          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 Btu's;  "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  respect 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")   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 June 30, 2003 and for the three and
six month  periods  ended June 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 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 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  Note  E for  additional
information regarding the Company's asset retirement obligations.

       The following pro forma data  summarizes the Company's net income and net
income per share as if the Company had  adopted  the  provisions  of SFAS 143 on
January 1, 2002,  including an associated pro forma asset retirement  obligation
on that date of $60.2 million:

       Adoption of SFAS 145.  On  January  1,  2003,  the  Company  adopted  the
provisions  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 the  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  it's the  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 net income of the three and six month  periods ended June 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. The following table
illustrates the effect on net income and net income per share 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 employee compensation:

NOTE C.     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 D.     Derivative Financial Instruments

       Fair value hedges.  The Company  monitors capital  markets and  trends to
identify  opportunities to enter into and terminate interest rate swaps with the
objective of minimizing  costs of capital.  During  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,  the Company was to receive a fixed  annual rate of 9-5/8  percent on
$250 million  notional  amount and agreed to pay the  counterparties  a variable
rate on the notional  amount equal to the  six-month  London  Interbank  Offered
Rate, reset semi-annually, plus a weighted average margin of 566.4 basis points.
During May 2003, the Company  terminated the 9-5/8 percent senior notes interest
rate swap 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
interest rate swap contracts.  The $9.4 million of proceeds  attributable to the
fair value of the remaining term of the interest rate swap contracts is included
in  "Proceeds  from  disposition  of  assets"  in  the  Company's   Consolidated
Statements  of Cash  Flows for the three and six month  periods  ended  June 30,
2003.

       As of June 30,  2003,  the carrying value of the Company's long-term debt
in the  accompanying  Consolidated  Balance  Sheets  included  $32.8  million of
incremental  liability  attributable  to  unamortized  deferred  hedge gains and
losses realized from fair value hedge  agreements  terminated  during 2003, 2002
and 2001.  The  amortization  of  deferred  hedge gains  reduced  the  Company's
reported  interest  expense by $6.0  million and $2.7  million  during the three
month periods ended June 30, 2003 and 2002,  respectively,  and by $11.9 million
and $5.6  million  during the six month  periods  ended June 30,  2003 and 2002,
respectively.

      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, from time to time, 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.

        Natural gas liquids prices. During the three and six month periods ended
June 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 June

       Hedge ineffectiveness and excluded items.  During the three month periods
ended June 30,  2003 and 2002,  the  Company  recognized  other  expense of $503
thousand and $268 thousand, respectively, related to the ineffective portions of
its cash flow hedging  instruments.  During the six month periods ended June 30,
2003 and 2002,  the Company  recognized  other expenses of $2.3 million and $346
thousand,  respectively,  related  to the  ineffective  portion of its cash flow
hedging instruments.

       Accumulated other comprehensive income (loss) ("AOCI")  -  deferred hedge
gains (losses), net. As of June 30, 2003 and December 31, 2002, "AOCI - deferred
hedge gains (losses), net" represented net deferred losses of $152.8 million and
net deferred  gains of $9.6 million,  respectively.  The "AOCI - deferred  hedge
gains (losses), net" balance as of June 30, 2003 was comprised of $188.3 million
of unrealized  deferred hedge losses on the effective portions of open commodity
cash flow hedges and $35.5 million of net deferred gains on terminated cash flow
hedges.  The decrease in "AOCI - deferred hedge gains (losses),  net" during the
six months ended June 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  deferred  hedge  losses to net
income as  derivatives  matured by their terms.  The  unrealized  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 month period ending June 30, 2004,  the Company expects
to reclassify  $105.4 million of net deferred  losses  associated with open cash
flow hedges and $12.3  million of net  deferred  gains on  terminated  cash flow
hedges from "AOCI - deferred hedge gains (losses), net" to oil and gas revenue.

       The  following  table  sets  forth  the  scheduled  reclassifications  of
deferred  hedge  gains and losses on  terminated  cash flow  hedges that will be

NOTE F.     Commitments and Contingencies

      Legal actions. The Company is party to various legal actions incidental to
its business,  including,  but not limited to, the proceedings  described below.
The majority of these lawsuits primarily involve claims for damages arising from
oil and gas leases and ownership  interest  disputes.  The Company believes that
the ultimate disposition of these legal actions will not have a material adverse
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 $32.5  million,  plus  prejudgment  interest.
However,  the Company believes it has valid defenses to 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  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  lawsuit  was
determined  adversely  to 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 reasoned 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  limiting  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 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 June 30,
2003, the Company has settled $21.7 million of the original claim amounts. As of
June 30, 2003 and December 31, 2002,  the Company had on deposit $10.6  million,
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 G.     Income Per Share Before Cumulative Effect of Change in
            Accounting Principle

       Basic income per  share before  cumulative effect of change in accounting
principle is computed by dividing income before  cumulative  effect of change in
accounting principle by the weighted average number of common shares outstanding
for the  period.  The  computation  of  diluted  net  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 net income 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  shares  outstanding  for the three and six month periods ended June 30,
2003 and 2002:

(a)  Common stock options to purchase  1,364,706  shares and 1,639,032 shares of
     common  stock were  outstanding  but not  included in the  computations  of
     diluted  income per share for the three month  periods  ended June 30, 2003
     and 2002,  respectively,  and common  stock  options to purchase  1,368,612
     shares  and  1,971,461  shares of common  stock  were  outstanding  but not
     included in the  computations of diluted income per share for the six month
     periods  ended June 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.

(b)  On May 15, 2003,  the Company  awarded 4,425 shares of restricted  stock in
     partial  payment of  director  fees.  These  director  fee awards vest on a
     quarterly  pro-rata  basis during the year ended May 15,  2004.  During the
     three  months  ended March 31, 2003,  the Company  issued 9,500  restricted
     shares of the  Company's  common  stock to key  employees.  The  restricted
     shares issued to the key employees vest on the third anniversaries of their
     issuances.

NOTE H.     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. 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" table 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
("Pioneer" or the "Company"), 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 or implement its business plans, access to and cost of capital,
uncertainties  about  estimates  of  reserves,  quality  of  technical  data and
environmental  risks,  acts of war and  terrorism.  These  and  other  risks are
described  in the  Company's  2002 Annual  Report on Form 10-K that is available
from the United States Securities and Exchange Commission ("SEC").

Financial and Operating Performance

       The Company's  financial and operating performance for the second quarter
of 2003 was highlighted by continued  production  growth,  primarily  associated
with a full quarter of production  from the Company's  deepwater  Gulf of Mexico
Canyon Express gas project and the  Company-operated  Falcon field, which is the
second  of five  significant  projects  that  the  Company  plans  to  bring  on
production  through early 2004.  The production  growth  realized by the Company
together  with  favorable  worldwide  oil and North  American  gas  prices  have
resulted in significant  increases in Pioneer's net income and net cash provided
by operating  activities  during the three and six month  periods ended June 30,
2003, as compared to the same periods of 2002.

       The Company reported net income of $77.2 million ($.65 per diluted share)
and $161.4 million ($1.36 per diluted share) for the three and six month periods
ended June 30, 2003,  respectively,  as compared to net income of $11.1  million
($.10 per share) and $9.2 million ($.08 per share) for the same periods of 2002.
The Company's net income for the six months ended June 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 Accounting  Principles No. 143,  "Accounting  for Asset  Retirement
Obligations" ("SFAS 143"). See Notes B and E of Notes to Consolidated  Financial
Statements included in "Item 1. Financial Statements" for additional information
regarding the Company's adoption of new accounting pronouncements.

       The  Company's  net cash  provided  by operating  activities  was  $189.9
million and $324.2  million for the three and six month  periods  ended June 30,
2003, respectively, representing increases of $99.3 million, or 110 percent, and
$183.6  million,  or 131  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 six month periods ended June 30, 2002
was $90.6  million and $140.6  million,  respectively.  During the three  months
ended  June 30,  2003,  the  Company  used its net cash  provided  by  operating
activities,  together  with  proceeds from the  disposition  of assets,  to fund
$134.3 million of additions to oil and gas properties and to repay $57.2 million
of long-term  debt.  During the six months ended June 30, 2003, the Company used
its net cash provided by operating  activities,  together with proceeds from the
disposition  of assets  and  borrowings  under the  Company's  corporate  credit
facility, to fund $387.1 million of additions to oil and gas properties.

Drilling Highlights

        During the first six months of 2003, the Company incurred $395.1 million
in capital  expenditures  including  $124.7 million for development  activities,
$140.7 million for  exploration  activities and $129.7 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 six months
ended June 30, 2003:

       Domestic. The Company spent $301.4 million during the first six months of
2003 on acquisition,  drilling and seismic activities in the Gulf of Mexico/Gulf
Coast, 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 $206.1 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 discussed  above,  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 June 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
           third 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,  while  a  second  subsea  tie-back  development  well is
           planned to be drilled during the fourth quarter of 2003. Devils Tower
           production  is scheduled  to begin  in the  first quarter of 2004 and
           will be phased in as the  wells are  individually  completed from the
           spar.  Pioneer holds a  25 percent  working interest in the projects.
           The Company also  has plans to drill another  exploratory well by the
           end of 2003 that  would be completed as a third subsea tie-back well,
           if successful.

       o   Harrier - The Company  discovered the  Harrier field during the first
           quarter of 2003,  encountering over 350 feet  of gas-bearing  sand in
           a  single  zone.  Pioneer  operates  the  block  with  a 100  percent
           working interest, subsequent to the acquisition discussed above,  and

                        PIONEER NATURAL RESOURCES COMPANY


           is  developing  the  field as  a  single-well  subsea tie-back to the
           Falcon field  facilities  which were  designed to be  expandable.  To
           accommodate  incremental  Harrier  field  production  and   potential
           throughput  associated  with   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 Harrier field  in early 2004 with  combined daily gas production
           from  Falcon field and  Harrier field expected  to reach 275 MMcf per
           day.

       The Devils  Tower and  Harrier  field  projects  were  impacted by recent
severe  weather and strong  currents in the Gulf of Mexico.  Although the severe
weather and strong currents did not result in meaningful change to the projects'
schedules,   future  weather-related   delays,  if  extensive,   may  result  in
unavoidable schedule changes.

       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 and plans to drill two additional exploration prospects
later this year in  conjunction  with the  completion  of the Harrier  well.  If
successful,  these Falcon area  prospects  could also be tied back to the Falcon
field to utilize excess  pipeline and  processing  capacity.  Additionally,  the
Company controls 32 blocks in the area.

       During January 2003,  the Company announced a joint exploration agreement
with Woodside 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 two wells under this
joint agreement were unsuccessful. The third well is in progress and the results
are expected to be known in August 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 half 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 $33.4 million during the first six
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.

       Permian Basin area.  In the  Permian Basin area,  the Company spent $34.1
million during the first six months of 2003 primarily on development drilling in
the Spraberry field. The Company plans to drill  approximately  150 wells in the
Spraberry field during 2003.

       Mid-Continent area. I n the  Mid-Continent area,  the Company spent $27.8
million  during the first six months of 2003,  primarily  in the West  Panhandle
field where the Company plans to drill  approximately  100 wells this year.  The
Company also plans to drill approximately 30 Hugoton wells later this year.

       Argentina.  In Argentina, the Company spent $26.1 million of acquisition,
drilling and seismic  capital  during the first six months of 2003. The majority
of costs  was spent to drill  extension  and  development  wells  targeting  oil
reserves in the Neuquen Basin.

       Canada.  In Canada,  the  Company  spent  $36.7  million of  acquisition,
drilling and seismic  capital during the first six months of 2003,  primarily in
the  Chinchaga,  Martin Creek and Ladyfern  areas that are only  accessible  for
drilling  during the winter months.  Pioneer  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  $30.9  million of acquisition,
drilling  and  seismic  capital  during  the first  six  months of 2003 in South
Africa, Tunisia and Gabon.

       South Africa. In South Africa, the Company spent $19.6 million of capital
to drill three exploratory wells and to continue  development of its Sable field
that is expected to have first oil production during August 2003. The production
delay to August  2003 is  primarily  attributable  to the owner of the  floating
production  facility being leased by Pioneer  encountering  unexpected  problems
with the new  compression  equipment  installed  on the  facility,  resulting in
extensive reconditioning. Oil sales are expected by late in the third quarter as
soon as sufficient inventory has been built to offload oil for the first shuttle
delivery to onshore  facilities.  During the second quarter of 2003, the Company
drilled its three 2003 planned  exploratory wells in South Africa, none of which
were commercial.

       Tunisia. In Tunisia, the Company spent $9.7 million of capital during the
first six months of 2003. The Company began  development  activities on its Adam
discovery which began production  during the second quarter of 2003. First sales
are expected during the fourth quarter.  The Company also drilled an exploration
well on its Jorf permit which was unsuccessful.

       The  Company  drilled  two  exploration  wells on  its  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 block,  Pioneer is participating in the
Adam 2  development  well,  the  first  development  well in the new 860  square
kilometer  Adam  concession.  The  discovery  well,  Adam 1, has been  producing
through nearby  facilities at the Oued Zar field at a gross  stabilized  rate of
over 3,500 Bbls per day since late May 2003.  Following  the  completion  of the
Adam 2 well,  the  Company  plans to  drill  the  Hawa  exploration  well in the
southern  portion of the Adam concession  where Pioneer has a 28 percent working
interest.

       Gabon.  In Gabon, the Company spent $1.6 million during the first half of
2003. The Company is awaiting final government approval of renegotiated terms in
Gabon. Upon formal approval of terms, the Company expects to commence a drilling
program early in 2004 as part of its development plan for the project.

Results of Operations

       Oil and gas revenues. Revenues from oil and gas operations totaled $340.0
million and $621.1  million for the three and six month  periods  ended June 30,
2003,  respectively,  compared to $172.4 million and $338.0 million for the same
respective  periods of 2002.  The  increase in oil and gas  revenues  during the
three and six month periods ended June 30, 2003, as compared to the same periods
of 2002,  was  principally  attributable  to initial  sales  from the  Company's
deepwater Gulf of Mexico Canyon Express and Falcon field gas projects, increased
gas sales in Argentina and to commodity price increases.  As expected,  declines
in Canadian production partially offset the above described increases to oil and
gas revenues.

       The following table provides  the Company's  volumes and average reported
prices, including the results of hedging activities, for the three and six month
periods ended June 30, 2003 and 2002:

       On a BOE  basis,  worldwide  average  daily  production  increased  by 45
percent  and 31 percent  during the three and six month  periods  ended June 30,
2003,  respectively,  as compared to the same periods in 2002. During the second
quarter  of 2003 as  compared  to the  second  quarter  of 2002,  worldwide  oil
production  increased by four percent; NGL production increased by four percent;
and gas  production,  augmented  by a full quarter of  production  from both the
Canyon  Express and Falcon field gas projects,  increased by 83 percent.  During
the first half of 2003,  as  compared to the first half of 2002,  worldwide  oil
production declined by two percent;  NGL production  increased by three percent;
and gas  production,  augmented by six months of production  from Canyon Express
and production since March from the Falcon field,  increased by 60 percent.  Per
BOE average daily production, on a second-quarter to second-quarter  comparison,
increased  by 56 percent in the  United  States and by 32 percent in  Argentina,
while  production  in Canada  decreased by 13 percent.  During the first half of
2003 as compared to the first half of 2002,  per BOE  average  daily  production
increased by 41 percent in the United  States and by 11 percent in Argentina and
declined by 12 percent in Canada.

       Third quarter 2003  production is  expected to average 150,000 to 165,000
BOE per day and total 2003 production is expected to range from 55 million to 60
million BOE.

       With a full year of production from the new fields brought on in 2003 and
the addition of Harrier  field and Devils Tower  production  in early 2004,  the
Company expects 2004 production to range from 63 million to 75 million BOE.

       As discussed above,  oil and gas  revenues  for the  three and  six month
periods  ended  June 30,  2003  were  positively  impacted  by  commodity  price
increases.  Comparing the second quarter of 2003 to the same period in 2002, the
Company's average worldwide oil price increased three percent, average worldwide
NGL prices  increased 23 percent and average  worldwide gas prices  increased 65
percent. Comparing the first six months of 2003 to the same period in 2002,  the

                        PIONEER NATURAL RESOURCES COMPANY


Company's average worldwide oil price increased seven percent, average worldwide
NGL prices  increased 57 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) lock in prices to protect the economics  related to
certain capital projects. During the three and six months periods ended June 30,
2003,  the Company's  commodity  price hedges  decreased oil and gas revenues by
$22.6 million and $73.0 million, respectively, as compared to increasing oil and
gas revenues by $3.9 million and $36.2 million  during the same periods in 2002.
See Note D 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 six month periods ended June 30, 2003 and 2002.

       During July 2003,  the Company  entered into new  oil swap  contracts for
2,000  Bbls per day for  September  2003 with  average  per Bbl fixed  prices of
$30.18  and gas  swap  contracts  for  180,000  Mcf per  day for the  period  of
September 2003 through December 2003with average per Mcf fixed prices of $4.85.

       Gain on  disposition  of assets.  During the three and six month  periods
ended June 30,  2003,  the Company  recorded  $104  thousand  and $1.5  million,
respectively,  of net gains on the  disposition  of assets,  as compared to $1.1
million  and $1.0  million,  respectively,  of net gains on the  disposition  of
assets during the same periods in 2002.

       Production costs.  During the  three and six month periods ended June 30,
2003,  total  production  costs per BOE averaged $4.80 and $5.13,  respectively,
representing  a decrease of $.18 per BOE (four  percent) and an increase of $.08
per BOE (two percent),  respectively, as compared to production costs per BOE of
$4.98 and $5.05  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 decrease in production  costs per BOE  during the  three months ended
June 30,  2003,  as  compared to the same period in 2002,  is  primarily  due to
decreases in workover  costs, ad valorem taxes and production  taxes,  partially
offset by an increase in field fuel expense as a result of higher gas prices and
increased lease operating  expenses.  As compared to the first half of 2002, the
increase  in  production  costs per BOE during the first half of 2003 was due to
increases in production  taxes and field fuel expenses as a result of higher gas
prices,  partially offset by lower lease operating expense, ad valorem taxes and
workover costs.

                                                 ======    ======    ======    ======


       Based on market-quoted  commodity  prices during  July 2003,  the Company
expects third 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.

                        PIONEER NATURAL RESOURCES COMPANY


       Depletion,  depreciation  and  amortization expense.  The Company's total
depletion, depreciation and amortization expense per BOE was $6.95 and $6.55 for
the three and six month periods ended June 30, 2003,  respectively,  as compared
to $5.10 and $5.08 during the three and six month  periods  ended June 30, 2002.
Depletion expense per BOE, the largest component of depletion,  depreciation and
amortization expense, was $6.78 and $6.37 per BOE during the three and six month
periods  ended June 30, 2003,  respectively,  as compared to $4.89 and $4.87 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  third  quarter  2003  depletion,  depreciation and
amortization  expense to average $6.90 to $7.30 per BOE. The potential  increase
is principally attributable to higher cost-basis Sable production volumes.

       Exploration, abandonments, geological and geophysical costs. Exploration,
abandonments,  geological  and  geophysical  costs were $47.0  million and $82.9
million   during  the  three  and  six  month   periods  ended  June  30,  2003,
respectively,  as compared to $17.9  million and $39.0  million  during the same
respective  periods in 2002. The in  exploration,  abandonments,  geological and
geophysical  costs  during the six months of 2003 as  compared  to the first six
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
six  months  ended  June 30,  2003,  the  Company  completed  and  evaluated  73
exploration/extension   wells,  35  of  which  were  successfully  completed  as
discoveries. During the same period in 2002, the Company completed and evaluated
18  exploration/extension  wells,  14 of which were  successfully  completed  as
discoveries.

       The following  table  provides the  Company's geological  and geophysical
costs,  exploratory  dry hole  expense,  lease  abandonments  expense  and other
exploration  expense for the three and six month periods ended June 30, 2003 and
2002:

                        PIONEER NATURAL RESOURCES COMPANY



       The Company  expects  third  quarter  2003  exploration  and  abandonment
expense  to be $25  million to $50  million,  dependent  largely on  exploratory
drilling results and expected seismic expenditures.

       General and administrative expense.  General and  administrative expenses
for the three and six month  periods  ended June 30, 2003 were $13.6 million and
$29.1  million,  respectively,  as compared to $10.8  million and $22.7  million
during the same  respective  periods in 2002.  The increases of $2.8 million and
$6.4 million in general and administrative  expense for the respective three and
six month  periods ended June 30, 2003, as compared to the same periods in 2002,
are primarily due to increases in performance related compensation costs.

       The Company expects third quarter 2003 general and administrative expense
to be approximately $13 million to $15 million.

       Accretion of discount on asset  retirement obligations.  During the three
and six month  periods  ended June 30,  2003,  accretion  of  discount  on asset
retirement  obligations  was $1.2 million and $2.3  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  in
interest expense. The Company's interest expenses during the three and six month
periods   ended  June  30,  2002  include  $632   thousand  and  $1.3   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 E 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  third quarter  2003 accretion of discount on asset
retirement obligations to be approximately $1 million.

       Interest expense.  Interest expense  was $23.8  million and $46.3 million
for the  three and six month  periods  ended  June 30,  2003,  respectively,  as
compared to $24.7 million and $51.1 million for the same  respective  periods in
2002. The decreases of $918 thousand (or four percent) and $4.8 million (or nine
percent) in interest  expense for the three and six month periods ended June 30,
2003,  respectively,  as compared to the same  respective  periods of 2002,  are
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 incurred under the Company's  $575.0 million  corporate credit
facility, the aforementioned separate classification of accretion of discount on
asset retirement  obligations and increases of $503 thousand and $1.5 million in
interest rate hedge gains,  respectively.  Partially offsetting the decreases in
interest  expense  described  above were  reductions  of $1.5  million  and $1.7
million,  respectively,  in interest  capitalized during the three and six month
periods ended June 30, 2003, as compared to the same respective periods in 2002.

       The Company expects third quarter 2003 interest expense to be $23 million
to $25 million.

       Other expenses.  Other expenses for the three and six month periods ended
June 30, 2003 were $5.6 million and $10.8 million,  respectively, as compared to
$7.7 million and $16.0 million for the same respective periods in 2002. The $2.1
million  decrease in other expenses during the three months ended June 30, 2003,
as compared  to the same period of 2002,  is  primarily  attributable  to a $2.8
million loss recognized from the early  extinguishment of higher yielding senior
notes in 2002. The $5.2 million  decrease in other expense during the six months
ended June 30,  2003,  as  compared  to the same  period of 2002,  is  primarily
attributable  to a $6.5 million  decrease in foreign  exchange  transaction  and
remeasurement  charges  and a  $2.8  million  loss  recognized  from  the  early
extinguishment  of higher yielding senior notes in 2002,  partially  offset by a
$2.0  million  increase in the  ineffective  portions of  commodity  price hedge
losses.  See  "Cumulative  effect of change in accounting  principle"  presented
below for information  regarding the classification of 2002 extraordinary losses
on the early extinguishment of debt.


                                       32




                        PIONEER NATURAL RESOURCES COMPANY


       Income tax provisions.  During the three and six month periods ended June
30, 2003, the Company  recognized income tax provisions of $2.6 million and $4.9
million,  respectively,  that were primarily  attributable to Argentine  taxable
income and a $600 thousand  United  States  alternative  minimum tax  provision.
During  the  three  and six month  periods  ended  June 30,  2002,  the  Company
recognized  income tax  provisions  of $1.4 million and $1.0  million,  of which
amounts $1.2  million and $659  thousand,  respectively,  were  attributable  to
Argentine taxable income. The income tax provision for the six months ended June
30, 2003 is net of a $1.3 million  provision that is associated with the benefit
recognized  from the adoption of SFAS 143 during the first  quarter of 2003 (see
"Cumulative effect of change in accounting principle").

       Due to uncertainties regarding the Company's utilization of net operating
loss carryforwards and other credit  carryforwards,  the Company has established
valuation  reserves to reduce the carrying value of its deferred tax assets. The
Company continues to monitor oil and gas commodity price outlooks and forecasted
capital  spending plans,  production  volumes and taxable income and will reduce
its  deferred  tax asset  valuation  reserves if it becomes more likely than not
that they  will be  utilized  prior to their  scheduled  maturity. The Company's
financial  results have  improved  substantially  during 2003 as a result of the
combined affects of significant production growth and improved commodity prices.
Further   production  growth  is  anticipated  from  projects   currently  under
development  that will be completed  during the next six to eight months.  These
circumstances,  combined  with a stable  outlook  for future  commodity  prices,
increase the likelihood that the Company may generate  sufficient future taxable
income to utilize  its net  operating  loss and other tax  credit  carryforwards
prior to their scheduled expiration.

       The Company estimates that its third quarter income tax provision will be
$4 million to $6 million,  principally  comprised of Argentine  income taxes and
minimal  alternative  minimum tax in the United  States as the Company  benefits
from its net operating loss carryforwards in the United States and Canada.

       Cumulative effect of change in accounting principle. As previously noted,
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 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  recorded 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 six month  periods  ended June 30,
2003 totaled  $134.3  million and $387.1  million,  respectively.  The Company's
second quarter 2003  additions to oil and gas  properties  were funded by $189.9
million of net cash  provided  by  operating  activities.  During the six months
ended June 30, 2003,  the  Company's  additions to oil and gas  properties  were
funded by $324.2  million of net cash  provided by operating  activities,  $25.7
million of proceeds  from the  disposition  of assets and  borrowings  under the
Company's corporate credit facility.  The Company's capital  expenditures during
the three  months  ended June 30, 2002 were funded by $90.6  million of net cash
provided by operating activities,  $7.3 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").  The Company's capital expenditures during the six
months ended June 30, 2002 were funded by $140.6 million of net cash provided by
operating  activities,  $58.9 million of proceeds from the disposition of assets
and proceeds from the Stock Offering.

       Contractual obligations.  The Company's  contractual  obligations include
long-term debt,  operating  leases,  Btu swap agreements,  terminated  commodity


                                       33




                        PIONEER NATURAL RESOURCES COMPANY


hedges  and other  contracts.  During the six months  ended June 30,  2003,  the
Company  increased its long-term debt by $42.2 million,  reduced its obligations
under the Btu swap  agreements  by $3.2 million and  locked-in  $46.0 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 six months ended June 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 in 2003.

       Operating activities.  Net cash provided by  operating  activities during
the three and six month  periods  ended June 30,  2003 were  $189.9  million and
$324.2  million,  respectively,  as compared to $90.6 million and $140.6 million
for the same  respective  periods in 2002.  The increase in net cash provided by
operating activities during the three and six month periods ended June 30, 2003,
as  compared  to the same  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  months  ended June 30, 2003 was $57.3  million  and net cash  provided by
financing  activities  during  the six  months  ended  June 30,  2003 was  $45.7
million.  In  comparison,  net cash provided by financing  activities  was $81.5
million and $73.4 million  during the three and six month periods ended June 30,
2002.  During the three and six month periods  ended June 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 noncurrent liabilities.  During the six months
ended June 30,  2003,  the  primary  source of net cash  provided  by  financing
activities  was first quarter 2003  borrowings  under the Company's $575 million
corporate  credit  facility (the "Credit  Facility").  The borrowings  under the
Credit  Facility  were used to fund the $117.7  million of cash paid,  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.  During the  second  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 $57.2
million.

       During  February  2003,  the  Company  entered  into  interest  rate swap
contracts to hedge the fair value of its 9-5/8 percent senior notes due in 2010.
The  terms  of  these  swap   contracts   obligated   the  Company  to  pay  the
counterparties  a variable  annual rate equal to the six-month  LIBOR plus 566.4
basis points and obligated the counterparties to pay the Company a fixed rate of
9-5/8 percent based on a notional debt amount of $250 million.  During May 2003,
the Company  received $11.4 million of cash from the termination of the interest
rate swap agreements prior to their scheduled maturity.

       Outstanding borrowings under the  Credit Facility totaled  $310.0 million
as of June 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 each of the three and six month periods ended June 30, 2003 was
5.0 percent,  as compared to 6.0 percent and 6.1 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.

                        PIONEER NATURAL RESOURCES COMPANY



       Sales of assets.  During the  three and six month periods ended  June 30,
2003,  proceeds from the sale of assets totaled $10.2 million and $25.7 million,
respectively, as compared to $7.3 million and $58.9 million for the same 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 $1.7
billion as of June 30, 2003 and  December  31, 2002.  The  Company's  total book
capitalization  at June 30, 2003 was $3.1  billion,  consisting of total debt of
$1.7  billion  and  stockholders'  equity  of $1.4  billion.  Consequently,  the
Company's  debt to total  capitalization  at June 30, 2003 and December 31, 2002
was 55 percent. The Company's ratio of current assets to current liabilities was
..52 at June 30, 2003 and .54 at December 31, 2002.  Including  $28.8  million of
undrawn and  outstanding  letters of credit,  the Company had $236.2  million of
unused  borrowing  capacity  available  under its Credit Facility as of June 30,
2003.  During the  remainder  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 $75 million to $100 million  from the  year-end  2002

       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. The following table provides information about
the debt  obligations  that the  Company  was a party to as of June 30, 2003 and
that are  sensitive to changes in interest  rates.  The table  presents the debt
obligations by maturity dates together with the weighted  average interest rates
expected  to be paid on the debt,  given  current  contractual  terms and market
conditions.  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 June 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.

       During  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

receive a fixed annual rate of 9-5/8 percent on $250 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 of
566.4 basis points.  During May 2003,  the Company  terminated the 9-5/8 percent
senior notes interest rate swaps for cash proceeds of $11.4  million,  including

(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.

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

including the CEO and CFO, as  appropriate to allow timely  decisions  regarding
required  disclosure;  and  (ii)  that the  Company's  disclosure  controls  and
procedures are effective.

(b) Changes in internal controls.  There have been no significant changes in the
Company's internal controls or in other factors that could significantly  affect
