	 	SECTION 104.	Acts of Holders; Record Dates. 

 Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are
delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders
signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee
and the Company, if made in the manner provided in this Section. 
 The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or
writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date
of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 

The fact and date of the execution by any Person of any such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner that the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine. 
 The ownership of Securities shall be proved by the Security Register. 
 Any
request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in
exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 

The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled
to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company
may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If not set by the Company before


  
 -9-









 
the first solicitation of a Holder made by any Person in respect of any such matter referred to in the foregoing sentence, the record date for any such matter shall be the 30th day (or, if later,
the date of the most recent list of Holders required to be provided pursuant to Section 701) before the first solicitation. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on
such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to
the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any
action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be
construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set
forth in Section 106. 
 The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (ii) any request to institute proceedings referred to in
Section 507(2) or (iii) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on
such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder
unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a
new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in
this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant
to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106. 
 With respect to any record date set pursuant to this Section, the
party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice
of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration
Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially 

  
 -10-









 
designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the
foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 
 Without limiting the
foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do
so pursuant to such appointment with regard to all or any part of such principal amount. 
  

	 	SECTION 105.	Notices, Etc., to Trustee and Company. 

 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

 (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made,
given, furnished or filed in writing and delivered in person or mailed by first-class mail, postage prepaid, addressed to the Trustee at its Corporate Trust Office, or transmitted by facsimile transmission (confirmed by delivery in person) or mail
by first-class mail, postage prepaid, or by guaranteed overnight courier, or 
 (2) the Company by the Trustee or
by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the
first paragraph of this instrument, Attention: Corporate Counsel, or at any other address previously furnished in writing to the Trustee by the Company. 
 The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods,
provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate
shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion
elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s
reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The Company agrees to assume all risks arising out of the use of such electronic methods to
submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

	 	SECTION 106.	Notice to Holders; Waiver. 


Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice
by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
  

	 	SECTION 107.	Conflict with Trust Indenture Act.

this Indenture limits, qualifies or conflicts with the duties imposed by any of Sections 310 to 317, inclusive, of the Trust Indenture Act through operation of Section 318(c) thereof, such imposed duties shall control. 

Whenever this Indenture refers to a provision of the Trust Indenture Act, that provision is incorporated by reference in and made a part
of this Indenture. The Indenture shall also include those provisions of the Trust Indenture Act required to be included herein by the provisions of the Trust Indenture Reform Act of 1990. The following Trust Indenture Act terms used in this

provision of any Security which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity. No interest shall accrue for the period after that Interest Payment Date,

seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. 
 Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them
have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together
with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been
established by or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee
shall receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating, 
 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this
Indenture; 
 (2) if the terms of such Securities have been established by or pursuant to Board Resolution as
permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and

creditors’ rights and to general equity principles. 
 If such form or terms have been so established, the Trustee shall not be required to

acceptable to the Trustee. 

  
 -24-









 Each Security shall be dated the date of its authentication. 

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has
been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the
Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

  

	 	SECTION 304.	Temporary Securities. 


Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued
and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 

If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at
the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 
  

	 	SECTION 305.	Registration, Registration of Transfer and Exchange. 

 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment
being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities.
The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
 Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall


  
 -25-









 
execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations
and of like tenor and aggregate principal amount. 
 At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Security presented or
surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made for any
registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. 
 If the Securities of any series
(or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be)
during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such
mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

The provisions of Clauses (1) through (7) below shall apply only to Global Securities: 

(1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated
for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. 

(2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for
Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless
(A)

  
 -26-









 
such Depositary (i) has notified the Trustee in writing that it is unwilling or unable to continue as Depositary for such Global Security and the Company is unable to locate a qualified
successor or (ii) has ceased to be a clearing agency registered under the Exchange Act, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) there shall exist such
circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 301. 
 (3) Subject to Clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion
thereof shall be registered in such names as the Depositary for such Global Security shall direct. 
 (4) If any
Global Security is to be exchanged for other Securities or cancelled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Securities Registrar for exchange or cancellation as provided in this Article Three. If
any Global Security is to be exchanged for other Securities or cancelled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global Security, then either (i) such Global Security shall be so
surrendered for exchange or cancellation as provided in this Article Three or (ii) the principal amount thereof shall be reduced, or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or equal to the principal
amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Securities Registrar, whereupon the Trustee, in accordance with the Applicable
Procedures, shall instruct the Depositary or its authorized representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Security by the Depositary, accompanied by registration instructions, the
Trustee shall, subject to Section 305(2) and as otherwise provided in this Article Three, authenticate and deliver any Securities issuable in exchange for such Global Security (or any portion thereof) in accordance with the instructions of the
Depositary. The Trustee shall not be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be fully protected in relying on, such instructions. 

(5) The Depositary or its nominee, as the registered owner of a Global Security, shall be the Holder of such Global
Security for all purposes under this Indenture and the Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner’s beneficial interest in a
Global Security shall be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members. Neither the Trustee nor the Securities Registrar shall have any
liability in respect of any transfers effected by the Depositary. 
 (6) The rights of owners of beneficial
interests in a Global Security shall be exercised only through the Depositary and shall be limited to those established by law and agreements between such owners and the Depositary and/or its Agent Members. 

  
 -27-









 (7) Every Security authenticated and delivered upon registration of transfer
of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security,
unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

 If any mutilated Security is surrendered to the Trustee together with such security or indemnity as may be required by the Company or the Trustee to save each of them harmless, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

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

 

	 	SECTION 307.	Payment of Interest; Interest Rights Preserved. 

 Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security of any series which is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the 

  
 -28-









 
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 in respect of Securities of such
series, except that, unless otherwise provided in the Securities of such series, interest payable on the Stated Maturity of the principal of a Security shall be paid to the Person to whom principal is paid. The initial payment of interest on any
Security of any series that is issued between a Regular Record Date and the related Interest Payment Date shall be payable as provided in such Security or in the Board Resolution pursuant to Section 301 with respect to the related series of
Securities. 
 Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in Clause (1) or (2) below: 
 (1) The Company may
elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at
the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the
date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice, which notice shall be prepared by the Company and shall be acceptable to the Trustee, of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at
the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 
 (2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such
Securities of the series in respect of which interest is in default 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. 

  
 -29-









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

 

	 	SECTION 308.	Persons Deemed Owners. 


Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee
shall treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 307) any 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. 

None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership interests of a Security in global form, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall prevent the Company or Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by a
Depositary (or its nominee), as a Holder, with respect to such Security in global form or impair, as between such Depositary and owners of beneficial interests in such Security in global form, the operation of customary practices governing the
exercise of the rights of such Depositary (or its nominee) as Holder of such Security in global form. 
  

	 	SECTION 309.	Cancellation. 

 All
Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to
any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities
shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company
Order. 
  

	 	SECTION 310.	Computation of Interest. 


Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months. 

  
 -30-










	 	SECTION 311.	CUSIP Numbers. 

 The
Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice
may state no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 

ARTICLE FOUR 

SATISFACTION AND DISCHARGE 

 

	 	SECTION 401.	Satisfaction and Discharge of Indenture. 

 This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the

Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Securities which have become due and
payable) or to the Stated Maturity or Redemption Date, as the case may be; 
 (2) the Company has paid or caused
to be paid all other sums payable hereunder by the Company; and

	 	SECTION 402.	Application of Trust Money. 

 Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and
any premium and interest for whose payment such money has been deposited with the Trustee.

 -33-









 (8) any other Event of Default provided with respect to Securities of that
series. 
  

	 	SECTION 502.	Acceleration of Maturity; Rescission and Annulment. 

 If an Event of Default (other than an Event of Default specified in Section 501(5), 501(6) or 501(7)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then
in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are
Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders),
and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default specified in Section 501(5), 501(6) or 501(7) with respect to Securities of any series at the time
Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 
 If an Event of Default with respect to the Securities of any series at the time Outstanding occurs and is continuing, then the principal amount of (and premium, if any, on) and accrued interest on all the
Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall become immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder. 
 At any time after such a declaration of
acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount
of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay 
 (A) all overdue interest on all Securities of that series, 
 (B)
the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 

(C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed
therefor in such Securities, and 

  
 -34-









 (D) all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; 
 and 

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

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

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

(3) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series, and a
continuance of such default for a period of five days 
 the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of
the Holders of such Securities, the whole amount then due and payable on such Securities for principal, including any sinking fund payment, and any premium and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

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

  
 -35-









 
rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

  

	 	SECTION 504.	Trustee May File Proofs of Claim. 

 In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized (i) to file and
prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Securities in accordance with the terms thereof and to file such other papers or documents as may be necessary or advisable in
order to have the claims of the Trustee (including any claim for the reasonable compensation, expense, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and (ii) to
collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding
is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 
 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote
for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
  

	 	SECTION 505.	Trustee May Enforce Claims Without Possession of Securities. 

 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 

  
 -36-










	 	SECTION 506.	Application of Money Collected. 

 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of
principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under Section 607; 

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities
in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively;
and 
 THIRD: The balance, if any, to the Company. 

 

	 	SECTION 507.	Limitation on Suits. 


Subject to Section 508, no Holder of any Security of any series shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) such Holder has previously given written notice to the Trustee of a continuing Default with respect to the Securities of that series; 

(2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made
written request to the Trustee to institute proceedings in respect of such Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; 

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

  
 -37-










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

 Notwithstanding any other provision in this Indenture, the Holder of any Security of any series shall have the right, which is absolute and unconditional, to receive payment of the principal of and any
premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder. 
  

	 	SECTION 509.	Restoration of Rights and Remedies. 

 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
  

	 	SECTION 510.	Rights and Remedies Cumulative. 

 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred
upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

  

	 	SECTION 511.	Delay or Omission Not Waiver. 

 No delay or omission of the Trustee or of any Holder of any Securities of the related series to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be. 
  

	 	SECTION 512.	Control by Holders. 

 The
Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee, with respect to the Securities of such series, provided that 

  
 -38-









 (1) such direction shall not be in conflict with any rule of law or with
this Indenture, 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction, and 
 (3) subject to the provisions of Section 601, the Trustee shall
have the right to decline to follow such direction if a Responsible Officer or Responsible Officers of the Trustee shall, in good faith, determine that the proceeding so directed would be unjustly prejudicial to the Holders not joining in any such
direction or would involve the Trustee in personal liability. 
  

	 	SECTION 513.	Waiver of Past Defaults. 


The Holders of not less than a majority in principal amount of the Outstanding Securities of any series affected thereby may on behalf of
the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default 
 (1) in the payment of the principal of or any premium or interest on any Security of such series, or 
 (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured,
for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
  

	 	SECTION 514.	Undertaking for Costs. 


All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any
court to require such an undertaking or to make such an assessment in any suit instituted by the Trustee, a suit by a Holder pursuant to Section 508 or a suit by the holders of more than 10% in aggregate principal amount of Securities then
outstanding. 
  

	 	SECTION 515.	Waiver of Usury, Stay or Extension Laws. 

 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or


  
 -39-









 
advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted. 
 ARTICLE SIX 

THE TRUSTEE 
  

	 	SECTION 601.	Certain Duties and Responsibilities. 

 (1) Except during the continuance of an Event of Default, 
 (A)
the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(B) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such 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 (but need not confirm or investigate the accuracy of
mathematical calculations or other facts stated therein). 
 (2) In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his
or her own affairs. 
 (3) 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 
 (A) this Subsection shall not be construed to limit the effect of Subsection (1) of this Section; 
 (B) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

 (C) 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 pursuant to Section 512, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under this Indenture with respect to the Securities of such series; and 

  
 -40-









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

 

	 	SECTION 602.	Notice of Defaults. 


Within 90 days after the occurrence of any default hereunder with respect to Securities of any series, the Trustee shall give the Holders
of Securities of such series notice of such default hereunder known to a Responsible Officer of the Trustee, unless such default shall have been cured or waived; and provided, further, that in the case of any default of the character
specified in Section 501(a)(i) and Section 501(a)(iv) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days or 60 days, respectively, after the occurrence thereof. For the purpose
of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become a default. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the
Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which
the Trustee is entitled to rely exclusively on Officers’ Certificates). 
  

	 	SECTION 603.	Certain Rights of Trustee. 


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

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

(3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or
established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate or an Opinion of
Counsel, or both, which shall comply with Section 102; 

  
 -41-









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

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the
request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which might be incurred by
it in compliance with such request or direction; 
 (6) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee,
in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and
premises of the Company, personally or by agent or attorney; and 
 (7) 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. 
 (8) the Trustee shall not be deemed to have notice of any default or Event of Default unless a
Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities
and this Indenture; 
 (9) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; 

(10) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles
of officers authorized at such time to take specified actions pursuant to this Indenture; 
 (11) the Trustee
shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; and 

(12) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any
kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

  
 -42-










	 	SECTION 604.	Not Responsible for Recitals or Issuance of Securities. 

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

	 	SECTION 605.	May Hold Securities. 

 The
Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise
deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
  

	 	SECTION 606.	Money Held in Trust. 


Money held by the Trustee in trust hereunder 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 money received by it hereunder except as otherwise agreed with the Company. 
  

	 	SECTION 607.	Compensation and Reimbursement. 

 The Company agrees 
 (1) to pay to the Trustee from time to time
reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement
or advance as shall be determined to have been caused by its own negligence or willful misconduct; and 
 (3) to
indemnify the Trustee (which for purposes of this Section 607(3) shall include its officers, directors, employees and agents) for, and to hold it harmless against, any loss, claim, damage, liability or expense (including the reasonable
compensation and the expenses and disbursements of its agents and counsel) incurred without negligence or willful misconduct on its part, arising out of or in connection 

  
 -43-









 
with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. 
 This indemnification shall survive the termination of this Indenture or
the earlier resignation or removal of the Trustee. 
 To secure the Company’s payment obligations in this Section 607,
the Trustee shall have a lien senior to the Securities as to all money or property held or collected by the Trustee for any amount owing it or any predecessor Trustee pursuant to this Section 607, except such money or property held in trust for
the benefit of holders of particular Securities. The obligations of the Company under this Section 607 shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 501(a) occurs, such expenses and
compensation for services are intended to constitute expenses of administration under the Bankruptcy Reform Act of 1978 or any successor statute. 
  

	 	SECTION 608.	Conflicting Interests. 


If the Trustee for the Securities of any series issued hereunder has or shall acquire a conflicting interest within the meaning of the
Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Trust
Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series or a trustee under the Subordinated Debt Indenture, dated as of
February 15, 2007, between the Company and The Bank of New York Mellon, as Trustee; the Junior Subordinated Indenture, dated as of February 3, 1997, between the Company and The Bank of New York, as Trustee; and the Junior Subordinated
Indenture, dated as of February 13, 2004, between the Company and The Bank of New York, as Trustee. Nothing herein shall prevent the Trustee from filing with the Commission the application refered to in the penultimate paragraph of
Section 310(b) of the Trust Indenture Act. 
  

	 	SECTION 609.	Corporate Trustee Required; Eligibility. 

 There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee
shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has (or in the case of a corporation included in a bank holding company system, the related holding company has) a combined capital and surplus of at least
$50,000,000 and is a corporation organized and existing under the laws of the United States of America or of any state or territory thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers and subject to
supervision or examination by Federal, State, Territorial or District of Columbia authority. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then
for the purposes 

  
 -44-









 
of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its
most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article. 
  

	 	SECTION 610.	Resignation and Removal; Appointment of Successor. 

 No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 611. 
 The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

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

(1) the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder
who has been a bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall cease to be
eligible under Section 609 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or
control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case,
(A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a 

  
 -45-









 
successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of
such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office. 
  

	 	SECTION 611.	Acceptance of Appointment by Successor. 

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

  
 -46-









 
Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture
as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall, upon payment of any fees
and expenses due and owing to it hereunder with respect to such series, duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates. 
 Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
  

	 	SECTION 612.	Merger, Conversion, Consolidation or Succession to Business. 

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

  

	 	SECTION 613.	Preferential Collection of Claims Against Company. 

 If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the
collection of claims against the Company (or any such other obligor). 

  
 -47-










	 	SECTION 614.	Appointment of Authenticating Agent. 

 The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such
reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in
this Section. 
 Any corporation into which an Authenticating Agent may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust
business of an Authenticating Agent, by sale or otherwise, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the
part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or
upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company
and shall give notice of such appointment in the manner provided in Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible
under the provisions of this Section. 

  
 -48-









 The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section. 
 If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

 Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held accountable by

 The
Company shall file with the Trustee and the Commission, and transmit to Holders, copies of such information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in the
manner provided pursuant to such Act; provided that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within
15 days after the same is filed with the Commission. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

 (9) to cure any ambiguity, to correct or
supplement any provision herein which may be defective or inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Indenture, provided that such action pursuant to
this Clause (9) shall not adversely affect the interests of the Holders of Securities of any series. 
  

	 	SECTION 902.	Supplemental Indentures With Consent of Holders. 

 With the consent of the Holders of not less than 66 2/3% in principal amount of the Outstanding Securities of each series affected by such supplemental indenture, by Act of said Holders delivered to the
Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of
the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby, 
 (1) change the Stated Maturity of the principal of, or any
installment of principal of or interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount
Security or any other Security which would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502, or change any Place of Payment where, or the coin or currency in which, any Security or any

of this Indenture with respect to the subordination of the Securities in a manner adverse to Holders, or 
 (2)

not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section and Section 1008, or the
deletion of this proviso, in accordance with the requirements of Sections 611 and 901(8). 
 A supplemental indenture which changes or
eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with
respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. 
 It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the
substance thereof. 
  

	 	SECTION 903.	Execution of Supplemental Indentures. 

 In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall

that all conditions herein provided for relating to such action have been complied with. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities
under this Indenture or otherwise. 
  

	 	SECTION 904.	Effect of Supplemental Indentures. 

 Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all
purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 
  

	 	SECTION 905.	Conformity with Trust Indenture Act.

by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture
may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series.

 ARTICLE TEN 
 COVENANTS 
  

	 	SECTION 1001.	Payment of Principal, Premium and Interest. 

 The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in
accordance with the terms of the Securities and this Indenture. 
  

	 	SECTION 1002.	Maintenance of Office or Agency. 

 The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that
series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 The Company may also
from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
  

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

 If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the
Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee in writing of its action or failure so to act. 
 Whenever
the Company shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such
amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of its action or failure so to act. 

  
 -55-









 The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act
applicable to it as a Paying Agent; (2) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written
request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series; (3) hold all sums held by it for the payment of the principal of (and premium, if any) or
interest on the Securities of a series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; and (4) give the Trustee notice of any default by the
Company (or any other obligor upon such Securities) in the making of any payment of principal (and premium, if any) or interest in respect of any Security of any series. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee
all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with respect to such money. 
 Any money deposited with
the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in
the Borough of Manhattan, the City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company. 
  

	 	SECTION 1004.	Statement by Officers as to Default. 

 The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate covering the preceding calendar year,
stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance or observance of any of the terms, 

  
 -56-









 
provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such
defaults and the nature and status thereof of which they may have knowledge. 
 The Company shall deliver to the Trustee, as
soon as possible and in any event within 30 days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’
Certificate setting forth the details of such Event of Default and the action which the Company proposes to take with respect thereto. 
  

	 	SECTION 1005.	Existence. 

 Subject to
Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required
to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders. 
  

	 	SECTION 1006.	Maintenance of Properties. 


The Company will cause all properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be
necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of
any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders. 

 

	 	SECTION 1007.	Payment of Taxes and Other Claims. 

 The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or
any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any
Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by
appropriate proceedings.

	 	SECTION 1008.	Waiver of Certain Covenants. 

 Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply
with any term, provision or condition set forth in any covenant provided pursuant to Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such series or in Section 1005, if before the time for such compliance the Holders of
at least 66 2/3% in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver
shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision
or condition shall remain in full force and effect. 
  

	 	SECTION 1009.	Calculation of Original Issue Discount. 

 For each year during which any Securities that were issued with original issue discount are Outstanding, the Company shall furnish to each Paying Agent in a timely fashion such information as may be
reasonably requested by each Paying Agent in order that each Paying Agent may prepare the information which it is required to report for such year on Internal Revenue Service Forms 1096 and 1099 pursuant to Section 6049 of the Internal Revenue
Code of 1986, as amended. Such information shall include the amount of original issue discount includible in income for each $1,000 of principal amount at Stated Maturity of outstanding Securities during such year. 

ARTICLE ELEVEN 

REDEMPTION OF SECURITIES 

 

	 	SECTION 1101.	Applicability of Article. 


Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 301 for such Securities) in accordance with such form of Security and this Article; provided, however, that if any provision of any such form of Security shall conflict with any provision
of this Article, the provision of such form of Security shall govern. Except as otherwise set forth in the form of Security for such series, such Security of a series shall be subject to partial redemption only in the amount of $1,000 or any
integral multiples thereof. 
  

	 	SECTION 1102.	Election to Redeem; Notice to Trustee. 

 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. In case of any

applicable, of the tenor of the Securities to be redeemed and provide the additional information required to be included in the notice or notices contemplated by Section 1104. In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 

 

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

 If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed), the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, pro rata, by lot or by such method as the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of a portion of the principal amount of any Security of such series all in accordance with the procedures of the Depositary, provided that the unredeemed portion of the principal amount of
any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee or by the Depositary, as applicable, from the Outstanding Securities of
such series and specified tenor not previously called for redemption in accordance with the preceding sentence. 
 For all
purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of

(2) the Redemption Price, 
 (3) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such
Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be
redeemed, 

  
 -59-









 (4) that on the Redemption Date the Redemption Price will become due and
payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 
 (5) the place or places where each such Security is to be surrendered for payment of the Redemption Price, 
 (6) that the redemption is for a sinking fund, if such is the case, 

(7) CUSIP numbers, if any, and 
 (8) such other provisions as may be required in respect of the terms of a particular series of Securities. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request and provision to the Trustee by the Company of the notice
information, by the Trustee in the name and at the expense of the Company and shall be irrevocable. 
  

	 	SECTION 1105.	Deposit of Redemption Price. 

 Prior to 10:00 a.m., New York City time, on the Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that
date. 
  

	 	SECTION 1106.	Securities Payable on Redemption Date. 

 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after
such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated
Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the
provisions of Section 307. 
 If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

	 	SECTION 1107.	Securities Redeemed in Part. 

 Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered. 
 ARTICLE TWELVE 

SINKING FUNDS 
  

	 	SECTION 1201.	Applicability of Article. 


The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise
specified as contemplated by Section 301 for such Securities. 
 The minimum amount of any sinking fund payment provided
for by the terms of any Securities is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an “optional
sinking fund payment”. If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities as provided for by the terms of such Securities. 
  

	 	SECTION 1202.	Satisfaction of Sinking Fund Payments with Securities. 

 The Company (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed
either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any
sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 

  
 -61-










	 	SECTION 1203.	Redemption of Securities for Sinking Fund. 

 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 such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to be satisfied by payment of cash in the currency in which the Securities of such series are payable (except as provided
pursuant to Section 301) and the portion thereof, if any, that is to be satisfied by delivering and crediting Securities pursuant to Section 1202 and will also deliver to the Trustee any Securities to be so delivered. Such Officers’
Certificate shall be irrevocable and upon its delivery the Company shall be obligated to make the cash payment or payments therein referred to, if any, on or before the succeeding sinking fund payment date. In the case of the failure of the Company
to deliver such Officers’ Certificate (or, as required by this Indenture, the Securities and coupons, if any, specified in such Officers’ Certificate) by the due date therefor, the sinking fund payment due on the succeeding sinking fund
payment date for such series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of the Securities of such series subject to a mandatory sinking fund payment without the right to deliver or credit securities as
provided in Section 1202 and without the right to make the optional sinking fund payment with respect to such series at such time. 
 Any sinking fund payment or payments (mandatory or optional) made in cash plus any unused balance of any preceding sinking fund payments made with respect to the Securities of any particular series shall
be applied by the Trustee (or by the Company if the Company is acting as its own Paying Agent) on the sinking fund payment date on which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund
payment date immediately following the date of such payment) to the redemption of Securities of such series at the Redemption Price specified in such Securities with respect to the sinking fund. Any sinking fund moneys not so applied or allocated by
the Trustee (or, if the Company is acting as its own Paying Agent, segregated and held in trust by the Company as provided in Section 1003) for such series and together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 1203. Any and all sinking fund moneys with respect to the Securities of any particular series held by the Trustee (or if the Company is acting as its own Paying Agent, segregated and held in trust
as provided in Section 1003) on the last sinking fund payment date with respect to Securities of such series and not held for the payment or redemption of particular Securities of such series shall be applied by the Trustee (or by the Company
if the Company is acting as its own Paying Agent), together with other moneys, if necessary, to be deposited (or segregated) sufficient for the purpose, to the payment of the principal of the Securities of such series at Maturity. The Trustee shall
select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 1106. On or before each sinking fund payment date, the Company shall pay to the Trustee
(or, if the Company is acting as its own Paying Agent, the Company shall segregate and hold in trust as provided in Section 1003) in cash a sum in the currency in which Securities of such series are payable (except as provided pursuant to
Section 301) equal to the principal (and premium, if any) and any interest (including any Additional Interest) accrued to the Redemption Date for Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this
Section 1203. 

  
 -62-









 Neither the Trustee nor the Company shall redeem any Securities of a series with sinking
fund moneys or mail any notice of redemption of Securities of such series by operation of the sinking fund for such series during the continuance of a default in payment of interest, if any, on any Securities of such series or of any Event of
Default with respect to the Securities of such series, except that if the notice of redemption shall have been provided in accordance with the provisions hereof, the Trustee (or the Company, if the Company is then acting as its own Paying Agent)
shall redeem such Securities if cash sufficient for that purpose shall be deposited with the Trustee (or segregated by the Company) for that purpose in accordance with the terms of this Article Twelve. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default shall occur and any moneys thereafter paid into such sinking fund shall, during the continuance of such default or Event of Default, be held as security for the payment of
the Securities and coupons, if any, of such series; provided however, that in case such default or Event of Default shall have been cured or waived herein, such moneys shall thereafter be applied on the next sinking fund payment date for the
Securities of such series on which such moneys may be applied pursuant to the provisions of this Section 1203.

	 	SECTION 1301.	Company’s Option to Effect Defeasance or Covenant Defeasance. 

 The Company may elect, at its option at any time, to have Section 1302 or Section 1303 applied to any Securities or any series of Securities, as the case may be, designated pursuant to
Section 301 as being defeasible pursuant to such Section 1302 or 1303, in accordance with any applicable requirements provided pursuant to Section 301 and upon compliance with the conditions set forth below in this Article. Any such
election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. 
  

	 	SECTION 1302.	Defeasance and Discharge. 


Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the
case may be, the Company shall be deemed to have been discharged from its obligations with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust 

  
 -63-









 
fund described in Section 1304 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due,
(2) the Company’s obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to
compliance with this Article, the Company may exercise its option (if any) to have this Section applied to any Securities or any series of Securities notwithstanding the prior exercise of its option (if any) to have Section 1303 applied to such
Securities. 
  

	 	SECTION 1303.	Covenant Defeasance. 


Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the
case may be, (1) the Company shall be released from its obligations under Section 1008, and any covenants provided pursuant to Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such Securities and (2) the
occurrence of any event specified in Sections 501(a)(iv) (with respect to Section 1008 and any such covenants provided pursuant to Section 301(18), 901(2) or 901(7)) and 501(b)(vi) shall be deemed not to be or result in an Event of
Default, in each case with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant
Defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case
of Section 501(b)(v)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of
this Indenture and such Securities shall be unaffected thereby. 
  

	 	SECTION 1304.	Conditions to Defeasance or Covenant Defeasance. 

 The following shall be the conditions to the application of Section 1302 or Section 1303 to any Securities or any series of Securities, as the case may be: 

(1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which
satisfies the requirements contemplated by Section 609 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for,
and dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their
terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a direct obligation of the
United 

  
 -64-









 
States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an
agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable
at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in Clause
(x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that
(except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the
specific payment of principal or interest evidenced by such depositary receipt. 
 (2) In the event of an
election to have Section 1302 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such
opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to
Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 

(3) In the event of an election to have Section 1303 apply to any Securities or any series of Securities, as the case
may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be
effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur. 

(4) The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that neither such
Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 

(5) No event which is, or after notice or lapse of time or both would become, an Event of Default
with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 501(a)(1), (a)(2) and (a)(3), at any time during the period ending
on the 90th day after the date of such deposit or, if
longer, ending on the day following the expiration of the longest preference period applicable to the Company in respect of such deposit (it being understood that the condition in this clause is a condition subsequent and shall not be deemed
satisfied until the expiration of such period). 

  
 -65-









 (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to
have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 
 (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is
bound. 
 (8) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit
constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration thereunder. 

(9) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating
that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
  

	 	SECTION 1305.	Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. 


Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 1304
in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting
as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other
funds except to the extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of
the Holders of Outstanding Securities. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or
pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 1304 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to
such Securities.

	 	SECTION 1306.	Reinstatement. 

 If the
Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 1302 or 1303 shall be revived and reinstated as though no deposit had occurred pursuant to
this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1305 with respect to such Securities in accordance with this Article; provided,
however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.
