                          Independent Auditors' Report

To the Participants and Administrator of
   the Pioneer Natural Resources Company
   Deferred Compensation Retirement Plan:

We have audited the accompanying  statement of net assets available for benefits
of Pioneer Natural Resources Company Deferred Compensation  Retirement Plan (the
"Plan") as of December  31,  1997,  and the related  statement of changes in net
assets  available  for  benefits  for the  period  from  August 8, 1997 (date of
inception)  through  December  31,  1997.  These  financial  statements  are the
responsibility  of the Plan's  management.  Our  responsibility is to express an
opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the net assets available for benefits of the Plan as of
December 31, 1997, and the changes in net assets  available for benefits for the
period  from August 8, 1997 (date of  inception)  through  December  31, 1997 in
conformity with generally accepted accounting principles.

Our audit was  performed  for the  purpose  of  forming  an opinion on the basic
financial  statements taken as a whole. The Fund Information in the statement of
changes in net assets  available  for  benefits  is  presented  for  purposes of
additional  analysis rather than to present the changes in net assets  available
for plan benefits of each fund. The Fund  Information  has been subjected to the
auditing procedures applied in the audit of the basic financial  statements and,
in our opinion,  are fairly  stated in all material  respects in relation to the
basic financial statements taken as a whole.

                                December 31, 1997


Note 1.     Description of Plan

       The following brief  description of the provisions of the Pioneer Natural
Resources Company Deferred Compensation Retirement Plan ("the Plan") is provided
for general  information  purposes only.  Eligible employees should refer to the
Plan  document  for more  complete  information.  The Plan is not subject to the
provisions of the Employee Retirement Income Security Act of 1974 ("ERISA") (See
Note 6).

       General

       The Plan is a defined  contribution plan available to eligible  employees
of Pioneer Natural Resources  Company ("the Employer").  An eligible employee is
any  individual  who is employed by the Employer and (i) is an officer or (ii) a
member of a select group of management or highly  compensated  employees who are
designated by the  Compensation  Committee of the Board of Directors  (the "Plan
Administrator")  from time to time as being eligible to participate in the Plan.
Certain  administrative  functions such as  maintenance of account  balances and
allocation of earnings are performed by the Vanguard Group.

       Contributions

       Participants  may elect to contribute up to a maximum  amount of 25% from
their pay and/or bonus. The Employer  contributes to the Plan an amount equal to
100% of a  participant's  contribution  not to exceed 8% of salary  for a select
group of management or 10% of salary for officers.  The Employer's  contribution
amounted  to $268,758  for the period  from  August 8, 1997 (date of  inception)
through December 31, 1997.

       Participant Accounts

       Each   participant's   account  is   credited   with  the   participant's
contributions,  the Employer's matching  contributions and an allocation of Plan
earnings.  The net return on  investments  is  allocated  to each  participant's
account in proportion to the account value of the participant's account relative
to the entire equity investment portfolio.

       Investment Options

       Participants may invest their account balance in any of, or a combination
of, 19  investment  funds.  Employer  contributions  are allocated on a pro rata
basis to the participant's selected fund(s).

        long-term  growth of capital and income from dividends by holding all of
        the 500  stocks  that  make  up the  unmanaged  Standard  &  Poor's  500
        Composite Stock Price Index, a widely recognized benchmark of U.S. stock
        market performance.

        to  provide  long-term  growth of  capital  by  attempting  to match the

        long-term growth of capital, without undue risk to capital, by investing
        about 65% of its assets in stocks and the remaining 35% in bonds.

   o    Vanguard/Windsor II (32 participants): Seeks to provide long-term growth
        of capital and income from dividends by investing in a diversified group
        of out-of-favor  stocks of  large-capitalization  companies.  The stocks
        generally sell at prices below the overall  market  average  compared to
        their dividend income and future return potential.

   Vesting

       A member  shall have a 100% vested  interest  in his general  account and
matching contribution account at all times.

Note 2.     Summary of Significant Accounting Policies

       Basis of Presentation

       The accompanying  financial  statements have been prepared on the accrual
basis of accounting.

       Trust Accounting

       The Plan's  assets are held with  Vanguard  Fiduciary  Trust Company (the
"Trustee").

       Investment Valuation

       Investments  are valued at fair value as determined by the Trustee.  Fair
value is determined as follows:

    1)     Investments in securities traded on national securities exchanges are
           valued at  the last  reported sales price on the last business day of
           the year;

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997


Note 2.     Summary of Significant Accounting Policies (continued)

    2)    Securities  traded on  over-the-counter  markets and listed securities
          for which no sales were  reported on that date,  if any, are valued at
          the mean between the last reported bid and asked prices; and

    3)    Investments in restricted  securities and other security  investments,
          if any, not having an  established  market are valued at fair value as
          determined by the investment manager of the trust.

       Payments of Benefits

       The total value of the vested portion of the  participant's  account will
be paid in one  lump  sum as soon as  administratively  possible,  or in  annual
installment payments for a term of either five or ten years.

       Withdrawal of Benefits

       Employees  may withdraw  their vested  interest in the Plan under certain
hardship  conditions as defined in the Plan.  Terminated  participants  may also
withdraw their vested interest in the Plan.

       Security Transactions and Investment Income

       Security  transactions are accounted for on a trade-date basis.  Expenses
incurred with transactions,  if any, are added to the purchase price or deducted
from the  selling  price at the time of the  transactions.  Dividend  income  is
recorded on the ex-dividend  date.  Income from other investments is recorded as
earned on an accrual basis.

       Use of Estimates

       The  preparation  of financial  statements in conformity  with  generally
accepted accounting principles requires the Plan Administrator to make estimates
and  assumptions  that affect the reported  amounts of net assets  available for
benefits at the date of the financial statements and the reported changes in net
assets available for benefits during the reporting periods. Actual results could
differ from those estimates.

Note 4.     Plan Termination

       Although it has not  expressed  any intent to do so, the Employer has the
right  under  the  Plan to  discontinue  its  contributions  at any  time and to
terminate the Plan in the manner specified by the Plan Administrator,  which may
include the payment of a single lump sum or cash payment in full satisfaction of
a participant's benefits.

Note 5.     Administrative Expenses

       The  Employer  may pay all  expenses  incurred in the  establishment  and
administration of the Plan,  including expenses and fees of the Trustee,  but it
shall  not be  obligated  to do so,  and any  such  expenses  not so paid by the
Employer  shall be paid from Plan  earnings.  The  Employer  paid  approximately
$4,000 in administrative expenses relating to 1997.

Note 6.     Tax Status of the Plan

       On October 31, 1997,  Pioneer Natural Resources Company filed notice with
the Pension and Welfare Benefits Administration, U.S. Department of Labor, for a
Top Hat Plan exemption from the ERISA reporting requirements.  Pioneer maintains
this  non-qualified  retirement  plan  primarily  for the  purpose of  providing
deferred  compensation  to a  select  group  of  highly  compensated  management
employees.

       Certain Plan  investments  are shares of mutual funds managed by Vanguard
Fiduciary  Trust  Company.  Vanguard  Fiduciary  Trust Company is the Trustee as
defined   by  the  Plan  and,   therefore,   these   transactions   qualify   as
party-in-interest.
