                       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 (SEC), 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 generally accepted accounting
principles 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 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 $320.7 million. The acquisition included estimated
proved reserves of 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 $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 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 $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 66 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 120.8 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.

    Divestitures -- During the six months ended June 30, 2001, Apache sold 66.2

properties, collecting cash of $238.7 million.


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 accounting treatment. Upon adoption, Apache
formally documented and designated all hedging relationships and


                                       7
   9

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
as part of the Fletcher acquisition. The carrying values at transition and June
30, 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 $1.1 million
during the first half of 2001. The time value of zero-cost collars at June 30,
2001 of $8.8 million will not trigger any cash receipts and will reduce to zero
as the options expire over the course of the next 24 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).

4. DEBT

    The Company's 9.25 percent notes due June 2002 were classified as long-term
debt in the accompanying consolidated balance sheet as the Company has the
ability and intent to refinance such amount on a long-term basis through
either the issuance of commercial paper or borrowing under the U.S. portion of
the global credit facility and the 364-day revolving credit facility.


5. RECENTLY ISSUED ACCOUNTING STANDARDS

    Apache's goodwill represents the excess of the purchase price over the
estimated fair value of the assets acquired and liabilities assumed in the
Fletcher and Repsol acquisitions (see Note 1). The goodwill is being amortized
on a straight-line basis over 20 years. In June 2001, the Financial Accounting
Standards Board issued SFAS No. 142, "Goodwill and Other Intangible Assets."
SFAS No. 142 establishes accounting and reporting standards requiring that
goodwill not be amortized, but rather tested at least annually for impairment.

    Apache will continue to record amortization of approximately $2.5 million
per quarter through December 31, 2001. The Company will adopt SFAS No. 142 on
January 1, 2002. No impairment of goodwill is currently anticipated; however,
the Company will continue to assess recoverability of goodwill on an ongoing
basis.


6.  SUPPLEMENTAL CASH FLOW INFORMATION

NON-CASH INVESTING AND FINANCING ACTIVITIES

    In January 2000, the Company acquired producing properties formerly owned by
a subsidiary of Repsol for cash, plus assumed liabilities of $29.8 million.

    In March 2001, the Company acquired substantially all of Repsol's oil and
gas concession interests in Egypt for cash and the assumption of certain
non-cash liabilities. The accompanying financial statements include the non-cash
amounts detailed in Note 1.

    In March 2001, the Company acquired subsidiaries of Fletcher for cash, 1.64
million restricted shares of common stock and the assumption of certain non-cash
liabilities. The accompanying financial statements include the non-cash amounts
detailed in Note 1.

    In June 2001, the Company repurchased 500,000 shares of its common stock at
an average price of $51.70, of which $9.4 million was settled and paid in July
2001.

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

OVERVIEW

    Driven by record oil and natural gas production, both second quarter and
first half results surged over their respective year-ago periods. Following are
the 2001 second quarter and first six months highlights:

- -   Record quarterly production of 154,718 barrels of oil per day (bbls/d) and
    1.2 billion cubic feet per day (Bcf/d) was 38 percent and 53 percent above
    comparable prior-year production rates. On an equivalent barrel basis, the
    46 percent growth from the second quarter of 2000 was the largest increase
    in nearly a decade. For the six-month period, production of 1.1 Bcf/d and
    138,198 bbls/d was 43 percent and 22 percent ahead of a year ago,
    respectively.

- -   Second quarter oil and natural gas production revenues of $796 million,
    climbed 63 percent from last year's comparable quarter, with second quarter
    oil production revenues climbing to a record $355.3 million, 34 percent
    above 2000, while gas revenues nearly doubled the year-ago period. Higher
    natural gas prices (up 31 percent) and production (up 53 percent) accounted
    for 69 percent of the increase in revenues relative to the comparable
    prior-year period. For the six-month period, oil and natural gas revenues
    surged 71 percent with natural gas contributing 82 percent to the increase.

- -   Income attributable to common stock of $478.2 million was $234.6 million (96
    percent) higher than the first half of 2000 and surpassed the results from
    Apache's second best full year.

- -   Basic net income per common share of $3.84 for the six-month period was
    $1.70, or 79 percent higher than last year's comparable period.

- -   Cash provided by operating activities of $1.1 billion increased 99 percent
    from the first half of 2000.

    The outlook for the second half of 2001 remains favorable despite declining
U.S. natural gas prices, recently trading around $3.00 per Mcf, and a leveling
off of crude oil prices.

    Commodity Prices -- Apache's average realized price for natural gas
increased $1.96 per thousand cubic feet (Mcf) from $2.80 per Mcf in the first
half of 2000 to $4.76 per Mcf in 2001, positively impacting revenues by $268.8
million. The average realized oil price decreased $.20 per barrel from $25.69
per barrel in the first half of 2000 to $25.49 per barrel in the comparable 2001
period, decreasing revenues by $4.3 million.

    Production -- Oil production increased 22 percent during the first half of
2001 when compared to the same period last year, which positively impacted
revenues by $111 million. The improvement was primarily the result of production
from acquisitions closed over the last 12 months, completion of the Gipsy/North
Gipsy development and first production from the Legendre field in Australia. Gas
production increased 43 percent during the first half of 2001 compared to the
same period last year, positively impacting revenues by $275.5 million. The
increase was primarily attributable to production from the acquisitions
discussed above and strong results from the Ladyfern area in Canada.


RESULTS OF OPERATIONS

    Apache reported 2001 second quarter income attributable to common stock of
$200.9 million compared to income of $139.3 million in the prior year. Basic net
income per common share of $1.60 for the second quarter of 2001, increased 31
percent over the $1.22 reported in 2000. A significant increase in oil and gas
production revenues was partially offset by higher DD&A expense, lease operating
costs, severance and other taxes and impairments of unproved property costs in
Poland and China.

    For the first half of 2001, income attributable to common stock of $478.2
million, or $3.84 per basic common share, compared to $243.5 million, or $2.14
per share, in the comparable year-earlier period. The increase resulted
primarily from increased oil and gas production revenues partially offset by
higher DD&A expense, lease operating costs, severance and other taxes and
impairments of unproved property costs in Poland and China.

   14
 For the second quarter of 2001, total revenues increased 65 percent to $800.4
million compared to $486.4 million in 2000. The increase was the result of a 53
percent increase in natural gas production, a 38 percent increase in oil
production and a 31 percent increase in the average realized price for natural
gas. Crude oil, including natural gas liquids, contributed 46 percent and
natural gas contributed 54 percent of oil and gas production revenues during the
second quarter of 2001.

    For the first six months of 2001, total revenues increased 71 percent to
$1.6 billion compared to $934.6 million for the same period in 2000. Revenues
from oil and gas production increased 71 percent over the same period in 2000,
with crude oil, including natural gas liquids, contributing 42 percent and
natural gas contributing 58 percent of oil and gas production revenues. The
increase in oil and gas production revenues was the result of a 70 percent
increase in the average realized gas price, a 43 percent increase in gas
production and a 22 percent increase in oil production.

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

SECOND QUARTER 2001 REVENUES COMPARED TO 2000

    Natural gas sales for the second quarter of 2001 totaled $426 million,
nearly double the second quarter of 2000. Average realized natural gas prices
increased 31 percent, positively impacting revenues by $65.5 million. The net
result of derivative instruments increased the Company's realized gas price by
$.07 per Mcf during the second quarter of 2001 and $.05 per Mcf for the same
period in 2000.

    Natural gas production increased 403.2 million cubic feet per day (MMcf/d),
or 53 percent, on a worldwide basis, favorably impacting revenues by $147.1
million. Production from properties acquired from Phillips in December 2000 and
Fletcher on March 27, 2001, and strong results from the Ladyfern area were the
primary contributors to the 196.7 MMcf/d gas production increase in Canada. The
U.S. increased 128.4 MMcf/d primarily the result of production from properties
acquired from Collins & Ware in June 2000 and Occidental in August 2000. Egypt
increased 65.6 MMcf/d due to production from properties acquired from Repsol in
March 2001.

    The Company's crude oil sales for the second quarter of 2001 totaled $355.3
million, a 34 percent increase from the second quarter of 2000, due to increased
production volumes. Average realized oil prices decreased $.64 per barrel,
negatively impacting revenues by $6.6 million. Realized losses from hedging
positions negatively impacted the Company's realized oil price by $.53 per
barrel during the second quarter of 2001 and $1.81 per barrel in the second
quarter of 2000.

    Oil production increased 38 percent compared to the prior year, favorably
impacting revenues by $96.9 million. Canada increased 17,049 bbls/d, Egypt
increased 14,723 bbls/d and the U.S. increased 4,112 bbls/d, primarily due to
production from properties acquired from Phillips, Fletcher, Repsol, Collins &
Ware and Occidental as mentioned above. Completion of the Gipsy/North Gipsy
development and first production from the Legendre field in Australia were the
primary contributors to the 6,313 bbls/d increase in Australia.

    Revenue from the sale of natural gas liquids totaled $14.8 million for the
second quarter of 2001, compared to $9.8 million for the second quarter of 2000
in response to a six percent improvement in realized prices and a 43 percent
increase in natural gas liquids production.

YEAR-TO-DATE 2001 REVENUES COMPARED TO 2000

    Natural gas sales for the first half of 2001 of $928.5 million increased
$544.3 million, or 142 percent, from the same period of 2000. Average realized
natural gas prices increased 70 percent, positively affecting revenues by $268.8
million. U.S. natural gas production, which comprised 58 percent of the
Company's worldwide gas production, sold at an average price of $5.56 per Mcf,
85 percent higher than in 2000, positively impacting natural gas revenues by
$224.3 million. The net result of derivative instruments impacted the Company's
realized gas price by a negative $.04 per Mcf during the first half of 2001 and
a positive $.03 per Mcf during the same period of 2000.

    Production from properties acquired from Phillips and Fletcher and strong
results from the Ladyfern area were the primary contributors to the 126.8 MMcf/d
gas production increase in Canada. The U.S. increased 139.9 MMcf/d due to the
production from properties acquired from Collins & Ware and Occidental, and
Egypt increased 38.2 MMcf/d due to producing properties acquired from Repsol.

    For the first half of 2001, oil revenues of $637.6 million increased $106.8
million, or 20 percent, from the same period in 2000 due to improved production.
On a worldwide basis, average oil prices decreased $.20 per barrel, or one
percent, to $25.49 per barrel negatively impacting oil revenues by $4.3 million.
Realized losses from hedging positions negatively impacted the Company's
realized oil price by $.62 per barrel during the first half of 2001 and $1.80
per barrel during the first half of 2000.

    Oil production increased 11,779 bbls/d in Canada, 4,971 bbls/d in the U.S.
and 4,111 bbls/d in Egypt, primarily driven by production from properties
acquired from Phillips, Fletcher, Repsol, Collins & Ware and Occidental as
mentioned above. Completion of the Gipsy/North Gipsy development and first
production from the Legendre field in Australia were the primary contributors to
the 3,830 bbls/d increase in Australia.

    Natural gas liquids revenues for the first six months of 2001 of $31.5
million increased $12.2 million, or 63 percent, from the same period in 2000.
Natural gas liquids prices increased by $2.49 per barrel, or 14 percent and
natural gas liquids production increased 2,673 barrels per day, or 44 percent.

OPERATING EXPENSES

    The Company's DD&A expense for the second quarter and first six months of
2001 increased $72.3 million and $112.7 million, respectively, over the
comparable periods of 2000. On an equivalent barrel (Boe) basis, full cost DD&A
expense increased $.23 per Boe, from $5.69 per Boe in the second quarter of 2000
to $5.92 per Boe in 2001. For the six months ended June 30, 2001, the full cost
DD&A rate increased $.37 per Boe, from $5.62 per Boe to $5.99 per Boe. For the
first six months of 2001, the full cost DD&A rate for the U.S. increased $.40
per Boe from $6.09 per Boe to $6.49 per Boe, primarily the result of the
acquisition of the Occidental properties in August 2000 and rising U.S. drilling
costs. The acquisition of the Phillips properties in December 2000 carry higher
DD&A costs, which helped push the full cost DD&A rate in Canada from $5.49 per
Boe to $5.96 per Boe.

    During the second quarter of 2001, the Company recorded a nonrecurring $65
million impairment ($41 million after-tax) of unproved property costs in Poland
and China.

    Lease operating expense (LOE) for the second quarter and first six months of
2001 increased $42.9 million and $71.6 million, respectively, over the
comparable periods of 2000. On an equivalent barrel basis, LOE increased $.50
per Boe to $3.11 per Boe in the second quarter and $.55 per Boe to $3.24 per Boe
in the first six months of 2001 compared to the same periods in the prior year.
The higher costs were partially attributable to the acquisition of Canadian and
offshore oil properties, which carried a higher LOE per Boe rate than the
Company's base production. Increased workover activities in the U.S. and Canada
and rising fuel cost for electric power also contributed to the increase. The
workovers accelerated production, allowing Apache to maximize the benefits of
high oil and gas prices. Severance and other taxes increased $9.1 million in the
second quarter and $21.5 million in the first six months of 2001 primarily 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. Also contributing
to the increase were higher effective production tax rates due to a loss of
incentives in Oklahoma and an increase in Canadian Large Corporation Tax due to
the added production from the Fletcher acquisition properties.

    G&A expense in the second quarter and first six months of 2001 increased
$6.6 million or 40 percent, and $12.3 million or 39 percent, respectively, from
a year ago. The Company's overall infrastructure was enlarged to properly handle
increased responsibilities associated with recent producing property
acquisitions. On an equivalent barrel basis, G&A expenses increased only $.04
per Boe, to $.74 per Boe, for the first half of 2001 as compared to $.70 per Boe
for the same period in 2000.

    Net financing costs for the second quarter and first six months of 2001
increased $7.9 million, or 30 percent, and $8.9 million, or 16 percent,
respectively, compared to a year ago. This increase is primarily due to higher
gross interest expense, the result of a higher average outstanding debt balance
related to acquisition activity in the second half of 2000 and the first quarter
of 2001.


MARKET RISK

COMMODITY 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.

INTEREST RATE RISK

    The Company considers its interest rate risk exposure to be minimal as a
result of fixing interest rates on approximately 58 percent of the Company's
debt. At June 30, 2001, total debt included $1.1 billion of floating-rate debt.
As a result, Apache's annual interest cost in 2001 will fluctuate based on
short-term interest rate on approximately 42 percent of it total debt
outstanding at June 30, 2001. The Company did not have any open derivative
contracts relating to interest rates at June 30, 2001.

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 flow 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.

    Capital Expenditures - A summary of oil and gas capital expenditures during
the first six months of 2001 and 2000 is presented below:

    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 66 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 restricted
shares of Apache common 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 120.8 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. 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 half of 2001 totaled $1.1 billion, an
increase of 99 percent from $547.2 million in the first half of 2000. This
increase was primarily due to higher oil and gas revenues generated from
properties acquired throughout 2000 and the first quarter of 2001 and higher
realized gas prices as compared to last year.

    Liquidity -- The Company had $129.3 million in cash and cash equivalents on
hand at June 30, 2001, up from $37.2 million at December 31, 2000. Apache's
ratio of current assets to current liabilities at June 30, 2001 was 1.03
compared to 1.14 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 June 30, 2001, Apache's available
borrowing capacity under its global credit facility and 364-day credit facility
was $463.4 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:

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

- -   Drilling exploration wells to add new reserves.

- -   Acquiring properties to which we can add 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 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.
