		 	Authorized Officer


 SECTION 2.04. Debt Securities in Global Form. (a) If the Company shall establish
pursuant to Section 3.01 that the Debt Securities of a particular series are to be issued in whole or in part in the form of one or more Global Debt Securities, then the Company shall execute and the Trustee or its agent shall, in accordance
with Section 3.04 and the Company Order delivered to the Trustee or its agent thereunder, authenticate and deliver such Global Debt Security or Global Debt Securities, which (i) shall represent, and shall be denominated in an amount equal
to the aggregate principal amount of, the Outstanding Debt Securities of such series to be represented by such Global Debt Security or Global Debt Securities, or such portion thereof as the Company shall specify in a Company Order, (ii) shall
be registered in the name of the Depository for such Global Debt Security or Global Debt Securities or its nominee, (iii) shall be delivered by the Trustee or its agent to the Depository or pursuant to the Depository’s instruction and

certificate issued is registered in the name of the nominee of the Depository or in such other name as is requested by an authorized representative of the Depository (and any payment is made to the nominee of the Depository or 

  

 10 








 
to such other entity as is requested by an authorized representative of the Depository), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY
OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, the nominee of the Depository, has an interest herein.” 
 (b)
Notwithstanding any other provision of this Section 2.04 or of Section 3.06, and subject to the provisions of paragraph (c) below, unless the terms of a Global Debt Security expressly permit such Global Debt Security to be exchanged
in whole or in part for individual certificates representing Debt Securities, a Global Debt Security may be transferred, in whole but not in part and in the manner provided in Section 3.06, only to a nominee of the Depository for such Global
Debt Security, or to the Depository, or a successor Depository for such Global Debt Security selected or approved by the Company, or to a nominee of such successor Depository. 
 (c) (1) If at any time the Depository for a Global Debt Security notifies the Company that it is unwilling or unable to continue as Depository for such
Global Debt Security or if at any time the Depository for the Global Debt Securities for such series shall no longer be eligible or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation,
the Company shall appoint a successor Depository with respect to such Global Debt Security. If a successor Depository for such Global Debt Security is not appointed by the Company within 90 days after the Company receives notice or becomes aware of
such ineligibility, the Company will execute, and the Trustee or its agent, upon receipt of a Company Request for the authentication and delivery of certificates representing Debt Securities of such series in exchange for such Global Debt Security,
will authenticate and deliver, certificates representing Debt Securities of such series of like tenor and terms in an aggregate principal amount equal to the principal amount of the Global Debt Security in exchange for such Global Debt Security.

 (2) The Company may at any time and in its sole discretion determine that the Debt Securities of any series or portion thereof issued or
issuable in the form of one or more Global Debt Securities shall no longer be represented by such Global Debt Security or Global Debt Securities. In such event the Company will execute, and the Trustee, upon receipt of a Company Request for the
authentication and delivery of certificates representing Debt Securities of such series in exchange in whole or in part for such Global Debt Security, will authenticate and deliver certificates representing Debt Securities of such series of like
tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such Global Debt Security or Global Debt Securities representing such series or portion thereof in exchange for such Global Debt Security or Global
Debt Securities. 
 (3) If specified by the Company pursuant to Section 3.01 with respect to Debt Securities issued or issuable in the
form of a Global Debt Security, the Depository for such Global Debt Security may surrender such Global Debt Security in exchange in whole or in part for certificates representing Debt Securities of such series of like tenor and terms in definitive
form on such terms as are acceptable to the Company and such Depository. Thereupon the Company shall execute, and the Trustee or its agent shall authenticate and deliver, without a service charge, (A) to each Holder specified by the Debt
Security Registrar or the Depository a certificate or certificates representing Debt Securities of the same series of like tenor and terms and of any authorized denomination as requested by such person in an aggregate principal 

  

 11 








 
amount equal to and in exchange for such Holder’s beneficial interest as specified by the Debt Security Registrar or the Depository in the Global Debt
Security; and (B) to such Depository a new Global Debt Security of like tenor and terms and in an authorized denomination equal to the difference, if any, between the principal amount of the surrendered Global Debt Security and the aggregate
principal amount of certificates representing Debt Securities delivered to Holders thereof. 
 (4) In any exchange provided for in any of the
preceding three paragraphs, the Company will execute and the Trustee or its agent will authenticate and deliver certificates representing Debt Securities in definitive registered form in authorized denominations for Debt Securities of the same
series or any integral multiple thereof. Upon the exchange of the entire principal amount of a Global Debt Security for certificates representing Debt Securities, such Global Debt Security shall be cancelled by the Trustee or its agent. Except as
provided in the preceding paragraph, certificates representing Debt Securities issued in exchange for a Global Debt Security pursuant to this Section shall be registered in such names and in such authorized denominations for Debt Securities of that
series or any integral multiple thereof, as the Debt Security Registrar or Depository shall instruct the Trustee or its agent. The Trustee or the Debt Security Registrar shall deliver at its Corporate Trust Office such certificates representing Debt
Securities to the Holders in whose names such Debt Securities are so registered. 
 ARTICLE 3. 
 THE DEBT SECURITIES. 
 SECTION 3.01.

 The Debt Securities may be issued in one or more series. All Debt Securities of
each series issued under this Indenture shall in all respects be equally and ratably entitled to the benefits hereof with respect to such series without preference, priority or distinction on account of the actual time or times of the authentication
and delivery or maturity of the Debt Securities of such series. There shall be established in or pursuant to a Board Resolution, and set forth in an Officers’ Certificate to the extent not established in a Board Resolution, or established in
one or more indentures supplemental hereto, prior to the issuance of Debt Securities of any series: 
 (a) the title of the Debt Securities

aggregate principal amount of the Debt Securities of the series which may be authenticated and delivered under this Indenture (except for Debt Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu
of, other Debt Securities of that series pursuant to this Article Three, the second paragraph of Section 4.03, or Section 11.04); 
 (c) the date or dates (or the manner of calculation thereof) on which the principal of the Debt Securities of the series is payable;

(e) the Place of Payment; 
 (f) the
period or periods within which, the price or prices at which, the currency or currency units in which, and the terms and conditions upon which Debt Securities of the series may be redeemed, in whole or in part, at the option of the Company;

 (g) the obligation, if any, of the Company to redeem or purchase Debt Securities of the series pursuant to any sinking fund or analogous
provisions or at the option of a Holder thereof and the period or periods within which, the price or prices in the currency at which, the currency or currency units in which, and the terms and conditions upon which Debt Securities of the series
shall be redeemed or purchased, in whole or in part, pursuant to such obligation; 
 (h) the denominations in which the Debt Securities of
such series shall be issuable if other than denominations of $1,000 and any integral multiple thereof; 
 (i) if other than Dollars, the
currencies in which payments of interest or principal of (and premium, if any, with respect to) the Debt Securities of the series are to be made; 
 (j) if the interest on or principal of (or premium, if any, with respect to) the Debt Securities of the series are to be payable, at the election of the Company or a Holder thereof or otherwise, in a currency other than that in which such
Debt Securities are payable, the period or periods within which, and the other terms and conditions upon which, such election may be made, and the time and manner of determining the exchange rate between the currency in such Debt Securities are
denominated or stated to be payable and the currency in which such Debt Securities or any of them are to be so payable; 
 (k) whether the
amount of payments of interest on or principal of (or premium, if any, with respect to) the Debt Securities of such series may be determined with reference to an index, formula or other method (which index, formula or method or method may be based,
without limitation, on one or more currencies, commodities, equity indices or other indices), and, if so, the terms and conditions upon which and the manner in which such amounts shall be determined and paid or payable; 
 (l) the extent to which any Debt Securities will be issuable in permanent global form, the manner in which any payments on a permanent global Debt
Security will be made, and the appointment of any Depository relating thereto; 
 (m) any deletions from, modifications of or additions to

 13 








 (n) if any of the Debt Securities of such series are to be issuable upon the exercise of warrants, this
shall be so established as well as the time, manner and place for such Debt Securities to be authenticated and delivered; and 
 (o) any
other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture). 
 All Debt Securities of any one
series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to such Board Resolution and set forth in such Officers’ Certificate or in any such indenture supplemental hereto.

 SECTION 3.02. Denominations. The Debt Securities of each series shall be issuable in registered form without coupons in such
denominations as shall be specified as contemplated in Section 3.01. In the absence of any specification with respect to the Debt Securities of any series, the Debt Securities of such series shall be issuable in denominations of $1,000 and any
integral multiple thereof, which may be in Dollars or any Foreign Currency. 
 SECTION 3.03. Payment of Principal and Interest. The
principal of, premium, if any, and interest on the Debt Securities shall be payable at the office or agency of the Company designated for that purpose in the Place of Payment, as provided in Section 5.02; provided, however, that interest may be
payable at the option of the Company by check mailed to the address of the Person entitled thereto as such address shall appear on the Debt Security Register on the Regular Record Date for such interest payment. 
 SECTION 3.04. Execution of Debt Securities. The Debt Securities shall be executed manually or by facsimile in the name and on behalf of the
Company by its Chief Executive Officer, its President, its Executive Vice President, its Chief Financial Officer, or its Treasurer. Only such Debt Securities as shall bear thereon a certificate of authentication substantially in the form
hereinbefore recited, manually executed by the Trustee, shall be entitled to the benefits of this Indenture or be valid or become obligatory for any purpose. Such certificate by the Trustee upon any Debt Security executed by the Company shall be
conclusive evidence that the Debt Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture. 
 In case any officer of the Company who shall have executed any of the Debt Securities shall cease to be such officer before the Debt Securities so
executed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Debt Securities nevertheless shall be valid and binding and may be authenticated and delivered or disposed of as though the Person who executed
such Debt Securities had not ceased to be such officer of the Company; and any Debt Securities may be executed on behalf of the Company by such Persons as, at the actual date of the execution of such Debt Security, shall be the proper officers of
the Company, although at the date of such Debt Security or of the execution of this Indenture any such Person was not such an officer. 
 At
any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Debt Securities of any series, properly created in accordance with Section 3.01 and executed by the Company, to the Trustee for
authentication; and the Trustee shall 

  

 14 








 
authenticate and deliver such Debt Securities upon receipt of a Company Order. In the event that any other Person performs the Trustee’s duties as
Authenticating Agent pursuant to a duly executed agreement, the Company shall notify the Trustee in writing of the issuance of any Debt Securities hereunder, such notice to be delivered in accordance with the provisions of Section 15.03 on the
date such Debt Securities are delivered by the Company for authentication to such other Person. 
 Prior to any such authentication and
delivery, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, in addition to the Opinion of Counsel to be furnished to the Trustee pursuant to Sections 2.02 and 15.05 and the Officers’ Certificate relating to
the issuance of any series of Debt Securities pursuant to Sections 15.05 and 3.01, Opinions of Counsel stating that: 
 (a) all instruments
furnished to the Trustee conform to the requirements of this Indenture and constitute sufficient authority hereunder for the Trustee to authenticate and deliver such Debt Securities; 
 (b) all laws and requirements with respect to the form and execution by the Company of the supplemental indenture, if any, have been complied with, the
execution and delivery of the supplemental indenture, if any, will not violate the terms of this Indenture, the supplemental indenture has been duly qualified under the Trust Indenture Act of 1939, the Company has corporate or company power to
execute and deliver any such supplemental indenture and has taken all necessary corporate action for those purposes and any such supplemental indenture has been executed and delivered and constitutes the legal, valid and binding obligation of the
Company enforceable in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights generally from time to time in effect);

 (c) the form and terms of such Debt Securities have been established in conformity with the provisions of this Indenture; and 

(d) all laws and requirements with respect to the execution and delivery by the Company of such Debt Securities have been complied with, the
authentication and delivery of the Debt Securities by the Trustee will not violate the terms of this Indenture, the Company has the corporate or company power to issue such Debt Securities and such Debt Securities, assuming due authentication and
delivery by the Trustee, constitute legal, valid and binding obligations of the Company in accordance with their terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other laws affecting
creditors’ rights generally from time to time in effect) and are entitled to the benefits of this Indenture, equally and ratably with all other Outstanding Debt Securities, if any, of such series. 
 The Trustee shall not be required to authenticate such Debt Securities if the issue thereof will adversely affect the Trustee’s own rights, duties
or immunities under the Debt Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee or such action would expose the Trustee to personal liability to existing Holders. 
  

 15 








 Unless otherwise provided in the form of Debt Security for any series, all Debt Securities shall be dated
the date of their authentication. 
 No Debt Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any
purpose, unless there appears on such Debt Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Debt Security shall be conclusive evidence,
and the only evidence, that such Debt Security has been duly authenticated and delivered hereunder. 
 SECTION 3.05. Temporary Debt
Securities. Pending the preparation of definitive Debt Securities of any series, the Company may execute, and upon receipt of the documents required by Sections 2.02, 3.01 and 3.04, together with a Company Order, the Trustee shall authenticate
and deliver, such temporary Debt Securities which may be printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denominations, substantially of the tenor of such definitive Debt Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such temporary Debt Securities may determine, as evidenced by their execution of such temporary Debt Securities. 
 If temporary Debt Securities of any series are issued, the Company will cause definitive Debt Securities of such series to be prepared without
unreasonable delay. After the preparation of definitive Debt Securities of any series, the temporary Debt Securities of such series shall be exchangeable for definitive Debt Securities of such series, upon surrender of the temporary Debt Securities
of such series at any office or agency maintained by the Company for such purposes as provided in Section 5.02, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Debt Securities of any series, the
Company shall execute and the Trustee shall authenticate and deliver in exchange therefore a like principal amount of definitive Debt Securities of such series having the same interest rate and Stated Maturity and bearing interest from the same date
of any authorized denominations. Until so exchanged the temporary Debt Securities of such series shall in all respects be entitled to the same benefits under this Indenture as definitive Debt Securities of such series. 
 SECTION 3.06. Exchange and Registration of Transfer of Debt Securities. Debt Securities may be exchanged for a like aggregate principal amount of
Debt Securities of such series that are of other authorized denominations. Debt Securities to be exchanged shall be surrendered at any office or agency to be maintained for such purpose by the Company, as provided in Section 5.02, and the
Company shall execute and the Trustee shall authenticate and deliver in exchange therefore the Debt Security or Debt Securities of authorized denominations which the Debt Security Holder making the exchange shall be entitled to receive. Each agent
of the Company appointed pursuant to Section 5.02 as a person authorized to register and register transfer of Debt Securities is sometimes herein referred to as a “Debt Security Registrar.” 
 The Company shall keep, at each such office or agency of the Company maintained for such purpose, as provided in Section 5.02, a register for each
series of Debt Securities hereunder (the registers of all Debt Security Registrars being herein sometimes collectively referred to as the “Debt Security Register”) in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for the registration of Debt Securities and shall register the 

  

 16 








 
transfer of Debt Securities as provided in this Article Three. At all reasonable times, such Debt Security Register shall be open for inspection by the
Trustee and any Debt Security Registrar other than the Trustee. Upon due presentment for registration of transfer of any Debt Security at any such office or agency, the Company shall execute and register and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new Debt Security or Debt Securities of authorized denominations for an equal aggregate principal amount. Registration or registration of transfer of any Debt Security by any Debt Security
Registrar in the registry books maintained by such Debt Security Registrar, and delivery of such Debt Security, duly authenticated, shall be deemed to complete the registration or registration of transfer of such Debt Security. 
 The Company will at all times designate one Person (who may be the Company and who need not be a Debt Security Registrar) to act as repository of a
master list of names and addresses of Holders of the Debt Securities. The Trustee shall act as such repository unless and until some other Person is, by written notice from the Company to the Trustee and each Debt Security Registrar, designated by
the Company to act as such. The Company shall cause each Debt Security Registrar to furnish to such repository, on a current basis, such information as such repository may reasonably request as to registrations, transfers, exchanges and other
transactions effected by such registrar, as may be necessary or advisable to enable such repository to maintain such master list on as current a basis as is reasonably practicable. 
 No Person shall at any time be appointed as or act as a Debt Security Registrar unless such Person is at such time empowered under applicable law to act
as such and duly registered to act as such under and to the extent required by applicable law and regulations. 
 All Debt Securities
presented to a Debt Security Registrar for registration of transfer shall be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and such Debt Security Registrar duly executed by
the registered Holder or such Holder’s attorney duly authorized in writing. 
 No service charge shall be made for any exchange or
registration of transfer of Debt Securities, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 
 The Company shall not be required to issue, exchange or register a transfer of (a) any Debt Securities of any series for a period of 15 days next
preceding the mailing of a notice of redemption of Debt Securities of such series and ending at the close of business on the day of the mailing of a notice of redemption of Debt Securities of such series so selected for redemption, or (b) any
Debt Securities selected, called or being called for redemption except, in the case of any Debt Security to be redeemed in part, the portion thereof not so to be redeemed. 
 All Debt Securities issued in exchange for or upon registration of transfer of Debt Securities shall be valid obligations of the Company, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the Debt Securities surrendered for such exchange or registration of transfer. 
  

 17 








 None of the Trustee, any agent of the Trustee, any paying agent or the Company 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 Debt Security or for maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. 
 SECTION 3.07. Mutilated, Destroyed, Lost or Stolen Debt Securities. In case any temporary or definitive Debt
Security shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its request the Trustee shall authenticate and deliver, a new Debt Security, bearing a number, letter or other distinguishing mark
not contemporaneously Outstanding, in exchange and substitution for the mutilated Debt Security, or in lieu of and in substitution for the Debt Security so destroyed, lost or stolen. In every case the applicant for a substituted Debt Security shall
furnish to the Company and to the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and to the Trustee
evidence to their satisfaction of the destruction, loss or theft, of such Debt Security and of the ownership thereof. 
 In the absence of
notice to the Trustee or the Company that such Debt Security has been acquired by a bona fide purchaser, the Trustee shall authenticate any such substituted Debt Security and deliver the same upon any Company Request. Upon the issuance of any
substituted Debt Security, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Debt Security which has
matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substituted Debt Security, pay or authorize the payment of the same (without surrender thereof except in the case of a
mutilated Debt Security) if the applicant for such payment shall furnish to the Company and to the Trustee such security or indemnity as may be required by them to save each of them harmless and, in case of destruction, loss or theft, evidence
satisfactory to the Company and to the Trustee of the destruction, loss or theft of such Debt Security and of the ownership thereof. 
 Every
substituted Debt Security issued pursuant to the provisions of this Section 3.07 by virtue of the fact that any Debt Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Debt Security shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debt Securities duly issued hereunder. All Debt Securities shall be
held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities and shall preclude (to the extent permitted by law) any and all
other rights or remedies with respect to the replacement or payment of negotiable instruments or other securities without their surrender. 
 SECTION 3.08. Payment of Interest; Interest Rights Preserved. Interest which is payable, and is punctually paid or duly provided for, on any Interest Payment Date, on any Debt Security, shall unless otherwise provided in such Debt
Security be paid to the Person in whose name the Debt Security (or one or more Predecessor Debt Securities) is registered at the close of business on the Regular Record Date for such interest.

 Unless otherwise stated in the form of Debt Security of a series, interest on the Debt Securities of any
series shall be computed on the basis of a 360 day year comprised of twelve 30 day months. 
 Any interest on any Debt Security which is
payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of
having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (a) or (b) below: 
 (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names any such Debt Securities (or their respective Predecessor Debt Securities) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Debt Security and the date
of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a
Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefore to be mailed, first-class postage prepaid, to each Holder of such Debt Securities, at such Holder’s address as it appears in the Debt Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefore having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names such Debt Securities (or their respective Predecessor Debt Securities) are
registered on such Special Record Date and shall no longer be payable pursuant to the following Clause (b). 
 (b) 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 the Debt Securities of that series 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. 
 Subject to the foregoing provisions of this Section, each Debt Security delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Debt Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Debt Security. 
 SECTION 3.09. Persons Deemed Owners. The
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Debt Security is registered as the owner of such Debt Security for the purpose of receiving payment of principal 

  

 19 








 
of, premium, if any, and (subject to Section 3.08) interest on, such Debt Security and for all other purposes whatsoever whether or not such Debt
Security be overdue, and neither the Company, the Trustee, nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 SECTION 3.10. Cancellation of Debt Securities Paid, etc. All Debt Securities surrendered for the purpose of payment, redemption, exchange or registration of transfer or delivered in satisfaction in whole or in part of any sinking
fund obligation shall, if surrendered to the Company or any agent of the Trustee or the Company under this Indenture, be delivered to the Trustee and promptly cancelled by it, or, if surrendered to the Trustee, shall be promptly cancelled by it, and
no Debt Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of cancelled Debt Securities in accordance with its customary procedures unless directed by a
Company Order. 
 SECTION 3.11. Currency and Manner of Payments. (a) With respect to Debt Securities denominated in Dollars or a
Foreign Currency, the following payment provisions shall apply: 
 (1) Except as provided in subparagraph (a)(2) or in paragraph (c) of
this Section 3.11, payment of principal of and premium, if any, on any Debt Securities will be made at the offices established pursuant to Section 5.02 by delivery of a check in the currency in which the Debt Security is denominated on the
payment date against surrender of such Debt Security, and any interest on any Debt Security will be paid at such office by mailing a check in the currency in which the Debt Securities were issued to the Person entitled thereto at the address of such
Person appearing on the Debt Security Register. 
 (2) Payment of the principal of and premium, if any, and interest on such Debt Security
may also, subject to applicable laws and regulations, be made at such other place or places as may be designated by the Company by any appropriate method. 
 (b) Not later than the fourth Business Day after the Regular Record Date for such Interest Payment Date, the paying agent will deliver to the Company a written notice specifying, in the currency in which each series
of the Debt Securities are denominated, the respective aggregate amounts of principal of and premium, if any, and interest on the Debt Securities to be made on such payment date, specifying the amounts so payable in respect of the Debt Securities.
The failure of the paying agent to deliver such notice shall not relieve the Company from its obligation to make all payments with respect to any Debt Security when due. 
 (c) If the Foreign Currency in which any of the Debt Securities are denominated ceases to be used both by the government of the country which issued such currency and for the settlement of transactions by public
institutions of or within the international banking community, then with respect to each date for the payment of Foreign Currency occurring after the last date on which the Foreign Currency was so used (the “Conversion Date”), the Dollar
shall be the currency of payment for use on each such Interest Payment Date. The Dollar amount to be paid by the Company to the Trustee and by the Trustee or any paying agent to the Holder of such Debt Securities with respect to such payment date
shall be the Dollar Equivalent of the Foreign Currency as determined by the Currency Determination Agent as of the second Business Day preceding the applicable payment date (the “Valuation Date”) in the manner provided in paragraph (d).

  

 20 








 (d) The “Dollar Equivalent of the Foreign Currency” shall be determined by the Currency
Determination Agent as of each Valuation Date and shall be obtained by converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the Valuation Date. 
 (e) The “Market Exchange Rate” shall mean, for any currency, the highest firm bid quotation for U.S. dollars received by the Currency
Determination Agent at approximately 11:00 a.m., New York City time, on the second Business Day preceding the applicable payment date (or, if no such rate is quoted on such date, the last date on which such rate was quoted), from three recognized
foreign exchange dealers in the City of New York selected by the Currency Determination Agent and approved by the Company (one of which may be the Currency Determination) for the purchase by the quoting dealer, for settlement on such payment date,
of the aggregate amount of such currency payable on such payment in respect of all Notes denominated in such currency. 
 (f) All decisions
and determinations of the Currency Determination Agent regarding the Dollar Equivalent of the Foreign Currency and the Market Exchange Rate shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes
and irrevocably binding upon the Company and all Holders of the Debt Securities. In the event that the Foreign Currency ceases to be used both by the government of the country which issued such currency and for the settlement of transactions by
public institutions of or within the international banking community, the Company, after learning thereof, will promptly give notice thereof to the Trustee (and the Trustee will promptly thereafter give notice in the manner provided in
Section 15.03 to the Holders) specifying the Conversion Date. 
 (g) The Trustee shall be fully justified and protected in relying on
and acting upon the information so received by it from the Company or the Currency Determination Agent and shall not otherwise have any duty or obligation to determine such information independently. 
 (h) If the principal of (and premium, if any) and interest on any Debt Securities is payable in a Foreign Currency and such Foreign Currency is not
available for payment due to the imposition of exchange controls or other circumstances beyond the control of the Company, then the Company shall be entitled to satisfy its obligations to Holders under this Indenture by making such payment in
Dollars on the basis of the Market Exchange Rate for such Foreign Currency on the latest date for which such rate was established on or before the date on which payment is due. Any payment made pursuant to this Section 3.11 in Dollars where the
required payment is in a Foreign Currency shall not constitute a default or Event of Default under this Indenture. 
 ARTICLE 4.

 REDEMPTION OF DEBT SECURITIES; SINKING FUNDS. 
 SECTION 4.01. Applicability of Article. The Company may reserve the right to redeem and pay before Stated Maturity all or any part of the Debt Securities of any series, either by optional redemption, sinking
fund (mandatory or optional) or otherwise, by provision therefor in the form of Debt Security for such series on such terms as are specified in such form or the 

  

 21 








 
Board Resolution or Officers’ Certificate delivered pursuant to Section 3.01 or the indenture supplemental hereto as provided in Section 3.01
with respect to Debt Securities of such series. Redemption of Debt Securities of any series shall be made in accordance with the terms of such Debt Securities and, to the extent that this Article does not conflict with such terms, in accordance with
this Article. 
 SECTION 4.02. Notice of Redemption; Selection of Debt Securities. In case the Company shall desire to exercise the
right to redeem all, or, as the case may be, any part of a series of Debt Securities pursuant to Section 4.01, the Company shall fix a date for redemption and the Company, or, at the Company’s request, the Trustee in the name of and at the
expense of the Company, shall mail a notice of such redemption at least 30 and not more than 60 days prior to the date fixed for redemption to the Holders of Debt Securities so to be redeemed as a whole or in part at their last addresses as the same
appear on the Debt Securities Register. Such mailing shall be by first class mail. The notice if mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any
case, failure to give such notice by mail or any defect in the notice to the Holder of any Debt Security designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Debt Security.

 Notice of redemption shall be given in the name of the Company and shall specify the date fixed for redemption, the Redemption Price at
which Debt Securities of any series are to be redeemed, the place of payment (which shall be at the offices or agencies to be maintained by the Company pursuant to Section 5.02), that payment of the Redemption Price will be made upon
presentation and surrender of such Debt Securities, that interest accrued to the date fixed for redemption will be paid as specified in said notice that on and after said date interest thereon or on the portions thereof to be redeemed will cease to
accrue, and the Section of this Indenture pursuant to which Debt Securities will be redeemed. In case less than all Debt Securities of any series are to be redeemed, the notice of redemption shall also identify the particular Debt Securities to be
redeemed as a whole or in part and shall state that the redemption is for the sinking fund, if such is the case. In case any Debt Security is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount
thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Debt Security, a new Debt Security or Debt Securities of such series in aggregate principal amount equal to the unredeemed portion thereof
will be issued without charge to the Holder. 
 If less than all the Debt Securities of any series are to be redeemed, the Company shall give
the Trustee notice, at least 45 days (or such shorter period acceptable to the Trustee) in advance of the date fixed for redemption, as to the aggregate principal amount of Debt Securities to be redeemed. Debt Securities may be redeemed in part in
multiples equal to the minimum authorized denomination for Debt Securities of such series or any multiple thereof. Thereupon the Trustee shall select, in such manner as in its sole discretion it shall deem appropriate and fair, the Debt Securities
or portions thereof to be redeemed, and shall as promptly as practicable notify the Company of the Debt Securities or portions thereof so selected. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to
the redemption of Debt Securities of any series shall relate, in the case of any Debt Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Debt Security which has been or is to be redeemed. 
  

 22 








 On or prior to the date fixed for redemption specified in the notice of redemption given as provided in
this Section 4.02, the Company will deposit with the Trustee or with the paying agent an amount of money in the currency in which the Debt Securities of such series are payable sufficient to redeem on the date fixed for redemption all the Debt
Securities so called for redemption at the appropriate Redemption Price, together with accrued interest to the date fixed for redemption. 
 The Trustee shall not mail any notice of redemption of any series of Debt Securities during the continuation of any default in payment of interest on any series of Debt Securities when due or of any Event of Default, except that where
notice of redemption with respect to any series of Debt Securities shall have been mailed prior to the occurrence of such default or Event of Default, the Trustee shall redeem such Debt Securities provided funds are deposited with it for such
purpose. 
 SECTION 4.03. Payment of Debt Securities Called for Redemption. If notice of redemption has been given as herein provided,
the Debt Securities or portions of Debt Securities with respect to which such notice has been given shall become due and payable on the date and at the place stated in such notice at the applicable Redemption Price, together with interest accrued to
the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Debt Securities or portions thereof at the Redemption Price, together with interest accrued to said date) interest on the Debt
Securities or portions of Debt Securities so called for redemption shall cease to accrue, and such Debt Securities and portions of Debt Securities shall be deemed not to be Outstanding hereunder and shall not be entitled to any benefit under this
Indenture except to receive payment of the Redemption Price, together with accrued interest to the date fixed for redemption. On presentation and surrender of such Debt Securities at the place of payment in said notice specified, the said Debt
Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable Redemption Price, together with interest accrued thereon to the date fixed for redemption; provided, however, that any installments of interest
becoming due on the date fixed for redemption shall be payable to the Holders of such Debt Securities, or one or more previous Debt Securities evidencing all or a portion of the same debt as that evidenced by such particular Debt Securities,
registered as such on the relevant record dates according to their terms and the provisions of Section 3.08. 
 Upon presentation and
surrender of any Debt Security redeemed in part only, with, if the Company or the Trustee so required, 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 such Holder’s attorney duly authorized in writing, the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Debt Security or Debt Securities of the same series
having the same interest rate and Stated Maturity and bearing interest from the same date, of any authorized denominations as requested by such Holder, in aggregate principal amount equal to the unredeemed portion of the Debt Security so presented
and surrendered. 
 SECTION 4.04. Exclusion of Certain Debt Securities from Eligibility for Selection for Redemption. Debt Securities
shall be excluded from eligibility for selection for redemption if they are identified by registration and certificate number in a written statement signed by a 

  

 23 








 
Responsible Officer of the Company and delivered to the Trustee at least 45 days prior to the last date on which notice of redemption may be given as being
owned of record and beneficially by, and not pledged or hypothecated by, either (a) the Company or (b) an entity specifically identified in such written statement directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company. 
 SECTION 4.05. Provisions with Respect to any Sinking Funds. Unless the form or terms of
any series of Debt Securities shall provide otherwise, in lieu of making all or any part of any mandatory sinking fund payment with respect to such series of Debt Securities in cash, the Company may at its option (a) deliver to the Trustee for
cancellation any Debt Securities of such series theretofore acquired by the Company, or (b) receive credit for any Debt Securities of such series (not previously so credited) acquired by the Company and theretofore delivered to the Trustee for
cancellation, then Debt Securities so delivered or credited shall be credited at the applicable sinking fund Redemption Price with respect to the Debt Securities of such series. 
 On or before the 45th day next preceding each sinking fund Redemption Date, the Company will deliver to the Trustee a certificate signed by the Chief
Financial Officer or the Treasurer of the Company specifying (i) the portion of the mandatory sinking fund payment to be satisfied by deposit of cash in the currency in which the Debt Securities of such series are payable, by delivery of Debt
Securities theretofore purchased or otherwise acquired by the Company (which Debt Securities shall accompany such certificate) and by credit for Debt Securities acquired by the Company and theretofore delivered to the Trustee for cancellation
redeemed by the Company and stating that the credit to be applied has not theretofore been so applied and (ii) whether the Company intends to exercise its right, if any, to make an optional sinking fund payment, and, if so, the amount thereof.
Such certificate shall also state that no Event of Default has occurred and is continuing. Such certificate shall be irrevocable and upon its delivery the Company shall be obligated to make the payment or payments therein referred to, if any, on or
before the next succeeding sinking fund payment date. In case of the failure of the Company on or before the 45th day next preceding each sinking fund Redemption Date to deliver such certificate (or to deliver the Debt Securities specified in this
paragraph), the sinking fund payment due on the next succeeding sinking fund payment date shall be paid entirely in cash (in the currency described above) and shall be sufficient to redeem the principal amount of Debt Securities as a mandatory
sinking fund payment, without the option to deliver or credit Debt Securities as provided in the first paragraph of this Section 4.05 and without the right to make an optional sinking fund payment as provided herein. 
 If the sinking fund payment or payments (mandatory or optional) with respect to any series of Debt Securities made in cash (in the currency described
above) shall exceed the minimum authorized denomination set forth in an Officers’ Certificate pursuant to Section 3.01 or the equivalent in the currency in which the Debt Securities of such series are payable (or a lesser sum if the
Company shall so request), unless otherwise provided by the terms of such series of Debt Securities, said cash shall be applied by the Trustee on the sinking fund Redemption Date with respect to Debt Securities of such series at the applicable
sinking fund Redemption Price with respect to Debt Securities of such series, together with accrued interest, if any, to the date fixed for redemption, with the effect provided in Section 4.03. The Trustee shall select, in the manner provided
in Section 4.02, for redemption on such sinking fund Redemption Date a sufficient principal amount of Debt Securities of such series to utilize said cash and shall 

  

 24 








 
thereupon cause notice of redemption of the Debt Securities of such series for the sinking fund to be given in the manner provided in Section 4.02 (and
with the effect provided in Section 4.03) for the redemption of Debt Securities in part at the option of the Company. Debt Securities of any series which are identified by registration and certificate number in an Officers’ Certificate at
least 45 days prior to the sinking fund Redemption Date as being beneficially owned by, and not pledged or hypothecated by, the Company or an entity directly or indirectly controlling or controlled by or under direct or indirect common control with
the Company shall be excluded from Debt Securities of such series eligible for selection for redemption. Any sinking fund moneys not so applied or allocated by the Trustee to the redemption of Debt Securities of such series shall be added to the
next cash sinking fund payment with respect to Debt Securities of such series received by the Trustee and, together with such payment, shall be applied in accordance with the provisions of this Section 4.05. Any and all sinking fund moneys with
respect to Debt Securities of any series held by the Trustee at the maturity of Debt Securities of such series, and not held for the payment or redemption of particular Debt Securities of such series, shall be applied by the Trustee, together with
other moneys, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Debt Securities of such series at maturity. 
 The Trustee shall not convert any currency in which the Debt Securities of such series are payable for the purposes of such sinking fund application unless a Company Request is made, and any such conversion agreed to
by the Trustee in response to such request shall be for the account and at the expense of the Company and shall not affect the Company’s obligation to pay the Holders in the currency to which such Holder is entitled. 
 On or before each sinking fund Redemption Date provided with respect to Debt Securities of any series, the Company shall pay to the Trustee in cash in
the currency described above a sum equal to all accrued interest, if any, to the date fixed for redemption on Debt Securities to be redeemed on such sinking fund Redemption Date pursuant to this Section 4.05. 
 ARTICLE 5. 
 PARTICULAR COVENANTS OF
THE COMPANY. 
 SECTION 5.01. Payment of Principal, Premium and Interest. The Company will duly and punctually pay or cause to be
paid (in the currency in which the Debt Securities of such series are payable) the principal of and premium, if any, and interest on each of the Debt Securities at the place (subject to Section 3.03), at the respective times and in the manner
provided in each series of Debt Securities and in this Indenture. 
 SECTION 5.02. Offices for Notices and Payments, etc. (a) So
long as the Debt Securities of any series remain Outstanding, the Company will maintain at the Place of Payment, an office or agency where the Debt Securities may be presented for payment, an office or agency where the Debt Securities may be
presented for registration of transfer and for exchange as provided in this Indenture, and an office or agency where notices and demands to or upon the Company in respect of the Debt Securities or of this Indenture may be served and shall give the
Trustee written notice thereof and any changes in the location thereof. In case the Company shall at any time fail to maintain any such office or agency, or shall fail to give notice to the Trustee of any change in the location thereof, presentation
and demand may be made and notice may be served in respect of the Debt Securities or of this Indenture at said office of the Trustee. 
  

 25 








 (b) In addition to the office or agency maintained by the Company pursuant to Section 5.02(a), the
Company may from time to time designate one or more other offices or agencies where the Debt Securities may be presented for payment and presented for registration of transfer and for exchange in the manner provided in this Indenture, and the
Company may from time to time rescind such designations, as the Company may deem desirable or expedient; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain
such office and agency at the Place of Payment, for the purposes abovementioned. The Company will give to the Trustee prompt written notice of (i) any such designation or rescission thereof, and (ii) the location of any such office or
agency outside the Place of Payment and of any change of location thereof. 
 SECTION 5.03. Appointments to Fill Vacancies in
Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 8.10, a Trustee, so that there shall at all times be a Trustee hereunder.

 SECTION 5.04. Provisions as to Paying Agent. (a) (1) Whenever the Company shall have one or more paying agents for any
series of Debt Securities other than the Trustee, it will, on or before each due date of the principal of (and premium, if any) or interest on any Debt Securities of such series, deposit with a paying agent a sum sufficient to pay such amount
becoming due, such sum to be held as provided by the Trust Indenture Act of 1939, and (unless such paying agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 (2) The Company will cause each paying agent other than the Trustee to execute and deliver to the Trustee an instrument in which such paying agent shall
agree with the Trustee, subject to the provisions of this Section, that such paying agent will: (i) comply with the provisions of the Trust Indenture Act of 1939 applicable to it as a paying agent and (ii) during the continuance of any
default by the Company (or any other obligor upon any series of Debt Securities) in the making of any payment in respect of the Debt Securities of such series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in
trust by such paying agent as such. 
 (b) If the Company shall act as its own paying agent, it will, on or prior to each due date of the
principal of and premium, if any, or interest on Debt Securities of any series, set aside, segregate and hold in trust for the benefit of the Holders of such Debt Securities a sum sufficient to pay such principal and premium, if any, or interest so
becoming due and will notify the Trustee of any failure to take such action and of any failure by the Company (or by any other obligor on such series of Debt Securities) to make any payment of the principal of and premium, if any, or interest on the
Debt Securities when the same shall become due and payable. 
 (c) Anything in this Section 5.04 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture with respect to any or all series of Debt Securities then Outstanding, or for any other reason, pay or cause to be paid to the Trustee all sums
held in trust by the Company, or any paying agent hereunder, as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained. 
  


 26 








 (d) Anything in this Section 5.04 to the contrary notwithstanding, the agreement to hold sums in
trust provided in this Section 5.04 is subject to Section 13.04. 
 SECTION 5.05. Certificate to Trustee. So long as the
Debt Securities of any series remain Outstanding, the Company will deliver to the Trustee on or before 120 days after the end of each fiscal year an Officers’ Certificate stating that in the course of the performance by the signers of their
duties as officers of the Company, they would normally have knowledge of any default by the Company in the performance or fulfillment or observance of any covenants or agreements contained herein during the preceding fiscal year, stating whether or
not they have knowledge of any such default and, if so, specifying each such default of which the signers have knowledge and the nature thereof. The Officers’ Certificate need not comply with Section 15.05. 
 SECTION 5.06. Waivers of Covenants. Anything in this Indenture to the contrary notwithstanding, the Company may fail or omit, in respect of any
series of Debt Securities, and in any particular instance, to comply with a covenant, agreement or condition contained in Sections 5.02, 5.04 (other than in 5.04(a)(1) and (2)) or 5.05, or with any additional covenant, agreement or condition
contained in a Board Resolution or Officers’ Certificate establishing such series of Debt Securities, any indenture supplemental hereto applicable to such series of any Debt Security of such series if the Company shall have obtained and filed
with the Trustee before or after the time for such compliance the consent in writing of the Holders of more than 50% in aggregate principal amount of the Debt Securities of the series affected by such waiver at the time Outstanding, either waiving
such compliance in such instance or generally waiving compliance with such covenant or condition, but no such waiver shall extend to or affect any obligation not expressly waived nor impair any right consequent thereon and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect. 
 ARTICLE 6. 
 HOLDERS’ LISTS AND REPORTS BY THE COMPANY 
 AND THE TRUSTEE. 
 SECTION 6.01.
Holders’ Lists. The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee, not more than 15 days after each Regular Record Date with respect to the Debt Securities of any series, and at such other
times as the Trustee may request in writing, within 30 days after receipt by the Company of any such request, a list in such form as the Trustee may reasonably require of the names and addresses of the Holders of Debt Securities of such series as of
a date not more than 15 days prior to the time such information is furnished; provided, however, that no such list with respect to any particular series of Debt Securities need be furnished at any such time if the Trustee
is in possession thereof by reason of its acting as the Debt Security Registrar for such series designated under Section 3.06 or otherwise. 
  

 27 








 SECTION 6.02. Preservation and Disclosure of Lists. (a) The Trustee shall preserve, in as
current a form as is reasonably practicable, all information as to the names and addresses of the Holders of Debt Securities contained in the most recent list furnished to it as provided in Section 6.01 or received by the Trustee in the
capacity of the Debt Security Registrar (if so acting) under Section 3.06. The Trustee may destroy any list furnished to it as provided in Section 6.01 upon receipt of a new list so furnished. 
 (b) The rights of Holders to communicate with other Holders with respect to their rights under this Indenture or under the Debt Securities of any series
or of all Debt Securities, and the corresponding rights and duties of the Trustee, shall be as provided by the Trust Indenture Act of 1939. 
 (c) Every Holder of Debt Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held accountable by reason of any disclosure
of information as to names and addresses of Holders made pursuant to the Trust Indenture Act of 1939. 
 SECTION 6.03. Reports by the
Company. The Company agrees to file with the Trustee and the Commission, and transmit to Holders, such information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act of 1939 at the

shall be filed with the Trustee within 15 days after the same is so required to be filed with the Commission.; provided further that any such information, documents or reports filed with the Commission pursuant to its Electronic Data
Gathering, Analysis and Retrieval (or EDGAR) system or any successor thereto shall be deemed to be filed with the Trustee. 
 SECTION 6.04.
Reports by the Trustee. (a) The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the Trust Indenture Act of 1939 at the times and in the manner
provided pursuant thereto. The interval between transmissions of reports to be transmitted at intervals shall be twelve months or such shorter time required by the Trust Indenture Act of 1939. If the Trust Indenture Act of 1939 does not specify the
date on which a report is due, the such report shall be due on July 15 of each year following the first issuance of Debt Securities. 
 (b) A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange upon which Debt Securities of any series are listed, with the Commission and with the Company. The Company
will notify the Trustee when the Debt Securities of any series are listed on any stock exchange and of any delisting thereof. 
 ARTICLE 7.

 ON EVENT OF DEFAULT. 
 SECTION 7.01. Events of Default. “Event of Default”, with
respect to any series of Debt Securities, wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to
any judgment, decree or order of any court or any order, rule

 (d) failure on the part of the Company duly to observe or perform any of the covenants, warranties or agreements on the part of the Company in respect of the Debt Securities of such series in this Indenture (other

failure and requiring the same to be remedied, shall have been given to the Company by the Trustee, by registered mail, or to the Company and the Trustee by the Holders of not less than 50% in aggregate principal amount of the Outstanding Debt
Securities of such series; 
 (e) a decree or order by a court having jurisdiction in the premises shall have been entered adjudging the
Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization of the Company under the Federal bankruptcy laws or any other similar applicable Federal or state law, and such decree or order shall have continued
undischarged and unstayed for a period of 60 days; or a decree or order of a court having jurisdiction in the premises for the appointment of a receiver or liquidator or trustee or assignee or other similar official in bankruptcy or insolvency of
the Company or of all or substantially all of its property, or for the winding up or liquidation of its affairs, shall have been entered, and such decree or order shall have continued undischarged and unstayed for a period of 60 days; 
 (f) the Company shall institute proceedings to be adjudicated a voluntary bankrupt, or shall consent to the filing of a bankruptcy proceeding against it,
or shall file a petition or answer or consent seeking an arrangement or a reorganization under the Federal bankruptcy laws or any other similar applicable Federal or state law, or shall consent to the filing of any such petition, or shall consent to
the appointment of a receiver or liquidator or trustee or assignee or other similar official in bankruptcy or insolvency of it or of all or substantially all of its property, or shall make an assignment for the benefit of creditors, or shall admit

 29 








 (g) any other Event of Default provided in the Board Resolution, Officers’ Certificate or the
supplemental indenture under which such series of Debt Securities is issued or in the form of Debt Security for such series; 
 then and in each and every
such case, so long as such Event of Default with respect to any series of Debt Securities for which there are Debt Securities Outstanding occurs and is continuing (other than an Event of Default specified in clause (e) or (f) of
Section 7.01) and shall not have been remedied or waived to the extent permitted by the terms of this Indenture, unless the principal of all of the Debt Securities of such series shall have already become due and payable, either the Trustee or
the Holders of not less than 50% in aggregate principal amount of the Outstanding Debt Securities of such series, by notice in writing to the Company (and to the Trustee if given by Holders), may declare the principal (or, if the Debt Securities of
that series are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified in the terms of that series) of all the Debt Securities of such series and the interest accrued thereon to be due and payable
immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Debt Securities of such series contained to the contrary notwithstanding. If an Event of Default
specified in clause (e) or (f) of Section 7.01 occurs and is continuing, then the principal amount of (or, if the Debt Securities of that series are Original Issue Discount Debt Securities, such portion of the principal amount as may
be specified in the terms thereof as due and payable upon acceleration) and any accrued and unpaid interest on that series shall immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. This
provision, however, is subject to the condition that if, at any time after the principal of the Debt Securities of such series shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall
have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay in the currency in which the Debt Securities of such series are payable all matured installments of interest upon
all of the Debt Securities and the principal of and premium, if any, on any and all Debt Securities of such series which shall have become due otherwise than by such declaration (with interest on overdue installments of interest to the extent that
payment of such interest is enforceable under applicable law and on such principal and premium, if any, at the rate borne by the Debt Securities of such series or as otherwise provided in the form of Debt Security for such series, to the date of
such payment or deposit) and the expenses of the Trustee (subject to Section 8.06), and any and all defaults under this Indenture, other than the nonpayment of principal of and accrued interest on Debt Securities of such series which shall have
become due by such declaration, shall have been cured or shall have been waived in accordance with Section 7.07 or provision deemed by the Trustee to be adequate shall have been made therefor — then and in every such case the Holders of at
least a majority in aggregate principal amount of the Debt Securities of such series then Outstanding, by written notice to the Company and to the Trustee, may rescind and annul such declaration and its consequences; but no such rescission and
annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon. 
 In case the Trustee or any
Holders shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission and annulment or for any other reason or shall have been determined adversely to the
Trustee, then and in every such case the Company, the Trustee and the Holders shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the Holders shall
continue as though no such proceeding had been taken.

 SECTION 7.02. Payment of Debt Securities Upon Default; Suit Therefor. The Company covenants that
(a) in case default shall be made in the payment of any installment of interest upon any Debt Security of any series as and when the same shall become due and payable, and such default shall have continued for a period of 30 days, or
(b) in case default shall be made in the payment of the principal of and premium, if any, on any Debt Security of any series as and when the same shall have become due and payable, whether at maturity of the Debt Security or upon redemption or
by declaration or otherwise, and such default shall have continued for a period of five days, or (c) in case default shall be made in the making or satisfaction of any sinking fund payment or analogous obligation with respect to the Debt
Securities of any series when the same becomes due by the terms of the Debt Securities of any series, and such default shall have continued for a period of 30 days—then, upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the Holders of any such series, the whole amount that then shall have become due and payable on any such Debt Securities for principal and premium, if any, or interest, or both, as the case may be, with interest upon the overdue principal
and premium, if any, and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate borne by the Debt Securities of such series or as otherwise provided in the form of Debt
Security of such series; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including a reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or
liabilities incurred and advances made by the Trustee, except compensation or advances arising, or expenses or liabilities incurred, as a result of the Trustee’s gross negligence or bad faith. 
 Until such demand is made by the Trustee, the Company may pay the principal of and premium, if any, and interest on the Debt Securities of any series to
the Persons entitled thereto, whether or not the principal of and premium, if any, and interest on the Debt Securities of such series are overdue. 
 In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for
the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor on such Debt Securities and
collect, in the manner provided by law out of the property of the Company or any other obligor on such Debt Securities wherever situated, the moneys adjudged or decreed to be payable. If any Event of Default with respect to any series of Debt
Securities occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Debt Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
  

 31 








 In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or
any other obligor on the Debt Securities of any series under the Federal bankruptcy laws or any other applicable law, or in case a receiver or trustee shall have been appointed for the property of the Company or such other obligor, or in the case of
any other similar judicial proceedings relative to the Company or other obligor upon the Debt Securities of any series, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the
Debt Securities of such series 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 pursuant to the provisions of this Section 7.02, shall be
entitled and empowered by intervention in such proceedings or otherwise, (a) to file and prove a claim or claims for the whole amount of principal and interest owing and unpaid in respect of the Debt Securities of such series, and, in case of
any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Holders of the Debt Securities of such series allowed in such judicial
proceedings relative to the Company or any other obligor on such Debt Securities, its or their creditors, or its or their property, (b) unless prohibited by applicable law and regulations, to vote on behalf of the Holders of any Debt Securities
of any series in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or person performing similar functions in comparable proceedings, and (c) to collect and
receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by
each of the Holders of the Debt Securities of such series to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to such Holders, to pay to the Trustee such amount as shall be
sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred and advances made by the Trustee except compensation or advances arising, or expenses or liabilities
incurred, as a result of the Trustee’s gross negligence or bad faith. 
 Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept, or adopt on behalf of any Holder any plan or reorganization, arrangement, adjustment or composition affecting the Debt Securities or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Holder (except, as aforesaid, for the election of a trustee in bankruptcy or other Person performing similar functions) in any such proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Debt Securities of any series, may be enforced by the Trustee
without the possession of any of such Debt Securities, or the production thereof on any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall be for the ratable benefit of the Holders of the Debt Securities of such series in respect of which such judgment has been recovered. 
 In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee
shall be a party), the Trustee shall be held to represent all the Holders of the Debt Securities in respect to which such action was taken, and it shall not be necessary to make any Holders of such Debt Securities parties to any such proceedings.

  

 32 








 SECTION 7.03. Application of Moneys Collected by Trustee. Any moneys collected by the Trustee
pursuant to Section 7.02 and any other money or property distributed in respect of the Company’s obligations under this Indenture after an Event of Default shall be applied in the order following, at the date or dates fixed by the Trustee
for the distribution of such moneys, upon presentation of the Debt Securities of such series, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 FIRST: To the payment of costs and expenses of collection and reasonable compensation to the Trustee, its agents, attorneys and counsel, and of all other
expenses and liabilities incurred, and all advances made, by the Trustee except compensation or advances arising, or expenses or liabilities incurred, as a result of its gross negligence or bad faith, and any other amounts owing the Trustee under
Section 8.06; 
 SECOND: To the payment of the amounts then due and unpaid to the holders of Senior Indebtedness, to the extent required
by Article Sixteen; 
 THIRD: In case the principal of the Debt Securities of such series shall not have become due and be unpaid, to the
payment of interest on such Debt Securities, in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate
borne by such Debt Securities, such payments to be made ratable to the Persons entitled thereto; 
 FOURTH: In case the principal of the Debt
Securities of such series shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon such Debt Securities for principal and premium, if any, and interest, with interest on the overdue principal
and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by such Debt Securities; and in case such moneys shall be insufficient to pay in full the whole
amounts so due and unpaid upon such Debt Securities, then, to the payment of such principal and premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium,
if any, or of any installment of interest over any other installment of interest, or of any Debt Security of such series over any other such Debt Security, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid
interest; 
 FIFTH: To the payment of any surplus then remaining to the Company, its successors or assigns, or to whomsoever may be lawfully
entitled to receive the same. 
 SECTION 7.04. Proceedings by Holders. No Holder of any Debt Security of any series shall have any
right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law or in bankruptcy or otherwise upon or under or with respect to this Indenture or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of not less than 50% in
aggregate principal amount of the Debt Securities of such series 

  

 33 








 
then Outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall
have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity,
shall have neglected or refused to institute any such action, suit or proceeding (and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 7.07), it being understood and intended, and
being expressly covenanted by the taker and Holder of every Debt Security of every series with every other taker and Holder and the Trustee, that no one or more Holders of Debt Securities shall have any right in any manner whatever by virtue of or
by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder of such Debt Securities, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under
this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Debt Securities. 
 SECTION 7.05. Proceedings by Trustee. In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders vested in it by this Indenture by such
appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 
 SECTION 7.06. Remedies Cumulative and Continuing. All powers and remedies given by this Article Seven to the Trustee or to the Holders shall, to
the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any default occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of Section 7.04, every power and remedy given by this Article Seven or by law to the Trustee or to the Holders may be exercised
from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 
 SECTION 7.07. Direction of Proceedings
and Waiver of Defaults by Majority of Holders. The Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of any series shall have the right to direct the time, method, and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to the Debt Securities by this Indenture; provided, however, that (subject to the provisions of Section 8.01) the Trustee shall have the
right to decline to follow any such direction if the Trustee shall determine upon advice of counsel that the action or proceeding so directed may not lawfully be taken or would be materially and unjustly prejudicial to the rights of Holders not
joining in such direction or if the Trustee in good faith by its board of directors or trustees, executive committee, or a trust committee of directors or trustees and/or Responsible Officers shall determine that the action or proceeding so directed


  

 34 








 
would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forbearances specified in or pursuant
to such direction would be unduly prejudicial to the interests of Holders of the Debt Securities of all series not joining in the giving of said direction, it being understood that (subject to Section 8.01) the Trustee shall have no duty to
ascertain whether or not such actions or forbearances are duly prejudicial to such Holders. The Trustee may take any other action deemed proper by the Trustee not inconsistent with such direction. Subject to Section 7.01, the Holders of a
majority in aggregate principal amount of the Outstanding Debt Securities of any series may on behalf of the Holders of all the Debt Securities of such series waive any past default or Event of Default hereunder and its consequences except a default
in the payment of principal of or premium, if any, or interest on such Debt Securities, or a default in the making of any sinking fund payment with respect to such Debt Securities. Upon any such waiver the Company, the Trustee and the Holders of
such Debt Securities shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default
or Event of Default shall have been waived as permitted by this Section 7.07, said default or Event of Default shall for all purposes of the Debt Securities and this Indenture be deemed to have been cured and to be not continuing. 

This Section 7.07 shall be in lieu of Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act of 1939 and such Sections 316(a)(1)(A)
and Section 316(a)(1)(B) are hereby expressly excluded from this Indenture, as permitted by the Trust Indenture Act of 1939. 
 SECTION
7.08. Notice of Defaults. Within 90 days after the occurrence of any default hereunder with respect to the Debt Securities of any series, the Trustee shall transmit first-class by mail, postage prepaid, to all Holders of Debt Securities of
such series, as their names and addresses appear in the Debt Security Register, notice of such default hereunder known to the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in
the payment of the principal of (or premium, if any) or interest on any Debt Security of such series or in the payment of any sinking fund installment with respect to Debt Securities of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of Debt
Securities of such series; and provided, further, that in the case of any default of the character specified in Section 7.01(d) with respect to Debt Securities of such series, no such notice to Holders shall be given until at least 60 days
after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Debt Securities of such series.

 SECTION 7.09. Undertaking to Pay Costs. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the
manner and to the extent provided in the Trust Indenture Act of 1939; provided that neither this Section nor the Trust Indenture Act of 1939 shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any
suit instituted by the Company or the Trustee, and any provision of the Trust Indenture Act of 1939 to such effect is hereby expressly excluded from this Indenture, as permitted by the Trust Indenture Act of 1939. 
  

 35 








 SECTION 7.10. Unconditional Right of Holders to Receive Principal, Premium and Interest.
Notwithstanding any other provision in this Indenture, the Holder of any Debt Security shall have the rights, which are absolute and unconditional, to receive payment of the principal of, premium, if any, and (subject to Section 3.08) interest
on such Debt Security on the respective Stated Maturities expressed in such Debt Security (or in the case of redemption or repayment, on the date for redemption or repayment, as the case may be) and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such Holder. 
 ARTICLE 8. 
 CONCERNING THE TRUSTEE. 
 SECTION 8.01.
Duties and Responsibilities of Trustee.

such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee. 
 (b) In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture,
and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 
 (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this Subsection (c) shall not be construed to limit the effect of Subsections (a) or (d) of this Section 8.01;

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

place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series. 
 (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably
assured to it. 
  

 36 








 (e) Whether or not therein expressly so provided, every provision of this Indenture relating to the
conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 8.01. 
 SECTION 8.02. Reliance on Documents, Opinions, etc.. Subject to the provisions of Section 8.01, 
 (a) the Trustee may
rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note or other paper document believed by it to be genuine and
to have been signed or presented by the proper party or parties; 
 (b) any request, direction, order or demand of the Company mentioned

by the Holders of not less than a majority in principal amount of such Debt Securities then Outstanding; provided, however, that the reasonable expenses of every such investigation shall be paid by the Company or, if paid by the
Trustee, shall be repaid by the Company upon demand; and provided, further, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to
so proceeding; 
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or
through agents or attorneys, and the Trustee shall not be liable or responsible for any misconduct, bad faith or negligence on the part of any agent or attorney appointed with due care by it hereunder; 
  

 37 








 (h) the Trustee shall not be deemed to have notice or be charged with knowledge of any default or Event

this Indenture; 
 (i) the rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and 
 (j) the permissive rights of the Trustee enumerated herein shall not be construed as duties. 
 SECTION 8.03. No Responsibility for Recitals, etc. The recitals contained herein and in the Debt Securities (except in the Trustee’s
certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of
the Debt Securities of any series. The Trustee represents that it is duly authorized to execute and deliver this Indenture. Neither the Trustee nor the Authenticating Agent shall be accountable for the use or application by the Company or any Debt
Securities or the proceeds of any Debt Securities authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 
 SECTION 8.04. Trustee and Agents May Own Debt Securities. The Trustee, any paying agent, or any agent of the Trustee or the Company under this Indenture, in its individual or any other capacity, may become the owner or pledgee of
Debt Securities of any series with the same rights it would have if it were not Trustee or such agent and, subject to Sections 8.08 and 8.13, if operative, may otherwise deal with the Company and receive, collect, hold, and retain collections from
the Company with the same rights it would have if it were not the Trustee or such agent. 
 SECTION 8.05. Moneys to be Held in Trust.
Subject to the provisions of Section 13.04, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except
to the extent required by law. Neither the Trustee nor any paying agent shall be under any liability for interest on, or to invest, any moneys received by it hereunder except such as it may agree with the Company to pay thereon. So long as no Event
of Default with respect to the Debt Securities of any series shall have occurred and be continuing, all interest allowed on any such moneys shall be paid from time to time upon the receipt of a Company Order. 
 SECTION 8.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and the Company will pay or reimburse the 

  

 38 








 
Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of
this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and all persons not regularly in its employ and any amounts paid by the Trustee to any Authenticating Agent pursuant to Section 8.14) except
any such expense, disbursement or advance as may arise from its gross negligence or bad faith. The Company also covenants to indemnify the Trustee for, and to hold it harmless against, any loss, damage, claims, liability or expense incurred without
gross negligence or bad faith on the part of the Trustee and arising out of or in connection with this Indenture, including the acceptance or administration of this trust, or the performance of its duties hereunder, including the current payment of
all costs and expenses of defending itself against any claim of liability in the premises. The obligations of the Company under this Section 8.06 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior to that of the Debt Securities upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the benefit of the Holders of particular Debt Securities. In addition to, but without prejudice to its other rights under this indenture, when the Trustee incurs expenses or renders services in connection with an Event of
Default specified in Section 7.01(e) or Section 7.01(f), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any
applicable Federal or state bankruptcy, insolvency or other similar law. 
 “Trustee” for purposes of this Section shall include
any predecessor Trustee; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 
 The provisions of this Section shall survive the termination of this Indenture, the satisfaction and discharge of this Indenture and the resignation or
removal of the Trustee. 
 SECTION 8.07. Officers’ Certificate as Evidence. Subject to the provisions of Section 8.01,
whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in
respect thereof be herein specifically prescribed) may, in the absence of gross negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate conforming to the requirements
of this Indenture delivered to the Trustee, and such Certificate, in the absence of gross negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this
Indenture upon the faith thereof. 
 SECTION 8.08. Conflicting Interest of Trustee. If the Trustee has or shall acquire any
conflicting interest within the meaning of the Trust Indenture Act of 1939, the Trustee shall either eliminate such conflicting interest or resign in the manner provided by, and subject to the provisions of, the Trust Indenture Act of 1939 and this
Indenture. 
 SECTION 8.09. Eligibility of Trustee. There shall at all times be a Trustee with respect to each series of Debt
Securities hereunder which shall be a Person organized and doing business under the laws of the United States or any state or territory thereof or of the District of 

  

 39 








 
Columbia authorized under such laws to exercise trust powers, having a combined capital and surplus of at least $50,000,000, subject to supervision or
examination by Federal, state, territorial, or District of Columbia authority and willing to act as Trustee hereunder. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 8.09, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so
published. In case at any time the Trustee with respect to any series of Debt Securities shall cease to be eligible in accordance with the provisions of this Section 8.09, such Trustee shall resign immediately in the manner and with the effect
specified in Section 8.10. 
 SECTION 8.10. Resignation or Removal of Trustee. (a) The Trustee may at any time resign with
respect to any series of Debt Securities by giving written notice by first class mail of such resignation to the Company and to the Holders of such series of Debt Securities at their addresses as they shall appear on the Debt Security Register. Upon
receiving such notice of resignation, the Company shall promptly appoint a successor trustee with respect to such series by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee with respect to such series shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation
to the Holders, the resigning Trustee may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder of such series of Debt Securities who has been a bona fide Holder of a
Debt Security or Debt Securities of such series for at least six months may, subject to the provisions of Section 7.09, on behalf of such Holder and all others similarly situated, petition any such court for the appointment of a successor
trustee with respect to such series. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint such successor trustee. 
 (b) In case at any time any of the following shall occur: 
 (1) the Trustee shall fail to comply with the
provisions of Section 8.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Debt Security or Debt Securities of such series for at least six months, unless the Trustee’s duty to resign is
stayed in accordance with the provisions of Section 310(b) of the Trust Indenture Act of 1939, 
 (2) the Trustee shall cease to be
eligible in accordance with the provisions of Section 8.09 and shall fail to resign after written request therefor by the Company or by any such Holder of a note of such series, or 
 (3) the Trustee shall become incapable of acting with respect to any series of Debt Securities, 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; 
  

 40 








 then, in any such case, the Company may remove the Trustee with respect to such series and appoint a successor trustee
for such series by Company Order, one copy of which Company Order shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.09, any Holder who has been a bona fide Holder of a
Debt Security or Debt Securities of such series for at least six months may, on behalf of such Holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor
trustee with respect to such series. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove such Trustee and appoint such successor trustee. 
 (c) The Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of any series may at any time remove the Trustee with
respect to such series by delivering to the Trustee so removed, to the successor trustee so appointed and to the Company the evidence provided for in Section 9.01 of the action in that regard taken by the Holders, and nominate a successor
Trustee which shall be deemed appointed as successor Trustee unless within ten days after such nomination the Company objects thereto, in which case the Trustee so removed or any Holder of a Debt Security or Debt Securities of such series, upon the
terms and conditions and otherwise as in subsection (a) of this Section 8.10 provided, may petition any court of competent jurisdiction for an appointment of a successor Trustee with respect to such series. 
 (d) Any resignation or removal of the Trustee with respect to all or any series of Debt Securities and any appointment of a successor Trustee pursuant to
any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor Trustee as provided in Section 8.11. 
 SECTION 8.11. Acceptance by Successor Trustee. Any successor Trustee appointed as provided in Section 8.10 shall execute, acknowledge and deliver to the Company and to its predecessor Trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee shall become effective with respect to all or any series as to which it is resigning as Trustee, and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder with respect to all or any such series, with like effect as if originally named as Trustee herein with respect to
all or any such series; nevertheless, on the written request of the Company or of the successor Trustee, the Trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06, execute and deliver
an instrument transferring to such successor Trustee all the rights and powers of the Trustee with respect to all or any such series so ceasing to act. Upon request of any such successor Trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a lien upon all property or funds held or collected by such Trustee with
respect to all or any series as to which it is resigning as Trustee, to secure any amounts and shall be entitled to any indemnities then due it pursuant to the provisions of Section 8.06. 
 No successor Trustee shall accept appointment as provided in this Section 8.11 unless at the time of such acceptance such successor Trustee shall be
qualified under the provisions of Section 8.08 and eligible under the provisions of Section 8.09. 
  

 41 








 Upon acceptance of appointment by a successor Trustee with respect to all or any series of Debt
Securities as provided in this Section 8.11, the Company shall mail notice of the succession of such Trustee hereunder to the Holders of Debt Securities of such series at their addresses as they shall appear on the Debt Security Register. If
the Company fails to mail such notice within ten days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the Company. 
 In case the appointment hereunder of a successor Trustee with respect to the Debt Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Debt Securities of any applicable series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Debt Securities of any series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and shall add to
or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such Trustee shall be Trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee. 
 SECTION 8.12. Succession by Merger, etc. Subject to Sections 8.08 and 8.09, any Person into which the Trustee may be merged or converted or with
which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all 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 at the time any successor to the Trustee shall succeed to the trusts created by this Indenture any of the Debt Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor Trustee, and deliver such Debt Securities so authenticated; and in case at that time any of the Debt Securities shall not have been authenticated, any successor to the Trustee may authenticate such Debt
Securities in the name of such successor Trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Debt Securities or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 8.13. Limitation on Rights of Trustee as a Creditor. If and when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Debt Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act of 1939 regarding the collection of claims against the Company (or any such other obligor). 
 SECTION 8.14. Authenticating Agents. There may be an Authenticating Agent or Authenticating Agents appointed by the Trustee from time to time with
power to act on its behalf and subject to its direction in the authentication and delivery of any series of Debt Securities issued upon original issuance, exchange, transfer or redemption thereof as fully to all intents and purposes as though such
Authenticating Agent (or Authenticating Agents) had been expressly authorized to authenticate and deliver such Debt Securities, and Debt Securities so authenticated 

  

 42 








 
shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as though authenticated by the Trustee hereunder. For
all purposes of this Indenture, the authentication and delivery of Debt Securities by any Authenticating Agent pursuant to this Section 8.14 shall be deemed to be the authentication and delivery of such Debt Securities “by the
Trustee”, and whenever this Indenture provides that “the Trustee shall authenticate and deliver” Debt Securities or that Debt Securities “shall have been authenticated and delivered by the Trustee”, such authentication and
delivery by any Authenticating Agent shall be deemed to be authentication and delivery by the Trustee. Any such Authenticating Agent shall at all times be a Person organized and doing business under the laws of the United States of America or of any
state or territory thereof or the District of Columbia, with a combined capital and surplus of at least $50,000,000 and authorized under such laws to act as an authenticating agent, duly registered to act as such, if and to the extent required by
applicable law and subject to supervision or examination by Federal or state authority. If such Person publishes reports of its condition at least annually pursuant to law or the requirements of such authority, then for the purposes of this
Section 8.14 the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 8.14, or to be duly registered if and to the extent required by applicable law and regulations, it shall resign immediately in the manner and with the effect herein specified in this
Section 8.14. 
 Whenever reference is made in this Indenture to the authentication and delivery of Debt Securities of any series 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 its Authenticating Agent appointed with respect to the Debt Securities of such series and
a certificate of authentication executed on behalf of the Trustee by its Authenticating Agent appointed with respect to the Debt Securities of such series. 
 Any Person into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any Person succeeding to the authenticating agency business of any Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, if such successor Person is otherwise eligible under this Section 8.14,
without the execution or filing of any paper or any further act on the part of the parties hereto or such Authenticating Agent or such successor Person. 
 In case at the time such successor to any such agency shall succeed to such agency any of the Debt Securities shall have been authenticated but not delivered, any such successor to such Authenticating Agent may adopt
the certificate of authentication of any predecessor Authenticating Agent and deliver such Debt Securities so authenticated; and in case at that time any of the Debt Securities shall not have been authenticated, any successor to any Authenticating
Agent may authenticate such Debt Securities either in the name of any predecessor hereunder or in the name of the successor Authenticating Agent; and in all cases such certificate shall have the full force which it has anywhere in the Debt
Securities or in this Indenture provided that the certificate of the predecessor Authenticating Agent shall have had such force; provided, however, that the right to adopt the certificate of authentication of any predecessor Authenticating
Agent or to authenticate Debt Securities in the name of any predecessor Authenticating Agent shall apply only to its successor or successors by merger, conversion or consolidation. 
  

 43 








 Any Authenticating Agent may at any time resign as Authenticating Agent with respect to any series of
Debt Securities by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any Authenticating Agent with respect to any series of Debt Securities by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time Authenticating Agent shall cease to be eligible under this Section 8.14, the Trustee
may, and shall, upon request of the Company, promptly use its best efforts to appoint a successor Authenticating Agent. 
 Upon the
appointment, at any time after the original issuance of any of the Debt Securities, of any successor, additional or new Authenticating Agent, the Trustee shall give written notice of such appointment to the Company and shall at the expense of the
Company mail notice of such appointment to all Holders of Debt Securities of such series as the names and addresses of such Holders appear on the Debt Security Register. 
 Any successor Authenticating Agent with respect to any series of Debt Securities upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder,
with like effect as though originally named as an Authenticating Agent herein with respect to such series. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 8.14 and duly registered if and
to the extent required under applicable law and regulations. 
 Any Authenticating Agent by the acceptance of its appointment with respect to
any series of Debt Securities shall be deemed to have agreed with the Trustee that: (a) it will perform and carry out the duties of an Authenticating Agent as herein set forth with respect to such series, including the duties to authenticate
and deliver Debt Securities when presented to it in connection with exchanges, registrations of transfer or redemptions thereof; (b) it will keep and maintain, and furnish to the Trustee from time to time as requested by the Trustee appropriate
records of all transactions carried out by it as Authenticating Agent and will furnish the Trustee such other information and reports as the Trustee may reasonably require; (c) it is eligible for appointment as Authenticating Agent under this
Section 8.14 and will notify the Trustee promptly if it shall cease to be so qualified; and (d) it will indemnify the Trustee against any loss, liability or expense incurred by the Trustee and will defend any claim asserted against the
Trustee by reason of any acts or failures to act of the Authenticating Agent with respect to such series but it shall have no liability for any action taken by it at the specific written direction of the Trustee. 
 The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation and expenses for its services, and the Trustee shall
have no liability for such payments. 
 The provisions of Sections 8.02(a), (b), (c), (e) and (f), 8.03, 8.04, 8.06 (insofar as it
pertains to indemnification), 9.01, 9.02 and 9.03 shall bind and inure to the benefit of each Authenticating Agent to the same extent that they bind and inure to the benefit of the Trustee. 
  

 44 








 If an appointment with respect to one or more series is made pursuant to this Section 8.14, the Debt
Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form: 
 This is one of the Debt Securities of the series designated herein issued under the within-mentioned Indenture.

 SECTION 8.15. Preferential Collection of Claims Against the Company. 
 If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Debt Securities), the Trustee shall be subject to the provisions of
the Trust Indenture Act of 1939 regarding the collection of claims against the Company (or any such other obligor). 
 SECTION 8.16.
Trustee’s Application for Instructions from the Company. 
 Any application by the Trustee for written instructions from the Company may, at the
option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be
liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any
officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have
received written instructions in response to such application specifying the action to be taken or omitted. 
 ARTICLE 9. 

CONCERNING THE HOLDERS. 
 SECTION
9.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Debt Securities of any series may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other action) the fact that at the time of taking any such action the Holders of such specified percentage of such series have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by Holders of such series in person or by agent or proxy appointed in writing, or (b) by the record of 

  

 45 








 
the Holders of such series voting in favor thereof at any meeting of such Holders duly called and held in accordance with the provisions of Article Ten, or
(c) by a combination of such instrument or instruments and any such record of such a meeting of Holders of such series. 
 SECTION 9.02.
Proof of Execution by Holders. Subject to the provisions of Sections 8.01, 8.02 and 10.05, proof of the execution of any instrument by a Holder or such Holder’s agent or proxy shall be sufficient if made in accordance with such
reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The ownership of Debt Securities shall be provided by the Debt Security Register or by a certificate of the Debt Security
Registrar with respect to a series of Debt Securities. 
 The record of any Holders’ meeting shall be proved in the manner provided in
Section 10.06. 
 SECTION 9.03. Who Are Deemed Absolute Owners. The Company, the Trustee with respect to a series of Debt
Securities, and any agent of the Trustee or the Company under this Indenture may deem the Person in whose name such Debt Security shall be registered upon the Debt Security Register to be, and may treat such Person as, the absolute owner of such
Debt Security (whether or not such Debt Security shall be overdue and notwithstanding any notation of ownership or other writing thereon made by anyone other than the Company, the Trustee or any such agent) for the purpose of receiving payment of or
on account of the principal of and premium, if any, and interest on such Debt Security and for all other purposes; and neither the Company nor the Trustee nor any such agent shall be affected by any notice to the contrary. 
 SECTION 9.04. Company-Owned Debt Securities Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Debt
Securities of any series have concurred in any direction or consent under this Indenture, Debt Securities of such series which are owned by the Company or any other obligor upon such Debt Securities or any Affiliate of the Company or such other
obligor (except in the case in which the Company or such other obligor or affiliate owns all Debt Securities Outstanding under the Indenture, or all Outstanding Debt Securities of each such series, as the case may be, without regard to this proviso)
shall be disregarded and deemed not to be Outstanding for the purpose of any such determinations; provided, however, that for the purposes of determining whether the Trustee shall be protected in relying on any such direction or
consent only such Debt Securities which a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Debt Securities so owned which have been pledged in good faith may be regarded as Outstanding notwithstanding this
Section 9.04 if the pledgee shall establish to the satisfaction of the Trustee the right of the pledgee to vote such Debt Securities and that the pledgee is not a Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any such other obligor. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Debt Securities of a series, if any, known
by the Company to be owned or held by or for the account of the Company or any other obligor on such Debt Securities or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or
any other obligor on such Debt Securities; and, subject to the provisions of Section 8.01, the Trustee shall be entitled to accept such Officers’ Certificates as conclusive evidence of the facts therein set forth and of the fact that all
such Debt Securities not listed therein are Outstanding for the purpose of any such determination. 
  

 46 








 SECTION 9.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after)
the evidencing to the Trustee, as provided in Section 9.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this Indenture in connection with such
action, any Holder of a Debt Security which is shown by the evidence to be included in the Debt Securities the Holders of which have consented to or are bound by consents to such action, may, by filing written notice with the Trustee at the
Corporate Trust Office and upon proof of holding as provided in Section 9.02, revoke such action so far as concerns such Debt Security. Except as aforesaid any such action taken by the Holder of any Debt Security shall be conclusive and binding
upon such Holder and upon all future Holders and owners of such Debt Security and of any Debt Security issued on transfer thereof or in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon any
such Debt Security. Any action taken by the Holders of the percentage in aggregate principal amount of the Debt Securities specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the
Holders of all of the Debt Securities affected by such action. 
 ARTICLE 10.

Securities of all or any series to take any action specified in Section 10.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of the Holders of Debt Securities of all or any series, setting
forth the time and place of such meeting and in general terms the action proposed to be taken at such meeting, shall be mailed by the Trustee to Holders of Debt Securities of each series that may be affected by the action proposed to be taken at
such meeting at their addresses as they shall appear on the Debt Security Register. Such notice shall be mailed not less than 20 nor more than 90 days prior to the date fixed for the meeting. 
  

 47 








 SECTION 10.03. Call of Meetings by Company or Holders. In case at any time the Company, pursuant
to a resolution by the Board of Directors, or the Holders of at least 25% in aggregate principal amount of the Debt Securities then Outstanding of each series that may be affected by the action proposed to be taken shall have requested the Trustee
to call a meeting of such Holders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within 20 days after receipt of such request,
then the Company or such Holders may determine the time and place for such meeting and may call such meeting to take any action authorized in Section 10.01, by mailing notice thereof as provided in Section 10.02.

of one or more Debt Securities of a series affected by the action proposed to be taken or (b) be a Person appointed by an instrument in writing as proxy by a Holder of one or more such Debt Securities. The rights of Holders of Debt Securities
to have their votes counted shall be subject to the provision in the definition of “Outstanding” in Section 1.01. The only Persons who shall be entitled to be present or to speak at any meeting of Holders of Debt Securities 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 10.05. Regulations. 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 Debt Securities, in
regard to proof of the holding of Debt Securities 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 think fit. Except as otherwise permitted or required by any such regulation, the holding of Debt Securities shall be proved in the manner specified in Section 9.02 and the
appointment of any proxy shall be proved in the manner specified in said Section 9.02 or by having the signature of the Person executing the proxy witnessed or guaranteed by any bank, broker or trust company. 
 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 Debt Securities as provided in Section 10.03, in which case the Company or the Holders of Debt Securities calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a
secretary of the meeting shall be elected by vote of the Holders of a majority in aggregate principal amount of the Debt Securities represented at the meeting and entitled to vote. 
 Subject to the provisions of Section 9.04, at any meeting each Holder of a Debt Security of a series entitled to vote at such meeting or proxy shall
be entitled to one vote for each $1,000 principal amount of Debt Securities of such series held or represented by such Holder; provided, however, that no vote shall be cast or counted at any meeting in respect of any Debt 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 Debt Securities of such series or proxy therefor. Any meeting of Holders of Debt Securities duly called pursuant to the provisions of Section 10.02 or 10.03 may be adjourned from time to time and the meeting may be held as so
adjourned without further notice. 
 At any meeting of Holders of Debt Securities, the presence of Persons holding or representing Debt
Securities in an aggregate principal amount sufficient to take action upon the business for the transaction of which such meeting was called shall be necessary to constitute a quorum; but, if less than quorum be present, the Persons holding or
representing a majority of the Debt Securities represented at the meeting may adjourn such meeting with the same effect, for all intents and purposes, as though a quorum had been present. 
 SECTION 10.06. Voting. The vote upon any resolution submitted to any meeting of Holders of Debt Securities shall be by written ballots on which
shall be subscribed the signatures of the Holders of Debt Securities entitled to vote at such meeting or of their representatives by proxy, and the letter or letters, serial number or numbers or other distinguishing marks of the Debt Securities held
or represented by each such Holder. 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 duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders of Debt Securities 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
mailed as provided in Section 10.02. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other 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. 
 SECTION 10.07. No Delay of Rights by Meeting. Nothing in this Article Ten
contained shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders of Debt Securities of any or all series or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay
in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders of Debt Securities under any of the provisions of this Indenture or of the Debt Securities. 
 ARTICLE 11. 
 SUPPLEMENTAL INDENTURES. 
 SECTION 11.01. Supplemental Indentures without Consent of Holders. The Company, when authorized by a Board Resolution, and the Trustee may from

purposes: 
 (a) to evidence the succession of another Person to the Company, or successive successions, and the assumption by the successor
Person of the covenants, agreements and obligations of the Company pursuant to Articles Five and Twelve hereof;

its creditors other than holders of such Senior Indebtedness, and the Holders of the Debt Securities, no such payment or distribution made to the holders of such Senior Indebtedness by virtue of this Article which otherwise would have been made to
the Holders of the Debt Securities shall be deemed to be a payment by the Company on account of such Senior Indebtedness, it being understood that the provisions of this Article are and are intended solely for the purpose of defining the relative
rights of the Holders of the Debt Securities, on the one hand, and the holders of Senior Indebtedness. 
 SECTION 16.03. Obligation of the
Company Unconditional. Nothing contained in this Article or elsewhere in this Indenture or in the Debt Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Indebtedness, and the

trustee in bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee or agent or other Person making any payment or distribution, delivered to the Trustee or to the Holders of the Debt Securities, for the purpose of

other facts pertinent thereto or to this Article. 
 SECTION 16.04. Payments on Debt Securities Permitted. Nothing contained in this

of the Debt Securities in accordance with the provisions hereof and thereof, except as otherwise provided in this Article. 
 SECTION 16.05.
Effectuation of Subordination by Trustee. Each Holder of Debt Securities, by such Holder’s acceptance thereof, authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article and appoints the Trustee such Holder’s attorney-in-fact for any and all such purposes. 
 SECTION 16.06. Trustee Has No Fiduciary Duty to Holders of Senior Indebtedness; Knowledge of Trustee. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Indenture, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness, and shall not be liable to any such holders if it shall pay over or deliver to the Holders or the Company or any other Person, money or assets to which any holders of Senior Indebtedness shall be
entitled by virtue of this Article or otherwise. Notwithstanding the provisions of this Article or any other provisions of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making
of any payment of moneys to or by the Trustee in respect of the Debt Securities of any series, or the taking of any other action by the Trustee, unless and until a Responsible Officer of the Trustee shall have received at the Corporate Trust Office
of the Trustee written notice thereof from the Company, any Holder of Debt Securities, any paying or conversion agent of the Company or the holder or representative of any class of Senior Indebtedness; and before the receipt of any such written
notice, the Trustee shall be 

  

 62 








 
entitled in all respects to assume that no such facts exist; provided that if the Trustee shall not have received the notice provided for in this
Section at least three Business Days prior to the date upon which, by the terms hereof, any money may become payable for any purpose (including the payment of the principal of or interest on, or additional amounts owing in respect of, any Debt
Security) then, anything herein contained to the contrary notwithstanding, the Trustee shall have all power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it during or after such three Business Day period. 
 SECTION 16.07. Trustee May Hold
Senior Indebtedness. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Indebtedness at the time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in Section 313 of the TIA or elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder. 
 Nothing in this Article shall apply to the claims of, or payments to, the Trustee under or pursuant to Sections 7.03 and 8.06. 
 SECTION 16.08. Rights of Holders of Senior Indebtedness Not Impaired. No right of any present or future holder of any Senior Indebtedness to enforce the subordination herein shall at any time or in any way be
prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.
