 with Section 16 of the Securities Exchange Act of 1934 and the rules and interpretations
 promulgated thereunder, and Forms 144 pursuant to Rule 144 of the General Regulations under
 the Securities Act of 1933 and the rules and interpretations promulgated thereunder, with respect
 to the ownership by or attributable to the undersigned, directly or indirectly, of equity securities
 of the Company or derivative securities relating thereto, and units of beneficial interest in the
 Cross Timbers Royalty Trust and Hugoton Royalty Trust;

	(2)	do and perform any and all acts for and on behalf of the undersigned which may
 be necessary or desirable to complete and execute any such Form 3, 4, 5, or 144, complete and
 execute any amendment(s) thereto, and timely file such form with the United States Securities
 and Exchange Commission and any stock exchange or similar authority; and

	(3)	take any other action of any type whatsoever in connection with the foregoing
 which, in the opinion of such attorney-in-fact, may be of benefit to, in the best interest of,

	The undersigned hereby grants to each such attorney-in-fact full power and authority to
 do and perform any and every act and thing whatsoever requisite, necessary, or proper to be done
