Ladies and Gentlemen:

Centennial Resource Production, LLC, a Delaware limited liability company (the “Company”) and subsidiary of Centennial Resource Development, Inc., a Delaware corporation (the “Parent”), 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”), $150,000,000 principal amount of its 3.25% Exchangeable Senior Notes due 2028 (the “Underwritten Securities”) and, at the option of the Underwriters, up to an additional $22,500,000 principal amount of its 3.25% Exchangeable Senior Notes due 2028 (the “Option Securities”) if and to the extent that the Underwriters shall have determined to exercise the option to purchase such 3.25% Exchangeable Senior Notes due 2028 granted to the Underwriters in Section 2 hereof. The Underwritten Securities and the Option Securities are herein referred to as the “Securities”. The Securities will be exchangeable into shares (the “Underlying Securities”) of Class A common stock of Parent, par value $0.0001 per share (the “Common Stock”), cash or a combination of shares of Common Stock and cash, at the Company’s option. The Securities will be issued pursuant to an Indenture to be dated as of March 19, 2021 (the “Indenture”), among the Company, the guarantors listed in Schedule 2 hereto (the “Guarantors”) and UMB Bank, N.A., as trustee (the “Trustee”), and will be guaranteed on a senior unsecured basis by each of the Guarantors (the “Guarantees”). As used herein, the term “Securities” shall include the Guarantees, unless the context otherwise requires.

In connection with the offering of the Underwritten Securities, the Company and the Parent are separately entering into capped call transactions with one or more counterparties, which may include the Underwriters or affiliates thereof (each, a “Capped Call Counterparty”), in each case pursuant to a capped call confirmation (each, a “Base Capped Call Confirmation”), each dated the date hereof, and in connection with the issuance of any Option Securities, the Company, the Parent and each Capped Call Counterparty may enter into additional capped call transactions, in each case pursuant to an additional capped call confirmation, each to be dated the date on which the option granted to the Underwriters to purchase such Option Securities pursuant to Section 2 hereof is exercised (each, an “Additional Capped Call Confirmation” and, together with the Base Capped Call Confirmations, the “Capped Call Confirmations”).

The Company and the Guarantors hereby confirm their agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company and the Guarantors have 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-3ASR (File No. 333-254300) including a base prospectus, relating to the Securities. Such registration statement, as amended at the time it became effective, including 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 each prospectus included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, 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 underwriting agreement (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 Exchange Act (as defined below) 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 of Sale (as defined below), the Company had prepared the following information (collectively, the “Time of Sale Information”): a Preliminary Prospectus dated March 15, 2021, and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

“Time of Sale” means 4:45 P.M., New York City time, on March 16, 2021.

2. Purchase of the Securities. (a) The Company agrees to issue and sell the Underwritten 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 Underwritten Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 97% of the principal amount thereof (the “Purchase Price”) plus accrued interest, if any, from March 19, 2021 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 public offering price of the Securities is not in excess of the price recommended by Jefferies LLC, acting as a “qualified independent underwriter” within the meaning of Rule 5121 of the Financial Industry Regulatory Authority, Inc. (“FINRA”).

In addition, the Company agrees to issue and sell the Option Securities to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option Securities at the Purchase Price plus accrued interest, if any, from March 19, 2021 to the date of payment and delivery.

If any Option Securities are to be purchased, the principal amount of Option Securities to be purchased by each Underwriter shall be the principal amount of Option Securities which bears the same ratio to the aggregate principal amount of Option Securities being purchased as the principal amount of Underwritten Securities set forth opposite the name of such Underwriter in Schedule 1 hereto (or such amount increased as set forth in Section 10 hereof) bears to the aggregate principal amount of Underwritten Securities being purchased from the Company by the several Underwriters, subject, however, to such adjustments to eliminate Securities in denominations other than $1,000 as the Representatives in their sole discretion shall make.

The Underwriters may exercise the option to purchase Option Securities at any time in whole, or from time to time in part, on or before the thirtieth day following the date of this Agreement, by written notice from the Representatives to the Company. Such notice shall set forth the aggregate principal amount of Option Securities plus accrued interest as to which the option is being exercised and the date and time when the Option Securities are to be delivered and paid for which may be the same date and time as the Closing Date but shall not be earlier than the Closing Date nor later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof). Any such notice shall be given at least one business day prior to the date and time of delivery specified therein.

(b) The Company and the Guarantors acknowledge and agree that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Securities on the terms set forth in the Time of Sale Information. The Company and the Guarantors acknowledge and agree that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

The time and date of such payment and delivery for the Underwritten Securities is referred to herein as the “Closing Date” and the time and date for such payment for the Option Securities, if other than the Closing Date, is herein referred to as the “Additional Closing Date”.

Payment for the Securities to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made by wire transfer in immediately available funds to the account(s) specified by the Company to the Representatives against delivery to the nominee of The Depository Trust Company (“DTC”), for the account of the Underwriters, of one or more global notes representing the Securities (collectively, the “Global Note”), with any transfer taxes payable in connection with the sale of the Securities duly paid by the Company. The Global Note will be made available for inspection by the Representatives not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date or the Additional Closing Date, as the case may be.

(d) The Company and the Guarantors acknowledge and agree that each Underwriter is 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, neither the Representatives nor 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) Blue Sky Compliance. The Company will qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will continue such qualifications in effect so long as required for distribution of the Securities; provided that neither the Company nor any of the Guarantors shall be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

During the period from the date hereof through and including the date that is 60 days after the date hereof, the Company and each of the Guarantors will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or publicly disclose the intention to undertake any of the foregoing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of Citigroup Global Markets Inc., other than (A) the Securities to be sold hereunder or any shares of

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, 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, (ii) or 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, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”) or any Time of Sale Information (including any Time of Sale Information that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the 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 paragraph (b) below.

The Company also agrees to indemnify and hold harmless, Jefferies LLC, its affiliates, directors and officers and each person, if any, who controls Jefferies LLC 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 incurred as a result of Jefferies LLC’s participation as a “qualified independent underwriter” within the meaning of FINRA Rule 5121 in connection with the offering of the Securities.

(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, officers and employees 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, any road show or any Time of Sale Information (including any Time of Sale Information that has subsequently been amended), it being understood and agreed that the only such information consists of the following information in the Prospectus furnished on behalf of each Underwriter: the third paragraph and eleventh paragraph, in each case under the caption “Underwriting (Conflicts of Interest).”

(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 and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of 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 paid or reimbursed as they are incurred; provided, however that if indemnity may be sought pursuant to the second paragraph of Section 7(a) above in respect of such proceeding, then in addition to such separate firm of the Underwriters, their affiliates and such control persons of the Underwriters the indemnifying party shall be liable for the fees and expenses of not more than one separate firm (in addition to any local counsel) for Jefferies LLC in its capacity as a “qualified independent underwriter”, its affiliates, directors, officers and all persons, if any, who control Jefferies LLC within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act. Any such separate firm for any Underwriter, its affiliates, directors, officers and employees 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, officers and employees who signed the Registration Statement and any control persons of the Company and the Guarantors 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. Notwithstanding

the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. 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) or (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 or Jefferies LLC in its capacity as a “qualified independent underwriter,” as the case may be, 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 or Jefferies LLC in its capacity as a “qualified independent underwriter,” as the case may be, 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 or Jefferies LLC in its capacity as a “qualified independent underwriter,” as the case may be, 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 or Jefferies LLC in its capacity as a “qualified independent underwriter,” as the case may be, 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 or Jefferies LLC in its capacity as a “qualified independent underwriter,” as the case may be, 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 paragraph (d) above 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 paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (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 paragraph (d) and this paragraph (e), 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 paragraph (d) and this paragraph (e) are several in proportion to their respective purchase obligations hereunder and not joint.

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

8. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

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 on or prior to the Closing Date or, in the case of the Option Securities, on or prior to the Additional Closing Date, (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; 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 Closing Date or the Additional Closing Date, as the case may be, 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 or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, 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 or the Additional Closing Date, as the case may be, 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, the Time of Sale Information 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, the Time of Sale Information 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 on the Closing Date or the Additional Closing Date, as the case may be does not exceed one-eleventh of the aggregate principal amount of all the Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Securities that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase on such date) 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 on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate principal amount of all the Securities to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Securities on the Additional Closing Date, as the case may be, 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 or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 11 hereof (except for any such expenses of a defaulting Underwriter) 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, the Guarantors or any non-defaulting Underwriter for damages caused by its default.

Cap Price

The cap price of the capped call transactions will initially be $8.4525 per share, which represents a premium of 75.0% above the Last Reported Sale Price per Share of Common Stock on Nasdaq on March 16, 2021, and is subject to certain adjustments under the terms of the capped call transactions.

FORM OF LOCK-UP AGREEMENT

Centennial Resource Development, Inc.

Lock-Up Agreement

March 16, 2021

Citigroup Global Markets Inc.

J.P. Morgan Securities LLC

Jefferies LLC

As Representatives of the several

Underwriters listed in Schedule 1 to the

Underwriting Agreement referred to below

c/o Citigroup Global Markets Inc.

388 Greenwich Street

New York, New York 10013

Re: Centennial Resource Development, Inc. – Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives, propose to enter into an underwriting agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named in Schedule 1 to the Underwriting Agreement (collectively, the “Underwriters”), with Centennial Resource Production, LLC, a Delaware limited liability company (the “Company”), and the guarantors listed in Schedule 2 to the Underwriting Agreement (the “Guarantors”), providing for a public offering of exchangeable senior notes of the Company (the “Securities”), exchangeable into shares of Class A Common Stock, par value $0.0001 per share (“Parent Common Stock”), of Centennial Resource Development, Inc., a Delaware corporation (the “Parent”), pursuant to the Registration Statement on Form S-3 (File No. 333-254300) filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Securities pursuant to the terms of the Underwriting Agreement, and of other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this agreement (this “Lock-Up Agreement”) and continuing to and including the date 60 days after the date set forth on the final prospectus used to sell the Securities (the “Stockholder Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, lend, grant any option to purchase, make any short sale or otherwise dispose of any shares of Parent Common Stock, or any options or warrants to purchase any shares of Parent Common Stock, or any securities convertible into, exchangeable for or that represent the right to receive shares of Parent Common Stock, whether now owned or hereafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively, the “Subject Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result

in a sale or disposition of the Subject Shares even if such shares of Parent Common Stock would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Subject Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such shares of Parent Common Stock.

Notwithstanding the foregoing, the undersigned may transfer the Subject Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, and (iii) with the prior written consent of Citigroup Global Markets Inc. on behalf of the Underwriters. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer shares of Parent Common Stock to any wholly-owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to any such transfer that the transferee execute an agreement stating that the transferee is receiving and holding such shares of Parent Common Stock subject to the provisions of this Lock-Up Agreement and there shall be no further transfer of such shares of Parent Common Stock except in accordance with this Lock-Up Agreement; and provided further that any such transfer shall not involve a disposition for value; and provided, further, that in the case of any transfer or distribution pursuant to clause (i) or (ii), no filing by any party under the Securities Exchange Act of 1934, as amended, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the Stockholder Lock-Up Period). The undersigned also agrees and consents to the entry of stop transfer instructions with the Parent’s transfer agent and registrar against the transfer of the Subject Shares except in compliance with the foregoing restrictions.

It is understood that if the Underwriting Agreement (other than the provisions thereof that survive the termination) shall terminate or be terminated prior to payment for and delivery of the Securities, the undersigned shall be automatically released from the obligations under this Lock-Up Agreement.

The undersigned understands that the Company, the Guarantors and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. Except as otherwise provided in this Lock-Up Agreement, the undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

Very truly yours,
