ITEM 1. BUSINESS
 
     In Item 1 of this Form 10-K, including the production and reserve
disclosures contained therein, the Company has included a number of forward
looking statements within the meaning of Section 27A of the Securities Act of
1933 and Section 21E of the Securities Exchange Act of 1934. These forward
looking statements are based on the best data available at the time this report
was released for printing; however, actual results could differ materially from
those expressed or implied by such statements. See Additional Factors Affecting
Business in the Management's Discussion and Analysis under Item 7 of this Form
10-K.
 
GENERAL
 
     Anadarko Petroleum Corporation is one of the world's largest independent
oil and gas exploration and production companies with 601 million energy
equivalent barrels (MMEEBs) of proved reserves.
     The Company's reserve mix has shifted dramatically in recent years,
primarily due to major crude oil discoveries both in Algeria and the U.S., which
have resulted in a larger and more balanced portfolio of energy reserves. As of
year-end 1996, crude oil, condensate and natural gas liquids (NGLs) reserves
accounted for 50 percent of the Company's total reserves compared to just six
percent at year-end 1986.
     About 80 percent of the Company's proved reserves are located in the U.S.,
primarily in the mid-continent (Kansas, Oklahoma and Texas) area, offshore in
the Gulf of Mexico and in Alaska. Currently, all of the Company's production is
in the U.S. The Company also owns interests in 13 gas gathering systems and four
gas processing plants in the U.S.
     Internationally, Anadarko is exploring for and developing crude oil
reserves in Algeria's Sahara Desert. To date, the Company has recorded 124.3
million barrels (MMBbls) of proved crude oil and condensate reserves in Algeria,
which accounts for about 20 percent of Anadarko's total proved reserves.
Development operations are now underway. The Company is also participating in
other exploration projects in Eritrea, Jordan and Peru.
     The principal subsidiaries of Anadarko include: Anadarko Gathering Company;
Anadarko Energy Services Company (formerly Anadarko Trading Company); and,
Anadarko Algeria Corporation (Anadarko Algeria). Unless the context otherwise
requires, the terms "Anadarko" or "Company" refer to Anadarko and its
subsidiaries. The Company's corporate offices are located at 17001 Northchase
Drive, Houston, Texas 77060-2141, where the telephone number is (281) 875-1101.
 
PROVED RESERVES AND FUTURE NET CASH FLOWS
 
     Proved oil and gas reserves are the estimated quantities of natural gas,
crude oil, condensate and NGLs which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions. Reserves are
considered proved if economical producibility is supported by either actual
production or conclusive formation tests. Reserves which can be produced
economically through application of improved recovery techniques are included in
the "proved" classification when successful testing by a pilot project or the
operation of an installed program in the reservoir provides support for the
engineering analysis on which the project or program was based.
     Proved developed oil and gas reserves can be expected to be recovered
through existing wells, with existing equipment and operating methods.
     As of December 31, 1996, Anadarko had proved reserves of 1.82 trillion
cubic feet (Tcf) of natural gas and 297.8 MMBbls of crude oil, condensate and
NGLs. Combined, these proved reserves are equivalent to 601.3 MMEEBs of oil or
3.61 Tcf of gas. The Company's reserves have grown significantly over the past
three years. Reserve growth is due mainly to the dramatic increase in crude oil
reserves discovered in Algeria, the Gulf of Mexico and Alaska. Crude oil,
condensate and NGLs comprised 50 percent of Anadarko's total reserves at
year-end 1996. The volumes of the Company's natural gas reserves have remained
relatively stable over the last three years.
 
                                        2
<PAGE>   4
 
     Proved developed reserves comprise 63 percent of the total proved reserves
on an energy equivalent barrel (EEB) basis. As of December 31, 1996, Anadarko
had proved developed reserves of 1.65 Tcf of natural gas and 100.6 MMBbls of
crude oil, condensate and NGLs.
     The Company's estimates of proved reserves and proved developed reserves
owned at December 31, 1996, 1995 and 1994 and changes in proved reserves during
the last three years are contained in the Supplemental Information on Oil and
Gas Exploration and Production Activities (Supplemental Information) in the
Anadarko Petroleum Corporation 1996 Consolidated Financial Statements
(Consolidated Financial Statements) under Item 8 of this Form 10-K Annual Report
(Form 10-K). The Company files annual estimates of certain proved oil and gas
reserves with the Department of Energy, which are within five percent of these
amounts.
     Also contained in the Supplemental Information in the Consolidated
Financial Statements are the Company's estimates of future net cash flows,
discounted future net cash flows before income taxes and discounted future net
cash flows after income taxes from proved reserves.
     The Company emphasizes that the volumes of reserves are estimates which, by
their nature, are subject to revision. The estimates are made using all
available geological and reservoir data, as well as production performance data.
These estimates are reviewed annually and revised, either upward or downward, as
warranted by additional performance data.

PROPERTIES AND ACTIVITIES -- INTERNATIONAL
 
OVERVIEW  In recent years, Anadarko has devoted a portion of its exploration
budget to selected international exploration projects. The Company's objective
is to add high-potential prospects to its balanced portfolio of domestic plays.
Management believes this strategy will help ensure long-term growth for the
Company. Exploration and development work is underway in Algeria and exploration

ALGERIA  Anadarko's largest international venture involves exploration for and
development of liquid hydrocarbons in Algeria's Sahara Desert. Since 1989,
Anadarko has drilled 14 successful wells (seven exploration and seven
delineation) and discovered five major fields in Algeria. The Company has booked
proved reserves of 124.3 MMBbls (net) of crude oil and condensate as of year-end
1996.
     As of December 31, 1996, the Company's total net investment in Algeria was
$232 million of which about $85 million was spent in 1996. Due to the success of
the project thus far, these expenditures are currently being capitalized and no
provision for loss or impairment has been made. Anadarko plans to invest $191
million in Algeria in 1997. To date, the Company has elected not to insure its
investment in Algeria. At the end of 1996, the Company had 5.3 million gross
(2.3 million net) acres in Algeria.
     The accompanying map illustrates the Company's undeveloped acreage, number
of productive wells and other data relevant to its properties in Algeria.

     Anadarko's interest in the production sharing agreement (PSA) relating to
the four Company-operated blocks is 50 percent before participation at the
exploitation stage by SONATRACH, the national oil and gas enterprise of Algeria.
The Company has two partners, each with a 25-percent interest in the Algerian
venture, also prior to participation by SONATRACH; they are LASMO Oil (Algeria)
Limited, a wholly-owned subsidiary of LASMO plc, and Maersk Olie Algeriet AS, a
wholly-owned subsidiary of Maersk Olie Og Gas AS, a company in the Danish A.P.
Moeller group. Under the terms of the PSA, liquid hydrocarbons that are
discovered, developed and produced will be shared by SONATRACH, Anadarko and its
two partners. SONATRACH is responsible for 51 percent of development and
production costs. In addition, Anadarko and its partners are entitled to recover
a portion of exploration costs out of production in the exploitation phase.
SONATRACH is also the beneficial owner of 10.1 percent of Anadarko's outstanding
common stock.
     During 1996, SONATRACH received a Provisional Exploitation Authorization
(PEA) for wells in the Hassi Berkine (HBN) and the Hassi Berkine South (HBNS)
Fields located on Block 404. Anadarko and its partners signed a $177 million
Engineering, Procurement and Construction (EPC) contract in 1996 with Brown &
Root Condor for Stage I production facilities at the HBNS Field. Four wells have
been drilled in the HBNS Field to date and partners expect to drill additional
development wells in the Field in 1997. Initial gross production is estimated at
about 60,000 barrels of oil per day (BOPD) and is expected to begin in early
1998. Anadarko's 1997 work program in Algeria will focus on development of known
discoveries with continued exploration.
     In 1997, Anadarko plans a two-rig drilling program to drill up to 10
exploration wells. Four exploration wells were drilled in 1996 and three were
discoveries.
     The Company also has a 27.5-percent interest in a PSA covering two
additional blocks -- Blocks 401 and 402 -- in the same region, which are
operated by BHP Petroleum (Algerie) Inc. An exploration program is underway on
these two blocks. In 1996, BHP and Anadarko shot 1,900 kilometers of
high-quality seismic and plans call for drilling two exploratory wells during
1997.
     Political unrest exists in Algeria. Anadarko is closely monitoring the
situation and has taken reasonable and prudent steps to ensure the safety of
employees working in the remote regions of the Sahara Desert. Anadarko is
presently unable to predict with certainty any effect the current situation may
have on activity planned for 1997 and beyond. However, the situation has not had
any material effect to date on the Company's operations.
 
ERITREA  In September 1995, Anadarko signed an agreement with the government of
the State of Eritrea for offshore exploration on a 6.7 million-acre area in the
Red Sea and plans to invest about $30 million over the next several years.
Anadarko invested about $8 million on its Eritrea work program in 1996 and plans
to spend about $8 million in 1997.
     In 1996, Anadarko completed a high-density aerial gravity and magnetic
survey over the exploration area, known as the Zula Block, and acquired 4,500
kilometers of data across the block. During 1997, the data will be analyzed and
combined with existing data from other operators. The Company plans to drill its
first exploratory well in Eritrea in late 1997 or early 1998. The Company has a
100-percent interest in the project, but may take partners.
 
JORDAN  In March 1996, Anadarko and the Natural Resources Authority of the
Hashemite Kingdom of Jordan signed a PSA covering 4.2 million acres, known as
the Safawi Block. The Company invested about $2 million on its Jordan efforts in
1996 and has budgeted about $4 million for 1997.
     In 1996, Anadarko conducted a magnetotelluric survey of the area and
reprocessed more than 1,000 kilometers of existing seismic data. The information
will be used to determine locations for two stratigraphic test wells planned for
1997. These wells will analyze source rock and look for signs of a working
petroleum system. Anadarko operates the venture with a 50-percent interest. In
February 1997, a subsidiary of Union Texas Petroleum joined Anadarko as a
partner in Jordan with a 50-percent interest.
 
PERU  In September 1996, Anadarko signed an exploration license agreement with
PERUPETRO S.A., the state oil company in Peru. Anadarko has the right to explore
a 2.56-million acre area, known as Block 84. Anadarko invested about $2 million
in Peru in 1996 and has budgeted about $2 million for 1997.
 
                                        6
<PAGE>   8
 
     In late 1996, Anadarko flew a 7,300 kilometer aerial magnetic survey of the
area to help determine specific locations for a 700 kilometer seismic shoot
scheduled for 1997. The Company also plans an additional aerial magnetic survey
in 1997. Anadarko owns a 100-percent interest in the venture, but may take
partners.
 
INDONESIA  In September 1996, Anadarko sold its wholly-owned subsidiary,
Anadarko Indonesia Company, Jabung, for $36.8 million. Anadarko's net income in
1996 benefited from a gain on the sale of $19.4 million ($12.3 million after
income taxes). The sale was a part of the Company's ongoing strategy to divest
"non-core" assets and reinvest proceeds in core operating areas. Anadarko and
its partners had discovered two fields in Indonesia with estimated proved
reserves of 17.7 MMEEBs.
 
CHINA  The Company has decided not to pursue exploration efforts in China's
Sichuan Province at this time and is in discussions to farm-out the Company's
interests. As a result, Anadarko recognized an impairment of $4.6 million in the
third quarter of 1996. The Company has a 100-percent interest in the project.
 
PROPERTIES AND ACTIVITIES -- UNITED STATES
 
OFFSHORE
 
OVERVIEW  At year-end 1996, the Company's reserves offshore in the Gulf of
Mexico were approximately 13 percent of total proved reserves. In 1996,
production from these properties was about 119 million cubic feet per day
(MMcf/d) of gas and 2,000 BOPD, or 21 percent of the Company's total production
volumes. At year-end 1996, Anadarko owned an average 49 percent working interest
in 116 lease blocks representing 178,000 gross (56,000 net) acres in developed
properties and 435,000 gross (232,000 net) acres in undeveloped properties
offshore.
     The accompanying map illustrates the Company's undeveloped and developed
net acreage, number of net producing wells and other data relevant to its
offshore properties.
 
EXPLORATION  Anadarko is active in exploration projects in both the conventional
and sub-salt plays offshore in the Gulf of Mexico.
     In 1996, Anadarko concentrated its offshore exploration efforts in the
sub-salt play. The Company drilled five sub-salt exploratory wells, announcing
two discoveries -- Agate, located at Ship Shoal 361, and Monazite, located at
Vermilion South Addition 375. Anadarko and Phillips Petroleum Company (operator)
each own a 50-percent working interest in the Agate well. Anadarko (operator),
Broken Hill Proprietary (BHP) and Phillips each hold a 33.33-percent working
interest in the Monazite well. The first sub-salt discovery -- Mahogany -- came
on-line in late 1996 (See Development). Anadarko and partners are considering
the possibility of tying Agate production to the Mahogany platform. The Company
will continue to evaluate its portfolio of 17 prospects in the play and has five
ready-to-drill sub-salt prospects in 1997.
     The Company also drilled three conventional exploration wells offshore in
the Gulf of Mexico in 1996 -- all dry holes. Two additional exploration wells
began drilling in late 1996. Three conventional exploration wells are planned in
1997.
     Until 1996, the Company's principal acreage position offshore was in the
shallow water (less than 400 feet). However, in 1996, Anadarko made its entrance
into the deepwater play (more than 1,000 feet). In Offshore Lease Sale No. 161
in September 1996, Anadarko and partners acquired 12 lease blocks in the Gulf of
Mexico's deepwater play with water depths ranging from 2,700-5,700 feet.
Anadarko operates 10 of the 12 blocks and plans to acquire 3-D seismic data on
seven of the blocks in 1997. One exploratory well may be drilled in the
deepwater play in late 1997. In April 1996, Anadarko acquired seven shallow
lease blocks in Offshore Lease Sale No. 157. The leases are located in the
central Gulf of Mexico.

DEVELOPMENT  During 1996, the production platform for Mahogany, the industry's
first commercial sub-salt development, was installed on Ship Shoal 349, located
about 80 miles offshore Louisiana. Production from the 20-slot platform began in
December 1996 and should increase as additional development wells are drilled
and completed. Phillips (operator) and Anadarko each own a 37.5-percent working
interest in the project. Amoco Production Company holds a 25-percent working
interest.
     Conventional operations focused on development drilling and recompletions.
The Company participated in the completion of three new wells and 10 additional
wells were recompleted. Eight development wells are planned for 1997 offshore in
the Gulf of Mexico.
     Anadarko and partner, Amerada Hess (operator) installed a production
platform at South Marsh Island 192, located about 110 miles offshore Louisiana
in July 1996. Production began in November 1996. The partners may drill
additional wells in the field to increase production volumes.
     In 1996, Anadarko purchased additional interests in the Brazos A-47
production platform, located about 35 miles offshore Texas. The Company
originally owned a 33-percent working interest and obtained the remaining
interests in the field in 1996 by assuming responsibility for disposition of the
existing wells and platform. At the time of the purchase, the platform's three
wells were shut-in. Anadarko plans to drill one development well in the field in
1997. If successful, the Company plans to recomplete one of the existing wells
in late 1997.
 
ONSHORE
 
OVERVIEW  The Company's onshore reserves are approximately 67 percent of total
proved reserves. These reserves are located principally in Kansas, Oklahoma,
Texas and Alaska. In 1996, average production from the Company's onshore
properties was 332 MMcf/d of gas and 16.3 thousand barrels per day (MBOD), or 77
percent of the Company's total production volumes. Anadarko has 1,289,000 gross
(545,000 net) undeveloped lease acres and 1,082,000 gross (795,000 net)
developed acres onshore in the United States.
     The accompanying map illustrates by state Anadarko's undeveloped and
developed net acreage, number of net producing wells and other data relevant to
its onshore oil and gas operations.
 
HUGOTON EMBAYMENT  Anadarko's single largest asset is its reserves in the
Hugoton Embayment, located in southwest Kansas and the Oklahoma Panhandle.
Currently, Anadarko owns 566,000 gross (507,000 net) lease acres in the area and
operates about 2,000 wells. Anadarko's net production from the Hugoton Embayment
in 1996 was 85.8 Bcf of gas and 1.6 MMBbls of oil, or about 42 percent of the
Company's total production volumes. In 1996, Anadarko drilled 72 development
wells and recompleted 27 wells in the area.
     Anadarko's activities in the area are concentrated on two areas: the
shallow Hugoton gas fields and the deeper oil and gas zones below the shallow
Hugoton production. In 1996, Anadarko drilled 17 wells in the Hugoton gas area
and 55 wells in the deeper zones. In 1997, Anadarko plans to drill 30 wells in
the shallow Hugoton area and 100 wells in the deeper zones. Management believes
the increased drilling activity in this area should lead to an increase in the
Company's 1997 production volumes. In addition to development drilling,
Anadarko's operations in this area have benefited from acquisitions of producing
properties, gas gathering systems and waterflood operations.
 
PERMIAN BASIN  Drilling activity reached record levels for Anadarko in late 1996
in the Permian Basin of west Texas and eastern New Mexico. In 1996, net oil
production from the area was 9,500 BOPD, or about half of the Company's total
oil production. In the Permian Basin, Anadarko holds leasehold interests in
237,000 gross (136,000 net) acres and operates about 2,300 active wells. During
1996, Anadarko drilled 182 wells in the area and 10 Company-operated rigs were
running at year-end. The Company plans to drill more than 200 wells in 1997.
Management believes the increased drilling activity should increase the
Company's production volumes from the area in 1997.
 
ALASKA  In October 1996, Anadarko and partners announced commerciality of the
Alpine Field, located on the North Slope about 50 miles west of Prudhoe Bay.
Development work is underway with first production of 30,000 BOPD (gross)
expected in 2000 with peak production of 60,000 BOPD (gross) expected in 2001.
Anadarko owns a 22-percent working interest in this ARCO Alaska-operated field.
In 1996, the partners acquired 5,900 acres near the Alpine Field in State Lease
Sale 86A. In addition to the Alpine Field, Anadarko
 
                                        9
<PAGE>   11
 
and ARCO Alaska acquired six offshore lease blocks in the Beaufort Sea, west of
the Alpine Field. A seismic acquisition program is planned for the area in 1997.
     Anadarko and ARCO Alaska announced formation of a strategic alliance in
1996 to explore the Cook Inlet of southern Alaska. With Anadarko as operator,
the team will review ARCO's existing 127,000 lease acres for exploratory
prospects. In December 1996, the partners acquired an additional 10 lease blocks
(39,000 acres) on the west side of the Cook Inlet and on the Kenai Peninsula. A
seismic acquisition program is underway onshore and the partners hope to have a
list of exploratory prospects ready to drill in 1998.
 
GOLDEN TREND  Activity levels also increased in central Oklahoma's Golden Trend
area. In 1996, the Company drilled 15 successful wells in the area, of which 14
were development wells. Based on the successful results of a 1996 infill
program, Anadarko has picked up a second drilling rig and plans to add a third
rig to accelerate the Company's 31 well program in 1997.
 
GULF COAST  Anadarko is active in the onshore Gulf Coast regions of Mississippi,
Texas and Louisiana. In 1996, Anadarko participated in a large 3-D seismic
acquisition program in the Smackover Play in Wayne County, Mississippi. The data
were analyzed in late 1996 and Anadarko is planning to drill up to four
exploratory wells in the Smackover Play in 1997.
     In 1996, Anadarko drilled one successful exploratory well in the Yegua Play
and, in 1997, the Company is planning to drill at least one delineation well to
offset a 1996 discovery in the Nome Field near Beaumont, Texas.
     In the Wilcox Play, located in south Texas, Anadarko is evaluating
exploratory prospects in Jim Hogg County. During 1996, Anadarko conducted a 3-D
seismic survey on a portion of the Company's acreage. The Company plans to drill
an exploratory well in the Wilcox Play in mid-1997. Anadarko has a 33.33-percent
working interest in the exploratory venture.
 
COAL-BED METHANE  Anadarko is exploring coal-bed methane acreage in the Helper
Field, located in Carbon County, Utah. Anadarko is planning to drill three
exploratory wells on state and private acreage in early 1997.

GATHERING AND PROCESSING
 
GAS GATHERING SYSTEMS  Anadarko owns and operates four major gas gathering
systems in the nation's mid-continent area: the Antioch Gathering System in the
Southwest Antioch Field of Oklahoma; the Hemphill Gathering System, located in
Hemphill County, Texas; the Sneed System in the West Panhandle Field of Texas;
and the Hugoton Gathering System in southwest Kansas (which includes the Hugoton
Gathering Facility (HUGS), the Cimarron River System (CRS) and a portion of the
Panhandle Eastern Pipe Line West End gathering assets acquired in 1996). The
Company's gathering systems have approximately 2,100 miles of pipeline
connecting nearly 2,000 wells and have nearly 500 MMcf/d of gas gathering
capacity. In addition, Anadarko owns interests in nine other smaller gas
gathering systems.
 
GAS PROCESSING PLANTS  Anadarko owns and operates one gas processing plant, the
Sneed Gas Processing Plant located in the West Panhandle Field of Texas, and has
interests in three other plants. These plants are located within the Company's
major areas of gas production. In 1996, the Company closed its Panther Creek Gas
Processing Plant located in the Southwest Antioch Field of Oklahoma because the
Company arranged to have the gas processed more efficiently in third-party

DRILLING PROGRAMS
 
     The Company's 1996 drilling program again focused on known oil and gas
provinces onshore in North America, as well as offshore in the Gulf of Mexico.
Onshore activity was concentrated in Kansas, Oklahoma, the Texas Panhandle, the
Permian Basin of west Texas and Alaska. Exploration activity consisted of 11
wells onshore in the United States, six wells offshore United States, six wells
in Algeria and three wells in Indonesia. Development activity included 254 wells
onshore United States and three wells offshore United States.

EMPLOYEES
 
     On December 31, 1996, the Company employed 1,229 persons. The Company's
employees are not represented by any union. Relations between the Company and
its employees are considered to be satisfactory and the Company has had no work
stoppages or strikes.
 
REGULATORY AND LEGISLATIVE DEVELOPMENTS
 
     See Regulatory Matters under Item 7 of this Form 10-K.
 
ADDITIONAL FACTORS AFFECTING BUSINESS
 
     See Additional Factors Affecting Business under Item 7 of this Form 10-K.
 
TITLE TO PROPERTIES
 
     As is customary in the oil and gas industry, only a preliminary title
examination is conducted at the time properties believed to be suitable for
drilling operations are acquired by the Company. Prior to the commencement of
drilling operations, a thorough title examination of the drill site tract is
conducted and curative work is performed with respect to significant defects, if
any, before proceeding with operations. A thorough title examination has been
performed with respect to substantially all leasehold producing properties owned
by the Company. Anadarko believes the title to its leasehold properties is good
and defensible in accordance with standards generally acceptable in the oil and
gas industry subject to such exceptions which, in the opinion of counsel
employed in the various areas in which the Company has conducted exploration
activities, are not so material as to detract substantially from the use of such
properties. The leasehold properties owned by the Company are subject to
royalty, overriding royalty and other outstanding interests customary in the
industry. The properties may be subject to burdens such as liens incident to
operating agreements and current taxes, development obligations under oil and
gas leases and other encumbrances, easements and restrictions. Anadarko does not
believe any of these burdens will materially interfere with its use of these
properties.
 
CAPITAL SPENDING
 
     See Capital Expenditures and Liquidity and Long-term Debt under Item 7 of
this Form 10-K.
 
RATIOS OF EARNINGS TO FIXED CHARGES AND EARNINGS TO COMBINED FIXED CHARGES AND
PREFERRED STOCK DIVIDENDS
 
     The Company's ratios of earnings to fixed charges for the years ended
December 31, 1996, 1995 and 1994 were 3.34, 1.24 and 2.11, respectively. These
ratios were computed by dividing earnings by fixed charges. 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.
     During the three years ended December 31, 1996, there were no shares of
preferred stock outstanding. Accordingly, the ratio of earnings to combined
fixed charges and preferred stock dividends for each of the three years is the
same as the ratio of earnings to fixed charges.

ITEM 3. LEGAL PROCEEDINGS
 
KANSAS AD VALOREM TAX  The Natural Gas Policy Act of 1978 (NGPA) allows a
"severance, production or similar" tax to be included as an add-on, over and
above the maximum lawful price for natural gas. Based on the Federal Energy
Regulatory Commission (FERC) ruling that the Kansas ad valorem tax was such a
tax, the Company collected the Kansas ad valorem tax in addition to the
otherwise maximum lawful price. FERC's ruling was appealed to the United States
Court of Appeals for the District of Columbia (D.C. Circuit), which held in June
1988 that FERC failed to provide a reasoned basis for its findings and remanded
the case to FERC for further consideration.
     On December 1, 1993, FERC issued an order reversing its prior ruling, but
limiting the effect of its decision to Kansas ad valorem taxes for sales made on
or after June 28, 1988. FERC clarified the effective date of its decision by an
order dated May 19, 1994. The clarification provided that the June 28, 1988
effective date applies to tax bills rendered after that date, not sales made on
or after that date. Based on Anadarko's interpretation of FERC's orders,
$700,000 (pre-tax) was charged against income in 1994, in addition to $130,000
(pre-tax) charged against income in 1993. Numerous parties filed appeals of
FERC's action in the D.C. Circuit. Anadarko, together with other natural gas
producers, challenged FERC's orders on two grounds: (1) that the Kansas ad
valorem tax, properly understood, does qualify for reimbursement under the NGPA;
and (2) FERC's ruling should, in any event, have been applied prospectively.
Other parties separately challenged FERC's orders on the grounds that FERC's
ruling should have been applied retroactively to December 1, 1978, the date of
the enactment of the NGPA and producers should have been required to pay refunds
accordingly.
     The D.C. Circuit issued its decision on August 2, 1996 which holds that
producers must make refunds of all Kansas ad valorem taxes collected with
respect to production since October 1983. Petitions for rehearing were denied on
November 6, 1996. The Company, along with other producing companies,
subsequently filed a petition for writ of certiorari with the United States
Supreme Court seeking to limit the scope of the potential refunds to tax bills
rendered on or after June 28, 1988 (the effective date originally selected by
FERC). The petition has not been acted on. Williams Natural Gas Company has
filed a cross-petition for certiorari seeking to impose refund liability back to
December 1, 1978. The Company and other interested parties will oppose this
cross-petition. If Supreme Court review of the decision is unsuccessful, the
pursuit of other judicial and regulatory relief from the application of this
decision to the Company will be considered. The Company is unable at this time
to predict the final outcome of this matter. If, however, the August 2, 1996,
decision is not reversed or modified by judicial review and if Anadarko is
unable to limit application of the decision to the Company, Anadarko estimates
the maximum amount of principal and interest at issue (assuming that the October
1983 effective date remains in effect) is about $37 million (pre-tax) as of
December 31, 1996.
 
OTHER  The Company is subject to other legal proceedings, claims and liabilities
which arise in the ordinary course of its business. In the opinion of the
Company, the liability with respect to these actions will not have a material
effect on the Company.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
     In Item 7 of this Form 10-K, including the production and reserve
disclosures contained therein, the Company has included a number of forward
looking statements within the meaning of Section 27A of the Securities Act of
1933 and Section 21E of the Securities Exchange Act of 1934. These forward
looking statements are based on the best data available at the time this report
was released for printing; however, actual results could differ materially from
those expressed or implied by such statements due to a number of factors
including those discussed below: commodity pricing and demand, exploration and
operating risks, development risks, domestic governmental risks, foreign
operations risks and competition.
 
FINANCIAL RESULTS
 
NET INCOME AND REVENUES  Anadarko's net income for 1996 increased 379 percent to
$100.7 million ($1.70 per share) compared to 1995 net income of $21.0 million
(36 cents per share). Revenues for 1996 were $569.0 million, up 31 percent
compared to 1995 revenues of $434.0 million. The increase in revenues and net
income reflects significantly higher prices for natural gas, crude oil and
natural gas liquids (NGLs). Net income in 1996 included a gain of $19.4 million
($12.3 million after income taxes) on the sale of the Company's Indonesia
interests, which was partially offset by provisions for impairments of other
international properties of $5.4 million ($3.4 million after income taxes).
     Anadarko's 1994 net income was $41.1 million (70 cents per share). The 1994
results included a non-cash charge of $6.6 million (after income taxes) related
to the sale of the Company's Canadian subsidiary. Stated without giving effect
to the sale, 1994 net income was $47.7 million (81 cents per share). Revenues
for 1994 were $482.5 million. The decreases in revenues and net income in 1995
compared to 1994 reflect lower prices for natural gas in 1995 and lower
production volumes of crude oil in 1995 primarily due to property sales in 1994.

</TABLE>
 
COSTS AND EXPENSES  Over the past three years, Anadarko's expense levels have
remained relatively constant due to attention and focus on cost controls, cost
savings plans and application of new technology to field production operations.
In 1996, excluding the effect of the sale of the Company's Indonesia interests,
Anadarko's costs and expenses increased six percent compared to 1995. Costs and
expenses in 1996 were primarily impacted by the following factors:
     (1) Operating expenses increased $9.5 million (nine percent) due primarily
         to costs associated with gas gathering operations.
     (2) Administrative and general expenses were up $8.2 million (14 percent)
         due to higher costs associated with the Company's growing workforce.
     (3) The Company recorded provisions for impairments of international
         properties of $5.4 million in 1996. (These impairments were offset by
         the gain on a sale of the Company's Indonesia assets of $19.4 million.)
         The 1996 impairments reflect costs associated with the review and study
         of potential exploration projects in China and several other foreign
         countries that the Company has elected not to pursue. This compares to
         $2.6 million of provisions for impairments of international and
         geothermal properties in 1995.

<PAGE>   21
     The Company's 1995 costs and expenses decreased five percent compared to
1994, excluding the sale of the Company's Canadian subsidiary in 1994. There
were several reasons:
     (1) Operating expenses decreased $4.4 million (four percent) due primarily
         to lower oil and gas operating expenses.
     (2) Depreciation, depletion and amortization (DD&A) expense decreased $8.1
         million (five percent) due to a two percent decrease in gas production
         volumes and a 10 percent decrease in crude oil production partly due to
         property sales in late 1994. In addition, the DD&A rate decreased four
         percent due to additional reserves booked during the year.
     (3) Administrative and general expenses were down $1.7 million (three
         percent) due to increases in overhead capitalized and amounts charged
         to other working interest partners.
     (4) Other taxes decreased $4.1 million (10 percent) due primarily to lower
         natural gas prices and lower production volumes, which resulted in
         lower production and severance taxes.
     (5) Provisions for impairments of international and geothermal properties
         decreased $0.5 million (16 percent). These impairments in 1995
         primarily reflect costs associated with geothermal exploration projects
         and the review and study of potential exploration projects in several
         foreign countries, which the Company elected not to pursue.

</TABLE>
 
INTEREST EXPENSE  Anadarko's gross interest expense has increased 27 percent
over the past three years due primarily to higher levels of borrowings for
capital expenditures, including producing property acquisitions. Gross interest
expense in 1996 was up six percent compared to 1995 primarily due to higher
average borrowings in 1996. Gross interest expense in 1995 increased 19 percent
compared to 1994 primarily due to higher average borrowings and interest rates
in 1995. Net interest expense benefited in 1994 from an option sold for an
interest rate swap agreement that was not exercised by the purchaser, which
reduced interest expense in 1994 by $2.6 million. See Liquidity and Long-term
Debt.

ANALYSIS OF VOLUMES AND PRICES
 
NATURAL GAS Anadarko's natural gas production volumes in 1996 decreased four
percent compared to 1995 production primarily due to sales of producing
properties in 1995 and natural decline. Gas production volumes in 1994 were at
record levels. The Company's average U.S. wellhead gas price in 1996 was up 50
percent from 1995. Anadarko's average U.S. wellhead gas price in 1995 had
declined 17 percent from 1994. Management
 
                                       20
<PAGE>   22
 
expects the Company's natural gas production volumes in 1997 will increase due
to increased levels of drilling activity in the Company's core operating areas.
     During 1996, Anadarko marketed more third-party gas volumes than Company
gas production volumes. The Company marketed 200 Bcf of third-party gas in 1996
compared to 109 Bcf in 1995 and 84 Bcf in 1994. The significant increase in
third-party sales is a key marketing strategy for the Company.
     The gas price weakness that began in late 1994 continued until mid-December
1995, when a surge in heating demand caused by extreme winter conditions sent
gas prices significantly higher. Natural gas markets were extremely volatile in
1996, with the Company's average price fluctuating from a low of $1.66 per Mcf
in September 1996 to a high of $3.49 per Mcf in December 1996. The increase in
1996 prices can be attributed to several factors: temperatures in the winter of
1995-96 were colder than normal in the northeast and midwest heating markets;
the nation's storage volumes were lower at the beginning of the 1996 heating
season compared to 1995 due to heavy storage withdrawals and higher prices for
natural gas in the typical injection season (May-October) that prohibited
storage volumes from reaching traditional levels; and the 1996 heating season
opened with colder than normal temperatures.
     This experience shows no one can predict the precise movement of U.S.
natural gas prices. In view of this, Anadarko has developed marketing strategies
to help manage production and sales volumes and mitigate the effect of the price
volatility that is likely to continue. See Marketing Strategies -- Use of
Derivatives.

CRUDE OIL, CONDENSATE AND NATURAL GAS LIQUIDS  Anadarko's crude oil and
condensate production in 1996 was down 10 percent from 1995. The 1995 oil and
condensate production volumes declined 10 percent compared to 1994. The
decreases in oil production over the last three years are due primarily to
property sales in 1994 and 1995 and normal production declines associated with
mature oil fields.
     Anadarko's average U.S. crude oil price for 1996 increased 22 percent
compared to 1995. Crude oil prices in 1995 were up 10 percent compared to 1994.
Crude oil prices have continued to be strong in the first quarter of 1997 in
response to seasonal demand for heating oils. Prices for January 1997 averaged
about $23.00 per barrel.

     Generally, the Company's oil production is sold on a monthly basis as it is
produced. Production of oil usually is not affected by seasonal swings in demand
or in market prices.
     The Company's NGLs sales volumes in 1996 decreased two percent compared to
1995 volumes. The 1995 NGLs sales volumes were two percent higher than 1994 NGLs
sales. The 1996 average price was up 32 percent compared to 1995. The 1995 NGLs
average price was nine percent higher than the 1994 average price.

MARKETING STRATEGIES
 
NATURAL GAS  The U.S. natural gas market has grown significantly throughout the
last 10 years and management believes continued growth to be likely. Management
believes the Company's excellent portfolio of exploration and development
prospects should position Anadarko to continue to participate in this growth.
     Anadarko's wholly-owned marketing subsidiary -- Anadarko Energy Services
Company (AES) (formerly Anadarko Trading Company) -- is a full-service marketing
company offering supply assurance, competitive pricing and tailored services to
its customers. Most of the Company's gas production is sold through AES.
Additionally, AES purchases and sells third party gas. In 1996, sales of
third-party gas exceeded sales of the Company's gas production volumes.
     AES sells natural gas under a variety of contracts and may also receive a
service fee related to the level of reliability and service required by the
customer. AES has expanded its marketing capabilities to move larger volumes of
gas into and out of the "daily" gas market to take advantage of any price
volatility. Included in this strategy is expanded use of leased natural gas
storage facilities and various hedging strategies to better manage price risk
associated with natural gas sales. See Use of Derivatives.
 
CRUDE OIL AND CONDENSATE  Currently, all of Anadarko's revenues are derived from
domestic production. Presently, the Company's crude oil production is sold on
30-day "evergreen" contracts with prices based on postings plus a premium.
Initial production from the HBNS field in Algeria, estimated at about 60,000
barrels of oil per day (BOPD) (gross) is expected in early 1998. Anadarko's
marketing department is currently exploring international markets for the
Saharan Blend crude oil.
 
GAS GATHERING SYSTEMS AND PROCESSING PLANTS  Anadarko's investment in gas
gathering operations allows the Company to better manage its gas production,
improve ultimate recovery of reserves, enhance the value of reserves and expand
marketing opportunities. The Company has invested more than $85 million to build
or acquire gas gathering systems over the last five years. Anadarko owned and
operated four major gas gathering systems and one gas processing plant at the
end of 1996. In addition, the Company owned interests in nine other gathering
systems and three other processing plants at year-end 1996.
     In March 1996, Anadarko closed on the second of two recent acquisitions
from PanEnergy Corp, formerly Panhandle Eastern Corporation. The purchase price
of the two systems was about $35 million. These two gathering systems tripled
the Company's overall gas gathering capacity to over 480 MMcf/d and serve
approximately 1,900 wells. Approximately 75 percent of the gas flowing through
these systems is from Anadarko-operated wells. During 1996, Anadarko invested an
additional $15 million to lower line pressure and
 
                                       22
<PAGE>   24
 
increase deliverability from systems in southwest Kansas. Anadarko plans to
invest an additional $45 million on enhancing its gathering systems over the
next several years and improve access to multiple pipeline market hubs.
     Anadarko remains active in the NGLs business, primarily as a result of its
gas gathering and processing operations. The Company generally sells NGLs on a
monthly basis as they are produced. However, some NGLs are held in inventory for
sale at a later date. Anadarko generally markets NGLs under short-term
contracts. Anadarko had 4,600 barrels of NGLs in inventory at the end of 1996
compared to 66,600 barrels at the end of 1995.
 
USE OF DERIVATIVES  Anadarko uses derivative financial instruments to hedge the
Company's exposure to changes in the market price of natural gas and crude oil,
to provide methods to fix the price for natural gas independently of the
physical purchase or sale and to manage interest rates. Commodity financial
instruments also provide methods to meet customer pricing requirements while
achieving a price structure consistent with the Company's overall pricing
strategy. While commodity financial instruments are intended to reduce the
Company's exposure to declines in the market price of natural gas and crude oil,
the commodity financial instruments may also limit Anadarko's gain from
increases in the market price of natural gas and crude oil. As a result, gains
and losses on commodity financial instruments are generally offset by similar
changes in the realized price of natural gas and crude oil. Gains and losses are
recognized in revenues for the periods to which the commodity financial
instruments relate. Anadarko's commodity financial instruments currently are
comprised of futures, swaps and options. See Note 6 of the Notes to Consolidated
Financial Statements under Item 8 of this Form 10-K.
 
OPERATING RESULTS
 
DRILLING ACTIVITY  During 1996, Anadarko participated in a total of 283 gross
wells, including 166 oil wells, 65 gas wells and 52 dry holes. This compares to
258 wells (114 oil wells, 98 gas wells and 46 dry holes) in 1995 and 281 wells
(147 oil wells, 95 gas wells and 39 dry holes) in 1994.
     During 1996, the Company made several significant well completions in its
exploration and development drilling program which are discussed in the
narrative descriptions on pages 9 through 23 of the 1996 Annual Report to
Stockholders, incorporated herein by reference, and Properties and Activities
under Item 1 of this Form 10-K.

RESERVE REPLACEMENT  Drilling activity is not the best measure of success for an
exploration and production company. Anadarko focuses on growth and
profitability. Reserve replacement is the key to growth and future
 
                                       23
<PAGE>   25
 
profitability depends on the cost of finding oil and gas reserves. The Company
believes its performance in both areas is excellent. For the 15th consecutive
year, Anadarko more than replaced annual production volumes with proved reserves
of natural gas, crude oil, condensate and NGLs, stated on an energy equivalent
barrel (EEB) basis.
     During 1996, Anadarko's worldwide reserve replacement was 299 percent of
total production, which was 37.7 million energy equivalent barrels (MMEEBs). The
Company's worldwide reserve replacement in 1995 was 226 percent of total
production and in 1994 was 308 percent of total production. Over the last five
years, the Company's annual reserve replacement has averaged 241 percent of
annual production volumes.
     In 1996, the Company replaced 215 percent of its production volumes with
U.S. reserves. The Company's U.S. reserve replacement for the five-year period
1992-96 was 183 percent of Anadarko's U.S. production. By comparison, the most
recent published U.S. industry average (1991-95) was 84 percent. (Source:
Department of Energy.) Anadarko's U.S. reserve replacement performance for the
same period 1991-95 was 175 percent of production. Industry data for 1996 are
not yet available.
 
COST OF FINDING  For 1996, Anadarko's worldwide finding cost for proved reserves
was $2.76 per EEB compared to $2.74 per EEB in 1995 and to $2.76 per EEB in
1994. The Company's low worldwide finding costs are due to the success of the
Company's exploration programs. Anadarko's U.S. finding cost for 1996 was $3.23
per EEB compared to $4.26 per EEB in 1995 and $3.57 per EEB in 1994.
     Cost of finding results in any one year can be misleading due to the long
lead times associated with exploration and development. A better measure of cost
of finding performance is over a five-year period. Anadarko has consistently
outperformed the industry in average finding costs. For the period 1992-96,
Anadarko's U.S. cost of finding was $3.78 per EEB. Anadarko's worldwide finding
cost for the same five-year period was $3.25 per EEB. Industry data for 1996 are
not yet available. For comparison purposes, the most recent published five-year
average (1991-95) for the industry shows U.S. average cost of finding was $4.77
per EEB and worldwide cost of finding was $5.19 per EEB. (Source: Arthur
Andersen, SC) For the same period, Anadarko's U.S. finding cost was $3.74 per
EEB and worldwide finding cost was $3.39 per EEB.
 
PROVED RESERVES  At the end of 1996, Anadarko's proved reserves were 601.3
MMEEBs compared to 526.3 MMEEBs at year-end 1995 and 476.4 MMEEBs at year-end
1994. Reserves increased by 14 percent in 1996 compared to 1995, primarily due
to exploration and development drilling and improved recovery. Anadarko's proved
reserves have grown by 54 percent over the past three years, primarily as a
result of successful exploration projects in Algeria, the Gulf of Mexico and
Alaska, as well as successful exploitation and development drilling programs in
major domestic fields in core areas onshore and offshore.
     The Company's proved natural gas reserves at year-end 1996 were 1.82
trillion cubic feet (Tcf) compared to 1.84 Tcf at year-end 1995 and 1.91 Tcf at
year-end 1994. Anadarko's crude oil, condensate and NGLs reserves at year-end
1996 increased 36 percent to 297.8 MMBbls compared to 219.2 MMBbls at year-end
1995. This compares to reserves of 157.4 MMBbls at year-end 1994. Crude oil
reserves have increased 279 percent over the last three years due to large
discoveries in Algeria, the Gulf of Mexico and Alaska. Crude oil, condensate and
NGLs reserves now comprise 50 percent of the Company's proved reserves compared
to about 42 percent at year-end 1995 and about 33 percent at year-end 1994.
Creating balance between crude oil reserves and natural gas reserves was a key
strategy for the Company.
     The Company emphasizes that the volumes of reserves are estimates which, by
their nature, are subject to revision. The estimates are made using all
available geologic and reservoir data as well as production performance data.
These estimates are reviewed annually and revised, either upward or downward, as
warranted by additional performance data.
     At December 31, 1996, the present value (discounted at 10 percent) of
future net revenues from Anadarko's proved reserves was $5.27 billion, before
income taxes, and was $3.40 billion, after income taxes, (stated in accordance
with the regulations of the Securities and Exchange Commission and Financial
Accounting Standards Board). The 1996 estimated present value of future net
revenues, after income taxes, increased 96 percent compared to 1995 primarily
due to increases in commodity prices for oil and gas at year-end 1996 and the
additions of proved reserves related to successful drilling worldwide. See
Supplemental Information on Oil and Gas Exploration and Production Activities in
the Consolidated Financial Statements under Item 8 of this Form 10-K.
 
                                       24
<PAGE>   26
 
     The present value of future net revenues does not purport to be an estimate
of the fair market value of Anadarko's proved reserves. An estimate of fair
value would also take into account, among other things, anticipated changes in
future prices and costs, the expected recovery of reserves in excess of proved
reserves and a discount factor more representative of the time value of money
and the risks inherent in producing oil and gas.
 
ACQUISITIONS AND DIVESTITURES
 
     Several years ago, the Company embarked on an asset management program to
sell "non-core" properties and invest the proceeds into core operating areas
around the world in order to focus financial resources and personnel on the
Company's core areas of operation. Over the past three years, the Company has
sold properties, either as a strategic exit or by asset rationalization in
existing core areas, with proceeds totaling $216 million. Reserves associated
with these sales and trades are 47.7 MMEEBs, resulting in unit proceeds of $4.53
per EEB. During the same time period, Anadarko has acquired through purchases
and trades 25.5 MMEEBs of proved reserves at a cash cost of $48 million, or
$1.88 per EEB.
     During 1996, Anadarko sold reserves of 18.7 MMEEBs, of which 17.7 MMEEBs
were attributed to the Company's interests in Indonesia. Total proceeds from
divestitures in 1996 amounted to $41 million or $2.19 per EEB. In 1996,
acquisitions of producing properties totaled $5.3 million and 1.1 MMEEBs, at a
cost of $4.72 per EEB. The largest acquisition was a package of properties in
the Oklahoma Panhandle portion of the Hugoton Embayment. This package includes
significant undeveloped acreage on which Anadarko plans to conduct a 3-D seismic
survey and drill wells in 1997.
     Total 1995 proceeds from divestitures were $66.6 million, which included
assets in north Texas and the Permian Basin of southeast New Mexico and west
Texas. Reserves sold equaled 11.9 MMEEBs, resulting in unit proceeds of $5.60
per EEB. The largest sale in 1995 was the Company's interest in 25
"non-strategic" fields to other operators for $56.8 million. In 1995, Anadarko
acquired 9.8 MMEEBs of reserves at a cost of $26 million, or $2.66 per EEB. The
largest acquisition was a package of properties in west Texas purchased from
Shell Western E&P. The Company also purchased for $9.5 million a water supply
system in west Texas which reduced operating costs and enabled expansions of
several important waterflood projects.
     During 1994, Anadarko sold assets in the Arkoma Basin, the Rocky Mountains
and all of the Company's Canadian holdings. Reserves associated with the 1994
sales and trades were 17.1 MMEEBs, with proceeds of about $109 million, or $6.40
per EEB.
 
PRODUCING PROPERTIES AND LEASES
 
     The Company owns 2,286 net producing oil wells and 1,892 net producing gas
wells worldwide. The following schedule shows the number of developed and
undeveloped acres in which Anadarko held interests at December 31, 1996.

REGULATORY MATTERS
 
ENVIRONMENTAL  The Company's oil and gas operations and properties are subject
to numerous federal, state and local laws and regulations relating to
environmental protection. These laws and regulations govern, among other things,
the amounts and types of substances and materials that may be released into the
environment, the issuance of permits in connection with drilling and production
activities, the discharge and disposition of waste materials, offshore oil and
gas operations, the reclamation and abandonment of wells and facility sites and
the remediation of contaminated sites. In addition, these laws and regulations
may impose substantial liabilities for the Company's failure to comply with them
or for any contamination resulting from the Company's operations.
     Anadarko takes the issue of environmental stewardship very seriously and
works diligently to comply with applicable environmental rules and regulations.
Compliance with environmental laws and regulations has not had a material
adverse effect on the Company's operations or financial condition in the past.
However, because environmental laws and regulations are becoming increasingly
more stringent, there can be no assurances that such laws and regulations or any
environmental law or regulation enacted in the future will not have a material
adverse effect on the Company's operations or financial condition.
     For a description of certain environmental proceedings in which the Company
is involved, see Note 16 of the Notes to Consolidated Financial Statements under
Item 8 of this Form 10-K.
 
OTHER  Regulatory agencies in certain states have authority to issue permits for
the drilling of wells, regulate the spacing of wells, prevent the waste of oil
and gas resources through proration and regulate environmental matters.
     Operations conducted by the Company on federal oil and gas leases must
comply with numerous regulatory restrictions, including various
nondiscrimination statutes. Additionally, certain operations must be conducted
pursuant to appropriate permits issued by the Bureau of Land Management and the
Minerals Management Service of the Department of Interior and, with regard to
certain federal leases, with prior approval of drill site locations by the
Environmental Protection Agency. In addition to the standard permit process,
federal leases may require a complete environmental impact assessment prior to
authorizing an exploration or development plan.
 
ADDITIONAL FACTORS AFFECTING BUSINESS
 
COMMODITY PRICING AND DEMAND  Crude oil prices continue to be affected by
political developments worldwide, pricing decisions of the Organization of
Petroleum Exporting Countries (OPEC) and the volatile trading patterns in the
commodity futures markets. Natural gas prices also continue to be highly
volatile. In periods of sharply lower commodity prices, the Company may curtail
capital spending projects and delay or defer drilling wells in certain areas
because of lower cash flows. Changes in crude oil and natural gas prices can
impact the Company's determination of proved reserves and the Company's
calculation of the standardized measure of discounted future net cash flows
relating to oil and gas reserves. In addition, demand in the United States and
worldwide may affect the Company's level of production.
 
EXPLORATION AND OPERATING RISKS  The Company's business is subject to all of the
operating risks normally associated with the exploration for and production of
oil and gas, including blowouts, cratering and fire, each of which could result
in damage to or destruction of oil and gas wells or formations or production
facilities and other property and injury to persons. As protection against
financial loss resulting from these operating hazards, the Company maintains
insurance coverage, including certain physical damage, employer's liability,
comprehensive general liability and workmen's compensation insurance. Although
Anadarko is not fully insured against all risks in its business, the Company
believes that the coverage it maintains is customary for companies engaged in
similar operations. The occurrence of a significant event against which the
Company is not fully insured could have a material adverse effect on the
Company's financial position.
 
DEVELOPMENT RISKS  The Company is increasingly involved in large development
projects in the Gulf of Mexico, Alaska and internationally. Key factors that may
affect the timing and outcome of such projects include: project approvals by
joint-venture partners; timely issuance of permits and licenses by host country
governmental agencies; manufacturing and delivery schedules of critical
equipment; and commercial arrange-
 
                                       26
<PAGE>   28
 
ments for pipelines and related equipment to transport and market hydrocarbons.
In large development projects, these uncertainties are usually resolved, but
delays and differences between estimated timing and actual timing of critical
events are commonplace and may, therefore, affect the forward-looking statements
related to large development projects.
 
DOMESTIC GOVERNMENTAL RISKS  The domestic operations of the Company have been,
and at times in the future may be, affected by political developments and by
federal, state and local laws and regulations such as restrictions on
production, changes in taxes, royalties and other amounts payable to governments
or governmental agencies, price or gathering rate controls and environmental
protection regulations.
 
FOREIGN OPERATIONS RISK  The Company's operations in areas outside the United
States are subject to various risks inherent in foreign operations. These risks
may include, among other things, loss of revenue, property and equipment as a
result of hazards such as expropriation, war, insurrection and other political
risks, increases in taxes and governmental royalties, renegotiation of contracts
with governmental entities, changes in laws and policies governing operations of
foreign-based companies, currency restrictions and exchange rate fluctuations
and other uncertainties arising out of foreign government sovereignty over the
Company's international operations. The Company's international operations may
also be adversely affected by laws and policies of the United States affecting
foreign trade and taxation. To date, the Company's international operations have
not been materially affected by these risks.
 
COMPETITION  The oil and gas business is highly competitive in the search for
and acquisition of reserves, as well as, in the gathering and marketing of oil
and gas production. The Company's competitors include the major oil companies,
independent oil and gas concerns, individual producers, gas marketers and major
pipeline companies, as well as participants in other industries supplying energy
and fuel to industrial, commercial and individual consumers. Competition for
drilling rigs is keen in certain areas of the Gulf of Mexico. During 1996 and
1995, the Company experienced increases in drilling rig rental rates due to the
tight rig market in the Gulf of Mexico.
 
CAPITAL EXPENDITURES, LIQUIDITY AND LONG-TERM DEBT
 
CAPITAL EXPENDITURES  Anadarko's total capital spending in 1996 was $427
million, an increase of 29 percent over a 1995 capital spending level of $331
million and about equal to 1994 spending of $423 million. Capital spending in
1996 did not reach the budget initially set at $485 million, largely due to
construction delays in Algeria. The 1995 spending level was lower than
originally anticipated due to lower gas prices and deferred drilling
opportunities in the Gulf of Mexico's sub-salt play. The 1994 spending included
$72 million to acquire 26 offshore lease blocks in the Gulf of Mexico at the
Minerals Management Service Offshore Lease Sale No. 147 in March 1994. The
largest categories of capital spending in 1996, 1995 and 1994 were for
exploration and development activities in the U.S. and overseas. The Company
funded its capital investment program in 1996, 1995 and 1994 primarily through
cash flow, plus proceeds from property sales and increases in long-term debt.

</TABLE>
 
     Capital spending for 1997 has been set at about $560 million, an increase
of 31 percent over 1996 and the highest anticipated spending level in Company
history. The higher capital budget is driven by increased
 
                                       27
<PAGE>   29
 
opportunities in both U.S. and international exploration and development
drilling programs. The 1997 budget includes $159 million for exploration, $300
million for development, $27 million for gathering and other, and $74 million
for capitalized interest and overhead. Although no dollars are budgeted for
acquisitions in 1997, the Company will look at opportunities and, depending on
conditions of the market, may elect to purchase properties.
     Historically, the Company has based capital spending on anticipated cash
flows including proceeds from divestitures, but certain portions of the capital
spending budget -- such as acquisitions -- have been financed from time to time.
In addition, the Company's budget is adjusted periodically to reflect changes in
market prices for oil and natural gas. The Company believes cash flows,
including proceeds from divestitures, and existing credit facilities will be
sufficient to meet capital and operating requirements, including any
contingencies, during 1997.
 
LIQUIDITY AND LONG-TERM DEBT  At year-end 1996, Anadarko's total debt was $731
million. This compares to year-end 1995 total debt of $674 million.
     In January 1997, the Company entered into a sale/lease back agreement for
$88.4 million involving 145 natural gas compressors in Anadarko's major
mid-continent gathering systems. The transaction monetized Company assets and
took advantage of current low interest rates. Proceeds from the transaction were
used for general corporate purposes.
     During 1996, Anadarko offered two "Century Bonds". In September 1996, the
Company issued $100 million principal amount of 7.73% Debentures due 2096. Each
Debenture holder has the one-time right to have the Company purchase on
September 15, 2026, all or a portion of, the Debentures, at a purchase price
equal to par plus accrued and unpaid interest. In November 1996, the Company
issued $100 million principal amount of 7 1/4% Debentures due November 15, 2096.
     During the fourth quarter of 1996, Anadarko entered into a 10-year swap
agreement with a notional value of $100 million whereby the Company receives a
fixed interest rate and pays a floating interest rate indexed to 3-month LIBOR.
This agreement was entered into to offset a portion of the effect of the
Company's fixed-rate long-term debt financed in 1996.
     In March 1995, Anadarko issued $100 million principal amount of 7 1/4%
Debentures due 2025. Each Debenture holder has the one-time right to have the
Company purchase on March 15, 2000, all or a portion of, the Debenture at a
purchase price equal to par plus accrued and unpaid interest.
     In May 1994, Anadarko entered into a $250 million Revolving Credit
Agreement and a $150 million 364-Day Credit Agreement with a group of commercial
banks. As of December 31, 1996 and 1995, there were no outstanding borrowings
under these agreements.
     In May 1995, the Company issued one million shares of common stock to the
Anadarko Petroleum Corporation Executives and Directors Benefits Trust (Trust)
to secure present and future unfunded benefit obligations of the Company. The
shares issued to the Trust are not considered outstanding for quorum or voting
calculations, but the Trust will receive dividends. The shares are included in
the calculation of earnings per share under the treasury stock method and have
no dilutive effect.
     Anadarko's net cash from operating activities in 1996 was up 27 percent to
$315 million compared to $248 million in 1995. Net cash from operating
activities in 1994 was $240 million.
 
CHANGES IN ACCOUNTING PRINCIPLES
 
STOCK-BASED COMPENSATION  Statement of Financial Accounting Standards (SFAS) No.
123, "Accounting for Stock-based Compensation" defines a fair value based method
of accounting for an employee stock option or similar equity instrument. SFAS
No. 123 allows an entity to continue to measure compensation costs for these
plans using the current method of accounting. Anadarko has elected to continue
to use the current method of accounting for employee stock compensation plans
and discloses in Note 7 of the Notes to the Consolidated Financial Statements
under Item 8 of this Form 10-K, the fair value as defined in SFAS No. 123.

DIVIDENDS
 
     In 1996, Anadarko paid $17.8 million in dividends to its common
stockholders (7.5 cents per share per quarter). The dividend amount was $17.7
million in 1995 (7.5 cents per share per quarter) and $17.6 million (7.5 cents
per share per quarter) in 1994. Anadarko has paid a dividend continuously since
becoming an independent company in 1986.
     The Revolving Credit Agreement and the 364-Day Credit Agreement require a
minimum balance of $650 million to be maintained in retained earnings. As a
result, the amount of retained earnings available for dividends as of December
31, 1996 was $364.1 million. The amount of future dividends will depend on
earnings, financial condition, capital requirements and other factors, and will
be determined by the Board of Directors on a quarterly basis.

                              REPORT OF MANAGEMENT
 
     The management of Anadarko Petroleum Corporation is responsible for the
preparation and integrity of all information contained in the accompanying
consolidated financial statements. The financial statements have been prepared
in conformity with generally accepted accounting principles appropriate in the
circumstances. In preparing the financial statements, management makes informed
judgements and estimates.
     Management maintains and relies on the Company's system of internal
accounting controls. Although no system can ensure elimination of all errors and
irregularities, this system is designed to provide reasonable assurance that
assets are safeguarded, transactions are executed in accordance with
management's authorization and accounting records are reliable as a basis for
the preparation of financial statements. This system includes the selection and
training of qualified personnel, an organizational structure providing
appropriate delegation of authority and division of responsibility, the
establishment of accounting and business policies for the Company and the
conduct of internal audits.
     The Board of Directors pursues its responsibility for the consolidated
financial information through its Audit Committee, which is composed solely of
directors who are not officers or employees of Anadarko. The Audit Committee
recommends to the Board of Directors the selection of independent auditors and
reviews their fee arrangements. The Audit Committee meets periodically with
management, the internal auditors and the independent auditors to review that
each is carrying out its responsibilities. The internal and independent auditors
have full and free access to the Audit Committee to discuss auditing and
financial reporting matters.
     We believe that Anadarko's policies and procedures, including its system of
internal accounting controls, provide reasonable assurance that the financial
statements are prepared in accordance with the applicable securities laws.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Anadarko Petroleum Corporation:
 
     We have audited the accompanying consolidated balance sheets of Anadarko
Petroleum Corporation and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the years in the three-year period ended December 31, 1996, as
contained in the 1996 Form 10-K Annual Report. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Anadarko
Petroleum Corporation and subsidiaries as of December 31, 1996 and 1995, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996, in conformity with generally accepted
accounting principles.

                         ANADARKO PETROLEUM CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
 
1.  SUMMARY OF ACCOUNTING POLICIES
 
GENERAL  Anadarko Petroleum Corporation is engaged in the exploration,
development, production and marketing of natural gas, crude oil, condensate and
natural gas liquids (NGLs). The terms "Anadarko" and "Company" refer to Anadarko
Petroleum Corporation and its subsidiaries. The principal subsidiaries of
Anadarko are: Anadarko Gathering Company; Anadarko Energy Services Company
(formerly Anadarko Trading Company); and, Anadarko Algeria Corporation (Anadarko
Algeria). In December 1994, the Company sold its wholly-owned subsidiary,
Anadarko Petroleum of Canada Ltd. (Anadarko Canada). See Note 2.
 
PRINCIPLES OF CONSOLIDATION AND USE OF ESTIMATES  The consolidated financial
statements include the accounts of Anadarko and its subsidiaries. All
significant intercompany transactions have been eliminated. The financial
statements have been prepared in conformity with generally accepted accounting
principles appropriate in the circumstances. Certain amounts for prior years
have been restated to conform to the current presentation. In preparing
financial statements, management makes informed judgements and estimates that
affect the reported amounts of assets and liabilities as of the date of the
financial statements and affect the reported amounts of revenues and expenses
during the reporting period. Actual results may differ from these estimates.
 
REVENUES  Natural gas revenues generally are recorded using the sales method,
whereby the Company recognizes natural gas revenues based on the amount of gas
sold to purchasers on its behalf. All other revenues also are recorded using the
sales method.
 
PRICE RISK MANAGEMENT  Anadarko's financial instruments currently are comprised
of futures, swaps and options. Anadarko uses commodity derivative financial
instruments to minimize the impact of price fluctuations for the Company and its
customers. To qualify as a hedge, these instruments must correlate to
anticipated future sales such that the Company's exposure to the effects of
commodity price changes is reduced. The gains and losses on these instruments
are included in the valuation of the transactions being hedged upon completion
of the transactions. Gains and losses on derivatives not classified as hedges
are accounted for on a current basis. Unrealized gains and losses are recorded
as assets and liabilities on the balance sheet. See Note 6.
 
PROPERTIES AND EQUIPMENT  The Company uses the full cost method of accounting
for exploration and development activities as defined by the United States
Securities and Exchange Commission (SEC). Under this method of accounting, the
costs for unsuccessful, as well as successful, exploration and development
activities are capitalized as properties and equipment. This includes any
internal costs that can be directly identified with acquisition, exploration and
development activities, but does not include any costs related to production,
general corporate overhead or similar activities.
     The sum of net capitalized costs and estimated future development and
dismantlement costs is amortized using the unit-of-production method. Excluded
from amounts subject to amortization are costs associated with unevaluated
properties and major development projects. On a country-by-country basis, should
the net capitalized costs exceed the estimated present value of future net cash
flows from proved oil and gas reserves, such excess costs would be charged to
current expense. Gain or loss on the sale or other disposition of oil and gas
properties is not recognized unless significant amounts of oil and gas reserves
are involved.
     Unsuccessful geothermal exploration costs are charged to expense. All other
properties and equipment are stated at original cost, which does not purport to
represent replacement or market values.
 
ENVIRONMENTAL CONTINGENCIES  The Company accrues for environmental contingencies
when liabilities are likely to occur and reasonable estimates can be made. In
accordance with full cost accounting rules, the Company provides for
environmental clean up costs associated with oil and gas activities as a
component of its depreciation, depletion and amortization expense. Recoveries
from third parties for environmental liabilities are not recognized unless
collection is probable.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
 
1.  SUMMARY OF ACCOUNTING POLICIES -- (CONTINUED)
INTEREST CAPITALIZED  The Company capitalizes interest on borrowed funds related
to oil and gas expenditures that are not subject to amortization until
completion of evaluation or development activities.
 
INCOME TAXES  The Company, excluding Anadarko Canada, files a U.S. consolidated
federal income tax return. Deferred federal and state income taxes are provided
on all significant temporary differences, except for those essentially permanent
in duration, between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases.
 
FOREIGN CURRENCY TRANSLATION ADJUSTMENTS  The financial statements of Anadarko
Canada were translated to U.S. dollars. All balance sheet accounts were
translated at the current exchange rate and income statement items were
translated at the average exchange rate for the year; resulting translation
adjustments were made directly to a separate component of stockholders' equity.
Transaction adjustments were reported in net income. In prior years, deferred
federal income taxes were not provided on translation adjustments because the
earnings of Anadarko Canada were considered to be permanently invested. Due to
the sale of Anadarko Canada in 1994, the cumulative foreign currency translation
losses were transferred from stockholders' equity and included in disposition of
foreign subsidiary on the income statement. See Note 2.
 
CASH EQUIVALENTS  The Company considers all highly liquid investments purchased
with an original maturity of three months or less to be cash equivalents.
 
ACCOUNTS PAYABLE, BANKS  This account represents credit balances to the extent
that checks issued have not been presented to the Company's banks for payment.
 
STOCK-BASED COMPENSATION  Effective January 1, 1996, Anadarko adopted Statement
of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-based
Compensation". SFAS No. 123 defines a fair value method of accounting for an
employee stock option or similar equity instrument. SFAS No. 123 allows an
entity to continue to measure compensation costs for these plans using the
current method of accounting. Anadarko has elected to continue to use the
current method of accounting for employee stock compensation plans and disclose
the fair values as defined in SFAS No. 123. See Note 7.
 
2.  DISPOSITION OF FOREIGN SUBSIDIARIES
 
     In September 1996, Anadarko sold its wholly-owned subsidiary, Anadarko
Indonesia Company, Jabung. As a result, the Company recorded a gain of
$19,385,000 and U.S. income tax expense of $7,040,000 on the sale.
     In December 1994, Anadarko sold Anadarko Canada for $57,937,000. In
connection with the sale, Anadarko recorded a charge of $5,567,000 before income
taxes ($6,635,000 after income taxes) primarily due to a non-cash charge of
$6,065,000 for cumulative foreign currency translation losses previously
recorded as a reduction in stockholders' equity. The Company recorded U.S.
income tax expense of $17,454,000 on the sale. The Company also reversed
previously provided deferred Canadian taxes in the amount of $16,386,000 for a
net income tax expense associated with the sale of $1,068,000.
 
3.  CASH AND CASH EQUIVALENTS
 
     As of December 31, 1996 and 1995, cash and cash equivalents included
$321,000 and $222,000, respectively, held by the Executives and Directors
Benefits Trust. In addition, as of December 31, 1995, cash and cash equivalents
included $4,127,000 invested in U.S. Treasury securities, which the Company had
dedicated for a "like-kind" property exchange.

</TABLE>
 
     Oil and gas properties are amortized using the unit-of-production method.
All other properties are depreciated on the straight-line basis over the useful
lives of the assets, which range from three to 25 years.
     Oil and gas properties include costs of $254,811,000 and $245,577,000 at
December 31, 1996 and 1995, respectively, which were excluded from capitalized
costs being amortized. These amounts represent costs associated with unevaluated
properties and major development projects. Anadarko excludes all costs on a
country-by-country basis until proved reserves are found or until it is
determined that the costs are impaired. All excluded costs are reviewed
quarterly to determine if impairment has occurred.
     Properties and equipment include costs of $231,858,000 and $146,706,000 at
December 31, 1996 and 1995, respectively, for the Company's exploration and
development activities in Algeria. Depreciation of these assets will begin when
production commences.
     During 1996, 1995 and 1994, the Company made provisions for impairments of
international properties of $5,400,000, $600,000 and $3,100,000, respectively,
which were related to oil and gas properties. These impairments related to
projects that the Company has decided not to pursue in China and various other
international locations. During 1995, the Company made a provision for
impairments of geothermal properties of $2,000,000.
     Total interest costs incurred during 1996, 1995 and 1994 were $55,985,000,
$52,557,000 and $41,635,000, respectively. Of these amounts, the Company
capitalized $17,012,000, $16,199,000 and $15,507,000 during 1996, 1995 and 1994,
respectively. Capitalized interest is included as part of the cost of oil and
gas properties. The capitalization rates are based on the Company's weighted
average cost of borrowings used to finance the expenditures.
     In addition to capitalized interest, the Company also capitalized internal
costs of $50,213,000, $40,617,000 and $37,898,000 during 1996, 1995 and 1994,
respectively. These internal costs were directly related to acquisition,
exploration and development activities and are included as part of the cost of
oil and gas properties.

*The average rates in effect at December 31, 1996 and 1995 were 6.30% and 5.96%,
 respectively for the Commercial Paper. The average rate in effect at December
 31, 1995 was 5.95% for the Notes Payable, Banks.
 
     Anadarko has noncommitted lines of credit from several banks. The general
provisions of these lines of credit provide for Anadarko to borrow funds for
terms and rates offered from time to time by the banks. There are no fees
associated with these lines of credit.
     The Company has a commercial paper program that allows Anadarko to borrow
funds, at rates as offered, by issuing notes to investors for terms of up to 270
days.
     The commercial paper and notes payable to banks in 1996 and 1995 have been
classified as long-term debt in accordance with SFAS No. 6, "Classification of
Short-term Obligations Expected to be Refinanced," under the terms of Anadarko's
Bank Credit Agreements.
     In November 1996, Anadarko issued $100,000,000 principal amount of 7 1/4%
Debentures due 2096. The Company has a conditional right to shorten the maturity
of the Debentures if tax law changes impact the tax deduction for interest on
the Debentures. Net proceeds from the offering were used to repay floating
interest rate debt.
     In September 1996, Anadarko issued $100,000,000 principal amount of 7.73%
Debentures due 2096. Each Debenture holder has the one-time right to have the
Company purchase on September 15, 2026, all or a portion of, the Debentures at a
purchase price equal to par plus accrued and unpaid interest. Net proceeds from
the offering were used to repay floating interest rate debt.
     In March 1995, Anadarko issued $100,000,000 principal amount of 7 1/4%
Debentures due 2025. Each Debenture holder has the one-time right to have the
Company purchase on March 15, 2000, all or a portion of, the Debentures at a
purchase price equal to par plus accrued and unpaid interest. Net proceeds from
the offering were used to repay floating interest rate debt.
     In May 1994, the Company entered into a $250,000,000 Revolving Credit
Agreement and a $150,000,000 364-Day Credit Agreement with a group of 11
commercial banks. In May 1996, the Agreements were amended to reduce the
commitment fees and extend the expiration date of the Agreements for one year.
Interest rates are based on either the reference rate, the rate of certificate
of deposit, the Eurodollar rate or a combination thereof. The Agreements provide
for commitment fees on the unused balances at a rate of 12.5/100 of one percent
and 10.0/100 of one percent for the Revolving Credit Agreement and 364-Day
Credit Agreement, respectively. The Revolving Credit Agreement will expire in
2001. During 1996 and 1995, there were no outstanding borrowings under these
Agreements.

6.  LONG-TERM DEBT AND FINANCIAL INSTRUMENTS -- (CONTINUED)
     During 1996 and 1995, the Company had available $20,000,000 in a bank line
of credit which was not used. The maximum interest rate for loans against the
line was the reference rate of the bank. The line of credit is renewable
annually, but may be withdrawn at any time by the bank. In 1996 and 1995,
Anadarko maintained an average daily compensating balance of $1,000,000 for this
line of credit.
     Total sinking fund and installment payments related to long-term debt for
the five years ending December 31, 2001 are shown below. The payments related to
the redemption of the commercial paper are included in the amounts shown in a
manner consistent with the terms for repayment of the Revolving Credit
Agreement.

CASH AND CASH EQUIVALENTS  The carrying amount reported on the balance sheet
approximates fair value.
 
LONG-TERM DEBT  The fair value of long-term debt at December 31, 1996 and 1995
is the value the Company would have to pay to retire the debt, including any
premium or discount to the debt holder for the differential between stated
interest rate and year-end market rate. The fair values are based on quoted
market prices from Standard & Poor's Bond Guide and, where such quotes were not
available, on the average rate in effect at year-end.
 
COMMODITY DERIVATIVE FINANCIAL INSTRUMENTS  Anadarko uses commodity derivative
financial instruments -- futures, swaps and options -- to fix a price
independent of the timing of the physical purchase or sale, to fix a price
differential (basis) between the price of gas at Henry Hub and the price at the
market locations at which Anadarko purchases and sells oil and gas (market
locations), to hedge the fixed price or fixed basis pricing requirements of
Anadarko's customers and suppliers, and to hedge the value of gas in storage or
gas owed to or due from pipelines. Gains and losses generally are recorded when
the related gas or oil production has been

6.  LONG-TERM DEBT AND FINANCIAL INSTRUMENTS -- (CONTINUED)
produced or delivered. As a result, gains and losses are generally offset by
similar changes in the price of natural gas and crude oil. Unrealized gains and
losses are recorded as assets and liabilities on the balance sheet at fair
market value as of the balance sheet date. The unrealized gains and losses
include derivatives related to January activities deferred as of December 31 and
exclude certain written options recognized during the year. All volumes exclude
January hedges not open and written options recognized. While financial
instruments are intended to reduce the Company's exposure to declines in the
market price of natural gas and crude oil, the financial instruments may limit
Anadarko's gain from increases in the market price of natural gas and crude oil.
The fair value of derivative financial instruments reflects the estimated
amounts that the Company would receive or pay to settle the contracts as of
December 31. Dealer quotes are available for the majority of the Company's
derivatives.
 
COMMODITY FUTURES  Anadarko generally uses commodity futures contracts to fix
the price of gas delivered to Henry Hub or oil delivered to Cushing. Futures
contracts have settlement guaranteed by the New York Mercantile Exchange (NYMEX)
and have nominal credit risk.
     At year-end 1996, Anadarko had open natural gas futures contracts totaling
76 billion British thermal units per day (BBtu/d) related to sales for February
through March 1997. The Company had open natural gas futures contracts related
to gas owed to pipelines of 15 BBtu/d for April through May 1997. Anadarko had
open crude oil futures contracts related to sales of 6 thousand barrels per day
(MBbls/d) for February 1997.
     At year-end 1995, Anadarko had open natural gas futures contracts totaling
66 BBtu/d related to sales for February through March 1996. The Company had open
natural gas futures contracts related to sales of 14 BBtu/d for April through
November 1996. The Company had open natural gas futures contracts related to
customer and supplier pricing requirements of 1.3 BBtu/d for February through
March 1996. Anadarko had open crude oil futures contracts related to sales of
3.4 MBbls/d for February 1996.
 
COMMODITY SWAPS  Anadarko generally uses commodity swap agreements with
third-parties to fix the price of gas and oil at its market locations. In
addition, Anadarko uses basis swap agreements to fix the price differential
between the price of gas at Henry Hub and the price of gas at its market
locations. These energy swap agreements expose the Company to third-party credit
risk to the extent the third-parties are unable to meet their monthly settlement
commitment to the Company. The Company monitors the credit standing of the
third-parties and anticipates they will be able to fully satisfy their
contractual obligations.
     At year-end 1996, Anadarko had open basis swap agreements for the Company's
gas sales averaging 30 BBtu/d for 1997, 1998 and 1999 which were offset by open
basis swap agreements of like amounts for the same periods, thus eliminating the
risk to Anadarko from future price changes related to this position. The Company
had open gas basis swap agreements related to sales averaging 270 BBtu/d for
February through March 1997 and 70 BBtu/d for April through July 1997. In
addition, the Company had basis swaps related to customer and supplier gas
pricing requirements of 8 BBtu/d for February through March 1997 and related to
gas owed to pipelines of 15 BBtu/d for April through May 1997.
     At year-end 1995, Anadarko had open basis swap agreements for the Company's
gas sales averaging 64 BBtu/d for January through December 1996 and 30 BBtu/d
for 1997, 1998 and 1999, which were offset by open basis swap agreements of like
amounts for the same periods, thus eliminating the risk to Anadarko from future
price changes related to these two positions. The Company also had open gas swap
agreements related to sales averaging 7 BBtu/d for February through December
1996 and related to customer and supplier gas pricing requirements of 9 BBtu/d
for February through December 1996.
 
COMMODITY OPTIONS  The Company generally uses commodity options to fix a floor
and a ceiling for prices (a "collar") on its sales volumes. The Company also has
used options to "straddle" a price, effectively setting a price above the then
present market price at which the Company is willing to fix its sales price and
a price below the then present market price at which the Company is willing to
fix its purchase price for third party supply. Like futures, NYMEX options have
settlement guaranteed and have nominal credit risk. Over-the-counter (OTC)
options with third-parties have credit risks similar to swaps.

6.  LONG-TERM DEBT AND FINANCIAL INSTRUMENTS -- (CONTINUED)
     At year-end 1996, Anadarko had open NYMEX options for the Company's gas
sales of 10 BBtu/d for puts and 16 BBtu/d for calls during February and March
1997 and 30 BBtu/d for both puts and calls during April through July 1997.
Anadarko also had open NYMEX gas options for its customers of 30 BBtu/d for puts
and 6 BBtu/d for calls for February through March 1997. In addition, the Company
had open crude oil options on 5.1 MBbls/d for both puts and calls during
February through April 1997.
     At year-end 1995, Anadarko had open NYMEX options for the Company's gas
sales of 183 BBtu/d for puts and 61 BBtu/d for calls during February through
March 1996 and 30 BBtu/d for puts and 20 BBtu/d for calls for April through
November 1996 in order to fix a price range on gas sales. In addition, the
Company had open crude oil options on 1.7 MBbls/d for puts and 4.5 MBbls/d for
calls during February through March 1996.
 
INTEREST RATE SWAPS  During the fourth quarter of 1996, Anadarko entered into a
10-year swap agreement with a notional value of $100,000,000 whereby the Company
receives a fixed interest rate and pays a floating interest rate indexed to
3-month LIBOR. This agreement was entered into to offset a portion of the effect
of the Company's fixed rate long-term debt financed in 1996.
     In October 1993, Anadarko accepted a payment of $2,600,000 granting the
purchaser the option to enter into a nine-year interest rate swap agreement with
the Company. The option was exercisable in October 1994. This agreement, if
exercised, would have effectively fixed the rate the Company would have paid on
a notional $100,000,000 of its floating interest rate debt at six percent for
nine years. The $2,600,000 payment and the related agreement hedged the
Company's floating interest rate debt. The option was not exercised and, as a
result, the Company recorded a reduction to interest expense of $2,600,000
during the fourth quarter of 1994.

7.  STOCK AND STOCK OPTIONS -- (CONTINUED)
dividends by the Company, retained earnings of $364,080,000, $259,694,000 and
$249,599,000 were not restricted as to the payment of dividends at December 31,
1996, 1995 and 1994, respectively.
     During 1996, 1995 and 1994, the Company acquired treasury stock only as a
result of stock option exercises, restricted stock transactions or buyback of
shares, which were unsolicited from stockholders.
     In May 1995, the Company issued 1,000,000 shares of common stock to the
Anadarko Petroleum Corporation Executives and Directors Benefits Trust (Trust)
to secure present and future unfunded benefit obligations of the Company. The
shares issued to the Trust are not considered outstanding for quorum or voting
calculations, but the Trust will receive dividends. The shares are included in
the calculation of earnings per share under the treasury stock method and have
no dilutive effect. The fair market value of these shares is included in common
stock and paid-in capital and as a reduction to stockholders' equity. As of
December 31, 1996 and 1995, there were 1,000,000 shares in the Trust.
     Anadarko has four stock option plans -- the 1993 Stock Incentive Plan, the
1988 Stock Option Plan for Non-employee Directors, the 1987 Stock Option Plan
and the 1986 Stock Option Plan -- under which key employees and directors of the
Company may be granted options to purchase shares of Anadarko common stock.
Incentive stock options and non-qualified stock options have a maximum term of
eleven years from the date of grant and are issued at the market value of
Anadarko stock on the date of grant. The options vest over time and may be
exercised no earlier than one year from the date of grant.
     In addition, the 1993 Stock Incentive Plan and the 1987 Stock Option Plan
provide that up to 800,000 and 400,000 shares of common stock, respectively,
which may be granted under the Plans, may be granted as restricted stock.
Generally, restricted stock is subject to forfeiture restrictions and cannot be
sold, transferred or disposed of during the restriction period. The holders of
the restricted stock have all the rights of a stockholder of the Company with
respect to such shares, including the right to vote and receive dividends or
other distributions paid with respect to such shares. During 1996, 1995 and
1994, the Company issued 39,450, 26,950 and 31,950 shares, respectively, of
restricted stock with a weighted-average grant date fair value of $63.42, $41.04
and $52.21, respectively.
     In 1996, Anadarko and a key officer of the Company entered into a
Performance Share Agreement under the 1993 Stock Incentive Plan. The Agreement
provides for issuance of up to 150,000 shares of common stock of the Company at
the end of a four or eight-year period contingent upon the Company's achievement
of predetermined objectives. During the year ended December 31, 1996, expense of
$2,000,000 was recognized under the Agreement. The fair value of the performance
shares is not determinable at this time since the shares to be issued are
contingent upon the Company's achievement of the objectives.

7.  STOCK AND STOCK OPTIONS -- (CONTINUED)
     SFAS No. 123 "Accounting for Stock-based Compensation" defines a fair value
method of accounting for an employee stock option or similar equity instrument.
SFAS No. 123 allows an entity to continue to measure compensation costs for
these plans using the current method of accounting. Anadarko has elected to
continue the current method of accounting for employee stock compensation plans.
Anadarko applies Accounting Principles Board (APB) Opinion No. 25 and related
interpretations in accounting for its stock option plans. Accordingly, no
compensation expense is recognized for stock options granted with an exercise
price equal to the market value of Anadarko stock on the date of grant. If
compensation expense for the Company's stock option plans had been determined
using the fair-value method in SFAS No. 123, the Company's net income and
earnings per share would have been as shown in the pro forma amounts below:

10.  TRANSACTIONS WITH RELATED PARTIES AND MAJOR CUSTOMERS
 
     During 1989, Anadarko Algeria entered into a Production Sharing Agreement
(PSA) with SONATRACH, the national oil and gas enterprise of Algeria. SONATRACH
is the beneficial owner of 10.1 percent of the Company's outstanding common
stock. The PSA gives Anadarko Algeria the right to explore for and produce
liquid hydrocarbons in Algeria, subject to the sharing of production with
SONATRACH. Anadarko Algeria has two partners in the PSA. During 1994, the
Company acquired a minority interest in a PSA covering two additional blocks in
the same region, which are operated by BHP Petroleum (Algerie) Inc., where an
exploration program is already underway. Approximately $60,000, $432,000 and
$30,000 was paid to SONATRACH in 1996, 1995 and 1994, respectively, for charges
related to reservoir studies, laboratory services, well testing services and
equipment usage. The Company believes anticipated operating cash flows

and existing credit facilities will be sufficient to meet its share of the
exploration and development costs. As of December 31, 1996, Anadarko Algeria's
total net investment in Algeria for exploration, development and related
activities was $231,858,000, of which approximately $85,152,000 was incurred in
1996.
     In September 1996, Anadarko and its partners signed a $177 million
Engineering, Procurement and Construction (EPC) contract with Brown & Root
Condor, a company jointly owned by Brown & Root and affiliates of SONATRACH. For
the year ended December 31, 1996, approximately $21,933,000 was paid to Brown &
Root Condor under the EPC contract.
     Political unrest exists in Algeria. Anadarko is closely monitoring the
situation and has taken reasonable and prudent steps to ensure the safety of
employees working in the remote regions of the Sahara Desert. Anadarko is
presently unable to predict with certainty any effect the current situation may
have on activity planned for 1997 and beyond. However, the situation has not had
any material effect on the Company's operations. The Company's activities in
Algeria also are subject to the general risks associated with all foreign
operations.
     In 1996, the Company paid $878,000 to Petroleum Information Corporation and
its subsidiaries for production, drilling and seismic data. Also in 1996, the
Company paid Houston Advanced Research Center (HARC) $50,000 for a seismic
imaging project. John R. Butler, Jr., a director of the Company, serves as
Senior Chairman for Petroleum Information Corporation and Chairman for HARC.
     The Company's natural gas is sold to interstate and intrastate gas
pipelines, direct end-users, industrial users, local distribution companies and
gas marketers. Crude oil and condensate are sold to marketers, gatherers and
refiners. NGLs are sold to direct end-users, refiners and marketers. These
purchasers are located in the United States, Canada and Mexico. The majority of
the Company's receivables are paid within two months following the month of
purchase.
     The Company generally performs a credit analysis of customers prior to
making any sales to new customers. Based upon this credit analysis, the Company
may require a standby letter of credit or a financial guarantee.
     In 1996, sales to Texaco Trading & Transportation Company were $64,444,000,
which accounted for more than ten percent of the Company's total revenues. In
1995, sales to Indiana Gas Company Incorporated were $53,130,000 and sales to
Texaco Trading & Transportation Company were $53,092,000, each of which
accounted for more than ten percent of the Company's total revenues. In 1994,
sales to Indiana Gas Company Incorporated were $67,348,000, which was more than
ten percent of the Company's total revenues.

13.  INCOME TAXES -- (CONTINUED)
     The tax benefit of compensation expense for tax purposes in excess of
amounts recognized for financial accounting purposes has been credited directly
to stockholders' equity. For 1996, 1995 and 1994 the tax benefit amounted to
$5,055,000, $458,000 and $968,000, respectively.
     The tax effects of temporary differences that give rise to significant
portions of the deferred tax liabilities (assets) at December 31, 1996 and 1995
are as follows:

     The Company has determined that it is more likely than not that the
deferred tax assets will be realized and a valuation allowance for such assets
is not required.
     In December 1994, the Company sold Anadarko Canada. Under current
accounting rules, Anadarko had not previously provided deferred U.S. income
taxes on the amount by which its investment in Anadarko Canada exceeded the tax
basis or on the cumulative foreign currency translation losses because these
temporary differences were previously considered permanent in duration. See Note

14.  LEASE COMMITMENTS
 
     The Company has various commitments under non-cancelable operating lease
agreements for buildings, facilities and equipment, the majority of which expire
at various dates through 2014. The leases are expected to be renewed or replaced
as they expire. At December 31, 1996, future minimum rental payments due under

15.  PENSION PLANS, EMPLOYEE SAVINGS PLAN AND OTHER POSTRETIREMENT BENEFITS
 
PENSION PLANS  The Company has a non-contributory defined benefit pension plan
covering all permanent employees, except certain employees in foreign countries.
The benefits for this plan are based primarily on years of service and pay near
retirement. Plan assets consist principally of fixed income investments and
equity securities. The Company funds the plan with annual contributions as
determined in accordance with the Employee Retirement Income Security Act of
1974 and Internal Revenue Code of 1986, as amended, limitations.
     The Company has an equalization plan to ensure payments to certain
employees of amounts to which they are already entitled under the provisions of
the pension plan, but which are subject to limitations imposed by federal tax
laws. This plan is unfunded and payable solely from the general assets of the
Company. In addition, the Company has a pension plan for non-employee directors,
which is unfunded.
     The 1996, 1995 and 1994 pension cost related to these plans includes the
following components:

</TABLE>
 
     The special termination benefits incurred in 1994 relate to the closing of
several plant locations. The Company had an additional minimum liability of
$2,359,000 and $1,301,000 at December 31, 1996 and 1995, respectively, which
represents the difference between the unfunded accumulated benefit obligation
and the accrued pension cost related to the equalization plan. This liability
was offset by an intangible asset of an equal amount.

EMPLOYEE SAVINGS PLAN  The Company has an employee savings plan (ESP) that is a
defined contribution plan. The Company matches a portion of employees'
contributions with shares of the Company's common stock. Participation in the
ESP is voluntary and all regular employees of the Company are eligible to
participate. The Company charged to expense plan contributions of $4,076,000,
$3,731,000, and $3,579,000 during 1996, 1995 and 1994, respectively.
 
OTHER POSTRETIREMENT BENEFITS  In addition to providing pension benefits, the
Company provides certain health care and life insurance benefits for retired
employees. Substantially all of the Company's employees,

15.  PENSION PLANS, EMPLOYEE SAVINGS PLAN AND OTHER POSTRETIREMENT
BENEFITS -- (CONTINUED)
including employees in foreign countries, may become eligible for these benefits
if they reach retirement age while working for the Company. These benefits and
similar benefits for active employees are provided through contributory and
noncontributory benefit plans.
     Health care benefits are funded by contributions from the Company and its
employees, with retiree contributions adjusted per the provisions of the
Company's health care plans. The Company's current policy is to fund the cost of
postretirement health care benefits on a pay-as-you-go basis. The Company's
retiree life insurance plan is noncontributory and is currently fully funded
through insurance premiums paid by the Company.
     The following table sets forth the Company's postretirement benefits other
than pension combined liability as of December 31, 1996 and 1995:

</TABLE>
 
     The health care trend rate for the health care plans starts at the maximum
rate for the current year and is gradually reduced to an ultimate rate for 2001
and later years. A change in the health care trend rate of one percent would
change the annual cost in 1996 by approximately $674,000 and would change the
accumulated postretirement benefit obligation in 1996 by approximately
$5,472,000.

16.  CONTINGENCIES
 
ENVIRONMENTAL  On December 17, 1993, the Company received a notice from the
Department of Justice in the State of California indicating the Company may be a
potentially responsible party (PRP) for the study, cleanup and closure of the
waste facility owned by Geothermal, Inc. in Middletown, California (the GI
site). Anadarko's records indicate the disposal of a limited number of barrels
of drilling mud at the GI site in 1982. During the first quarter of 1994, the
Company, along with other PRPs, became a party to a Cost Sharing, Joint Defense
and Confidentiality Agreement, effective October 20, 1993. The Company believes
its share of costs in connection with the cleanup of the GI site will be
approximately $35,000 to $70,000 and will not have a material effect on its
financial position, cash flows or results of operations.
 
KANSAS AD VALOREM TAX  The Natural Gas Policy Act of 1978 (NGPA) allows a
"severance, production or similar" tax to be included as an add-on, over and
above the maximum lawful price for natural gas. Based on the Federal Energy
Regulatory Commission (FERC) ruling that the Kansas ad valorem tax was such a
tax, the Company collected the Kansas ad valorem tax in addition to the
otherwise maximum lawful price. FERC's ruling was appealed to the United States
Court of Appeals for the District of Columbia (D.C. Circuit), which held in June
1988 that FERC failed to provide a reasoned basis for its findings and remanded
the case to FERC for further consideration.
     On December 1, 1993, FERC issued an order reversing its prior ruling, but
limiting the effect of its decision to Kansas ad valorem taxes for sales made on
or after June 28, 1988. FERC clarified the effective date of its decision by an
order dated May 19, 1994. The clarification provided that the June 28, 1988
effective date applies to tax bills rendered after that date, not sales made on
or after that date. Based on Anadarko's interpretation of FERC's orders,
$700,000 (pre-tax) was charged against income in 1994, in addition to $130,000
(pre-tax) charged against income in 1993. Numerous parties filed appeals of
FERC's action in the D.C. Circuit. Anadarko, together with other natural gas
producers, challenged FERC's orders on two grounds: (1) that the Kansas ad
valorem tax, properly understood, does qualify for reimbursement under the NGPA;
and (2) FERC's ruling should, in any event, have been applied prospectively.
Other parties separately challenged FERC's orders on the grounds that FERC's
ruling should have been applied retroactively to December 1, 1978, the date of
the enactment of the NGPA and producers should have been required to pay refunds
accordingly.
     The D.C. Circuit issued its decision on August 2, 1996 which holds that
producers must make refunds of all Kansas ad valorem taxes collected with
respect to production since October 1983. Petitions for rehearing were denied
November 6, 1996. The Company, along with other gas producing companies,
subsequently filed a petition for writ of certiorari with the United States
Supreme Court seeking to limit the scope of the potential refunds to tax bills
rendered on or after June 28, 1988 (the effective date originally selected by
FERC). The petition has not been acted on. Williams Natural Gas Company has
filed a cross-petition for certiorari seeking to impose refund liability back to
December 1, 1978. The Company and other interested parties will oppose this
cross-petition. If Supreme Court review of the decision is unsuccessful, the
pursuit of other judicial and regulatory relief from the application of this
decision to the Company will be considered. The Company is unable at this time
to predict the final outcome of this matter. If, however, the August 2, 1996
decision is not reversed or modified by judicial review and if Anadarko is
unable to limit application of the decision to the Company, Anadarko estimates
the maximum amount of principal and interest at issue (assuming that the October
1983 effective date remains in effect) is approximately $37 million (pre-tax) as
of December 31, 1996.

RESULTS OF OPERATIONS FOR PRODUCING ACTIVITIES
 
     The following schedule includes only the revenues from the production and
sale of gas, oil, condensate and NGLs. Results of operations from oil and gas
marketing and gas gathering are excluded. The income tax expense is calculated
by applying the current statutory tax rates to the revenues after deducting
costs, which include depreciation, depletion and amortization (DD&A) allowances,
after giving effect to permanent differences. The results of operations exclude
general office overhead and interest expense attributable to oil and gas
production.

OIL AND GAS RESERVES
 
     The following table shows estimates prepared by the Company's engineers of
proved reserves and proved developed reserves, net of royalty interests, of
natural gas, crude oil, condensate and NGLs owned at year-end and changes in
proved reserves during the last three years. Volumes for natural gas are in
billions of cubic feet (Bcf) at a pressure base of 14.73 pounds per square inch
and volumes for oil, condensate and NGLs are in millions of barrels (MMBbls).
Total volumes are in millions of energy equivalent barrels (MMEEBs). For this
computation, one barrel is the equivalent of six thousand cubic feet. NGLs are
included with oil and condensate reserves and the associated shrinkage has been
deducted from the gas reserves. Other international reserve activity shown in
the following table includes 1994 activity for Canada and 1996 activity for
Indonesia.
     Algerian reserves are shown in accordance with the PSA. The reserves
include estimated quantities allocated to Anadarko for recovery of costs and
Algerian taxes and Anadarko's net equity share after recovery of such costs.
     Anadarko's reserves increased in 1996 primarily from exploration and
development drilling and improved recovery. At year-end 1996, the Company had
124.3 MMBbls of proved reserves in Algeria, including 31.8 MMBbls which were
added during 1996. Anadarko's reserves also increased in 1996 due to higher
natural gas and crude oil prices at year-end 1996 compared to year-end 1995.
     The Company's reserves increased in 1995 primarily due to exploration and
development drilling and improved recovery. At year-end 1995, Anadarko had 92.5
MMBbls of oil reserves in Algeria, including 48.5 MMBbls which were added during
1995. Anadarko's reserves also increased in 1995 due to higher natural gas and
crude oil prices at year-end 1995 compared to year-end 1994.
     The Company's reserves increased in 1994 primarily due to exploration and
development drilling and improved recovery. During 1994, Anadarko added 44
MMBbls of oil reserves in Algeria, based on successful exploration drilling,
preliminary development studies and the contractual rights granted under the
PSA.
     The Company emphasizes that the volumes of reserves shown below are
estimates which, by their nature, are subject to revision. The estimates are
made using all available geological and reservoir data as well as production
performance data. These estimates are reviewed annually and revised, either
upward or downward, as warranted by additional performance data.

DISCOUNTED FUTURE NET CASH FLOWS
 
     Estimates of future net cash flows from proved reserves of gas, oil,
condensate and NGLs were made in accordance with SFAS No. 69, "Disclosures about
Oil and Gas Producing Activities". The amounts were prepared by the Company's
engineers and are shown in the following table. The estimates are based on
prices at year-end. Natural gas prices have decreased by about 25 percent as of
February 1997. Oil prices have remained relatively stable through February 1997.
     Gas prices are escalated only for fixed and determinable amounts under
provisions in some contracts. Estimated future cash inflows are reduced by
estimated future development and production costs based on year-end cost levels,
assuming continuation of existing economic conditions, and by estimated future
income tax expense. Income tax expense, both U.S. and foreign, is calculated by
applying the existing statutory tax rates, including any known future changes,
to the pretax net cash flows giving effect to any permanent differences and
reduced by the applicable tax basis. The effect of tax credits are considered in
determining the income tax expense.
     At December 31, 1996, the present value (discounted at ten percent) of
future net revenues from Anadarko's proved reserves was $5.27 billion, before
income taxes, and $3.4 billion, after income taxes, (stated in accordance with
the regulations of the Securities Exchange Commission and the Financial
Accounting Standards Board). The after income taxes increase of 96 percent in
1996 compared to 1995 is primarily due to the significantly higher natural gas
and crude oil prices at year-end 1996 as well as additions of proved reserves
related to successful drilling in Algeria and Alaska.
     The present value of future net revenues does not purport to be an estimate
of the fair market value of Anadarko's proved reserves. An estimate of fair
value would also take into account, among other things, anticipated changes in
future prices and costs, the expected recovery of reserves in excess of proved
reserves and a discount factor more representative of the time value of money
and the risks inherent in producing oil and gas. Significant changes in
estimated reserve volumes or commodity prices could have a material effect on
the Company's consolidated financial statements.

                (ii) no event has occurred and is continuing, or would result

                (i) the Company is duly incorporated, validly existing and in
           good standing under the laws of the State of Delaware and is
           qualified to do business as a foreign corporation and is in good
           standing in the States of Colorado, Kansas, Louisiana, Montana,
           Nevada, New Mexico, Oklahoma, Texas and Wyoming;

                                        2
<PAGE>   3
 
                (iii) this Amendment, assuming due authorization, execution and
           delivery hereof by the Banks and the Agent, constitutes a valid and
           binding agreement of the Company, enforceable in accordance with its
           terms, except as (x) the enforceability thereof may be limited by
           bankruptcy, insolvency or similar laws affecting creditors' rights
           generally and (y) rights of acceleration and the availability of
           equitable remedies may be limited by equitable principles of general
           applicability;
 
                (iv) the execution, delivery and performance by the Company of
           this Amendment will not (x) conflict with the restated certificate of
           incorporation or by-laws of the Company, each as in effect on the
           date of such opinion, (y) contravene any applicable provision of any
           applicable law or applicable order or (z) conflict with any provision
           of any indenture, loan agreement or other similar agreement or
           instrument known to such counsel (having made due inquiry with
           respect thereto) binding on the Company or affecting its property;
 
                (v) no authorization, consent or approval of any governmental
           body or agency of the State of Texas or the United States of America
           which has not been obtained is required in connection with the
           execution, delivery and performance by the Company of this Amendment;
           and
 
                (vi) to the knowledge of such counsel (having made due inquiry
           with respect thereto), there is no proceeding pending or threatened
           before any court or administrative agency which, in the opinion of
           such counsel, will result in a final determination which would have
           the effect of preventing the Company from carrying on its business or
           from meeting its current and anticipated obligations on a timely
           basis.
 
             In rendering such opinion, the General Counsel of the Company shall
        opine only as to matters governed by the Federal laws of the United
        States of America, the laws of the State of Texas and the General
        Corporation Law of the State of Delaware and such counsel may state that
        he has relied on certificates of state officials as to qualification to
        do business and good standing certificates of officers of the Company
        and other sources believed by him to be responsible; and
 
             (c) Duly executed counterparts hereof signed by the Company, the
        Agent and each of the Banks (or, in the case of any party as to which an
        executed counterpart shall not have been received, the Agent shall have
        received telegraphic, telex or other written confirmation from such
        party of execution of a counterpart hereof by such party).
 
          4. Except as amended hereby, the Agreement shall continue in full
     force and effect.
 
          5. This Amendment shall be governed by, and construed in accordance
     with, the laws of the State of New York.
 
          6. This Amendment may be signed in any number of counterparts, each of
     which shall be an original, with the same effect as if the signatures
     thereto and hereto were upon the same instrument.
 
     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
executed by their respective officers thereunto duly authorized as of the day
and year first above written.

</TABLE>
 
     For purposes of this Schedule, the following terms have the following
meanings:
 
        "Level" refers to the determination of which of Level I, Level II, Level
     III, Level IV or Level V exists at any date. The higher rating of S&P or
     Moodys will determine the Level to be used.
 
          "Level I" exists at any date if, at such date, the Company's long-term
     debt is rated A- or higher by S&P or A3 or higher by Moodys.
 
          "Level II" exists at any date if, at such date, the Company's
     long-term debt is rated BBB+ by S&P or Baa1 by Moodys.
 
          "Level III" exists at any date if, at such date, the Company's
     long-term debt is rated BBB by S&P or Baa2 by Moodys.
 
          "Level IV" exists at any date if, at such date, the Company's
     long-term debt is rated BBB- by S&P or Baa3 by Moodys.
 
          "Level V" exists at any date if, at such date, the Company's long-term
     debt is rated below BBB- by S&P or below Baa3 by Moodys.
 
     In the event a rating is not available from either Moodys or S&P, such
rating agency will be deemed to have assigned its lowest rating.
 
     The credit ratings to be utilized for purposes of this Schedule are those
assigned to the senior unsecured long-term debt securities of the Company 
without third-party credit enhancement, and any rating assigned to any other 
debt securities of the Company shall be disregarded. The rating in effect at 
any date is that in effect at the close of business on such date.

                (ii) this Amendment has been duly authorized, executed and
           delivered by the Company;
 
                (iii) this Amendment, assuming due authorization, execution and

           respect thereto) binding on the Company or affecting its property;
 
                (v) no authorization, consent or approval of any governmental
           body or agency of the State of Texas or the United States of America

        and other sources believed by him to be responsible; and
 
             (c) Duly executed counterparts hereof signed by the Company, the
        Agent and each of the Banks (or, in the case of any party as to which an
        executed counterpart shall not have been received, the Agent shall have
        received telegraphic, telex or other written confirmation from such
        party of execution of a counterpart hereof by such party).
 
          4. Except as amended hereby, the Agreement shall continue in full
     force and effect.
 
          5. This Amendment shall be governed by, and construed in accordance
     with, the laws of the State of New York.
 
          6. This Amendment may be signed in any number of counterparts, each of
     which shall be an original, with the same effect as if the signatures
     thereto and hereto were upon the same instrument.

     For purposes of this Schedule, the following terms have the following
meanings:
 
        "Level" refers to the determination of which of Level I, Level II, Level
     III, Level IV or Level V exists at any date. The higher rating of S&P or
     Moodys will determine the Level to be used.
 
          "Level I" exists at any date if, at such date, the Company's long-term
     debt is rated A- or higher by S&P or A3 or higher by Moodys.
 
          "Level II" exists at any date if, at such date, the Company's
     long-term debt is rated BBB+ S&P or Baa1 by Moodys.
 
          "Level III" exists at any date if, at such date, the Company's
     long-term debt is rated BBB by S&P or Baa2 by Moodys.
 
          "Level IV" exists at any date if, at such date, the Company's
     long-term debt is rated BBB- by S&P or Baa3 by Moodys.
 
          "Level V" exists at any date if, at such date, the Company's long-term
     debt is rated below BBB- by S&P or below Baa3 by Moodys.
 
     In the event a rating is not available from either Moodys or S&P, such
rating agency will be deemed to have assigned its lowest rating.
 
     The credit ratings to be utilized for purposes of this Schedule are those
assigned to the senior unsecured long-term debt securities of the Company
without third-party credit enhancement, and any rating assigned to any other
debt securities of the Company shall be disregarded. The rating in effect at any
date is that in effect at the close of business on such date.

     The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. 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. Certain amounts for
prior years have been restated to conform to the current presentation.
 
     During the five years ended December 31, 1996, there were no shares of
preferred stock outstanding. Accordingly, the ratio of earnings to combined
fixed charges and preferred stock dividends for each of the five years is the
same as the ratio of earnings to fixed charges.

1996

1996 was a record year for Anadarko. The Company benefited from strong commodity
prices for gas, oil and natural gas liquids (NGLs), posting record revenues,
cash flow and net income. However, our successes were much more than monetary.

         Record levels of activity were achieved in nearly all of the Company's
core operating areas. Significant capital investments were made in the areas of
southwest Kansas, the Permian Basin of west Texas, the Gulf of Mexico and
Alaska. Using the drill bit, Anadarko again replaced its annual production
volumes with proven reserves of oil and gas. These reserves were found at costs
well below the most recent available industry averages.

         Overseas, our development work in Algeria moved us closer to first
production. With highly-prospective acreage remaining in Algeria, Anadarko
continued to explore, drilling three discoveries. The Company signed two new
international ventures in 1996 to generate future opportunity and continued
growth and also divested its interests in Indonesia.

         With the strongest portfolio of exploitation and development drilling
projects in Company history, Anadarko announced that by 2000 production should
double from current levels. This section details the Company's 1996 work
program.

ALGERIA

Anadarko's 1996 work program in Algeria's Sahara Desert balanced delineation of
known fields with continued exploration. The Company successfully drilled four
delineation wells and three wildcat discovery wells. With results from the
Algeria drilling program, the Company's estimates of net, proved reserves were
raised to 124.3 million barrels (MMBbls) of crude oil and condensate, an
increase of 34 percent over 1995. Algeria represents about 20 percent of the
Company's total proved reserves.

         The Algerian work program accounted for the largest portion of the
Company's international budget. Capital spending for 1996 totaled $85 million
and Anadarko plans to invest $191 million in Algeria in 1997.

Developing Known Discoveries

In 1996, SONATRACH received a Provisional Exploitation Authorization (PEA) from
the Algerian government for wells in the Hassi Berkine (HBN) and Hassi Berkine
South (HBNS) Fields. This gave Anadarko approval to begin development operations
toward first production.

         In September 1996, Anadarko and partners signed a $177-million
Engineering, Procurement and Construction (EPC) contract with Brown & Root
Condor for Stage I production facilities at the HBNS Field. Anadarko and its
partners are working toward first production of 60,000 barrels of oil per day
(BOPD) (gross) in early 1998. Construction is underway which includes oil and
gas processing facilities and separators, compression equipment to reinject
natural gas, oil storage tanks with a capacity of
<PAGE>   3
180,000 barrels, and office, accommodation and maintenance facilities. The
Company plans to spend approximately $120 million on development activities in
Algeria in 1997.

         HBNS Field ~ The HBNS Field was discovered in 1995 and three
delineation wells have been drilled in the Field to date. Three of the wells
tested at unstimulated flow rates ranging from 14,500 - 17,000 BOPD.  A
comprehensive development plan is being prepared that calls for drilling about
53 wells in the 30,000-acre HBNS Field. Development drilling will begin in 1997.
Additional production facilities at the HBNS Field are planned to increase
production volumes in subsequent stages of development.

         Initial production from the HBNS Field will move through a new 30-inch
pipeline being constructed by SONATRACH. The pipeline, expected to be completed
in late 1997, runs just south of the HBNS Field west to the Nezla area and north
past the giant Hassi Messaoud Field. Production will then be transported to
multiple export terminals on the Mediterranean Coast. Markets for this Saharan
Blend crude oil are now being identified by Anadarko's marketing department.

         HBN Field ~ Development planning is underway at the HBN Field, located
on Block 404 just north of the HBNS Field. Since the HBN Field was discovered
in 1994 (the HBN-1 well tested 4,900 BOPD), the partners have drilled one
successful delineation well - the HBN-2 well which tested 13,750 BOPD. A third
delineation well - the HBN-4  - was drilled three miles southwest of the HBN-1
discovery well. Although it was a dry hole, the well encountered thick,
reservoir quality sands and established the oil/water contact. The well was
cased and will be used as a future injection well.

         In March 1996, the Italian company, Agip, announced a discovery called
the Hassi Berkine North No. 1 (HBNN-1), located just north of Block 404, which
demonstrated the extension of the HBN Field onto Agip's Block 403. The HBNN-1 
well tested 14,818 BOPD. In December 1996, results from the HBNN-2 well were
announced, flowing 12,000 BOPD. Anadarko and partners are working with Agip on
the Commerciality Report and a joint development plan for the Field. The
companies plan to file the Commerciality Report for the HBN Field in 1997. An
Exploitation License could be granted in late 1997 with first production
projected for late 1999.

         BKE Field ~ Anadarko's largest Algerian Field discovered to date is
the Berkine East (BKE) Field, located on Block 404. Discovered in 1994, the BKE
Field stretches about 25 kilometers from north to south and is located on both
Anadarko and Cepsa (a Spanish oil company operating on Block 406) acreage. Since
1994, Anadarko and partners have drilled two successful delineation wells in the
BKE Field; two of the wells tested at unstimulated rates above 15,000 BOPD.
Cepsa has drilled three delineation wells in the Field.

         During 1996, Anadarko and partners drilled the BKE-4 well, the second
delineation well in the Field. The well was drilled about five kilometers from
the BKE-1 discovery well and logged 70 feet of net pay, confirming the 
significant westward extension of the Field on Anadarko's acreage. The well was
not tested and was cased and suspended for future production.

         Anadarko and partners are currently preparing a joint development plan
and a Commerciality Report for the BKE Field with Cepsa. The Commerciality
Report should be submitted to SONATRACH in 1997. Following receipt of  an
Exploitation License, initial production is expected in late 1999.
<PAGE>   4
    EME Field ~ Delineation drilling at the El Merk East (EME) Field, located
on Block 208, was conducted in 1996. The EME Field is the fourth oil field
discovered by the partners since 1993. The EME-2 delineation well, located
about 2.4 kilometers east of the EME-1 discovery well, tested three zones with
combined flow rates in excess of 18,000 barrels of oil and condensate per day
and 66 MMcf/d of gas. The EME Field area is structurally complex and has
multiple productive zones of oil, gas and condensate. The commercial potential
of this field is under evaluation.

Continued Exploration

Significant exploration potential remains on the partners' acreage. In 1997,
Anadarko plans a two-rig drilling program to drill up to 10 exploration targets.
The Company plans to invest about $50 million on exploration in Algeria in 1997.

         Four exploration wells were drilled in 1996, of which three were
discoveries.

         BKNE-1 ~ The Berkine North East No. 1 discovery well was drilled 18
kilometers west of the BKE Field and logged 14 feet of net oil pay. The well
was not tested and was  cased and suspended. Additional evaluation is underway
to determine the potential of this discovery. The new SONATRACH 30-inch
pipeline will come very close to the BKNE-1 discovery.

         EKT-1 ~ The El Kheit Et Tessekha No. 1 (EKT-1) discovery well is
located in the north- west corner of Block 208. The well found 144 feet of net
hydrocarbon pay sands and flowed at an unstimulated rate of 13,568 BOPD and 8.8
MMcf/d of gas. Partners will evaluate the results of the EKT-1 well and expect
further delineation drilling to better evaluate this significant discovery.

         EMC-1 ~ The El Merk Central No. 1 (EMC-1) well, located on Block 208,
was completed in late 1996. The well flowed 1,278 barrels of condensate per day
(BCPD) and 10.2 MMcf/d of  gas. The EMC-1 well successfully tested a new fault
block adjacent to the EME Field and is the fourth exploration success on Block
208 since 1993. EMC-1 is located 1.5 kilometers west of the EME Field and six
kilometers southwest of EMK-1.

         TAKS-1 ~ The Takouazet South No. 1 (TAKS-1) was drilled on the 
partners' southernmost acreage - Block 245, a previously undrilled area. The
well discovered no commercial hydrocarbons and was plugged and abandoned.

         Anadarko's interest in the Algerian PSA for Blocks 208, 211, 245 and
404 is 50 percent before participation at the exploitation stage by SONATRACH.
The Company has two other partners, LASMO and Maersk.

         In addition to Anadarko's original exploration area, the Company
acquired a minority interest in a PSA for two additional blocks covering about
1.2 million acres in 1994. The Blocks, 401 and 402, are located east of Block
404 and are operated by BHP Petroleum (Algerie) Inc. In 1996, BHP and Anadarko
shot 1,900 kilometers of high-quality seismic data and are currently evaluating
exploration drilling plans for 1997. In December 1996, Agip announced a
discovery - the BRSE No. 1 - located less than one mile from the partners' lease
boundary. The BRSE No. 1 well tested about 13,000 BOPD. Anadarko owns a
27.5-percent interest in the two blocks.

ALASKA

Anadarko has been exploring on Alaska's North Slope with partner ARCO Alaska,
Inc. since 1992. Today, Anadarko is active in two regions in Alaska: the
Colville area on the North Slope and the Cook Inlet.

         Anadarko invested about $14 million in its Alaska operations in 1996
and plans to spend about $17 million in 1997. The budgeted dollars are equally
split between development of the new Alpine Field and continued geological and 
geophysical studies in the Cook Inlet.

The Alpine Field

In October 1996, Anadarko and partners announced plans to develop the Alpine
Field, a major oil field on Alaska's North Slope. Located about 50 miles west
of Prudhoe Bay, the Alpine Field holds proven and potential oil reserves of
250-300 million barrels (gross). This Field is the largest domestic onshore
discovery announced in the last decade and the fifth largest field in Alaska.

         Development work is underway in the Field with first production of
30,000 BOPD (gross) expected in 2000.  Production should double to 60,000 BOPD
(gross) in 2001. The partners are planning a 100-150 well program with an
estimated development cost of $700-$800 million (gross). In 1997, partners plan
to complete interpretation of a 150 square-mile 3-D seismic survey conducted in
early 1996.

         Technological advancements and an appreciation for the environment
allow oil and gas operations and wildlife to co-exist in pristine areas like
Alaska. Minimizing environmental impact is a key factor in development of the
Alpine Field.

         Directional drilling will be conducted from two well pads, totaling 85
acres. Construction of the drilling pads is expected to commence in 1997 with
development drilling estimated to begin in early 1999. A 16-20 inch, 34 mile
pipeline will be constructed to connect the production facility to the Trans
Alaska Pipeline System terminus in the Kuparuk River Field. A one-mile section
of the pipeline will be  tunneled 110 feet below the surface of the Colville
River, eliminating the need for costly roads and bridges. Pipeline construction
is scheduled to begin in late 1997.

         Equipment and personnel will be moved by small aircraft, helicopters 
and, during the winter months, surface vehicles over an ice road. Through 
innovative solutions like these, the partners plan to reduce development costs 
for the Alpine Field by about 30 percent compared to other North Slope Fields.

         To secure additional acreage, Anadarko and partners invested about $2
million for five tracts totaling 5,900 acres near the  Alpine Field in State
Lease Sale 86A held in October 1996. A complete geological and geophysical
evaluation of this acreage was conducted in 1996.
<PAGE>   6
         Partners in the Alpine Field include ARCO Alaska, Inc. (operator),
56-percent working interest; Anadarko, 22-percent  working interest; and, Union
Texas Petroleum Alaska Corp., 22-percent working interest.

The Cook Inlet

Anadarko's long-term interest in Alaska was further demonstrated when the
Company signed a strategic alliance with ARCO Alaska in 1996 to explore the
Upper Cook Inlet on the state's southern coast. Anadarko will combine its
experience and proven track record in exploration with ARCO's experience in
Alaska.

         The two-year agreement gives Anadarko access to ARCO Alaska's 127,000 
lease acres in the area. Anadarko will serve as operator and will supervise an 
Anchorage-based team of geoscientists. In December 1996, Anadarko and ARCO 
Alaska purchased 10 lease blocks for $832,000 covering 39,000 acres on the west 
side of the  Cook Inlet and on the Kenai Peninsula.

         During 1996, Anadarko reviewed existing seismic data in the Cook Inlet
region to identify areas for a new seismic acquisition program. Anadarko 
completed a 73-mile seismic shoot in early 1997 and is planning to complete
another 74-mile seismic shoot in the first half of 1997. The Company expects to
develop a list of exploratory prospects by 1998. Anadarko plans to invest about
$7 million (net) on its Cook Inlet technical evaluations in 1997.

         Anadarko (operator) and ARCO Alaska each have a 50-percent working
interest in the Cook Inlet alliance.

The Beaufort Sea

In September 1996, Anadarko and partner ARCO Alaska acquired six lease blocks
totaling about 34,000 acres in the Beaufort Sea, off the North Slope of Alaska.
The companies are reviewing existing seismic data and plan to acquire new
seismic information in late 1997. ARCO Alaska (operator) owns a 78-percent
working interest in the blocks. Anadarko owns a 22-percent working interest.

         Alaska is one of the country's last domestic frontiers for oil and gas 
exploration. Anadarko plans to look at other opportunities within the state and 
will continue to allocate future exploration and development efforts to this 
new core area.



GULF OF MEXICO

Anadarko's Gulf of Mexico activities in 1996 were highlighted by installation
of and first production from the Mahogany platform and by two additional
sub-salt discoveries. Anadarko invested about $103 million on its Gulf of
Mexico operations in 1996.

         At year-end 1996, about 13 percent of Anadarko's proved energy
reserves were located in the Gulf of Mexico. Anadarko's Gulf of Mexico
production in 1996 averaged 119 MMcf/d of gas and 2,000 barrels of oil and
condensate per day.
<PAGE>   7
         The Company plans to maintain a balanced program of exploration and
development in both conventional and sub-salt plays. Anadarko plans to spend
about $87 million in 1997 for Gulf of Mexico exploration and development.

The Mahogany Field

The industry's focus on the Gulf of Mexico's sub-salt play began in September
1993 when Anadarko and its partners made the Mahogany discovery, located at 
Ship Shoal South Addition 349/359 about 80 miles offshore Louisiana. After
drilling three successful delineation wells, the Mahogany Field  was declared
commercial by the partners in April 1995. The platform was installed in August
1996 and first production began in late December 1996.

         At the time this report was released for printing, production tests
from two wells at the Mahogany platform totaled approximately 14,000 BOPD and
14 MMcf/d of gas (gross). The partners are in the process of completing the
remaining two wells drilled to date and expect to bring them on-line in 1997.
Production from these four wells is estimated to peak in 1997 at about 22,000
BOPD and 30 MMcf/d of gas. Additional wells drilled from the platform could
increase production. This platform can also be used to produce discoveries from 
the partners' neighboring blocks.

         Phillips Petroleum Company (operator) and Anadarko each own a
37.5-percent working interest in the Mahogany Field. Amoco Production Company
owns a 25- percent working interest.

Sub-Salt Success

Anadarko continued its sub-salt play success in 1996 by announcing two
discoveries: Agate and Monazite. The Company also drilled three dry holes in
1996. Anadarko  has one of the industry's most extensive portfolios of sub-salt
prospects with 17 prospects on 32 lease blocks.

         Agate ~ Anadarko and partners' third sub-salt discovery to date was
Agate, located at Ship Shoal 361, about 72 miles offshore Louisiana. Two
separate zones in a single sand formation were tested at Agate, with the well
flowing 4,126 BOPD and 24.1 MMcf/d of gas. The well was drilled to a total
depth of 16,163 feet and encountered a gross hydrocarbon interval of 105 feet.
The discovery is located in about 400 feet of water.

         Agate is located about six miles west of the Mahogany Field. The
partners are analyzing the possibility of installing sub-sea completion
facilities at Agate, tying production  to the Mahogany platform. Anadarko and
Phillips (operator) each own a 50-percent working interest in the Agate Field.

         Monazite ~ In November 1996, Anadarko announced the Monazite discovery,
located at Vermilion South Addition 375. Well logs, core analyses and production
tests confirmed multiple hydrocarbon bearing sands.

         Production tests were attempted over a one-month period on separate
pay intervals. Although all intervals flowed oil, the information was
inconclusive. Poor wellbore conditions resulted in the well being plugged and
abandoned. Anadarko and
<PAGE>   8
partners are reviewing existing seismic data and future appraisal drilling is
needed to confirm commerciality of the Monazite discovery. The Company is
planning a delineation well at Monazite during 1997. Anadarko (operator),
Broken Hill Proprietary (BHP) and Phillips each hold a 33.33-percent working
interest in the Monazite discovery.

Sub-Salt in 1997

Anadarko and partners have drilled a total of eight exploratory sub-salt wells
with four discoveries (Mahogany, Teak, Agate, Monazite). The Company is very
encouraged by the results in this play to date and has five prospects in the
final stages of exploration preparation. Anadarko has budgeted about $40
million (net) for sub-salt exploration in 1997.

         In January 1997, Anadarko and partners spudded the Lion No. 1
prospect, located at South Timbalier 299, about 60 miles offshore Louisiana.
BHP (operator), Anadarko and Phillips each own a 33.33-percent working interest
in the prospect.

         During 1997, Anadarko will continue to evaluate its prospect inventory
and make determinations on drilling order. In 1996, more than $9 million was
spent on new seismic acquisition and processing to help "firm-up" drilling
locations.

         Including other operators, nine sub-salt wells were drilled in the Gulf
of Mexico in 1996 and seven wells were drilling at the time of publication. 
Technological advancements in seismic acquisition, processing and structural 
modeling have yielded better solutions to sub-salt challenges. While the 
industry is still learning, the success of Anadarko and others proves the 
potential of the sub-salt play.

Conventional Operations

Conventional operations in the Gulf of Mexico in 1996 focused on drilling and
recompletions, or enhancing the production capabilities of existing wells. The
Company participated in the completion of three new wells in 1996 and 10
additional wells were recompleted. Production from these wells added 52 MMcf/d
of gas and 2,760 BOPD.

         In 1996, Anadarko drilled three conventional exploration wells - all
dry holes. Two additional exploration wells began drilling in late 1996.

         In 1997, Anadarko plans to drill three conventional exploration wells
in the Gulf of Mexico. Eight development wells are also planned in 1997. 
Anadarko's recompletion program will continue in 1997.

Going Deep

Encouraged by the industry's success in the deepwater of the Gulf of Mexico,
Anadarko and partners in September 1996 acquired 12 lease blocks in Offshore
Lease Sale No. 161. The blocks have water depths ranging from 2,700-5,700 feet.
The Company operates 10 of the blocks.

         Anadarko selected its deepwater blocks by interpreting available 2-D
and 3-D seismic data. The Company plans to acquire 3-D data on seven of the
blocks in 1997. One exploratory prospect could be drilled in late 1997.
<PAGE>   9
THE HUGOTON EMBAYMENT

In the Hugoton Embayment, located in southwest Kansas and the Oklahoma
Panhandle, the Company operates about 2,000 wells on about 500,000 lease acres.
During 1996, Anadarko drilled 72 development wells and recompleted 27 wells.
Activities are concentrated on two major work programs - the shallow, low
pressure gas formations and the deep oil and gas zones found beneath the
shallow production.

         The Company's 1996 capital spending in the Hugoton Embayment was $30
million, excluding acquisitions. Record activity is expected in 1997, with 130
development wells and 40 recompletions budgeted. Capital spending for 1997 is
estimated at about $50 million, an increase of 66 percent over 1996.

         Over the last four years, Anadarko has invested about $77 million in
its Hugoton Embayment operations, drilling nearly 300 development wells and
recompleting about 70 wells. Through this program, the Company has added 31.2
MMEEBs of proved reserves.

         Net production in 1996 from the Hugoton Embayment was 85.8 billion
cubic feet (Bcf) of gas and 1.6 MMBbls of oil. This area accounted for 42
percent of the Company's total production volumes in 1996. Gas production is
predicted to rise in 1997-98.


Developing the Shallow Formations

The shallow gas formations (2,000-3,500 feet) are contained in four fields: the
Hugoton, Panoma Council Grove and Greenwood Fields, located in southwest
Kansas, and the Guymon-Hugoton Field, located in the Oklahoma Panhandle. The
Company is still developing reserves in the shallow Hugoton Field even though
it was discovered in 1922.

         During 1996, Anadarko invested about $5 million in shallow gas
drilling in the area. The Company drilled and completed 17 wells (10 infill
wells and seven replacement wells), adding production of 4.5 MMcf/d of gas. At
year-end 1996, an additional 11 wells were drilled and are in various stages of
completion. In 1997, the Company has budgeted $7 million to drill 30 wells.

         Another major component of the Company's program is workovers - or
improving production from existing wells. At year-end 1996, 17 workover rigs
were operating in the Hugoton Embayment. Anadarko worked over about 100 wells
in 1996 and plans to workover about 150 wells in 1997. Better completions,
utilizing improved fracture-stimulation technology, should help increase
production volumes in 1997.

Exploiting Deep Horizons

Anadarko is exploring and developing the deeper productive horizons
(5,000-6,000 feet) below the shallow gas fields with success.

         During 1996 in the deeper formations, the Company drilled 55 wells and
recompleted 27 wells, representing a capital expenditure of about $17 million.
Net production in 1996 from the deeper horizons in the area averaged 53 MMcf/d
of gas and
<PAGE>   10
4,600 BOPD. This represents about 13 percent of the Company's total production
volumes. Anadarko is now the largest oil producer in southwest Kansas.

         In 1997, 100 development wells and 40 recompletions are planned in
deeper zones with an estimated expenditure of about $29 million. This drilling
program is largely based on 3-D seismic. In 1996, the Company spent $8 million
to acquire 339 square-miles of 3-D seismic data in the area. The results of
these surveys were used to identify drilling locations in the Chester and
Morrow producing trends. In 1997, the Company plans to acquire an additional
200 square-miles of 3-D seismic over other prospective areas.

         Property acquisitions have helped solidify the Company's acreage
positions in the area. The largest acquisition by the Company in this area was
from Mesa Operating Limited Partnership in 1993. Anadarko acquired the "deep"
rights to oil and gas properties encompassing 21,000 net acres. Anadarko has
drilled 45 development wells on this acreage since the 1993 acquisition, with
production increasing from 500 BOPD and 400 thousand cubic feet per day (Mcf/d)
of gas in 1993 to a peak of 2,000 BOPD and 5,000 Mcf/d of gas in 1996. The
Company also acquired a 6.5-percent override interest in an additional 188,000
acres which are under a pre-existing farm-out arrangement with another company
until 1999 when the undeveloped portion of the acreage will revert to Anadarko.

         In March 1996, Anadarko acquired about 24,000 net acres in the
Oklahoma panhandle (Cimarron and Texas Counties) from another operator for $2.9
million. The Company also farmed-in an additional 31,000 net acres. A 3-D
survey of the area is planned and the Company anticipates drilling 11
development wells on the acreage in 1997.

Gathering Operations

In March 1996, Anadarko closed the acquisition of Panhandle Eastern Pipe Line
Company's (PEPL) West End gas gathering assets in the Hugoton Field area. This
was the second of two recent  acquisitions from PanEnergy Corp. When combined,
the two acquisitions triple Anadarko's gathering capacity to 480 MMcf/d of gas.
The PEPL acquisition includes 1,150 miles of pipeline, 16 compressor stations
and serves nearly 1,000 Anadarko-operated wells and 200 third-party wells.
Anadarko took over operation of the Cimarron River System (CRS) in late 1994.
The purchase price for the two systems was about $35 million.

         During 1996, Anadarko invested $15 million for upgrades to the
Company's gas gathering system in southwest Kansas. Control of gathering assets
helps the Company maximize production and meet  changing market demands.

         Over the last three years, Anadarko has invested about $10 million
installing computerized well automation systems in southwest Kansas. The
system electronically tracks the producing status of about 1,500 Company-
operated wells in southwest Kansas and the Oklahoma and Texas panhandles. 
Anadarko spent $3 million in 1996 to install the automation system on wells 
connected to the PEPL and CRS systems.
<PAGE>   11
PERMIAN BASIN

An aggressive work program in the Permian Basin of west Texas during 1996
focused on development drilling, increased density drilling and waterflood
implementation. Drilling activity in 1996 reached record levels in the Permian
Basin. At year-end 1996, Permian Basin net production was about 9,500 BOPD, or
about half of the Company's total daily oil production.

         In 1996, Anadarko invested about $36 million in the area. The Company
drilled 182 wells (163 development wells and 19 injection wells) in the Permian
Basin in 1996 compared to 96 wells (73 development wells and 23 injection
wells) the previous year. Anadarko plans to drill more than 200 wells in the
Permian Basin in 1997, with planned capital expenditures of $46 million. At the
time this report was released for printing, 10 Company-operated rigs were
drilling in the Permian Basin.

         The most active area in 1996 was the TXL South Unit of Ector County,
Texas. Anadarko drilled and completed 55 infill wells in the Unit in 1996. As a
result of this infill drilling program, gross production has increased from
1,070 BOPD and 1.2 MMcf/d of gas in 1995 to a current rate of 3,200 BOPD and
5.9 MMcf/d of gas.

         The Company's working interest in the TXL South Unit has increased
from less than one percent to 65 percent through a series of acquisitions and
trades over the past four years. Anadarko plans to spend about $17 million in
the TXL South Unit in 1997 to drill 50 development wells and add pay in 20
existing wells. An additional 40 wells will be deepened to expose more pay
interval. Plans call for expanding waterflood operations over the next few 
years. Anadarko currently operates about 200 producing wells in the TXL South
Field on about 10,000 lease acres (gross).

         In the Sharon Ridge/Diamond M Fields in Scurry County, Texas, the
Company initiated secondary recovery operations in 1996 on approximately 1,500 
acres. A $13 million program is underway to drill 32 producing wells, 46 
injection wells and construct waterflood facilities. At year-end 1996, the
program was about 30 percent complete. Anadarko currently operates 300 
producing wells in these fields with average 1996 production of 1,500 BOPD.

GULF COAST

In the Gulf Coast regions of Mississippi, Texas and Louisiana, Anadarko is
active in several high-potential exploratory plays. Many of these areas remain
relatively under-explored with modern technology and the Company is introducing
new strategies in the search for hydrocarbons.

Smackover Play

In 1996, Anadarko participated in the largest 3-D seismic survey ever conducted
in Mississippi - a 202 square-mile area in the Smackover Play in Wayne County.
The survey provided data on several exploratory leads that the Company 
identified from existing 2-D data that was reprocessed in 1995. Potential
reservoirs in the Smackover Play are located on the flanks of large,
steeply-dipping salt structures.
<PAGE>   12
         In 1997, Anadarko plans to drill up to four exploratory wells. The
first prospect spudded in February 1997. Anadarko will continue to evaluate
the 3-D seismic results for the remainder of the 1997 drilling program.
Anadarko spent $2 million on its Smackover exploratory program in 1996 and plans
to invest about $11 million in 1997. Anadarko owns 20,000 (gross) lease acres in
Wayne and Jones Counties. The Company has a 50-percent working interest in this 
venture.

Wilcox Play

Anadarko is also evaluating exploration prospects in the Wilcox Play, located
primarily in Jim Hogg County,  Texas. The Company is currently working on a
leasing program in the area. During 1996, Anadarko conducted a 120 square-mile
3-D seismic survey. The seismic data was processed in late 1996 - early 1997
and the Company plans to drill an exploratory well  in mid-1997. Anadarko has a
33.33-percent working interest in the exploratory venture.

Yegua Trend

Development of the Yegua Trend along the Texas Gulf Coast has been ongoing
since 1991. In February 1996, Anadarko successfully completed the Doornbos No.
1 well, located in Jefferson County, Texas. The Doornbos No. 1 is currently
producing 6 MMcf/d of gas and 1,000 BCPD (gross). Anadarko owns a 50-percent
working interest in the well.

         In 1997, Anadarko plans to drill at least one well offsetting a 1996
discovery in the Nome Field area, near Beaumont, Texas. Prospects are being
evaluated and the Company plans to shoot a 3-D seismic survey in the Yegua
Trend in 1997. Anadarko has an average 50-percent working interest in
approximately 18,400 (gross) lease acres.



GOLDEN TREND

Stronger gas prices brought renewed activity to the Company's acreage in the
Golden Trend of central Oklahoma. In 1996, Anadarko drilled 15 successful wells
in Garvin and Grady Counties, Oklahoma. Production from the Golden Trend
averaged 18.3 MMcf/d of gas and 433 BOPD in 1996.

         Anadarko's 1997 budget includes about $15 million for Golden Trend
development drilling compared to an expenditure of $8 million in 1996. In 1997,
the Company plans to drill 31 wells on existing acreage.

         Anadarko owns interests in more than 250 wells in the area, of which
176 are Company-operated. The Company has about 20,600 undeveloped lease acres
(gross) in Garvin, Grady and McClain Counties.

1997 & BEYOND

The next millennium is fast approaching. As we enter this new era, our
continued success will derive from a foundation built over the last 38 years.
Our basic goals will not change and our unyielding attention to stockholder
value will go unaltered.

         But there will be few constants in the 21st century. Technology will
continue to evolve, changing the way our industry faces challenges and develops
solutions. Hydrocarbon exploration will move to remote areas of the world -
areas that were unimaginable 20 years ago. Anadarko is positioning itself to be
a leader in this new world.

         Our future is bright. Anadarko's proven domestic base - areas like
southwest Kansas, the Permian Basin and the Gulf of Mexico - will produce for
years at low operating costs and strong profitability. The Alpine Field on
Alaska's North Slope will come on-line in 2000 and new opportunities should
open within the state.

         Internationally, Algeria will lead Anadarko's growth in both reserves
and production volumes. Exploration continues and Anadarko has recently signed
three multi-phased international ventures - Eritrea, Jordan and Peru - and
continues to investigate dozens of other leads around the globe. Using proven
strategies, the best of technologies and experience, Anadarko will continue to
prosper.



ERITREA

The Red Sea off the coast of Eritrea, Africa's newest nation, was essentially
off limits for exploration for more than 30 years while Eritrea fought for its
independence from Ethiopia. Anadarko was the first energy company to sign a PSA
with the new government following liberation.

         Signed in 1995, the agreement gives Anadarko rights to explore a 6.7
million-acre area known as the Zula Block. Anadarko invested about $8 million
on its Eritrea work program in 1996 and plans to spend about $8 million in
1997. The Company is prepared to invest about $30 million over  the next
several years to prove exploration prospects.

         In early 1996, Anadarko completed a high-density aerial gravity and
magnetics survey to identify locations for the 4,500 kilometer seismic program
that began in November 1996. During 1997, the seismic data will be interpreted
and combined with 15,000 kilometers of existing seismic data. The Company hopes
to drill its first exploration well in Eritrea in late 1997 or early 1998.

         Anadarko is very encouraged by its early technical evaluations in
Eritrea. Much of the geology is similar to that of neighboring regions with
substantial oil and gas production. The Red Sea has salt structures and
Anadarko will apply its Gulf of Mexico experience to this exploratory effort.

         Anadarko owns a 100-percent interest in the Eritrea venture but may
take partners. The Company opened an office in Asmara, Eritrea, the capital
city, in early 1996.

JORDAN

Jordan was added to the Company's growing list of international ventures in
March 1996. Anadarko Jordan Company, a wholly-owned subsidiary, signed a PSA
with the Natural Resources Authority of the Hashemite Kingdom of Jordan.
Anadarko has the right to explore a 4.2 million acre area known as the Safawi
Block, located in northeast Jordan.

         Anadarko invested about $2 million on its Jordan efforts in 1996 and
has budgeted about $4 million for 1997. Anadarko has committed to spend at least
$5 million in the first two-and-one-half years of the exploration period. In
1996, the Company conducted a magnetotelluric survey of the area and reprocessed
more than 1,000 kilometers of existing seismic data. The information will be
used to determine specific locations for two stratigraphic test wells planned
for 1997. The test wells will analyze source rock and look for signs of a       
working petroleum system.

         Anadarko is operator of the Safawi Block. In 1997, a subsidiary of
Union Texas Petroleum Corporation joined Anadarko as a partner in Jordan with a
50-percent interest. Anadarko opened an office in Amman, Jordan, the capital
city, in early 1997.


PERU

In September 1996, Anadarko signed an exploration license agreement with
PERUPETRO S.A., the state company established in Peru. Anadarko Peru Company, a
wholly-owned subsidiary of Anadarko, has the right to explore a 2.56-million
acre area, known as Block 84, in the Ucayali region near the Brazilian border.

         Anadarko is now operating under Phase I of a five-phase agreement.
During the two-and-one-half year initial phase, the Company is committed to
spend about $5 million to acquire a minimum of 600 kilometers of seismic. The
Company invested about $2 million in Peru in 1996 and has budgeted about $2
million for exploration efforts in 1997.
         
         In the fourth quarter of 1996, Anadarko flew a 7,300 kilometer aerial
magnetic survey of Block 84 to help determine specific locations for a 700
kilometer seismic program that should begin in the second quarter of 1997. A
second 20,000 kilometer aerial magnetic survey is planned for late 1997.
Anadarko will also continue a geological and geophysical program in 1997 to
analyze surface gravity and chemistry. The seismic data will be analyzed in 1997
and used to develop possible exploration prospects in 1998.

         Block 84, located east of the Andes Mountains and about 450 miles 
northeast of the capital city of Lima, is sparsely populated. Anadarko conducted
an Environmental Assessment of the Block in late 1996 and will use the findings
to identify environmental issues prior to the seismic exploration program in
1997. The data will also be used to develop a comprehensive environmental
management plan. These documents should be submitted to the Peruvian government
in early 1997.

         Anadarko owns a 100-percent interest in Block 84 but may take
partners. The Company opened an office in Lima, Peru, the capital city, in
early 1997.

     All elections for directors shall be decided by a plurality of the votes
cast in respect thereof. If no voting direction is indicated on the proxy card,
the shares will be considered votes for the nominees. In accordance with
Delaware law, a stockholder entitled to vote for the election of directors can
withhold authority to vote for all nominees for directors or can withhold
authority to vote for certain nominees for director.
 
     Abstentions from voting with respect to proposals are treated as votes
against the particular proposal. If a broker indicates on a proxy that it does
not have discretionary authority as to certain shares to vote on a particular
proposal, those shares will not be considered as present and entitled to vote
with respect to that proposal.

                           (ITEM NO. 1 ON PROXY CARD)
 
     The Board is divided into three classes of directors serving staggered
three-year terms. Class II and Class III each have two directors and Class I has
three directors.
 
     At the meeting, Messrs. Conrad P. Albert and Robert J. Allison, Jr., Class
II directors, are to be elected for terms of three years, each to hold office
until the expiration of his term in 2000 and until his successor shall have been
elected and shall have qualified. It is the intention of the persons named in
the accompanying form of proxy to vote such proxy, unless otherwise instructed,
for the election of Messrs. Conrad P. Albert and Robert J. Allison, Jr. for
terms of three years. If either of these nominees should be unable to serve, the
proxies will be voted for the election of such other persons as shall be
determined by the persons named in the proxy, in accordance with their judgment.
 
     Messrs. Larry Barcus and James L. Bryan, Class III directors, were elected
by the stockholders in 1995 for terms of three years. Messrs. Ronald Brown and
John R. Gordon, Class I directors, were elected by the stockholders in 1996 to
each serve a three-year term. Mr. John R. Butler, Jr. was elected by the

TRANSACTIONS WITH MANAGEMENT AND OTHERS
 
     The Company purchases production, drilling and seismic data from
wholly-owned subsidiaries of GeoQuest International Holdings, Inc. In 1996, the
aggregate amount paid to Petroleum Information Corporation and Petroleum
Information (Canada), Ltd., was approximately $878,000. Mr. Butler, a director
of the Company, is Chairman of the Board and Chief Executive Officer of GeoQuest
International Holdings, Inc. and Senior Chairman of the subsidiaries. In
addition, the Company paid approximately $50,000 in 1996 to Houston Advance
Research Center for a seismic imaging project. Mr. Butler is Chairman of the
Houston Advance Research Center.
 
     During 1989, Anadarko Algeria Corporation ("Anadarko Algeria"), a
wholly-owned subsidiary of the Company, entered into an agreement with
Sonatrach, the national oil and gas enterprise of Algeria ("Sonatrach"), which
gives Anadarko Algeria the right to explore for and produce liquid hydrocarbons
in Algeria. Sonatrach is wholly-owned by the People's Democratic Republic of
Algeria and owns 99.9% of the capital stock of Sonatrach Petroleum Investment
Corporation (Ireland) Limited. In 1996, approximately $60,000 was paid to
Sonatrach for charges related to reservoir studies, laboratory services and well
testing services. As of December 31, 1996, a total of approximately $232 million
in exploration and development costs had been incurred by Anadarko Algeria of
which approximately $85 million was incurred in 1996.
 
     During 1996, Anadarko Algeria and Sonatrach entered into a contract with
Brown & Root Condor, SPA ("BRC") for the construction of an oil production

                           COMPENSATION OF DIRECTORS
 
     Directors who are not employees of the Company receive an annual retainer
of $35,000 for serving on the Board of Directors, plus $1,250 for attendance at
each meeting of the Board. In addition, non-employee directors receive an annual
retainer of $3,000 for serving on the Audit or the Compensation Committee, plus
$1,250 for each committee meeting attended. Non-employee directors who serve as
a Chairman of a committee receive an additional annual retainer of $3,000. All
directors are reimbursed for expenses incurred in attending Board and committee
meetings. Employees of the Company who are also directors do not receive a
retainer or fees for Board and committee meetings attended.
 
     The 1988 Stock Option Plan for Non-Employee Directors (the "1988 Plan") was
amended in 1994 to permit nonemployee directors to receive a portion of their
retainer and/or meeting fees in Common Stock. Under the 1988 Plan, each
non-employee director receives an initial grant of 10,000 options which vest
equally over a two-year period. In addition, on October 27 of each year, each
non-employee director is granted an option to purchase 5,000 shares of Common
Stock at the fair market value on such date. All outstanding options granted
under the 1988 Plan are options which do not constitute incentive stock options
("ISOs") within the meaning of the Internal Revenue Code of 1986, as amended
(the "Code") ("NQOs"). All outstanding options under the 1988 Plan are
exercisable no earlier than one year from the date of grant and expire 10 years
from the date of grant. Options may not be awarded or granted after October 26,
1998, or the earlier termination of the 1988 Plan.
 
     The Company has a Director Retirement Income Plan for its non-employee
directors. Directors having 10 or more years of service on the Board and having
attained age 65 will be eligible to receive retirement income equal to 60% of
the Director's annual retainer fee in effect as of the director's retirement
date from the Board. Directors having less than 10 years of service will accrue
a benefit of 6% per year of service of the Director's annual retainer fee in
effect as of such Director's retirement. Such retirement income will become
payable on the later of the Director's retirement date or age 65 and will be
payable in equal installments on a monthly basis during the life of the Director
with 120 months of payments guaranteed.
 
     The Company's Director Deferred Compensation Plan (the "Director Deferred
Plan") allowed non-employee directors to defer all or part of their Director
annual retainer fee and provided unfunded benefit payments in amounts related to
the amount of compensation deferred, age of the Director at the time the
compensation was deferred and accrued interest at 20% per annum. The Director
Deferred Plan provides in-service payments during the time the director is a
member of the Board and payments upon retirement, death, disability or the
attainment of age 65. There have been no deferrals under the Director Deferred
Plan since 1990.
 
            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Based solely upon a review of Forms 3 and 4 furnished to the Company during
its most recent fiscal year and Forms 5 furnished to the Company with respect to
its most recent fiscal year, the Company believes that all transactions by
reporting persons during the most recent fiscal year were reported on a timely
basis. Forms 5 reporting the automatic grant of stock options in 1995 under the
1988 Plan for Messrs. Albert, Barcus, Brown, Bryan and Gordon were not filed in
1995.
 
                   COMPENSATION AND BENEFITS COMMITTEE REPORT
                         ON 1996 EXECUTIVE COMPENSATION
 
     The Compensation Committee is comprised entirely of independent outside
directors and is responsible for establishing and administering the executive
compensation programs of the Company. These programs are designed to promote the
Company's strategic objectives, thereby enhancing stockholder value. This report
describes the compensation decisions made by the Compensation Committee during
1996 with respect to Anadarko's executive officers.
 
                                        6

COMPENSATION PHILOSOPHY OF THE COMPANY
 
     The key elements of Anadarko's executive compensation programs include base
salary, performance-based annual bonus and long-term stock incentive plans.
These plans have been developed to attract, reward and retain key personnel
critical to the long-term success of the Company. Anadarko's compensation
programs are designed to provide executive officers total compensation levels
above the average of the Company's competitive market with the opportunity to be
within the top quartile of a select peer group of comparable public oil and gas
companies, to the extent that Company and executive performance on an individual
and collective basis so warrants. In 1996, Mr. Allison's total compensation was
within the top quartile of the select peer group.
 
     Section 162(m) of the Code limits the deductibility by a company of
compensation in excess of $1 million paid to the Chief Executive Officer and the
next four highest paid officers during any fiscal year, unless such compensation
meets certain performance-based requirements. The Compensation Committee's
primary consideration in structuring the Company's compensation programs and in
determining the appropriateness of awards, is the achievement of the Company's
strategic business goals, taking into consideration competitive practice, market
economics and other factors. To the extent fulfilling these goals is consistent
with favorable tax treatment under section 162(m) of the Code, the Compensation
Committee is committed to making awards that qualify for the performance-based
deduction. The Company believes that the compensation paid for 1996 pursuant to
the Annual Incentive Bonus Plan (the "Incentive Plan") and the compensation in
1996 resulting from the exercise of stock options awarded under the 1993 Stock
Incentive Plan (the "1993 Plan") is deductible. Additionally, the Company
believes that with approval by stockholders of the proposed amendment to the
1993 Plan (see APPROVAL OF AN AMENDMENT TO THE 1993 STOCK INCENTIVE PLAN on page
15), compensation which may be paid in the future pursuant to the performance
shares awarded to Mr. Allison in 1996 will also qualify as deductible
compensation under section 162(m).
 
     The Performance Graph, contained in this proxy statement, compares
Anadarko's stock price performance over a five-year period against the S&P 500
Index and the Dow Jones Oil-Secondary index (a published index for the oil and
gas industry). The Dow Jones Oil-Secondary index provides a meaningful
comparison of Anadarko's total stockholder return against a consistent
representation of oil and gas companies with whom Anadarko competes for
investment dollars. The majority of these companies are also included in the
select peer group against which the Compensation Committee annually reviews the
total compensation and stock ownership of its executive officers. The analysis
of this select peer group focuses more specifically on those companies which are
similar in business segments and are considered potential competitors for the
Company's executive talent.
 
BASE SALARY
 
     Anadarko strives to be the best managed company within the oil and gas
industry, and structures its compensation programs to match pay with
performance. The Company's base salaries are targeted to be above the industry
average, taking into account scope of responsibilities and internal
relationships. Individual base salaries are determined by the Compensation
Committee based on their subjective evaluation of the executive's performance
and the length of time the executive has been in the position. Base compensation
is reviewed annually by the Compensation Committee and adjusted accordingly to
reflect each executive officer's contribution to the performance of the Company.
 
     Mr. Allison's annual base salary for 1996 was increased by the Compensation
Committee, effective January 1, as a result of his contribution to the Company's
outstanding financial and operational performance for 1995, which served to
enhance the value of the Company. In determining Mr. Allison's base compensation
against his comparable peers, the Compensation Committee considered Mr.
Allison's leadership and specific individual contributions to the Company's
continued growth during his 18 years as Anadarko's Chief Executive Officer.

ANNUAL INCENTIVE BONUS
 
     For 1996, executive officers were eligible to receive annual bonus
incentives under the Company's Incentive Plan. The Incentive Plan puts a
significant portion of compensation at risk by linking potential annual
compensation to the Company's achievement of specific performance goals. These
goals are established by the Compensation Committee at the beginning of each
calendar year.
 
     Under the Incentive Plan, a total bonus target is established for each
individual executive officer and other key employees, which ranges up to 80% of
base salary. This target is based upon the individual's position, level of
responsibility and ability to impact the Company's success. The individual
target is adjusted based on the Company's achievement of pre-established
performance goals. Individuals may receive up to 150% of their bonus target if
the Company exceeds the specified goals and, conversely, individuals may receive
a reduced bonus or no bonus payment if the Company does not attain the specified
goals.
 
     For 1996, the performance goals established by the Compensation Committee
included financial, operational and relative stock price performance criteria.
The financial criteria included (1) net income, and (2) cash flow, both of which
were measured against internal objectives. The operational criteria included the
comparison of (1) Anadarko's average five-year worldwide reserve replacement
measured against an internal objective, and (2) Anadarko's average five-year
worldwide cost of finding measured against the most recent available industry
average five-year worldwide cost of finding. The stock price performance
criteria included the comparison of Anadarko's relative stock price performance
for 1996 against the relative average stock price performance of a select group
of peer companies for the same period. Each performance goal, including the
specific criteria for such goal, was assigned a weight by the Compensation
Committee based upon the relative importance of each goal in increasing
stockholder value.
 
     Anadarko's operating performance for 1996 was one of the best in the
Company's history. The Company added over 113 million energy equivalent barrels
(EEBs) of reserves, increasing total reserves to 601 million EEBs. Reserve
replacement for 1996 was 299%, which resulted in the Company replacing annual
production volumes for the 15th consecutive year. In addition, Anadarko's
worldwide five-year cost of finding continues to be better than the most
recently published industry worldwide five-year average. The Company's financial
performance for the year yielded record results. Anadarko's overall performance
for 1996, as measured against the performance goals established by the
Compensation Committee, produced the maximum Corporate Performance Rating under
the Incentive Plan. As a result, the Compensation Committee approved a bonus for
Mr. Allison which represents 150% of his 80% bonus target.
 
STOCK PLANS
 
     The Company believes equity-based programs encourage long-term strategic
management and enhancement of stockholder value. To align the interests of
executive officers with those of stockholders, the Company may grant certain
stock-based awards under the 1993 Plan. The Compensation Committee believes
stock ownership is important to place executive officers in the same position as
stockholders with a commitment to the long-term success of Anadarko. Anadarko
has established stock ownership guidelines for executive officers of two and
one-half times base salary for Vice Presidents, three times base salary for
Senior Vice Presidents and five times base salary for the Chief Executive
Officer.
 
     The Compensation Committee periodically reviews competitive market data to
determine appropriate stock awards based on the executive's position and the
market value of the stock. In addition, the Compensation Committee considers
previous stock grants when determining grant size for executive officers. The
Compensation Committee awards stock options to ensure that the interests of
executives and stockholders are aligned. Stock options only produce value for
the executive if there is an increase in stock price which results in a
corresponding increase in value to the stockholder. Stock options are granted on
an annual basis at the fair market value of the Common Stock on the date of
grant.
 
     In early 1996, the Compensation Committee determined that the success of
the Company's long-term strategic objectives would best be supported by a stock
compensation program for Mr. Allison designed to increase stockholder value both
in absolute dollars and relative to the Company's peers, as well as encourage
 
                                        8
<PAGE>   11
 
his retention with the Company until normal retirement age. To accomplish these
objectives, the Committee granted Mr. Allison performance shares and 480,000
non-qualified stock options. The stock option grant vests over the next seven
years and encourages continued focus on increasing the stock price for the
stockholder. The performance share grant will only produce a payout if the
Company's total stockholder return relative to the Company's peers at the end of
a four-year or eight-year performance period meets the performance criteria
established by the Compensation Committee. The maximum potential payout under
this grant is 150,000 shares.
 
SUMMARY
 
     Anadarko's compensation strategy is to provide total compensation
commensurate with the Company's achievement of specific operational, financial
and strategic objectives and the long-term appreciation of Anadarko's stock
price. The Company believes a significant portion of executive compensation
should be directly and materially linked to the creation of value for
stockholders. The Compensation Committee believes the design of the Company's
total executive compensation program provides executives the incentive to
maximize long-term operational performance consistent with sound financial
controls and high standards of integrity. It is the Compensation Committee's
belief that this focus will ultimately be reflected in Anadarko's stock price
and stockholder return.
 
     The Compensation and Benefits Committee of the Board of Directors consists
of the following:
 
         Mr. Ronald Brown
         Mr. John R. Gordon
         Mr. Charles M. Simmons

(1) No SARs were granted in 1996.
 
(2) The exercise price equals the fair market value of the Common Stock on the
    date of grant.
 
(3) The dollar amounts under these columns are the results of calculation at 0%
    and at the 5% and 10% rates set by the Commission and are not intended to
    forecast possible future appreciation, if any, of the Company's stock price.
    The Company did not use an alternative formula for a grant date valuation,
    as the Company is not aware of any formula which will determine with
    reasonable accuracy a present value based on future unknown or volatility
    factors.
 
(4) The stock option granted on February 26, 1996, was granted under the
    Company's 1993 Plan. On August 16, 1996 and on February 26, 1997, 60,000
    options became exercisable. On each February 26 beginning in 1998 through
    2003, 60,000 will become exercisable. In the event of a "Change of Control"
    (as defined by the Plan) the Compensation Committee can take any one or more
    of the following actions: (i) provide for the acceleration of vesting; (ii)
    provide for the purchase of the option by the Company; (iii) make such
    adjustment as deemed appropriate; or (iv) cause such option to be assumed,
    or new rights substituted therefor, by the acquiring or surviving
    corporation.
 
(5) Stock options granted on October 30, 1996 were granted under the Company's
    1993 Plan. Fifty percent of the options become fully exercisable on October
    30, 1997 and 50 percent become fully exercisable on October 30, 1998. In the
    event of a "Change of Control" (as defined by the Plan) the Compensation
    Committee can take any one or more of the following actions: (i) provide for
    the acceleration of vesting; (ii) provide for the purchase of the option by
    the Company; (iii) make such adjustment as deemed appropriate; or (iv) cause
    such option to be assumed, or new rights substituted therefor, by the
    acquiring or surviving corporation.
 
(6) Shares owned by all stockholders on December 31, 1996. No gain to optionee
    is possible without an increase in stock appreciation which will benefit all
    stockholders commensurately. A 0% gain in stock price appreciation will
    result in no appreciation for the optionee.

</TABLE>
 
Subject to stockholder approval of the amendment to the 1993 Plan, Mr. Allison
was granted 100,000 performance shares with a maximum potential payout of
150,000 shares for the four-year performance period January 1, 1996 through
December 31, 1999. Payout of the performance shares will be determined by
comparing the Company's average quarterly total shareholder return ("TSR") over
the performance period to a select group of peer companies, designated at the
time of the grant, average quarterly TSR for the same period. Any company that
ceases to be traded during the performance period will be removed from the peer
company list and payout will be determined based on the remaining companies. No
companies may be added to the peer company list during the performance period.
At the end of the performance period, the Company and the peer companies shall
be ranked based on their TSR ranking. If the Company is in the top 25% of the
ranking, payout will be 150% of the shares granted. If the Company is average or
above, payout will be 100% of the shares granted. If the Company is below
average, no shares will be paid out. If all shares are not earned in the initial
four-year performance period they may be earned based on an eight-year
performance period, using the same performance criteria, beginning on January 1,
1996 through December 31, 2003. In the event of an eight-year performance
period, any shares paid out based on the four-year performance period will be
subtracted from any payout earned at the end of the eight-year performance
period. Upon cessation of employment resulting from death or disability during a
performance cycle, TSR will be calculated for the Company and the peer companies
using the closing stock price on the date employment ceases. Upon cessation of
employment resulting from a Change of Control, TSR will be calculated using the
closing stock price on the date of the Change of Control. The amount of payout
will be pro-rated based on the actual number of quarters completed (including
the quarter in which the event occurred). Upon cessation of employment as a
result of retirement, any payout will be made at the discretion of the
Compensation Committee. Payout under the 1993 Plan will be made in shares of
Common Stock of the Company.

</TABLE>
 
     The Retirement Plan provides benefits based on a length of service and a
final average pay formula including the Salary and Bonus columns of the Summary
Compensation Table. Messrs. Allison, Manley, Rose, Seitz and Abernathy,
respectively, have 23, 23, 19, 19 and 22 years of accrued service under the
Plan. An employee becomes vested in his benefit under the Retirement Plan at
completion of five years of vesting service, as defined in the Retirement Plan.
 
     The benefits payable under the Retirement Plan are subject to certain
limitations under the Code. For certain employees who may be affected by such
limits, the Company has a Retirement Restoration Plan (the "Restoration Plan")
to maintain total benefits upon retirement at approximately the levels shown in
the table above. The supplemental benefits provided under the Restoration Plan
will not be accorded certain of the favorable tax treatments that apply to
benefits paid under the existing Retirement Plan. Benefits under the Restoration
Plan are payable solely from the general assets of the Company.
 
          TERMINATION OF EMPLOYMENT AND CHANGE OF CONTROL ARRANGEMENTS
 
     The Company has Key Employee Change of Control Contracts (the "Severance
Contracts") with all current executive officers. The Severance Contracts provide
that in the event of a change in control, as defined in the Severance Contracts,
such individuals will receive certain benefits in the event of the termination
of their employment within five years of the effective date of such change in
control. Such benefits are provided unless such termination of employment is (i)
because of the death or retirement, except in certain circumstances, of the
executive, (ii) by the Company for cause or disability, or (iii) by the
executive other than for good reason (as defined in the Severance Contracts).
Generally, benefits payable under the terms of the Severance Contracts include a
lump-sum cash payment equal to (i) 2.9 times the highest total annualized
compensation paid during the three years ending with the year of such
participant's termination from the
 
                                       13
<PAGE>   16
 
Company (including base salary and the amount or value of any bonuses); (ii) the
amount of Company matching contributions which would have been made on the
participant's behalf had he continued to participate in the Anadarko Employee
Savings Plan and the Savings Restoration Plan for up to an additional three
years; (iii) the present value of the additional normal retirement benefit which
would have been received by the employee based on continued service through
normal retirement date and assuming an annual 6% increase in base salary; (iv)
the present value of the amounts of deferred compensation which would have been
received by the employee based on continued service through age 65 under each
deferred compensation agreement to which the participant was a party; and (v)
the value of any investments credited to the employee under the Savings
Restoration Plan. In addition, the Severance Contracts provide for a
continuation of various health care, disability and life insurance plans and
certain other benefits for a period of up to three years; and the payment of all
legal fees and expenses incurred by the employee in obtaining or enforcing any
right or benefit provided by the Severance Contracts. The Severance Contracts
also obligate the Company to pay an employee such cash amount as may be
necessary to restore any benefit diminution resulting directly or indirectly
from the assessment of any special excise taxes under section 280G of the Code
in respect to benefits provided under the Severance Contracts. In consideration
of these benefits the employee agrees, in the event a person seeks to effect a
change in control, not to leave the employ of the Company and to render services
commensurate with his position until such person has abandoned or terminated his
efforts or the change in control has occurred. The employee also agrees to
retain, in confidence, any and all confidential information known to him
concerning the Company and its business so long as such information is not
otherwise publicly disclosed. No amounts have been paid under the Severance
Contracts.
 
     The Employee Severance Pay Plan (the "Severance Plan") covers all of the
Company employees who are not covered by the Employment Contracts. The Severance
Plan provides that, in the event of a change in control, as defined in the
Severance Plan, employees will have certain benefits provided to them in the
event of the termination of their employment within three years after the
effective date of such change in control. Benefits are provided unless
termination of employment is (i) because of the death or retirement, except in
certain circumstances, of the employee; (ii) by the Company for cause or
disability; or (iii) by the employee other than for good reason, as defined in
the Severance Plan. The Severance Plan provides benefits that include a lump sum
cash payment based on salary and service ranging from a minimum of three months
to a maximum of two years salary; and a continuation of employee's medical and
dental insurance for six months. No amounts have been paid under the Severance
Plan.
 
     In the event of a "Change of Control", under the terms of the Company's
existing stock option plans, except for the 1993 Plan, all outstanding options
which were granted at least six months prior to the date of the "Change of
Control" shall be surrendered to the Company and the optionee shall receive a
cash payment in an amount equal to the number of shares of Common Stock subject
to the options multiplied by the difference between the fair market value of a
share of Common Stock on the date determined to be the date of cancellation and
surrender of such options and the option price. Under the 1993 Plan in the event
of a "Change of Control" the Compensation Committee can take one or more of the
following actions: (i) provide for the acceleration of vesting; (ii) provide for
the purchase of the option by the Company; (iii) make such adjustment as deemed
appropriate; or (iv) cause such option to be assumed, or new rights substituted
therefor, by the acquiring or surviving corporation.

           APPROVAL OF AN AMENDMENT TO THE 1993 STOCK INCENTIVE PLAN
                           (ITEM NO. 2 ON PROXY CARD)
 
     THE BOARD OF DIRECTORS RECOMMENDS THE APPROVAL OF THE AMENDMENT TO THE 1993
STOCK INCENTIVE PLAN (THE "AMENDMENT") WHICH AUTHORIZES THE GRANT OF PERFORMANCE
STOCK AWARDS BASED ON THE PERFORMANCE GOAL SPECIFIED IN THE AMENDMENT.
 
     The 1993 Plan was adopted by the Board on October 28, 1993 and approved by
stockholders on April 28, 1994. In December 1995, the Internal Revenue Service
("IRS") issued final regulations under section 162(m) of the Code. Section
162(m) of the Code limits to $1 million per year the tax deduction available to
public companies for certain compensation paid to certain employees subject to
an exemption for compensation which is "performance-based". The Company's intent
is to ensure that payouts of performance shares granted under the 1993 Plan
qualify for the exemption under section 162(m) of the Code.
 
     The 1993 Plan is intended to attract and retain executive personnel and
other key employees of the Company and its subsidiaries. In addition, the 1993
Plan is intended to allow the Compensation Committee the ability to use stock
and stock-related awards in the Company's overall compensation program. The
essential features of the Amendment and the 1993 Plan, as amended, are
summarized below. Approval by
 
                                       15
<PAGE>   18
 
affirmative votes of holders of a majority of shares of Common Stock present, or
represented, and entitled to vote is required for any payouts of performance
shares granted under the 1993 Plan and for the payouts to qualify for the
"performance-based" compensation exemption under section 162(m) of the Code.
 
AMENDMENT
 
     The Amendment to the 1993 Plan establishes performance criteria for the
granting of performance shares under the Plan. The Committee has the authority
to grant Performance Awards based upon the achievement of the specific
performance goals. The Committee shall establish at the time a Performance Award
is granted the performance period, which shall be equal in length to at least
four years, and the performance goals pursuant to which an Employee may earn and
be entitled to a payment under such Performance Award. The Committee shall also
establish a schedule or schedules setting forth the portion of the Performance
Award which will be earned or forfeited based on the degree of achievement, or
lack thereof, of the performance goals at the end of the relevant performance
period.
 
     The performance goals shall be based on the Company's TSR compared to
certain peer companies' TSR for the same period. During any performance period,
the Committee shall have the authority to adjust the performance goals in such
manner as the Committee, in its sole discretion, deems appropriate with respect
to such performance period; provided, however, that Performance Awards which are
designed to qualify for the performance-based exception of section 162(m) of the
Code, and which are held by "covered employees" (as such term is defined in the
regulations promulgated under section 162(m) of the Code), may not have any term
or condition of such Award changed in a manner that would produce a greater
benefit.
 
     Stockholders must approve the material terms of the performance goals
before any compensation is paid to certain employees' granted Performance
Awards. One Performance Award was granted in 1996. For the terms of that grant
see LONG-TERM INCENTIVE PLANS -- AWARDS IN LAST FISCAL YEAR on page 12.
 
     The maximum aggregate number of Performance Award shares that may be issued
to an employee for payment of compensation based on a Performance Award grant
shall not exceed 150,000 shares for any performance period. Performance Award
compensation payments may be paid in a lump sum or in installments, in cash,
shares or in any combination thereof, following the close of the performance
period or, in accordance with procedures established by the Committee, on a
deferred basis.
 
SUMMARY OF THE 1993 STOCK INCENTIVE PLAN AS AMENDED
 
TYPES OF AWARDS
 
     The 1993 Plan permits the granting of any or all of the following types of
awards: (1) stock options, including ISOs; (2) SARs in tandem with stock options
or freestanding; (3) restricted stock; (4) performance awards; (5) stock
compensation awards; and (6) other stock-based awards.
 
ELIGIBILITY FOR PARTICIPATION
 
     All key employees, including employee directors and officers of the Company
or any affiliate of the Company, are eligible for participation under the 1993
Plan. While the concept of "key employee" eligible to participate in the 1993
Plan is necessarily flexible, approximately 150 employees (including a total of
15 executive officers) are considered to fall within this category.
 
ADMINISTRATION
 
     The 1993 Plan is administered by the Compensation Committee composed of
disinterested, outside directors appointed by the Board. The Compensation
Committee selects key employees who will receive awards, determines the type and
terms of awards to be granted, and interprets and administers the Plan. Unless
otherwise expressly provided in the 1993 Plan, all decisions under or with
respect to the 1993 Plan shall be within the sole discretion of the Compensation
Committee and are final.
 
                                       16
<PAGE>   19
 
AMENDMENT AND TERMINATION
 
     The Board may terminate or amend the 1993 Plan without stockholder
approval, except that stockholder approval is required for any amendment which
would increase the number of shares available for grant, decrease the minimum
exercise price or otherwise cause the 1993 Plan to cease to qualify for any tax
or regulatory exemption, status or requirement.
 
TERM OF THE PROGRAM
 
     The 1993 Plan will terminate on October 28, 2003, after which time no
additional awards may be made under the 1993 Plan.
 
SHARES SUBJECT TO PROGRAM
 
     Subject to adjustment as described more fully below, 4,000,000 shares of
Common Stock may be awarded under the 1993 Plan, provided, however, that no more
than 800,000 shares of the shares specified shall be issued as restricted stock.
The maximum aggregate number of shares available for options and SARs to any
executive officer during the term of the 1993 Plan is 20 percent of the number
of shares with respect to which awards may be granted under the 1993 Plan.
 
STOCK OPTIONS
 
     Stock options granted under the 1993 Plan are subject to the terms and
conditions determined by the Compensation Committee, except that (i) no options
may be granted after the termination of the 1993 Plan; (ii) the option exercise
price cannot be less than 100 percent of fair market value of a share of Common
Stock at the time the option is granted; and (iii) no option may be exercised
more than 10 years after it is granted. ISOs may be granted provided they meet
the requirements of the Code.
 
     The Compensation Committee shall determine the form in which payment of the
exercise price may be made, including cash, shares of Common Stock, other
securities or other property, or any combination thereof, having a fair market
value on the exercise date equal to the relevant exercise price.
 
STOCK APPRECIATION RIGHTS
 
     An SAR may be granted in tandem with another award, in addition to another
award, or freestanding and unrelated to another award. The grant price of an SAR
shall not be less than 100 percent of fair market value of a share of Common
Stock at the time the SAR is granted. The Compensation Committee may impose such
conditions or restrictions on the exercise of any SAR as it shall deem
appropriate.
 
RESTRICTED STOCK
 
     The Compensation Committee shall determine the employees to whom Restricted
Stock shall be granted, the number of shares of Restricted Stock to be granted
to each participant, the duration of the restriction period, the conditions
under which the Restricted Stock may be forfeited to the Company and other terms
and conditions of awards of Restricted Stock. Restricted Stock may not be
disposed of by the participant until the restrictions specified in the award
expire. The participant will have, with respect to Restricted Stock, the right
to vote the shares and receive any cash dividends. Except as otherwise
determined by the Compensation Committee, upon termination of a participant's
employment for any reason during the restriction period, all Restricted Stock
shall be forfeited by the participant.

STOCK COMPENSATION
 
     The Compensation Committee shall have the authority to pay all or a portion
of any amounts payable under any compensation program of the Company in shares
of Common Stock. The number and type of shares to be distributed in lieu of the
cash compensation, as well as the terms and conditions of any such stock
compensation, shall be determined by the Compensation Committee.
 
OTHER STOCK-BASED AWARDS
 
     The Compensation Committee may grant other forms of awards based on,
payable in, or otherwise related in whole or in part to Common Stock under the
1993 Plan. Subject to the terms of the 1993 Plan, the Compensation Committee
shall determine the terms and conditions of any such other stock-based awards.
 
CHANGE OF CONTROL
 
     In the event of a "Change of Control" as defined in the 1993 Plan, the
Compensation Committee may take any one or more of the following actions in
connection with any awards made under the 1993 Plan: (i) accelerate the exercise
or vesting date; (ii) provide for the purchase, in cash, of such award; (iii)
make adjustments to such award; or (iv) cause any outstanding award to be
assumed, or a new right substituted therefor, by the acquiring or surviving
corporation.
 
ADJUSTMENTS
 
     In the event the Compensation Committee determines that any dividend or
other distribution, recapitalization, stock split, reverse stock split,
reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or exchange of shares of Common Stock or other similar corporate
transaction or event affects the Common Stock such that an adjustment is
determined by the Compensation Committee to be appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended under the
1993 Plan, then the Compensation Committee shall adjust any or all of the
awards.

                         ANADARKO PETROLEUM CORPORATION
                           1993 STOCK INCENTIVE PLAN
 
     WHEREAS, ANADARKO PETROLEUM CORPORATION (the "Company"), has heretofore
adopted the 1993 Stock Incentive Plan (the "Plan"); and
 
     WHEREAS, the Company desires to amend the Plan;
 
     NOW, THEREFORE, the Plan shall be amended as follows, effective as of
January 1, 1996:
 
     1. Section 2 shall be amended by replacing the definition of "Employee" in
its entirety with the following definition:
 
          "'Employee' shall mean any executive officer or other key employee of
     the Company or any Affiliate."
 
     2. Section 6 (d) shall be replaced in its entirety by the following:
 
          "(d) Performance Awards. The Committee shall have authority to grant
     Performance Awards which shall consist of a right, denominated in Shares,
     and shall confer on the holder thereof compensation rights based upon the
     achievement of the performance goals. The maximum aggregate number of
     Performance Award Shares that may be issued to an Employee for payment of
     compensation based on a Performance Award grant shall not exceed 150,000
     Shares for any performance period.
 
             (i) Terms and Conditions. Subject to the terms of the Plan, the
        Committee shall establish at the time a Performance Award is granted the
        performance period, which shall be equal in length to at least four (4)
        years, and the performance goals pursuant to which an Employee may earn
        and be entitled to a payment under such Performance Award. The Committee
        shall also establish a schedule or schedules setting forth the portion
        of the Performance Award which will be earned or forfeited based on the
        degree of achievement, or lack thereof, of the performance goals at the
        end of the relevant performance period. The performance goals shall be
        based on the Company's total shareholder return compared to peer
        companies' total shareholder return for the same period. During any
        performance period, the Committee shall have the authority to adjust the
        performance goals in such manner as the Committee, in its sole
        discretion, deems appropriate with respect to such performance period;
        provided, however, that Performance Awards which are designed to qualify
        for the performance-based exception of Section 162(m) of the Code, and
        which are held by "covered employees" (as such term is defined in the
        regulations promulgated under Section 162(m) of the Code), may not have
        any term or condition of such Award changed in a manner that would
        produce a greater benefit.
 
             (ii) Payment of Performance Awards. Performance Award compensation
        payments may be paid in a lump sum or in installments, in cash, Shares
        or in any combination thereof, following the close of the performance
        period or, in accordance with procedures established by the Committee,
        on a deferred basis."
 
     3. Section 9 shall be amended by adding the following new subsection:
 
          "(l) Shareholder Approval. Shareholders must approve the material
     terms of the performance goals described in Section 6(d) before any
     compensation is paid to a "covered employee" (as such term is defined in
     the regulations promulgated under Section 162(m) of the Code) based upon a
     Performance Award granted under such section."
 
     4. As amended hereby, the Plan is specifically ratified and reaffirmed.
