Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On July 19, 2018, pursuant to the Agreement and Plan of Merger dated as of March 27, 2018 (the "Merger Agreement"), by and among Concho Resources Inc. ("Concho"), Green Merger Sub Inc. ("Merger Sub") and RSP Permian, Inc. ("RSP"), Merger Sub merged with and into RSP (the "Merger"), with RSP surviving the Merger as a wholly owned subsidiary of Concho.
(2) Pursuant to the Merger Agreement, each share of RSP common stock issued and outstanding immediately prior to the effective time of the Merger (including each outstanding share of time-based restricted stock of RSP that vested in full and was treated as a share of RSP common stock for purposes of the Merger Agreement) was converted into the right to receive 0.320 of a share of Concho common stock. On July 18, 2018 (the day prior to the Merger), the closing price of one share of Concho common stock was $149.66. Withholding for the payment of tax liabilities in connection with the vesting of restricted stock awards was effectuated following conversion into shares of Concho common stock.
(3) Mr. Grimm is a manager of the general partner of Grimm Family Limited Partnership and therefore may be deemed to indirectly beneficially own these securities. Mr. Grimm disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein.
