In addition, the following terms shall have the following meanings with respect to this Twelfth Supplemental Indenture and the Notes to be equally applicable to both the singular and the plural forms of the terms set forth below:

“Adjusted EBITDA” means, for any period, the Issuer’s Pro Rata Share of EBITDA for such period; provided, that, so long as Shurgard Europe is not a Subsidiary of the Issuer, “Adjusted EBITDA” shall include the amount of dividends, distributions or interest paid in cash by any such entity that is not a Subsidiary to the Issuer or any of its Subsidiaries during the applicable period.

“Benchmark” means, initially, Compounded SOFR, as such term is defined below; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Issuer or its designee as of the Benchmark Replacement Date:

(1) the sum of: (a) an alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

(2) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

(3) the sum of: (a) the alternate rate of interest that has been selected by the Issuer or its designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Issuer or its designee as of the Benchmark Replacement Date:

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

The Notes shall initially be limited to an aggregate principal amount equal to $400,000,000, subject to the exceptions set forth in Section 301(2) of the Base Indenture and Section 1.4(e) hereof.

Section 1.3 Form of the Notes. The Notes will be issued in the form of one or more permanent fully registered global securities (the “Global Note”) that will be deposited with, or on behalf of the Depository, and registered in the name of the Depository or its nominee, as the case may be, subject to Section 305 of the Base Indenture. So long as the Depository, or its nominee, is the registered owner of the Global Note, the Depository or its nominee, as the case may be, will be considered the sole Holder of the Notes represented by the Global Note for all purposes under the Indenture.

Section 1.4 Terms and Provisions of the Notes. The Notes shall be governed by all of the terms and provisions of the Base Indenture, as supplemented by this Twelfth Supplemental Indenture, and in particular, the following provisions shall be terms of the Notes:

(a) Registration and Form. The Notes shall be issuable in registered form without coupons in minimum denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. Each Note shall be dated the date of its authentication and the Notes shall be substantially in the form of Exhibit A attached hereto.

12

(b) Payment of Principal and Interest. All payments of principal and interest in respect of the Global Notes will be made by the Issuer in immediately available funds to the Depository or its nominee, as the case may be, as the Holder of each of the Global Notes. The Notes shall mature, and the unpaid principal thereon, shall be payable, on July 25, 2025, subject to the provisions of the Base Indenture. Subject to Section 1.4(c), the per annum interest rate on the Notes in effect for each day of an Interest Period will be equal to Compounded SOFR, reset quarterly, plus 60 basis points (0.600%). Interest on the Notes will be payable quarterly in arrears on each January 25, April 25, July 25 and October 25, commencing October 25, 2023 (each, an “Interest Payment Date”) and on the Stated Maturity as specified in this Section 1.4(b), to the Persons in whose names the Notes are registered in the Security Register applicable to the Notes at the close of business on the fifteenth calendar day (whether or not a Business Day) immediately preceding each Interest Payment Date. If any Interest Payment Date would otherwise be a day that is not a Business Day, such Interest Payment Date shall be the next succeeding Business Day, unless the next succeeding Business Day is the next succeeding calendar month, in which case such Interest Payment Date shall be the immediately preceding Business Day. Interest on the Notes shall be computed on the basis of a 360-day year and the actual number of days in the Observation Period. On each Interest Payment Determination Date relating to the applicable Interest Payment Date, the Calculation Agent will calculate the amount of accrued interest payable on the Notes for each Interest Period by multiplying (i) the outstanding principal amount of the Notes by (ii) the product of (a) the interest rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in such Observation Period divided by 360. Interest on the Notes shall accrue from July 26, 2023. The interest rate on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. Additionally, the interest rate on the Notes will in no event be lower than zero. The notes shall not be subject to redemption prior to maturity.

(c) Effect of Benchmark Transition Event.

(1) Notwithstanding anything to the contrary in the Base Indenture, this Twelfth Supplemental Indenture and the Notes, if the Issuer or its designee determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining Compounded SOFR, then the benchmark replacement provisions set forth in this Section 1.4(c) will thereafter apply to all determinations of the rate of interest payable on the Notes. For the avoidance of doubt, in accordance with this Section 1.4(c), after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate for each Interest Period on the Notes will be an annual rate equal to the sum of the Benchmark Replacement and the applicable margin.

(2) If the Issuer or its designee determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes in respect of such determination on such date and all determinations on all subsequent dates.

13

(3) In connection with the implementation of a Benchmark Replacement, the Issuer or its designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

(4) Any determination, decision or election that may be made by the Issuer or its designee pursuant to this Section 1.4(c), including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection: (i) will be conclusive and binding absent manifest error; (ii) if made by the Issuer, will be made in its sole discretion; (iii) if made by the Issuer’s designee, will be made after consultation with the Issuer, and such designee will not make any such determination, decision or election to which the Issuer objects; and (iv) notwithstanding anything to the contrary in the Base Indenture, this Twelfth Supplemental Indenture or the Notes, shall become effective without consent from the holders of the Notes or any other party.

Any determination, decision or election pursuant to the benchmark replacement provisions shall be made by the Issuer or its designee (which may be the Issuer’s affiliate) on the basis as described above, and in no event shall the Calculation Agent be responsible for making any such determination, decision or election. The Issuer shall notify the Trustee and the Calculation Agent in writing of the party that has been appointed by the Issuer as its designee.

(5) The interest rate and amount of interest to be paid on the Notes for each Interest Period will be determined by the Calculation Agent. The Issuer may change the Calculation Agent at any time without notice and the Calculation Agent may resign as Calculation Agent at any time with prior written notice to the Issuer. The Calculation Agent will, upon the request of any Holder of the Notes, provide the interest rate then in effect with respect to the Notes. All calculations made by the Calculation Agent shall in the absence of manifest error be conclusive for all purposes and binding on the Issuer and the Holders of the Notes. So long as Compounded SOFR is required to be determined with respect to the Notes, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail to duly establish Compounded SOFR for any Interest Period, or that the Issuer proposes to remove such Calculation Agent, the Issuer shall appoint another calculation agent.

(6) None of the Trustee, the Paying Agent and the Calculation Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR Index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, or (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, interest determination dates or any other

14

relevant methodology applicable to such substitute or successor benchmark. In connection with the foregoing, each of the Trustee, the Paying Agent and the Calculation Agent shall be entitled to conclusively rely on any determinations made by the Issuer or its designee without independent investigation, and none will have any liability for actions taken at the Issuer’s direction in connection therewith.

(7) None of the Trustee, the Paying Agent and the Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth herein as a result of the unavailability of SOFR, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of the Notes and reasonably required for the performance of such duties. None of the Trustee, the Paying Agent or the Calculation Agent shall be responsible or liable for the Issuer’s actions or omissions or for those of its designee, or for any failure or delay in the performance by the Issuer or its designee, nor shall any of the Trustee, the Paying Agent or the Calculation Agent be under any obligation to oversee or monitor the Issuer’s performance or that of its designee.

(d) Sinking Fund. There shall be no sinking fund provided for the Notes.

(e) Additional Issues. The Issuer may, from time to time, without the consent of or notice to the Holders of the Notes, create and issue further notes having the same terms and conditions as the Notes in all respects, except for the issue date and, to the extent applicable, the issue price, the payment of interest accruing prior to the issue date and the first Interest Payment Date. Additional notes issued in this manner shall be consolidated with, and shall form a single series with, the previously outstanding Notes; provided, however, that the issuance of such additional notes will not be so consolidated for United States federal income tax purposes unless such issuance constitutes a “qualified reopening” within the meaning of the Internal Revenue Code of 1986, as amended, and the Treasury regulations promulgated thereunder.

Section 1.5 Book-Entry Provisions. This Section 1.5 shall apply only to the Global Notes deposited with or on behalf of the Depository.

(a) The Issuer shall execute and the Trustee shall, in accordance with this Section 1.5 and Section 303 of the Base Indenture, authenticate and deliver the Global Notes that shall be registered in the name of the Depository or its nominee and shall be held by the Trustee as custodian for the Depository.

(b) Participants of the Depository shall have no rights either under the Indenture or with respect to the Global Notes. The Depository or its nominee, as applicable, shall be treated by the Issuer, any future Guarantor, the Trustee and any agent of the Issuer, any future Guarantor or the Trustee as the absolute owner and Holder of each such Global Note for all purposes under the Indenture. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, any future Guarantor or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or its nominee, as applicable, or impair, as between the Depository and its participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in the Global Notes.

ARTICLE TWO

ADDITIONAL COVENANTS FOR BENEFIT OF HOLDERS OF NOTES

In addition to the covenants set forth in the Base Indenture, the Issuer hereby further covenants as follows, the following covenants being for the sole benefit of the Holders of the Notes:

Section 2.1 Limitations on Incurrence of Debt.

(a) Aggregate Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and any other Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Debt and the application of the proceeds from such Debt and such other Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Debt would exceed 65% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

(b) Secured Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Secured Debt if, immediately after giving effect to the incurrence of such Secured Debt and any other Secured Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Secured Debt and the application of the proceeds from such Secured Debt and such other Secured Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Secured Debt would exceed 50% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Secured Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

16

(c) Debt Service Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the ratio of Adjusted EBITDA to Interest Expense for the four (4) consecutive fiscal quarters ended on the most recent Reporting Date prior to the incurrence of such Debt would be less than 1.50 to 1.00, and calculated on the following assumptions (without duplication): (1) such Debt and any other Debt incurred since such Reporting Date and outstanding on the date of determination had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such four-quarter period; (2) the repayment or retirement of any other Debt since such Reporting Date had occurred on the first day of such four-quarter period; and (3) in the case of any acquisition or disposition by the Issuer or any of its Subsidiaries of any asset or group of assets since such Reporting Date, whether by merger, stock purchase or sale or asset purchase or sale or otherwise, such acquisition or disposition had occurred as of the first day of such four-quarter period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation. If any Debt incurred during the period from such Reporting Date to the date of determination bears interest at a floating rate, then, for purposes of calculating the Interest Expense, the interest rate on such Debt will be computed on a pro forma basis as if the average daily rate during such interim period had been the applicable rate for the entire relevant four-quarter period. For purposes of the foregoing, Debt will be deemed to be incurred by a Person whenever such Person creates, assumes, guarantees or otherwise becomes liable in respect thereof.

(d) Maintenance of Total Unencumbered Assets. As of each Reporting Date, the Issuer’s Unencumbered Assets will not be less than 125% of the Issuer’s Unsecured Debt.

Section 2.2 Possible Future Parent Guarantee. The Notes will not be guaranteed by any of the Issuer’s Subsidiaries or initially by any other entity.

However, if in the future, (i) the Issuer undergoes a corporate reorganization that results in the Issuer becoming a subsidiary of a real estate investment trust (the “Parent”) and (ii) the Parent guarantees amounts outstanding under the Credit Facility, then the Parent shall provide, within 10 Business Days, through the execution and delivery of a supplemental indenture in accordance with the terms of the Indenture, a guarantee of the Notes, guaranteeing the payment of principal of and premium, if any, and interest on the Notes when due on an unsecured and unsubordinated basis (the “Possible Future Parent Guarantee”), and shall be subject to and bound by all of the terms and provisions of the Indenture applicable to a Guarantor.

If at any time (y) the Parent no longer guarantees the Credit Facility and (z) no Event of Default shall have occurred and be continuing, then the Parent’s obligations to be a Guarantor of the Notes under any Possible Future Parent Guarantee shall immediately cease and automatically be terminated (including the effectiveness of any supplemental indenture executed pursuant to the preceding paragraph) from such date and without any other action by any Person and without the execution or delivery of any supplemental indenture or other instrument; provided that the Issuer shall deliver to the Trustee an Officer’s Certificate to the effect that the Parent’s obligation to be a Guarantor under any Possible Future Parent Guarantee shall have ceased and terminated; provided, further, that if, following the cessation and termination of such obligation, the Parent subsequently guarantees the Credit Facility, it shall again be required to guarantee the Notes to the extent provided herein.

17

Section 2.3 Covenant Defeasance and Waiver of Covenant. The covenants set forth in Sections 2.1 and 2.2 shall be subject to covenant defeasance under Section 402(3) of the Base Indenture and subject to waiver under Section 1006 thereof.

Section 2.4 Merger, Consolidation or Sale. The Issuer may consolidate with or into, or sell, assign, convey, transfer or lease all or substantially all of its property and assets to, any other entity, provided that:

ARTICLE THREE

TRUSTEE

Section 3.1 Trustee. The Trustee is appointed as the principal paying agent, transfer agent and registrar for the Notes and for the purposes of Section 1002 of the Base Indenture. The Notes may be presented for payment at the Corporate Trust Office of the Trustee or at any other agency as may be appointed from time to time by the Issuer in the continental United States.

The recitals of fact contained herein shall be taken as the statements solely of the Issuer, and the Trustee assumes no responsibility for the correctness thereof.

18

If the Trustee shall be or become a creditor of the Issuer (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Issuer (or any such other obligor). The Trustee is permitted to engage in other transactions with the Issuer and its Affiliates. If, however, it acquires any conflicting interest under the Trust Indenture Act relating to any of its duties with respect to the Notes, it must eliminate that conflict or resign, subject to its right under the Trust Indenture Act to seek a stay of its duty to resign.

ARTICLE FOUR

FLOATING RATE SENIOR NOTE DUE 2025

This Note is one of a duly authorized issue of Notes of the Issuer, designated as its Floating Rate Senior Notes due 2025 (herein called the “Notes”), issued under and pursuant to an Indenture dated as of September 18, 2017 (herein called the “Base Indenture”), between the Issuer and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee (herein called the “Trustee”), as supplemented by the Twelfth Supplemental Indenture dated as of July 26, 2023 (herein called the “Twelfth Supplemental Indenture,” and together with the Base Indenture, the “Indenture”), between the Issuer and the Trustee, to which Indenture and any indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the Holders of the Notes. Defined terms used but not otherwise defined in this Note shall have the respective meanings ascribed thereto in the Indenture.

If an Event of Default (other than an Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all Notes may be declared to be due and payable by either the Trustee or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding, and, upon said declaration the same shall be immediately due and payable. If an Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture occurs, the principal of and premium, if any, and interest accrued and unpaid on all the Notes shall be immediately and automatically due and payable without necessity of further action.

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture with respect to the Notes or modifying in any manner the rights of the Holders of the Notes, subject to exceptions set forth in Section 902 of the Base Indenture. Subject to the provisions of the Indenture, the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may, on behalf of the Holders of all of the Notes, waive any past default or Event of Default with respect to the Notes, subject to exceptions set forth in the Indenture.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Issuer and the Holder of the Notes, the obligation of the Issuer, which is absolute and unconditional, to pay the principal of, premium, if any, on and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture prescribed.

Interest on the Notes shall be computed on the basis of a 360-day year and the actual number of days in the Observation Period.

A-5

The Notes are issuable in fully registered form, without coupons, in minimum denominations of $2,000 principal amount and any multiple of $1,000 in excess thereof. At the office or agency of the Issuer referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, Notes may be transferred or may be exchanged for a like aggregate principal amount of Notes of any other authorized denominations.

The Notes are not subject to redemption prior to maturity, including through the operation of any sinking fund.

Except to the extent expressly provided in Article Sixteen of the Base Indenture, no recourse for the payment of the principal of or any premium or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Issuer or any future Guarantor in the Indenture or any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any past, present or future general partner, limited partner, member, employee, incorporator, controlling person, stockholder, officer, director or agent, as such, of the Issuer, any future Guarantor or of any of the Issuer’s or any future Guarantor’s predecessors or successors, either directly or through the Issuer or any future Guarantor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Notes by the Holders thereof and as part of the consideration for the issue of the Notes.

The interest rate on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. Additionally, the interest rate on the Notes will in no event be lower than zero.

On each Interest Payment Determination Date relating to the applicable Interest Payment Date, Computershare Trust Company, N.A. (the “Calculation Agent”) will calculate the amount of accrued interest payable on the Notes for each Interest Period by multiplying (i) the outstanding principal amount of the Notes by (ii) the product of (a) the interest rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in such Observation Period divided by 360.

“Interest Period” means (i) the period commencing on any Interest Payment Date (or, with respect to the initial Interest Period only, commencing on July 26, 2023) to, but excluding, the next succeeding Interest Payment Date; or (ii) in the case of the last such Interest Period, from, and including, the Interest Payment Date immediately preceding the Maturity Date to but excluding such Maturity Date.

A-6

“Compounded SOFR” will be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point):

where:

“SOFR Index_Start” = For periods other than the initial Interest Period, the SOFR Index value on the preceding Interest Payment Determination Date, and, for the initial Interest Period, the SOFR Index value on July 24, 2023;

“SOFR Index_End” = The SOFR Index value on the Interest Payment Determination Date relating to the applicable Interest Payment Date (or in the final Interest Period, relating to the Maturity Date); and

“d_c” is the number of calendar days in the relevant Observation Period.

For purposes of determining Compounded SOFR,

“Interest Payment Determination Date” means the date two U.S. Government Securities Business Days before each Interest Payment Date (or in the final Interest Period, before the Maturity Date).

“Observation Period” means, in respect of each Interest Period, the period from, and including, the date two U.S. Government Securities Business Days preceding the first date in such Interest Period to, but excluding, the date two U.S. Government Securities Business Days preceding the Interest Payment Date for such Interest Period (or in the final Interest Period, preceding the Maturity Date).

“SOFR Index” means, with respect to any U.S. Government Securities Business Day:

(1) the SOFR Index value as published by the SOFR Administrator as such index appears on the SOFR Administrator’s Website at 3:00 p.m. (New York time) on such U.S. Government Securities Business Day (the “SOFR Index Determination Time”); provided that:

A-7

(2) if a SOFR Index value does not so appear as specified in (1) above at the SOFR Index Determination Time, then: (i) if a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the last paragraph of the definition of “Compounded SOFR” in the Twelfth Supplemental Indenture; or (ii) if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the provisions described below.

“SOFR” means the daily secured overnight financing rate as provided by the SOFR Administrator on the SOFR Administrator’s Website.

“SOFR Administrator” means the Federal Reserve Bank of New York (or any successor administrator of SOFR).

“SOFR Administrator’s Website” means the website of the Federal Reserve Bank of New York, which as of the date of the Twelfth Supplemental Indenture is at http://www.newyorkfed.org, or any successor source.

“U.S. Government Securities Business Day” means any day except for a Saturday, a Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

Notwithstanding anything to the contrary in the documentation relating to the Notes, if the Issuer or its designee determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining Compounded SOFR, then the benchmark replacement provisions set forth below will thereafter apply to all determinations of the rate of interest payable on the Notes.

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate for each Interest Period on the Notes will be an annual rate equal to the sum of the Benchmark Replacement and the applicable margin.

If a SOFR Index_Start or SOFR Index_End is not published on the associated Interest Payment Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded SOFR” means, for the applicable Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for “SOFR Averages”, and definitions required for such formula, published on the SOFR Administrator’s Website, initially located at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information. For the purposes of this paragraph, references in the “SOFR Averages” compounding formula and related definitions to “calculation period” shall be replaced with “Observation Period” and the words “that is, 30-, 90-, or 180- calendar days” shall be removed. If SOFR does not so appear for any day “i” in the Observation Period, SOFR_i for such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator’s Website.

A-8

If the Issuer or its designee determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes in respect of such determination on such date and all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, the Issuer or its designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by the Issuer or its designee pursuant to the benchmark replacement provisions described herein, including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection: (i) will be conclusive and binding absent manifest error; (ii) if made by the Issuer, will be made in its sole discretion; (iii) if made by the Issuer’s designee, will be made after consultation with the Issuer, and such designee will not make any such determination, decision or election to which the Issuer objects; and (iv) notwithstanding anything to the contrary in the Base Indenture, the Twelfth Supplemental Indenture and herein, shall become effective without consent from the holders of the Notes or any other party.

Any determination, decision or election pursuant to the benchmark replacement provisions shall be made by the Issuer or its designee (which may be the Issuer’s affiliate) on the basis as described above, and in no event shall the Calculation Agent be responsible for making any such determination, decision or election.

“Benchmark” means, initially, Compounded SOFR, as such term is defined above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

A-9

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Issuer or its designee as of the Benchmark Replacement Date:

(2) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

(3) the sum of: (a) the alternate rate of interest that has been selected by the Issuer or its designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Issuer or its designee as of the Benchmark Replacement Date:

(2) in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

(1) a public statement or publication of information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component);

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Index Determination Time, as such time is defined above, and (2) if the Benchmark is not Compounded SOFR, the time determined by the Issuer or its designee in accordance with the Benchmark Replacement Conforming Changes.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

The interest rate and amount of interest to be paid on the Notes for each Interest Period will be determined by the Calculation Agent. Computershare Trust Company, N.A. is currently serving as the Calculation Agent; however, the Issuer may change the Calculation Agent at any time without notice and Computershare Trust Company, N.A. may resign as Calculation Agent at any time with prior written notice to the Issuer. The Calculation Agent will, upon the request of any Holder of the Notes, provide the interest rate then in effect with respect to the Notes. All calculations made by the Calculation Agent shall in the absence of manifest error be conclusive for all purposes and binding on the Issuer and the Holders of the Notes. So long as Compounded SOFR is required to be determined with respect to the Notes, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail to duly establish Compounded SOFR for any Interest Period, or that the Issuer proposes to remove such Calculation Agent, the Issuer shall appoint another calculation agent.

None of the Trustee, the Paying Agent and the Calculation Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR Index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, or (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, interest determination dates or any other relevant methodology applicable to such substitute or successor benchmark. In connection with the foregoing, each of the Trustee, the Paying Agent and the Calculation Agent shall be entitled to conclusively rely on any determinations made by the Issuer or its designee without independent investigation, and none will have any liability for actions taken at the Issuer’s direction in connection therewith.

None of the Trustee, the Paying Agent and the Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth herein a result of the unavailability of SOFR, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of this Note and reasonably required for the performance of such duties. None of the Trustee, the Paying Agent or the Calculation Agent shall be responsible or liable for the Issuer’s actions or omissions or for those of its designee, or for any failure or delay in the performance by the Issuer or its designee, nor shall any of the trustee, the paying agent or the Calculation Agent be under any obligation to oversee or monitor the Issuer’s performance or that of its designee.

For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

7

If on the third Business Day preceding the date the notice of redemption is given H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Unencumbered Assets” means, as of any date, Total Assets as of such date less Encumbered Asset Value as of such date.

So long as the Depository, or its nominee, is the registered owner of the Global Note, the Depository or its nominee, as the case may be, will be considered the sole Holder of the Notes represented by the Global Note for all purposes under the Indenture.

(3) Notwithstanding the foregoing, if the Redemption Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Issuer will pay the full amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). The Issuer shall not redeem the Notes pursuant to Section 1.4(d)(1) or (2) on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed).

(e) Payment of Notes Called for Redemption by the Issuer.

(1) If notice of redemption has been given at least 10 days but not more than 60 days prior to the Redemption Date to each Holder of Notes to be redeemed as otherwise provided in Article Eleven of the Base Indenture (as amended by this Thirteenth Supplemental Indenture), the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Issuer shall default in the payment of such Notes at the Redemption Price, so long as the Paying Agent holds funds irrevocably deposited with it sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, then (a) such Notes will cease to be Outstanding on and after the date of the deposit, (b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date, and (c) the Holders of the Notes being redeemed shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On surrender of such Notes at the place of payment specified in such notice, the said Notes or the specified portions thereof shall be paid and redeemed by the Issuer at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date.

(2) The Notes will not be convertible or exchangeable for any other security or property.

(f) Additional Issues. The Issuer may, from time to time, without the consent of or notice to the Holders of the Notes, create and issue further notes having the same terms and conditions as the Notes in all respects, except for the issue date and, to the extent applicable, the issue price, the payment of interest accruing prior to the issue date and the first Interest Payment Date. Additional notes issued in this manner shall be consolidated with, and shall form a single series with, the previously outstanding Notes; provided, however, that the issuance of such additional notes will not be so consolidated for United States federal income tax purposes unless such issuance constitutes a “qualified reopening” within the meaning of the Internal Revenue Code of 1986, as amended, and the Treasury regulations promulgated thereunder.

Section 1.5 Book-Entry Provisions. This Section 1.5 shall apply only to the Global Notes deposited with or on behalf of the Depository.

(a) The Issuer shall execute and the Trustee shall, in accordance with this Section 1.5 and Section 303 of the Base Indenture, authenticate and deliver the Global Notes that shall be registered in the name of the Depository or its nominee and shall be held by the Trustee as custodian for the Depository.

10

(b) Participants of the Depository shall have no rights either under the Indenture or with respect to the Global Notes. The Depository or its nominee, as applicable, shall be treated by the Issuer, any future Guarantor, the Trustee and any agent of the Issuer, any future Guarantor, or the Trustee as the absolute owner and Holder of each such Global Note for all purposes under the Indenture. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, any future Guarantor, or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or its nominee, as applicable, or impair, as between the Depository and its participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in the Global Notes.

ARTICLE TWO

ADDITIONAL COVENANTS FOR BENEFIT OF HOLDERS OF NOTES

In addition to the covenants set forth in the Base Indenture, the Issuer hereby further covenants as follows, the following covenants being for the sole benefit of the Holders of the Notes:

Section 2.1 Limitations on Incurrence of Debt.

(a) Aggregate Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and any other Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Debt and the application of the proceeds from such Debt and such other Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Debt would exceed 65% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

(b) Secured Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Secured Debt if, immediately after giving effect to the incurrence of such Secured Debt and any other Secured Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Secured Debt and the application of the proceeds from such Secured Debt and such other Secured Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Secured Debt would exceed 50% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase

11

price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Secured Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

(c) Debt Service Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the ratio of Adjusted EBITDA to Interest Expense for the four (4) consecutive fiscal quarters ended on the most recent Reporting Date prior to the incurrence of such Debt would be less than 1.50 to 1.00, and calculated on the following assumptions (without duplication): (1) such Debt and any other Debt incurred since such Reporting Date and outstanding on the date of determination had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such four-quarter period; (2) the repayment or retirement of any other Debt since such Reporting Date had occurred on the first day of such four-quarter period; and (3) in the case of any acquisition or disposition by the Issuer or any of its Subsidiaries of any asset or group of assets since such Reporting Date, whether by merger, stock purchase or sale or asset purchase or sale or otherwise, such acquisition or disposition had occurred as of the first day of such four-quarter period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation. If any Debt incurred during the period from such Reporting Date to the date of determination bears interest at a floating rate, then, for purposes of calculating the Interest Expense, the interest rate on such Debt will be computed on a pro forma basis as if the average daily rate during such interim period had been the applicable rate for the entire relevant four-quarter period. For purposes of the foregoing, Debt will be deemed to be incurred by a Person whenever such Person creates, assumes, guarantees or otherwise becomes liable in respect thereof.

(d) Maintenance of Total Unencumbered Assets. As of each Reporting Date, the Issuer’s Unencumbered Assets will not be less than 125% of the Issuer’s Unsecured Debt.

Section 2.2 Possible Future Parent Guarantee. The Notes will not be guaranteed by any of the Issuer’s Subsidiaries or initially by any other entity.

However, if in the future, (i) the Issuer undergoes a corporate reorganization that results in the Issuer becoming a subsidiary of a real estate investment trust (the “Parent”) and (ii) the Parent guarantees amounts outstanding under the Credit Facility, then the Parent shall provide, within 10 Business Days, through the execution and delivery of a supplemental indenture in accordance with the terms of the Indenture, a guarantee of the Notes, guaranteeing the payment of principal of and premium, if any, and interest on the Notes when due on an unsecured and unsubordinated basis (the “Possible Future Parent Guarantee”), and shall be subject to and bound by all of the terms and provisions of the Indenture applicable to a Guarantor.

12

If at any time (y) the Parent no longer guarantees the Credit Facility and (z) no Event of Default shall have occurred and be continuing, then the Parent’s obligations to be a Guarantor of the Notes under any Possible Future Parent Guarantee shall immediately cease and automatically be terminated (including the effectiveness of any supplemental indenture executed pursuant to the preceding paragraph) from such date and without any other action by any Person and without the execution or delivery of any supplemental indenture or other instrument; provided that the Issuer shall deliver to the Trustee an Officer’s Certificate to the effect that the Parent’s obligation to be a Guarantor under any Possible Future Parent Guarantee shall have ceased and terminated; provided, further, that if, following the cessation and termination of such obligation, the Parent subsequently guarantees the Credit Facility, it shall again be required to guarantee the Notes to the extent provided herein.

Section 2.3 Covenant Defeasance and Waiver of Covenant. The covenants set forth in Sections 2.1 and 2.2 shall be subject to covenant defeasance under Section 402(3) of the Base Indenture and subject to waiver under Section 1006 thereof.

Section 2.4 Merger, Consolidation or Sale. The Issuer may consolidate with or into, or sell, assign, convey, transfer or lease all or substantially all of its property and assets to, any other entity, provided that:

The Trustee is permitted to engage in other transactions with the Issuer and its Affiliates. If, however, it acquires any conflicting interest under the Trust Indenture Act relating to any of its duties with respect to the Notes, it must eliminate that conflict or resign, subject to its right under the Trust Indenture Act to seek a stay of its duty to resign.

Section 3.3 Calculation with Respect to the Notes. The Issuer shall be responsible for making all calculations required under this Thirteenth Supplemental Indenture or with respect to the Notes. The Issuer will make such calculations in good faith and, absent manifest error, the Issuer’s calculations will be final and binding on the Trustee and the Holders of the Notes. The Issuer shall provide a schedule of its calculations to the Trustee promptly after it makes such calculations, and the Trustee shall be entitled to rely upon the accuracy of the Issuer’s calculations without independent verification. The Trustee shall forward the Issuer’s calculations to any Holder of the Notes upon request of the Issuer.

5.125% SENIOR NOTE DUE 2029

This Note is one of a duly authorized issue of Notes of the Issuer, designated as its 5.125% Senior Notes due 2029 (herein called the “Notes”), issued under and pursuant to an Indenture dated as of September 18, 2017 (herein called the “Base Indenture”), between the Issuer and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee (herein called the “Trustee”), as supplemented by the Thirteenth Supplemental Indenture dated as of July 26, 2023 (herein called the “Thirteenth Supplemental Indenture,” and together with the Base Indenture, the “Indenture”), between the Issuer and the Trustee, to which Indenture and any indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the Holders of the Notes. Defined terms used but not otherwise defined in this Note shall have the respective meanings ascribed thereto in the Indenture.

The Issuer shall have the right to redeem the Notes under certain circumstances as set forth in Section 1.4(d) of the Thirteenth Supplemental Indenture and Article Eleven of Base Indenture.

Prior to the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(x) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date, and

(y) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to the Redemption Date.

The Issuer shall not redeem the Notes pursuant to Section 1.4(d)(1) or (2) of the Thirteenth Supplemental Indenture on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed).

A-5

If an Event of Default (other than an Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all Notes may be declared to be due and payable by either the Trustee or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding, and, upon said declaration the same shall be immediately due and payable. If an Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture occurs, the principal of and premium, if any, and interest accrued and unpaid on all the Notes shall be immediately and automatically due and payable without necessity of further action.

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture with respect to the Notes or modifying in any manner the rights of the Holders of the Notes, subject to exceptions set forth in Section 902 of the Base Indenture. Subject to the provisions of the Indenture, the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may, on behalf of the Holders of all of the Notes, waive any past default or Event of Default with respect to the Notes, subject to exceptions set forth in the Indenture.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Issuer and the Holder of the Notes, the obligation of the Issuer, which is absolute and unconditional, to pay the principal of, premium, if any, on and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture prescribed.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

The Notes are issuable in fully registered form, without coupons, in minimum denominations of $2,000 principal amount and any multiple of $1,000 in excess thereof. At the office or agency of the Issuer referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, Notes may be transferred or may be exchanged for a like aggregate principal amount of Notes of any other authorized denominations.

The Notes are not subject to redemption through the operation of any sinking fund.

Except to the extent expressly provided in Article Sixteen of the Base Indenture, no recourse for the payment of the principal of or any premium or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Issuer in the Indenture or any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any past,

In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the date the notice of redemption is given H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United

7

States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Unencumbered Assets” means, as of any date, Total Assets as of such date less Encumbered Asset Value as of such date.

Section 1.2 Creation of the Notes. In accordance with Section 301 of the Base Indenture, the Issuer hereby creates the Notes as a separate series of its senior debt securities, entitled “5.100% Senior Notes due 2033”, issued pursuant to the Indenture. The Notes shall initially be limited to an aggregate principal amount equal to $700,000,000, subject to the exceptions set forth in Section 301(2) of the Base Indenture and Section 1.4(f) hereof.

Section 1.3 Form of the Notes. The Notes will be issued in the form of one or more permanent fully registered global securities (the “Global Note”) that will be deposited with, or on behalf of the Depository, and registered in the name of the Depository or its nominee, as the case may be, subject to Section 305 of the Base Indenture. So long as the Depository, or its nominee, is the registered owner of the Global Note, the Depository or its nominee, as the case may be, will be considered the sole Holder of the Notes represented by the Global Note for all purposes under the Indenture.

Section 1.4 Terms and Provisions of the Notes. The Notes shall be governed by all of the terms and provisions of the Base Indenture, as supplemented by this Fourteenth Supplemental Indenture, and in particular, the following provisions shall be terms of the Notes:

(a) Registration and Form. The Notes shall be issuable in registered form without coupons in minimum denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. Each Note shall be dated the date of its authentication and the Notes shall be substantially in the form of Exhibit A attached hereto.

8

(b) Payment of Principal and Interest. All payments of principal, premiums, if any, and interest in respect of the Global Notes will be made by the Issuer in immediately available funds to the Depository or its nominee, as the case may be, as the Holder of each of the Global Notes. The Notes shall mature, and the unpaid principal thereon, shall be payable, on August 1, 2033, subject to the provisions of the Base Indenture. The rate per annum at which interest shall be payable on the Notes shall be 5.100%. Interest on the Notes will be payable semi-annually in arrears on each February 1 and August 1, commencing February 1, 2024 (each, an “Interest Payment Date”) and on the Stated Maturity as specified in this Section 1.4(b), to the Persons in whose names the Notes are registered in the Security Register applicable to the Notes at the close of business on the fifteenth calendar day (whether or not a Business Day) immediately preceding each Interest Payment Date. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. Interest on the Notes shall accrue from July 26, 2023.

(c) Sinking Fund. There shall be no sinking fund provided for the Notes.

(d) Redemption at the Option of the Issuer.

(1) Prior to the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(x) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points less (b) interest accrued to the Redemption Date, and

(y) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

(2) On or after the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to the Redemption Date.

(3) Notwithstanding the foregoing, if the Redemption Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Issuer will pay the full amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). The Issuer shall not redeem the Notes pursuant to Section 1.4(d)(1) or (2) on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed).

9

(e) Payment of Notes Called for Redemption by the Issuer.

(1) If notice of redemption has been given at least 10 days but not more than 60 days prior to the Redemption Date to each Holder of Notes to be redeemed as otherwise provided in Article Eleven of the Base Indenture (as amended by this Fourteenth Supplemental Indenture), the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Issuer shall default in the payment of such Notes at the Redemption Price, so long as the Paying Agent holds funds irrevocably deposited with it sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, then (a) such Notes will cease to be Outstanding on and after the date of the deposit, (b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date, and (c) the Holders of the Notes being redeemed shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On surrender of such Notes at the place of payment specified in such notice, the said Notes or the specified portions thereof shall be paid and redeemed by the Issuer at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date.

(2) The Notes will not be convertible or exchangeable for any other security or property.

(f) Additional Issues. The Issuer may, from time to time, without the consent of or notice to the Holders of the Notes, create and issue further notes having the same terms and conditions as the Notes in all respects, except for the issue date and, to the extent applicable, the issue price, the payment of interest accruing prior to the issue date and the first Interest Payment Date. Additional notes issued in this manner shall be consolidated with, and shall form a single series with, the previously outstanding Notes; provided, however, that the issuance of such additional notes will not be so consolidated for United States federal income tax purposes unless such issuance constitutes a “qualified reopening” within the meaning of the Internal Revenue Code of 1986, as amended, and the Treasury regulations promulgated thereunder.

Section 1.5 Book-Entry Provisions. This Section 1.5 shall apply only to the Global Notes deposited with or on behalf of the Depository.

(a) The Issuer shall execute and the Trustee shall, in accordance with this Section 1.5 and Section 303 of the Base Indenture, authenticate and deliver the Global Notes that shall be registered in the name of the Depository or its nominee and shall be held by the Trustee as custodian for the Depository.

(b) Participants of the Depository shall have no rights either under the Indenture or with respect to the Global Notes. The Depository or its nominee, as applicable, shall be treated by the Issuer, any future Guarantor, the Trustee and any agent of the Issuer, any future Guarantor, or the Trustee as the absolute owner and Holder of each such Global Note for all

10

purposes under the Indenture. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, any future Guarantor, or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or its nominee, as applicable, or impair, as between the Depository and its participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in the Global Notes.

ARTICLE TWO

ADDITIONAL COVENANTS FOR BENEFIT OF HOLDERS OF NOTES

In addition to the covenants set forth in the Base Indenture, the Issuer hereby further covenants as follows, the following covenants being for the sole benefit of the Holders of the Notes:

Section 2.1 Limitations on Incurrence of Debt.

(a) Aggregate Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and any other Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Debt and the application of the proceeds from such Debt and such other Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Debt would exceed 65% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

(b) Secured Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Secured Debt if, immediately after giving effect to the incurrence of such Secured Debt and any other Secured Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Secured Debt and the application of the proceeds from such Secured Debt and such other Secured Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Secured Debt would exceed 50% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Secured Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

11

(c) Debt Service Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the ratio of Adjusted EBITDA to Interest Expense for the four (4) consecutive fiscal quarters ended on the most recent Reporting Date prior to the incurrence of such Debt would be less than 1.50 to 1.00, and calculated on the following assumptions (without duplication): (1) such Debt and any other Debt incurred since such Reporting Date and outstanding on the date of determination had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such four-quarter period; (2) the repayment or retirement of any other Debt since such Reporting Date had occurred on the first day of such four-quarter period; and (3) in the case of any acquisition or disposition by the Issuer or any of its Subsidiaries of any asset or group of assets since such Reporting Date, whether by merger, stock purchase or sale or asset purchase or sale or otherwise, such acquisition or disposition had occurred as of the first day of such four-quarter period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation. If any Debt incurred during the period from such Reporting Date to the date of determination bears interest at a floating rate, then, for purposes of calculating the Interest Expense, the interest rate on such Debt will be computed on a pro forma basis as if the average daily rate during such interim period had been the applicable rate for the entire relevant four-quarter period. For purposes of the foregoing, Debt will be deemed to be incurred by a Person whenever such Person creates, assumes, guarantees or otherwise becomes liable in respect thereof.

(d) Maintenance of Total Unencumbered Assets. As of each Reporting Date, the Issuer’s Unencumbered Assets will not be less than 125% of the Issuer’s Unsecured Debt.

Section 2.2 Possible Future Parent Guarantee. The Notes will not be guaranteed by any of the Issuer’s Subsidiaries or initially by any other entity.

However, if in the future, (i) the Issuer undergoes a corporate reorganization that results in the Issuer becoming a subsidiary of a real estate investment trust (the “Parent”) and (ii) the Parent guarantees amounts outstanding under the Credit Facility, then the Parent shall provide, within 10 Business Days, through the execution and delivery of a supplemental indenture in accordance with the terms of the Indenture, a guarantee of the Notes, guaranteeing the payment of principal of and premium, if any, and interest on the Notes when due on an unsecured and unsubordinated basis (the “Possible Future Parent Guarantee”), and shall be subject to and bound by all of the terms and provisions of the Indenture applicable to a Guarantor.

If at any time (y) the Parent no longer guarantees the Credit Facility and (z) no Event of Default shall have occurred and be continuing, then the Parent’s obligations to be a Guarantor of the Notes under any Possible Future Parent Guarantee shall immediately cease and automatically be terminated (including the effectiveness of any supplemental indenture executed pursuant to the preceding paragraph) from such date and without any other action by any Person and without the execution or delivery of any supplemental indenture or other instrument; provided that the Issuer shall deliver to the Trustee an Officer’s Certificate to the effect that the Parent’s obligation to be a Guarantor under any Possible Future Parent Guarantee shall have ceased and terminated; provided, further, that if, following the cessation and termination of such obligation, the Parent subsequently guarantees the Credit Facility, it shall again be required to guarantee the Notes to the extent provided herein.

12

Section 2.3 Covenant Defeasance and Waiver of Covenant. The covenants set forth in Sections 2.1 and 2.2 shall be subject to covenant defeasance under Section 402(3) of the Base Indenture and subject to waiver under Section 1006 thereof.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs.

In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the date the notice of redemption is given H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United

7

States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Unencumbered Assets” means, as of any date, Total Assets as of such date less Encumbered Asset Value as of such date.

“Unsecured Debt” means Debt that is not secured by any mortgage, lien, pledge, encumbrance or security interest of any kind upon any of the Issuer’s Property or other assets or the Property or other assets of any Subsidiary.

Section 1.2 Creation of the Notes.

The Notes shall initially be limited to an aggregate principal amount equal to $600,000,000, subject to the exceptions set forth in Section 301(2) of the Base Indenture and Section 1.4(f) hereof.

So long as the Depository, or its nominee, is the registered owner of the Global Note, the Depository or its nominee, as the case may be, will be considered the sole Holder of the Notes represented by the Global Note for all purposes under the Indenture.

(a) Registration and Form. The Notes shall be issuable in registered form without coupons in minimum denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. Each Note shall be dated the date of its authentication and the Notes shall be substantially in the form of Exhibit A attached hereto.

8

(b) Payment of Principal and Interest. All payments of principal, premiums, if any, and interest in respect of the Global Notes will be made by the Issuer in immediately available funds to the Depository or its nominee, as the case may be, as the Holder of each of the Global Notes. The Notes shall mature, and the unpaid principal thereon, shall be payable, on August 1, 2053, subject to the provisions of the Base Indenture. The rate per annum at which interest shall be payable on the Notes shall be 5.350%. Interest on the Notes will be payable semi-annually in arrears on each February 1 and August 1, commencing February 1, 2024 (each, an “Interest Payment Date”) and on the Stated Maturity as specified in this Section 1.4(b), to the Persons in whose names the Notes are registered in the Security Register applicable to the Notes at the close of business on the fifteenth calendar day (whether or not a Business Day) immediately preceding each Interest Payment Date. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. Interest on the Notes shall accrue from July 26, 2023.

(c) Sinking Fund. There shall be no sinking fund provided for the Notes.

(d) Redemption at the Option of the Issuer.

(1) Prior to the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(x) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to the Redemption Date, and

(y) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

(2) On or after the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to the Redemption Date.

(3) Notwithstanding the foregoing, if the Redemption Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Issuer will pay the full amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). The Issuer shall not redeem the Notes pursuant to Section 1.4(d)(1) or (2) on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed).

9

(e) Payment of Notes Called for Redemption by the Issuer.

(1) If notice of redemption has been given at least 10 days but not more than 60 days prior to the Redemption Date to each Holder of Notes to be redeemed as otherwise provided in Article Eleven of the Base Indenture (as amended by this Fifteenth Supplemental Indenture), the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Issuer shall default in the payment of such Notes at the Redemption Price, so long as the Paying Agent holds funds irrevocably deposited with it sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, then (a) such Notes will cease to be Outstanding on and after the date of the deposit, (b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date, and (c) the Holders of the Notes being redeemed shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On surrender of such Notes at the place of payment specified in such notice, the said Notes or the specified portions thereof shall be paid and redeemed by the Issuer at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date.

(2) The Notes will not be convertible or exchangeable for any other security or property.

(f) Additional Issues. The Issuer may, from time to time, without the consent of or notice to the Holders of the Notes, create and issue further notes having the same terms and conditions as the Notes in all respects, except for the issue date and, to the extent applicable, the issue price, the payment of interest accruing prior to the issue date and the first Interest Payment Date. Additional notes issued in this manner shall be consolidated with, and shall form a single series with, the previously outstanding Notes; provided, however, that the issuance of such additional notes will not be so consolidated for United States federal income tax purposes unless such issuance constitutes a “qualified reopening” within the meaning of the Internal Revenue Code of 1986, as amended, and the Treasury regulations promulgated thereunder.

Section 1.5 Book-Entry Provisions. This Section 1.5 shall apply only to the Global Notes deposited with or on behalf of the Depository.

(a) The Issuer shall execute and the Trustee shall, in accordance with this Section 1.5 and Section 303 of the Base Indenture, authenticate and deliver the Global Notes that shall be registered in the name of the Depository or its nominee and shall be held by the Trustee as custodian for the Depository.

10

(b) Participants of the Depository shall have no rights either under the Indenture or with respect to the Global Notes. The Depository or its nominee, as applicable, shall be treated by the Issuer, any future Guarantor, the Trustee and any agent of the Issuer, any future Guarantor, or the Trustee as the absolute owner and Holder of each such Global Note for all purposes under the Indenture. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, any future Guarantor, or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or its nominee, as applicable, or impair, as between the Depository and its participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in the Global Notes.

ARTICLE TWO

ADDITIONAL COVENANTS FOR BENEFIT OF HOLDERS OF NOTES

In addition to the covenants set forth in the Base Indenture, the Issuer hereby further covenants as follows, the following covenants being for the sole benefit of the Holders of the Notes:

Section 2.1 Limitations on Incurrence of Debt.

(a) Aggregate Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and any other Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Debt and the application of the proceeds from such Debt and such other Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Debt would exceed 65% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

(b) Secured Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Secured Debt if, immediately after giving effect to the incurrence of such Secured Debt and any other Secured Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Secured Debt and the application of the proceeds from such Secured Debt and such other Secured Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Secured Debt would exceed 50% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Secured Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

11

(c) Debt Service Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the ratio of Adjusted EBITDA to Interest Expense for the four (4) consecutive fiscal quarters ended on the most recent Reporting Date prior to the incurrence of such Debt would be less than 1.50 to 1.00, and calculated on the following assumptions (without duplication): (1) such Debt and any other Debt incurred since such Reporting Date and outstanding on the date of determination had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such four-quarter period; (2) the repayment or retirement of any other Debt since such Reporting Date had occurred on the first day of such four-quarter period; and (3) in the case of any acquisition or disposition by the Issuer or any of its Subsidiaries of any asset or group of assets since such Reporting Date, whether by merger, stock purchase or sale or asset purchase or sale or otherwise, such acquisition or disposition had occurred as of the first day of such four-quarter period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation. If any Debt incurred during the period from such Reporting Date to the date of determination bears interest at a floating rate, then, for purposes of calculating the Interest Expense, the interest rate on such Debt will be computed on a pro forma basis as if the average daily rate during such interim period had been the applicable rate for the entire relevant four-quarter period. For purposes of the foregoing, Debt will be deemed to be incurred by a Person whenever such Person creates, assumes, guarantees or otherwise becomes liable in respect thereof.

(d) Maintenance of Total Unencumbered Assets. As of each Reporting Date, the Issuer’s Unencumbered Assets will not be less than 125% of the Issuer’s Unsecured Debt.

Section 2.2 Possible Future Parent Guarantee. The Notes will not be guaranteed by any of the Issuer’s Subsidiaries or initially by any other entity.

However, if in the future, (i) the Issuer undergoes a corporate reorganization that results in the Issuer becoming a subsidiary of a real estate investment trust (the “Parent”) and (ii) the Parent guarantees amounts outstanding under the Credit Facility, then the Parent shall provide, within 10 Business Days, through the execution and delivery of a supplemental indenture in accordance with the terms of the Indenture, a guarantee of the Notes, guaranteeing the payment of principal of and premium, if any, and interest on the Notes when due on an unsecured and unsubordinated basis (the “Possible Future Parent Guarantee”), and shall be subject to and bound by all of the terms and provisions of the Indenture applicable to a Guarantor.

If at any time (y) the Parent no longer guarantees the Credit Facility and (z) no Event of Default shall have occurred and be continuing, then the Parent’s obligations to be a Guarantor of the Notes under any Possible Future Parent Guarantee shall immediately cease and automatically be terminated (including the effectiveness of any supplemental indenture executed pursuant to the preceding paragraph) from such date and without any other action by any Person and without the execution or delivery of any supplemental indenture or other instrument; provided that the Issuer shall deliver to the Trustee an Officer’s Certificate to the effect that the Parent’s obligation to be a Guarantor under any Possible Future Parent Guarantee shall have ceased and terminated; provided, further, that if, following the cessation and termination of such obligation, the Parent subsequently guarantees the Credit Facility, it shall again be required to guarantee the Notes to the extent provided herein.

12

Section 2.3 Covenant Defeasance and Waiver of Covenant. The covenants set forth in Sections 2.1 and 2.2 shall be subject to covenant defeasance under Section 402(3) of the Base Indenture and subject to waiver under Section 1006 thereof.

Section 2.4 Merger, Consolidation or Sale. The Issuer may consolidate with or into, or sell, assign, convey, transfer or lease all or substantially all of its property and assets to, any other entity, provided that:

The Trustee is permitted to engage in other transactions with the Issuer and its Affiliates. If, however, it acquires any conflicting interest under the Trust Indenture Act relating to any of its duties with respect to the Notes, it must eliminate that conflict or resign, subject to its right under the Trust Indenture Act to seek a stay of its duty to resign.

Section 3.3 Calculation with Respect to the Notes. The Issuer shall be responsible for making all calculations required under this Fifteenth Supplemental Indenture or with respect to the Notes. The Issuer will make such calculations in good faith and, absent manifest error, the Issuer’s calculations will be final and binding on the Trustee and the Holders of the Notes. The Issuer shall provide a schedule of its calculations to the Trustee promptly after it makes such calculations, and the Trustee shall be entitled to rely upon the accuracy of the Issuer’s calculations without independent verification. The Trustee shall forward the Issuer’s calculations to any Holder of the Notes upon request of the Issuer.

5.350% SENIOR NOTE DUE 2053

This Note is one of a duly authorized issue of Notes of the Issuer, designated as its 5.350% Senior Notes due 2053 (herein called the “Notes”), issued under and pursuant to an Indenture dated as of September 18, 2017 (herein called the “Base Indenture”), between the Issuer and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee (herein called the “Trustee”), as supplemented by the Fifteenth Supplemental Indenture dated as of July 26, 2023 (herein called the “Fifteenth Supplemental Indenture,” and together with the Base Indenture, the “Indenture”), between the Issuer and the Trustee, to which Indenture and any indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the Holders of the Notes. Defined terms used but not otherwise defined in this Note shall have the respective meanings ascribed thereto in the Indenture.

The Issuer shall have the right to redeem the Notes under certain circumstances as set forth in Section 1.4(d) of the Fifteenth Supplemental Indenture and Article Eleven of Base Indenture.

Prior to the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(x) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to the Redemption Date, and

(y) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to the Redemption Date.

The Issuer shall not redeem the Notes pursuant to Section 1.4(d)(1) or (2) of the Fifteenth Supplemental Indenture on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed).

A-5

If an Event of Default (other than an Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all Notes may be declared to be due and payable by either the Trustee or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding, and, upon said declaration the same shall be immediately due and payable. If an Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture occurs, the principal of and premium, if any, and interest accrued and unpaid on all the Notes shall be immediately and automatically due and payable without necessity of further action.

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture with respect to the Notes or modifying in any manner the rights of the Holders of the Notes, subject to exceptions set forth in Section 902 of the Base Indenture. Subject to the provisions of the Indenture, the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may, on behalf of the Holders of all of the Notes, waive any past default or Event of Default with respect to the Notes, subject to exceptions set forth in the Indenture.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Issuer and the Holder of the Notes, the obligation of the Issuer, which is absolute and unconditional, to pay the principal of, premium, if any, on and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture prescribed.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

The Notes are issuable in fully registered form, without coupons, in minimum denominations of $2,000 principal amount and any multiple of $1,000 in excess thereof. At the office or agency of the Issuer referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, Notes may be transferred or may be exchanged for a like aggregate principal amount of Notes of any other authorized denominations.

The Notes are not subject to redemption through the operation of any sinking fund.

Except to the extent expressly provided in Article Sixteen of the Base Indenture, no recourse for the payment of the principal of or any premium or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Issuer in the Indenture or any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any past, present or future general partner, limited partner, member, employee, incorporator, controlling person, stockholder, officer, director or agent, as such, of the Issuer or of any of the Issuer’s predecessors or successors, either directly or through the Issuer, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Notes by the Holders thereof and as part of the consideration for the issue of the Notes.
