Explanation of Responses:

( 1 )This amount includes 11,987 shares of common stock of QEP Resources, Inc. ("QEP") subject to restricted stock awards. ( 2 )On March 17, 2021, pursuant to the Agreement and Plan of Merger dated as of December 20, 2020 (the "Merger Agreement"), by and among Diamondback Energy, Inc. ("Diamondback"), Bohemia Merger Sub Inc., a wholly owned subsidiary of Diamondback ("Merger Sub"), and QEP, Merger Sub merged with and into QEP (the "Merger") with QEP surviving the Merger as a wholly-owned subsidiary of Diamondback. Pursuant to the Merger Agreement, each share of QEP common stock issued and outstanding immediately prior to the effective time of the Merger (the "Effective Time") (subject to certain exceptions) was converted into the right to receive 0.05 shares of Diamondback common stock (the "Exchange Ratio"). ( 3 )Pursuant to the Merger Agreement, at the Effective Time, any shares of QEP common stock subject to restricted stock awards were converted into a number of time-based restricted shares of Diamondback common stock (rounded to the nearest whole share) equal to the product of (i) the total number of shares of QEP common stock subject to such award immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio. ( 4 )Pursuant to the Merger Agreement, at the Effective Time, any compensation deferred by directors and deemed notionally invested in QEP common stock pursuant to any QEP deferred compensation plan became fully vested and converted into and deemed notionally invested in a number of shares of Diamondback common stock equal to the product of (A) the total number of shares of QEP common stock subject to such award immediately prior to the Effective Time multiplied by (B) the exchange ratio. Such deferred compensation will be paid in cash promptly following the effective date of the Merger (but not later than the time in which payment is required under the applicable QEP deferred compensation plan).
