persons  will also be  authorized  to vote your  shares to  adjourn  the  Annual
Meeting  from  time to time  and to vote  your  shares  at any  adjournments  or
postponements of the Annual 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.  See "Internet  Voting"
below.

     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,  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 7, 2004.

                                QUORUM AND VOTING

     Voting Stock.  The Company has one  outstanding  class of  securities  that
entitles  holders to vote  generally at meetings of the Company's  stockholders:
common stock, par value $.01 per share.  Each share of common stock  outstanding
on the record date is entitled to one vote.

     Record Date. The record date for stockholders  entitled to notice of and to
vote at the Annual  Meeting is the close of business on March 17,  2004.  At the
record date, 120,024,319 shares of common stock were outstanding and entitled to
be voted at the Annual Meeting.

     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

                                        3





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 three 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 individuals for election
as Class I  Directors  of the  Company  with their  terms to expire in 2007 when
their successors are elected and qualified:

                               R. Hartwell Gardner
                                James L. Houghton
                                 Linda K. Lawson

     Messrs.  Gardner and  Houghton  and Mrs.  Lawson are  currently  serving as
Directors of the Company.  Their  biographical  information  is contained in the
"Directors and Executive Officers" section below.

     The Board of  Directors  has no reason to believe  that any 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

     The Charter of the  Company's  Audit  Committee  of the Board of  Directors
requires that the Audit  Committee  review and pre-approve the plan and scope of
Ernst & Young  LLP  audit,  audit-related,  tax and  other  services.  The Audit
Committee  pre-approved  100 percent of the  services  provided by Ernst & Young
LLP.

     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 audit  report of Ernst & Young LLP on the  Company's  annual  financial
statements  for 2003,  2002 and 2001 did not  contain  an  adverse  opinion or a
disclaimer  of opinion and was not  qualified or modified as to  uncertainty  or
audit scope.

     In connection with the audits of the Company's annual financial  statements
for 2003, 2002 and 2001, 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 audit report.

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

                             MANAGEMENT COMPENSATION

Compensation of Directors

     For 2003, each  non-employee  director received an annual base retainer fee
of $40,000 and an annual fee of $10,000  for service on one or more  committees.
Audit Committee  members received an additional  $7,500 annual fee. Dr. Baroffio
in his role as  geosciences  advisor  to the  Board  of  Directors  received  an
additional  $7,500  annual fee, the lead  director and the chairman of the Audit
Committee  each  received an additional  $7,500  annual fee and other  committee
chairmen received an additional $2,500 annual fee. Each non-employee director is
also reimbursed for travel expenses to attend meetings of the Board of Directors
or its  committees.  No  additional  fees are paid  for  attendance  at Board of
Directors or committee meetings.  The Company's Chief Executive Officer does not
receive additional compensation for serving on the Board of Directors.

                                        9






     For 2004, the lead director's  additional fee will be increased from $7,500
to $15,000 and each director,  following their initial three years of service as
a director,  in addition to their  annual base  retainer  fee,  will  receive an
annual equity award of $60,000  equivalent  value.  For 2004,  the annual equity
award will be in the form of restricted stock.

     Under the Company's  Long-Term Incentive Plan,  non-employee  directors are
eligible to receive their fees in the form of stock options,  stock appreciation
rights,  restricted stock or performance units. The Company can use these awards
instead of cash to pay its  non-employee  directors  all or part of their annual
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.  For the year following the 2004 Annual Meeting,
the Board of Directors has determined that  non-employee  directors can elect to
receive their annual fees 100 percent in cash or restricted  stock or 50 percent
cash and 50 percent restricted stock.

     For 2003, the non-employee  directors were given a choice to be compensated
for their  annual  directors'  fees in either  (i) 100  percent  cash,  (ii) 100
percent  stock  options,  (iii)  100  percent  restricted  stock or (iv) a 50/50
combination  of any  thereof.  Messrs.  Baroffio,  Jones,  Ramsey,  Houghton and
Solberg and Mrs. Lawson elected 100 percent cash compensation;  Messrs.  Gardner
and Buchanan elected to receive 100 percent of their  compensation in restricted
stock.  The  number  of  shares  granted  to  non-employee   directors  electing
restricted  stock was determined by dividing the  director's  fees elected to be
paid by restricted  stock by the closing price of one share of the Company stock
on May 14, 2003 (the last closing sale price before the date of the grant).  The
restricted  stock grants  vested 25 percent each quarter with the first  vesting
date on August 15, 2003. Mr. Buchanan received a restricted stock grant of 2,112
shares to  compensate  him for 100  percent of his annual  fees and Mr.  Gardner
received a  restricted  stock grant of 2,313  shares to  compensate  him for 100
percent of his annual fees.

     Each  non-employee  director,  upon  commencement  of initial  service as a
director, receives $125,000 of restricted stock. The price used to calculate the
number of shares to be granted is based on the  closing  stock  price on the day
prior to the day the director is elected to serve on the Board of Directors. The
shares granted are subject to vesting and transfer  restrictions that lapse with
respect  to  one-third  of the  shares  each year  following  the  grant  over a
three-year   period.  The  vesting  of  ownership  and  the  lapse  of  transfer
restrictions  may be  accelerated  in the  event  of the  death,  disability  or
retirement of the director or a change in control of the Company. Each recipient
is required to make an election  under the Internal  Revenue Code to include the
value of the restricted  stock in the  recipient's  income in the year of grant.
The Company  agrees to provide a cash award to the  non-employee  director in an
amount  sufficient to pay the federal income taxes due with respect to the grant
and such cash payment.

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,  contributions to
the  Company's   deferred   compensation   retirement  plan  and   miscellaneous
perquisites.  The following table  summarizes the total  compensation  for 2003,
2002 and 2001 awarded to, earned by or paid to the following persons:

(b)  These  options  were  granted  on  August  19,  2003,  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 date of vesting.  The  Compensation  and
     Management  Development  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 as reported by the New York Stock Exchange on the day before the date
     of grant.
(d)  The  estimated  grant date present 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 included the following:
     o    An interest rate of 3.10 percent for footnote (a) and 3.08 percent for
          footnote (b),  which represents the interest  rate on a  U.S. Treasury
          security  with a  maturity date  corresponding to  the expected option
          term.
     o    Volatility  of 37.6  percent for  footnote  (a)  and  33.6 percent for
          footnote (b) calculated using the lesser of (i) daily stock prices for
          the 120-day period prior to the grant date or (ii) 50 percent.
     No other adjustments were made to the model for  nontransferability or risk
     of forfeiture. The ultimate values of the options will depend on the future
     market price of the Company's  common stock,  which cannot be forecast with
     reasonable  accuracy.  The actual  value,  if any, an optionee will realize
     upon  exercise of the option will depend on the excess of the market  value
     of the  Company's  common  stock  over the  exercise  price on the date the
     option is exercised.

(a)  Amounts were calculated by multiplying the number of unexercised options by
     $31.93,  which  was the  closing  price of the  Company's  common  stock on
     December 31, 2003, and subtracting the aggregate  exercise price, which was
     determined  by  multiplying  the  unexercised  options by their  respective
     exercise prices and summing the result.



     Retirement Plan. The Company provides a 401(k) retirement plan but does not
provide  a  defined  benefit  retirement  plan  or a  restoration  plan.  Hewitt
Associates advised the Company that it was not providing competitive  retirement
benefits  for its  officers  by  offering  only a 401(k)  plan.  To  maintain  a
competitive  position,   the  Company  also  provides  a  nonqualified  deferred
compensation  retirement plan for officers of the Company.  Each  participant is
allowed to  contribute up to 25 percent of base salary and 100 percent of annual
bonus payments.  The Company provides a matching  contribution of 100 percent of
the participant's  contribution limited to the first 10 percent of the officer's
base salary. The Company's matching contribution vests immediately.

     Severance  Agreements.  The Company has entered into  severance  agreements
with  its  officers.  Salaries  and  bonuses  are  set by the  Compensation  and
Management  Development  Committee  independent  of  these  agreements  and  the
Compensation  and Management  Development  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 three years. 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.

                                       13





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 AND MANAGEMENT DEVELOPMENT COMMITTEE
                      INTERLOCKS AND INSIDER PARTICIPATION

     During  2003,  no member of the  Compensation  and  Management  Development
Committee also served as an executive officer of the Company. During 2003, there
were no Compensation and Management  Development Committee interlocks with other
companies.

                COMPENSATION AND MANAGEMENT DEVELOPMENT COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION

     The  Compensation  and  Management  Development  Committee  of the Board of
Directors   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 2003, the committee  retained  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  and structure  the annual bonus and long-term  incentive
awards to be a significant  portion of an executive's total compensation so that
total  compensation  is  reflective  of  the  executive's  performance  and  the
Company's  performance.  Beginning in 2004, the Committee  elected to change the
long-term  incentive  awards from a combination  of stock options and restricted
stock to a  performance-based  restricted  stock  program to  further  emphasize
performance and alignment of stockholder and executive interests.  The committee
has adopted a policy of not repricing stock options and incorporated that policy
into the  Plan.  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  target  bonus  levels  slightly  above median with payouts that are
     based on both individual and Company performance.

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

o    Significant stock ownership by directors and the Chief Executive Officer.

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

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

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

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

                                       14





     The  Omnibus  Budget   Reconciliation   Act  of  1993   ("OBRA93")   placed
restrictions  on the  deductibility  of  executive  compensation  paid by public
companies.   Under  the  restrictions,   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. Nondeductibility 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.

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 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 similar in terms of
business strategy to the Company. The committee has targeted base salaries at or
slightly  above the median level for companies of similar  business  strategy 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  Hewitt   Associates  and   consideration   of  each  officer's   duties  and
responsibilities.  The committee views the executives  below the Chief Executive
Officer  level as a team with  diverse  duties but with  similar  authority  and
responsibility.  Hewitt Associates  historically has provided 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  U.S.  Oil
Companies,  Secondary  Index (the "DJ  Secondary  Oil Index")  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 executives, including Mr. Sheffield, using the same methodology.

     For 2004, Mr. Sheffield's annual base salary was increased from $700,000 to
$775,000.  Mr.  Sheffield  elected to take the  equivalence of the amount of the
increase ($75,000) in shares of the Company's stock. Hewitt Associates indicated
Mr.  Sheffield's  annual base salary is slightly above the 50th percentile.  The
base salary of one other named executive  officer was increased for 2004 but the
other  named  executive  officer's  base  salaries  were not  increased.  Hewitt
Associates  advised that their 2004 base  salaries,  as a group,  continue to be
slightly above the median.

     Annual Bonuses. Each year the committee establishes a target bonus for each
executive  based on the target  bonus  median  levels of  executives  in similar
positions at peer group companies.  To maintain  internal  equity,  the level of
responsibility, scope and complexity of the executive's position are considered.
The range of awards for the annual  incentive bonus plan can range from 0 to 200
percent of target.  The 2004 target bonus levels for Mr. Sheffield and one other
named executive increased to reflect competitive market conditions; however, the
target bonus levels for the other named  executive  officers did not change from
the 2003 target bonus levels.  The target bonus levels were identified by Hewitt
Associates as being slightly  above the median level.  In awarding 2003 bonuses,
the Company reviewed the following criteria that are important to the success of
the Company's business plan:

                    o  Operating cost per BOE
                    o  Debt/Book capitalization
                    o  Reserve replacement
                    o  Finding and development cost per BOE
                    o  Production growth
                    o  General and administrative costs per BOE
                    o  Return on equity

                                       15





                    o  Net asset value per share
                    o  Growth of share value

     In determining the 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  and  operational  performance  criteria.  The
committee  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  throughout the year
and specifically evaluates Mr. Sheffield's performance relative to the Company's
performance in achieving the Company's goals.

     For 2003, the committee  awarded Mr. Sheffield and all but one of the other
executives  cash  bonuses  above  the  target  bonus  levels.  Specific  Company
performance which resulted in bonus payouts above target for 2003 included:

                    o   Base operating costs of $3.07 per BOE
                    o   Improved leverage position
                    o   Reserve replacement of 193 percent
                    o   Finding and development costs of $6.64 per BOE
                    o   Production growth of 36 percent
                    o   General and administrative cost of $1.07 per BOE
                    o   Return on equity of 26 percent
                    o   2003 stock price increase of 26 percent

     Regarding stock  performance,  the Company's  three-year  cumulative  total
return based on stock price  performance has exceeded both the Standard & Poor's
500 Index (the "S&P 500") and the DJ Secondary Oil Index per the graph below. In
addition,  the Company's  stock price hit a five-year high of $32.90 in December
2003.

     Long-Term  Incentives.  The value of the long-term incentive awards granted
to Mr.  Sheffield in 2003 was determined by a comparison of long-term  incentive
grants made to the Chief Executive  Officers of peer group companies.  The other
executive  officers were reviewed as a team.  The value of long-term  incentives
granted  to each  executive  was  determined  by  comparing  the value of awards
granted  to  peer  company  executives  holding  similar  positions,  and  their
individual  award  levels  were  averaged  to  determine  the  actual  awards to
executives of the Company.  The award levels were not  influenced by the current
stock holdings of the executives. The Company's philosophy is to award long-term
incentives  with values that are above market average.  For 2003, Mr.  Sheffield
was awarded 90,000 stock options and 12,000 shares of restricted  stock.  Hewitt
Associates  concluded the 2003 award levels  placed Mr.  Sheffield and the other
named  executives as a group between the 60th and 70th  percentile for long-term
incentive awards among the peer group.

                                       16





     A  significant   portion  of  an  executive  officer's  total  compensation
opportunity 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.

     Beginning in 2004,  to achieve this  alignment  and to emphasize  long-term
performance,  the  committee  adopted  a  performance  share  program  under the
Long-Term Incentive Plan for executives. No stock options will be awarded to Mr.
Sheffield or the named executives for 2004. This program establishes  restricted
stock award  targets for Mr.  Sheffield and each named  executive  determined by
comparing the value of awards granted to peer company executives holding similar
positions.  The target award  levels were not  influenced  by the current  stock
holdings of executives.  Restricted stock awarded under this program will have a
three-year cliff vesting requirement.

     The number of  restricted  shares  awarded each year as a percent of target
award levels will be determined by a three-step  process.  First,  the committee
will conduct a subjective evaluation of the internal Company performance against
the following one- and three-year metrics:


    One-year metrics                              Three-year metrics
    ----------------                              ------------------
                                            
    Production growth                             Reserve replacement
    Operating cost per BOE                        Finding and development cost per BOE
    General and administrative costs per BOE      Net asset value per share
    Debt statistics


     Next,  to finalize the award level for the executive  group,  the committee
will consider the Company's  Total  Shareholder  Return results  compared to the
Total  Shareholder  Return of the Company's  peer group.  As its final step, the
committee will conduct an evaluation of each executive's individual performance.

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

                             AUDIT COMMITTEE REPORT

     The Audit  Committee's  purpose is to assist the Board of  Directors in its
oversight of the Company's internal controls, financial statements and the audit
process. The Board of Directors,  in its business judgment,  has determined that
all members of the  committee  are  independent  as  required  under the listing
standards  of the New York  Stock  Exchange  ("NYSE").  The  committee  operates
pursuant to a charter  adopted by the Board of Directors.  A copy of the current
charter is posted on the Company's website at www.pioneernrc.com.

     Management is responsible for the  preparation,  presentation and integrity
of the  Company's  financial  statements,  accounting  and  financial  reporting
principles,  and internal controls and procedures  designed to assure compliance
with accounting  standards and applicable laws and regulations.  The independent
auditors, Ernst & Young LLP, are responsible for performing an independent audit
of the consolidated  financial  statements in accordance with generally accepted
auditing standards.

     In performing its oversight  role, the committee has reviewed and discussed
the audited financial  statements with management and the independent  auditors.
The  committee  has also  discussed  with the  independent  auditors the matters
required  to  be  discussed  by   Statement  on  Auditing   Standards   No.  61,
Communication  with Audit Committees,  as currently in effect. The committee has
received the written  disclosures and the letter from the  independent  auditors
required by Independence  Standards Board Standard No. 1, Independent with Audit
Committees,  as currently in effect.  The committee has also considered  whether
the  performance  of other  non-audit  services by the  independent  auditors is
compatible with  maintaining the auditors'  independence  and has discussed with
the auditors the auditors' independence.

     Based on the reports and discussions  described in this Report, and subject
to the limitations on the roles and  responsibilities  of the committee referred
to below and in the charter, the committee recommended to the Board of Directors
that the audited  financial  statements be included in the Annual Report on Form
10-K  for the year  ended  December  31,  2003,  for  filing  with the SEC.  The
committee  has also  recommended  the  selection  of the  Company's  independent
auditors.

     The members of the committee are not professionally engaged in the practice
of  auditing  or  accounting  for the  Company  and are not  experts  in auditor
independence  standards.  Members  of the  committee  rely  without  independent
verification on the information provided to them and on the representations made
by  management  and  the  independent  auditors.  Accordingly,  the  committee's
oversight does not provide an independent basis to determine that management has
maintained   appropriate   accounting  and  financial  reporting  principles  or
appropriate  internal controls and procedures designed to assure compliance with
accounting  standards and  applicable  laws and  regulations.  Furthermore,  the
committee's  considerations and discussions referred to above do not assure that
the  audit  of the  Company's  financial  statements  has  been  carried  out in
accordance  with  generally  accepted  auditing  standards,  that the  financial
statements  are  presented in  accordance  with  generally  accepted  accounting
principles or that Ernst & Young LLP is in fact independent.

                              CORPORATE GOVERNANCE

Corporate Governance Principles

     The  Board of  Directors  believes  that  sound  governance  practices  and
policies  provide an important  framework to assist it in fulfilling its duty to
shareholders.  In March  2003,  the  Board of  Directors  formally  adopted  the
Company's Corporate Governance  Principles,  which cover the following principal
subjects:
             o   Role and functions of the Board of Directors
             o   Qualifications and independence of directors
             o   Size of the Board of Directors and selection process
             o   Committee functions and independence of committee members
             o   Meetings of non-employee directors
             o   Self-evaluation
             o   Ethics and conflicts of interest (a copy of the current Code of
                 Business Conduct and Ethics  is posted on the Company's website
                 at www.pioneernrc.com)
             o   Reporting of  concerns to  non-employee directors  or the Audit
                 Committee
             o   Compensation  of the  Board  of Directors  and stock  ownership
                 requirements
             o   Succession  planning and  annual  compensation review of senior
                 management
             o   Access to senior management and to independent advisors
             o   Director orientation and continuing education
             o   Evaluation of corporate governance principles

     The Corporate Governance  Principles are posted on the Company's website at
www.pioneernrc.com.   The  Corporate  Governance  Principles  will  be  reviewed
periodically  and  as  necessary  by  the  Company's  Nominating  and  Corporate
Governance  Committee,  and  any  proposed  additions  to or  amendments  of the
Corporate Governance  Principles will be presented to the Board of Directors for
its approval.

     The  NYSE  has  adopted  rules  that  require  listed  companies  to  adopt
governance  guidelines  covering certain matters.  The Company believes that the
Corporate Governance Principles comply with the NYSE rules.

Director Independence

     The Company's  existing  standards for  determining  director  independence
require  the  assessment  of  directors'  independence  on an annual  basis.  In
February 2004, the Board of Directors  again assessed the  independence  of each
director in accordance with the  independence  standards for directors set forth
in the Company's  Corporate  Governance  Principles,  which generally  define an
independent  director as one who does not have any relationship  with management
or the Company that may  interfere  with the exercise of his or her  independent
judgment. The Board of Directors has determined, after careful review, that each
member of the Board of  Directors  is  independent,  with the  exception  of Mr.
Sheffield, who is an employee of the Company. Accordingly, eight out of the nine
current members of the Board of Directors are independent directors.

     The NYSE has adopted  rules that define  director  independence  for listed
companies. The Board of Directors has adopted Corporate Governance Principles to
ensure that the  Company's  standards for director  independence  meet or exceed
those in the NYSE rules, and evaluates director  independence in accordance with
those standards.  Based on the NYSE rules, the Board of Directors  believes that
all non-employee directors are independent.

Election of Lead Director

     In  February  2004,  the  Board  of  Directors   reelected  Mr.  Ramsey,  a
non-employee  director,  to serve as chairman of the regular private meetings of
the  independent  directors  and as Chairman  of the  Company's  Nominating  and
Corporate Governance  Committee (the "Lead Director").  Utilizing input from all
directors,  the Lead  Director  will (i) work with the CEO and  Chairman  of the
Board to determine the appropriate  agenda and information  package for Board of
Director meetings;  (ii) meet with the  CEO and  Chairman of the  Board,  senior

                                       19





management  and  individual  directors,  as required,  to  facilitate  effective
communications  and  information  flow;  (iii)  take a  leadership  role  in CEO
succession and senior  management  development;  (iv) take a leadership  role in
director evaluation,  continuing  education,  recruiting and orientation and (v)
serve as the Board of Directors  contact in the process for direct  employee and
stockholder communications with the Board of Directors.

Financial Literacy of Audit Committee and Designation of Financial Experts

     In March 2003,  the Board of Directors  evaluated  the members of the Audit
Committee for financial  literacy and the attributes of a financial expert.  The
Board of  Directors  determined  that each of the  Audit  Committee  members  is
financially  literate and that three of the Audit Committee members (Mrs. Lawson
and Messrs. Gardner and Houghton) are financial experts as defined by the SEC.

Procedure for Directly Contacting the Board of Directors and Whistleblower
Policy

     A means for  stockholders  and  employees to contact the Board of Directors
directly  has been  established  and is published  on the  Company's  website at
www.pioneernrc.com.   Matters  for  which  this  contact  may  be  used  include
allegations about actions of the Company or its directors, officers or employees
involving (i) questionable  accounting,  internal controls and auditing matters;
(ii)  materially  misleading  statements  or  omissions  in SEC  reports,  press
releases,  or other public statements or other forms of wire, mail or securities
fraud or (iii) dishonest or unethical conduct, conflicts of interest, violations
of the  Company's  code of ethics or business  conduct,  or  violation  of laws.
Information  may be  submitted  confidentially  and  anonymously,  although  the
Company may be obligated by law to disclose the  information  or identity of the
person  providing the information in connection with government or private legal
actions  and  in  some  other  circumstances.  The  Company's  policy  is not to
retaliate  against any  director,  officer or  employee  who  provides  truthful
information relating to a violation of law or Company policies.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     The  executive  officers and  directors of the Company are required to file
reports  with the SEC,  disclosing  the amount  and  nature of their  beneficial
ownership in common stock, as well as changes in that ownership.

     Based solely on its review of reports and written  representations that the
Company  has  received,  the  Company  is aware  that  Thomas C.  Halbouty,  the
Company's Vice President and Chief  Information  Officer,  and Guimar Vaca Coca,
the President of the Company's Argentine  subsidiaries,  did not timely file one
report each on Form 4 covering  transactions  effected  during 2003. The Company
believes that all other required reports were timely filed during 2003.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     During  2003,  the  Company  did  not  enter  into  any  transactions  with
management  and others,  nor was it a party to business  relationships  or other
arrangements or transactions,  that would be reportable as certain relationships
and  related  transactions.  Mr.  Jones is of counsel to the firm of  Thompson &
Knight,  L.L.P.  since his retirement from the firm in January 1998.  Thompson &
Knight,  L.L.P.  provides  periodic  legal  services to the Company.  Thompson &
Knight,  L.L.P.  customarily gives the "of counsel" title to retired partners of
the firm. Mr. Jones has no role in, and receives no pay from, Thompson & Knight,
L.L.P. except payments under a retirement savings plan.  Accordingly,  the Board
of Directors  does not consider this  relationship  to be relevant to Mr. Jones'
independence.

                              STOCKHOLDER PROPOSALS

     Any  stockholder of the Company who desires to submit a proposal for action
at the 2005 annual meeting of  stockholders  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  9, 2004,  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.

                                       23






     Any  stockholder of the Company who desires to submit a proposal for action
at the 2005  annual  meeting  of  stockholders,  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 so that it is received no later than  February 21,
2005,  unless the Company  notifies the  stockholders  otherwise.  If a Non-Rule
14a-8  Proposal is not  received by the Company on or before  February 21, 2005,
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.

     It  is  the  responsibility  of  the  Company's  Nominating  and  Corporate
Governance  Committee  to  identify,  evaluate  and  recommend  to the Board the
Directors  nominees for election at the annual meeting of stockholders,  as well
as for filling  vacancies or additions on the Board of Directors  that may occur
between  annual  meetings.  The Nominating  and Corporate  Governance  Committee
endeavors to recommend only director candidates who possess the highest personal
values and integrity; who have experience and have exhibited achievements in one
or more of the key professional, business, financial, legal and other challenges
that face a large global U.S. independent oil and gas company; who exhibit sound
judgment, intelligence,  personal character, and the ability to make independent
analytical  inquiries;  who demonstrate a willingness to devote adequate time to
Board of Director duties; and who are likely to be able to serve on the Board of
Directors for a sustained period.  Consideration will also be given to the Board
of Directors'  overall  balance of diversity of  perspectives,  backgrounds  and
experiences.

     The Nominating and Corporate Governance Committee will consider any nominee
recommended by  stockholders  for election at the annual meeting of stockholders
to be held in 2005 if that  nomination  is submitted in writing,  not later than
December 9, 2004, to the Corporate Secretary, Pioneer Natural Resources Company,
5205 North O'Connor Boulevard,  Suite 900, Irving,  Texas 75039. With respect to
each such  nominee,  the following  information  must be provided to the Company
with the written nomination:

     a)   the nominee's name, address and other personal information;

     b)   the number of shares of each class  and series of stock of the Company
          held by such nominee;

     c)   the nominating stockholder's name,  residential address and  telephone
          number, business address and telephone number; and

     d)   all other information required to be disclosed  pursuant to Regulation
          14A of the Securities and Exchange Act of 1934.

     Each submission must also 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 Nominating and Corporate Governance Committee and
the Board of Directors.

     Stockholders   desiring  to  propose   action  at  the  annual  meeting  of
stockholders  must also comply  with  Article  Nine of the Amended and  Restated
Certificate of Incorporation  of the Company.  Under Article Nine, a stockholder
must submit to the Company,  no later than 60 days before the annual  meeting or
ten days  after  the  first  public  notice  of the  annual  meeting  is sent to
stockholders, a written notice setting forth (i) the nature of the proposal with
particularity,   including   the  written  text  of  the   proposal,   (ii)  the
stockholder's name, address and other personal  information,  (iii) any interest
of the  stockholder  in the  proposed  business,  (iv) the  name of any  persons
nominated to be elected or reelected  as a director by the  stockholder  and (v)
with  respect  to each such  nominee,  the  nominee's  name,  address  and other
personal information,  the number of shares of each class and series of stock of
the Company  held by such  nominee,  all  information  required to be  disclosed
pursuant to Regulation  14A of the  Securities  and Exchange Act of 1934,  and a
notarized letter containing such nominee's acceptance of the nomination, stating
his or her  intention to serve as a director,  if elected,  and consenting to be

                                       24





named as a nominee in any proxy statement relating to such election.  The person
presiding at the annual  meeting  will  determine  whether  business is properly
brought before the meeting and will not permit the consideration of any business
not properly brought before the meeting.

     Written  requests  for  inclusion  of any  stockholder  proposal  should be
addressed to Corporate Secretary,  Pioneer Natural Resources Company, 5205 North
O'Connor  Boulevard,  Suite 900, Irving,  Texas 75039. The Company suggests that
any such proposal be sent by certified mail, return receipt requested.

                             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.

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 ten days before the Annual Meeting.
