authentication of Securities by the Trustee) must be delivered only once prior to the authentication and delivery of the first Security of such series; provided, however, that any subsequent order by the Company to the Trustee to authenticate
Securities of such series upon original issuance shall constitute a representation and warranty by the Company that, as of the date of such request, the statements made in any Officers’ Certificate delivered pursuant to this Section 3.3

nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instruction and (iv) shall bear a legend substantially to the following effect: 
 “Unless and until it is exchanged in whole or in part for the individual Securities represented hereby, this Global Security may not be transferred

successor Depositary.”

respect to any Global Security held on their behalf by the Depositary or by the Security Custodian under such Global Security, and the Depositary may be treated by the Company, the Trustee, the Paying Agent and the Registrar and any of their agents
as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Paying Agent or the Registrar or any of their agents from giving effect to any
written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Members, the operation of customary practices of the Depositary governing the exercise of the rights of an owner of a
beneficial interest in any Global Security. The registered holder of a Global Security may grant proxies and otherwise authorize any Person, including Members and Persons that may hold interests through Members, to take any action that a holder is
entitled to take under this Indenture or the Securities. 
 (j) No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in one of the forms provided for herein duly executed by the Trustee by manual signature of one of its Responsible Officers or by
an Authenticating Agent, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

deliver, temporary Securities that are printed, lithographed, typewritten, mimeographed or otherwise reproduced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered
form and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Any such temporary
Security may be in global form, representing all or a portion of the Outstanding Securities of such series. Every such temporary Security shall be executed by the Company and shall be authenticated and delivered by the Trustee upon the same
conditions and in substantially the same manner, and with the same effect, as the definitive Security or Securities in lieu of which it is issued. 
 (b) If temporary Securities of any series are issued, the Company will cause definitive Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of such temporary Securities at the office or agency of the Company in a Place of Payment for such series, without charge to the holder. Upon
surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of
authorized denominations and of like tenor. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 
 (c) Upon any exchange of a portion of a temporary Global Security for a definitive Global Security or for the individual Securities represented thereby
pursuant to this Section 3.4 or Section 3.6, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount evidenced thereby, whereupon the principal amount of such temporary Global
Security shall be reduced for all purposes by the amount so exchanged and endorsed. 
 Section 3.5. Registrar and Paying Agent.

 (a) The Company will keep, at an office or agency to be maintained by it in a Place of Payment where Registered Securities may be
presented for registration or presented and surrendered for registration of transfer or of exchange, and where Securities of any series that are convertible or exchangeable may be surrendered for conversion or exchange, as applicable (the
“Registrar”), a security register for the registration and the registration of transfer or of exchange of the Registered Securities (the registers maintained in such office and in any other office or agency of the Company in a Place of
Payment being herein sometimes collectively referred to as the “Register”), as in this Indenture provided, which Register shall at 

  

 -15- 








 
all reasonable times be open for inspection by the Trustee. Such Register shall be in written form or in any other form capable of being converted into
written form within a reasonable time. The Company may have one or more co-Registrars; the term “Registrar” includes any co-registrar. 
 (b) The Company shall enter into an appropriate agency agreement with any Registrar or co-Registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall
notify the Trustee of the name and address of each such agent. If the Company fails to maintain a Registrar, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 11.1. The Company or any
Affiliate thereof may act as Registrar, co-Registrar or transfer agent. 
 (c) The Company hereby appoints the Trustee at its Corporate
Trust Office as Registrar in connection with the Securities and this Indenture, until such time as another Person is appointed as such.

any Authenticating Agent shall authenticate and deliver, in the name of the designated transferee, one or more new Registered Securities of the same series for like aggregate principal amount of any authorized denomination or denominations. The
transfer of any Security shall not be valid as against the Company or the Trustee unless registered at the Registrar by the registered holder, or by his, her or its attorney duly authorized in writing. 
 (ii) Notwithstanding any other provision of this Section, unless and until it is exchanged in whole or in part for the individual Securities represented
thereby, a Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to such Depositary
or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. 
 (b) Exchange. 
 (i) At the option of the holder, Registered Securities of any series (other than a Global
Security, except as set forth below) may be exchanged for other Registered Securities of the same series for like aggregate principal amount of any authorized denomination or denominations, upon surrender of the Registered Securities to be exchanged
at the Registrar. 
 (ii) Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities that the holder making the exchange is entitled to receive. 
  

 -16- 








 (c) Exchange of Global Securities for Individual Securities. Except as provided below, owners of
beneficial interests in Global Securities will not be entitled to receive individual definitive Securities. 
 (i) Individual definitive
Securities shall be issued to all owners of beneficial interests in a Global Security in exchange for such interests if: (A) at any time the Depositary for the Securities of a series notifies the Company that it is unwilling or unable to
continue as Depositary for the Securities of such series or if at any time the Depositary for the Securities of such series shall no longer be eligible under Section 3.3(h) and, in each case, a successor Depositary is not appointed by the
Company within 90 days of such notice, or (B) the Company executes and delivers to the Trustee and the Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable. 
 In connection with the exchange of an entire Global Security for individual definitive Securities pursuant to this subsection (c), such Global Security
shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual definitive Securities of such series, will
authenticate and deliver to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of individual definitive Securities of authorized denominations.

 (ii) The owner of a beneficial interest in a Global Security will be entitled to receive an individual Security in exchange for such
interest if an Event of Default has occurred and is continuing. Upon receipt by the Security Custodian and Registrar of instructions from the holder of a Global Security directing the Security Custodian and Registrar to (x) issue one or more
individual Securities in the amounts specified to the owner of a beneficial interest in such Global Security and (y) debit or cause to be debited an equivalent amount of beneficial interest in such Global Security, subject to the rules and
regulations of the Depositary: 
 (A) the Security Custodian and Registrar shall notify the Company and the Trustee of such instructions,
identifying the owner and amount of such beneficial interest in such Global Security; 
 (B) the Company shall promptly execute and the
Trustee, upon receipt of a Company Order for the authentication and delivery of individual Securities of such series, shall authenticate and deliver to such beneficial owner individual Securities in an equivalent amount to such beneficial interest
in such Global Security; and 
 (C) the Security Custodian and Registrar shall decrease such Global Security by such amount in accordance
with the foregoing. In the event that the individual Securities are not issued to each such beneficial owner promptly after the Registrar has received a request from the holder of a Global Security to issue such individual Securities, the Company
expressly acknowledges, with respect to the right of any holder to pursue a remedy pursuant to Section 7.7 hereof, the right of any beneficial holder of Securities to pursue such remedy with respect to the portion of the Global Security that
represents such beneficial holder’s Securities as if such individual Securities had been issued. 
  

 -17- 








 (iii) If specified by the Company pursuant to Section 3.1 with respect to a series of Securities,
the Depositary for such series of Securities may surrender a Global Security for such series of Securities in exchange in whole or in part for individual definitive Securities of such series on such terms as are acceptable to the Company and such
Depositary. Thereupon, the Company shall execute, and the Trustee shall authenticate and deliver, without service charge, 
 (A) to each
Person specified by such Depositary a new individual definitive Security or Securities of the same series, of any authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s
beneficial interest in the Global Security; and 
 (B) to such Depositary a new Global Security in a denomination equal to the difference,
if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of individual definitive Securities delivered to holders thereof. 
 (iv) In any exchange provided for in clauses (i) through (iii), the Company will execute and the Trustee will authenticate and deliver individual
definitive Securities in registered form in authorized denominations. 
 (v) Upon the exchange in full of a Global Security for individual
definitive Securities, such Global Security shall be canceled by the Trustee. Individual Registered Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations
as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Registered Securities to the Persons in whose names such
Registered Securities are so registered. 
 (d) All Securities issued upon any registration of 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 for such registration of transfer or exchange. 
 (e) Every Registered Security presented or surrendered for registration of transfer, or for exchange or payment shall (if so required by the Company,
the Trustee or the Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, the Trustee and the Registrar, duly executed by the holder thereof or by his, her or its
attorney duly authorized in writing. 
 (f) No service charge will be made for any registration of transfer or exchange of Securities;
provided, however, that the Company, the Trustee or the Registrar may require payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of
Securities, other than those expressly provided in this Indenture to be made at the Company’s own expense or without expense or charge to the holders. 
  

 -18- 








 (g) The Company shall not be required to (i) register, transfer or exchange Securities of any
series during a period beginning at the opening of business 15 days before the day of the transmission of a notice of redemption of Securities of such series selected for redemption under Section 4.3 and ending at the close of business on the
day of such transmission, or (ii) register, transfer or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 (h) Prior to the due presentation for registration of transfer or exchange of any Security, the Company, the Trustee, the Paying Agent, the Registrar or
any co-Registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for
all purposes whatsoever, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co-Registrar shall be affected by any notice to the contrary. 
 (i) In case a successor Company (“Successor Company”) has executed an indenture supplemental hereto with the Trustee pursuant to Article XIV, any of the Securities authenticated or delivered pursuant to such
transaction may, from time to time, at the request of the Successor Company, be exchanged for other Securities executed in the name of the Successor Company 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 Company Order of the Successor Company, 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 a Successor Company pursuant to this Section 3.6 in exchange or substitution for or upon registration of transfer of any Securities, such Successor Company, at the
option of the holders but without expense to them, shall provide for the exchange of all Securities at the time Outstanding for Securities authenticated and delivered in such new name. 
 (j) Each holder of a Security agrees to indemnify the Company, the Registrar 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 United States federal or state securities laws. 
 (k) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of
any interest in any Security other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same
to determine substantial compliance as to form with the express requirements hereof. 
 (l) Neither the Trustee nor any agent of the Trustee
shall have any responsibility for any actions taken or not taken by the Depositary.

 (a) If (i) any mutilated Security is surrendered to the Trustee at its Corporate Trust Office or (ii) the Company and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee security or indemnity satisfactory to them to save each of them and any Paying Agent harmless, and neither the
Company nor the Trustee receives notice that such Security has been acquired by a protected purchaser, then the Company shall execute and upon Company Request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Security, a new Security of the same series and of like tenor, form, terms and principal amount, bearing a number not contemporaneously Outstanding. Any new Security authenticated and delivered, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Security, under this Section 3.7(a) shall not gain and shall not lose any interest with respect to any such mutilated, destroyed, lost or stolen Security as a result from such exchange or
substitution. 
 (b) In the case that 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 the amount due on such Security in accordance with its terms. 
 (c) Upon the issuance of any new Security under this Section, the Company, the Registrar or the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in respect thereto and any
other expenses (including the fees and expenses of the Trustee) connected therewith. 
 (d) Every new Security of any series issued pursuant
to this Section 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. 
 (e) 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 3.8. Payment of Interest; Interest Rights Preserved. 
 (a) The interest on any Registered Security that is payable and is punctually paid or duly provided for on any Interest Payment Date shall be paid to the Person in whose name such Registered Security (or one or more
Predecessor Securities) is registered at the close of business on the Record Date for such interest notwithstanding the cancellation of such Registered Security upon any transfer or exchange subsequent to the Record Date. Payment of interest on
Registered Securities shall be made at the Corporate Trust Office (except as otherwise specified pursuant to Section 3.1) or, at the option of the Company, by check mailed to the address of the Person entitled thereto as such address shall
appear in the Register or, if provided pursuant to Section 3.1 and in accordance with arrangements satisfactory to the Trustee, at the option of the Registered Holder by wire transfer to an account designated by the Registered Holder.

 (b) Any interest on any Security that is payable but is not punctually paid or duly provided for on any Interest Payment Date (herein
called “Defaulted Interest”) shall, 

  

 -20- 








 
if such Security is a Registered Security, forthwith cease to be payable to the Registered Holder on the relevant Record Date by virtue of his, her or its
having been such a Registered Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 
 (i) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names such Registered Securities (or their respective
Predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Interest (a “Special Record Date”), which shall be fixed in the following manner. The Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Registered Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 calendar days and not less than
10 calendar days prior to the date of the proposed payment and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the holders of such Registered Securities at their
addresses as they appear in the Register, not less than 10 calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names such Registered Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the
following clause (ii). 
 (ii) The Company may make payment of any Defaulted Interest on Registered Securities in any other lawful manner
not inconsistent with the requirements of any securities exchange on which such Registered Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed
payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 (c) Subject to the provisions set
forth herein relating to Record Dates, each Security delivered pursuant to any provision of this Indenture in exchange or substitution for, or upon registration of transfer of, any other Security shall carry all the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security. 
 Section 3.9. Cancellation. Unless otherwise specified pursuant to
Section 3.1 for Securities of any series, all Securities surrendered for payment, redemption, registration of transfer or exchange or credit against any sinking fund or otherwise shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee for cancellation and shall be promptly canceled by it and, if surrendered to the Trustee, shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously
authenticated 

  

 -21- 








 
and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. The Trustee shall dispose of all canceled Securities held by it in
accordance with its then customary procedures and deliver a certificate of such disposal to the Company. The acquisition of any Securities by the Company shall not operate as a redemption or satisfaction of the Indebtedness represented thereby
unless and until such Securities are surrendered to the Trustee for cancellation. 
 Section 3.10. Computation of Interest. Except as
otherwise specified pursuant to Section 3.1 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 
 Section 3.11. Currency of Payments in Respect of Securities. 
 (a) Except as otherwise specified pursuant to Section 3.1 for Registered Securities of any series, payment of the principal of and premium, if any, and interest on Registered Securities of such series will be
made in U.S. Dollars. 
 (b) For purposes of any provision of the Indenture where the holders of Outstanding Securities may perform an
action that requires that a specified percentage of the Outstanding Securities of all series perform such action and for purposes of any decision or determination by the Trustee of amounts due and unpaid for the principal of and premium, if any, and
interest on the Securities of all series in respect of which moneys are to be disbursed ratably, the principal of and premium, if any, and interest on the Outstanding Securities denominated in a Foreign Currency will be the amount in U.S. Dollars
based upon exchange rates, determined as specified pursuant to Section 3.1 for Securities of such series, as of the date for determining whether the holders entitled to perform such action have performed it or as of the date of such decision or
determination by the Trustee, as the case may be. 
 (c) Any decision or determination to be made regarding exchange rates shall be made by
an agent appointed by the Company; provided, that such agent shall accept such appointment in writing and the terms of such appointment shall, in the opinion of the Company at the time of such appointment, require such agent to make such
determination by a method consistent with the method provided pursuant to Section 3.1 for the making of such decision or determination. All decisions and determinations of such agent regarding exchange rates shall be in its sole discretion and
shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Company, the Trustee and all holders of the Securities. 
 Section 3.12. Judgments. The Company may provide pursuant to Section 3.1 for Securities of any series that (a) the obligation, if any, of the Company to pay the principal of, premium, if any, and
interest on the Securities of any series in a Foreign Currency or U.S. Dollars (the “Designated Currency”) as may be specified pursuant to Section 3.1 is of the essence and agrees that, to the fullest extent possible under applicable
law, judgments in respect of such Securities shall be given in the Designated Currency; (b) the obligation of the Company to make payments in the Designated Currency of the principal of and premium, if any, and 

  

 -22- 








 
interest on such Securities shall, notwithstanding any payment in any other Currency (whether pursuant to a judgment or otherwise), be discharged only to the
extent of the amount in the Designated Currency that the holder receiving such payment may, in accordance with normal banking procedures, purchase with the sum paid in such other Currency (after any premium and cost of exchange) on the business day
in the country of issue of the Designated Currency or in the international banking community (in the case of a composite currency) immediately following the day on which such holder receives such payment; (c) if the amount in the Designated
Currency that may be so purchased for any reason falls short of the amount originally due, the Company shall pay such additional amounts as may be necessary to compensate for such shortfall; and (d) any obligation of the Company not discharged
by such payment shall be due as a separate and independent obligation and, until discharged as provided herein, shall continue in full force and effect. 
 Section 3.13. CUSIP Numbers. The Company in issuing any Securities may use CUSIP numbers, if then generally in use, and thereafter with respect to such series, the Trustee may use such numbers in any notice of
redemption or exchange with respect to such series 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 identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of
any change in the CUSIP numbers. 
 ARTICLE IV 
 REDEMPTION OF SECURITIES 
 Section 4.1. Applicability of Right of Redemption.
Redemption of Securities (other than pursuant to a sinking fund or analogous provision) permitted by the terms of any series of Securities shall be made in accordance with such terms (except as otherwise specified pursuant to Section 3.1 for
Securities of any series) in accordance with this Article; provided, however, that if any such terms of a series of Securities shall conflict with any provision of this Article, the terms of such series shall govern. 
 Section 4.2. Selection of Securities to be Redeemed. 
 (a) If the Company shall at any time elect to redeem all or any portion of the Securities of a series then Outstanding, it shall at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter
period shall be satisfactory to the Trustee) notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed, and thereupon the Trustee shall select by lot, or in such manner as the Trustee shall deem appropriate
and fair, the Securities (or portions thereof) of such series to be redeemed. Unless otherwise provided in the Officers’ Certificate or supplemental indenture provided for in Section 3.1, no Security of a denomination of $1,000 shall be
redeemed in part and Securities may be redeemed in part only in integral multiples of $1,000. In any case where more than one Registered Security of such series is registered in the same name, the Trustee in its discretion may treat the aggregate
principal amount so registered as if it were represented by one Registered Security of such series. The Trustee shall, as soon as practicable, notify the Company in writing of the Securities and portions of Securities so selected. 
  

 -23- 








 (b) For all purposes of this Indenture, unless the context otherwise requires, all provisions relating
to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security that has been or is to be redeemed. 
 Section 4.3. Notice of Redemption. 
 (a) The election of the Company to redeem any Securities of any series shall be evidenced by a Board Resolution. Notice of redemption shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the
expense of the Company, not less than 30 nor more than 60 days prior to the Redemption Date, to the holders of Securities of any series to be redeemed in whole or in part pursuant to this Article, in the manner provided in Section 16.6. Any
notice so given shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. Failure to give such notice, or any defect in such notice to the holder of any Security of a series designated for redemption, in
whole or in part, shall not affect the sufficiency of any notice of redemption with respect to the holder of any other Security of such series. 
 (b) All notices of redemption shall identify the Securities to be redeemed (including CUSIP numbers) and shall state: 
 (i) such
election by the Company to redeem Securities of such series pursuant to provisions contained in this Indenture or the terms of the Securities of such series or a supplemental indenture establishing such series, if such be the case; 
 (ii) the Redemption Date; 
 (iii) the
Redemption Price; 
 (iv) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of
partial redemption, the principal amounts) of the particular Securities to be redeemed; 
 (v) that on the Redemption Date the Redemption
Price will become due and payable upon each such Security to be redeemed, and that interest thereon, if any, shall cease to accrue on and after said date; 
 (vi) the Place or Places of Payment where such Securities are to be surrendered for payment of the Redemption Price, and that the Securities designated in such notice for redemption are required to be presented on or
after such Redemption Date at the designated Place of Payment; 
 (vii) that the redemption is for a sinking fund, if such is the case; and

  

 -24- 








 (viii) if any Security of any series is to be redeemed in part, that on and after the Redemption Date,
upon surrender of such Security, such Security will be canceled and a new Security or Securities of such series in aggregate principal amount equal to the unredeemed portion thereof will be issued and delivered without charge to the holder or, in
the case of Securities providing appropriate space for such notation, at the option of the holders, the Trustee, in lieu of delivering a new Security or Securities as aforesaid, may make a notation on such Security of the payment of the redeemed
portion thereof. 
 Section 4.4. Deposit of Redemption Price. On or prior to 10:00 a.m., New York City time, on the Redemption Date
for any Registered Securities, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 6.3) an amount of money in the Currency
in which such Securities are denominated (except as provided pursuant to Section 3.1) sufficient to pay the Redemption Price of such Securities or any portions thereof that are to be redeemed on that date. 
 Section 4.5. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, any Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price and from and after such date (unless the Company shall Default in the payment of the Redemption Price) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price; provided, however, that installments of interest that have a Stated Maturity on or prior to the Redemption Date for such
Securities shall be payable according to the terms of such Securities and the provisions of Section 3.8. 
 If any Security called for
redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
 Section 4.6. Securities Redeemed in Part. Any Security that is to be redeemed only in part shall be surrendered at the Corporate Trust Office or
such other office or agency of the Company as is specified pursuant to Section 3.1 with, if the Company, the Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company, the
Registrar and the Trustee duly executed by the holder thereof or his, her or its attorney duly authorized in writing, and the Company shall execute, and the Trustee shall authenticate and deliver to the holder of such Security without service
charge, a new Security or Securities of the same series, of like tenor and form, of any authorized denomination as requested by such holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the
Security so surrendered; except that if a Global Security is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the Depositary for such Global Security, without service charge, a new Global Security in a
denomination equal to and in exchange for the unredeemed portion of the principal of the Global Security so surrendered. In the case of a Security providing appropriate space for such notation, at the option of the holder thereof, the Trustee, in
lieu of delivering a new Security or Securities as aforesaid, may make a notation on such Security of the payment of the redeemed portion thereof.

 ARTICLE V 
 SINKING FUNDS 
 Section 5.1. Applicability of Sinking Fund. 
 (a) Redemption of Securities permitted or required pursuant to a sinking fund for the retirement of Securities of a series by the terms of such series of
Securities shall be made in accordance with such terms of such series of Securities and this Article, except as otherwise specified pursuant to Section 3.1 for Securities of such series, provided, however, that if any such terms of a series of
Securities shall conflict with any provision of this Article, the terms of such series shall govern. 
 (b) The minimum amount of any
sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “Mandatory Sinking Fund Payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series
is herein referred to as an “Optional Sinking Fund Payment.” If provided for by the terms of Securities of any series, the cash amount of any Mandatory Sinking Fund Payment may be subject to reduction as provided in Section 5.2.

 Section 5.2. Mandatory Sinking Fund Obligation. The Company may, at its option, satisfy any Mandatory Sinking Fund Payment
obligation, in whole or in part, with respect to a particular series of Securities by (1) delivering to the Trustee Securities of such series in transferable form theretofore purchased or otherwise acquired by the Company or redeemed at the
election of the Company pursuant to Section 4.3 or (2) receiving credit for Securities of such series (not previously so credited) acquired by the Company and theretofore delivered to the Trustee. The Trustee shall credit such Mandatory
Sinking Fund Payment obligation with an amount equal to the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such Mandatory Sinking Fund Payment shall be reduced accordingly. If the
Company shall elect to so satisfy any Mandatory Sinking Fund Payment obligation, it shall deliver to the Trustee not less than 45 days prior to the relevant sinking fund payment date a written notice signed on behalf of the Company by its Chairman
of the Board of Directors, its President, one of its Vice Presidents, its Treasurer or one of its Assistant Treasurers, which shall designate the Securities (and portions thereof, if any) so delivered or credited and which shall be accompanied by
such Securities (to the extent not theretofore delivered) in transferable form. In case of the failure of the Company, at or before the time so required, to give such notice and deliver such Securities the Mandatory Sinking Fund Payment obligation
shall be paid entirely in moneys. 
 Section 5.3. Optional Redemption at Sinking Fund Redemption Price. In addition to the sinking
fund requirements of Section 5.2, to the extent, if any, provided for by the terms of a particular series of Securities, the Company may, at its option, make an Optional Sinking Fund Payment with respect to such Securities. Unless otherwise
provided by such terms, (a) to the extent that the right of the Company to make such Optional Sinking Fund Payment shall not be exercised in any year, it shall not be cumulative or carried forward to any subsequent year, and (b) such
optional payment shall operate to reduce the amount of any Mandatory Sinking Fund Payment obligation as to Securities of the same series. If the Company intends to exercise its right to make such optional payment in any year it shall deliver to the


  

 -26- 








 
Trustee not less than 45 days prior to the relevant sinking fund payment date a certificate signed by its Chairman of the Board of Directors, its President,
one of its Vice Presidents, its Treasurer or one of its Assistant Treasurers stating that the Company will exercise such optional right, and specifying the amount which the Company will pay on or before the next succeeding sinking fund payment date.
Such certificate shall also state that no Event of Default has occurred and is continuing. 
 Section 5.4. Application of Sinking Fund
Payment. 
 (a) If the sinking fund payment or payments made in funds pursuant to either Section 5.2 or 5.3 with respect to a
particular series of Securities plus any unused balance of any preceding sinking fund payments made in funds with respect to such series shall exceed $50,000 (or a lesser sum if the Company shall so request, or such equivalent sum for Securities
denominated other than in U.S. Dollars), it shall be applied by the Trustee on the sinking fund payment date next following the date of such payment, unless the date of such payment shall be a sinking fund payment date, in which case such payment
shall be applied on such sinking fund payment date, to the redemption of Securities of such series at the redemption price specified in Section 4.3(b). The Trustee shall select, in the manner provided in Section 4.2, for redemption on such
sinking fund payment date, a sufficient principal amount of Securities of such series to absorb said funds, as nearly as may be, and shall, at the expense and in the name of the Company, thereupon cause notice of redemption of the Securities to be
given in substantially the manner provided in Section 4.3(a) for the redemption of Securities in part at the option of the Company, except that the notice of redemption shall also state that the Securities are being redeemed for the sinking
fund. Any sinking fund moneys not so applied by the Trustee to the redemption of Securities of such series shall be added to the next sinking fund payment received in funds by the Trustee and, together with such payment, shall be applied in
accordance with the provisions of this Section 5.4. Any and all sinking fund moneys held by the Trustee on the last sinking fund payment date with respect to Securities of such series, and not held for the payment or redemption of particular
Securities of such series, shall be applied by the Trustee to the payment of the principal of the Securities of such series at maturity. 
 (b) On or prior to each sinking fund payment date, the Company shall pay to the Trustee a sum equal to all interest accrued to the date fixed for redemption on Securities to be redeemed on such sinking fund payment date pursuant to this
Section 5.4. 
 (c) The Trustee shall not redeem any Securities of a series with sinking fund moneys or mail any notice of redemption
of Securities of such series by operation of the sinking fund during the continuance of a Default in payment of interest on any Securities of such series or of any other Event of Default (other than an Event of Default occurring as a consequence of
this paragraph) of which a Responsible Officer of the Trustee has actual knowledge, except that if the notice of redemption of any Securities of such series shall theretofore have been mailed in accordance with the provisions hereof, the Trustee
shall redeem such Securities if funds sufficient for that purpose shall be deposited with the Trustee in accordance with the terms of this Article. Except as aforesaid, any moneys in the sinking fund at the time any such Default or Event of Default
shall occur and any moneys thereafter paid into the sinking fund shall, during the continuance of such Default or Event of Default, be held as security for the payment of all the Securities of such series; provided, however, that in case such


  

 -27- 








 
Default or Event of Default shall have been cured or waived as provided herein, such moneys shall thereafter be applied on the next sinking fund payment date
on which such moneys are required to be applied pursuant to the provisions of this Section 5.4. 
 ARTICLE VI 
 PARTICULAR COVENANTS OF THE COMPANY 
 The Company hereby covenants and agrees as follows: 
 Section 6.1. Payments of Securities. The Company will duly and
punctually pay the principal of and premium, if any, on each series of Securities, and the interest which shall have accrued thereon, at the dates and place and in the manner provided in the Securities and in this Indenture. 
 Section 6.2. Paying Agent. 
 (a) The
Company will maintain in each Place of Payment for any series of Securities, if any, an office or agency where Securities may be presented or surrendered for payment, where Securities of such series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served (the “Paying Agent”). The Company will give prompt written notice to the Trustee of the location, and any change in
the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as Paying Agent to receive all presentations, surrenders, notices and demands. 
 (b) The Company may also from time to time designate different or additional offices or agencies where the Securities of any series may be presented or
surrendered for any or all such purposes (in or outside of such Place of Payment), and may from time to time rescind any such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its
obligations described in the preceding paragraph. The Company will give prompt written notice to the Trustee of any such additional designation or rescission of designation and of any change in the location of any such different or additional office
or agency. The Company shall enter into an appropriate agency agreement with any Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the
Trustee of the name and address of each such agent. The Company or any Affiliate thereof may act as Paying Agent. 
 Section 6.3. To Hold
Payment in Trust. 
 (a) If the Company or an Affiliate thereof shall at any time act as Paying Agent with respect to any series of
Securities, then, on or before the date on which the principal of and premium, if any, or interest on any of the Securities of that series by their terms or as a result of the calling thereof for redemption shall become payable, the Company or such
Affiliate will segregate and hold in trust for the benefit of the holders of such Securities or the 

  

 -28- 








 
Trustee a sum sufficient to pay such principal and premium, if any, or interest which shall have so become payable until such sums shall be paid to such
holders or otherwise disposed of as herein provided, and will notify the Trustee of its action or failure to act in that regard. Upon any proceeding under any federal bankruptcy laws with respect to the Company or any Affiliate thereof, if the
Company or such Affiliate is then acting as Paying Agent, the Trustee shall replace the Company or such Affiliate as Paying Agent. 
 (b) If
the Company shall appoint, and at the time have, a Paying Agent for the payment of the principal of and premium, if any, or interest on any series of Securities, then prior to 10:00 a.m., New York City time, on the date on which the principal of and
premium, if any, or interest on any of the Securities of that series shall become payable as aforesaid, whether by their terms or as a result of the calling thereof for redemption, the Company will deposit with such Paying Agent a sum sufficient to
pay such principal and premium, if any, or interest, such sum to be held in trust for the benefit of the holders of such Securities or the Trustee, and (unless such Paying Agent is the Trustee), the Company or any other obligor of such Securities
will promptly notify the Trustee of its payment or failure to make such payment. 
 (c) If the Paying Agent shall be other than the Trustee,
the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 6.3, that such Paying Agent shall: 
 (i) hold all moneys held by it for the payment of the principal of and premium, if any, or interest on the Securities of that series in trust for the
benefit of the holders of such Securities until such sums shall be paid to such holders or otherwise disposed of as herein provided; 
 (ii)
give to the Trustee notice of any Default by the Company or any other obligor upon the Securities of that series in the making of any payment of the principal of and premium, if any, or interest on the Securities of that series; and 
 (iii) at any time during the continuance of any such Default, upon the written request of the Trustee, pay to the Trustee all sums so held in trust by
such Paying Agent. 
 (d) Anything in this Section 6.3 to the contrary notwithstanding, the Company may at any time, for the purpose of
obtaining a release, satisfaction or discharge of this Indenture or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or by any Paying Agent other than the Trustee as required by this
Section 6.3, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent. 
 (e) Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and premium, if any, or interest on any Security of any series and remaining
unclaimed for two years after such principal and premium, if any, or interest has become due and payable shall be paid to the Company upon 

  

 -29- 








 
Company Request along with any interest that has accumulated thereon as a result of such money being invested at the direction of the Company, or (if then
held by the Company) shall be discharged from such trust, and the holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment of such amounts without interest thereon, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent before being required to make any such repayment, may
at the expense of the Company cause to be transmitted in the manner and to the extent provided by Section 16.6, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the
date of such mailing, any unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 6.4. Merger,
Consolidation and Sale of Assets. 
 (a) The Company will not consolidate with any other entity or accept a merger of any other entity
into the Company or permit the Company to be merged into any other entity, or sell, other than for cash, all or substantially all of its assets to another entity, or lease all or substantially all of its assets to another entity, or purchase all or
substantially all of the assets of another entity, unless (i) either the Company shall be the continuing entity, or the successor, transferee or lessee entity (if other than the Company) shall expressly assume, by indenture supplemental hereto
satisfactory to the Trustee, executed and delivered by such entity prior to or simultaneously with such consolidation, merger, sale or lease, the due and punctual payment of the principal of and interest and premium, if any, on all the Securities,
according to their tenor, and the due and punctual performance and observance of all other obligations to the holders and the Trustee under this Indenture or under the Securities to be performed or observed by the Company; and (ii) immediately
after such consolidation, merger, sale, lease or purchase the Company or the successor, transferee or lessee entity (if other than the Company) would not be in Default in the performance of any covenant or condition of this Indenture. A purchase by
a Subsidiary of all or substantially all of the assets of another entity shall not be deemed to be a purchase of such assets by the Company. 
 (b) Upon any consolidation with or merger into any other entity, or any sale, other than for cash, of all or substantially all of its assets to another entity, or any conveyance or lease of all or substantially all of the assets of the
Company in accordance with this Section 6.4, the successor entity formed by such consolidation or into or with which the Company is merged or to which the Company is sold or to which such conveyance, transfer or lease 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 entity had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor
Company shall be relieved of all obligations and covenants under this Indenture and the Securities, and from time to time such entity may exercise each and every right and power of the Company under this Indenture, in the name of the Company, or in
its own name; and any act or proceeding by any provision of this Indenture required or permitted to be done by the Board of Directors or any officer of the Company may be done with like force and effect by the like board or officer of any entity
that shall at the time be the successor of the Company hereunder. In the event of any such sale or conveyance, but not any such lease, the Company (or any successor entity which shall theretofore have become such in the manner described in this
Section 6.4) shall be discharged from all obligations and covenants under this Indenture and the Securities and may thereupon be dissolved and liquidated.

days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company’s compliance with all conditions and
covenants under this Indenture (which compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture) and, in the event of any Default, specifying each such Default and the nature and
status thereof of which such person may have knowledge. Such certificates need not comply with Section 16.1 of this Indenture. 
 Section 6.6. Conditional Waiver by Holders of Securities. Anything in this Indenture to the contrary notwithstanding, the Company may fail or omit in any particular instance to comply with a covenant or condition set forth herein
with respect to any series of Securities if the Company shall have obtained and filed with the Trustee, prior to the time of such failure or omission, evidence (as provided in Article VIII) of the consent of the holders of a majority in aggregate
principal amount of the Securities of such series at the time Outstanding, either waiving such compliance in such instance or generally waiving compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, or impair any right consequent thereon and, until such waiver shall have become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition
shall remain in full force and effect. 
 Section 6.7. Statement by Officers as to Default. The Company shall deliver to the Trustee

Officers’ Certificate setting forth the details of such Event of Default or Default and the action which the Company proposes to take with respect thereto.

contemplated by Section 3.1) (other than a covenant or agreement which has been expressly included in this Indenture solely for the benefit of a series of Securities other than that series and other than a covenant or agreement a default in the
performance of which is elsewhere in this Section 7.1 specifically addressed), which failure shall not have been remedied, or without provision deemed to be adequate for the remedying thereof having been made, for a period of 90 days after
written notice shall have been given to the Company by the Trustee or shall have been given to the Company and the Trustee by holders of 25% or more in aggregate principal amount of the Securities of such series then Outstanding, specifying such
failure, requiring the Company to remedy the same and stating that such notice is a “Notice of Default” hereunder;

generally as they become due, or the taking of corporate action by the Company in furtherance of any action; or 
 (g) the occurrence of any
other Event of Default with respect to Securities of such series as provided in a supplemental indenture or Officers’ Certificate, if any, applicable to such series of Securities. 
 Section 7.2. Acceleration; Rescission and Annulment. 
 (a) If any one or more of the above-described Events of Default shall happen with respect to Securities of any series at the time Outstanding, then, and in each and every such case, during the continuance of any such
Event of Default, the Trustee or the holders of 25% or more in principal amount of the Securities of such series then Outstanding may (and upon the written request of the holders of a majority in principal amount of such Securities then 

  

 -32- 








 
Outstanding, the Trustee shall) declare the principal (or, if the Securities of that series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of and all accrued but unpaid interest on all the Securities of such series then Outstanding, if not then due and payable, to be due and payable, and upon any such declaration the
same shall become and be immediately due and payable, anything in this Indenture or in the Securities of such series contained to the contrary notwithstanding; provided that no Event of Default with respect to Securities of a series, except with
respect to an Event of Default under subsections (e) and (f) of Section 7.1 and except to the extent otherwise provided in subsection (d) of Section 7.1, shall constitute an Event of Default with respect to Securities of any
other series. Upon payment of such amounts in the Currency in which such Securities are denominated (except as otherwise provided pursuant to Section 3.1), all obligations of the Company in respect of the payment of principal of and interest on
the Securities of such series shall terminate. 
 (b) Section 7.2(a), however, is subject to the condition that, if at any time after
the principal of all the Securities of such series, to which any one or more of the above-described Events of Default is applicable, shall have been so declared to be due and payable, and before a judgment or decree for payment of the money due has
been obtained by the Trustee as hereinafter in this Article provided, 
 (i) the Company has paid or deposited with the Paying Agent a sum in
the Currency in which such Securities are denominated (except as otherwise provided pursuant to Section 3.1) sufficient to pay 
 (A)
all amounts owing the Trustee and any predecessor trustee hereunder, including, without limitation, Section 11.1(a) (provided, however, that all sums payable under this clause (A) shall be paid in U.S. Dollars); 
 (B) all arrears of interest, if any, upon all the Securities of such series (with interest, to the extent that interest thereon shall be legally
enforceable, on any overdue installment of interest at the rate borne by the Securities); 
 (C) the principal of and premium, if any, on
any Securities of such series that have become due otherwise than by such declaration of acceleration and interest thereon; and 
 (D) all
other sums payable under this Indenture (except the principal of the Securities of such series which would not be due and payable were it not for such declaration); and 
 (ii) every other Default and Event of Default under this Indenture shall have been resolved so that the conditions that caused such Default or Event of Default are no longer outstanding or have otherwise been remedied
to the reasonable satisfaction of the holders of a majority in principal amount of the Securities of such series then Outstanding, or provision deemed by such holders to be adequate therefor shall have been made, then and in every such case the
holders of a majority in principal amount of the Securities of such series then Outstanding may, by written notice to the Company and the 

  

 -33- 








 
Trustee, on behalf of the holders of all the Securities of such series, waive the Event of Default by reason of which the principal of the Securities of such
series shall have been so declared to be due and payable and may rescind and annul such declaration and its consequences; provided, however, that no such waiver, rescission or annulment shall extend to or affect any subsequent Default or Event of
Default or impair any right consequent thereon. 
 (c) Any declaration by the Trustee pursuant to this Section 7.2 shall be by written
notice to the Company, and any declaration or waiver by the holders of Securities of any series pursuant to this Section 7.2 shall be by written notice to the Company and the Trustee. 
 (d) For all purposes under this Indenture, if a portion of the principal of any Discount Securities shall have been accelerated and declared due and
payable pursuant to the provisions hereof, then, from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such Discount Securities shall be deemed, for all purposes hereunder, to be such
portion of the principal thereof as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and payable as a result of such acceleration, together with interest, if any, thereon
and all other amounts owing thereunder, shall constitute payment in full of such Discount Securities. 
 (e) The Company and the Trustee
may, to the extent provided in Section 14.1, enter into one or more indentures supplemental hereto with respect to any series of the Securities which may provide for additional or different Events of Default with respect to such series of
Securities. 
 Section 7.3. Other Remedies. If the Company shall fail for a period of 30 days to pay any installment of interest on
the Securities of any series or shall fail to pay the principal of and premium, if any, on any of the Securities of such series when and as the same shall become due and payable, whether at Maturity, or by call for redemption (other than pursuant to
the sinking fund), by declaration as authorized by this Indenture, or otherwise, or shall fail for a period of 30 days to make any sinking fund payment as to a series of Securities, then, upon demand of the Trustee, the Company will pay to the
Paying Agent for the benefit of the holders of Securities of such series then Outstanding the whole amount which then shall have become due and payable on all the Securities of such series, with interest on the overdue principal and premium, if any,
and (so far as the same may be legally enforceable) on the overdue installments of interest at the rate borne by the Securities of such series, and all amounts owing the Trustee and any predecessor trustee hereunder, including, without limitation,
under Section 11.1(a). 
 In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name
and as trustee of an express trust, shall be entitled and empowered to institute any action or proceeding at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final
decree, and may enforce any such judgment or final decree against the Company or any other obligor upon the Securities of such series, and collect the moneys adjudged or decreed to be payable out of the property of the Company or any other obligor
upon the Securities of such series, wherever situated, in the manner provided by law. Every recovery of judgment in any such action or other proceeding, subject to the payment to the Trustee of all amounts owing the Trustee and any predecessor
trustee hereunder, including, without limitation, under Section 11.1(a), shall be for 

  

 -34- 








 
the ratable benefit of the holders of such series of Securities which shall be the subject of such action or proceeding. All rights of action upon or under
any of the Securities or this Indenture may be enforced by the Trustee without the possession of any of the Securities and without the production of any thereof at any trial or any proceeding relative thereto. 
 Section 7.4. Trustee as Attorney-in-Fact. The Trustee is hereby appointed, and each and every holder of the Securities, by receiving and holding
the same, shall be conclusively deemed to have appointed the Trustee, the true and lawful attorney-in-fact of such holder, with authority to make or file (whether or not the Company shall be in Default in respect of the payment of the principal of,
or interest on, any of the Securities), in its own name and as trustee of an express trust or otherwise as it shall deem advisable, in any receivership, insolvency, liquidation, bankruptcy, reorganization or other judicial proceeding relative to the
Company or any other obligor upon the Securities or to their respective creditors or property, any and all claims, proofs of claim, proofs of debt, petitions, consents, other papers and documents and amendments of any thereof, as may be necessary or
advisable in order to have the claims of the Trustee and any predecessor trustee hereunder and of the holders of the Securities allowed in any such proceeding and to collect and receive any moneys or other property payable or deliverable on any such
claim, and to execute and deliver any and all other papers and documents and to do and perform any and all other acts and things, as it may deem necessary or advisable in order to enforce in any such proceeding any of the claims of the Trustee and
any predecessor trustee hereunder and of any of such holders in respect of any of the Securities; and any receiver, assignee, trustee, custodian or debtor in any such proceeding is hereby authorized, and each and every taker or holder of the
Securities, by receiving and holding the same, shall be conclusively deemed to have authorized any such receiver, assignee, trustee, custodian or debtor, to make any such payment or delivery only to or on the order of the Trustee, and to pay to the
Trustee any amount due it and any predecessor trustee hereunder, including, without limitation, under Section 11.1(a); provided, however, that nothing herein contained shall be deemed to authorize or empower the Trustee to consent to or accept
or adopt, on behalf of any holder of Securities, any plan of reorganization or readjustment affecting the Securities or the rights of any holder thereof, or to authorize or empower the Trustee to vote in respect of the claim of any holder of any
Securities in any such proceeding. 
 Section 7.5. Priorities. Any moneys or properties collected by the Trustee with respect to a
series of Securities under this Article VII shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys or properties and, in the case of the distribution of such moneys or properties on
account of the Securities of any series, upon presentation of the Securities of such series, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First: To the payment of all amounts due to the Trustee and any predecessor trustee hereunder, including, without limitation, under
Section 11.1(a). 
 Second: In case the principal of the Outstanding Securities of such series shall not have become due and be
unpaid, to the payment of interest on the Securities of such series, in the chronological order of the Maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue
installments of interest at the rate borne by such Securities, such payments to be made ratably to the Persons entitled thereto. 
  

 -35- 








 Third: In case the principal of the Outstanding Securities of such series shall have become due,
by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Securities of such series for principal and premium, if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent
that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Securities of such series, and in case such moneys shall be insufficient to pay in full the whole amounts so due and unpaid upon the
Securities of such series, then to the payment of such principal and premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any
installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest. 
 Any surplus then remaining shall be paid to the Company or as directed by a court of competent jurisdiction. 
 Section 7.6. Control by Securityholders; Waiver of Past Defaults. The holders of a majority in principal amount of the Securities of any series at
the time Outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee hereunder, or of exercising any trust or power hereby conferred upon the Trustee with respect to the Securities of such
series, provided, however, that, subject to the provisions of Sections 11.1 and 11.2, the Trustee shall have the right to decline to follow any such direction if the Trustee being advised by counsel determines that the action so directed may not
lawfully be taken or would be unduly prejudicial to holders not joining in such direction or would involve the Trustee in personal liability. Prior to any declaration accelerating the Maturity of the Securities of any series, the holders of a
majority in aggregate principal amount of such series of Securities at the time Outstanding may on behalf of the holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a
Default in the payment of interest or any premium on or the principal of the Securities of such series. Upon any such waiver the Company, the Trustee and the holders of the Securities of such series shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by
this Section 7.6, said Default or Event of Default shall for all purposes of the Securities of such series and this Indenture be deemed to have been cured and to be not continuing. 
 Section 7.7. Limitation on Suits. No holder of any Security of any series shall have any right to institute any action, suit or proceeding at law
or in equity for the execution of any trust hereunder or for the appointment of a receiver or for any other remedy hereunder, in each case with respect to an Event of Default with respect to such series of Securities, unless such holder previously
shall have given to the Trustee written notice of the happening of one or more of the Events of Default herein specified with respect to such series of Securities, and unless also the holders of 25% in principal amount of the Securities of such
series then Outstanding shall have requested the Trustee in writing to take action in respect of the matter 

  

 -36- 








 
complained of, and unless also there shall have been offered to the Trustee security and indemnity satisfactory to it against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee, for 60 days after receipt of such notification, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and such notification,
request and offer of indemnity are hereby declared in every such case to be conditions precedent to any such action, suit or proceeding by any holder of any Security of such series; it being understood and intended that no one or more of the holders
of Securities of such series shall have any right in any manner whatsoever by his, her, its or their action to enforce any right hereunder, except in the manner herein provided, and that every action, suit or proceeding at law or in equity shall be
instituted, had and maintained in the manner herein provided and for the equal benefit of all holders of the Outstanding Securities of such series; provided, however, that nothing in this Indenture or in the Securities of such series shall affect or
impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on the Securities of such series to the respective holders of such Securities at the respective due dates in such
Securities stated, or affect or impair the right, which is also absolute and unconditional, of such holders to institute suit to enforce the payment thereof. 
 Section 7.8. Undertaking for Costs. All parties to this Indenture and each holder of any Security, by such holder’s acceptance thereof, shall be deemed to have agreed that any court may in its discretion
require, in any action, suit or proceeding for the enforcement of any right or remedy under this Indenture, or in any action, suit or proceeding against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant
in such action, suit or proceeding of an undertaking to pay the costs of such action, suit or proceeding, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in
such action, suit or proceeding, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section 7.8 shall not apply to any action, suit or proceeding
instituted by the Trustee, to any action, suit or proceeding instituted by any one or more holders of Securities holding in the aggregate more than 10% in principal amount of the Securities of any series Outstanding, or to any action, suit or
proceeding instituted by any holder of Securities of any series for the enforcement of the payment of the principal of or premium, if any, or the interest on, any of the Securities of such series, on or after the respective due dates expressed in
such Securities. 
 Section 7.9. Remedies Cumulative. No remedy herein conferred upon or reserved to the Trustee or to the holders of
Securities of any series is intended to be exclusive of any other remedy or remedies, and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or by
statute. No delay or omission of the Trustee or of any holder of the Securities of any series to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power or shall be construed to be a waiver of
any such Default or Event of Default or an acquiescence therein; and every power and remedy given by this Article VII to the Trustee and to the holders of Securities of any series, respectively, may be exercised from time to time and as often as may
be deemed expedient by the Trustee or by the holders of Securities of such series, as the case may be. In case the Trustee or any holder of Securities of any series shall have proceeded to enforce any right under this Indenture and the proceedings
for the enforcement 

  

 -37- 








 
thereof shall have been discontinued or abandoned because of waiver or for any other reason or shall have been adjudicated adversely to the Trustee or to
such holder of Securities, then and in every such case the Company, the Trustee and the holders of the Securities of such series shall severally and respectively be restored to their former positions and rights hereunder, and thereafter all rights,
remedies and powers of the Trustee and the holders of the Securities of such series shall continue as though no such proceedings had been taken, except as to any matters so waived or adjudicated. 
 ARTICLE VIII 
 CONCERNING THE
SECURITYHOLDERS 
 Section 8.1. Evidence of Action of Securityholders. Whenever in this Indenture it is provided that the
holders of a specified percentage or a majority in aggregate principal amount of the Securities or of any series of Securities may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the
taking of any other action), the fact that at the time of taking any such action the holders of such specified percentage or majority have joined therein may be evidenced by (a) any instrument or any number of instruments of similar tenor
executed by Securityholders in person or by agent or proxy appointed in writing (such action becoming effective, except as herein otherwise expressly provided, when such instrument or instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Company), or (b) by the record of the holders of Securities voting in favor thereof at any meeting of Securityholders duly called and held in accordance with the provisions of Article VII, or (c) by a combination
of such instrument or instruments and any such record of such a meeting of Securityholders. 
 Section 8.2. Proof of Execution or Holding
of Securities. Proof of the execution of any instrument by a Securityholder or his, her or its agent or proxy and proof of the holding by any Person of any of the Securities shall be sufficient if made in the following manner: 
 (a) The fact and date of the execution by any Person of any such instrument may be proved (i) by the certificate of any notary public or other
officer in any jurisdiction who, by the laws thereof, has power to take acknowledgments or proof of deeds to be recorded within such jurisdiction, that the Person who signed such instrument did acknowledge before such notary public or other officer
the execution thereof, or (ii) by the affidavit of a witness of such execution sworn to before any such notary or other officer. Where such execution is by a Person acting in other than his or her individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his or her authority. 
 (b) The ownership of Registered Securities of any series shall
be proved by the Register of such Securities or by a certificate of the Registrar for such series. 
 (c) The record of any holders’
meeting shall be proved in the manner provided in Section 9.6. 
 (d) The Trustee may require such additional proof of any matter
referred to in this Section 8.2 as it shall deem appropriate or necessary, so long as the request is a reasonable one. 
  

 -38- 








 (e) If the Company shall solicit from the holders of Securities of any series any action, the Company
may, at its option, by Board Resolution, fix in advance a record date for the determination of holders of Registered Securities entitled to take such action, but the Company shall have no obligation to do so. Any such record date shall be fixed at
the Company’s discretion. If such a record date is fixed, such action may be sought or given before or after the record date, but only the holders of Registered Securities of record at the close of business on such record date shall be deemed
to be holders of Registered Securities for the purpose of determining whether holders of the requisite proportion of Outstanding Securities of such series have authorized or agreed or consented to such action, and for that purpose the Outstanding
Registered Securities of such series shall be computed as of such record date. 
 Section 8.3. Persons Deemed Owners. 
 (a) The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of principal of and premium, if any, and interest, if any, on, such Registered Security and for all other purposes whatsoever, whether or not such Registered Security be overdue,
and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. All payments made to any holder, or upon his, her or its order, shall be valid, and, to the extent of the sum or sums paid,
effectual to satisfy and discharge the liability for moneys payable upon such Security. 
 (b) None of the Company, the Trustee, any Paying
Agent or the Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests. 
 Section 8.4. Revocation of Consents. At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 8.1, of the taking of any action by the holders of the percentage in aggregate principal amount of the Securities or of any series of Securities specified in this Indenture in connection with
such action, any holder of a Security which is shown by the evidence to be included in the Securities the holders of which have consented to such action may, by filing written notice with the Trustee at its principal office and upon proof of holding
as provided in Section 8.2, revoke such action so far as concerns such Security. Except as aforesaid, any such action taken by the holder of any Security shall be conclusive and binding upon such holder and upon all future holders of such
Security, and of any Securities issued on transfer or in lieu thereof or in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon such Security or such other Securities or any Security issued
in exchange or substitution therefor.

Persons holding or representing Securities in an aggregate principal amount sufficient to take action upon the business for the transaction of which such meeting was called shall be necessary to constitute a quorum, and any such meeting may be
adjourned from time to time by a majority of those present, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice. 
 Section 9.6. Voting. The vote upon any resolution submitted to any meeting of Securityholders of a series shall be by written ballots on which shall be subscribed the signatures of the holders of Securities of
such series or of their representatives by proxy and the principal amounts of the Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at
the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of
Securityholders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge
of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.2. The record shall show the principal amounts of the Securities voting in favor of or against any resolution. The
record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee. 
 Any record so signed and verified shall be conclusive evidence of the matters therein stated.

conferred upon or reserved to the Trustee or to the Securityholders of such series under any of the provisions of this Indenture or of the Securities of such series.

 ARTICLE XI 
 CONCERNING THE
TRUSTEE 
 Section 11.1. Rights of Trustees; Compensation and Indemnity. The Trustee accepts the trusts created by this
Indenture upon the terms and conditions hereof, including the following, to all of which the parties hereto and the holders from time to time of the Securities agree: 
 (a) The Trustee shall be entitled to such compensation as the Company and the Trustee shall from time to time agree for all services rendered by it hereunder (including in any agent capacity in which it acts). The
compensation of the Trustee shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon its request for all reasonable out-of-pocket expenses,
disbursements and advances incurred or made by the Trustee (including the reasonable expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its gross negligence, bad faith or
willful misconduct. 
 The Company also agrees to indemnify each of the Trustee and any predecessor Trustee hereunder for, and to hold it
harmless against, any and all loss, liability, damage, claim, or expense incurred without its own gross negligence, bad faith or willful misconduct, arising out of or in connection with the acceptance or administration of the trust or trusts
hereunder and the performance of its duties (including in any agent capacity in which it acts), as well as the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers
or duties hereunder. The Trustee shall notify the Company 

  

 -43- 








 
promptly of any claim for which it may seek indemnity; provided, however, that the failure of the Trustee to so notify the Company shall not limit, impair or
diminish the Company’s obligation to indemnify the Trustee for any such claim. The Company shall defend the claim and the Trustee shall cooperate in the defense; provided, however, that the Trustee may have one separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 
 As security for the performance of the obligations of the Company under this Section 11.1(a), the Trustee shall have a lien therefor on any moneys
or properties held by the Trustee hereunder to the extent of such obligations. Notwithstanding any provisions of this Indenture to the contrary, the obligations of the Company to compensate and indemnify the Trustee under this Section 11.1(a)
shall survive the resignation or removal of the Trustee and any satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in clause (e) or (f) of Section 7.1
occurs, the expenses and compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or similar laws. 
 (b) The Trustee may execute any of the trusts or powers hereof and perform any duty hereunder either directly or by its agents and attorneys and shall
not be responsible for any misconduct or negligence on the part of any agent or attorney appointed in good faith by it hereunder. 
 (c) The
Trustee shall not be responsible in any manner whatsoever for the correctness of the recitals herein or in the Securities (except its certificates of authentication thereon) contained, all of which are made solely by the Company; and the Trustee
shall not be responsible or accountable in any manner whatsoever for or with respect to the validity or execution or sufficiency of this Indenture or of the Securities (except its certificates of authentication thereon), and the Trustee makes no
representation with respect thereto, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and accurate, subject to the qualifications set forth therein. The Trustee shall not be accountable for the use or application by the Company of any Securities, or the proceeds of
any Securities. 
 (d) The Trustee may consult with counsel of its selection, and, to the extent permitted by Section 11.2, any Opinion
of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered by the Trustee hereunder in good faith and in accordance with such Opinion of Counsel. 
 (e) The Trustee, to the extent permitted by Section 11.2, may rely upon the certificate of the Secretary or one of the Assistant Secretaries of the
Company as to the adoption of any resolution by the Board of Directors or stockholders of the Company, and any request, direction, order or demand of the Company mentioned herein shall be sufficiently 

  

 -44- 








 
evidenced by, and whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to
taking, offering or omitting any action hereunder, the Trustee may rely upon, an Officers’ Certificate of the Company (unless other evidence in respect thereof be herein specifically prescribed). 
 (f) Subject to Section 11.4, the Trustee or any agent of the Trustee, in its individual or any other capacity, may become the owner or pledgee of
Securities and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with the Company with the same rights it would have had if it were not the Trustee or such agent. 
 (g) Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company. 
 (h) Any action taken
by the Trustee pursuant to any provision hereof at the request or with the consent of any Person who at the time is the holder of any Security shall be conclusive and binding in respect of such Security upon all future holders thereof or of any
Security or Securities which may be issued for or in lieu thereof in whole or in part, whether or not such Security shall have noted thereon the fact that such request or consent had been made or given. 
 (i) The Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties. 
 (j) The Trustee shall not be under any obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or
direction of any of the holders of the Securities, pursuant to any provision of this Indenture, unless one or more of the holders of the Securities shall have offered to the Trustee security or indemnity satisfactory to it against the costs,
expenses and liabilities which may be incurred by it therein or thereby. 
 (k) The Trustee shall not be liable for any action taken or
omitted by it in good faith and believed by it to be authorized or within its discretion or within the rights or powers conferred upon it by this Indenture. 
 (l) The Trustee shall not be deemed to have knowledge or notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless the holders of not less than 25% of
the Outstanding Securities notify the Trustee thereof. 
 (m) The Trustee shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of Indebtedness or other paper or document, but the Trustee, in its discretion,
may make such further inquiry or investigation into such facts or matters as it may see fit. 
  

 -45- 








 (n) The rights, privileges, protections, immunities and benefits given to the Trustee, including,
without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder. 
 Section 11.2. Duties of Trustee. 
 (a) If one or more of the Events of Default specified in Section 7.1 with respect to
the Securities of any series shall have happened, then, during the continuance thereof, the Trustee shall, with respect to such Securities, exercise such of the rights and powers vested in it by this Indenture, and shall 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 such person’s own affairs. 
 (b) None of the provisions of this Indenture shall be construed as relieving the Trustee from liability for its own grossly negligent action, grossly negligent failure to act, or its own willful misconduct, except that, anything in this
Indenture contained to the contrary notwithstanding, unless and until an Event of Default specified in Section 7.1 with respect to the Securities of any series shall have happened which at the time is continuing, 
 (i) the Trustee undertakes to perform such duties and only such duties with respect to the Securities of that series as are specifically set out in this
Indenture; and 
 (ii) no implied covenants or obligations shall be read into this Indenture against the Trustee, whose duties and
obligations shall be determined solely by the express provisions of this Indenture. 
 (c) The Trustee may conclusively rely, as to the
truth of the statements and the correctness of the opinions expressed therein, in the absence of bad faith on the part of the Trustee, upon certificates and opinions furnished to it pursuant to the express provisions of this Indenture; but in the
case of any such certificates or opinions which, by the provisions of this Indenture, are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 
 (d) The Trustee shall not be liable to any holder of Securities or to any other Person for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was
negligent in ascertaining the pertinent facts. 
 (e) The Trustee shall not be liable to any holder of Securities or to any other Person
with respect to any action taken or omitted to be taken by it in good faith, in 

  

 -46- 








 
accordance with the direction of Securityholders given as provided in this Indenture, relating to the time, method and place of conducting any proceeding for
any remedy available to it or exercising any trust or power conferred upon it by this Indenture. 
 (f) None of the provisions of this
Indenture shall be construed as requiring the Trustee to expend or risk its own funds or otherwise to incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if there shall
be reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
 (g) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of
this Section 11.2. 
 Section 11.3. Notice of Defaults. Within 90 days after the occurrence thereof, and if actually known to a
Responsible Officer of the Trustee, the Trustee shall give to the holders of the Securities of a series notice of each Default or Event of Default with respect to the Securities of such series actually known to a Responsible Officer of the Trustee,
by transmitting such notice to holders at their addresses as the same shall then appear on the Register of the Company, unless such Default shall have been cured before the giving of such notice (the term “Default” being hereby defined to
be the events specified in Section 7.1, which are, or after notice or lapse of time or both would become, Events of Default as defined in said Section). Except in the case of a Default or Event of Default in payment of the principal of,
premium, if any, or interest on any of the Securities of such series when and as the same shall become payable, or to make any sinking fund payment as to Securities of the same series, the Trustee shall be protected in withholding such notice, if
and so long as a Responsible Officer or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the holders of the Securities of such series. 
 Section 11.4. Eligibility; Disqualification. 
 (a) The Trustee shall at all times satisfy the requirements of TIA Section 310(a). The Trustee shall have a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition, and
shall have a Corporate Trust Office. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 11.4, it shall resign immediately in the manner and with the effect hereinafter specified in this
Article. 
 (b) The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of
TIA Section 310(b)(i) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA
Section 310(b)(i) are met. If the Trustee has or shall acquire a conflicting interest within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. If Section 310(b) of the Trust Indenture Act is amended any time after the date of this Indenture to change the circumstances under which a


  

 -47- 








 
Trustee shall be deemed to have a conflicting interest with respect to the Securities of any series or to change any of the definitions in connection
therewith, this Section 11.4 shall be automatically amended to incorporate such changes. 
 Section 11.5. Registration and Notice;
Removal. The Trustee, or any successor to it hereafter appointed, may at any time resign and be discharged of the trusts hereby created with respect to any one or more or all series of Securities by giving to the Company notice in writing and by
mailing notice thereof to the holders of Securities of such series at their addresses as the same shall then appear in the Register of the Company. Such resignation shall take effect upon the appointment of a successor Trustee and the acceptance of
such appointment by such successor Trustee. Any Trustee hereunder may be removed with respect to any series of Securities at any time by the filing with such Trustee and the delivery to the Company of an instrument or instruments in writing signed
by the holders of a majority in principal amount of the Securities of such series then Outstanding, specifying such removal and the date when it shall become effective. 
 If at any time: 
 (1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after
written request therefor by the Company or by any holder who has been a bona fide holder of a Security for at least six months, or 
 (2)
the Trustee shall cease to be eligible under Section 11.4 and shall fail to resign after written request therefor by the Company or by any holder who has been a bona fide holder of a Security for at least six months, or 
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case, (i) the Company, by a Board Resolution or pursuant to an Officers’ Certificate, may remove the Trustee and appoint a successor Trustee with respect to all Securities, or
(ii) subject to TIA Section 315(e), any Securityholder who has been a bona fide holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
 Upon its resignation or
removal, any Trustee shall be entitled to the payment of reasonable compensation for the services rendered hereunder by such Trustee and to the payment of all reasonable expenses incurred hereunder and all moneys then due to it hereunder. The
Trustee’s rights to indemnification provided in Section 11.1(a) shall survive its resignation or removal. 
 Section 11.6.
Successor Trustee by Appointment. 
 (a) In case at any time the Trustee shall resign, or shall be removed (unless the Trustee shall
be removed as provided in Section 11.4(b), in which event the vacancy 

  

 -48- 








 
shall be filled as provided in said subdivision), or shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or if a receiver of the
Trustee or of its property shall be appointed, or if any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation with respect to the Securities of one or
more series, a successor Trustee with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time
there shall be only one Trustee with respect to the Securities of any series) may be appointed by the holders of a majority in principal amount of the Securities of that or those series then Outstanding, by an instrument or instruments in writing
signed in duplicate by such holders and filed, one original thereof with the Company and the other with the successor Trustee; but, until a successor Trustee shall have been so appointed by the holders of Securities of that or those series as herein
authorized, the Company by a resolution of its Board of Directors, or, in case all or substantially all the assets of the Company shall be in the possession of one or more custodians or receivers lawfully appointed, or of trustees in bankruptcy or
reorganization proceedings (including a trustee or trustees appointed under the provisions of the federal bankruptcy laws, as now or hereafter constituted), or of assignees for the benefit of creditors, such receivers, custodians, trustees or
assignees, as the case may be, by an instrument in writing, shall appoint a successor Trustee with respect to the Securities of such series. Subject to the provisions of Sections 11.4 and 11.5, upon the appointment as aforesaid of a successor
Trustee with respect to the Securities of any series, the Trustee with respect to the Securities of such series shall cease to be Trustee hereunder. After any such appointment other than by the holders of Securities of that or those series, the
Person making such appointment shall forthwith cause notice thereof to be mailed to the holders of Securities of such series at their addresses as the same shall then appear on the Register of the Company but any successor Trustee with respect to
the Securities of such series so appointed shall, immediately and without further act, be superseded by a successor Trustee appointed by the holders of Securities of such series in the manner above prescribed, if such appointment be made prior to
the expiration of one year from the date of the mailing of such notice by the Company, or by such receivers, trustees or assignees. 
 (b)
If any Trustee with respect to the Securities of one or more series shall resign because of conflicting interest as provided in Section 11.4(b) and a successor Trustee shall not have been appointed by the Company or by the holders of the
Securities of such series or, if any successor Trustee so appointed shall not have accepted its appointment within 30 days after such appointment shall have been made, the resigning Trustee at the expense of the Company may apply to any court of
competent jurisdiction for the appointment of a successor Trustee. If in any other case a successor Trustee shall not be appointed pursuant to the foregoing provisions of this Section 11.6 within 60 days after such appointment might have been
made hereunder, the holder of any Security of the applicable series or any retiring Trustee at the expense of the Company may apply to any court of competent jurisdiction to appoint a successor Trustee. Such court may thereupon, in any such case,
after such notice, if any, as such court may deem proper and prescribe, appoint a successor Trustee. 
 (c) Any successor Trustee appointed
hereunder with respect to the Securities of one or more series shall execute, acknowledge and deliver to its predecessor Trustee and to the Company, or to the receivers, trustees, assignees or court appointing it, as the case may be, an instrument
accepting such appointment hereunder, and thereupon such successor 

  

 -49- 








 
Trustee, without any further act, deed or conveyance, shall become vested with all the authority, rights, powers, trusts, immunities, duties and obligations
with respect to such series of such predecessor Trustee with like effect as if originally named as Trustee hereunder, and such predecessor Trustee, upon payment of its fees, charges and disbursements then unpaid, shall thereupon become obligated to
pay over, and such successor Trustee shall be entitled to receive, all moneys and properties held by such predecessor Trustee as Trustee hereunder. Nevertheless, on the written request of the Company or of the successor Trustee or of the holders of
at least 10% in principal amount of the Securities of such series then Outstanding, such predecessor Trustee, upon payment of its said fees, charges and disbursements, shall execute and deliver an instrument transferring to such successor Trustee
upon the trusts herein expressed all the rights, powers and trusts of such predecessor Trustee and shall assign, transfer and deliver to the successor Trustee all moneys and properties held by such predecessor Trustee; and, upon request of any such
successor Trustee and the Company shall make, execute, acknowledge and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Trustee all such authority, rights, powers, trusts,
immunities, duties and obligations. 
 Section 11.7. Successor Trustee by Merger. Any corporation into which the Trustee or any
successor to it in the trusts created by this Indenture shall be merged or converted, or any corporation with which it or any successor to it shall be consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee or any such successor to it shall be a party, or any corporation to which the Trustee or any successor to it shall sell or otherwise transfer all or substantially all of the corporate trust business of the Trustee, shall be the successor
Trustee under this Indenture without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided that such corporation shall be otherwise qualified and eligible under this Article. In case at the time
such successor to the Trustee shall succeed to the trusts created by this Indenture with respect to one or more series of Securities, any of such Securities shall have been authenticated but not delivered by the Trustee then in office, any successor
to such Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Securities in the name of any predecessor Trustee shall apply only to
its successor or successors by merger, conversion or consolidation. 
 Section 11.8. Right to Rely on Officers’ Certificate.
Subject to Section 11.2, and subject to the provisions of Section 16.1 with respect to the certificates required thereby, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable
that a matter be proved or established prior to taking or suffering any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence, bad faith or willful misconduct on
the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate with respect thereto delivered to the Trustee, and such Officers’ Certificate, in the absence of negligence, bad faith or willful
misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 
  

 -50- 








 Section 11.9. Appointment of Authenticating Agent. The Trustee may appoint an agent (the
“Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities, and the Trustee shall give written notice of such appointment to all holders of Securities of the series with respect to which such Authenticating
Agent will serve. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by
the Authenticating Agent. Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. 
 Each Authenticating Agent shall at all times be a corporation organized and doing business and in good standing under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State
authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Article XI, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Article
XI, it shall resign immediately in the manner and with the effect specified in this Article XI. 
 Any corporation into which an
Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Article XI, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 11.9, the Trustee may appoint a successor Authenticating Agent which shall be
acceptable to the Company and shall give written notice of such appointment to all holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 11.9. 
  

 -51- 








 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its
services under this Section 11.9, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 11.1. 
 Section 11.10. Communications by Securityholders with Other Securityholders. 
 Holders of Securities
may communicate pursuant to Section 312(b) of the Trust Indenture Act with other holders with respect to their rights under this Indenture or the Securities. The Company, the Trustee, the Registrar and anyone else shall have the protection of
Section 312(c) of the Trust Indenture Act with respect to such communications. 
 ARTICLE XII 
 SATISFACTION AND DISCHARGE; DEFEASANCE 
 Section 12.1. Applicability of Article. If, pursuant to Section 3.1, provision is made for the defeasance of Securities of a series and if the Securities of such series are Registered Securities and denominated and payable only
in U.S. Dollars (except as provided pursuant to Section 3.1), then the provisions of this Article shall be applicable except as otherwise specified pursuant to Section 3.1 for Securities of such series. Defeasance provisions, if any, for
Securities denominated in a Foreign Currency.

in the case of the Securities of such series being Discharged accompanied by a ruling to that effect received from or published by the Internal Revenue Service. 
 “Discharged” means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by, and obligations under, the Securities of such series and to have satisfied all the
obligations under this Indenture relating to the Securities of such series (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except (A) the rights of holders of Securities of such series
to receive, from the trust fund described in clause (a) above, payment of the principal of and premium, if any, and interest on such Securities when such payments are due, (B) the Company’s obligations with respect to Securities of

 Section 12.6. Deposits to Be Held in Escrow. Any deposits with the Trustee referred to in
Section 12.3 above shall be irrevocable (except to the extent provided in Sections 12.4 and 12.7) and shall be made under the terms of an escrow trust agreement in form and substance satisfactory to the Trustee. If any Outstanding Securities of
a series are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any mandatory or optional sinking fund requirement, the applicable escrow trust agreement shall provide therefor
and the Company shall make such arrangements as are satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. The agreement shall provide that, upon satisfaction of any
mandatory sinking fund payment requirements, whether by deposit of moneys, application of proceeds of deposited U.S. Government Obligations or, if permitted, by delivery of Securities, the Trustee shall pay or deliver over to the Company as excess
moneys pursuant to Section 12.4 all funds or obligations then held under the agreement and allocable to the sinking fund payment requirements so satisfied. 
 If Securities of a series with respect to which such deposits are made may be subject to later redemption at the option of the Company or pursuant to optional sinking fund payments, the applicable escrow trust
agreement may, at the option of the Company, provide therefor. In the case of an optional redemption in whole or in part, such agreement shall require the Company to deposit with the Trustee on or before the date notice of redemption is given funds
sufficient to pay the Redemption Price of the Securities to be redeemed together with all unpaid interest thereon to the Redemption Date. Upon such deposit of funds, the Trustee shall pay or deliver over to the Company as excess funds pursuant to
Section 12.4 all funds or obligations then held under such agreement and allocable to the Securities to be redeemed. In the case of exercise of optional sinking fund payment rights by the Company, such agreement shall, at the option of the
Company, provide that upon deposit by the Company with the Trustee of funds pursuant to such exercise the Trustee shall pay or deliver over to the Company as excess funds pursuant to Section 12.4 all funds or obligations then held under such
agreement for such series and allocable to the Securities to be redeemed. 
 Section 12.7. Application of Trust Money. 
 (a) Neither the Trustee nor any other paying agent shall be required to pay interest on any moneys deposited pursuant to the provisions of this
Indenture, except such as it shall agree with the Company to pay thereon. Any moneys so deposited for the payment of the principal of, or premium, if any, or interest on the Securities of any series and remaining unclaimed for two years after the
date of the maturity of the Securities of such series or the date fixed for the redemption of all the Securities of such series at the time outstanding, as the case may be, shall be repaid by the Trustee or such other paying agent to the Company
upon its written request and thereafter, anything in this Indenture to the contrary notwithstanding, any rights of the holders of Securities of such series in respect of which such moneys shall have been deposited shall be enforceable only against
the Company, and all liability of the Trustee or such other paying agent with respect to such moneys shall thereafter cease. 
  

 -55- 








 (b) Subject to the provisions of the foregoing paragraph, any moneys which at any time shall be
deposited by the Company or on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of, premium, if any, and interest on any of the Securities shall be and are hereby assigned, transferred and set over to the
Trustee or such other paying agent in trust for the respective holders of the Securities for the purpose for which such moneys shall have been deposited; but such moneys need not be segregated from other funds except to the extent required by law.

 Section 12.8. Deposits of Non-U.S. Currencies. Notwithstanding the foregoing provisions of this Article, if the Securities of any
series are payable in a Currency other than U.S. Dollars, the Currency or the nature of the government obligations to be deposited with the Trustee under the foregoing provisions of this Article shall be as set forth in the Officers’
Certificate or established in the supplemental indenture under which the Securities of such series are issued. 
 ARTICLE XIII

 IMMUNITY OF CERTAIN PERSONS 
 Section 13.1. No Personal Liability. No recourse shall be had for the payment of the principal of, or the premium, if any, or interest on, any Security or for any claim based thereon or otherwise in respect
thereof or of the Indebtedness represented thereby, or upon any obligation, covenant or agreement of this Indenture, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitutional provision, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed
and understood that this Indenture and the Securities are solely corporate obligations, and that no personal liability whatsoever shall attach to, or be incurred by, any incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, because of the incurring of the Indebtedness hereby authorized or under or by reason of any of the obligations, covenants,
promises or agreements contained in this Indenture or in any of the Securities, or to be implied herefrom or therefrom, and that all liability, if any, of that character against every such incorporator, stockholder, officer and director is, by the
acceptance of the Securities and as a condition of, and as part of the consideration for, the execution of this Indenture and the issue of the Securities expressly waived and released.

limitations or restrictions thereafter to be observed. 
 Subject to the provisions of Section 14.3, the Trustee is authorized to join
with the Company in the execution of any such supplemental indenture, to make the further agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property or assets

 ARTICLE XV 
 SUBORDINATION OF SECURITIES 
 Section 15.1. Agreement to Subordinate. In the event a
series of Securities is designated as subordinated pursuant to Section 3.1(s), and except as otherwise provided in Board Resolutions or a supplemental indenture, the Company, for itself, its successors and assigns, covenants and agrees, and
each holder of Securities of such series by his, her or its acceptance thereof, likewise covenants and agrees, that the payment of the principal of (and premium, if any) and interest, if any, on each and all of the Securities of such series is
hereby expressly subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of all Senior Indebtedness. In the event a series of Securities is not designated as subordinated pursuant to
Section 3.1(s), this Article XV shall have no effect upon the Securities. 
 Section 15.2. Distribution on Dissolution, Liquidation
and Reorganization; Subrogation of Securities. Subject to Section 15.1, upon any distribution of assets of the Company upon any dissolution, winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency,
reorganization or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company or otherwise (subject to the power of a court of competent jurisdiction to make other
equitable provision reflecting the rights conferred in this Indenture upon the Senior Indebtedness and the holders thereof with respect to the Securities and the holders thereof by a lawful plan of reorganization under applicable bankruptcy law):

 (a) the holders of all Senior Indebtedness shall be entitled to receive payment in full of the principal thereof (and premium, if any) and
interest due thereon before the holders of the Securities are entitled to receive any payment upon the principal (or premium, if any) or interest, if any, on Indebtedness evidenced by the Securities; and 
 (b) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the holders of the
Securities or the Trustee would be entitled except for the provisions of this Article XV shall be paid by the liquidation trustee or agent or other person making such payment or distribution, whether a trustee in bankruptcy, a receiver or
liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may
have been issued, ratably according to the aggregate amounts remaining unpaid on account of the principal of (and premium, if any) and interest on the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full
of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; and 
 (c) in the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, shall be received by the Trustee or the
holders of the Securities before all Senior Indebtedness is paid in full, such payment or distribution shall be paid over, upon written notice to a Responsible Officer of the Trustee, to the holder of such Senior Indebtedness or his, her or 

  

 -61- 








 
its representative or representatives or to the trustee or trustees under any indenture under which any instrument evidencing any of such Senior Indebtedness
may have been issued, ratably as aforesaid, for application to payment of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving effect to any concurrent payment or distribution to the
holders of such Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness, the holders of the Securities shall be subrogated to the rights of the holders of Senior Indebtedness (to the extent that distributions otherwise payable
to such holder have been applied to the payment of Senior Indebtedness) to receive payments or distributions of cash, property or securities of the Company applicable to Senior Indebtedness until the principal of (and premium, if any) and interest,
if any, on the Securities shall be paid in full and no such payments or distributions to the holders of the Securities of cash, property or securities otherwise distributable to the holders of Senior Indebtedness shall, as between the Company, its
creditors other than the holders of Senior Indebtedness, and the holders of the Securities be deemed to be a payment by the Company to or on account of the Securities. It is understood that the provisions of this Article XV are and are intended
solely for the purpose of defining the relative rights of the holders of the Securities, on the one hand, and the holders of the Senior Indebtedness, on the other hand. Nothing contained in this Article XV or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Indebtedness, and the holders of the Securities, the obligation of the Company, which is unconditional and absolute, to pay to the
holders of the Securities the principal of (and premium, if any) and interest, if any, on the Securities as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the holders of the
Securities and creditors of the Company other than the holders of Senior Indebtedness, nor shall anything herein or in the Securities prevent the Trustee or the holder of any Security from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture, subject to the rights, if any, under this Article XV of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy. Upon any
payment or distribution of assets of the Company referred to in this Article XV, the Trustee, subject to the provisions of Section 15.5, shall be entitled to rely upon a certificate of the liquidating trustee or agent or other person making any
distribution to the Trustee for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or
amounts paid or distributed thereof and all other facts pertinent thereto or to this Article XV. 
 With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform or observe only such of its covenants and objectives as are specifically set forth in this Indenture, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this
Indenture against the Trustee. The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness. The Trustee shall not be liable to any such holder if it shall pay over or distribute to or on behalf of
holders of Securities or the Company, or any other Person, moneys or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article XV. 
 Section 15.3. No Payment on Securities in Event of Default on Senior Indebtedness. Subject to Section 15.1, no payment by the Company on account of principal (or premium, if any), sinking funds or
interest, if any, on the Securities shall be made at anytime if: 
  

 -62- 








 
(i) a default on Senior Indebtedness exists that permits the holders of such Senior Indebtedness to accelerate its maturity and (ii) the default is
the subject of judicial proceedings or the Company has received notice of such default. The Company may resume payments on the Securities when full payment of amounts then due for principal (premium, if any), sinking funds and interest on Senior
Indebtedness has been made or duly provided for in money or money’s worth. 
 Section 15.4. Payments on Securities Permitted.
Subject to Section 15.1, nothing contained in this Indenture or in any of the Securities shall (a) affect the obligation of the Company to make, or prevent the Company from making, at any time except as provided in Sections 15.2 and 15.3,
payments of principal of (or premium, if any) or interest, if any, on the Securities or (b) prevent the application by the Trustee of any moneys or assets deposited with it hereunder to the payment of or on account of the principal of (or
premium, if any) or interest, if any, on the Securities, unless a Responsible Officer of the Trustee shall have received at its Corporate Trust Office written notice of any fact prohibiting the making of such payment from the Company or from the
holder of any Senior Indebtedness or from the trustee for any such holder, together with proof satisfactory to the Trustee of such holding of Senior Indebtedness or of the authority of such trustee more than two Business Days prior to the date fixed
for such payment. 
 Section 15.5. Authorization of Securityholders to Trustee to Effect Subordination. Subject to Section 15.1,
each holder of Securities by his acceptance thereof authorizes and directs the Trustee on his, her or its behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article XV and appoints the
Trustee his attorney-in-fact for any and all such purposes. 
 Section 15.6. Notices to Trustee. Subject to Section 15.1,
notwithstanding the provisions of this Article XV or any other provisions of this Indenture, neither the Trustee nor any Paying Agent (other than the Company) shall be charged with knowledge of the existence of any Senior Indebtedness or of any fact
which would prohibit the making of any payment of moneys or assets to or by the Trustee or such Paying Agent, unless and until a Responsible Officer of the Trustee or such Paying Agent shall have received (in the case of a Responsible Officer of the
Trustee, at the Corporate Trust Office of the Trustee) written notice thereof from the Company or from the holder of any Senior Indebtedness or from the trustee for any such holder, together with proof satisfactory to the Trustee of such holding of
Senior Indebtedness or of the authority of such trustee and, prior to the receipt of any such written notice, the Trustee shall be entitled in all respects conclusively to presume that no such facts exist; provided, however, that if at least two
Business Days prior to the date upon which by the terms hereof any such moneys or assets may become payable for any purpose (including, without limitation, the payment of either the principal (or premium, if any) or interest, if any, on any
Security) a Responsible Officer of the Trustee shall not have received with respect to such moneys or assets the notice provided for in this Section 15.6, then, anything herein contained to the contrary notwithstanding, the Trustee shall have
full power and authority to receive such moneys or assets and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it within two Business Days prior to such
date. The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such a notice has been given by a
holder of Senior Indebtedness or a trustee on

behalf of any such holder. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person
as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article XV, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article XV and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
 Section 15.7. Trustee as Holder of Senior Indebtedness. Subject to Section 15.1, the Trustee in its individual capacity shall be entitled to all the rights set forth in this Article XV in respect of any Senior Indebtedness at
any time held by it to the same extent as any other holder of Senior Indebtedness and nothing in this Indenture shall be construed to deprive the Trustee of any of its rights as such holder. Nothing in this Article XV shall apply to claims of, or
payments to, the Trustee under or pursuant to Sections 7.5 or 11.1. 
 Section 15.8. Modifications of Terms of Senior Indebtedness.
Subject to Section 15.1, any renewal or extension of the time of payment of any Senior Indebtedness or the exercise by the holders of Senior Indebtedness of any of their rights under any instrument creating or evidencing Senior Indebtedness,
including, without limitation, the waiver of default thereunder, may be made or done all without notice to or assent from the holders of the Securities or the Trustee. No compromise, alteration, amendment, modification, extension, renewal or other
change of, or waiver, consent or other action in respect of, any liability or obligation under or in respect of, or of any of the terms, covenants or conditions of any indenture or other instrument under which any Senior Indebtedness is outstanding
or of such Senior Indebtedness, whether or not such release is in accordance with the provisions of any applicable document, shall in any way alter or affect any of the provisions of this Article XV or of the Securities relating to the subordination
thereof. 
 Section 15.9. Reliance on Judicial Order or Certificate of Liquidating Agent. Subject to Section 15.1, upon any
payment or distribution of assets of the Company referred to in this Article XV, the Trustee and the holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit of
creditors, agent or other person making such payment or distribution, delivered to the Trustee or to the holders of Securities, for the purpose of ascertaining the persons entitled to participate in such payment or distribution to holders of Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XV. 
 Section 15.10. Satisfaction and Discharge; Defeasance and Covenant Defeasance. Subject to Section 15.1, amounts and U.S. Government
Obligations deposited in trust with the Trustee pursuant to and in accordance with Article XII and not, at the time of such deposit, prohibited to be deposited under Sections 15.2 or 15.3 shall not be subject to this Article XV.

opinion is based are erroneous. Any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters, upon a certificate, statement or opinion of, or representations by, an officer or officers of the Company

respect to such matters are erroneous. 
 (d) Any certificate, statement or opinion of an officer of the Company or of counsel to the
Company may be based, insofar as it relates to accounting matters, upon a certificate or opinion of, or representations by, an accountant or firm of accountants, unless such officer or counsel, as the case may be, knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations with respect to the accounting matters upon which his or her certificate, statement or opinion may be based are erroneous. Any certificate or opinion of any firm of

 -65- 








 (e) In any case where several matters are required to be certified by, or covered by an opinion of, any
specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with
respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 
 (f) Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 Section 16.2. Trust Indenture Act
Controls. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the duties imposed by, or another provision included in this Indenture which is required to be included in this Indenture by any of the
provisions of Sections 310 to 318, inclusive, of the Trust Indenture Act, such imposed duties or incorporated provision shall control. 
 Section 16.3. What Constitutes Action by Board of Directors. Whenever action is required by this Indenture by the Board of Directors of the Company and there is at the time constituted a committee of the Board of Directors duly
authorized to take such action, or a committee of officers or other representatives of the Company so authorized by the Board of Directors, such action by such a committee shall be deemed to be the action of the Board of Directors and shall be

 -66- 








 (a) if to Registered Holders, if given in writing by first class mail, postage prepaid, to such holders
at their addresses as the same shall appear on the Register of the Company. 
 (b) In the event of suspension of regular mail service or by
reason of any other cause it shall be impracticable to give notice by mail, then such notification as shall be given with the approval of the Trustee shall constitute sufficient notice for every purpose hereunder. 
 (c) Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance on
such waiver. In any case where notice to holders is given by mail; neither the failure to mail such notice nor any defect in any notice so mailed to any particular holder shall affect the sufficiency of such notice with respect to other holders, and
any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given. In any case where notice to holders is given by publication, any defect in any notice so published as to any particular holder shall not
affect the sufficiency of such notice with respect to other holders, and any notice that is published in the manner herein provided shall be conclusively presumed to have been duly given. 
 Section 16.6. Legal Holiday. Unless otherwise specified pursuant to Section 3.1, in any case where any Interest Payment Date, Redemption Date
or Maturity of any Security of any series shall not be a Business Day at any Place of Payment for the Securities of that series, then payment of principal and premium, if any, or interest need not be made at such Place of Payment on such date, but
may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on such Interest Payment Date, Redemption Date or Maturity and no interest shall accrue on such payment for the period from and after
such Interest Payment Date, Redemption Date or Maturity, as the case may be, to such Business Day if such payment is made or duly provided for on such Business Day.
