<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">FOR IMMEDIATE RELEASE</font></p>

<p style="letter-spacing:-.1pt;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">AUSTIN,
TEXAS April 24, 2007 &#151; Mesa Royalty Trust (NYSE symbol-MTR) announced the Trust
income distribution for the month of April 2007. Unitholders of record on April
30, 2007 will receive distributions amounting to $809,607 or $0.434434339 per
unit payable on July 31, 2007. </font><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
Trust received $391,631 and $53,187 from the New Mexico and Colorado portions
of the San Juan Basin Properties, respectively. Royalty income from the Hugoton
Properties totaled $369,561.</font></p>

<p style="letter-spacing:-.1pt;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">As previously announced, </font><font size="2" face="Times New Roman" style="font-size:10.0pt;">Pioneer Natural Resources USA, Inc. </font><font size="2" face="Times New Roman" style="font-size:10.0pt;">(&#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>

in which the Trust has an interest will continue to be dependent on normal
factors associated with oil and gas operations such as oil and gas production
levels, 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>
