<p style="letter-spacing:-.1pt;margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">announced
the Trust income distribution for the month of May 2007. Unitholders of record
on May 31, 2007 will receive distributions amounting to $902,695 or
$0.484385214 per unit payable on July 31, 2007. </font><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Trust received $507,314 and $55,941 from the
New Mexico and Colorado portions of the San Juan Basin Properties,
respectively. Royalty income from the Hugoton Properties totaled $341,732.</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>
