 SECTION 103.    Form of Documents Delivered to Trustee. 

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary
that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. 
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be
consolidated and form one instrument. 
 SECTION 104.    Acts of Holders. 

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or
taken by Holders (or Holders of any series) may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments, proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. 

(b) The fact and date of the execution by any person of any such instrument or writing may be proved by the affidavit of a witness of
such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the
authority of the person executing the same, may also be proved in any other manner which the Trustee deems sufficient; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this Section.

 (c) The ownership of Securities and the principal amount held by any Person and the date of holding the same shall be proved
by the Security Register. 
 (d) If the Company shall solicit from the Holders any request, demand, authorization, direction,
notice, consent, waiver or other Act, the Company may, at its option, by Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or
other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given 

  
 5 

 
before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the
requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of
such record date, provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provision of this Indenture not later than six months after the
record date. 
 (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any
Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by
the Trustee, the Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
 SECTION 105.    Notices, Etc., to Trustee and Company. 

Except as otherwise specifically provided herein, any request, demand, authorization, direction, notice, consent, waiver or Act of
Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: 
 (1)
the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office; or 

(2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to the attention of its Treasurer at [            ] or any other address subsequently
furnished in writing to the Trustee by the Company. 
 SECTION 106.    Notice to Holders; Waiver. 

Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders. Any notice mailed in the manner prescribed by this Indenture shall be conclusively presumed to have been duly given whether or not received by any particular Holder. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 In case by
reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient
notification for every purpose hereunder. 
 In the case of Global Securities, notices or communications to be given to Holders
shall be given to the Depository, in accordance with its applicable policies from time to time. 
 SECTION 107.    Conflict
with Trust Indenture Act. 
 If any provision hereof limits, qualifies or conflicts with another provision hereof which is
required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so
modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. 

SECTION 108.    Effect of Headings and Table of Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
 SECTION 109.    Successors and Assigns. 
 All covenants and
agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. All agreements of the Trustee, any additional trustee and any Paying Agents in this Indenture shall bind their respective successors and
assigns.

 SECTION 110.    Separability Clause. 

In case any provision of this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby, and a Holder shall have no claim therefor against any party hereto. 
 SECTION 111.    Benefits of Indenture. 
 Nothing in this
Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Security Registrar, or any Authenticating Agent and their respective successors hereunder and the Holders, any benefit
or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 112.    Governing Law. 

This Indenture and the Securities shall be governed and construed by and in accordance with the laws of the State of New York, as applied
to contracts made and performed within the State of New York without regard to principles of conflicts of laws. 
 SECTION
113.    Legal Holidays. 
 In any case where any Interest Payment Date, Redemption Date, the Stated Maturity
of any Security or any date upon which any Defaulted Interest is proposed to be paid shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest, if any,
or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date,
Redemption Date, at the Stated Maturity, or on the date for payment of Defaulted Interest, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or date for the payment of
Defaulted Interest, as the case may be, to the date of payment. 
 SECTION 114.    Indenture and Securities Solely Corporate
Obligations. 
 No recourse for the payment of the principal of (or premium, if any) or interest on any Security, or for any
claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture, or in any Security, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition
of, and as a consideration for, the execution of this Indenture and the issuance of the Securities. 
 SECTION
115.    Consent of Holders of Securities in a Foreign Currency or Euros. 
 Unless otherwise specified in a
certificate delivered pursuant to Section 301 of this Indenture with respect to a particular series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders of a specified percentage in aggregate principal
amount of Securities of all series or all series affected by a particular action at the time Outstanding and, at such time, there are Outstanding Securities of any series which are denominated in a coin, currency or currency unit other than Dollars,
then the principal amount of Securities of such series which shall be deemed to be Outstanding for the purpose of taking such action shall be that amount of Dollars that could be obtained for the stated Foreign Currency or Euro principal amount of
such Outstanding Securities at the Market Exchange Rate on the record date for the purpose of taking such action. If the appropriate Market Exchange Rate is not available for any reason with respect to such currency, the Trustee shall use, in its
sole discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York or, in the case of Euros, the rate of exchange as published in Journal, as of the most recent available date, or quotations or, in the case of
Euros, rates of exchange from one or more major banks in The City of New York or in the country of issue of the currency in question or, in the case of Euros, in Luxembourg, or such other quotations or, in the case of Euros, rates of exchange as the
Trustee, upon consultation with the Company, shall deem appropriate. All decisions and determinations of the Trustee regarding the Market Exchange Rate or any alternative determination provided for in the preceding paragraph shall be in its sole
discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Company and all Holders. 
 SECTION 116.    Payment Currency. 
 If the principal of and/or
interest on (or premium, if any, on) any Securities is payable in a Foreign Currency or Euros and such Foreign Currency or Euros is not available for payment due to the imposition of exchange controls or other circumstances beyond the control of the
Company, then the Company shall be entitled to satisfy its obligations to Holders under this Indenture by making such payment in Dollars on the basis of the Market Exchange Rate for such Foreign Currency or Euros on the latest date for which such

  
 7 

 
rate was established on or before the date on which payment is due. Any payment made under this Section in Dollars where the required payment is in a Foreign Currency or Euros shall not
constitute an Event of Default.

 All Securities of any one series shall be substantially identical
except as to denomination and the rate or rates of interest, if any, the date or dates from which interest shall accrue and maturity and except as may otherwise be provided in or pursuant to such Board Resolution and set forth in such Officers’
Certificate or in any such indenture supplemental hereto. 
 If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate
setting forth the terms of the series. 
 All Securities of any one series need not be issued at the same time, and may be
issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board Resolution, supplemental indenture or Officers’ Certificate referred to above. However, the authorized principal amount of any
series may not be increased to provide for issuances of additional Securities of such series, unless otherwise provided in such Board Resolution, supplemental indenture or Officers’ Certificate. 

SECTION 302.    Denominations. 
 The Securities of each series shall be issuable in registered form without coupons in such denominations as shall be specified as contemplated by Section 301. In the absence of any such provisions
with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof. 
 SECTION 303.    Execution, Authentication, Delivery and Dating. 
 The Securities shall be executed on behalf of the Company by any two of its Chairman of the Board, its President, any Vice President, its Treasurer or its Secretary, under its corporate seal reproduced
thereon. The signature of any of these officers on the Securities may be manual or facsimile. 
 Securities bearing the manual
or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of
such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver to the Trustee or an Authenticating Agent for authentication Securities of any series executed by the Company, together with a Company Order for the authentication and delivery of
such Securities, and the Trustee or such Authenticating Agent in accordance with the Company Order shall authenticate and deliver such Securities. If all the Securities of any series are not to be issued at one time, and if the Board Resolution,
Officers’ Certificate or supplemental indenture establishing such series shall so permit, such Company Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and the determination of the terms of particular
Securities of such series such as interest rate, maturity date, date of issuance and date from which interest shall accrue. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel stating, 
 (a) if the form of such Securities has been established by or
pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this Indenture; and 
 (b) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of
this Indenture. 
 If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an
Opinion of Counsel at the time of issuance of each Security, but such Opinion of Counsel, with appropriate modifications, may instead be delivered at or prior to the time of issuance of the first Security of such series. 

The Trustee or any Authenticating Agent shall have the right to authenticate and deliver any of such Securities if it, being advised by
counsel, determines that such action may not lawfully be taken, or if it, its board of directors, trustees, executive committee, or a trust committee of directors or trustees and/or vice presidents shall determine in good faith that such action
would expose it to personal liability to existing Holders or if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee. 
 Each Security shall be dated the date of its authentication. 

  
 10 

 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature, and such certificate upon any Security shall
be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 
 SECTION 304.    Temporary Securities. 
 Pending the
preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee or an Authenticating Agent shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their execution of such Securities. 
 Until so exchanged the
temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 
 SECTION 305.    Registration, Registration of Transfer and Exchange. 
 With respect to each series of Securities, the Company shall cause to be kept at one of the offices or agencies maintained pursuant to Section 1002 a register (the register maintained in such office
and in any other office or agency established by the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for the registration of Securities of that series and of transfers of Securities of that series. Pursuant to Section 301, the Company shall appoint, with respect to Securities of each series, a “Security
Registrar” for the purpose of registering such Securities and transfers and exchanges of such Securities as herein provided. In the event the Trustee shall not be Security Registrar, it shall have the right to examine the Security Register at
all reasonable times. 
 Upon surrender for registration of transfer of any Security of any series at the designated office or
agency in a Place of Payment for that series, the Company shall execute, and the Trustee or an Authenticating Agent shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like tenor, aggregate principal amount and Stated Maturity. 
 At the option of
the Holder, Securities of any series (except Global Securities) may be exchanged for other Securities of the same series, of any authorized denominations and of a like tenor, aggregate principal amount and Stated Maturity, upon surrender of the
Securities to be exchanged at such office or agency and upon payment, if the Company shall so require, of the charges hereinafter provided. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee or an
Authenticating Agent shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Security presented or
surrendered for registration of transfer or exchange shall (if so required by the Company or the Trustee or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar (and, if so required by the Trustee, to the Trustee) duly executed, by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may
be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. 

The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period
beginning at the opening of business 15 days before the day of selection for redemption of Securities of that series selected for redemption under Section 1103 and ending at the close of business on the day of the mailing of notice of
redemption, or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

SECTION 306.    Mutilated, Destroyed, Lost and Stolen Securities. 

If there shall be delivered to the Company and the Trustee (i) a mutilated Security or evidence to their satisfaction of the
destruction, loss or theft of any Security and (ii) such security or indemnity bond as may be determined in the reasonable judgment of the Company or the Trustee, as the case may be, to protect the Company, the Trustee and any agent of either
of them from any loss which any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request
the Trustee or an Authenticating Agent 

  
 11 

 
shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security, a new Security of the same series and of like tenor, principal amount and
Stated Maturity and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen
Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series
issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities. 
 SECTION 307.    Payment of Interest; Interest Rights Preserved; Optional Interest Reset. 

(a) Except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, interest
on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest. 
 Any interest on any Security of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed
payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less
than l0 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities
of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 

(2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause,
such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 

(b) The provisions of this Section 307(b) may be made applicable to any series of Securities pursuant to Section 301 (with such
modifications, additional or substitutions as may be specified pursuant to Section 301). The interest rate on any Security of such series may be reset by the Company on the date or dates specified on the face of such Security (each an
“Optional Reset Date”). The Company may exercise such option with respect to a Security by notifying the Trustee of all of the relevant information relating to such exercise at least 50 but not more than 60 days prior to an Optional Reset
Date, the Trustee shall transmit, in the manner provided for in Section 106, to the Holder of any such Security a notice (the “Reset Notice”) indicating whether the Company has elected to reset the interest rate, and if so
(i) such new interest rate and (ii) the provisions, if any, for redemption during the period from such 

  
 12 

 
Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the Stated Maturity Date of such Security (each such period a “Subsequent Interest
Period”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period. 

Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the Company may, at its option, revoke the
interest rate provided for in the Reset Notice and establish a higher interest rate for the Subsequent Interest Period by causing the Trustee to transmit, in the manner provided for in Section 106, notice of such higher interest rate to the
Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest rate is reset on an Optional Reset Date will bear such higher interest rate. 

The Holder of any such Security will have the option to elect repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment
at the option of Holders, as such apply to such Security, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the holder has tendered
any Security for repayment pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset Date. 

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration
of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
 SECTION 308.    Persons Deemed Owners. 
 Prior to due
presentment of a Security for registration of transfer, the Company, the Trustee, any Paying Agent, any Authenticating Agent and any other agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the
owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 307) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue,
and neither the Company, the Trustee, any Paying Agent, any Authenticating Agent nor any other agent of the Company or the Trustee shall be affected by notice to the contrary. 
 None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial
ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the
Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any Depositary, as a Holder, with respect to such Global Security or impair, as between such
Depositary and owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security. 

SECTION 309.    Cancellation. 
 All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities shall be destroyed by the Trustee and the Trustee shall deliver a certificate of such destruction to the Company, unless the Company by Company Order shall direct that such cancelled Securities be returned to it.

 SECTION 310.    Computation of Interest. 
 Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day
months. 
 SECTION 311.    Global Securities. 
 If the Company shall establish pursuant to Section 301 that the Securities of a series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall
execute and the Trustee shall, in accordance with Section 303 and the Company Order with respect to such series, authenticate and deliver one or more Global Securities in temporary or permanent form that (i) shall represent and shall be
denominated in an amount equal to the aggregate principal amount of the outstanding Securities of such series to be represented by one or more Global Securities, (ii) shall be registered in the name of the Depositary for such Global Security or
Securities or the nominee of such depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant to such 

  
 13 

 
Depositary’s instruction, and (iv) shall bear a legend substantially to the following effect: “This Security is a Global Security within the meaning of the Indenture hereinafter
referred to, and is registered in the name of the Depository or a nominee of the Depository. This Security is exchangeable for Securities registered in the name of a Person other than the Depository or its nominee only in the limited circumstances
described in the Indenture, and may be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to
a successor Depositary or a nominee of such successor Depositary.” The Trustee shall deal with the Depositary and its participants as representatives of the Beneficial Owners of the Global Securities for purposes of exercising the rights of the
Holders hereunder and the rights of the Beneficial Owners of the Global Securities shall be limited to those established by law and agreements between such Beneficial Owners and the Depositary and its participants. Beneficial Owners shall not be
entitled to certificates for Global Securities as to which they are the Beneficial Owners. Requests and directions from, and votes of, such representatives shall not be deemed to be inconsistent if they are made with respect to different Beneficial
Owners. 
 Notwithstanding any other provision of this Section or Section 305, unless and until it is exchanged in whole or
in part for Securities in definitive form, a Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary, by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor depositary. The Beneficial Owner’s ownership of Securities
shall be recorded on the records of a participant of the Depositary that maintains such Beneficial Owner’s account for such purpose and the participant’s record ownership of such Securities shall be recorded on the records of the
Depositary. 
 If at any time the Depositary for the Securities of a series notifies the Company that it is unwilling or unable
to continue as Depositary for the Securities of such series or if at any time the Depositary for Securities of a series ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, or other applicable statute or
regulation, the Company shall appoint a successor Depositary with respect to the Securities of such series. If a successor Depositary for the Securities of such series is not appointed by the Company within 90 days after the Company receives written
notice or becomes aware of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such
series, with like tenor and terms, in definitive form in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities. 

The Company may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more
Global Securities shall no longer be represented by such Global Security or Securities. In such event, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such
series, will authenticate and deliver, Securities of such series, with like tenor and terms, in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in
exchange for such Global Security or Securities. 
 If specified by the Company pursuant to Section 301 with respect to
Securities of a series, the Depositary for such series of Securities may surrender a Global Security for such series of Securities in exchange in whole or in part for Securities of such series in definitive form on such terms as are acceptable to
the Company and such Depositary. Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without charge, 
 (i) to each Person specified by the Depositary a new Security or Securities of the same series of like tenor and terms, of any authorized denomination as requested by such Person in aggregate principal
amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and 
 (ii) to the Depositary
a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Securities delivered to Holders thereof. 

Upon the exchange of a Global Security for Securities in definitive form, such Global Security shall be cancelled by the Trustee.
Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the persons in whose names such Securities are so registered. 
 The Depository, as a Holder, may appoint agents and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder
is entitled to give or take under this Indenture. 
 Notwithstanding the other provisions of this Indenture, unless otherwise
specified as contemplated by Section 301, payment of the principal of, and interest and premium, if any, on, any Global Security shall be made to the Depository or its nominee in its capacity as the Holder thereof. Further, the Company, the
Trustee and any Authentication Agent shall treat a Person as the Holder of such principal amount of outstanding Securities of any series represented by a Global Security as shall be specified in a written statement of the Depository (which may be in
the form of a participants’ list for such series) with respect to such Global Security, for 

  
 14 

 
purposes of obtaining any consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture, provided, that until the Trustee is so provided with a
written statement, it may treat the Depository or any other Person in whose name a Global Security is registered as the owner of such Global Security for all purposes, and none of the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary. 
 SECTION 312.    Optional Extension of Maturity. 

The provisions of this Section may be made applicable to any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to Section 301). The Stated Maturity of any Security of such series may be extended at the option of the Company for the period or periods specified on the face of such Security (each an
“Extension Period”) up to but not beyond the date (the “Final Maturity”) set forth on the face of such Security. The Company may exercise such option with respect to any Security by notifying the Trustee of such exercise at least
50 but not more than 60 days prior to the Stated Maturity of such Security in effect prior to the exercise of such (the “Original Stated Maturity”). If the Company exercises such option, the Trustee shall transmit, in the manner provided
for in Section 106, to the Holder of such Security not later than 40 days prior to the Original Stated Maturity a notice (the “Extension Notice”) indicating (i) the election of the Company to extend the Maturity, (ii) the
new Stated Maturity Date, (iii) the interest rate applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustee’s transmittal of the Extension Notice, the Stated
Maturity Date of such Security shall be extended automatically and, except as modified by the Extension Notice and as described in the next paragraph, such Security will have the same terms as prior to the transmittal of such Notice. 

Notwithstanding the foregoing, not later than 20 days before the Original Stated Maturity of such Security, the Company may, at its
option, revoke the interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to transmit, in the manner provided for in Section 106, notice of such higher interest
rate to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate. 

If the Company extends the Maturity of any Security, the Holder will have the option to elect repayment of such Security by the Company
on the Original Stated Maturity at a price equal to the outstanding principal amount thereof, plus interest accrued to such date. In order to obtain repayment on the Original Stated Maturity once the Company has extended the Maturity thereof, the
Holder of an Outstanding Security must follow the procedures set forth in Article Thirteen for repayment at the option of Holders, as such applies to the Securities of such series, except that the period for delivery or notification to the Trustee
shall be at least 25 but not more than 35 days prior to the Original Stated Maturity and except that, if the Holder has tendered any Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such
tender for repayment until the close of business on the tenth day before the Original Stated Maturity unless the Trustee has previously delivered repayment of such Security to such Holder. 
 SECTION 313.    CUSIP and ISIN Numbers. 
 The Company in
issuing the Securities may use one or more “CUSIP” and “ISIN” numbers (if then generally in use), and, if the Company does so, the Trustee shall use the CUSIP number(s) and ISIN numbers in notices of redemption or exchange as a
convenience to Holders, provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP and ISIN number(s) printed in the notice or on the Securities, and that reliance may be placed only on the
other identification numbers printed on the Securities, and that any such redemption or exchange shall not be affected by any defect in or omission of any such numbers. 
 ARTICLE FOUR 
 SATISFACTION AND DISCHARGE 

SECTION 401.    Satisfaction and Discharge of Securities of any Series. 

The Company shall be deemed to have satisfied and discharged the entire indebtedness on all the Securities of any particular series and
the Trustee, upon Company request and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of such indebtedness, when 
 (1) either: 
 (A) all Securities of such series theretofore authenticated and
delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (ii) Securities for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in the last paragraph of Section 1003) have been delivered to the Trustee for cancellation; or 

  
 15 

 (B) with respect to all Outstanding Securities of such series described in (A) above
not theretofore delivered to the Trustee for cancellation, 
 (i) The Company has deposited or caused to be deposited with the
Trustee as trust funds in trust an amount sufficient to pay and discharge the entire indebtedness on all such Outstanding Securities of such series for principal (and premium, if any) and interest to the Stated Maturity or any Redemption Date as
contemplated by Section 403, as the case may be; or 
 (ii) The Company has deposited or caused to be deposited with the
Trustee as obligations in trust such amount of direct obligations of, or obligations the principal of and interest on which are fully guaranteed by, the United States of America (other than obligations subject to prepayment, redemption or call prior
to their stated maturity) as will, together with the predetermined and certain income to accrue thereon (without consideration of any reinvestment thereof), be sufficient to pay and discharge when due the entire indebtedness on all such Outstanding
Securities of such series for principal (and premium, if any) and interest to the Stated Maturity or any Redemption Date as contemplated by Section 403, as the case may be; 

(2) the Company has paid or caused to be paid all other sums payable with respect to the Securities of such series; 

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of the entire indebtedness on all Securities of such series have been complied with; and 
 (4) if the entire indebtedness on the Outstanding Securities of such series is to be satisfied and discharged pursuant to Section 401(l)(B) above, then (i) the Company shall have specified the
applicability (as provided in Section 301) of this Section 401(4) to the Securities of such series, (ii) the Company shall have given, not later than the date of such deposit, notice of such deposit to the Holders of Securities of
such series and (iii) the Trustee shall have received an Opinion of Counsel (which Counsel shall be recognized tax counsel) stating that, (x) the Company has received from the Internal Revenue Service a ruling or (y) since the date of
this Indenture, there has been a change in the applicable federal income tax law, including by means of a Revenue Ruling published by the Internal Revenue Service, in either case to the effect that, and based thereon such Opinion of Counsel will
confirm that the deposit of funds or obligations and the satisfaction and discharge of indebtedness on the Securities of such series pursuant to this Section will not result in recognition by the Holders of income, gain or loss for federal income
tax purposes (other than income, gain or loss which would have been recognized in like amount and at a like time absent such deposit, satisfaction and discharge), provided that the Company will be discharged from the requirements of Article Eight if
(i) it has satisfied all of the requirements for satisfaction and discharge of the indebtedness on the Outstanding Securities pursuant to Section 401(1)(B) except for the delivery of the Opinion of Counsel described above, and
(ii) the Trustee shall have received an Opinion of Counsel stating that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of the deposit of such funds or obligations and will be subject to federal
tax in the same amounts, in the same manner and at the same times as would have been the case if such deposit of funds or obligations had not occurred. 
 Upon the satisfaction of the conditions set forth in this Section with respect to all the Securities of any series, the terms and conditions of such series, including the terms and conditions with respect
thereto set forth in this Indenture, shall no longer be binding upon, or applicable to, the Company, and the Holders of the Securities of such series shall look for payment only to the funds or obligations deposited with the Trustee pursuant to
Section 401(l)(B); provided, however, that, in no event shall the Company be discharged (a) from any payment obligations in respect of Securities of such series which are deemed not to be Outstanding under clause (iii) of the
definition thereof if such obligations continue to be valid obligations of the Company under applicable law, (b) from any obligations under Section 607 or the last paragraph of Section 1003, and (c) from any obligations under
Section 305 and 306 (except that Securities of such series issued upon registration of transfer or exchange or in lieu of mutilated, lost, destroyed or stolen Securities shall not be obligations of the Company), and Section 701.

 SECTION 402.    Satisfaction and Discharge of Indenture. 

Upon compliance by the Company with the provisions of Section 401 as to the satisfaction and discharge of each series of Securities
issued hereunder, this Indenture shall cease to be of any further effect (except as otherwise provided herein). Upon Company Request (and at the expense of the Company), the Trustee shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture. In the event there are two or more Trustees hereunder, then the effectiveness of any such instrument shall be conditioned upon receipt of such instruments from all Trustees hereunder. 

Notwithstanding the satisfaction and discharge of this Indenture, any obligations of the Company under Sections 305, 306, 607 and 701 and
the last paragraph of Section 1003, and of the Trustee under Sections 403 and 613 and the last two paragraphs of Section 1003, shall survive. 

  
 16 

 SECTION 403.    Application of Trust Money. 

Subject to the provisions of the last two paragraphs of Section 1003, all money and obligations deposited with the Trustee pursuant
to Section 401 shall be held irrevocably in trust and shall be made under the terms of an escrow trust agreement in form and substance satisfactory to the Trustee. Such money and obligations shall be applied by the Trustee, in accordance with
the provisions of the Securities, this Indenture and such escrow trust agreement, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal of (and premium, if any) and interest, if any, on the Securities for the payment of which such money and obligations have been deposited with the Trustee (but such money need not be segregated from other funds
except to the extent required by law). If Securities of any series are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any mandatory sinking fund requirement, the Company
shall make such arrangements as are satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. 
 ARTICLE FIVE

 SECTION 501.    Events of Default. 
 “Event of
Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(C) consents to the appointment of a Custodian of it or for all or substantially all of its property, or

liquidator or similar official under any Bankruptcy Law. 
 (7) any other Event of Default provided with respect to the

 17 

 SECTION 502.    Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such
declaration such principal amount (or specified portion) shall become immediately due and payable. 
 Upon payment of such
amount, all obligations of the Company in respect of the payment of principal of the Securities of such series shall terminate. 

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if: 
 (1) the Company has paid or deposited with the
Trustee a sum sufficient to pay 
 (A) all overdue interest, if any, on all Securities of that series, 

(B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of
acceleration and interest thereon at the rate or rates prescribed therefor in such Securities, 
 (C) to the extent that payment
of such interest is lawful, interest upon overdue interest at the rate or rates, if any, prescribed therefor in such Securities, and 
 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that
series which have become due solely by such declaration of acceleration, have been cured, or waived as provided in Section 513. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 

SECTION 503.    Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if: 
 (1) default is made in the payment of any interest on any Security of any series when such interest becomes due and payable and such default continues for a period of 30 days, or 

(2) default is made in the payment of the principal of (or premium, if any, on) any Security of any series at the Maturity thereof, the
Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of Securities of such series, the whole amount then due and payable on Securities of such series for principal (and premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates, if any, prescribed therefor in such Securities; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of
Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

 SECTION 504.    Trustee May File Proofs of Claim. 

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be
due and payable as therein expressed or by declaration of acceleration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered,
by intervention in such proceeding or otherwise, 
 (i) to file and prove a claim for the whole amount of principal (or with
respect to Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such Securities), and premium, if any and interest owing and unpaid in respect of the Securities and to file such other papers or
documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in
such judicial proceeding, and 
 (ii) to collect and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 607. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment
or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 505.    Trustee May Enforce Claims Without Possession of Securities. 
 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
 SECTION 506.    Application of Money Collected. 
 Any money
collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon
presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee under Section 607; 

SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest, if any, on the Securities
in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, if any,
respectively; and 
 THIRD: The balance, if any, to the Company, its successor or assigns or to whoever may be lawfully entitled
to receive the same or as a court of competent jurisdiction may direct. 
 SECTION 507.    Limitation on Suits. 

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (1) An Event of
Default shall have occurred and be continuing with respect to the Securities of that series and such Holder shall have previously given written notice thereof to the Trustee; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of
Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee reasonable indemnity
against the costs, expenses and liabilities to be incurred in compliance with such request; 

  
 19 

 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity
has failed to institute any such proceeding; and 
 (5) no direction inconsistent with such written request has been given to
the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being
understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder or to obtain or
to seek to obtain priority or preference over any other Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders of Securities of such series. 

SECTION 508.    Unconditional Right of Holders to Receive Principal, Premium and Interest. 

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 307) interest, if any, on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 SECTION 509.    Restoration of Rights and Remedies. 
 If the
Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted. 
 SECTION 510.    Rights and Remedies
Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 511.    Delay or
Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 SECTION
512.    Control by Holders. 
 The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series,
provided that: 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture; 

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; 

(3) such direction is not unduly prejudicial to the rights of other Holders; and 

(4) such direction would not involve the Trustee in personal liability. 
 SECTION 513.    Waiver of Past Defaults. 
 The Holders of not
less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a
default 
 (1) in the payment of the principal of (or premium, if any) or interest, if any (subject to the provisions of
Section 502), on any Security of such series, or 

  
 20 

 (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified
or amended without the consent of the Holder of each Outstanding Security of such series 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 the Securities of such series under this Indenture; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon. 
 SECTION 514.    Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees at trial and on appeal, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder,
or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date). 
 ARTICLE SIX 
 THE TRUSTEE 
 SECTION 601.    Certain Duties and Responsibilities. 
 (a)
Except during the continuance of an Event of Default, 
 (1) the Trustee undertakes to perform such duties and only such duties
as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificate or opinion which by any provision hereof is specifically required to be furnished to the Trustee, the Trustee shall be under a
duty to examine the same to determine whether or not it conforms to the requirements of this Indenture. 
 (b) In case an Event
of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs. 
 (c) No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 

(1) this Subsection shall not be construed to limit the effect of Subsection (a) of this Section; 

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that
the Trustee was negligent in ascertaining the pertinent facts; 
 (3) the Trustee shall not be liable with respect to any action
taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities of any series, as provided in Section 512, relating to the time, method
and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series; and 

(4) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it. 
 (d) Whether or not herein expressly so provided, every provision of this Indenture relating to the
conduct of or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 

  
 21 

 SECTION 602.    Notice of Defaults. 

Within 90 days after the occurrence of any default hereunder with respect to the Securities of any series, the Trustee shall transmit by
mail to all Holders of Securities of such series, as their names and addresses appear in the Security Register, notice of such default hereunder actually known to a Responsible Officer of the Trustee, unless such default shall have been cured or
waived; provided, however, that except in the case of a default in the payment of the principal of (or premium, if any) or interest, if any, on any Security of such series, in the payment of any sinking fund installment with respect to Securities of
such series or in the payment of the Redemption Price of any Securities as to which notice of redemption has been given, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a
trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of Securities of such series; and provided, further, that in the case of any default
of the character specified in Section 501(4) with respect to Securities of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default”
means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series. 

SECTION 603.    Certain Rights of Trustee. 
 Subject to the provisions of Section 601: 
 (a) the Trustee may rely and
shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or
document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (b) any request or
direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 

(c) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 

(d) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
 (e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless
such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit; 
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney, including any Authenticating Agent, appointed with due care by it
hereunder; 
 (h) the Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be
authorized or within the discretion or rights or powers conferred upon it by this Indenture; and 
 (i) the Trustee shall not be
charged with knowledge of any Event of Default with respect to the Securities of any series for which it is acting as Trustee unless either (1) a Responsible Officer of the Trustee assigned to the Corporate Trust Office of the Trustee (or any
successor division or department of the Trustee) shall have actual knowledge of the Event of Default or (2) written notice of such Event of Default shall have been given to the Trustee by the Company, any other obligor on such Securities or by
any Holder of such Securities. 
 SECTION 604.    Not Responsible for Recitals or Issuance of Securities. 

The recitals contained herein and in the Securities, except certificates of authentication, shall be taken as the statements of the
Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof. 

  
 22 

 SECTION 605.    May Hold Securities. 

The Trustee, any Authenticating Agent, any Paying Agent, the Security Registrar or any other agent of the Company or the Trustee, in
their individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 612, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying
Agent, Security Registrar or such other agent. 
 SECTION 606.    Money Held in Trust. 

Money held by the Trustee or any Paying Agent in trust hereunder need not be segregated from other funds except to the extent required by
law. Neither the Trustee nor any paying Agent shall be subject to any liability for interest on any money received by it hereunder except as otherwise agreed with the Company. 
 SECTION 607.    Compensation and Reimbursement. 
 The Company
agrees: 
 (1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which
compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as
may be attributable to its negligence or bad faith; and 
 (3) to indemnify the Trustee and its agents for, and to hold them
harmless against, any loss, liability or expense incurred without negligence or bad faith on their part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of
defending themselves against any claim or liability in connection with the exercise or performance of any of their powers or duties hereunder. 
 As security for the performance of the obligations of the Company under this Section, the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the payment of principal (or premium, if any) or interest, if any, on Securities. 
 The
provisions of this Section shall survive the resignation or removal of the Trustee or the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of an Event of Default specified in Section 501(5) or (6) the
expenses are intended to constitute expenses of administration under any Bankruptcy Law. 
 SECTION 608.    Corporate
Trustee Required; Eligibility; Conflicting Interests. 
 This Indenture shall always have a Trustee who satisfies the
requirements of Trust Indenture Act Sections 310(a)(1), (2) and (5) in every respect. The Trustee (or in the case of a Trustee that is a Person included in a bank holding company system, the related bank holding company) shall have a
combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act Section 310(b), including the provision in Section 310(b)(1). In
addition, if the Trustee is a Person included in a bank holding company system, the Trustee, independently of such bank holding company, shall meet the capital requirements of Trust Indenture Act Section 310(a)(2). If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Article. 
 SECTION 609.    Resignation and Removal; Appointment of Successor. 
 (a) No resignation or removal of the Trustee and no appointment of a successor Trustee or Trustees pursuant to this Article shall become effective until the acceptance of appointment by the successor
Trustee or Trustees in accordance with the applicable requirements of Section 610. 
 (b) The Trustee may resign at any
time with respect to the Securities of one or more series by notifying the Company in writing at least 90 days in advance of such resignation. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been
delivered to the Trustee within 60 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

 (c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority
in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 

  
 23 

 (d) If at any time the Trustee shall fail to comply with Section 608 after written
request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, the Company by a Board Resolution may remove the Trustee with respect to the Securities of such series or, subject to
Section 514, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee with respect to the Securities of such series and the appointment of a successor Trustee. 
 (e) If at any time:

 (1) the Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by
the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall
become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, 
 then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, any holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
 (f) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 610. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of
such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 610, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company with respect to such series. If no successor Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders of the Securities of such series and accepted appointment in the manner required by Section 610, any Holder who has been a bona fide holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

(g) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and
each appointment of a successor Trustee with respect to the Securities of any series by mailing written notice of such event by first-class mail, postage prepaid, to all Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
 SECTION 610.    Acceptance of Appointment by Successor. 
 (a)
In case of the appointment hereunder of a successor Trustee with respect to all series of Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of
the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges due pursuant to Section 607, execute and deliver an instrument transferring to such successor Trustee
all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder subject to the lien provided in Section 607.

 (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all)
series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and
which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all series of Securities, shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities or that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the 

  
 24 

 
administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or these series to which the appointment of such successor Trustee relates. 

(c) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. 
 (d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. 

SECTION 611.    Merger, Conversion, Consolidation or Succession to Business. 

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from
any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities. 
 SECTION 612.    Preferential Collection of Claims Against Company. 

The Trustee shall comply with Trust Indenture Act Section 311(a), excluding any creditor relationship listed in Trust Indenture Act
Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated therein. 
 SECTION 613.    Appointment of Authenticating Agent. 
 At any
time when any of the Securities remain Outstanding the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate and deliver
Securities of such series with respect to which it has been so designated, and Securities so authenticated and delivered shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by
the Trustee hereunder. 
 Wherever reference is made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the
Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a bank or trust company or corporation organized and doing business and in good standing under the laws of the United States,
any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $100,000,000 and subject to supervision or examination by Federal, State or District of
Columbia authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and
surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the

case at any time such Authenticating Agent shall cease to be eligible in

 (1) to evidence the succession of another corporation to
the Company and the assumption by any such successor of the covenants of the Company herein and in the Securities; or 
 (2) to
add to the covenants of the Company for the benefit of the Holders of all or any series of Securities (and if such covenants are to be for the benefit of less than all series of Securities, stating that such covenants are expressly being included
solely for the benefit of such series) or to surrender any right or power herein conferred upon the Company; provided, however, that in respect of any such additional covenant, such supplemental indenture may provide for a particular period of grace
after default in the 

  
 27 

 
performance of such covenant (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such default or may limit the
remedies available to the Trustee upon such default; or 
 (3) to add any additional Events of Default; or 

(4) to add to or change or eliminate any of the provisions of this Indenture to extent as shall be necessary to permit or facilitate the
issuance of Securities in bearer form, registrable or not registrable as to principal, and with or without interest coupons; or 

(5) to change or eliminate any of the provisions of this Indenture, provided that any such change or elimination shall become effective
only when there is no Security Outstanding of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision; or 
 (6) to secure the Securities; or 
 (7) to establish the form or terms of
Securities of any series as permitted by Sections 201 and 301; or 
 (8) to evidence and provide for the acceptance of
appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, pursuant to the requirements of Section 610(b); or 
 (9) to cure any ambiguity, to
correct or supplement any provision herein which may be inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Indenture, provided such action shall not adversely affect
the interests of the Holders of Securities of any series in any material respect. 
 SECTION 902.    Supplemental Indentures
with Consent of Holders. 
 With the consent of the Holders of not less than a majority in principal amount of the Outstanding
Securities of each series (each such series voting as a separate class) affected by such supplemental indenture, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of
Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby, 

(1) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the
principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or modify the manner of determination of the rate of interest thereon so as to affect adversely the interest of such Holder or reduce the
amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502, or change any Place of Payment where, or the coin or currency in
which, any Security or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption
Date), or 
 (2) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose
Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this
Indenture, or 
 (3) modify any of the provisions of this Section, Section 513 or Section 1006, except to increase any
such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to
require the consent of any Holder with respect to changes in the references to the “Trustee” and concomitant changes in this Section and Section 1006, or the deletion of this proviso, in accordance with the requirements of Sections
610(b) and 901(8). 
 A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture
which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not
to affect the rights under this Indenture of the Holders of Securities of any other series. 
 The Trustee may in its discretion
determine whether or not any Securities would be affected by any supplemental indenture and any such determination shall he conclusive upon the Holders of all Securities of any series. The Trustee shall not be liable for any such determination made
in good faith. 
 It shall not be necessary for any Act of Holders under this Section to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

or permitted by this Indenture and that such supplemental indenture, when executed and delivered by the Company, will constitute a valid and binding obligation of the Company in accordance with its terms. The Trustee may, but shall not be obligated

SECTION 1002.    Maintenance of Office or Agency. 
 The Company will cause to be maintained in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location, of such office or agency. With respect to the Securities of any series such office or agency and each place of Payment shall be as specified as contemplated in

 The Company may also from time to time designate one or more other offices or agencies (in or outside the Borough of
Manhattan, City of New York, New York) where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such office or agency. 

  
 29 

 SECTION 1003.    Money for Securities Payments to Be Held in Trust. 

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due
date of the principal of (and premium, if any) or interest, if any, on any of the Securities of that series, segregate and hold in trust for the benefit of the persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or
interest, if any, so becoming due until such sums shall be paid to such persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest, if any, on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest, if any, so becoming due, such sum to be held in trust for
the benefit of the persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 

The Company will cause each Paying Agent other than the Trustee for any series of Securities to execute and deliver to the Trustee an
instrument in which such paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 
 (1) hold all sums held by it as agent for the payment of the principal of (and premium, if any) or interest, if any, on Securities of that series in trust for the benefit of the Persons entitled thereto
until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
 (2) give the Trustee written
notice within three Business Days of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest, if any, on the Securities of that series; and

 (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the
Trustee all sums so held in trust by such Paying Agent. 
 The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any paying Agent to the Trustee, such paying agent shall be released from all further liability with respect to such money. Upon the
satisfaction and discharge of the indebtedness in respect of all Outstanding Securities of any series all sums then held by any Paying Agent (other than the Trustee) in respect thereof shall, upon demand of the Company, be repaid to it or paid to
the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such money. 
 The
Trustee and any Paying Agent shall promptly pay to the Company upon Company Request any money or securities held by them at any time in excess of amounts necessary to satisfy amounts payable to the Holders, the Trustee and the Paying Agent.

 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the
principal of (and premium, if any) or interest, if any, on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest, if any, has become due and payable shall, unless otherwise required
by mandatory provisions of applicable escheat or abandoned or unclaimed property law, be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall, unless
otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the
Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in each Place of Payment with respect to Securities of such series, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will, unless otherwise required by mandatory provisions of
applicable escheat or abandoned or unclaimed property law, be repaid to the Company.

full force and effect its corporate existence.

Company is not in default in the fulfillment of any of its obligations under this Indenture, or specifying each such default known to him and the nature and status thereof and (b) no event has occurred and is continuing which is or after notice
or lapse of time or both would become an Event of Default, or, if such an event has occurred and is continuing, specifying each such event known to him and the nature and status thereof. 
 SECTION 1006.    Waiver of Certain Covenants. 
 The Company
may omit in any particular instance to comply with any covenant or condition set forth in Sections 1002 to 1005, each inclusive, or a supplemental indenture with respect to the Securities of any series if before the time for such compliance the
Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such
waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee with respect to any such covenant or
condition shall remain in full force and effect. 
 ARTICLE ELEVEN 

REDEMPTION OF SECURITIES 

SECTION 1101.    Applicability of Article. 
 Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for
Securities of any series) in accordance with this Article. 
 SECTION 1102.    Election to Redeem; Notice to Trustee.

 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at
the election of the Company of less than all the Securities of any series, the Company shall, at least 45 days (unless a shorter notice shall be satisfactory to the Trustee) prior to the Redemption Date fixed by the Company (unless a shorter notice,
but not less than 30 days, shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. Any such
notice may be canceled at any time prior to notice of such redemption being mailed to any Holder, and shall thereby be void and of no effect. 

SECTION 1103.    Selection by Trustee of Securities to be Redeemed. 

If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected by the
Trustee not more than 45 days prior to the Redemption Date, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized
denomination for Securities of that series. In any case where Securities of such series are registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Security
of such series. If the Securities of any series to be redeemed consist of Securities having different Stated Maturities or different rates of interest (or methods of computing interest), then the Company may, by written notice to the Trustee, direct
that the Securities of such series to be redeemed shall be selected from among groups of such Securities having specified Stated Maturities or rates of interest (or methods or computing interest) and the Trustee shall thereafter select the
particular Securities to be redeemed in the manner set forth above from among the groups of such Securities so specified. 

  
 31 

 The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall
relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed. 
 SECTION 1104.    Notice of Redemption. 
 Notice of redemption
shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. 

All notices of redemption shall state: 
 (1) the Redemption Date, 
 (2) the Redemption Price, 

(3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial
redemption, the principal amounts) of the particular Securities to be redeemed, 
 (4) in case any Security is to be redeemed in
part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed, 
 (5) that on the Redemption Date, the Redemption Price will become due and
payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date unless the Company defaults in making the redemption payment, 

(6) the place or places where such Securities are to be surrendered for payment of the Redemption Price, 

(7) that the redemption is for a sinking fund, if such is the case, 

(8) the CUSIP number, if any, printed on the Securities being redeemed, and 

(9) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the
Securities. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company
or, at the Company’s request, by the Trustee in the name and at the expense of the Company. In the case of redemptions by the Company of Global Securities, the Company shall, at least 30 days prior to the Redemption Date, notify the Depositary
(with a copy to the Trustee) of such redemption. 
 SECTION 1105.    Deposit of Redemption Price. 

On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as
its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date. 
 SECTION 1106.    Securities Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity
is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date according to their terms and the
provisions of Section 307. 
 If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 

  
 32 

 SECTION 1107.    Securities Redeemed in Part. 

Any security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the
Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so surrendered; provided, however, that the Depositary need not surrender Global Securities for a partial redemption and may be authorized to make a notation on such Global
Security of such partial redemption. In the case of a partial redemption of the Global Securities, the Depositary, and in turn, the participants in the Depositary, shall have the responsibility to select any Securities to be redeemed by random lot.

 ARTICLE TWELVE 
 SINKING FUNDS 
 SECTION 1201.    Applicability of Article. 

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 301 for Securities of such series. 
 The minimum amount of any sinking fund payment
provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to
as an “optional sinking fund payment.” If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the terms of Securities of such series. 
 SECTION
1202.    Satisfaction of Sinking Fund Payments with Securities. 
 The Company may, in satisfaction of all
or any part of any sinking fund payment with respect to the Securities of any series required to be made pursuant to the terms of such Securities as provided for by the terms of such series (1) deliver Outstanding Securities of such series
(other than any previously called for redemption) and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at
the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
 SECTION 1203.    Redemption of Securities for Sinking Fund. 

Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an
Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 1202, and the amount of any optional sinking fund payment to be added to the next ensuing sinking fund payment, and will also deliver to the
Trustee any Securities to be so delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein
specified. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107. 
 ARTICLE THIRTEEN 
 REPAYMENT AT THE OPTION OF HOLDERS 
 SECTION 1301.    Applicability of
Article. 
 Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall
be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such 

  
 33 

 
option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not operate as a payment, redemption or satisfaction of the
indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 1301, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the
Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the obligation of the Company to pay the repayment price of
such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers to the respective Holders thereof.

which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

 Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 SECTION 104.    Acts of Holders.

execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the
Company, if made in the manner provided in this Section. 
 (b) The fact and date of the execution by any person of any such
instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or
writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date
of the execution of any such instrument or writing, or the authority of the person executing the same, 

  
 5 

 
may also be proved in any other manner which the Trustee deems sufficient; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this
Section.

waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the
Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date, provided that no such authorization, agreement or consent by the Holders on
such record date shall be deemed effective unless it shall become effective pursuant to the provision of this Indenture not later than six months after the record date. 
 (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security
issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Security Registrar, any Paying Agent or the Company in reliance thereon,
whether or not notation of such action is made upon such Security. 
 SECTION 105.    Notices, Etc., to Trustee and Company.

 Except as otherwise specifically provided herein, any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 

(1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, or 
 (2) the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to the attention of its Treasurer at
[                    ] or any other address subsequently furnished in writing to the Trustee by the Company. 

SECTION 106.    Notice to Holders; Waiver. 
 Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage
prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice mailed in the manner prescribed
by this Indenture shall be conclusively presumed to have been duly given whether or not received by any particular Holder. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by reason of any other
cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 

In the case of Global Securities, notices or communications to be given to Holders shall be given to the Depository, in accordance with
its applicable policies from time to time. 
 SECTION 107.    Conflict with Trust Indenture Act. 

If any provision hereof limits, qualifies or conflicts with another provision hereof which is required to be included in this Indenture
by any of the provisions of the Trust Indenture Act, such required provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision
shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

113.    Legal Holidays. 
 In any case where any Interest Payment Date, Redemption Date, the Stated Maturity

or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date,
Redemption Date, at the Stated Maturity, or on the date for payment of Defaulted Interest, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or date for the payment of
Defaulted Interest, as the case may be, to the date of payment. 
 SECTION 114.    Indenture and Securities Solely Corporate
Obligations. 
 No recourse for the payment of the principal of (or premium, if any) or interest on any Security, or for any
claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture, or in any Security, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition
of, and as a consideration for, the execution of this Indenture and the issuance of the Securities. 
 SECTION
115.    Consent of Holders of Securities in a Foreign Currency or Euros. 
 Unless otherwise specified in a

amount of Securities of all series or all series affected by a particular action at the time Outstanding and, at such time, there are Outstanding Securities of any series which are denominated in a coin, currency or currency unit other than Dollars,

such Outstanding Securities at the Market Exchange Rate on the record date for the purpose of taking such action. If the appropriate Market Exchange Rate is not available for any reason with respect to such currency, the Trustee shall use, in its
sole discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York or, in the case of Euros, the rate of exchange as published in Journal, as of the most recent available date, or quotations or, in the case of
Euros, rates of exchange from one or more major banks in The City of New York or in the country of issue of the currency in question or, in the case of Euros, in Luxembourg or such other quotations or, in the case of Euros, rates of exchange as the

determinations of the Trustee regarding the Market Exchange Rate or any alternative determination provided for in the preceding paragraph shall be in its sole discretion and shall, in the absence
of manifest error, be conclusive for all purposes and irrevocably binding upon the Company and all Holders.

record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series. 

All Securities of any one series need not be issued at the same time, and may be issued from time to time, consistent with the terms of
this Indenture, if so provided by or pursuant to the Board Resolution, supplemental indenture or Officers’ Certificate referred to above. However, the authorized principal amount of any series may not be increased to provide for issuances of
additional Securities of such series, unless otherwise provided in such Board Resolution, supplemental indenture or Officers’ Certificate. 

SECTION 302.    Denominations. 
 The Securities of each series shall be issuable in registered form without coupons in such denominations as shall be specified as contemplated by Section 301. In the absence of any such provisions
with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof. 
 SECTION 303.    Execution, Authentication, Delivery and Dating. 
 The Securities shall be executed on behalf of the Company by any two of its Chairman of the Board, its President, any Vice President, its Treasurer or its Secretary, under its corporate seal reproduced
thereon. The signature of any of these officers on the Securities may be manual or facsimile. 
 Securities bearing the manual
or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of
such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver to the Trustee or an Authenticating Agent for authentication Securities of any series executed by the Company, together with a Company Order for the authentication and delivery of
such Securities, and the Trustee or such Authenticating Agent in accordance with the Company Order shall authenticate and deliver such Securities. If all the Securities of any series are not to be issued at one time, and if the Board Resolution,
Officers’ Certificate or supplemental indenture establishing such series shall so permit, such Company Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and the determination of the terms of particular
Securities of such series such as interest rate, maturity date, date of issuance and date from which interest shall accrue. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel stating, 
 (a) if the form of such Securities has been established by or
pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this Indenture; and 
 (b) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of
this Indenture. 

  
 10 

 If all the Securities of any series are not to be issued at one time, it shall not be
necessary to deliver an Opinion of Counsel at the time of issuance of each Security, but such Opinion of Counsel, with appropriate modifications, may instead be delivered at or prior to the time of issuance of the first Security of such series.

 The Trustee or any Authenticating Agent shall have the right to authenticate and deliver any of such Securities if it, being
advised by counsel, determines that such action may not lawfully be taken, or if it, its board of directors, trustees, executive committee, or a trust committee of directors or trustees and/or vice presidents shall determine in good faith that such
action would expose it to personal liability to existing Holders or if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee. 
 Each Security shall be dated the date of its authentication.

 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature, and such certificate upon any Security shall be conclusive evidence, and
the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 

SECTION 304.    Temporary Securities. 
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee or an Authenticating Agent shall authenticate and deliver, temporary Securities
which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 
 Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 

SECTION 305.    Registration, Registration of Transfer and Exchange. 

With respect to each series of Securities, the Company shall cause to be kept at one of the offices or agencies maintained pursuant to
Section 1002 a register (the register maintained in such office and in any other office or agency established by the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities of that series and of transfers of Securities of that series. Pursuant to Section 301, the Company shall appoint, with
respect to Securities of each series, a “Security Registrar” for the purpose of registering such Securities and transfers and exchanges of such Securities as herein provided. In the event the Trustee shall not be Security Registrar, it
shall have the right to examine the Security Register at all reasonable times. 
 Upon surrender for registration of transfer of
any Security of any series at the designated office or agency in a Place of Payment for that series, the Company shall execute, and the Trustee or an Authenticating Agent shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of the same series, of any authorized denominations and of a like tenor, aggregate principal amount and Stated Maturity. 
 At the option of the Holder, Securities of any series (except Global Securities) may be exchanged for other Securities of the same series, of any authorized denominations and of a like tenor, aggregate
principal amount and Stated Maturity, upon surrender of the Securities to be exchanged at such office or agency and upon payment, if the Company shall so require, of the charges hereinafter provided. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee or an Authenticating Agent shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or exchange shall (if so required by the Company or the Trustee or the Security Registrar) be duly endorsed, or be accompanied by a
written instrument of transfer in form satisfactory to the Company and the Security Registrar (and, if so required by the Trustee, to the Trustee) duly executed, by the Holder thereof or his attorney duly authorized in writing. 

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

  
 11 

 The Company shall not be required (i) to issue, register the transfer of or exchange
Securities of any series during a period beginning at the opening of business 15 days before the day of selection for redemption of Securities of that series selected for redemption under Section 1103 and ending at the close of business on the
day of the mailing of notice of redemption, or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

SECTION 306.    Mutilated, Destroyed, Lost and Stolen Securities. 

If there shall be delivered to the Company and the Trustee (i) a mutilated Security or evidence to their satisfaction of the
destruction, loss or theft of any Security and (ii) such security or indemnity bond as may be determined in the reasonable judgment of the Company or the Trustee, as the case may be, to protect the Company, the Trustee and any agent of either
of them from any loss which any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request
the Trustee or an Authenticating Agent shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security, a new Security of the same series and of like tenor, principal amount and Stated Maturity
and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series
issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities. 
 SECTION 307.    Payment of Interest; Interest Rights Preserved; Optional Interest Reset. 

(a) Except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, interest
on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest. 
 Any interest on any Security of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed
payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less
than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities
of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 

(2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be 

  
 12 

 
required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 

(b) The provisions of this Section 307(b) may be made applicable to any series of Securities pursuant to Section 301 (with such
modifications, additional or substitutions as may be specified pursuant to such Section 301). The interest rate on any Security of such series may be reset by the Company on the date or dates specified on the face of such Security (each an
“Optional Reset Date”). The Company may exercise such option with respect to a Security by notifying the Trustee of all of the relevant information relating to such exercise at least 50 but not more than 60 days prior to an Optional Reset
Date, the Trustee shall transmit, in the manner provided for in Section 106, to the Holder of any such Security a notice (the “Reset Notice”) indicating whether the Company has elected to reset the interest rate, and if so
(i) such new interest rate and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the Stated Maturity Date of such
Security (each such period a “Subsequent Interest Period”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period.

 Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the Company may, at its option,
revoke the interest rate provided for in the Reset Notice and establish a higher interest rate for the Subsequent Interest Period by causing the Trustee to transmit, in the manner provided for in Section 106, notice of such higher interest rate
to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest rate is reset on an Optional Reset Date will bear such higher interest rate. 

The Holder of any such Security will have the option to elect repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment
at the option of Holders, as such apply to such Security, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the holder has tendered
any Security for repayment pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset Date. 

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration
of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
 SECTION 308.    Persons Deemed Owners. 
 Prior to due
presentment of a Security for registration of transfer, the Company, the Trustee, any Paying Agent, any Authenticating Agent and any other agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the
owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 307) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue,
and neither the Company, the Trustee, any Paying Agent, any Authenticating Agent nor any other agent of the Company or the Trustee shall be affected by notice to the contrary. 
 None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial
ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the
Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any Depositary, as a Holder, with respect to such Global Security or impair, as between such
Depositary and owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security. 

SECTION 309.    Cancellation. 
 All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities shall be destroyed by the Trustee and the Trustee shall deliver a 

  
 13 

 
certificate of such destruction to the Company, unless the Company by Company Order shall direct that such cancelled Securities be returned to it. 

SECTION 310.    Computation of Interest. 
 Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day
months. 
 SECTION 311.    Global Securities. 
 If the Company shall establish pursuant to Section 301 that the Securities of a series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall
execute and the Trustee shall, in accordance with Section 303 and the Company Order with respect to such series, authenticate and deliver one or more Global Securities in temporary or permanent form that (i) shall represent and shall be
denominated in an amount equal to the aggregate principal amount of the outstanding Securities of such series to be represented by one or more Global Securities, (ii) shall be registered in the name of the Depositary for such Global Security or
Securities or the nominee of such depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instruction, and (iv) shall bear a legend substantially to the following effect: “This
Security is a Global Security within the meaning of the Indenture hereinafter referred to, and is registered in the name of the Depository or a nominee of the Depository. This Security is exchangeable for Securities registered in the name of a
Person other than the Depository or its nominee only in the limited circumstances described in the Indenture, and may be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary
or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.” The Trustee shall deal with the Depositary and its participants as representatives of the
Beneficial Owners of the Global Securities for purposes of exercising the rights of the Holders hereunder and the rights of the Beneficial Owners of the Global Securities shall be limited to those established by law and agreements between such
Beneficial Owners and the Depositary and its participants. Beneficial Owners shall not be entitled to certificates for Global Securities as to which they are the Beneficial Owners. Requests and directions from, and votes of, such representatives
shall not be deemed to be inconsistent if they are made with respect to different Beneficial Owners. 
 Notwithstanding any
other provision of this Section or Section 305, unless and until it is exchanged in whole or in part for Securities in definitive form, a Global Security representing all or a portion of the Securities of a series may not be transferred except
as a whole by the Depositary for such series to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such
series or a nominee of such successor depositary. The Beneficial Owner’s ownership of Securities shall be recorded on the records of a participant of the Depositary that maintains such Beneficial Owner’s account for such purpose and the
participant’s record ownership of such Securities shall be recorded on the records of the Depositary. 
 If at any time the
Depositary for the Securities of a series notifies the Company that it is unwilling or unable to continue as Depositary for the Securities of such series or if at any time the Depositary for Securities of a series ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, the Company shall appoint a successor Depositary with respect to the Securities of such series. If a successor Depositary for the Securities
of such series is not appointed by the Company within 90 days after the Company receives written notice or becomes aware of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and
delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series, with like tenor and terms, in definitive form in an aggregate principal amount equal to the principal amount of the Global Security or
Securities representing such series in exchange for such Global Security or Securities. 
 The Company may at any time and in
its sole discretion determine that the Securities of any series issued in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event, the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series, with like tenor and terms, in definitive form and in an aggregate principal amount
equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities. 
 If specified by the Company pursuant to Section 301 with respect to Securities of a series, the Depositary for such series of Securities may surrender a Global Security for such series of Securities
in exchange in whole or in part for Securities of such series in definitive form on such terms as are acceptable to the Company and such Depositary. Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without charge,

 (i) to each Person specified by the Depositary a new Security or Securities of the same series of like tenor and terms of any
authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and 

  
 14 

 (ii) to the Depositary a new Global Security in a denomination equal to the difference, if
any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Securities delivered to Holders thereof. 
 Upon the exchange of a Global Security for Securities in definitive form, such Global Security shall be cancelled by the Trustee. Securities issued in exchange for a Global Security pursuant to this
Section shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall
deliver such Securities to the persons in whose names such Securities are so registered. 
 The Depository, as a Holder, may
appoint agents and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under this Indenture. 

Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 301, payment of the
principal of, and interest and premium, if any, on, any Global Security shall be made to the Depository or its nominee in its capacity as the Holder thereof. Further, the Company, the Trustee and any Authentication Agent shall treat a Person as the
Holder of such principal amount of outstanding Securities of any series represented by a Global Security as shall be specified in a written statement of the Depository (which may be in the form of a participants’ list for such series) 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, provided, that until the Trustee is so provided with a written statement, it
may treat the Depository or any other Person in whose name a Global Security is registered as the owner of such Global Security for all purposes, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary. 
 SECTION 312.    Optional Extension of Maturity. 

The provisions of this Section may be made applicable to any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 301). The Stated Maturity of any Security of such series may be extended at the option of the Company for the period or periods specified on the face of such Security (each
an “Extension Period”) up to but not beyond the date (the “Final Maturity”) set forth on the face of such Security. The Company may exercise such option with respect to any Security by notifying the Trustee of such exercise at
least 50 but not more than 60 days prior to the Stated Maturity of such Security in effect prior to the exercise of such (the “Original Stated Maturity”). If the Company exercises such option, the Trustee shall transmit, in the manner
provided for in Section 106, to the Holder of such Security not later than 40 days prior to the Original Stated Maturity a notice (the “Extension Notice”) indicating (i) the election of the Company to extend the Maturity,
(ii) the new Stated Maturity Date, (iii) the interest rate applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustee’s transmittal of the Extension Notice,
the Stated Maturity Date of such Security shall be extended automatically and, except as modified by the Extension Notice and as described in the next paragraph, such Security will have the same terms as prior to the transmittal of such Notice.

 Notwithstanding the foregoing, not later than 20 days before the Original Stated Maturity of such Security, the Company may,
at its option, revoke the interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to transmit, in the manner provided for in Section 106, notice of such higher
interest rate to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate. 

If the Company extends the Maturity of any Security, the Holder will have the option to elect repayment of such Security by the Company
on the Original Stated Maturity at a price equal to the outstanding principal amount thereof, plus interest accrued to such date. In order to obtain repayment on the Original Stated Maturity once the Company has extended the Maturity thereof, the
Holder of an Outstanding Security must follow the procedures set forth in Article Thirteen for repayment at the option of Holders, as such applies to the Securities of such series, except that the period for delivery or notification to the Trustee
shall be at least 25 but not more than 35 days prior to the Original Stated Maturity and except that, if the Holder has tendered any Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such
tender for repayment until the close of business on the tenth day before the Original Stated Maturity unless the Trustee has previously delivered repayment of such Security to such Holder. 
 SECTION 313.    CUSIP and ISIN Numbers. 
 The Company in
issuing the Securities may use one or more “CUSIP” and “ISIN” numbers (if then generally in use), and, if the Company does so, the Trustee shall use the CUSIP number(s) and ISIN numbers in notices of redemption or exchange as a
convenience to Holders, provided, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP and ISIN number(s) printed in the notice or on the Securities, and that reliance may be placed only on the
other identification numbers printed on the Securities, and that any such redemption or exchange shall not be affected by any defect in or omission of any such numbers.

 ARTICLE FOUR 
 SATISFACTION AND DISCHARGE 
 SECTION 401. Satisfaction and Discharge of Securities of any Series.

 The Company shall be deemed to have satisfied and discharged the entire indebtedness on all the Securities of any particular
series and the Trustee, upon Company request and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of such indebtedness, when 

(1) either: 

    (A) all Securities of such series theretofore authenticated and delivered (other than (i) Securities which
have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and
thereafter repaid to the Company or discharged from such trust, as provided in the last paragraph of Section 1003) have been delivered to the Trustee for cancellation; or 
     (B) with respect to all Outstanding Securities of such series described in (A) above not theretofore delivered to the Trustee for cancellation, 

(i) The Company has deposited or caused to be deposited with the Trustee as trust funds in trust an amount sufficient to pay and
discharge the entire indebtedness on all such Outstanding Securities of such series for principal (and premium, if any) and interest to the Stated Maturity or any Redemption Date as contemplated by Section 403, as the case may be; or

 (ii) The Company has deposited or caused to be deposited with the Trustee as obligations in trust such amount of direct
obligations of, or obligations the principal of and interest on which are fully guaranteed by, the United States of America (other than obligations subject to prepayment, redemption or call prior to their stated maturity) as will, together with the
predetermined and certain income to accrue thereon (without consideration of any reinvestment thereof), be sufficient to pay and discharge when due the entire indebtedness on all such Outstanding Securities of such series for principal (and premium,
if any) and interest to the Stated Maturity or any Redemption Date as contemplated by Section 403, as the case may be; 

(2) the Company has paid or caused to be paid all other sums payable with respect to the Securities of such series; 

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of the entire indebtedness on all Securities of such series have been complied with; and 
 (4) if the entire indebtedness on the Outstanding Securities of such series is to be satisfied and discharged pursuant to Section 401(l)(B) above, then (i) the Company shall have specified the
applicability (as provided in Section 301) of this Section 401(4) to the Securities of such series, (ii) the Company shall have given, not later than the date of such deposit, notice of such deposit to the Holders of Securities of
such series and (iii) the Trustee shall have received an Opinion of Counsel (which Counsel shall be recognized tax counsel) stating that, (x) the Company has received from the Internal Revenue Service a ruling or (y) since the date of
this Indenture, there has been a change in the applicable federal income tax law, including by means of a Revenue Ruling published by the Internal Revenue Service, in either case to the effect that, and based thereon such Opinion of Counsel will
confirm that the deposit of funds or obligations and the satisfaction and discharge of indebtedness on the Securities of such series pursuant to this Section will not result in recognition by the Holders of income, gain or loss for federal income
tax purposes (other than income, gain or loss which would have been recognized in like amount and at a like time absent such deposit, satisfaction and discharge), provided that the Company will be discharged from the requirements of Article Eight if
(i) it has satisfied all of the requirements for satisfaction and discharge of the indebtedness on the Outstanding Securities pursuant to Section 401(1)(B) except for the delivery of the Opinion of Counsel described above, and
(ii) the Trustee shall have received an Opinion of Counsel stating that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of the deposit of such funds or obligations and will be subject to federal
tax in the same amounts, in the same manner and at the same times as would have been the case if such deposit of funds or obligations had not occurred. 
 Upon the satisfaction of the conditions set forth in this Section with respect to all the Securities of any series, the terms and conditions of such series, including the terms and conditions with respect
thereto set forth in this Indenture, shall no longer be binding upon, or applicable to, the Company, and the Holders of the Securities of such series shall look for payment only to the funds or obligations deposited with the Trustee pursuant to
Section 401(l)(B); provided, however, that, in no event shall the Company be discharged (a) from any payment obligations in respect of Securities of such series which are deemed not to be Outstanding under clause (iii) of the
definition thereof if such obligations continue to be valid obligations of the Company under applicable law, (b) from any obligations under Section 607 or the last paragraph of Section 1003, and (c) from any obligations under
Section 305 and 306 (except that Securities of such series issued upon registration of transfer or exchange or in lieu of mutilated, lost, destroyed or stolen Securities shall not be obligations of the Company), and Section 701.

 SECTION 402.    Satisfaction and Discharge of Indenture. 

Upon compliance by the Company with the provisions of Section 401 as to the satisfaction and discharge of each series of Securities
issued hereunder, this Indenture shall cease to be of any further effect (except as otherwise provided herein). Upon Company Request (and at the expense of the Company), the Trustee shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture. In the event there are two or more Trustees hereunder, then the effectiveness of any such instrument shall be conditioned upon receipt of such instruments from all Trustees hereunder. 

Notwithstanding the satisfaction and discharge of this Indenture, any obligations of the Company under Sections 305, 306, 607 and 701 and
the last paragraph of Section 1003, and of the Trustee under Sections 403 and 613 and the last two paragraphs of Section 1003, shall survive. 
 SECTION 403.    Application of Trust Money. 
 Subject to the
provisions of the last two paragraphs of Section 1003, all money and obligations deposited with the Trustee pursuant to Section 401 shall be held irrevocably in trust and shall be made under the terms of an escrow trust agreement in form
and substance satisfactory to the Trustee. Such money and obligations shall be applied by the Trustee, in accordance with the provisions of the Securities, this Indenture and such escrow trust agreement, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal of (and premium, if any) and interest, if any, on the Securities for the payment of which such
money and obligations have been deposited with the Trustee (but such money need not be segregated from other funds except to the extent required by law). If Securities of any series are to be redeemed prior to their Stated Maturity, whether pursuant
to any optional redemption provisions or in accordance with any mandatory sinking fund requirement, the Company shall make such arrangements as are satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at
the expense, of the Company. 
 ARTICLE FIVE 
 REMEDIES 
 SECTION 501.    Events of Default. 

“Event of Default,” wherever used herein with respect to Securities of any series, means any one of the following events
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body): 
 (1) default in the payment of any interest upon any Security of that series when it becomes due and
payable, and continuance of such default for a period of 30 days; or 
 (2) default in the payment of the principal of (or
premium, if any, on) any Security of that series at its Maturity; or 
 (3) default in the deposit of any sinking fund payment,
when and as due by the terms of a Security of that series; or 
 (4) default in the performance, or breach, of any covenant or
agreement of the Company in this Indenture (other than a covenant or agreement a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee
by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default”
hereunder; or 
 (5) the Company pursuant to or within the meaning of any Bankruptcy Law: 

    (A) commences a voluntary case, 
     (B) consents to the entry of an order for relief against it in an involuntary case, 
     (C) consents to the appointment of a Custodian of it or for all or substantially all of its property, or 
     (D) makes a general assignment for the benefit of its creditors; or 
 (6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

  
 17 

     (A) is for relief against the Company in an involuntary case;

     (B) appoints a Custodian of the Company or for all or substantially all of its property, or

     (C) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for
60 days. 
 The term “Bankruptcy Law” means Title 11 of the U.S. Code or any similar Federal or State law for the
relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 
 (7) any other Event of Default provided with respect to the Securities of that series pursuant to Section 301 or in a supplemental indenture. 
 SECTION 502.    Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal
amount of the outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series)
of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified portion) shall become
immediately due and payable. 
 Upon payment of such amount, all obligations of the Company in respect of the payment of
principal of the Securities of such series shall terminate. 
 At any time after such a declaration of acceleration with respect
to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding
Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay 

    (A) all overdue interest, if any, on all Securities of that series, 

    (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than
by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities, 

    (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates,
if any, prescribed therefor in such Securities, and 
     (D) all sums paid or advanced by the Trustee
hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that
series which have become due solely by such declaration of acceleration, have been cured, or waived as provided in Section 513. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 

SECTION 503.    Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if: 
 (1) default is made in the payment of any interest on any Security of any series when such interest becomes due and payable and such default continues for a period of 30 days, or 

(2) default is made in the payment of the principal of (or premium, if any, on) any Security of any series at the Maturity thereof, the
Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of Securities of such series, the whole amount then due and payable on Securities of such series for principal (and premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates, if any, prescribed therefor in such Securities; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

  
 18 

 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its
own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other
obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. 

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement
of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 

SECTION 504.    Trustee May File Proofs of Claim. 
 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other
obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration of
acceleration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

 (i) to file and prove a claim for the whole amount of principal (or with respect to Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of such Securities), and premium, if any and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order
to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or
the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION
505.    Trustee May Enforce Claims Without Possession of Securities. 
 All rights of action and claims
under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for
the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
 SECTION
506.    Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article shall
be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee
under Section 607; 
 SECOND: To the payment of all Senior Indebtedness if and to the extent required by Article Fourteen
or other subordination provisions applicable with respect to a series of Securities; and 
 THIRD: To the payment of the amounts
then due and unpaid for principal of (and premium, if any) and interest, if any, on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the
amounts due and payable on such Securities for principal (and premium, if any) and interest, if any, respectively; and 

FOURTH: The balance, if any, to the Company, its successor or assigns or to whoever may be lawfully entitled to receive the same or as a
court of competent jurisdiction may direct. 

  
 19 

 SECTION 507.    Limitation on Suits. 

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) An Event of Default
shall have occurred and be continuing with respect to the Securities of that series and such Holder shall have previously given written notice thereof to the Trustee; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of
Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee reasonable indemnity
against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 
 (5) no direction
inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or
prejudice the rights of any other Holder or to obtain or to seek to obtain priority or preference over any other Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all
Holders of Securities of such series. 
 SECTION 508.    Unconditional Right of Holders to Receive Principal, Premium and
Interest. 
 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is
absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 307) interest, if any, on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 SECTION 509.    Restoration of Rights and Remedies. 
 If the
Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted. 
 SECTION 510.    Rights and Remedies
Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 511.    Delay or
Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 SECTION
512.    Control by Holders. 
 The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series,
provided that 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture, 

  
 20 

 (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction, 
 (3) such direction is not unduly prejudicial to the rights of other Holders, and

 (4) such direction would not involve the Trustee in personal liability. 

SECTION 513.    Waiver of Past Defaults. 
 The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder
with respect to such series and its consequences, except a default 
 (1) in the payment of the principal of (or premium, if
any) or interest, if any (subject to the provisions of Section 502), on any Security of such series, or 
 (2) in respect
of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series 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 the Securities of such series under this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 SECTION 514.    Undertaking for Costs. 
 All parties to this
Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys’ fees at trial and on appeal, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall
not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any
series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date). 
 ARTICLE SIX 

THE TRUSTEE 
 SECTION
601.    Certain Duties and Responsibilities. 
 (a) Except during the continuance of an Event of Default,

 (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and
no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad
faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture; but in the case of any such certificate or opinion which by any provision hereof is specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not it conforms to the
requirements of this Indenture. 
 (b) In case an Event of Default has occurred and is continuing, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that 
 (1) this Subsection shall not be construed to limit the
effect of Subsection (a) of this Section; 

  
 21 

 (2) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 
 (3) the
Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities of any series, as
provided in Section 512, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the
Securities of such series; and 
 (4) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity
against such risk or liability is not reasonably assured to it. 
 (d) Whether or not herein expressly so provided, every
provision of this Indenture relating to the conduct of or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
 SECTION 602.    Notice of Defaults. 
 Within 90 days after the
occurrence of any default hereunder with respect to the Securities of any series, the Trustee shall transmit by mail to all Holders of Securities of such series, as their names and addresses appear in the Security Register, notice of such default
hereunder actually known to a Responsible Officer of the Trustee, unless such default shall have been cured or waived; provided, however, that except in the case of a default in the payment of the principal of (or premium, if any) or interest, if
any, on any Security of such series, in the payment of any sinking fund installment with respect to Securities of such series or in the payment of the Redemption Price of any Securities as to which notice of redemption has been given, the Trustee
shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is
in the interest of the Holders of Securities of such series; and provided, further, that in the case of any default of the character specified in Section 501(4) with respect to Securities of such series, no such notice to Holders shall be given
until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of
such series. 
 SECTION 603.    Certain Rights of Trustee. 

Subject to the provisions of Section 601: 
 (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order,
bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 

(b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and
any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 
 (c) whenever in the

the absence of bad faith on its part, rely upon an Officers’ Certificate; 
 (d) the Trustee may consult with counsel and
the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 

(e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such
request or direction; 
 (f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit; 
 (g) the Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney, including any Authenticating Agent,
appointed with due care by it hereunder; 

  
 22 

 (h) the Trustee shall not be liable for any action taken or omitted by it in good faith and
believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; and 
 (i) the
Trustee shall not be charged with knowledge of any Event of Default with respect to the Securities of any series for which it is acting as Trustee unless either (1) a Responsible Officer of the Trustee assigned to the Corporate Trust Office of
the Trustee (or any successor division or department of the Trustee) shall have actual knowledge of the Event of Default or (2) written notice of such Event of Default shall have been given to the Trustee by the Company, any other obligor on
such Securities or by any Holder of such Securities. 
 SECTION 604.    Not Responsible for Recitals or Issuance of
Securities. 
 The recitals contained herein and in the Securities, except certificates of authentication, shall be taken as the
statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof. 

SECTION 605.    May Hold Securities. 
 The Trustee, any Authenticating Agent, any Paying Agent, the Security Registrar or any other agent of the Company or the Trustee, in their individual or any other capacity, may become the owner or pledgee
of Securities and, subject to Sections 608 and 612, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 

SECTION 606.    Money Held in Trust. 
 Money held by the Trustee or any Paying Agent in trust hereunder need not be segregated from other funds except to the extent required by law. Neither the Trustee nor any paying Agent shall be subject to
any liability for interest on any money received by it hereunder except as otherwise agreed with the Company. 
 SECTION
607.    Compensation and Reimbursement. 
 The Company agrees: 

(1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall
not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
 (2) except as
otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 

(3) to indemnify the Trustee and its agents for, and to hold them harmless against, any loss, liability or expense incurred without
negligence or bad faith on their part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending themselves against any claim or liability in connection with
the exercise or performance of any of their powers or duties hereunder. 
 As security for the performance of the obligations of
the Company under this Section, the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal (or premium, if any) or interest, if
any, on Securities. 
 The provisions of this Section shall survive the resignation or removal of the Trustee or the discharge
of this Indenture. When the Trustee incurs expenses after the occurrence of an Event of Default specified in Section 501(5) or (6) the expenses are intended to constitute expenses of administration under any Bankruptcy Law. The obligations
of the Company under this Section shall not be subordinated to the payment of Senior Indebtedness. 
 SECTION
608.    Corporate Trustee Required; Eligibility; Conflicting Interests. 
 This Indenture shall always have
a Trustee who satisfies the requirements of Trust Indenture Act Sections 310(a)(1), (2) and (5) in every respect. The Trustee (or in the case of a Trustee that is a Person included in a bank holding company system, the related bank holding
company) shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act Section 310(b), including the provision in
Section 310(b)(1). In addition, if the Trustee is a Person included in a bank holding company system, the Trustee, independently of such bank holding company, shall meet the capital requirements of Trust Indenture Act Section 310(a)(2). If
at any time the Trustee shall cease to be 

  
 23 

 
eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Article. 

SECTION 609.    Resignation and Removal; Appointment of Successor. 

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee or Trustees pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee or Trustees in accordance with the applicable requirements of Section 610. 
 (b) The Trustee may resign at any time with respect to the Securities of one or more series by notifying the Company in writing at least 90 days in advance of such resignation. If the instrument of
acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 60 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such series. 
 (c) The Trustee may be removed at any time
with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 

(d) If at any time the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder
who has been a bona fide Holder of a Security for at least six months, the Company by a Board Resolution may remove the Trustee with respect to the Securities of such series or, subject to Section 514, any Holder who has been a bona fide Holder
of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to the Securities of such series and the
appointment of a successor Trustee. 
 (e) If at any time: 

(1) the Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by the Company
or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall become
incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 
 then, in any such case, (i) the Company by a Board Resolution may remove the Trustee with
respect to all Securities, or (ii) subject to Section 514, any holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
 (f) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 610. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of
such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 610, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company with respect to such series. If no successor Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders of the Securities of such series and accepted appointment in the manner required by Section 610, any Holder who has been a bona fide holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

(g) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and
each appointment of a successor Trustee with respect to the Securities of any series by mailing written notice of such event by first-class mail, postage prepaid, to all Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
 SECTION 610.    Acceptance of Appointment by Successor. 
 (a)
In case of the appointment hereunder of a successor Trustee with respect to all series of Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting
such 

  
 24 

 
appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested
with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges due pursuant to Section 607, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder subject
to the lien provided in Section 607. 
 (b) In case of the appointment hereunder of a successor Trustee with respect to the
Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor
Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all series of Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities or that or those series as to which the retiring Trustee is not retiring shall continue to be
vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood
that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee
relates; but, on request of the Company or any successor Trustee, such retiring trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities
of that or these series to which the appointment of such successor Trustee relates. 
 (c) Upon request of any such successor
Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case
may be. 
 (d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee
shall be qualified and eligible under this Article. 
 SECTION 611.    Merger, Conversion, Consolidation or Succession to
Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities. 
 SECTION 612.    Preferential Collection of Claims
Against Company. 
 The Trustee shall comply with Trust Indenture Act Section 311(a), excluding any creditor relationship
listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated therein. 
 SECTION 613.    Appointment of Authenticating Agent. 
 At any
time when any of the Securities remain Outstanding the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate and deliver
Securities of such series with respect to which it has been so designated, and Securities so authenticated and delivered shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by
the Trustee hereunder. 
 Wherever reference is made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the
Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a bank or trust company or corporation organized and doing business and in good standing under the laws of the United States,
any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $100,000,000 and subject to 

  
 25 

 
supervision or examination by Federal, State or District of Columbia authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in
this Section. 
 Any corporation into which an Authenticating Agent may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating
Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

 An Authenticating Agent may resign with respect to one or more series of Securities at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent with respect to one or more series of Securities by giving written notice thereof to such Authenticating Agent and to the Company.
Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all holders of Securities of the series with respect to which such Authenticating Agent will serve, as their
names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
 The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section. The provisions of Sections 104, 111, 603, 604 and 605 shall be
applicable to any Authenticating Agent. 
 Pursuant to each appointment made under this Section, the Securities of each series
covered by such appointment may have endorsed thereon, in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication in substantially the following form: 

This is one of the Securities, of the series designated herein, issued under the within-mentioned Indenture.

supplementary and periodic information, documents and reports which may be required under Section 13 of the Securities Exchange Act of 1934, as amended. The Company will also comply with the other provisions of Trust Indenture Act
Section 314(a). All information, documents and reports to be provided pursuant to this Section will be deemed to be so delivered to the Trustee when the Company files such information, documents and reports with the Commission through the

into, or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets (as an entirety or substantially as an entirety in one transaction or a series of related transactions), to any Person or

be a corporation organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and shall expressly assume by a supplemental indenture executed and delivered to the Trustee, in form reasonably
satisfactory to the Trustee, all of the obligations of the Company (including, without limitation, the obligation to pay the principal of, and premium and interest, if any, on, the Securities and the performance of the other covenants) under the

SUPPLEMENTAL INDENTURES 

SECTION 901.    Supplemental Indentures Without Consent of Holders. 

Without the consent of any Holder, the Company, when authorized by a Board Resolution, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes: 
 (1) to evidence the succession of another corporation to the Company and the assumption by any such successor of the covenants of the Company herein and in the Securities; or 

(2) to add to the covenants of the Company for the benefit of the Holders of all or any series of Securities (and if such covenants are
to be for the benefit of less than all series of Securities, stating that such covenants are expressly being included solely for the benefit of such series) or to surrender any right or power herein conferred upon the Company; provided, however,
that in respect of any such additional covenant, such supplemental indenture may provide for a particular period of grace after default in the performance of such covenant (which period may be shorter or longer than that allowed in the case of other
defaults) or may provide for an immediate enforcement upon such default or may limit the remedies available to the Trustee upon such default; or 
 (3) to add any additional Events of Default; or 
 (4) add to or change or
eliminate any of the provisions of this Indenture to extent as shall be necessary to permit or facilitate the issuance of Securities in bearer form, registrable or not registrable as to principal, and with or without interest coupons; or 

(5) to change or eliminate any of the provisions of this Indenture, provided that any such change or elimination shall become effective
only when there is no Security Outstanding of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision; or 
 (6) to secure the Securities; or 
 (7) to establish the form or terms of
Securities of any series as permitted by Sections 201 and 301; or 
 (8) to evidence and provide for the acceptance of
appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, pursuant to the requirements of Section 610(b); or 
 (9) to cure any ambiguity, to
correct or supplement any provision herein which may be inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Indenture, provided such action shall not adversely affect
the interests of the Holders of Securities of any series in any material respect. 
 SECTION 902.    Supplemental Indentures
with Consent of Holders. 
 With the consent of the Holders of not less than a majority in principal amount of the Outstanding
Securities of each series (each such series voting as a separate class) affected by such supplemental indenture, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of
Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby, 

(1) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the
principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or modify the manner of determination of the rate of interest thereon so as to affect adversely the interest of such Holder or reduce the
amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502, or change any Place of Payment where, or the coin or currency in
which, any Security or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption

the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences)
provided for in this Indenture, or 
 (3) modify any of the provisions of this Section, Section 513 or Section 1006,
except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby, provided, however, that this clause
shall not be deemed to require the consent of any Holder with respect to changes in the references to the “Trustee” and concomitant changes in this Section and Section 1006, or the deletion of this proviso, in accordance with the
requirements of Sections 610(b) and 901(8). 
 A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. 

The Trustee may in its discretion determine whether or not any Securities would be affected by any supplemental indenture and any such
determination shall he conclusive upon the Holders of all Securities of any series. The Trustee shall not be liable for any such determination made in good faith. 
 It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the
substance thereof. 
 SECTION 903.    Execution of Supplemental Indentures. 

In executing or accepting the additional trusts created by any supplemental indenture permitted by this Article or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be provided, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized
or permitted by this Indenture and that such supplemental indenture, when executed and delivered by the Company, will constitute a valid and binding obligation of the Company in accordance with its terms. The Trustee may, but shall not be obligated
to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 SECTION 904.    Effect of Supplemental Indentures. 
 Upon the
execution of any supplemental indenture pursuant to the provisions of this Article, this Indenture shall, with respect to such series, be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders of Securities of the series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such supplemental indenture, with respect to such series, shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

SECTION 905.    Conformity with Trust Indenture Act. 
 Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act of 1939, as amended, in effect on such date. 

SECTION 906.    Reference in Securities to Supplemental Indentures. 

Securities of any series, affected by a supplemental indenture, authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any
series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee or any Authenticating Agent in
exchange for Outstanding Securities of such series. 
 ARTICLE TEN 

COVENANTS 
 SECTION
1001.    Payment of Principal, Premium and Interest. 
 The Company covenants and agrees that it will duly
and punctually pay the principal of (and premium, if any) and interest, if any, on the Securities of each series in accordance with the terms of the Securities of such series and this Indenture. 

  
 29 

 SECTION 1002.    Maintenance of Office or Agency. 

The Company will cause to be maintained in each Place of Payment for any series of Securities an office or agency where Securities of
that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. With respect to the Securities of any series such office or agency and each place of
Payment shall be as specified as contemplated in Section 301. In the absence of any such provisions with respect to the Securities of any series (i) the place of payment for such securities shall be the Borough of Manhattan, City of New
York, New York, and (ii) such office or agency in such Place of Payment shall be the Corporate Trust Office of the Trustee therein. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands. 
 The Company may also from time to time designate one or more other offices or agencies (in
or outside the Borough of Manhattan, City of New York, New York) where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no
such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location of any such office or agency. 
 SECTION
1003.    Money for Securities Payments to Be Held in Trust. 
 If the Company shall at any time act as its
own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest, if any, on any of the Securities of that series, segregate and hold in trust for the benefit of the
persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest, if any, so becoming due until such sums shall be paid to such persons or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents for any series of Securities,
it will, on or before each due date of the principal of (and premium, if any) or interest, if any, on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest, if any, so
becoming due, such sum to be held in trust for the benefit of the persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

 The Company will cause each Paying Agent other than the Trustee for any series of Securities to execute and deliver to the
Trustee an instrument in which such paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 
 (1) hold all sums held by it as agent for the payment of the principal of (and premium, if any) or interest, if any, on Securities of that series in trust for the benefit of the Persons entitled thereto
until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
 (2) give the Trustee written
notice within three Business Days of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest, if any, on the Securities of that series; and

 (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the
Trustee all sums so held in trust by such Paying Agent. 
 The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any paying Agent to the Trustee, such paying agent shall be released from all further liability with respect to such money. Upon the
satisfaction and discharge of the indebtedness in respect of all Outstanding Securities of any series all sums then held by any Paying Agent (other than the Trustee) in respect thereof shall, upon demand of the Company, be repaid to it or paid to
the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such money. 
 The
Trustee and any Paying Agent shall promptly pay to the Company upon Company Request any money or securities held by them at any time in excess of amounts necessary to satisfy amounts payable to the Holders, the Trustee and the Paying Agent.

  
 30 

 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium, if any) or interest, if any, on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest, if any, has become due and payable
shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in each Place of Payment with respect to Securities of such series,
notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will, unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property law, be repaid to the Company.

1004.    Corporate Existence. 
 Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate existence. 
 SECTION 1005.    Statement as to
Compliance.

after the date hereof, an Officers’ Certificate which complies with Trust Indenture Act Section 314(a)(4) and need not comply with Section 102, stating as to each signer thereof that 

(1) a review of the activities of the Company during such year and of performance under this Indenture has been made under his
supervision, and 
 (2) as of the end of such year and at the date of the certificate to the best of his knowledge, based on
such review, (a) the Company is not in default in the fulfillment of any of its obligations under this Indenture, or specifying each such default known to him and the nature and status thereof and (b) no event has occurred and is
continuing which is or after notice or lapse of time or both would become an Event of Default, or, if such an event has occurred and is continuing, specifying each such event known to him and the nature and status thereof. 

SECTION 1006.    Waiver of Certain Covenants. 
 The Company may omit in any particular instance to comply with any covenant or condition set forth in Sections 1002 to 1005, each inclusive, or a supplemental indenture with respect to the Securities of
any series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee with respect to any such covenant or condition shall remain in full force and effect. 
 ARTICLE ELEVEN

 REDEMPTION OF SECURITIES 
 SECTION 1101.    Applicability of Article. 
 Securities of any
series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article.

 SECTION 1102.    Election to Redeem; Notice to Trustee. 

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election
of the Company of less than all the Securities of any series, the Company shall, at least 45 days (unless a shorter notice shall be satisfactory to the Trustee) prior to the Redemption Date fixed by the Company (unless a shorter notice, but not less
than 30 days, shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an 

  
 31 

 
Officers’ Certificate evidencing compliance with such restriction. Any such notice may be canceled at any time prior to notice of such redemption being mailed to any Holder, and shall
thereby be void and of no effect. 
 SECTION 1103.    Selection by Trustee of Securities to be Redeemed. 

If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected by the
Trustee not more than 45 days prior to the Redemption Date, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized
denomination for Securities of that series. In any case where Securities of such series are registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Security
of such series. If the Securities of any series to be redeemed consist of Securities having different Stated Maturities or different rates of interest (or methods of computing interest), then the Company may, by written notice to the Trustee, direct
that the Securities of such series to be redeemed shall be selected from among groups of such Securities having specified Stated Maturities or rates of interest (or methods or computing interest) and the Trustee shall thereafter select the
particular Securities to be redeemed in the manner set forth above from among the groups of such Securities so specified. 
 The
Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall
relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed. 
 SECTION 1104.    Notice of Redemption. 
 Notice of redemption
shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. 

All notices of redemption shall state: 
 (1) the Redemption Date, 
 (2) the Redemption Price, 

(3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial
redemption, the principal amounts) of the particular Securities to be redeemed, 
 (4) in case any Security is to be redeemed in
part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed, 
 (5) that on the Redemption Date, the Redemption Price will become due and
payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date unless the Company defaults in making the redemption payment, 

(6) the place or places where such Securities are to be surrendered for payment of the Redemption Price, 

(7) that the redemption is for a sinking fund, if such is the case; 

(8) the CUSIP number, if any, printed on the Securities being redeemed; and 

(9) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the
Securities. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company
or, at the Company’s request, by the Trustee in the name and at the expense of the Company. In the case of redemptions by the Company of Global Securities, the Company shall, at least 30 days prior to the Redemption Date, notify the Depositary
(with a copy to the Trustee) of such redemption. 

  
 32 

 SECTION 1105.    Deposit of Redemption Price. 

On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as
its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date. 
 SECTION 1106.    Securities Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity
is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date according to their terms and the
provisions of Section 307. 
 If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
 SECTION 1107.    Securities Redeemed in Part. 
 Any security
which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee
duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of
the same series, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered; provided, however, that the Depositary
need not surrender Global Securities for a partial redemption and may be authorized to make a notation on such Global Security of such partial redemption. In the case of a partial redemption of the Global Securities, the Depositary, and in turn, the
participants in the Depositary, shall have the responsibility to select any Securities to be redeemed by random lot. 
 ARTICLE
TWELVE 
 SINKING FUNDS 

SECTION 1201.    Applicability of Article. 
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 301 for Securities of such
series. 
 The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein
referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment.” If provided
for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series. 
 SECTION 1202.    Satisfaction of Sinking Fund Payments with
Securities. 
 The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of
any series required to be made pursuant to the terms of such Securities as provided for by the terms of such series (1) deliver Outstanding Securities of such series (other than any previously called for redemption) and (2) apply as a
credit Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 

  
 33 

 SECTION 1203.    Redemption of Securities for Sinking Fund. 

Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an
Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 1202, and the amount of any optional sinking fund payment to be added to the next ensuing sinking fund payment, and will also deliver to the
Trustee any Securities to be so delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein
specified. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107. 
 ARTICLE THIRTEEN 
 REPAYMENT AT THE OPTION OF HOLDERS 
 SECTION 1301.    Applicability of
Article. 
 Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall
be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of
Section 309, shall not operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that
such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such
Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers to the respective Holders thereof. 

ARTICLE FOURTEEN 

SUBORDINATION 
 SECTION
1401.    Securities Subordinated to Senior Indebtedness. 
 The Company covenants and agrees, and each
Holder of Securities by his acceptance thereof, likewise covenants and agrees, that the indebtedness evidenced by the Securities and the payment of the principal of (and premium, if any) and interest on each and all of the Securities is hereby
expressly subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of Senior Indebtedness. 
 Anything in this Indenture or in the Securities to the contrary notwithstanding, the indebtedness evidenced by the Securities shall be subordinate and junior in right of payment, to the extent and in the
manner hereinafter set forth, to all Senior Indebtedness. Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of these subordination provisions irrespective of any amendment, modification or waiver of any term
of Senior Indebtedness or extension or renewal of Senior Indebtedness. 
 (a) (i) In the event the Company shall default in the
payment of any Senior Indebtedness when the same becomes due and payable, whether at maturity or on a date fixed for prepayment or by declaration or otherwise, then, unless and until such default shall have been cured or waived or shall have ceased
to exist, no direct or indirect payment (in cash, property or securities or by set-off or otherwise) shall be made or agreed to be made on account of the principal of, premium, if any, or interest on the Securities, or as a sinking fund for the
Securities, or in respect of any redemption, retirement, purchase or other acquisition of any of the Securities. 
 (ii) Upon
the happening of an event of default with respect to any Senior Indebtedness, permitting the holders thereof to accelerate the maturity thereof (other than under circumstances when the terms of subdivision (a)(i) are applicable), then, unless and
until such event of default shall have been cured or waived or shall have ceased to exist, no direct or indirect payment (in cash, property or securities or by set-off or otherwise) shall be made or agreed to be made on account of the principal of,
or premium, if any, or interest on the Securities, or as a sinking fund for the Securities, or in respect of any redemption, retirement, purchase or other acquisition of any of the Securities, during any period: 

  
 34 

     (A) of 90 days after written notice of such default shall have been
given to the Company by any holder of Senior Indebtedness; or 
     (B) in which any judicial proceeding
shall be pending in respect of such default and a notice of acceleration of the maturity of such Senior Indebtedness shall have been transmitted to the Company in respect of such default. 

(b) In the event of 
 (i) any insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment, composition or other similar proceeding relating to the Company, its creditors or its property, 

(ii) any proceeding for the liquidation, dissolution or other winding-up of the Company, voluntary or involuntary, whether or not
involving insolvency or bankruptcy proceedings, 
 (iii) any assignment by the Company for the benefit of creditors, or

 (iv) any other marshalling of the assets of the Company, 

all Senior Indebtedness (including any interest accruing after the commencement of such proceedings) shall first be paid in full before
any payment or distribution, whether in cash, securities or other property, shall be made to any Holder of Securities on account of the Securities. Any payment or distribution, whether in cash, securities or other property (other than securities of
the Company or any other corporation provided for by a plan of reorganization or readjustment the payment of which is subordinate, at least to the extent provided in this Article with respect to the Securities, to the payment of all Senior
Indebtedness at the time outstanding and to any securities issued in respect thereof under any such plan of reorganization or readjustment), which would otherwise (but for the provisions of this Article) be payable or deliverable in respect of the
Securities shall be paid or delivered directly to the holders of Senior Indebtedness in accordance with the priorities then existing among such holders until all Senior Indebtedness (including any interest thereon accruing after the commencement of
any such proceedings) shall have been paid in full. 
 (c) In the event that any Security shall be declared due and payable as
the result of the occurrence of any one or more defaults in respect thereof, under circumstances when the terms of subparagraph (b) are not applicable, no payment shall be made in respect of any Securities unless and until all Senior
Indebtedness shall have been paid in full or such declaration and its consequences shall have been rescinded and all such defaults shall have been remedied or waived. 
 (d) If any payment or distribution of any character or any security, whether in cash, securities or other property (other than securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to the extent provided in the provisions of this Article with respect to the Securities, to the payment of all Senior Indebtedness at the time outstanding and to any
securities issued in respect thereof under any such plan or reorganization or readjustment), shall be received by any Holder of Securities in contravention of any terms hereof and before all the Senior Indebtedness shall have been paid in full, such
payment or distribution or security shall be received in trust for the benefit of, and shall be paid over or delivered and transferred to, the holders of the Senior Indebtedness at the time outstanding, in accordance with the priorities then
existing among such holders for application to the payment of all Senior Indebtedness remaining unpaid, or, if applicable, to any trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company, to the extent necessary to pay all such Senior Indebtedness in full. In the event of the failure of any Holder of Securities to endorse or assign any such payment, distribution or security, each holder of
Senior Indebtedness is hereby irrevocably authorized to endorse or assign the same. 
 (e) Nothing contained herein shall
impair, as between the Company and the Holder of any Securities, the obligation of the Company to pay to the Holder thereof the principal thereof and interest thereon as and when the same shall become due and payable in accordance with the terms of
such Security, or prevent the Holder of any Securities from exercising all rights, powers and remedies otherwise permitted by applicable law or pursuant to the terms of this Indenture and the Security, upon a default or Event of Default under this
Indenture, all subject to the rights of the holders of the Senior Indebtedness to receive cash, securities or other property otherwise payable or deliverable to the Holders of the Securities. 

(f) Senior Indebtedness shall not be deemed to have been paid in full unless the holders thereof shall have received cash equal to the
amount of such Senior Indebtedness then outstanding. Upon the payment in full of all Senior Indebtedness, the Holders of Securities shall be subrogated to all rights of any holders of Senior Indebtedness to receive any further payments or
distributions applicable to the Senior Indebtedness until all amounts owing on the Securities shall have been paid in full, and such payments or distributions received by the holders of the Securities by reason of such subrogation, of cash,
securities or other property which otherwise would be paid or distributed to the holders of Senior Indebtedness, shall, as between the Company and its creditors other than the holders of Senior Indebtedness, on the one hand, and the Holders of
Securities, on the other hand, be deemed to be a payment by the Company on account of Senior Indebtedness and not on account of Securities. 

  
 35 

 The Company shall give prompt written notice to the Trustee of any insolvency, bankruptcy,
receivership, liquidation, reorganization, readjustment, composition or other similar proceeding relating to the Company within the meaning of this Section. Upon any payment or distribution of assets of the Company referred to in this Article, the
Trustee, subject to the provisions of Section 601, and the Holders of Securities shall be entitled to rely upon a certificate of the trustee in bankruptcy, receiver, assignee for the benefit of creditors or other liquidating agent making such
payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the person entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company,
the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. 
 In the event that the Trustee determines, in good faith, that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Section, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such person, as to the extent to which such person is
entitled to participate in such payment or distribution, and as to other facts pertinent to the rights of such person under this Section, and if such evidence is not furnished, the Trustee may defer any payment to such person pending judicial
determination as to the right of such person to receive such payment. 
 SECTION 1402.    Effectuation of Subordination by
Trustee. 
 Each Holder of Securities, by his acceptance thereof, authorizes and directs the Trustee in his behalf to take such
action as may be necessary or appropriate to effectuate, as between the Holders of the Securities and the holders of Senior Indebtedness, the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such
purposes. 
 SECTION 1403.    Knowledge of Trustee. 

Nothing contained in this Article or elsewhere in this Indenture, shall (a) prevent the Company from setting aside in trust or
depositing with the Trustee or any Paying Agent, at any time, except during the pendency of any of the proceedings or upon the happening or continuance of any of the events referred to in Section 1401, moneys for the payment of principal of, or
premium, if any, or interest on, the Securities, or (b) prevent the application by the Trustee or Paying Agent of any moneys deposited with it hereunder by or on behalf of the Company to the payment of or on account of the principal of, or the
premium, if any, or interest on the Securities, if the Trustee or the Paying Agent, as the case may be, did not have written notice of any event prohibiting such application by the close of business on the Business Day immediately prior to the date
of such application. 
 Notwithstanding the provisions of this Article or any other provisions of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any Senior Indebtedness or of any default or event of default with respect to any Senior Indebtedness or any fact or facts which would prohibit the making of any payment of moneys to or by the
Trustee, or the taking of any other action by the Trustee, unless and until the Trustee shall have received written notice thereof from the Company, any Holder of Securities, any paying or conversion agent of the Company or the holder or
representative of any class of Senior Indebtedness who shall have been certified by the Company or otherwise established to the reasonable satisfaction of the Trustee to be such holder or representative or by the trustee under any indenture pursuant
to which Senior Indebtedness shall be outstanding. 
 SECTION 1404.    Trustee’s Relation to Senior Indebtedness.

 The Trustee shall be entitled to all rights set forth in this Article with respect to any Senior Indebtedness at the time
held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in Section 612 or elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article shall subordinate to
Senior Indebtedness the claims of, or payments to, the Trustee under or pursuant to Section 607. 
 With respect to the
holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article and no implied covenants or obligations with respect to the holders of Senior
Indebtedness shall be read into this Indenture against the Trustee and the Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any holder of Senior Indebtedness if it shall pay over
or deliver to Holders, the Company or any other Person monies or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. 
 SECTION 1405.    Rights of Holders of Senior Indebtedness Not Impaired. 
 No right of any present or future holder of any Senior Indebtedness to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part
of the Company or by any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 

This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.
