THE SECURITIES 
 Section 2.1.
Issuable in Series. 
 The aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is
unlimited. The Securities may be issued in one or more Series. All Securities of a Series shall be identical except as may be set forth in a Board Resolution, a supplemental indenture or an Officers’ Certificate detailing the adoption of the
terms thereof pursuant to the authority granted under a Board Resolution. In the case of Securities of a Series to be issued from time to time, the Board Resolution, Officers’ Certificate or supplemental indenture may provide for the method by
which specified terms (such as interest rate, Stated Maturity, record date or date from which interest shall accrue) are to be determined. Securities may differ between Series in respect of any matters, provided that all Series of Securities
shall be equally and ratably entitled to the benefits of the Indenture. 
 Section 2.2. Establishment of Terms of Series of Securities. 

At or prior to the issuance of any Securities within a Series, the following shall be established (as to the Series generally, in the case of
Subsection 2.2(1) and either as to such Securities within the Series or as to the Series generally in the case of Subsections 2.2(2) through 2.2(24)) by a Board Resolution, a supplemental indenture or an Officers’ Certificate, in each case,
pursuant to authority granted under a Board Resolution: 
 (1) the title of the Series (which shall distinguish the
Securities of that particular Series from the Securities of any other Series); 
 (2) any limit upon the aggregate principal
amount of the Securities of the Series which may be authenticated and delivered under this Indenture (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of the
Series pursuant to Section 2.7, 2.8, 2.11, 3.6 or 8.5); 
 (3) the price or prices (expressed as a percentage of the
principal amount thereof) at which the Securities of the Series will be issued; 
 (4) the date or dates on which the
principal of the Securities of the Series is payable; 
 (5) the rate or rates (which may be fixed or variable) per annum or,
if applicable, the method used to determine such rate or rates (including, but not limited to, any commodity, commodity index, stock exchange index or financial index) at which the Securities of the Series shall bear interest, if any, the date or
dates from which such interest, if any, shall accrue, the date or dates on which such interest, if any, shall commence and be payable and any regular record date for the interest payable on any Interest Payment Date; 

  
 -6- 








 (6) the place or places where the principal of and interest and premium, if any,
on the Securities of the Series shall be payable, or the method of such payment, if by wire transfer, mail or other means; 

(7) if applicable, the period or periods within which, the price or prices at which and the terms and conditions upon which the
Securities of the Series may be redeemed, in whole or in part, at the option of the Company; 
 (8) the obligation, if any,
of the Company to redeem or purchase the Securities of the Series pursuant to any sinking fund or analogous provisions or at the option of a Holder thereof and the period or periods within which, the price or prices at which and the terms and
conditions upon which Securities of the Series shall be redeemed or purchased, in whole or in part, pursuant to such obligation; 

(9) the dates, if any, on which and the price or prices at which the Securities of the Series will be repurchased by the
Company at the option of the Holders thereof and other detailed terms and provisions of such repurchase obligations; 
 (10)
if other than denominations of $2,000 and integral multiples of $1,000 in excess thereof, the denominations in which the Securities of the Series shall be issuable; 

(11) whether the Securities of the Series are to be issued in bearer (if to be issued outside of the United States) or fully
registered form (and, if in fully registered form, whether the Securities will be issuable as Global Securities); 
 (12) if
other than the principal amount thereof, the portion of the principal amount of the Securities of the Series that shall be payable upon declaration of acceleration of the Maturity thereof pursuant to Section 6.2; 

(13) the currency of denomination of the Securities of the Series, which may be Dollars or any Foreign Currency, and if such
currency of denomination is a composite currency, the agency or organization, if any, responsible for overseeing such composite currency; 

(14) the designation of the currency, currencies or currency units in which payment of the principal of and interest and
premium, if any, on the Securities of the Series will be made; 
 (15) if payments of principal of or interest or premium, if
any, on the Securities of the Series are to be made in one or more currencies or currency units other than that or those in which such Securities are denominated, the manner in which the exchange rate with respect to such payments will be
determined; 
 (16) the manner in which the amounts of payment of principal of or interest and premium, if any, on the
Securities of the Series will be determined, if such amounts may be determined by reference to an index based on a currency or currencies or by reference to a commodity, commodity index, stock exchange index or financial index; 

(17) the provisions, if any, relating to any collateral provided for the Securities of the Series; 

(18) any addition to, deletion of or change in the covenants set forth in Articles 4 or 5 that applies to Securities of the
Series; 

  
 -7- 








 (19) any addition to, deletion of or change in the Events of Default which
applies to any Securities of the Series and any change in the right of the Trustee or the requisite Holders of such Securities to declare the principal amount thereof due and payable pursuant to Section 6.2; 

(20) the terms and conditions, if any, for conversion of the Securities into or exchange of the Securities for shares of common
stock or preferred stock of the Company that apply to Securities of the Series; 
 (21) any depositories, interest rate
calculation agents, exchange rate calculation agents or other agents with respect to Securities of such Series if other than those appointed herein; 

(22) the terms and conditions, if any, upon which the Securities shall be subordinated in right of payment to other
Indebtedness of the Company; 
 (23) if applicable, that the Securities of the Series, in whole or any specified part, shall
be defeasible pursuant to Article 9; and 
 (24) any other terms of the Securities of the Series (which terms shall not be
inconsistent with the provisions of this Indenture, except as permitted by Section 8.1, but which may modify or delete any provision of this Indenture insofar as it applies to such Series), including any terms that may be required under
applicable law or regulations or advisable in connection with the marketing of Securities of that Series. 
 All Securities of any one
Series need not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board Resolution, supplemental indenture or Officers’ Certificate referred to
above, and the authorized principal amount of any Series may not be increased to provide for issuances of additional Securities of such Series, unless otherwise provided in such Board Resolution, supplemental indenture or Officers’ Certificate.

 Section 2.3. Execution and Authentication. 

The Securities shall be executed on behalf of the Company by two Officers of the Company or an Officer and an Assistant Secretary of the
Company. Each such signature may be either manual or facsimile. The Company’s seal may be impressed, affixed, imprinted or reproduced on the Securities and may be in facsimile form. 

If an Officer whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall
nevertheless be valid. 
 A Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating
agent. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. The Trustee shall at any time, and from time to time, authenticate Securities for original issue in the principal amount provided in the
Board Resolution, supplemental indenture hereto or Officers’ Certificate, upon receipt by the Trustee of a Company Order. Such Company Order may authorize authentication and delivery pursuant to oral or electronic instructions from the Company
or its duly authorized agent or agents, which oral instructions shall be promptly confirmed in writing. Each Security shall be dated the date of its authentication. 

The aggregate principal amount of Securities of any Series outstanding at any time may not exceed any limit upon the maximum principal amount
for such Series set forth in the Board Resolution, supplemental indenture hereto or Officers’ Certificate delivered pursuant to Section 2.2, except as provided in Section 2.8. 

  
 -8- 








 Prior to the issuance of Securities of any Series, the Trustee shall have received and (subject
to Section 7.2) shall be fully protected in relying on: (a) the Board Resolution, supplemental indenture hereto or Officers’ Certificate establishing the form of the Securities of that Series or of Securities within that Series and
the terms of the Securities of that Series or of Securities within that Series, (b) an Officers’ Certificate complying with Section 10.4, and (c) an Opinion of Counsel complying with Section 10.4. 

The Trustee shall have the right to decline to authenticate and deliver any Securities of such Series: (a) if the Trustee, being advised
in writing by outside counsel, determines that such action may not lawfully be taken; or (b) if the Trustee in good faith by its board of directors or trustees, executive committee or a trust committee of directors and/or vice-presidents shall
reasonably determine that such action would expose the Trustee to personal liability, or cause it to have a conflict of interest with respect to Holders of any then outstanding Series of Securities. 

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate
Securities whenever the Trustee may do so. Any appointment shall be evidenced by instrument signed by an authorized officer of the Trustee, a copy of which shall be furnished to the Company. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or an Affiliate of the Company. 

Section 2.4. Registrar and Paying Agent. 

The Company shall maintain in each Place of Payment for any Series of Securities (i) an office or agency where such Securities may be
presented for registration of transfer or for exchange (“Registrar”), (ii) an office or agency where such Securities may be presented for payment (“Paying Agent”) provided that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the register for the Securities maintained by the Registrar, and (iii) an office or agency where notices and demands to or upon
the Company in respect of such Securities and this Indenture may be served (“Service Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars and one
or more additional paying agents. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee as set forth in Section 10.2. If the Company acts as Paying Agent, it shall segregate the
money held by it for the payment of principal of and premium, if any, and interest on the Securities and hold it as a separate trust fund. The Company may change any Paying Agent, Registrar or co-registrar without notice to any Securityholder. In
acting hereunder and in connection with the Securities, the Paying Agent and Registrar shall act solely as agents of the Company, and will not thereby assume any obligations towards or relationship of agency or trust for or with any Holder. 

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

The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement
shall implement the provisions of this Indenture that 

  
 -9- 








 
relate to such Agent. The Company shall notify the Trustee of the name and address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, or agent for service of notices
and demands, or fails to give the foregoing notice, the Trustee shall act as such. The Company hereby appoints the Trustee as the initial Registrar, Paying Agent and Service Agent for each Series unless another Registrar, Paying Agent or Service
Agent, as the case may be, is appointed prior to the time Securities of that Series are first issued. The Company hereby initially designates the Corporate Trust Office of the Trustee as such office of the Company. 

Section 2.5. Paying Agent to Hold Assets in Trust. 

Not later than 11:00 a.m., New York City time, on each due date of any principal of or premium or interest on any Securities, the Company shall
deposit with the Paying Agent money in immediately available funds sufficient to pay such principal, premium, if any, or interest. The Trustee as Paying Agent shall, and the Company shall require each Paying Agent other than the Trustee to agree in
writing that each Paying Agent shall hold in trust for the benefit of the Holders of any Series of Securities or the Trustee all assets held by the Paying Agent for the payment of principal of, or interest or premium (if any) on, such Series of
Securities (whether such assets have been distributed to it by the Company or any other obligor on such Series of Securities), and the Company and the Paying Agent shall notify the Trustee in writing of any Default by the Company (or any other
obligor on such Series of Securities) in making any such payment; provided, however, that to the extent any such funds are received by the Paying Agent from the Company after 11:00 a.m., New York time, on such due date, such funds will be
distributed to such Persons within one Business Day of receipt thereof. The Company at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during
the continuance of any payment default with respect to any Series of Securities, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon
distribution to the Trustee of all assets that shall have been delivered by the Company to the Paying Agent, the Paying Agent shall have no further liability for such assets. 

Section 2.6. Securityholder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
Securityholders of each Series of Securities. If the Trustee is not the Registrar, the Company shall furnish to the Trustee as of each regular record date for the payment of interest on the Securities of a Series and before each related Interest
Payment Date, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders of each Series of Securities. 

Section 2.7. Transfer and Exchange. 

When Securities of a Series are presented to the Registrar with a request to register the transfer thereof, the Registrar shall register the
transfer as requested if the requirements of applicable law are met, and when such Securities of a Series are presented to the Registrar with a request to exchange them for an equal principal amount of other authorized denominations of Securities of
the same Series, the Registrar shall make the exchange as requested. To permit transfers and exchanges, upon surrender of any Security for registration of transfer at the office or agency maintained pursuant to Section 2.4 hereof, the Company
shall execute and the Trustee shall authenticate Securities at the Registrar’s request. 
 If Securities are issued as Global
Securities, the provisions of Section 2.15 shall apply. 
 All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 

  
 -10- 








 Every Security presented or surrendered for registration of transfer or for exchange shall (if so
required by the Company or the Registrar or a co-Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar or a co-Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing. 
 Any exchange or transfer shall be without charge, except that the Company may require payment by the
Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation to a transfer or exchange, but this provision shall not apply to any exchange pursuant to Section 2.11, 3.6 or 8.5 hereof. The Trustee
shall not be required to register transfers of Securities of any Series or to exchange Securities of any Series for a period of 15 days before the record date for selection for redemption of such Securities. The Trustee shall not be required to
exchange or register transfers of Securities of any Series called or being called for redemption in whole or in part, except the unredeemed portion of such Security being redeemed in part. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among the Depositary or other beneficial owners of interests in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with
the express requirements hereof. Neither the Trustee, or any of it respective agents, shall have responsibility for any actions taken or not taken by a Depositary.

The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in, the
applicable Depositary or other Person with respect to the accuracy of the records of a Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any
participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption or purchase) or the payment of any amount or delivery of any Securities (or other security or property) under or with
respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Securities shall be given or made only to or upon the order of the registered Holders (which shall be
the Depositary or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the applicable Depositary subject to the applicable rules and procedures of the
Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the applicable Depositary with respect to its members, participants and any beneficial owners. 

Section 2.8. Replacement Securities. 

If a mutilated Security is surrendered to the Trustee or if the Holder of a Security presents evidence to the satisfaction of the Company and
the Trustee that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security of the same Series and of like tenor and principal amount and bearing a number not
contemporaneously outstanding. An indemnity bond may be required by the Company or the Trustee that is sufficient in the reasonable judgment of the Company or the Trustee, as the case may be, to protect the Company, the Trustee or any Agent from any
loss which any of them may suffer if a Security is replaced. The Company may charge such Holder for its out-of-pocket expenses in replacing a Security, including the fees and expenses of the Trustee. Upon the issuance of any new Security under this
Section, the Company or the Trustee 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 and its
counsel) connected therewith. Every replacement Security shall constitute an original additional obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all other Securities of that Series duly issued hereunder. 
 Section 2.9.
Outstanding Securities. 
 Securities outstanding at any time are all Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation, and those described in this Section 2.9 as not outstanding. 
 If a Security is
replaced pursuant to Section 2.8 (other than a mutilated Security surrendered for replacement), it ceases to be outstanding until the Company and the Trustee receive proof satisfactory to each of them that the replaced Security is held by a
bona fide purchaser. A mutilated Security ceases to be outstanding upon surrender of such Security and replacement thereof pursuant to Section 2.8. 

If a Paying Agent holds on a Redemption Date or the Stated Maturity money sufficient to pay the principal of, premium, if any, and accrued
interest on Securities payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture (provided that, if such Securities are to be redeemed, notice of such redemption has been
duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made), then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue. 

The Company may purchase or otherwise acquire the Securities, whether by open market purchases, negotiated transactions or otherwise. A
Security does not cease to be outstanding solely because the Company or an Affiliate holds the Security. 

  
 -11- 








 Section 2.10. When Treasury Securities Disregarded; Determination of Holders’ Action. 

In determining whether the Holders of the required aggregate principal amount of the Securities of any Series have concurred in any direction,
waiver or consent, the Securities of any Series owned by the Company or any other obligor on such Securities or by any Affiliate of any of them shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected
in relying on any such direction, waiver or consent, only Securities of such Series which the Trustee actually knows are so owned shall be so disregarded. Securities of such Series so owned which have been pledged in good faith shall not be
disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities of such Series and that the pledgee is not the Company or any other obligor upon the Securities of such
Series or any Affiliate of any of them. 
 Section 2.11. Temporary Securities. 

Until definitive Securities are ready for delivery, the Company may prepare and execute and the Trustee shall authenticate temporary
Securities. Temporary Securities shall be substantially in the form, and shall carry all rights, of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare and execute and the Trustee shall authenticate definitive Securities in exchange for temporary Securities presented to it without charge to the Holder. Until so exchanged, temporary Securities shall have the same rights under
this Indenture as the definitive Securities. 
 Section 2.12. Cancellation. 

All Securities 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 for cancellation. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold. The
Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel and
at the written request of the Company, shall dispose of all Securities surrendered for transfer, exchange, payment, replacement or cancellation. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption
or satisfaction of the Indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.12. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section 2.12, except as expressly permitted by this Indenture. 
 Section 2.13. Payment of Interest;
Defaulted Interest; Computation of Interest. 
 Except as otherwise provided as contemplated by Section 2.2 with respect to any
Series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security is registered at the close of business on the regular
record date for such interest, as provided in the Board Resolution, supplemental indenture hereto or Officers’ Certificate establishing the terms of such Series. 

If the Company defaults in a payment of interest on the Securities, it shall pay the defaulted amounts, plus, to the extent permitted by law,
any interest payable on defaulted amounts pursuant to Section 4.1 hereof, to the Persons who are Securityholders on a subsequent special record date, which 

  
 -12- 








 
date shall be the fifteenth day, whether or not a Business Day, next preceding the date fixed by the Company for the payment of defaulted interest. At least 15 days before the special record
date, the Company shall mail or cause to be mailed to each Securityholder, with a copy to the Trustee, a notice that states the special record date, the payment date, and the amount of defaulted interest, and interest payable on such defaulted
interest, if any, to be paid. 
 Except as otherwise specified as contemplated by Section 2.2 for Securities of any Series, interest on
the Securities of each Series shall be computed on the basis of a 360-day year of twelve 30-day months. 
 Section 2.14. CUSIP Number. 

The Company in issuing the Securities may use one or more “CUSIP” numbers, and if so, the Trustee shall use the CUSIP number(s) in
notices of redemption or exchange as a convenience to Holders, provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number(s) printed in the notice or on the Securities, and
that reliance may be placed only on the other identification numbers printed on the Securities and any such redemption shall not be affected by any defect in or omission of any such numbers. 

Section 2.15. Provisions for Global Securities. 

(a) A Board Resolution, a supplemental indenture hereto or an Officers’ Certificate shall establish whether the Securities of a Series
shall be issued in whole or in part in the form of one or more Global Securities and the Depositary for such Global Securities or Securities. 

(b) Notwithstanding any provisions to the contrary contained in Section 2.7 of the Indenture and in addition thereto, if, and only if
(A) the Depositary at any time is unwilling or unable to continue as Depositary for such Global Security or ceases to be a clearing agency registered under the Exchange Act and a successor Depositary is not appointed by the Company within 90
days after the date the Company is so informed in writing or becomes aware of the same, (B) an Event of Default occurs with respect to the Securities or (C) the Company shall so elect, the Company promptly will execute and deliver to the
Trustee definitive Securities, and the Trustee, upon receipt of a Company Request for the authentication and delivery of such definitive Securities (which the Company will promptly execute and deliver to the Trustee) and an Officers’
Certificate to the effect that such Global Security shall be so exchangeable, will authenticate and deliver definitive Securities, without charge, registered in such names and in such authorized denominations as the Depositary shall direct in
writing (pursuant to instructions from its direct and indirect participants or otherwise) in an aggregate principal amount equal to the principal amount of the Global Security with like tenor and terms. Upon the exchange of a Global Security for
definitive Securities, such Global Security shall be canceled by the Trustee. Unless and until it is exchanged in whole or in part for definitive Securities, as provided in this Section 2.15(b), a Global Security may not be transferred except
as a whole by the Depositary with respect to such Global Security to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such a successor Depositary. 
 (c) Any Global Security issued hereunder shall bear a legend in substantially the
following form: 
 “THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN
THE NAME OF THE DEPOSITARY OR A NOMINEE OF THE DEPOSITARY. THIS 

  
 -13- 








 
SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND MAY NOT BE
TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY, BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF
SUCH A SUCCESSOR DEPOSITARY.” 
 In addition, so long as the Depository Trust Company (“DTC”) is the Depositary, each Global
Security registered in the name of DTC or its nominee shall bear a legend in substantially the following form: 
 “UNLESS THIS GLOBAL
SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY GLOBAL SECURITY ISSUED IS
REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.” 

(d) The Depositary, as a Holder, may appoint agents and otherwise authorize participants to give or take any request, demand, authorization,
direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the Indenture. 
 (e) Notwithstanding the
other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.2, payment of the principal of and interest and premium, if any, on any Global Security shall be made to the Depositary or its nominee in its capacity
as the Holder thereof. 
 (f) Except as provided in Section 2.15(e), the Company, the Trustee and any Agent shall treat a Person as the
Holder of such principal amount of outstanding Securities of any Series represented by a Global Security as shall be specified in a written statement of the Depositary (which may be in the form of a participants’ list for such Series) with
respect to such Global Security, for purposes of obtaining any consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture, provided that until the Trustee is so provided with a written
statement, it may treat the Depositary or any other Person in whose name a Global Security is registered as the owner of such Global Security for the purpose of receiving payment of principal of and any premium and, any interest on such Global
Security and for all other purposes whatsoever, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 

Section 2.16. Persons Deemed Owners. 

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, the Registrar and any agent of the Company, the
Registrar or the Trustee shall treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and any interest on such Security and for all other purposes
whatsoever, and neither the Company, the Trustee, the Registrar nor any agent of the Company, the Registrar or the Trustee shall be affected by notice to the contrary.

 ARTICLE 3  

REDEMPTION 
 Section 3.1. Notices
to Trustee. 
 The provisions of this Article shall be applicable to the Securities of any Series which are redeemable prior to their
Stated Maturity except as otherwise specified as contemplated by Section 2.2 for Securities of such Series. The Company may, with respect to the Securities of any such Series, reserve the right to redeem and pay the Series of Securities or may
covenant to redeem and pay the Series of Securities or any part thereof prior to the Stated Maturity thereof at such time and on such terms as provided for in such Securities or the related Board Resolution, supplemental indenture or Officers’
Certificate. If a Series of Securities is redeemable and the Company elects to redeem such Securities of a Series, it shall notify the Trustee of the Redemption Date and the principal amount of Securities to be redeemed at least 35 days (unless a
shorter notice period shall be satisfactory to the Trustee) before the Redemption Date. Any such notice may be canceled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect. 

Section 3.2. Selection by Trustee of Securities to be Redeemed. 

Unless otherwise indicated for a particular Series of Securities by a Board Resolution, a supplemental indenture or an Officers’
Certificate, if fewer than all of the Securities of a Series are to be redeemed, DTC (as such term is defined below) in accordance with its standard procedures shall select the Securities to be redeemed. If fewer than all of the Securities of a
Series are to be redeemed, the Securities of that Series to be redeemed will be selected by DTC (as such term is defined below) in accordance with its standard procedures. If the Securities to be redeemed are not Global Securities then held by DTC,
or DTC prescribes no method of selection, the Trustee will select the Securities to be redeemed on a pro rata basis, by lot, or by any other method the Trustee deems fair and appropriate and subject to and otherwise in accordance with the procedures
of DTC. 
 The Trustee shall make the selection from Securities of a Series outstanding and not previously called for redemption and shall
promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed at least 30 but not more than 60 days before the
Redemption Date. Securities of a Series in denominations of $1,000 may be redeemed only in whole. The Trustee may select for redemption portions of the principal of Securities of a Series that have denominations larger than $1,000. Securities of a
Series and portions of them it selects shall be in amounts of $1,000 or, with respect to Securities of any Series issuable in other denominations pursuant to Section 2.2(10), the minimum principal denomination for each Series and integral
multiples thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. 

Section 3.3. Notice of Redemption. 

Unless otherwise indicated for a particular Series by Board Resolution, a supplemental indenture hereto or an Officers’ Certificate, at
least 30 days, and no more than 60 days, before a Redemption Date, the Company shall mail or cause to be mailed (or shall send the applicable notice electronically, in accordance with the procedures of the Depositary), a notice of redemption to each
Holder whose Securities are to be redeemed at his or her last address as the same appears on the registry books maintained by the Registrar. The notice shall identify the Securities to be redeemed (including the CUSIP number(s) thereof, if any) and
shall state: 
 (1) the Redemption Date; 

  
 -15- 








 (2) the redemption price, and that such redemption price shall become due and
payable on the Redemption Date; 
 (3) if any Security of a Series is being redeemed in part, the portion of the principal
amount of such Security of a Series to be redeemed and that, after the Redemption Date and upon surrender of such Security of a Series, a new Security or Securities in principal amount equal to the unredeemed portion will be issued; 

(4) the name and address of the Paying Agent; 

(5) that Securities of a Series called for redemption must be surrendered to the Paying Agent to collect the redemption price,
and the place or places where each such Security is to be surrendered for such payment; 
 (6) that, unless the Company
defaults in making the redemption payment, interest on the Securities of a Series called for redemption ceases to accrue on the Redemption Date, and the only remaining right of the Holders of such Securities is to receive payment of the redemption
price upon surrender to the Paying Agent of the Securities redeemed; 
 (7) if fewer than all the Securities of a Series are
to be redeemed, the identification of the particular Securities of a Series (or portion thereof) to be redeemed, as well as the aggregate principal amount of Securities of a Series to be redeemed and the aggregate principal amount of Securities of a
Series to be outstanding after such partial redemption; 
 (8) the CUSIP number, if any, printed on the Securities being
redeemed; and 
 (9) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in
such notice or printed on the Securities. 
 At the Company’s request, upon receipt of a Company Order, the Trustee shall give the
notice of redemption in the Company’s name and at the Company’s sole expense. 
 Section 3.4. Effect of Notice of Redemption. 

Once the notice of redemption is sent as provided in Section 3.3, Securities of a Series called for redemption become due and payable on
the Redemption Date and at the redemption price, plus interest, if any, accrued to the Redemption Date. Upon surrender to the Trustee or Paying Agent, such Securities of a Series shall be paid at the redemption price, plus accrued interest, if any,
to the Redemption Date, provided that if the Redemption Date is after a regular interest payment record date and on or prior to the next Interest Payment Date, the accrued interest shall be payable to the Holder of the redeemed Securities
registered on the relevant record date, as specified by the Company in the notice to the Trustee pursuant to Section 3.1 hereof. 

  
 -16- 








 Section 3.5. Deposit of Redemption Price. 

On or prior to the Redemption Date (but no later than 11:00 A.M. Eastern Time on such date), the Company shall deposit with the Paying Agent
money sufficient to pay the redemption price of and accrued interest, if any, on all Securities to be redeemed on that date other than Securities or portions thereof called for redemption on that date which have been delivered by the Company to the
Trustee for cancellation. 
 On and after any Redemption Date, if money sufficient to pay the redemption price of and accrued interest on
Securities called for redemption shall have been made available in accordance with the preceding paragraph and the Company and the Paying Agent are not prohibited from paying such moneys to Holders, the Securities called for redemption will cease to
accrue interest and the only right of the Holders of such Securities will be to receive payment of the redemption price of and, subject to the proviso in Section 3.4, accrued and unpaid interest on such Securities to the Redemption Date. If any
Security called for redemption shall not be so paid, interest will be paid, from the Redemption Date until such redemption payment is made, on the unpaid principal of the Security and any interest or premium (if any) not paid on such unpaid
principal, in each case, unless otherwise specified with respect to the Securities of such Series as contemplated by Section 2.2, at the rate of interest borne by such Security. 

Section 3.6. Securities Redeemed in Part. 

Upon surrender of a Security of a Series that is redeemed in part, the Company shall execute and, upon receipt of a Company Order, the Trustee
shall authenticate for a Holder, at the Company’s expense, a new Security of the same Series equal in principal amount to the unredeemed portion of the Security surrendered.

the following events, unless in the establishing Board Resolution, supplemental indenture or Officers’ Certificate, it is provided that such Series shall not have the benefit of said Event of Default: 

(1) there is a default in the payment of any principal of, or premium, if any, on the Securities of such Series when the same
becomes due and payable, whether at Maturity, or upon acceleration, redemption, or otherwise; 
 (2) there is a default in
the payment of any interest on any Security of such Series when the same becomes due and payable and the Default continues for a period of 30 days (unless the entire amount of such payment is deposited by the Company with the Trustee or with a
Paying Agent prior to the expiration of such period of 30 days); 
 (3) the Company defaults in the performance of or
breaches any other covenant or agreement of the Company in the Indenture applicable to such Series and such default or breach continues for a period of 90 consecutive days after written notice thereof has been given to the Company by the Trustee or
to the Company and the Trustee by the Holders of not less than 25% in aggregate principal amount of the outstanding Securities of such Series a written notice specifying such default or breach and requiring it to be remedied and stating that such
notice is a “Notice of Default” hereunder; 
 (4) the Company or any Significant Subsidiary pursuant to or within

 (6) any
other Event of Default provided with respect to Securities of that Series, which is specified in a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate, in accordance with Section 2.2(19). 

The term “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. The term
“Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 
 When a Default is
cured, it ceases to exist. 
 Section 6.2. Acceleration. 

If an Event of Default with respect to Securities of any Series at the time outstanding (other than an Event of Default arising under
Section 6.1(4) or (5) with respect to the Company) occurs and is continuing, the Trustee by written notice to the Company, or the Holders of not less than 25% in aggregate principal amount of the Securities of that Series then outstanding by
written notice to the Company and the Trustee, may declare that the entire principal amount of, and premium, if any, on all the Securities of that Series then outstanding plus accrued and unpaid interest to the date of acceleration are immediately
due and payable, in which case such amounts shall become immediately due and payable; provided, however, that after such acceleration, but before a judgment or decree based on such acceleration is obtained by the Trustee, the Holders of a
majority in aggregate principal amount of the outstanding Securities of such Series may rescind and annul such acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of accelerated principal, premium,
if any, or interest that has become due solely because of the acceleration, have been cured or waived, (ii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid and (iii) the rescission would not conflict with any judgment or decree. No such rescission shall affect any subsequent Default or impair any right consequent thereto.
In case an Event of Default specified in Section 6.1(4) or (5) occurs with respect to the Company, such principal, premium, if any, and interest amount with respect to all of the Securities of that Series shall be due and payable
immediately without any declaration or other act on the part of the Trustee or the Holders of the Securities of that Series.

 Section 6.3. Remedies. 

If an Event of Default with respect to Securities of any Series at the time outstanding occurs and is continuing, the Trustee may pursue any
available remedy by proceeding at law or in equity to collect the payment of principal of, or premium, if any, and interest on the Securities of that Series or to enforce the performance of any provision of the Securities of that Series or this
Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Securities of that Series or does not produce any
of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of
Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 
 Section 6.4. Waiver of
Past Defaults and Events of Default. 
 The Holders of not less than a majority in principal amount of the outstanding Securities of any
Series may on behalf of the Holders of all the Securities of such Series waive any past Default hereunder with respect to such Series and its consequences, except a default: 

(1) in the payment of the principal of, or premium or interest on any Security of such Series, or 

(2) in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the
Holder of each outstanding Security 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 Event of Default or impair any right consequent thereon. 

Section 6.5. Control by Majority. 

Subject to Sections 6.2, 6.6, 6.7 and 8.2 hereof, the Holders of a majority in principal amount of the Securities of any Series then
outstanding may 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 by this Indenture with respect to such Series. The Trustee, however, may
refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of another Securityholder or that may involve the Trustee in personal liability (it being understood that
the Trustee shall have no duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holder); provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with
such direction. This Section 6.5 shall be in lieu of TIA Section 316(a)(1)(A), and TIA Section 316(a)(1)(A) is hereby expressly excluded from this Indenture and Section as permitted by the TIA. 

Section 6.6. Limitation on Suits. 

Subject to Section 6.7 below, a Securityholder may not institute any proceeding or pursue any remedy with respect to this Indenture or the
Securities of a Series unless:

respect to the Securities of that Series;

of such Series then outstanding make a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders
offer to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense to be incurred in compliance with such request; 

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity or
security; and 
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in aggregate principal amount of the Securities of such Series then outstanding. 
 A Securityholder may
not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. 

Section 6.7. Rights of Holders to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Security of a Series to receive payment of principal of,
and premium, if any, and interest of the Security of such Series on or after the respective due dates expressed in the Security of such Series, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute
and unconditional and shall not be impaired or affected without the consent of the Holder. 
 Section 6.8. Collection Suit by Trustee. 

If an Event of Default in payment of principal, premium or interest specified in Section 6.1(1) or (2) hereof with respect to
Securities of any Series at the time outstanding occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company (or any other obligor on the Securities of that Series) for the whole
amount of unpaid principal and premium, if any, and accrued interest remaining unpaid, together with interest on overdue principal and premium, if any, and, to the extent that payment of such interest is lawful, interest on overdue installments of
interest, in each case at the rate then borne by the Securities of that Series, and such further amounts 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, as set forth in Section 7.7. 
 Section 6.9. Trustee May File Proofs of Claim. 

The Trustee may file such proofs of claim and other papers or documents, and take other actions (including sitting on a committee of creditors)
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 the Securityholders allowed in any
judicial proceedings relative to the Company (or any other obligor upon the Securities), any of their respective creditors or any of their respective property and shall be entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same after deduction of its charges and expenses to the extent that any such charges and expenses are not paid out of the estate in any such proceedings and any custodian in any such
judicial proceeding is hereby authorized by each Securityholder 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 Securityholders, to pay to the Trustee any amount
due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof. 

  
 -23- 








 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of a Series or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim
of any Securityholder in any such proceedings. 
 Section 6.10. Priorities. 

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 

FIRST: to the Trustee for amounts due to it under Section 7.7; 

SECOND: to Holders of Securities for amounts due and unpaid on the Securities for principal, premium, if any, and interest,
ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any, and interest, respectively; and 

THIRD: to the Company. 

The Trustee may fix a record date and payment date for any payment to Holders of Securities pursuant to this Section 6.10. 

Section 6.11. Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted
by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.7 hereof or a suit by Holders of more than 10% in principal amount of the Securities of a Series then outstanding. 
 Section 6.12.
Waiver of Stay, Extension or Usury Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead (as a defense or otherwise) or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension, usury or other law which would prohibit or forgive the Company from paying all or any portion of the
principal of, premium, if any, and/or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that they
may lawfully do so) the Company 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. 
 Section 6.13. Restoration of Rights and Remedies. 

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

(5) The Trustee may consult with counsel reasonably acceptable to the Trustee, which may be counsel to the Company, and the
advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or
opinion of such counsel. 
 (6) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it
by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity against the costs, expenses and liabilities which
may be incurred therein or thereby. 
 (7) The Trustee shall not be deemed to have knowledge of any fact or matter
(including, without limitation, a Default or Event of Default) unless a Responsible Officer of the Trustee has actual knowledge of such fact or matter or unless written notice of such fact or matter is received by a Responsible Officer of the
Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities, the Company and this Indenture. 

(8) Unless otherwise expressly provided herein or in the Securities of a Series or the related Board Resolution, supplemental
indenture or Officers’ Certificate, the Trustee shall not have any responsibility with respect to reports, notices, certificates or other documents filed with it hereunder, except to make them available for inspection, at reasonable times, by
Securityholders, it being understood that delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (except as set forth in Section 4.4). 

(9) Permissive rights or powers granted to the Trustee hereunder shall not be construed to be a duty. 

(10) In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of
any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

(11) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties
hereunder. 
 (12) The Trustee may request that the Company deliver a certificate setting forth the names of individuals
and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture. 
 (13) In accordance
with Section 326 of the U.S.A. Patriot Act, to help fight the funding of terrorism and money laundering activities, the Trustee will obtain, verify, and record information that identifies individuals or entities that establish a relationship or
open an account with the Trustee. The Trustee will ask for the name, address, tax identification number or organization identification number and other information that will allow the Trustee to identify the individual or entity who is establishing
the relationship or opening the account. The Trustee may also ask for formation documents such as articles of incorporation, an offering memorandum, or other identifying documents to be provided. 

Section 7.3. Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may make loans to, accept deposits from,
perform services for or otherwise deal with the Company, or any Affiliate thereof, with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee, however, shall be subject to Sections 7.10 and
7.11 hereof. 

  
 -26- 








 Section 7.4. Trustee’s Disclaimer. 

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities (except that the Trustee represents that
it is duly authorized to execute and deliver this Indenture and authenticate the Securities and perform its obligations hereunder), it shall not be accountable for the Company’s use of the proceeds from the sale of Securities or any money paid
to the Company pursuant to the terms of this Indenture and it shall not be responsible for any statement in the Securities or any other document in connection with the sale of the Securities or pursuant to this Indenture other than its certificates
of authentication. 
 Section 7.5. Notice of Default. 

If a Default or an Event of Default occurs and is continuing with respect to the Securities of any Series and if it is known to the Trustee,
the Trustee shall mail to each Securityholder of the Securities of that Series notice of the Default or the Event of Default, as the case may be, within 90 days after it occurs or, if later, after a Responsible Officer of the Trustee has knowledge
of such Default or Event of Default (except if such Default or Event of Default has been validly cured or waived before the giving of such notice). Except in the case of a Default or an Event of Default in payment of the principal of, or premium, if
any, or interest on any Security of any Series, the Trustee may withhold the notice if and so long as the Board of Directors of the Trustee, the executive committee or any trust committee of such board and/or its Responsible Officers in good faith
determine(s) that withholding the notice is in the interests of the Securityholders of that Series. 
 Section 7.6. Reports by Trustee to
Holders. 
 If and to the extent required by the TIA, within 60 days after April 1 of each year commencing the April 1
following the date of this Indenture, the Trustee shall mail to each Securityholder a brief report dated as of such April 1 that complies with TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and 313(c). 

A copy of each report at the time of its mailing to Securityholders shall be filed with the Commission and any stock exchange on which the
Securities of that Series are listed. The Company shall promptly notify the Trustee when the Securities of any Series are listed on any stock exchange or any delisting thereof, and the Trustee shall comply with TIA Section 313(d). 

Section 7.7. Compensation and Indemnity. 

The Company shall pay to the Trustee or any predecessor Trustee from time to time reasonable compensation for its services as the Company and
the Trustee shall from time to time agree upon in writing. The Trustee’s compensation shall not be limited by any provision of law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee within 45 days after
receipt of request for all reasonable and documented out-of-pocket disbursements and expenses incurred or made by it in connection with its duties under this Indenture, including the reasonable compensation, disbursements and expenses of the
Trustee’s agents and counsel. 
 The Company shall indemnify the Trustee or any predecessor Trustee, and their respective officers,
directors, employees, representatives and agents, for, and hold it harmless against, any and all loss, liability, tax, (other than taxes based upon measured by or determined by income of Trustee), damage, claim or reasonable and documented expenses
incurred by it (except as set forth in the next paragraph) in connection with the acceptance or performance of its duties under this Indenture, including the reasonable, documented costs and expenses of one separate firm (in addition to one firm of
local counsel for any one jurisdiction) for defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 

  
 -27- 








 The Trustee shall notify the Company promptly of any claim asserted against the Trustee for which
it may seek indemnity. The failure by the Trustee to so notify the Company shall not however relieve the Company of its obligations. Notwithstanding the foregoing, the Company need not reimburse the Trustee for any expense or indemnify it against
any loss, liability, tax, damage, claim or expense incurred by the Trustee through its willful misconduct, bad faith or negligence (as finally adjudicated by a court of competent jurisdiction). To secure the payment obligations of the Company in
this Section 7.7, the Trustee shall have a lien prior to the Securities of any Series on all money or property held or collected by the Trustee except such money or property held in trust to pay principal of and interest and premium (if any) on
particular Securities of that Series. Such lien shall survive the satisfaction and discharge of this Indenture solely to the extent of any payment obligations of the Company under Section 7.7 at such time. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(4) or (5) hereof occurs, the
expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. For purposes of this Section 7.7, the term “Trustee” shall include any trustee appointed pursuant to
Article 9. 
 The provisions of this Section 7.7 shall survive the resignation or removal of the Trustee and the satisfaction,
discharge and termination of this Indenture for any reason. 
 Section 7.8. Replacement of Trustee. 

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.8. 
 The Trustee may resign with respect to the Securities of one or more
Series by so notifying the Company in writing at least 90 days in advance of such resignation. 
 The Holders of a majority in principal
amount of the outstanding Securities of any Series may remove the Trustee with respect to that Series by notifying the removed Trustee in writing and may appoint a successor Trustee with respect to that Series with the consent of the Company, which
consent shall not be unreasonably withheld. The Company may remove the Trustee with respect to that Series at its election if: 

(1) the Trustee fails to comply with, or ceases to be eligible under, Section 7.10 hereof; 

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (3) a Custodian or other public officer takes charge of the Trustee or its property; or 

(4) the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee with respect to any Series of Securities for any reason,
the Company shall promptly appoint, by Board Resolution, a successor Trustee. 
 If a successor Trustee with respect to the Securities of
one or more Series does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least a majority in principal amount of the outstanding Securities of the applicable
Series may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

  
 -28- 








 If the Trustee with respect to the Securities of one or more Series fails to comply with
Section 7.10 hereof, any Securityholder of the applicable Series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately following
such delivery, (i) the retiring Trustee with respect to one or more Series shall, subject to its rights under Section 7.7 hereof, transfer all property held by it as Trustee with respect to such Series to the successor Trustee,
(ii) the resignation or removal of the retiring Trustee shall become effective, and (iii) the successor Trustee with respect to such Series shall have all the rights, powers and duties of the Trustee under this Indenture. A successor
Trustee with respect to the Securities of one or more Series shall mail notice of its succession to each Securityholder of such Series. For the avoidance of doubt, notwithstanding the replacement of the Trustee pursuant to Section 7.8, the
Company’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee. 
 Section 7.9. Successor Trustee by
Consolidation, Merger or Conversion. 
 If the Trustee, or any Agent, consolidates with, merges or converts into, or transfers all or
substantially all of its corporate trust assets to, another corporation, subject to Section 7.10 hereof, the successor corporation without any further act shall be the successor Trustee or Agent, as the case may be. 

Section 7.10. Eligibility; Disqualification. 

This Indenture shall always have a Trustee who satisfies the requirements of TIA Sections 310(a) in every respect. The Trustee (or in the case
of a Trustee that is a Person included in a bank holding company system, the related bank holding company) shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. The
Trustee shall comply with TIA Section 310(b), including the provision in Section 310(b)(1). In addition, if the Trustee is a Person included in a bank holding company system, the Trustee, independently of such bank holding company, shall
meet the capital requirements of TIA Section 310(a)(2). If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.10, it shall resign immediately in the manner and with the effect specified
in this Article 7. 
 Section 7.11. Preferential Collection of Claims Against Company. 

The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
 Section 7.12. Paying Agents. 

The Company shall cause each Paying Agent other than the Trustee to execute and deliver to it and the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this Section 7.12: 
 (1) that it will hold all sums held by
it as agent for the payment of principal of, or premium, if any, or interest on, the Securities (whether such sums have been paid to it by the Company or by any obligor on the Securities) in trust for the benefit of Holders of the Securities or the
Trustee; 
 (2) that it will at any time during the continuance of any Event of Default, upon written request from the
Trustee, deliver to the Trustee all sums so held in trust by it together with a full accounting thereof; and 

  
 -29- 








 (3) that it will give the Trustee written notice within three (3) Business
Days after any failure of the Company (or by any obligor on the Securities) in the payment of any installment of the principal of, premium, if any, or interest on, the Securities when the same shall be due and payable. 

Section 7.13. Force Majeure. 
 In no
event shall the Trustee be responsible or liable 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 disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it
being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

ARTICLE 8 
 AMENDMENTS,
SUPPLEMENTS AND WAIVERS 
 Section 8.1. Without Consent of Holders. 

The Company, when authorized by a Board Resolution, and the Trustee may amend or supplement this Indenture or the Securities of any Series
without notice to or consent of any Holder of Securities of such Series: 
 (1) to cure any ambiguity, defect or
inconsistency, provided such amendment or supplement does not adversely affect the rights of any Securityholder; 

(2) to provide for the assumption of the Company’s obligations to the Holders of the Securities of such Series in
connection with a consolidation or merger of the Company or the sale, assignment, transfer, lease or other disposition of all or substantially all of the property and assets of the Company pursuant to Article 5; 

(3) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities
of one or more Series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; 

(4) to comply with any requirements of the Commission in order to maintain the qualification of this Indenture under the TIA;

 (5) to make any change that does not adversely affect the rights of any Holder of the Securities of such Series; 

(6) to conform the terms of the Securities or this Indenture to the description thereof contained in the prospectus pursuant to
which such Securities are offered and sold; 
 (7) to provide for certificated Securities in addition to uncertificated
Securities; or 
 (8) to provide for the issuance of and establish the form and terms and conditions of Securities of any
Series as permitted by this Indenture. 
 Upon the request of the Company, accompanied by a Board Resolution authorizing the execution of
any such supplemental indenture and upon receipt by the Trustee of the documents described in Section 8.6 hereof, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects
the Trustee’s own rights, duties or immunities under this Indenture, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

After an amendment or supplement under this Section 8.1 becomes effective, the Company shall mail to Securityholders a notice briefly
describing the amendment or supplement. Any failure of the Company to mail any such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any supplemental indenture. 

  
 -30- 








 Section 8.2. With Consent of Holders. 

(a) The Company, when authorized by a Board Resolution, and the Trustee may amend or supplement this Indenture or the Securities of any Series
with the written consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Securities of such Series affected by such amendment or supplement. However, without the consent of each Securityholder affected, an
amendment, supplement or waiver may not (but only with respect to the Securities of any Series held by a non-consenting Holder): 

(1) change the Stated Maturity of, or the principal of or premium or interest on, the Securities of such Series; 

(2) reduce any amounts due on the Securities of such Series or payable upon acceleration of the maturity of the Securities of
such Series following an Event of Default; 
 (3) adversely affect any right of repayment at the Holder’s option if such
option is applicable to the Securities of such Series in accordance with the provisions of Section 2.2(8); 
 (4) change
the place (except as otherwise permitted by the terms of this Indenture) or currency of payment on the Securities of such Series; 

(5) modify the Securities of such Series to contractually subordinate such Securities in right of payment to other Indebtedness
of the Company; 
 (6) reduce the percentage of Holders of Securities whose consent is required to modify or amend this
Indenture or the Securities of such Series in accordance with the provisions of this Article 8; 
 (7) reduce the percentage
of Holders of Securities whose consent is needed to waive compliance with certain provisions of this Indenture in accordance with the provisions of Section 4.6 or to waive certain Defaults in accordance with the provisions of Section 6.4;
and 
 (8) modify any of the provisions of this Section 8.2, Section 4.6 or Section 6.4, except to increase
any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Security affected thereby. 

(b) Upon the request of the Company, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and upon
the receipt by the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Securityholders as aforesaid and upon receipt by the Trustee of the documents described in Section 8.6 hereof, the Trustee shall join with the
Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture, in which case the Trustee may in its discretion, but shall not be obligated
to, enter into such supplemental indenture. 
 (c) It shall not be necessary for the consent of the Holders under this Section 8.2 to
approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

  
 -31- 








 (d) After an amendment or supplement under this Section 8.2 becomes effective, the Company
shall mail to Securityholders a notice briefly describing the amendment or supplement. Any failure of the Company to mail any such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any supplemental
indenture. 
 Section 8.3. Compliance with Trust Indenture Act. 

Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as then in effect. 

Section 8.4. Revocation and Effect of Consents. 

Until an amendment, supplement, waiver or other action becomes effective, a consent to it by a Holder of a Security is a continuing consent
conclusive and binding upon such Holder and every subsequent Holder of the same Security or portion thereof, and of any Security issued upon the transfer thereof or in exchange therefor or in place thereof, even if notation of the consent is not
made on any such Security. Any such Holder or subsequent Holder, however, may revoke the consent as to his Security or portion of a Security, if the Trustee receives the notice of revocation before the date the amendment, supplement, waiver or other
action becomes effective. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders
entitled to consent to any amendment, supplement, or waiver which record date shall be at least 30 days prior to the first solicitation of such consent. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were
Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date. 
 After an amendment, supplement, waiver or other action becomes effective, it shall bind every
Securityholder, unless it makes a change described in any of clauses (1) through (8) of Section 8.2(a) hereof. In that case the amendment, supplement, waiver or other action shall bind each Holder of a Security who has consented to it
and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of
principal of and interest and premium (if any) on a Security, on or after the respective due dates expressed in such Security, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such
Holder. 
 Section 8.5. Notation on or Exchange of Securities. 

If an amendment, supplement, or waiver changes the terms of a Security of any Series, the Trustee may request the Holder of such Security to
deliver it to the Trustee. In such case, the Trustee shall place an appropriate notation on such Security about the changed terms and return it to the Holder. Alternatively, the Company in exchange for such Security may issue and the Trustee, upon
receipt of a Company Order, shall authenticate a new security that reflects the changed terms. Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver. 

Section 8.6. Trustee to Sign Amendments, Etc. 

The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 8 if the amendment, supplement or waiver does
not adversely affect the rights, duties, liabilities or 

  
 -32- 








 
immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment, supplement or waiver the Trustee shall be entitled to receive and,
subject to Section 7.1 hereof, shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized and permitted by this Indenture. The Company may not
sign an amendment or supplement until the Board of Directors of the Company approves it.

them are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, (B) the Company irrevocably deposits in trust with the Trustee, as trust funds solely for the benefit of
the Holders of the Securities of such Series for that purpose, money or U.S. Government Obligations or a combination thereof sufficient (unless such funds consist solely of money in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee) without consideration of any reinvestment, to pay the principal of and interest on the Securities of such Series (other than Securities of such Series replaced
pursuant to Section 2.8) to maturity or redemption, as the case may be, and to pay all other sums payable by it under this Indenture, and (C) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel (at
the cost and expense of the Company), in each case stating that all conditions precedent provided for in this Article 9 relating to the satisfaction and discharge of the Indenture with respect to the Securities of such Series have been complied
with, then this Indenture shall, upon acknowledgment from the Trustee of such satisfaction and discharge, cease to be of further effect with respect to the Securities of such Series. 

Section 9.2. Legal Defeasance. 

Unless otherwise provided with respect to any Series pursuant to Section 2.2, the Company may at its option, by Board Resolution, be
discharged from its obligations with respect to the Securities of any Series on the date upon which the conditions set forth in Section 9.4 below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the Securities of such Series and to have satisfied all its other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company, shall, subject to Section 9.6 hereof, execute proper instruments acknowledging the same, as are delivered to it by the Company), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of outstanding Securities of such Series to receive solely from the trust funds described in Section 9.4 hereof and as more fully set forth in such
section, payments in respect of the principal of, premium, if any, and interest on the Securities of such Series when such payments are due, (B) the Company’s obligations with respect to the Securities of such Series under

(D) this Article 9. Subject to compliance with this Article 9, the Company may exercise its option under this Section 9.2 with respect to the Securities of any Series notwithstanding the prior exercise of its option under
Section 9.3 below with respect to the Securities of such Series.

Section or portion thereof, whether directly or indirectly by reason of any reference elsewhere herein to any such specified Section or portion thereof or by reason of any reference in any such specified Section or portion thereof to any other
provision herein or in any other document, but the remainder of this Indenture and the Securities of any Series shall be unaffected thereby.

 The Company shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations and Foreign Government Obligations deposited pursuant to Section 9.4 hereof or the principal, premium, if any, and interest received in respect

 -35- 








 Anything in this Article 9 to the contrary notwithstanding, but subject to payment of any of its
outstanding fees and expenses, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money, U.S. Government Obligations or Foreign Government Obligations held by it as provided in Section 9.4 hereof which,
in the opinion of a nationally-recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance. 
 Section 9.6. Reinstatement. 

If the Trustee or Paying Agent is unable to apply any money, U.S. Government Obligations or Foreign Government Obligations in accordance
with Section 9.1, 9.2, 9.3 or 9.4 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s
obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article 9 until such time as the Trustee or Paying Agent is permitted to apply all such money, U.S. Government
Obligations or Foreign Government Obligations, as the case may be, in accordance with Section 9.1, 9.2, 9.3 or 9.4 hereof; provided, however, that if the Company has made any payment of principal of, premium, if any, or accrued
interest on any Securities because of the reinstatement of their obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money, U.S. Government Obligations or Foreign Government
Obligations held by the Trustee or Paying Agent. 
 Section 9.7. Moneys Held by Paying Agent. 

In connection with the satisfaction and discharge of this Indenture, all moneys then held by any Paying Agent under the provisions of this
Indenture shall, upon demand of the Company, be paid to the Trustee, or if sufficient moneys have been deposited pursuant to Section 9.1 hereof, to the Company, and thereupon such Paying Agent shall be released from all further liability with
respect to such moneys. 
 Section 9.8. Moneys Held by Trustee. 

Any moneys deposited with the Trustee or any Paying Agent or then held by the Company in trust for the payment of the principal of, or
premium, if any, or interest on any Security that are not applied but remain unclaimed by the Holder of such Security for two years after the date upon which the principal of, or premium, if any, or interest on such Security shall have respectively
become due and payable shall be repaid to the Company upon Company Request, or if such moneys are then held by the Company in trust, such moneys shall be released from such trust; and the Holder of such Security entitled to receive such payment
shall thereafter, as an unsecured general creditor, look only to the Company for the payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money shall thereupon cease; provided, however, that
the Trustee or any such Paying Agent, before being required to make any such repayment, may, at the expense of the Company, either mail to each Securityholder affected, at the address shown in the register of the Securities maintained by the
Registrar or cause to be published once a week for two successive weeks, in a newspaper published in the English language, customarily published each Business Day and of general circulation in The City of New York, New York, a 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 mailing or publication, any unclaimed balance of such moneys then remaining will be repaid to the Company. After payment to the
Company or the release of any money held in trust by the Company, Securityholders entitled to the money must look only to the Company for payment as general creditors unless applicable abandoned property law designates another Person.

 Section 10.14.
Severability. 
 Each provision of this Indenture shall be considered separable and if for any reason any provision which is not

thereby and a Holder shall have no claim therefor against any party hereto. 
 Section 10.15. Securities in a Foreign Currency. 

Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate delivered pursuant to
Section 2.2 of this Indenture with respect to a particular Series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders of a specified percentage in aggregate principal amount of Securities of all Series
or all Series affected by a particular action at the time outstanding and, at such time, there are outstanding Securities of any Series which are denominated in a coin or currency other than Dollars, then the principal amount of Securities of such
Series which shall be deemed to be outstanding for the purpose of taking such action shall be that amount of Dollars that could be obtained for such amount at the Market Exchange Rate at such time. For purposes of this Section 10.15,
“Market Exchange Rate” shall mean the noon Dollar buying rate in New York City for cable transfers of that currency as published by the Federal Reserve Bank of New York. If such Market Exchange Rate is not available for any reason with
respect to such currency, the Trustee shall use, in its sole discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York or quotations from one or more major banks in The City of New York or in the country of
issue of the currency in question or such other quotations as the Trustee, upon consultation with the Company, shall deem appropriate. The provisions of this paragraph shall apply in determining the equivalent principal amount in respect of

be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on
the day on which final unappealable judgment is entered, unless such day is not a New York Banking Day, then, the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of
New York the Required Currency with the 

  
 -40- 








 
Judgment Currency on the New York Banking Day preceding the day on which final unappealable judgment is entered and (b) its obligations under this Indenture to make payments in the Required
Currency (i) shall not be discharged or satisfied by any tender, any recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the Required Currency, except to the extent that such
tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for
the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable, and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a Legal Holiday in The City of New York on which banking institutions are authorized or
required by law, regulation or executive order to close.
