                        PIONEER NATURAL RESOURCES COMPANY

Item 1.01.   Entry into a Material Definitive Agreement

     On January 27, 2005,  Pioneer  Natural  Resources  Company (the  "Company")
issued a news  release  that is  attached  hereto as exhibit  99.1.  In the news
release,  the Company announced that it has sold to Royalty Acquisition Company,
LLC (the "Purchaser") approximately two percent of its total proved reserves, or
20.5  million  barrels  of oil  equivalent  proved  reserves,  by  means  of two
volumetric  production  payments ("VPPs") for total proceeds of $593 million and
the assumption of the Company's obligations under certain derivative agreements,
referred to below. The production payment purchase and sale agreements governing
the VPP transactions are attached hereto as exhibits 99.2 and 99.3.

     The Purchaser and Wachovia Bank, N.A.  ("Wachovia  Bank") are  subsidiaries
and/or affiliates of Wachovia Corporation.  The Company periodically enters into
derivative  agreements  with  Wachovia  Bank to hedge  commodity  price risk and
interest  rate risk.  In  accordance  with the terms of the VPPs,  the Purchaser
assumed  the  Company's   rights  and  obligations   under  certain   derivative
agreements.  The  counterparty  to the  derivative  obligations  assumed  by the
Purchaser is Wachovia Bank.  Wachovia Bank is also a party to the Company's $700
million  5-Year  Revolving  Credit  Agreement  dated as of December 16, 2003, as
amended,  and to the Company's $900 million 364-Day Credit Agreement dated as of
September 28, 2004, as amended.

     The VPPs represent is a limited term  overriding  royalty  interests in oil
and  gas  reserves  which:  (i)  entitle  the  Purchaser  to  receive  scheduled
production volumes over a period of time from specific lease interests; (ii) are
free and clear of all associated  future operating costs,  capital  expenditures
and production and ad valorem taxes;  (iii) are nonrecourse to the seller (i.e.,
the Purchaser's only recourse is to the assets acquired); (iv) transfer title to
the proved reserves to the buyer and (v) allow for retention by the Company of a
residual interest in the assets after the VPPs volumetric  obligations have been
satisfied.

     The first VPP on  approximately  58  billion  cubic feet  primarily  of the
Company's Hugoton field gas volumes has an approximate  five-year term beginning
February 1, 2005 and ending  December 31, 2009. The second VPP on  approximately
10.8  million  barrels of  Spraberry  field oil  volumes has a  seven-year  term
beginning January 1, 2006 and ending December 31, 2012.
