                                 PROXY STATEMENT

                       2006 ANNUAL MEETING OF STOCKHOLDERS

     The Board of  Directors of the Company  requests  your Proxy for the Annual
Meeting of Stockholders  that will be held Wednesday,  May 3, 2006, at 9:00 a.m.
Central Time, in the Hudson Room at the Dallas  Marriott Las Colinas Hotel,  223
West Las  Colinas  Blvd.,  Irving,  Texas  75039.  By  granting  the Proxy,  you
authorize  the persons  named on the Proxy to represent you and vote your shares
at the Annual Meeting. Those 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.

     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 or by phone after the grant of the Proxy.  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.

                           DELIVERY OF PROXY MATERIALS

Mailing Date

     The approximate date on which this Proxy Statement and accompanying  Notice
of Annual  Meeting of  Stockholders  and Proxy are first  being sent or given to
stockholders is April 3, 2006.

Stockholders Sharing an Address

     Registered  Stockholders.  Registered  stockholders  (the  stockholder owns
shares in his or her own name on the books of the Company's transfer agent) will
receive one Proxy  Statement and one 2006 Annual Report for each account even if
at the same address.

     Street name  Stockholders.  Most banks and brokers are delivering  only one
copy of the Proxy  Statement and 2006 Annual  Report to  consenting  street name
stockholders (the stockholder owns shares in the name of a bank, broker or other
holder of record on the books of the  Company's  transfer  agent)  who share the
same address.  This procedure  reduces the Company's  printing and  distribution
costs.  Those who wish to receive  separate copies may do so by contacting their
bank or broker.  Similarly,  most street  name  stockholders  who are  receiving
multiple  copies  of the  Proxy  Statement  and 2006  Annual  Report at a single
address may request  that only a single set of  materials be sent to them in the
future by contacting their bank or broker. In the alternative,  most street name
stockholders  may give  instructions  to receive  separate copies or discontinue
multiple  mailings of materials by contacting  the third party that mails annual
meeting  materials  for most  banks  and  brokers  by  writing  to  Householding
Department,  ADP, 51 Mercedes Way,  Edgewood,  NY 11717,  or  telephoning  (800)
542-1061. The instructions must include the name of the stockholder's  brokerage
firm and account number.






Electronic Delivery Option

     Instead  of  receiving  future  copies  of the  proxy  materials  by  mail,
registered stockholders may elect to view future proxy materials on the internet
by following the instructions  provided when voting by internet or phone. Street
name  stockholders  may also have the  opportunity  to view  copies of the proxy
materials  electronically.  Those  who opt to do so may  contact  their  bank or
broker  regarding  the  availability  of this  service.  Opting  to  view  proxy
materials  online  will  save the  Company  the cost of  producing  and  mailing
documents to stockholders and provides immediate access to the information.  The
Notice of Annual  Meeting  of  Stockholders,  Proxy  Statement  and other  proxy
materials are also available on the Company's  website at  www.pxd.com.  Neither
the Company  website nor any other website  included in this Proxy  Statement is
intended to function  as a  hyperlink,  and the  information  contained  on such
websites is not a part of this Proxy Statement.

                                QUORUM AND VOTING

     Voting Stock.  The Company's common stock, par value $.01 per share, is the
only class of securities that entitles  holders to vote generally at meetings of
the Company's stockholders. 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 was the close of business on March 23,  2006.  As of
the  record  date,  129,264,022  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. Adoption of the Company's proposed 2006 Long-Term Incentive Plan
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 and adoption
of the Company's 2006 Long-Term Incentive Plan,  abstentions will be included in
the  number of shares  voting  and will have the  effect of a vote  against  the
proposals,  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 as Class III directors.

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


                                       2





     o   FOR the adoption of the Company's 2006 Long-Term Incentive Plan.

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.

       PARTICIPANTS IN THE PIONEER NATURAL RESOURCES USA, INC. 401(k) PLAN

     Participants  in the Pioneer  Natural  Resources USA, Inc.  401(k) Plan who
have shares of common stock credited to their plan account as of the record date
will have the right to direct  the 401(k)  Plan  trustee  regarding  how to vote
those shares.  The trustee will vote the shares in a  participant's  401(k) Plan
account in accordance with the participant's instructions or, if no instructions
are received prior to April 28, 2006, the shares credited to that  participant's
account will be voted by the trustee in the same  proportion  as it votes shares
for which it did receive timely instructions. Information as to how participants
voted the shares  credited to their 401(k) Plan account will not be disclosed to
the Company.

     If a  participant  holds  common  stock  outside  of the 401(k)  Plan,  the
participant  will also receive a Proxy  relating to those shares,  which must be
voted separately.

                                    ITEM ONE

                              ELECTION OF DIRECTORS

     The Board of Directors has nominated the following individuals for election
as Class III  Directors  of the Company  with their terms to expire in 2009 when
their successors are elected and qualified:

                               Andrew D. Lundquist
                             Charles E. Ramsey, Jr.
                                Robert A. Solberg

     Messrs. Lundquist, Ramsey and Solberg 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.

                        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" above,
the Board of Directors and executive officers of the Company will be:



Name                     Age   Position

Frank A. Risch ........   63   Director
Mark S. Sexton ........   50   Director
Robert A. Solberg......   60   Director
Jim A. Watson  ........   67   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
either they are  reelected or their  successors  are elected and  qualified.  In
addition, the Company's bylaws terminate the term of a director immediately upon
the director  reaching 75 years of age, as Dr.  Baroffio  will on March 21, 2007
prior to the end of his current term in 2008. Mr. James L. Houghton's service as
director of the Company  terminated  in December  2005 upon reaching 75 years of
age.  Mr. Jerry P. Jones'  service as director of the Company will  terminate at
the Annual Meeting because the retirement  provisions of the Company's bylaws do
not permit him to stand for  reelection.  Each year,  the directors of one class
stand for reelection as their terms of office expire. Messrs. Gardner, Risch and
Sexton and Mrs.  Lawson are  designated  as Class I Directors and their terms of
office  expire in 2007.  Messrs.  Baroffio,  Buchanan,  Sheffield and Watson are
designated  as Class II  Directors  and their  terms of  office  expire in 2008.
Messrs. Lundquist,  Ramsey and Solberg are designated as Class III Directors and
their terms of office expire at the Annual Meeting.

     Executive officers serve at the discretion of the Board of Directors.

     Set forth below is  biographical  information  about each of the  Company's
executive officers and directors named above.

                                    ITEM TWO

                RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     The Audit  Committee of the Board of Directors  has selected  Ernst & Young
LLP as the independent  auditors of the Company for 2006. Ernst & Young LLP have
audited the Company's  financial  statements  since 1998.  The 2005 audit of the
Company's annual consolidated financial statements and effectiveness of internal
control over financial reporting was completed on February 15, 2006.

     The Board of Directors is submitting the selection of Ernst & Young LLP for
ratification at the Annual  Meeting.  The submission of this matter for approval
by  stockholders  is not legally  required,  but the Board of Directors  and the
Audit Committee believe the submission  provides an opportunity for stockholders
to  communicate  through  their vote with the Board of  Directors  and the Audit
Committee about an important aspect of corporate governance. If the stockholders
do not  ratify the  selection  of Ernst & Young LLP,  the Audit  Committee  will
reconsider the selection of that firm as the Company's auditors.

     The Audit  Committee has the sole authority and  responsibility  to retain,
evaluate and replace the Company's auditors.  The stockholders'  ratification of
the  appointment  of Ernst & Young LLP does not limit the authority of the Audit
Committee to change auditors at any time.

     Audit  Fees.  The  aggregate  fees of  Ernst & Young  LLP for  professional
services rendered for the audits of the Company's annual consolidated  financial
statements  included in its Annual  Report on Form 10-K,  audit of the Company's
internal control over financial  reporting,  reviews of the Company's  quarterly
financial  statements included in its Quarterly Reports on Form 10-Q and reviews
of the Company's other filings with the Securities and Exchange  Commission (the
"SEC") including comfort letters,  consents and other research work necessary to
comply with generally  accepted auditing  standards for the years ended December
31, 2005 and 2004 were $1,187,000 and $987,000, respectively.

     Audit-Related   Fees.   The  aggregate  fees  of  Ernst  &  Young  LLP  for
audit-related  services  provided  to the  Company  totaled  $46,000 and $42,000
during  each of the  years  ended  December  31,  2005 and  2004.  Audit-related
services  were  comprised  of audits of the  Company's  401(k)  plan and certain
affiliated partnerships.

     Tax Services Fees. The aggregate fees of Ernst & Young LLP for tax services
provided to the  Company  totaled  $49,000  and  $82,000  during the years ended
December 31, 2005 and 2004, respectively.  Tax services were primarily comprised
of  tax  return   preparation   services  for   expatriates  and  the  Company's
international subsidiaries.

     Other  Fees.  The  aggregate  fees of Ernst & Young LLP for other  services
provided  to the  Company  during the years  ended  December  31,  2005 and 2004
totaled  $6,500 for each year.  The other  services were  comprised of access to
Ernst & Young LLP's on-line research services.

     The  Charter  of the  Company's  Audit  Committee  requires  that the Audit
Committee  review  and  pre-approve  the plan and  scope of Ernst & Young  LLP's
audit,  audit-related,  tax and other services. During 2005, the Audit Committee
pre-approved  100 percent of the  services  described  above under the  captions
"Audit-Related Fees," "Tax Services Fees" and "Other Fees."

     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  consolidated
financial  statements for 2005, 2004 and 2003 did not contain an adverse opinion
or a disclaimer of opinion and was not  qualified or modified as to  uncertainty
or audit scope. The audit report of Ernst & Young LLP on management's assessment
that the Company maintained  effective internal control over financial reporting
as of  December  31,  2005 and 2004 did not  contain  an  adverse  opinion  or a
disclaimer  of opinion and was not  qualified or modified as to  uncertainty  or
audit scope.


                                       9






     In  connection  with  the  audits  of  the  Company's  annual  consolidated
financial  statements for 2005, 2004 and 2003, 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.

                                   ITEM THREE

                  ADOPTION OF THE 2006 LONG-TERM INCENTIVE PLAN

General

     The Compensation and Management  Development Committee (the "Committee") of
the Board of Directors has  recommended,  subject to stockholder  approval,  the
adoption of the Company's  2006 Long-Term  Incentive  Plan (the "2006 Plan").  A
summary  description  of the  material  features  of the 2006  Plan is set forth
below.  The 2006 Plan document has been filed with the  Securities  and Exchange
Commission  as  Appendix  A to  this  Proxy  Statement  and is  incorporated  by
reference into this proposal.

     The Company  currently  sponsors  the  Pioneer  Natural  Resources  Company
Long-Term Incentive Plan, which was adopted in 1997 (the "1997 LTIP"),  pursuant
to which 5,064,330 shares of common stock were the subject of outstanding awards
as of March 14, 2006. In addition,  8,127,613  shares  remain  available for new
awards  under the 1997 LTIP (as  compared to the  4,600,000  shares that will be
authorized  for issuance under the 2006 Plan) as of March 14, 2006. The exercise
prices for  outstanding  stock  options  under the 1997 LTIP range from $5.81 to
$42.44 per share. Currently, the 1997 LTIP provides for the granting of options,
performance  units,  restricted  stock awards,  restricted stock units and stock
appreciation rights. If the 2006 Plan is approved,  no additional awards will be
made under the 1997 LTIP.

     With the approval of the 2006 Plan, the Company will be able to continue to
use an array of equity  compensation  alternatives  in structuring  compensation
arrangements for Company  personnel,  directors and  consultants.  The 2006 Plan
will make  available  awards  through  which  eligible  persons  may acquire and
maintain  stock  ownership  in the  Company.  While  the Board of  Directors  is
cognizant of the potential  dilutive effect of compensatory stock awards and the
expense reflected on the Company's  statement of operations,  it also recognizes
the significant  motivational  and  performance  benefits that are achieved from
making such awards.  No award may be granted under the 2006 Plan on or after the
ten year anniversary of its effectiveness.

Description of the Proposed Plan

     The  description  of the 2006  Plan set  forth  below is a  summary  of the
material features of the 2006 Plan as proposed. This summary does not purport to
be a complete description of all the provisions of the 2006 Plan. The purpose of
the 2006 Plan is to  provide a means to  enhance  the  profitable  growth of the
Company and its  subsidiaries by attracting and retaining  employees,  directors
and  consultants of the Company  through  affording such  individuals a means to
acquire and maintain  stock  ownership or awards,  the value of which is tied to
the  performance  of the common stock.  The 2006 Plan also  provides  additional
incentives and reward  opportunities  designed to strengthen  such  individuals'
concern for the welfare of the Company and their desire to remain in its employ.
The 2006 Plan achieves this purpose by permitting  grants of (i) incentive stock
options  ("Incentive  Options"),  (ii) options that do not constitute  incentive
stock options  ("Nonstatutory  Options," and together  with  Incentive  Options,
"Options"),  (iii) restricted  stock awards  ("Restricted  Stock Awards"),  (iv)
restricted stock units ("Restricted Stock Units"), (v) stock appreciation rights
("SARs"),  or (vi) any combination of such awards  (collectively  referred to as
"Awards"). See "- Securities To Be Offered."



                                       10





     The 2006 Plan,  in part,  is intended to qualify  under the  provisions  of
section 422 of the Internal  Revenue Code of 1986, as amended (the "Code").  The
2006 Plan is not subject to the  provisions  of the Employee  Retirement  Income
Security Act of 1974, as amended ("ERISA").

Administration of the 2006 Long-Term Incentive Plan

     The Board of  Directors  of the  Company has  appointed  the  Committee  to
administer  the 2006  Plan  pursuant  to its  terms  and all  applicable  state,
federal,  or other  rules or laws,  except in the  event the Board of  Directors
chooses to take action under the 2006 Plan. Unless otherwise limited by the 2006
Plan, Rule 16b-3 of the Securities Exchange Act of 1934 (the "Exchange Act"), or
any provisions of the Code, the Committee has broad discretion to administer the
2006 Plan,  interpret its provisions,  and adopt policies for  implementing  the
2006 Plan.  This  discretion  includes the power to  determine  when and to whom
Awards will be granted,  determine the amount of such Awards  (measured in cash,
shares of common stock or as otherwise designated),  prescribe and interpret the
terms and  provisions  of each  Award  agreement  (the terms of which may vary),
delegate duties under the 2006 Plan,  terminate,  modify or amend the 2006 Plan,
and  execute all other  responsibilities  permitted  or required  under the 2006
Plan.

Persons Who May Participate in the 2006 Long-Term Incentive Plan

     Any  individual who provides  services to the Company or its  subsidiaries,
including  non-employee  directors  of  and  consultants  for  the  Company  (an
"Eligible  Person"),  and who is designated by the Committee to receive an Award
under the 2006 Plan will be a "Participant." An employee on leave of absence may
be  considered  still  employed by the Company or a  subsidiary  for purposes of
determining  eligibility for  participation  under the 2006 Plan. Any individual
granted an Award which  remains  outstanding  under the 2006 Plan,  including an
individual  who  is  no  longer  an  Eligible  Person,  will  continue  to  be a
Participant  for  purposes  of the  2006  Plan.  The  Company  currently  has 11
non-employee  directors, 18 officers and approximately 1,500 other employees who
are eligible to participate in the 2006 Plan.

     With respect to a grant of Incentive Options, which comply with Section 422
of the Code,  a  Participant  must be an  employee  of the Company or one of its
corporate  subsidiaries and, immediately before the time the Incentive Option is
granted, the Participant may not own stock possessing more than 10% of the total
combined  voting  power or value of all  classes  of stock of the  Company  or a
subsidiary  unless,  at the time the Incentive  Option is granted,  the exercise
price of the  Incentive  Option is at least 110% of the fair market value of the
common stock underlying the Incentive Option.

Maximum Number of Shares Subject to Award

     A  Participant  under the 2006 Plan will be  eligible  to  receive an Award
pursuant to the terms of the 2006 Plan and subject to any limitations imposed by
appropriate  action  of the  Committee.  No Award  may be  granted  if the Award
relates to a number of shares of common stock which exceeds the number of shares
which remain  available  under the 2006 Plan minus the number of shares issuable
in  settlement  of or  relating  to  outstanding  Awards  under  the 2006  Plan.
Additionally,  in each fiscal year or 12-month period, as applicable, during any
part of which the 2006 Plan is in effect,  a "Covered  Employee" for purposes of
section  162(m) of the Code  (discussed  below)  may not be  granted  (i) Awards
(other than  Awards  designated  to be paid only in cash)  relating to more than
250,000  shares of common stock,  subject to  adjustment in a manner  consistent
with the other  provisions  of the 2006 Plan,  and (ii) Awards  designated to be
paid only in cash  having a value  determined  on the date of grant in excess of
$4,000,000.

Securities to be Offered

     Shares Subject to the 2006 Plan. The maximum  aggregate number of shares of
common  stock  that may be granted  for any and all  Awards  under the 2006 Plan
shall  not  exceed   4,600,000   shares   (subject  to  any  adjustment  due  to
recapitalization or reorganization permitted under the 2006 Plan), and the total
number  of shares of  common  stock  received  and  available  for  delivery  in
connection with Incentive  Options under the 2006 Plan will not exceed 4,600,000
shares.  If common stock subject to any Award is not issued or  transferred,  or
ceases  to be  issuable  or  transferable  for any  reason,  including  (but not
exclusively) because an Award is forfeited,  terminated, expires unexercised, is
settled in cash in lieu of common  stock or is  otherwise  terminated  without a
delivery  of shares to a  Participant,  the  shares  of common  stock  that were
subject to that Award will again be  available  for issue,  transfer or exercise
pursuant  to Awards  under the 2006 Plan to the  extent  allowable  by law.  The


                                       11






common stock subject to Awards  pursuant to the 2006 Plan may be authorized  but
unissued  shares,  shares held by the Company in  treasury,  or shares that have
been  reacquired by the Company,  including  shares that have been bought on the
market for the  purposes of the 2006 Plan.  The fair market  value of the common
stock on a given date will be the  closing  price of a share of common  stock so
reported  by the New York Stock  Exchange  ("NYSE")  on the most  recent date on
which  shares of  common  stock  were  publicly-traded  preceding  the date with
respect to which the fair market value determination is made. There are no fees,
commissions or other charges  applicable to a purchase of common stock under the
2006 Plan.

Awards

     Stock Options. The Company may grant Options to Eligible Persons, including
(i) Incentive  Options  (only to employees of the Company or its  subsidiaries),
which comply with  section 422 of the Code and (ii)  Nonstatutory  Options.  The
exercise  price of each Option granted under the 2006 Plan will be stated in the
Option agreement and may vary; provided, however, that the exercise price for an
Option  must not be less  than the  greater  of (a) the par  value  per share of
common  stock or (b) 100% of the fair market value per share of the common stock
as of the date of grant of the Option. Options may be exercised as the Committee
determines,  but not  later  than ten years  from the date of  grant.  Incentive
Options  will not be granted  more than ten years after the approval of the 2006
Plan by the Company's  stockholders.  Any Incentive  Option that fails to comply
with section 422 of the Code for any reason will result in the  reclassification
of the Option as a Nonstatutory  Option,  which will be exercisable as such. The
Committee  will determine the methods and form of payment for the exercise price
of an Option (including,  in the discretion of the Committee,  payment in common
stock,  other  Awards,  or other  property)  and the  methods and forms in which
common stock  (including  common stock issuable  pursuant to the Option) will be
delivered to a Participant.

     SARs.  An SAR is the right to receive an amount  equal to the excess of the
fair market value of one share of the common stock on the date of exercise  over
the grant price of the SAR, as determined by the Committee.  SARs may be awarded
in connection  with or separate from an Option.  SARs awarded in connection with
an Option will  entitle the holder,  upon  exercise,  to  surrender  the related
Option or portion thereof  relating to the number of shares for which the SAR is
exercised.  The  surrendered  Option or  portion  thereof  will then cease to be
exercisable. However, an SAR awarded in connection with an Option is exercisable
only to the  extent  that  the  related  Option  is  exercisable.  SARs  granted
independently of an Option will be exercisable as the Committee determines.  The
term of an SAR will be for a period  determined  by the  Committee  but will not
exceed ten years.  SARs may be paid in cash,  stock or a combination of cash and
stock, as the Committee provides in the Award agreement governing the SAR.

     Restricted  Stock Awards.  A Restricted Stock Award is a grant of shares of
common stock subject to a risk of forfeiture,  restrictions on  transferability,
and  any  other  restrictions  imposed  by  the  Committee  in  its  discretion.
Restrictions may lapse at such times and under such  circumstances as determined
by the Committee.  Except as otherwise provided under the terms of the 2006 Plan
or an Award agreement, the holder of a Restricted Stock Award may have rights as
a  stockholder,  including  the right to vote the  common  stock  subject to the
Restricted  Stock Award or to receive  dividends on the common stock  subject to
the Restricted  Stock Award (and subject to any mandatory  reinvestment or other
requirements  imposed by the  Committee).  As a condition of a Restricted  Stock
Award grant, the Committee may require or permit a Participant to elect that any
cash  dividends  paid on a share of common stock  subject to a Restricted  Stock
Award be  automatically  reinvested  in  additional  Restricted  Stock Awards or
applied  to the  purchase  of  additional  Awards  under the 2006  Plan.  Unless
otherwise  determined by the Committee,  common stock  distributed in connection
with a stock  split or stock  dividend,  and  other  property  distributed  as a
dividend,  will be subject to restrictions  and a risk of forfeiture to the same
extent as the Restricted  Stock Award with respect to which such common stock or
other property has been distributed.  During the restricted period applicable to
the  Restricted  Stock,  the  Restricted  Stock  may not be  sold,  transferred,
pledged, hypothecated, margined or otherwise encumbered by the Participant.

     Restricted Stock Units. Restricted Stock Units are rights to receive common
stock,  cash, or a  combination  of both at the end of a specified  period.  The
Committee may subject Restricted Stock Units to restrictions  (which may include
a risk  of  forfeiture)  to be  specified  in the  Award  agreement,  and  those
restrictions  may lapse at such times  determined by the  Committee.  Restricted
Stock Units may be satisfied by delivery of common stock, cash equal to the fair
market value of the  specified  number of shares of common stock  covered by the
Restricted Stock Units, or any combination  thereof  determined by the Committee


                                       12





at the date of grant or thereafter. Dividend equivalents on the specified number
of shares of common stock covered by  Restricted  Stock Units will be either (i)
paid with respect to such Restricted Stock Units on the dividend payment date in
cash or in shares of unrestricted  common stock having a fair market value equal
to the amount of such  dividends,  or (ii)  automatically  deemed  reinvested in
additional  Restricted Stock Units,  other Awards, or other investment  vehicles
permitted by the  Committee  and elected by the  Participant,  unless  otherwise
determined by the Committee on the date of grant.

     Bonus Stock and Awards in Lieu of Company  Obligations.  The  Committee  is
authorized  to grant common stock as a bonus,  or to grant common stock or other
Awards in lieu of  obligations  to pay cash or deliver other  property under the
2006 Plan or under  other  plans or  compensatory  arrangements,  subject to any
applicable  provision  under Section 16 of the Exchange Act. The Committee  will
determine any terms and conditions applicable to grants of common stock or other
Awards,  including  performance  criteria associated with an Award. Any grant of
common stock to an officer of the Company or a  subsidiary  in lieu of salary or
other cash compensation will be reasonable, as determined by the Committee.

     Dividend  Equivalents.  Dividend  equivalents  may be granted,  entitling a
Participant to receive cash, common stock, other Awards, or other property equal
in value to  dividends  paid with  respect  to a  specified  number of shares of
common stock,  or other  periodic  payments at the  discretion of the Committee.
Dividend  equivalents  may be awarded on a  freestanding  basis or in connection
with another Award. The Committee may provide that dividend  equivalents will be
payable or  distributed  when accrued or that they will be deemed  reinvested in
additional  common stock,  Awards, or other investment  vehicles.  The Committee
will specify any  restrictions on  transferability  and risks of forfeiture that
are imposed upon dividend equivalents.

     Other  Stock-Based  Awards.   Participants  may  be  granted,   subject  to
applicable  legal  limitations  and the terms of the 2006 Plan and its purposes,
other  Awards  related to common stock (in terms of being  valued,  denominated,
paid or  otherwise  defined  by  reference  to common  stock).  Such  Awards may
include,  but are not limited to,  convertible or exchangeable  debt securities,
other rights convertible or exchangeable into common stock,  purchase rights for
common stock,  Awards with value and payment  contingent upon performance of the
Company or any other factors  designated by the Committee,  and Awards valued by
reference to the book value of common stock or the value of securities of or the
performance  of specified  subsidiaries.  The Committee will determine the terms
and  conditions  of all such Awards,  including  without  limitation,  method of
delivery,  consideration to be paid, the timing and methods of payment,  and any
performance  criteria  associated  with an Award.  Cash awards may granted as an
element of or a supplement to any Awards permitted under the 2006 Plan.

     Performance Awards. The Committee may designate that certain Awards granted
under the 2006 Plan constitute  "performance" Awards  ("Performance  Awards") or
may grant separate cash bonus annual incentive  awards as Performance  Awards. A
Performance  Award is any Award,  the grant,  exercise or settlement of which is
subject to one or more performance standards.  Additionally, a Performance Award
is an Award  granted to a person  designated  by the  Committee,  at the time of
grant of the Performance  Award,  as likely to be a Covered  Employee within the
meaning of section 162(m) of the Code and the regulations  thereunder (including
Treasury  Regulation  ss.  1.162-27 and successor  regulations  thereto) for the
fiscal year. One or more of the following business criteria for the Company,  on
a  consolidated  basis,  and/or  for  specified   subsidiaries  or  business  or
geographical  units of the Company (except with respect to the total shareholder
return  and  earnings  per share  criteria)  shall be used by the  Committee  in
establishing  performance  goals:  (i)  earnings  per share;  (ii)  increase  in
revenues;  (iii) increase in cash flow;  (iv) increase in cash flow return;  (v)
return on net assets;  (vi) return on assets and/or return on investment;  (vii)
return on capital;  (viii)  return on equity;  (ix)  economic  value added;  (x)
operating margin;  (xi)  contribution  margin;  (xii) net income;  (xiii) pretax
earnings;  (xiv) pretax earnings before  interest,  depreciation,  amortization,
exploration and abandonment costs; (xv) pretax operating earnings after interest
expense and before incentives, service fees, and extraordinary or special items,
or operating  income;  (xvi) total  stockholder  return;  (xvii) debt reduction;
(xviii)  production  growth;  (xix) general and  administrative  expenses;  (xx)
reserve  replacement;  (xxi)  finding and  development  costs;  (xxii) net asset
value;  (xxiii) operating costs; and (xxiv) any of the above goals determined on
an absolute or relative  basis or as compared to the  performance of a published
or special index deemed applicable by the Committee  including,  but not limited
to, the Standard & Poor's 500 Stock Index or a selected group of companies.


                                       13





Other Provisions

     Tax  Withholding.  At  the  discretion  of the  Committee  and  subject  to
conditions that the Committee may impose, a Participant's  minimum statutory tax
withholding  with respect to an Award may be satisfied by  withholding  from any
payment  related  to an Award or by the  withholding  of shares of common  stock
issuable pursuant to the Award based on the fair market value of the shares.

     Merger  or  Recapitalization.  If any  change  is  made  to  the  Company's
capitalization,  such as a  stock  split,  stock  combination,  stock  dividend,
exchange of shares or other recapitalization, merger or otherwise, which results
in an increase or decrease in the number of outstanding  shares of common stock,
appropriate adjustments will be made by the Committee as to the number and price
of shares subject to an Award under the 2006 Plan.

     Change in Control. Upon a Change in Control (as such term is defined in the
2006 Plan),  with respect only to Awards held by Participants  who are employees
or  directors  of the  Company,  (i) all  outstanding  SARs  and  Options  shall
immediately  become fully vested and  exercisable in full;  (ii) the restriction
period of any Restricted Stock Award or Restricted Stock Unit shall  immediately
be accelerated  and the  restrictions  shall expire;  and (iii) the  performance
goals  established  under any Performance  Award will be deemed to have been met
for all  performance  periods and the holder will be paid a pro rata  portion of
all associated targeted performance goals.

     Amendment.  Without  stockholder  or  Participant  approval,  the  Board of
Directors may amend, alter,  suspend,  discontinue or terminate the 2006 Plan or
the  Committee's  authority  to grant  Awards  under the plan,  except  that any
amendment or  alteration  to the 2006 Plan,  including any increase in any share
limitation,  shall be subject to the approval of the Company's  stockholders not
later than the next annual  meeting if  stockholder  approval is required by any
state or  federal  law or  regulation  or the  rules of the  NYSE.  The Board of
Directors  may  otherwise,  in its  discretion,  determine  to submit other such
changes to the 2006 Plan to stockholders  for approval.  The Committee may waive
any  conditions  or rights  under,  or amend,  alter,  suspend,  discontinue  or
terminate  any  Award  theretofore  granted  and any  Award  agreement  relating
thereto,  except as otherwise provided in the 2006 Plan; provided,  that without
the consent of an affected Participant,  no such Committee action may materially
and adversely affect the rights of such Participant under such Award.

     Transferability  of Awards.  In accordance with the rules prescribed by the
Committee, the Committee may permit a person to transfer, in the form of a gift,
Nonstatutory  Options or SARs,  or may authorize all or a portion of such Awards
to be granted to an  Eligible  Person on terms  which  permit  transfer  by such
Participant  (i)  to  a  child,  stepchild,   grandchild,   parent,  stepparent,
grandparent,  spouse,  former spouse,  sibling,  niece,  nephew,  mother-in-law,
father-in-law,  son-in-law,  daughter-in-law,  brother-in-law,  or sister-in-law
(including  adoptive  relationships),  and any person sharing the household of a
holder of such  Award  ("Immediate  Family  Members");  (ii) to a trust in which
Immediate  Family  Members  have  more  than  fifty  percent  of the  beneficial
interest;  (iii) a foundation  in which  Immediate  Family  Members  control the
management of assets; or (iv) any other entity in which Immediate Family Members
own more than fifty percent of the voting interests.  An Option, SAR, Restricted
Stock Unit or Restricted  Stock Award may be transferred  pursuant to a domestic
relations order. Other than as described above,  Awards will not be transferable
other than by will or the laws of descent and distribution.  Notwithstanding any
provision to the contrary, Incentive Options will not be transferable other than
by will or the laws of descent and distribution.

Federal Tax Consequences

     The following discussion is for general information only and is intended to
summarize briefly the U.S. federal tax consequences to Participants arising from
participation  in the 2006 Plan. This description is based on current law, which
is subject to change (possibly retroactively). The tax treatment of Participants
in the  2006  Plan may  vary  depending  on the  particular  situation  and may,
therefore,  be subject to special rules not discussed below. No attempt has been
made to discuss any potential foreign, state, or local tax consequences.

     Incentive  Options;  Nonstatutory  Options;  SARs.  Participants  will  not
realize  taxable income upon the grant of a Nonstatutory  Option or an SAR. Upon
the  exercise of a  Nonstatutory  Option or SAR, a  Participant  will  recognize
ordinary  compensation  income  (subject to  withholding  by the  Company) in an
amount  equal to the excess of (i) the amount of cash and the fair market  value
of the  common  stock  received,  over  (ii) the  exercise  price  (if any) paid


                                       14





therefor.  A Participant will generally have a tax basis in any shares of common
stock  received  pursuant  to the  exercise  of an SAR,  or pursuant to the cash
exercise of a  Nonstatutory  Option,  that equals the fair market  value of such
shares on the date of  exercise.  Subject to the  discussion  under  "--Tax Code
Limitations  on  Deductibility"  below,  the Company (or a  subsidiary)  will be
entitled to a deduction for federal  income tax purposes that  corresponds as to
timing and amount with the compensation income recognized by a Participant under
the foregoing rules.

     Participants  eligible to receive an  Incentive  Option will not  recognize
taxable  income on the grant of an  Incentive  Option.  Upon the  exercise of an
Incentive Option, a Participant will not recognize taxable income,  although the
excess of the fair  market  value of the shares of common  stock  received  upon
exercise of the  Incentive  Option ("ISO  Stock")  over the exercise  price will
increase the alternative  minimum taxable income of the  Participant,  which may
cause such  Participant  to incur  alternative  minimum  tax. The payment of any
alternative  minimum tax  attributable  to the exercise of an  Incentive  Option
would be allowed as a credit against the Participant's  regular tax liability in
a later year to the extent the Participant's  regular tax liability is in excess
of the alternative minimum tax for that year.

     Upon the  disposition  of ISO Stock  that has been  held for the  requisite
holding  period  (generally,  at least two years  from the date of grant and one
year from the date of exercise of the  Incentive  Option),  a  Participant  will
generally recognize capital gain (or loss) equal to the excess (or shortfall) of
the amount  received  in the  disposition  over the  exercise  price paid by the
Participant for the ISO Stock.  However, if a Participant  disposes of ISO Stock
that has not been  held  for the  requisite  holding  period  (a  "Disqualifying
Disposition"),  the Participant will recognize ordinary  compensation  income in
the year of the  Disqualifying  Disposition  in an amount equal to the amount by
which  the fair  market  value of the ISO Stock at the time of  exercise  of the
Incentive  Option  (or,  if less,  the amount  realized  in the case of an arm's
length disposition to an unrelated party) exceeds the exercise price paid by the
Participant for such ISO Stock. A Participant  would also recognize capital gain
to the extent the amount realized in the Disqualifying  Disposition  exceeds the
fair market value of the ISO Stock on the exercise  date. If the exercise  price
paid  for  the  ISO  Stock  exceeds  the  amount  realized  (in  the  case of an
arm's-length  disposition to an unrelated  party),  such excess would ordinarily
constitute a capital loss.

     The  Company and its  subsidiaries  will  generally  not be entitled to any
federal income tax deduction upon the grant or exercise of an Incentive  Option,
unless a Participant  makes a  Disqualifying  Disposition of the ISO Stock. If a
Participant  makes a  Disqualifying  Disposition,  the Company (or a subsidiary)
will then,  subject to the  discussion  below under "--Tax Code  Limitations  on
Deductibility," be entitled to a tax deduction that corresponds as to timing and
amount with the compensation  income recognized by a Participant under the rules
described in the preceding paragraph.

     Under current rulings, if a Participant transfers previously held shares of
common  stock  (other  than ISO Stock  that has not been held for the  requisite
holding  period)  in  satisfaction  of part or all of the  exercise  price  of a
Nonstatutory  Option or Incentive  Option, no additional gain will be recognized
on  the  transfer  of  such  previously  held  shares  in  satisfaction  of  the
Nonstatutory  Option or Incentive  Option exercise price (although a Participant
would  still  recognize  ordinary   compensation  income  upon  exercise  of  an
Nonstatutory  Option in the manner described  above).  Moreover,  that number of
shares of common stock  received upon exercise which equals the number of shares
of previously  held common stock  surrendered  therefor in  satisfaction  of the
Nonstatutory  Option or Incentive  Option  exercise  price will have a tax basis
that equals, and a capital gains holding period that includes, the tax basis and
capital  gains  holding  period of the  previously  held shares of common  stock
surrendered  in  satisfaction  of the  Nonstatutory  Option or Incentive  Option
exercise  price.  Any  additional  shares of common stock received upon exercise
will  have a tax  basis  that  equals  the  amount  of cash (if any) paid by the
Participant,   plus  the  amount  of  compensation   income  recognized  by  the
Participant under the rules described above.

     The 2006 Plan  allows the  Committee  to permit the  transfer  of Awards in
limited circumstances. See "--Other Provisions - Transferability of Awards." For
income and gift tax purposes, certain transfers of Nonstatutory Options and SARs
generally should be treated as completed gifts, subject to gift taxation.

     The Internal  Revenue  Service (the "IRS") has not provided formal guidance
on the income tax consequences of a transfer of Nonstatutory Options (other than
in the context of divorce) or SARs.  However,  the IRS has informally  indicated


                                       15





that after a transfer of stock options,  the transferor  will recognize  income,
which will be subject to withholding, and FICA/FUTA taxes will be collectible at
the time the transferee exercises the stock options.

     In addition,  if the Participant  transfers a vested Nonstatutory Option to
another  person and  retains no  interest  in or power over it, the  transfer is
treated  as  a  completed  gift.  The  amount  of  the  transferor's   gift  (or
generation-skipping   transfer,  if  the  gift  is  to  a  grandchild  or  later
generation) equals the value of the Nonstatutory Option at the time of the gift.
The  value of the  Nonstatutory  Option  may be  affected  by  several  factors,
including the difference between the exercise price and the fair market value of
the stock,  the potential for future  appreciation or depreciation of the stock,
the  time  period  of  the  Nonstatutory  Option  and  the  illiquidity  of  the
Nonstatutory Option. The transferor will be subject to a federal gift tax, which
will be limited  by (i) the annual  exclusion  of  $12,000  per donee,  (ii) the
transferor's  lifetime  unified  credit,  or (iii)  the  marital  or  charitable
deductions.  The  gifted  Nonstatutory  Option  will  not  be  included  in  the
Participant's  gross  estate  for  purposes  of the  federal  estate  tax or the
generation-skipping transfer tax.

     This favorable tax treatment for vested  Nonstatutory  Options has not been
extended to unvested  Nonstatutory  Options.  Whether such consequences apply to
unvested Nonstatutory Options is uncertain and the gift tax implications of such
a transfer is a risk the transferor  will bear upon such a disposition.  The IRS
has not specifically addressed the tax consequences of a transfer of SARs.

     Restricted Stock Awards; Restricted Stock Units; Cash Awards. A Participant
will recognize ordinary  compensation  income upon receipt of cash pursuant to a
cash award or, if earlier,  at the time the cash is otherwise made available for
the Participant to draw upon. A Participant  will not have taxable income at the
time of grant of a stock Award in the form of Restricted Stock Units denominated
in common stock,  but rather,  will generally  recognize  ordinary  compensation
income at the time he receives  common stock in  satisfaction  of the Restricted
Stock  Units in an amount  equal to the fair  market  value of the common  stock
received.  In general, a Participant will recognize ordinary compensation income
as a result of the receipt of common stock pursuant to a Restricted  Stock Award
or Bonus Stock Award in an amount  equal to the fair market  value of the common
stock when such stock is received;  provided,  however, that if the stock is not
transferable and is subject to a substantial risk of forfeiture when received, a
Participant will recognize  ordinary  compensation  income in an amount equal to
the fair  market  value of the  common  stock (i) when the  common  stock  first
becomes  transferable  or  is  no  longer  subject  to  a  substantial  risk  of
forfeiture,  in cases where a Participant  does not make an valid election under
Section  83(b) of the Code or (ii) when the common stock is  received,  in cases
where a Participant makes a valid election under Section 83(b) of the Code.

     A Participant will be subject to withholding for federal, and generally for
state and local,  income taxes at the time he recognizes  income under the rules
described  above with respect to common stock or cash  received.  Dividends that
are received by a  Participant  prior to the time that the common stock is taxed
to the  Participant  under the rules  described in the  preceding  paragraph are
taxed as additional  compensation,  not as dividend income. The tax basis in the
common stock received by a Participant  will equal the amount  recognized by him
as compensation income under the rules described in the preceding paragraph, and
the Participant's  capital gains holding period in those shares will commence on
the later of the date the shares are received or the restrictions lapse.

     Subject to the discussion  immediately below, the Company (or a subsidiary)
will be entitled to a deduction for federal income tax purposes that corresponds
as to timing and amount with the compensation income recognized by a Participant
under the foregoing rules.

     Tax Code Limitations on  Deductibility.  In order for the amounts described
above to be  deductible  by the Company (or a  subsidiary),  such  amounts  must
constitute  reasonable  compensation for services rendered or to be rendered and
must be ordinary and necessary business expenses.

     The  ability of the  Company (or a  subsidiary)  to obtain a deduction  for
future  payments  under  the 2006  Plan  could  also be  limited  by the  golden
parachute  payment  rules  of  Section  280G  of the  Code,  which  prevent  the
deductibility  of certain excess  parachute  payments made in connection  with a
change in control of an employer-corporation.

     Finally, the ability of the Company (or a subsidiary) to obtain a deduction
for amounts  paid under the 2006 Plan could be limited by Section  162(m) of the
Code,  which  limits the  deductibility,  for federal  income tax  purposes,  of
compensation paid to certain executive officers of a publicly traded corporation
to  $1,000,000  with respect to any such officer  during any taxable year of the

                                       16





corporation.  However,  an exception  applies to this  limitation in the case of
certain  performance-based  compensation.  In order to exempt  performance-based
compensation from the $1,000,000 deductibility limitation,  the grant or vesting
of the Award relating to the  compensation  must be based on the satisfaction of
one or more  performance  goals as selected by the Committee.  Performance-based
Awards  intended to comply with Section 162(m) of the Code may not be granted in
a given  period if such Awards  relate to shares of common  stock which exceed a
specified limitation or,  alternatively,  the  performance-based  Awards may not
result in  compensation,  for a  Participant,  in a given period which exceeds a
specified  limitation.  If the 2006 Plan is  approved at the Annual  Meeting,  a
Participant   who   receives  an  Award  or  Awards   intended  to  satisfy  the
performance-based  exception to the $1,000,000  deductibility limitation may not
receive  performance-based Awards relating to more than 250,000 shares of common
stock  or,  with  respect  to Awards  not  related  to  shares of common  stock,
$4,000,000, in any given fiscal year. Although the 2006 Plan has been drafted to
satisfy the requirements for the performance-based  compensation exception,  the
Company  may  determine  that it is in its best  interests  not to  satisfy  the
requirements for the exception. See "Awards - Performance Awards."

Long-Term Incentive Plan Benefit Table

     As of the date of this Proxy Statement,  no director,  executive officer or
employee  of the Company has been  granted any Awards  under the 2006 Plan.  The
Awards, if any, that will be granted to eligible persons under the 2006 Plan are
subject to the discretion of the Committee and, therefore, are not determinable.
The following  table sets forth,  for the named  executive  officers (as defined
below under "Compensation - Summary Compensation  Table"), Mr. Richard P. Dealy,
the Company's Executive Vice President and Chief Financial Officer,  and certain
groups, all Awards granted in 2005 under the 1997 LTIP:

     If the 2006 Plan submitted to  stockholders is not approved by stockholders
at the Annual  Meeting,  the 2006 Plan will not be adopted and no Awards will be
granted under the 2006 Plan.

     The Board of Directors  recommends that  stockholders vote FOR the approval
of the proposed Pioneer Natural Resources Company 2006 Long-Term Incentive Plan.
Because each of the Company's  directors and executive officers will be eligible
to receive Awards under the proposed  plan,  each of the directors and executive
officers of the Company has an interest in, and may benefit  from,  the adoption
of the proposed plan.

                                  COMPENSATION

Compensation of Directors

     The Board of  Directors  believes  providing  competitive  compensation  is
necessary to attract and retain qualified non-employee  directors.  The Board of
Directors  believes that the  compensation  package should require a significant
portion  of the  total  compensation  package  to be  equity  based to align the
interests of the Board of Directors  and the Company's  stockholders  but should
also allow each director the  flexibility  to choose to receive a portion of the
director's  compensation in cash. To maintain competitive director compensation,
the  Compensation  and  Management   Development   Committee  (the  "Committee")
periodically engages a compensation  consultant to conduct a benchmarking review
of outside director pay.

     The elements of compensation for the Company's  non-employee  directors for
the 2005-2006  director year,  which runs from the annual meeting of 2005 to the
annual meeting of 2006, are as follows:

     o    Each  non-employee  director  receives an  annual base retainer fee of
          $40,000 and an  annual  fee of  $10,000  for  service  on one  or more
          committees.
     o    Audit Committee members receive an additional $7,500 annual fee.
     o    The  geosciences  specialist on  the Board  of Directors  receives  an
          additional $7,500 annual fee.
     o    The lead director receives an additional $15,000 annual fee.
     o    The chairman  of the  Audit Committee  receives an  additional  $7,500
          annual fee and  each other committee  chairman  receives an additional
          $2,500 annual fee.

     Additionally, each non-employee director is provided information technology
support by the  Company  and is also  reimbursed  for travel  expenses to attend
meetings of the Board of Directors or its committees,  travel and  entertainment
expenses for each  director's  spouse who is invited to  accompany  directors to


                                       18





meetings  of the Board of  Directors,  director  education,  seminars  and trade
publications.  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.

     Under this  compensation  program,  non-employee  directors are eligible to
receive  their fees in the form of stock  options,  stock  appreciation  rights,
restricted stock,  restricted stock units 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  compensation   each  year,  based  on  the  economic  and  other
circumstances  at the time of award and based on its view of which  awards  will
best align the interests of the  stockholders  and the Board of  Directors.  For
both the 2005-2006 and 2006-2007  director  years,  the  non-employee  directors
could  choose to be  compensated  for their  annual  directors'  fees in (i) 100
percent cash, (ii) 100 percent  restricted  stock units ("RSU") or (iii) a 50/50
combination of any thereof.

     In addition to their annual base pay retainer  fee,  directors  received an
annual equity award of $60,000 in restricted  stock units.  The restricted stock
units vest after one year. Retirement before the first anniversary of the annual
equity award grant  results in pro rata vesting based on the number of quarterly
meetings remaining in the director year.

     New directors  joining the Board of Directors after May 2005 received a pro
rata portion of the $60,000 annual equity award in restricted  stock units based
on the number of quarterly  meetings  remaining in the director year. The number
of shares granted is determined by dividing the value of the equity award by the
closing  price of one share of Company  stock on the last day  preceding the day
the director joins the Board of Directors.

     Each  non-employee  director,  upon  commencement  of initial  service as a
director,  receives $125,000 of restricted stock units.  Directors who served on
the Board of Directors of a company that was acquired or merged into the Company
and joined the Company's  Board of Directors as a result of the  acquisition  or
merger are not eligible for this award.  The price used to calculate  the number
of shares  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. Retirement before the third anniversary of the grant results in pro rata
vesting based on the number of quarterly  meetings  remaining in the  three-year
vesting period.

     The  vesting  of  ownership  and the  lapse  of  transfer  restrictions  on
restricted stock units to non-employee  directors is accelerated in the event of
the death or disability of the director or a change in control of the Company.

(e)  Mr. Risch joined the Board of Directors effective August 10, 2005.



     During 2005,  the  Committee  engaged the services of Hewitt  Associates to
conduct a review of the compensation of its non-employee  directors.  The review
included an  analysis of the  director  compensation  practices  of a peer group
consisting of independent oil and gas exploration and production  companies with
similar asset,  revenue and capital investment profiles as the Company's.  Based
on the results of Hewitt's  benchmarking of the Company's peer group,  the Board
of  Directors  approved the  following  compensation  changes for the  2006-2007
director year, which begins at the Annual Meeting.

         o   Increase the annual retainer from $40,000 to $50,000.
         o   Increase the value of the annual equity based award from $60,000 to
             $80,000.
         o   Increase the  initial equity based  award to attract  new directors
             from $125,000 to $150,000.

Hewitt concluded these changes resulted in total director  compensation  that is
competitive but below the 50th percentile of industry peers.

(c)  The value  of  the  2005  restricted  stock  reported  in this  column  was
     determined using the  February 14, 2005  grant date closing price of $38.97
     per  share  for the  Company's  common  stock as  reported by the NYSE. The
     restricted stock grant includes vesting restrictions that lapse on February
     15, 2008. Holders of restricted stock are entitled to receive dividends, if
     any,  paid on  the Company's  common stock.  Aggregate  unvested restricted
     stock grants as of December 31,  2005 and the corresponding value  based on
     the closing price  of the common  stock as reported on the NYSE on December
     30, 2005 ($51.27 per share) are: Mr. Sheffield, 124,350 shares, $6,375,425;
     Mr. Dove,  44,800 shares,  $2,296,896;  Messrs.  Alameddine,  Cheatwood and
     Kellum 33,750  shares each, $1,730,363 each; and Mr. Dealy,  23,660 shares,
     $1,213,048.
(d)  For 2005,  this column includes (i)  contributions to  qualified retirement
     plans of $21,000 to each of Messrs. Sheffield, Dove, Alameddine, Cheatwood,
     Kellum  and  Dealy;  (ii)  contributions  to  the  Company's  non-qualified
     deferred compensation retirement plan for Mr. Sheffield of $82,500; for Mr.
     Dove of $47,500;  for Messrs.  Alameddine,  Cheatwood and Kellum of $33,000
     each; and for Mr. Dealy of $30,000; and (iii) a $2,860 premium with respect
     to  a  term  life  insurance  policy  for  the  benefit of  Mr.  Sheffield.
(e)  This column  indicates, for  the year presented,  the sum of the values set
     forth  in the  columns  "Salary,"  "Bonus,"  "Other  Annual  Compensation,"
     "Restricted Stock Awards" and "All Other Compensation."

     Two of the Company's  executive  officers,  Mr.  Sheffield and Mr.  Kellum,
directly or indirectly hold working interests in wells of which the Company or a
subsidiary is the  operator.  These  interests  were acquired in 1990 or earlier
with the executive officers' personal funds pursuant to a program offered by the
Company's  predecessor.  As such,  the  holders  participate  in the  costs  and
revenues  attributable  to that working  interest in accordance  with  customary
industry terms.  During 2005, the aggregate amounts of the distributions made to
Messrs. Sheffield and Kellum were $33,806 and $13,249, respectively.

     Long-Term Incentive Plan. The Company's 1997 LTIP provides for employee and
non-employee  director grants in the form of stock options,  stock  appreciation
rights,  restricted  stock,  restricted  stock units or performance  units.  The
maximum  number of shares of common stock that may be issued under the 1997 LTIP
is  equal  to ten  percent  of the  total  number  of  shares  of  common  stock
equivalents  outstanding  from time to time minus the total  number of shares of
stock subject to outstanding  grants on the date of calculation  under any other
stock-based  plan for  employees or directors of the Company.  The 1997 LTIP has
8,127,613 shares available for additional  awards as of March 14, 2006 (compared
to the  4,600,000  shares that will be available  for awards if the 2006 Plan is
adopted).

     The  1997  LTIP  provides  that  awards  may  be  forfeited  or  vested  at
termination of employment  depending on the  circumstances  of  termination  and
whether the participant had a written employment agreement.

     The  1997  LTIP  provides  that  the  Committee  may  determine  whether  a
particular award under the 1997 LTIP will have change in control provisions.  In
general, awards under the 1997 LTIP contain provisions that provide that options
and restricted  stock or restricted stock units will become  immediately  vested
and  exercisable  in full upon a change in control and that  options will remain
exercisable  for their full  original  term  regardless  of whether  and how the
holder's employment is subsequently terminated.

     No stock  options,  stock  appreciation  rights or  performance  units were
awarded under the 1997 LTIP in 2005.  If the  Company's  2006 Plan is adopted at
the Annual Meeting, no further awards will be made under the 1997 LTIP.

(a)  Amounts were  calculated by  multiplying the  number of unexercised options
     by $51.27, which was the  closing price  of the  Company's common  stock on
     December 30, 2005,  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 and a
non-qualified  deferred  compensation  retirement plan for executive officers of
the Company but does not provide defined benefit retirement plans or restoration
plans.  Hewitt  Associates has advised the Company that the  retirement  benefit
value  delivered  through  the  401(k)  retirement  plan  and the  non-qualified
deferred compensation retirement plan is well below the median market retirement
value.

     The  non-qualified  deferred  compensation   retirement  plan  allows  each
participant  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 ten percent of
the executive  officer's base salary. The Company's matching  contribution vests
immediately.  The non-qualified  deferred  compensation plan permits officers to
make investment allocation choices for both the executive officer's contribution
and the Company  match to  designated  mutual funds or  self-directed  brokerage
accounts included in the non-qualified  deferred  compensation plan. The Company
retains  the  right  to  maintain  these  investment   choices  as  hypothetical
investments or to actually invest in the executive officer's investment choices.
To date,  the Company has chosen to actually  invest the funds in the investment
options  selected by the executive  officers so that the investment  returns are
funded and do not create unfunded liabilities to the Company.

     The following table sets forth,  for each named  executive  officer and Mr.
Dealy,  information  as to the fair values of vested  benefits in the  Company's
non-qualified deferred compensation retirement plan through December 31, 2005:

     Participants  may choose to receive  distributions of their vested benefits
from the non-qualified compensation plan as soon as administratively practicable
(i) after the date of  separation  from  service  with the Company or (ii) after
January 1 of the year  following  the date of  separation  from service with the
Company.  Participants vested benefits may, at the option of the participant, be
distributed  in one lump  sum,  in five  annual  installments  or in ten  annual
installments.

     Severance  and  Change  in  Control  Agreements.  The  Company  is party to
severance  agreements  and  change  in  control  agreements  with its  executive
officers.  The  forms  of  severance  and  change  in  control  agreements  were
previously filed as an exhibit to the Company's Current Report on Form 8-K filed
with the  Securities  and Exchange  Commission on August 17, 2005.  Salaries and
bonuses  are  set by the  Committee  independent  of  these  agreements  and the
Committee can increase or decrease base salaries at its discretion.

     On August 16, 2005, the Company  entered into new severance  agreements and
change in control agreements with its executive  officers.  These new agreements
replaced the severance  agreements  (which provided for certain severance rights
both  before  and  after a  change  in  control)  that  the  executive  officers
previously had with the Company.

     The  severance   agreements  provide  that,  if  the  executive  terminates
employment for good reason (which  generally  includes a demotion or significant
pay reduction,  and for Mr. Sheffield also includes his not being reelected as a
director) or if the Company  terminates the employment of the executive  officer
other than for cause, death,  disability or normal retirement,  the Company must
pay the executive officer a separation  payment in addition to earned salary and
vested benefits. The separation payment is an amount equal to the sum of (1) one
times the  executive  officer's  base  salary  (three  times base salary for Mr.
Sheffield and 2.5 times base salary in the case of Mr.  Dove),  (2) 18 times the
monthly  executive  officer's  cost of coverage  for  himself  and his  eligible
dependents under the Company's group medical plans (36 times the monthly cost in
the case of Mr.  Sheffield  and 30  times  the  monthly  cost in the case of Mr.
Dove), and (3) one-twelfth of the executive officer's base salary if the date of
termination  is less than 30 days  following the notice of  termination  and the
executive  officer's  employment is  terminated  by the Company.  In the case of
Messrs.  Sheffield  and Dove,  the  severance  agreements  also  provide for the
immediate vesting of certain awards under the Company's 1997 LTIP. The severance
agreements terminate upon a change in control of the Company.

     The change in control  agreements  provide that,  if the executive  officer
terminates  employment  for good  reason  (which  generally  includes an adverse
change in duties or a reduction in base salary,  target bonus,  equity awards or
benefits) or if the Company  terminates the employment of the executive  officer
other than for cause, death, disability or normal retirement,  in either case in
connection with or after a change in control, the Company must pay the executive
officer a separation  payment and provide  continued group medical  coverage for
approximately three years (in the case of Messrs.  Sheffield and Dove, until the
date the executive is eligible for full medical benefits under the provisions of
Medicare), in addition to paying earned salary and vested benefits. In addition,
all the  executive  officer's  awards under the  Company's  1997 LTIP will fully
vest. The separation payment is an amount equal to the sum of (1) 2.99 times the
sum of the executive  officer's  base salary and target  bonus,  (2) a pro-rated
portion of the target bonus based on the days elapsed in that calendar year, and
(3)  one-twelfth  of  the  executive  officer's  base  salary  if  the  date  of
termination  is less than 30 days  following the notice of  termination  and the
executive  officer's  employment is  terminated  by the Company.  If the Company
terminates an executive  officer without cause  following a potential  change in
control (as defined in the  agreements) and if a change in control occurs within
12 months,  the executive officer will be entitled upon the change in control to
the  payments  that would have been made if the  executive  had  continued as an
executive officer until the change in control,  as well as to a payment equal to
the value of the executive officer's  equity-based awards that did not vest when
his  employment  was  terminated.  If,  after a change in control,  an executive
officer  terminates  employment  because he is required to relocate more than 50
miles,  but is not otherwise  entitled to terminate  employment for good reason,
then the Company must pay the  executive  officer a reduced  separation  payment
equal to his  annualized  base salary,  in addition to earned  salary and vested
benefits,  and  provide  continued  coverage  for one year under  group  medical
benefit  plans.  The change in control  agreements  also obligate the Company to
make the executive  officers  whole (that is,  provide a "gross-up")  for excise
taxes that may be imposed on payments under the change in control  agreements by
Section  4999 of the Internal  Revenue  Code.  The change in control  agreements
continue for two years following a change in control that occurs during the term
of the agreement.  For illustrative purposes, based on his current compensation,
the separation  payment payable to Mr.  Sheffield upon a change in control would


                                       24





be the sum of (i) $5,083,000,  plus (ii) a pro rata portion of his $850,000 2006
target  bonus  based on the days  elapsed  in that  calendar  year,  plus  (iii)
$70,833,  if the  date of  termination  is less  than 30 days  following  notice
thereof.

     Both the severance  agreements and the change in control agreements provide
for a payment of one times the executive  officer's  base salary in the event of
his death, disability or retirement.

     Indemnification  Agreements.  The Company has entered into  indemnification
agreements  with  each of its  directors  and  executive  officers.  The form of
indemnification  agreement was  previously  filed as an exhibit to the Company's
Current Report on Form 8-K filed with the Securities and Exchange  Commission on
August  17,  2005.  Each  indemnification  agreement  requires  the  Company  to
indemnify  each  indemnitee  to the fullest  extent  permitted  by the  Delaware
General  Corporation Law. This means, among other things,  that the Company must
indemnify  the  director  or  executive  officer  against  expenses   (including
attorneys'  fees),  judgments,  fines and amounts  paid in  settlement  that are
actually and reasonably  incurred in an action,  suit or proceeding by reason of
the fact that the person is or was a director, officer, employee or agent of the
Company or is or was  serving  at the  request  of the  Company  as a  director,
officer,  employee  or agent of  another  corporation  or  other  entity  if the
indemnitee  meets the  standard of conduct  provided in  Delaware  law.  Also as
permitted under Delaware law, the indemnification agreements require the Company
to advance  expenses in defending  such an action  provided that the director or
executive  officer  undertakes to repay the amounts if the person  ultimately is
determined not to be entitled to indemnification  from the Company.  The Company
will also make the  indemnitee  whole for taxes  imposed on the  indemnification
payments  and for  costs  in any  action  to  establish  indemnitee's  right  to
indemnification, whether or not wholly successful.

     Directors'  and  Officers'  Insurance.   The  Company  maintains  customary
directors' and officers' insurance coverage.

                COMPENSATION AND MANAGEMENT DEVELOPMENT COMMITTEE
                      INTERLOCKS AND INSIDER PARTICIPATION

     During  2005,  no member of the  Compensation  and  Management  Development
Committee also served as an executive officer of the Company. During 2005, there
were no Compensation and Management  Development Committee interlocks with other
companies.

                COMPENSATION AND MANAGEMENT DEVELOPMENT COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION

     The information  contained in this Compensation and Management  Development
Committee  Report on  Executive  Compensation  and in the  section of this Proxy
Statement  entitled "Company  Performance" shall not be deemed to be "soliciting
material" or to be "filed" with the  Securities  and  Exchange  Commission,  nor
shall such information be incorporated by reference into any future filing under
the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the
extent that the Company specifically incorporates such information.

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

     The Committee is responsible for  establishing  all components of executive
pay, reviewing the performance of the Company's executive officers and approving
all  compensation  awards  for  all  executive  officers,  including  the  named
executive  officers.  The  Committee  approves all long-term  incentive  awards,
benefits and perquisites.  The Committee also reviews the leadership development
process to assure the proper  emphasis in being placed on  executive  succession
planning. The Committee operates under a written charter adopted by the Board of
Directors.  A copy of the current charter is posted on the Company's  website at
www.pxd.com.   Members  of  the  Committee  are:  Messrs.   Edison  C.  Buchanan
(Chairman), James R. Baroffio, Andrew D. Lundquist and Charles E. Ramsey, Jr.


                                       25






Compensation Principles and Philosophy

     The   overriding   responsibility   of  the  Committee  is  to  maintain  a
compensation  program that  attracts and retains a capable and highly  motivated
senior  management team and aligns the  compensation of the Company's  executive
officers with the  Company's  strategic  business  plan to increase  stockholder
value.  The  Committee  strongly  believes  it  is  important  to  evaluate  the
performance of the Company and executive officers each year, in light of oil and
gas  industry  fundamentals,  and assess how  effectively  management  adapts to
changing industry  conditions and  opportunities  during the year. The Committee
does not believe  formula-based  variable-pay plans effectively drive successful
performance  for  executives  of  companies  in the oil and  gas  industry.  The
Committee  also believes the portion of an employee's  total  compensation  that
varies with  individual,  team and Company  performance  should increase as that
employee's  scope,  duties and  responsibilities  increase.  The  Committee  has
structured the annual bonus and long-term  incentive  awards to be a significant
portion of an executive  officer's total compensation so that total compensation
is reflective of both the executive officer's individual performance, as well as
the Company's overall performance.

     Beginning in 2004, the Committee  elected to change the nature of long-term
incentive equity awards from a combination of stock options and restricted stock
to grants of restricted  stock determined by the Committee with reference to the
recipient's performance, in order to further emphasize performance and alignment
of stockholders' and executive officers' interests.  The Committee has adopted a
policy of not  re-pricing  stock options and  incorporated  that policy into the
Company's 1997 LTIP.

Other critical  elements of the Company's  compensation  and incentive  policies
provide for:

    o   Base salaries  at or  near median  levels compared  to  industry  survey
        information and peer group proxy analysis.
    o   Annual bonus target levels at  or near median levels  with payouts above
        or below target based on both individual and Company performance.
    o   Long-term  incentive  target  award  levels  that are at or  near median
        levels  with the actual  awards  above  or below  target  based  on both
        individual and Company performance.
    o   Significant stock ownership by  directors,  the  Chief Executive Officer
        and all other executive officers.

     To assist the Committee in its efforts to establish  and  administer a fair
and competitive compensation program, consistent with the Company's compensation
philosophy,  the  Committee  has  directly  engaged  Hewitt  Associates  as  the
Committee's   compensation  consultant  to  conduct  a  benchmarking  review  of
compensation levels for the Chief Executive Officer and other executives.  Using
sound and  consistent  methodologies,  the  consultant  collects and  summarizes
compensation  data for a  predefined  peer  group.  The peer group  consists  of
independent oil and gas exploration and production companies with similar asset,
revenue and capital  investment  profiles as the Company.  Hewitt Associates has
developed  competitive market references for base salary,  annual incentives and
long-term  incentives  (including all forms of equity compensation) based on the
Company's compensation philosophy. Prevalent practices for supplemental benefits
and perquisites are also documented.

     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 five times each
        director's annual  base retainer  fee.  The non-employee  directors have
        three years after joining the Board of Directors to meet the guideline.
    o   Chairman of the  Board of Directors  and Chief  Executive  Officer stock
        value equal to at least five times his annual base salary.
    o   President  and other  named  executive  officers stock value equal to at
        least three  times their  annual base  salary.  The president  and other
        named executive officers, generally,  have three years after becoming an
        officer to meet the guideline.


                                       26





     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. All named executive  officers,  including Mr. Sheffield,
and all non-employee directors are in compliance with the ownership guidelines.

     The Omnibus Budget  Reconciliation  Act of 1993 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" as required in Section 162(m)
of the Internal Revenue Code of 1986, as amended. Non-deductibility could result
in  additional  tax  costs to the  Company.  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.  The Company's annual incentive bonus plan does not
meet the  definition of  performance-based  compensation  as required in Section
162(m)  primarily  because the annual incentive bonus plan is not formula driven
and  the  Committee  retains  the  right  to  make  subjective   evaluations  of
performance  including an assessment  of how  effectively  management  adapts to
changing industry conditions and opportunities  during the Company's bonus year.
Pioneer's   restricted   stock  awards  do  not  qualify  as   performance-based
compensation  under Section  162(m).  Accordingly,  the portions of compensation
paid to our named  executive  officers in 2005 that exceeded  $1,000,000  (other
than from the  exercise of stock  options) are  generally  not  deductible.  The
Committee believes it is in the best interest of stockholders to continue with a
discretionary  element  in the  annual  incentive  bonus  program  and  to  make
performance  share  awards  in the form of  restricted  stock  to the  Company's
officers instead of stock options. The Committee is studying long-term incentive
plan  alternatives  that will qualify as  performance-based  compensation  under
Section 162(m).

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  1997  LTIP,
contributions  to the Company's  401(k)  retirement  plan,  contributions to the
Company's  non-qualified 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  including  benefits and perquisites  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
near the median  level for  companies  with  similar  business  strategies.  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,
internal pay equity,  and  consideration of each officer's  experience,  duties,
responsibilities  and knowledge.  The Committee  views the executives  below the
Chief  Executive  Officer  level as a team with diverse  duties but with similar
authority  and   responsibility  and  factors  this  team  approach  into  final
determination  of base pay.  The  Committee  determines  the base salary for all
officers, including Mr. Sheffield, using the same methodology.

     For 2006, Mr. Sheffield's annual base salary was increased from $825,000 to
$850,000.  Hewitt Associates  determined that Mr. Sheffield's annual base salary
is below  the 50th  percentile  level.  The base  salaries  of the  other  named
executive  officers  were  increased  for 2006 to levels that Hewitt  Associates
advises, as a group, are at or near the 50th percentile.

     Annual Bonuses.  The Company's  annual bonus program is designed to provide
added  incentive  for  executives  to  achieve  specific  goals  that  have been
communicated to be of primary importance during the current year. Actual payouts
can vary above or below the target levels based on the Committee's evaluation of
Company and individual  performance  against  corporate and individual goals and
the  competitive  conditions  within the oil and gas  exploration and production
industry.  Each year the Committee establishes a target bonus for each executive
officer based on the target bonus median levels of executive officers in similar
positions at peer group companies.


                                       27






     To  maintain  internal  equity,  the  level of  responsibility,  scope  and
complexity of the executive  officer's  position are considered.  Awards for the
annual  incentive  bonus  plan can range from 0 to 200  percent  of  target.  In
awarding 2005 bonuses,  the Committee reviewed criteria,  such as the following,
that are important to the success of the Company's business plan:

    o    Net asset value per share
    o    Return on equity
    o    Operating cost per barrel of oil equivalent ("BOE")
    o    Debt/Book capitalization
    o    Investment grade credit ratings
    o    Reserve replacement
    o    Finding and development cost per BOE
    o    Production growth
    o    General and administrative costs per BOE
    o    Growth of share value
    o    Safety and environmental performance

     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 or  predetermined  weighting of the above
financial and operational  performance criteria,  but did compare actual results
to target goals. 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 stock performance in relation
to its peers, the Company's performance in achieving its goals and the strategic
direction provided to the Company.  Regarding the award of Mr. Sheffield and Mr.
Dove's  bonuses,  the  Committee  considered  the factors of net asset value per
share and stock price performance  versus the peer group as the most significant
criteria.

     For 2005, the target bonuses for the named executives  ranged from 65%-100%
of base salary.  The 2005 target bonus levels for the named  executive  officers
were  identified by Hewitt  Associates as being slightly above the median level.
Following  a thorough  review of the  Company's  results  versus its goals,  the
Committee  concluded that the Company produced good results in light of industry
and external  influences and awarded Mr.  Sheffield,  the other named  executive
officers and Mr. Dealy a cash bonus above the target  level.  In addition to the
above stated criteria,  the Committee considered the successful execution of the
changes  to  strategic   direction  that  were  initiated   during  2005.   This
consideration  included the preparation for divestitures of non-strategic assets
in Argentina and the  deepwater  Gulf of Mexico and the progress of the internal
business  realignment  plan  for  most  effectively  allocating  capital  to the
higher-return  North American  development  opportunities  and emerging resource
plays that are the focus of the new strategy.

     Overall costs were appropriately  managed in light of the surge in industry
service costs and production levels met  expectations.  Finding cost and reserve
replacement  goals were not achieved,  but the Company took significant steps to
improve these results going  forward  through the strategic  changes  previously
discussed.  The Company  provided a strong return on equity and  acceptable  net
asset  value  per  share   performance  and  further  enhanced  its  safety  and
environmental  record.  While slightly below average  compared to the peer group
and the industry, the Company's stock price increased significantly.

     Actual basic  payouts for bonuses  since 1997 have ranged from a low of 75%
to a high of 185% of target bonus, with 2005 basic payouts being 115% of target.
The basic  payout  percent  is  determined  by Company  performance.  Individual
performance  determines  whether an executive  officer  receives  bonus above or
below the basic payout  percent.  The 2006 target bonus percent  established for
Mr.  Sheffield and the other named executive  officers did not change from 2005.
Mr. Dealy's target bonus level increased from 65% to 70%.

     Long-Term Equity Incentives. The Company's 1997 LTIP is designed to balance
the focus of attaining short-term annual results with achieving long-term three-
to five-year goals that will create long-term value for  shareholders.  The 1997
LTIP also allows the Company to deliver the majority of an  executive  officer's
pay  as  performance-based/variable   compensation.  The  target  value  of  the
long-term  incentive  awards  for Mr.  Sheffield  in 2005  was  determined  by a
comparison of long-term incentive grants made to the Chief Executive Officers of
peer group  companies.  The target value of long-term  incentives  for the named
executive  officers was  determined by comparing the value of awards  granted to

                                       28





peer company  executives  holding similar positions and their individual targets
reflecting  an  averaged  approach  to take  into  consideration  the  Company's
executive team approach to provide leadership to the Company.

     The award levels were not  influenced by the current stock  holdings of the
executive  officers.  The  Company's  philosophy  has been to  target  long-term
incentives with values that are near the 60th percentile  level relative to peer
group  companies.  During  2005,  Mr.  Sheffield  was awarded  63,000  shares of
restricted  stock.  Hewitt  Associates  concluded  the 2005  awards  placed  Mr.
Sheffield and the other named executive officers as a group at approximately the
60th  percentile  level for  long-term  incentive  awards  among the peer group.
Beginning with the 2007 awards,  the Company has changed its philosophy and will
target long-term incentive awards at or near the 50th percentile level, in order
to avoid the potential of inflating  targeted total compensation above the point
of being at or near the median of the market.

     To achieve alignment with shareholders and emphasize long-term performance,
the Committee determines share awards under the Company's 1997 LTIP by reference
to the  performance  of the  recipient.  No stock  options  were  awarded to Mr.
Sheffield or the other executive officers for 2005.  Restricted stock awarded to
the  executive  officers  under this  program  has a  three-year  cliff  vesting
requirement.

     The number of restricted shares awarded each year as a percentage of target
award  levels is  determined  by a  three-step  process.  First,  the  Committee
conducts a subjective evaluation of the internal Company performance against the
following metrics over three- and five-year periods:

    o    Production growth
    o    Reserve replacement
    o    Finding and development cost per BOE
    o    Net asset value per share
    o    Debt statistics

     Next,  to finalize the award level for the executive  group,  the Committee
considers the Company's total  shareholder  return results compared to the total
shareholder  return results of the Company's peer group for the previous  three-
and five-year  period.  Finally,  the  Committee  conducts an evaluation of each
executive's  individual  performance and considers total compensation  values to
determine if the  long-term  award should be adjusted so total  compensation  is
competitive  but not excessive.  For 2006, the Committee  awarded Mr.  Sheffield
61,000 shares of restricted  stock,  which was near the 60th percentile level as
reported by Hewitt Associates. The Committee considered and was pleased with Mr.
Sheffield's  leadership of the Company,  the Company's five-year results and the
execution of the changes to strategic direction that were initiated during 2005,
including  the  preparation  for the  divestitures  of  non-strategic  assets in
Argentina  and the  deepwater  Gulf of  Mexico  and the  progress  of plans  for
allocating capital to onshore North American  opportunities.  The Committee also
determined Mr. Sheffield's total compensation, including retirement benefits and
perquisites, was below the median level for peer group companies.

     Other  Compensation.  In  addition  to base  salaries,  annual  bonuses and
long-term  incentive  awards,  the  Committee  reviews  all other  benefits  and
perquisites  to  determine  if the  total  compensation  package  for  executive
officers is fair, reasonable and competitive. Hewitt Associates has reviewed the
Company-provided benefits and perquisites and concluded that the Company's total
retirement value provided to executive officers is well below market,  since the
Company does not provide a pension plan or a Supplemental  Executive  Retirement
Plan, and the Company's  perquisite  offerings are conservative  compared to the
market.

     The  Company  maintains  a  fractional  ownership  interest  in two private
aircraft.  These  aircraft are made  available for business use to the executive
officers  and  other  employees  of the  Company.  The  Company's  policy  is to
generally  not  permit  employees,  including  executive  officers,  to use  the
aircraft for personal use. The Company  expects  there will be occasions  when a
personal guest will accompany an employee on a business related flight.  In such
instances, the Company will follow the Internal Revenue Service rules and, where
required,  impute  income to the employee  based on the Standard  Industry  Fare
Level rates provided by the Internal Revenue Service.

     Severance and Change in Control  Agreements.  The Company  decided to enter
into  new  severance  agreements  and  change  in  control  agreements  with its
executive officers after a general review of its severance and change in control

                                       29





arrangements,  performed during early 2005 by the Committee.  In connection with
its  review,  the  Committee  engaged  advisors  knowledgeable  in the  field of
executive  compensation  to assist it in  analyzing  current  market  practices.
Competitive  agreements  are critical in order to recruit and retain  executives
and provide  continuity  of  management  in the event of an actual or threatened
change in control.  The primary goals of the new agreements  were to standardize
the agreements within the Company (including by reducing the number of different
forms used for executives and  non-executive  personnel) and provide  protection
for officers consistent with the Company's  perception of market practices after
considering the views of its advisors.

     Total Chief Executive Officer Compensation.  All compensation  arrangements
for Mr.  Sheffield  and the  named  executive  officers  have been  tallied  up,
reviewed  with the  Company's  compensation  consultant  and  deemed to be fair,
competitive and not excessive.  Mr.  Sheffield's total compensation is deemed to
be slightly below the median level.

     Mr.  Sheffield's  total  compensation  paid  by the  Company  for  2005  is
summarized below:


                                                     
             Base pay.................................     $    825,000
             Annual bonus (a).........................          948,750
             Long-Term Incentive awards (b)...........        2,455,110
             Retirement plan contributions (c)........          103,500
             Other perquisites (d) (e)................           37,132
                                                           ------------
                 Total................................     $  4,369,492
                                                            ===========

-----------
(a)  Represents the amount awarded under the Company's annual bonus program that
     was paid during the three months ended March 31, 2006.
(b)  Based on grant date closing  price of $38.97 of  restricted  stock  awarded
     during 2005.
(c)  401(k) plan and non-qualified deferred compensation retirement plan.
(d)  Includes the estimated costs of life insurance,  country club dues, officer
     physical,  financial consulting service,  travel and entertainment costs of
     Mr.  Sheffield's  spouse,  and miscellaneous  personal use of a cell phone,
     computer and computer-related utilities provided for business use.
(e)  Does not include a value for all other  broad-based  benefits  available to
     all employees.



     In  summary,  the  Company  believes a  significant  portion  of  executive
compensation  should be  variable  and  performance-based  so that an  executive
officer'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.

     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 Audit  Committee has reviewed and
discussed the audited  financial  statements with management and the independent
auditors.  The Audit 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 Audit Committee
has  received  the  written  disclosures  and the  letter  from the  independent
auditors  required by Independence  Standards Board Standard No. 1,  Independent
Discussions with Audit Committees,  as currently in effect.  The Audit 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 Audit  Committee
Report, and subject to the limitations on the roles and  responsibilities of the
Audit  Committee  referred  to below and in the  charter,  the  Audit  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, 2005,
for filing with the SEC. The Audit Committee has also selected Ernst & Young LLP
as the Company's independent auditors for 2006.

     Although  determined  to be  financially  literate  (as  defined by the SEC
rules), the members of the Audit 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 Audit Committee rely,  without
independent  verification,  on  the  information  provided  to  them  and on the
representations  made by management and the independent  auditors.  Accordingly,
the  Audit  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 Audit 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.  The Company's Corporate  Governance  Principles as adopted by the
Board of Directors, covers 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.pxd.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.pxd.com/governance.  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 standards for determining  director  independence require the
assessment of directors' independence each year. A director cannot be considered
independent  unless the Board of Directors  affirmatively  determines that he or
she does not have any  relationship  with  management  or the  Company  that may
interfere with the exercise of his or her independent judgment, including any of
the  relationships  that would  disqualify  the director from being  independent
under the rules of the NYSE.  As  contemplated  by the NYSE rules,  the Board of
Directors  has also  adopted  categorical  standards  to assist  in  determining
whether any material  relationship  with the Company or its  management  exists.
Directors  who  have  any  of the  relationships  outlined  in  the  categorical
standards  are  considered  to have  relationships  that  require  the  Board of
Directors'  review of the full  facts and  circumstances  in order to  determine
whether  the  relationship  impairs  the  independence  of  the  director.   The
categorical  standards  are set forth under  "Independence  of Directors" in the
Company's Corporate Governance Principles and are:

1.   the director has no material relationship with the Company, either directly
     or as a  partner,  shareholder  or officer  of an  organization  that has a
     relationship with the Company;
2.   the director, or any member of the director's family, has not been employed
     by the Company in the last three years;
3.   the director, or any member of the director's family, has not been employed
     by, or affiliated with, the Company's auditor in the last three years;
4.   the director,  or any member of the director's family, has not been part of
     an interlocking directorate in the last three years;
5.   the  director,  or any member of the  director's  family,  has not received
     non-director fee compensation from the Company in the last three years;


                                       32





6.   the director is not an executive officer or employee,  or any member of the
     director's  family is not an  executive  officer,  of a company  that makes
     payments to, or receives payments from the Company for property or services
     in an amount which,  in any single  fiscal year,  exceeds the greater of $1
     million or 2% of such other  company's  consolidated  gross revenues in the
     last three years;
7.   the director does not own more than 4.9 percent of the Company's shares;
8.   the director does not serve on more than three other public company boards;
     and
9.   the director does not serve on the board of another oil and gas exploration
     and production company.

     In May 2005,  the Board of  Directors  assessed  the  independence  of each
non-employee director under the Company's  guidelines.  In August 2005, upon Mr.
Risch's   appointment  as  director,   the  Board  of  Directors   assessed  the
independence of Mr. Risch under the Company  guidelines.  The Board of Directors
affirmatively  determined that all eleven non-employee  directors (Dr. Baroffio,
Mr. Buchanan,  Mr. Gardner,  Mr. Jones, Mrs. Lawson, Mr. Lundquist,  Mr. Ramsey,
Mr. Risch, Mr. Sexton, Mr. Solberg and Mr. Watson) are independent.

     The  Board  of  Directors  reviewed  the  facts  and  circumstances  of Mr.
Lundquist's  and Mr.  Sexton's  interests in the Company's  2004  acquisition of
Evergreen, of which Mr. Lundquist was an independent director and Mr. Sexton was
the Chairman of the Board, President and Chief Executive Officer, as well as Mr.
Sexton's  payments under his change in control  agreement with Evergreen and his
non-competition  agreement  with the Company.  The Board of Directors  concluded
that Mr. Lundquist's economic interest in the Evergreen  transaction was limited
to his  holdings  as a  security  holder  and that his  prior  activities  as an
independent  director  of  Evergreen  would not  impair  his  independence  as a
director of the Company.  The Board of Directors  similarly  concluded  that Mr.
Sexton is an independent director because Mr. Sexton ceased to be an employee of
Evergreen  at the time of the  merger,  because  his  economic  interest in that
transaction  existed as an employee and  stockholder of Evergreen (both of which
ceased at the merger or upon settlement of the dispute relating to the amount of
change in control  payments  due him  because of the  merger),  and  because the
payment for his new  non-competition  agreement and his  continuation  of health
care and other  insurance  benefits for two years  following  the merger did not
constitute  payment for services to the Company  since it was not  contingent on
continuing service.

     The Board of Directors  also  reviewed the facts and  circumstances  of Mr.
Jones'  relationship  with a law firm from which he had retired in January  1998
and in which he holds the title "of  counsel."  Because Mr. Jones has no role in
or economic  interest in that firm and receives payments only under a retirement
savings  plan,  the  Board  of  Directors  concluded  that  Mr.  Jones'  limited
relationship  with that firm was not  material  and that it would not impair his
independent judgment.

     In connection with its assessment of the independence of each  non-employee
director,  the Board of Directors also  determined that each member of the Audit
Committee  meets  the  additional  independence  standards  of the  NYSE and SEC
applicable to members of the Audit Committee.  Those standards  require that the
director  not be an  affiliate  of the Company and that the director not receive
from the Company,  directly or  indirectly,  any  consulting,  advisory or other
compensatory fees except for fees for services as a director.

Election of Lead Director

     In May 2005, the Board of Directors  reelected Mr.  Ramsey,  a non-employee
director,  to serve as the Lead Director,  meaning he is chairman of the regular
private  meetings  of  the  independent  directors  and of  the  Nominating  and
Corporate  Governance  Committee.  Utilizing input from all directors,  the Lead
Director (i) works with the Chief Executive  Officer (the "CEO") and Chairman of
the Board of Directors  to  determine  the  appropriate  agenda and  information
package for Board of Director meetings;  (ii) meets with the CEO and Chairman of
the Board of Directors, senior management and individual directors, as required,
to facilitate  effective  communications  and  information  flow;  (iii) takes a
leadership  role in CEO succession and executive  management  development;  (iv)
takes a leadership role in director evaluation, continuing education, recruiting
and  orientation;  and (v) serves as the Board of Directors'  contact for direct
employee and stockholder communications with the Board of Directors.


                                       33





Financial Literacy of Audit Committee and Designation of Financial Experts

     In May 2005,  the Board of  Directors  evaluated  the  members of the Audit
Committee for financial  literacy and the attributes of a financial  expert.  In
August 2005,  upon Mr. Risch's  appointment as a member of the Audit  Committee,
the Board of  Directors  evaluated  Mr.  Risch 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 Risch) are  financial
experts as defined by the SEC.

Attendance at Annual Meetings

     The Board of  Directors  encourages  all  directors  to attend  the  annual
meetings of stockholders, if practicable. All of the directors attended the 2005
Annual Meeting of Stockholders held on May 11, 2005.

Procedure for Directly Contacting the Board of Directors and Whistleblower
Policy

     A means for  stockholders  and  employees to contact the Board of Directors
directly  (including the Lead Director) has been established and is published on
the Company's website at www.pxd.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.  All  complaints  and  concerns  will be  received  and  processed  by the
Company's  Corporate  Secretary's  Office.  Complaints relating to the Company's
accounting, internal accounting controls or auditing matters will be referred to
the Audit  Committee of the Company's Board of Directors and other concerns will
be  referred  to  the  Lead  Director  of  the  Company's  Board  of  Directors.
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  Darin G.  Holderness,  the
Company's Vice President and Chief Accounting  Officer,  did not timely file one
report on Form 4 covering one  transaction  effected  during  2005.  The Company
believes that all other required reports were timely filed during 2005.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     In 2004, the Company acquired Evergreen in a merger.  Before the completion
of the merger, Mark S. Sexton was Evergreen's Chairman of the Board,  President,
and Chief Executive  Officer.  Under the terms of Mr. Sexton's change in control
agreement with  Evergreen,  the Company is providing Mr. Sexton  continuation of

     Any  stockholder of the Company who desires to submit a proposal for action
at the 2007 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  4, 2006,  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.


                                       37





     Any  stockholder of the Company who desires to submit a proposal for action
at the 2007  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 19,
2007,  unless the Company  notifies the  stockholders  otherwise.  If a Non-Rule
14a-8  Proposal is not  received by the Company on or before  February 19, 2007,
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  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.

     In identifying potential director candidates,  the Nominating and Corporate
Governance  Committee relies on any source available for the  identification and
recommendation  of  candidates,  including  current  directors and officers.  In
addition,  the Nominating and Corporate  Governance  Committee from time to time
will engage a third party  search  firm to  identify or  evaluate,  or assist in
identifying or evaluating potential candidates, for which the third party search
firm will be paid a fee.

     The  Nominating and Corporate  Governance  Committee will also consider any
nominee  recommended  by  stockholders  for  election  at the annual  meeting of
stockholders to be held in 2007 if that nomination is submitted in writing,  not
later than  December  4,  2006,  to the  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

                                       38





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
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 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.

                                     ANNEX A

                        PIONEER NATURAL RESOURCES COMPANY
                    AUDIT COMMITTEE OF THE BOARD OF DIRECTORS
                                     CHARTER

I    Purpose

     The Board of Directors (the "Board") of Pioneer Natural  Resources  Company
(the "Company") has  established  the Audit  Committee (the  "Committee") of the
Board.  The purposes of the Committee are to assist the Board in fulfilling  its
oversight responsibilities by:

     A.    overseeing the  reliability and integrity  of the Company's financial
           statements,   accounting   policies,  and   financial  reporting  and
           disclosure practices,

     B.    overseeing  the  Company's  compliance  with  legal  and   regulatory
           requirements,

     C.    overseeing the independent auditor's qualifications and independence,

     D.    overseeing the  performance of the  Company's internal audit function
           and any independent internal auditors,

     E.    overseeing  the  Company's  systems of  internal  controls  regarding
           finance, accounting, legal compliance and  ethics that management and
           the Board have established,

     F.    reviewing  and  appraising  the   audit  efforts  of  the   Company's
           independent  auditors and  internal auditing department (reference to
           internal auditors  or the internal audit  department in  this Charter
           shall include both internal audit activities  and functions conducted
           by employees of the Company or  by outside auditors engaged  for such
           purposes) and,  where appropriate, replacing the independent auditors
           or internal audit department,

     G.    providing  an open  avenue of  communication  among  the  independent
           auditors, financial  and senior management,  the internal auditors or
           department, and  the Board,  always  emphasizing that the independent
           auditors are ultimately  accountable to the Committee and  the Board,
           and

     H.    preparing annually  the report  the SEC  rules require be included in
           the  proxy  statement  relating  to the  Company's annual  meeting of
           stockholders, and

     I.    performing such other duties as are directed by the Board.

Consistent  with  this  Purpose,   the  Committee  should  encourage  continuous
improvement  of,  and  should  foster  adherence  to,  the  Company's  policies,
procedures and practices at all levels.  The Committee  will  primarily  fulfill
these responsibilities by carrying out the activities enumerated in Section V of
this Charter.

II   Composition

     The Committee shall be comprised of three or more Directors,  as determined
by the Board or a nominating  committee  of the Board,  none of whom shall be an
affiliate  of  the  Company  or  an  employee  or  a  person  who  receives  any
compensation  from the  Company  other than fees paid for service as a Director.
The  members of the  Committee  shall be  elected  by the Board or a  nominating
committee of the Board annually and shall serve until their  successors shall be
duly elected and qualified.  Each member shall be  "independent" as defined from
time to time by the  listing  standards  of the New  York  Stock  Exchange  (the
"NYSE") and by applicable  regulations of the Securities and Exchange Commission
(the "SEC") and shall meet any other applicable independence requirements of the
NYSE and SEC.  Accordingly,  the Board shall  determine  annually  whether  each
member  is free  from  any  relationship  that  may  interfere  with  his or her
independence from management and the Company.  No member shall serve on an audit

                                      A-1





committee of more than two other public  companies  unless the Board  determines
that such simultaneous  service would not impair the ability of such director to
effectively serve on the Committee.

     Each  member  shall be (or shall  become  within a  reasonable  time  after
appointment) financially literate, and at least one member shall be a "financial
expert"  as  defined  from time to time by  applicable  regulations  of the SEC.
Members  of the  Committee  may  enhance  their  familiarity  with  finance  and
accounting  principles by participating in educational programs that the Company
or an outside consultant conducts.

     Notwithstanding  the foregoing  membership  requirements,  no action of the
Committee  shall be invalid by reason of any such  requirement  not being met at
the time such action is taken.

III  Meetings and Structure

     The  Committee  shall  meet at least  four  times  per year to  review  the
financial   information  of  the  Company,   consistent   with  its  duties  and
responsibilities, and as many additional times as the members deem necessary. As
a part of its effort to foster open communications, the Committee should meet at
least  annually  with  management,   the  director  of  the  internal   auditing
department,  and the  independent  auditors  in separate  executive  sessions to
discuss any matters that the Committee or each of these groups believe should be
discussed privately.

     Unless the Board  designates a Chair of the  Committee,  the members of the
Committee shall, by majority vote of the full Committee membership,  appoint one
member of the  Committee  as  chairperson.  He or she shall be  responsible  for
leadership of the Audit  Committee,  including  preparing the agenda,  presiding
over the meetings,  making committee assignments and reporting to the Board. The
chairperson will also maintain regular liaison with the Chief Executive Officer,
the Chief Financial Officer, the lead audit partner of the Company's independent
auditors and the Company's internal auditor.

IV   Accountability of the Independent Auditors

     The independent  auditors are  accountable to the Committee.  The Committee
shall have the sole authority and responsibility  with respect to the selection,
engagement,   compensation,   oversight,   evaluation  and,  where  appropriate,
dismissal of the Company's  independent  auditors.  The  Committee,  or a member
thereof,  must pre-approve any non-audit  service provided to the Company by the
Company's independent auditors.

V    Authority and Responsibilities

     The  Committee  shall  have  the  authority  to take all  actions  it deems
advisable to fulfill its  responsibilities  and duties. The Committee shall have
the authority to retain  professional  advisors  including,  without limitation,
special legal counsel,  accounting  experts,  or other consultants to advise the
Committee,  which may be the same as or  different  from the  Company's  primary
legal counsel,  accounting  experts and other consultants as the Committee deems
necessary  or  advisable  in  connection  with the  exercise  of its  powers and
responsibilities as set forth in this Audit Committee Charter, all on such terms
as the Committee  deems  necessary and advisable.  The Committee may require any
officer or  employee of the Company or any of its  subsidiaries,  the  Company's
outside legal counsel,  and the Company's  external auditors to attend a meeting
of the Committee or to meet with any member of, or consultant to, the Committee.
The Committee  chairperson,  or other designee of the  Committee,  may also meet
with the  Company's  investment  bankers or  financial  analysts  who follow the
Company.

     The Committee shall be responsible for the resolution of any  disagreements
between  the  independent   auditors  and  management  regarding  the  Company's
financial reporting.

     The Company shall  provide for  appropriate  funding,  as determined by the
Committee,  for payment of compensation to the independent  auditors employed by
the Company for the purpose of  rendering  or issuing an audit report and to any
special legal counsel,  accounting experts or other consultants  employed by the
Committee.


                                      A-2





     To further  fulfill  the  purpose,  powers and  responsibilities  set forth
above, the Committee shall also:

           o   Annually  select and  engage the  Company's independent  auditors
               retained to  audit the financial  statements of  the Company with
               such  selection  to   be  submitted   to  the  stockholders   for
               ratification, if the Board of Directors so chooses.

           o   Review the  performance of  the independent  auditors and approve

           o   Review and  pre-approve the  plan and  scope  of the  independent
               auditors'   auditing  services   (including   comfort   letters),

               any non-audit  services approved  by the  Audit  Committee in the
               Company's periodic reports filed with the SEC.

           o   Ensure that the lead audit partner and reviewing audit partner of

               auditors  regarding all  relationships  between  the  independent
               auditors  and  the   Company  that   may  affect  the independent
               auditors' objectivity  and independence,  and discuss  the report
               with the independent auditors. The Committee shall also recommend
               any appropriate  action to  the Board  in response to the written
               report  necessary  to  satisfy  itself  of  the  independence and
               objectivity of the independent auditors.

           o   Periodically  obtain  and review  reports  from  the  independent

               ("GAAP")   that  have  been  discussed  with   management,  their
               ramifications and the preferences  of the  independent  auditors,
               and  (ii)  other  material  written  communications  between  the

           o   Periodically  obtain  and  review  reports  from  the independent
               auditors  that  include  all  critical  accounting  policies  and

               significant deficiencies in the  design or operation of  internal
               controls which  could adversely affect  the Company's  ability to
               record, process, summarize, and report financial data.

           o   Review  with   management  and   the  independent   auditors  any
               significant  transactions  that  are  not  a  normal part  of the
               Company's  operations  and  changes,  if  any, in  the  Company's
               accounting principles or their application.

           o   At least annually,  obtain and review a report by the independent
               auditors  describing   the   firm's   internal    quality-control
               procedures;  any  material  issues  raised  by  the  most  recent
               internal quality-control review, or peer review,  of the firm, or
               by any inquiry or investigation  by governmental or  professional
               authorities, within the preceding  five years,  respecting one or
               more independent  audits  carried out  by the firm, and any steps
               taken to deal  with any such issues.

           o   Periodically  meet and  review  with  the  Director  o f Internal
               Auditing the regular  internal reports to management  prepared by
               the internal  auditing department  and the progress of activities
               and any findings of  major  significance stemming  from  internal
               audits.

     C.    Financial Reporting Processes

           o   Periodically discuss separately with management,  the independent
               auditors and the internal  auditors the adequacy and integrity of
               the Company's  accounting  policies and  procedures and  internal
               accounting  controls,   the  completeness  and  accuracy  of  the
               Company's  financial  disclosure and the  extent to  which  major

                                      A-4





               recommendations made by the  independent auditors or the internal
               auditors have been implemented or resolved.

           o   Consider  and  approve,  if  appropriate,  major  changes  to the
               Company's  auditing and  accounting  principles and  practices as
               suggested  by  the  independent  auditors,   management,  or  the
               internal auditing department.

           o   Review  with  the  independent  auditors,  the  internal auditing
               department and management the extent  to which such  changes have
               been  implemented.  This   review  should be   conducted   at  an
               appropriate time subsequent to implementation of changes,  as the
               Committee determines.

     D.    Process Improvement

           o   Establish regular and separate systems of  reporting to the Audit
               Committee by each of management, the independent auditors and the
               Director of Internal Auditing regarding any significant judgments
               made in management's preparation of  the financial statements and
               the view of each as to appropriateness of such judgments.

           o   Conduct  annual   evaluation  with   the   Board  regarding   the
               performance of the Audit Committee.

           o   Discuss with management and the Director  of Internal  Accounting
               policies with respect to risk assessment and risk management.

           o   Regularly  apprise   the  Board,   through  minutes  and  special
               presentations as  necessary,  of significant  developments in the
               course of performing these duties.

               submissions  by  employees  of  concerns  regarding  questionable
               accounting or auditing matters.

           o   Review any disclosures provided by the Chief Executive Officer or
               the  Chief  Financial  Officer  to the  Committee  regarding  (i)
               significant  deficiencies in  the design or operation of internal
               controls which  could adversely affect the  Company's  ability to
               record,  process,  summarize and  report financial data; and (ii)
               any fraud,  including that  which  involves  management or  other

               controls.

           o   Investigate at its discretion any matter brought to its attention
               by,   without  limitation,   reviewing  the  books,  records  and
               facilities of the  Company and interviewing  Company  officers or
               employees.

           o   Review  management's  monitoring  of  the   Company's  compliance
               programs and evaluate  whether management  has review  systems in

remain in its devoted employ.  A further purpose of this Plan is to provide such

designed to enhance the profitable growth of the Company. Accordingly, this Plan
primarily provides for the granting of Incentive Stock Options, options which do
not constitute  Incentive  Stock Options,  Restricted  Stock Awards,  Restricted
Stock Units, Stock Appreciation  Rights or any combination of the foregoing,  as
is best suited to the  circumstances  of the  particular  individual as provided

which  case  references  herein to the  "Committee"  shall be deemed to  include
references  to the "Board."  Subject to the express  provisions  of the Plan and
Rule 16b-3,  the Committee  shall have the  authority,  in its sole and absolute
discretion,  to (i) adopt,  amend, and rescind  administrative  and interpretive
rules and regulations  relating to the Plan; (ii) determine the Eligible Persons
to whom,  and the  time or  times at  which,  Awards  shall  be  granted;  (iii)

terms and  provisions  of each Award  agreement  (which need not be  identical),
including  provisions  defining  or  otherwise  relating to (A) the term and the

which the  transferability of shares of Stock issued or transferred  pursuant to
any Award is restricted,  (C) except as otherwise provided herein, the effect of
termination of employment of a Participant  on the Award,  and (D) the effect of
approved leaves of absence  (consistent  with any applicable  regulations of the
Internal  Revenue  Service);  (v) accelerate the time of  exercisability  of any
Award that has been granted;  (vi) construe the respective  Award agreements and
the  Plan;  (vii)  make  determinations  of the Fair  Market  Value of the Stock
pursuant to the Plan;  (viii)  delegate its duties under the Plan to such agents
as it may  appoint  from  time to  time,  provided  that the  Committee  may not
delegate its duties with respect to making Awards to, or otherwise  with respect
to Awards granted to,  Eligible  Persons who are subject to section 16(b) of the
Exchange Act or section 162(m) of the Code; (ix) terminate,  modify or amend the
Plan;  and (x) make all  other  determinations,  perform  all  other  acts,  and
exercise all other powers and authority necessary or advisable for administering
the   Plan,   including   the   delegation   of  those   ministerial   acts  and
responsibilities  as the Committee deems appropriate.  Subject to Rule 16b-3 and
section  162(m) of the Code,  the Committee  may correct any defect,  supply any

                                      -4-






omission,  or reconcile any  inconsistency  in the Plan, in any Award, or in any
Award  agreement in the manner and to the extent it deems necessary or desirable
to carry the Plan into  effect,  and the  Committee  shall be the sole and final
judge of that necessity or desirability.  The determinations of the Committee on
the matters referred to in this Section 3(a) shall be final and conclusive.

         (b)  Manner of  Exercise of  Committee  Authority.  At any  time that a
member of the Committee is not a Qualified  Member,  any action of the Committee
relating  to an Award  granted  or to be granted  to a  Participant  who is then
subject to section 16 of the Exchange Act in respect of the Company, or relating
to  an  Award  intended  by  the  Committee  to  qualify  as  "performance-based
compensation"  within the meaning of section 162(m) of the Code and  regulations
thereunder,  may be  taken  either  (i)  by a  subcommittee,  designated  by the
Committee,  composed  solely of two or more  Qualified  Members,  or (ii) by the
Committee but with each such member who is not a Qualified Member  abstaining or
recusing himself or herself from such action; provided, however, that, upon such
abstention or recusal,  the  Committee  remains  composed  solely of two or more
Qualified  Members.  Such action,  authorized by such a  subcommittee  or by the
Committee upon the abstention or recusal of such non-Qualified Member(s),  shall
be the action of the  Committee  for  purposes  of this Plan.  Any action of the
Committee shall be final,  conclusive and binding on all persons,  including the
Company,  its  Subsidiaries,  stockholders,  Participants,   Beneficiaries,  and
transferees  under Section 10(a) hereof or other persons claiming rights from or
through a Participant. The express grant of any specific power to the Committee,
and the  taking  of any  action by the  Committee,  shall  not be  construed  as
limiting any power or authority of the Committee.  The Committee may delegate to
officers or managers of the Company or any  Subsidiary,  or committees  thereof,
the  authority,  subject  to such terms as the  Committee  shall  determine,  to
perform such functions, including administrative functions, as the Committee may
determine,  to the extent that such delegation will not result in the loss of an
exemption under Rule  16b-3(d)(1) for Awards granted to Participants  subject to
section 16 of the  Exchange  Act in respect  of the  Company  and will not cause
Awards  intended to qualify as  "performance-based  compensation"  under section
162(m) of the Code to fail to so qualify.  The Committee  may appoint  agents to
assist it in administering this Plan.

         (c) Limitation of Liability.  The  Committee and  each  member  thereof
shall be  entitled  to,  in good  faith,  rely or act upon any  report  or other
information furnished to him or her by any officer or employee of the Company or
a Subsidiary, the Company's legal counsel, independent auditors,  consultants or
any other agents assisting in the  administration  of this Plan.  Members of the
Committee  and any officer or employee of the Company or a Subsidiary  acting at
the direction or on behalf of the Committee  shall not be personally  liable for
any action or  determination  taken or made in good  faith with  respect to this
Plan, and shall, to the fullest extent permitted by law, be indemnified and held
harmless by the Company with respect to any such action or determination.

     4.  Stock Subject to Plan.

         (a) Overall  Number  of  Shares  Available  for  Delivery.  Subject  to
adjustment in a manner  consistent  with any adjustment made pursuant to Section
9, the total number of shares of Stock  reserved and  available  for delivery in
connection with Awards under this Plan shall not exceed 4,600,000 shares and the
total  number  of  shares  of Stock  received  and  available  for  delivery  in
connection with ISOs under this Plan shall not exceed 4,600,000 shares. No Award
may be  granted  under  the  Plan on or  after  the 10 year  anniversary  of the
Effective Date.

         (b) Application of Limitation to  Grants of Awards.  No  Award  may  be
granted if the number of shares of Stock to be delivered in connection with such
Award exceeds the number of shares of Stock remaining  available under this Plan
minus the number of shares of Stock  issuable  in  settlement  of or relating to
then-outstanding  Awards. The Committee may adopt reasonable counting procedures
to ensure appropriate  counting,  avoid double counting (as, for example, in the
case of tandem or  substitute  awards)  and make  adjustments  if the  number of
shares of Stock actually  delivered differs from the number of shares previously
counted in connection with an Award.

         (c) Availability of  Shares Not  Issued under  Awards.  Shares of Stock
subject to an Award  under  this Plan that  expire or are  canceled,  forfeited,
settled in cash or  otherwise  terminated  without an  issuance of shares to the
Participant,  including  (i) the  number of shares  withheld  in  payment of any

                                      -5-






exercise or purchase price of an Award or taxes relating to Awards, and (ii) the
number of shares  surrendered in payment of any exercise or purchase price of an
Award or taxes  relating to any Award,  will again be available for Awards under
this Plan,  except  that if any such  shares  could not again be  available  for
Awards to a particular Participant under any applicable law or regulation,  such
shares shall be available  exclusively  for Awards to  Participants  who are not
subject to such limitation.

         (d) Stock Offered.  The shares to be  delivered under the Plan shall be
made available from (i) authorized but unissued shares of Stock, (ii) Stock held
in the  treasury of the  Company,  or (iii)  previously  issued  shares of Stock
reacquired by the Company, including shares purchased on the open market.

     5.  Eligibility; Per Person Award Limitations.  Awards may be granted under
this Plan only to Persons who are Eligible  Persons at the time of grant thereof
or in connection  with the severance or retirement of Eligible  Individuals.  In
each fiscal year or 12-month  period,  as  applicable,  during any part of which
this Plan is in effect,  a Covered Employee may not be granted (a) Awards (other
than Awards  designated  to be paid only in cash)  relating to more than 250,000
shares  of  Stock,  subject  to  adjustment  in a  manner  consistent  with  any
adjustment made pursuant to Section 9 and (b) Awards  designated to be paid only
in cash having a value determined on the date of grant in excess of $4,000,000.

     6.  Specific Terms of Awards.

forth in this Section 6. In addition,  the  Committee may impose on any Award or
the exercise  thereof,  at the date of grant or  thereafter  (subject to Section
10(c)),  such  additional  terms  and  conditions,  not  inconsistent  with  the
provisions of this Plan,  as the  Committee  shall  determine,  including  terms
requiring  forfeiture of Awards in the event of termination of employment by the
Participant and terms permitting a Participant to make elections relating to his
or  her  Award.  The  Committee  shall  retain  full  power  and  discretion  to
accelerate, waive or modify, at any time, any term or condition of an Award that
is not mandatory under this Plan;  provided,  however,  that the Committee shall
not have any discretion to accelerate,  waive or modify any term or condition of
an Award that is intended  to qualify as  "performance-based  compensation"  for
purposes of section 162(m) of the Code if such discretion  would cause the Award
to not so qualify.

         (b) Options.   The  Committee  is   authorized  to  grant   Options  to
Participants on the following terms and conditions:

             (i) Exercise Price.  Each Option agreement shall state the exercise
price per share of Stock (the "Exercise  Price");  provided,  however,  that the
Exercise  Price per share of Stock  subject to an ISO shall not be less than the
greater  of (A) the par  value  per  share of the  Stock or (B) 100% of the Fair
Market Value per share of the Stock as of the date of grant of the Option (or in
the case of an individual who owns stock  possessing more than 10 percent of the
total  combined  voting power of all classes of stock of the  Corporation or its
parent or any Subsidiary 110% of the Fair Market Value per share of the Stock on
the date of grant).  The exercise  price per share of Stock subject to an Option
other than an  Incentive  Stock Option shall not be less than the greater of (1)
the par value per share of the Stock and (2) 100% of the Fair  Market  Value per
share of the stock as of the date of grant of the Option.

             (ii) Time and Method of Exercise. The Committee shall determine the
time or times  at  which or the  circumstances  under  which  an  Option  may be
exercised in whole or in part  (including  based on  achievement  of performance
goals and/or future  service  requirements),  the methods by which such exercise
price  may be paid or  deemed to be paid,  the form of such  payment,  including
without limitation cash, Stock, other Awards or awards granted under other plans
of the Company or any Subsidiary,  or other property  (including  notes or other
contractual  obligations of Participants  to make payment on a deferred  basis),
and the  methods by or forms in which  Stock will be  delivered  or deemed to be
delivered  to  Participants,  including,  but not  limited  to, the  delivery of
Restricted Stock subject to Section 6(d). In the case of an exercise whereby the
Exercise Price is paid with Stock,  such Stock shall be valued as of the date of
exercise.


                                      -6-





             (iii) ISOs.  The terms  of any  ISO granted  under this  Plan shall
comply in all respects with the provisions of section 422 of the Code.  Anything
in this Plan to the contrary  notwithstanding,  no term of this Plan relating to
ISOs (including any SAR in tandem  therewith)  shall be interpreted,  amended or
altered,  nor shall any  discretion  or  authority  granted  under  this Plan be
exercised,  so as to disqualify either this Plan or any ISO under section 422 of
the Code, unless the Participant has first requested the change that will result
in such  disqualification.  ISOs shall not be granted  more than ten years after
the  earlier of the  adoption  of this Plan or the  approval of this Plan by the
Company's stockholders.  Notwithstanding the foregoing, the Fair Market Value of
shares of Stock subject to an ISO and the aggregate  Fair Market Value of shares
of stock of any parent or Subsidiary corporation (within the meaning of sections
424(e) and (f) of the Code) subject to any other  incentive stock option (within
the  meaning  of  section  422 of the  Code))  of the  Company  or a  parent  or
Subsidiary  corporation  (within the  meaning of sections  424(e) and (f) of the
Code) that first becomes  purchasable  by a Participant in any calendar year may
not (with respect to that Participant) exceed $100,000,  or such other amount as
may be prescribed  under section 422 of the Code or  applicable  regulations  or
rulings from time to time. As used in the previous  sentence,  Fair Market Value
shall be  determined  as of the date the  incentive  stock  options is  granted.
Failure to comply with this  provision  shall not impair the  enforceability  or
exercisability of any Option,  but shall cause the excess amount of shares to be
reclassified in accordance with the Code.

         (c) Stock Appreciation Rights.  The  Committee is  authorized  to grant
SARs to Participants on the following terms and conditions:

             (i) Right to Payment.  An SAR  shall  confer on the  Participant to
whom it is granted a right to receive,  upon exercise thereof, the excess of (A)
the Fair Market Value of one share of Stock on the date of exercise over (B) the
grant price of the SAR as determined by the Committee.

             (ii) Rights Related to Options.  A Stock Appreciation Right granted
pursuant to an Option shall entitle a Participant,  upon exercise,  to surrender
that Option or any portion thereof,  to the extent  unexercised,  and to receive
payment of an amount computed  pursuant to Subsection  6(c)(ii)(B).  That Option
shall then cease to be exercisable to the extent surrendered. Stock Appreciation
Rights granted in connection with an Option shall be subject to the terms of the
Award  agreement  governing  the Option,  which shall comply with the  following
provisions in addition to those applicable to Options:

                  (A) A Stock  Appreciation Right  granted in connection with an
         Option shall be exercisable only at such time or times and only  to the
         extent  that the  related  Option  is  exercisable  and  shall  not  be
         transferable  except   to  the   extent  that  the  related  Option  is
         transferable.

                  (B) Upon the exercise of a Stock Appreciation Right related to
         an Option, a Participant shall be  entitled to receive payment from the
         Company of an amount determined by multiplying:

                      (1) the difference  obtained by  subtracting  the exercise
              price of a share of Stock specified in the related Option from the
              Fair Market Value of a  share of Stock on  the date of exercise of
              the Stock Appreciation Right, by

                      (2)  the  number  of  shares  as   to  which   that  Stock
              Appreciation Right has been exercised.

             (iii) Right Without  Option.  A Stock  Appreciation  Right  granted
independent of an Option shall be exercisable as determined by the Committee and
set forth in the Award agreement  governing the Stock Appreciation  Right, which
Award agreement shall comply with the following provisions:

                  (A) Each  Award  agreement  shall  state  the total  number of
         shares of Stock to which the Stock Appreciation Right relates.


                                      -7-





                  (B) Each Award agreement  shall state  the time  or periods in
         which the right to exercise  the Stock Appreciation  Right or a portion
         thereof shall  vest and the  number of shares  of Stock  for which  the
         right to exercise the Stock Appreciation Right shall  vest at each such
         time or period.

                  (C) Each  Award  agreement shall  state the  date at which the
         Stock Appreciation Rights shall expire if not previously exercised.

                  (D) Each Stock Appreciation Right shall entitle a participant,
         upon exercise thereof, to receive payment of an amount determined by
         multiplying:

                      (1) the difference obtained by subtracting the Fair Market
              Value  of a  share of  Stock on  the date  of grant  of the  Stock
              Appreciation Right from the Fair Market  Value of a share of Stock
              on the date of  exercise  of that Stock Appreciation Right, by

                      (2)  the  number  of   shares  as  to   which  the   Stock
              Appreciation Right has been exercised.

             (iv) Terms.  Except as  otherwise  provided  herein,  the Committee
shall  determine at the date of grant or thereafter,  the time or times at which
and the  circumstances  under which an SAR may be  exercised in whole or in part
(including  based on  achievement  of  performance  goals and/or future  service
requirements),   the  method  of  exercise,   method  of  settlement,   form  of
consideration  payable in settlement,  method by or forms in which Stock will be
delivered or deemed to be delivered to Participants, whether or not an SAR shall
be in tandem or in  combination  with any other  Award,  and any other terms and
conditions of any SAR. SARs may be either  freestanding  or in tandem with other
Awards.

         (d) Restricted Stock.  The Committee is  authorized to grant Restricted
Stock to Participants on the following terms and conditions:

             (i) Grant and  Restrictions.  Restricted Stock shall  be subject to
such restrictions on transferability, risk of forfeiture and other restrictions,
if any, as the Committee may impose,  which restrictions may lapse separately or
in  combination  at such times,  under such  circumstances  (including  based on
achievement of performance  goals and/or future service  requirements),  in such
installments  or otherwise,  as the Committee may determine at the date of grant
or thereafter.  During the restricted period applicable to the Restricted Stock,
the  Restricted  Stock  may not be  sold,  transferred,  pledged,  hypothecated,
margined or otherwise encumbered by the Participant.

             (ii) Certificates for  Stock.  Restricted Stock granted  under this
Plan may be  evidenced  in such  manner as the  Committee  shall  determine.  If
certificates  representing  Restricted  Stock are  registered in the name of the
Participant,   the  Committee  may  require  that  such   certificates  bear  an
appropriate   legend  referring  to  the  terms,   conditions  and  restrictions
applicable to such Restricted Stock, that the Company retain physical possession
of the  certificates,  and that the  Participant  deliver  a stock  power to the
Company, endorsed in blank, relating to the Restricted Stock.

             (iii) Dividends and Splits. As a condition to the grant of an Award
of Restricted  Stock, the Committee may require or permit a Participant to elect
that any cash  dividends  paid on a share of Restricted  Stock be  automatically
reinvested in additional  shares of Restricted  Stock or applied to the purchase
of  additional  Awards  under  this Plan.  Unless  otherwise  determined  by the
Committee, Stock distributed in connection with a Stock split or Stock dividend,
and other property  distributed as a dividend,  shall be subject to restrictions
and a risk of forfeiture to the same extent as the Restricted Stock with respect
to which such Stock or other property has been distributed.

         (e) Restricted  Stock  Units.  The  Committee  is  authorized  to grant
Restricted Stock Units to Participants, which are rights to receive Stock at the
end  of a  specified  deferral  period,  subject  to  the  following  terms  and
conditions:


                                      -8-






             (i) Award and Restrictions.  Settlement of  an Award  of Restricted
Stock Units shall occur upon  expiration  of the deferral  period  specified for
such Restricted  Stock Unit by the Committee (or, if permitted by the Committee,
as elected by the  Participant).  In addition,  Restricted  Stock Units shall be
subject to such  restrictions  (which may include a risk of  forfeiture)  as the
Committee may impose, if any, which  restrictions may lapse at the expiration of
the  deferral  period  or  at  earlier   specified  times  (including  based  on
achievement of performance goals and/or future service requirements), separately
or in combination, in installments or otherwise, as the Committee may determine.
Restricted  Stock Units shall be  satisfied  by the delivery of cash or Stock in
the amount equal to the Fair Market Value of the  specified  number of shares of
Stock  covered by the  Restricted  Stock Units,  or a  combination  thereof,  as
determined by the Committee at the date of grant or thereafter.

             (ii) Dividend  Equivalents.  Unless  otherwise  determined  by  the
Committee at date of grant,  Dividend  Equivalents  on the  specified  number of
shares of Stock  covered by an Award of  Restricted  Stock Units shall be either
(A) paid with respect to such  Restricted  Stock Units on the  dividend  payment
date in cash or in shares of unrestricted Stock having a Fair Market Value equal
to the amount of such dividends, or (B) deferred with respect to such Restricted
Stock Units and the amount or value thereof  automatically  deemed reinvested in
additional Restricted Stock Units, other Awards or other investment vehicles, as
the Committee shall determine or permit the Participant to elect.

         (f) Bonus Stock and  Awards in  Lieu of  Obligations.  The Committee is
authorized to grant Stock as a bonus,  or to grant Stock or other Awards in lieu
of  obligations  to pay cash or deliver other  property under this Plan or under
other  plans  or  compensatory  arrangements,  provided  that,  in the  case  of
Participants  subject  to  section 16 of the  Exchange  Act,  the amount of such
grants remains within the discretion of the Committee to the extent necessary to
ensure that  acquisitions  of Stock or other  Awards are exempt  from  liability
under section 16(b) of the Exchange Act. Stock or Awards granted hereunder shall
be subject to such other terms as shall be determined by the  Committee.  In the
case of any grant of Stock to an officer of the Company or a Subsidiary  in lieu
of salary or other cash  compensation,  the number of shares granted in place of
such compensation shall be reasonable, as determined by the Committee.

         (g) Dividend Equivalents. The Committee is authorized to grant Dividend
Equivalents to a Participant,  entitling the Participant to receive cash, Stock,
other Awards, or other property equal in value to dividends paid with respect to
a specified  number of shares of Stock,  or other  periodic  payments.  Dividend
Equivalents  may be  awarded  on a  free-standing  basis or in  connection  with
another Award. The Committee may provide that Dividend Equivalents shall be paid
or  distributed  when  accrued  or shall be deemed to have  been  reinvested  in
additional  Stock,  Awards,  or other investment  vehicles,  and subject to such
restrictions on  transferability  and risks of forfeiture,  as the Committee may
specify.

         (h) Other Stock-Based Awards.  The Committee is authorized,  subject to
limitations  under  applicable law, to grant to  Participants  such other Awards
that may be  denominated  or payable in, valued in whole or in part by reference
to, or otherwise  based on, or related to, Stock,  as deemed by the Committee to
be  consistent  with the  purposes of this Plan,  including  without  limitation
convertible  or  exchangeable  debt  securities,  other  rights  convertible  or
exchangeable  into  Stock,  purchase  rights  for Stock,  Awards  with value and
payment  contingent  upon  performance  of  the  Company  or any  other  factors
designated by the Committee, and Awards valued by reference to the book value of
Stock  or  the  value  of  securities  of  or  the   performance   of  specified
Subsidiaries.  The Committee  shall  determine the terms and  conditions of such
Awards.  Stock delivered  pursuant to an Award in the nature of a purchase right
granted under this Section 6(h) shall be purchased for such consideration,  paid
for at such  times,  by such  methods,  and in such  forms,  including,  without
limitation, cash, Stock, other Awards, or other property, as the Committee shall
determine.  Cash awards, as an element of or supplement to any other Award under
this Plan, may also be granted pursuant to this Section 6(h).

     7.  Certain Provisions Applicable to Awards.

         (a) Termination of Employment. Except as provided herein, the treatment
of an Award upon a termination  of employment or any other service  relationship
by and between a Participant and any Company or Subsidiary shall be specified in
the agreement controlling such Award.



                                      -9-





         (b) Stand-Alone,  Additional,  Tandem,  and  Substitute  Awards. Awards
granted  under this Plan may, in the  discretion  of the  Committee,  be granted
either alone or in addition to, in tandem with, or in  substitution  or exchange
for, any other Award or any award granted under another plan of the Company, any
Subsidiary,  or  any  business  entity  to  be  acquired  by  the  Company  or a
Subsidiary,  or any other right of a  Participant  to receive  payment  from the
Company or any Subsidiary.  Such  additional,  tandem and substitute or exchange
Awards  may be granted at any time.  If an Award is granted in  substitution  or
exchange for another  Award,  the Committee  shall require the surrender of such
other Award in consideration for the grant of the new Award. In addition, Awards
may be granted in lieu of cash  compensation,  including in lieu of cash amounts
payable under other plans of the Company or any  Subsidiary,  in which the value
of Stock subject to the Award is  equivalent  in value to the cash  compensation
(for  example,  Restricted  Stock Units or  Restricted  Stock),  or in which the
exercise  price,  grant price or purchase  price of the Award in the nature of a
right that may be exercised is equal to the Fair Market Value of the  underlying
Stock minus the value of the cash compensation surrendered (for example, Options
granted  with  an  exercise  price  "discounted"  by  the  amount  of  the  cash
compensation surrendered).

         (c) Term of Awards.  The term of each Award shall be for such period as
may be determined by the Committee;  provided that in no event shall the term of
any Option or SAR exceed a period of ten years (or such  shorter  term as may be
required in respect of an ISO under section 422 of the Code).

         (d) Form and Timing of Payment under Awards; Deferrals.  Subject to the
terms of this Plan and any applicable  Award  agreement,  payments to be made by
the  Company or a  Subsidiary  upon the  exercise of an Option or other Award or
settlement  of an  Award  may be made  in  such  forms  as the  Committee  shall
determine,  including  without  limitation  cash,  Stock,  other Awards or other
property,  and may be made in a single payment or transfer, in installments,  or
on a deferred basis.  Except as otherwise provided herein, the settlement of any
Award may be accelerated, and cash paid in lieu of Stock in connection with such
settlement, in the discretion of the Committee or upon occurrence of one or more
specified  events (in addition to a Change in Control).  Installment or deferred
payments  may be required  by the  Committee  (subject to Section  10(c) of this
Plan, including the consent provisions thereof in the case of any deferral of an
outstanding Award not provided for in the original Award agreement) or permitted
at the election of the  Participant on terms and  conditions  established by the
Committee. Payments may include, without limitation,  provisions for the payment
or crediting of reasonable  interest on installment or deferred  payments or the
grant or  crediting  of  Dividend  Equivalents  or other  amounts  in respect of
installment or deferred  payments  denominated in Stock. Any deferral shall only
be allowed as is provided in a separate  deferred  compensation  plan adopted by
the  Company.  This Plan shall not  constitute  an "employee  benefit  plan" for
purposes of section 3(3) of the Employee Retirement Income Security Act of 1974,
as amended.

         (e) Exemptions from Section 16(b)  Liability.  It is the  intent of the
Company that the grant of any Awards to or other  transaction  by a  Participant
who is  subject  to section  16 of the  Exchange  Act shall be exempt  from such
section   pursuant  to  an  applicable   exemption   (except  for   transactions
acknowledged in writing to be non-exempt by such Participant).  Accordingly,  if
any  provision  of this Plan or any Award  agreement  does not  comply  with the
requirements  of Rule 16b-3 as then  applicable  to any such  transaction,  such
provision  shall be  construed  or deemed  amended  to the extent  necessary  to
conform to the applicable  requirements  of Rule 16b-3 so that such  Participant
shall avoid liability under section 16(b) of the Exchange Act.

         (f) Non-Competition Agreement.  Each  Participant to  whom an  Award is
granted  under this Plan may be required  to agree in writing as a condition  to
the  granting  of such Award not to engage in conduct  in  competition  with the
Company or any of its  Subsidiaries  for a period after the  termination of such
Participant's  employment with the Company and its Subsidiaries as determined by
the Committee.

     8.  Performance and Annual Incentive Awards.

         (a) Performance Conditions.  The right of a  Participant to exercise or
receive a grant or  settlement  of any  Award,  and the timing  thereof,  may be
subject to such performance conditions as may be specified by the Committee. The
Committee may use such business criteria and other measures of performance as it
may  deem  appropriate  in  establishing  any  performance  conditions,  and may

                                      -10-






exercise  its  discretion  to reduce or increase the amounts  payable  under any
Award subject to performance  conditions,  except as limited under Sections 8(b)
and 8(c) hereof in the case of a  Performance  Award or Annual  Incentive  Award
intended to qualify under section 162(m) of the Code.

         (b) Performance Awards Granted to Designated Covered Employees.  If the
Committee  determines  that a  Performance  Award to be granted  to an  Eligible
Person who is  designated  by the  Committee as likely to be a Covered  Employee
should  qualify as  "performance-based  compensation"  for  purposes  of section
162(m) of the Code, the grant,  exercise and/or  settlement of such  Performance
Award may be contingent upon achievement of preestablished performance goals and
other terms set forth in this Section 8(b).

             (i) Performance Goals Generally.  The  performance  goals  for such
Performance  Awards shall consist of one or more business criteria or individual
performance  criteria and a targeted level or levels of performance with respect
to each of such  criteria,  as specified by the Committee  consistent  with this
Section 8(b).  Performance goals shall be objective and shall otherwise meet the
requirements of section 162(m) of the Code and regulations thereunder (including
Treasury Regulation  ss.1.162-27 and successor regulations  thereto),  including
the  requirement  that the  level  or  levels  of  performance  targeted  by the
Committee  result in the achievement of performance  goals being  "substantially
uncertain."  The Committee may determine that such  Performance  Awards shall be
granted,  exercised, and/or settled upon achievement of any one performance goal
or that two or more of the performance  goals must be achieved as a condition to
grant, exercise and/or settlement of such Performance Awards.  Performance goals
may differ for Performance Awards granted to any one Participant or to different
Participants.

             (ii) Business and Individual Performance Criteria

                  (A) Business Criteria.  One or more of the  following business
criteria  for  the  Company,  on a  consolidated  basis,  and/or  for  specified
Subsidiaries  or business or  geographical  units of the  Company  (except  with
respect to the total stockholder return and earnings per share criteria),  shall
be used by the Committee in establishing  performance goals for such Performance
Awards:  (1) earnings per share; (2) increase in revenues;  (3) increase in cash
flow; (4) increase in cash flow return;  (5) return on net assets; (6) return on
assets,  return on investment;  (7) return on capital; (8) return on equity; (9)
economic value added; (10) operating margin; (11) contribution  margin; (12) net
income;   (13)  pretax   earnings;   (14)  pretax  earnings   before   interest,
depreciation,  amortization,  exploration  and  abandonment  costs;  (15) pretax
operating earnings after interest expense and before  incentives,  service fees,
and extraordinary or special items; or operating income;  (16) total stockholder
return;   (17)  debt  reduction;   (18)  production  growth;  (19)  general  and
administrative expenses; (20) reserve replacement;  (21) finding and development
costs;  (22) net asset value;  (23) operating  costs,  and (24) any of the above
goals  determined  on an  absolute  or  relative  basis  or as  compared  to the
performance  of a published or special index deemed  applicable by the Committee
including,  but not limited to, the Standard & Poor's 500 Stock Index or a group
of comparable  companies.  One or more of the foregoing  business criteria shall
also be exclusively used in establishing  performance goals for Annual Incentive
Awards granted to a Covered Employee under Section 8(c) hereof.

                  (B) Individual  Performance  Criteria.  The  grant,   exercise
and/or  settlement of Performance  Awards may also be contingent upon individual
performance goals established by the Committee.  If required for compliance with
section 162(m) of the Code, such criteria shall be approved by the  stockholders
of the Company.

             (iii) Performance  Period;   Timing  for  Establishing  Performance
Goals.  Achievement of performance  goals in respect of such Performance  Awards
shall be measured over a performance  period of up to ten years, as specified by
the Committee.  Performance  goals shall be  established  not later than 90 days
after the beginning of any  performance  period  applicable to such  Performance
Awards,   or  at  such  other  date  as  may  be  required  or   permitted   for
"performance-based compensation" under section 162(m) of the Code.

             (iv) Performance  Award  Pool.   The  Committee   may  establish  a
Performance  Award  pool,  which  shall be an  unfunded  pool,  for  purposes of
measuring  performance of the Company in connection with Performance Awards. The

                                      -11-





amount of such  Performance  Award pool shall be based upon the achievement of a
performance  goal or goals  based on one or more of the  criteria  set  forth in
Section 8(b)(ii) hereof during the given performance period, as specified by the
Committee in accordance with Section 8(b)(iii) hereof. The Committee may specify
the  amount  of the  Performance  Award  pool  as a  percentage  of any of  such
criteria,  a percentage  thereof in excess of a threshold  amount, or as another
amount  which  need  not  bear a  strictly  mathematical  relationship  to  such
criteria.

             (v) Settlement of Performance Awards; Other Terms. After the end of
each performance  period,  the Committee shall determine the amount,  if any, of
(A) the Performance Award pool, and the maximum amount of potential  Performance
Award  payable to each  Participant  in the  Performance  Award pool, or (B) the
amount of potential  Performance  Award otherwise  payable to each  Participant.
Settlement of such Performance  Awards shall be in cash, Stock,  other Awards or
other  property,  in the discretion of the Committee.  The Committee may, in its
discretion, reduce the amount of a settlement otherwise to be made in connection
with such Performance  Awards,  but may not exercise  discretion to increase any
such  amount  payable to a Covered  Employee in respect of a  Performance  Award
subject to this Section 8(b). The Committee shall specify the  circumstances  in
which  such  Performance  Awards  shall  be paid or  forfeited  in the  event of
termination of employment by the  Participant  prior to the end of a performance
period or settlement of Performance Awards.

         (c) Annual Incentive Awards Granted to Designated Covered Employees. If
the  Committee  determines  that an Annual  Incentive  Award to be granted to an
Eligible  Person who is  designated  by the  Committee as likely to be a Covered
Employee  should  qualify as  "performance-based  compensation"  for purposes of
section 162(m) of the Code, the grant, exercise and/or settlement of such Annual
Incentive  Award  shall  be  contingent  upon   achievement  of   preestablished
performance goals and other terms set forth in this Section 8(c).

             (i) Annual Incentive Award Pool.  The  Committee  may  establish an
Annual  Incentive  Award pool,  which shall be an unfunded pool, for purposes of
measuring performance of the Company in connection with Annual Incentive Awards.
The  amount  of such  Annual  Incentive  Award  pool  shall  be  based  upon the
achievement of a performance  goal or goals based on one or more of the business
criteria  set forth in Section  8(b)(ii)  hereof  during  the given  performance
period,  as specified  by the  Committee in  accordance  with Section  8(b)(iii)
hereof.  The Committee may specify the amount of the Annual Incentive Award pool
as a percentage of any of such business criteria, a percentage thereof in excess
of a  threshold  amount,  or as  another  amount  which need not bear a strictly
mathematical relationship to such business criteria.

             (ii) Potential Annual Incentive Awards.  Not later than  the end of
the 90th day of each  applicable  year, or at such other date as may be required
or  permitted  in  the  case  of  Awards   intended  to  be   "performance-based
compensation"  under section 162(m) of the Code, the Committee  shall  determine
the Eligible Persons who will potentially  receive Annual Incentive Awards,  and
the amounts potentially payable thereunder,  for that fiscal year, either out of
an Annual  Incentive  Award pool  established by such date under Section 8(c)(i)
hereof or as  individual  Annual  Incentive  Awards.  In the case of  individual
Annual  Incentive  Awards  intended to qualify under section 162(m) of the Code,
the  amount  potentially  payable  shall be  based  upon  the  achievement  of a
performance  goal or goals  based on one or more of the  business  criteria  set
forth in Section 8(b)(ii) hereof in the given  performance year, as specified by
the Committee;  in situations  not governed by section 162(m) of the Code,  such
amount shall be based on such criteria as shall be established by the Committee.
In all cases,  the maximum Annual  Incentive Award of any  Participant  shall be
subject to the limitation set forth in Section 5 hereof.

             (iii) Payout of Annual  Incentive  Awards.  After the  end of  each
applicable  year, the Committee shall  determine the amount,  if any, of (A) the
Annual  Incentive  Award  pool,  and the  maximum  amount  of  potential  Annual
Incentive Award payable to each  Participant in the Annual Incentive Award pool,
or (B) the amount of potential Annual Incentive Award otherwise  payable to each
Participant.  The Committee  may, in its  discretion,  determine that the amount
payable to any Participant as a final Annual  Incentive Award shall be increased
or  reduced  from the amount of his or her  potential  Annual  Incentive  Award,
including  a  determination  to  make no  final  Award  whatsoever,  but may not

                                      -12-





exercise  discretion  to  increase  any such  amount  in the  case of an  Annual
Incentive  Award  intended  to qualify  under  section  162(m) of the Code.  The
Committee  shall specify the  circumstances  in which an Annual  Incentive Award
shall be paid or  forfeited in the event of  termination  of  employment  by the
Participant prior to the end of the applicable year or settlement of such Annual
Incentive Award.

         (d) Written Determinations.  All determinations by the  Committee as to
the establishment of performance goals, the amount of any Performance Award pool
or  potential  individual  Performance  Awards  and  as to  the  achievement  of
performance  goals  relating to  Performance  Awards under Section 8(b), and the
amount  of any  Annual  Incentive  Award  pool or  potential  individual  Annual
Incentive  Awards and the amount of final Annual  Incentive Awards under Section
8(c),  shall be made in  writing  in the case of any Award  intended  to qualify
under  section   162(m)  of  the  Code.  The  Committee  may  not  delegate  any
responsibility relating to such Performance Awards or Annual Incentive Awards.

         (e) Status of Section 8(b) and Section 8(c) Awards under Section 162(m)
of the Code. It is the intent of the Company that Performance  Awards and Annual
Incentive  Awards under Sections 8(b) and 8(c) hereof granted to persons who are
designated by the Committee as likely to be Covered Employees within the meaning
of section 162(m) of the Code and  regulations  thereunder  (including  Treasury
Regulation   ss.1.162-27  and  successor   regulations  thereto)  shall,  if  so
designated by the Committee, constitute "performance-based  compensation" within
the  meaning  of  section  162(m)  of  the  Code  and  regulations   thereunder.
Accordingly,  the  terms of  Sections  8(b),  (c),  (d) and (e),  including  the
definitions  of  Covered  Employee  and  other  terms  used  therein,  shall  be
interpreted  in a  manner  consistent  with  section  162(m)  of  the  Code  and
regulations  thereunder.  The foregoing  notwithstanding,  because the Committee
cannot  determine with certainty  whether a given  Participant will be a Covered
Employee with respect to a fiscal year that has not yet been completed, the term
Covered  Employee  as used  herein  shall mean only a person  designated  by the
Committee,  at the time of grant of  Performance  Awards or an Annual  Incentive
Award,  who is likely to be a Covered Employee with respect to that fiscal year.
If any  provision  of this  Plan as in  effect  on the date of  adoption  or any
agreements  relating to Performance  Awards or Annual  Incentive Awards that are
designated as intended to comply with section 162(m) of the Code does not comply
or is  inconsistent  with the  requirements  of  section  162(m)  of the Code or
regulations  thereunder,  such provision shall be construed or deemed amended to
the extent necessary to conform to such requirements.

     9.  Recapitalization or Reorganization; Change in Control.

         (a) Existence of Plans and Awards.  The existence of this  Plan and the
Awards granted  hereunder  shall not affect in any way the right or power of the
Board or the  stockholders  of the Company to make or authorize any  adjustment,
recapitalization,  reorganization  or  other  change  in the  Company's  capital
structure or its business, any merger or consolidation of the Company, any issue
of debt or equity  securities ahead of or affecting Stock or the rights thereof,
the  dissolution or liquidation of the Company or any sale,  lease,  exchange or
other  disposition  of all or any part of its  assets or  business  or any other
corporate act or proceeding.

         (b) Subdivision or Consolidation of Shares.  The terms of  an Award and
the number of shares of Stock  authorized  pursuant  to  Section 4 for  issuance
under the Plan shall be subject to  adjustment  from time to time, in accordance
with the following provisions:

             (i) If at  any  time,  or from  time to  time,  the  Company  shall
subdivide as a whole (by reclassification,  by a Stock split, by the issuance of
a distribution  on Stock payable in Stock, or otherwise) the number of shares of
Stock then  outstanding  into a greater number of shares of Stock,  then (A) the
maximum number of shares of Stock  available for the Plan as provided in Section
4 shall be increased proportionately, and the kind of shares or other securities
available for the Plan shall be appropriately adjusted, (B) the number of shares
of Stock (or other kind of shares or securities)  that may be acquired under any
Award  shall be  increased  proportionately,  and (C) the price  (including  the
exercise  price) for each share of Stock (or other kind of shares or securities)
subject to then  outstanding  Awards shall be reduced  proportionately,  without
changing the aggregate  purchase price or value as to which  outstanding  Awards
remain exercisable or subject to restrictions.



                                      -13-





             (ii) If at  any time,  or from  time  to time,  the  Company  shall
consolidate as a whole (by reclassification,  reverse Stock split, or otherwise)
the number of shares of Stock then outstanding into a lesser number of shares of
Stock,  (A) the  maximum  number of shares  of Stock  available  for the Plan as
provided in Section 4 shall be decreased proportionately, and the kind of shares
or other securities available for the Plan shall be appropriately  adjusted, (B)
the number of shares of Stock (or other kind of shares or  securities)  that may
be acquired  under any Award  shall be  decreased  proportionately,  and (C) the
price  (including the exercise  price) for each share of Stock (or other kind of
shares or  securities)  subject to then  outstanding  Awards  shall be increased
proportionately,  without  changing the aggregate  purchase price or value as to
which outstanding Awards remain exercisable or subject to restrictions.

             (iii) Whenever the number of shares of Stock subject to outstanding
Awards and the price for each share of Stock subject to  outstanding  Awards are
required to be adjusted as provided in this Section 9(b),  the  Committee  shall
promptly  prepare  a notice  setting  forth,  in  reasonable  detail,  the event
requiring  adjustment,  the amount of the  adjustment,  the method by which such
adjustment was  calculated,  and the change in price and the number of shares of
Stock,  other securities,  cash, or property  purchasable  subject to each Award
after giving effect to the  adjustments.  The Committee shall promptly give each
Participant such a notice.

             (iv) Adjustments under  Subsections 9(b)(i) and (ii)  shall be made
by the Committee, and its determination as to what adjustments shall be made and
the extent  thereof  shall be final,  binding,  and  conclusive.  No  fractional
interest shall be issued under the Plan on account of any such adjustments.

         (c)  Corporate Recapitalization.

             (i) If the Company  recapitalizes,  reclassifies its capital stock,
or otherwise  changes its capital structure (a  "recapitalization"),  the number
and class of shares of Stock covered by an Option or an SAR theretofore  granted
shall be adjusted so that such Option or SAR shall  thereafter  cover the number
and class of shares of stock and  securities to which the holder would have been
entitled pursuant to the terms of the  recapitalization if, immediately prior to
the recapitalization,  the holder had been the holder of record of the number of
shares of Stock  then  covered by such  Option or SAR and the share  limitations
provided in Sections 4 and 5 shall be adjusted in a manner  consistent  with the
recapitalization.

             (ii) In the event of changes  in the outstanding Stock by reason of
recapitalization,   reorganizations,   mergers,  consolidations,   combinations,
exchanges or other relevant changes in  capitalization  occurring after the date
of the grant of any Award and not otherwise  provided for by this Section 9, any
outstanding Awards and any agreements evidencing such Awards shall be subject to
adjustment  by the  Committee  at its  discretion  as to the number and price of
shares of Stock or other  consideration  subject to such Awards. In the event of
any such  change  in the  outstanding  Stock,  the  aggregate  number  of shares
available under this Plan may be appropriately adjusted by the Committee,  whose
determination shall be conclusive.

         (d) Additional Issuances.  Except as  hereinbefore  expressly provided,
the  issuance  by the  Company  of shares  of stock of any  class or  securities
convertible  into  shares of stock of any class,  for cash,  property,  labor or
services, upon direct sale, upon the exercise of rights or warrants to subscribe
therefor, or upon conversion of shares or obligations of the Company convertible
into such shares or other  securities,  and in any case  whether or not for fair
value,  shall not affect, and no adjustment by reason thereof shall be made with
respect to, the number of shares of Stock subject to Awards theretofore  granted
or the purchase price per share, if applicable.

         (e) Change in Control. Upon the occurrence of a Change in Control, with
respect only to Awards held by  Participants  who are  employees or directors of
the Company (and their permitted  transferees  pursuant to Section 10(a)) at the
occurrence  of the Change in Control,  (i) all  outstanding  Stock  Appreciation
Rights and Options  shall  immediately  become fully vested and  exercisable  in
full,  including  that  portion of any Stock  Appreciation  Right or Option that
pursuant to the terms and provisions of the applicable  Award  Agreement had not
yet become  exercisable (the total number of shares of Stock as to which a Stock


                                      -14-





Appreciation  Right or Option is exercisable  upon the occurrence of a Change in
Control is  referred  to herein as the  "Total  Shares");  (ii) the  restriction
period of any Restricted Stock Award and Restricted Stock Unit shall immediately
be accelerated  and the  restrictions  shall expire;  and (iii) the  performance
goals established  under the Performance  Awards will be deemed to have been met
for all  performance  periods upon the occurrence of a Change in Control and the
holder will be paid a pro rata portion of all  associated  targeted  performance
goals (based on the number of complete and partial calendar months elapsed as of
the  occurrence of the Change in Control) in cash within  thirty days  following
the Change in Control or in Stock  effective  as of the Change in  Control,  for
cash and stock-based  Performance  Awards  respectively.  If a Change in Control
involves  a  Restructure  or  occurs  in  connection  with a series  of  related
transactions involving a Restructure and if such Restructure is in the form of a
Non-Surviving  Event and as a part of such  Restructure  shares of stock,  other
securities,  cash or property  shall be issuable or  deliverable in exchange for
Stock,  then the holder of an Award shall be entitled to purchase or receive (in
lieu of the Total Shares that the holder would otherwise be entitled to purchase
or  receive),  as  appropriate  for the form of Award,  the  number of shares of
stock,  other securities,  cash or property to which that number of Total Shares
would have been entitled in connection with such Restructure  (and, for Options,
at an aggregate  exercise price equal to the Exercise Price that would have been
payable if that number of Total Shares had been purchased on the exercise of the
Option immediately before the consummation of the Restructure).

         (f) Restructure and No Change in Control.  In the  event a  Restructure
should occur at any time while there is any outstanding  Option, SAR, Restricted
Stock Award or Restricted  Stock Unit  hereunder and that  Restructure  does not
occur in connection  with a Change in Control or in connection  with a series of
related transactions involving a Change in Control, then:

             (i)  no  holder  of   an  Option  shall  automatically  be  granted
corresponding SARs;

             (ii) neither any outstanding SARs nor any outstanding Options shall
immediately  become fully vested and  exercisable  in full merely because of the
occurrence of the Restructure;

             (iii) the  restriction  period  of any  Restricted  Stock  Award or
Restricted  Stock Unit shall not immediately be accelerated and the restrictions
shall not expire merely because of the occurrence of the Restructure; and

             (iv) at the option of the Committee, the Company may (but shall not
be required to) take any one or more of the following actions:

                  (A) grant each holder of an Option corresponding Stock or cash
         SARs;

                  (B) accelerate in whole or in part the time of the vesting and
         exercisability  of any one or  more of the outstanding SARs and Options
         so as to provide  that  those SARs  and Options  shall  be  exercisable
         before, upon, or after the consummation of the Restructure;

                  (C) accelerate in  whole or in part the  expiration of some or
         all of the restrictions  on any Restricted  Stock Award  or  Restricted
         Stock Unit so that the Stock subject to  that Restricted Stock Award or
         Restricted Stock Unit shall be  owned by the holder without restriction
         or risk of forfeiture;

                  (D) the performance  goals  established  under the Performance
         Awards will not be deemed  to have been fully  met for all  performance
         periods merely because of the occurrence of the Restructure;

                  (E) if the  Restructure  is in  the  form  of a  Non-Surviving
         Event, cause the surviving entity to assume in whole or in part any one
         or more of the  outstanding Options, SARs,  Restricted Stock Awards and
         Restricted Stock Units upon such terms and provisions  as the Committee
         deems desirable; or



                                      -15-





                  (F) redeem  in  whole  or in  part  any  one  or  more  of the
         outstanding Options, SARs, Restricted Stock Awards and Restricted Stock
         Units  (whether or  not then  exercisable)  in consideration  of a cash
         payment, as such payment may be reduced for tax withholding obligations
         as contemplated in the section  governing the particular form of Award,
         in an amount equal to:

                      (1) for  Options  and  SARs  granted  in  connection  with
              Options, the excess of a) the  Fair Market Value, determined as of
              the   date   immediately   preceding  the   consummation  of   the
              Restructure, of the aggregate number of shares of Stock subject to
              the Award and as to which  the Award is being redeemed over b) the
              Exercise Price for that number of shares of Stock;

                      (2) for SARs not granted in connection with an Option, the
              excess of (a)  the Fair  Market Value,  determined as of  the date
              immediately preceding the consummation of the Restructure,  of the
              aggregate number of shares of Stock subject to the Award and as to
              which the Award is being redeemed  over (b) the  Fair Market Value
              of the number of shares of Stock on the date of grant;

                      (3) for  Restricted  Stock  Awards  and  Restricted  Stock
              Units,   the  Fair  Market  Value,   determined  as  of  the  date
              immediately preceding the consummation of the  Restructure, of the
              aggregate number of shares of Stock subject to the Award and as to
              which the Award is being redeemed; and

                      (4) for  Performance  Awards,  the amount  per Performance
              Award as the Committee in its sole discretion may determine (which
              may be zero dollars).

The Company shall  promptly  notify each holder of an outstanding  Option,  SAR,
Restricted  Stock Award or Restricted Stock Unit of any election or action taken
by the Company  under this Section  9(f). In the event of any election or action
taken by the Company  pursuant to this Section 9(f) that  requires the amendment
or  cancellation of any Award agreement as may be specified in any notice to the
holder thereof,  that holder shall promptly  deliver that Award agreement to the
Company in order for that  amendment or  cancellation  to be  implemented by the
Company and the  Committee.  The failure of the holder to deliver any such Award
agreement to the Company as provided in the preceding  sentence shall not in any
manner effect the validity or  enforceability of any action taken by the Company
and the Committee under this Section 9(f),  including,  without limitation,  any
redemption of an Option, SAR, Restricted Stock Award or Restricted Stock Unit as
of the consummation of a Restructure. Any cash payment to be made by the Company
pursuant  to  this  Section  9(f)  in  connection  with  the  redemption  of any
outstanding  Options,  SARs,  Restricted  Stock Awards or Restricted Stock Units
shall be paid to the holder  thereof  currently with the delivery to the Company
of the Award agreement evidencing that Award;  provided,  however, that any such
redemption   shall  be  effective  upon  the  consummation  of  the  Restructure
notwithstanding that the payment of the redemption price may occur subsequent to
the  consummation.  If  all  or  any  portion  of an  outstanding  Option,  SAR,
Restricted  Stock  Award  or  Restricted  Stock  Unit  is  to  be  exercised  or
accelerated  upon or after the consummation of a Restructure that is in the form
of a  Non-Surviving  Event  and as a part of that  Restructure  shares of stock,
other securities,  cash or property shall be issuable or deliverable in exchange
for Stock,  then the  holder of such  Option,  SAR,  Restricted  Stock  Award or
Restricted  Stock Unit shall  thereafter  be entitled to purchase or receive (in
lieu of the  number  of shares  of Stock  that the  holder  would  otherwise  be
entitled  to  purchase  or  receive)  the  number  of  shares  of  stock,  other
securities,  cash or property to which such number of shares of Stock would have
been  entitled in  connection  with the  Restructure  (and,  for Options,  at an
aggregate  exercise  price  equal to the  Exercise  Price  that  would have been
payable if that number of Total Shares had been purchased on the exercise of the
Option immediately before the consummation of the Restructure).

     10.  General Provisions.

         (a) Transferability.



                                      -16-





             (i) Permitted Transferees.  The Committee may,  in its  discretion,
permit a  Participant  to  transfer  all or any  portion  of an  Option or Stock
Appreciation  Right,  or authorize all or a portion of such Awards to be granted
to an Eligible Person to be on terms which permit transfer by such  Participant;
provided that, in either case the  transferee or transferees  must be any child,
stepchild,  grandchild, parent, stepparent,  grandparent, spouse, former spouse,
sibling,    niece,    nephew,    mother-in-law,    father-in-law,    son-in-law,
daughter-in-law,    brother-in-law,   or   sister-in-law,   including   adoptive
relationships,  in each case with respect to the Participant, any person sharing
the Participant's  household (other than a tenant or employee of the Company), a
trust in which  these  persons  have more than fifty  percent of the  beneficial
interest,  a foundation in which these persons (or the Participant)  control the
management  of  assets,  and any other  entity in which  these  persons  (or the
Participant) own more than fifty percent of the voting interests  (collectively,
"Permitted   Transferees");   provided   further  that,  (X)  there  may  be  no
consideration  for any such  transfer  and (Y)  subsequent  transfers  of Awards
transferred as provided above shall be prohibited  except  subsequent  transfers
back to the  original  holder  of the  Award and  transfers  to other  Permitted
Transferees of the original holder. Agreements evidencing Awards with respect to
which such  transferability  is authorized at the time of grant must be approved
by the Committee,  and must expressly  provide for  transferability  in a manner
consistent with this Subsection 10(a)(i).

             (ii)  Qualified  Domestic  Relations  Orders.   An  Option,   Stock
Appreciation Right, Restricted Stock Unit Award or Restricted Stock Award may be
transferred,  to a Permitted Transferee,  pursuant to a domestic relations order
entered or approved by a court of competent  jurisdiction  upon  delivery to the
Company of written notice of such transfer and a certified copy of such order.

             (iii) Other Transfers. Except as expressly permitted by Subsections
10(a)(i) and 10(a)(ii),  Awards shall not be transferable  other than by will or
the laws of descent and distribution.  Notwithstanding  anything to the contrary
in this Section 10, an Incentive  Stock Option shall not be  transferable  other
than by will or the laws of descent and distribution.

             (iv) Effect of Transfer.  Following the  transfer of  any  Award as
contemplated by Subsections 10(a)(i),  10(a)(ii) and 10(a)(iii),  (A) such Award
shall continue to be subject to the same terms and conditions as were applicable
immediately  prior to transfer,  provided that the term  "Participant"  shall be
deemed to refer to the Permitted  Transferee,  the  recipient  under a qualified
domestic  relations  order,  the estate or heirs of a deceased  Participant,  or
other  transferee,  as  applicable,  to the  extent  appropriate  to enable  the
Participant to exercise the  transferred  Award in accordance  with the terms of
this Plan and  applicable  law and (B) the  provisions of the Award  relating to
exercisability  hereof shall continue to be applied with respect to the original
Participant and,  following the occurrence of any such events described  therein
the Awards shall be exercisable by the Permitted Transferee, the recipient under
a  qualified  domestic  relations  order,  the  estate  or heirs  of a  deceased
Participant,  or other transferee, as applicable, only to the extent and for the
periods that would have been applicable in the absence of the transfer.

             (v) Procedures  and  Restrictions.   Any  Participant  desiring  to
     transfer an Award as permitted  under  Subsections  10(a)(i),  10(a)(ii) or
10(a)(iii) shall make  application  therefor in the manner and time specified by
the Committee and shall comply with such other requirements as the Committee may
require to assure compliance with all applicable  securities laws. The Committee
shall  not give  permission  for such a  transfer  if (A) it would  give rise to
short-swing  liability under section 16(b) of the Exchange Act or (B) it may not
be made in compliance with all applicable federal,  state and foreign securities
laws.

             (vi) Registration.  To the extent  the  issuance  to any  Permitted
Transferee of any shares of Stock  issuable  pursuant to Awards  transferred  as
permitted  in this Section  10(a) is not  registered  pursuant to the  effective
registration statement of the Company generally covering the shares to be issued
pursuant to this Plan to initial  holders of Awards,  the Company shall not have
any  obligation to register the issuance of any such shares of Stock to any such
transferee.

         (b) Taxes.  The Company and any  Subsidiary is  authorized to  withhold
from any Award  granted,  or any  payment  relating to an Award under this Plan,
including from a distribution  of Stock,  amounts of withholding and other taxes
due or  potentially  payable in  connection  with any  transaction  involving an
Award,  and to take such other  action as the  Committee  may deem  advisable to


                                      -17-





enable the Company and  Participants  to satisfy  obligations for the payment of
withholding  taxes  and  other  tax  obligations  relating  to any  Award.  This
authority shall include authority to withhold or receive Stock or other property
and to make cash payments in respect  thereof in satisfaction of a Participant's
tax  obligations,  either on a mandatory or elective  basis in the discretion of
the Committee.

         (c) Changes to this  Plan and  Awards.  The  Board  may  amend,  alter,
suspend,  discontinue  or terminate  this Plan or the  Committee's  authority to
grant  Awards  under  this  Plan   without  the  consent  of   stockholders   or
Participants,  except that any amendment or  alteration to this Plan,  including
any  increase in any share  limitation,  shall be subject to the approval of the
Company's  stockholders  not later than the annual  meeting next  following such
Board  action if such  stockholder  approval is required by any federal or state
law or  regulation  or the rules of any stock  exchange or  automated  quotation
system  on which the  Stock  may then be  listed  or  quoted,  and the Board may
otherwise,  in its  discretion,  determine  to submit other such changes to this
Plan to  stockholders  for approval;  provided  that,  without the consent of an
affected  Participant,  no such Board action may materially and adversely affect
the rights of such  Participant  under any  previously  granted and  outstanding
Award. The Committee may waive any conditions or rights under, or amend,  alter,
suspend,  discontinue or terminate any Award  theretofore  granted and any Award
agreement relating thereto,  except as otherwise provided in this Plan; provided
that, without the consent of an affected  Participant,  no such Committee action
may materially and adversely  affect the rights of such  Participant  under such
Award.

         (d) Limitation on Rights Conferred  under Plan.  Neither this  Plan nor
any action taken  hereunder shall be construed as (i) giving any Eligible Person
or Participant  the right to continue as an Eligible Person or Participant or in
the employ or service of the Company or a Subsidiary,  (ii)  interfering  in any
way with the right of the Company or a  Subsidiary  to  terminate  any  Eligible
Person's or  Participant's  employment  or service at any time,  (iii) giving an
Eligible Person or Participant any claim to be granted any Award under this Plan
or to be  treated  uniformly  with other  Participants  and  employees,  or (iv)
conferring  on a Participant  any of the rights of a stockholder  of the Company
unless and until the  Participant is duly issued or transferred  shares of Stock
in accordance with the terms of an Award.

         (e) Unfunded Status of Awards.  This Plan is  intended to constitute an
"unfunded" plan for certain incentive awards.

         (f) Nonexclusivity of this Plan.  Neither the adoption  of this Plan by
the Board nor its  submission  to the  stockholders  of the Company for approval
shall be construed as creating  any  limitations  on the power of the Board or a
committee  thereof  to adopt such other  incentive  arrangements  as it may deem
desirable,  including  incentive  arrangements  and awards  which do not qualify
under  section  162(m)  of the Code.  Nothing  contained  in this Plan  shall be
construed  to prevent the Company or any  Subsidiary  from taking any  corporate
action which is deemed by the Company or such Subsidiary to be appropriate or in
its best  interest,  whether or not such action would have an adverse  effect on
this Plan or any Award made under this Plan. No employee,  beneficiary  or other
person shall have any claim against the Company or any Subsidiary as a result of
any such action.

         (g) Severability.  If any provision of this Plan is  held to be illegal
or invalid for any reason,  the  illegality or  invalidity  shall not affect the
remaining provisions hereof, but such provision shall be fully severable and the
Plan shall be construed and enforced as if the illegal or invalid  provision had
never been  included  herein.  If any of the terms or provisions of this Plan or
any Award agreement conflict with the requirements of Rule 16b-3 (as those terms
or provisions  are applied to Eligible  Persons who are subject to section 16(b)
of the Exchange Act) or section 422 of the Code (with respect to Incentive Stock
Options), then those conflicting terms or provisions shall be deemed inoperative
to the extent they so conflict with the  requirements  of Rule 16b-3 (unless the
Board or the Committee,  as appropriate,  has expressly determined that the Plan
or such Award  should not comply  with Rule  16b-3) or section  422 of the Code.
With  respect to  Incentive  Stock  Options,  if this Plan does not  contain any
provision  required to be included  herein under  section 422 of the Code,  that
provision  shall be deemed to be  incorporated  herein  with the same  force and
effect  as if that  provision  had  been  set out at  length  herein;  provided,
further,  that,  to the  extent  any Option  that is  intended  to qualify as an
Incentive Stock Option cannot so qualify,  that Option (to that extent) shall be
deemed an Option not subject to section 422 of the Code for all  purposes of the
Plan.


                                      -18-





         (h) Governing Law. All questions arising with respect to the provisions
of the Plan and Awards shall be  determined  by  application  of the laws of the
State of  Delaware,  without  giving  effect to any  conflict of law  provisions
thereof,  except to the extent  Delaware  law is  preempted  by federal law. The
obligation  of the Company to sell and  deliver  Stock  hereunder  is subject to
applicable  federal  and  state  laws and to the  approval  of any  governmental
authority  required in connection  with the  authorization,  issuance,  sale, or
delivery of such Stock.

         (i) Conditions to  Delivery of Stock.  Nothing  herein or  in any Award
granted  hereunder or any Award agreement shall require the Company to issue any
shares  with  respect to any Award if that  issuance  would,  in the  opinion of
counsel for the Company,  constitute a violation  of the  Securities  Act or any
similar or  superseding  statute or statutes,  any other  applicable  statute or
regulation,  or the rules of any  applicable  securities  exchange or securities
association,  as then in  effect.  At the time of any  exercise  of an Option or
Stock  Appreciation  Right,  or at the time of any grant of a  Restricted  Stock
Award or Restricted Stock Unit, the Company may, as a condition precedent to the
exercise  of such  Option  or  Stock  Appreciation  Right or  settlement  of any
Restricted  Stock Award or Restricted  Stock Unit,  require from the Participant
(or in the event of his death, his legal  representatives,  heirs,  legatees, or
distributees)  such written  representations,  if any,  concerning  the holder's
intentions  with regard to the retention or  disposition  of the shares of Stock
being acquired  pursuant to the Award and such written covenants and agreements,
if any,  as to the  manner of  disposal  of such  shares  as, in the  opinion of
counsel to the Company,  may be necessary to ensure that any disposition by that
holder (or in the event of the holder's death, his legal representatives, heirs,
legatees, or distributees) will not involve a violation of the Securities Act or
any similar or superseding  statute or statutes,  any other  applicable state or
federal statute or regulation, or any rule of any applicable securities exchange
or securities  association,  as then in effect. No Option or Stock  Appreciation
Right shall be exercisable  and no settlement of any  Restricted  Stock Award or
Restricted Stock Unit shall occur with respect to a Participant unless and until
the holder  thereof  shall have paid cash or property to, or performed  services
for, the Company or any of its Subsidiaries that the Committee believes is equal
to or greater in value than the par value of the Stock subject to such Award.
