The plaintiffs in the lawsuit are royalty owners in oil and gas

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>
