         Unless this certificate is presented by an authorized representative of
The Depository Trust Company (55 Water Street, New York, New York) (the
"Depositary") to the Company or its agent for registration of transfer, exchange
or payment, and any certificate issued is registered in the name of Cede & Co.
or such other name as requested by an authorized representative of the
Depositary and any payment is made payable to Cede & Co., ANY TRANSFER, PLEDGE
OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since
the registered owner hereof, Cede & Co., has an interest herein.

         Unless and until this Security is exchanged in whole or in part for
certificated Securities registered in the names of the various beneficial
holders hereof as then certified by the Depositary or a successor depositary,
this Security may not be transferred except as a whole by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to another nominee
of the Depositary or to the Depositary or by the Depositary or any such nominee
to a successor Depositary or a nominee of such successor depositary.

     LEGGETT & PLATT, INCORPORATED, a corporation duly organized and existing
under the laws of Missouri (herein called the "Company", which term includes any
successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to CEDE & CO., or registered assigns, the
principal sum of ONE HUNDRED FIFTY MILLION DOLLARS on July 1, 2018, and to pay
interest thereon from June 24, 2003 or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, semiannually in
arrears on January 1 and July 1 in each year, commencing January 1, 2004 at the
rate of 4.40% per annum until the principal hereof is paid or made available for
payment. Interest so payable shall be computed on the basis of a 360-day year
consisting of twelve 30-day months. The interest so payable, and paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, which shall be the December 15 or June 15 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date.
Notwithstanding the foregoing, interest payable at Maturity shall be paid to the
Person to whom principal shall be paid. Any such interest not so paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such Special Record Date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.

     Payment of the principal of and interest on this Security will be made at
the offices of JPMorgan Chase Bank in New York, New York or at such other office
or agency as may be designated for such purpose by the Company from time to time
and will be made in such coin or currency of the United States of America as at
the time of payment is legal tender for the payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register, provided, further, that Holders
of $1,000,000 or more in aggregate principal amount of the Securities of this
series shall be entitled to receive payment of interest by wire transfer to an
account of the Person entitled thereto located in the United States, provided,
that such Person shall have given to the Paying Agent satisfactory wire transfer
instructions by the Regular Record Date preceding the applicable interest
payment date, with reference to the identifying information concerning such
Holder to be found in the Security Register.

         The Securities of this series are subject to redemption prior to Stated
Maturity as described on the reverse hereof.

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by or
on behalf of the Trustee referred to on the reverse hereof by manual signature,
this Security shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.

                              REVERSE SIDE OF NOTE

         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 November 24, 1999 (herein called the
"Indenture"), between the Company and JPMorgan Chase Bank (formerly known as The
Chase Manhattan Bank), 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 and the Holders of the Securities and of the terms upon
which the Securities are, and are to be authenticated and delivered. The
acceptance of this Security shall be deemed to constitute the consent and
agreement by the Holders hereof to all of the terms and provisions of the
Indenture. This Security is one of the series designated on the face hereof. By
the terms of the Indenture, additional Securities of other separate series,
which may vary as to date, amount, Stated Maturity, interest rate or method of
calculating the interest rate and in other respects as therein provided, may be
issued in an unlimited principal amount.

         If any Interest Payment Date, Redemption Date or the Stated Maturity of
this Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of the Indenture or this Security), payment
of interest or principal due on this Security need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at the
Place of Payment, with the same force and effect as if made on the Interest
Payment Date, Redemption Date or at Stated Maturity, provided that no interest
shall accrue on such unpaid interest or principal for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be.

         Except as set forth below, this Security is not redeemable prior to
Stated Maturity and is not entitled to the benefit of a sinking fund or any
analogous provision.

         This Security is redeemable, in whole or in part, at the option of the
Company, at any time at a Redemption Price equal to the greater of (i) 100% of
its principal amount, or (ii) as determined by the Quotation Agent (as defined
below), the sum of the present values of the remaining scheduled payments of
principal and interest thereon (not including any portion of those payments of
interest accrued as of the date of redemption) discounted to the Redemption Date
on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Adjusted Treasury Rate (as defined below) plus 15 basis points,
plus, in each case, accrued interest thereon to the Redemption Date.

         "Adjusted Treasury Rate" means, with respect to any Redemption Date,
the rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for that Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the remaining
term of this Security that would be utilized, at the time of selection and in
accordance with customary financial practice, in

                                       4

<PAGE>

pricing new issues of corporate debt securities of comparable maturity to the
remaining term of this Security.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the Reference Treasury Dealer Quotations for the Redemption
Date, after excluding the highest and lowest Reference Treasury Dealer
Quotations, or (ii) if the Trustee obtains fewer than four Reference Treasury
Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

         "Quotation Agent" means one of the Reference Treasury Dealers appointed
by the Company.

         "Reference Treasury Dealer" means (i) J.P. Morgan Securities Inc. and
Goldman, Sachs & Co. and their successors; provided, however, that if the
foregoing shall cease to be a primary U.S. Government securities dealer in New
York City (a "Primary Treasury Dealer"), the Company shall substitute another
Primary Treasury Dealer; and (ii) any other Primary Treasury Dealers selected by
the Company.

         "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined by
the Trustee, after consultation with the Company, of the bid and asked prices
for the Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Trustee by that Reference Treasury
Dealer at 5:00 p.m., New York City time, on the third Business Day preceding
that Redemption Date.

         Notice of any redemption shall be given by first-class mail, postage
pre-paid, mailed not less than 30 days but not more than 60 days before the
Redemption Date to the Holders of the Securities of this series to be redeemed,
at each Holder's address appearing in the Security Register, but failure to give
such notice in the manner herein provided to the Holder of any Securities of
this series designated for redemption shall not affect the validity of the
proceedings for the redemption of any other such Security or portion thereof.
Any notice that is mailed to the Holders in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives the notice. Notice of redemption having been given as aforesaid, the
Securities of this series so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price. Unless the Company defaults in
payment of the Redemption Price, on and after the Redemption Date, interest will
cease to accrue on the Securities of this series or portions thereof called for
redemption. If less than all of the Securities of this series are to be
redeemed, the Securities of this series to be redeemed shall be selected by the
Trustee by such method as the Trustee shall deem fair and appropriate.

         As permitted by Section 301(12) of the Indenture, as set forth and as
determined in an Officers' Certificate, the terms of the Securities of this
series provide for the modification of a restrictive covenant applicable to the
Securities as follows: the limitation on liens in Section 1003(a)(13) has been
modified so that the restrictions on secured debt set forth in Section 1003(a)
shall not apply to, and there shall be excluded from secured debt in any
computation under Section 1003, debt secured by liens not otherwise excepted by
Section 1003 with respect to an aggregate amount of indebtedness of the Company
(including its Subsidiaries) not in excess

                                       5

<PAGE>

of an amount equal to 15% of Consolidated Assets, rather than an amount of
indebtedness of the Company (including its Subsidiaries) not in excess of an
amount equal to 10% of Consolidated Assets, as set forth in the Indenture.

         If an Event of Default with respect to the Securities of this series
shall occur and be continuing, the principal of the Securities of this series
may (subject to the conditions set forth in the Indenture) be declared due and
payable in the manner and with the effect provided in the Indenture.

         The Indenture contains provisions for defeasance at any time of the
Company's obligations in respect of (i) the entire indebtedness of this Security
or (ii) certain restrictive covenants with respect to this Security, in each
case upon compliance with certain conditions set forth therein.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in aggregate principal amount
of the Securities at the time Outstanding of each series to be affected and, for
certain purposes, without the consent of the Holders of any Securities at the
time Outstanding. The Indenture also contains provisions permitting the Holders
of specified percentages in aggregate principal amount of the Securities of each
series at the time Outstanding, on behalf of the Holders of all Securities of
such series, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
hereof or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and interest
on this Security are payable, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Securities of this series,
of like tenor and of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

                                       6

<PAGE>

         The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any amount in excess thereof
which is an integral multiple of $1,000. As provided in the Indenture and
subject to certain limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series
and of like tenor of a different authorized denomination, as requested by the
Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered in the Security Register as
the owner hereof for all purposes, whether or not this Security be overdue, and
neither the Company, the Trustee nor any such agent shall be affected by notice
to the contrary.

         This Security shall be governed by and construed in accordance with the
laws of the State of New York, without regard for principles of conflicts of
law.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

         As provided in the Indenture, no recourse shall be had for the payment
of the principal of or interest on any Securities, or any part thereof, or for
any claim based thereon or otherwise in respect thereof, or of the indebtedness
represented thereby, or upon any obligation, covenant or agreement under the
Securities or the Indenture, against, and no personal liability whatsoever shall
attach to, or be incurred by, any incorporator, stockholder, officer or
director, as such, past, present or future of the Company or of any predecessor
or successor corporation (either directly or through the Company or a
predecessor or successor corporation), whether by virtue of any constitutional
provision, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly agreed and understood that the
Indenture and all the Securities are solely corporate obligations and that any
such personal liability is hereby expressly waived and released as a condition
of, and as a part of the consideration for, the execution of the Indenture and
the issuance of the Securities.

extent applicable, be governed by such provisions. 
  
 All things

 NOW, THEREFORE, THIS INDENTURE WITNESSETH: 
  
 For and in consideration of the premises and the purchase of the Securities by the Holders thereof, it is mutually covenanted and agreed, for the equal
and proportionate benefit of all Holders of the Securities or of a series thereof, as follows: 
  
 ARTICLE I 
  
 DEFINITIONS AND
OTHER PROVISIONS OF GENERAL APPLICATION 
  
 Section 1.1 Definitions. 
  
 “Act,”
when used with respect to any Holder, has the meaning specified in Section 13.3. 
  
 “Adjusted Consolidated Net Tangible Assets” means (without duplication), as of the date of determination, (a) the sum of (i) discounted future net revenues from proved oil and gas reserves of the Company and
its Restricted Subsidiaries (including, without limitation, oil and gas reserves owned by an oil and gas royalty trust and attributable to the Company or a Restricted Subsidiary by virtue of its ownership of Capital Stock of such royalty trust)
calculated in accordance with SEC guidelines before any state or federal income taxes, as estimated by a nationally recognized firm of independent petroleum engineers in a reserve report prepared as of the end of the Company’s most recently
completed fiscal year, as increased by, as of the date of determination, the estimated discounted future net revenues from (A) estimated proved oil and gas reserves acquired since the date of such year-end reserve report, and (B) estimated oil and
gas reserves attributable to upward revisions of estimates of proved oil and gas reserves since the date of such year-end reserve report due to exploration, development or exploitation activities, in each case calculated in accordance with SEC
guidelines (utilizing the prices utilized in such 

 
year-end reserve report), and decreased by, as of the date of determination, the estimated discounted future net revenues from (C) estimated proved oil and
gas reserves produced or disposed of since the date of such year-end reserve report and (D) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since the date of such year-end reserve report
due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end
reserve report); provided that, in the case of each of the determinations made pursuant to clauses (A) through (D), such increases and decreases shall be as estimated by the Company’s petroleum engineers, (ii) the capitalized costs that
are attributable to oil and gas properties of the Company and its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the
Company’s latest annual or quarterly financial statements, (iii) the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial statements and (iv) the greater of (A) the net book value on
a date no earlier than the date of the Company’s latest annual or quarterly financial statements or (B) the appraised value, as estimated by independent appraisers, of other tangible assets (including, without duplication, investments in
unconsolidated Restricted Subsidiaries) of the Company and its Restricted Subsidiaries, as of the date no earlier than the date of the Company’s latest audited financial statements, minus (b) the sum of (i) minority interests (other than a
minority interest in a Subsidiary that is a business trust or similar entity formed for the primary purpose of issuing preferred securities the proceeds of which are loaned to the Company or a Restricted Subsidiary), (ii) any net gas balancing
liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest audited financial statements, (iii) to the extent included in (a)(i) above, the discounted future net revenues, calculated in accordance with SEC
guidelines (using the prices utilized in the Company’s year-end reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with
respect to Volumetric Production Payments on the schedules specified with respect thereto and (iv) the discounted future net revenues, calculated in accordance with SEC guidelines (using prices utilized in the Company’s year-end reserve
report), attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in (a)(i) above, would be
necessary to fully satisfy the payment obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto. If the Company changes its method of accounting
from the successful efforts method to the full cost method or a similar method of accounting, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Company was still using the successful efforts method of
accounting. 
  
 “Affiliate” means, with respect to any
specified Person, any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For the purposes of this definition, “control,” when used with respect to any

meanings correlative to the foregoing. For purposes of this definition, beneficial ownership of 10% or more of the voting common equity (on a fully 
  

 2

primary term thereof, without giving effect to any renewals at the option of the lessee, discounted from the respective due dates thereof to such date of determination at the rate of interest per annum implicit in the terms of the lease. As used in
the preceding sentence, the “net amount of rent” under any lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by the lessee thereunder, excluding any amounts required
to be paid by such lessee on account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges. In the case of any lease which is terminable by the lessee upon payment of a penalty, such net amount of rent shall also
include the amount of such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated. 
  
 “Average Life” means, with respect to any Indebtedness, as at any date of determination, the quotient obtained by
dividing (a) the sum of the products of (i) the number of years (and any portion thereof) from the date of determination to the date or dates of each successive scheduled principal payment (including any sinking fund or mandatory redemption payment
requirements) of such Indebtedness multiplied by (ii) the amount of each such principal payment by (b) the sum of all such principal payments. 
  
 “Board of Directors” means, with respect to the Company, either the board of directors of the Company or any duly authorized committee of such
board of directors, and, with respect to any Restricted Subsidiary, either the board of directors of such Restricted Subsidiary or any duly authorized committee of that board.

Friday which is not a day on which banking institutions in the Borough of Manhattan, The City of New York, New York, or the city in which the Trustee’s Corporate Trust Office is located, are authorized or obligated by law or executive order to
close. 
  

 3

interest (including of an oil and gas royalty trust), interests, participations, rights in or other equivalents in the equity interests (however designated) in such Person, and any rights (other than debt securities convertible into an equity
interest), warrants or options exercisable for, exchangeable for or convertible into such an equity interest in such Person. 
  
 “Capitalized Lease Obligation” means any obligation to pay rent or other amounts under a lease of (or other agreement conveying the right to
use) any property (whether real, personal or mixed) that is required to be classified and accounted for as a capital lease obligation under GAAP, and, for the purpose of this Indenture, the amount of such obligation at any date shall be the
capitalized amount thereof at such date, determined in accordance with GAAP. 
  
 “Cash Equivalents” means (a) any evidence of Indebtedness with a maturity of 365 days or less issued or directly and fully guaranteed or insured by the United States of America or any agency or

 Section 2.3
Denominations. 
  
 The Securities shall be issuable only
in registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. 
  
 Section 2.4 Execution, Authentication, Delivery and Dating. 
  
 The Securities shall be executed on behalf of the Company by its Chairman, its President or one of its Vice Presidents. The
Company’s corporate seal may be affixed, imprinted or reproduced (which may be in facsimile form) on the Securities. The signature of any of these officers on the Securities may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the Securities. 
  
 Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 
  
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and 

  

 22 

 
deliver such Securities as provided in this Indenture. Prior to authentication and delivery of such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and shall be fully protected in relying upon: 
  
 (i) Board Resolutions of the Company authorizing the terms of issuance of any series of Securities; 
  
 (ii) an executed supplemental Indenture, if any; 

 
 (iii) an Officers’ Certificate in accordance with
Section 13.1 stating that all conditions precedent provided for in this Indenture have been complied with; and 
  
 (iv) an Opinion of Counsel stating: 
  
 (1) that the form of such Securities has been established in conformity with the provisions of this Indenture; 
  
 (2) that the Company has the corporate power to issue such
Securities, and such Securities have been duly authorized, executed and delivered by the Company and, assuming due authentication and delivery by the Trustee, constitute valid and legally binding obligations of the Company enforceable in accordance
with their terms (subject to bankruptcy, reorganization, insolvency and other laws and legal principles affecting creditors’ rights and to general principles of equity), and entitled to the benefits of this Indenture; and 
  
 (3) that the execution and delivery by the Company of such
Securities does not violate any applicable law or legal requirement known to such counsel. 
  
 Each Security shall be dated the date of its authentication. 
  
 The Trustee shall have the right to decline to authenticate and deliver any Security under this Section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee
in good faith shall determine that such action would expose the Trustee to personal liability to existing Holders. 
  
 The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Securities. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as
any Securities Registrar, Paying Agent or agent for service of notices and demands. 
  
 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 duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and 

  

 23 

 
the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 
  
 In case the Company, pursuant to and in compliance with Article VII, shall be
consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its Properties substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such
merger, or into which the Company shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to
Article VII, any of the Securities of any series authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other
Securities of the series executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Securities surrendered for such exchange and of like principal
amount; and the Trustee, upon Company Request of the successor Person, shall authenticate and deliver Securities as specified in such request for the purpose of such exchange. If Securities of any series shall at any time be authenticated and
delivered in any new name of a successor Person pursuant to this Section in exchange or substitution for or upon registration of transfer of any Securities, such successor Person, at the option of the Holders of such series but without expense to
them, shall provide for the exchange of all Securities of the series at the time Outstanding for Securities of the series authenticated and delivered in such new name. 
  
 Section 2.5 Securities Registrar and Paying Agent. 
  
 The Company shall maintain an office or agency designated pursuant to
Section 9.2 where Securities of each series may be presented for registration of transfer or for exchange (the “Securities Registrar”) and where Securities of each series may be presented for payment (the “Paying Agent”). The
Securities Registrar shall keep a register of the Securities of each series (the “Security Register”) and of their transfer and exchange. The Security Register shall be in written form or any other from capable of being converted into
written form within a reasonable period of time. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent. 
  
 The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of
the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 5.6. The Company or any Subsidiary may
act as Paying Agent, Registrar, co-registrar or transfer agent. 
  
 For each series of Securities, the Company initially appoints the Trustee as Securities Registrar and Paying Agent in connection with the Securities of such series. 
  

 24 

 Section 2.6 Paying Agent to Hold Money in Trust. 
  
 Prior to 11:00 A.M., New York City time, on each due date of the principal
of, premium, if any, on and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal, premium and interest when so becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, on or interest on Securities and shall notify the
Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require
a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

  
 Section 2.7 Lists of Security Holders.

  
 The Trustee shall preserve in as current a form as is
reasonably practicable the most recent lists available to it of the names and addresses of Holders of each series of Securities. If the Trustee is not the Securities Registrar, the Company shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date of a Security and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of such
Security. 
  
 Section 2.8 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
conclusively evidenced by their execution of such Securities. 
  
 If temporary Securities of any series are issued, the Company will cause Definitive Securities of such series to be prepared without unreasonable delay. After the preparation of Definitive Securities of such series, the temporary Securities
of such series shall be exchangeable for Definitive Securities of such series upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 9.2, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of Definitive Securities of the same series of
authorized denominations. 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. 
  

 25 

 Section 2.9 Transfer and Exchange. 
  
 (a) Transfer and Exchange of Definitive Securities. When Definitive
Securities of any series are presented to the Securities Registrar with the request: 
  
 (i) to register the transfer of such Definitive Securities, or 
  
 (ii) to exchange such Definitive Securities for an equal principal amount of Definitive Securities of the
same series of other authorized denominations, 
  
 the Securities Registrar shall
register the transfer or make the exchange as requested if its requirements for such transactions are met; provided, however, that the Definitive Securities presented or surrendered for registration of transfer or exchange shall be duly
endorsed or accompanied by a written instrument of transfer in form satisfactory to the Securities Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing. 
  
 (b) Restriction on Transfer of a Definitive Security for a Beneficial
Interest in a Global Security. A Definitive Security of a series may not be exchanged for a beneficial interest in a Global Security of the same series except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of
a Definitive Security of a series, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with written instructions directing the Trustee to make, or directing the Security Custodian to
make, an endorsement on the Global Security of the same series to reflect an increase in the aggregate principal amount of the Securities represented by such Global Security, then the Trustee shall cancel such Definitive Security in accordance with
Section 2.14 and cause, or direct the Security Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Security Custodian, the aggregate principal amount of Securities represented by
such Global Security to be increased accordingly. If no Global Securities of such series are then outstanding, the Company shall issue and the Trustee shall authenticate a new Global Security of the same series in the appropriate principal amount.

  
 (c) Transfer and Exchange of Global Securities. The
Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Security. The transfer and exchange of Global Securities of any series or beneficial interests therein shall be effected through the Depositary,
in accordance with this Indenture and the procedures of the Depositary therefor. 
  
 (d) Transfer of a Beneficial Interest in a Global Security for a Definitive Security. 
  
 (i) Any Person having a beneficial interest in a Global Security of any series may upon request to the Trustee exchange such beneficial
interest for a Definitive Security of the same series. Upon receipt by the Trustee of written instructions, or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any Person having a
beneficial interest in a Global Security of a series. The Trustee or the Security Custodian, at the direction of the Trustee, shall, in accordance with the standing instructions and procedures existing between the Depositary 

  

 26 

 
and the Security Custodian, cause the aggregate principal amount of Global Securities of such series to be reduced accordingly and, following such reduction,
the Company shall execute and the Trustee shall authenticate and deliver to the transferee a Definitive Security of the same series in the appropriate principal amount. 
  
 (ii) Definitive Securities of a series issued in exchange for a beneficial interest in a Global Security of
the same series pursuant to this Section 2.9(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The
Trustee shall deliver such Definitive Securities to the Persons in whose names such Securities are so registered. 
  
 (e) Restrictions on Transfer and Exchange of Global Securities. Notwithstanding any other provisions of this Indenture (other than the provisions
set forth in subsection (f) of this Section 2.9), any Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary
or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Each Security certificate evidencing Global Securities shall bear the paragraph referred to in footnote 1 in the form of Security attached
hereto as Exhibit A. 
  
 (f) Authentication of Definitive
Securities in Absence of Depositary. If at any time: 
  
 (i) the Depositary for Securities of a series notifies the Company that the Depositary is unwilling or unable to continue as Depositary for such Global Securities of such series and a successor Depositary for such
Global Securities is not appointed by the Company within 90 days after delivery of such notice; 
  
 (ii) an Event of Default with respect to Securities of a series then Outstanding has occurred and is continuing and the Security Registrar
has received a request from the Depositary to issue Definitive Securities of such series in lieu of all or a portion of the Global Security (in which case the Company shall deliver such Definitive Securities within 30 days of such request); or

  
 (iii) the Company, at its sole discretion,
notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities of a Series under this Indenture; 
  
 then the Company will execute, and the Trustee will authenticate and deliver, Definitive Securities of such series in an aggregate principal amount equal to the principal
amount of the Global Securities of such series, in exchange for such Global Securities and registered in such names as the Depositary shall instruct the Trustee or the Company in writing. 
  
 (g) Cancellation and/or Adjustment of Global Security. At such time as all beneficial interests in a Global Security
of a series have either been exchanged for Definitive Securities of such series, redeemed, repurchased or canceled, such Global Security shall be returned to or retained and cancelled by the Trustee. At any time prior to such cancellation, if any
beneficial 

  

 27 

 
interest in such Global Security is exchanged for Definitive Securities of such series, redeemed, repurchased or cancelled, the principal amount of
Securities represented by such Global Security shall be reduced and an endorsement shall be made on such Global Security, by the Trustee or the Security Custodian, at the direction of the Trustee to reflect such reduction. 
  
 (h) General Provisions with respect to Transfer and Exchanges.

  
 (i) To permit registrations of transfers and
exchanges, the Company shall execute and the Trustee shall authenticate Definitive Securities and Global Securities at the Registrar’s request. 
  
 (ii) No service charge shall be made to a Holder for any registration of transfer or exchange or redemption of Securities (except as
otherwise expressly permitted herein), but the Company or the Security Registrar may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than such transfer tax or
similar governmental charge payable upon exchanges pursuant to the last paragraph of Section 2.4 or Sections 2.8, 8.6 or 10.7). 
  
 (iii) The Trustee shall authenticate Definitive Securities and Global Securities in accordance with the provisions of Section 2.4.

  
 (iv) Notwithstanding any other provisions of
this Indenture to the contrary, the Company shall not be required to register the transfer or exchange of a Security between the record date and the next succeeding Interest Payment Date. 
  
 (v) Neither the Company nor the Trustee will have any
responsibility or liability for any aspect of the records relating to, or payments made on account of, Securities of any series by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to such
Securities. Neither the Company nor the Trustee shall be liable for any delay by the related Global Security Holder or the Depositary in identifying the beneficial owners of the related Securities, and the Company and the Trustee may conclusively
rely on, and shall be protected in relying on, instructions from such Global Security Holder or the Depositary for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Securities of any
series to be issued). 
  
 (vi) Neither the
Trustee, the Security Registrar nor the Company shall be required (A) to issue, register the transfer of or exchange any Security of a series during a period beginning at the opening of business 15 days before the mailing of a notice of redemption
of Securities of such series selected for redemption under Section 10.3 and ending at the close of business on the day of such mailing of the relevant notice of redemption, or (B) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
  

 28 

 (vii) 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. 
  
 (viii) Each Holder of a Security of a series agrees to
indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable federal or state securities law.

  
 Section 2.10 Additional Provisions for
Global Securities. 
  
 (a) The Global Security of any series
initially shall be registered in the name of the Depositary for such Global Security or the nominee of such Depositary and be delivered to the Trustee as custodian for such Depositary. 
  
 (b) Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture
with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under any Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as
the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee, from giving effect to any written certification,
proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Security. 
  
 (c) The registered holder of the Global Security of any series may grant
proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any permitted by a Holder of Securities of such series. 
  
 Section 2.11 Mutilated, Destroyed, Lost and Stolen
Securities. 
  
 If (i) any mutilated Security is surrendered
to the Trustee or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them
to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon Company Order the Trustee shall authenticate and deliver,
in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of the same series of like tenor and principal amount 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. 
  

 29 

 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 issued pursuant to this Section in lieu of any mutilated,
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 benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
  
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities. 
  
 Section 2.12 Payment of Interest; Interest Rights Preserved. 
  
 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 such Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 9.2. 
  
 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 shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such and (to the extent lawful) interest on such
defaulted interest at the rate prescribed therefor in such Security (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) may be paid by the Company, at its election in each case, as provided in
clause (1) or (2) below: 
  
 (1) The Company may elect to make
payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the
proposed payment, such money when deposited shall 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 

  

 30 

 
proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided for in Section 14.5, 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 given, 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 in any other
lawful manner not inconsistent with the requirements of any securities exchange on which the 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. 
  
 Section 2.13 Persons Deemed Owners. 
  
 Prior to the due presentment of a Security for registration of transfer, the Company, the Securities Registrar, 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 premium, if any, on) and (subject to Section 2.12) interest on such Security and
for all other purposes whatsoever, whether or not such Security be overdue, and none of the Company, the Security Registrar, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 
  
 Section 2.14 Cancellation. 
  
 All Securities surrendered for payment, redemption, registration of transfer
or exchange or for credit against any sinking fund 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 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 delivered to the Company. 
  
 Section 2.15 Computation of Interest. 
  
 Except as otherwise provided or contemplated by Section 2.1, interest on the
Securities of each series shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 
  

 31 

 Section 2.16 CUSIP Numbers. 
  
 The Company in issuing the Securities of any series may use numbers assigned
by the Committee on Uniform Securities Identification Procedures (“CUSIP”) and corresponding International Securities Identification Numbers (“ISIN”) (if then generally in use), and, if so, the Trustee shall use “CUSIP”
numbers and corresponding ISINs (if then generally in use) 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 change in the CUSIP numbers or ISINs. 
  
 Section 2.17 Form of Trustee’s Certificate of Authentication. 
  
 The Trustee’s certificate of authentication shall be in substantially the following form:

 Section 4.2 Acceleration of Maturity; Rescission and Annulment. 
  
 If an Event of Default (other than an Event of Default specified in Section
4.1(i) or (j)) with respect to Securities of any series at the time Outstanding shall occur and be continuing, the Trustee, by written notice to the Company, or the holders of at least 25% in aggregate principal amount of the Outstanding Securities
of that series, by notice to the Trustee and the Company, may declare all unpaid principal of (or, if Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in
the 

  

 36 

 
terms thereof), premium, if any, and accrued interest on all Securities of that series to be due and payable immediately, upon which declaration all amounts
payable in respect of such Securities shall be immediately due and payable. If an Event of Default specified in Section 4.1(i) or (j) occurs and is continuing, then the principal of (or, if 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), premium, if any, and accrued interest on all Outstanding Securities shall ipso facto become and be immediately due and payable
without any declaration, notice or other act on the part of the Trustee or any Holder. 
  
 At any time after a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in
this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind such declaration and its consequences if: 
  
 (a) the Company has paid or deposited with the Trustee a sum sufficient to
pay: 
  
 (i) all sums paid or advanced by the
Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, 
  
 (ii) all overdue interest on all Outstanding Securities of that series, 
  
 (iii) all unpaid principal of (and premium, if any, on) any Outstanding Securities of that series which has
become due otherwise than by such declaration of acceleration and interest on such unpaid principal at the rate borne by such Securities, and 
  
 (iv) to the extent that payment of such interest is lawful, interest upon overdue interest and overdue principal which has become due
otherwise than by such declaration of acceleration (without duplication of any amount deposited pursuant to clauses (ii) and (iii) above), at the rate or rates prescribed therefor in such Securities of that series; 
  
 (b) the rescission would not conflict with any judgment or decree of a court
of competent jurisdiction; and 
  
 (c) all Events of Default with
respect to Securities of that series, other than the nonpayment of principal of (or premium, if any, on), and interest on Securities of that series that has become due solely by such declaration of acceleration, have been cured or waived as provided
in Section 4.13. 
  
 No such rescission shall affect any subsequent default or
impair any right consequent thereon. 
  
 Notwithstanding the
foregoing, in the event of a declaration of acceleration in respect of Securities of a series because of an Event of Default specified in (A) Section 4.1(e) shall have occurred and be continuing, such declaration of acceleration and any
consequential acceleration 

  

 37 

 
shall be automatically rescinded if the Indebtedness that is the subject of such Event of Default has been repaid, or if the default relating to such
Indebtedness is waived or cured and if such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness (provided, in each case, that such repayment, waiver, cure or
rescission is effected within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration), or (B) Section 4.1(f) shall have occurred and be continuing, such declaration and any
consequential acceleration shall be automatically rescinded if the proceedings or enforcement action with respect to the Indebtedness that is the subject of such Event of Default are terminated or rescinded, or such Indebtedness has been repaid and
only so long as the holder of such Indebtedness shall not have applied any Property referenced in such Section 4.1(f) in satisfaction of such Indebtedness; and, in the case of both (A) and (B) above, written notice of such repayment, or cure or
waiver and rescission, as the case may be, shall have been given to the Trustee by the Company and countersigned by the holders of such Indebtedness or a trustee, fiduciary or agent for such holders or other evidence satisfactory to the Trustee of
such events is provided to the Trustee, within 30 days after such declaration of acceleration in respect of such Securities, and no other Event of Default has occurred during such 30-day period which has not been cured or waived during such period,
and so long as such rescission of the declaration of acceleration of such Securities does not conflict with any judgement or decree as certified to the Trustee by the Company. 
  
 Section 4.3 Collection of Indebtedness and Suits for Enforcement by Trustee. 
  
 The Company covenants that if: 
  
 (i) default is made in the payment of any installment of
interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
  
 (ii) 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 the Trustee for the benefit of the
Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall
be legally enforceable, upon any overdue installment of interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
  
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial
proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the 

  

 38 

 
moneys adjudged or decreed to be payable in the manner provided by law out of the Property of the Company or any other obligor upon such Securities, wherever
situated. 
  
 If an Event of Default with respect to Securities of
any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in any provision of such Securities or this Indenture or in aid of the exercise of any power granted therein or herein, or to enforce
any other proper remedy. 
  
 Section 4.4
Trustee May File Proofs of Claim. 
  
 In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the Property of the Company or
of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities of any series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company or such other obligor for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise: 
  
 (i) to file and prove a claim for the whole amount of
principal (and premium, if any) and interest owing and unpaid in respect of such Securities and to file such other papers or documents and take any other actions including participation as a full member of any creditor or other committee as may be
necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and 
  
 (ii) 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 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 the Trustee any amount due to 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 5.6. 
  
 Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

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.

 it being understood and intended that no one or more Holders of Securities of a series 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 Holders of Securities of that series, or to obtain or to seek to obtain priority or preference over any other Holders of Securities of that series or to enforce any
right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders of Securities of that series.

 41 

 Section 4.11 Delay or Omission Not Waiver. 
  
 No delay or omission of the Trustee or of any Holder to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

 (b) The Trustee may resign at any time with respect to Securities of one
or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 5.10 shall not have been delivered to the Trustee within 30 days after the giving of such notice of

 (c) The Trustee may be removed at any time with respect to Securities of any

property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution, shall promptly appoint a successor Trustee with respect to the Securities of such series. If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series and supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to Securities of a series shall have been so appointed by the Company or Holders and accepted appointment in the manner required by Section 5.10, any Holder who has been a bona fide Holder of a Security
for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. Such successorship may, but
need not be, evidenced by a supplemental indenture.

Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective, and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of all amounts due it under Section 5.6, execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Company shall execute any and all instruments to more fully and certainly vest in and confirm to such successor Trustee all such rights, powers and trusts. 
  
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be
qualified and eligible under this Article. 
  
 Section 5.11 Merger, Conversion, Consolidation or Succession to Business. 
  
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party,
or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article,
without the 

  

 48 

 
execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities; and in case at that time any of the Securities shall not have been authenticated, any successor Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the
successor Trustee; and in all such cases such certificates shall have the full force that is provided anywhere in the Securities or in this Indenture; provided, however, that the right to adopt the certificate of authentication of any
predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

 If and when the Trustee shall be or become a creditor of the Company (or any
other obligor under the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company or any such other obligor.

sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of (and premium, if any, on) or interest on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall

taxes, assessments and governmental charges levied or imposed upon the Company or any Restricted Subsidiary or upon the income, profits or Property of the Company or any Restricted Subsidiary and (b) all lawful claims for labor, materials and
supplies, which, if unpaid, might by law become a Lien upon the Property of the Company or any Restricted Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings and for which appropriate provision has been made in accordance with GAAP. 
  

 56 

 Section 9.6 Maintenance of Properties. 
  
 The Company shall cause all material Properties owned by the Company or any
Restricted Subsidiary and used or held for use in the conduct of its business or the business of any Restricted Subsidiary to be maintained and kept in good condition, repair and working order (ordinary wear and tear excepted), all as in the
judgment of the Company may be necessary so that its business may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the maintenance of any of
such Properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Restricted Subsidiary and not disadvantageous in any material respect to the Holders of Securities of any
series. Notwithstanding the foregoing, nothing contained in this Section 9.6 shall limit or impair in any way the right of the Company and its Restricted Subsidiaries to sell, divest and otherwise to engage in transactions that are otherwise
permitted by this Indenture. 
  
 Section 9.7
Insurance. 
  
 The Company shall at all times keep all of
its and its Restricted Subsidiaries’ Properties which are of an insurable nature insured (including appropriate self-insurance) with insurers, believed by the Company to be responsible, against loss or damage to the extent that, in the
reasonable good faith opinion of the Company, property of similar character is usually so insured by corporations similarly situated and owning like properties. 
  

The Company may adopt such other plan or method of protection, in lieu of or supplemental to insurance with insurers, whether by the establishment of
an insurance fund or reserve to be held and applied to make good losses from casualties, or otherwise, conforming to the systems of self-insurance, in the reasonable good faith opinion of the Company, maintained by corporations similarly situated
and owning like properties, as may be determined by the Board of Directors. 
  
 Section 9.8 Statement by Officers as to Default. 
  
 (a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year of the Company and within 45 days of the end of each of the first, second and third quarters of each fiscal year of the
Company, an Officers’ Certificate, one of the signers of which shall be the principal executive officer, principal financial officer or principal accounting officer of the Company, stating that a review of the activities of the Company and its
Subsidiaries during the preceding fiscal quarter or fiscal year, as applicable, has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations
under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of such Officer’s knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this
Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which such Officer
may have knowledge and what action 

  

 57 

 
the Company is taking or proposes to take with respect thereto). Such Officers’ Certificate shall comply with TIA Section 314(a)(4). For purposes of
this Section 9.8(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. 
  
 (b) The Company shall, so long as any Securities of any series are Outstanding, deliver to the Trustee forthwith upon any Officer becoming aware of any
Default or Event of Default or default in the performance of any covenant, agreement or condition contained in this Indenture, an Officers’ Certificate specifying such Default or Event of Default and what action the Company proposes to take
with respect thereto within 10 days of its occurrence. 
  
 Section 9.9 Reports. 
  
 The Company shall file
on a timely basis with the Commission, to the extent such filings are accepted by the Commission and whether or not the Company has a class of securities registered under the Exchange Act, the annual reports, quarterly reports and other documents
that the Company would be required to file if it were subject to Section 13 or 15(d) of the Exchange Act). The Company will also file with the Trustee copies of such reports and documents within 15 days after the date on which the Company files such
reports and documents with the Commission or the date on which the Company would be required to file such reports and documents if the Company were so required. The Company also will furnish at its cost copies of such reports and documents to any
Holder of Securities promptly upon written request, irrespective of whether or not the Company files any such report or document with the Commission. The Company also shall comply with other provisions of TIA Section 314(a). 
  
 Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of
its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
  
 Section 9.10 Limitation on Liens. 
  
 The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume, affirm or suffer to exist or
become effective any Lien of any kind, except for Permitted Liens, on or with respect to any of its property or assets (including any intercompany notes), whether owned at the date of this Indenture or thereafter acquired, or any income, profits or
proceeds therefrom, unless (a) in the case of any Lien securing Subordinated Indebtedness, the Securities (then Outstanding and thereafter created) are secured by a Lien on such property, assets or proceeds that is senior in priority to such Lien
and (b) in the case of any other Lien, the Securities (then Outstanding and thereafter created) are directly secured equally and ratably with the obligation or liability secured by such Lien. 
  

 58 

 Section 9.11 Waiver of Certain Covenants. 
  
 The Company may, with respect to the Securities of any series, omit in any
particular instance to comply with any term, provision or condition set forth in Sections 9.5 through 9.10 if, before or after the time for such compliance, the Holders of at least a majority in principal amount of the Outstanding Securities of each
series affected, by Act of such Holders, waive such compliance in such instance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
  
 Section 9.12 Change of Control. 
  
 (a) Upon the occurrence of a Change of Control, the Company shall be
obligated to make an offer to purchase (a “Change of Control Offer”) all of the then Outstanding Securities of each series, in whole or in part, from the Holders of such Securities in integral multiples of $1,000, at a purchase price (the
“Change of Control Purchase Price”) equal to 101% of the aggregate principal amount of such Securities, plus accrued and unpaid interest to the Change of Control Purchase Date (as defined below), in accordance with the procedures set forth
in paragraphs (b), (c) and (d) of this Section. The Company shall, subject to the provisions described below, be required to purchase all Securities properly tendered into the Change of Control Offer and not withdrawn. The Company will not be
required to make a Change of Control Offer on any series of Securities upon a Change of Control if a third party makes the Change of Control Offer on the Securities of such series at the same purchase price, at the same times and otherwise in
substantial compliance with the requirements applicable to a Change of Control Offer made by the Company and purchases all Securities of such series validly tendered and not withdrawn under such Change of Control Offer. 
  
 (b) The Change of Control Offer is required to remain open for at least 20
Business Days and until the close of business on the fifth Business Day prior to the Change of Control Purchase Date. 
  
 (c) Not later than the 30th day following any Change of Control, the Company shall give to the Trustee in the manner provided in Section 13.4 and each
Holder of Securities in the manner provided in Section 13.5, a notice (the “Change of Control Notice”) stating: 
  
 (1) that a Change in Control has occurred and that such Holder has the right to require the Company to repurchase such Holder’s
Securities, or portion thereof, at the Change of Control Purchase Price; 
  
 (2) any information regarding such Change of Control required to be furnished pursuant to Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder; 
  

 59 

 (3) a purchase date (the “Change of Control Purchase Date”) which shall be on a
Business Day and no earlier than 30 days nor later than 70 days from the date the Change of Control occurred; 
  
 (4) that any Security, or portion thereof, not tendered or accepted for payment will continue to accrue interest; 
  
 (5) that unless the Company defaults in depositing money
with the Paying Agent in accordance with the last paragraph of paragraph (d) of this Section 9.12, or payment is otherwise prevented, any Security, or portion thereof, accepted for payment pursuant to the Change of Control Offer shall cease to
accrue interest after the Change of Control Purchase Date; and 
  
 (6) the instructions a Holder must follow in order to have its Securities repurchased in accordance with paragraph (d) of this Section. 
  
 (d) Holders electing to have Securities purchased will be required to surrender such Securities to the Company at the
address specified in the Change of Control Notice at least five Business Days prior to the Change of Control Purchase Date. Holders will be entitled to withdraw their election if the Company receives, not later than three Business Days prior to the
Change of Control Purchase Date, a facsimile transmission or letter setting forth the name of the Holder, the certificate number(s) and principal amount of Securities delivered for purchase by the Holder as to which his election is to be withdrawn
and a statement that such Holder is withdrawing his election to have such Securities purchased. Holders whose Securities are purchased only in part will be issued new Securities of the same series equal in principal amount to the unpurchased portion
of the Securities surrendered. 
  
 On the Change of Control
Purchase Date, the Company shall (i) accept for payment all Securities or portions thereof tendered pursuant to a Change of Control Offer; (ii) deposit with the Paying Agent money sufficient to pay the purchase price of all Securities or portions
thereof so tendered; and (iii) deliver or cause to be delivered to the Trustee the Securities so accepted. The Paying Agent shall promptly mail or deliver to Holders of Securities so accepted payment in an amount equal to the purchase price, and the
Company shall execute and the Trustee will promptly authenticate and mail or make available for delivery to such Holders a new Security of the same series equal in principal amount to any unpurchased portion of the Security which any Holder did not
surrender for purchase. Any Securities not so accepted will be promptly mailed or delivered to the Holder thereof. The Company shall announce the results of a Change of Control Offer on or as soon as practicable after the Change of Control Purchase
Date. For purposes of this Section 9.12, the Trustee will act as the Paying Agent.

 Section 10.1 Applicability of Article. 
  

Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with the terms of such Securities and,
unless otherwise provided in such terms, this Article. 
  
 Section 10.2 Election to Redeem; Notice to Trustee. 
  
 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), furnish to the Trustee an Officers’ Certificate setting forth such Redemption Date, the Redemption Price and, if less than all the Securities of a series are to be redeemed, the
principal amount of Securities of the series to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 10.3. Any election to redeem
Securities shall be revocable until the Company gives a notice of redemption pursuant to Section 10.4 to the Holders of Securities to be redeemed. 
  
 Section 10.3 Selection by Trustee of Securities to Be Redeemed. 
  
 If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected
not less than 30 days nor more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, pro rata, by lot or by any other method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions of the principal of Securities of such series; provided, however, that any such partial redemption shall be in integral multiples of $1,000. 
  
 The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
  
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities shall relate, in the case
of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed. 
  

 61 

 Section 10.4 Notice of Redemption. 
  
 Notice of redemption shall be given in the manner provided for in Section
13.5 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed. 
  
 All notices of redemption shall identify the Securities to be redeemed (including CUSIP number) and shall state: 
  
 (a) the Redemption Date; 
  
 (b) the Redemption Price; 
  
 (c) if less than all Outstanding Securities of any series are to be redeemed,
the identification (and, in the case of a partial redemption of any series, the principal amounts) of the particular Securities to be redeemed; 
  
 (d) that on the Redemption Date the Redemption Price (together with accrued interest to the Redemption Date payable as provided in Section 10.6) will
become due and payable upon each such Security, or the portion thereof, to be redeemed, and that, unless the Company shall default in the payment of the Redemption Price and any applicable accrued interest, interest thereon will cease to accrue on
and after said date; 
  
 (e) if applicable, that the redemption is
for a sinking fund; and 
  
 (f) the place or places where such
Securities are to be surrendered for payment of the Redemption Price. 
  
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. Notice, if given in the manner
herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect therein to the Holder of any Security of a series shall not affect the
validity of any proceedings for the redemption of other Security of such series. 
  
 Section 10.5 Deposit of Redemption Price. 
  
 On or before 11:00 A.M., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a
Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.3) an amount of money sufficient to pay the Redemption Price of, and accrued and unpaid interest on, all the Securities which
are to be redeemed on such Redemption Date. 
  

 62 

 Section 10.6 Securities Payable on Redemption Date. 
  
 Notice of redemption having been given as aforesaid, the Securities so to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued and unpaid interest to the Redemption Date), and from and after such date (unless the Company shall default in the
payment of the Redemption Price and accrued and unpaid 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 and unpaid interest to the Redemption Date; provided, however, that 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 2.15. 
  
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and
premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Security. 
  
 Section 10.7 Securities Redeemed in Part. 
  
 Any Security which is to be redeemed only in part shall be surrendered at the office or agency of the Company maintained for
such purpose pursuant to Section 9.2 (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 such
Holder’s 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 amount of the Security so surrendered. 
  
 Section 10.8 Optional Redemption at Make-Whole Price.

  
 At any time and from time to time, the Company may, at its
option, redeem all or any portion of any series of Securities at the Make-Whole Price plus accrued and unpaid interest on such Securities so redeemed to the Redemption Date. Any redemption pursuant to this Section 10.8 shall be made, to the extent
applicable, pursuant to the provisions of Sections 10.2 through 10.7. 
  
 Section 10.9 Sinking Fund. 
  
 The terms of the Securities of any series may provide for a sinking fund for the retirement of Securities of that series. The following provisions shall apply to any such sinking fund except as otherwise specified for the Securities of such
series. 
  
 (a) The minimum amount of any sinking fund payment
provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any 

  

 63 

 
payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund
payment.” 
  
 (b) In lieu of making all or any part of any
mandatory sinking fund payment in cash with respect to any Securities of a series, the Company may at its option satisfy all or part of its sinking fund payment obligation with respect to such Securities by (i) delivery of Outstanding Securities of
that series theretofore purchased or otherwise acquired by the Company (other than any Securities previously called for redemption) or (ii) applying as a credit the principal amount of Securities of that series which have been redeemed either at the
election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities; 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 mandatory sinking fund payment
shall be reduced accordingly. 
  
 (c) 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 10.8(b) (including therewith
delivery to the Trustee of any Securities to be so delivered), and whether the Company intends to make any permitted optional sinking fund payment with respect to such series. Not less than 45 days prior to 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 10.3, and the Company shall cause notice of the redemption thereof to be given at its expense in the manner provided in Section
10.4 except that the notice of redemption shall also state that the Securities are being redeemed by operation of the sinking fund. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 10.6 and 10.7. 
  
 ARTICLE XI 
  
 DEFEASANCE AND COVENANT DEFEASANCE 
  
 Section 11.1 Company’s Option to Effect Defeasance
or Covenant Defeasance. 
  
 Unless pursuant to Section 2.1
provision is made that this Article shall not be applicable to the Securities of any series, the Company may, at its option by Board Resolution, at any time, with respect to the Outstanding Securities of any series designated in accordance with
Section 2.1 as being defeasible pursuant to this Article XI, elect to have either Section 11.2 or Section 11.3 be applied to all Outstanding Securities of such series upon compliance with the conditions set forth below in this Article XI.

  

 64 

 Section 11.2 Defeasance and Discharge. 
  
 Upon the Company’s exercise under Section 11.1 of the option applicable
to this Section 11.2, the Company shall be deemed to have been discharged from its obligations with respect to all Outstanding Securities of the applicable series on the date the conditions set forth in Section 11.4 are satisfied (hereinafter
referred to as “legal defeasance”). For this purpose, such legal defeasance means that the Company shall be deemed (a) to have paid and discharged their respective obligations under the Outstanding Securities of such series; provided,
however that the Securities shall continue to be deemed to be “Outstanding” for purposes of Section 11.5 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and (b) to have satisfied all their other
obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive
until otherwise terminated or discharged hereunder: (i) the rights of Holders of Outstanding Securities of such series to receive, solely from the trust fund described in Section 11.4 and as more fully set forth in such Section, payments in respect
of the principal of (and premium, if any, on) and interest on such Securities when such payments are due (or at such time as the Securities would be subject to redemption at the option of the Company in accordance with this Indenture), (ii) the
respective obligations of the Company under Sections 2.4, 2.5, 2.7, 2.8, 2.9, 2.10, 2.11, 4.8, 4.14, 5.6, 5.9, 5.10, 9.1, 9.2 and 9.3, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) the obligations of the
Company under this Article XI. Subject to compliance with this Article XI, the Company may exercise its option under Section 11.1 applicable to this Section 11.2 notwithstanding the prior exercise of its option under Section 11.1 applicable to
Section 11.3. 
  
 Section 11.3 Covenant
Defeasance. 
  
 Upon the Company’s exercise under
Section 11.1 of the option applicable to this Section 11.3, the Company shall be released from its obligations under any covenant contained in Article VII and in Sections 9.5 through 9.10 (and any other covenant, as may be determined pursuant to
Section 2.1, of the applicable series of Securities subject to this provision) with respect to the Outstanding Securities of the applicable series on and after the date the conditions set forth below are satisfied (hereinafter referred to as
“covenant defeasance”), and the Securities of such series shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Outstanding Securities, the Company may
omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any
reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Sections 4.1(c) or 4.1(d) or any additional Event of Default included in
the Securities of such series, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. 

  

 65 

 Section 11.4 Conditions to Defeasance or Covenant Defeasance. 
  
 The following shall be the conditions to application of either Section 11.2
or Section 11.3 to the Outstanding Securities of any series: 
  
 (a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 5.7 who shall agree to comply with the provisions of this Article XI 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 such Securities of such series, (i) cash in U.S. Dollars in an amount, or (ii) U.S.
Government Obligations which 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 (iii) a
combination thereof, 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 other qualifying trustee) to pay and discharge, the principal of (and premium, if any, on) and interest on the Outstanding Securities of such series on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if
any) or installment of interest; provided that the Trustee shall have been irrevocably instructed in writing by the Company to apply such money or the proceeds of such U.S. Government Obligations to said payments with respect to the
Securities of such series. Before such a deposit, the Company may give to the Trustee, in accordance with Section 10.2, a notice of its election to redeem all of the Outstanding Securities of such series at a future date in accordance with Article
X, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing. For this purpose, “U.S. Government Obligations” means securities that are (x) direct obligations of the
United States of America for the timely payment of which its full faith and credit is pledged or (y) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the timely payment of
which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also include a depository receipt issued
by a bank (as defined in Section 3(a)(2) of the Securities Act), as custodian with respect to any such U.S. Government Obligation or a specific payment of principal of or interest on any such U.S. Government Obligation held by such custodian for the
account of the holder of such depository receipt, 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 depository receipt from any amount received by
the custodian in respect of the U.S. Government Obligation or the specific payment of principal of or interest on the U.S. Government Obligation evidenced by such depository receipt. 
  
 (b) No Default or Event of Default with respect to the Securities of such series shall have occurred and be continuing on
the date of such deposit. 
  
 (c) Such legal defeasance or
covenant defeasance shall not cause the Trustee to have a conflicting interest under this Indenture or the Trust Indenture Act with respect to any securities of the Company. 
  

 66 

 (d) Such legal defeasance or covenant defeasance shall not result in a breach or violation of, or
constitute a default under any other material agreement or instrument to which the Company is a party or by which it is bound, as evidenced to the Trustee in an Officers’ Certificate delivered to the Trustee concurrently with such deposit.

  
 (e) In the case of an election under Section 11.2, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the
applicable federal income tax laws; in either case providing that the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such legal defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred (it being understood that (x) such Opinion of Counsel shall also state that such ruling
or applicable law is consistent with the conclusions reached in such Opinion of Counsel and (y) the Trustee shall be under no obligation to investigate the basis of correctness of such ruling). 
  
 (f) In the case of an election under Section 11.3, the Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 
  
 (g) The Company shall have delivered to the Trustee an Officers’ 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 legal defeasance or covenant defeasance. 
  
 (h) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent
provided for relating to either the legal defeasance under Section 11.2 or the covenant defeasance under Section 11.3 (as the case may be) have been complied with. 
  
 Section 11.5 Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous
Provisions. 
  
 Subject to the provisions of the last paragraph
of Section 9.3, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 11.5, the “Trustee”) pursuant to Section 11.4 in
respect of the Outstanding Securities of any series shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including
the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, but such money need not be segregated
from other funds except to the extent required by law. 
  

 67 

 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 11.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding
Securities. 
  
 Anything in this Article XI 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 11.4 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent legal defeasance or covenant defeasance,
as applicable, in accordance with this Article. 
  
 Section 11.6 Reinstatement. 
  
 If the Trustee or
any Paying Agent is unable to apply any money in accordance with Section 11.5 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 the applicable series shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.2 or 11.3, as the case may be, until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 11.5; provided, however, that if the Company makes any payment of principal of (or premium, if any, on) or interest on any Security of a series following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. 
  
 ARTICLE XII 
  
 CONVERSION 
  
 Section 12.1 Applicability; Conversion Privilege and Conversion Price. 
  
 If Securities of any series are designated pursuant to Section 2.2 as
convertible into Common Stock of the Company, such conversion shall be in accordance with the terms of this Article, unless otherwise specified in the terms of such Securities. Conversion provisions for Securities of any series denominated in a
foreign currency or for conversion into a security other than Common Stock of the Company shall be specified in the terms of such Securities in accordance with Section 2.2. Reference in this Article to “Common Stock” shall mean the common
stock, par value $0.01 per share, of the Company authorized on the date of this Indenture and any other class of stock resulting from successive changes or reclassifications of such common stock. 
  
 Subject to and upon compliance with the provisions of this Article, at the
option of the Holder thereof, any Security of a series to which this Article applies, or any portion of the principal amount thereof which equals $1,000 or an integral multiple thereof, may be converted 
  

 68 

 at the principal amount thereof, or of such portion thereof, into fully paid and non-assessable shares (calculated as to
each conversion to the nearest 1/100th of a share) of Common Stock, at the conversion price 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, such conversion right in respect of the Security or portion so called shall expire at the close of business on the Business Day immediately preceding 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 (the “conversion price”) shall be the price specified for the Securities of such series, subject to adjustment as provided in this Article. 
  
 Section 12.2 Conversion Procedure. 
  
 In order to exercise the conversion privilege, the Holder of any Security to
be converted shall surrender to the Company such Security, duly endorsed or assigned to the Company or in blank, at any office or agency of the Company maintained pursuant to Section 9.2, accompanied by written notice of conversion in substantially
the form set forth in the Security (except in the case of a depositary of a Global Security, for which the customary procedures of the depositary will apply). 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 New York Clearing House funds or other 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. Except as provided in the immediately preceding sentence, 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 and after 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 any payment in lieu of any fraction of
a share, as provided in Section 12.3. 
  
 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 the applicable series of
authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Security. 
  

 69 

 Section 12.3 Fractions of Shares. 
  
 No fractional shares of Common Stock or scrip representing fractions of
shares shall be issued upon conversion of Securities. If more than one Security of a series 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) of that series 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 to the Holder of such Security an amount in cash (computed to the nearest cent) based upon the closing price of the Common Stock on the Business Day immediately preceding
the date of conversion. 
  
 Section 12.4
Adjustment of Conversion Price. 
  
 The conversion price
shall be subject to adjustment from time to time as follows: 
  
 (a) In case the Company shall pay or make a dividend or other distribution on any class of its capital stock in shares of its Common Stock, then the conversion price in effect at the opening of business on the day following the record date
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 issued and outstanding
at the close of business on such record date 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 shall become effective immediately after the
opening of business on the day following such record date. 
  
 (b)
In case the Company shall issue rights, options or warrants to all holders of its outstanding shares of 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
of the Common Stock on the record date for determination of stockholders entitled to receive such rights, options or warrants, then the conversion price in effect at the opening of business on the day following such record date 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 such record date 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 such record date plus the number of shares of Common Stock so offered for subscription or purchase. Such reduction shall become effective immediately after the opening of business on the day following such record date. Notwithstanding the
foregoing, in case the Company shall issue rights, options or warrants (“Stockholder Rights”) to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of Common Stock, which rights or warrants
(i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and (iii) are also issued in respect of future issuances of Common Stock, in each case until the occurrence of a specified event or events, such Stockholder
Rights shall for purposes of this Section 12.4 not be deemed issued or distributed until the occurrence of the earliest of such specified events and the 
  

 70 

 conversion price shall not be reduced until the occurrence of such earliest specified event. If the conversion price is
reduced pursuant to this paragraph (b) as a result of any rights, warrants or options that are issued by the Company and if at the end of the period during which such warrants, options, or rights are exercisable, not all such warrants, options or
rights shall have been exercised, the conversion price shall be immediately readjusted to what it would have been had the above fraction been computed based on the number of shares of Common Stock actually issued in respect of such warrants, options
or rights, as the case may be. 
  
 (c) In case outstanding shares
of Common Stock shall be subdivided into a greater number of shares of Common Stock, then 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 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 day upon which such subdivision becomes effective before giving effect to
such subdivision and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the day such subdivision becomes effective after giving effect to such subdivision. Conversely, in case outstanding shares of
Common Stock shall be combined into a smaller number of shares of Common Stock, then 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 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 day upon which such combination becomes effective before giving effect to
such combination and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the day such combination becomes effective after giving effect to such combination. Such reduction or increase, as the case
may be, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
  
 (d) 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 (i) an issuance, dividend or distribution referred to in paragraphs (a) and (b) of this Section paid exclusively in cash or upon the dissolution, liquidation or winding up of the Company or
(ii) Stockholder Rights), then 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 record date for determination of
stockholders entitled to receive such distribution by a fraction of which the numerator shall be the current market price per share of the Common Stock on such record date minus the then fair market value (as determined by the Board of Directors of
the Company, whose determination shall be conclusive and described in a Board Resolution) of the portion of the evidences of indebtedness or assets so distributed applicable to one share of Common Stock and the denominator shall be such current
market price per share of the Common Stock on such record date. Such adjustment shall become effective immediately prior to the opening of business on the day following such record date. 
  
 (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any
cash that is distributed as part of a distribution referred to in paragraph (d) of this Section) in an aggregate amount that, together with (i) the aggregate amount 
  

 71 

 of any other distributions to all holders of its Common Stock made exclusively in cash within the l2 months preceding the
date of payment of such distribution and in respect of which no conversion price adjustment pursuant to paragraph (e) of this Section has been made and (ii) the aggregate of any cash exceeds 10% of the product of the current market price per share
of the Common Stock on the date fixed for the determination of stockholders entitled to receive such distribution multiplied by the number of shares of Common Stock outstanding on such date, then the conversion price shall be reduced so that the
same shall equal the price determined by multiplying the conversion price in effect immediately prior to the effectiveness of the conversion price reduction contemplated by this paragraph (e) by a fraction of which the numerator shall be the current
market price per share of the Common Stock on such date minus the amount of cash so distributed applicable to one share of Common Stock and the denominator shall be such current market price per share of the Common Stock. Such reduction shall become
effective immediately prior to the opening of business on the date following the date fixed for the payment of such distribution. 
  
 (f) The reclassification of Common Stock into securities other than Common Stock (excluding any reclassification upon a merger or consolidation to which
Section 12.12 applies) shall be deemed to involve 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 record date for determination
of stockholders entitled to receive such distribution” within the meaning of paragraph (d) of this Section). If such reclassification changes the number of outstanding shares of Common Stock, then such reclassification shall be deemed (in
addition to any effect provided in the previous sentence) 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, within the meaning of paragraph (c) of this Section). 
  
 (g) No adjustment in the conversion price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided that any adjustment which by reason of this paragraph (g) 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 1/100th of a share, as the case may be. No adjustment in the conversion
price shall be required for any increase or decrease in the par value of the Common Stock. 
  
 (h) In addition to the adjustments in conversion price required by paragraphs (a), (b), (c), (d), (e) and (f) of this Section, the Company may from time to time in its discretion make such decreases in the conversion
price as it considers to be advisable, including for purposes of avoiding or diminishing any Federal 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 Federal income tax purposes or for any other reason. 
  

 72 

 (i) Notwithstanding any other provision of this Article XIII, no adjustment to the conversion price shall
result in zero or in a negative number or shall reduce the conversion price below the then par value per share of the Common Stock, and any such purported adjustment shall instead reduce the conversion price to such par value, unless the Common
Stock then has no par value, in which case such purported adjustment shall instead reduce the conversion price to $.01 per share. The Company hereby covenants not to take any action to increase the par value per share of the Common Stock.

  
 (j) For the purpose of any computation in this Article, the
current market price per share of Common Stock on any date shall be deemed to be the average of the closing prices for the 5 consecutive days (on which securities exchanges are open for trading) preceding such date of determination. The closing
price for each day shall be the last reported sales price regular way or, if no such reported sale takes place on such day, the average of the reported closing bid and asked prices regular way, in either case as reported for consolidated
transactions on the New York Stock Exchange or, if the Common Stock is not listed or admitted to trading on the New York Stock Exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading or, if
the Common Stock is not so listed or admitted to trading, on the Nasdaq Stock Market or, if the Common Stock is not so listed or admitted to trading, the average of the closing bid and asked prices (or if closing bid and asked prices or not
available, the average of the high bid and low asked prices for such day) in the over-the-counter market as published by the appropriate regulatory organization or if not so published as furnished by any New York Stock Exchange member firm selected
from time to time by the Company. 
  
 Section
12.5 Notice of Adjustments of Conversion Price. 
  
 Whenever the conversion price is adjusted as herein provided, the Company shall promptly: 
  
 (i) compute the adjusted conversion price in accordance with Section 12.4 and prepare a certificate signed by the chief financial officer
or 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 file such certificate (with a copy to the Trustee) at each office or agency maintained
for the purpose of conversion of Securities pursuant to Section 9.2; and 
  
 (ii) prepare a notice stating that the conversion price has been adjusted and setting forth the adjusted conversion price, and as soon as practicable thereafter mail such notice to Holders of Securities providing the
conversion right contained in this Article XII at their last addresses as they shall appear in the Securities Register. 
  
 Section 12.6 Trustee’s Adjustment Disclaimer. 
  
 The Trustee has no duty to determine when an adjustment under this Article XII should be made, how it should be made or what
it should be. The Trustee shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon 
  

 73 

 conversion of any Securities. The Trustee shall not be responsible for the Company’s failure to comply with this
Article XII. 
  
 Section 12.7 Notice of
Certain Corporate Actions. 
  
 In case the Company shall
authorize: 
  
 (i) any event which could result
in an adjustment in the conversion price under Section 12.4 or require the execution of a supplemental indenture under Section 12.12; or 
  
 (ii) the granting to holders of its Common Stock generally of rights, options or warrants to subscribe for or purchase any shares of
Capital Stock excluding Stockholder Rights); or 
  
 (iii) any reclassification of the Common Stock, or any merger, consolidation 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 the
properties and assets of the Company substantially as an entirety; or 
  
 (iv) 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 pursuant to Section 9.2, and shall cause to be mailed to all Holders of Securities providing
the conversion right contained in this Article XII at their last addresses as they shall appear in the Security Register, at least 15 days prior to the applicable record, effective or expiration date hereinafter specified, a notice stating (A) the
date on which a record is to be taken for the purpose of such dividend, distribution or granting of rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record who will be entitled to
such dividend, distribution, rights or warrants are to be determined, or (B) the date on which such reclassification, merger, consolidation, 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, merger, consolidation, share
exchange, sale, transfer, dissolution, liquidation or winding up. Neither the failure to give any such notice nor any defect therein shall affect the legality or validity of any action described in this Article XII. In case of the occurrence of any
event triggering the exercisability of Stockholder Rights, then the Company shall cause to be filed at each office or agency maintained pursuant to Section 9.2, and shall cause to be mailed to the Holders of Securities providing the conversion right
contained in this Article XII at their last addresses as they shall appear in the Security Register within 10 days after the occurrence of such event a notice of such event and the date of its occurrence. 
  

 74 

 Section 12.8 Company to Reserve Common Stock. 
  
 The Company shall at all times reserve and keep available, free from
preemptive rights, out of the authorized but unissued Common Stock or out of the Common Stock held in treasury, 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 so convertible. 
  
 Section 12.9 Taxes on Conversions. 
  
 The
Company will pay any and all documentary, stamp or similar issue or transfer 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 12.10 Covenant as to Common Stock.

  
 The Company covenants that all shares of Common Stock issued
upon conversion of Securities will be validly issued, fully paid and non assessable. 
  
 Section 12.11 Cancellation of Converted Securities. 
  
 All Securities delivered for conversion shall be delivered to the Trustee to be cancelled by or at the direction of the
Trustee, which shall dispose of the same as provided in Section 2.14. 
  
 Section 12.12 Effect of Merger, Consolidation or Sale of Assets. 
  
 In case of any merger of the Company into or consolidation of the Company with 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) or any sale or transfer of the properties and assets of the Company substantially as an entirety, the Person
resulting from such merger or consolidation or which acquires such properties and assets of the Company, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then
outstanding shall have the right thereafter, during the period such Security shall be convertible as specified in Section 12.1, to convert such Security only into the kind and amount of securities, cash and other property, if any, receivable upon
such merger, consolidation, sale or transfer by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such merger, consolidation, sale or transfer, assuming such holder of Common
Stock (i) is not a Person into which the Company merged or which merged into the Company or with which the Company consolidated or to which such sale or transfer was made, as the case may be (a “Constituent Person”), or an Affiliate of a
Constituent Person, and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash or 
  

 75 

 other property receivable upon such merger, consolidation, sale or transfer (provided that if the kind or amount of
securities, cash and other property receivable upon such merger, consolidation, sale or transfer is not the same for each share of Common Stock held immediately prior to such merger, consolidation, sale or transfer by other than a Constituent Person
or an Affiliate thereof and in respect of which such rights of election shall not have been exercised (“nonelecting share”), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon
such merger, consolidation, sale or transfer by each nonelecting share shall be deemed to be the kind and amount so receivable per share by a plurality of the nonelecting 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 any successive
merger, consolidation, sale or transfer. No adjustment in the conversion price shall be made pursuant to Section 12.4 as a result of any merger, consolidation, sale or transfer of the properties and assets of the Company substantially as an entirety
to which this Section 12.12 applies. 
  
 ARTICLE XIII 

 
 MISCELLANEOUS 
  
 Section 13.1 Compliance Certificates and Opinions.

  
 Upon any application or request by the Company to the Trustee
to take any action under any provision of this Indenture, the Company shall furnish to the Trustee such certificates and opinions as may be required under the Trust Indenture Act or this Indenture. Each such certificate and each such opinion shall
be in the form of an Officers’ Certificate or an Opinion of Counsel, as applicable, and shall comply with the requirements of this Indenture. 
  
 Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include: 
  
 (i) a statement that each individual signing such
certificate or opinion has read such covenant or condition and the definitions herein relating thereto; 
  
 (ii) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in
such certificate or opinion are based; 
  
 (iii)
a statement that, in the opinion of each such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and

  
 (iv) a statement as to whether, in the
opinion of each such individual, such condition or covenant has been complied with. 
  

 76 

 The certificates and opinions provided pursuant to this Section 13.1 and the statements required by this
Section 13.1 shall comply in all respects with TIA Sections 314(c) and (e). 
  
 Section 13.2 Form of Documents Delivered to Trustee. 
  
 In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one
such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or
give an opinion as to such matters in one or several documents. 
  
 Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such Opinion of Counsel may be based, insofar as it relates to factual matters, upon an
Officers’ Certificate of an Officer or Officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know,
that the certificate with respect to such matters is erroneous. 
  
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one
instrument. 
  
 Section 13.3 Acts of
Holders. 
  
 (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents
duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
  
 (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing
acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The fact 
  

 77 

 and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also
be proved in any other manner which the Trustee deems sufficient. 
  
 (c) The ownership, principal amount and serial numbers of Securities of any series held by any Person, and the date of holding the same, shall be proved by the Security Register. 
  
 (d) If the Company shall solicit from Holders of Securities of any series any request, demand, authorization, direction,
notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than
the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities of a series have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities of a series shall be
computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later
than eleven months after the record date. 
  
 (e) Any request,
demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
  
 Section 13.4 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: 
  
 (i) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in
writing and delivered in person or mailed by certified or registered mail (return receipt requested) to the Trustee at its Corporate Trust Office; or 
  
 (ii) 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 delivered in person or mailed by certified or registered mail (return receipt requested) to the Company addressed to it at the Company’s principal office located at 810 Houston 
  

 78 

 Street, Fort Worth, Texas 76102, or at any other address otherwise furnished in writing to the Trustee by
the Company. 
  
 Section 13.5 Notice to
Holders; Waiver. 
  
 Where this Indenture provides for notice
of any event to Holders by the Company or the Trustee, 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, and not earlier than the earliest date, 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. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such notice. 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 or irregularities in
regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder. 
  
 Section 13.6 Effect of Headings and Table of Contents. 
  
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the
construction hereof. 
  
 Section 13.7
Successors and Assigns. 
  
 All covenants and agreements
in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. All agreements of the Trustee in this Indenture shall bind its successor. 
  
 Section 13.8 Separability Clause. 
  
 In case any provision in this Indenture or in the Securities of any series shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby, and a Holder shall have no claim therefore against any party hereto.

 Section 13.9 Benefits of Indenture. 
  
 Nothing in this Indenture or in the Securities of any series, express or
implied, shall give to any Person (other than the parties hereto, any Paying Agent, any Securities Registrar and their successors hereunder and the Holders) any benefit or any legal or equitable right, remedy or claim under this Indenture.

  
 Section 13.10 Governing Law; Trust
Indenture Act Controls. 
  
 (a) THIS INDENTURE AND
THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THE TRUST INDENTURE ACT IS APPLICABLE. THE COMPANY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES
FEDERAL OR NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE SECURITIES, AND THE COMPANY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF
SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED BY ANY SUCH COURT. 
  
 (b) This Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions. If and to the extent that
any provision of this Indenture limits, qualifies or conflicts with the duties imposed by Sections 310 to 317, inclusive, of the Trust Indenture Act, or conflicts with any provision (an “incorporated provision”) required by or deemed to be
included in this Indenture by operation of Section 318(c) of the Trust Indenture Act, such imposed duties or incorporated provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that
may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or excluded, as the case may be. 
  
 Section 13.11 Legal Holidays. 
  
 In any case where any Interest Payment Date, Redemption Date, or Stated Maturity or Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities of any series) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date, Redemption Date or at the Stated Maturity or Maturity; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or
Maturity, as the case may be. 
  
 Section 13.12
No Recourse Against Others. 
  
 A director, officer,
employee or stockholder of the Company shall not have any liability, by reason of his or its status as such director, officer, employee or stockholder, for any 
  

 80 

 obligations of the Company under the Securities of any series or this Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. Each Holder, by accepting any Security, waives and releases all such liability to the extent permitted by applicable law. 
  
 Section 13.13 Duplicate Originals. 
  
 The parties may sign any number of copies or counterparts of this Indenture. Each signed copy shall be an original, but all
of them together represent the same agreement. 
  
 Section 13.14 No Adverse Interpretation of Other Agreements. 
  
 This Indenture may not be used to interpret another indenture, loan or debt agreement of the Company or any of its Subsidiaries. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

  
 IN WITNESS WHEREOF, the parties hereto have caused this
Indenture to be duly executed as of the day and year first above written.

 XTO Energy Inc., a Delaware corporation (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter

to pay interest thereon, commencing on                          and continuing semiannually thereafter, on
                     and
                     of each year, from
                    , or from the most recent Interest Payment Date to which interest has been paid or duly provided for, at the rate of
        % per annum, until the principal hereof is paid or duly provided for [if applicable, insert:            , and (to the extent lawful)
to pay on demand, interest on any overdue interest at [        %] or [the rate borne by the Securities] from the date on which such overdue interest becomes payable to the date payment of such interest
has been made or duly provided for]. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the                  or
                 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly
provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record
Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest on the
Securities of this series shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 
  
 Payment of the principal of, premium, if any, and interest on this Security will be made at the office or agency of the Company maintained for that
purpose in the City of New York, or at such other office or agency of the Company as may be maintained for such purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and
private debts; provided however, that payment of interest may be made at the option of the Company (i) by check mailed to Holders at their respective addresses as shown in the Security Register or (ii) with respect to any Holder owning
Securities in the principal amount of $500,000 or more, by wire transfer to an account maintained by the Holder located in the United States, as specified in a written notice to the Trustee (received prior to the relevant record date) by any such

 [Form of Reverse] 
  
 This Security is one of a duly authorized issue of the series of securities of the Company designated as its [name of
designated series] (herein called the “Securities”), which is issued under, with securities of one or more additional series that may be issued under, an indenture (herein called the “Indenture”) dated as of
                    , 2003 between the Company and
                                        ,
as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all applicable indentures supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. 
  
 [If applicable, insert: The Securities are subject to redemption at the
option of the Company, in whole or in part, at any time and from time to time, upon not less than 30 or more than 60 days’ notice, at a Redemption Price of 100% of their principal amount plus a Make-Whole Amount, together in the case of any
such redemption with accrued and unpaid interest to the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date),
all as provided in the Indenture. 
  
 [In the case of any
redemption of Securities, interest installments whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant
Record Date referred to on the face hereof. Securities (or portions thereof) for whose redemption and payment provision is made in accordance with the Indenture shall cease to bear interest from and after the Redemption Date.] 
  
 [If applicable, insert: At the option of the Holder and subject to the terms
and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of Securities held
by such Holder on a Business Day selected by the Company no earlier than 30 days nor later than 70 days after the occurrence of a Change of Control, at a purchase price equal to 101% of the principal amount thereof together with accrued and unpaid
interest to the Change of Control Purchase Date. The Holder shall have the right to withdraw any Change of Control Purchase election (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time
prior to the close of business on the third Business Day next preceding the Change of Control Purchase Date by delivering a written notice of withdrawal to the Company in accordance with the terms of the Indenture.] 
  
 [In the event of redemption or purchase of this Security in part only, a new
Security or Securities for the unredeemed or unpurchased portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.] 
  
 [If applicable insert: The Securities do not have the benefit of any sinking fund obligations.] 
  

 A-4 

 As set forth in the Indenture, an Event of Default is generally (a) failure to pay principal upon
maturity, redemption or otherwise; (b) default for 30 days in payment of interest on any of the Securities; (c) default in the performance of agreements relating to mergers, consolidations and sales of all or substantially all assets or to make and
consummate a Change of Control Offer; (d) failure for 30 days after notice to comply with any other covenants in the Indenture or the Securities; (e) certain payment defaults under, the acceleration prior to the maturity of, and the exercise of
certain enforcement rights with respect to, certain Indebtedness of the Company or any Restricted Subsidiary in an aggregate principal amount in excess of $10,000,000; (f) certain events giving rise to ERISA liability; (g) certain final judgments
against the Company or any Restricted Subsidiary in an aggregate amount of $10,000,000 or more which remain unsatisfied and either become subject to commencement or enforcement proceedings or remain unstayed for a period of 60 days; and (h) certain
events of bankruptcy, insolvency or reorganization of the Company or any Restricted Subsidiary. [If applicable, insert additional events of default.] If any Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in
aggregate principal amount of the Outstanding Securities may declare the principal amount of all the Securities to be due and payable immediately, except that (i) in the case of an Event of Default arising from certain events of bankruptcy,
insolvency or reorganization of the Company or any Restricted Subsidiary, the principal amount of the Securities will become due and payable immediately without further action or notice and (ii) in the case of an Event of Default which relates to
certain payment defaults, acceleration or the exercise of certain enforcement rights with respect to certain Indebtedness, any acceleration of the Securities will be automatically rescinded if any such Indebtedness is repaid or if the default
relating to such Indebtedness is cured or waived and if the holders thereof have accelerated such Indebtedness then such holders have rescinded their declaration of acceleration or if in certain circumstances the proceedings or enforcement action
with respect to the Indebtedness that is the subject of such Event of Default is terminated or rescinded. No Holder may pursue any remedy under the Indenture unless the Trustee shall have failed to act after notice of an Event of Default and written
request by Holders of at least 25% in principal amount of the Outstanding Securities, and the offer to the Trustee of indemnity reasonably satisfactory to it; however, such provision does not affect the right to sue for enforcement of any overdue
payment on a Security by the Holder thereof. Subject to certain limitations, Holders of a majority in principal amount of the Outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders
notice of any continuing default (except default in payment of principal, premium or interest) if it determines in good faith that withholding the notice is in the interest of the Holders. The Company is required to file quarterly reports with the
Trustee as to the absence or existence of defaults. 
  
 [If
applicable insert: The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of the Company on this Security and (ii) certain restrictive covenants and the related Defaults and Events of Default, upon compliance by
the Company with certain conditions set forth therein, which provisions apply to this Security.] 
  
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders under the Indenture at any time by the Company and the Trustee with the consent of the 
  

 A-5 

 Holders of a majority in aggregate principal amount of the Securities at the time Outstanding. The Indenture also
contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions
of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by or on behalf of the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security. Without the consent of any Holder, the Company and
the Trustee may amend or supplement the Indenture or the Securities to cure any ambiguity, defect or inconsistency, to provide for uncertificated Securities in addition to or in place of Definitive Securities and to make certain other specified
changes and other changes that do not adversely affect the rights of any Holder. 
  
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and
premium, if any, on) and interest on this Security at the times, place, and rate, and in the coin or currency, herein prescribed. 
  
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register,
upon surrender of this Security for registration of transfer at the office or agency of the Company maintained for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated
transferee or transferees. 
  
 The Securities are issuable only in
registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of
Securities of a different authorized denomination, as requested by the Holder surrendering the same. 
  
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith. 
  
 A director, officer, employee or stockholder of the Company shall not have any personal liability under this Security or the Indenture by reason of his or its status as such director, officer, employee or stockholder.
Each Holder, by accepting this Security, waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of this Security. 
  
 Prior to the time of due presentment of this Security for registration of transfer, the Company, the Trustee and any agent
of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this 
  

 A-6 

 Security is overdue, and neither the Company, the Trustee nor any agent shall be affected by notice to the contrary.

  
 All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture. The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to the Company, 810 Houston Street, Fort Worth, Texas
76102. 
  
 Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders thereof. No representation is made as to the accuracy of such numbers as printed on the
Securities and reliance may be placed only on the other identifying information printed hereon. 
  
 This Security shall be governed by and construed in accordance with the laws of the State of New York, except to the extent the TIA is applicable.
