 SECTION 2.1. Definitions. 
 Section 1.1 of the Original Indenture is amended and supplemented by inserting or restating, as the case may be, in their appropriate alphabetical position, the following definitions: 
 “2010 Notes” means the 5.00% Senior Notes due 2010 of the Company to be issued pursuant to this Indenture.

 “Regular Record Date” for the interest payable on the Notes on any Interest Payment Date means,
with respect to the 2013 Notes and the 2018 Notes, the June 1 or December 1 (whether or not a Business Day) and, with respect to the 2010 Notes, the January 15 or July 15 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. 
 “Make-Whole Amount” with respect to a Note means an amount equal to the excess, if any, of
(1) the present value of the remaining interest, premium and principal payments due on such Note (excluding any portion of such payments of interest accrued as of the Redemption Date), computed using a discount rate equal to the Treasury Rate

similar market data) most nearly equal to the then remaining maturity of such Note; provided that if the Make-Whole Average Life of such Note is not equal to the constant maturity of the United States Treasury security for which a weekly average

Subsidiary of the Company referred to in the preceding clause (i). Any Subsidiary referred to in clause (i) of this paragraph shall be and continue as an MLP Subsidiary until the second anniversary of its organization notwithstanding that it
does not have a class of equity securities listed or eligible for trading on The New York Stock Exchange, the American Stock Exchange or the Nasdaq Stock Market; provided, that such Subsidiary shall cease to be an MLP Subsidiary on such
second anniversary if, on such date, it does not have a class of equity securities so listed or eligible.

 SECTION 2.2. Events of Default. 
 Section 4.1(e) of the Original Indenture is amended to read in its entirety as follows: 
 (e) the occurrence and continuation beyond any applicable grace period of any default in the payment of the principal of (or premium, if any, on) or
interest on any Debt of the Company (other than such Securities) or any Subsidiary when due, or any other default causing acceleration of any Debt of the Company or any Subsidiary; provided that the aggregate principal amount of such Debt
shall exceed $100,000,000; provided further that if any such default is cured or waived or any such acceleration rescinded, or such Debt is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace
period or the occurrence of such acceleration, as the case may be, such Event of Default under this Indenture and any consequential acceleration of such Securities shall be automatically rescinded, so long as such rescission does not conflict with
any judgment or decree. 
 SECTION 2.3. Acceleration of Maturity. 
 Section 4.2 of the Original Indenture is amended by adding the following paragraphs as the second and third paragraphs thereof: 
 Notwithstanding the foregoing to the extent elected by the Company, the sole remedy for an Event of
Default relating to the failure by the Company to comply with the provisions of Section 9.9 shall, for the first 120 days after the occurrence of such an Event of Default, consist exclusively of the right to receive special interest
(“Special Interest”) on the Notes at an annual rate equal to 0.50% of the principal amount of the Notes. Such Special Interest shall be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment
Date following the date on which such Special Interest began to accrue on the Notes. Special Interest shall accrue on all Outstanding Notes from and including the date on which an Event of Default relating to a failure to comply with the provisions
of Section 9.9 shall first occur to but not including the 120th day thereafter (or such earlier date on which such Event of Default shall have
been cured or waived). On such 120th day (or earlier, if the Event of Default relating to the failure to comply with Section 9.9 shall be cured
or waived prior to such 120th day), such Special Interest shall cease to accrue and, if the Event of Default relating to the failure to comply with
Section 9.9 shall not have been cured or waived prior to such 120th day, the Notes shall be subject to acceleration as provided in this
Section 4.2. The provisions of this paragraph shall not affect the rights of holders in the event of the occurrence of any other Event of Default. In the event the Company shall not elect to pay Special Interest upon an Event of Default
resulting from the failure of the Company to comply with the provisions of Section 9.9, the Notes shall be subject to acceleration as provided above in this Section 4.2. 
 If the Company shall elect to pay Special Interest in connection with an Event of Default relating to its failure to comply with the requirements of
Section 9.9, (1) the Company shall notify all Holders and the Trustee and Paying Agent of such election in writing on or before the close of business on the date on which such Event of Default shall first occur, and (2) all references
herein to interest accrued or payable as of any date shall include any Special Interest accrued or payable as of such date as provided in this Section 4.2. 
  

 6 

 SECTION 2.4. Force Majeure. 
 Article XIII of the Original Indenture is amended by adding the following Section 13.15 thereto: 
 SECTION 13.15 Force Majeure. 
 In
no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including strikes, work stoppages,
accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being
understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 
 SECTION 2.5. Waiver of Jury Trial. 
 Article XIII of the Original Indenture is amended by adding the following Section 13.16 thereto: 
 SECTION 13.16
Waiver of Jury Trial. 
 EACH PARTY HERETO WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT.

the “Securities”), which is issued under, with securities of one or more additional series that may be issued under, the Indenture dated as of July 19, 2007, between the Company and The Bank of New York Mellon Trust Company, N.A., as
trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture dated as of July 19, 2007, the Second Supplemental Indenture dated
as of April 18, 2008 and the Third Supplemental Indenture dated as of August 7, 2008 (such Indenture, as so amended and supplemented, being called the “Indenture”), to which Indenture and all future 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. 
 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. 
 In the event of
redemption of this Security in part only, a new Security or Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Securities do not have the benefit of any sinking fund or mandatory repurchase obligations. 
 As set forth in the Indenture, an Event of Default is generally: (a) failure to pay principal upon Stated 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; (d) failure for 30 days after
notice to comply with any other covenants in the Indenture or the Securities; (e) certain payment defaults under, or the acceleration prior to the maturity of, Debt of the Company or any Subsidiary in an aggregate principal amount in excess of
$100,000,000; and (f) certain events of bankruptcy, insolvency or reorganization of the Company. 
  

 A-4 

 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, the principal amount of the Securities will become due and payable immediately without further action or notice, (ii) in the case of an Event of Default which relates to certain payment defaults or acceleration
with respect to certain Debt, any acceleration of the Securities will be automatically rescinded if any such Debt is repaid or if the default relating to such Debt is cured or waived and if the holders thereof have accelerated such Debt then such
holders have rescinded their declaration of acceleration and (iii) in the case of an Event of Default which relates to certain defaults in timely filing reports and documents under the Exchange Act, the Company may elect to pay Special Interest
as the sole remedy for such Event of Default during the first 120 days after the occurrence thereof. 
 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 annual reports with the Trustee as to the absence or existence of defaults. 
 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 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 in any material respect. 
  

 A-5 

 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 registrable 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 transfer tax or similar 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 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 that the Trust Indenture Act is applicable.

 FORM OF REVERSE OF 2013 NOTE 
 This Security is one of a duly authorized issue of the series of securities of the Company designated as its 5.75% Senior Notes due 2013 (herein called
the “Securities”), which is issued under, with securities of one or more additional series that may be issued under, the Indenture dated as of July 19, 2007, between the Company and The Bank of New York Mellon Trust Company, N.A., as
trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture dated as of July 19, 2007, the Second Supplemental Indenture dated
as of April 18, 2008 and the Third Supplemental Indenture dated as of August 7, 2008 (such Indenture, as so amended and supplemented, being called the “Indenture”), to which Indenture and all future 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. 
 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. 
 In the event of
redemption of this Security in part only, a new Security or Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Securities do not have the benefit of any sinking fund or mandatory repurchase obligations. 
 As set forth in the Indenture, an Event of Default is generally: (a) failure to pay principal upon Stated 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; (d) failure for 30 days after
notice to comply with any other covenants in the Indenture or the Securities; (e) certain payment defaults under, or the acceleration prior to the maturity of, Debt of the Company or any Subsidiary in an aggregate principal amount in excess of
$100,000,000; and (f) certain events of bankruptcy, insolvency or reorganization of the Company. 
  

 B-4 

 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, the principal amount of the Securities will become due and payable immediately without further action or notice, (ii) in the case of an Event of Default which relates to certain payment defaults or acceleration
with respect to certain Debt, any acceleration of the Securities will be automatically rescinded if any such Debt is repaid or if the default relating to such Debt is cured or waived and if the holders thereof have accelerated such Debt then such
holders have rescinded their declaration of acceleration and (iii) in the case of an Event of Default which relates to certain defaults in timely filing reports and documents under the Exchange Act, the Company may elect to pay Special Interest
as the sole remedy for such Event of Default during the first 120 days after the occurrence thereof. 
 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 annual reports with the Trustee as to the absence or existence of defaults. 
 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 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 in any material respect.

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.

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.

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.

may require payment of a sum sufficient to cover any transfer tax or similar 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 Security is overdue, and neither the Company, the Trustee nor any agent shall be affected by notice to the contrary.

payment of such interest has been made or duly provided for. In the circumstances indicated in Section 4.2 of the Indenture, the Company may elect to pay Special Interest on this Security, at the rate stated therein, and all references in this
Security to interest accrued or payable as of any date shall include any Special Interest accrued or payable as of such date, as provided in such Section 4.2. 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
June 1 or December 1 (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, and 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 Holder requesting payment by wire transfer and specifying the account to which transfer is requested. Notwithstanding the foregoing, so long as this Security is registered in the name of a
Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of such Depositary or its nominee. The Holder must surrender this Security to a Paying Agent to collect payment of principal.

 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.

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. 
 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its corporate seal.

 FORM OF REVERSE OF 2018 NOTE 
 This Security is one of a duly authorized issue of the series of securities of the Company designated as its 6.50% Senior Notes due 2018 (herein called
the “Securities”), which is issued under, with securities of one or more additional series that may be issued under, the Indenture dated as of July 19, 2007, between the Company and The Bank of New York Mellon Trust Company, N.A., as
trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture dated as of July 19, 2007, the Second Supplemental Indenture dated
as of April 18, 2008 and the Third Supplemental Indenture dated as of August 7, 2008 (such Indenture, as so amended and supplemented, being called the “Indenture”), to which Indenture and all future 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. 
 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. 
 In the event of
redemption of this Security in part only, a new Security or Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Securities do not have the benefit of any sinking fund or mandatory repurchase obligations. 
 As set forth in the Indenture, an Event of Default is generally: (a) failure to pay principal upon Stated 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; (d) failure for 30 days after
notice to comply with any other covenants in the Indenture or the Securities; (e) certain payment defaults under, or the acceleration prior to the maturity of, Debt of the Company or any Subsidiary in an aggregate principal amount in excess of
$100,000,000; and (f) certain events of bankruptcy, insolvency or reorganization of the Company. 
  

 C-4 

 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, the principal amount of the Securities will become due and payable immediately without further action or notice, (ii) in the case of an Event of Default which relates to certain payment defaults or acceleration
with respect to certain Debt, any acceleration of the Securities will be automatically rescinded if any such Debt is repaid or if the default relating to such Debt is cured or waived and if the holders thereof have accelerated such Debt then such
holders have rescinded their declaration of acceleration and (iii) in the case of an Event of Default which relates to certain defaults in timely filing reports and documents under the Exchange Act, the Company may elect to pay Special Interest
as the sole remedy for such Event of Default during the first 120 days after the occurrence thereof. 
 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 annual reports with the Trustee as to the absence or existence of defaults. 
 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 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 in any material respect. 
  

 C-5 

 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 registrable 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 transfer tax or similar 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 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 that the Trust Indenture Act is applicable.
