herein, as follows:


 


Article I


 


SCOPE OF SUPPLEMENTAL INDENTURE; GENERAL; THE
NOTES


 


SECTION 1.1.       Scope
of Supplemental Indenture; General. This Supplemental Indenture supplements, and to the extent inconsistent therewith, replaces, the
provisions of the Base Indenture, to which provisions reference is hereby made.


 


The changes, modifications and
supplements to the Base Indenture effected by this Supplemental Indenture shall be applicable only with respect to, and govern the terms
of, and shall be deemed expressly included in this Supplemental Indenture solely for the benefit of, the Notes (which shall be initially
in the aggregate principal amount of $1,100,000,000) and shall not apply to any other series of Securities that have been or may be issued
under the Base Indenture unless a supplemental indenture with respect to such other series of Securities specifically incorporates such
changes, modifications and supplements.


 



     2


     


    

 


SECTION 1.2.       Applicability
of Sections of the Base Indenture. Except as expressly specified hereby, each of the provisions of the Base Indenture shall apply
to the Notes. The First Supplemental Indenture, dated as of December 5, 2019, the Second Supplemental Indenture, dated as of May 26,
2020, the Third Supplemental Indenture, dated as of March 24, 2021, the Fourth Supplemental Indenture, dated as of June 30,
2021 and the Fifth Supplemental Indenture, dated as of March 17, 2022, in each case, to the Base Indenture shall not be applicable
with respect to, and shall not govern the terms of, the Notes.


 


SECTION 1.3.       Form,
Dating and Terms.


 


(a)            General.
The aggregate principal amount of the Notes that may be authenticated and delivered under the Indenture is unlimited. The aggregate principal
amount of the Initial Notes initially authorized for authentication and delivery pursuant to this Supplemental Indenture is limited to
$1,100,000,000 (except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other
Notes pursuant to Section 1.3(b), 1.3(c) and 8.6 of this Supplemental Indenture and Sections 304,
305, 306 and 1107 of the Base Indenture). Pursuant to this Supplemental Indenture, there is hereby created and designated one series
of Securities under the Indenture entitled “6.250% Senior Notes due 2033.”


 


In addition, with respect to
the Notes, the Company may issue, from time to time subsequent to the Issue Date in accordance with the provisions of the Indenture, additional
Securities (such Securities, the “Additional Notes”) of the same series as the Notes.


 


The Initial Notes and the Additional
Notes shall be considered collectively as a single class for all purposes of the Indenture. Holders of the Initial Notes and the Additional
Notes shall vote and consent together on all matters to which such Holders are entitled to vote or consent as one series of Securities,
and none of the Holders of the Initial Notes or the Additional Notes shall have the right to vote or consent as a separate class or series
on any matter to which such Holders are entitled to vote or consent.


 


Initial Notes and Additional
Notes shall be initially issued in the form of one or more permanent Global Securities substantially in the form of Exhibit A
(each, a “Global Note”), duly executed by the Company and authenticated by the Trustee as provided in the Base Indenture.
The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records
of the Trustee and the Depositary or its nominee.


 


The Notes may have such letters,
numbers or other marks of identification and such notations, legends or endorsements as the officers executing the same may approve (execution
thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Supplemental Indenture or
the Base Indenture or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance,
or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.


 


The terms and provisions contained
in the form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this Supplemental
Indenture, and the Company, the Subsidiary Guarantor and the Trustee, by their execution and delivery of this Supplemental Indenture,
expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with
the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.


 



     3


     


    

 


The Company shall pay principal
of, premium, if any, and interest on the Notes at the office or agency designated by the Company, which is initially the corporate trust
office of the Trustee in Minneapolis, Minnesota. The Company shall pay principal of, premium, if any, and interest on the Global Notes
registered in the name of or held by the Depositary or its nominee in immediately available funds to the Depositary or its nominee, as
the case may be, as the registered holder of such Global Note. The Company shall make all payments in respect of a Definitive Note by
mailing a check to the registered address of each Holder thereof as such address shall appear in the Security Registrar’s books;
provided, however, that payments on the Notes represented by Definitive Notes may also be made, in the case of a Holder
of at least $1,000,000 aggregate principal amount of Notes represented by Definitive Notes, by wire transfer to a U.S. dollar account
maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the
Trustee or the Paying Agent in accordance with the terms of the Indenture.


 


(b)           Book-Entry
Provisions. Except as otherwise stated in this Section 1.3(b) and Section 1.3(c) below, the last
two paragraphs of Section 305 of the Base Indenture will apply to the Notes.


 


(i)           This
Section 1.3(b) shall apply only to Global Notes deposited with the Notes Custodian with respect to such Notes (as appointed
by the Depositary), or any successor Person thereto, which shall initially be the Trustee.


 


(ii)          Each
Global Note initially shall (x) be registered in the name of the Depositary for such Global Note or the nominee of such Depositary,
(y) be delivered to the Notes Custodian for such Depositary and (z) bear the legend set forth in Exhibit A.


 


(iii)         Members
of, or participants in, the Depositary (“Agent Members”) shall have no rights under the Indenture with respect to any
Global Note held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Note, 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
Note 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
impair, as between the Depositary and its Agent Members, the operation of customary practices of the Depositary governing the exercise
of the rights of a Holder of a beneficial interest in any Global Note.


 


(iv)         The
registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes.


 



     4


     


    

 


(v)          In
connection with the transfer of an entire Global Note to beneficial owners pursuant to Section 1.3(c) of this Supplemental
Indenture, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the
Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest
in such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations.


 


(vi)         Any
Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Note may
be effected only through a book-entry system maintained by (a) the Holder of such Global Note (or its agent) or (b) any Holder
of a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be
reflected in a book entry.


 


(c)            Definitive
Notes. Except as provided in the Indenture, owners of beneficial interests in Global Notes shall not be entitled to receive Definitive
Notes. Definitive Notes shall be delivered to all beneficial owners in exchange for their beneficial interests in a Global Note if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as depositary for such Global Note or the Depositary ceases
to be a clearing agency registered under the Exchange Act at a time when the Depositary is required to be so registered in order to act
as Depositary, and, in each case, a successor depositary is not appointed by the Company within 90 days of such notice or (ii) an
Event of Default has occurred and is continuing and the Security Registrar has received a request from the Depositary to deliver Definitive
Notes to all beneficial owners in exchange for their beneficial interests in such Global Note. Definitive Notes may not be exchanged for
beneficial interests in any Global Note unless the transferor first delivers to the Trustee a written certificate to the effect that such
transfer will comply with any appropriate transfer restrictions applicable to such Notes.


 


(d)           Initial
Notes. The Initial Notes may forthwith be executed by the Company and delivered, together with a Company Order, to the Trustee for
authentication and delivery by the Trustee for original issue in accordance with the provisions of Section 303 of the Base Indenture.


 


(e)           Additional
Notes. At any time and from time to time after the issuance of the Initial Notes, the Trustee shall authenticate and deliver any Additional
Notes for original issue in accordance with the provisions of Section 303 of the Base Indenture in an aggregate principal amount
determined at the time of issuance and specified in a Company Order which shall be accompanied with the Officers’ Certificate or
supplemental indenture, as applicable, in respect thereof specified in Section 1.4 of this Supplemental Indenture. Such Company
Order shall specify the principal amount of the Additional Notes to be authenticated and the date on which the original issue of such
Additional Notes is to be authenticated.


 



     5


     


    

 


SECTION 1.4.       Additional
Notes. With respect to any Additional Notes, there shall be set forth or determined in an Officers’ Certificate delivered to
the Trustee or established in one or more indentures supplemental to the Indenture, prior to the issuance of such Additional Notes:


 


(a)            the
aggregate principal amount of such Additional Notes to be authenticated and delivered; and


 


(b)           the
issue price and the issue date of such Additional Notes, including the date from which interest shall accrue and the first interest payment
date therefor.

publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal”
(or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as
applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the
Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal
to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than
and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate
to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal
places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for
the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant
maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable,
of such Treasury constant maturity from the redemption date.


 


If on the third Business Day
preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum

maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date
following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call
Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities
meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities
the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United
States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph,
the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked
prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and
rounded to three decimal places.

REDEMPTION


 


SECTION 3.1.       Optional
Redemption.


 


(a)            Prior
to the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a Redemption
Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (1) (a) the
sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed discounted to the
Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve
30-day months) at the Treasury Rate plus 35 basis points less (b) interest accrued to the Redemption Date, and (2) 100% of the
principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to but not including the Redemption
Date.


 



     13


     


    

 


(b)           On
or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption
Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to but not including
the Redemption Date.


 


(c)            The
Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent
manifest error.


 


(d)           In
the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee
in its sole discretion deems appropriate and fair, subject to the last sentence of this Section 3.1(d). No Notes of a principal amount
of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note
will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion
of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as
the Notes are held by the Depositary, the redemption of the Notes shall be done in accordance with the policies and procedures of such
Depositary.


 


(e)            Unless
the Company defaults in payment of the Redemption Price or any conditions precedent described in the notice of redemption are not satisfied
and therefore the notice of redemption is deemed rescinded, on and after the Redemption Date interest will cease to accrue on the Notes
or portions thereof called for redemption.


 


SECTION 3.2.       Sinking
Fund; Mandatory Redemption. The Company is not required to make mandatory redemption payments or sinking fund payments with respect
to the Notes. Accordingly, Article XII of the Base Indenture shall not apply to the Notes.


 


SECTION 3.3.       Redemption
Provisions.


 


(a)            The
first sentence of Section 1104 of the Base Indenture shall not apply to the Notes, and in lieu thereof, the following sentence shall
be deemed included in the Indenture for the benefit of the Notes:


 


Notice of redemption shall be given
in the manner provided in Section 106 of the Base Indenture at least 10 but not more than 60 days prior to the Redemption Date (or
within such period as otherwise specified in this Supplemental Indenture), to each Holder of Notes to be redeemed, at such Holder’s
address appearing in the Security Register; provided, however, notice of redemption may be given more than 60 days prior to the Redemption
Date (i) when Notes are to be redeemed pursuant to Article IV of the Base Indenture or (ii) as specified in Section 3.3(b) of
this Supplemental Indenture.


 


(b)           Notwithstanding
anything herein to the contrary, notices may be sent more than 60 days prior to a Redemption Date if the notice is issued in connection
with a Covenant Defeasance or Defeasance with respect to the Notes or a satisfaction and discharge of the Indenture with respect to the
Notes.


 



     14


     


    

 


(c)            Notice
of any redemption may, at the Company’s discretion, be subject to one or more conditions precedent. If a redemption is subject to
satisfaction of one or more conditions precedent, the Redemption Date may be delayed up to 10 Business Days at the Company’s election.
If such conditions precedent are not satisfied within 10 Business Days after the proposed Redemption Date, such redemption shall not occur
and the notice thereof shall be deemed rescinded. If the conditions precedent are satisfied, the Company shall provide written notice
to the Trustee of the satisfaction of such conditions as soon as practicable following occurrence of the conditions.


 


(d)            A
notice of redemption need not set forth the exact Redemption Price but only the manner of calculation thereof.


 


(e)            Except
as otherwise stated in this Article III or to the extent inconsistent with this Article III, Article XI of
the Base Indenture shall apply to the Notes.


 


Article IV


 


COVENANTS


 


Articles VII and X of the Base
Indenture shall apply to the Notes, and the covenants in such Articles shall be deemed included in the Indenture for the benefit of the
Notes, except that Section 704 of the Base Indenture shall not apply to the Notes, and the covenants in Section 704 of the Base
Indenture shall be deemed included in the Indenture solely for the benefit of series of Securities other than the Notes.


 


In addition, the following covenants
in this Article IV shall apply to the Notes and shall be deemed included in the Indenture solely for the benefit of the Notes:


 


SECTION 4.1.       Limitation
on Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, create, Incur, or suffer or permit
to exist, any Lien securing Funded Debt (other than Permitted Liens) upon any Principal Property, whether owned on the Issue Date or acquired
after that date, unless the Indebtedness due under the Indenture, the Notes and the Subsidiary Guarantee (if any) is secured equally and
ratably with (or senior in priority to in the case of Liens with respect to Funded Debt that is expressly subordinated to the Notes or
the Subsidiary Guarantee) the Funded Debt secured by such Lien for so long as such Funded Debt is so secured.


 


Notwithstanding the preceding
paragraph, the Company may, and may permit any Restricted Subsidiary of the Company to, create, Incur, or suffer or permit to exist,
any Lien securing Funded Debt upon any Principal Property without securing the Indebtedness due under the Indenture, the Notes and the
Subsidiary Guarantee if the aggregate principal amount of such Funded Debt secured by such Lien upon such Principal Property, together
with the aggregate outstanding principal amount of all other Funded Debt of the Company and of any Restricted Subsidiary of the Company
secured by any Liens (other than Permitted Liens) upon Principal Property, does not at the time such Funded Debt is created, Incurred
or assumed (or, if later, at the time such Lien is created, Incurred or assumed) exceed the greater of (i) 15% of Consolidated
Net Tangible Assets at such time and (ii) $3,350,000,000.


 



     15

Company will furnish or file with the Trustee, within 15 days after it files the same with the SEC, copies of the annual reports and the
information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations
prescribe) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. If the Company
is not subject to the requirements of Section 13 or 15(d) of the Exchange Act, the Company will furnish to all Holders of the
Notes and prospective purchasers of the Notes designated by the Holders of the Notes, promptly on their request, the information required
to be delivered pursuant to Rule 144A(d)(4) promulgated under the Securities Act. For purposes of this Section 4.2,
the Company will be deemed to have furnished such reports and information to, or filed such reports and information with, the Trustee
and the Holders of Notes and prospective purchasers as required by this Section 4.2 if it has filed such reports or information
with the SEC via the EDGAR filing system or otherwise made such reports or information publicly available on a freely accessible page on
the Company’s website. The Trustee shall have no obligation whatsoever to determine whether or not such reports and information
have been filed or have been posted on such website.


 


(b)            The
Company also shall furnish to the Trustee, annually, a brief certificate from the principal executive officer, principal financial officer
or principal accounting officer as to his or her knowledge of the Company’s compliance with all conditions and covenants under the

Company will deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any events that would constitute an
Event of Default, unless such Event of Default has been cured or waived before the end of such 30-day period, their status and what action
the Company is taking or proposing to take in respect thereof.


 


(d)            Delivery
of any reports, information and documents to the Trustee pursuant to paragraphs (a) and (b) above is for informational purposes
only and the Trustee’s receipt of such shall not constitute notice, constructive or otherwise, of any information contained therein
or determinable from information contained therein, including the compliance by the Company with any of the Company’s covenants
(as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).


 


SECTION 4.3
Unrestricted Subsidiaries.


 


(a)            The
Board of Directors of the Company may after the Issue Date designate any Subsidiary as an “Unrestricted Subsidiary” if: (1) no
Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such designation; and (2) such
Subsidiary has no Indebtedness other than Non-Recourse Debt.


 


(b)            The
Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company.
Any such designation will be deemed to be an incurrence of Funded Debt and Liens by a Restricted Subsidiary of the Company of any outstanding
Funded Debt and Liens, respectively, of such Unrestricted Subsidiary, and such designation will only be permitted if no Default or Event
of Default would be in existence following such designation.

of Default.


 


(a)            Each

(5)          default
under any mortgage, indenture or similar instrument under which there is issued or by which there is secured or evidenced any Indebtedness
for money borrowed by the Company or the Subsidiary Guarantor (or the payment of which is guaranteed by the Company or the Subsidiary
Guarantor), other than Indebtedness owed to a Subsidiary, whether such Indebtedness or guarantee now exists or is created after the Issue
Date, which default:


 



     17


     


    

 


(A)            is
caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period
provided in such Indebtedness (“payment default”); or


 


(B)            results
in the acceleration of such Indebtedness prior to its maturity;


 


and, in each case, the principal amount
of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there is an outstanding uncured
payment default or the maturity of which has been and remains so accelerated, aggregates $150.0 million or more;


 


(6)            the
Company, pursuant to or within the meaning of any Bankruptcy Law:


 


(A)           commences
a voluntary case or voluntary proceeding;


 


(B)            consents
to the entry of a judgment, decree or order for relief against it in an involuntary case or involuntary proceeding;


 


(C)            consents
to the appointment of a Custodian of it or for any substantial part of its property;


 


(D)            makes
a general assignment of substantially all of its property for the benefit of its creditors; or


 


(E)            transmits
its written consent to or acquiescence in the institution of a bankruptcy proceeding or other collective proceeding for relief by or against
its creditors generally;

(A)           is
for relief in an involuntary case against the Company, pursuant to or within the meaning of the Bankruptcy Law;


 


(B)           appoints

     18


     


    

 


(8)          the
Subsidiary Guarantee ceases to be in full force and effect (except as contemplated by the terms of the Indenture) or is declared null
and void in a judicial proceeding or the Subsidiary Guarantor denies or disaffirms its obligations under the Indenture or the Subsidiary
Guarantee, in each case unless the Subsidiary Guarantee has been released pursuant to the terms of the Indenture.


 


(b)           Notwithstanding
Section 6.1(a), a default under Section 6.1(a)(3) or Section 6.1(a)(4) will not constitute
an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the then Outstanding Notes notify the Company
in writing of the Default and the Company does not cure such Default within the time specified in Section 6.1(a)(3) or
Section 6.1(a)(4) after receipt of such notice. Such notice must specify the Default, demand that it be remedied, and
state that such notice is a “Notice of Default.”


 


SECTION 6.2.       Acceleration
of Maturity; Rescission and Annulment.


 


If an Event of Default (other
than an Event of Default described in Section 6.1(a)(6) or (7)) occurs and is continuing, the Trustee by written
notice to the Company, or Holders of at least 25% in principal amount of the then outstanding Notes by written notice to the Company and
the Trustee, may, and the Trustee at the request of Holders of at least 25% in principal amount of the then Outstanding Notes shall, declare
the principal, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable. Such notice must specify
the Event of Default and state that such notice is a “Notice of Acceleration.” Upon such a declaration, such principal, premium,
if any, and accrued and unpaid interest will be due and payable immediately.


 


In the event of a declaration
of acceleration of the Notes because an Event of Default described in Section 6.1(a)(5) has occurred and is continuing,
the declaration of acceleration of the Notes shall be automatically annulled if the Default triggering such Event of Default pursuant
to Section 6.1(a)(5) shall be remedied or cured by the Company or waived by the Holders of the relevant Indebtedness
within 20 days after the written notice of declaration of acceleration of the Notes with respect thereto is received by the Company and
if (1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction
and (2) all existing Events of Default, except nonpayment of principal, premium, if any, or interest on the Notes that became due
solely because of the acceleration of the Notes, have been cured or waived.


 


If an Event of Default pursuant
to Section 6.1(a)(6) or (7) occurs, the principal, premium, if any, and accrued and unpaid interest on all
the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.


 


At any time after a declaration
of acceleration, but before a judgment or decree for the payment of the money due has been obtained by the Trustee, the Holders of a majority
in principal amount of the Outstanding Notes may by notice to the Trustee and the Company (including, without limitation, waivers and
consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) waive all past defaults (except with
respect to nonpayment of principal, premium, if any, or interest) and rescind any such acceleration with respect to the Notes and its
consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all
existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become
due solely by such declaration of acceleration, have been cured or waived.

of Notes) and Section 801 of the Base Indenture (other than Section 8.01(2)) and (ii) the events described in Section 6.1(a),
clauses (3), (4), (5) and (8) of this Supplemental Indenture shall no longer constitute Events of Default with respect
to Notes.


 


If the Company exercises its
Defeasance or its Covenant Defeasance option or satisfies and discharges the Indenture with respect to the Notes, in each case all Guarantees
(if any are in effect at such time) will terminate.


 


Article VIII


 


AMENDMENT, SUPPLEMENT AND WAIVER


 


Article IX of the Base
Indenture shall not apply to the Notes, provided that nothing in this Supplemental Indenture shall limit or affect the provisions of Article IX
of the Base Indenture (including Section 901(5) and Section 901(7) thereof) insofar as relating to any amendment or
waiver in respect of any series of Securities other than the Notes.


 


SECTION 8.1.       Without
Consent of Holders. Notwithstanding Section 8.2 and Section 8.3, without the consent of any Holder of Notes,
the Company and the Trustee may amend or supplement this Supplemental Indenture, the Base Indenture as it relates to the Notes (including

(1)          cure
any ambiguity, omission, defect or inconsistency;


 


(2)          provide
for the assumption by a successor entity of the obligations of the Company under this Supplemental Indenture, the Base Indenture (as it
relates to the Notes) or the Notes in accordance with Section 801 and Section 802 of the Base Indenture;


 


(3)          provide
for or facilitate the issuance of uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated
Notes are issued in registered form for purposes of Section 163(f) of the Code);


 


(4)          add
Guarantees with respect to the Notes, evidence the release of a Guarantor from its Guarantee or provide for the assumption by a successor

     20


     


    

 


(5)          secure
the Notes or any Guarantee thereof;


 


(6)          add
covenants of the Company or other obligor under the Indenture or the Notes or any Guarantees, as the case may be, or Events of Default
for the benefit of the Holders of the Notes or the Guarantee or to make other changes that would provide additional rights to the Holders
of the Notes or to surrender any right or power conferred upon the Company or other such obligor;


 


(7)          make
any change that does not adversely affect the legal or contractual rights of any Holder under the Indenture or the Notes;


 


(8)          evidence
and provide for the acceptance of an appointment under the Indenture of a successor trustee; provided that the successor trustee
is otherwise qualified and eligible to act as such under the terms of the Indenture;


 


(9)          provide
for the issuance of Additional Notes permitted to be issued under the Indenture;


 


(10)        comply
with the rules of any applicable securities depositary; or


 


(11)        conform
the text of this Supplemental Indenture, the Base Indenture (as it relates to the Notes and the Subsidiary Guarantee), the Notes or the
Guarantee to any provision of the section of the Company’s Prospectus Supplement dated October 17, 2022 entitled “Description
of Notes” or the “Description of Debt Securities” set forth in the accompanying base prospectus to the extent that such
provision in the “Description of Notes” or the “Description of Debt Securities” was intended to be a verbatim
recitation of a provision of the Indenture, the Notes or the Guarantee, which intent shall be established by an Officers’ Certificate.


 


After an amendment, supplement
or waiver under the Indenture becomes effective, the Company is required to send to the Holders a notice briefly describing such amendment,
supplement or waiver. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect
the validity of any amendment, supplement or waiver.


 


SECTION 8.2.       With
Consent of Holders. Except as set forth in Section 8.1 and Section 8.3, the Company and the Trustee may amend
or supplement this Supplemental Indenture, the Base Indenture (as it relates to the Notes) and the Notes with the consent of the Holders
of a majority in principal amount of the Notes then Outstanding voting as a single class (including, without limitation, consents obtained
in connection with a purchase of, or tender offer or exchange offer for, Notes) and any past default or compliance with any provisions
of this Supplemental Indenture, the Base Indenture (as it relates to the Notes) and the Notes may be waived with the consent of the Holders
of a majority in principal amount of the Notes then Outstanding voting as a single class (including, without limitation, consents obtained
in connection with a purchase of, or tender offer or exchange offer for, Notes).


 


The consent of the Holders is
not necessary under the Indenture to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if
such consent approves the substance of the proposed amendment, supplement or waiver. A consent to any amendment, supplement or waiver
under the Indenture by any Holder of Notes given in connection with a tender of such Holder’s Notes will not be rendered invalid
by such tender.


 



     21


     


    

 


SECTION 8.3.       Limitations.
Notwithstanding Section 8.2, without the consent of each Holder of an Outstanding Note affected, no amendment, supplement
or waiver may (with respect to any Notes held by a non-consenting Holder):


 


(1)          reduce
the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;


 


(2)          reduce
the stated rate of interest or extend the stated time for payment of interest on any Note;


 


(3)          reduce
the principal of or extend the Stated Maturity of any Note;


 


(4)          waive
a Default or Event of Default in the payment of principal of, premium, if any, or interest on the Notes (except a rescission of acceleration
of the Notes by Holders of a majority in aggregate principal amount of the then outstanding Notes with respect to a nonpayment default
and a waiver of the payment default that resulted from such acceleration);


 


(5)          reduce
the premium payable upon the redemption of any Note or change the time at which any Note may be redeemed as described under Article III,
whether through an amendment or waiver of Article III, related definitions or otherwise;


 


(6)          make
any Note payable in money other than that stated in the Note;


 


(7)          impair
the right of any Holder to receive payment of principal, premium, if any, and interest on such Holder’s Notes on or after the due
dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes;


 


(8)          modify
the Subsidiary Guarantee of the Notes in any manner adverse to the Holders of the Notes; or


 


(9)          make
any change in the amendment or waiver provisions that require each Holder’s consent.


 


SECTION 8.4.       Compliance
with Trust Indenture Act. Every amendment to this Supplemental Indenture, the Base Indenture (as it relates to the Notes) or the Notes
shall be set forth in a supplemental indenture hereto that complies with the Trust Indenture Act as then in effect. The Trustee shall
have no responsibility or liability for whether this Supplemental Indenture, the Base Indenture, the Notes, or any amendment to any of
them complies with the Trust Indenture Act or the Company’s compliance with the Trust Indenture Act.


 


SECTION 8.5.       Revocation
and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of Notes is a continuing
consent by the Holder and every subsequent Holder of the Notes or portion of such Notes that evidences the same debt as the consenting
Holder’s Note or Notes, even if notation of the consent is not made on any such Note. However, any such Holder or subsequent Holder
may revoke the consent as to its Notes or portion of such Notes if the Trustee receives the notice of revocation before the date the amendment
or waiver becomes effective.


 



     22


     


    

 


Any amendment or waiver in respect
of the Notes once effective shall bind every Holder of Notes affected by such amendment or waiver unless it is of the type described in
any of the clauses of Section 8.3. In that case, the amendment or waiver shall bind each Holder of a Note who has consented
to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note.


 


The Company may, but shall not
be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action
described above or required or permitted to be taken pursuant to this Supplemental Indenture in respect of the Notes or the Base Indenture
(as it relates to the Notes). If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were
Holders of Notes at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent
or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders of Notes after
such record date.


 


SECTION 8.6.       Notation
on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment or waiver on the Notes. The Company in exchange
for the Notes may issue and the Trustee shall authenticate upon written request new Notes that reflect the amendment or waiver.


 


SECTION 8.7.       Effect
of Supplemental Indenture. Upon the execution of any supplemental indenture under this Article VIII, the Indenture (including
this Supplemental Indenture) shall be modified in accordance therewith, and such supplemental indenture shall form a part of the Indenture
for all purposes; and, subject to Section 8.3, every Holder of Notes theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.


 


Article IX


 


SUBSIDIARY GUARANTEE


 


Article XIV of the Base
Indenture shall apply to the Notes, except as described in this Article IX. The Notes will be fully and unconditionally Guaranteed
(such Guarantee, the “Subsidiary Guarantee”) by Diamondback E&P LLC (such entity during the period (and only during
such period) that the Subsidiary Guarantee is in effect, the “Subsidiary Guarantor”) as a “Guarantor” as
defined in the Base Indenture.


 



     23


     


    

 


SECTION 9.1.       Release
of a Guarantor. Solely with respect to the Notes, the ninth paragraph of Section 1401 of the Base Indenture shall not apply to
the Notes and instead the following shall apply:


 


The Subsidiary Guarantor shall
be released and discharged automatically and unconditionally from all its obligations under the Indenture and its Guarantee with respect
to the Notes, and will cease to be a Guarantor with respect to the Notes, without any further action required on the part of the Trustee
or any Holder, (a) upon the release or discharge of the Company’s Guarantee of the Subsidiary Guarantor’s obligations
under its revolving credit facility (as amended, modified, restated, amended and restated or otherwise replaced or refinanced from time
to time, the “Subsidiary Credit Facility”), (b) upon the release or discharge of the Subsidiary Guarantor’s
obligations under the Subsidiary Credit Facility, (c) in connection with any Covenant Defeasance or Defeasance pursuant to Article XIII
of the Base Indenture as to the Notes or satisfaction and discharge of the Notes pursuant to Article IV of the Base Indenture and
Article VII of this Supplemental Indenture, or (d) if no Event of Default has occurred and is then continuing, upon the
liquidation or dissolution of the Subsidiary Guarantor.


 


In the event the Subsidiary
Guarantor is sold or disposed of (whether by merger, consolidation, the sale of a sufficient amount of its (or an intermediate holding
company’s) Capital Stock so that the Subsidiary Guarantor no longer constitutes a Subsidiary of the Company or the sale of all or
substantially all of its assets (other than by lease)), and whether or not the Subsidiary Guarantor is the surviving entity in such transaction,
to a Person that is not (and does not thereupon become) the Company or a Subsidiary of the Company, the Subsidiary Guarantor will be released
and discharged automatically and unconditionally from all its obligations under the Subsidiary Guarantee and will cease to be the Subsidiary
Guarantor, without any further action required on the part of the Trustee or any Holder.


 


Upon delivery by the Company
to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that any of the conditions described above has
occurred, the Trustee shall execute any supplemental indenture or other documents reasonably requested by the Company in order to evidence
the release of the Subsidiary Guarantor from its obligations under the Subsidiary Guarantee and the Indenture as to the Notes.


 


SECTION 9.2.       Guarantee
Evidenced by Indenture; No Notation of Guarantee.


 


(a)            The
Subsidiary Guarantee of the Subsidiary Guarantor shall be evidenced solely by its execution and delivery of this Supplemental Indenture
and not by an endorsement on, or attachment to, any Note or any Guarantee or notation thereof.


 


(b)            The
delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee
as to the Notes set forth in this Supplemental Indenture on behalf of the Subsidiary Guarantor as to the Notes.

1.            Interest


 


Diamondback Energy, Inc.,
a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called
the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above.


 


The Company shall pay interest
semiannually on March 15 and September 15 of each year, commencing March 15, 2023. Interest on the Notes shall accrue from
the most recent date to which interest has been paid on the Notes or, if no interest has been paid, from October 28, 2022. The Company
shall pay interest on overdue principal or premium, if any (plus interest on overdue installments of interest to the extent lawful), at
the rate borne by the Notes to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day
months.


 


2.            Method
of Payment


 


By
no later than 12:30 p.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is
due and payable, the Company shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal, premium,
if any, or interest. The Company shall pay interest (except Defaulted Interest) to the Persons who are registered Holders at the close
of business on the March 1 or September 1 immediately preceding the interest payment date even if the Notes are cancelled or
repurchased after the Regular Record Date and on or before the Interest Payment Date. Holders must surrender the Notes to a Paying Agent

however, that payments on the Notes represented by Definitive Notes may also be made, in the case of a Holder of at least $1,000,000
aggregate principal amount of Notes represented by Definitive Notes, by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying
Agent in accordance with the terms of the Indenture.

of its Subsidiaries may act as Paying Agent or Security Registrar.


 


4.            Indenture


 


The Company issued the Notes
as a series of Securities under the Indenture dated as of December 5, 2019 (the “Base Indenture”) between the
Company and Wells Fargo Bank, National Association, as predecessor trustee to the Trustee under the Base Indenture, as supplemented by
the Sixth Supplemental Indenture dated as of October 28, 2022 (the “Supplemental Indenture” and, together with
the Base Indenture and any one or more additional supplemental indentures thereto, herein called the “Indenture”) among
the Company, Diamondback E&P LLC, a Delaware limited liability company (the “Subsidiary Guarantor”), and the Trustee.
The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to
all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of those terms. In the event of
any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.


 


The aggregate principal amount
of Notes that may be authenticated and delivered under the Indenture is unlimited. This Note is one of the 6.250% Senior Notes due 2033
referred to in the Indenture. The Notes include (i) $1,100,000,000 aggregate principal amount of the Company’s 6.250% Senior
Notes due 2033 issued under the Indenture on October 28, 2022 in an offering registered under the Securities Act (the “Initial
Notes”), and (ii) if and when issued, an unlimited principal amount of additional 6.250% Senior Notes due 2033 that may
be issued from time to time, under the Indenture, subsequent to October 28, 2022 (the “Additional Notes” and,
together with the Initial Notes, the “Notes”). The Initial Notes and the Additional Notes shall be considered collectively
as a single series of Securities for all purposes of the Indenture.


 


5.            Redemption


 


(a)            Prior
to December 15, 2032 (the “Par Call Date”), the Company may redeem the Notes at its option, in whole or in part,
at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places)
equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest
on the Notes to be redeemed discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 35 basis points less (b) interest accrued
to the Redemption Date, and (2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid
interest thereon to but not including the Redemption Date.


 


(b)            On
or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption
Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to but not including
the Redemption Date.


 



     A-6


     


    

 







6.            Denominations;
Transfer; Exchange


 


The Notes are in registered
form without coupons in denominations of principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. A Holder may
transfer or exchange Notes in accordance with the Indenture. The Security Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by the Company, the Trustee or the
