     These charts reflect our estimated production before and after the pending
BP transactions by core areas. Percentages are calculated by using Apache's
January 2003 estimated daily production rate and our estimate of the daily
production rate from the BP assets for 2003, which we used to value the assets
that we have agreed to acquire. The estimated production attributable to the
pending BP transactions is based solely on our internal estimates and has not
been reviewed by our independent reserve engineers. There is no assurance that
the pending BP transactions will be completed or that our estimate of production
will prove correct.

                               APACHE CORPORATION

     Apache Corporation is an independent energy company that, directly and
through subsidiaries, explores for, acquires and develops oil and gas reserves
and produces natural gas, crude oil, condensate and natural gas liquids. In
North America, our exploration and production interests are focused on the Gulf
of Mexico, the Anadarko Basin, the Permian Basin, the Gulf Coast and the Western
Sedimentary Basin of Canada. Outside North America, we currently have
exploration and production interests offshore Western Australia, Argentina and
in Egypt and exploration interests in Poland and offshore The People's Republic
of China.

     Through September 30, 2002, our average daily production was:

      --   162 Mbbls of crude oil, condensate and natural gas liquids; and

      --   1,082 MMcf of natural gas.

     As of December 31, 2001, our worldwide proved reserves totaled 1,267 MMboe,
including:

      --   599 MMbbls of crude oil, condensate and natural gas liquids; and

      --   4,005 Bcf of natural gas.

STRATEGY

     Our strategy is to increase our oil and gas reserves, production, cash flow
and earnings through a balanced growth program that involves:

      --   exploiting our existing asset base;

      --   acquiring properties to which we can add incremental value; and

      --   investing in high-potential exploration prospects.

     Exploiting Our Existing Asset Base.  We seek to maximize the value of our
existing asset base by increasing production and reserves while controlling per
unit operating costs. In order to achieve these objectives, we rigorously
examine our operations to reduce costs, identify production enhancement
initiatives such as workovers and recompletions employing new technology, and
divest marginal and non-strategic properties.

     Acquiring Properties To Which We Can Add Incremental Value.  Generally, we
seek to purchase reserves at appropriate prices by avoiding auction processes
where we are competing with other buyers and timing our acquisitions to avoid
the peak of the price cycle. Our aim is to follow each acquisition with a cycle
of reserve enhancement, property consolidation and cash flow acceleration,
thereby facilitating asset growth and debt reduction. During the past decade, we
have consistently succeeded in adding value to acquired properties through this
strategy. We acquired 254 MMboe and 213 MMboe of proved reserves for $1.3
billion and $0.9 billion in 2000 and 2001, respectively. In addition, the
acquisitions included $94 million of production, processing and transportation
facilities in 2000, and $146 million of such facilities and $197 million of
goodwill in 2001. In 2002, we acquired an estimated 49 MMboe of proved reserves
for approximately $355 million. We believe that the current environment is
favorable for possible additional acquisitions. We

                                       S-1


continue to evaluate attractive opportunities. Any future acquisitions would be
subject to a number of conditions, including conditions beyond our control, and
there can be no assurance that we will enter into or actually consummate any
such transactions.

     Investing In High-Potential Exploration Prospects.  Our international
investments and exploration activities are a significant component of our
long-term growth strategy. They complement our North American operations, which
are more development oriented. We seek to concentrate our exploratory
investments in a select number of international areas and to become a dominant
operator in those regions. We believe that these investments, although
higher-risk, offer the potential for significant reserve additions.

     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 to give us the foundation required to
pursue our growth initiatives.

RECENT DEVELOPMENTS

     Pending Transactions with BP p.l.c.  On January 11, 2003, we signed two
purchase and sales agreements with subsidiaries of BP p.l.c., which we refer to
collectively as "BP," to purchase their interests in 61 producing fields,
including 113 blocks in the Gulf of Mexico and two producing fields in the North
Sea. We will operate 36 of the producing fields in the Gulf of Mexico and both
of the producing fields in the North Sea.

     Each of the purchase agreements is effective as of January 1, 2003. We
anticipate the purchase of the Gulf of Mexico properties will close late in the
first quarter of 2003, and the purchase of the North Sea properties will close
late in the second quarter of 2003. The total purchase price for all of the
assets being acquired is $1.3 billion, with $670 million allocated to the
purchase of the Gulf of Mexico assets and $630 million allocated to the North
Sea assets. The actual price payable upon the closing of each purchase will be
reduced by the net cash flow attributable to the acquired fields, and increased
by interest on the purchase price, from January 1, 2003, until the date of
closing. The purchase price will also be subject to customary closing
adjustments. Owners of working interests in certain Gulf of Mexico properties
have preferential purchase rights which, if exercised, would reduce the
interests we purchase in those properties and the purchase price we would pay.
Neither acquisition is conditional upon the consummation of the other
acquisition.

     The properties we are acquiring from BP in the Gulf of Mexico complement
our extensive existing reserves and production in the Gulf, while the North Sea
properties establish a new core area for us. Of the Gulf of Mexico properties we
will acquire, most of the working interests exceed 50 percent, 19 of the fields
are owned 100 percent and approximately 70 percent of the production will be
operated by us. We are acquiring a 96 percent working interest in, and will be
the operator of, the North Sea properties.

     We estimate that the properties we will acquire in the BP transactions had
proved reserves as of January 1, 2003 of:

      --   186.5 MMbbls of crude oil and natural gas liquids; and

      --   279.9 Bcf of natural gas.

     Using the conventional equivalence of one barrel of oil to six Mcf of gas,
these estimated proved reserves totaled 233.2 MMboe and were approximately 80
percent oil and 20 percent gas. Approximately 93 percent of these estimated
proved reserves are developed reserves. We also estimate that 21 percent of the
total oil reserves and 100 percent of the reserves of natural gas are in the
Gulf of Mexico properties.

     The 2003 production estimates used to value the acquisition were:

      --   65.5 Mbbls per day of crude oil and natural gas liquids; and

      --   197.6 MMcf per day of natural gas.

                                       S-2


     The estimates mentioned in the preceding three paragraphs are based on our
analysis of historical production data, assumptions regarding capital
expenditures and anticipated production declines. The reserves and average daily
production attributable to the BP transactions are based solely on our internal
estimates and have not been reviewed by our independent reserve engineers. There
is no assurance that the BP transactions will be completed or, if completed,
that our estimates of reserves and average daily production will prove correct.

     In order to preserve our strong financial position in a period of
cyclically high gas and oil prices, we hedged 40.8 MMbbls of oil at an average
price of $24.78 per Bbl and 70 Bcf of natural gas at an average price of $4.55
per MMbtu through 2004. We have agreed to sell all of the North Sea production
from those properties over the next two years to BP at a combination of fixed
and market sensitive prices pursuant to a contract entered into in connection
with the North Sea purchase agreement. The fixed price portion of our contract
with BP is included in the 40.8 MMbbl oil hedge.

     The BP transactions have received all necessary corporate approvals, and
are not conditioned upon financing, but are subject to customary closing
conditions, regulatory approvals under the U.S. Hart-Scott-Rodino Act and, in
the case of the North Sea properties, U.K. regulatory and other approvals.

     Completed Acquisitions.  A significant part of our growth strategy is to
increase oil and gas reserves, production and cash flow through an active
acquisition program. Apache has consummated several acquisitions since January
1, 2002.

     In December 2002, Apache completed the acquisition of certain South
Louisiana properties comprising 234,000 net acres (366 square miles) with
estimated net proved reserves of 30 MMboe, 88 percent of which is estimated to
be natural gas, for approximately $260 million, subject to normal post-closing
adjustments. The acquisition also includes 135 producing wells and access to 849
square miles of 3-D seismic data covering the relatively contiguous acreage
position. Based on our analysis of historical production rates, assumptions
regarding capital expenditures and anticipated production declines, we
anticipate 2003 net daily production to approximate 55 MMcf of natural gas and
2,100 barrels of oil. We also entered into a separate exploration joint venture
with the seller whereby the seller will actively generate prospects on certain
South Louisiana acreage for a total cost of $25 million over a two year period.

     We have also completed several smaller acquisitions since January 1, 2002,
for an aggregate of approximately $95 million. Together, these acquisitions
include proved reserves of approximately 19 MMboe.

     2002 Drilling Results.  During 2002, we completed 1,018 gross wells as
producers out of a total of 1,089 gross wells drilled. In the fourth quarter of
2002, we announced our fourth deep water discovery on our West Mediterranean
concession offshore Egypt, and a new discovery in our Ras El Hekma concession in
Egypt. These wells were, respectively, the 10th and 11th discoveries for us in
Egypt and our 15th and 16th discoveries worldwide for the year.

                                  THE OFFERING

Common stock offered..........   8,200,000 shares

Common stock to be outstanding
after this offering...........   152,250,678 shares

Use of proceeds...............   We expect that our net proceeds from the
                                 offering will be approximately $481.2 million,
                                 after deducting underwriting discounts and
                                 commissions and estimated expenses of the
                                 offering payable by us. We intend to use the
                                 net proceeds from the offering, together with
                                 cash on hand, net cash generated from
                                 operations and short-term and long-term
                                 borrowings, to fund the cash requirements of
                                 the pending BP transactions. Pending such use,
                                 we will use the net proceeds to repay
                                 indebtedness under our commercial paper
                                 facilities and our money market lines of credit
                                 in the ordinary course of business or to make
                                 short-term investments. We will use any net
                                 proceeds not used to finance the BP
                                 transactions for general corporate purposes.

Dividends.....................   On December 18, 2002, we announced that our
                                 board of directors had declared a special 5
                                 percent dividend, payable in shares of our
                                 common stock, which will be paid on April 2,
                                 2003, to shareholders of record on March 12,
                                 2003. The board also declared the regular cash
                                 dividend on our common stock of $.10 per share.
                                 The cash dividend will be paid on February 21,
                                 2003, to shareholders of record on January 22,
                                 2003. Purchasers of our common stock in this

                      SUMMARY HISTORICAL FINANCIAL AND OPERATING DATA

     We have provided in the tables below our selected financial and operating
data. The financial information for each of the years in the three-year period
ended December 31, 2001, and at December 31, 1999, 2000 and 2001, has been
derived from our audited financial statements. The financial information for the
nine-month periods ended September 30, 2001 and 2002, and at September 30, 2001
and 2002, has been derived from our unaudited financial statements. In our
management's opinion, these unaudited financial statements have been prepared on
the same basis as our audited financial statements except as noted below. You
should read the following financial information in conjunction with our
consolidated financial statements and related notes that we have incorporated by
reference in the accompanying prospectus.

(1) Includes the results of the acquisitions of certain oil and gas properties
    from Petsec Energy Inc., Shell Offshore Inc. and affiliated Shell entities,
    British-Borneo Oil & Gas Plc and Shell Canada Limited after February 1,
    1999, May 18, 1999, June 18, 1999 and November 30, 1999, respectively.

(2) Includes the results of the acquisitions of certain oil and gas properties
    from Repsol, Collins & Ware, Occidental and Phillips after January 24, 2000,
    June 30, 2000, August 17, 2000, and December 29, 2000, respectively.

(3) Includes the results of the acquisitions of certain oil and gas properties
    from Repsol YPF and Fletcher Challenge Energy after March 22, 2001, and
    March 27, 2001, respectively.

(4) As a result of the consensus on Emerging Issues Task Force Issue 00-10,
    "Accounting for Shipping and Handling Fees and Costs," for the nine months
    ended September 30, 2002, third party gathering and transportation costs in
    the amount of $27.5 million have been reported as an operating expense
    instead of a reduction to revenues as previously reported. A
    reclassification has been made to reflect this change for the nine months
    ended September 30, 2001, resulting in an increase in reported revenue and
    operating expense for that period of $24.1 million. The change has no impact
    on income attributable to common stock. The income statement data for each
    of the years in the three-year period ended December 31, 2001, do not
    reflect the reclassification and report third party gathering and
    transportation costs as a reduction of revenues. For 1999, 2000 and 2001,
    the reclassification would result in an increase in reported revenue and
    operating expense of $15.1 million, $18.1 million and $32.3 million,
    respectively, with no impact on income attributable to common stock.

                                  RISK FACTORS

     Before making an investment in shares of our common stock, you should
carefully consider the risks described below, as well as the information
included or incorporated by reference in this prospectus supplement and the
accompanying prospectus. In addition, please read "Special Note Regarding
Forward-Looking Statements" in this prospectus supplement, where we describe
additional uncertainties associated with our business and the forward-looking
statements included or incorporated by reference in this prospectus supplement
and the accompanying prospectus.

REPERCUSSIONS FROM THE TERRORIST ACTS COMMITTED IN THE UNITED STATES COULD HARM
OUR BUSINESS OPERATIONS AND ADVERSELY IMPACT OUR ABILITY TO MEET OUR
EXPECTATIONS AND TO FULFILL OTHER FORWARD-LOOKING STATEMENTS CONTAINED IN THIS
PROSPECTUS SUPPLEMENT AND THE ACCOMPANYING PROSPECTUS.

     The terrorist attacks on September 11, 2001, have caused instability in the
world's markets. There can be no assurance that the current armed hostilities
will not escalate or that these terrorist attacks, or the United States'
responses to them, will not lead to further acts of terrorism and civil
disturbances in the United States or elsewhere, which may further contribute to
the economic instability in the United States and the other regions in which we
operate. Armed conflict, civil unrest, additional terrorist activities and the
attendant political instability and societal disruption may reduce demand for
our products or disrupt our ability to conduct our exploration, production,
development and marketing activities, which could harm our business.

OIL AND NATURAL GAS PRICES ARE VOLATILE. VOLATILITY IN OIL AND NATURAL GAS
PRICES CAN ADVERSELY AFFECT OUR RESULTS AND THE PRICE OF OUR COMMON STOCK. THIS
VOLATILITY ALSO MAKES VALUATION OF OIL AND GAS PRODUCING PROPERTIES DIFFICULT
AND CAN DISRUPT MARKETS.

     Oil and natural gas prices have historically been, and are likely to
continue to be, volatile. The prices for oil and natural gas are subject to wide
fluctuation in response to relatively minor changes in the supply of and demand
for oil and natural gas, market uncertainty, worldwide economic conditions,
weather conditions, import prices, political conditions in major oil producing
regions, especially the Middle East, and actions taken by OPEC. The prices for
oil and natural gas could be significantly affected by the prospect and outcome
of war in Iraq, for example.

     Our quarterly results of operations may fluctuate significantly as a result
of variations in oil and natural gas prices and production performance. In
recent years, oil and natural gas price volatility has become increasingly
severe. You can expect the market price of our common stock to decline when our
quarterly results decline or at any time when events actually or potentially
adverse to us or the industry occur. Our common stock price may decline to a
price below the price you paid to purchase your shares of common stock in this
offering.

     This volatility makes it difficult to estimate with precision the value of
producing properties in acquisitions and to budget and project the return on
exploration and development projects involving our oil and gas properties. In
addition, unusually volatile prices often disrupt the market for oil and gas
properties, as buyers and sellers have more difficulty agreeing on the purchase
price of properties.

A SUBSTANTIAL OR EXTENDED DECLINE IN OIL AND GAS PRICES WOULD HAVE A MATERIAL
ADVERSE EFFECT ON US.

     A substantial or extended decline in oil and gas prices would have a
material adverse effect on our financial position, results of operations,
quantities of oil and gas that may be economically produced, and access to
capital. A significant decrease in price levels for an extended period would
negatively affect us in several ways:

      --   our cash flow would be reduced, decreasing funds available for
           capital expenditures employed to replace reserves or increase
           production;

      --   certain reserves would no longer be economic to produce, leading to
           both lower proved reserves and cash flow; and

                                       S-7


      --   access to other sources of capital, such as equity or long-term debt
           markets, could be severely limited or unavailable.

Consequently, our revenues and profitability would suffer.

OUR ABILITY TO SELL OUR OIL AND GAS PRODUCTION COULD BE MATERIALLY HARMED IF WE
FAIL TO OBTAIN ADEQUATE SERVICES SUCH AS TRANSPORTATION AND PROCESSING.

     The sale of our oil and gas production, particularly outside of North
America, depends on a number of factors beyond our control, including the
availability and capacity of transportation and processing facilities. Our
failure to obtain such services on acceptable terms could materially harm our
business.

WE HAVE RECORDED WRITE-DOWNS BECAUSE OF FULL COST ACCOUNTING RULES AND MAY BE
REQUIRED TO DO SO AGAIN IN THE FUTURE.

     Under the full cost accounting rules of the U.S. Securities and Exchange
Commission ("SEC"), we review the carrying value of our proved oil and gas
properties each quarter on a country-by-country basis. Under these rules,
capitalized costs of proved oil and gas properties--net of accumulated
depreciation, depletion and amortization, and deferred income taxes--may not
exceed the present value of estimated future net cash flows from proved oil and
gas reserves, discounted at 10 percent, plus the lower of cost or fair value of
unproved properties included in the costs being amortized, net of related tax
effects.

     These rules generally require pricing future oil and gas production at the
unescalated oil and gas prices in effect at the end of each fiscal quarter. They
also require a write-down if the "ceiling" is exceeded, even if prices declined
for only a short period of time.

     If oil and gas prices fall significantly, a write-down may occur.
Write-downs required by these rules do not impact cash flow from operating
activities.

THE OIL AND GAS RESERVES DATA WE REPORT ARE ONLY ESTIMATES AND MAY PROVE TO BE
INACCURATE.

     There are numerous uncertainties inherent in estimating quantities of oil
and natural gas reserves of any category and in projecting future rates of
production and timing of development expenditures, which underlie the reserve
estimates, including many factors beyond our control. Reserve data represent
only estimates. In addition, the estimates of future net cash flows from our
proved reserves and their present value are based upon various assumptions about
future production levels, prices and costs that may prove to be incorrect over
time. Any significant variance from the assumptions could result in the actual
quantity of our reserves and future net cash flows from them being materially
different from the estimates. In addition, our estimated reserves may be subject
to downward or upward revision based upon production history, results of future
exploration and development, prevailing oil and gas prices, operating and
development costs and other factors.

     At December 31, 2001, approximately 24 percent of our estimated proved
reserves were undeveloped. Recovery of undeveloped reserves generally requires
significant capital expenditures and successful drilling operations. The reserve
data assumes that we can and will make these expenditures and conduct these
operations successfully, which may not occur.

IF WE FAIL TO ACQUIRE OR FIND ADDITIONAL RESERVES, OUR RESERVES AND PRODUCTION
WILL DECLINE MATERIALLY FROM THEIR CURRENT LEVELS.

     The rate of production from oil and gas properties generally declines as
reserves are depleted. Except to the extent that we acquire additional
properties containing proved reserves, conduct successful exploration and
development activities, successfully apply new technologies or, through
engineering studies, identify additional behind-pipe zones or secondary recovery
reserves, our proved reserves will decline materially as reserves are produced.
Future oil and gas production is, therefore, highly dependent upon our level of
success in acquiring or finding additional reserves.

                                       S-8


WE INCUR SUBSTANTIAL COSTS TO COMPLY WITH GOVERNMENT REGULATIONS, ESPECIALLY
REGULATIONS RELATING TO ENVIRONMENTAL PROTECTION, AND COULD INCUR EVEN GREATER
COSTS IN THE FUTURE.

     Our exploration, production, development and marketing operations are
regulated extensively at the federal, state and local levels, as well as by
other countries in which we do business. We have made and will continue to make
large expenditures in our efforts to comply with the requirements of
environmental and other regulations. Further, the oil and gas regulatory
environment could change in ways that might substantially increase these costs.

     Hydrocarbon-producing states regulate conservation practices and the
protection of correlative rights. These regulations affect our operations and
limit the quantity of hydrocarbons we may produce and sell. In addition, at the
U.S. federal level, the Federal Energy Regulatory Commission regulates
interstate transportation of natural gas under the Natural Gas Act. Other
regulated matters include marketing, pricing, transportation and valuation of
royalty payments.

     As an owner or lessee and operator of oil and gas properties, we are
subject to various federal, state, local and foreign regulations relating to
discharge of materials into, and protection of, the environment. These
regulations may, among other things, impose liability on us for the cost of
pollution clean-up resulting from operations, subject us to liability for
pollution damages, and require suspension or cessation of operations in affected
areas. Changes in or additions to regulations regarding the protection of the
environment could hurt our business.

     One of the responsibilities of owning and operating oil and gas properties
is paying for the cost of abandonment. Upon closing of our acquisition of the
North Sea properties, we have agreed to assume BP's abandonment obligation for
those properties, the cost of which we took into consideration in determining
the purchase price. Effective January 1, 2003, exploration and production
companies are required to reflect abandonment costs as a liability on their
balance sheets.

     Our purchase of the North Sea properties does not relieve BP of its
liabilities if we do not satisfy our abandonment obligation. To ensure our
payment of those costs, we have agreed to deliver a letter of credit to BP if
the rating of our senior unsecured debt is lowered by both Moody's and Standard
& Poor's. Any such letter of credit would be in an amount equal to the net
present value of future abandonment costs of the North Sea properties as of the
date of any such ratings change. If we are obligated to provide a letter of
credit, it will expire if either rating agency restores its rating to the
present level.

OUR BUSINESS COULD BE HARMED BY COMPETITION WITH OTHER COMPANIES.

     The oil and gas industry is highly competitive, and our business could be
harmed by competition with other companies. Because oil and gas are fungible
commodities, our principal form of competition is price competition. We strive
to maintain the lowest finding and production costs possible to maximize
profits. In addition, as an independent oil and gas company, we frequently
compete for reserve acquisitions, exploration leases, licenses, concessions and
marketing agreements against companies with financial and other resources
substantially larger than we possess. Many of our competitors have established
strategic long-term positions and maintain strong governmental relationships in
countries in which we may seek new entry.

WE DO NOT INSURE AGAINST ALL POTENTIAL LOSSES AND COULD BE SERIOUSLY HARMED BY
UNEXPECTED LIABILITIES.

     Exploration for and production of oil and natural gas can be hazardous,
involving natural disasters and other unforeseen occurrences such as blowouts,
cratering, fires and loss of well control, which can damage or destroy wells or
production facilities, injure or kill people, and damage property and the
environment. We maintain insurance against many potential losses or liabilities
arising from our operations in accordance with customary industry practices and
in amounts that we believe to be prudent. However, our insurance does not
protect us against all operational risks.

                                       S-9


OUR HEDGING ACTIVITIES MAY PREVENT US FROM BENEFITING FROM PRICE INCREASES AND
MAY EXPOSE US TO OTHER RISKS.

     To the extent that we engage in hedging activities, we may be prevented
from realizing the benefits of price increases above the levels of the hedges.
In addition, we are subject to risks associated with differences in prices at
different locations, particularly where transportation constraints restrict our
ability to deliver oil and gas volumes to the delivery point to which the
hedging transaction is indexed.

THE PENDING BP TRANSACTIONS MIGHT NOT BE CONSUMMATED AS EXPECTED.

     The BP transactions have received all necessary corporate approvals and are
not conditioned upon financing, but are subject to customary closing conditions,
regulatory approvals under the U.S. Hart-Scott-Rodino Act and, in the case of
the North Sea properties, U.K. regulatory and other approvals. We expect to
satisfy those remaining conditions. Owners of other working interests in certain
of the Gulf of Mexico properties have preferential rights to purchase portions
of the interests we expect to acquire from BP that, if exercised, would reduce
the interests we purchase in those fields and the purchase price we would pay.

     While we expect that the BP transactions will be closed and funded, we
cannot be sure that the transactions will be completed.

WHEN WE ACQUIRE OIL AND GAS PROPERTIES, SUCH AS THOSE FROM BP, OUR FAILURE TO
FULLY IDENTIFY AND CORRECTLY EVALUATE POTENTIAL PROBLEMS, TO PROPERLY ESTIMATE
RESERVES OR PRODUCTION RATES OR COSTS, OR TO EFFECTIVELY INTEGRATE THE ACQUIRED
OPERATIONS COULD SERIOUSLY HARM US.

     We are actively engaged in acquiring oil and gas properties. When we
acquire properties, such as those from BP, our failure to fully identify
potential problems, to properly estimate reserves or production rates or costs,
or to effectively integrate the acquired operations could seriously harm us.

     Although we perform reviews of acquired properties and applicable records
and contracts that we believe are consistent with industry practices, we do not
review in depth every individual property involved in each acquisition.
Ordinarily we focus on higher-value properties and sample the remainder.
However, even a detailed review of properties and applicable records and
contracts may not necessarily reveal existing or potential problems, nor will it
permit us to become sufficiently familiar with the properties to assess fully
their deficiencies and potential. Inspections may not always be performed on
every well, and environmental problems, such as ground water contamination, are
not necessarily observable even when an inspection is undertaken. Our review may
not sufficiently identify or evaluate applicable contracts under which third
parties may assert preferential rights to purchase some of the properties that
we believe we have acquired, rights to change or contest the operatorship of
acquired properties, or rights with respect to acquired properties under
agreements providing for areas of mutual interest. Even when we identify such
third party rights, we may not correctly evaluate their applicability or
potential consequences because of uncertain legal standards and for other
reasons.

     Even when problems are identified, we often assume environmental and other
risks and liabilities in connection with acquired properties. There are numerous
uncertainties inherent in estimating quantities of proved oil and gas reserves
and actual future production rates and associated costs with respect to acquired
properties. Actual results may vary substantially from those assumed in the
estimates. In addition, acquisitions may have adverse effects on our operating
results, particularly during the periods in which the operations of acquired
businesses are being integrated into our ongoing operations.

OUR NON-U.S. OPERATIONS, ESPECIALLY IN DEVELOPING COUNTRIES, ARE SUBJECT TO
INCREASED RISKS AND UNCERTAINTIES.

     Our non-U.S. oil and natural gas exploration, development and production
activities are subject to:

      --   political and economic uncertainties, including, among others,
           changes, sometimes frequent or marked, in governmental energy
           policies or the personnel administering them;

      --   expropriation of property;

                                       S-10


      --   cancellation or modification of contract rights;

      --   foreign exchange restrictions;

      --   currency fluctuations;

      --   risks of loss due to civil strife, acts of war, guerrilla activities
           and insurrection;

      --   royalty and tax increases; and

      --   other risks arising out of foreign governmental sovereignty over the
           areas in which our operations are conducted.

These risks may be higher in the developing countries in which we conduct these
activities. Consequently, our non-U.S. exploration, development and production
activities may be substantially affected by factors beyond our control, any of
which could materially adversely affect our financial position or results of
operations. Furthermore, in the event of a dispute arising from our non-U.S.
operations, we may be subject to the exclusive jurisdiction of courts outside
the United States or may not be successful in subjecting non-U.S. persons to the
jurisdiction of the courts in the United States, which could adversely affect
the outcome of the dispute.

A DECLINE IN THE CONDITION OF THE CAPITAL MARKETS OR A SUBSTANTIAL RISE IN
INTEREST RATES COULD HARM US.

     If the condition of the capital markets utilized by us to finance our
operations materially declines, we might not be able to finance our operations
on terms we consider acceptable. In addition, a substantial rise in interest
rates would decrease our net cash flows.

ADVERSE CHANGES IN THE EXCHANGE RATES WITH SOME FOREIGN CURRENCIES COULD HARM
US.

     Our cash flow stream relating to certain international operations is based
on the U.S. dollar equivalent of cash flows measured in foreign currencies.
Australian gas production is sold under fixed-price Australian dollar contracts
and over half the costs incurred are paid in Australian dollars. Revenue and
disbursement transactions denominated in Australian dollars are converted to
U.S. dollar equivalents based on the exchange rate on the transaction date.
Reported cash flow relating to Canadian operations is based on cash flows
measured in Canadian dollars converted to the U.S. dollar equivalent based on
the average of the Canadian and U.S. dollar exchange rates for the period
reported. Substantially all of our international transactions, outside of Canada
and Australia, are denominated in U.S. dollars.

     A decrease in value of 10 percent in the Canadian dollar, the Australian
dollar and Polish zloty relative to the U.S. dollar from the September 30, 2002
exchange rates would result in a foreign currency loss of approximately $16.0
million, based on September 30, 2002 amounts.

     The U.S. and Canadian energy markets continue to evolve into a single
energy market. In light of this continuing transformation, we adopted the U.S.
dollar as our functional currency in Canada, effective October 1, 2002. The U.S.
dollar is now the functional currency for all our foreign operations.

SUBSTANTIAL SALES OF OUR COMMON STOCK COULD CAUSE OUR STOCK PRICE TO DECLINE.

     If our existing stockholders sell a large number of shares of our common
stock or the public market perceives that existing stockholders might sell
shares of common stock, the market price of our common stock could significantly
decline. All of the shares offered by this prospectus supplement and the
accompanying prospectus will be freely tradable without restriction or further
registration under the federal securities laws unless purchased by an
"affiliate," as that term is defined in Rule 144 under the Securities Act of
1933. The outstanding shares subject to lock-up agreements between certain of
our directors and executive officers and the underwriters may be sold 90 days
after the effective date of this offering, except as noted in "Underwriting."

OUR STOCKHOLDER RIGHTS PLAN, CHARTER, BYLAWS, DELAWARE LAW AND OUR DEBT
SECURITIES DISCOURAGE UNSOLICITED TAKEOVER PROPOSALS AND COULD PREVENT YOU FROM
REALIZING A PREMIUM FOR YOUR COMMON STOCK.

     We have a stockholder rights plan that may have the effect of discouraging
unsolicited takeover proposals. The rights issued under the stockholder rights
plan would cause substantial dilution to a person or group that attempts to
acquire us on terms not approved in advance by our board of directors. In
addition, our charter, bylaws, Delaware law and our debt securities contain
provisions that may discourage unsolicited takeover proposals that stockholders
may consider to be in their best interests. The stockholder rights plan and
these provisions are described in "Description of Capital Stock--Stockholder
Rights Plan" beginning on page 11 of the accompanying prospectus dated March 30,
2000, and beginning on page 6 of the accompanying prospectus dated April 9,
1999, and in "--Anti-Takeover Effect of Provisions of Apache's Charter and
Bylaws and Delaware Law" beginning on page 13 of the accompanying prospectus
dated March 30, 2000, and beginning on page 7 of the accompanying prospectus
dated April 9, 1999. Our obligation to purchase our debt securities upon a
change in control is described in "Description of Debt Securities--We Are
Obligated to Purchase Debt Securities Upon a Change in Control" beginning on
page 27 of the accompanying prospectus dated March 30, 2000, and beginning on
page 20 of the accompanying prospectus dated April 9, 1999.

     Together these provisions and the stockholder rights plan may discourage
transactions that otherwise could involve payment of a premium over prevailing
market prices for your common stock.

INVESTORS IN OUR SECURITIES MAY ENCOUNTER DIFFICULTIES IN OBTAINING, OR MAY BE
UNABLE TO OBTAIN, RECOVERIES FROM ARTHUR ANDERSEN WITH RESPECT TO ITS AUDITS OF
OUR FINANCIAL STATEMENTS.

     On March 14, 2002, our previous independent public accountant, Arthur
Andersen LLP, was indicted on federal obstruction of justice charges arising
from the federal government's investigation of Enron Corp. On June 15, 2002, a
jury returned with a guilty verdict against Arthur Andersen following a trial.
As a public company, we are required to file with the SEC periodic financial
statements audited or reviewed by an independent public accountant. On March 29,
2002, we decided not to engage Arthur Andersen as our independent auditors, and
engaged Ernst & Young LLP to serve as our new independent auditors for 2002.
However, we are incorporating in this prospectus supplement and the accompanying
prospectus financial statements for 2001, 2000 and 1999 that were audited by
Arthur Andersen. Investors in our securities may encounter difficulties in
obtaining, or be unable to obtain, from Arthur Andersen with respect to its
audits of our financial statements relief that may be available to investors
under the federal securities laws against auditing firms.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus supplement, the accompanying prospectus, and the documents
incorporated herein and therein by reference contain statements that constitute
"forward looking statements" within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All
statements other than statements of historical facts, including, without
limitation, those relating to our future financial position, business strategy,
budgets, reserve information, projected levels of production, projected costs
and plans and objectives of management for future operations, are
forward-looking statements.

     Words such as "expect," "anticipate," "estimate," "intend," "plan,"
"believe" and similar expressions are intended to identify forward-looking
statements.

     Although we believe our expectations reflected in forward-looking
statements are based on reasonable assumptions, no assurance can be given that
these expectations will prove to have been correct. Important factors that could
cause actual results to differ materially from the expectations reflected in the
forward-looking statements include, among others:

      --   the market prices of oil and gas;

      --   uncertainty of drilling results, reserve estimates and reserve
           replacement;

      --   operating uncertainties and hazards;

                                       S-12


      --   economic and competitive conditions;

      --   natural disasters and other changes in business conditions;

      --   inflation rates;

      --   legislative and regulatory changes;

      --   financial market conditions;

      --   accuracy, completeness and veracity of information received from BP;

      --   wars and acts of terrorism or sabotage;

      --   political and economic uncertainties of foreign governments; and

      --   future business decisions.

Additional factors are discussed under "Risk Factors" beginning on page S-7 of
this prospectus supplement.

     In light of these risks, uncertainties and assumptions, the events
anticipated by our forward-looking statements might not occur. We undertake no
obligation to update or revise our forward-looking statements, whether as a
result of new information, future events or otherwise.

                                USE OF PROCEEDS

     We estimate the net proceeds from the offering of common stock to be
approximately $481.2 million, or $553.4 million if the underwriters'
over-allotment option is exercised in full, after deducting underwriting
discounts and commissions and estimated expenses of the offering payable by us.

     We intend to use the net proceeds from the offering, together with cash on
hand, net cash generated from operations and short-term and long-term
borrowings, to fund the cash requirements of the pending BP transactions.
Pending such use, we will use the net proceeds of the offering to repay
indebtedness under our commercial paper facilities and our money market lines of
credit in the ordinary course of our business or to make short-term investments.
The amount of repayment of indebtedness will depend, in part, on the closing of
the BP transactions. We will use any net proceeds not used to finance the BP
transactions for general corporate purposes. As of December 31, 2002, we had
$271.4 million face amount of commercial paper discounted at an average weighted
rate of 1.35 percent per annum and $8.9 million principal amount outstanding
under our money market lines of credit bearing interest at a variable rate,
currently 2.25 percent per annum.

                                       S-13


                                 CAPITALIZATION

     The following table sets forth, as of September 30, 2002, our cash and cash
equivalents and capitalization on:

      --   an actual basis; and

      --   an as adjusted basis giving effect to our receipt of the estimated
           net proceeds from the sale of the shares we are selling in the
           offering and the application of the net proceeds pending the closing
           of the BP transactions.

     The as adjusted cash and cash equivalents and capitalization amounts assume
that the over-allotment option is not exercised. The as adjusted amounts do not
reflect the effects of our acquisitions in the fourth quarter of 2002, which are
not material to our capitalization, or the financing of the pending BP
transactions. The table should be read in conjunction with our consolidated
financial statements and related notes incorporated by reference in this
prospectus supplement and the accompanying prospectus.

     On January 16, 2003, the last reported sale price for our common stock on
the New York Stock Exchange was $62.03 per share. Stockholders should obtain
current market quotations before making any decision with respect to an
investment in our common stock.

     At December 31, 2002, there were 144,050,678 shares of our common stock
outstanding, held by approximately 9,000 shareholders of record.

     Prices shown and shares outstanding exclude the shares issuable as a result
of the 5 percent stock dividend declared on December 18, 2002.

                                DIVIDEND POLICY

     We have paid cash dividends on our common stock for 36 consecutive years
through December 31, 2002. We increased the annual stock dividend to $.40 per
share in 2002. On December 18, 2002, we declared a special 5 percent common
stock dividend to be paid on April 2, 2003, to stockholders of record on March
12, 2003. We also declared a cash dividend on our common stock of $.10 per share
to be paid on February 21, 2003, to stockholders of record on January 22, 2003.
Although we expect to continue the payment of dividends at that level, future
dividend payments will depend upon our level of earnings, financial requirements
and other relevant factors.

     In December 1995, we declared a dividend of one preferred stock purchase
right for each share of our common stock outstanding on January 31, 1996 or
issued after that date. These rights are more fully described beginning on page
11 of the accompanying prospectus dated March 30, 2000, and beginning on page 6
of the accompanying prospectus dated April 9, 1999.

                     MATERIAL U.S. FEDERAL TAX CONSEQUENCES
                      TO NON-U.S. HOLDERS OF COMMON STOCK

     The following is a summary of material U.S. federal income and estate tax
consequences expected to result under current law from the purchase, ownership
and taxable disposition of common stock by non-U.S. holders of common stock. A
"non-U.S. holder" is any person or entity other than one who is for U.S. federal
income tax purposes:

      --   a citizen or resident of the United States;

      --   a corporation, partnership or other entity created or organized in or
           under the laws of the United States or any state thereof;

      --   an estate, the income of which is includable in gross income for U.S.
           federal income tax purposes regardless of its source; or

      --   a trust whose administration is subject to the primary supervision of
           a U.S. court and which has one or more U.S. persons who have the
           authority to control all substantial decisions of the trust.

     This summary does not address all of the U.S. federal income and estate tax
considerations that may be relevant to non-U.S. holders in light of their
particular circumstances, such as a valid election to be treated as a U.S.
person, or to non-U.S. holders that may be subject to special treatment under
U.S. federal income tax laws. This summary does not discuss any aspect of state,
local or foreign taxation. This summary is based on current provisions of the
Internal Revenue Code of 1986, as amended, Treasury regulations, judicial
opinions, published positions of the Internal Revenue Service and other
applicable authorities, all of which are subject to change, possibly with
retroactive effect. In this prospectus supplement, the Internal Revenue Code of
1986, as amended, is called the "Code." Prospective purchasers of common stock
are advised to consult their tax advisors regarding the U.S. federal, state and
local, and non-U.S. income and other tax consequences of acquiring, holding and
disposing of common stock.

DIVIDENDS

     Apache pays cash dividends on its common stock. Any dividends paid to a
non-U.S. holder on shares of common stock will be subject to withholding of U.S.
federal income tax at a rate of 30 percent, unless a lower rate is prescribed
under an applicable tax treaty. U.S. federal income tax withholding will not be
required, however, if the dividends are effectively connected with the conduct
of a trade or business of the non-U.S. holder within the United States or, in
the case of an applicable tax treaty, are attributable to a U.S. permanent
establishment maintained by the non-U.S. holder. Dividends that are effectively
connected with the conduct of a trade or business within the United States, or
are attributable to a U.S. permanent establishment will be subject to U.S.
federal income tax on a net income basis which is not collected by withholding
provided the non-U.S. holder files the appropriate certification with Apache or
its agent. Any dividends received by a foreign corporation that are effectively
connected with the conduct of a trade or business within the United States may
also be subject to a "branch profits tax" at a rate of 30 percent or such lower
rate as may be specified by an applicable tax treaty.

     For purposes of the withholding tax rules discussed above and for purposes
of determining the applicability of a tax treaty rate under current Treasury
Regulations, dividends paid to an address outside the United States will be
presumed to be paid to a resident of the country of address, unless the payor
has knowledge to the contrary. Under Treasury Regulations (referred to as "final
regulations") that are effective for payments made after December 31, 2000, a
non-U.S. holder of common stock who wishes to claim the benefit of a tax treaty
rate is required to satisfy applicable certification and other requirements. In
addition, under the final regulations, in the case of common stock held by a
foreign partnership:

      --   the certification requirement is generally applied to the partners of
           the partnership; and

      --   the partnership is required to provide certain information, including
           a U.S. taxpayer identification number.

                                       S-16


     A non-U.S. holder of common stock that is eligible for a reduced rate of
U.S. federal income tax withholding pursuant to a tax treaty may obtain a refund
of any excess amounts currently withheld by filing an appropriate claim for
refund with the Internal Revenue Service.

SALE OR DISPOSITION OF COMMON STOCK

     A non-U.S. holder generally will not be subject to U.S. federal income tax
in respect of any gain recognized on the sale or other taxable disposition of
common stock so long as:

      --   the gain is not effectively connected with the conduct of a trade or
           business of the non-U.S. holder within the United States and, under
           an applicable tax treaty, is not attributable to a U.S. permanent
           establishment maintained by the non-U.S. holder;

      --   in the case of a non-U.S. holder who is an individual and holds the
           common stock as a capital asset, either:

        --   such holder is not present in the United States for 183 or more
             days during the taxable year of the disposition; or

        --   such holder does not have a "tax home" in the United States for
             U.S. federal income tax purposes and such holder does not maintain
             an office or other fixed place of business in the United States to
             which such gain is attributable;

      --   such non-U.S. holder is not subject to tax pursuant to the provisions
           of U.S. federal income tax law applicable to certain U.S.
           expatriates; and

      --   the common stock continues to be "regularly traded on an established
           securities market" for U.S. federal income tax purposes and the
           non-U.S. holder has not held, directly or indirectly, at any time
           during the five-year period ending on the date of disposition (or, if
           shorter, the non-U.S. holder's holding period) more than five percent
           of the outstanding common stock.

INFORMATION REPORTING AND BACKUP WITHHOLDING

     Apache must report annually to the Internal Revenue Service and to each
non-U.S. holder the amount of dividends paid to, and the tax withheld with
respect to, each non-U.S. holder. These reporting requirements apply regardless
of whether withholding was reduced by an applicable tax treaty. Copies of these
information returns may also be made available under the provisions of a treaty
or information exchange agreement with the tax authorities in the country in
which the non-U.S. holder resides or is established. Under current law, U.S.
backup withholding tax, which is a withholding tax at the applicable statutory
rate on certain payments to persons who fail to furnish the information required
under U.S. information reporting requirements, generally will not apply to
dividends paid on common stock to a non-U.S. holder at an address outside the
United States unless the payor has knowledge that the payee is a U.S. person.
However, under the final regulations, dividends paid on common stock after
December 31, 2000, may be subject to backup withholding unless applicable
certification requirements are satisfied.

     Payment of the proceeds from a sale of common stock to or through a U.S.
office of a broker will be subject to information reporting and backup
withholding unless the owner certifies as to its status as a non-U.S. holder
under penalties of perjury or otherwise establishes an exemption. Payment of the
proceeds from a sale of common stock to or through a non-U.S. office of a broker
generally will not be subject to information reporting or backup withholding.
However, if such broker is a U.S. person, a "controlled foreign corporation" or
a foreign person that derives 50 percent or more of its gross income from the
conduct of a trade or business in the United States, such payment will be
subject to information reporting, but currently not backup withholding, unless
such broker has documentary evidence in its records that the owner is a non-U.S.
holder and certain other conditions are met or the owner otherwise establishes
an exemption.

     Any amounts withheld under the backup withholding rules will be credited
against the non-U.S. holder's federal income tax liability, if any, or refunded,
provided the required information is furnished to the Internal Revenue Service.
                                       S-17


ESTATE TAX

     The fair market value of common stock owned, or treated as owned, by an
individual at the time of his death will be includable in his gross estate for
U.S. federal estate tax purposes and thus may be subject to U.S. federal estate
tax, even though the individual at the time of death is neither a citizen of nor
domiciled in the United States, unless an applicable estate tax treaty provides
otherwise.

GROWTH AND JOBS PLAN PROPOSED BY PRESIDENT BUSH ON JANUARY 7, 2003

     President George W. Bush recently proposed a new tax plan that, if enacted,
would eliminate U.S. federal income tax on certain dividends paid on common
stock by corporations that pay U.S. federal income tax. Under the proposal,
dividends would not be subject to U.S. federal income tax if (i) they are paid
from profits earned by corporations in 2002 or later, and (ii) the corporation
has paid U.S. federal income tax on such profits. As currently proposed,
President Bush's plan, if enacted, would require us, upon payment of dividends,
to inform shareholders of the amount of the dividend that would be "tax-free"
under the plan. The current proposal does not include sufficient detail to
permit us to determine what effect, if any, the proposal would have on the
withholding requirements applicable to non-U.S. persons who own shares of our
common stock. The proposal is preliminary in nature and must be reduced to
legislation that will be proposed in Congress. There can be no assurance that
the proposal will be enacted into law.

                                  UNDERWRITING

     Under the terms and subject to the conditions contained in an underwriting
agreement dated the date of this prospectus supplement, the underwriters named
below, for whom Morgan Stanley & Co. Incorporated is acting as the
representative, have severally agreed to purchase, and we have agreed to sell to
them, severally, the number of shares of our common stock indicated below:

     The underwriters are offering the shares of common stock subject to their
acceptance of the shares from us and subject to prior sale. The underwriting
agreement provides that the obligations of the several underwriters to pay for
and accept delivery of the shares of common stock offered by this prospectus
supplement are subject to the approval of certain legal matters by their counsel
and to certain other conditions. The underwriters are obligated to take and pay
for all of the shares of common stock offered by this prospectus supplement if
any such shares are purchased. However, the underwriters are not required to
take or pay for the shares covered by the underwriters' over-allotment option
described below.

     The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price listed on the cover
page of this prospectus supplement and part to certain dealers at a price that
represents a concession not in excess of $1.49 a share under the public offering
price. After the initial offering of the shares of our common stock, the
offering price and other selling terms may from time to time be varied by the
representatives.

     The following table shows public offering price, underwriting discount and
proceeds before expenses to Apache. This information assumes either no exercise
or full exercise by the underwriters of their over-allotment option.



                                                                    TOTAL

Proceeds, before expenses, to Apache......  $58.7125     $481,442,500    $553,658,875


     The expenses of this offering, not including the underwriting discount and
commissions, are estimated at $265,000 and are payable by Apache.

     We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus supplement, to purchase up to an aggregate of
1,230,000 additional shares of common stock at the public offering price listed
on the cover page of this prospectus supplement, less underwriting discounts and
commissions. The underwriters may exercise this option solely for the purpose of
covering over-allotments, if any, made in connection with the offering of the
shares of common stock hereby. To the extent the option is exercised, each
underwriter will become obligated, subject to certain conditions, to purchase
approximately the same percentage of the additional shares of common stock as
the number listed next to the underwriter's name in the next preceding table
bears to the total number of shares of common stock listed next to the name of
all underwriters in the next preceding table.

                                       S-19


     We and our directors and executive officers have agreed that, without the
prior written consent of Morgan Stanley & Co. Incorporated on behalf of the
underwriters, we, he or she will not, during the period ending 90 days after the
date of this prospectus supplement:

      --   offer, pledge, sell, contract to sell, sell any option or contract to
           purchase, purchase any option or contract to sell, grant any option,
           right or warrant to purchase, lend or otherwise transfer or dispose
           of, directly or indirectly, any shares of our common stock or any
           securities convertible into or exercisable or exchangeable for our
           common stock or file any registration statement under the Securities
           Act of 1933 with respect to the foregoing; or

      --   enter into any swap or other arrangement that transfers to another,
           in whole or in part, any of the economic consequences of ownership of
           the common stock;

whether any transaction described above is to be settled by delivery of common
stock or such other securities, in cash or otherwise. In addition, our directors
and executive officers have agreed that, without the prior consent of Morgan
Stanley & Co. Incorporated on behalf of the underwriters, they will not, during
the period ending 90 days after the date of this prospectus supplement, make any
demand for, or exercise any right with respect to, the registration of any
shares of our common stock or any securities convertible into or exercisable or
exchangeable for our common stock.

     The restrictions described in the preceding paragraph do not apply to:

      --   the sale of shares to the underwriters pursuant to the underwriting
           agreement;

      --   transactions by any person other than us relating to shares of our
           common stock or other securities acquired in open market transactions
           after the completion of this offering;

      --   any shares of common stock issued pursuant to our existing dividend
           reinvestment program;

      --   the grant of options or common stock under our stock and incentive
           plans as in effect at the date hereof or the issuance of shares of
           our common stock under our non-employee director stock plan or
           dividend reinvestment plan;

      --   the issuance by us of shares of our common stock upon the exercise of
           an option or a warrant or the conversion of a security outstanding on
           the date hereof and disclosed in this prospectus supplement and the
           accompanying prospectus; or

      --   the issuance by us of shares of our common stock in connection with a
           purchase of assets or other transaction described in this prospectus
           supplement and the accompanying prospectus.

     In addition, the restrictions on our directors and executive officers do
not apply to the sale of shares of common stock upon the exercise of options for
less than 9,000 shares of common stock held by one of our executive officers
under our stock and incentive plans, which options will expire within 90 days of
the date of this prospectus supplement, or any transfer or disposition of common
stock to Apache pursuant to a cashless exercise of an option to purchase common
stock granted pursuant to a benefit plan and existing as of the date of this
prospectus supplement.

     In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may sell more shares
than they are obligated to purchase under the underwriting agreement, creating a
short position. A short sale is covered if the short position is no greater than
the number of shares available for purchase by the underwriters under the
over-allotment option. The underwriters can close out a covered short sale by
exercising the over-allotment option or purchasing shares in the open market. In
determining the source of shares to close out a covered short sale, the
underwriters will consider, among other things, the open market price of shares
compared to the price available under the over-allotment option. The
underwriters may also sell shares in excess of the over-allotment option,
creating a naked short position. The underwriters must close out any naked short
position by purchasing shares in the open market. A naked short position is more
likely to be created if the underwriters are concerned that there may be
downward pressure on the price of the common stock in the open market after
pricing that could adversely affect investors who purchase in the offering. As
an
                                       S-20


additional means of facilitating the offering, the underwriters may bid for, and
purchase, shares of common stock in the open market to stabilize the price of
the common stock. The underwriting syndicate may also reclaim selling
concessions allowed to an underwriter or a dealer for distributing the common
stock in the offering, if the syndicate repurchases previously distributed
common stock to cover syndicate short positions or to stabilize the price of the
common stock. These activities may raise or maintain the market price of the
common stock above independent market levels or prevent or retard a decline in
the market price of the common stock. The underwriters are not required to
engage in these activities and may end any of these activities at any time.

     In the ordinary course of their business, certain of the underwriters and
their respective affiliates have provided, or may in the future provide,
investment banking and other financial services to us or our subsidiaries,
including underwriting, the provision of financial advice and the extension of
credit. These underwriters and their affiliates have received, and may in the
future receive, customary fees and commissions for their services. Morgan
Stanley has performed investment banking and other financial services for Apache
and has received compensation for these services, which included services to
Apache in connection with the BP transactions. Salomon Smith Barney Inc. acted
as co-arranger on the $1.5 billion global credit facility that we entered into
on June 3, 2002.

     We have agreed to indemnify the underwriters against a variety of
liabilities, including liabilities under the Securities Act of 1933.

                                 LEGAL MATTERS

     Chamberlain, Hrdlicka, White, Williams & Martin, Houston, Texas, our
outside legal counsel, and our Vice President and Associate General Counsel,
Eric L. Harry, or our Attorney and Assistant Secretary, Jeffrey B. King, will
issue opinions about some legal matters in connection with the offering. As of
December 31, 2002, Mr. Harry owned 5,060 shares of common stock through Apache's
401(k) savings plan, held 3,300 restricted shares of common stock (none of which
was vested), held employee stock options to purchase 11,826 shares of common
stock (of which options to purchase 9,020 shares were currently exercisable) and
held conditional grants covering 9,382 shares of common stock (none of which was
vested). As of December 31, 2002, Mr. King owned 102 shares of common stock
through Apache's 401(k) savings plan, held employee stock options to purchase
10,108 shares of common stock (of which options to purchase 4,082 shares were
currently exercisable) and held conditional grants covering 6,379 shares of
common stock (none of which was vested). Sidley Austin Brown & Wood LLP, New
York, New York, will issue an opinion about some legal matters in connection
with the offering for the underwriters.

                                    EXPERTS

     The audited consolidated financial statements of Apache Corporation
incorporated by reference in this prospectus supplement and the accompanying

may be unable to obtain, recoveries from Arthur Andersen with respect to its
audits of our financial statements."

important information to you by referring you to those documents. The
information incorporated by reference is an important part of this prospectus,
and information that we file later with the Securities and Exchange Commission
will automatically update and supersede this information. Until we sell all of
the securities covered by this prospectus, we incorporate by reference the
documents filed by us listed below and any future filings we make with the
Securities and Exchange Commission under Sections 13(a), 13(c), 14 or 15(d) of

     There are no separate financial statements of the Apache Trusts in this
prospectus. We do not believe these financial statements would be helpful
because:

     - the Apache Trusts are wholly-owned subsidiaries of Apache, which files
       consolidated financial information under the Securities Exchange Act;

     - the Apache Trusts will not have any independent operations other than
       issuing trust preferred securities and trust common securities,
       purchasing debt securities of Apache Corporation and other necessary or
       incidental activities as described in this prospectus; and

     - Apache guarantees the trust preferred securities of the Apache Trusts.

     Our web site address is http://www.apachecorp.com. The information on our
web site is not incorporated by reference into this prospectus. You should rely
only on the information incorporated by reference or provided in this prospectus
or any prospectus supplement. Neither Apache nor either Apache Trust has
authorized anyone to provide you with different information.

     Neither Apache nor either Apache Trust is making an offer of the securities

           CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus and the documents incorporated by reference in this
prospectus contain "forward-looking statements" within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. These statements are based on our current expectations, estimates and
projections. Therefore, they could ultimately prove to be inaccurate. Our plans
for capital and exploratory spending and for cost and expense reduction may
change if business conditions, such as energy prices and world economic
conditions, change. Other factors that may have a direct bearing on our results
of operations and financial condition are:

     - competitive practices in the industries in which we compete;

     - fluctuations in oil and gas prices that have not been properly hedged or
       that are inconsistent with our marketing activities;

     - operational and systems risks;

     - environmental liabilities that are not covered by indemnity or insurance;

     - general economic and capital market conditions, including fluctuations in
       interest rates; and

     - the impact of current and future laws and governmental regulations
       (particularly environmental regulations) affecting the energy industry in
       general and Apache's operations in particular.

                               APACHE CORPORATION

     Apache Corporation is a Delaware corporation formed in 1954. We are an
independent energy company that explores for, develops and produces natural gas,
crude oil and natural gas liquids. In North America, our exploration and
production interests are focused on the Gulf of Mexico, the Anadarko Basin, the
Permian Basin, the Gulf Coast and the Western Sedimentary Basin of Canada.
Outside of North America, we have exploration and production interests offshore
Western Australia and in Egypt and exploration interests in Poland and offshore
The People's Republic of China.

     We hold interests in many of our U.S., Canadian and international
properties through operating subsidiaries, such as Apache Canada Ltd., DEK
Energy Company, which was formerly known as DEKALB Energy Company, Apache Energy
Limited, which was formerly known as Hadson Energy Limited, Apache
International, Inc., and Apache Overseas, Inc. The properties referred to in
this prospectus, in any prospectus supplement or in any other document
incorporated by reference in this prospectus may be held by our subsidiaries. We
treat all operations as one line of business.

                                 APACHE TRUSTS

     We created Apache Trust I and Apache Trust II, each of which is a Delaware
business trust, pursuant to trust agreements and the filing of certificates of
trust with the Delaware Secretary of State. We will execute amended and restated
trust agreements for the Apache Trusts, referred to in this prospectus as the
"trust agreements," which will state the terms and conditions for the Apache
Trusts to issue and sell their trust preferred securities and trust common
securities. We have filed a form of trust agreement as an exhibit to the
registration statement of which this prospectus forms a part.

     The Apache Trusts will exist solely to:

     - issue and sell their trust preferred securities and trust common
       securities;

     - use the proceeds from the sale of their trust preferred securities and
       trust common securities to purchase Apache's debt securities; and

     - engage in other activities that are necessary or incidental to the above
       purposes.

     We will hold directly or indirectly all of the trust common securities of
each of the Apache Trusts. The trust common securities will represent an
aggregate liquidation amount equal to at least 3% of each Apache Trust's total
capitalization. The trust preferred securities will represent the remaining
percentage of

                                        3


each Apache Trust's total capitalization. The trust common securities will have
terms substantially identical to, and will rank equal in priority of payment
with, the trust preferred securities. However, if Apache defaults on the debt
securities owned by an Apache Trust or another event of default under the trust
agreement occurs, then, so long as the default continues, cash distributions and
liquidation, redemption and other amounts payable or deliverable on the
securities of that trust must be paid or delivered to the holders of the trust
preferred securities of that trust before the holders of the common securities
of that trust.

     The Apache Trusts may not borrow money, issue debt, execute mortgages or
pledge any of their assets.

     The trust preferred securities will be guaranteed by us as described in
this prospectus and the applicable prospectus supplement.

     Unless otherwise specified in the applicable prospectus supplement, the
following four trustees will conduct each Apache Trust's business and affairs:

     - The Chase Manhattan Bank, a New York banking corporation, as property
       trustee;

     - Chase Manhattan Bank Delaware, a Delaware banking corporation, as
       Delaware trustee; and

     - two of our officers, as administrative trustees.

     Only we, as direct or indirect owner of the trust common securities, can
remove or replace the administrative trustees. In addition, we can increase or
decrease the number of administrative trustees. Also, we, as direct or indirect
holder of the trust common securities, will generally have the sole right to
remove or replace the property and Delaware trustees. However, if Apache
defaults on the debt securities owned by an Apache Trust or another event of
default under the trust agreement occurs, then, so long as that default is
continuing, the holders of a majority in liquidation amount of the outstanding
trust preferred securities of that trust may remove and replace the property and
Delaware trustees for that trust.

     We will pay all fees and expenses related to the Apache Trusts and the
offering of the trust preferred securities. We will also pay all ongoing costs
and expenses of the Apache Trusts, except each trust's obligations under the
trust preferred securities and trust common securities.

                    RATIOS OF EARNINGS TO FIXED CHARGES AND
                           TO COMBINED FIXED CHARGES
                         AND PREFERRED STOCK DIVIDENDS

     Our ratios of earnings to fixed charges and our ratios of earnings to
combined fixed charges and preferred stock dividends were as follows for the
periods indicated in the table below.



                                                                  YEAR ENDED DECEMBER 31,
                                                              --------------------------------
                                                              1999   1998   1997   1996   1995
                                                              ----   ----   ----   ----   ----
                                                                           
Ratio of earnings to fixed charges..........................  3.03     --   2.93   2.72   1.15
Ratio of earnings to combined fixed charges and preferred
  stock dividends...........................................  2.58     --   2.93   2.72   1.15


     Our ratios of earnings to fixed charges and our ratios of earnings to
combined fixed charges and preferred stock dividends were computed based on:

     - "earnings," which consist of consolidated income or losses from
       continuing operations plus income taxes and fixed charges, except
       capitalized interest or, in the case of our ratios of earnings to
       combined fixed charges and preferred stock dividends, those earnings plus
       preferred stock dividends; and

                                        4


     - "fixed charges," which consist of consolidated interest on indebtedness,
       including capitalized interest, amortization of debt discount and
       expense, and the estimated portion of rental expense attributable to
       interest.

     Due to the $243.2 million non-cash write-down of the carrying value of our
U.S. proved oil and gas properties for the year ended December 31, 1998, our
1998 earnings were inadequate to cover fixed charges by $236.8 million and
inadequate to cover combined fixed charges and preferred stock dividends by
$239.7 million.

     On May 17, 1995, Apache acquired DEKALB Energy Company, which is now known
as DEK Energy Company, through a merger which resulted in DEKALB becoming a
wholly-owned subsidiary of Apache. The merger was accounted for as a "pooling of
interests." As a result, our financial information for all preceding periods was
restated.

                                USE OF PROCEEDS

     Unless otherwise indicated in an accompanying prospectus supplement, we
expect to use the net proceeds from the sale of our securities for general
corporate purposes, which may include, among other things:

     - the repayment of outstanding indebtedness;

     - working capital;

     - capital expenditures; and

     - acquisitions.

     The precise amount and timing of the application of such proceeds will
depend upon our funding requirements and the availability and cost of other
funds.

     The Apache Trusts will use all proceeds from the sale of the trust common
and trust preferred securities to purchase debt securities of Apache.

             THE SECURITIES APACHE AND THE APACHE TRUSTS MAY OFFER

     The descriptions of the securities contained in this prospectus, together
with the applicable prospectus supplements, summarize all the material terms and
provisions of the various types of securities that Apache and the Apache Trusts
may offer. The particular terms of the securities offered by any prospectus
supplement will be described in that prospectus supplement. If indicated in the
applicable prospectus supplement, the terms of the securities may differ from
the terms summarized below. The prospectus supplement will also contain
information, where applicable, about material U.S. federal income tax
considerations relating to the securities, and the securities exchange, if any,
on which the securities will be listed.

     We may sell from time to time, in one or more offerings:

     - common stock and related rights;

     - preferred stock;

     - depositary shares;

     - common stock purchase contracts;

     - common stock purchase units;

     - senior debt securities; and/or

     - subordinated debt securities

     The Apache Trusts may offer and sell from time to time their trust
preferred securities guaranteed by us.
                                        5


     In this prospectus, Apache and the Apache Trusts refer to the common stock
and related rights, preferred stock, depositary shares, common stock purchase
contracts, common stock purchase units, senior debt securities, subordinated
debt securities, trust preferred securities and our guarantees of the trust
preferred securities collectively as "securities."

     If Apache and/or the Apache Trusts issue securities at a discount from
their original stated principal or liquidation amount, then, for purposes of
calculating the total dollar amount of all securities issued under this
prospectus, Apache and/or the Apache Trusts will treat the initial offering
price of the securities as the total original principal or liquidation amount of
the securities.

     This prospectus may not be used to sell securities unless it is accompanied
by a prospectus supplement.

                          DESCRIPTION OF CAPITAL STOCK

     The following descriptions of our common stock and preferred stock,
together with the additional information included in any applicable prospectus
supplements, summarize the material terms and provisions of these types of
securities. For the complete terms of our common stock and preferred stock,
please refer to our charter, bylaws and stockholder rights plan that are
incorporated by reference into the registration statement that includes this
prospectus or may be incorporated by reference in this prospectus. The terms of
these securities may also be affected by the General Corporation Law of the
State of Delaware.

     Under our charter, our authorized capital stock consists of 215,000,000
shares of common stock, $1.25 par value per share, and 5,000,000 shares of
preferred stock, no par value. We will describe the specific terms of any common
stock or preferred stock we may offer in a prospectus supplement. If indicated
in a prospectus supplement, the terms of any common stock or preferred stock
offered under that prospectus supplement may differ from the terms described
below.

COMMON STOCK

     As of February 29, 2000, Apache had approximately 113,640,647 shares of
common stock issued and outstanding. Also as of February 29, 2000, subject to
stock dividends and other events, up to 5,737,900 shares of common stock were
issuable upon conversion of our Series C preferred stock, as described below
under "Preferred Stock -- Series C." Each outstanding share of common stock
currently has attached to it one preferred share purchase right issued under our
stockholder rights plan, which is summarized below. All outstanding shares of
common stock are, and any shares of common stock sold pursuant to this
prospectus will be, duly authorized, validly issued, fully paid and
nonassessable.

  Voting

     For all matters submitted to a vote of stockholders, each holder of common
stock is entitled to one vote for each share registered in his or her name on
the books of Apache. Our common stock does not have cumulative voting rights. As
a result, subject to the voting rights of Series B and Series C preferred
stockholders and any future holders of our preferred stock, persons who hold
more than 50% of the outstanding common stock entitled to elect members of the
board of directors can elect all of the directors who are up for election in a
particular year.

  Dividends

     If our board of directors declares a dividend, holders of common stock will
receive payments from the funds of Apache that are legally available to pay
dividends. However, this dividend right is subject to any preferential dividend
rights we have granted to Series B and Series C preferred stockholders or may
grant to future holders of preferred stock.

  Liquidation

     If Apache is dissolved, the holders of common stock will be entitled to
share ratably in all the assets that remain after we pay our liabilities and any
amounts we may owe to the persons who hold our preferred stock.

  Other Rights and Restrictions

     Holders of common stock do not have preemptive rights, and they have no
right to convert their common stock into any other securities. Our common stock
is not subject to redemption by Apache. Our charter and bylaws do not restrict
the ability of a holder of common stock to transfer his or her shares of common
stock.

     Delaware law provides that, if we make a distribution to our stockholders
other than a distribution of our capital stock either when we are insolvent or
when we would be rendered insolvent, then our
                                        7


stockholders would be required to pay back to us the amount of the distribution
we made to them, or the portion of the distribution that causes us to become
insolvent, as the case may be.

  Listing

     Our common stock is listed on the New York Stock Exchange and the Chicago
Stock Exchange under the symbol "APA."

  Transfer Agent and Registrar

     The transfer agent and registrar for our common stock is Norwest Bank
Minnesota, National Association.

PREFERRED STOCK

  General

     We have 5,000,000 shares of no par preferred stock authorized, of which
25,000 shares have been designated as Series A Junior Participating Preferred
Stock, 100,000 shares have been designated as 5.68% Series B Cumulative
Preferred Stock and 140,000 shares have been designated as Automatically
Convertible Equity Securities, Conversion Preferred Stock, Series C. The
remaining shares of preferred stock are undesignated.

     Our charter authorizes our board of directors to issue preferred stock in
one or more series and to determine the voting rights and dividend rights,
dividend rates, liquidation preferences, conversion rights, redemption rights,
including sinking fund provisions and redemption prices, and other terms and
rights of each series of preferred stock.

  Series A

     The shares of Series A preferred stock are authorized for issuance pursuant
to rights that trade with outstanding Apache common stock and are reserved for
issuance upon the exercise of the rights discussed below under the caption
"-- Stockholder Rights Plan."

  Series B

     As of February 29, 2000, Apache had issued and outstanding 100,000 shares
of Series B preferred stock in the form of one million depositary shares, each
representing one-tenth ( 1/10) of a share of Series B preferred stock. The
Series B preferred stock has no stated maturity, is not subject to a sinking
fund and is not convertible into Apache common stock or any other securities.
Apache has the option to redeem the Series B preferred stock at $1,000 per share
on or after August 25, 2008. Holders of the depositary shares are entitled to
receive cumulative cash dividends at an annual rate of $5.68 per depositary
share (based on $56.80 for each share of Series B preferred stock) when, as and
if declared by Apache's board of directors.

     The Series B preferred stock has a liquidation preference of $1,000 per
share, which is equivalent to $100 per depositary share, plus accrued and unpaid
dividends.

     The Series B preferred stock ranks prior and superior to our common stock
and Series A preferred stock as to payment of dividends and distribution of
assets upon our dissolution, liquidation or winding up.

     The Series B preferred stock ranks equal to the Series C preferred stock as
to payment of dividends and distribution of assets upon dissolution, liquidation
or winding up.

     If dividends are not paid on the Series B preferred stock, cash payments on
our common stock and any other capital stock of Apache that ranks junior to the
Series B preferred stock as to dividends are prohibited and payments on any
other capital stock of Apache that ranks equal to the Series B preferred stock
as to dividends, including the Series C preferred stock, are restricted.

                                        8


     Shares of Series B preferred stock generally do not have voting rights.
However, if we fail to pay the equivalent of six quarterly dividends payable on
the Series B preferred stock or another class or series of preferred stock that
ranks equally with the Series B preferred stock, including the Series C
preferred stock, then we will increase the size of our board of directors by two
members. The holders of the Series B preferred stock and any other class or
series of preferred stock ranking equally with the Series B preferred stock,
including the Series C preferred stock, voting as a single class together with
any other class of preferred stock ranking equally, will then have the right to
vote for the two additional directors. This voting right would continue until we
have paid all past dividends on all preferred stock.

     Without the vote of at least 80% of the outstanding shares of Series B
preferred stock, we may not amend any provision in our charter so as to
adversely affect the powers, preferences, privileges or rights of the Series B
preferred stock.

     Without the approval of the holders, voting together as a single class, of
80% of all the shares of Series B preferred stock then outstanding and all
shares of any other series of the preferred stock of Apache ranking equally as
to dividends or upon liquidation, including the Series C preferred stock, we
will not:

     - issue, authorize or increase the authorized amount of, or issue or
       authorize any obligation or security convertible into or evidencing a
       right to purchase, any stock of any class ranking prior to the Series B
       preferred stock as to dividends or upon liquidation; or

     - reclassify any authorized Apache stock into any stock of any class, or
       any obligation or security convertible into or evidencing a right to
       purchase such stock, ranking prior to the Series B preferred stock,

provided that no such vote will be required for Apache to take any of these
actions to issue, authorize or increase the authorized amount of, or issue or
authorize any obligation or security convertible into or evidencing a right to
purchase, any stock ranking equally with or junior to the Series B preferred
stock.

     Without the approval of the holders of at least a majority of the shares of
Series B preferred stock then outstanding, we will not become a party to any
merger, conversion, consolidation or compulsory share exchange unless the terms
of that transaction do not provide for a change in the terms of the Series B
preferred stock and the Series B preferred stock ranks equally with or prior to
any capital stock of the surviving corporation as to dividends or upon
liquidation, dissolution or winding up other than prior-ranking Apache stock
previously authorized with the consent of holders of the Series B preferred
stock.

  Series C

     As of February 29, 2000, Apache had issued and outstanding 138,482 shares
of Series C preferred stock in the form of 6,924,100 depositary shares, each
representing one-fiftieth ( 1/50) of a share of Series C preferred stock.
Holders of the shares are entitled to receive cumulative cash dividends at an
annual rate of $2.015 per depositary share (based on $100.75 for each share of
Series C preferred stock) when, as and if declared by Apache's board of
directors.

     On May 15, 2002, each depositary share will automatically convert into
shares of Apache common stock at an exchange rate that will be not more than one
share and not less than 0.8197 shares of Apache common stock per depositary
share. The exchange rate will depend on the current market value of Apache
common stock prior to the date of conversion, and is subject to adjustments for
stock dividends and other events.

     At any time prior to May 15, 2002, holders may elect to convert each
depositary share into 0.8197 of a share of Apache common stock, subject to
adjustments for stock dividends and other events.

     The Series C preferred stock has a liquidation preference of $1,550 per
share, which is equivalent to $31 per depositary share, plus accrued and unpaid
dividends.

     The Series C preferred stock ranks prior and superior to our common stock
and Series A preferred stock as to payment of dividends and distribution of
assets upon our dissolution, liquidation or winding up.

                                        9


     The Series C preferred stock ranks equal to the Series B preferred stock as
to payment of dividends and distribution of assets upon our dissolution,
liquidation or winding up.

     If dividends are not paid on the Series C preferred stock, cash payments on
our common stock and any other capital stock of Apache that ranks junior to the
Series C preferred stock as to dividends are prohibited and payments on any
other capital stock of Apache that ranks equal to the Series C preferred stock
as to dividends, including the Series B preferred stock, are restricted.

     Shares of Series C preferred stock generally do not have voting rights.
However, if we fail to pay the equivalent of six quarterly dividends payable on
the Series C preferred stock or another class or series of preferred stock that
ranks equally with the Series C preferred stock, including the Series B
preferred stock, then we will increase the size of our board of directors by two
members. The holders of the Series C preferred stock and any other class or
series of preferred stock ranking equally with the Series C preferred stock,
including the Series B preferred stock, voting as a single class together with
any other class of preferred stock ranking equally, will then have the right to
vote for the two additional directors. This voting right would continue until we
have paid all past dividends on all preferred stock.

     Without the vote of at least 80% of the outstanding shares of Series C
preferred stock, we may not amend any provision in our charter so as to
adversely affect the powers, preferences, privileges or rights of the Series C
preferred stock.

     Without the approval of the holders, voting together as a single class, of
80% of all the shares of Series C preferred stock then outstanding and all
shares of any other series of the preferred stock of Apache ranking equally as
to dividends or upon liquidation, including the Series B preferred stock, we
will not:

     - issue, authorize or increase the authorized amount of, or issue or
       authorize any obligation or security convertible into or evidencing a
       right to purchase, any stock of any class ranking prior to the Series C
       preferred stock as to dividends or upon liquidation; or

     - reclassify any authorized Apache stock into any stock of any class, or
       any obligation or security convertible into or evidencing a right to
       purchase such stock, ranking prior to the Series C preferred stock,

provided that no such vote will be required for Apache to take any of these
actions to issue, authorize or increase the authorized amount of, or issue or
authorize any obligation or security convertible into or evidencing a right to
purchase, any stock ranking equally with or junior to the Series C preferred
stock.

     Without the approval of the holders of at least a majority of the shares of
Series C preferred stock then outstanding, we will not become a party to any
merger, conversion, consolidation or compulsory share exchange unless the terms
of that transaction do not provide for a change in the terms of the Series C
preferred stock and the Series C preferred stock ranks equally with or prior to
any capital stock of the surviving corporation as to dividends or upon
liquidation, dissolution or winding up, other than prior-ranking Apache stock
previously authorized with the consent of holders of the Series C preferred
stock.

     The depositary shares representing Series C preferred stock are listed on
the New York Stock Exchange under the symbol "APAPrC."

     UNDESIGNATED PREFERRED STOCK

     This summary of the undesignated preferred stock discusses terms and
conditions may apply to preferred stock offered under this prospectus. The
applicable prospectus supplement will describe the particular terms of each

     - the designation of the series of preferred stock;

     - the number of shares of preferred stock offered, the liquidation
       preference per share and the offering price of the preferred stock;

     - the dividend rate or rates of the shares, the method or methods of
       calculating the dividend rate or rates, the dates on which dividends, if
       declared, will be payable, and whether or not the dividends are to be
       cumulative and, if cumulative, the date or dates from which dividends
       will be cumulative;

     - the amounts payable on shares of the preferred stock in the event of our
       voluntary or involuntary liquidation, dissolution or winding up;

     - the redemption rights and price or prices, if any, for the shares of

       stock if dividend or other payments are not made on the preferred stock;

       prices, and any adjustment or other terms and conditions upon which the
       conversion exchange shall be made;

       our certificate of incorporation;

     - any listing of the preferred stock on any securities exchange; and

stock, at any time or from time to time, with such powers, preferences, rights
and qualifications, limitations or restrictions as the board of directors
determines, and without further action of the stockholders, including holders of
our then outstanding preferred stock, if any.

STOCKHOLDER RIGHTS PLAN

     In 1995, our board of directors adopted a stockholder rights plan to
replace the former plan adopted in 1986. Under our stockholder rights plan, each
of our common stockholders received a dividend of one "preferred stock purchase
right" for each outstanding share of common stock that the stockholder owned. We
refer to these preferred stock purchase rights as the "rights." Unless the
rights have been previously redeemed, all shares of Apache common stock are
issued with rights. The rights trade automatically with our shares of common
stock and become exercisable only under certain circumstances described below.

     The purpose of the rights is to encourage potential acquirors to negotiate
with our board of directors before attempting a takeover bid and to provide our
board of directors with leverage in negotiating on behalf of our stockholders
the terms of any proposed takeover. The rights may have certain anti-takeover
effects. They should not, however, interfere with any merger or other business
combination approved by our board of directors.

                                        11


     The following description is a summary of all the material terms of our
stockholder rights plan. It does not restate these terms in their entirety. We
urge you to read our stockholder rights plan because it, and not this
description, defines the terms and provisions of our plan. Our stockholder
rights plan is incorporated by reference as an exhibit to the registration
statement that includes this prospectus. You may obtain a copy at no charge by
writing to us at the address listed under the caption "Where You Can Find More
Information."

  Exercise of Rights

     Until a right is exercised, the holder of a right will not have any rights
as a stockholder. When the rights become exercisable, holders of the rights will
be able to purchase from us 1/10,000th of a share of our Series A preferred
stock, at a purchase price of $100, subject to adjustment, per 1/10,000th of a
share.

     In general, the rights will become exercisable upon the earlier of:

     - ten calendar days after a public announcement that a person or group has
       acquired beneficial ownership of 20% or more of the outstanding shares of
       our common stock; or

     - ten business days after the beginning of a tender offer or exchange offer
       that would result in a person or group beneficially owning 30% or more of
       our common stock.

  Flip in Event

     If a person or group becomes the beneficial owner of 20% or more of our
common stock, then each right will then entitle its holder to receive, upon
exercise, a number of shares of our common stock which is equal to the exercise
price of the right divided by one-half of the market price of our common stock
on the date of the occurrence of this event. We refer to this occurrence as a
"flip in event." A flip in event does not occur if there is an offer for all of
our outstanding shares of common stock that our board of directors determines is
fair to our stockholders and in Apache's best interests.

  Flip Over Event

     If, at any time after a person or group becomes the beneficial owner of 20%
or more of our common stock, Apache is acquired in a merger or other transaction
in which Apache does not survive or in which our common stock is changed or
exchanged or 50% or more of Apache's assets or earning power is sold or
transferred, then each holder of a right will be entitled to receive, upon
exercise, a number of shares of common stock of the acquiring company in the
transaction equal to the exercise price of the right divided by one-half of the
market price of the acquiring company's common stock on the date of the
occurrence of this event. This exercise right will not occur if the merger or
other transaction follows an offer for all of our outstanding shares of common
stock that our board of directors determines is fair to our stockholders and in
Apache's best interests.

  Exchange of Rights

     At any time after a flip in event, our board of directors may exchange the
rights by providing to the holder one share of our common stock or 1/10,000th of
a share of our Series A preferred stock for each of the holder's rights.

  Redemption of Rights

     At any time before a flip in event, we may redeem the rights at a price of
$.01 per right. The rights will expire on the close of business on January 31,
2006, subject to earlier expiration or termination as described in our
stockholder rights plan.

     Unless and until the rights become exercisable, they will be transferred
with and only with the shares of Apache common stock.

                                        12


ANTI-TAKEOVER EFFECT OF PROVISIONS OF APACHE'S CHARTER AND BYLAWS AND DELAWARE
LAW

     Apache's charter and bylaws include provisions designed to prevent the use
of certain tactics in connection with a potential takeover of Apache. Please
refer to our charter and bylaws that are incorporated by reference into the
registration statement that includes this prospectus. You may obtain copies at
no charge by writing to us at the address listed under the caption "Where You
Can Find More Information."

     Certain provisions of Delaware law described below also have an
anti-takeover effect.

  Apache's Bylaws

     Apache's board of directors is divided into three classes, with directors
serving staggered three-year terms.

  Apache's Charter

     Article Nine provides that Apache's board of directors is divided into
three classes, with directors serving staggered three-year terms.

     Article Twelve generally stipulates that the affirmative vote of 80% of our
voting shares is required to adopt any agreement for the merger or consolidation
with or into any other corporation which is the beneficial owner of more than 5%
of our voting shares. Article Twelve further provides that such 80% approval is
necessary to authorize any sale or lease of assets between Apache and any
beneficial holder of 5% or more of our voting shares.

     Article Fourteen contains a "fair price" provision which requires that any
tender offer made by a beneficial owner of more than 5% of our outstanding
voting stock in connection with any:

     - plan of merger, consolidation or reorganization;

     - sale or lease of substantially all of our assets; or

     - issuance of our equity securities to the 5% stockholder

must provide at least as favorable terms to each holder of common stock other
than the stockholder making the tender offer.

     Article Fifteen contains an "anti-greenmail" mechanism which prohibits
Apache from acquiring any voting stock from the beneficial owner of more than 5%
of Apache's outstanding voting stock, except for acquisitions pursuant to a
tender offer to all holders of voting stock on the same price, terms and
conditions, acquisitions in compliance with Rule 10b-18 of the Securities
Exchange Act of 1934 and acquisitions at a price not exceeding the market value
per share.

     Article Sixteen prohibits the stockholders from acting by written consent
in lieu of a meeting.

     The affirmative vote of 80% of the voting shares is required to amend or
adopt any provision inconsistent with Articles Nine, Twelve, Fourteen and
Sixteen.

  Business Combinations with Interested Stockholders Under Delaware Law

     Section 203 of the Delaware General Corporation Law prevents a publicly
held corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless:

     - before the date on which the person became an interested stockholder, the
       board of directors of the corporation approved either the business
       combination or the transaction in which the person became an interested
       stockholder;

     - the interested stockholder owned at least 85% of the outstanding voting
       stock of the corporation at the beginning of the transaction in which it
       became an interested stockholder, excluding stock held
                                        13


       by directors who are also officers of the corporation and by employee
       stock plans that do not provide participants with the rights to determine
       confidentially whether shares held subject to the plan will be tendered
       in a tender or exchange offer; or

     - on or after the date on which the interested stockholder became an
       interested stockholder, the business combination is approved by the board
       of directors and the holders of two-thirds of the outstanding voting
       stock of the corporation voting at a meeting, excluding the voting stock
       owned by the interested stockholder.

     As defined in Section 203, an "interested stockholder" is generally a
person owning 15% or more of the outstanding voting stock of the corporation. As
defined in Section 203, a "business combination" includes mergers,
consolidations, stock and assets sales and other transactions with the
interested stockholder.

     The provisions of Section 203 may have the effect of delaying, deferring or
preventing a change of control of Apache.

                        DESCRIPTION OF DEPOSITARY SHARES

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the depositary
shares that we may offer under this prospectus and the related deposit
agreements and depositary receipts. Specific deposit agreements and depositary
receipts will contain additional important terms and provisions. The forms of
the applicable deposit agreement and depositary receipt will be incorporated by
reference as an exhibit to the registration statement that includes this
prospectus before we issue any depositary shares.

     This summary of depositary agreements, depositary shares and depositary
receipts relates to terms and conditions applicable to these types of securities
generally. The particular terms of any series of depositary shares will be
summarized in the applicable prospectus supplement. If indicated in the
applicable prospectus supplement, the terms of any series may differ from the
terms summarized below.

GENERAL

     We may elect to offer fractional shares of preferred stock rather than full
shares of preferred stock. If so, we will issue "depositary receipts" for these
"depositary shares." Each depositary share will represent a fraction of a share
of a particular series of preferred stock. Each holder of a depositary share
will be entitled, in proportion to the fraction of preferred stock represented
by that depositary share, to all the rights, preferences and privileges of the
preferred stock, including dividend, voting, redemption, conversion and
liquidation rights, if any, and all the limitations of the preferred stock. We
will enter into a deposit agreement with a depositary, which will be named in
the applicable prospectus supplement.

     In order to issue depositary shares, we will issue preferred stock and
immediately deposit these shares with the depositary. The depositary will then
issue and deliver depositary receipts to the persons who purchase depositary
shares. Each whole depositary share issued by the depositary may represent a
fraction of a share of preferred stock held by the depositary. The depositary
will issue depositary receipts in a form that reflects whole depositary shares,
and each depositary receipt may evidence any number of whole depositary shares.

     Pending the preparation of definitive engraved depositary receipts, if any,
a depositary may, upon our written order, issue temporary depositary receipts,
which will temporarily entitle the holders to all the rights pertaining to the
definitive depositary receipts. We will bear the costs and expenses of promptly
preparing definitive depositary receipts and of exchanging the temporary
depositary receipts for such definitive depositary receipts.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The depositary will distribute all cash and non-cash distributions it
receives with respect to the underlying preferred stock to the record holders of
depositary shares in proportion to the number of depositary shares they hold,
subject to any obligations of the record holders to file proofs, certificates
and other information and to pay any taxes or other governmental charges. In the
case of any non-cash distribution, Apache may determine that the distribution
cannot be made proportionately or the depositary may determine that it may not
be feasible to make the distribution. If so, the depositary may, with our
approval, adopt a method it deems equitable and practicable to effect the
distribution, including the sale, public or private, of the securities or other
non-cash property it receives in the distribution at a place and on terms it
deems proper. The amounts distributed by the depositary will be reduced by any
amount required to be withheld by Apache or the depositary on account of taxes.

REDEMPTION OF DEPOSITARY SHARES

     If the shares of preferred stock that underlie the depositary shares are
redeemable and we redeem the preferred stock, the depositary will redeem the
depositary shares from the proceeds it receives from the redemption of the
preferred stock it holds. The depositary will redeem the number of depositary
shares that represent the amount of underlying preferred stock that we have
redeemed. The redemption price for

                                        15


depositary shares will be in proportion to the redemption price per share that
we paid for the underlying preferred stock. If we redeem less than all of the
depositary shares, the depositary will select which depositary shares to redeem
by lot, or some substantially equivalent method.

     After a redemption date is fixed, the depositary shares to be redeemed no
longer will be considered outstanding. The rights of the holders of the
depositary shares will cease, except for the rights to receive money or other
property upon redemption. In order to redeem their depositary shares, holders
must surrender their depositary receipts to the depositary.

VOTING THE PREFERRED STOCK

     When the depositary receives notice about any meeting at which the holders
of preferred stock are entitled to vote, the depositary will mail the
information contained in the notice to the record holders of depositary shares
related to that preferred stock. Each record holder of depositary shares on the
record date, which will be the same date as the record date for the preferred
stock, will be entitled to instruct the depositary on how to vote the shares of
preferred stock represented by that holder's depositary shares. The depositary
will endeavor, to the extent practicable, to vote the preferred stock
represented by the depositary shares in accordance with these instructions. If
the depositary does not receive instructions from the holders of the depositary
shares, the depositary will abstain from voting the preferred stock that
underlies those depositary shares.

WITHDRAWAL OF PREFERRED STOCK

     If a holder of depositary receipts surrenders those depositary receipts at
the corporate office (as defined in the deposit agreement) of the depositary, or
any other office as the depositary may designate, and pays any taxes, charges or
fees, that holder is entitled to delivery at the corporate office of
certificates evidencing the number of shares of preferred stock, but only in
whole shares, and any money and other property represented by those depositary
receipts. If the depositary receipts we deliver evidence a number of depositary
shares in excess of the number of whole shares of preferred stock to be
withdrawn, the depositary will deliver to us at the same time a new depositary
receipt evidencing that excess number of depositary shares. We do not expect
that there will be any public trading market for the shares of preferred stock
except those represented by the depositary shares.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     Apache and the depositary can agree, at any time, to amend the form of
depositary receipt and any provisions of the deposit agreement. However, if an
amendment has a material adverse effect on the rights of the holders of related
depositary shares, the holders of at least a majority of the depositary shares
then outstanding must first approve the amendment. Every holder of a depositary
receipt at the time an amendment becomes effective will be bound by the amended
deposit agreement. However, subject to any conditions in the deposit agreement
or applicable law, no amendment can impair the right of any holder of a
depositary share to receive shares of the related preferred stock, or any money
or other property represented by the depositary shares, when they surrender
their depositary receipts.

     Unless otherwise specified in the applicable prospectus supplement, the
deposit agreement may be terminated by us or by the depositary if there has been
a final distribution in respect of the preferred stock in connection with any
liquidation, dissolution or winding up of Apache and that distribution has been
distributed to the holders of depositary receipts.

CHARGES OF DEPOSITARY

     We will pay all transfer and other taxes and the government charges that
relate solely to the depositary arrangements. We will also pay the charges of
each depositary, including charges in connection with the initial deposit of the
related series of preferred stock, the initial issuance of the depositary
shares, and all withdrawals of shares of the related series of preferred stock.
However, holders of depositary shares

                                        16


will be required to pay transfer and other taxes and government charges, as
provided in the deposit agreement.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The depositary may resign at any time. We may remove the depositary at any
time. Any resignation or removal will take effect when we appoint a successor
depositary. We must appoint the successor depositary within 60 days after
delivery of the notice of resignation or removal. The successor depositary must
be a bank or trust company that has its principal office in the United States
and has a combined capital and surplus of at least $50,000,000.

MISCELLANEOUS

     We will be required to furnish certain information to the holders of the
preferred stock underlying any depositary shares. The depositary, as the holder
of the underlying preferred stock, will forward any report or information it
receives from us to the holders of depositary shares.

     Neither the depositary nor Apache will be liable if its ability to perform
its obligations under the deposit agreement is prevented or delayed by law or
any circumstance beyond its control. Each of Apache and the depositary will be
obligated to use its best judgment and to act in good faith in performing its
duties under the deposit agreement. Each of Apache and the depositary will be
liable only for gross negligence and willful misconduct in performing its duties
under the deposit agreement. They will not be obligated to appear in, prosecute
or defend any legal proceeding with respect to any depositary receipts,
depositary shares or preferred stock unless they receive what they, in their
sole discretion, determine to be a satisfactory indemnity from one or more
holders of the depositary shares. Apache and the depositary will evaluate any
proposed indemnity in order to determine whether the financial protection
afforded by the indemnity is sufficient to reduce each party's risk to a
satisfactory and customary level. Apache and the depositary may rely on the
advice of legal counsel or accountants of their choice. They may also rely on
information provided by persons they believe, in good faith, to be competent,
and on documents they believe, in good faith, to be genuine.

     The applicable prospectus supplement will identify the depositary's
corporate trust office. Unless the prospectus supplement indicates otherwise,
the depositary will act as transfer agent and registrar for depositary receipts,
and if we redeem shares of preferred stock, the depositary will act as
redemption agent for the corresponding depositary receipts.

TITLE

     Apache, each depositary and any agent of Apache or the applicable
depositary may treat the registered owner of any depositary share as the
absolute owner of the depositary shares for all purposes, including making
payment, regardless of whether any payment in respect of the depositary share is
overdue and regardless of any notice to the contrary. See "Book-Entry
Securities" below.

                                        17


                         DESCRIPTION OF DEBT SECURITIES

     The following description, together with any applicable prospectus
supplement, summarizes all the material terms and provisions of the debt
securities that we may offer under this prospectus and the related trust
indentures. We will issue the senior debt securities under a senior indenture,
dated as of November 2, 1995, as supplemented on October 31, 1996, between us
and The Chase Manhattan Bank, as trustee. We will issue the subordinated debt
securities under a subordinated indenture to be executed in the future by us and
The Chase Manhattan Bank, as trustee. The senior indenture and the subordinated
indenture are together referred to in this prospectus as the "indentures." The
senior debt securities and the subordinated debt securities are collectively
referred to in this prospectus as the "debt securities." The Chase Manhattan
Bank or any successor, in its capacity as trustee under either or both of the
indentures, is referred to as the "trustee" for purposes of this section. The
indentures contain and the debt securities, when issued, will contain additional
important terms and provisions. The indentures are, and the debt securities
prior to their issuance will be, filed as exhibits to the registration statement
that includes this prospectus.

     This summary of the indentures and the debt securities relates to terms and
conditions applicable to the debt securities generally. The particular terms of
any series of debt securities will be summarized in the applicable prospectus
supplement. If indicated in the prospectus supplement, the terms of any series
may differ from the terms summarized below.

     Neither indenture limits the amount of debt securities we may issue under
it, and each provides that additional debt securities of any series may be
issued up to the aggregate principal amount that we authorize from time to time.
Debt securities may also be issued pursuant to the indentures in transactions
exempt from the registration requirements of the Securities Act of 1933. Those
debt securities will not be considered in determining the aggregate amount of
securities issued under this prospectus.

     Unless otherwise indicated in the applicable prospectus supplement, we will
issue the debt securities in denominations of $1,000 or integral multiples of
$1,000.

     Principal and any premium and interest in respect to the debt securities
will be payable, and the debt securities will be transferable, at the corporate
trust office of the trustee, unless we specify otherwise in the applicable
prospectus supplement. At our option, however, payment of interest may be made
by check mailed to the registered holders of the debt securities at their
registered addresses.

     We will describe special U.S. federal income tax and other considerations
relating to debt securities denominated in foreign currencies or units of two or
more foreign currencies in the applicable prospectus supplement.

     Unless we specify otherwise in the applicable prospectus supplement, the
covenants contained in the indentures and the debt securities will not provide
special protection to holders of debt securities if we enter into a highly
leveraged transaction, recapitalization or restructuring. Nothing in the
indentures or the debt securities will in any way limit the amount of
indebtedness or securities that we or our subsidiaries, as defined in the
indenture, may incur or issue.

GENERAL

     The prospectus supplement relating to the particular series of debt
securities being offered will specify whether they are senior or subordinated
debt securities and the amounts, prices and terms of those debt securities.
These terms may include:

     - the designation, aggregate principal amount and authorized denominations
       of the debt securities;

     - the date or dates on which the debt securities will mature;

     - the percentage of the principal amount at which the debt securities will
       be issued;

     - the date on which the principal of the debt securities will be payable;

                                        18


     - whether the debt securities will be issued as registered securities,
       bearer securities or a combination of the two;

     - whether the debt securities will be issued in the form of one or more
       global securities and whether such global securities will be issued in a
       temporary global form or permanent global form;

     - the currency or currencies or currency unit or units of two or more
       currencies in which debt securities are denominated, for which they may
       be purchased, and in which principal and any premium and interest is
       payable;

     - if the currency or currencies or currency unit or units for which debt
       securities may be purchased or in which principal and any premium and
       interest may be paid is at our election or at the election of a
       purchaser, the manner in which an election may be made and its terms;

     - the annual rate or rates, which may be fixed or variable, or the method
       of determining the rate or rates at which the debt securities will bear
       any interest, whether by remarketing, auction, formula or otherwise;

     - the date or dates from which any interest will accrue and the date or
       dates on which such interest will be payable;

     - a description of any provisions providing for redemption, exchange or
       conversion of the debt securities at our option, a holder's option or
       otherwise, and the terms and provisions of such a redemption, exchange or
       conversion;

     - information with respect to book-entry procedures relating to global debt
       securities;

     - any sinking fund terms;

     - whether and under what circumstances we will pay "additional amounts," as
       defined in the indentures, on the debt securities to any holder who is a
       "United States alien," as defined in the indentures, in respect of any
       tax, assessment or governmental charge; the term "interest," as used in
       this prospectus, includes any additional amounts;

     - any modifications or additions to, or deletions of, any of the events of
       default or covenants of Apache with respect to the debt securities that
       are described in this prospectus;

     - if either or both of the sections of the applicable indenture relating to
       defeasance and covenant defeasance are not applicable to the debt
       securities, or if any covenants in addition to or other than those
       specified in the applicable indenture shall be subject to covenant
       defeasance;

     - any deletions from, or modifications or additions to, the provisions of
       the indentures relating to satisfaction and discharge in respect of the
       debt securities;

     - any index or other method used to determine the amount of payments of
       principal of, and any premium and interest on, the debt securities; and

     - any other specific terms of the debt securities.

     We are not obligated to issue all debt securities of any one series at the
same time. The debt securities of any one series may not bear interest at the
same rate or mature on the same date.

     If any of the debt securities are sold for foreign currencies or foreign
currency units or if the principal of, or any premium or interest on, any series
of debt securities is payable in foreign currencies or foreign currency units,
we will describe the restrictions, elections, tax consequences, specific terms
and other information with respect to those debt securities and such foreign
currencies or foreign currency units in the applicable prospectus supplement.

     Other than as described below under "The Senior Indenture Limits Our
Ability to Incur Liens," "The Senior Indenture Limits Our Ability to Engage in
Sale/Leaseback Transactions" and "We Are Obligated to Purchase Debt Securities
upon a Change in Control," and as may be described in the

                                        19


applicable prospectus supplement, the indentures do not limit our ability to
incur indebtedness or afford holders of debt securities protection in the event
of a decline in our credit quality or if we are involved in a takeover,
recapitalization or highly leveraged or similar transaction.

RANKING

  Senior Debt Securities

     Unless otherwise indicated in the applicable prospectus supplement, our
obligation to pay the principal of, and any premium and interest on, the senior
debt securities will be unsecured and will rank equally with all of our other
unsecured unsubordinated indebtedness.

  Subordinated Debt Securities

     Our obligation to pay the principal of, and any premium and interest on,
any subordinated debt securities will be unsecured and will rank subordinate and
junior in right of payment to all senior indebtedness to the extent provided in
the subordinated indenture and the terms of those subordinated debt securities,
as described below and in any applicable prospectus supplement, which may make
deletions from, or modifications or additions to, the subordination terms
described below.

     Upon any payment or distribution of assets or securities of Apache to
creditors upon any liquidation, dissolution, winding-up, reorganization, or any
bankruptcy, insolvency, receivership or similar proceedings in connection with
any insolvency or bankruptcy proceeding of Apache, the holders of senior
indebtedness will first be entitled to receive payment in full of the senior
indebtedness before the holders of subordinated debt securities will be entitled
to receive any payment or distribution in respect of the subordinated debt
securities.

     No payments on account of principal or any premium or interest in respect
of the subordinated debt securities may be made if there has occurred and is
continuing a default in any payment with respect to senior indebtedness or an
event of default with respect to any senior indebtedness resulting in the
acceleration of its maturity, or if any judicial proceeding is pending with
respect to any default.

     "Indebtedness," for purposes of the subordinated indenture, means:

     - indebtedness for borrowed money or for the unpaid purchase price of real
       or personal property of, or guaranteed by, Apache, other than accounts
       payable arising in the ordinary course of business payable on terms
       customary in the trade;

     - indebtedness secured by any mortgage, lien, pledge, security interest or
       encumbrances of any kind or payable out of the proceeds of production
       from property;

     - indebtedness which is evidenced by mortgages, notes, bonds, securities,
       acceptances or other instruments;

     - indebtedness which must be capitalized as liabilities under generally
       accepted accounting principles;

     - liabilities under interest rate swap, exchange, collar or cap agreements
       and all other agreements or arrangements designed to protect against
       fluctuations in interest rates or currency exchange rates;

     - liabilities under commodity hedge, commodity swap, exchange, collar or
       cap agreements, fixed price agreements and all other agreements or
       arrangements designed to protect against fluctuations in oil and gas
       prices;

     - guarantees and endorsements of obligations of others, directly or
       indirectly, and all other repurchase agreements and indebtedness in
       effect guaranteed through an agreement, contingent or otherwise, to
       purchase that indebtedness, or to purchase or sell property, or to
       purchase or sell services, primarily for the purpose of enabling the
       debtor to make payment of the indebtedness or to assure the owner of the
       indebtedness against loss, or to supply funds to or in any manner invest
       in the debtor, or

                                        20


       otherwise to assure a creditor against loss (but excluding guarantees and
       endorsements of notes, bills and checks made in the ordinary course of
       business); and

     - indebtedness relative to the amount of all letters of credit;

provided, however, that such term shall not include any amounts included as
deferred credits on the financial statements of Apache and computed in
accordance with generally accepted accounting principles.

     "Senior indebtedness," for purposes of the subordinated indenture, means
all indebtedness, whether outstanding on the date of execution of the
subordinated indenture or thereafter created, assumed or incurred, except
indebtedness ranking equally with the subordinated debt securities or
indebtedness ranking junior to the subordinated debt securities.

     "Indebtedness ranking equally with the subordinated debt securities," for
purposes of the subordinated indenture, means indebtedness, whether outstanding
on the date of execution of the subordinated indenture or thereafter created,
assumed or incurred, to the extent the indebtedness specifically by its terms
ranks equally with and not prior to the subordinated debt securities in the
right of payment upon the happening of the dissolution, winding-up, liquidation
or reorganization of Apache. The securing of any indebtedness otherwise
constituting indebtedness ranking equally with the subordinated debt securities
will not prevent the indebtedness from constituting indebtedness ranking equally
with the subordinated debt securities.

     "Indebtedness ranking junior to the subordinated debt securities," for
purposes of the subordinated indenture, means any indebtedness, whether
outstanding on the date of execution of the subordinated indenture or thereafter
created, assumed or incurred, to the extent the indebtedness by its terms ranks
junior to and not equally with or prior to

     - the subordinated debt securities, and

     - any other indebtedness ranking equally with the subordinated debt
       securities,

in right of payment upon the happening of the dissolution, winding-up,
liquidation or reorganization of Apache. The securing of any indebtedness
otherwise constituting indebtedness ranking junior to the subordinated debt
securities will not prevent the indebtedness from constituting indebtedness
ranking junior to the subordinated debt securities.

INTEREST RATES AND DISCOUNTS

     The debt securities will earn interest at a fixed or floating rate or rates
for the period or periods of time specified in the applicable prospectus
supplement. Unless otherwise specified in the applicable prospectus supplement,
the debt securities will bear interest on the basis of a 360-day year consisting
of twelve 30-day months.

     We may sell debt securities at a substantial discount below their stated
principal amount, bearing no interest or interest at a rate that at the time of
issuance is below market rates. Federal income tax consequences and special
considerations that apply to any series will be described in the applicable
prospectus supplement.

EXCHANGE, REGISTRATION AND TRANSFER

     Registered securities of any series that are not global securities will be
exchangeable for other registered securities of the same series and of like
aggregate principal amount and tenor in different authorized denominations. In
addition, if debt securities of any series are issuable as both registered
securities and bearer securities, the holder may choose, upon written request,
and subject to the terms of the applicable indenture, to exchange bearer
securities and the appropriate related coupons of that series into registered
securities of the same series of any authorized denominations and of like
aggregate principal amount and tenor. Bearer securities with attached coupons
surrendered in exchange for registered securities between a regular record date
or a special record date and the relevant date for interest payment shall be
surrendered without the coupon relating to the interest payment date. Interest
will not be payable

                                        21


with respect to the registered security issued in exchange for that bearer
security. That interest will be payable only to the holder of the coupon when
due in accordance with the terms of the indenture. Bearer securities will not be
issued in exchange for registered securities.

     You may present registered securities for registration of transfer,
together with a duly executed form of transfer, at the office of the security
registrar or at the office of any transfer agent designated by us for that
purpose with respect to any series of debt securities and referred to in the
applicable prospectus supplement. This may be done without service charge but
upon payment of any taxes and other governmental charges as described in the
applicable indenture. The security registrar or the transfer agent will effect
the transfer or exchange upon being satisfied with the documents of title and
identity of the person making the request. We have appointed the trustee as
security registrar for each indenture. If a prospectus supplement refers to any
transfer agents initially designated by us with respect to any series of debt
securities in addition to the security registrar, we may at any time rescind the
designation of any of those transfer agents or approve a change in the location
through which any of those transfer agents acts. However, if debt securities of
a series are issuable solely as registered securities, we will be required to
maintain a transfer agent in each place of payment for that series, and if debt
securities of a series are issuable as bearer securities, we will be required to
maintain a transfer agent in a place of payment for that series located in
Europe in addition to the security registrar. We may at any time designate
additional transfer agents with respect to any series of debt securities.

     In the event of any redemption, we will not be required to:

     - issue, register the transfer of or exchange debt securities of any series
       during a period beginning at the opening of business 15 days before any
       selection of debt securities of that series to be redeemed and ending at
       the close of business on the day of mailing of the relevant notice of
       redemption; or

     - register the transfer of or exchange any registered security, or portion
       thereof, called for redemption, except the unredeemed portion of any
       registered security being redeemed in part.

PAYMENT AND PAYING AGENTS

     Unless we specify otherwise in the applicable prospectus supplement,
payment of principal of, and any premium and interest on, bearer securities will
be payable in accordance with any applicable laws and regulations, at the
offices of those paying agents outside the United States that we may designate
at various times. We will make interest payments on bearer securities and the
attached coupons on any interest payment date only against surrender of the
coupon relating to that interest payment date. No payment with respect to any
bearer security will be made at any of our offices or agencies in the United
States by check mailed to any U.S. address or by transfer to an account
maintained with a bank located in the United States. If, however, but only if,
payment in U.S. dollars of the full amount of principal of, and any premium and
interest on, bearer securities denominated and payable in U.S. dollars at all
offices or agencies outside the United States is illegal or effectively
precluded by exchange controls or other similar restrictions, then those
payments will be made at the office of our paying agent in the Borough of
Manhattan, The City of New York.

     Unless we specify otherwise in the applicable prospectus supplement,
payment of principal of, and any premium and interest on, registered securities
will be made at the office of the paying agent or paying agents that we
designate at various times. However, at our option, we may make interest
payments by check mailed to the address, as it appears in the security register,
of the person entitled to the payments. Unless we specify otherwise in the
applicable prospectus supplement, we will make payment of any installment of
interest on registered securities to the person in whose name that registered
security is registered at the close of business on the regular record date for
such interest.

     Unless we specify otherwise in the applicable prospectus supplement, the
Corporate Trust Office of the trustee in the Borough of Manhattan, The City of
New York, will be designated:

     - as our sole paying agent for payments with respect to debt securities
       that are issuable solely as registered securities; and

                                        22


     - as our paying agent in the Borough of Manhattan, The City of New York,
       for payments with respect to debt securities, subject to the limitation
       described above in the case of bearer securities, that are issuable
       solely as bearer securities or as both registered securities and bearer
       securities.

     We will name any paying agents outside the United States and any other
paying agents in the United States initially designated by us for the debt
securities in the applicable prospectus supplement. We may at any time designate
additional paying agents or rescind the designation of any paying agent or
approve a change in the office through which any paying agent acts. However, if
debt securities of a series are issuable solely as registered securities, we
will be required to maintain a paying agent in each place of payment for that
series. If debt securities of a series are issuable as bearer securities, we
will be required to maintain:

     - a paying agent in the Borough of Manhattan, The City of New York, for
       payments with respect to any registered securities of the series and for
       payments with respect to bearer securities of the series in the
       circumstance described above, but not otherwise; and

     - a paying agent in a place of payment located outside the United States
       where debt securities of that series and any attached coupons may be
       presented and surrendered for payment.

     However, if the debt securities of that series are listed on the London
Stock Exchange, the Luxembourg Stock Exchange or any other stock exchange
located outside the United States, and if the stock exchange requires it, we
will maintain a paying agent in London or Luxembourg or any other required city
located outside the United States for those debt securities.

     All monies we pay to a paying agent for the payment of principal of, and
any premium or interest on, any debt security or coupon that remains unclaimed
at the end of two years after becoming due and payable will be repaid to us.
After that time, the holder of the debt security or coupon will look only to us
for payments out of those repaid amounts.

GLOBAL SECURITIES

     The debt securities of a series may be issued in whole or in part in the
form of one or more global certificates that we will deposit with a depository
identified in the applicable prospectus supplement. Global securities may be
issued in either registered or bearer form and in either temporary or permanent
form. Unless and until it is exchanged in whole or in part for the individual
debt securities it represents, a global security may not be transferred except
as a whole:

     - by the applicable depositary to a nominee of the depository;

     - by any nominee to the depository itself or another nominee; or

     - by the depositary or any nominee to a successor depository or any nominee
       of the successor.

     To the extent not described below and under the heading "Book-Entry
Securities," we will describe the terms of the depository arrangement with
respect to a series of debt securities in the applicable prospectus supplement.
We anticipate that the following provisions will generally apply to depository
arrangements.

     As long as the depository for a global security, or its nominee, is the
registered owner of that global security, the depository or nominee will be
considered the sole owner or holder of the debt securities represented by the
global security for all purposes under the applicable indenture. Except as
provided under "Book-Entry Securities" or in any applicable prospectus
supplement, owners of beneficial interests in a global security:

     - will not be entitled to have any of the underlying debt securities
       registered in their names;

     - will not receive or be entitled to receive physical delivery of any of
       the underlying debt securities in definitive form; and
                                        23


     - will not be considered the owners or holders under the indenture relating
       to those debt securities.

     The laws of some states require that certain purchasers of securities take
physical delivery of securities in definitive form. These laws may impair your
ability to transfer beneficial interests in a global security.

     Payments of principal of, and any premium and interest on, individual debt
securities represented by a global security registered in the name of a
depository or its nominee will be made to the depository or its nominee as the
registered owner of the global security representing such debt securities.
Neither we, the trustee, any paying agent nor the registrar for the debt
securities will be responsible for any aspect of the records relating to or
payments made by the depository or any participants on account of beneficial
interests of the global security.

     For a description of the depository arrangements for global securities held
by The Depository Trust Company, see "Book-Entry Securities."

THE SENIOR INDENTURE LIMITS OUR ABILITY TO INCUR LIENS

     Unless we specify otherwise in the applicable prospectus supplement, the
senior indenture provides that neither we nor any of our subsidiaries may issue,
assume or guarantee any notes, bonds, debentures or other similar evidences of
indebtedness for money borrowed that are secured by a mortgage, lien, pledge,
security interest or other encumbrance -- defined in the indenture as
"liens" -- upon any of our property unless we provide that any and all senior
debt securities then outstanding shall be secured by a lien equally and ratably
with any and all other obligations by the lien. The restrictions on liens will
not, however, apply to:

     - liens existing on the date of the senior indenture or provided for under
       the terms of agreements existing on the date thereof;

     - liens securing all or part of the cost of exploring, producing,
       gathering, processing, marketing, drilling or developing any of our or
       our subsidiaries' properties, or securing indebtedness incurred to
       provide funds therefor or indebtedness incurred to finance all or part of
       the cost of acquiring, constructing, altering, improving or repairing any
       such property or assets, or securing indebtedness incurred to provide
       funds therefor;

     - liens securing only indebtedness owed by one of our subsidiaries to us
       and/or to one or more of our other subsidiaries;

     - liens on the property of any corporation or other entity existing at the
       time it becomes our subsidiary;

     - liens on any property to secure indebtedness incurred in connection with
       the construction, installation or financing of pollution control or
       abatement facilities or other forms of industrial revenue bond financing
       or indebtedness issued or guaranteed by the United States, any state or
       any department, agency or instrumentality of either or indebtedness
       issued to or guaranteed for the benefit of a foreign government, any
       state or any department, agency or instrumentality of either or an
       international finance agency or any division or department thereof,
       including the World Bank, the International Finance Corp. and the
       Multilateral Investment Guarantee Agency;

     - any extension, renewal or replacement or successive extensions, renewals
       or replacements of any lien referred to in the foregoing clauses that
       existed on the date of the senior indenture;

     - certain other liens incurred in the ordinary course of business; or

     - liens which secure "limited recourse indebtedness," as defined in the
       senior indenture.

                                        24


     In addition, the following types of transactions, among others, shall not
be deemed to create indebtedness secured by liens:

     - the sale or other transfer of crude oil, natural gas or other petroleum
       hydrocarbons in place for a period of time until, or in an amount such
       that, the transferee will receive as a result of the transfer a specified
       amount of money or of such crude oil, natural gas or other petroleum
       hydrocarbons;

     - the sale or other transfer of any other interest in property of the
       character commonly referred to as a production payment, overriding
       royalty, forward sale or similar interest; and

     - liens required by any contract or statute in order to permit us or one of
       our subsidiaries to perform any contract or subcontract made with or at
       the request of the U.S. government or any foreign government or
       international finance agency, any state or any department thereof, or any
       agency or instrumentality of either, or to secure partial, progress,
       advance or other payments to us or one of our subsidiaries by any of
       these entities pursuant to the provisions of any contract or statute.

THE SENIOR INDENTURE LIMITS OUR ABILITY TO ENGAGE IN SALE/LEASEBACK TRANSACTIONS

     Unless we specify otherwise in the applicable prospectus supplement, the
senior debt indenture provides that neither we nor any of our subsidiaries will
enter into any arrangement with any person, other than us or one of our
subsidiaries, to lease any property to ourselves or a subsidiary of ours for
more than three years. For the restriction to apply, we or one of our
subsidiaries must sell or plan to sell the property to the person leasing it to
us or our subsidiary or to another person to which funds have been or are to be
advanced on the security of the leased property. The limitation does not apply
where:

     - either we or our subsidiary would be entitled to create debt secured by a
       lien on the property to be leased in a principal amount equal to or
       exceeding the value of that sale/leaseback transaction;

     - since the date of the senior indenture and within a period commencing six
       months prior to the consummation of that arrangement and ending six
       months after the consummation of the arrangement, we have or our
       subsidiary has expended for any property an amount up to the net proceeds
       of that arrangement, including amounts expended for the acquisition,
       exploration, drilling or development thereof, and for additions,
       alterations, improvements and repairs to the property, and we designate
       such amount as a credit against that arrangement, with any of that amount
       not being so designated to be applied as set forth in the next item; or

     - during or immediately after the expiration of the 12 months after the
       effective date of that transaction, we apply to the voluntary redemption,
       defeasance or retirement of the senior debt securities and/or other
       senior indebtedness, as defined in the senior indenture, an amount equal
       to the greater of the net proceeds of the sale or transfer of the
       property leased in that transaction or the fair value of such property at
       the time of entering into such transaction, in either case adjusted to
       reflect the remaining term of the lease and any amount we utilize as set
       forth in the prior item; the amount will be reduced by the principal
       amount of senior indebtedness we voluntarily retire within that 12-month
       period.

EACH INDENTURE INCLUDES EVENTS OF DEFAULT

     Unless otherwise specified in the applicable prospectus supplement, any one
of the following events will constitute an "event of default" under each
indenture with respect to the debt securities of any series issued under that
indenture:

     - if we fail to pay any interest on any debt security of that series when
       due, and the failure continues for 30 days;

     - if we fail to pay principal of or any premium on the debt securities of
       that series when due and payable, either at maturity or otherwise;

     - if we fail to perform or we breach any of our other covenants or
       warranties in the applicable indenture or in the debt securities of that
       series -- other than a covenant or warranty included in
                                        25


       the applicable indenture solely for the benefit of a series of securities
       other than the debt securities of that series -- and that breach of
       failure continues for 60 days after written notice as provided in the
       applicable indenture;

     - certain events of bankruptcy, insolvency or reorganization involving us
       or any of our subsidiaries; and

     - any other event of default provided with respect to the debt securities
       of that series.

     Unless otherwise specified in the applicable prospectus supplement, either
of the following two events will also constitute an "event of default" under the
senior indenture with respect to any senior debt securities:

     - if any of our or any of our subsidiaries' indebtedness, as defined in the
       senior indenture, in excess of an aggregate of $25,000,000 in principal
       amount is accelerated under any event of default as defined in any
       mortgage, indenture or instrument and the acceleration has not been
       rescinded or annulled within 30 days after written notice as provided in
       the senior indenture has been given specifying such event of default and
       requiring us to cause that acceleration to be rescinded or annulled; or

     - if we or any of our subsidiaries fail to pay, bond or otherwise discharge
       within 60 days of entry, a judgment, court order or uninsured monetary
       damage award against us in excess of an aggregate of $25,000,000 which is
       not stayed on appeal or otherwise being appropriately contested in good
       faith.

     If an event of default with respect to the debt securities of any series,
other than an event of default described in the item above pertaining to certain
events of bankruptcy, insolvency or reorganization, occurs and is continuing,
either the trustee or the holders of at least 25% in aggregate principal amount
of the outstanding debt securities of that series may declare the principal
amount of the debt securities of that series to be due and payable immediately.
At any time after a declaration of acceleration has been made, but before a
judgment or decree for payment of money has been obtained by the trustee, and
subject to applicable law and certain other provisions of the applicable
indenture, the holders of a majority in aggregate principal amount of the debt
securities of that series may, under certain circumstances, rescind and annul
such acceleration. If an event of default occurs pertaining to certain events of
bankruptcy, insolvency or reorganization, the principal amount and accrued
interest -- or a lesser amount as provided for in the debt securities of that
series -- shall be immediately due and payable without any declaration or other
act by the trustee or any holder.

     Within 90 days after the occurrence of any event of default under an
indenture with respect to the debt securities of any series issued under that
indenture, the trustee must transmit notice of the event of default to the
holders of the debt securities of that series unless the event of default has
been cured or waived. The trustee may withhold the notice, however, except in
the case of a payment default, if and so long as the board of directors, the
executive committee or a trust committee of directors or responsible officers of
the trustee has in good faith determined that the withholding of the notice is
in the interest of the holders of debt securities of that series.

     If an event of default occurs and is continuing with respect to the debt
securities of any series, the trustee may in its discretion proceed to protect
and enforce its rights and the rights of the holders of debt securities of that
series by all appropriate judicial proceedings.

     Subject to the duty of the trustee during any default to act with the
required standard of care, the trustee is under no obligation to exercise any of
its rights or powers under an indenture at the request or direction of any of
the holders of debt securities issued under that indenture, unless the holders
offer the trustee reasonable indemnity. Subject to indemnifying the trustee, and
subject to applicable law and certain other provisions of each indenture, the
holders of a majority in aggregate principal amount of the outstanding debt
securities of a series issued under that indenture may direct the time, method
and place of conducting any proceeding for any remedy available to the trustee,
or exercising any trust or power conferred on the trustee, with respect to the
debt securities of that series.

                                        26


WE ARE OBLIGATED TO PURCHASE DEBT SECURITIES UPON A CHANGE IN CONTROL

     If a change in control, as defined in each indenture, occurs, we must mail
within 15 days a written notice regarding the change in control to the trustee
and to every holder of the debt securities of each series issued under that
indenture. The notice must also be published at least once in an authorized
newspaper, as defined in each indenture, and must state:

     - the event causing the change in control and the date of the event;

     - the date by which notice of the change in control is required by the
       applicable indenture to be given;

     - the date, 35 business days after the occurrence of the change in control,
       by which we must purchase debt securities we are obligated to purchase
       pursuant to the selling holder's exercise of rights on change in control;

     - the price we must pay for the debt securities we are obligated to
       purchase;

     - the name and address of the trustee;

     - the procedure for surrendering debt securities to the trustee or other
       designated office or agent for payment;

     - a statement of our obligation to make prompt payment on proper surrender
       of the debt securities;

     - the procedure for holders' exercise of rights of sale of the debt
       securities; and

     - the procedures by which a holder may withdraw such a notice after it is
       given.

     After we give this notice we will be obligated, at the election of each
holder, to purchase the applicable debt securities. Under each indenture, a
change in control is deemed to have occurred when:

     - any event requiring the filing of any report under or in response to
       Schedule 13D or 14D-1 pursuant to the Securities Exchange Act of 1934
       disclosing beneficial ownership of either 50% or more of our common stock
       then outstanding or 50% or more of the voting power of our voting stock
       then outstanding;

     - the completion of any sale, transfer, lease, or conveyance of our
       properties and assets substantially as an entirety to any person or
       persons that is not our subsidiary, as those terms are defined in each
       indenture; or

     - the completion of a consolidation or merger of Apache with or into any
       other person or entity in a transaction in which either we are not the
       sole surviving corporation or our common stock existing before the
       transaction is converted into cash, securities or other property and in
       which those exchanging our common stock do not, as a result of the
       transaction, receive either 75% or more of the survivor's common stock or
       75% or more of the voting power of the survivor's voting stock.

     We will not purchase any debt securities if there has occurred and is
continuing an event of default under either indenture, other than default in
payment of the purchase price payable for the debt securities upon change in
control. In connection with any purchase of debt securities after a change in
control, we will comply with all federal and state securities laws, including,
specifically, Rule 13e-4, if applicable, of the Securities Exchange Act, and any
related Schedule 13E-4 required to be submitted under that rule.

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     We may discharge certain obligations to holders of any series of debt
securities that have not already been delivered to the trustee for cancellation
and that:

     - have become due and payable;

     - will become due and payable within one year; or
                                        27


     - are scheduled for redemption within one year.

To discharge the obligations with respect to a series of debt securities, we
must deposit with the trustee, in trust, an amount of funds in U.S. dollars or
in the foreign currency in which those debt securities are payable sufficient to
pay the entire amount of principal of, and any premium or interest on, those
debt securities to the date of the deposit if those debt securities have become
due and payable or to the maturity of the debt securities, as the case may be.

     Unless we specify otherwise in the applicable prospectus supplement, we may
elect

     - to defease and be discharged from any and all obligations with respect to
       those debt securities, which we refer to as "legal defeasance"; or

     - with respect to any debt securities, to be released from our covenant
       obligations, as may be provided for under Section 301 of either
       indenture, which we refer to as "covenant defeasance"; or,

     - with respect to any senior debt securities, to be released from our
       obligations under the covenants described above in "The Senior Indenture
       Limits Our Ability to Incur Liens" and "The Senior Indenture Limits Our
       Ability to Engage in Sale/Leaseback Transactions," which we also refer to
       as "covenant defeasance."

     In the case of legal defeasance we will still retain some obligations in
respect of the debt securities, including our obligations:

     - to pay additional amounts, if any, upon the occurrence of certain events
       of taxation, assessment or governmental charge with respect to payments
       on the debt securities;

     - to register the transfer or exchange of the debt securities;

     - to replace temporary or mutilated, destroyed, lost or stolen debt
       securities; and

     - to maintain an office or agency with respect to the debt securities and
       to hold monies for payment in trust.

     After a covenant defeasance, any omission to comply with the obligations or
covenants that have been defeased shall not constitute a default or an event of
default with respect to the debt securities.

     To elect either legal defeasance or covenant defeasance we must deposit
with the trustee, in trust, an amount, in U.S. dollars or in the foreign
currency in which the relevant debt securities are payable at stated maturity,
or in government obligations, as defined below, or both, applicable to such debt
securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient to pay
the principal of and any premium and interest on those debt securities on their
scheduled due dates.

     In addition, we can only elect legal defeasance or covenant defeasance if,
among other things:

     - the applicable defeasance does not result in a breach or violation of, or
       constitute a default under, the applicable indenture or any other
       material agreement or instrument to which we are a party or by which we
       are bound;

     - no default or event of default with respect to the debt securities to be
       defeased shall have occurred and be continuing on the date of the
       establishment of the trust and, with respect to legal defeasance only, at
       any time during the period ending on the 91st day after the date of the
       establishment of the trust; and

     - we have delivered to the trustee an opinion of counsel to the effect that
       the holders of the debt securities will not recognize income, gain or
       loss for U.S. federal income tax purposes as a result of the defeasance
       and will be subject to U.S. federal income tax on the same amounts, in
       the same manner and at the same times as would have been the case if the
       defeasance had not occurred, and

                                        28


       the opinion of counsel, in the case of legal defeasance, must refer to
       and be based upon a letter ruling of the Internal Revenue Service
       received by us, a Revenue Ruling published by the Internal Revenue
       Service or a change in applicable U.S. federal income tax law occurring
       after the date of the applicable indenture.

     Each indenture deems a foreign currency to be any currency, currency unit
or composite currency issued by the government of one or more countries other
than the United States or by any recognized confederation or association of
governments.

     Each indenture defines government obligations as securities which are not
callable or redeemable at the option of the issuer or issuers and are:

     - direct obligations of the United States or the government or the
       governments in the confederation which issued the foreign currency in
       which the debt securities of a particular series are payable, for the
       payment of which its full faith and credit is pledged; or

     - obligations of a person or entity controlled or supervised by and acting
       as an agency or instrumentality of the United States or the government or
       governments which issued the foreign currency in which the debt
       securities of a particular series are payable, the timely payment of
       which is unconditionally guaranteed as a full faith and credit obligation
       by the United States or that other government or governments.

Government obligations also include a depositary receipt issued by a bank or
trust company as custodian with respect to any government obligation described
above or a specific payment of interest on or principal of or any other amount
with respect to any government obligation held by that custodian for the account
of the holder of such depositary receipt, as long as, except as required by law,
that custodian is not authorized to make any deduction from the amount payable
to the holder of the depositary receipt from any amount received by the
custodian with respect to the government obligation or the specific payment of
interest on or principal of or any other amount with respect to the government
obligation evidenced by the depositary receipt.

     Unless otherwise specified in the applicable prospectus supplement, if,
after we have deposited funds and/or government obligations to effect legal
defeasance or covenant defeasance with respect to debt securities of any series,
either:

     - the holder of a debt security of that series is entitled to, and does,
       elect to receive payment in a currency other than that in which such
       deposit has been made in respect of that debt security; or

     - a conversion event, as defined below, occurs in respect of the foreign
       currency in which the deposit has been made,

the indebtedness represented by that debt security shall be deemed to have been,
and will be, fully discharged and satisfied through the payment of the principal
of, and any premium and interest on, that debt security as that debt security
becomes due out of the proceeds yielded by converting the amount or other
properties so deposited in respect of that debt security into the currency in
which that debt security becomes payable as a result of the election or
conversion event based on:

     - in the case of payments made pursuant to the first of the two items in
       the list above, the applicable market exchange rate for the currency in
       effect on the second business day prior to the date of the payment; or

     - with respect to a conversion event, the applicable market exchange rate
       for such foreign currency in effect, as nearly as feasible, at the time
       of the conversion event.

                                        29


     Each indenture defines a "conversion event" as the cessation of use of:

     - a foreign currency other than the ECU or euro both by the government of
       the country or the confederation which issued such foreign currency and
       for the settlement of transactions by a central bank or other public
       institutions of or within the international banking community;

     - the ECU or euro both within the European Monetary System and for the
       settlement of transactions by public institutions of or within the
       European Monetary System; or

     - any currency unit or composite currency other than the ECU or euro for
       the purposes for which it was established.

Unless otherwise provided in the applicable prospectus supplement, all payments
of principal of, and any premium and interest on, any debt security that are
payable in a foreign currency that ceases to be used by the government or
confederation of issuance shall be made in U.S. dollars.

     If we effect a covenant defeasance with respect to any debt securities and
the debt securities are declared due and payable because of the occurrence of
any event of default other than an event of default with respect to which there
has been covenant defeasance, the amount in the foreign currency in which the
debt securities are payable, and government obligations on deposit with the
trustee, will be sufficient to pay amounts due on the debt securities at the
time of the stated maturity but may not be sufficient to pay amounts due on the
debt securities at the time of the acceleration resulting from the event of
default. However, we would remain liable for payment of the amounts due at the
time of acceleration.

     The applicable prospectus supplement may further describe the provisions,
if any, permitting defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the debt
securities of or within a particular series.

     Under each indenture, we are required to furnish to the trustee annually a
statement as to our performance of certain of our obligations under the
indenture and as to any default in such performance. We are also required to
deliver to the trustee, within five days after occurrence thereof, written
notice of any event which after notice or lapse of time or both would constitute
an event of default.

MODIFICATION AND WAIVER

     We and the trustee may, without the consent of holders, modify provisions
of each indenture for certain purposes, including, among other things, curing
ambiguities and maintaining the qualification of the applicable indenture under
the Trust Indenture Act. We and the trustee may modify certain other provisions
of each indenture with the consent of the holders of not less than two-thirds,
in the case of the senior indenture, or a majority, in the case of the
subordinate indenture, in aggregate principal amount of the debt securities of
each series issued under that indenture affected by the modification. However,
the provisions of either indenture may not be modified without the consent of
the holder of each debt security affected thereby if the modification would:

     - change the stated maturity or any installment of the principal of, or any
       premium or interest on, or any installment of principal, or any
       additional amounts with respect to, any debt security issued under that
       indenture;

     - reduce the principal amount of, or premium or interest on, or any
       additional amounts with respect to, any debt security issued under that
       indenture;

     - change the coin or currency in which any debt security issued under that
       indenture or any premium or any interest on that debt security or any
       additional amounts with respect to that debt security is payable;

     - if the debt securities are convertible or exchangeable, modify the
       conversion or exchange provision in a manner adverse to holders of that
       debt security;

                                        30


     - in the case of a subordinated debt security, modify any of the
       subordination provisions in a manner adverse to holders of that debt
       security;

     - impair the right to institute suit for the enforcement of any payment on
       or after the stated maturity of any debt securities issued under that
       indenture or, in the case of redemption, exchange or conversion, if
       applicable, on or after the redemption, exchange or conversion date or,
       in the case of repayment at the option of any holder, if applicable, on
       or after the date for repayment or in the case of a change in control,
       after the change in control purchase date;

     - reduce the percentage and principal amount of the outstanding debt
       securities, the consent of whose holders is required under that indenture
       in order to take certain actions;

     - change any of our obligations to maintain an office or agency in the
       places and for the purposes required by that indenture; or

     - modify any of the above provisions.

     The holders of at least a majority in aggregate principal amount of debt
securities of any series issued under one of the indentures may, on behalf of
the holders of all debt securities of that series, waive our compliance with
certain restrictive provisions of that indenture. The holders of not less than a
majority in aggregate principal amount of debt securities of any series issued
under one of the indentures may, on behalf of all holders of debt securities of
that series, waive any past default and its consequences under that indenture
with respect to the debt securities of that series, except:

     - a payment default with respect to debt securities of that series; or

     - a default of a covenant or provision of that indenture that cannot be
       modified or amended without the consent of the holder of the debt
       securities of that series.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     We may, without the consent of the holders of the debt securities,
consolidate or merge with or into, or convey, transfer or lease our properties
and assets substantially as an entirety to, any person that is a corporation,
limited liability company, partnership or trust organized and validly existing
under the laws of any domestic jurisdiction. We may also permit any of those
persons to consolidate with or merge into us or convey, transfer or lease its
properties and assets substantially as an entirety to us, as long as:

     - any successor person assumes our obligations on the debt securities;

     - no event of default under the applicable indenture has occurred and is
       continuing after giving effect to the transaction;

     - no event which, after notice or lapse of time or both, would become an
       event of default under the applicable indenture has occurred and is
       continuing after giving effect to the transaction; and

     - certain other conditions are met.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF TRUST PREFERRED SECURITIES

     The following applies only in the event that debt securities are held by an
Apache Trust.

     To the extent that any action under any debt securities held by an Apache
Trust is entitled to be taken by the holders of at least a specified percentage
of those debt securities, and unless otherwise specified in the applicable
prospectus supplement, holders of the trust preferred securities issued by that
Apache Trust may take action if the action is not taken by the property trustee
of that Apache Trust. Notwithstanding the foregoing, if an event of default
under those debt securities has occurred and is continuing and is attributable
either to:

     - the failure of Apache to pay the principal of, or any premium or interest
       on, those debt securities on the due date; or

                                        31


     - the failure by Apache to deliver the required securities or other
       property upon an appropriate conversion or exchange election, if any,

and an event of default has occurred and is continuing under the applicable
trust agreement, a holder of the related trust preferred securities may
institute a direct action.

     A "direct action" is a legal proceeding directly against Apache for
enforcement of payment to the holder of trust preferred securities issued by an
Apache Trust of the principal of or any premium or interest on the debt
securities held by that trust having a principal amount equal to the liquidation
amount of those trust preferred securities held by that holder or for
enforcement of any conversion or exchange rights, as the case may be. Apache may
not amend an indenture to remove this right to bring a direct action without the
prior written consent of the holders of all of the trust preferred securities
outstanding that have an interest in the related debt securities. If the right
to bring a direct action is removed, the Apache Trusts may become subject to the
reporting obligations under the Securities Exchange Act. Notwithstanding any
payments made to a holder of trust preferred securities by Apache in connection
with a direct action, Apache will remain obligated to pay the principal of, and
any premium and interest on, the related debt securities, and Apache will be
subrogated to the rights of the holders of those trust preferred securities with
respect to payments on the trust preferred securities to the extent of any
payments made by Apache to the holder in any direct action.

     The holders of the trust preferred securities will not be able to exercise
directly any remedies, other than those set forth in the preceding paragraph,
available to the holders of the related debt securities unless an event of
default has occurred and is continuing under the applicable trust agreement. See
"Description of Trust Preferred Securities -- Events of Default; Notice" below.

                   DESCRIPTION OF TRUST PREFERRED SECURITIES

     Each Apache Trust will issue under its trust agreement only one series of
trust preferred securities, which will represent beneficial interests in that
Apache Trust. Each Apache Trust will qualify its trust agreement under the Trust
Indenture Act. Each trust agreement is subject to, and governed by, the Trust
Indenture Act. This summary of certain terms and provisions of the trust
preferred securities and the trust agreement does not purport to be complete and
is subject to, and is qualified in its entirety by reference to, all of the
provisions of the trust preferred securities and the trust agreement, including
the definitions of certain terms, and those made a part of the trust agreement
by the Trust Indenture Act. A form of trust agreement is, and the terms and
conditions of trust securities and forms thereof will be, filed as exhibits to
the registration statement that includes this prospectus.

     Each Apache Trust will describe the specific terms of the trust preferred
securities it is offering in the applicable prospectus supplement, including:

     - the designation, number, purchase price and liquidation amount, if any,
       of the trust preferred securities;

     - the distribution rate, or method of calculation of the distribution rate,
       for the trust preferred securities and, if applicable, any deferral
       provisions;

     - whether the distributions on the trust preferred securities will be
       cumulative and, if so, the dates from which and upon which distributions
       will accumulate and be payable and the record dates;

     - if other than U.S. dollars, the currency in which cash payments are
       payable;

     - the liquidation amount per trust preferred security which will be paid
       out of the assets of that Apache Trust to the holders upon voluntary or
       involuntary dissolution and liquidation of that trust;

     - the obligation or right, if any, of that Apache Trust to purchase or
       redeem its trust preferred securities, whether pursuant to a sinking fund
       or otherwise, and the price or prices at which, the date or dates on
       which or period or periods within which and the terms and conditions upon
       which,

                                        32


       it will or may purchase or redeem, in whole or in part, the trust
       preferred securities pursuant to its obligation or right to purchase or
       redeem;

     - the terms and conditions, if any, upon which the trust preferred
       securities may be converted or exchanged, in addition to the
       circumstances described herein, into other securities or property, or a
       combination of the foregoing;

     - the obligation or right, if any, of Apache, that Apache Trust or any
       other party to liquidate that Apache Trust and any terms and conditions
       of such liquidation;

     - the voting rights, if any, of the holders;

     - if applicable, any securities exchange upon which the trust preferred
       securities will be listed;

     - if applicable, a description of any remarketing, auction or other similar
       arrangements;

     - whether the trust preferred securities are issuable in book-entry only
       form and, if so, the identity of the depositary and disclosure relating
       to the depositary arrangements; and

     - any other rights, preferences, privileges, limitations or restrictions of
       the trust preferred securities consistent with the trust agreement or
       with applicable law, which may differ from those described herein.

     Each Apache Trust will also describe certain material United States federal
income tax considerations applicable to any offering of trust preferred
securities in the applicable prospectus supplement.

     If indicated in the applicable prospectus supplement, the terms of an
Apache Trust may differ from the terms summarized below.

GENERAL

     The trust preferred securities of each Apache Trust will rank equally, and
payments will be made on the trust preferred securities proportionately, with
the trust common securities of each Apache Trust except as described under
"-- Subordination of Trust Common Securities." Apache Trust will use the
proceeds from the sale of trust preferred securities and trust common securities
to purchase an aggregate principal amount of debt securities of Apache equal to
the aggregate liquidation amount of those trust preferred securities and trust
common securities. The property trustee of each Apache Trust will hold legal
title to the debt securities for the benefit of the holders of the related trust
securities. In addition, Apache will execute a guarantee for the benefit of the
holders of the related trust preferred securities. The guarantees will not
guarantee payment of distributions or amounts payable or securities or other
property deliverable, if any, on redemption, repayment, conversion or exchange
of the trust preferred securities or liquidation of an Apache Trust when the
trust does not have funds or other property legally available for payment or
delivery. See "Description of Trust Preferred Securities Guarantees."

     The revenue of an Apache Trust available for distribution to holders of its
trust preferred securities will be limited to payments under the related debt
securities and any other assets held by that Apache Trust. If Apache fails to
make a required payment in respect of those debt securities or any other assets,
that Apache Trust will not have sufficient funds to make the related payments,
including distributions, in respect of its trust preferred securities.

SUBORDINATION OF TRUST COMMON SECURITIES

     Each Apache Trust will pay distributions on, and the applicable redemption
price of, and any other amounts payable or property deliverable under, the trust
securities it issues equally among its trust preferred securities and its trust
common securities based on their respective liquidation amounts; provided,
however, that if on any distribution date, redemption date, repayment date or
conversion or exchange date, or upon liquidation or an event of default under
the debt securities held by that Apache Trust or any other event of default
under the trust agreement has occurred and is continuing, that Apache Trust will
not pay any distribution on, or applicable redemption or repayment price of, or
convert or exchange any of its trust
                                        33


common securities, and will not make any other payment on account of the
redemption, repayment, conversion, exchange, liquidation or other acquisition of
the trust common securities, unless payment in full in cash of all accumulated
distributions on all of the outstanding trust preferred securities of that
Apache Trust for all distribution periods terminating on or before the
redemption, repayment, conversion, exchange, liquidation or other acquisition,
and, in the case of payment of the applicable redemption or repayment price, the
full amount of the redemption or repayment price, will have been made or
provided for and, in the case of conversion or exchange, that the trust
preferred securities have been converted or exchanged in full and other amounts
payable have been paid. The property trustee will apply all available funds
first to the payment in full in cash of all distributions on, or the applicable
redemption price of, the trust preferred securities issued by that Apache Trust
then due and payable.

     Until any event of default under the trust agreement for an Apache Trust
has been cured, waived or otherwise eliminated, the property trustee will act
solely on behalf of the holders of the trust preferred securities of that Apache
Trust and not on behalf of Apache as the direct or indirect trust common
securities owner, and only the holders of the trust preferred securities issued
by that Apache Trust will have the right to direct the property trustee to act
on their behalf.

EVENTS OF DEFAULT; NOTICE

     The occurrence of an event of default under the debt securities and any
other assets held by an Apache Trust will constitute an event of default under
the trust agreement for that Apache Trust. Within 90 business days after the
occurrence of an event of default actually known to the property trustee, the
property trustee will transmit notice of that event of default to the holders of
the trust preferred securities of that Apache Trust, the administrative trustees
and Apache, as sponsor, unless the event of default shall have been cured or
waived.

     For a discussion of the limited circumstances in which holders of trust
preferred securities may bring a direct action against Apache under the debt
securities, see "Description Of Debt Securities -- Enforcement of Certain Rights
by Holders of Trust Preferred Securities." The applicable prospectus supplement
may describe additional events of default under the trust agreement.

REMOVAL OF TRUSTEES

     Unless an event of default under the debt securities held by an Apache
Trust has occurred and is continuing, Apache, as the direct or indirect owner of
trust common securities of that Apache Trust, may remove the property trustee,
the Delaware trustee and the administrative trustees at any time. If an event of
default under the debt securities held by an Apache Trust has occurred and is
continuing, only the holders of a majority in liquidation amount of the
outstanding trust preferred securities of that Apache Trust may remove and
replace the property trustee and the Delaware trustee for that Apache Trust. In
no event will the holders of the trust preferred securities have the right to
vote to appoint, remove or replace the administrative trustees, which voting
rights are vested exclusively in Apache as the direct or indirect trust common
securities owner. No resignation or removal of a property or Delaware trustee,
and no appointment of a successor to that trustee, will be effective until the
acceptance of appointment by the successor trustee in accordance with the
provisions of the applicable trust agreement.

MERGER OR CONSOLIDATION OF PROPERTY OR DELAWARE TRUSTEES

     Any person into which the property trustee or the Delaware trustee may be
merged or converted or with which it may be consolidated, or any person
resulting from any merger, conversion or consolidation to which the property
trustee or the Delaware trustee will be a party, or any person succeeding to all
or substantially all the corporate trust business of the property trustee or the
Delaware trustee, will be the successor of the property trustee or the Delaware
trustee under the trust agreement, provided that the person will be otherwise
qualified and eligible.

                                        34


MERGERS, CONVERSIONS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF AN APACHE
TRUST

     An Apache Trust may not merge with or into, convert into, consolidate,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets as an entirety or substantially as an entirety, to any other person,
except as described below or as otherwise described in the applicable prospectus
supplement. An Apache Trust may, at the request of Apache, as sponsor, with the
consent of the administrative trustees but without the consent of the holders of
its trust preferred securities, the Delaware trustee or the property trustee,
merge with or into, convert into, consolidate, amalgamate, or be replaced by a
trust organized as such under the laws of any state of the United States;
provided, that:

     - the successor entity expressly assumes all of the obligations of that
       Apache Trust under any agreement to which the trust is a party and
       either:

        - expressly assumes all of the obligations of that Apache Trust with
          respect to the trust securities of that Apache Trust, or

        - substitutes for the trust securities of that Apache Trust other
          securities having substantially the same terms as those trust
          securities, so long as the successor trust securities rank the same as
          the trust securities rank with respect to distributions and payments
          upon liquidation, redemption and otherwise;

     - the successor entity has a trustee possessing substantially the same
       powers and duties as the property trustee;

     - the successor securities are listed, or any successor securities will be
       listed upon notification of issuance, if applicable, on each national
       securities exchange or other organization on which the trust securities
       of that Apache Trust are then listed, if any;

     - the merger, conversion, consolidation, amalgamation or replacement does
       not cause the trust securities, including any successor securities, of
       that Apache Trust to be downgraded or placed under surveillance or review
       by any nationally recognized statistical rating organization;

     - the merger, conversion, consolidation, amalgamation or replacement does
       not adversely affect the rights, preferences and privileges of the
       holders of the trust securities, including any successor securities, of
       that Apache Trust in any material respect;

     - the successor entity has a purpose substantially identical to that of
       that Apache Trust;

     - prior to the merger, conversion, consolidation, amalgamation or
       replacement, Apache has received an opinion from nationally recognized
       independent counsel to that Apache Trust experienced in these matters to
       the effect that

        - the merger, conversion, consolidation, amalgamation or replacement
          does not adversely affect the rights, preferences and privileges of
          the holders of the trust securities, including any successor
          securities, of that Apache Trust in any material respect,

        - following the merger, conversion, consolidation, amalgamation or
          replacement, neither that Apache Trust nor the successor entity, if
          any, will be required to register as an investment company under the
          Investment Company Act of 1940, as amended, and

        - following the merger, conversion, consolidation, amalgamation or
          replacement, that Apache Trust or the successor entity, as the case
          may be, will continue to be classified as a grantor trust for United
          States federal income tax purposes;

     - Apache or any permitted successor or assignee directly or indirectly owns
       all of the common securities of the successor entity and guarantees the
       obligations of the successor entity under the successor securities at
       least to the extent provided by the applicable guarantee; and

                                        35


     - the property trustee has received our officer's certificate and an
       opinion of counsel, each to the effect that all conditions precedent to
       the transaction as set forth in the trust agreement have been satisfied.

VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT

     Except as provided under "-- Mergers, Conversions, Consolidations,
Amalgamations or Replacements of an Apache Trust" and "Description of Trust
Preferred Securities Guarantees -- Amendments and Assignment" and as otherwise
required by law and the trust agreement or specified in the applicable
prospectus supplement, the holders of trust preferred securities will have no
voting rights.

     Apache, the property trustee, the Delaware trustee and the administrative
trustees may amend from time to time the trust agreement for an Apache Trust,
without the consent of the holders of the trust securities of that Apache Trust,

     - to cure any ambiguity, or correct or supplement any provisions in the
       trust agreement that may be defective or inconsistent with any other
       provision,

     - to add to the covenants, restrictions or obligations of the sponsor,

     - to conform to any change in the Investment Company Act or Trust Indenture
       Act or the rules promulgated thereunder, or any written change in
       interpretation of such acts or rules by any governmental authority, or

     - to cause that Apache Trust to continue to be classified for United States
       federal income tax purposes as a grantor trust;

provided, however, that in the case of the first bullet point above, the
modification will not adversely affect in any material respect the interests of
the holders of the trust securities issued by that Apache Trust.

     Without the consent of each holder of trust securities issued by an Apache
Trust, the trust agreement for that Apache Trust may not be amended to:

     - change the distribution rate, or manner of calculation of the
       distribution rate, amount, timing or currency or otherwise adversely
       affect the method of any required payment;

     - change its purpose;

     - authorize the issuance of any additional beneficial interests;

     - change the conversion, exchange or redemption provisions, if any;

     - change the conditions precedent for Apache to elect to dissolve that
       Apache Trust and distribute the debt securities held by that Apache Trust
       to the holders of the trust securities, if applicable;

     - change the liquidation, distribution or other provisions relating to the
       distribution of amounts payable upon the dissolution and liquidation of
       that Apache Trust;

     - affect the limited liability of any holder of its trust securities; or

     - restrict the right of a holder of its trust securities to institute suit
       for the enforcement of any required distribution on or, if applicable,
       after the due date therefor or for the conversion or exchange of the
       trust securities in accordance with their terms.

     So long as the property trustee holds any debt securities for an Apache
Trust, the property trustee, the Delaware trustee and the administrative
trustees for that Apache Trust will not:

     - direct the time, method and place of conducting any proceeding for any
       remedy available to the debt securities trustee, or execute any trust or
       power conferred on the property trustee, with respect to those debt
       securities;

     - waive certain past defaults under the applicable indenture;

     - exercise any right to rescind or annul a declaration of acceleration of
       the maturity of the principal of those debt securities; or

                                        36


     - consent to any amendment, modification or termination of the applicable
       indenture or those debt securities, where consent is required.

without, in each case, obtaining the prior approval of the holders of a majority
in liquidation amount of all outstanding trust preferred securities of that
Apache Trust; provided, however, that where a consent under the applicable
indenture would require the consent of each holder of those debt securities
affected thereby, the property trustee will not consent without the prior
approval of each holder of the trust preferred securities issued by that Apache
Trust. The property trustee, the Delaware trustee and the administrative
trustees may not revoke any action previously authorized or approved by a vote
of the holders of trust preferred securities except by subsequent vote of the
holders. The property trustee will notify each holder of trust preferred
securities of any notice of default with respect to the applicable debt
securities. In addition to obtaining approvals of holders of trust preferred
securities referred to above, prior to taking any of the foregoing actions, the
property trustee, the Delaware trustee and the administrative trustees will
obtain an opinion of counsel experienced in these matters to the effect that the
applicable Apache Trust will not be classified as other than a grantor trust for
United States federal income tax purposes on account of such action.

     Any required approval of holders of trust preferred securities may be given
at a meeting of the holders convened for this purpose or by written consent
without prior notice. The property trustee will cause a notice of any meeting at
which holders of trust preferred securities are entitled to vote to be given to
each holder of record of trust preferred securities in the manner set forth in
the trust agreement.

     Notwithstanding that holders of trust preferred securities are entitled to
vote or consent under any of the circumstances referred to above, any trust
preferred securities that are owned by Apache or any affiliate of Apache will,
for purposes of this vote or consent, be treated as if they were not
outstanding.

GLOBAL TRUST PREFERRED SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, trust
preferred securities will be represented by one or more global certificates
deposited with, or on behalf of, DTC, or other depository identified in the
prospectus supplement, or a nominee of DTC or other depository, in each case for
credit to an account of a participant in DTC or other depository. The identity
of the depository and the specific terms of the depositary arrangements with
respect to the trust preferred securities to be represented by one or more
global certificates to the extent not discussed under "Book-Entry Securities"
will be described in the applicable prospectus supplement. However, unless
otherwise specified in the applicable prospectus supplement, DTC will be the
depositary and the depository arrangements described with respect to the debt
securities will apply to those trust preferred securities as well, except all
references to Apache shall include Apache Trust I and Apache Trust II and all
references to the indentures will refer to the applicable trust agreement. See
"Description of Debt Securities -- Global Securities" and "Book-Entry
Securities."

PAYMENT AND PAYING AGENT

     Payments in respect of any global certificate representing trust preferred
securities will be made to Cede & Co. as nominee of DTC or other applicable
depository or its nominee, which will credit the relevant accounts at DTC or
other depository on the applicable payment dates, while payments in respect of
trust preferred securities in certificated form will be made by check mailed to
the address of the holder entitled thereto as the address will appear on the
register. The paying agent will initially be the property trustee and any
co-paying agent chosen by the property trustee and acceptable to the
administrative trustees and Apache. The paying agent will be permitted to resign
as paying agent upon 30 days prior written notice to the property trustee, the
administrative trustees and Apache. In the event that the property trustee will
no longer be the paying agent, the administrative trustees will appoint a
successor, which will be a bank or trust company acceptable to the
administrative trustees and Apache, to act as paying agent.

                                        37


REGISTRAR AND TRANSFER AGENT

     The property trustee will act as registrar and transfer agent for the trust
preferred securities.

     Registration of transfers of trust preferred securities will be effected
without charge by or on behalf of an Apache Trust, upon payment of any tax or
other governmental charges that may be imposed in connection with any transfer
or exchange. An Apache Trust will not be required to register or cause to be
registered the transfer of its trust preferred securities after they have been
converted, exchanged, redeemed, repaid or called for redemption or repayment.

INFORMATION CONCERNING THE PROPERTY TRUSTEE

     The property trustee, other than during the occurrence and continuance of
an event of default under the trust agreement, will undertake to perform only
the duties that are specifically set forth in the trust agreement and, during
the continuance of that event of default, must exercise the same degree of care
and skill as a prudent person would exercise or use in the conduct of his or her
own affairs. Subject to the foregoing, the property trustee will not be under
any obligation to exercise any of the powers vested in it by the trust agreement
at the request of any holder of the related trust securities unless the holder
offers the property trustee reasonable indemnity against the costs, expenses and
liabilities that it might incur thereby.

MISCELLANEOUS

     The administrative trustees are authorized and directed to conduct the
affairs of and to operate each Apache Trust in such a way that:

     - that Apache Trust will not be deemed to be an investment company required
       to be registered under the Investment Company Act;

     - that Apache Trust will be classified as a grantor trust for United States
       federal income tax purposes; and

     - the debt securities held by that Apache Trust will be treated as
       indebtedness of Apache for United States federal income tax purposes.

Apache and the administrative trustees are authorized to take any action, not
inconsistent with applicable law, the certificate of trust of each Apache Trust
or each trust agreement, that the administrative trustees determine in their
discretion to be necessary or desirable for those purposes, as long as that
action does not materially adversely affect the interests of the holders of the
related trust securities.

     Holders of trust preferred securities will not have any preemptive or
similar rights.

              DESCRIPTION OF TRUST PREFERRED SECURITIES GUARANTEES

     Apache will execute and deliver a guarantee concurrently with the issuance
by an Apache Trust of its trust preferred securities for the benefit of the
holders from time to time of those trust preferred securities. That guarantee
will be held for those holders by a guarantee trustee. Apache will qualify each
of the guarantees as an indenture under the Trust Indenture Act. The guarantees
will be subject to, and governed by, the Trust Indenture Act. This summary of
certain terms and provisions of a guarantee does not purport to be complete and
is subject to, and qualified in its entirety by reference to, all of the
provisions of each guarantee, including the definitions of terms, and those made
a part of each guarantee by the Trust Indenture Act. A form of guarantee is
filed as an exhibit to the registration statement that includes this prospectus.
If indicated in the applicable prospectus supplement, the terms of a particular
guarantee may differ from the terms discussed below.

                                        38


GENERAL

     Apache will irrevocably agree to pay in full, to the extent set forth
herein, the guarantee payments to the holders of the related trust preferred
securities, as and when due, regardless of any defense, right of set-off or
counterclaim that an Apache Trust may have or assert. The following payments
constitute guarantee payments with respect to trust preferred securities and, to
the extent not paid by or on behalf of an Apache Trust, will be subject to the
applicable guarantee:

     - any accrued and unpaid distributions required to be paid on the
       applicable trust preferred securities, to the extent that an Apache Trust
       has funds legally available therefor at such time;

     - the applicable redemption or repayment price and all accrued and unpaid
       distributions to the date of redemption or repayment with respect to the
       applicable trust preferred securities called for redemption or repayment,
       to the extent that an Apache Trust has funds legally available therefor
       at such time; or

     - upon a voluntary or involuntary dissolution and liquidation of the
       applicable Apache Trust, other than in connection with the distribution
       of the debt securities to holders of its trust preferred securities or
       the redemption, repayment, conversion or exchange of its trust preferred
       securities, if applicable, the lesser of

          - the amounts due upon the dissolution and liquidation of that Apache
            Trust, to the extent that it has funds legally available therefor at
            the time, and

          - the amount of assets of that Apache Trust remaining available for
            distribution to holders of its trust preferred securities after
            satisfaction of liabilities to its creditors as required by
            applicable law.

     Apache's obligation to make a guarantee payment may be satisfied by direct
payment of the required amounts by Apache to the holders of the applicable trust
preferred securities entitled to those payments or by causing the applicable
Apache Trust to pay those amounts to the holders.

     If the trust preferred securities are exchangeable or convertible into
other securities, Apache will also irrevocably agree to cause the applicable
Apache Trust to deliver to holders of those trust preferred securities those
other securities in accordance with the applicable exchange or conversion
provisions.

     Apache will, through the guarantee, the applicable trust agreement, the
related debt securities and the applicable indenture, taken together, fully,
irrevocably and unconditionally guarantee all of each Apache Trust's obligations
under its trust preferred securities. No single document standing alone or
operating in conjunction with fewer than all of the other documents constitutes
a guarantee. It is only the combined operation of these documents that has the
effect of providing a full, irrevocable and unconditional guarantee of each
Apache Trust's obligations under its trust preferred securities.

RANKING

     Unless otherwise specified in the applicable prospectus supplement, each
guarantee will constitute an unsecured obligation of Apache and will rank equal
to the debt securities held by the Apache Trust that issued the preferred trust
securities covered by the guarantee. Each trust agreement provides that each
holder of trust preferred securities, by acceptance of the applicable trust
preferred securities, agrees to the terms of the related guarantee, including
any subordination provisions.

     The guarantees will not limit the amount of secured or unsecured debt,
including indebtedness under the indentures, that may be incurred by Apache or
any of its subsidiaries.

GUARANTEE OF PAYMENT

     Each guarantee will constitute a guarantee of payment and not of
collection. This means that the guaranteed party may institute a legal
proceeding directly against Apache to enforce its rights under a guarantee
without first instituting a legal proceeding against any other person or entity.
A guarantee will
                                        39


not be discharged except by payment of the related guarantee payments in full to
the extent not paid by the applicable Apache Trust or upon distribution of the
debt securities or other assets held by the Apache Trust to the holders of the
its trust preferred securities.

AMENDMENTS AND ASSIGNMENT

     Except with respect to any changes that do not materially adversely affect
the rights of holders of the related trust preferred securities, in which case
no approval will be required, a guarantee may not be amended without the prior
approval of the holders of a majority of the liquidation amount of the
outstanding trust preferred securities covered by that guarantee. The manner of
obtaining any approval will be as set forth under "Description Of Trust
Preferred Securities -- Voting Rights; Amendment of a Trust Agreement." All
guarantees and agreements contained in a guarantee will bind the successors,
assigns, receivers, trustees and representatives of Apache and will inure to the
benefit of the holders of the related trust preferred securities then
outstanding.

EVENTS OF DEFAULT

     An event of default under a guarantee will occur upon the failure of Apache
to perform any of its payment or other obligations under that guarantee,
provided that, except with respect to a default in respect of any guarantee
payment or delivery of any securities upon conversion or exchange of the trust
securities, Apache has not cured the default 90 days from the date the guarantee
trustee obtains knowledge of the event of default. The holders of a majority in
liquidation amount of the trust preferred securities covered by a guarantee will
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the guarantee trustee in respect of that guarantee
or to direct the exercise of any trust or power conferred upon the guarantee
trustee under that guarantee.

     If the guarantee trustee fails to enforce a guarantee, any holder of the
related trust preferred securities may institute a legal proceeding directly
against Apache to enforce its rights under that guarantee without first
instituting a legal proceeding against the applicable Apache Trust, the
guarantee trustee or any other person or entity.

TERMINATION

     A guarantee will terminate and be of no further force and effect upon full
payment of the applicable redemption or repayment price of the related trust
preferred securities, upon full payment of all amounts or delivery of all
securities or other property due upon the dissolution and liquidation of the
applicable Apache Trust or upon the conversion or exchange of all of the related
trust preferred securities. A guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of the related trust
preferred securities must restore payment of any sums paid or other property
distributed under those trust preferred securities or the related guarantee.

GOVERNING LAW

     The guarantees will be governed by and construed in accordance with the
laws of the State of New York.

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

     The guarantee trustee, other than during the occurrence and continuance of
a default by Apache in performance of a guarantee, will undertake to perform
only the duties that are specifically set forth in that guarantee and, during
the continuance of that default, must exercise the same degree of care and skill
as a prudent person would exercise or use in the conduct of his or her own
affairs. Subject to the foregoing, the guarantee trustee will not be under any
obligation to exercise any of the powers vested in it by a guarantee at the
request of any holder of the related trust preferred securities unless it is
offered reasonable indemnity against the costs, expenses and liabilities that it
might incur.

                                        40


RIGHTS UPON DISSOLUTION

     Unless the debt securities held by an Apache Trust are distributed to
holders of the related trust preferred securities, upon any voluntary or
involuntary dissolution and liquidation of that Apache Trust, after satisfaction
of the liabilities of its creditors as required by applicable law, the holders
of those trust securities will be entitled to receive, out of assets held by
that Apache Trust, the liquidation distribution in cash. Upon any voluntary or
involuntary liquidation or bankruptcy of Apache, the property trustee, as holder
of the debt securities, would be a creditor of Apache.

            DESCRIPTION OF COMMON STOCK PURCHASE CONTRACTS AND UNITS

     We may issue stock purchase contracts, representing contracts entitling or
obligating holders to purchase from Apache, and Apache to sell to the holders, a
specified number of shares of common stock at a future date or dates. The price
per share of common stock may be fixed at the time the contracts are issued or
may be determined by reference to a specific formula set forth in the contracts.
The common stock purchase contracts may be issued separately or as a part of
units, which are referred to in this prospectus as "common stock purchase
units," consisting of a common stock purchase contract and, as security for the
holder's obligations to purchase the common stock under the contracts, the
following:

     - senior debt securities or subordinated debt securities of Apache;

     - preferred stock of Apache;

     - debt obligations of third parties, including U.S. Treasury securities;

     - trust preferred securities of an Apache Trust;

     - any other security described in the applicable prospectus supplement; or

     - any combination of the foregoing.

     The common stock purchase contracts may require Apache to make periodic
payments to the holders of the common stock purchase units or vice versa, and
such payments may be unsecured or prefunded on some basis. The common stock
purchase contracts may require holders to secure their obligations thereunder in
a specified manner, and in certain circumstances Apache may deliver newly issued
prepaid common stock purchase contracts, which are referred to as "prepaid
securities," upon release to a holder of any collateral securing such holder's
obligations under the original contract.

     The applicable prospectus supplement will describe the terms of any common
stock purchase contracts or units and, if applicable, prepaid securities. The
description in the prospectus supplement will not purport to be complete and
will be qualified in its entirety by reference to the contracts, the collateral
arrangements and depositary arrangements, if applicable, relating to such
contracts or units and, if applicable, the prepaid securities and the document
pursuant to which such prepaid securities will be issued.

                             BOOK-ENTRY SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, we will
issue to investors securities, other than our common stock, in the form of one
or more book-entry certificates registered in the name of a depository or a
nominee of a depository. Unless otherwise specified in the applicable prospectus
supplement, the depository will be The Depository Trust Company, also referred
to as DTC. We have been informed by DTC that its nominee will be Cede & Co.
Accordingly, Cede is expected to be the initial registered holder of all
securities that are issued in book-entry form.

     No person that acquires a beneficial interest in securities issued in
book-entry form will be entitled to receive a certificate representing those
securities, except as set forth in this prospectus or in the applicable
prospectus supplement. Unless and until definitive securities are issued under
the limited circumstances

                                        41


described below, all references to actions by holders or beneficial owners of
securities issued in book-entry form will refer to actions taken by DTC upon
instructions from its participants, and all references to payments and notices
to holders or beneficial owners will refer to payments and notices to DTC or
Cede, as the registered holder of such securities.

     DTC has informed us that it is:

     - a limited-purpose trust company organized under New York banking laws;

     - a "banking organization" within the meaning of the New York banking laws;

     - a member of the Federal Reserve System;

     - a "clearing corporation" within the meaning of the New York Uniform
       Commercial Code; and

     - a "clearing agency" registered under the Securities Exchange Act.

     DTC has also informed us that it was created to:

     - hold securities for "participants"; and

     - facilitate the computerized settlement of securities transactions among
       participants through computerized electronic book-entry changes in
       participants' accounts, thereby eliminating the need for the physical
       movement of securities certificates.

     Participants have accounts with DTC and include securities brokers and
dealers, banks, trust companies and clearing corporations. Indirect access to
the DTC system also is available to indirect participants such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

     Persons that are not participants or indirect participants but desire to
buy, sell or otherwise transfer ownership of or interests in securities may do
so only through participants and indirect participants. Under the book-entry
system, beneficial owners may experience some delay in receiving payments, as
payments will be forwarded by our agent to Cede, as nominee for DTC. DTC will
forward these payments to its participants, which thereafter will forward them
to indirect participants or beneficial owners. Beneficial owners will not be
recognized by the applicable registrar, transfer agent, trustee or depositary as
registered holders of the securities entitled to the benefits of the
certificate, the indenture or any deposit agreement. Beneficial owners that are
not participants will be permitted to exercise their rights as an owner only
indirectly through participants and, if applicable, indirect participants.

     Under the current rules and regulations affecting DTC, DTC will be required
to make book-entry transfers of securities among participants and to receive and
transmit payments to participants. Participants and indirect participants with
which beneficial owners of securities have accounts are also required by these
rules to make book-entry transfers and receive and transmit such payments on
behalf of their respective account holders.

     Because DTC can act only on behalf of participants, who in turn act only on
behalf of other participants or indirect participants, and on behalf of certain
banks, trust companies and other persons approved by it, the ability of a
beneficial owner of securities issued in book-entry form to pledge those
securities to persons or entities that do not participate in the DTC system may
be limited due to the unavailability of physical certificates for the
securities.

     DTC has advised us that it will take any action permitted to be taken by a
registered holder of any securities under the certificate, the indenture or any
deposit agreement only at the direction of one or more participants to whose
accounts with DTC the securities are credited.

     According to DTC, the information with respect to DTC has been provided to
its participants and other members of the financial community for informational
purposes only and is not intended to serve as a representation, warranty, or
contract modification of any kind.

                                        42


     Unless otherwise specified in the applicable prospectus supplement, a
book-entry security will be exchangeable for definitive securities registered in
the names of persons other than DTC or its nominee only if:

     - DTC notifies us that it is unwilling or unable to continue as depositary
       for the book-entry security or DTC ceases to be a clearing agency
       registered under the Securities Exchange Act at a time when DTC is
       required to be so registered; or

     - we execute and deliver to the applicable registrar, transfer agent,
       trustee and/or depositary an order complying with the requirements of the
       certificate, the indenture or any deposit agreement that the book-entry
       security will be so exchangeable.

     Any book-entry security that is exchangeable in accordance with the
preceding sentence will be exchangeable for securities registered in such names
as DTC directs.

     If one of the events described in the immediately preceding paragraph
occurs, DTC is generally required to notify all participants of the availability
through DTC of definitive securities. Upon surrender by DTC of the book-entry
security representing the securities and delivery of instructions for
re-registration, the registrar, transfer agent, trustee or depositary, as the
case may be, will reissue the securities as definitive securities. After
reissuance of the securities, such persons will recognize the beneficial owners
of such definitive securities as registered holders of securities.

     Except as described above:

     - a book-entry security may not be transferred except as a whole book-entry
       security by or among DTC, a nominee of DTC and/or a successor depository
       appointed by us; and

     - DTC may not sell, assign or otherwise transfer any beneficial interest in
       a book-entry security unless the beneficial interest is in an amount
       equal to an authorized denomination for the securities evidenced by the
       book-entry security.

     None of Apache, the Apache Trusts, the trustees, any registrar and transfer
agent or any depositary, or any agent of any of them, will have any
responsibility or liability for any aspect of DTC's or any participant's records
relating to, or for payments made on account of, beneficial interests in a
book-entry security.

                              PLAN OF DISTRIBUTION

     Apache and the Apache Trusts may sell the securities through agents,
underwriters or dealers, or directly to one or more purchasers without using
underwriters or agents.

     Apache and the Apache Trusts may designate agents who agree to use their
reasonable efforts to solicit purchases for the period of their appointment or
to sell securities on a continuing basis.

     If Apache and/or an Apache Trust use underwriters for a sale of securities,
the underwriters will acquire the securities for their own account. The
underwriters may resell the securities in one or more transactions, including
negotiated transactions, at a fixed public offering price or at varying prices
determined at the time of sale. The obligations of the underwriters to purchase
the securities will be subject to the conditions set forth in the applicable
underwriting agreement. The underwriters will be obligated to purchase all the
securities offered if any of those securities are purchased. Any initial public
offering price and any discounts or concessions allowed or re-allowed or paid to
dealers will be described in the applicable prospectus supplement and may be
changed from time to time.

     Underwriters, dealers and agents that participate in the distribution of
the securities may be underwriters as defined in the Securities Act and any
discounts or commissions they receive from Apache and/or an Apache Trust and any
profit on their resale of the securities may be treated as underwriting
discounts and commissions under the Securities Act. The applicable prospectus
supplement will identify

                                        43


any underwriters, dealers or agents and will describe their compensation. Apache
and the Apache Trusts may have agreements with the underwriters, dealers and
agents to indemnify them against certain civil liabilities, including
liabilities under the Securities Act. Underwriters, dealers and agents may
engage in transactions with or perform services for us or our subsidiaries in
the ordinary course of their businesses.

TRADING MARKETS AND LISTING OF SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, each
class or series of securities will be a new issue with no established trading
market, other than the common stock, which is listed on the New York Stock
Exchange and the Chicago Stock Exchange. Apache and the Apache Trusts may elect
to list any other class or series of securities on any exchange but are not
obligated to do so. It is possible that one or more underwriters may make a
market in a class or series of securities, but the underwriters will not be
obligated to do so and may discontinue any market making at any time without
notice. Neither Apache nor the Apache Trusts can give any assurance as to the
liquidity of the trading market for any of the securities.

STABILIZATION ACTIVITIES

     Any underwriter may engage in over-allotment, stabilizing transactions,
short-covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act. Over-allotment involves sales in excess of
the offering size, which create a short position. Stabilizing transactions
permit bids to purchase the underlying security so long as the stabilizing bids
do not exceed a specified maximum. Short-covering transactions involve purchases
of the securities in the open market after the distribution is completed to
cover short positions. Penalty bids permit the underwriters to reclaim a selling
concession from a dealer when the securities originally sold by the dealer are
purchased in a covering transaction to cover short positions. Those activities
may cause the price of the securities to be higher than it would otherwise be.
If commenced, the underwriters may discontinue any of the activities at any
time.

                                 LEGAL MATTERS

     The legality of the securities issued by Apache will be passed upon for
Apache by its Vice President and General Counsel, Z. S. Kobiashvili, or its
Attorney and Assistant Secretary, Jeffrey B. King. As of the date of this
prospectus, Mr. Kobiashvili holds employee stock options to purchase 56,550
shares of Apache common stock, of which options to purchase 30,125 shares are
currently exercisable, and he holds 1,522 units in Apache's Deferred Delivery
Plan, each equivalent to one share of Apache common stock. As of the date of
this prospectus, Mr. King owns 52 shares of Apache common stock through Apache's
401(k) savings plan and holds employee stock options to purchase 3,950 shares of
Apache common stock, of which options to purchase 487 shares are currently
exercisable. In addition, other customary legal matters relating to the offering
of the securities issued by Apache, including matters relating to our due
incorporation, legal existence and authorized capitalization, will be passed
upon for Apache by Mr. Kobiashvili, Mr. King or Mayor, Day, Caldwell & Keeton,
L.L.P., Houston, Texas. The legality of the securities issued by the Apache
Trusts and certain matters of Delaware law will be passed upon for the Apache
Trusts by Richards, Layton & Finger, P.A., special Delaware counsel to the
Apache Trusts. Unless otherwise specified in the accompanying prospectus

                               APACHE CORPORATION

     Apache Corporation is a Delaware corporation formed in 1954. We are an
independent energy company that explores for, develops and produces natural gas,
crude oil and natural gas liquids. In North America, our exploration and
production interests are focused on the Gulf of Mexico, the Anadarko Basin, the
Permian Basin, the Gulf Coast and the Western Sedimentary Basin of Canada.
Outside of North America, we have exploration and production interests offshore
Western Australia, in Egypt and offshore the Ivory Coast, and exploration
interests in Poland and offshore The People's Republic of China.

     We hold interests in many of our U.S., Canadian and international
properties through operating subsidiaries, such as Apache Canada Ltd., DEK
Energy Company, which was formerly known as DEKALB Energy Company, Apache Energy
Limited, which was formerly known as Hadson Energy Limited, Apache
International, Inc., and Apache Overseas, Inc. The properties referred to in
this prospectus, in any prospectus supplement or in any other document
incorporated by reference in this prospectus may be held by our subsidiaries. We
treat all operations as one line of business.

                    RATIOS OF EARNINGS TO FIXED CHARGES AND
                  RATIOS OF EARNINGS TO COMBINED FIXED CHARGES
                         AND PREFERRED STOCK DIVIDENDS

     Our ratios of earnings to fixed charges and our ratios of earnings to
combined fixed charges and preferred stock dividends were the same for each of
the periods indicated in the table below. This is because there were no shares
of preferred stock outstanding prior to 1998, and because our 1998 earnings were
inadequate to cover fixed charges and dividends as described below.



    YEAR ENDED DECEMBER 31,
--------------------------------
1998   1997   1996   1995   1994
----   ----   ----   ----   ----
                
 --    2.93   2.72   1.15   2.34


     Our ratios of earnings to fixed charges and our ratios of earnings to
combined fixed charges and preferred stock dividends were computed based on:

- "earnings," which consist of consolidated income or losses from continuing
  operations plus income taxes and fixed charges, except capitalized interest,
  or, in the case of our ratios of earnings to combined fixed charges and
  preferred stock dividends, those earnings plus preferred stock dividends; and

- "fixed charges," which consist of consolidated interest on indebtedness,
  including capitalized interest, amortization of debt discount and expense, and
  the estimated portion of rental expense attributable to interest, or, in the
  case of our ratios of earnings to combined fixed charges and preferred stock
  dividends, those fixed charges plus preferred stock dividends.

     Due to the $243.2 million non-cash write-down of the carrying value of our
U.S. proved oil and gas properties, for the year ended

                                        2


December 31, 1998, our 1998 earnings were inadequate to cover fixed charges by
$236.8 million and inadequate to cover combined fixed charges and preferred
stock dividends by $239.7 million.

     On May 17, 1995, Apache acquired DEKALB Energy Company, which is now known
as DEK Energy Company, through a merger which resulted in DEKALB becoming a
wholly-owned subsidiary of Apache. The merger was accounted for as a "pooling of
interests." As a result, our financial information for all preceding periods was
restated.

                                USE OF PROCEEDS

     Unless otherwise indicated in an accompanying prospectus supplement, we
expect to use the net proceeds from the sale of the securities for general
corporate purposes, which may include, among other things:

- the repayment of outstanding indebtedness;

- working capital;

- capital expenditures; and

- acquisitions.

     The precise amount and timing of the application of such proceeds will
depend upon our funding requirements and the availability and cost of other
funds.

                          THE SECURITIES WE MAY OFFER

     The descriptions of the securities contained in this prospectus, together
with the applicable prospectus supplements, summarize all the material terms and
provisions of the various types of securities that we may offer. The particular
terms of the securities offered by any prospectus supplement will be described
in that prospectus supplement. If indicated in the applicable prospectus
supplement, the terms of the securities may differ from the terms summarized
below. The prospectus supplement will also contain information, where
applicable, about material U.S. federal income tax considerations relating to
the securities, and the securities exchange, if any, on which the securities
will be listed.

     We may sell from time to time, in one or more offerings:

- common stock and related rights;

- preferred stock;

- depositary shares; and/or

- debt securities.

     In this prospectus, we will refer to the common stock and related rights,
preferred stock, depositary shares and debt securities collectively as
"securities." The total dollar amount of all securities that we may issue under
this prospectus will not exceed $1,000,000,000.

     If we issue debt securities at a discount from their original stated
principal amount, then, for purposes of calculating the total dollar amount of
all securities issued under this prospectus, we will treat the initial offering
price of the debt securities as the total original principal amount of the debt
securities.

     This prospectus may not be used to sell securities unless it is accompanied
by a prospectus supplement.

                                        3


                          DESCRIPTION OF CAPITAL STOCK

     The following description of our common stock and preferred stock, together
with the additional information included in any applicable prospectus
supplements, summarizes the material terms and provisions of these types of
securities. For the complete terms of our common stock and preferred stock,
please refer to our charter, bylaws and stockholder rights plan that are
incorporated by reference into the registration statement that includes this
prospectus or may be incorporated by reference in this prospectus. The terms of
these securities may also be affected by the General Corporation Law of the
State of Delaware.

     Under our charter, our authorized capital stock consists of 215,000,000
shares of common stock, $1.25 par value per share, and 5,000,000 shares of
preferred stock, no par value. We will describe the specific terms of any common
stock or preferred stock we may offer in a prospectus supplement. If indicated
in a prospectus supplement, the terms of any common stock or preferred stock
offered under that prospectus supplement may differ from the terms described
below.

                                  COMMON STOCK

     As of March 31, 1999, Apache had approximately 97,820,667 shares of common
stock issued and outstanding. Each outstanding share of common stock currently
has attached to it one preferred share purchase right issued under our
stockholder rights plan, which is summarized below. All outstanding shares of
common stock are duly authorized, validly issued, fully paid and nonassessable.

VOTING

     For all matters submitted to a vote of stockholders, each holder of common
stock is entitled to one vote for each share registered in his or her name on
the books of Apache. Our common stock does not have cumulative voting rights. As
a result, subject to the voting rights of Series B preferred stockholders and
any future holders of preferred stock, persons who hold more than 50% of the
outstanding common stock entitled to elect members of the board of directors can
elect all of the directors who are up for election in a particular year.

DIVIDENDS

     If our board of directors declares a dividend, holders of common stock will
receive payments from the funds of Apache that are legally available to pay
dividends. However, this dividend right is subject to any preferential dividend
rights we have granted to Series B preferred stockholders or may grant to future
holders of preferred stock.

LIQUIDATION

     If Apache is dissolved, the holders of common stock will be entitled to
share ratably in all the assets that remain after we pay our liabilities and any
amounts we may owe to the persons who hold preferred stock.

OTHER RIGHTS AND RESTRICTIONS

     Holders of common stock do not have preemptive rights, and they have no
right to convert their common stock into any other securities. Our common stock
is not subject to redemption by Apache. Our charter and bylaws do not restrict
the ability of a holder of common stock to transfer his or her shares of common
stock.

     When we issue shares of common stock, the shares will be fully paid and
nonassessable. Delaware law provides that, if we make a distribution to our
stockholders other than a distribution of our capital stock, when we are
insolvent, or that renders us insolvent, then our stockholders would be required
to pay back to us the amount of the distribution we made to them, or the portion
of the distribution that causes us to become insolvent.

LISTING

     Our common stock is listed on the New York Stock Exchange and the Chicago
Stock Exchange.

                                        4


TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is Norwest Bank
Minnesota, National Association.

                                PREFERRED STOCK

GENERAL

     We have 5,000,000 shares of no par preferred stock authorized, of which
25,000 shares have been designated as Series A Junior Participating Preferred
Stock and 100,000 shares have been designated as 5.68% Series B Cumulative
Preferred Stock. The remaining shares of preferred stock are undesignated.

     Our charter authorizes our board of directors to issue preferred stock in
one or more series and to determine the voting rights and dividend rights,
dividend rates, liquidation preferences, conversion rights, redemption rights,
including sinking fund provisions and redemption prices, and other terms and
rights of each series of preferred stock.

SERIES A

     The shares of Series A preferred stock are authorized for issuance pursuant
to rights that trade with outstanding Apache common stock and are reserved for
issuance upon the exercise of the rights discussed below under the caption
"-- Stockholder Rights Plan."

SERIES B

     As of March 31, 1999, Apache had issued and outstanding 100,000 shares of
Series B preferred stock in the form of one million depositary shares, each
representing one-tenth ( 1/10) of a share of Series B preferred stock. The
Series B preferred stock has no stated maturity, is not subject to a sinking
fund and is not convertible into Apache common stock or any other securities.
Apache has the option to redeem the Series B preferred stock at $1,000 per share
on or after August 25, 2008. Holders of the shares are entitled to receive
cumulative cash dividends at an annual rate of $5.68 per depositary share when,
and if, declared by Apache's board of directors.

     The Series B preferred stock ranks prior and superior to our common stock
and Series A preferred stock as to payment of dividends and distribution of
assets upon our dissolution, liquidation or winding up.

     If dividends are not paid on the Series B preferred stock, payments on our
common stock are prohibited and payments on any other capital stock are
restricted.

     Shares of Series B preferred stock generally do not have voting rights.
However, if we fail to pay the equivalent of six quarterly dividends payable on
the Series B preferred stock or another class or series of preferred stock that
ranks equally with the Series B preferred stock, then we will increase the size
of our board of directors by two members. The holders of the Series B preferred
stock and any other class or series of preferred stock ranking equally with the
Series B preferred stock, voting as a single class, will then have the right to
vote for the two additional directors. This voting right would continue until we
paid all past dividends on all that preferred stock.

     Without the vote of at least 80% of the outstanding shares of Series B
preferred stock, we may not alter or repeal any provision in our charter so as
to adversely affect the rights of the Series B preferred stock.

UNDESIGNATED PREFERRED STOCK

     This summary of the undesignated preferred stock discusses terms and
conditions that we expect will apply to all series of the preferred stock
offered under this prospectus. The applicable prospectus supplement will
describe the particular terms of each particular series of preferred stock
offered. If indicated in the prospectus supplement, the terms of any series may
differ from the terms described below.

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of any preferred
stock being offered by this prospectus. It does not restate the terms and
provisions in their entirety. We urge you to read our charter and the

                                        5


applicable certificate of designation because they, and not this description,
define the rights of any holders of preferred stock. We have filed our charter
as an exhibit to the registration statement which includes this prospectus. We
will incorporate by reference as an exhibit to the registration statement the
form of any certificate of designation before the issuance of any series of
preferred stock.

     We expect the prospectus supplement to include some or all of the following
terms:

- the designation of the series of preferred stock;

- the number of shares of preferred stock offered, the liquidation preference
  per share and the offering price of the preferred stock;

- the dividend rate or rates of the shares, the dates at which dividends, if
  declared, will be payable, and whether or not the dividends are to be
  cumulative and, if cumulative, the date or dates from which dividends shall be
  cumulative;

- the amounts payable on shares of the preferred stock in the event of our
  voluntary or involuntary liquidation, dissolution or winding up;

- the redemption rights and price or prices, if any, for the shares of preferred
  stock;

- any terms, and the amount, of any sinking fund or analogous fund providing for
  the purchase or redemption of the shares of preferred stock;

- any restrictions on our ability to make payments on any of our capital stock
  if dividend or other payments are not made on the preferred stock;

- any voting rights granted to the holders of the shares of preferred stock in
  addition to those required by Delaware law or our certificate of
  incorporation;

- whether the shares of preferred stock will be convertible into shares of our
  common stock or any other class of our capital stock, and, if convertible, the
  conversion price or prices, and any adjustment or other terms and conditions
  upon which the conversion shall be made;

- any other rights, preferences, restrictions, limitations or conditions
  relative to the shares of preferred stock permitted by Delaware law or our
  certificate of incorporation;

- any listing of the preferred stock on any securities exchange; and

- the federal income tax considerations applicable to the preferred stock.

     Subject to our charter and to any limitations imposed by any
then-outstanding preferred stock, we may issue additional series of preferred
stock, at any time or from time to time, with such powers, preferences, rights
and qualifications, limitations or restrictions, as the board of directors
determines, and without further action of the stockholders, including holders of
our then outstanding preferred stock, if any.

                            STOCKHOLDER RIGHTS PLAN

     In 1995, our board of directors adopted a stockholder rights plan to
replace the former plan adopted in 1986. Under our stockholder rights plan, each
of our common stockholders received a dividend of one "preferred stock purchase
right" for each outstanding share of common stock that the stockholder owned. We
refer to these preferred stock purchase rights as the "rights." Unless the
rights have been previously redeemed, all shares of Apache common stock issued
after the 1996 dividend are issued with rights. The rights trade automatically
with our shares of common stock and become exercisable only under certain
circumstances described below.

     The purpose of the rights is to encourage potential acquirors to negotiate
with our board of directors before attempting a takeover bid and to provide our
board of directors with leverage in negotiating on behalf of our stockholders
the terms of any proposed takeover. The rights may have certain anti-takeover
effects. They should not, however, interfere with any merger or other business
combination approved by our board of directors.

     The following description is a summary of all the material terms of our
stockholder rights plan. It does not restate these terms in their entirety. We
urge you to read our stockholder rights plan because it, and not
                                        6


this description, defines the terms and provisions of our plan. Our stockholder
rights plan is an exhibit to our registration statement on Form 8-A, as amended,
which we filed with the Securities and Exchange Commission on January 24, 1996
and which is incorporated by reference as an exhibit to the registration
statement that includes this prospectus. You may obtain a copy at no charge by
writing to us at the address listed under the caption "Where You Can Find More
Information."

EXERCISE OF RIGHTS

     Until a right is exercised, the holder of a right will not have any rights
as a stockholder. When the rights become exercisable, holders of the rights will
be able to purchase from us 1/10,000th of a share of our Series A preferred
stock, at a purchase price of $100, subject to adjustment, per 1/10,000th of a
share.

     In general, the rights will become exercisable upon the earlier of:

- ten calendar days after a public announcement that a person or group has
  acquired beneficial ownership of 20% or more of the outstanding shares of our
  common stock; or

- ten business days after the beginning of a tender offer or exchange offer that
  would result in a person or group beneficially owning 30% or more of our
  common stock.

FLIP IN EVENT

     If a person or group becomes the beneficial owner of 20% or more of our
common stock, then each right will then entitle its holder to receive, upon
exercise, a number of shares of our common stock which is equal to the exercise
price of the right divided by one-half of the market price of our common stock
on the date of the occurrence of this event. We refer to this occurrence as a
"flip in event." A flip in event does not occur if there is an offer for all of
our outstanding shares of common stock that our board of directors determines is
fair to our stockholders and in Apache's best interests.

FLIP OVER EVENT

     If at any time after a person or group becomes the beneficial owner of 20%
or more of our common stock, Apache is acquired in a merger or other transaction
in which Apache does not survive or in which our common stock is changed or
exchanged or 50% or more of Apache's assets or earning power is sold or
transferred, then each holder of a right will be entitled to receive, upon
exercise, a number of shares of common stock of the acquiring company in the
transaction equal to the exercise price of the right divided by one-half of the
market price of the acquiring company's common stock on the date of the
occurrence of this event. This exercise right will not occur if the merger or
other transaction follows an offer for all of our outstanding shares of common
stock that our board of directors determines is fair to our stockholders and in
Apache's best interests.

EXCHANGE OF RIGHTS

     At any time after a flip in event, our board of directors may exchange the
rights by providing to the holder one share of our common stock or 1/10,000th of
a share of our Series A preferred stock for each of the holder's rights.

REDEMPTION OF RIGHTS

     At any time before a flip in event, we may redeem the rights at a price of
$.01 per right. The rights will expire on the close of business on January 31,
2006, subject to earlier expiration or termination as described in our
stockholder rights plan.

     Unless and until the rights become exercisable, they will be transferred
with and only with the shares of Apache common stock.

 ANTI-TAKEOVER EFFECT OF PROVISIONS OF APACHE'S CHARTER AND BYLAWS AND DELAWARE
                                      LAW

     Apache's charter and bylaws include provisions designed to prevent the use
of certain tactics in connection with a potential takeover of Apache. Please
refer to our charter and bylaws that are incorporated by reference into the
registration statement that

                                        7


includes this prospectus. You may obtain copies at no charge by writing to us at
the address listed under the caption "Where You Can Find More Information."

     Provisions of Delaware law have a similar anti-takeover effect.

APACHE'S BYLAWS

     Apache's board of directors is divided into three classes, with directors
serving staggered three-year terms.

APACHE'S CHARTER

     Article Twelve generally stipulates that the affirmative vote of 80% of our
voting shares is required to adopt any agreement for the merger or consolidation
with or into any other corporation which is the beneficial owner of more than 5%
of our voting shares. Article Twelve further provides that such 80% approval is
necessary to authorize any sale or lease of assets between Apache and any
beneficial holder of 5% or more of our voting shares.

     Article Fourteen contains a "fair price" provision which requires that any
tender offer made by a beneficial owner of more than 5% of our outstanding
voting stock in connection with any:

- plan of merger;

- consolidation or reorganization;

- any sale or lease of substantially all of our assets; or

- any issuance of our equity securities to the 5% stockholder

must provide at least as favorable terms to each holder of common stock other
than the stockholder making the tender offer.

     Article Fifteen contains an "anti-greenmail" mechanism which prohibits
Apache from acquiring any voting stock from the beneficial owner of more than 5%
of the outstanding voting stock, except for acquisitions pursuant to a tender
offer to all holders of voting stock on the same price, terms and conditions,
acquisitions in compliance with Rule 10b-18 of the Securities Exchange Act of
1934 and acquisitions at a price not exceeding the market value per share.

     Article Sixteen prohibits the stockholders from acting by written consent
in lieu of a meeting.

BUSINESS COMBINATIONS WITH INTERESTED STOCKHOLDERS UNDER DELAWARE LAW

     Section 203 of the Delaware General Corporation Law prevents a publicly
held corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless:

- before the date on which the person became an interested stockholder, the
  board of directors of the corporation approved either the business combination
  or the transaction in which the person became an interested stockholder;

- the interested stockholder owned at least 85% of the outstanding voting stock
  of the corporation at the beginning of the transaction in which it became an
  interested stockholder, excluding stock held by directors who are also
  officers of the corporation and by employee stock plans that do not provide
  participants with the rights to determine confidentially whether shares held
  subject to the plan will be tendered in a tender or exchange offer; or

- after the date on which the interested stockholder became an interested
  stockholder, the business combination is approved by the board of directors
  and the holders of two-thirds of the outstanding voting stock of the
  corporation voting at a meeting, excluding the voting stock owned by the
  interested stockholder.

     As defined in Section 203, an "interested stockholder" is generally a
person owning 15% or more of the outstanding voting stock of the corporation. As
defined in Section 203, a "business combination" includes mergers,
consolidations, stock and assets sales and other transactions with the
interested stockholder.

     The provisions of Section 203 may have the effect of delaying, deferring or
preventing a change of control of Apache.

                        DESCRIPTION OF DEPOSITARY SHARES

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the depositary
shares that we may offer under this prospectus and the related deposit
agreements and depositary receipts. Specific deposit agreements and depositary
receipts will contain additional important terms and provisions and will be
incorporated by reference into the registration statement which includes this
prospectus before we issue any depositary shares.

     This summary of depositary agreements, depositary shares and depositary
receipts relates to terms and conditions applicable to these types of securities
generally. The particular terms of any series of depositary shares will be
summarized in the applicable prospectus supplement. If indicated in the
applicable prospectus supplement, the terms of any series may differ from the
terms summarized below.

                                    GENERAL

     We may elect to offer fractional shares of preferred stock rather than full
shares of preferred stock. If so, we will issue "depositary receipts" for these
"depositary shares." Each depositary share will represent a fraction of a share
of a particular series of preferred stock. Each holder of a depositary share
will be entitled, in proportion to the fraction of preferred stock represented
by that depositary share, to the rights and preferences of the preferred stock,
including dividend, voting, redemption, conversion and liquidation rights, if
any. We will enter into a deposit agreement with a depositary, which will be
named in the related prospectus supplement.

     In order to issue depositary shares, we will issue preferred stock and
immediately deposit these shares with the depositary. The depositary will then
issue and deliver depositary receipts to the persons who purchase depositary
shares. Each whole depositary share issued by the depositary may represent a
fraction of a share of preferred stock held by the depositary. The depositary
will issue depositary receipts in a form that reflects whole depositary shares,
and each depositary receipt may evidence any number of whole depositary shares.

     Pending the preparation of definitive engraved depositary receipts, a
depositary may, upon our written order, issue temporary depositary receipts,
which will temporarily entitle the holders to all the rights pertaining to the
definitive depositary receipts. We will bear the costs and expenses of promptly
preparing definitive depositary receipts and of exchanging the temporary
depositary receipts for such definitive depositary receipts.

                       DIVIDENDS AND OTHER DISTRIBUTIONS

     The depositary will distribute all cash and non-cash distributions it
receives with respect to the underlying preferred stock to the record holders of
depositary shares in proportion to the number of depositary shares they hold. In
the case of non-cash distributions, the depositary may determine that the
distribution cannot be made proportionately or that it may not be feasible to
make the distribution. If so, the depositary will, with our approval, adopt a
method it deems equitable and practicable to effect the distribution, including
the sale, public or private, of the securities or other non-cash property it
receives in the distribution at a place and on terms it deems proper. The
amounts distributed by the depositary will be reduced by any amount required to
be withheld by Apache or the depositary on account of taxes.

                        REDEMPTION OF DEPOSITARY SHARES

     If we redeem the series of preferred stock that underlies the depositary
shares, the depositary will redeem the depositary shares from the proceeds it
receives from the redemption of the preferred stock it holds. The depositary
will redeem the number of depositary shares that represent the amount of
underlying preferred stock that we have redeemed. The redemption price for
depositary shares will be in proportion to the redemption price per share that
we paid for the underlying preferred stock. If we redeem less than all of the
depositary shares, the
                                        9


depositary will select which depositary shares to redeem by lot, or some
substantially equivalent method.

     After a redemption date is fixed, the depositary shares to be redeemed no
longer will be considered outstanding. The rights of the holders of the
depositary shares will cease, except for the rights to receive money or other
property upon redemption. In order to redeem their depositary shares, holders
will surrender their depositary receipts to the depositary.

                           VOTING THE PREFERRED STOCK

     We will notify the depositary about any meeting at which the holders of
preferred stock are entitled to vote, and the depositary will mail the
information to the record holders of depositary shares related to that preferred
stock. Each record holder of depositary shares on the record date will be
entitled to instruct the depositary on how to vote the shares of preferred stock
represented by that holder's depositary shares. The depositary will vote the
preferred stock represented by the depositary shares in accordance with these
instructions, provided the depositary receives these instructions sufficiently
in advance of the meeting. If the depositary does not receive instructions from
the holders of the depositary shares, the depositary will abstain from voting
the preferred stock that underlies those depositary shares.

                         WITHDRAWAL OF PREFERRED STOCK

     When a holder surrenders depositary receipts at the corporate trust office
of the depositary, and pays any necessary taxes, charges or other fees, the
holder will be entitled to receive the number of whole shares of the related
series of preferred stock, and any money or other property, if any, represented
by the holder's depositary shares. Once a holder exchanges depositary shares for
whole shares of preferred stock, that holder cannot "re-deposit" these shares of
preferred stock with the depositary, or exchange them for depositary shares. If
a holder delivers depositary receipts that represent a number of depositary
shares that exceeds the number of whole shares of related preferred stock the
holder seeks to withdraw, the depositary will issue a new depositary receipt to
the holder that evidences the excess number of depositary shares.

               AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     Apache and the depositary can agree, at any time, to amend the form of
depositary receipt and any provisions of the deposit agreement. However, if an
amendment has a material adverse effect on the rights of the holders of related
depositary shares, the holders of at least a majority of the depositary shares
then outstanding must first approve the amendment. Every holder of a depositary
receipt at the time an amendment becomes effective will be bound by the amended
deposit agreement. However, subject to any conditions in the deposit agreement
or applicable law, no amendment can impair the right of any holder of a
depositary share to receive shares of the related preferred stock, or any money
or other property represented by the depositary shares, when they surrender
their depositary receipts.

     We can terminate the deposit agreement at any time, as long as the
depositary mails notice of termination to the record holders of depositary
shares then-outstanding at least 30 days prior to the date fixed for
termination.

                             CHARGES OF DEPOSITARY

     We will pay all transfer and other taxes and the government charges that
relate solely to the depositary arrangements. We will also pay the charges of
each depositary, including charges in connection with the initial deposit of the
related series of preferred stock, the initial issuance of the depositary
shares, and all withdrawals of shares of the related series of preferred stock.
However, holders of depositary shares will be required to pay transfer and other
taxes and government charges, as provided in the deposit agreement.

                     RESIGNATION AND REMOVAL OF DEPOSITARY

     The depositary may resign at any time by delivering written notice of its
decision to us.

                                        10


We may remove the depositary at any time. Any resignation or removal will take
effect when we appoint a successor depositary. We must appoint the successor
depositary within 60 days after delivery of the notice of resignation or
removal. The successor depositary must be a bank or trust company that has its
principal office in the United States and has a combined capital and surplus of
at least $50,000,000.

                                 MISCELLANEOUS

     We will be required to furnish certain information to the holders of the
preferred stock underlying any depositary shares. The depositary, as the holder
of the underlying preferred stock, will forward any report or information it
receives from us to the holders of depositary shares.

     Neither the depositary nor Apache will be liable if its ability to perform
its obligations under the deposit agreement is prevented or delayed by law or
any circumstance beyond its control. Both Apache and the depositary will be
obligated to use their best judgment and to act in good faith in performing its
duties under the deposit agreement. Each of Apache and the depositary will be
liable only for gross negligence and willful misconduct in performing their
duties under the deposit agreement. They will not be obligated to appear in,
prosecute or defend any legal proceeding with respect to any depositary
receipts, depositary shares or preferred stock unless they receive what they, in
their sole discretion, determine to be a satisfactory indemnity from one or more
holders of the depositary shares. Apache and the depositary will evaluate any
proposed indemnity in order to determine whether the financial protection
afforded by the indemnity is sufficient to reduce each party's risk to a
satisfactory and customary level. Apache and the depositary may rely on the
advice of legal counsel or accountants of their choice. They may also rely on
information provided by persons they believe, in good faith, to be competent,
and on documents they believe, in good faith, to be genuine.

     The applicable prospectus supplement will identify the depositary's
corporate trust office. Unless the prospectus supplement indicates otherwise,
the depositary will act as transfer agent and registrar for depositary receipts,
and if we redeem shares of preferred stock, the depositary will act as
redemption agent for the corresponding depositary receipts.

                                     TITLE

     Apache, each depositary and any agent of Apache or the applicable
depositary may treat the registered owner of any depositary share as the
absolute owner of the depositary shares for all purposes, including making
payment, regardless of whether any payment in respect of the depositary share is
overdue and regardless of any notice to the contrary. See "Book-Entry
Securities" below.

                                        11


                         DESCRIPTION OF DEBT SECURITIES

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the debt
securities that we may offer under this prospectus and the related trust
indenture. The indenture under which debt securities will be issued contains
additional important terms and provisions and is or will be filed as an exhibit
to the registration statement that includes this prospectus.

     This summary of the indenture and the debt securities relates to terms and
conditions applicable to the debt securities generally. The particular terms of
any series of debt securities will be summarized in the applicable prospectus
supplement. If indicated in the prospectus supplement, the terms of any series
may differ from the terms summarized below.

     Unless otherwise specified in the applicable prospectus supplement, we will
issue the debt securities under an indenture entered into between us and The
Chase Manhattan Bank, as trustee. We may only offer up to $1,000,000,000 of debt
securities under this prospectus. However, the indenture does not limit the
amount of debt securities we may issue under the indenture and provides that
additional debt securities of any series may be issued up to the aggregate
principal amount that we authorize from time to time. Debt securities may also
be issued pursuant to the indenture in transactions exempt from the registration
requirements of the Securities Act of 1933. Those debt securities will not be
considered in determining the aggregate amount of securities issued under this
prospectus.

     Unless otherwise indicated in the applicable prospectus supplement, we will
issue the debt securities in denominations of $1,000 or integral multiples of
$1,000.

     Unless otherwise indicated in the applicable prospectus supplement, the
payment of principal of, and any premium and interest on, the debt securities
will rank pari passu with all of our other unsecured unsubordinated
indebtedness. Principal and any premium and any interest will be payable, and
the debt securities will be transferable, at the corporate trust office of the
appropriate trustee, unless we specify otherwise in the accompanying prospectus
supplement. At our option, however, payment of interest may be made by check
mailed to the registered holders of the debt securities at their registered
addresses.

     We will describe special U.S. federal income tax and other considerations
relating to debt securities denominated in foreign currencies or units of two or
more foreign currencies in the applicable prospectus supplement.

     Unless we specify otherwise in the applicable prospectus supplement, the
covenants contained in the indenture and the debt securities will not provide
special protection to holders of debt securities if we enter into a highly
leveraged transaction, recapitalization or restructuring.

                                    GENERAL

     The prospectus supplement relating to the particular series of debt
securities being offered will specify the amounts, prices and terms of those
debt securities. These terms may include:

- the designation, aggregate principal amount and authorized denominations of
  the debt securities;

- the date or dates on which the debt securities will mature;

- the percentage of the principal amount at which the debt securities will be
  issued;

- the date on which the principal of the debt securities will be payable;

- whether the debt securities will be issued as registered securities, bearer
  securities or a combination of the two;

- whether the debt securities will be issued in the form of one or more global
  securities and whether such global securities will be issued in a temporary
  global form or permanent global form;

                                        12


- the currency or currencies or units of two or more currencies in which debt
  securities are denominated, for which they may be purchased, and in which
  principal and any premium and interest is payable;

- if the currency or currencies or currency unit or units for which debt
  securities may be purchased or in which principal and any premium interest may
  be paid is at our election or at the election of a purchaser, the manner in
  which an election may be made and its terms;

- the annual rate or rates, which may be fixed or variable, or the method of
  determining the rate or rates at which the debt securities will bear interest;

- the date or dates from which any interest will accrue and the date or dates on
  which such interest will be payable;

- a description of any provisions providing for redemption, exchange or
  conversion of the debt securities at our option or a holder's option and the
  terms and provisions of such redemption, exchange or conversion;

- information with respect to book-entry procedures relating to global debt
  securities;

- any redemption or sinking fund terms;

- whether and under what circumstances we will pay "additional amounts," as
  defined in the indenture, on the debt securities to any holder who is a
  "United States alien," as defined in the indenture, in respect of any tax,
  assessment or governmental charge and, if so, whether and on what terms we
  will have the option to redeem the debt securities rather than pay any
  additional amounts. The term "interest," as used in this prospectus, includes
  any additional amounts;

- any events of default or covenants of Apache with respect to the debt
  securities of a certain series that are different from those described in this
  prospectus;

- if either or both of Section 402(2) of the indenture relating to defeasance or
  Section 402(3) of the indenture relating to covenant defeasance is not
  applicable to the debt securities, or if any covenants in addition to those
  specified in Section 402(3) of the indenture shall be subject to covenant
  defeasance;

- any deletions from, or modifications or additions to, the provisions of the
  indenture relating to satisfaction and discharge in respect of the debt
  securities;

- any index or other method used to determine the amount of payments of
  principal of, and any premium and interest on, the debt securities; and

- any other specific terms of the debt securities.

     We are not obligated to issue all debt securities of any one series at the
same time. The debt securities of any one series may not bear interest at the
same rate or mature on the same date.

     If any of the debt securities are sold for foreign currencies or foreign
currency units or if the principal of, or any premium or interest on, any series
of debt securities is payable in foreign currencies or foreign currency units,
we will describe the restrictions, elections, tax consequences, specific terms
and other information with respect to those debt securities and such foreign
currencies or foreign currency units in the applicable prospectus supplement.

     Other than as described below under "The Indenture Limits Our Ability to
Incur Liens," "The Indenture Limits Our Ability to Engage in Sale/Leaseback
Transactions" and "We Are Obligated to Purchase Debt Securities on a Change in
Control," the indenture does not limit our ability to incur indebtedness or
afford holders of debt securities protection in the event of a decline in our
credit quality or if we are involved in a takeover, recapitalization or highly
leveraged or similar transaction. The prospectus supplement relating to the
particular series of debt securities, to the extent not otherwise described in
this prospectus, will include any information with respect to any deletions
from, modifications of or additions to the events of default described below and
contained in the indenture, including any

                                        13


addition of a covenant or other provision providing event risk or similar
protection.

                          INTEREST RATES AND DISCOUNTS

     The debt securities will earn interest at a fixed or floating rate or rates
for the period or periods of time specified in the applicable prospectus
supplement. Unless otherwise specified in the applicable prospectus supplement,
the debt securities will bear interest on the basis of a 360-day year consisting
of twelve 30-day months.

     We may sell debt securities at a substantial discount below their stated
principal amount, bearing no interest or interest at a rate that at the time of
issuance is below market rates. Federal income tax consequences and special
considerations that apply to any series will be described in the applicable
prospectus supplement.

                      EXCHANGE, REGISTRATION AND TRANSFER

     Registered securities of any series that are not global securities will be
exchangeable for other registered securities of the same series and of like
aggregate principal amount and tenor in different authorized denominations. In
addition, if debt securities of any series are issuable as both registered
securities and bearer securities, the holder may choose, upon written request,
and subject to the terms of the indenture, to exchange bearer securities and the
appropriate related coupons of that series into registered securities of the
same series of any authorized denominations and of like aggregate principal
amount and tenor. Bearer securities with attached coupons surrendered in
exchange for registered securities between a regular record date or a special
record date and the relevant date for interest payment shall be surrendered
without the coupon relating to the interest payment date. Interest will not be
payable with respect to the registered security issued in exchange for that
bearer security. That interest will be payable only to the holder of the coupon
when due in accordance with the terms of the indenture. Bearer securities will
not be issued in exchange for registered securities.

     You may present registered securities for registration of transfer,
together with a duly executed form of transfer, at the office of the security
registrar or at the office of any transfer agent designated by us for that
purpose with respect to any series of debt securities and referred to in the
applicable prospectus supplement. This may be done without service charge but
upon payment of any taxes and other governmental charges as described in the
indenture. The security registrar or the transfer agent will effect the transfer
or exchange upon being satisfied with the documents of title and identity of the
person making the request. We have appointed the trustee as security registrar
for the indenture. If a prospectus supplement refers to any transfer agents
initially designated by us with respect to any series of debt securities in
addition to the security registrar, we may at any time rescind the designation
of any of those transfer agents or approve a change in the location through
which any of those transfer agents acts. However, if debt securities of a series
are issuable solely as registered securities, we will be required to maintain a
transfer agent in each place of payment for that series, and if debt securities
of a series are issuable as bearer securities, we will be required to maintain a
transfer agent in a place of payment for that series located in Europe in
addition to the security registrar. We may at any time designate additional
transfer agents with respect to any series of debt securities.

     In the event of any redemption, we will not be required to:

- issue, register the transfer of or exchange debt securities of any series
  during a period beginning at the opening of business 15 days before any
  selection of debt securities of that series to be redeemed and ending at the
  close of business on the day of mailing of the relevant notice of redemption;
  or

- register the transfer of or exchange any registered security, or portion
  thereof, called for redemption, except the unredeemed portion of any
  registered security being redeemed in part.

                                        14


                           PAYMENT AND PAYING AGENTS

     Unless we specify otherwise in the applicable prospectus supplement,
payment of principal of, and any premium and interest on, bearer securities will
be payable in accordance with any applicable laws and regulations, at the
offices of those paying agents outside the United States that we may designate
at various times. We will make interest payments on bearer securities and the
attached coupons on any interest payment date only against surrender of the
coupon relating to that interest payment date. No payment with respect to any
bearer security will be made at any of our offices or agencies in the United
States by check mailed to any U.S. address or by transfer to an account
maintained with a bank located in the United States. However, if, but only if,
payment in U.S. dollars of the full amount of principal of, and any premium and
interest on, bearer securities denominated and payable in U.S. dollars at all
offices or agencies outside the United States is illegal or effectively
precluded by exchange controls or other similar restrictions, then those
payments will be made at the office of our paying agent in the Borough of
Manhattan, The City of New York.

     Unless we specify otherwise in the applicable prospectus supplement,
payment of principal of, and any premium and interest on, registered securities
will be made at the office of the paying agent or paying agents that we
designate at various times. However, at our option, we may make interest
payments by check mailed to the address, as it appears in the security register,
of the person entitled to the payments. Unless we specify otherwise in the
applicable prospectus supplement, we will make payment of any installment of
interest on registered securities to the person in whose name that registered
security is registered at the close of business on the regular record date for
such interest.

     Unless we specify otherwise in the applicable prospectus supplement, the
Corporate Trust Office of the trustee in the Borough of Manhattan, The City of
New York, will be designated:

- as our sole paying agent for payments with respect to debt securities that are
  issuable solely as registered securities; and

- as our paying agent in the Borough of Manhattan, The City of New York, for
  payments with respect to debt securities, subject to the limitation described
  above in the case of bearer securities, that are issuable solely as bearer
  securities or as both registered securities and bearer securities.

     We will name any paying agents outside the United States and any other
paying agents in the United States initially designated by us for the debt
securities in the applicable prospectus supplement. We may at any time designate
additional paying agents or rescind the designation of any paying agent or
approve a change in the office through which any paying agent acts. However, if
debt securities of a series are issuable solely as registered securities, we
will be required to maintain a paying agent in each place of payment for that
series. If debt securities of a series are issuable as bearer securities, we
will be required to maintain:

- a paying agent in the Borough of Manhattan, The City of New York, for payments
  with respect to any registered securities of the series and for payments with
  respect to bearer securities of the series in the circumstance described
  above, but not otherwise; and

- a paying agent in a place of payment located outside the United States where
  debt securities of that series and any attached coupons may be presented and
  surrendered for payment.

     However, if the debt securities of that series are listed on the London
Stock Exchange, the Luxembourg Stock Exchange or any other stock exchange
located outside the United States and if the stock exchange requires it, we will
maintain a paying agent in London or Luxembourg or any other required city
located outside the United States for those debt securities.

                                        15


     All moneys we pay to a paying agent for the payment of principal of, and
any premium or interest on, any debt security or coupon that remains unclaimed
at the end of two years after becoming due and payable will be repaid to us.
After that time, the holder of the debt security or coupon will look only to us
for payments out of those repaid amounts.

                               GLOBAL SECURITIES

     The debt securities of a series may be issued in whole or in part in the
form of one or more global certificates that we will deposit with a depositary
identified in the applicable prospectus supplement. Global securities may be
issued in either registered or bearer form and in either temporary or permanent
form. Unless and until it is exchanged in whole or in part for the individual
debt securities it represents, a global security may not be transferred except
as a whole:

- by the applicable depositary to a nominee of the depositary;

- by any nominee to the depositary itself or another nominee; or

- by the depositary or any nominee to a successor depositary or any nominee of
  the successor.

     We will describe the specific terms of the depositary arrangement with
respect to a series of debt securities in the applicable prospectus supplement.
We anticipate that the following provisions will generally apply to depositary
arrangements.

     When we issue a global security in registered form, the depositary for the
global security or its nominee will credit, on its book-entry registration and
transfer system, the respective principal amounts of the individual debt
securities represented by that global security to the accounts of participants
that have accounts with the depositary. Those accounts will be designated by the
dealers, underwriters or agents with respect to the underlying debt securities
or by us if those debt securities are offered and sold directly by us. Ownership
of beneficial interests in a global security will be limited to participants or
persons that may hold interests through participants. For interests of
participants, ownership of beneficial interests in the global security will be
shown on records maintained by the applicable depositary or its nominee. For
interests of persons other than participants, that ownership information will be
shown on the records of participants. Transfer of that ownership will be
effected only through those records. The laws of some states require that
certain purchasers of securities take physical delivery of securities in
definitive form. These limits and laws may impair our ability to transfer
beneficial interests in a global security.

     As long as the depositary for a global security, or its nominee, is the
registered owner of that global security, the depositary or nominee will be
considered the sole owner or holder of the debt securities represented by the
global security for all purposes under the applicable indenture. Except as
provided below, owners of beneficial interests in a global security:

- will not be entitled to have any of the underlying debt securities registered
  in their names;

- will not receive or be entitled to receive physical delivery of any of the
  underlying debt securities in definitive form; and

- will not be considered the owners or holders under the indenture relating to
  those debt securities.

     Payments of principal of, and any premium and interest on, individual debt
securities represented by a global security registered in the name of a
depositary or its nominee will be made to the depositary or its nominee as the
registered owner of the global security representing such debt securities.
Neither we, the trustee, any paying agent nor the registrar for the debt
securities will be responsible for any aspect of the records relating to or
payments made by the depositary or any participants on account of beneficial
interests of the global security.

     We expect that the depositary or its nominee, upon receipt of any payment
of principal, premium or interest relating to a permanent global security
representing any series of debt securities, immediately will credit
participants' accounts with the
                                        16


payments. Those payments will be credited in amounts proportional to the
respective beneficial interests of the participants in the principal amount of
the global security as shown on the records of the depositary or its nominee. We
also expect that payments by participants to owners of beneficial interests in
the global security held through those participants will be governed by standing
instructions and customary practices. This is now the case with securities held
for the accounts of customers in bearer form or registered in "street name."
Those payments will be the sole responsibility of those participants.

     If the depositary for a series of debt securities is at any time unwilling,
unable or ineligible to continue as depositary and we do not appoint a successor
depositary within 90 days, we will issue individual debt securities of that
series in exchange for the global security or securities representing that
series. In addition, we may at any time in our sole discretion determine not to
have any debt securities of a series represented by one or more global
securities. In that event, we will issue individual debt securities of that
series in exchange for the global security or securities. Further, if we
specify, an owner of a beneficial interest in a global security may, on terms
acceptable to us, the trustee and the applicable depositary, receive individual
debt securities of that series in exchange for those beneficial interests. The
foregoing is subject to any limitations described in the applicable prospectus
supplement. In that instance, the owner of the beneficial interest will be
entitled to physical delivery of individual debt securities equal in principal
amount to the beneficial interest and to have the debt securities registered in
its name. Those individual debt securities will be issued in denominations,
unless we specify otherwise, of $1,000 or integral multiples of $1,000.

     For a description of the depository arrangements for global securities held
by The Depository Trust Company, see "Book-Entry Securities."

                THE INDENTURE LIMITS OUR ABILITY TO INCUR LIENS

     Nothing in the indenture or the debt securities will in any way limit the
amount of indebtedness or securities which we or our subsidiaries, as defined in
the indenture, may incur or issue. The indenture provides that neither us nor
any of our subsidiaries may issue, assume or guarantee any notes, bonds,
debentures or other similar evidences of indebtedness for money borrowed secured
by a mortgage, lien, pledge, security interest or other encumbrance -- defined
in the indenture as "liens" -- upon any of its property unless we provide that
any and all debt securities then outstanding shall be secured by a lien equally
and ratably with any and all other obligations by the lien. The restrictions on
liens will not, however, apply to:

- liens existing on the date of the indenture or provided for under the terms of
  agreements existing on the date thereof;

- liens securing all or part of the cost of exploring, producing, gathering,
  processing, marketing, drilling or developing any of our or our subsidiaries'
  properties, or securing indebtedness incurred to provide funds therefor or
  indebtedness incurred to finance all or part of the cost of acquiring,
  constructing, altering, improving or repairing any such property or assets, or
  securing indebtedness incurred to provide funds therefor;

- liens securing only indebtedness owed by us or one of our subsidiaries to us
  or to one or more of our subsidiaries;

- liens on the property of any corporation or other entity existing at the time
  it becomes our subsidiary;

- liens on any property to secure indebtedness incurred in connection with the
  construction, installation or financing of pollution control or abatement
  facilities or other forms of industrial revenue bond financing or indebtedness
  issued or guaranteed by the United States, any state or any department, agency
  or instrumentality of either or indebtedness issued to or guaranteed for the
  benefit of a

                                        17


  foreign government, any state or any department, agency or instrumentality of
  either or an international finance agency or any division or department
  thereof, including the World Bank, the International Finance Corp. and the
  Multilateral Investment Guarantee Agency;

- any extension, renewal or replacement or successive extensions, renewals or
  replacements of any lien referred to in the foregoing clauses that existed on
  the date of the indenture;

- certain other liens incurred in the ordinary course of business; or

- liens which secure "Limited Recourse Indebtedness," as defined in the
  indenture.

     In addition, the following types of transactions, among others, shall not
be deemed to create indebtedness secured by liens:

- the sale or other transfer of crude oil, natural gas or other petroleum
  hydrocarbons in place for a period of time until, or in an amount such that,
  the transferee will receive as a result of the transfer a specified amount of
  money or of such crude oil, natural gas or other petroleum hydrocarbons;

- the sale or other transfer of any other interest in property of the character
  commonly referred to as a production payment, overriding royalty, forward sale
  or similar interest; and

- liens required by any contract or statute in order to permit us or one of our
  subsidiaries to perform any contract or subcontract made by it with or at the
  request of the U.S. government or any foreign government or international
  finance agency, any state or any department thereof, or any agency or
  instrumentality of either, or to secure partial, progress, advance or other
  payments to us or one of our subsidiaries by any of these entities pursuant to
  the provisions of any contract or statute.

   THE INDENTURE LIMITS OUR ABILITY TO ENGAGE IN SALE/LEASEBACK TRANSACTIONS

     Unless we specify otherwise in the applicable prospectus supplement,
neither we nor any of our subsidiaries will enter into any arrangement with any
person, other than us or one of our subsidiaries, to lease any property to us or
a subsidiary of ours for more than three years. For the restriction to apply, we
or one of our subsidiaries must sell or plan to sell the property to the person
leasing it to us or our subsidiary or to another person to which funds have been
or are to be advanced on the security of the leased property. The limitation
does not apply where:

- either we or our subsidiary would be entitled to create debt secured by a lien
  on the property to be leased in a principal amount equal to or exceeding the
  value of that sale/leaseback transaction;

- since the date of the indenture and within a period commencing six months
  prior to the consummation of that arrangement and ending six months after the
  consummation of the arrangement, we have or our subsidiary has expended or
  will expend for any property -- including amounts expended for the
  acquisition, exploration, drilling or development thereof, and for additions,
  alterations, improvements and repairs to the property -- an amount equal to
  all or a portion of the net proceeds of that arrangement and we designate such
  amount as a credit against that arrangement, with any that amount not being so
  designated to be applied as set forth in the next item; or

- during or immediately after the expiration of the 12 months after the
  effective date of that transaction, we apply to the voluntary defeasance or
  retirement of the debt securities and or other senior indebtedness, as defined
  in the indenture, an amount equal to the greater of the net proceeds of the
  sale or transfer of the property leased in that transaction or the fair value
  of such property at the time of entering into such transaction, in either case
  adjusted to reflect the remaining term of the lease and any amount we utilize
  as set forth in the prior item. The amount will be reduced by

                                        18


  the principal amount of senior indebtedness we voluntarily retire within that
  12-month period.

                    THE INDENTURE INCLUDES EVENTS OF DEFAULT

     Unless otherwise specified in the applicable prospectus supplement, any one
of the following events will constitute an "event of default" under the
indenture with respect to the debt securities of any series:

- if we fail to pay any interest on any debt security of that series when due,
  and the failure continues for 30 days;

- if we fail to pay principal of or any premium on the debt securities of that
  series when due and payable, either at maturity or otherwise;

- if we fail to perform, or we breach any of our other covenants or warranties
  in the indenture or the debt securities -- other than a covenant or warranty
  included in the indenture solely for the benefit of a series of securities
  other than the debt securities -- and that breach of failure continues for 60
  days after written notice as provided in the indenture;

- if any of our indebtedness, as defined in the indenture, in excess of an
  aggregate of $25,000,000 in principal amount is accelerated under any event of
  default as defined in any mortgage, indenture or instrument and the
  acceleration has not been rescinded or annulled within 30 days after written
  notice as provided in the indenture specifying such event of default and
  requiring us to cause that acceleration to be rescinded or annulled;

- if we fail to pay, bond or otherwise discharge within 60 days of entry, a
  judgment, court order or uninsured monetary damage award against us in excess
  of an aggregate of $25,000,000 which is not stayed on appeal or otherwise
  being appropriately contested in good faith;

- certain events of bankruptcy, insolvency or reorganization involving us; and

- any other event of default provided with respect to the debt securities of
  that series.

     If an event of default with respect to the debt securities of any series,
other than an event of default described in the second to last and third to last
items above, occurs and is continuing, either the trustee or the holders of at
least 25% in aggregate principal amount of the outstanding debt securities of
that series may declare the principal amount of the debt securities to be due
and payable immediately. At any time after a declaration of acceleration has
been made, but before a judgment or decree for payment of money has been
obtained by the trustee, and subject to applicable law and certain other
provisions of the indenture, the holders of a majority in aggregate principal
amount of the debt securities of that series may, under certain circumstances,
rescind and annul such acceleration. If an event of default described in the
second to last and third to last items above occurs, the principal amount and
accrued interest -- or a lesser amount as provided for in the debt securities of
that series -- will become immediately due and payable without any declaration
or other act by the trustee or any holder.

     Within 90 days after the occurrence of any event of default under the
indenture with respect to the debt securities of any series, the trustee must
transmit notice of the event of default to the holders of the debt securities of
that series unless the event of default has been cured or waived. However,
except in the case of a payment default, the trustee may withhold the notice if
and so long as the board of directors, the executive committee or a trust
committee of directors or responsible officers of the trustee has in good faith
determined that the withholding of the notice is in the interest of the holders
of debt securities of that series.

     If an event of default occurs and is continuing with respect to the debt
securities of any series, the trustee may in its discretion proceed to protect
and enforce its rights and the rights of the holders of debt securities of that
series by all appropriate judicial proceedings.

     Subject to the duty of the trustee during any default to act with the
required standard of care, the trustee is under no obligation to

                                        19


exercise any of its rights or powers under the indenture at the request or
direction of any of the holders of debt securities, unless the holders offer the
trustee reasonable indemnity. Subject to indemnifying of the trustee, and
subject to applicable law and certain other provisions of the indenture, the
holders of a majority in aggregate principal amount of the outstanding debt
securities of a series may direct the time, method and place of conducting any
proceeding for any remedy available to the trustee, or exercising any trust or
power conferred on the trustee, with respect to the debt securities of that
series.

      WE ARE OBLIGATED TO PURCHASE DEBT SECURITIES ON A CHANGE IN CONTROL

     If a change in control, as defined in the indenture, occurs, within 15 days
we must mail a written notice regarding the change in control to the trustee and
to every holder of the debt securities of each series. The notice must also be
published at least once in an authorized newspaper, as defined in the indenture,
and must state:

- the event causing the change in control and the date thereof;

- the date by which notice of the change in control is required by the indenture
  to be given;

- the date, 35 business days after the occurrence of the change in control, by
  which we must purchase debt securities we are obligated to purchase pursuant
  to the selling holder's exercise of rights on change in control;

- the price we must pay for the debt securities we are obligated to purchase;

- the name and address of the trustee;

- the procedure for surrendering debt securities to the trustee or other
  designated office or agent for payment;

- a statement of our obligation to make prompt payment on proper surrender of
  the debt securities;

- the procedure for holders' exercise of rights of sale of the debt securities;
  and

- the procedures by which a holder may withdraw such a notice after it is given.

     After we give this notice we will obligated, at the election of each
holder, to purchase such debt securities. Under the indenture, a change in
control is deemed to have occurred when:

- any event requiring the filing of any report under or in response to Schedule
  13D or 14D-1 pursuant to the Securities Exchange Act of 1934 disclosing
  beneficial ownership of either 50% or more of the our common stock then
  outstanding or 50% or more of the voting power of the our voting stock then
  outstanding;

- the completion of any sale, transfer, lease, or conveyance of our properties
  and assets substantially as an entirety to any person or persons that is not
  our subsidiary, as those terms are defined in the indenture; or

- the completion of a consolidation or merger of us with or into any other
  person or entity in a transaction in which either we are not the sole
  surviving corporation or our common stock existing prior to the transaction is
  converted into cash, securities or other property and those exchanging our
  common stock do not, as a result of the transaction, receive either 75% or
  more of the survivor's common stock or 75% or more of the voting power of the
  survivor's voting stock.

     We will not purchase any debt securities if there has occurred and is
continuing an event of default under the indenture, other than default in
payment of the purchase price payable for the debt securities upon change in
control. In connection with any purchase of debt securities after a change in
control, we will comply with all federal and state securities laws, including,
specifically, Rule 13E-4, if applicable, of the Securities Exchange Act, and any
related Schedule 13E-4 required to be submitted under that rule.

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     We may discharge certain obligations to holders of any series of debt
securities that

                                        20


have not already been delivered to the trustee for cancellation and that:

- have become due and payable;

- will become due and payable within one year; or

- are scheduled for redemption within one year.

To discharge the obligations with respect to a series of debt securities, we
must deposit with the trustee, in trust, an amount of funds in U.S. dollars or
in the foreign currency in which those debt securities are payable sufficient to
pay the entire amount of principal of, and any premium or interest on, those
debt securities to the date of the deposit if those debt securities have become
due and payable or to the maturity of the debt securities, as the case may be.

     The indenture provides that, unless the provisions of section 402 of the
indenture are made inapplicable to the debt securities, we may elect either

- to defease and be discharged from any and all obligations with respect to
  those debt securities, which we refer to as "legal defeasance"; or

- to be released from its obligations with respect to such debt securities under
  the covenants described in "The Indenture Limits Our Ability to Incur Liens"
  and "The Indenture Limits Our Ability to Engage in Sale/Leaseback
  Transactions" above or, if provided pursuant to section 301 of the indenture,
  its obligations with respect to any other covenant, which we refer to as
  "covenant defeasance."

     In the case of legal defeasance we will still retain some obligations in
respect of the debt securities, including or obligations:

- to pay additional amounts, if any, upon the occurrence of certain events of
  taxation, assessment or governmental charge with respect to payments on the
  debt securities;

- to register the transfer or exchange of the debt securities;

- to replace temporary or mutilated, destroyed, lost or stolen debt securities;
  and

- to maintain an office or agency with respect to the debt securities and to
  hold moneys for payment in trust.

     After a covenant defeasance, any omission to comply with the obligations or
covenants that have been defeased shall not constitute a default or an event of
default with respect to the debt securities.

     To elect either legal defeasance or covenant defeasance we must deposit
with the trustee, in trust, an amount, in U.S. dollars or in the foreign
currency in which the relevant debt securities are payable at stated maturity,
or in government obligations, as defined below, or both, applicable to such debt
securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient to pay
the principal of and any premium and interest on those debt securities on their
scheduled due dates.

     In addition, we can only elect legal defeasance or covenant defeasance if,
among other things:

- the applicable defeasance does not result in a breach or violation of, or
  constitute a default under, the indenture or any other material agreement or
  instrument to which we are a party or by which we are is bound;

- no default or event of default with respect to the debt securities to be
  defeased shall have occurred and be continuing on the date of the
  establishment of such a trust; and

- we have delivered to the trustee an opinion of counsel to the effect that the
  holders of such debt securities will not recognize income, gain or loss for
  U.S. federal income tax purposes as a result of such defeasance and will be
  subject to U.S. federal income tax on the same amounts, in the same manner and
  at the same times as would have been the case if such defeasance had not
  occurred, and such

                                        21


  opinion of counsel, in the case of legal defeasance, must refer to and be
  based upon a letter ruling of the Internal Revenue Service received by us, a
  Revenue Ruling published by the Internal Revenue Service or a change in
  applicable U.S. federal income tax law occurring after the date of the
  indenture.

     The indenture deems a foreign currency to be any currency, currency unit or
composite currency, including, without limitation, the ECU, issued by the
government of one or more countries other than the United States or by any
recognized confederation or association of governments.

     The indenture defines government obligations as securities which are not
callable or redeemable at the option of the issuer or issuers thereof and are:

- direct obligations of the United States or the government or the governments
  in the confederation which issued the foreign currency in which the debt
  securities of a particular series are payable, for the payment of which its
  full faith and credit is pledged; or

- obligations of a person or entity controlled or supervised by and acting as an
  agency or instrumentality of the United States or the government or
  governments which issued the foreign currency in which the debt securities of
  a particular series are payable, the timely payment of which is
  unconditionally guaranteed as a full faith and credit obligation by the United
  States or that other government or governments.

Government obligations also include a depository receipt issued by a bank or
trust company as custodian with respect to any government obligation described
above or a specific payment of interest on or principal of or any other amount
with respect to any government obligation held by that custodian for the account
of the holder of such depository receipt, as long as, except as required by law,
that custodian is not authorized to make any deduction from the amount payable
to the holder of the depository receipt from any amount received by the
custodian with respect to the government obligation or the specific payment of
interest on or principal of or any other amount with respect to the government
obligation evidenced by the depository receipt.

     Unless we disclose otherwise in the applicable prospectus supplement, if
after we have deposited funds and/or government obligations to effect legal
defeasance or covenant defeasance with respect to debt securities of any series,
either:

- the holder of a debt security of that series is entitled to, and does, elect
  to receive payment in a currency other than that in which such deposit has
  been made in respect of that debt security; or

- a conversion event, as defined below, occurs in respect of the foreign
  currency in which the deposit has been made,

the indebtedness represented by that debt security shall be deemed to have been,
and will be, fully discharged and satisfied through the payment of the principal
of, and any premium and interest on, that debt security as that debt security
becomes due out of the proceeds yielded by converting the amount or other
properties so deposited in respect of that debt security into the currency in
which that debt security becomes payable as a result of the election or
conversion event based on:

- in the case of payments made pursuant to the first of the two items in the
  list above, the applicable market exchange rate for the currency in effect on
  the second business day prior to the date of the payment; or

- with respect to a conversion event, the applicable market exchange rate for
  such foreign currency in effect, as nearly as feasible, at the time of the
  conversion event.

     The indenture defines a "conversion event" as the cessation of use of:

- a foreign currency other than the ECU both by the government of the country or
  the confederation which issued such foreign currency and for the settlement of
  transactions by a central bank or other

                                        22


  public institutions of or within the international banking community;

- the ECU both within the European Monetary System and for the settlement of
  transactions by public institutions of or within the European Community; or

- any currency unit or composite currency other than the ECU for the purposes
  for which it was established. Unless otherwise provided in the applicable
  prospectus supplement, all payments of principal of, and any premium and
  interest on, any debt security that are payable in a foreign currency that
  ceases to be used by the government or confederation of issuance shall be made
  in U.S. dollars.

     If we effect a covenant defeasance with respect to any debt securities and
the debt securities are declared due and payable because of the occurrence of
any event of default other than an event of default with respect to which there
has been covenant defeasance, the amount in the foreign currency in which the
debt securities are payable, and government obligations on deposit with the
trustee, will be sufficient to pay amounts due on the debt securities at the
time of the stated maturity but may not be sufficient to pay amounts due on the
debt securities at the time of the acceleration resulting from the event of
default. However, we would remain liable for payment of the amounts due at the
time of acceleration.

     The applicable prospectus supplement may further describe the provisions,
if any, permitting defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the debt
securities of or within a particular series.

     Under the indenture, we are required to furnish to the trustee annually a
statement as to our performance of certain of our obligations under the
indenture and as to any default in such performance. We are also required to
deliver to the trustee, within five days after occurrence thereof, written
notice of any event which after notice or lapse of time or both would constitute
an event of default.

                            MODIFICATION AND WAIVER

     We and the trustee may modify the indenture or waive certain provisions of
the indenture with the consent of the holders of not less than a majority in
aggregate principal amount of the debt securities of each series affected by the
modification or waiver. However, provisions of the indenture may not be waived
or modified without the consent of the holder of each debt security affected
thereby if the modification or waiver would:

- change the stated maturity of the principal of, or premium, if any, on, or any
  installment of principal, if any, of or interest on, or any additional amounts
  with respect to, any debt security;

- reduce the principal amount of, or premium or interest on, or any additional
  amounts with respect to, any debt security;

- change the coin or currency in which any debt security or any premium or any
  interest on such debt security or any additional amounts with respect to the
  debt security is payable;

- impair the right to institute suit for the enforcement of any payment on or
  after the stated maturity of any debt securities or, in the case of
  redemption, exchange or conversion, on or after the redemption, exchange or
  conversion date or, in the case of repayment at the option of any holder, on
  or after the date for repayment or in the case of a change in control, after
  the change in control purchase date;

- reduce the percentage and principal amount of the outstanding debt securities,
  the consent of whose holders is required in order to take certain actions;

- change any of our obligations to maintain an office or agency in the places
  and for the purposes required by the indenture; or

- modify any of the above provisions.

     The holders of at least a majority in aggregate principal amount of debt
securities of any series may, on behalf of the holders of all debt securities of
that series, waive our compliance certain restrictive provisions of the
indenture. The holders of not less than a

                                        23


majority in aggregate principal amount of debt securities of any series may, on
behalf of all holders of debt securities of that series, waive any past default
and its consequences under the indenture with respect to the debt securities of
that series, except:

- a payment default with respect to debt securities of that series; or

- a default of a covenant or provision of the indenture that cannot be modified
  or amended without the consent of the holder of each debt security of any
  series.

                    CONSOLIDATION, MERGER AND SALE OF ASSETS

     We may, without the consent of the holders of the debt securities,
consolidate or merge with or into, or convey, transfer or lease its properties
and assets substantially as an entirety to, any person that is a corporation,
limited liability company, partnership or trust organized and validly existing
under the laws of any domestic jurisdiction. We may also permit any of those
persons to consolidate with or merge into us or convey, transfer or lease its
properties and assets substantially as an entirety to us, as long as any
successor person assumes our obligations on the debt securities and that after
giving effect to the transaction no event of default under the indenture, and no
event which, after notice or lapse of time or both, would become an event of
default, will have occurred and be continuing, and as long as some other
conditions are met.

                             BOOK-ENTRY SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, we will
issue securities, other than common stock, in the form of one or more book-entry
certificates registered in the name of a depositary or a nominee of a
depositary. Unless otherwise specified in the applicable prospectus supplement,
the depositary will be The Depository Trust Company. We have been informed by
DTC that its nominee will be Cede & Co. Accordingly, Cede is expected to be the
initial registered holder of all securities that are issued in book-entry form.

     No person that acquires a beneficial interest in securities issued in
book-entry form will be entitled to receive a certificate representing those
securities, except as set forth in this prospectus or in the applicable
prospectus supplement. Unless and until definitive securities are issued under
the limited circumstances described below, all references to actions by
beneficial owners of securities issued in book-entry form will refer to actions
taken by DTC upon instructions from its participants, and all references to
payments and notices to beneficial owners will refer to payments and notices to
DTC or Cede, as the registered holder of such securities.

     DTC has informed us that it is:

- a limited purpose trust company organized under New York banking laws;

- a "banking organization" within the meaning of the New York banking laws;

- a member of the Federal Reserve System;

- a "clearing corporation" within the meaning of the New York Uniform Commercial
  Code; and

- a "clearing agency" registered under the Securities Exchange Act.

     DTC has also informed us that it was created to:

- hold securities for "participants"; and

- facilitate the clearance and settlement of securities transactions among
  participants through electronic book-entry, thereby eliminating the need for
  the physical movement of securities certificates.

     Participants have accounts with DTC and include securities brokers and
dealers, banks, trust companies and clearing corporations. Indirect access to
the DTC system also is available to indirect participants such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial

                                        24


relationship with a participant, either directly or indirectly.

     Persons that are not participants or indirect participants but desire to
buy, sell or otherwise transfer ownership of or interests in securities may do
so only through participants and indirect participants. Under the book-entry
system, beneficial owners may experience some delay in receiving payments, as
payments will be forwarded by our agent to Cede, as nominee for DTC. DTC will
forward these payments to its participants, which thereafter will forward them
to indirect participants or beneficial owners. Beneficial owners will not be
recognized by the applicable registrar, transfer agent, trustee or depositary as
registered holders of the securities entitled to the benefits of the
certificate, the indenture or any deposit agreement. Beneficial owners that are
not participants will be permitted to exercise their rights as an owner only
indirectly through participants and, if applicable, indirect participants.

     Under the current rules and regulations affecting DTC, DTC will be required
to make book-entry transfers of securities among participants and to receive and
transmit payments to participants. Participants and indirect participants with
which beneficial owners of securities have accounts are also required by these
rules to make book-entry transfers and receive and transmit such payments on
behalf of their respective account holders.

     Because DTC can act only on behalf of participants, who in turn act only on
behalf of other participants or indirect participants, and on behalf of certain
banks, trust companies and other persons approved by it, the ability of a
beneficial owner of securities issued in book-entry form to pledge those
securities to persons or entities that do not participate in the DTC system may
be limited due to the unavailability of physical certificates for the
securities.

     DTC has advised us that it will take any action permitted to be taken by a
registered holder of any securities under the certificate, the indenture or any
deposit agreement only at the direction of one or more participants to whose
accounts with DTC the securities are credited.

     DTC has further advised us that its management is aware that some computer
applications, systems, and the like for processing data that are dependent upon
calendar dates, including dates before, on, and after January 1, 2000, may
encounter "Year 2000 problems." DTC has informed its participants and other
members of the financial community that it has developed and is implementing a
program so that its computer systems, as they relate to the timely payment of
distributions to securityholders, book-entry deliveries, and settlement of
trades within DTC, continue to function appropriately. This program includes a
technical assessment and a remediation plan, each of which is complete.
Additionally, DTC's plan includes a testing phase, which is expected to be
completed within appropriate time frames.

     However, DTC's ability to perform properly its services is also dependent
upon other parties, including issuers and their agents, as well as DTC's direct
and indirect participants and third party vendors from whom DTC licenses
software and hardware, and third party vendors on whom DTC relies for
information or the provision of services, including telecommunication and
electrical utility service providers, among others. DTC has informed its
participants and other members of the financial community that it is contacting
and will continue to contact third party vendors from whom it acquires services
to impress upon them the importance of such services being Year 2000 compliant
and determine the extent of their efforts for Year 2000 remediation -- and, as
appropriate, testing -- of their services. In addition, DTC is in the process of
developing contingency plans that it considers appropriate.

     According to DTC, the information with respect to DTC has been provided to
its participants and other members of the financial community for informational
purposes only and is not intended to serve as a representation, warranty, or
contract modification of any kind.

     Unless otherwise specified in the applicable prospectus supplement, a book-
entry security will be exchangeable for definitive securities registered in the
names of persons other than DTC or its nominee only if:

- DTC notifies us that it is unwilling or unable to continue as depositary for
  the book-entry security or DTC ceases to be a clearing agency registered under
  the Securities Exchange Act at a time when DTC is required to be so
  registered; or

- we execute and deliver to the applicable registrar, transfer agent, trustee
  and/or depositary an order complying with the requirements of the certificate,
  the indenture or any deposit agreement that the book-entry security will be so
  exchangeable.

Any book-entry security that is exchangeable in accordance with the preceding
sentence will be exchangeable for securities registered in such names as DTC
directs.

     If one of the events described in the immediately preceding paragraph
occurs, DTC is generally required to notify all participants of the availability
through DTC of definitive securities. Upon surrender by DTC of the book-entry
security representing the securities and delivery of instructions for
re-registration, the registrar, transfer agent, trustee or depositary, as the
case may be, will reissue the securities as definitive securities. After
reissuance of the securities, such persons will recognize the beneficial owners
of such definitive securities as registered holders of securities.

     Except as described above:

- a book-entry security may not be transferred except as a whole book-entry
  security by or among DTC, a nominee of DTC and/or a successor depositary
  appointed by us; and

- DTC may not sell, assign or otherwise transfer any beneficial interest in a
  book-entry security unless the beneficial interest is in an amount equal to an
  authorized denomination for the securities evidenced by the book-entry
  security.

     None of Apache, the trustees, any registrar and transfer agent or any
depositary, or any agent of any of them, will have any responsibility or
liability for any aspect of DTC's or any participant's records relating to, or
for payments made on account of, beneficial interests in a book-entry security.

                              PLAN OF DISTRIBUTION

     We may sell the securities through agents, underwriters or dealers, or
directly to one or more purchasers.

     We may designate agents who agree to use their reasonable efforts to
solicit purchases for the period of their appointment or to sell securities on a
continuing basis.

     If we use underwriters for a sale of securities, the underwriters will
acquire the securities for their own account. The underwriters may resell the
securities in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.
The obligations of the underwriters to purchase the securities will be subject
to the conditions set forth in the applicable underwriting agreement. The
underwriters will be obligated to purchase all the securities of the series
offered if any of the securities of that series are purchased. Any initial
public offering price and any discounts or concessions allowed or re-allowed or
paid to dealers may be changed from time to time.

     We may also sell securities directly to one or more purchasers without
using underwriters or agents.

     Underwriters, dealers and agents that participate in the distribution of
the securities may be underwriters as defined in the Securities Act and any
discounts or commissions they receive from us and any profit on their resale of
the securities may be treated as underwriting discounts and commissions under
the Securities Act. The applicable prospectus supplement will identify any
underwriters, dealers or agents and will describe their compensation. We may
have
                                        26


agreements with the underwriters, dealers and agents to indemnify them against
certain civil liabilities, including liabilities under the Securities Act.
Underwriters, dealers and agents may engage in transactions with or perform
services for us or our subsidiaries in the ordinary course of their businesses.

                   TRADING MARKETS AND LISTING OF SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, each
class or series of securities will be a new issue with no established trading
market, other than the common stock, which is listed on the New York Stock
Exchange and the Chicago Stock Exchange. We may elect to list any other class or
series of securities on any exchange, but we are not obligated to do so. It is
possible that one or more underwriters may make a market in a class or series of
securities, but the underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. We cannot give any
assurance as to the liquidity of the trading market for any of the securities.

                            STABILIZATION ACTIVITIES

     Any underwriter may engage in over-allotment, stabilizing transactions,
short-covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act. Over-allotment involves sales in excess of
the offering size, which create a short position. Stabilizing transactions
permit bids to purchase the underlying security so long as the stabilizing bids
do not exceed a specified maximum. Short-covering transactions involve purchases
of the securities in the open market after the distribution is completed to
cover short positions. Penalty bids permit the underwriters to reclaim a selling
concession from a dealer when the securities originally sold by the dealer are
purchased in a covering transaction to cover short positions. Those activities
may cause the price of the securities to be higher than it would otherwise be.
If commenced, the underwriters may discontinue any of the activities at any
time.

                                 LEGAL MATTERS

     The legality of the securities will be passed upon for Apache by its Vice
President and General Counsel, Z. S. Kobiashvili. As of the date of this
prospectus, Mr. Kobiashvili owns 1,990 shares of Apache common stock through
Apache's 401(k) savings plan, holds employee stock options to purchase 45,700
shares of Apache common stock, of which options to purchase 21,200 shares are
currently exercisable, and holds a conditional grant under Apache's 1996 share
Price Appreciation Plan relating to 18,900 shares of Apache common stock, none
of which is vested. In addition, other customary legal matters relating to the
offering of the securities, including matters relating to our due incorporation,
legal existence and authorized capitalization, will be passed upon for Apache by
Mr. Kobiashvili or Mayor, Day, Caldwell & Keeton, L.L.P., Houston, Texas.
