                        PIONEER NATURAL RESOURCES COMPANY
                          EMPLOYEE STOCK PURCHASE PLAN

             (Amended and Restated Effective as of December 9, 2005)


     This Amended and Restated PIONEER NATURAL  RESOURCES COMPANY EMPLOYEE STOCK
PURCHASE  PLAN (this "Plan") is made and executed by Pioneer  Natural  Resources
Company, a Delaware Corporation (the "Company").

                          W I T N E S S E T H T H A T:

     WHEREAS the Pioneer Natural  Resources Company Employee Stock Purchase Plan
was Adopted by the Board of Directors of the Company (the  "Board') and approved
by the stockholders of the Company on August 7, 1997; and

     WHEREAS,  the Company now desires to restate the Pioneer Natural  Resources
Company  Employee Stock Purchase Plan to incorporate  prior  amendments and make
certain other changes;

     NOW,  THEREFORE,  in  consideration  of the  premises  and  pursuant to the
authority  reserved  thereunder,  the Pioneer Natural Resources Company Employee
Stock Purchase Plan is hereby amended by restatement in its entirety,  effective
as of December 9, 2005, to read as follows:

     1.   Purpose. The purpose of the Plan is to provide eligible employees with
an incentive to advance the interests of the Company by affording an opportunity
to purchase stock of the Company at a favorable price.

     2.   Administration  Of  The Plan.  The  Plan  shall  be  administered by a
committee  of, and  appointed  by, the Board (the  "Committee").  Subject to the
provisions of the Plan, the Committee  shall interpret and construe the Plan and
all options granted under the Plan;  shall make such rules as it deems necessary
for the proper  administration of the Plan; shall make all other  determinations
necessary  or  advisable  for the  administration  of the  Plan,  including  the
determination  of  eligibility  to  participate  in the Plan and the amount of a
Participant's (as defined in subparagraph 6(b)) option under the Plan; and shall
correct any defect or supply any omission or reconcile any  inconsistency in the
Plan or in any  option  granted  under the Plan in the  manner and to the extent
that the Committee  deems desirable to carry the Plan or any option into effect.
The Committee shall, in its sole discretion  exercised in good faith,  make such
decisions or determinations and take such actions as it deems  appropriate;  and
all such  decisions,  determinations  and actions taken or made by the Committee
pursuant to this and the other paragraphs of the Plan shall be conclusive on all
parties.  The Committee shall not be liable for any decision,  determination  or
action taken in good faith in connection with the administration of the Plan.

                                      -2-







     3.   Participating Companies.  Each present and future parent or subsidiary
corporation of the Company (within the meaning of Sections 424(e) and (f) of the
Internal  Revenue Code of 1986, as amended (the "Code")) that is eligible by law
to participate in the Plan shall be a "Participating  Company" during the period
that such  corporation  is such a parent or  subsidiary  corporation;  provided,
however,  that the  Committee may at any time and from time to time, in its sole
discretion,  terminate a Participating  Company's Plan participation;  provided,
further  however,  that any  foreign  parent or  subsidiary  corporation  of the
Company shall be eligible to  participate  in the Plan only upon approval of the
Board or the Committee.  Any Participating Company may, by appropriate action of
its board of directors,  terminate its  participation  in the Plan.  Transfer of
employment  among the Company and  Participating  Companies (and among any other
parent or  subsidiary  corporation  of the  Company)  shall not be  considered a
termination of employment hereunder.

     4.   Eligibility.  All employees, other than officers,  of the Company  and
the  Participating  Companies  who have  been  employed  by the  Company  or any
Participating  Company (including any predecessor  company) for at least six (6)
months  (including any authorized  leave of absence meeting the  requirements of
Treasury  Regulation  ss.  1.421  -7(h)(2)) as of the  applicable  date of grant
(defined below) and who are customarily  employed at least 20 hours per week and
at least five (5) months per year shall be eligible to  participate in the Plan;
provided,  however,  that no option  shall be  granted  to an  employee  if such
employee,  immediately  after the option is granted,  owns stock possessing five
percent or more of the total  combined  voting  power or value of all classes of
stock of the  Company or of its parent or  subsidiary  corporation  (within  the
meaning of Sections 423(b)(3) and 424(d) of the Code) ("Eligible Employee").

     5.   Stock Subject To the Plan.  Subject to the provisions  of paragraph 12
(relating to adjustment upon changes in stock),  the aggregate  number of shares
which may be sold  pursuant to options  granted  under the Plan shall not exceed
750,000 shares of the authorized  common stock, par value $.01 per share, of the
Company (the "Stock"),  which shares may be unissued shares,  reacquired shares,
or shares  bought on the  market  for  purposes  of the Plan.  Should any option
granted  under the Plan expire or terminate  prior to its exercise in full,  the
shares  theretofore  subject  to such  option  may again be subject to an option
granted under the Plan. Any shares which are not subject to outstanding  options
upon the termination of the Plan shall cease to be subject to the Plan.

     6.   Grant of Options.

          (a) General Statement;  "Date of  Grant;"  "Option  Period;"  "Date Of
     Exercise."  Upon the effective  date of  the Plan and  continuing while the
     Plan remains in force,  the Company  shall offer  options under the Plan to
     all Eligible  Employees to purchase  shares of Stock.  Except  as otherwise
     determined by the Committee,  these options shall  be granted on January 1,
     1998, and, thereafter,  on the first day of January of each subsequent year
     (each of which dates is herein referred to as a "date of grant").  The term
     of each option granted shall be for a period of  eight (8) months beginning
     on date  of grant  and ending  on August 31  (each such  8-month  period is
     herein  referred  to as an  "option period").  The last day of  each option


                                      -3-






     period is herein referred to as a "date of exercise."  The number of shares
     subject  to each  option shall  be the  quotient of the sum  of the payroll
     deductions  withheld  on  behalf  of  each  Participant in  accordance with
     subparagraph  6(b),  the payments  made  by such  Participant  pursuant  to
     subparagraph 6(f) during the option period  and any  amount carried forward
     from the preceding option period pursuant to subparagraph 7(a),  divided by
     the  "option price"  (defined in subparagraph 7(b) of the Stock,  excluding
     all fractions;  provided,  however,  that the maximum number of shares that
     may be subject to any option may not exceed one thousand (1000) (subject to
     adjustment as provided in paragraph 12).

          (b) Election to Participate;  Payroll Deduction Authorization.  Except
     as provided in  subparagraph 6(f),  an Eligible Employee may participate in
     the  Plan  only by  means  of payroll  deduction.  Except  as  provided in'
     subparagraph 6(g), each Eligible Employee who elects to  participate in the
     Plan  (each such  participating  Eligible Employee  being a  "Participant")
     shall deliver  to the  Company,  within the  time period  prescribed by the
     Committee, a written payroll deduction authorization on a form  prepared by
     the Committee whereby he gives notice of his election to participate in the
     Plan as of  the next following  date of grant, and whereby he designates an
     integral percentage  or specific amount of his  "eligible compensation" (as
     defined in subparagraph 6(d)) to be deducted from his compensation for each
     pay period and  credited to  a book entry account  established in his name.
     The designated percentage or specific amount may  not result in a deduction
     during any  payroll period  of an amount  less than $20.00.  The designated
     percentage or specific amount may not exceed  either of the  following: (i)
     15% of  the amount of  eligible  compensation  from which the  deduction is
     made; or (ii) an amount which will result in noncompliance with the $25,000
     limitation stated in subparagraph 6(e).

          (c) Changes  in  Payroll   Authorization.   Except   as  provided   in
     subparagraph 8(a),  the  payroll deduction  authorization  referred  to  in
     subparagraph 6(b) may not be changed during the option period.

          (d) "Eligible Compensation" Defined.  The term "eligible compensation"
     means the gross (before taxes are  withheld) total of all wages,  salaries,
     commissions and bonuses received during the option period, except that such
     term shall include  elective contributions made on  an employee's behalf by
     the Company or a  Participating Company  that are not includable  in income
     under  Section 125 or  Section 402(e)(3)  of the Code.  Notwithstanding the
     foregoing,  "eligible   compensation"  shall   not  include  (i)   employer
     contributions  to or  payments  from  any  deferred  compensation  program,
     whether such program is qualified under  Section 401(a) of  the Code (other
     than amounts  considered as employer contributions under  Section 402(e)(3)
     of the  Code) or  nonqualified, (ii)  amounts realized from  the receipt or
     exercise of a stock option that is not an incentive stock option within the
     meaning of  Section 422  of the  Code, (iii)  amounts realized  at the time
     property described in Section 83 of the  Code is freely  transferable or no
     longer subject  to a substantial risk  of forfeiture, (iv) amounts realized
     as a result of an election described in Section 83(b) of  the Code, and (v)
     any amount realized as a result  of a disqualifying disposition  within the
     meaning of Section 421(a) of the Code.



                                      -4-






          (e) $25,000  Limitation.  No  Eligible  Employee  shall  be granted an
     option under the Plan to the extent such grant would permit him to purchase
     Stock under  the Plan and under all other  employee stock purchase plans of
     the Company and its parent  and subsidiary corporations  (as such terms are
     defined in Section 424(e)  and (f) of the  Code) to accrue  at a rate which
     exceeds $25,000 of the  Fair Market Value of Stock (determined  at the time
     the option  is granted) for each  calendar year  in which  any such  option
     granted to such employee is outstanding at any time (within  the meaning of
     Section 423(b)(8) of the Code).

          (f) Leaves of Absence.  During a paid leave of absence approved by the
     Company  and   meeting  the  requirements   of  Treasury   Regulation   ss.
     1.421-7(h)(2),  a Participant's  elected payroll deductions shall continue.
     If a Participant takes an  unpaid leave of absence that is  approved by the
     Company or a  Participating Company and meets  the requirements of Treasury
     Regulation   ss.  1.421-7(h)(2),   then  such   Participant  may   continue
     participation in the Plan by cash payments to the Company on his normal pay
     days equal to the reduction in his payroll deductions  caused by his leave.
     If a  Participant  on  such leave  fails to  make such  payments,  or  if a
     Participant takes a leave of absence that is not described in the preceding
     provisions of  this subparagraph 6(f),  then the Committee  shall determine
     whether the Participant shall be considered to have withdrawn from the Plan
     pursuant  to   the  provisions  of   paragraph  8  hereof  or  whether  the
     Participant's payroll  deductions shall remain subject to the Plan and used
     to exercise options on the next following date of exercise.

          (g) Continuing  Election.  Unless  a  Participant is  notified  to the
     contrary,  a Participant  (i) who has  elected to  participate in  the Plan
     pursuant to  subparagraph 6(b) as of a date of grant  and (ii) who takes no
     action to change  or revoke such election  as of the next following date of
     grant  and/or as  of  any  subsequent  date  of  grant  prior  to  any such
     respective date of  grant, shall be deemed to have made the same  election,
     including the same attendant payroll deduction authorization, for such next
     following and/or subsequent date(s) of grant as  was in effect for the date
     of grant for which he made such election to participate.  A Participant who
     wants to  discontinue  participation  in the  Plan for  a subsequent option
     period  shall deliver  to the  Company a  notice of  withdrawal pursuant to
     paragraph 8, at least thirty (30) days prior to the beginning of the option
     period.

     7.   Exercise of Options.

          (a) General Statement.  Each Eligible Employee who is a Participant in
     the Plan, automatically and without any act on his part, shall be deemed to
     have exercised his option  on each date of  exercise to the extent that the
     cash balance then  in his account under the Plan is  sufficient to purchase
     at the  "option price"  (as defined in  subparagraph 7(b))  whole shares of
     Stock. Any balance remaining in  his account after payment of  the purchase
     price of those  whole shares may,  at the discretion of the Company, either
     be refunded to  him as soon as  practicable after each date of exercise, or
     carried forward and used towards the  purchase of whole shares  in the next
     following option period.

                                      -5-






          (b) "Option Price" Defined.  The option price per share of Stock to be
     paid by each  Eligible Employee on each  exercise of his option shall be an
     amount equal to the lesser of 85% of the  Fair Market Value of the Stock on
     the date of  exercise or  on the  date of grant. For all purposes under the
     Plan, the "Fair Market Value" of a share of Stock means,  for a  particular
     day:

              (i) If shares of Stock of the same class are listed or admitted to
          unlisted trading  privileges on  any national  or  regional securities
          exchange at the date  of determining the  Fair Market Value,  then the
          last reported sale price,  regular way,  on the composite tape of that
          exchange on that business day or, if no such sale  takes place on that
          business day, the average of the closing bid and asked prices, regular
          way,  in  either  case  as  reported  in  the  principal  consolidated
          transaction  reporting  system  with respect  to securities  listed or
          admitted  to unlisted  trading privileges on that  securities exchange
          or, if no such  closing prices  are available  for that day,  the last
          reported  sale price,  regular way,  on the  composite  tape  of  that
          exchange on the last business day before the date in question; or

             (ii) If  shares  of  Stock  of the  same  class  are not  listed or
          admitted  to unlisted trading  privileges as provided in  subparagraph
          (i) and  if sales prices  for shares of Stock of the same class in the
          over-the-counter  market are reported  bythe  National  Association of
          Securities  Dealers,   Inc.  Automated   Quotations,  Inc.  ("NASDAQ")
          National Market System (or a  similar system  then in use) at the date
          of determining  the  Fair Market Value,  then the last reported  sales
          price so reported on that business day or, if no such sale takes place
          on that business day, the average of the high bid and low asked prices
          so reported or, if no such prices are available for that day, the last
          reported  sale price so  reported on the  last business day before the
          date in question; or

            (iii) If  shares  of  Stock  of  the  same class  are not  listed or
          admitted to unlisted  trading  privileges as provided in  subparagraph
          (i) and  sales  prices for shares  of Stock of  the same class are not
          reported by the  NASDAQ National  Market System  (or a  similar system
          then in use)  as provided  in subparagraph  (ii), and if bid and asked
          prices for shares of  Stock of the same class in the  over-the-counter
          market are reported by NASDAQ (or, if not so reported, by the National
          Quotation  Bureau Incorporated)  at the date of  determining  the Fair
          Market Value, then the average of the high bid and low asked prices on
          that  business day or,  if no such prices are  available for that day,
          the average of the high bid and low asked  prices on the last business
          day before the date in question; or

             (iv) If  shares  of  Stock  of  the  same class  are  not listed or
          admitted to unlisted  trading privileges as  provided in  subparagraph
          (i) and sales prices or bid and asked prices therefor are not reported
          by NASDAQ (or the  National Quotation Bureau Incorporated) as provided
          in subparagraph (ii) or subparagraph (iii) at the  date of determining
          the Fair Market Value, then the  value determined in good faith by the
          Committee, which determination shall be conclusive  for all  purposes;
          or


                                      -6-





              (v) If shares of Stock of the same class are listed or admitted to
          unlisted trading privileges  as provided in  subparagraph (i) or sales
          prices or bid and asked prices therefor are reported by NASDAQ (or the
          National Quotation  Bureau Incorporated)  as provided  in subparagraph
          (ii) or subparagraph (iii) at  the date of determining the Fair Market
          Value, but the volume of trading is so low that the Board of Directors
          determines in  good faith that such  prices are  not indicative of the
          fair value of the Stock,  then the value  determined in  good faith by
          the  Committee,  which  determination  shall  be  conclusive  for  all
          purposes notwithstanding the provisions of subparagraphs (i),  (ii) or
          (iii).

          (c) Delivery  of  Stock.  As  soon  as  practicable after each date of
     exercise,  the  Company  shall deposit  into each  Participant's  brokerage
     account  maintained for the  purposes of holding  Stock under this Plan and
     other employee benefit plans of the Company, the number of  whole shares of
     Stock purchased by  such Participant  upon exercise of  his or her  options
     granted  hereunder.  Except  as  provided  in  the  immediately   following
     sentence,  shares  of  Stock  purchased  upon  exercise of  options granted
     hereunder shall  be  uncertificated and  evidenced by  book entry  into the
     brokerage  accounts  described  above.  Upon  written  request made  by any
     Participant  to  the  Company,  the  Company  shall  arrange,  as  soon  as
     practicable  after  receipt  of  any  such  request,  to  deliver  to  such
     Participant a  certificate  representing  any or  all  such  uncertificated
     shares of Stock.  In the event the  Company is  required to obtain from any
     commission or agency authority  to issue any shares of Stock hereunder, the
     Company shall seek  to obtain  such authority.  Inability of the Company to
     obtain from any such commission or  agency authority which  counsel for the
     Company deems  necessary for  the lawful issuance  of any  shares of  Stock
     shall relieve the  Company from liability  to any  Participant  in the Plan
     except to  return  to the  Participant the  amount of  the  balance  in the
     Participant's account.  The Company may cause any Stock certificates issued
     in connection  with the  exercise  of  options under the  Plan to bear such
     legend or legends, and the Company may take such other actions, as it deems
     appropriate in  order to reflect  the provisions of  this subparagraph 7(c)
     and to  assure  compliance  with  applicable  securities laws.  Neither the
     Company nor the Committee shall have  any liability with respect to a delay
     in the  delivery of Stock or a  certificate  pursuant to this  subparagraph
     7(c).

     8.   Withdrawal from the Plan.

          (a) General Statement.  Any Participant may withdraw in whole from the
     Plan at any  time prior  to 30 days before  the exercise date relating to a
     particular option  period.  Partial withdrawals  shall not be permitted.  A
     Participant who wishes to withdraw from the Plan must timely deliver to the
     Company  a notice  of withdrawal  on a form  prepared by the Committee. The
     Company,  promptly  following  the time  when the  notice of  withdrawal is
     delivered, shall refund to the  Participant the  amount of the cash balance
     in his account under the Plan; and thereupon, automatically and without any
     further  act on  his  part,  his payroll  deduction  authorization  and his
     interest in unexercised options under the Plan shall terminate.


                                      -7-






          (b) Eligibility Following Withdrawal. A Participant who withdraws from
     the Plan shall  not be eligible to  participate in the Plan during the then
     current option period (if any), but shall be eligible to  participate again
     in the Plan in a subsequent option period (provided that he is otherwise an
     Eligible Employee at such time).

     9.   Termination  of  Employment.   If  the  employment  of  a  Participant
terminates  for  any  reason   whatsoever,   his   participation   in  the  Plan
automatically  and without any act on his part shall terminate as of the date of
the termination of his employment. The Company shall refund to him the amount of
the cash balance in his account  under the Plan,  and  thereupon his interest in
unexercised options under the Plan shall terminate.

    10.   Restriction Upon  Assignment of Option.  An option  granted under  the
     Plan shall not be pledged,  assigned or transferred  otherwise than by will
or the laws of descent and distribution.  Each option shall be exercisable, only
by the  Participant  to whom granted  during such  Participant's  lifetime.  The
Company  shall  not  recognize  and  shall  be under  no duty to  recognize  any
assignment  or purported  assignment  by a  Participant  of his option or of any
rights  under his option,  and any such attempt may be treated by the Company as
an election to withdraw from the Plan the notice for which has been delivered to
the Company.

    11.   No Rights of Stockholder Until Stock Issued. With respect to shares of
Stock  subject  to  an  option,  a  Participant  shall  not  be  deemed  to be a
stockholder,  and he  shall  not  have  any of the  rights  or  privileges  of a
stockholder,  until,  (a)  shares  of Stock  are  deposited  into his  brokerage
account,  as described in  subparagraph  7(c) hereof,  or (b) a certificate  for
shares of Stock is issued on his behalf, whichever occurs first."

    12.   Adjustments Upon Changes in Stock.

          (a) Adjustments  Upon Changes in  Capitalization.  In the event of any
    change in the  number or  kind of  outstanding shares  of Stock  subject  to
    options hereunder effected without receipt of consideration  therefor by the
    Company,  by reason of a stock dividend,  stock split, combination, exchange
    of shares or  other  recapitalization,  merger,  or otherwise,  in which the
    Company  is the  surviving  corporation,  an  appropriate  and proportionate
    adjustment shall be made in the number or kind of shares as to which options
    are or  may be  granted  hereunder.  A corresponding adjustment changing the
    number  or  kind of  shares  allocated to  unexercised  options or  portions
    thereof,  which shall  have been  granted prior  to any  such  change, shall
    likewise be made.  Any such adjustment,  however, in the outstanding options
    shall  be  made  without  change  in  the  total  price  applicable  to  the
    unexercised portion  of the option but with a  corresponding adjustment,  if
    appropriate, in  the price for each  share of  Stock  covered by the option.
    In the event of a dispute  concerning such adjustment,  the decision  of the
    Committee  shall be conclusive.  The number of  shares subject to any option
    granted  hereunder shall be automatically  reduced by any fraction  included
    therein which  results from  any adjustment  made pursuant  to this  Section
    12(a).

          (b) Adjustments Upon  Change of Control.  Further,  in the  event of a
    Change of Control (as defined below) of the Company, the Committee shall, at


                                      -8-





    its  option, (i)  substitute for the  shares of  the Company  subject to the
    unexercised portions of  such outstanding options  an appropriate  number of
    shares of  each class  of stock  or other  securities  of the reorganized or
    merged   or  consolidated   corporation  which   were  distributed   to  the
    stockholders of the Company with respect to  the same class of shares of the
    Company (or, as appropriate, in the case of an acquisition of the Company by
    another corporation,  substitute the shares of the acquiring corporation for
    the  shares of  the Company);  or  (ii)  cancel  all such  options as of the
    effective  date of  any such  transaction  by giving  notice to  each holder
    thereof  or his  personal  representative  of its  intention to do so and by
    permitting the holders thereof to exercise of all such  outstanding options,
    without regard to any other provisions of the Plan, during the 30-day period
    immediately  preceding  such  effective  date;  or  (iii)  allow the options
    granted under the  Plan to remain  outstanding  without any modifications or
    amendments.

          (c) Change of Control Defined.  For purposes of  subparagraph 12(b) of
    the Plan, a  "Change of  Control"  shall have  occurred if  (and only  if) a
    "Change  in  Control"  occurs under  the Company's  Long-Term Incentive Plan
    dated  August 7, 1997,  as  amended,  or  under any  successor plan  to such
    Long-Term Incentive Plan, as any such plan may from time to time be amended.

    13.   Use of Funds;  No Interest  Paid.  All  funds received  or held by the
Company  under the Plan shall be included  in the  general  funds of the Company
free of any  trust  or  other  restriction,  and may be used  for any  corporate
purpose. No interest shall be paid to any Participant or credited to his account
under the Plan.

    14.   Term of the Plan.  The Plan shall be  effective as of January 1, 1998.
If not sooner  terminated  under the  provisions of paragraph 15, the Plan shall
terminate upon and no further options shall be granted after December 31, 2007.

    15.   Amendment or Termination of the Plan.  The Board in its discretion may
terminate the Plan at any time with respect to any shares for which options have
not theretofore  been granted.  The Board shall have the right to alter or amend
the Plan or any part thereof from time to time; provided,  that no change in any
option  theretofore  granted  may be made which  would  impair the rights of the
Participant without the consent of such Participant; and provided, further, that
the  Board may not make any  alteration  or  amendment  which  would  materially
increase  the benefits  accruing to  Participants  under the Plan,  increase the
aggregate number of shares which may be issued pursuant to the provisions of the
Plan  (other  than as a result of the  anti-dilution  provisions  of the  Plan),
change the class of  individuals  eligible  to receive  options  under the Plan,
extend the term of the Plan, cause options issued under the Plan to fail to meet
the  requirements for employee stock purchase plans as defined in Section 423 of
the  Code,  or  otherwise   modify  the   requirements  as  to  eligibility  for
participation  in the Plan  without  the  approval  of the  stockholders  of the
Company.

    16.   Securities Laws. The Company shall not be obligated to issue any Stock
pursuant  to any  option  granted  under  the Plan at any time  when the  shares
covered by such  option have not been  registered  under the  Securities  Act of
1933, as amended, and such other state and federal laws, rules or regulations as
the  Company or the  Committee  deems  applicable  and,  in the opinion of legal


                                      -9-





counsel  for  the  Company,   there  is  no  exemption  from  the   registration
requirements of such laws,  rules or regulations  available for the issuance and
sale of such shares.  Further,  all Stock acquired pursuant to the Plan shall be
subject to the Company's policy or policies,  if any, concerning compliance with
securities laws and regulations, as the same may be amended from time to time.

    17.   No Restriction on  Corporate  Action.  Nothing  contained in  the 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 the Plan or any award  made  under  the  Plan.  No  employee,
beneficiary  or other  person  shall have any claim  against  the Company or any
subsidiary as a result of any such action.
