 Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of the Outstanding Securities of all series or one
or more series, as the case may be, 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. The Trustee shall promptly deliver to the Company copies of all such instrument
or instruments delivered to the Trustee. 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 6.1) conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section. 
 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 or her the
execution thereof. Where such execution is by a signer acting in a capacity other than his or her individual capacity, such certificate or affidavit shall also constitute sufficient proof of his or her 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 that the Trustee deems sufficient. 
 The ownership, date of holding, principal amount and serial numbers of Securities shall be proved by the Security Register. 
 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 Company in reliance thereon, whether or not notation of such action is made upon such
Security. Any consent or waiver of the Holder of any Security shall be irrevocable for a period of six months after the date of execution thereof, but otherwise any such Holder or subsequent Holder may revoke the request, demand, authorization,
direction, notice, consent or other Act as to his Security or portion of his Security; provided, however, that such revocation shall be effective only if the Trustee receives the notice of revocation before the date the Act becomes effective.

 The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled
to give, make or take any request, demand, authorization, direction, vote, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company
may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no
such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be
construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Securities of the relevant series in the manner set forth in Section 1.7. 
  

 - 8 - 








 The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding
Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.2, (iii) any request to institute proceedings referred to in
Section 5.7(2) or (iv) any direction referred to in Section 5.12, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of
such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from
setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and
nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities
of the relevant series in the manner set forth in Section 1.7. 
 With respect to any record date set pursuant to this Section,
the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 1.7, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant to this Section 1.5, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the
Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard
to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. 
 Section 1.6 Notices, etc., to Trustee and Company. 
 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 (or by facsimile transmissions, provided that oral confirmation of receipt shall have been received) to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Department, 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 furnished by certified mail, return receipt requested, personally delivered or furnished via overnight courier to the Company addressed to it at the address of its principal office specified in the first paragraph of this
instrument or at any other address previously furnished in writing to the Trustee by the Company, Attention: Chief Financial Officer. 
 Section 1.7 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, or delivered by hand or overnight courier to each Holder affected by such event, at its address as it appears in the
Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. Neither the failure to mail or deliver by hand or overnight courier any notice, nor any defect in
any notice so mailed or delivered by hand or overnight courier, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 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 notice to Holders of Securities by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient 

  

 - 9 - 








 
notification for every purpose hereunder. In any case in which notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder of a Security, shall affect the sufficiency of such notice with respect to other Holders of Securities. 
 Section 1.8 Conflict with Trust Indenture Act. 
 If any provision hereof limits, qualifies or
conflicts with a provision of the Trust Indenture Act or another provision hereof required to be included in this Indenture by any of the provisions of the Trust Indenture Act, the latter 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 1.9 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 1.10 Successors and Assigns.

Company shall bind its successors and assigns, whether or not so expressed. All agreements of the Trustee in this Indenture shall bind its successor. 
 Section 1.11 Separability Clause.

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.

implied, shall give to any Person, other than the parties hereto and their successors hereunder, any Authenticating Agent, Paying Agent or Security Registrar, and the Holders, any benefit or any legal or equitable right, remedy or claim under this
Indenture.

Redemption Date, sinking fund payment date, or Stated Maturity or Maturity or other payment date of any Security or the last date on which a Holder has the right to convert a Security at a particular conversion price shall not be a Business Day at

principal (and premium, if any) or, if applicable to a particular series of Securities, conversion 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 or Redemption Date, at the Stated Maturity or on such last day for conversion, as the case may be.

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

 Section 2.3 Global Securities. 
 If the Company shall establish pursuant to Section 3.1 that the Securities of a particular 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 3.3 and the Company Order delivered to the Trustee thereunder, authenticate and deliver such Global Security or
Securities, which (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 such Global Security or Securities, (ii) may provide
that the aggregate amount of Outstanding Securities represented thereby may from time to time be increased or reduced to reflect exchanges, (iii) shall be registered in the name of the Depositary for such Global Security or Securities or its
nominee, (iv) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction and (v) shall bear a legend in accordance with the requirements of the Depositary. 
 Notwithstanding any other provision of this Section or of Section 3.5, except as contemplated by the provisions of this
Section 2.3 below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for individual Securities, a Global Security may be transferred, in whole but not in part and in the
manner provided in Section 3.5, only to a nominee of the Depositary for such Global Security, or to the Depositary, or to a successor Depositary for such Global Security selected or approved by the Company, or to a nominee of such
successor Depositary. 
 If at any time the Depositary for a Global Security notifies the Company that it is unwilling or unable to continue
as the Depositary for such Global Security or if at any time the Depositary for the Securities for such series shall no longer be eligible or in good standing under the Exchange Act, or other applicable statute or regulation, the Company shall
appoint a successor Depositary with respect to such Global Security. If a successor Depositary for such Global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of Securities of such series in the form of definitive certificates in exchange for such Global Security, will authenticate
and deliver Securities of such series in the form of definitive certificates of like tenor and terms in an aggregate principal amount equal to the principal amount of the Global Security in exchange for such Global Security. Such Securities will be
issued to and registered in the name of such Person or Persons as are specified by the Depositary. 
 The Company may at any time and in its
sole discretion determine that the Securities of any series issued or issuable in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In any such event the Company will execute, and the
Trustee, upon receipt of a Company Request for the authentication and delivery of Securities in the form of definitive certificates in exchange in whole or in part for such Global Security, will authenticate and deliver without service charge to
each Person specified by the Depositary Securities in the form of definitive certificates of like tenor and terms in an aggregate principal amount equal to the principal amount of such Global Security representing such series, or the aggregate
principal amount of such Global Securities representing such series, in exchange for such Global Security or Securities. 
 If specified by
the Company pursuant to Section 3.1 with respect to Securities issued or issuable in the form of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for Securities
in the form of definitive certificates of like tenor and terms 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 service charge,

Treasurer, its Secretary or one of its Assistant Treasurers or Assistant Secretaries. 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
Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and
deliver such Securities; provided, however, that in the case of Securities offered in a Periodic Offering, the Trustee shall authenticate and deliver such Securities from time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of oral or electronic instructions from the Company or its duly authorized agents, promptly confirmed in writing) acceptable to the Trustee as may be specified by or pursuant to a Company Order delivered to the
Trustee prior to the time of the first authentication of Securities of such series. Each Security shall be dated the date of its authentication unless otherwise provided by a Board Resolution, a supplemental indenture hereto or an Officers’
Certificate. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions or any other method permitted by Sections 2.1 and 3.1, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying upon, a copy of such Board
Resolution, the Officers’ Certificate setting forth the terms of the series and an Opinion of Counsel, with such Opinion of Counsel stating, 
  

 - 19 - 








 (1) if the form or terms of such Securities have been established by or pursuant to
Board Resolution or any other method permitted by Sections 2.1 and 3.1, that such form or terms have been, or in the case of Securities of a series offered in a Periodic Offering will be, established in conformity with the
provisions of this Indenture, subject in the case of Securities offered in a Periodic Offering, to any conditions specified in such Opinion of Counsel; and 
 (2) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions, exceptions and qualifications specified in such Opinion of Counsel,
will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, except as such enforcement is subject to the effect of (i) bankruptcy, insolvency, fraudulent conveyance, reorganization or other
laws relating to or affecting creditors’ rights and (ii) general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law). 
 Such Opinion of Counsel need express no opinion as to the enforceability of Section 6.7 or as to whether a court in the United States would
render a money judgment in a currency other than that of the United States. Notwithstanding the provisions of Section 3.1 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall
not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication
of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. 
 Notwithstanding that such form or terms have been so established, the Trustee shall have the right to decline to authenticate such Securities if, in the
written opinion of counsel to the Trustee (which counsel may be an employee of the Trustee), such action may not lawfully be taken or if the Trustee in good faith by its board of trustees or trustees, executive committee or a trust committee of
directors, trustees or vice presidents shall determine that such action would expose the Trustee to personal liability to Holders of any Securities then outstanding. 
 With respect to Securities of a series offered in a Periodic Offering, the Trustee may rely, as to the authorization by the Company of any of such Securities, the form and terms thereof and the legality, validity,
binding effect and enforceability thereof, upon the Opinion of Counsel and the other documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as applicable, in connection with the first authentication of Securities of such
series. 
 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. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 3.9, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture. 
 The Company in issuing Securities may use “CUSIP” numbers (if then generally in use), and if so,
the Trustee may use the CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in
the notice or on the Securities, that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption or exchange shall not be affected by any defect or omission of such CUSIP numbers. The Company
will promptly notify the Trustee of any change in CUSIP numbers known to an Officer of the Company. Neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Security, check, advice of
payment or redemption notice, and any such document may contain a statement to the effect that CUSIP numbers have been assigned by an independent service for convenience of reference and that neither the Company nor the Trustee shall be liable for
any inaccuracy in such numbers. 
 Section 3.4 Temporary Securities. 
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee 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. All or any portion of the temporary Securities of a series may be
Global Securities. 
  

 - 20 - 








 If temporary Securities of any series are issued, the Company will cause definitive Securities of that
series to be prepared without unreasonable delay. Except in the case of temporary Securities that are Global Securities, each of which shall be exchanged in accordance with the provisions thereof, after the preparation of definitive Securities of
such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. 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 and tenor, except as otherwise specified as contemplated by Section 3.1. 
 Section 3.5 Registration; Registration of Transfer and Exchange. 
 The Company shall cause to be kept at the Corporate
Trust Office of the Trustee or in any office or agency to be maintained by the Company in accordance with Section 9.2 in a Place of Payment or in such other place or medium as may be specified pursuant to Section 3.1 a
register for each series of Securities (each register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes 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 such series and of transfers of Securities of such series. Unless otherwise contemplated by Section 3.1, the Trustee is
hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities, and for the purpose of maintaining the Security Register in respect thereof, as herein provided. 
 Except as set forth in Section 2.3 or as may be provided pursuant to Section 3.1, upon surrender for registration of transfer of
any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute and deliver a Company Order requesting the Trustee to authenticate and deliver, and the Trustee 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 like tenor and aggregate principal amount. 
 Unless otherwise provided as contemplated by Section 3.1, at the option of the Holder, Securities of any series (other than Global
Securities) may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, 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 shall authenticate and deliver, the Securities that 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 for exchange shall (if so required by the Company, Security Registrar or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company, the Security Registrar or the Trustee, as the case may be, duly executed, by the Holder thereof or its attorney duly authorized in
writing. 
 Unless otherwise provided as contemplated by Section 3.1, 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 3.4, 9.6 or 11.7 not involving any transfer. 
 Unless otherwise provided as
contemplated by Section 3.1, if the Securities of any series (or of any series and specified tenor) are to be redeemed in whole or in part, the Company shall not be required (A) to issue, register the transfer of or exchange any
Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for
redemption under Section 11.3 and ending at the close of business on the day of such mailing, or (B) 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. 
  

 - 21 - 








 Unless otherwise provided as contemplated by Section 3.1, the Company shall not be required
to register the transfer or exchange of Securities between a Record Date and the next succeeding Interest Payment Date. 
 Section 3.6
Mutilated, Destroyed, Lost and Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee, the Company shall
execute and deliver a Company Order requesting the Trustee to authenticate and deliver, and the Trustee shall authenticate and deliver, in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, 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 the
Company’s request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously
outstanding. 
 Notwithstanding the preceding paragraph, 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 3.6, 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 3.6 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 3.6 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 3.7 Payment of Interest; Interest Rights Preserved. 
 Except as otherwise provided as contemplated by Section 3.1 with respect to any series of Securities, 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 at the office or agency maintained for such purpose
pursuant to Section 9.2; provided, however, that at the option of the Company, interest on any series of Registered Securities that bear interest may be paid (i) by check mailed to the address of the Person entitled thereto as it
shall appear on the Security Register of such series (unless, with respect to a Global Security, the rules of the Depositary require payment of such amount by wire transfer) or (ii) by wire transfer to an account maintained by the Person
entitled thereto as specified in the Security Register of such series. 
 Unless otherwise provided as contemplated by
Section 3.1, 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 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 

  

 - 22 - 








 
Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.7, not less than 10 days
prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper, but such publication shall not be a condition
precedent to the establishment of 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 3.7, 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 3.8 Persons Deemed Owners. 
 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.7) any interest and any Additional Amounts or other payments on
such Security and for all other purposes whatsoever, whether or not such Security shall be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 Except as otherwise specified as contemplated by Section 3.1, none of the Company, the Trustee or any agent of the Company or the Trustee
shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of 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 or 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 (or its nominee), 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 3.9
Cancellation. 
 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 may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the
Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. The Security Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer,
exchange or payment, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by
this Indenture or as otherwise specified as contemplated by Section 3.1. On request of the Company at the time of surrender, the Trustee shall deliver to the Company canceled Securities held by the Trustee. In the absence of such
request, all canceled Securities held by the Trustee shall be disposed of in accordance with the Trustee’s customary procedures. 
 Section 3.10 Computation of Interest. 
 Except as otherwise specified as contemplated by Section 3.1 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.

 ARTICLE 4 
 SATISFACTION AND DISCHARGE 
 Section 4.1 Satisfaction and Discharge of Indenture.

 This Indenture shall upon Company Request cease to be of further effect with respect to Securities of or within any series (except as to
any surviving rights of registration of transfer or exchange of such Securities and replacement of such Securities which may have been lost, stolen or mutilated as herein expressly provided for), and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to such Securities, when 
 (1) either 
 (A) all such Securities 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 3.6 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held
in trust by the Trustee or the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.3) have been delivered to the Trustee for cancellation; or 
 (B) all such Securities not theretofore delivered to the Trustee for cancellation 
 (i) have become due and payable, or 
 (ii) will become due and payable at their Stated Maturity within one year, or 
 (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the Company, in the case of clause (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds
in trust for the purpose money in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest and any Additional Amounts
to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Outstanding Securities of such series; 
 (3) the Company has complied with any other conditions specified pursuant to Section 3.1 to be applicable to the
Outstanding Securities of such series; and 
 (4) 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 this Indenture as to such Securities have been complied with. 
 If any Outstanding Securities of such 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 trust agreement evidencing the trust referred to in subclause (B) of clause (1) of this Section 4.1 shall provide therefore and 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. 
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.7, the obligations of the Trustee to any Authenticating Agent under
Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 4.1, the obligations of the Trustee under Section 4.2 and the
last paragraph of Section 10.3 shall survive. 
 Section 4.2 Application of Trust Money. 
 Subject to the provisions of the last paragraph of Section 10.3, all money deposited with the Trustee pursuant to Section 4.1
shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, 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 and any premium and interest or Additional Amounts for whose payment such money has been deposited with the Trustee. 
  

 - 24 - 








 Section 4.3 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations deposited with respect to Securities of any series in
accordance with Section 4.1 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations
under this Indenture with respect to the Securities of such series and the Securities of such series shall be revived and reinstated as though no deposit had occurred pursuant to Section 4.1 until such time as the Trustee or Paying Agent
is permitted to apply all such money or U.S. Government Obligations in accordance with Section 4.1; provided, however, that if the Company has made any payment of principal of, premium (if any) or interest on, or any Additional Amounts
with respect to, any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the
Trustee or Paying Agent. 
 ARTICLE 5 
 REMEDIES 
 Section 5.1 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 occasioned by the subordination provisions applicable to any Securities or 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), unless it is either inapplicable to a particular series or it is specifically deleted or modified in the Board Resolution, supplemental indenture, Officers’
Certificate establishing such series, or form of Security for such series: 
 (1) default in the payment of any interest
on, or any Additional Amounts with respect to, any Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of such payment is deposited by the Company with the
Trustee or with a Paying Agent prior to the expiration of such period of 30 days); or 
 (2) default in the payment
of the principal of or any premium 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, and continuance of such default for a period of 30 days; or 
 (4) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this
Section 5.1 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 60 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 entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable federal or state
bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or
in respect of the Company under any applicable federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering
the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or 
 (6) the commencement by the Company of a voluntary case or proceeding under any applicable federal or state bankruptcy, insolvency,
reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under
any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it, of a petition or answer or consent seeking
reorganization or relief under any applicable federal or state law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a 

  

 - 25 - 








 
custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making
by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action; or 

(7) any other Event of Default provided with respect to Securities of that series in the Board Resolution, supplemental indenture
or Officers’ Certificate establishing that series. 
 Notwithstanding the foregoing provisions of this Section 5.1, if the
principal of, premium (if any) or any interest on, or any Additional Amounts with respect to, any Security is payable in a currency or currencies (including a composite currency) other than Dollars and such currency or currencies are not available
to the Company for making payment thereof due to the imposition of exchange controls or other circumstances beyond the control of the Company (a “Conversion Event”), the Company will be entitled to satisfy its obligations to Holders
of the Securities by making such payment in Dollars in an amount equal to the Dollar equivalent of the amount payable in such other currency, as determined by the Company by reference to the Exchange Rate, as such Exchange Rate is certified for
customs purposes by the Federal Reserve Bank of New York on the date of such payment, or, if such rate is not then available, on the basis of the most recently available Exchange Rate. Notwithstanding the foregoing provisions of this
Section 5.1, any payment made under such circumstances in Dollars where the required payment is in a currency other than Dollars will not constitute an Event of Default under this Indenture. 
 Promptly after the occurrence of a Conversion Event with respect to the Securities of any series, the Company shall give written notice thereof to the
Trustee; and the Trustee, promptly after receipt of such notice, shall give notice thereof in the manner provided in Section 1.7 to the Holders of such series. Promptly after the making of any payment in Dollars as a result of a
Conversion Event with respect to the Securities of any series, the Company shall give notice in the manner provided in Section 1.7 to the Holders of such series, setting forth the applicable Exchange Rate and describing the calculation
of such payments. 
 Section 5.2 Acceleration of Maturity; Rescission and Annulment. 
 Unless the Board Resolution, supplemental indenture or Officers’ Certificate establishing such series provides otherwise, if an Event of Default
(other than an Event of Default specified in Section 5.1(5) or 5.1(6)) 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 of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal
amount of such Securities as may be specified by the terms thereof) and premium, if any, together with accrued and unpaid interest, if any, thereon, and Additional Amounts, if any, with respect thereto, to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal amount (or specified amount) and premium, if any, together with accrued and unpaid interest, if any, thereon, and Additional
Amounts, if any, with respect thereto, shall become immediately due and payable. Unless the Board Resolution, supplemental indenture or Officers’ Certificate establishing such series provides otherwise, if an Event of Default specified in
Section 5.1(5) or 5.1(6) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) and premium, if any, together with accrued and unpaid interest, if any, thereon, and Additional Amounts, if any, with respect thereto,
shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 
 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 5 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 on, and any Additional Amounts with respect to, all Securities of that series (or of all series, as the case
may be), 
 (B) the principal of or premium (if any) on any Securities of that series (or of all series, as the case may
be) which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities (in the case of Original Issue Discount Securities, the Securities’ Yield to
Maturity), 
  

 - 26 - 








 (C) to the extent that payment of such interest is lawful, interest upon overdue
interest and any Additional Amounts at the rate or rates prescribed therefor in such Securities (in the case of Original Issue Discount Securities, the Securities’ Yield to Maturity), and 
 (D) all sums paid or advanced by the Trustee hereunder, the compensation, expenses, disbursements and advances due to Trustee under
Section 6.7, and all other amounts due under Section 6.7; 
 (2) all Events of Default with
respect to Securities of that series (or of all series, as the case may be), other than the nonpayment of the principal of Securities of that series (or of all series, as the case may be) which have become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 5.13; and 
 (3) the rescission would not
conflict with any final judgment or decree of a court of competent jurisdiction. 
 No such rescission shall affect any subsequent default or
impair any right consequent thereon. 
 Section 5.3 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, or any Additional Amounts with respect to, any Security of any series when such interest or Additional Amounts shall become 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 at
the Maturity thereof, 
 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then
due and payable on such Securities for principal and any premium and interest on, and Additional Amounts with respect to, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium
and on any overdue interest or Additional Amounts, at the rate or rates prescribed therefor in such Securities (or in the case of Original Issue Discount Securities, the Securities’ Yield to Maturity), 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, and all other amounts due the Trustee under
Section 6.7. 
 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 deemed 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. 
 In addition, if any other Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed,
in its own name and as trustee of an express trust, 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 5.4 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 (or lesser amount in the case of Original Issue Discount Securities) of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal of, premium (if any), interest on, or any Additional Amounts with
respect to, such Securities) shall be entitled and empowered, by intervention in such proceeding or otherwise, 
 (1) to
file and prove a claim for the whole amount of principal (or lesser amount in the case of Original Issue Discount Securities) (and premium, if any) and interest and any Additional Amounts owing and unpaid in respect of the Securities and to file
such other papers or documents as may be necessary or advisable to have the claims of the Trustee (including any claim for the 

  

 - 27 - 








 
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding,
and 
 (2) to collect and receive any monies 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 6.7. 
 No provision of this Indenture 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; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

 Section 5.5 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 may be instituted by the Trustee in its own name as trustee of an express trust. 
 Section 5.6 Application of Money Collected. 
 Subject to the subordination provisions applicable to any series of Securities, any money collected by the Trustee pursuant to this Article shall be applied and paid 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 any premium or interest on, or any Additional Amounts with respect to, the Securities, 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 6.7 in connection with such series of Securities in respect of which money or other property is collected; 
 SECOND:
Subject to the terms of any subordination entered into as contemplated by Section 3.1, to the payment of the amounts then due and unpaid for principal of and any premium, if any, and interest on, and any Additional Amounts with respect
to, 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 any premium, if any,
interest on and Additional Amounts, respectively; and 
 THIRD: The balance, if any, to the Company or any other Person or Persons entitled
thereto. 
 To the fullest extent allowed under applicable law, if for the purpose of obtaining judgment against the Company in any court it
is necessary to convert the sum due in respect of the principal of, premium (if any) or interest on, or any Additional Amounts with respect to, the Securities of any series (the “Required Currency”) into a currency in which a
judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the
Judgment Currency on the Business Day in The City of New York next preceding that on which final judgment is given. Neither the Company nor the Trustee shall be liable for any shortfall nor shall any of them benefit from any windfall in payments to
Holders of Securities under this Section 5.6 caused by a change in exchange rates between the time the amount of a judgment against it is calculated as above and the time the Trustee converts the Judgment Currency into the Required
Currency to make payments under this Section 5.6 to Holders of Securities, but payment of such judgment shall discharge all amounts owed by the Company on the claim or claims underlying such judgment. 
 Section 5.7 Limitation on Suits. 
 Subject to Section 5.8, 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 
  

 - 28 - 








 (1) an Event of Default with respect to such series of Securities shall have
occurred and be continuing and such Holder has previously given written notice to the Trustee of such continuing Event of Default; 
 (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 and, if requested, provided 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 (or of all series, as the
case may be). 
 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 of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all of such Holders. 
 Section 5.8 Right of Holders to Receive Principal, Premium and
Interest. 
 Notwithstanding any other provision in this Indenture, the right of any Holder of any Security to receive payment of the
principal of and any premium and (subject to Section 3.7) interest on, or any Additional Amounts with respect to, such Security on the Stated Maturity or Stated 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 after the respective due dates, shall not be impaired without the consent of such Holder. 
 Section 5.9 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 5.10 Rights and Remedies Cumulative. 
 Except as otherwise provided in Section 5.7 or with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities
in the last paragraph of Section 3.6, 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 5.11 Delay or Omission Not
Waiver. 
 No delay or omission of the Trustee or of any Holder of any Securities 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 5 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 5.12
Control by Holders. 
 With respect to Securities of any series, the Holders of a majority in principal amount of the Outstanding
Securities of such 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, relating to or arising under an
Event of Default described in clause (1), (2), (3), (4) or (7) of Section 5.1, and with respect to all Securities the Holders of a majority in principal amount of all Outstanding Securities


  

 - 29 - 








 
shall have the right to direct the time, method and place of conducting any remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, relating to or arising under an Event of Default described in clause (5) or (6) of Section 5.1, provided that in each such case. 
 (1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, determines
that the action so directed may not lawfully be taken or would conflict with this Indenture or if the Trustee in good faith shall, by a Responsible Officer, determine that the proceedings so directed would involve it in personal liability or be
unjustly prejudicial to the Holders not taking part in such direction, and 
 (2) the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with such direction or this Indenture. 
 Section 5.13 Waiver of Past
Defaults. 
 Subject to Section 5.8 and Section 9.2, the Holders of not less than a majority in aggregate
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 or Event of Default described in clause (1), (2), (3), (4) or
(7) of Section 5.1 hereunder with respect to such series and its consequences, and the Holders of a majority in principal amount of all Outstanding Securities may on behalf of the Holders of all Securities waive any Event of
Default described in clause (5) or (6) of Section 5.1 hereunder and its consequences, except a default 
 (1) in the payment of the principal of or any premium or interest on, or any Additional Amounts with respect to, any Security as and when the same shall become due and payable by the terms thereof, otherwise than
by acceleration (unless such default has been cured as provided herein), or 
 (2) in respect of a covenant or provision
hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected. 
 Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon. 
 Section 5.14 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 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, a court may require any party litigant in such suit to file an undertaking to pay the costs of
such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that the provisions of this Section 5.14 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 interest on any Security on or after the Stated Maturity or Stated Maturities expressed in such Security (or, in the case of redemption, on the redemption date). 
 ARTICLE 6 
 THE TRUSTEE

 Section 6.1 Certain Duties and Responsibilities. 
 (1) If an Event of Default has occurred and is continuing, the Trustee shall exercise 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 individual would exercise or use under the circumstances in the conduct of his or her own affairs. 
 (2) Except during the continuance of an Event of Default: 
 (A) The Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied
covenants or obligations shall be read into this Indenture against the Trustee.

to the truth of the statements and the correctness of the opinions expressed therein, upon Officers’ Certificates or Opinions of Counsel furnished to the Trustee and conforming to the requirements of this Indenture; however, in the case of any
such Officers’ Certificates or Opinions of Counsel which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officers’ Certificates and Opinions of Counsel to determine whether
or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein). 
 (3) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful
misconduct or bad faith, except that: 
 (A) This paragraph does not limit the effect of clause (2) of this

Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts.

 (6) No provision of this Indenture shall require the Trustee to risk its own funds or otherwise incur any financial liability in the
performance of any of its duties, 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 is not reasonably assured to it. 

(7) The Paying Agent, the Security Registrar and any Authenticating Agent shall be entitled to the protections, immunities and
standard of care as are set forth in clauses (1), (2) and (3) of this Section 6.1 with respect to the Trustee. 
 Section 6.2 Notice of Defaults. 
 If a default occurs hereunder and is continuing with respect
to Securities of any series and it is known to a Responsible Officer of the Trustee, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust Indenture Act; provided, however,
that except in the case of a default in the payment of principal of (or premium, if any) or interest on, or any Additional Amounts with respect to, any Securities of such series or in the payment of any sinking fund installment, the Trustee shall be
protected in withholding such notice if and so long as the Board of Trustees, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the
interests of the holders of Securities of such series. 
 Section 6.3 Certain Rights of Trustee. 
 Subject to the provisions of Section 6.1:

debenture, note, coupon, 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; 
 (2) 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, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney;

or (2) written notice of such default or Event of Default shall have been given to the Trustee by the Company or any other obligor on such Securities or by any Holder of such Securities; and 
 (8) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized

 Section 6.4 Not Responsible for Recitals or
Issuance of Securities. 
 The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication,
shall be taken as the statements of the Company, and neither the Trustee nor any Security Registrar, Paying Agent or 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 Security Registrar, Paying Agent or Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof.

 Section 6.5 May Hold Securities and Act as Trustee under Other Indentures. 
 The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections 6.8 and 6.13, 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. 
 Subject to the limitations imposed by the Trust Indenture Act, nothing in this Indenture shall
prohibit the Trustee from becoming and acting as trustee under other indentures under which other securities, or certificates of interest of participation in other securities, of the Company are outstanding in the same manner as if it were not
Trustee hereunder. 
 Section 6.6 Money Held in Trust. 
 Subject to the provisions of Sections 10.3 and 13.5, all moneys received by the Trustee shall, until used or applied, as provided
herein, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be 

  

 - 32 - 








 
segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed in writing with the Company. So long as no Event of Default shall have occurred and be continuing, all interest allowed on any such moneys shall be paid by the Company from time to time upon a Company Order. 
 Section 6.7 Compensation and Reimbursement. 
 The Company shall pay to the Trustee from time to time such reasonable compensation for its services as the Company and the Trustee may agree in writing from time to time. The Trustee’s compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred by it in connection with the performance of its
duties under this Indenture, except any such expense, disbursement or advance as may be attributable to its negligence, willful misconduct or bad faith. Such expenses shall include the reasonable compensation and expenses of the Trustee’s
agents and counsel. 
 The Company shall indemnify the Trustee for, and hold it harmless against, any and all loss, liability, damage, claim
or expense (including attorneys’ fees and expenses, and including taxes other than taxes based upon, measured by or determined by the income of the Trustee), including without limitation the costs and expenses of defending itself against any
third-party claim (whether asserted by any Holder or any other Person (other than the Company to the extent of any claim brought by it against the Trustee that establishes a breach by the Trustee in the observance or performance of its duties under
this Indenture)), incurred by it without negligence, willful misconduct or bad faith arising out of or in connection with its acceptance or administration of the trust or trusts hereunder, including the performance of its duties or the exercise of
its powers hereunder. With respect to any such claim other than a claim brought by the Company, (i) the Trustee shall notify the Company promptly of any claim for which it may seek indemnity, (ii) the Company may at its option defend the
claim, in which event the Trustee shall cooperate in the defense and the Trustee may have one separate counsel and the Company shall pay the reasonable fees and expenses of such counsel and (iii) the Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld. This indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee. 
 To secure the Company’s payment obligations in this Section 6.7, the Trustee shall have a lien prior to the Securities of any series on
all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on, or any Additional Amounts with respect to, particular Securities of that series. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.1(5) or (6) occurs, the
expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
 The
provisions of this Section 6.7 and any lien arising hereunder shall survive the resignation or removal of the Trustee or the discharge of the Company’s obligations under this Indenture and the termination of this Indenture.

 Section 6.8 Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such conflicting interest or resign, to the extent and in the manner and
with the effect provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a
trustee under this Indenture with respect to Securities of more than one series or any other indenture. 
 Section 6.9 Eligibility;
Disqualification. 
 There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series
(which need not be the same Trustee for all series). A Trustee may be Trustee hereunder for Securities of one or more series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has (or if the
Trustee is a member of a bank holding company system, its bank holding company has) a combined capital and surplus of at least $50,000,000 and subject to supervision or examination by federal or state (or the District of Columbia) authority. If any
such Person or bank holding company publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section 6.9 and to the extent permitted
by the Trust Indenture Act, the combined capital and surplus of such Person or bank holding company 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 the Trustee
with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section 6.9, it shall resign immediately in the manner and with the effect hereinafter specified in this Article 6.

  

 - 33 - 








 The Indenture shall always have a Trustee who satisfies the requirements of Sections 310(a)(1),
310(a)(2) and 310(a)(5) of the Trust Indenture Act. 
 Section 6.10 Resignation and Removal; Appointment of
Successor. 
 No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11. 
 The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not
have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series. 
 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. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been
delivered to the removed Trustee within 30 days after the receipt of such notice of removal, the removed Trustee may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series. 
 If at any time: 
 (1) the Trustee shall fail to comply with Section 6.8 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 cease to be eligible under
Section 6.9 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
 (3) 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, (A) the Company by a Board Resolution
may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, 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. 
 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 such successor Trustee or Trustees shall comply with the applicable requirements of Section 6.11. 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 6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, the retiring Trustee may petition, or any Holder who has been a bona fide Holder of a Security of such series for
at least six months may petition, on behalf of himself and all others similarly situated, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 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 to all Holders of Securities of such series in the manner provided in Section 1.7. 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. 
  

 - 34 - 








 Section 6.11 Acceptance of Appointment by Successor. 
 In case of the appointment hereunder of a successor Trustee with respect to all 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, 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.

those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all 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 of 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 those series to which the appointment of such successor
Trustee relates.

certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to or acquiring all or substantially all the corporate trust business of the Trustee (including the administration of the trust created by this
Indenture), 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, or by succession to or acquisition of all or substantially all of the corporate
trust business of, such successor 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 6.14 Appointment of Authenticating Agent. 
 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 Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.6, and Securities so authenticated 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, except as other specified as contemplated by Section 3.1, shall at all times be a bank or trust company or corporation organized and doing business
under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having (or if the Authenticating Agent is a member of a bank holding company system, its bank
holding company has) a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State (or the 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 6.14, 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 6.14, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in this Section 6.14.  
 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 or acquiring 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 6.14, 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
for any series of Securities may resign at any time by giving written notice thereof to the Trustee for such series and to the Company. The Trustee for any series of Securities may at any time terminate the agency of an Authenticating Agent 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 for such series may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.7 to all Holders
of Securities of the series with respect to which such Authenticating Agent will serve. 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 6.14. 
 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 6.14,
and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.7. 
 If an
appointment with respect to one or more series is made pursuant to this Section 6.14, the Securities of such series may have endorsed thereon, in lieu of the Trustee’s certificate of authentication, an alternative certificate of
authentication in the following form: 
 This is one of the Securities of the series designated therein referred to in the within-mentioned
Indenture.

 Notwithstanding any provision of this Section 6.14 to the contrary, if at any time any
Authenticating Agent appointed hereunder with respect to any series of Securities shall not also be acting as the Security Registrar hereunder with respect to any series of Securities, then, in addition to all other duties of an Authenticating Agent
hereunder, such Authenticating Agent shall also be obligated: (i) to furnish to the Security Registrar promptly all information necessary to enable the Security Registrar to maintain at all times an accurate and current Security Register; and
(ii) prior to authenticating any Security denominated in a foreign currency, to ascertain from the Company the units of such foreign currency that are required to be determined by the Company pursuant to Section 3.2.

or agency. 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. Unless otherwise provided in a supplemental indenture or pursuant to Section 3.1 hereof, the Place of Payment for any series of Securities shall be the Corporate Trust Office of the Trustee. 
 The Company may also from time to time designate one or more other offices or agencies 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 other office or agency. 
 Section 10.3 Money for Securities Payments to be Held in Trust.

thereto a sum sufficient to pay the principal and any premium and interest, or any Additional Amounts, 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
prior to each due date of the principal of or any premium or interest on, or Additional Amounts with respect to, any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the
Trust Indenture Act, 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 for any series of Securities other than the Trustee 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 10.3, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the
Securities of that series.

with respect to one or more series of Securities, 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.

premium or interest on, or any Additional Amounts with respect to, any Security of any series and remaining unclaimed for a period ending on the earlier of the date that is ten Business Days prior to the date such money would escheat to the State or
two years after such principal, premium or interest or Additional Amount has become due and payable shall 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 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 an Authorized Newspaper in The Borough of Manhattan,
The City of New York and in such other Authorized Newspapers as the Trustee shall deem appropriate, notice that such money remains unclaimed and that, after a date specified herein, 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.

before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or upon the income, profits or property of the Company, and (2) all lawful claims for labor, materials and

(i) whose amount, applicability or validity is being contested in good faith by appropriate proceedings or (ii) if the failure to pay or discharge would not have a material adverse effect on the assets, business, operations, properties or
financial condition of the Company and its Subsidiaries, taken as a whole.

the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this
Section 10.10 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section 10.10 and express mention of the payment of Additional Amounts
(if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 
 If the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that
series will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at least 10 days prior to each date of payment of principal and any premium or interest if there has been any change
with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company shall furnish the Trustee and the Company’s principal Paying Agent or Paying Agents, if other than the Trustee, with an Officers’
Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any premium or interest on the Securities of that series shall be made to Holders of Securities of that series who are United States
Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the
amount, if any, required to be withheld on such payments to such Holders of Securities and the Company will pay to such Paying Agent the Additional Amounts required by this Section 10.10. The Company covenants to indemnify the Trustee
and any Paying Agent for, and to hold them harmless against any loss, liability or expense reasonably incurred without negligence, willful misconduct or bad faith on their part arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officers’ Certificate furnished pursuant to this Section 10.10. 
 ARTICLE 11 
 REDEMPTION OF SECURITIES 
 Section 11.1 Applicability of Article. 
 Securities of any series that are redeemable in whole or in part before their
Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.1 for such Securities) in accordance with this Article 11. 
 Section 11.2 Election to Redeem; Notice to Trustee. 
 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.1 for such Securities. In case of any redemption at
the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter
notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities (i) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (ii) pursuant to an election of the Company which is subject to a
condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction or condition. 
 Section 11.3 Selection by Trustee of Securities to Be Redeemed. 
 If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously
called for redemption, on a pro-rata basis, or in the Trustee’s discretion, by lot, or by such other method as the Trustee shall deem fair and appropriate, provided that the unredeemed portion of the principal amount of any Security shall be in
an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. 
 If any Security selected
for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for
redemption. 
  

 - 43 - 








 The Trustee shall promptly notify the Company and the Security Registrar in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, 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 Securities redeemed or to be redeemed only in part,
to the portion of the principal amount of such Securities which has been or is to be redeemed. 
 Section 11.4 Notice of
Redemption. 
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not fewer than 30 nor more than
90 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address appearing in the Security Register. 
 All notices of redemption shall state: 
 (1) the Redemption Date, 
 (2) the Redemption Price (including accrued interest, if
any, to be paid), 
 (3) if less than all the Outstanding Securities of any series consisting of more than a single
Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series
consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed, 
 (4) in case any Security is to be redeemed in part only, that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security 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, 
 (6) the place or places where each such Security is to be surrendered for payment of the Redemption Price, 
 (7) if applicable, the conversion price, the date on which the right to convert the principal of the Securities or the portions
thereof to be redeemed will terminate, and the place or places where such Securities may be surrendered for conversion, 
 (8) that the redemption is for a sinking fund, if such is the case, and 
 (9) the CUSIP number or numbers
and/or common codes of the Security being redeemed. 
 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, provided that the Company shall have prepared and provided to the Trustee the form of such notice, or, if acceptable to the
Trustee, provided sufficient information to enable the Trustee to prepare such notice, in each case on a timely basis. 
 Section 11.5
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 10.3) 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. 
 If any Security called for redemption is converted,
any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of any Holder of such Security to receive interest thereon) be paid to the Company on
Company Request, or if then held by the Company, shall be discharged from such trust. 
  

 - 44 - 








 Section 11.6 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 (and any Additional Amounts) to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest whose Stated Maturity is on or prior to the Redemption Date will 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 Record Dates according to their terms and the provisions of Section 3.7. 
 If any Security called
for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security or, in the case of Original Issue
Discount Securities, the Securities’ Yield to Maturity. 
 Section 11.7 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 its 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 and Stated Maturity and of like tenor, 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. 
 Unless otherwise specified as
contemplated by Section 3.1, the Company and any Affiliate of the Company may at any time purchase or otherwise acquire Securities in the open market or by private agreement. Such acquisition shall not operate as or be deemed for any
purpose to be a redemption of the indebtedness represented by such Securities. Any Securities purchased or acquired by the Company may be delivered to the Trustee and, upon such delivery, the indebtedness represented thereby shall be deemed to be
satisfied. Section 3. 9 shall apply to all Securities so delivered.

Applicability of Article. 
 The provisions of this Article 12 shall be applicable to any sinking fund for the retirement
of Securities of any series except as otherwise specified as contemplated by Section 3.1 for such Securities. 
 The minimum
amount of any sinking fund payment provided for by the terms of any Securities 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 such
Securities is herein referred to as an “optional sinking fund payment.” Unless otherwise provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in
Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the terms of such Securities. 
 Section 12.2 Satisfaction of Sinking Fund Payments with Securities. 
 The Company (1) may
deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such
Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series
required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited
shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be
reduced accordingly.

 Section 12.3 Redemption of Securities for Sinking Fund. 
 Not fewer than 45 days prior (unless a shorter period shall be satisfactory to the Trustee) to each sinking fund payment date for any Securities,
the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, 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 pursuant to Section 12.2 and will also deliver to the Trustee any Securities to be so delivered. Not fewer than
30 days prior to 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 11.3 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 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in

 The Company may elect, at its option at any time, to have Section 13.2 or Section 13.3
applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 3.1 as being defeasible pursuant to such Section 13.2 or 13.3, in accordance with any applicable requirements

 Section 13.2 Defeasance and Discharge. 
 Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be,
the Company shall be deemed to have been discharged from its obligations with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 13.4 are satisfied (hereinafter called
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: 
 (1) the rights of Holders of such Securities to receive, solely from the trust fund described
in Section 13.4 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on, or any Additional Amounts with respect to, such Securities when payments are due, 
 (2) the Company’s obligations with respect to such Securities under Sections 3.4, 3.5, 3.6, 10.2 and 10.3,

10.5, 10.6, 10.7 or 10.8 and any covenants provided pursuant to Sections 3.1(22) or 9.1(2) for the benefit of the Holders of such Securities and

 (2) the occurrence of any event specified in Section 5.1(4) (with
respect to any of Sections 8.1, 10.4, 10.5, 10.6, 10.7 or 10.8 and any such covenants provided pursuant to Sections 3.1(22) or 9.1(2)) and the occurrence of any other Event of Default
specified pursuant to Section 3.1 or Section 9.1(3) shall be deemed not to be or result in an Event of Default, in each case with respect to such Securities or any series of Securities as provided in this
Section 13.3 on and after the date the conditions set forth in Section 13.4 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to
such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section or such other covenant (to the extent so specified in the case of
Section 5.1(4) and the occurrence of any Event of Default specified pursuant to Section 3.1 or Section 9.1(3)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or
such other covenant or by reason of any reference in any such Section or such other covenant to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby. 
 Section 13.4 Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the conditions to the application of Section 13.2 or Section 13.3 to any Securities or any series of Securities, as the case may be:

payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, an amount in cash, or 
 (iii) a combination thereof, 
 in each
case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such
other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. 
 (2) For Securities denominated in United States dollars, in the event of an election to have Section 13.2 apply to any
Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that

 (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, 
 in either
case clause (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit,
Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to
occur. 
  

 - 47 - 








 (3) For Securities denominated in United States dollars, in the event of an election
to have Section 13.3 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain
or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would
be the case if such deposit and Covenant Defeasance were not to occur. 
 (4) The Company shall have delivered to the
Trustee an Officers’ Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 
 (5) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities or
any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 5.1(5) and (6), at any time on or prior to the 90th day after the date of such deposit (it
being understood that this condition shall not be deemed satisfied until after such 90th day).

Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 
 (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this
Indenture or any other agreement or instrument to which the Company is a party or by which it is bound. 
 (8) Such
Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from
registration thereunder. 
 (9) The Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
 Section 13.5 Deposited Money, U. S. Government Obligations and Foreign Government Obligations to be Held in Trust; Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 10.3, all money, U.S. Government Obligations and Foreign Government Obligations (including the proceeds thereof) deposited with the Trustee or
other qualifying trustee (solely for purposes of this Section 13.5 and Section 13.6, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 13.4
in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting
as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other
funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations or Foreign Government Obligations deposited pursuant to
Section 13.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities. Anything in this Article 13 to the
contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money, U.S. Government Obligations or Foreign Government Obligations held by it as provided in Section 13.4 with respect
to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities. 
 Section 13.6
Reinstatement. 
 If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article 13 with
respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the
Company has been discharged or released pursuant to Section 13.2 or 13.3 shall be revived and reinstated as though no deposit had occurred pursuant to this Article 13 with respect to such Securities, until such time as
the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 13.5 with respect to such Securities in accordance with this Article 13; provided, however, that if the Company makes any payment
of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held
in trust.
