(n) if the principal amount payable at the Stated Maturity of Securities of the Series will not be determinable as of any one
or more dates prior to such Stated Maturity, the amount that will be deemed to be such principal amount as of any such date for any purpose, including the principal amount thereof which will be due and payable upon any Maturity other than the Stated
Maturity or which will be deemed to be outstanding as of any such date (or, in any such case, the manner in which such deemed principal amount is to be determined), and if necessary, the manner of determining the equivalent thereof in Dollars; 

(o) any changes or additions to Article VIII; 

(p) if other than the principal amount thereof, the portion of the principal amount of the Securities of the Series that shall

(r) any addition to or change in the Events of Default with respect to any Securities of the Series and any change in the right
of the Trustee or the Holders of such Series of Securities to declare the principal, premium and interest, if any, on such Series of Securities due and payable pursuant to Section 6.02;

lieu of the Global Securities Legend; 
 (t) any Trustee, authenticating agent, Paying Agent, transfer agent or Registrar;

which apply to Securities of the Series; 
 (v) the terms, if any, of any Guarantee of the payment of principal, premium and

(w) the subordination, if any, of the Securities of the Series pursuant to this Indenture and any changes or additions to the
provisions of this Indenture then in effect; 
 (x) with regard to Securities of the Series that do not bear interest, the
dates for certain required reports to the Trustee; 
 (y) any U.S. Federal Income tax consequences applicable to the
Securities; and 
 (z) any other terms of Securities of the Series (which terms shall not be prohibited by the provisions of
this Indenture). 
 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 2.03. Execution and Authentication. One or more Officers of the Issuer shall sign the Securities on behalf of the Issuer by
manual or facsimile signature. The Issuer’s seal, if any, shall 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. A Security shall be dated the date of its authentication, unless otherwise provided by a Board Resolution, a supplemental indenture or
an Officers’ Certificate. 

  
 9 








 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 an Issuer Order, an Officers’ Certificate delivered in accordance with section 10.04 and an
Opinion of Counsel which shall state: 
 (1) that the terms of such Securities have been established by a supplemental
indenture or by or pursuant to a Board Resolution in accordance with Sections 2.01 and 2.02 and in conformity with the provisions of this Indenture; 

(2) that such Securities when authenticated and delivered by the Trustee and issued by the Issuer in the manner and subject to
any conditions specified in such Opinion of Counsel, will have been duly authorized, executed and delivered, and constitute valid and legally binding obligations of the Issuer, enforceable in accordance with their terms, subject to bankruptcy,
insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws relating to or affecting creditors’ rights generally and subject to general principles of equity, including concepts of materiality, reasonableness, good faith
and fair dealing, regardless of whether such enforceability is considered in a proceeding in equity or at law; and 
 (3)
that all conditions precedent in respect of the execution and delivery by the Issuer of such Securities have been complied with. 
 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 2.02, except as provided in Section 2.08. 
 The Trustee may appoint an authenticating agent
reasonably acceptable to the Issuer to authenticate the Securities. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as
any Registrar, Paying Agent or agent for service of notices and demands. 
 SECTION 2.04. Registrar and Paying Agent. The Issuer
shall maintain, with respect to each Series of Securities, at the place or places specified with respect to such Series pursuant to Section 2.02, an office or agency where Securities of such Series may be presented for registration of transfer
or for exchange (the “Registrar”) and an office or agency where Securities of such Series may be presented for payment (the “Paying Agent”). The Registrar shall keep a register with respect to each Series of Securities and of
their transfer and exchange. The Issuer may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any
co-registrars. The 

  
 10 








 
Issuer hereby appoints the Trustee as Registrar and Paying Agent for each Series of Securities unless another Registrar or Paying Agent, as the case may be, is appointed prior to the time
Securities of that Series are first issued. 
 The Issuer shall enter into an appropriate agency agreement with any Registrar or Paying
Agent not a party to this Indenture, which shall incorporate the terms of the Trust Indenture Act. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee of the name and address
of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Issuer or any of its domestically organized
Significant Subsidiaries may act as Paying Agent or Registrar. 
 The Issuer may remove any Registrar or Paying Agent upon written notice to
such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (1) acceptance of any appointment by a successor as evidenced by an appropriate agreement entered into by the
Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (2) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in
accordance with clause (1) above. The Registrar or Paying Agent may resign at any time upon written notice; provided, however, that the Trustee may resign as Registrar or Paying Agent only if the Trustee also resigns as Trustee in
accordance with Section 7.08. 
 SECTION 2.05. Paying Agent to Hold Money in Trust. The Issuer shall require each Paying Agent
other than the Trustee to agree in writing that the Paying Agent will hold in trust, for the benefit of Holders of any Series of Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or interest on the Series
of Securities, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or any of its Significant Subsidiaries) shall have no further liability for the money. If the Issuer or
any of its Significant Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of Holders of any Series of Securities all money held by it as Paying Agent. 

SECTION 2.06. Holder 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 Holders of each Series of Securities and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least ten days before
each 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 Holders of each Series of Securities. 

  
 11 








 SECTION 2.07. Transfer and Exchange. Where Securities of a Series are presented to the
Registrar or a co-registrar with a request to register a transfer or to exchange them for an equal principal amount of Securities of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for such
transactions are met. To permit registrations of transfers and exchanges, the Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange (except as otherwise
expressly permitted herein), but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable
upon exchanges pursuant to Sections 2.11, 3.06 or 9.05). 
 Neither the Issuer nor the Registrar shall be required (a) to issue,
register the transfer of, or exchange Securities of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Securities of that Series selected for redemption and
ending at the close of business on the day of such mailing or (b) to register the transfer of or exchange Securities of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities
selected, called or being called for redemption in part. 
 SECTION 2.08. Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security is surrendered to the Trustee, the Issuer shall execute and the Trustee, upon receipt of an Issuer Order, shall authenticate and deliver in exchange therefor a new Security of the same Series and of like tenor and principal amount
and bearing a number not contemporaneously outstanding. 
 If there shall be delivered to the Issuer and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Issuer or
the Trustee that such Security has been acquired by a bona fide purchaser, the Issuer shall execute and the Trustee, upon receipt of an Issuer Order, shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Issuer in its discretion
may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the Issuer may
require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Security of any Series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an
original additional contractual 

  
 12 








 
obligation of the Issuer, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that Series duly issued hereunder. 
 The provisions of this Section are exclusive and
shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 

SECTION 2.09. Outstanding Securities. The Securities outstanding at any time are all the Securities authenticated by the Trustee except
for those canceled by it, those delivered to it for cancellation, those reductions in the interest on a Global Security effected by the Trustee in accordance with the provisions hereof and those described in this Section as not outstanding. 

If a Security is replaced pursuant to Section 2.08, it ceases to be outstanding until the Trustee receives proof satisfactory to it that
the replaced Security is held by a bona fide purchaser. 
 If the Paying Agent holds at the Maturity of Securities of a Series money
sufficient to pay such Securities payable on that date, then on and after that date such Securities of the Series cease to be outstanding and interest on them ceases to accrue. 

A Security does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Security. 

In determining whether the Holders of the requisite principal amount of outstanding Securities of any Series have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, the principal amount of an Original Issue Discount Security that shall be deemed to be outstanding for such purposes shall be the amount of the principal thereof that would be due and
payable as of the date of such determination upon a declaration of acceleration of the Maturity thereof pursuant to Section 6.02. 

SECTION 2.10. Treasury Securities. In determining whether the Holders of the required principal amount of Securities of a Series have
concurred in any request, demand, authorization, direction, notice, consent or waiver, Securities of a Series owned by the Issuer shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on
any such request, demand, authorization, direction, notice, consent or waiver only Securities of a Series that the Trustee knows are so owned shall be so disregarded. 

SECTION 2.11. Temporary Securities. Until Definitive Securities are ready for delivery, the Issuer may prepare and the Trustee, upon
receipt of an Issuer Order, shall authenticate temporary Securities upon the Issuer’s Order. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Issuer considers appropriate for
temporary Securities. Without unreasonable delay, the Issuer shall prepare and the Trustee, upon receipt of an Issuer 

  
 13 








 
Order, shall authenticate Definitive Securities of the same Series and date of maturity in exchange for temporary Securities. Until so exchanged, temporary Securities shall have the same rights
under this Indenture as the Definitive Securities. 
 SECTION 2.12. Cancellation. The Issuer at any time may deliver Securities to
the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for transfer,
exchange, payment, replacement or cancellation and shall destroy such canceled Securities (subject to the record retention requirement of the Exchange Act) and deliver a certificate of such destruction to the Issuer, unless the Issuer otherwise
directs. The Issuer may not issue new Securities to replace Securities that it has paid for or delivered to the Trustee for cancellation. 

SECTION 2.13. Defaulted Interest. If the Issuer defaults in a payment of interest on a Series of Securities, it shall pay the defaulted
interest, plus, to the extent permitted by law, any interest payable on the defaulted interest, to the persons who are Holders of the Series on a subsequent special record date. The Issuer shall fix the record date and payment date. At least 30 days
before the record date, the Issuer shall mail to the Trustee and to each Holder of the Series a notice that states the record date, the payment date and the amount of interest to be paid. The Issuer may pay defaulted interest in any other lawful
manner. 
 SECTION 2.14. Global Securities. 

(a) Terms of Securities. 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 Security or Securities. 

(b) Transfer and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.07 of this Indenture and in
addition thereto, any Global Security shall be exchangeable pursuant to Section 2.07 of this Indenture for Securities registered in the names of Holders other than the Depositary for such Security or its nominee only if (i) such Depositary
notifies the Issuer that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case, the Issuer fails to
appoint a successor Depositary within 90 days of such event, (ii) the Issuer executes and delivers to the Trustee an Officers’ Certificate to the effect that such Global Security shall be so exchangeable or (iii) an Event of Default
with respect to the Securities represented by such Global Security shall have happened and be continuing. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as
the Depositary shall direct in writing in an aggregate principal amount equal to the principal amount of the Global Security with like tenor and terms. 

  
 14 








 Except as provided in this Section 2.14(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) Legend. Any Global Security issued hereunder shall bear a legend in
substantially the following form: 
 “THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS
SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION
9.05 OF THE INDENTURE, (II) THIS GLOBAL SECURITY MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.07 OF THE INDENTURE, (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.12 OF THE
INDENTURE AND (IV) THIS GLOBAL SECURITY MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER (AS DEFINED IN THE INDENTURE GOVERNING THIS SECURITY).” 

(d) Acts of Holders. 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 this Indenture. 

(e) Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.02,
payment of the principal of and interest, if any, on any Global Security shall be made to the Holder thereof. 
 (f) Consents,
Declaration and Directions. Except as provided in Section 2.14(e), the Issuer, the Trustee and any Agent shall treat a person as the Holder of such principal amount of outstanding Securities of such Series represented by a Global Security
as shall be specified in a written statement of the Depositary 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. 

SECTION 2.15. CUSIP Numbers. The Issuer in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if
so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of redemption and that reliance may be placed only on the other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such
numbers. 

  
 15 








 ARTICLE III 

Redemption 
 SECTION 3.01.
Notices to Trustee. The Issuer, with respect to any Series of Securities, may elect 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 provided for in such Series of Securities. If a Series of Securities is redeemable and the Issuer wants or is obligated to redeem prior to the Stated Maturity thereof all or part of the Series of Securities pursuant to
the terms of such Securities, it shall notify the Trustee in writing of the redemption date and the principal amount of Securities of the Series to be redeemed and the redemption price. The Issuer shall give such notice to the Trustee at least 30
days before the redemption date unless the Trustee consents to a shorter period. 
 SECTION 3.02. Selection of Securities to Be
Redeemed. Unless otherwise provided for a particular Series of Securities by a Board Resolution, a supplemental indenture or an Officers’ Certificate, if fewer than all the Securities of a particular Series are to be redeemed or purchased,
the Trustee shall select the Securities of such Series to be redeemed or purchased pro rata or by lot or by a method that complies with applicable legal and securities exchange requirements, if any, and that the Trustee in its sole discretion shall
deem to be fair and appropriate and in accordance with methods generally used at the time of selection by fiduciaries in similar circumstances. The Trustee shall make the selection at least 30 days but no more than 60 days before the redemption date
from outstanding Securities of a Series not previously called for redemption. Securities and portions thereof that the Trustee selects shall be in principal amounts of $1,000 or integral multiples of $1,000. Provisions of this Indenture that apply
to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall promptly notify the Issuer of the Securities (or portions thereof) to be redeemed. 

SECTION 3.03. Notice of Redemption. Unless otherwise provided for a particular Series of Securities by a Board Resolution, a
supplemental indenture or an Officers’ Certificate, at least 30 days but not more than 60 days before a date for redemption of Securities, the Issuer shall mail a notice of redemption by first-class mail to each Holder of Securities to be
redeemed at such Holder’s registered address. 
 The notice shall identify the Securities to be redeemed and shall state: 

(1) the redemption date; 

(2) the redemption price; 

(3) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that,
after the redemption date upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Security; 

  
 16 








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

(5) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(6) that, upon the satisfaction of any conditions to such redemption set forth in the notice of redemption, and unless the
Issuer defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the
redemption date; 
 (7) the paragraph of the Securities and/or provision of this Indenture pursuant to which the Securities
called for redemption are being redeemed; 
 (8) the CUSIP or ISIN 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 or ISIN number, if any, listed in
such notice or printed on the Securities. 
 In addition, if such redemption is subject to the satisfaction of one or more conditions
precedent, such notice shall describe each such condition and, if applicable, shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption
may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date stated in such notice, or by the redemption date as so delayed. 

At the Issuer’s request, the Trustee shall give the notice of redemption as provided to it in the Issuer’s name and at the
Issuer’s expense. In such event, the Issuer shall provide the Trustee with the information required by this Section. 
 SECTION 3.04.
Effect of Notice of Redemption. Once notice of redemption is mailed, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, subject to the satisfaction of any
conditions precedent provided in such notice. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice. 

Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 

SECTION 3.05. Deposit of Redemption Price. Prior to 11:00 a.m. (New York City time) on the redemption date, the Issuer shall deposit
with the Paying Agent (or, if the Issuer or a Subsidiary of the Issuer is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of, and accrued interest on, all Securities to be redeemed on that date,
other than Securities or portions of Securities 

  
 17 








 
called for redemption that have been delivered by the Issuer to the Trustee for cancellation. The Paying Agent shall as promptly as practicable return to the Issuer any money deposited with it by
the Issuer in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Securities to be redeemed. If such money is then held by the Issuer in trust and is not required for such purpose it shall be discharged from
such trust. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability
for the money delivered to the Trustee. 
 SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security that is redeemed
in part, the Issuer shall execute and the Trustee shall authenticate for the Holder (at the Issuer’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered. 

ARTICLE IV 
 Covenants 

SECTION 4.01. Payment of Securities. The Issuer shall promptly make all payments in respect of each Series of Securities on the dates
and in the manner provided in such Series of Securities and in this Indenture. Such payments shall be considered made on the date due if on such date the Trustee or the Paying Agent holds, in accordance with this Indenture, money sufficient to make
all payments with respect to such Securities then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. 

SECTION 4.02. SEC Reports. Unless otherwise provided for a particular Series of Securities in a Board Resolution, a supplemental
indenture or an Officers’ Certificate, notwithstanding that the Issuer may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Issuer shall provide the Trustee and Holders within the time periods
(including any extensions thereof) specified in the SEC’s rules and regulations copies of its annual report and certain information, documents and other reports that are specified in Sections 13 and 15(d) of the Exchange Act; provided that,
with respect to current reports that would be required to be filed with the SEC on Form 8-K, only such reports that would be required to be filed pursuant to Items 1.01 (Entry into a Material Definitive Agreement), 1.02 (Termination of a Material
Definitive Agreement), 1.03 (Bankruptcy or Receivership), 2.01 (Completion of Acquisition or Disposition of Assets), 2.03 (Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement), 2.04 (Triggering Events
that Accelerate or Increase a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement), 4.01 (Changes in Registrant’s Certifying Accountant), 4.02 (Non-Reliance on Previously Issued Financial Statements or a Related
Audit Report or Completed Interim Review) or 5.01 (Changes in Control of Registrant) shall be provided to the Trustee and the Holders; provided, however, that no such report shall be required to be furnished if the Issuer determines in
its good faith judgment that the event to be 

  
 18 








 
disclosed in such report is not material to the Holders or the business, assets, operations, financial position or prospects of the Issuer and its Significant Subsidiaries taken as a whole.
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 Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Issuer also shall comply with the other
provisions of Trust Indenture Act Section 314(a). 
 SECTION 4.03. Compliance Certificate. The Issuer shall deliver to the
Trustee within 120 days after the end of each Fiscal Year of the Issuer (commencing with the Fiscal Year ended December 31, 2015) an Officers’ Certificate stating that in the course of the performance by the signers of their duties as
Officers of the Issuer they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period. If they do, the certificate shall describe the Default, its status and what action the
Issuer is taking or proposes to take with respect thereto. The Issuer also shall comply with Trust Indenture Act Section 314(a)(4). 

SECTION 4.04. Further Instruments and Acts. The Issuer shall execute and deliver to the Trustee such further instruments and do such
further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 
 ARTICLE V 

Successor Companies 

SECTION 5.01. Merger and Consolidation. Unless otherwise provided for a particular Series of Securities in a Board Resolution, a
supplemental indenture or an Officers’ Certificate, the Issuer shall not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its properties and assets to, any Person unless: 

(i) the resulting, surviving or transferee Person (the “Successor Company”) shall be a corporation or limited
liability company organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Issuer) shall expressly assume, by a supplemental indenture, executed and
delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Issuer under the Securities and this Indenture; 

(ii) immediately after giving effect to such transaction no Event of Default shall have occurred and be continuing; and 

  
 19 








 (iii) the Issuer shall have delivered to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture. 

The Successor Company shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under this Indenture (as
modified or supplemented by a Board Resolution, a supplemental indenture or an Officers’ Certificate), and the predecessor Issuer, except in the case of a lease of all or substantially all of its assets, shall be released from the obligation to
pay the principal of and interest on the Securities. 
 ARTICLE VI 

Defaults And Remedies 

SECTION 6.01. Events of Default. Unless otherwise provided for a particular Series of Securities by a Board Resolution, a supplemental
indenture or an Officers’ Certificate, each of the following constitutes an “Event of Default” with respect to each Series of Securities: 

(1) the Issuer’s default in any payment of the principal amount of (or, in the case of Original Issue Discount Securities
of that Series, the portion thereby specified in the terms of such Security), or premium, if any, on any Security of that Series when such amount becomes due and payable at Stated Maturity, upon acceleration, required redemption or otherwise; 

(2) the Issuer’s failure to pay interest on any Security of that Series when such interest becomes due and payable, and
such failure continues for a period of 30 days; 
 (3) the Issuer fails to comply with Section 5.01; 

(4) the Issuer fails to comply with any of its covenants or agreements contained in the Securities of that Series or this
Indenture (other than those referred to in (1), (2), or (3) above) and such failure continues for 60 days after the notice specified below; 

(5) the Issuer or a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: 

(A) commences a voluntary case; 

(B) consents to the entry of an order for relief against it in an involuntary case; 

(C) consents to the appointment of a Custodian of it or for any substantial part of its property; or 

  
 20 








 (D) makes a general assignment for the benefit of its creditors or takes any
comparable action under any foreign laws relating to insolvency; or 
 (6) a court of competent jurisdiction enters an order
or decree under any Bankruptcy Law that: 
 (A) is for relief against the Issuer or a Significant Subsidiary in an
involuntary case; 
 (B) appoints a Custodian of the Issuer or a Significant Subsidiary or for any substantial part of its
property; or 
 (C) orders the winding up or liquidation of the Issuer or a Significant Subsidiary or any similar relief is
granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days. 
 The foregoing shall constitute Events
of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body. 
 The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal or
state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 

A Default under clause (4) above is not an Event of Default with respect to any Series of Securities until the Trustee or the Holders of
at least 25% in principal amount of the outstanding Securities of that Series notify the Issuer of the Default and the Issuer does not cure such Default within the time specified in clause (4) after receipt of such notice. Such notice must
specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” 
 The Issuer shall deliver
to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which with the giving of notice or the lapse of time would become an Event of Default under clause (4), its status
and what action the Issuer is taking or proposes to take with respect thereto. 
 SECTION 6.02. Acceleration. If an Event of Default
with respect to any Series of Securities at the time outstanding (other than an Event of Default specified in Section 6.01(5) or (6) with respect to the Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the outstanding Securities of that Series by notice to the Issuer (and to the Trustee if such notice is given by the Holders), may declare the principal amount of (or, in the case of Original Issue Discount Securities of that
Series, the portion thereby specified in the terms of such Security), premium, if any, and accrued and unpaid interest on all the Securities of that Series to be due and payable. Upon such a declaration, such amounts shall be due and payable
immediately. If an Event of Default specified in Section 6.01(5) or (6) with respect to the Issuer occurs, the principal amount of (or, in the case of Original Issue Discount Securities of that


  
 21 








 
Series, the portion thereby specified in the terms of such Security), premium, if any, and accrued and unpaid interest on all the Securities of each Series of Security shall ipso facto
become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the Securities of any Series of Securities by notice to the Trustee may rescind
an acceleration of that Series of Securities and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect to such Series of Securities have been cured or waived except
nonpayment of the principal amount of (or, in the case of Original Issue Discount Securities of that Series, the portion thereby specified in the terms of such Security), premium, if any, and accrued and unpaid interest on all Securities of that
Series that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

SECTION 6.03. Other Remedies. If an Event of Default with respect to any Series of Securities occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of the principal amount of (or, in the case of Original Issue Discount Securities of that Series, the portion thereby specified in the terms of such Security), premium, if any, and accrued and
unpaid 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 institute and maintain a suit or legal proceeding even if it does not possess any of the Securities of a Series or does not
produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default with respect to any Series of Securities 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. 

SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Securities of any Series then
outstanding may by notice to the Trustee waive an existing Default and its consequences except (i) a Default in the payment of the principal amount of (or, in the case of Original Issue Discount Securities of that Series, the portion thereby
specified in the terms of such Security), premium, if any, and accrued and unpaid interest on a Security of that Series, (ii) a Default arising from the failure to redeem or purchase any Security of that Series when required pursuant to the
terms of this Indenture or (iii) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder of that Series affected. When a Default is waived, it is deemed cured, but no such waiver
shall extend to any subsequent or other Default or impair any consequent right. 
 SECTION 6.05. Control by Majority. The Holders of
a majority in principal amount of the outstanding Securities of any Series may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee with
respect to that Series. However, the Trustee may refuse to follow any direction that conflicts with law or this 

  
 22 








 
Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other Holder of that Series or that would subject the Trustee to personal
liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 SECTION 6.06.
Limitation on Suits. Except to enforce the right to receive payment of the principal amount of (or, in the case of Original Issue Discount Securities, the portion thereby specified in the terms of such Security), premium, if any, and accrued
and unpaid interest on a Security of any Series when due, no Holder of a Security of that Series may pursue any remedy with respect to this Indenture or the Securities of that Series unless: 

(1) the Holder previously gave the Trustee written notice stating that an Event of Default with respect to that Series is
continuing; 
 (2) the Holders of at least 25% in principal amount of the outstanding Securities of that Series make a
written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders of that Series offer to the Trustee
security or indemnity satisfactory to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply
with the request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) the Holders
of a majority in principal amount of the outstanding Securities of that Series do not give the Trustee a direction inconsistent with such request during such 60-day period. 

A Holder of Securities of any Series may not use this Indenture to prejudice the rights of another Holder of that Series or to obtain a
preference or priority over another Holder of that Series. 
 SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of the principal amount of (or, in the case of Original Issue Discount Securities, the portion thereby specified in the terms of such Security), premium, if any, and
accrued and unpaid interest on the Securities held by such Holder, on or after their Maturity, or to bring suit for the enforcement of any such payment on or after their Maturity, shall not be impaired or affected without the consent of such Holder.

 SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided
for in Section 7.07 to cover the costs and expenses of collection, including the reasonable compensation, expenses disbursement and advances of the Trustee, its agents and its counsel. 

  
 23 








 SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim
and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Issuer or any of its Subsidiaries, their creditors or their property and,
unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by
each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. 
 SECTION 6.10.
Priorities. If the Trustee collects any money or property pursuant to this Article VI with respect to any Series of Securities, it shall pay out the money or property in the following order: 

FIRST: costs and expenses of collection, including all sums paid or advanced by the Trustee hereunder and the compensation, expenses and
disbursements of the Trustee, its agents and its counsel and all other amounts due to the Trustee under Section 7.07; 
 SECOND: to
Holders for amounts due and unpaid on the Securities of that Series for the principal amount of (or, in the case of Original Issue Discount Securities of that Series, the portion thereby specified in the terms of such Security), premium, if any, and
accrued and unpaid interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities of that Series for the principal amount of (or, in the case of Original Issue Discount Securities of that
Series, the portion thereby specified in the terms of such Security), premium, if any, and accrued and unpaid interest, respectively; and 

THIRD: to the Issuer. 
 The
Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section. At least 15 days before such record date, the Trustee shall mail to each Holder and the Issuer a notice that states the record date, the payment date
and amount to be paid. 
 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 and expenses, 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
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in principal amount of the Securities of any Series. 

  
 24 








 SECTION 6.12. Waiver of Stay or Extension Laws. The Issuer (to the extent it may lawfully
do so) shall not at any time insist upon, plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law, wherever enacted, now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the
Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 

  
 27 








 SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and
makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Issuer’s use of the proceeds from the Securities, it will not be responsible for the use or application of any money
received by any Paying Agent (other than itself as Paying Agent), and it shall not be responsible for any statement in this Indenture, in the Securities, or in any document executed in connection with the sale of the Securities, other than those set
forth in a Trustee’s certificate of authentication. 
 SECTION 7.05. Notice of Defaults. If a Default with respect to Securities
of any Series occurs and is continuing and if it is actually known to a Trust Officer of the Trustee, the Trustee shall mail to each Holder of that Series notice of the Default within 90 days after it occurs. Except in the case of a Default with
respect to Securities of any Series in payment of the principal amount of (or, in the case of Original Issue Discount Securities of that Series, the portion thereby specified in the terms of such Security), premium, if any, and accrued and unpaid
interest on any Security of that Series, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. 

SECTION 7.06. Reports by Trustee to Holder. As promptly as practicable after each May 15 beginning with the first
May 15 after the issuance of Securities pursuant to this Indenture, for so long as Securities remain outstanding, the Trustee shall mail to each Holder a brief report dated as of such reporting date that complies with Section 313(a) of
the Trust Indenture Act. The Trustee shall also comply with Section 313(b) of the Trust Indenture Act. 
 A copy of each report at the
time of its mailing to Holders shall be filed with the SEC and each stock exchange (if any) on which the Securities are listed. The Issuer agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any
delisting thereof. 
 SECTION 7.07. Compensation and Indemnity. The Issuer shall pay to the Trustee from time to time such
compensation for its services as the Issuer and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the
Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, costs of preparation and mailing of notices to Holders and reasonable costs of counsel retained by the Trustee in connection with
the delivery of an Opinion of Counsel or otherwise in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants

its duties hereunder, including the costs and expenses of enforcing the Indenture (including this Section 7.07) and of defending itself against any claims (whether asserted by any Holder, the Issuer or


  
 28 








 
otherwise). The Trustee shall notify the Issuer of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so
to notify the Issuer shall not relieve the Issuer of its indemnity obligations hereunder. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own
willful misconduct, gross negligence or bad faith. 
 To secure the Issuer’s payment obligations in this Section, the Trustee shall
have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay the principal of and interest and any liquidated damages on particular Securities. 

The Issuer’s payment obligations pursuant to this Section shall survive the satisfaction or discharge of this Indenture, any rejection or
termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(5) or (6) with respect to the Issuer, the
expenses are intended to constitute expenses of administration under the Bankruptcy Law. 
 SECTION 7.08. Replacement of Trustee. The
Trustee may resign at any time with respect to the Securities of any Series by so notifying the Issuer. The Holders of a majority in principal amount of the Securities of any Series may remove the Trustee and may appoint a successor Trustee with
respect to such Series of Securities. The Issuer shall remove the Trustee if: 
 (1) the Trustee fails to comply with
Section 7.10; 
 (2) the Trustee is adjudged bankrupt or insolvent; 

(3) a receiver 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, is removed by the Issuer or by the Holders of a majority in principal amount of the Securities of any Series and such
Holders do not reasonably promptly appoint a successor Trustee or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Issuer shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation
or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of that
Series of Securities. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 

  
 29 








 If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or
is removed, the retiring Trustee or the Holders of 10% in principal amount of the Securities of that Series may petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee fails to comply with Section 7.10, after written notice hereto, the Holders of at least 10% in principal amount of that
Series of Securities may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 shall
continue for the benefit of the retiring Trustee. 
 SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with,
merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor
Trustee. 
 In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so
authenticated; and if at that time any of the Securities shall not have been authenticated, any such successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the
Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Trust Indenture Act
Section 310(a). The Trustee 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 Trust Indenture Act Section 310(b);
provided, however, that there shall be excluded from the operation of Trust Indenture Act Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities
of the Issuer are outstanding if the requirements for such exclusion set forth in Trust Indenture Act Section 310(b)(1) are met. 

SECTION 7.11. Preferential Collection of Claims Against the Issuer. The Trustee shall comply with Trust Indenture Act
Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or has been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated.

SECTION 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. The Issuer may, at the option of its Board of Directors
evidenced by resolutions set forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Securities of any Series upon compliance with the conditions set forth below in
this Article VIII. 
 Unless otherwise provided for in a Board Resolution, a supplemental indenture or an Officers’ Certificate,
when (a) the Issuer has delivered to the Trustee for cancellation all Securities of a Series or (b) all outstanding Securities of a Series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are
by their terms to become due and payable within one year or are to be called for redemption within one year, and the Issuer shall have deposited with the Trustee as trust funds the entire amount sufficient to pay at maturity or upon redemption of
all outstanding Securities of the Series, and if, in either case, the Issuer shall also pay or cause to be paid all other sums payable under the Indenture by the Issuer, then the Indenture shall cease to be of further effect with respect to such
Securities of such Series. The Trustee shall acknowledge satisfaction and discharge of the Indenture on demand of the Issuer accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Issuer. 

SECTION 8.02. Legal Defeasance and Discharge. Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable
to this Section 8.02 with respect to any Series of Securities, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all
outstanding Securities of that Series on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the
entire Indebtedness represented by the outstanding Securities of that Series, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in
(a) and (b) below, and to have satisfied all its other obligations under such Securities and this Indenture with respect to such Securities of such Series (and the Trustee, on demand of and at the expense of the Issuer, shall execute
proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: 

(a) the rights of Holders of outstanding Securities of that Series to receive solely from the trust fund described in Section 8.04
hereof, and as more fully set forth in such Section, payments in respect of the principal of (or, in the case of Original Issue Discount Securities of that Series, the portion thereby specified in the terms of such Security), premium, if any, and
interest on such Securities when such payment are due; 

  
 31 








 (b) the Issuer’s obligations with respect to such Securities of that Series under Article
II; 
 (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s obligations in connection
therewith; and this Article VIII. 
 (d) Subject to compliance with this Article VIII, the Issuer may exercise its option under
this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 
 SECTION 8.03. Covenant
Defeasance. Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 with respect to any Series of Securities, the Issuer shall, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, be released from its obligations under the covenants contained in a Board Resolution, a supplemental indenture or an Officers’ Certificate with respect to the outstanding Securities of that Series on and after the date
the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Securities of that Series shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent
or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be
deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Securities of that Series, the Issuer may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event of Default with respect to such Securities under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Securities shall be
unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof with respect to any Series of Securities, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof and Sections 6.01(3) and 6.01(4) hereof shall not constitute Events of Default with respect to such Securities. 

SECTION 8.04. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Securities: 
 In order to exercise either Legal Defeasance or Covenant Defeasance with
respect to any Series of Securities:

of the Holders of that Series of Securities, cash in U.S. dollars, 

  
 32 








 
non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized independent registered public accounting firm, to
pay the principal amount of (or, in the case of Original Issue Discount Securities of that Series, the portion thereby specified in the terms of such Security), premium, if any, and interest on the outstanding Securities of that Series on the stated
date for payment thereof or on the applicable redemption date, as the case may be; 
 (2) in the case of an election under
Section 8.02 hereof, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that: 

(a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling; or 

(b) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Securities of that Series will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will
be subject to federal income tax on the same amounts, in the same manner and at the same time as would have been the case if such Legal Defeasance had not occurred; 

(3) in the case of an election under Section 8.03 hereof, the Issuer shall have delivered to the Trustee an Opinion of
Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Securities of that Series will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default or Event of Default with respect to that Series of Securities shall have occurred and be continuing either: 

(a) on the date of such deposit (other than a Default or Event of Default with respect to that Series of Securities resulting
from the borrowing of funds to be applied to such deposit); or 
 (b) insofar as Sections 6.01(5) or 6.01(6) hereof are
concerned, at any time in the period ending on the 91st day after the date of deposit; 
 (5) such Legal Defeasance or
Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Issuer or any of its Significant Subsidiaries are a party or by which the
Issuer or any of its Significant Subsidiaries are bound; 

  
 33 








 (6) the Issuer shall have delivered to the Trustee an Opinion of Counsel to the
effect that on the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; 

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the
Issuer with the intent of preferring the Holders of that Series of Securities over any other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuer or others; and 

(8) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that
all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 SECTION
8.05. Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of any outstanding Series of Securities shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such
Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities
of that Series. 
 Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from
time to time upon the request of the Issuer any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized independent registered public accounting firm expressed
in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance. 
 SECTION 8.06. Repayment to the Issuer. Any money deposited with the Trustee or any Paying
Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest on any Security and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and


  
 34 








 
payable shall be paid to the Issuer on its request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Security shall thereafter look only to the Issuer
for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying
Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), 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 notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. 

SECTION 8.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities
in accordance with Section 8.02 or 8.03 thereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s obligations
under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance
with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the
Issuer shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE IX 
 Amendments

 SECTION 9.01. Without Consent of Holders. The Issuer and the Trustee may amend this Indenture or the Securities without notice to
or consent of any Holder: 
 (1) to evidence the succession of another Person to the Issuer pursuant to Article V and the
assumption by such successor of the Issuer’s covenants, agreements and obligations in this Indenture and in the Securities; 

(2) to surrender any right or power conferred upon the Issuer by this Indenture, to add to the covenants of the Issuer such
further covenants, restrictions, conditions or provisions for the protection of the Holders of all or any Series of Securities as the Board of Directors of the Issuer shall consider to be for the protection of the Holders of such Securities, and to
make the occurrence, or the occurrence and continuance, of a default in respect of any such additional covenants, restrictions, conditions or provisions a Default or an Event of Default under this Indenture; provided, however, that
with respect to any such additional covenant, restriction, condition or provision, such amendment may provide for a period of grace after default, which may be shorter or longer than that allowed in the case of other Defaults, may provide for an
immediate enforcement upon such 

  
 35 








 
Default, may limit the remedies available to the Trustee upon such Default or may limit the right of Holders of a majority in aggregate principal amount of the Securities of any Series to waive
such default; 
 (3) to cure any ambiguity or correct or supplement any provision contained in this Indenture, in any
supplemental indenture or in any Securities that may be defective or inconsistent with any other provision contained therein; 

(4) to convey, transfer, assign, mortgage or pledge any property to or with the Trustee, or to make such other provisions in
regard to matters or questions arising under this Indenture as shall not adversely affect the interests of any Holders of Securities of any Series; 

(5) to modify or amend this Indenture in such a manner as to permit the qualification of this Indenture or any supplemental
indenture under the Trust Indenture Act as then in effect; 
 (6) to add or to change any of the provisions of this Indenture
to provide that Securities in bearer form may be registrable as to principal, to change or eliminate any restrictions on the payment of principal or premium with respect to Securities in registered form or of principal, premium or interest with
respect to Securities in bearer form, or to permit Securities in registered form to be exchanged for Securities in bearer form, so as to not adversely affect the interests of the Holders of Securities or any coupons of any Series in any material
respect or permit or facilitate the issuance of Securities of any Series in uncertificated form; 
 (7) in the case of
subordinated Securities, to make any change in the provisions of this Indenture or any supplemental indenture relating to subordination that would limit or terminate the benefits available to any holder of senior Indebtedness under such provisions
(but only if each such holder of senior Indebtedness consents to such change); 
 (8) to add Guarantees with respect to the
Securities or to secure the Securities; 
 (9) to make any change that does not adversely affect the rights of any Holder;

 (10) to add to, change, or eliminate any of the provisions of this Indenture with respect to one or more Series of
Securities, so long as any such addition, change or elimination not otherwise permitted under this Indenture shall (A) neither apply to any Security of any Series created prior to the execution of such supplemental indenture and entitled to the
benefit of such provision nor modify the rights of the Holders of any such Security with respect to the benefit of such provision or (B) become effective only when there is no such Security outstanding; 

  
 36 








 (11) to evidence and provide for the acceptance of appointment by a successor or
separate 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 this Indenture by more than one Trustee;
or 
 (12) to establish the form or terms of Securities and coupons of any Series pursuant to Article II. 

SECTION 9.02. With Consent of Holders. The Issuer and the Trustee may amend this Indenture or the Securities of any Series without
notice to any Holder but with the written consent of the Holders of at least a majority in principal amount of the Securities of each Series then outstanding (including consents obtained in connection with a tender offer or exchange for the
Securities) affected by such amendment. However, without the consent of each Holder affected, an amendment may not: 
 (1)
make any change to the percentage of principal amount of the outstanding Securities of any Series, the consent of whose Holders is required for any amendment, or the consent of whose Holders is required for any waiver (of compliance with certain
provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture; 
 (2)
reduce the principal amount of, premium, if any, or interest on, or extend the Stated Maturity or interest payment periods of any Security; 

(3) make any Security payable in money or securities other than those stated in the Security; 

(4) make any change that adversely affects such Holder’s right to require the Issuer to purchase the Securities in
accordance with the terms thereof and this Indenture; 
 (5) impair the right of any Holder to institute suit for the
enforcement of any payment with respect to the Securities; 
 (6) in the case of any subordinated Securities, or coupons
appertaining thereto, make any change in the provisions of this Indenture relating to subordination that adversely affects the rights of any Holder under such provisions; or 

(7) make any change in Section 6.04 or 6.07 or the second sentence of this Section 9.02. 

It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof. After an amendment under this Section becomes effective, the Issuer shall mail to all affected Holders a notice briefly describing such amendment. The failure to give such notice to
all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 

  
 37 








 SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture or
the Securities shall comply with the Trust Indenture Act as then in effect. 
 SECTION 9.04. Revocation and Effect of Consents and
Waivers. A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if
notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective once both (i) the requisite number of consents have been
received by the Issuer or the Trustee and (ii) such amendment or waiver has been executed by the Issuer and the Trustee. 
 The Issuer
may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record
date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 

SECTION 9.05. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the
Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in
exchange for the Security shall issue and the Trustee shall, upon receipt of an Issuer Order, authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the
validity of such amendment. 
 SECTION 9.06. Trustee to Sign Amendments. The Trustee shall sign any amendment authorized pursuant to
this Article IX if the amendment does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall receive indemnity satisfactory to it,
and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture and that such amendment is the legal, valid
and binding obligation of the Issuer enforceable against it in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03). 

  
 38 








 SECTION 9.07. Payment for Consent. Neither the Issuer nor any Affiliate of the Issuer
shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or
the Securities unless such consideration is offered to be paid to all Holders of such Series of Securities, ratably, that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or
agreement.

concurred in any direction, waiver or consent, Securities owned by the Issuer, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer shall be disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. Subject to the
foregoing, only Securities outstanding at the time shall be considered in any such determination. 
 SECTION 10.07. Rules by Trustee,

is a Legal Holiday, the record date shall not be affected.
