          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.

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, 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 March 31, 2004 and for the three-month
periods  ended March 31, 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
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 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 for the three months ended
March 31,  2003.  See Notes C and E for  additional  information  regarding  the
Company's income taxes and asset retirement obligations, respectively.

     Inventories.  Inventories  are comprised of $15.6 million and $15.3 million
of lease and well  equipment and $1.6 million and $2.2 million of commodities as
of March 31, 2004 and December 31, 2003, respectively.  Lease and well equipment
is net of lower of cost or market allowances of $.6 million as of March 31, 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.   Stock-based  compensation  expense
associated  with option  grants was not  recognized  in the Company's net income
during the  three-month  periods  ended March 31, 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.  The
following table  illustrates the pro forma effect on net income and earnings per
share as if the Company had applied  the fair value  recognition  provisions  of
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" to stock-based  compensation  during the three-month periods ended
March 31, 2004 and 2003:

NOTE C.     Income Tax Assets

     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 March 31, 2004, the Company's valuation  allowances related to foreign tax
jurisdictions are $102.1 million.

NOTE D.     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
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
March 31, 2004,  the  carrying  value of the  Company's  fair value hedges was a
liability of $1.5 million.

     As of March 31, 2004, the carrying value of the Company's long-term debt in
the  accompanying   Consolidated   Balance  Sheets  included  $20.1  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
amortization  of net  deferred  hedge gains on  terminated  interest  rate swaps
reduced the Company's reported interest expense by $7.3 million and $5.9 million
during the  three-month  periods  ended March 31,  2004 and 2003,  respectively.
Settlements of open fair value hedges reduced the Company's  interest expense by
$167 thousand and $867 thousand during the  three-month  periods ended March 31,
2004 and 2003, respectively.

     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  derivatives'  gains or losses from the  measurement  of hedge
effectiveness.

     Cash flow hedges.  The Company utilizes commodity swap and collar contracts
to (i) reduce the effect of price  volatility  on the  commodities  the  Company
produces and sells,  (ii) support the  Company's  annual  capital  budgeting and
expenditure  plans and (iii) reduce commodity price risk associated with certain
capital  projects.  The Company also utilizes  interest  rate swap  contracts to
reduce the effect of interest rate  volatility  on the  Company's  variable rate
line of credit  indebtedness  and, from time to time,  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 March 31, 2004:

were no outstanding NGL hedge contracts at March 31, 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

     Hedge  ineffectiveness.  During the thee-month periods ended March 31, 2004
and 2003, the Company recognized other expense of $44 thousand and $1.8 million,
respectively,  related  to the  ineffective  portions  of its cash flow  hedging
instruments.

     Accumulated other comprehensive income (loss) ("AOCI") - net deferred hedge
losses,  net of tax.  As of March 31, 2004 and  December  31,  2003,  AOCI - net
deferred  hedge losses,  net of tax  represented  net deferred  losses of $158.9
million and $104.1 million,  respectively. The AOCI - net deferred hedge losses,
net of tax balance as of March 31, 2004 was  comprised of $276.3  million of net
deferred  hedge losses on the  effective  portions of open  commodity  cash flow
hedges,  $34.1 million of net deferred gains on terminated  cash flow hedges and
$83.2  million of associated  net deferred tax benefits.  The increase in AOCI -
net deferred  hedge  losses,  net of tax during the three months ended March 31,
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 hedge losses  associated with open cash
flow hedges remain subject to market price  fluctuations until the positions are
either  settled under the terms of the hedge  contracts or  terminated  prior to
settlement.  The net  deferred  hedge gains on  terminated  cash flow hedges are
fixed.

     During the twelve months ending March 31, 2005, based on current  estimates
of future commodity prices,  the Company expects to reclassify $188.5 million of
net deferred  losses  associated with open cash flow hedges and $33.2 million of
net deferred gains on terminated cash flow hedges from AOCI - net deferred hedge
losses,  net of tax to oil  and  gas  revenues.  The  Company  also  expects  to
reclassify  approximately  $56.7  million of net  deferred  income tax  benefits
during the twelve  months  ending March 31, 2005 from AOCI - net deferred  hedge
losses, net of tax to income tax provision.

     The  following  table  sets  forth,  as of March 31,  2004,  the  scheduled
reclassifications  of net deferred  hedge gains on  terminated  cash flow hedges
that will be recognized in the Company's future oil and gas revenues:

NOTE G.     Commitments and Contingencies

     Legal actions.  The Company is party to various legal actions incidental to
its business,  including,  but not limited to, the proceedings  described below.
The majority of these lawsuits primarily involve claims for damages arising from
oil and gas leases and ownership  interest  disputes.  The Company believes that
the ultimate disposition of these legal actions will not have a material adverse
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 and it now contains two
material claims.  First, the plaintiffs assert that they were improperly charged

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 $65  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  March 31, 2004,  the Company has settled  $21.6 million of the original
claim  amounts.  As of March 31, 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 March 31,
2004.

     On December 1, 2003, an  administrative  law judge issued a Partial Initial
Decision  denying the Company's  request to allow any waiver or set-off from the
refunds and  stating  that the Company  must pay the FERC  interest  rate on the
refund claims instead of the escrow  interest rate. As of December 31, 2003, the
Company had accrued an additional  $1.5 million  obligation  for the  difference
between the escrow  interest rate and the FERC interest  rate.  During the first
quarter of 2004, the FERC overruled this  administrative law judge's decision as
it relates to the payment of interest and stated that the escrow  interest  rate
is sufficient.  As of March 31, 2004, the Company  reversed the additional  $1.5
million  obligation that had been recorded for the difference between the escrow
interest  rate and the FERC  interest  rate.  The Company  intends to vigorously
appeal the  administrative  law judge's  decision denying waiver or set-off from
the refunds and believes  that the accrued  obligations  will be  sufficient  to
resolve the remaining claims.

NOTE H.     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-month  periods ended March 31, 2004 and
2003:

     the average market price of the common shares and would be anti-dilutive to
     the computations.

NOTE I.     Geographic Operating Segment Information

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

     The following  tables provide the Company's  interim  geographic  operating
segment  data for the  three-month  periods  ended  March  31,  2004  and  2003.
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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 2004
                                   (Unaudited)


NOTE K.     Subsequent Events

     Permian  Basin  acquisition.  On April 1, 2004,  the Company  completed the
acquisition of various working  interests in  approximately  600 Spraberry field
oil wells, 400 of which were already operated by the Company. The total purchase
price  of  this  acquisition  was  $19.7  million,   including  normal  purchase
adjustments.

     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"),  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.  The  Merger  Agreement
provides for a merger by which  Evergreen  will become a  subsidiary  of Pioneer
(the "Proposed Merger").

     In accordance  with the Merger  Agreement,  holders of 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 as set forth in the
first sentence of this paragraph.

     In  addition,  Evergreen  will seek to sell its  Kansas  assets  before the
closing  date of the Proposed  Merger.  Evergreen  stockholders  will receive an
additional cash payment of the greater of (i) $.35 per share  (approximately $15
million) as consideration from Pioneer for the Kansas properties in the Proposed
Merger,  or (ii) the gross proceeds less transaction  costs from the sale of the
Kansas  properties  to a third party that closes  before the closing date of the
Proposed Merger.

     The Company  intends to file with the SEC a Registration  Statement on Form
S-4 relating to the shares of Pioneer  common stock to be issued in the Proposed
Merger.  A  portion  of such  registration  statement  will  constitute  a 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 proxy  statement/prospectus  will be mailed to all stockholders during
the third quarter of 2004,  and that such meeting will be held, and the Proposed
Merger will be  consummated,  during the second half of 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.

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 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  2003 Annual Report on Form
10-K that is available from the SEC.

Financial and Operating Performance

     The Company's financial and operating  performance for the first quarter of
     2004 included the following highlights:
       o    A 57% increase in oil and gas revenue over that of the first quarter
            of 2003,  resulting from  increases in  commodity prices and volumes
            sold, as further described below.
       o    Growth  in the  Company's deepwater  Gulf of  Mexico  sales volumes,
            including initial production  from the Harrier  field during January
            2004.
       o    Higher  than  anticipated  Argentine  oil  and  gas  sales  volumes,
            primarily due to strong gas demand throughout their summer season.
       o    Higher  than  anticipated  South  African   oil  sales  due  to  one
            additional cargo shipment during the quarter.
       o    An 85 percent increase in net cash provided by operating activities,
            as compared to the  first quarter of 2003,  primarily resulting from
            increased oil and gas sales.
       o    A $.10 per common share semiannual dividend declared by the board of
            directors,  payable on April 13,  2004 to  shareholders of record on
            March 29, 2004.
       o    Rating agencies upgrade of the Company to investment grade status in
            response to  improved financial  position and earnings trends, along
            with other factors specific to the Company.

     The Company  recorded net income of $60.2 million ($.50 per diluted  share)
for the three months  ended March 31,  2004,  as compared to net income of $84.2
million ($.71 per diluted share) for the same period in 2003,  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. 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 SFAS 143. Income before income taxes and cumulative effect
of change in accounting  principle  increased by $28.9  million,  or 41 percent,
during the first  quarter of 2004 as  compared  to that of the first  quarter of
2003.  However,  as a result of the increase in earnings and 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 $37.5 million
in the first-quarter-2004 to first-quarter-2003 comparison.

     The Company's net cash provided by operating  activities was $253.6 million
for the three months ended March 31,  2004,  representing  an increase of $116.8
million,  as compared to net cash  provided by  operating  activities  of $136.8
million for the same  period in 2003.  During the three  months  ended March 31,
2004,  the Company used its net cash  provided by operating  activities  to fund
$167.2  million of  additions to oil and gas  properties  and,  together  with a
decease in cash on hand,  to repay $90.0 million of long-term  borrowings  under
the Company's $700 million  revolving  credit  agreement (the "Revolving  Credit
Agreement").

Proposed Merger with Evergreen Resources, Inc.

     As  described  in Note K of  Notes  to  Consolidated  Financial  Statements
included in "Item 1. Financial Statements",  on May 3, 2004, the Company entered
into the Merger Agreement with Evergreen,  a publicly traded independent oil and
gas  company  primarily  engaged  in  the  operation,  development,  production,
exploration and  acquisition  of  North  American  unconventional  natural  gas.


                                       26





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.
The Merger  Agreement  provides  for a merger by which  Evergreen  will become a
subsidiary of Pioneer.

     Proposed purchase terms. In accordance with the Merger  Agreement,  holders
of 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 as set forth in the
first sentence of this paragraph.

     In  addition,  Evergreen  will seek to sell its  Kansas  assets  before the
closing  date of the Proposed  Merger.  Evergreen  stockholders  will receive an
additional cash payment of the greater of (i) $.35 per share  (approximately $15
million) as consideration from Pioneer for the Kansas properties in the Proposed
Merger,  or (ii) the gross proceeds less transaction  costs from the sale 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
investments   in   high-impact,    high-return   exploration   and   acquisition
opportunities,  such  as the  Company's  investments  in the  deepwater  Gulf of
Mexico,  Alaska, South Africa,  Tunisia and Gabon. The Proposed Merger offers an
opportunity for the Company to rebalance its portfolio of long-lived  foundation
assets  with the  addition  of  Evergreen's  onshore  producing  asset  base and
low-risk development drilling program.  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  $30 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 "364-day  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  6-month  LIBOR rate plus a 100
basis point LIBOR margin.  The Company also intends to exercise its option under
the Revolving Credit Agreement allowing an increase in the facility's  borrowing
commitment to $1 billion.  During the one-year period  subsequent to the closing
of the  Proposed  Merger,  the  Company  may repay  the  364-day  Facility  with
available operating cash flows, available commitments under the Revolving Credit
Agreement or any combination of those or other available capital sources.

     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's  ratio of debt to book  capitalization  is expected to  approximate 47
percent immediately after the Proposed Merger closes in the latter part of 2004.



                                       27




     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 Company intends
to  implement  an  aggressive   commodity   hedging  program  of  Pioneer's  and
Evergreen's  2004 and 2005 forecasted oil and gas production.  The Company began
implementing  this program  prior to the  announcement  of the Proposed  Merger,
utilizing  commodity swap  contracts  entered into with  highly-rated  financial
institution  counterparties.  Consistent with this program, Evergreen has hedged
approximately  75 percent of its 2004 and 2005  forecasted gas  production.  The
Company  has hedged  approximately  35 percent  and 45 percent of its  remaining
forecasted   2004  worldwide   liquids  and  North   American  gas   production,
respectively,  and 30 percent of its forecasted 2005 worldwide liquids and North
American  gas  production.  See  Note  D  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 intends to file with the
SEC a  Registration  Statement  on Form S-4  relating  to the  shares of Pioneer
common stock to be issued in the Proposed Merger. A portion of such registration
statement will  constitute a 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 proxy statement/prospectus will be
mailed to all  stockholders  during  the third  quarter  of 2004,  and that such
meeting will be held, and the Proposed  Merger will be  consummated,  during the
second  half  of  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 quarter of 2004,  the Company  incurred  $164.1 million of
finding  and  development   costs  including   $102.0  million  for  exploration
activities,  $55.7  million  for  development  activities  and $6.4  million for
acquisitions.   The  majority  of  the  Company's  exploration  and  development
expenditures   was  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 three months ended March
31, 2004:

     Domestic.  The Company spent $99.3 million during the first quarter 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 $69.7 million of acquisition, drilling and seismic capital. In the
deepwater Gulf of Mexico,  the Company  completed one development  project,  had
development  activities  on two  significant  projects  underway  and had  three
significant exploration wells being drilled during the first quarter of 2004.

o    Falcon Area - 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 are being  developed as
     single-well subsea tie-backs to the Falcon field facilities. 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
     platform on the Gulf of Mexico shelf has been added,  doubling its capacity
     to 400  MMcf of gas per  day.  The  Tomahawk  and  Raptor  discoveries  are
     expected to start  production  during the latter half of the second quarter
     of 2004.  In  addition,  the  Company may drill an  additional  Falcon area
     exploration prospect during the fourth quarter 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.
     Eight Devils Tower wells and three subsea  tie-back wells in the Triton and
     Goldfinger fields have been drilled and are awaiting completion. Subsequent
     to quarter-end,  completion  operations on the first Devils Tower well were
     commenced and production  began in early May.  Production  will increase as
     the 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  projects  above in the  deepwater  Gulf of
Mexico, the Company  participated in three sub-salt  deepwater  prospects during
the first quarter of 2004 exposing the Company to significant reserve potential,
two of  which  were  noncommercial.  The  operator  of  the  third  prospect  is
conducting  open-hole  evaluations  to assess the rock and fluid  properties and
structural position of the well. Project sanctioning of the Company's Ozona Deep
discovery is expected to be completed 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.  The Midway  prospect,  the fourth  well  drilling
under this partnership, encountered 30 feet of net gas pay and is expected to be
tied back to an existing production  platform with first production  anticipated
during the second half of 2004. Three other intervals with an additional 60 feet
of gas bearing sands were also encountered and will require additional  analysis
to determine future commercial potential. The Company has a 37.5 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 drilling program.

     Alaska  area.  The Company  spent $8.3 million of  acquisition  and seismic
capital to add to its  leasehold  position and to acquire  seismic data over the
newly acquired acreage.  During the fourth quarter of 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.



                                       29





     Permian Basin area.  The Company spent $11.0 million of capital  during the
first  quarter of 2004  primarily on  development  drilling in the Spraberry oil
trend where the Company  plans to drill  approximately  100 wells  during  2004.
Included  in the  capital  spent  during  the first  quarter  of 2004 was a $1.0
million  deposit  related to the  acquisition  of various  working  interests in
approximately 600 Spraberry oil wells, 400 of which were already operated by the
Company.  On April 1, 2004,  the Company  consummated  this  transaction  for an
additional $18.7 million paid at closing.

     Mid-Continent  area.  The Company spent $10.3 million of capital during the
first quarter 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 this year in the Hugoton field in Kansas.

     Argentina.  The Company  spent $22.8 million of  acquisition,  drilling and
seismic capital during the first quarter of 2004. With the economic  environment
in  Argentina  stabilizing  and the  potential  for  improvements  in future gas
prices, the Company has doubled its capital budget in Argentina for 2004.

     The  Company's  drilling  activities  in Argentina  continue to confirm the
presence of  significant  deep gas reserves.  First  quarter 2004  Argentine gas
production  was the  highest  summer  production  in the  segment's  history and
Pioneer  expects  to  complete  the  expansion  of its Loma  Negra  gas plant in
Argentina over the next few months,  increasing  plant capacity by 25 percent as
demand  peaks  during  the  winter  months in  Argentina.  The  Company  is also
acquiring additional 3-D seismic in support of future Argentine drilling plans.

     Canada.  The  Company  spent $27.4  million of  acquisition,  drilling  and
seismic  capital  during the first quarter 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 $14.6  million of  acquisition,  drilling  and
seismic  capital  during the first quarter of 2004 in South Africa,  Tunisia and
Gabon.

     South Africa.  Near the end of the first quarter of 2004, the Company began
drilling  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 known  until later in 2004.  The  Company  also  continues  to  evaluate  the
potential  to develop  its large  quantity  of gas  reserves  by  attempting  to
establish a contract to supply gas to an existing synthetic fuels plant.

     Tunisia. The Company spent $1.5 million of capital during the first quarter
of 2004,  primarily to place its most recent  discovery,  Hawa,  on  production.
During  2004,  the Company  plans to drill one to two  exploration  wells on the
Company-operated  El  Hamra  permit,  a  development  well at Hawa  and  another
exploration well on the ENI-operated Adam concession.

     Gabon.  The Company spent $12.7 million of capital during the first quarter
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,
although  unsuccessful  and expensed as dry holes,  were helpful in defining the
future  development  of the oil rim.  The Company is currently in the process of
completing the plan of  development to be filed with the government  late in the
second quarter of 2004. If approved,  development  operations will commence with
first production expected in 2006.

Results of Operations

     Oil and gas revenues.  Revenues from oil and gas operations  totaled $446.5
million for the three months ended March 31,  2004,  compared to $285.0  million
for the same period in 2003.  The  increase in oil and gas  revenues  during the
first  quarter of 2004 as compared to the first  quarter of 2003 is  principally
attributable to (i) increased gas production  from the Company's  deepwater Gulf
of Mexico  projects,  including a full quarter of production  from the Company's
Falcon  field  that  first  produced  during  March  2003,   incremental  Falcon
production  attributable  to the March 28,  2003  purchase of the  remaining  25
percent  interest in the field and initial  production  in January 2004 from the
Harrier  field in the deepwater  Gulf of Mexico;  (ii) oil  production  from the
Company's  Tunisian  and South  African  projects  which first  began  producing
operations  during the second and third  quarters of 2003,  respectively;  (iii)
increased  oil, NGL and gas  production  from the  Company's  Argentine  assets,
primarily due to  strengthening  demand  fundamentals  in the country;  and (iv)
increases  in the  Company's  reported  oil,  NGL and gas prices  including  the
results of hedging activities.

     On a BOE basis,  worldwide average daily production increased by 45 percent
during the three months ended March 31, 2004,  as compared to the same period in
2003.  During the first  quarter of 2004,  as compared  to the first  quarter of
2003, worldwide oil production increased 50 percent; NGL production increased by
six percent;  and gas production  increased by 54 percent. Per BOE average daily
production,  on a first-quarter  to  first-quarter  comparison,  increased by 37
percent and 32 percent in the United States and Argentina,  respectively,  while
production  in Canada  decreased by a  negligible  amount.  Production  from the
Company's  Tunisian and South  African oil projects  began during the second and
third quarters of 2003, respectively.

     As discussed  above,  oil and gas revenues for the three months ended March
31, 2004 were positively  impacted by commodity price  increases.  Comparing the
first  quarter  of 2004 to the  same  period  in  2003,  the  Company's  average
worldwide oil price increased ten percent, average worldwide NGL price increased
one percent and average worldwide gas price increased six percent.



                                       31





     Second  quarter 2004  production is expected to average  180,000 to 195,000
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.

     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 first quarter of 2004,
the  Company's  commodity  price hedges  decreased oil and gas revenues by $30.7
million as compared to $50.4  million of commodity  hedge losses during the same
period  in  2003.  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,
2004 and 2003.

     Subsequent to March 31, 2004,  the Company  entered into new swap contracts
to hedge (i) 6,189 Bbls per day of the nine months  ended  December 31, 2004 oil
sales at a weighted average fixed price per Bbl of $36.74,  (ii) 10,000 Bbls per
day of 2005 oil sales at a weighted average fixed price per Bbl of $33.14, (iii)
30,000 Mcf per day of July through December 2004 gas sales at a weighted average
fixed price per MMBtu of $6.42 and (iv) 114,904 Mcf per day of 2005 gas sales at
a weighted  average fixed price per MMBtu of $5.54.  See  "Proposed  Merger with
Evergreen  Resources,  Inc. - Liquidity and capital structure",  for information
regarding the Company's hedge program.

     Oil and gas production costs. During the three months ended March 31, 2004,
total production  costs per BOE averaged $5.27,  representing a decrease of $.60
per BOE, or ten percent,  as compared to total production costs per BOE of $5.87
during the first quarter of 2003. Lease operating expenses and workover expenses
represent  the  components  of  production  costs  for  which  the  Company  has
management  control,  while  production  and ad  valorem  taxes and  field  fuel
expenses are directly related to commodity price changes.

     The decrease in total  production costs per BOE during the first quarter of
2004,  as compared  to the first  quarter of 2003,  is  primarily  comprised  of
decreases in production taxes and field fuel costs resulting from a $.42 per Mcf
decrease in realized gas prices excluding hedge results.

     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-month periods ended March 31, 2004 and 2003:

       Based on market-quoted  commodity prices  during April 2004,  the Company
expects second quarter 2004 production costs to average $5.20 to $5.70 per BOE.


                                       32






     Depletion,  depreciation  and  amortization  expense.  The Company's  total
depletion, depreciation and amortization expense per BOE was $8.07 and $6.06 for
the three-month periods ended March 31, 2004 and 2003,  respectively.  Depletion
expense  per  BOE,  the  largest   component  of  depletion,   depreciation  and
amortization, increased to $7.91 per BOE during the three months ended March 31,
2004, as compared to $5.86 per BOE during the same period in 2003, primarily due
to increases in higher cost-basis  deepwater Gulf of Mexico,  Tunisian and South
African production volumes.

     The following  table  provides the Company's  depletion  expense per BOE by
geographic area for the three-month periods ended March 31, 2004 and 2003:

     The  Company  expects  second  quarter  2004  depletion,  depreciation  and
amortization expense to average $8.00 to $8.50 per BOE.

     Exploration,  abandonments,  geological and geophysical costs. Exploration,
abandonments,  geological  and  geophysical  costs were $80.5 million during the
three months ended March 31, 2004, as compared to $35.9 million  during the same
period in 2003.  The  increase  in  exploration,  abandonments,  geological  and
geophysical  expense  during the first  quarter of 2004 as  compared to the same
period of 2003 is comprised of a $31.0 million increase in dry hole expense,  an
$11.4 million increase in geological and geophysical expenses and a $2.2 million
increase in leasehold  abandonments and other exploration expenses.  Significant
components of the  Company's  dry hole expense  during the first quarter of 2004
included  $26.4  million and $10.7 million on the  Company's  deepwater  Gulf of
Mexico Juno and Myrtle Beach prospects,  respectively, and $6.4 million and $2.8
million on the Company's Olowi and Dentale  prospects,  respectively,  in Gabon.
During  the first  quarter of 2004,  the  Company  completed  and  evaluated  52
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

     The  Company  expects  second  quarter  2004   exploration,   abandonments,
geological  and  geophysical  costs to be $25 million to $50 million,  dependent
largely on exploratory drilling results and expected seismic expenditures.



                                       33





     General and administrative expense.  General and administrative expense for
the  three-month  periods  ended March 31,  2004 and 2003 was $18.3  million and
$15.5 million,  respectively. The increase in general and administrative expense
is primarily due to increases in  administrative  staff and  performance-related
compensation costs.

     The Company expects second quarter 2004 general and administrative  expense
to be $16 million to $18 million.

     Accretion  of  discount  on  asset  retirement   obligations.   During  the
three-month  periods  ended  March 31, 2004 and 2003,  accretion  of discount on
asset  retirement  obligations was $2.0 million and $1.1 million,  respectively.
The  increase  in  accretion  of  discount on asset  retirement  obligations  is
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 March 31, 2004. See "Cumulative
effect  of  change  in  accounting  principle"  and  Notes B and E of  Notes  to
Consolidated Financial Statements included in "Item 1. Financial Statements" for
additional information regarding the Company's adoption of SFAS 143.

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

     Interest  expense.  Interest expense was $21.6 million for the three months
ended March 31, 2004,  as compared to $22.5 million for the same period in 2003.
The decrease in interest  expense is primarily due to a $1.0 million decrease in
interest incurred on the Revolving Credit Agreement,  primarily  associated with
reduced  borrowings  and a $.7 million  increase in interest  rate hedge  gains,
partially offset by a $.9 million decrease in interest capitalized. The weighted
average  interest rate on the Company's  indebtedness for the three months ended
March 31, 2004 was 5.31  percent as compared to 5.56 percent for the same period
in 2003, including the effects of the Company's interest rate swaps.

     The Company expects second quarter 2004 interest  expense to be $20 million
to $23 million.

     Other expenses.  Other expenses for the three-month periods ended March 31,
2004 and 2003 were $.2 million and $5.2 million,  respectively.  The decrease in
other  expenses is primarily  attributable  to a $1.8 million  decrease in hedge
ineffectiveness charges and a $.3 million decrease in foreign exchange losses.

     Income tax  provision.  During the three months  ended March 31, 2004,  the
Company  recognized an income tax provision of $39.8  million,  as compared to a
$2.3  million  tax  provision  recognized  during the same  period in 2003.  The
increase in the Company's  effective tax rate is primarily  attributable  to the
reversal of the Company's United States deferred tax asset valuation  allowances
during the third quarter of 2003. 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 second  quarter of 2004,  the  Company  estimates  that its cash
income taxes will be $3 million to $6 million.

     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 tax. 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 SFAS
143.

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-month  periods ended March 31, 2004 and
2003 totaled  $167.2  million and $252.8  million,  respectively.  The Company's
first quarter 2004 additions to oil and gas  properties  were funded by net cash
provided by operating  activities of $253.6 million. 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.


                                       34






     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 March 31, 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,  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  assets and  liabilities  during the three
months ended March 31, 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-month periods ended March 31, 2004 and 2003 were $253.6 million and $136.8
million, respectively. The increase in net cash provided by operating activities
was primarily due to higher production volumes and higher commodity prices.

     Investing  activities.  Net cash used in  investing  activities  during the
three-month periods ended March 31, 2004 and 2003 were $172.3 million and $239.5
million, respectively. The decrease in net cash used in investing activities was
primarily  due  to an  $85.5  million  decrease  in  additions  to oil  and  gas
properties.   The  decrease  is  primarily  attributable  to  a  $119.4  million
acquisition  of an additional 25 percent  interest in the Falcon field offset by
$15.3 million of proceeds from disposition of assets during the first quarter of
2003.

     Financing  activities.  Net cash used in  financing  activities  during the
three  months  ended  March 31,  2004 was $91.4  million as compared to net cash
provided by financing  activities  of $100.6  million  during the same period of
2003. The reduction in long-term debt was made possible by the combined  effects
of increased net cash provided by operating  activities and decreased  additions
to oil and gas  properties.  During the three months  ended March 31, 2004,  the
Company also used $5.6 million to purchase 183,300 shares of treasury stock.

     During March 2004,  the  Company's  board of directors  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
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.

     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 $70.0 million as of March 31, 2004. Including $28.2 million of
undrawn and outstanding  letters of credit under the Revolving Credit Agreement,
the  Company  has $601.8  million of unused  borrowing  capacity as of March 31,
2004.


                                       35






     Book capitalization and current ratio. The Company's book capitalization at
March  31,  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 45.3 percent at March 31, 2004 from 46.9 percent at
December 31, 2003. The Company's ratio of current assets to current  liabilities
was .48 at March 31, 2004 and December 31, 2003.

Status of Accounting Development

     In its review of registrants'  filings,  the staff of the SEC has taken the
position that  Statement of Financial  Accounting  Standards No. 141,  "Business
Combinations"  ("SFAS 141") and Statement of Financial  Accounting Standards No.
142,  "Goodwill and Other Intangible  Assets" ("SFAS 142"),  require oil and gas
companies to separately  report on their  balance  sheets the costs of leasehold
mineral rights,  including related accumulated  depletion,  as intangible assets
and provide related disclosures.

     The Company has historically  included  producing  leasehold mineral rights
costs in the proved properties caption on its Consolidated  Balance Sheets. This
classification  is  consistent  with  the  provisions  of SFAS  19 and  standard
industry  practice.   Almost  all  costs  included  in  the  Company's  unproved
properties  caption on the  Consolidated  Balance  Sheets are leasehold  mineral
rights  that are  regularly  evaluated  for  impairment  based on lease term and
drilling activity.

     The SEC  staff  referred  the issue of  whether  leasehold  mineral  rights
constitute  tangible or intangible assets to the Emerging Issues Task Force (the
"EITF") of the Financial Accounting Standard Board (the "FASB"). An EITF working
group was  created to  research  this issue and at the March 17 - 18,  2004 EITF
meeting,  the working group reached a consensus  that  leasehold  mineral rights
constituted  tangible  assets.  Ratification  of the  consensus  was  subject to
resolution of inconsistencies  between the characterization of mineral rights as
tangible  assets in the working  group  consensus  and the  characterization  of
mineral rights as intangible  assets in SFAS 141 and SFAS 142. On April 2, 2004,
the FASB issued for comment  proposed FASB Staff Positions (the "FSP") No. 141-a
and 142-a to eliminate the  inconsistencies  between the working group consensus
and the  provisions of SFAS 141 and SFAS 142. The FSP was finalized on April 30,
2004 and is effective for all reporting periods beginning after April 29, 2004.

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.
As such, the information contained herein should be read in conjunction with the
related  disclosures  in the  Company's  Annual Report on Form 10-K for the year
ended December 31, 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 future earnings gains or losses
on these instruments from changes in commodity prices or interest rates.

     Interest rate sensitivity.  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 March 31,  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
March 31, 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.

     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.  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.
