The Notes are to be issued pursuant to an indenture, dated as of August 8, 2019 (the “Indenture,” which term, for purposes of this Agreement and each series of Notes herein, includes the applicable Officer’s Certificate with respect to such series of Notes delivered pursuant to Section 301 of the Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). BofA Securities, Inc., J.P. Morgan Securities LLC, MUFG Securities Americas Inc. and SMBC Nikko Securities America, Inc. will be the representatives of the several Underwriters (the “Representatives”).

The Company has filed with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3ASR (No. 333-266420) for the registration of debt securities, including the Notes, under the Securities Act of 1933, as amended (the “1933 Act”), and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Such registration statement became effective upon filing with the Commission pursuant to Rule 462(e) of the 1933 Act Regulations, and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “1939 Act”). Such registration statement (as amended by any subsequent post-effective amendments thereto) and the prospectus dated July 29, 2022 (the “Base Prospectus”), together with the final prospectus supplement dated July 23, 2024 (the “Final Prospectus Supplement”) relating to the Notes, including, in each case, all Incorporated Documents (as hereinafter defined) and, solely in the case of any such registration statement, the information that is deemed pursuant to Rule 430B of the 1933 Act Regulations to be part of such registration statement (“Rule 430B Information”), are referred to herein as the “Registration Statement” and the “Prospectus,” respectively, except that, if any revised prospectus or any revised or additional prospectus supplement filed by the Company is provided to the Underwriters by the Company for use in connection with the offering of the Notes (including for delivery upon request of purchasers of Notes pursuant to Rule 173 of the 1933 Act Regulations), the term “Prospectus” will refer to such revised prospectus or any such revised or additional prospectus supplement, as the case may be, from and after the time it is first provided to the Underwriters for such use. As used herein, the term “preliminary prospectus” means any prospectus supplement filed by the Company relating to the Notes that is captioned “Subject to Completion” or “preliminary prospectus supplement” or that has a similar caption, together with the Base Prospectus, including all Incorporated Documents, it being understood that all references herein to a “preliminary prospectus” include, without limitation, the Statutory Prospectus (as defined below). Any reference herein to the Registration Statement, any preliminary prospectus or the Prospectus is deemed to refer to and include the documents, financial statements and schedules incorporated, or deemed to be incorporated, by reference therein (other than information in  such documents, financial statements and schedules that is deemed not to be filed) pursuant to Item 12 of Form S-3ASR under the 1933 Act, and any reference to any amendment or supplement to the Registration Statement, any preliminary prospectus or the Prospectus is deemed to refer to and include any documents, financial statements and schedules filed by the Company with the Commission under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and so incorporated, or deemed to be incorporated, by reference (other than information in such documents, financial statements and schedules that is deemed not to be filed) (such incorporated documents, financial statements and schedules being herein called the “Incorporated Documents”). Notwithstanding the foregoing, for purposes of this Agreement, any prospectus supplement prepared or filed with respect to an offering pursuant to the Registration Statement of any securities other than the Notes will not be deemed to have supplemented any preliminary prospectus or the Prospectus and the information therein will not be deemed Rule 430B Information. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or any preliminary prospectus, or to any Issuer Free Writing Prospectus, Issuer General Use Free Writing Prospectus or Issuer Limited Use Free Writing Prospectus (as such terms are hereinafter defined) or to any amendment or supplement to any of the foregoing are deemed to include any copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

The Company intends to use the net proceeds of the offering of the Notes, together with the net proceeds of the Related Financing Transactions (as defined in the Final Prospectus Supplement) and cash on hand, to finance (i) the cash consideration for the acquisition contemplated by the Partnership Interest Purchase Agreement, dated as of December 10, 2023 (as it may be amended from time to time, the “Partnership Interest Purchase Agreement”), among CrownRock Holdings, L.P., a Delaware limited partnership, and CrownRock GP, LLC, a Delaware limited liability company, as sellers (the “Sellers”), Coral Holdings LP, LLC, a Delaware limited liability company, and Coral Holdings GP, LLC, a Delaware limited liability company, as purchasers (the “Purchasers”), and the Company, as parent. Subject to the terms and conditions of the Partnership Interest Purchase Agreement, the Purchasers will acquire 100% of the issued and outstanding partner interests of CrownRock, L.P., a Delaware limited partnership (“CrownRock”), from the Sellers (the “Acquisition”), (ii) the Refinancing Transactions (as defined in the Final Prospectus Supplement) and (iii) related fees and expenses. Upon completion of the Acquisition, CrownRock will be a wholly owned subsidiary of the Company.

(ii)           the transmittal to the Commission for filing of any supplement to any preliminary prospectus or the Prospectus (other than an amendment or supplement relating solely to an offering of securities other than the Notes) or any document to be filed pursuant to the 1934 Act which would be incorporated by reference in the Prospectus,

If any stop order is issued, the Company will use its reasonable best efforts to obtain the lifting thereof at the earliest possible moment.

(b)          Payment of Commission Fees.  The Company will pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1)(i) of the 1933 Act Regulations and otherwise in accordance with Rules 456(b) and 457(r) of the 1933 Act Regulations (including, if applicable, by updating the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or as an exhibit to a prospectus or prospectus supplement filed pursuant to Rule 424(b)).

(c)          Notice of Certain Proposed Filings. During the period in which a prospectus relating to the Notes is required to be delivered under the 1933 Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), the Company will:

(ii)          furnish the Underwriters with copies of any such amendment or supplement, and

(iii)          not file any such amendment or supplement of which the Underwriters have not previously been advised or to which the Representatives reasonably object in writing, unless, in the judgment of the Company and its counsel, such amendment or supplement is necessary to comply with law.

The Company will deliver to each of the Underwriters one signed and as many conformed copies of the Registration Statement (as originally filed) and of each amendment thereto relating to the Notes (including the Incorporated Documents and any exhibits filed therewith or incorporated by reference therein) as the Underwriters may reasonably request. So long as delivery of a prospectus by an Underwriter or dealer may be required by the 1933 Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), the Company will furnish to the Underwriters as many copies of the Prospectus (as amended or supplemented) and any Issuer Free Writing Prospectuses as the Underwriters reasonably request .

(e)          Revisions of Prospectus—Material Changes. During the period in which a prospectus relating to the Notes is required to be delivered under the 1933 Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172),

(i)          if (x) any event occurs or condition exists as a result of which it is necessary, in the opinion of counsel for the Company and of counsel for the Underwriters, to further amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not misleading, in the light of the circumstances existing at the time it is delivered to a purchaser, or (y) it is necessary, in the opinion of such counsel, to amend or supplement the Registration Statement or the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations:

(A)             prompt notice will be given, and confirmed in writing, to the Underwriters, and

(B)             the Company will promptly prepare and file an amendment or supplement to the Prospectus so that the Prospectus, as amended or supplemented, will (1) not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not misleading, in the light of the circumstances existing at the time it is delivered to the Underwriters, or (2) comply with the requirements of the 1933 Act or the 1933 Act Regulations, as applicable, or

(ii)          if at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which (x) such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement or the Prospectus or any preliminary prospectus or (y) when considered together with the General Disclosure Package, included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Underwriters and will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission and shall promptly provide such amended or supplemented Issuer Free Writing Prospectus to the Underwriters. Such notification from the Company to the Underwriters shall direct the Underwriters to suspend use of such Issuer Free Writing Prospectus until the Company shall have provided the Underwriters an amended or supplemented Issuer Free Writing Prospectus as contemplated above, in which case the Underwriters will cease using such Issuer Free Writing Prospectus until such time as the Company shall have provided them such amended or supplemented Issuer Free Writing Prospectus.

The foregoing covenants in this Section 4(e) do not apply to statements or omissions in the Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of the Underwriters through the Representatives expressly for use therein or in any Form T-1.

(f)          Earnings Statements. The Company will make generally available to its security holders a consolidated earnings statement (which need not be audited) covering a period of at least twelve months commencing after the Closing Time, as soon as is reasonably practicable after the end of such period, which earnings statement will satisfy the provisions of Section 11(a) of the 1933 Act (and at the option of the Company, Rule 158 of the 1933 Act Regulations).

(g)          Blue Sky Qualifications. The Company will endeavor, in cooperation with the Underwriters, to qualify the Notes for offering and sale under the applicable securities laws of such states and other jurisdictions as the Underwriters may reasonably designate (provided that no registration will be required in any jurisdiction outside the United States) and will maintain such qualifications in effect for as long as may be required for the distribution of the Notes; provided, however, that the Company will promptly notify the Underwriters of any suspension of any such qualifications; and provided, further, that the Company will not be obligated to register or qualify as a foreign corporation or take any action which would subject it to general service of process in any jurisdiction where it is not now so subject.

(h)          Filing of Prospectus; Preparation of Final Term Sheet. (i) The Company will prepare a final term sheet (the “Final Term Sheet”) reflecting the final terms of the Notes, which will be substantially in the form set forth in Schedule B but may also include credit ratings information with respect to the Notes, and will file such Final Term Sheet, in a form approved by the Representatives, as an “issuer free writing prospectus” pursuant to Rule 433 prior to the close of business within two business days after the date of this Agreement.

(ii)          The Company will prepare and file or transmit for filing with the Commission within the time period specified by Rule 424(b) of the 1933 Act Regulations (without reliance on Rule 424(b)(8)), the Prospectus containing the terms of the Notes and such other information as the Representatives and the Company deem appropriate.

(i)          Issuer Free Writing Prospectuses. (i) The Company represents and agrees that, unless it obtains the prior consent of the Representatives (which will not be unreasonably withheld or delayed), and (ii) each Underwriter, severally and not jointly, represents and agrees that, unless it obtains the prior written consent of the Company and the Representatives (which will not be unreasonably withheld or delayed), it has not made and will not make any offer relating to the Notes that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed by the Company with the Commission or retained by the Company pursuant to Rule 433; provided that the Company consents to the use by any Underwriter of a free writing prospectus that:

(ii)          is not an “issuer free writing prospectus” as defined in Rule 433, and

(iii)          contains only:

  (x)          information describing the preliminary terms of the Notes or their offering,

  (y)          information that describes the final terms of the Notes or their offering and that is included in the Final Term Sheet contemplated in Section 4(h) of this Agreement, or

 (z)           contains comparable bond price or similar information that (in the case of this clause (z) only) is not “issuer information,” as defined in Rule 433.

Any such free writing prospectus as to which consent has been given by the Representatives or by the Company and the Representatives, as the case may be, is referred to as a “Permitted Free Writing Prospectus.”  Without limiting the effect of the prior sentence, it is agreed that each of the Final Term Sheet and any Issuer Free Writing Prospectus listed on Schedule C is a Permitted Free Writing Prospectus.

The Company will pay all expenses incident to the performance of its obligations under this Agreement, including:

(f)          The printing and delivery to the Underwriters, in quantities as hereinabove stated, of copies of the Registration Statement and any amendments thereto and of the General Disclosure Package, each preliminary prospectus and the Prospectus and any amendments or supplements thereto relating to the Notes, and the delivery by the Underwriters of the General Disclosure Package, each preliminary prospectus and the Prospectus and any amendments or supplements thereto, in each case as they relate to the Notes or to sales or solicitations of offers to purchase the Notes during the period in which a prospectus relating to the Notes is required to be delivered under the 1933 Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172);

(g)          The preparation, printing and delivery to the Underwriters of copies of the Indenture; and

(h)          Any fees charged by rating agencies for the rating of the Notes.

If this Agreement is terminated pursuant to any of the provisions of this Agreement (otherwise than by notice given by the Underwriters in connection with the occurrence of any event set forth in clauses (ii) through (iv) of Section 10(a) or pursuant to Section 11), the Company will reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonable and documented fees and disbursements of counsel for the Underwriters, incurred in connection with this Agreement and the offering of the Notes contemplated hereby.

(i)          against any and all loss, liability, claim, damage and expense whatsoever (including, subject to the limitations set forth in subsection 7(c), the reasonable and documented fees and disbursements of counsel chosen by the Representatives), as incurred, insofar as such loss, liability, claim, damage or expense arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii)          against any and all loss, liability, claim, damage and expense whatsoever (including, subject to the limitations set forth in subsection 7(c), the reasonable and documented fees and disbursements of counsel chosen by the Representatives), as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever, insofar as such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company; and

(iii)       against any and all expense whatsoever (including, subject to the limitations set forth in subsection 7(c), the reasonable and documented fees and disbursements of counsel chosen by the Representatives), as incurred, reasonably incurred in investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever, based upon any such untrue statement or omission, or any such alleged untrue statement or omission;

provided, however, that this indemnity will not apply to any loss, liability, claim, damage or expense (A) to the extent arising out of or is based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon the Form T-1 under the 1939 Act filed as an exhibit to the Registration Statement; or (B) as to which such Underwriter may be required to indemnify the Company pursuant to the provisions of subsection (b) of this Section 7.

(b)          Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection 7(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, any preliminary prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representatives expressly for use in the Registration Statement, such preliminary prospectus, the General Disclosure Package, such Issuer Free Writing Prospectus or the Prospectus (or such amendment or supplement).

(c)          General. (i) In case any action, suit or proceeding (including any governmental or regulatory investigation or proceeding) is brought against any Underwriter, any officer or director of such Underwriter or any person controlling such Underwriter, based upon the Registration Statement, any preliminary prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) and with respect to which indemnity may be sought against the Company pursuant to this Section 7, such Underwriter, officer, director or controlling person will promptly notify the Company in writing, and the Company will assume the defense thereof, including the employment of counsel reasonably satisfactory to the Representatives and payment of all expenses. Failure to give such notice will not relieve the Company from any liability under this Section 7 to the extent it is not materially prejudiced as a result thereof and in any event will not relieve it from any liability which it may have otherwise than on account of the indemnity contained in this Section 7. Any such Underwriter, any such officer or director or any such controlling person will have the right to employ separate counsel in any such action, suit or proceeding and to participate in the defense thereof, but the fees and expenses of such separate counsel will be at the expense of such Underwriter, such officer or director or such controlling person, unless (A) the employment of such counsel has been specifically authorized in writing by the Company, (B) the Company has failed to assume the defense and employ reasonably satisfactory counsel or (C) the named parties to any such action, suit or proceeding (including any impleaded parties) include such Underwriter, such officer or director or such controlling person and the Company, and such Underwriter, such officer or director or such controlling person has been advised by such counsel that there may be one or more legal defenses available to it that are different from, or additional to, those available to the Company (in which case, if such Underwriter, such officer or director or such controlling person notifies the Company in writing that it elects to employ separate counsel at the expense of the Company, the Company will not have the right to assume the defense of such action, suit or proceeding on behalf of such Underwriter, such officer or director or such controlling person, it being understood, however, that the Company will not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to one separate firm of attorneys acting as local counsel in each relevant jurisdiction) for all such Underwriters, all such officers and directors and all such controlling persons, which firm will be designated in writing by the Representatives, on behalf of all of such Underwriters, all such officers and directors and such controlling persons). An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(ii)          In case any action, suit or proceeding (including any governmental or regulatory investigation or proceeding) is brought against the Company, any of the Company’s directors or officers, or any person controlling the Company, with respect to which indemnity may be sought against any Underwriter pursuant to this Section 7, such Underwriter will have the rights and duties given to the Company by subsection 7(c)(i) with respect thereto (provided that, notwithstanding the foregoing, any authorization of the nature specified in clause (A) of subsection Section 7(c)(i) may be given only by the Representatives and copies of all notices given by the Company, any such officer or director or any such controlling person of the nature specified in such subsection 7(c)(i) will also be sent to the Representatives), and the Company, such directors and officers and any such controlling persons will have the rights and duties given to the Underwriters by subsection 7(c)(i) with respect thereto, it being understood, however, that the Underwriters will not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to one separate firm of attorneys acting as local counsel in each relevant jurisdiction) for the Company, all such officers and directors and all such controlling persons, which firm will be designated in writing by the Company, on behalf of the Company, all such officers and directors and such controlling persons.

In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 7 is for any reason held to be unenforceable with respect to the indemnified parties, although applicable in accordance with its terms, the Company and the Underwriters will contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and the Underwriters, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages and expenses. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, will be deemed to be in the same proportions as the total net proceeds from the sale of the Notes (before deducting expenses) received by the Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, bear to the total price to public of the Notes as set forth in the table on the cover page of the Prospectus. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, will be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Notes set forth opposite their names in Schedule A, and not joint. Notwithstanding the provisions of this Section 8, no Underwriter will be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed by the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each officer and director of an Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act will have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act will have the same rights to contribution as the Company. Any party entitled to contribution hereunder will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 8, notify such party or parties from whom contribution may be sought (with, in the case of any notice given by the Company or any of its officers, directors or controlling persons, a copy to the Representatives), but the omission to so notify such party or parties will not relieve the party or parties from whom contribution may be sought from any obligation under this Section 8 to the extent it or they are not materially prejudiced as a result thereof and in any event will not relieve it or them from any other obligation it or they may have otherwise than under this Section 8.

All representations, warranties and agreements contained in this Agreement (including, without limitation, the provisions of Sections 7 and 8), or contained in certificates signed by any officer of the Company and delivered to the Underwriters, the Representatives or counsel for the Underwriters in connection with the transactions contemplated in this Agreement, will remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer or director of any Underwriter or any controlling person of any Underwriter, or by or on behalf of the Company, and will survive delivery of and payment for any of the Notes.

(a)          The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time if between the date of this Agreement and the Closing Time:

(i)            there has been any material adverse change in the consolidated financial condition of the Combined Company,

(ii)          there has occurred any material adverse change in the financial markets in the United States or any outbreak or escalation of hostilities or other national or international calamity or crisis, in each case set forth in this clause (ii) the effect of which, individually or in the aggregate, shall be such as to make it, in the reasonable judgment of the Representatives, impracticable to proceed with the offering, sale or delivery of the Notes or to enforce contracts for sale of the Notes,

(iii)          trading in any securities of the Company has been suspended by the Commission or a national securities exchange in the United States, or if trading generally on the New York Stock Exchange has been suspended or settlement has been materially disrupted, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by said exchange or by order of the Commission or any other governmental authority, or if a banking moratorium has been declared by either Federal or New York authorities, or

(iv)          any of S&P Global Ratings and Moody’s Investors Service, Inc. (or any of their respective successors) has publicly announced that it has (A) placed the Notes or the Company’s unsecured senior long term debt generally on what is commonly termed a “watch list” for possible downgrading or (B) downgraded the Notes or the Company’s unsecured senior long term debt generally.

(b)          If this Agreement is terminated pursuant to this Section, such termination will be without liability of any party to any other party except as provided in Section 5.

If one or more of the Underwriters fails at the Closing Time to purchase the Notes which it or they are obligated to purchase under this Agreement (the “Defaulted Notes”), the non-defaulting Underwriters will have the right, within 24 hours thereafter, to make arrangements for one or more of such non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; provided, however, that if such non-defaulting Underwriters have not completed such arrangements within such 24-hour period, then:

(a)          if the aggregate principal amount of Defaulted Notes does not exceed 10% of the aggregate principal amount of the Notes, the non-defaulting Underwriters will be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b)          if the aggregate principal amount of Defaulted Notes exceeds 10% of the aggregate principal amount of the Notes, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the acknowledgements and agreements in Section 2(c), the provisions of Section 5, and the indemnity and contribution agreements set forth in Sections 7 and 8 and the provisions of Section 15 will remain in effect.

No action pursuant to this Section will relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company will have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. The term “Underwriter” as used in this Agreement will include any underwriter substituted for a defaulting Underwriter.

 The Notes are redeemable, in whole or in part, at any time and from time to time, prior to July 1, 2027 (the “Par Call Date”), at the option of the Company at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes mature 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 15 basis points less (b) interest accrued to the Redemption Date and (ii) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

 On or after the Par Call Date, the Notes are redeemable, in whole or in part, at any time and from time to time at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

 Notwithstanding the foregoing, with respect to interest that is due and payable on any interest payment date falling on or prior to a Redemption Date for such Notes, the Company will pay such interest to the persons who were record holders of such Notes at the close of business on the relevant Regular Record Date.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

 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 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: (i) 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 (ii) 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 the Remaining Life 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 (iii) 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 equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date 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.

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

 Notice of any optional redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Notes to be redeemed, all as more fully provided in the Indenture. The Company may provide in any notice of optional redemption that payment of the Redemption Price and the performance of any obligations with respect to such redemption may be performed by another person; provided, however, that the Company will remain obligated to pay the Redemption Price and perform any such obligations with respect to such redemption in the event such other person fails to do so.

 In the case of a partial redemption of the Notes, for so long as the Notes are held by the Depositary (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary, and otherwise selection of the Notes for redemption will be made by lot. 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 optional 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.

 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

 For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the Company of this Note shall relate, in the case that this Note is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this Note that has been, or is to be, redeemed.

 If (i) the closing of the CrownRock Acquisition has not occurred on or prior to the later of (x) December 10, 2025 and (y) such date to which the outside date under the Purchase Agreement as in effect on July 26, 2024 may be extended in accordance with the terms thereof, any such extension to be set forth in an officer’s certificate delivered to the Trustee prior to the close of business on December 10, 2025 or such other extended outside date as shall then be applicable, (such later date, the “Special Mandatory Redemption Outside Date”), (ii) prior to the Special Mandatory Redemption Outside Date, the Purchase Agreement is terminated according to its terms without the closing of the CrownRock Acquisition, or (iii) the Company determines based on its reasonable judgment (in which case the Company will notify the Trustee in writing thereof) that the CrownRock Acquisition will not close prior to the Special Mandatory Redemption Outside Date or at all (any event in clause (i), (ii) or (iii), a “Special Mandatory Redemption Event”), the Company will be required to redeem all of the outstanding Notes at a Redemption Price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to but excluding the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”) (such redemption, a “Special Mandatory Redemption”).

 Upon the occurrence of a Special Mandatory Redemption Event, the Company will promptly (but in no event later than ten (10) Business Days following such Special Mandatory Redemption Event) cause notice to be delivered electronically or mailed to each holder of the Notes at its registered address (such date of notification to the holders, the “redemption notice date”). The notice will inform holders that the Notes will be redeemed on the fifth Business Day following the redemption notice date (the “Special Mandatory Redemption Date”) and that all of the outstanding Notes to be redeemed will be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the holders of the Notes. No later than 10:00 a.m., New York City time, on the Special Mandatory Redemption Date, the Company will deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price. If such deposit is made as provided above, the Notes to be redeemed will cease to bear interest on and after the Special Mandatory Redemption Date.

 Upon the completion of the CrownRock Acquisition, the foregoing provisions regarding Special Mandatory Redemption will cease to apply.

“CrownRock Acquisition” means the acquisition by the Purchasers of 100% of the issued and outstanding partnership interests of CrownRock, L.P., a Delaware limited partnership (“CrownRock”), from the Sellers pursuant to the Purchase Agreement.

“Purchase Agreement” means the Partnership Interest Purchase Agreement, dated as of December 10, 2023, by and among the Company, CrownRock Holdings, L.P., a Delaware limited partnership (“Limited Partner”), CrownRock GP, LLC, a Delaware limited liability company (“General Partner” and, together with the Limited Partner, the “Sellers”), Coral Holdings LP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“LP Purchaser”), and Coral Holdings GP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“GP Purchaser,” together with the LP Purchaser, the “Purchasers”), as amended, supplemented or otherwise modified from time to time.

 If an Event of Default with respect to the Notes shall occur and be continuing, the principal of and accrued interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

 The Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

 No reference herein to the Indenture and no provision of this Note, subject to the provisions for satisfaction and discharge in Article Four of the Indenture, shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

 The Indenture permits the Company, by irrevocably depositing cash or U.S. Government Obligations, in amounts and maturities sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be, the entire indebtedness on all Outstanding Notes with the Trustee in trust, solely for the benefit of the Holders of all Outstanding Notes, to defease the Indenture with respect to the Notes (subject to specified exceptions), and, upon such deposit and satisfaction of the other conditions set forth in the Indenture, the Company shall be deemed to have paid and discharged its entire indebtedness on the Notes.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Notes is registrable in the Security Register, upon surrender of a Note for registration of transfer at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

 No service charge shall be made by the Company, the Trustee or the Security Registrar for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than exchanges pursuant to Sections 304, 305, 906 or 1107 of the Indenture not involving any transfer).

 Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 This Note shall be governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws principles thereof).

 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within- mentioned Indenture.

[Signature Page to Trustee’s Certificate of Authentication – Note 2029 – R-   ]

 This Note is one of a duly authorized issue of securities (herein called the “Securities”) of the Company, issued and to be issued pursuant to the Indenture. This Note is one of a series designated by the Company as its 5.200% Senior Notes due 2029 (the “Notes”), limited in initial aggregate principal amount to $1,200,000,000. The Indenture does not limit the aggregate principal amount of the Securities.

 The Company issued this Note pursuant to an Indenture, dated as of August 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note, shall include the Officer’s Certificate dated as of July 26, 2024, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

 The Notes are issuable in denominations of $2,000 and any amount in excess thereof which is an integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be presented for registration of transfer.

 The Company may, from time to time, without notice to or the consent of the Holders of the Notes, reopen the Notes and issue additional Notes.

 The Notes are redeemable, in whole or in part, at any time and from time to time, prior to July 1, 2029 (the “Par Call Date”), at the option of the Company at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes mature 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 (ii) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

 On or after the Par Call Date, the Notes are redeemable, in whole or in part, at any time and from time to time at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

 Notwithstanding the foregoing, with respect to interest that is due and payable on any interest payment date falling on or prior to a Redemption Date for such Notes, the Company will pay such interest to the persons who were record holders of such Notes at the close of business on the relevant Regular Record Date.

 “Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

 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 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: (i) 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 (ii) 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 the Remaining Life 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 (iii) 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 equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date 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.

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

 Notice of any optional redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Notes to be redeemed, all as more fully provided in the Indenture. The Company may provide in any notice of optional redemption that payment of the Redemption Price and the performance of any obligations with respect to such redemption may be performed by another person; provided, however, that the Company will remain obligated to pay the Redemption Price and perform any such obligations with respect to such redemption in the event such other person fails to do so.

 In the case of a partial redemption of a the Notes, for so long as the Notes are held by the Depositary (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary, and otherwise selection of the Notes for redemption will be made by lot. 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 optional 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.

 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

 For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the Company of this Note shall relate, in the case that this Note is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this Note that has been, or is to be, redeemed.

 If (i) the closing of the CrownRock Acquisition has not occurred on or prior to the later of (x) December 10, 2025 and (y) such date to which the outside date under the Purchase Agreement as in effect on July 26, 2024 may be extended in accordance with the terms thereof, any such extension to be set forth in an officer’s certificate delivered to the Trustee prior to the close of business on December 10, 2025 or such other extended outside date as shall then be applicable, (such later date, the “Special Mandatory Redemption Outside Date”), (ii) prior to the Special Mandatory Redemption Outside Date, the Purchase Agreement is terminated according to its terms without the closing of the CrownRock Acquisition, or (iii) the Company determines based on its reasonable judgment (in which case the Company will notify the Trustee in writing thereof) that the CrownRock Acquisition will not close prior to the Special Mandatory Redemption Outside Date or at all (any event in clause (i), (ii) or (iii), a “Special Mandatory Redemption Event”), the Company will be required to redeem all of the outstanding Notes at a Redemption Price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to but excluding the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”) (such redemption, a “Special Mandatory Redemption”).

 Upon the occurrence of a Special Mandatory Redemption Event, the Company will promptly (but in no event later than ten (10) Business Days following such Special Mandatory Redemption Event) cause notice to be delivered electronically or mailed to each holder of the Notes at its registered address (such date of notification to the holders, the “redemption notice date”). The notice will inform holders that the Notes will be redeemed on the fifth Business Day following the redemption notice date (the “Special Mandatory Redemption Date”) and that all of the outstanding Notes to be redeemed will be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the holders of the Notes. No later than 10:00 a.m., New York City time, on the Special Mandatory Redemption Date, the Company will deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price. If such deposit is made as provided above, the Notes to be redeemed will cease to bear interest on and after the Special Mandatory Redemption Date.

 Upon the completion of the CrownRock Acquisition, the foregoing provisions regarding Special Mandatory Redemption will cease to apply.

 “CrownRock Acquisition” means the acquisition by the Purchasers of 100% of the issued and outstanding partnership interests of CrownRock, L.P., a Delaware limited partnership (“CrownRock”), from the Sellers pursuant to the Purchase Agreement.

 “Purchase Agreement” means the Partnership Interest Purchase Agreement, dated as of December 10, 2023, by and among the Company, CrownRock Holdings, L.P., a Delaware limited partnership (“Limited Partner”), CrownRock GP, LLC, a Delaware limited liability company (“General Partner” and, together with the Limited Partner, the “Sellers”), Coral Holdings LP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“LP Purchaser”), and Coral Holdings GP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“GP Purchaser,” together with the LP Purchaser, the “Purchasers”), as amended, supplemented or otherwise modified from time to time.

 If an Event of Default with respect to the Notes shall occur and be continuing, the principal of and accrued interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

 The Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within- mentioned Indenture.

[Signature Page to Trustee’s Certificate of Authentication – Note 2032 – R-   ]

 This Note is one of a duly authorized issue of securities (herein called the “Securities”) of the Company, issued and to be issued pursuant to the Indenture. This Note is one of a series designated by the Company as its 5.375% Senior Notes due 2032 (the “Notes”), limited in initial aggregate principal amount to $1,000,000,000. The Indenture does not limit the aggregate principal amount of the Securities.

 The Company issued this Note pursuant to an Indenture, dated as of August 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note, shall include the Officer’s Certificate dated as of July 26, 2024, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

 The Notes are issuable in denominations of $2,000 and any amount in excess thereof which is an integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be presented for registration of transfer.

 The Company may, from time to time, without notice to or the consent of the Holders of the Notes, reopen the Notes and issue additional Notes.

 The Notes are redeemable, in whole or in part, at any time and from time to time, prior to November 1, 2031 (the “Par Call Date”), at the option of the Company at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes mature 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 (ii) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

 On or after the Par Call Date, the Notes are redeemable, in whole or in part, at any time and from time to time at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

 Notwithstanding the foregoing, with respect to interest that is due and payable on any interest payment date falling on or prior to a Redemption Date for such Notes, the Company will pay such interest to the persons who were record holders of such Notes at the close of business on the relevant Regular Record Date.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

 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 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: (i) 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 (ii) 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 the Remaining Life 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 (iii) 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 equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date 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.

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

 Notice of any optional redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Notes to be redeemed, all as more fully provided in the Indenture. The Company may provide in any notice of optional redemption that payment of the Redemption Price and the performance of any obligations with respect to such redemption may be performed by another person; provided, however, that the Company will remain obligated to pay the Redemption Price and perform any such obligations with respect to such redemption in the event such other person fails to do so.

 In the case of a partial redemption of the Notes, for so long as the Notes are held by the Depositary (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary, and otherwise selection of the Notes for redemption will be made by lot. 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 optional 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.

 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

 For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the Company of this Note shall relate, in the case that this Note is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this Note that has been, or is to be, redeemed.

 If (i) the closing of the CrownRock Acquisition has not occurred on or prior to the later of (x) December 10, 2025 and (y) such date to which the outside date under the Purchase Agreement as in effect on July 26, 2024 may be extended in accordance with the terms thereof, any such extension to be set forth in an officer’s certificate delivered to the Trustee prior to the close of business on December 10, 2025 or such other extended outside date as shall then be applicable, (such later date, the “Special Mandatory Redemption Outside Date”), (ii) prior to the Special Mandatory Redemption Outside Date, the Purchase Agreement is terminated according to its terms without the closing of the CrownRock Acquisition, or (iii) the Company determines based on its reasonable judgment (in which case the Company will notify the Trustee in writing thereof) that the CrownRock Acquisition will not close prior to the Special Mandatory Redemption Outside Date or at all (any event in clause (i), (ii) or (iii), a “Special Mandatory Redemption Event”), the Company will be required to redeem all of the outstanding Notes at a Redemption Price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to but excluding the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”) (such redemption, a “Special Mandatory Redemption”).

 Upon the occurrence of a Special Mandatory Redemption Event, the Company will promptly (but in no event later than ten (10) Business Days following such Special Mandatory Redemption Event) cause notice to be delivered electronically or mailed to each holder of the Notes at its registered address (such date of notification to the holders, the “redemption notice date”). The notice will inform holders that the Notes will be redeemed on the fifth Business Day following the redemption notice date (the “Special Mandatory Redemption Date”) and that all of the outstanding Notes to be redeemed will be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the holders of the Notes. No later than 10:00 a.m., New York City time, on the Special Mandatory Redemption Date, the Company will deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price. If such deposit is made as provided above, the Notes to be redeemed will cease to bear interest on and after the Special Mandatory Redemption Date.

 Upon the completion of the CrownRock Acquisition, the foregoing provisions regarding Special Mandatory Redemption will cease to apply.

 “CrownRock Acquisition” means the acquisition by the Purchasers of 100% of the issued and outstanding partnership interests of CrownRock, L.P., a Delaware limited partnership (“CrownRock”), from the Sellers pursuant to the Purchase Agreement.

 “Purchase Agreement” means the Partnership Interest Purchase Agreement, dated as of December 10, 2023, by and among the Company, CrownRock Holdings, L.P., a Delaware limited partnership (“Limited Partner”), CrownRock GP, LLC, a Delaware limited liability company (“General Partner” and, together with the Limited Partner, the “Sellers”), Coral Holdings LP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“LP Purchaser”), and Coral Holdings GP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“GP Purchaser,” together with the LP Purchaser, the “Purchasers”), as amended, supplemented or otherwise modified from time to time.

 If an Event of Default with respect to the Notes shall occur and be continuing, the principal of and accrued interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

 The Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

 No reference herein to the Indenture and no provision of this Note, subject to the provisions for satisfaction and discharge in Article Four of the Indenture, shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

 The Indenture permits the Company, by irrevocably depositing cash or U.S. Government Obligations, in amounts and maturities sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be, the entire indebtedness on all Outstanding Notes with the Trustee in trust, solely for the benefit of the Holders of all Outstanding Notes, to defease the Indenture with respect to the Notes (subject to specified exceptions), and, upon such deposit and satisfaction of the other conditions set forth in the Indenture, the Company shall be deemed to have paid and discharged its entire indebtedness on the Notes.

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Notes is registrable in the Security Register, upon surrender of a Note for registration of transfer at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

 No service charge shall be made by the Company, the Trustee or the Security Registrar for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than exchanges pursuant to Sections 304, 305, 906 or 1107 of the Indenture not involving any transfer).

 Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 This Note shall be governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws principles thereof).

 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

 All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within- mentioned Indenture.

[Signature Page to Trustee’s Certificate of Authentication – Note 2034 – R-   ]

This Note is one of a duly authorized issue of securities (herein called the “Securities”) of the Company, issued and to be issued pursuant to the Indenture. This Note is one of a series designated by the Company as its 5.550% Senior Notes due 2034 (the “Notes”), limited in initial aggregate principal amount to $1,200,000,000. The Indenture does not limit the aggregate principal amount of the Securities.

The Company issued this Note pursuant to an Indenture, dated as of August 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note, shall include the Officer’s Certificate dated as of July 26, 2024, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

The Notes are issuable in denominations of $2,000 and any amount in excess thereof which is an integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be presented for registration of transfer.

The Company may, from time to time, without notice to or the consent of the Holders of the Notes, reopen the Notes and issue additional Notes.

The Notes are redeemable, in whole or in part, at any time and from time to time, prior to July 1, 2034 (the “Par Call Date”), at the option of the Company at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes mature 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 25 basis points less (b) interest accrued to the Redemption Date and (ii) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Notes are redeemable, in whole or in part, at any time and from time to time at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

Notwithstanding the foregoing, with respect to interest that is due and payable on any interest payment date falling on or prior to a Redemption Date for such Notes, the Company will pay such interest to the persons who were record holders of such Notes at the close of business on the relevant Regular Record Date.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

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 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: (i) 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 (ii) 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 the Remaining Life 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 (iii) 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 equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date 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.

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

 Notice of any optional redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Notes to be redeemed, all as more fully provided in the Indenture. The Company may provide in any notice of optional redemption that payment of the Redemption Price and the performance of any obligations with respect to such redemption may be performed by another person; provided, however, that the Company will remain obligated to pay the Redemption Price and perform any such obligations with respect to such redemption in the event such other person fails to do so.

 In the case of a partial redemption of the Notes, for so long as the Notes are held by the Depositary (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary, and otherwise selection of the Notes for redemption will be made by lot. 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 optional 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.

 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

 For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the Company of this Note shall relate, in the case that this Note is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this Note that has been, or is to be, redeemed.

 If (i) the closing of the CrownRock Acquisition has not occurred on or prior to the later of (x) December 10, 2025 and (y) such date to which the outside date under the Purchase Agreement as in effect on July 26, 2024 may be extended in accordance with the terms thereof, any such extension to be set forth in an officer’s certificate delivered to the Trustee prior to the close of business on December 10, 2025 or such other extended outside date as shall then be applicable, (such later date, the “Special Mandatory Redemption Outside Date”), (ii) prior to the Special Mandatory Redemption Outside Date, the Purchase Agreement is terminated according to its terms without the closing of the CrownRock Acquisition, or (iii) the Company determines based on its reasonable judgment (in which case the Company will notify the Trustee in writing thereof) that the CrownRock Acquisition will not close prior to the Special Mandatory Redemption Outside Date or at all (any event in clause (i), (ii) or (iii), a “Special Mandatory Redemption Event”), the Company will be required to redeem all of the outstanding Notes at a Redemption Price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to but excluding the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”) (such redemption, a “Special Mandatory Redemption”).

 Upon the occurrence of a Special Mandatory Redemption Event, the Company will promptly (but in no event later than ten (10) Business Days following such Special Mandatory Redemption Event) cause notice to be delivered electronically or mailed to each holder of the Notes at its registered address (such date of notification to the holders, the “redemption notice date”). The notice will inform holders that the Notes will be redeemed on the fifth Business Day following the redemption notice date (the “Special Mandatory Redemption Date”) and that all of the outstanding Notes to be redeemed will be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the holders of the Notes. No later than 10:00 a.m., New York City time, on the Special Mandatory Redemption Date, the Company will deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price. If such deposit is made as provided above, the Notes to be redeemed will cease to bear interest on and after the Special Mandatory Redemption Date.

Upon the completion of the CrownRock Acquisition, the foregoing provisions regarding Special Mandatory Redemption will cease to apply.

“CrownRock Acquisition” means the acquisition by the Purchasers of 100% of the issued and outstanding partnership interests of CrownRock, L.P., a Delaware limited partnership (“CrownRock”), from the Sellers pursuant to the Purchase Agreement.

“Purchase Agreement” means the Partnership Interest Purchase Agreement, dated as of December 10, 2023, by and among the Company, CrownRock Holdings, L.P., a Delaware limited partnership (“Limited Partner”), CrownRock GP, LLC, a Delaware limited liability company (“General Partner” and, together with the Limited Partner, the “Sellers”), Coral Holdings LP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“LP Purchaser”), and Coral Holdings GP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“GP Purchaser,” together with the LP Purchaser, the “Purchasers”), as amended, supplemented or otherwise modified from time to time.

 If an Event of Default with respect to the Notes shall occur and be continuing, the principal of and accrued interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

 The Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note, subject to the provisions for satisfaction and discharge in Article Four of the Indenture, shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

The Indenture permits the Company, by irrevocably depositing cash or U.S. Government Obligations, in amounts and maturities sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be, the entire indebtedness on all Outstanding Notes with the Trustee in trust, solely for the benefit of the Holders of all Outstanding Notes, to defease the Indenture with respect to the Notes (subject to specified exceptions), and, upon such deposit and satisfaction of the other conditions set forth in the Indenture, the Company shall be deemed to have paid and discharged its entire indebtedness on the Notes.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Notes is registrable in the Security Register, upon surrender of a Note for registration of transfer at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

 No service charge shall be made by the Company, the Trustee or the Security Registrar for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than exchanges pursuant to Sections 304, 305, 906 or 1107 of the Indenture not involving any transfer).

 Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 This Note shall be governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws principles thereof).

 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

6.050% SENIOR NOTE DUE 2054

OCCIDENTAL PETROLEUM CORPORATION, a corporation duly organized and existing under the laws of the State of Delaware (herein referred to as the “Company,” which term includes any successor under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the lesser of (i) the Principal Amount specified above and (ii) the Principal Amount set forth on the Schedule of Exchanges of Interests in the Global Note attached hereto on the Maturity Date specified above (unless and to the extent earlier redeemed prior to such Maturity Date) and to pay interest thereon from July 26, 2024 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on April 1 and October 1 in each year, commencing on April 1, 2025, at the rate per annum specified above, until the principal hereof is paid or made available for payment. Interest on this Note will be computed on the basis of a 360-day year comprised of twelve 30-day months. Interest payments for this Note will include interest accrued to but excluding each Interest Payment Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall be the March 15 and September 15 (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. If any Interest Payment Date or Maturity with respect to this Note falls on a day that is not a Business Day, the payment due on such Interest Payment Date or Maturity will be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date or Maturity, and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or Maturity, as the case may be, until such following Business Day. Except as otherwise provided in the Indenture, any Defaulted Interest will forthwith cease to be payable to the Holder on the Regular Record Date with respect to such Interest Payment Date by virtue of having been such Holder and may either (1) be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee (as defined below), notice of which will be given to Holders of Notes not less than 10 days prior to such Special Record Date, or (2) be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Payment of the principal of and interest on this Note will be made at the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York, or at the office or agency of the Trustee maintained for that purpose in the Borough of Manhattan, The City of New York, or at any other office or agency designated by the Company for such purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided that, at the option of the Company, payment of interest due on any Interest Payment Date may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer of immediately available funds if appropriate wire transfer instructions have been received in writing by the Trustee not less than 15 days prior to the applicable Interest Payment Date.

Reference is hereby made to the further provisions of this Note set forth below, which further provisions shall for all purposes have the same effect as if set forth at this place.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

 This is one of the Securities of the series designated therein referred to in the within- mentioned Indenture.

[Signature Page to Trustee’s Certificate of Authentication – Note 2054 – R-   ]

 This Note is one of a duly authorized issue of securities (herein called the “Securities”) of the Company, issued and to be issued pursuant to the Indenture. This Note is one of a series designated by the Company as its 6.050% Senior Notes due 2054 (the “Notes”), limited in initial aggregate principal amount to $1,000,000,000 The Indenture does not limit the aggregate principal amount of the Securities.

 The Company issued this Note pursuant to an Indenture, dated as of August 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note, shall include the Officer’s Certificate dated as of July 26, 2024, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

 The Notes are issuable in denominations of $2,000 and any amount in excess thereof which is an integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be presented for registration of transfer.

The Company may, from time to time, without notice to or the consent of the Holders of the Notes, reopen the Notes and issue additional Notes.

 The Notes are redeemable, in whole or in part, at any time and from time to time, prior to April 1, 2054 (the “Par Call Date”), at the option of the Company at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes mature 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 25 basis points less (b) interest accrued to the Redemption Date and (ii) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

 On or after the Par Call Date, the Notes are redeemable, in whole or in part, at any time and from time to time at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

 Notwithstanding the foregoing, with respect to interest that is due and payable on any interest payment date falling on or prior to a Redemption Date for such Notes, the Company will pay such interest to the persons who were record holders of such Notes at the close of business on the relevant Regular Record Date.

 “Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

 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 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: (i) 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 (ii) 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 the Remaining Life 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 (iii) 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 equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date 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.

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

 Notice of any optional redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Notes to be redeemed, all as more fully provided in the Indenture. The Company may provide in any notice of optional redemption that payment of the Redemption Price and the performance of any obligations with respect to such redemption may be performed by another person; provided, however, that the Company will remain obligated to pay the Redemption Price and perform any such obligations with respect to such redemption in the event such other person fails to do so.

 In the case of a partial redemption of the Notes, for so long as the Notes are held by the Depositary (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary, and otherwise selection of the Notes for redemption will be made by lot. 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 optional 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.

 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

 For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the Company of this Note shall relate, in the case that this Note is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this Note that has been, or is to be, redeemed.

 If (i) the closing of the CrownRock Acquisition has not occurred on or prior to the later of (x) December 10, 2025 and (y) such date to which the outside date under the Purchase Agreement as in effect on July 26, 2024 may be extended in accordance with the terms thereof, any such extension to be set forth in an officer’s certificate delivered to the Trustee prior to the close of business on December 10, 2025 or such other extended outside date as shall then be applicable, (such later date, the “Special Mandatory Redemption Outside Date”), (ii) prior to the Special Mandatory Redemption Outside Date, the Purchase Agreement is terminated according to its terms without the closing of the CrownRock Acquisition, or (iii) the Company determines based on its reasonable judgment (in which case the Company will notify the Trustee in writing thereof) that the CrownRock Acquisition will not close prior to the Special Mandatory Redemption Outside Date or at all (any event in clause (i), (ii) or (iii), a “Special Mandatory Redemption Event”), the Company will be required to redeem all of the outstanding Notes at a redemption price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to but excluding the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”) (such redemption, a “Special Mandatory Redemption”).

 Upon the occurrence of a Special Mandatory Redemption Event, the Company will promptly (but in no event later than ten (10) Business Days following such Special Mandatory Redemption Event) cause notice to be delivered electronically or mailed to each holder of the Notes at its registered address (such date of notification to the holders, the “redemption notice date”). The notice will inform holders that the Notes will be redeemed on the fifth Business Day following the redemption notice date (the “Special Mandatory Redemption Date”) and that all of the outstanding Notes to be redeemed will be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the holders of the Notes. No later than 10:00 a.m., New York City time, on the Special Mandatory Redemption Date, the Company will deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price. If such deposit is made as provided above, the Notes to be redeemed will cease to bear interest on and after the Special Mandatory Redemption Date.

 Upon the completion of the CrownRock Acquisition, the foregoing provisions regarding Special Mandatory Redemption will cease to apply.

“CrownRock Acquisition” means the acquisition by the Purchasers of 100% of the issued and outstanding partnership interests of CrownRock, L.P., a Delaware limited partnership (“CrownRock”), from the Sellers pursuant to the Purchase Agreement.

 “Purchase Agreement” means the Partnership Interest Purchase Agreement, dated as of December 10, 2023, by and among the Company, CrownRock Holdings, L.P., a Delaware limited partnership (“Limited Partner”), CrownRock GP, LLC, a Delaware limited liability company (“General Partner” and, together with the Limited Partner, the “Sellers”), Coral Holdings LP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“LP Purchaser”), and Coral Holdings GP, LLC, a Delaware limited liability company and our wholly owned indirect subsidiary (“GP Purchaser,” together with the LP Purchaser, the “Purchasers”), as amended, supplemented or otherwise modified from time to time.

 If an Event of Default with respect to the Notes shall occur and be continuing, the principal of and accrued interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

 The Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

 No reference herein to the Indenture and no provision of this Note, subject to the provisions for satisfaction and discharge in Article Four of the Indenture, shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

 The Indenture permits the Company, by irrevocably depositing cash or U.S. Government Obligations, in amounts and maturities sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be, the entire indebtedness on all Outstanding Notes with the Trustee in trust, solely for the benefit of the Holders of all Outstanding Notes, to defease the Indenture with respect to the Notes (subject to specified exceptions), and, upon such deposit and satisfaction of the other conditions set forth in the Indenture, the Company shall be deemed to have paid and discharged its entire indebtedness on the Notes.

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Notes is registrable in the Security Register, upon surrender of a Note for registration of transfer at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

 No service charge shall be made by the Company, the Trustee or the Security Registrar for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than exchanges pursuant to Sections 304, 305, 906 or 1107 of the Indenture not involving any transfer).

 Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 This Note shall be governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws principles thereof).

In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including the Indenture (and the forms of Notes contained therein) and the Registration Statement on Form S‑3 (Registration No. 333‑266420) filed with the Securities and Exchange Commission (the “Commission”) on July 29, 2022 (the “Registration Statement”), with respect to registration under the Securities Act of 1933, as amended (the “Securities Act”) of an unlimited aggregate amount of various securities of the Company, to be issued from time to time by the Company.

In rendering this opinion, we have assumed, with your consent and without independent investigation or verification, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as duplicates or copies.  We also have assumed, with your consent, that the Indenture has been duly authorized, executed and delivered by, and represents a legal, valid and binding obligation of, the Trustee and that the Notes will conform to the respective forms thereof included in the Indenture.

Based on the foregoing and subject to the qualifications set forth herein, we are of opinion that when the Notes are authenticated in accordance with the provisions of the Indenture and delivered and paid for, they will constitute valid and binding obligations of the Company (subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and other similar laws affecting creditors’ rights generally from time to time in effect and to general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether considered in a proceeding in equity or at law).

We are admitted to practice in the State of New York, and we express no opinion as to matters governed by any laws other than the laws of the State of New York, the General Corporate Law of the State of Delaware and the Federal laws of the United States of America.

We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Current Report on Form 8-K dated the date hereof and incorporated by reference into the Registration Statement.  We also consent to the reference to our firm under the caption “Legal Matters” in the Prospectus Supplement dated July 23, 2024, constituting part of the Registration Statement.  In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
