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, supplemental indenture or Officers’ Certificate detailing
the adoption of the terms thereof pursuant to authority granted under a Board Resolution may provide for the method by which specified terms (such as interest rate, maturity date, 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 this Indenture.

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; 
 (f) the place or places where the principal of and interest, if any, on the Securities of the Series shall be payable, where the
Securities of such Series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer in respect of the Securities of such Series and this Indenture may be served, and the method of such
payment, if by wire transfer, mail or other means;

Series shall be issuable; 
 (j) the forms of the Securities of the Series in bearer or fully registered form (and, if
in fully registered form, whether the Securities will be issuable as Global Securities); 
 (k) if other than the principal
amount thereof, the portion of the principal amount of the Securities of the Series that shall be payable upon acceleration or declaration of acceleration of the maturity thereof pursuant to Section 6.02; 
 (l) the currency of denomination of the Securities of the Series, which may be in Dollars or any Foreign Currency; 
 (m) the designation of the currency, currencies or currency units in which payment of the principal of and interest, if any, on the

 8 

 (q) any provisions relating to any security provided for the Securities of the
Series or any guarantees by any of the Issuer’s Subsidiaries (including any security to be provided by any such Subsidiary guarantor);

 (v) any addition to
or change in the provisions relating to satisfaction and discharge of Obligations under this Indenture with respect to the Securities of such Series, or in the provisions relating to legal defeasance or covenant defeasance under this Indenture with
respect to the Securities of such Series; 
 (w) any addition to or change in the provisions relating to modification of this
Indenture both with and without the consent of Holders of the Securities of such Series; 
 (x) any other terms or provisions of
the Securities of the Series (which may amend, supplement, modify or delete any provision of this Indenture insofar as it applies to such Series); and 
 (y) any registrars, paying agents, service agents, 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. 
 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 Officer of the Issuer (who
shall have been duly authorized by all requisite corporate actions) shall sign the Securities for the Issuer by manual or facsimile signature. 
 If an Officer whose signature is on a Security was an Officer at the time of such execution but 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 a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate, upon receipt by the Trustee of an Issuer Order.
Such Issuer Order may authorize authentication and delivery pursuant to oral or electronic instructions from the Issuer 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 unless otherwise provided by a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate. 
  

 9 

 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 or Officers’ Certificate delivered pursuant to Section 2.02, except as provided in Section 2.08.

 Prior to the issuance of Securities of any Series, the Trustee shall have received and (subject to Section 7.02) shall
be fully protected in relying on: (i) the Board Resolution, supplemental indenture 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, (ii) an Officers’ Certificate complying with Section 10.05, and (iii) an Opinion of Counsel complying with Section 10.05. 
 The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate Securities. Unless otherwise provided in
the 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 an Agent to deal with the Issuer and Affiliates of the Issuer. The Trustee shall have the right to decline to authenticate and deliver any Securities of such Series if the Trustee, being advised by counsel, determines that such action may
not lawfully be taken or if the Trustee in good faith by shall determine that such action would expose the Trustee to personal liability. 
 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 (a) Securities of such Series may be surrendered for registration of transfer or exchange
(“Registrar”), (b) Securities of such Series may be presented or surrendered for payment (“Paying Agent”) and (c) notices and demands to or upon the Issuer in respect of the Securities of such
Series and this Indenture may be served (“Service Agent”). The Issuer may act as Registrar or Paying Agent. The Registrar shall keep a register with respect to each Series of Securities and to their transfer and exchange.
The term “Registrar” includes any co-registrar; the term “Paying Agent” includes any additional paying agent; and the term “Service Agent” includes any additional service agent. The Issuer hereby
appoints the Trustee 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 Issuer will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar, Paying Agent or Service Agent. If at any time the Issuer shall fail to maintain any such required
Registrar, Paying Agent or Service Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Issuer
hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 The Issuer shall
enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee, in advance, 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. 
 The
Issuer may also from time to time designate one or more co-registrars, additional paying agents or additional service agents and may from time to time rescind such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Issuer of its obligations to maintain a Registrar, Paying Agent and Service Agent in each place so specified pursuant to Section 2.02 for Securities of any Series for such purposes. The Issuer will give
prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address of any such co-registrar, additional paying agent or additional service agent. 
 Section 2.05. Paying Agent to Hold Assets in Trust. 
 The Issuer shall require each Paying Agent other than the Trustee or the Issuer or any Subsidiary to agree in writing that each Paying Agent shall hold in trust for the benefit of Holders or the Trustee
all assets held by the Paying Agent for the payment of principal of, or interest on, the Securities (whether such assets have been distributed to it by the Issuer or any other obligor on the Securities), and shall notify the Trustee of any Default
by the Issuer (or any other obligor on the Securities) in making any such payment. The Issuer at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets

  

 10 

 
disbursed, and the Trustee may at any time during the continuance of any payment Default, 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 Issuer to the Paying Agent, the Paying Agent shall have no further liability for such assets. If the Issuer
or a Subsidiary of the Issuer acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the 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 the Holders of each Series of Securities and shall otherwise comply with Trust Indenture
Act § 312(a). If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least ten (10) days before each interest payment date with respect to any Series of Securities 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 the Holders of such Series of Securities, which list may be conclusively relied upon by the Trustee. 
 Section 2.07. Transfer and Exchange. 
 Subject to Section 2.14, where Securities of a Series are presented to the 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 as requested if its requirements for such transaction are met; provided, however, that the Securities surrendered for transfer or exchange shall be duly
endorsed or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or his or her attorney duly authorized in writing. To permit registrations of transfers and
exchanges, the Issuer shall execute and 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). 
 Without the prior written consent of the Issuer, the Registrar shall not be required to register the
transfer of or exchange Securities of any Series (i) during the period beginning at the opening of business fifteen (15) days before 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 (ii) selected, called or being called for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of such Securities, if any. 
 Section 2.08. Replacement Securities. 
 If a mutilated Security is surrendered to the Trustee or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall
authenticate and deliver a replacement Security of the same Series if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the
Trustee or the Issuer, such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuer and the Trustee to protect the Issuer, the Trustee or any Agent from any loss which any of them may suffer if a Security is replaced. The
Issuer and the Trustee may each charge such Holder for its reasonable out-of-pocket expenses in replacing a Security pursuant to this Section 2.08, including reasonable fees and expenses of counsel and of the Trustee. 
 Every replacement Security of any Series issued pursuant to this Section in lieu of any lost, destroyed or wrongfully taken
Security shall constitute an original additional contractual obligation of the Issuer, whether or not the lost, destroyed or wrongfully taken 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. 
 In case
any such mutilated, destroyed, lost or wrongfully taken 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. 
  

 11 

 The provisions of this Section 2.08 are exclusive and shall preclude (to the extent
lawful) all other rights and remedies with respect to the replacement or payment of lost, destroyed or wrongfully taken Securities. 
 Section
2.09. Outstanding Securities. 
 Subject to Section 2.10, the Securities outstanding at any time are all the
Securities authenticated by the Trustee except those cancelled 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. Subject to Section 2.10, a Security does not cease to be outstanding because the Issuer or any of its Affiliates holds the Security. 
 If a Security is replaced pursuant to Section 2.08 (other than a mutilated Security surrendered for replacement), it ceases to be
outstanding unless a Responsible Officer of the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 If the Paying Agent (other than the Issuer, a Subsidiary of the Issuer or an Affiliate of the Issuer) holds on the Maturity Date 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. 
 In determining whether the Holders of the requisite principal amount of outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal
amount of a 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
Date thereof pursuant to Section 6.02. 
 If the principal amount of any Security is considered paid under
Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on any redemption date or the Maturity Date the Trustee or Paying Agent (other than the Issuer or an Affiliate thereof) holds cash in Dollars or U.S. Government
Obligations, or a combination thereof, in amounts sufficient to pay all of the principal and interest due on the Securities payable on that date, then on and after that date such Securities cease to be outstanding and interest on them ceases to
accrue. 
 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 or an Affiliate of 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 of a Series are ready for delivery, the Issuer may prepare and the Trustee
shall authenticate temporary Securities upon an Issuer Order. Temporary Securities shall be substantially in the form of definitive Securities of the same Series but may have variations that the Issuer considers appropriate for temporary
Securities. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Securities of the same Series and Maturity Date in exchange for temporary Securities. Until such exchange, temporary Securities shall
be entitled to the same rights, benefits and privileges as definitive Securities of the same Series. 
  

 12 

 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 transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent (other than the Issuer or a Subsidiary), and no one else, shall cancel and, at the
written direction of the Issuer, shall dispose of all Securities surrendered for transfer, exchange, payment or cancellation in accordance with its customary procedures. Certification of the destruction of all cancelled Securities shall be delivered
to the Issuer upon request by the Issuer. Subject to Section 2.08, the Issuer may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. If the Issuer or any of its Subsidiaries 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. 
 Section 2.13. Defaulted Interest. 
 If the Issuer defaults in a payment of interest on the Securities of any Series, it shall pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, in any
lawful manner. The Issuer may pay the defaulted interest to the Persons who are the Holders of the Securities of such Series on a subsequent special record date, which date shall be the fifteenth (15th) day next preceding the date fixed by
the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least fifteen (15) days before any such subsequent special record date, the Issuer (or, upon the written request of the
Issuer, the Trustee in the name and at the expense of the Issuer) shall mail to each Holder, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest
payable on such defaulted interest, if any, to be paid. 
 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 Depository 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 Depository for such Security or its nominee only if (i) such Depository notifies the Issuer that it is unwilling or unable to continue as
Depository for such Global Security or if at any time such Depository ceases to be a clearing agency registered under the Exchange Act, and, in either case, the Issuer fails to appoint a successor Depository registered as a clearing agency under the
Exchange Act within ninety (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
Depository shall direct in writing in an aggregate amount equal to the principal amount of the Global Security with like tenor and terms. Except as provided in this Section 2.14(b), a Global Security may not be transferred except as a whole by
the Depository with respect to such Global Security to a nominee of such Depository, by a nominee of such Depository to such Depository or another nominee of such Depository or by the Depository or any such nominee to a successor Depository or a
nominee of such a successor Depository. 
 (c) Legend. 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 Depository or a nominee of the Depository. This Security is exchangeable for Securities registered in the name of a Person other than the Depository or its nominee only in the limited circumstances described in the
Indenture, and may not be transferred except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor
Depository or a nominee of such a successor Depository.” 
 (d) Acts of Holders. The Depository, 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. 
  

 13 

 (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 2.09 (last sentence), 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 Depository 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 and ISIN Numbers. 
 The Issuer in issuing the Securities may use “CUSIP” or “ISIN” numbers, and if so, the Trustee shall use the
“CUSIP” or “ISIN” numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the
“CUSIP” or “ISIN” numbers printed in the notice or on the Securities, and that reliance may be placed only on the other identification numbers printed on the Securities. The Issuer will promptly notify the Trustee of any change
in the “CUSIP” or “ISIN” numbers. 
 ARTICLE THREE 
 REDEMPTION 
 Section 3.01. Notices to Trustee. 
 The Issuer may, with respect to any Series of Securities, 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. 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 of the redemption date and the principal amount of Series of
Securities to be redeemed. The Issuer shall give the notice of redemption to the Trustee at least forty-five (45) days before the redemption date (unless a shorter notice shall be agreed to by the Trustee in writing), together with such
documentation and records as shall enable the Trustee to select the Securities to be redeemed. 
 Section 3.02. Selection of Securities to be
Redeemed. 
 Unless otherwise indicated for a particular Series by a Board Resolution, a supplemental indenture hereto
or an Officers’ Certificate, if less than all the Securities of a Series are to be redeemed, the Trustee shall select the Securities of the Series to be redeemed as follows: 
 (1) if such Securities are listed on a national securities exchange, in compliance with the requirements of the principal national
securities exchange on which such Securities are listed; or 
 (2) if such Securities are not so listed, on a pro rata basis, by
lot or by such other method as the Trustee shall deem fair and appropriate. 
 In the event of partial redemption, the Trustee
shall make the selection from Securities of the Series outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities of the Series that have denominations larger than
$1,000. Securities of the Series and portions of them it selects shall be in amounts of $1,000 or integral multiples of $1,000 or, with respect to Securities of any Series issuable in other denominations pursuant to Subsection 2.02(i), the
minimum principal denomination for each Series and integral multiples thereof. Provisions of this Indenture that apply to Securities of a Series called for redemption also apply to portions of Securities of that Series called for
redemption. 
  

 14 

 Section 3.03. Notice of Redemption. 
 Unless otherwise indicated for a particular Series by a Board Resolution, a supplemental indenture hereto or an Officers’
Certificate, at least thirty (30) days but not more than sixty (60) days before a redemption date, the Issuer shall mail, or cause to be mailed, a notice of redemption by first-class mail, postage prepaid, to each Holder whose Securities
are to be redeemed and if any Bearer Securities are outstanding, publish on one occasion a notice in an Authorized Newspaper (except that a redemption referred to in Article Eight may be more than sixty (60) days before the applicable
redemption date). At the Issuer’s request, the Trustee shall forward the notice of redemption in the Issuer’s name and at the Issuer’s expense. Each notice for redemption shall identify the Securities of the Series to be redeemed
(including the CUSIP or ISIN number, if any) and shall state: 
 (1) the date fixed for the redemption of such Securities;

 The Issuer shall pay or cause to be paid the principal of and interest on the Securities of each Series in the manner provided in such
Securities and this Indenture. An installment of principal of, or interest on, Securities shall be considered paid on the date it is due if the Trustee or the Paying Agent (other than the Issuer or an Affiliate thereof) holds on that date funds
designated for and sufficient to pay the installment. The Paying Agent shall return to the Issuer promptly, and in any event, no later than five (5) Business Days following the date of payment, any money (including accrued interest) that

material franchises; provided, however, that the Issuer shall not be required to preserve any such right or franchise if the Board of Directors of the Issuer shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Issuer and its Subsidiaries, taken as a whole, or if the failure so to preserve would not reasonably be expected to have a material adverse effect on the Issuer and its Subsidiaries, taken as a whole. 
 Section 4.04. Compliance Certificate. 
 The Issuer and each guarantor of any Series of Securities (to the extent that such guarantor is so required under the Trust Indenture Act) shall deliver to the Trustee with respect to such Series,

portion of the principal of and/or interest on such Securities or the guarantee, if any, of any such guarantor 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 permitted by applicable law) each 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 4.06. SEC Reports.

 (a) Whether or not required by the SEC’s rules and regulations, so long as any Securities of any Series are
outstanding, the Issuer will furnish to the Holders of such Securities, cause the Trustee with respect to such Securities to furnish to the Holders of such Securities, or file electronically with the SEC through the SEC’s Electronic Data
Gathering, Analysis and Retrieval System (or any successor system), within the time periods (including any extensions thereof) specified in the SEC’s rules and regulations:

on the annual financial statements by the Issuer’s independent accountants; and 
 (2) all current reports that would be

 (a) The Issuer will not, directly or indirectly, in a single transaction or a series of related transactions, (1) consolidate or merge with or into any other Person (other than a merger with an
Affiliate of the Issuer solely for the purpose of changing the Issuer’s jurisdiction of incorporation to another State of the United States or forming a direct holding company of the Issuer), or sell, lease, transfer, convey or otherwise
dispose of or assign all or substantially all of the assets of the Issuer or the Issuer and its Subsidiaries (taken as a whole) to any other Person or (2) effect a Plan of Liquidation, unless, in either case: 
 (1) either: 
  

	 	(i)	the Issuer will be the surviving or continuing corporation; or 

  

 17 

	 	(ii)	the Person formed by or surviving such consolidation or merger (if not the Issuer) or to which such sale, lease, conveyance or other disposition shall be made (or, in
the case of a Plan of Liquidation, any Person to which assets are transferred) (collectively, the “Successor”) is a corporation organized and existing under the laws of any State of the United States of America or the District of Columbia,
and the Successor expressly assumes, by a supplemental indenture hereto in form and substance satisfactory to the Trustee, all of the Obligations of the Issuer under the Securities and this Indenture; and 

 (2) immediately after giving effect to such transaction and the assumption of the obligations as set forth in clause (a)(1) above, if
applicable, and the incurrence of any Indebtedness to be incurred in connection therewith, no Default shall have occurred and be continuing. 
 (b) For purposes of the foregoing, the sale, lease, transfer, conveyance or other disposition or assignment of all or substantially all of the assets of one or more of the Issuer’s Subsidiaries, the
Equity Interests of which constitute all or substantially all of the assets of the Issuer, will be deemed to be the transfer of all or substantially all of the assets of the Issuer. 
 (c) Upon any consolidation, combination or merger of the Issuer, or any sale, lease, transfer, conveyance or other disposition or assignment
of all or substantially all of the assets of the Issuer in accordance with the foregoing, in which the Issuer is not the continuing obligor under the Securities and this Indenture, the surviving entity formed by such consolidation or into which the
Issuer is merged or the entity to which the sale, lease, transfer, conveyance, or other disposition or assignment is made will succeed to, and be substituted for, and may exercise every right and power of, the Issuer under the Securities and this
Indenture with the same effect as if such surviving entity had been named therein as the Issuer, and, except in the case of such a lease, the Issuer will be released from its Obligations under the Securities and this Indenture. 
 (d) This Section 5.01 shall not apply to (i) any sale, lease, transfer, conveyance or other disposition or assignment of assets
between or among (A) the Issuer and any of its Subsidiaries or (B) two or more Subsidiaries of the Issuer, or (ii) any merger or consolidation between the Issuer and any of its Subsidiaries or between any two Subsidiaries of the

 ARTICLE SIX 
 DEFAULT AND REMEDIES 
 Section 6.01. Events of Default. 
 “Event of Default,” wherever used herein with respect to Securities of any Series, means any one of 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) failure by the Issuer to pay interest on any of Security of that Series when it becomes due and payable and the
continuance of any such failure for thirty (30) consecutive days; 
 (2) failure by the Issuer to pay

 (3) failure to deposit any sinking fund payment, when and as due in respect of any Security of that Series; 

(4) failure by the Issuer to comply with any other agreement or covenant in this Indenture and the continuance of any
such failure for sixty (60) consecutive days after notice of such failure has been given to the Issuer by the Trustee or by the Holders of at least twenty-five percent (25%) of the aggregate principal amount of the Securities of that
Series then outstanding; 
  

 18 

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

 (i) commences a voluntary case, 
 (ii) consents to the entry of an order for relief against it in an involuntary case, 
 (iii) consents to the appointment of a Custodian of it or for all or substantially all of its assets, 
 (iv) makes a general assignment for the benefit of its creditors, or 
 (6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 
 (i) is for relief against the Issuer as debtor in an involuntary case, 
 (ii) appoints a Custodian of the Issuer or for all or substantially all of its assets, or 
 (iii) orders the liquidation of the Issuer, and the order or decree remains unstayed and in effect for ninety
(90) days; or 
 (7) 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 2.02(r). 
 Section 6.02. Acceleration. 
 If an Event of Default specified in Section 6.01(5) or
Section 6.01(6) with respect to the Issuer occurs, all outstanding Securities shall become immediately due and payable without any further action or notice. If an Event of Default (other than an Event of Default specified in
Section 6.01(5) or Section 6.01(6) with respect to the Issuer) shall have occurred and be continuing under this Indenture and the Securities of any Series, the Trustee, by notice to the Issuer, or the Holders of at least
twenty-five percent (25%) in aggregate principal amount of the Securities of such Series then outstanding by notice to the Issuer and the Trustee, may declare all amounts owing under such Securities of such Series to be due and
payable immediately. Upon such acceleration or declaration of acceleration, the aggregate principal (or, if any Securities of that Series are Discount Securities, such portion of the principal as may be specified in the terms of such
Securities) of and accrued and unpaid interest on the outstanding Securities of such Series shall immediately become due and payable; provided, however, that after such acceleration or declaration of acceleration, but before a
judgment or decree based on acceleration or declaration of acceleration, the Holders of a majority in aggregate principal amount of such outstanding Securities of such Series may rescind and annul such acceleration or declaration of
acceleration: 
 (1) if the rescission would not conflict with any judgment or decree; 
 (2) if all existing Defaults have been cured or waived (except nonpayment of principal and interest that has become due
solely because of this acceleration); 
 (3) 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; 
 (4) if the Issuer has paid to the Trustee its reasonable compensation and reimbursed the Trustee of its expenses, disbursements and advances; and 
 (5) in the event of a cure or waiver of a Default of the type set forth in Section 6.01(5) or
Section 6.01(6), the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Default has been cured or waived. 
 No such rescission shall affect any subsequent Default or impair any right consequent thereto. 
  

 19 

 Section 6.03. Other Remedies. 
 If a 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 interest on, such Securities or to enforce the performance of any provision of such Securities or this Indenture. 
 The Trustee for such Securities may maintain a proceeding even if it does not possess any of such Securities or does not produce any of them
in the proceeding. A delay or omission by the Trustee or any Holder of Securities in exercising any right or remedy accruing upon a Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Default. No remedy is
exclusive of any other remedy. All remedies are cumulative to the extent permitted by law. 
 Section 6.04. Waiver of Past Defaults.

 Holders of at least a majority in aggregate principal amount of the then outstanding Securities of any Series (which may
include consents obtained in connection with a tender offer or exchange offer of such Securities), by notice to the Trustee for such Securities, may, on behalf of all of the Holders of such Securities, waive an existing Default with respect to such
Securities and its consequences, except a Default in the payment of principal or interest on such Securities; provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Securities of any
Series may, on behalf of all of the Holders of such Securities, rescind an acceleration of such Securities and its consequences, including any related payment Default that resulted from such acceleration. When a Default is waived, it is cured
and ceases. 
 Section 6.05. Control by Majority. 
 (a) The Holders of at least a majority in aggregate 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 of such Series or exercising any trust or power conferred on it with respect to such Series. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this
Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction. 
 (b) In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification against any loss or expense caused by taking such action or following such direction. 
 Section 6.06. Limitation on Suits. 
 (a) Subject to Section 6.07,
no Holder of any Securities of any Series will have any right to institute any proceeding with respect to this Indenture or such Securities for any remedy thereunder, unless the Trustee for such Securities: 
 (1) has failed to act for a period of sixty (60) consecutive days after receiving notice of a continuing Event of
Default from such Holder and a request to act by Holders of at least twenty-five percent (25%) in aggregate principal amount of the outstanding Securities of such Series; 
 (2) has been offered indemnity satisfactory to it in its reasonable judgment; and 
 (3) has not received from the Holders of a majority in aggregate principal amount of the outstanding Securities of such
Series a direction inconsistent with such request. 
 (b) A Holder of any Securities of any Series may not use this
Indenture to prejudice the rights of another Holder of such Securities of such Series or to obtain a preference or priority over another Holder of Securities of such Series. 
  

 20 

 Section 6.07. Rights of Holders to Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of any Securities of any Series to receive payment of
principal of, and interest on, such Securities, on or after the respective due dates expressed in such Securities (including, if applicable, in connection with an offer to purchase or redeem), or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08. Collection Suit by
Trustee. 
 If a Default specified in Section 6.01(1), 6.01(2) or 6.01(3) with respect to Securities of any
Series occurs and is continuing, the Trustee for such Securities may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on such Securities for the whole amount of principal and accrued
interest and fees remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by such Securities and
such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of such Trustee, its agents and counsel. 
 Section 6.09. Trustee May File Proofs of Claim. 
 The Trustee for each Series of Securities may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of such Trustee (including any claim
for the compensation, expenses, disbursements and advances of such Trustee, its agents and counsel) and the Holders of the Securities for which it acts as trustee allowed in any judicial proceedings relating to the Issuer (or any other obligor upon
such Securities), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any monies or other property payable or deliverable on any such claims, and any Custodian in any such judicial proceeding is
hereby authorized by each Holder of such Securities to make such payments to such Trustee and, in the event that such Trustee shall consent to the making of such payments directly to such Holders, to pay to such Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of such Trustee, its agents and counsel, and any other amounts due such Trustee under this Indenture. Nothing herein contained shall be deemed to authorize such Trustee to authorize or
consent to or accept or adopt on behalf of any Holder for which it acts as trustee any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of such Holder, or to authorize such Trustee to vote in
respect of the claim of any such Holder in any such proceeding. The Trustee shall be entitled to participate as a member of any official committee of creditors in the matters as it deems necessary or advisable. 
 Section 6.10. Priorities. 
 If the Trustee for any Series of Securities collects any money or property pursuant to this Article Six, it shall pay out the money or property in the following order: 
 First: to the Trustee, its agents and attorneys for amounts due under this Indenture, including payment of all reasonable
compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders of such Securities for interest accrued on such Securities, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for interest; and 
 Third: to Holders of such Securities for principal amounts due and unpaid on such Securities, ratably, without preference or priority
of any kind, according to the amounts due and payable on such Securities for principal; and 
 Fourth: to the Issuer or,
if applicable, any guarantors with respect to such Securities, as their interests may appear, or to such other Person or Persons as a court of competent jurisdiction shall direct. 
  

 21 

 The Trustee, upon prior notice to the Issuer, 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 any Trustee for any action taken or
omitted by it as a 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 6.11 does not apply to a suit by the Trustee, a suit by
a Holder of a Security pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Securities of any Series.

 Section 7.07. Compensation and Indemnity. 
 The Issuer shall pay to the Trustee from time to time such compensation as the Issuer and the Trustee shall from time to time agree in writing for its services hereunder. 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 disbursements, expenses and advances (including reasonable fees and expenses of counsel)
incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Trustee’s negligence, bad faith or willful misconduct. Such expenses shall include the
reasonable fees and expenses of the Trustee’s agents and counsel. 
 The Issuer shall indemnify each of the Trustee or any
predecessor Trustee and its agents for, and hold them harmless against, any and all loss, damage, claims (including taxes (other than taxes based upon, measured by or determined by the income of the Trustee)), liability or expense incurred by them
arising out of or in connection with the acceptance or administration of this trust (including the reasonable costs and expenses of defending themselves against or investigating any claim or liability in connection

  

 24 

 
with the exercise or performance of any of the Trustee’s rights, powers or duties hereunder), except in each of the foregoing cases to the extent caused by any negligence, bad faith or
willful misconduct on their part. The Trustee shall notify the Issuer promptly of any claim asserted against the Trustee or any of its agents for which it may seek indemnity. The Issuer may, subject to the approval of the Trustee (which approval
shall not be unreasonably withheld), defend the claim and the Trustee shall cooperate in the defense. The Trustee and its agents subject to the claim may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such
counsel; provided, however, that the Issuer will not be required to pay such fees and expenses if, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), it assumes the Trustee’s defense and
there is no conflict of interest between the Issuer and the Trustee and its agents subject to the claim in connection with such defense as reasonably determined by the Trustee. The Issuer need not pay for any settlement made without its written
consent. The Issuer need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its negligence, bad faith or willful misconduct. 
 When the Trustee incurs expenses or renders services after a Default specified in Section 6.01(5) or
Section 6.01(6) occurs, such expenses and the compensation for such services shall be paid to the extent allowed under any Bankruptcy Law. 
 Notwithstanding any other provision in this Indenture, the foregoing provisions of this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the appointment of a successor
Trustee. 
 Section 7.08. Replacement of Trustee. 
 The Trustee may resign with respect to the Securities of one or more Series by so notifying the Issuer at least thirty (30) days prior to the date of the proposed resignation. The Holders of a
majority in principal amount of the Securities of any Series may remove the Trustee with respect to that Series by so notifying the Issuer and the Trustee and may appoint a successor Trustee. The Issuer may remove the Trustee with respect
to Securities of one or more Series if: 
 (1) the Trustee fails to comply with Section 7.10;

 (2) the Trustee is adjudged a bankrupt or an insolvent; 
 (3) a receiver or other public officer takes charge of the Trustee or its property; or 
 (4) the Trustee becomes incapable of acting. 
 If the Trustee retires, whether by resignation or removal, or if a vacancy exists in the office of Trustee for any reason, the Issuer shall
notify each Holder of such event and shall promptly appoint a successor Trustee. Within one (1) 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 Issuer. 
 A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Issuer. Immediately after that, after payment of all sums then owing to the Trustee pursuant to Section 7.07, the retiring Trustee shall transfer all property held by it as
Trustee to the successor Trustee, 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 with respect to each Series of Securities for
which it is acting as Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder of each such Series and, if any Bearer Securities are outstanding, publish such notice on one occasion in an Authorized
Newspaper. 
 If a successor Trustee with respect to the Securities of any one or more Series does not take office within
sixty (60) days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least ten percent (10%) in principal amount of the Securities of the applicable Series may petition any court of
competent jurisdiction for the appointment of a successor Trustee at the expense of the Issuer. 
  

 25 

 If the Trustee fails to comply with Section 7.10, any Holder may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding the
appointment of a successor 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, Etc. 
 If the Trustee
consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving
or transferee corporation is otherwise eligible hereunder, be the successor Trustee; provided, however, that such corporation shall be otherwise qualified and eligible under this Article Seven. 
 Section 7.10. Eligibility; Disqualification. 
 The Trustee shall at all times satisfy the requirements of Trust Indenture Act §§ 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee shall have a combined capital and surplus of at least
$50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act § 310(b); provided, however, that there shall be excluded from the operation of Trust Indenture
Act § 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 § 310(b)(1) are met. The provisions of Trust Indenture Act § 310 shall apply to the Issuer and any other obligor of the Securities. 
 Section 7.11. Preferential Collection of Claims Against the Issuer. 
 The Trustee, in its capacity as Trustee
hereunder, shall comply with Trust Indenture Act § 311(a), excluding any creditor relationship listed in Trust Indenture Act § 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act § 311(a) to
the extent indicated. 
 ARTICLE EIGHT 
 DISCHARGE OF INDENTURE; DEFEASANCE 
 Section 8.01. Termination of the Issuer’s
Obligations. 
 Except as otherwise provided in the last paragraph of this Section 8.01, this Indenture will be
discharged and will cease to be of further effect as to a Series of Securities issued hereunder, when either: 
 (a) all such Securities that have been authenticated (except lost, stolen or destroyed Securities that have been replaced or paid and Securities for whose payment money has been deposited in trust or segregated and held in trust by the
Issuer and thereafter repaid to the Issuer or discharged from this trust), have been delivered to the Trustee for cancellation, or 
 (b) (1) all such Securities that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year
and the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of such Securities cash in Dollars or U.S. Government Obligations, or a combination thereof, in amounts
sufficient (without reinvestment) to pay and discharge the entire Indebtedness (including all principal and accrued interest) on such Securities not theretofore delivered to the Trustee for cancellation to the date of maturity or redemption;

 (2) the Issuer or any guarantor of such Securities has paid or caused to be paid all other sums payable
by the Issuer under this Indenture; and 
  

 26 

 (3) the Issuer has delivered irrevocable instructions to the Trustee
for such Securities under this Indenture to apply the deposited money toward the payment of such Securities at maturity or on the date of redemption, as the case may be. 
 In addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee for such Securities stating that all conditions precedent to satisfaction and discharge have
been complied with. 
 In the case of clause (b) of this Section 8.01, and subject to the next sentence and
notwithstanding the foregoing paragraph, the Issuer’s obligations in Sections 2.06, 2.07, 2.08, 2.09, 4.01, 4.02, 4.03 (as to legal existence of the Issuer only), 7.07, 8.05 and 8.06 shall survive until such Securities are no longer outstanding
pursuant to the last paragraph of Section 2.09. In addition, nothing in this Section 8.01 shall be deemed to discharge the obligations in Section 7.07, 8.04(a), 8.05 or 8.06, all of which shall survive the satisfaction and discharge
of this Indenture. 
 After such delivery or irrevocable deposit, the Trustee upon request by the Issuer shall acknowledge in
writing the discharge of the Issuer’s obligations under such Securities and this Indenture except for the surviving obligations specified above. 
 Section 8.02. Legal Defeasance and Covenant Defeasance. 
 (a) The Issuer may at any time, at the option of
its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02(b) or 8.02(c) applied to all outstanding Securities of any Series upon compliance with the conditions
set forth below in this Article Eight. 
 (b) Upon the Issuer’s exercise under Section 8.02(a) of the option
applicable to this Section 8.02(b), the Issuer and each guarantor, if any, of such Securities will, subject to the satisfaction of the conditions set forth in Section 8.03, be deemed to have been discharged from its or their obligations
with respect to all outstanding Securities of such Series (including the related guarantees, if any) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance
means that the Issuer and such guarantors, if any, will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities of such Series (including the related guarantees, if any), which will thereafter be
deemed to be “outstanding” only for the purposes of Section 8.04 and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all its or their other obligations under such
Securities, such guarantees, if any, and this Indenture (and the Trustee for such Securities, 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: 
 (1) the rights of Holders of outstanding
Securities of such Series to receive, solely from the trust fund described in Section 8.04, and as more fully set forth in Section 8.04, payments in respect of the principal of or interest on, such Securities when such payments are
due; 
 (2) the Issuer’s obligations with respect to such Securities under Article Two and
Section 4.02 hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee for such
Securities hereunder and the Issuer’s and the guarantors’, if any, obligations in connection therewith; and 
 (4) the provisions of this Article Eight applicable to Legal Defeasance (including Sections 8.04, 8.05 and 8.06). 
 Subject to compliance with this Article Eight, the Issuer may exercise its option under this Section 8.02(b) notwithstanding the prior exercise of its option under Section 8.02(c) hereof. 
 (c) Upon the Issuer’s exercise under Section 8.02(a) hereof of the option applicable to this Section 8.02(c), the
Issuer and each of the guarantors, if any, will, subject to the satisfaction of the conditions set forth in Section 8.03 hereof, be released from each of their or its obligations under the covenants specified in a Board Resolution, a
supplemental indenture hereto or an Officers’

  

 27 

 
Certificate, in accordance with Section 2.02(v), with respect to the outstanding Securities of the applicable Series on and after the date the conditions set forth in Section 8.03
hereof are satisfied (hereinafter, “Covenant Defeasance”), and such Securities shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders of such
Securities (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 such Series, the Issuer may omit to comply with and shall have no obligation or 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 under Section 6.01, but, except as specified above, the remainder of this Indenture and such Securities will be unaffected thereby. In addition, upon the Issuer’s exercise under
Section 8.02(a) of the option applicable to this Section 8.02(c), subject to the satisfaction of the conditions set forth in Section 8.03, clause (4) of Section 6.01 shall not constitute an Event of Default. 

Section 8.03. Conditions to Legal Defeasance or Covenant Defeasance. 
 In order to exercise either Legal Defeasance under Section 8.02(b) or Covenant Defeasance under Section 8.02(c) with respect to Securities of any Series: 
 (1) the Issuer must irrevocably deposit with the Trustee for such Securities, in trust, for the benefit of the Holders
of such Securities, money or U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without reinvestment), in the opinion of a nationally recognized firm of independent public accountants selected by the Issuer,
to pay the principal of and interest on, and any mandatory sinking fund payments in respect of, the outstanding Securities of such Series on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the
Issuer must specify whether such Securities are being defeased to such stated date for payment or to a particular redemption date; 
 (2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee for such Securities an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that: 
 (i) the Issuer has received from, or there has been published by, the Internal Revenue Service, a
ruling, or 
 (ii) since the date of this Indenture, there has been a change in the applicable U.S. federal
income tax law, 
 in either case to the effect that, and based thereon, the Holders of the outstanding Securities of such Series will not
recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such
Legal Defeasance had not occurred; 
 (3) in the case of Covenant Defeasance, the Issuer shall have
delivered to the Trustee for such Securities an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of such Securities will not recognize income, gain or loss for U.S. federal income tax purposes
as a result of such Covenant Defeasance and will be subject to U.S. 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 with respect to such Securities shall have occurred and be continuing on the date of such deposit (other
than a Default resulting from the borrowing of funds to be applied to such deposit); 
  

 28 

 (5) the Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound (other than any such default resulting
solely from the borrowing of funds to be applied to such deposit and the grant of any Lien on such deposit in favor of the Trustee and/or the Holders); 
 (6) the Issuer shall have delivered to the Trustee for such Securities an Officers’ Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders of
such Securities over any other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any other of its creditors; and 
 (7) the Issuer shall have delivered to the Trustee for such Securities an Officers’ Certificate and an Opinion of Counsel, stating, in the case of the Officers’ Certificate, clauses
(1) through (6) of this Section 8.03, as applicable, have been complied with and stating, in the case of the Opinion of Counsel, that the conditions provided for in clause (2) or (3), as applicable, and clause (5) of this
Section 8.03 have been complied with. 
 Section 8.04. Application of Trust Money. 
 (a) The Trustee or Paying Agent shall hold in trust all money and U.S. Government Obligations (including the proceeds thereof) deposited
with it pursuant to this Article Eight in respect of the outstanding Securities of any Series, and shall apply the deposited money and U.S. Government Obligations (including any proceeds thereof) in accordance with this Indenture to the payment
of the principal of and the interest on such Securities. The Trustee shall be under no obligation to invest said money and U.S. Government Obligations (including any proceeds thereof), except as it may agree with the Issuer. 
 (b) The Issuer will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the money or U.S.
Government Obligations (including any proceeds thereof) deposited pursuant to Section 8.03, 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 the applicable Series. 
 (c) Anything in this Article Eight to the contrary
notwithstanding, the Trustee shall promptly deliver or pay to the Issuer from time to time upon the request of the Issuer any money or U.S. Government Obligations held by it as provided in Section 8.03 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 that would then be required to be deposited to effect an equivalent Legal Defeasance or
Covenant Defeasance. 
 Section 8.05. 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 Series of Securities and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) will
be discharged from such trust; and the Holders of such Securities will thereafter be permitted to 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, will 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 will not be less than thirty (30) days from the date of such notification or publication, any
unclaimed balance of such money then remaining will be repaid to the Issuer. 
  

 29 

 Section 8.06. Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article Eight or by
reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and any applicable guarantors’ Obligations under this Indenture and the applicable
Securities and the guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eight until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with this
Article Eight; provided, however, that if the Issuer has made any payment of interest on, or principal of, any such Securities 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 or U.S. Government Obligations held by the Trustee or Paying Agent. 
 ARTICLE NINE 
 AMENDMENTS, SUPPLEMENTS AND WAIVERS 
 Section 9.01. Without Consent of Holders. 
 Subject to Section 9.02 of
this Indenture, the Issuer and the Trustee may amend or supplement this Indenture or the Securities of one or more Series without the consent of any Holder: 
 (1) to cure any ambiguity, defect or inconsistency; 
 (2) to provide for uncertificated Securities in addition to or in place of certificated Securities; 
 (3) to provide for the assumption of the Issuer’s or a guarantor’s obligations to the Holders of the
Securities in the case of a merger, consolidation or sale of all or substantially all of the assets, in accordance with Article Five; 
 (4) to add guarantees with respect to the Securities of any Series; 
 (5) to release any guarantor from its guarantee or any of its other obligations under this Indenture (to the extent permitted by this Indenture); 
 (6) to make any change that would provide any additional rights or benefits to the Holders of Securities or that does
not adversely affect the legal rights hereunder of any Holder; 
 (7) to comply with requirements of the SEC
in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act; 
 (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; or 
 (9) 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. 
 Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the
documents described in Section 7.02(b), the Trustee will join with the Issuer in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 
  

 30 

 Section 9.02. With Consent of Holders. 
 (a) The Issuer and the Trustee may enter into a supplemental indenture hereto with the written consent of the Holders of at least a
majority in aggregate principal amount of the outstanding Securities of each Series affected by such supplemental indenture (including consents obtained in connection with a tender offer or exchange offer for the Securities of such Series), for
the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture hereto or of modifying in any manner the rights of the Holders of each such Series. Subject to
Section 6.07, the Holders of at least a majority in aggregate principal amount of the outstanding Securities of each Series by notice to the Trustee (including waivers obtained in connection with a tender offer or exchange offer for the
Securities of such Series) may waive compliance by the Issuer with any provision of this Indenture or the Securities with respect to such Series without notice to any other Holders. 
 (b) Notwithstanding Section 9.02(a), without the consent of each Holder affected, no amendment or waiver may (with respect to any
Securities held by a non-consenting Holder): 
 (1) reduce the principal or change the Stated Maturity of
any Security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation; 
 (2) reduce the rate of or extend the time for payment of interest on any Security; 
 (3) reduce the principal amount of Discount Securities payable upon acceleration of the maturity thereof; 
 (4) waive a redemption payment with respect to any Security or change any of the provisions with respect to the redemption of any Securities, except as specifically set forth in the Board Resolution,
supplemental indenture or Officers’ Certificate delivered pursuant to Section 2.02; 
 (5) make
the principal of or interest, if any, on any Security payable in money or currency other than that stated in the Security; 
 (6) if the Securities of such Holder are entitled to the benefit of any guarantee, release any guarantor of such Securities other than as provided in this Indenture or modify the guarantee in any
manner adverse to such Holder; 
 (7) waive a Default in the payment of principal of or interest on any
Security (except a rescission of acceleration of the Securities of any Series by the Holders of at least a majority in principal amount of the outstanding Securities of such Series and a waiver of the payment Default that resulted from
such acceleration); 
 (8) change the amount of Securities whose Holders must consent to an amendment,
supplement or waiver; or 
 (9) make any change in Section 6.07, this Section 9.02(b),
Section 10.14 or Section 10.15. 
 (c) It shall not be necessary for the consent of the Holders of Securities
under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 (d) A consent to any amendment, supplement or waiver under this Indenture by any Holder given in connection with an exchange (in the
case of an exchange offer) or a tender (in the case of a tender offer) of such Holder’s Securities will not be rendered invalid by such tender or exchange. 
 (e) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail, or cause to be mailed, to the Holders of Securities affected thereby and, if any
Bearer Securities affected thereby are outstanding, publish on one occasion in an Authorized Newspaper, a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail or publish such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. 
  

 31 

 Section 9.03. Compliance with the Trust Indenture Act. 
 Every amendment to this Indenture or the Securities of one or more Series shall be set forth in a supplemental indenture hereto that
complies with the Trust Indenture Act as then in effect. 
 Section 9.04. Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder
and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may
revoke the consent as to his Security or portion of a Security before the date on which the Trustee receives an Officers’ Certificate certifying that the Holders of the requisite Securities have consented (and not theretofore revoked such
consent) to the amendment, supplement or waiver. 
 The Issuer 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 thirty (30) days prior to the first solicitation of such consent. If a record date is fixed, then notwithstanding
the last sentence of 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 revoke any consent previously given, whether or not such
Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than ninety (90) days after such record date. The Issuer shall inform the Trustee in writing of the fixed record date if applicable.

 After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in
any of clauses (1) through (9) of Section 9.02(b), in which case, the amendment, supplement or waiver shall bind only each Holder of Securities who has consented to it and every subsequent Holder of a Securities or portion of
Securities that evidences the same debt as the consenting Holder’s Securities; provided, however, that no such amendment, supplement or waiver shall impair or affect the right of any Holder to receive payment of principal of, and
interest on, a Security, on or after the respective due dates therefor, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder. 
 Section 9.05. Notation on or Exchange of Securities. 
 If an amendment, supplement or waiver changes the terms of a Security, the Issuer may require the Holder of the Security to deliver it to the Trustee. The Issuer shall provide the Trustee with an
appropriate notation on the Security about the changed terms and cause the Trustee to return it to the Holder at the Issuer’s expense. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Security shall
issue, and the Trustee 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 9.06. Trustee To Sign Amendments, Etc. 
 The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine; provided, however, that the Trustee may, but shall not be obligated to, execute
any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an
Officers’ Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture and constitutes legal, valid and binding obligations of the
Issuer enforceable in accordance with its terms, subject to customary exceptions. Such Opinion of Counsel shall be at the expense of the Issuer. 
  

 32 

 Section 9.07. Trustee Protected. 
 In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Trustee shall sign all supplemental indentures hereto, except that the Trustee need not sign any supplemental indenture that adversely affects its rights.

 If the Issuer mails a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time.

 Section 10.10. No Recourse Against Others. 
 No director, officer, employee, incorporator, stockholder, member or manager of the Issuer or any Subsidiary shall have any liability for any obligations of the Issuer or any Subsidiary under the
Securities of any Series or this Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation, and no Officer shall have any personal liability for any Officers’ Certificate signed by such Officer

 Section 10.11. Successors.

 To the extent permitted by applicable law, in
case any one or more of the provisions in this Indenture or in the Securities shall be held invalid, illegal or unenforceable, in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and
of the remaining provisions shall not in any way be affected or impaired thereby, it being intended that all of the provisions hereof shall be enforceable to the full extent permitted by law. 
 Section 10.14. Securities in a Foreign Currency or in ECU. 
 Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate delivered pursuant to Section 2.02 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 (including ECUs), then the principal amount of Securities of such Series which shall be

  

 35 

 
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 10.14, “Market Exchange Rate “ shall mean the noon Dollar buying rate in New York City, New York for cable transfers of that currency as published by the Federal Reserve Bank of New York; provided,
however, in the case of ECUs, “Market Exchange Rate” shall mean the rate of exchange determined by the Commission of the European Union (or any successor thereto) as published in the Official Journal of the European Union (such
publication or any successor publication, the “Journal”). 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, in the case of ECUs, the rate of exchange as published in the Journal, as of the most recent available date, or quotations or, in the case of ECUs, rates of exchange from one or more major
banks in The City of New York, New York or in the country of issue of the currency in question or, in the case of ECUs, in Luxembourg or such other quotations or, in the case of ECUs, rates of exchange as the Trustee, upon consultation with the
Issuer, shall deem appropriate. The provisions of this paragraph shall apply in determining the equivalent principal amount in respect of Securities of a Series denominated in currency other than Dollars in connection with any action taken by
Holders of Securities pursuant to the terms of this Indenture. 
 All decisions and determinations of the Trustee regarding the
Market Exchange Rate or any alternative determination provided for in the preceding paragraph shall be in its sole discretion and shall, in the absence of manifest error, to the extent permitted by law, be conclusive for all purposes and irrevocably
binding upon the Issuer and all Holders. 
 Section 10.15. Judgment Currency. 
 The Issuer agrees, to the fullest extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining
judgment in any court it is necessary to convert the sum due in respect of the principal of or interest or other amount on the Securities of any Series (the “Required Currency”) into a currency in which a judgment will 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, 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, New York the Required Currency with the 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 the preceding clause (a) of this Section 10.15), 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, New York on which banking institutions are authorized or required by law, regulation or executive order to close. 
 ARTICLE ELEVEN 
 SINKING FUNDS 
 Section 11.01. Applicability of Article. 
 The provisions of this Article shall be applicable to any sinking fund for the retirement of the Securities of a Series, except as otherwise permitted or required by any form of Security of such
Series issued pursuant to this Indenture. 
  

 36 

 The minimum amount of any sinking fund payment provided for by the terms of the Securities
of any Series is herein referred to as a “mandatory sinking fund payment” and any other amount provided for by the terms of Securities of such Series is herein referred to as an “optional sinking fund
payment.” If provided for by the terms of Securities of any Series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 11.02. Each sinking fund payment shall be applied to the redemption of
Securities of any Series as provided for by the terms of the Securities of such Series. 
 Section 11.02. Satisfaction of Sinking Fund
Payments with Securities. 
 The Issuer may, in satisfaction of all or any part of any sinking fund payment with respect to
the Securities of any Series to be made pursuant to the terms of such Securities (1) deliver outstanding Securities of such Series to which such sinking fund payment is applicable (other than any of such Securities previously called
for mandatory sinking fund redemption) and (2) apply as credit Securities of such Series to which such sinking fund payment is applicable and which have been repurchased by the Issuer or redeemed either at the election of the Issuer
pursuant to the terms of such Series of Securities (except pursuant to any mandatory sinking fund) or through the application of permitted optional sinking fund payments or other optional redemptions pursuant to the terms of such Securities,
provided that such Securities have not been previously so credited. Such Securities shall be received by the Trustee, together with an Officers’ Certificate with respect thereto, not later than fifteen (15) days prior to the date on
which the Trustee begins the process of selecting Securities for redemption, and shall be credited for such purpose by the Trustee at the price specified in such Securities for redemption through operation of the sinking fund and the amount of such
sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities in lieu of cash payments pursuant to this Section 11.02, the principal amount of Securities of such Series to be redeemed in order to
exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such Series for redemption, except upon receipt of an Issuer Order that such action be taken, and such cash payment shall be held by the
Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall from time to time upon receipt of an Issuer Order pay over and deliver to the Issuer any
cash payment so being held by the Trustee or such Paying Agent upon delivery by the Issuer to the Trustee of Securities of that Series purchased by the Issuer having an unpaid principal amount equal to the cash payment required to be released
to the Issuer. 
 Section 11.03. Redemption of Securities for Sinking Fund. 
 Not less than forty-five (45) days (unless otherwise indicated in the Board Resolution, supplemental indenture or Officers’
Certificate in respect of a particular Series of Securities) prior to each sinking fund payment date for any Series of Securities, the Issuer will deliver to the Trustee an Officers’ Certificate specifying the amount of the next
ensuing mandatory sinking fund payment for that Series pursuant to the terms of that Series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and
crediting of Securities of that Series pursuant to Section 11.02, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and the Issuer shall thereupon be obligated to pay the amount
therein specified. 
 Not less than thirty (30) days (unless otherwise indicated in the Board Resolution, supplemental
indenture or Officers’ Certificate in respect of a particular Series of Securities) before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 3.02 and cause notice of the redemption thereof to be given in the name of and at the expense of the Issuer in the manner provided in Section 3.03. Such notice having been duly given, the redemption of such Securities
shall be made upon the terms and in the manner stated in Sections 3.04, 3.05 and 3.06.

 2.2.4 the date or dates on which the principal of the Securities of the Series is payable;

interest, if any, shall commence and be payable and any regular record date for the interest payable on any interest payment date; 
 2.2.6
the place or places where the principal of and interest, if any, on the Securities of the Series shall be payable, where the Securities of such Series may be surrendered for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of such Series and this Indenture may be served, and the method of such payment, if by wire transfer, mail or other means;

to Section 6.2; 
 2.2.15 any addition to or change in the covenants set forth in Articles IV or V which applies to Securities of the

 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 hereto 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. 
 Two
Officers shall sign the Securities for the Company by manual or facsimile signature. 
 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. 
  

 6 

 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 unless otherwise provided by a Board
Resolution, a supplemental indenture hereto or an Officers’ Certificate. 
 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. 
 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 by counsel,
determines that such action may not be taken lawfully; 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 determine that such action
would expose the Trustee to personal liability 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. 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, with respect to each Series of Securities, at the place or places
specified with respect to such Series pursuant to Section 2.2, an office or agency where Securities of such Series may be presented or surrendered for payment (“Paying Agent”), where Securities of such Series may be surrendered for
registration of transfer or exchange (“Registrar”) and where notices and demands to or upon the Company in respect of the Securities of such Series and this Indenture may be served (“Service Agent”). The Registrar shall keep a
register with respect to each Series of Securities and to their transfer and exchange. The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar, Paying Agent or
Service Agent. If at any time the Company shall fail to maintain any such required Registrar, Paying Agent or Service Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 The Company may also from time to time designate one or more co-registrars, additional paying agents or additional service agents 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 obligations to maintain a Registrar, Paying Agent and Service Agent in each place so specified pursuant to
Section 2.2 for Securities of any Series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address of any such co-registrar, additional paying
agent or additional service agent. The term “Registrar” includes any co-registrar; the term “Paying Agent” includes any additional paying agent; and the term “Service Agent” includes any additional service agent.

  

 7 

 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. 
 SECTION 2.5 Paying Agent to Hold Money in Trust. 
 The Company 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 Securityholders 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 Company 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 Company 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 Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the
Company acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of Securityholders of any Series of Securities all money held by it as Paying Agent. 
 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 and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company 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
Securityholders of each Series of Securities. 
 SECTION 2.7 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 Company 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, 3.6 or 9.6). 
 Neither the Company 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 2.8 Mutilated, Destroyed, Lost and Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefor a new Security of the same Series and of like
tenor and principal amount and bearing a number not contemporaneously outstanding. 
 If there shall be delivered to the Company and the
Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Trustee shall authenticate and make available for delivery, in lieu of any such 

  

 8 

 
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 Company
in its discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any Series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and
all other Securities of that Series duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent
lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 SECTION 2.9
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 2.8, 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 (other than the Company, a Subsidiary of the Company or an
Affiliate of the Company) holds on 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 Company or an Affiliate of the Company holds the Security. 
 In determining whether the Holders of the requisite principal amount of outstanding Securities have given any request, demand, authorization, direction,
notice, consent or waiver hereunder, the principal amount of a 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 6.2. 
 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 Company 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. 
  

 9 

 Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities upon a Company Order. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable
delay, the Company shall prepare and the Trustee upon request 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 Company 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 deliver such canceled Securities to the Company,
unless the Company otherwise directs; provided that the Trustee shall not be required to destroy Securities. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. 
 SECTION 2.13 Defaulted Interest. 
 If the
Company 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 Securityholders of the Series on a
subsequent special record date. The Company shall fix the record date and payment date. At least 10 days before the record date, the Company shall mail to the Trustee and to each Securityholder of the Series a notice that states the record date, the
payment date and the amount of interest to be paid. The Company may pay defaulted interest in any other lawful manner. 
 SECTION 2.14 Global
Securities. 
 2.14.1 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 Depository for such Global Security or Securities.

thereto, any Global Security shall be exchangeable pursuant to Section 2.7 of the Indenture for Securities registered in the names of Holders other than the Depository for such Security or its nominee only if (i) such Depository notifies
the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a clearing agency registered under the Exchange Act, and, in either case, the Company fails to appoint a
successor Depository registered as a clearing agency under the Exchange Act within 90 days of such event, (ii) the Company 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 Depository shall direct in writing in an aggregate principal amount equal to the principal amount of the Global Security with like tenor and terms. 
 Except as provided in this Section 2.14.2, a Global Security may not be transferred except as a whole by the Depository with respect to such Global
Security to a nominee of such Depository, by a nominee of such Depository to such Depository or another nominee of such Depository or by the Depository or any such nominee to a successor Depository or a nominee of such a successor Depository.

 2.14.3 Legend. Any Global Security issued hereunder shall bear a legend in substantially the following form: 
  

 10 

 “This Security is a Global Security within the meaning of the Indenture hereinafter referred to and
is registered in the name of the Depository or a nominee of the Depository. This Security is exchangeable for Securities registered in the name of a person other than the Depository or its nominee only in the limited circumstances described in the
Indenture, and may not be transferred except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor
Depository or a nominee of such a successor Depository.” 
 2.14.4 Acts Of Holders. The Depository, 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. 
 2.14.5 Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.2, payment
of the principal of and interest, if any, on any Global Security shall be made to the Holder thereof. 
 2.14.6 Consents, Declaration And
Directions. Except as provided in Section 2.14.5, the Company, 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 Depository 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 Company 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 a 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. 
 ARTICLE 3 
 REDEMPTION 
 SECTION 3.1 Notice To
Trustee. 
 The Company may, with respect to any Series of Securities, 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. If a Series of Securities is redeemable and the Company
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 of the redemption date and the principal amount of Series of
Securities to be redeemed. The Company shall give the notice at least 45 days before the redemption date (or such shorter notice as may be acceptable to the Trustee). 
 SECTION 3.2 Selection of Securities to be Redeemed. 
 Unless otherwise indicated for a
particular Series by a Board Resolution, a supplemental indenture or an Officers’ Certificate, if less than all the Securities of a Series are to be redeemed, the Trustee shall select the Securities of the Series to be redeemed in any manner
that the Trustee deems fair and appropriate. The Trustee shall make the selection from Securities of the Series outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities of the
Series that have denominations larger than $1,000. Securities of the Series and portions of them it selects shall be in amounts of $1,000 or whole multiples of $1,000 or, with respect to Securities of any Series issuable in 

  

 11 

 
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 of a Series called for redemption also apply to portions of Securities of that Series 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 but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail to each Holder whose Securities are to be redeemed and, if any Bearer
Securities are outstanding, publish on one occasion a notice in an Authorized Newspaper.

 SECTION 6.2 Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default with
respect to Securities of any Series at the time outstanding occurs and is continuing (other than an Event of Default referred to in Section 6.1(e) or (f)), then in every such case the Trustee or the Holders of not less than a majority in
principal amount of the outstanding Securities of that Series may declare the principal amount (or, if any Securities of that Series are Discount Securities, such portion of the principal amount as may be specified in the terms of such Securities)

if given by Holders), and upon any such declaration such principal amount (or specified amount) and accrued and unpaid interest, if any, shall become immediately due and payable. If an Event of Default specified in Section 6.1(e) or
(f) shall occur, the principal amount (or specified amount) of and accrued and unpaid interest, if any, on all outstanding Securities 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. 
 At any time after such a declaration of acceleration with respect to any Series has been made and before a
judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the outstanding Securities of that Series, by written notice to the Company
and the Trustee, may rescind and annul such declaration and its consequences if all Events of Default with respect to Securities of that Series, other than the non-payment of the principal and interest, if any, of Securities of that Series which
have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.13. 
 No such rescission
shall affect any subsequent Default or impair any right consequent thereon. 
 SECTION 6.3 Collection Of Indebtedness And Suits For Enforcement By

	 	(b)	default is made in the payment of principal of any Security at the Maturity thereof, or 

  

	 	(c)	default is made in the deposit of any sinking fund payment when and as due by the terms of a Security, 

 then, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and any overdue interest at the rate or rates prescribed therefor in such Securities, and,
in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or
deemed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. 
 If an Event of Default with respect to any Securities of any Series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such Series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy. 
 SECTION 6.4 Trustee May File Proofs Of Claim. 
 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other

obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of
the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise, (a) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and (b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in
any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it
for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 6.5 Trustee May Enforce Claims Without Possession Of Securities.

thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid: 
 First: To the payment of all amounts due the Trustee under
Section 7.7; and 
 Second: To the payment of the amounts then due and unpaid for principal of and interest on the Securities in respect
of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and interest, respectively; and 
 Third: To the Company. 
 SECTION 6.7 Limitation On Suits.

	 	(d)	the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 

  

	 	(e)	no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the outstanding
Securities of that Series; 

 it being understood and intended that no one or more of such Holders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to
enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 
 SECTION 6.8
Unconditional Right of Holders to Receive Principal and Interest. 
 Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest, if any, on such Security on the Stated Maturity or Stated Maturities expressed in such Security (or, in the case
of redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 SECTION 6.9 Restoration of Rights and Remedies. 
 If the Trustee or any Holder has instituted
any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as
though no such proceeding had been instituted. 
 SECTION 6.10 Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.8, no right
or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not, to the extent permitted by law, prevent the concurrent assertion
or employment of any other appropriate right or remedy. 
 SECTION 6.11 Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be. 
  

 18 

 SECTION 6.12 Control by Holders. 
 The Holders of a majority in principal amount of the outstanding Securities of any Series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such Series, provided that: 
  

	 	(a)	such direction shall not be in conflict with any rule of law or with this Indenture, 

  

	 	(b)	the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and 

  

	 	(c)	subject to the provisions of Section 6.1, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer
of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability.

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 (i) in the payment of the principal of or interest on any Security of such Series (provided,
however, that the Holders of a majority in principal amount of the outstanding Securities of any Series may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration) or (ii) in
respect of a covenant or provision hereof which 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 impair any right consequent thereon. 
 SECTION 6.14 Undertaking For Costs. 
 All
parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or
in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable
costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to
any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the outstanding Securities of any Series, or to any
suit instituted by any Holder for the enforcement of the payment of the principal of or interest on any Security on or after the Stated Maturity or Stated Maturities expressed in such Security (or, in the case of redemption, on the redemption date).

Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have one separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. This indemnification shall apply to officers, directors, employees, shareholders

payment obligations in this Section, 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 that held in trust to pay principal of and interest on particular Securities
of that Series.

 When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.1(e) or (f) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
 The provisions of this Section shall survive the termination of this Indenture. 
 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. 
 The Trustee may resign with respect to the Securities of
one or more Series by so notifying the Company at least 30 days prior to the date of the proposed resignation. The Holders of a majority in principal amount of the Securities of any Series may remove the Trustee with respect to that Series by so
notifying the Trustee and the Company. The Company may remove the Trustee with respect to Securities of one or more Series if: 
  

	 	(a)	the Trustee fails to comply with Section 7.10; 

  

	 	(b)	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; 

  

	 	(c)	a Custodian or public officer takes charge of the Trustee or its property; or 

  

	 	(d)	the Trustee becomes incapable of acting. 

 If the Trustee
resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company 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. 
 If a successor
Trustee with respect to the Securities of any 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
Securities of the applicable Series may petition any court of competent jurisdiction for 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 after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee subject to
the lien provided for in Section 7.7, 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 with respect to each Series of Securities for
which it is acting as Trustee under this Indenture. A successor Trustee shall mail a notice of its succession to each Securityholder of each such Series and, if any Bearer Securities are outstanding, publish such notice on one occasion in an
Authorized Newspaper. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee with respect to expenses and
liabilities incurred by it prior to such replacement. 
 SECTION 7.9 Successor Trustee by Merger, Etc. 
 If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor Trustee. 
 SECTION 7.10 Eligibility; Disqualification. 
  

 23

 This Indenture shall upon Company Order cease to be of further effect (except as hereinafter provided in this Section 8.1), and the Trustee, at the

the Trustee for cancellation; or 

  

	 	(ii)	all such Securities not theretofore delivered to the Trustee for cancellation (1) have become due and payable, or(2) will become due and payable at their Stated Maturity within

irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust an amount sufficient for the purpose of paying and discharging the entire indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for principal and interest to the date of such deposit (in the case of Securities which have become due and payable on or prior to the date of such deposit) or to the Stated Maturity or redemption date, as the case may be;

  

	 	(b)	the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 

  

	 	(c)	the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the

 Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Company to the Trustee under Section 7.7, and, if money shall have been deposited with the Trustee pursuant to clause (a) of this Section, the provisions of Sections 2.4, 2.7, 2.8, 8.1, 8.2 and 8.5 shall
survive.

Foreign Government Obligations deposited with the Trustee pursuant to Section 8.3 or 8.4, shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or
through any Paying Agent (other than the Company acting as its own Paying Agent) as the Trustee may determine, to the persons entitled thereto, of the principal and interest for whose payment such money has been deposited with or received by the
Trustee or to make mandatory sinking fund payments or analogous payments as contemplated by Sections 8.3 or 8.4. 

  

	 	(b)	The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against U.S. Government Obligations or Foreign Government
Obligations deposited pursuant to Sections 8.3 or 8.4 or the interest and principal received in respect of such obligations other than any payable by or on behalf of Holders. 

  

	 	(c)	The Trustee shall deliver or pay to the Company from time to time upon Company Request any U.S. Government Obligations or Foreign Government Obligations or money held by it as
provided in Sections 8.3 or 8.4 which, in the opinion of a nationally recognized firm of independent certified public accountants expressed in a written certification thereof delivered to the Trustee, are then in excess of the amount thereof which
then would have been required to be deposited for the purpose for which such U.S. Government Obligations or Foreign Government Obligations or money were deposited or received. This provision shall not authorize the sale by the Trustee of any U.S.
Government Obligations or Foreign Government Obligations held under this Indenture. 

 SECTION 8.3 Legal Defeasance of Securities of any

of this Indenture, as it relates to such outstanding Securities of such Series, shall no longer be in effect (and the Trustee, at the expense of the Company, shall, at Company Request, execute proper instruments acknowledging the same), except as
to: 
  

	 	(a)	the rights of Holders of Securities of such Series to receive, from the trust funds described in subparagraph (d) hereof, (i) payment of the principal of and each
installment of principal of and interest on the outstanding Securities of such Series on the Stated Maturity of such principal or installment of principal or interest and (ii) the benefit of any mandatory sinking fund payments applicable to the

same amounts and in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred; 

  

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

well as any additional covenants specified in a supplemental indenture for such Series of Securities or a Board Resolution or an Officers’ Certificate delivered pursuant to Section 2.2.20 (and the failure to comply with any such covenants
shall not constitute a Default or Event of Default with respect to such Series under Section 6.1) and the occurrence of any event specified in a supplemental indenture for such Series of Securities or a Board Resolution or an Officers’
Certificate delivered pursuant to Section 2.2.18 and designated as an Event of Default shall not constitute a Default or Event of Default hereunder, with respect to the Securities of such Series, provided that the following conditions shall
have been satisfied: 
  

	 	(a)	 With reference to this Section 8.4, the Company has deposited or caused to be irrevocably deposited (except as provided in Section 8.2(c)) with the

 ARTICLE 9 
 AMENDMENTS AND WAIVERS

 SECTION 9.1 Without Consent of Holders.

	 	(f)	 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 

  

 27 

	 	 
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;
or 

  

	 	(g)	to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA. 

 SECTION 9.2 With Consent of Holders. 
 The
Company and the Trustee may enter into a supplemental indenture with the written consent of the Holders of at least a majority in principal amount of the outstanding Securities of each Series affected by such supplemental indenture (including
consents obtained in connection with a tender offer or exchange offer for the Securities of such Series), for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture or of modifying in any manner the rights of the Securityholders of each such Series. Except as provided in Section 6.13, the Holders of at least a majority in principal amount of the outstanding Securities of any Series
by notice to the Trustee (including consents obtained in connection with a tender offer or exchange offer for the Securities of such Series) may waive compliance by the Company with any provision of this Indenture or the Securities with respect to
such Series. 
 It shall not be necessary for the consent of the Holders of Securities under this Section 9.2 to approve the particular
form of any proposed supplemental indenture or waiver, but it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this section becomes effective, the Company shall mail to the Holders of
Securities affected thereby and, if any Bearer Securities affected thereby are outstanding, publish on one occasion in an Authorized Newspaper, a notice briefly describing the supplemental indenture or waiver. Any failure by the Company to mail or
publish such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver. 
 SECTION 9.3 Limitations. 
 Without the consent of each Securityholder affected, an amendment or waiver may not:

  

	 	(a)	reduce the amount of Securities whose Holders must consent to an amendment, supplement or waiver; 

  

	 	(b)	reduce the rate of or extend the time for payment of interest (including default interest) on any Security; 

  

	 	(c)	reduce the principal or change the Stated Maturity of any Security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation;

  

	 	(d)	reduce the principal amount of Discount Securities payable upon acceleration of the maturity thereof; 

  

	 	(e)	waive a Default or Event of Default in the payment of the principal of or interest, if any, on any Security (except a rescission of acceleration of the Securities of any Series by
the Holders of at least a majority in principal amount of the outstanding Securities of such Series and a waiver of the payment default that resulted from such acceleration); 

  

	 	(f)	make the principal of or interest, if any, on any Security payable in any currency other than that stated in the Security; 

  

	 	(g)	make any change in Sections 6.8, 6.13, or 9.3 (this sentence); or 

  

 28 

	 	(h)	waive a redemption payment with respect to any Security.

 Every amendment to this Indenture or the Securities of one or more Series shall be set
forth in a supplemental indenture hereto that complies with the TIA as then in effect. 
 SECTION 9.5 Revocation and Effect of Consents.

 Until an amendment is set forth in a supplemental indenture or a waiver becomes effective, a consent to it by a Holder of a Security is
a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any
such Holder or subsequent Holder may revoke the consent as to his Security or portion of a Security if the Trustee receives the notice of revocation before the date of the supplemental indenture or the date the waiver becomes effective. 

Any amendment or waiver once effective shall bind every Securityholder of each Series affected by such amendment or waiver unless it is of the type
described in any of clauses (a) through (h) of Section 9.3. In that case, the amendment or waiver 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. 
 SECTION 9.6 Notation on or Exchange of Securities. 
 The Trustee may place an appropriate notation about an amendment or waiver on any Security of any Series thereafter authenticated. The Company in exchange
for Securities of that Series may issue and the Trustee shall authenticate upon request new Securities of that Series that reflect the amendment or waiver. 
 SECTION 9.7 Trustee Protected. 
 In executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.1) shall be fully protected in relying upon, an Opinion of Counsel
stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee shall sign all supplemental indentures, except that the Trustee need not sign any supplemental indenture that adversely affects its
rights.

part of any sinking fund payment with respect to the Securities of any Series to be made pursuant to the terms of such Securities (1) deliver outstanding Securities of such Series to which such sinking fund payment is applicable (other than any
of such Securities previously called for mandatory sinking fund redemption) and (2) apply as credit Securities of such Series to which such sinking fund payment is applicable and which have been repurchased by the Company or redeemed either at
the election of the Company pursuant to the terms of such Series of Securities (except pursuant to any mandatory sinking fund) or through the application of permitted optional sinking fund payments or other optional redemptions pursuant to the terms
of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received by the Trustee, together with an Officers’ Certificate with respect thereto, not later than 15 days prior to the date on
which the Trustee begins the process of selecting Securities for redemption, and shall be credited for such purpose by the Trustee at the price specified in such Securities for redemption through operation of the sinking fund and the amount of such
sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities in lieu of cash payments pursuant to this Section 11.2, the principal amount of Securities of such Series to be redeemed in order to
exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such Series for redemption, except upon receipt of a Company Order that such action be taken, and such cash payment shall be held by the Trustee
or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall from time to time upon receipt of a Company Order pay over and deliver to the Company any cash payment so being
held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that Series purchased by the Company having an unpaid principal amount equal to the cash payment required to be released to the Company.

 SECTION 11.3 Redemption Of Securities For Sinking Fund. 
  

 32 

 Not less than 45 days (unless otherwise indicated in the Board Resolution, supplemental indenture or
Officers’ Certificate in respect of a particular Series of Securities) prior to each sinking fund payment date for any Series of Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next
ensuing mandatory sinking fund payment for that Series pursuant to the terms of that Series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and
crediting of Securities of that Series pursuant to Section 11.2, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and the Company shall thereupon be obligated to pay the amount therein
specified. Not less than 30 days (unless otherwise indicated in the Board Resolution, Officers’ Certificate or supplemental indenture in respect of a particular Series of Securities) before each such sinking fund payment date the Trustee shall
select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 3.2 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in
Section 3.3. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 3.4, 3.5 and 3.6. 
 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed and attested, all as of the day and year first above written.
