 SECTION
104. Acts of Holders; Record Dates. 
 Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate
principal amount of the Securities of any or all series may take action (including the making of any demand or request, the giving of any direction, 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 have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, (b) by
the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with procedures approved by the Trustee, (c) by a combination of such instrument or instruments and any such record of such a meeting
of Holders or (d) in the case of Securities evidenced by a Global Security, by any electronic transmission or other message, whether or not in written format, that complies with the Depositary’s applicable procedures. Such evidence (and
the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the relevant Holders. Proof of execution of any such instrument or of a writing appointing any such agent or proxy shall be sufficient for
any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that
the Trustee deems sufficient. 
 The ownership of Securities shall be proved by the Security Register. 
 Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon,
whether or not notation of such action is made upon such Security. 
 The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken
by Holders of Securities of such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to
in the next paragraph. If any record date is set pursuant to this paragraph, the Holders 

  

 8 

 
of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not
such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 
 The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any
declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of
such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether
or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of
such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 
 With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration
Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each
Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party
hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 
  

 9 

 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to
any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal
amount. 
 SECTION 105. Notices, Etc., to Trustee and Company. 
 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: 
 (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in
writing in the English language to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Department; or 
 (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing in the English language and mailed, first-class postage prepaid, addressed to it at
the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company. 
 SECTION 106. Notice to Holders; Waiver. 
 Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than
the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be
impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 SECTION 107. Conflict with Trust Indenture Act. 
 If any
provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies
or excludes any 

  

 10 

 
provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or
to be excluded, as the case may be. 
 SECTION 108. Effect of Headings and Table of Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
 SECTION 109. Successors and Assigns. 
 All covenants and
agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. 
 SECTION 110. Separability Clause.

 In case any provision in this Indenture or the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforce
ability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 111. Benefits of Indenture. 
 Nothing in this Indenture or the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder
and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 112. Governing Law. 
 This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York. 
 SECTION 113. Legal Holidays. 
 In any case where any Interest
Payment Date, Redemption Date, purchase date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any
Security which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding
Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date or purchase date, or at the Stated Maturity.

the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

this Security at the times, place and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to
certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and
any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities of this series are issuable only in registered form without coupons in denominations of
$             and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’ Certificate referred to above or in any such indenture
supplemental hereto. 
 If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an
appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series.

 SECTION 302. Denominations. 
 The Securities
of each series shall be issuable only in registered form without coupons and only in such denominations as shall be specified as contemplated by Section 301. In the absence of any such specified denomination with respect to the Securities of
any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof. 
 SECTION 303. Execution,
Authentication, Delivery and Dating. 
 The Securities shall be executed on behalf of the Company by its Chairman of the Board of Directors,
its Vice Chairman of the Board of Directors, its President or one of its Vice Presidents. If its corporate seal is reproduced thereon, then it shall be attested by its Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile. 
 Securities bearing the manual or facsimile signatures of individuals who were at
any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the
date of such Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver
Securities of any series executed by the Company and, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this
Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating, 
 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 201, that such
form has been established in conformity with the provisions of this Indenture; 
 (2) if the terms of such Securities have
been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 
  

 22 

 (3) that such Securities, when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights,
duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 
 Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior
to the authentication upon original issuance of the first Security of such series to be issued. 
 Each Security shall be dated the date of
its authentication. 
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence,
that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this
Indenture. 
 SECTION 304. Temporary Securities. 
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine,
as evidenced by their execution of such Securities. 
 If temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender
of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any 

  

 23 

 
series, the Company shall execute, and the Trustee shall authenticate and deliver, in exchange therefor one or more definitive Securities of the same series,
of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such
series and tenor. 
 SECTION 305. Registration, Registration of Transfer and Exchange. 
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office
or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
 Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal
amount. 
 At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized
denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities issued upon any
registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or
exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906, 1107 or otherwise not involving any transfer.

 If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required
(A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice
of 

  

 24 

 
redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or
(B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities: 
 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global
Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. 
 (2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities
registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the
Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the Company fails to appoint a successor Depositary
within 90 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Depositary shall have notified the Trustee of its decision to exchange such Global Security for Securities in
certificated form or (C) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 301. 
 (3) Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all
Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct. 
 (4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or
any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person
other than the Depositary for such Global Security or a nominee thereof. 
 SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee, the Company shall execute, and the Trustee shall authenticate and deliver, in exchange therefor a
new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 If there
shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of
either of them harmless from any loss that any of them may suffer if a Security is replaced, then, in the absence of notice to the 

  

 25 

 
Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable or is to be converted, the Company in its
discretion may, instead of issuing a new Security, pay or authorize the conversion of such Security (without surrender thereof save in the case of a mutilated Security). 
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series issued pursuant to this
Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement, payment or conversion of mutilated, destroyed, lost or stolen Securities. 
 SECTION 307. Payment of Interest; Interest Rights Preserved. 
 Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to
the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be
payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the 

  

 26 

 
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 therefor to be given to each Holder of Securities of such series in the manner set forth in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close
of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
 (2) The
Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be
required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or
in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
 SECTION
308. Persons Deemed Owners. 
 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 307) any interest on such
Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 SECTION 309. Cancellation. 
 All Securities surrendered for
payment, redemption, purchase, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The
Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not 

  

 27 

 
issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange
for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order. 
 SECTION 310. Computation of Interest. 
 Except as otherwise
specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 
 ARTICLE FOUR 
 SATISFACTION AND DISCHARGE

be; 
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the

under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or 

  

 30 

 
proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or
the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property,
or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action;
or 
 (10) any other Event of Default provided with respect to Securities of that series. 
 SECTION 502. Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default (other than an Event of Default with respect to the Company specified in Section 501(8) or 501(9)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such
case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue
Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default with respect to the Company specified in Section 501(8) or 501 (9) with respect to Securities of any series at
the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the
terms thereof) shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 
 At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter
in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay 
 (A) all overdue interest on all Securities of that series, 
 (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 
  

 31 

 (C) to the extent that payment of such interest is lawful, interest upon overdue interest
at the rate or rates prescribed therefor in such Securities, and 
 (D) all sums paid or advanced by the Trustee hereunder and
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; 
 and 
 (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that
series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
 No such rescission
shall affect any subsequent default or impair any right consequent thereon. 
 SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

 The Company covenants that if 
 (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
 (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, 
 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for
principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement
of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
 SECTION 504.
Trustee May File Proofs of Claim. 
 In case of any judicial proceeding relative to the Company or the property or creditors of the Company or
any other obligor upon the Securities, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the
Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and 

  

 32 

 
receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to
the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 
 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee
may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
 SECTION 505. Trustee May Enforce Claims Without Possession of Securities. 
 All rights of action and claims
under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for
the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
 SECTION 506. Application of Money Collected.

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

 FIRST: To the payment of all amounts due the Trustee under Section 607; 
 SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities in respect of
which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively; and

 THIRD: The balance, if any, to the Company or to such other Person as a court of competent jurisdiction shall direct.

  

 33 

 SECTION 507. Limitation on Suits. 
 No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless 
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with
respect to the Securities of that series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities to be
incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer
of security or indemnity has failed to institute any such proceeding; and 
 (5) no direction inconsistent with such written
request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

 SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest. 
 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or offer by the Company to purchase the Securities
pursuant to the terms of this Indenture, on the Redemption Date or purchase date, as applicable) and, if applicable, to convert such Security in accordance with its terms, and to institute suit for the enforcement of any such right, and such rights
shall not be impaired without the consent of such Holder. 
 SECTION 509. Restoration of Rights and Remedies. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and
respectively to their former positions hereunder and thereafter all rights 

  

 34 

 
and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 SECTION 510. Rights and Remedies Cumulative. 
 Except as
otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 511. Delay or Omission Not Waiver. 
 No delay or
omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every
right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 SECTION 512. Control by Holders. 
 The Holders of a majority
in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the
Trustee, with respect to the Securities of such series, provided that 
 (1) such direction shall not be in conflict with any
rule of law or with this Indenture, and 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. 
 SECTION 513. Waiver of Past Defaults. 
 The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect
to such series and its consequences, except a default 
 (1) in the payment of the principal of or any premium or interest on
any Security of such series (including any Security which is required to have been purchased by the Company pursuant to an offer to purchase by the Company made pursuant to the terms of this Indenture), or 
  

 35 

 (2) in respect of a covenant or provision hereof which under Article Nine cannot be
modified or amended without the consent of the Holder of each Outstanding Security of such series. 
 Upon any such waiver, such default
shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

 SECTION 514. Undertaking for Costs. 
 In any
suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay
the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, however, that neither this Section nor the Trust Indenture Act shall be deemed to authorize
any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. 
 SECTION 515. Waiver of Usury, Stay or
Extension Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the
extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted. 
 ARTICLE SIX 
 THE TRUSTEE 
 SECTION 601. Certain Duties and Responsibilities. 
 The duties and responsibilities of the Trustee shall be as expressly set forth in this Indenture and as provided by the Trust Indenture Act.
Notwithstanding the foregoing, 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. 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. 
  

 36 

 SECTION 602. Notice of Defaults. 
 If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified in Section 501(5) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 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 Securities of such series. 
 SECTION 603. Certain Rights of Trustee. 
 Subject to the

 (2) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution; 
 (3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 
 (4) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
 (5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders
shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 
 (6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; and

  

 37 

 (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder. 
 SECTION 604. Not Responsible for Recitals or Issuance of Securities. 
 The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of
Securities or the proceeds thereof. 
 SECTION 605. May Hold Securities. 
 The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
 SECTION 606. Money Held in Trust. 
 Money held by the Trustee
in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company. 
 SECTION 607. Compensation and Reimbursement. 
 The Company agrees 

(1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall
not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
 (2) except as
otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 
 (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith
on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance
of any of its powers or duties hereunder. 
  

 38 

 SECTION 608. Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and
subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series. 
 SECTION 609. Corporate Trustee Required; Eligibility. 
 There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, and has a combined capital and surplus of at least $50,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 SECTION 610. Resignation
and Removal; Appointment of Successor. 
 No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this
Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 611. 
 The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series. 
 The Trustee may be removed at any time with respect to the Securities of any series by Act of
the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 
 If at any time: 
 (1) the Trustee shall fail to comply with Section 608 after written request therefor by the
Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall
cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
  

 39 

 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees. 
 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular
series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series
shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of
such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no
successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security
of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such
series and the address of its Corporate Trust Office. 
 SECTION 611. Acceptance of Appointment by Successor. 
 In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the 

  

 40 

 
retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

 In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which
(1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or
change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution
and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested
with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor
Trustee relates. 
 Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this
Article. 
 SECTION 612. Merger, Conversion, Consolidation or Succession to Business. 
 Any 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, provided such Person shall be otherwise qualified
and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the
Holders of the Securities then Outstanding. In case any Securities shall have been authenticated, but not 

  

 41 

 
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication
and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
 SECTION 613.
Preferential Collection of Claims Against Company. 
 If and when the Trustee shall be or become a creditor of the Company or any other
obligor upon the Securities, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company or any such other obligor. 
 SECTION 614. Appointment of Authenticating Agent. 
 The Trustee may appoint an Authenticating Agent or Agents
with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer, conversion or partial
redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever
reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee
by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a Person organized and doing business
under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision
or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section,
the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 
 Any Person into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any Person succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such Person shall be otherwise eligible under this Section, without the

 With the consent of the Holders of not less

and the Company, to any such supplemental indenture may be prepared and executed by the Company, and such new Securities may be authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 
 ARTICLE TEN 
 COVENANTS 
 SECTION 1001. Payment of Principal, Premium and Interest. 
 The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities
and this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11:00 A.M., New York City time, on the due date money deposited
by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. 
 SECTION
1002. Maintenance of Office or Agency. 
 The Company will maintain in each Place of Payment for any series of Securities an office or agency
where Securities of that series may be presented or surrendered for payment or, if applicable, for conversion, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company

Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 The Company may also
from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no
such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
  

 49 

 SECTION 1003. Money for Securities Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to 11:00 A.M., New York City time, on each due date of the principal of or any premium or interest on any
Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act. 
 The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and
deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a
Paying Agent and (2) during the continuance of any default by the Company or any other obligor upon the Securities of that series in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. 
 The
Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from
all further liability with respect to such money. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company,
in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense
of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, New York, notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
  

 50 

 SECTION 1004. Statement by Officers as to Default. 
 (a) The Company will deliver to the Trustee, within 90 days after the end of each fiscal year of the Company ending after the date hereof, an
Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 (b) The Company shall deliver to the Trustee, as soon as possible and in any event within five days after the Company becomes aware or should reasonably
become aware of the occurrence of an Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default, and
the action which the Company proposes to take with respect thereto. 
 SECTION 1005. Existence. 
 Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the existence, rights
(charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the
business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. 
 SECTION 1006. Maintenance of Properties.

 The Company will cause all properties used or useful in the conduct of its business to be maintained and kept in good condition, repair and
working order (reasonable wear and tear excepted) and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be
necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of
any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the Holders. 
 SECTION 1007. Payment of Taxes and Other Claims. 
 The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or upon the income, profits or property of the Company, and (2) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the property of the Company; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. 
  

 51 

 SECTION 1008. Maintenance of Insurance. 
 The Company shall keep at all times all of its properties which are of an insurable nature insured against loss or damage with insurers believed by the Company to be responsible to the extent that property of similar
character is usually so insured by corporations similarly situated and owning like properties in accordance with good business practice. 
 SECTION 1009.
Waiver of Certain Covenants. 
 Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company
may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any of Sections 1005 through 1008 or in any covenant provided pursuant to Section 301(21), 901(2) or
901(7) for the benefit of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
 ARTICLE ELEVEN 
 REDEMPTION OF SECURITIES 
 SECTION 1101. Applicability of Article. 
 Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with this Article. 
 SECTION 1102. Election to Redeem; Notice to Trustee. 
 The election of the Company to redeem any Securities
shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series (including any
such redemption affecting only a single Security), the Company shall, at least five Business Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date,
of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided
in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 
  

 52 

 SECTION 1103. Selection by Trustee of Securities to Be Redeemed. 
 If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding Securities of such series not previously called for redemption, (i) in compliance with the
requirements of the principal national securities exchange on which such Securities are listed, if such Securities are listed on any national securities exchange, and (ii) if such Securities are not so listed, on a pro rata basis, by lot or by
such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount
of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the
preceding sentence. 
 The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and,
in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. 
 The provisions of the
two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the
principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part,
to the portion of the principal amount of such Securities which has been or is to be redeemed. If any Security selected for partial redemption is surrendered for conversion after such selection, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption. Upon any redemption of less than all the Securities of a series, for purposes of selection for redemption the Company and the Trustee may treat as Outstanding Securities surrendered for
conversion during the period of 15 days next preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security authenticated and delivered during such period in exchange for the unconverted portion of any Security
converted in part during such period. 
 SECTION 1104. Notice of Redemption. 
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address
appearing in the Security Register; provided, however, notice of redemption may be given more than 60 days prior to the Redemption Date if the notice is issued in connection with a satisfaction and discharge pursuant to Article Four. 
  

 53 

 All notices of redemption shall state: 
 (1) the Redemption Date, 
 (2) the Redemption Price, if then determinable and otherwise the method of its determination, 
 (3) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the
particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed, 
 (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if
applicable, that interest thereon will cease to accrue on and after said date, 
 (5) the place or places where each such
Security is to be surrendered for payment of the Redemption Price, 
 (6) that the redemption is for a sinking fund, if such
is the case; and 
 (7) if applicable, the conversion price then in effect and the date on which the right to convert such
Securities will expire. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or,
at the Company’s request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. If any Security called for redemption is converted pursuant hereto, any money deposited with the Trustee or any Paying Agent or so
segregated and held in trust for the redemption of such Security shall be paid to the Company upon delivery of a Company Request to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such trust. 

SECTION 1105. Deposit of Redemption Price. 
 Prior to
11:00 A.M., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. 
 SECTION 1106. Securities Payable on Redemption Date. 
 Notice
of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the
payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon 

  

 54 

 
surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together
with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. 
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the Security. 
 SECTION 1107. Securities Redeemed in Part. 
 Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and deliver, to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so surrendered.

 DEFEASANCE AND COVENANT DEFEASANCE 
 SECTION 1501. Company’s Option to Effect Defeasance or Covenant Defeasance. 
 The Company may elect, at its option at any time, to have Section 1502 or Section 1503 applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 301 as
being defeasible pursuant to such Section 1502 or 1503, in accordance with any 

  

 55 

 
applicable requirements provided pursuant to Section 301 and upon compliance with the conditions set forth below in this Article. Any such election
shall be evidenced in or pursuant to a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. 
 SECTION
1502. Defeasance and Discharge. 
 Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or
any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations as provided in this Section on and after the date the conditions set forth in Section 1504 are satisfied (herein called
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 1504 and as more fully set forth in such Section, payments in respect of the principal of and any premium and
interest on such Securities when payments are due, or, if applicable, to convert such Securities in accordance with their terms, (2) the Company’s obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003,
and, if applicable, its obligations with respect to the conversion of such Securities, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to compliance with this Article, the
Company may exercise its option (if any) to have this Section applied to any Securities notwithstanding the prior exercise of its option (if any) to have Section 1503 applied to such Securities. 
 SECTION 1503. Covenant Defeasance. 
 Upon the Company’s
exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, (1) the Company shall be released from its obligations under Section 801(3), Sections 1005 through 1008,
inclusive, and any covenants provided pursuant to Section 301(21), 901(2) or 901(7) for the benefit of the Holders of such Securities and (2) the occurrence of any event specified in Sections 501(5) (with respect to any of
Section 801(3), Sections 1006 through 1008, inclusive, and any such covenants provided pursuant to Section 301(21), 901(2) or 901(7)), 501(6), 501(7)) and 501(10) shall be deemed not to be or result in an Event of Default, in each case
with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 1504 are satisfied (herein called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that,
with respect to such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 501(5)),
whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby. 
  

 56 

 SECTION 1504. Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the conditions to the application of Section 1502 or Section 1503 to any Securities or any series of Securities, as the
case may be: 
 (1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another
trustee which satisfies the requirements contemplated by Section 609 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as
security for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in
accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and
interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a direct
obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of
the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer
thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in clause (x) above and held by such bank
for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian
is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest
evidenced by such depositary receipt. 
 (2) In the event of an election to have Section 1502 apply to any Securities or
any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or
(B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities
will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and
at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 
  

 57 

 (3) In the event of an election to have Section 1503 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the
deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were
not to occur. 
 (4) The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that neither
such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 
 (5) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such
deposit or, with regard to any such event specified in Sections 501(7) and (8), at any time on or prior to the 121st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 121st
day). 
 (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the
meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 
 (7) Such
Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is bound. 
 (8) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause either the
Trustee or the trust so created to be subject to the Investment Company Act of 1940. 
 (9) The Company shall have delivered
to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
 SECTION 1505. Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1506, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 1504 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the
extent required by law. 
  

 58 

 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the U.S. Government Obligations deposited pursuant to Section 1504 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of
Outstanding Securities. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from
time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 1504 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.

 SECTION 1506. Reinstatement. 
 If the Trustee
or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 1502 or 1503 shall be revived and reinstated as though no deposit had occurred pursuant to
this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1505 with respect to such Securities in accordance with this Article; provided,
however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities
to receive such payment from the money so held in trust. 
 ARTICLE SIXTEEN 
 SINKING FUNDS 
 SECTION 1601. Applicability of Article. 
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities. 
 The minimum amount of any sinking fund payment provided for by the terms of any
Securities is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an “optional sinking fund payment.” If
provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1602. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the
terms of such Securities. 
  

 59 

 SECTION 1602. Satisfaction of Sinking Fund Payments with Securities. 
 The Company (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been (x) converted or (y) redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the
terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the
terms of such Securities; provided, however, that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as
specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
 SECTION 1603. Redemption of Securities for Sinking Fund. 
 Not less than 35 days prior to each sinking fund
payment date for any Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 1602 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 32 days prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107. 
 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original,
but all such counterparts shall together constitute but one and the same instrument.

 Dear Rob, 
 On behalf of
BigBand Networks, Inc., I am pleased to offer you the position of Vice President & General Counsel reporting to Fred Ball. You will be based in Redwood City, California, and your salary will be paid at an annual rate of $180,000.00 US dollars in
accordance with the customary payroll practices of the Company as established or modified from time to time. You shall have the opportunity to earn a Performance Bonus of $10,000.00 at your 6 month anniversary of employment and an additional
$10,000.00 at your 1 year anniversary of employment based upon successful achievement against criteria established within 30 days of your start date. In addition, you are eligible for the same benefits as other full-time vice presidents of BigBand
Networks, Inc. (including any bonus programs subsequently instituted by the company). 
 Subject to the approval by the Board of Directors,
you will be recommended to receive an option to purchase 470,000 shares of Common Stock through the Company’s stock option plan. Should the recommendation meet with the Board’s approval, the option price will also be set by the Board
during the same meeting. The options are subject to and governed by the terms and conditions of the Company’s stock option plan that includes a vesting schedule; and, by the stock option agreement executed between you and the Company. Upon
approval of this recommendation by the Board of Directors, you will receive a copy of the stock option agreement and plan for your review. 
 Due to the critical nature of the position you will serve, you are entitled to receive accelerated vesting of your stock options in the event of a change of control of the Company. You will receive the greater of (i) 12 months accelerated
vesting or (ii) 50% vesting of your then remaining unvested shares subject to you being terminated or constructively terminated by the new controlling party or not holding a comparable position within six months of the change of control. 

If your employment is terminated for any reason other than “for cause” (as defined below), you will be eligible to receive a severance
benefit in an amount equal to six months of your annual base salary as of the date of termination. In addition, the company will continue to provide the benefits plans being offered to other executives as 

 
of the date of termination for another six months. “For cause” shall be defined as a serious violation of any company policy or engaging in
criminal conduct. 
 We expect that your position at BigBand Networks will occupy your full business time. We understand that you have no
agreements that would restrict or prevent the performance of your duties for BigBand Networks. You will be required to sign, as a condition of your employment, the Nondisclosure and Developments Agreement attached hereto. You also are required by
federal law to verify work authorization status to the Company pursuant to the Immigration and Reform and Control Act of 1986. This verification must occur by your third day of employment. 
 This is not a contract of employment for a definite term of employment with the Company. As such, you or the Company for any or no reason, with or
without prior notice or cause, can terminate your employment at any time. BigBand Networks has found that an “at-will” relationship is in the best interests of both the Company and its employees. The at-will nature of your employment
relationship with the Company cannot be modified except through the execution of a written document signed by the President and CEO of the Company. 
 Your anticipated start date is expected to be February 1, 2005. I am sending you two copies of this offer letter for your convenience. Please sign one letter as your acceptance of this offer and fax to me at 650-995-0070 (Human Resources

at which time it will expire.

contributions going forward. On behalf of BigBand Networks, Inc., I am waiting to welcome you aboard. 
 Sincerely yours,
