Date: April 21, 2016 
 Interest Payment Dates: April 21 and October 21 

Maturity Date: April 21, 2019 
 Interest Rate: 1.625% 

AUTOZONE, INC., a Nevada corporation (hereinafter called the “Company”, which term includes any successor corporation under the
Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of two hundred fifty million dollars ($250,000,000) (the “Principal Amount”) on the Maturity
Date shown above, except as provided below, and to pay interest thereon at the rate per annum shown above. (Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.) The Company
will pay interest semiannually on the Interest Payment Dates, commencing on October 21, 2016. Interest on this Note will accrue from the most recent Interest Payment Date to which interest has been paid or duly provided for or, if no interest
has been paid or duly provided for, from the Original Issue Date shown above. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the person in whose name
this Note (or one or more predecessor Securities) is registered at the close of business on the regular record date for such interest, which shall be the April 6 or the October 6 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. 

 Payment of the principal of and interest on this Note will be made at the Corporate Trust Office
of the Trustee in New York, New York, 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. 

If the Company defaults in a payment of interest on this Note, it shall pay the defaulted interest, plus, to the extent permitted by law, any
interest payable on the defaulted interest, to the persons who are Securityholders of this Note on a subsequent special record date. The Company shall fix that record date and payment date. At least ten (10) days before that record date, the
Company shall mail to the Trustee and to each Securityholder a notice that states that record date, the payment date and the amount of interest and any interest thereon to be paid. The Company may pay defaulted interest and any interest thereon in
any other lawful manner. 
 This Note is one of a duly authorized issue of securities of the Company (the “Securities”), of the
Series hereinafter specified, all issued under and pursuant to an indenture, dated as of August 8, 2003, together with the Officers’ Certificate dated April 21, 2016 (the “Officers’ Certificate”), establishing the terms
of the Notes (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor in interest to Bank One Trust Company, N.A.), as Trustee (the “Trustee”), to which Indenture and all 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 Company and Holders of the Securities. The aggregate principal amount of
Securities that may be authenticated and delivered under the Indenture is unlimited. The Securities may be issued in one or more Series, which different Series may be issued in various aggregate principal amounts, may mature at different times, may
bear interest, if any, at different rates, may be subject to different redemption provisions, if any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to different covenants and Events of Default and may
otherwise vary as in the Indenture provided. This Note is one of a Series designated as the “1.625% Senior Notes due 2019” of the Company (herein referred to as the “Notes”), initially issued in an aggregate principal amount of
two hundred fifty million dollars ($250,000,000). The Company may from time to time, without notice to or the consent of the holders of the Notes, create and issue additional Notes ranking equally and ratably with the Notes and otherwise identical
in all respects, except for the issue price, the issue date, the payment of interest accruing prior to the issue date of such additional Notes and, in some cases, the first payment of interest following the issue date of such additional Notes and
the initial interest accrual date thereof, so that such further Notes shall be consolidated and form a single Series with the Notes. 
 The
Notes constitute senior unsecured debt obligations of the Company and rank equally in right of payment among themselves and with all other existing and future senior, unsecured and unsubordinated debt obligations of the Company. 

In accordance with and subject to the provisions of the Officers’ Certificate, the Holders of the Notes may require that the Company
repurchase the Notes if a Change of Control Triggering Event has occurred. 

 The Notes will be redeemable at the option of the Company at any time, in whole or from time to
time in part. The redemption price will equal accrued and unpaid interest on the principal amount being redeemed to the redemption date plus the greater of (i) 100% of the principal amount of such Notes to be redeemed and (ii) the sum of
the present values of the remaining scheduled payments of principal and interest on such Notes being redeemed (not including any portion of such payments of interest accrued to the date of redemption) discounted to the date of redemption on a
semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 15 basis points, as determined in good faith by the Company. 

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of the Notes to
be redeemed. Notwithstanding anything to the contrary in Section 4.4 of the Indenture, notice of any redemption of Notes need not set forth the redemption price but only the manner of calculation thereof. The Company shall give the Trustee
notice of the amount of the redemption price for any such redemption promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. In connection with any redemption, unless the Company defaults in payment
of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes or portions of the Notes called for redemption. 

“Adjusted Treasury Rate” means, with respect to any date of redemption, the rate per annum equal to the semiannual equivalent yield
to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such date of redemption. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity
comparable to the remaining term of the Notes to be redeemed that would be used, at the time of selection and under customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such
Notes. 
 “Comparable Treasury Price” means, with respect to any date of redemption, the average of the Reference Treasury Dealer
Quotations for such date of redemption, after excluding the highest and lowest Reference Treasury Dealer Quotations, or if the Quotation Agent obtains fewer than four Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer
Quotations. 
 “Quotation Agent” means one of the Reference Treasury Dealers appointed by the Company. 

“Reference Treasury Dealer” means each of (i) Barclays Capital Inc., Merrill Lynch, Pierce, Fenner & Smith
Incorporated and a Primary Treasury Dealer (defined herein) selected by SunTrust Robinson Humphrey, Inc. and their respective successors; and (ii) any other primary U.S. government securities dealer in New York City (each a “Primary
Treasury Dealer”) selected by the Company. If any of the foregoing ceases to be a Primary Treasury Dealer, the Company must substitute another Primary Treasury Dealer. 

 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury
Dealer and any date of redemption, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation
Agent by the Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day before the date of redemption. 
 The
Notes will not be subject to, or have the benefit of, any sinking fund. 
 In case an Event of Default (as defined in the Indenture) with
respect to the Notes shall have occurred and be continuing, the principal hereof may be declared, or shall become, due and payable, in the manner, with the effect and subject to certain conditions set forth in the Indenture. The Indenture provides
that, subject to certain conditions therein set forth, any such declaration of acceleration and its consequences may be waived by the Holders of a majority in principal amount of the outstanding Notes. 

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of at least a majority in principal
amount of the outstanding Notes to be affected thereby, as provided in the Indenture, to enter into 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 or modifying in any manner the rights of the Holders of the Notes; and the Indenture also contains provisions allowing the Holders of at least a majority in principal amount of the outstanding Notes to waive compliance with
any provision of the Indenture or this Note; provided, however, that no such supplemental indenture or amendment or waiver may, without the consent of each Holder of Notes to be affected (a) reduce the amount of Notes whose
Holders must consent to an amendment, supplement or waiver; (b) reduce the rate of, change the method of determination of or extend the time for payment of interest (including default interest) on any Note; (c) reduce the principal or
change the Stated Maturity of any Note; (d) make any change in the provisions concerning waivers of Events of Default by Holders or the rights of Holders to recover the principal of or interest on any Note; (e) waive a Default or Event of
Default in the payment of the principal of or interest on any Note (except a rescission of acceleration of the Notes by the Holders of at least a majority in principal amount of the outstanding Notes and a waiver of the payment default that resulted
from such acceleration); (f) make the principal of or interest on any Note payable in any currency other than that stated in the Note; (g) make any change in Sections 7.8, 7.13, or 10.3 of the Indenture; or (h) waive a redemption
payment with respect to any Note. The Indenture also provides that the Holders of not less than a majority in principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past Default under the Indenture with
respect to the Notes and its consequences, except a Default (i) in the payment of the principal of or interest on any Note (provided, however, that the Holders of a majority in principal amount of the outstanding Notes may rescind an
acceleration and its consequences, including any related payment default that resulted from such acceleration) or (ii) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each
outstanding Notes affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon. Any such waiver by the Holders of the Notes shall be conclusive and binding upon the Holder of this Note and upon all future Holders and owners of this Note and of any Note issued
upon the transfer hereof or in exchange or substitution hereof. 

 No reference herein to the Indenture and no provision of this Note 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 this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable by the Holder
hereof on the register of the Company, upon due presentment of this Note for registration of transfer at the office of the Registrar, or at the office of any co-registrar duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to, the Company and the Registrar or any such co-registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and for an equal principal amount
will be issued to the designated transferee or transferees. 
 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 transfer tax or similar governmental charge payable in connection therewith. 

The Notes are issuable only as registered Notes without coupons in denominations equal to $2,000 or an integral multiple of $1,000 in excess
thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for new Notes of any authorized denominations of an equal principal amount as requested by the Holder surrendering the same. 

Notwithstanding the other provisions of the Indenture, payment of the principal of and interest, if any, on any Note represented by a Global
Security shall be made to the Holder thereof. The Company and the Trustee understand that interest on any such Global Security will be disbursed or credited by the Depository to the persons having beneficial ownership thereof pursuant to a
book-entry or other system maintained by the Depository. 
 Except as provided in the foregoing paragraph, the Company, the Trustee and any
Agent shall treat a person as the Holder of such principal amount of outstanding Notes represented by a Global Security as shall be specified in a written statement of the Depository with respect to such Global Security, for purposes of obtaining
any consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture. 
 The Holder of this Note
shall not have recourse for the payment of principal of or interest on this Note or for any claim based on this Note or the Indenture against any director, officer, employee or stockholder, as such, of the Company. By acceptance of this Note, the
Holder waives and releases all such liability. 
 THE INDENTURE AND THIS NOTE SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO THE CONFLICT OF LAWS PROVISIONS THEREOF. 

 All terms used but not defined in this Note which are defined in the Indenture shall have the
meanings assigned to them in the Indenture. 
 Unless the certificate of authentication has been executed by manual signature of the
Trustee, this Note shall not be valid. 

 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed manually or in
facsimile.
