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.

PIONEER NATURAL RESOURCES COMPANY

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


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.

are net of $1.7 million and $5.0 million of tax benefits, respectively. No
tax benefits were recognized for the 2002 compensation expense. See Note C
for additional information regarding the Company's income taxes in the
United States.



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.

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2003

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

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

15

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
deferred hedge gains (losses), net of tax" to oil and gas revenue and income tax
(provision) benefit.

The following table sets forth the scheduled reclassifications of pretax
net deferred hedge gains and losses on terminated cash flow hedges as of
September 30, 2003 that will be recognized in the Company's future oil and gas
revenue:

The net deferred commodity hedge gains and losses shown in the table above
include the following gains and losses for which cash settlements have been
deferred until the indicated future periods: (i) $22.8 million of net deferred
losses due during the fourth quarter of 2003, (ii) $1.2 million of net deferred
losses due during 2004 and (iii) $209 thousand of net deferred gains to be
received during 2005.

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

NOTE G. 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

16




PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)


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:

(a) Common stock options to purchase 1,179,766 shares and 1,868,588 shares of
common stock were outstanding but not included in the computations of
diluted income (loss) before cumulative effect of change in accounting
principle per share for the three month periods ended September 30, 2003
and 2002, respectively, and common stock options to purchase 1,308,582
shares and 2,024,455 shares of common stock were outstanding but not
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.

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
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 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


24




PIONEER NATURAL RESOURCES COMPANY


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.

------ ------ ------ ------
Total production costs........ $ 4.78 $ 4.66 $ 5.00 $ 4.92
====== ====== ====== ======


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.

The Company expects fourth quarter 2003 exploration and abandonment
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.

PIONEER NATURAL RESOURCES COMPANY


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.

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.

PIONEER NATURAL RESOURCES COMPANY


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.

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

$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.

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.

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