theretofore deposited with the Trustee or any Paying Agent (other than the Company) in trust or set aside and segregated and held in trust by the Company (if the Company shall act as its own Paying Agent) for the Holders of such Debt Securities;
provided, however, that if such Debt Securities are to be redeemed prior to their Stated Maturity, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made; 

(iii) Debt Securities, except to the extent provided in Section 15.2, with respect to which the Company has effected defeasance

 (iv) Debt Securities that have been converted or exchanged for
other securities; and

which other Debt Securities have been authenticated and delivered pursuant to this Indenture, other than any such Debt Securities in respect of which there shall have been presented to the Trustee proof satisfactory to it that such Debt Securities
are held by a bona fide purchaser in whose hands such Debt Securities are valid obligations of the Company; 
 provided, however, that, in
determining whether the Holders of the requisite principal amount of Debt Securities Outstanding have performed any Act hereunder, Debt Securities owned by the Company or any other obligor upon the Debt Securities or any Affiliate of the Company or
of such other obligor shall be disregarded and deemed not to be Outstanding (provided that, in connection with any offer by the Company or any obligor to purchase Debt Securities, Debt Securities tendered by a Holder shall be deemed to be
Outstanding until the date of purchase), except that, (i) in determining whether the Trustee shall be protected in conclusively relying upon any such Act, only Debt Securities which a Responsible Officer of the Trustee actually knows to be so
owned shall be so disregarded and (ii) the foregoing shall not apply at any time when all of the Outstanding Debt Securities are owned by the Company, the Trustee and/or any such Affiliate. Debt Securities so owned which have been pledged in
good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to act with respect to such Debt Securities and that the pledgee is not the Company or any other obligor upon the Debt
Securities or any Affiliate of the Company or of such other obligor. In determining whether the Holders of the requisite principal amount of Outstanding Debt Securities have performed any Act hereunder, the principal amount of a Discount Security
that shall be deemed to be Outstanding for such purpose shall be the amount of the principal thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the Maturity thereof pursuant to
Section 5.2.

at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity, and no interest shall accrue on the amount so payable for the period from and after such Interest Payment

If any of the terms of a series of Debt Securities is established in or pursuant to a Board Resolution, a copy of such Board Resolution
shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series.

 Section 3.2.
Denominations. 
 In the absence of any specification pursuant to Section 3.1 with respect to the Debt Securities of
any series, the Debt Securities of such series shall be issuable only as Debt Securities in denominations of $2,000 and any integral multiple of $1,000 in excess thereof and shall be payable only in Dollars. 

Section 3.3. Execution, Authentication, Delivery and Dating. 
 The Debt Securities of any series shall be executed on behalf of the Company by its Chairman of the Board, a Vice Chairman, its Chief Executive Officer, its Chief Financial Officer, its Chief Operating
Officer, its President, one of its Vice Presidents or its Treasurer. The signature of any of these officers may be manual or facsimile. 
 Debt 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 Debt Securities or did not hold such offices at the date of such Debt Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Debt 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 Debt Securities and the Trustee in accordance with the Company Order shall authenticate and deliver such Debt Securities. If all the Debt Securities of any one series are not
to be issued at one time and if a Board Resolution or the Officers’ Certificate or other document pursuant to a Board Resolution or supplemental indenture relating to such series shall so permit, such Company Order may set forth procedures
acceptable to the Trustee for the issuance of such Debt Securities and for the determination of the terms thereof, such as interest rate, Stated Maturity, date of issuance and date from which interest, if any, shall accrue. 

The Trustee shall be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying upon, prior to the
authentication and delivery of the Debt Securities of such series, (i) the supplemental indenture or the Board Resolution by or pursuant to which the form and terms of such Debt Securities have been approved and (ii) an Opinion of Counsel
substantially to the effect that: 
 (1) the Company Order furnished by the Company to the Trustee in connection
with the authentication and delivery of such Debt Securities conforms to the requirements of this Indenture and constitutes sufficient authority hereunder for the Trustee to authenticate and deliver such Debt Securities; 

(2) the forms and terms (or, if applicable, the manner of determining the terms) of such Debt Securities are consistent
with the provisions of this Indenture; 
 (3) in the event that the forms or terms of such Debt Securities have
been established in a supplemental indenture, the execution and delivery of such supplemental indenture has been duly authorized by all necessary corporate action of the 

  
 20 









 
Company, such supplemental indenture has been duly executed and delivered by the Company and, assuming due authorization, execution and delivery by the Trustee, is a valid and binding obligation
enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity (regardless of
whether enforcement is sought in a proceeding in equity or at law) and subject to such other exceptions as counsel shall conclude do not materially affect the rights of the Holders of such Debt Securities; and 

(4) the execution and delivery of such Debt Securities have been duly authorized by all necessary corporate action of the
Company and such Debt Securities (if to be issued at the time of delivery of such Company Order) have been duly executed and delivered by the Company and, assuming due authentication by the Trustee and execution and delivery by the Company (if to be
issued after delivery of such Company Order in accordance with the foregoing procedures), are valid and binding obligations enforceable against the Company in accordance with their terms, entitled to the benefit of the Indenture, subject to
applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and
subject to such other exceptions as counsel shall conclude do not materially affect the rights of the Holders of such Debt Securities; and 
 (5) the amount of Debt Securities Outstanding of such series, together with the amount of such Debt Securities, does not exceed any limit established under the terms of this Indenture on the amount of
Debt Securities of such series that may be authenticated and delivered. 
 The Trustee shall not be required to authenticate
such Debt Securities if the issuance of such Debt Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Debt Securities and this Indenture in a manner which is not reasonably acceptable to
the Trustee. 
 Each Debt Security shall be dated the date of its authentication. 

Notwithstanding the provisions of Section 3.1 and of the preceding paragraphs, if all Debt Securities of a series are not to be
originally issued at one time, it shall not be necessary to deliver the Board Resolution or any Officers’ Certificate or other document pursuant to a Board Resolution otherwise required pursuant to Section 3.1 or the Company Order, the
Officers’ Certificate and Opinion of Counsel otherwise required pursuant to such preceding paragraphs or Sections 1.2 and 2.1 at or prior to the authentication of each Debt Security of such series if such documents are delivered at or prior to
the authentication upon original issuance of the first Debt Security of such series to be issued. 

  
 21 









  
 With respect to Debt
Securities of a series that are not to be originally issued at one time, the Trustee may rely, as to the authorization by the Company of any of such Debt Securities, the forms and terms thereof and the legality, validity, binding effect and
enforceability thereof, upon the Opinion of Counsel and the other documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as applicable, in connection with the first authentication of Debt Securities of such series. 

No Debt Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on
such Debt Security a certificate of authentication substantially in one of the forms provided for herein duly executed by an authorized officer of the Trustee or by an Authenticating Agent, and such certificate upon any Debt Security shall be
conclusive evidence, and the only evidence, that such Debt Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Debt Security shall have been duly
authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Debt Security to the Trustee for cancellation as provided in Section 3.8 together with a written statement (which need not comply
with Section 1.2) stating that such Debt Security has never been issued and sold by the Company, for all purposes of this Indenture such Debt Security shall be deemed never to have been authenticated and delivered hereunder and shall never be
entitled to the benefits of this Indenture. 
 Section 3.4. Temporary Debt Securities; Global Notes Representing Debt Securities.

 (a) Pending the preparation of definitive Debt Securities of any series, the Company may execute, and upon Company Order
the Trustee shall authenticate and deliver, temporary Debt Securities which are printed, lithographed, typewritten or otherwise produced, in any authorized denomination for Debt Securities of such series, substantially of the tenor of the definitive
Debt Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Debt Securities may determine, as conclusively evidenced by their execution of such
Debt Securities. Every such temporary Debt Security shall be executed by the Company and shall be authenticated and delivered by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the definitive
Debt Securities in lieu of which they are issued. 
 Except in the case of temporary Debt Securities in global form (which shall
be exchanged in accordance with the provisions of the following paragraphs), if temporary Debt Securities of any series are issued, the Company will cause definitive Debt Securities of such series to be prepared without unreasonable delay. After the
preparation of definitive Debt Securities of such series, the temporary Debt Securities of such series shall be exchangeable for definitive Debt Securities of such series, of a like Stated Maturity and with like terms and provisions, upon surrender
of the temporary Debt Securities of such series at the office or agency of the Company in a Place of Payment for such series, without charge to the Holder, except as provided in Section 3.5 in connection with a transfer. Upon surrender for
cancellation of any one or more temporary Debt Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Debt Securities of the same series of
authorized denominations and of a like Stated Maturity and like terms and provisions. Until so exchanged, the temporary Debt Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Debt
Securities of such series. 

  
 22 









  
 (b) If the Company
shall establish pursuant to Section 3.1 that the Debt Securities of a series are to be issued in whole or in part in the form of one or more Global Notes, then the Company shall execute and the Trustee shall, in accordance with Section 3.3
and the Company Order with respect to such series, authenticate and deliver one or more Global Notes that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the Outstanding Debt Securities of
such series to be represented by one or more Global Notes, (ii) shall be registered in the name of the Depositary for such Global Note or Notes or the nominee of such depositary, and (iii) shall bear a legend substantially to the following
effect: “This Debt Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary, unless and until this Debt Security is exchanged in whole or in part for Debt Securities in definitive form.” 

Notwithstanding any other provision of this Section or Section 3.5, unless and until it is exchanged in whole or in part for Debt
Securities in definitive form, a Global Note representing all or a portion of the Debt Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such depositary or by a nominee of such
depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor Depositary for such series or a nominee of such successor depositary. 

If at any time the Depositary for the Debt Securities of a series notifies the Company that it is unwilling or unable to continue as
Depositary for the Debt Securities of such series or if at any time the Depositary for Debt Securities of a series shall no longer be a clearing agency registered and in good standing under the Securities Exchange Act of 1934, as amended, or other
applicable statute or regulation, the Company shall appoint a successor Depositary with respect to the Debt Securities of such series. If a successor Depositary for the Debt Securities of such series is not appointed by the Company within 90 days
after the Company receives such notice or becomes aware of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series, will authenticate
and deliver, Debt Securities of such series in definitive form in an aggregate principal amount equal to the principal amount of the Global Note or Notes representing such series in exchange for such Global Note or Notes. 

The Company may at any time and in its sole discretion, subject to the procedures of the Depositary, determine that the Debt Securities
of any series issued in the form of one or more Global Notes shall no longer be represented by such Global Note or Notes. In such event, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery
of definitive Debt Securities of such series, will authenticate and deliver, Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Note or Notes representing such series in
exchange for such Global Note or Notes. 
 If the Debt Securities of any series shall have been issued in the form of one or
more Global Notes and if an Event of Default with respect to the Debt Securities of such series shall have occurred and be continuing, the Company will promptly execute, and the Trustee, upon receipt of a Company Order for the authentication and
delivery of definitive Debt Securities of such series, will authenticate and deliver, Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Note or Notes representing such
series in exchange for such Global Note or Notes. 

  
 23 









  
 If specified by the
Company pursuant to Section 3.1 with respect to Debt Securities of a series, the Depositary for such series of Debt Securities may surrender a Global Note for such series of Debt Securities in exchange in whole or in part for Debt Securities of
such series in definitive form on such terms as are acceptable to the Company and such depositary. Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without charge: 

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

(ii) to the Depositary a new Global Note in a denomination equal to the difference, if any, between the principal amount
of the surrendered Global Note and the aggregate principal amount of Debt Securities delivered to Holders thereof. 
 Upon the
exchange of a Global Note for Debt Securities in definitive form, such Global Note shall be canceled by the Trustee. Debt Securities issued in exchange for a Global Note pursuant to this subsection (c) shall be registered in such names and in
such authorized denominations as the Depositary for such Global Note, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall, at the expense of the Company, deliver such Debt
Securities to the Persons in whose names such Debt Securities are so registered. 
 No holder of any beneficial interest in any
Global Note held on its behalf by a Depositary (or its nominee) shall have any rights under this Indenture with respect to such Global Note or any Debt Security represented thereby, and such Depositary may be treated by the Company, the Trustee, and
any agent of the Company or the Trustee as the owner of such Global Note or any Debt Security represented thereby for all purposes whatsoever. None of the Company, the Trustee nor any agent of the Company or the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.
Notwithstanding the foregoing, with respect to any Global Note, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization
furnished by a Depositary or impair, as between a Depositary and such holders of beneficial interest, the operation of customary practices governing the exercise of the rights of the Depositary (or its nominees) as Holder of any Debt Security.


  
 24 









  
 Section 3.5.
Registration, Transfer and Exchange. 
 (a) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office or in any other office or agency of the Company in a Place of Payment being herein sometimes referred to as the “Security Register”) in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Debt Securities and of transfers and exchanges of Debt Securities. Such Security Register shall be in written form in the English language or in any other form capable of being
accurately and completely converted into such form within a reasonable time. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Debt Securities and registering transfers and exchanges of Debt Securities as
herein provided; provided, however, that the Company may appoint co-Security Registrars unless the terms of any series of Debt Securities provide otherwise. 
 Upon surrender for registration of transfer of any Debt Security of any series at the office or agency of the Company maintained for such purpose, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee, one or more new Debt Securities of the same series of like aggregate principal amount of such denominations as are authorized for Debt Securities of such series and of a like Stated
Maturity and with like terms and conditions. 
 Except as otherwise provided in Section 3.4 and this Section 3.5, at
the option of the Holder, Debt Securities of any series may be exchanged for other Debt Securities of the same series of like aggregate principal amount and of a like Stated Maturity and with like terms and conditions, upon surrender of the Debt
Securities to be exchanged at such office or agency. Whenever any Debt Securities are surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Debt Securities which the Holder making the exchange is
entitled to receive. 
 (b) All Debt Securities issued upon any transfer or exchange of Debt Securities shall be valid
obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Debt Securities surrendered for such transfer or exchange. 
 Every Debt Security presented or surrendered for transfer or 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 will be made for any transfer or exchange of Debt Securities except as provided in Section 3.6. 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, transfer or exchange of Debt Securities, other than those expressly provided in this Indenture to be made at the Company’s own expense or without expense or without
charge to the Holders. 
 The Company shall not be required (i) to register, transfer or exchange Debt Securities of any
series during a period beginning at the opening of business 15 days before the day of the transmission of a notice of redemption of Debt Securities of such series selected for redemption under Section 13.3 and ending at the close of business on
the day of such transmission, or (ii) to register, transfer or exchange any Debt Security so selected for redemption in whole or in part, except the unredeemed portion of any Debt Security being redeemed in part. 

  
 25 









  
 If at any time the
Depositary for any permanent global Debt Securities of any series notifies the Company that it is unwilling or unable to continue as Depositary for such permanent global Debt Securities or if at any time the Depositary for such permanent global Debt
Securities shall no longer be eligible to so continue under applicable law, the Company shall appoint a successor Depositary eligible under applicable law with respect to such permanent global Debt Securities. If a successor Depositary eligible
under applicable law for such global Debt Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility or if there has occurred and is continuing an Event of Default with
respect to the Debt Securities of any series, the Company will execute, and the Trustee, upon receipt of the Company Order for the authentication and delivery of definitive registered Debt Securities of such series and tenor, will authenticate and
deliver such definitive registered Debt Securities of such series and tenor, in any authorized denominations, in an aggregate principal amount equal to the principal amount of such permanent global Debt Securities, in exchange for such permanent
global Debt Securities. 
 The Company may at any time and in its sole discretion determine that any permanent global Debt
Securities of any series shall no longer be maintained in global form. In such event the Company will execute, and the Trustee, upon receipt of the Company Order for the authentication and delivery of definitive registered Debt Securities of such
series and tenor in any authorized denominations, in an aggregate principal amount equal to the principal amount of such permanent global Debt Securities, in exchange for such permanent global Debt Securities. 

Section 3.6. Mutilated, Destroyed, Lost and Stolen Debt Securities. 

If (i) any mutilated Debt Security is surrendered to the Trustee at its Corporate Trust Office, or (ii) the Company and the
Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security, and there is delivered to the Company and the Trustee such security or indemnity as may be satisfactory by them to save each of them and any
Paying Agent harmless, and neither the Company nor the Trustee receives notice that such Debt Security has been acquired by a bona fide purchaser, then the Company shall execute and upon Company Request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Debt Security, a new Debt Security of the same series of like Stated Maturity and with like terms and conditions and like principal amount, bearing a number not
contemporaneously Outstanding, 
 In case any such mutilated, destroyed, lost or stolen Debt Security has become or is about to
become due and payable, the Company in its discretion may, instead of issuing a new Debt Security, pay the amount due on such Debt Security in accordance with its terms. 
 Upon the issuance of any new Debt 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 respect thereto
and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

  
 26 









  
 Every new Debt
Security of any series issued pursuant to this Section shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debt 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 Debt 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 Debt
Securities. 
 Section 3.7. Payment of Interest; Interest Rights Preserved. 

(a) Unless otherwise specified as contemplated by Section 3.1 with respect to the Debt Securities of any series, interest on any Debt
Security which is payable and is punctually paid or duly provided for on any Interest Payment Date shall be paid to the Person in whose name such Debt Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest notwithstanding the cancellation of such Debt Security upon any transfer or exchange subsequent to the Regular Record Date. Unless otherwise specified as contemplated by Section 3.1 with respect to the Debt
Securities of any series, payment of interest on Debt Securities shall be made at the place or places specified pursuant to Section 3.1 or, at the option of the Company, by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or, if provided pursuant to Section 3.1, by wire transfer to an account designated by the Holder by the Regular Record Date. 
 (b) Any interest on any Debt Security 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 his 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 such Debt
Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee
in writing of the amount of Defaulted Interest proposed to be paid on each such Debt Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which date 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 

  
 27 









 
promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to the Holders of such Debt Securities at their addresses as they appear in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names such Debt Securities (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 Debt Securities in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Debt Securities may
be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

(c) Subject to the foregoing provisions of this Section, each Debt Security delivered under this Indenture upon transfer of or in
exchange for or in lieu of any other Debt Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debt Security. 
 Section 3.8. Cancellation. 
 Unless otherwise specified pursuant
to Section 3.1 for Debt Securities of any series, all Debt Securities surrendered for payment, redemption, transfer, exchange or credit against any sinking fund shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee. All Debt Securities so delivered shall be promptly canceled by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Debt 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 Debt Securities previously authenticated hereunder which the Company has not issued, and all Debt Securities
so delivered shall be promptly canceled by the Trustee. No Debt Securities shall be authenticated in lieu of or in exchange for any Debt Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled
Debt Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures. The acquisition of any Debt Securities by the Company shall not operate as a redemption or satisfaction of the indebtedness
represented thereby unless and until such Debt Securities are surrendered to the Trustee for cancellation. 
 Section 3.9.
Computation of Interest. 
 Except as otherwise specified pursuant to Section 3.1 for Debt Securities of any series,
interest on the Debt Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 

  
 28 









  
 Section 3.10. Currency
of Payments in Respect of Debt Securities. 
 Unless otherwise specified pursuant to Section 3.1 for Debt Securities of
any series, payment of the principal of (and premium, if any) and any interest on any Debt Security of such series will be made in Dollars. 

Section 3.11. CUSIP Numbers. 
 The Company in issuing Debt 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 that no representation is made as to the correctness of such numbers either as printed on the Debt 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 Debt 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 IV. 

SATISFACTION AND DISCHARGE 
 Section 4.1. Satisfaction and Discharge of Indenture. 
 This
Indenture, with respect to the Debt Securities of any series (if all series issued under this Indenture are not to be affected), shall, upon Company Request, cease to be of further effect with respect to any series of Debt Securities specified in
such Company Request (except as to any surviving rights of registration of transfer or exchange of such Debt Securities herein expressly provided for and rights to receive payments of principal (and premium, if any) and interest on such Debt
Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to such series of Debt Securities, when: 

(1) either 
 (A) all Debt Securities of such series theretofore authenticated and delivered (other than (i) Debt Securities of such series which have been destroyed, lost or stolen and which have been replaced or
paid as provided in Section 3.6 and (ii) Debt Securities of such series for whose payment money has theretofore been deposited in trust with the Trustee or any Paying Agent or segregated and held in trust by the Company and thereafter
repaid to the Company or discharged from such trust, as provided in Section 12.4) have been delivered to the Trustee for cancellation; or 
 (B) all Debt Securities of such series not theretofore delivered to the Trustee for cancellation, 
 (i) have become due and payable by reason of the giving of a notice of redemption or otherwise, or 

  
 29 









  
 (ii)
will become due and payable at their Stated Maturity within one year, or 
 (iii) are to be called for redemption
within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the Company either complies with any other condition or terms specified pursuant to Section 3.1, or if not so specified in the case of (i), (ii) or (iii) of this subclause (B), has
irrevocably deposited or caused to be deposited with the Trustee as trust funds held in trust solely for the benefit of the Holders, cash in United States Dollars in an amount, U.S. Government Obligations (as defined in Section 15.2) which
through the payment of interest and principal 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 a combination thereof, in such amounts as will be
sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on such Debt Securities not delivered to the Trustee for cancellation for principal, premium, if any and accrued interest to the date of
such deposit (in the case of Debt 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 
 (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture with respect to such series have been complied with. 
 Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Company to the Trustee under Section 6.7, and if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under
Section 4.2 and the last paragraph of Section 12.4, shall survive. 
 Section 4.2. Application of Trust Money, Etc.

 The Trustee and any Paying Agent shall promptly pay or return to the Company upon Company Request any moneys or U.S.
Government Obligations held by them at any time that are not required for the payment of the principal of (and premium, if any) and interest on the Debt Securities of any series for which money or U.S. Government Obligations have been deposited
pursuant to Section 4.1. 
 Subject to the provisions of the last paragraph of Section 12.4, all money deposited with
the Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in accordance with the provisions of the Debt Securities, if any, 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 premium, if any) and interest for whose payment such money has been deposited with the Trustee. 

  
 30 









  
 The Company shall pay
and shall indemnify the Trustee for any series of Debt Securities against any tax, fee or other charge imposed on or assessed against U.S. Government Obligations deposited pursuant to Section 4.1 or the interest and principal received in
respect of such U.S. Government Obligations other than any such tax, fee or other charge which by law is payable by or on behalf of Holders. The obligation of the Company under this Section 4.2 shall be deemed to be an obligation of the Company
under Section 6.7. 
 ARTICLE V. 
 REMEDIES 
 Section 5.1. Events of Default. 

“Event of Default” wherever used herein with respect to Debt Securities of any series, and unless otherwise provided with
respect to Debt Securities of any series pursuant to Section 3.1, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law, pursuant
to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 
 (1) default in the payment of any interest upon any Debt Security of such series when it becomes due and payable, and continuance of such default for a period of 30 days; or

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

  
 31 









  
 (5) the

 (6) the commencement by the Company of a voluntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State bankruptcy, insolvency or other similar

 Section 5.2. Acceleration of Maturity; Rescission and Annulment.

 If an Event of Default (unless otherwise provided with respect to Debt Securities of any series pursuant to
Section 3.1, other than an Event of Default specified in clauses (5) or (6) of Section 5.1) with respect to Debt Securities of any series at the time Outstanding occurs and is continuing, then in every such case, unless the
principal of all Debt Securities shall have already become due and payable, the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Debt Securities of such series may declare the principal amount (or, if any Debt
Securities of such series are Discount Securities or indexed securities, such portion of the principal amount of such Discount Securities as may be specified in the terms of such Discount Securities or indexed securities) of and all accrued but
unpaid interest on all the Debt Securities of such series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount)
plus accrued and unpaid interest (and premium, if payable) shall become immediately due and payable. Unless otherwise provided with respect to Debt Securities of any series pursuant to Section 3.1, if an Event of Default specified in clauses
(5) or (6) of Section 5.1 occurs, such amount shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Upon payment of such amount, all
obligations of the Company in respect of the payment of principal of (and premium, if payable) and interest on the Debt Securities of such series shall terminate. 

  
 32 









  
 At any time after such
a declaration of acceleration with respect to Debt 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 V provided, the Holders of a
majority in principal amount of the Outstanding Debt Securities of such 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 in the currency in which Debt Securities of
such series are payable 
 (A) all overdue installments of interest on all Debt Securities of such series,

 (B) the principal of (and premium, if any, on) any Debt Securities of such series which have become due
otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Debt Securities, 
 (C) to the extent that payment of such interest is lawful, interest upon overdue installments of interest on each Debt Security of such series at the rate or rates prescribed therefor in such Debt
Securities or, if no such rate or rates are so prescribed, at the rate borne by the Debt Securities during the period of such default, and 
 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; provided, however, that all sums
payable under this clause (D) shall be paid in Dollars; 
 and 

(2) All Events of Default with respect to Debt Securities of such series, other than the nonpayment of the principal of
Debt Securities of such series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. 
 No such rescission and waiver shall affect any subsequent default or impair any right consequent thereon. 
 Section 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee. 
 The Company covenants that if 
 (1) default is made in the payment
of any installment of interest on any Debt Security when such interest becomes due and payable and such default continues for a period of 30 days, 

  
 33 









  
 (2)
default is made in the payment of principal of (or premium, if any, on) any Debt Security at the Maturity thereof, or 
 (3) default is made in the making or satisfaction of any sinking fund payment or analogous obligation when the same becomes due pursuant to the terms of the Debt Securities of any series, and such default
continues for a period of 30 days, 
 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Debt
Securities, the amount then due and payable on such Debt Securities, for the principal (and premium, if any) and interest, if any, and, to the extent that payment of such interest shall be legally enforceable, interest upon the overdue principal
(and premium, if any) and upon overdue installments of interest, at the at the rate or rates prescribed therefor in such Debt Securities or, if no such rate or rates are so prescribed, at the rate borne by the Debt Securities; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

If the Company fails to pay such amount 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, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Debt 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 Debt Securities wherever situated. 
 If an Event of Default with respect to Debt 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
Debt Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy. 
 Section 5.4. Trustee May File Proofs of
Claim. 
 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement,
adjustment, composition or other judicial proceedings, or any voluntary or involuntary case under the Federal bankruptcy laws, as now or hereafter constituted, relative to the Company or any other obligor upon the Debt Securities, of a particular
series or all or substantially all of the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of such Debt Securities shall then be due and payable as therein expressed or by
declaration of acceleration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise, 

  
 34 









  
 (i) to
file and prove a claim for the whole amount of principal (or, if the Debt Securities of such series are Discount Securities, such portion of the principal amount as may be due and payable with respect to such series pursuant to a declaration in
accordance with Section 5.2) (and premium, if any) and interest owing and unpaid in respect of the Debt Securities of such series and to file such other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of such Debt Securities 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 receiver, assignee, trustee, custodian, liquidator, sequestrator (or other similar official) in any such proceeding is hereby authorized by each such 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 such Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.7. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Debt Securities of such series or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding. 
 Section 5.5. Trustee May Enforce Claims Without Possession of Debt Securities.

 All rights of action and claims under this Indenture or the Debt Securities of any series may be prosecuted and enforced
by the Trustee without the possession of any of such Debt 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 Debt Securities in
respect of which such judgment has been recovered. 
 Section 5.6. 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 (and premium, if any) or interest, upon presentation of the Debt Securities of any series in respect of which money has been collected 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 (including the reasonable compensation and the expenses and disbursements of its agents and counsel) amounts under Section 6.7; 

  
 35 









  
 SECOND:
To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Debt Securities of such series, 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 Debt Securities for principal (and premium, if any) and interest, respectively; and 
 THIRD: The balance, if any, to the Person or Persons entitled thereto. 

Section 5.7. Limitation on Suits. 
 No Holder of any Debt Security of any series shall have any right to institute any action or proceeding, judicial or otherwise, at law or in equity or in bankruptcy or otherwise, with respect to this
Indenture, or for the appointment of a receiver, trustee, liquidator, custodian, sequestrator (or similar official) or for any other remedy hereunder, unless 
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to such series, 

(2) the Holders of not less than 25% in principal amount of the Outstanding Debt Securities of such series shall have made
written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder, 
 (3) such Holder or Holders have offered to the Trustee indemnity and/or security 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 Debt Securities of such 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 such Holders or of
the Holders of Outstanding Debt Securities of any other series (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to 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. For the protection and
enforcement of the provisions of this Section 5.7, each and every Holder of Debt Securities of any series and the Trustee for such series shall be entitled to such relief as can be given at law or in equity. 

  
 36 









  
 Section 5.8.
Unconditional Right of Holders to Receive Principal, Premium and Interest. 
 Notwithstanding any other provision in this
Indenture, the Holder of any Debt Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 3.7) interest on such Debt Security on the respective
Stated Maturity or Maturities expressed in such Debt Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment and interest thereon, and such right shall not be impaired without
the consent of such Holder. 
 Section 5.9. Restoration of Rights and Remedies. 

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

Section 5.10. Rights and Remedies Cumulative. 
 Except as otherwise expressly provided elsewhere in this Indenture, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 5.11. Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder 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 any acquiescence therein. Every right and remedy given by this Indenture or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be. 
 Section 5.12. Control By Holders. 
 The Holders of a majority in principal amount of the Outstanding Debt Securities of any series shall have the right to direct in writing the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred by this Indenture on the Trustee with respect to the Debt Securities of such series, provided, that: 

(1) such direction shall not be in conflict with any rule of law or with this Indenture; 

  
 37 









  
 (2)
subject to the provisions of Section 6.1, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer or Responsible Officers of the Trustee, determine that the
proceeding so directed would be unjustly prejudicial to the Holders of Debt Securities of such series not joining in any such direction or would involve the Trustee in personal liability; and 

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

 Section 5.13. Waiver of Past Defaults. 
 The Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of any series may on behalf of the Holders of all the Debt Securities of any such series waive any
past default hereunder with respect to such series and its consequences, except a default: 
 (1) in the payment
of the principal of (or premium, if any) or interest on any Debt Security of such series, or in the payment of any sinking fund installment or analogous obligation with respect to the Debt Securities of such series; or 

(2) in respect of a covenant or provision hereof which pursuant to Article XI cannot be modified or amended without the
consent of the Holder of each Outstanding Debt Security of such series affected; provided that a majority in principal amount of the Outstanding Debt Securities of such series may rescind and annul a declaration of acceleration with respect to Debt
Securities of a given series, as provided in Section 5.2. 
 Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred, for every purpose of the Debt Securities of such series under this Indenture, but no such waiver shall extend to any subsequent or other default or
impair any right consequent thereon. 
 Section 5.14. Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any Debt Security by his acceptance thereof shall be deemed to have agreed, that
any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit other than the Trustee of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by such party litigant, but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit
instituted by any Holder or group of Holders holding in the aggregate 

  
 38 









 
more than 10% in principal amount of the Outstanding Debt Securities of any series, or to any suit instituted by any Holder of a Debt Security for the enforcement of the payment of the principal
of (or premium, if any) or interest on such Debt Security on or after the respective Stated Maturity or Maturities expressed in such Debt Security (or, in the case of redemption, on or after the Redemption Date).

 (a) Except during the continuance of an Event of Default with respect to the Debt Securities of any series: 
 (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against
the Trustee; and 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the
truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by
any provisions 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). 
 (b) In case an Event of Default with respect to
Debt Securities of any series has occurred and is continuing, the Trustee shall, with respect to the Debt Securities of such series, 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 such person’s own affairs. 
 (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

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

 (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer,
unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 

  
 39 









  
 (3) the
Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it with respect to Debt Securities of any series in good faith in accordance with the direction of the Holders of a majority in principal amount of the
Outstanding Debt Securities of such series 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; 

(4) the Trustee is under no obligation or duty to pay interest on or invest any funds deposited with it except as
specifically provided in this Indenture, and all investment activities undertaken by the Trustee, if any, shall be at and pursuant to the written instruction of the Company; and 

(5) the Trustee shall not be required 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 and/or security against such risk or liability is not
reasonably assured to it. 
 (d) 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 6.2. Notice of Defaults. 
 Within 90 days after the occurrence of any default hereunder with respect to Debt Securities of any series, the Trustee shall give notice to all Holders of Debt Securities of such series of such default
hereunder known to the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on any Debt Security of such series or
in the payment of any sinking fund installment with respect to Debt Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of Debt Securities of such series; and provided, further, that in the case of any default of the
character specified in Section 5.1(4) with respect to Debt Securities of such series no such notice to Holders shall be given until at least 90 days after the occurrence thereof. For the purpose of this Section, the term “default”
means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Debt Securities of such series. 
 Notice given pursuant to this Section 6.2 shall be transmitted by mail: 
 (1) to all Holders, as the names and addresses of the Holders appear in the Security Register; and

the proper party or parties;

omitted by it hereunder in good faith and in reliance thereon in accordance with such advice or Opinion of Counsel; 
 (e) the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders of Debt Securities of any series pursuant to this Indenture, unless such Holders shall have

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, Officers’
Certificate or other certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, unless requested in writing to do so by not less
than a majority of the Holders of the Outstanding Debt Securities affected thereby, 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; 
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any
misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 

  
 41 









  
 (h) the Trustee shall
not be charged with knowledge of any default or Event of Default hereunder unless (i) a Responsible Officer shall have actual knowledge thereof or (ii) the Trustee shall have received notice thereof in accordance with Section 1.4 from
the Company or any Holder and such notice is entitled “Notice of Default” and references this Indenture and the Debt Securities; and 
 (i) except as may be required in connection with any legal proceedings, the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

 Section 6.4. Not Responsible for Recitals or Issuance of Debt Securities. 

The recitals contained herein and in the Debt Securities, except the Trustee’s certificates of authentication, shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Debt Securities of any series. The Trustee shall not be
accountable for the use or application by the Company of any Debt Securities or the proceeds thereof. 
 Section 6.5. May Hold Debt
Securities. 
 The Trustee, any Paying Agent, the Security Registrar or any other agent of the Company, in its individual or
any other capacity, may become the owner or pledgee of Debt Securities, and, subject to Sections 6.8 and 6.13, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar or such
other agent. 
 Section 6.6. Money Held in Trust. 
 Money held by the Trustee or any Paying Agent in trust hereunder need not be segregated from other funds except to the extent required by law. Neither the Trustee nor any Paying Agent shall be under any
liability for (i) interest on any money received by it hereunder except as otherwise agreed in writing with the Company or (ii) losses resulting from currency fluctuations or any investments made pursuant to 6.1(c)(4). 

Section 6.7. Compensation and Reimbursement. 
 The Company agrees: 
 (1) to pay to the Trustee from time to time
such compensation as the Company and the Trustee shall from time to time agree in writing 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) to reimburse the Trustee in Dollars 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 to the extent any such
expense, disbursement or advance may be attributable to its negligence, bad faith or willful misconduct; and 

  
 42 









  
 (3) to
indemnify in Dollars the Trustee and its directors, officers, employees, representatives, agents and counsel for, and to hold them harmless against, any and all loss, claim, liability or expense incurred without negligence, bad faith, or willful
misconduct on its part, arising out of or in connection with the acceptance or administration of this trust or performance of the Trustee’s duties hereunder, including the reasonable costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of the Trustee’s powers or duties hereunder, except to the extent that any such claim or liability may be attributable to the its or their negligence, bad faith or willful

 As security for the performance of the obligations of the Company under this Section, the Trustee shall have a
claim senior to the Debt Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of amounts due on particular Debt Securities. 

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.1(5) or
Section 5.1(6), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency
or other similar law. 
 The obligations of the Company under this Section 6.7 to compensate and indemnify the Trustee and
its directors, officers, employees, representatives, agents and counsel and to reimburse it and them for expenses, disbursements and advances shall constitute additional indebtedness under this Indenture and shall survive the satisfaction and
discharge of this Indenture and the resignation or removal of the Trustee. 
 In the event that the Trustee is also acting as
Paying Agent, Registrar or in any other capacity hereunder, the rights, privileges, protections, immunities and benefits afforded to the Trustee pursuant to this Section 6.7, including, without limitation, its right to be indemnified, shall
also be afforded to the Trustee in its capacity as such Paying Agent, Registrar or in such other capacity and each agent, custodian and other person employed to act hereunder. 
 Section 6.8. Disqualification; Conflicting Interests. 
 If the Trustee
has or shall acquire any conflicting interest within the meaning of the TIA with respect to the Debt Securities of any series, then, within 90 days after ascertaining that it has such conflicting interest, and if the default to which such
conflicting interest relates has not been cured or duly waived or otherwise eliminated before the end of such 90-day period, the Trustee shall either eliminate such conflicting interest or resign with respect to the Debt Securities of such series,
to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture, and the Company shall take prompt steps to have a successor appointed, in the manner and with the effect hereinafter specified in this
Article. Nothing herein shall prevent the Trustee from filing with the Commission the application referred to in the penultimate paragraph of Section 310(b) of the TIA. 

  
 43 









  
 Section 6.9. Corporate Trustee
Required; Eligibility. 
 There shall at all times be a Trustee hereunder which shall 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 exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, subject to
supervision or examination by Federal, State or District of Columbia authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. Neither the Company nor any Person
directly or indirectly controlling, controlled by, or under common control with the Company shall serve as Trustee upon any Debt Securities. 

Section 6.10. Resignation and Removal; Appointment of Successor. 
 (a) 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 under
Section 6.11. 
 (b) The Trustee may resign at any time with respect to the Debt Securities of one or more series by giving
written notice thereof to the Company. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 60 days after the giving of such notice of resignation, the resigning Trustee may petition, at the
expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Debt Securities of such series. 
 (c) The Trustee may be removed at any time with respect to the Debt Securities of any series and a successor Trustee appointed by Act of the Holders of a majority in principal amount of the Outstanding
Debt Securities of such series, delivered to the Trustee and to the Company. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 60 days after the giving of such notice of removal, the Trustee
being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Debt Securities of such series. 

(d) If at any time: 
 (1) the Trustee shall fail to comply with Section 6.8 with respect to the Debt Securities of any series after written request therefor by the Company or by any Holder who has been a bona fide Holder
of a Debt Security of such series for at least six months, or 
 (2) the Trustee shall cease to be eligible under
Section 6.9 with respect to the Debt Securities of any series and shall fail to resign after written request therefor by the Company or by any such Holder, or 

  
 44 









  
 (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, (i) the Company by a Board Resolution may remove
the Trustee with respect to all Debt Securities, or (ii) subject to Section 5.14, any Holder who has been a bona fide Holder of a Debt Security of any series for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for the Debt Securities of such series. 
 (e) 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 Debt Securities of one or more series,
the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Debt Securities of that or those series (except as provided in Section 6.10(c)) (it being understood that any such successor Trustee
may be appointed with respect to the Debt 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 Debt Securities of any particular series) and shall comply with the applicable
requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Debt Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Debt 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, become the successor
Trustee with respect to the Debt Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Debt Securities of any series shall have been so appointed by the
Company or the Holders of such series and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Debt Security of such series for at least six months may, subject to Section 5.14, 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 Debt Securities of such series. 

(f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Debt Securities of any series
and each appointment of a successor Trustee with respect to the Debt Securities of any series in the manner and to the extent provided in Section 1.5 to the Holders of Debt Securities of such series. Each notice shall include the name of the
successor Trustee with respect to the Debt Securities of such series and the address of its Corporate Trust Office. 
 Section 6.11.
Acceptance of Appointment by Successor. 
 (a) In the case of an appointment hereunder of a successor Trustee with respect
to all Debt Securities, each 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 request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver 

  
 45 









 
an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in Section 6.7. 

(b) In case of the appointment hereunder of a successor Trustee with respect to the Debt Securities of one or more (but not all) series,
the Company, the retiring Trustee and each successor Trustee with respect to the Debt 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 Debt Securities of
that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Debt 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 Debt 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 any 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 other trust or trusts hereunder administered by any other such
Trustee; and upon the execution and delivery of any 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 Debt Securities of that or those series to which the appointment of such successor Trustee relates, but, on request of the
Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Debt Securities of that or those series to
which the appointment of such successor Trustee relates. 
 (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. 

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
 Section 6.12. 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 of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that
such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act 

  
 46 









 
on the part of any of the parties hereto. In case any Debt 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 Debt Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Debt Securities. In case any Debt Securities
shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Debt Securities, in either its own name or that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee. 
 Section 6.13. Preferential Collection of Claims Against
Company. 
 The Trustee shall comply with Section 311(a) of the Trust Indenture Act. A Trustee who has resigned or been
removed is subject to Section 311(a) of the Trust Indenture Act to the extent indicated therein. 
 Section 6.14. Appointment of
Authenticating Agent. 
 As long as any Debt Securities of a series remain Outstanding, upon a Company Request, there shall
be an authenticating agent (the “Authenticating Agent”) appointed, for such period as the Company shall elect, by the Trustee for such series of Debt Securities to act as its agent on its behalf and subject to its direction in connection
with the authentication and delivery of each series of Debt Securities for which it is serving as Trustee. Debt Securities of each such series authenticated by such Authenticating Agent shall be entitled to the benefits of this Indenture and shall
be valid and obligatory for all purposes as if authenticated by such Trustee. Wherever reference is made in this Indenture to the authentication and delivery of Debt Securities of any series by the Trustee for such series or to the Trustee’s
Certificate of Authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee for such series by an Authenticating Agent for such series and a Certificate of Authentication executed on behalf of such
Trustee by such Authenticating Agent, except that only the Trustee may authenticate Debt Securities upon original issuance and pursuant to Section 3.6 hereof. Such Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States of America or of any State, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $10,000,000 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 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 any 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 any
Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency business of any Authenticating Agent, shall continue to be the Authenticating Agent with respect to all series of Debt Securities
for which it served as Authenticating Agent without the execution or filing of any paper or any further act on the part of the Trustee for such series or such Authenticating Agent. 

  
 47 









  
 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 in the manner set forth in Section 1.4. Any Authenticating Agent may at any time, and if it shall cease to be
eligible shall, resign by giving written notice of resignation to the applicable Trustee and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.14 with respect to one or more or all series of Debt Securities, the Trustee for such series shall upon Company Request appoint a successor Authenticating Agent, and the Company shall
provide notice of such appointment to all Holders of Debt Securities of such series in the manner and to the extent provided in Section 1.5. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested
with all rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent herein. The Company agrees to pay to the Authenticating Agent for each series from time to time
reasonable compensation for its services. The Authenticating Agent for the Debt Securities of any series shall have no responsibility or liability for any action taken by it as such at the direction of the Trustee for such series. 

If an appointment with respect to one or more series is made pursuant to this Section, the Debt 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 Debt Securities of the series designated therein and referred to in the within-mentioned Indenture.

mailing of any material pursuant to a request made under Section 7.2(b).

the Company will:

which the Company may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended; provided, however, that the Company shall not be required to deliver to the Trustee

Trustee and the Commission, in accordance with rules and regulations prescribed from time to time by the Commission, such of the supplementary and periodic information, documents and reports which may be required pursuant to Section 13 of the

 ARTICLE VIII. 
 CONCERNING THE HOLDERS 

Section 8.1. Acts of Holders. 
 Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given 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 an agent or proxy 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. Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Outstanding Debt Securities of any series may take any Act, the fact that the Holders
of such specified percentage have joined therein may be evidenced (a) by the instrument or instruments executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of Holders voting in favor thereof at any
meeting of such Holders duly called and held in accordance with the provisions of Article IX, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. 

The Company may, at its option, by Company Order, fix in advance a record date for the determination of Holders of registered Debt
Securities entitled to give any request, demand, authorization, direction, notice, consent, waiver or other Act solicited by the Company, but the Company shall have no obligation to do so; provided, however, that the Company may not fix a
record date for the giving or making of any notice, declaration, request or direction referred to in the next sentence. In addition, the Trustee may, at its option, fix in advance a record date for the determination of Holders of registered Debt
Securities entitled to join in the giving or making of any Notice of Default, any declaration of acceleration referred to in Section 5.2, any request to institute proceedings referred to in Section 5.7 or any direction referred to in
Section 5.12. If any such record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act, or such notice, declaration, request or direction, may be given before or after such record date, but only the
Holders of registered Debt Securities of record at the close of business on the record date shall be deemed to be Holders of registered Debt Securities for the purposes of determining (i) whether Holders of the requisite proportion of the
Outstanding Debt Securities have authorized or agreed or consented to such Act (and for that purpose the Outstanding registered Debt Securities shall be computed as of the record date) and/or (ii) which Holders of registered Debt Securities may
revoke any such Act (notwithstanding Section 8.4); and any such Act, given as aforesaid, shall be effective whether or not the Holders of registered Debt Securities which authorized or agreed or consented to such Act remain Holders of
registered Debt Securities after such record date and whether or not the Debt Securities held by such Holders remain Outstanding after such record date. 

  
 51 









  
 Section 8.2. Proof of
Ownership; Proof of Execution of Instruments by Holder. 
 The ownership of Debt Securities of any series shall be proved by
the Security Register for such series or by a certificate of the Security Registrar for such series. 
 Subject to the
provisions of Sections 6.1, 6.3 and 9.5, proof of the execution of a writing appointing an agent or proxy and of the execution of any instrument by a Holder or his agent or proxy shall be sufficient and conclusive in favor of the Trustee and the
Company if made in a manner satisfactory to the Trustee. 
 The record of any Holders’ meeting shall be proved in the
manner provided in Section 9.6. 
 The Trustee may in any instance require further or other proof with respect to any of
the matters referred to in this Section so long as the request is a reasonable one. 
 Section 8.3. Persons Deemed Owners.

 The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Debt Security
is registered as the owner of such Debt Security for the purpose of receiving payment of the principal of (and premium, if any) and (subject to Section 3.7) interest, if any, on such Debt Security and for all other purposes whatsoever, whether
or not such Debt 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. All payments made to any Holder, or upon his order, shall be valid, and, to the
extent of the sum or sums paid, effectual to satisfy and discharge the liability for moneys payable upon such Debt Security. 

Section 8.4. Revocation of Consents; Future Holders Bound. 
 At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.1, of the taking of any Act by the Holders of the percentage in aggregate principal amount of the
Outstanding Debt Securities specified in this Indenture in connection with such Act, any Holder of a Debt Security the number, letter or other distinguishing symbol of which is shown by the evidence to be included in such Debt Securities, the
Holders of which have consented to such Act, by filing written notice with the Trustee at the Corporate Trust Office and reference this Indenture and the Debt Securities and upon proof of ownership as provided in Section 8.2, may revoke such
Act so far as it concerns such Debt Security. Except as aforesaid, any such Act taken by the Holder of any Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of such Debt Security and of any Debt Securities
issued on transfer or in lieu thereof or in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon such Debt Security or such other Debt Securities.

Trustee for such series to call a meeting of Holders of such series by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have given the notice of such meeting within 10 days

lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor corporation had been named as the Company herein, and thereafter the
predecessor Person (except in the case of a lease) shall be relieved of all obligations and covenants under this Indenture and the Debt Securities. 
 ARTICLE XI. 
 SUPPLEMENTAL INDENTURES 

Section 11.1. Supplemental Indentures Without Consent of Holders. 

Without the consent of any Holders, the Company, when authorized by a Board Resolution, and the Trustee for the Debt Securities of any
series, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes: 

(1) to evidence the succession of another Corporation to the rights of the Company and the assumption by such successor of
the covenants, agreements and obligations of the Company contained herein and in the Debt Securities; or

for the benefit of such series), or to surrender any right or power herein conferred upon the Company; or 
 (3)
to add any additional Events of Default (and if such Events of Default are to be applicable to less than all series, stating that such Events of Default are expressly being included solely to be applicable to such series); or 

(4) to change or eliminate any of the provisions of this Indenture, provided that any such change or elimination shall
become effective only when there is no Outstanding Debt Security of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision and as to which such supplemental indenture would apply;
or 
 (5) to secure the Debt Securities or to provide that any of the Company’s obligations under any series
of the Debt Securities shall be guaranteed and the terms and conditions for the release or substitution of such security or guarantee; or

supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Debt Securities pursuant to Article IV or XV, provided that any such action shall not
adversely affect the interests of the Holders of Debt Securities of such series or any other series of Debt Securities; or 
 (7) to establish the form or terms of Debt Securities of any series as permitted by Sections 2.1 and 3.1, including providing for conversion or other rights as contemplated by Section 3.1; or

 (8) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to
one or more series of Debt Securities and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, pursuant to the
requirements of Sections 6.10 and 6.11; or 
 (9) to cure any ambiguity, or to correct or supplement any
provision herein, or in any supplemental indenture, which may be defective or inconsistent with any other provision herein, to eliminate any conflict between the terms hereof and the Trust Indenture Act or to make any other provisions with respect
to matters or questions arising under this Indenture which shall not be inconsistent with any provision of this Indenture; provided any such action shall not adversely affect the interests of the Holders of Outstanding Debt Securities of any series
created prior to the execution of such supplemental indenture; or 
 (10) to change conversion rights in
accordance with Section 16.4. 
 Section 11.2. Supplemental Indentures With Consent of Holders. 

With the written consent of the Holders of not less than a majority in principal amount of all Outstanding Debt Securities 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 under this Indenture of such Debt Securities; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Debt Security affected thereby, 
 (1)
except as specifically provided with respect to any series of Debt Securities pursuant to Section 3.1, (a) change the Stated Maturity of the principal of, or installment of interest, if any, on, any Debt Security, or (b) reduce the
principal amount thereof or the interest thereon or any premium payable upon redemption thereof (provided that a requirement to offer to repurchase Debt Securities shall not be deemed a redemption for this purpose), or (c) change the currency
in which the principal of (and premium, if any) or interest on such Debt Security is denominated or payable, or (d) reduce the amount of the principal of a Discount Security that would be due and payable upon a declaration of acceleration of
the Maturity thereof pursuant to 

  
 57 









 
Section 5.2, or (e) reduce the amount of, or postpone the date fixed for, any payment under any sinking fund or analogous provisions for any Debt Security, or (f) impair the right
to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or (g) adversely affect the right to convert any Debt Security into shares of Common
Stock of the Company as may be provided pursuant to Section 3.1; 
 (2) reduce the percentage in principal
amount of the Outstanding Debt Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of this Indenture or

 (3) modify any of the
provisions of this Section, Section 5.13 or Section 12.7, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each
Outstanding Debt Security of each series affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in
this Section and Section 12.7, or the deletion of this proviso, in accordance with the requirements of Sections 6.10, 6.11 and 11.1(10). 
 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. 
 A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture
with respect to one or more particular series of Debt Securities, or which modifies the rights of the Holders of Debt 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 Debt securities of any other series. 
 Section 11.3. 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 receive, and (subject to Section 6.1) shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel each stating that the
execution of such supplemental indenture is authorized or permitted by this Indenture and otherwise complying with Section 1.2 hereof. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which adversely affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise in any material respect. 

  
 58

 ARTICLE XII.

 COVENANTS 

Section 12.1. Payment of Principal, Premium and Interest. 
 The Company covenants and agrees for the benefit of each series of Debt Securities that it will duly and punctually pay the principal of (and premium, if any) and interest on the Debt Securities in
accordance with the terms of the Debt Securities and this Indenture. 
 Section 12.2. Officer’s Certificate as to Default.

 Unless otherwise specifically provided for with respect to any series of Debt Securities under Section 3.1, the
Company will deliver to the Trustee, on or before a date not more than four months after the end of each fiscal year of the Company (which on the date hereof ends on December 31 of each year) ending after the date hereof, a certificate of the
principal executive officer, principal financial officer or principal accounting officer of the Company stating whether or not to the best knowledge of the signer thereof the Company is in compliance with all covenants and conditions under this
Indenture, and, if the Company shall be in default, specifying all such defaults and the nature thereof of which such signer may have knowledge. For purposes of this Section, such compliance shall be determined without regard to any period of grace
or requirement of notice provided under this Indenture. 

  
 59 









  
 Section 12.3.
Maintenance of Office or Agency. 
 The Company will maintain in each Place of Payment for each series of Debt Securities an
office or agency where Debt Securities of that series may be presented or surrendered for payment, where Debt Securities of that series may be surrendered for registration of transfer or exchange, where Debt Securities of that series that are
convertible may be surrendered for conversion, if applicable, and where notices and demands to or upon the Company in respect of the Debt Securities of that series and this Indenture may be served. The Trustee is hereby appointed Paying Agent and
the Corporate Trust Office of the Trustee is initially designated as the office or agency for the forgoing 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. 
 The Company may also from time to time designate different or additional offices or agencies to be maintained for
such purposes (in or outside of such Place of Payment), and may from time to time rescind any such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations described in the
preceding paragraph. The Company will give prompt written notice to the Trustee of any such additional designation or rescission of designation and any change in the location of any such different or additional office or agency. 

Section 12.4. Money for Debt 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 Debt Securities it will, on or before each due
date of the principal of (and premium, if any) or interest on any of the Debt Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action or failure so to act. 

Whenever the Company shall have one or more Paying Agents with respect to any series of Debt Securities, it will, by 10:00 a.m. (New York
City time) on each due date of the principal (and premium, if any) or interest on any Debt Securities of such series, deposit with any such Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such
sum to be held in trust for the benefit of the Persons entitled thereto, and (unless any such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 

Notwithstanding any term herein to the contrary, in no instance shall the Trustee be under any duty or obligation (i) to maintain
any office or to act in any capacity as an agent for any purpose under this Indenture (or any supplement hereto) outside the United States, or (ii) to act as a Paying Agent in respect of any currency other than Dollars. 

  
 60 









  
 The Company will cause
each Paying Agent with respect to any series of Debt 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) hold all sums held by it for the payment of the principal of (and premium, if any) or
interest on Debt Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Debt Securities of such series)
in the making of any payment of principal (and premium, if any) or interest on the Debt Securities of such series; and 
 (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay,
or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Debt Security of any series and
remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company upon Company Request, or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Debt 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 transmitted, in the manner and to the extent
provided by Section 1.5, 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 notification, any unclaimed balance of such money then remaining will be
repaid to the Company. 
 Section 12.5. Restriction on Liens. 

Unless otherwise specified pursuant to Section 3.1, the Company agrees that it will not, nor will it permit any Restricted Subsidiary
to, create, incur, issue, assume or guarantee any Secured Debt without in any such case effectively providing, concurrently with the creation, incurrence, issuance, assumption or guarantee of any such Secured Debt, that the Debt Securities (together
with, if 

  
 61 









 
the Company shall so determine, any other indebtedness of or guaranteed by the Company or such Restricted Subsidiary ranking equally with the Debt Securities and then existing or thereafter
created) shall be secured equally and ratably with or prior to such Secured Debt so long as such Secured Debt shall be secured. The term “Secured Debt” means notes, bonds, debentures or other similar evidences of indebtedness for money
borrowed secured by any Lien. The foregoing restrictions shall not apply to: 
 (1) Liens on property, shares of stock or
Indebtedness of any entity existing at the time such entity becomes a Restricted Subsidiary; 
 (2) Liens on property or shares
of stock existing at the time of acquisition of such property or stock by the Company or a Restricted Subsidiary or existing as of the date of this Indenture; 
 (3) Liens to secure the payment of all or any part of the price of acquisition, construction or improvement of such property or stock by the Company or a Restricted Subsidiary, or to secure any Secured
Debt incurred by the Company or a Restricted Subsidiary, prior to, at the time of, or within 360 days after the later of the acquisition or completion of construction (including any improvements on an existing property), which Secured Debt is
incurred for the purpose of financing all or any part of the purchase price thereof or construction of improvements thereon; provided, however, that, in the case of any such acquisition, construction or improvement, the Lien shall not apply to any
property theretofore owned by the Company or a Restricted Subsidiary, other than, in the case of any such construction or improvement, any theretofore substantially unimproved real property on which the property or improvement so constructed is
located; 
 (4) Liens securing Secured Debt of a Restricted Subsidiary owing to the Company or to another Restricted Subsidiary;

 (5) Liens on property of an entity existing at the time such entity is merged into or consolidated with the Company or a
Restricted Subsidiary or at the time of a sale, lease or other disposition of the properties of an entity as an entirety or substantially as an entirety to the Company or a Restricted Subsidiary; 

(6) Liens on property of the Company or a Restricted Subsidiary in favor of the United States of America or any state thereof, or any
department, agency or instrumentality or political subdivision of the United States of America or any state thereof, or in favor of any other country or any political subdivision thereof, or any department, agency or instrumentality of such country
or political subdivision, to secure partial progress, advance or other payments pursuant to any contract or statute or to secure any indebtedness incurred for the purpose of financing all or any part of the purchase price or the cost of construction
of the property subject to such Liens; 
 (7) Liens upon any Principal Property, or any transfer or disposition of any Principal
Property, that is created or implemented as a necessary component of a bond for title transaction, payment in lieu of tax agreement or other tax incentive vehicle designed to provide the Company or any Subsidiary with certain ad valorem property tax
or other incentive savings; or 

  
 62 









  
 (8) Liens incurred or
assumed in connection with the issuance of revenue bonds the interest on which is exempt from federal taxation pursuant to Section 103 of the Code and the regulations thereunder; 

(9) Liens to secure Hedging Obligations entered into in the ordinary course of business to purchase any raw material or other commodity
or to hedge risks or reduce costs with respect to the interest rate, currency or commodity exposure of the Company or any Restricted Subsidiary of the Company and not for speculative purposes. 

(10) any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part of any Lien referred
to in the foregoing clauses (1) through (9); provided, however, that the principal amount of Secured Debt secured thereby shall not exceed the principal amount of Secured Debt so secured at the time of such extension, renewal or replacement
(except any amounts committed at the date of the indenture),, and that such extension, renewal or replacement shall be limited to all or a part of the property which secured the Lien so extended, renewed or replaced (plus improvements and
construction on such property). 
 Notwithstanding the foregoing provisions of this Section 12.5, the Company and any one
or more Restricted Subsidiaries may, without securing the Securities, create, incur, issue, assume or guarantee Secured Debt secured by a Lien which would otherwise be subject to the foregoing restrictions in an aggregate amount which, together with
all other Secured Debt of the Company and its Restricted Subsidiaries which (if originally created, incurred, issued, assumed or guaranteed at such time) would otherwise be subject to the foregoing restrictions (not including Secured Debt permitted
to be secured under clauses (1) through (10) above), does not at the time exceed 15% of Consolidated Net Tangible Assets of the Company as shown on the financial statements of the Company as of the end of the fiscal year preceding the date
of determination. 
 Section 12.6. Restrictions on Sale and Leaseback Transactions. 

Unless otherwise specified pursuant to Section 3.1, the Company agrees that it will not, nor will it permit any Restricted Subsidiary
to, enter into any Sale and Leaseback Transaction unless: 
 (1) the Company or such Restricted Subsidiary would be entitled,
pursuant to the provisions of Section 12.5, to create, incur, issue, assume or guarantee indebtedness secured by a Lien upon such property at least equal in amount to the Attributable Debt in respect of such arrangement without equally and
ratably securing the Debt Securities; provided, however, that from and after the date on which such arrangement becomes effective, the Attributable Debt in respect of such arrangement shall be deemed for all purposes under Section 12.5 to be
Secured Debt subject to the provisions of Section 12.5; or 
 (2) since the date of this Indenture and within a period
commencing twelve months prior to the consummation of such Sale and Leaseback Transaction and ending twelve months after the consummation of such Sale and Leaseback Transaction, the Company or any Restricted Subsidiary, as the case may be, has
expended, or will expend, for the Principal Property an amount equal to (A) the net proceeds of such Sale and Leaseback Transaction, and the Company elects to designate such amount as a credit against such Sale and


  
 63 









 
Leaseback Transaction, or (B) a part of the net proceeds of such Sale and Leaseback Transaction and the Company elects to designate such amount as a credit against such Sale and Leaseback
Transaction and applies an amount equal to the remainder of the net proceeds as provided in clause (3) hereof; or 
 (3)
such Sale and Leaseback Transaction does not come within the exceptions provided by clause (1) hereof and the Company does not make the election permitted by clause (2) hereof or makes such election only as a part of such net proceeds, in
either of which events the Company shall apply an amount in cash equal to the Attributable Debt in respect of such arrangement (less any amount elected under clause (2) hereof) to the retirement, within 360 days of the effective date of any
such arrangement, of indebtedness for borrowed money of the Company or any Restricted Subsidiary (other than indebtedness for borrowed money of the Company which is subordinated to the Debt Securities) which by its terms matures at or is extendible
or renewable at the sole option of the obligor without requiring the consent of the obligees to a date more than twelve months after the date of the creation of such indebtedness for borrowed money (it being understood that such retirement may be
made by prepayment of such indebtedness for borrowed money, if permitted by the terms thereof, as well as by payment at maturity and that at the option of the Company and pursuant to the terms of this Indenture, such indebtedness may include the
Debt Securities). 
 The term “Sale and Leaseback Transaction” means any arrangement with any Person providing for the
leasing by the Company or any Restricted Subsidiary of any Principal Property, whether such Principal Property is now owned or hereafter acquired (except for temporary leases for a term, including renewals at the option of the lessee, of not more
than three years and except for leases between the Company and a Restricted Subsidiary or between Restricted Subsidiaries), which property has been or is to be sold or transferred by the Company or such Restricted Subsidiary to such Person with the
intention of taking back a lease of such property. 
 The term “Attributable Debt” means the present value (discounted
at the weighted average interest rate borne by the Debt Securities Outstanding at the time of such Sale and Leaseback transaction compounded semiannually) of the obligation of a lessee for net rental payments during the remaining term of any lease
(including any period for which such lease has been extended). 
 Section 12.7. Waiver of Certain Covenants. 

The Company may omit in any particular instance to comply with any term, provision or condition set forth in any covenant not set forth
herein and specified pursuant to Section 3.1 to be applicable to the Debt Securities of any series and to be subject to this Section 12.7), with respect to the Debt Securities of such series, except as otherwise provided pursuant to
Section 3.1, with respect to the Debt Securities of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Debt 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 expressly so 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.

 ARTICLE XIII.

 REDEMPTION OF DEBT SECURITIES 
 Section 13.1. Applicability of Article. 
 Debt Securities of any
series which are redeemable before their Maturity shall be redeemable in accordance with their terms and (except as otherwise specified pursuant to Section 3.1 for Debt Securities of any series) in accordance with this Article. 

Section 13.2. Election to Redeem; Notice to Trustee. 
 The election of the Company to redeem any Debt Securities shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company, the Company shall, not less than 30 nor more
than 60 days before the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Debt Securities of such series to be redeemed. In
the case of any redemption of Debt Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Debt Securities or elsewhere in this Indenture, or (b) pursuant to an election of the Company
which is subject to a condition specified in the terms of such Debt Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restrictions or condition.

 Section 13.3. Selection by Trustee of Debt Securities to be Redeemed. 

Except in the case of a redemption in whole of the Debt Securities of such series, if less than all the Debt Securities of any series are
to be redeemed at the election of the Company, the particular Debt Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Debt Securities of such series not previously
called for redemption on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Debt
Securities of such series or any integral multiple thereof) of the principal amount of Debt Securities of such series in a denomination larger than the minimum authorized denomination for Debt Securities of such series pursuant to Section 3.2.
The portions of the principal amount of Debt Securities so selected for partial redemption shall be equal to the minimum authorized denominations for Debt Securities of such series pursuant to Section 3.2 or any integral multiple thereof,
except as otherwise set forth in the applicable form of Debt Securities. In any case when more than one Debt Security of such series is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered
as if it were represented by one Debt Security of such series. 
 The Trustee shall promptly notify the Company in writing of
the Debt Securities selected for redemption and, in the case of any Debt Securities selected for partial redemption, the principal amount thereof to be redeemed. 

  
 65 









  
 If any Debt Security
selected for partial redemption is converted in part before the Redemption Date, the converted portion of such Debt Security shall be deemed, to the fullest extent practicable, to be the portion selected for redemption. Debt Securities which have
been converted during a selection of Debt Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Debt Securities shall relate, in the case of any Debt Security redeemed or to be
redeemed only in part, to the portion of the principal amount of such Debt Security which has been or is to be redeemed. 
 Section 13.4.
Notice of Redemption. 
 Notice of redemption shall be given by the Company, or at the Company’s written request to
the Trustee not less than 45 days prior to the Redemption Date (unless the Trustee permits a period of less than 45 days), by the Trustee in the name and at the expense of the Company, not less than 30 days and not more than 60 days prior to the
Redemption Date to the Holders of Debt Securities of any series to be redeemed in whole or in part pursuant to this Article XIII, in the manner provided in Section 1.5. Any notice so given shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice. Failure to give such notice, or any defect in such notice to the Holder of any Debt Security of a series designated for redemption, in whole or in part, shall not affect the sufficiency of any notice
of redemption with respect to the Holder of any other Debt Security of such series. 
 All notices of redemption shall state:

 (1) the Redemption Date; 

(2) the Redemption Price or, if not then ascertainable, the manner of calculation thereof; 

(3) that Debt Securities of such series are being redeemed by the Company pursuant to provisions contained in this
Indenture or the terms of the Debt Securities of such series or a supplemental indenture establishing such series, if such be the case, together with a brief statement of the facts permitting such redemption; 

(4) if less than all Outstanding Debt Securities of any series are to be redeemed, the identification (and, in the case of
partial redemption, the principal amounts) of the particular Debt Securities to be redeemed; 
 (5) that on the
Redemption Date the Redemption Price will become due and payable upon each such Debt Security to be redeemed, and that interest thereon, if any, shall cease to accrue on and after said date; 

(6) the Place or Places of Payment where such Debt Securities are to be surrendered for payment of the Redemption Price;


  
 66 









  
 (7) the
CUSIP number, if any, and that no representation is made as to the accuracy or correctness of the CUSIP number, if any, listed on such notice or printed on the Debt Securities; and 

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

Section 13.5. Deposit of Redemption Price. 
 On or prior to 10:00 a.m. (New York City time) on the Redemption Date for any Debt Securities, 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 12.4) an amount of money sufficient to pay the Redemption Price of such Debt Securities or any portions thereof which are to be redeemed on that date. 

Section 13.6. Debt Securities Payable on Redemption Date. 
 Notice of redemption having been given as aforesaid, any Debt Securities so to be redeemed shall become due and payable on the Redemption Date at the Redemption Price, and from and after such date (unless
the Company shall default in the payment of the Redemption Price) such Debt Securities shall cease to bear interest. Upon surrender of any such Debt Security for redemption in accordance with said notice, such Debt Security shall be paid by the
Company at the Redemption Price; provided that, unless otherwise specified as contemplated by Section 3.1, installments of interest on Debt Securities which have a Stated Maturity on or prior to the Redemption Date for such Debt Securities
shall be payable according to the terms of such Debt Securities and the provisions of Section 3.7. 
 If any Debt Security
called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Debt Security. 

Section 13.7. Debt Securities Redeemed in Part. 
 Any Debt Security which is to be redeemed only in part shall be surrendered at the Corporate Trust Office or such other office or agency of the Company as is specified pursuant to Section 3.1 with,
if the Company, the Security Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company, the Security Registrar 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 Debt Security without service charge, a new Debt Security or Debt Securities of the same series, of like tenor
and form, 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 Debt Security so surrendered. In the case of a Debt Security providing
appropriate space for such notation, at the option of the Holder thereof, the Trustee, in lieu of delivering a new Debt Security or Debt Securities as aforesaid, may make a notation on such Debt Security of the payment of the redeemed portion
thereof.

Section 14.1. Applicability of Articles. 
 The provisions of this Article XIV shall be applicable to any sinking fund for the retirement of Debt Securities of a series except as otherwise specified pursuant to Section 3.1 for Debt Securities
of such series. 
 The minimum amount of any sinking fund payment provided for by the terms of Debt Securities of any series is
herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Debt Securities of any series is herein referred to as an “optional sinking fund payment.” If
provided for by the terms of Debt Securities of any series, the amount of any cash sinking fund payment may be subject to reduction as provided in Section 14.2. Each sinking fund payment shall be applied to the redemption of Debt Securities of
any series as provided for by the terms of Debt Securities of such series. 
 Section 14.2. Satisfaction of Mandatory Sinking Fund
Payments with Debt Securities. 
 In lieu of making all or any part of a mandatory sinking fund payment with respect to any
Debt Securities of a series in cash, the Company may at its option, at any time no more than sixteen months and no less than 45 days prior to the date on which such sinking fund payment is due, deliver to the Trustee Debt Securities of such series
theretofore purchased or otherwise acquired by the Company, except Debt Securities of such series which have been redeemed through the application of mandatory sinking fund payments pursuant to the terms of the Debt Securities of such series,
accompanied by a Company Order instructing the Trustee to credit such obligations and stating that the Debt Securities of such series were originally issued by the Company by way of bona fide sale or other negotiation for value, provided that such
Debt Securities shall not have been previously so credited. Such Debt Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Debt Securities for redemption through operation of the sinking
fund and the amount of such mandatory sinking fund payment shall be reduced accordingly. 
 Section 14.3. Redemption of Debt Securities
for Sinking Fund. 
 Not less than 45 days prior to each sinking fund payment date for any series of Debt Securities (unless
a shorter period shall be satisfactory to the Trustee), the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the
portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Debt Securities of such series pursuant to Section 14.2 and shall state the basis for
such credit and that such Debt Securities have not previously been so credited and whether the Company intends to exercise its rights to make a permitted optional sinking fund payment with respect to such series. Such certificate shall be
irrevocable and upon its delivery the Company shall be obligated to make the cash payment or payments 

  
 68 









 
therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Company to deliver such certificate, the sinking fund payment due on the
next 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 Debt Securities of such series subject to a mandatory sinking fund payment without the right to
deliver or credit Debt Securities as provided in Section 14.2 and without the right to make any optional sinking fund payment with respect to such series at such time. 
 If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund payments
made in cash shall exceed $50,000 (or a lesser sum if the Company shall so request with respect to the Debt Securities of any series), such cash shall be applied on the next succeeding sinking fund payment date to the redemption of Debt Securities
of such series at the sinking fund redemption price thereof together with accrued interest thereon to the date fixed for redemption. If such amount shall be $50,000 (or such lesser sum) or less and the Company makes no such request then it shall be
carried over until a sum in excess of $50,000 (or such lesser sum) is available. 
 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 Debt Securities of any particular series shall, subject to the preceding paragraph, be applied by the Trustee (to the extent
it is acting as a Paying Agent with respect to Dollars) or other Paying Agent appointed by the Company (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 Debt Securities of such series at the Redemption Price specified in such Debt Securities with
respect to the sinking fund. Any sinking fund moneys not so applied or allocated by the Trustee (to the extent it is acting as a Paying Agent with respect to Dollars) or other Paying Agent appointed by the Company (or by the Company if the Company
is acting as its own Paying Agent) to the redemption of Debt Securities shall be added to the next sinking fund payment received by the Trustee (to the extent it is acting as a Paying Agent with respect to Dollars) or other Paying Agent appointed by
the Company (or if the Company is acting as its own Paying Agent, segregated and held in trust as provided in Section 12.4) for such series and, together with such payment (or such amount so segregated) shall be applied in accordance with the
provisions of this Section. Any and all sinking fund moneys with respect to the Debt Securities of any particular series held by the Trustee (to the extent it is acting as a Paying Agent with respect to Dollars) or other Paying Agent appointed by
the Company (or if the Company is acting as its own Paying Agent, segregated and held in trust as provided in Section 12.4) on the last sinking fund payment date with respect to Debt Securities of such series and not held for the payment or
redemption of particular Debt Securities of such series shall be applied by the Trustee (to the extent it is acting as a Paying Agent with respect to Dollars) or other Paying Agent appointed by the Company (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 Debt Securities of such series at Maturity. 

  
 69 









  
 The Trustee shall
select or cause to be selected the Debt Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 13.3 and the Company shall cause notice of the redemption thereof to be given in the manner provided in
Section 13.4. Such notice having been duly given, the redemption of such Debt Securities shall be made upon the terms and in the manner stated in Section 13.6. 
 On or before 10:00 a.m. (New York City time) on each sinking fund payment date, the Company shall pay to the Trustee (to the extent it is acting as a Paying Agent with respect to Dollars) or other Paying
Agent appointed by the Company (or, if the Company is acting as its own Paying Agent, the Company shall segregate and hold in trust as provided in Section 12.4) in cash a sum equal to the principal and any interest accrued to the Redemption
Date for Debt Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section. 

Neither the Trustee, any Paying Agent nor the Company shall redeem any Debt Securities of a series with sinking fund moneys or give any
notice of redemption of Debt 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 Debt Securities of such series or of any Event of Default (other than
an Event of Default occurring as a consequence of this paragraph) with respect to the Debt Securities of such series, except that if the notice of redemption shall have been provided in accordance with the provisions hereof, the Trustee or
applicable Paying Agent (or the Company, if the Company is then acting as its own Paying Agent) shall redeem such Debt Securities if cash sufficient for that purpose shall be deposited with the Trustee or such other Paying Agent as provided above
(or segregated by the Company) for that purpose in accordance with the terms of this Article. 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 Debt Securities of such series; provided, however, that in case such default or Event of Default
shall have been cured or waived as provided herein, such moneys shall thereafter be applied on or prior to the next sinking fund payment date for the Debt Securities of such series on which such moneys may be applied pursuant to the provisions of
this Section. 
 ARTICLE XV. 
 DEFEASANCE 
 Section 15.1. Applicability of Article. 

Except as otherwise provided pursuant to Section 3.1, the provisions of this Article shall be applicable. 

Section 15.2. Defeasance Upon Deposit of Moneys or U.S. Government Obligations. 

At the Company’s option, either (a) the Company shall be deemed to have been Discharged (as defined below) from its obligations
with respect to Debt Securities of any series (“legal defeasance option”) or (b) the Company shall cease to be under any 

  
 70 









 
obligation to comply with any term, provision or condition set forth in clauses (ii) and (iv) of Section 10.1 with respect to Debt Securities of any series (and, if so specified
pursuant to Section 3.1, any other obligation of the Company or restrictive covenant added for the benefit of such series pursuant to Section 3.1), and any noncompliance with such terms, provisions or covenants shall not constitute a
default or Event of Default with respect to the Debt Securities of that series (“covenant defeasance option”), at any time after the applicable conditions set forth below have been satisfied: 

(1) the Company shall have deposited or caused to be deposited irrevocably with the Trustee as trust funds in trust,
specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Debt Securities of such series, (i) money in an amount, or (ii) U.S. Government Obligations (as defined below) which through the payment of
interest and principal 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 (iii) a combination of (i) and (ii), sufficient, in the opinion (with
respect to (i), (ii) and (iii)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal (including any mandatory
sinking fund payments) of and premium, if any, and interest on, the Outstanding Debt Securities of such series on the dates such installments of interest or principal and premium are due; 

(2) such deposit shall not cause the Trustee with respect to the Debt Securities of that series to have a conflicting
interest as defined in Section 6.8 and for purposes of the Trust Indenture Act with respect to the Debt Securities of any series; 
 (3) such deposit will not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound;

 (4) if the Debt Securities of such series are then listed on any national securities exchange, the Company
shall have delivered to the Trustee an Opinion of Counsel or a letter or other document from such exchange to the effect that the Company’s exercise of its option under this Section would not cause such Debt Securities to be delisted;

 (5) no Event of Default or event (including such deposit) which, with notice or lapse of time or both, would
become an Event of Default with respect to the Debt Securities of such series shall have occurred and be continuing on the date of such deposit and, with respect to the legal defeasance option only, no Event of Default under Section 5.1(5) or
Section 5.1(6) or event which with the giving of notice or lapse of time, or both, would become an Event of Default under Section 5.1(5) or Section 5.1(6) shall have occurred and be continuing on the 91st day after such date; and


  
 71 









  
 (6) if
the Debt Securities are to be redeemed prior to Stated Maturity (other than from mandatory sinking fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to this Indenture or provision therefor
satisfactory to the Trustee shall have been made; and 
 (7) the Company shall have delivered to the Trustee an
Opinion of Counsel or a ruling from the Internal Revenue Service to the effect that the Holders of the Debt Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit, defeasance or
Discharge. 
 Notwithstanding the foregoing, if the Company exercises its covenant defeasance option and an Event of Default under
Section 5.1(5) or Section 5.1(6) or event which with the giving of notice or lapse of time, or both, would become an Event of Default under Section 5.1(5) or Section 5.1(6) shall have occurred and be continuing on the 91st day
after the date of such deposit, the obligations of the Company referred to under the definition of covenant defeasance option above with respect to such Debt Securities shall be reinstated. 

Notwithstanding the Company’s exercise of the covenant defeasance option, the Company may subsequently exercise the legal defeasance
option. 
 “Discharged” means that the Company shall be deemed to have paid and discharged the entire indebtedness
represented by, and obligations under, the Debt Securities of such series and to have satisfied all the obligations under this Indenture relating to the Debt Securities of such series (and the Trustee for such series of Debt Securities, at the
expense of the Company, shall execute proper instruments acknowledging the same), except (A) the rights of Holders of Debt Securities of such series to receive, from the trust fund described in clause (1) above, payment of the principal of
(and premium, if any) and interest on such Debt Securities when such payments are due, (B) the Company’s obligations with respect to the Debt Securities of such series under Sections 3.4, 3.5, 3.6, 12.3 and 15.3 and (C) the rights,
powers, trusts, duties and immunities of the Trustee hereunder. 
 “U.S. Government Obligations” means securities that
are (i) direct obligations of the United States for the payment of which its full faith and credit is pledged, or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States the
payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States, which, in either case under clauses (i) or (ii), are not callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank or trust company as custodian with respect to any such U.S. Government Obligation or a specific payment of interest on or principal of any such U.S. Government Obligation held by such custodian for the
account of the holder of a depository receipt; 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 depository receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment of interest on or principal of the U.S. Government Obligation evidenced by such depository receipt. 

  
 72 









  
 Section 15.3. Deposited Moneys
and U.S. Government Obligations to be Held in Trust. 
 All moneys and U.S. Government Obligations deposited with the Trustee
pursuant to Section 15.2 in respect of Debt Securities of a series shall be held in trust and applied by it, in accordance with the provisions of such Debt 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 Holders of such Debt Securities, of all sums due and to become due thereon for principal (and premium, if any) and interest, if any, but such money
need not be segregated from other funds except to the extent required by law. 
 Section 15.4. Repayment to Company. 

The Trustee and any Paying Agent shall promptly pay or return to the Company upon Company Request any moneys or U.S. Government
Obligations held by them at any time that, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the same opinion provided pursuant to
Section 15.2(1)), are not required for the payment of the principal of (and premium, if any) and interest on the Debt Securities of any series for which money or U.S. Government Obligations have been deposited pursuant to Section 15.2.

 The provisions of the last paragraph of Section 12.4 shall apply to any money held by the Trustee or any Paying Agent
under this Article that remains unclaimed for two years after the Maturity of any series of Debt Securities for which money or U.S. Government Obligations have been deposited pursuant to Section 15.2. 

The Company shall pay and shall indemnify the Trustee for any series of Debt Securities against any tax, fee or other charge imposed on
or assessed against U.S. Government Obligations deposited pursuant to Section 15.2 or the interest and principal received in respect of such U.S. Government Obligations other than any such tax, fee or other charge which by law is payable by or
on behalf of Holders. The obligation of the Company under this Section 15.4 shall be deemed to be an obligation of the Company under Section 6.7.
