writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. The Trustee shall promptly
deliver to the Company copies of all such instrument or instruments delivered to the Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the
Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.1) conclusive in favor of the Trustee
and the Company, if made in the manner provided in this Section. 
  
 The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him or her the execution thereof. Where such execution is by a signer acting in a capacity other than his or her individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his or her authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner
that the Trustee deems sufficient.

 The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or
take any request, demand, authorization, direction, vote, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company may not
set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that
no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be
construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Securities of the relevant series in the manner set forth in Section 1.6. 
  
 The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any
declaration of acceleration referred to in Section 5.2, (iii) any request to institute proceedings referred to in Section 5.7(2) or (iv) any direction referred to in Section 5.12, in each case with respect to Securities of such series. If any record
date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain
Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such
record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6. 
  
 With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration
Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party
hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 
  
 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or
permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  
 (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in
writing (or by facsimile transmissions, provided that oral confirmation of receipt shall have been received) to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Department, or 
  
 (2) the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, personally delivered or sent via overnight courier to the Company addressed to it at the address of its
principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company, Attention: Chief Financial Officer. 
  
 Section 1.6 Notice to Holders; Waiver.

the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. Neither the failure to mail or deliver by hand or overnight courier any notice, nor any defect
in any notice so mailed or delivered by hand or overnight courier, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 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 upon such waiver. 
  
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder. 
  
 Section 1.7 Conflict with Trust Indenture Act. 
  
 If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture Act to be a part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust Indenture Act, which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

the Securities (other than a provision of any Security which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) or, if applicable to a particular series of Securities,

            % per annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available for
payment, and such interest shall be payable on demand]. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or

they are paid or made available for payment. Interest on any overdue principal or premium shall be payable on demand. Any such interest on overdue principal or premium which is not paid on demand shall bear interest at the rate of
            % per annum (to the extent that the payment of such interest on interest shall be legally enforceable), from the date of such demand until the amount so demanded

 [If applicable, insert — The Indenture contains provisions for defeasance at any time of [the entire indebtedness of this Security] [or] [certain restrictive covenants and Events of Default with respect to
this Security] [, in each case] upon compliance with certain conditions set forth in the Indenture.] 
  
 [If the Security is convertible into Common Stock of the Company, insert — Subject to the provisions of the Indenture, the Holder of this
Security is entitled, at its option, at any time on or before [insert date] (except that, in case this Security or any portion hereof shall be called for redemption, such right shall terminate with respect to this Security or portion hereof,
as the case may be, so called for redemption at the close of business on the first Business Day next preceding the date fixed for redemption as provided in the Indenture unless the Company defaults in making the payment due upon redemption), to
convert the principal amount of this Security (or any portion hereof which is $1,000 or an integral multiple thereof), into fully paid and non-assessable shares (calculated as to each 

  

 14 








 
conversion to the nearest 1/100th of a share) of the Common Stock of the Company, as said shares shall be constituted at the date of conversion, at the
conversion price of $             principal amount of Securities for each share of Common Stock, or at the adjusted conversion price in effect at the date of conversion determined as
provided in the Indenture, upon surrender of this Security, together with the conversion notice hereon duly executed, to the Company at the designated office or agency of the Company
in             , accompanied (if so required by the Company) by instruments of transfer, in form satisfactory to the Company and to the Trustee, duly executed by the Holder or by its duly
authorized attorney in writing. 
  
 Such surrender shall, if made
during any period beginning at the close of business on a Regular Record Date and ending at the opening of business on the Interest Payment Date next following such Regular Record Date (unless this Security or the portion being converted shall have
been called for redemption on a Redemption Date during the period beginning at the close of business on a Regular Record Date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, or if such
Interest Payment Date is not a Business Day, the second such Business Day), also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this
Security then being converted. Subject to the aforesaid requirement for payment and, in the case of a conversion after the Regular Record Date next preceding any Interest Payment Date and on or before such Interest Payment Date, to the right of the
Holder of this Security (or any Predecessor Security) of record at such Regular Record Date to receive an installment of interest (with certain exceptions provided in the Indenture), no adjustment is to be made on conversion for interest accrued
hereon or for dividends on shares of Common Stock issued on conversion. The Company is not required to issue fractional shares upon any such conversion, but shall make adjustment therefor in cash on the basis of the current market value of such
fractional interest as provided in the Indenture. The conversion price is subject to adjustment as provided in the Indenture. In addition, the Indenture provides that in case of certain consolidations or mergers to which the Company is a party or
the sale of substantially all of the assets of the Company, the Indenture shall be amended, without the consent of any Holders of Securities, so that this Security, if then outstanding, will be convertible thereafter, during the period this Security
shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon the consolidation, merger or sale by a holder of the number of shares of Common Stock into which this Security might have
been converted immediately prior to such consolidation, merger or sale (assuming such holder of Common Stock failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of non-electing
shares). In the event of conversion of this Security in part only, a new Security or Securities for the unconverted portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.] 
  
 [If the Security is convertible into other securities of the Company,
specify the conversion features.] 
  
 The indebtedness
evidenced by this Security is, to the extent and in the manner provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Debt of the Company, and this Security is issued subject to such
provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary
or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. 
  
 [If the Security is not an Original Issue Discount Security, insert — If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.] 
  
 [If the Security is an Original Issue Discount Security, insert — If an Event of Default with respect to
Securities of this series shall occur and be continuing, an amount of principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. Such amount shall be equal to —
insert formula for determining the amount. Upon payment (i) of the amount of principal so declared due and payable and (ii) of interest on any overdue principal, premium and interest (in each case to the extent that the payment of such
interest shall be legally enforceable), all of the Company’s obligations in respect of the payment of the principal of and premium and interest, if any, on the Securities of this series shall terminate.] 
  
 The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be 

  

 15 








 
affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of more than 50% in principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security. 
  
 As provided in and subject
to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder
shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than a majority in principal amount of the Securities of this series at the time
Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority
in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity.
The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 
  
 No reference herein to the Indenture and no provision of this Security or of
the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein
prescribed. 
  
 As provided in the Indenture and subject to
certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and
any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or its attorney duly
authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
  
 The Securities of this series are issuable only in registered form without
coupons in denominations of $ and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities
of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
  
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. 
  
 Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
  
 All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

without coupons and only in such denominations as shall be specified as contemplated by Section 3.1. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof. 
  
 Section 3.3
Execution, Authentication, Delivery and Dating. 
  
 The
Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief Executive Officer, its principal financial officer, its President or one of its Vice Presidents, attested by its Treasurer,
its Secretary or one of its Assistant Treasurers or Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. 
  

 20 








 Securities bearing the manual or facsimile signatures of individuals who were at any time the proper
officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such
Securities. 
  
 At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the
Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.1 and
3.1, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying
upon, a copy of such Board Resolution, the Officers’ Certificate setting forth the terms of the series and an Opinion of Counsel, with such Opinion of Counsel stating, 
  
 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by
Section 2.1, that such form has been established in conformity with the provisions of this Indenture; 
  
 (2) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.1, that such terms
have been established in conformity with the provisions of this Indenture; and 
  
 (3) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
  
 If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant
to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee. 
  
 Notwithstanding the provisions of Section 3.1 and of the preceding paragraph,
if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or the Company Order and Opinion of Counsel otherwise required
pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

  
 Each Security shall be dated the date of its authentication.

  
 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 the form provided for herein executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never
issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.9, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture. 
  
 Neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Security, check, advice of payment or redemption notice, and any such document may contain a
statement to the effect that CUSIP numbers have been assigned by an independent service for convenience of reference and that neither the Company nor the Trustee shall be liable for any inaccuracy in such numbers. 
  

 21 








 Section 3.4 Temporary Securities. 
  
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee
shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 
  
 If temporary Securities of any series are issued, the Company will cause
definitive Securities of that 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 the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that 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 one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. 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 and tenor. 
  
 Section 3.5 Registration; Registration of Transfer and Exchange. 
  
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register 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 “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
  
 Upon surrender for registration of transfer of any Security of a series at
the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of like tenor and aggregate principal amount. 
  
 At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency. 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. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange. 
  
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed, by the Holder thereof or its attorney duly authorized in writing. 
  
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4, 9.6 or 11.7 not involving any transfer. 
  
  
 If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 11.3 and ending at the close of
business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
  

 22 








 The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities: 

 
 (1) Each Global Security authenticated under this
Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture. 
  
 (2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any
Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a
clearing agency registered under the Exchange Act, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) there shall exist such circumstances, if any, in addition to or in lieu of the
foregoing as have been specified for this purpose as contemplated by Section 3.1. 
  
 (3) Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all
Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct. 
  
 (4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in
lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.7 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered
in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 
  
 Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities. 
  
 If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
  
 If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously
outstanding. 
  
 In case any such mutilated, destroyed, lost or
stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
  
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
  
 Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other
Securities of that series duly issued hereunder. 
  
 The
provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  

 23 








 Section 3.7 Payment of Interest; Interest Rights Preserved. 
  
 Except as otherwise provided as contemplated by Section 3.1 with respect to
any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such interest. 
  
 Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be
payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 
  
 (1) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, 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 Security of such series 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 days and not less than 10 days prior to the date of the proposed payment and not less than 10 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 given to each Holder of Securities of such series in the manner set forth in
Section 1.6, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose
names the Securities of such series (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 (2). 
  
 (2) The Company may make payment of any Defaulted Interest
on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such 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. 
  
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or
in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
  
 Subject to the provisions of Section 14.2, in the case of any Security (or any part thereof) which is converted after any Regular Record Date and on or
prior to the next succeeding Interest Payment Date (other than any Security the principal of (or premium, if any, on) which shall become due and payable, whether at Stated Maturity or by declaration of acceleration or otherwise prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion and such interest (whether or not punctually paid or duly provided for) shall be
paid to the Person in whose name that Security (or any one or more Predecessor Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence or in Section
14.2, in the case of any Security (or any part thereof) which is converted, interest whose Stated Maturity is after the date of conversion of such Security (or such part thereof) shall not be payable. 
  

 24 








 Section 3.8 Persons Deemed Owners. 
  
 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.7) any interest on such Security and for all
other purposes whatsoever, whether or not such 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. 
  
 Section 3.9 Cancellation. 
  
 All Securities surrendered for payment, redemption, registration of transfer
or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any
Securities previously authenticated hereunder which the Company has not issued and sold, 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. All canceled Securities held by the Trustee shall be disposed of in accordance with its customary procedures. 
  
 Section 3.10 Computation of Interest. 
  
 Except as otherwise specified as contemplated by 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. 
  
 ARTICLE 4 
  
 SATISFACTION AND DISCHARGE 
  
 Section 4.1 Satisfaction and Discharge of Indenture. 
  
 This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when 
  
 (1) either 
  
 (A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which
have been replaced or paid as provided in Section 3.6 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Trustee or the Company and thereafter repaid to the Company or
discharged from such trust, as provided in Section 10.3) have been delivered to the Trustee for cancellation; or 
  
 (B) all such Securities not theretofore delivered to the Trustee for cancellation 
  
 (i) have become due and payable, or 
  
 (ii) will become due and payable at their Stated Maturity
within one year, or 
  
 (iii) are to be called
for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
  
 and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust
funds in trust for the purpose money in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such
deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 
  

 25 








 (2) the Company has paid or caused to be paid all other sums payable hereunder by the
Company; and 
  
 (3) the Company has delivered to
the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. 
  
 Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of the Trustee to any Authenticating Agent under Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this
Section, the obligations of the Trustee under Section 4.2 and the last paragraph of Section 10.3 shall survive. 
  
 Section 4.2 Application of Trust Money. 
  
 Subject to the provisions of the last paragraph of Section 10.3, all money deposited with the Trustee pursuant to Section 4.1 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee. 
  
 ARTICLE 5 
  
 REMEDIES 
  
 Section 5.1 Events of Default. 
  
 “Event of
Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article 15 or be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), unless in the Board Resolution, supplemental indenture or
Officers’ Certificate establishing such series, it is provided that such series shall not have the benefit of said Event of Default: 
  
 (1) default in the payment of any interest upon any Security of that series when it becomes due and payable, and continuance of such
default for a period of 30 days; or 
  
 (2)
default in the payment of the principal of or any premium on any Security of that series at its Maturity; or 
  
 (3) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series; or 
  
 (4) default in the performance, or breach, of any covenant
or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee
by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default”
hereunder; or 
  
 (5) the entry by a court having
jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or
order adjudging the Company a bankrupt or 

  

 26 








 
insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any
applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its
affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or 
  
 (6) the commencement by the Company of a voluntary case or proceeding under any applicable Federal or State
bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an involuntary
case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or
consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee,
sequestrator or other similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as
they become due, or the taking of corporate action by the Company in furtherance of any such action; or 
  
 (7) any other Event of Default provided with respect to Securities of that series in the Board Resolution, supplemental indenture or
Officers’ Certificate establishing that series. 
  
 Section 5.2
Acceleration of Maturity; Rescission and Annulment. 
  
 Unless the Board Resolution, supplemental indenture or Officers’ Certificate establishing such series provides otherwise, if an Event of Default (other than an Event of Default specified in Section 5.1(5) or 5.1(6)) with respect to
Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of
all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) and premium, if any, together with
accrued and unpaid interest, if any, thereon, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal amount (or specified amount) and
premium, if any, together with accrued and unpaid interest, if any, thereon, shall become immediately due and payable. If an Event of Default specified in Section 5.1(5) or 5.1(6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) and
premium, if any, together with accrued and unpaid interest, if any, thereon, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. Any payments by the Company
on the Securities following any such acceleration will be subject to the subordination provisions of Article 15 to the extent provided therein. 
  
 At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of
the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and
annul such declaration and its consequences if 
  
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay 
  
 (A) all overdue interest on all Securities of that series, 
  
 (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise
than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 
  
 (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such
Securities, and 
  

 27 








 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel; and 
  
 (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that
series that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. No such rescission shall affect any subsequent default or impair any right consequent thereon. 
  
 Section 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee.

  
 The Company covenants that if 
  
 (1) default is made in the payment of any interest on any
Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
  
 (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, the Company will,
upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
  
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
  
 Section 5.4 Trustee May File Proofs of Claim. 
  
 In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be
entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the
Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it
for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.7. No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar
committee. 
  
 Section 5.5 Trustee May Enforce Claims Without Possession of
Securities. 
  
 All rights of action and claims under this
Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
  

 28 








 Section 5.6 Application of Money Collected. 
  
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates
fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if
fully paid: 
  
 FIRST: To the payment of all amounts due the
Trustee under Section 6.7; 
  
 SECOND: Subject to Article 15, to
the payment of the amounts then due and unpaid for principal of and any premium, if any, and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any
kind, according to the amounts due and payable on such Securities for principal and any premium, if any, and interest, respectively; and 
  
 THIRD: The balance, if any, to the Company or any other Person or Persons entitled thereto. 
  
 Section 5.7 Limitation on Suits. 
  
 No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
  
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that
series; 
  
 (2) the Holders of more than 50% in
principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
  
 (3) such Holder or Holders have offered to the Trustee
reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 
  
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
  
 (5) no direction inconsistent with such
written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of
such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 
  
 Section 5.8 Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert. 
  
 Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.7) interest on such Security on the respective Stated Maturities expressed in such Security (or, in
the case of redemption, on the Redemption Date), to convert such Securities in accordance with Article 14 to the extent that such right to convert is applicable to such Security, and to institute suit for the enforcement of any such payment, and
such rights shall not be impaired without the consent of such Holder. 
  

 29 








 Section 5.9 Restoration of Rights and Remedies. 
  
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
  
 Section 5.10 Rights and Remedies Cumulative. 
  
 Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder,
or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  
 Section 5.11 Delay or Omission Not Waiver. 
  
 No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee (subject to the limitations contained in this Indenture) or by the Holders, as the case may be. 
  
 Section 5.12 Control by Holders. 
  
 The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that 
  
 (1) such direction shall not be in conflict with any rule of law or with this Indenture and the Trustee
shall not have determined that the action so directed would be unjustly prejudicial to Holders of Securities of that series, or any other series, not taking part in such direction; and 
  
 (2) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such
direction or this Indenture. 
  
 Section 5.13 Waiver of Past Defaults.

  
 The Holders of not less than a majority in principal
amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except 
  
 (1) a default in the payment of the principal of or any
premium or interest on any Security of such series as and when the same shall become due and payable by the terms thereof, otherwise than by acceleration (unless such default has been cured and a sum sufficient to pay all matured installments of
interest, principal and premium, if any, has been deposited with the Trustee), or 
  
 (2) to the extent such right is applicable to such Security, a failure by the Company on request to convert any Security into Common
Stock; or 
  
 (3) in respect of a covenant or
provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
  

 30 








 Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
  
 Section 5.14 Undertaking for Costs. 
  
 In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted
by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act;
provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or in any suit for the enforcement of the right
to convert any Security in accordance with Article 14. 
  
 Section 5.15 Waiver
of Usury, Stay or Extension Laws. 
  
 The Company covenants
(to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
  
 ARTICLE 6 
  
 THE TRUSTEE 
  
 Section 6.1 Certain Duties and Responsibilities. 
  
 The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise 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 it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 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. 
  
 Section 6.2 Notice of Defaults. 
  
 If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust Indenture Act; provided,
however, that except in the case of a default in the payment of principal of (or premium, if any) or interest on any Securities of such series or in the payment of any sinking fund installment or any conversion right applicable to Securities
of such series, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of
the holders of Securities of such series; provided, further, however, that in the case of any default of the character specified in Section 5.1(4) with respect to Securities of such series, no such notice to Holders shall be
given until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event that is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities
of such series. 
  

 31 








 Section 6.3 Certain Rights of Trustee. 
  
 Subject to the provisions of Section 6.1: 
  
 (1) in the absence of bad faith on the part of the Trustee, the Trustee may rely and shall be protected in
acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to
be genuine and to have been signed or presented by the proper party or parties;

any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution; 
  
 (3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) is entitled to and may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 
  
 (4) the Trustee may consult with counsel and the written
advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
  
 (5) the Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses
and liabilities which might be incurred by it in compliance with such request or direction; 
  
 (6) 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, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; and

  
 (7) the Trustee may execute any of the trusts
or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it
hereunder. 
  
 Section 6.4 Not Responsible for Recitals or Issuance of
Securities. 
  
 The recitals contained herein and in the
Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity, sufficiency or priority of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds
thereof. 
  
 Section 6.5 May Hold Securities and Act as Trustee under Other
Indentures. 
  
 The Trustee, any Authenticating Agent, any
Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.8 and 6.13, may otherwise deal with the Company with the same
rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
  
 Subject to the limitations imposed by the Trust Indenture Act, nothing in this Indenture shall prohibit the Trustee from becoming and acting as trustee
under other indentures under which other securities, or certificates of interest of participation in other securities, of the Company are outstanding in the same manner as if it were not Trustee hereunder. 
  

 32 








 Section 6.6 Money Held in Trust. 
  
 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. 
  
 Section 6.7 Compensation and Reimbursement. 
  
 The Company agrees: 
  
 (1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall
not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
  
 (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as
may be attributable to its negligence or bad faith and 
  
 (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or
trusts hereunder, including 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. 
  
 Section 6.8 Conflicting Interests. 
  
 If the Trustee has or shall acquire a conflicting interest within the
meaning 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. To the extent permitted by the
Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series. 
  
 Section 6.9 Corporate Trustee Required; Eligibility. 
  
 There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be
Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has (or if the Trustee is a member of a bank holding company system, its bank
holding company has) a combined capital and surplus of at least $50,000,000. If any such Person or bank holding company publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining
authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person or bank holding company 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 the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article. 
  
 Section 6.10
Resignation and Removal; Appointment of Successor. 
  
 No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section
6.11. The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been
delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

  

 33 








 The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 
  
 If at any time: 
  
 (1) the Trustee shall fail to comply with Section 6.8 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 6.9 and shall fail to resign after written request therefor by the Company or by any such Holder, 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, (A) the
Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder 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. 
  
 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee
for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees 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 particular series) and shall comply with the applicable
requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the
applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities
of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, the retiring Trustee may petition, or any Holder who has been a bona fide Holder of a Security of such series
for at least six months may petition, on behalf of himself and all others similarly situated, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
  
 The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.6. Each notice shall
include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
  
 Section 6.11 Acceptance of Appointment by Successor. 
  
 In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee
hereunder. 
  
 In case of the appointment hereunder of a successor
Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or 

  

 34 








 
more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such
Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring
Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee
relates. 
  
 Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 

 
 No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under this Article. 
  
 Section 6.12 Merger, Conversion, Consolidation or Succession to Business. 
  
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee (including the administration of the trust created by this Indenture), shall be
the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated
with the same effect as if such successor Trustee had itself authenticated such Securities. In the event that any Securities shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such
Securities in either its own name or that of a predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee. 
  
 Section 6.13 Preferential Collection of Claims Against Company. 
  
 If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee
shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 
  
 Section 6.14 Appointment of Authenticating Agent. 
  
 The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.6, and 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. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s
certificate of authentication, such reference 

  

 35 








 
shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on
behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business 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 (or if the Authenticating Agent is a member of a bank holding company system, its bank holding company has) 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 Authenticating Agent 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 Section, the combined capital and surplus of such Authenticating Agent 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 Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 
  
 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 Section, 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, the Trustee may appoint a successor Authenticating Agent which
shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.6 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. 
  
 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section
6.7. 
  
 If an appointment with respect to one or more series is
made pursuant to this Section 6.12, the Securities of such series may have endorsed thereon, in lieu of the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
  
 This is one of the Securities of the series designated therein referred to in
the within-mentioned Indenture.

 Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new

Outstanding Securities of such series. 
  
 Section 9.7 Subordination

 ARTICLE 10 
  
 COVENANTS 
  
 Section 10.1 Payment of Principal, Premium and
Interest. 
  
 The Company covenants and agrees for the
benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture. 
  
 Section 10.2 Maintenance of Office or Agency. 
  
 The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of that series may be
surrendered for conversion and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. 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 its agent to receive all such presentations, surrenders, notices and demands. Unless otherwise provided in a supplemental indenture or
pursuant to Section 3.1 hereof, the Place of Payment for any series of Securities shall be the Corporate Trust Office of the Trustee. 
  
 The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

  
 Section 10.3 Money for Securities Payments to be Held in Trust.

  
 If the Company shall at any time act as its own Paying
Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

  
 Whenever the Company shall have one or more Paying Agents for
any series of Securities, it will, on or prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the
Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
  

 41 








 The Company will cause each Paying Agent for any series of Securities other than the Trustee 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, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a
Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. 
  
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, 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;
and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 
  
 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 or any premium or
interest on any Security of any series and remaining unclaimed for a period ending on the earlier of the date that is ten Business Days prior to the date such money would escheat to the State or two years after such principal, premium or interest
has become due and payable shall be paid to the Company on Company Request, 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 thereof, 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 published once, in a newspaper published in the English language, customarily published on each Business Day and of general
circulation in each Place of Payment, 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 publication, any unclaimed balance of such money then remaining will
be repaid to the Company. 
  
 Section 10.4 Statement by Officers as to Default.

  
 The Company will deliver to the Trustee, within 120 days
after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge. The fiscal year of the Company currently ends on December 31; and the Company will give the Trustee prompt written notice of any change of its fiscal year. 
  
 Section 10.5 Existence. 
  
 Subject to Article 8, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence.

  
 Section 10.6 Maintenance of Properties. 
  
 The Company will cause all properties used or useful in the conduct of its
business to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as, and to
the extent, in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the
Holders. 
  

 42 








 Section 10.7 Payment of Taxes and Other Claims. 
  
 The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes,
assessments and governmental charges levied or imposed upon the Company or upon the income, profits or property of the Company, and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim (i) whose amount, applicability or validity is being
contested in good faith by appropriate proceedings or (ii) if the failure to pay or discharge would not have a material adverse effect on the assets, business, operations, properties or condition (financial or otherwise) of the Company and its
subsidiaries, taken as a whole. 
  
 Section 10.8 Waiver of Certain Covenants.

  
 Except as otherwise specified as contemplated by Section
3.1 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.1(19), 9.1(2),
9.1(7), 10.6 or 10.7 for the benefit of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive
such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver
shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
  
 ARTICLE 11 
  
 REDEMPTION OF SECURITIES 
  
 Section 11.1 Applicability of Article. 
  
 Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 3.1 for such Securities) in accordance with this Article. 
  
 Section 11.2 Election to Redeem; Notice to Trustee. 
  
 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.1 for such Securities. In case of any redemption at the
election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption
of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with
such restriction. 
  
 Section 11.3 Selection by Trustee of Securities to Be
Redeemed. 
  
 If less than all the Securities of any series
are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by lot, or in the Trustee’s discretion, on a pro-rata basis, provided that the unredeemed portion of the principal
amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless
such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence. 
  

 43 








 If any Security selected for partial redemption is converted in part before termination of the conversion
right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities that have been converted during a selection of Securities
to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 
  
 The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected
for partial redemption as aforesaid, the principal amount thereof to be redeemed. 
  
 The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. 
  
 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 Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. 

 
 Section 11.4 Notice of Redemption. 
  
 Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not fewer than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address appearing in the Security Register.

  
 All notices of redemption shall state: 
  
 (1) the Redemption Date, 
  
 (2) the Redemption Price (including accrued interest, if
any), 
  
 (3) if less than all the Outstanding
Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less
than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed, 
  
 (4) in case any Security is to be redeemed in part only, that on and after the Redemption Date, upon
surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed, 
  
 (5) that on the Redemption Date the Redemption Price will
become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 
  
 (6) the place or places where each such Security is to be surrendered for payment of the Redemption Price, 
  
 (7) if applicable, the conversion price, the date on which
the right to convert the principal of the Securities or the portions thereof to be redeemed will terminate, and the place or places where such Securities may be surrendered for conversion, 
  
 (8) that the redemption is for a sinking fund, if such is
the case, and 
  
 (9) the CUSIP number or numbers
and/or common codes of the Security being redeemed. 
  

 44 








 Notice of redemption of Securities to be redeemed at the election of the Company 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 and shall be irrevocable. 
  
 Section 11.5 Deposit of Redemption Price. 
  
 On or prior to any Redemption Date, 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 10.3) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to
be redeemed on that date. 
  
 If any Security called for
redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to the right of any Holder of such Security to receive interest as provided in
the last paragraph of Section 3.7) be paid to the Company on Company Request, or if then held by the Company, shall be discharged from such trust. 
  
 Section 11.6 Securities Payable on Redemption Date. 
  
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) 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, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated
by Section 3.1, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section 3.7. 
  
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor
in the Security. 
  
 Section 11.7 Securities Redeemed in Part. 

 
 Any Security which is to be redeemed only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof 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 and of like tenor, 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. 
  
 ARTICLE 12 
  
 SINKING FUNDS 
  
 Section 12.1 Applicability of Article. 
  
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities. 
  
 The minimum
amount of any sinking fund payment provided for by the terms of any Securities 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 such Securities is
herein referred to as an “optional sinking fund payment.” If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall
be applied to the redemption of Securities as provided for by the terms of such Securities. 
  

 45 








 Section 12.2 Satisfaction of Sinking Fund Payments with Securities. 
  
 The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as
and to the extent provided for by the terms of such Securities; provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at
the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
  
 Section 12.3 Redemption of Securities for Sinking Fund. 
  
 Not fewer than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 12.2 and will also deliver to the Trustee any Securities to be so delivered. Not fewer than 30 days
prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given in the name of
and at the expense of the Company in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.6 and 11.7. 
  
 ARTICLE 13 
  
 DEFEASANCE AND COVENANT DEFEASANCE 
  
 Section 13.1 Company’s Option to Effect Defeasance or Covenant Defeasance.

  
 The Company may elect, at its option at any time, to have

provided in this Section on and after the date the conditions set forth in Section 13.4 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: 
  
 (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 13.4 and as more fully set forth

 (4) this Article. 
  
 Subject to compliance with this Article, the Company may exercise its option (if any) to have this Section applied to any Securities notwithstanding the
prior exercise of its option (if any) to have Section 13.3 applied to such Securities. 
  
 Section 13.3 Covenant Defeasance. 
  
 Upon the
Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, 
  
 (1) the Company shall be released from its obligations under Sections 10.6 and 10.7 and any covenants provided pursuant to Sections
3.1(19), 9.1(2) or 9.1(7) for the benefit of the Holders of such Securities,

Event of Default specified pursuant to Section 3.1, shall be deemed not to be or result in an Event of Default, and

 in each case with respect to such Securities or series of Securities as provided in this Section on and after the date the conditions set
forth in Section 13.4 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 5.1(4) and the occurrence of any Event of Default specified pursuant to Section 3.1) or Article 15, whether
directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby. 
  
 Section 13.4

to, the benefits of the Holders of such Securities, 
  
 (A) in the case of Securities of a series denominated in currency of the United States of America, 
  
 (i) cash in currency of the United States of America in an amount, or

through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, an amount in cash, or 
  
 (iii) a combination thereof, 
  
 in each case sufficient, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and
interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. 
  
 (2) In the event of an election to have Section 13.2 apply to any Securities or any series of Securities, as the case may be, the Company

 (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or 
  
 (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, 
  
 in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm
that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 
  
 (3) In the event of an election to have Section 13.3 apply to any Securities or any series of Securities, as the case may be, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with

both would become, an Event of Default with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 5.1(5) and (6), at any time on
or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day).

Indenture Act (assuming all Securities are in default within the meaning of such Act). 
  
 (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or
any other agreement or instrument to which the Company is a party or by which it is bound. 
  

 48 








 (8) Such Defeasance or Covenant Defeasance shall not result in the trust arising from
such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration thereunder. 
  
 (9) At the time of such deposit, 
  
 (A) no default in the payment of any principal of or premium
or interest on any Senior Debt shall have occurred and be continuing,

(unless payment of such Senior Debt has been made or duly provided for), and 
  
 (C) no other event of default with respect to any Senior Debt shall have occurred and be continuing permitting (after notice or lapse of time or both) the holders of such Senior Debt (or a trustee on behalf of such
holders) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable. 
  
 (10) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
  
 Section 13.5 Deposited Money, U.S. Government Obligations and Foreign Government Obligations to be Held in Trust; Miscellaneous Provisions. 
  
 Subject to the provisions of the last paragraph of Section 10.3, all money, U.S. Government Obligations and Foreign
Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 13.6, the Trustee and any such other trustee are referred to collectively as the
“Trustee”) pursuant to Section 13.4 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so
held in trust need not be segregated from other funds except to the extent required by law. Money, U.S. Government Obligations and Foreign Government Obligations so held in trust shall not be subject to the provisions of Article 15. 
  
 The Company shall pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the U.S. Government Obligations or Foreign Government Obligations deposited pursuant to Section 13.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of Outstanding Securities. 
  
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money, U.S. Government Obligations or Foreign Government Obligations held by it as provided
in Section 13.4 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which
would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities. 
  
 Section 13.6 Reinstatement. 
  
 If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to
Section 13.2 or 13.3 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to
Section 13.5 with respect to such Securities in 

  

 49 








 
accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust. 
  
 ARTICLE 14 
  
 CONVERSION OF SECURITIES 
  
 Section 14.1 Applicability of Article. 
  
 The provisions of this Article shall be applicable to the Securities of any
series which are convertible into shares of Common Stock of the Company, and the issuance of such shares of Common Stock upon the conversion of such Securities, except as otherwise specified as contemplated by Section 3.1 for the Securities of such
series. 
  
 Section 14.2 Exercise of Conversion Privilege. 
  
 In order to exercise a conversion privilege, the Holder of a Security of a
series with such a privilege shall surrender such Security to the Company at the office or agency maintained for that purpose pursuant to Section 10.2, accompanied by a duly executed conversion notice to the Company substantially in the form set
forth in Section 2.6 stating that the Holder elects to convert such Security or a specified portion thereof. Such notice shall also state, if different from the name and address of such Holder, the name or names (with address) in which the
certificate or certificates for shares of Common Stock, which shall be issuable on such conversion, shall be issued. Securities surrendered for conversion shall (if so required by the Company or the Trustee) be duly endorsed by or accompanied by
instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the Holder or its attorney duly authorized in writing; and Securities so surrendered for conversion (in whole or in part) during the period from the close
of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (excluding Securities or portions thereof called for redemption during the period beginning at the close of business on a Regular Record
Date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, or if such Interest Payment Date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of such Security then being converted, and such interest shall be payable to such Holder notwithstanding the conversion of
such Security, subject to the provisions of Section 3.7 relating to the payment of Defaulted Interest by the Company. As promptly as practicable after the receipt of such notice and of any payment required pursuant to a Board Resolution and, subject
to Section 3.3, set forth, or determined in the manner provided, in an Officers’ Certificate, or established in one or more indentures supplemental hereto setting forth the terms of such series of Security, and the surrender of such Security in
accordance with such reasonable regulations as the Company may prescribe, the Company shall issue and shall deliver, at the office or agency at which such Security is surrendered, to such Holder or on its written order, a certificate or certificates
for the number of full shares of Common Stock issuable upon the conversion of such Security (or specified portion thereof), in accordance with the provisions of such Board Resolution, Officers’ Certificate or supplemental indenture, and cash as
provided therein in respect of any fractional share of such Common Stock otherwise issuable upon such conversion. Such conversion shall be deemed to have been effected immediately prior to the close of business on the date on which such notice and
such payment, if required, shall have been received in proper order for conversion by the Company and such Security shall have been surrendered as aforesaid (unless such Holder shall have so surrendered such Security and shall have instructed the
Company to effect the conversion on a particular date following such surrender and such Holder shall be entitled to convert such Security on such date, in which case such conversion shall be deemed to be effected immediately prior to the close of
business on such date) and at such time the rights of the Holder of such Security as such Security Holder shall cease and the person or persons in whose name or names any certificate or certificates for shares of Common Stock of the Company shall be
issuable upon such conversion shall be deemed to have become the Holder or Holders of record of the shares represented thereby. Except as set forth above and subject to the final paragraph of Section 3.7, no payment or adjustment shall be made upon
any conversion on account of any interest accrued on the Securities (or any part thereof) surrendered for conversion or on account of any dividends on the Common Stock of the Company issued upon such conversion. 
  

 50 








 In the case of any Security which is converted in part only, upon such conversion the Company shall
execute and the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of the same series, of authorized denominations, in aggregate principal amount equal to the
unconverted portion of such Security. 
  
 Section 14.3 No Fractional Shares.

  
 No fractional share of Common Stock of the Company shall
be issued upon conversions of Securities of any series. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of
the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If, except for the provisions of this Section 14.3, any Holder of a Security or Securities would be entitled to a
fractional share of Common Stock of the Company upon the conversion of such Security or Securities, or specified portions thereof, the Company shall pay to such Holder an amount in cash equal to the current market value of such fractional share
computed, (i) if such Common Stock is listed or admitted to unlisted trading privileges on a national securities exchange or market, on the basis of the last reported sale price regular way on such exchange or market on the last trading day prior to
the date of conversion upon which such a sale shall have been effected, or (ii) if such Common Stock is not at the time so listed or admitted to unlisted trading privileges on a national securities exchange or market, on the basis of the average of
the bid and asked prices of such Common Stock in the over-the-counter market, on the last trading day prior to the date of conversion, as reported by the National Quotation Bureau, Incorporated or similar organization if the National Quotation
Bureau, Incorporated is no longer reporting such information, or if not so available, the fair market price as determined by the Board of Directors. For purposes of this Section, “trading day” shall mean each Monday, Tuesday, Wednesday,
Thursday and Friday other than any day on which the Common Stock is not traded on the Nasdaq National Market, or if the Common Stock is not traded on the Nasdaq National Market, on the principal exchange or market on which the Common Stock is traded
or quoted. 
  
 Section 14.4 Adjustment of Conversion Price. 
  
 The conversion price of Securities of any series that is convertible into
Common Stock of the Company shall be adjusted for any stock dividends, stock splits, reclassifications, combinations or similar transactions in accordance with the terms of the supplemental indenture or Board Resolutions setting forth the terms of
the Securities of such series. 
  
 Whenever the conversion price
is adjusted, the Company shall compute the adjusted conversion price in accordance with terms of the applicable Board Resolution or supplemental indenture and shall prepare an Officers’ Certificate setting forth the adjusted conversion price
and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.2 and, if different,
with the Trustee. The Company shall forthwith cause a notice setting forth the adjusted conversion price to be mailed, first class postage prepaid, to each Holder of Securities of such series at its address appearing on the Security Register and to
any conversion agent other than the Trustee. 
  
 Section 14.5 Notice of Certain
Corporate Actions. 
  
 In case: 
  
 (1) the Company shall declare a dividend (or any other
distribution) on its Common Stock payable otherwise than in cash out of its retained earnings (other than a dividend for which approval of any shareholders of the Company is required) that would require an adjustment pursuant to Section 14.4; or

  
 (2) the Company shall authorize the granting
to all or substantially all of the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights (other than any such grant for which approval of any
shareholders of the Company is required); or 
  
 (3) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares of Common Stock, or of any consolidation, merger or share exchange to which the Company is a party and for
which approval of any shareholders of the Company is required), or of the sale of all or substantially all of the assets of the Company; or 
  

 51 








 (4) of the voluntary or involuntary dissolution, liquidation or winding up of the
Company; 
  
 then the Company shall cause to be filed with the
Trustee, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Security Register, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the applicable record date
hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock
of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined, or (ii) the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is
expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification,
consolidation, merger, share exchange, sale, dissolution, liquidation or winding up. If at any time the Trustee shall not be the conversion agent, a copy of such notice shall also forthwith be filed by the Company with the Trustee. 
  
 Section 14.6 Reservation of Shares of Common Stock. 
  
 The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock of the Company then issuable upon the conversion of all outstanding Securities
of any series that has conversion rights. 
  
 Section 14.7 Payment of Certain
Taxes upon Conversion. 
  
 Except as provided in the next
sentence, the Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares of its Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issue and delivery of shares of its Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and
until the person requesting such issue has paid to the Company the amount of any such tax, or has established, to the satisfaction of the Company, that such tax has been paid. 
  
 Section 14.8 Nonassessability. 
  
 The Company covenants that all shares of its Common Stock that may be issued upon conversion of Securities will upon issue in accordance with the terms
hereof be duly and validly issued and fully paid and nonassessable. 
  
 Section
14.9 Provision in Case of Consolidation, Merger or Sale of Assets. 
  
 In case of any consolidation or merger of the Company with or into any other Person, any merger of another Person with or into the Company (other than a merger which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or any conveyance, sale, transfer or lease of all or substantially all of the assets of the Company, the Person formed by such consolidation or resulting from such merger or which
acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security of a series then Outstanding that is convertible into Common Stock of the Company shall have the
right thereafter (which right shall be the exclusive conversion right thereafter available to said Holder), during the period such Security shall be convertible, to convert such Security only into the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by a holder of the number of shares of Common Stock of the Company into which such Security might have been converted immediately prior to such consolidation,
merger, conveyance, sale, transfer or lease, assuming such holder of Common Stock of the Company (i) is not a Person with which the Company consolidated or merged with or into or which merged into or with the Company or to which such conveyance,
sale, transfer or lease was made, as the case may be (a “Constituent Person”), or an Affiliate of a Constituent Person and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash 

  

 52 








 
and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease (provided that if the kind or amount of securities, cash
and other property receivable upon such consolidation, merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the Company held immediately prior to such consolidation, merger, conveyance, sale, transfer or
lease by others than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised (“Non-electing Share”), then for the purpose of this Section 14.9 the kind and amount of
securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by the holders of each Non-electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the
Non-electing Shares). Such supplemental indenture shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in
this Article or in accordance with the terms of the supplemental indenture or Board Resolutions setting forth the terms of such adjustments. The above provisions of this Section 14.9 shall similarly apply to successive consolidations, mergers,
conveyances, sales, transfers or leases. Notice of the execution of such a supplemental indenture shall be given by the Company to the Holder of each Security of a series that is convertible into Common Stock of the Company as provided in Section
1.6 promptly upon such execution. 
  
 Neither the Trustee nor any
conversion agent, if any, shall be under any responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property or cash
receivable by Holders of Securities of a series convertible into Common Stock of the Company upon the conversion of their Securities after any such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may accept
as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Opinion of Counsel with respect thereto, which the Company shall cause to be furnished to the Trustee upon request. 
  
 Section 14.10 Duties of Trustee Regarding Conversion. 
  
 Neither the Trustee nor any conversion agent shall at any time be under any
duty or responsibility to any Holder of Securities of any series that is convertible into Common Stock of the Company to determine whether any facts exist which may require any adjustment of the conversion price, or with respect to the nature or
extent of any such adjustment when made, or with respect to the method employed, whether herein or in any supplemental indenture, any resolutions of the Board of Directors or written instrument executed by one or more officers of the Company
provided to be employed in making the same. Neither the Trustee nor any conversion agent shall be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock of the Company, or of any securities or
property, which may at any time be issued or delivered upon the conversion of any Securities and neither the Trustee nor any conversion agent makes any representation with respect thereto. Subject to the provisions of Section 6.1, neither the
Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of its Common Stock or stock certificates or other securities or property upon the surrender of any Security for the
purpose of conversion or to comply with any of the covenants of the Company contained in this Article 14 or in the applicable supplemental indenture, resolutions of the Board of Directors or written instrument executed by one or more duly authorized
officers of the Company. 
  
 Section 14.11 Repayment of Certain Funds upon
Conversion. 
  
 Any funds which at any time shall have been
deposited by the Company or on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of, and premium, if any, and interest, if any, on any of the Securities (including, but not limited to, funds deposited for
the sinking fund referred to in Article 12 hereof and funds deposited pursuant to Article 13 hereof) and which shall not be required for such purposes because of the conversion of such Securities as provided in this Article 14 shall after such
conversion be repaid to the Company by the Trustee upon the Company’s written request. 
  

 53 








 ARTICLE 15 
  
 SUBORDINATION OF SECURITIES 
  

Section 15.1 Agreement of Subordination. 
  
 Except as otherwise provided in a supplemental indenture or pursuant to Section 3.1, the Company covenants and agrees, and each Holder of Securities
issued hereunder by its acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to the provisions of this Article 15; and each Person holding any Security, whether upon original issue or upon transfer,
assignment or exchange thereof, accepts and agrees to be bound by such provisions. 
  
 The payment of the principal of, premium, if any, and interest on all Securities (including, but not limited to, the redemption price with respect to the Securities called for redemption in accordance with Article 11
as provided in the Indenture) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior Debt, whether outstanding at the date of this
Indenture or thereafter incurred. 
  
 No provision of this Article
15 shall prevent the occurrence of any default or Event of Default hereunder. 
  
 Section 15.2 Payments to Holders. 
  
  
 No payment shall be made with respect to the principal of, or premium, if any, or interest on the Securities (including, but not limited to, the
redemption price with respect to the Securities to be called for redemption in accordance with Article 11 as provided in the Indenture), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section
15.5, if: 
  
 (i) a default in the payment of
principal, premium, if any, interest, rent or other obligations due on any Senior Debt occurs and is continuing (or, in the case of Senior Debt for which there is a period of grace, in the event of such a default that continues beyond the period of
grace, if any, specified in the instrument or lease evidencing such Senior Debt) (a “Payment Default”), unless and until such default shall have been cured or waived or shall have ceased to exist; or 
  
 (ii) a default, other than a Payment Default, on any
Designated Senior Debt occurs and is continuing that then permits holders of such Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of the default (a “Payment Blockage Notice”) from a holder of Designated
Senior Debt, a Representative of Designated Senior Debt or the Company (a “Non-Payment Default”). 
  
 If the Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no subsequent Payment Blockage Notice shall be effective for purposes
of this Section unless and until at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice. No Non-Payment Default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice. 
  
 The Company may and shall resume payments on and distributions in respect of the Securities upon the earlier of: 
  
 (1) in the case of any Payment Default, the date upon which
the Payment Default is cured or waived or ceases to exist, or 
  
 (2) in the case of a Non-Payment Default, the earlier of (a) the date upon which such Non-Payment Default is cured, waived or ceases to exist or (b) 179 days after the date on which the applicable Payment Blockage
Notice is received by the Trustee, 
  
 unless this Article 15 otherwise prohibits
the payment or distribution at such time. 
  

 54 








 Upon any payment or distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, reorganization, liquidation, receivership or other proceedings,
or upon an assignment for the benefit of creditors or any marshalling of the assets and liabilities of the Company, or otherwise, all amounts due or to become due upon all Senior Debt shall first be paid in full in cash or other payment satisfactory
to the holders of such Senior Debt, or payment thereof in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Debt, before any payment is made on account of the principal of, premium, if any, or
interest on the Securities (except payments made pursuant to Article 4 from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such dissolution, winding-up, liquidation, reorganization, assignment for the
benefit of creditors or the marshalling of assets and liabilities of the Company); and upon any such dissolution, winding-up, liquidation, reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of the
Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, 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 provision of this Article 15, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution,
or by the Holders of the Securities or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Debt (pro rata to such holders on the basis of the respective amounts of Senior Debt held by such holders, or as
otherwise required by law or a court order) or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Debt may have been issued, as their respective
interests may appear, to the extent necessary to pay all Senior Debt in full, in cash or other payment satisfactory to the holders of such Senior Debt, after giving effect to any concurrent payment or distribution to or for the holders of Senior
Debt, before any payment or distribution or provision therefor is made to the Holders of the Securities or to the Trustee. 
  
 For purposes of this Article 15, the words, “cash, property or securities” shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article 15 with respect to the
Securities to the payment of all Senior Debt which may at the time be outstanding; provided that (i) the Senior Debt is assumed by the new corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the
holders of Senior Debt (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company
with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms
and conditions provided for in Article 8 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 15.2 if such other corporation shall, as a part of such consolidation, merger, conveyance or
transfer, comply with the conditions stated in Article 8. 
  
 In
the event of the acceleration of the Securities because of an Event of Default, no payment or distribution shall be made to the Trustee or any Holder of Securities in respect of the principal of, premium, if any, or interest on the Securities
(including, but not limited to, the redemption price with respect to the Securities called for redemption in accordance with Article 11 as provided in the Indenture), except payments and distributions made by the Trustee as permitted by the first or
second paragraph of Section 15.5, until all Senior Debt has been paid in full in cash or other payment satisfactory to the holders of Senior Debt or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the
Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Debt of the acceleration. 
  
 In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in
cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior Debt is paid in full in cash or other
payment satisfactory to the holders of such Senior Debt, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to the holders of such Senior Debt, such payment or distribution shall be held
in trust for the benefit of and shall be paid over or delivered to the holders of Senior Debt or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Debt
may have been issued, 

  

 55 








 
as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Debt remaining unpaid to the extent
necessary to pay all Senior Debt in full in cash or other payment satisfactory to the holders of such Senior Debt, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Debt. 
  
 Nothing in this Section 15.2 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.7. This Section 15.2 shall be subject to the further provisions of Section 15.5. 
  
 Section 15.3 Subrogation of Securities 
  
 Subject to the payment in full of all Senior Debt, the rights of the Holders of the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Debt pursuant to the provisions of this Article 15 (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the
Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Debt to receive payments or distributions of cash, property or securities of the
Company applicable to the Senior Debt until the principal, premium, if any, and interest on the Securities shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Debt of any cash,
property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article 15, and no payment over pursuant to the provisions of this Article 15, to or for the benefit of the holders of
Senior Debt by Holders of the Securities or the Trustee, shall, as between the Company, its creditors other than holders of Senior Debt, and the Holders of the Securities, be deemed to be a payment by the Company to or on account of the Senior Debt;
and no payments or distributions of cash, property or securities to or for the benefit of the Holders of the Securities pursuant to the subrogation provisions of this Article 15, which would otherwise have been paid to the holders of Senior Debt
shall be deemed to be a payment by the Company to or for the account of the Securities. It is understood that the provisions of this Article 15 are and are intended solely for the purposes of defining the relative rights of the Holders of the
Securities, on the one hand, and the holders of the Senior Debt, on the other hand. 
  
 Nothing contained in this Article 15 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Debt, and the Holders of
the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any) and interest on the Securities as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders of the Senior Debt, nor shall anything herein or therein 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 15 of the holders of Senior Debt 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 15, the Trustee, subject to the provisions of Section 6.1, and the Holders of the Securities shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent
or other person making such payment or distribution, delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article 15. 
  
 Section 15.4 Authorization to Effect Subordination. 
  
 Each Holder of a Security by the holder’s acceptance thereof authorizes and directs the Trustee on the holder’s behalf to take such action as
may be necessary or appropriate to effectuate the subordination as provided in this Article 15 and appoints the Trustee to act as the holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding referred to in Section 5.4 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Senior Debt or their representatives are hereby authorized to file an
appropriate claim for and on behalf of the Holders of the Securities. 
  

 56 








 Section 15.5 Notice to Trustee. 
  
 The Company shall give prompt written notice in the form of an Officers’ Certificate to a Responsible Officer of the
Trustee and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies to or by the Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article 15.
Notwithstanding the provisions of this Article 15 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment of monies to or by the Trustee
in respect of the Securities pursuant to the provisions of this Article 15, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an
Officers’ Certificate) or a Representative or a holder or holders of Senior Debt or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 6.1, shall be entitled in all
respects to assume that no such facts exist; provided that if on a date not fewer than two Business Days prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the
payment of the principal of, or premium, if any, or interest on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 15.5, then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such monies 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 on or
after such prior date. 
  
 Notwithstanding anything in this
Article 15 to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Section 4.1, and any such payment shall not be subject to the provisions of Section 15.1 or 15.2. 
  
 The Trustee, subject to the provisions of Section 6.1, shall be entitled to
rely on the delivery to it of a written notice by a Representative or a person representing himself to be a holder of Senior Debt (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of
Senior Debt or a trustee on behalf of any such holder or holders. The Trustee shall not be required to make any payment or distribution to or on behalf of a holder of Senior Debt pursuant to this Article 15 unless it has received satisfactory
evidence as to the amount of Senior Debt 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 15. 
  
 Section 15.6 Trustee’s Relation to Senior Debt. 
  
 The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article 15 in respect of any Senior Debt at any time held by it, to the same extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 
  
 With respect to the holders of Senior Debt, the Trustee undertakes to perform
or to observe only such of its covenants and obligations as are specifically set forth in this Article 15, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and, subject to the provisions of Section 6.1, the Trustee shall not be liable to any holder of Senior Debt (i) for any failure to make any payments or distributions
to such holders or (ii) if it shall pay over or deliver to Holders of Securities, the Company or any other Person money or assets to which any holder of Senior Debt shall be entitled by virtue of this Article 15 or otherwise. 
  
 Section 15.7 No Impairment of Subordination. 
  
 No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the
Company, the Trustee or any Holder of Securities with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with.

 Section 15.8 Certain Conversions/Exchanges Deemed Payment. 
  
 For the purposes of this Article 15 only, (1) the issuance and delivery of
junior securities upon conversion or exchange of Securities in accordance with Article 14 or otherwise (except upon conversion of the Securities in accordance with their terms) shall not be deemed to constitute a payment or distribution on account
of the principal of (or premium, if any) or interest on Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section
14.3), property or securities (other than junior securities) upon conversion or exchange of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section 15.8, the term “junior
securities” means (a) shares of any stock of any class of the Company, or (b) securities of the Company which are subordinated in right of payment to all Senior Debt which may be outstanding at the time of issuance or delivery of such
securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article 15 or elsewhere in this Indenture or in the Securities is intended to or
shall impair, as among the Company, its creditors other than holders of Senior Debt and the Holders of Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 14.

  
 Section 15.9 Article Applicable to Paying Agents. 
  
 If at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for
all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that the first paragraph of Section 15.5 shall not apply to the Company or any Affiliate of the
Company if the Company or such Affiliate acts as Paying Agent. 
  
 The Trustee shall not be responsible for the actions or inactions of any other Paying Agents (including the Company if acting as its own Paying Agent) and shall have no control of any funds held by such other Paying Agents. 
  
 Section 15.10 Senior Debt Entitled to Rely. 
  
 The holders of Senior Debt (including, without limitation, Designated Senior
Debt) shall have the right to rely upon this Article 15, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto. 
  
 Section 15.11 Reliance on Judicial Order or Certificate of Liquidating Agent.

  
 Upon any payment or distribution of assets of the Company
referred to in this Article, the Trustee and the Holders shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such dissolution, winding up, liquidation, reorganization, assignment for the benefit
of creditors or marshalling of assets and liabilities of the Company or bankruptcy, insolvency, receivership or other like 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, for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of
Senior Debt 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.

 Section 15.12 Trust Monies Not Subordinated. 
  
 Notwithstanding anything contained herein to the contrary, payments from money, U.S. Government Obligations and/or Foreign
Government Obligations held in trust under Article 4 or Article 13 by the Trustee for the payment of the principal of, premium, if any, and interest on the Securities shall not be subordinated to the prior payment in full of any Senior Debt of the
Company or subject to the restrictions set forth in this Article 15, and none of the Holders shall be obligated to pay over any such amount to the Company or any holder of Senior Debt of the Company or any other creditor of the Company.
