<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">AUSTIN,
TEXAS October 23, 2006 &#151; Mesa Royalty Trust (NYSE symbol-MTR) announced the
Trust income distribution for the month of October 2006. Unitholders of record
on October 31, 2006 will receive distributions amounting to $313,899 or $0.168437900
per unit payable on January 31, 2007. Royalty income from the San Juan Basin
Properties totaled $316,995. There was no royalty income from the Hugoton
Properties.</font></p>

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

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Under the
terms of the agreement, Pioneer USA 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>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Pioneer&#146;s
portion of the cash payment is expected to be approximately $32 million. The
cash portion will be paid in two installments.&#160;
Pioneer has advised the Trustee that the portion of the cash payments
net to the Trust&#146;s interest will be approximately </font>$1.1 million payable on September 30, 2006
and $1.0 million payable on September 30, 2007.&#160; Pioneer
USA will initially pay the costs attributable to the Trust&#146;s interest but will
recover these costs through payments</p>

be reduced until all of these payments, together with any applicable interest
as provided under the overriding royalty conveyance of the Trust&#146;s properties,
are recouped by Pioneer USA.&#160; In
connection with this settlement arrangement, royalty income to the Trust was
reduced by approximately $397,000 for the month of October 2006.</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;">The extent of future distributions from the properties 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.</font></p>
