effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and
evidenced 

  
 -12- 








 
thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument
or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and the
Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 15.6. 

Without limiting the generality of this Section 1.4, unless otherwise provided in or pursuant to this Indenture, a Holder, including a
U.S. Depositary that is a Holder of a global Security, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this

standing instructions and customary practices. 
 The Company shall fix a record date for the purpose of determining the Persons who are
beneficial owners of interest in any permanent global Security held by a U.S. Depositary entitled under the procedures of such U.S. Depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other Act, whether or not such Holders remain Holders after such record date. No such request, demand,
authorization, direction, notice, consent, waiver or other Act shall be valid or effective if made, given or taken more than 90 days after such record date. 

(2) The fact and date of the execution by any Person of any such instrument or writing referred to in this Section 1.4 may
be proved in any reasonable manner; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this Section. 

(3) The ownership, principal amount and serial numbers of Registered Securities held by any Person, and the date of the
commencement and the date of the termination of holding the same, shall be proved by the Security Register. 
 (4) The
ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, may be proved by the production of such Bearer Securities or by a
certificate executed, as depositary, by any trust company, bank, banker or other depositary reasonably acceptable to the Company, wherever situated, if such certificate shall be deemed by the Company and the Trustee to be satisfactory, showing that
at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if
such certificate or affidavit is 

  
 -13- 








 
deemed by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (i) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (ii) such Bearer Security is produced to the Trustee by some other Person, or (iii) such Bearer Security is surrendered in exchange for a Registered Security, or
(iv) such Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by the Person so executing such instrument or writing and the date of the commencement and the date of the
termination of holding the same may also be proved in any other manner which the Company and the Trustee deem sufficient. 

(5) If the Company shall solicit from the Holders of any Registered Securities any request, demand, authorization, direction,
notice, consent, waiver or other Act, the Company may at its option (but is not obligated to), by Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders
of Registered Securities of record at the close of business on such record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by
the Holders of Registered Securities shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 

(6) Any request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall
bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done or suffered to be done by the Trustee, any
Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security. 
  

	 	Section 1.5.	Notices, etc. to Trustee and Company. 

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

in writing (or by confirmed facsimile transmission to (312) 726-2158) to or with the Trustee at its Corporate Trust Office, or 

(2) the Company by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly

	 	Section 1.6.	Notice to Holders of Securities; Waiver. 

 Except as otherwise expressly provided in or
pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event, 
 (1) such
notice shall be sufficiently given to Holders of Registered Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such event, at his address as it appears in the Security Register, not
later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice; and 
 (2) such
notice shall be sufficiently given to Holders of Bearer Securities, if any, if published in an Authorized Newspaper in The City of New York and, if such Securities are then listed on any stock exchange outside the United States, in an Authorized
Newspaper in such city as the Company shall advise the Trustee that such stock exchange so requires, on a Business Day at least twice, the first such publication to be not earlier than the earliest date and the second such publication to be not
later than the latest date prescribed for the giving of such notice. 
 In any case where notice to Holders of Registered Securities is
given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or
the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the
suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made by any reasonable alternate method of delivery, with notice of such to be provided to
the Trustee, shall constitute a sufficient notification for every purpose hereunder. 
 In case by reason of the suspension of publication
of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of Bearers Securities as provided above, then such notification to Holders of Bearer Securities as shall
be made by such reasonable alternate method of publication or notice, with notice of such to be provided to the Trustee, shall constitute sufficient notice to such Holders for every purpose hereunder. Neither failure to give notice by publication to
Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of any notice mailed to Holders of Registered Securities as provided above. 

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

	 	Section 1.7.	Language of Notices.

Legal Holiday at any Place of Payment, then (notwithstanding any other

provision of this Indenture, any Security or any Coupon other than a provision in any Security or Coupon that specifically states that such provision shall apply in lieu hereof) payment need not

Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with clause (a)), in any currency other than the Required
Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an
alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and
(iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of

provided by the Company in or pursuant to the Board Resolution and set forth in the Officers’ Certificate or in any indenture or indentures supplemental hereto pertaining to such series of Securities. The terms of the Securities of any series
may provide, without limitation, that the Securities shall be authenticated and delivered by the Trustee on original issue from time to time upon written order of persons designated in the Officers’ Certificate or supplemental indenture and

	 	Section 3.2.	Currency; Denominations. 

 Unless otherwise provided in or pursuant to this Indenture,
the principal of, any premium and interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars. Unless otherwise provided in or pursuant to this Indenture, Registered Securities denominated in Dollars shall be
issuable in registered form without Coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, and the Bearer Securities denominated in Dollars shall be issuable in the denomination of $5,000 and integral
multiples thereof. Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture. 

 

	 	Section 3.3.	Execution, Authentication, Delivery and Dating. 

 Securities shall be executed on behalf
of the Company by its Chairman of the Board, the Chief Executive Officer, a President, its Chief Financial Officer, its Treasurer or a Vice President under its corporate seal reproduced thereon and attested by its Secretary or one of its Assistant
Secretaries. Coupons shall be executed on behalf of the Company by the Treasurer or any Assistant Treasurer of the Company. The signature of any of these officers on the Securities or any Coupons appertaining thereto may be manual or facsimile. 

Securities and any Coupons appertaining thereto bearing the manual or facsimile signatures of individuals who were at any time the proper
officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities and Coupons or did not hold such offices at the date of
original issuance of such Securities or Coupons. 
 At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities, together with any Coupons appertaining thereto, executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental
indenture or indentures with respect to such Securities referred to in Section 3.1 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order
and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities and any
Coupons appertaining thereto, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon, 

(1) an Opinion of Counsel to the effect that: 

(a) the form or forms and terms of such Securities and Coupons, if any, have been established in conformity with the provisions
of this Indenture; 
 (b) all conditions precedent to the authentication and delivery of such Securities and Coupons, if any,
appertaining thereto, have been complied with and that such Securities and Coupons, when completed by appropriate insertions, executed under the Company’s corporate seal and attested by duly authorized officers of the Company, delivered by duly
authorized officers of the Company to 

  
 -24- 








 
the Trustee for authentication pursuant to this Indenture, and authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be subject to or limited by bankruptcy, insolvency,
reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws relating to or affecting creditors’ rights generally, and subject to general principles of equity (regardless of whether enforcement is
sought in a proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this Indenture; such Opinion of Counsel need express no opinion as to the availability of equitable remedies; 

(c) all laws and requirements in respect of the execution and delivery by the Company of such Securities and Coupons, if any,
have been complied with; and 
 (d) this Indenture has been qualified under the Trust Indenture Act; and 

(2) an Officers’ Certificate stating that all conditions precedent to the execution, authentication and delivery of such
Securities and Coupons, if any, appertaining thereto, have been complied with and that, to the best knowledge of the Persons executing such certificate, no event which is, or after notice or lapse of time would become, an Event of Default with
respect to any of the Securities shall have occurred and be continuing. 
 If all the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver an Opinion of Counsel and an Officers’ Certificate at the time of issuance of each Security, but such opinion and certificate, with appropriate modifications, shall be delivered at or before the time
of issuance of the first Security of such series. After any such first delivery, any separate written request by an Authorized Officer of the Company that the Trustee authenticate and deliver Securities of such series for original issue will be
deemed to be a certification by the Company that all conditions precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied with. 

The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised
by counsel, determines that such action may not lawfully be taken. 
 Each Registered Security shall be dated the date of its
authentication. Each Bearer Security and any Bearer Security in global form shall be dated as of the date specified in or pursuant to this Indenture. 

No Security or Coupon appertaining thereto shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose,
unless there appears on such Security a 

  
 -25- 








 
certificate of authentication substantially in the form provided for in Section 2.2 or 6.11 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of
one of its authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Except as permitted by Section 3.6 or 3.7, the
Trustee shall not authenticate and deliver any Bearer Security unless all Coupons appertaining thereto then matured have been detached and cancelled. 

The Company initially appoints the Depository Trust Company (“DTC”) to act as Depository with respect to the global
Securities. 
 The Company initially appoints the Trustee to act as the Securities Custodian for the global Securities. 

 

	 	Section 3.4.	Temporary Securities. 

 Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 3.3, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized in or pursuant to this Indenture, in bearer form with one or more
Coupons or without Coupons and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities.
Such temporary Securities may be in global form. 
 Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities of the same series and
containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such
Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing identical terms and provisions; provided, however, that no definitive Bearer Security, except as
provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary Registered Security; and provided, further, that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in
compliance with the conditions set forth in or pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, until so exchanged the temporary Securities of any series shall in all
respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 

  
 -26- 









	 	Section 3.5.	Registration, Transfer and Exchange. 

 With respect to the Registered Securities of each
series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series. Such Office or Agency shall be the “Security Registrar”
for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by
the Company and shall have accepted such appointment by the Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register
for such series at all reasonable times. There shall be only one Security Register for each series of Securities. 
 Upon surrender for
registration of transfer of any Registered Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or
more new Registered Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions. 

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series
containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. 

If provided in or pursuant to this Indenture, with respect to Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing identical terms, denominated as authorized in or pursuant to this Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured Coupon or Coupons or matured Coupon or
Coupons in default, such exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company and the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the surrender of
such missing Coupon or Coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to any Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive 

  
 -27- 








 
the amount of such payment; provided, however, that, except as otherwise provided in Section 10.2, interest represented by Coupons shall be payable only upon presentation and
surrender of those Coupons at an Office or Agency for such series located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at such Office or Agency on (i) any Regular Record Date and before the opening of business at such Office or Agency on the next succeeding Interest Payment Date, or
(ii) any Special Record Date and before the opening of business at such Office or Agency on the related date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date
or proposed date of payment, as the case may be (or, if such Coupon is so surrendered with such Bearer Security, such Coupon shall be returned to the Person so surrendering the Bearer Security), and interest or Defaulted Interest, as the case may
be, shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when
due in accordance with the provisions of this Indenture. 
 If provided in or pursuant to this Indenture with respect to Securities of any
series, at the option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to such series. 

Whenever any Securities are surrendered for exchange as contemplated by the immediately preceding two paragraphs, the Company shall execute,
and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 

Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depositary is at any time unwilling, unable or ineligible to continue as Depositary and a successor Depositary is not appointed by the Company within 90 days of the date the Company is so informed in
writing, (ii) the Company executes and delivers to the Trustee a Company Order to the effect that such global Security shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with respect to the Securities and
the Depositary requests the issuance of certificated notes. If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii) or
(iii) of the preceding sentence, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and
denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such global Security, executed by the Company. On or after the
earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the U.S. Depositary or such other Depositary as shall be specified in the Company Order with respect thereto, and in accordance
with instructions given to the Trustee and the U.S. Depositary or such other Depositary, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an Officers’ Certificate or be accompanied by an
Opinion of Counsel unless requested by the 

  
 -28- 








 
Trustee), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive
Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for such surrendered global Security or portion thereof, a like aggregate principal amount of definitive Securities of the same
series of authorized denominations and of like tenor as such global Security or portion thereof to be exchanged, which (unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the global Security or portion thereof shall be issuable only in the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof; as shall be specified by the beneficial owner thereof, but subject to the satisfaction of any certification or other requirements to the issuance of Bearer Securities; provided, however, that no such
exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date; and provided, further, that (unless otherwise
provided in or pursuant to this Indenture) no Bearer Security delivered in exchange for a portion of a global Security shall be mailed or otherwise delivered to any location in the United States. Promptly following any such exchange in part, such
global Security shall be returned by the Trustee to such Depositary or the U.S. Depositary, as the case may be, or such other Depositary or U.S. Depositary referred to above in accordance with the instructions of the Company referred to above. If a
Registered Security is issued in exchange for any portion of a global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before
the opening of business at such Office or Agency on the next succeeding Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for
payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but shall be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the provisions of this Indenture. 

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company evidencing the
same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange. 

Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the
Company or the Security Registrar for such Security) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such Security duly executed by the Holder thereof or his
attorney duly authorized in writing. 
 No service charge by the Company shall be made for any registration of transfer or exchange, or
redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in connection with any
registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer. 

  
 -29- 








 Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required
(i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Securities of like tenor and the same series under
Section 11.3 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Registered Security selected for redemption in whole or in part, except in the case of any Security to be
redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security selected for redemption except, to the extent provided with respect to such Bearer Security, that such Bearer Security may be exchanged for a
Registered Security of like tenor and the same series, provided that such Registered Security shall be immediately surrendered for redemption with written instruction for payment consistent with the provisions of this Indenture or (iv) to
issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid. 

 

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

 If any mutilated Security or a
Security with a mutilated Coupon appertaining to it is surrendered to the Trustee, subject to the provisions of this Section 3.6, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of
the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if any, appertaining to the surrendered Security. 

If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any
Security or Coupon, and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security or Coupon has been
acquired by a bona fide purchaser, the Company shall execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a new Security of the same series containing identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen Coupon appertains. 

Notwithstanding the foregoing provisions of this Section 3.6, in case any mutilated, destroyed, lost or stolen Security or Coupon has
become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security or Coupon; provided, however, that payment of principal of, any premium or interest on or any Additional
Amounts with respect to any Bearer Securities shall, except as otherwise provided in Section 10.2, be payable only at an Office or Agency for such Securities located outside the United States and, unless otherwise provided in or pursuant to
this Indenture, any interest on Bearer Securities and any Additional Amounts with respect to such interest shall be payable only upon presentation and surrender of the Coupons appertaining thereto. 

  
 -30- 








 Upon the issuance of any new Security under this Section 3.6, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Security, with any Coupons appertaining thereto issued pursuant to this Section 3.6 in lieu of any destroyed, lost or stolen
Security, or in exchange for a Security to which a destroyed, lost or stolen Coupon appertains shall constitute a separate obligation of the Company, whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series and any Coupons, if any, duly
issued hereunder. 
 The provisions of this Section 3.6, as amended or supplemented pursuant to this Indenture with respect to
particular Securities or generally, shall be exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons. 

 

	 	Section 3.7.	Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved. 


Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest. 
 Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall
forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or
(2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Person in whose name such
Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed by the Company in the following manner. The Company shall
notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Registered Security, the Special Record Date therefor 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 

  
 -31- 








 
on or prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Person entitled to such Defaulted Interest as in this Clause provided. The
Special Record Date for the payment of such Defaulted Interest 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 notification to the Trustee of the proposed payment.
The Trustee shall, in the name and at the expense of the Company, 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 Holder of such Registered
Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company cause a
similar notice to be published at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered Security (or a Predecessor
Security thereof) shall be 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 in any other lawful manner not inconsistent with the requirements of
any securities exchange on which such Security 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 payment shall be
deemed practicable by the Trustee. 
 Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series
pursuant to the provisions of this Indenture, at the option of the Company, interest on Registered Securities that bear interest may be paid by mailing a check to the address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a bank located in the United States. 
 Subject to the foregoing
provisions of this Section and Section 3.5, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue,
which were carried by such other Security. 
 In the case of any Registered Security of any series that is convertible into shares of Common
Stock or exchangeable for other securities, which Registered Security is converted or exchanged after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Registered Security with respect to which the
Stated Maturity is prior to such Interest Payment Date), interest with respect to which the Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion or exchange, and such
interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Registered Security (or one or more predecessor Registered Securities) is registered at the close of business on such Regular Record Date.
Except as otherwise expressly provided in the immediately preceding sentence, in the case of any 

  
 -32- 








 
Registered Security which is converted or exchanged, interest with respect to which the Stated Maturity is after the date of conversion or exchange of such Registered Security shall not be
payable. 
  

	 	Section 3.8.	Persons Deemed Owners. 

 Prior to due presentment of a Registered Security for
registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered in the Security Register as the owner of such Registered Security for the
purpose of receiving payment of principal of, any premium and (subject to Sections 3.5 and 3.7) interest on and any Additional Amounts with respect to such Registered Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 

The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security or the bearer of any Coupon
as the absolute owner of such Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not any payment with respect to such Security or Coupon shall be overdue, and none
of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 No Holder of any
beneficial interest in any global Security held on its behalf by a Depositary shall have any rights under this Indenture with respect to such global Security, 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 Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar 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 Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

 

	 	Section 3.9.	Cancellation. 

 All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and Coupons, as well as Securities and
Coupons surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which
the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this
Section, except as expressly permitted by or pursuant to this Indenture. All cancelled Securities and Coupons held by the Trustee shall be disposed of in accordance with its customary procedures. Copies of all cancelled Securities shall be provided
to the Company by the Trustee, promptly following cancellation of such Securities.

	 	Section 3.10.	Computation of Interest. 

 Except as otherwise provided in or pursuant to this Indenture
or in any Security, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, money in the Currency in
which such Securities are payable in an amount sufficient to pay the entire indebtedness on such Securities and any Coupons appertaining thereto not theretofore delivered to the Trustee for cancellation, including the principal of, any premium and

respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 4.1(1)(b)), and with respect to any rights to convert or exchange such Securities into Common Stock or other securities shall
survive. 
  

	 	Section 4.2.	Defeasance and Covenant Defeasance. 

 (1) Unless pursuant to
Section 3.1, either or both of (i) defeasance of the Securities of or within a series under clause (2) of this Section 4.2 shall not be applicable with respect to the Securities of such series or (ii) covenant defeasance of
the Securities of or within a series under clause (3) of this Section 4.2 shall not be applicable with respect to the Securities of such series, then such provisions, together with the other provisions of this Section 4.2 (with such
modifications thereto as may be specified pursuant to Section 3.1 with respect to any Securities), shall be applicable to such Securities and any Coupons appertaining thereto, and the Company may at its option by Board Resolution, at any time,
with respect to such Securities and any Coupons appertaining thereto, elect to have Section 4.2(2) or Section 4.2(3) be applied to such Outstanding Securities and any Coupons appertaining thereto upon compliance with the conditions set
forth below in this Section 4.2. 

  
 -35- 








 (2) Upon the Company’s exercise of the above option applicable to this
Section 4.2(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any Coupons appertaining thereto on the date the
conditions set forth in clause (4) of this Section 4.2 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness
represented by such Outstanding Securities and any Coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause (5) of this Section 4.2 and the other Sections of this
Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other obligations under such Securities and any Coupons appertaining thereto and this Indenture insofar as such Securities and any Coupons appertaining
thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of
Holders of such Outstanding Securities and any Coupons appertaining thereto to receive, solely from the trust fund described in clause (4) of this Section 4.2 and as more fully set forth in such clause, payments in respect of the principal
of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities and any Coupons appertaining thereto when such payments are due, and any rights of such Holder to convert such Securities into Common
Stock or exchange such Securities for other securities, (ii) the obligations of the Company and the Trustee with respect to such Securities under Sections 3.5, 3,6, 10.2 and 10.3 and with respect to the payment of Additional Amounts, if any, on
such Securities as contemplated by Section 10.4 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 4.2(4)(a)
below), and with respect to any rights to convert such Securities into Common Stock or exchange such Securities for other securities, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this
Section 4.2. The Company may exercise its option under this Section 4.2(2) notwithstanding the prior exercise of its option under clause (3) of this Section 4.2 with respect to such Securities and any Coupons appertaining
thereto. 
 (3) Upon the Company’s exercise of the option to have this Section 4.2(3) apply with respect to any
Securities of or within a series, the Company shall be released from its obligations under Section 8.1, Section 10.5 and Section 10.6, and, to the extent specified pursuant to Section 3.1(19), any other covenant applicable to
such Securities, with respect to such Outstanding Securities and any Coupons appertaining thereto on and after the date the conditions set forth in clause (4) of this Section 4.2 are satisfied (hereinafter, “covenant
defeasance”), and such Securities and any Coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of
any thereof) in connection with any such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities and any
Coupons 

  
 -36- 








 
appertaining thereto, the Company may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such Section or such other covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a default or an Event of Default under Section 5.1(4) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and Coupons appertaining
thereto shall be unaffected thereby. 
 (4) The following shall be the conditions to application of clause (2) or
(3) of this Section 4.2 to any Outstanding Securities of or within a series and any Coupons appertaining thereto: 

(a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the
requirements of Section 6.7 who shall agree to comply with the provisions of this Section 4.2 applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated
solely to, the benefit of the Holders of such Securities and any Coupons appertaining thereto, (1) an amount in Dollars or in such Foreign Currency in which such Securities and any Coupons appertaining thereto are then specified as payable, or

any) and interest, if any, on such Securities and any Coupons appertaining thereto, money in an amount, or (3) a combination thereof, in any case, in an amount, sufficient, without consideration of any reinvestment of such principal and
interest, in the opinion of a nationally recognized firm of Independent Public Accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, (y) the principal of (and premium, if any) and interest, if any, on such Outstanding Securities and any Coupons appertaining thereto at the Stated Maturity of such principal or installment of principal or premium
or interest (including any Redemption Date that the Company irrevocably specifies at the time of such defeasance or covenant defeasance) and (z) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities
and any Coupons appertaining thereto on the days on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any Coupons appertaining thereto. 

(b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this
Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound. 
 (c) No
Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities and any 

  
 -37- 








 
Coupons appertaining thereto shall have occurred and be continuing on the date of such deposit and, with respect to defeasance only, at any time during the period ending on the 91st day after the
date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 

(d) In the case of an election under clause (2) of this Section 4.2, the Company shall have delivered to the Trustee
an Opinion of Counsel stating that (i) the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service a Revenue Ruling, or (ii) since the date of execution of this
Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities and any Coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance
had not occurred. 
 (e) In the case of an election under clause (3) of this Section 4.2, the Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant
defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 

(f) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, after the 91st day after the date
of deposit, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds thereof) deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant to this
clause (4) to be held in trust will not be subject to any case or proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency, reorganization or other similar law, or any decree or
order for relief in respect of the Company issued in connection therewith. 
 (g) The Company shall have delivered to the
Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance under clause (2) or (3) of this Section 4.2 (as the case may be) have been complied
with. 
 (h) Notwithstanding any other provisions of this Section 4.2(4), such defeasance or covenant defeasance shall
be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 3.1. 

(5) Unless otherwise specified in or pursuant to this Indenture or any Security, if, after a deposit referred
to in Section 4.2(4)(a) has been made, (a) the Holder of a 

  
 -38- 








 Security in respect of which such deposit was made is entitled to, and does, elect pursuant to
Section 3.1 or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 4.2(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of
the Foreign Currency in which the deposit pursuant to Section 4.2(4)(a) has been made, the indebtedness represented by such Security and any Coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and satisfied
through the payment of the principal of (and premium, if any), and interest, if any, on, and Additional Amounts, if any, with respect to, such Security as the same becomes due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on (x) in the case of
payments made pursuant to clause (a) above, the applicable market exchange rate for such Currency in effect on the second Business Day prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange
rate for such Foreign Currency in effect (as nearly as feasible) at the time of the Conversion Event. 
 The Company shall pay and indemnify
the Trustee (or other qualifying trustee, collectively for purposes of this Section 4.2(5) and Section 4.3, the “Trustee”) against any tax, fee or other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 4.2 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto. 
 Anything in this Section 4.2 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company
from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4) of this Section 4.2 which, in the opinion of a nationally recognized firm of
Independent Public Accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in
accordance with this Section 4.2. 
 In the case where an election is made under clause (3) of this Section 4.2 with respect
to a Security and the Security is declared due and payable because of the occurrence of any Event of Default (other than an Event of Default with respect to any covenant as to which there has been covenant defeasance), if the amount in Dollars or
Foreign Currency in which the Security is payable, and Government Obligations on deposit with the Trustee, will be sufficient to pay amounts due on the Security at the time of the stated maturity or earlier redemption but is not sufficient to pay
amounts due on the Security at the time of the acceleration resulting from the Event of Default, the Company shall remain liable to make payment of the amounts due at the time of acceleration. 

 

	 	Section 4.3.	Application of Trust Money. 

 Subject to the provisions of the last paragraph of
Section 10.3, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1)

be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and any Coupons appertaining thereto 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 Securities and any Coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium, if any) and interest and Additional Amounts,
if any; but such money and Government Obligations need not be segregated from other funds except to the extent required by law.

in principal amount of the Outstanding 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 

  
 -40- 








 (5) if any event of default as defined in any mortgage, indenture or instrument
under which there may be issued, or by which there may be secured or evidenced, any Debt of the Company (including any Event of Default under any other series of Securities), whether such Debt now exists or shall hereafter be created or incurred,
shall happen and shall consist of default in the payment of more than $100 million in principal amount of such Debt at the maturity thereof (after giving effect to any applicable grace period) or shall result in such Debt in principal amount in
excess of $100 million becoming or being declared due and payable prior to the date on which it would otherwise become due and payable; provided, however, that if such default under such mortgage, indenture or instrument is cured by the
Company, or waived by the holders of such Debt, in each case as many be permitted by such mortgage, indenture or instrument, then the event of default under this Indenture caused by such default will be deemed likewise to be cured or waived; 

(6) the entry by a court having competent jurisdiction of: 

(a) a decree or order for relief in respect of the Company in an involuntary proceeding under any applicable bankruptcy,
insolvency, reorganization or other similar law and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days; or

	 	Section 5.2.	Acceleration of Maturity; Rescission and Annulment. 

 If an Event of Default with respect
to Securities of any series at the time Outstanding (other than an Event of Default specified in clause (6) or (7) of Section 5.1) occurs and is continuing either the Trustee or the Holders of not less than 25% in principal amount of
the Outstanding Securities of such series may declare the principal amount of all the Securities of such series, or such lesser amount as may be provided for in the 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 the Holders), and upon any such declaration such principal or such lesser amount shall become immediately due and payable. 

If an Event of Default specified in clause (6) or (7) of Section 5.1 occurs, all unpaid principal of and accrued
interest on the Outstanding Securities of that series (or such lesser amount as may be provided for in the Securities of such series) 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 of any Security of that series. 
 At any time after a declaration of acceleration with respect to the
Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a majority in principal amount of the
Outstanding 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 of money sufficient to pay 

(a) all overdue installments of any interest on and Additional Amounts with respect to all Securities of such series and any
Coupon appertaining thereto, 
 (b) the principal of and any premium on any Securities of such series which have become due
otherwise than by such declaration of acceleration and interest thereon and any Additional Amounts with respect thereto at the rate or rates borne by or provided for in such Securities, 

(c) to the extent that payment of such interest or Additional Amounts is lawful, interest upon overdue installments of any
interest and Additional Amounts at the rate or rates borne by or provided for in such Securities, 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 and all other amounts due the Trustee under Section 6.6; and 

(2) all Events of Default with respect to Securities of such series, other than the non-payment of the principal of, any
premium and interest on, and any Additional Amounts with respect to Securities of such series which shall have become due solely by such declaration of acceleration, shall have been cured or waived as provided in Section 5.13. 

  
 -42- 








 No such rescission shall affect any subsequent default or impair any right consequent thereon.

  

	 	Section 5.3.	Collection of Indebtedness and Suits for Enforcement by Trustee. 

 The Company covenants
that if 
 (1) default is made in the payment of any installment of interest on or any Additional Amounts with respect to any
Security or any Coupon appertaining thereto when such interest or Additional Amounts shall have become due and payable and such default continues for a period of 30 days, or 

(2) default is made in the payment of the principal of or any premium on any Security or any Additional Amounts with respect
thereto at their Maturity, 
 the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities and any
Coupons appertaining thereto, the whole amount of money then due and payable with respect to such Securities and any Coupons appertaining thereto, with interest upon the overdue principal, any premium and, to the extent that payment of such interest
shall be legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount of money as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee under Section 6.6. 

If the Company fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the
Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money 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 Securities and any Coupons appertaining thereto and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon
such Securities and any Coupons appertaining thereto, wherever situated. 
 If an Event of Default with respect to Securities of any series
occurs and is continuing with respect to Securities of any series at the time Outstanding, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series and any Coupons
appertaining thereto 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 such Securities or
in aid of the exercise of any power granted herein or therein, 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 similar judicial proceeding relative to the Company or any other obligor upon the Securities of any series or the property of the Company or such
other obligor or their creditors, the Trustee (irrespective of whether the 

  
 -43- 








 
principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for
the payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding or otherwise, 

(1) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of any
applicable series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Securities and any Coupons appertaining thereto 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 or counsel) and of the Holders of Securities or any Coupons appertaining thereto allowed in
such judicial proceeding, and 
 (2) to collect and receive any monies or other property payable or deliverable on any such
claims and to distribute the same subject to this Indenture; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder of Securities or any Coupons to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of
Securities or any Coupons, to pay to the Trustee any amount due to 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 6.6. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a
Security or any Coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or Coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding. 
  

	 	Section 5.5.	Trustee May Enforce Claims without Possession of Securities or Coupons. 

 All rights of
action and claims under this Indenture or any of the Securities or Coupons may be prosecuted and enforced by the Trustee without the possession of any of the Securities or Coupons 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 or judgment, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, shall be for the ratable benefit of each and every Holder of the Securities or Coupons in respect of which such judgment has been recovered. 
  

	 	Section 5.6.	Application of Money Collected. 

 Any money or other property 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 or other property on account of principal, or any premium, interest or Additional Amounts,
upon presentation of the Securities or Coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

SECOND: To the payment of the amounts then due and unpaid upon the Securities and any Coupons for principal and any premium,

principal and any premium, interest and Additional Amounts, respectively; 
 THIRD: The balance, if any, to the Person or
Persons entitled thereto or as a court of competent jurisdiction may direct. 
  

	 	Section 5.7.	Limitations on Suits. 

 No Holder of any Security of any series or any Coupons
appertaining thereto shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the
Securities of such series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding 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 such indemnity as is reasonably satisfactory to it against the costs,
expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity has failed to institute any such proceeding; and 
 (5) no direction inconsistent
with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of 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 or any Security to affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any other series, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any
right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 

  
 -45- 









	 	Section 5.8.	Unconditional Right of Holders to Receive Principal and any Premium, Interest and Additional Amounts. 


Notwithstanding any other provision in this Indenture, the Holder of any Security or Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of, any premium and (subject to Sections 3.5 and 3.7) interest on, and any Additional Amounts with respect to such Security or payment of such Coupon, as the case may be, on the respective Stated
Maturity or Maturities therefor specified in such Security or Coupon (or, in the case of redemption, on the Redemption Date or, in the case of repayment at the option of such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and to institute suit for the enforcement of any such payment, 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 of a Security or a
Coupon 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 each such Holder shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and each
such Holder shall continue as though no such proceeding had been instituted. 
  

	 	Section 5.10.	Rights and Remedies Cumulative. 

 Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security or a Coupon
is intended to be exclusive of any other right or remedy, and every right and remedy, to the extent permitted by law, shall 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, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy. 

 

	 	Section 5.11.	Delay or Omission Not Waiver. 

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

 

	 	Section 5.12.	Control by Holders of Securities.

Securities of such series and any Coupons appertaining thereto, provided that 

  
 -46- 








 (1) such direction shall not be in conflict with any rule of law or with this
Indenture or with the Securities of such series, 
 (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and 
 (3) such direction is not unduly prejudicial to the rights of the other
Holders of Securities of such series not joining in such action or that may involve the Trustee in personal liability. 
  

	 	Section 5.13.	Waiver of Past Defaults. 

 The Holders of not less than a majority in principal amount of
the Outstanding Securities of any series on behalf of the Holders of all the Securities of such series and any Coupons appertaining thereto may waive any past default hereunder with respect to such series and its consequences, except a default 

(1) in the payment of the principal of, any premium or interest on, or any Additional Amounts with respect to, any Security of
such series or any Coupons appertaining thereto, or 
 (2) in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
 The Company
may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to waive any past default hereunder. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only
such Persons, shall be entitled to waive any default hereunder, or to retract (prior to the requisite percentage for such waiver to become effective having been obtained) any such waiver previously given, whether or not such Holders remain Holders
after such record date; provided, that such waiver shall be effected no later than the 90th day after such record date. 
 Upon any
such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any
right consequent thereon. 
  

	 	Section 5.14.	Waiver of Usury, Stay or Extension Laws. 

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

  
 -47- 









	 	Section 5.15.	Undertaking for Costs 

 All parties to this Indenture agree, and each Holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party
litigant in such suit having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 5.15 shall not apply to any suit instituted by the Trustee, to any suit instituted by
any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any)
or interest, if any, on or Additional Amounts, if any, with respect to any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date, and, in the case of
repayment, on or after the date for repayment) or for the enforcement of the right, if any, to convert or exchange any Security into Common Stock or other securities in accordance with its terms.

the Company. If the instrument of acceptance by a successor Trustee required by Section 6.9 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court
of competent jurisdiction for the appointment of a successor Trustee with respect to such series. 
 (3) The Trustee may be
removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and the Company. 

(4) If at any time:

the Company or any such Holder, or 
 (c) 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 or pursuant to a Board Resolution, may remove the Trustee with respect to all Securities or

shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of
such series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any
particular series) and shall comply with the applicable requirements of Section 6.9. If, within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any
series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section 6.9, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no
successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders of Securities and accepted appointment in the manner required by Section 6.9, any Holder of a Security who has been a bona
fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of
such series. 
 (6) The Company shall give notice of each resignation and each removal of the Trustee with respect to the
Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series by mailing written notice of such event by first-class mail, postage prepaid, to the Holders of Registered Securities, if any, of such
series as their names and addresses appear in the Security Register and, if Securities of such series are issued as Bearer Securities, by publishing notice of such event once in an Authorized Newspaper in each Place of Payment located outside the
United States. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 

(7) In no event shall any retiring Trustee be liable for the acts or omissions of any successor Trustee hereunder. 

 

	 	Section 6.9.	Acceptance of Appointment by Successor.

hereunder of any successor Trustee with respect to all Securities, such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and 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 hereunder


  
 -53- 








 
of the retiring Trustee; but, on the request of the Company or such successor Trustee, such retiring Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to

 (2) Upon the appointment hereunder of any
successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and such successor Trustee 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, such successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee,
and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee
and that no Trustee shall be responsible for any notice given to, or received by, or any act or failure to act on the part of any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture, the resignation or
removal of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in
the Trustee under this Indenture with respect to the Securities of that or those series to which the appointment of such successor Trustee relates other than as hereinafter expressly set forth, 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 with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the
Company or such successor Trustee, such retiring Trustee, upon payment of its charges with respect to the Securities of that or those series to which the appointment of such successor Trustee relates and subject to Section 10.3 shall duly
assign, transfer and deliver to such successor Trustee, to the extent contemplated by such supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, subject to its claim, if any, provided for in Section 6.6. 
 (3) Upon
request of any Person appointed hereunder as a 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 (1) or (2) of this Section, as the case may be.

 (4) No Person shall accept its appointment hereunder as a successor Trustee
unless at the time of such acceptance such successor Person shall be qualified and eligible under this Article. 
  

	 	Section 6.10.	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, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities. 
  

	 	Section 6.11.	Appointment of Authenticating Agent. 

 The Trustee may appoint one or more Authenticating
Agents acceptable to the Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon original issue, exchange, registration of
transfer, partial redemption or partial repayment or pursuant to Section 3.6, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. 

Each Authenticating Agent must be acceptable to the Company and, except as provided in or pursuant to this Indenture, shall at all times be a
corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act, is authorized under applicable law and by its charter to act as an Authenticating Agent and has a combined
capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect specified in this Section. 
 Any Corporation into which an Authenticating
Agent may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Corporation succeeding to all or
substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, provided such Corporation shall be otherwise eligible to be an Authenticating
Agent under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 

  
 -55- 








 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a notice of resignation or upon such a termination, or in
case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall (i) mail
written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security
Register, and (ii) if Securities of the series are issued as Bearer Securities, publish notice of such appointment at least once in an Authorized Newspaper in the place where such successor Authenticating Agent has its principal office if such
office is located outside the United States. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally
named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 

The Company agrees to pay each Authenticating Agent from time to time reasonable compensation for its services under this Section. If the
Trustee makes such payments, it shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.6. 
 The
provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to each Authenticating Agent. 
 If an Authenticating Agent is appointed with
respect to one or more series of Securities pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication
in substantially the following form: 
 This is one of the Securities of the series designated herein referred to in the
within-mentioned Indenture. 
  

			
	 [NAME OF TRUSTEE],
          as Trustee

		
	By

	By	 	  

		 	Authorized Officer


 If all of the Securities of any series may not be originally issued at one time, and if the Trustee does
not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested in writing by
the Company (which writing need not be accompanied by or contained in an Officers’ Certificate by the Company), shall appoint in accordance with this Section an Authenticating Agent having an office in a Place of Payment designated by the
Company with respect to such series of Securities.

however, that if the Securities of such series are listed on The Stock Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock
exchange shall so require, the Company shall maintain a Paying Agent in London, Luxembourg or any other required city located outside the United States, as the case may be, so long as the Securities of such series are listed on such exchange. The
Company will give prompt written notice to the Trustee of the location, and any change in the location, of such Office or Agency. If at any time the Company shall fail to maintain any such required Office or Agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of such series and any Coupons appertaining thereto may be
presented and surrendered for payment at the place specified for the purpose with respect to such Securities as provided in or pursuant to this Indenture, and the Company hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands. 
 Except as otherwise provided in or pursuant to this Indenture, no payment of principal, premium,
interest or Additional Amounts with respect to Bearer Securities shall be made at any Office or Agency in the United States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the
United States; provided, however, if amounts owing with respect to any Bearer Securities shall be payable in Dollars, payment of 

  
 -64- 








 
principal of, any premium or interest on and any Additional Amounts with respect to any such Security may be made at a designated Corporate Trust Office of the Trustee or any Office or Agency
designated by the Company in the Borough of Manhattan, The City of New York, if (but only if) payment of the full amount of such principal, premium, interest or Additional Amounts at all offices outside the United States maintained for such purpose
by the Company in accordance with this Indenture is illegal or effectively precluded by exchange controls or other similar restrictions. 

The Company may also from time to time designate one or more other Offices or Agencies where the Securities of one or more series may
be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an
Office or Agency in each Place of Payment for Securities of any series for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other Office or
Agency. Unless otherwise provided in or pursuant to this Indenture, the Company hereby designates as the Place of Payment for each series of Securities Minneapolis, Minnesota, and initially appoints the office of the Trustee at Wells Fargo Bank,
National Association, Corporate Trust Operations, 608 Second Avenue South, N9303-121, Minneapolis, Minnesota 55479 as the Office or Agency for the purposes set forth in the first paragraph of this Section 10.2. 

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, if and so long as the Securities of any series
(i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Company will maintain with respect to each such series of
Securities, or as so required, at least one exchange rate agent. 
  

	 	Section 10.3.	Money for Securities Payments to Be Held in Trust. 

 If the Company shall at any time act
as its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of the principal of, any premium or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall
promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents for any series
of Securities, it shall, on or prior to each due date of the principal of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum (in the currency or currencies,
currency unit or units or composite currency or currencies described in the preceding paragraph) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the
Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 

  
 -65- 








 The Company shall cause each Paying Agent for any series of Securities other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall: 

(1) hold all sums held by it for the payment of the principal of, any premium or interest on or any Additional Amounts with
respect to 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 provided in or pursuant to this Indenture; 

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the
making of any payment of principal, any premium or interest on or any Additional Amounts with respect to the 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 terms 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 sums. 

Except as otherwise provided herein or pursuant hereto and subject to any applicable escheat and abandoned property laws, 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, any premium or interest on or any Additional Amounts with respect to any Security of any series or any Coupon appertaining
thereto and remaining unclaimed for two years after such principal or any such premium or interest or any such Additional Amounts shall have become due and payable shall be paid to the Company on Company Request, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Security or any Coupon appertaining thereto shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense
of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of Registered Securities of such series, or both, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of such publication or mailing nor shall it be later than two years after such principal and any premium or interest or Additional Amounts shall have become due and payable,
any unclaimed balance of such money then remaining will be repaid to the Company. 

  
 -66- 









	 	Section 10.4.	Additional Amounts. 

 If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any Coupon appertaining thereto Additional Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this Indenture there is mentioned, in any
context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or any Coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such
terms, and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding the payment of Additional Amounts in those provisions hereof where such express mention is not made. 

Except as otherwise provided in or pursuant to this Indenture or the Securities of the applicable series, if the Securities of a series
provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which
a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company shall
furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if any,
or interest on the Securities of such series shall be made to Holders of Securities of such series or the Coupons appertaining thereto who are United States Aliens without withholding for or on account of any tax, assessment or other governmental
charge described in the Securities of such series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities or
Coupons, and the Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against,
any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant to this
Section. 
  

	 	Section 10.5.	Limitation on Liens. 

 The Company agrees that it will not, and will not permit any
Restricted Subsidiary to, create, incur, issue, assume or guarantee any indebtedness for money borrowed (“Debt”), secured by a Mortgage upon any Operating Property, or upon shares of capital stock or Debt issued by any Restricted
Subsidiary and owned by the Company or any Restricted Subsidiary, at the date of this Indenture or hereafter acquired, without effectively providing concurrently that the Outstanding Securities hereunder (together with, if the Company shall so
determine, any other Debt of the Company or such Restricted Subsidiary then existing or thereafter created which is not subordinate to the Securities) shall be secured equally and ratably with or at the option of the Company, prior to such Debt so
long as such Debt shall be so secured, unless, at the time of such 

  
 -67- 








 
creation, incurrence, issuance, assumption or guarantee, after giving effect thereto and to the retirement of any Debt which is concurrently being retired, the aggregate amount of all such
Debt secured by Mortgages which would otherwise be subject to such restrictions (other than any Debt secured by Mortgages permitted in Clauses (1) through (7) of this Section 10.5), together with all Attributable Debt with respect to
Sale and Leaseback Transactions (other than certain Sale and Leaseback Transactions that are permitted under paragraph (b) of Section 10.6 below) would not exceed 15% of Consolidated Net Tangible Assets; provided, however, that this
Section shall not apply to, and there shall be excluded from Debt in any computation under this Section, Debt secured by: 

(1) Mortgages on property existing at the time of the acquisition thereof; 

(2) Mortgages on property of a Corporation or other entity existing at the time such Corporation or other 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 such Corporation or other entity (or a division thereof) as an entirety or substantially as an entirety to the
Company or a Restricted Subsidiary, provided that any such Mortgage does not extend to any property owned by the Company or Restricted Subsidiary immediately prior to such merger, consolidation, sale, lease or disposition; 

(3) Mortgages on property of a corporation or other entity existing at the time such corporation becomes a Restricted
Subsidiary; 
 (4) Mortgages in favor of the Company or a Restricted Subsidiary; 

(5) Mortgages to secure all or part of the cost of acquisition, construction, development or improvement of the underlying
property, or to secure Debt incurred to provide funds for any such purpose, provided that the commitment of the creditor to extend the credit secured by any such Mortgage shall have been obtained not later than 365 days after the later of
(A) the completion of the acquisition, construction, development or improvement of such property or (B) the placing in operation of such property; 

(6) Mortgages in favor of the United States of America or any State thereof, or any department, agency or instrumentality or
political subdivision thereof, to secure partial, progress, advance or other payments; and 
 (7) Mortgages existing on the
date of this Indenture or any extension, renewal, replacement or refunding of any Debt secured by a Mortgage existing on the date of this Indenture or referred to in clauses (1) to (3) or (5) of this Section 10.5, provided
that the principal amount of Debt secured thereby and not otherwise authorized by clauses (1) to (3) or (5) shall not exceed the principal amount of Debt, plus any premium or fee payable in connection with any such extension, renewal,
replacement or refunding, so secured at the time of such extension, renewal, replacement or refunding.

	 	Section 10.6.	Limitation on Sale and Leaseback 

 (a) The Company agrees that it will
not, and will not permit any Restricted Subsidiary to enter into any arrangement with any person providing for the leasing by the Company or any Restricted Subsidiary of any Operating Property that 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 (a “Sale and Leaseback Transaction”), unless the terms of such sale or transfer have been determined by the Board of
Directors to be fair and arm’s-length and either: 
 (i) within 180 days after the receipt of the proceeds of the sale
or transfer, the Company or any Restricted Subsidiary applies an amount equal to the greater of the net proceeds of the sale or transfer or the fair value of such Operating Property at the time of such sale or transfer to the prepayment or
retirement (other than any mandatory prepayment or retirement) of Senior Funded Debt; or 
 (ii) the Company or such
Restricted Subsidiary would be entitled, at the effective date of the sale or transfer, to incur Debt secured by a Mortgage on such Operating Property, in an amount at least equal to the Attributable Debt in respect of the Sale and Leaseback
Transaction, without equally and ratably securing the Securities pursuant to Section 10.5. 
 (b) The foregoing
restriction in paragraph (a) above will not apply to any Sale and Leaseback Transaction (i) for a term of not more than three years including renewals or (ii) between the Company and a Restricted Subsidiary or between Restricted
Subsidiaries, provided that the lessor shall be the Company or a wholly-owned Restricted Subsidiary. 
  

	 	Section 10.7.	Corporate Existence. 

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

	 	Section 10.8.	Waiver of Certain Covenants. 

 The Company may omit in any particular instance to comply
with any term, provision or condition set forth in Sections 10.5 or 10.6 with respect to the Securities of any series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such
series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 

  
 -69- 









	 	Section 10.9.	Company Statement as to Compliance; Notice of Certain Defaults. 

 (1) The
Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, a written statement (which need not be contained in or accompanied by an Officers’ Certificate) signed by the principal executive officer, the principal
financial officer or the principal accounting officer of the Company, stating that 
 (a) a review of the activities of the
Company during such year and of its performance under this Indenture has been made under his or her supervision, and 
 (b)
to the best of his or her knowledge, based on such review, (a) the Company has complied with all the conditions and covenants imposed on it under this Indenture throughout such year, or, if there has been a default in the fulfillment of any
such condition or covenant, specifying each such default known to him or her and the nature and status thereof, and (b) no event has occurred and is continuing which is, or after notice or lapse of time or both would become, an Event of
Default, or, if such an event has occurred and is continuing, specifying each such event known to him and the nature and status thereof. 

(2) The Company shall deliver to the Trustee, within five Business Days after becoming aware of the occurrence thereof, written
notice of any Event of Default or any event which after notice or lapse of time or both would become an Event of Default pursuant to clause (4) of Section 5.1. 

(3) The Trustee shall have no duty to monitor the Company’s compliance with the covenants contained in this Article 10
other than as specifically set forth in this Section 10.9. 
 ARTICLE 11 

REDEMPTION OF SECURITIES 

 

	 	Section 11.1.	Applicability of Article. 

 Redemption of Securities of any series at the option of the
Company as permitted or required by the terms of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article. 

 

	 	Section 11.2.	Election to Redeem; Notice to Trustee. 

 The election of the Company to redeem any
Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company of (a) less than all of the Securities of any series or (b) all of the Securities of any series, with the same
issue date, interest rate or formula, Stated Maturity and other terms, the Company shall, at least 60 

  
 -70- 








 
days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of
Securities of such series to be redeemed. 
  

	 	Section 11.3.	Selection by Trustee of Securities to be Redeemed. 

 If less than all of the
Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days and not less than 30 days prior to the
Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of
the principal amount of Registered Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than the minimum
denomination for a Security of such series established herein or pursuant hereto. 
 The Trustee shall promptly notify the Company
and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall
relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which has been or is to be redeemed. 

Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption
is converted into Common Stock or exchanged for other securities in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far
as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 

 

	 	Section 11.4.	Notice of Redemption. 

 Notice of redemption shall be given in the manner provided in
Section 1.6, not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the
manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other
Securities or portion thereof. 
 Any notice that is mailed to the Holder of any Registered Securities in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not such Holder receives the notice. 

  
 -71- 








 All notices of redemption shall state: 

(1) the Redemption Date, 

(2) the Redemption Price, 

(3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial
redemption, the principal amount) of the particular Security or Securities to be redeemed, 
 (4) in case any Security is to
be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of
authorized denominations for the principal amount thereof remaining unredeemed, 
 (5) that, on the Redemption Date, the
Redemption Price shall become due and payable upon each such Security or portion thereof to be redeemed, and, if applicable, that interest thereon shall cease to accrue on and after said date, 

(6) the place or places where such Securities, together (in the case of Bearer Securities) with all Coupons appertaining
thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts pertaining thereto, 

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

(8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must
be accompanied by all Coupons maturing subsequent to the date fixed for redemption or the amount of any such missing Coupon or Coupons will be deducted from the Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee
and any Paying Agent is furnished, 
 (9) if Bearer Securities of any series are to be redeemed and no Registered Securities
of such series are to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not subject to redemption on the Redemption Date pursuant to Section 3.5 or otherwise, the last date, as determined by the Company, on
which such exchanges may be made, 
 (10) in the case of Securities of any series that are convertible into Common Stock or
exchangeable for other securities, the conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate and the place or places
where such Securities may be surrendered for conversion or exchange, and 
 (11) the CUSIP number and/or similar numbers of
such Securities, if any (or any other numbers used by a Depositary to identify such Securities). 

  
 -72- 








 A notice of redemption published as contemplated by Section 1.6 need not identify particular
Registered Securities to be redeemed. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by
the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. 
  

	 	Section 11.5.	Deposit of Redemption Price. 

 On or prior to any Redemption Date, the Company shall
deposit, with respect to the Securities of any series called for redemption pursuant to Section 11.4, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in
Section 10.3) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 3.1 or in the
Securities of such series) any accrued interest on and Additional Amounts with respect thereto, all such Securities or portions thereof which are to be redeemed on that date. 
  


	 	Section 11.6.	Securities Payable on Redemption Date. 

 Notice of redemption having been given as
aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest and the Coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest and
Additional Amounts to the Redemption Date; provided, however, that, except as otherwise provided in or pursuant to this Indenture or the Bearer Securities of such series, installments of interest on Bearer Securities whose Stated Maturity is
on or prior to the Redemption Date shall be payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency located outside the United States except as otherwise provided in Section 10.2), and provided,
further, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 3.7. 

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a


  
 -73- 








 
deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that any interest or Additional Amounts
represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or Agency for such Security located outside of the United States except as otherwise provided in Section 10.2. 

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid,
shall bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
  

	 	Section 11.7.	Securities Redeemed in Part. 

 Any Registered Security which is to be redeemed only in
part shall be surrendered at any Office or Agency for such Security (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same
series, containing identical terms and provisions, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a
Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depositary or other Depositary for such Security in global form as shall be specified in the Company Order with respect
thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered. 

ARTICLE 12 

SINKING FUNDS 
  

	 	Section 12.1.	Applicability of Article. 

 The provisions of this Article shall be applicable to any
sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture. 

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a
“mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of such series is herein referred to as an “optional sinking fund payment”. If provided for by the terms
of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series and this Indenture. 

  
 -74- 









	 	Section 12.2.	Satisfaction of Sinking Fund Payments with Securities. 

 The Company may, in satisfaction
of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities, accompanied by a written notice to the Trustee, (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company), together in the case of any Bearer Securities of such series with all unmatured Coupons
appertaining thereto, and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking
fund payments pursuant to the terms of such Securities, provided that such series of Securities have not been previously so credited, Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If, as a result of the delivery or credit of Securities of any series in lieu of cash
payments pursuant to this Section 12.2, the principal amount of Securities of such series to be redeemed in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such series for
redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the
request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having
an unpaid principal amount equal to the cash payment requested to be released to the Company. 
  

	 	Section 12.3.	Redemption of Securities for Sinking Fund. 

 Not less than 75 days prior to each sinking
fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory 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 of Securities of that series pursuant to Section 12.2, and the optional amount, if any,
to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be
added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund payment date the Trustee shall select the Securities
to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.4. Such
notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.6 and 11.7.

	 	Section 13.1.	Applicability of Article. 

 Securities of any series which are repayable at the option of
the Holders thereof before their Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 13.1, in connection with any repayment of Securities, the Company may arrange for the
purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less
than the repayment price payable by the Company on repayment of such Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such
purchasers. 
 ARTICLE 14 

SECURITIES IN FOREIGN CURRENCIES 

 

	 	Section 14.1.	Applicability of Article. 

 Whenever this Indenture provides for (i) any action by,
or the determination of any of the rights of, Holders of Securities of any series in which not all of such Securities are denominated in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to this Indenture or the Securities, any amount in respect of any Security denominated in a Currency other than Dollars shall be treated for any such action or distribution as
that amount of Dollars that could be obtained for such amount on such reasonable basis of exchange and as of the record date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or,
if there shall be no applicable record date, such other date reasonably proximate to the date of such action, determination of rights or distribution) as the Company may specify in a written notice to the Trustee.

	 	Section 15.2.	Call, Notice and Place of Meetings. 

 (1) The Trustee may at any time
call a meeting of Holders of Securities of any series for any purpose specified in Section 15.1, to be held at such time and at such place in the Borough of Manhattan, The City of New York, or, if Securities of such series have been issued in
whole or in part as Bearer Securities, in London or in such place outside the United States as the Trustee shall determine. Notice of every meeting of Holders of Securities of any series, setting forth the time and the place of such meeting and in
general terms the action proposed to be taken at such meeting, shall be given, in the manner provided in Section 1.6, not less than 21 nor more than 180 days prior to the date fixed for the meeting. 

(2) In case at any time the Company (by or pursuant to a Board Resolution) or the Holders of at least 10% in principal amount
of the Outstanding Securities of any series shall have requested the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified in Section 15.1, by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee shall not have mailed notice of or made the first publication of the notice of such meeting within 21 days after receipt of such request (whichever shall be required pursuant to
Section 1.6) or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Company or the Holders of Securities of such series in the amount above specified, as the case may be, may determine the time and the
place in the Borough of Manhattan, The City of New York, or, if Securities of such series are to be issued as Bearer Securities, in London for such meeting and may call such meeting for such purposes by giving notice thereof as provided in clause
(1) of this Section. 
  

	 	Section 15.3.	Persons Entitled to Vote at Meetings. 

 To be entitled to vote at any meeting of Holders
of Securities of any series, a Person shall be (1) a Holder of one or more Outstanding Securities of such series, or (2) a Person appointed by an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities
of such series by such Holder or Holders. The only Persons who shall be entitled to be present or to speak at any meeting of Holders of Securities of any series shall be the Persons entitled to vote at such meeting and their counsel, any
representatives of the Trustee and its counsel and any representatives of the Company and its counsel. 
  

	 	Section 15.4.	Quorum; Action. 

 The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of Holders of Securities of such series. In the absence of a quorum within 30 minutes after the time appointed for any such meeting, the meeting shall, if convened at the
request of Holders of Securities of such series, be dissolved. In any other case the meeting may be adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence
of a 

  
 -77- 








 
quorum at any reconvened meeting, such reconvened meeting may be further adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of
such reconvened meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in Section 15.2(1), except that such notice need be given only once not less than five days prior to the date on which the meeting is
scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series which shall constitute a quorum. 

Except as limited by the proviso to Section 9.2, any resolution presented to a meeting or adjourned meeting duly reconvened at which a
quorum is present as aforesaid may be adopted only by the affirmative vote of the Holders of a majority in principal amount of the Outstanding Securities of that series; provided, however, that, except as limited by the proviso to
Section 9.2, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other Act which this Indenture expressly provides may be made, given or taken by the Holders of a specified percentage, which
is less than a majority, in principal amount of the Outstanding Securities of a series may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of such series. 
 Any resolution passed or decision taken at any
meeting of Holders of Securities of any series duly held in accordance with this Section shall be binding on all the Holders of Securities of such series and the Coupons appertaining thereto, whether or not such Holders were present or represented
at the meeting. 
  

	 	Section 15.5.	Determination of Voting Rights; Conduct and Adjournment of Meetings. 


(1) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of such series in regard to proof of the holding of Securities of such series and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 1.4 and the appointment of any proxy shall be proved in the manner specified in Section 1.4 or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 1.4 to certify to the holding of Bearer Securities. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and
genuine without the proof specified in Section 1.4 or other proof. 
 (2) The Trustee shall, by an instrument in
writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 15.2(2), in which case the Company or the Holders of Securities of the series
calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting. 

  
 -78- 








 (3) At any meeting, each Holder of a Security of such series or proxy shall be
entitled to one vote for each $1,000 principal amount of Securities of such series held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding
and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy. 

(4) Any meeting of Holders of Securities of any series duly called pursuant to Section 15.2 at which a quorum is present
may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting; and the meeting may be held as so adjourned without further notice. 

 

	 	Section 15.6.	Counting Votes and Recording Action of Meetings. 

 The vote upon any resolution submitted
to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall
make and file with the secretary of the meeting their verified written reports in triplicate of all votes cast at the meeting. A record, at least in triplicate, of the proceedings of each meeting of Holders of Securities of any series shall be
prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth
a copy of the notice of the meeting and showing that said notice was given as provided in Section 15.2 and, if applicable, Section 15.4. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive
evidence of the matters therein stated.
