                       APACHE CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


     These financial statements have been prepared by Apache Corporation (Apache
or the Company) without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission, and reflect all adjustments which are, in
the opinion of management, necessary for a fair statement of the results for the
interim periods, on a basis consistent with the annual audited financial
statements. All such adjustments are of a normal recurring nature. Certain
information, accounting policies, and footnote disclosures normally included in
financial statements prepared in accordance with accounting principles generally
accepted in the United States have been omitted pursuant to such rules and
regulations, although the Company believes that the disclosures are adequate to
make the information presented not misleading. These financial statements should
be read in conjunction with the financial statements and the summary of
significant accounting policies and notes thereto included in the Company's most
recent annual report on Form 10-K.

     Change in Accounting Principle - In December 2000, the staff of the
Securities and Exchange Commission (SEC) announced that commodity inventories
should be carried at cost, not market value, despite longstanding industry
practice. As a result, Apache changed its accounting for crude oil inventories
in the fourth quarter of 2000, retroactive to the beginning of the year, and
recognized a non-cash cumulative-effect charge to earnings effective January 1,
2000. Quarterly results for 2000 have been restated to reflect this change in
accounting.


1.       ACQUISITIONS AND DIVESTITURES

    Acquisitions - In June 2000, Apache completed the acquisition of long-lived
producing properties in the Permian Basin and South Texas from Collins & Ware,
Inc. (Collins & Ware) for approximately $320.7 million. The acquisition included
estimated proved reserves of approximately 83.7 million barrels of oil
equivalent (MMboe) as of the acquisition date. One-third of the reserves are
liquid hydrocarbons.

    In August 2000, Apache completed the acquisition of a Delaware limited
liability company (LLC) owned by subsidiaries of Occidental Petroleum
Corporation (Occidental) and the related natural gas production for
approximately $321.2 million, plus future payments of approximately $44.0
million over four years. The Occidental properties are located in 32 fields on
93 blocks on the Outer Continental Shelf of the Gulf of Mexico. The acquisition
included estimated proved reserves of approximately 53.1 MMboe as of the
acquisition date.

     In December 2000, Apache completed the acquisition of Canadian properties
from Canadian affiliates of Phillips Petroleum Company (Phillips) for
approximately $490.3 million. The acquisition included estimated proved reserves
of approximately 70.0 MMboe as of the acquisition date. The properties comprise
approximately 212,000 net developed acres and 275,000 net undeveloped acres, 786
square miles of 3-D seismic and 4,155 miles of 2-D seismic located in the Zama
area of Northwest Alberta. The assets also include three sour gas plants with a
total capacity of 150 million cubic feet (MMcf) per day, 13 compressor stations
and 150 miles of owned and operated gas gathering lines.

     On March 22, 2001, Apache completed the acquisition of substantially all of
Repsol YPF's (Repsol) oil and gas concession interests in Egypt for
approximately $446.9 million in cash, subject to normal post closing
adjustments. The properties include interests in seven Western Desert
concessions and have estimated proved reserves of 68 MMboe as of the acquisition
date. The Company already holds interests in five of the seven concessions.

     On March 27, 2001, Apache completed the acquisition of subsidiaries of
Fletcher Challenge Energy (Fletcher) for approximately $465.0 million in cash
and 1.64 million restricted shares of Apache common stock issued to Shell
Overseas Holdings (valued at $61.04 per share), subject to normal post closing
adjustments. The transaction included properties located in Canada's Western
Sedimentary Basin and in Argentina and estimated proved reserves of 118.8 MMboe
as of the acquisition date. Apache assumed a liability of $103.5 million
representing the fair value of derivative instruments and fixed-price commodity
contracts entered into by Fletcher.

2.       DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

     Apache periodically enters into commodity derivatives contracts to manage
its exposure to oil and gas price volatility. Commodity derivatives contracts,
which are usually placed with major financial institutions that the Company
believes are minimal credit risks, may take the form of futures contracts, swaps
or options. The oil and gas reference prices upon which these commodity
derivatives contracts are based reflect various market indices that have a high
degree of historical correlation with actual prices received by the Company.
Realized gains and losses from the Company's price risk management activities
are recognized in oil and gas production revenues when the associated production
occurs and the resulting cash flows are reported as cash flows from operating
activities.

     Effective January 1, 2001, Apache adopted Statement of Financial Accounting
Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging
Activities". SFAS No. 133 establishes accounting and reporting standards
requiring that all derivative instruments (including derivative instruments
embedded in other contracts), as defined, be recorded in the balance sheet as
either an asset or liability measured at fair value and requires that changes in
fair value be recognized currently in earnings unless specific hedge accounting
criteria are met. Hedge accounting treatment allows unrealized gains and losses
to be deferred in other comprehensive income (for the effective portion of the
hedge) until such time as the forecasted transaction occurs, and requires that a
company formally document, designate, and assess the effectiveness of derivative
instruments that receive hedge


                                       7

accounting treatment. Upon adoption, Apache formally documented and designated
all hedging relationships and verified that its hedging instruments are
effective in offsetting changes in actual prices received by the Company. Such
effectiveness is monitored at least quarterly and any ineffectiveness is
reported in other revenues (losses) in the statement of consolidated operations.

     Apache's derivative positions break down into three general categories:
advances from gas purchasers, Apache hedging activity and derivatives inherited
from Fletcher. The fair values at transition and March 31, 2001 are summarized
below:

     On the transition date, January 1, 2001, Apache recognized a derivative
asset of $121.5 million reflecting the fair value of gas price swaps entered
into in connection with certain advance payments received from gas purchasers in
1998 and 1997. Apache also recognized a derivative liability of $121.5 million
as an embedded derivative in the contracts under which the advance payments were
received. The liability reflects the obligation to deliver gas at market prices
in excess of the contractual prices determined at the inception of these
transactions.

     The balance of Apache's derivative instruments relate to cash flow hedges
on forecasted oil and gas sales, primarily entered into as the result of
Apache's acquisition hedging strategy. On the transition date, the fair value of
these derivative instruments represented a net liability of $116.2 million. The
Company incurred a charge to earnings for minor ineffectiveness of $1.3 million
during the first quarter of 2001. The time value of zero-cost collars at March
31, 2001 ($44.6 million) will not trigger any cash payments and will erode to
zero as the options expire over the course of the next 27 months.

     In connection with the Fletcher acquisition, Apache assumed liabilities for
derivative instruments (fixed-price swaps and put options) and fixed-price
physical contracts entered into by Fletcher. The $103.5 million fair value on
the closing date was recorded as a cost of the Fletcher acquisition (see Note
1).

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

OVERVIEW

     Strong product prices combined with record oil and natural gas production
both contributed to our seventh consecutive quarterly increase in earnings and
oil and gas revenues. Following are highlights for the first three months of
2001:

o    Record oil and natural gas production revenues of $801.6 million, climbed
     80 percent from last year's comparable quarter and nine percent from the
     record fourth quarter of 2000. Higher natural gas prices (up 124 percent)
     and production (up 33 percent) accounted for 93 percent of the increase in
     revenues relative to the comparable prior-year period.

o    Income attributable to common stock of $277.3 million was $173.1 million
     (166 percent) higher than the first quarter of 2000.

o    Record basic net income per common share of $2.24 was $1.32, or 143 percent
     higher than last year's comparable quarter and $.20 higher than the fourth
     quarter of 2000.

o    Cash provided by operating activities of $642.5 million surpassed the
     half-billion dollar threshold for the second consecutive quarter and
     increased 165 percent from the first quarter of 2000.

o    Record production of 987.7 million cubic feet of gas per day (MMcf/d) and
     121,496 barrels of oil per day (bbls/d) was 33 percent and six percent
     ahead of a year ago, respectively, and topped fourth quarter 2000 averages
     of 934.5 MMcf/d and 115,235 bbls/d.

o    On the regulatory front, following Apache's involvement, the FASB reversed
     its initial position concerning changes in the time value component of
     derivative instruments, in line with Apache's recommendation that such
     changes be recorded in the equity section of the balance sheet rather than
     through the income statement.

     Apache's outlook for the remainder of 2001 is favorable given the current
indications for continuing strong product prices and rising production from the
Fletcher and Repsol acquisitions which contributed to first quarter results for
only four and nine days, respectively. Also, augmenting future oil and gas
production will be completion of the Legendre and Simpson developments in
Australia, scheduled for the second quarter, as well as the full impact of gas
production from the Ladyfern area in Canada.

     Commodity Prices - Apache's average realized oil price increased $.30 per
barrel from $25.51 per barrel in the first quarter of 2000 to $25.81 per barrel
in the comparable 2001 period, increasing revenues by $3.2 million. The average
realized price for natural gas increased $3.13 per thousand cubic feet (Mcf)
from $2.52 per Mcf in the first quarter of 2000 to $5.65 per Mcf in 2001,
positively impacting revenues by $211.8 million.

     Production - Gas production increased 33 percent during the first quarter
of 2001 when compared to the same period last year. The increase in gas
production positively impacted revenues by $119.9 million. Oil production
increased six percent during the first quarter of 2001 when compared to the same
period last year. The increase in oil production positively impacted revenues by
$13.3 million. The increase in both oil and gas production was driven by the
Collins & Ware and Occidental acquisitions in the U.S. and the Phillips
acquisition in Canada during 2000. Successful drilling results in the Ladyfern
area in Canada and completion of the Gipsy/North Gipsy development in Australia
also contributed to the increase in gas production.


RESULTS OF OPERATIONS

     Apache reported income attributable to common stock of $277.3 million in
the first quarter of 2001 versus $104.2 million in the prior year. Basic net
income per common share of $2.24 for the first quarter of 2001 was 143 percent
higher than the basic net income per common share of $.92 in 2000. The
significant increase in oil and gas production revenues was partially offset by
higher operating expenses.


                                       11
   13


     For the first quarter of 2001, revenues increased 77 percent to $795.1
million compared to $448.2 million in 2000, driven by a 194 percent increase in
gas production revenues and a six percent increase in oil production revenues.
The increase in oil and gas production revenues was primarily the result of a
124 percent increase in the average realized price for natural gas, a 33 percent
increase in natural gas production and a six percent increase in oil production.
Crude oil, including natural gas liquids, contributed 37 percent and natural gas
contributed 63 percent of oil and gas production revenues in the first quarter
of 2001.

     Volume and price information for the Company's oil and gas production is
summarized in the following table:

FIRST QUARTER 2001 COMPARED TO FIRST QUARTER 2000

     Natural gas sales for the first quarter of 2001 totaled $502.6 million, 194
percent higher than the first quarter of 2000. Average realized natural gas
prices increased 124 percent, positively affecting revenue by $211.8 million.
Apache realized average natural gas price increases in the U.S. of 153 percent,
from $2.62 per Mcf in the first quarter 2000 to $6.63 per Mcf in the same period
in 2001. The United States represented 64 percent of total natural gas
production for the first quarter of 2001. The net result of derivative
instruments decreased the Company's realized gas price by less than three
percent, or $.16 per Mcf, during the first quarter of 2001 and increased the
Company's realized gas price by $.02 per Mcf during the first quarter of 2000.

     Natural gas production increased 244 MMcf/d, or 33 percent, on a worldwide
basis, favorably impacting revenue by $119.9 million. Natural gas production in
the U.S. increased 31 percent primarily due to production from the Collins &
Ware and Occidental property acquisitions in 2000. Initial production from the
Ladyfern area and the Phillips' properties acquired in late December 2000, were
the primary sources of the 56.1 MMcf/d increase in Canada.

     The Company's crude oil sales for the first quarter of 2001 totaled $282.3
million, a six percent increase from the first quarter of 2000, due primarily to
higher production. The Company's realized price for sales of crude oil in the
first quarter of 2001 increased $.30 per barrel, resulting in an increase in
revenue of $3.2 million compared to the same period in 2000. Realized hedging
losses negatively impacted the Company's realized oil price by less than three
percent, or $.74 per barrel, during the first quarter of 2001 and $1.79 during
the first quarter of 2000.

     First quarter 2001 oil production increased six percent compared to the
prior year primarily from an 11 percent increase in oil production in the U.S.
and a 47 percent increase in Canada, resulting in a $13.3 million increase in
revenue compared to the same period in 2000. The U.S. oil production increase in
the first quarter of 2001 was primarily due to production from the Collins &
Ware and Occidental property acquisitions in 2000. Production from properties
acquired from Phillips in late December 2000 was the primary source of the
increased production in Canada.

     Revenue from the sale of natural gas liquids totaled $16.8 million for the
first quarter of 2001, compared to $9.5 million for the first quarter of 2000.
Natural gas liquids production increased 2,725 barrels per day, or 45 percent,
and natural gas liquids prices increased $4 per barrel, or 23 percent.

OPERATING EXPENSES

     The Company's DD&A expense for the first quarter of 2001 totaled $172.5
million, compared to $132.1 million for the same period in 2000. On an
equivalent barrel basis, full cost DD&A expense increased $.51 per barrel of oil
equivalent (boe), from $5.56 per boe in the first quarter of 2000 to $6.07 per
boe in 2001. The DD&A rate for the U.S. increased $.36 per boe from $6.04 per
boe to $6.40 per boe, primarily the result of the acquisition of the Occidental
properties in August 2000 and rising U.S. drilling rig costs. The acquisition of
the Phillips' properties in December 2000, which carry higher DD&A costs, helped
push the DD&A rate in Canada from $5.48 per boe to $6.08 per boe. The DD&A rate
in Egypt increased by $1.26 per boe, from $4.89 per boe to $6.15 per boe
primarily because of higher projected future development costs.

     Lease operating expense (LOE) increased 47 percent from $61.5 million in
the first quarter of 2000 to $90.1 million for the same period in 2001. On an
equivalent barrel basis, LOE increased from $2.76 per boe in the first quarter
of 2000 to $3.39 per boe in the first quarter of 2001. Higher costs were
partially attributable to the acquisition of Canadian and offshore oil
properties, which carried a higher LOE per boe rate than our base production.
Also adding to the rise were increased workover activities in the U.S. and
Canada and rising fuel costs for electric power. The workovers accelerated
production, allowing Apache to maximize the benefits of high oil and gas prices.
Severance and other taxes increased from $9.0 million in the first quarter of
2000 to $21.3 million in the first quarter of 2001 due to the impact of higher
oil and gas prices on severance taxes, which generally are based on a percentage
of oil and gas production revenues.

     G&A expense in the first quarter of 2001 increased $5.7 million, or 39
percent, from a year ago primarily due to our enlarged overall infrastructure to
properly handle increased responsibilities associated with recent producing
property acquisitions. On an equivalent barrel basis, G&A expense for the first
three months of 2001 increased $.11 per boe, to $.77 per boe compared to $.66
per boe for the same period in 2000.


                                       13
   15


     Net financing costs for the first quarter of 2001 increased $1.0 million,
or three percent, from the prior year primarily due to higher gross interest
expense. Gross interest expense increased $3.1 million due to a higher average
outstanding debt balance attributable to acquisitions during 2000.


MARKET RISK

     The Company's major market risk exposure continues to be the pricing
applicable to its oil and gas production. Realized pricing is primarily driven
by the prevailing worldwide price for crude oil and spot prices applicable to
its United States and Canadian natural gas production. Historically, prices
received for oil and gas production have been volatile and unpredictable. Price
volatility is expected to continue. See "Results of Operations" above.

     The information set forth under "Commodity Risk" in Item 7A of the
Company's annual report on Form 10-K for the year ended December 31, 2000, is
incorporated herein by reference.


CASH FLOW, LIQUIDITY AND CAPITAL RESOURCES

CAPITAL COMMITMENTS

     Apache's primary cash needs are for exploration, development and
acquisition of oil and gas properties, repayment of principal and interest on
outstanding debt, payment of dividends and capital obligations for affiliated
ventures. Apache budgets capital expenditures based upon projected cash flows
and routinely adjusts its capital expenditures in response to changes in oil and
natural gas prices and corresponding changes in cash flow. The Company cannot
accurately predict future oil and gas prices.

     On March 22, 2001, Apache completed the acquisition of substantially all of
Repsol's oil and gas concession interests in Egypt for approximately $446.9
million in cash, subject to normal post-closing adjustments. The properties
include interests in seven Western Desert concessions and have estimated proved
reserves of 68 MMboe as of the acquisition date. The Company already holds
interests in five of the seven concessions. The transaction was funded through
the issuance of commercial paper.

     On March 27, 2001, Apache completed the acquisition of subsidiaries of
Fletcher for approximately $465.0 million in cash and 1.64 million shares of
Apache stock (valued at $61.04 per share), subject to normal post-closing
adjustments. The transaction included properties located in Canada's Western
Sedimentary Basin and in Argentina and have estimated proved reserves of 118.8
MMboe as of the acquisition date. Apache assumed a liability of $103.5 million
representing the fair value of derivative instruments and fixed-price commodity
contracts entered


                                       14

into by Fletcher. The cash portion of the acquisition was funded through the
issuance of commercial paper, as well as advances under the Canadian portion of
the global credit facility.

CAPITAL RESOURCES AND LIQUIDITY

     Net Cash Provided by Operating Activities - Apache's net cash provided by
operating activities during the first three months of 2001 totaled $642.5
million, an increase of 165 percent from $242.2 million in the first three
months of 2000. This increase was primarily due to higher oil and gas revenues
generated from properties acquired throughout 2000 and higher realized oil and
gas prices as compared to last year.

     Liquidity - The Company had $106.8 million in cash and cash equivalents on
hand at March 31, 2001, up from $37.2 million at December 31, 2000. Apache's
ratio of current assets to current liabilities at March 31, 2001 was .9:1
compared to 1.14:1 at December 31, 2000.

     Apache believes that cash on hand, net cash generated from operations, and
unused committed borrowing capacity under its global credit facility will be
adequate to satisfy the Company's financial obligations to meet future liquidity
needs for the foreseeable future. As of March 31, 2001, Apache's available
borrowing capacity under its global credit facility and 364-day credit facility
was $356.4 million.


FUTURE TRENDS

     Apache's strategy is to increase its oil and gas reserves, production, cash
flow and earnings through a balanced growth program that involves:

o    Exploiting our existing asset base through workovers and development wells
     to increase productive capacity.

o    Drilling exploration wells to add new reserves.

o    Acquiring properties to which we can add incremental value.

EXPLOITING OUR EXISTING ASSET BASE THROUGH WORKOVERS AND DEVELOPMENT WELLS TO
INCREASE PRODUCTIVE CAPACITY

     Apache seeks to maximize the value of our existing asset base by conducting
workovers and development drilling within known limits of previously recognized
reservoirs to increase productive capacity and/or the efficiency or rate of
existing fields.

DRILLING EXPLORATION WELLS TO ADD NEW RESERVES

     Apache seeks to add new reserves through drilling exploratory wells in all
our regions. Higher risk, higher reward exploration is conducted in Canada and
select international core areas. Our international investments and exploration
activities are a significant component of our long-term growth strategy. They
complement our United States operations, which are more development oriented.

ACQUIRING PROPERTIES TO WHICH WE CAN ADD VALUE

     Apache seeks to purchase reserves at reasonable prices by generally
avoiding auction processes where we are competing against other buyers. Our aim
is to follow each acquisition with a cycle of reserve enhancement, property
consolidation and cash flow acceleration, facilitating asset growth and debt
reduction.

     A critical component in implementing our three-pronged growth strategy is
maintenance of significant financial flexibility. We are committed to preserving
a strong balance sheet and credit position that gives us the foundation required
to pursue our growth initiatives.


FORWARD-LOOKING STATEMENTS AND RISK

     Certain statements in this report, including statements of the future
plans, objectives, and expected performance of the Company, are forward-looking
statements that are dependent upon certain events, risks and uncertainties that
may be outside the Company's control, and which could cause actual results to
differ materially from those anticipated. Some of these include, but are not
limited to, the market prices of oil and gas, economic and


                                       15
   17


competitive conditions, inflation rates, legislative and regulatory changes,
financial market conditions, political and economic uncertainties of foreign
governments, future business decisions, and other uncertainties, all of which
are difficult to predict.

     There are numerous uncertainties inherent in estimating quantities of
proved oil and gas reserves and in projecting future rates of production and the
timing of development expenditures. The total amount or timing of actual future
production may vary significantly from reserves and production estimates. The
drilling of exploratory wells can involve significant risks, including those
related to timing, success rates and cost overruns. Lease and rig availability,
complex geology and other factors can affect these risks. Although Apache makes
use of futures contracts, swaps, options and fixed-price physical contracts to
mitigate risk, fluctuations in oil and gas prices, or a prolonged continuation
of low prices, may substantially adversely affect the Company's financial
position, results of operations and cash flows.
