<p style="letter-spacing:-.1pt;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;letter-spacing:0pt;">AUSTIN, TEXAS July 24, 2007 &#151; Mesa Royalty Trust (NYSE
symbol-MTR) announced the Trust income distribution for the month of July 2007.
Unitholders of record on July 31, 2007 will receive distributions amounting to
$1,150,548 or $0.617382790 per unit payable on October 31, 2007. </font><font size="2" face="Times New Roman" style="font-size:10.0pt;letter-spacing:0pt;">The Trust received $522,849
and $268,344 from the New Mexico and Colorado portions of the San Juan Basin
Properties, respectively. Royalty income from the Hugoton Properties totaled $353,248.</font></p>

<p style="letter-spacing:-.1pt;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;letter-spacing:0pt;">As previously announced, </font><font size="2" face="Times New Roman" style="font-size:10.0pt;letter-spacing:0pt;">Pioneer Natural Resources USA, Inc. </font><font size="2" face="Times New Roman" style="font-size:10.0pt;letter-spacing:0pt;">(&#147;Pioneer USA&#148;) reached
an agreement to settle claims made in the lawsuit <i>John Steven Alford and Robert Larrabee, individually
and on behalf of a Plaintiff Class v. Pioneer Natural Resources USA, Inc</i>.&#160; The plaintiffs in the lawsuit are royalty
owners in oil and gas properties located in the Hugoton field, which are owned
by Pioneer USA, a subsidiary of Pioneer Natural Resources Company (&#147;Pioneer&#148;).&#160; The plaintiffs sued a predecessor company to
Pioneer USA asserting various claims relating to alleged improper deductions in
the calculation of royalties. Under the
terms of the agreement, Pioneer USA has made and will make cash payments to
settle the plaintiffs&#146; claims with respect to production occurring on and
before December 31, 2005.&#160; Pioneer USA
also agreed to adjust the manner in which royalty payments to the class members
will be calculated for production occurring on and after January 1, 2006.</font></p>

prices and associated cost, accruals for future abandonment costs, timing and
extent of capital expenditures, as well as a recoupment, by Pioneer USA, of
approximately $0.9 million payable on September 30, 2007 in connection with
certain litigation.</font></p>
