Item 5.02.  Departure of Directors or Principal  Officers;  Election of
Directors;  Appointment  of Principal  Officers;  Compensatory Arrangements of
Certain Officers.


        1. On February 26, 2007, the Compensation and Management Development
Committee (the "Committee") of the Board of Directors of Pioneer Natural
Resources Company (the "Company") established targets for the Company's named
executive officers for 2007 bonuses payable in 2008 under the Company's Annual
Incentive Bonus Plan (the "Plan"), as described below. The "named executive
officers" are the executive officers of the Company for whom disclosure was
required in the Company's proxy statement for its 2006 Annual Meeting of
Stockholders. The 2007 bonus target is shown as a percentage of 2007 base
salary, and the actual amount paid may be at, above or below the target level:

        Named Executive Officer   2007 Bonus Target
        -----------------------   -----------------
        Scott D. Sheffield        100%
        Timothy L. Dove            85
        A.R. Alameddine            65
        Chris J. Cheatwood         65
        Danny L. Kellum            65

Base salaries for the named executive officers payable during 2007 are unchanged
from 2006 levels.

        The award of 2007 bonuses under the Plan will be based on the
Committee's judgment regarding the Company's and the executive officer's
performance in 2007, considering, among other things, the objectives established
by the Committee. The corporate objectives include both financial and
non-financial objectives. Financial objectives for 2007 include oil and gas
production, operating expense levels, general and administrative expense levels,
year-end indebtedness, finding costs, reserve replacement, return on equity and
net asset value per share. Another corporate objective is based on the Company's
performance in the areas of safety and environmental. Certain non-financial
objectives vary by executive officer depending on his area of responsibility.

        2. On February 26, 2007, the Committee also made awards of
restricted stock and performance units to the named executive officers, as
follows.




                                  Number of Restricted    Number of Performance
        Named Executive Officer      Shares Awarded           Units Awarded
        -----------------------   --------------------    ---------------------
                                                           
        Scott D. Sheffield              34,997                   34,998
        Timothy L. Dove                 15,165                   15,166
        A.R. Alameddine                  5,833                    5,833
        Chris J. Cheatwood               8,166                    8,166
        Danny L. Kellum                  8,166                    8,166



The equity awards were made under the Company's 2006 Long-Term Incentive Plan
pursuant to the forms of Restricted Stock Award Agreement and Performance Unit
Award Agreement filed as exhibits to this report and incorporated herein by
reference.

        3. On February 26, 2007, the Committee also amended the agreements
pursuant to which restricted stock was granted to the named executive officers
of the Company on February 14, 2006. As a result of the amendment, the terms
governing the effect of various termination events on the vesting of
                                       3


such restricted stock will be identical to the terms governing the effect of
such events that are set forth in the Restricted Stock Award Agreement filed as
an exhibit to this report.

        4. On February 26, 2007, the Committee also determined the amount of
cash bonuses payable to the named executive officers, based on the Committee's
assessment of 2006 performance. The bonuses were paid on March 2, 2007, as
follows:

        Named Executive Officer   Amount of 2006 Cash Bonus
        -----------------------   -------------------------
        Scott D. Sheffield        $ 850,000
        Timothy L. Dove             446,250
        A.R. Alameddine             243,100
        Chris J. Cheatwood          243,100
        Danny L. Kellum             276,250


Item 5.05. Amendments to the Registrant's Code of Ethics, or Waiver of a
Provision of the Code of Ethics.

        On February 27, 2006, the Board of Directors of the Company adopted a
new Code of Business Conduct and Ethics (the "Code"), which applies to the
Company's directors, employees and officers, including its principal executive
officer, principal financial officer and principal accounting officer. In order
to permit the Company to develop training and communications materials and
otherwise prepare for the introduction of the Code to the Company's employees,
the adoption of the Code will be effective June 1, 2007.

        The Code is filed as an exhibit to this report and incorporated herein
by reference.
