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.

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2003
(Unaudited)


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 and Use of Estimates

Basis of Presentation

Presentation. In the opinion of management, the unaudited consolidated
financial statements of the Company as of March 31, 2003 and for the three month
periods ended March 31, 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 (loss)
and net income (loss) 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 (loss) of the three month periods ended March 31,
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 (loss) and earnings 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:

Use of Estimates

As of March 31, 2003, the Company used an exchange rate of 3.0 pesos to
$1 to remeasure the peso-denominated monetary assets and liabilities of the
Company's Argentine subsidiaries.

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 interest rate swaps to minimize its 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 will
receive a fixed annual rate of 9-5/8 percent on $250 million notional amount and
will 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. As of March 31, 2003, the carrying value
of the Company's fair value hedges was an asset of $3.3 million.

As of March 31, 2003, the carrying value of the Company's long-term debt
in the accompanying Consolidated Balance Sheets included $29.5 million of
incremental liability attributable to unamortized deferred hedge gains realized
from fair value hedge agreements terminated during 2002 and 2001. The
amortization of these deferred hedge gains reduced the Company's reported
interest expense by $5.9 million and $2.9 million during the periods ended March
31, 2003 and 2002, respectively.

The following table sets forth the scheduled amortization of deferred
hedge gains on terminated fair value hedges that will be recognized as
reductions in 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, 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.

Oil. All material sales contracts governing the Company's oil production
have been tied directly or indirectly to the New York Mercantile Exchange
prices. The following table sets forth the Company's outstanding oil hedge
contracts and the weighted average NYMEX prices for those contracts as of March

Natural gas liquids prices. During the three month periods ended March
31, 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 in order
to mitigate the basis risk between NYMEX prices and actual index prices. The

Accumulated other comprehensive income ("AOCI") - deferred hedge gains
and losses, net. As of March 31, 2003 and December 31, 2002, "AOCI - deferred
hedge gains (losses), net" represented net deferred losses of $56.5 million and
net deferred gains of $9.6 million, respectively. The AOCI - deferred hedge
gains, net balance as of March 31, 2003 was comprised of $154.7 million of
unrealized deferred hedge losses on the effective portions of open commodity
cash flow hedges and $98.2 million of net deferred gains on terminated cash flow
hedges. The decrease in AOCI - deferred hedge gains, net during the three months
ended March 31, 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 gains and
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 and losses
on terminated cash flow hedges are fixed.

During the twelve month period ending March 31, 2004, the Company expects
to reclassify $103.1 million of net deferred losses associated with open cash
flow hedges and $64.1 million of net deferred gains on terminated cash flow
hedges from AOCI - deferred hedge gains, net to oil and gas revenue.

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 $30 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.

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)


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 March 31,
2003, the Company has settled $21.7 million of the original claim amounts. As of
March 31, 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 (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 net income
(loss) 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 months ended March 31, 2003 and 2002:

(a) Common stock options to purchase 1,377,519 shares and 4,998,951shares of
common stock were outstanding but not included in the computations of
diluted net income (loss) per share for the three months ended March 31,
2003 and 2002, respectively, because the exercise prices of the options
were greater than the average market price of the common shares and would
be anti-dilutive to the computations. In-the-money options representing
1,226,746 weighted average equivalent shares of common stock were not
included in the computation of diluted net loss per share for the three
months ended March 31, 2002, since they have a dilutive effect to net loss
per share.

(b) During the three months ended March 31, 2003, the Company issued 9,500
restricted shares of the Company's common stock to key employees of the
Company. 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.
Other foreign is primarily comprised of operations in Gabon, South Africa and
Tunisia.

The following table provides 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 first quarter
of 2003 was highlighted by favorable worldwide oil and North American gas
prices; growth in the Company's deepwater Gulf of Mexico sales volumes,
including reaching full production rates from the Canyon Express gas development
and first production during March 2003 from 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 announcement of a strategic joint
exploration agreement with Woodside Energy (USA) Inc. ("Woodside") for a
two-year drilling program over the shallow-water Texas shelf region of the Gulf
of Mexico; the Harrier field discovery, a Falcon field satellite that has been
sanctioned for development; a discovery in Alaska on three exploration wells
drilled on the Company's NW Kuparuk prospect which are currently being evaluated
for commercial viability; and the acquisition of the remaining 25 percent
working interest that the Company did not already own in the Falcon field, the
Harrier field and surrounding satellite prospects for $119.4 million (see Note C
of Notes to Consolidated Financial Statements included in "Item 1. Financial
Statements" for additional information regarding this acquisition).

The Company reported net income of $84.2 million ($.71 per diluted share)
for the three months ended March 31, 2003, including a $15.4 million ($.13 per
share) benefit from the cumulative effect of change in accounting principle
associated with the Company's adoption of Statement of Accounting Principles No.
143, "Accounting for Asset Retirement Obligations" ("SFAS 143") on January 1,
2003, as compared to a net loss of $2.0 million ($.02 per share) for the same
period in 2002. 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 $136.8
million for the three months ended March 31, 2003, representing an increase of
$86.8 million, or 174 percent, over the net cash provided by operating
activities of the same period in 2002. The increase in net cash provided by
operating activities was primarily a result of higher gas volumes and commodity
prices. During the three months ended March 31, 2003, the Company used its net
cash provided by operating activities, together with proceeds from the
disposition of assets and net borrowings under long-term debt to fund $252.8
million of additions to oil and gas properties.

Drilling Highlights

During the first three months of 2003, the Company completed its Falcon
field development, continued development activities at Devils Tower in the
deepwater Gulf of Mexico and Sable in South Africa, successfully drilled its
Harrier prospect, a Falcon satellite discovery, and drilled its first three
exploratory wells in Alaska, as referred to above. The Company also acquired the
25 percent working interest it did not already own in the Falcon field, the
Harrier field and surrounding satellite prospects during March of 2003. In
total, the Company incurred $285.7 million in capital expenditures during the
first quarter of 2003 including $77.4 million for development activities, $85.0
million for exploration activities and $123.3 million on acquisitions. Other
than the Falcon area acquisition, the majority of the Company's capital

expenditures was spent on drilling wells and fabricating infrastructure for the
Company's significant development projects. The following tables summarize the
Company's development drilling and exploration and extension drilling activities
for the three months ended March 31, 2003:

Domestic. The Company spent $227.6 million during the first three 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 $170.3 million of acquisition, drilling and seismic capital.
In the deepwater Gulf of Mexico, the Company has two major producing properties
and two major development projects that remain in progress as of March 31, 2003:

o Canyon Express - The TotalFinaElf-operated Aconcagua and the
Marathon-operated Camden Hills discoveries in Mississippi Canyon began
producing in September 2002. Associated with the start-up of this project,
several operational and mechanical difficulties were encountered which
delayed achieving full production rates of 110 to 120 MMcf of gas per day
until late January 2003.

o Falcon - The Company-operated Falcon field started producing in mid-March
2003. On March 28, 2003, the Company purchased the remaining 25 percent
working interest that the Company did not already own in 32 blocks in the
Falcon area, including the Falcon field, the Harrier field and surrounding
satellite prospects. 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 will be added, doubling its capacity to 400 MMcf of
gas per day. As is further discussed below, the Company expects first gas
production from Harrier field in late 2003 or early 2004 with combined
daily gas production from Falcon field and Harrier field expected to reach
275 MMcf per day.

PIONEER NATURAL RESOURCES COMPANY



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. Devils Tower production is scheduled
to begin in early 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.

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 expects to develop the field as a
single-well subsea tie-back to the Falcon field facilities which were
designed to be expandable. First production from the Harrier field is
anticipated in late 2003 or early 2004.

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
there later this year. If successful, these Falcon area prospects could also be
tied back to the Falcon field to utilize excess pipeline capacity. Additionally,
the Company has a multi-year inventory of prospects on the 32 blocks it holds 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 well under this joint
agreement was spud during the first quarter of 2003. The well is still in
progress and the results are expected to be known in May 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 one
well that was in progress at year end was completed and two wells were
successfully drilled during the first quarter of 2003. The Company spud an
extension well to the Pawnee field subsequent to quarter end and plans to drill
an additional three development wells and two extension wells during the
remainder of 2003.

Alaska. In Alaska, the Company spent $26.6 million during the first three
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 being evaluated to determine the commercial viability of the
Jurassic reservoir.

Permian Basin area. In the Permian Basin area, the Company spent $19.4
million during the first three months of 2003 primarily on development drilling
in the Spraberry oil trend where the Company plans to drill up to 150 wells
during 2003.

Mid-Continent area. In the Mid-Continent area, the Company spent $11.3
million during the first three months of 2003 primarily in the West Panhandle
field where the Company plans to drill up to 100 wells this year. The Company
also plans to drill up to 30 Hugoton wells later this year.

PIONEER NATURAL RESOURCES COMPANY


Argentina. In Argentina, the Company spent $10.0 million of acquisition,
drilling and seismic capital during the first three months of 2003. The majority
of costs was spent on extension and development drilling in the Neuquen Basin.

Canada. In Canada, the Company spent $37.3 million of acquisition,
drilling and seismic capital during the first three 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 successful and has been connected to a production pipeline, one well is
being evaluated and one well was unsuccessful.

Africa. In Africa, the Company spent $10.9 million of acquisition,
drilling and seismic capital during the first three months of 2003 in South
Africa, Tunisia and Gabon.

South Africa. In South Africa, the Company spent $6.0 million of capital
on the development of its Sable field that is expected to have first oil sales
during the third quarter. Development drilling is complete, the floating
production facility has been anchored into position in the field and upgrades
are still ongoing while the wells are tied in. Subsequent to quarter end, the
Company spud the first of its three planned exploratory wells in South Africa
during 2003.

Tunisia. In Tunisia, the Company spent $3.6 million of capital during the
first three months of 2003. The Company began development activities on its Adam
discovery which is expected to begin production during the second quarter
assuming government approval of the Adam concession. The Company drilled its
first operated well on its Jorf permit that was non-commercial, and spud the
first of two exploration wells on its Anadarko-operated Anaguid permit.

Gabon. In Gabon, the Company spent $1.3 million during the first quarter
of 2003. The Company is attempting to gain approval from the government of Gabon
for the development of the field under improved fiscal terms, due to the size
and complexity of the project.

Results of Operations

Oil and gas revenues. Revenues from oil and gas operations totaled $281.2
million for the three months ended March 31, 2003, compared to $165.5 million
for the same period in 2002. The increase in revenues is principally
attributable to increased gas production from the Canyon Express project and
initial production from the Falcon field in the deepwater Gulf of Mexico and to
commodity price increases.

The following table provides the Company's volumes and average reported
prices, including the results of hedging activities, for the three months ended
March 31, 2003 and 2002:

On a BOE basis, worldwide average daily production increased by 16
percent during the three months ended March 31, 2003, as compared to the same
period in 2002. During the first quarter of 2003, as compared to the first
quarter of 2002, worldwide oil production declined by eight percent; NGL
production increased by two percent; and gas production, augmented by a full
quarter of production from Canyon Express and initial production during March
from the Falcon field, increased by 36 percent. Per BOE average daily
production, on a first-quarter to first-quarter comparison, increased by 26
percent in the United States, while production in Argentina and Canada decreased
by eight percent and 12 percent, respectively.

Second quarter 2003 production volumes are expected to average 150,000
to 165,000 BOE per day. Gas production is expected to rise during the second
quarter as a result of the acquisition of an additional 25 percent working
interest in the Falcon field and realization of a full quarter of production
from the Falcon field. The range of expected daily production for the second
quarter of 2003 is expanded as a result of the production variability inherent
in bringing high volume, high impact wells into an otherwise relatively stable
production mix. Included in the second quarter guidance is a reduction in net
Falcon production volume reflecting the one-eighth royalty that becomes
effective if the average NYMEX gas price exceeds $4.10 per Mcf for 2003.

The Company is also widening the range of expected 2003 production to
55 million to 60 million BOE to reflect the Falcon royalty and the heightened
variability related to high volume wells. The Falcon field is performing better
than expected, and the Harrier field has the potential for early start-up, while
first oil sales from the Sable field are now expected in the third quarter. With
a full year of production from new fields brought on in 2003 and the addition of
at least two large fields in late 2003 or early2004, the Company expects 2004
production to range from 63 million to 75 million BOE.

As discussed above, oil and gas revenues for the quarter ended March 31,
2003 were positively impacted by commodity price increases. Comparing the first
quarter of 2003 to the same period in 2002, the Company's average worldwide oil

PIONEER NATURAL RESOURCES COMPANY


price increased 11 percent; the Company's average worldwide NGL price increased
105 percent; and the Company's average worldwide gas price 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 (swaps 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 first quarter of 2003, the Company's
commodity price hedges decreased oil and gas revenues by $50.4 million as
compared to $32.2 million of commodity price hedge gains during the same period
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 month periods ended March 31, 2003 and 2002.

During the second quarter of 2003, the Company has entered into the
following new oil and gas price hedges: (i) 3,000 Bbls per day of 2005 oil swap
contracts with average per Bbl fixed prices of $24.00, (ii) 50,000 MMBtu per day
of 2005 gas swap contracts with average per MMBtu fixed prices of $4.40, and
(iii) 10,000 MMBtu per day of 2004 gas collar contracts with average per MMBtu
fixed floor prices of $4.00 and fixed ceiling prices of $6.85. The Company also
terminated 2,000 Bbls per day of May through December 2003 oil swap contracts
with average per Bbl fixed prices of $25.00 and 1,000 Bbls per day of third and
fourth quarter 2003 oil swap contracts with average per Bbl fixed prices of
$24.00.

Gain (loss) on disposition of assets. During the three months ended March
31, 2003, the Company recorded $1.4 million of net gains on the disposition of
assets, as compared to $.1 million of net losses on the disposition of assets
during the same period in 2002.

Production costs. During the three month period ended March 31, 2003,
total production costs per BOE averaged $5.54, representing an increase of $.42
per BOE (eight percent), as compared to production costs per BOE of $5.12 during
the same period in 2002, and representing an increase of $1.01 per BOE (22
percent), as compared to production costs per BOE of $4.53 during the fourth
quarter 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 first quarter of
2003, as compared to the first quarter of 2002, is primarily due to increases in
production taxes and field fuel expenses as a result of higher gas prices,
partially offset by decreases in lease operating expenses, ad valorem taxes and
workover costs. As compared to the fourth quarter of 2002, the increase in
production costs per BOE during the first quarter of 2003 was due to increases
in production taxes and field fuel expenses as a result of higher gas prices and
to higher lease operating expenses associated with the start-up of the Company's
deepwater Gulf of Mexico Canyon Express production.

Depletion, depreciation and amortization expense. The Company's total
depletion, depreciation and amortization expense per BOE was $6.06 and $5.06 for
the three month periods ended March 31, 2003 and 2002, respectively. Depletion
expense per BOE, the largest component of depletion, depreciation and
amortization, increased to $5.86 per BOE during the three months ended March 31,
2003, as compared to $4.84 per BOE during the same period in 2002, primarily due
to increases in higher cost-basis deepwater Gulf of Mexico production volumes.

The Company expects second quarter 2003 depletion, depreciation and
amortization expense to average $6.50 to $6.90 per BOE.

Exploration and abandonments/geological and geophysical costs.
Exploration and abandonments/geological and geophysical costs were $35.9 million
during the three months ended March 31, 2003, as compared to $21.1 million
during the same period in 2002. During the first quarter of 2003, the Company
completed and evaluated 56 exploration/extension wells, 26 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 month periods ended March 31, 2003 and 2002:

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


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

General and administrative expense. General and administrative expense
for the three month periods ended March 31, 2003 and 2002 was $15.5 million and
$11.9 million, respectively. The $3.6 million increase in general and
administrative expense during the first quarter of 2003 as compared to the same
period of 2002 is primarily due to increases in performance related compensation
costs.

The Company expects second quarter 2003 general and administrative
expense to be approximately $14 million.

Accretion of discount on asset retirement obligations. During the three
months ended March 31, 2003, accretion of discount on asset retirement
obligations was $1.1 million. 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
expense during the three months ended March 31, 2002 includes $651 thousand 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.

PIONEER NATURAL RESOURCES COMPANY


Interest expense. Interest expense was $22.5 million for the quarter
ended March 31, 2003, as compared to $26.3 million for the same period in 2002.
The $3.8 million (or 14 percent) decrease in interest expense during the first
quarter of 2003, as compared to the first quarter of 2002, is primarily due to a
$3.9 million increase in interest rate hedge gains, including amortization of
deferred hedge gains; interest rate 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; and lower underlying market rates of interest.

The Company expects second quarter 2003 interest expense to be $24
million to $26 million, including accretion of discount on asset retirement
obligations.

Other expenses. Other expenses for the three months ended March 31, 2003
and 2002 were $5.2 million and $8.3 million, respectively. The decrease in other
expense is primarily attributable to a $5.4 million decrease in the
remeasurement of Argentine peso-denominated net monetary assets and a $2.2
million improvement in Canadian gas marketing margins; partially offset by a
$1.8 million increase in commodity hedge ineffectiveness, a $1.0 million
increase in realized foreign exchange losses and other expense increases.

Income tax provision (benefit). During the three month periods ended
March 31, 2003, the Company recognized an income tax provision of $2.3 million,
principally associated with Argentine taxable income, as compared to an income
tax benefit of $.4 million during the three months ended March 31, 2002.

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's deferred tax valuation reserves are reduced when the Company's
financial results establish that it is more likely than not that deferred tax
assets previously reserved will be used prior to their expiration.

During the second quarter of 2003, the Company estimates that its income
tax provision will approximate $5 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, in
accordance with the provisions of SFAS 143, recognized a $15.4 million, or $.13
per share, 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 do 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 months ended March 31, 2003 and 2002
totaled $252.8 million and $88.3 million, respectively. The Company's first
quarter 2003 additions to oil and gas properties were funded by $136.8 million
of net cash provided by operating activities, $15.6 million of proceeds from
disposition of assets and borrowings under long-term debt. The Company's first
quarter 2002 expenditures were internally funded by $50.0 million of net cash
provided by operating activities and a portion of the Company's $51.6 million of
proceeds from disposition of assets.


31




PIONEER NATURAL RESOURCES COMPANY


The Company has increased its capital budget for 2003 to approximately
$650 million, including the first quarter 2003 acquisition of the remaining 25
percent working interest in Falcon field, Harrier field and surrounding
prospects and the additional 2003 exploration and development costs attributable
to those interests.

Contractual obligations. The Company's contractual obligations include
long-term debt, operating leases, Btu swap agreements, terminated commodity
hedges and other contracts. During the three months ended March 31, 2003, the
Company increased its long-term debt by $99.1 million, reduced its obligations
under the Btu swap agreements by $1.7 million and settled terminated commodity
hedge obligations for $198 thousand. Contractual obligations for which the
ultimate settlement amounts are not fixed and determinable include derivative
contracts that are sensitive to future changes in commodity prices, currency
exchange rates and interest rates. 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 three months
ended March 31, 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 months ended March 31, 2003 and 2002 were $136.8 million and $50.0
million, respectively. The increase in net cash provided by operating activities
during the three months ended March 31, 2003, as compared to the same period in
2002, is primarily due to higher gas sales volumes and to higher commodity
prices.

Financing activities. Net cash provided by financing activities during
the three months ended March 31, 2003 were $100.6 million as compared to net
cash used in financing activities during the three months ended March 31, 2002
of $8.1 million. During the three months ended March 31, 2003, the primary
source of net cash provided by financing activities was borrowings under the
Company's $575 million corporate credit facility (the "Credit Facility"). The
first quarter 2003 borrowings under the Credit Facility were used to fund the
$113 million cash payment 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 January 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 obligate the Company to pay the counterparties
a variable annual rate equal to the six-month London Interbank Offered Rate
("LIBOR") plus 566.4 basis points; obligate the counterparties to pay the
Company a fixed rate of 9-5/8 percent; and, provide for a notional debt amount
of $250 million. The interest rate swap contracts mature in 2010.

Outstanding borrowings under the Credit Facility totaled $365 million as
of March 31, 2003. The weighted average interest rate on the Company's
indebtedness for the three months ended March 31, 2003 was 5.11 percent as
compared to 6.11 percent for the three months ended March 31, 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 months ended March 31, 2003 and 2002,
proceeds from the sale of assets totaled $15.6 million and $51.6 million,



32




PIONEER NATURAL RESOURCES COMPANY


respectively. The Company's 2003 asset divestitures were primarily comprised of
shallow-water Gulf of Mexico shelf prospects, in which a partial interest was
sold to Woodside. The Company's 2002 asset divestitures were primarily comprised
of hedge derivatives.

Book capitalization and liquidity. Total debt was $1.8 billion as of
March 31, 2003, as compared to total debt of $1.7 billion on December 31, 2002.
The Company's total book capitalization at March 31, 2003 was $3.2 billion,
consisting of total debt of $1.8 billion and stockholders' equity of $1.4
billion. Consequently, the Company's debt to total capitalization increased to
55.6 percent at March 31, 2003 from 54.6 percent at December 31, 2002. The
Company's ratio of current assets to current liabilities was .52 at March 31,
2003 and .54 at December 31, 2002. Including $28.8 million of undrawn and
outstanding letters of credit, the Company had $181.2 million of unused
borrowing capacity available under its Credit Facility as of March 31, 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 balance.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The following quantitative and qualitative disclosures about market risk
are supplementary to the quantitative and qualitative disclosures provided in
the Company's Annual Report on Form 10-K for the fiscal year ended December 31,

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, in
U.S. dollar equivalent amounts, about the financial instruments that the Company
was a party to as of March 31, 2003 and that are sensitive to changes in
interest rates. For debt obligations, the table presents maturities by expected
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
March 31, 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
notes. Under the terms of the interest rate swap contracts, the Company will
receive a fixed annual rate of 9-5/8 percent on $250 million notional amount and
will 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. The accompanying table presents the interest rate swap agreement

(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.
The Company considers these basis swaps as part of the associated swap and
option contracts and, accordingly, the effects of the basis swaps have been
presented together with the associated contracts.

(a) Evaluation of disclosure controls and procedures. Within 90 days prior to
the filing date of this Report, the Company's principal executive officer
("CEO") and principal financial officer ("CFO") carried out an evaluation of the
effectiveness of the Company's disclosure controls and procedures. Based on
those evaluations, the Company's CEO and CFO believe (i) that the Company's
disclosure controls and procedures are designed to ensure that information
required to be disclosed by the Company in the reports it files under the
Securities Exchange Act of 1934 is recorded, processed, summarized and reported
within the time periods specified in the SEC's rules and forms and that such
information is accumulated and communicated to the Company's management,
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
the Company's internal controls subsequent to the evaluation referred to in Item
4. (a), above, nor have there been any corrective actions with regard to
significant deficiencies or material weaknesses.
