THE SECURITIES 

Section 2.01. Form and Dating. The Securities of each series shall be substantially in such form or forms (not inconsistent with
this Indenture) as shall be established by or pursuant to one or more Board Resolutions or in one or more indentures supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Indenture, as may be required to comply with any law, or with any rules of any
securities exchange or usage, all as may be determined by the Officers executing such Securities as evidenced by their execution of the Securities. Unless otherwise so established, Unregistered Securities shall have coupons attached. 

  
 8 













 Section 2.02. Execution and Authentication. Two Officers shall execute the
Securities and one Officer shall execute the coupons appertaining thereto for the Company by facsimile or manual signature in the name and on behalf of the Company. The seal of the Company, if any, shall be reproduced on the Securities. If an
Officer whose signature is on a Security or coupon appertaining thereto no longer holds that office at the time the Security is authenticated, the Security and such coupon shall nevertheless be valid. 

The Trustee, at the expense of the Company, may appoint an authenticating agent (the “Authenticating Agent”) to authenticate
Securities. The Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. 

A Security and the coupons appertaining thereto shall not be valid until the Trustee or Authenticating Agent manually signs the certificate of
authentication on the Security or on the Security to which such coupon appertains by an authorized officer. The signature shall be conclusive evidence that the Security or the Security to which the coupon appertains has been authenticated under this
Indenture. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of
any series having attached thereto appropriate coupons, if any, executed by the Company to the Trustee for authentication together with the applicable documents referred to below in this Section, and the Trustee shall thereupon authenticate and
deliver such Securities to or upon the written order of the Company. In authenticating any Securities of a series, the Trustee shall be entitled to receive prior to the authentication of any Securities of such series, and (subject to Article 7)
shall be fully protected in relying upon, unless and until such documents have been superseded or revoked: 
 (a) any Board Resolution and/or
executed supplemental indenture referred to in Sections 2.01 and 2.03 by or pursuant to which the forms and terms of the Securities of that series were established; 

(b) an Officer’s Certificate setting forth the form or forms and terms of the Securities, stating that the form or forms and terms of the
Securities of such series have been, or, in the case of a Periodic Offering, will be when established in accordance with such procedures as shall be referred to therein, established in compliance with this Indenture; and 

(c) an Opinion of Counsel substantially to the effect that the form or forms and terms of the Securities of such series have been, or, in the
case of a Periodic Offering, will be when established in accordance with such procedures as shall be referred to therein, established in compliance with this Indenture and that the supplemental indenture, to the extent applicable, and Securities
have been duly authorized and, if executed and authenticated in accordance with the provisions of the Indenture and delivered to and duly paid for by the purchasers thereof on the date of such opinion, would be entitled to the benefits of the
Indenture and would be valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, subject to bankruptcy, insolvency, reorganization, receivership, moratorium and other similar laws
affecting creditors’ rights generally, general principles of equity, and covering such other matters as shall be specified therein and as shall be reasonably requested by the Trustee. 

  
 9 













 The Trustee shall not be required to authenticate such Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 

Notwithstanding the provisions of Sections 2.01 and 2.02, if, in connection with a Periodic Offering, all Securities of a series are not
to be originally issued at one time, it shall not be necessary to deliver the Board Resolution otherwise required pursuant to Section 2.01 or the written order, Officer’s Certificate and Opinion of Counsel otherwise required pursuant to
Section 2.02 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. 

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 forms 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 2.01 and 2.02, as applicable, in connection
with the first authentication of Securities of such series. 
 If the Company shall establish pursuant to Section 2.03 that the
Securities of a series or a portion thereof are to be issued in the form of one or more Registered Global Securities, then the Company shall execute and the Trustee shall authenticate and deliver one or more Registered Global Securities that
(i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of all of the Securities of such series issued in such form and not yet cancelled, (ii) shall be registered in the name of the Depositary for
such Registered Global Security or Securities or the nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or its custodian or pursuant to such Depositary’s instructions and (iv) shall bear a legend
substantially to the following effect: “Unless and until it is exchanged in whole or in part for Securities in definitive registered form, this Security may not be transferred except as a whole by the Depositary to the nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.” 

Section 2.03. Amount Unlimited; Issuable in Series. The aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is unlimited. 

  
 10 













 The Securities may be issued in one or more series and shall be subordinated to the Senior
Indebtedness pursuant to the provisions of Article 11 hereof. There shall be established in or pursuant to Board Resolution or one or more indentures supplemental hereto, prior to the initial issuance of Securities of any series, subject to the
last sentence of this Section 2.03: 
 (a) the designation of the Securities of the series, which shall distinguish the Securities of
the series from the Securities of all other series; 
 (b) any limit upon the aggregate principal amount of the Securities of the series that
may be authenticated and delivered under this Indenture and any limitation on the ability of the Company to increase such aggregate principal amount after the initial issuance of the Securities of that series (except for Securities authenticated and
delivered upon registration of transfer of, or in exchange for, or in lieu of, or upon redemption of, other Securities of the series pursuant hereto); 

(c) the date or dates on which the principal of the Securities of the series is payable (which date or dates may be fixed or extendible); 

(d) the rate or rates (which may be fixed or variable) per annum at which the Securities of the series shall bear interest, if any, the date or
dates from which such interest shall accrue, on which such interest shall be payable and (in the case of Registered Securities) on which a record shall be taken for the determination of Holders to whom interest is payable and/or the method by which
such rate or rates or date or dates shall be determined; 
 (e) if other than as provided in Section 4.02, the place or places where the
principal of and any interest on Securities of the series shall be payable, any Registered Securities of the series may be surrendered for exchange, notices, demands to or upon the Company in respect of the Securities of the series and this
Indenture may be served and notice to Holders may be published; 
 (f) the right, if any, of the Company to redeem Securities of the series,
in whole or in part, at its option and the period or periods within which, the price or prices at which and any terms and conditions upon which Securities of the series may be so redeemed, pursuant to any sinking fund or otherwise; 

(g) the obligation, if any, of the Company to redeem, purchase or repay Securities of the series pursuant to any mandatory redemption, sinking
fund or analogous provisions or at the option of a Holder thereof and the price or prices at which and the period or periods within which and any of the terms and conditions upon which Securities of the series shall be redeemed, purchased or repaid,
in whole or in part, pursuant to such obligation; 
 (h) if other than denominations of $1,000 and any integral multiple thereof, the
denominations in which Securities of the series shall be issuable; 
 (i) if other than the principal amount thereof, the portion of the
principal amount of Securities of the series which shall be payable upon declaration of acceleration of the maturity thereof; 
 (j) if other
than the coin or currency in which the Securities of the series are denominated, the coin or currency in which payment of the principal of or interest on the Securities of the series shall be payable or if the amount of payments of principal of
and/or interest on the Securities of the series may be determined with reference to an index based on a coin or currency other than that in which the Securities of the series are denominated, the manner in which such amounts shall be determined;


  
 11 













 (k) if other than the currency of the United States of America, the currency or
currencies, including composite currencies, in which payment of the Principal of and interest on the Securities of the series shall be payable, and the manner in which any such currencies shall be valued against other currencies in which any other
Securities shall be payable; 
 (l) whether the Securities of the series or any portion thereof will be issuable as Registered Securities
(and if so, whether such Securities will be issuable as Registered Global Securities) or Unregistered Securities (with or without coupons) (and if so, whether such Securities will be issued in temporary or permanent global form), or any combination
of the foregoing, any restrictions applicable to the offer, sale or delivery of Unregistered Securities or the payment of interest thereon and, if other than as provided herein, the terms upon which Unregistered Securities of any series may be
exchanged for Registered Securities of such series and vice versa; 
 (m) whether the Securities of the series may be exchangeable for and/or
convertible into the common stock of the Company or any other security; 
 (n) whether and under what circumstances the Company will pay
additional amounts on the Securities of the series held by a person who is not a U.S. person in respect of any tax, assessment or governmental charge withheld or deducted and, if so, whether the Company will have the option to redeem such
Securities rather than pay such additional amounts; 
 (o) if the Securities of the series are to be issuable in definitive form (whether
upon original issue or upon exchange of a temporary Security of such series) only upon receipt of certain certificates or other documents or satisfaction of other conditions, the form and terms of such certificates, documents or conditions; 

(p) any trustees, depositaries, authenticating or paying agents, transfer agents or the registrar or any other agents with respect to the
Securities of the series; 
 (q) provisions, if any, for the defeasance of the Securities of the series (including provisions permitting
defeasance of less than all Securities of the series), which provisions may be in addition to, in substitution for, or in modification of (or any combination of the foregoing) the provisions of Article 8; 

(r) if the Securities of the series are issuable in whole or in part as one or more Registered Global Securities or Unregistered Securities in
global form, the identity of the Depositary or common Depositary for such Registered Global Security or Securities or Unregistered Securities in global form; 

(s) any other Events of Default or covenants with respect to the Securities of the series; and 

  
 12 













 (t) any other terms of the Securities of the series (which terms shall not be inconsistent
with the provisions of this Indenture). 
 All Securities of any one series and coupons, if any, appertaining thereto shall be substantially
identical, except in the case of Registered Securities as to date and denomination, except in the case of any Periodic Offering and except as may otherwise be provided by or pursuant to the Board Resolution referred to above or as set forth in any
such indenture supplemental hereto. All Securities of any one series need not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to such Board Resolution or in
any such indenture supplemental hereto and any forms and terms of Securities to be issued from time to time may be completed and established from time to time prior to the issuance thereof by procedures described in such Board Resolution or
supplemental indenture. 
 Unless otherwise expressly provided with respect to a series of Securities, the aggregate principal amount of a
series of Securities may be increased and additional Securities of such series may be issued up to the maximum aggregate principal amount authorized with respect to such series as increased. 

Section 2.04. Denomination and Date of Securities; Payments of Interest. The Securities of each series shall be issuable as
Registered Securities or Unregistered Securities in denominations established as contemplated by Section 2.03 or, if not so established with respect to Securities of any series, in denominations of $1,000 and any integral multiple thereof. The
Securities of each series shall be numbered, lettered or otherwise distinguished in such manner or in accordance with such plan as the Officers of the Company executing the same may determine, as evidenced by their execution thereof. 

Unless otherwise specified with respect to a series of Securities, each Security shall be dated the date of its authentication. The Securities
of each series shall bear interest, if any, from the date, and such interest and shall be payable on the dates, established as contemplated by Section 2.03. 

The person in whose name any Registered Security of any series is registered at the close of business on any record date applicable to a
particular series with respect to any interest payment date for such series shall be entitled to receive the interest, if any, payable on such interest payment date notwithstanding any transfer or exchange of such Registered Security subsequent to
the record date and prior to such interest payment date, except if and to the extent the Company shall default in the payment of the interest due on such interest payment date for such series, in which case the provisions of Section 2.13 shall
apply. The term “record date” as used with respect to any interest payment date (except a date for payment of defaulted interest) for the Securities of any series shall mean the date specified as such in the terms of the Registered
Securities of such series established as contemplated by Section 2.03, or, if no such date is so established, the fifteenth day next preceding such interest payment date, whether or not such record date is a Business Day. 

  
 13 













 Section 2.05. Registrar and Paying Agent; Agents Generally. The Company shall
maintain an office or agency where Securities may be presented for registration, registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying
Agent”), which shall be in the Borough of Manhattan, The City of New York. The Company shall cause the Registrar to keep a register of the Registered Securities and of their registration, transfer and exchange (the “Security
Register”). The Company may have one or more additional Paying Agents or transfer agents with respect to any series. 
 The Company
shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture and the Trust Indenture Act that relate to such Agent. The Company shall give prompt
written notice to the Trustee of the name and address of any Agent and any change in the name or address of an Agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such. The Company may remove any Agent upon
written notice to such Agent and the Trustee; provided that no such removal shall become effective until (i) the acceptance of an appointment by a successor Agent to such Agent as evidenced by an appropriate agency agreement entered into
by the Company and such successor Agent and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as such Agent until the appointment of a successor Agent in accordance with clause (i) of this
proviso. The Company or any affiliate of the Company may act as Paying Agent or Registrar; provided that neither the Company nor an affiliate of the Company shall act as Paying Agent in connection with the defeasance of the Securities or the
discharge of this Indenture under Article 8. 
 The Company initially appoints the Trustee as Registrar, Paying Agent and
Authenticating Agent. If, at any time, the Trustee is not the Registrar, the Registrar shall make available to the Trustee ten days prior to each interest payment date and at such other times as the Trustee may reasonably request the names and
addresses of the Holders as they appear in the Security Register. 
 Section 2.06. Paying Agent to Hold Money in Trust. Not
later than 10:00 a.m. New York City time on each due date or, in the case of Unregistered Securities, 10:00 a.m. New York City time on the Business Day prior to the due date, of any Principal or interest on any Securities, the
Company shall deposit with the Paying Agent money in immediately available funds sufficient to pay such Principal or interest. The Company shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold
in trust for the benefit of the Holders of such Securities or the Trustee all money held by the Paying Agent for the payment of Principal of and interest on such Securities and shall promptly notify the Trustee of any default by the Company in
making any such payment. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written
request to a Paying Agent, require such Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent shall have no further liability for the money so paid over to the Trustee. If the
Company or any affiliate of the Company acts as Paying Agent, it will, on or before each due date of any Principal of or interest on any Securities, segregate and hold in a separate trust fund for the benefit of the Holders thereof a sum of money
sufficient to pay such Principal or interest so becoming due until such sum of money shall be paid to such Holders or otherwise disposed of as provided in this Indenture, and will promptly notify the Trustee in writing of its action or failure to
act as required by this Section. 

  
 14 













 Section 2.07. Transfer and Exchange. Unregistered Securities (except for any
temporary global Unregistered Securities) and coupons (except for coupons attached to any temporary global Unregistered Securities) shall be transferable by delivery. 

At the option of the Holder thereof, Registered Securities of any series (other than a Registered Global Security, except as set forth below)
may be exchanged for a Registered Security or Registered Securities of such series and tenor having authorized denominations and an equal aggregate principal amount, upon surrender of such Registered Securities to be exchanged at the agency of the
Company that shall be maintained for such purpose in accordance with Section 2.05 and upon payment, if the Company shall so require, of the charges hereinafter provided. If the Securities of any series are issued in both registered and
unregistered form, except as otherwise established pursuant to Section 2.03, at the option of the Holder thereof, Unregistered Securities of any series may be exchanged for Registered Securities of such series and tenor having authorized
denominations and an equal aggregate principal amount, upon surrender of such Unregistered Securities to be exchanged at the agency of the Company that shall be maintained for such purpose in accordance with Section 4.02, with, in the case of
Unregistered Securities that have coupons attached, all unmatured coupons and all matured coupons in default thereto appertaining, and upon payment, if the Company shall so require, of the charges hereinafter provided. At the option of the Holder
thereof, if Unregistered Securities of any series, maturity date, interest rate and original issue date are issued in more than one authorized denomination, except as otherwise established pursuant to Section 2.03, such Unregistered Securities
may be exchanged for Unregistered Securities of such series and tenor having authorized denominations and an equal aggregate principal amount, upon surrender of such Unregistered Securities to be exchanged at the agency of the Company that shall be
maintained for such purpose in accordance with Section 4.02, with, in the case of Unregistered Securities that have coupons attached, all unmatured coupons and all matured coupons in default thereto appertaining, and upon payment, if the
Company shall so require, of the charges hereinafter provided. Registered Securities of any series may not be exchanged for Unregistered Securities of such series. Whenever any Securities are so surrendered for exchange, the Company shall execute,
and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 Upon
surrender for registration of transfer of any Registered Security of a series at the agency of the Company that shall be maintained for that purpose in accordance with Section 2.05 and upon payment, if the Company shall so require, of the
charges hereinafter provided, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized
denominations and of like tenor and aggregate principal amount. 
 All Registered Securities presented for registration of transfer,
exchange, redemption or payment shall be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Trustee duly executed by, the holder or his attorney duly authorized in
writing. 

  
 15 













 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 exchange or registration of transfer of Securities. No service charge shall be made for any such transaction. 

Notwithstanding any other provision of this Section 2.07, unless and until it is exchanged in whole or in part for Securities in
definitive registered form, a Registered Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. 

If at any time the Depositary for any Registered Global Securities of any series notifies the Company that it is unwilling or unable to
continue as Depositary for such Registered Global Securities or if at any time the Depositary for such Registered Global Securities shall no longer be eligible under applicable law, the Company shall appoint a successor Depositary eligible under
applicable law with respect to such Registered Global Securities. If a successor Depositary eligible under applicable law for such Registered Global Securities 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 the Company’s order for the authentication and delivery of definitive Registered Securities of such series and tenor, will authenticate
and deliver Registered Securities of such series and tenor, in any authorized denominations, in an aggregate principal amount equal to the principal amount of such Registered Global Securities, in exchange for such Registered Global Securities. 

The Company may at any time and in its sole discretion and subject to the procedures of the Depositary determine that any Registered Global
Securities of any series shall no longer be maintained in global form. In such event the Company will execute, and the Trustee, upon receipt of the Company’s order for the authentication and delivery of definitive Registered Securities of such
series and tenor, will authenticate and deliver, Registered Securities of such series and tenor in any authorized denominations, in an aggregate principal amount equal to the principal amount of such Registered Global Securities, in exchange for
such Registered Global Securities. 
 Any time the Registered Securities of any series are not in the form of Registered Global Securities
pursuant to the preceding two paragraphs, the Company agrees to supply the Trustee with a reasonable supply of certificated Registered Securities without the legend required by Section 2.02 and the Trustee agrees to hold such Registered
Securities in safekeeping until authenticated and delivered pursuant to the terms of this Indenture. 
 If established by the Company
pursuant to Section 2.03 with respect to any Registered Global Security, the Depositary for such Registered Global Security may surrender such Registered Global Security in exchange in whole or in part for Registered Securities of the same
series and tenor in definitive registered form on such terms as are acceptable to the Company and such Depositary. Thereupon, the Company shall execute, and the Trustee shall authenticate and deliver, without service charge: 

  
 16 













 (a) to the Person specified by such Depositary new Registered Securities of the same series
and tenor, of any authorized denominations as requested by such Person, in an aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Registered Global Security; and 

(b) to such Depositary a new Registered Global Security in a denomination equal to the difference, if any, between the principal amount of the
surrendered Registered Global Security and the aggregate principal amount of Registered Securities authenticated and delivered pursuant to clause (a) above. 

Registered Securities issued in exchange for a Registered Global Security pursuant to this Section 2.07 shall be registered in such names
and in such authorized denominations as the Depositary for such Registered Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee or an agent of the Company or the Trustee. The
Trustee or such agent shall deliver such Securities to or as directed by the Persons in whose names such Securities are so registered. 

All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
 Notwithstanding
anything herein or in the forms or terms of any Securities to the contrary, none of the Company, the Trustee or any agent of the Company or the Trustee shall be required to exchange any Unregistered Security for a Registered Security if such
exchange would result in adverse U.S. federal income tax consequences to the Company (such as, for example, the inability of the Company to deduct from its income, as computed for U.S. federal income tax purposes, the interest payable on
the Unregistered Securities) under then applicable U.S. federal income tax laws. The Trustee and any such agent shall be entitled to rely on an Officer’s Certificate or an Opinion of Counsel in determining such result. 

The Registrar shall not be required (i) to issue, authenticate, register the transfer of or exchange Securities of any series for a
period of 15 days before a selection of such Securities to be redeemed or (ii) to register the transfer of or exchange any Security selected for redemption in whole or in part. 

Section 2.08. Replacement Securities. If any mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver, in exchange for such mutilated Security or in exchange for the Security to which a mutilated coupon appertains, a new Security of the same series
and of like tenor and principal amount and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to such mutilated Security or to the Security to which such mutilated coupon appertains.

 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 or coupon and (ii) such security or indemnity as may be required by them to save each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Trustee that such Security or


  
 17 













 
coupon has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in exchange
for the Security to which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains. 

In case any such mutilated, destroyed, lost or stolen Security or coupon 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 or coupon (without surrender thereof except in the case of a mutilated Security or coupon) if the applicant for such payment shall furnish to the Company and the Trustee such
security or indemnity as may be required by them to save each of them and any agent of any of them harmless, and in the case of destruction, loss or theft, evidence satisfactory to the Company and the Trustee and any agent of them of the
destruction, loss or theft of such Security and the ownership thereof; provided, however, that the Principal of and any interest on Unregistered Securities shall, except as otherwise provided in Section 4.02, be payable only at an
office or agency located outside the United States of America. 
 Upon the issuance of any new Security under this Section, the Company
may require 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, with its coupons, if any, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security
or in exchange for any mutilated Security, or in exchange for a Security to which a mutilated, destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security and its coupons, if any, or the mutilated, destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and any such new Security and coupons, if any, shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that series and their coupons, if any, duly issued hereunder. 

The provisions of this Section are exclusive and shall preclude (to the extent lawful) any other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons. 
 Section 2.09. Outstanding Securities.
Securities outstanding at any time are all Securities that have been authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those described in this Section as not outstanding and those that have been
defeased pursuant to Section 8.05. 
 If a Security is replaced pursuant to Section 2.08, it ceases to be outstanding unless and
until the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a holder in due course. 

  
 18 













 If the Paying Agent (other than the Company or an affiliate of the Company) holds on the
maturity date or any redemption date or date for repurchase of the Securities money sufficient to pay Securities payable or to be redeemed or repurchased on that date, then on and after that date such Securities cease to be outstanding and interest
on them shall cease to accrue. 
 A Security does not cease to be outstanding because the Company or one of its affiliates holds such
Security, provided, however, that, in determining whether the Holders of the requisite principal amount of the outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder,
Securities owned by the Company or any affiliate of the Company shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Securities as to which a Responsible Officer of the Trustee has received written notice to be so owned shall be so disregarded. Any Securities so owned which are pledged by the Company, or by any affiliate
of the Company, as security for loans or other obligations, otherwise than to another such affiliate of the Company, shall be deemed to be outstanding, if the pledgee is entitled pursuant to the terms of its pledge agreement and is free to exercise
in its or his discretion the right to vote such securities, uncontrolled by the Company or by any such affiliate. 
 Section 2.10.
Temporary Securities. Until definitive Securities of any series are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities of such series. Temporary Securities of any series shall be substantially
in the form of definitive Securities of such series but may have insertions, substitutions, omissions and other variations determined to be appropriate by the Officers executing the temporary Securities, as evidenced by their execution of such
temporary Securities. If temporary Securities of any series are issued, the Company will cause definitive Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Securities of any series, the
temporary Securities of such series shall be exchangeable for definitive Securities of such series and tenor upon surrender of such temporary Securities at the office or agency of the Company designated for such purpose pursuant to
Section 4.02, 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 a like principal
amount of definitive Securities of such series and tenor and authorized denominations. Until so exchanged, the temporary Securities of any series shall be entitled to the same benefits under this Indenture as definitive Securities of such series.

 Section 2.11. Cancellation. The Company at any time may 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 for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold. The
Registrar, any transfer agent and the Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee shall cancel and dispose of in accordance with its customary procedures all Securities
surrendered for transfer, exchange, payment or cancellation and shall deliver a certificate of disposition to the Company. The Company may not issue new Securities to replace Securities it has paid in full or delivered to the Trustee for
cancellation. 

  
 19 













 Section 2.12. CUSIP Numbers. The Company in issuing the Securities may use
“CUSIP” and “CINS” numbers (if then generally in use), and the Trustee shall use CUSIP numbers or CINS numbers, as the case may be, in notices of redemption or exchange as a convenience to Holders and no representation shall be
made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption or exchange. 

Section 2.13. Defaulted Interest. If the Company defaults in a payment of interest on the Registered Securities, it shall pay, or
shall deposit with the Paying Agent money in immediately available funds sufficient to pay, the defaulted interest plus (to the extent lawful) any interest payable on the defaulted interest (as may be specified in the terms thereof, established
pursuant to Section 2.03) to the Persons who are Holders on a subsequent special record date, which shall mean the 15th day next preceding the date fixed by the Company for the payment of defaulted interest, whether or not such day is a
Business Day. At least 15 days before such special record date, the Company shall mail to each Holder of such Registered Securities and to the Trustee a notice that states the special record date, the payment date and the amount of defaulted
interest to be paid. 
 Section 2.14. Series May Include Tranches. A series of Securities may include one or more tranches (each
a “tranche”) of Securities, including Securities issued in a Periodic Offering. The Securities of different tranches may have one or more different terms, including authentication dates and public offering prices, but all the
Securities within each such tranche shall have identical terms, including authentication date and public offering price. Notwithstanding any other provision of this Indenture, with respect to Sections 2.02 (other than the fourth, sixth and
seventh paragraphs thereof) through 2.04, 2.07, 2.08, 2.10, 3.01 through 3.05, 4.02, 6.01 through 6.14, 8.01 through 8.07, 9.02 and Section 10.07, if any series of Securities includes more than one tranche, all provisions of such sections
applicable to any series of Securities shall be deemed equally applicable to each tranche of any series of Securities in the same manner as though originally designated a series unless otherwise provided with respect to such series or tranche
pursuant to Section 2.03. In particular, and without limiting the scope of the next preceding sentence, any of the provisions of such sections which provide for or permit action to be taken with respect to a series of Securities shall also be
deemed to provide for and permit such action to be taken instead only with respect to Securities of one or more tranches within that series (and such provisions shall be deemed satisfied thereby), even if no comparable action is taken with respect
to Securities in the remaining tranches of that series. 
 ARTICLE 3 

REDEMPTION 
 Section 3.01.
Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series which are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 2.03 for Securities of such series. 

  
 20 













 Section 3.02. Notice of Redemption; Partial Redemptions. Notice of redemption to
the Holders of Registered Securities of any series to be redeemed as a whole or in part at the option of the Company shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 30 days and not more than
60 days prior to the date fixed for redemption to such Holders of Registered Securities of such series at their last addresses as they shall appear upon the registry books. Notice of redemption to the Holders of Unregistered Securities of any
series to be redeemed as a whole or in part who have filed their names and addresses with the Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act, shall be given by mailing notice of such redemption, by first class mail, postage
prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption, to such Holders at such addresses as were so furnished to the Trustee (and, in the case of any such notice given by the Company, the Trustee shall
make such information available to the Company for such purpose). Notice of redemption to all other Holders of Unregistered Securities of any series to be redeemed as a whole or in part shall be published in an Authorized Newspaper in The City of
New York, or with respect to any Security the interest on which is based on the offered quotations in the interbank Eurodollar market for dollar deposits in an Authorized Newspaper in London, in each case, once in each of three successive
calendar weeks, the first publication to be not less than 30 days nor more than 60 days prior to the date fixed for redemption. Any notice which is mailed or published in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the Holder receives the notice. Failure to give notice by mail, or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of
the proceedings for the redemption of any other Security of such series. 
 The notice of redemption to each such Holder shall specify the
principal amount of each Security of such series held by such Holder to be redeemed, the CUSIP numbers of the Securities to be redeemed, the date fixed for redemption, the redemption price, or if not then ascertainable, the manner of calculation
thereof, the place or places of payment, that payment will be made upon presentation and surrender of such Securities and, in the case of Securities with coupons attached thereto, of all coupons appertaining thereto maturing after the date fixed for
redemption, that such redemption is pursuant to the mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be paid as specified in such notice and that on and after said date
interest thereon or on the portions thereof to be redeemed will cease to accrue. In case any Security of a series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and
shall state that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of such series and tenor in principal amount equal to the unredeemed portion thereof will be issued. 

The notice of redemption of Securities of any series to be redeemed at the option 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. 
 On or before 10:00 a.m. New York City
time on the redemption date or, in the case of Unregistered Securities, on or before 10:00 a.m. New York City time on the Business Day prior to the redemption date specified in the notice of redemption given as provided in this Section,
the Company will deposit with the Trustee or with one or more Paying Agents (or, if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 2.06) an amount of money sufficient to redeem on
the redemption date all the Securities of such series so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption. If all of the outstanding Securities of a series are to be redeemed,
the 

  
 21 













 
Company will deliver to the Trustee at least 10 days prior to the last date on which notice of redemption may be given to Holders pursuant to the first paragraph of this Section 3.02
(or such shorter period as shall be acceptable to the Trustee) an Officer’s Certificate stating that all such Securities are to be redeemed. If less than all the outstanding Securities of a series are to be redeemed, the Company will deliver to
the Trustee at least 15 days prior to the last date on which notice of redemption may be given to Holders pursuant to the first paragraph of this Section 3.02 (or such shorter period as shall be acceptable to the Trustee) an Officer’s
Certificate stating the aggregate principal amount of such Securities to be redeemed. In the case of any redemption of Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, or (b) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities or elsewhere in this Indenture, the Company shall deliver to the Trustee, prior to the giving
of any notice of redemption to Holders pursuant to this Section, an Officer’s Certificate evidencing compliance with such restriction or condition. 

If less than all the Securities of a series are to be redeemed, the Trustee shall select, pro rata, by lot or in such manner as it shall deem
appropriate and fair, Securities of such series to be redeemed in whole or in part. Securities may be redeemed in part in principal amounts equal to authorized denominations for Securities of such series. The Trustee shall promptly notify the
Company in writing of the Securities of such series selected for redemption and, in the case of any Securities of such series selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless
the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is
to be redeemed. 
 Section 3.03. Payment of Securities Called for Redemption. If notice of redemption has been given as above
provided, the Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for
redemption, and on and after such date (unless the Company shall default in the payment of such Securities at the redemption price, together with interest accrued to such date) interest on the Securities or portions of Securities so called for
redemption shall cease to accrue, and the unmatured coupons, if any, appertaining thereto shall be void and, except as provided in Sections 7.12 and 8.02, such Securities shall cease from and after the date fixed for redemption to be entitled
to any benefit under this Indenture, and the Holders thereof shall have no right in respect of such Securities except the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and
surrender of such Securities at a place of payment specified in said notice, together with all coupons, if any, appertaining thereto maturing after the date fixed for redemption, said Securities or the specified portions thereof shall be paid and
redeemed by the Company at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided that payment of interest becoming due on or prior to the date fixed for redemption shall be payable
in the case of Securities with coupons attached thereto, to the Holders of the coupons for such interest upon surrender thereof, and in the case of Registered Securities, to the Holders of such Registered Securities registered as such on the
relevant record date subject to the terms and provisions of Sections 2.04 and 2.13 hereof. 

  
 22 













 If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue Discount Security) borne by such Security. 

If any Security with coupons attached thereto is surrendered for redemption and is not accompanied by all appurtenant coupons maturing after
the date fixed for redemption, the surrender of such missing coupon or coupons may be waived by the Company and the Trustee, if there be furnished to each of them such security or indemnity as they may require to save each of them harmless. 

Upon presentation of any Security of any series redeemed in part only, the Company shall execute and the Trustee shall authenticate and
deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of such series and tenor (with any unmatured coupons attached), of authorized denominations, in principal amount equal to the unredeemed
portion of the Security so presented. 
 Section 3.04. Exclusion of Certain Securities from Eligibility for Selection for
Redemption. Securities shall be excluded from eligibility for selection for redemption if they are identified by registration and certificate number in a written statement signed by an authorized officer of the Company and delivered to the
Trustee at least 40 days prior to the last date on which notice of redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by, either (a) the Company or (b) an entity specifically
identified in such written statement as directly or indirectly controlling or controlled by or under direct or indirect common control with the Company. 

Section 3.05. Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of the Securities of any series is herein referred to as an
“optional sinking fund payment.” The date on which a sinking fund payment is to be made is herein referred to as the “sinking fund payment date.” 

In lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities in cash, the Company may at
its option (a) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except through a mandatory sinking fund payment) by the Company or receive credit for Securities of such series (not previously so
credited) theretofore purchased or otherwise acquired (except as aforesaid) by the Company and delivered to the Trustee for cancellation pursuant to Section 2.11, (b) receive credit for optional sinking fund payments (not previously so
credited) made pursuant to this Section, or (c) receive credit for Securities of such series (not previously so credited) redeemed by the Company at the option of the Company pursuant to the terms of such Securities or through any optional
sinking fund payment. Securities so delivered or credited shall be received or credited by the Trustee at the sinking fund redemption price specified in such Securities. 

  
 23 













 On or before the sixtieth day next preceding each sinking fund payment date for any
series, or such shorter period as shall be acceptable to the Trustee, the Company will deliver to the Trustee an Officer’s Certificate (a) specifying the portion of the mandatory sinking fund payment to be satisfied by payment of cash and
the portion to be satisfied by credit of specified Securities of such series and the basis for such credit, (b) stating that none of the specified Securities of such series has theretofore been so credited, (c) stating that no defaults in
the payment of interest or Events of Default with respect to such series have occurred (which have not been waived or cured) and are continuing and (d) stating whether or not the Company intends to exercise its right to make an optional sinking
fund payment with respect to such series and, if so, specifying the amount of such optional sinking fund payment which the Company intends to pay on or before the next succeeding sinking fund payment date. Any Securities of such series to be
credited and required to be delivered to the Trustee in order for the Company to be entitled to credit therefor as aforesaid which have not theretofore been delivered to the Trustee shall be delivered for cancellation pursuant to Section 2.11
to the Trustee with such Officer’s Certificate (or reasonably promptly thereafter if acceptable to the Trustee). Such Officer’s Certificate shall be irrevocable and upon its receipt by the Trustee the Company shall become unconditionally
obligated to make all the cash payments or delivery of Securities therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Company, on or before any such sixtieth day, to deliver such
Officer’s Certificate and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute, on and as of such date, the irrevocable election of the Company (i) that the mandatory sinking fund payment for
such series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect thereof and (ii) that the Company will make no optional sinking fund
payment with respect to such series as provided in this Section. 
 If the sinking fund payment or payments (mandatory or optional or both)
to be made in cash on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $50,000 (or a lesser sum if the Company shall so request with respect to the Securities of
any series), such cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of such series at the sinking fund redemption price thereof together with accrued interest thereon to the date fixed for
redemption. If such amount shall be $50,000 (or such lesser sum) or less and the Company makes no such request then it shall be carried over until a sum in excess of $50,000 (or such lesser sum) is available. The Trustee shall select, in the manner
provided in Section 3.02, for redemption on such sinking fund payment date a sufficient principal amount of Securities of such series to absorb said cash, as nearly as may be, and shall (if requested in writing by the Company) inform the
Company of the serial numbers of the Securities of such series (or portions thereof) so selected. Securities shall be excluded from eligibility for redemption under this Section if they are identified by registration and certificate number in an
Officer’s Certificate delivered to the Trustee at least 60 days prior to the sinking fund payment date as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Company or (b) an entity
specifically identified in such Officer’s Certificate as directly or indirectly controlling or controlled by or under direct or indirect common control with the Company. The Trustee, in the name and at the expense of the Company (or the
Company, if it shall so request the Trustee in writing) shall cause notice of redemption of the Securities of such series to be given in substantially the manner provided in Section 3.02 (and with the effect provided in Section 3.03) for
the redemption of Securities of such series in part at the option of the Company. The amount of any sinking fund payments not so applied or allocated to the redemption of Securities of such series shall be added to the next cash sinking fund payment
for such series and, together with 

  
 24 













 
such payment, shall be applied in accordance with the provisions of this Section. Any and all sinking fund moneys held on the stated maturity date of the Securities of any particular series (or
earlier, if such maturity is accelerated), which are not held for the payment or redemption of particular Securities of such series shall be applied, together with other moneys, if necessary, sufficient for the purpose, to the payment of the
Principal of, and interest on, the Securities of such series at maturity. 
 On or before 10:00 a.m. New York City time on each
sinking fund payment date or, in the case of Unregistered Securities, 10:00 a.m. New York City time on the Business Day prior to the sinking fund payment date, the Company shall pay to the Trustee in cash or shall otherwise provide for the
payment of all interest accrued to the date fixed for redemption on Securities to be redeemed on the next following sinking fund payment date. 

The Trustee shall not redeem or cause to be redeemed any Securities of a series with sinking fund moneys or mail any notice of redemption of
Securities of such series by operation of the sinking fund during the continuance of a Default in payment of interest on such Securities or of any Event of Default except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the Company a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for
such series at the time when any such Default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the continuance of such Default or Event of Default, be deemed to have been collected under
Article 6 and held for the payment of all such Securities. In case such Event of Default shall have been waived as provided in Section 6.04 or the Default cured on or before the sixtieth day preceding the sinking fund payment date in
any year, such moneys shall thereafter be applied on the next succeeding sinking fund payment date in accordance with this Section to the redemption of such Securities. 

ARTICLE 4 
 COVENANTS 

Section 4.01. Payment of Securities. The Company shall pay the Principal of and interest on the Securities on the dates and in the
manner provided in the Securities and this Indenture. The interest on Securities with coupons attached (together with any additional amounts payable pursuant to the terms of such Securities) shall be payable only upon presentation and surrender of
the several coupons for such interest installments as are evidenced thereby as they severally mature. The interest on any temporary Unregistered Securities (together with any additional amounts payable pursuant to the terms of such Securities) shall
be paid, as to the installments of interest evidenced by coupons attached thereto, if any, only upon presentation and surrender thereof, and, as to the other installments of interest, if any, only upon presentation of such Unregistered Securities
for notation thereon of the payment of such interest. The interest on Registered Securities (together with any additional amounts payable pursuant to the terms of such Securities) shall be payable only to the Holders thereof (subject to
Section 2.04) and at the option of the Company may be paid by mailing checks for such interest payable to or upon the written order of such Holders at their last addresses as they appear on the Security Register of the Company. 

  
 25 













 Notwithstanding any provisions of this Indenture and the Securities of any series to the
contrary, if the Company and a Holder of any Registered Security so agree, payments of interest on, and any portion of the Principal of, such Holder’s Registered Security (other than interest payable at maturity or on any redemption or
repayment date or the final payment of Principal on such Security) shall be made by the Paying Agent, upon receipt from the Company of immediately available funds by 11:00 a.m., New York City time (or such other time as may be agreed to
between the Company and the Paying Agent), directly to the Holder of such Security (by wire transfer through the Fedwire Funds Service or otherwise) if the Holder has delivered written instructions to the Trustee 15 days prior to such payment
date requesting that such payment will be so made and designating the bank account to which such payments shall be so made and in the case of payments of Principal, surrenders the same to the Trustee in exchange for a Security or Securities
aggregating the same principal amount as the unredeemed principal amount of the Securities surrendered. The Trustee shall be entitled to rely on the last instruction delivered by the Holder pursuant to this Section 4.01 unless a new instruction
is delivered 15 days prior to a payment date. The Company will indemnify and hold each of the Trustee and any Paying Agent harmless against any loss, liability or expense (including attorneys’ fees) resulting from any act or omission to
act on the part of the Company or any such Holder in connection with any such agreement or from making any payment in accordance with any such agreement. 

The Company shall pay interest on overdue Principal, and interest on overdue installments of interest, to the extent lawful, at the rate per
annum specified in the Securities. 
 Section 4.02. Maintenance of Office or Agency. The Company will maintain in the
United States of America an office or agency where Securities may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Company hereby initially designates the [●], located in [●], as such office or agency of the Company. The Company will give prompt written notice to the Trustee of the location, and any change in the
location, of such office 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 address of the Trustee set forth in Section 10.02. 
 The Company will maintain one or more agencies in a city or
cities located outside the United States of America (including any city in which such an agency is required to be maintained under the rules of any stock exchange on which the Securities of any series are listed) where the Unregistered
Securities, if any, of each series and coupons, if any, appertaining thereto may be presented for payment. No payment on any Unregistered Security or coupon will be made upon presentation of such Unregistered Security or coupon at an agency of the
Company within the United States of America nor will any payment be made by transfer to an account in, or by mail to an address in, the United States of America unless, pursuant to applicable United States laws and regulations then in
effect, such payment can be made without adverse tax consequences to the Company. Notwithstanding the foregoing, if full payment in United States Dollars (“Dollars”) at each agency maintained by the Company outside the
United States of America for payment on such Unregistered Securities or coupons appertaining thereto is illegal or effectively precluded by exchange controls or other similar restrictions, payments in Dollars of Unregistered Securities of any
series and coupons appertaining thereto which are payable in Dollars may be made at an agency of the Company maintained in the United States of America. 

  
 26 













 The Company may also from time to time designate one or more other offices or agencies where
the Securities of any series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the United States of America 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 4.03. Securityholders’ Lists. The Company will furnish or cause to be furnished
to the Trustee a list in such form as the Trustee may reasonably require of the names and addresses of the holders of the Securities pursuant to Section 312 of the Trust Indenture Act of 1939 (a) semi-annually not more than 15 days
after each record date for the payment of semi-annual interest on the Securities, as hereinabove specified, as of such record date, and (b) at such other times
as the Trustee may request in writing, within thirty days after receipt by the Company of any such request as of a date not more than 15 days prior to the time such information is furnished. 

Section 4.04. Certificate to Trustee. The Company will furnish to the Trustee annually, on or before a date not more than four
months after the end of its fiscal year (which, on the date hereof, is a calendar year), a brief certificate (which need not contain the statements required by Section 10.04) from its principal executive, financial or accounting officer as to
his or her knowledge of the compliance of the Company with all conditions and covenants under this Indenture (such compliance to be determined without regard to any period of grace or requirement of notice provided under this Indenture) which
certificate shall comply with the requirements of the Trust Indenture Act. Such certificate need not include a reference to any non-compliance that has been fully cured prior to the date as of which such
certificate speaks. 
 Section 4.05. Reports by the Company. So long as any Securities are outstanding, the Company shall file
with the Trustee, within 15 days after the Company files the same with the Commission, copies of the annual reports and of the information, documents, and other reports which the Company may be required to file with the Commission pursuant to
Section 13 or Section 15(d) of the Exchange Act. The Company shall be deemed to have complied with the previous sentence to the extent that such information, documents and reports are filed with the Commission via its “EDGAR”
system (or any successor electronic delivery procedure) or posted on its website. 
 Delivery of such reports, information and documents to
the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s
compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). 

  
 27 













 Section 4.06. Additional Amounts. 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 and at least 10 days prior to each date of payment of Principal of or interest on the Securities of that
series if there has been a change with respect to the matters set forth in the below-mentioned Officer’s Certificate, the Company shall furnish to the Trustee and the principal paying agent, if other than the Trustee, an Officer’s
Certificate instructing the Trustee and such paying agent whether such payment of Principal of or interest on the Securities of that series shall be made to Holders of the Securities of that series without withholding or deduction for or on account
of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding or deduction shall be required, then such Officer’s Certificate shall specify by country the amount, if any, required to be
withheld or deducted on such payments to such Holders and shall certify the fact that additional amounts will be payable and the amounts so payable to each Holder, and the Company shall pay to the Trustee or such paying agent the additional amounts
required to be paid by this Section. 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 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 Officer’s Certificate furnished pursuant to this Section. 

Whenever in this Indenture there is mentioned, in any context, the payment of the Principal of or interest or any other amounts on, or in
respect of, any Security of any series, such mention shall be deemed to include mention of the payment of additional amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, additional
amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of additional amounts (if applicable) in any provision hereof shall not be construed as excluding the payment of additional amounts
in those provisions hereof where such express mention is not made.

effect, or consents to the entry of an order for relief in an involuntary case under any such law, (ii) consents to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar
official of the Company or for all or substantially all of the property and assets of the Company or (iii) effects any general assignment for the benefit of creditors; or 

(f) any other Event of Default established pursuant to Section 2.03 with respect to the Securities of such series occurs. 

  
 29 













 Section 6.02. Acceleration. (a) If an Event of Default other than as
described in clauses (d) or (e) of Section 6.01 with respect to the Securities of any series then outstanding occurs and is continuing, then, and in each and every such case, except for any series of Securities the principal of which
shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities of any such series then outstanding hereunder (all such series voting together as a single class) by
notice in writing to the Company (and to the Trustee if given by Securityholders), may declare the entire principal (or, if the Securities of any such series are Original Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of such series established pursuant to Section 2.03) of all Securities of such series, and the interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become
immediately due and payable. 
 (a) If an Event of Default described in clause (d) or (e) of Section 6.01 occurs and is
continuing, then the principal amount (or, if any Securities are Original Issue Discount Securities, such portion of the principal as may be specified in the terms thereof established pursuant to Section 2.03) of all the Securities then
outstanding and interest accrued thereon, if any, shall be and become immediately due and payable, without any notice or other action by any Holder or the Trustee, to the full extent permitted by applicable law. 

The foregoing provisions, however, are subject to the condition that if, at any time after the principal (or, if the Securities are Original
Issue Discount Securities, such portion of the principal as may be specified in the terms thereof established pursuant to Section 2.03) of the Securities of any series (or of all the Securities, as the case may be) shall have been so declared
or become due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured
installments of interest upon all the Securities of each such series (or of all the Securities, as the case may be) and the principal of any and all Securities of each such series (or of all the Securities, as the case may be) which shall have
become due otherwise than by acceleration (with interest upon such principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at the same rate as the rate of interest or Yield
to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of each such series to the date of such payment or deposit) and such amount as shall be sufficient to cover all amounts owing the Trustee under
Section 7.07, and if any and all Events of Default under the Indenture, other than the non-payment of the principal of Securities which shall have become due by acceleration, shall have been cured, waived
or otherwise remedied as provided herein, then and in every such case the Holders of a majority in aggregate principal amount of all the then outstanding Securities of all such series that have been accelerated (voting as a single class), by written
notice to the Company and to the Trustee, may waive all defaults with respect to all such series (or with respect to all the Securities, as the case may be) and rescind and annul such declaration and its consequences, but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon. 

  
 30 













 For all purposes under this Indenture, if a portion of the principal of any Original Issue
Discount Securities shall have been accelerated and declared or become due and payable pursuant to the provisions hereof, then, from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such
Original Issue Discount Securities shall be deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall
be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Securities. 

Section 6.03. Other Remedies. If a payment default or an Event of Default with respect to the Securities of any series occurs and
is continuing, the Trustee may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of Principal of and interest on the Securities of such series or to enforce the
performance of any provision of the Securities of such series or this Indenture. 
 The Trustee may maintain a proceeding even if it does
not possess any of the Securities or does not produce any of them in the proceeding. 
 Section 6.04. Waiver of Past Defaults.
Subject to Sections 6.02, 6.07 and 9.02, the Holders of at least a majority in principal amount (or, if the Securities are Original Issue Discount Securities, such portion of the principal as is then accelerable under Section 6.02) of the
outstanding Securities of all series affected (voting as a single class), by notice to the Trustee, may waive an existing Default or Event of Default with respect to the Securities of such series and its consequences, except a Default in the payment
of Principal of or interest on any Security as specified in clauses (a) or (b) of Section 6.01 or in respect of a covenant or provision of this Indenture which 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 with respect to the Securities of such series 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 Event of Default or impair any right consequent thereto. 

Section 6.05. Control by Majority. Subject to Sections 7.01 and 7.02(e), the Holders of at least a majority in aggregate
principal amount (or, if any Securities are Original Issue Discount Securities, such portion of the principal as is then accelerable under Section 6.02) of the outstanding Securities of all series affected (voting as a single class) may direct
the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities of such series by this Indenture; provided, that the
Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in
the giving of such direction; and provided further, that the Trustee may take any other action it deems proper that is not inconsistent with any directions received from Holders of Securities pursuant to this Section 6.05. 

  
 31 













 Section 6.06. Limitation on Suits. No Holder of any Security of any series may
institute any proceeding, judicial or otherwise, with respect to this Indenture or the Securities of such series, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 

(a) such Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Securities of such
series; 
 (b) the Holders of at least 25% in aggregate principal amount of outstanding Securities of all such series affected 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; 
 (c)
such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liabilities or expenses to be incurred in compliance with such request; 

(d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
 (e) during such 60-day period, the Holders of a majority in aggregate principal amount of the
outstanding Securities of all such affected series have not given the Trustee a direction that is inconsistent with such written request. 

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder.

 Section 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security to receive payment of Principal of or interest, if any, on such Holder’s Security on or after the respective due dates expressed on such Security, or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08. Collection Suit by
Trustee. If an Event of Default with respect to the Securities of any series in payment of Principal or interest specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own
name and as trustee of an express trust against the Company for the whole amount (or such portion thereof as specified in the terms established pursuant to Section 2.03 of Original Issue Discount Securities) of Principal of, and accrued
interest remaining unpaid on, together with interest on overdue Principal of, and, to the extent that payment of such interest is lawful, interest on overdue installments of interest on, the Securities of such series, in each case at the rate or
Yield to Maturity (in the case of Original Issue Discount Securities) specified in such Securities, and such further amount as shall be sufficient to cover all amounts owing the Trustee under Section 7.07. 

Section 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any claim for amounts due the Trustee under Section 7.07) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor on the
Securities), its creditors or its property and shall be entitled and empowered to collect and receive any moneys, securities or other property payable or deliverable upon conversion or exchange of the Securities or upon 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 

  
 32 













 
pay to the Trustee any amount due to it under Section 7.07. Nothing herein contained shall be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any
Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10. Application of Proceeds. Any moneys collected by the Trustee pursuant to this Article in respect of the Securities
of any series shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of Principal or interest, upon presentation of the several Securities and coupons appertaining
to such Securities in respect of which moneys have been collected and noting thereon the payment, or issuing Securities of such series and tenor in reduced principal amounts in exchange for the presented Securities of such series and tenor if only
partially paid, or upon surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee under
Section 7.07 applicable to the Securities of such series in respect of which moneys have been collected; 

SECOND: Subject to Article 11, in case the principal of the Securities of such series in respect of which moneys
have been collected shall not have become and be then due and payable, to the payment of interest on the Securities of such series in default in the order of the maturity of the installments of such interest, with interest (to the extent that such
interest has been collected by the Trustee) upon the overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such payments to be
made ratably to the persons entitled thereto, without discrimination or preference; 
 THIRD: Subject to
Article 11, in case the principal of the Securities of such series in respect of which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the
Securities of such series for Principal and interest, with interest upon the overdue Principal, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the same rate as the rate of interest
or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series,
then to the payment of such Principal and interest or Yield to Maturity, without preference or priority of Principal over interest or Yield to Maturity, or of interest or Yield to Maturity over Principal, or of any installment of interest over any
other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such Principal and accrued and unpaid interest or Yield to Maturity; and 

FOURTH: To the payment of the remainder, if any, to the Company or any other person lawfully entitled thereto. 

  
 33 













 Section 6.11. 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 to their former positions hereunder and thereafter all rights and remedies of the Company, Trustee and the Holders shall continue as though
no such proceeding had been instituted. 
 Section 6.12. Undertaking for Costs. 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 or omitted by it as Trustee, in either case in respect to the Securities of any series, a court may require any party litigant in such suit (other than the Trustee)
to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant (other than the Trustee) in the suit having due regard to the merits and good faith
of the claims or defenses made by the party litigant. This Section 6.12 does not apply to a suit by a Holder pursuant to Section 6.07, a suit instituted by the Trustee or a suit by Holders of more than 10% in principal amount of the
outstanding Securities of such series. 
 Section 6.13. Rights and Remedies Cumulative. Except as otherwise provided with
respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Securities in Section 2.08, 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 6.14. Delay or Omission not Waiver. No delay or omission of the Trustee or of any Holder 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 6 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. 

ARTICLE 7 
 TRUSTEE 

Section 7.01. General. The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act and as set
forth herein. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of
any of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability or expense. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of this Article 7. 

  
 34 













 Section 7.02. Certain Rights of Trustee. Subject to Trust Indenture Act
Sections 315(a) through (d): 
 (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution,
certificate, Officer’s Certificate, Opinion of Counsel (or both), statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by
it to be genuine and to have been signed or presented by the proper person or persons. The Trustee need not investigate any fact or matter stated in the document, but the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit; 
 (b) before the Trustee acts or refrains from acting, it may require an Officer’s
Certificate and/or an Opinion of Counsel, which shall conform to Section 10.04 and shall cover such other matters as the Trustee may reasonably request. The Trustee shall not be liable for any action it takes or omits to take in good faith in
reliance on such certificate or opinion. Subject to Sections 7.01 and 7.02, whenever in the administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking
or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved
and established by an Officer’s Certificate delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by
it under the provisions of this Indenture upon the faith thereof; 
 (c) the Trustee may act through its attorneys and agents not regularly
in its employ and shall not be responsible for the misconduct or negligence of any agent or attorney appointed with due care; 
 (d) any
request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officer’s Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be
evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; 
 (e) the Trustee shall be
under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the
costs, expenses and liabilities that might be incurred by it in compliance with such request or direction; 
 (f) the Trustee shall not be
liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers or for any action it takes or omits to take in accordance with the direction of the Holders in accordance with
Section 6.05 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 

(g) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; and 

  
 35 













 (h) prior to the occurrence of an Event of Default hereunder and after the curing or waiving
of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, Officer’s Certificate, Opinion of Counsel, Board Resolution, statement, instrument, opinion,
report, notice, request, consent, order, approval, appraisal, bond, debenture, note, coupon, security, or other paper or document unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the
Securities of all series affected then outstanding; provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to proceeding. 

Section 7.03. Individual Rights of Trustee. The Trustee, in its individual or any other capacity, may become the owner or pledgee
of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Trust Indenture Act
Sections 310(b) and 311. For purposes of Trust Indenture Act Section 311(b)(4) and (6), the following terms shall mean: 
 (a)
“cash transaction” means any transaction in which full payment for goods or securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and
payable upon demand; and 
 (b) “self-liquidating paper” means any draft, bill of exchange, acceptance or obligation which
is made, drawn, negotiated or incurred by the Company for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession
of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with
the creation of the creditor relationship with the Company arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation. 

Section 7.04. Trustee’s Disclaimer. The recitals contained herein and in the Securities (except the
Trustee’s certificate of authentication) shall be taken as statements of the Company and not of the Trustee and the Trustee assumes no responsibility for the correctness of the same. Neither the Trustee nor any of its agents (a) makes any
representation as to the validity or adequacy of this Indenture or the Securities and (b) shall be accountable for the Company’s use or application of the proceeds from the Securities. 

  
 36 













 Section 7.05. Notice of Default. If any Default with respect to the Securities
of any series occurs and is continuing and if such Default is known to the actual knowledge of a Responsible Officer with the Corporate Trust Department of the Trustee, the Trustee shall give to each Holder of Securities of such series notice of
such Default within 90 days after it occurs (a) if any Unregistered Securities of such series are then outstanding, to the Holders thereof, by publication at least once in an Authorized Newspaper in the Borough of Manhattan, The City of
New York and at least once in an Authorized Newspaper in London and (b) to all Holders of Securities of such series in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, unless such Default shall have
been cured or waived before the mailing or publication of such notice; provided, however, that, except in the case of a Default in the payment of the Principal of or interest on any Security, the Trustee shall be protected in
withholding such notice if the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 7.06. Reports by Trustee to Holders. The Trustee shall transmit to Holders such reports concerning the Trustee and its
actions under this Indenture as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto. If required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within 60 days after
each May 15 following the date of this Indenture, deliver to Holders a brief report, dated as of such May 15, which complies with the provisions of such Section 313(a). 

A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Company. The Company will promptly notify the Trustee when any Securities are listed on any stock exchange. 

Section 7.07. Compensation and Indemnity. The Company shall pay to the Trustee such compensation as shall be agreed upon in
writing from time to time for its services. The compensation of the Trustee shall not be limited by any law on compensation of a Trustee of an express trust. The Company shall reimburse the Trustee and any predecessor Trustee upon request for all
reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Trustee or such predecessor Trustee. Such expenses shall include the reasonable
compensation and expenses of the Trustee’s or such predecessor Trustee’s agents, counsel and other persons not regularly in their employ. 

The Company shall indemnify the Trustee and any predecessor Trustee for, and hold them harmless against, any loss or liability or expense
incurred by them without negligence or bad faith on their part arising out of or in connection with the acceptance or administration of this Indenture and the Securities or the issuance of the Securities or of series thereof or the trusts hereunder
and the performance of duties under this Indenture and the Securities, including the costs and expenses of defending themselves against or investigating any claim or liability and of complying with any process served upon them or any of their
officers in connection with the exercise or performance of any of their powers or duties under this Indenture and the Securities. 
 To
secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, in its capacity as Trustee, except money or property held in
trust to pay Principal of, and interest on particular Securities. 

  
 37 













 The obligations of the Company under this Section to compensate and indemnify the Trustee
and each predecessor Trustee and to pay or reimburse the Trustee and each predecessor Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this
Indenture or the rejection or termination of this Indenture under bankruptcy law. Such additional indebtedness shall be a senior claim to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held
in trust for the benefit of the Holders of particular Securities or coupons, and the Securities are hereby subordinated to such senior claim. Without prejudice to any other rights available to the Trustee under applicable law, if the Trustee renders
services and incurs expenses following an Event of Default under Section 6.01(d) or Section 6.01(e) hereof, the parties hereto and the holders by their acceptance of the Securities hereby agree that such expenses are intended to constitute
expenses of administration under any bankruptcy law. 
 Section 7.08. Replacement of Trustee. A resignation or removal of the
Trustee as Trustee with respect to the Securities of any series and appointment of a successor Trustee as Trustee with respect to the Securities of any series shall become effective only upon the successor Trustee’s acceptance of appointment as
provided in this Section 7.08. 
 The Trustee may resign as Trustee with respect to the Securities of any series at any time by so
notifying the Company in writing. The Holders of a majority in principal amount of the outstanding Securities of any series may remove the Trustee as Trustee with respect to the Securities of such series by so notifying the Trustee in writing and
may appoint a successor Trustee with respect thereto with the consent of the Company. The Company may remove the Trustee as Trustee with respect to the Securities of any series if: (i) the Trustee is no longer eligible under Section 7.11
of this Indenture; (ii) the Trustee is adjudged a bankrupt or insolvent; (iii) a receiver or other public officer takes charge of the Trustee or its property; or (iv) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed as Trustee with respect to the Securities of any series, or if a vacancy exists in the office of Trustee
with respect to the Securities of any series for any reason, the Company shall promptly appoint a successor Trustee with respect thereto. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the
outstanding Securities of such series may appoint a successor Trustee in respect of such Securities to replace the successor Trustee appointed by the Company. If the successor Trustee with respect to the Securities of any series does not deliver its
written acceptance required by Section 7.09 within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the outstanding Securities of such series
may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect thereto. 
 The Company shall give
notice of any resignation and any removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee in respect of the Securities of such series to all Holders of Securities of such series. Each notice
shall include the name of the successor Trustee and the address of its Corporate Trust Office. 

  
 38 













 Notwithstanding replacement of the Trustee with respect to the Securities of any series
pursuant to this Section 7.08 and Section 7.09, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 

Section 7.09. 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 and subject to the lien provided for in Section 7.07, 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. 
 In
case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall
execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring
with respect to all 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. 

Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 

  
 39 













 No successor Trustee shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be eligible under this Article and qualified under Section 310(b) of the Trust Indenture Act. 

Section 7.10. Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation or national banking association, the resulting, surviving or transferee corporation or national banking association without any further act shall be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee herein. 
 Section 7.11. Eligibility. This Indenture
shall always have a Trustee who satisfies the requirements of Trust Indenture Act Section 310(a). The Trustee shall have a combined capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of
condition. 
 Section 7.12. Money Held in Trust. The Trustee shall not be liable for interest on any money received by it except
as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law and except for money held in trust under Article 8 of this Indenture. 

ARTICLE 8 
 SATISFACTION AND

Company shall have paid or caused to be paid the Principal of and interest on all the Securities of any series outstanding hereunder (other than Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid
as provided in Section 2.08) as and when the same shall have become due and payable, or (b) the Company shall have delivered to the Trustee for cancellation all Securities of any series theretofore authenticated (other than any Securities

(ii) the Company shall have irrevocably deposited or caused to be deposited with the Trustee as trust funds the entire amount in cash (other than moneys repaid by the Trustee or any paying agent to the Company in accordance with
Section 8.04) or U.S. Government Obligations, maturing as to principal and interest in such amounts and at such times as will insure (without consideration of the reinvestment of such interest) the availability of cash, or a combination
thereof, sufficient to pay at maturity or upon redemption all Securities of such series (other than any Securities of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in
Section 2.08) not theretofore delivered to the Trustee for cancellation, including principal and interest due or to become due on or prior to such date of maturity or redemption as the case may be, and if, in any such case, the Company is not
prohibited from making payments in respect of the Securities by Article 11 hereof and shall also pay or cause to be paid all other sums payable hereunder by the Company with respect to Securities of such series, then this Indenture shall cease
to be of further effect with respect to Securities of such series (except as to

such satisfaction of and discharging this Indenture with respect to such series; provided, that the rights of Holders of the Securities to receive amounts in respect of Principal of and interest on the Securities held by them shall not be
delayed longer than required by then-applicable mandatory rules or policies of any securities exchange upon which the Securities are listed. The Company agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly
incurred and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Securities of such series.

through any paying agent to the Holders of the particular Securities of such series for the payment or redemption of which such moneys have been deposited with the Trustee, of all sums due and to become due thereon for Principal and interest; but
such money need not be segregated from other funds except to the extent required by law. Funds and U.S. Government Obligations held in trust under Section 8.01, Section 8.05 or Section 8.06 shall not be subject to the claims of
the holders of Senior Indebtedness under Article 11. 
 Section 8.03. Repayment of Moneys Held by Paying Agent. In
connection with the satisfaction and discharge of this Indenture with respect to Securities of any series, all moneys then held by any paying agent under the provisions of this Indenture with respect to such series of Securities shall, upon demand
of the Company, be repaid to it or paid to the Trustee and thereupon such paying agent shall be released from all further liability with respect to such moneys. 

Section 8.04. Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two Years. Any moneys deposited with or paid to the
Trustee or any paying agent for the payment of the Principal of or interest on any Security of any series and not applied but remaining unclaimed for two years after the date upon which such Principal or interest shall have become due and payable,
shall, upon the written request of the Company and unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, be repaid to the Company by the Trustee for such series or such paying agent, and the
Holder of the Security of such series shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property laws, thereafter look only to the Company for any payment which such Holder may be entitled to
collect, and all liability of the Trustee or any paying agent with respect to such moneys shall thereupon cease. 

  
 41

Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of the Company’s exercise of its option under this Section 8.05 and will be subject to federal income tax on the same amount and
in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred, which Opinion of Counsel must be based upon a ruling of the Internal Revenue Service to the same effect or a change in
applicable federal income tax law or related treasury regulations after the date of this Indenture or (y) a ruling directed to the Trustee received from the Internal Revenue Service to the same effect as the aforementioned Opinion of Counsel
and (B) an Opinion of Counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940 and after the passage of 123 days following the deposit, the trust fund will not be subject to the

 42 













 (iii) immediately after giving effect to such deposit on a pro forma basis,
no Event of Default, or event that after the giving of notice or lapse of time or both would become an Event of Default, shall have occurred and be continuing on the date of such deposit or during the period ending on the 123rd day after the date of
such deposit, and such deposit shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which the Company is bound; 

(iv) if at such time the Securities of such series are listed on a national securities exchange, the Company has delivered to
the Trustee an Opinion of Counsel to the effect that the Securities of such series will not be delisted as a result of such deposit, defeasance and discharge;

(a) with reference to this Section 8.06, the Company has deposited or caused to be irrevocably deposited with the Trustee (or another
qualifying trustee satisfying the requirements of Section 7.11) as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Securities of such series and the Indenture with respect
to the Securities of such series, (i) money in an amount or (ii) U.S. Government Obligations which through the payment of interest and principal in respect thereof in accordance with their terms will provide not later than one day

same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred and (ii) an Opinion of Counsel to the effect that the creation of the defeasance trust does not violate the
Investment Company Act of 1940 and after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section 547 of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and

(e) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under this Section have been complied with. 
 Section 8.07. Reinstatement. If the Trustee or paying
agent is unable to apply any monies or U.S. Government Obligations in accordance with Article 8 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 and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article until such time as the Trustee or paying agent
is permitted to apply all such monies or U.S. Government Obligations in accordance with Article 8; provided, however, that if the Company has made any payment of Principal of or interest on 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 monies or U.S. Government Obligations held by the Trustee or paying agent. 

Section 8.08. Indemnity. The Company shall pay and indemnify the Trustee (or other qualifying trustee, collectively for purposes

8.05 or 8.06 which, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount

Section 8.10. Qualifying Trustee. Any trustee appointed pursuant to Section 8.05 or 8.06 for the purpose of holding money or
U.S. Government Obligations deposited pursuant to such Sections shall be appointed under an agreement in form acceptable to the Trustee and shall provide to the Trustee a certificate, upon which certificate the Trustee shall be entitled to
conclusively rely, that all conditions precedent provided for herein to the related defeasance have been complied with. In no event shall the Trustee be liable for any acts or omissions of said trustee. 

ARTICLE 9 
 AMENDMENTS,
SUPPLEMENTS AND WAIVERS 
 Section 9.01. Without Consent of Holders. The Company and the Trustee may amend or supplement this
Indenture or the Securities of any series without notice to or the consent of any Holder: 
 (a) to cure any ambiguity, defect or
inconsistency in this Indenture; provided that such amendments or supplements shall not materially and adversely affect the interests of the Holders; 

(b) to comply with Article 5; 

(c) to comply with any requirements of the Commission in connection with the qualification of this Indenture under the Trust Indenture Act;

 (d) to evidence and provide for the acceptance of appointment hereunder with respect to the Securities of any or all series by a successor
Trustee and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, pursuant to the requirements of Section 7.09; 

(e) to establish the form or forms or terms of Securities of any series or of the coupons appertaining to such Securities as permitted by
Section 2.03; 
 (f) to provide for uncertificated or Unregistered Securities and to make all appropriate changes for such purpose; and

 (g) to make any change that does not materially and adversely affect the rights of any Holder. 

  
 45 













 Section 9.02. With Consent of Holders. Subject to Sections 6.04 and 6.07,
without prior notice to any Holders, the Company and the Trustee may amend this Indenture and the Securities of any series with the written consent of the Holders of a majority in principal amount of the outstanding Securities of all series affected
by such amendment (each such series voting as a separate class), and the Holders of a majority in principal amount of the outstanding Securities of all series affected thereby (each such series voting as a separate class) by written notice to the
Trustee may waive future compliance by the Company with any provision of this Indenture or the Securities of such series. 
 Notwithstanding
the provisions of this Section 9.02, without the consent of each Holder affected thereby, an amendment or waiver, including a waiver pursuant to Section 6.04, may not: 

(a) change the stated maturity of the Principal of, or any sinking fund obligation or any installment of interest on, such Holder’s
Security; 
 (b) reduce the Principal amount thereof or the rate of interest thereon (including any amount in respect of original issue
discount); 
 (c) reduce the above stated percentage of outstanding Securities the consent of whose holders is necessary to modify or amend
the Indenture with respect to the Securities of the relevant series; and 
 (d) reduce the percentage in principal amount of outstanding
Securities of the relevant series the consent of whose Holders is required for any supplemental indenture or for any waiver of compliance with certain provisions of this Indenture or certain Defaults and their consequences provided for in this
Indenture. 
 A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly
been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of Holders of Securities of such series with respect to such covenant or provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series or of the coupons appertaining to such Securities. 
 It shall not be necessary
for the consent of any Holder under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall give to the Holders affected
thereby a notice briefly describing the amendment, supplement or waiver. The Company will mail supplemental indentures to Holders upon request. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such supplemental indenture or waiver. 
 Section 9.03. Revocation and Effect of Consent.
Until an amendment or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the Security of the consenting
Holder, even if notation of the consent is not made on any Security. 

  
 46 













 
However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of its Security. Such revocation shall be effective only if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver shall become effective with respect to any Securities affected thereby on receipt by the Trustee of written consents from the
requisite Holders of outstanding Securities affected thereby. 
 The Company may, but shall not be obligated to, fix a record date (which
may be not less than five nor more than 60 days prior to the solicitation of consents) for the purpose of determining the Holders of the Securities of any series affected entitled to consent to any amendment, supplement or waiver. If a record
date is fixed, then, notwithstanding the immediately preceding paragraph, those Persons who were such Holders at such record date (or their duly designated proxies) and only those Persons shall be entitled to consent to such amendment, supplement or
waiver or to revoke any consent previously given, whether or not such Persons continue to be such Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. 

After an amendment, supplement or waiver becomes effective with respect to the Securities of any series affected thereby, it shall bind every
Holder of such Securities unless it is of the type described in any of clauses (a) through (d) of Section 9.02. In case of an amendment or waiver of the type described in clauses (a) through (d) of Section 9.02, the
amendment or waiver shall bind each such Holder who has consented to it and every subsequent Holder of a Security that evidences the same indebtedness as the Security of the consenting Holder. 

Section 9.04. Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of any Security, the
Trustee may require the Holder thereof to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder and the Trustee may place an appropriate notation on any Security
of such series thereafter authenticated. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security of the same series and tenor that reflects
the changed terms. 
 Section 9.05. Trustee to Sign Amendments, Etc. The Trustee shall be entitled to receive, and shall be
fully protected in relying upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article 9 is authorized or permitted by this Indenture, stating that all requisite consents
have been obtained or that no consents are required and stating that such supplemental indenture constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to customary
exceptions. The Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Section 9.06. Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article 9 shall
conform to the requirements of the Trust Indenture Act as then in effect.

reliance upon such waiver. 
 In case it shall be impracticable to give notice as herein contemplated, then such notification as shall be
made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

for the purpose of receiving payment thereof or on account thereof and for all other purposes, and neither the Company, the Trustee, nor any agent of the Company or the Trustee shall be affected by any notice to the contrary. The fact of the holding
by any Holder of an Unregistered Security, and the identifying number of such Security and the date of his holding the same, may be proved by the production of such Security or by a certificate executed by any trust company, bank, banker or
recognized securities dealer wherever situated satisfactory to the Trustee, if such certificate shall be deemed by the Trustee to be satisfactory. Each such certificate shall be dated and shall state that on the date thereof a Security bearing a
specified identifying number was deposited with or exhibited to such trust company, bank, banker or recognized securities dealer by the person named in such certificate. Any such certificate may be issued in respect of one or more Unregistered
Securities specified therein. The holding by the person named in any such certificate of any Unregistered Securities specified therein shall be presumed to continue for a period of one year from the date of such certificate unless at the time of any
determination of such holding (1) another certificate bearing a later date issued in respect of the same Securities shall be produced or (2) the Security specified in such certificate shall be produced by some other Person, or (3) the
Security specified in such certificate shall have ceased to be outstanding. Subject to Article 7, the fact and date of the execution of any such instrument and the amount and numbers of Securities held by the Person so executing such instrument
may also be proven in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in any other manner which the Trustee may deem sufficient. 

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the person in whose name any Registered Security shall
be registered upon the Security Register for such series as the absolute owner of such Registered Security (whether or not such Registered Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the Principal of and, subject to the provisions of this Indenture, interest on such Registered Security and for all other purposes; and neither the Company nor the Trustee nor any agent of the Company
or the Trustee shall be affected by any notice to the contrary.

The Trustee may make reasonable rules for action by or at a meeting of Holders. The Paying Agent or Registrar may make reasonable rules for its functions. 

Section 10.07. Payment Date Other Than a Business Day. Except as otherwise provided with respect to a series of Securities, if any
date for payment of Principal or interest on any Security shall not be a Business Day at any place of payment, then payment of Principal of or interest on such Security, as the case may be, need not be made on such date, but may be made on the next
succeeding Business Day at any place of payment with the same force and effect as if made on such date and no interest shall accrue in respect of such payment for the period from and after such date. 

Section 10.08. Governing Law. The laws of the State of New York shall govern this Indenture and the Securities.

agreements of the Trustee in this Indenture shall bind its successors. 
 Section 10.11. Duplicate Originals. The parties may

unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

Section 10.13. Table of Contents, Headings, Etc. The Table of Contents and headings of the Articles and Sections of this Indenture
have been inserted for convenience of reference only, are not to be considered a part hereof and shall in no way modify or restrict any of the terms and provisions hereof. 

Section 10.14. Incorporators, Stockholders, Officers and Directors of Company Exempt from Individual Liability. No recourse under
or upon any obligation, covenant or agreement contained in this Indenture or any indenture supplemental hereto, or in any Security or any coupons appertaining thereto, or because of any indebtedness evidenced thereby, shall be had against any
incorporator, as such or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities and the coupons appertaining thereto by
the holders thereof and as part of the consideration for the issue of the Securities and the coupons appertaining thereto. 

Section 10.15. Judgment Currency. The Company agrees, to the fullest extent that it may effectively do so under applicable law,
that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the Principal of or interest on 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 day on which final unappealable judgment is entered, unless such day is not a Business Day, then, to the extent permitted by applicable law, 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 preceding the day on which final unappealable judgment is entered and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any 

  
 51 













 
recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the Required Currency, except to the extent that such tender or
recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the
purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be affected by judgment being obtained
for any other sum due under this Indenture. 
 ARTICLE 11 

SUBORDINATION OF SECURITIES 

Section 11.01. Agreement to Subordinate. The Company covenants and agrees, and each Holder of Securities issued hereunder by his
acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to the provisions of this Article; and each person holding any Security, whether upon original issue or upon transfer, assignment or exchange thereof
accepts and agrees that the Principal of and interest on all Securities issued hereunder shall, to the extent and in the manner herein set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior
Indebtedness. 
 Section 11.02. Payments to Securityholders. No payments on account of Principal of or interest on the
Securities shall be made if at the time of such payment or immediately after giving effect thereto there shall exist a default in any payment with respect to any Senior Indebtedness, and such default shall not have been cured or waived or shall not
have ceased to exist. In addition, during the continuance of any default (other than a payment default) with respect to Designated Senior Indebtedness pursuant to which the maturity thereof may be accelerated, from and after the date of receipt by
the Trustee of written notice from the holders of such Designated Senior Indebtedness or from an agent of such holders, stating that such default has occurred and is continuing, no payments on account of Principal or interest in respect of the
Securities may be made by the Company for a period (“Payment Blockage Period”) commencing on the date of delivery of such notice and ending 179 days thereafter (unless such Payment Blockage Period shall be terminated by written
notice to the Trustee from the holders of such Designated Senior Indebtedness or from an agent of such holders, or such default has been cured or waived or has ceased to exist). Only one Payment Blockage Period may be commenced with respect to the
Securities during any period of 360 consecutive days. No Event of Default which existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Payment
Blockage Period shall be or be made the basis for the commencement of any subsequent Payment Blockage Period by the holders of such Designated Senior Indebtedness, unless such Event of Default shall have been cured or waived for a period of not less
than 90 consecutive days. 
 Upon any payment or distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to creditors upon any liquidation, dissolution, winding up, receivership, reorganization, assignment for the benefit of creditors, marshalling of assets and liabilities or any bankruptcy, insolvency or similar proceedings of
the Company, all amounts due or to become due upon all Senior Indebtedness shall first be paid in full, in cash or cash equivalents, or payment thereof provided for in accordance with its terms, before any payment is


  
 52 













 
made on account of the Principal of, or interest on the indebtedness evidenced by the Securities, and upon any such liquidation, dissolution, winding up, receivership, reorganization, assignment,
marshalling or proceeding, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Securities or the Trustee under this Indenture would be entitled, except
for the provisions hereof, shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, directly to the holders of Senior Indebtedness (pro rata to
such holders on the basis of the respective amounts of Senior Indebtedness held by such holders) or their respective representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any of such Senior
Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full (including, without limitation, except to the extent, if any, prohibited by mandatory provisions of law,
post-petition interest, in any such proceedings), after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution is made to the holders of the indebtedness evidenced by
the Securities or to the Trustee under this Indenture. 
 In the event that, notwithstanding the foregoing, any payment or distribution of
assets of the Company of any kind or character, whether in cash, property or securities, prohibited by the foregoing, shall be received by the Trustee under this Indenture or the Holders of the Securities before all Senior Indebtedness is paid in
full or provision is made for such payment in accordance with its terms, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of such Senior Indebtedness or their respective
representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any of such Senior Indebtedness may have been issued, as their respective interests may appear, for application to the payment of all
Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness. 

For purposes of this Article, the words, “cash, property or securities” shall not be deemed to include shares of stock of the
Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of arrangement, reorganization or readjustment, the payment of which is subordinated (at least to the extent provided in this Article
with respect to the Securities) to the payment of all Senior Indebtedness which may at the time be outstanding; provided, that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from any such arrangement,
reorganization or readjustment, and (ii) the rights of the holders of the Senior Indebtedness are not, without the consent of such holders, altered by such arrangement, reorganization or readjustment. The consolidation of the Company with, or
the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the sale, conveyance or transfer of all or substantially all of its property and assets to another corporation upon the terms and
conditions provided in Article 5 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section if such other corporation shall, as a part of such
consolidation, merger, sale, conveyance or transfer, comply with the conditions stated in Article 5. Nothing in this Section shall apply to claims of, or payments to, the Trustee under or pursuant to Article 7. This Section shall be
subject to the further provisions of Section 11.05. 

  
 53 













 Section 11.03. Subrogation of Securities. Subject to the payment in full of all
Senior Indebtedness, the Holders of the Securities shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness
until the principal of and interest on the Securities shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders
of the Securities or the Trustee on their behalf would be entitled except for the provisions of this Article, and no payment over pursuant to the provisions of this Article to the holders of Senior Indebtedness by Holders of the Securities or the
Trustee on their behalf shall, as between the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, be deemed to be a payment by the Company to or on account of the Senior Indebtedness; and no payments
or distributions of cash, property or securities to or for the benefit of the Securityholders pursuant to the subrogation provision of this Article, which would otherwise have been paid to the holders of Senior Indebtedness shall be deemed to be a
payment by the Company to or for the account of the Securities. It is understood that the provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities, on the one hand, and
the holders of the Senior Indebtedness, on the other hand. 
 Nothing contained in this Article or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Indebtedness, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the
Holders of the Securities the Principal of and interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and
creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Holder of any Security or the Trustee on his behalf from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy. 

Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of
Sections 7.01 and 7.02, and the holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such liquidation, dissolution, winding up, receivership, reorganization,
assignment or marshalling proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of the Securities,
for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article. 
 Section 11.04. Authorization by Securityholders.
Each Holder of a Security by his acceptance thereof authorizes the Trustee in his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes. 

  
 54 













 Section 11.05. Notice to Trustee. The Company shall give prompt written notice
to the Trustee and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of moneys to or by the Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article or
would end such prohibition. Regardless of anything to the contrary contained in this Article or elsewhere in this Indenture, the Trustee shall not be charged with knowledge of the existence of any Senior Indebtedness or of any default or event of
default with respect to any Senior Indebtedness or of any other facts which would prohibit the making of any payment of moneys to or by the Trustee or which would end such prohibition, unless and until the Trustee shall have received notice in
writing at its principal Corporate Trust Office to that effect signed by an Officer of the Company, or by a holder or agent of a holder of Senior Indebtedness or by the trustee under any indenture pursuant to which Senior Indebtedness shall be
outstanding, who shall have been certified by the Company or otherwise established to the reasonable satisfaction of the Trustee to be such holder or agent or trustee, and, prior to the receipt of any such written notice, the Trustee shall, subject
to Sections 7.01 and 7.02, be entitled to assume that no such facts exist; provided that if on a date at least three Business Days prior to the date upon which by the terms hereof any such moneys shall become payable for any purpose (including,
without limitation, the payment of the Principal of, or interest on any Security) the Trustee shall not have received with respect to such moneys the notice of prohibition provided for in this Section, then, regardless of anything herein to the
contrary, the Trustee shall have full power and authority to receive such moneys and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such
prior date. 
 Regardless of anything to the contrary herein, nothing shall prevent (a) any payment by the Company or the Trustee to
the Securityholders of amounts in connection with a redemption of Securities if (i) notice of such redemption has been given pursuant to Article 3 prior to the receipt by the Trustee of written notice of prohibition as aforesaid, and
(ii) such notice of redemption is given not earlier than 60 days before the redemption date, or (b) any payment by the Trustee to the Securityholders of amounts deposited with it pursuant to Sections 8.01, 8.05 or 8.06. 

The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee or agent on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness or a trustee or agent on behalf of any such holder. In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person
under this Article, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

  
 55 













 Section 11.06. Trustee’s Relation to Senior Indebtedness. The
Trustee and any agent of the Company or the Trustee shall be entitled to all the rights set forth in this Article with respect to any Senior Indebtedness which may at any time be held by it in its individual or any other capacity to the same extent
as any other holder of Senior Indebtedness and nothing in this Indenture shall deprive the Trustee or any such agent, of any of its rights as such holder. Nothing in this Article shall apply to claims of, or payments to, the Trustee under or
pursuant to 7.07. 
 With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Sections 7.01 and 7.02, the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to Holders of
Securities, the Company or any other Person moneys or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. 

Section 11.07. No Impairment of Subordination. No right of any present or future holder of any Senior Indebtedness to enforce
subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the
Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with.
