SECTION 2.01.     The aggregate principal amount of Securities which may be authenticated and delivered under this
Indenture is unlimited. 
 The Securities may be issued in one or more series up to the aggregate principal amount of Securities of that
series from time to time authorized by or pursuant to a Board Resolution, or pursuant to one or more indentures supplemental hereto, prior to the initial issuance of Securities of a particular series. Prior to the initial issuance of Securities of

all other Securities); 
 (2)    any limit upon the aggregate principal amount of Securities of that
series which may be authenticated and delivered under this Indenture (except for the Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of that series as provided in
Section 2.07 and Section 2.08); 
 (3)    the date or dates on which the principal of the
Securities of the series is payable;

(6)    the obligation, if any, of the Company to redeem or purchase the Securities of the series pursuant
to any sinking fund or analogous provisions (including payments made in cash in anticipation of future sinking fund obligations) or at the option of a holder thereof and the period or periods within which, the price or prices at which, and the terms
and conditions upon which, the Securities of the series shall be redeemed or purchased, in whole or in part, pursuant to such obligation; 

(7)    the form of the Securities of the series including the form of the Certificate of Authentication for

 (9)    if the Securities of the series shall be issued
in whole or in part in the form of a global Security or Securities, the type of global Security to be issued; the terms and conditions, if different from those contained in this Indenture, upon which such global Security or Securities may be
exchanged in whole or in part for certificated Securities; the depositary for such global Security or Securities; and the form of any legend or legends to be borne by any such global Security or Securities; 

(10)    the Person to whom any interest on a Security of the series shall be payable, if other than the
Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the regular record date for such interest; 

(11)    any addition to or change in the covenants set forth in Articles IV or X which applies to the
Securities of the series; 
 (12)    any addition to or change in the Events of Default which applies to
any Securities of the series and any change in the right of the Trustee or the requisite holders of such Securities to declare the principal amount thereof due and payable pursuant to Section 6.01; 

(13)    if a party other than Regions Bank is to act as Trustee for the Securities of such series, the name
and Corporate Trust Office of such party; 
 (14)    whether Securities of any series will be issued as
unrestricted Securities or restricted Securities, and, if issued as restricted Securities, the rule or regulation promulgated under the Securities Act of 1933, as amended, in reliance on which they will be sold; 

(15)    the terms and conditions, if any, upon which such Securities may be exchanged for or converted into
other securities issued by the Company or any other Person; and 
 (16)    any and all other terms with
respect to such series (which may be different from the provisions set forth in this Indenture so long as such different terms only apply to the series of Securities established thereby). 

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or
pursuant to any such Board Resolution or in any indentures supplemental hereto. 
 If any of the terms of the series are established
pursuant to a Board Resolution (and not a supplemental indenture), a copy thereof shall be delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series. 

All Securities of any one series need not be issued at one time and, unless otherwise provided in or pursuant to the Board Resolution and the
Officers’ Certificate referred to above or in such indenture supplemental hereto with respect to the Securities of a series, additional Securities of a series may be issued, at the option of the Company, without the consent of any
Securityholder, at any time and from time to time. 
 SECTION 2.02.     The Securities of any series and the
Trustee’s Certificate of Authentication to be borne by such Securities shall be substantially of the tenor and purport as set forth in one or more indentures supplemental hereto or as provided in a Board Resolution, and may have such letters,
numbers, CUSIP numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as the Company may deem appropriate, or as 

  
 7 












 
may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which Securities of that series may be listed,
or to conform to usage. 
 SECTION 2.03.    The Securities shall be issuable in the denominations of $2,000 or any
multiple of $1,000 in excess thereof, subject to Section 2.01(8). The Securities of a particular series shall bear interest payable on the dates and at the rate specified with respect to that series. The principal of and the interest on the
Securities of any series, as well as any premium thereon in case of redemption thereof prior to maturity, shall be payable in the coin or currency of the United States of America which at the time is legal tender for public and private debt, at the
office or agency of the Company maintained for that purpose in either the City of Monroe, State of Louisiana, the City of Broomfield, State of Colorado or the Borough of Manhattan, the City and State of New York, or, at the option of the Company, by
check in United States of America dollars mailed or delivered to the person in whose name such Security is registered. Each Security shall be dated the date of its authentication. 

Unless otherwise specified in the terms of the Securities of a series established as set forth in Section 2.01, the interest installment
on any Security which is payable, and is punctually paid or duly provided for, on any interest payment date for Securities of that series shall be paid to the person in whose name said Security (or one or more predecessor Securities) is registered
at the close of business on the regular record date for such interest installment. 
 Any interest on any Security which is payable, but is
not punctually paid or duly provided for, on any interest payment date for Securities of the same series (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered holder on the relevant regular record date
by virtue of having been such holder; and such Defaulted Interest shall be paid by the Company, at its election, as provided in clause (1) or clause (2) below: 

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

(2)    The Company may make payment of any Defaulted Interest on any Securities in any other lawful manner
not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant
to this clause, such manner of payment shall be deemed practicable by the Trustee. 

  
 8 












 The term “regular record date” as used in this Section with respect to any
interest payment date for the Securities of a series shall mean the record date set forth in the supplemental indenture entered into with respect to such series in accordance with Section 2.01. 

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

SECTION 2.04.     An Officer shall sign the Securities for the Issuer by manual, facsimile or PDF signature. If the
Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. 

Only such Securities of a series as shall bear thereon a certificate of authentication substantially in the form established for such series,
executed manually by an authorized signatory of the Trustee, or by any Authenticating Agent appointed by the Trustee with respect to such series, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such
certificate executed by the Trustee, or by any Authenticating Agent appointed by the Trustee with respect to such series, upon any Security of such series executed by the Company shall be conclusive evidence that the Security so authenticated has
been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of 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 executed by the Company to the Trustee for authentication, together with a written order of the Company for the authentication and
delivery of such Securities, signed by two Officers, and the Trustee in accordance with such written order shall authenticate and deliver such Securities. 

In authenticating Securities of any series and accepting the additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion of Counsel stating that the form and terms thereof have been established in conformity with the provisions of this
Indenture and that such Securities, when authenticated and delivered by the Trustee, will be duly authorized, executed and delivered and will constitute the legal, valid and binding obligations of the Company, enforceable against it in accordance
with their terms. 
 The Trustee shall not be required to authenticate any Securities of a series 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. 

SECTION 2.05.     (a) Securities of any series may be exchanged upon presentation thereof at the office or agency of
the Company designated for such purpose in any of the City of Monroe, State of Louisiana, the City of Broomfield, State of Colorado, or the Borough of Manhattan, the City and State of New York, for other Securities of such series of authorized
denominations, and for a like aggregate principal amount, upon payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, all as provided in this Section. In respect of any Securities so surrendered for exchange,
the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in exchange therefor the Security or Securities of the same series which the Securityholder making the exchange shall be entitled to receive, bearing
numbers not contemporaneously outstanding. 

  
 9 












 (b)    The Trustee is hereby appointed as the registrar (the
“Security Registrar”) for the purpose of registering securities and the transfer of securities as herein provided. The Company shall cause to be kept at the office or agency designated for such purpose in any of the City of Monroe, State
of Louisiana, the City of Broomfield, State of Colorado, or the Borough of Manhattan, the City and State of New York, or such other location designated by the Company a register or registers (herein referred to as the “Security Register”)
in which, subject to such reasonable regulations as it may prescribe, the Company shall register the Securities and the transfers of the Securities as in this Article provided. 

Upon surrender for transfer of any Security at the office or agency of the Company designated for such purpose in any of the City of Monroe,
State of Louisiana, the City of Broomfield, State of Colorado, or the Borough of Manhattan, the City and State of New York, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in the name of the
transferee or transferees a new Security or Securities of the same series as the Security presented for a like aggregate principal amount. 

All Securities presented or surrendered for exchange or registration of transfer, as provided in this Section, shall be accompanied (if so
required by the Company or the Security Registrar) by a written instrument or instruments of transfer, in form satisfactory to the Company or the Security Registrar, duly executed by the registered holder or by his duly authorized attorney in
writing. 
 (c)    No service charge shall be made for any exchange or registration of transfer of the Securities, or
issue of new Securities in case of partial redemption of any series, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, other than exchanges pursuant to Section 2.06, the
second paragraph of Section 3.03 and Section 9.04 not involving any transfer. 
 (d)    The Company shall not
be required (a) to issue, exchange or register the transfer of the Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of less than all the Outstanding
Securities of such series and ending at the close of business on the day of such mailing, nor (b) to register the transfer of or exchange any Securities of any series or portions thereof called for redemption. 

SECTION 2.06.    Pending the preparation of definitive Securities of any series, the Company may execute, and the Trustee
shall authenticate and deliver, temporary Securities (printed, lithographed or typewritten) of any authorized denomination, and substantially in the form of the definitive Securities in lieu of which they are issued, but with such omissions,
insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every temporary Security of any series shall be executed by the Company and be authenticated by the Trustee upon the same conditions
and in substantially the same manner, and with like effect, as the definitive Securities of such series. Without unnecessary delay the Company will execute and will furnish definitive Securities of such series and thereupon any or all temporary
Securities of such series may be surrendered in exchange therefor (without charge to the holders), at the office or agency of the Company designated for the purpose in any of the City of Monroe, State of Louisiana, the City of Broomfield, State of
Colorado, or the Borough of Manhattan, the City and State of New York, and the Trustee shall authenticate and such office or agency shall deliver in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities
of such series. Until so exchanged, the temporary Securities of such series shall be entitled to the same benefits under this Indenture as definitive Securities of such series authenticated and delivered hereunder.

SECTION 2.07.    In case any temporary or definitive Security shall become


  
 10 












 
mutilated or be destroyed, lost or stolen, the Company (subject to the next succeeding sentence) shall execute, and upon its request the Trustee (subject as aforesaid) shall authenticate and
deliver, a new Security of the same series bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen. In every case
the applicant for a substituted Security shall furnish to the Company and to the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of the applicant’s Security and of the ownership thereof. The Trustee may authenticate any such substituted Security and deliver the same
upon the written request or authorization of any officer of the Company. Upon the issue of any substituted Security, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. In case any Security which has matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the Company may,
instead of issuing a substitute Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security) if the applicant for such payment shall furnish to the Company and to the Trustee such security
or indemnity as they may require to save them harmless, and, in case of destruction, loss or theft, evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of such Security and of the ownership thereof. 

Every Security issued pursuant to the provisions of this Section in substitution for any Security which is mutilated, destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be found at any time, or be enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of the same series duly issued hereunder. All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities, and shall preclude (to the extent lawful) any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect
to the replacement or payment of negotiable instruments or other securities without their surrender. 
 SECTION
2.08.     All Securities surrendered for the purpose of payment, redemption, exchange or registration of transfer shall, if surrendered to the Company or any paying agent, be delivered to the Trustee for cancellation, or, if
surrendered to the Trustee, shall be canceled by it, and no Securities shall be issued in lieu thereof except as expressly required or permitted by any of the provisions of this Indenture. On request of the Company, the Trustee shall deliver to the
Company canceled Securities held by the Trustee. In the absence of such request the Trustee may destroy canceled Securities in accordance with its standard procedures and deliver a certificate of destruction to the Company. If the Company shall
otherwise acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation. 

SECTION 2.09.     Nothing in this Indenture or in the Securities, express or implied, shall give or be construed to
give to any person, firm or corporation, other than the parties hereto and the holders of the Securities, any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein
contained; all such covenants, conditions and provisions being for the sole benefit of the parties hereto and of the holders of the Securities. 

SECTION 2.10.     So long as any of the Securities of any series remain Outstanding there may be an Authenticating Agent
for any or all such series of Securities which the Trustee shall have the right to appoint. Said Authenticating Agent shall be authorized to act on behalf of the Trustee to 

  
 11 












 
authenticate Securities of such series issued upon exchange, transfer or partial redemption thereof, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall
be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. All references in this Indenture to the authentication of Securities by the Trustee shall be deemed to include authentication by an Authenticating Agent for such
series except for authentication upon original issuance or pursuant to Section 2.07 hereof. Each Authenticating Agent shall be acceptable to the Company and shall be a corporation which has a combined capital and surplus, as most recently
reported or determined by it, sufficient under the laws of any jurisdiction under which it is organized or in which it is doing business to conduct a trust business, and which is otherwise authorized under such laws to conduct such business and is
subject to supervision or examination by Federal or State authorities. If at any time any Authenticating Agent shall cease to be eligible in accordance with these provisions, it shall resign immediately. All fees and expenses of the Authenticating
Agent shall be paid by the Company. 
 Any Authenticating Agent may at any time resign by giving written notice of resignation to the
Trustee and to the Company. The Trustee may at any time (and upon request by the Company shall) terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon
resignation, termination or cessation of eligibility of any Authenticating Agent, the Trustee may appoint an eligible successor Authenticating Agent acceptable to the Company. Any successor Authenticating Agent, upon acceptance of its appointment
hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder as if originally named as an Authenticating Agent pursuant hereto. 

SECTION 2.11.     The Company in issuing Securities of any series shall use a “CUSIP” number and the Trustee
shall use the CUSIP number in notices of redemption or exchange as a convenience to the holders of the Securities of such series; provided, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP
number printed in the notice or on the Securities of such series, and that reliance may be placed only on the other identification numbers printed on the Securities of such series. 

SECTION 2.12.     Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payments of principal of (and premium, if any), and (subject to Section 2.03) interest
on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee, shall be affected by notice to the contrary. 

ARTICLE III. 
 REDEMPTION OF
SECURITIES AND SINKING FUND PROVISIONS 
 SECTION 3.01.     The Company may redeem the Securities of any series
issued hereunder on and after the dates and in accordance with the terms established for such series pursuant to Section 2.01 hereof. 

SECTION 3.02.     (a) In case the Company shall desire to exercise such right to redeem all or, as the case may be, a
portion of the Securities of any series in accordance with the right reserved so to do, the Company shall give notice of such redemption to holders of the Securities of such series to be redeemed and to the Trustee by mailing, first class postage
prepaid, a notice of such redemption not less than 10 days and not more than 60 days before the date fixed for redemption of that series to such holders at their last addresses as they shall appear upon the Security Register. Any notice which is
mailed in the manner herein provided shall be conclusively presumed to have been duly given, 

  
 12 












 
whether or not the registered holder receives the notice. In any case, failure duly to give such notice to the holder of any Security of any series designated for redemption in whole or in part,
or any defect in the notice, shall not affect the validity of the proceedings for the redemption of any other Securities of such series or any other series. In the case of any redemption of the Securities prior to the expiration of any restriction
on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with any such restriction. 

Each such notice of redemption shall specify the date fixed for redemption and the redemption price at which Securities of that series are to
be redeemed, and shall state that payment of the redemption price of such Securities to be redeemed will be made at the office or agency of the Company in any of the City of Monroe, State of Louisiana, the City of Broomfield, State of Colorado, or
the Borough of Manhattan, the City and State of New York, or, at the option of the Company, by check in United States of America dollars mailed or delivered to the person in whose name such Security is registered, or upon presentation and surrender
of such Securities, that interest accrued to the date fixed for redemption will be paid as specified in said notice, that from and after said date interest will cease to accrue and that the redemption is for a sinking fund, if such is the case. If
less than all the Securities of a series are to be redeemed, the notice to the holders of Securities of that series to be redeemed in whole or in part shall specify the particular Securities to be so redeemed. In case any Security is to be redeemed
in part only, the notice which relates to such Security shall state the portion of the principal amount thereof to be redeemed, and shall state that on and after the redemption date, upon surrender of such Security, a new Security or Securities of
such series in principal amount equal to the unredeemed portion thereof will be issued. 
 (b)    If less than all of
the Securities of a series are to be redeemed, the Company shall give the Trustee at least 5 days’ notice in advance of the date fixed for redemption as to the aggregate principal amount of the Securities of the series to be redeemed, and
thereupon the Trustee shall select, by lot or in such other manner as it shall deem appropriate and fair in its discretion and which may provide for the selection of a portion or portions (equal to the applicable minimum authorized denomination or
any multiple thereof) of the principal amount of such Securities of a denomination larger than the applicable minimum authorized denomination, the Securities to be redeemed and shall thereafter promptly notify the Company in writing of the numbers
of the Securities to be redeemed, in whole or in part. 
 The Company may, if and whenever it shall so elect, by delivery of instructions
signed on its behalf by one of its Officers, instruct the Trustee or any paying agent to call all or any part of the Securities of a particular series for redemption and to give notice of redemption in the manner set forth in this Section, such
notice to be in the name of the Company or its own name as the Trustee or such paying agent may deem advisable. In any case in which notice of redemption is to be given by any such paying agent, the Company shall deliver or cause to be delivered to,
or permit to remain with, such paying agent, as the case may be, such Security Registrar, transfer books or other records, or suitable copies or extracts therefrom, sufficient to enable the paying agent to give any notice by mail that may be
required under the provisions of this Section. 
 SECTION 3.03.     (a) Once notice of redemption is sent as above
provided, the Securities or portions of the Securities called for redemption become irrevocably due and payable on the redemption date at the redemption price. However, notice of redemption may, at the Company’s option and discretion, be
subject to one or more conditions precedent. On and after the redemption date, unless the Company defaults in the payment of the redemption price, interest shall cease to accrue on the Securities or portions of them called for redemption. If such
redemption is subject to satisfaction of one or more conditions precedent, in the Company’s discretion, the redemption date may be delayed until such 

  
 13 












 
time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied, or such
redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. Failure to give notice or any defect in
the notice to any Securityholder shall not affect the validity of the notice to any other Securityholder. 
 (b)    Upon
presentation of any Security of such series which is to be redeemed in part only, the Company shall execute and the Trustee shall authenticate and the office or agency where the Security is presented shall deliver to the holder thereof, at the
expense of the Company, a new Security or Securities of the same series, of authorized denominations in principal amount equal to the unredeemed portion of the Security so presented. 

SECTION 3.04.     The provisions of Sections 3.04, 3.05 and 3.06 shall be applicable to any sinking fund for the
retirement of the Securities of a series, except as otherwise specified as contemplated by Section 2.01 for Securities of such series. 

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a
“mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment”. If a sinking fund is provided
for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 3.05. Each sinking fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series. 
 SECTION 3.05.     The Company (1) may deliver
Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit the Securities of a series which have been redeemed either at the election of the Company or the holders pursuant to the terms of
such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of the Securities of such series, in each case in satisfaction of all or any part of any sinking fund payment with respect to Securities of
such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose
by the Trustee at the redemption price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 

SECTION 3.06.     Not less than 45 days prior to each sinking fund payment date for any series of Securities, the
Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by
delivering and crediting Securities of that series pursuant to Section 3.05 and the basis for such credit and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 3.02 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 3.02. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 3.03.

 SECTION
4.01.     The Company will duly and punctually pay or cause to be paid the principal of (and premium, if any) and interest on Securities of that series at the time and place and in the manner provided herein and established
with respect to such Securities. 
 SECTION 4.02.     So long as any series of Securities remain Outstanding, the
Company agrees to maintain an office or agency in any of the City of Monroe, State of Louisiana, the City of Broomfield, State of Colorado, or the Borough of Manhattan, the City and State of New York, with respect to each such series and at such
other location or locations as may be designated as provided in this Section 4.02, where (i) Securities of that series may be presented for payment, (ii) Securities of that series may be presented as hereinabove authorized for
registration of transfer and exchange, and (iii) notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be given or served. As to such office or agency in any of the City of Monroe, State
of Louisiana, the City of Broomfield, State of Colorado, or the Borough of Manhattan, the City and State of New York, the Company shall designate the required office or agency to be located in any of the City of Monroe, State of Louisiana, the City
of Broomfield, State of Colorado, or the Borough of Manhattan, the City and State of New York, for each series of the Securities, such designation to continue with respect to such office or agency until the Company shall, by written notice signed by
one of its Officers and delivered to the Trustee, designate some other office or agency for such purposes or any of them. 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, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, notices and demands. 

SECTION 4.03.     (a) If the Company shall appoint one or more paying agents for all or any series of the Securities,
other than the Trustee, the Company will cause each such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section, 

(1)    that it will hold all sums held by it as such agent for the payment of the principal of (and
premium, if any) or interest on the Securities of that series (whether such sums have been paid to it by the Company or by any other obligor on such Securities) in trust for the benefit of the persons entitled thereto; 

(2)    that it will give the Trustee notice of any failure by the Company (or by any other obligor on such
Securities) to make any payment of the principal of (and premium, if any) or interest on the Securities of that series when the same shall be due and payable; 

(3)    that it will, at any time during the continuance of any failure referred to in the preceding
paragraph (a)(2) above, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent; and 

(4)    that it will perform all other duties of paying agent as set forth in this Indenture. 

  
 15 












 (b)    If the Company shall act as its own paying agent with respect to
any series of Securities, it will on or before each due date of the principal of (and premium, if any) or interest on Securities of that series, set aside, segregate and hold in trust for the benefit of the persons entitled thereto a sum sufficient
to pay such principal (and premium, if any) or interest so becoming due on Securities of that series until such sums shall be paid to such persons or otherwise disposed of as herein provided and will promptly notify the Trustee of such action, or
any failure (by it or any other obligor on such Securities) to take such action. Whenever the Company shall have one or more paying agents for any series of Securities, it will, prior to each due date of the principal of (and premium, if any) or
interest on any Securities of that series, deposit with a paying agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the persons entitled to such principal,
premium or interest, and (unless such paying agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 

(c)    Anything in this Section to the contrary notwithstanding, (i) the agreement to hold sums in trust as provided
in this Section is subject to the provisions of Section 11.05, and (ii) the Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or direct any paying agent to
pay, to the Trustee all sums held in trust by the Company or such paying agent, such sums to be held by the Trustee upon the same terms as those upon which sums were held by the Company or such paying agent; and, upon such payment by any paying
agent to the Trustee, such paying agent shall be released from all further liability with respect to such money. 
 SECTION
4.04.     The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so that there shall at all times be a Trustee hereunder.

 SECTION 4.05.     The Company will not, while any of the Securities remain Outstanding, create, or suffer to be
created or to exist, any mortgage, lien, pledge, security interest or other encumbrance of any kind upon any property of any character of the Company whether now owned or hereafter acquired or upon any of the income or profits therefrom unless it
shall make effective provision whereby the Securities then Outstanding shall be secured by such mortgage, lien, pledge, security interest or other encumbrance equally and ratably with any and all obligations and indebtedness thereby secured so long
as any such obligations and indebtedness shall be so secured; provided, however, that nothing in this Section shall be construed to prevent the Company from creating, or from suffering to be created or to exist, any mortgages, liens, pledges,
security interests or other encumbrances, or any agreements, with respect to: 
 (1)    Purchase money
mortgages, or other purchase money liens, pledges or encumbrances of any kind upon property hereafter acquired by the Company, or mortgages, liens, pledges, security interests or other encumbrances of any kind existing on such property at the time
of the acquisition thereof, or conditional sales agreements or other title retention agreements with respect to any property hereafter acquired; provided, however, that no such mortgage, lien, pledge, security interest or other encumbrance, and no
such agreement, shall extend to or cover any other property of the Company; 
 (2)    Liens, pledges,
security interests, mortgages or other encumbrances of any kind on the shares of stock of a corporation which, when such liens, pledges, security interests, mortgages or other encumbrances arise, concurrently becomes a Subsidiary or liens, pledges,
security interests, mortgages or other encumbrances on all or substantially all of the assets of a corporation arising in connection with the purchase or acquisition thereof by the Company, provided that such lien or other security interest shall
not attach to any other assets of the Company; 

  
 16 












 (3)    Liens for taxes, assessments, governmental
charges or levies; pledges or deposits to secure obligations under worker’s compensation or unemployment insurance laws or similar legislation; pledges or deposits to secure performance in connection with bids, tenders, contracts, performance
bonds and other similar arrangements (other than contracts for the payment of money) or leases to which the Company is a party; deposits to secure public or statutory obligations of the Company; materialmen’s, mechanics’, carriers’,
workers’, repairmen’s or other like liens in the ordinary course of business, or deposits to obtain the release of such liens; deposits to secure surety and appeal bonds to which the Company is a party, other pledges or deposits for
similar purposes in the ordinary course of business; liens created by or resulting from any litigation or legal proceeding which at the time is currently being contested in good faith by appropriate proceedings; leases made, or existing on property
acquired, in the ordinary course of business; landlord’s liens under leases to which the Company is a party; zoning restrictions, easements, licenses, restrictions on the use of real property or minor irregularities in title thereto, which do
not materially impair the use of such property in the operation of the business of the Company or the value of such property for the purpose of such business; the lien of the trustee under any indenture (including this Indenture), liens encumbering
property or assets under construction arising from progress or partial payments; liens arising from the filing of UCC financing statements regarding leases or consignments; any interest or title of a lessor in the property subject to any capitalized
lease or operating lease; liens arising out of consignment or similar arrangements entered into in the ordinary course of business; and liens existing on March 31, 1994; 

(4)    Indebtedness assumed by the Company of the character specified in the first proviso of
Section 4.06 hereof; or 
 (5)    The replacement, extension or renewal of any mortgage, lien,
pledge, security interest or other encumbrance, or of any agreement, permitted by the foregoing clauses (1), (2), (3), (4), or the replacement, extension or renewal (without increase) of the indebtedness secured thereby. 

SECTION 4.06.     The Company will not, while any of the Securities remain Outstanding, consolidate with, or merge
into, or merge into itself, or sell or convey all or substantially all of its property to, any other Company unless the provisions of Article Ten hereof are complied with. 

If upon any such consolidation or merger, or sale or conveyance, any of the property of the Company owned by the Company prior thereto would
thereupon become subject to any mortgage, security interest, pledge or lien, the Company prior to such consolidation, merger, sale or conveyance will secure the Outstanding Securities, or cause the same to be secured, equally and ratably with the
other indebtedness or obligations secured by such mortgage, security interest, pledge or lien so long as such other indebtedness or obligations shall be so secured; provided, however, that the subjection of the property of the Company to any
mortgage, security interest, pledge or lien securing indebtedness of an Affiliate which is required to be assumed by the Company in connection with any merger or consolidation of such Affiliate shall be deemed excluded from the operation of this
Section and shall not require that any of the Securities be secured; and provided, further, that the subjection of property of the Company to any mortgage, security interest, pledge or lien of the character referred to in clauses (1), (2), (3), (4)
and (5) of Section 4.05 shall be deemed excluded from the operation of this Section and shall not require that any of the Securities be secured.

 ARTICLE V. 

SECURITYHOLDERS’ LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE 

Unless otherwise specified in the terms of the Securities of a series established as set forth in Section 2.01, the Company agrees to
comply with the terms of this Article V as long as the Securities of such series remain outstanding. 
 SECTION
5.01.     If requested, the Company will furnish or cause to be furnished to the Trustee (a) semi-annually, at least five Business Days before each Interest Payment Date, a list, in such form as the Trustee may
reasonably require, of the names and addresses of the holders of each series of Securities and (b) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list is furnished; provided, however, no such list need be furnished for any series for which the Trustee shall be the Security Registrar; and provided further, that no such
reports shall be required if all Securities of a series are held in global form by any securities depository, including the Depository Trust Company or its nominees or to any successor thereof. 

SECTION 5.02.     (a) The Trustee shall preserve, in as current a form as is reasonably practicable, all information
as to the names and addresses of the holders of Securities contained in the most recent list furnished to it as provided in Section 5.01 and as to the names and addresses of holders of Securities received by the Trustee in its capacity as
Security Registrar (if acting in such capacity). 
 (b)    The Trustee may destroy any list furnished to it as provided
in Section 5.01 upon receipt of a new list so furnished. 
 (c)    In case three or more holders of Securities of a
series (hereinafter referred to as “applicants”) apply in writing to the Trustee, and furnish to the Trustee reasonable proof that each such applicant has owned a Security for a period of at least six months preceding the date of such
application, and such application states that the applicant’s desire to communicate with other holders of Securities of such series or holders of all Securities with respect to their rights under this Indenture or under such Securities, and is
accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit, then the Trustee shall, within five Business Days after the receipt of such application, at its election, either 

(1)    afford to such applicants access to the information preserved at the time by the Trustee in
accordance with the provisions of subsection (a) of this Section, or 
 (2)    inform such
applicants as to the approximate number of holders of Securities of such series or of all Securities, as the case may be, whose names and addresses appear in the information preserved at the time by the Trustee, in accordance with the provisions of
subsection (a) of this Section, and as to the approximate cost of mailing to such Securityholders the form of proxy or other communication, if any, specified in such application. 

(d)    If the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the
written request of such applicants, mail to each holder of such series or of all Securities, as the case may be, whose name and address appears in the information preserved at the time by the Trustee in accordance with the provisions of subsection
(a) of this Section, a copy of the form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or provision for the payment, of
the reasonable expenses of mailing, unless within five days after such tender, the Trustee shall mail to such 

  
 18 












 
applicants and file with the Commission, together with a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary
to the best interests of the holders of Securities of such series or of all Securities, as the case may be, or would be in violation of applicable law. Such written statement shall specify the basis of such opinion. If said Commission, after
opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining one or more of such objections, said Commission
shall find, after notice and opportunity for hearing, that all the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all such Securityholders with reasonable promptness
after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application. 

(e)    Each and every holder of the Securities, by receiving and holding the same, agrees with the Company and the Trustee
that neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the holders of Securities in accordance with the
provisions of subsection (b) of this Section, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under said
subsection (b). 
 SECTION 5.03.     (a) The Company covenants and agrees to file with the Trustee, within 15 days
after the Company is required to file the same with the Commission, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as said Commission may from time to time by
rules and regulations prescribe) which the Company may be required to file with said Commission pursuant to Section 13, Section 14 or Section 15(d) of the Securities Exchange Act of 1934, as amended; or, if the Company is not required
to file information, documents or reports pursuant to any of such sections, then to file with the Trustee and said Commission, in accordance with the rules and regulations prescribed from time to time by said Commission, such of the supplementary
and periodic information, documents and reports which may be required pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, in respect of a security listed and registered on a national securities exchange as may be
prescribed from time to time in such rules and regulations. 
 (b)    The Company covenants and agrees to file with
Trustee and the Commission, in accordance with the rules and regulations prescribed from time to time by said Commission, such additional information, documents and reports with respect to compliance by the Company with the conditions and covenants
provided for in this Indenture as may be required from time to time by such rules and regulations. 
 (c)    The Company
covenants and agrees to, or cause the Trustee to, transmit by mail, first class postage prepaid, or reputable over-night delivery service which provides for evidence of receipt, to the Securityholders, as their names and addresses appear upon the
Security Register, within 30 days after the filing thereof with the Trustee, such summaries of any information, documents and reports required to be filed by the Company pursuant to subsections (a) and (b) of this Section as may be required by
rules and regulations prescribed from time to time by the Commission. 
 (d)    The Company covenants and agrees to
furnish to the Trustee within 135 days of each fiscal year in which any of the Securities are Outstanding, or on or before such other day in each calendar year as the Company and the Trustee may from time to time agree upon, a certificate from the
principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company’s compliance with all conditions and covenants under this Indenture. For purposes of this subsection (d), such
compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture.

 SECTION 5.04.     (a) On or before July 15 in each year in
which any Securities are Outstanding hereunder, the Trustee shall transmit by mail, first class postage prepaid, to the Securityholders, as their names and addresses appear upon the Security Register, a brief report dated as of the preceding
May 15, with respect to any of the following events which may have occurred within the previous twelve months (but if no such event has occurred within such period no report need be transmitted):

surrounding the making thereof) made by the Trustee (as such) which remain unpaid on the date of such report, and for the reimbursement of which it claims or may claim a lien or charge, prior to that of the Securities, on any property or funds held
or collected by it as Trustee if such advances so remaining unpaid aggregate more than 1/2 of 1% of the principal amount of the Securities outstanding on the date of such report; 

(4)    any change to the amount, interest rate, and maturity date of all other indebtedness owing by the
Company, or by any other obligor on the Securities, to the Trustee in its individual capacity, on the date of such report, with a brief description of any property held as collateral security therefor, except any indebtedness based upon a creditor
relationship arising in any manner described in paragraphs (2), (3), (4), or (6) of subsection (b) of Section 7.13; 

(5)    any change to the property and funds, if any, physically in the possession of the Trustee as such on
the date of such report; 
 (6)    any release, or release and substitution, of property subject to the
lien of this Indenture (and the consideration thereof, if any) which it has not previously reported; 

(7)    any additional issue of Securities which the Trustee has not previously reported; and 

(8)    any action taken by the Trustee in the performance of its duties under this Indenture which it has
not previously reported and which in its opinion materially affects the Securities or the Securities of any series, except any action in respect of a default, notice of which has been or is to be withheld by it in accordance with the provisions of
Section 6.07. 
 (b)    The Trustee shall transmit by mail, first class postage prepaid, to the Securityholders, as

such since the date of the last report transmitted pursuant to the provisions of subsection (a) of this Section (or if no such report has yet been so transmitted, since the date of execution of this Indenture), for the reimbursement of which it
claims or may claim a lien or charge prior to that of the Securities of any series on property or funds held or collected by it as Trustee, and which it has not previously reported pursuant to this subsection if such advances remaining unpaid at any
time aggregate more than 10% of the principal amount of the Securities of such series Outstanding at such time, such report to be transmitted within 90 days after such time.

series as and when the same shall become due and payable, whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to that series; provided, however, that
notwithstanding the foregoing, the Company’s failure to pay, if caused solely by a wire transfer malfunction or similar problem outside the Company’s control, shall not be deemed an Event of Default; 

(3)    failure on the part of the Company duly to observe or perform any other of the covenants or
agreements on the part of the Company with respect to that series contained in such Securities or otherwise established with respect to that series of the Securities pursuant to section 2.01 hereof or contained in this Indenture (other than a
covenant or agreement which has been expressly included in this Indenture solely for the benefit of one or more series of the Securities other than such series) for a period of 60 days after the date on which written notice of such failure,
requiring the same to be remedied and stating that such notice is a “Notice of Default” hereunder, shall have been given to the Company by the Trustee, by registered or certified mail, or to the Company and the Trustee by the holders of at
least 30% in principal amount of the Securities of that series at the time outstanding; provided that a notice of default may not be given with respect to any action taken, and reported publicly or to the holders, more than two years prior to such
notice of default 
 (4)    a decree or order by a court having jurisdiction in the premises shall have
been entered adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking liquidation or reorganization of the Company under the Federal Bankruptcy Code or any other similar applicable Federal or State law, and

period of 90 days; 
 (5)    the Company shall institute proceedings to be adjudicated a voluntary
bankrupt, or shall consent to the filing of a bankruptcy proceeding against it, or shall file a petition or answer or consent seeking liquidation or reorganization under the Federal Bankruptcy Code or any other similar applicable Federal or State
law, or shall consent to the filing of any such petition, or shall consent to the appointment on the ground of insolvency or bankruptcy of a receiver or custodian or liquidator or trustee or assignee in bankruptcy or insolvency of it or of its
property, or shall make an assignment for the benefit of creditors; or 
 (6)    any other Event of
Default provided in the supplemental indenture or Board Resolution under which such series of Securities is issued or in the form of Security for such series. 

(b)    In each and every such case, unless the principal of all the Securities of that series shall have already become
due and payable, either the Trustee or the holders of not less than 30% in aggregate principal amount of the Securities of that series then Outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by such
Securityholders), may declare the principal of all the Securities of that series to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything contained in this Indenture or
in the Securities of that series or established with respect to that series pursuant to Section 2.01 hereof to the contrary notwithstanding. 

(c)    The provisions of Section 6.01(b), however, are subject to the condition that if, at any time after the
principal of the Securities of that series shall have been so declared 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 that series and the principal of (and premium, if any, on) any and all Securities of that series which shall have become due otherwise
than by acceleration (with interest upon such principal and premium, if any, and, to the extent that such payment is enforceable under applicable law, upon overdue installments of interest, at the rate per annum expressed in Securities of that
series to the date of such payment or deposit) and the amount payable to the Trustee under Section 7.06, and any and all Defaults under the Indenture, other than the nonpayment of principal on the Securities of that series which shall not have
become due by their terms, shall have been remedied or waived as provided in Section 6.06 then and in every such case the holders of a majority in aggregate principal amount of the Securities of that series then Outstanding, determined in
accordance with Section 8.04, by written notice to the Company and to the Trustee, may rescind and annul such declaration and its consequences; but no such rescission and annulment shall extend to or shall affect any subsequent default, or
shall impair any right consequent thereon. 
 (d)    In case the Trustee shall have proceeded to enforce any right with
respect to the Securities of that series under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then
and in every such case the Company and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceedings had
been taken. 

  
 22 












 SECTION 6.02.     (a) The Company covenants that (1) in case
default shall be made in the payment of any installment of interest on any of the Securities of a series, or any payment required by any sinking or analogous fund established with respect to that series as and when the same shall become due and
payable, and such default shall have continued for a period of 30 Business Days, or (2) in case default shall be made in the payment of the principal of (or premium, if any, on) any of the Securities of a series when the same shall have become
due and payable, whether upon maturity of the Securities of a series or upon redemption or upon declaration or otherwise — then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Securities
of that series, the whole amount that then shall have become due and payable on all Securities of such series for principal (and premium, if any) or interest, or both, as the case may be, with interest upon the overdue principal (and premium, if
any) and (to the extent that payment of such interest is enforceable under applicable law) upon overdue installments of interest at the rate per annum expressed in the Securities of that series; and, in addition, thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee under Section 7.06. 

(b)    In the case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and
as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree,
and may enforce any such judgment or final decree against the Company or other obligor upon the Securities of that series and collect in the manner provided by law out of the property of the Company or other obligor upon the Securities of that
series wherever situated the moneys adjudged or decreed to be payable. 
 (c)    In case of any receivership,
insolvency, liquidation, bankruptcy, reorganization, readjustment, arrangement, composition or other judicial proceedings affecting the Company, any other obligor on such Securities, or the creditors or property of either, the Trustee shall have
power to intervene in such proceedings and take any action therein that may be permitted by the court and shall (except as may be otherwise provided by law) be entitled to file such proofs of claim and other papers and documents as may be necessary
or advisable in order to have the claims of the Trustee and of the holders of Securities of such series allowed for the entire amount due and payable by the Company or such other obligor under the Indenture at the date of institution of such
proceedings and for any additional amount which may become due and payable by the Company or such other obligor after such date, and to collect and receive any moneys or other property payable or deliverable on any such claim, and to distribute the
same after the deduction of the amount payable to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the holders of Securities of such series to make such
payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to such Securityholders, to pay to the Trustee any amount due it under Section 7.06. 

(d)    All rights of action and of asserting claims under this Indenture, or under any of the terms established with
respect to the Securities of that series, may be enforced by the Trustee without the possession of any such Securities, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for payment to the Trustee of any amounts due under Section 7.06, be for the ratable benefit of the holders of the
Securities of such series. 
 In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific
enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

  
 23 












 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of that series or the rights of any holder thereof or to authorize the Trustee to vote in respect of the
claim of any Securityholder in any such proceeding. 
 SECTION 6.03.     Any moneys collected by the Trustee
pursuant to Section 6.02 with respect to a particular series of Securities shall be applied in the order following, at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal (or premium,
if any) or interest, upon presentation of the several Securities of that series, and stamping thereon the payment, if only partially paid, and upon surrender thereof if fully paid: 

FIRST: To the payment of costs and expenses of collection and of all amounts payable to the Trustee under Section 7.06; 

SECOND: To the payment of the amounts then due and unpaid upon Securities of such series for principal (and premium, if any) and interest, in
respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest,
respectively; and 
 THIRD: To the payment of any surplus then remaining to the Company, or its successors and assigns, or to whomsoever may
be lawfully entitled thereto. 
 SECTION 6.04.     No holder of any Security of any series shall have any right by
virtue or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof with respect to Securities of such series specifying such Event of Default, as hereinbefore provided, and
unless also the holders of not less than 30% in aggregate principal amount of the Securities of such series then Outstanding, determined in accordance with Section 8.04, shall have made written request upon the Trustee to institute such action,
suit or proceeding in its own name as trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity, shall have failed to institute any such action, suit or proceeding and the Trustee shall not have received any direction inconsistent with such written notice during such 60-day period by the holders of not less than a majority in aggregate principal amount of the Securities of such series then Outstanding; it being understood and intended, and being expressly covenanted by the taker
and holder of every Security of such series with every other such taker and holder and the Trustee, that no one or more holders of Securities of such series shall have any right in any manner whatsoever by virtue or by availing of any provision of
this Indenture to affect, disturb or prejudice the rights of the holders of any other of such Securities, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in
the manner herein provided and for the equal, ratable and common benefit of all holders of Securities of such series. For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity. 
 Notwithstanding any other provisions of this Indenture, however, the
right of any holder of any Security to receive payment of the principal of (and premium, if any) and interest on such Security, as therein provided, on or after the respective due dates expressed in such Security (or in the case of redemption, on
the redemption date), or to institute suit for the enforcement of any such payment on or after such respective dates or redemption date, shall not be impaired or affected without the consent of such holder. 

  
 24 












 SECTION 6.05.     (a) All powers and remedies given by this Article
to the Trustee or to the Securityholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any others thereof or of any other powers and remedies available to the Trustee or the holders of Securities, by judicial
proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture or otherwise established with respect to such Securities. 

(b)    No delay or omission of the Trustee or of any holder of any of the Securities to exercise any right or power
accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of Section 6.04,
every power and remedy given by this Article or by law to the Trustee or to the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Securityholders. 

SECTION 6.06.     The holders of a majority in aggregate principal amount of the Securities of any series at the time
Outstanding, determined in accordance with Section 8.04, shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee
with respect to such series; provided, however, that such direction shall not be in conflict with any rule of law or with this Indenture, as determined by the Trustee, or unduly prejudicial to the rights of holders of Securities of any other series
at the time Outstanding, determined in accordance with Section 8.04, not parties thereto. Subject to the provisions of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith
shall, by a responsible officer or officers of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability. The holders of a majority in aggregate principal amount of the Securities of any series at the
time Outstanding, determined in accordance with Section 8.04, may on behalf of the holders of all of the Securities of that series waive any past default in the performance of any of the covenants contained herein or established pursuant to
Section 2.01 with respect to such series and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on, any of the Securities of that series as and when the same shall become due by the terms of
such Securities or a call for redemption of Securities of that series. Upon any such waiver, the default covered thereby shall be deemed to be cured and to cease to exist for all purposes of this Indenture and the Company, the Trustee and the
holders of the Securities of that series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

SECTION 6.07.     The Trustee shall, within 90 days after the occurrence of a default with respect to a particular
series, transmit by mail, first class postage prepaid, to the holders of Securities of that series, as their names and addresses appear upon the Security Register, notice of all defaults with respect to that series known to the Trustee, unless such
defaults shall have been cured before the giving of such notice (the term “defaults” for the purposes of this Section being hereby defined to be the events specified in subsections (1), (2), (3), (4), (5) and (6) of
Section 6.01(a), not including any periods of grace provided for therein and irrespective of the giving of notice provided for by subsection (3) of Section 6.01(a)); provided, that, except in the case of default in the payment of the
principal of (or premium, if any) or interest on any of the Securities of that series or in the payment of any sinking fund installment established with respect to that series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee, or a trust committee of directors and/or responsible officers, of the Trustee in good faith determine that the withholding of such notice is in the interests of the Securityholders of Securities of
that series; provided further, that in the case of any default of the character specified in Section 6.01(a)(3) with respect to Securities of such series no such notice to the holders of the Securities of that series shall be given until at
least 30 days after the occurrence thereof. 

  
 25 












 The Trustee shall not be deemed to have knowledge of any default, except (i) a default
under subsections (a)(1) or (a)(2) of Section 6.01 as long as the Trustee is acting as paying agent for such series of Securities or (ii) any default as to which the Trustee shall have received written notice or a Responsible Officer
charged with the administration of this Indenture shall have obtained actual knowledge. 
 SECTION 6.08.     All
parties to this Indenture agree, and each holder of any Securities by his or her acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not
apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of Securityholders, holding more than 10% in aggregate principal amount of the Outstanding Securities of any series, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security of such series, on or after the respective due dates expressed in such Security or established pursuant to this Indenture. 

SECTION 6.09.     Any Noteholder Direction provided by any Directing Holder must be accompanied by a Position
Representation, which representation, in the case of a Default Direction, shall be deemed repeated at all times until the resulting Event of Default is cured or otherwise ceases to exist or the Securities are accelerated. In addition, each Directing
Holder must, at the time of providing a Noteholder Direction, make a Verification Covenant. In any case in which the holder is The Depository Trust Company or its nominee, any Position Representation or Verification Covenant required hereunder shall
be provided by the beneficial owner of the Securities in lieu of The Depository Trust Company or its nominee. 
 If, following the delivery
of a Noteholder Direction, but prior to acceleration of the Securities, the Company determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and
provides to the Trustee evidence that the Company has filed papers with a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any
Event of Default that resulted from the applicable Noteholder Direction, the cure period with respect to such Event of Default shall be automatically stayed pending a final and non-appealable determination of
a court of competent jurisdiction on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Securities, the Company provides to the Trustee an Officers’ Certificate stating that a Directing Holder
failed to satisfy its Verification Covenant, the cure period with respect to any Event of Default that resulted from the applicable Noteholder Direction shall be automatically stayed pending satisfaction of such Verification Covenant. Any breach of
the Position Representation shall result in such holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such holder, the percentage of notes held by the remaining holders that provided such
Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Event of Default shall be deemed never to have occurred. 

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the Trustee during the
pendency of an Event of Default as the result of a bankruptcy or similar insolvency proceeding shall not require compliance with the foregoing paragraphs. 

  
 26 












 SECTION 6.10.    Any time period in this Indenture to cure any actual or
alleged default or Event of Default may be extended or stayed by a court of competent jurisdiction. 
 ARTICLE VII. 

CONCERNING THE TRUSTEE 
 SECTION
7.01.    (a) The Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing of all Events of Default with respect to Securities of that series which may have occurred,
shall undertake to perform with respect to Securities of such series such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants shall be read into this Indenture against the Trustee. In case an Event
of Default with respect to the Securities of a series has occurred (which has not been cured or waived), the Trustee shall exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b)    No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except that 
 (1)    prior to
the occurrence of an Event of Default with respect to the Securities of a series and after the curing or waiving of all such Events of Default with respect to that series which may have occurred: 

(i)    the duties and obligations of the Trustee shall with respect to Securities of such series be
determined solely by the express provisions of this Indenture, and the Trustee shall not be liable with respect to Securities of such series except for the performance of such duties and obligations as are specifically set forth in this Indenture,
and no implied covenants or obligations shall be read into this Indenture against that Trustee; and 

(ii)    in the absence of bad faith on the part of the Trustee, the Trustee may with respect to Securities
of such series conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the
case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of
this Indenture; 
 (2)    the Trustee shall not be liable for any error of judgment made in good faith by
a Responsible Officer or responsible officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 

(3)    the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in
good faith in accordance with the direction of the holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding relating to the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture with respect to the Securities of that series; and 

  
 27 












 (4)    None of the provisions contained in this
Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for
believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Indenture or adequate indemnity against such risk is not reasonably assured to it. 

SECTION 7.02.    Except as otherwise provided in Section 7.01: 

(a)    The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, approval, bond, security or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 

(b)    Any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by a Board
Resolution or an instrument signed in the name of the Company by any two Officers (unless other evidence in respect thereof is specifically prescribed herein); 

(c)    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 or suffered or omitted hereunder in good faith and in reliance thereon; 

(d)    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 Securityholders, pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities
which may be incurred herein or thereby; nothing herein contained shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default with respect to a series of Securities (which has not been cured or waived) to
exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs; 
 (e)    The Trustee shall not be liable for any action taken or omitted to be taken by it
in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 

(f)    The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, security, or other papers or documents, unless requested in writing so to do by the holders of not less than a majority in principal amount of the
Outstanding Securities of the particular series affected thereby (determined as provided in Section 8.04); provided, however, 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
costs, expenses or liabilities as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand; and 

  
 28 












 (g)    The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder. 

SECTION 7.03.    (a) The recitals contained herein and in the Securities (other than the Certificate of Authentication on
the Securities) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. 

(b)    The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. 

(c)    The Trustee shall not be accountable for the use by the Company of any of the Securities or the use or application
by the Company of the proceeds of such Securities, or for the use or application of any moneys paid over by the Trustee in accordance with any provision of this Indenture or established pursuant to Section 2.01, or for the use or application of
any moneys received by any paying agent other than the Trustee. 
 SECTION 7.04.    The Trustee or any paying agent or
Security Registrar, in its individual or any other capacity, may become the owner or pledgee of the Securities with the same rights it would have if it were not Trustee, paying agent or Security Registrar. 

SECTION 7.05.    Subject to the provisions of Section 11.05, all moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any moneys received
by it hereunder except such as it may agree with the Company to pay thereon. 
 SECTION 7.06.    (a) The Company
covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) for all
services rendered by it in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties hereunder of the Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel (including in-house counsel) and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith. The Company also covenants to indemnify the Trustee
(and its officers, agents, directors and employees) for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on the part of the Trustee and arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending itself against any claim of liability in the premises. 

(b)    The obligations of the Company under this Section to compensate and indemnify the Trustee and to pay or reimburse
the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior 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. 
 SECTION
7.07.    Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a


  
 29 












 
matter be proved or established prior to taking or suffering or omitting to take 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 Officers’ 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 to be taken by it under the provisions of this Indenture upon the faith thereof. 

SECTION 7.08.    The Trustee shall be disqualified only where such disqualification is required by Section 310(b) of
the Trust Indenture Act. 
 SECTION 7.09.    There shall at all times be a Trustee with respect to the Securities issued
hereunder which shall at all times be a corporation organized and doing business under the laws of the United States of America or any State or Territory thereof or of the District of Columbia, or a corporation or other person permitted to act as
trustee by the Commission, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $10 million, and subject to supervision or examination by Federal, State, Territorial, or District of
Columbia authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Company may not, nor may any person directly or indirectly controlling, controlled by, or under
common control with the Company, serve as Trustee. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect specified in
Section 7.10. 
 SECTION 7.10.    (a) The Trustee or any successor hereafter appointed, may at any time resign with
respect to the Securities of one or more series by giving written notice thereof to the Company and by transmitting notice of resignation by mail, first class postage prepaid, to the Securityholders of such series, as their names and addresses
appear upon the Security Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee with respect to Securities of such series by written instrument, in duplicate, executed by order of the Board of
Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such
notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to the Securities of such series, or any Securityholder of that series who has been a bona fide
holder of a Security or Securities for at least six months may, subject to the provisions of Section 6.08, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court
may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
 (b)    In
case at any time any of the following shall occur: 
   (1)    the Trustee shall fail to comply
with the provisions of subsection (a) of Section 310 of the Trust Indenture Act after written request therefor by the Company or by any Securityholder who has been a bona fide holder of a Security or Securities for at least six months, or

   (2)    the Trustee shall cease to be eligible in accordance with the provisions of
Section 7.09 and shall fail to resign after written request therefor by the Company or by any such Securityholder of Securities, or 

  
 30 












   (3)    the Trustee shall become incapable of
acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 
 then, in any such case, the Company may remove the Trustee with respect to all Securities and appoint a
successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of
Section 7.08, unless the Trustee’s duty to resign is stayed as provided herein, any Securityholder who has been a bona fide holder of a Security or Securities for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint
a successor trustee. 
 (c)    The holders of a majority in aggregate principal amount of the Securities of any series
at the time Outstanding may at any time remove the Trustee with respect to such series and appoint a successor trustee. 

(d)    Any resignation or removal of the Trustee and appointment of a successor trustee with respect to the Securities of
a series pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11. 

(e)    Any successor trustee appointed pursuant to this Section may be appointed with respect to the Securities of one or
more series or all of such series, and at any time there shall be only one Trustee with respect to the Securities of any particular series. 

SECTION 7.11.    (a) In case of the appointment hereunder of a successor trustee with respect to all Securities, every
such successor trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective
and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument transferring to such successor trustee all the rights, powers, and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor trustee all
property and money held by such retiring Trustee hereunder. 
 (b)    In case of the appointment hereunder of a
successor trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor trustee with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor trustee relates, (2) 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, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder


  
 31 












 
administered by any other such Trustee and that no Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; 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, such retiring Trustee shall with respect to the Securities of that or those series to which the appointment of such
successor trustee relates have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture, 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, to the extent contemplated by such supplemental indenture, the 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. 

(c)    Upon request of any such successor trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. 

(d)    No successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee
shall be qualified and eligible under this Article. 
 (e)    Upon acceptance of appointment by a successor trustee as
provided in this Section, the Company shall transmit notice of the succession of such trustee hereunder by mail, first class postage prepaid, to the Securityholders, as their names and addresses appear upon the Security Register. If the Company
fails to transmit such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be transmitted at the expense of the Company. 

SECTION 7.12.    Any corporation into which the Trustee may be merged or converted or with which it may be consolidated,
or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such securities. 

SECTION 7.13.    Subject to the provisions of subsection (b) of this Section, if the Trustee shall be or shall become
a creditor, directly or indirectly, secured or unsecured, of the Company within three months prior to a default, as defined in subsection (c) of this Section, or subsequent to such a default, then, unless and until such default shall be cured,
the Trustee shall set apart and hold in a special account for the benefit of the Trustee individually, the holders of the Securities and the holders of other indenture securities (as defined in subsection (c) of this Section) 

(1) an amount equal to any and all reductions in the amount due and owing upon any claim as such creditor in respect of
principal or interest, effected after the beginning of such three months’ period and valid as against the Company and its other creditors, except any such reduction resulting from the receipt or disposition of any property described in
paragraph (2) of this subsection, or from the exercise of any right of set-off which the Trustee could have exercised if a petition in bankruptcy had been filed by or against the Company upon the date of
such default; and 

  
 32 












 (2)    all property received by the Trustee in respect
of any claim as such creditor, either as security therefor, or in satisfaction or composition thereof, or otherwise, after the beginning of such three months’ period, or an amount equal to the proceeds of any such property, if disposed of,
subject, however, to the rights, if any, of the Company and its other creditors in such property or such proceeds. 

Nothing herein contained, however, shall affect the right of the Trustee 

(A)    to retain for its own account (i) payments made on account of any such claim by any person
(other than the Company) who is liable thereon, and (ii) the proceeds of the bona fide sale of any such claim by the Trustee to a third person, and (iii) distributions made in cash, securities, or other property in respect of claims filed
against the Company in bankruptcy or receivership or in a case for reorganization pursuant to the Federal Bankruptcy Code or applicable State law; 

(B)    to realize, for its own account, upon any property held by it as security for any such claim, if
such property was so held prior to the beginning of such three months’ period; 
 (C)    to realize,
for its own account, but only to the extent of the claim hereinafter mentioned, upon any property held by it as security for any such claim, if such claim was created after the beginning of such three months’ period and such property was
received as security therefor simultaneously with the creation thereof, and if the Trustee shall sustain the burden of proving that at the time such property was so received the Trustee had no reasonable cause to believe that a default, as defined
in subsection (c) of this Section, would occur within three months; or 
 (D)    to receive payment
on any claim referred to in paragraph (B) or (C), against the release of any property held as security for such claim as provided in such paragraph (B) or (C), as the case may be, to the extent of the fair value of such property. 

For the purposes of paragraphs (B), (C) and (D), property substituted after the beginning of such three months’ period for property held
as security at the time of such substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding any pre-existing claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim. 
 If the Trustee shall be required to account, the funds and property held in such
special account and the proceeds thereof shall be apportioned between the Trustee, the Securityholders and the holders of other indenture securities in such manner that the Trustee, the Securityholders and the holders of other indenture securities
realize, as a result of payments from such special account and payments of dividends on claims filed against the Company in bankruptcy or receivership or in a case for reorganization pursuant to the Federal Bankruptcy Code or applicable State law,
the same percentage of their respective claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from the Company of the funds and property in such special account and before crediting to the respective
claims of the Trustee, the Securityholders and the holders of other indenture securities dividends on claims filed against the Company in bankruptcy or receivership or in a case for reorganization pursuant to the Federal Bankruptcy Code or
applicable State law, but after crediting 

  
 33 












 
thereon receipts on account of the indebtedness represented by their respective claims from all sources other than from such dividends and from the funds and property so held in such special
account. As used in this paragraph, with respect to any claim, the term “dividends” shall include any distribution with respect to such claim in bankruptcy or receivership or in a case for reorganization pursuant to the Federal Bankruptcy
Code or applicable State law, whether such distribution is made in cash, securities, or other property, but shall not include any such distribution with respect to the secured portion, if any, of such claim. The court in which such bankruptcy,
receivership or case for reorganization is pending shall have jurisdiction (i) to apportion between the Trustee, the Securityholders and the holders of other indenture securities, in accordance with the provisions of this paragraph, the funds
and property held in such special account and the proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of this paragraph due consideration in determining the fairness of the distributions to be
made to the Trustee, the Securityholders and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held
in such special account or as security for any such claim, or to make a specific allocation of such distributions as between the secured and unsecured portions of such claims, or otherwise to apply the provisions of this paragraph as a mathematical
formula. 
 Any Trustee who has resigned or been removed after the beginning of such three months’ period shall be subject to the
provisions of this subsection (a) as though such resignation or removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such three months’ period, it shall be subject to the provisions of this
subsection (a) if and only if the following conditions exist: 
 (i)    the receipt of property or
reduction of claim which would have given rise to the obligation to account, if such Trustee had continued as trustee, occurred after the beginning of such three months’ period; and 

(ii)    such receipt of property or reduction of claim occurred within three months after such resignation
or removal. 
 (b)    There shall be excluded from the operation of subsection (a) of this Section a creditor
relationship arising from 
   (1)    the ownership or acquisition of securities issued under
any indenture, or any security or securities having a maturity of one year or more at the time of acquisition by the Trustee; 

  (2)    advances authorized by a receivership or bankruptcy court of competent jurisdiction, or
by this Indenture, for the purpose of preserving any property other than cash which shall at any time be subject to the lien, if any, of this Indenture or of discharging tax liens or other prior liens or encumbrances thereon, if notice of such
advance and of the circumstances surrounding the making thereof is given to the Securityholders at the time and in the manner provided in this Indenture; 

  (3)    disbursements made in the ordinary course of business in the capacity of trustee under
an indenture, transfer agent, registrar, custodian, paying agent, subscription agent, fiscal agent or depositary, or other similar capacity; 

  (4)    an indebtedness created as a result of services rendered or premises rented; or an
indebtedness created as a result of goods or securities sold in a cash transaction as defined in subsection (c) of this Section; 

  
 34 












   (5)    the ownership of stock or of other
securities of a Company organized under the provisions of Section 25(a) of the Federal Reserve Act, as amended, which is directly or indirectly a creditor of the Company; or 

  (6)    the acquisition, ownership, acceptance or negotiation of any drafts, bills of exchange,
acceptances or obligations which fall within the classification of self-liquidating paper as defined in subsection (c) of this Section. 

(c)    As used in this Section: 

  (1)    The term “default” shall mean any failure to make payment in full of the
principal of (or premium, if any) or interest upon any of the Securities or upon the other indenture securities when and as such principal (or premium, if any) or interest becomes due and payable. 

  (2)    The term “other indenture securities” shall mean securities upon which the
Company is an obligor (as defined in the Trust Indenture Act of 1939, as amended) outstanding under any other indenture (A) under which the Trustee is also trustee, (B) which contains provisions substantially similar to the provisions of
subsection (a) of this Section, and (C) under which a default exists at the time of the apportionment of the funds and property held in said special account. 

  (3)    The term “cash transaction” shall mean 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. 

  (4)    The term “self-liquidating paper” shall mean 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, manufacture, 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. 

  (5)    The term “Company” shall mean any obligor upon any of the Securities. 

ARTICLE VIII. 
 CONCERNING THE
SECURITYHOLDERS 
 SECTION 8.01.    Whenever in this Indenture it is provided that the holders of a majority or
specified percentage in aggregate principal amount of the Securities of a particular series may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact
that at the time of taking any such action the holders of such majority or specified percentage of that series have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such holders of the
Securities of that series in person or by agent or proxy appointed in writing. 
 If the Company shall solicit from the Securityholders of
any series any request, demand, authorization, direction, notice, consent, waiver or other action, the Company may, at its option, as 

  
 35 












 
evidenced by an Officers’ Certificate, fix in advance a record date for such series for the determination of Securityholders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other action, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given before or after the
record date, but only the Securityholders of record at the close of business on the record date shall be deemed to be Securityholders for the purposes of determining whether Securityholders of the requisite proportion of Outstanding Securities of
that series have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Securities of that series shall be computed as of the record date.
Any such authorization, agreement or consent by such Securityholders on the record date shall be deemed effective upon receipt. 
 SECTION
8.02.    Subject to the provisions of Section 7.01, proof of the execution of any instrument by a Securityholder (such proof will not require notarization) or his agent or proxy and proof of the holding by any person of any
of the Securities shall be sufficient if made in the following manner: 
 (a)    The fact and date of the execution by
any such person of any instrument may be proved in any reasonable manner acceptable to the Trustee. 
 (b)    The
ownership of the Securities shall be proved by the Security Registrar of such Securities or by a certificate of the Security Registrar thereof. 

(c)    The Trustee may require such additional proof of any matter referred to in this Section as it shall deem necessary.

 SECTION 8.03.    Prior to the due presentment for registration of transfer of any Security, the Company, the Trustee,
any paying agent and any Security Registrar may deem and treat the person in whose name such Security shall be registered upon the books of the Company as the absolute owner of such Security (whether or not such Security shall be overdue and
notwithstanding any notice of ownership or writing thereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.03) interest on
such Security and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the contrary. 

SECTION 8.04.    In determining whether the holders of the requisite aggregate principal amount of Securities of a
particular series have concurred in any direction, consent or waiver under this Indenture, Securities of that series which are owned by the Company or any other obligor on Securities of that series or by any Affiliate of the Company or any other
obligor on the Securities of that series shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such
direction, consent or waiver only Securities of such series which the Trustee actually knows are so owned shall be so disregarded. The Securities so owned which have been pledged in good faith may be regarded as Outstanding for the purposes of this
Section, if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not a person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any such other obligor. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. 

 

  
 36 












 SECTION 8.05.    At any time prior to (but not after) the evidencing to
the Trustee, as provided in Section 8.01, of the taking of any action by the holders of the majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection with such
action, any holder of a Security of that series which is shown by the evidence to be included in the Securities the holders of which have consented to such action may, by filing written notice with the Trustee, and upon proof of holding as provided
in Section 8.02, revoke such action so far as concerns such Security. Except as aforesaid any such action taken by the holder of any Security shall be conclusive and binding upon such holder and upon all future holders and owners of such
Security, and of any Security issued in exchange therefor, on registration of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the holders of a
majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the holders of all the
Securities of that series. 
 ARTICLE IX. 

SUPPLEMENTAL INDENTURES 
 SECTION
9.01.    In addition to any supplemental indenture otherwise authorized by this Indenture, the Company, when authorized by a Board Resolution, and the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto, without the consent of the Securityholders, for one or more of the following purposes; 

(a)    to evidence the succession of another corporation to the Company, and the assumption by any such successor of the
covenants of the Company contained herein or otherwise established with respect to the Securities; or 
 (b)    to add
to the covenants of the Company such further covenants, restrictions, conditions or provisions for the protection of the holders of the Securities of all or any series as the Board of Directors and the Trustee shall consider to be for the protection
of the holders of Securities of all or any series, and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions, conditions or provisions a default or an Event of Default with respect
to such series permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, however, that in respect of any such additional covenant, restriction, condition or provision such supplemental
indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such default or may limit the remedies
available to the Trustee upon such default or may limit the right of the holders of a majority in aggregate principal amount of the Securities of such series to waive such default; or 

(c)    to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture
which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to make such other provisions in regard to matters or questions arising under this indenture as shall not be inconsistent with the
provisions of this Indenture and shall not adversely affect the interests of the holders of the Securities of any series; or 

(d)    to change or eliminate any of the provisions of this Indenture, provided that any such change or elimination shall
become effective only when there is no Security Outstanding of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision. 

The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, and to make any further
appropriate agreements and stipulations which may be therein contained, but the Trustee shall not be obligated to enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise. 

  
 37 












 Any supplemental indenture authorized by the provisions of this Section may be executed by
the Company and the Trustee without the consent of the holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 9.02. 

SECTION 9.02.    With the consent (evidenced as provided in Section 8.01) of the holders of not less than a majority
in aggregate principal amount of the Securities of each series affected by such supplemental indenture or indentures at the time Outstanding, the Company, when authorized by a Board Resolution, and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the
rights of the holders of the Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Securities of any series, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without the consent of the holder of each Security so affected, or (ii) reduce the aforesaid percentage of the
Securities, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of each Security then Outstanding and affected thereby. 

Upon the request of the Company, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Securityholders required to consent thereto as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. 

It shall not be necessary for the consent of the Securityholders of any series affected thereby under this Section to approve the particular
form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 Promptly
after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Trustee shall transmit by mail, first class postage prepaid, a notice, setting forth in general terms the substance of
such supplemental indenture, to the Securityholders of all series affected thereby as their names and addresses appear upon the Security Register. Any failure of the Trustee to mail such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such supplemental indenture. 
 SECTION 9.03.    Upon the execution of any
supplemental indenture pursuant to the provisions of this Article or of Section 10.01, this Indenture shall, with respect to such series, be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations
of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the holders of Securities of the series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to
such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

SECTION 9.04.    Securities of any series, affected by a supplemental indenture, authenticated and delivered after the
execution of such supplemental indenture pursuant to the provisions of this Article or of Section 10.01, may bear a notation in form approved by the Trustee, provided such 

  
 38 












 
form meets the requirements of any exchange upon which such series may be listed, as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine,
new Securities of that series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by
the Trustee and delivered in exchange for the Securities of that series then Outstanding. 
 SECTION 9.05.    The
Trustee, subject to the provisions of Section 7.01, may receive an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article is authorized or permitted by, and conforms to, the terms of this
Article and that it is proper for the Trustee under the provisions of this Article to join in the execution thereof. 
 ARTICLE X. 

CONSOLIDATION, MERGER AND SALE 

SECTION 10.01.    Nothing contained in this Indenture or in any of the Securities shall prevent any consolidation or
merger of the Company with or into any other corporation or corporations (whether or not affiliated with the Company), or successive consolidations or mergers in which the Company or its successor or successors shall be a party or parties, or shall
prevent any sale, conveyance, transfer or other disposition of the property of the Company or its successor or successors as an entirety, or substantially as an entirety, to any other corporation (whether or not affiliated with the Company or its
successor or successors) authorized to acquire and operate the same; provided, however, the Company hereby covenants and agrees that, upon any such consolidation, merger, sale, conveyance, transfer or other disposition, (a) the due and punctual
payment of the principal of (premium, if any) and interest on all of the Securities of all series in accordance with the terms of each series, according to their tenor, and the due and punctual performance and observance of all the covenants and
conditions of this Indenture with respect to each series or established with respect to such series pursuant to Section 2.01 to be kept or performed by the Company, shall be expressly assumed, by supplemental indenture satisfactory in form to
the Trustee executed and delivered to the Trustee by the Company formed by such consolidation, or into which the Company shall have been merged, or by the corporation which shall have acquired such property and (b) the corporation or
corporations formed by such consolidation or into which the Company is merged or the Person or Persons which acquire by conveyance or transfer, or which lease, the properties and assets of the Company substantially as an entirety shall be a Person
or Persons organized and existing under the laws of the United States of America, any State thereof or the District of Columbia. 
 SECTION
10.02.    (a) In case of any such consolidation, merger, sale, conveyance, transfer or other disposition and upon the assumption by the successor corporation, by supplemental indenture, executed and delivered to the Trustee and
satisfactory in form to the Trustee, of the due and punctual payment of the principal of, premium, if any, and interest on all of the Securities of all series Outstanding and the due and punctual performance of all of the covenants and conditions of
this Indenture or established with respect to each series of the Securities pursuant to Section 2.01 to be performed by the Company with respect to each series, such successor corporation shall succeed to and be substituted for the Company,
with the same effect as if it had been named herein as the party of the first part, and thereupon the predecessor corporation shall be relieved of all obligations and covenants under this Indenture and the Securities. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the name of the Company or any other predecessor obligor on the Securities, any or all of the Securities issuable hereunder which theretofore shall not have been signed by
the Company and delivered to the Trustee; and, upon the order of such successor company, instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any securities which previously shall have been signed and delivered 

  
 39 












 
by the officers of the predecessor Company to the Trustee for authentication, and any Securities which such successor corporation thereafter shall cause to be signed and delivered to the Trustee
for that purpose. All the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such
Securities had been issued at the date of the execution hereof. 
 (b)    In case of any such consolidation, merger,
sale, conveyance, transfer or other disposition such changes in phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate. 

(c)    Nothing contained in this Indenture or in any of the Securities shall prevent the Company from merging into itself
or acquiring by purchase or otherwise all or any part of the property of any other corporation (whether or not affiliated with the Company). 

SECTION 10.03.    The Trustee, subject to the provisions of Section 7.01, may receive an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or other disposition, and any such assumption, complies with the provisions of this Article. 

ARTICLE XI. 
 SATISFACTION AND
DISCHARGE OF INDENTURE; 
 UNCLAIMED MONEYS 

SECTION 11.01.    If at any time: (a) the Company shall have delivered to the Trustee for cancellation all Securities
of a series theretofore authenticated (other than any Securities which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.07) and the Securities for whose payment money or Governmental
Obligations has theretofore been deposited in trust or segregated and held in trust by the Company (and thereupon repaid to the Company or discharged from such trust, as provided in Section 11.05) or (b) all such Securities of a particular
series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption, and the Company shall deposit or cause to be deposited with the Trustee as trust funds the entire amount in moneys or Governmental Obligations sufficient or a combination thereof, sufficient,
without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay at maturity or upon redemption all Securities of that series not
theretofore delivered to the Trustee for cancellation, including principal (and premium, if any) and interest due or to become due to such date of maturity or date fixed for redemption, as the case may be, and if the Company shall also pay or cause
to be paid all other sums payable hereunder with respect to such series by the Company, then this Indenture shall thereupon cease to be of further effect with respect to such series except for the provisions of Sections 2.05, 2.07, 4.02 and 7.10,
which shall survive until the date of maturity or redemption date, as the case may be, and Sections 7.06 and 11.05 which shall survive to such date and thereafter, and the Trustee, on demand of the Company and at the cost and expense of the Company,
shall execute proper instruments acknowledging satisfaction of and discharging this Indenture with respect to such series. 
 SECTION
11.02.    If at any time all such Securities of a particular series not heretofore delivered to the Trustee for cancellation or which have not become due and payable as described in Section 11.01 shall have been paid by the
Company by depositing irrevocably with the Trustee as trust funds moneys or an amount of Governmental Obligations sufficient to pay at maturity or upon redemption all such Securities of that series not theretofore delivered to the Trustee for
cancellation, 

  
 40 












 
including principal (and premium, if any) and interest due or to become due to such date of maturity or date fixed for redemption, as the case may be, and if the Company shall also pay or cause
to be paid all other sums payable hereunder by the Company with respect to such series, then after the date such moneys or Governmental Obligations, as the case may be, are deposited with the Trustee the obligations of the Company under this
Indenture with respect to such series shall cease to be of further effect except for the provisions of Sections 2.05, 2.07, 4.02, 7.06, 7.10 and 11.05 hereof which shall survive until such Securities shall mature and be paid. Thereafter, Sections
7.06 and 11.05 shall survive. 
 SECTION 11.03.    All moneys or Governmental Obligations deposited with the Trustee
pursuant to Sections 11.01 or 11.02 shall be held in trust and shall be available for payment as due, either directly or through any paying agent (including the Company acting as its own paying agent), to the holders of the particular series of the
Securities for the payment or redemption of which such moneys or Governmental Obligations have been deposited with the Trustee. 
 SECTION
11.04.    In connection with the satisfaction and discharge of this Indenture all moneys or Governmental Obligations then held by any paying agent under the provisions of this Indenture shall, upon demand of the Company, be paid
to the Trustee and thereupon such paying agent shall be released from all further liability with respect to such moneys or Governmental Obligations. 

SECTION 11.05.    Any moneys or Governmental Obligations deposited with any paying agent or the Trustee, or then held by
the Company, in trust for payment of principal of or premium or interest on the Securities of a particular series that are not applied but remain unclaimed by the holders of such Securities for two years after the date upon which the principal of
(and premium, if any) or interest on such Securities shall have respectively become due and payable, shall be repaid to the Company on May 31 of each year or (if then held by the Company) shall be discharged from such trust; and thereupon the
paying agent and the Trustee shall be released from all further liability with respect to such moneys or Governmental Obligations, and the holder of any of the Securities entitled to receive such payment shall thereafter, as an unsecured general
creditor, look only to the Company for the payment thereof. 
 ARTICLE XII. 

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS 

AND DIRECTORS 
 SECTION
12.01.    No recourse under or upon any obligation, covenant or agreement of this Indenture, or of any Security, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, stockholder,
officer or director, past, present or future as such, of the Company or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that this Indenture and the obligations issued hereunder are solely corporate obligations, and that no such personal liability
whatever shall attach to, or is or shall be incurred by, the incorporators, stockholders, officers or directors as such, of the Company or of any predecessor or successor corporation, or any of them, because of the creation of the indebtedness
hereby authorized, or under or by reason of the obligations, covenants or agreements contained in this Indenture or in any of the Securities or implied therefrom; and that any and all such personal liability of every name and nature, either at
common law or in equity or by constitution or statute, of, and any and all such rights and claims against, every such incorporator, stockholder, officer or director as such, because of the creation of the indebtedness hereby authorized, or under or
by reason of the obligations, covenants or agreements contained in this Indenture or in any of the Securities or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of such Securities.

 ARTICLE XIII. 

DEFEASANCE AND COVENANT DEFEASANCE 

SECTION 13.01.    The Company may, at its option by Board Resolution of the Company, at any time, with respect to the
Securities, elect to have either Section 13.02 or Section 13.03 be applied to all Outstanding Securities upon compliance with the conditions set forth below in this Article XIII. 

SECTION 13.02.    Upon the Company’s exercise under Section 13.01 of the option applicable to this
Section 13.02, the Company shall be deemed to have been discharged from its obligations with respect to all Outstanding Securities on the date the conditions set forth in Section 13.04 are satisfied (hereinafter, “defeasance”).
For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Securities, which shall thereafter be deemed to be “Outstanding” only for the
purposes of Section 13.05 and the other Sections of this Indenture referred to in clauses (A) and (B) below, and to have satisfied all their other obligations under such Securities and this Indenture insofar as such Securities are
concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the Company’s
obligations with respect to such Securities under Sections 2.05, 2.06, 2.07, 4.02, 4.03 and the Company’s rights under Section 3.01, (B) rights of Securityholders to receive payment of principal of, premium, if any, and interest on such
Securities and any rights of the Securityholders with respect to such amounts, (C) the rights, obligations and immunities of the Trustee under this Indenture and (D) this Article XIII. Subject to compliance with this Article XIII, the
Company may exercise its option under this Section 13.02 notwithstanding the prior exercise of its option under Section 13.03 with respect to the Securities. 

SECTION 13.03.    Upon the Company’s exercise under Section 13.01 of the option applicable to this
Section 13.03, the Company shall be released from its obligations under any covenant contained in Sections 4.05, 4.06, 5.03, 10.02 with respect to the Outstanding Securities on and after the date the conditions set forth below are satisfied
(hereinafter, “covenant defeasance”), and the Securities shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent, declaration or other act of Securityholders (and the consequences of
any thereof) in connection with such provisions, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Outstanding Securities, the Company
may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such provision, whether directly or indirectly, by reason of any reference elsewhere herein to any such provision or by reason of
any reference in any such provision to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01(a)(3), but, except as specified above, the remainder
of this Indenture and such Securities shall be unaffected thereby. 
 SECTION 13.04.    The following shall be the
conditions to application of either Section 13.02 or Section 13.03 to the Outstanding Securities: 

(a)    The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee
satisfying the requirements of Section 7.09 who shall agree to comply with the provisions of this Article XIII applicable to it) as trust funds in trust for the purpose of making the 

  
 42 












 
following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Securityholders of such Securities, at any time prior to the maturity of the Securities:
(A) money in an amount, or (B) Governmental Obligations which through the payment of interest and principal will provide, not later than one day before the due date of payment in respect of the Securities, money in an amount, or (C) a
combination thereof, sufficient, in the opinion of a certified public accountant (selected by the Company in its sole discretion) expressed in a written certification delivered to the Trustee, to pay and discharge the principal of (and premium, if
any, on) and interest on, the Outstanding Securities on the stated maturity (or redemption date, if applicable) of such principal (and premium, if any) or installment of interest; provided that the Trustee (or such other trustee) shall have been
irrevocably instructed in writing to apply such money or the proceeds of such Governmental Obligations to said payments with respect to the Securities. Before such a deposit, the Company may give to the Trustee, in accordance with Section 3.02,
a notice of their election to redeem all of the Outstanding Securities at a future date in accordance with Article Three, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the
foregoing. 
 (b)    No Default or Event of Default with respect to the Securities shall have occurred and be continuing
on the date of such deposit or at any time during the period ending on the 123rd day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 

(c)    Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under,
this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound. 

(d)    In the case of an election under Section 13.02, the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (x) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (y) since the date of this Indenture, there has been a change in the applicable federal income tax law, in
either case to the effect that, and based thereon such opinion shall confirm that, the Securityholders of the Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred. 

(e)    In the case of an election under Section 13.03, the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that the Securityholders of the Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 

(f)    The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that all conditions precedent provided for relating to either the defeasance under Section 13.02 or the covenant defeasance under Section 13.03 (as the case may be) have been complied with. 

SECTION 13.05.    Subject to the provisions of Section 11.05, all money and Governmental Obligations (including the
proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 13.05, the “Trustee”) pursuant to Section 13.04 in respect of the Outstanding Securities shall be held in trust
and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to
the Securityholders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law or to the extent the
Company acts as the Company’s Paying Agent. 

  
 43 












 The Company shall pay and indemnify the Trustee and (if applicable) its officers, directors,
employees and agents against any tax, fee or other charge imposed on or assessed against Governmental Obligations deposited pursuant to Section 13.04 or the principal and interest received in respect thereof other than any such tax, fee or
other charge which by law is for the account of the Securityholders of the Outstanding Securities. 
 Anything in this Article XIII to the
contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company’s request any money or Governmental Obligations held by it as provided in Section 13.04 which, in the opinion of a certified
public accountant (selected by the Company in its sole discretion) expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent
defeasance or covenant defeasance, as applicable, in accordance with this Article XIII. 
 SECTION 13.06.    If the
Trustee or any Paying Agent is unable to apply any money in accordance with Section 11.01 or 13.05 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then
the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01, 13.02 or 13.03, as the case may be, until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance therewith; provided, however, that if the Company makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Securityholders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.
