WHEREAS, the Issuer has heretofore delivered to the Trustee an Indenture dated as of May 9, 2014 (the “Base Indenture”), providing for the issuance by the Issuer from time to time of its senior debt securities evidencing its unsecured and unsubordinated indebtedness (the “Securities”).

WHEREAS, Section 2.01 of the Base Indenture provides for various matters with respect to any series of Securities issued under the Base Indenture to be established in an indenture supplemental to the Base Indenture.

WHEREAS, Section 9.01(i) of the Base Indenture provides for the Issuer and the Trustee to enter into an indenture supplemental to the Base Indenture to establish the form or terms of Securities of any series as provided by Sections 2.01 and 2.02 of the Base Indenture.

WHEREAS, the Board of Trustees of the Issuer, has duly adopted resolutions authorizing the Issuer to execute and deliver this Third Supplemental Indenture and issue the Notes; and

WHEREAS, all of the conditions and requirements necessary to make this Third Supplemental Indenture, when duly executed and delivered, a valid and binding agreement in accordance with its terms and for the purposes herein expressed, have been performed and fulfilled.

NOW, THEREFORE, THIS THIRD SUPPLEMENTAL INDENTURE WITNESSETH:

For all purposes of this Third Supplemental Indenture, except as otherwise expressly provided for or unless the context otherwise requires:

(1) Capitalized terms used but not defined herein shall have the respective meanings assigned to them in the Base Indenture; provided that, where a term is defined both in this Third Supplemental Indenture and in the Base Indenture, the meaning given to such term in this Third Supplemental Indenture shall control for purposes of this Third Supplemental Indenture and (in respect of the Notes but not any other series of Securities) the Base Indenture; and

(2) All references herein to Articles and Sections, unless otherwise specified, refer to the corresponding Articles and Sections of this Third Supplemental Indenture.

“Acquired Debt” means Debt of a Person (1) existing at the time such Person is merged or consolidated with or into the Issuer or any of its Subsidiaries or becomes a Subsidiary of the Issuer; or (2) assumed by the Issuer or any of its Subsidiaries in connection with the acquisition of assets from such Person. Acquired Debt shall be deemed to be incurred on the date the acquired Person is merged or consolidated with or into the Issuer or any of its Subsidiaries or becomes a Subsidiary of the Issuer or the date of the related acquisition, as the case may be.

If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For the purposes of calculating the Adjusted Treasury Rate, the most recent Statistical Release published at least two Business Days prior to the Redemption Date (or in the case of satisfaction and discharge or defeasance, two Business Days prior to the date funds are deposited with the Trustee to pay and discharge the entire indebtedness of the Notes) shall be used.

“Debt” means, with respect to any Person, any indebtedness of such Person in respect of, without duplication, (1) such Person’s borrowed money or such Person’s indebtedness evidenced by bonds, notes, debentures or similar instruments, in each case, whether or not such Debt is secured by any Lien existing on any property or assets owned by such Person; (2) any other indebtedness secured by any Lien on any property or asset owned by such Person, but only to the extent of the lesser of (a) the amount of indebtedness so secured and (b) the fair market value (determined in good faith by the board of trustees of such Person or, in the case of a Guarantor, by the Issuer’s Board of Trustees or a duly authorized committee thereof) of the property subject to such Lien; (3) reimbursement obligations, contingent or otherwise, in connection with any letters of credit actually issued or amounts representing the balance deferred and unpaid of the purchase price of any property except any such balance that constitutes an accrued expense or trade payable; or (4) any lease of property by such Person as lessee which is required to be reflected on such Person’s balance sheet as a finance lease in accordance with United States generally accepted accounting principles.

THE NOTES SECTION

Section 2.1 Title of the Securities.

There shall be a series of Securities designated the “2.375% Senior Notes due 2031” (the “Notes”).

Section 2.2 Forms Generally.

The Notes shall be issued in the form of a Global Security and DTC shall be the initial Depositary for the Notes. The Notes and the Trustee’s certificate of authentication shall be in the forms set forth in Exhibit A attached hereto, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the Officers executing such Notes, as evidenced by their execution of the Notes. Any portion of the text of any Note may be set forth on the reverse thereof, with an appropriate reference thereto on the face of the Note.

The Notes shall be printed, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner, as determined by the Officers of the Issuer executing such Notes, as evidenced by their manual or facsimile execution of such Notes.

In accordance with Section 2.04 of the Base Indenture, upon the execution of this Third Supplemental Indenture, and from time to time thereafter, Notes may be executed by the Issuer and delivered to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver Notes upon a written order of the Issuer conforming to the signatory requirements of an Officers’ Certificate under Section 1.01 of the Base Indenture (an “Authentication Order”), without any further action by the Issuer hereunder.

Section 2.3 Limitation on Initial Aggregate Principal Amount; Further Issuances.

The aggregate principal amount of the Initial Notes shall be limited to $400,000,000, except as provided in Sections 2.06 and 2.07 of the Base Indenture. The Issuer may, from time to time, subject to Section 2.6 hereof and applicable law, create and issue Additional Notes under the Indenture.

Section 2.4 Interest and Interest Rates; Maturity Date of Notes.

The Notes shall bear interest at 2.375% per annum from August 30, 2021 or from the immediately preceding Interest Payment Date (as defined below) to which interest has been paid, payable semi-annually in arrears on April 1 and October 1 of each year, commencing April 1, 2022 (each, an “Interest Payment Date”), to the persons (the “Holders”) in whose name the applicable Notes are registered in the Security Register at the close of business on the March 15

or September 15 immediately preceding such Interest Payment Date (regardless of whether such day is a Business Day), as the case may be (each, a “Record Date”). Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. Defaulted Interest, if any, shall forthwith cease to be payable to the Holder on the applicable Record Date and may either be paid to the person in whose name such Note is registered at the close of business on a special record date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to the Holder of such Note not less than ten days prior to such special record date, or may be paid at any time in any other lawful manner, as more particularly described in the Base Indenture. The Notes shall mature on October 1, 2031 (the “Maturity Date”).

Section 2.5 Issuance of Additional Notes.

The Issuer will be entitled, upon delivery to the Trustee of an Officers’ Certificate, Opinion of Counsel and Authentication Order, subject to its compliance with Section 2.6 hereof, to issue Additional Notes under the Indenture that will have identical terms to and the same CUSIP number as the Initial Notes issued on the date of this Third Supplemental Indenture other than with respect to the date of issuance, issue price, the date from which interest initially accrues on such Additional Notes, and if applicable, the first Interest Payment Date. The Initial Notes and any such Additional Notes will constitute a single series of debt securities, and in circumstances in which the Indenture provides for the Holders of Notes to vote or take any action, the Holders of Initial Notes and the Holders of any such Additional Notes will vote or take the action as a single class.

With respect to any Additional Notes, the Issuer will set forth in a resolution of its Board of Trustees and an Officers’ Certificate, a copy of each of which will be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to the Indenture; and

(2) the issue price, the issue date and the CUSIP number of such Additional Notes.

Section 2.6 Limitations on Incurrence of Debt.

(a) Limitation on Total Outstanding Debt. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt (including, without limitation, Acquired 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 aggregate principal amount of all of the Issuer’s and its Subsidiaries’ outstanding Debt (determined on a consolidated basis in accordance with United States generally accepted accounting principles) is greater than 60% of the sum of the following (without duplication): (1) the Issuer’s and its Subsidiaries’ Total Assets as of the last day of the then most recently ended fiscal quarter and (2) the aggregate purchase price of any real estate assets or mortgages receivable acquired, and the aggregate amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Issuer or any Subsidiary of the Issuer

since the end of such fiscal quarter, including the proceeds obtained from the incurrence of such additional Debt.

(b) Limitation on Secured Debt. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt (including, without limitation, Acquired Debt) secured by any Lien on any of the Issuer’s or any of its Subsidiaries’ property or assets, whether owned on the date of this Third Supplemental Indenture or subsequently acquired, 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 aggregate principal amount of all of the Issuer’s and its Subsidiaries’ outstanding Debt (determined on a consolidated basis in accordance with United States generally accepted accounting principles) which is secured by a Lien on any of the Issuer’s or its Subsidiaries’ property or assets is greater than 40% of the sum of (without duplication): (1) the Issuer’s and its Subsidiaries’ Total Assets as of the last day of the then most recently ended fiscal quarter; and (2) the aggregate purchase price of any real estate assets or mortgages receivable acquired, and the aggregate amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of such fiscal quarter, including the proceeds obtained from the incurrence of such additional Debt.

(1) The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt (including, without limitation, Acquired Debt) if the ratio of Consolidated Income Available for Debt Service to Annual Debt Service Charge for the period consisting of the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred shall have been less than 1.5:1 on a pro forma basis after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt (determined on a consolidated basis in accordance with United States generally accepted accounting principles), and calculated on the following assumptions:

(A) such Debt and any other Debt (including, without limitation, Acquired Debt) incurred by the Issuer or any of its Subsidiaries since the first day of such four- quarter period 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 period;

(B) the repayment or retirement of any other Debt of the Issuer or any of its Subsidiaries since the first day of such four-quarter period had occurred on the first day of such period (except that, in making this computation, the amount of Debt under any revolving credit facility, line of credit or similar facility will be computed based upon the average daily balance of such Debt during such period); and

(C) in the case of any acquisition or disposition by the Issuer or any of its Subsidiaries of any asset or group of assets with a fair market value in excess of $1.0 million since the first day of such four-quarter period, 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 period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation.

(2) If the Debt giving rise to the need to make the calculation described in Section 2.6(c)(1) hereof or any other Debt incurred after the first day of the relevant four-quarter period bears interest at a floating rate, then, for purposes of calculating the Annual Debt Service Charge, the interest rate on such Debt will be computed on a pro forma basis by applying the average daily rate which would have been in effect during the entire four-quarter period to the greater of the amount of such Debt outstanding at the end of such period or the average amount of such Debt outstanding during such period. For purposes of this Section 2.6(c) hereof, Debt will be deemed to be incurred by the Issuer or any of its Subsidiaries whenever the Issuer or any of its Subsidiaries shall create, assume, guarantee (on a non-contingent basis) or otherwise become liable in respect thereof.

(d) Maintenance of Total Unencumbered Assets. The Issuer and its Subsidiaries will not have at any time Total Unencumbered Assets of less than 150% of the aggregate principal amount of all of the Issuer’s and its Subsidiaries’ outstanding Unsecured Debt determined on a consolidated basis in accordance with United States generally accepted accounting principles.

Section 2.7 Insurance.

The Issuer will, and will cause of each of its Subsidiaries to, keep in force upon all of the Issuer’s and each of its Subsidiaries’ properties and operations insurance policies carried with responsible insurance companies in such amounts and covering all such risks as is customary in the industry in which the Issuer and its Subsidiaries do business in accordance with prevailing market conditions and availability.

Section 2.8 Maintenance of Properties.

The Issuer will cause all of its and its Subsidiaries’ properties used or useful in the conduct of the business of the Issuer or any of its Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and the Issuer will cause all necessary repairs, renewals, replacements, betterments and improvements to be made, all as in the Issuer’s judgment may be necessary in order for the Issuer to at all times properly and advantageously conduct its business carried on in connection with such properties.

Section 2.9 Payment of Taxes and Other Claims.

The Issuer will pay or discharge or cause to be paid or discharged before it becomes delinquent: (i) all taxes, assessments and governmental charges levied or imposed on the Issuer or any of its Subsidiaries or on its or any such Subsidiary’s income, profits or property; and (ii) all lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon its property or the property of any of its Subsidiaries; provided, however, that the Issuer will not be required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith.

Section 2.10 Optional Redemption. The provisions of this Section 2.10 apply solely with respect to the Notes and all references to Holders in this Section 2.10 shall be solely to Holders of the Notes. The Notes shall be redeemable at the Company’s option prior to the Maturity Date in accordance with this Section 2.10 and Sections 3.01, 3.02 and 3.03 of the Base Indenture (as amended by this Section 2.10).

(a) The Issuer shall have the right to redeem the Notes at its option and in its sole discretion at any time or from time to time prior to the Maturity Date, in whole or in part. The redemption price (“Redemption Price”) will equal the greater of (i) 100% of the principal amount of the Notes to be redeemed or (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) that would be due if such Notes matured 90 days prior to the Maturity Date (the “Par Call Date”) but for the redemption thereof discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 20 basis points (0.200% or twenty one-hundredths of one percent), plus, in the case of both clauses (i) and (ii), accrued and unpaid interest on the principal amount of the Notes being redeemed to, but excluding, the applicable Redemption Date; provided, however, that 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, 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). Notwithstanding the foregoing, if the Notes are redeemed on or after July 1, 2031, the Redemption Price will be equal to 100% of the principal amount of the Notes being redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date.

(b) The Issuer shall not redeem the Notes pursuant to Section 2.10(a) hereof on any date if the principal amount of the Notes has been accelerated, and such an acceleration has not been rescinded or cured 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).

(c) Section 3.02 of the Base Indenture is hereby amended with respect to the Notes only by changing, in the first sentence thereof, the number “30” to the number “15”.

Section 2.11 Guarantees.

(b) In accordance with Section 15.02 of the Base Indenture, each Guarantor shall also execute a notation of Guarantee substantially in the form of Exhibit B supplemental hereto, which shall be endorsed on each Note authenticated and delivered by the Trustee.

The provisions of Sections 3.04, 3.05 and 3.06 of the Base Indenture shall not be applicable to the Notes.

Section 2.13 Conflict with Trust Indenture Act.

If any provision of the Indenture limits, qualifies or conflicts with another provision of the Indenture, which is required to be included in the Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control to the extent it is applicable.

Section 2.14 Covenant Defeasance. Section 12.03 of the Base Indenture is hereby amended with respect to the Notes only by changing, in the first sentence thereof, the reference to “Section 4.05 and 4.08 and Article X hereof” to “Section 4.05, Section 5.04 and Article X of the Base Indenture and Sections 2.6, 2.7, 2.8 and 2.9 of the Third Supplemental Indenture.”
