                       Pioneer Receives Consents to Amend
              Evergreen's 5.875% Senior Subordinated Notes Due 2012

Dallas, Texas, November 1, 2004 -- Pioneer Natural Resources Company ("Pioneer")
(NYSE:PXD)  today  announced  that it has  received  consents  from holders of a
majority  of the  outstanding  5.875%  Senior  Subordinated  Notes due 2012 (the
"Notes"),  originally issued by Evergreen Resources, Inc. ("Evergreen") pursuant
to  the   previously   announced   solicitation   of  consents   (the   "Consent
Solicitation")  to amendments to the Indenture  dated March 10, 2004, as amended
and  supplemented,  by and  between  Pioneer (as  successor  to  Evergreen)  and
Wachovia Bank, National Association, as trustee, governing the Notes.

The amendments will be effective today and will:

         o        eliminate  the  subordination  of the right of  payment on the
                  Notes to the payment in full of all existing and future senior
                  indebtedness of Pioneer;

         o        amend  restrictive covenants  applicable to  the Notes so that
                  they are the  same as the  restrictive covenants  in Pioneer's
                  senior  notes that were originally issued as high-yield notes;
                  and

         o        amend the provisions of the Notes that suspend the restrictive
                  covenants when the Notes have certain investment grade ratings
                  so that  those provisions  are the same  as the suspension and
                  permanent-elimination  provisions in  Pioneer's  senior  notes
                  that were originally issued as high-yield notes.

Wachovia Bank,  National  Association  was the tabulation  agent for the Consent
Solicitation,  Credit Suisse First Boston LLC was the financial advisor and D.F.
King & Co., Inc. was the information agent.
