                       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.

     Divestitures - During the three months ended March 31, 2001, Apache sold

properties, collecting cash of $128.7 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


                                       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).

5. BUSINESS SEGMENT INFORMATION

     Apache has five reportable segments which are primarily in the business of
natural gas and crude oil exploration and production. The Company evaluates
performance based on profit or loss from oil and gas operations before income
and expense items incidental to oil and gas operations and income taxes.
Apache's reportable segments are managed separately because of their geographic
locations. Financial information by operating segment is presented below:

6. SUPPLEMENTAL GUARANTOR INFORMATION

     Prior to 2001, Apache Finance Pty Ltd. (Apache Finance Australia) was a
finance subsidiary of Apache with no independent operations. In this capacity,
it issued approximately $270 million of publicly traded notes that are fully and
unconditionally guaranteed by Apache and, beginning in 2001, Apache North
America, Inc. The guarantors of Apache Finance Australia have joint and
severable liability. Similarly, Apache Finance Canada Corporation (Apache
Finance Canada) was also a finance subsidiary of Apache and had issued
approximately $300 million of publicly traded notes that were fully and
unconditionally guaranteed by Apache.

     Generally, the issuance of publicly traded securities would subject those
subsidiaries to the reporting requirements of the Securities and Exchange
Commission (SEC). Since these subsidiaries had no independent operations and
qualified as "finance subsidiaries", they were exempted from these requirements.

     During 2001, Apache contributed stock of its Australian and Canadian
operating subsidiaries to Apache Finance Australia and Apache Finance Canada,
respectively. As a result of these contributions, they no longer qualify as
finance subsidiaries. As allowed by the SEC rules, the following condensed
consolidating financial statements are provided as an alternative to filing
separate financial statements.

     Each of the Company's presented in the condensed consolidating financial
statements has been fully consolidated in Apache Corporation's consolidated
financial statements. As such, the condensed consolidating financial statements
should be read in conjunction with the financial statements of Apache
Corporation and subsidiaries and notes thereto of which this note is an integral
part.
