Ladies and Gentlemen:

Concho Resources Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), $500,000,000 aggregate principal amount of its 2.400% Senior Notes due 2031 (the “Notes”). The Notes will be guaranteed (the “Guarantees”) on an unsecured senior basis by each of the guarantors listed in Schedule 2 hereto (the “Guarantors”). The Securities (as defined below) will be issued pursuant to an Indenture dated as of September 18, 2009 (the “Base Indenture”), among the Company, the Guarantors party thereto and ▇▇▇▇▇ Fargo Bank, National Association, as trustee (the “Trustee”), as amended and supplemented by the Seventeenth Supplemental Indenture, to be dated as of August 24, 2020 (the “Supplemental Indenture”), among the Company, the Guarantors and the Trustee. The Base Indenture, as so amended and supplemented by the Supplemental Indenture is herein called the “Indenture,” and the Notes and the related Guarantees are herein collectively referred to as the “Securities.”

Each of the Company and the Guarantors hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), an automatic shelf registration statement on Form S-3 (File No. 333-225609), including a

prospectus, relating to the Securities. Such registration statement, including any post-effective amendments thereto and the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means the prospectus dated June 14, 2018 included in such registration statement that omits Rule 430 Information and the preliminary prospectus supplement filed with the Commission pursuant to Rule 424(b) under the Securities Act on August 10, 2020, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the time when sales of the Securities were first made (the “Time of Sale”), the Company had prepared the following information: the Preliminary Prospectus and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act), if any, listed on Annex B hereto (collectively, the “Time of Sale Information”).

2. Purchase of the Securities by the Underwriters. (a) The Company agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 99.111% of the principal amount of the Notes, plus accrued interest, if any, from August 24, 2020 to the Closing Date (as defined below). The Company will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

The time and date of such payment and delivery is referred to herein as the “Closing Date.”

(e) The Company and the Guarantors acknowledge and agree that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Guarantors with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Guarantors or any other person. Additionally, none of the Representatives or any other Underwriter is advising the Company, the Guarantors or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction.

(f) Ongoing Compliance. If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to Section 4(c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law.

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Company and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Underwriter, its affiliates, directors, officers and employees and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in

light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of the Company and the Guarantors. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Guarantors, each of their respective directors, their respective officers who signed the Registration Statement and each person, if any, who controls the Company or any of the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following: the information contained in the Prospectus in the first paragraph under the caption “Underwriting—Discounts” and the third and fourth sentences in the first paragraph under the caption “Underwriting—New Issue of Notes.”

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the

Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, the Guarantors, their respective directors, their respective officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other shall 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 any Guarantor or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in Section 7(d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or

agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and each of the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s and the Guarantors’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the

preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable fees and expenses of counsel for the Underwriters); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority, Inc.; and (ix) all expenses incurred by the Company in connection with any road show presentation to potential investors; provided that notwithstanding clause (ix) above, the Underwriters shall pay one-half of the lease expenses associated with any airplane which is used for the purposes of such road show presentations.

(b) If (i) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (ii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement (other than Section 9, but excluding any termination of this Agreement by the Representatives pursuant to clause (ii) thereof), the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Guarantors and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms.

15. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(1) The Company is a validly existing corporation in good standing under the laws of the State of Delaware.

(2) Each Guarantor is a validly existing corporation, limited liability company or limited partnership in good standing under the laws of its jurisdiction of formation as set forth opposite its name on Annex A hereto.

(3) The Company and each Guarantor has all requisite corporate, limited liability company or limited partnership power to execute and deliver the Note Documents to which it is a party and to perform its obligations thereunder.

(4) The execution and delivery by the Company and each Guarantor of the Note Documents to which it is a party and the performance of its obligations thereunder have been duly authorized by all necessary corporate, limited liability company or limited partnership action. Each of the Note Documents (other than the Notes and the Guarantees) has been duly executed and delivered by the Company and each Guarantor party thereto.

(5) The Indenture has been duly qualified under the Trust Indenture Act and constitutes a legal, valid and binding obligation of the Company and each Guarantor party thereto, enforceable against the Company and each such Guarantor in accordance with its terms.

(6) The Notes, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, will be legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

(7) When the Notes and the Guarantees endorsed thereon have been duly executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, the Guarantee of each Guarantor will be a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms.

(8) The execution and delivery by the Company and the Guarantors of the Note Documents to which it is a party, the performance of its obligations thereunder, and the issuance by the Company and the Guarantors of the Securities to the Underwriters:

(i) do not and will not violate the charter or bylaws or other constitutive documents of the Company or any of the Guarantors;

(ii) do not and will not (A) based solely upon review of such agreements, result in a breach of or default under or (B) result in or require the creation or imposition of any lien or encumbrance upon any assets of such Obligor under, any agreement to which the Company or any Guarantor is a party that is identified to us in a certificate of the Company as being material to the Company and its subsidiaries taken as a whole, each of which agreements are listed on Annex B hereto;

A-1-1

(iii) based solely upon review of such orders, judgments or decrees, do not and will not violate any order, judgment or decree of any court or other agency of government identified to us in a certificate of the Company as constituting all orders, judgments or decrees that are material to the Company and its subsidiaries taken as a whole and that are binding on the Company or any of the Guarantors, each of which orders, judgments and decrees is listed on Annex C hereto; and

(iv) do not and will not (A) violate, or require any filing with or approval of any governmental authority or regulatory body of the State of New York, the State of Texas or the United States of America under, any law, rule or regulation of the State of New York, the State of Texas or the United States of America applicable to the Company or any of the Guarantors that, in our experience, is generally applicable to transactions in the nature of those contemplated by the Underwriting Agreement, (B) violate, or require any filing with or approval of any governmental authority or regulatory body of the State of Delaware under, the Delaware General Corporation Law or the Delaware Limited Liability Company Act, or (C) require any filing with or approval of any governmental authority or regulatory body of the United States of America under the Securities Act of 1933, as amended (the “Securities Act”), or the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), except for such filings or approvals as already have been made or obtained.

(9) The Company is not and, after giving effect to the sale of the Securities and the use of proceeds therefrom as described in the Prospectus, will not be an “investment company” that is required to be registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”). For purposes of this paragraph 9, the term “investment company” has the meanings ascribed to such term in the Investment Company Act.

(10) Insofar as the statements in the General Disclosure Package and the Prospectus under the captions “Description of Notes” and “Description of Debt Securities” purport to describe specific provisions of the Notes or the Indenture, such statements present in all material respects an accurate summary of such provisions.

(11) To the extent that the statements in the General Disclosure Package and the Prospectus under the caption “Certain U.S. Federal Income Tax Considerations,” purport to describe specific provisions of the Internal Revenue Code of 1986, as amended, or the rules and regulations thereunder, such statements present in all material respects an accurate summary of such provisions.

Form of Disclosure Letter of ▇▇▇▇▇▇, ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP

Based on the designation of the Registration Statement as Form S-3ASR on the Commission’s ▇▇▇▇▇ website, we are of the view that the Registration Statement has become effective under the Securities Act. To our knowledge, based solely upon our review of the list of stop orders contained on the Commission’s website at ▇▇▇▇://▇▇▇.▇▇▇.▇▇▇/▇▇▇▇▇▇▇▇▇▇/▇▇▇▇▇▇▇▇▇▇.▇▇▇▇▇ at [time] [a.m.][p.m.], Eastern time, on August [●], 2020, as of the time of such confirmation no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

We have participated in conferences with officers and other representatives of the Company, representatives of the independent auditors of the Company and your representatives and counsel at which the contents of the Registration Statement, the General Disclosure Package and the Prospectus and related matters were discussed. Because the purpose of our professional engagement was not to establish or confirm factual matters and because we did not independently undertake to verify the accuracy, completeness or fairness of the statements set forth in the Registration Statement, the General Disclosure Package or the Prospectus, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus except insofar as such statements specifically relate to us or as specifically addressed in paragraphs 10 and 11 of our legal opinion addressed to you of even date herewith. Our identification of information as constituting the General Disclosure Package is for the limited purpose of making the statements set forth in this letter. We express no opinion or belief as to the conveyance of the General Disclosure Package or the Prospectus or the information contained therein to investors generally or to any particular investors at any particular time or in any particular manner.

On the basis of the foregoing, and except for (1) the financial statements and schedules and other information of an accounting or financial nature included or incorporated by reference therein, (2) the reserve and production information included or incorporated by reference therein, and (3) the Statements of Eligibility on Form T-1 of the Trustee, and any information derived therefrom, as to all of which we express no opinion or belief, no facts have come to our attention that led us to believe: (a) that the Registration Statement (and the documents incorporated by reference therein), at the time it became effective, or the Prospectus (and the documents incorporated by referenced therein), as of the date of the Final Prospectus Supplement, were not appropriately responsive in all material respects to the applicable requirements of the Securities Act, the Exchange Act and the Trust Indenture Act, and the applicable rules and regulations of the Commission thereunder; or (b)(i) that the Registration Statement, as of its most recent effective date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) that the General Disclosure Package, at the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) that the Prospectus, as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

▇-▇-▇

▇▇▇▇▇ ▇-▇

Form of Opinion of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇

(1) The Company and each of its subsidiaries have been duly organized and are validly existing and in good standing under the laws of their respective jurisdictions of organization and have all power and authority necessary to own or hold their respective properties and to conduct the businesses in which they are engaged, except where the failure to be in good standing or have such power or authority would not, individually or in the aggregate, have a Material Adverse Effect.

(2) The Company has an authorized equity capitalization as set forth in the Registration Statement, the Time of Sale Information and the Prospectus under the heading “Capitalization.”

(3) To the knowledge of such counsel, except as described in the Registration Statement, the Time of Sale Information and the Prospectus, there are no legal, governmental or regulatory investigations, actions, suits or proceedings pending to which the Company or any of its subsidiaries is or is reasonably expected to be a party or to which any property of the Company or any of its subsidiaries is or is reasonably expected to be the subject which, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect; and, to the knowledge of such counsel, no such investigations, actions, suits or proceedings are threatened by any governmental or regulatory authority or threatened by others.
