      The undersigned hereby grants to each attorney-in-fact full power
and authority to do and perform all and every act and thing whatsoever
requisite, necessary or proper to be done in the exercise of any of the
rights and powers herein granted, as fully to all intents and purposes

      The undersigned agrees that each such attorney-in-fact may rely

to the undersigneds holdings of and transactions in securities issued by
Concho Resources Inc., unless earlier revoked by the undersigned in a
signed writing delivered to the foregoing attorneys-in-fact. This Power
of Attorney revokes all other powers of attorney that the undersigned
