          Definitions of Oil and Gas Terms and Conventions Used Herein

       Within this Report,  the following oil and gas terms and conventions have
specific  meanings:  "Bbl" means a standard  barrel  containing 42 United States
gallons;  "BOE" means a barrel of oil  equivalent  and is a standard  convention
used to express oil and gas volumes on a comparable oil equivalent basis;  "Btu"
means British  thermal unit and is a measure of the amount of energy required to
raise the temperature of one pound of water one degree Fahrenheit; "LIBOR" means
London Interbank Offered Rate, which is a market rate of interest; "MMBtu" means
one million Btus; "MBbl" means one thousand Bbls; "MBOE" means one thousand BOE;
"Mcf"  means one  thousand  cubic feet and is a measure of natural  gas  volume;
"MMcf" means one million  cubic feet;  "NGL" means  natural gas liquid;  "NYMEX"
means The New York  Mercantile  Exchange;  "proved  reserves" mean the estimated
quantities of crude oil,  natural gas, and natural gas liquids which  geological
and engineering data demonstrate with reasonable  certainty to be recoverable in
future  years  from known  reservoirs  under  existing  economic  and  operating
conditions,  i.e.,  prices and costs as of the date the estimate is made. Prices
include consideration of changes in existing prices provided only by contractual
arrangements, but not on escalations based upon future conditions.
       (i) Reservoirs   are  considered  proved  if  economic  producibility  is
supported by either actual production or conclusive  formation test. The area of
a reservoir  considered proved includes (A) that portion  delineated by drilling
and  defined  by  gas-oil  and/or  oil-water  contacts,  if  any;  and  (B)  the
immediately  adjoining  portions  not yet drilled,  but which can be  reasonably
judged as  economically  productive  on the basis of  available  geological  and
engineering  data. In the absence of information on fluid  contacts,  the lowest
known structural  occurrence of hydrocarbons  controls the lower proved limit of
the reservoir.
       (ii) Reserves  which can be produced economically  through application of
improved  recovery  techniques  (such as fluid  injection)  are  included in the
"proved"  classification  when  successful  testing by a pilot  project,  or the
operation of an installed  program in the  reservoir,  provides  support for the
engineering analysis on which the project or program was based.
       (iii) Estimates of proved reserves do not include the following:  (A) oil
that may become available from known reservoirs but is classified  separately as
"indicated  additional  reserves";  (B) crude oil,  natural gas, and natural gas
liquids,  the  recovery  of which is  subject  to  reasonable  doubt  because of
uncertainty as to geology, reservoir  characteristics,  or economic factors; (C)
crude oil,  natural gas,  and natural gas  liquids,  that may occur in undrilled
prospects;  and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.

       Gas equivalents  are determined under  the relative energy content method
by using the ratio of 6.0 Mcf of gas to 1.0 Bbl of oil or NGL.

       With  espect to information on the  working interest  in wells,  drilling
locations and acreage,  "net" wells, drilling locations and acres are determined
by multiplying  "gross" wells,  drilling  locations and acres by Pioneer Natural
Resources Company's working interest in such wells, drilling locations or acres.
Unless otherwise  specified,  wells,  drilling  locations and acreage statistics
quoted  herein  represent  gross wells,  drilling  locations or acres;  and, all
currency amounts are expressed in U.S. dollars.

NOTE A.     Organization and Nature of Operations

       Pioneer Natural  Resources  Company  (the  "Company" or  "Pioneer")  is a
Delaware  corporation  whose  common  stock is listed and traded on the New York
Stock Exchange. The Company is an oil and gas exploration and production company
with ownership interests in oil and gas properties located in the United States,
Argentina, Canada, Gabon, South Africa and Tunisia.

NOTE B.     Basis of Presentation

       Presentation.  In the opinion  of management,  the unaudited consolidated
financial  statements  of the Company as of September 30, 2003 and for the three
and nine month periods ended September 30, 2003 and 2002 include all adjustments
and accruals,  consisting only of normal,  recurring accrual adjustments,  which
are necessary for a fair  presentation  of the results for the interim  periods.
These interim results are not necessarily indicative of results for a full year.
Certain amounts in the prior period financial  statements have been reclassified
to conform to the current period presentation.

       Certain  information  and  footnote  disclosures   normally  included  in
financial  statements  prepared in accordance with generally accepted accounting
principles  have been  condensed  or omitted in this Form 10-Q  pursuant  to the
rules and  regulations of the United States  Securities and Exchange  Commission
("SEC").  These consolidated  financial  statements should be read in connection
with the  consolidated  financial  statements and notes thereto  included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2002.

       Adoption of  SFAS 143.  On  January  1,  2003,  the  Company  adopted the
provisions of Statement of Financial  Accounting  Standards No. 143, "Accounting
for Asset Retirement  Obligations"  ("SFAS 143").  SFAS 143 amended Statement of
Financial  Accounting  Standards No. 19, "Financial  Accounting and Reporting by
Oil and Gas Producing Companies" ("SFAS 19") to require that the fair value of a
liability  for an asset  retirement  obligation  be  recognized in the period in
which it is incurred if a reasonable  estimate of fair value can be made.  Under
the provisions of SFAS 143, asset retirement obligations are capitalized as part
of the carrying value of the long-lived asset.  Under the provisions of SFAS 19,
asset retirement obligations were recognized using a cost-accumulation approach.
Prior to the  adoption  of SFAS 143,  the  Company  recorded  significant  asset
retirement obligations through the  unit-of-production  method, except for asset
retirement  obligations that were assumed in business  combinations,  which were
recorded at their estimated fair values on their dates of acquisition.

       The adoption of SFAS 143 resulted in a January 1,  2003 cumulative effect
adjustment  to record (i) a $13.8  million  increase in the  carrying  values of
proved  properties,  (ii) a $26.3 million decrease in accumulated  depreciation,
depletion  and  amortization  of  property,  plant and  equipment,  (iii) a $1.0
million  increase  in  current  abandonment  liabilities,  (iv) a $22.4  million
increase in noncurrent  abandonment  liabilities and (v) a $1.3 million increase
in  Argentine  deferred  income  tax  liabilities.  The net  impact of items (i)
through (v) was to record a gain of $15.4  million,  net of tax, as a cumulative
effect  adjustment  of  a  change  in  accounting  principle  in  the  Company's
Consolidated  Statements  of Operations  upon  adoption on January 1, 2003.  See
Notes C and F for additional  information  regarding the Company's  income taxes
and asset retirement obligations.

       The following  pro forma data  summarizes the Company's net income (loss)
and net  income  (loss)  per share for the three and nine  month  periods  ended
September 30, 2003 and 2002 as if the Company had adopted the provisions of SFAS
143  on  January  1,  2002,  including  aggregate  pro  forma  asset  retirement
obligations on that date of $60.2 million:

       Adoption of  SFAS  145.  On  January 1,  2003,  the  Company a dopted the
provisions of Statement of Financial  Accounting  Standards No. 145, "Rescission
of FASB  Statements  No. 4, 44 and 64,  Amendment of FASB  Statement  No. 13 and
Technical  Corrections"  ("SFAS 145"). Prior to SFAS 145, gains or losses on the
early  extinguishment  of debt were  required  to be  classified  in a company's
periodic consolidated statements of operations as extraordinary gains or losses,
net of associated  income taxes,  after the determination of income or loss from
continuing  operations.  SFAS 145  requires,  except  in the case of  events  or
transactions  of a highly  unusual and infrequent  nature,  that gains or losses
from the early  extinguishment of debt be classified,  on both a prospective and
retrospective basis, as components of a company's income or loss from continuing
operations.  The  adoption  of SFAS 145 did not affect the  Company's  financial
position or liquidity.  Under the  provisions of SFAS 145,  gains or losses from
the early  extinguishment  of debt are recognized in the Company's  Consolidated
Statements  of  Operations,  except in the case of events or  transactions  of a
highly  unusual and  infrequent  nature,  as components of other income or other
expense and are included in the  determination  of income (loss) from continuing
operations.  Accordingly,  extraordinary losses from the early extinguishment of
debt of $2.8 million and $19.5 million  recorded  during the three month periods
ended June 30 and September 30, 2002,  respectively,  have been  reclassified to
other expense.

       Stock-based  compensation.   The   Company   accounts   for   stock-based
compensation  granted  under its  long-term  incentive  plan using the intrinsic
value  method  prescribed  by  Accounting   Principles  Board  Opinion  No.  25,
"Accounting  for  Stock  Issued  to  Employees"  and  related   interpretations.
Stock-based  compensation  expenses  associated  with  option  grants  were  not
recognized  in the  Company's  net  income  (loss)  for the three and nine month
periods ended  September 30, 2003 and 2002, as all options  granted had exercise
prices equal to the market value of the underlying  common stock on the dates of
grant.  Stock-based compensation expense associated with restricted stock awards
is deferred and  amortized to earnings  ratably over the vesting  periods of the
awards.  The  following  table  illustrates  the pro forma  effect on net income
(loss) and net income  (loss) per share as if the  Company  had applied the fair
value recognition  provisions of Statement of Financial Accounting Standards No.
123,  "Accounting  for  Stock-Based  Compensation"  to stock-based  compensation
during the three and nine month periods ended September 30, 2003 and 2002:

NOTE C.     Income Tax Assets

       Since 1998,  the Company has  maintained a valuation  allowance against a
portion of its deferred tax asset position in the United States.  As of December
31,  2002,  the  Company's  deferred tax  valuation  allowances  totaled  $247.0
million,  comprised of $204.3  million of United  States  deferred tax valuation
allowances and $42.7 million of international deferred tax valuation allowances.
Statement of Financial  Accounting  Standards  No. 109 requires that the Company
continually  assess both positive and negative  evidence to determine whether it
is more likely than not that the  deferred  tax assets can be realized  prior to
their expiration. In the third quarter of 2003, the Company concluded that it is
now more  likely  than not that it will  realize  its gross  deferred  tax asset
position  in the United  States  after  giving  consideration  to the  following
specific facts:

o    Over the past several  years,  the Company has been steadily  improving its
     portfolio of assets,  including  significant proved reserve discoveries and
     follow-up  development  projects  that have  recently  started to  produce.
     Specifically, Pioneer completed development activities and began production
     operations on its Canyon  Express gas project in September  2002 and on its
     Company-operated  Falcon  field gas project in March 2003.  The  production
     performance  to-date  and the  reservoir  data  that has  been  accumulated
     through  September 30, 2003 on these projects provide  assurance that these
     projects will recover the reserves as predicted.

o    During the three months ended  September  30, 2003,  the Company  announced
     additional  Falcon area  discoveries  in the Tomahawk and Raptor fields and
     expects first  production from these fields in the second half of 2004. The
     Company also expects to complete its other  significant  United States Gulf
     of Mexico  development  projects,  Harrier and Devils  Tower,  in early and
     mid-2004, respectively.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 2003
                                   (Unaudited)


o    Commodity market supply and demand fundamentals have continued to stabilize
     during the quarter as evidenced by quoted  futures prices that suggest that
     North  American gas prices will remain  relatively  flat over the next five
     years and that  worldwide  oil prices may decline  modestly  over that time
     span compared to relatively high current levels for each commodity.

o    The Company's future revenues are further  protected against price declines
     through its significant hedging program. The Company has hedged portions of
     its oil price risk  through 2005 and portions of its gas price risk through
     2007. See Note E for information regarding the Company's hedge positions.

o    The Company has  generated  record  pretax  income for the third quarter of
     2003,  significant  net income for the nine months ended September 30, 2003
     and net income in each of the years ended December 31, 2002, 2001 and 2000.
     The Company has also  generated  significant  taxable  income for the third
     consecutive  quarter,  including  the  deduction  of  100  percent  of  its
     intangible  drilling  costs for those  periods.  The Company  believes that
     these trends will continue for the foreseeable future.

o    The Company performed various economic  evaluations in the third quarter to
     determine  if the Company  would be able to realize all of its deferred tax
     assets,  including  its net  operating  loss  carryforwards,  prior  to any
     expiration.   These   evaluations  were  based  on  the  Company's  reserve
     projections of existing  producing  properties and recent discoveries being
     developed.  These evaluations  employed varying price assumptions,  some of
     which included a significant reduction in commodity prices, and factored in
     limitations on the use of the Company's net operating  loss  carryforwards.
     The evaluations did not include assumptions of increases in proved reserves
     through future exploration or acquisitions.  The evaluations indicated that
     the deferred tax assets are realizable in the future.

       Accordingly,  during the third quarter of 2003,  the Company reversed its
valuation  allowance in the United  States,  resulting in the  recognition  of a
deferred tax benefit of $104.7 million ($.88 per diluted  share).  Further,  the
reversal of the allowance increased stockholders' equity by $32.6 million as the
Company  recognized  the tax  effects of previous  stock  option  exercises  and
deferred hedging gains and losses in other comprehensive income.

       Pioneer will continue to  monitor Company-specific,  oil and gas industry
and  worldwide  economic  factors  and will  reassess  the  likelihood  that the
Company's net operating  loss  carryforwards  and other  deferred tax attributes
will be utilized  prior to their  expiration.  There can be no  assurances  that
facts and  circumstances  will not materially  change and require the Company to
reestablish a United States deferred tax asset  valuation  allowance in a future
period.  As of  September  30,  2003,  the  Company  does not  believe  there is
sufficient  positive  evidence to reverse its  valuation  allowances  related to
certain foreign tax jurisdictions. The Company's valuation allowances related to
foreign tax jurisdictions are $53.4 million as of September 30, 2003.

       Income tax  (provision)  benefit  attributable  to income  (loss)  before
cumulative  effect of change in accounting  principle  consists of the following
for the three and nine month periods ended September 30, 2003 and 2002:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE D.     Asset Acquisition

       On March 28, 2003, the Company purchased the remaining 25 percent working
interest that it did not already own in the Falcon field,  the Harrier field and
surrounding  satellite  prospects  in the  deepwater  Gulf of Mexico  for $119.4
million,  including  $113.1  million of cash paid upon closing,  $1.7 million of
asset retirement obligations assumed and $4.6 million of closing adjustments.

NOTE E.     Derivative Financial Instruments

       Fair value hedges.  The Company  monitors the  debt  capital  markets and
interest  rate  trends to  identify  opportunities  to enter into and  terminate
interest rate swap contracts with the objective of minimizing  costs of capital.
During  August and February  2003,  the Company  entered into interest rate swap
contracts  to hedge a  portion  of the fair  value of its 9-5/8  percent  senior
notes.  Under the terms of the interest rate swap contracts  entered into during
August 2003 (the "August Contracts"),  the Company contracted to receive a fixed
annual rate of 9-5/8 percent on $300.0 million notional amount and agreed to pay
the counterparties a variable rate on the notional amount equal to the six-month
LIBOR, reset  semi-annually,  plus a weighted average margin ("LIBOR Margin") of
521.0 basis points.  The terms of the interest rate swap contracts  entered into
during  February  2003 (the  "February  Contracts")  differed  from those of the
August  Contracts  only in notional  amount and LIBOR  Margin,  which terms were
$250.0 million and 566.4 basis points, respectively.  During September 2003, the
Company terminated the August Contracts for $10.1 million of cash proceeds.  The
cash proceeds were comprised of $1.2 million of settlement gains attributable to
the period from August 2003  through the date of  termination  and $8.9  million
attributable  to the fair value,  on the date of  termination,  of the remaining
term of the  August  Contracts.  During May 2003,  the  Company  terminated  the
February  Contracts for $11.4 million of cash  proceeds.  The cash proceeds were
comprised of $2.0 million of settlement  gains  attributable  to the period from
February 2003 through the date of termination  and $9.4 million  attributable to
the  fair  value,  on the  date of  termination,  of the  remaining  term of the
February Contracts.  The $8.9 million and $9.4 million of proceeds  attributable
to the fair value of the  remaining  term of the August  Contracts  and February
Contracts  are  included  in  "Proceeds  from  disposition  of  assets"  in  the
accompanying  Consolidated  Statements of Cash Flows during the periods that the
hedges were terminated.

       As of September 30,  2003,  the carrying value of the Company's long-term
debt in the accompanying  Consolidated  Balance Sheets included $34.7 million of
incremental  carrying value attributable to unamortized net deferred hedge gains
realized from  terminated  fair value hedge  interest rate swap  contracts.  The
amortization of net deferred hedge gains reduced the Company's reported interest
expense by $6.3 million and $2.3 million  during the three month  periods  ended
September 30, 2003 and 2002, respectively, and by $18.1 million and $7.9 million
during the nine month periods ended September 30, 2003 and 2002, respectively.

       The following table sets forth the scheduled amortization of net deferred
hedge gains and losses on terminated  fair value hedges as of September 30, 2003
that will be recognized as increases,  in the case of losses,  or decreases,  in
the case of gains, to the Company's future interest expense:

      The terms of the  fair value hedges described  above perfectly matched the
terms of the underlying senior notes.  The Company did not exclude any component
of the derivatives' gains or losses from the measurement of hedge effectiveness.

       Cash  flow  hedges.  The  Company  utilizes  commodity  swap  and  collar
contracts to (i) reduce the effect of price  volatility on the  commodities  the
Company produces and sells,  (ii) support the Company's annual capital budgeting
and  expenditure  plans and (iii) reduce  commodity  price risk  associated with
certain  capital  projects.  The Company has also  utilized  interest  rate swap
agreements  to reduce the effect of interest  rate  volatility  on the Company's
variable  rate  line  of  credit  indebtedness  and  forward  currency  exchange
agreements to reduce the effect of U.S.  dollar to Canadian dollar exchange rate
volatility.

       Oil.  All material sales contracts governing the Company's oil production
have been tied directly or indirectly to NYMEX prices.  The following table sets
forth the Company's  outstanding  oil hedge  contracts and the weighted  average
NYMEX prices for those contracts as of September 30, 2003:

        Natural gas  liquids prices.  During the  three and  nine month  periods
ended September 30, 2003 and 2002,  the Company did not enter into any NGL hedge
contracts.

       Gas prices.  The Company employs a policy of hedging a portion of its gas
production  based on the index  price upon which the gas is  actually  sold,  or
based on NYMEX  prices if NYMEX  prices  are  highly  correlated  with the index
prices,  in order to mitigate  the basis risk  between  NYMEX  prices and actual
index prices. The following table sets forth the Company's outstanding gas hedge
contracts  and the  weighted  average  index  prices for those  contracts  as of
September 30, 2003:

       Hedge ineffectiveness and excluded items.  During the three month periods
ended September 30, 2003 and 2002, the Company  recognized  other expense of $.3
million and $1.4 million,  respectively,  related to the ineffective portions of
its cash flow hedging instruments. During the nine month periods ended September
30, 2003 and 2002, the Company recognized other expense of $2.6 million and $1.7
million, respectively, related to the ineffective portion of its cash flow
hedging instruments.

       Accumulated other  comprehensive income (loss)  ("AOCI") -  net  deferred
hedge gains  (losses),  net of tax. As of  September  30, 2003 and  December 31,
2002,  "AOCI - net deferred hedge gains  (losses),  net of tax"  represented net
deferred  losses  of $55.0  million  and net  deferred  gains  of $9.6  million,
respectively. The "AOCI - net deferred hedge gains (losses), net of tax" balance
as of September 30, 2003 was comprised of $118.3 million of unrealized  deferred
hedge losses on the effective portions of open commodity cash flow hedges, $40.0
million of net deferred  gains on terminated  cash flow hedges and $23.3 million
of associated  net deferred tax  benefits.  The decrease in "AOCI - net deferred
hedge gains  (losses),  net of tax" during the nine months ended  September  30,
2003 was primarily attributable to increases in future commodity prices relative
to the  commodity  prices  stipulated  in the  hedge  agreements,  offset by the
reclassification  of net  deferred  hedge  losses to net  income as  derivatives
matured by their terms and the reversal of associated United States deferred tax
valuation allowances.  The unrealized net  deferred hedge losses associated with

open cash flow hedges  remain  subject to market  price  fluctuations  until the
positions  are  either  settled  under  the  terms of the  hedge  agreements  or
terminated  prior to settlement.  The net deferred gains on terminated cash flow
hedges are fixed.

       During the twelve months ending September 30,  2004,  the Company expects
to reclassify  $75.1 million of net deferred  losses  associated  with open cash
flow hedges,  $27.8 million of net deferred gains on terminated cash flow hedges
and  approximately  $16.6  million of net deferred tax benefits from "AOCI - net

NOTE F.     Asset Retirement Obligations

       As referred to in Note B,  the Company adopted the provisions of SFAS 143
on January 1, 2003. The Company's asset retirement  obligations primarily relate
to the  future  plugging  and  abandonment  of  proved  properties  and  related
facilities.  The Company has no assets that are legally  restricted for purposes
of settling asset  retirement  obligations.  The following table  summarizes the
Company's asset retirement  obligation  transactions recorded in accordance with
the  provisions  of SFAS 143  during  the three  and nine  month  periods  ended

effect on the Company's  consolidated  financial  position,  liquidity,  capital
resources or future results of operations. The Company will continue to evaluate
its  litigation  matters  on a  quarter-by-quarter  basis  and will  adjust  its
litigation  reserves  as  appropriate  to  reflect  the then  current  status of
litigation.

       Alford.  The Company is party to a 1993 class action lawsuit filed in the
26th Judicial District Court of Stevens County, Kansas by two classes of royalty
owners,  one for  each  of the  Company's  gathering  systems  connected  to the
Company's Satanta gas plant. The case was relatively inactive for several years.
In early 2000, the plaintiffs  amended their  pleadings to add claims  regarding
the field  compression  installed by the Company in the 1990's.  The lawsuit now
has two material claims.  First, the plaintiffs assert that the expenses related
to the field  compression are a "cost of production" for which plaintiffs cannot
be charged their  proportionate  share under the  applicable oil and gas leases.
Second,  the  plaintiffs  claim they are entitled to 100 percent of the value of
the helium extracted at the Company's  Satanta gas plant. If the plaintiffs were
to prevail on the above two claims in their  entirety,  it is possible  that the
Company's  liability  could  reach $33.8  million,  plus  prejudgment  interest.
However,  the Company believes it has valid defenses to the plaintiffs'  claims,
has paid the plaintiffs  properly under their respective oil and gas leases, and
intends to vigorously defend itself.

       The Company believes the cost  of the field compression is not a "cost of
production",  but is rather an expense of transporting  the gas to the Company's
Satanta gas plant for processing,  where valuable hydrocarbon liquids and helium
are extracted from the gas. The plaintiffs benefit from such extractions and the
Company believes that charging the plaintiffs with their  proportionate share of
such  transportation and processing  expenses is consistent with Kansas law. The
Company has also vigorously  defended against  plaintiffs' claims to 100 percent
of the value of the helium  extracted,  and  believes  that in  accordance  with
applicable law, it has properly accounted to the plaintiffs for their fractional
royalty  share  of  the  helium  under  the  specified  royalty  clauses  of the
respective oil and gas leases.

       The factual  evidence in  the case  was presented  to the  26th  Judicial
District Court without a jury in December 2001. Oral arguments were heard by the
court in April 2002,  and  although  the court has not yet entered a judgment or
findings,  it could do so at any time. The Company strongly denies the existence
of any material  underpayment to the plaintiffs and believes it presented strong
evidence at trial to support its  positions.  The Company has not yet determined
the amount of damages, if any, that would be payable if the Court were to render
an adverse judgement  against the Company.  Although the amount of any resulting
liability  could  have a material  adverse  effect on the  Company's  results of
operations  for the  quarterly  reporting  period  in which  such  liability  is
recorded,  the  Company  does not  expect  that any such  liability  will have a
material adverse effect on its consolidated  financial position as a whole or on
its liquidity, capital resources or future annual results of operations.

       Kansas ad valorem tax. The Natural Gas Policy Act of 1978 ("NGPA") allows
a "severance,  production or similar" tax to be included as an add-on,  over and
above the maximum  lawful price for gas.  Based on a Federal  Energy  Regulatory
Commission ("FERC") ruling that Kansas ad valorem tax was such a tax, one of the
Company's  predecessor  entities collected the Kansas ad valorem tax in addition
to the otherwise  maximum  lawful  price.  The FERC's ruling was appealed to the
United  States Court of Appeals for the District of Columbia  ("D.C.  Circuit"),
which held in June 1988 that the FERC failed to provide a  reasonable  basis for
its findings and remanded the case to the FERC for further consideration.

       On December 1, 1993, the FERC issued an order reversing its prior ruling,
but limited the effect of its decision to Kansas ad valorem taxes for sales made
on or after June 28, 1988. The FERC clarified the effective date of its decision
by an order dated May 18, 1994.  The order  clarified  that the  effective  date
applies to tax bills  rendered  after June 28, 1988,  not sales made on or after
that date.  Numerous  parties  filed  appeals  on the FERC's  action in the D.C.
Circuit.  Various gas producers challenged the FERC's orders on two grounds: (1)
that  the  Kansas  ad  valorem  tax,  properly  understood,   does  qualify  for
reimbursement  under the NGPA; and (2) the FERC's ruling  should,  in any event,
have been applied  prospectively.  Other parties challenged the FERC's orders on
the grounds that the FERC's  ruling  should have been applied  retroactively  to
December 1, 1978,  the date of the  enactment of the NGPA and  producers  should
have been required to pay refunds accordingly.

       The D.C. Circuit issued its decision on August 2, 1996,  which holds that
producers  must make refunds of all Kansas ad valorem tax collected with respect
to production since October 4, 1983, as opposed to June 28, 1988.  Petitions for
rehearing  were denied on November 6, 1996.  Various gas producers  subsequently
filed a petition  for writ of  certiori  with the United  States  Supreme  Court
seeking to limit the scope of the potential  refunds to tax bills rendered on or
after  June 28,  1988 (the  effective  date  originally  selected  by the FERC).
Williams  Natural Gas Company  filed a  cross-petition  for certiori  seeking to
impose refund  liability back to December 1, 1978. Both petitions were denied on
May 12, 1997.

       The Company and  other producers  filed petitions for adjustment with the
FERC on June 24,  1997.  The Company  was seeking a waiver or set-off  from FERC
with respect to that portion of the refund  associated  with (i)  non-recoupable
royalties,  (ii)  non-recoupable  Kansas property taxes based, in part, upon the
higher  prices  collected and (iii)  interest for all periods.  On September 10,
1997,  FERC denied this request,  and on October 10, 1997, the Company and other
producers filed a request for rehearing. Pipelines were given until November 10,
1997 to file claims on refunds sought from producers and refund claims  totaling
approximately $30.2 million were made against the Company. Through September 30,
2003, the Company has settled $21.7 million of the original claim amounts. As of
September  30, 2003 and  December  31,  2002,  the Company had on deposit  $10.5
million and $10.6  million,  respectively,  including  accrued  interest,  in an
escrow  account  and  had  corresponding  obligations  for the  remaining  claim
recorded in other current liabilities in the accompanying  Consolidated  Balance
Sheets.  The Company believes that the escrowed amounts,  plus accrued interest,
will be sufficient to settle the remaining claims.

NOTE H.     Income (Loss) Per Share Before Cumulative Effect of Change in
            Accounting Principle

       Basic  income  (loss) per  share before  cumulative  effect of  change in
accounting  principle is computed by dividing  income (loss)  before  cumulative
effect of change in  accounting  principle  by the  weighted  average  number of
common shares  outstanding for the period. The computation of diluted income per
share before  cumulative effect of change in accounting  principle  reflects the
potential  dilution that could occur if  securities or other  contracts to issue
common stock that are dilutive to income before  cumulative  effect of change in
accounting  principle  were exercised or converted into common stock or resulted
in the  issuance  of common  stock that would then share in the  earnings of the
Company.

       The following table is a reconciliation of the basic and diluted weighted
average common  shares outstanding during the three and nine month periods ended
September 30, 2003 and 2002:

     principle per share for the three month  periods  ended  September 30, 2003
     and 2002,  respectively,  and common  stock  options to purchase  1,308,582

     included in the computations of diluted income before  cumulative effect of
     change in  accounting  principle per share for the nine month periods ended
     September 30, 2003 and 2002,  respectively,  because the exercise prices of
     the options were greater than the average market price of the common shares
     and would have been anti-dilutive to the computations. In-the-money options
     representing  1,932,385  weighted average equivalent shares of common stock
     and 395 weighted  average  equivalent  shares of unvested  restricted stock
     were not included in the computation of diluted net loss before  cumulative
     effect of change in  accounting  principle for the three month period ended
     September  30,  2002,  since they have a dilutive  effect to that  period's
     loss.

NOTE I.     Geographic Operating Segment Information

       The Company has operations in  only one industry segment,  that being the
oil and gas  exploration  and  production  industry;  however,  the  Company  is
organizationally structured along geographic operating segments, or regions. The
Company has reportable operations in the United States, Argentina and Canada.

       The following tables provide the  Company's interim  geographic operating
segment data for the three and nine month periods  ended  September 30, 2003 and
2002.  Geographic  operating segment income tax benefits  (provisions) have been
determined  based on statutory  rates existing in the various tax  jurisdictions
where the Company has oil and gas producing  activities.  The  "Headquarters and
Other" column includes revenues and expenses that are not routinely  included in
the  earnings  measures  internally  reported  to  management  on  a  geographic
operating segment basis.

Item 2.    Management's Discussion and Analysis of Financial Condition and
           Results of Operations

       The information  included in  Item 2 and Item 3 of this document includes
forward-looking  statements that are made pursuant to the Safe Harbor Provisions
of  the  Private  Securities  Litigation  Reform  Act of  1995.  Forward-looking
statements, and the business prospects of Pioneer Natural Resources Company (the
"Company"  or  "Pioneer"),  are  subject to a number of risks and  uncertainties
which  may cause the  Company's  actual  results  in  future  periods  to differ
materially from the  forward-looking  statements.  These risks and uncertainties
include,  among other things,  volatility of oil and gas prices,  product supply
and demand,  competition,  international operations and associated international
political and economic instability, government regulation or action, litigation,
the costs and results of  drilling  and  operations,  the  Company's  ability to
replace  reserves,  implement  its business  plans or complete  its  development
projects  as  scheduled,  access  to and cost of  capital,  uncertainties  about
estimates of  reserves,  quality of technical  data,  environmental  and weather
risks,  acts of war and  terrorism.  These and other risks are  described in the

Financial and Operating Performance

       The Company's financial  and operating  performance for the third quarter
of 2003 was highlighted by strong  production from the Company's  deepwater Gulf
of Mexico Canyon Express and the Company-operated  Falcon field gas projects and
increased  oil and gas  sales  in  Argentina.  Argentine  oil  drilling  results
exceeded expectations while a strengthening Argentine economy boosted gas sales.
The production growth achieved by the Company, together with favorable worldwide
oil and North American gas prices, has resulted in significant  increases in the
Company's  net income and net cash provided by operating  activities  during the
three and nine month periods  ended  September 30, 2003, as compared to the same
respective periods of 2002.

       The Company  reported net  income of  $191.8 million  ($1.62 per  diluted
share) and $353.2 million ($2.99 per diluted share) for the three and nine month
periods  ended  September 30, 2003,  respectively,  as compared to a net loss of
$890 thousand  ($.01 per diluted share) and net income of $8.3 million ($.07 per
diluted share) for the same respective periods of 2002. The Company's net income
for the nine months ended  September 30, 2003 includes a $15.4 million ($.13 per
share) benefit from the cumulative effect of change in accounting principle, net
of tax,  associated  with the  Company's  adoption  of  Statement  of  Financial
Accounting  Standards No. 143,  "Accounting  for Asset  Retirement  Obligations"
("SFAS  143") on  January 1,  2003.  See Notes B and F of Notes to  Consolidated
Financial  Statements included in "Item 1. Financial  Statements" for additional
information  regarding the Company's adoption of new accounting  pronouncements.
Net income for the three and nine month  periods  ended  September  30, 2003 was
also positively impacted by the reversal of the Company's United States deferred
tax asset valuation allowances. See "Results of Operations - Income tax benefits
(provisions)"  for  information  regarding  the  reversal  of the United  States
deferred tax asset valuation allowances.

       The  Company's  net cash  provided by  operating  activities  was  $222.5
million and $546.7 million for the three and nine month periods ended  September
30,  2003,  respectively,  representing  increases  of  $134.8  million,  or 154
percent,  and $318.4  million,  or 140  percent,  over the net cash  provided by
operating  activities of the same respective  periods of 2002. Net cash provided
by operating  activities during the three and nine month periods ended September
30, 2002 was $87.7 million and $228.3  million,  respectively.  During the three
months  ended  September  30, 2003,  the Company  used its net cash  provided by
operating activities,  together with proceeds from the disposition of assets, to
fund $134.9  million of additions to oil and gas  properties  and to repay $92.0
million of long-term debt.  During the nine months ended September 30, 2003, the
Company  used its net cash  provided  by  operating  activities,  together  with
proceeds from the disposition of assets,  to fund $522.0 million of additions to
oil and gas properties and to repay $47.5 million of long-term debt.

Drilling Highlights

        During the  first nine  months of  2003,  the  Company  incurred  $531.8
million  in  capital  expenditures  including  $207.3  million  for  development
activities,  $192.7  million for  exploration  activities  and $131.8 million on
acquisitions.   The  majority  of  the  Company's  development  and  exploration
expenditures was spent on drilling wells,  seismic data and  infrastructure  for
the Company's  significant  development  projects.  The primary component of the

acquisition  expenditures  was the Company's  purchase of the 25 percent working
interest  it did not  already own in the Falcon  field,  the  Harrier  field and
surrounding   satellite  prospects  during  March  2003.  The  following  tables
summarize  the  Company's  development  drilling and  exploration  and extension
drilling activities for the nine months ended September 30, 2003:

       Domestic.  The Company spent $405.1 million  during the first nine months
of  2003  on  acquisition,  drilling  and  seismic  activities  in the  Gulf  of
Mexico/Gulf Coast,  Alaska,  Permian Basin and Mid-Continent areas of the United
States.

       Gulf of Mexico/Gulf  Coast area.  In the Gulf of  Mexico/Gulf Coast area,
the Company spent $278.4 million of acquisition,  drilling and seismic  capital.
In the  deepwater  Gulf of  Mexico,  the  Company  completed  its  Falcon  field
development  in  mid-March  2003 and, as  previously  discussed,  purchased  the
remaining 25 percent working  interest in Falcon and related  prospects that the
Company did not already own. The Company has two major development projects that
remain in progress as of September 30, 2003:

o    Devils Tower - The  Dominion-operated  Devils Tower development  project in
     Mississippi  Canyon was  sanctioned in 2001 as a spar  development  project
     with the  owners  leasing  a spar  from a third  party  for the life of the
     field.  The  hull  of  the  spar  was  constructed  in  Indonesia  and  was
     successfully  transported  to the United States during the first quarter of
     2003 where the topsides  will be added  during the fourth  quarter of 2003.
     The spar has slots for eight dry tree wells and up to three subsea tie-back
     wells and is capable of handling 60 MBbls of oil per day and 60 MMcf of gas
     per day.  Eight Devils Tower wells and one subsea  tie-back  well have been
     drilled and are awaiting  completion.  Devils Tower production is scheduled
     to begin in the  second  quarter of 2004 and will be phased in as the wells
     are  individually  completed  from the spar. The Company also plans to spud
     its satellite  Goldfinger  prospect and participate in an appraisal well on
     the Triton prospect during the fourth quarter of 2003. If successful, these
     wells  could be the second and third  subsea  tie-back  wells.  The Company
     holds a 25 percent working interest in these projects.

o    Harrier/Tomahawk/Raptor  - The Company  discovered the Harrier field during
     the first  quarter of 2003 and the  Tomahawk and Raptor  fields  during the
     third quarter of 2003.  The Company operates  the blocks with a 100 percent

                                       25




                        PIONEER NATURAL RESOURCES COMPANY


     working  interest  subsequent to the acquisition  discussed  above,  and is
     developing all three fields as single- well subsea  tie-backs to the Falcon
     field facilities which were designed to be expandable.  To accommodate this
     incremental  production and potential throughput associated with additional
     planned exploration,  an additional parallel pipeline connecting the Falcon
     field to the Falcon  platform on the Gulf of Mexico  shelf is being  added,
     doubling its capacity to 400 MMcf of gas per day. The Company expects first
     gas production from the Harrier field in early 2004 with combined daily gas
     production  from the Falcon field and the Harrier  field  expected to reach
     275 MMcf per day. In addition,  the Company  expects  first gas  production
     from the  Tomahawk and Raptor  fields in the third  quarter of 2004 thereby
     approaching full capacity on the Falcon subsea systems.

       The Company plans to  spud a well on the BP-operated Juno prospect in the
Mississippi  Canyon  area in early  November  2003.  The Juno  well  will test a
high-potential deep structure. The Company owns a 25 percent working interest in
this prospect.  In addition to the development  projects  described above in the
deepwater Gulf of Mexico,  the Company  drilled two exploratory dry holes in the
Falcon area during the first quarter. The Company controls 32 blocks in the area
providing numerous  exploration  opportunities for future subsea tiebacks to the
Falcon systems.

       During January 2003,  the Company announced a joint exploration agreement
with Woodside Energy (USA), Inc.  ("Woodside"),  a subsidiary of Woodside Energy
Ltd. of Australia,  for a two-year drilling program over the shallow-water Texas
shelf region of the Gulf of Mexico. Under the agreement, Woodside has taken a 50
percent  working  interest in 47  offshore  exploration  blocks  operated by the
Company.  The  agreement  covers eight  prospects and 19 leads and includes five
exploratory  wells to be drilled in 2003 and three in 2004. Most of the wells to
be drilled  under the  agreement  will target gas plays below 15,000  feet.  The
eight  wells to be  drilled  by the  parties  in 2003 and 2004 are on  prospects
generated and leased by the Company since 1997. The first three wells under this
joint  agreement  were  unsuccessful.  The fourth  well is in  progress  and the
results are expected to be known in December 2003. Additionally, the Company and
Woodside  will  evaluate  shallower gas prospects on the Gulf of Mexico shelf on
other  blocks  covered by the leases for  potential  inclusion  in the  drilling
program.

       In the onshore  Gulf Coast region of  the United States,  the Company has
concentrated  its drilling  efforts in the Pawnee  field in South  Texas,  where
three  development  wells and one  extension  well were  successfully  completed
during the first nine months of 2003.  The Company  plans to drill an additional
four development wells and two extension wells during the remainder of 2003.

       Alaska.  In Alaska, the Company spent $34.1 million during the first nine
months of 2003 to drill three  exploration  wells on the NW Kuparuk  prospect to
test a possible  extension of the  productive  sands in the Kuparuk  River field
into the  shallow  waters  offshore.  Although  all three of the wells found the
sands filled with oil, they were too thin to be considered commercial. The wells
also encountered  thick sections of oil-bearing  Jurassic-aged  sands. The first
well flowed at a sustained rate of approximately 1,300 barrels per day. The test
results are currently being  evaluated to determine the commercial  viability of
the Jurassic reservoir.

       On the North  Slope of Alaska,  the Company  recently  participated  in a
state  lease  sale  and was the  apparent  high  bidder  on 53  tracts  covering
approximately  150,000  acres,  establishing  a  leasehold  over  a  variety  of
prospects.

       Permian Basin area.  In the Permian Basin area,  the Company  spent $49.6
million during the first nine months of 2003  primarily on development  drilling
in the Spraberry  field. The Company plans to drill  approximately  140 wells in
the  Spraberry  field  during  2003.  The  Company  has drilled 114 wells in the
Permian Basin area during the nine months ended September 30, 2003, 103 of which
were drilled in the Spraberry field.

       Mid-Continent area.  In the Mid-Continent area,  the Company  spent $43.0
million  during the first nine months of 2003,  primarily in the West  Panhandle
field where the Company plans to drill  approximately  100 wells this year.  The
Company plans to drill approximately 20 Hugoton wells this year. During the nine
months ended September 30, 2003, the Company has drilled 79 West Panhandle field
wells and 19 Hugoton wells.

       Argentina.  In Argentina, the Company spent $36.7 million of acquisition,
drilling and seismic  capital during the first nine months of 2003. The majority
of costs  was spent to drill  extension  and  development  wells  targeting  oil
reserves in the Neuquen Basin.

                        PIONEER NATURAL RESOURCES COMPANY


       Canada.  In  Canada,  the  Company  spent  $41.2  million of acquisition,
drilling and seismic capital during the first nine months of 2003,  primarily in
the  Chinchaga,  Martin Creek and Ladyfern  areas that are only  accessible  for
drilling during the winter months.  The Company tested several shallow gas plays
finding multiple  gas-bearing zones based on open-hole logs and mud log shows in
several  wells.  However,  unseasonably  warm  weather  resulted in a very short
drilling  season in Canada,  and  approximately  eight of the wells drilled will
have to be tested during next year's winter  drilling  season.  Three wells were
drilled to test the Slave Point  formation in the Ladyfern  field area. One well
was  unsuccessful,  and two wells were unsuccessful in the Slave Point formation
but are being evaluated for uphole potential in another formation.

       Africa.  In  Africa,  the  Company  spent  $48.8  million of acquisition,
drilling  and  seismic  capital  during the first  nine  months of 2003 in South
Africa, Tunisia and Gabon.

       South Africa. In South Africa, the Company spent $32.8 million of capital
to drill three exploratory wells and to continue  development of its Sable field
that began  production  during  August  2003.  First sales of Sable oil occurred
during  October 2003.  During the second  quarter of 2003,  the Company  drilled
three  2003  planned  exploratory  wells in  South  Africa,  none of which  were
commercial.

       Tunisia.  In Tunisia,  the Company spent  $14.0 million of capital during
the first nine months of 2003. The Company drilled two exploration  wells on the
Anadarko-operated  Anaguid  permit during the second  quarter of 2003. The CEM-1
encountered  95  feet  of  net  gas  and  condensate  pay  in  upper  Ordovician
sandstones.  In a drill stem test,  the  unstimulated  well  flowed at a rate of
3,600 Mcf per day and 540 Bbls per day. A second well, the SEA-1, encountered 52
feet of net pay in the same section.  Both wells have been suspended pending the
evaluation of commercial development plans.

       On  the  Borj  El  Khadra  permit,   the  Company  completed  development
activities on the Adam 1 discovery  well and began  production in late May 2003.
The well has been  producing at a gross  stabilized  rate of over 3,500 Bbls per
day with first sales  occurring  during the third  quarter of 2003.  The Company
participated  in the successful Adam 2 development  well, the first  development
well in the 860  square  kilometer  Adam  concession.  The  Company  also  began
drilling  the  Hawa  exploration  well  in the  southern  portion  of  the  Adam
concession  and  results are  expected  during the fourth  quarter of 2003.  The
Company  has a 28 percent  interest in the Adam  concession.  In  addition,  the
Company  drilled an  unsuccessful  exploration  well on the Jorf permit early in
2003.

       Gabon.  In Gabon,  the Company  spent $2.0 million  during the first nine
months of 2003. The Company has received  ministerial  approval for the improved
terms  negotiated  for the Olowi permit,  in which the Company has a 100 percent
working interest. The Company plans to commence a multi-well drilling program in
early 2004 to further define the scale of a development plan, initially focusing
on the Lower Gamba.  The Company has begun to solicit interest from possible new
partners in the project.

Results of Operations

       Oil and gas revenues. Revenues from oil and gas operations totaled $332.5
million and $953.6 million for the three and nine month periods ended  September
30, 2003,  respectively,  compared to $168.3  million and $506.3 million for the
same respective periods of 2002. The increase in oil and gas revenues during the
three and nine month periods  ended  September 30, 2003, as compared to the same
respective  periods of 2002, was  principally  attributable  to incremental  gas
sales from the  Company's  deepwater  Gulf of Mexico  Canyon  Express and Falcon
field  projects,  increased oil and gas sales in Argentina  and commodity  price
increases. As expected, declines in Canadian production partially offset the
above described increases to oil and gas revenues.

       On a BOE  basis,  worldwide  average  daily  production  increased  by 40
percent and 34 percent  during the three and nine month periods ended  September
30,  2003,  respectively,  as compared to the same  respective  periods of 2002.
During  the third  quarter  of 2003 as  compared  to the third  quarter of 2002,
worldwide  oil  production  increased  by 13 percent,  NGL  production  remained
virtually unchanged and gas production, augmented by incremental production from
both the Canyon Express and Falcon field gas projects,  increased by 67 percent.
During the first nine  months of 2003,  as  compared to the first nine months of
2002,  worldwide  oil  production  increased by three  percent,  NGL  production
increased  by two  percent  and gas  production,  augmented  by nine  months  of
production from Canyon Express and production since March from the Falcon field,
increased by 63 percent.  Per BOE average daily production,  on a third- quarter
to third-quarter comparison, increased by 54 percent in the United States and by
15 percent in Argentina,  while  production  in Canada  decreased by 16 percent.
During the first nine  months of 2003 as  compared  to the first nine  months of
2002,  per BOE average  daily  production  increased by 45 percent in the United
States and by 13 percent in Argentina,  while  production in Canada decreased by
14 percent.

       Fourth quarter  2003 production is expected to average 150,000 to 165,000
BOE per day.  During the fourth  quarter,  the  Company  expects the first cargo
sales for oil produced  into storage in both South Africa and Tunisia.  However,
due to uncertainty regarding the timing of cargos, total sales during the fourth
quarter are difficult to predict.  In South Africa,  volume estimates  reflect a
slower  ramp-up  of Sable  field  production  due to  mechanical  problems  with
compression equipment.

       As in past years,  Argentine gas sales are expected to be impacted by the
seasonal decline in gas demand as Argentina  enters their summer season.  Fourth
quarter  gas sales  will also be  impacted,  as  expected,  by a one to two week
shut-in of the Falcon field in order to tie in the Harrier  satellite  discovery
for first production in early 2004.

                        PIONEER NATURAL RESOURCES COMPANY


       As previously  discussed,  oil and gas  revenues for  the  three and nine
month periods ended  September  30, 2003 were  positively  impacted by commodity
price  increases.  Comparing  the third  quarter of 2003 to the same  respective
period in 2002, the Company's  average worldwide oil price increased 16 percent,
average  worldwide  NGL prices  increased 33 percent and average  worldwide  gas
prices increased 62 percent. Comparing the first nine months of 2003 to the same
respective  period in 2002, the Company's  average worldwide oil price increased
10  percent,  average  worldwide  NGL prices  increased  48 percent  and average
worldwide gas prices increased 64 percent.

       Hedging activities.  The oil and gas prices  that the Company reports are
based on the market price received for the  commodities  adjusted by the results
of the Company's cash flow hedging  activities.  The Company utilizes  commodity
derivative  instruments  (swap and collar  contracts) in order to (i) reduce the
effect  of the  volatility  of price  changes  on the  commodities  the  Company
produces and sells,  (ii) support the  Company's  annual  capital  budgeting and
expenditure  plans and (iii) reduce commodity price risk associated with certain
capital  projects.  During the three and nine month periods ended  September 30,
2003,  the Company's  commodity  price hedges  decreased oil and gas revenues by
$28.0 million and $100.9  million,  respectively,  as compared to decreasing oil
and gas  revenues by $1.4 million and  increasing  oil and gas revenues by $34.5
million  during  the same  respective  periods  in 2002.  See Note E of Notes to
Consolidated Financial Statements included in "Item 1. Financial Statements" for
specific information regarding the Company's hedging activities during the three
and nine month periods ended September 30, 2003 and 2002.

       During October 2003, the Company entered into new swap contracts to hedge
6,315 Bbls per day of fourth quarter 2003 oil sales at a weighted  average fixed
price per Bbl of  $31.51,  4,227  Bbls per day of 2004 oil  sales at a  weighted
average fixed price per Bbl of $29.20, 4,000 Bbls per day of 2008 oil sales at a
fixed  price per Bbl of  $26.05  and  20,000  Mcf per day of 2004 gas sales at a
weighted  average  fixed  price  per Mcf of  $4.96.  Additionally,  the  Company
terminated  its  collar  contracts  that  hedged  20,000 Mcf per day of 2004 gas
sales.

       Interest and other revenues. Interest and other revenues during the three
and nine month periods  ended  September 30, 2003 totaled $348 thousand and $4.3
million,  respectively,  as compared to $7.1 million and $9.1 million during the
same respective periods in 2002.

       Gain on disposition of assets.  During the  three and nine  month periods
ended  September 30, 2003,  the Company  recorded $46 thousand and $1.6 million,
respectively,  of net gains on the  disposition  of assets,  as compared to $3.4
million  and $4.4  million,  respectively,  of net gains on the  disposition  of
assets  during the same  respective  periods in 2002.  See "Capital  resources -
Sales of assets" for  additional  information  regarding  proceeds from sales of
assets.

       Oil and gas  production costs.  During the  three and n ine month periods
ended  September 30, 2003,  total  production  costs per BOE averaged  $4.78 and
$5.00,  respectively,  representing  an increase of $.12 per BOE (three percent)
and an  increase  of $.08 per BOE (two  percent),  respectively,  as compared to
total  production  costs per BOE of $4.66 and $4.92  during the same  respective
periods of 2002. Lease operating  expenses and workover  expenses  represent the
components of  production  costs for which the Company has  management  control,
while  production  and ad valorem  taxes and field fuel  expenses  are  directly
related to commodity price changes.

       The increase  in production costs per  BOE during the  three months ended
September 30, 2003, as compared to the same  respective  period in 2002,  can be
attributed to an increase in lease operating and field fuel expenses,  partially
offset by lower production and ad valorem taxes and workover costs. The increase
in lease operating  expenses is primarily due to the  strengthening  of both the
Argentine  peso and the  Canadian  dollar,  while  the  increase  in field  fuel
expenses is the result of higher gas prices.  The decrease in per BOE production
and ad valorem taxes is primarily due to the incremental  production  associated
with Canyon Express and Falcon which are not subject to production or ad valorem
taxes.

       The increase in  production costs  per BOE  during the nine  months ended
September 30, 2003, as compared to the same  respective  period in 2002,  can be
attributed to an increase in field fuel and lease operating  expenses as well as
production taxes, partially offset by lower ad valorem taxes and workover costs.
The increase in field fuel expenses is the result of higher gas prices,  and the
increase in production taxes, while benefitting from incremental production from
Canyon Express and Falcon where there are no production  taxes,  still increased
due to higher commodity prices.

       Based on market-quoted commodity prices during October 2003,  the Company
expects fourth quarter 2003 production  costs to average $4.75 to $5.15 per BOE.
The  potential  increase  is  primarily  due to higher  per BOE lease  operating
expenses associated with forecasted Sable production and an increase in expected
workover costs.

       Depletion,  depreciation and  amortization expense.  The Company's  total
depletion, depreciation and amortization expense per BOE was $6.89 and $6.68 for
the three and nine month periods  ended  September  30, 2003,  respectively,  as
compared  to $5.11  and  $5.09  during  the  same  respective  periods  of 2002.
Depletion expense per BOE, the largest component of depletion,  depreciation and
amortization  expense,  was $6.73 and  $6.50 per BOE  during  the three and nine
month periods ended September 30, 2003,  respectively,  as compared to $4.91 and
$4.88 per BOE during the same  respective  periods of 2002.  The increase in per
BOE depletion expense is primarily due to increases in higher cost-basis
deepwater Gulf of Mexico production volumes.

       The Company  expects  fourth  quarter 2003  depletion,  depreciation  and
amortization  expense  to  average  $6.90 to  $7.30  per BOE.  The  increase  is
principally attributable to higher cost-basis Sable production volumes.

       Exploration, abandonments, geological and geophysical costs. Exploration,
abandonments,  geological  and  geophysical  costs were $24.5 million and $107.4
million  during the three and nine  month  periods  ended  September  30,  2003,
respectively,  as compared to $18.3  million and $57.3  million  during the same
respective   periods  in  2002.  The  increase  in  exploration,   abandonments,
geological  and  geophysical  costs  during  the  first  nine  months of 2003 as
compared  to the  first  nine  months  of 2002  is  primarily  due to  increased
exploration/extension  drilling in the Gulf of Mexico, South Africa,  Canada and
Tunisia and  increases in seismic  acquisitions  that will  contribute to future
exploration  activities.  During  the first  nine  months of 2003,  the  Company
completed  and  evaluated  84  exploration/extension  wells,  41 of  which  were
successfully  completed as  discoveries.  During the same  respective  period in
2002, the Company completed and evaluated 27 exploration/extension  wells, 20 of
which were successfully completed as discoveries.

expense  to be $20  million to $40  million,  dependent  largely on  exploratory
drilling results and expected seismic expenditures.

       General and administrative expense.  General and  administrative expenses
for the three and nine month periods ended September 30, 2003 were $15.2 million
and $44.3 million,  respectively, as compared to $12.5 million and $35.1 million
during the same  respective  periods in 2002.  The increases of $2.7 million and
$9.2 million in general and administrative  expense for the respective three and
nine month periods ended  September 30, 2003, as compared to the same respective
periods in 2002,  are  primarily  due to increases in  administrative  staff and
performance-related compensation costs.

       The Company  expects  fourth  quarter  2003  general  and  administrative
expense to be $14 million to $15 million.

       Accretion of discount on  asset retirement obligations.  During the three
and nine month periods ended September 30, 2003,  accretion of discount on asset
retirement  obligations  was $1.3 million and $3.7  million,  respectively.  The
provisions  of SFAS  143  require  that  the  accretion  of  discount  on  asset
retirement obligations be classified in the consolidated statement of operations
separate from interest expense.  Prior to 2003 and the adoption of SFAS 143, the
Company  classified  accretion of discount on asset retirement  obligations as a
component of interest expense.  The Company's  interest expense during the three
and nine month periods ended  September 30, 2002 included $622 thousand and $1.9
million,  respectively, of accretion of discount on asset retirement obligations
that was calculated  prior to the adoption of SFAS 143 based on asset retirement
obligations recorded in purchased business combinations.  See "Cumulative effect
of change in accounting  principle"  and Notes B and F of Notes to  Consolidated
Financial  Statements included in "Item 1. Financial  Statements" for additional
information regarding the Company's adoption of SFAS 143.

        The Company expects  fourth quarter 2003  accretion of discount on asset
retirement obligations to be approximately $1 million.

       Interest expense.  Interest expense  was $23.2 million  and $69.5 million
for the three and nine month periods ended September 30, 2003, respectively,  as
compared to $20.3 million and $71.4 million for the same  respective  periods in
2002.  The increase of $2.9 million (or 14 percent) in interest  expense for the
three months ended September 30, 2003, as compared to the same respective period
of 2002, is primarily  attributable  to a $4.3 million  decrease in  capitalized
interest  due to the  completion  of the Canyon  Express  gas project and Falcon
field development,  partially offset by an increase in recorded hedge gains. The
decrease  of $1.9  million (or three  percent) in interest  expense for the nine
months ended  September 30, 2003, as compared to the same  respective  period of
2002,  is primarily  attributable  to interest  savings from the  repayment of a
higher  yielding  capital cost  obligation and a portion of the Company's  9-5/8
percent  and 8-7/8  percent  senior  notes,  lower  underlying  market  rates of
interest,  a 12.5 basis point decrease on May 16, 2003 in the Eurodollar  margin
component of the interest rate specified in the Company's $575 million corporate
credit   facility  (the  "Credit   Facility"),   the   aforementioned   separate
classification of accretion of discount on asset retirement obligations,  and an
increase of $2.3 million in interest rate hedge gains.  Partially offsetting the
decreases  in interest  expense  components  described  above was a $6.0 million
decline  in  interest  capitalized  during  the first  nine  months of 2003,  as
compared to the same respective period in 2002.

       The  Company  expects  fourth  quarter  2003  interest  expense to be $21
million to $23 million.

       Other expenses. Other expenses for the three and nine month periods ended
September  30,  2003  were $1.4  million  and $12.2  million,  respectively,  as
compared to $21.6 million and $37.6 million for the same  respective  periods in
2002. The $20.2 million decrease in other expenses during the three months ended
September  30,  2003,  as compared  to the same  respective  period of 2002,  is
primarily  attributable  to a $19.5  million  loss  recognized  from  the  early
extinguishment  of higher  yielding  senior  notes in 2002.  The  $25.4  million
decrease in other  expense  during the nine months ended  September 30, 2003, as
compared to the same respective  period of 2002, is primarily  attributable to a
$22.3 million loss recognized from the early  extinguishment  of higher yielding
senior notes in 2002. See "Cumulative effect of change in accounting  principle"
presented  below  for  information   regarding  the   reclassification  of  2002
extraordinary losses on the early extinguishment of debt.

       Income tax benefits (provisions). During the three and nine month periods
ended  September 30, 2003, the Company  recognized  income tax benefits of $99.9
million and $95.0 million, respectively. During the three and nine month periods
ended September 30, 2002, the Company  recognized  income tax provisions of $2.2
million and $3.2 million, of which $2.1 million and $2.8 million,  respectively,
was  attributable to Argentine  taxable  income.  The income tax benefit for the
nine months ended September 30, 2003 excludes a $1.3 million Argentine provision
that is  associated  with the gain  recognized  from the adoption of SFAS 143 on
January  1, 2003 (see  "Cumulative  effect  of change in  accounting  principle"
presented below).

       Since 1998,  the Company has maintained a  valuation allowance  against a
portion of its deferred tax asset position in the United States.  As of December
31,  2002,  the  Company's  deferred tax  valuation  allowances  totaled  $247.0
million,  comprised of $204.3  million of United  States  deferred tax valuation
allowances and $42.7 million of international deferred tax valuation allowances.
Statement of Financial  Accounting  Standards  No. 109 requires that the Company
continually  assess both positive and negative  evidence to determine whether it
is more likely than not that the  deferred  tax assets can be realized  prior to
their expiration. In the third quarter of 2003, the Company concluded that it is
now more  likely  than not that it will  realize  its gross  deferred  tax asset
position  in the United  States  after  giving  consideration  to the  following
specific facts:

o    Over the past several  years,  the Company has been steadily  improving its
     portfolio of assets,  including  significant proved reserve discoveries and
     follow-up  development  projects  that have  recently  started to  produce.
     Specifically, Pioneer completed development activities and began production
     operations on its Canyon  Express gas project in September  2002 and on the
     Falcon  field in March 2003.  The  production  performance  to-date and the
     reservoir  data that has been  accumulated  through  September  30, 2003 on
     these  projects  provide  assurance  that these  projects  will recover the
     reserves as predicted.

o    During the three months ended  September  30, 2003,  the Company  announced
     additional  Falcon area  discoveries  in the Tomahawk and Raptor fields and
     expects first  production from these fields in the second half of 2004. The
     Company also expects to complete its other  significant  United States Gulf
     of Mexico  development  projects,  Harrier and Devils  Tower,  in early and
     mid-2004, respectively.

                                       32




                        PIONEER NATURAL RESOURCES COMPANY


o    Commodity market supply and demand fundamentals have continued to stabilize
     during the quarter as evidenced by quoted futures prices, that suggest that
     North  American gas prices will remain  relatively  flat over the next five
     years and that  worldwide  oil prices may decline  modestly  over that time
     span compared to relatively high current levels for each commodity.

o    The Company's future revenues are further  protected against price declines
     through its significant hedging program. The Company has hedged portions of
     its oil price risk  through 2005 and portions of its gas price risk through
     2007. See Note E of Notes to Consolidated  Financial Statements included in
     "Item 1.  Financial  Statements"  for  information  regarding the Company's
     hedge positions.

o    The Company has  generated  record  pretax  income for the third quarter of
     2003,  significant  net income for the nine months ended September 30, 2003
     and net income in each of the years ended December 31, 2002, 2001 and 2000.
     The Company has also  generated  significant  taxable  income for the third
     consecutive  quarter,  including  the  deduction  of  100  percent  of  its
     intangible  drilling  costs for those  periods.  The Company  believes that
     these trends will continue for the foreseeable future.

o    The Company performed various economic  evaluations in the third quarter to
     determine  if the Company  would be able to realize all of its deferred tax
     assets,  including  its net  operating  loss  carryforwards,  prior  to any
     expiration.   These   evaluations  were  based  on  the  Company's  reserve
     projections of existing  producing  properties and recent discoveries being
     developed.  These evaluations  employed varying price assumptions,  some of
     which  included a  significant  negative  change to commodity  prices,  and
     factored in  limitations  on the use of the Company's  net  operating  loss
     carryforwards.  The evaluations did not include assumptions of increases in
     proved reserves through future exploration or acquisitions. The evaluations
     indicated that the deferred tax assets are realizable in the future.

       Accordingly,  during the third quarter of 2003,  the Company reversed its
valuation  allowance in the United  States,  resulting in the  recognition  of a
deferred tax benefit of $104.7 million.  Further,  the reversal of the allowance
increased  stockholders'  equity by $32.6 million as the Company  recognized the
tax effects of previous  stock option  exercises and deferred  hedging gains and
losses in other comprehensive income.

       Pioneer will  continue to monitor  Company-specific, oil and gas industry
and  worldwide  economic  factors  and will  reassess  the  likelihood  that the
Company's net operating  loss  carryforwards  and other  deferred tax attributes
will be utilized  prior to their  expiration.  There can be no  assurances  that
facts and  circumstances  will not materially  change and require the Company to
reestablish a United States deferred tax asset  valuation  allowance in a future
period.  As of  September  30,  2003,  the  Company  does not  believe  there is
sufficient  positive  evidence to reverse its  valuation  allowances  related to
certain foreign tax jurisdictions.

       The Company estimates  that its fourth  quarter cash income taxes will be
$4 million to $6 million,  principally  comprised of Argentine  income taxes and
nominal  alternative  minimum tax in the United  States as the Company  benefits
from its net operating loss  carryforwards  in the United States and Canada.  In
the future,  the  Company's  effective tax rate on earnings in the United States
will approximate  statutory rates as a result of the aforementioned  reversal of
deferred tax valuation allowances.

       Cumulative  effect of  change  in  accounting  principle.  As  previously
discussed, the Company adopted the provisions of SFAS 143 on January 1, 2003 and
recognized  a $15.4  million  benefit  from the  cumulative  effect of change in
accounting  principle,  net of $1.3  million of  associated  Argentine  deferred
income taxes.

       On January 1, 2003,  the Company also adopted the provisions of SFAS 145,
the  provisions of which did not result in a cumulative  effect  adjustment.  In
accordance  with the provisions of SFAS 145, the Company  reclassified  to other
expense  extraordinary  losses  from the  early  extinguishment  of debt of $2.8
million and $19.5 million  realized during the three month periods ended June 30
and September 30, 2002, respectively.

       See Note B  of Notes to Consolidated  Financial  Statements  included  in
"Item  1.  Financial  Statements"  for  additional   information  regarding  the
Company's adoption of SFAS 143 and SFAS 145.

Capital Commitments, Capital Resources and Liquidity

       Capital  commitments.  The  Company's  primary  needs  for  cash  are for
exploration,  development and acquisitions of oil and gas properties,  repayment
of contractual obligations and working capital obligations.

       Oil and gas properties.  The Company's cash expenditures for additions to
oil and gas properties  during the three and nine month periods ended  September
30, 2003 totaled $134.9 million and $522.0 million,  respectively. The Company's
additions  to oil and gas  properties  were funded by $222.5  million and $546.7
million of net cash provided by operating  activities  during the three and nine
month periods  ended  September 30, 2003,  respectively.  The Company's  capital
expenditures  during the three  months ended  September  30, 2002 were funded by
$87.7  million of net cash  provided by operating  activities,  $59.9 million of
proceeds  from the  disposition  of  assets  and  borrowings  under  the  Credit
Facility.  The  Company's  capital  expenditures  during the nine  months  ended
September  30,  2002 were  funded  by $228.3  million  of net cash  provided  by
operating activities,  $118.8 million of proceeds from the disposition of assets
and  proceeds  from the April 2002 sale of 11.5  million  shares of common stock
(the "Stock Offering").

       Contractual obligations.  The Company's  contractual  obligations include
long-term debt, operating leases, Btu swap agreements (which are fixed in amount
and are not  subject  to market  risk),  terminated  commodity  hedges and other
contracts.  During the nine months ended September 30, 2003, the Company reduced
its long-term debt by $47.2 million,  reduced its obligations under the Btu swap
agreements by $4.9 million and locked-in $24.2 million of remaining  liabilities
associated  with the  termination of commodity  hedges prior to their  scheduled
maturity.   The  Company's  contractual   obligations  for  which  the  ultimate
settlement  amounts  are not fixed and  determinable  are  currently  limited to
derivative  contracts that are sensitive to future changes in commodity  prices.
See "Item 3.  Quantitative and Qualitative  Disclosures About Market Risk" for a
table of changes in the fair value of the Company's  derivative  contract assets
and liabilities during the nine months ended September 30, 2003.

       Working capital. Funding for the Company's working capital obligations is
provided  by  internally-generated  cash  flow.  Funding  for the  repayment  of
principal and interest on outstanding debt and the Company's capital expenditure
program may be provided by any  combination of  internally-generated  cash flow,
proceeds from the disposition of non- strategic assets or alternative  financing
sources as discussed in "Capital resources" below.

       Capital resources.  The Company's primary  capital resources are net cash
provided  by  operating  activities,  proceeds  from  financing  activities  and
proceeds  from sales of  non-strategic  assets.  The Company  expects that these
resources  will be  sufficient  to  fund  its  capital  commitments  during  the
remainder of 2003.

       Operating activities.  Net cash  provided by  operating activities during
the three and nine month  periods ended  September 30, 2003 were $222.5  million
and $546.7  million,  respectively,  as  compared  to $87.7  million  and $228.3
million  for the same  respective  periods  in 2002.  The  increase  in net cash
provided by operating  activities  during the three and nine month periods ended
September  30,  2003,  as compared to the same  respective  periods in 2002,  is
primarily due to higher gas production and higher commodity prices.

       Financing activities.  Net cash  used in  financing activities during the
three and nine month  periods  ended  September  30, 2003 was $94.4  million and
$48.6  million,  respectively.  In  comparison,  net cash  provided by financing
activities  was $90.4 million and $163.8 million during the three and nine month
periods  ended  September 30, 2002,  respectively.  During the nine months ended
September 30, 2003,  net cash provided by operating  activities has been used to
fund the Company's capital  projects,  repay borrowings of $117.7 million during
the first half of 2003,  including  normal  closing  adjustments,  to acquire an
additional 25 percent  working  interest in the Falcon field,  the Harrier field
and  surrounding  satellite  prospects  in the  deepwater  Gulf of Mexico and to
reduce  long-term debt by $47.5  million.  During the third quarter of 2003, net
cash  provided  by  operating  activities  increased  while  net  cash  used for
investing  activities  declined allowing the Company to reduce long-term debt by
$92.0 million. During the three and nine month periods ended September 30, 2002,
the Company used a portion of the $236.0  million of net proceeds from the Stock
Offering to fund a portion of the net cash used in investing activities and to
repay a portion of its long-term debt and other noncurrent liabilities.

       During August and  February 2003,  the Company entered into interest rate
swap  contracts to hedge a portion of the fair value of its 9-5/8 percent senior
notes.  Under the terms of the interest rate swap contracts  entered into during
August (the "August Contracts"),  the Company was to receive a fixed annual rate
of 9-5/8  percent  on  $300.0  million  notional  amount  and  agreed to pay the
counterparties a variable  rate on  the notional amount  equal to  the six-month

                                       34




                        PIONEER NATURAL RESOURCES COMPANY


LIBOR, reset  semi-annually,  plus a weighted average margin ("LIBOR Margin") of
521.0 basis points.  The terms of the interest rate swap contracts  entered into
during  February  2003 (the  "February  Contracts")  differed  from those of the
August  Contracts  only in notional  amount and LIBOR  Margin,  which terms were
$250.0 million and 566.4 basis points, respectively.  During September 2003, the
Company terminated the August Contracts for $10.1 million of cash proceeds.  The
cash proceeds were comprised of $1.2 million of settlement gains attributable to
the period from August 2003  through the date of  termination  and $8.9  million
attributable  to the fair value,  on the date of  termination,  of the remaining
term of the  August  Contracts.  During May 2003,  the  Company  terminated  the
February  Contracts for $11.4 million of cash  proceeds.  The cash proceeds were
comprised of $2.0 million of settlement  gains  attributable  to the period from
February 2003 through the date of termination  and $9.4 million  attributable to
the  fair  value,  on the  date of  termination,  of the  remaining  term of the
February Contracts.

       Outstanding borrowings  under the Credit Facility  totaled $218.0 million
as of September 30, 2003,  excluding  $28.8 million of undrawn letters of credit
issued under the Credit  Facility.  The weighted  average  interest rates on the
Company's  indebtedness for the three and nine month periods ended September 30,
2003 were 5.2 percent and 5.3 percent,  respectively, as compared to 5.8 percent
and 6.4 percent for the same respective periods in 2002, taking into account the
effect of lower market interest rates and the Company's interest rate swaps.

       As the Company  pursues its strategy,  it may  utilize  various financing
sources,  including  fixed  and  floating  rate  debt,  convertible  securities,
preferred  stock or common  stock.  The  Company  may also issue  securities  in
exchange for oil and gas  properties,  stock or other interests in other oil and
gas  companies  or  related  assets.  Additional  securities  may be of a  class
preferred  to common  stock  with  respect  to such  matters  as  dividends  and
liquidation  rights and may also have other rights and preferences as determined
by the Company's Board of Directors.

       Sales of assets.  During the three and nine month periods ended September
30,  2003,  proceeds  from the sale of assets  totaled  $9.3  million  and $35.0
million,  respectively,  as compared to $59.9 million and $118.8 million for the
same  respective  periods in 2002.  The Company's 2003 asset  divestitures  were
primarily comprised of derivative assets and Gulf of Mexico shelf prospects,  in
which a  partial  interest  was  sold to  Woodside.  The  Company's  2002  asset
divestitures were primarily comprised of derivative assets.

       Book capitalization  and liquidity.  The  Company's  total  debt was $1.6
billion as of September  30, 2003 and $1.7 billion as of December 31, 2002.  The
Company's  total book  capitalization  at September  30, 2003 was $3.3  billion,
consisting  of total  debt of $1.6  billion  and  stockholders'  equity  of $1.7
billion.  Consequently,  the  Company's  debt to total  book  capitalization  at
September  30, 2003 was 48.6 percent and at December 31, 2002 was 54.8  percent.
The  Company's  ratio  of  current  assets  to  current  liabilities  was .61 at
September 30, 2003 and at December 31, 2002 was .54.  Including $28.8 million of
undrawn and  outstanding  letters of credit,  the Company had $328.2  million of
unused  borrowing  capacity  available under its Credit Facility as of September
30, 2003.

       During the fourth quarter of 2003,  the Company anticipates that net cash
provided by operating activities, based on current commodity prices, will exceed
budgeted capital  expenditures and contractual  obligations and be sufficient to
reduce long-term debt by an additional $25 million to $50 million.

New Accounting Interpretation and Recent Developments

       During January 2003,  the Financial  Accounting  Standards  Board  issued
Interpretation No. 46, "Consolidation of Variable Interest Entities" ("FIN 46"),
which requires the  consolidation  of certain entities that are determined to be
variable interest entities  ("VIE's").  An entity is considered to be a VIE when
either  (i) the  entity  lacks  sufficient  equity  to  carry  on its  principal
operations, (ii) the equity owners of the entity cannot make decisions about the
entity's  activities  or (iii) the entity's  equity  neither  absorbs  losses or
benefits  from gains.  For VIEs  created  subsequent  to January 31,  2003,  the
provisions of FIN 46 must be applied immediately. For VIEs created prior to that
date, the adoption of FIN 46 is required for all reporting periods subsequent to
December 15, 2003.

       Subsequent to January 31, 2003,  the Company has not acquired an interest
in any VIEs that would require immediate consolidation under FIN 46. The Company
is currently reviewing its financial  arrangements to determine whether any VIEs
existed prior to January 31, 2003 that should be  consolidated by the Company in
accordance with FIN 46. The Company does not believe that the  consolidation  of
VIEs that existed prior to January 31, 2003, if any, will have a material impact
on its future financial position, results of operations or liquidity.

                        PIONEER NATURAL RESOURCES COMPANY


       In its recent review of  registrants' filings,  the staff of  the SEC has
taken the position  that  Statement of Financial  Accounting  Standards No. 142,
"Goodwill  and Other  Intangible  Assets"  ("SFAS  142"),  requires  oil and gas
entities to  separately  report on their  balance  sheets the costs of leasehold
mineral interests  acquired after June 30, 2001,  including related  accumulated
depletion, as intangible assets and provide related disclosures. The Company has
historically included producing leasehold costs in the proved properties caption
on its balance sheet since the value of the leases is inseparable from the value
of the related oil and gas reserves.  This classification is consistent with the
provisions of Statement of Financial  Accounting  Standards  No. 19,  "Financial
Accounting  and  Reporting  by Oil and Gas  Producing  Companies",  and standard
industry practice.  Almost all costs included in the unproved properties caption
on the  balance  sheet  are  leasehold  mineral  interests  that  are  regularly
evaluated  for  impairment  based on lease term and drilling  activity.  The SEC
staff has referred the question of SFAS 142  applicability  for consideration by
the Emerging  Issues Task Force. If the provisions of SFAS 142 are determined to
be  applicable  to oil and gas leasehold  mineral  interests,  reclassifications
within  property,  plant and equipment on the  Consolidated  Balance  Sheets and
additional  disclosures  may be required.  The Company does not believe that the
provisions  of SFAS 142, if determined  to be  applicable,  will have a material
impact on its  financial  position,  results  of  operations  or  liquidity.  At
September 30, 2003, the Company had cumulative expenditures of no more than $450
million on costs of leasehold  mineral  interests  since June 30, 2001, that are
included in oil and gas properties in the Company's Consolidated Balance Sheet.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

       The following quantitative  and qualitative disclosures about market risk
are  supplementary to the quantitative and qualitative  disclosures  provided in
the Company's  Annual Report on Form 10-K for the year ended  December 31, 2002.
As such, the information contained herein should be read in conjunction with the
related  disclosures  in the  Company's  Annual Report on Form 10-K for the year
ended December 31, 2002.

       The following table  reconciles the  changes that  occurred  in the  fair
values of the Company's open derivative  contracts  during the first nine months
of 2003:


                                                       Derivative Contract Assets (Liabilities)

       The following  disclosures provide  specific  information  about material
changes that have occurred since December 31, 2002 in the Company's portfolio of
financial instruments. The Company may recognize future earnings gains or losses
on these instruments from changes in market commodity prices,  interest rates or
foreign exchange rates.

       Interest rate sensitivity.  During August and February 2003,  the Company
entered into interest  rate swap  contracts to hedge a portion of the fair value
of its 9-5/8  percent  senior  notes.  Under the terms of the interest rate swap
contracts entered into during August (the "August  Contracts"),  the Company was
to  receive a fixed  annual  rate of 9-5/8  percent on $300.0  million  notional
amount and agreed to pay the  counterparties  a  variable  rate on the  notional
amount  equal to the  six-month  LIBOR,  reset  semi-annually,  plus a  weighted
average margin ("LIBOR Margin") of 521.0 basis points. The terms of the interest
rate swap contracts entered into during February 2003 (the "February Contracts")
differed from those of the August  Contracts  only in notional  amount and LIBOR
Margin,  which terms were $250.0  million and 566.4 basis points,  respectively.
During  September  2003, the Company  terminated the August  Contracts for $10.1
million of cash  proceeds.  The cash proceeds were  comprised of $1.2 million of
settlement gains attributable to the period from August 2003 through the date of
termination  and $8.9  million  attributable  to the fair value,  on the date of
termination, of the remaining term of the August Contracts. During May 2003, the
Company terminated the February Contracts for

                        PIONEER NATURAL RESOURCES COMPANY


$11.4 million of cash proceeds. The cash proceeds were comprised of $2.0 million
of settlement  gains  attributable  to the period from February 2003 through the
date of termination and $9.4 million attributable to the fair value, on the date
of termination, of the remaining term of the February Contracts.

       The following table  provides information  about the  debt obligations of
the Company that are sensitive to changes in interest  rates as of September 30,
2003. The table presents the debt  obligations by maturity  dates,  the weighted
average interest rates expected to be paid on the debt given current contractual
terms and market  conditions and the debt's estimated fair value. For fixed rate
debt, the weighted average interest rate represents the contractual  fixed rates
that the Company was obligated to  periodically  pay on the debt as of September
30, 2003.  For variable  rate debt,  the average  interest rate  represents  the
average  rates being paid on the debt  projected  forward  proportionate  to the
forward yield curve for the six-month LIBOR.

       Commodity price sensitivity.  During the first nine  months of 2003,  the
Company entered into certain oil and gas hedge  derivatives and terminated other
oil and gas hedge  derivatives.  The following tables provide  information about
the Company's oil and gas derivative  financial  instruments of the Company that
were  sensitive to oil and gas price  changes as of September  30, 2003.  All of
these oil and gas derivative financial instruments qualified as hedges.

(1)  To minimize  basis risk,  the Company enters into basis swaps for a portion
     of its gas hedges to connect the index price of the hedging instrument from
     a NYMEX index to an index which reflects the geographic area of production.

     collar contracts and, accordingly, the effects of the basis swaps have been
     presented together with the associated contracts.
