          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;"MBbl"  means
one thousand  Bbls;  "MBOE" means one  thousand  BOEs;  "Mcf" means one thousand
cubic feet and is a measure of natural  gas  volume;  "MMBtu"  means one million
Btus;  "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 ("Pioneer" or the "Company") 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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  June 30, 2004
                                   (Unaudited)


NOTE A.     Organization and Nature of Operations

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

NOTE B.     Basis of Presentation

     Presentation.  In the opinion of  management,  the  unaudited  consolidated
financial  statements  of the  Company as of June 30, 2004 and for the three and
six months ended June 30, 2004 and 2003 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
("GAAP") 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 as of and for the year ended December 31, 2003.

     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.

     The  adoption of SFAS 143 resulted in a January 1, 2003  cumulative  effect
adjustment  to record a gain of $15.4  million,  net of $1.3 million of deferred
tax, as a cumulative  effect  adjustment of a change in accounting  principle in
the Company's Consolidated  Statements of Operations.  See Note F for additional
information regarding the Company's asset retirement obligations.

     Inventories.  Inventories  are comprised of $20.3 million and $15.3 million
of lease and well  equipment and $1.5 million and $2.2 million of commodities as
of June 30, 2004 and December 31, 2003,  respectively.  Lease and well equipment
inventories  are net of lower of cost or market  allowances of $.6 million as of
June 30, 2004 and December 31, 2003.

     Stock-based  compensation.  The Company has a long-term incentive plan (the
"Long-Term   Incentive  Plan")  under  which  the  Company  grants   stock-based
compensation.  The Company accounts for stock-based  compensation  granted under
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.  The  Company did not grant any stock
options  during the six months  ended June 30,  2004.  Stock-based  compensation
expense associated with option grants was not recognized in the determination of
the Company's net income during the three and six months ended June 30, 2004 and
2003, as all options  granted under the  Long-Term  Incentive  Plan 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.

     expense  included in net income is net of tax  benefits of $1.1 million and
     $1.8 million,  respectively.  Similarly,  stock-based  compensation expense
     determined  under the fair value based  method for the three and six months
     ended  June  30,  2004 is net of tax  benefits  of $2.0  million  and  $3.8
     million,  respectively.  No tax benefits were  recognized  for  stock-based
     compensation  expense  during the three and six months ended June 30, 2003.
     See Note C for additional information regarding the Company's income taxes.
</FN>


NOTE C.     Income Taxes

     The Company  accounts for income taxes in accordance with the provisions of
Statement of Financial  Accounting  Standards  No. 109,  "Accounting  for Income
Taxes" ("SFAS 109"). SFAS 109 requires that the Company  continually assess both
positive and negative  evidence to determine  whether it is more likely than not
that deferred tax assets can be realized  prior to their  expiration.  From 1998
until 2003, the Company  maintained a valuation  allowance  against a portion of
its deferred tax asset position in the United  States.  During the third quarter
of 2003, the Company concluded that it was more likely than not that it would be
able to realize its gross  deferred  tax asset  position  in the United  States.
Accordingly, the Company reversed its valuation allowances in the United States.
As a result of the reversal of the  valuation  allowances  against the Company's
United States  deferred tax assets,  the Company's  effective tax rate on future
earnings in the United States will approximate statutory rates.

     Pioneer will continue to monitor Company-specific, oil and gas industry and
worldwide economic factors and will assess the likelihood that the Company's net
operating  loss  carryforwards  and other  deferred tax attributes in the United
States and foreign tax jurisdictions will be utilized prior to their expiration.
As of June 30, 2004, the Company's  valuation  allowances related to foreign tax
jurisdictions were $102.2 million.

NOTE D.     Long-term Debt

     During June 2004,  the Company  entered into a first  amendment (the "First
Amendment")  to its $700 million,  five-year  revolving  credit  agreement  (the
"Revolving  Credit  Agreement").  As a result  of the First  Amendment,  Pioneer
Natural Resources USA, Inc., a wholly-owned  subsidiary of the Company ("Pioneer
USA"),  is no  longer  a  guarantor  of  the  Revolving  Credit  Agreement.  The
indentures  of the  Company's  senior notes  provide for  subsidiary  guarantees
equivalent to any such guarantees provided under the Revolving Credit Agreement.
Accordingly,  the First Amendment also has the effect of removing Pioneer USA as
a guarantor of the Company's senior notes.

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 March 2004,  the Company  entered into interest rate swap contracts on an
aggregate  $150  million  notional  amount to hedge the fair  value of its 7-1/2
percent senior notes.  The terms of the interest rate swap  contracts  match the
scheduled maturity of the hedged senior notes, require the counterparties to pay
the Company a 7-1/2 percent  fixed annual  interest rate and require the Company
to pay the  counterparties  variable annual interest rates equal to the periodic
six-month  LIBOR plus a weighted  average annual margin of 3.71 percent.  During
April  2004,  the  Company  entered  into  interest  rate swap  contracts  on an
aggregate  $150  million  notional  amount to hedge the fair  value of its 9-5/8
percent  senior  notes.  The terms of the new 9-5/8  percent  interest rate swap
contracts  match the  scheduled  maturity of the senior  notes which they hedge,
require the  counterparties  to pay the  Company a 9-5/8  percent  fixed  annual
interest rate and require the Company to pay the counterparties  variable annual
interest  rates equal to the periodic  six-month  LIBOR plus a weighted  average
annual margin of 5.66 percent.  During  February 2003, the Company  entered into
similar  interest rate swap contracts which were terminated  during May 2003 for
$11.4 million of cash  proceeds.  As of June 30, 2004,  the  aggregate  carrying
value of the Company's  open fair value hedges was a liability of $14.9 million.
Settlements of open fair value hedges reduced the Company's  interest expense by
$1.8 million and $1.1 million during the three-month periods ended June 30, 2004
and  2003,  respectively,  and by $2.0  million  and  $1.9  million  during  the
six-month periods then ended, respectively.

     As of June 30, 2004, the carrying value of the Company's  long-term debt in
the  accompanying   Consolidated   Balance  Sheets  included  $14.0  million  of
incremental   carrying  value  attributable  to  net  deferred  hedge  gains  on
terminated  interest  rate swaps that are being  amortized as net  reductions to
interest  expense  over the original  terms of the  terminated  agreements.  The

     The terms of the fair value  hedge  agreements  described  above  perfectly
matched the terms of the hedged  senior  notes.  The Company did not exclude any
component of the interest  rate swaps' gains or losses from the  measurement  of
hedge  effectiveness.  Accordingly,  the  Company  did  not  realize  any  hedge
ineffectiveness  associated  with its fair value hedges during the three and six
month periods ended June 30, 2004 or 2003.

     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, from time to time,  utilized  interest
rate contracts to reduce the effect of interest rate volatility on the Company's
indebtedness  and forward currency  exchange  agreements to reduce the effect of
U.S. dollar to Canadian dollar exchange rate volatility.

     Oil prices.  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 June 30, 2004:

     Natural gas liquids prices.  During the three and six months ended June 30,
2004 and 2003,  the  Company did not enter into any NGL hedge  contracts.  There
were no outstanding NGL hedge contracts at June 30, 2004.

     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,  or
based on NYMEX  prices if NYMEX  prices  are  highly  correlated  with the index
price.  The  following  table sets  forth the  Company's  outstanding  gas hedge
contracts and the weighted  average index prices for those  contracts as of June
30, 2004:

     Interest rate.  During June 2004, the Company  entered into costless collar
contracts and  designated  the  contracts as cash flow hedges of the  forecasted
interest rate risk  attributable to the yield on the benchmark 4.75 percent U.S.
Treasury Notes due May 15, 2014 (the "U.S. Treasuries"). The terms of the collar
contracts  fixed  the  annual  yield on $250  million  notional  amount  of U.S.
Treasuries  within a yield  collar  having a ceiling  rate of 4.70 percent and a
floor rate of 4.65 percent.  The yield on the U.S. Treasuries as of July 7, 2004
was the benchmark rate used to determine the coupon rate on the Company's  5-7/8
percent  senior notes due July 15,  2016,  which were issued on July 15, 2004 in
exchange for portions of three series of the Company's outstanding senior notes.
The Company did not realize any  ineffectiveness in connection with the costless
collar  contracts  during the three months  ended June 30, 2004.  See Note L for
information regarding the July 15, 2004 debt exchange.

     Hedge  ineffectiveness.  During the three-month periods ended June 30, 2004
and  2003,  the  Company  recognized  other  expense  of $1.8  million  and $503
thousand,  respectively,  related to the  ineffective  portions of its cash flow
hedging instruments.  During the six-month periods ended June 30, 2004 and 2003,
the  Company  recognized  other  expense  of  $1.9  million  and  $2.3  million,
respectively,  related  to the  ineffective  portions  of its cash flow  hedging
instruments.

     Accumulated other comprehensive  income (loss) - net deferred hedge losses,
net of tax ("AOCI - Hedging"). As of June 30, 2004 and December 31, 2003, AOCI -
Hedging  represented  net deferred  losses of $198.3 million and $104.1 million,
respectively.  The AOCI - Hedging  balance as of June 30, 2004 was  comprised of
$329.4  million of net deferred  losses on the  effective  portions of open cash
flow hedges,  $23.2 million of net deferred gains on terminated cash flow hedges
and $107.9 million of associated net deferred tax benefits. The increase in AOCI
- - Hedging  during the six months ended June 30, 2004 was primarily  attributable
to  increases  in future  commodity  prices  relative  to the  commodity  prices
stipulated in the hedge contracts,  partially offset by the  reclassification of
net deferred hedge losses to net income as  derivatives  matured by their terms.
The net deferred 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 contracts or terminated prior to settlement. The net deferred gains
on terminated cash flow hedges are fixed.

     During the twelve months ending June 30, 2005,  based on current  estimates
of future commodity prices,  the Company expects to reclassify $175.9 million of
net deferred  losses  associated with open cash flow hedges and $22.6 million of
net deferred gains on terminated cash flow hedges from AOCI - Hedging to oil and
gas revenues. The Company also expects to reclassify approximately $64.2 million
of net deferred  income tax benefits  during the twelve  months  ending June 30,
2005 from AOCI - Hedging to income tax provision.

     The  following  table  sets  forth,  as of June  30,  2004,  the  scheduled
amortization  of net deferred gains on terminated  cash flow hedges that will be
recognized as increases to the Company's future oil and gas revenues:

NOTE F.     Asset Retirement Obligations

     As referred to in Note B, the Company  adopted the provision 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  does not provide for a market risk  premium  associated  with asset
retirement  obligations  because a reliable  estimate cannot be determined.  The
Company has no assets that are legally restricted for purposes of settling asset

NOTE H.     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

                        PIONEER NATURAL RESOURCES COMPANY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  June 30, 2004
                                   (Unaudited)


Company's Satanta gas plant. The case was relatively inactive for several years.
In early 2000,  the plaintiffs  amended their  pleadings and it now contains two
material claims.  First, the plaintiffs assert that they were improperly charged
expenses  (primarily field compression),  which are a "cost of production",  and
for which  plaintiffs,  as royalty  owners,  are not  responsible.  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  (both  for  periods  covered  by the  lawsuit  and from the last date
covered by the lawsuit to the present - because  the  deductions  continue to be
taken and the plaintiffs  continue to be paid for a royalty share of the helium)
could  reach $67  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  other
agreements, and intends to vigorously defend itself.

     The  Company  does not  believe  the costs it has  deducted  are a "cost of
production".  The costs being  deducted are post  production  costs  incurred to
transport the gas to the Company's  Satanta gas plant for processing,  where the
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 and  with  the  parties'
agreements.

     The Company has also vigorously  defended against the 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. 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 the FERC
with respect to that  portion of the refund  associated  with (i)  nonrecoupable
royalties,  (ii)  nonrecoupable  Kansas  property taxes based, in part, upon the
higher  prices  collected and (iii)  interest for all periods.  On September 10,
1997,  the FERC denied this  request,  and on October 10, 1997,  the Company and
other  producers  filed a request  for  rehearing.  Pipelines  were given  until
November  10, 1997 to file claims on refunds  sought from  producers  and refund
claims  totaling  approximately  $30.2  million  were made  against the Company.
Through June 30,  2004,  the Company has settled  $21.6  million of the original
claim  amounts.  As of June 30, 2004 and December  31, 2003,  the Company had on
deposit $10.7 million,  including accrued interest, in an escrow account and had
a  corresponding  obligation  for the remaining  claim recorded in other current
liabilities in the accompanying Consolidated Balance Sheets as of June 30, 2004.
The Company believes that the accrued  obligations will be sufficient to resolve
the remaining claims.

NOTE I.     Income Per Share Before Cumulative Effect of Change in Accounting
            Principle

     Basic income per share  before  cumulative  effect of change in  accounting
principle is computed by dividing income before  cumulative  effect of change in
accounting principle by the weighted average number of common shares outstanding
for the period.  The  computation of diluted 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 shares  outstanding for the three and six months ended June 30, 2004 and
2003:

NOTE K.     Evergreen Merger

     Proposed merger with Evergreen Resources,  Inc. On May 3, 2004, the Company
entered  into an  Agreement  and Plan of Merger (the  "Merger  Agreement")  with
Evergreen  Resources,  Inc.  ("Evergreen").   Evergreen  is  a  publicly  traded
independent oil and gas company primarily engaged in the operation, development,
production, exploration and acquisition of North American unconventional natural
gas. Evergreen is based in Denver, Colorado and is one of the leading developers
of coal bed methane  reserves in the United States.  Evergreen's  operations are
principally  focused on developing  and  expanding its coal bed methane  project
located  in the Raton  Basin in  southern  Colorado  and its  recently  acquired
producing properties in the Piceance Basin in western Colorado, the Uintah Basin
in eastern Utah and the Western Canada  Sedimentary  Basin. The Merger Agreement
provides for a merger by which  Evergreen will become a wholly-owned  subsidiary
of Pioneer (the "Proposed Merger").

     In  accordance  with the  Merger  Agreement,  holders of  approximately  44
million  shares of  Evergreen  common  stock  will have the right to  receive an
aggregate  of  approximately  25 million  shares of Pioneer  common  stock (with
related  stockholders rights) and a total of approximately $850 million in cash.
This  represents a price per Evergreen  share of $39.00 (based on Pioneer's last
reported  sale price on May 3, 2004 of $33.52 per share).  Holders of  Evergreen
common  stock will have the option to elect among  three types of  consideration
for a share of  Evergreen  common  stock:  (1) 1.1635  shares of Pioneer  common
stock;  (2) $39.00 cash; or (3) .58175 shares of Pioneer common stock and $19.50
in cash. Evergreen  stockholders who do not make an election will receive .58175
shares of Pioneer  common  stock and  $19.50 in cash per  Evergreen  share.  All
holders of unvested  restricted  stock under  Evergreen's  stock-based  employee
plans will be deemed to have elected to receive  Pioneer  common stock.  Holders
who elect all stock consideration or all cash consideration  (other than holders
of unvested  restricted  stock) will be subject to  allocation  of the stock and
cash so that the  aggregate  amounts  of stock and cash will be limited to those
amounts set forth in the first sentence of this paragraph.

     In  addition,  Evergreen  is seeking to sell its Kansas  assets  before the
closing  date of the Proposed  Merger.  Evergreen  stockholders  will receive an
additional  cash payment  equal to the sum of (i) $.35 per share  (approximately
$15  million) as  consideration  from Pioneer for the Kansas  properties  in the
Proposed Merger;  plus (ii) an amount per share equal to a pro rata share of the
net proceeds in excess of $15 million from the sale of the Kansas properties, if
any,  to a third  party that  closes  before the  closing  date of the  Proposed
Merger.

     The Company filed with the SEC a registration statement on Form S-4 on June
14,  2004  relating  to the shares of Pioneer  common  stock to be issued in the
Proposed Merger. A portion of such  registration  statement  constituted a joint
proxy  statement/prospectus  to be submitted to the  stockholders of Evergreen's
common stock and the Company's  common stock for special  meetings to be held by
each  company's  stockholders  in  connection  with the Proposed  Merger.  It is
expected  that  such  joint  proxy  statement/prospectus  will be  mailed to all
stockholders  during  August 2004,  and that such meeting will be held,  and the
Proposed Merger will be consummated,  in September 2004.  Since meetings of both
Evergreen's  and  Pioneer's  stockholders  are required in  connection  with the
Proposed Merger,  in addition to a number of other  conditions,  there can be no
assurance that the Proposed Merger will occur.

NOTE L.     Subsequent Events

     On July 15, 2004, the Company  accepted tenders to exchange $117.9 million,
$275.1 million and $133.8 million in principal amount of its 8 1/4% Senior Notes
due 2007,  9-5/8% Senior Notes due April 1, 2010 (the "9-5/8%  Notes") and 7.50%
Senior Notes due 2012 (the "7.50%  Notes"),  respectively,  for a like principal
amount of a new series of 5.875%  Senior  Notes due 2016 (the "New  Notes")  and
cash.  The aggregate  exchange  price paid to the holders of the tendered  notes
exceeded their aggregate  principal  balances by $109.0  million.  In accordance
with Financial  Accounting  Standards  Board Emerging Issues Task Force Abstract

                       PIONEER NATURAL RESOURCES COMPANY


     The Company  recorded net income of $69.7 million ($.58 per diluted  share)
and $129.9  million ($1.08 per diluted share) for the three and six months ended
June 30, 2004,  respectively,  as compared to net income of $77.2  million ($.65
per diluted  share) and $161.4 million  ($1.36 per diluted  share),  including a
$15.4  million  benefit  from the  cumulative  effect of  change  in  accounting
principle,  net of tax,  associated  with the Company's  adoption of SFAS 143 on
January 1, 2003, for the same respective periods of 2003. See Note F of Notes to
Consolidated Financial Statements included in "Item 1. Financial Statements" for
additional  information  regarding the Company's asset  retirement  obligations.
Income  before  income  taxes and  cumulative  effect  of  change in  accounting
principle increased by $41.6 million (52 percent) and $70.5 million (47 percent)
during the three and six month  periods  ended June 30,  2004 as compared to the
same respective periods ended June 30, 2003.  However,  primarily as a result of
the  reversal  of the  Company's  United  States  deferred  tax asset  valuation
allowances  during the third quarter of 2003, the Company's income tax provision
increased  by $49.1  million  and $86.6  million  during the three and six month
periods  ended June 30, 2004 as compared to the same  respective  periods  ended
June 30, 2003.

     The Company's net cash provided by operating  activities was $264.7 million
and  $518.3  million  for  the  three  and  six  months  ended  June  30,  2004,
respectively,  representing  increases  of $74.8  million  and  $194.1  million,
respectively,  as  compared to $189.9  million  and $324.2  million for the same
respective  periods in 2003.  During the three months  ended June 30, 2004,  the
Company  used its net cash  provided  by  operating  activities  to fund  $183.6
million  of  additions  to oil and gas  properties,  to repay  $46.0  million of
long-term  debt,  to purchase  $9.7 million of treasury  stock and to fund $12.0
million of dividends on common stock. During the six months ended June 30, 2004,
the Company used its net cash  provided by operating  activities  to fund $350.8
million of  additions  to oil and gas  properties,  to repay  $136.0  million of
long-term  debt, to purchase  $15.3 million of treasury  stock and to fund $12.0
million of dividends on common stock.

Proposed Merger with Evergreen Resources, Inc.

     Evergreen is a publicly traded  independent  oil and gas company  primarily
engaged in the operation, development,  production,  exploration and acquisition
of  North  American  unconventional  natural  gas.  Evergreen's  operations  are
principally  focused on developing  and  expanding its coal bed methane  project
located  in the Raton  Basin in  southern  Colorado  and its  recently  acquired
producing properties in the Piceance Basin in western Colorado, the Uintah Basin
in eastern Utah and the Western Canada  Sedimentary  Basin. The Merger Agreement
provides for a merger by which  Evergreen will become a wholly-owned  subsidiary
of Pioneer.

     Proposed purchase terms. In accordance with the Merger  Agreement,  holders
of approximately 44 million shares of Evergreen common stock will have the right
to receive an aggregate of  approximately  25 million  shares of Pioneer  common
stock  (with  related  stockholders  rights) and a total of  approximately  $850
million in cash. This represents a price per Evergreen share of $39.00 (based on
Pioneer's last reported sale price on May 3, 2004 of $33.52 per share).  Holders
of  Evergreen  common  stock will have the option to elect  among three types of
consideration  for a share of  Evergreen  common  stock:  (1)  1.1635  shares of
Pioneer common stock;  (2) $39.00 cash;  or (3)  .58175 shares of Pioneer common
stock and $19.50 in cash.  Evergreen  stockholders  who do not make an  election
will  receive  .58175  shares of  Pioneer  common  stock and  $19.50 in cash per
Evergreen  share.  All holders of unvested  restricted  stock under  Evergreen's
stock-based  employee  plans will be deemed to have  elected to receive  Pioneer
common  stock.   Holders  who  elect  all  stock   consideration   or  all  cash
consideration  (other than holders of unvested restricted stock) will be subject
to allocation  of the stock and cash so that the aggregate  amounts of stock and
cash will be limited to those  amounts  set forth in the first  sentence of this
paragraph.

     In  addition,  Evergreen  is seeking to sell its Kansas  assets  before the
closing  date of the Proposed  Merger.  Evergreen  stockholders  will receive an
additional  cash payment  equal to the sum of (i) $.35 per share  (approximately
$15  million) as  consideration  from Pioneer for the Kansas  properties  in the
Proposed Merger;  plus (ii) an amount per share equal to a pro rata share of the
net  proceeds  in excess of $15  million  from the sale,  if any,  of the Kansas
properties  to a third party that closes before the closing date of the Proposed
Merger.

     Strategic  rationale.  Pioneer's  business  strategy for  sustaining  above
average  growth  in per  share  value is  predicated  on the  leveraging  of its
long-lived  foundation  assets.  Those  foundation  assets  generate  dependable
operating  cash flows while  requiring  relatively  low  amounts of  maintenance
capital.  As a result,  the Company's  foundation assets provide free cash flows
(i.e., operating cash flows after maintenance capital expenditures) that finance


                                       23




                        PIONEER NATURAL RESOURCES COMPANY


investments   in   high-impact,    high-return   exploration   and   acquisition
opportunities.  The Proposed  Merger  offers an  opportunity  for the Company to
rebalance its portfolio of long-lived  foundation  assets by adding  Evergreen's
long-lived  onshore  producing asset base and significant  low-risk  development
drilling  opportunities.  Additionally,  the  Company's  decision  to pursue the
Proposed  Merger  was  positively  impacted  by  the  compatible  technical  and
corporate  cultures of Pioneer and Evergreen,  Evergreen's  substantial  acreage
position  in key  growth  basins  of the  United  States  Rockies  area  and the
opportunity to leverage Evergreen's  technical expertise in the area of coal bed
methane operations.

     Liquidity and capital  structure.  The completion of the Proposed Merger is
expected to result in a short-term increase of approximately $1.2 billion in the
Company's  long-term  debt,  comprised  of the  funding of $850  million in cash
consideration  paid,  approximately  $8 million of transaction  costs associated
with the  Proposed  Merger,  approximately  $15 million to fund the  purchase of
Evergreen's  Kansas  assets if Evergreen is unable to sell those assets prior to
closing the Proposed  Merger and the assumption of (i) $100 million of Evergreen
4.75 percent convertible senior subordinated bonds that are callable in December
2006 and (ii) $200 million of Evergreen 5.875 percent senior  subordinated bonds
due in 2012.  The  Company  intends  to finance  the cash costs of the  Proposed
Merger  with a new $900  million,  364-day  senior  unsecured  revolving  credit
facility,  the terms of which will  essentially  mirror  those of the  Company's
Revolving Credit  Agreement,  including the bearing of a variable annual rate of
interest  equal to the six-month  LIBOR rate plus a 75 basis point LIBOR margin.
The  completion  of the Proposed  Merger is expected to increase  the  Company's
stockholders' equity by approximately $900 million as a result of the associated
issuance of approximately 25 million shares of Pioneer common stock.

     The  Company  has  targeted  a ratio of debt to book  capitalization  of 40
percent  or less by the end of 2005.  To achieve  this  target,  the  respective
companies have implemented an aggressive  commodity hedging program of Pioneer's
and  Evergreen's  2004 and 2005  forecasted  oil and gas  production,  utilizing
commodity swap contracts  entered into with highly-rated  financial  institution
counterparties. Consistent with this program, Evergreen has hedged approximately
75 percent of its remaining  forecasted 2004 and forecasted 2005 gas production.
The Company has hedged approximately 35 percent of its remaining forecasted 2004
worldwide liquids and 50 percent of its remaining forecasted 2004 North American
gas production  and  approximately  35 percent of its forecasted  2005 worldwide
liquids and North American gas  production.  See Note E of Notes to Consolidated
Financial  Statements  included in "Item 1. Financial  Statements"  and "Item 3.
Quantitative and Qualitative Disclosures About Market Risk" for more information
regarding the Company's commodity hedge positions.

     Regulatory  and  shareholders  approvals.  The Company filed with the SEC a
registration  statement  on Form S-4 on June 14, 2004  relating to the shares of
Pioneer  common  stock to be issued in the  Proposed  Merger.  A portion of such
registration  statement  constituted  a joint proxy  statement/prospectus  to be
submitted to the  stockholders  of  Evergreen's  common stock and the  Company's
common stock for special  meetings to be held by each company's  stockholders in
connection  with the  Proposed  Merger.  It is  expected  that such joint  proxy
statement/prospectus  will be mailed to all stockholders during August 2004, and
that such meeting will be held,  and the Proposed Merger will be consummated, in
September 2004.  Since meetings of both  Evergreen's and Pioneer's  stockholders
are required in connection with the Proposed Merger,  in addition to a number of
other conditions, there can be no assurance that the Proposed Merger will occur.

Drilling Highlights

     During the first six months of 2004, the Company incurred $348.8 million in
finding  and  development   costs  including   $134.7  million  for  development
activities,  $156.1  million for  exploration  activities  and $58.0  million on
acquisitions.   The  majority  of  the  Company's  development  and  exploration
expenditures   were  spent  on  drilling  wells,   acquiring  seismic  data  and
constructing  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 six months ended June 30,
2004:

     Domestic.  The Company spent $224.4  million during the first six months of
2004 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  $134.3  million  (93  percent  of which was spent in the Gulf of
Mexico) of  drilling,  construction,  acquisition  and seismic  capital.  In the
deepwater Gulf of Mexico, the Company completed three development projects,  had
development  activities on one  significant  project  underway and drilled three
significant  exploration  wells during the first half of 2004. During the second
quarter,  the  Company  was also  awarded  leases  on 19 Gulf of  Mexico  blocks
covering approximately 102,000 acres, of which 14 are located in the deepwater.

o    Falcon Corridor - During the first quarter of 2003, the Company drilled its
     Harrier discovery, which was completed as a one-well subsea tie-back to the
     Falcon  field  facilities  and placed on  production  in January  2004.  In
     addition,  during  the third  quarter  of 2003,  the  Company  successfully
     drilled the  Tomahawk and  Raptor prospects,  which were  also developed as
     single-well  subsea  tie-backs to the Falcon field facilities and placed on
     production in June 2004. To accommodate  the  incremental  production  from
     Harrier,  Tomahawk  and Raptor as well as potential  throughput  associated
     with  additional  planned  exploration,  an  additional  parallel  pipeline
     connecting  the Falcon  field to the Falcon  Nest  platform  on the Gulf of
     Mexico shelf has been added, doubling its capacity. The Company holds a 100
     percent  working  interest  and  operates  all four  fields  in the  Falcon
     Corridor. In addition,  the Company may drill an additional Falcon Corridor
     exploration prospect during the second half of 2004.

o    Devils Tower Area - The Dominion-operated  Devils Tower development project
     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 spar has
     slots for eight dry tree wells and up to two subsea  tie-back risers and is
     capable of handling 60 MBbls of oil per day and 60 MMcf of gas per day. Two
     Devils  Tower  wells were  completed  and placed on  production  during the

     second quarter of 2004, while six additional wells will be completed during
     the remainder of 2004,  including two wells during the third  quarter,  and
     into early 2005. In addition, three subsea tie-back wells in the Goldfinger
     and Triton satellite  discoveries to the Devils Tower field are expected to
     be  jointly  tied  back to the  Devils  Tower  spar with  first  production
     expected  in 2005.  Production  is  expected  to  continue  to  increase as
     additional  wells are  individually  completed  from the spar.  The Company
     holds a 25 percent working interest in each of the above projects.

     In  addition  to the  development  and  exploration  projects  above in the
deepwater Gulf of Mexico,  the Company  participated in three sub-salt deepwater
prospects during the first half of 2004 of which one well was successful and two
were  noncommercial.  A sidetrack  well in the  Dominion-operated  Thunder  Hawk
discovery at Mississippi  Canyon Block 734  encountered in excess of 300 feet of
net oil pay in two high-quality  reservoir zones, and the partners are currently
evaluating appraisal and development options, with an additional well to further
delineate  the field  likely to commence in late 2004.  The Company  owns a 12.5
percent working interest in the discovery. The Company also anticipates that its
Ozona Deep discovery will be sanctioned during the latter part of 2004.

     The Company's joint exploration  agreement with Woodside Energy (USA), Inc.
("Woodside"),  a  subsidiary  of Woodside  Energy Ltd.  of  Australia,  has been
extended for an additional year through 2005 over the shallow-water  Texas shelf
region of the Gulf of Mexico.  Completion operations on the Midway prospect, the
fourth well drilled under this partnership, will begin late in the third quarter
of 2004 after  which the well will be tested and  evaluated  prior to being tied
back to an existing  production  platform.  If successful,  first  production is
anticipated  during the first  quarter  of 2005.  The  Company  has a 50 percent
working interest in this well. The four additional wells to be drilled under the
agreement  were mutually  agreed to be deferred until more technical work can be
performed on the  prospects  by both  companies.  Additionally,  the Company and
Woodside are evaluating  shallower gas prospects on the Gulf of Mexico shelf for
possible inclusion in the 2004 or 2005 drilling program.

     Alaska area.  The Company  spent $24.8 million of  acquisition  and seismic
capital to add to its leasehold position and expand its North Slope seismic data
coverage.  In June 2004, Pioneer announced that it agreed to a joint exploration
program in the National Petroleum  Reserve-Alaska ("NPR-A") located on the North
Slope with  ConocoPhillips  and Anadarko Petroleum  Corporation.  At the federal
lease  sale  held June 3,  2004 in  Anchorage,  Pioneer  was the  apparent  high
co-bidder  on 63  tracts  covering  approximately  717,000  acres  in the  NPR-A
Northwest  Planning  Area.  Pioneer  will  participate  with a 20  percent to 30
percent working interest in the acreage operated by ConocoPhillips. Pioneer also
acquired a 20 percent  interest  in 167,000  total acres in the  adjacent  NPR-A
Northeast  Planning Area and in federal offshore blocks,  including  seismic and
geologic data.

     During  2002,  the  Company  acquired a 70  percent  working  interest  and
operatorship in ten state leases on Alaska's North Slope.  Associated therewith,
the  Company  drilled  three  exploratory  wells  during 2003 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  on a  stand-alone  basis.
However, the wells also encountered thick sections of oil-bearing  Jurassic-aged
sands,  and the first well flowed at a rate of  approximately  1,300 barrels per
day. In January  2004,  the Company  farmed-into  a large  acreage  block to the
southwest of the Company's discovery.  During the remainder of 2004, the Company
plans to analyze seismic data and technical information from other wells drilled
southwest of its discovery and evaluate the feasibility of potential development
options.

     Permian Basin area.  The Company spent $42.2 million of capital  during the
first six months of 2004 primarily on development  drilling in the Spraberry oil
trend where the Company plans to drill approximately 100 wells during 2004. Also
included in the capital  spent during the first half of 2004 was a $20.2 million
acquisition  of various  working  interests in  approximately  600 Spraberry oil
wells, 400 of which were already operated by the Company.

     Mid-Continent  area.  The Company spent $23.1 million of capital during the
first six months of 2004  primarily in the West  Panhandle  field in Texas where
the Company plans to drill approximately 110 wells during 2004. The Company also
plans to  drill  approximately  20 wells  during  2004 in the  Hugoton  field in
Kansas.

     Argentina.  The Company  spent $54.0 million of  acquisition,  drilling and
seismic  capital  during  the  first  six  months  of 2004.  With  the  economic
environment  in Argentina  stabilizing  and the  potential for  improvements  in
future gas prices,  the Company  increased  its capital  budget in Argentina for
2004 to approximately $100 million.

     The  Company's  drilling  activities  in Argentina  continue to confirm the
presence of  significant  deep gas reserves.  During the second quarter of 2004,
the Company completed the expansion of its Loma Negra gas plant in Neuquen and a
20-mile pipeline to deliver gas from the Company's  development  projects in the
Portezuelos  and Anticlinal  Campamento  fields  located west of the plant.  The
Company  also  acquired  additional  3-D seismic in support of future  Argentine
drilling plans.

     Canada.  The  Company  spent $29.7  million of  acquisition,  drilling  and
seismic  capital  during the first  half of 2004,  primarily  in the  Chinchaga,
Martin  Creek and Lookout  Butte areas that are mainly  accessible  for drilling
during the winter months.

     Africa.  The  Company  spent $40.7  million of  acquisition,  drilling  and
seismic  capital  during the first six months of 2004 primarily in South Africa,
Tunisia, Gabon and Equatorial Guinea.

     South  Africa.  The Company  spent $6.2 million  primarily to drill a water
injection  well at the Sable  field in an  attempt to  enhance  production.  The
production  impact of the water injection well is not expected to be fully known
until later in 2004.  The Company also  continues  to evaluate the  potential to
develop its gas reserves by  attempting to establish a contract to supply gas to
an existing synthetic fuels plant.

     Tunisia.  The Company  spent $4.0  million of capital  during the first six
months  of  2004,  primarily  to place  its  most  recent  discovery,  Hawa,  on
production and to drill another  exploration  well on its Adam  concession,  the
Dalia discovery in which the Company has a 28 percent working interest, that was
placed on production subsequent to quarter-end.  The well is currently producing
at an initial rate of  approximately  1,600 barrels per day from one zone.  Upon
completion of the initial production phase, the well is expected to produce from
multiple zones at significantly  higher rates. During the remainder of 2004, the
Company  plans to drill an  exploration  well on the  Company-operated  El Hamra
permit and a development well at Hawa, which is located on the ENI-operated Adam
concession. In addition, the Company plans to drill another exploration well and
perform  additional  tests on the  discovery  on its  Anadarko-operated  Anaguid
permit during the second half of 2004.

     Gabon.  The  Company  spent $14.0  million of capital  during the first six
months of 2004 to drill five  exploration  wells, one of which was successful in
extending the planned  development  area to the south.  The remaining four wells
were  expensed  as dry  holes.  The  Company  is  currently  in the  process  of
completing the plan of  development to be filed with the government  late in the
third quarter of 2004. If approved,  development  operations  will commence with
first production expected in late 2006 or early 2007.

     Equatorial  Guinea.  The Company  spent $13.3  million of  acquisition  and
drilling  capital  during  the first six  months of 2004 to acquire a 40 percent
working interest in 400,000 acres of Block H offshore  Equatorial  Guinea,  West
Africa.  The  Bravo  1 well  was  drilled  in June  2004  and  determined  to be
noncommercial.  The Company has several  other  prospects on the blocks that are
being evaluated for future drilling.

Results of Operations

     Oil and gas revenues.  Revenues from oil and gas operations  totaled $447.0
million  and $893.5  million for the three and six months  ended June 30,  2004,
respectively,  compared  to  $344.2  million  and  $629.2  million  for the same
respective  periods of 2003.  The  increases in oil and gas revenues  during the
three and six months  ended June 30,  2004,  as compared to the same  respective
periods of 2003,  were primarily  attributable  to increases in sales volumes in
the United States, Argentina, South Africa and Tunisia and increases in realized
oil, NGL and gas prices.

     Per  BOE  average   daily   production,   on  a   second-quarter   2004  to
second-quarter 2003 comparison, increased by 18 percent worldwide, by 12 percent
in the United States,  by 15 percent in Argentina and the Company realized first
production  from Africa  during the second  half of 2003.  Second  quarter  2004
average daily  production in Canada decreased by nine percent as compared to the
second quarter of 2003 due to normal decline rates.

     During the first half of 2004 as  compared  to the first half of 2003,  per
BOE average daily production increased by 30 percent worldwide, by 23 percent in
the United States, by 22 percent in Argentina and, as previously mentioned,  the
Company  realized first  production  from Africa during the second half of 2003.
Average  daily  production  declined by five percent in Canada  during the first
half of 2004 as compared to the first half of 2003 due to normal decline rates.

     Oil and gas sales  from the  Company's  deepwater  Gulf of  Mexico  Harrier
field,  Devils Tower project and Raptor and Tomahawk  fields were first realized
during January,  May and mid-June 2004,  respectively,  and oil sales were first
realized from the Company's  Tunisian and South African oil projects  during the
second and third  quarters of 2003,  respectively.  Argentine  oil and gas sales
volumes were higher than anticipated during the first half of 2004 primarily due
to strong energy demand during their summer and fall seasons.

     Third  quarter 2004  production  is expected to average  185,000 to 200,000
BOEs per day, reflecting the incremental  production expected from Devils Tower,
Tomahawk and Raptor, the variability of oil cargo shipments in Tunisia and South
Africa,  and the  seasonal  increase  in gas demand  during  Argentina's  winter
season.

     As discussed above, oil and gas revenues for the three and six months ended
June 30, 2004 were positively  impacted by commodity price increases.  Comparing
the second  quarter of 2004 to the same period in 2003,  the  Company's  average
reported  worldwide oil price increased 15 percent,  average reported  worldwide
NGL prices  increased  28 percent  and  average  reported  worldwide  gas prices
increased five percent.  However, realized Argentine oil prices decreased during
the second quarter of 2004 primarily due to the  implementation of a new formula
for  domestic  oil prices to bring them in  approximate  parity with oil exports
that are subject to a 20 percent  export tax. In general,  the formula  provides
that if the average  NYMEX  price for crude oil  exceeds $36 per Bbl,  Argentine
producers will receive 80 percent of the price they would otherwise  receive for
domestic  sales,  less normal  quality  differentials,  and if the average NYMEX
price is below $36 per Bbl,  Argentine  producers will receive 86 percent of the
price they would  otherwise  receive for  domestic  sales,  less normal  quality
differentials.  The 14 percent increase in Argentine realized gas prices was the
result of a federal decree  governing  future gas price  increases to industrial
users and large  customers  during the next two years which became  effective in
May.  Comparing  the first six  months of 2004 to the same  period in 2003,  the
Company's  average  reported  worldwide oil price increased 12 percent,  average
reported  worldwide  NGL  prices  increased  13  percent  and  average  reported
worldwide gas prices increased six 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
swap and collar  contracts in order 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.  During the three and six months
ended June 30, 2004, the Company's  commodity price hedges decreased oil and gas
revenues by $56.1 million and $86.9 million,  respectively, as compared to $22.6
million and $73.0 million during the same respective periods in 2003. 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 six months ended June 30, 2004 and 2003.

     Oil and gas  production  costs.  During the three and six months ended June
30, 2004, total production costs per BOE averaged $5.60 and $5.44, respectively,
representing  an  increase  of  $.50  per  BOE  (ten  percent)  and  no  change,
respectively,  as compared to total  production costs per BOE of $5.10 and $5.44
during  the same  respective  periods  of 2003.  Lease  operating  expenses  and
workover  costs  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 total  production  costs per BOE during the three  months
ended June 30, 2004, as compared to the same period in 2003, is primarily due to
(i) two months of fixed  lease  operating  expenses  associated  with the phased
start-up  of the Devils  Tower  project in May which are  expected to decline as
additional  Devils Tower wells are  completed  during the  remainder of 2004 and
into 2005,  (ii) higher lease operating  expenses  associated with the Company's
South African oil production,  (iii) increased workover costs and (iv) increased
ad valorem taxes.

     During the six months  ended June 30,  2004,  as compared to the six months
ended June 30, 2003,  higher lease  operating  expenses  associated with Gulf of
Mexico and African  production  (which  required  minimal field fuel and are not
subject to ad valorem  taxes) and higher per BOE  workover  costs were offset by
decreases in per BOE field fuel and ad valorem tax expenses.

     The  following  tables  provide  the  components  of  the  Company's  total
production  costs per BOE and total  production costs per BOE by geographic area
for the three and six months ended June 30, 2004 and 2003:

     Based on  market-quoted  commodity  prices  during  July 2004,  the Company
expects third quarter 2004  production  costs to average $5.40 to $5.90 per BOE,
based on current gas price  outlooks  and Gulf of Mexico and African  production
forecasts.

     Depletion,  depreciation  and  amortization  expense.  The Company's  total
depletion, depreciation and amortization expense per BOE was $8.37 and $8.22 for
the three and six months ended June 30, 2004, respectively, as compared to $6.95
and $6.55 during the same respective periods of 2003. Depletion expense per BOE,
the largest component of depletion,  depreciation and amortization  expense, was
$8.21 and $8.06 per BOE  during the three and six  months  ended June 30,  2004,
respectively,  as compared to $6.78 and $6.37 per BOE during the same respective
periods of 2003. The increases in per BOE depletion expense during the three and
six months ended June 30, 2004,  as compared to the same  respective  periods of
2003,  are  primarily due to a greater  proportion  of the Company's  production
being derived from higher cost-basis  deepwater Gulf of Mexico and South African
developments.

     The following  table  provides the Company's  depletion  expense per BOE by
geographic area for the three and six months ended June 30, 2004 and 2003:

          Worldwide.........................   $  8.21   $  6.78   $  8.06   $  6.37


     The  Company  expects  third  quarter  2004  depletion,   depreciation  and
amortization  expense to average $8.75 to $9.25 per BOE, as a greater proportion
of the Company's  production is being produced from higher-cost  basis deepwater
Gulf of Mexico and South African properties.

     Exploration,  abandonments,  geological and geophysical costs. Exploration,
abandonments,  geological  and  geophysical  costs were $39.7 million and $120.2
million  during the three and six months ended June 30, 2004,  respectively,  as
compared to $47.0 million and $82.9 million during the same  respective  periods
in 2003. The decrease in exploration,  abandonments,  geological and geophysical
costs  during the second  quarter of 2004 as compared  to the second  quarter of
2003 is  primarily  comprised of a $9.5  million  decrease in dry hole  expense,
partially  offset by a $2.6  million  increase  in  geological  and  geophysical
expense.  Significant  components of the  Company's dry hole expense  during the
second quarter of 2004 included $9.5 million for the  abandonment of a well that
was  drilled  in  2002  along  the  southern  portion  of the  Olowi  block  oil
accumulation in Gabon which is not included in the current  development plan and
$6.1 million on the Bravo prospect offshore  Equatorial  Guinea. The increase in
exploration,  abandonments,  geological and  geophysical  costs during the first
half of 2004 as compared to the first half of 2003 is  primarily  comprised of a
$21.5  million  increase  in dry hole  expense and a $14.0  million  increase in
geological and geophysical expenses. Significant components of the Company's dry
hole  expense  during the first half of 2004  included  $26.7  million and $10.9
million  on the  Company's  deepwater  Gulf of  Mexico  Juno  and  Myrtle  Beach
prospects, respectively, $18.7 million on the Company's Gabonese Olowi prospect,
$6.1 million on the Company's Bravo prospect offshore Equatorial Guinea and $486
thousand of South African credit adjustments. During the first half of 2004, the
Company completed and evaluated 66 exploration/extension wells, 37 of which were
successfully  completed  as  discoveries.  During the same  period in 2003,  the
Company completed and evaluated 73 exploration/extension wells, 35 of which were
successfully completed as discoveries.

     The  Company   expects  third  quarter  2004   exploration,   abandonments,
geological  and  geophysical  costs to be $25 million to $45 million,  dependent
largely on exploratory drilling results and expected seismic expenditures.

     General and administrative expense.  General and administrative expense for
the  three and six  months  ended  June 30,  2004 was  $17.2  million  and $35.5
million, respectively, as compared to $13.6 million and $29.1 million during the
same  respective  periods in 2003.  The increases in general and  administrative
expense   are   primarily   due   to   increases   in   administrative    staff,
performance-related  compensation  costs and  increases in the  amortization  of
restricted  stock awards of $1.5  million and $2.2 million  during the three and
six months ended June 30, 2004, respectively, as compared to the same respective
periods of 2003.

     The Company expects third quarter 2004 general and  administrative  expense
to be $17 million to $19 million.

     Accretion of discount on asset retirement obligations. During the three and
six months  ended June 30,  2004,  accretion  of  discount  on asset  retirement
obligations was $2.0 million and $4.0 million, respectively, as compared to $1.2
million  and $2.3  million  during  the same  respective  periods  of 2003.  The
increases in accretion of discount on asset retirement obligations are primarily
due to the increase in future  plugging and abandonment  obligations  related to
the  deepwater  Gulf of Mexico,  Tunisian  and South  African  wells which began
production during the twelve months ended June 30, 2004. 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 asset retirement obligations.

     The Company  expects  third  quarter  2004  accretion  of discount on asset
retirement obligations to be approximately $2 million.

     Interest expense.  Interest expense was $21.4 million and $43.0 million for
the three and six months ended June 30, 2004, respectively, as compared to $23.8
million and $46.3 million for the same respective  periods in 2003. The decrease
in interest  expense during the second quarter of 2004 as compared to the second
quarter  of 2003 is  primarily  attributable  to  reduced  borrowings  under the
Company's  Revolving Credit Agreement and an $866 thousand  increase in interest
rate hedge  gains,  partially  offset by a $586  thousand  decrease  in interest
capitalized as the Company has completed major development  projects in the Gulf
of Mexico and South Africa.  The decrease in interest  expense  during the first
half of 2004 as compared to the first half of 2003 is primarily  attributable to
reduced  borrowings  under the Company's  Revolving  Credit Agreement and a $1.6
million  increase  in  interest  rate hedge  gains,  partially  offset by a $1.4
million decrease in interest capitalized.  The weighted average interest rate on
the Company's  indebtedness  for each of the three and six months ended June 30,
2004 was 5.2  percent,  as  compared to 5.4 percent and 5.2 percent for the same
respective periods in 2003, including the effects of the Company's interest rate
swaps.

     As is  further  described  in Note L of  Notes  to  Consolidated  Financial
Statements  included in "Item 1. Financial  Statements",  the Company  exchanged
$526.9  million of three  existing  series of senior notes for a like  principal
amount of New Notes and cash  during July 2004.  In  accordance  with GAAP,  the
Company will account for the debt exchange during the third quarter of 2004 as a
replacement  of  the  exchanged  debt  and  will  amortize  the  $109.0  million
associated  payment  of the  trading  premium or market  value of the  exchanged
senior  notes in  excess  of their  stated  value,  along  with the  unamortized
carrying values attributable to the issuance costs, discounts and deferred hedge
gains and losses of the exchanged debt, as adjustments of interest  expense over
the remaining terms of the New Notes.

     The Company  expects third quarter 2004 interest  expense to be $21 million
to $24 million.

     Other expenses.  Other expenses for the three and six months ended June 30,
2004 were $8.3  million  and $8.5  million,  respectively,  as  compared to $5.6
million and $10.8 million for the same respective  periods in 2003. The increase
in other  expenses  during the three months ended June 30, 2004,  as compared to
the same period of 2003, is attributable to a $4.8 million  increase in bad debt
expense,   $1.4  million  of   transaction   costs   incurred  to  complete  the
aforementioned   debt   exchange,   and  a  $1.3   million   increase  in  hedge
ineffectiveness charges,  partially offset by a $1.5 million decrease in foreign
currency  exchange losses,  a $1.2 million decrease in Argentine  personal asset
taxes and other aggregate expense  fluctuations.  The decrease in other expenses
during the six months  ended June 30,  2004,  as  compared to the same period of
2003, is attributable to a $1.8 million  decrease in foreign  currency  exchange
losses,  a $.9 million  decrease  in  Argentine  personal  asset taxes and other
aggregate expense fluctuations.

     Income tax provision.  During the three and six months ended June 30, 2004,
the Company recognized income tax provisions of $51.8 million and $91.5 million,
respectively,  as  compared  to $2.6  million  and  $4.9  million  for the  same
respective periods in 2003. The Company's  effective tax rate is higher than the
combined  United States federal and state statutory rate of  approximately  36.5
percent  primarily due to the reversal of the Company's  United States  deferred
tax  asset  valuation  allowances  during  the  third  quarter  of 2003  and the
aforementioned  international  exploration and abandonment expenses that created
deferred tax benefits which cannot be recognized until sufficient future taxable
income  in those  countries  is  assured.  See  Note C of Notes to  Consolidated
Financial  Statements included in "Item 1. Financial  Statements" for additional
information regarding the Company's income taxes.

     During  the third  quarter of 2004,  the  Company  estimates  that its cash
income taxes will be $4 million to $8 million  principally  related to Argentine
and  Tunisian  income  taxes and nominal  alternative  minimum tax in the United
States.  The  Company's  effective  income tax rate is expected to range from 36
percent to 39 percent based on current capital spending plans.

     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 deferred income taxes.

Capital Commitments, Capital Resources and Liquidity

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

     Oil and gas properties.  The Company's cash  expenditures  for additions to
oil and gas  properties  during  the three and six months  ended  June 30,  2004
totaled  $183.6  million  and  $350.8  million,  respectively,  as  compared  to
additions to oil and gas  properties of $134.3 million and $387.1 million during
the same  respective  periods of 2003.  During  the three and six month  periods
ended June 30, 2004,  the  Company's  additions to oil and gas  properties  were
funded by $264.7  million and $518.3  million of net cash  provided by operating
activities, respectively. The Company's second quarter 2003 additions to oil and
gas  properties  were funded by $189.9 million of net cash provided by operating
activities.  During the six months ended June 30, 2003, the Company's  additions
to oil and gas properties  were funded by $324.2 million of net cash provided by
operating  activities,  $25.7 million of proceeds from the disposition of assets
and borrowings under long-term debt.

     Contractual  obligations,  including  off-balance  sheet  obligations.  The
Company's  contractual  obligations  include  long-term debt,  operating leases,
drilling  commitments,   derivative  obligations  and  other  liabilities.  From
time-to-  time,  the Company  enters into  off-balance  sheet  arrangements  and
transactions that can give rise to material off-balance sheet obligations of the
Company.  As of June 30, 2004, the material  off-balance sheet  arrangements and
transactions  that the Company has entered into  include (i) undrawn  letters of
credit,  (ii) operating lease  agreements,  (iii) drilling  commitments and (iv)
contractual  obligations for which the ultimate settlement amounts are not fixed
and  determinable  such as  derivative  contracts  that are  sensitive to future
changes in commodity prices and gas transportation  commitments.  Other than the
Company's derivative obligations and the aforementioned exchange of senior notes
during  July  2004,  there  have been no  material  changes  in its  contractual
obligations  since December 31, 2003. See "Item 3.  Quantitative and Qualitative
Disclosures  About  Market Risk" for a table of changes in the fair value of the
Company's open derivative contract  liabilities during the six months ended June
30, 2004.

     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 2004.

     Operating activities.  Net cash provided by operating activities during the
three and six months ended June 30, 2004 was $264.7 million and $518.3  million,
respectively,  as  compared to $189.9  million  and $324.2  million for the same
respective  periods in 2003.  The  increases  in net cash  provided by operating
activities were primarily due to higher production  volumes and higher commodity
prices.

     Investing  activities.  Net cash used in  investing  activities  during the
three and six months ended June 30, 2004 was $192.2 million and $364.5  million,
respectively,  as  compared to $128.3  million  and $367.7  million for the same
respective  periods  of  2003.  The  increase  in net  cash  used  in  investing
activities  during the second quarter of 2004, as compared to the second quarter
of 2003, was primarily due to second quarter 2004 acquisitions of proved oil and
gas  properties  in the United  States  Spraberry  field and  unproved  property
interests  in Alaska and  Equatorial  Guinea.  The  decrease in net cash used in
investing  activities  during the first half of 2004,  as  compared to the first
half of 2003, was primarily due to a $36.3 million  decrease in additions to oil
and gas  properties,  partially  offset by a $25.2 million  decrease in proceeds
from disposition of assets.

     Financing  activities.  Net cash used in  financing  activities  during the
three and six months ended June 30, 2004 was $66.1  million and $157.5  million,
respectively.  In  comparison,  net cash used in financing  activities was $57.3
million  during the three  months  ended June 30, 2003 and net cash  provided by
financing  activities  was $45.7  million  during the six months  ended June 30,
2003.  During the three and six month periods  ended June 30, 2004,  the Company
has repaid $46.0 million and $136.0 million of long-term debt, respectively,  as
compared  to a repayment  of $57.2  million of  long-term  debt during the three
months ended June 30, 2003 and $44.5 million of net long-term  borrowings during
the six months ended June 30, 2003. The reductions in long-term debt were funded
during 2004 by increased net cash provided by operating  activities.  During the
three and six months ended June 30, 2004,  the Company also used $9.7 million to
purchase  320,000 shares of treasury stock and $15.3 million to purchase 503,300
shares of treasury stock, respectively.

                        PIONEER NATURAL RESOURCES COMPANY


     During March 2004,  the Company's  board of directors  also declared a $.10
per common share semiannual dividend,  payable on April 13, 2004 to shareholders
of record on March 29, 2004. Associated therewith, the Company distributed $12.0
million of aggregate  dividends  during April 2004.  If declared by the board of
directors,  the Company's second semiannual  dividend will be distributed during
October 2004.

     The Company's  operating,  investing and  financing  activities  during the
third  and  fourth  quarters  of  2004  will  be  materially   impacted  by  the
aforementioned  July 2004 debt  exchange  and by the Proposed  Merger.  The debt
exchange  extended the maturities on $526.9  million of the Company's  long-term
debt until 2016,  reduced the coupon  interest rate on the New Notes as compared
to the  exchanged  notes and used  $109.0  million  of cash for  exchange  price
payments, which represented the trading premium or market value of the exchanged
notes in excess of their stated value. The Proposed Merger, if consummated, will
be accounted for as a purchase  business  combination and will materially expand
the Company's assets,  liabilities,  shareholders'  equity,  outstanding  common
shares, forecasted production volumes and general scope of operations.

     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.

     Liquidity.  The Company's  principal source of short-term  liquidity is the
Revolving Credit  Agreement.  Outstanding  borrowings under the Revolving Credit
Agreement totaled $24.0 million as of June 30, 2004.  Including $49.3 million of
undrawn and outstanding  letters of credit under the Revolving Credit Agreement,
the Company has $626.7 million of unused borrowing capacity as of June 30, 2004.

     Book capitalization and current ratio. The Company's book capitalization at
June  30,  2004  was  $3.2  billion,  consisting  of debt of  $1.4  billion  and
stockholders' equity of $1.8 billion.  Consequently,  the Company's debt to book
capitalization  decreased  to 43.8 percent at June 30, 2004 from 46.9 percent at
December 31, 2003. The Company's ratio of current assets to current  liabilities
was .54 at June 30, 2004 and .48 at December 31, 2003.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

     The following  quantitative and qualitative  disclosures  about market risk
are  supplementary to the quantitative and qualitative  disclosures  provided in
the Company's  Annual Report on Form 10-K for the year ended  December 31, 2003.

     The following  disclosures  provide  specific  information  about  material
changes that have occurred since December 31, 2003 in the Company's portfolio of
financial  instruments.  The  Company  may  recognize  gains or losses in future
earnings  on these  instruments  from  changes in  commodity  prices or interest
rates.

     Interest  rate  sensitivity.  During March 2004,  the Company  entered into
interest rate swap  contracts on an aggregate  $150 million  notional  amount to
hedge  the fair  value of its  7-1/2  percent  senior  notes.  The  terms of the
interest rate swap contracts  match the scheduled  maturity of the hedged senior
notes,  require  the  counterparties  to pay the Company a 7-1/2  percent  fixed
annual interest rate and require the Company to pay the counterparties  variable
annual  interest  rates equal to the  periodic  six-month  LIBOR plus a weighted
average annual margin of 3.71 percent.

     During April 2004, the Company entered into interest rate swap contracts on
an aggregate $150 million  notional  amount to hedge the fair value of its 9-5/8
percent senior notes.  The terms of the interest rate swap  contracts  match the
scheduled maturity of the hedged senior notes, require the counterparties to pay
the Company a 9-5/8 percent  fixed annual  interest rate and require the Company
to pay the  counterparties  variable annual interest rates equal to the periodic
six- month LIBOR plus a weighted average annual margin of 5.66 percent.

     During June 2004,  the Company  entered into costless  collar  contracts to
hedge the  yield on the  benchmark  U.S.  Treasuries.  The  terms of the  collar
contracts  fixed  the  annual  yield on $250  million  notional  amount  of U.S.
Treasuries  within a yield  collar  having a ceiling  rate of 4.70 percent and a
floor rate of 4.65 percent.  The yield on the U.S. Treasuries as of July 7, 2004
was the benchmark rate used to determine the coupon rate on the Company's  5-7/8
percent  senior notes due July 15,  2016,  which were issued on July 15, 2004 in
exchange for portions of three series of the Company's outstanding senior notes.
See Note L of Notes to Consolidated  Financial  Statements  included in "Item 1.
Financial  Statements" and Capital Commitments,  Capital Resources and Liquidity
included in Item 2. "Management's Discussion and Analysis of Financial Condition
and Results of  Operations"  for additional  information  regarding the July 15,
2004 debt exchange.

     The following  table provides  information  about the debt  obligations and
derivative financial instruments of the Company that are sensitive to changes in
interest  rates as of June 30, 2004.  For debt  obligations,  the table presents
maturities by expected  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 June 30, 2004. 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.  For interest rate swap contracts,  the table presents the
notional  amounts together with the fixed rate to be received by the Company and
the variable rate to be paid estimated based on the current  variable rate being
paid by the Company projected  forward  proportionate to the forward yield curve
for the six-month LIBOR.

     During July 2004 the Company entered into the following  transactions  that
materially  changed the Company's  portfolio of financial  instruments  that are
sensitive to changes in interest rates:

       o  The Company  terminated interest  rate swap  contracts on $140 million
          notional  amount  of its  7-1/2 percent  senior  notes.  In connection
          therewith,  the Company  paid $7.8  million to settle  $8.8 million of
          settlement losses for future periods offset by $1.0 million of accrued
          settlement  gains  through  the  date  of  termination.   The  Company
          continues to be a party to interest rate swaps on $10 million notional
          amount  whereby  the  Company  is paid a  fixed  annual rate  of 7-1/2
          percent and pays  the  counterparties a variable annual  rate equal to
          the periodic  six-month  LIBOR rate  plus a  weighted  average  annual
          margin of 3.72 percent.
       o  The Company  terminated interest  rate swap  contracts on  $90 million
          notional amount of  its 9-5/8  percent  senior  notes.  In  connection
          therewith,  the Company  paid $1.3  million to settle $1.8 million  of
          settlement losses for future periods offset by $.5  million of accrued
          settlement  gains  through  the  date  of  termination.   The  Company
          continues to be a party to interest rate swaps on $60 million notional
          amount  whereby  the  Company is  paid a  fixed annual  rate of  9-5/8
          percent and  pays the  counterparties a  variable annual rate equal to
          the  periodic  six-month  LIBOR  rate  plus a  weighted average annual
          margin of 5.62 percent.
       o  On July 15, 2004, the Company completed the aforementioned exchange of

the Company's  disclosure  controls and  procedures  (as defined in Exchange Act

reported within the time periods specified in the SEC's rules and forms.

changes in the Company's  internal control over financial  reporting (as defined
in Rule  13a-15(f)  under the Exchange Act) that  occurred  during the Company's
last fiscal quarter that have  materially  affected or are reasonably  likely to
materially affect the Company's internal control over financial reporting.
