 In connection with any transfer of
Notes, or of any transfer of a beneficial interest in one global Note to another global Note, as the case may be, the Trustee, the Security Registrar and the Company shall be under no duty to inquire into, may conclusively presume the correctness
of, and shall be fully protected in relying upon the certificates and other information (in the form attached hereto as Exhibit A, for use in connection with the transfer of the Notes in certificated form, or Exhibit B, for use in connection with
the transfer of beneficial interests in one certificate in global form to another certificate in global form or to a Note in certificated form, or otherwise) received from the Holders and any transferees of any Notes, or from the transferors or
transferees of any beneficial interest in a global Note transferred to another global Note, as the case may be, regarding the validity, legality and due authorization of any such transfer, the eligibility of the transferee to receive such Note or
such beneficial interest, as the case may be, and any other facts and circumstances related to such transfer; 
  

	15.	None of the Company, the Trustee or the Security Registrar shall have any liability for any acts or omissions of the Depositary, for any Depositary records of beneficial interests, for any transactions between the
Depositary or any participant member of the Depositary and/or beneficial owners, for any transfers of beneficial interests in the Notes, or in respect of any transfers effected by the Depositary or by any participant member of the Depositary or any
beneficial owner of any interest in any Notes held through any such participant member of the Depositary;

shall not deliver an Officer’s Certificate described in clause (z) in the first paragraph of said Section 801 unless the Company shall also deliver to the Trustee, together with such Officer’s Certificate, either:

Section 801), if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or Eligible Obligations theretofore so deposited, to pay when due the principal of and premium, if any, and interest due
and to become due on such Notes or portions thereof, all in accordance with and subject to the provisions of said Section 801; provided, however, that such instrument may state that the obligation of the Company to make additional deposits as
aforesaid shall be subject to the delivery to the Company by the Trustee of a notice asserting the deficiency accompanied by an opinion of an independent public accountant of nationally recognized standing, selected by the Trustee, showing the
calculation thereof; or

certificate, the Holders of such Notes, or portions of the principal amount thereof, will not recognize income, gain or loss for United States federal income tax purposes as a result of the satisfaction and discharge of the Company’s
indebtedness in respect thereof and will be subject to United States federal income tax on the same amounts, at the same times and in the same manner as if such satisfaction and discharge had not been effected. 

 

	17.	The Eligible Obligations with respect to the Notes shall be Government Obligations.

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

	11.	No service charge shall be made for the registration of transfer or exchange of the Notes; provided, however, that the Company may require payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with the exchange or transfer; 

  

	12.	The Notes of each series shall be initially issued in global form registered in the name of Cede & Co. (as nominee for The Depository Trust Company (“ DTC”)); provided, that the Company
reserves the right to provide for another depositary, registered as a clearing agency under the Exchange Act, to act as depositary for the global Notes (DTC and any such successor depositary, and any successor to any thereto, the
“Depositary”); beneficial interests in Notes issued in global form may not be exchanged in whole or in part for individual certificated Notes in definitive form, and no transfer of a global Note in whole or in part may be registered
in the name of any Person other than the Depositary or its nominee except that (i) if the Depositary (A) has notified the Company that it is unwilling or unable to continue as depositary for the global Notes or (B) has ceased to be a
clearing agency registered under the Exchange Act and, in either case, a successor depositary for such global Notes has not been appointed within 90 days, the Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive Notes, will authenticate and deliver Notes in definitive certificated form in an aggregate principal amount equal to the aggregate principal amount of the global Notes representing such Notes in exchange for
such global Notes, such definitive Notes to be registered in the names provided by the Depositary; each global Note (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the outstanding Notes to be
represented by such global Note, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary, its nominee, any custodian for the Depositary or otherwise pursuant to the
Depositary’s instruction and (iv) shall bear a legend restricting the transfer of such global Note to any Person other than the Depositary or its nominee; none of the Company, the Trustee, any Paying Agent, any Security Registrar or any
Authenticating Agent will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, or transfers of, beneficial ownership interests in a global Note or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests; and the Notes in global form will contain restrictions on transfer, substantially as described in the forms set forth in Exhibit A and Exhibit B hereto; 

 

	13.	 The Notes of each series will be initially issued pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities
Act”). Each Note, whether in a global form or in a certificated form, shall bear the non-registration legend and the registration rights legend in substantially the form set forth in such applicable form, unless otherwise agreed to by the
Company, such agreement to be confirmed in writing to the Trustee. DTC or its nominee shall be the Holder of such applicable global Note for all purposes under the Indenture and the Notes, and beneficial owners with respect to such applicable global
Note shall hold their interests pursuant to applicable procedures of the Depositary. The Company, the Trustee and the Security Registrar shall be entitled to 

  
 3 

	 	
deal with the Depositary for all purposes of the Indenture relating to such applicable global Note (including the payment of principal, premium, if any, and interest, and the giving of
instructions or directions by or to the beneficial owners of such global Note) as the sole Holder of such applicable global Note and shall have no obligations to the beneficial owners thereof. Nothing in the Indenture, the Notes or this certificate
shall be construed to require the Company to register any Notes under the Securities Act, unless otherwise expressly agreed by the Company, confirmed in writing to the Trustee, or to make any transfer of such Notes in violation of applicable law.
The Company has entered into a registration rights agreement with the initial purchasers of the Notes pursuant to which, among other things, the Notes may be exchanged for notes registered under the Securities Act (the “Exchange
Notes”). The Exchange Notes shall be in substantially the form of Exhibit A with respect to the 2025 Notes, and Exhibit B, with respect to the 2045 Notes, but, in each case without the non-registration legend, the registration rights
legend, the Certificate of Transfer and the provisions for Additional Interest. The Trustee, at the request of the Company, shall authenticate and deliver Exchange Notes in exchange for an equal principal amount of Notes of such series;

  

	14.	It is contemplated that beneficial interests in Notes of each series owned by “qualified institutional buyers” (as defined in Rule 144A under the Securities Act) (“QIBs”) or sold to QIBs in
reliance upon Rule 144A under the Securities Act will be represented by one or more separate certificates in global form registered in the name of Cede & Co., as registered owner and as nominee for DTC; beneficial interests in Notes of each
series sold to foreign purchasers pursuant to Regulation S under the Securities Act will be evidenced by one or more separate certificates in global form (each a “Regulation S Global Certificate”) and will be registered in the name
of Cede & Co., as registered owner and as nominee for DTC for the accounts of Euroclear and Clearstream Banking; 

 In
connection with any transfer of Notes, or of any transfer of a beneficial interest in one global Note to another global Note, as the case may be, the Trustee, the Security Registrar and the Company shall be under no duty to inquire into, may
conclusively presume the correctness of, and shall be fully protected in relying upon the certificates and other information (in the form attached hereto as Exhibit A and B, for use in connection with the transfer of the Notes in certificated form,
or Exhibit C, for use in connection with the transfer of beneficial interests in one certificate in global form to another certificate in global form or to a Note in certificated form, or otherwise) received from the Holders and any transferees of
any Notes, or from the transferors or transferees of any beneficial interest in a global Note transferred to another global Note, as the case may be, regarding the validity, legality and due authorization of any such transfer, the eligibility of the
transferee to receive such Note or such beneficial interest, as the case may be, and any other facts and circumstances related to such transfer; 
  

	15.	None of the Company, the Trustee or the Security Registrar shall have any liability for any acts or omissions of the Depositary, for any Depositary records of beneficial interests, for any transactions between the
Depositary or any participant member of the Depositary and/or beneficial owners, for any transfers of beneficial interests in the Notes, or in respect of any transfers effected by the Depositary or by any participant member of the Depositary or any
beneficial owner of any interest in any Notes held through any such participant member of the Depositary; 

  
 4 

	16.	If the Company shall make any deposit of money and/or Eligible Obligations with respect to any Notes, or any portion of the principal amount thereof, as contemplated by Section 801 of the Indenture, the Company
shall not deliver an Officer’s Certificate described in clause (z) in the first paragraph of said Section 801 unless the Company shall also deliver to the Trustee, together with such Officer’s Certificate, either:

 (A) an instrument wherein the Company, notwithstanding the satisfaction and discharge of its indebtedness in respect of such
Notes, shall assume the obligation (which shall be absolute and unconditional) to irrevocably deposit with the Trustee or Paying Agent such additional sums of money, if any, or additional Eligible Obligations (meeting the requirements of
Section 801), if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or Eligible Obligations theretofore so deposited, to pay when due the principal of and premium, if any, and interest due
and to become due on such Notes or portions thereof, all in accordance with and subject to the provisions of said Section 801; provided, however, that such instrument may state that the obligation of the Company to make additional deposits as
aforesaid shall be subject to the delivery to the Company by the Trustee of a notice asserting the deficiency accompanied by an opinion of an independent public accountant of nationally recognized standing, selected by the Trustee, showing the
calculation thereof; or 
 (B) an Opinion of Counsel to the effect that, as a result of a change in law occurring after the date of this
certificate, the Holders of such Notes, or portions of the principal amount thereof, will not recognize income, gain or loss for United States federal income tax purposes as a result of the satisfaction and discharge of the Company’s
indebtedness in respect thereof and will be subject to United States federal income tax on the same amounts, at the same times and in the same manner as if such satisfaction and discharge had not been effected. 

 

	17.	The Eligible Obligations with respect to the Notes of each series shall be Government Obligations. 

  

	18.	The 2025 Notes shall have such other terms and provisions as are provided in the form thereof set forth in Exhibit A hereto, and the 2045 Notes shall have such other terms and provisions as are provided in the form
thereof set forth in Exhibit B hereto; 

  

	19.	No Event of Default under the Indenture has occurred or is occurring; and to the knowledge of the undersigned, (i) no Event of Default has occurred and is continuing and (ii) no event has occurred and is
continuing which entitles the Secured Parties (as defined in the Deed of Trust) under the Deed of Trust, or any of them, to accelerate the maturity of the indebtedness secured thereby; 

 

	20.	 Subject to Section 22 of the Deed of Trust, the aggregate principal amount of indebtedness issuable under and secured by the Deed of Trust is
unlimited, and the 

  
 5 

	 	
aggregate principal indebtedness now proposed to be issued under and secured by the Deed of Trust is $8,100,000,000, consisting of Indenture Notes Obligations (as defined in the Deed of Trust) in

of $2,400,000,000; 

  

	21.	The undersigned has read all of the covenants and conditions contained in the Indenture, and the definitions in the Indenture relating thereto, relating to the issuance and authentication and delivery of the Notes and
to the creation or existence of Secured Debt pursuant to Section 707(a) and Section 707(b) of the Indenture, and in respect of compliance with which this certificate is made; 

 

	22.	The statements contained in this certificate are based upon the familiarity of the undersigned with the Indenture, the documents accompanying this certificate, and upon discussions by the undersigned with officers and

	23.	In the opinion of the undersigned, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenants and conditions have been complied with;

the term “interest” shall be deemed to include any such Additional Interest. In the event that any Interest Payment Date is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is
a Business Day (and without any interest or other payment in respect of such delay) with the same force and effect as if made on the Interest Payment Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment

not so punctually 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

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 a majority in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of
Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and 

  
 B-6 

 
shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of
this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 

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

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000
in excess thereof. As provided in the Indenture and subject to certain limitations therein and herein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of
authorized denominations, 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. 

The Company shall not be required to execute and the Security Registrar shall not be required to register the transfer of or exchange of
(a) Securities of this series during a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities of this series called for redemption or (b) any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed in part. The Company shall not be required to make transfers or exchanges of the Securities of this series for a period of 15 days next preceding an Interest Payment
Date. 
 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 absolute 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. 

Each Holder shall be deemed to understand that the offer and sale of the Securities of this series have not been registered under the
Securities Act and that the Securities of this series may not be resold, pledged or otherwise transferred other than as permitted in the following sentence. Each Holder shall be deemed to agree, on its own behalf and on behalf of any accounts for
which it is acting as hereinafter stated, that if such Holder resells, pledges or otherwise transfers any Securities of this series, such Holder will do so only (A) to the Company, (B) in a transaction entitled to an exemption from
registration provided by Rule 144 under the Securities Act, (C) so long as Securities of this series are eligible for resale pursuant to Rule 144A under the Securities Act, to a Person whom such Holder reasonably believes is a “qualified
institutional buyer” within the meaning of Rule 144A that purchases for its own account or for the account of a qualified institutional buyer to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A,
(D) in an offshore transaction in accordance with Rule 903 or Rule 904 of Regulation S under the Securities Act, (E) in accordance with another applicable exemption from the registration requirements of the Securities Act (and based upon
an opinion of 

  
 B-7 

 
counsel acceptable to the Company), or (F) pursuant to an effective registration statement under the Securities Act, and each Holder is further deemed to agree to provide to any Person
purchasing any of the Securities of this series from it a notice advising such purchaser that resales of the Securities of this series are restricted as stated herein. 

Each Holder shall be deemed to understand that, on any proposed resale of any Securities of this series pursuant to the exemption from
registration under Rule 144 under the Securities Act, any Holder making any such proposed resale will be required to furnish to the Trustee and the Company such certifications, legal opinions and other information as the Trustee and the Company may
reasonably require to confirm that the proposed sale complies with the foregoing restrictions. 
 This Security shall be governed by and
construed in accordance with the laws of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act shall be
applicable and except to the extent that the laws of the State of Texas shall mandatorily govern. 
 As provided in the Indenture, no
recourse shall be had for the payment of the principal of or premium, if any, 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 Indenture, against, and no personal liability whatsoever shall attach to, or be incurred by, any incorporator, stockholder, member, 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 part of
the consideration for, the execution of the Indenture and the issuance of the Securities. 
 Unless the certificate of authentication hereon
has been executed by the Trustee referred to herein 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.
