     This Amendment No. 1 to Schedule 13D is filed by Pioneer Natural Resources
USA, Inc., a Delaware corporation ("Pioneer USA"), and Pioneer Natural Resources
Company, a Delaware corporation ("Pioneer"). Pioneer USA and Pioneer are
collectively referred to herein as "Reporting Persons."
     This Amendment No. 1 amends and restates Items 4, 5, 6, and 7 contained in
the Schedule 13D dated February 8, 2000, and filed by each of the Reporting
Persons (the "Prior Filing"). Items 1, 2 and 3 of the Prior Filing remain
unchanged.
ITEM 4. PURPOSE OF THE TRANSACTION.
     On March 28, 2000, Pioneer USA entered into a Stock Purchase Agreement (the
"Purchase Agreement") with Prize Energy Corp. ("Issuer") whereby effective as of
MARCH 31, 2022 (the "Effective Date") the following occurred: (i) Pioneer USA
converted 3,984,197 shares of Series A 6% Convertible Preferred Stock of Issuer
into 3,984,197 shares of common stock of Issuer, par value $0.01 per share
("Common Stock"); (ii) Issuer purchased 1,346,482 shares of Common Stock from
Pioneer USA immediately upon such conversion; (iii) Issuer paid Pioneer USA a
cash dividend of $458,514 in lieu of the payment-in-kind dividend that otherwise
would have been due; (iv) Pioneer USA relinquished all of its rights under that
certain Voting and Shareholders Agreement, dated as of February 8, 2000, by and
among Pioneer USA, Issuer, and certain other Stockholders of Issuer (the "Voting
and Shareholders Agreement"), including Pioneer USA's right to designate two
directors of Issuer; and (v) Pioneer USA and Issuer agreed to terminate that
certain Joint Participation Agreement, dated as of June 29, 1999, by and between
Pioneer USA and Issuer, as assignee of such agreement (the "Joint Participation
Agreement"), which provided in part for Pioneer USA's right to participate in
certain future prospects of Issuer. In addition, effective as of the Effective
Date, Pioneer USA's two representatives on Issuer's board of directors resigned
as directors of the Issuer.
     The foregoing summary of the terms of the Purchase Agreement is qualified
in its entirety by reference to the Purchase Agreement, which is incorporated
herein by reference.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.
     (a) and (b). Each Reporting Person is the beneficial owner of 2,637,715
shares of Common Stock, or 19.9% of the outstanding shares of Common Stock. Each
Reporting Person has the sole power to vote and dispose of the shares.
     (c) and (d). On March 28, 2000, Pioneer USA agreed to sell 1,346,482 shares
of Common Stock to the Issuer for an amount equal to $13.50 per share, for a
total purchase price of $18,177,507. Such sale became effective as of the
Effective Date. On the Effective Date, Issuer paid Pioneer USA a cash dividend
of $458,514 in lieu of the payment-in-kind dividend that otherwise would have
been due. None of the executive officers or directors of either of the Reporting
Persons effected any transactions in Common Stock during the past 60 days, and
no person is known to have the right to receive or the power to direct the
receipt of dividends from, or the proceeds from the sales of, the Common Stock
owned by the Reporting Persons.
     (e) Not applicable.
ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
THE SECURITIES OF THE ISSUER.
     All of the rights and obligations of the Reporting Persons under the Voting
and Shareholders Agreement were terminated as of the Effective Date.
     The Reporting Persons are not party to any other contracts, arrangements,
understandings or relationships (legal or otherwise) with respect to any
securities of the Issuer.

Participation Agreement, providing, among other things, for Pioneer's right to
participate in certain future projects of Prize (the "Joint Participation
