on the relevant Regular Record Date, and such Defaulted Interest shall instead be payable either (i) to the Person in whose name such 3.60% Note is registered on the 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 3.60% Note not less than 10 days prior to such Special Record Date or (ii) at any time in any other lawful manner in accordance with the Indenture. 

(c) If any Interest Payment Date or Stated Maturity falls on a day that is not a Business Day, the required payment shall be made on the next

than 60% of the sum of (without duplication) (i) the Total Assets of the Company and its Subsidiaries as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case
may be, most recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Indebtedness and (ii) the purchase price of any real estate assets or
mortgages receivable acquired, and the 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 Indebtedness), by the Company or any

 8 

 (b) In addition to the limitation set forth in subsection (a) of this Section 2.4, the
Company will not, and will not permit any Subsidiary to, incur any Indebtedness if the ratio of Consolidated Income Available for Debt Service to the Annual Debt Service Charge for the four consecutive fiscal quarters most recently ended prior to
the date on which such additional Indebtedness is to be incurred shall have been less than 1.5:1, on a pro forma basis after giving effect thereto and to the application of the proceeds therefrom, and calculated on the assumption that (i) such
Indebtedness and any other Indebtedness incurred by the Company and its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Indebtedness, had occurred at the
beginning of such period; (ii) the repayment or retirement of any other Indebtedness by the Company and its Subsidiaries since the first day of such four-quarter period had been repaid or retired at the beginning of such period (except that, in
making such computation, the amount of Indebtedness under any revolving credit facility shall be computed based upon the average daily balance of such Indebtedness during such period); (iii) in the case of Acquired Indebtedness or Indebtedness
incurred in connection with any acquisition since the first day of such four-quarter period, the related acquisition had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition being included in
such pro forma calculation; and (iv) in the case of any acquisition or disposition by the Company or its Subsidiaries of any asset or group of assets since the first day of such four-quarter period, whether by merger, stock purchase or sale, or
asset purchase or sale, such acquisition or disposition or any related repayment of Indebtedness 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. 
 (c) In addition to the limitations set forth in subsections (a) and (b) of this Section 2.4, the
Company will not, and will not permit any Subsidiary to, incur any Indebtedness secured by any Encumbrance upon any of the property of the Company or any Subsidiary if, immediately after giving effect to the incurrence of such additional
Indebtedness and the application of the proceeds thereof, the aggregate principal amount of all outstanding Indebtedness of the Company and its Subsidiaries (determined on a consolidated basis in accordance with GAAP) which is secured by any
Encumbrance on property of the Company or any Subsidiary is greater than 40% of the sum of (without duplication) (i) the Total Assets of the Company and its Subsidiaries as of the end of the calendar quarter covered in the Company’s Annual
Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Indebtedness
and (ii) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent that such proceeds were not used to acquire real estate assets or mortgages
receivable or used to reduce Indebtedness), by the Company or any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Indebtedness. 

(d) The Company and its Subsidiaries may not at any time own Total Unencumbered Assets equal to less than 150% of the aggregate outstanding
principal amount of the Unsecured Indebtedness of the Company and its Subsidiaries on a consolidated basis. 

  
 9 

 (e) For purposes of this Section 2.4, Indebtedness shall be deemed to be
“incurred” by the Company or a Subsidiary whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.

the greater of (i) 100% of the principal amount of the 3.60% Notes being redeemed plus accrued and unpaid interest thereon to, but not including, the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to such 3.60% Notes;
provided, however, that if the Company redeems the 3.60% Notes on or after the Par Call Date, the redemption price will equal 100% of the principal amount of the 3.60% Notes to be redeemed plus accrued and unpaid interest thereon to, but not
including, the Redemption Date (such amount computed under this Section 2.5, the “Redemption Price”). Notice of any optional redemption of all or any portion of the 3.60% Notes then outstanding shall be given to Holders at their

3.60% NOTE DUE 2026 
 NATIONAL
RETAIL PROPERTIES, INC., a corporation duly organized and existing under the laws of the State of Maryland (herein referred to as the “Company” which term shall include any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, upon presentation, the principal sum of THREE HUNDRED FIFTY MILLION AND 00/100THS DOLLARS ($350,000,000.00), as may be revised by the Schedule of
Increases or Decreases in Global Security attached hereto, on December 15, 2026 and to pay interest on the outstanding principal amount thereon from December 12, 2016, or from the immediately preceding Interest Payment Date to which
interest has been paid or duly provided for, semi-annually in arrears on June 15 and December 15 in each year, commencing June 15, 2017, at the rate of 3.60% per annum, until the entire principal hereof is paid or made available
for payment. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security is registered at the close of business on the Regular
Record Date for such interest, which shall be the June 1 or December 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for shall
forthwith cease to be payable to the Holder on such Regular Record Date, and may either be paid to the Person in whose name 

  
 - 1 - 

 
this Security is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
the Securities not more than 15 days and not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be
listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Payment of the principal of and interest on this Security will be made at the office or agency maintained for that purpose in the City of
St. Paul, Minnesota, or elsewhere as provided in the Indenture, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the
option of the Company, payments of principal and interest on the 3.60% Notes (other than payments of principal and interest due at Stated Maturity) may be made (i) by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or (ii) by wire transfer to an account of the Person entitled thereto located within the United States; provided, that such Person owns 3.60% Notes in an aggregate principal amount of at least
$1,000,000 and such Person makes a written request therefor for the appropriate Interest Payment Date. 
 Securities of this series are one
of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of March 25, 1998 (as supplemented, herein called the
“Indenture”), between the Company and U.S. Bank National Association, as successor trustee to Wachovia Bank, National Association (formerly First Union National Bank) (herein called the “Trustee,” which term includes any
successor trustee under the Indenture), to which the Indenture and all indentures supplemental thereto, including, the Fifteenth Supplemental Indenture thereto, dated as of December 12, 2016, between the Company and the Trustee, reference is
hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are authenticated and delivered.
This Security is one of the series designated in the first page thereof, initially having an aggregate principal amount equal to $350,000,000; provided, that the Company may, without the consent of the Holders of the then Outstanding 3.60%
Notes, “reopen” this series of Securities so as to increase the aggregate principal amount of 3.60% Notes Outstanding in compliance with the procedures set forth in the Indenture, including Sections 3.1 and 3.3 thereof, so long as any such
additional notes have the same tenor and terms (including, without limitation, rights to receive accrued and unpaid interest) as the 3.60% Notes then Outstanding. 

Securities of this series may be redeemed prior to September 15, 2026 (which is the date three months prior to the Stated Maturity), at
any time at the option of the Company, in whole or in part from time to time, upon notice of not more than 60 nor less than 15 days prior to the Redemption Date, at a redemption price equal to the greater of (i) 100% of the principal amount of
the Securities being redeemed plus accrued and unpaid interest thereon to, but not including, the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to such Securities; provided, however, that if the Company
redeems the 3.60% Notes on or after September 15, 2026, the redemption price will equal 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest thereon to, but not including, the Redemption Date. 

  
 - 2 - 

 The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness
of the Company on this Security and (ii) certain restrictive covenants and the related defaults and Events of Default applicable to the Company, in each case, upon compliance by the Company with certain conditions set forth in the Indenture,
which provisions apply to this Security. 
 If an Event of Default with respect to the Securities shall occur and be continuing, the
principal of the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. 
 As provided in
and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless
(i) such Holder shall have previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities, (ii) the Holders of not less than 25% in principal amount of the Securities of this series at the
time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity and (iii) the Trustee shall not have received from the Holders
of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any interest on or after the respective due dates expressed herein. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities of each series of Securities then Outstanding affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by
the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security. 
 No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on (or Make-Whole Amount, if any, with respect to) this Security at the times, place and rate, and in the
coin or currency, herein prescribed. 

  
 - 3 - 

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer
of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any Place of Payment where the principal of and interest on (or Make-Whole Amount, if
any, with respect to) this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or his attorney duly authorized
in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000
thereafter. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as
requested by the Holder surrendering the same. 
 This 3.60% Note is a Global Security. As provided in and subject to the provisions of the
Indenture, definitive Securities shall be issued to all owners of beneficial interests in a Global Security in exchange for such interests if: (1) the depositary with respect to the 3.60% Notes (which shall initially be DTC) notifies the
Company that it is unwilling or unable to continue as depositary for such Global Security or the depositary ceases to be a clearing agency registered under the Exchange Act, at a time when the depositary is required to be so registered in order to
act as depositary, and in each case a successor depositary is not appointed by the Company within 90 days of such notice; (2) an Event of Default has occurred and is continuing and the Security Registrar has received a request from the
depositary or (3) the Company executes and delivers to the Trustee and Security Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable. In connection with the exchange of an entire Global Security for
definitive Securities pursuant to this paragraph, such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute and the Trustee shall authenticate and deliver, to each beneficial owner
identified by the depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of definitive Securities of authorized denominations. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent of the Company or the Trustee shall be affected by notice to the contrary. 
 No recourse under or upon any
obligation, covenant or agreement contained in the Indenture or in this Security, or because of any indebtedness evidenced hereby or thereby, shall be had against any promoter, as such, or against any past, present or future shareholder, officer or

  
 - 4 - 

 
director, as such, of the Company or of any successor, either directly or through the Company or any successor, 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 this Security by the Holder thereof and as part of the consideration for the issue of the Securities of
this series. 
 All capitalized terms used in this Security which are used herein but not defined herein shall have the meanings assigned to
them in the Indenture. 
 THE INDENTURE AND THE SECURITIES, INCLUDING THIS SECURITY, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK. 
 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures, the Company has caused “CUSIP” numbers to be printed on the Securities of this series as a convenience to the Holders of such Securities. No representation is made as to the correctness or accuracy of such CUSIP numbers as
printed on the Securities, and reliance may be placed only on the other identification numbers printed hereon. 
 Unless the certificate of
authentication hereon has been executed by or on behalf of the Trustee by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.
