is legal tender for payment
of public and private debts or, in the case of any Note that is a Global Security, in accordance with the procedures of The Depository
Trust Company (“DTC”), or any successor depositary with respect to the Global Notes appointed under the Indenture,
the “Depositary”), and its participants in effect from time to time; provided, however, that at
the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.


 


Reference is hereby
made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.


 


Unless the certificate
of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

[Form of Reverse of Security]


 


1.       General.
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”),
issued and to be issued in one or more series under an Indenture, dated as of February 18, 2016 (the “Base Indenture”),
between the Company and U.S. Bank National Association (herein called the “Trustee”, which term includes any
successor trustee under the Base Indenture), as supplemented by a Third Supplemental Indenture, dated as of June 2, 2020 (as amended,
supplemented or otherwise modified from time to time, the “Supplemental Indenture” and the Base Indenture, as
supplemented by such Supplemental Indenture, the “Indenture”), among the Company, the Initial Subsidiary Guarantors
and the Trustee, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Subsidiary Guarantors, the Trustee, and the Holders of the Securities and
of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated
on the face hereof (such series, the “Notes”). Capitalized terms used but not defined herein have the meaning
given to them in the Indenture.


 


2.       Optional
Redemption. The Notes will be subject to redemption in whole at any time or in part from time to time before they mature at
the option of the Company upon not less than 15 nor more than 60 days’ notice by mail to each Holder of Notes to be redeemed
at its address appearing in the Security Register or, in the case of any Note that is a Global Security, in accordance with the
procedures of the Depositary and its participants in effect from time to time. On and after
June 15, 2022, the Company may redeem the Notes at its option, in whole or from time to time in part, at the following Redemption
Prices (expressed as a percentage of principal amount) plus accrued and unpaid interest, if any, on the Notes being redeemed to,
but not including, the Redemption Date, if redeemed during the twelve-month period beginning on June 15 of the years indicated
below:


 


	Year	 	Percentage	 
	2022	 	 	104.875	%
	2023	 	 	102.438	%
	2024 and thereafter	 	 	100.000	%



 


Prior to June
15, 2022, the Company may, at its option, on any one or more occasions, redeem up to 40% of the original aggregate principal
amount of Notes (including the original aggregate principal amount of any Additional Notes) with the Net Cash Proceeds of one or
more Equity Offerings at a Redemption Price (expressed as a percentage of the principal amount thereof) of 109.750% plus
accrued and unpaid interest, if any, to, but not including, the Redemption Date; provided that


 


(1) at least 50% of the original
aggregate principal amount of the Notes (including the original aggregate principal amount of any Additional Notes) remains outstanding
after each such redemption; and


 


(2) the Redemption Date occurs
within 90 days after the closing of such Equity Offering (for purposes of clarity, in the event that there are two or more closings
for any Equity Offering, then each such closing shall be deemed a separate “closing” for purposes of the foregoing
provisions of this clause (2) with respect to the securities issued at such closing).


 


In
addition, the Company may redeem the Notes at its option, in whole or from time to time in part, at any time prior to June 15,
2022, at a Redemption Price equal to the outstanding principal amount of the Notes being redeemed, plus accrued and unpaid
interest, if any, on the Notes being redeemed, to, but not including, the Redemption Date, plus the Make-Whole Amount, if any.


 


As used herein the term “Make-Whole
Amount” means, in connection with any redemption of any Note whose Redemption Price is to be determined by reference
to the Make-Whole Amount, the greater of:


 


		(1)	1.0% of the principal amount of such Note; and



 






    A-3


     


    

 


		(2)	the
                                         excess, if any, of (i) the aggregate present value as of the applicable Redemption
                                         Date of the Redemption Price of such Note that would apply if such Note were redeemed
                                         on June 15, 2022 (such Redemption Price
                                         (expressed as a percentage of principal amount) being set forth in the table above) and
                                         the amount of interest (exclusive of interest accrued to the Redemption Date) that would
                                         have been payable in respect of each dollar of principal of such Note being redeemed
                                         if such redemption had been made on June 15, 2022
                                         determined by discounting, on a semiannual basis, such Redemption Price and interest
                                         at the Reinvestment Rate (determined on the third Business Day preceding the date such
                                         notice of redemption relating to such redemption is given) from June
                                         15, 2022 (in the case of such Redemption Price) and, in the case of interest,
                                         from respective dates on which such interest would have been payable if such redemption
                                         had been made on June 15, 2022 over (ii) the
                                         aggregate principal amount of such Note being redeemed.



 


The Make-Whole Amount
shall be calculated by the Company and set forth in an Officer’s Certificate delivered to the Trustee, and the Trustee shall
be entitled to rely on said Officer’s Certificate.


 


As used herein the
term “Reinvestment Rate” means a rate per annum equal to the sum of 0.50% (fifty one hundredths of one percent)
plus the arithmetic mean of the yields on treasury securities at constant maturity displayed for each of the five most recent days
published in the Statistical Release under the caption “Treasury Constant Maturities” for the maturity (rounded to
the nearest month) corresponding to the remaining life to maturity (which, in the case of maturities corresponding to the principal
and interest due on the Notes at their maturity, shall be deemed to be June 15, 2022),
as of the Redemption Date of the principal being redeemed. If no maturity exactly corresponds to such maturity, yields for the
two published maturities most closely corresponding to such remaining life to maturity shall be calculated pursuant to the immediately
preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding
in each of such relevant periods to the nearest month. For purposes of calculating the Reinvestment Rate, the most recent Statistical
Release published prior to the date of determination of the Make-Whole Amount shall be used.


 


As used herein the
term “Statistical Release” means the statistical release designated “H.15” or any successor publication
which is published daily by the Federal Reserve System and which establishes yields on actively traded United States government
securities adjusted to constant maturities or, if such statistical release (or any successor publication) is not published at the
time of any determination under the Indenture, then any publicly available source of similar market data used for this purpose
in accordance with customary market practice which shall be designated by the Company.


 


The Company shall not
be required to make sinking fund or redemption payments with respect to the Notes. However, under certain circumstances in connection
with the occurrence of a Change of Control, the Company may be required to offer to the repurchase the Notes as provided for under
Section 3.1(f) of the Supplemental Indenture.


 


In the event of redemption
of this Security in part only, a new Note or Notes and of like tenor for the unredeemed portion hereof will be issued in the name
