supplemental indenture 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 the Indenture. 
 Section 2.02    Establishment of Terms of Series of Securities. At or prior to the
issuance of any Securities within a Series, the following shall be established (as to the Series generally, in

Company’s election or at the election of any Holder, in cash or additional securities, and the terms and conditions upon which the election may be made; 

(m) if denominated in a currency or currencies other than the currency of the United States of America, the equivalent price of the Securities
of the Series in the currency of the United States of America for purposes of determining the voting rights of Holders of the Securities of the Series; 

(n) if the amount of payments of principal, premium or interest may be determined with reference to an index, formula or other method based on

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 issuance of additional
Securities of such Series, unless otherwise provided in such Board Resolution, supplemental Indenture or Officers’ Certificate. 

Section 2.03    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. 

  
 8 













 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 2.02, 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: (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 10.04,
and (c) an Opinion of Counsel complying with Section 10.04. 
 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 lawfully be taken; or (b) if a Responsible Officer of the Trustee in good faith 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. 
 If any
successor that has replaced the Company in accordance with Article 5 has executed an indenture supplemental hereto with the Trustee pursuant to Section 5.01, any of the Securities authenticated or delivered prior to
such transaction may, from time to time, at the request of such successor, be exchanged for other Securities executed in the name of the such successor with such changes in phraseology and form as may be appropriate, but otherwise identical to the
Securities surrendered for such exchange and of like principal amount; and the Trustee, upon receipt of a Company Order of such successor, shall authenticate and deliver Securities as specified in such order for the purpose of such exchange. If
Securities shall at any time be authenticated and delivered in any new name of such successor pursuant to this provision of Section 2.03 in exchange or substitution for or upon registration of transfer of any Securities,
such successor, at the option of the Holders but without expense to them, shall provide for the exchange of all Securities then outstanding for Securities authenticated and delivered in such new name.

 Section 2.04    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 2.02, an office or agency where Securities of such Series may be presented or surrendered for payment (“Paying Agent”) and where Securities of such Series may be surrendered for registration of
transfer or exchange (“Registrar”). 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 and Paying Agent. If at any time the Company shall fail to maintain any such required Registrar or Paying Agent or shall fail to furnish the Trustee with the name and address thereof,
such presentations and surrenders 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 and surrenders. 

The Company may also from time to time designate one or more co-registrars or additional paying 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 or Paying Agent in each place so specified pursuant to
Section 2.02 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 or additional paying agent. The term “Registrar” includes any co-registrar; and the term “Paying Agent” includes any additional paying agent.

 The Company hereby appoints
[                    ] as the initial Registrar and Paying Agent for each Series unless another Registrar or Paying Agent as the case may be, is
appointed prior to the time Securities of that Series are first issued. Each Registrar and Paying Agent shall be entitled to all of the rights, protections, exculpations and indemnities afforded to the Trustee in connection with its roles as
Registrar and Paying Agent. 
 Section 2.05    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) shall have no further liability for the money. If
the Company or a Subsidiary 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 2.06    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 [                    ] 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. 

  
 10 













 Section 2.07    Transfer and Exchange. 

Where Securities of a Series are presented to the Registrar or a co-registrar with a request to
register a transfer or to exchange them for an equal principal amount of Securities of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To permit registrations of
transfers and exchanges, the Trustee shall authenticate Securities at the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax
or other governmental charge required by law; provided that this sentence shall not apply to any exchange pursuant to Section 2.11, 2.08, 3.06 or 9.06. 

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 [                    ] 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. 
 All Securities issued upon any
transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. Any Registrar appointed
pursuant to Section 2.04 shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. Each
Holder of a Security agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable
U.S. federal or state securities law. 
 Section 2.08    Mutilated, Destroyed, Lost and Stolen Securities.

 If any mutilated Security is surrendered to the Registrar, the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a new Security of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

If there shall be delivered to the Company and the Registrar (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 Registrar 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 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. 

  
 11 













 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 2.09    Outstanding Securities. 

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

If a Security is replaced pursuant to Section 2.08, it ceases to be outstanding until the Trustee receives proof
satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 If the Paying Agent (other than the Company, a Subsidiary
or an Affiliate of any thereof) 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 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 6.02. 
 Section
2.10    Treasury Securities. In determining whether the Holders of the required principal amount of Securities of a Series have concurred in any request, demand, authorization, direction, notice, consent or waiver
Securities of a Series owned by the Company or an Affiliate 

  
 12 













 
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 a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. 
 Section
2.11    Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary securities upon a Company Order (“Temporary
Securities”). 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 written 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 or its agent any Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee and no one else shall cancel, in accordance with its standard procedures, all Securities surrendered for transfer, exchange, payment,
conversion or cancellation and shall deliver the cancelled Securities to the Company. No Security shall be authenticated in exchange for any Security cancelled pursuant to this Section 2.12. 

The Company may, to the extent permitted by law, purchase Securities in the open market or by tender offer at any price or by private
agreement. Any Securities purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the final maturity of such Securities may, to the extent permitted by law, be reissued or resold or may, at the option of the Company, be
surrendered to the Trustee for cancellation. Any Securities surrendered for cancellation may not be reissued or resold and shall be promptly cancelled by the Trustee, and the Company may not hold or resell such Securities or issue any new Securities
to replace any such Securities. 
 Section 2.13    Defaulted Interest. If the Company defaults in a payment
of interest on a Series of Securities, it shall pay defaulted interest, plus, to the extent permitted by law, any interest payable on the defaulted interest at the Default Rate, to the persons who are Security holders of the Series on a subsequent
special record date. The Company shall fix the record date and payment date. At least [ ] days before the record date, the Company shall mail to the Trustee and the Paying Agent 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. 

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

  
 13 













 (b) Notwithstanding any provisions to the contrary contained in Section 2.07 of the
Indenture and in addition thereto, any Global Security shall be exchangeable pursuant to Section 2.07 of the Indenture for Securities registered in the names of Holders other than the Depository for such Security or its nominee only if
(A) 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 within 90 days of such event, (B) the Company executes and delivers to the Trustee an Officers’ Certificate to the effect that such Global Security shall be so exchangeable
or (C) an Event of Default with respect to the Securities represented by such Global Security shall have happened and be continuing. 

(i) 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. 
 (ii) Securities issued in exchange for a Global Security or any portion thereof shall be
issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized
denominations as the Depository shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depository to the Trustee, as Registrar. With regard to any Global
Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Registrar is acting as custodian for the Depository or its nominee with respect to such Global Security, the principal amount thereof shall
be reduced by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security
issuable on such exchange to or upon the order of the Depository or an authorized representative thereof. 
 (iii) The
registered Holder may grant proxies and otherwise authorize any Person, including participants in the Depository and persons that may hold interests through participants in the Depository, to take any action which a Holder is entitled to take under
this Indenture or the Securities. 
 (iv) In the event of the occurrence of any of the events specified in 2.14(b)(i), the
Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. If (A) an event described in Section 2.14(b)(i)(A) or
(B) occurs and definitive Certificated Securities are not issued promptly to all beneficial owners or (B) the Registrar receives from a beneficial owner instructions to obtain definitive Certificated Securities due to
an event described in Section 2.14(b)(i)(C) and definitive Certificated Securities are not 

  
 14 













 
issued promptly to any such beneficial owner, the Company expressly acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to Section 6.07 hereof, the right of any
beneficial owner of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial owner’s Securities as if such definitive certificated Securities had been issued. 

(v) Notwithstanding any provision to the contrary in this Indenture, so long as a Global Security remains outstanding and is
held by or on behalf of the Depository, transfers of a Global Security, in whole or in part, or of any beneficial interest therein, shall only be made in accordance with Section 2.07, this Section 2.14(b) and the rules and
procedures of the Depository for such Global Security to the extent applicable to such transaction and as in effect from time to time. 

(c) Any Global Security issued hereunder shall bear a legend in substantially the following form: 

“This Security is a Global Security within the meaning of the Indenture hereinafter referred to and is registered in the name of the
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) 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. 

(e) 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 at their registered office. 
 (f) At all
times the Securities are held in book-entry form with a Depository, (i) the Trustee may deal with such Depository as the authorized representative of the Holders, (ii) the rights of the Holders shall be exercised only through the
Depository and shall be limited to those established by law and agreement between the Holders and the Depository and/or direct participants of the Depository, (iii) the Depository will make book-entry transfers among the direct
participants of the Depository and will receive and transmit distributions of principal and interest on the Securities to such direct participants; and (iv) the direct participants of the Depository shall have no rights under this Indenture, or any
supplement hereto, under or with respect to any of the Securities held on their behalf by the Depository, and the Depository may be treated by the Trustee and its agents, employees, officers and directors as the absolute owner of the Securities for
all purposes whatsoever. 
 Section 2.15    CUSIP Numbers. The Company in issuing the Securities may use
“CUSIP”, “CCN”, “ISIN” or other identification numbers (if then generally in use), and, if so, 

  
 15 













 
the Trustee shall use “CUSIP”, “CCN”, “ISIN” or such other identification 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 III 

REDEMPTION 

Section 3.01    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 and Registrar in writing of
the redemption date and the principal amount of Series of Securities to be redeemed. The Company shall give the notice at least
[                    ] days before the redemption date (or such shorter notice as may be acceptable to the Trustee and Registrar). 

Section 3.02    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 Registrar shall select the Securities of the Series to be redeemed in accordance with its
customary procedures. The Registrar shall make the selection from Securities of the Series outstanding not previously called for redemption. The Registrar 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 other denominations pursuant to
Section 2.02(g), 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 3.03    Notice of Redemption. Unless otherwise indicated for a particular
Series by Board Resolution, a supplemental indenture hereto or an Officers’ Certificate, at least [                    ] days but not more than
[                    ] 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. 
 The notice shall identify the Securities of the Series to be redeemed and shall state: 

(a) the redemption date; 
 (b)
the redemption price; 
 (c) the name and address of the Paying Agent; 

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

  
 16 













 (e) that interest on Securities of the Series called for redemption ceases to accrue on and
after the redemption date; and 
 (f) any other information as may be required by the terms of the particular Series or the Securities of a
Series being redeemed. 
 At the Company’s written request, the Trustee shall distribute the notice of redemption prepared by the
Company in the Company’s name and at its expense. 
 Section 3.04 Effect of Notice of Redemption. Once notice of redemption
is mailed or published as provided in Section 3.03, Securities of a Series called for redemption become due and payable on the redemption date and at the redemption price. A notice of redemption may not be conditional. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption price plus accrued interest to the redemption date. 

Section 3.05 Deposit of Redemption Price. On or before the redemption date, the Company shall deposit with the Paying Agent money
sufficient to pay the redemption price of and accrued interest, if any, on all Securities to be redeemed on that date. 
 Section 3.06
Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Trustee shall authenticate for the Holder a new Security of the same Series and the same maturity equal in principal amount to the unredeemed portion of
the Security surrendered. 
 ARTICLE IV 

COVENANTS 

Section 4.01 Payment of Principal and Interest. The Company covenants and agrees for the benefit of the Holders of each Series of
Securities that it will duly and punctually pay the principal of and interest, if any, on the Securities of that Series in accordance with the terms of such Securities and this Indenture. 

Unless otherwise provided under the terms of a particular Series of Securities: 

(a) an installment of principal or interest shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds
by [                    ] [a].m., New York City time, on that date money, deposited by the Company or an Affiliate thereof, sufficient to pay such
installment. The Company shall (in immediately available funds), to the fullest extent permitted by law, pay interest on overdue principal and overdue installments of interest at the rate borne by the Securities per annum; and 

(b) payment of the principal of and interest on the Securities shall be made at the office or agency of the Company maintained for that
purpose in [                    ] (which shall initially be
[                    ], the Paying Agent) in such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address appears in the register;
provided, further, that a Holder with an aggregate principal amount in excess of $[        ] will be paid by wire transfer in immediately available funds at the election of such Holder if such
Holder has provided wire transfer instructions to the Company at least [                    ] Business Days prior to the payment date.

 Section 4.02 SEC Reports. 

So long as any Securities are outstanding, the Company shall (i) file with the SEC within the time periods prescribed by its rules and
regulations and (ii) furnish to the Trustee and the Holders of the Securities within [    ] days after the date on which the Company would be required to file the same with the SEC pursuant to its rules and regulations
(giving effect to any grace period provided by Rule 12b-25 under the Exchange Act), all quarterly and annual financial information required to be furnished or filed with the SEC pursuant to
Section 13 and Section 15(d) of the Exchange Act and, with respect to the annual consolidated financial statements only, a report thereon by the Company’s independent auditors. The Company
also shall comply with the other provisions of TIA Section 314(a). 
 Delivery of such reports, information and documents to the
Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s
compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Company shall not be required to file any report or other information with the SEC if the SEC does not
permit such filing, although such reports shall be furnished to the Trustee. Documents filed by the Company with the SEC via the SEC’s EDGAR system (or any successor thereto) will be deemed furnished to the Trustee and the Holders of the
Securities as of the time such documents are filed via EDGAR (or such successor). 
 Section 4.03 Compliance Certificate. 

The Company shall deliver to the Trustee, within [    ] days after the end of each fiscal year of the Company, an officers
certificate signed by two of the Company’s officers stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his knowledge the Company has kept,
observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have
occurred, describing all such Defaults or Events of Default of which he may have knowledge in reasonable detail and the efforts to remedy the same). For purposes of this Section 4.03, compliance shall be determined without
regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture. 
 The Company shall deliver to the
Trustee, within [    ] days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any Event of Default described in Section 6.01(e), (f), (g) or
(h) and any event of which it becomes aware that with the giving of notice or the lapse of time would become such an Event of Default, its status and what action the Company is taking or proposes to take with respect thereto. For the
avoidance of doubt, a breach 

  
 18 













 
of a covenant under an Instrument that is not a payment default and that has not given rise to a right of acceleration under such Instrument shall not trigger the requirement to provide notice
under this paragraph. 
 Section 4.04 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully
do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture or the Securities; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, 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 has been enacted. 

Section 4.05 Corporate Existence. Subject to Article V, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each Subsidiary in accordance with the respective organizational documents of each Subsidiary and the rights (charter and
statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any Subsidiary,
if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries taken as a whole and that the loss thereof is not adverse in any material respect to
the Holders. 
 Section 4.06 Taxes. The Company shall, and shall cause each of its Subsidiaries to, pay prior to delinquency all
taxes, assessments and governmental levies, except as contested in good faith and by appropriate proceedings. 
 Section 4.07
Additional Interest Notice. In the event that the Company is required to pay additional interest to Holders of Securities pursuant to Section 6.02(b) hereof, the Company shall provide a direction or order in the form of a written
notice to the Trustee (and if the Trustee is not the Paying Agent, the Paying Agent) of the Company’s obligation to pay such additional interest no later than [    ] Business Days prior to date on which any such additional
interest is scheduled to be paid. Such notice shall set forth the amount of additional interest to be paid by the Company on such payment date and direct the Trustee (or, if the Trustee is not the Paying Agent, the Paying Agent) to make payment to
the extent it receives funds from the Company to do so. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether additional interest is payable, or with respect to the nature, extent, or calculation of
the amount of additional interest owed, or with respect to the method employed in such calculation of additional interest. 

Section 4.08 Further Instruments and Acts. The Company will execute and deliver such further instruments and do such further acts
as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

share exchange, or merge into any other Person in a transaction in which it is not the surviving entity, or sell, assign, convey, transfer or lease or otherwise dispose of all or substantially all of its properties and assets to any Person (a
“successor person”), unless: 
 (a)    the successor person (if any) is a corporation, partnership,
trust or other entity organized and validly existing under the laws of the Kingdom of Belgium, [    ], the United States, any state of the United States or the District of Columbia and expressly assumes by a supplemental
indenture executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of, and any interest on, all Securities and the performance or observance of every covenant of this Indenture on the
part of the Company to be performed or observed; 
 (b)    immediately after giving effect to the transaction, no
Default or Event of Default, shall have occurred and be continuing; and 
 (c)    the Company shall have delivered to
the Trustee, prior to the consummation of the proposed transaction, an Officers’ Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture comply with this Indenture.

sale, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor person has been named as the Company
herein; provided, however, that the predecessor company in the case of a sale, lease, conveyance or other disposition of all or substantially all of the assets of the Company shall not be released from the obligation to pay the principal of and
interest, if any, on the Securities. 
 ARTICLE VI 

DEFAULTS 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:

 (a)    default in the payment of any interest on any Security of that Series when it becomes due and payable, and
continuance of such default for a period of 30 days (unless the entire amount of such payment is deposited by the Company with the Trustee or with a Paying Agent prior to the expiration of such period of 30 days); or 

  
 20 













 (b)    default in the payment of any principal of any Security of that
Series at its Maturity; or 
 (c)    default in the deposit of any sinking fund payment, when and as due in respect of
any Security of that Series; or 
 (d)    the Company fails to perform or comply with any of its other covenants or
agreements contained in the Securities or in this Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in clauses (a), (b) or (c) of this Section 6.01) and the
default continues for 60 days after notice is given as specified below; 
 (e)    any indebtedness under any bond,
debenture, note or other evidence of indebtedness for money borrowed by the Company or any Subsidiary or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for
money borrowed by, or any other payment obligation of, the Company or any Subsidiary (an “Instrument”) with a principal amount then, individually or in the aggregate, outstanding in excess of $[    ], whether
such indebtedness now exists or shall hereafter be created, is not paid at Maturity or when otherwise due or is accelerated, and such indebtedness is not discharged, or such default in payment or acceleration is not cured or rescinded, within a
period of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least [    ]% in aggregate principal amount of the
outstanding Securities of that Series a written notice specifying such default and requiring the Company to cause such indebtedness to be discharged or cause such default to be cured or waived or such acceleration to be rescinded or annulled and
stating that such notice is a “Notice of Default” hereunder. A payment obligation (other than indebtedness under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company or any Subsidiary or
under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or any Subsidiary) shall not be deemed to have matured, come due, or been
accelerated to the extent that it is being disputed by the relevant obligor or obligors in good faith. For the avoidance of doubt, the Maturity of an Instrument is the Maturity as set forth in that Instrument, as it may be amended from time to time
in accordance with the terms of that Instrument; 
 (f)    the Company or any Subsidiary fails to pay one or more final
and non-appealable judgments entered by a court or courts of competent jurisdiction, the aggregate uninsured or unbonded portion of which is in excess of $[    ], if the judgments are not
paid, discharged, waived or stayed within [    ] days; 
 (g)    the Company or any Subsidiary of
the Company, pursuant to or within the meaning of any Bankruptcy Law: 
 (i)    commences a voluntary
case or proceeding; 
 (ii)    consents to the entry of an order for relief against it in an involuntary
case or proceeding; 

  
 21 













 (iii)    consents to the appointment of a Custodian of
it or for all or substantially all of its property; or 
 (iv)    makes a general assignment for the
benefit of its creditors; or 
 (v)    or generally is unable to pay its debts as the same become due; or

 (h)    a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(i)    is for relief against the Company or any of its Subsidiaries in an involuntary case or proceeding;

 (ii)    appoints a Custodian of the Company or any of its Subsidiaries for all or substantially all of
the property of the Company or any such Subsidiary; or 
 (iii)    orders the liquidation of the Company
or any of its Subsidiaries; 
 and the case of each of clause (i), (ii) and (iii), the order or decree remains unstayed and in effect for
[    ] consecutive days; or 
 (iv)    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(i). 

A default under clause (d) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least
[    ]% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, in writing of the default, and the Company does not cure the default within 60 days after receipt of such notice. The
notice given pursuant to this Section 6.01 must specify the default, demand that it be remedied and state that the notice is a “Notice of Default.” When any default under this Section 6.01 is cured, it
ceases. 
 The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a
Trust Officer at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder. 

Section 6.02    Acceleration of Maturity; Rescission and Annulment. 

(a)    If an Event of Default (other than an Event of Default specified in clause (g) or (h) of
Section 6.01) occurs and is continuing with respect to any Securities of any Series, then in every such case, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities of
that Series (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) then outstanding may, by notice to the Company and the Trustee, declare all unpaid
principal of, and accrued and unpaid interest on to the date of acceleration, the Securities of that Series then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately
due and payable. If an Event of Default specified in clause (g) or (h) of Section 6.01 occurs, all unpaid principal of 

  
 22 













 
the Securities then outstanding, and all accrued and unpaid interest thereon to the date of acceleration, shall ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities of that Series then outstanding by notice to the Trustee may rescind an acceleration of such Securities of that Series and
its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) to the extent the payment
of such interest is lawful, interest (calculated at the Default Rate) on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would
not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under Section 7.07 have been made. No such rescission shall affect any subsequent
default or impair any right consequent thereto. 
 (b)    Notwithstanding any of provision of this Article 6, at
the election of the Company in its sole discretion, the sole remedy under this Indenture for an Event of Default relating to the failure to comply with Section 4.02, and for any failure to comply with the requirements of
Section 314(a)(1) of the TIA, will consist, for the 180 days after the occurrence of such an Event of Default, exclusively of the right to receive additional interest on the Securities at a rate equal to 0.50% per annum of the aggregate
principal amount of the Securities then outstanding up to, but not including, the 181st day thereafter (or, if applicable, the earlier date on which the Event of Default relating to Section 4.02 is cured or waived). Any such additional
interest will be payable in the same manner and on the same dates as the stated interest payable on the Securities. In no event shall additional interest accrue under the terms of this Indenture at a rate in excess of 0.50% per annum, in the
aggregate, for any violation or default caused by the failure of the Company to be current in respect of its Exchange Act reporting obligations. If the Event of Default is continuing on the 181st day after an Event of Default relating to a failure
to comply with Section 4.02, the Securities will be subject to acceleration as provided in this Section 6.02. The provisions of this Section 6.02(b) will not affect the rights of Holders in the event of the
occurrence of any other Events of Default. 
 In order to elect to pay additional interest as the sole remedy during the first 180 days
after the occurrence of an Event of Default relating to the failure to comply with Section 4.02 in accordance with the immediately preceding paragraph, the Company shall notify all Holders and the Trustee and Paying Agent of such
election on or before the close of business on the fifth Business Day after the date on which such Event of Default otherwise would occur. Upon a failure by the Company to timely give such notice or pay additional interest, the Securities will be
immediately subject to acceleration as otherwise provided in this Section 6.02. 

Section 6.03    Collection of Indebtedness and Suits for Enforcement by Trustee. 

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. 

  
 23 













 If an Event of Default in the payment of principal, interest, if any, specified in clause
(a) or (b) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount of principal, and
accrued interest remaining unpaid, if any, together with, to the extent that payment of such interest is lawful, interest on overdue principal, on overdue installments of interest, if any, in each case at the Default Rate, 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 the Trustee, its agents and counsel. 

Section 6.04    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 7.07. 
 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 6.05    Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims
under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for
the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 

  
 24 













 Section 6.06    Application of Money Collected. Any money
collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon presentation of the
Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: and 
 First: To
the payment of all amounts due the Trustee under Section 7.07; 
 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 6.07    Limitation on Suits. No Holder of any Security of any Series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture or the Securities or any related coupon, or for the appointment of a receiver or trustee, or for any other remedy hereunder (except actions for payment of overdue principal and
interest), unless: 
 (a)    such Holder has previously given written notice to the Trustee of a continuing Event of
Default with respect to the Securities of that Series; 
 (b)    the Holders of not less than
[    ]% in principal amount of the outstanding Securities of that Series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(c)    such Holder or Holders have offered to the Trustee indemnity satisfactory to it against the costs, expenses and
liabilities to be incurred in compliance with such request; 
 (d)    the Trustee for [    ] 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 [    ]-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 6.08    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. 

  
 25 













 Section 6.09    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 2.08, no right or remedy herein conferred upon or reserved to the Trustee or
to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at
law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 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. 

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 6.01, 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 or would be unduly prejudicial to the rights
of another Holder or the Trustee. 
 Section 6.13    Waiver of Past Defaults. Subject to
Section 9.02, the Holders of not less than a majority in principal amount of the outstanding Securities of any Series may on behalf of the Holders of all the Securities of such Series waive any past Default hereunder with respect to such
Series and its consequences, except a Default 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 

  
 26 













 
consequences, including any related payment default that resulted from such acceleration). 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 [    ]% 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). 

ARTICLE VII 
 TRUSTEE

 Section 7.01    Duties of Trustee. 

(a)    If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in
it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. 

(b)    Except during the continuance of an Event of Default: 

(i)    The Trustee need perform only those duties that are specifically set forth in this Indenture and no
implied duties, covenants or obligations shall be deemed to be imposed upon the Trustee. 
 (ii)    in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon Officers’ Certificates or Opinions of Counsel furnished to the Trustee and
conforming to the requirements of this Indenture; however, in the case of any such Officers’ Certificates or Opinions of Counsel which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine
such Officers’ Certificates and Opinions of Counsel to determine whether or not they conform on their face to the requirements of this Indenture. 

(c)    The Trustee may not be relieved from liability for its own its own negligent action, its own negligent failure to
act or willful misconduct, except that: 

  
 27 













 (i)    This paragraph does not limit the effect of
paragraph (b) of Section 7.01 herein. 
 (ii)    The Trustee shall not be liable for any
error of judgment made in good faith by a Responsible Officer. 
 (iii)    The Trustee shall not be
liable with respect to any action taken, suffered or omitted to be taken by it with respect to Securities of any Series in good faith in accordance with the direction of the Holders of a majority in principal amount of the outstanding Securities of
such Series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such Series.

 (d)    Every provision of this Indenture that in any way relates to the Trustee is subject to paragraph (a), (b) and
(c) of this Section. 
 (e)    The Trustee may refuse to perform any duty or exercise any right or power unless it
receives an indemnity satisfactory to it against any loss, liability or expense. 
 (f)    The Trustee shall not be
liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

(g)    No provision of this Indenture shall require the Trustee to risk or expend its own funds or otherwise incur
liability, financial or otherwise, in the performance of any of its duties, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against
such risk is not reasonably assured to it. 
 (h)    The Paying Agent, the Registrar and any authenticating agent shall
be entitled to the same rights, indemnities, protections and immunities afforded to the Trustee. 
 (i)    The Trustee
shall have no duty to monitor the performance or compliance of the Company with its obligations hereunder or any under supplement hereto, nor shall it have any liability in connection with the malfeasance or nonfeasance by the Company. The Trustee
shall have no liability in connection with compliance by the Company with statutory or regulatory requirements related to this Indenture, any supplement or any Securities issued pursuant hereto or thereto. 

Section 7.02    Rights of Trustee. 

(a)    The Trustee may conclusively rely on and shall be fully protected in acting or refraining from acting as a result of
its reasonable belief that any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, direction, approval or other paper or document was genuine and had been signed or presented by the proper person. The
Trustee need not investigate any fact or matter stated in the document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it sees fit. 

  
 28 













 (b)    Before the Trustee acts or refrains from acting, it may require
an Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. 

(c)    The Trustee may act through agents and shall not be responsible for the misconduct or negligence of, or for the
supervision of, any agent appointed with due care. No Depository shall be deemed an agent of the Trustee and the Trustee shall not be responsible for any act or omission by any Depository. 

(d)    The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be
authorized or within its rights or powers. 
 (e)    The Trustee may consult with counsel of its selection and the
advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

(f)    The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by or pursuant to
this Indenture at the request, order or direction of any of the Holders of Securities, unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities which might
be incurred by it in compliance with such request or direction. 
 Section 7.03    Individual Rights of
Trustee. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights. The Trustee is also subject to Sections 7.10 and 7.11. 

Section 7.04    Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy
of this Indenture or the Securities and the recitals contained herein and in the Securities shall be taken as statements of the Company and not of the Trustee, and the Trustee has no responsibility for such recitals. The Trustee shall not be
accountable for the Company’s use or application of the proceeds from the Securities or for monies paid over to the Company pursuant to this Indenture, and it shall not be responsible for any statement in the Securities other than its
authentication. 
 Section 7.05    Notice of Defaults. If a Default or Event of Default occurs and is
continuing with respect to the Securities of any Series and if a Responsible Officer of the Trustee has knowledge or receives written notice of such event, the Trustee shall mail to each Securityholder of the Securities of that Series, notice of a
Default or Event of Default within [    ] days after it occurs or, if later, after a Responsible Officer of the Trustee has actual knowledge of such Default or Event of Default. Except in the case of a Default or Event of Default
in payment of principal of or interest on any Security of any Series, including any additional interest that may become payable pursuant to Section 6.02(b), the Trustee may withhold the notice so long as the Trustee in good faith
determines that withholding the notice is in the interests of Securityholders of that Series. 

  
 29 













 Section 7.06    Reports by Trustee to Holders. 

Within [    ] days after [    ] in each year, the Trustee shall transmit by mail to all
Securityholders, as their names and addresses appear on the register kept by the Registrar, a brief report dated as of such [    ], in accordance with, and to the extent required under, TIA Section 313. 

A copy of each report at the time of its mailing to Securityholders of any Series shall be filed with the SEC and each stock exchange on which
the Securities of that Series are listed. The Company shall promptly notify the Trustee when Securities of any Series are listed on any stock exchange. 

Section 7.07    Compensation and Indemnity. 

The Company shall pay to the Trustee from time to time such compensation for its services as shall be agreed upon in writing. The
Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses, disbursements and advances incurred by it. Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents,
counsel and other persons not regularly in its employ. 
 The Company shall indemnify, defend and hold harmless the Trustee and its
officers, directors, employees, representatives and agents, from and against and reimburse the Trustee for any and all claims, expenses, obligations, liabilities, losses, damages, injuries (to person, property, or natural resources), penalties,
stamp or other similar taxes, actions, suits, judgments, reasonable costs and expenses (including reasonable attorney’s and agent’s fees and expenses) of whatever kind or nature regardless of their merit, demanded, asserted or claimed
against the Trustee directly or indirectly relating to, or arising from, claims against the Trustee by reason of its participation in the transactions contemplated hereby, including without limitation all reasonable costs required to be associated
with claims for damages to persons or property, and reasonable attorneys’ and consultants’ fees and expenses and court costs except to the extent caused by the Trustee’s negligence or willful misconduct. The provisions of this
Section 7.07 shall survive the termination of this Agreement or the earlier resignation or removal of the Trustee. The Company shall defend any claim and the Trustee shall cooperate in the defense. The Trustee may have 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 or delayed. This indemnification shall apply to
officers, directors, employees, shareholders and agents of the Trustee. 
 The Company need not reimburse any expense or indemnify against
any loss liability incurred by the Trustee or by any officer, director, employee, shareholder or agent of the Trustee through negligence or bad faith. 

To secure the Company’s 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 and interest on particular Securities of that Series. 

  
 30 













 When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.01(f) or (g) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 

Section 7.08    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. 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 [    ]
days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least [    ] % 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 7.07, and subject to the payment of
any and all amounts then due and owing to the retiring 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 a notice of its succession to each Securityholder of each such Series. Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring trustee with respect to expenses and liabilities incurred by it prior to such replacement. 

  
 31 













 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 successor corporation without any further act shall be the successor Trustee with the same effect
as if the successor Trustee had been named as the Trustee herein. 
 Section 7.10    Eligibility;
Disqualification. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a) (1), (2) and (5). The Trustee shall always have a combined capital and surplus of at least $25,000,000 as set forth in its
most recent published annual report of condition. The Trustee shall comply with TIA Section 310(b). 

Section 7.11    Preferential Collection of Claims Against Company. The Trustee is subject to TIA
Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TTA Section 311(a) to the extent indicated.

hereunder by the Company; and 
 (c)    the Company has delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each meeting the applicable requirements of Sections 10.04 and 10.05 and each stating that all conditions precedent herein relating to the satisfaction and discharge of this Indenture have been complied with and the
Trustee receives written demand from the Company to discharge. 
 Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.07, and, if money shall have been deposited with the Trustee pursuant to clause (a) of this Section, the provisions of Sections 2.04, 2.07, 2.08,
8.01 8.02 and 8.05 shall survive. 
 Section 8.02    Application of Trust Funds;
Indemnification.

of U.S. Government Obligations or Foreign Government Obligations deposited with the Trustee pursuant to Section 8.03 or 8.04, 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 (including 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 8.03 or 8.04. 

(b)    The Company shall pay and shall indemnify the Trustee and the Agents against any tax, fee or other charge imposed

which, in the opinion of a nationally recognized firm of independent certified public accountants, expressed in a written certification thereof and delivered to the Trustee together with such Company Request, 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. 

  
 33 













 Section 8.03    Legal Defeasance of Securities of any
Series. Unless this Section 8.03 is otherwise specified, pursuant to Section 2.02(s), to be inapplicable to Securities of any Series, the Company shall be deemed to have paid and discharged the entire indebtedness on all
the outstanding Securities of such Series on the [    ] day after the date of the deposit referred to in subparagraph (d) hereof, and the provisions 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:

Currency (other than a composite currency), money and/or Foreign Government Obligations, which through the payment of interest and principal in respect thereof, in accordance with their terms, will provide (and without reinvestment and assuming no
tax liability will be imposed on such Paying Agent), not later than [    ] day before the due date of any payment of money, an amount in cash, sufficient, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee and the Paying Agent, to pay and discharge each installment of principal (including mandatory sinking fund or analogous payments) of and interest, if any, on all the
Securities of such Series on the dates such installments of interest or principal are due;

(f)    no Default or Event of Default with respect to the Securities of such Series shall have occurred and be continuing
on the date of such deposit or during the period ending on the [    ] day after such date;

case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the Securities of such Series will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit, defeasance and
discharge and will be subject to Federal income tax on the same amount 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;

in the Investment Company Act of 1940, as amended), or such trust shall be qualified under such Act or exempt from regulation thereunder; and 

(j)    the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each

irrevocably deposited (except as provided in Section 8.02(c)) with the Paying Agent as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities (i) in the

recognized firm of independent certified public accountants expressed in a written certification thereof delivered to the Paying Agent, to pay principal and interest, if any, on and any mandatory sinking fund in respect of the Securities of such
Series on the dates such installments of interest or principal are due;

 ARTICLE IX 

AMENDMENTS AND WAIVERS 

Section 9.01    Without Consent of Holders. Subject to Section 9.02 and Section 9.03,
the Company and the Trustee may amend or supplement this Indenture or the Securities of one or more Series without the consent of any Securityholder: 

(a)    to cure any ambiguity, defect or inconsistency; 

(b)    to comply with Article V; 

(c)    to provide for uncertificated Securities in addition to or in place of certificated Securities; 

  
 36 













 (d)    to make any change that does not adversely affect the rights of
any Securityholder; 
 (e)    to provide for the issuance of and establish the form and terms and conditions of
Securities of any Series as permitted by this Indenture; 
 (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 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; 
 (g)    to comply with requirements of the TIA and any rules promulgated under the
TIA; and 
 (h)    to add to the covenants of the Company for the equal and ratable benefit of the Holders or to
surrender any right, power or option conferred upon the Company. 
 Any amendment or supplement made solely to conform the provisions of
this Indenture or the Securities of any Series to the description thereof contained in the final prospectus relating to such Series will be deemed not to adversely affect the rights of any Holder. 

Section 9.02    With Consent of Holders. 

Subject to Section 9.03, 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 all Series affected by such supplemental indenture, taken together as one class (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 all Series affected by such waiver by notice to the Trustee, taken together
as one class (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 9.02 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 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 9.03    Limitations. Without the consent of each Securityholder
affected, an amendment or waiver may not: 

  
 37 













 (a)    change the amount of Securities whose Holders must consent to an
amendment, supplement or waiver, except to increase any such amount or to provide that certain provisions of this Indenture cannot be modified, amended or waived without the consent of the Holder of each outstanding Security affected thereby; 

(b)    reduce the amount of interest, or change the interest payment time, on any Security; 

(c)    waive a redemption payment or alter the redemption provisions (other than any alteration that would not materially
adversely affect the legal rights of any Holder under this Indenture) or the price at which the Company is required to offer to purchase the Securities; 

(d)    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; 
 (e)    reduce the principal amount payable of any
Security upon Maturity; 
 (f)    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); 
 (g)    change the place or currency of payment of principal of or interest, if any, on any
Security other than that stated in the Security; 
 (h)    impair the right of any Holder to receive payment of
principal or, or interest on, the Securities of such Holder on or after the due dates therefor; 
 (i)    impair the
right to institute suit for the enforcement of any payment on, or with respect to, any Security; 
 (j)    make any
change in Sections 10.15 or 10.16; 
 (k)    change the ranking of the Securities; or 

(l)    make any other change which is specified in a Board Resolution, a supplemental indenture hereto or an
Officers’ Certificate as a limitation under this Section. 
 For the avoidance of doubt, any amendment or waiver shall always be
subject to the consent of the Company. 
 Section 9.04    Compliance with 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 TIA as then in effect. 

  
 38 













 Section 9.05    Revocation and Effect of Consents. 

Until an amendment 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 if the Trustee receives the notice of revocation before the date the amendment or 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 (g) of Section 9.03 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 9.06    Notation on or
Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee and the Trustee may place an appropriate notation on the Security
about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company shall issue and the Trustee shall authenticate upon request new Securities of that Series that reflect the changed terms.

 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 or an Officer’s Certificate, or both 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, duties or indemnities. 

Section 9.08    Effect of Supplemental Indenture. Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and each such supplemental indenture shall form part of this Indenture for all purposes with respect to the relevant Series; and every Holder of Securities of the relevant Series
theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

 Any notice or communication to a Securityholder shall be mailed by first-class mail to his address shown on the register

 If the company mails a notice or communication to Securityholders, it will mail a copy to the Trustee and

provided for in this Indenture relating to the proposed action have been complied with; and 
 (b)    an Opinion of
Counsel stating that, in the opinion of counsel, all such conditions precedent (including any covenants, compliance with which constitutes a condition precedent) have been complied with. 

Section 10.05    Statements Required in Certificate or Opinion. Each certificate or opinion with respect to
compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA Section 314(a)(4)) shall comply with the provisions of TIA Section 314(e) and shall include:

 provided, however, that with respect to matters of fact an Opinion of Counsel may rely on an Officers’ Certificate or certificates of

 Section 10.06    Record Date for Vote or Consent of Holders. The Company (or, in the
event deposits have been made pursuant to Section 11.02, the Trustee) may set a record date for purposes of determining the identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under
this Indenture, which record date shall not be more than [    ] days prior to the date of the commencement of solicitation of such action. Notwithstanding the provisions of Section 9.05, if a record date is fixed,
those persons who were Holders of Securities at the close of business on such record date (or their duly designated proxies), and only those persons, shall be entitled to take such action by vote or consent or to revoke any vote or consent
previously given, whether or not such persons continue to be Holders after such record date. 

Section 10.07    Rules by Trustee and Agents. The Trustee may make reasonable rules for action by or a meeting
of Securityholders of one or more Series. Any Agent may make reasonable rules and set reasonable requirements for its functions.

 Section 10.08    Legal Holidays. Unless otherwise provided
by Board Resolution, Officers’ Certificate or supplemental indenture for a particular Series, a “Legal Holiday” is any day that is not a Business Day. If a payment date is a Legal Holiday at a place of payment, payment may be
made at that place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. 

Section 10.09    No Recourse Against Others. A director, officer, employee or stockholder, as such, of the
Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Securityholder by accepting a Security
waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

Section 10.10    Counterparts. This Indenture may be executed in any number of counterparts and by the parties
hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 

Section 10.11    Governing Laws and Submission to Jurisdiction. 

THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK EXCLUDING ANY RULE OF LAW THAT WOULD CAUSE THE
APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK. 
 The Company agrees that any legal suit, action or
proceeding arising out of or based upon this Indenture may be instituted in any federal or state court sitting in New York City, and, to the fullest extent permitted by law, waives any objection which it may now or hereafter have to the laying of
venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such court in any suit, action or proceeding. The Company, as long as any Securities remain outstanding or the parties
hereto have any obligation under this Indenture, shall have an authorized agent in the United States upon whom process may be served in any such legal action or proceeding. Service of process upon such agent and written notice of such service mailed
or delivered to it shall to the extent permitted by law be deemed in every respect effective service of process upon it in any such legal action or proceeding and, if it fails to maintain such agent, any such process or summons may be served by
mailing a copy thereof by registered mail, or a form of mail substantially equivalent thereto, addressed to it at its address as provided for notices hereunder. The Company hereby appoints
[                    ], as its agent for such purposes, and covenants and agrees that service of process in any legal action or proceeding may
be made upon it at such office of such agent. 
 Section 10.12    No Adverse Interpretation of Other
Agreements. This Indenture may not be used to interpret another indenture, loan or debt agreement of the Company or a Subsidiary. Any such indenture, loan or debt agreement may not be used to interpret this Indenture. 

  
 42 













 Section 10.13    Successors. All agreements of the Company
in this Indenture and the Securities shall bind its successor. All agreements of the Trustee in this Indenture shall bind its successor. 

Section 10.14    Severability. In case any provision in this Indenture or in the Securities shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

Section 10.15    Table of Contents, Headings, Etc. The Table of Contents, Cross Reference Table, and headings
of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof. 

Section 10.16    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 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 10.16, “Market Exchange Rate” shall mean the noon Dollar buying rate in New York City for cable transfers of that currency as published by the Federal Reserve Bank of New York; 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, 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 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 Company, 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, be conclusive to the extent permitted by law for all purposes and irrevocably binding upon the Company and all Holders. 

  
 43 













 Section 10.17    Judgment Currency. 

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

Section 10.18    Compliance with Applicable Anti-Terrorism and Money Laundering Regulations. In order to
comply with the laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including those relating to the funding of terrorist activities and money laundering (“Applicable Law”),
the Trustee is required to obtain, verify and record certain information relating to individuals and entities which maintain a business relationship with the Trustee. Accordingly, each of the parties agree to provide to the Trustee, upon its request
from time to time such identifying information and documentation as may be available for such party in order to enable the Trustee to comply with the Applicable Law. 

ARTICLE XI 
 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. 
 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


  
 44 













 
“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 Company 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 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 Registrar, together with an Officers’ Certificate with respect thereto, not later than [    ] days
prior to the date on which the Registrar begins the process of selecting Securities for redemption, and shall be credited for such purpose by the Registrar 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 $[    ], the Registrar 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 Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the 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 Paying Agent upon delivery by the Company to the Registrar 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 11.03    Redemption of Securities for Sinking Fund. Not less than
[    ] days (unless otherwise indicated in the Board Resolution, supplemental indenture hereto 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 and the Paying Agent 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 Company shall thereupon be obligated to pay the amount therein specified. Not less than [    ] 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 3.02 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 3.03. Such notice having been duly given, the
redemption of such Securities shall stated in Sections 3.04, 3.05 and 3.06.
