THIS FIRST AMENDMENT TO EMPLOYMENT AGREEMENT (this “Amendment”) is entered into by and between Matthew R. Owens
(“Executive”), Extraction Oil & Gas, Inc. (“Extraction”), and Civitas Resources, Inc. (each of which are referred to individually as a “Party” and together as the
“Parties”). 
 WHEREAS, Executive and Extraction entered into that certain Employment Agreement effective as of the
effective date of Extraction’s chapter 11 plan of reorganization (the “Agreement”) and the Parties desire to amend the Agreement to modify certain terms of the original Agreement; and 

WHEREAS, Extraction, Raptor Eagle Merger Sub, Inc., and Bonanza Creek Energy, Inc. have entered into that certain Agreement and Plan of Merger
dated as of May 9, 2021, which is expected to close (the “Closing”) on November 1, 2021, in conjunction with which Bonanza Creek Energy, Inc. will change its name to Civitas Resources, Inc.
(“Civitas”). 
 NOW THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, each Party agrees as follows: 
 1.
    Capitalized Terms. Capitalized terms used but not otherwise defined herein shall have the meaning assigned to them in the Agreement. 

2.     Amendment Effective Date. The Amendment shall be effective upon the Closing (the “Amendment
Effective Date”). 
 3.     Substitution of Company and Novation. The Agreement shall be amended so
that all references in the Agreement to Extraction or the Company shall instead be to Civitas. The Parties hereby agree that Civitas shall assume and be solely responsible for all rights and obligations of the Company under the Agreement, whether
arising before or after the Amendment Effective Date, and that Extraction shall be fully novated and released from all further obligations under the Agreement. Executive hereby stipulates and agrees that, so long as the Civitas board of directors
elects him to the office of Chief Operating Officer of Civitas in conjunction with the Closing, he shall not have experienced a termination of his employment with the Company as a result of the transfer of his employment from Extraction to Civitas.

 4.    Miscellaneous. 

(a)    Continuation of Agreement. From and after the date of this Amendment, all references to the Agreement set
forth therein or in any other agreement shall, unless otherwise specifically provided, be references to the Agreement as amended by this Amendment and as may be further amended, modified, restated or supplemented from time to time by the Parties.
This Amendment is limited as specified and shall not constitute or be deemed to constitute an amendment, modification or waiver of any provision of the Agreement except as expressly set forth herein. As amended hereby, the Agreement shall continue
in full force and effect according to its terms. 
 (b)    Counterparts. This Amendment may be executed by in any
number of counterparts, each which shall be deemed an original instrument, but all of which together shall constitute but one and the same instrument.
