certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. Any Opinion of Counsel may be rendered, insofar as it relates to matters of New York law, in reliance on an opinion of New
York counsel, which may be an opinion contemporaneously delivered to a third party or parties and shall expressly permit such reliance. 
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one
instrument. 
 Section 104. Acts of Holders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor
signed by such Holders in person or by agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Company. Such instrument or instruments (and the action 

  

 7 

 
embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof
of execution of any such instrument or of a writing appointing any such agent, shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided
in this Section. 
 (b) 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 in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. 
 (c) The principal amount and serial numbers of Senior Notes held by any Person, and the date of holding the same, shall be proved by the Security
Register. 
 (d) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of the Holder of any Senior
Note shall bind every future Holder of the same Senior Note and the Holder of every Senior Note 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 Senior Note. 
 (e) The fact and
date of execution of any such instrument or writing and the authority of the Person executing the same may also be proved in any other manner which the Trustee deems sufficient; and the Trustee may in any instance require further proof with respect
to any of the matters referred to in this Section. 
 (f) If the Company shall solicit from the Holders of Senior Notes of any series any
Act, the Company may, at its option, by Board Resolution, fix in advance a record date for the determination of Holders of Senior Notes entitled to take such Act, but the Company shall have no obligation to do so. Any such record date shall be fixed
at the Company’s discretion. If such a record date is fixed, such Act may be sought or given before or after the record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders of Senior
Notes for the purpose of determining whether Holders of the requisite proportion of Senior Notes of such series Outstanding have authorized or agreed or consented to such Act, and for that purpose the Senior Notes of such series Outstanding shall be
computed as of such record date. 
 Section 105. Notices, Etc., to Trustee and Company. 
 Any request, demand, authorization, direction, notice, consent, election, 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 of a Senior Note or by the
Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Services, or transmitted by facsimile 

  

 8 

 
transmission or other direct written electronic means to such telephone number or other electronic communications address as the Trustee shall from time to
time designate, or transmitted by registered or certified mail, return receipt requested, or overnight courier guaranteeing next day delivery, charges prepaid, to the Trustee, at its Corporate Trust Office, 
 (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and transmitted by facsimile transmission or other direct written electronic means to such telephone number or other electronic communications address as the Company shall from time to time designate, or transmitted by
registered or certified mail, return receipt requested, or overnight courier guaranteeing next day delivery, charges prepaid, to the Company, addressed to the attention of its Secretary, at 4902 North Biltmore Lane, Madison, WI 53718, or at any
other address previously furnished in writing to the Trustee by the Company. 
 Section 106. Notice to Holders of Senior Notes; Waiver. 
 Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of Senior Notes of any event, such notice shall be
sufficiently given 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, and not earlier than the earliest date,
prescribed for the giving of such Notice. 
 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. 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 of Senior Notes shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver. 
 Section 107. Conflict With Trust Indenture Act. 
 If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required to be a part of and govern this
Indenture, such required provision shall control. 
 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. 
  

 9 

 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 Senior Notes shall be invalid, illegal or
unenforceable, the validity, legality and enforceability 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 Senior Notes, express or implied, shall give to any Person, other than the
parties hereto, their successors hereunder and the Holders of Senior Notes any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 Section 112. Governing Law. 
 This Indenture and the Senior Notes shall be governed by, and construed in accordance with, the
internal laws of the State of New York, without regard to principles of conflicts of law. 
 Section 113. Legal Holidays. 
 In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Senior Note shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Senior Notes) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding Business Day, except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, provided that no
interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be. 
 Section 114. Waiver of Jury Trial. 
 EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE, THE SENIOR NOTES OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY. 
 Section 115. Force Majeure. 
 In no event shall the
Trustee be responsible or liable, nor shall the Company be responsible or liable to the Trustee, for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control,
including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military 

  

 10 

 
disturbances, and nuclear or natural catastrophes or acts of God; it being understood that the Trustee or the Company, as the case may be, shall use
reasonable efforts which are consistent with accepted practices to resume performance as soon as practicable under the circumstances. 
 ARTICLE TWO 
 FORMS OF SENIOR NOTES 
 Section 201. Forms Generally. 
 The Senior Notes of
each series shall be in substantially the form appended to the supplemental indenture or the Board Resolution, or the Officer’s Certificate pursuant to a supplemental indenture or a Board Resolution, authorizing such series, in each case with
such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the officers executing such Senior Notes, as evidenced by their execution of the Senior Notes. 
 The Senior Notes of each series shall be issuable in registered form without coupons. 
 The definitive Senior Notes may be printed, typewritten, lithographed or engraved on steel engraved borders or may be produced in any other manner, all
as determined by the officers executing such Senior Notes, as evidenced by their execution of such Senior Notes. 
 Section 202. Form of Trustee’s
Certificate of Authentication. 
 The form of the Trustee’s Certificate of Authentication for a series of Senior Notes shall be in
substantially the form appended to the Supplemental Indenture or the Board Resolution, or the Officer’s Certificate pursuant to a supplemental indenture or a Board Resolution, authorizing such series. 
 Section 203. Senior Notes Issuable in the Form of a Global Security. 
 (a) If the Company shall establish pursuant to Section 301 that the Senior Notes of a particular series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall
execute and the Trustee shall, in accordance with Section 302 and the Company Order delivered to the Trustee thereunder, authenticate and deliver such Global Security or Securities, which (i) shall represent, and shall be denominated in an
amount equal to the aggregate principal amount of the Outstanding Senior Notes of such series to be represented by such Global Security or Securities, (ii) may provide that the aggregate amount of Outstanding Senior Notes represented thereby
may from time to time be increased or reduced to reflect exchanges, (iii) shall be registered in the name of the Depositary for such Global Security or Securities or its nominee, (iv) shall be delivered by the Trustee to the Depositary or
pursuant to the Depositary’s instruction and (v) shall bear a legend in accordance with the requirements of the Depositary. 
  

 11 

 (b) Notwithstanding any other provision of this Section 203 or of Section 303, subject to the
provisions of paragraph (c) below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for individual Senior Notes, a Global Security may be transferred, in whole but not in part and
in the manner provided in Section 303, only to a nominee of the Depositary for such Global Security, or to the Depositary, or to a successor Depositary for such Global Security selected or approved by the Company, or to a nominee of such
successor Depositary. 
 (c) (1) If at any time the Depositary for a Global Security notifies the Company that it is unwilling or unable
to continue as Depositary for such Global Security or if at any time the Depositary for the Senior Notes for such series shall no longer be eligible or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable
statute or regulation, the Company shall appoint a successor Depositary with respect to such Global Security. If a successor Depositary for such Global Security is not appointed by the Company within 90 days after the Company receives such notice or
becomes aware of such ineligibility, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Senior Notes of such series in exchange for such Global Security, will authenticate and
deliver individual Senior Notes of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Security in exchange for such Global Security. 
 (2) The Company may at any time and in its sole discretion determine that the Senior Notes of any series issued or issuable in the form of
one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event the Company will execute, and the Trustee, upon receipt of a Company Request for the authentication and delivery of individual Senior
Notes of such series in exchange in whole or in part for such Global Security, will authenticate and deliver individual Senior Notes of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal
amount of such Global Security or Securities representing such series in exchange for such Global Security or Securities. 
 (3) If specified by the Company pursuant to Section 301 with respect to Senior Notes issued or issuable in the form of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole
or in part for individual Senior Notes of such series of like tenor and terms in definitive form on such terms as are acceptable to the Company and such Depositary. Thereupon the Company shall execute, and, upon receipt of a Company Request for the
authentication and delivery of individual Senior Notes of such series in exchange in whole or in part for such Global Security, the Trustee shall authenticate and deliver (A) to each Person specified by such Depositary a new Senior Note or
Notes of the same series of like tenor and terms and of any authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and (B) to
such Depositary a new Global Security of like tenor and terms and in an authorized denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Senior Notes
delivered to Holders thereof. 
  

 12 

 (4) In any exchange provided for in any of the preceding three paragraphs, the Company
will execute and the Trustee will authenticate and deliver individual Senior Notes in definitive form in authorized denominations. Upon the exchange of the entire principal amount of a Global Security for individual Senior Notes, such Global
Security shall be cancelled by the Trustee. Except as provided in the preceding paragraph, Senior Notes issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the
Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Provided that the Company has so directed in writing, the Trustee shall deliver such Senior Notes to the
Persons in whose names the Senior Notes are registered. 
 (5) Any endorsement of a Global Security to reflect the amount, or
any increase or decrease in the amount, or changes in the rights of Holders, of Outstanding Senior Notes represented thereby shall be made in such manner and by such Person or Persons as shall be specified therein or in the Company Order to be
delivered pursuant to Section 302 with respect thereto. Subject to the provisions of Section 302, the Trustee shall deliver and redeliver any such Global Security in the manner and upon instructions given by the Person or Persons specified
therein or in the applicable Company Order. If a Company Order pursuant to Section 302 has been, or simultaneously is, delivered, any instructions by the Company with respect to such Global Security shall be in writing but need not be
accompanied by or contained in an Officer’s Certificate and need not be accompanied by an Opinion of Counsel.

 Section 302. Execution, Authentication, Delivery and Dating. 
 The Senior Notes shall be executed on behalf of the Company by any two of the following: the President, the Chief Executive Officer, any Vice President, the Chief Financial Officer, the Treasurer or any Assistant Treasurer, or the Secretary
or any Assistant Secretary. The corporate seal of the Company, if any, may be affixed thereto or reproduced thereon and attested by the Secretary of the Company or any Assistant Secretary of the Company. The signature of any of these officers on the
Senior Notes may be manual or facsimile. 
  

 16 

 Senior Notes bearing the manual or facsimile signatures of individuals who were at the time relevant to
the authorization thereof 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 Senior Notes or did not hold
such offices at the date of such Senior Notes. 
 At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Senior Notes of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Senior Notes, and the Trustee, in accordance with the Company Order,
shall authenticate and deliver such Senior Notes. If all of the Senior Notes of any series are not to be issued at one time and if the supplemental indenture or the Board Resolution, or the Officer’s Certificate pursuant to a supplemental
indenture or a Board Resolution, establishing such series shall so permit, such Company Order may set forth procedures reasonably acceptable to the Trustee for the issuance of such Senior Notes and determining the terms of particular Senior Notes of
such series, such as interest rate, maturity date, date of issuance and date from which interest shall accrue. In authenticating Senior Notes hereunder, and accepting the additional responsibilities under this Indenture in relation to such Senior
Notes, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon: 
 (1) an Opinion of Counsel, to the effect that the form and terms of such Senior Notes or the manner of determining such terms have been established in conformity with the provisions of this Indenture, that the Indenture and such Senior
Notes, 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 binding obligations of the Company enforceable in accordance
with their terms, subject to bankruptcy, insolvency, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles (regardless of whether enforcement is
considered in a proceeding in equity or at law), except, however, for the possibility that certain provisions of the Indenture and the Senior Notes may not be enforceable, although the inclusion of such provisions does not affect the validity of the
Indenture and the Senior Notes and the Indenture and the Senior Notes contain legally adequate provisions for the realization of the principal legal rights and benefits offered thereby; that the execution and delivery by the Company of the Senior
Notes will not result in any violation of any applicable law, statute, rule or regulation of any U.S., Wisconsin or New York government or government instrumentality having jurisdiction over the Company; and that the Company has complied with all
conditions precedent under the Indenture to the authentication and delivery of the Senior Notes; and 
 (2) an Officer’s
Certificate stating, to the knowledge of the signer of such certificate, that no Event of Default, or event which is, or after notice or lapse of time or both would become, an Event of Default, with respect to any of the Senior Notes shall have
occurred and be continuing. 
 The Trustee shall not be required to authenticate such Senior Notes if the issue of such Senior Notes pursuant to this
Indenture will affect the Trustee’s own rights, duties or immunities under the Senior Notes and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 
  

 17 

 If all the Senior Notes of any series are not to be issued at one time, it shall not be necessary to
deliver an Opinion of Counsel and Officer’s Certificate at the time of issuance of each such Senior Note, but such opinion and certificate shall be delivered at or before the time of issuance of the first Senior Note of such series to be
issued. 
 Each Senior Note shall be dated the date of its authentication. 
 No Senior Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Senior Note a
certificate of authentication executed by the Trustee by manual signature, and such certificate upon any Senior Note shall be conclusive evidence, and the only evidence, that such Senior Note has been duly authenticated and delivered hereunder and
is entitled to the benefits of this Indenture. 
 Section 303. Registration, Registration of Transfer and Exchange. 
 The Company shall cause to be kept at the office of the Security Registrar designated pursuant to this Section 303 or Section 1002 a register
(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 Senior Notes and of transfers of Senior Notes. The Trustee is hereby initially
appointed as Security Registrar for the purpose of registering Senior Notes and transfers of Senior Notes as herein provided. 
 Subject to
Section 203, upon surrender for registration of transfer of any Senior Note of any series at the office or agency maintained for such purpose for such series, the Company shall execute, and, as directed by the Company, the Trustee shall
authenticate and deliver, in the name of the designated transferee or transferees, one or more new Senior Notes of the same series, Stated Maturity and original issue date, of any authorized denominations and of like tenor and aggregate principal
amount. 
 Subject to Section 203, Senior Notes of any series may be exchanged, at the option of the Holder, for Senior Notes of the
same series, Stated Maturity and original issue date, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Senior Notes to be exchanged at any such office or agency. 
 Whenever any Senior Notes are so surrendered for exchange, the Company shall execute, and, as directed by the Company, the Trustee shall authenticate and
deliver, the Senior Notes that the Holder making the exchange is entitled to receive. 
 All Senior Notes issued upon any registration of
transfer or exchange of Senior Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Senior Notes surrendered upon such registration of transfer or exchange.

 Every Senior Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company) 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 Senior Notes, 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 Senior Notes, other than exchanges pursuant to Sections 304, 907 or 1107
not involving any transfer. 
 The Company shall not be required (i) to issue, to register the transfer of or to exchange Senior Notes
of any series during a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Senior Notes of that series called for redemption, or (ii) to issue, to register the transfer of or to exchange any
Senior Notes so selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 
 None
of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 Section 304. Mutilated, Destroyed, Lost and Stolen
Senior Notes. 
 If any mutilated Senior Note is surrendered to the Trustee, the Company shall execute and, as directed by the Company,
the Trustee shall authenticate and deliver in exchange therefor a new Senior Note of the same series, Stated Maturity and original issue date, 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 Senior
Note and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Senior Note has been acquired by a
protected purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Senior Note, a new Senior Note of the same series, Stated Maturity and original issue date,
and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost
or stolen Senior Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Senior Note, pay such Senior Note and provide the Trustee with a Company Order to cancel such Senior Note.

 Upon the issuance of any new Senior Note 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 Senior Note of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Senior Note shall constitute an original additional contractual obligation of the Company, whether or not
the destroyed, lost or stolen Senior Note shall be at any time enforceable by anyone, and any such new Senior Note shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Senior Notes of that series
duly issued hereunder. 
  

 19 

 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights
and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Senior Notes. 
 Section 305. Payment of Interest;
Interest Rights Preserved. 
 Unless otherwise provided as contemplated by Section 301 with respect to any series of Senior Notes,
interest on any Senior Note that 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 Senior Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest. 
 Any interest on any Senior Note of any series that 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 Senior Notes of such series (or their respective Predecessor Notes) 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 Senior Note of such series and the date of the
proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this Clause. 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
mailed, first-class postage prepaid, to each Holder of Senior Notes of such series at the address of such Holder as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Senior Notes of such series (or their respective Predecessor Notes) 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 Senior Notes of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Senior Notes may be listed, and upon such notice as may be
required by such exchange, and after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause that such manner of payment has been deemed practicable by the Company. 
  

 20 

 Subject to the foregoing provisions of this Section, each Senior Note delivered under this Indenture upon
registration of transfer of or in exchange for or in lieu of any other Senior Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Senior Note. 
 Section 306. Persons Deemed Owners. 
 Prior to due
presentment of a Senior Note 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 Senior Note is registered, including the Depositary or its nominee, as the
absolute owner of such Senior Note for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 305) interest on such Senior Note and for all other purposes whatsoever, whether or not such Senior Note 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 307.
Cancellation. 
 All Senior Notes surrendered for payment, redemption, registration of transfer or exchange or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Senior Notes
previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Senior Notes so delivered shall be promptly canceled by the Trustee. No Senior Notes shall be authenticated in lieu of or in
exchange for any Senior Notes canceled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Senior Notes held by the Trustee shall be disposed of in accordance with its customary procedures (subject to any
record retention requirements of the Securities Exchange Act of 1934, as amended). The Trustee shall promptly deliver a certificate of disposition to the Company upon request. 
 Section 308. Computation of Interest. 
 Except as otherwise specified as contemplated by
Section 301 for Senior Notes of any series, interest on the Senior Notes of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months. 
 ARTICLE FOUR 
 SATISFACTION AND DISCHARGE

 Section 401. Satisfaction and Discharge of Senior Notes. 
 Any Senior Note or Senior Notes, or any portion of the principal amount thereof, shall be deemed to have been paid and no longer Outstanding for all purposes of this Indenture, and the 

  

 21 

 
entire indebtedness of the Company in respect thereof shall be satisfied and discharged, if there shall have been irrevocably deposited with the Trustee or
any Paying Agent (other than the Company), in trust: 
 (a) money in an amount which shall be sufficient, or 
 (b) in the case of a deposit made prior to the Maturity of such Senior Notes or portions thereof, Eligible Obligations, which shall not contain
provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide moneys which, together with the
money, if any, deposited with or held by the Trustee or such Paying Agent, shall be sufficient, or 
 (c) a combination of (a) or
(b) which shall be sufficient to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Senior Notes or portions thereof; provided, however, that in the case of the provision for payment or
redemption of less than all the Senior Notes of any series, such Senior Notes or portions thereof shall have been selected by the Security Registrar as provided herein and, in the case of a redemption, the notice requisite to the validity of such
redemption shall have been given or irrevocable authority shall have been given by the Company to the Trustee to give such notice, under arrangements satisfactory to the Trustee; and provided, further, that the Company shall have delivered to the
Trustee and such Paying Agent: 
 (x) if such deposit shall have been made prior to the Maturity of such Senior Notes, a
Company Order stating that the money and Eligible Obligations deposited in accordance with this Section shall be held in trust, as provided in Section 403; 
 (y) if Eligible Obligations shall have been deposited, an Opinion of Counsel that the obligations so deposited constitute Eligible
Obligations and do not contain provisions permitting the redemption or other prepayment at the option of the issuer thereof, and an opinion of an independent public accountant or a firm of independent public accountants, selected by the Company and
as reasonably acceptable to the Trustee, to the effect that the requirements set forth in clause (b) above have been satisfied; and 
 (z) if such deposit shall have been made prior to the Maturity of such Senior Notes, (i) an Officer’s Certificate stating the Company’s intention that, upon delivery of such Officer’s Certificate,
its indebtedness in respect of such Senior Notes or portions thereof will have been satisfied and discharged as contemplated in this Section, and (ii) an Opinion of Counsel to the effect that, as a result of a change in law occurring or a
ruling of the United States Internal Revenue Service issued after the date of issuance of such Senior Notes, the Holders of such Senior Notes, or portions of the principal amount thereof, will not recognize income, gain or loss for United States
federal income tax purposes as a result of the satisfaction and discharge of the Company’s indebtedness in respect thereof and will be subject to United States federal income tax on the same amounts, at the same times and in the same manner as
if such satisfaction and discharge had not been effected. 
  

 22 

 Upon the deposit of money or Eligible Obligations, or both, in accordance with this Section, together
with the documents required by clauses (x), (y) and (z) above, the Trustee shall, upon receipt of a Company Request, acknowledge in writing that the Senior Notes or portions thereof with respect to which such deposit was made are deemed to
have been paid for all purposes of this Indenture and that the entire indebtedness of the Company in respect thereof has been satisfied and discharged as contemplated in this Section. In the event that all of the conditions set forth in the
preceding paragraph shall have been satisfied in respect of any Senior Notes or portions thereof except that, for any reason, the Officer’s Certificate and Opinion of Counsel specified in clause (z) shall not have been delivered, such
Senior Notes or portions thereof shall nevertheless be deemed to have been paid for all purposes of this Indenture, and the Holders of such Senior Notes or portions thereof shall nevertheless be no longer entitled to the benefits of this Indenture
or of any of the covenants of the Company under Article Ten (except the covenants contained in Sections 1002 and 1003) or any other covenants made in respect of such Senior Notes or portions thereof as contemplated by Section 301, but the
indebtedness of the Company in respect of such Senior Notes or portions thereof shall not be deemed to have been satisfied and discharged prior to Maturity for any other purpose, and the Holders of such Senior Notes or portions thereof shall
continue to be entitled to look to the Company for payment of the indebtedness represented thereby; and, upon Company Request, the Trustee shall acknowledge in writing that such Senior Notes or portions thereof are deemed to have been paid for all
purposes of this Indenture. 
 If payment at Stated Maturity of less than all of the Senior Notes of any series is to be provided for in the
manner and with the effect provided in this Section, the Security Registrar shall select such Senior Notes, or portions of principal amount thereof, in the manner specified by Section 1103 for selection for redemption of less than all the
Senior Notes of a series. 
 In the event that Senior Notes which shall be deemed to have been paid for purposes of this Indenture, and, if
such is the case, in respect of which the Company’s indebtedness shall have been satisfied and discharged, all as provided in this Section, do not mature and are not to be redeemed within the 60-day period commencing with the date of the
deposit of moneys or Eligible Obligations, as aforesaid, the Company shall, as promptly as practicable, give a notice, in the same manner as a notice of redemption with respect to such Senior Notes, to the Holders of such Senior Notes to the effect
that such deposit has been made and the effect thereof. 
 Notwithstanding that any Senior Notes shall be deemed to have been paid for
purposes of this Indenture, as aforesaid, the obligations of the Company and the Trustee in respect of such Senior Notes under Sections 303, 304, 603, 607, 614, 1002, 1003 and 1104 and this Article Four shall survive. 
 The Company shall pay, and shall indemnify the Trustee or any Paying Agent with which Eligible Obligations shall have been deposited as provided in this
Section against, any tax, fee or other charge imposed on or assessed against such Eligible Obligations or the principal or interest received in respect of such Eligible Obligations, including any such tax payable by any entity deemed, for tax
purposes, to have been created as a result of such deposit. 
  

 23 

 Anything herein to the contrary notwithstanding, (a) if, at any time after a Senior Note would be
deemed to have been paid for purposes of this Indenture, and, if such is the case, the Company’s indebtedness in respect thereof would be deemed to have been satisfied or discharged, pursuant to this Section (without regard to the provisions of
this paragraph), the Trustee or any Paying Agent, as the case may be, shall be required to return the money or Eligible Obligations, or combination thereof, deposited with it as aforesaid to the Company or its representative under any applicable
federal or state bankruptcy, insolvency or other similar law, such Senior Note shall thereupon be deemed retroactively not to have been paid and any satisfaction and discharge of the Company’s indebtedness in respect thereof shall retroactively
be deemed not to have been effected, and such Senior Note shall be deemed to remain Outstanding and (b) any satisfaction and discharge of the Company’s indebtedness in respect of any Senior Notes shall be subject to the provisions of
Section 403. 
 Section 402. Satisfaction and Discharge of Indenture. 
 This Indenture shall, upon Company Request, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of
Senior Notes herein expressly provided for) and the Trustee, at the expense and request of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when 
 (1) no Senior Notes remain Outstanding hereunder; 
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
 (3) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with; 
 provided, however, that if, in
accordance with the last paragraph of Section 401, any Senior Note previously deemed to have been paid for purposes of this Indenture, shall be deemed retroactively not to have been so paid, this Indenture shall thereupon be deemed
retroactively not to have been satisfied and discharged, as aforesaid, and to remain in full force and effect, and the Company shall execute and deliver such instruments as the Trustee shall reasonably request to evidence and acknowledge the same.

 In the event there are Senior Notes of two or more series hereunder, the Trustee shall be required to execute an instrument acknowledging
satisfaction and discharge of this Indenture only if requested to do so by the Company with respect to Senior Notes of all series as to which it is Trustee and if the other conditions thereto are met. In the event there are two or more Trustees
hereunder, then the effectiveness of any such instrument shall be conditioned upon receipt of such instruments from all Trustees hereunder. 
 Notwithstanding the satisfaction and discharge of this Indenture as aforesaid, the obligations of the Company and the Trustee in respect of such Senior Notes under Sections 303, 304, 603, 607, 614, 1002, 1003 and 1104 and this Article Four
shall survive. 
  

 24 

 Section 403. Application of Trust Money. 
 Neither the Eligible Obligations nor the money deposited pursuant to Section 401, nor the principal or interest payments on any such Eligible
Obligations, shall be withdrawn or used for any purpose other than, and shall be held in trust for, the payment of the principal of and premium, if any, and interest, if any, on the Senior Notes or portions of principal amount thereof in respect of
which such deposit was made, all subject, however, to the provisions of Section 1003; provided, however, that any cash received from such principal or interest payments on such Eligible Obligations, if not then needed for such purpose, shall,
to the extent practicable and upon Company Request and delivery to the Trustee of the documents referred to in subclause (y) of clause (c) in Section 401, be invested pursuant to a Company Order in Eligible Obligations of the type
described in clause (b) in Section 401 maturing at such times and in such amounts as shall be sufficient, together with any other moneys and the proceeds of any other Eligible Obligations then held by the Trustee, to pay when due the
principal of and premium, if any, and interest, if any, due and to become due on such Senior Notes or portions thereof on and prior to the Maturity thereof, and interest earned from such reinvestment shall be paid over to the Company as received,
free and clear of any trust, lien or pledge under this Indenture except the lien provided by Section 607; and provided, further, that any moneys held in accordance with this Section on the Maturity of all such Senior Notes in excess of the
amount required to pay the principal of and premium, if any, and interest, if any, then due on such Senior Notes shall be paid over to the Company free and clear of any trust, lien or pledge under this Indenture except the lien provided by
Section 607. 
 ARTICLE FIVE

 “Event of Default”, wherever used herein with respect to Senior Notes of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or

 (4) default in the performance or breach of any covenant or warranty of the Company in
this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of one or more series
of Senior Notes other than that series), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail or sent via overnight delivery, to the Company by the Trustee, or to the Company
and the Trustee by the Holders of at least 33% in principal amount of the Outstanding Senior Notes of that series, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of
Default” hereunder, unless the Holders of a principal amount of Senior Notes of such series not less than the principal amount of Senior Notes the Holders of which gave such notice shall agree in writing to an extension of such period prior to
its expiration; or 
 (5) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in
respect of the Company in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving
as properly filed a petition by one or more Persons other than the Company seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable federal or state law, or appointing a custodian, receiver,
liquidator, assignee, trustee, sequestrator or other similar official for the Company or for any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief
or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or 
 (6) the commencement by
the Company of a case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of

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 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 
 (7) any other Event of Default specified by
the Company pursuant to Section 301 with respect to Senior Notes of that series. 
 Section 502. Acceleration of Maturity; Rescission and
Annulment. 
 If an Event of Default with respect to Senior Notes 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 33% in principal amount of the Outstanding Senior Notes of that series may declare the principal amount (or such portion of the principal amount as may be specified in the terms of that
series) of all of the Senior Notes of that series to be due and payable immediately, by a notice in writing to the Company (and to the Company and the Trustee if given by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable. 
  

 26 

 At any time after such a declaration of acceleration with respect to Senior Notes of any series has been
made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a majority in principal amount of the Outstanding Senior Notes 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 Senior Notes of that
series, 
 (B) the principal of (and premium, if any) any Senior Notes of that series which have become due otherwise than by
such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Senior Notes, 
 (C) to
the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Senior Notes, 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 any other amounts due to the Trustee under
Section 607; and 
 (2) all Events of Default with respect to Senior Notes of that series, other than the non-payment of
the principal of Senior Notes of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 
 Section 503. Collection
of Indebtedness and Suits for Enforcement by Trustee. 
 The Company covenants that if an Event of Default occurs under
Section 501(1), (2) or (3) with respect to any Senior Notes the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Senior Notes, the whole amount then due and payable on such Senior Notes for
principal (and premium, if any) and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates prescribed therefor
in such Senior Notes, 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, and any other amounts due to the Trustee under Section 607. 
 If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against
the Company or any other obligor upon such Senior Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Senior Notes, wherever situated.

  

 27 

 If an Event of Default with respect to Senior Notes of any series occurs and is continuing, the Trustee
may in its reasonable discretion proceed to protect and enforce its rights and the rights of the Holders of Senior Notes of such series by such appropriate judicial proceedings as the Trustee shall deem in its reasonable judgment to be 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 the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Senior Notes or the property of
the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Senior Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, 
 (1) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the
Senior Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due to the Trustee under Section 607) and of the Holders of Senior Notes allowed in such judicial proceeding, and 
 (2) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Senior Notes to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the Holders of Senior Notes, 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. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Senior Note any plan of reorganization, arrangement, adjustment or
composition affecting the Senior Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Senior Note in any such proceeding. 
  

 28 

 Section 505. Trustee May Enforce Claims Without Possession of Senior Notes. 
 All rights of action and claims under this Indenture or the Senior Notes may be prosecuted and enforced by the Trustee without the possession of any of
the Senior Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name or 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 Senior Notes in respect of which such judgment has been recovered.

 Section 506. Application of Money Collected. 
 After an Event of Default, any money or other property distributable in respect of the Company’s obligations under this Indenture 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 premium, if any) or interest, upon presentation of the Senior Notes, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
 First: To the payment of all amounts due the Trustee (including any predecessor Trustee) for amounts due under Section 607; and

 Second: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Senior
Notes 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 Senior Notes for principal (and premium, if any) and interest,
respectively; and 
 Third: The balance, if any, to the Company or any other Person or Persons entitled thereto. 

Section 507. Limitation on Suits. 
 No Holder of
any Senior Note 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 Senior Notes of
that series; 
 (2) the Holders of not less than a majority in principal amount of the Outstanding Senior Notes 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 indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
  

 29 

 (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 Senior Notes of that series; 
 it being understood and
intended that no one or more of such Holders shall have any right in any manner whatsoever 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. The Trustee shall mail to all
Holders any notice it receives from Holders under this Section. 
 Section 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest. 
 Notwithstanding any other provision in this Indenture, the Holder of any Senior Notes shall have the right, which is absolute
and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 305) interest on such Senior Note on the due dates expressed in such Senior Note (or, in the case of redemption, on the Redemption Date) and
to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 Section 509.
Restoration of Rights and Remedies. 
 If the Trustee or any Holder of a Senior Note 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 of Senior Notes shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted. 
 Section 510. Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Senior Notes in the last paragraph of
Section 304, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Senior Notes 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 Senior Note to exercise any right or remedy 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 of Senior Notes may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders of Senior Notes.

 Section 512. Control by Holders of Senior Notes. 
 The Holders of not less than a majority in principal amount of the Outstanding Senior Notes 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 Senior Notes of such series; provided, however, that the Trustee shall have the right to
decline to follow any such direction from the Holders if the Trustee, being advised by counsel, determines that the action or proceedings so directed may not lawfully be taken or if the Trustee in good faith shall, by Responsible Officers, determine
that the action or proceedings so directed would involve the Trustee in personal liability, or would be unduly prejudicial to the Holders of the Senior Notes of such series not joining in such direction, it being understood that the Trustee shall
have no duty to ascertain whether or not such actions or forebearances are unduly prejudicial to such Holders, and 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 Senior Notes of any series may, on behalf of the Holders of all the Senior Notes 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 premium, if any) or interest on any Senior Note of such series,
or 
 (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the
consent of the Holder of each Outstanding Senior Note of such series affected. 
 Upon any such waiver, such default shall cease to exist,
and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 Section 514. Undertaking for Costs. 
 All parties to
this Indenture agree, and each Holder of any Senior Note by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit
instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Senior Notes of any series, or to any suit
instituted by any Holder of any Senior Note for the enforcement of the 

  

 31 

 
payment of the principal of (or premium, if any) or interest on any Senior Note on or after the Stated Maturity or Maturities expressed in such Senior Note
(or, in the case of redemption, on or after the Redemption Date). 
 Section 515. Waiver of 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 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

 (a) Except during the continuance of an Event of Default with respect to Senior Notes of any series, 
 (1) the Trustee undertakes to perform, with respect to Senior Notes of such series, such duties and only such duties as are specifically
set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad faith on its part, the Trustee may, with respect to Senior Notes of such series, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or
opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be
under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture. 
 (b) In case an Event of
Default with respect to Senior Notes of any series has occurred and is continuing, the Trustee shall exercise, with respect to Senior Notes of such series, such of the rights and powers vested in it by this Indenture, and use the same degree of care
and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 
 (c) No
provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that 
 (1) this Subsection shall not be construed to limit the effect of Subsection (a) of this Section; 
  

 32 

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

Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Senior Notes of any series relating to the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Senior Notes of such series; and 
 (4) 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. 
 (d) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting
the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
 Section 602. Notice of Defaults.

 Within 90 days after the occurrence of any default hereunder with respect to the Senior Notes of any series about which the Trustee shall
have knowledge as set forth in Section 603(h) hereof, the Trustee shall transmit by mail to all Holders of Senior Notes of such series entitled to receive reports pursuant to Section 313(c) of the Trust Indenture Act, notice of all
defaults hereunder known to the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on any Senior Note of such
series or in the payment of any sinking fund deposit with respect to Senior Notes of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of
directors or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of Senior Notes of such series; and provided, further, that in the case of any default of the character
specified in Section 501(4) with respect to Senior Notes of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event

which might be incurred by it in compliance with such request or direction; 
 (f) 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 (subject to applicable legal
requirements) be entitled to examine during normal business hours the books, records and premises of the Company, personally or by agent or attorney; 
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any
misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder, and the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be compensated,
reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder; and 
 (h) the Trustee shall not be charged with knowledge of any Event of Default, or any event which is, or after notice or lapse of time or both
would become an Event of Default, with respect to the Senior Notes of any series for which it is acting as Trustee unless either (1) a Responsible Officer of the Trustee assigned to the Corporate Trust Office (or any successor division or
department of the Trustee) shall have actual knowledge of the event or Event of Default or (2) written notice of such event or Event of Default shall have been given to the Trustee by the Company, any other obligor on such Senior Notes or by
any Holder of such Senior Notes. 
 Section 604. Not Responsible for Recitals or Issuance of Senior Notes. 
 The recitals contained herein and in the Senior Notes (except the Trustee’s certificates of authentication) shall be taken as the
statements of the Company, and the Trustee or any Authenticating Agent assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Senior Notes. The Trustee or

 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 Senior Notes and, subject to Sections 608 and 613, may otherwise deal with the Company and its Affiliates 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 in writing 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), as more fully set forth in a letter agreement between the Company and the Trustee; 
 (2) 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, willful misconduct or bad faith; and 
 (3) to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, willful misconduct 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.

such, except funds held in trust for the payment of principal of, premium, if any, or interest, if any, on any Senior Notes in accordance with the provisions of this Indenture. 
 When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(5) or
Section 501(6), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute

  

 35 

 
expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law. The provisions of this Section shall survive
the satisfaction and discharge or termination of this Indenture, the resignation or removal of the Trustee, and the defeasance of the Senior Notes. 
 Section 608. Disqualification; Conflicting Interests. 
 If the Trustee has or shall acquire any conflicting interest, within
the meaning of the Trust Indenture Act, it shall, within 90 days after ascertaining that it has such conflicting interest, either eliminate such conflicting 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 the Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest with respect to any other indenture of the Company or Senior Notes of any
series by virtue of being a trustee under this Indenture with respect to any particular series of Senior Notes. 
 Section 609. Corporate Trustee
Required; Eligibility. 
 There shall at all times be a Trustee hereunder which shall be a corporation organized and doing business under
the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, subject to supervision or
examination by federal or state authority and qualified and eligible under this Article and otherwise permitted by the Trust Indenture Act to act as Trustee under an Indenture qualified under the Trust Indenture Act. If such corporation 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 corporation shall be deemed to be its combined
capital surplus as set forth in its most recent report of condition so published. If at any time the Trustee 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. 
 (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 611. 
 (b) The Trustee may
resign at any time with respect to the Senior Notes 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 Senior Notes of such series. 
 (c) The Trustee may be removed at any time with respect to the Senior Notes of any series by Act of the Holders of a majority in principal amount of the
Outstanding Senior Notes of such series delivered to the Trustee and to the Company. 
  

 36 

 (d) 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 of a Senior Note
who has been a Holder of a Senior Note for at least six months, or 
 (2) the Trustee shall cease to be eligible under
Section 609 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
 (3) the
Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs
for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee with respect to all Senior Notes, or (ii) subject to Section 514, any Holder of a Senior Note who has been a bona fide Holder of a Senior Note 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 Senior Notes and the appointment of a successor Trustee or Trustees. 
 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Senior Notes of one or more series, the Company shall
promptly appoint a successor Trustee or Trustees with respect to the Senior Notes of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Senior Notes of one or more or all of such series and
that at any time there shall be only one Trustee with respect to the Senior Notes 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 Senior Notes of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Senior Notes 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 Senior Notes
of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Senior Notes of any series shall have been so appointed by the Company or the Holders of Senior Notes and
accepted appointment in the manner required by Section 611, any Holder of a Senior Note who has been a bona fide Holder of a Senior Note 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 Senior Notes of such series. 
 (f) So long as no Event of Default, or no event which is, or after notice or lapse of time, or both, would become, an Event of Default, shall have occurred and be continuing, and except with respect to a Trustee appointed by the Act of the
Holders of a majority in principal amount of the Outstanding Senior Notes pursuant to any series pursuant to subsection (c) above, if the Company shall have delivered to the Trustee (1) a Board Resolution appointing a successor Trustee,
effective as of a date specified therein, and (2) an instrument of acceptance of such appointment, effective as of such date, by such successor Trustee in accordance with Section 611, 

  

 37 

 
then the Trustee shall be deemed removed as contemplated by subsection (d) above, the successor Trustee shall be deemed to have been appointed by the
Company pursuant to subsection (e) above and such appointment shall be deemed to have been accepted as contemplated in Section 611, all as of such date, and all other provisions of this Section and Section 611 shall be applicable to
such removal, appointment and acceptance except to the extent inconsistent with this subsection (f). 
 (g) The Company or the successor
Trustee shall give notice of each resignation and each removal of the Trustee with respect to the Senior Notes of any series and each appointment of a successor Trustee with respect to the Senior Notes of any series by mailing written notice of such
event by first-class mail, postage prepaid, to all Holders of such series of Senior Notes as their names and addresses appear in the Security Register. 
 Section 611. Acceptance of Appointment by Successor. 
 (a) In case of the appointment hereunder of a successor Trustee with
respect to all Senior Notes, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 
 (b) In case of the appointment hereunder
of a successor Trustee with respect to the Senior Notes of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Senior Notes 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
(other than such rights in Section 607 hereof relating to indemnities arising prior to the effective date of appointment of a successor Trustee), powers, trusts and duties of the retiring Trustee with respect to the Senior Notes 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 Senior Notes, 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 Senior Notes 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, 

  

 38 

 
trusts and duties of the retiring Trustee with respect to the Senior Notes 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 Senior Notes
of that or those series to which the appointment of such successor Trustee relates. 
 (c) Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

 (d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
 Section 612. Merger, Conversion, Consolidation or Succession to Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation
shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Senior Notes shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Senior Notes so authenticated with the same effect as if such successor Trustee had itself
authenticated such Senior Notes. 
 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 Senior Notes), 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). For purposes of Section 311(b)(4) and (6) of the Trust Indenture Act: 
 (a) “cash transaction” means any transaction in which full payment for goods or securities sold is made within seven days after delivery of the
goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand; and 
 (b)
“self-liquidating paper” means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by the Company (or any such obligor) for the purpose of financing the purchase, processing, manufacturing,
shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares
or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company (or any such obligor) arising from the making, drawing, negotiating
or incurring of the draft, bill of exchange, acceptance or obligation. 
  

 39 

 Section 614. Appointment of Authenticating Agent. 
 At any time when any of the Senior Notes remain Outstanding the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Senior Notes that shall be authorized to act on behalf of the Trustee to authenticate Senior Notes of such series issued upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 304, and Senior Notes 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
Senior Notes by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed
on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating
Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 
 Any corporation into which an
Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable
to the Company and the Trustee shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Senior Notes, if any, of the series with respect to which such Authenticating Agent will serve, as their names and
addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally
named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
  

 40 

 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its
services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607. 
 The provisions of Sections 306, 604 and 605 shall be applicable to each Authenticating Agent. 
 If an appointment with respect to
one or more series is made pursuant to this Section, the Senior Notes of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

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

 The Company will be responsible for making calculations called for under the terms of the Senior Notes. These calculations include, but are not limited
to, determination of Redemption Price (including make-whole amounts or premiums, if any), original issue discount, if any, and conversion rates and adjustments, if any. The Company will make the calculations in good faith and, absent manifest error,
its calculations will be final and binding on the Holders of the Senior Notes. The Company will provide a schedule of its calculations to the Trustee when applicable, and the Trustee is entitled to rely conclusively on the accuracy of the
Company’s calculations without independent verification.

Senior Notes, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Senior Notes of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents for any series of Senior Notes, it will, prior to each due date of the principal of (and
premium, if any) or interest on any Senior Notes of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, 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 Senior Notes 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:

otherwise disposed of as herein provided;

upon the Senior Notes of that series) to make any payment of principal of (and premium, if any) or interest on the Senior Notes of that series; and 
 (3) at any time during the continuance of any such failure, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent;
and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 
  

 48 

 Subject to applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent,
or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Senior Note of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due
and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Senior Note 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 of general circulation in New York City 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.

written statement, which need not comply with Section 102, signed by the principal executive officer, the principal financial officer or the principal accounting officer of the Company, as to his or her knowledge of the Company’s
compliance with all conditions and covenants under this Indenture and if a default or an Event of Default has occurred, specify such default or Event of Default and the nature and status thereof, of which such signer may have knowledge. For purposes
of this Section 1005, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. 
 Section 1006. Waiver of Certain Covenants. 
 The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 1004 or Section 1007 with respect to the Senior Notes of any series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Senior Notes
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.

replaced; or 
 (2) attachment, judgment or other similar liens arising in connection with court proceedings, provided that
the execution or other enforcement of such liens is effectively stayed and (i) the claims secured thereby are being actively contested in good faith by appropriate proceedings or (ii) payment of the claims is covered in full (subject to

written notice thereof to the Trustee, and the Company will prior to or simultaneously with such pledge, mortgage, hypothecation or grant of security interest, by supplemental indenture executed to the Trustee (or to the extent legally necessary to
another trustee or an additional or separate trustee), in form satisfactory to the Trustee, effectively secure (for so long as such other Indebtedness shall be so secured) all the Outstanding Senior Notes equally and ratably with such Indebtedness
and with any other indebtedness for money borrowed similarly entitled to be equally and ratably secured. 
 (b) Except as otherwise specified
as contemplated by Section 301 for Senior Notes of any series, the provisions of Subsection (a) of this Section 1007 shall not apply to the extent that the Company creates any Restricted Liens to secure Indebtedness that, together
with all other Indebtedness secured by Restricted Liens, does not at the time exceed 10% of Consolidated Net Tangible Assets as determined by the Company as of a month end not more than 90 days prior to the closing or consummation of the proposed

bond, note, debenture or similar instrument, or (C) for payment obligations arising under any conditional sale or other title retention arrangement (including a purchase money obligation) given in connection with the acquisition of any
businesses, properties or assets of any kind, or (D) for the payment of money relating to a capitalized lease obligation; (ii) any liability of others described in the preceding clause (i) that such Person has guaranteed or that is

terms and the provisions of Section 305. 
 If any Senior Note called for redemption shall not be so paid upon surrender thereof for

 Any Senior Note that is to be redeemed only in part shall be surrendered at an
office or agency of the Company 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, as directed by the Company, the Trustee shall authenticate and deliver to the Holder of such Senior Note without service charge, a new Senior Note of the same series, Stated
Maturity and original issue date 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 Senior Note so surrendered.

FUNDS 
 Section 1201. Applicability of Article. 
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Senior Notes of a series except as otherwise specified as contemplated by Section 301 for Senior Notes of such series.

“mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Senior Notes of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms
of Senior Notes of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Senior Notes of any series as provided for by
the terms of Senior Notes of such series.

 Section 1202. Satisfaction of Sinking Fund Payments With Senior Notes. 
 The Company (1) may deliver Outstanding Senior Notes of a series (other than any previously called for redemption), and (2) may apply as a
credit Senior Notes of a series which have been redeemed either at the election of the Company pursuant to the terms of such Senior Notes or through the application of permitted optional sinking fund payments pursuant to the terms of such Senior
Notes, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Senior Notes of such series required to be made pursuant to the terms of such Senior Notes as provided for by the terms of such series; provided
that such Senior Notes have not been previously so credited. Such Senior Notes shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Senior Notes for redemption through operation of the sinking fund
and the amount of such sinking fund payment shall be reduced accordingly. 
 Section 1203. Redemption of Senior Notes for Sinking Fund. 
 Not less than 60 days prior to each sinking fund payment date for any series of Senior Notes, the Company will deliver to the Trustee an Officer’s
Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Senior Notes of that series pursuant to Section 1202 and stating the basis for such credit and that such Senior Notes have not previously been so credited and will also deliver to the Trustee any Senior
Notes to be so delivered. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Senior Notes 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 Senior Notes shall be made upon the terms and in the manner
stated in Sections 1106 and 1107. 
 ARTICLE THIRTEEN 
 MISCELLANEOUS PROVISIONS

 An incorporator or any past, present or future director, officer, employee or stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Senior Notes or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Senior Note, each Holder shall waive and release all such liability. Such
waiver and release shall be part of the consideration for the issue of the Senior Notes.

to the benefit of the Company, the Trustee, the Holders, any Security Registrar, Paying Agent, and Authenticating Agent and their respective successors and assigns.

for the Trustee to satisfy the requirements of the USA PATRIOT Act.

Master Trust Tax Opinion and an Issuing Entity Tax Opinion. 
 Section 2.03 Interest Payment. 

 (a) For each Interest Payment Date, the amount of interest due with respect to the Class

 (a) The Issuing Entity hereby agrees that for so long as any Class A(2009-8) Notes are Outstanding, there shall
at all times be an agent appointed to calculate LIBOR for each Interest Period (the “Calculation Agent”). The Issuing Entity hereby initially appoints the Indenture Trustee as the Calculation Agent for purposes of determining LIBOR for
each Interest Period. The Calculation Agent may be removed by the Issuing Entity at any time. If the Calculation Agent is unable or unwilling to act as such or is removed by the Issuing Entity, or if the Calculation Agent fails to determine LIBOR
for an Interest Period, the Issuing Entity shall promptly appoint a replacement Calculation Agent that does not control or is not controlled by or under common control with the Issuing Entity or its Affiliates. The Calculation Agent may not resign
its duties, and the Issuing Entity may not remove the Calculation Agent, without a successor having been duly appointed. 
 (b)
On each LIBOR Determination Date, the Calculation Agent shall determine LIBOR on the basis of the rate for deposits in United States dollars for a one-month period which appears on Reuters Screen LIBOR01 Page or on such comparable system as is
customarily used to quote LIBOR as of 11:00 a.m., London time, on such date. If such rate does not appear on Reuters Screen LIBOR01 Page or on a comparable system as is customarily used to quote LIBOR the rate for that LIBOR Determination Date shall
be determined on the basis of the rates at which deposits in United States dollars are offered by the Reference Banks at approximately 11:00 a.m.,

 
London time, on that day to prime banks in the London interbank market for a one-month period. The Calculation Agent shall request the principal London office of each of the Reference Banks to
provide a quotation of its rate. If at least two such quotations are provided, the rate for that LIBOR Determination Date shall be the arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the rate for that LIBOR
Determination Date will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the Beneficiary, at approximately 11:00 a.m., New York City time, on that day for loans in United States dollars to leading European
banks for a one-month period. 
 (c) The Note Interest Rate applicable to the then current and the immediately preceding
Interest Periods may be obtained by telephoning the Indenture Trustee at its corporate trust office at (612) 667-8058 or such other telephone number as shall be designated by the Indenture Trustee for such purpose by prior written notice by the
Indenture Trustee to each Noteholder from time to time.

send to the Indenture Trustee and the Beneficiary, via email or by facsimile transmission, notification of LIBOR for the following Interest Period. 
 Section 2.05 Payments of Interest and Principal. 
 (a) Any installment of
interest or principal payable on any Class A(2009-8) Note which is punctually paid or duly provided for by the Issuing Entity and the Indenture Trustee on the applicable Interest Payment Date or Principal Payment Date shall be paid by the Paying
Agent to the Person in whose name such Class A(2009-8) Note (or one or more Predecessor Notes) is registered on the Record Date, by wire transfer of immediately available funds to such Person’s account as has been designated by written
instructions received by the Paying Agent from such Person not later than the close of business on the third Business Day preceding the date of payment or, if no such account has been so designated, by check mailed first-class, postage prepaid to
such Person’s address as it appears on the Note Register on such Record Date, except that with respect to Notes registered on the Record Date in the name of the nominee of Cede & Co., payment shall be made by wire transfer in
immediately available funds to the account designated by such nominee. 
 (b) The right of the Class A(2009-8) Noteholders to
receive payments from the Issuing Entity will terminate on the first Business Day following the Class A(2009-8) Termination Date. 
 Section 2.06 Form of Delivery of Class A(2009-8) Notes; Depository; Denominations. 

 (a) The Class A(2009-8) Notes shall be delivered in the form of a global Registered Note as
provided in Sections 2.02 and 3.01(i) of the Indenture, respectively.

 Section 2.07 Delivery and Payment for the Class A(2009-8) Notes. 
 The Issuing Entity shall execute and deliver the Class A(2009-8) Notes to the Indenture Trustee for authentication, and the Indenture
Trustee shall deliver the Class A(2009-8) Notes when authenticated, each in accordance with Section 3.03 of the Indenture. 
 Section 2.08 Supplemental Indenture. 
 The Issuing Entity may enter into a supplemental indenture with respect
to the Class A(2009-8) Notes as provided in Section 9.01 of the Indenture; provided, however, that any supplemental indenture which provides for an additional or alternative form of credit enhancement for the Class A(2009-8) Notes shall, in
addition to the requirements set forth in Section 9.01 of the Indenture, require confirmation from the Note Rating Agencies that have rated any Outstanding Notes of the CHASEseries that such change in credit enhancement will not result in a
Ratings Effect with respect to any Outstanding Notes of the CHASEseries.
