                       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.

     The Fletcher and Repsol purchase prices were allocated to the assets
acquired and liabilities assumed based upon their fair values on the date of
acquisition, as follows:

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



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.

7.   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:

8.   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 companies 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.
