                                    SUMMARY

     This summary highlights information from this prospectus supplement and the
accompanying prospectus, but does not contain all information that is important
to you. This prospectus supplement and the accompanying prospectus include
specific terms of the offering of the notes and information about our business
and our financial data. We encourage you to read this prospectus supplement and
the accompanying prospectus in their entirety before making an investment
decision.

     In this prospectus supplement, the terms "Anadarko," "we," "us" and "our"
generally mean Anadarko Petroleum Corporation, a Delaware corporation, and its
subsidiaries.

                                    ANADARKO

     Anadarko Petroleum Corporation is one of the world's largest independent
oil and gas exploration and production companies, with 2.3 billion barrels of
oil equivalent of proved reserves. Our major areas of operations are located in
the United States, primarily in Texas, Louisiana, the mid-continent and Rocky
Mountain regions, Alaska and in the shallow and deep waters of the Gulf of
Mexico, as well as in Canada and Algeria. We are also active in Venezuela,
Qatar, Australia, Oman, Tunisia, Congo and Gabon. We also own and operate gas
gathering systems in our core producing areas. In addition, we engage in the
hard minerals business through non-operated joint venture and royalty
arrangements in several coal, industrial minerals and trona (natural soda ash)
mines located on lands within and adjacent to our Land Grant holdings primarily
in Wyoming, Colorado and Utah.

     Our corporate headquarters are located at 17001 Northchase Drive, Houston,
Texas 77060-2141. Our telephone number is (281) 875-1101.

                              RECENT DEVELOPMENTS

     On January 31, 2002, we announced financial results for the fourth quarter
and full year 2001 and operating results from exploration and development
drilling activity for the full year. We achieved our operating goals of
double-digit growth in oil and gas production and in proved reserves.

     Fourth Quarter 2001. For the fourth quarter of 2001, we reported net income
available to common shareholders of $108 million, or 41 cents per share
(diluted), compared with earnings of $454 million, or $1.75 per share (diluted)
in the fourth quarter of 2000. The decrease in earnings primarily reflects
sharply lower commodity prices.

     Cash flow from operations before changes in assets and liabilities for the
fourth quarter of 2001 totaled $528 million, compared with $931 million in the
year-earlier period. Fourth quarter 2001 sales volumes were 49 million barrels
of oil equivalent (BOE), which is 9 percent above the fourth quarter of 2000.

     Full Year 2001. For the full year 2001, we reported a net loss of $188
million, or 75 cents per share (diluted), compared with earnings of $796
million, or $4.16 per share (diluted) in the previous year. Results for both
2001 and 2000 include the effect of non-cash property impairments. Stated
without the impairments, earnings in 2001 were $1.39 billion, or $5.25 per share
(diluted), compared with $828 million, or $4.32 per share (diluted) in 2000.

     Cash flow from operations before changes in assets and liabilities for 2001
totaled $3.43 billion, compared with $1.88 billion for the prior year.

     Total natural gas, crude oil and natural gas liquids (NGLs) sales volumes
for 2001 were 199 million BOE, compared with 112 million BOE for 2000, a 78
percent increase. This increase was due in part to the acquisitions of UPR in
mid-2000 and Berkley Petroleum in early 2001, as well as increased production
from the company's operations in Alaska, the Gulf of Mexico, East Texas and
Canada.

                                       S-1


     Reserve Replacement. Our worldwide reserve replacement rate from all
sources was equal to 221 percent of annual production. That figure includes the
effect of additions from drilling, from producing property acquisitions and
divestitures, as well as downward revisions to prior estimates, mostly due to
low year-end prices. Excluding acquisitions and divestitures, we replaced 173
percent of 2001 production. Significant reserves were added through drilling in
the U.S., Canada and Algeria. In the U.S., we achieved a 161 percent reserve
replacement rate in 2001.

     Our five-year U.S. replacement rate for 1997-2001 was 360 percent of
production, or 195 percent excluding acquisitions. Our U.S. replacement rate
again exceeded the industry's five-year U.S. average of 109 percent, as reported
by the U.S. Department of Energy (DOE) for 1996-2000. (DOE data for the latest
five-year period are not yet available.) Our five-year average worldwide reserve
replacement rate from all sources was 476 percent for the period 1997-2001.

     Proved Reserves. We achieved a 12 percent increase in proved reserves,
growing to 2.3 billion BOE at year-end 2001, compared with 2.06 billion BOE at
year-end 2000. This is the 20th consecutive year we have more than replaced our
annual production with proved reserves.

     - Worldwide -- Our proved reserves are balanced between crude oil,
       condensate and liquids (49 percent) and natural gas (51 percent). Proved
       reserves of crude oil, condensate and NGLs totaled 1.13 billion barrels,
       up from 1.05 billion barrels the previous year. Proved natural gas
       reserves at year-end 2001 -- of which 98 percent are located in the U.S.
       and Canada -- totaled 7.03 trillion cubic feet (Tcf), up from 6.09 Tcf in
       2000.

     - U.S. -- Domestic proved reserves were 1.41 billion BOE at year-end 2001,
       or 61 percent of total reserves, compared with 1.33 billion BOE in 2000,
       or 64 percent of total reserves.

     - Canada -- We had 315 million BOE of Canadian proved reserves at year-end
       2001, compared with 220 million BOE the prior year, largely reflecting
       the March 2001 acquisition of Berkley Petroleum.

     - Algeria -- Proved oil reserves in Algeria increased by 6 percent to 387
       million barrels at year-end 2001, compared with 364 million barrels at
       year-end 2000.

     - Acquisitions and Divestitures -- Acquisitions of producing properties,
       principally the Berkley properties in Canada and the Gulfstream
       properties in the Middle East, added 157 million BOE of proved reserves
       for the year. Divestitures, mainly consisting of our properties in
       Guatemala, totaled 60 million BOE.

     Finding Costs. Our total worldwide finding costs for proved reserves were
$8.53 per BOE in 2001, which reflects all costs of additions from drilling and
property acquisitions and the effect of downward reserve revisions.

     Finding costs were higher in 2001 because of increased oil field service
costs early in the year, increased exploration drilling activity in the second
half of 2001 and costs to bring proved undeveloped reserves on production, which
enabled us to increase sales and returns during a period of high prices. Finding
costs also were affected by downward reserve revisions, largely due to lower
year-end commodity prices.

     Proved reserves of 157 million BOE added through property acquisitions were
acquired at an average price of $7.93 per BOE.

Covenants.....................   We will issue the notes under an indenture
                                 containing covenants for your benefit. These
                                 covenants restrict our ability to take certain
                                 actions, including, but not limited to, the
                                 creation of liens securing indebtedness. Please
                                 read "Description of Debt Securities -- Senior
                                 Debt Securities Limitations on Liens" in the
                                 accompanying prospectus.

Use of Proceeds...............   We intend to use the net proceeds of
                                 approximately $643 million to pay down
                                 floating-rate debt. As of February 19, 2002,
                                 the average interest rate on total
                                 floating-rate debt, which had original
                                 maturities ranging from overnight to 35 days,
                                 was 2.27% per year.

Absence of Public Markets for
the Notes.....................   There is no existing market for the notes. We
                                 cannot provide any assurance about:

                                 - the liquidity of any markets that may develop
                                   for the notes;

                                 - your ability to sell your notes; or

                                 - the prices at which you will be able to sell
                                   your notes.

                                       S-3


                                 Future trading prices of the notes will depend
                                 on many factors, including:

                                 - prevailing interest rates;

                                 - our operating results;

                                 - ratings of the notes; and

                                 - the market for similar securities.

                                 The underwriters have advised us that they
                                 currently intend to make a market in the notes
                                 after completion of the offering. They do not,
                                 however, have any obligation to do so, and they
                                 may discontinue any market-making activities at
                                 any time without any notice. We do not intend
                                 to apply for listing of the notes on any
                                 securities exchange or for quotation of the
                                 notes in any automated dealer quotation system.

Risk Factors..................   We urge you to carefully read the "Risk
                                 Factors" section on page 6 of the accompanying
                                 prospectus before you make any investment

                                USE OF PROCEEDS

     We expect to receive net proceeds from the sale of the notes of
approximately $643 million, after deducting underwriting discounts, commissions
and offering expenses. We intend to use the net proceeds to pay down
floating-rate debt. As of February 19, 2002, the average interest rate on total
floating-rate debt, which had original maturities ranging from overnight to 35
days, was 2.27% per year.

                                 CAPITALIZATION

     The following table sets forth a summary of the capitalization of Anadarko
at September 30, 2001 and as adjusted to reflect the issuance of $650 million of
notes and our application of the net proceeds we will receive from the issuance
to pay down floating rate debt. This table should be read in conjunction with

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

     The following table sets forth our consolidated ratios of earnings to fixed
charges and earnings to combined fixed charges and preferred stock dividends for
the periods shown:



                                                 YEARS ENDED DECEMBER 31,

Earnings/Combined Fixed Charges and
  Preferred Stock Dividends................  3.34   3.04   0.05   1.53   6.80            --


     We issued preferred stock in May 1998. No shares of preferred stock were
outstanding during any of the periods prior to May 1998.

     As a result of our net loss for the nine months ended September 30, 2001,
our earnings did not cover fixed charges by $700 million and did not cover
combined fixed charges and preferred stock dividends by $709 million. In 1998,
our earnings did not cover fixed charges by $90 million and did not cover
combined fixed charges and preferred stock dividends by $101 million.

     The ratios were computed by dividing earnings by either fixed charges or
combined fixed charges and preferred stock dividends. For this purpose, earnings
include income before income taxes and fixed charges. Fixed charges include
interest and amortization of debt expenses and the estimated interest component
of rentals. Preferred stock dividends are adjusted to reflect the amount of
pre-tax earnings required for payment.

                              DESCRIPTION OF NOTES

     The following description of the notes supplements, and to the extent
inconsistent, replaces, the description of the general terms and provisions of
the senior debt securities set forth in the accompanying prospectus. The notes
are to be issued as a separate series of senior debt securities under an
indenture dated as of March 9, 2001, between Anadarko and The Bank of New York,
as Trustee, which is more fully described in the accompanying prospectus. We
will issue the notes pursuant to a resolution of the Board of Directors and an
officers' certificate setting forth specific terms applicable to the notes. The
statements under this caption relating to the notes, the senior indenture and
the board resolution are brief summaries only, are not complete and are subject
to, and are qualified in their entirety by reference to, all of the provisions
of the indenture and the notes, forms of which are available from us.
Capitalized terms used herein have the meaning set forth in the accompanying
prospectus or the indenture.

GENERAL

     The notes initially will be limited to $650,000,000 in aggregate principal
amount and will mature on March 1, 2007. The notes will bear interest from
February 22, 2002, at 5 3/8% per year. Interest will be payable semiannually on
March 1 and September 1 of each year, commencing September 1, 2002, to the
holders of record of the notes at the close of business on the preceding
February 15 or August 15, whether or not such day is a business day. All
payments of interest and principal will be payable in United States dollars. The
notes will be issued only in book-entry form. Please read "Description of Debt
Securities -- Global Securities" of the accompanying prospectus.

     The notes will be senior unsecured obligations and will rank equally in
right of payment to all our other senior unsecured indebtedness. The notes will
rank senior to any future subordinated indebtedness and will be effectively
junior to future secured indebtedness, if any, and to all existing and future
indebtedness and other liabilities of our subsidiaries. As of September 30,
2001, our subsidiaries had approximately $3.1 billion of indebtedness. As of
September 30, 2001, as adjusted to give effect to the issuance of the notes and
the anticipated use of proceeds therefrom, we would have had an aggregate of
$4.72 billion of consolidated indebtedness.

REDEMPTION

     The notes will be redeemable, at our option, at any time in whole or from
time to time in part, upon not less than 15 and not more than 60 days' notice as
provided in the indenture, on any date prior to maturity at a price equal to
100% of the principal amount of the notes being redeemed plus accrued interest
to the redemption date (subject to the right of holders of record on the
relevant record date to receive interest due on an interest payment date that is
on or prior to the redemption date), plus a make-whole premium, if any is
required to be paid. The redemption price will never be less than 100% of the
principal amount of such series of notes plus accrued interest to the redemption
date.

     The amount of the make-whole premium with respect to any note (or portion
of a note) to be redeemed will be equal to the excess, if any, of:

     (i) the sum of the present values, calculated as of the redemption date,
of:

          (A) each interest payment that, but for the redemption, would have
     been payable on the note (or portion of a note) being redeemed on each
     interest payment date occurring after the redemption date (excluding any
     accrued interest for the period before the redemption date); and

          (B) the principal amount that, but for the redemption, would have been
     payable at the final maturity of the note (or portion of a note) being
     redeemed;

     over

                                       S-7


     (ii) the principal amount of the note (or portion of a note) being
redeemed.

     The present values of interest and principal payments referred to in clause
(i) above will be determined in accordance with generally accepted principles of
financial analysis. Those present values will be calculated by discounting the
amount of each payment of interest or principal from the date that each payment
would have been payable, but for the redemption, to the redemption date at a
discount rate equal to the Treasury Yield (as defined below) plus 15 basis
points.

     The make-whole premium will be calculated by an independent investment
banking institution of national standing appointed by us, provided that if we
fail to make such appointment at least 15 business days prior to the redemption
date, or if the institution so appointed is unwilling or unable to make the
calculation, such calculation will be made by Credit Suisse First Boston
Corporation or, if that firm is unwilling or unable to make the calculation, by
an independent investment banking institution of national standing appointed by
the Trustee.

     For purposes of determining the make-whole premium, "Treasury Yield" means
a rate of interest per annum equal to the weekly average yield to maturity of
United States Treasury Notes that have a constant maturity that corresponds to
the remaining term to maturity of the notes, calculated to the nearest 1/12 of a
year. The Treasury Yield will be determined as of the third business day
immediately before the applicable redemption date.

     The weekly average yields of United States Treasury Notes will be
determined by referring to the most recent statistical release published by the
Federal Reserve Bank of New York and designated "H.15 (519) Selected Interest
Rates" or any successor release. If the H.15 Statistical Release contains a
weekly average yield for United States Treasury Notes having a constant maturity
that is the same as the remaining term, then the Treasury Yield will be equal to
that weekly average yield. In all other cases, the Treasury Yield will be
calculated by interpolation, on a straight-line basis, between the weekly
average yields on the United States Treasury Notes that have a constant maturity
closest to and greater than the remaining term and the United States Treasury
Notes that have a constant maturity closest to and less than the remaining term
(in each case as set forth in the H.15 Statistical Release). Any weekly average
yields as calculated by interpolation will be rounded to the nearest 1/100th of
1% with any figure of 1/200 or above being rounded upward. If weekly average
yields for United States Treasury Notes are not available in the H.15
Statistical Release or otherwise, then the Treasury Yield will be calculated by
interpolation of comparable rates selected by the independent investment banker.

     If less than all of the notes are to be redeemed, the Trustee will select
the notes to be redeemed by a method that the Trustee deems fair and
appropriate. The Trustee may select for redemption notes and portions of notes
in amounts of whole multiples of $1,000.

     The notes are not subject to a sinking fund.

ADDITIONAL NOTES

     We may, without the consent of the holders of the notes, create and issue
additional notes of the series ranking equally with the notes in all respects,
including having the same CUSIP number, so that such additional notes shall be
consolidated and form a single series with the notes and shall have the same
terms as to status, redemption or otherwise as the notes. No additional notes
may be issued if an event of default under the indenture has occurred and is
continuing with respect to the notes.

BOOK-ENTRY SYSTEMS

     The notes will be issued in fully registered form initially in the name of
Cede & Co., as nominee of The Depository Trust Company ("DTC"). One or more
fully registered certificates will be issued as global notes for the notes in
the aggregate principal amount of the notes. Global notes will be deposited with
DTC and may not be transferred except as a whole by DTC to a nominee of

                                       S-8


DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any
nominee to a successor of DTC or a nominee of such successor.

     DTC has advised us and the underwriters of the following matters. The
information in this section concerning DTC and DTC's book-entry system has been
obtained from sources that we believe to be reliable (including DTC), but we
take no responsibility for the accuracy thereof.

     DTC is:

     - a limited-purpose trust company organized under the New York Banking Law;

     - a "banking organization" under the New York Banking Law;

     - 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 pursuant to the provisions of Section 17A
       of the Securities Exchange Act of 1934, as amended.

     DTC holds securities that its participants deposit with DTC. DTC also
facilitates the clearance and settlement among participants of securities
transactions, such as transfers and pledges, in deposited securities, through
electronic computerized book-entry changes in participants' accounts, thereby
eliminating the need for physical movement of securities certificates.
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations, and certain other organizations. DTC is owned by a number
of its participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others such as securities brokers and
dealers, banks, and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly, as an indirect
participant. The rules applicable to DTC and its participants are on file with
the Securities and Exchange Commission.

     Purchases of notes under the DTC system must be made by or through
participants, which will receive a credit for the notes on DTC's records. The
ownership interest of each actual purchaser of notes ("Beneficial Owner") is in
turn to be recorded on the participants' and indirect participants' records.
Beneficial Owners will not receive written confirmation from DTC of their
purchase, but Beneficial Owners are expected to receive written confirmations
providing details of the transaction, as well as periodic statements of their
holdings, from the participants and indirect participants through which the
Beneficial Owner entered into the transaction. Transfers of ownership interests
in the notes are to be accomplished by entries made on the books of participants
acting on behalf of Beneficial Owners. Beneficial Owners will not receive
certificates representing their ownership interests in the notes, except in the
event that use of the book-entry system for the notes is discontinued.

     To facilitate subsequent transfers, all notes deposited by participants
with DTC are registered in the name of DTC's partnership nominee, Cede & Co. The
deposit of notes with DTC and their registration in the name of Cede & Co.
effect no change in beneficial ownership. DTC has no knowledge of the actual
Beneficial Owners of the notes; DTC's records reflect only the identity of the
participants to whose accounts such notes are credited, which may or may not be
the Beneficial Owners. The participants will remain responsible for keeping
account of their holdings on behalf of their customers.

     Conveyance of notices and other communications by DTC to participants, by
participants to indirect participants, and by participants and indirect
participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.

                                       S-9


     Redemption notices shall be sent to DTC. If less than all of the notes are
being redeemed, DTC's practice is to determine by lot the amount of the interest
of each participant in such issue to be redeemed.

     Neither DTC nor Cede & Co. will consent or vote with respect to the global
notes. Under its usual procedures, DTC mails an omnibus proxy to the issuer as
soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s
consenting or voting rights to those participants to whose accounts the notes
are credited on the record date (identified in the listing attached to the
Omnibus Proxy).

     Principal and interest payments on the global notes will be made to Cede &
Co., as nominee of DTC. We expect that DTC, upon receipt of any payment of
principal, premium or interest in respect of a global note, will credit
participants' accounts immediately with payments in amounts proportionate to
their respective interests in the principal amount of such global note as shown
on DTC's records. We also expect that payments by participants to Beneficial
Owners will be governed by standing instructions and customary practices, as is
the case with securities held for the accounts of customers in bearer form or
registered in "street name," and will be the responsibility of such participant
and not of DTC, us or the Trustee, subject to any statutory or regulatory
requirements as may be in effect from time to time.

     DTC may discontinue providing its service as securities depositary with
respect to the notes at any time by giving reasonable notice to us or the
Trustee. In addition, we may decide to discontinue use of the system of
book-entry transfers through DTC (or a successor securities depositary). Under
such circumstances, if a successor securities depositary is not obtained,
certificates representing the notes in fully registered form are required to be
printed and delivered to Beneficial Owners.

     Neither we, the Trustee nor the underwriters will have any responsibility
or obligation to participants, or the persons for whom they act as nominees,
with respect to the accuracy of the records of DTC, its nominee or any
participant with respect to any ownership interest in the notes, or payments to,
or the providing of notice to participants or Beneficial Owners.

     The notes will trade in DTC's Same-Day Funds Settlement System and
secondary market trading activity in the notes will, therefore, settle in
immediately available funds. We will make all applicable payments of principal,
premium (if any) and interest on the notes issued as global notes in immediately
available funds.

     For other terms of the notes, please read "Description of Debt Securities"
in the accompanying prospectus.

                                  UNDERWRITING

     Subject to the terms and conditions stated in the underwriting agreement
dated February 19, 2002, each underwriter named below has severally agreed to
purchase, and Anadarko has agreed to sell to such underwriter, the principal
amount of notes set forth opposite the name of such underwriter:



                                                                 PRINCIPAL

                                                               ------------
          Total.............................................   $650,000,000
                                                               ============


     In the underwriting agreement, the underwriters have agreed, subject to the
terms and conditions set forth therein, to purchase all of the notes offered
hereby if any of the notes are purchased.

     The underwriters propose initially to offer the notes to the public at the
offering prices set forth on the cover page of this prospectus supplement, and
to certain dealers at such price less a selling concession not in excess of
0.35% of the principal amount of the notes. The underwriters may allow, and such
dealers may reallow, a discount not in excess of 0.25% of the principal amount
of the notes to certain other dealers. After the initial public offering, the
public offering prices, concessions and discounts may be changed.

     In the ordinary course of business, the underwriters and their affiliates
have in the past and may in the future provide investment banking, general
financing and banking or other services to us and our affiliates. Affiliates of
each of the underwriters are lenders under our existing credit facilities. We
currently have an aggregate of $62.9 million of indebtedness outstanding with
all of the underwriters under these credit facilities. In addition, we have
$52.5 million outstanding under a money market line of credit with an affiliate
of J.P. Morgan Securities Inc.

     We have agreed to indemnify the underwriters against certain civil
liabilities, including liabilities under the Securities Act of 1933, as amended,
and to contribute to payments which the underwriters might be required to make
in that respect.

     In connection with the offering and sale of the notes, the underwriters may
engage in stabilizing transactions, overallotment, syndicate covering
transactions and penalty bids in accordance with Regulation M under the
Securities Exchange Act of 1934, as amended.

     - Stabilizing transactions permit bids to purchase the notes in the open
       market for the purpose of pegging, fixing or maintaining the price of the
       notes so long as the stabilizing bids do not exceed a specified maximum.

     - Overallotment involves sales in excess of the offering size, which
       creates a short position for the underwriters.

     - Syndicate covering transactions involve purchases of the notes in the
       open market after the distribution has been completed in order to cover
       syndicate short positions.

     - Penalty bids permit the underwriters to reclaim a selling concession from
       a broker/dealer when the notes originally sold by such broker/dealer are
       purchased in a stabilizing or covering transactions to cover short
       positions.

These stabilizing transactions, syndicate covering transactions and penalty bids
may have the effect of raising or maintaining the market price of the notes or
preventing or retarding a decline in the market price of the notes. As a result,
the price of the notes may be higher than the price that

                                       S-11


might otherwise exist in the open market. These activities, if commenced, may be
discontinued at any time.

     Some of the underwriters may make the securities available for distribution
on the Internet through a proprietary Web site and/or a third-party system
operated by Market Axess Inc., an Internet-based communications technology
provider. Market Axess Inc. would provide the system as a conduit for
communications between the underwriters and their respective customers and would
not be a party to any transactions. Market Axess Inc., a registered
broker-dealer, would receive compensation from the underwriters based on
transactions the underwriters conduct through the system. The underwriters would
make the securities available to their respective customers through the Internet
distributions, whether made through a proprietary or third-party system, on the
same terms as distributions made through other channels.

     The notes are a new series of securities with no established trading
market. We do not intend to apply for listing of the notes on any securities
exchange or for quotation of the notes in any automated dealer quotation system.
The underwriters have advised us that they intend to make a market in each
series of notes, but the underwriters are under no obligation to do so and such
market-making activities may be terminated at any time without notice.
Therefore, no assurance can be given as to the liquidity of, or the trading
market for, the notes.

     We estimate that we will spend $100,000 for fees and expenses associated
with the offering of the notes.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the notes in Canada is being made only on a private
placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of notes are made. Any resale of the notes in Canada must be made under
applicable securities laws, which will vary depending on the relevant
jurisdiction, and which may require resales to be made under available statutory
exemptions or under a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the notes.

REPRESENTATIONS OF PURCHASERS

     By purchasing notes in Canada and accepting a purchase confirmation a
purchaser is representing to us and the dealer from whom the purchase
confirmation is received that

     - the purchaser is entitled under applicable provincial securities laws to
       purchase the notes, without the benefit of a prospectus qualified under
       those securities laws,

     - where required by law, the purchaser is purchasing as principal and not
       as agent, and

     - the purchaser has reviewed the text above under Resale Restrictions.

RIGHTS OF ACTION -- ONTARIO PURCHASERS ONLY

     Under Ontario securities legislation, a purchaser who purchases a security
offered by this prospectus as supplemented during the period of distribution
will have a statutory right of action for damages, or while still the owner of
the notes, for rescission against us in the event that this prospectus as
supplemented contains a misrepresentation. A purchaser will be deemed to have
relied on the misrepresentation. The right of action for damages is exercisable
not later than the earlier of 180 days from the date the purchaser first had
knowledge of the facts giving rise to the cause of action and three years from
the date on which payment is made for the notes. The right of action for
rescission is exercisable not later than 180 days from the date on which payment
is made
                                       S-12


for the notes. If a purchaser elects to exercise the right of action for
rescission, the purchaser will have no right of action for damages against us.
In no case will the amount recoverable in any action exceed the price at which
the notes were offered to the purchaser and if the purchaser is shown to have
purchased the securities with knowledge of the misrepresentation, we will have
no liability. In the case of an action for damages, we will not be liable for
all or any portion of the damages that are proven to not represent the
depreciation in value of the notes as a result of the misrepresentation relied
upon. These rights are in addition to, and without derogation from, any other
rights or remedies available at law to an Ontario purchaser. The foregoing is a
summary of the rights available to an Ontario purchaser. Ontario purchasers
should refer to the complete text of the relevant statutory provisions.

ENFORCEMENT OF LEGAL RIGHTS

     All of our directors and officers as well as the experts named herein may
be located outside of Canada and, as a result, it may not be possible for
Canadian purchasers to effect service of process within Canada upon us or those
persons. All or a substantial portion of our assets and the assets of those
persons may be located outside of Canada and, as a result, it may not be
possible to satisfy a judgment against us or those persons in Canada or to
enforce a judgment obtained in Canadian courts against us or those persons
outside of Canada.

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of notes should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the notes in
their particular circumstances and about the eligibility of the notes for
investment by the purchaser under relevant Canadian legislation.

RELATIONSHIP WITH AFFILIATES OF THE UNDERWRITERS

     We are in compliance with the terms of the indebtedness owed by us to
affiliates of each of the underwriters. The decision of each of the underwriters
to distribute the notes was not influenced by their respective affiliates that
are our lenders and those affiliates had no involvement in determining whether
or when to distribute the notes under this offering or the terms of this
offering. Each of the underwriters will not receive any benefit from this
offering other than the underwriting discounts and commissions paid by us.

                                 LEGAL MATTERS

     The legality of the notes will be passed upon for us by Andrews & Kurth
Mayor, Day, Caldwell & Keeton, L.L.P., Houston, Texas. Certain legal matters
with respect to the notes will be passed upon for the underwriters by Hughes
Hubbard & Reed LLP, New York, New York.

     The consolidated financial statements of Anadarko and its subsidiaries as
of December 31, 2000 and 1999 and for each of the years in the three-year period

public accountants, as indicated in their reports with respect thereto.

     With respect to the unaudited interim financial information of Union
Pacific Resources Group Inc. and its subsidiaries for the quarter ended March
31, 2000 incorporated by reference in the accompanying prospectus, Arthur
Andersen LLP has applied limited procedures in accordance with professional
standards for a review of that information. However, their separate report
thereon states that they did not audit and they do not express an opinion on
that interim financial information. Accordingly, the degree of reliance on their
report on that information should be restricted in light of the limited nature
of the review procedures applied.

     Certain excerpts from the consolidated financial statements of Union
Pacific Resources Group Inc. and its subsidiaries as of and for the year ended
December 31, 1997 incorporated by reference in the accompanying prospectus have

                             ABOUT THIS PROSPECTUS

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

     This prospectus is part of a registration statement that Anadarko, Anadarko
Petroleum Capital Trust I, Anadarko Petroleum Capital Trust II and Anadarko
Petroleum Capital Trust III filed with the Securities and Exchange Commission
(SEC) utilizing a "shelf " registration process. Under this shelf process, we
may sell Debt Securities, Preferred Stock, Depositary Shares, Common Stock,
Warrants, Purchase Agreements and Purchase Units and the Trusts may issue Trust
Preferred Securities in one or more offerings up to a total dollar amount of
$1,000,000,000.

     This prospectus provides you with a general description of the securities
we and the Trusts may offer. Each time securities are sold, a prospectus
supplement will provide specific information about the terms of that offering.
The prospectus supplement may also add, update or change information contained
in this prospectus. If there is any inconsistency between the information in
this prospectus and any prospectus supplement, you should rely on the
information in the prospectus supplement. The registration statement filed with
the SEC includes exhibits that provide more details about the matters discussed
in this prospectus. You should read this prospectus, the related exhibits filed
with the SEC and any prospectus supplement, together with the additional
information described under the heading "Where You Can Find More Information
About Anadarko."

     In this prospectus, the terms "Anadarko," "company," "we," "us" and "our"
generally mean Anadarko Petroleum Corporation, a Delaware corporation, and its
consolidated subsidiaries.

     Unless otherwise indicated, all dollar amounts in this prospectus are
expressed in U.S. dollars.

                         ANADARKO PETROLEUM CORPORATION

     Anadarko Petroleum Corporation is one of the world's largest independent
oil and gas exploration and production companies, with two billion barrels of
oil equivalent (BOE) of proved reserves. The Company's major areas of operations
are located in the United States, primarily in Texas, Louisiana, the
Mid-Continent and Rocky Mountain regions, Alaska and in the shallow and deep
waters of the Gulf of Mexico, as well as in Algeria, Canada, Guatemala,
Venezuela and other international areas. Exploration activity is underway in
Tunisia, West Africa, the former Soviet Republic of Georgia and the North
Atlantic Margin. The Company also owns and operates gas gathering systems in its
U.S. core producing areas. In addition, the Company engages in the hard minerals
business through non-operated joint venture and royalty arrangements in several
coal, industrial minerals and trona (natural soda ash) mines located on lands
within and adjacent to its Land Grant holdings in Wyoming.

     On July 14, 2000, a subsidiary of the Company merged with and into Union
Pacific Resources Group Inc (UPR). As a result UPR became a wholly owned
subsidiary of the Company and stockholders of UPR were entitled to receive
Anadarko common shares in exchange for UPR common shares. The merger was treated
as a tax-free reorganization and accounted for as a purchase business
combination.

     The foregoing information about Anadarko and its business is only a general
summary and is not intended to be comprehensive. For additional information
about Anadarko and its business, you should refer to the information described
under the caption "Where You Can Find More Information about Anadarko."

                                   THE TRUSTS

     Anadarko formed each Trust as a statutory business trust under Delaware
law. Each Trust's business is defined in a declaration of trust executed by
Anadarko, as sponsor, and The Bank of New York (Delaware), as Delaware trustee.
Each declaration of trust will be amended when trust preferred securities are
issued under it and will be in substantially the form filed as an exhibit to

                                        3


the registration statement, of which this prospectus is a part. An amended
declaration of trust is called a "trust agreement" in this prospectus.

     The trust preferred securities and the trust common securities of each
Trust represent undivided beneficial interests in the assets of that Trust. The
trust preferred securities and the trust common securities together are
sometimes called the "trust securities" in this prospectus.

     Anadarko owns, directly or indirectly, all the common securities of each
Trust, which have an aggregate liquidation value equal to at least 3% of the
total capital of each Trust. The trust preferred securities of each Trust will
represent the remaining percentage of each trust's total capitalization. The
trust common securities will have terms substantially equal to, and will rank
equal in priority of payment with, the trust preferred securities. However, if
Anadarko defaults on the subordinated debt securities owned by a trust or
another event of default under the applicable trust agreement occurs, then, so
long as the default continues, cash distributions and liquidation, redemption
and other amounts payable or deliverable on the trust securities of that Trust
must be paid or delivered to holders of the trust preferred securities of that
Trust before the holders of that Trust's common securities. No Trust may borrow
money, issue debt, exchange mortgages or pledge any of its assets. The trust
preferred securities will be guaranteed by Anadarko as described in this
prospectus and the applicable prospectus supplement.

     Each Trust exists for the exclusive purpose of:

     - issuing the trust common and trust preferred securities representing
       undivided beneficial interests in the assets of the Trust;

     - investing the gross proceeds of the trust common and trust preferred
       securities in Anadarko's subordinated debt securities; and

     - engaging only in those other activities necessary or incidental thereto.

     Anadarko, as holder of the trust common securities of each Trust, will
appoint the trustees of that Trust. Unless otherwise specified in the applicable
prospectus supplement, the five trustees that will conduct each Trust's business
and affairs will consist of:

     - three of Anadarko's employees, officers or affiliates, as administrative
       trustees;

     - The Bank of New York (Delaware), an affiliate of The Bank of New York, as
       property trustee; and

     - The Bank of New York (Delaware), as Delaware trustee.

     The Bank of New York also serves as the indenture trustee for purposes of
compliance with the provisions of the Trust Indenture Act of 1939, the guaranty
trustee under Anadarko's guarantee in favor of the holders of trust preferred
securities and debt trustee under the indenture related to Anadarko's debt
securities. The property trustee holds title to Anadarko's subordinated debt
securities for the benefit of the holders of each Trust's trust common and trust
preferred securities. The property trustee has the power to exercise all rights,
powers and privileges under each indenture as holder of Anadarko's subordinated
debt securities. In addition, the property trustee maintains exclusive control
of a segregated, non-interest bearing bank account to hold all payments made in
respect of Anadarko's subordinated debt securities for the benefit of the
holders of each Trust's trust common and trust preferred securities. The
property trustee makes payments of distributions and payment on liquidation,
redemption and otherwise to the holders of each Trust's trust common and trust
preferred securities out of funds from each Trust's bank account. Anadarko, as a
direct or an indirect holder of all of each Trust's trust common securities, has
the right to appoint, remove or replace any administrative trustee and to
increase or decrease the number of administrative trustees. Anadarko pays all
fees and expenses related to each Trust and each offering of trust common and
trust preferred securities.

     The rights of the holders of each Trust's trust preferred securities,
including economic rights, rights to information and voting rights, will be set
forth in the trust agreement relating to each

                                        4


Trust and in the Delaware Business Trust Act. Each trust agreement, each
indenture and each Anadarko guarantee will also incorporate by reference terms
of the Trust Indenture Act of 1939. Each trust agreement, each indenture and
each Anadarko guarantee will be qualified under the Trust Indenture Act.

     The prospectus supplement relating to the trust preferred securities of a
Trust will provide further information concerning that Trust.

     No separate financial statements of any Trust are included in this
prospectus. Anadarko considers that such statements would not be material to
holders of the trust preferred securities because no Trust has any independent
operations, and the sole purpose of each Trust is investing the proceeds from
the sale of its trust securities in subordinated debt securities of Anadarko.
Anadarko does not expect that any of the Trusts will be filing annual, quarterly
or current reports with the SEC.

     The principal place of business of each Trust will be c/o Anadarko
Petroleum Corporation, 17001 Northchase Drive, Houston, Texas 77060-2141,
telephone (281) 875-1101.

                              ACCOUNTING TREATMENT

     Each Trust will be treated as a subsidiary of Anadarko for financial
reporting purposes. Accordingly, Anadarko's consolidated financial statements
will include the accounts of each Trust. The trust preferred securities, along
with other trust preferred securities that Anadarko guarantees on an equivalent
basis, will be presented as a separate line item in Anadarko's consolidated
balance sheets, entitled "Guaranteed Preferred Beneficial Interests in
Subordinated Notes of Anadarko Petroleum Corporation or Subsidiaries." Anadarko
will record distributions that each Trust pays on the trust preferred securities
as an expense in its consolidated statement of income.

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

     The following table sets forth Anadarko's consolidated ratios of earnings
to fixed charges and earnings to combined fixed charges and preferred stock
dividends for the periods shown:



                                           YEARS ENDED DECEMBER 31,         SEPTEMBER 30
                                       --------------------------------     -------------

Fixed Charges........................  1.24   3.34   3.04   0.05   1.77     1.26    5.53
Combined Fixed Charges and Preferred
  Stock Dividends....................  1.24   3.34   3.04   0.05   1.53     1.08    5.04


     Anadarko issued preferred stock in May 1998. No shares of preferred stock
were outstanding during any of the periods prior to May 1998.

     As a result of Anadarko's net loss in 1998, Anadarko's earnings did not
cover fixed charges by $90 million and did not cover combined fixed charges and
preferred stock dividends by $101 million in 1998. The ratios were computed by
dividing earnings by either fixed charges or combined fixed charges and
preferred stock dividends. For this purpose, earnings include income before
income taxes and fixed charges. Fixed charges include interest and amortization
of debt expenses and the

                                        6


estimated interest component of rentals. Preferred stock dividends are adjusted
to reflect the amount of pre-tax earnings required for payment.

                                USE OF PROCEEDS

     Unless specified otherwise in the applicable prospectus supplement, we
expect to use the net proceeds we receive from the sale of the securities
offered by this prospectus and the accompanying prospectus supplement 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 Trusts will use all proceeds from the sale of trust common and trust
preferred securities to purchase Anadarko debt securities.

                         DESCRIPTION OF DEBT SECURITIES

     The following description sets forth the general terms and provisions that
could apply to the debt securities. Each prospectus supplement will state the
particular terms that actually will apply to the debt securities included in the
supplement.

     The debt securities will be either our senior debt securities or our
subordinated securities. We have issued to date an aggregate of $3.8 billion of
senior securities. We do not have any subordinated securities outstanding at
this time.

     In addition to the following summary, you should refer to the applicable
provisions of the following documents for more detailed information:

     - the senior indenture, and

     - the subordinated indenture.

     Neither indenture limits the aggregate principal amount of debt securities
that we may issue under that indenture. The debt securities may be issued in one
or more series as we may authorize at various times. All debt securities will be
unsecured. The senior securities will have the same rank as all of our other
unsecured and unsubordinated debt. The subordinated securities will be
subordinated to senior indebtedness as described in the "Subordinated
Securities" section. 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:

     - whether the debt securities are senior securities or subordinated
       securities;

     - the title and the limit on the aggregate principal amount of the debt
       securities;

     - the dates on which the debt securities will mature;

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

     - the dates from which interest shall accrue and the dates on which
       interest will be payable;

     - the currencies in which the debt securities are denominated and principal
       and interest may be payable;

     - any redemption or sinking fund terms;

                                        7


     - any event of default or covenant with respect to the debt securities of a
       particular series, if not set forth in this prospectus;

     - whether the debt securities are to be issued, in whole or in part, in the
       form of one or more global securities and the depositary for the global
       securities;

     - whether payments of principal, premium or interest will be free from any
       deduction for taxes, assessments or governmental charges payable by the
       holders;

     - whether the company will pay additional amounts on debt securities held
       by a non-U.S. person for any tax, assessment or governmental charge and,
       if so, whether the company will have the option to redeem such
       securities;

     - if definitive securities may be issued, the conditions under which same
       may be issued;

     - whether the debt securities are convertible into Anadarko common stock;
       and,

     - any other terms of the series, which will not conflict with the terms of
       the applicable indenture.

     We may issue debt securities of any series at various times and we may
reopen any series for further issuances from time to time without notice to
existing holders.

     We will issue the debt securities in fully registered form without coupons.
Unless we specify otherwise in the applicable prospectus supplement, we will
issue debt securities denominated in U.S. dollars in denominations of $1,000 or
multiples of $1,000 for debt securities.

     We will describe special 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.

EXCHANGE, REGISTRATION AND TRANSFER

     Debt securities of any series that are not global securities will be
exchangeable for other debt securities of the same series and of like aggregate
principal amount and tenor in different authorized denominations. In addition,
you may present debt 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. No service charge is required for any transfer or exchange of debt
securities but we may require payment of any taxes and other governmental
charges. 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 applicable trustee as security
registrar for the applicable indenture. We may at any time designate additional
transfer agents with respect to any series of debt securities.

     In the event of any redemption in part, 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 the
       mailing of notice of redemption of debt securities of that series to be
       redeemed and ending at the close of business on the mailing date;

                                        8


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

     For a discussion of restriction on the exchange, registration and transfer
of global securities, see "Global Securities."

PAYMENT AND PAYING AGENTS

     Unless we specify otherwise in the applicable prospectus supplement,
payment of principal, any premium and any interest on debt securities will be
made at the office of the 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 debt 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 issued solely as debt securities.

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. 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 persons that
have accounts with the depositary ("participants"). 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

                                        9


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, any premium on and any 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 for the debt securities, 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 in the global security.

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

MODIFICATION OF THE INDENTURES

     Under each indenture our rights and obligations and the rights of the
holders may be modified with the consent of the holders of at least a majority
in principal amount of the then outstanding debt securities of each series
affected by the modification. None of the following modifications, however, is
effective against any holder without the consent of the holders of all of the
affected outstanding debt securities:

     - changing the maturity, installment or interest rate of any of the debt
       securities;

     - reduce the principal amount of (or premium, if any) or interest on any
       debt security;

     - reduce the amount of principal of an original issue discount security
       payable upon acceleration of maturity;

                                        10


     - changing the conversion provisions of any of the debt securities, or
       subordination provisions of the subordinated indenture, in a manner
       adverse to the holders;

     - change the place or currency of payment of (or premium, if any) or
       interest on any debt security;

     - reducing the percentage required for modifications or waivers of
       compliance with the indentures;

     - impair the right of a holder to institute suit for the enforcement of any
       payment on or with respect to any debt security; or

     - with some exceptions, modifying the provisions for the waiver of
       covenants and defaults and any of the foregoing provisions.

     Any actions we or the trustee may take toward adding to our covenants,
adding events of default or establishing the structure or terms of the debt
securities as permitted by the indentures will not require the approval of any
holder of debt securities. In addition, we or the trustee may cure ambiguities
or inconsistencies in the indentures or make other provisions without the
approval of any holder as long as no holder's interests are materially and
adversely affected.

EVENTS OF DEFAULT, NOTICE AND WAIVER

     "Event of default" when used in an indenture, will mean any of the
following in relation to a series of debt securities:

     - failure to pay interest on any debt security for 60 days after the
       interest becomes due;

     - failure to pay the principal or any premium on any debt security when
       due;

     - failure to deposit any sinking fund payment for 60 days after such
       payment becomes due;

     - failure to perform or breach of any other covenant or warranty in the
       indenture that continues for 90 days after our being given notice from
       the trustee or the holders of at least 25% in principal amount of the
       outstanding debt securities of the series;

     - default in the payment when due of other indebtedness in an aggregate
       principal amount in excess of $25,000,000, causing such indebtedness to
       become due prior to its stated maturity, and such default is not cured
       within 30 days after notice from the trustee or the holders of at least
       5% in principal amount of the outstanding debt securities of the series;

     - a creditor commences involuntary bankruptcy, insolvency or similar
       proceedings against us and we are unable to obtain a stay or dismissal of
       that proceeding within 90 days;

     - we voluntarily seek relief under bankruptcy, insolvency or similar laws
       or we consent to a court entering an order for relief against us under
       those laws; or

     - any other event of default provided for debt securities of that series.

     If any event of default relating to outstanding debt securities of any
series occurs and is continuing, either the trustee or the holders of at least
25% in principal amount of the outstanding debt securities of that series may
declare the principal of all of the outstanding debt securities of such series
to be due and immediately payable.

     The indentures provide that the holders of at least a majority in principal
amount of the outstanding debt securities of any series may direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee, or of exercising any trust or power conferred on the trustee, with
respect to the debt securities of that series. The trustee may act in any way
that is consistent with those directions and may decline to act if any of the
directions is contrary to law or to the indentures or would involve the trustee
in personal liability.

                                        11


     The indentures provide that the holders of at least a majority in principal
amount of the outstanding debt securities of any series may on behalf of the
holders of all of the outstanding debt securities of the series waive any past
default (and its consequences) under the indentures relating to the series,
except a default (a) in the payment of the principal of or any premium on or
interest on any of the debt securities of the series, or (b) with respect to a
covenant or provision of such indentures which, under the terms of such
indentures, cannot be modified or amended without the consent of the holders of
all of the outstanding debt securities of the series affected.

     The indentures contain provisions entitling the trustee, subject to the
duty of the trustee during an event of default to act with the required standard
of care, to be indemnified by the holders of the debt securities of the relevant
series before proceeding to exercise any right or power under the indentures at
the request of those holders.

     The indentures require the trustee to, within 90 days after the occurrence
of a default known to it with respect to any series of outstanding debt
securities, give the holders of that series notice of the default if uncured and
unwaived. However, the trustee may withhold this notice if it in good faith
determines that the withholding of this notice is in the interest of those
holders. However, the trustee may not withhold this notice in the case of a
default in payment of principal, premium, interest or sinking fund installment
with respect to any debt securities of the series. The above notice shall not be
given until at least 60 days after the occurrence of a default in the
performance or a breach of a covenant or warranty in the applicable indenture
other than a covenant to make payment. The term "default" for the purpose of
this provision means any event that is, or after notice or lapse of time, or
both, would become, an event of default with respect to the debt securities of
that series.

     Each indenture requires us to file annually with the trustee a certificate,
executed by one of our officers, indicating whether the officer has knowledge of
any default under the indenture.

REPLACEMENT OF SECURITIES

     We will replace any mutilated debt security at the expense of the holder
upon surrender of the mutilated debt security to the appropriate trustee. We
will replace debt securities that are destroyed, stolen or lost at the expense
of the holder upon delivery to the appropriate trustee of evidence of the
destruction, loss or theft of the debt securities satisfactory to us and to the
trustee. In the case of a destroyed, lost or stolen debt security, an indemnity
satisfactory to the appropriate trustee and us may be required at the expense of
the holder of the debt security before a replacement debt security will be
issued.

DEFEASANCE

     When we use the term defeasance, we mean discharge from some or all of our
obligations under the indenture. If we deposit with the trustee funds or
government securities sufficient to make payments on any series of debt
securities on the dates those payments are due and payable and other specified
conditions are satisfied, then, at our option, either of the following will
occur:

     - we will be discharged from our obligations with respect to the debentures
       ("legal defeasance"); or

     - the related events of default will no longer apply to us ("covenant
       defeasance").

     If we defease any series of debt securities, the holders of such securities
will not be entitled to the benefits of the applicable indenture, except for our
obligations to register the transfer or exchange of such securities, replace
stolen, lost or mutilated securities or maintain paying agencies and hold moneys
for payment in trust. In case of covenant defeasance, our obligation to pay
principal, premium and interest on the applicable series of debt securities will
also survive.

                                        12


     We will be required to deliver to the trustee an opinion of counsel that
the deposit and related defeasance would not cause the holders of the applicable
series of debt securities to recognize income, gain or loss for federal income
tax purposes. If we elect legal defeasance, that opinion of counsel must be
based upon a ruling from the United States Internal Revenue Service or a change
in law to that effect.

GOVERNING LAW

     The indentures and the debt securities will be governed by, and construed
in accordance with, the laws of the State of New York.

SENIOR DEBT SECURITIES LIMITATIONS ON LIENS

     Neither we nor any domestic subsidiary of ours will issue, assume or
guarantee any debt secured by a mortgage, lien, pledge or other encumbrance upon
real or personal property of ours or of any of our domestic subsidiaries that is
located in the continental U.S. without providing that the senior securities
will be secured equally and ratably or prior to the debt. However, this
provision shall not apply to the following:

     - Mortgages existing on the date of the senior indenture;

     - Mortgages existing at the time a corporation becomes a domestic
       subsidiary of ours or at the time it is merged into or consolidated with
       us or a domestic subsidiary of ours;

     - Mortgages in favor of Anadarko or any domestic subsidiary of ours;

     - Mortgages on property (a) existing at the time of the property's
       acquisition, (b) to secure payment of all or part of the property's
       purchase price, or (c) to secure debt incurred prior to, at the time of
       or within 180 days after the acquisition, the completion of construction
       or the commencement of full operation of the property or for the purpose
       of financing all or part of the property's purchase price;

     - Mortgages in favor of the United States of America, any state, any other
       country or any political subdivision required by contract or statute;

     - Mortgages on property to secure all or part of the cost of construction,
       development or repair, alteration or improvement of the property not
       later than one year after the completion of or the placing into operation
       the property;

     - Mortgages on minerals or geothermal resources in place, or on related
       leasehold or other property interests which are incurred to finance
       development, production or acquisition costs;

     - Mortgages on equipment used or usable for drilling, servicing or
       operation of oil, gas, coal or other mineral properties or of geothermal
       properties;

     - Mortgages required by any contract or statute in order to permit us or a
       subsidiary of ours to perform any contract or subcontract made with or at
       the request of the U S., any state or any department, agency or
       instrumentality of either; or

     - Any extension, renewal or replacement of any mortgage referred to in the
       preceding items or of any debt secured by those mortgages as long as the
       extension, renewal or replacement will be limited to substantially the
       same property (plus improvements) which secured the mortgage.

     Notwithstanding anything mentioned above, we and any one or more of our
domestic subsidiaries may issue, assume or guarantee debt secured by mortgages
that would otherwise be subject to the foregoing restrictions in an aggregate
principal amount which, together with the aggregate outstanding principal amount
of all other debt of ours and our domestic subsidiaries that

                                        13


would otherwise be subject to the foregoing restrictions, does not at any one
time exceed 10% of the aggregate amount of assets of Anadarko and its domestic
subsidiaries after deducting therefrom all current liabilities, unamortized debt
discount, expense and other like intangibles as calculated on our consolidated
balance sheet as of a date within 150 days prior to the date of determination.

     The following types of transactions, among others, shall not be deemed to
create debt secured by mortgages: (1) the sale or other transfer of oil, gas or
other minerals in place for a period of time until, or in an amount such that,
the transferee will realize from the sale or transfer a specified amount
(however determined) of money or such minerals, or the sale or other transfer of
any other interest in property of the character commonly referred to as an oil
payment or a production payment, and (2) the sale or transfer by Anadarko or a
domestic subsidiary of properties to a partnership, joint venture or other
entity in which we or our domestic subsidiary would retain partial ownership of
the properties.

THE TRUSTEE

     The Bank of New York is trustee under the senior indenture. The trustee or
its affiliates have other customary banking relationships with us and our
affiliates.

SUBORDINATED DEBT SECURITIES

     Under the subordinated indenture, payment of the principal, interest and
any premium on the subordinated securities will generally be subordinated in
right of payment to the prior payment in full of all of our senior indebtedness.

     "Senior indebtedness" is defined as the principal of, any premium and
accrued and unpaid interest on the following items, whether outstanding on or
created, incurred or assumed after the date of execution of the subordinated
indenture:

     - our indebtedness for money borrowed (other than the subordinated
       securities);

     - guarantees by us of indebtedness for money borrowed of any other person;
       and,

     - indebtedness evidenced by notes, debentures, bonds or other instruments
       of indebtedness for the payment of which we are responsible or liable, by
       guarantees or otherwise.

     Senior indebtedness shall also be deemed to include modifications,
renewals, extensions and refundings of any of the types of indebtedness,
liability, obligations or guarantee listed above, unless the relevant instrument
provides that such indebtedness, liability, obligation or guarantee, or such
modification, renewal, extension or refunding, is not senior in right of payment
to the subordinated securities.

     No payment by us on account of principal of, any premium or interest on the
subordinated securities except for sinking fund payments as described below may
be made if:

     - any default or event of default with respect to any senior indebtedness
       occurs and is continuing, or

     - any judicial proceeding is pending with respect to any default in payment
       of senior indebtedness.

     Sinking fund payments may be made during a suspension of principal or
interest payments on subordinated debt provided the sinking fund payments are
made by securities redeemed or acquired prior to the default or by means of
conversion of the securities.

     If any subordinated security is declared due and payable before its
specified date, or upon any payment or distribution of assets by us to creditors
upon our dissolution, winding up, liquidation or reorganization, all principal
of, any premium and interest due or to become due on all senior

                                        14


indebtedness must be paid in full before the holders of subordinated securities
are entitled to receive or take any payment. Subject to the payment in full of
all senior indebtedness, the holders of the subordinated securities are to be
subrogated to the rights of the holders of senior indebtedness to receive
payments or distribution of our assets applicable to senior indebtedness until
the subordinated securities are paid in full.

     By reason of this subordination, in the event of insolvency, our creditors
who are holders of senior indebtedness, as well as some of our general
creditors, may recover more, ratably, than the holders of the subordinated
securities.

     The subordinated indenture will not limit the amount of senior indebtedness
or debt securities which may be issued by us or any of our subsidiaries.

CONVERSION RIGHTS

     The prospectus supplement will provide if a series of our debt securities
is convertible into Anadarko stock and the initial conversion price per share at
which the securities may be converted.

     The subordinated indenture contains additional provisions regarding
conversion rights. If a convertible subordinated security has not been redeemed,
the holder of such convertible security may convert the security, or any portion
of the principal amount in integral multiples of $1,000, at the conversion price
in effect at the time of conversion into shares of Anadarko stock. Conversion
rights shall expire at the close of business on the date specified in the
prospectus supplement for a series of convertible subordinated securities.
Conversion rights expire at the close of business on the redemption date in the
case of any convertible subordinated securities called for redemption.

     In order to exercise the conversion privilege, the person entitled to
convert the convertible subordinated security must surrender to Anadarko, at any
office or agency of Anadarko maintained for that purpose, the security with a
written notice of the election to convert the security, and if less than the
entire principal amount of the security is being converted, the amount of
security to be converted. In addition, if the convertible subordinated security
is converted during the period between a record date for the payment of interest
and the related interest payment date the person entitled to convert the debt
security must pay to Anadarko an amount equal to the interest payable on the
principal amount being converted.

     No interest on converted subordinated securities will be paid by Anadarko
on any interest payment date after the date of conversion except for those
securities surrendered during the period between a record date for the payment
of interest and the related interest payment date.

     Convertible subordinated securities shall be deemed to have been converted
immediately prior to the close of business on the day of surrender of the
security. No fractional shares of stock will be issued upon conversion, but an
adjustment in cash will be made based on the market price at the close of
business on the date of conversion.

     The conversion price will be subject to adjustment upon the occurrence of
events specified in the applicable prospectus supplement. Anadarko may also
decrease the conversion price as it considers necessary in order that any event
treated for Federal income tax purposes as a dividend of stock or stock rights
will not be taxable to the holders of Anadarko stock.

     Anadarko will pay any and all transfer taxes that may be payable in respect
of the issue or delivery of shares of stock on conversion of the securities.
Anadarko is not required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of shares in a name other than that
of the holder of the security to be converted and no issue and delivery shall be
made unless and until the person requesting the issue has paid the amount of any
such tax or established to the satisfaction of Anadarko that such tax has been
paid.

                                        15


     After the occurrence of:

     - consolidation with or merger of Anadarko into any other corporation;

     - any merger of another corporation into Anadarko; or

     - any sale or transfer of substantially all of the assets of Anadarko

which results in any reclassification, change or conversion of the stock, the
holders of any convertible subordinated securities will be entitled to receive
on conversion the kind and amount of shares of stock or other securities, cash
or other property receivable upon such event by a holder of Anadarko stock
immediately prior to the occurrence of the event.

                         DESCRIPTION OF PREFERRED STOCK

     Our Restated Articles of Incorporation authorize the board of directors of
Anadarko, without further stockholder action, to provide for the issuance of up
to 2,000,000 shares of preferred stock, in one or more series, and to fix the
designations, terms, and relative rights and preferences, including the dividend
rate, voting rights, conversion rights, redemption and sinking fund provisions
and liquidation values of each of these series. We may amend from time to time
our restated articles to increase the number of authorized shares of preferred
stock. Any amendment like this would require the approval of the holders of a
majority of the outstanding shares. As of the date of this prospectus, we have
200,000 shares of 5.46% Series B Cumulative Preferred Stock outstanding and
200,000 shares of Series C Junior Participating Preferred Stock authorized for
issuance under our rights agreement, none of which is outstanding.

     The particular terms of any series of preferred stock being offered by us
under this shelf registration will be described in the prospectus supplement
relating to that series of preferred stock. Those terms may include:

     - the title and liquidation preference per share of the preferred stock and
       the number of shares offered;

     - the purchase price of the preferred stock;

     - the dividend rate (or method of calculation), the dates on which
       dividends will be paid and the date from which dividends will begin to
       accumulate;

     - any redemption or sinking fund provisions of the preferred stock;

     - any conversion provisions of the preferred stock;

     - the voting rights, if any, of the preferred stock; and,

     - any additional dividend, liquidation, redemption, sinking fund and other
       rights, preferences, privileges, limitations and restrictions of the
       preferred stock.

     If the terms of any series of preferred stock being offered differ from the
terms set forth in this prospectus, those terms will also be disclosed in the
prospectus supplement relating to that series of preferred stock. You should
also refer to the certificate of designation establishing a particular series of
preferred stock that will be filed with the Secretary of State of the State of
Delaware and the SEC in connection with any offering of preferred stock.

     The preferred stock will, when issued, be fully paid and nonassessable.

DIVIDEND RIGHTS

     The preferred stock will be preferred over the common stock as to payment
of dividends. Before any dividends or distributions (other than dividends or
distributions payable in common

                                        16


stock) on the common stock shall be declared and set apart for payment or paid,
the holders of shares of each series of preferred stock will be entitled to
receive dividends when, as and if declared by the board of directors of
Anadarko. We will pay those dividends either in cash, shares of common stock or
preferred stock or otherwise, at the rate and on the date or dates set forth in
the prospectus supplement. With respect to each series of preferred stock, the
dividends on each share of the series will be cumulative from the date of issue
of the share unless some other date is set forth in the prospectus supplement
relating to the series. Accruals of dividends will not bear interest.

RIGHTS UPON LIQUIDATION

     The preferred stock will be preferred over the common stock as to asset
distributions so that the holders of each series of preferred stock will be
entitled to be paid, upon our voluntary or involuntary liquidation, dissolution
or winding up and before any distribution is made to the holders of common
stock, the amount set forth in the applicable prospectus supplement. However, in
this case the holders of preferred stock will not be entitled to any other or
further payment. If upon any liquidation, dissolution or winding up our net
assets are insufficient to permit the payment in full of the respective amounts
to which the holders of all outstanding preferred stock are entitled, our entire
remaining net assets will be distributed among the holders of each series of
preferred stock in amounts proportional to the full amounts to which the holders
of each series are entitled.

REDEMPTION

     All shares of any series of preferred stock will be redeemable to the
extent set forth in the prospectus supplement relating to the series. All shares
of any series of preferred stock will be convertible into shares of common stock
or into shares of any other series of preferred stock to the extent set forth in
the applicable prospectus supplement.

PREFERRED STOCK PURCHASE RIGHTS

     On October 30, 1998, we entered into a rights agreement with The Chase
Manhattan Bank, as rights agent, providing for a dividend of one preferred stock
purchase right for each outstanding share of our common stock. We issued the
dividend to stockholders of record on November 10, 1998, and holders of shares
of common stock issued since that date are issued rights with their shares. The
rights trade automatically with shares of common stock and become exercisable
only under the circumstances described below. The rights are designed to protect
the interests of Anadarko and our stockholders against coercive takeover
tactics. The purpose of the rights is to encourage potential acquirers to
negotiate with the board of directors of Anadarko prior to attempting a takeover
and to provide the board with leverage in negotiating on behalf of all
stockholders the terms of any proposed takeover. The rights may have
anti-takeover effects. The rights should not, however, interfere with any merger
or other business combination approved by the board of directors of Anadarko.

     Until a right is exercised, the right will not entitle the holder to
additional rights as an Anadarko stockholder, including, without limitation, the
right to vote or to receive dividends. Upon becoming exercisable, each right
will entitle its holder to purchase from us one one-thousandth of a share of
Series C Junior Participating Preferred Stock at a purchase price of $175 per
right, subject to adjustment. In general, the rights will not be exercisable
until the earlier of (a) any time that we learn that a person or group or an
affiliate or associate of the person or group has acquired, or has obtained the
right to acquire, beneficial ownership of 15% or more of our outstanding common
stock, unless provisions preventing accidental triggering of the rights apply
and (b) the close of business on the date, if any, designated by the board of
directors of Anadarko following the commencement of, or first public disclosure
of an intent to commence, a tender or exchange offer for 15% or more of our
outstanding common stock. Below we refer to the earlier of those dates as

                                        17


the "distribution date" and the person or group acquiring at least 15% of our
common stock as an "acquiring person." In the event that we are acquired in a
merger or other business combination, or 50% or more of our consolidated assets
or earning power are sold after a person becomes an acquiring person, each right
will entitle its holder to purchase, for the purchase price, that number of
common shares of the corporation which at the time of the transaction would have
a market value of twice the right exercise price.

     Any rights that are at any time beneficially owned by an acquiring person,
or any associate or affiliate of the acquiring person, will be null and void and
nontransferable, and any holder of such right, including any purported
transferee or subsequent holder, will be unable to exercise or transfer the
right.

     The rights will expire at the close of business on November 10, 2008,
unless redeemed before that time. At any time prior to the earlier of (a) the
time a person or group becomes an acquiring person and (b) the expiration date,
the board of directors of Anadarko may redeem the rights in whole, but not in
part, at a price of $.01 per right. This amount is subject to adjustment as
provided in the rights agreement.

     The preceding summary is not complete and is not intended to give full
effect to provisions of statutory or common law. You should refer to the
applicable provisions of the rights agreement and the form of right certificate,
which are incorporated by reference to Exhibit 4.1 to our Form 8-A, filed with
the SEC on October 30, 1998.

PROVISIONS OF ANADARKO'S RESTATED CERTIFICATE OF INCORPORATION

     In the event of a proposed merger or tender offer, proxy contest or other
attempt to gain control of us which is not approved by the board of directors of
Anadarko, it would be possible for the board of directors of Anadarko to
authorize the issuance of one or more series of preferred stock with voting
rights or other rights and preferences which would impede the success of the
proposed merger, tender offer, proxy contest or other attempt to gain control of
us. This authority may be limited by applicable law, the restated articles and
the applicable rules of the stock exchanges upon which the common stock is
listed. The consent of the holders of common stock would not be required for any
issuance of preferred stock like this.

     The restated articles also provide that the board of directors of Anadarko
is classified into three classes and that some provisions of the restated
articles may be amended only by the affirmative vote of the holders of at least
80% of the voting power of our then outstanding voting stock.

                        DESCRIPTION OF DEPOSITARY SHARES

     We may, at our option, elect to offer fractional shares of preferred stock,
rather than full shares of preferred stock. If we exercise this option, we will
issue to the public receipts for depositary shares, and each of these depositary
shares will represent a fraction (to be set forth in the applicable prospectus
supplement) of a share of a particular series of preferred stock.

     The shares of any series of preferred stock underlying the depositary
shares will be deposited under a deposit agreement between us and a bank or
trust company selected by us. The depositary will have its principal office in
the United States and a combined capital and surplus of at least $50,000,000.
Subject to the terms of the deposit agreement, each owner of a depositary share
will be entitled, in proportion to the applicable fraction of a share of
preferred stock underlying that depositary share, to all the rights and
preferences of the preferred stock underlying that depositary share. Those
rights include dividend, voting, redemption and liquidation rights.

     The depositary shares will be evidenced by depositary receipts issued
pursuant to the deposit agreement. Depositary receipts will be distributed to
those persons purchasing the fractional shares of preferred stock underlying the
depositary shares, in accordance with the terms of the offering.

                                        18


Copies of the forms of deposit agreement and depositary receipt will be filed as
exhibits to the registration statement. The following summary of the deposit
agreement, the depositary shares and the depositary receipts is not complete.
You should refer to the forms of the deposit agreement and depositary receipts
that will be filed with the SEC in connection with the offering of the specific
depositary shares.

     Pending the preparation of definitive engraved depositary receipts, the
depositary may, upon our written order, issue temporary depositary receipts
substantially identical to the definitive depositary receipts but not in
definitive form. These temporary depositary receipts entitle their holders to
all the rights of definitive depositary receipts which are to be prepared
without unreasonable delay. Temporary depositary receipts will then be
exchangeable for definitive depositary receipts at our expense.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The depositary will distribute all cash dividends or other cash
distributions received with respect to the preferred stock to the record holders
of depositary shares relating to the preferred stock in proportion to the number
of depositary shares owned by those holders.

     If there is a distribution other than in cash, the depositary will
distribute property received by it to the record holders of depositary shares
that are entitled to receive the distribution, unless the depositary determines
that it is not feasible to make the distribution. If this occurs, the depositary
may, with our approval, sell the property and distribute the net proceeds from
the sale to the applicable holders.

REDEMPTION OF DEPOSITARY SHARES

     If a series of preferred stock represented by depositary shares is subject
to redemption, the depositary shares will be redeemed from the proceeds received
by the depositary resulting from the redemption, in whole or in part, of that
series of preferred stock held by the depositary. The redemption price per
depositary share will be equal to the applicable fraction of the redemption
price per share payable with respect to that series of the preferred stock.
Whenever we redeem shares of preferred stock that are held by the depositary,
the depositary will redeem, as of the same redemption date, the number of
depositary shares representing the shares of preferred stock so redeemed. If
fewer than all the depositary shares are to be redeemed, the depositary shares
to be redeemed will be selected by lot or pro rata as may be determined by the
depositary.

VOTING THE PREFERRED STOCK

     Upon receipt of notice of any meeting at which the holders of the preferred
stock are entitled to vote, the depositary will mail the information contained
in the notice to the record holders of the depositary shares underlying the
preferred stock. Each record holder of the 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 as to the exercise of the voting rights
pertaining to the amount of the preferred stock represented by such holder's
depositary shares. The depositary will then try, as far as practicable, to vote
the number of shares of preferred stock underlying those depositary shares in
accordance with such instructions, and we will agree to take all actions which
may be deemed necessary by the depositary to enable the depositary to do so. The
depositary will not vote the shares of preferred stock to the extent it does not
receive specific instructions from the holders of depositary shares underlying
the preferred stock.

AMENDMENT AND TERMINATION OF THE DEPOSITARY AGREEMENT

     The form of depositary receipt evidencing the depositary shares and any
provision of the deposit agreement may at any time be amended by agreement
between us and the depositary. However, any amendment which materially and
adversely alters the rights of the holders of

                                        19


depositary shares will not be effective unless the amendment has been approved
by the holders of at least a majority of the depositary shares then outstanding.
The deposit agreement may be terminated by us or by the depositary only if (a)
all outstanding depositary shares have been redeemed or (b) there has been a
final distribution of the underlying preferred stock in connection with our
liquidation, dissolution or winding up and the preferred stock has been
distributed to the holders of depositary receipts.

CHARGES OF DEPOSITARY

     We will pay all transfer and other taxes and governmental charges arising
solely from the existence of the depositary arrangements. We will also pay
charges of the depositary in connection with the initial deposit of the
preferred stock and any redemption of the preferred stock. Holders of depositary
receipts will pay other transfer and other taxes and governmental charges and
those other charges, including a fee for the withdrawal of shares of preferred
stock upon surrender of depositary receipts, as are expressly provided in the
deposit agreement to be for their accounts.

MISCELLANEOUS

     The depositary will forward to holders of depositary receipts all reports
and communications from us that we deliver to the depositary and that we are
required to furnish to the holders of the preferred stock.

     Neither we nor the depositary will be liable if either of us is prevented
or delayed by law or any circumstance beyond our control in performing our
respective obligations under the deposit agreement. Our obligations and those of
the depositary will be limited to performance in good faith of our respective
duties under the deposit agreement. Neither we nor they will be obligated to
prosecute or defend any legal proceeding in respect of any depositary shares or
preferred stock unless satisfactory indemnity is furnished. We and the
depositary may rely upon written advice of counsel or accountants, or upon
information provided by persons presenting preferred stock for deposit, holders
of depositary receipts or other persons believed to be competent and on
documents believed to be genuine.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The depositary may resign at any time by delivering notice to us of its
election to resign. We may remove the depositary at any time. Any resignation or
removal will take effect upon the appointment of a successor depositary and its
acceptance of the appointment. The successor depositary must be appointed within
60 days after delivery of the notice of resignation or removal and must be a
bank or trust company having its principal office in the United States and
having a combined capital and surplus of at least $50,000,000.

                          DESCRIPTION OF COMMON STOCK

     As of the date of this prospectus, we are authorized to issue up to
450,000,000 shares of common stock. As of February 1, 2001, we had 253,417,690
shares of common stock issued and had reserved 20,546,663 additional shares of
common stock for issuance under our various stock and compensation incentive
plans.

     The following summary is not complete and is not intended to give full
effect to provisions of statutory or common law. You should refer to the
applicable provisions of the following documents:

     - the restated certificate of incorporation, which are incorporated by

if declared by the board of directors of Anadarko, out of funds legally
available for their payment subject to the rights of holders of preferred stock.

VOTING RIGHTS

     The holders of common stock are entitled to one vote per share on all
matters submitted to a vote of stockholders.

RIGHTS UPON LIQUIDATION

     In the event of our voluntary or involuntary liquidation, dissolution or
winding up, the holders of common stock will be entitled to share equally in any
of our assets available for distribution after the payment in full of all debts
and distributions and after the holders of all series of outstanding preferred
stock have received their liquidation preferences in full.

MISCELLANEOUS

     The outstanding shares of common stock are fully paid and nonassessable.
The holders of common stock are not entitled to preemptive or redemption rights.
Shares of common stock are not convertible into shares of any other class of
capital stock. ChaseMellon Shareholder Services LLC, New York, New York, is the
transfer agent and registrar for the common stock.

                       DESCRIPTION OF SECURITIES WARRANTS

     We may issue securities warrants for the purchase of debt securities,
preferred stock or common stock. Securities warrants may be issued independently
or together with debt securities, preferred stock or common stock and may be
attached to or separate from any offered securities. Each series of securities
warrants will be issued under a separate warrant agreement to be entered into
between us and a bank or trust company, as warrant agent. The securities warrant
agent will act solely as our agent in connection with the securities warrants
and will not assume any obligation or relationship of agency or trust for or
with any registered holders of securities warrants or beneficial owners of
securities warrants. In addition to this summary, you should refer to the
securities warrant agreement, including the forms of securities warrant
certificate representing the securities warrants, relating to the specific
securities warrants being offered for the complete terms of the securities
warrant agreement and the securities warrants. That securities warrant
agreement, together with the terms of securities warrant certificate and
securities warrants, will be filed with the SEC in connection with the offering
of the specific securities warrants.

     The particular terms of any issue of securities warrants will be described
in the prospectus supplement relating to the issue. Those terms may include:

     - the designation, aggregate principal amount, currencies, denominations
       and terms of the series of debt securities purchasable upon exercise of
       securities warrants to purchase debt securities and the price at which
       the debt securities may be purchased upon exercise;

     - the designation, number of shares, stated value and terms (including,
       without limitation, liquidation, dividend, conversion and voting rights)
       of the series of preferred stock purchasable upon exercise of securities
       warrants to purchase shares of preferred stock and the price at which
       such number of shares of preferred stock of such series may be purchased
       upon such exercise;

                                        21


     - the number of shares of common stock purchasable upon the exercise of
       securities warrants to purchase shares of common stock and the price at
       which such number of shares of common stock may be purchased upon such
       exercise;

     - the date on which the right to exercise the securities warrants will
       commence and the date on which the right will expire;

     - United States Federal income tax consequences applicable to the
       securities warrants; and,

     - any other terms of the securities warrant.

     Securities warrants for the purchase of preferred stock and common stock
will be offered and exercisable for U.S. dollars only. Securities warrants will
be issued in registered form only. The exercise price for securities warrants
will be subject to adjustment in accordance with the applicable prospectus
supplement.

     Each securities warrant will entitle its holder to purchase the principal
amount of debt securities or the number of shares of preferred stock or common
stock at the exercise price set forth in, or calculable as set forth in, the
applicable prospectus supplement. The exercise price may be adjusted upon the
occurrence of events as set forth in the prospectus supplement. After the close
of business on the expiration date, unexercised securities warrants will become
void. We will specify the place or places where, and the manner in which,
securities warrants may be exercised in the applicable prospectus supplement.

     Prior to the exercise of any securities warrants to purchase debt
securities, preferred stock or common stock, holders of the securities warrants
will not have any of the rights of holders of the debt securities, preferred
stock or common stock purchasable upon exercise, including:

     - in the case of securities warrants for the purchase of debt securities,
       the right to receive payments of principal of, any premium or interest on
       the debt securities purchasable upon exercise or to enforce covenants in
       the applicable indenture; or,

     - in the case of securities warrants for the purchase of preferred stock or
       common stock, the right to vote or to receive any payments of dividends
       on the preferred stock or common stock purchasable upon exercise.

              DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

     We may issue purchase contracts representing contracts obligating holders
to purchase from Anadarko, and Anadarko to sell to the holders, or for Anadarko
to issue in exchange for other securities a specified number of shares of common
stock or preferred stock (or a range of numbers of shares pursuant to a
predetermined formula) at a future date or dates or on the occurrence of
specified events. The price or exchange rate per share of common stock or
preferred 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 purchase contracts may be issued separately or as a part of units,
often known as purchase units, consisting of a purchase contract and the
following:

     - senior debt securities or subordinated securities of Anadarko or one of
       its subsidiaries;

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

     - trust preferred securities of the Trusts, all of whose trust common
       securities are owned by Anadarko or by subsidiaries of Anadarko; or

     - any combination of the foregoing

                                        22


securing the holder's obligations to purchase the common stock or preferred
stock under the purchase contracts.

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

     The applicable prospectus supplement will describe the terms of any
purchase contracts or purchase units and, if applicable, prepaid securities. The
description in the applicable prospectus supplement will not purport to be
complete, and may not contain all of the information that you may find useful.
For more information, you should review the purchase contracts, the collateral
arrangements and the depositary arrangements, if applicable, relating to such
purchase contracts or purchase units and, if applicable, the prepaid securities
and the document pursuant to which the prepaid securities will be issued. These
documents will be filed with the SEC promptly after the offering of such
purchase contracts or purchase units and, if applicable, prepaid securities.

                   DESCRIPTION OF TRUST PREFERRED SECURITIES

     Each Trust may issue only one series of trust preferred securities. The
Trust Agreement of each Trust will authorize the administrative trustees to
issue the trust preferred securities of that Trust on behalf of that Trust. For
additional information you should refer to the applicable trust agreement. The
form of trust agreement is an exhibit to the registration statement, of which
this prospectus is a part.

     The prospectus supplement for a particular series of trust preferred
securities being offered will disclose the specific terms related to the
offering, including the price or prices at which the trust preferred securities
to be offered will be issued. Those terms will include some or all of the
following:

     - the title of the series;

     - the number of trust preferred securities of the series;

     - the yearly distribution rate, or the method of determining that rate, and
       the date or dates on which distributions will be payable;

     - the date or dates, or method of determining the date or dates, from which
       distributions will be cumulative;

     - the amount that will be paid out of the assets of the Trust to the
       holders of the trust preferred securities upon the voluntary or
       involuntary dissolution, winding-up or termination of the Trust;

     - any obligation that the Trust has to purchase or redeem the trust
       preferred securities, and the price at which, the period within which,
       and the terms and conditions upon which the Trust will purchase or redeem
       them;

     - any voting rights of the trust preferred securities that are in addition
       to those legally required, including any right that the holders of the
       trust preferred securities have to approve certain actions under or
       amendments to the trust agreement;

                                        23


     - any right that the Trust has to defer distributions on the trust
       preferred securities in the event that Anadarko extends the interest
       payment period on the related subordinated debt securities of Anadarko;
       and

     - any other rights, preferences, privileges, limitations or restrictions
       upon the trust preferred securities of the series.

     Anadarko will guarantee each series of trust preferred securities to the
extent described below under the caption "Description of Guarantees."

     The applicable prospectus supplement will describe any material United
States federal income tax considerations that apply to the trust preferred
securities.

                           DESCRIPTION OF GUARANTEES

     Anadarko will execute the guarantees from time to time for the benefit of
the holders of the trust preferred securities of the respective Trusts. The Bank
of New York will act as guarantee trustee under each guarantee. The guarantee
trustee will hold each guarantee for the benefit of the holders of the trust
preferred securities to which it relates.

     The following description of the guarantees is only a summary and is not
intended to be comprehensive. The form of guarantee is an exhibit to the
registration statement, of which this prospectus is a part.

GENERAL

     Anadarko will irrevocably and unconditionally agree under each guarantee to
pay the guarantee payments that are described below, to the extent specified in
that guarantee, to the holders of the trust preferred securities to which the
guarantee relates, to the extent that the guarantee payments are not paid by or
on behalf of the related Trust. Anadarko is required to pay the guarantee
payments to the extent specified in the relevant guarantee regardless of any
defense, right of set-off or counterclaim that Anadarko may have or may assert
against any person.

     The following payments and distributions on the trust preferred securities
of a Trust are guarantee payments:

     - any accrued and unpaid distributions required to be paid on the trust
       preferred securities of the Trust, but only to the extent that the Trust
       has funds legally and immediately available for those distributions;

     - the redemption price for any trust preferred securities that the Trust
       calls for redemption, including all accrued and unpaid distributions to
       the redemption date, but only to the extent that the Trust has funds
       legally and immediately available for the payment; and

     - upon dissolution, winding-up or termination of the Trust, other than in
       connection with the distribution of subordinated notes to the holders of
       trust securities of the Trust or the redemption of all the trust
       preferred securities of the Trust, the lesser of:

      - the sum of the liquidation amount and all accrued and unpaid
        distributions on the trust preferred securities of the Trust to the
        payment date, to the extent that the Trust has funds legally and
        immediately available for the payment; and

      - the amount of assets of the Trust remaining available for distribution
        to holders of the trust preferred securities of the Trust in liquidation
        of the Trust.

     Anadarko may satisfy its obligation to make a guarantee payment by making
that payment directly to the holders of the related trust preferred securities
or by causing the Trust to make the payment to those holders.

                                        24


     Each guarantee will be a full and unconditional guarantee, subject to
certain subordination provisions, of the guarantee payments with respect to the
related trust preferred securities from the time of issuance of those trust
preferred securities, except that the guarantee will only apply to the payment
of distributions and other payments on the trust preferred securities when the
Trust has sufficient funds legally and immediately available to make those
distributions or other payments.

     If Anadarko does not make the required payments on the subordinated notes
that the property trustee holds under a Trust, that Trust will not make the
related payments on its trust preferred securities.

SUBORDINATION

     Anadarko's obligations under each guarantee will be unsecured obligations
of Anadarko. Those obligations will rank:

     - subordinate and junior in right of payment of all of Anadarko's other
       liabilities, other than obligations or liabilities that rank equal in
       priority or subordinate by their terms;

     - equal in priority with Anadarko's preferred stock and 5.46% Series B
       Cumulative Preferred Stock and similar guarantees; and

     - senior to Anadarko's common stock.

     Anadarko has 5.46% Series B Cumulative Preferred Stock outstanding that
will rank equal in priority with the guarantees and has common stock outstanding
that will rank junior to the guarantees.

     Each guarantee will be a guarantee of payment and not of collection. This
means that the guaranteed party may institute a legal proceeding directly
against Anadarko, as guarantor, to enforce its rights under the guarantee
without first instituting a legal proceeding against any other person or entity.

     The terms of the trust preferred securities will provide that each holder
of the trust preferred securities, by accepting those trust preferred
securities, agrees to the subordination provisions and other terms of the
related guarantee.

AMENDMENTS AND ASSIGNMENT

     Anadarko may amend each guarantee without the consent of any holder of the
trust preferred securities to which that guarantee relates if the amendment does
not materially and adversely affect the rights of those holders. Anadarko may
otherwise amend each guarantee with the approval of the holders of at least
66 2/3% of the outstanding trust preferred securities to which that guarantee
relates.

TERMINATION

     Each guarantee will terminate and be of no further effect when:

     - the redemption price of the trust preferred securities to which the
       guarantee relates is fully paid;

     - Anadarko distributes the related subordinated debt securities to the
       holders of those trust preferred securities; or

     - the amounts payable upon liquidation of the related Trust are fully paid.

     Each guarantee will remain in effect or will be reinstated if at any time
any holder of the related trust preferred securities must restore payment of any
sums paid to that holder with respect to those trust preferred securities or
under that guarantee.

                                        25


EVENTS OF DEFAULT

     An event of default will occur under any guarantee if Anadarko fails to
perform any of its payment obligations under that guarantee. The holders of a
majority of the trust preferred securities of any series may waive any such
event of default and its consequences on behalf of all of the holders of the
trust preferred securities of that series. The guarantee trustee is obligated to
enforce the guarantee for the benefit of the holders of the trust preferred
securities of a series if an event of default occurs under the related
guarantee.

     The holders of a majority of the trust preferred securities to which a
guarantee relates have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the guarantee trustee with
respect to that guarantee or to direct the exercise of any trust or power that
the guarantee trustee holds under that guarantee. Any holder of the related
trust preferred securities may institute a legal proceeding directly against
Anadarko to enforce that holder's rights under the guarantee without first
instituting a legal proceeding against the guarantee trustee or any other person
or entity.

CONCERNING THE GUARANTEE TRUSTEE

     The Bank of New York will be the guarantee trustee. It will also be the
property trustee, the subordinated indenture trustee and the senior indenture
trustee. Anadarko and certain of its affiliates maintain deposit accounts and
banking relationships with The Bank of New York. The Bank of New York also
serves as trustee under other indentures pursuant to which securities of
Anadarko and certain of its affiliates are outstanding.

     The guarantee trustee will perform only those duties that are specifically
set forth in each guarantee unless an event of default under the guarantee
occurs and is continuing. In case an event of default occurs and is continuing,
the guarantee trustee will exercise the same degree of care as a prudent
individual would exercise in the conduct of his or her own affairs. Subject to
those provisions, the guarantee trustee is under no obligation to exercise any
of its powers under any guarantee at the request of any holder of the related
trust preferred securities unless that holder offers reasonable indemnity to the
guarantee trustee against the costs, expenses and liabilities which it might
incur as a result.

AGREEMENTS AS TO EXPENSES AND LIABILITIES

     Anadarko will enter into an agreement as to expenses and liabilities under
each Trust Agreement. Each agreement as to expenses and liabilities will provide
that Anadarko will, with certain exceptions, irrevocably and unconditionally
guarantee the full payment of any indebtedness, expenses or liabilities of the
related Trust to each person or entity to whom that Trust becomes indebted or
liable. The exceptions are the obligations of the Trust to pay to the holders of
the related trust preferred securities or other similar interests in that Trust
the amounts due to the holders under the terms of those trust preferred
securities or those similar interests.

               RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES,
                     THE DEBT SECURITIES AND THE GUARANTEES

     As long as we make payments of interest and other payments when due on the
subordinated debt securities purchased by a Trust, those payments will be
sufficient to cover distributions and other payments due on the trust preferred
securities, primarily because:

     - the aggregate principal amount of the subordinated debt securities will
       be equal to the sum of the aggregate stated liquidation preference of the
       trust securities;

                                        26


     - the interest rate and interest and other payment dates of the
       subordinated debt securities will match the distribution rate and
       distribution and other payment dates for the trust preferred securities;

     - we will pay any and all costs, expenses and liabilities of the Trusts,
       except the Trusts' obligations to holders of its trust preferred
       securities under the terms of such trust preferred securities; and

     - the trust agreement of each Trust prohibits the trust from engaging in
       any activity that is not consistent with the limited purposes of the
       Trust.

     We irrevocably guarantee payments of distributions and other amounts due on
the trust preferred securities of a Trust, to the extent the Trust has funds
available for the payment of such distributions as described in "Description of
Guarantees" in this prospectus. Taken together, our obligations under the
subordinated debt securities, the subordinated indenture, the trust agreements
and the trust guarantees provide a full, irrevocable and unconditional guarantee
of payments of distributions and other amounts due on the trust preferred
securities. No single document standing alone or operating in conjunction with
fewer than all of the other documents constitutes such 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 of the Trust's obligations
under its trust preferred securities. If we do not make payments on the
subordinated debt securities, the Trusts will not pay distributions or other
amounts due on the trust preferred securities. The trust guarantees do not cover
payment of distributions when the applicable Trust does not have sufficient
funds to pay the distributions. In this event, the remedies of a holder of the
trust preferred securities of the trust are described in this prospectus under
"Description of Guarantees -- Events of Default." Our obligations under the
trust guarantees are unsecured and are subordinate and junior in right of
payment to all of our other liabilities.

     Notwithstanding anything to the contrary in the subordinated indenture and
to the extent set forth in the subordinated indenture, we have the right to
set-off any payment we are otherwise required to make under the indenture with
and to the extent we have made or are concurrently on the date of such payment
making, a payment under a trust guarantee.

     A holder of trust preferred securities of a Trust may institute a legal
proceeding directly against us to enforce its rights under the trust guarantee
without first instituting a legal proceeding against the trust guarantee
trustee, the Trust or any other person or entity.

     The trust preferred securities of a Trust evidence a beneficial interest in
the trust. The Trusts exist for the sole purpose of issuing the trust securities
and investing the proceeds in our subordinated debt securities. A principal
difference between the rights of a holder of trust preferred securities and a
holder of subordinated debt securities is that a holder of subordinated debt
securities is entitled to receive from us the principal amount of and interest
accrued on debt securities held, while a holder of trust preferred securities is
entitled to receive distributions from a trust, or from us under the trust
guarantee, if and to the extent the trust has funds available for the payment of
such distributions.

     Upon any voluntary or involuntary termination, winding-up or liquidation of
a trust involving the liquidation of the subordinated debt securities, the
holders of the trust preferred securities of the trust will be entitled to
receive, out of assets held by the trust and after satisfaction of liabilities
to creditors of the trust as provided by applicable law, the liquidation
distribution in cash. Upon any voluntary or involuntary liquidation or
bankruptcy of us, the property trustees of a trust, as holder of the
subordinated debt securities of the trust, would be a subordinated creditor of
us, subordinated in right of payment to all of our senior debt, but entitled to
receive payment in full of principal and interest, before any of our
stockholders receive payments or distributions. Since we are the guarantor under
the trust guarantees and we have agreed to pay for all costs, expenses and
liabilities of the Trusts other than the Trusts' obligations to the holders of
the trust preferred

                                        27


securities, the positions of a holder of trust preferred securities and a holder
of subordinated debt securities relative to other creditors and to our
shareholders in the event of our liquidation or bankruptcy would be
substantially the same.

     A default or event of default under any of our senior debt will not
constitute a default or event of default under the subordinated indenture.
However, in the event of payment defaults under, or acceleration of, our senior
debt, the subordination provisions of the subordinated indenture provide that no
payments may be made on the debt securities until our senior debt has been paid
in full or any payment default under our senior debt has been cured or waived.
Our failure to make required payments on a series of subordinated debt
securities would constitute an event of default under the subordinated
indenture.

                              PLAN OF DISTRIBUTION

     We may sell the debt securities, preferred stock, depositary shares, common
stock, securities warrants, purchase contracts, purchase units or trust
preferred securities (together referred to as the "offered securities") (a)
through underwriters or dealers, (b) directly to one or a limited number of
institutional purchasers or (c) through agents. This prospectus or the
applicable prospectus supplement will set forth the terms of the offering of any
offered securities, including the name or names of any underwriters, dealers or
agents, the price of the offered securities and the net proceeds to us from such
sale, any underwriting commissions or other items constituting underwriters'
compensation.

     If underwriters are used in the sale, the offered securities will be
acquired by the underwriters for their own account and may be resold from time
to time 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 offered securities may be offered to the public either through underwriting
syndicates represented by managing underwriters or directly by one or more
investment banking firms or others, as designated. Unless otherwise set forth in
the applicable prospectus supplement, the obligations of the underwriters or
agents to purchase the offered securities will be subject to conditions
precedent and the underwriters will be obligated to purchase all the offered
securities if any are purchased. Any initial public offering price and any
underwriting commissions or other items constituting underwriters' compensation
may be changed from time to time.

     If a dealer is utilized in the sale of any offered securities, we will sell
those offered securities to the dealer, as principal. The dealer may then resell
the offered securities to the public at varying prices to be determined by the
dealer at the time of resale.

     We may sell offered securities directly to one or more institutional
purchasers, or through agents at a fixed price or prices, which may be changed,
or at varying prices determined at time of sale. Unless otherwise indicated in
the prospectus supplement, any agent will be acting on a best effort basis for
the period of its appointment.

     If an applicable prospectus supplement indicates, we will authorize agents,
underwriters or dealers to solicit offers by specified institutions to purchase
offered securities from us at the public offering price set forth in the
prospectus supplement under delayed delivery contracts providing for payment and
delivery on a specified date in the future. These contracts will be subject only
to those conditions set forth in the prospectus supplement, and the prospectus
supplement will set forth the commission payable for solicitation of the
contracts.

     Under agreements entered into with us, agents and underwriters who
participate in the distribution of the offered securities may be entitled to
indemnification by us against certain civil liabilities, including liabilities
under the Securities Act of 1933, or to contribution with respect to payments
which the agents or underwriters may be required to make. Agents and
underwriters may be customers of, engage in transactions with or perform
services for us in the ordinary course of business.

     The validity of the offered securities will be passed upon for us by
Andrews & Kurth L.L.P. Houston, Texas, and for any underwriters, dealers or
agents by Hughes Hubbard & Reed LLP, New York, New York.
