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 $1,200,000,000) 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.

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 13, 2022, and the Second Supplemental Indenture, dated as of April 18, 2024, 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 $1,200,000,000 (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 “5.550% Senior Notes due 2035.”

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 any Additional Notes shall be considered collectively as a single class for all purposes of the Indenture. Holders of the Initial Notes and any 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 officer 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.

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 St. ▇▇▇▇, 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.

(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 Officer’s 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.

SECTION 1.4. Additional Notes. With respect to any Additional Notes, there shall be set forth or determined in an Officer’s 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.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the date of the notice of redemption relating to such Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or 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 date of the notice of redemption relating to such Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding the date of such notice of redemption of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a 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.

“Unrestricted Subsidiary” means (1) Viper Energy Partners GP LLC, Viper Energy, Inc., Viper Energy Partners LLC, (2) Rattler Midstream GP LLC, Rattler Midstream LP, Rattler Midstream Operating LLC, (3) the respective Subsidiaries from time to time of the Persons referenced in clauses (1) and (2), (4) any other Subsidiary of the Company designated as such pursuant to and in compliance with the Indenture and (5) any Subsidiary of an Unrestricted Subsidiary.

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 20 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.

(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 Notes will state the portion of the principal amount of the Notes 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 or waived and the notice of redemption is rescinded in accordance with Section 3.3(b), 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 paragraph of Section 1104 of the Base Indenture shall not apply to the Notes, and in lieu thereof, the following paragraph shall be deemed included in the Indenture for the benefit of the Notes:

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s Applicable Procedures) in the manner provided in Section 106 of the Base Indenture at least 10 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed. 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 or in accordance with Section 3.3(b) of this Supplemental Indenture.

(b) Notice of any redemption may, at the Company’s discretion, be subject to one or more conditions precedent. If any such condition precedent has not been satisfied or waived, the Company shall provide written notice to the Trustee prior to the close of business one Business Day prior to the Redemption Date (or such shorter period as may be acceptable to the Trustee). Upon receipt of such notice, notwithstanding anything herein to the contrary, the notice of redemption shall be rescinded or delayed, and the redemption of the Notes shall be rescinded or delayed as provided in such notice. Upon receipt, the Trustee shall provide such notice to each Holder in the same manner in which the notice of redemption was given. A notice of redemption need not set forth the exact redemption price but only the manner of calculation thereof.

(d) 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 Sections 704 and 1005 of the Base Indenture shall not apply to the Notes, and the covenants in Sections 704 and 1005 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 (as it relates to the Notes and the Subsidiary Guarantee), the Notes and the Subsidiary Guarantee (if any) are 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) $9,250,000,000.

SECTION 4.2. Reports.

(a) The Company will furnish or file with the Trustee, (i) 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 and (ii) other information, documents, or reports as may be required pursuant to the Trust Indenture Act at the times and in the manner provided in the Trust Indenture 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, if applicable, any other Persons) as required by this Section 4.2 if it has filed such reports or information with the SEC via the ▇▇▇▇▇ 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, within 120 days after the end of each fiscal year of the Company, 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 Indenture.

(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 certificates described in paragraph (b) above).

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, subject to the following sentence, 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.

ARTICLE V

CONSOLIDATION, MERGER, SALE, CONVEYANCE, TRANSFER OR LEASE

Sections 801 and 802 of the Base Indenture shall apply to the Notes, and the covenants therein shall be deemed included in the Indenture for the benefit of the Notes.

ARTICLE VI

DEFAULTS AND REMEDIES

Sections 501 and 502 of the Base Indenture shall not apply to the Notes, and shall be deemed not to be included in the Indenture for the benefit of the Notes.

Sections 6.1 and 6.2 below shall apply to the Notes and shall be deemed to be included in the Indenture solely for the benefit of the Notes:

SECTION 6.1. Events of Default.

(a) Each of the following is an “Event of Default” with respect to the Notes:

(1) default in any payment of interest on any Note when due and payable, continued for 30 days;

(2) default in the payment of principal of or premium, if any, on any Note when due and payable at its Stated Maturity, upon optional redemption, upon acceleration or otherwise;

(3) failure by the Company to comply for 180 days after notice as provided below with Section 4.2 of this Supplemental Indenture;

(4) failure by the Company to comply for 90 days after notice as provided below with its agreements (other than the agreements that are the subjects of clauses (1)-(3) above) contained in the Indenture (as it relates to the Notes) or the Notes;

(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:

(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, as applicable, aggregates to $250.0 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;

(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;

(7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

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

(B) appoints a Custodian for all or substantially all of the property of the Company, pursuant to or within the meaning of the Bankruptcy Law; or

in case of (A), (B) or (C), the order or decree remains unstayed or not dismissed and in effect for 60 days following the entry, issuance or effective date thereof; or

(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 (as it relates to the Notes) 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 applicable 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 in respect of the Notes 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 (x) such Indebtedness or guarantee is discharged in full (other than customary surviving contingent obligations) or (y) 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, in each case, within 60 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 as to the Notes, but before a judgment or decree for the payment of the money due has been obtained by the Trustee, 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 rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

ARTICLE VII

SATISFACTION AND DISCHARGE; DEFEASANCE

The satisfaction and discharge and Defeasance and Covenant Defeasance provisions in Articles IV and XIII of the Base Indenture shall be applicable to the Notes and any Guarantee thereof.

In the case of a Covenant Defeasance as to the Notes, (i) the Company will be released from its obligations to comply with Sections 4.1 and 4.2 of this Supplemental Indenture (for the benefit of Holders of Notes) and Section 1004 of the Base Indenture (for the benefit of Holders 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 in respect of the Notes or satisfies and discharges the Indenture with respect to the Notes, in each case all Guarantees in respect of the Notes (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 the Subsidiary Guarantee) and the Notes to:

(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 entity of the obligations of a Guarantor in accordance with the applicable provisions of the Indenture;

(5) secure the Notes or any Guarantee thereof;

(6) add covenants of the Company or other obligor under the Indenture (as it relates to the Notes) or the Notes or any Guarantee, as the case may be, or Events of Default for the benefit of the Holders of the Notes or any 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 (as it relates to the Notes) or the Notes;

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

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

(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 Subsidiary Guarantee to any provision of the section of the Company’s Prospectus Supplement dated March 6, 2025 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 (as it relates to the Notes or the Subsidiary Guarantee), the Notes or the Subsidiary Guarantee, which intent shall be established by an Officer’s 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 Subsidiary Guarantee) 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 Subsidiary Guarantee) 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.

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.

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 and the Notes) 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 with respect to the Notes, 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.

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 (as it relates to the Notes) and the Subsidiary 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 as to the Notes, upon the liquidation or dissolution of the Subsidiary Guarantor.
