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 2024 Notes (which shall be initially in the aggregate principal amount of $1,000,000,000), the 2026 Notes (which shall be initially in the aggregate principal amount of $800,000,000) and the 2029 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.

SECTION 1.3.    Form, Dating and Terms.

(a)    General. The aggregate principal amount of each Series of 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 (i) in the case of 2024 Notes, limited to $1,000,000,000, (ii) in the case of 2026 Notes, limited to $800,000,000 and (iii) in the case of 2029 Notes, limited to $1,200,000,000 (in each case, 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), 4.2(c) and 8.6 of this Supplemental Indenture and Sections 304, 305, 306 and 1107 of the Base Indenture).

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

Additional Notes of a Series 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 of such Series 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 of each Series shall be initially issued in the form of one or more permanent Global Securities substantially in the form of Exhibit A, Exhibit B or Exhibit C, as applicable (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.

Any of 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 for each Series attached as Exhibit A, Exhibit B and Exhibit C hereto, as applicable, 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 in the Borough of Manhattan, The City of New York. 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 of any Series 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.

(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

(c)    Definitive Notes. Except as provided in the Indenture, owners of beneficial interests in Global Notes shall not be entitled to receive Definitive Notes.

The Paying Agent will promptly send to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail or deliver (or cause to be transferred by book entry) to each Holder a new Note of like Series equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Paying Agent will deliver the Change of Control Payment for Global Notes in immediately available funds to the Depositary or its nominee, as the case may be, as the registered Holder of such Global Note.

The Change of Control provisions described in this Section 4.2 will be applicable whether or not any other provisions of the Indenture are applicable.

Notwithstanding anything to the contrary contained in the Indenture, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditioned upon the occurrence of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

(e)    In addition to (and not in limitation of) the rights of the Company in Section 3.1 of this Supplemental Indenture, in the event that Holders of not less than 90% in aggregate principal amount of the Outstanding Notes of a Series accept a Change of Control Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company pursuant to Section 4.2(d) of this Supplemental Indenture) purchases all of the Notes of such Series held by such Holders, the Company will have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer, to redeem all of the Notes of that Series that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes of that Series that remain outstanding, to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

(f)    The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 4.2.

(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 as to any Series until the Trustee or the Holders of at least 25% in principal amount of the then Outstanding Notes of such Series 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 as to any Series, the Trustee by written notice to the Company, or Holders of at least 25% in principal amount of the then outstanding Notes of such Series 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 of such Series shall, declare the principal, premium, if any, and accrued and unpaid interest, if any, on all the Notes of such Series 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 of any Series because an Event of Default described in Section 6.1(a)(5) has occurred and is continuing, the declaration of acceleration of the Notes of such Series 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 of such Series with respect thereto is received by the Company and if (1) the annulment of the acceleration of the Notes of such Series 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 of such Series that became due solely because of the acceleration of such Notes, have been cured or waived.

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

of such Series that have become due solely by such declaration of acceleration, have been cured or waived.

In the case of a Covenant Defeasance as to any Series, (i) the Company will be released from its obligations to comply with Sections 4.1, 4.2 and 4.3 of this Supplemental Indenture (for the benefit of Holders of Notes of such Series) and Section 1004 of the Base Indenture (for the benefit of Holders of Notes of such Series) 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 of such Series.

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

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.

(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 of such Series) or the Notes of such Series;

After an amendment, supplement or waiver under the Indenture becomes effective, the Company is required to send to the applicable 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 (as it relates to the Notes of any Series), the Base Indenture (as it relates to the Notes of such Series) and the Notes of such Series with the consent of the Holders of a majority in principal amount of the Notes of such Series 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 of such Series) and any past default or compliance with any provisions of this Supplemental Indenture (as it relates to the Notes of any Series), the Base Indenture (as it relates to the Notes of such Series) and the Notes of such Series may be waived with the consent of the Holders of a majority in principal amount of the Notes of such Series 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 of such Series).

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 of any Series 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 of any Series affected, no amendment, supplement or waiver may (with respect to any Notes of such Series held by a non-consenting Holder):

(1)    reduce the principal amount of Notes of such Series 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 of such Series;

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

(4)    waive a Default or Event of Default in the payment of principal of, premium, if any, or interest on the Notes of such Series (except a rescission of acceleration of the Notes of such Series by Holders of a majority in aggregate principal amount of the then outstanding Notes of such Series 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 or repurchase of any Note of such Series or change the time at which any Note of such Series may be redeemed or repurchased as described under Section 4.2 or Article III, whether through an amendment or waiver of Section 4.2, Article III, related definitions or otherwise (except amendments to the definitions of “Change of Control,” “Change of Control Triggering Event” or “Trigger Period”);

(6)    make any Note of such Series 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 of such Series 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 of such Series in any manner adverse to the Holders of the Notes of such Series; or

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

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 a Series of Notes once effective shall bind every Holder of Notes of such Series 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 a Series of Notes or the Base Indenture (as it relates to the Notes of such Series). If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders of Notes of such Series 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 of such Series 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 every Holder of Notes of the applicable Series theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

Article XIV of the Base Indenture shall apply to each Series of the Notes, except as described in this Article IX. The Notes of any Series will be fully and unconditionally Guaranteed (such guarantee, with respect to such Series, the “Subsidiary Guarantee”) by Diamondback O&G LLC (such entity during the period (and only during such period) that the Subsidiary Guarantee is in

effect as to such Series, with respect to such Series, 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 and its Guarantee with respect to a Series of Notes, and will cease to be a Guarantor with respect to such 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 such Series or satisfaction and discharge of such Series of 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 such Series, upon the liquidation or dissolution of the Subsidiary Guarantor.

In the event the Subsidiary Guarantor as to any Series 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 as to the Notes of such Series and will cease to be the Subsidiary Guarantor as to the Notes of such Series, 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 as to any Series from its obligations under the Subsidiary Guarantee and the Indenture as to the Notes of such Series.

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

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

Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Supplemental Indenture. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original instrument for all purposes. Signature pages of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

SECTION 10.4.    Paying Agent and Security Registrar. The Company initially appoints the Trustee as Paying Agent and Security Registrar with respect to any Global Notes.

SECTION 10.6.    Trust Indenture Act Controls. If any provision of the Indenture (as it relates to the Notes of any Series) limits, qualifies, or conflicts with another provision that is required or deemed to be included in the Indenture by the Trust Indenture Act, such required or deemed provision shall control. If any provision of the Indenture (as it relates to the Notes of any Series) modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the provision of the Trust Indenture Act shall be deemed to apply to the Indenture (as it relates to such Notes) as so modified or shall be excluded, as the case may be.

SECTION 10.7.    Table of Contents; Headings. The table of contents, cross-reference sheet and headings of the Articles and Sections of this Supplemental Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

Any such indenture, loan or debt agreement (including the Indenture (including any other supplemental indenture thereto) insofar as relating to any Series of Securities other than the Notes of any Series) may not be used to interpret the Indenture insofar as relating to the Notes of such Series.
