Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On April 18, 2019, AutoZone, Inc. (the “Company”) completed the sale of $300 million aggregate principal amount of its 3.125% Notes due 2024 (the “2024 Notes”) and $450 million aggregate principal amount of its 3.750% Notes due 2029 (the “2029 Notes” and, together with the 2024 Notes, the “Notes”). The 2024 Notes bear interest at a fixed rate equal to 3.125% per year, payable semi-annually and the 2029 Notes bear interest at a fixed rate equal to 3.750% per year, payable semi-annually.

The Notes were issued pursuant to an Indenture dated as of August 8, 2003 (the “Indenture”), between the Company and Regions Bank, as successor in interest to The Bank of New York Mellon Trust Company, N.A., as successor in interest to Bank One Trust Company, N.A., as trustee, and were offered and sold pursuant to the Company’s shelf registration statement filed with the Securities and Exchange Commission (the “Commission”) on April 4, 2019, on Form S-3 (File No. 333-230719), as supplemented by a prospectus supplement dated April 4, 2019, filed with the Commission on April 5, 2019. Pursuant to the Indenture, the Company executed an Officers’ Certificate dated April 18, 2019 setting forth the terms of the 2024 Notes (the “2024 Notes Officers’ Certificate”) and an Officers’ Certificate dated April 18, 2019 setting forth the terms of the 2029 Notes (the “2029 Notes Officers’ Certificate” and, together with the 2024 Notes Officers’ Certificate, the “Officers’ Certificates”).

The Company will pay interest on the Notes on April 18 and October 18 of each year, beginning October 18, 2019. The 2024 Notes will mature on April 18, 2024, and the 2029 Notes will mature on April 18, 2029. The Notes will be senior unsecured debt obligations of the Company and will rank equally with the Company’s other senior unsecured liabilities and senior to any future subordinated indebtedness of the Company. The Notes are subject to customary covenants restricting the Company’s ability, subject to certain exceptions, to incur debt secured by liens, to enter into sale and leaseback transactions or to merge or consolidate with another entity or sell substantially all of its assets to another person. The Indenture provides for customary events of default and further provides that the trustee or the holders of 25% in aggregate principal amount of the outstanding series of Notes may declare such Notes immediately due and payable upon the occurrence of any event of default after expiration of any applicable grace period.

The Company may redeem the Notes at the Company’s option, at any time in whole or from time to time in part, on not less than 30 nor more than 60 days’ notice, at the redemption prices described in the applicable Officer’s Certificate. If a change of control, as defined in the applicable Officers’ Certificate, occurs, unless the Company has exercised its option to redeem the Notes, holders of the Notes may require the Company to repurchase the Notes at the prices described in the applicable Officers’ Certificate.

The above description of the Officers’ Certificates and the Notes is qualified in its entirety by reference to the Officers’ Certificates pursuant to the Indenture setting forth the terms of the Notes, and the form of the Notes, copies of which are attached hereto as Exhibits 4.1, 4.2, 4.3 and 4.4, respectively.

OFFICERS’ CERTIFICATE

PURSUANT TO SECTION 3.2 OF THE INDENTURE

April 18, 2019

A. Pursuant to resolutions of the Board of Directors of AutoZone, Inc., a Nevada corporation (the “Company”), adopted at a duly noticed and held meeting of the Board of Directors on September 25, 2018 (the “Resolutions”), the undersigned, Brian L. Campbell, Vice President and Treasurer of the Company, and William T. Giles, Executive Vice President and Chief Financial Officer of the Company certify that pursuant to the Resolutions and Section 3.2 of the Indenture, dated as of August 8, 2003 (the “Indenture”), between the Company and Regions Bank, as successor in interest to 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”), there is hereby established a series of Securities (as that term is defined in the Indenture), the terms and form of which shall be as follows (capitalized terms not defined herein shall have the meanings assigned to them in the Indenture):

(a) The title of the series of the Securities shall be “3.125% Senior Notes due 2024” (the “Notes”).

(b) The Notes shall be issued at a price of 99.711% of the principal amount thereof.

(c) The aggregate principal amount of the Notes that may be authenticated and delivered under the Indenture (except for Notes authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 3.7, 3.8, 3.11, 4.7 or 10.6 of the Indenture) initially shall be $300,000,000. The Company may, without the consent of the Holders of the Notes, create and issue additional Notes ranking equally and ratably with the Notes and otherwise identical to the Notes in all respects, except for 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 form a single series with the Notes.

(d) The principal amount of the Notes shall be payable in full on April 18, 2024, subject to and in accordance with the provisions of the Indenture.

(e) The Notes shall bear interest at the rate of 3.125% per annum from April 18, 2019, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, payable semiannually on April 18 and October 18 of each year (each an “Interest Payment Date”), commencing on October 18, 2019 until the principal amount of the Notes has been paid or duly provided for. The April 3 and October 3 (whether or not a Business Day), as the case may be, next preceding an Interest Payment Date, shall be a “Regular Record Date” for the interest payable on such Interest Payment Date.

(f) The principal of and interest on the Notes shall be payable at the Corporate Trust Office of the Trustee in Atlanta, Georgia.

1

(g) The Notes will be redeemable at the option of the Company, at any time in whole or from time to time in part. If the Notes are redeemed before March 18, 2024 (one month prior to the maturity date of the Notes) (the “Par Call Date”), the redemption price will equal 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 to be redeemed that would have been due if the Notes matured on the Par Call Date (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, plus accrued and unpaid interest thereof, if any, to but excluding, the date of redemption. If the Notes are redeemed on or after the Par Call Date, the redemption price for the Notes will equal 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, thereon, if any, to, but excluding the date of the redemption.

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 occurring prior prior to the Par Call Date 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 year 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 that 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 of such Reference Treasury Dealer Quotations, or if the Quotation Agent obtains fewer than four such 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”) the Company selects. 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 such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such date of redemption.

2

(h) The Notes will be issued only in registered form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

(i) The Notes shall be issuable in whole or in part in the form of one or more Global Securities. Such Global Securities may be exchanged in whole or in part for individual Securities in definitive form only on the terms and conditions set forth in the Indenture. The initial Depository for such Global Securities shall be The Depository Trust Company.

(j) The Notes shall be denominated in Dollars and the payment of the principal of and interest on the Notes shall be in Dollars.

(k) The Notes shall be defeasible as provided in Article IX of the Indenture.

(l) The Notes shall not be subject to any mandatory sinking fund.

(m) If a Change of Control Triggering Event occurs with respect to the Notes, unless the Company has exercised its right to redeem the Notes as described in Section 4.2 of the Indenture and clause (A)(g) of this Officers’ Certificate, Holders of Notes shall have the right to require the Company to make an offer to each Holder of Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth in the Notes. In the Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to the date of the consummation of any Change of Control, but after the public announcement of the transaction that constitutes or may constitute the Change of Control, the Company shall be required to mail a notice to the Holders of the Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the applicable notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the Notes and described in such notice. The notice shall, if mailed prior to the date of the consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the applicable Change of Control Payment Date. The Company must comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Notes, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Notes by virtue of such conflicts.

“Capital Stock” of a corporation means the capital stock of every class whether now or hereafter authorized, regardless of whether such capital stock shall be limited to a fixed sum or percentage with respect to the rights of the holders thereof to participate in dividends and in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of such corporation.

“Fitch” means Fitch Inc., and its successors.

“Investment Grade Rating” means a rating equal to or higher than BBB- (or the equivalent) by Fitch, Baa3 (or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company.

(ii) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

The paying agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Note, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases all Notes properly tendered and not withdrawn under its offer. In addition, the Company will not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a Default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

(o) Any reference to a merger, consolidation, amalgamation, distribution, assignment, sale, transfer, disposition or similar term, shall be deemed to apply to a division of or by a limited liability company, limited partnership or trust, or an allocation of assets of a limited liability company, limited partnership or trust (or the unwinding of such a division or allocation), as if it were a merger, consolidation, amalgamation, distribution, assignment, sale, transfer, disposition or similar term, as applicable, to, of or with a separate Person.

(i) within 12 months after the receipt of the proceeds of the sale or transfer, the Company or any Subsidiary apply an amount equal to the greater of the net proceeds of the sale or transfer or the fair value of such Property at the time of such sale or transfer to the prepayment or retirement (other than any mandatory prepayment or retirement) of Senior Funded Debt; or

(ii) the Company or such Subsidiary would be entitled, at the effective date of the sale or transfer, to incur debt secured by a Lien on such Property in an amount at least equal to the Attributable Debt in respect of the Sale and Leaseback Transaction, without equally and ratably securing the Notes pursuant to Section 5.8 of the Indenture.

The foregoing restriction in the paragraph above shall not apply to any Sale and Leaseback Transaction (i) for a term of not more than three years including renewals; or (ii) between the Company and a Subsidiary or between Subsidiaries, provided that the lessor is the Company or a wholly owned Subsidiary.

“Attributable Debt” in respect of a Sale and Leaseback Transaction means, at the time of determination, the present value discounted at the rate of interest implicit in the terms of the lease (as determined in good faith by the Company) of the obligations of the lessee under such lease for net rental payments during the remaining term of the lease (including any period for which such lease has been extended or may, at the Company’s option, be extended).

“Funded Debt” means debt which matures more than one year from the date of creation, or which is extendable or renewable at the sole option of the obligor so that it may become payable more than one year from such date or which is classified, in accordance with United States generally accepted accounting principles, as long-term debt on the consolidated balance sheet for the most recently ended fiscal quarter (or if incurred subsequent to the date of such balance sheet, would have been so classified) of the person for which the determination is being made. Funded Debt does not include (1) obligations created pursuant to leases, (2) any debt or portion thereof maturing by its terms within one year from the time of any computation of the amount of outstanding Funded Debt unless such debt shall be extendable or renewable at the sole option of the obligor in such manner that it may become payable more than one year from such time, or (3) any debt for which money in the amount necessary for the payment or redemption of such debt is deposited in trust either at or before the maturity date thereof.

“Senior Funded Debt” means all Funded Debt of the Company or its Subsidiaries (except Funded Debt, the payment of which is subordinated to the payment of the Notes).

(s) Section 7.1(e) of the Indenture is hereby amended by replacing the reference to “$35 million” set forth therein with a reference to “$75 million.”

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 “3.125% Senior Notes due 2024” of the Company (herein referred to as the “Notes”), initially issued in an aggregate principal amount of three hundred million dollars ($300,000,000). 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. If the Notes are redeemed before March 18, 2024 (one month prior to the maturity date of the Notes) (the “Par Call Date”), the redemption price will equal 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 to be redeemed that would have been due if the Notes matured on the Par Call Date (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, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption. If the Notes are redeemed on or after the Par Call Date, the redemption price for the Notes will equal 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption.

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 occurring prior to the Par Call Date 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.

(i) within 12 months after the receipt of the proceeds of the sale or transfer, the Company or any Subsidiary apply an amount equal to the greater of the net proceeds of the sale or transfer or the fair value of such Property at the time of such sale or transfer to the prepayment or retirement (other than any mandatory prepayment or retirement) of Senior Funded Debt; or

(ii) the Company or such Subsidiary would be entitled, at the effective date of the sale or transfer, to incur debt secured by a Lien on such Property in an amount at least equal to the Attributable Debt in respect of the Sale and Leaseback Transaction, without equally and ratably securing the Notes pursuant to Section 5.8 of the Indenture.

“Funded Debt” means debt which matures more than one year from the date of creation, or which is extendable or renewable at the sole option of the obligor so that it may become payable more than one year from such date or which is classified, in accordance with United States generally accepted accounting principles, as long-term debt on the consolidated balance sheet for the most recently ended fiscal quarter (or if incurred subsequent to the date of such balance sheet, would have been so classified) of the person for which the determination is being made. Funded Debt does not include (1) obligations created pursuant to leases, (2) any debt or portion thereof maturing by its terms within one year from the time of any computation of the amount of outstanding Funded Debt unless such debt shall be extendable or renewable at the sole option of the obligor in such manner that it may become payable more than one year from such time, or (3) any debt for which money in the amount necessary for the payment or redemption of such debt is deposited in trust either at or before the maturity date thereof.

“Senior Funded Debt” means all Funded Debt of the Company or its Subsidiaries (except Funded Debt, the payment of which is subordinated to the payment of the Notes).

Maturity Date: April 18, 2029

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 four hundred and fifty million dollars ($450,000,000) (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 18, 2019. 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 3 or the October 3 (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 Atlanta, Georgia, 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 18, 2019 (the “Officers’ Certificate”), establishing the terms of the Notes (the “Indenture”), between the Company and Regions Bank (as successor in interest to 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 “3.750% Senior Notes due 2029” of the Company (herein referred to as the “Notes”), initially issued in an aggregate principal amount of four hundred and fifty million dollars ($450,000,000). 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. If the Notes are redeemed before January 18, 2029 (three months prior to the maturity date of the Notes) (the “Par Call Date”), the redemption price will equal 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 to be redeemed that would have been due if the Notes matured on the Par Call Date (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 20 basis points, as determined in good faith by the Company, plus accrued and unpaid interest thereon, if any, to, but excluding the date of redemption. If the Notes are redeemed on or after the Par Call Date, the redemption price for the Notes will equal 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption.

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 occurring prior to the Par Call Date 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.

Maturity Date: April 18, 2029

Interest Rate: 3.750%

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 four hundred and fifty million dollars ($450,000,000) (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 18, 2019. 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 3 or the October 3 (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 Atlanta, Georgia, 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 18, 2019 (the “Officers’ Certificate”), establishing the terms of the Notes (the “Indenture”), between the Company and Regions Bank (as successor in interest to 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 “3.750% Senior Notes due 2029” of the Company (herein referred to as the “Notes”), initially issued in an aggregate principal amount of four hundred and fifty million dollars ($450,000,000). 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. If the Notes are redeemed before January 18, 2029 (three months prior to the maturity date of the Notes) (the “Par Call Date”), the redemption price will equal 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 to be redeemed that would have been due if the Notes matured on the Par Call Date (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 20 basis points, as determined in good faith by the Company, plus accrued and unpaid interest thereon, if any, to, but excluding the date of redemption. If the Notes are redeemed on or after the Par Call Date, the redemption price for the Notes will equal 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption.

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 occurring prior to the Par Call Date 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.

Re: AutoZone, Inc. 3.125% Senior Notes due 2024 and 3.750% Senior Notes due 2029

We have acted as counsel to AutoZone, Inc.

The Notes are to be issued pursuant to the provisions of the Indenture, dated as of August 8, 2003, by and between the Company and Regions Bank, successor in interest to The Bank of New York Mellon Trust Company, N.A., successor in interest to Bank One Trust Company, N.A., as trustee (the “Trustee”), as supplemented by separate officers’ certificates relating to the Notes, each dated as of April 18, 2019 (collectively, the “Indenture”), including the forms of global notes representing the Notes (the “Global Notes”).

In connection with this opinion, we have examined and relied upon such records, documents, certificates and other instruments as in our judgment are necessary or appropriate to form the basis for the opinions hereinafter set forth. In all such examinations, we have assumed the genuineness of signatures on original documents and the conformity to such original documents of all copies submitted to us as certified, conformed or photographic copies, and as to certificates of public officials, we have assumed the same to have been properly given and to be accurate. As to matters of fact material to this opinion, we have relied upon statements and representations of representatives of the Company and public officials.

We have assumed for purposes of this opinion that (a) each of the Company and the Trustee is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization; (b) each of the Company and the Trustee has the requisite power and authority to execute and deliver and to perform its obligations under each of the Indenture and the Notes; (c) each of the Company and the Trustee has duly authorized, executed and delivered each of the Indenture and the Notes (except that no such assumption is made with respect to execution and delivery thereof by the Company under the laws of the State of New York); (d) each of the Indenture and the Notes constitutes a legally valid and binding agreement of the Trustee, enforceable against it in accordance with its terms; and (e) the Trustee is in compliance, generally and with respect to acting as Trustee under the Indenture, with all applicable laws and regulations.

To the extent our opinion set forth below relates to the enforceability of the choice of New York law and choice of New York forum provisions of the Indenture and the Notes, our opinion is rendered in reliance upon N.Y. Gen. Oblig. Law §§5-1401, 5-1402 and N.Y. C.P.L.R. 327(b) and is subject to the qualification that such enforceability may be limited by public policy considerations of any jurisdiction, other than the courts of the State of New York, in which enforcement of such provisions, or of a judgment upon an agreement containing such provisions, is sought. We have also assumed that the Company has complied with all aspects of applicable laws of jurisdictions other than the State of New York in connection with the transactions contemplated by the Indenture. As to facts material to the opinion expressed herein, we have relied upon statements and representations of officers and other representatives of the Company, public officials and others.

Our opinion set forth herein is limited to the laws of the State of New York that, in our experience, are applicable to the Notes and, to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws (all of the foregoing being referred to as “Covered Law”). We do not express any opinion with respect to the law of any jurisdiction other than the Covered Law or as to the effect of any such non-covered law on the opinion herein stated or the securities or “blue sky” laws of any jurisdiction. The opinion expressed in this opinion letter is strictly limited to the matters stated in this opinion letter and no other opinions are to be implied.

The opinion rendered in the above paragraph is subject to the following exceptions, limitations and qualifications: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent transfer and fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance, injunctive relief and other equitable remedies), regardless of whether considered in a proceeding at law or in equity; (iii) the unenforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) the unenforceability of any provision requiring the payment of attorneys’ fees, where such payment is contrary to law or public policy. We express no opinion (i) concerning the enforceability of any waiver of rights or defenses with respect to stay, extension or usury laws, (ii) with respect to whether acceleration of the Notes may affect the collectibility of any portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon or (iii) as to the enforceability of any provision to the extent it requires any party to indemnify any other person against loss in obtaining the currency due following a court judgment rendered in another currency. The opinions rendered in the above paragraph do not include opinions with respect to compliance with laws relating to permissible rates of interest.

In rendering the opinion set forth above, we have assumed that the execution and delivery by the Company of the Indenture and the Notes and the performance by the Company of its obligations thereunder do not and will not violate, conflict with or constitute a default under any agreement or instrument to which the Company or its properties is subject. We hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement through a Current Report on Form 8-K. We also hereby consent to the reference to our firm under the caption “Legal Matters” in the Registration Statement and the Prospectus. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder. This opinion is expressed as of the date hereof unless otherwise expressly stated, and we disclaim any undertaking to advise you of any subsequent changes in the facts stated or assumed herein or of any subsequent changes in applicable law.
