 The Company may, in the circumstances permitted by the Trust Indenture Act, set any day as
the record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be given or taken by Holders of Securities of such series. With regard to any record date set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date (or their duly appointed agents),
and only such Persons, shall be entitled to give or take the relevant action, whether or not such Holders remain Holders after such record date. With regard to any action that may be given or taken hereunder only by Holders of a requisite principal
amount of Outstanding Securities of any series (or their duly appointed agents) and for which a record date is set pursuant to this paragraph, the Company may, at its option, set an expiration date after which no such action purported to be given or
taken by any Holder shall be effective hereunder unless given or taken on or prior to such expiration date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date (or their duly appointed agents). On
or prior to any expiration date set pursuant to this paragraph, the Company may, on one or more occasions at its option, extend such date to any later date. Nothing in this paragraph shall prevent any Holder (or any duly appointed agent thereof)
from giving or taking, after any such expiration date, any action identical to, or, at any time, contrary to or different from, the action or purported action to which such expiration date relates, in which event the Company may set a record date in
respect thereof pursuant to this paragraph. Nothing in this paragraph shall be construed to render ineffective any action taken at any time by the Holders (or their duly appointed agents) of the requisite principal amount of Outstanding Securities
of the relevant series on the date such action is so taken. Notwithstanding the foregoing or the Trust Indenture Act, the Company shall not set a record date for, and the provisions of this paragraph shall not apply with respect to, any notice,
declaration or direction referred to in the next paragraph. 
 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 5.02, if an Event of Default
with respect to Securities of such series has occurred and is continuing and the Trustee shall not have given such a declaration to the Company, (iii) any request to institute proceedings referred to in Section 5.07(2) or
(iv) any direction referred to in Section 5.12, in each case with respect to Securities of such series. Promptly after any record date is set pursuant to this paragraph, the Trustee shall notify the Company and the Holders of
Outstanding Series of such series of any such record date so fixed and the proposed action. The Holders of Outstanding Securities of such series on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join
in such notice, declaration or direction, whether or not such Holders remain Holders after such record date; provided that, unless such notice, declaration or direction shall have become effective by virtue of Holders of the requisite principal
amount of Outstanding Securities of such series on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such notice, declaration or direction shall automatically and without any
action by any Person be cancelled and of no further effect. Nothing in this paragraph shall be construed to prevent a Holder (or a duly appointed agent thereof) from giving, before or after the expiration of such
90-day period, a notice, declaration or direction contrary to or different from, or, after the expiration of such period, identical to, the notice, declaration or direction to which such record date relates,
in which event a new record date in respect thereof shall be set pursuant to this paragraph. Nothing in this paragraph shall be 

  
 10 









 
construed to render ineffective any notice, declaration or direction of the type referred to in this paragraph given at any time to the Trustee and the Company by Holders (or their duly appointed
agents) of the requisite principal amount of Outstanding Securities of the relevant series on the date such notice, declaration or direction is so given. 
 Without limiting the foregoing, a Holder entitled hereunder to give or 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 different part of such principal amount. 
 Section 1.05 Notices, Etc., to Trustee and Company. 
 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 (which may be via facsimile) 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, 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. 

Section 1.06 Notice to Holders; Waiver. 
 Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage
prepaid, to each Holder affected by such event, at his address as it appears in 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. In any case
where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 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 2.03 Form of Reverse of Security. 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be
issued in one or more series under an Indenture, dated as of             , 2002 (herein called the “Indenture”), between the Company and
            , as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Indebtedness and the Holders of the Securities and of the terms upon which
the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof [if applicable, insert —, limited in aggregate principal amount to
$            ]. 
 [If applicable, insert — Subject to and upon
compliance with the provisions of the Indenture, the Holder of this Security is entitled, at his option, at any time on or before the close of business on
                    , or in case this Security or a portion hereof is called for redemption, then in respect of this Security or such portion hereof
until and including, but (unless the Company defaults in making the payment due upon redemption) not after, the close of business on the 10th calendar day before the Redemption Date, to convert this Security (or any portion of the principal amount
hereof which is $1,000 or an integral multiple thereof), at the principal amount hereof, or of such portion, into fully paid and non-assessable shares (calculated


  
 15 









 
as to each conversion to the nearest 1/100 of a share) of Common Stock of the Company at a conversion price per share of Common Stock equal to
$            per each share of Common Stock (or at the current adjusted conversion price if an adjustment has been made as provided in the Indenture) by surrender of this Security, duly
endorsed or assigned to the Company or in blank, to the Company at its office or agency in                     , accompanied by written notice to the
Company that the Holder hereof elects to convert this Security, or if less than the entire principal amount hereof is to be converted, the portion hereof to be converted, and, in case such surrender shall be made during the period from the close of
business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date (unless this Security or the portion thereof being converted has been called for redemption on a Redemption Date
within such period), also 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 payment or adjustment is to be made on conversion for interest accrued hereon or for dividends on the Common Stock
issued on conversion. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest the Company shall pay a cash adjustment 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 transfer 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 transfer 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 transfer (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).]

 [If applicable, insert — The Securities are subject to redemption at the election of the Holders thereof, in whole or in
part, and in limited circumstances at the election of the Company, in whole, following the occurrence of a Designated Event and a Rating Decline. Such redemptions will be made at a Redemption Price equal to l00% of the principal amount, together
with accrued interest to the Redemption Date, as provided for in Article XIII of the Indenture. [The Securities are not otherwise subject to redemption prior to maturity, and no sinking fund is provided for the Securities.]] 

[If applicable, insert — The Securities of this series are subject to redemption upon not less than 30 days’ notice by mail,
[if applicable, insert — (1) on                     in any year commencing with the year
                    and ending with the year 20

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. 

Subject to the rights of holders of Senior Indebtedness, as set forth in the Indenture, no other reference herein to the Indenture and no

issue date from such series of Outstanding Securities;

securities laws) which are not adverse in any material respect to the Holder of any Outstanding Securities (other than such Add On Securities) and which shall not affect the rights or duties of the Trustee. 

Section 3.02 Denominations.

 Section 3.03 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 President,

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 in or pursuant to one or more Board Resolutions as permitted by Sections 2.01 and 3.01, in


  
 24 









 
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 6.01) shall be fully protected in relying upon, an Opinion of Counsel stating, 
 (1) if the form of such
Securities has been established by or pursuant to Board Resolution as permitted by Section 2.01, 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 3.01,
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 which is not reasonably acceptable to the Trustee. 

Notwithstanding the provisions of Section 3.01 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 3.01 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding
paragraph at or prior to the time of 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 3.09, 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. 

  
 25 









 Section 3.04 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 a like aggregate principal amount and tenor. Until so exchanged the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 

Section 3.05 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 any series at the office or agency 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 a like aggregate principal
amount and tenor. 
 At the option of the Holder, Securities of any series may be exchanged for other Securities of the same
series, of any authorized 
 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 a like aggregate principal amount and tenor, 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 which the Holder making the exchange is entitled to receive. 

  
 26 









 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 his attorney duly authorized in writing. 

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company or Security Registrar 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 3.04, 9.06
or 11.07 not involving any transfer. 
 The Company shall not be required (1) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of that series selected for redemption under Section 11.03 and ending at
the close of business on the day of such mailing, or (2) 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. 

Notwithstanding any other provision in this Indenture, no Global Security may be transferred to, or registered or exchanged for
Securities registered in the name of; any Person other than the Depositary for such Global Security or any nominee thereof, and no such transfer may be registered, unless (1) such Depositary (A) notifies the Company that it is unwilling or
unable to continue as Depositary for such Global Security or (B) has ceased to be a clearing agency registered under the Exchange Act, (2) the Company executes and delivers to the Trustee a Company Order that such Global Security shall be
so transferable, registrable and exchangeable, and such transfers shall be registrable, (3) there shall have occurred and be continuing an Event of Default with respect to the Securities evidenced by such Global Security or (4) there shall
exist such other circumstances, if any, as have been specified for this purpose as contemplated by Section 3.01. Notwithstanding any other provision in this Indenture, a Global Security to which the restriction set forth in the preceding
sentence shall have ceased to apply may be transferred only to, and may be registered and exchanged for Securities registered only in the name or names of, such Person or Persons as the Depositary for such Global Security shall have directed and no
transfer thereof other than such a transfer may be registered. 
 Every Security authenticated and delivered upon registration
of transfer of, or in exchange for or in lieu of, a Global Security to which the restriction set forth in the first sentence of the preceding paragraph shall apply, whether pursuant to this Section, Section 3.04, 3.06, 9.06
or 11.07 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security. 

  
 27 









 Section 3.06 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 exchange for any mutilated Security or in lieu of any
destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities. 
 Section 3.07 Payment of Interest; Interest Rights Preserved. 

Except as otherwise provided as contemplated by Section 3.01 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: 

  
 28 









 (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 mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in
the Security Register, 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 15.02, in the case of any Security which is converted after any Regular Record Date and
on or prior to the next succeeding 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 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 in the case of any Security which is converted, interest whose Stated Maturity is after the date of conversion of such Security, shall not be payable. 

  
 29 









 Section 3.08 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 3.07) 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 3.09 Cancellation. 
 All Securities surrendered for payment, redemption, registration of transfer or exchange or conversion 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 cancelled 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 cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by
the Trustee shall be disposed of by the Trustee in its customary manner. 
 Section 3.10 Computation of Interest. 

Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest on the Securities of
each series shall be computed on the basis of a 360-day year of twelve 30-day months. 
 Section 3.11 CUSIP Numbers. 
 The Company in issuing the
Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation
is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any changes in the “CUSIP” numbers. 
 ARTICLE IV

If an Event of Default 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 (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of
the principal amount of such Securities as may be specified in the terms thereof) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become immediately due and payable. 
 At any time after such

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,

thereon. 

  
 33 









 Section 5.03 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 necessary 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 5.04 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 6.07. 

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 5.05 Trustee May Enforce Claims Without Possession of Securities. 

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been
recovered. 
 Section 5.06 Application of Money Collected. 

Subject to Article XVI, 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 6.07;

 SECOND: To the payment of the amounts then due and unpaid for principal of and any premium 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 and interest, respectively;

 Section 5.07 Limitation on Suits. 
 No Holder of any Security
of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or 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 not less than 25% 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 satisfactory to it 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 

  
 35 









 (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.

and to Convert. 
 Notwithstanding any other provision in this Indenture, but subject to Article XVI, 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 3.07) interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to convert such Security in accordance with Article XV and to institute suit for the enforcement of any such payment and right to convert, and such rights shall not be
impaired without the consent of such Holder. 
 Section 5.09 Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be
restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 

Section 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 3.06, 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


  
 36 









 
time to time, and as often as may be deemed expedient, by the Trustee 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, 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with
such direction, and 
 (3) subject to the provisions of Section 6.01, the Trustee shall have the right to decline to
follow any such direction if the Trustee in good faith share, by a Responsible Officer or Officers of the Trustee, determine, and the Trustee shall have received a legal opinion stating, that the proceedings so directed would involve the Trustee in
personal liability. 
 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 a default 
 (1) in the payment of the principal of or any premium or interest on any Security of such series, or 
 (2) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

 Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have
been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 Section 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 apply to any suit instituted by the Trustee,
to any suit instituted by any Holders of the Securities, or group of Holders of the Securities, holding in the aggregate more than 10% of principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder of the
Outstanding Securities for the enforcement of the payment of principal of or interest on any Outstanding 

  
 37 









 
Securities held by such Holder, on or after the respective due dates expressed in such Outstanding Securities, and provided, further, that neither this Section nor the Trust Indenture Act shall

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.

 The Trustee hereby accepts the trust imposed upon it by this Indenture and covenants and agrees to perform the same, as herein expressed. 
 Section 6.01 Duties of Trustee. 
 (A) If an
Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the

 38 









 (i) This paragraph does not limit the effect of paragraph (b) of this

investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such
investigation. 

  
 39

or powers vested in it by this Indenture at the request, order or direction of any of the Holders, pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to
it against the costs, expenses and liabilities which may be incurred therein or thereby.

 (H) The Trustee shall not be deemed to have notice of any Event of Default unless a Responsible Officer of the
Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture.

 (I) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without
limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

 If an Event of Default with respect to Securities of any series occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder of Securities of such series notice of the
uncured Event of Default within 90 days after such Event of Default occurs. Except in the case of an Event of Default in payment of principal (or premium, if any) of, or interest on, any Security, the Trustee may withhold the notice if and so long

Holders shall be mailed to the Company and filed with the Commission and each stock exchange, if any, on which the Securities are listed. 

Section 6.07 Compensation and Indemnity. 
 The Company shall pay to the Trustee from time to time such compensation for its services as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not
be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable disbursements, expenses and advances incurred or made by it. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee’s agents, accountants, experts and counsel. 
 The Company shall
indemnify each of the Trustee (in its capacity as Trustee) and any predecessor Trustee and each of their respective officers, directors, attorneys-in-fact and agents
for, and hold it harmless against, any claim, demand, expense (including but not limited to reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel), loss, charges (including taxes (other than taxes based upon
the income of the Trustee)) or liability incurred by them without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust and their rights or duties hereunder including the reasonable
costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the
Trustee for which it may seek indemnity. The Company shall defend the claim and the Trustee shall provide reasonable cooperation at the Company’s expense in the defense. The Trustee may have separate counsel and the Company shall pay the

liability to the extent incurred by the Trustee as determined by a court of competent jurisdiction to have been caused by its own negligence, bad faith or willful misconduct. 
 To secure the Company’s payment obligations in this Section 6.07, the Trustee shall have a lien prior to the Securities on all assets held or collected by the Trustee, in its capacity as


  
 41

 The Company’s obligations under this

Indenture under any Bankruptcy Law. 
 Section 6.08 Replacement of Trustee. 

The Trustee may resign at any time with respect to the Securities of one or more series by so notifying the Company in writing. The
Holder or Holders of a majority in principal amount of the outstanding Securities of a series may remove the Trustee with respect to Securities of such series by so notifying the Company and the Trustee in writing and may appoint a successor trustee
with respect to Securities of such series with the Company’s consent. The Company may remove the Trustee if: 
 (1) the
Trustee fails to comply with Section 6.10; 
 (2) the Trustee is adjudged bankrupt or insolvent; 

(3) a receiver, custodian, or other public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee, with respect to the Securities of one or more series, for any reason, the Company shall promptly appoint a successor
Trustee, with respect to Securities of that or those series. Within one year after the successor Trustee with respect to a series of Securities takes office, the Holder or Holders of a majority in principal amount of the Securities of such series
may appoint a successor Trustee with respect to such series to replace the successor Trustee appointed by the Company. 
 A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that and provided that all sums owing to the Trustee provided for in Section 6.07 have been paid, the
retiring Trustee shall transfer all property held by it as Trustee with respect to such series of Securities to the successor Trustee, subject to the lien provided in Section 6.07, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee with respect to one or more series of Securities shall mail notice of its succession to each Holder of
Securities of that or those series. 

  
 42 









 If a successor Trustee with respect to a series of Securities does not take office within 60
days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holder or Holders of at least 10% in principal amount of the outstanding Securities of that series may petition at the expense of the Company any court
of competent jurisdiction for the appointment of a successor Trustee with respect to such series. 
 If the Trustee fails to
comply with Section 6.10, any Holder of Securities of a series may petition any court of competent jurisdiction for the removal of the Trustee with respect to such series and the appointment of a successor Trustee with respect to such
series. 
 Notwithstanding replacement of the Trustee pursuant to this Section 6.08, the Company’s obligations
under Section 6.07 shall continue for the benefit of the retiring Trustee. 
 Section 6.09 Successor Trustee by
Merger, Etc. 
 If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its
corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee.

the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of
Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series. If less than all of the Securities of such series and of a specified tenor are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 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.

 If any Security selected for partial redemption is converted in part before termination of the conversion right with respect

series are to be redeemed, the identification (and, in the case of partial redemption of any Securities, the principal amounts) of the particular Securities to be redeemed,

 Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent 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 other than any Securities called for redemption on that date which have been converted prior to the date of such deposit. 

If any Security called for redemption is converted, any money deposited with the Trustee or with any Paying Agent or so segregated and
held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last paragraph of Section 3.07) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such trust. 
 Section 11.06 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 3.01, installments of interest whose Stated Maturity is on or prior to the Redemption Date shall 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 3.07. 
 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 11.07 Securities Redeemed in Part. 

Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment thereof (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 his 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.

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 the Securities of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such
Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 

Section 12.03 Redemption of Securities for Sinking Fund. 
 Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing
sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of
that series pursuant to Section 12.02 and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 11.03 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 11.04. Such

 ARTICLE XIII 
 REDEMPTION UPON A DESIGNATED EVENT AND A RATING DECLINE 
 Section 13.01
Redemption by Holders. 
 Subject to Section 3.01(14), in the event that there occurs (a) a Designated
Event (as hereinafter defined) at any time on or prior to Maturity, and (b) a Rating Decline (as hereinafter defined), each Holder of a Security that is of a series to which this Article XIII is applicable (for purposes of this
Article XIII, a “Subject Security”) shall have the right, at the Holder’s option, to require the Company to redeem all or any portion (which shall be $1,000 or an integral multiple thereof) of such Subject Security on
the date that is 90 days after the last to occur of public notice of the occurrence of the Designated Event and the Rating Decline, at a redemption price equal to 100% of the principal amount thereof, plus accrued interest to the Redemption Date.

 On or before the twenty-eighth day after the last to occur of public notice of the occurrence of the Designated Event and the
Rating Decline, the Company is obligated to notify the Trustee of such events, and promptly thereafter to mail, or cause to be mailed first-class, postage prepaid, to each Holder of any Subject Securities, at the address of such Holder appearing in
the Security Register, a notice regarding the Designated Event, the Rating Decline, and the redemption right. The notice shall include the Redemption Date, the date by which the redemption right must be exercised, the Redemption Price, and the
procedure which the Holder must follow to exercise this right. 
 To exercise this right, the Holder of such Subject Securities
must deliver on or before a date selected by the Company, which date shall be not more than 10 days prior to the Redemption Date, written notice to the Company (or an agent designated by the Company for such purpose) of the Holder’s exercise of
such right, together with the Subject Securities with respect to which the right is being exercised, duly endorsed or assigned to the Company or in blank. Such written notice by a Holder shall, unless otherwise required by law, be irrevocable.

 As used herein, a “Designated Event” shall be deemed to have occurred at such a time as any
“person” or “group” (as such terms are used for purposes of Sections 13(d) and 14(d) of the Exchange Act, whether or not applicable) becomes the “beneficial owner” (as the term is used in Rules 13d-3 and 13d-5 under the Exchange Act, whether or not applicable, except that a person shall be deemed to have “beneficial ownership” of all shares that any such
person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 50% of the total voting power entitled to vote in the election of directors of the Company;
provided, however, that a Designated Event shall not be deemed to have occurred (i) as a result of the formation of such a “group” or the acquisition of shares of Capital Stock of the Company by such group if such group includes
existing Affiliates and/or persons who beneficially own in the aggregate, as of the date of this Indenture, 20% or more of the outstanding shares of Capital Stock of the Company on the date of this Indenture, or (ii) by virtue of the Company,
any Subsidiary, any employee stock ownership plan or any other employee benefit plan of the Company or of any Subsidiary, or any other person holding Capital Stock of the Company for or pursuant to the terms of any such employee benefit plan,
becoming a beneficial owner, directly or indirectly, of more than 50% of the total voting power entitled to vote in the election of directors of the Company. 

  
 53 









 As used herein, a “Rating Decline” shall be deemed to have occurred if on any date
within the 90-day period following public notice of the occurrence of a Designated Event (which 90-day period shall be extended with respect to either Rating Agency (as
hereinafter defined) for so long as the rating of the Securities is under publicly announced consideration for possible downgrade relating to such Designated Event by such Rating Agency) (i) in the event the Securities are rated by one Rating
Agency or by both Rating Agencies on the Rating Date (as hereinafter defined) as Investment Grade (as hereinafter defined), the rating of the Securities by such Rating Agency or by either of such Rating Agencies (as the case may be) shall be below
Investment Grade; or (ii) in the event the Securities are rated by both Rating Agencies on the Rating Date below Investment Grade, the rating of the Securities by either Rating Agency shall be at least one Full Rating Category (as hereinafter
defined) below the rating of the Securities by such Rating Agency on the Rating Date. 
 As used herein, “Rating
Agency” shall mean Standard & Poor’s Corporation and its successors (“S&P”), and Moody’s Investors Service and its successors (“Moody’s”), or if S&P or Moody’s or both
shall not make a rating on the Securities publicly available, a nationally recognized statistical rating organization or organizations, as the case may be, selected by the Company which shall be substituted for S&P or Moody’s or both, as
the case may be; “Investment Grade” shall mean BBB- or higher by S&P or Baa3 or higher by Moody’s or the equivalent of such ratings by S&P or Moody’s or by any other Rating Agency
selected as provided above, and “Rating Date” shall mean the date which is 121 days prior to public notice of the occurrence of a Designated Event. 
 As used herein, the term, “Full Rating Category” shall mean (i) with respect to S&P, any of the following categories BB, B, CCC, CC, and C; (ii) with respect to
Moody’s, any of the following categories: Ba, B, Caa, Ca, and C; and (iii) with respect to any other Rating Agency, the equivalent of any such category of S&P or Moody’s used by such other Rating Agency. In determining whether the
rating of the Securities has decreased by the equivalent of one Full Rating Category, gradation within Full Rating Categories (+ and - for S&P, 1, 2, and 3 for Moody’s; or the equivalent gradation for another Rating Agency) shall be taken
into account (e.g., with respect to S&P, a decline in a rating from BB+ to BB-, or from BB to B+, will constitute a decrease of less than one Full Rating Category). 

Section 13.02 Redemption by Company. 
 In the event the aggregate principal amount of the Subject Securities that are surrendered for redemption on any such Redemption Date is a least 90% of the aggregate principal amount of the Subject
Securities Outstanding at the close of business on the day next preceding such Redemption Date, the remaining Subject Securities not so redeemed will be subject to redemption as a whole, at the Company’s option, upon not less than 30 days’
notice mailed to each Holder at the address of such Holder appearing in the Security Register, on a date of redemption selected by the Company that is within 60 days after such Redemption Date, at a Redemption Price equal to 100% of the principal
amount, plus accrued interest to such date of redemption selected by the Company. 

  
 54 









 Section 13.03 Other Provisions. 

With respect to any redemption at the option of the Holders of Securities, as hereinabove provided, (x) the first clause of
Section 11.06 shall read as follows: “Notice by the Holder of such Holder’s exercise of the redemption right having been duly given,” and (y) if any Security delivered by the Holder upon exercise of the redemption
right is, at the option of the Holder, to be redeemed in part only, the written notice delivered by the Holder to the Company as aforesaid shall state the principal amount of the Security which is to be redeemed. 

Notwithstanding the foregoing, the Holders shall not have the redemption right described above if, prior to the occurrence of the
Designated Event, the Company has effected a defeasance or covenant defeasance of the Securities as provided in Article XIV. 
 ARTICLE XIV 
 DEFEASANCE AND COVENANT DEFEASANCE 

Section 14.01 Company’s Option to Effect Defeasance or Covenant Defeasance. 

The Company may elect, at its option by Board Resolution at any time, to have either Section 14.02 or
Section 14.03 applied to the Outstanding Securities of any series designated pursuant to Section 3.01 as being defeasible pursuant to this Article XIV (hereinafter called a “Defeasible Series”), upon
compliance with the conditions set forth below in this Article XIV; provided that Section 14.02 shall not apply to any series of Securities that is convertible into Common Stock as provided in Article XV or convertible into
or exchangeable for any other securities pursuant to Section 3.01(18). 
 Section 14.02 Defeasance and Discharge.

 Upon the Company’s exercise of the option provided in Section 14.01 to have this Section 14.02
applied to the Outstanding Securities of any Defeasible Series and subject to the proviso to Section 14.01, the Company shall be deemed to have been discharged from its obligations with respect to the Outstanding Securities of such
series as provided in this Section on and after the date the conditions set forth in Section 14.04 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 the Outstanding Securities of such series and to have satisfied all its other obligations under the Securities of such series and this Indenture insofar as the Securities of such
series 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 Securities of such series to receive, solely from the trust fund described in Section 14.04 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities
of such series when payments are due, (2) the Company’s obligations with respect to the Securities of such series under Sections 3.04, 3.05, 3.06, [the covenant requiring the Company to maintain an office or agency for
the payment of Securities] and [the covenant requiring the Company to hold in trust funds for the payment of Securities], (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article XIV.
Subject to compliance with this Article XIV, the Company may exercise its 

  
 55 









 
option provided in Section 14.01 to have this Section 14.02 applied to the Outstanding Securities of any Defeasible Series notwithstanding the prior exercise of its option
provided in Section 14.01 to have Section 14.03 applied to the Outstanding Securities of such series. 

Section 14.03 Covenant Defeasance. 
 Upon the Company’s exercise of the option provided in Section 14.01 to have this Section 14.03 applied to the Outstanding Securities of any Defeasible Series, (1) the
Company shall be released from its obligations under Section 8.01, and [the covenants requiring the Company to maintain its corporate existence and to satisfy its tax obligations and certain other claims, and any negative covenants
applicable to the Securities], and Article XIII, and (2) the occurrence of any event specified in Sections 5.01(3), 5.01(4) (with respect to Section 8.01, [the covenants requiring the Company to maintain its
corporate existence and to satisfy its tax obligations and certain other claims, and any negative covenants applicable to the Securities], and Article XIII), 5.01(5) and 5.01(8) shall be deemed not to be or result in an Event of
Default, in each case with respect to the Outstanding Securities of such series as provided in this Section on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter called “Covenant
Defeasance”). For this purpose, such Covenant Defeasance means that 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 5.01(4)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other
document, but the remainder of this Indenture and the Securities of such series shall be unaffected thereby. 
 Section 14.04
Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the conditions to application of either
Section 14.02 or Section 14.03 to the Outstanding Securities of any Defeasible Series: 
 (1) The
Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee that satisfies the requirements contemplated by Section 6.09 and agrees to comply with the provisions of this Article XIV
applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of Outstanding Securities of such series, (A) money in an
amount, or (B) U.S. Government Obligations that 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, money in an
amount, or (C) 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 the Securities of such series on the respective Stated Maturities, in accordance with the terms of
this Indenture and the Securities of such series. As used herein, “U.S. Government Obligation” means (x) any security that is (i) a direct obligation of the United States of America for the payment of which full faith and
credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of


  
 56 









 
which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of
the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act of 1933, as amended) as custodian with respect to any U.S. Government Obligation specified in Clause (x) and held
by such custodian for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any such U.S. Government Obligation, provided that (except as required by law) such custodian is not
authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by
such depositary receipt. 
 (2) In the case of an election under Section 14.02, the Company shall have delivered to
the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date first set forth hereinabove, 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 the Outstanding Securities of such series 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 the Securities of such series 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 case of an election under
Section 14.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Securities of such series will not recognize gain or loss for Federal income tax purposes as a result
of the deposit and Covenant Defeasance to be effected with respect to the Securities of such series 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 and
Covenant Defeasance were not to occur. 
 (4) The Company shall have delivered to the Trustee an Officer’s Certificate to
the effect that the Securities of such series, if then listed on any securities exchange, will not be delisted as a result of such deposit. 
 (5) No Event of Default or event that (after notice or lapse of time or both) would become an Event of Default shall have occurred and be continuing at the time of such deposit or, with regard to any
Event of Default or any such event specified in Sections 5.01(6) and (7), 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). 
 (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the
meaning of the Trust 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, any other agreement or instrument to which the Company is a party or by which it is bound. 

  
 57 









 (8) The Company shall have delivered to the Trustee an Officer’s Certificate and an
Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
 (9) 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 of 1940, as amended,
unless such trust shall be qualified under such Act or exempt from regulation thereunder. 
 Section 14.05 Deposited Money and
U.S Government Obligations to be Held in Trust; Other Miscellaneous Provisions. 
 All money and U.S. Government Obligations
(including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 14.06, the Trustee and any such other trustee are referred to collectively as the
“Trustee”) pursuant to Section 14.04 in respect of the Securities of any Defeasible Series shall be held in trust and applied by the Trustee, in accordance with the provisions of the Securities of such series 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 Securities of such series, 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. 
 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 deposited pursuant to Section 14.04 or the
principal and interest received in respect thereof other than any such tax, fee or other charge that by law is for the account of the Holders of Outstanding Securities. 
 Anything in this Article XIV to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by
it as provided in Section 14.04 with respect to Securities of any Defeasible Series that, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Defeasance or Covenant Defeasance with respect to the Securities of such series. 

Section 14.06 Reinstatement. 
 If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article XIV with respect to the Securities of any series by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities of such series shall be revived and reinstated as though no deposit had occurred
pursuant to this Article XIV with respect to Securities of such series until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 14.05 with respect to Securities of such
series in accordance with this Article XIV; provided, however, that if the Company makes any payment of principal of or any premium or interest on any Security of such series following 


  
 58 









 
the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of Securities of such series to receive such payment from the money so held in trust.

 ARTICLE XV 
 CONVERSION OF SECURITIES 
 Section 15.01 Applicability; Conversion Privilege
and Conversion Price. 
 Securities of any series which are convertible into Common Stock of the Company shall be
convertible in accordance with their terms and (except as otherwise specified as contemplated by Section 3.01 for Securities of any series) in accordance with this Article. 

Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Security or any portion of
the outstanding principal amount thereof which is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into fully paid and nonassessable shares (calculated as to each conversion to
the nearest 1/100 of a share) of Common Stock of the Company at the conversion price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall expire at the close of business on the date specified for
Securities of such series. In case a Security or portion thereof is called for redemption at the election of the Company, such conversion right in respect of the Security or portion so called shall expire at the close of business on the 10th
calendar day before the Redemption Date, unless the Company defaults in making the payment due upon redemption. 
 The price at
which shares of Common Stock shall be delivered upon conversion (herein called the “conversion price”) shall be the price specified in relation to Securities of such series pursuant to Section 3.01, as it shall be adjusted in
certain instances as provided in this Article. 
 Section 15.02 Exercise of Conversion Privilege. 

In order to exercise the conversion privilege, the Holder of any Security to be converted shall surrender such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency of the Company maintained for that purpose, accompanied by written notice to the Company (which shall be substantially in the form set forth in Section 2.03) at such office or
agency that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Securities surrendered for conversion during the period from the close of business
on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except in the case of Securities or portions thereof which have been called for redemption on a Redemption Date
within such period) 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 Securities being surrendered for conversion. Subject to the
provisions of Section 3.07 relating to the payment of Defaulted Interest by the Company, the interest payment with respect to a Security called for redemption on a Redemption Date during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall be payable on such Interest Payment Date to the Holder of such Security at the close of business on such Regular Record Date


  
 59 









 
notwithstanding the conversion of such Security after such Regular Record Date and prior to such Interest Payment Date, and the Holder converting such Security need not include a payment of such
interest payment amount upon surrender of such Security for conversion. Except as provided in the preceding sentence and subject to the final paragraph of Section 3.07, no payment or adjustment shall be made upon any conversion on
account of any interest accrued on the Securities surrendered for conversion or on account of any dividends on the Common Stock issued upon conversion. 
 Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at
such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common
Stock at such time. As promptly as practicable on or after the conversion date, the Company shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock issuable upon conversion,
together with payment in lieu of any fraction of a share, as provided in Section 15.03. 
 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 the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in
aggregate principal amount equal to the unconverted portion of the principal amount of such Security. 
 Section 15.03 Fractions
of Shares. 
 No fractional shares of Common Stock shall be issued upon conversion of Securities. 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 thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions
thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such
fraction in an amount equal to the same fraction of the daily closing price per share of Common Stock (consistent with Section 15.04(6) below) at the close of business on the day of conversion. 

Section 15.04 Adjustment of Conversion Price. 
 (1) In case the Company shall pay or make a dividend or other distribution on any class of capital stock of the Company in Common Stock, the conversion price in effect at the opening of business on the
day following the date fixed for determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to
become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (1), the number of shares of Common Stock at any time outstanding


  
 60 









 
shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company
will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. 
 (2) In case
the Company shall issue rights or warrants to all holders of its Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share (determined as provided in paragraph
(6) of this Section) of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights or warrants (other than pursuant to a dividend reinvestment plan), the conversion price in effect at the opening of
business on the day following the date fixed for such determination shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such current market price
and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase, such reduction to
become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (2), the number of shares of Common Stock at any time outstanding shall not include shares held
in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not issue any rights or warrants in respect of shares of Common Stock held in
the treasury of the Company. 
 (3) In case outstanding shares of Common Stock shall be subdivided into a greater number of
shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and, conversely, in case outstanding shares of Common
Stock shall each be combined into a smaller number of shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased,
such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 

(4) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or
assets (including securities, but excluding any rights or warrants referred to in paragraph (2) of this Section, any dividend or distribution paid in cash out of the earned surplus of the Company and any dividend or distribution referred to in
paragraph (1) of this Section), the conversion price shall be adjusted so that the same shall equal the price determined by multiplying the conversion price in effect immediately prior to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution by a fraction of which the numerator shall be the current market price per share (determined as provided in paragraph (6) of this Section) of the Common Stock on the date fixed
for such determination less the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution filed with the Trustee) of the portion of the assets or evidences of
indebtedness so distributed applicable to one 

  
 61 









 
share of Common Stock and the denominator shall all be such current market price per share of the Common Stock, such adjustment to become effective immediately prior to the opening of business on
the day following the date fixed for the determination of stockholders entitled to receive such distribution. 
 (5) The
reclassification of Common Stock into securities other than Common Stock (other than any reclassification upon a consolidation or merger to which Section 15.11 applies) shall be deemed to involve (a) a distribution of such
securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be “the date fixed for the determination of stockholders entitled to receive such distribution” and the
“date fixed for such determination” within the meaning of paragraph (4) of this Section), and (b) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such
reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be “the day upon which such subdivision becomes effective” or “the day
upon which such combination becomes effective”, as the case may be, such “the day upon which such subdivision or combination becomes effective” within the meaning of paragraph (3) of this Section). 

(6) For the purpose of any computation under paragraphs (2) and (4) of this Section, the current market price per share of
Common Stock on any day shall be deemed to be the average of the daily closing prices for the five consecutive trading days (i.e., Business Days on which the Common Stock is traded) selected by the Board of Directors commencing not more than 20
trading days before, and ending not later than, the earlier of the day in question and the day before the “ex” date with respect to the issuance or distribution requiring such computation. For this purpose, the term “‘ex’
date”, when used with respect to any issuance or distribution, shall mean the first date on which the Common Stock trades regular way on the applicable exchange or in the applicable market without the right to receive such issuance or
distribution. The closing price for each day shall be the reported last sale price regular way or, in case no such reported sale takes place on such day, the average of the reported closing bid and asked prices regular way, in either case on the New
York Stock Exchange or, if the Common Stock is not listed or admitted to trading on such Exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading or, if not listed or admitted to trading on
any national securities exchange, on the Nasdaq Stock Market or, if the Common Stock is not listed or admitted to trading on any national securities exchange or quoted on the Nasdaq Stock Market, the average of the closing bid and asked prices in
the over-the-counter market as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose. 

(7) The Company may make such reductions in the conversion price, in addition to those required by paragraphs (1), (2), (3) and
(4) of this Section, as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or
subscribe for stock or from any event treated as such for income tax purposes or for any other reasons. The Company shall have the power to resolve any ambiguity or correct any error in this paragraph (7) and its actions in so doing shall be
final and conclusive. 

  
 62 









 (8) No adjustment in the conversion price shall be required unless such adjustment would
require an increase or decrease of at least one percent in such conversion price; provided, however, that any adjustments which by reason of this paragraph (8) is not required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Article shall be made to the nearest cent or to the nearest 1/100 of a share, as the case may be. 
 Section 15.05 Notice of Adjustments of Conversion Price. 

Whenever the conversion price is adjusted as herein provided: 

(A) the Company shall compute the adjusted conversion price in accordance with Section 15.04 and shall prepare
a certificate signed by the Treasurer of the Company 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; and 
 (B) a notice stating that the conversion price has
been adjusted and setting forth the adjusted conversion price shall forthwith be required, and as soon as practicable after it is required, such notice shall be mailed by the Company to all Holders at their last addresses as they shall appear in the
Security Register. 
 Section 15.06 Notice of Certain Corporate Action. 

In case: 
 (A) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its earned surplus; or 

(B) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or
purchase any shares of capital stock of any class or of any other rights; or 
 (C) 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 stockholders of the
Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 

(D) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; 

then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Securities, 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 (a) or (b) above) prior to the applicable record or effective date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders


  
 63 









 
of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined, or (y) the date on which such reclassification, consolidation, merger, share
exchange, sale, transfer, 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, transfer, dissolution, liquidation or winding up. Neither the failure to give such notice nor any defect therein shall affect the
legality or validity of the proceedings described in clauses (a) through (d) of this Section 15.06. If at the 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. 
 Not less than seven days prior to any date fixed for the determination of stockholders entitled to
receive such distribution, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Securities, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Security
Register, a notice stating the date on which the such determination is to be made, and briefly describing the import thereof. If at the 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 15.07 Company to Reserve Common Stock. 

The Company shall at all times reserve and keep available 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 then issuable upon the conversion of all Outstanding Securities. 

Section 15.08 Taxes on Conversions. 
 The Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares of 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 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 15.09 Covenant as to Common Stock. 
 The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and, except as provided in
Section 15.08, the Company will pay all taxes, liens and charges with respect to the issue thereof. 
 Section 15.10
Cancellation of Converted Securities. 
 All Securities delivered for conversion shall be delivered to the Trustee to be

 Section 15.11 Provisions in Case of Consolidation, Merger or Sale of Assets. 

In case of any consolidation of the Company with, or merger of the Company into, any other Person, any merger of another Person 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 sale or transfer 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 convertible Security then
outstanding shall have the right thereafter, during the period such Security shall be convertible as specified in Section 15.01, to convert such Security only into the kind and amount of securities, cash and other property receivable
upon such consolidation, merger, sale or transfer 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, sale or transfer, assuming such
holder of Common Stock of the Company failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer (provided that if the kind or
amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer is not the same for each share of Common Stock of the Company in respect of which such rights of election shall not have been exercised
(“non-electing share”), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer by 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. The above provisions of this Section
shall similarly apply to successive consolidations, mergers, sales or transfers. 
 Section 15.12 Responsibility of Trustee.

 Neither the Trustee nor any conversion agent shall at any time be under any duty or responsibility to any Holder of
Securities to determine whether any fact exists 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, or herein or in any
supplemental indenture provided to be employed, in making the same. Neither the Trustee nor any conversion agent shall be accountable with respect to the registration, validity or value (or the kind or amount) of any shares of Common Stock, or of
any securities or property, which may at any time be issued or delivered upon the conversion of any Security; and neither the Trustee nor any conversion agent makes any representation with respect thereto. Neither the Trustee nor any conversion
agent shall be responsible for any failure of the Company to issue or transfer or deliver any Common Stock or stock certificates or other securities or property or to make any cash payment 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 XV.

 ARTICLE XVI 
 SUBORDINATION OF SECURITIES 
 Section 16.01 Securities Subordinate to Senior
Indebtedness. 
 The Company covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise
covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article, the indebtedness represented by the Securities and the payment of the principal of (and premium, if any) and interest on each and all of the
Securities are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness. 

Section 16.02 Payment Over of Proceeds Upon Dissolution, Etc. 

In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other
similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or
not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of the Company, then and in any such event the holders of Senior Indebtedness shall be entitled to
receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness, or provision shall be made for such payment in money or money’s worth, before the Holders of the Securities are entitled to receive any
payment on account of principal of (or premium, if any) or interest on the Securities, and to that end the holders of Senior Indebtedness shall be entitled to receive, for application to the payment thereof, any payment or distribution of any kind
or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Securities in any such case, proceeding, dissolution, liquidation or other winding up or event. 

In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Security shall have
received any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, before all Senior Indebtedness is paid in full or payment thereof provided for, and if such fact shall, at or prior to
the time of such payment or distribution, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of the Company for application to the payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. 
 For purposes of this Article only, 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 which are subordinated in right of payment to all Senior Indebtedness which may at the time be outstanding to substantially the same extent as, or to a greater
extent than, the Securities are so subordinated as provided in this Article. The consolidation of the Company with, or the merger 

  
 66 









 
of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or transfer of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article VII shall not be deemed a dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of the Company for the
purposes of this Section if the Person formed by such consolidation or into which the Company is merged or which acquires by conveyance or transfer such properties and assets substantially as an entirety, as the case may be, shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article VIII. 
 Section 16.03
Prior Payment to Senior Indebtedness Upon Acceleration of Securities. 
 In the event that any Securities are declared
due and payable before their Stated Maturity, then and in such event the holders of Senior Indebtedness outstanding at the time such Securities so become due and payable shall be entitled to receive payment in full of all amounts due or to become
due on or in respect of such Senior Indebtedness, or provision shall be made for such payment in money or money’s worth, before the Holders of the Securities are entitled to receive any payment by the Company on account of the principal of (or
premium, if any) or interest on the Securities or on account of the purchase or other acquisition of Securities; provided, however, that nothing in this Section shall prevent the satisfaction of any sinking fund payment in accordance with Article
XII by delivering and crediting pursuant to Section 12.02 Securities which have been acquired (upon redemption or otherwise) prior to such default or which have been converted pursuant to Article XV. 

In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of any Security
prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such payment shall be paid over
and delivered forthwith to the Company. 
 The provisions of this Section shall not apply to any payment with respect to which
Section 16.02 would be applicable. 
 Section 16.04 No Payment When Senior Indebtedness in Default. 

(a) In the event and during the continuation of any default in the payment of principal of (or premium, if any) or interest on any Senior
Indebtedness beyond any applicable grace period with respect thereto, or in the event that any event of default with respect to any Senior Indebtedness shall have occurred and be continuing and shall have resulted in such Senior Indebtedness
becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured or waived or shall have ceased to exist and such acceleration shall
have been rescinded or annulled, or (b) in the event any judicial proceeding shall be pending with respect to any such default in payment or event of default, then no payment shall be made by the Company on account of principal of (or premium,
if any) or interest on the Securities or on account of the purchase or other acquisition of Securities; provided, however, that nothing in this Section shall prevent the satisfaction of any sinking fund payment in accordance with Article XII
by 

  
 67 









 
delivering and crediting pursuant to Section 12.02 Securities which have been acquired (upon redemption or otherwise) prior to such default or which have been converted pursuant to
Article XV. 
 In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee
or the Holder of any Security prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event
such payment shall be paid over and delivered forthwith to the Company. 
 The provisions of this Section shall not apply to any
payment with respect to which Section 16.02 would be applicable. 
 Section 16.05 Payment Permitted If No
Default. 
 Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent the
Company, at any time except during the pendency of any case, proceeding, dissolution, liquidation or other winding up, assignment for the benefit of creditors or other marshalling of assets and liabilities of the Company referred to in
Section 16.02 or under the conditions described in Section 16.03 or 16.04, from making payments at any time of principal of (and premium, if any) or interest on the Securities. 

Section 16.06 Subrogation to Rights of Holders of Senior Indebtedness. 

Subject to the payment in full of all Senior Indebtedness, the Holders of the Securities shall be subrogated (equally and ratably with
the holders of all indebtedness of the Company which by its express terms is subordinated to 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 such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of (and premium, if any) and interest on the Securities shall be paid in
full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness 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, and no payments over pursuant to the provisions of this Article to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Indebtedness and
the Holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness. 

Section 16.07 Provisions Solely to Define Relative Rights. 
 The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities on the one hand and the holders of Senior Indebtedness on the
other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional (and which, subject to the rights under this Article of the holders of Senior Indebtedness, is intended to rank equally with all other general


  
 68 









 
obligations of the Company), 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 (b) affect the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior Indebtedness; or (c) 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 of the holders of Senior Indebtedness to receive cash, property and securities otherwise
payable or deliverable to the Trustee or such Holder. 
 Section 16.08 Trustee to Effectuate Subordination. 

Each holder of a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes.

 Section 16.09 No Waiver of Subordination Provisions. 

No right of any present or future holder of any Senior Indebtedness 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 non-compliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 
 Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the
Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Securities to the holders
of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner Senior
Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness;
(iii) release any Person liable in any manner for the collection of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company and any other Person. 

Section 16.10 Notice to Trustee. 
 The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Securities.
Notwithstanding the provisions of this Article 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 to or by the Trustee in respect of
the Securities, unless and until the Trustee shall have received written notice thereof from the Company or a holder of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such


  
 69 









 
written notice, the Trustee, subject to the provisions of Section 6.01, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee
shall not have received the notice provided for in this Section at least three Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal
of (and premium, if any) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money
was received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to such date. 
 Subject to the provisions of Section 6.01, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee therefor) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to
the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
 Section 16.11 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, subject to the provisions of Section 6.01, and the Holders of the Securities shall be
entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up 

or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian,
assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article.

 Section 16.12 Trustee Not Fiduciary for Holders of Senior Indebtedness. 

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such
holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this
Article or otherwise. 

  
 70 









 Section 16.13 Rights of Trustee as Holder of Senior Indebtedness; Preservation of
Trustee’s Rights. 
 The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

 Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.07.

 Section 16.14 Article Applicable to Paying Agents. 

In case 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 in such case (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 Section 16.13 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 

Section 16.15 Certain Conversions Deemed Payment. 
 For the purposes of this Article only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article XV shall not be deemed to constitute a
payment or distribution on account of the principal of or premium or interest on Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash, property or securities (other than
junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section, the term “junior securities” means (a) shares of any stock of any
class of the Company and (b) securities of the Company which are subordinated in right of payment to all Senior Indebtedness 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 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 Indebtedness and the Holders of the Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article XV. 

Section 16.16 Trust Moneys Not Subordinated. 
 Notwithstanding anything contained herein to the contrary, payments from moneys or the proceeds of U.S. Government Obligations held in trust under Article XIV by the Trustee for the payment of
principal of, premium, if any, and interest on the Securities from the date of deposit (if made in compliance with this Indenture) shall not be subordinated to the prior payment of any Senior Indebtedness or subject to the restraints set forth in
this Article, and none of the Securityholders shall be obligated to pay over any such amount to the Company or any holder of Senior Indebtedness of the Company or any other creditor of the Company.
