PURSUANT TO SECTION 3.2 OF THE INDENTURE 

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 October 6, 2015 (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 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 2026” (the “Notes”). 
 (b) The Notes shall be issued at a price of 99.974% 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 $400,000,000. 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 21, 2026, 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 21, 2016, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, payable semiannually on April 21 and October 21 of each year (each an “Interest Payment Date”), commencing on October 21, 2016 until the principal
amount of the Notes has been paid or duly provided for. The April 6 and October 6 (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 New York, New York. 
 (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 January 21, 2026 (three months prior to the maturity date of the Notes), 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 

  
 1 








 
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 (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 25 basis points, as determined in good faith by
the Company. If the Notes are redeemed on or after January 21, 2026 (three months prior to the maturity date of the Notes), the redemption price will equal accrued and unpaid interest on the principal amount being redeemed to the redemption
date plus 100% of the principal amount of such Notes to be redeemed. 
 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 January 21, 2026 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.

 (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

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

liquidation, dissolution or winding up of such corporation. 
 “Change of Control” means the occurrence of any of
the following: (1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the

Company’s outstanding Voting Stock or the Voting Stock of such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Company’s Voting Stock outstanding

transaction; (4) the first day on which a majority of the members of the Board of Directors are not Continuing Directors; or (5) the adoption of a plan relating to the Company’s liquidation or dissolution. Notwithstanding the
foregoing, a transaction shall not be deemed to involve a Change of Control under clause (2) above if (i) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (ii)(A) the direct or indirect Holders of
the Voting Stock of such holding company immediately following that transaction are substantially the same as the Holders of the Company’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no
Person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

“Continuing Directors” means, as of any date of determination, any member of the Board of Directors who (A) was
a member of such Board of Directors on the date the Notes were issued or (B) was nominated for election, elected or appointed to such Board of Directors with the approval of a majority of the continuing directors who were members of such Board
of Directors at the time of such nomination, election or appointment (either by a specific vote or by approval of a proxy statement in which such member was named as a nominee for election as a director, without objection to such nomination). 

“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

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

(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) The Company shall not,
and shall not permit any Subsidiary to, enter into any arrangement with any Person providing for the leasing by the Company or any Subsidiary of any Property that has been or is to be sold or transferred by the Company or such Subsidiary to such

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

 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

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). 
 (p) Clause (xiii) of the definition of “Permitted Liens” in
Section 1.1 of the Indenture is hereby replaced and superseded in its entirety to read as follows: 
 (xiii) Liens existing on
April 21, 2016, or any extension, amendments, renewals, refinancings, replacements or other modifications thereto. 
 (q) Clause
(xviii) of the definition of “Permitted Liens” in the Indenture is hereby replaced and superseded in its entirety to read as follows: 

(xviii) other Liens on Property of the Company and its Subsidiaries securing debt having an aggregate principal amount (or deemed amount, in
the case of Attributable Debt) not to exceed, as of any date of incurrence of such secured debt pursuant to this clause and after giving effect to such incurrence and the application of the proceeds therefrom, the greater of (1) $500 million
and (2) 15% of the Company’s Consolidated Net Tangible Assets. 

  
 6 








 (r) 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.” 
 (s) The Notes shall be entitled to the benefit of
the covenants in Article V of the Indenture. 
 (t) 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. 

(u) There shall be no Events of Default other than those provided in Section 7.1 of the Indenture and the failure by the Company to comply
with the provisions of clauses A.(m) or (n) hereof. 
 (v) The Notes shall have additional terms and conditions as set forth in, and
shall be substantially in the form of, Annex A attached hereto, with such modifications thereto as may be approved by the authorized officer or officers executing the same. 

(w) The Trustee shall be the trustee for or on behalf of the Holders of the Notes. 

B. The undersigned hereby approve the sale of $400,000,000 aggregate principal amount of Notes by the Company to the Underwriters listed in
Schedule I to that certain Underwriting Agreement dated April 18, 2016 and in accordance with and pursuant to the terms thereof at a net purchase price to the Company of 99.324% of the principal amount thereof plus accrued interest, if any from
April 21, 2016, and with an initial price to the public of 99.974% of the principal amount thereof plus accrued interest, if any from April 21, 2016. 

The Indenture, as supplemented by this Officers’ Certificate, is in all respects ratified and confirmed, and this Officers’
Certificate shall be deemed part of the Indenture in the manner and to the extent herein and therein provided. 
 This Officers’
Certificate may be executed in one or more counterparts, including, without limitation, facsimile counterparts, each of which so executed shall be deemed to be an original, and shall together constitute one and the same Officers’ Certificate.

 THIS OFFICERS’ CERTIFICATE AND THE SECURITIES SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT

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 “3.125% Senior Notes due 2026” of the Company (herein referred to as the “Notes”), initially issued in an aggregate principal amount of four hundred million
dollars ($400,000,000). 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.

Officer’s Certificate 








 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 21, 2026 (three months prior to the maturity date of the Notes), 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 25 basis points, as determined in good faith by the Company. If the Notes are redeemed on or after January 21, 2026 (three months prior to the maturity date of the Notes), the redemption price
will equal accrued and unpaid interest on the principal amount being redeemed to the redemption date plus 100% of the principal amount of such Notes to be redeemed. 

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 January 21, 2026 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.

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.
