                       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.




                                       6

     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:

     On August 23, 2001, Apache completed the acquisition of properties located
in Texas, Oklahoma and New Mexico with estimated proved reserves of 9.2 MMboe as
of the acquisition date for approximately $42.5 million in cash and the
assumption of certain liabilities, representing the fair value of derivative
instruments of $9.2 million, subject to normal post closing adjustments.

     Divestitures - During the nine months ended September 30, 2001, Apache sold
66.4 MMboe of proved reserves from largely marginal United States and Canadian
properties, collecting cash of $233.3 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




                                       7


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 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 and August 23, 2001 acquisitions. The carrying values at
transition and September 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
time value of zero-cost collars at September 30, 2001 was $23.9 million.



                                       8

     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).

     In connection with the acquisition completed August 23, 2001, Apache
assumed liabilities for derivative instruments (fixed-price swaps and put
options) with a fair value of $9.2 million on the closing date, which was
recorded as a cost of the acquisition (see Note 1).

     In early November 2001, due to credit issues surrounding the derivative
market, Apache began to close out substantially all of its hedging positions.
The Company does not expect to recognize a material gain or loss from the
expected proceeds received in connection with termination of these positions.

4.   DEBT

     The Company's 9.25 percent notes due June 2002 are 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.   STOCK DIVIDEND

     On September 13, 2001, the Company's Board of Directors declared a 10
percent stock dividend payable on January 21, 2002 to shareholders of record on
December 31, 2001. No fractional shares will be issued and payments will be made
in lieu of fractional shares. In connection with the dividend, a
reclassification was made to transfer $545 million from retained earnings to
additional paid-in-capital in the accompanying consolidated balance sheet as of
September 30, 2001. The following pro forma information shows the effect on the
Company's consolidated results of operations as if the stock dividend were made
on January 1, 2000.

6.   MINORITY INTEREST

     In August 2001, Apache entered into a series of financing transactions,
described below, to raise a total of $440.7 million for investments, to pay down
existing debt and increase financial flexibility.

     Apache contributed interests in various fields valued at $923 million to
new subsidiaries in connection with the financing transactions. Additionally, on
August 7, 2001, Apache purchased $116.7 million in U.S. Government Agency Notes,
maturing in October 2002, which were contributed to the subsidiaries. Unrelated
institutional investors contributed $443 million ($440.7 million, net of
issuance costs) to the various subsidiaries in exchange for preferred stock of
the subsidiaries and a limited partner interest in one of the entities. The
third party investors are entitled to receive a weighted average return of 123
basis points above the prevailing LIBOR interest rate. The preferred and limited
partner interests are repayable from the assets of the subsidiaries with limited
recourse to Apache.

     The assets, liabilities and operations of the subsidiaries are included in
Apache's consolidated financial statements at historical costs, with the
preferred and limited partner interests of the subsidiaries reflected as a
minority interest. The U.S. Government Agency Notes are accounted for as
"held-to-maturity" securities shown as long-term investments in the accompanying
balance sheet.

7.   RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS
No. 142, "Goodwill and Other Intangible Assets." SFAS No. 142 establishes
accounting and reporting standards discontinuing goodwill amortization and
requiring a periodic review for impairments. 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 currently is being amortized on a straight-line basis over
20 years. Apache will continue to record amortization of approximately $2.5
million per quarter through December 31, 2001. The



                                       10


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.

     In June 2001, the FASB issued SFAS No. 143 "Accounting for Asset Retirement
Obligations." The statement requires entities to record the fair value of legal
obligations associated with the retirement of tangible long-lived assets in the
period in which it is incurred. When the liability is initially recorded, the
entity increases the carrying amount of the related long-lived asset. Over time,
accretion of the liability is recognized each period, and the capitalized cost
is depreciated over the useful life of the related asset. Upon settlement of the
liability, the entity either settles the obligation for its recorded amount or
incurs a gain or loss upon settlement. SFAS No. 143 is effective for fiscal
years beginning after June 15, 2002, with earlier adoption encouraged. The
Company is currently assessing the impact of adopting SFAS No. 143 on its
financial condition and results of operations and has not determined the timing
of adoption.

8.   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 August 2001, the Company acquired properties located in Texas, Oklahoma
and New Mexico for cash and the assumption of certain non-cash liabilities. The
accompanying financial statements include the non-cash amounts detailed in Note
1.

10.  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,
