                       2000 ANNUAL MEETING OF STOCKHOLDERS

         The board of directors of Pioneer Natural Resources Company (the "Board
of Directors")  requests your Proxy for the Annual Meeting of Stockholders  that
will be held at 9:00 a.m.,  on Thursday,  May 18, 2000,  in the Miro Room at the
Wyndham Anatole Hotel, Dallas,  Texas 75207 (the "Annual Meeting").  By granting

shares at any adjournments or postponements of the meeting.

         You may grant your Proxy by signing,  dating and returning the enclosed
paper proxy card.  Instead of returning the paper proxy card, you may complete a
proxy card  electronically  through the Internet by accessing the website of the
Company's transfer agent at www.continentalstock.com.  You will need the control

         If you attend the Annual  Meeting,  you may vote in person.  If you are
not present at the Annual Meeting,  your shares may be voted only by a person to
whom  you have  given a  proper  proxy,  such as the  accompanying  Proxy or the
Internet  Proxy.  You may revoke  the Proxy in writing at any time  before it is
exercised at the Annual  Meeting by delivering to the Secretary of the Company a
written notice of the revocation,  or by signing and delivering to the Secretary
of  the  Company  a  proxy  with  a  later  date  or  by  submitting  your  vote
electronically  through the Internet with a later date.  Your  attendance at the
Annual  Meeting  will not revoke the Proxy  unless  you give  written  notice of
revocation  to the  Secretary  of the Company  before the Proxy is  exercised or
unless you vote your shares in person at the Annual Meeting.

         This Proxy Statement and the accompanying  Notice of Annual Meeting and
Proxy are first being sent or given to  stockholders  of the Company on or about
April 10, 2000.

                                QUORUM AND VOTING

             Voting Stock. The Company has two outstanding classes of securities
that  entitle   holders  to  vote   generally  at  meetings  of  the   Company's
stockholders:  common  stock,  par value $.01 per share;  and Special  Preferred
Voting Stock,  par value $.01 per share. A single share (the "Voting  Share") of
Special  Preferred  Voting Stock was issued to Montreal  Trust Company of Canada
(the  "Trustee") as trustee under a Voting and Exchange Trust  Agreement for the
benefit of holders of exchangeable  shares issued by the Company's wholly- owned
subsidiary,  Pioneer  Natural  Resources  Canada Inc.,  in  connection  with the
Company's  December 1997 acquisition of Chauvco  Resources Ltd. The common stock
and the Voting Share vote together as a single class on all matters  except when
Delaware law requires  otherwise.  Each share of common stock outstanding on the
record date is entitled  to one vote.  The Voting  Share is entitled to one vote
for each  exchangeable  share  outstanding  on the record  date.  The Trustee is
required  to vote the Voting  Share in the manner that  holders of  exchangeable
shares  instruct,  and to abstain from voting in proportion to the  exchangeable
shares  for  which  the  Trustee  does not  receive  instructions.  Accordingly,
references to  "stockholders"  in this Proxy Statement include holders of common
stock,  the Trustee,  and holders of  exchangeable  shares.  The  procedures for
holders of  exchangeable  shares to  instruct  the Trustee  about  voting at the
Annual  Meeting  are  explained  in the  "Information  Statement  for Holders of
Exchangeable  Shares of Pioneer Natural  Resources Canada Inc." that is enclosed
with this Proxy Statement only for holders of exchangeable shares.

         Record Date. The record date for stockholders entitled to notice of and
to vote at the Annual  Meeting is the close of business on April 3, 2000. At the
record  date,  96,269,736  shares of  common  stock and one  Voting  Share  were
outstanding and entitled to be voted at the Annual Meeting.  At the record date,
3,568,562  exchangeable  shares  were  outstanding  and  entitled to give voting
instructions to the Trustee.  Accordingly,  99,838,298  votes are eligible to be
cast at the Annual Meeting.


<PAGE>



         Quorum and  Adjournments.  The presence,  in person or by proxy, of the
holders of a majority of the votes  eligible to be cast at the Annual Meeting is
necessary to constitute a quorum at the Annual Meeting.

         If a quorum is not present,  the stockholders  entitled to vote who are
present  in person or by proxy at the Annual  Meeting  have the power to adjourn
the Annual Meeting from time to time,  without notice other than an announcement
at the  Annual  Meeting,  until a quorum is  present.  At any  adjourned  Annual
Meeting at which a quorum is present,  any business may be transacted that might
have been transacted at the Annual Meeting as originally notified.

         Vote  Required.  Directors  will be elected by a plurality of the votes
present and  entitled  to be voted at the Annual  Meeting.  Ratification  of the
selection of the  Company's  auditors will require the  affirmative  vote of the
holders of a majority  of the shares  present  and  entitled  to be voted at the
Annual  Meeting.   An  automated  system  that  the  Company's   transfer  agent
administers will tabulate the votes.  Brokers who hold shares in street name for
customers are required to vote shares in accordance with  instructions  received
from the beneficial owners. Brokers are permitted to vote on discretionary items
if they have not received  instructions from the beneficial owners, but they are
not permitted to vote (a "broker  non-vote") on  non-discretionary  items absent
instructions  from the beneficial  owner.  Abstentions and broker non-votes will
count in  determining  whether a quorum is present at the Annual  Meeting.  Both
abstentions  and broker  non-votes  will not have any  effect on the  outcome of
voting on director elections.  For purposes of voting on the ratification of the
selection  of  auditors,  abstentions  will be  included in the number of shares
voting  and will have the  effect of a vote  against  the  proposal,  and broker
non-votes will not be included in the number of shares voting and therefore will
have no effect on the outcome of the voting.

         Default Voting. A Proxy that is properly completed and returned will be
voted at the Annual Meeting in accordance with the instructions on the Proxy. If
you  properly  complete  and return a Proxy,  but do not  indicate  any contrary
voting instructions, your shares will be voted as follows:

         o    FOR the election of the two persons named in this Proxy  Statement
              as the Board of  Directors'  nominees for election to the Board of
              Directors.

         o    FOR the  ratification of the selection of Ernst & Young LLP as the
              Company's auditors.

If any other business  properly comes before the  stockholders for a vote at the
meeting,  your shares will be voted in  accordance  with the  discretion  of the
holders of the Proxy.  The Board of  Directors  knows of no matters,  other than
those  previously  stated,  to be  presented  for  consideration  at the  Annual
Meeting.

                                    ITEM ONE

                              ELECTION OF DIRECTORS

         The Board of Directors has nominated the following persons for election
as Class III  directors  of the Company with their terms to expire at the annual
meeting of stockholders in 2003 when their successors are elected and qualified:

                                 Jerry P. Jones
                             Charles E. Ramsey, Jr.

         Both of these  nominees  are  currently  serving  as  directors  of the
Company. Their biographical information is contained in "Directors and Executive
Officers."

         The Board of  Directors  has no reason to  believe  that  either of its
nominees will be unable or unwilling to serve if elected.  If a nominee  becomes
unable or unwilling to accept  nomination or election,  either the number of the
Company's  directors  will be reduced or the persons acting under the Proxy will
vote for the  election  of a  substitute  nominee  that the  Board of  Directors
recommends.

         The  Board  of  Directors  recommends  that  stockholders  vote FOR the
election of each of the nominees.

                                    ITEM TWO

                              SELECTION OF AUDITORS

         The Board of Directors  has selected  Ernst & Young LLP as the auditors
of the Company  for 2000.  Ernst & Young LLP  audited  the  Company's  financial
statements  for 1999 and 1998. The 1999 audit was completed on January 24, 2000.
The Company expects that representatives of Ernst & Young LLP will be present at
the Annual Meeting to respond to  appropriate  questions and to make a statement
if they desire to do so.

         The report of Ernst & Young LLP on the Company's  financial  statements
for 1999 and 1998 did not contain an adverse  opinion or a disclaimer of opinion
and was not qualified or modified as to uncertainty,  audit scope, or accounting
principles.

         In connection with the audits of the Company's financial statements for
1999 and 1998, there were no disagreements with Ernst & Young LLP on any matters
of accounting  principles  or  practices,  financial  statement  disclosure,  or
auditing scope or procedures  which, if not resolved to the satisfaction of such
independent accountants,  would have caused such independent accountants to make
reference to the matter in their report.

         The  Board  of  Directors   recommends  that   stockholders   vote  FOR
ratification of the selection of Ernst & Young LLP.

                        DIRECTORS AND EXECUTIVE OFFICERS

         After the Annual Meeting,  assuming the stockholders elect the nominees
of the Board of Directors as set forth in "Item  One-Election of Directors," the
Board of Directors and executive officers of the Company will be:

         Name                Age                     Position

Scott D. Sheffield.......    47    Chairman of the Board, President and Chief
                                   Executive Officer
Timothy L. Dove..........    43    Executive Vice President and Chief Financial
                                   Officer
Dennis E. Fagerstone.....    51    Executive Vice President
Mark L. Withrow..........    52    Executive Vice President, General Counsel and
                                   Secretary
Danny L. Kellum..........    45    Vice President - Domestic Operations
James R. Baroffio........    68    Director
R. Hartwell Gardner......    65    Director

Jerry P. Jones...........    68    Director
Charles E. Ramsey, Jr....    63    Director
Robert L. Stillwell......    63    Director

         The Company has  classified its  Board of Directors into three classes.
Directors  in each  class are  elected to serve for  three-year  terms and until
their  successors  are elected and  qualified.  Each year,  the directors of one
class stand for  re-election  as their terms of office  expire.  Messrs.  Jones,
Ramsey and  Richard E.  Rainwater  (who is not  standing  for  re-election)  are
designated  as Class  III  directors,  and their  terms of office  expire at the
Annual  Meeting.  Messrs.  Gardner  and  Houghton  are  designated  as  Class  I
directors,   and  their  terms  of  office  expire  at  the  annual  meeting  of
stockholders in 2001. Messrs.  Baroffio,  Sheffield and Stillwell are designated
as Class II directors, and their terms of office expire at the annual meeting of
stockholders  in 2002.  Since the last  annual  meeting of  stockholders,  three
directors of the Company, I. Jon Brumley,  Kenneth A. Hersh and Philip B. Smith,
voluntarily resigned as directors of the Company. None of these resignations was
the result of a  disagreement  with the  Company on any matter  relating  to the
Company's  operations,  policies or  practices.  Mr.  Rainwater has notified the
Board of his  intention  not to stand  for  re-election  to the Board due to his
decision to retire  effective May 17, 2000. Mr.  Brumley  resigned to devote his

                                        3

full  time  and  attention  to his  position  as  President  and  CEO of  Encore

<PAGE>




         The  Board  of  Directors  has  two  standing  committees:  the  "Audit
Committee" and the "Compensation Committee."

         The Audit Committee makes recommendations to the Board of Directors for
selecting the Company's  independent  auditors,  considers the  independence  of
auditors  before engaging them,  reviews with auditors their reports,  discusses
internal  accounting  procedures  and  financial  controls  with  the  Company's
management   and   auditors,   and  may  initiate  and   supervise  any  special
investigations  it deems  necessary.  The  members  of the Audit  Committee  are
Messrs.  Houghton  (Chairman),  Gardner and Jones. The Audit Committee held four
meetings during 1999.

         The  Compensation  Committee  periodically  reviews  the  compensation,
employee  benefit  plans and fringe  benefits  paid to or provided for executive
officers of the  Company and  approves  the annual  salaries  and bonuses of the
Company's  executive  officers.  The members of the  Compensation  Committee are
Messrs.  Ramsey  (Chairman),  Baroffio and Stillwell.  A subcommittee of Messrs.
Ramsey and Baroffio  administer the Long-Term  Incentive Plan. The  Compensation
Committee held five meetings during 1999.

                             MANAGEMENT COMPENSATION

         The Company began  operations upon completion of the merger of Parker &
Parsley and Mesa on August 7, 1997.  Information  about management  compensation
for  periods  before  that  date  refers  to  compensation  that  either  of the
predecessor companies paid.

Compensation of Directors

         Each  non-employee  director receives an annual retainer fee of $50,000
if the director  serves on a committee  and $40,000 if he does not. In addition,
each non-employee  director is reimbursed for travel expenses to attend meetings
of the  Board of  Directors  or its  committees  and an  additional  $2,500  for
services as chairman of a committee.  No additional fees are paid for attendance
at board or committee meetings. Executive officers of the Company do not receive
additional compensation for serving on the Board of Directors.

         Under the Company's Long-Term Incentive Plan (the "Plan"), non-employee
directors  are  eligible to receive  awards in the form of  non-qualified  stock
options, stock appreciation rights,  restricted stock, or performance units. The
Company  uses these  awards  instead of cash to pay its  non-employee  directors
their  annual  retainer  fees.  The Board of Directors  determines  the form (or
combination  of forms) of  consideration  each year,  based on the  economic and
other  circumstances at the time and based on its view of which awards will best
align the interests of the stockholders and the directors.

         In  order  for the  Directors  to  participate  in the  Company's  cost
reduction  program and to tie 100% of their  compensation to the Company's stock
performance,  the  Board of  Directors  determined  to use  non-qualified  stock
options  to pay all of the  non-employee  directors'  annual  fees  for the year
following the Company's 1999 annual stockholders'  meeting. The number of shares
subject to stock options granted to each non-employee director was determined by
dividing the  director's  annual  retainer fee by the value of an option for one
share on May 28, 1999 (the last business day of the month in which the Company's
1999 annual  stockholders'  meeting was held).  The options  have a  fair-market
value  exercise  price,  and the value of each option was  calculated  using the
Black-Scholes  method based on assumptions  provided by the Company's  executive
compensation consulting firm. These options vest 25% each quarter with the first
vesting date on August 31, 1999.

         On May 28, 1999,  each  non-employee  director  received the  following
awards of stock  options to  compensate  him for his annual  retainer  fee (each
stock  option  awarded  has an exercise  price of  $10.875):  Messrs.  Baroffio,
Gardner,  Jones and Stillwell each received  options for 10,184 shares;  Messrs.
Brumley,  Houghton and Ramsey each received  options for 10,693 shares;  and Mr.
Rainwater received an option for 8,147 shares. Mr. Brumley  subsequently retired
as a director of the Company  effective  August 31, 1999,  and  forfeited  stock
options to purchase 8,019 shares.

         Effective  November 18, 1999, each  non-employee  director  received an
award of 30,000  non-qualified stock options at an exercise price of $10.25. One
third of these options vest on May 17, 2000,  one third vest on May 17, 2001 and
the remaining one third vest May 17, 2002. The foregoing stock option awards are

                                        6

not regular, annual awards but were granted to bring the directors' compensation
package to a level  competitive with the director  compensation of the Company's
peer group used for establishing executive compensation.

Compensation of Executive Officers

         The compensation  paid to the Company's  executive  officers  generally
consists of base salaries,  annual bonuses, awards under the Long-Term Incentive
Plan,  contributions to the Company's 401(k)  retirement plan, and miscellaneous
perquisites.  The following table  summarizes the total  compensation  for 1999,
1998, and 1997 awarded to, earned by or paid to the following persons:

     Subject to accelerated lapse in certain circumstances, the ownership of the
     stock vests after one year and transfer restrictions lapse on one- third of
     the shares on each of the first, second and third anniversaries of the date
     of  grant.  The  number of shares of  restricted  stock  awarded  as annual
     bonuses  was  calculated  using the last  closing  sale price of the common
     stock before the date of the award  ($22.375).  Ownership of the restricted
     stock awarded for 1997 vested on September 30, 1998,  due to the triggering
     of a vesting acceleration clause contained in the Long-Term Incentive Plan.

(d)  The restricted stock awarded in 1997 represents grants on August 8, 1997 of
     59,000 shares of common stock to Mr.  Sheffield and 23,000 shares of common
     stock to each of Messrs.  Fagerstone,  Withrow, Dove and Smith with vesting
     restrictions that were to lapse one-half on August 8, 2000, and one-half on
     August 8, 2001. Messrs.  Sheffield,  Fagerstone,  Withrow, Dove and Smith's
     restricted  stock fully vested on September 30, 1998 due to the  triggering
     of a vesting  acceleration  clause contained in the Plan. The values of the
     awards were calculated  using the closing sale price of the common stock of
     $37.875  on  August  7,  1997.  Because  all  vesting  restrictions  on all
     restricted stock heretofore  awarded to each executive  officer have lapsed
     (either  by their  terms or  through  acceleration  upon the  happening  of
     certain events) no executive officer held any shares of restricted stock on
     December 31, 1999.

(e)  For 1999 this column  includes (i)  contributions  to qualified  retirement
     plans  for  Messrs.  Sheffield,  Fagerstone,  Withrow,  Dove  and  Smith of
     $16,000,  $15,814,   $15,922,  $15,894,  and  $15,922  respectively;   (ii)
     contributions  to  the  Company's   non-qualified   deferred   compensation
     retirement plan for Messrs. Sheffield,  Fagerstone, Withrow, Dove and Smith
     of $48,923, $24,750,  $22,933,  $22,500, and $22,933 respectively;  (iii) a
     $1,330 premium with respect to a term life insurance policy for the benefit
     of Mr. Sheffield;  (iv) reimbursement for financial counseling services for
     Messrs. Sheffield and Smith for $3,125 and $507 respectively.

     Long-Term  Incentive Plan. The Plan provides for employee and  non-employee
director  awards  in the  form of  stock  options,  stock  appreciation  rights,
restricted  stock,  and performance  units payable in stock or cash. The maximum
number of shares of common  stock that may be issued  under the Plan is equal to
10% of the total number of shares of common stock  outstanding from time to time
minus the total number of shares of stock subject to  outstanding  awards on the
date of calculation  under any other stock-based plan for employees or directors
of the Company and its subsidiaries. The Plan had 4,275,311 shares available for
additional awards at December 31, 1999.

     Information  about restricted stock awards made under the Plan is set forth
in the Summary  Compensation  Table. No performance units or stock  appreciation
rights have been awarded under the Plan.

     The following table sets forth  information  about stock option grants made

(a)   These  options  were  granted on February  24,  1999,  vest at the rate of
      one-third  each year,  commencing  on the first  anniversary  of the grant
      date,  and  have a term of five  years  from  the  date  of  vesting.  The
      Compensation  Committee  retains  discretion,  subject to plan limits,  to
      modify  the terms of the  options.  In the event of a change in control of
      the Company as defined in the Plan,  the options will  immediately  become
      fully vested and exercisable in full.

(b)   These  options  were  granted  on  August  23,  1999,  vest at the rate of
      one-third each year commencing on the first anniversary of the grant date,
      and have a term of five years from the date of vesting.  The  Compensation
      Committee retains discretion,  subject to plan limits, to modify the terms
      of the  options.  In the event of a change in  control  of the  Company as
      defined in the Plan, the options will immediately  become fully vested and
      exercisable in full.

(c)   The exercise  price per share is equal to the closing  price of the common
      stock on the New York Stock Exchange  composite tape on the day before the
      date of grant.

(d)   The  estimated  grant  date  value of shares in  footnotes  (a) and (b) is
      determined using the  Black-Scholes  model.  The material  assumptions and
      adjustments  incorporated  in the  Black-Scholes  model in estimating  the
      value of the options include the following:

      -  An interest  rate of 6.59% for footnote (a) and 6.51% for footnote (b),
         which represents the interest rate on a U. S. Treasury  security with a
         maturity date corresponding to the option term.

      -  Volatility of 50% for footnote (a) and 50% for footnote (b)  calculated
         using daily  stock  prices for the  120-day  period  prior to the grant
         date.

      No other  adjustments  were made to the model for  non-transferability  or
      risk of forfeiture.  The ultimate values of the options will depend on the
      future  market price of the common  stock,  which cannot be forecast  with
      reasonable  accuracy.  The actual value,  if any, an optionee will realize
      upon  exercise of an option will depend on the excess of the market  value
      of the  common  stock  over the  exercise  price on the date the option is
      exercised.

      The  following  table  sets  forth,  for  each  named  executive  officer,
information  concerning the exercise of stock options during 1999, and the value

(a)   Amounts  were calculated by multiplying the  number of unexercised options
      by  $8.9375,  which was  the closing  sale price  of the  common  stock on
      December 31, 1999, and subtracting the aggregate exercise price.

         Retirement  Plan.  The  Company   provides  a  non-qualified   deferred
compensation retirement plan for officers and key employees of the Company. Each
participant  is allowed to  contribute  up to 25% of base  salary.  The  Company
provides  a  matching  contribution  of 100% of the  participant's  contribution
limited  to the  first  10% of  the  officer's  base  salary  (or 8% of the  key
employee's base salary). The Company matching contribution vests immediately.

         Employee  Investment  Partnerships.  From 1987 through  1991,  Parker &
Parsley   formed   employee   partnership   programs  in  which  Mr.   Sheffield
participated.  In 1992 and 1993 Mr. Sheffield and Mr. Withrow  participated in a
Direct Investment  Partnership formed to invest in all wells drilled by Parker &
Parsley  during  those  years  (except  in  certain   circumstances   where  its
participation would impose additional costs to Parker & Parsley). As of December
31,  1999,  the  aggregate  contributions  that have  been made to the  employee
partnerships  and the Direct  Investment  Partnerships by Mr.  Sheffield and Mr.
Withrow and the  aggregate  distributions  that have been  received by them from
those  partnerships  were as follows:  Mr.  Sheffield  contributed  $734,955 and
received $1,145,680 ($79,555 of which was received during 1999); and Mr. Withrow
contributed $142,625 and received $151,437 ($13,206 of which was received during
1999).

         Severance  Agreements.  On August 8, 1997,  the  Company  entered  into
severance  agreements  with its  officers.  Salaries  and bonuses are set by the
Compensation  Committee  independent of these  agreements,  and the Compensation
Committee can increase or reduce base salaries at its discretion.

         Either  the  Company  or  the  officer  may   terminate  the  officer's
employment  under the severance  agreement at any time. The Company must pay the
officer an amount equal to one year's base salary if the officer's employment is
terminated because of death, disability, or normal retirement.  The Company must
pay the officer an amount  equal to one year's base salary and  continue  health
insurance for the officer's  family for one year if the Company  terminates  the
officer's  employment without cause or if the officer terminates  employment for
good reason, which is when reductions in the officer's base annual salary exceed
specified limits or when the officer's  responsibilities have been significantly
reduced.  If within  one year  after a change in  control  of the  Company,  the
Company  terminates  the officer  without  cause,  or if the officer  terminates
employment for good reason,  the Company must pay the officer an amount equal to
2.99 times the sum of the  officer's  base salary plus target bonus for the year
and continue  health  insurance  for the  officer's  family for one year. If the
officer terminates employment with the Company without reason between six months
and one year after a change in  control,  or at any time within one year after a
change in control if the officer is required to move,  then the Company must pay
the  officer  one year's  base  salary and  continue  health  insurance  for the
officer's family for one year. Officers are also entitled to additional payments
for certain tax  liabilities  that may apply to severance  payments  following a
change in control.

        Indemnification Agreements. The Company has entered into indemnification
agreements  with  each  of its  directors  and  officers,  including  the  named
executive  officers.  Those  agreements  require  the Company to  indemnify  the
directors and officers to the fullest extent  permitted by the Delaware  General
Corporation  Law and to advance  expenses  in  connection  with  certain  claims
against  directors  and  officers.  The  Company  expects to enter into  similar
agreements  with persons  selected to be  directors  and officers in the future.
Each  indemnification  agreement also provides that, upon a potential  change in
control of the Company and if the  indemnified  director or officer so requests,
the Company will create a trust for the benefit of the  indemnified  director or
officer in an amount  sufficient to satisfy payment of all liabilities and suits
against which the Company has indemnified the director or officer.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         Mr. Robert L.  Stillwell is a member of the  Compensation Committee and
is a partner of Baker & Botts,  L.L.P., which provided limited legal services to
the Company  during  1999.  The dollar  amount of fees that the Company  paid to
Baker & Botts,  L.L.P.  during the most recent  fiscal year of that law firm did
not exceed 5% of that firm's gross revenues. Mr. Stillwell does not serve on the
sub-committee  of the  Compensation  Committee  that  administers  the Company's
Long-Term Incentive Plan.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         The Compensation  Committee of the Board of Directors (the "Committee")
submits the following report with respect to the executive  compensation program
of the Company.

Compensation Principles and Philosophy

         The  overriding  responsibility  of the  Committee  is to maintain  the
Company's  executive  compensation  program so that it  attracts  and  retains a
capable and highly motivated senior  management team and aligns the compensation
of the  Company's  executives  with the  Company's  strategic  business  plan to
increase  stockholder  value.  During 1999, the Committee  retained an executive
compensation  consulting  firm ("Hewitt  Associates") to assist and advise it in
its efforts to establish and administer  fair and competitive  compensation  and
incentive policies.  These policies emphasize variable  compensation,  structure
the annual bonus and long-term  incentive awards to be a significant  portion of
an  executive's  total  compensation  and result in total  compensation  that is
reflective of Company  performance.  Stock awards will continue to be emphasized
as part of each  executive's  compensation  package  to  align  stockholder  and
executive interests.  Other critical elements of the Company's  compensation and
incentive policies provide for:

         o   Base  salaries  at or  slightly  above  median  levels  compared to
             industry survey information and peer group proxy analysis.

         o   Annual  bonuses  that are  based  on both  individual  and  Company
             performance.

         o   Long-term incentive award levels that are above median.

         o   Significant stock ownership by management.

         To support the commitment to significant stock ownership, the Company's
current stock ownership guidelines are as follows:

         o   Non-employee directors - stock  value equal to at least three times
             each director's annual retainer fee.

         o   Chairman of the  Board and  Chief  Executive  Officer - stock value
             equal to at least five times base salary.

         In  determining   compliance  with  these  guidelines,   the  Committee
considers its expectations of the long term value of the Company's stock and the
current trading levels.  Mr.  Sheffield and all Directors are in compliance with
the ownership guidelines.

<PAGE>


         The  Omnibus  Budget  Reconciliation  Act  of  1993  ("OBRA93")  placed
restrictions  on the  deductibility  of  executive  compensation  paid by public
companies.  Under the  restrictions  that began to apply in 1994, the Company is
not able to deduct  compensation paid to any of the named executive  officers in
excess  of  $1,000,000   unless  the   compensation   meets  the  definition  of
"performance  based  compensation" in the legislation.  Non-deductibility  could
result in additional tax costs to the Company. While the Committee cannot assess
with  certainty  how the  Company's  compensation  program  will  ultimately  be
affected by OBRA93, the Committee  generally tries to preserve the deductibility
of all  executive  compensation  if it can do so  without  interfering  with the
Company's  ability to attract  and retain  capable and highly  motivated  senior
management.  However,  in order to  induce  certain  executive  officers  of the
Company to  relocate to the  Company's  principal  executive  offices in Irving,
Texas,  after the merger of Parker & Parsley and Mesa in 1997,  the Company made
certain relocation  reimbursement payments to such officers, which payments were
not wholly  deductible  by the  Company  because of the  compensation  limits of
OBRA93.

Elements of Compensation

         The elements of the compensation program the Committee  administers for
executive  officers,  including  the Chief  Executive  Officer,  consist of base
salaries,  annual bonuses,  awards made under the Company's Long- Term Incentive
Plan (the  "Plan"),  contributions  to the  Company's  401(k)  retirement  plan,
contributions  to the  Company's  deferred  compensation  retirement  plan,  and
miscellaneous   perquisites.   Base  salaries,   annual  bonuses  and  long-term
incentives are discussed separately below;  however, the Committee considers the
aggregate  remuneration of executives when evaluating the executive compensation
program.

         Base  Salaries.  An  executive's  base  salary  is  viewed  as a  fixed
component of total  compensation  that should be  competitive  with companies of
similar size and  business to the  Company.  The  Committee  has  targeted  base
salaries at or slightly above the median level for companies of similar size and
business  to the  Company.  The  Committee  evaluates  the base  salaries of the
Company's executive officers on the basis of competitive base salary survey data
provided  by its  consultant  and  consideration  of each  officer's  duties and
responsibilities.  The Committee views the named  executives below the CEO level
as a team with diverse  duties but with similar  authority  and  responsibility.
Hewitt  Associates  provides  base  salary  survey  data on the  majority of the
Company's  peer  group  companies,  a  group  of  independent   exploration  and
production companies with similar asset, revenue and capital investment profiles
as the Company. While the peer group provided by Hewitt Associates includes some
of the  members  of the Dow Jones  Oil-Secondary  Index  (the "DJ  Oil-Secondary
Group") reflected in the performance graph set forth under "Company Performance"
below,  it does not include all of the companies in that peer group and includes
other companies with which the Company  competes.  The Committee  determines the
base salary for all named executives,  including Mr.  Sheffield,  using the same
methodology.

         Due to adverse economic conditions the oil and gas industry experienced
during 1998, and the desire to reduce the Company's 1999 cost structure during a
year of expected  low  commodity  prices,  Mr.  Sheffield  reduced his 1999 base
salary by 20% to $480,000, and the other named executive officers' base salaries
were reduced by 10%. For 1999, Mr.  Sheffield's and the other named  executives'
base salaries were significantly less than the 50th percentile,  even though the
Company normally  targets the 50th percentile  level for base salary.  Effective
January 1, 2000,  the 1999 salary  reduction  program  expired and base salaries
were restored to the 1998 levels.  Mr.  Sheffield's  base salary was restored to
$600,000. For 2000, Hewitt Associates determined that merely returning the named
executive officer's salary to the 1998 level resulted in base salaries below the
Company's  targeted  50th  percentile  level.  Effective  January 1,  2000,  Mr.
Sheffield's  base salary was increased to $638,000,  which Hewitt has identified
as the 50th percentile level. The other named executive  officers' base salaries
were also  restored to the 1998 levels and increased to  approximately  the 50th
percentile level.

         Annual  Bonuses.  Each year the Committee  sets a target bonus for each
executive  based on the range of the peer  group's  bonus  targets.  To maintain
internal  equity,  the  level of  responsibility,  scope and  complexity  of the
executive's position are considered. Awards may vary from 50% to 150% of target.
For 2000,  the  Committee  reduced the target bonus  opportunity  for each named
executive by 5%. Mr.  Sheffield's  new target  bonus will be slightly  below the
50th percentile,  and the target bonus for the other named executives will be at
approximately the 50th percentile.

         For 1999,  the  Committee  awarded  Mr.  Sheffield  and the other named
executives a cash bonus of 75% of target. In addition to the annual bonus award,
the Committee  approved the forgiveness of a $113,204  Company loan to Mr. Dove.
As part of his initial  hiring  package,  Mr. Dove  received a restricted  stock
award  which  vested in August,  1997 due to the merger of Parker & Parsley  and
MESA.  The Company funded the tax  liability on the vested stock  through a loan

                                       11


<PAGE>



because the United  States  Securities  and Exchange  Commission  ("SEC")  rules
prevented  Mr.  Dove  from  selling  the  stock  without  incurring  substantial
penalties.  In February 1999 the  Committee  forgave the loan when it determined
the current value of the award was less than the tax liability  triggered by the
merger. In awarding 1999 bonuses,  the Committee reviewed the following criteria
that are important to the success of the Company's business plan.

      -  Growth of Cash Flow per Share     -  Operating Cost per BOE
      -  Debt/Book                         -  Reserve Replacement
      -  Growth of Net Value per Share     -  Finding & Development Cost per BOE
      -  Production Growth                 -  Debt/BOE

         In determining the named executive  officers' annual bonus awards,  the
Committee also evaluated the Company's stock performance in relation to its peer
group. The Committee did not employ a formula, specific targets or predetermined
weighting  of the above  financial  or  operational  performance  criteria.  The
Committee  also evaluates  Company  performance in light of oil and gas industry
fundamentals and assesses how effectively management adapts to changing industry
conditions  and  opportunities  during  the year.  The  Committee  observes  and
evaluates the individual  performance of executive officers through the year and
discusses the performance of these key executives with Mr. Sheffield.

         Long-term  Incentives.  A  significant  portion of the named  executive
officers' total compensation is comprised of long-term  incentive awards,  which
are intended to align executive  management's interests in long- term growth and
success more  closely with the  interests  of the  Company's  stockholders.  The
Committee has  determined  that annual stock option awards should be the primary
method to award  long-term  incentives.  To provide an averaging  effect for the
stock option exercise prices, the Committee has elected to make semiannual stock
option awards of approximately 50% of annual grant levels.

         The number of options  granted to Mr.  Sheffield in 1999 was determined
by a comparison of option grants made to the CEO's of peer group companies.  The
other named  executive  officers were  reviewed as a team.  The level of options
awarded to each named  executive was  determined by comparing  awards granted to
peer company executives  holding similar  positions,  and their individual award
levels were averaged to determine the actual  grants.  The award levels were not
influenced by the stock holdings of the executives. The Company has historically
held to the philosophy of awarding  long-term  incentives  that are above market
averages.  Hewitt  Associates  concluded  the 1999 stock  option  awards for the
Company's named executive officers,  including Mr. Sheffield,  are now below the
50th  percentile  among the survey group.  For 1999,  Mr.  Sheffield was awarded
90,000  stock  options,  which,  according  to  Hewitt  Associates,  placed  Mr.
Sheffield  below the 50th  percentile for long-term  incentive  awards for chief
executive officers among the survey group.

         In December 1998, the Company  received  information that an investment
fund  group had  acquired  beneficial  ownership  of more than 20% of the common
stock.  Pursuant to the provisions of the Plan, if a third party acquires 20% or
more of the common stock, certain change in control provisions are triggered. In
December  1998, the Committee  determined  that a change in control had occurred
under the provisions of the Plan,  effective  September 30, 1998.  Consequently,
all stock option  awards  granted  under the Plan from  inception in August 1997
through  September 30, 1998, were  immediately  vested,  and the restrictions on
restricted stock awards were removed.  The Plan has been amended to increase the
third party ownership to 40% to trigger the change in control provisions.

         In summary,  the Company  believes a  significant  portion of executive
compensation  should be variable and  performance-based  so that an  executive's
total  compensation is linked to the performance of the individual,  the Company
and its stock  price.  The  majority  of the  named  executive  officers'  total
compensation  is  variable,  at-risk  compensation.  This  structure  allows the
Company to  administer  overall  compensation  that rises or falls  based on the
Company's performance and to maintain a balance between the Company's short-term
and long-term objectives.

                               COMPANY PERFORMANCE

         The following  graph and chart compare the Company's  cumulative  total
stockholder  return on common stock during the period from  December 31, 1994 to
December 31, 1999,  with  cumulative  total  stockholder  return during the same
period for the DJ  Oil-Secondary  Group and the Standard & Poor's 500 Index. The
Company's  cumulative total stockholder  return for the period from December 31,
1994 to December 31, 1999 consists of Parker & Parsley's operating results prior
to August 8, 1997 and the Company's  operating results beginning August 8, 1997.
After the merger of Parker & Parsley and Mesa in 1997,  the Company  began using
the DJ Oil-Secondary  to compare its performance  because several members of the
Company's  peer  group use that  index to  simplify  the  evaluation  of company
performance and because the DJ  Oil-Secondary  is more readily  available to the
public for comparison purposes.  The graph and chart show the value, at December
31 in each of 1995,  1996,  1997, 1998 and 1999 of $100 invested at December 31,
1994, and assume the reinvestment of all dividends.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

          The  executive  officers and  directors of the Company are required to
file reports with the SEC, and with the various Canadian  provincial  securities
commissions  (the "Canadian  Commissions"),  disclosing the amount and nature of
their  beneficial  ownership  in  common  stock,  as  well  as  changes  in that
ownership.  Pursuant to applicable Canadian policies, the executive officers and
directors  of the Company are  exempted  from filing  reports  with the Canadian
Commissions,  provided  that they timely  file all reports  required to be filed
with the SEC.

          Based solely on its review of reports and written representations that
the Company has received,  the Company  believes that all required  reports were
filed on time for 1999.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

          The Company,  through its wholly-owned  subsidiaries,  has in the past
sponsored certain  affiliated  partnerships,  including 22 public and 22 private
drilling  partnerships and three public income  partnerships,  all of which were
formed  primarily for the purpose of drilling and completing  wells or acquiring
producing properties. In accordance with the terms of the partnership agreements
and the related tax partnership agreements of the affiliated  partnerships,  the
Company  participated  in the  activities  of the  sponsored  partnerships  on a
promoted basis. In 1992, the Company discontinued  sponsoring public and private
oil and gas development drilling and income partnerships.

          During  each of  1994,  1993 and  1992,  the  Company  formed a Direct
Investment  Partnership for the purpose of permitting  selected key employees to
invest directly,  on an unpromoted basis, in wells that the Company drills.  The
partners in the Direct Investment Partnerships formed in 1994, 1993 and 1992 pay
and receive approximately .337%, 1.5375% and 1.865%, respectively,  of the costs
and revenues  attributable to the Company's  interest in the wells in which each
such Direct Investment  Partnership  participates.  The Company discontinued the
formation of Direct Investment Partnerships in 1995.

          The Company, through a wholly-owned subsidiary,  serves as operator of
properties  in  which  it and its  affiliated  partnerships  have  an  interest.
Accordingly,  the  Company  receives  producing  well  overhead,  drilling  well
overhead  and  other  fees  related  to the  operation  of the  properties.  The
affiliated  partnerships also reimburse the Company for their allocated share of
general and administrative charges.

          Effective  January 1, 1999, the Company entered into an agreement with
Rainwater,  Inc., the former general  partner of DNR that Mr.  Rainwater  wholly
owns,  modifying  certain terms of a prior agreement between DNR and Mesa, which
was assumed by the Company  upon  consummation  of the merger  between  Parker &
Parsley and Mesa.  Pursuant to the terms of this  agreement,  as  modified,  the
Company will pay Rainwater, Inc. $300,000 per year and reimburse Rainwater, Inc.
for certain expenses in consideration of the provision of certain consulting and
financial  analysis  services  to  the  Company  by  Rainwater,   Inc.  and  its
representatives.

          On June 29, 1999,  the Company  completed  the sale of certain  United
States oil and gas producing  properties,  gas plants and other assets primarily
located in the Gulf Coast, Mid Continent and Permian Basin to Prize Energy Corp.
("Prize"). The sale of these assets was initiated through an auction process.

          The Board of  Directors of  Prize  includes  Mr. Philip P. Smith,  its
Chief  Executive  Officer,  Mr.  Kenneth A.  Hersh,  and Mr.  Lon C.  Kile,  its
President and Chief Operating Officer.  Mr. Hersh,  through his association with
Natural Gas Partners V, L.P.,  owned or controlled  approximately  88% of Prize.
Messrs. Smith and Kile owned or controlled  approximately 10.5% and .5% of Prize
respectively.  Because  Mr.  Smith and Mr.  Hersh  were  members of the Board of
Directors  of the Company and Mr. Kile was an  Executive  Vice  President of the
Company prior to initiating the auction process, supervision of the sale process
was placed under the direction of a special independent  committee (comprised of
outside directors  unrelated to Prize) of the Company's Board of Directors.  The
independent  committee  reviewed  and  considered  all offers  presented  to the
Company for the  purchase of the assets  acquired by Prize.  The Prize offer was
approved by the special independent committee as being the best offer presented.
Following  approval  of the Prize offer by the  special  independent  committee,
Messrs. Smith, Hersh and Kile resigned their positions with the Company.

          In accordance with the terms of the Prize purchase and sale agreement,
the Company  received net sales proceeds of $245.0 million,  comprised of $215.0
million of cash and 2,307.693 shares of six percent convertible  preferred stock
having a liquidation  preference and fair value of $30.0 million. As a result of
Prize merging with Vista Energy  Resources,  Inc.,  the Company's  investment in
Prize's six percent  convertible  preferred  stock was  exchanged  for 4,018,161
shares  of  Prize  Series  A  convertible   preferred  stock  ("Prize  Series  A
Preferred").  The Prize  Series A  Preferred  provides  for six  percent  annual
dividend  payments,  payable  quarterly  in  additional  equity  shares of Prize
through 2001.  Subsequent to 2001,  Prize has the option of paying the quarterly
dividends on the Prize Series A Preferred in equity  shares or cash.  Each share
of the Prize Series A Preferred may, at the option of the Company,  be converted
into  one  share  of  Prize  common  stock,  subject  to  certain  anti-dilution
adjustments.

          The Company has entered into an agreement with Prize to sell effective
March 31, 2000,  1,380,446  shares of the Prize Series A Preferred back to Prize
for  $18,636,021.  Pioneer and Prize have also  agreed to convert the  remaining
shares of the Prize  Series A  Preferred  to  2,637,715  shares of Prize  common

stock. If these transactions are completed as planned,  the Company's  ownership
of outstanding Prize common and preferred voting shares would decline from 27.4%
to 19.9% and Mr.  Sheffield and Mr.  Withrow will resign from the Prize Board of
Directors.

          In February  1999, the Company,  after approval from the  Compensation
Committee,  forgave an August,  1997 loan to Mr. Dove in the amount of $113,204,
which funded the tax liability resulting from vesting of his restricted stock in
August 1997 in the merger of Parker & Parsley and MESA.

                              STOCKHOLDER PROPOSALS

          Any  stockholder  of the Company who desires to submit a proposal  for
action at the Company's  annual meeting of  stockholders  for 2001 and wishes to
have such proposal (a "Rule 14a-8  Proposal")  included in the  Company's  proxy
materials,  must submit such Rule 14a-8 Proposal to the Company at its principal
executive  offices no later than December 11, 2000,  unless the Company notifies
the  stockholders  otherwise.  Only those Rule 14a-8  Proposals  that are timely
received by the Company and proper for stockholder action (and otherwise proper)
will be included in the Company's proxy materials.

          Any  stockholder  of the Company who desires to submit a proposal  for
action at the annual meeting of  stockholders in 2001, but does not wish to have
such proposal (a "Non-Rule  14a-8  Proposal")  included in the  Company's  proxy
materials,  must  submit  such  Non-Rule  14a-8  Proposal  to the Company at its
principal  executive offices no later than February 24, 2001, unless the Company
notifies  the  stockholders  otherwise.  If a  Non-Rule  14a-8  Proposal  is not
received by the Company on or before February 24, 2001, then the Company intends
to exercise its  discretionary  voting  authority  with respect to such Non-Rule
14a-8 Proposal.  "Discretionary voting authority" is the ability to vote proxies
that  stockholders  have  executed and  returned to the Company,  on matters not
specifically   reflected  in  the  Company's  proxy  materials,   and  on  which
stockholders have not had an opportunity to vote by proxy.

          Written  requests for inclusion of any stockholder  proposal should be
addressed  to Corporate  Secretary,  Pioneer  Natural  Resources  Company,  1400
Williams Square West, 5205 North O'Connor  Boulevard,  Irving,  Texas 75039. The
Company  suggests  that any such  proposal  be sent by  certified  mail,  return
receipt requested.

          The Board of  Directors  will  consider  any  nominee  recommended  by
stockholders  for election at the annual meeting of  stockholders  to be held in
2001 if that  nomination  is  submitted  in writing,  not later than January 10,
2001, to Corporate Secretary,  Pioneer Natural Resources Company,  1400 Williams
Square West, 5205 North O'Connor Boulevard, Irving, Texas 75039. Each submission
must  include a statement  of the  qualifications  of the  nominee,  a notarized
consent  signed by the nominee  evidencing a willingness to serve as a director,
if elected,  and a commitment by the nominee to meet  personally with members of
the Board of Directors.

                             SOLICITATION OF PROXIES

          Solicitation  of  Proxies  may be made by  mail,  personal  interview,
telephone  or  telegraph by  officers,  directors  and regular  employees of the
Company.  The Company may also request banking  institutions,  brokerage  firms,
custodians,  nominees and  fiduciaries to forward  solicitation  material to the
beneficial  owners of the common  stock that those  companies or persons hold of
record, and the Company will reimburse the forwarding expenses. In addition, the
Company has retained D.F. King & Co., Inc. to assist in  solicitation  for a fee
estimated not to exceed $7,500. The Company will bear all costs of solicitation.

                                STOCKHOLDER LIST

          In accordance with the Delaware  General  Corporation Law, the Company
will  maintain  at its  corporate  offices  in  Irving,  Texas,  a  list  of the
stockholders  entitled to vote at the Annual  Meeting.  The list will be open to
the examination of any stockholder,  for purposes germane to the Annual Meeting,
during ordinary business hours for 10 days before the Annual Meeting.

            Information Statement for Holders of Exchangeable Shares
                                       of
                      Pioneer Natural Resources Canada Inc.

          The enclosed  Proxy  Statement  and related  materials  pertaining  to
Pioneer Natural Resources Company  ("Pioneer") have been provided to all holders
of  Exchangeable  Shares of Pioneer  Natural  Resources  Canada  Inc.  ("Pioneer
Canada") for the  purposes of  Pioneer's  annual  meeting of  stockholders  (the
"Annual Meeting") to be held on May 18, 2000 at 9:00 a.m. (Dallas,  Texas time),
in the Miro Room at the Wyndham Anatole Hotel,  Dallas, Texas 75207. As a holder
of Exchangeable  Shares,  you are entitled to dividend and other rights designed
to be equivalent to the attributes of the Common Stock of Pioneer, including the
right,  through a Voting and Exchange Trust Agreement (the "Voting  Agreement"),
to  attend  and to vote at the  Annual  Meeting.  Given  the  attributes  of the
Exchangeable  Shares,  you will not  receive a Notice,  Information  Circular or
Proxy for an annual  meeting  of  shareholders  of  Pioneer  Canada,  nor will a
meeting of holders of Exchangeable Shares be held.

Exercise of Voting Rights

          Pursuant to the Voting  Agreement,  Montreal  Trust  Company of Canada
(the  "Trustee")  holds one share of special  preferred  voting stock of Pioneer
(the "Voting  Share") for the benefit of the holders (other than Pioneer and its
subsidiaries) of the Exchangeable  Shares.  The Voting Share carries a number of
votes,  exercisable at any meeting at which Pioneer stockholders are entitled to
vote  (including  the  Annual  Meeting),  equal  to the  number  of  outstanding
Exchangeable  Shares  (other than shares held by Pioneer and its  subsidiaries).
You are entitled to instruct  the Trustee to exercise one of the votes  attached
to the  Voting  Share  for each  Exchangeable  Share  you  hold,  or to grant to
Pioneer's  management  a proxy to  exercise  such votes in  accordance  with the
enclosed Proxy Statement.  Alternatively,  you may instruct the Trustee to grant
to you or your  designee  a proxy to attend the Annual  Meeting  and  personally
exercise your voting  rights.  For this  purpose,  the Trustee has furnished (or
caused  Pioneer to furnish) the enclosed  Proxy  Statement  and certain  related
materials to you as a holder of Exchangeable Shares.

          To instruct  the  Trustee as to how you want to  exercise  your voting
rights, you must complete,  sign, date and return the enclosed form of direction
(the "Direction") to the Trustee by no later than 12:00 p.m. noon (Calgary time)
on May 16, 2000 (the "Due  Time").  If the Trustee  does not receive  your fully
completed  Direction by the Due Time,  your voting rights will not be exercised.
You may revoke or amend your  instructions  to the Trustee (as indicated in your
Direction)  at any time up to and  including  the Due Time by  delivering to the
Trustee a written notice of revocation or by completing,  signing and delivering
to the  Trustee a new  Direction  bearing a later  date.  You may also revoke or
amend  your  instructions  in person at the  Annual  Meeting  prior to 9:00 a.m.
(Dallas,  Texas time) on May 18,  2000,  by  submitting  a written  amendment or
revocation of your  instructions and presenting  satisfactory  identification to
the  Trustee's  representatives  at the Annual  Meeting.  In either  case,  your
instructions of the later date will be binding on the Trustee.

General

          Pioneer Canada and certain of the insiders  thereof have been exempted
from certain disclosure and insider trading obligations  prescribed by otherwise
applicable  Canadian  securities  legislation  pursuant to discretionary  orders
granted by each of the provincial securities commissions in Canada.  Pursuant to
such orders, Pioneer Canada is not required to prepare and file annual proxy and
related documentation,  quarterly reports, certain material change reports or an
