ITEM 1. BUSINESS
 
    The Company was incorporated in 1970 and is engaged in oil and gas
exploration, development and production activities on its properties located
offshore in the Gulf of Mexico, onshore in selected areas in New Mexico, Texas
and Louisiana, and internationally, primarily in the Gulf of Thailand and in
Canada. As of December 31, 1998, the Company had interests in 105 lease blocks
offshore Louisiana and Texas, approximately 419,000 gross acres onshore in the
United States and Canada, approximately 847,000 gross acres offshore in the
Kingdom of Thailand and approximately 113,000 gross acres in the British North
Sea. On August 17, 1998, a wholly owned subsidiary of the Company merged with
and into Arch Petroleum Inc. ("Arch") in a stock-for-stock tax-free merger
accounted for as a purchase.
 
    As of December 31, 1998, four significant operating areas, including the
Outer Continental Shelf area of the Gulf of Mexico offshore Louisiana and Texas
in water depths less than 600 feet (the "Shelf") and on the continental slope in
water depths ranging from 600 feet to approximately 4,500 feet (the "Continental
Slope"), the Permian Basin area in New Mexico and Block B8/32 Concession in the
Kingdom of Thailand (the "Thailand Concession), accounted for approximately 76%
of the Company's estimated proved natural gas reserves, approximately 97% of the
Company's estimated proved oil, condensate and natural gas liquids reserves,
approximately 78% of the Company's 1998 natural gas production and 94% of the
Company's 1998 oil, condensate and natural gas liquids production. Reserves, as
estimated by Ryder Scott, and production data, as estimated by the Company, for
the four significant operating areas are shown in the following table. The
percentages presented on the table are the percentage of the Company's total net
proved natural gas and liquids reserves, natural gas and liquids production and
total proved reserves, respectively.

DOMESTIC OFFSHORE OPERATIONS
 
    Historically, the Company's interests have been concentrated in the Gulf of
Mexico, where approximately 26% of the Company's proved reserves were located as
of December 31, 1998. During 1998, approximately 48% of the Company's natural
gas production and approximately 55% of its oil and condensate production was
from its domestic offshore properties, contributing approximately 53% of the
Company's consolidated oil and gas revenues. Although the Company's operations
were historically focused on the Shelf where it owns interests in 89 lease
blocks, the Company has recently expanded its exploration efforts further
offshore into the Continental Slope where the Company currently has interests in
16 lease blocks with water depths that range from 600 feet to approximately
4,400 feet.
 
                                       4
<PAGE>
    LEASE ACQUISITIONS
 
    The Company has participated, either on its own or with other companies, in
bidding on and acquiring interests in federal and state leases offshore in the
Gulf of Mexico since December 1970. As a result of such purchases and subsequent
activities, as of December 31, 1998, the Company owned interests in 97 federal
leases and 8 state leases offshore Louisiana and Texas. Federal leases generally
have primary terms of five, eight or ten years, depending on water depth, and
state leases generally have terms of three or five years, depending on location,
in each case subject to extension by development and production operations.
 
    As part of its strategy, the Company intends to continue an active lease
evaluation program in the Gulf of Mexico in order to identify exploration and
exploitation opportunities. During 1998, the Company was successful in acquiring
interests in four lease blocks through federal Outer Continental Shelf oil and
gas lease sales and one lease block by assignment from a third party. As in the
case of prior sales, the extent to which the Company participates in future
bidding on federal or state offshore lease sales will depend on the availability
of funds and its estimates of hydrocarbon deposits, operating expenses and
future revenues which reasonably may be expected from available lease blocks.
Such estimates typically take into account, among other things, estimates of
future hydrocarbon prices, federal regulations, and taxation policies applicable
to the petroleum industry. It is also the Company's objective to acquire certain
producing leasehold properties in areas where additional low-risk drilling or
improved production methods by the Company can provide attractive rates of
return.
 
    EXPLORATION AND DEVELOPMENT
 
    The scope of exploration and development programs relating to the Company's
offshore interests is affected by prices for oil and gas, and by federal, state
and local legislation, regulations and ordinances applicable to the petroleum
industry. The Company's domestic offshore capital and exploration expenditures
for 1998 were approximately $68,000,000 (excluding approximately $5,000,000 of
net property acquisitions), or 21% lower than the Company's domestic offshore
capital and exploration expenditures of approximately $86,300,000 for 1997
(excluding approximately $900,000 of net property acquisitions) and 26% lower
than the Company's domestic offshore capital and exploration expenditures of
approximately $92,400,000 for 1996. The decrease in the Company's domestic
offshore capital and exploration expenditures for 1998, compared with 1997 and
1996, resulted primarily from the Company's decision to decrease its drilling
activity in light of poor oil and gas prices and a decrease in construction and
installation of offshore platforms, pipelines and other facilities. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
    Leases acquired by the Company and other participants in its bidding groups
are customarily committed, on a block-by-block basis, to separate operating
agreements under which the appointed operator supervises exploration and
development operations for the account and at the expense of the group. These
agreements usually contain terms and conditions which have become relatively
standardized in the industry. Major decisions regarding development and
operations typically require the consent of at least a majority (in working
interest) of the participants. Because the Company generally has a meaningful
working interest position, the Company believes it can significantly influence
(but not always control) decisions regarding development and operations on most
of the leases in which it has a working interest even though it may not be the
operator of a particular lease. The Company is the operator on all or a portion
of 27 of the 105 offshore leases in which it had an interest on December 31,
1998.
 
    Platforms and related facilities are installed on an offshore lease block
when, in the judgment of the lease interest owners, the necessary capital
expenditures are justified. A decision to install a platform generally is made
after the drilling of one or more exploratory wells with contracted drilling
equipment. Platform costs vary depending on, among other factors, the number of
slots, water depth, currents, and sea floor conditions. Over the four years
ended December 31, 1998, the gross construction and installation cost of
production platforms and related facilities located on the Shelf in which the
Company shared a portion of the construction costs based on its ownership
interest in the development ranged from approximately $3,000,000 to
approximately $16,500,000. Wells, platforms and related facilities are typically
much more
 
                                       5
<PAGE>
expensive on the Continental Slope. The Company is currently participating in
the construction of one platform, one sub-sea development and related facilities
on the Continental Slope at a total capital commitment of $204,045,000 dollars
($30,341,000 net to the Company's working interest), of which approximately 38%
has been incurred through December 31, 1998. The Company believes that future
development projects on the Continental Slope may require similar capital
commitments, each of which must be justified in the then current and anticipated
future product price environment. In order to better manage the risks of large
projects on the Continental Slope, the Company generally seeks to have a smaller
ownership interest in these lease blocks than it averages in shallower waters.
 
    SIGNIFICANT DOMESTIC OFFSHORE OPERATING AREAS DURING 1998
 
    OUTER CONTINENTAL SHELF.  The Outer Continental Shelf has been an important
part of the Company's operations since the first lease in that area was
purchased in 1970 and production began in 1973. As of December 31, 1998, the
Company held interests in 89 blocks on the Shelf. The Company currently has 215
oil and gas wells producing from multiple reservoirs and horizons on the Shelf.
During 1998, the Company participated in the drilling of five wells on the
Shelf, the setting of one production platform and related facilities and the
upgrading of three platforms.
 
    CONTINENTAL SLOPE.  Since 1996 when the Company acquired its first interest
in a lease block in the Continental Slope, the Company has been increasingly
active in this area. As of December 31, 1998, the Company owns interests in 16
blocks in the Continental Slope and has interests in five wells that it has
drilled there, including three that were drilled in 1998. The Company is
currently participating in the construction of one platform and related
facilities at Viosca Knoll Blocks 780 and 823, and one subsea facility on Garden
Banks 367, on the Continental Slope.
 
ONSHORE OPERATIONS
 
    The Company has onshore division staffs in Houston and Midland, Texas and
Calgary, Canada. Its onshore activities are concentrated in known oil and gas
provinces, principally the Permian Basin area of southeastern New Mexico, West
Texas and Northwest Texas, in the onshore Gulf Coast areas of South Texas, East
Texas and South Louisiana and in Alberta and British Columbia in Canada. The
Company conducts its onshore operations in the United States directly and
through its wholly owned subsidiary Arch. The Company conducts its operations in
Canada through its wholly-owned subsidiary, Pogo Canada Ltd. See "--Significant
Onshore Operating Areas During 1998."
 
    LEASE ACQUISITIONS
 
    Commencing in 1995 and continuing into 1998, the Company increased its
activities in the onshore Gulf Coast areas of East Texas and South Louisiana
through its participation in several large proprietary 3-D seismic surveys, in
connection with which the Company typically purchases an option to acquire an
interest in the acreage covered by the 3-D seismic survey. As it has in recent
years, in 1998 the Company also successfully participated in various onshore
federal, state and provincial lease sales and acquired interests in prospective
acreage from private individuals. As of December 31, 1998, the Company held
interests in approximately 303,000 gross (151,000 net) acres onshore in the
United States and 117,000 gross (51,000 net) acres in Canada, an increase of
approximately 76% from year end 1997. The increase in acreage is primarily
related to the Company's acquisition of Arch and, to a lesser extent, the
Company's successful participation in the lease sales and private property
acquisitions described above, that was partially offset by the sale of certain
properties that it no longer considered strategic and the expiration of leases
in the ordinary course of business.
 
    EXPLORATION AND DEVELOPMENT
 
    The Company's primary drilling objective in the Permian Basin is the Brushy
Canyon (Delaware) formation which generally produces oil from depths of 6,000 to
9,000 feet. Since the Company began exploring in the Brushy Canyon (Delaware)
formation in October 1989, it has participated in drilling 389
 
                                       6
<PAGE>
wells in the Permian Basin, West and Northwest Texas areas through December 31,
1998, including 32 wells in 1998. See "--Significant Domestic Onshore Operating
Areas During 1998."
 
    In Southwest Louisiana, the Company participated in drilling 20 wells since
1996, including seven wells in 1998, to test various prospects, primarily in the
Hackberry and Yegua formations, almost all of which were identified on
proprietary 3-D seismic surveys that the Company and its industry partners have
acquired since 1995.
 
    Onshore reserves as of December 31, 1998, accounted for approximately 31% of
the Company's total proved reserves. During 1998, approximately 29% of the
Company's natural gas production and 31% of its oil and condensate production
was from its onshore properties, contributing approximately 30% of the Company's
consolidated oil and gas revenues.
 
    The Company generally conducts its onshore activities through joint ventures
and other interest-sharing arrangements with major and independent oil
companies. The Company operates many of its own onshore properties using
independent contractors.
 
    The Company's onshore capital and exploration expenditures were
approximately $48,800,000 (excluding approximately $133,100,000 of net property
acquisitions, including approximately $131,500,000 related to the acquisition of
Arch) for 1998, or 19% lower than the Company's onshore capital and exploration
expenditures of approximately $60,000,000 (excluding approximately $1,700,000 of
net property acquisitions) for 1997 and 4% higher than the Company's onshore
capital and exploration expenditures of approximately $47,000,000 (excluding
approximately $3,800,000 of net property acquisitions) for 1996. The decrease in
the Company's onshore capital and exploration expenditures for 1998, compared to
1997, resulted primarily from the Company's decision to curtail non-essential
drilling in light of poor oil and gas prices, that was not entirely offset by
capital and exploration expenditures in Canada where the Company acquired its
interest in Pogo Canada Ltd. in August 1998. The increase in capital and
exploration expenditures for 1998, compared to 1996, primarily related to
capital and exploration expenditures in Canada where the Company acquired an
interest during 1998 as part of the Arch acquisition.
 
    SIGNIFICANT ONSHORE OPERATING AREAS DURING 1998
 
    NEW MEXICO.  The Company believes that during the past six years it has been
one of the most active companies drilling for oil and natural gas in the
southeastern New Mexico (Lea and Eddy Counties) portion of the Permian Basin
where the Company has interests in over 105,000 gross acres. The Company's
primary drilling objective is the Brushy Canyon (Delaware) formation. Fields in
the Brushy Canyon (Delaware) formation in the southeastern New Mexico portion of
the Permian Basin are generally characterized by production from relatively
shallow depths (6,000 to 9,000 feet), multiple producing zones in most wells and
relatively high initial rates of production (frequently equaling the top field
allowables which typically range from 142 Bbls to 230 Bbls per day, depending on
the depth of production from the field). The Company has achieved rapid cost
recovery with respect to its New Mexico wells drilled to date because of
relatively low capital costs and high initial rates of production.
 
    LOPENO FIELD.  The Company acquired its initial interest in the Lopeno Field
in 1983. The Lopeno Field is located within 40 miles of the border with Mexico,
in 1983. As of December 31, 1998, the Company had interests in 29 producing
wells in the Lopeno Field. The Lopeno Field produces from over 20 upper Wilcox
sandstone reservoirs ranging in depth up to 12,500 feet. In late 1998, the
Company decided to sell its interest in the Lopeno Field as part of its asset
rationalization efforts. The Company currently expects to sell its interest by
March 15, 1999, effective back to January 1, 1999. Proceeds from the sale will
be used to reduce the Company's total debt and for general corporate purposes.
 
INTERNATIONAL OPERATIONS
 
    The Company has conducted international exploration activities since the
late 1970's in numerous oil and gas areas throughout the world. Currently, the
Company maintains an office in Bangkok, Thailand from which it directs field
operations on the Thailand Concession through its wholly owned subsidiary
 
                                       7
<PAGE>
Thaipo Limited ("Thaipo"). Thaipo currently owns, directly or indirectly, a
46.34% working interest in the entire Thailand Concession. The remainder of the
working interest is owned, directly or indirectly by Thai Romo Ltd. (46.34%), a
subsidiary of Rutherford-Moran Oil Corporation ("RMOC"), and Palang Sophon
Limited ("Palang") (7.32%). RMOC has entered into an agreement to merge with,
and become, a wholly owned subsidiary of Chevron Corporation ("Chevron"). It is
the Company's understanding that Chevron will also acquire a majority of the
stock of Palang. Based on publicly available information and communications with
Chevron, RMOC and Palang, it is the Company's current understanding that
Chevron's merger with RMOC, and its acquisition of a majority interest in
Palang, will be consummated on or shortly after March 17, 1999. Following these
transactions, Chevron will own or control, directly or indirectly, 53.66% of the
working interests in the Thailand Concession. Thaipo is currently the operator
of the Thailand Concession, pursuant to the joint operating agreement governing
the Thailand Concession and as designated by the government of Thailand. Subject
to approval by the government of Thailand and the agreement of the parties to
the joint operating agreement, Thaipo has agreed to transfer operatorship to a
subsidiary of Chevron on or about September 30, 1999. In addition, Chevron has
agreed to lend funds to RMOC to cover its cash call obligations under the joint
operating agreement until Chevron's merger with RMOC is consummated. As of
December 31, 1998, the Company's proved reserves located in the Kingdom of
Thailand accounted for approximately 44% of the Company's total proved reserves.
During 1998, approximately 29% of the Company's natural gas production and 31%
of its oil and condensate production came from its operations on the Thailand
Concession, contributing approximately 17% of the Company's consolidated oil and
gas revenues.
 
    EXPLORATION AND DEVELOPMENT
 
    The Company's international capital and exploration expenditures were
approximately $107,400,000 for 1998, or 22% higher than the Company's
international capital and exploration expenditures of approximately $88,300,000
for 1997 (excluding approximately $28,600,000 of net property acquisitions) and
67% higher than the Company's international capital and exploration expenditures
of approximately $64,400,000 (excluding approximately $4,200,000 of net property
acquisitions) for 1996. The increase in the Company's international capital and
exploration expenditures for 1998, compared to 1997 and 1996, resulted primarily
from increased platform and facilities construction costs related to development
of the Benchamas Field and increased drilling activity in the Tantawan and
Benchamas Fields. Substantially all of the Company's international capital and
exploration expenditures for 1998 were related to the Company's license in the
Kingdom of Thailand. On December 1, 1998, the Company together with two joint
partners, were successful in obtaining a license from the United Kingdom
governing approximately 113,000 acres in the British sector of the North Sea.
Terms of the license provided for a minimum work commitment that will involve
the acquisition, processing and interpretation of 3-D seismic data over the
block. The initial exploratory term of this license expires on December 1, 2004,
unless otherwise extended or a production license is granted. In addition, the
Company continues to evaluate other international opportunities that are
consistent with the Company's international exploration strategy and expertise.
 
    Platforms are installed on the Thailand Concession in fields where, in the
judgment of Thaipo and its joint venture partners, the necessary capital
expenditures are justified. A decision to install a platform generally is made
after the drilling of one or more exploratory wells with contracted drilling
equipment and the area where the platform would be located has been designated a
production area by the government of the Kingdom of Thailand. See "--Contractual
Terms Governing the Thailand Concession and Related Production." Platforms are
used to accommodate both development drilling and additional exploratory
drilling. Over the four years ended December 31, 1998, the gross cost of the
first five production platforms and related facilities in the Tantawan Field has
averaged approximately $20,000,000. The Company is currently participating in
the construction of platforms and related facilities for the Benchamas Field at
a total capital commitment of $267,470,000 dollars ($123,946,000 net to the
Company's working interest), of which approximately 67% has been incurred
through December 31, 1998. The Company and its joint venture partners have been
working to employ advanced platform facility design and advanced drilling and
completion techniques, including slimhole, batch and horizontal drilling, to
reduce the cost of developing the Thailand Concession. The Company believes that
future satellite platforms and related facilities may
 
                                       8
<PAGE>
be installed for as little as approximately $13,000,000 per platform in the
future. Platform costs vary and more (or less) expensive platforms could be
required in the future depending on, among other factors, the number of slots,
water depth, currents, and sea floor conditions. See "--Significant
International Operating Areas During 1998; Tantawan Field."
 
    SIGNIFICANT INTERNATIONAL OPERATING AREAS DURING 1998
 
    TANTAWAN FIELD.  In August 1995, at the request of Thaipo and its joint
venture partners, the government of Thailand designated a portion of the
Thailand Concession comprising approximately 68,000 acres as the Tantawan
production area or the "Tantawan Field." Initial production from the Tantawan
Field commenced on February 1, 1997. Currently, there are 28 wells producing
from four platforms. The Company is currently planning to install a fifth
platform in the Tantawan Field from which production is expected to commence in
the first half of 1999.
 
    Oil and gas production from the Tantawan Field is gathered through pipelines
from the platforms into a Floating Production Storage and Offloading system (an
"FPSO") named the "Tantawan Explorer." The FPSO is a converted oil tanker with a
capacity of slightly less than 1,000,000 Bbls, that is moored in the Tantawan
Field, on which hydrocarbon processing, separation, dehydration, compression,
metering and other production related equipment is installed. Following
processing on board the FPSO, natural gas produced from the field is delivered
to The Petroleum Authority of Thailand ("PTT") through an export pipeline. Oil
and condensate produced from the field is stored on board the FPSO and
transferred to shore by oil tanker. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources."
 
    BENCHAMAS FIELD AND THE MALIWAN PRODUCTION AREA.  In July 1997, the
government of Thailand designated another portion of the Thailand Concession
comprising approximately 102,000 acres as the Benchamas and Pakakrong production
area or the "Benchamas Field." In September 1997, the government of Thailand
designated an additional 91,000 acres of the Thailand Concession as the Maliwan
production area. Current development plans call for the staged development of
these fields, with the Benchamas Field to be brought on production first. The
Benchamas Field development plan contemplates the initial installation of three
production platforms, with natural gas and oil from these platforms delivered by
undersea pipeline to a central processing and compression platform where the
oil, condensate and natural gas will be processed and separated. The natural gas
will then be sold to PTT and delivered into export pipelines for transportation
to shore, while the oil and condensate produced from the field will be stored on
board a Floating Storage and Offloading system ("FSO"), known as the "Benchamas
Explorer," for sale and ultimate transfer to shore by oil tanker. The FSO will
be moored in the Benchamas Field. Its capacity will be approximately 1,400,000
Bbls of crude and condensate. The Benchamas Field's current development plan
calls for initial production to commence in the third quarter of 1999 with
production from the Maliwan production area to begin in late 2001.
 
    OTHER AREAS.  In addition to the above mentioned fields, Thaipo and its
joint venture partners have identified other potentially promising areas on the
Thailand Concession. Since acquiring their interest in the Thailand Concession,
Thaipo and its joint venture partners have acquired 3-D seismic surveys covering
approximately 673,650 acres of the Thailand Concession, including 221,650 acres
during the fourth quarter of 1997 over what is known as the Jarmjuree area.
Through February 1, 1999, Thaipo and its joint venture partners have drilled
eight wells on areas of the Thailand Concession that are not currently
designated as production areas. Interpretation of the data provided by these
wells and 3-D seismic data covering these areas is ongoing. Thaipo and its joint
venture partners also currently plan to drill additional exploration wells in
these areas during 1999.
 
    CONTRACTUAL TERMS GOVERNING THE THAILAND CONCESSION AND RELATED PRODUCTION
 
    The Thailand Concession was granted in August 1991. The exploratory term for
those portions of the Thailand Concession that have not yet been designated a
production area (comprising approximately 474,000 acres) expires July 31, 2000.
For those portions of the Thailand Concession that have been designated as
production areas, the initial production period term is 20 years, which is also
subject to
 
                                       9
<PAGE>
extension, generally for a term of ten years. See also "--Miscellaneous; Sales."
Currently, the Tantawan, Maliwan, and Benchamas and Pakakrong areas have been
designated as production areas. Subject to governmental approval, other portions
of the Thailand Concession may be designated production areas in the future.
 
    Production resulting from the Thailand Concession is subject to a royalty
ranging from 5% to 15% of oil and gas sales, plus certain fixed U.S. dollar
amounts payable at specified cumulative production levels. Revenue from
production in Thailand is also subject to income taxes and other similar
governmental charges including a Special Remuneratory Benefit tax ("SRB").
 
    Thaipo and its joint venture partners have entered into a thirty-year Gas
Sales Agreement with PTT (the "Gas Sales Agreement"), governing gas production
from the Tantawan Field and anticipated gas production from the Benchamas Field.
The terms of the Gas Sales Agreement currently include a minimum daily contract
quantity ("DC") of 85 MMcf per day, which the Company currently anticipates will
continue until the Benchamas Field commences production, at which time the DC
will, subject to certain exceptions, be based on a percentage of the remaining
proved reserves, but in any event, will not be less than 125 MMcf per day. The
DC is the minimum daily volume that PTT has agreed to take, or pay for if not
taken, under the agreement. Likewise, Thaipo and its joint venture partners are
subject to certain penalties if they are unable to meet the DC, principal among
which is a decrease in sales price of up to 25% of the then current sales price.
As a result of declining production from existing wells in the Tantawan Field,
the need to shut-in existing wells while drilling additional wells from the same
platform, and the decision to emphasize oil and condensate production from the
Tantawan Field, commencing on October 1, 1998, the Company and its joint venture
partners are currently delivering less natural gas than is being nominated by
PTT under the Gas Sales Agreement. This could result in the Company receiving
only 75% of the current contract price on a portion of its future natural gas
sales to PTT. The Company is taking actions that it currently believes will
minimize the penalty that it will incur on future gas sales to PTT by increasing
production from the Tantawan Field. The contract sales price is subject to
automatic semi-annual adjustments based upon a formula which takes into account
changes in: Singapore fuel oil prices; the U.S. Bureau of Labor Statistics
Oilfield Machinery and Tool Index; the Thai wholesale producer price index; and
the U.S./Thai currency exchange rate. However, the Gas Sales Agreement provides
for adjustment on a more frequent basis in the event that certain indices and
factors on which the price is based fluctuate outside a given range. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Results of Operations; Foreign Currency Transaction Gain (Loss)" and
"--Liquidity and Capital Resources; Other Matters; Southeast Asia Economic
Issues."
 
MISCELLANEOUS
 
    OTHER ASSETS
 
    The Company and a subsidiary, Pogo Offshore Pipeline Co., own interests in
eight pipelines (excluding field gathering pipelines) through which offshore
hydrocarbon production is transported. Through a wholly-owned subsidiary,
Saginaw Pipeline Company, L.C. ("Saginaw"), which the Company acquired in its
merger with Arch, the Company owns and operates the Saginaw pipeline, a six
inches in diameter pipeline that runs from just outside of Fort Worth, Texas to
Wichita Falls, Texas. Industrial Natural Gas, L.C., a subsidiary of Saginaw,
markets the sale and transmission of natural gas through the Saginaw pipeline.
 
    In addition, the Company owns an approximately 19% interest in a cryogenic
gas processing plant near Erath, Louisiana, which entitles it to process up to
186 MMcf of natural gas and 5,478 Bbls of natural gas liquids per day. The plant
is not currently operating at full capacity.
 
    SALES
 
    The marketing of offshore oil and gas production is subject to the
availability of pipelines and other transportation, processing and refining
facilities, as well as the existence of adequate markets. As a result, even if
hydrocarbons are discovered in commercial quantities, a substantial period of
time may elapse before commercial production commences. If pipeline facilities
in an area are insufficient, the Company
 
                                       10
<PAGE>
may have to await the construction or expansion of pipeline capacity before
production from that area can be marketed. The Company's domestic offshore
properties are generally located in areas where a pipeline infrastructure is
well developed and there is adequate availability in such pipelines to transport
the Company's current and projected future production.
 
    The Company's Thailand Concession is traversed by two major (34 inches and
36 inches in diameter, respectively) natural gas pipelines that are owned and
operated by PTT and which come within approximately 25 miles of the Tantawan
Field (and are slightly closer to the Benchamas Field). Thaipo and its joint
venture partners in the Tantawan Field signed a long-term gas sales contract
with PTT in November 1995 which has since been amended to include production
from the Benchamas Field. All oil and condensate production from the Tantawan
Field is initially stored aboard the FPSO and is then sold to various third
parties, including PTT, on a tanker load by tanker load basis at prices based on
then current world oil prices, typically with reference to the Malaysian Tapis
crude oil benchmark price. The buyer is responsible for sending a tanker to off
load the oil and condensate it has purchased. It is currently anticipated that
when the Benchamas Field commences production, crude oil and condensate
production from the Benchamas Field will be initially stored aboard the FSO and
a portion of such production will be sold under a long-term contract with a
single buyer and a portion will continue to be sold on a tanker load by tanker
load basis, similar to the way Tantawan Field crude is currently marketed. See
"--International Operations; Contractual Terms Governing the Thailand Concession
and Related Production."
 
    The marketing of onshore oil and gas production is also subject to the
availability of pipelines, crude oil hauling and other transportation,
processing and refining facilities as well as the existence of adequate markets.
Generally, the Company's onshore oil and gas production is located in areas
where commercial production of economic discoveries can be rapidly effectuated.
 
    Most of the Company's North American natural gas sales are currently made in
the "spot market" for no more than one month at a time at then currently
available prices. Prices on the spot market fluctuate with demand. Crude oil and
condensate production is also generally sold one month at a time at the price
that is then currently available. Other than any futures contracts which may
exist from time to time, and which are referred to in "--Miscellaneous;
Competition and Market Conditions," and the Gas Sales Agreement with PTT for
production from the Tantawan and Benchamas Fields (see "--International
Operations; Contractual Terms Governing the Thailand Concession and Related
Production"), the Company has no existing contracts that require the delivery of
fixed quantities of oil or natural gas other than on a best efforts basis. Enron
Corp. and its affiliates and PTT, who purchased $29,539,000 (15% of the
Company's consolidated gross revenues) and $23,137,000 (12% of the Company's
consolidated gross revenues) of the Company's oil and gas production during
1998, respectively, were the Company's only customers to which sales exceeded
10% of its 1998 revenues. The oil and gas sold to Enron Corp. and its affiliates
was sold under a number of short term, generally month to month, contracts.
 
    COMPETITION AND MARKET CONDITIONS
 
    The Company experiences competition from other oil and gas companies in all
phases of its operations, as well as competition from other energy related
industries. The Company's profitability and cash flow are highly dependent upon
the prices of oil and natural gas, which historically have been seasonal,
cyclical and volatile. In general, prices of oil and gas are dependent upon
numerous factors beyond the control of the Company, including various weather,
economic, political and regulatory conditions. In the past, when natural gas
prices in the United States were low, the Company at times elected to curtail
certain quantities of its production. In the future, the Company may again elect
to curtail certain quantities of its natural gas production. Current low oil
prices continue to have a material adverse effect on the Company's cash flows
and, if sustained for a significant length, could have a material adverse effect
on the Company's operations and financial condition and may result in a further
reduction in funds available under the Company's credit agreement.
 
    Because it is impossible to predict future oil and gas price movements with
any certainty, the Company from time to time enters into contracts on a portion
of its production to hedge against the volatility in oil and gas prices. Such
hedging transactions, historically, have never exceeded 50% of the Company's
total oil and gas production on an energy equivalent basis for any given period.
While intended
 
                                       11
<PAGE>
to limit the negative effect of price declines, such transactions could
effectively limit the Company's participation in price increases for the covered
period, which increases could be significant. As of December 31, 1998, the
Company was not a party to any natural gas futures contracts, crude oil swap
agreements or other commodity hedging arrangements. When the Company does engage
in such hedging activities, it may satisfy its obligations with its own
production or by the purchase (or sale) of third party production. The Company
may also cancel all delivery obligations by offsetting such obligations with
equivalent agreements, thereby effecting a purely cash transaction.
 
    OPERATING AND UNINSURED RISKS
 
    The Company's operations are subject to risks inherent in the exploration
for and production of oil and natural gas, such as blowouts, cratering,
explosions, uncontrollable flows of oil, natural gas or well fluids, fires,
pollution and other environmental risks. Offshore oil and gas operations are
subject to the additional hazards of marine and helicopter operations, such as
capsizing, collision and adverse weather and sea conditions. These hazards could
result in substantial losses to the Company due to injury or loss of life,
severe damage to and destruction of property and equipment, pollution and other
environmental damage and suspension of operations. The Company carries insurance
which it believes is in accordance with customary industry practices, but is not
fully insured against all risks incident to its business.
 
    Drilling activities are subject to numerous risks, including the risk that
no commercially productive hydrocarbon reserves will be encountered. The cost of
drilling, completing and operating wells and of installing production facilities
and pipelines is often uncertain. The Company's drilling operations may be
curtailed, delayed or canceled as a result of numerous factors, including title
problems, weather conditions, compliance with governmental requirements and
shortages or delays in the delivery or availability of material, equipment and
fabrication yards. The availability of a ready market for the Company's natural
gas production depends on a number of factors, including the demand for and
supply of natural gas, the proximity of natural gas reserves to pipelines, the
capacity of such pipelines and government regulations.
 
    Due to the recent decline in oil and gas prices, many of the Company's
partners, particularly the smaller ones, are experiencing liquidity and cash
flow problems. These problems may lead to their attempting to delay or slow down
the pace of drilling or project development in order to conserve cash, to a
point that the Company believes is detrimental to the project. In most cases,
the Company has the ability to influence the pace of development through joint
operating agreements. Some partners may be unwilling or unable to pay their
share of the costs of projects as they become due. At worst, a partner may
declare bankruptcy and refuse or be unable to pay its share of the costs of a
project. The Company would then be required to pay this partner's share of the
project costs. In most instances, the Company believes that it is contractually
protected from such an event through its ability to take over the non-paying
partner's share of the project and by applicable oil and gas lien laws and
bankruptcy laws. The Company believes that it would ultimately recover any sums
that it is owed by non-paying partners that do not meet their share of the costs
of a project in a timely fashion.
 
    RISKS OF FOREIGN OPERATIONS
 
    Ownership of property interests and production operations in Thailand and
Canada, and in any other areas outside the United States in which the Company
may choose to do business, are subject to the various risks inherent in foreign
operations. These risks may include, among other things, currency restrictions
and exchange rate fluctuations, loss of revenue, property and equipment as a
result of hazards such as expropriation, nationalization, war, insurrection and
other political risks, risks of increases in taxes and governmental royalties,
renegotiation of contracts with governmental entities, changes in laws and
policies governing operations of foreign-based companies and other uncertainties
arising out of foreign government sovereignty over the Company's international
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Results of Operations; Foreign Currency Transaction Gain
(Loss)," and "--Liquidity and Capital Resources; Other Matters; Southeast Asia
Economic Issues." The Company's international operations may also be adversely
affected by laws and policies of the United States affecting foreign trade,
taxation and investment. In addition, in the event of a dispute arising from
foreign operations, the Company may be subject to the exclusive jurisdiction of
 
                                       12
<PAGE>
foreign courts or may not be successful in subjecting foreign persons to the
jurisdiction of the courts of the United States. The Company seeks to manage
these risks by concentrating its international exploration efforts in areas
where the Company believes that the existing government is stable and favorably
disposed towards United States exploration and production companies.
 
EXPLORATION AND PRODUCTION DATA
 
    In the following data "gross" refers to the total acres or wells in which
the Company has an interest and "net" refers to gross acres or wells multiplied
by the percentage working interest owned by the Company.
 
    ACREAGE
 
    The Company owns interests in developed and undeveloped oil and gas acreage
in various parts of the world. These ownership interests generally take the form
of "working interests" in oil and gas leases which have varying terms. In
addition, the Company holds certain other types of mineral interests, including
fee interests (which never expire) and royalty interests (which generally
terminate when the underlying mineral lease expires). The Company owns varying
fee and royalty interests in 10,800 gross acres in Texas and a royalty interest
in 5,000 gross acres (1,250 net acres) offshore Louisiana. The following table
shows the Company's interest in developed and undeveloped oil and gas acreage
under lease as of December 31, 1998:

(a) ("Developed acreage" consists of lease acres spaced or assignable to
    production (including acreage held by aproduction) on which wells have been
    drilled or completed to a point that would permit production of commercial)
    quantities of oil or natural gas. "Developed acreage" in Thailand includes
    all acreage designated as a production area by the Thai government, which
    currently includes the Tantawan, Maliwan, Benchamas and Pakakrong production
    areas.

PRODUCTIVE WELLS AND DRILLING ACTIVITY
 
    The following table shows the Company's interest in productive oil and
natural gas wells as of December 31, 1998. For purposes of this table
"productive wells" are defined as wells producing hydrocarbons and wells
"capable of production" (e.g., natural gas wells waiting for pipeline
connections or necessary governmental certification to commence deliveries and
oil wells waiting to be connected to currently installed production facilities).
This table does not include exploratory or developmental wells which have
located commercial quantities of oil or natural gas but which are not capable of
commercial production without the installation of material production facilities
or which, for a variety of reasons, the Company does not currently believe will
be placed on production.

(a) One or more completions in the same bore hole are counted as one well. The
    data in the above table includes five gross (.6 net) oil wells and 45 gross
    (20.4 net) natural gas wells with multiple completions.
 
    The following table shows the number of successful gross and net exploratory
and development wells in which the Company has participated and the number of
gross and net wells abandoned as dry holes during the periods indicated. An
onshore well is considered successful upon the installation of permanent
equipment for the production of hydrocarbons or when electric logs run to
evaluate such wells indicate the presence of commercial hydrocarbons and the
Company currently intends to complete such wells. Successful offshore wells
consist of exploratory or development wells that have been completed or are
"suspended" pending completion (which has been determined to be feasible and
economic) and exploratory test wells that were not intended to be completed and
that encountered commercially producible

hydrocarbons. A well is considered a dry hole upon reporting of permanent
abandonment to the appropriate agency.

    amortization associated with property and equipment.
 
(b) The major contributing factor to lifting costs are lease operating expenses.
    A substantial portion of the Company's blease operating expenses in the
    Kingdom of Thailand relate to lease payments made by a subsidiary of the
    Company in connection with its bareboat charter of the FPSO, which amounted
    to $11,122,000 net to the Company during 1998. See "Management's Discussion

(a) The Company believes, for the reasons set forth in succeeding paragraphs,
    that the present value of estimated future anet revenues set forth in the
    Annual Report and calculated in accordance with SEC guidelines are not
    necessarily indicative of the true present value of the Company's reserves
    and, due to the fact that essentially all of the Company's domestic natural
    gas production is currently sold on the spot market, whereas all of the
    Company's Thai natural gas production is sold pursuant to a long-term gas
    sales contract, such estimates of future net revenues from the Company's
    domestic and Thai reserves are, accordingly, not useful for comparative
    purposes. See the discussion on the following pages for the prices used in
    making these calculations.
 
    Natural gas liquids comprised approximately 6% of the Company's total proved
liquids reserves and approximately 11% of the Company's proved developed liquids
reserves as of December 31, 1998. All hydrocarbon liquid reserves are expressed
in standard 42 gallon Bbls. All gas volumes and gas sales are expressed in MMcf
at the pressure and temperature bases of the area where the gas reserves are
located.
 
                                       17
<PAGE>
    Proved reserves of crude oil, condensate, natural gas, and natural gas
liquids are estimated quantities that geological and engineering data
demonstrate with reasonable certainty to be recoverable in the future from known
reservoirs under existing conditions. Reservoirs are considered proved if
economic producibility is supported by actual production or formation tests. In
certain instances, proved reserves are assigned on the basis of a combination of
core analysis and electrical and other type logs which indicate the reservoirs
are analogous to reservoirs in the same field which are producing or have
demonstrated the ability to produce on a formation test. The area of a reservoir
considered proved includes (i) that portion delineated by drilling and defined
by fluid contacts, if any, and (ii) the adjoining portions not yet drilled that
can be reasonably judged as economically productive on the basis of available
geological and engineering data. In the absence of data on fluid contacts, the
lowest known structural occurrence of hydrocarbons controls the lower proved
limit of the reservoir. Proved reserves are estimates of hydrocarbons to be
recovered from a given date forward. They may be revised as hydrocarbons are
produced and additional data becomes available. Proved natural gas reserves are
comprised of non-associated, associated and dissolved gas. An appropriate
reduction in gas reserves has been made for the expected removal of liquids, for
lease and plant fuel and the exclusion of non-hydrocarbon gases if they occur in
significant quantities and are removed prior to sale. Reserves that can be
produced economically through the application of established improved recovery
techniques are included in the proved classification when these qualifications
are met: (i) 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, and (ii) it is reasonably certain the
project will proceed. Improved recovery includes all methods for supplementing
natural reservoir forces and energy, or otherwise increasing ultimate recovery
from a reservoir, including, (i) pressure maintenance, (ii) cycling, and (iii)
secondary recovery in its original sense. Improved recovery also includes the
enhanced recovery methods of thermal, chemical flooding, and the use of miscible
and immiscible displacement fluids. Estimates of proved reserves do not include
crude oil, condensate, natural gas, or natural gas liquids being held in
underground storage. Depending on the status of development, these proved
reserves are further subdivided into:
 
        (i) "developed reserves" which are those proved reserves reasonably
    expected to be recovered through existing wells with existing equipment and
    operating methods, including (a) "developed producing reserves" which are
    those proved developed reserves reasonably expected to be produced from
    existing completion intervals now open for production in existing wells, and
    (b) "developed non-producing reserves" which are those proved developed
    reserves which exist behind casing of existing wells which are reasonably
    expected to be produced through these wells in the predictable future where
    the cost of making such hydrocarbons available for production should be
    relatively small compared to the cost of new wells; and
 
        (ii) "undeveloped reserves" which are those proved reserves reasonably
    expected to be recovered from new wells on undrilled acreage, from existing
    wells where a relatively large expenditure is required and from acreage for
    which an application of fluid injection or other improved recovery technique
    is contemplated where the technique has been proved effective by actual
    tests in the area in the same reservoir. Reserves from undrilled acreage are
    limited to those drilling units offsetting productive units that are
    reasonably certain of production when drilled. Proved reserves for other
    undrilled units are included only where it can be demonstrated with
    reasonable certainty that there is continuity of production from the
    existing productive formation.
 
    In computing future revenues from gas reserves attributable to the Company's
domestic interests, prices in effect at December 31, 1998 were used, including
current market prices, contract prices and fixed and determinable price
escalations where applicable. In accordance with SEC guidelines, the gas prices
that were used make no allowances for seasonal variations in gas prices which
are likely to cause future yearly average gas prices to be somewhat lower than
December gas prices. For domestic gas sold under contract, the contract gas
price including fixed and determinable escalations, exclusive of inflation
adjustments, was used until the contract expires and then was adjusted to the
current market price for the area and held at this adjusted price to depletion
of the reserves. In computing future revenues from liquids attributable to the
Company's domestic interests, prices in effect at December 31, 1998 were used
and
 
                                       18
<PAGE>
these prices were held constant to depletion of the properties. The future
revenues are adjusted to reflect the Company's net revenue interest in these
reserves as well as any ad valorem and other severance taxes but do not include,
unless otherwise noted, any provisions for corporate income taxes.
 
    In computing future revenues from the Company's gas reserves attributable to
the Company's interests in the Kingdom of Thailand, the current contract price
under the Gas Sales Agreement was used, without giving effect to any of the
adjustments provided for in the Gas Sales Agreement, due to their indeterminate
nature as of December 31, 1998, in accordance with SEC guidelines. In computing
future revenues from liquids attributable to the Company's interests in the
Kingdom of Thailand, a price was used which the Company believes approximates
the price that the Company would have received for its production from the
Thailand Concession based upon the world market price for Tapis benchmark crude
on December 31, 1998, and this price was held constant until depletion of the
Company's reserves in the Kingdom of Thailand. The future revenues are adjusted
to reflect the Company's net revenue interest in these reserves and the
Company's obligations under the Thailand Concession, including the payment of
SRB and applicable production bonuses, but does not include any provisions for
U.S. or Thai corporate income or other taxes.
 
    In accordance with SEC guidelines, the prices used by the Company to
calculate the present value of estimated future revenues are determined on a
well or field by field basis, as applicable, as described above and were held
constant over the productive life of the reserves. The initial weighted average
prices used by Ryder Scott were as follows:

    The estimates of future net revenue from the Company's domestic and Thailand
properties are based on existing law where the properties are located and are
calculated in accordance with SEC guidelines. Operating costs for the leases and
wells include only those costs directly applicable to the leases or wells. When
applicable, the operating costs include a portion of general and administrative
costs allocated directly to the leases and wells under terms of operating
agreements. Development costs are based on authorization for expenditure for the
proposed work or actual costs for similar projects. The current operating and
development costs were held constant throughout the life of the properties. For
properties located onshore, the estimates of future net revenues and the present
value thereof do not consider the salvage value of the lease equipment or the
abandonment cost of the lease since both are relatively insignificant and tend
to offset each other. The estimated net cost of abandonment after salvage was
considered for offshore properties where such costs net of salvage are
significant.
 
    No deduction was made for indirect costs such as general and administrative
and overhead expenses, loan repayments, interest expenses, and exploration and
development prepayments. Accumulated gas production imbalances, if any, have
been taken into account.
 
    Production data used to arrive at the estimates set forth above includes
estimated production for the last few months of 1998. The future production
rates from reservoirs now on production may be more or less than estimated
because of, among other reasons, mechanical breakdowns and changes in market
demand or allowables set by regulatory bodies. Properties which are not
currently producing may start producing earlier or later than anticipated in the
estimates of future production rates.
 
                                       19
<PAGE>
    The future prices received by the Company for the sales of its production
may be higher or lower than the prices used in calculating the estimates of
future net revenues and the present value thereof as set forth herein, and the
operating costs and other costs relating to such production may also increase or
decrease from existing levels; however, such possible changes in prices and
costs were, in accordance with rules adopted by the SEC, omitted from
consideration in arriving at such estimates.
 
    There are numerous uncertainties in estimating the quantity of proved
reserves and in projecting the future rates of production and timing of
development expenditures. Oil and gas reserve engineering must be recognized as
a subjective process of estimating underground accumulations of oil and gas that
cannot be measured in an exact way, and estimates of other engineers might
differ materially from those of Ryder Scott, the Company's reserve engineers.
The accuracy of any reserve estimate is a function of the quality of available
data and of engineering and geological interpretation and judgment. Results of
drilling, testing and production subsequent to the date of the estimate may
justify revision of such estimate, which revisions may be material. Accordingly,
reserve estimates are often different from the quantities of oil and gas that
are ultimately recovered.
 
    The Company is periodically required to file estimates of its oil and gas
reserve data with various U.S. governmental regulatory authorities and agencies,
including the Federal Energy Regulatory Commission ("FERC") and the Federal
Trade Commission; with respect to reserves located in Canada, with the Alberta
Energy Utilities Board and, with respect to reserves located in Thailand, the
Kingdom of Thailand's Department of Mineral Resources and PTT, which the Company
considers a quasi-governmental authority. In addition, estimates are from time
to time furnished to governmental agencies in connection with specific matters
pending before such agencies. The basis for reporting reserves to these
agencies, in some cases, is not comparable to that furnished by Ryder Scott in
accordance with SEC guidelines because of the nature of the various reports
required. The major differences generally include differences in the time as of
which such estimates are made, differences in the definition of reserves,
requirements to report in some instances on a gross, net or total operator basis
and requirements to report in terms of smaller geographical units. During 1998,
no estimates by the Company of its total proved net oil and gas reserves were
filed with or included in reports to any governmental authority or agency other
than the SEC; the Alberta Energy Utilities Board for Canadian Reserves; and,
with respect to reserves relating to the Company's properties located in
Thailand, the Kingdom of Thailand's Department of Mineral Resources and PTT.
 
GOVERNMENT REGULATION
 
    The Company's operations are affected from time to time in varying degrees
by political developments and governmental laws and regulations. Rates of
production of oil and gas have for many years been subject to governmental
conservation laws and regulations, and the petroleum industry has been subject
to federal and state tax laws dealing specifically with it.
 
    FEDERAL INCOME TAX
 
    The Company's operations are significantly affected by certain provisions of
the federal income tax laws applicable to the petroleum industry. The principal
provisions affecting the Company are those that permit the Company, subject to
certain limitations, to deduct as incurred, rather than to capitalize and
amortize, its domestic "intangible drilling and development costs" and to claim
depletion on a portion of its domestic oil and gas properties based on 15% of
its oil and gas gross income from such properties (up to an aggregate of 1,000
Bbls per day of domestic crude oil and/or equivalent units of domestic natural
gas) even though the Company has little or no basis in such properties. Under
certain circumstances, however, a portion of such intangible drilling and
development costs and the percentage depletion allowed in excess of basis will
be tax preference items that will be taken into account in computing the
Company's alternative minimum tax.
 
                                       20
<PAGE>
    ENVIRONMENTAL MATTERS
 
    Domestic oil and gas operations are subject to extensive federal regulation
and, with respect to federal leases, to interruption or termination by
governmental authorities on account of environmental and other considerations
including the Comprehensive Environmental Response, Compensation and Liability
Act ("CERCLA") also known as the "Superfund Law." The recent trend towards
stricter standards in environmental legislation and regulation may continue, and
this could increase costs to the Company and others in the industry. Oil and gas
lessees are subject to liability for the costs of clean-up of pollution
resulting from a lessee's operations, and may also be subject to liability for
pollution damages. The Company maintains insurance against costs of clean-up
operations, but is not fully insured against all such risks. A serious incident
of pollution may, as it has in the past, also result in the Department of the
Interior requiring lessees under federal leases to suspend or cease operation in
the affected area.
 
    The operators of the Company's properties have numerous applications pending
before the Environmental Protection Agency (the "EPA") for National Pollution
Discharge Elimination System water discharge permits with respect to offshore
drilling and production operations. The issue generally involved is whether
effluent discharges from each facility or installation comply with the
applicable federal regulations.
 
    The Oil Pollution Act of 1990 (the "OPA") and regulations thereunder impose
a variety of regulations on "responsible parties" related to the prevention of
oil spills and liability for damages resulting from such spills in United States
waters. A "responsible party" includes the owner or operator of a facility or
vessel, or the lessee or permittee of the area in which an offshore facility is
located. The OPA assigns liability to each responsible party for oil removal
costs and a variety of public and private damages. While liability limits apply
in some circumstances, a party cannot take advantage of liability limits if the
spill was caused by gross negligence or willful misconduct or resulted from
violation of a federal safety, construction or operating regulations. If the
party fails to report a spill or cooperate fully in the cleanup, liability
limits likewise do not apply. Few defenses exist to the liability imposed by the
OPA.
 
    The OPA also imposes ongoing requirements on responsible parties, including
proof of financial responsibility to cover at least some costs in a potential
spill. For tank vessels, including mobile offshore drilling rigs, the OPA
imposes on owners, operators and charterers of the vessels, an obligation to
maintain evidence of financial responsibility of up to $10,000,000 depending on
gross tonnage. With respect to offshore facilities, proof of greater levels of
financial responsibility may be applicable. For offshore facilities that have a
worst case oil spill potential of more than 1,000 Bbls (which includes many of
the Company's offshore producing facilities), certain amendments to the OPA that
were enacted in 1996 provide that the amount of financial responsibility that
must be demonstrated for most facilities ranges from $10,000,000 to $35,000,000,
depending upon location, with higher amounts, up to $150,000,000 in certain
limited circumstances. The Company believes that it currently has established
adequate proof of financial responsibility for its offshore facilities at no
significant increase in expense over recent prior years. However, the Company
cannot predict whether these financial responsibility requirements under the OPA
amendments will result in the imposition of substantial additional annual costs
to the Company in the future or otherwise materially adversely affect the
Company. The impact, however, should not be any more adverse to the Company than
it will be to other similarly situated or less capitalized owners or operators
in the Gulf of Mexico.
 
    The Company's onshore operations are subject to numerous United States and
Canadian federal, state, provincial and local laws and regulations controlling
the discharge of materials into the environment or otherwise relating to the
protection of the environment including CERCLA. Such laws and regulations, among
other things, impose absolute liability on the lessee under a lease for the cost
of clean-up of pollution resulting from a lessee's operations, subject the
lessee to liability for pollution damages, may require suspension or cessation
of operations in affected areas, and impose restrictions on the injection of
liquids into subsurface aquifers that may contaminate groundwater. Such laws
could have a significant impact on the operating costs of the Company, as well
as the oil and gas industry in general. Federal, state,
 
                                       21
<PAGE>
provincial and local initiatives to further regulate the disposal of oil and gas
wastes are also pending in certain states and Canadian provinces, and these
initiatives could have a similar impact on the Company.
 
    The Company is asked to comment on the costs it incurred during the prior
year on capital expenditures for environmental control facilities and the amount
it anticipates incurring during the coming year. The Company believes that, in
the course of conducting its oil and gas operations, many of the costs
attributable to environmental control facilities would have been incurred absent
environmental regulations as prudent, safe oilfield practice. During 1998, the
Company incurred capital expenditures of approximately $4,600,000 for
environmental control facilities, primarily relating to the installation of
certain environmental control facilities on four platforms installed in the Gulf
of Thailand and one platform in the Gulf of Mexico, and the drilling of three
salt water disposal wells. The Company budgeted approximately $171,000 for
expenditures involving environmental control facilities during 1999, including,
among other things, environmental control equipment for two platforms in the
Gulf of Thailand.
 
    OTHER LAWS AND REGULATIONS
 
    Various laws and regulations often require permits for drilling wells and
also cover spacing of wells, the prevention of waste of oil and gas including
maintenance of certain gas/oil ratios, rates of production and other matters.
The effect of these laws and regulations, as well as other regulations that
could be promulgated by the jurisdictions in which the Company has production,
could be to limit the number of wells that could be drilled on the Company's
properties and to limit the allowable production from the successful wells
completed on the Company's properties, thereby limiting the Company's revenues.
 
    The Minerals Management Service of the Department of the Interior (the
"MMS") administers the oil and gas leases held by the Company on federal onshore
lands and offshore tracts in the Outer Continental Shelf. The MMS holds a
royalty interest in these federal leases on behalf of the federal government.
While the royalty interest percentage is fixed at the time that the lease is
entered into, from time to time the MMS changes or reinterprets the applicable
regulations governing its royalty interests, and such action can indirectly
affect the actual royalty obligation that the Company is required to pay. In a
letter dated May 3, 1993, the MMS announced a reinterpretation of its right to
collect royalty payments from producers on certain settlements in which such
producers and pipeline companies were involved a number of years ago. The MMS
reinterpretation has been challenged in court by various producers and trade
groups representing them. On August 27, 1996, in INDEPENDENT PETROLEUM
ASSOCIATION OF AMERICA, ET AL. V. BABBIT ET AL., Nos. 95-5210 ETC., the United
States Court of Appeals for the District of Columbia Circuit held that the May
3, 1993, reinterpretation was invalid and unenforceable. Unless and until this
or other similar cases are resolved in favor of the MMS' reinterpretation of its
regulations, it is unlikely that the Company or other producers will be legally
required to pay royalties on such settlement agreements. The Company was
involved in several settlement agreements with pipelines that could be subject
to the MMS' new reinterpretation. The MMS has reviewed the Company's and other
producers' settlement agreements, to determine whether it believes any
additional royalty payments may be due and has asserted that additional
royalties may be due in connection with two of the Company's settlement
agreements. Based upon existing case law, the Company has asserted through the
administrative appeals process, and continues to believe, that it does not owe
any additional royalties beyond what it has previously paid. However, in the
event that the MMS is able to successfully assert that additional royalty is due
from the Company in connection with settlement agreements to which the Company
is a party, the Company does not currently believe that such additional
assessment will have a material adverse impact on the financial position or
results of operations of the Company.
 
    Recently the MMS and various state and municipal authorities have attempted
to collect alleged underpayment of royalties from various integrated oil
companies in connection with sale transactions between exploration and
production affiliates and pipeline affiliates of the same company. The Company
has not been named in any of these collection efforts, a fact that the Company
believes is primarily due to its never having sold any oil or gas production
from one of its affiliates to another. The Company does not believe that it has
any material liability for underpayment of royalty in connection with affiliate
transactions, including those described above.
 
                                       22
<PAGE>
    The FERC has recently embarked on wide-ranging regulatory initiatives
relating to gas transportation rates and services, including the availability of
market-based and other alternative rate mechanisms to pipelines for transmission
and storage services. In addition, the FERC has announced and implemented a
policy allowing pipelines and transportation customers to negotiate rates above
the otherwise applicable maximum lawful cost-based rates on the condition that
the pipelines alternatively offer so-called recourse rates equal to the maximum
lawful cost-based rates. With respect to gathering services, the FERC has issued
orders declaring that certain facilities owned by interstate pipelines primarily
perform a gathering function, and may be transferred to affiliated and
non-affiliated entities that are not subject to the FERC's rate jurisdiction.
These orders have been generally upheld on appeal to the courts. The Company
cannot predict the ultimate outcome of these developments, nor the effect of
these developments on transportation rates. Inasmuch as the rates for these
pipeline services can affect the gas prices received by the Company for the sale
of its production, the FERC's actions may have an impact on the Company.
However, the impact should not be substantially different on the Company than it
will on other similarly situated gas producers and sellers.
 
EMPLOYEES
 
    As of December 31, 1998, the Company and its subsidiaries had 185 full-time

represented by a union for collective bargaining purposes. The Company considers
its relations with its employees to be excellent.

    As of February 22, 1999, there were 3,287 holders of record of the Company's
Common Stock.
 
    In each of 1997 and 1998, the Company paid four quarterly dividends of $0.03
per share on its Common Stock. However, the declaration and payment of future
dividends will depend upon, among other things, the Company's future earnings
and financial condition, liquidity and capital requirements, the general
economic and regulatory climate and other factors deemed relevant by the
Company's Board of Directors.
 
    Pursuant to the Company's revolving credit agreement with its banks under
which the Company has borrowed funds, and the Indentures relating to the
Company's 8 3/4% Senior Subordinated Notes due 2007 (the "2007 Notes") and
10 3/8% Senior Subordinated Notes due 2009 (the "2009 Notes"), the Company may
not, subject to certain exceptions, pay any dividends on its capital stock or
make any other distributions on shares of its capital stock (other than
dividends or distributions payable solely in shares of such capital stock) or
apply any funds, property or assets to the purchase, redemption, sinking fund or
other retirement of its capital stock, if the aggregate amount of all such
dividends, purchases, and redemptions would exceed an amount determined based on
the consolidated income of the Company and its consolidated subsidiaries plus
the proceeds of the issuance of capital stock from and after a specified date
set forth in each respective agreement or, in the case of the revolving credit
agreement, if the net worth of the Company is negative. As of February 1, 1999,
$15,000,000 was available for dividends under this limitation in the Indenture
relating to the 2009 Notes, the agreement currently having the most restrictive
covenants.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS.
 
    On August 17, 1998, a wholly owned subsidiary of the Company merged with and
into Arch Petroleum Inc. ("Arch") in a stock-for-stock tax-free merger accounted
for as a purchase. In connection with the merger, the Company paid off
$51,749,000 of Arch's existing bank debt and production payment obligations. The
Company also exchanged $5,000,000 of Arch's existing convertible subordinated
notes, 727,273 shares of Arch preferred stock (having a liquidation preference
of $20,000,000) and 17,321,804 shares of Arch common stock for approximately
2,500,000 shares of Common Stock.
 
RESULTS OF OPERATIONS
 
    NET INCOME (LOSS)
 
    The Company reported a net loss for 1998 of $43,098,000 or $1.14 per share,
compared to net income for 1997 of $37,116,000 or $1.11 per share ($40,198,000
or $1.06 per share on a diluted basis) and net income for 1996 of $32,760,000 or
$0.99 per share ($35,843,000 or $0.95 per share on a diluted basis). Among other
items affecting the net loss for 1998 were non-recurring expenses totaling
approximately $2,285,000 ($1,485,000 or $0.04 per share on an after-tax basis)
related to the Company's acquisition of Arch and impairments to its oil and gas
properties of $30,813,000, primarily resulting from poor reservoir performance
and persistent low oil and gas prices. The Company recorded an extraordinary
loss of $821,000 during the second quarter of 1996 related to the early
retirement of the Company's 8% Convertible Subordinated Debentures, due 2005
with the proceeds from the Company's issuance on June 18, 1996, of its 5 1/2%
Convertible Subordinated Notes, due 2006 (the "2006 Notes").
 
    Earnings per common share are based on the weighted average number of common
shares outstanding for 1998 of 37,902,000, compared to 33,421,000 (38,064,000 on
a diluted basis) for 1997 and 33,203,000 (37,920,000 on a diluted basis) for
1996. The increase in the weighted average number of common shares outstanding
for 1998, compared to 1997, resulted primarily from the issuance of 3,882,023
shares of its common stock upon the conversion of the Company's 5 1/2%
Convertible Subordinated Notes due 2004 (the "2004 Notes") prior to their being
redeemed on March 16, 1998, the issuance as of August 17, 1998 of approximately
2,500,000 shares of common stock to former holders of Arch capital stock and
convertible debt securities in connection with the Company's acquisition of Arch
and, to a lesser extent, the issuance of common stock upon the exercise of stock
options pursuant to the Company's stock option plans. The increase in weighted
average number of common shares outstanding for 1997, compared to 1996, resulted
primarily from the issuance of common stock upon the exercise of stock options
pursuant to the Company's stock option plans. The earnings per share computation
on a diluted basis in 1998 is identical to the basic earnings per share
computation because there were no securities of the Company that were dilutive
during the period. The earnings per share computation on a diluted basis in 1997
and 1996 primarily reflect additional shares of common stock issuable upon the
assumed conversion of the 2004 Notes and the elimination of related interest
requirements, as adjusted for applicable federal income taxes and, to a lesser
extent, the assumed exercise of options to purchase common shares. In addition,
the number of common shares outstanding in the diluted computation is adjusted,
in accordance with the Financial Accounting Standards Board's Statement of
Financial Accounting Standards ("SFAS") No. 128, to include dilutive shares that
are assumed to have been issued by the Company in connection with options
exercised during the year, less treasury shares that are assumed to have been
purchased by the Company from the option proceeds. SFAS No. 128 was adopted by
the Company in 1997, resulting in a restatement of the earnings per share
calculations for 1997 and 1996, and all preceding years.
 
    TOTAL REVENUES
 
    The Company's total revenues for 1998 were $202,803,000, a decrease of
approximately 29% from total revenues of $286,300,000 for 1997, and a decrease
of approximately 1% from total revenues of $203,977,000 for 1996. The decrease
in the Company's total revenues for 1998, compared to 1997, resulted primarily
from the substantial decrease in oil and gas revenues, that was partially offset
by an increase in pipeline sales related to the Saginaw pipeline, which was
acquired as part of the Arch acquisition, in the
 
                                       27
<PAGE>
third quarter of 1998. The decrease in the Company's total revenues for 1998,
compared to 1996, resulted primarily from the decrease in oil and gas revenues
that were nearly offset by the revenues generated by the Saginaw pipeline.
 
    OIL AND GAS REVENUES
 
    The Company's oil and gas revenues for 1998 were $200,154,000, a decrease of
approximately 30% from oil and gas revenues of $284,851,000 for 1997, and a
decrease of approximately 2% from oil and gas revenues of $203,364,000 for 1996.
The following table reflects an analysis of variances in the Company's oil and
gas revenues (expressed in thousands) between 1998 and the previous two years:

    The decrease in the Company's oil and gas revenues in 1998, compared to
1997, is related to declines in the average price that the Company received for
its natural gas and oil, condensate and NGL ("liquid hydrocarbons") production
volumes and, to a lesser extent, declines in such production volumes. The
decrease in the Company's oil and gas revenues in 1998, compared to 1996, is
related to declines in the average price that the Company received for its
natural gas and liquid hydrocarbon production volumes, that more than offset
substantial increases in natural gas and liquid hydrocarbon production volumes.

(a) Production from the Tantawan Field commenced in February 1997, with a
    start-up phase which extended through March 15, 1997. Consequently, no
    production figures are presented for 1996 and all Thailand production
    figures for 1997 reflect only nine and a half months of full production.
 
    NATURAL GAS
 
    THAILAND PRICES.  The price that the Company receives under the Gas Sales
Agreement for its natural gas production from the Thailand Concession normally
adjusts on a semi-annual basis. However, the Gas Sales Agreement provides for
adjustment on a more frequent basis in the event that certain indices and
factors on which the price is based fluctuate outside a given range. See
"Business--International Operations; Contractual Terms Governing the Thailand
Concession and Related Production." Due to the volatility of the Thai baht and
the current economic difficulties in the Kingdom of Thailand and throughout
Southeast Asia, the price that the Company receives under the Gas Sales
Agreement adjusted several times during 1998, and almost monthly in the latter
half of 1997. The Company cannot predict what the baht to dollar exchange rate
may be in the future. Moreover, it is anticipated that this exchange rate will
remain volatile. See ";Foreign Currency Transaction Gain (Loss)," "--Liquidity
and Capital Resources; Other Matters; Southeast Asia Economic Issues" and
"Business--International Operations; Contractual Terms Governing the Thailand
Concession."
 
                                       29
<PAGE>
    PRODUCTION.  The decrease in the Company's natural gas production during
1998, compared to 1997, was related in large measure to decreased production
from the Company's East Cameron Block 334 "E" platform, and to a lesser extent,
four periods in the second half of 1998 during which most of the Company's
offshore production was shut-in as a precautionary measure due to hurricanes in
the Gulf of Mexico and natural production declines, that was partially offset by
increased production from the Company's onshore properties located in South
Texas and South Louisiana. The increase in the Company's average natural gas
production for 1998, compared to 1996, was related in large measure to the
commencement of production from the Tantawan Field in the first quarter of 1997,
and, to a lesser extent, production from the Company's East Cameron Block 334
"E" platform, which commenced production in April 1997, and production from
properties that the Company acquired in its acquisition of Arch, that was only
partially offset by the anticipated natural decline in deliverability from
certain of the Company's properties. Commencing on October 1, 1998, the Company
and its joint venture partners in the Thailand Concession have been delivering
less natural gas than is being nominated by PTT under the Gas Sales Agreement.
This could result in the Company receiving only 75% of the current contract
price on a portion of its future natural gas sales to PTT. The Company is taking
actions that it currently believes will minimize the penalty that it will incur
on future gas sales to PTT by, among other things, increasing production from
the Tantawan Field. As of December 31, 1998, the Company was not a party to any
future natural gas sales contracts.
 
    CRUDE OIL AND CONDENSATE
 
    THAILAND PRICES.  Since the inception of production from the Tantawan Field,
crude oil and condensate has been stored on the FPSO until an economic quantity
was accumulated for offloading and sale. The first such sale of crude oil and
condensate from the Tantawan Field occurred in July 1997. Prices that the
Company receives for its crude oil and condensate production from Thailand are
based on world benchmark prices, which are denominated in dollars. In addition,
the Company is generally paid for its crude oil and condensate production from
Thailand in U.S. dollars.
 
    PRODUCTION.  The decrease in the Company's crude oil and condensate
production during 1998, compared to 1997, resulted primarily from a decrease in
condensate production from the Company's East Cameron Block 334 "E" platform,
which was in part due to damage sustained in a marine accident at the crude oil
and condensate pipeline from the platform, that was only partially offset by
increased production from a full year's worth of production from the Tantawan
Field and the Company's ongoing development drilling and workover programs in
the offshore and onshore Gulf of Mexico regions. The increase in the Company's
average crude oil and condensate production for 1998, compared to 1996, was
related in large measure to the commencement of production from the Tantawan
Field in the first quarter of 1997 and, to a lesser extent, condensate
production from the Company's East Cameron Block 334 "E" platform, which
commenced production in April 1997 and production from properties that the
Company acquired in its acquisition of Arch, that was only partially offset by
the anticipated natural decline in deliverability from certain of the Company's
properties. As of December 31, 1998, the Company was not a party to any crude
oil swaps or futures contracts.
 
    NGL PRODUCTION.  The Company's oil and gas revenues, and its total liquid
hydrocarbon production, reflect the production and sale by the Company of NGL,
which are liquid products that are extracted from natural gas production. The
decrease in NGL revenues for 1998, compared with 1997, primarily related to a
decrease in the average price that the Company received for its NGL and, to a
lesser extent, a decrease in the Company's NGL production volumes. The decrease
in NGL revenues in 1998, compared with 1996, primarily related to a decrease in
price that the Company received for its NGL production, that was only partially
offset by an increase in the Company's NGL production.

- ------------------------
 
    (a) Production from the Tantawan Field commenced in February 1997, with a
       start-up phase which extended through March 15, 1997. No lease operating
       expenses were incurred in Thailand prior to commencement of production.
 
    LEASE OPERATING EXPENSES.
 
    The increase in North American lease operating expenses for 1998, compared
to 1997, were affected by $2,142,000 in expenses related to purchasing natural
gas for transportation and subsequent resale on the Saginaw pipeline system
acquired in the merger with Arch, a non-recurring maintenance project on the
Company's East Cameron 334 "E" platform during the first quarter of 1998 and by
operating expenses related to the Saginaw pipeline system and other Arch
properties for which no corresponding expenses were recorded during 1997. In
addition, lease operating expenses for 1997 were reduced by a $1,793,000 in
refunds in connection with the Company's audit of a joint venture partner and
settlement of a dispute with a vendor. The increase in lease operating expenses
in the Kingdom of Thailand for 1998, compared to 1997, was primarily related to
the fact that prior to the commencement of production in the Tantawan Field on
February 1, 1997, no lease operating expenses were incurred by the Company in
Thailand. A substantial portion of the Company's lease operating expenses in the
Kingdom of Thailand relate to lease payments made by Tantawan Services, L.L.C.,
in connection with its bareboat charter of the FPSO, which amounted to
$11,122,000 and $10,200,000 (net to the Company's interest) for 1998 and 1997,
respectively. See "--Liquidity and Capital Resources; Capital Requirements;
Other Material Long-Term Commitments." In addition to the reasons discussed
above, North American lease operating expenses for 1998, compared to 1996, also
increased due to a shortage of qualified offshore service contractors, which
permitted such contractors to increase the costs of their services significantly
during 1997, increased expenses related to the leasing of certain equipment in
the Gulf of Mexico, a year to year increase in the level of the Company's
operating activities, including increased operating costs related to additional
properties brought on production and an increased ownership interest in certain
properties as a result of the acquisition of such interests also contributed to
the increase.

<PAGE>
    GENERAL AND ADMINISTRATIVE EXPENSES
 
    The increase in general and administrative expenses for 1998, compared with
1997 and 1996, was related to a number of non-recurring expenses arising in
connection with the Company's acquisition of Arch totaling approximately
$2,285,000, that included severance payments to former officers and employees of
Arch, as well as an increase in the size of the Company's work force and normal
salary and concomitant benefit expense adjustments.
 
    EXPLORATION EXPENSES
 
    Exploration expenses consist primarily of rental payments required under oil
and gas leases to hold non-producing properties ("delay rentals") and geological
and geophysical costs which are expensed as incurred. The decreases in
exploration expenses for 1998, compared to 1997 and 1996, resulted primarily
from decreased geophysical activity by the Company in most of its operational
areas except Canada, where the Company participated in a significant 3-D survey
during 1998, and a decrease in delay rental payments.
 
    DRY HOLE AND IMPAIRMENT EXPENSES
 
    Dry hole and impairment expenses relate to costs of unsuccessful wells
drilled, along with impairments resulting from the application of SFAS No. 121
due to decreases in expected reserves from producing wells. The increase in dry
hole and impairment expenses for 1998, compared with 1997 and 1996, was
principally related to the dry hole cost of the Company's Mustang Island Block
A-51 well, and impairment expenses related a decline in reserves at the
Company's East Cameron Block 334/335 Field and its Keystone Field located in
Winkler County, Texas (which the Company sold at year-end 1998) and
disappointing reservoir performance at the Company's South Pass Block 78 Field.
 
    DEPRECIATION, DEPLETION AND AMORTIZATION EXPENSES
 
    The Company accounts for its oil and gas activities using the successful
efforts method of accounting. Under the successful efforts method, lease
acquisition costs and all development costs are capitalized. Proved properties
are reviewed whenever events or changes in circumstances indicate that the value
of such property on the Company's books may not be recoverable. Unproved
properties are reviewed quarterly to determine if there has been impairment of
the carrying value, with any such impairment charged to expense in the period.
Proved oil and gas properties are reviewed when circumstances suggest the need
for such a review and, if required, he proved properties are written down to
their estimated fair value. Estimated fair value includes the estimated present
value of all reasonably expected future production, prices, and costs. As a
result of poor reservoir performance and persistent low oil and gas prices, the
Company performed such a review in 1998 and expensed $30,813,000 related to its
domestic oil and gas properties which is included in the Consolidated Statements
of Income as dry hole and impairment expense. Exploratory drilling costs are
capitalized until the results are determined. If proved reserves are not
discovered, the exploratory drilling costs are expensed. Other exploratory costs
are expensed as incurred.
 
    The provision for DD&A expense is based on the capitalized costs, as
determined in the preceding paragraph, plus future costs to abandon offshore
wells and platforms, and is determined on a cost center by cost center basis
using the units of production method. The Company generally creates cost centers
on a field by field basis for oil and gas activities in the Gulf of Mexico and
Gulf of Thailand. Generally, the Company establishes cost centers on the basis
of an oil or gas trend or play for its oil and gas activities onshore in the
United States and Canada. The increase in the Company's DD&A expenses for 1998,
compared to 1997, resulted primarily from an increase in the Company's composite
rate, that was not entirely offset by a decline in the Company's natural gas and
liquid hydrocarbon production. The increase in the Company's DD&A expenses for
1998, compared to 1996, resulted primarily from an increase in the Company's
natural gas and liquid hydrocarbon production and, to a lesser extent, an
increase in the Company's composite DD&A rate.
 
                                       32
<PAGE>
    The increase in the composite DD&A rate for all of the Company's producing
fields for 1998, compared to 1997 and 1996, resulted primarily from an increased
percentage of the Company's production coming from certain of the Company's
fields that have DD&A rates that are higher than the Company's recent historical
composite rate and a corresponding decrease in the percentage of the Company's
production coming from fields that have DD&A rates that are lower than the
Company's recent historical composite DD&A rate. Management currently
anticipates that this trend will continue for the foreseeable future, resulting
in generally increasing DD&A rates.
 
    INTEREST
 
    INTEREST CHARGES.  The increase in the Company's interest charges for 1998,
compared to 1997 and 1996, resulted primarily from an increase in the average
amount of the Company's outstanding debt and, to a lesser extent, increased
average interest rates on the debt outstanding (resulting primarily from the
issuance of the 2007 Notes on May 22, 1997, which bear interest at an 8 3/4%
annual interest rate). As of December 31, 1998, the Company was not a party to
any interest rate swap agreements. Management currently expects the average
interest rate on its outstanding debt to continue to increase due to the
issuance of the 2009 Notes on January 15, 1999, which bear interest at a 10 3/8%
interest rate.
 
    CAPITALIZED INTEREST.  The increase in capitalized interest for 1998,
compared to 1997 and 1996, resulted primarily from an increase in the amount of
capital expenditures subject to interest capitalization during 1998
($137,956,000) compared to 1997 ($96,530,000) and 1996 ($68,740,000), and from
an increase in the computed rate that the Company uses to apply on such capital
expenditures to arrive at the total amount of capitalized interest. A
substantial percentage of the Company's capitalized interest expense during the
latter half of 1997 and 1998 resulted from capitalization of interest related to
capital expenditures for the development of the Benchamas Field in the Gulf of
Thailand and, to a lesser extent, several development projects in the Gulf of
Mexico.
 
    FOREIGN CURRENCY TRANSACTION GAIN (LOSS)
 
    The foreign currency transaction gain and loss each resulted primarily from
the fluctuation against the U.S. dollar of cash and other monetary assets and
liabilities denominated in Thai baht that were on the Company's subsidiary's
financial statements during the respective periods. In early July 1997, the
government of the Kingdom of Thailand announced that the value of the baht would
be set against the dollar and other currencies under a "managed float" program
arrangement. This led to a substantial decline in value of the Thai baht
compared to the U.S. dollar, resulting in the foreign currency transaction
losses during 1997. During 1998, the value of the Thai baht has generally
strengthened against the U.S. dollar, resulting in corresponding foreign
currency transaction gains. However, the Company cannot predict what the Thai
baht to dollar exchange rate may be in the future. Moreover, it is anticipated
that this exchange rate will remain volatile. As of December 31, 1998, the
Company was not a party to any financial instrument that was intended to
constitute a foreign currency hedging arrangement.
 
    INCOME TAX BENEFIT (EXPENSE)
 
    The Company's income tax benefit for 1998, compared to its income tax
expenses for 1997 and 1996, resulted primarily from a pre-tax loss resulting
from substantially lower revenues in the United States and the tax benefit of
accrued foreign losses from the Company's operations in the Kingdom of Thailand.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    CASH FLOWS
 
    The Company's Consolidated Statement of Cash Flows for 1998 reflects net
cash provided by operating activities of $70,929,000. In addition to net cash
provided by operating activities, the Company received net proceeds of
$1,034,000 from the exercise of stock options, $7,164,000 from the sale of
certain non-strategic properties and tubular stock, and had net borrowings of
$136,447,000 under its Credit
 
                                       33
<PAGE>
Agreement and other senior debt facilities. In addition, on January 15, 1999,
the Company consummated the offering of $150,000,000 of its 2009 Notes.
 
    During 1998, the Company invested $201,946,000 of such cash flow in capital
projects, retired a production payment obligation for $15,246,000 related to the
Arch acquisition, spent $2,961,000 to purchase proved reserves, paid $4,531,000
($0.03 per share for each quarter of 1998) in cash dividends to holders of the
Company's common stock, paid $2,635,000 in debt issuance expenses and paid a net
amount of $621,000 in miscellaneous other expenditures. As of December 31, 1998,
the Company's cash and cash investments were $7,959,000 and its long-term debt
stood at $434,947,000.
 
    FUTURE CAPITAL REQUIREMENTS
 
    The Company's capital and exploration budget for 1999, which does not
include any amounts that may be expended for the purchase of proved reserves or
any interest which may be capitalized resulting from projects in progress, was
established by the Company's Board of Directors at $170,000,000. The Company
currently anticipates that its available cash and cash investments, cash
provided by operating activities, funds available under its Credit Agreement and
uncommitted credit lines and amounts that the Company currently believes that it
can obtain from external sources including the issuance of new debt and
convertible preferred securities, or asset sales, will be sufficient to fund the
Company's ongoing operating, interest and general and administrative expenses,
any currently anticipated costs associated with the Company's projects during
1999, and future dividend payments at current levels (including a dividend
payment of $0.03 per share to be paid on February 26, 1999 to shareholders of
record on February 12, 1999). Subject to favorable market conditions and other
factors, the Company also currently intends to issue convertible preferred
equity securities during 1999 to assist in funding its future capital and
exploration plans. The declaration of future dividends on the Company's common
stock will depend upon, among other things, the Company's future earnings and
financial condition, liquidity and capital requirements, its ability to pay
dividends under certain covenants contained in its debt instruments, the general
economic and regulatory climate and other factors deemed relevant by the
Company's Board of Directors.
 
    OTHER MATERIAL LONG-TERM COMMITMENTS
 
    As of February 9, 1996, Tantawan Services, L.L.C. ("TS"), a company that is
currently a wholly owned subsidiary of the Company, entered into a Bareboat
Charter Agreement (the "Charter") with Tantawan Production B.V. for the charter
of the FPSO for use in the Tantawan Field. See "Business--International
Operations." The term of the Charter is for a period ending July 31, 2008,
subject to extension. In addition, TS has a purchase option on the FPSO
throughout the term of the Charter. TS has also contracted with another company,
SBM Marine Services Thailand Ltd., to operate the FPSO on a reimbursable basis
throughout the initial term of the Charter. Performance of both the Charter and
the agreement to operate the FPSO are non-recourse to TS and the Company.
However, performance is secured by a negative pledge on any hydrocarbons stored
on the FPSO and is guaranteed by each of the working interest holders in the
Tantawan Field, including Thaipo. Thaipo's guarantee is limited to its
percentage interest in the Tantawan Field (currently 46.34%). The Charter
currently provides for an estimated charter hire commitment of $24,000,000 per
year ($11,122,000 net to Thaipo) for the first ten years and a decreasing amount
thereafter.
 
    As of August 24, 1998, Thaipo and its joint venture partners (collectively,
the "Charterers") entered into a Bareboat Charter Agreement (the "BCA") with
Watertight Shipping B.V. for the charter of the FSO. See
"Business--International Operations." The term of the BCA is for a period of ten
years commencing on the date that the FSO is ready to begin operations in the
Benchamas Field. In addition, the Charterers have a purchase option on the FSO
throughout the term of the BCA. The Charterers have also contracted with another
company, Tanker Pacific (Thailand) Co. Ltd, to operate the FSO on a fixed fee
basis throughout the initial term of the BCA. Performance of both the BCA and
the agreement to operate the FSO are non-recourse to the Company. However the
obligations of each joint venturer are full recourse to each joint venturer, but
the obligations are several, meaning that each joint venturer's obligations are
limited to its percentage interest in the Thailand Concession. Collectively, the
BCA and the operating
 
                                       34
<PAGE>
agreement currently provide for an estimated expense of chartering and operating
the FSO of $11,253,000 per year ($5,215,000 net to Thaipo), which will commence
after the FSO is installed in the Benchamas Field in late May or June of this
year.
 
    CAPITAL STRUCTURE
 
    CREDIT AGREEMENT AND UNCOMMITTED CREDIT LINES. Effective August 1, 1997, the
Company entered into an amended and restated Credit Agreement, which was amended
most recently on December 21, 1998. The Credit Agreement provides for a
$200,000,000 revolving/term credit facility which will be fully revolving until
July 1, 2000, after which the balance will be due in eight quarterly term loan
installments, commencing October 31, 2000. The amount that may be borrowed under
the Credit Agreement may not exceed a borrowing base which is composed of
domestic, Canadian and Thai properties. Generally, the borrowing base is
determined semi-annually by the lenders in accordance with the Credit Agreement,
based on the lenders' usual and customary criteria for oil and gas transactions.
As of February 1, 1999, the Company's total borrowing base was set at
$140,000,000, which amount cannot be reduced until after April 30, 1999.
However, due to limitations on total indebtedness under the Credit Agreement,
the Company is currently limited to borrowing only $135,000,000 under the Credit
Agreement and its other senior debt arrangements. The Credit Agreement is
governed by various financial and other covenants, including requirements to
maintain positive working capital (excluding current maturities of debt) and a
fixed charge coverage ratio, and limitations on indebtedness (including a total
indebtedness limit of $500,000,000), creation of liens, the prepayment of
subordinated debt, the payment of dividends, mergers and consolidations,
investments and asset dispositions. In addition, the Company is prohibited from
pledging borrowing base properties as security for other debt. Borrowings under
the Credit Agreement bear interest at a rate based upon the percentage of the
borrowing base that is being utilized, ranging from a base (prime) rate or LIBOR
plus 1.25% to a base rate plus 0.25% or LIBOR plus 2.0%, at the Company's
option. Borrowings under the Credit Agreement currently bear interest at a base
rate or LIBOR plus 1.75%, at the Company's option. A commitment fee on the
unborrowed amount under the Credit Agreement is also charged and is based upon
the percentage of the borrowing base that is being utilized, ranging from 0.25%
to 0.375%. The commitment fee is currently 0.375% per annum on the unborrowed
amount under the Credit Agreement. As of February 15, 1999, there was
$102,000,000 outstanding under the Credit Agreement.
 
    As of February 15, 1999, the Company is a party to separate letter
agreements with two banks under which each bank may provide an uncommitted money
market line of credit. One of the agreements provides for a $20,000,000 line of
credit, and the other provides for a $10,000,000 line of credit. Both lines of
credit are on an as available or as offered basis and neither bank has any
obligation to make any advances under its line of credit. Although loans made
under each letter agreement are for a maximum term of 30 days, they are
reflected as long-term debt on the Company's balance sheet because the Company
currently has the ability and intent to reborrow such amounts under its Credit
Agreement. Each letter agreement permits either party to terminate such letter
agreement at any time. Under its Credit Agreement, the Company is currently
limited to incurring a maximum of $20,000,000 of additional senior debt, which
would include debt incurred under both lines of credit and under the banker's
acceptances discussed below. Further, the 2007 Notes and the 2009 Notes also
restrict the incurrence of additional senior indebtedness. See "; 2007 Notes"
and "; 2009 Notes." As of December 31, 1998, there was $4,000,000 outstanding
under one of the lines of credit at an interest rate of 6.1%
 
    BANKER'S ACCEPTANCES.  On June 3, 1998, the Company entered into a Master
Banker's Acceptance Agreement under which one of the Company's lenders has
offered to accept up to $20,000,000 in bank drafts from the Company. The
banker's drafts are available on an uncommitted basis and the bank has no
obligation to accept the Company's request for drafts. Drafts drawn under this
agreement are for a maximum term of 182 days; however, they are reflected as
long-term debt on the Company's balance sheet because the Company currently has
the ability and intent to reborrow such amounts under the Credit Agreement.
Under its Credit Agreement, the Company is currently limited to incurring a
maximum of $20,000,000 of additional senior debt, which would include banker's
acceptances as well as debt incurred
 
                                       35
<PAGE>
under the lines of credit discussed previously. Further, the 2007 Notes and the
2009 Notes offered also restrict the incurrence of additional senior
indebtedness. See "; 2007 Notes" and "; 2009 Notes." The Master Banker's
Acceptance Agreement permits either party to terminate the letter agreement at
any time upon five business days notice. As of December 31, 1998, bank drafts in
the principal amount of $10,947,000 bearing interest at an average rate of 5.9%
were outstanding under this agreement.
 
    2009 NOTES.  On January 15, 1999, the Company issued $150,000,000 principal
amount of 2009 Notes. The proceeds from the issuance of the 2009 Notes were used
to repay amounts outstanding under the Credit Agreement. The 2009 Notes bear
interest at a rate of 10 3/8%, payable semi-annually in arrears on February 15
and August 15 of each year, commencing August 15, 1999. The 2009 Notes are
general unsecured senior subordinated obligations of the Company, are
subordinated in right of payment to the Company's senior indebtedness, which
currently includes the Company's obligations under the Credit Agreement, its
unsecured credit lines and its banker's acceptances, are equal in right of
payment to the 2007 Notes, but are senior in right of payment to the Company's
subordinated indebtedness, which currently includes the 2006 Notes. The Company,
at its option, may redeem the 2009 Notes in whole or in part, at any time on or
after February 15, 2004, at a redemption price of 105.188% of their principal
value and decreasing percentages thereafter. No sinking fund payments are
required on the 2009 Notes. The 2009 Notes are redeemable at the option of any
holder, upon the occurrence of a change of control (as defined in the indenture
governing the 2009 Notes), at 101% of their principal amount. The indenture
governing the 2009 Notes also imposes certain covenants on the Company that are
substantially identical to the covenants contained in the indenture governing
the 2007 Notes, including covenants limiting: incurrence of indebtedness
including senior indebtedness; restricted payments; the issuance and sales of
restricted subsidiary capital stock; transactions with affiliates; liens;
disposition of proceeds of asset sales; non-guarantor restricted subsidiaries;
dividends and other payment restrictions affecting restricted subsidiaries; and
mergers, consolidations and the sale of assets.
 
    2007 NOTES.  On May 22, 1997, the Company issued $100,000,000 principal
amount of 2007 Notes. The 2007 Notes bear interest at a rate of 8 3/4%, payable
semi-annually in arrears on May 15 and November 15 of each year. The 2007 Notes
are general unsecured senior subordinated obligations of the Company, are
subordinated in right of payment to the Company's senior indebtedness, which
currently includes the Company's obligations under the Credit Agreement, its
unsecured credit lines and its banker's acceptances, are equal in right of
payment to the 2009 Notes, but are senior in right of payment to the Company's
subordinated indebtedness, which currently includes the 2006 Notes. The Company,
at its option, may redeem the 2007 Notes in whole or in part, at any time on or
after May 15, 2002, at a redemption price of 104.375% of their principal value
and decreasing percentages thereafter. No sinking fund payments are required on
the 2007 Notes. The 2007 Notes are redeemable at the option of any holder, upon
the occurrence of a change of control (as defined in the indenture governing the
2007 Notes), at 101% of their principal amount. The indenture governing the 2007
Notes also imposes certain covenants on the Company that are substantially
identical to the covenants contained in the indenture governing the 2009 Notes,
including covenants limiting: incurrence of indebtedness including senior
indebtedness; restricted payments; the issuance and sales of restricted
subsidiary capital stock; transactions with affiliates; liens; disposition of
proceeds of asset sales; non-guarantor restricted subsidiaries; dividends and
other payment restrictions affecting restricted subsidiaries; and mergers,
consolidations and the sale of assets.
 
    2006 NOTES.  The outstanding principal amount of 2006 Notes was $115,000,000
as of December 31, 1998. The 2006 Notes are convertible into Common Stock at
$42.185 per share, subject to adjustment upon the occurrence of certain events.
The 2006 Notes bear interest at a rate of 5 1/2% and will be redeemable at the
option of the Company, in whole or in part, at any time on or after June 15,
1999, at a redemption price of 103.85% of their principal amount and decreasing
percentages thereafter. No sinking fund payments are required on the 2006 Notes.
The 2006 Notes are redeemable at the option of any holder, upon the occurrence
of a repurchase event (a change of control and other circumstances as defined in
the indenture governing the 2006 Notes), at 100% of the principal amount.

    2004 NOTES.  The Company's 2004 Notes were called for redemption on March
16, 1998, at a price equal to 103.30% of their principal amount. Prior thereto,
holders of all but $95,000 principal amount of the 2004 Notes chose to convert
their 2004 Notes into Common Stock at a conversion price of $22.188 per common
share, rather than receive cash for their 2004 Notes resulting in the issuance
of 3,879,726 shares of Common Stock.
 
    OTHER MATTERS
 
    INFLATION.  Publicly held companies are asked to comment on the effects of
inflation on their business. Currently annual inflation in terms of the decrease
in the general purchasing power of the U.S. dollar is running much below the
general annual inflation rates experienced in the past. While the Company, like
other companies, continues to be affected by fluctuations in the purchasing
power of the U.S. dollar due to inflation, such effect is not currently
considered significant.
 
    SOUTHEAST ASIA ECONOMIC ISSUES.  A substantial portion of the Company's oil
and gas operations are conducted in Southeast Asia, and a substantial portion of
its natural gas and liquid hydrocarbon production is sold there. Southeast Asia
in general, and the Kingdom of Thailand in particular, have experienced severe
economic difficulties which have been characterized by sharply reduced economic
activity, illiquidity, highly volatile foreign currency exchange rates and
unstable stock markets. The government of the Kingdom of Thailand and other
governments in the region are currently acting to address these issues. However,
the economic difficulties currently being experienced in Thailand, together with
the volatility of the Thai baht against the U.S. dollar, will continue to have a
material impact on the Company's operations in the Kingdom of Thailand, together
with the prices that the company receives for its oil and natural gas production
there. See "--Results of Operations; Oil and Gas Revenues" and "--Results of
Operations; Foreign Currency Transaction Gain (Loss)."
 
    All of the Company's current natural gas production from the Thailand
Concession is committed under a long-term Gas Sales Agreement to PTT at a price
denominated in Thai baht which is determined in accordance with a formula that
is intended to ameliorate, at least in part, any decline in the purchasing power
of the Thai baht against the U.S. dollar. See "Business--International
Operations; Contractual Terms Governing the Thailand Concession" and
"Business--Miscellaneous; Sales." Although the Company currently believes that
PTT will honor its commitments under the Gas Sales Agreement, a failure by PTT
to honor such commitments could have a material adverse effect on the Company.
 
    The Company's crude oil and condensate production from the Thailand
Concession is currently sold on a tanker load by tanker load basis. Prices that
the Company receives for such production are based on world benchmark prices,
which are denominated in U.S. dollars, and are typically paid in U.S. dollars.
See "Business--International Operations; Contractual Terms Governing the
Thailand Concession and Related Production" and "Business--Miscellaneous;
Sales." The Company believes that the current economic difficulties in Southeast
Asia have resulted in a decreased demand for petroleum products in the region,
which has contributed to the recent general decline in crude oil and condensate
prices throughout the world. This price decline has had an adverse effect on all
oil and gas companies that sell their production on the world spot markets,
including the Company, without regard to where their respective production is
located.
 
    YEAR 2000 READINESS DISCLOSURE.  Many computer software systems, as well as
certain hardware and equipment using date-sensitive data, were structured to use
a two-digit date field meaning that they may not be able to properly recognize
dates in the year 2000. The Company is addressing this issue through a process
that entails evaluation of the Company's critical software and, to the extent
possible, its hardware and equipment to identify and assess Year 2000 issues and
to remediate, replace or establish alternative procedures addressing non-Year
2000 compliant systems, hardware and equipment.
 
    The Company has substantially completed an inventory of its systems and
equipment including computer systems and business applications. Based upon this
review, the Company currently believes that all of its critical software and
computer hardware systems are either Year 2000 compliant or will be within the
next six months. The Company continues to inventory its equipment and facilities
to determine if they
 
                                       37
<PAGE>
contain embedded date-sensitive technology. If problems are discovered,
remediation, replacement or alternative procedures for non-compliant equipment
and facilities will be undertaken on a business priority basis. This process
will continue and, depending upon the equipment and facilities, is scheduled for
completion during the first three quarters of 1999. As of December 31, 1998, the
Company had incurred approximately $50,000 in expenses related to its Year 2000
compliance efforts. These costs are currently being expensed as they are
incurred. However, in certain instances the Company may determine that replacing
existing equipment may be more efficient, particularly where additional
functionality is available. These replacements may be capitalized and therefore
would reduce the estimated 1999 expenses associated with the Year 2000 issue.
The Company currently expects total out-of-pocket costs to become Year 2000
compliant to be less than $1,000,000. The Company currently expects that such
costs will not have a material adverse effect on the Company's financial
condition, operations or liquidity.
 
    The foregoing timetable and assessment of costs to become Year 2000
compliant reflect management's current best estimates. These estimates are based
on many assumptions, including assumptions about the cost, availability and
ability of resources to locate, remediate and modify affected systems, equipment
and facilities. Based upon its activities to date, the Company does not
currently believe that these factors will cause results to differ significantly
from those estimated. However, the Company cannot reasonably estimate the
potential impact on its financial condition and operations if key third parties
including, among others, suppliers, contractors, joint venture partners,
financial institutions, customers and governments do not become Year 2000
compliant on a timely basis. The Company is contacting many of these third
parties to determine whether they will be able to resolve in a timely fashion
their Year 2000 issues as they may affect the Company.
 
    In the event that the Company is unable to complete the remediation or
replacement of its critical systems, facilities and equipment, establish
alternative procedures in a timely manner, or if those with whom the Company
conducts business are unsuccessful in implementing timely solutions, Year 2000
issues could have a material adverse effect on the Company's liquidity and
results of operations. At this time, the potential effect in the event the
Company and/or third parties are unable to timely resolve their Year 2000
problems is not determinable; however, the Company currently believes that it
will be able to resolve its own Year 2000 issues in a timely manner.
 
    The disclosure set forth in this section is provided pursuant to Securities
Act Release No. 33-7558. As such it is protected as a forward-looking statement

Statements." This disclosure is also subject to protection under the Year 2000
Information and Readiness Disclosure Act of 1998, Public Law 105-271, as a "Year
2000 Statement" and "Year 2000 Readiness Disclosure" as defined therein.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
 
    The Company is exposed to market risk, including adverse changes in
commodity prices, interest rates and foreign currency exchange rates as
discussed below.
 
COMMODITY PRICE RISK
 
    The Company produces, purchases and sells natural gas, crude oil, condensate
and NGLs. As a result, the Company's financial results can be significantly
affected as these commodity prices fluctuate widely in response to changing
market forces. In the past, the Company has made limited use of a variety of
derivative financial instruments only for non-trading purposes as a hedging
strategy to manage commodity prices associated with oil and gas sales and to
reduce the impact of commodity price fluctuations. See "Business--Competition
and Market Conditions." As discussed earlier, the Company was not party to any
derivative financial instruments during 1998.
 
INTEREST RATE RISK
 
    From time to time, the Company has entered into various financial
instruments, such as interest rate swaps, to manage the impact of changes in
interest rates. Currently, the Company has no open interest rate
 
                                       38
<PAGE>
swap or interest rate lock agreements. Therefore, the Company's exposure to
changes in interest rates primarily results from its short-term and long-term
debt with both fixed and floating interest rates. The following table presents
principal or notional amounts (stated in thousands) and related average interest
rates by year of maturity for the Company's debt obligations and their indicated
fair market value at December 31, 1998:

</TABLE>
 
FOREIGN CURRENCY EXCHANGE RATE RISK
 
    The Company conducts business in Thai baht and the Canadian dollar and is
therefore subject to foreign currency exchange rate risk on cash flows related
to sales, expenses, financing and investing transactions. The Company conducts a
substantial portion of its oil and gas production and sales in Southeast Asia.
Southeast Asia in general, and the Kingdom of Thailand in particular, have
experienced severe economic difficulties, including sharply reduced economic
activity, illiquidity, highly volatile foreign currency exchange rates and
unstable stock markets. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Results of Operations; Foreign Currency
Transaction Gain (Loss") and "--Liquidity and Capital Resources; Other Matters;
Southeast Asia Economic Issues." However, the economic difficulties in Thailand
and the volatility of the Thai baht against the U.S. dollar will continue to
have a material impact on the Company's Thailand operations and prices that the
Company receives for its oil and gas production there. Although the Company's
sales to PTT under the Gas Sales Agreement are denominated in baht, because
predominantly all of the Company's crude oil sales and its capital and most
other expenditures in the Kingdom of Thailand are dominated in U.S. dollars, the
U.S. dollar is the functional currency for the Company's operations in the
Kingdom of Thailand.
 
    Exposure from market rate fluctuations related to activities in Canada,
where the Company's functional currency is the Canadian dollar, is not material
at this time.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders and Board of Directors of Pogo Producing Company:
 
    We have audited the accompanying consolidated balance sheets of Pogo
Producing Company (a Delaware corporation) and subsidiaries as of December 31,
1998 and 1997, and the related consolidated statements of income, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1998. These 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 financial statements referred to above present fairly,
in all material respects, the financial position of Pogo Producing Company and
subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
NATURE OF OPERATIONS
 
    Pogo Producing Company was incorporated in 1970. Pogo Producing Company and
its subsidiaries (the "Company") are engaged in oil and gas exploration,
development and production activities on its properties located offshore in the
Gulf of Mexico and onshore in the United States and Canada and internationally
in the Gulf of Thailand and the United Kingdom. The Company has interests in 105
lease blocks offshore Louisiana and Texas, approximately 303,000 gross acres
onshore in the United States, approximately 117,000 gross acres onshore in
Canada, approximately 734,000 gross acres offshore in the Kingdom of Thailand
and two lease blocks in the United Kingdom North Sea totaling approximately
113,000 gross acres.
 
ACQUISITION
 
    In August 1998, a wholly-owned subsidiary of the Company merged with Arch
Petroleum Inc. ("Arch") in a tax-free, stock for stock transaction, accounted
for as a purchase, through which Arch became a wholly owned subsidiary of the
Company.
 
    The merger agreement provided for a fixed exchange ratio of one share of the
Company's common stock for each 10.4 shares of Arch common stock. In addition,
holders of Arch preferred stock received one share of the Company's common stock
for each 1.04 shares of Arch preferred stock held. As a result, approximately
2,500,000 shares of the Company's common stock (valued at approximately $64.8
million) were issued in exchange for Arch preferred and common stock and its
convertible debt. The value of the approximately 2,500,000 shares of the
Company's common stock in excess of the book value of the net assets acquired
(approximately $52.9 million) has been allocated to oil and gas properties and
is being amortized using the units of production method over the life of the oil
and gas reserves acquired. Expenses related to the acquisition of approximately
$2,285,000 ($1,485,000 after taxes) have been expensed. Under the purchase
method of accounting for the acquisition, the Arch results of operations are
included in the consolidated results of operations from August 17, 1998, the
date of acquisition, through December 31, 1998.
 
    The following summary presents unaudited pro forma consolidated results of
operations as if the acquisition had occurred at the beginning of each period
presented. The pro forma results are for illustrative purposes only and are not
necessarily indicative of the operating results that would have occurred had the
acquisition been consummated at that date, nor are they necessarily indicative
of future operating results.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
USE OF ESTIMATES
 
    The preparation of these financial statements requires the use of certain
estimates by management in determining the Company's assets, liabilities,
revenues and expenses. Depreciation, depletion and amortization of oil and gas
properties and the impairment of oil and gas properties are determined using
estimates of proved oil and gas reserves. There are numerous uncertainties in
estimating the quantity of proved reserves and in projecting the future rates of
production and timing of development expenditures. Oil and gas reserve
engineering must be recognized as a subjective process of estimating underground
accumulations of oil and gas that cannot be measured in an exact way. Proved
reserves of crude oil, condensate, natural gas and natural gas liquids are
estimated quantities that geological and engineering data demonstrate with
reasonable certainty to be recoverable in the future from known reservoirs under
existing conditions.
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of Pogo Producing
Company and its subsidiary and affiliated companies, after elimination of all
significant intercompany transactions. Majority owned subsidiaries are fully
consolidated. Minority owned subsidiaries or affiliates are pro rata
consolidated in the same manner as the Company, and the oil and gas industry
generally, accounts for its operating or working interest in oil and gas joint
ventures.
 
PRIOR-YEAR RECLASSIFICATIONS
 
    Certain prior-year amounts have been reclassified to conform with the
current year presentation.
 
FOREIGN CURRENCY
 
    The U.S. dollar is the functional currency for all areas of operations of
the Company except Canada. Accordingly, monetary assets and liabilities and
items of income and expense denominated in a foreign currency are remeasured to
U.S. dollars at the rate of exchange in effect at the end of each month and the
resulting gains or losses on foreign currency transactions are included in the
consolidated statements of income for the period. The Canadian dollar is the
functional currency for the Company's Canadian operations. Accordingly, monetary
assets and liabilities and items of income and expense denominated in Canadian
dollars are translated to U.S. dollars at the rate of exchange in effect at the
end of each month and the resulting gains or losses on Canadian currency
transactions are included in the consolidated statement of shareholders' equity
for the period.
 
INVENTORY--PRODUCT
 
    Crude oil and condensate from the Company's Tantawan field located in the
Kingdom of Thailand is produced into a floating production, storage and off
loading ("FPSO") system and sold periodically as an economic barge quantity is
accumulated. The product inventory at December 31, 1998 consists of
approximately 90,000 barrels of crude oil and condensate, net to the Company's
interest, and is carried at its estimated net realizable value of $10.76 per
barrel.
 
INVENTORIES--TUBULARS
 
    Tubular Inventories consist primarily of goods used in the Company's
operations and are stated at the lower of average cost or market value.

INTEREST CAPITALIZED
 
    Interest costs related to financing major oil and gas projects in progress
are capitalized until the projects are evaluated or until production commences
if the projects are evaluated as successful.
 
EARNINGS PER SHARE
 
    Earnings (loss) per common share (basic earnings per share) are based on the
weighted average number of shares of common stock outstanding during the
periods. Earnings (loss) per common share and potential common share (diluted
earnings per share) consider the effect of dilutive securities as set out below
in thousands, except per share amounts.

(a) Computed on income before extraordinary item
 
PRODUCTION IMBALANCES
 
    Owners of an oil and gas property often take more or less production from a
property than entitled to based on their ownership percentages in the property.
This results in a condition known in the industry as a production imbalance. The
Company follows the "take" (cash) method of accounting for production
imbalances. Under this method, the Company recognizes revenues on production as
it is taken and delivered to its purchasers. The Company's crude oil imbalances
are not significant. At December 31, 1998, the Company had taken approximately
2,680 MMcf of natural gas less than it was entitled to based on its interest in
those properties, and approximately 2,363 MMcf more than its entitlement on
other properties placing the Company at year-end in a net under-delivered
position of approximately 317 MMcf of natural gas based on its working interest
ownership in the properties.
 
OIL AND GAS ACTIVITIES AND DEPRECIATION, DEPLETION AND AMORTIZATION
 
    The Company follows the successful efforts method of accounting for its oil
and gas activities. Under the successful efforts method, lease acquisition costs
and all development costs are capitalized. Proved properties are reviewed
whenever events or changes in circumstances indicate that the value of such
property on the Company's books may not be recoverable. Unproved properties are
reviewed quarterly to determine if there has been impairment of the carrying
value, with any such impairment charged to expense in the period. Proved oil and
gas properties are reviewed when circumstances suggest the need for such a
review and, if required, the proved properties are written down to their
estimated fair value. Estimated fair value includes the estimated present value
of all reasonably expected future production, prices, and costs. As a result of
poor reservoir performance and persistent low oil and gas prices, the Company
performed such a review in 1998 and expensed $30,813,000 related to its domestic
oil and gas properties which is included in the Consolidated Statements of
Income as dry hole and impairment expense. Exploratory drilling costs are
capitalized until the results are determined. If proved reserves are

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
not discovered, the exploratory drilling costs are expensed. Other exploratory
costs are expensed as incurred. The provision for depreciation, depletion and
amortization is based on the capitalized costs as determined above, plus future
costs to abandon offshore wells and platforms, and is on a cost center by cost
center basis using the units of production method. The Company generally creates
cost centers on a field by field basis for oil and gas activities in the Gulf of
Mexico and the Gulf of Thailand. Generally, the Company establishes cost centers
on the basis of an oil or gas trend or play for its onshore oil and gas
activities.
 
    In connection with the Company's ongoing asset rationalization process, the
Company has designated certain domestic oil and gas properties to be disposed of
during 1999. At the time of designation, no impairment loss was indicated. The
carrying amount of the properties at December 31, 1998 was $29,637,000, and they
contributed $7,253,000, $7,563,000 and $2,013,000 to operating income in 1998,
1997 and 1996, respectively.
 
    Other properties are depreciated using a straight-line method in amounts
which in the opinion of management are adequate to allocate the cost of the
properties over their estimated useful lives.
 
CONSOLIDATED STATEMENTS OF CASH FLOWS
 
    For the purpose of cash flows, the Company considers all highly liquid
investments with a maturity date of three months or less to be cash equivalents.
Significant transactions may occur which do not directly affect cash balances
and as such will not be disclosed in the Consolidated Statements of Cash Flows.
Certain such noncash transactions are disclosed in the Consolidated Statements
of Shareholders' Equity relating to shares issued in connection with the
Long-Term Incentive Plan and the conversion of debentures into Common Stock in
1997 and 1998 and the acquisition of Arch in 1998.
 
COMMITMENTS AND CONTINGENCIES
 
    The Company has commitments for operating leases for office space in
Houston, Midland, Calgary and Bangkok and commitments for an operating lease and
operating expenses related to an FPSO and FSO in the Gulf of Thailand. Rental
expense for office space was $1,545,000 in 1998, $1,440,000 in 1997, and
$1,054,000 in 1996. Expenses for the FPSO lease and related operating costs were
$15,864,000 in 1998 and $14,809,000 in 1997. Expenses for the FSO lease and
related operating costs are currently expected to commence in May or June of
1999, with total expenses for the floating storage and offloading system ("FSO")
estimated to be approximately $3,077,000 for 1999 and $5,215,000 in the year
2000 and each year thereafter. Future minimum office and FPSO lease expenses and
related FPSO operating expense payments (in thousands of dollars) at December
31, 1998, are as follows:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
(3) LONG-TERM DEBT (CONTINUED)
    Effective August 1, 1997, the Company entered into an amended and restated
bank revolving credit agreement (the "Credit Agreement"), which was amended,
most recently on December 21, 1998. The Credit Agreement provides for a
$200,000,000 revolving/term credit facility which will be fully revolving until
July 1, 2000, after which the balance will be due in eight quarterly
installments, commencing on October 31, 2000. The amount that may be borrowed
under the Credit Agreement may not exceed a borrowing base which is composed of
domestic, Canadian and Thai properties. Generally, the borrowing base is
determined semi-annually by the lenders in accordance with the Credit Agreement,
based on the lenders' usual and customary criteria for oil and gas transactions.
As of February 1, 1999, the Company's total borrowing base was set at
$140,000,000, which amount cannot be reduced until after April 30, 1999. The
Credit Agreement is governed by various financial and other covenants, including
requirements to maintain positive working capital (excluding current maturities
of debt) and a fixed charge coverage ratio, and limitations on indebtedness
(including a total indebtedness limit of $500,000,000), creation of liens, the
prepayment of subordinated debt, the payment of dividends, mergers and
consolidations, investments and asset dispositions. In addition, the Company is
prohibited from pledging borrowing base properties as security for other debt.
Borrowings under the Credit Agreement bear interest at a rate based upon the
percentage of the borrowing base that is being utilized, ranging from a base
(prime) rate or LIBOR plus 1.25% to a base rate plus 0.25% or LIBOR plus 2.0%,
at the Company's option. Borrowings under the Credit Agreement currently bear
interest at a base rate or LIBOR plus 1.75%, at the Company's option. A
commitment fee on the unborrowed amount under the Credit Agreement is also
charged and is based upon the percentage of the borrowing base that is being
utilized, ranging from 0.25% to 0.375%. The commitment fee is currently 0.375%
per annum on the unborrowed amount under the Credit Agreement. Due to
limitations on total indebtedness under the Credit Agreement, as of February 1,
1999, the Company may borrow up to $135,000,000 under the Credit Agreement and
its other senior debt arrangements.
 
    As of December 31, 1998, the Company is a party to separate letter
agreements with two banks under which one of the banks may provide a $10,000,000
uncommitted money market line of credit and the other bank may provide a
$20,000,000 uncommitted money market line of credit. Each line of credit is on
an as available or offered basis and neither bank has an obligation to make any
advances under its line of credit. Although loans made under these letter
agreements are for a maximum of 30 days, they are reflected as long-term debt on
the Company's balance sheet because the Company has the ability and intent to
reborrow such amounts under its Credit Agreement. Both letter agreements permit
either party to terminate such letter agreements at any time. Under the Credit
Agreement, the Company is currently limited to incurring a maximum of
$20,000,000 of additional senior debt, which would include debt incurred under
these lines of credit and under the banker's acceptances discussed below.
 
    On June 3, 1998, the Company entered into a Master Banker's Acceptance
Agreement under which one of the Company's lenders has offered to accept up to
$20,000,000 in bank drafts from the Company. The banker's drafts are available
on an uncommitted basis and the bank has no obligation to accept the Company's
request for drafts. Drafts drawn under this agreement are for a maximum term of
182 days; however, they are reflected as long-term debt on the Company's balance
sheet because the Company currently has the ability and intent to reborrow such
amounts under the Credit Agreement. The Master Banker's Acceptance Agreement
permits either party to terminate the letter agreement at any time upon five
business days notice.
 
    On May 22, 1997, the Company issued $100,000,000 of 8 3/4% Senior
Subordinated Notes, due 2007 (the "2007 Notes"). The 2007 Notes bear interest at
a rate of 8 3/4%, payable semi-annually in arrears on May 15 and November 15 of
each year. The 2007 Notes are general unsecured senior subordinated

obligations of the Company and are subordinated in right of payment to the
Company's senior indebtedness, which currently includes the Company's
obligations under the Credit Agreement, its unsecured credit lines, and its
banker's acceptances, are equal in right of payment to the 2009 Notes (defined
below) but are senior in right of payment to its subordinated indebtedness,
which currently includes the 2006 Notes. The Company, at its option, may redeem
the 2007 Notes in whole or in part, at any time on or after May 15, 2002, at a
redemption price of 104.375% of their principal value and decreasing percentages
thereafter. No sinking fund payments are required on the 2007 Notes. The 2007
Notes are redeemable at the option of any holder, upon the occurrence of a
change of control (as defined in the indenture governing the 2007 Notes), at
101% of their principal amount. The indenture governing the 2007 Notes also
imposes certain covenants on the Company that are substantially identical to the
covenants contained in the indenture governing the 2009 Notes, including
covenants limiting: incurrence of indebtedness including senior indebtedness;
restricted payments; the issuance and sales of restricted subsidiary capital
stock; transactions with affiliates; liens, disposition of proceeds of asset
sales; non-guarantor restricted subsidiaries; dividends and other payment
restrictions affecting restricted subsidiaries; and mergers; consolidations and
the sale of assets.
 
    The 5 1/2% Convertible Subordinated Notes, due 2006 (the "2006 Notes") are
convertible into Common Stock at $42.185 per share subject to adjustment upon
the occurrence of certain events. The 2006 Notes will be redeemable at the
option of the Company, in whole or in part, at any time on or after June 15,
1999, at a redemption price of 103.85% and decreasing percentages thereafter. No
sinking fund is provided. The 2006 Notes are redeemable at the option of the
holder, upon the occurrence of a repurchase event (a change in control and other
circumstances, as defined), at 100% of the principal amount.
 
    On February 12, 1998, the Company announced its intent to redeem the 5 1/2%
Convertible Subordinated Notes, due 2004 (the "2004 Notes") on March 16, 1998,
at 103.3% of their principal amount plus accrued interest. Holders of
$86,084,000 principal amount of the 2004 Notes elected to convert their notes
into 3,879,726 common shares at $22.188 per share plus $640 in cash for
fractional shares. The value of the shares issued was credited to common stock
and additional capital less unamortized debt issue expense applicable to the
2004 Notes. The remaining $95,000 principal amount of the 2004 Notes were
redeemed for $98,135 representing 103.3% of the principal amount of such 2004
Notes.
 
    Current maturities and sinking fund requirements during the next five years
in connection with the above long-term debt are none in 1999, $32,992,000 in
2000, $120,971,000 in 2001, $65,984,000 in 2002 and none in 2003. All of the
current maturities reflected above are related to the retirement of the
Company's bank debt. The Company has established a history of refinancing its
senior debt before scheduled maturity payments commence and expects to do so
again before the amortization of senior debt commences in 2000.
 
    On January 15, 1999, the Company issued $150,000,000 of 10 3/8% Senior
Subordinated Notes, due 2009 (the "2009 Notes"). The proceeds from the issuance
of the 2009 Notes were used to repay amounts outstanding under the Company's
Credit Agreement. The 2009 Notes bear interest at a rate of 10 3/8%, payable
semi-annually in arrears on February 15 and August 15 of each year, commencing
August 15, 1999. The 2009 Notes are generally unsecured senior subordinated
obligations of the Company and are subordinated in right of payment to the
Company's senior indebtedness, which currently includes the Company's
obligations under the Credit Agreement, its unsecured credit lines and bankers
acceptances, are equal in right of payment to the 2007 Notes, but are senior in
right of payment to its subordinated indebtedness, which includes the 2006
Notes. The Company, at its option, may redeem the 2009 Notes in whole or in
part, at any time on or after February 15, 2004, at a redemption price of
105.188% of their principal value and decreasing percentages thereafter. No
sinking fund payments are required on the 2009

Notes. The 2009 Notes are redeemable at the option of any holder, upon the
occurrence of a change in control (as defined in the indenture governing the
2009 Notes), at 101% of their principal amount. The indenture governing the 2009
Notes also imposes certain covenants on the Company that are substantially
identical to the covenants contained in the indenture governing the 2007 Notes.
As of February 1, 1999, $15,000,000 was available for dividends under this
limitation, which is currently the Company's most restrictive such covenant.

(6) CREDIT RISK
 
    Substantially all of the Company's accounts receivable at December 31, 1998
and 1997, result from oil and gas sales and joint interest billings to other
companies in the oil and gas industry. This concentration of customers and joint
interest owners may impact the Company's overall credit risk, either positively
or negatively, in that these entities may be similarly affected by industry-wide
changes in economic or other conditions. Such receivables are generally not
collateralized. Historically, credit losses incurred by the Company on
receivables have not been material. No material credit losses were experienced
during 1998 or 1997.
 
    A substantial portion of the Company's oil and gas operations are conducted
in Southeast Asia, and a substantial portion of its natural gas and liquids
hydrocarbon production are sold there. In the last two years, Southeast Asia in
general, and the Kingdom of Thailand in particular, have experienced severe
economic difficulties which have been characterized by sharply reduced economic
activity, illiquidity, highly volatile foreign currency exchange rates and
unstable stock markets. The government of the Kingdom of Thailand and other
governments in the region are currently acting to address these issues. However,
the economic difficulties currently being experienced in Thailand, together with
the volatility of the Thai Baht against the U.S. dollar, will continue to have a
material impact on the Company's operations in the Kingdom of Thailand together
with the prices that the Company receives for its oil and natural gas production
there.
 
    All of the Company's current natural gas production from its Thailand
operations are committed under a long-term Gas Sales Agreement to PTT at a price
denominated in Thai Baht. The Company's crude oil and condensate production from
its Thailand operations is currently sold on a tanker load by tanker load basis.
Prices that the Company receives for such crude oil production are based on
world benchmark prices, which are denominated in U.S. dollars and are generally
expected on future crude oil sales to be paid in U.S. dollars. The Company
believes that the current economic difficulties in Southeast Asia have resulted
in a decreased demand for petroleum products in the region, which has
contributed to the recent general decline in crude oil and condensate prices
throughout the world.
 
(7) EMPLOYEE BENEFITS
 
    The Company has a tax-advantaged savings plan in which all U.S. salaried
employees may participate. Under such plan, a participating employee may
allocate up to 10% of his salary, up to a maximum allowed by law ($10,000 for
1999), and the Company will then match the employee's contribution on a dollar
for dollar basis up to 6% of the employee's salary. Funds contributed by the
employee and the matching funds contributed by the Company are held in trust by
a bank trustee in six separate funds. Amounts contributed by the employee and

the savings plan in 1998, $588,000 in 1997, and $471,000 in 1996.
 
    A trusteed retirement plan has been adopted by the Company for its U.S.
salaried employees. The benefits are based on years of service and the
employee's average compensation for five consecutive years within the final ten
years of service which produce the highest average compensation. The Company
makes annual contributions to the plan in the amount of retirement plan cost
accrued or the maximum amount which can be deducted for federal income tax
purposes. Although the Company has no obligation to do so, the Company currently
provides full medical benefits to its retired U.S. employees and dependents. For
current employees, the Company assumes all or a portion of post retirement
medical and term life insurance costs based on the employee's age and length of
service with the Company. The post retirement medical plan has no assets and is
currently funded by the Company on a pay-as-you-go basis. The Company adopted

    For measurement purposes, a 7% annual rate of increase in the per capita
cost of covered health care benefits was assumed for 1999. The rate is assumed
to decrease gradually to 5% for 2003 and remain at that level thereafter.
 
    The accumulated post retirement benefit obligation at December 31 is
attributable to the following groups (in thousands of dollars):

(8) STOCK OPTION PLANS
 
    The Company's stock option plans authorize the granting of options to key
employees and non-employee directors at prices equivalent to the market value at
the date of grant. Options generally become exercisable in three annual
installments commencing one year after the date of grant and, if not exercised,
expire 10 years from the date of grant. The Company accounts for employee
stock-based compensation using the intrinsic value method and since the exercise
price of the options granted is equal to the quoted market price of the
Company's stock at the grant date, no compensation cost has been recognized for
its stock options plans. Had compensation costs been determined based on fair
value at the grant dates for awards made in 1998, 1997 and 1996, the Company's

    The Company occasionally enters into forward and futures contracts to
minimize the impact of oil and gas price fluctuations. However, the Company does
not consider its forward and futures contracts to be financial instruments since
these contracts require or permit settlement by the delivery of the underlying
commodity. Gains and losses on these activities are recognized in revenues when
the hedged production occurs. No such contracts were outstanding as of December
31, 1998 or 1997.
 
(10) COMPREHENSIVE INCOME
 
    During 1998, the Company adopted the Financial Accounting Standards Board's
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" ("SFAS 130"). Currently there are no significant amounts to be included
in the computation of comprehensive income of the Company, as defined, that are
required to be disclosed under the provisions of SFAS 130. The Company did
report a foreign currency translation loss of $1,207,000 in 1998 which is
reflected as a reduction of shareholders' equity and represents less than 2% of
the Company's reported pretax loss for 1998. As such, total comprehensive income
(loss) and net income (loss) are materially the same for each of the three years
in the period ended December 31, 1998.
 
(11) IMPACT OF SFAS 133--
 
    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair market value
and that changes in the derivative's fair market value be recognized currently
in earnings unless specific hedge accounting criteria are met. SFAS 133 is
effective for the Company in 2000 but early adoption is allowed. The Company has
not yet quantified the impacts of adopting SFAS 133 or determined the timing or
method of adoption. However, SFAS 133 could increase volatility in earnings and
other comprehensive income should the Company enter into transactions covered by
this pronouncement.

OIL AND GAS PRODUCING ACTIVITIES
 
    The results of operations from oil and gas producing activities excludes
non-oil and gas revenues, general and administrative expenses, interest charges,
interest income and interest capitalized. Income tax (expense) or benefit was
determined by applying the statutory rates to pre-tax operating results with
adjustments for permanent differences.

                   STANDARDIZED MEASURE OF DISCOUNTED FUTURE
 
  NET CASH FLOWS RELATED TO PROVED OIL AND GAS RESERVES--UNAUDITED--CONTINUED
 
    The standardized measure of discounted future net cash flows from the
production of proved reserves is developed as follows:
 
    1.  Estimates are made of quantities of proved reserves and the future
periods in which they are expected to be produced based on year end economic
conditions.
 
    2.  The estimated future gross revenues from proved reserves are priced on
the basis of year end prices, except in those instances where fixed and
determinable natural gas price escalations are covered by contracts.
 
    3.  The future gross revenue streams are reduced by estimated future costs
to develop and to produce the proved reserves, as well as certain abandonment
costs based on year end cost estimates, and the estimated effect of future
income taxes. These cost estimates are subject to some uncertainty, particularly
those estimates relating to the Company's properties located in the Kingdom of
Thailand.
 
    The standardized measure of discounted future net cash flows does not
purport to present the fair market value of the Company's oil and gas reserves.
An estimate of fair value would also take into account, among other things, the
recovery of reserves in excess of proved reserves, anticipated future changes in
prices and costs, a discount factor more representative of the time value of
money and the risks inherent in reserve estimates.
 
    The following are the principal sources of change in the standardized
measure of discounted future net cash flows. All amounts are related to changes
in reserves located in the United States,the Kingdom of Thailand, and Canada, as
noted.

                              1998 INCENTIVE PLAN

                                      OF

                             POGO PRODUCING COMPANY


          1.   OBJECTIVES.  The Pogo Producing Company 1998 Incentive Plan (the
"Plan") is designed to retain key employees, to encourage the sense of
proprietorship of such employees and to stimulate the active interest of such
persons in the development and financial success of Pogo Producing Company, a
Delaware corporation (the "Company"), and its Subsidiaries (as hereinafter
defined).  These objectives are to be accomplished by making awards under the
Plan and thereby providing Participants (as hereinafter defined) with a
proprietary interest in the growth and performance of the Company and its
Subsidiaries.

          2.   DEFINITIONS.  As used herein, the terms set forth below shall
have the following respective meanings:  

          "Award" means the grant of any form of nonqualified stock option or
stock appreciation right, stock award or cash award, whether granted singly, in
combination or in tandem, to a Participant who is an employee pursuant to any
applicable terms, conditions and limitations as the Committee may establish in
order to fulfill the objectives of the Plan.

          "Award Agreement" means a written agreement between the Company and a
Participant that sets forth the terms, conditions and limitations applicable to
an Award.

          "Board" means the Board of Directors of the Company.

          "Code" means the Internal Revenue Code of 1986, as amended from time
to time.

          "Committee" means the Compensation Committee of the Board or such
other committee of the Board as is designated by the Board to administer the
Plan.

          "Common Stock" means the Common Stock, par value $1.00 per share, of
the Company.

          "Fair Market Value" means, as of a particular date, (i) if shares of
Common Stock are listed on a national securities exchange, the mean between the
highest and lowest sales price per share of Common Stock on the consolidated
transaction reporting system for the principal such national securities exchange
on that date, or, if there shall have been no such sale so reported on that
date, on the last preceding date on which such a sale was so reported, (ii) if
shares of Common Stock are not so listed but are quoted on the NASDAQ National
Market System, the mean between the highest and lowest sales price per share of
Common Stock on the NASDAQ National Market System on that 


                                     -1-
<PAGE>

date, or, if there shall have been no such sale so reported on that date, on 
the last preceding date on which such a sale was so reported or (iii) if the 
Common Stock is not so listed or quoted, the mean between the closing bid and 
asked price on that date, or, if there are no quotations available for such 
date, on the last preceding date on which such quotations shall be available, 
as reported by NASDAQ, or, if not reported by NASDAQ, by the National 
Quotation Bureau, Inc.

          "Participant" means an employee of the Company or any of its
Subsidiaries to whom an Award has been made under this Plan.

          "Subsidiary" means any corporation of which the Company directly or
indirectly owns shares representing more than 50% of the voting power of all
classes or series of capital stock of such corporation which have the right to
vote generally on matters submitted to a vote of the shareholders of such
corporation.

          3.   ELIGIBILITY.  Key employees of the Company and its Subsidiaries
eligible for an Award under this Plan are those who hold positions of
responsibility and whose performance, in the judgment of the Committee, can have
a significant effect on the success of the Company and its Subsidiaries.

          4.   COMMON STOCK AVAILABLE FOR AWARDS.  There shall be available for
Awards granted wholly or partly in Common Stock (including rights or options
which may be exercised for or settled in Common Stock) during the term of this
Plan an aggregate of 500,000 shares of Common Stock.  The Board and the
appropriate officers of the Company shall from time to time take whatever
actions are necessary to file required documents with governmental authorities
and stock exchanges and transaction reporting systems to make shares of Common
Stock available for issuance pursuant to Awards.  Common Stock related to Awards
that are forfeited or terminated, expire unexercised, are settled in cash in
lieu of Stock or in a manner such that all or some of the shares covered by an
Award are not issued to a Participant, or are exchanged for Awards that do not
involve Common Stock, shall immediately become available for Awards hereunder. 
The Committee may from time to time adopt and observe such procedures concerning
the counting of shares against the Plan maximum as it may deem appropriate.

          5.   ADMINISTRATION.  This Plan shall be administered by the
Committee, which shall have full and exclusive power to interpret this Plan and
to adopt such rules, regulations and guidelines for carrying out this Plan as it
may deem necessary or proper, all of which powers shall be exercised in the best
interests of the Company and in keeping with the objectives of this Plan.  The
Committee shall consist of at least two members of the Board.  The Committee
may, in its discretion, provide for the extension of the exercisability of an
Award, accelerate the vesting or exercisability of an Award, eliminate or make
less restrictive any restrictions contained in an Award, waive any restriction
or other provision of this Plan or an Award or otherwise amend or modify an
Award in any manner that is either (i) not adverse to the Participant holding
such Award or (ii) consented to by such Participant.  The Committee may correct
any defect or supply any omission or reconcile any inconsistency in this Plan or
in any Award in the manner and to the extent the Committee deems necessary 


                                     -2-
<PAGE>

or desirable to carry it into effect.  Any decision of the Committee in the 
interpretation and administration of this Plan shall lie within its sole and 
absolute discretion and shall be final, conclusive and binding on all parties 
concerned.  No member of the Committee or officer of the Company to whom it 
has delegated authority in accordance with the provisions of Paragraph 6 of 
this Plan shall be liable for anything done or omitted to be done by him or 
her, by any member of the Committee or by any officer of the Company in 
connection with the performance of any duties under this Plan.

          6.   DELEGATION OF AUTHORITY.  The Committee may delegate to the Chief
Executive Officer and to other senior officers of the Company its duties under
this Plan pursuant to such conditions or limitations as the Committee may
establish.

          7.   AWARDS.  The Committee shall determine the type or types of
Awards to be made to each Participant under this Plan.  Each Award made
hereunder shall be embodied in an Award Agreement, which shall contain such
terms, conditions and limitations as shall be determined by the Committee in its
sole discretion and shall be signed by the Participant and by the Chief
Executive Officer or the Chief Administrative Officer of the Company for and on
behalf of the Company.  Awards may consist of those listed in this Paragraph 7
and may be granted singly, in combination or in tandem.  Awards may also be made
in combination or in tandem with, in replacement of, or as alternatives to,
grants or rights under this Plan or any other employee plan of the Company or
any of its Subsidiaries, including the plan of any acquired entity.  An Award
may provide for the granting or issuance of additional, replacement or
alternative Awards upon the occurrence of specified events, including the
exercise of the original Award granted to a Participant.

          (a)  STOCK OPTION.  An Award may consist of a right to purchase a
     specified number of shares of Common Stock at a specified price that is not
     less than the greater of (i) 50% of the Fair Market Value of the Common
     Stock on the date of grant and (ii) the par value of the Common Stock on
     the date of grant.

          (b)  STOCK APPRECIATION RIGHT.  An Award may consist of a right to
     receive a payment, in cash or Common Stock, equal to the excess of the Fair
     Market Value or other specified valuation of a specified number of shares
     of Common Stock on the date the stock appreciation right ("SAR") is
     exercised over a specified strike price, as set forth in the applicable
     Award Agreement.

          (c)  STOCK AWARD.  An Award may consist of Common Stock or may be
     denominated in units of Common Stock.  All or part of any stock award may
     be subject to conditions established by the Committee, and set forth in the
     Award Agreement, which may include, but are not limited to, continuous
     service with the Company and its Subsidiaries, achievement of specific
     business objectives, increases in specified indices, attaining specified
     growth rates and other comparable measurements of performance.  Such Awards
     may be based on Fair Market Value or other specified valuations.  The
     certificates evidencing shares of Common Stock issued in connection with a
     stock award shall contain appropriate legends and restrictions describing
     the terms and conditions of the restrictions applicable thereto.  As 


                                     -3-
<PAGE>

     used herein, "Restricted Stock" means Common Stock that is restricted or 
     subject to forfeiture provisions.

          (d)  CASH AWARD.  An Award may be denominated in cash with the amount
     of the eventual payment subject to future service and such other
     restrictions and conditions as may be established by the Committee, and set
     forth in the Award Agreement, including, but not limited to, continuous
     service with the Company and its Subsidiaries, achievement of specific
     business objectives, increases in specified indices, attaining specified
     growth rates and other comparable measurements of performance.

          8.   PAYMENT OF AWARDS.

          (a)  GENERAL.  Payment of Awards may be made in the form of cash or
     Common Stock or combinations thereof and may include such restrictions as
     the Committee shall determine, including, in the case of Common Stock,
     restrictions on transfer and forfeiture provisions.

          (b)  DEFERRAL.  With the approval of the Committee, payments in
     respect of Awards may be deferred, either in the form of installments or a
     future lump sum payment.  The Committee may permit selected Participants to
     elect to defer payments of some or all types of Awards in accordance with
     procedures established by the Committee.  Any deferred payment, whether
     elected by the Participant or specified by the Award Agreement or by the
     Committee, may be forfeited if and to the extent that the Award Agreement
     so provides.

          (c)  DIVIDENDS AND INTEREST.  Dividends or dividend equivalent rights
     may be extended to and made part of any Award denominated in Common Stock
     or units of Common Stock, subject to such terms, conditions and
     restrictions as the Committee may establish.  The Committee may also
     establish rules and procedures for the crediting of interest on deferred
     cash payments and dividend equivalents for deferred payments denominated in
     Common Stock or units of Common Stock.

          (d)  SUBSTITUTION OF AWARDS.  At the discretion of the Committee, a
     Participant may be offered an election to substitute an Award for another
     Award or Awards of the same or different type.

          9.   STOCK OPTION EXERCISE.  The price at which shares of Common Stock
may be purchased under a stock option shall be paid in full at the time of
exercise in cash or, if elected by the optionee, the optionee may purchase such
shares by means of tendering Common Stock or surrendering another Award,
including Restricted Stock, valued at Fair Market Value on the date of exercise,
or any combination thereof.  The Committee shall determine acceptable methods
for tendering Common Stock or other Awards to exercise a stock option as it
deems appropriate.  If permitted by the Committee, payment may be made by
successive exercises by the Participant.  The Committee may provide for loans
from the Company to an employee to permit the exercise or purchase of 


                                     -4-
<PAGE>

Awards and may provide for procedures to permit the exercise or purchase of 
Awards by use of the proceeds to be received from the sale of Common Stock 
issuable pursuant to an Award.  Unless otherwise provided in the applicable 
Award Agreement, in the event shares of Restricted Stock are tendered as 
consideration for the exercise of a stock option, a number of the shares 
issued upon the exercise of the stock option, equal to the number of shares 
of Restricted Stock used as consideration therefor, shall be subject to the 
same restrictions as the Restricted Stock so submitted as well as any 
additional restrictions that may be imposed by the Committee.

          10.  TAX WITHHOLDING.  The Company shall have the right to deduct
applicable taxes from any Award payment and withhold, at the time of delivery or
vesting of cash or shares of Common Stock under this Plan, an appropriate amount
of cash or number of shares of Common Stock or a combination thereof for payment
of taxes required by law or to take such other action as may be necessary in the
opinion of the Company to satisfy all obligations for withholding of such taxes.
The Committee may also permit withholding to be satisfied by the transfer to the
Company of shares of Common Stock theretofore owned by the holder of the Award
with respect to which withholding is required.  If shares of Common Stock are
used to satisfy tax withholding, such shares shall be valued based on the Fair
Market Value when the tax withholding is required to be made.

          11.  AMENDMENT, MODIFICATION, SUSPENSION OR TERMINATION.  The Board
may amend, modify, suspend or terminate this Plan for the purpose of meeting or
addressing any changes in legal requirements or for any other purpose permitted
by law, except that no amendment or alteration that would impair the rights of
any Participant under any Award previously granted to such Participant shall be
made without such Participant's consent.

          12.  TERMINATION OF EMPLOYMENT.  Upon the termination of employment by
a Participant, any unexercised, deferred or unpaid Awards shall be treated as
provided in the specific Award Agreement evidencing the Award.  In the event of
such a termination, the Committee may, in its discretion, provide for the
extension of the exercisability of an Award, accelerate the vesting or
exercisability of an Award, eliminate or make less restrictive any restrictions
contained in an Award, waive any restriction or other provision of this Plan or
an Award or otherwise amend or modify the Award in any manner that is either (i)
not adverse to such Participant or (ii) consented to by such Participant.

          13.  ASSIGNABILITY.  Unless otherwise determined by the Committee and
provided in the Award Agreement, no Award or any other benefit under this Plan
shall be assignable or otherwise transferable except by will or the laws of
descent and distribution or pursuant to a qualified domestic relations order as
defined by the Code or Title I of the Employee Retirement Income Security Act,
or the rules thereunder.  The Committee may prescribe and include in applicable
Award Agreements other restrictions on transfer.  Any attempted assignment of an
Award or any other benefit under this Plan in violation of this Paragraph 13
shall be null and void.

          14.  ADJUSTMENTS.

          (a)  The existence of outstanding Awards shall not affect in any
     manner the right or power of the Company or its shareholders to make or
     authorize any or all adjustments, recapitalizations, reorganizations or
     other changes in the capital stock of the Company or its business or any
     merger or consolidation of the Company, or any issue of bonds, debentures,
     preferred or prior preference stock (whether or not such issue is prior to,
     on a parity with or junior to the Common Stock) or Common Stock or the
     dissolution or liquidation of the Company, or any sale or transfer of all
     or any part of its assets or business, or any other corporate act or
     proceeding of any kind, whether or not of a character similar to that of
     the acts or proceedings enumerated above.

          (b)  In the event of any subdivision or consolidation of outstanding
     shares of Common Stock or declaration of a dividend payable in shares of
     Common Stock or capital reorganization or reclassification or other
     transaction involving an increase or reduction in the number of outstanding
     shares of Common Stock, then (i) the number of shares of Common Stock
     reserved under this Plan and covered by outstanding Awards denominated in
     Common Stock or units of Common Stock, (ii) the exercise or other price in
     respect of such Awards and (iii) the appropriate Fair Market Value and
     other price determinations for such Awards hereof shall each be
     proportionately adjusted by the Board to reflect such transaction.  In the
     event of any consolidation or merger of the Company with another
     corporation or entity, or the adoption by the Company of a plan of exchange
     affecting the Common Stock or any distribution to holders of Common Stock
     of securities or property (other than normal cash dividends or dividends
     payable in Common Stock), the Board shall make appropriate adjustments to
     (i) the number of shares of Common Stock reserved under this Plan and
     covered by outstanding Awards denominated in Common Stock or units of
     Common Stock, (ii) the exercise or other price in respect of such Awards
     and (iii) the appropriate Fair Market Value and other price determinations
     for such Awards to give effect to such transaction; provided that such
     adjustments shall only be such as necessary to maintain the proportionate
     interest of the holders of the Awards and preserve, without exceeding, the
     value of such Awards.  In the event of a corporate merger, consolidation,
     acquisition of property or stock, separation, reorganization or
     liquidation, the Board shall be authorized to issue or assume Awards by
     means of substitution of new Awards, as appropriate, for previously issued
     Awards or an assumption of previously issued Awards as part of such
     adjustment.

          15.  RESTRICTIONS.  No Common Stock or other form of payment shall be
issued with respect to any Award unless the Company shall be satisfied based on
the advice of its counsel that such issuance will be in compliance with
applicable federal and state securities laws.  Certificates evidencing shares of
Common Stock delivered under this Plan may be subject to such stop transfer
orders and other restrictions as the Committee may deem advisable under the
rules, regulations and other requirements of the Securities and Exchange
Commission, any securities exchange or transaction reporting system upon which
the Common Stock is then listed and any applicable federal 


                                     -6-
<PAGE>

and state securities laws.  The Committee may cause a legend or legends to be 
placed upon any such certificates to make appropriate reference to such 
restrictions.

          16.  UNFUNDED PLAN.  Insofar as it provides for Awards of cash, Common
Stock or rights thereto, this Plan shall be unfunded.  Although bookkeeping
accounts may be established with respect to Participants who are entitled to
cash, Common Stock or rights thereto under this Plan, any such accounts shall be
used merely as a bookkeeping convenience.  The Company shall not be required to
segregate any assets that may at any time be represented by cash, Common Stock
or rights thereto, nor shall this Plan be construed as providing for such
segregation, nor shall the Company nor the Board nor the Committee be deemed to
be a trustee of any cash, Common Stock or rights thereto to be granted under
this Plan.  Any liability or obligation of the Company to any Participant with
respect to a grant of cash, Common Stock or rights thereto under this Plan shall
be based solely upon any contractual obligations that may be created by this
Plan and any Award Agreement, and no such liability or obligation of the Company
shall be deemed to be secured by any pledge or other encumbrance on any property
of the Company.  Neither the Company nor the Board nor the Committee shall be
required to give any security or bond for the performance of any obligation that
may be created by this Plan.

          17.  GOVERNING LAW.  This Plan and all determinations made and actions
taken pursuant hereto, to the extent not otherwise governed by mandatory
provisions of the Code or the securities laws of the United States, shall be
governed by and construed in accordance with the laws of the State of Delaware.

          18.  EFFECTIVE DATE OF PLAN.  This Plan shall be effective as of
October 27, 1998, the date (the "Effective Date") it was approved by the Board.

          19.  PERMITTED TRANSFERS.  The Committee may, in its discretion,
authorize all or a portion of the Awards to be granted to a Participant to be on
terms which permit transfer by such Participant to the following "Permitted
Assignees:"

          (a)  any person who is a sibling of a Participant, a Parent of a
     Participant, or the spouse of Participant or a descendant of
     Participant, including any person adopted by Participant or by any of
     Participant's descendants, and including the descendants of any such
     adopted person, provided that the adoption is completed before the
     adopted person is eighteen years of age;

          (b)  the trustees of any trust holding properties with respect to
     which Permitted Assignees and Participant actuarially comprise more
     than seventy-five percent (75%) of the beneficial ownership at the
     time of the assignment, determined as provided below; and


                                     -7-
<PAGE>

          (c)  any corporation or other business entity which is wholly
     owned by Permitted Assignees and Participant at the time of the
     assignment (directly or indirectly).

In making the determination whether Permitted Assignees actuarially comprise
more than seventy-five percent (75%) of the beneficial ownership of properties
held in a trust at the time of an assignment to the trustees of the trust, the
following beneficial interests in the trust shall be ignored:

          (a)  any beneficial interest of a person who is lawfully married
     to a Permitted Assignee at the time of the assignment or who had been
     married to a Permitted Assignee at the time of the Permitted
     Assignee's death and has not remarried at the time of the assignment;
     and

          (b)  any beneficial interest represented by the existence of any
     power of appointment over the trust properties, even though the actual
     exercise of the power of appointment may constitute an assignment.

The beneficial interests which are not ignored as provided above (the "Relevant
Interests") shall be divided into two categories, those which are held for
Permitted Assignees and those which are not, and each category shall be valued
as provided under section 2512(a) of the Internal Revenue Code of 1986, as
amended, as if the beneficial interests were then assigned, even if those
interests are not assignable.  Permitted Assignees shall be deemed to comprise
more than seventy-five percent (75%) of the beneficial ownership of properties
held in a trust at the time of an assignment to the trustees of the trust if the
value of the Relevant Interests which are held for Permitted Assignees is more
than three times the value of the Relevant Interests which are not held for
Permitted Assignees.

Notwithstanding the foregoing, (x) there may be no consideration for any such 
transfer, (y), if applicable, the Award Agreement pursuant to which such 
Award is granted must be approved by the Committee, and must expressly 
provide for transferability in a manner consistent with this Paragraph 19, 
and (z) subsequent transfers of transferred Awards, shall be prohibited 
except those in accordance with Paragraph 13.  Following transfer, any such 
Awards shall continue to be subject to the same terms and conditions as were 
applicable immediately prior to transfer, provided that (i) in the event of 
termination of employment, Paragraph 12 hereof shall continue to be applied 
with respect to the original Participant, following which the Awards shall be 
exercisable by the transferee only to the extent, and for the periods 
specified in the Paragraph 12 and the applicable Award Agreement, (ii) the 
original Participant shall remain subject to the withholding tax provisions 
of Paragraph 10, and (iii) the Company shall have no duty or obligation to 
provide notice to a transferee of any action or event affecting the rights of 
the transferee under the Plan including, without limitation, any amendment, 
modification, suspension or termination of the Plan pursuant to Paragraph 11, 
the early termination of an Award pursuant to Paragraph 12, or adjustments to 
the amount of the Awards pursuant to Paragraph 14.

                        EXECUTIVE EMPLOYMENT AGREEMENT


              AGREEMENT by and between POGO PRODUCING COMPANY, a Delaware 
corporation (the "Company") and DAVID R. BEATHARD  (the "Executive"), dated 
as of the 1st day of February, 1999.

              The Board of Directors of the Company (the "Board"), has 
determined that it is in the best interests of the Company and its 
shareholders to assure that the Company will have the continued dedication of 
the Executive, and to provide the Executive with compensation and benefits 
arrangements which are competitive with those of other corporations and which 
ensure that the compensation and benefits expectations of the Executive will 
be satisfied.  The Board also believes it is imperative to diminish the 
inevitable distraction of the Executive by virtue of the personal 
uncertainties and risks created by a pending or threatened Change of Control 
and to encourage the Executive's full attention and dedication to the Company 
currently and in the event of any threatened or pending Change of Control, 
and to insure the continuation of favorable compensation and benefits upon a 
Change of Control.  Therefore, in order to accomplish these objectives, the 
Board has caused the Company to enter into this Agreement.

              NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS;

       1.     CERTAIN DEFINITIONS.  (a)  The "Effective Date" shall mean the 
date of this Agreement.

              (b)    The "Employment Period" shall mean the period commencing 
on the Effective Date and ending on the second anniversary of such date; 
provided, however, that on each annual anniversary of the Effective Date (the 
"Renewal Date"), the Employment Period shall be reviewed, to determine 
whether, in the discretion of the Company, it should be extended for one 
additional year so as to terminate two years from such Renewal Date.  Any 
such one year extension shall be effective only if, prior to the Renewal 
Date, the Company shall give notice to the Executive that the Employment 
Period shall be so extended.

       2.     CHANGE OF CONTROL.  For the purpose of this Agreement, a 
"Change of Control" shall mean:

              (a)    The acquisition by any individual, entity or group 
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities 
Exchange Act of 1934, as amended (the "Exchange Act")) (a "Person") of 
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the 
Exchange Act) of 20% or more of either (i) the then outstanding shares of 
common stock of the Company (the "Outstanding Company Common Stock") or (ii) 
the combined voting power of the then outstanding voting securities of the 
Company entitled to vote generally in the election of directors (the 
"Outstanding Company Voting Securities").

<PAGE>

              Notwithstanding anything in this Agreement to the contrary, the 
following shall not constitute a Change of Control:

              (i)    any acquisition directly from the Company (excluding an 
acquisition by virtue of the exercise of a conversion privilege),

              (ii)   any acquisition by the Company,

              (iii)  any acquisition by any employee benefit plan (or related 
trust) sponsored or maintained by the Company or any corporation controlled 
by the Company, or

              (iv)   any acquisition by State Farm Mutual Automobile 
Insurance Company and certain affiliates ("State Farm") or Klingenstein, 
Fields & Co., L.P. ("Klingenstein") ("Specified Stockholders") of beneficial 
ownership of Outstanding Company Voting Securities resulting in an 
accumulation of said securities up to and including the following amounts:

                     A.     In the case of State Farm, 30% of Outstanding 
Voting Securities, and 

                     B.     In the case of Klingenstein, 30% of Outstanding 
Voting Securities, or

              (v)    any acquisition by any corporation pursuant to a 
reorganization, merger or consolidation, if, following such reorganization, 
merger or consolidation, the conditions described in clauses (i), (ii) and 
(iii) of subsection (c) of this Section 2 are satisfied; or 

              (b)    Individuals who, as of the date hereof, constitute the 
Board (the "Incumbent Board") cease for any reason to constitute at least a 
majority of the Board; provided, however, that any individual becoming a 
director subsequent to the date hereof whose election, or nomination for 
election by the Company's shareholders, was approved by a vote of at least a 
majority of the directors then comprising the Incumbent Board shall be

but excluding, for this purpose, any such individual whose initial assumption 
of office occurs as a result of either an actual or threatened election 
contest (as such terms are used in Rule 14a-11 of Regulation 14A promulgated 
under the Exchange Act) or other actual or threatened solicitation of proxies 
or consents by or on behalf of a Person other than the Board; or 

              (c)    Approval by the shareholders of the Company of a

the Executive in its employ in accordance with the terms and provisions of 
this Agreement, for the Employment Period.

       4.     TERMS OF EMPLOYMENT.  (a)  POSITION AND DUTIES.  (i) During the 
Employment Period, (A) the Executive's position (including status, offices, 
titles and reporting requirements), authority, duties and responsibilities 
shall be at least commensurate in all material respects with the most 
significant of those held, exercised and assigned at any time during the 
90-day period immediately preceding the later of the Effective Date, the most 
recent Renewal Date or a Change of Control, if any, (the "Applicable Date") 
and (B) the Executive's services shall be performed at the 

                                      -3-

location where the Executive was employed immediately preceding the 
Applicable Date or any office which is the headquarters of the Company and is 
less than 35 miles from such location.

                     (ii)   During the Employment Period, and excluding any 
periods of vacation and sick leave to which the Executive is entitled, the 
Executive agrees to devote reasonable attention and time during normal 
business hours to the business and affairs of the Company.  During the 
Employment Period it shall not be a violation of this Agreement for the 
Executive to (A) serve on corporate, civic or charitable boards or 
committees, (B) deliver lectures, fulfill speaking engagements or teach at 
educational institutions and (C) manage personal investments, so long as such

business organized in other than corporate form without the consent of the

expressly understood and agreed that to the extent that any such activities 
have been conducted by the Executive prior to the Applicable Date, the 
continued conduct of such activities (or the conduct of activities similar in

responsibilities to the Company.

              (b)    COMPENSATION.  (i)   BASE SALARY.  During the Employment 
Period, the Executive shall receive an annual base salary ("Annual Base

period immediately preceding the month in which the Applicable Date occurs.  
During the Employment Period, the Annual Base Salary shall be reviewed at 
least annually and may be increased at any time and from time to time as 
shall be substantially consistent with increases in base salary generally 
awarded in the ordinary course of business to other executives of the Company 
and its affiliated companies.  Any increase in Annual Base Salary shall not

distinction is applicable), savings opportunities and retirement benefit 
opportunities, in each case, equal to the most favorable of those provided by 
the Company and its affiliated companies for the Executive under such plans, 
practices, policies and programs as in effect at any time during the 90-day 
period immediately preceding the Applicable Date.

welfare benefit plans, practices, policies and programs provided by the 
Company and its affiliated companies (including, without limitation, medical, 
prescription, dental, disability, salary continuance, employee life, group 
life, accidental death and travel accident insurance plans and programs) to 
the extent applicable generally to other executives of the Company and its 
affiliated companies.  Such plans, practices, policies and programs shall 
provide the Executive with benefits which are equal, in the aggregate, to the 
most favorable of such plans, practices, policies and programs in effect for 
the Executive at any time during the 90-day period immediately preceding the 
Applicable Date.  

                     (v)    EXPENSES.  During the Employment Period, the 
Executive shall be entitled to receive prompt reimbursement for all 
reasonable expenses incurred by the Executive in accordance with the most 
favorable policies, practices and procedures of the Company and its

                     (vi)   FRINGE BENEFITS.  During the Employment Period, 
the Executive shall be entitled to fringe benefits in accordance with the 
most favorable plans, practices, programs and policies of the Company and its 
affiliated companies in effect for the Executive at any time during the 
90-day period immediately preceding the Applicable Date.

                     (vii)  OFFICE AND SUPPORT STAFF.  During the Employment 
Period, the Executive shall be entitled to an office or offices of a size and 
with furnishings and other appointments, and to personal secretarial and 
other assistance, at least equal to the most favorable of the foregoing 
provided to the Executive by the Company and its affiliated companies at any 
time during the 90-day period immediately preceding the Applicable Date.

                     (viii) VACATION.  During the Employment Period, the 
Executive shall be entitled to paid vacation in accordance with the most 
favorable plans, policies, programs and practices of the Company and its 
affiliated companies as in effect for the Executive at any time during the 
90-day period immediately preceding the Applicable Date.  

       5.     TERMINATION OF EMPLOYMENT.  (a)  DEATH OR DISABILITY.  The 
Executive's employment shall terminate automatically upon the Executive's 
death during the Employment Period.  If the Company determines in good faith 
that the Disability of the Executive has occurred during the Employment 
Period (pursuant to the definition of Disability set forth below), it may 
give to the Executive written notice in accordance with Section 12(c) of this 
Agreement of its intention to terminate the Executive's employment.  In such 
event, the Executive's employment with the Company shall terminate effective 
on the 30th day after receipt of such notice by the Executive (the 
"Disability Effective Date"), provided that, within the 30 days after such 
receipt, the Executive shall not have returned to full-time performance of 
the Executive's duties.  For purposes of this Agreement, "Disability" shall 
mean the absence of the Executive from the Executive's duties with the 
Company on a full-time basis for 180 consecutive business days as a result of 
incapacity due to mental or physical illness which is determined to be total 
and permanent by a physician selected by 

                                      -5-
<PAGE>

the Company or its insurers and acceptable to the Executive or the 
Executive's legal representative (such agreement as to acceptability not to 
be withheld unreasonably).

              (b)    CAUSE.  The Company may terminate the Executive's 
employment during the Employment Period for Cause.  For purposes of this 
Agreement, "Cause" shall mean (i) a material violation by the Executive of 
the Executive's obligations under Section 4(a) of this Agreement (other than 
as a result of incapacity due to physical or mental illness) which is willful 
and deliberate on the Executive's part, which is committed in bad faith or 
without reasonable belief that such violation is in the best interests of the 
Company and which is not remedied in a reasonable period of time after 
receipt of written notice from the Company specifying such violation or (ii) 
the conviction of the Executive of a felony involving moral turpitude.

              (c)    GOOD REASON; WINDOW PERIOD; OTHER TERMINATIONS.  The 
Executive's employment may be terminated (i) during the Employment Period by 
the Executive for Good Reason, (ii) during the Window Period by the Executive 
without any reason or (iii) by Executive other than (A) for Good Reason or 
(B) during a Window Period.

              For purposes of this Agreement, the "Window Period" shall mean 
the 180-day period immediately following the date a Change of Control occurs. 
Anything in this Agreement to the contrary notwithstanding, if a Change of 
Control occurs and if the Executive's employment with the Company is 
terminated prior to the date on which the Change of Control occurs, and if it 
is reasonably demonstrated by the Executive that such termination of 
employment or cessation of status as an officer (i) was at the request of a 
third party who has taken steps reasonably calculated to effect the Change of 
Control or (ii) otherwise arose in connection with or anticipation of the 
Change of Control, then for all purposes of this Agreement the "date a Change 
of Control occurs" shall mean the date immediately prior to the date of such 
termination of employment or cessation of status as an officer.

              For purposes of this Agreement, "Good Reason" shall mean

              (i)    the assignment to the Executive of any duties 
inconsistent with the Executive's position (including status, offices, titles 
and reporting requirements), authority, duties or responsibilities as 
contemplated by Section 4(a) of this Agreement, or any other action by the 
Company which results in a diminution in such position, authority, duties or 
responsibilities excluding for this purpose an insubstantial or inadvertent 
action which is remedied by the Company promptly after receipt of notice 
thereof given by the Executive;

              (ii)   any failure by the Company to comply with any of the 
provisions of Section 4(b) of this Agreement, other than an insubstantial or 
inadvertent failure which is remedied by the Company promptly after receipt 
of notice thereof given by the Executive;

              (iii)  the Company's requiring the Executive to be based at any 
office or location other than that described in Section 4(a)(i)(B) hereof;  

              (iv)  any purported termination by the Company of the 
Executive's employment otherwise than as expressly permitted by this 
Agreement; or 

                                      -6-
<PAGE>

              (v)    any failure by the Company to comply with and satisfy 
Section 11(c) of this Agreement.

              (d)    NOTICE OF TERMINATION.  Any termination by the Company 
for Cause, or by the Executive without any reason during the Window Period or 
for Good Reason, shall be communicated by Notice of Termination to the other 
party hereto given in accordance with Section 12(c) of this Agreement.  For 
purposes of this Agreement, a "Notice of Termination" means a written notice 
which (i) indicates the specific termination provision in this Agreement 
relied upon, (ii) to the extent applicable, sets forth in reasonable detail 
the facts and circumstances claimed to provide a basis for termination of the 
Executive's employment under the provision so indicated and (iii) if the Date 
of Termination (as defined below) is other than the date of receipt of such 
notice, specifies the termination date (which date shall be not more than 
fifteen days after the giving of such notice).  The failure by the Executive 
or the Company to set forth in the Notice of Termination any fact or 
circumstance which contributes to a showing of Good Reason or Cause shall not 
waive any right of the Executive or the Company hereunder or preclude the 
Executive or the Company from asserting such fact or circumstance in 
enforcing the Executive's or the Company's right hereunder.

              (e)    DATE OF TERMINATION.  "Date of Termination" means (i) if 
the Executive's employment is terminated by the Company for Cause, or by the 
Executive during the Window Period or for Good Reason, the date of receipt of 
the Notice of Termination or any later date specified therein, as the case 
may be, (ii) if the Executive's employment is terminated by the Company other 
than for Cause or Disability, the Date of Termination shall be the date on 
which the Company notifies the Executive of such termination, (iii) if the 
Executive's employment is terminated by reason of death or Disability, the 
Date of Termination shall be the date of death of the Executive or the 
Disability Effective Date, as the case may be, and (iv) if the Executive's 
employment is terminated by the Executive other than for Good Reason or 
during a Window Period, the date of the receipt of the Notice of Termination 
or any later date specified therein.  

              6.     OBLIGATIONS OF THE COMPANY UPON TERMINATION.

              (a)    GOOD REASON OR DURING THE WINDOW PERIOD; OTHER THAN FOR 
CAUSE, DEATH OR DISABILITY.  If, during the Employment Period, the Company 
shall terminate the Executive's employment other than for Cause or Disability 
or the Executive shall terminate employment either for Good Reason or without 
any reason during the Window Period:

              (i)    the Company shall pay to the Executive in a lump sum in 
cash within 30 days after the Date of Termination the aggregate of the 
following amounts:

                     A.  the sum of (1) the Executive's Annual Base Salary 
through the Date of Termination to the extent not theretofore paid and (2) 
any compensation previously deferred by the Executive (together with any 
accrued interest or earnings thereon) and any accrued vacation pay, in each 
case to the extent not theretofore paid (the sum of the amounts described in 
clauses (1) and (2) shall be hereinafter referred to as the "Accrued 
Obligations"); and 

                                      -7-
<PAGE>

                     B.  the amount (such amount shall be hereinafter 
referred to as the "Severance Amount") equal to the product of (1) three and 
(2) the sum of (x) the Executive's Annual Base Salary and (y) any bonus 
described in Section 4(b)(ii) paid or payable in respect of the most recently 
completed fiscal year of the Company; and, provided further, that such amount 
shall be reduced by the present value (determined as provided in Section 
280G(d)(4) of the Internal Revenue Code of 1986, as amended (the "Code")) of 
any other amount of severance relating to salary or bonus continuation to be 
received by the Executive upon termination of employment of the Executive 
under any severance plan, severance policy or severance arrangement of the 
Company; and 

                     C.  a separate lump sum supplemental retirement benefit 
equal to the difference between (1) the actuarial equivalent (utilizing for 
this purpose the actuarial assumptions utilized with respect to the Employees 
Retirement Plan for Pogo Producing Company (or any successor plan thereto) 
(the "Retirement Plan") during the 90-day period immediately preceding the 
Applicable Date) of the benefit payable under the Retirement Plan and any 
supplemental and/or excess retirement plan of the Company and its affiliated 
companies providing benefits for the Executive (the "SERP") which the 
Executive would receive if the Executive's employment continued at the 
compensation level provided for in Sections 4(b)(i) and 4(b)(ii) of this 
Agreement for the remainder of the Employment Period, assuming for this 
purpose that all accrued benefits are fully vested and that benefit accrual 
formulas are no less advantageous to the Executive than those in effect 
during the 90-day period immediately preceding the Applicable Date, and (2) 
the actuarial equivalent (utilizing for this purpose the actuarial 
assumptions utilized with respect to the Retirement Plan during the 90-day 
period immediately preceding the Applicable Date) of the Executive's actual 
benefit (paid or payable), if any, under the Retirement Plan and the SERP 
(the amount of such benefit shall be hereinafter referred to as the 
"Supplemental Retirement Amount"); and 

              (ii)   for the remainder of the Employment Period, or such 
longer period as any plan, program, practice or policy may provide, the 
Company shall continue benefits to the Executive and/or the Executive's 
family at least equal to those which would have been provided to them in 
accordance with the plans, programs, practices and policies described in 
Section 4(b)(iv) of this Agreement if the Executive's employment had not been 
terminated in accordance with the most favorable plans, practices, programs 
or policies of the Company and its affiliated companies as in effect and 
applicable generally to other executives and their families during the 90-day 
period immediately preceding the Applicable Date, provided, however, that if 
the Executive becomes reemployed with another employer and is eligible to 
receive medical or other welfare benefits under another employer provided 
plan, the medical and other welfare benefits described herein shall be 
secondary to those provided under such other plan during such applicable 
period of eligibility (such continuation of such benefits for the applicable 
period herein set forth shall be hereinafter referred to as "Welfare Benefit 
Continuation").  For purposes of determining eligibility of the Executive for 
retiree benefits pursuant to such plans, practices, programs and policies, 
the Executive shall be considered to have remained employed until the end of 
the Employment Period and to have retired on the last day of such period; and 

              (iii)  to the extent not theretofore paid or provided, the 
Company shall timely pay or provide to the Executive and/or the Executive's 
family any other amounts or benefits required to 

                                      -8-
<PAGE>

be paid or provided or which the Executive and/or the Executive's family is 
eligible to receive pursuant to this Agreement and under any plan, program, 
policy or practice or contract or agreement of the Company and its affiliated 
companies as in effect and applicable generally to other executives and their 
families during the 90-day period immediately preceding the Applicable Date 
(such other amounts and benefits shall be hereinafter referred to as the 
"Other Benefits").  

              (b)    DEATH.  If the Executive's employment is terminated by 
reason of the Executive's death during the Employment Period, this Agreement 
shall terminate without further obligations to the Executive's legal 
representatives under this Agreement, other than for (i) payment of Accrued 
Obligations (which shall be paid to the Executive's estate or beneficiary, as 
applicable, in a lump sum in cash within 30 days of the Date of Termination) 
and the timely payment or provision of the Welfare Benefit Continuation and 
Other Benefits and (ii) payment to the Executive's estate or beneficiary, as 
applicable, in a lump sum in cash within 30 days of the Date of Termination 
of an amount equal to the sum of the Severance Amount and the Supplemental 
Retirement Amount.

              (c)    DISABILITY.  If the Executive's employment is terminated 
by reason of the Executive's Disability during the Employment Period, this 
Agreement shall terminate without further obligations to the Executive, other 
than for (i) payment of Accrued Obligations (which shall be paid to the 
Executive in a lump sum in cash within 30 days of the Date of Termination) 
and the timely payment or provision of the Welfare Benefit Continuation and 
Other Benefits (excluding, in each case, Disability Benefits (as defined 
below)) and (ii) payment to the Executive in a lump sum in cash within 30 
days of the Date of Termination of an amount equal to the greater of (A) the 
sum of the Severance Amount and the Supplemental Retirement Amount and (B) 
the present value (determined as provided in Section 280G(d)(4) of the Code) 
of any cash amount to be received by the Executive as a disability benefit 
pursuant to the terms of any long term disability plan, policy or arrangement 
of the Company and its affiliated companies, but not including any proceeds 
of disability insurance covering the Executive to the extent paid for on a 
contributory basis by the Executive (which shall be paid in any event as an 
Other Benefit) (the benefits included in this clause (B) shall be hereinafter 
referred to as the "Disability Benefits").

              (d)    CAUSE; BY EXECUTIVE OTHER THAN FOR GOOD REASON AND OTHER 
THAN DURING A WINDOW PERIOD.  If the Executive's employment shall be 
terminated for Cause during the Employment Period, this Agreement shall 
terminate without further obligations to the Executive other than the 
obligation to pay to the Executive Annual Base Salary through the Date of 
Termination plus the amount of any compensation previously deferred by the 
Executive, in each case to the extent theretofore unpaid.  If the Executive 
terminates employment during the Employment Period, excluding a termination 
either for Good Reason or without any reason during the Window Period, this 
Agreement shall terminate without further obligations to the Executive, other 
than for Accrued Obligations and the timely payment or provision of Other 
Benefits.  In such case, all Accrued Obligations shall be paid to the 
Executive in a lump sum in cash within 30 days of the Date of Termination.

       7.     NON-EXCLUSIVITY OF RIGHTS.  Except as provided in Section 
6(a)(ii), 6(b) and 6(c) of this Agreement, nothing in this Agreement shall 
prevent or limit the Executive's continuing or future participation in any 
plan, program, policy or practice provided by the Company or any of its 

                                      -9-
<PAGE>

affiliated companies and for which the Executive may qualify, nor shall 
anything herein limit or otherwise affect such rights as the Executive may 
have under any contract or agreement with the Company or any of its 
affiliated companies. Amounts which are vested benefits or which the 
Executive is otherwise entitled to receive under any plan, policy, practice 
or program of or any contract or agreement with the Company or any of its 
affiliated companies at or subsequent to the Date of Termination shall be 
payable in accordance with such plan, policy, practice or program or contract 
or agreement except as explicitly modified by this Agreement.

       8.     FULL SETTLEMENT; RESOLUTION OF DISPUTES.  (a) The Company's 
obligation to make payments provided for in this Agreement and otherwise to 
perform its obligations hereunder shall not be affected by any set-off, 
counterclaim, recoupment, defense or other claim, right or action which the 
Company may have against the Executive or others.  In no event shall the 
Executive be obligated to seek other employment or take any other action by 
way of mitigation of the amounts payable to the Executive under any of the 
provisions of this Agreement and, except as provided in Section 6(a)(ii) of 
this Agreement, such amounts shall not be reduced whether or not the 
Executive obtains other employment.  If there is any contest by the Company 
concerning the Payments or benefits to be provided to the Executive hereunder 
whether through litigation, arbitration or mediation, or with respect to the 
validity or enforceability of, or liability under, any provision of this 
Agreement or any guarantee of performance thereof, and the Executive is the 
prevailing party, the Company agrees to pay promptly upon conclusion of the 
contest all legal fees and expenses which the Executive may reasonably have 
incurred.

              (b)    If there shall be any dispute between the Company and 
the Executive (i) in the event of any termination of the Executive's 
employment by the Company, whether such termination was for Cause, or (ii) in 
the event of any termination of employment by the Executive, whether Good 
Reason existed, then, unless and until there is a final, nonappealable 
judgment by a court of competent jurisdiction declaring that such termination 
was for Cause or that Good Reason did not exist, the Company shall pay all 
amounts, and provide all benefits, to the Executive and/or the Executive's 
family or other beneficiaries, as the case may be, that the Company would be 
required to pay or provide pursuant to Section 6(a) hereof as though such 
termination were by the Company without Cause or by the Executive with Good 
Reason; provided, however, that the Company shall not be required to pay any 
disputed amounts pursuant to this paragraph except upon receipt of an 
undertaking (which need not be secured) by or on behalf of the Executive to 
repay all such amounts to which the Executive is ultimately adjudged by such 
court not to be entitled.

       9.     CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.  (a) Anything in 
this Agreement to the contrary notwithstanding, in the event it shall be 
determined that any payment or distribution by the Company to or for the 
benefit of the Executive (whether paid or payable or distributed or 
distributable pursuant to the terms of this Agreement or otherwise, but 
determined without regard to any additional payments required under this 
Section 9) (a "Payment") would be subject to the excise tax imposed by 
Section 4999 of the Code or any interest or penalties are incurred by the 
Executive with respect to such excise tax (such excise tax, together with any 
such interest and penalties, are hereinafter collectively referred to as the 
"Excise Tax"), then the Executive shall be entitled to receive an additional 
payment (a "Gross-Up Payment") in an amount such that after payment by the 
Executive of all taxes (including any interest or penalties imposed with 
respect to such taxes), including, without limitation, any income taxes (and 
any interest and penalties imposed 

                                      -10-
<PAGE>

with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the 
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax 
imposed upon the Payments.

              (b)    Subject to the provisions of Section 9(c), all 
determinations required to be made under this Section 9, including whether 
and when Gross-Up Payment is required and the amount of such Gross-Up Payment 
and the assumptions to be utilized in arriving at such determination, shall 
be made by Arthur Andersen LLP (the "Accounting Firm") which shall provide 
detailed supporting calculations both to the Company and the Executive within 
15 business days of the receipt of notice from the Executive that there has 
been a Payment, or such earlier time as is requested by the Company.  In the 
event that the Accounting Firm is serving as accountant or auditor for the 
individual, entity or group effecting the Change of Control, the Executive 
shall appoint another nationally recognized accounting firm to make the 
determinations required hereunder (which accounting firm shall then be 
referred to as the Accounting Firm hereunder).  All fees and expenses of the 
Accounting Firm shall be borne solely by the Company.  Any Gross-Up Payment, 
as determined pursuant to this Section 9, shall be paid by the Company to the 
Executive within five days of the receipt of the Accounting Firm's 
determination.  If the Accounting Firm determines that no Excise Tax is 
payable by the Executive, it shall furnish the Executive with a written 
opinion that failure to report the Excise Tax on the Executive's applicable 
federal income tax return would not result in the imposition of a negligence 
or similar penalty.  Any determination by the Accounting Firm shall be 
binding upon the Company and the Executive.  As a result of the uncertainty 
in the application of Section 4999 of the Code at the time of the initial 
determination by the Accounting Firm hereunder, it is possible that Gross-Up 
Payments which will not have been made by the Company should have been made 
("Underpayment"), consistent with the calculations required to be made 
hereunder.  In the event that the Company exhausts its remedies pursuant to 
Section 9(c) and the Executive thereafter is required to make a payment of 
any Excise Tax, the Accounting Firm shall determine the amount of the 
Underpayment that has occurred and any such Underpayment shall be promptly 
paid by the Company to or for the benefit of the Executive.

              (c)    The Executive shall notify the Company in writing of any 
claims by the Internal Revenue Service that, if successful, would require the 
payment by the Company of the Gross-Up Payment.  Such notification shall be 
given as soon as practicable but no later than ten business days after the 
Executive is informed in writing of such claim and shall apprise the Company 
of the nature of such claim and the date on which such claim is requested to 
be paid.  The Executive shall not pay such claim prior to the expiration of 
the 30-day period following the date on which it gives such notice to the 
Company (or such shorter period ending on the date that any payment of taxes 
with respect to such claim is due).  If the Company notifies the Executive in 
writing prior to the expiration of such period that it desires to contest 
such claim, the Executive shall:

              (i)    give the Company any information reasonably requested by 
the Company relating to such claim,

              (ii)   take such action in connection with contesting such 
claim as the Company shall reasonably request in writing from time to time, 
including, without limitation, accepting legal representation with respect to 
such claim by an attorney reasonably selected by the Company,

                                      -11-
<PAGE>

              (iii)  cooperate with the Company in good faith in order 
effectively to contest such claim, and

              (iv)   permit the Company to participate in any proceedings 
relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and 
expenses (including additional interest and penalties) incurred in connection 
with such contest and shall indemnify and hold the Executive harmless, on an 
after-tax basis, for any Excise Tax or income tax (including interest and 
penalties with respect thereto) imposed as a result of such representation 
and payment of costs and expenses.  Without limitation on the foregoing 
provisions of this Section 9(c), the Company shall control all proceedings 
taken in connection with such contest and, at its sole option, may pursue or 
forego any and all administrative appeals, proceedings, hearings and 
conferences with the taxing authority in respect of such claim and may, at 
its sole option, either direct the Executive to pay the tax claimed and sue 
for a refund or contest the claim in any permissible manner, and the 
Executive agrees to prosecute such contest to a determination before any 
administrative tribunal, in a court of initial jurisdiction and in one or 
more appellate courts, as the Company shall determine; provided, however, 
that if the Company directs the Executive to pay such claim and sue for a 
refund, the Company shall advance the amount of such payment to the 
Executive, on an interest-free basis and shall indemnify and hold the 
Executive harmless, on an after-tax basis, from any Excise Tax or income tax 
(including interest or penalties with respect thereto) imposed with respect 
to such advance or with respect to any imputed income with respect to such 
advance; and further provided that any extension of the statute of 
limitations relating to payment of taxes for the taxable year of the 
Executive with respect to which such contested amount is claimed to be due is 
limited solely to such contested amount.  Furthermore, the Company's control 
of the contest shall be limited to issues with respect to which a Gross-Up 
Payment would be payable hereunder and the Executive shall be entitled to 
settle or contest, as the case may be, any other issue raised by the Internal 
Revenue Service or any other taxing authority.

              (d)    If, after the receipt by the Executive of an amount 
advanced by the Company pursuant to Section (c), the Executive becomes 
entitled to receive any refund with respect to such claim, the Executive 
shall (subject to the Company's complying with the requirements of Section 
9(c)) promptly pay to the Company the amount of such refund (together with 
any interest paid or credited thereon after taxes applicable thereto).  If, 
after the receipt by the Executive of an amount advanced by the Company 
pursuant to Section 9(c), a determination is made that the Executive shall 
not be entitled to any refund with respect to such claim and the Company does 
not notify the Executive in writing of its intent to contest such denial of 
refund prior to the expiration of 30 days after such determination, then such 
advance shall be forgiven and shall not be required to be repaid and the 
amount of such advance shall be offset, to the extent thereof, the amount of 
Gross-Up Payment required to be paid.

       10.    CONFIDENTIAL INFORMATION.  The Executive shall hold in a 
fiduciary capacity for the benefit of the Company all secret or confidential 
information, knowledge or data relating to the Company or any of its 
affiliated companies, and their respective businesses, which shall have been 
obtained by the Executive during the Executive's employment by the Company or 
any of its affiliated companies and which shall not be or become public 
knowledge (other than by acts by the Executive or representatives of the 
Executive in violation of this Agreement).  After termination of 

                                      -12-
<PAGE>

the Executive's employment with the Company, the Executive shall not, without 
the prior written consent of the Company or as may otherwise be required by 
law or legal process, communicate or divulge any such information, knowledge 
or data to anyone other than the Company and those designated by it.  In no 
event shall an asserted violation of the provisions of this Section 10 
constitute a basis for deferring or withholding any amounts otherwise payable 
to the Executive under this Agreement.

       11.    SUCCESSORS.  (a) This Agreement is personal to the Executive 
and without the prior written consent of the Company shall not be assignable 
by the Executive otherwise than by will or the laws of descent and 
distribution.  This Agreement shall inure to the benefit of and be 
enforceable by the Executive's legal representatives.  

              (b)    This Agreement shall inure to the benefit of and be 
binding upon the Company and its successors and assigns.  

              (c)    The Company will require any successor (whether direct 
or indirect, by purchase, merger, consolidation or otherwise) to all or 
substantially all of the business and/or assets of the Company to assume 
expressly and agree to perform this Agreement in the same manner and to the 
same extent that the Company would be required to perform it if no such 
succession had taken place.  As used in this Agreement, "Company" shall mean 
the Company as hereinbefore defined and any successor to its business and/or 
assets as aforesaid which assumes and agrees to perform this Agreement by 
operation of law, or otherwise.

       12.    MISCELLANEOUS.  (a) This Agreement shall be an unfunded 
obligation of the Company.

              (b)    THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN 
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REFERENCE TO 
PRINCIPLES OF CONFLICT OF LAWS.  The captions of this Agreement are not part 
of the provisions hereof and shall have no force or effect.  This Agreement 
may not be amended or modified otherwise than by a written agreement executed 
by the parties hereto or their respective successors and legal 
representatives.

              (c)    All notices and other communications hereunder shall be 
in writing and shall be given by hand delivery to the other party or by 
registered or certified mail, return receipt requested, postage prepaid, 
addressed as follows:

                          Chief Administrative Officer


or to such other address as either party shall have furnished to the other in 
writing in accordance herewith.  Notice and communications shall be effective 
when actually received by the addressee.

              (d)    The invalidity or unenforceability of any provision of 
this Agreement shall not affect the validity or enforceability of any other 
provision of this Agreement.

              (e)    The Company may withhold from any amounts payable under 
this Agreement such Federal, state or local taxes as shall be required to be 
withheld pursuant to any applicable law or regulation.

              (f)    The Executive's or the Company's failure to insist upon 
strict compliance with any provision hereof or any other provision of this 
Agreement or the failure to assert any right the Executive or the Company may 
have hereunder, including, without limitation, the right of the Executive to 
terminate employment for Good Reason pursuant to Section 5(c)(i)-(v) of this 
Agreement, shall not be deemed to be a waiver of such provision or right or 
any other provision or right of this Agreement.

              IN WITNESS WHEREOF, the Executive has hereunto set the 
Executive's hand and, pursuant to the authorization from its Board of 
Directors, the Company has caused these presents to be executed in its name 
on its behalf, all as of the day and year first above written.

                        EXECUTIVE EMPLOYMENT AGREEMENT


              AGREEMENT by and between POGO PRODUCING COMPANY, a Delaware 
corporation (the "Company") and STEPHEN R. BRUNNER  (the "Executive"), dated 
as of the 1st day of February, 1999.

              The Board of Directors of the Company (the "Board"), has 
determined that it is in the best interests of the Company and its 
shareholders to assure that the Company will have the continued dedication of 
the Executive, and to provide the Executive with compensation and benefits 
arrangements which are competitive with those of other corporations and which 
ensure that the compensation and benefits expectations of the Executive will 
be satisfied.  The Board also believes it is imperative to diminish the 
inevitable distraction of the Executive by virtue of the personal 
uncertainties and risks created by a pending or threatened Change of Control 
and to encourage the Executive's full attention and dedication to the Company 
currently and in the event of any threatened or pending Change of Control, 
and to insure the continuation of favorable compensation and benefits upon a 
Change of Control.  Therefore, in order to accomplish these objectives, the 
Board has caused the Company to enter into this Agreement.

              NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS;

       1.     CERTAIN DEFINITIONS.  (a)  The "Effective Date" shall mean the 
date of this Agreement.

              (b)    The "Employment Period" shall mean the period commencing 
on the Effective Date and ending on the second anniversary of such date; 
provided, however, that on each annual anniversary of the Effective Date (the 
"Renewal Date"), the Employment Period shall be reviewed, to determine 
whether, in the discretion of the Company, it should be extended for one 
additional year so as to terminate two years from such Renewal Date.  Any 
such one year extension shall be effective only if, prior to the Renewal 
Date, the Company shall give notice to the Executive that the Employment 
Period shall be so extended.

       2.     CHANGE OF CONTROL.  For the purpose of this Agreement, a 
"Change of Control" shall mean:

              (a)    The acquisition by any individual, entity or group 
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities 
Exchange Act of 1934, as amended (the "Exchange Act")) (a "Person") of 
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the 
Exchange Act) of 20% or more of either (i) the then outstanding shares of 
common stock of the Company (the "Outstanding Company Common Stock") or (ii) 
the combined voting power of the then outstanding voting securities of the 
Company entitled to vote generally in the election of directors (the 
"Outstanding Company Voting Securities").

              Notwithstanding anything in this Agreement to the contrary, the 
following shall not constitute a Change of Control:

              (i)    any acquisition directly from the Company (excluding an 
acquisition by virtue of the exercise of a conversion privilege),

              (ii)   any acquisition by the Company,

              (iii)  any acquisition by any employee benefit plan (or related 
trust) sponsored or maintained by the Company or any corporation controlled 
by the Company, or

              (iv)   any acquisition by State Farm Mutual Automobile 
Insurance Company and certain affiliates ("State Farm") or Klingenstein, 
Fields & Co., L.P. ("Klingenstein") ("Specified Stockholders") of beneficial 
ownership of Outstanding Company Voting Securities resulting in an 
accumulation of said securities up to and including the following amounts:

                     A.     In the case of State Farm, 30% of Outstanding 
Voting Securities, and 

                     B.     In the case of Klingenstein, 30% of Outstanding 
Voting Securities, or

              (v)    any acquisition by any corporation pursuant to a 
reorganization, merger or consolidation, if, following such reorganization, 
merger or consolidation, the conditions described in clauses (i), (ii) and 
(iii) of subsection (c) of this Section 2 are satisfied; or 

              (b)    Individuals who, as of the date hereof, constitute the 
Board (the "Incumbent Board") cease for any reason to constitute at least a 
majority of the Board; provided, however, that any individual becoming a 
director subsequent to the date hereof whose election, or nomination for 
election by the Company's shareholders, was approved by a vote of at least a 
majority of the directors then comprising the Incumbent Board shall be 
considered as though such individual were a member of the Incumbent Board, 
but excluding, for this purpose, any such individual whose initial assumption 
of office occurs as a result of either an actual or threatened election 
contest (as such terms are used in Rule 14a-11 of Regulation 14A promulgated 
under the Exchange Act) or other actual or threatened solicitation of proxies 
or consents by or on behalf of a Person other than the Board; or 

              (c)    Approval by the shareholders of the Company of a 
reorganization, merger or consolidation, in each case, unless, following such

the then outstanding shares of common stock of the corporation resulting from 
such reorganization, merger or consolidation and the combined voting power of

Outstanding Company Common Stock and Outstanding Company Voting Securities, 
as the case may be, (B) no Person [excluding the Company, any Specified 
Stockholder, any employee benefit plan (or related trust) of the Company or

the Executive in its employ in accordance with the terms and provisions of 
this Agreement, for the Employment Period.

       4.     TERMS OF EMPLOYMENT.  (a)  POSITION AND DUTIES.  (i) During the 
Employment Period, (A) the Executive's position (including status, offices, 
titles and reporting requirements), authority, duties and responsibilities 
shall be at least commensurate in all material respects with the most 
significant of those held, exercised and assigned at any time during the 
90-day period immediately preceding the later of the Effective Date, the most 
recent Renewal Date or a Change of Control, if any, (the "Applicable Date") 
and (B) the Executive's services shall be performed at the 

                                      -3-

location where the Executive was employed immediately preceding the 
Applicable Date or any office which is the headquarters of the Company and is 
less than 35 miles from such location.

                     (ii)   During the Employment Period, and excluding any 
periods of vacation and sick leave to which the Executive is entitled, the 
Executive agrees to devote reasonable attention and time during normal 
business hours to the business and affairs of the Company.  During the 
Employment Period it shall not be a violation of this Agreement for the 
Executive to (A) serve on corporate, civic or charitable boards or 
committees, (B) deliver lectures, fulfill speaking engagements or teach at 
educational institutions and (C) manage personal investments, so long as such 
activities do not significantly interfere with the performance of the 
Executive's responsibilities as an employee of the Company in accordance with 
this Agreement; provided Executive may not serve on the board of a publicly 
traded for profit corporation or similar body of a publicly traded for profit 
business organized in other than corporate form without the consent of the 
Compensation Committee of the Board of Directors of the Company.  It is 
expressly understood and agreed that to the extent that any such activities 
have been conducted by the Executive prior to the Applicable Date, the 
continued conduct of such activities (or the conduct of activities similar in 
nature and scope thereto) subsequent to the Applicable Date shall not 
thereafter be deemed to interfere with the performance of the Executive's 
responsibilities to the Company.

              (b)    COMPENSATION.  (i)   BASE SALARY.  During the Employment 
Period, the Executive shall receive an annual base salary ("Annual Base 
Salary"), which shall be paid on a monthly basis, at least equal to twelve 
times the highest  monthly base salary paid or payable to the Executive by 
the Company and its affiliated companies in respect of the twelve-month 
period immediately preceding the month in which the Applicable Date occurs.  
During the Employment Period, the Annual Base Salary shall be reviewed at 
least annually and may be increased at any time and from time to time as 
shall be substantially consistent with increases in base salary generally 
awarded in the ordinary course of business to other executives of the Company 
and its affiliated companies.  Any increase in Annual Base Salary shall not 
serve to limit or reduce any other obligation to the Executive under this 
Agreement.  As used in this Agreement, the term "affiliated companies" shall 
include any company controlled by, controlling or under common control with 
the Company.

                     (ii)   ANNUAL BONUS.  In addition to Annual Base Salary,

applicable generally to other executives of the Company and its affiliated 
companies.  Such plans, practices, policies and programs shall provide the 
Executive with incentive opportunities (measured with respect to both regular 
and special incentive opportunities, to the extent, if any, that such 
distinction is applicable), savings opportunities and retirement benefit 
opportunities, in each case, equal to the most favorable of those provided by 
the Company and its affiliated companies for the Executive under such plans, 
practices, policies and programs as in effect at any time during the 90-day 
period immediately preceding the Applicable Date.

Period, the Executive and/or the Executive's family, as the case may be, 
shall be eligible for participation in and shall receive all benefits under 
welfare benefit plans, practices, policies and programs provided by the 
Company and its affiliated companies (including, without limitation, medical, 
prescription, dental, disability, salary continuance, employee life, group 
life, accidental death and travel accident insurance plans and programs) to 
the extent applicable generally to other executives of the Company and its 
affiliated companies.  Such plans, practices, policies and programs shall 
provide the Executive with benefits which are equal, in the aggregate, to the 
most favorable of such plans, practices, policies and programs in effect for 
the Executive at any time during the 90-day period immediately preceding the 
Applicable Date.  

                     (v)    EXPENSES.  During the Employment Period, the 
Executive shall be entitled to receive prompt reimbursement for all 
reasonable expenses incurred by the Executive in accordance with the most

most favorable plans, practices, programs and policies of the Company and its 
affiliated companies in effect for the Executive at any time during the 
90-day period immediately preceding the Applicable Date.

                     (vii)  OFFICE AND SUPPORT STAFF.  During the Employment 
Period, the Executive shall be entitled to an office or offices of a size and 
with furnishings and other appointments, and to personal secretarial and 
other assistance, at least equal to the most favorable of the foregoing 
provided to the Executive by the Company and its affiliated companies at any 
time during the 90-day period immediately preceding the Applicable Date.

                     (viii) VACATION.  During the Employment Period, the 
Executive shall be entitled to paid vacation in accordance with the most 
favorable plans, policies, programs and practices of the Company and its 
affiliated companies as in effect for the Executive at any time during the 
90-day period immediately preceding the Applicable Date.  

       5.     TERMINATION OF EMPLOYMENT.  (a)  DEATH OR DISABILITY.  The 
Executive's employment shall terminate automatically upon the Executive's 
death during the Employment Period.  If the Company determines in good faith 
that the Disability of the Executive has occurred during the Employment 
Period (pursuant to the definition of Disability set forth below), it may 
give to the Executive written notice in accordance with Section 12(c) of this 
Agreement of its intention to terminate the Executive's employment.  In such 
event, the Executive's employment with the Company shall terminate effective 
on the 30th day after receipt of such notice by the Executive (the 
"Disability Effective Date"), provided that, within the 30 days after such 
receipt, the Executive shall not have returned to full-time performance of 
the Executive's duties.  For purposes of this Agreement, "Disability" shall 
mean the absence of the Executive from the Executive's duties with the 
Company on a full-time basis for 180 consecutive business days as a result of 
incapacity due to mental or physical illness which is determined to be total 
and permanent by a physician selected by 

                                      -5-
<PAGE>

the Company or its insurers and acceptable to the Executive or the 
Executive's legal representative (such agreement as to acceptability not to 
be withheld unreasonably).

              (b)    CAUSE.  The Company may terminate the Executive's 
employment during the Employment Period for Cause.  For purposes of this 
Agreement, "Cause" shall mean (i) a material violation by the Executive of 
the Executive's obligations under Section 4(a) of this Agreement (other than 
as a result of incapacity due to physical or mental illness) which is willful 
and deliberate on the Executive's part, which is committed in bad faith or 
without reasonable belief that such violation is in the best interests of the 
Company and which is not remedied in a reasonable period of time after 
receipt of written notice from the Company specifying such violation or (ii) 
the conviction of the Executive of a felony involving moral turpitude.

              (c)    GOOD REASON; WINDOW PERIOD; OTHER TERMINATIONS.  The 
Executive's employment may be terminated (i) during the Employment Period by 
the Executive for Good Reason, (ii) during the Window Period by the Executive 
without any reason or (iii) by Executive other than (A) for Good Reason or 
(B) during a Window Period.

              For purposes of this Agreement, the "Window Period" shall mean 
the 180-day period immediately following the date a Change of Control occurs. 
Anything in this Agreement to the contrary notwithstanding, if a Change of 
Control occurs and if the Executive's employment with the Company is 
terminated prior to the date on which the Change of Control occurs, and if it 
is reasonably demonstrated by the Executive that such termination of 
employment or cessation of status as an officer (i) was at the request of a 
third party who has taken steps reasonably calculated to effect the Change of 
Control or (ii) otherwise arose in connection with or anticipation of the 
Change of Control, then for all purposes of this Agreement the "date a Change 
of Control occurs" shall mean the date immediately prior to the date of such 
termination of employment or cessation of status as an officer.

              For purposes of this Agreement, "Good Reason" shall mean

              (i)    the assignment to the Executive of any duties 
inconsistent with the Executive's position (including status, offices, titles 
and reporting requirements), authority, duties or responsibilities as 
contemplated by Section 4(a) of this Agreement, or any other action by the 
Company which results in a diminution in such position, authority, duties or 
responsibilities excluding for this purpose an insubstantial or inadvertent 
action which is remedied by the Company promptly after receipt of notice 
thereof given by the Executive;

              (ii)   any failure by the Company to comply with any of the 
provisions of Section 4(b) of this Agreement, other than an insubstantial or 
inadvertent failure which is remedied by the Company promptly after receipt 
of notice thereof given by the Executive;

              (iii)  the Company's requiring the Executive to be based at any 
office or location other than that described in Section 4(a)(i)(B) hereof;  

              (iv)  any purported termination by the Company of the 
Executive's employment otherwise than as expressly permitted by this 
Agreement; or 

                                      -6-
<PAGE>

              (v)    any failure by the Company to comply with and satisfy 
Section 11(c) of this Agreement.

              (d)    NOTICE OF TERMINATION.  Any termination by the Company 
for Cause, or by the Executive without any reason during the Window Period or 
for Good Reason, shall be communicated by Notice of Termination to the other 
party hereto given in accordance with Section 12(c) of this Agreement.  For 
purposes of this Agreement, a "Notice of Termination" means a written notice 
which (i) indicates the specific termination provision in this Agreement 
relied upon, (ii) to the extent applicable, sets forth in reasonable detail 
the facts and circumstances claimed to provide a basis for termination of the 
Executive's employment under the provision so indicated and (iii) if the Date 
of Termination (as defined below) is other than the date of receipt of such 
notice, specifies the termination date (which date shall be not more than 
fifteen days after the giving of such notice).  The failure by the Executive 
or the Company to set forth in the Notice of Termination any fact or 
circumstance which contributes to a showing of Good Reason or Cause shall not 
waive any right of the Executive or the Company hereunder or preclude the 
Executive or the Company from asserting such fact or circumstance in 
enforcing the Executive's or the Company's right hereunder.

              (e)    DATE OF TERMINATION.  "Date of Termination" means (i) if 
the Executive's employment is terminated by the Company for Cause, or by the 
Executive during the Window Period or for Good Reason, the date of receipt of 
the Notice of Termination or any later date specified therein, as the case 
may be, (ii) if the Executive's employment is terminated by the Company other 
than for Cause or Disability, the Date of Termination shall be the date on 
which the Company notifies the Executive of such termination, (iii) if the 
Executive's employment is terminated by reason of death or Disability, the 
Date of Termination shall be the date of death of the Executive or the 
Disability Effective Date, as the case may be, and (iv) if the Executive's 
employment is terminated by the Executive other than for Good Reason or 
during a Window Period, the date of the receipt of the Notice of Termination 
or any later date specified therein.  

              6.     OBLIGATIONS OF THE COMPANY UPON TERMINATION.

              (a)    GOOD REASON OR DURING THE WINDOW PERIOD; OTHER THAN FOR 
CAUSE, DEATH OR DISABILITY.  If, during the Employment Period, the Company 
shall terminate the Executive's employment other than for Cause or Disability 
or the Executive shall terminate employment either for Good Reason or without 
any reason during the Window Period:

              (i)    the Company shall pay to the Executive in a lump sum in 
cash within 30 days after the Date of Termination the aggregate of the 
following amounts:

                     A.  the sum of (1) the Executive's Annual Base Salary 
through the Date of Termination to the extent not theretofore paid and (2) 
any compensation previously deferred by the Executive (together with any 
accrued interest or earnings thereon) and any accrued vacation pay, in each 
case to the extent not theretofore paid (the sum of the amounts described in 
clauses (1) and (2) shall be hereinafter referred to as the "Accrued 
Obligations"); and 

                                      -7-
<PAGE>

                     B.  the amount (such amount shall be hereinafter 
referred to as the "Severance Amount") equal to the product of (1) three and 
(2) the sum of (x) the Executive's Annual Base Salary and (y) any bonus 
described in Section 4(b)(ii) paid or payable in respect of the most recently 
completed fiscal year of the Company; and, provided further, that such amount 
shall be reduced by the present value (determined as provided in Section 
280G(d)(4) of the Internal Revenue Code of 1986, as amended (the "Code")) of 
any other amount of severance relating to salary or bonus continuation to be 
received by the Executive upon termination of employment of the Executive 
under any severance plan, severance policy or severance arrangement of the 
Company; and 

                     C.  a separate lump sum supplemental retirement benefit 
equal to the difference between (1) the actuarial equivalent (utilizing for 
this purpose the actuarial assumptions utilized with respect to the Employees 
Retirement Plan for Pogo Producing Company (or any successor plan thereto) 
(the "Retirement Plan") during the 90-day period immediately preceding the 
Applicable Date) of the benefit payable under the Retirement Plan and any 
supplemental and/or excess retirement plan of the Company and its affiliated 
companies providing benefits for the Executive (the "SERP") which the 
Executive would receive if the Executive's employment continued at the 
compensation level provided for in Sections 4(b)(i) and 4(b)(ii) of this 
Agreement for the remainder of the Employment Period, assuming for this 
purpose that all accrued benefits are fully vested and that benefit accrual 
formulas are no less advantageous to the Executive than those in effect 
during the 90-day period immediately preceding the Applicable Date, and (2) 
the actuarial equivalent (utilizing for this purpose the actuarial 
assumptions utilized with respect to the Retirement Plan during the 90-day 
period immediately preceding the Applicable Date) of the Executive's actual 
benefit (paid or payable), if any, under the Retirement Plan and the SERP 
(the amount of such benefit shall be hereinafter referred to as the 
"Supplemental Retirement Amount"); and 

              (ii)   for the remainder of the Employment Period, or such 
longer period as any plan, program, practice or policy may provide, the 
Company shall continue benefits to the Executive and/or the Executive's 
family at least equal to those which would have been provided to them in 
accordance with the plans, programs, practices and policies described in 
Section 4(b)(iv) of this Agreement if the Executive's employment had not been 
terminated in accordance with the most favorable plans, practices, programs 
or policies of the Company and its affiliated companies as in effect and 
applicable generally to other executives and their families during the 90-day 
period immediately preceding the Applicable Date, provided, however, that if 
the Executive becomes reemployed with another employer and is eligible to 
receive medical or other welfare benefits under another employer provided 
plan, the medical and other welfare benefits described herein shall be 
secondary to those provided under such other plan during such applicable 
period of eligibility (such continuation of such benefits for the applicable 
period herein set forth shall be hereinafter referred to as "Welfare Benefit 
Continuation").  For purposes of determining eligibility of the Executive for 
retiree benefits pursuant to such plans, practices, programs and policies, 
the Executive shall be considered to have remained employed until the end of 
the Employment Period and to have retired on the last day of such period; and 

              (iii)  to the extent not theretofore paid or provided, the 
Company shall timely pay or provide to the Executive and/or the Executive's 
family any other amounts or benefits required to 

                                      -8-
<PAGE>

be paid or provided or which the Executive and/or the Executive's family is 
eligible to receive pursuant to this Agreement and under any plan, program, 
policy or practice or contract or agreement of the Company and its affiliated 
companies as in effect and applicable generally to other executives and their 
families during the 90-day period immediately preceding the Applicable Date 
(such other amounts and benefits shall be hereinafter referred to as the 
"Other Benefits").  

              (b)    DEATH.  If the Executive's employment is terminated by 
reason of the Executive's death during the Employment Period, this Agreement 
shall terminate without further obligations to the Executive's legal 
representatives under this Agreement, other than for (i) payment of Accrued 
Obligations (which shall be paid to the Executive's estate or beneficiary, as 
applicable, in a lump sum in cash within 30 days of the Date of Termination) 
and the timely payment or provision of the Welfare Benefit Continuation and 
Other Benefits and (ii) payment to the Executive's estate or beneficiary, as 
applicable, in a lump sum in cash within 30 days of the Date of Termination 
of an amount equal to the sum of the Severance Amount and the Supplemental 
Retirement Amount.

              (c)    DISABILITY.  If the Executive's employment is terminated 
by reason of the Executive's Disability during the Employment Period, this 
Agreement shall terminate without further obligations to the Executive, other 
than for (i) payment of Accrued Obligations (which shall be paid to the 
Executive in a lump sum in cash within 30 days of the Date of Termination) 
and the timely payment or provision of the Welfare Benefit Continuation and 
Other Benefits (excluding, in each case, Disability Benefits (as defined 
below)) and (ii) payment to the Executive in a lump sum in cash within 30 
days of the Date of Termination of an amount equal to the greater of (A) the 
sum of the Severance Amount and the Supplemental Retirement Amount and (B) 
the present value (determined as provided in Section 280G(d)(4) of the Code) 
of any cash amount to be received by the Executive as a disability benefit 
pursuant to the terms of any long term disability plan, policy or arrangement 
of the Company and its affiliated companies, but not including any proceeds 
of disability insurance covering the Executive to the extent paid for on a 
contributory basis by the Executive (which shall be paid in any event as an 
Other Benefit) (the benefits included in this clause (B) shall be hereinafter 
referred to as the "Disability Benefits").

              (d)    CAUSE; BY EXECUTIVE OTHER THAN FOR GOOD REASON AND OTHER 
THAN DURING A WINDOW PERIOD.  If the Executive's employment shall be 
terminated for Cause during the Employment Period, this Agreement shall 
terminate without further obligations to the Executive other than the 
obligation to pay to the Executive Annual Base Salary through the Date of 
Termination plus the amount of any compensation previously deferred by the 
Executive, in each case to the extent theretofore unpaid.  If the Executive 
terminates employment during the Employment Period, excluding a termination 
either for Good Reason or without any reason during the Window Period, this 
Agreement shall terminate without further obligations to the Executive, other 
than for Accrued Obligations and the timely payment or provision of Other 
Benefits.  In such case, all Accrued Obligations shall be paid to the 
Executive in a lump sum in cash within 30 days of the Date of Termination.

       7.     NON-EXCLUSIVITY OF RIGHTS.  Except as provided in Section 
6(a)(ii), 6(b) and 6(c) of this Agreement, nothing in this Agreement shall 
prevent or limit the Executive's continuing or future participation in any 
plan, program, policy or practice provided by the Company or any of its 

                                      -9-
<PAGE>

affiliated companies and for which the Executive may qualify, nor shall 
anything herein limit or otherwise affect such rights as the Executive may 
have under any contract or agreement with the Company or any of its 
affiliated companies. Amounts which are vested benefits or which the 
Executive is otherwise entitled to receive under any plan, policy, practice 
or program of or any contract or agreement with the Company or any of its 
affiliated companies at or subsequent to the Date of Termination shall be 
payable in accordance with such plan, policy, practice or program or contract 
or agreement except as explicitly modified by this Agreement.

       8.     FULL SETTLEMENT; RESOLUTION OF DISPUTES.  (a) The Company's 
obligation to make payments provided for in this Agreement and otherwise to 
perform its obligations hereunder shall not be affected by any set-off, 
counterclaim, recoupment, defense or other claim, right or action which the 
Company may have against the Executive or others.  In no event shall the 
Executive be obligated to seek other employment or take any other action by 
way of mitigation of the amounts payable to the Executive under any of the 
provisions of this Agreement and, except as provided in Section 6(a)(ii) of 
this Agreement, such amounts shall not be reduced whether or not the 
Executive obtains other employment.  If there is any contest by the Company 
concerning the Payments or benefits to be provided to the Executive hereunder 
whether through litigation, arbitration or mediation, or with respect to the 
validity or enforceability of, or liability under, any provision of this 
Agreement or any guarantee of performance thereof, and the Executive is the 
prevailing party, the Company agrees to pay promptly upon conclusion of the 
contest all legal fees and expenses which the Executive may reasonably have 
incurred.

              (b)    If there shall be any dispute between the Company and 
the Executive (i) in the event of any termination of the Executive's 
employment by the Company, whether such termination was for Cause, or (ii) in 
the event of any termination of employment by the Executive, whether Good 
Reason existed, then, unless and until there is a final, nonappealable 
judgment by a court of competent jurisdiction declaring that such termination 
was for Cause or that Good Reason did not exist, the Company shall pay all 
amounts, and provide all benefits, to the Executive and/or the Executive's 
family or other beneficiaries, as the case may be, that the Company would be 
required to pay or provide pursuant to Section 6(a) hereof as though such 
termination were by the Company without Cause or by the Executive with Good 
Reason; provided, however, that the Company shall not be required to pay any 
disputed amounts pursuant to this paragraph except upon receipt of an 
undertaking (which need not be secured) by or on behalf of the Executive to 
repay all such amounts to which the Executive is ultimately adjudged by such 
court not to be entitled.

       9.     CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.  (a) Anything in 
this Agreement to the contrary notwithstanding, in the event it shall be 
determined that any payment or distribution by the Company to or for the 
benefit of the Executive (whether paid or payable or distributed or 
distributable pursuant to the terms of this Agreement or otherwise, but 
determined without regard to any additional payments required under this 
Section 9) (a "Payment") would be subject to the excise tax imposed by 
Section 4999 of the Code or any interest or penalties are incurred by the 
Executive with respect to such excise tax (such excise tax, together with any 
such interest and penalties, are hereinafter collectively referred to as the 
"Excise Tax"), then the Executive shall be entitled to receive an additional 
payment (a "Gross-Up Payment") in an amount such that after payment by the 
Executive of all taxes (including any interest or penalties imposed with 
respect to such taxes), including, without limitation, any income taxes (and 
any interest and penalties imposed 

                                      -10-
<PAGE>

with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the 
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax 
imposed upon the Payments.

              (b)    Subject to the provisions of Section 9(c), all 
determinations required to be made under this Section 9, including whether 
and when Gross-Up Payment is required and the amount of such Gross-Up Payment 
and the assumptions to be utilized in arriving at such determination, shall 
be made by Arthur Andersen LLP (the "Accounting Firm") which shall provide 
detailed supporting calculations both to the Company and the Executive within 
15 business days of the receipt of notice from the Executive that there has 
been a Payment, or such earlier time as is requested by the Company.  In the 
event that the Accounting Firm is serving as accountant or auditor for the 
individual, entity or group effecting the Change of Control, the Executive 
shall appoint another nationally recognized accounting firm to make the 
determinations required hereunder (which accounting firm shall then be 
referred to as the Accounting Firm hereunder).  All fees and expenses of the 
Accounting Firm shall be borne solely by the Company.  Any Gross-Up Payment, 
as determined pursuant to this Section 9, shall be paid by the Company to the 
Executive within five days of the receipt of the Accounting Firm's 
determination.  If the Accounting Firm determines that no Excise Tax is 
payable by the Executive, it shall furnish the Executive with a written 
opinion that failure to report the Excise Tax on the Executive's applicable 
federal income tax return would not result in the imposition of a negligence 
or similar penalty.  Any determination by the Accounting Firm shall be 
binding upon the Company and the Executive.  As a result of the uncertainty 
in the application of Section 4999 of the Code at the time of the initial 
determination by the Accounting Firm hereunder, it is possible that Gross-Up 
Payments which will not have been made by the Company should have been made 
("Underpayment"), consistent with the calculations required to be made 
hereunder.  In the event that the Company exhausts its remedies pursuant to 
Section 9(c) and the Executive thereafter is required to make a payment of 
any Excise Tax, the Accounting Firm shall determine the amount of the 
Underpayment that has occurred and any such Underpayment shall be promptly 
paid by the Company to or for the benefit of the Executive.

              (c)    The Executive shall notify the Company in writing of any 
claims by the Internal Revenue Service that, if successful, would require the 
payment by the Company of the Gross-Up Payment.  Such notification shall be 
given as soon as practicable but no later than ten business days after the 
Executive is informed in writing of such claim and shall apprise the Company 
of the nature of such claim and the date on which such claim is requested to 
be paid.  The Executive shall not pay such claim prior to the expiration of 
the 30-day period following the date on which it gives such notice to the 
Company (or such shorter period ending on the date that any payment of taxes 
with respect to such claim is due).  If the Company notifies the Executive in 
writing prior to the expiration of such period that it desires to contest 
such claim, the Executive shall:

              (i)    give the Company any information reasonably requested by 
the Company relating to such claim,

              (ii)   take such action in connection with contesting such 
claim as the Company shall reasonably request in writing from time to time, 
including, without limitation, accepting legal representation with respect to 
such claim by an attorney reasonably selected by the Company,

                                      -11-
<PAGE>

              (iii)  cooperate with the Company in good faith in order 
effectively to contest such claim, and

              (iv)   permit the Company to participate in any proceedings 
relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and 
expenses (including additional interest and penalties) incurred in connection 
with such contest and shall indemnify and hold the Executive harmless, on an 
after-tax basis, for any Excise Tax or income tax (including interest and 
penalties with respect thereto) imposed as a result of such representation 
and payment of costs and expenses.  Without limitation on the foregoing 
provisions of this Section 9(c), the Company shall control all proceedings 
taken in connection with such contest and, at its sole option, may pursue or 
forego any and all administrative appeals, proceedings, hearings and 
conferences with the taxing authority in respect of such claim and may, at 
its sole option, either direct the Executive to pay the tax claimed and sue 
for a refund or contest the claim in any permissible manner, and the 
Executive agrees to prosecute such contest to a determination before any 
administrative tribunal, in a court of initial jurisdiction and in one or 
more appellate courts, as the Company shall determine; provided, however, 
that if the Company directs the Executive to pay such claim and sue for a 
refund, the Company shall advance the amount of such payment to the 
Executive, on an interest-free basis and shall indemnify and hold the 
Executive harmless, on an after-tax basis, from any Excise Tax or income tax 
(including interest or penalties with respect thereto) imposed with respect 
to such advance or with respect to any imputed income with respect to such 
advance; and further provided that any extension of the statute of 
limitations relating to payment of taxes for the taxable year of the 
Executive with respect to which such contested amount is claimed to be due is 
limited solely to such contested amount.  Furthermore, the Company's control 
of the contest shall be limited to issues with respect to which a Gross-Up 
Payment would be payable hereunder and the Executive shall be entitled to 
settle or contest, as the case may be, any other issue raised by the Internal 
Revenue Service or any other taxing authority.

              (d)    If, after the receipt by the Executive of an amount 
advanced by the Company pursuant to Section (c), the Executive becomes 
entitled to receive any refund with respect to such claim, the Executive 
shall (subject to the Company's complying with the requirements of Section 
9(c)) promptly pay to the Company the amount of such refund (together with 
any interest paid or credited thereon after taxes applicable thereto).  If, 
after the receipt by the Executive of an amount advanced by the Company 
pursuant to Section 9(c), a determination is made that the Executive shall 
not be entitled to any refund with respect to such claim and the Company does 
not notify the Executive in writing of its intent to contest such denial of 
refund prior to the expiration of 30 days after such determination, then such 
advance shall be forgiven and shall not be required to be repaid and the 
amount of such advance shall be offset, to the extent thereof, the amount of 
Gross-Up Payment required to be paid.

       10.    CONFIDENTIAL INFORMATION.  The Executive shall hold in a 
fiduciary capacity for the benefit of the Company all secret or confidential 
information, knowledge or data relating to the Company or any of its 
affiliated companies, and their respective businesses, which shall have been 
obtained by the Executive during the Executive's employment by the Company or 
any of its affiliated companies and which shall not be or become public 
knowledge (other than by acts by the Executive or representatives of the 
Executive in violation of this Agreement).  After termination of 

                                      -12-
<PAGE>

the Executive's employment with the Company, the Executive shall not, without 
the prior written consent of the Company or as may otherwise be required by 
law or legal process, communicate or divulge any such information, knowledge 
or data to anyone other than the Company and those designated by it.  In no 
event shall an asserted violation of the provisions of this Section 10 
constitute a basis for deferring or withholding any amounts otherwise payable 
to the Executive under this Agreement.

       11.    SUCCESSORS.  (a) This Agreement is personal to the Executive 
and without the prior written consent of the Company shall not be assignable 
by the Executive otherwise than by will or the laws of descent and 
distribution.  This Agreement shall inure to the benefit of and be 
enforceable by the Executive's legal representatives.  

              (b)    This Agreement shall inure to the benefit of and be 
binding upon the Company and its successors and assigns.  

              (c)    The Company will require any successor (whether direct 
or indirect, by purchase, merger, consolidation or otherwise) to all or 
substantially all of the business and/or assets of the Company to assume 
expressly and agree to perform this Agreement in the same manner and to the 
same extent that the Company would be required to perform it if no such 
succession had taken place.  As used in this Agreement, "Company" shall mean 
the Company as hereinbefore defined and any successor to its business and/or 
assets as aforesaid which assumes and agrees to perform this Agreement by 
operation of law, or otherwise.

       12.    MISCELLANEOUS.  (a) This Agreement shall be an unfunded 
obligation of the Company.

              (b)    THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN 
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REFERENCE TO 
PRINCIPLES OF CONFLICT OF LAWS.  The captions of this Agreement are not part 
of the provisions hereof and shall have no force or effect.  This Agreement 
may not be amended or modified otherwise than by a written agreement executed 
by the parties hereto or their respective successors and legal 
representatives.

              (c)    All notices and other communications hereunder shall be 
in writing and shall be given by hand delivery to the other party or by 
registered or certified mail, return receipt requested, postage prepaid,

                           EXECUTIVE EMPLOYMENT AGREEMENT


              AGREEMENT by and between POGO PRODUCING COMPANY, a Delaware
corporation (the "Company") and J. DON MCGREGOR (the "Executive"), dated as of
the 1st day of February, 1999.

              The Board of Directors of the Company (the "Board"), has
determined that it is in the best interests of the Company and its shareholders
to assure that the Company will have the continued dedication of the Executive,
and to provide the Executive with compensation and benefits arrangements which
are competitive with those of other corporations and which ensure that the
compensation and benefits expectations of the Executive will be satisfied.  The
Board also believes it is imperative to diminish the inevitable distraction of
the Executive by virtue of the personal uncertainties and risks created by a
pending or threatened Change of Control and to encourage the Executive's full
attention and dedication to the Company currently and in the event of any
threatened or pending Change of Control, and to insure the continuation of
favorable compensation and benefits upon a Change of Control.  Therefore, in
order to accomplish these objectives, the Board has caused the Company to enter
into this Agreement.

              NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS;

       1.     CERTAIN DEFINITIONS.  (a)  The "Effective Date" shall mean the
date of this Agreement.

              (b)  The "Employment Period" shall mean the period commencing on
the Effective Date and ending on the second anniversary of such date; provided,
however, that on each annual anniversary of the Effective Date (the "Renewal
Date"), the Employment Period shall be reviewed, to determine whether, in the
discretion of the Company, it should be extended for one additional year so as
to terminate two years from such Renewal Date.  Any such one year extension
shall be effective only if, prior to the Renewal Date, the Company shall give
notice to the Executive that the Employment Period shall be so extended.

       2.     CHANGE OF CONTROL.  For the purpose of this Agreement, a "Change
of Control" shall mean:

              (a)  The acquisition by any individual, entity or group (within
the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
1934, as amended (the "Exchange Act")) (a "Person") of beneficial ownership
(within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or
more of either (i) the then outstanding shares of common stock of the Company
(the "Outstanding Company Common Stock") or (ii) the combined voting power of
the then outstanding voting securities of the Company entitled to vote generally
in the election of directors (the "Outstanding Company Voting Securities").

<PAGE>

              Notwithstanding anything in this Agreement to the contrary, the
following shall not constitute a Change of Control:

              (i)    any acquisition directly from the Company (excluding an
acquisition by virtue of the exercise of a conversion privilege),

              (ii)   any acquisition by the Company,

              (iii)  any acquisition by any employee benefit plan (or related
trust) sponsored or maintained by the Company or any corporation controlled by
the Company, or

              (iv)   any acquisition by State Farm Mutual Automobile Insurance
Company and certain affiliates ("State Farm") or Klingenstein, Fields & Co.,
L.P. ("Klingenstein") ("Specified Stockholders") of beneficial ownership of
Outstanding Company Voting Securities resulting in an accumulation of said
securities up to and including the following amounts:

                     A.   In the case of State Farm, 30% of Outstanding Voting
Securities, and 

                     B.   In the case of Klingenstein, 30% of Outstanding
Voting Securities, or

              (v)    any acquisition by any corporation pursuant to a
reorganization, merger or consolidation, if, following such reorganization,
merger or consolidation, the conditions described in clauses (i), (ii) and (iii)
of subsection (c) of this Section 2 are satisfied; or 

              (b)    Individuals who, as of the date hereof, constitute the
Board (the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board; provided, however, that any individual becoming a
director subsequent to the date hereof whose election, or nomination for
election by the Company's shareholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board shall be
considered as though such individual were a member of the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of either an actual or threatened election contest (as
such terms are used in Rule 14a-11 of Regulation 14A promulgated under the
Exchange Act) or other actual or threatened solicitation of proxies or consents
by or on behalf of a Person other than the Board; or 

              (c)    Approval by the shareholders of the Company of a
reorganization, merger or consolidation, in each case, unless, following such
reorganization, merger or consolidation, (i) more than 60% of, respectively, the
then outstanding shares of common stock of the corporation resulting from such
reorganization, merger or consolidation and the combined voting power of the
then outstanding voting securities of such corporation entitled to vote

indirectly, by all or substantially all of the individuals and entities who

Stock and Outstanding Company Voting Securities immediately prior to such
reorganization, merger or consolidation in substantially the same proportions as
their ownership,

such corporation resulting from such reorganization, merger or consolidation

(iii) at least a majority of the members of the board of directors of the 
corporation resulting from such reorganization, merger or consolidation were 
members of the Incumbent Board at the time of the execution of the initial 
agreement providing for such reorganization, merger or consolidation; or

              (d)    Approval by the shareholders of the Company of (i) a
complete liquidation or dissolution of the Company or (ii) the sale or other
disposition of all or substantially all of the assets of the Company, other than
to a corporation with respect to which following such sale or other disposition

of such corporation and the combined voting power of the then outstanding voting
securities of such corporation entitled to vote generally in the election of
directors is then beneficially owned, directly or indirectly, by all or
substantially all of the individuals and entities who were the beneficial
owners, respectively, of the Outstanding Company Common Stock and Outstanding
Company Voting Securities immediately prior to such sale or other disposition in
substantially the same proportion as their ownership, immediately prior to such
sale or other disposition, of the Outstanding Company Common Stock and
Outstanding Company Voting Securities, as the case may be, (B) no Person
[excluding the Company, any Specified Stockholder, any employee benefit plan (or
related trust) of the Company or such corporation and any Person beneficially
owning, immediately prior to such sale or other disposition, directly or
indirectly, 20% or more of the Outstanding Company Common Stock or Outstanding
Company Voting Securities, as the case may be] beneficially owns, directly or
indirectly, 20% or more of, respectively, the then outstanding shares of common
stock of such corporation and the combined voting power of the then outstanding
voting securities of such corporation entitled to vote generally in the election
of directors and (C) at least a majority of the members of the board of
directors of such corporation where members of the Incumbent Board at the time
of the execution of the initial agreement or action of the Board providing for
such sale or other disposition of assets of the Company.  


       3.     EMPLOYMENT AGREEMENT.  The Company hereby agrees to continue the
Executive in its employ in accordance with the terms and provisions of this
Agreement, for the Employment Period.


       4.     TERMS OF EMPLOYMENT.  (a)  POSITION AND DUTIES.  (i) During the

those held, exercised and assigned at any time during the 90-day period
immediately preceding the later of the Effective Date, the most recent Renewal

publicly traded for profit business organized in other than corporate form
without the consent of the Compensation Committee of the Board of Directors of
the Company.  It is expressly understood and agreed that to the extent that any
such activities have been conducted by the Executive prior to the Applicable
Date, the continued conduct of such activities (or the conduct of activities
similar in nature and scope thereto) subsequent to the Applicable Date shall not
thereafter be deemed to interfere with the performance of the Executive's
responsibilities to the Company.

              (b)    COMPENSATION.  (i)   BASE SALARY.  During the Employment
Period, the Executive shall receive an annual base salary ("Annual Base
Salary"), which shall be paid on a monthly basis, at least equal to twelve times
the highest  monthly base salary paid or payable to the Executive by the Company
and its affiliated companies in respect of the twelve-month period immediately
preceding the month in which the Applicable Date occurs.  During the Employment
Period, the Annual Base Salary shall be reviewed at least annually and may be
increased at any time and from time to time as shall be substantially consistent
with increases in base salary generally awarded in the ordinary course of
business to other executives of the Company and its affiliated companies.  Any
increase in Annual Base Salary shall not serve to limit or reduce any other
obligation to the Executive under this Agreement.  As used in this Agreement,
the term "affiliated companies" shall include any company controlled by,
controlling or under common control with the Company.

                     (ii)   ANNUAL BONUS.  In addition to Annual Base Salary,
the Executive may be awarded at the discretion of the Company for any fiscal
year ending during the Employment Period, a bonus.  

                     (iii)  INCENTIVE, SAVINGS AND RETIREMENT PLANS.  During the
Employment Period, the Executive shall be entitled to participate in all
incentive, savings and retirement plans, practices, policies and programs
applicable generally to other executives of the Company and its affiliated
companies.  Such plans, practices, policies and programs shall provide the
Executive with incentive opportunities (measured with respect to both regular
and special incentive opportunities, to the extent, if any, that such
distinction is applicable), savings opportunities and retirement benefit
opportunities, in each case, equal to the most favorable of those provided by
the Company and its affiliated companies for the Executive under such plans,
practices, policies and programs as in effect at any time during the 90-day
period immediately preceding the Applicable Date.

                     (iv)   WELFARE BENEFIT PLANS.  During the Employment
Period, the Executive and/or the Executive's family, as the case may be, shall
be eligible for participation in and shall receive all benefits under welfare
benefit plans, practices, policies and programs provided by the Company and its
affiliated companies (including, without limitation, medical, prescription,
dental, disability, salary continuance, employee life, group life, accidental
death and travel accident insurance plans and programs) to the extent applicable
generally to other executives of the Company and its affiliated companies.  Such
plans, practices, policies and programs shall provide the Executive with
benefits which are equal, in the aggregate, to the most favorable of such plans,
practices, policies and programs in effect for the Executive at any time during
the 90-day period immediately preceding the Applicable Date.  

                     (v)    EXPENSES.  During the Employment Period, the
Executive shall be entitled to receive prompt reimbursement for all reasonable
expenses incurred by the Executive in accordance with the most favorable
policies, practices and procedures of the Company and its affiliated companies
in effect for the Executive at any time during the 90-day period immediately
preceding the Applicable Date.  

                     (vi)   FRINGE BENEFITS.  During the Employment Period, the
Executive shall be entitled to fringe benefits in accordance with the most
favorable plans, practices, programs and policies of the Company and its
affiliated companies in effect for the Executive at any time during the 90-day
period immediately preceding the Applicable Date.

                     (vii)  OFFICE AND SUPPORT STAFF.  During the Employment
Period, the Executive shall be entitled to an office or offices of a size and
with furnishings and other appointments, and to personal secretarial and other
assistance, at least equal to the most favorable of the foregoing provided to
the Executive by the Company and its affiliated companies at any time during the
90-day period immediately preceding the Applicable Date.

                     (viii) VACATION.  During the Employment Period, the
Executive shall be entitled to paid vacation in accordance with the most
favorable plans, policies, programs and practices of the Company and its
affiliated companies as in effect for the Executive at any time during the 
90-day period immediately preceding the Applicable Date.  

       5.     TERMINATION OF EMPLOYMENT.  (a)  DEATH OR DISABILITY.  The
Executive's employment shall terminate automatically upon the Executive's death
during the Employment Period.  If the Company determines in good faith that the
Disability of the Executive has occurred during the Employment Period (pursuant
to the definition of Disability set forth below), it may give to the Executive
written notice in accordance with Section 12(c) of this Agreement of its
intention to terminate the Executive's employment.  In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that, within the 30 days after such receipt, the Executive
shall not have returned to full-time performance of the Executive's duties.  For
purposes of this Agreement, "Disability" shall mean the absence of the Executive
from the Executive's duties with the Company on a full-time basis for 180
consecutive business days as a result of incapacity due to mental or physical
illness which is determined to be total and permanent by a physician selected by


                                     -5-
<PAGE>

the Company or its insurers and acceptable to the Executive or the Executive's
legal representative (such agreement as to acceptability not to be withheld
unreasonably).

              (b)    CAUSE.  The Company may terminate the Executive's
employment during the Employment Period for Cause.  For purposes of this
Agreement, "Cause" shall mean (i) a material violation by the Executive of the
Executive's obligations under Section 4(a) of this Agreement (other than as a
result of incapacity due to physical or mental illness) which is willful and
deliberate on the Executive's part, which is committed in bad faith or without
reasonable belief that such violation is in the best interests of the Company
and which is not remedied in a reasonable period of time after receipt of
written notice from the Company specifying such violation or (ii) the conviction
of the Executive of a felony involving moral turpitude.

              (c)    GOOD REASON; WINDOW PERIOD; OTHER TERMINATIONS.  The
Executive's employment may be terminated (i) during the Employment Period by the
Executive for Good Reason, (ii) during the Window Period by the Executive
without any reason or (iii) by Executive other than (A) for Good Reason or (B)
during a Window Period.

              For purposes of this Agreement, the "Window Period" shall mean the
180-day period immediately following the date a Change of Control occurs. 
Anything in this Agreement to the contrary notwithstanding, if a Change of
Control occurs and if the Executive's employment with the Company is terminated
prior to the date on which the Change of Control occurs, and if it is reasonably
demonstrated by the Executive that such termination of employment or cessation
of status as an officer (i) was at the request of a third party who has taken
steps reasonably calculated to effect the Change of Control or (ii) otherwise
arose in connection with or anticipation of the Change of Control, then for all
purposes of this Agreement the "date a Change of Control occurs" shall mean the
date immediately prior to the date of such termination of employment or
cessation of status as an officer.

              For purposes of this Agreement, "Good Reason" shall mean

              (i)    the assignment to the Executive of any duties inconsistent
with the Executive's position (including status, offices, titles and reporting
requirements), authority, duties or responsibilities as contemplated by
Section 4(a) of this Agreement, or any other action by the Company which results
in a diminution in such position, authority, duties or responsibilities
excluding for this purpose an insubstantial or inadvertent action which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive;

              (ii)   any failure by the Company to comply with any of the
provisions of Section 4(b) of this Agreement, other than an insubstantial or
inadvertent failure which is remedied by the Company promptly after receipt of
notice thereof given by the Executive;

              (iii)  the Company's requiring the Executive to be based at any
office or location other than that described in Section 4(a)(i)(B) hereof;  

              (iv)  any purported termination by the Company of the Executive's
employment otherwise than as expressly permitted by this Agreement; or 


                                     -6-
<PAGE>

              (v)    any failure by the Company to comply with and satisfy
Section 11(c) of this Agreement.

              (d)    NOTICE OF TERMINATION.  Any termination by the Company for
Cause, or by the Executive without any reason during the Window Period or for
Good Reason, shall be communicated by Notice of Termination to the other party
hereto given in accordance with Section 12(c) of this Agreement.  For purposes
of this Agreement, a "Notice of Termination" means a written notice which
(i) indicates the specific termination provision in this Agreement relied upon,
(ii) to the extent applicable, sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated and (iii) if the Date of Termination
(as defined below) is other than the date of receipt of such notice, specifies
the termination date (which date shall be not more than fifteen days after the
giving of such notice).  The failure by the Executive or the Company to set
forth in the Notice of Termination any fact or circumstance which contributes to
a showing of Good Reason or Cause shall not waive any right of the Executive or
the Company hereunder or preclude the Executive or the Company from asserting
such fact or circumstance in enforcing the Executive's or the Company's right
hereunder.

              (e)    DATE OF TERMINATION.  "Date of Termination" means (i) if
the Executive's employment is terminated by the Company for Cause, or by the
Executive during the Window Period or for Good Reason, the date of receipt of
the Notice of Termination or any later date specified therein, as the case may
be, (ii) if the Executive's employment is terminated by the Company other than
for Cause or Disability, the Date of Termination shall be the date on which the
Company notifies the Executive of such termination, (iii) if the Executive's
employment is terminated by reason of death or Disability, the Date of
Termination shall be the date of death of the Executive or the Disability
Effective Date, as the case may be, and (iv) if the Executive's employment is
terminated by the Executive other than for Good Reason or during a Window
Period, the date of the receipt of the Notice of Termination or any later date
specified therein.  

              6.     OBLIGATIONS OF THE COMPANY UPON TERMINATION.

              (a)    GOOD REASON OR DURING THE WINDOW PERIOD; OTHER THAN FOR
CAUSE, DEATH OR DISABILITY.  If, during the Employment Period, the Company shall
terminate the Executive's employment other than for Cause or Disability or the
Executive shall terminate employment either for Good Reason or without any
reason during the Window Period:

              (i)    the Company shall pay to the Executive in a lump sum in
cash within 30 days after the Date of Termination the aggregate of the following
amounts:

                     A.  the sum of (1) the Executive's Annual Base Salary
through the Date of Termination to the extent not theretofore paid and (2) any
compensation previously deferred by the Executive (together with any accrued
interest or earnings thereon) and any accrued vacation pay, in each case to the
extent not theretofore paid (the sum of the amounts described in clauses (1) and
(2) shall be hereinafter referred to as the "Accrued Obligations"); and 


                                     -7-
<PAGE>

                     B.  the amount (such amount shall be hereinafter referred
to as the "Severance Amount") equal to the product of (1) three and (2) the sum
of (x) the Executive's Annual Base Salary and (y) any bonus described in Section
4(b)(ii) paid or payable in respect of the most recently completed fiscal year
of the Company; and, provided further, that such amount shall be reduced by the
present value (determined as provided in Section 280G(d)(4) of the Internal
Revenue Code of 1986, as amended (the "Code")) of any other amount of severance
relating to salary or bonus continuation to be received by the Executive upon
termination of employment of the Executive under any severance plan, severance
policy or severance arrangement of the Company; and 

                     C.  a separate lump sum supplemental retirement benefit
equal to the difference between (1) the actuarial equivalent (utilizing for this
purpose the actuarial assumptions utilized with respect to the Employees
Retirement Plan for Pogo Producing Company (or any successor plan thereto) (the
"Retirement Plan") during the 90-day period immediately preceding the Applicable
Date) of the benefit payable under the Retirement Plan and any supplemental
and/or excess retirement plan of the Company and its affiliated companies
providing benefits for the Executive (the "SERP") which the Executive would
receive if the Executive's employment continued at the compensation level
provided for in Sections 4(b)(i) and 4(b)(ii) of this Agreement for the
remainder of the Employment Period, assuming for this purpose that all accrued
benefits are fully vested and that benefit accrual formulas are no less
advantageous to the Executive than those in effect during the 90-day period
immediately preceding the Applicable Date, and (2) the actuarial equivalent
(utilizing for this purpose the actuarial assumptions utilized with respect to
the Retirement Plan during the 90-day period immediately preceding the
Applicable Date) of the Executive's actual benefit (paid or payable), if any,
under the Retirement Plan and the SERP (the amount of such benefit shall be
hereinafter referred to as the "Supplemental Retirement Amount"); and 

              (ii)   for the remainder of the Employment Period, or such longer
period as any plan, program, practice or policy may provide, the Company shall
continue benefits to the Executive and/or the Executive's family at least equal
to those which would have been provided to them in accordance with the plans,
programs, practices and policies described in Section 4(b)(iv) of this Agreement
if the Executive's employment had not been terminated in accordance with the
most favorable plans, practices, programs or policies of the Company and its
affiliated companies as in effect and applicable generally to other executives
and their families during the 90-day period immediately preceding the Applicable
Date, provided, however, that if the Executive becomes reemployed with another
employer and is eligible to receive medical or other welfare benefits under
another employer provided plan, the medical and other welfare benefits described
herein shall be secondary to those provided under such other plan during such
applicable period of eligibility (such continuation of such benefits for the
applicable period herein set forth shall be hereinafter referred to as "Welfare
Benefit Continuation").  For purposes of determining eligibility of the
Executive for retiree benefits pursuant to such plans, practices, programs and
policies, the Executive shall be considered to have remained employed until the
end of the Employment Period and to have retired on the last day of such period;
and 

              (iii)  to the extent not theretofore paid or provided, the Company
shall timely pay or provide to the Executive and/or the Executive's family any
other amounts or benefits required to 


                                     -8-
<PAGE>

be paid or provided or which the Executive and/or the Executive's family is 
eligible to receive pursuant to this Agreement and under any plan, program, 
policy or practice or contract or agreement of the Company and its affiliated 
companies as in effect and applicable generally to other executives and their 
families during the 90-day period immediately preceding the Applicable Date 
(such other amounts and benefits shall be hereinafter referred to as the 
"Other Benefits").  

              (b)    DEATH.  If the Executive's employment is terminated by
reason of the Executive's death during the Employment Period, this Agreement
shall terminate without further obligations to the Executive's legal
representatives under this Agreement, other than for (i) payment of Accrued
Obligations (which shall be paid to the Executive's estate or beneficiary, as
applicable, in a lump sum in cash within 30 days of the Date of Termination) and
the timely payment or provision of the Welfare Benefit Continuation and Other
Benefits and (ii) payment to the Executive's estate or beneficiary, as
applicable, in a lump sum in cash within 30 days of the Date of Termination of
an amount equal to the sum of the Severance Amount and the Supplemental
Retirement Amount.

              (c)    DISABILITY.  If the Executive's employment is terminated by
reason of the Executive's Disability during the Employment Period, this
Agreement shall terminate without further obligations to the Executive, other
than for (i) payment of Accrued Obligations (which shall be paid to the
Executive in a lump sum in cash within 30 days of the Date of Termination) and
the timely payment or provision of the Welfare Benefit Continuation and Other
Benefits (excluding, in each case, Disability Benefits (as defined below)) and
(ii) payment to the Executive in a lump sum in cash within 30 days of the Date
of Termination of an amount equal to the greater of (A) the sum of the Severance
Amount and the Supplemental Retirement Amount and (B) the present value
(determined as provided in Section 280G(d)(4) of the Code) of any cash amount to
be received by the Executive as a disability benefit pursuant to the terms of
any long term disability plan, policy or arrangement of the Company and its
affiliated companies, but not including any proceeds of disability insurance
covering the Executive to the extent paid for on a contributory basis by the
Executive (which shall be paid in any event as an Other Benefit) (the benefits
included in this clause (B) shall be hereinafter referred to as the "Disability
Benefits").

              (d)    CAUSE; BY EXECUTIVE OTHER THAN FOR GOOD REASON AND OTHER
THAN DURING A WINDOW PERIOD.  If the Executive's employment shall be terminated
for Cause during the Employment Period, this Agreement shall terminate without
further obligations to the Executive other than the obligation to pay to the
Executive Annual Base Salary through the Date of Termination plus the amount of
any compensation previously deferred by the Executive, in each case to the
extent theretofore unpaid.  If the Executive terminates employment during the
Employment Period, excluding a termination either for Good Reason or without any
reason during the Window Period, this Agreement shall terminate without further
obligations to the Executive, other than for Accrued Obligations and the timely
payment or provision of Other Benefits.  In such case, all Accrued Obligations
shall be paid to the Executive in a lump sum in cash within 30 days of the Date
of Termination.

       7.     NON-EXCLUSIVITY OF RIGHTS.  Except as provided in
Section 6(a)(ii), 6(b) and 6(c) of this Agreement, nothing in this Agreement
shall prevent or limit the Executive's continuing or future participation in any
plan, program, policy or practice provided by the Company or any of its


                                     -9-
<PAGE>

affiliated companies and for which the Executive may qualify, nor shall anything
herein limit or otherwise affect such rights as the Executive may have under any
contract or agreement with the Company or any of its affiliated companies. 
Amounts which are vested benefits or which the Executive is otherwise entitled
to receive under any plan, policy, practice or program of or any contract or
agreement with the Company or any of its affiliated companies at or subsequent
to the Date of Termination shall be payable in accordance with such plan,
policy, practice or program or contract or agreement except as explicitly
modified by this Agreement.

       8.     FULL SETTLEMENT; RESOLUTION OF DISPUTES.  (a) The Company's
obligation to make payments provided for in this Agreement and otherwise to
perform its obligations hereunder shall not be affected by any set-off,
counterclaim, recoupment, defense or other claim, right or action which the
Company may have against the Executive or others.  In no event shall the
Executive be obligated to seek other employment or take any other action by way
of mitigation of the amounts payable to the Executive under any of the
provisions of this Agreement and, except as provided in Section 6(a)(ii) of this
Agreement, such amounts shall not be reduced whether or not the Executive
obtains other employment.  If there is any contest by the Company concerning the
Payments or benefits to be provided to the Executive hereunder whether through
litigation, arbitration or mediation, or with respect to the validity or
enforceability of, or liability under, any provision of this Agreement or any
guarantee of performance thereof, and the Executive is the prevailing party, the
Company agrees to pay promptly upon conclusion of the contest all legal fees and
expenses which the Executive may reasonably have incurred.

              (b)    If there shall be any dispute between the Company and the
Executive (i) in the event of any termination of the Executive's employment by
the Company, whether such termination was for Cause, or (ii) in the event of any
termination of employment by the Executive, whether Good Reason existed, then,
unless and until there is a final, nonappealable judgment by a court of
competent jurisdiction declaring that such termination was for Cause or that
Good Reason did not exist, the Company shall pay all amounts, and provide all
benefits, to the Executive and/or the Executive's family or other beneficiaries,
as the case may be, that the Company would be required to pay or provide
pursuant to Section 6(a) hereof as though such termination were by the Company
without Cause or by the Executive with Good Reason; provided, however, that the
Company shall not be required to pay any disputed amounts pursuant to this
paragraph except upon receipt of an undertaking (which need not be secured) by
or on behalf of the Executive to repay all such amounts to which the Executive
is ultimately adjudged by such court not to be entitled.

       9.     CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.  (a) Anything in this
Agreement to the contrary notwithstanding, in the event it shall be determined
that any payment or distribution by the Company to or for the benefit of the
Executive (whether paid or payable or distributed or distributable pursuant to
the terms of this Agreement or otherwise, but determined without regard to any
additional payments required under this Section 9) (a "Payment") would be
subject to the excise tax imposed by Section 4999 of the Code or any interest or
penalties are incurred by the Executive with respect to such excise tax (such
excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then the Executive shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including, without limitation,
any income taxes (and any interest and penalties imposed 


                                    -10-
<PAGE>

with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the 
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax 
imposed upon the Payments.

              (b)    Subject to the provisions of Section 9(c), all
determinations required to be made under this Section 9, including whether and
when Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination, shall be made
by Arthur Andersen LLP (the "Accounting Firm") which shall provide detailed
supporting calculations both to the Company and the Executive within 15 business
days of the receipt of notice from the Executive that there has been a Payment,
or such earlier time as is requested by the Company.  In the event that the
Accounting Firm is serving as accountant or auditor for the individual, entity
or group effecting the Change of Control, the Executive shall appoint another
nationally recognized accounting firm to make the determinations required
hereunder (which accounting firm shall then be referred to as the Accounting
Firm hereunder).  All fees and expenses of the Accounting Firm shall be borne
solely by the Company.  Any Gross-Up Payment, as determined pursuant to this
Section 9, shall be paid by the Company to the Executive within five days of the
receipt of the Accounting Firm's determination.  If the Accounting Firm
determines that no Excise Tax is payable by the Executive, it shall furnish the
Executive with a written opinion that failure to report the Excise Tax on the
Executive's applicable federal income tax return would not result in the
imposition of a negligence or similar penalty.  Any determination by the
Accounting Firm shall be binding upon the Company and the Executive.  As a
result of the uncertainty in the application of Section 4999 of the Code at the
time of the initial determination by the Accounting Firm hereunder, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made ("Underpayment"), consistent with the calculations
required to be made hereunder.  In the event that the Company exhausts its
remedies pursuant to Section 9(c) and the Executive thereafter is required to
make a payment of any Excise Tax, the Accounting Firm shall determine the amount
of the Underpayment that has occurred and any such Underpayment shall be
promptly paid by the Company to or for the benefit of the Executive.

              (c)    The Executive shall notify the Company in writing of any
claims by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment.  Such notification shall be
given as soon as practicable but no later than ten business days after the
Executive is informed in writing of such claim and shall apprise the Company of
the nature of such claim and the date on which such claim is requested to be
paid.  The Executive shall not pay such claim prior to the expiration of the
30-day period following the date on which it gives such notice to the Company
(or such shorter period ending on the date that any payment of taxes with
respect to such claim is due).  If the Company notifies the Executive in writing
prior to the expiration of such period that it desires to contest such claim,
the Executive shall:

              (i)    give the Company any information reasonably requested by
the Company relating to such claim,

              (ii)   take such action in connection with contesting such claim
as the Company shall reasonably request in writing from time to time, including,
without limitation, accepting legal representation with respect to such claim by
an attorney reasonably selected by the Company,


                                    -11-
<PAGE>

              (iii)  cooperate with the Company in good faith in order
effectively to contest such claim, and

              (iv)   permit the Company to participate in any proceedings
relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses.  Without limitation on the foregoing provisions
of this Section 9(c), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct the Executive to pay the tax claimed and sue for a refund or contest the
claim in any permissible manner, and the Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further provided that any extension of the statute of limitations relating
to payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount.  Furthermore, the Company's control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issue raised by the Internal Revenue Service or any other taxing
authority.

              (d)    If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section (c), the Executive becomes entitled
to receive any refund with respect to such claim, the Executive shall (subject
to the Company's complying with the requirements of Section 9(c)) promptly pay
to the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto).  If, after the receipt by the
Executive of an amount advanced by the Company pursuant to Section 9(c), a
determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund prior to the expiration
of 30 days after such determination, then such advance shall be forgiven and
shall not be required to be repaid and the amount of such advance shall be
offset, to the extent thereof, the amount of Gross-Up Payment required to be
paid.

       10.    CONFIDENTIAL INFORMATION.  The Executive shall hold in a fiduciary
capacity for the benefit of the Company all secret or confidential information,
knowledge or data relating to the Company or any of its affiliated companies,
and their respective businesses, which shall have been obtained by the Executive
during the Executive's employment by the Company or any of its affiliated
companies and which shall not be or become public knowledge (other than by acts

                           EXECUTIVE EMPLOYMENT AGREEMENT




          AGREEMENT by and between POGO PRODUCING COMPANY, a Delaware 
corporation (the "Company") and GERALD A. MORTON  (the "Executive"), dated as 
of the 1st day of February, 1999.

         The Board of Directors of the Company (the "Board"), has determined 
that it is in the best interests of the Company and its shareholders to 
assure that the Company will have the continued dedication of the Executive, 
and to provide the Executive with compensation and benefits arrangements 
which are competitive with those of other corporations and which ensure that 
the compensation and benefits expectations of the Executive will be 
satisfied.  The Board also believes it is imperative to diminish the 
inevitable distraction of the Executive by virtue of the personal 
uncertainties and risks created by a pending or threatened Change of Control 
and to encourage the Executive's full attention and dedication to the Company 
currently and in the event of any threatened or pending Change of Control, 
and to insure the continuation of favorable compensation and benefits upon a 
Change of Control.  Therefore, in order to accomplish these objectives, the 
Board has caused the Company to enter into this Agreement.

          NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS;


     1.   CERTAIN DEFINITIONS.  (a)  The "Effective Date" shall mean the
date of this Agreement.


          (b)   The "Employment Period" shall mean the period commencing on
the Effective Date and ending on the second anniversary of such date; provided,
however, that on each annual anniversary of the Effective Date (the "Renewal
Date"), the Employment Period shall be reviewed, to determine whether, in the
discretion of the Company, it should be extended for one additional year so as
to terminate two years from such Renewal Date.  Any such one year extension
shall be effective only if, prior to the Renewal Date, the Company shall give
notice to the Executive that the Employment Period shall be so extended.


     2.   CHANGE OF CONTROL.  For the purpose of this Agreement, a "Change
of Control" shall mean:


          (a)   The acquisition by any individual, entity or group (within
the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
1934, as amended (the "Exchange Act")) (a "Person") of beneficial ownership
(within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or
more of either (i) the then outstanding shares of common stock of the Company
(the "Outstanding Company Common Stock") or (ii) the combined voting power of
the then outstanding voting securities of the Company entitled to vote generally
in the election of directors (the "Outstanding Company Voting Securities").

<PAGE>

          Notwithstanding anything in this Agreement to the contrary, the 
following shall not constitute a Change of Control:

          (i)    any acquisition directly from the Company (excluding an
acquisition by virtue of the exercise of a conversion privilege),

          (ii)   any acquisition by the Company,

          (iii)  any acquisition by any employee benefit plan (or related
trust) sponsored or maintained by the Company or any corporation controlled by
the Company, or

          (iv)   any acquisition by State Farm Mutual Automobile Insurance
Company and certain affiliates ("State Farm") or Klingenstein, Fields & Co.,
L.P. ("Klingenstein") ("Specified Stockholders") of beneficial ownership of
Outstanding Company Voting Securities resulting in an accumulation of said
securities up to and including the following amounts:


                 A.   In the case of State Farm, 30% of Outstanding Voting
Securities, and 


                 B.   In the case of Klingenstein, 30% of Outstanding
Voting Securities, or


          (v)    any acquisition by any corporation pursuant to a 
reorganization, merger or consolidation, if, following such reorganization, 
merger or consolidation, the conditions described in clauses (i), (ii) and 
(iii) of subsection (c) of this Section 2 are satisfied; or 

          (b)    Individuals who, as of the date hereof, constitute the
Board (the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board; provided, however, that any individual becoming a
director subsequent to the date hereof whose election, or nomination for
election by the Company's shareholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board shall be
considered as though such individual were a member of the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of either an actual or threatened election contest (as
such terms are used in Rule 14a-11 of Regulation 14A promulgated under the
Exchange Act) or other actual or threatened solicitation of proxies or consents
by or on behalf of a Person other than the Board; or 


          (c)    Approval by the shareholders of the Company of a
reorganization, merger or consolidation, in each case, unless, following such
reorganization, merger or consolidation, (i) more than 60% of, respectively, the
then outstanding shares of common stock of the corporation resulting from such
reorganization, merger or consolidation and the combined voting power of the
then outstanding voting securities of such corporation entitled to vote

directors of such corporation where members of the Incumbent Board at the time

     3.   EMPLOYMENT AGREEMENT.  The Company hereby agrees to continue the
Executive in its employ in accordance with the terms and provisions of this
Agreement, for the Employment Period.


     4.   TERMS OF EMPLOYMENT.  (a)  POSITION AND DUTIES.  (i) During the
Employment Period, (A) the Executive's position (including status, offices,
titles and reporting requirements), authority, duties and responsibilities shall
be at least commensurate in all material respects with the most significant of
those held, exercised and assigned at any time during the 90-day period
immediately preceding the later of the Effective Date, the most recent Renewal
Date or a Change of Control, if any, (the "Applicable Date") and (B) the
Executive's services shall be performed at the 


                                     -3-
<PAGE>

location where the Executive was employed immediately preceding the 
Applicable Date or any office which is the headquarters of the Company and is 
less than 35 miles from such location.

               (ii)   During the Employment Period, and excluding any periods 
of vacation and sick leave to which the Executive is entitled, the Executive 
agrees to devote reasonable attention and time during normal business hours 
to the business and affairs of the Company.  During the Employment Period it 
shall not be a violation of this Agreement for the Executive to (A) serve on 
corporate, civic or charitable boards or committees, (B) deliver lectures, 
fulfill speaking engagements or teach at educational institutions and (C) 
manage personal investments, so long as such activities do not significantly 
interfere with the performance of the Executive's responsibilities as an 
employee of the Company in accordance with this Agreement; provided Executive 
may not serve on the board of a publicly traded for profit corporation or 
similar body of a publicly traded for profit business organized in other than 
corporate form without the consent of the Compensation Committee of the Board 
of Directors of the Company.  It is expressly understood and agreed that to 
the extent that any such activities have been conducted by the Executive 
prior to the Applicable Date, the continued conduct of such activities (or 
the conduct of activities similar in nature and scope thereto) subsequent to 
the Applicable Date shall not thereafter be deemed to interfere with the 
performance of the Executive's responsibilities to the Company.

          (b)  COMPENSATION. (i)   BASE SALARY.  During the Employment

and its affiliated companies in respect of the twelve-month period immediately
preceding the month in which the Applicable Date occurs.  During the Employment
Period, the Annual Base Salary shall be reviewed at least annually and may be
increased at any time and from time to time as shall be substantially consistent
with increases in base salary generally awarded in the ordinary course of
business to other executives of the Company and its affiliated companies.  Any
increase in Annual Base Salary shall not serve to limit or reduce any other
obligation to the Executive under this Agreement.  As used in this Agreement,
the term "affiliated companies" shall include any company controlled by,
controlling or under common control with the Company.

               (ii)   ANNUAL BONUS.  In addition to Annual Base Salary,

and special incentive opportunities, to the extent, if any, that such
distinction is applicable), savings opportunities and retirement benefit
opportunities, in each case, equal to the most favorable of those provided by
the Company and its affiliated companies for the Executive under such plans,

its affiliated companies (including, without limitation, medical, 
prescription, dental, disability, salary continuance, employee life, group 
life, accidental death and travel accident insurance plans and programs) to 
the extent applicable generally to other executives of the Company and its 
affiliated companies.  Such plans, practices, policies and programs shall 
provide the Executive with benefits which are equal, in the aggregate, to the 
most favorable of such plans, practices, policies and programs in effect for 
the Executive at any time during the 90-day period immediately preceding the 
Applicable Date.  

               (v)    EXPENSES.  During the Employment Period, the Executive

Period, the Executive shall be entitled to an office or offices of a size and 
with furnishings and other appointments, and to personal secretarial and 
other assistance, at least equal to the most favorable of the foregoing

               (viii) VACATION.  During the Employment Period, the Executive

immediately preceding the Applicable Date.  

     5.   TERMINATION OF EMPLOYMENT.  (a)  DEATH OR DISABILITY.  The
Executive's employment shall terminate automatically upon the Executive's death
during the Employment Period.  If the Company determines in good faith that the
Disability of the Executive has occurred during the Employment Period (pursuant
to the definition of Disability set forth below), it may give to the Executive
written notice in accordance with Section 12(c) of this Agreement of its
intention to terminate the Executive's employment.  In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that, within the 30 days after such receipt, the Executive
shall not have returned to full-time performance of the Executive's duties.  For
purposes of this Agreement, "Disability" shall mean the absence of the Executive
from the Executive's duties with the Company on a full-time basis for 180
consecutive business days as a result of incapacity due to mental or physical
illness which is determined to be total and permanent by a physician selected by


                                     -5-
<PAGE>

the Company or its insurers and acceptable to the Executive or the Executive's
legal representative (such agreement as to acceptability not to be withheld
unreasonably).

          (b)    CAUSE.  The Company may terminate the Executive's employment 
during the Employment Period for Cause.  For purposes of this Agreement, 
"Cause" shall mean (i) a material violation by the Executive of the 
Executive's obligations under Section 4(a) of this Agreement (other than as a 
result of incapacity due to physical or mental illness) which is willful and 
deliberate on the Executive's part, which is committed in bad faith or 
without reasonable belief that such violation is in the best interests of the 
Company and which is not remedied in a reasonable period of time after 
receipt of written notice from the Company specifying such violation or (ii) 
the conviction of the Executive of a felony involving moral turpitude.

          (c)    GOOD REASON; WINDOW PERIOD; OTHER TERMINATIONS.  The 
Executive's employment may be terminated (i) during the Employment Period by 
the Executive for Good Reason, (ii) during the Window Period by the Executive 
without any reason or (iii) by Executive other than (A) for Good Reason or 
(B) during a Window Period.

          For purposes of this Agreement, the "Window Period" shall mean the 
180-day period immediately following the date a Change of Control occurs. 
Anything in this Agreement to the contrary notwithstanding, if a Change of 
Control occurs and if the Executive's employment with the Company is 
terminated prior to the date on which the Change of Control occurs, and if it 
is reasonably demonstrated by the Executive that such termination of 
employment or cessation of status as an officer (i) was at the request of a 
third party who has taken steps reasonably calculated to effect the Change of 
Control or (ii) otherwise arose in connection with or anticipation of the 
Change of Control, then for all purposes of this Agreement the "date a Change 
of Control occurs" shall mean the date immediately prior to the date of such 
termination of employment or cessation of status as an officer.

          For purposes of this Agreement, "Good Reason" shall mean


          (i)    the assignment to the Executive of any duties inconsistent
with the Executive's position (including status, offices, titles and reporting
requirements), authority, duties or responsibilities as contemplated by
Section 4(a) of this Agreement, or any other action by the Company which results
in a diminution in such position, authority, duties or responsibilities
excluding for this purpose an insubstantial or inadvertent action which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive;

          (ii)   any failure by the Company to comply with any of the
provisions of Section 4(b) of this Agreement, other than an insubstantial or
inadvertent failure which is remedied by the Company promptly after receipt of
notice thereof given by the Executive;


          (iii)  the Company's requiring the Executive to be based at any
office or location other than that described in Section 4(a)(i)(B) hereof;  


          (iv)   any purported termination by the Company of the Executive's
employment otherwise than as expressly permitted by this Agreement; or 


                                     -6-
<PAGE>

          (v)    any failure by the Company to comply with and satisfy
Section 11(c) of this Agreement.


          (d)    NOTICE OF TERMINATION.  Any termination by the Company for
Cause, or by the Executive without any reason during the Window Period or for
Good Reason, shall be communicated by Notice of Termination to the other party
hereto given in accordance with Section 12(c) of this Agreement.  For purposes
of this Agreement, a "Notice of Termination" means a written notice which
(i) indicates the specific termination provision in this Agreement relied upon,
(ii) to the extent applicable, sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated and (iii) if the Date of Termination
(as defined below) is other than the date of receipt of such notice, specifies
the termination date (which date shall be not more than fifteen days after the
giving of such notice).  The failure by the Executive or the Company to set
forth in the Notice of Termination any fact or circumstance which contributes to
a showing of Good Reason or Cause shall not waive any right of the Executive or
the Company hereunder or preclude the Executive or the Company from asserting
such fact or circumstance in enforcing the Executive's or the Company's right
hereunder.

          (e)    DATE OF TERMINATION.  "Date of Termination" means (i) if
the Executive's employment is terminated by the Company for Cause, or by the
Executive during the Window Period or for Good Reason, the date of receipt of
the Notice of Termination or any later date specified therein, as the case may
be, (ii) if the Executive's employment is terminated by the Company other than
for Cause or Disability, the Date of Termination shall be the date on which the
Company notifies the Executive of such termination, (iii) if the Executive's
employment is terminated by reason of death or Disability, the Date of
Termination shall be the date of death of the Executive or the Disability
Effective Date, as the case may be, and (iv) if the Executive's employment is
terminated by the Executive other than for Good Reason or during a Window
Period, the date of the receipt of the Notice of Termination or any later date
specified therein.  

          6.     OBLIGATIONS OF THE COMPANY UPON TERMINATION.

          (a)    GOOD REASON OR DURING THE WINDOW PERIOD; OTHER THAN FOR 
CAUSE, DEATH OR DISABILITY.  If, during the Employment Period, the Company 
shall terminate the Executive's employment other than for Cause or Disability 
or the Executive shall terminate employment either for Good Reason or without 
any reason during the Window Period:

          (i)    the Company shall pay to the Executive in a lump sum in
cash within 30 days after the Date of Termination the aggregate of the following
amounts:

                 A.  the sum of (1) the Executive's Annual Base Salary 
through the Date of Termination to the extent not theretofore paid and (2) 
any compensation previously deferred by the Executive (together with any 
accrued interest or earnings thereon) and any accrued vacation pay, in each 
case to the extent not theretofore paid (the sum of the amounts described in 
clauses (1) and (2) shall be hereinafter referred to as the "Accrued 
Obligations"); and 


                                     -7-

as the "Severance Amount") equal to the product of (1) three and (2) the sum 
of (x) the Executive's Annual Base Salary and (y) any bonus described in 
Section 4(b)(ii) paid or payable in respect of the most recently completed 
fiscal year of the Company; and, provided further, that such amount shall be 
reduced by the present value (determined as provided in Section 280G(d)(4) of 
the Internal Revenue Code of 1986, as amended (the "Code")) of any other 
amount of severance relating to salary or bonus continuation to be received 
by the Executive upon termination of employment of the Executive under any 
severance plan, severance policy or severance arrangement of the Company; and 

                 C.  a separate lump sum supplemental retirement benefit 
equal to the difference between (1) the actuarial equivalent (utilizing for 
this purpose the actuarial assumptions utilized with respect to the Employees 
Retirement Plan for Pogo Producing Company (or any successor plan thereto)

Applicable Date) of the benefit payable under the Retirement Plan and any 
supplemental and/or excess retirement plan of the Company and its affiliated 
companies providing benefits for the Executive (the "SERP") which the 
Executive would receive if the Executive's employment continued at the 
compensation level provided for in Sections 4(b)(i) and 4(b)(ii) of this 
Agreement for the remainder of the Employment Period, assuming for this 
purpose that all accrued benefits are fully vested and that benefit accrual 
formulas are no less advantageous to the Executive than those in effect 
during the 90-day period immediately preceding the Applicable Date, and (2) 
the actuarial equivalent (utilizing for this purpose the actuarial 
assumptions utilized with respect to the Retirement Plan during the 90-day 
period immediately preceding the Applicable Date) of the Executive's actual 
benefit (paid or payable), if any, under the Retirement Plan and the SERP 
(the amount of such benefit shall be hereinafter referred to as the 
"Supplemental Retirement Amount"); and 

          (ii)   for the remainder of the Employment Period, or such longer
period as any plan, program, practice or policy may provide, the Company shall
continue benefits to the Executive and/or the Executive's family at least equal
to those which would have been provided to them in accordance with the plans,
programs, practices and policies described in Section 4(b)(iv) of this Agreement
if the Executive's employment had not been terminated in accordance with the
most favorable plans, practices, programs or policies of the Company and its
affiliated companies as in effect and applicable generally to other executives
and their families during the 90-day period immediately preceding the Applicable
Date, provided, however, that if the Executive becomes reemployed with another
employer and is eligible to receive medical or other welfare benefits under
another employer provided plan, the medical and other welfare benefits described
herein shall be secondary to those provided under such other plan during such
applicable period of eligibility (such continuation of such benefits for the
applicable period herein set forth shall be hereinafter referred to as "Welfare
Benefit Continuation").  For purposes of determining eligibility of the
Executive for retiree benefits pursuant to such plans, practices, programs and
policies, the Executive shall be considered to have remained employed until the
end of the Employment Period and to have retired on the last day of such period;
and 

          (iii)  to the extent not theretofore paid or provided, the Company
shall timely pay or provide to the Executive and/or the Executive's family any
other amounts or benefits required to 


                                     -8-
<PAGE>

be paid or provided or which the Executive and/or the Executive's family is 
eligible to receive pursuant to this Agreement and under any plan, program, 
policy or practice or contract or agreement of the Company and its affiliated 
companies as in effect and applicable generally to other executives and their 
families during the 90-day period immediately preceding the Applicable Date 
(such other amounts and benefits shall be hereinafter referred to as the 
"Other Benefits").  

          (b)    DEATH.  If the Executive's employment is terminated by
reason of the Executive's death during the Employment Period, this Agreement
shall terminate without further obligations to the Executive's legal
representatives under this Agreement, other than for (i) payment of Accrued
Obligations (which shall be paid to the Executive's estate or beneficiary, as
applicable, in a lump sum in cash within 30 days of the Date of Termination) and
the timely payment or provision of the Welfare Benefit Continuation and Other
Benefits and (ii) payment to the Executive's estate or beneficiary, as
applicable, in a lump sum in cash within 30 days of the Date of Termination of
an amount equal to the sum of the Severance Amount and the Supplemental
Retirement Amount.

          (c)    DISABILITY.  If the Executive's employment is terminated by
reason of the Executive's Disability during the Employment Period, this
Agreement shall terminate without further obligations to the Executive, other
than for (i) payment of Accrued Obligations (which shall be paid to the
Executive in a lump sum in cash within 30 days of the Date of Termination) and
the timely payment or provision of the Welfare Benefit Continuation and Other
Benefits (excluding, in each case, Disability Benefits (as defined below)) and
(ii) payment to the Executive in a lump sum in cash within 30 days of the Date
of Termination of an amount equal to the greater of (A) the sum of the Severance
Amount and the Supplemental Retirement Amount and (B) the present value
(determined as provided in Section 280G(d)(4) of the Code) of any cash amount to
be received by the Executive as a disability benefit pursuant to the terms of
any long term disability plan, policy or arrangement of the Company and its
affiliated companies, but not including any proceeds of disability insurance
covering the Executive to the extent paid for on a contributory basis by the
Executive (which shall be paid in any event as an Other Benefit) (the benefits
included in this clause (B) shall be hereinafter referred to as the "Disability
Benefits").

          (d)    CAUSE; BY EXECUTIVE OTHER THAN FOR GOOD REASON AND OTHER
THAN DURING A WINDOW PERIOD.  If the Executive's employment shall be terminated
for Cause during the Employment Period, this Agreement shall terminate without
further obligations to the Executive other than the obligation to pay to the
Executive Annual Base Salary through the Date of Termination plus the amount of
any compensation previously deferred by the Executive, in each case to the
extent theretofore unpaid.  If the Executive terminates employment during the
Employment Period, excluding a termination either for Good Reason or without any
reason during the Window Period, this Agreement shall terminate without further
obligations to the Executive, other than for Accrued Obligations and the timely
payment or provision of Other Benefits.  In such case, all Accrued Obligations
shall be paid to the Executive in a lump sum in cash within 30 days of the Date
of Termination.


     7.   NON-EXCLUSIVITY OF RIGHTS.  Except as provided in Section 6(a)(ii), 
6(b) and 6(c) of this Agreement, nothing in this Agreement shall prevent or 
limit the Executive's continuing or future participation in any plan, 
program, policy or practice provided by the Company or any of its 


                                     -9-
<PAGE>

affiliated companies and for which the Executive may qualify, nor shall 
anything herein limit or otherwise affect such rights as the Executive may 
have under any contract or agreement with the Company or any of its 
affiliated companies. Amounts which are vested benefits or which the 
Executive is otherwise entitled to receive under any plan, policy, practice 
or program of or any contract or agreement with the Company or any of its 
affiliated companies at or subsequent to the Date of Termination shall be 
payable in accordance with such plan, policy, practice or program or contract 
or agreement except as explicitly modified by this Agreement.

     8.   FULL SETTLEMENT; RESOLUTION OF DISPUTES.  (a) The Company's
obligation to make payments provided for in this Agreement and otherwise to
perform its obligations hereunder shall not be affected by any set-off,
counterclaim, recoupment, defense or other claim, right or action which the
Company may have against the Executive or others.  In no event shall the
Executive be obligated to seek other employment or take any other action by way
of mitigation of the amounts payable to the Executive under any of the
provisions of this Agreement and, except as provided in Section 6(a)(ii) of this
Agreement, such amounts shall not be reduced whether or not the Executive
obtains other employment.  If there is any contest by the Company concerning the
Payments or benefits to be provided to the Executive hereunder whether through
litigation, arbitration or mediation, or with respect to the validity or
enforceability of, or liability under, any provision of this Agreement or any
guarantee of performance thereof, and the Executive is the prevailing party, the
Company agrees to pay promptly upon conclusion of the contest all legal fees and
expenses which the Executive may reasonably have incurred.


          (b)    If there shall be any dispute between the Company and the
Executive (i) in the event of any termination of the Executive's employment by
the Company, whether such termination was for Cause, or (ii) in the event of any
termination of employment by the Executive, whether Good Reason existed, then,
unless and until there is a final, nonappealable judgment by a court of
competent jurisdiction declaring that such termination was for Cause or that
Good Reason did not exist, the Company shall pay all amounts, and provide all
benefits, to the Executive and/or the Executive's family or other beneficiaries,
as the case may be, that the Company would be required to pay or provide
pursuant to Section 6(a) hereof as though such termination were by the Company
without Cause or by the Executive with Good Reason; provided, however, that the
Company shall not be required to pay any disputed amounts pursuant to this
paragraph except upon receipt of an undertaking (which need not be secured) by
or on behalf of the Executive to repay all such amounts to which the Executive
is ultimately adjudged by such court not to be entitled.


     9.   CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.  (a) Anything in this
Agreement to the contrary notwithstanding, in the event it shall be determined
that any payment or distribution by the Company to or for the benefit of the
Executive (whether paid or payable or distributed or distributable pursuant to
the terms of this Agreement or otherwise, but determined without regard to any
additional payments required under this Section 9) (a "Payment") would be
subject to the excise tax imposed by Section 4999 of the Code or any interest or
penalties are incurred by the Executive with respect to such excise tax (such
excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then the Executive shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including, without limitation,
any income taxes (and any interest and penalties imposed 


                                    -10-
<PAGE>

with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the 
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax 
imposed upon the Payments.

          (b)    Subject to the provisions of Section 9(c), all 
determinations required to be made under this Section 9, including whether 
and when Gross-Up Payment is required and the amount of such Gross-Up Payment 
and the assumptions to be utilized in arriving at such determination, shall 
be made by Arthur Andersen LLP (the "Accounting Firm") which shall provide 
detailed supporting calculations both to the Company and the Executive within 
15 business days of the receipt of notice from the Executive that there has 
been a Payment, or such earlier time as is requested by the Company.  In the 
event that the Accounting Firm is serving as accountant or auditor for the 
individual, entity or group effecting the Change of Control, the Executive 
shall appoint another nationally recognized accounting firm to make the 
determinations required hereunder (which accounting firm shall then be 
referred to as the Accounting Firm hereunder).  All fees and expenses of the 
Accounting Firm shall be borne solely by the Company.  Any Gross-Up Payment, 
as determined pursuant to this Section 9, shall be paid by the Company to the 
Executive within five days of the receipt of the Accounting Firm's 
determination.  If the Accounting Firm determines that no Excise Tax is 
payable by the Executive, it shall furnish the Executive with a written 
opinion that failure to report the Excise Tax on the Executive's applicable 
federal income tax return would not result in the imposition of a negligence 
or similar penalty.  Any determination by the Accounting Firm shall be 
binding upon the Company and the Executive.  As a result of the uncertainty 
in the application of Section 4999 of the Code at the time of the initial 
determination by the Accounting Firm hereunder, it is possible that Gross-Up 
Payments which will not have been made by the Company should have been made 
("Underpayment"), consistent with the calculations required to be made 
hereunder.  In the event that the Company exhausts its remedies pursuant to 
Section 9(c) and the Executive thereafter is required to make a payment of 
any Excise Tax, the Accounting Firm shall determine the amount of the 
Underpayment that has occurred and any such Underpayment shall be promptly 
paid by the Company to or for the benefit of the Executive.

          (c)    The Executive shall notify the Company in writing of any 
claims by the Internal Revenue Service that, if successful, would require the 
payment by the Company of the Gross-Up Payment.  Such notification shall be 
given as soon as practicable but no later than ten business days after the 
Executive is informed in writing of such claim and shall apprise the Company 
of the nature of such claim and the date on which such claim is requested to 
be paid.  The Executive shall not pay such claim prior to the expiration of 
the 30-day period following the date on which it gives such notice to the 
Company (or such shorter period ending on the date that any payment of taxes 
with respect to such claim is due).  If the Company notifies the Executive in 
writing prior to the expiration of such period that it desires to contest 
such claim, the Executive shall:

          (i)    give the Company any information reasonably requested by the 
Company relating to such claim,

          (ii)   take such action in connection with contesting such claim as 
the Company shall reasonably request in writing from time to time, including, 
without limitation, accepting legal representation with respect to such claim 
by an attorney reasonably selected by the Company,


                                    -11-
<PAGE>

          (iii)  cooperate with the Company in good faith in order
effectively to contest such claim, and


          (iv)   permit the Company to participate in any proceedings 
relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses.  Without limitation on the foregoing provisions
of this Section 9(c), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct the Executive to pay the tax claimed and sue for a refund or contest the
claim in any permissible manner, and the Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further provided that any extension of the statute of limitations relating
to payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount.  Furthermore, the Company's control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issue raised by the Internal Revenue Service or any other taxing
authority.

          (d)    If, after the receipt by the Executive of an amount advanced 
by the Company pursuant to Section (c), the Executive becomes entitled to 
receive any refund with respect to such claim, the Executive shall (subject 
to the Company's complying with the requirements of Section 9(c)) promptly 
pay to the Company the amount of such refund (together with any interest paid 
or credited thereon after taxes applicable thereto).  If, after the receipt 
by the Executive of an amount advanced by the Company pursuant to Section 
9(c), a determination is made that the Executive shall not be entitled to any 
refund with respect to such claim and the Company does not notify the 
Executive in writing of its intent to contest such denial of refund prior to 
the expiration of 30 days after such determination, then such advance shall 
be forgiven and shall not be required to be repaid and the amount of such 
advance shall be offset, to the extent thereof, the amount of Gross-Up 
Payment required to be paid.

     10.  CONFIDENTIAL INFORMATION.  The Executive shall hold in a fiduciary
capacity for the benefit of the Company all secret or confidential information,
knowledge or data relating to the Company or any of its affiliated companies,
and their respective businesses, which shall have been obtained by the Executive
during the Executive's employment by the Company or any of its affiliated
companies and which shall not be or become public knowledge (other than by acts
by the Executive or representatives of the Executive in violation of this
Agreement).  After termination of 


                                    -12-
<PAGE>

the Executive's employment with the Company, the Executive shall not, without 
the prior written consent of the Company or as may otherwise be required by 
law or legal process, communicate or divulge any such information, knowledge 
or data to anyone other than the Company and those designated by it.  In no 
event shall an asserted violation of the provisions of this Section 10 
constitute a basis for deferring or withholding any amounts otherwise payable 
to the Executive under this Agreement.

     11.  SUCCESSORS.  (a) This Agreement is personal to the Executive and
without the prior written consent of the Company shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution.  This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.  

          (b)    This Agreement shall inure to the benefit of and be binding
upon the Company and its successors and assigns.  

          (c)    The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.


     12.  MISCELLANEOUS.  (a) This Agreement shall be an unfunded obligation
of the Company.

          (b)    THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REFERENCE TO PRINCIPLES
OF CONFLICT OF LAWS.  The captions of this Agreement are not part of the
provisions hereof and shall have no force or effect.  This Agreement may not be
amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.


          (c)    All notices and other communications hereunder shall be in
writing and shall be given by hand delivery to the other party or by registered
or certified mail, return receipt requested, postage prepaid, addressed as
follows:


          IF TO THE EXECUTIVE:

                     Chief Administrative Officer


or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notice and communications shall be effective
when actually received by the addressee.

          (d)    The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement.

          (e)    The Company may withhold from any amounts payable under this 
Agreement such Federal, state or local taxes as shall be required to be 
withheld pursuant to any applicable law or regulation.

          (f)    The Executive's or the Company's failure to insist upon 
strict compliance with any provision hereof or any other provision of this 
Agreement or the failure to assert any right the Executive or the Company may 
have hereunder, including, without limitation, the right of the Executive to 
terminate employment for Good Reason pursuant to Section 5(c)(i)-(v) of this 
Agreement, shall not be deemed to be a waiver of such provision or right or 
any other provision or right of this Agreement.

          IN WITNESS WHEREOF, the Executive has hereunto set the Executive's
hand and, pursuant to the authorization from its Board of Directors, the Company
has caused these presents to be executed in its name on its behalf, all as of
the day and year first above written.

    This Amended and Restated Bareboat Charter (this "Agreement"), made and
entered into as of the 9th day of February 1996, by and between Tantawan
Production B.V., a Netherlands corporation ("Lessor"), and Tantawan Services, L
L C, a Delaware limited liability company ("Charterer"), acting through its Thai

                              W I T N E S S E T H
 
      WHEREAS, the Petroleum Authority of Thailand ("PTT") and Thaipo Limited,
Thai Romo Limited and The Sophonpanich Co., Ltd. have entered into that certain
Gas Sales Agreement dated November 7, 1995 (the "Gas Sales Agreement") in
connection with the Petroleum Concession Agreement No. 1/2534/36, dated August

Industry to Maersk Oil (Thailand) Ltd., Thaipo, Limited and Thai Romo, Limited,
and Supplementary Petroleum Concession No. 1 to Petroleum Concession No.
1/2534/36, dated March 6, 1992, whereby The Sophonpanich Co., Ltd., entered into
Petroleum Concession No. 1/2534/36 (collectively, the "Concession Agreement");
 
      WHEREAS Thaipo Limited, Thai Romo Limited and Palang Sophon Limited
(formerly known as Sophon Thai Gulf Limited which was successor in interest to
The Sophonpanich Co. Ltd.) are currently the Concessionaires under the
Concession Agreement (collectively "the Concessionaires");
 
      WHEREAS, Charterer desires to charter from Lessor on a bareboat basis a
Floating Production Storage and Offloading System known as the "Tantawan
Explorer" (the "FPSO"), for use in the Tantawan Field, Thailand;
 
      NOW, THEREFORE, in consideration of the mutual covenants herein contained,
Lessor and Charterer agree as follows:
 
1.    TRANSPORTATION, INSTALLATION AND COMMISSIONING OF THE FPSO
 
     Lessor shall be responsible for delivery (the "Delivery") of the FPSO to
     Charterer in international waters offshore the yard at which the FPSO is
     being converted (the "Delivery Site") as evidenced by a certificate of
     delivery issued by Lessor and countersigned by Charterer. Prior to
     Delivery, Lessor shall be fully responsible for and assume all risks with
     respect to the FPSO. Charterer has hired an operator ("Operator") pursuant
     to an Operating Agreement (the "Operating Agreement") to operate the FPSO
     commencing with Delivery. Operator shall be responsible for completing all
     work to be performed in respect of the FPSO until Field Acceptance, as
     herein defined, has occurred, including transporting the FPSO from the
     Delivery Site to the site in the Tantawan Field designated by Charterer
     (the "Offshore Site"), hooking-up the FPSO on its anchoring system and
     hydrostatic, electrical and instrumentation testing. Operator shall also be
     responsible for commissioning the FPSO.
 
2.    FPSO TO BE CHARTERED
 
     Charterer hereby agrees to bareboat charter the FPSO as described in
     APPENDIX A and its inventory from Lessor, for the period and upon the terms
     and conditions stated herein. Lessor represents, undertakes and warrants
     that at the time of Delivery the FPSO shall comply with the requirements of
     the design basis set forth in APPENDIX A hereto (the "Design Basis") and
     shall be properly documented and classed as ABS A1 Floating Production,
     Storage and Offloading System, with no recommendations and as per the
     particulars of APPENDIX A. Lessor shall before and at the time of Delivery
     make the FPSO seaworthy and in every respect ready in hull, machinery and
     equipment for service hereunder.
 
                                       1
<PAGE>
3.    SERVICE
 
     Charterer shall have the full use of the FPSO at the Offshore Site and,
     subject to Lessor's approval, at any other place in the world where its
     operation is not prohibited by applicable law and/or regulations. Charterer
     may subcontract to identified subcontractors certain of its obligations
     hereunder, including, but not limited to, those relating to the operation,
     maintenance and repair of the FPSO. However, such subcontracts shall not
     relieve Charterer of such obligations.
 
4.    DURATION OF CHARTER
 
4.1   The term (the "Initial Term") of this Agreement shall commence upon
     Delivery. The Initial Term shall end upon a date eleven (11) years and six
     (6) months after Hire Commencement Date (as defined in Article 9.1).
 
4.2   When the FPSO is hooked up at the Offshore Site and is ready to receive
     hydrocarbons, when hydrostatic tests have been satisfactorily completed
     and, to the extent possible, when electrical and instrumentation tests have
     been satisfactorily completed, Charterer or its nominee will make an
     inspection to determine whether such events have occurred. Within
     twenty-four (24) hours of the inspection, Charterer will notify Lessor in
     writing of whether or not such events have occurred. Lessor will cause
     Operator to have available at the Offshore Site appropriate and experienced
     staff to promptly correct all items found to be unacceptable. When
     Charterer is satisfied that such events have occurred ("Field Acceptance"),
     Charterer shall sign a certificate of field acceptance to this effect. (If
     Charterer's affiliate shall fail to perform or cause to be performed the
     work of installing pipeline end manifolds ("PLEMs") and the anchoring of
     the mooring system for the FPSO at the Offshore Site and such failure shall
     have directly and solely prevented the occurrence of Field Acceptance, then
     Field Acceptance shall be deemed to have occurred as of the date Field
     Acceptance would have occurred but for Charterer's actions or failure to
     perform such action.) Field Acceptance by Charterer shall not be construed
     as a waiver or discharge of any of the representations, warranties or
     undertakings of Lessor in or with respect to this Agreement or the FPSO.
 
4.3   Upon the expiration of the Initial Term, Charterer shall have the option
     to terminate this Agreement, extend this Agreement on an annual basis at
     prices to be agreed upon by Lessor and Charterer, or purchase the FPSO
     pursuant to Article 23. The election of any such option may be exercised by
     Charterer's giving Lessor notice thereof at least 360 days prior to the
     expiration of the Initial Term. If no such notice is received, Charterer
     shall be deemed to have exercised its option to terminate this Agreement as
     of the end of the Initial Term. If Charterer elects to extend this
     Agreement, then Charterer and Lessor shall negotiate in good faith in an
     effort to reach agreement prior to the end of the Initial Term on a Total
     Bareboat Rate for the subsequent annual term. If no such agreement is
     reached, Charterer shall have the additional option to purchase the FPSO as
     aforesaid by notice to Lessor at least 180 days prior to the end of the
     Initial Term. If no agreement on a Total Bareboat Rate for an extended term
     is timely reached and if no notice of an election to purchase the FPSO is
     timely given, Charterer shall be deemed to have exercised its option to
     terminate this Agreement as of the end of the Initial Term. If an agreement
     on Total Bareboat Rate for an extended term is reached, this Agreement
     shall be extended until the first anniversary date of the end of the
     Initial Term and this Article 4.3 shall apply at the end of said extended
     term MUTATIS MUTANDIS.
 
5.    GUARANTEES
 
5.1   Simultaneously with the execution of this Agreement, Charterer shall
     furnish to Lessor several guarantees limited to field percentage interest
     (the "Joint Venturer Guarantees") of Charterer's performance under this
     Agreement which shall be given by Thaipo Limited, Thai Romo Limited and
     Sophon Thai Gulf Limited (the "Joint Venturers") in the form of APPENDIX
     B-1 hereto.
 
                                       2
<PAGE>
5.2   As security for payment of Hire (as hereinafter defined) and other amounts
     due to Lessor hereunder, Charterer shall grant or cause the Concessionaires
     to grant (to the extent permitted by Thai law) a security interest to
     Lessor in all oil produced from the Tantawan Field taken on board the FPSO
     and the proceeds thereof, such security interest to be subordinate to
     royalties, taxes and field operating expenses and granted on a PARI PASSU
     basis, with all lenders financing the development of the Tantawan Field.
     Charterer shall fully assist Lessor in perfecting such a security interest,
     to the extent permitted by the laws of the United States of America and the
     laws of Thailand. Charterer shall not agree to permit such other lenders to
     perfect their security interests if Lessor is unable or elects not to
     perfect its security interest.
 
5.3   Lessor has delivered to Charterer a Guarantee and Indemnity Agreement
     ("Lessor Parent Company Guarantee") in the form of APPENDIX B-2 hereto,
     executed by its ultimate corporate parent, IHC Caland N.V., guaranteeing
     the performance by Lessor of its obligations hereunder.

     MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE OR USE OF THE FPSO OR
     ANY PART THEREOF.
 
7.    MAINTENANCE AND OPERATION
 
7.1   Lessor agrees that the FPSO shall, for the duration of the charter term,
     be in the full possession and at the absolute disposal for all purposes of
     Charterer and under its complete control in every respect. Subject to
     Article 7.3, as necessary to meet and maintain requirements of the American
     Bureau of Shipping ("ABS"), Charterer shall maintain the FPSO in a good
     state of repair. In addition, Charterer shall maintain the FPSO in
     efficient operating condition and in accordance with good commercial
     maintenance practice, and shall keep the FPSO with valid, unexpired
     classification of the class as indicated in Article 2, free of
     recommendations and notations affecting class. Charterer shall furnish
     Lessor with one duplicate original or certified true copy of all class and
     flag certificates issued or notated during the duration of the charter upon
     their issuance or notation. Lessor shall keep all Thai, Bahamian (the
     "Country of Registry") and other required certificates valid, up-to-date
     and in full force at all times. Charterer shall maintain the following
     maintenance reports, records, surveys and documents: Planned Maintenance
     System, Continuous Survey of Machinery and such other reports, records,
     surveys and documents as Lessor shall reasonably specify in writing.
     Charterer shall provide copies of such documents to Lessor upon Lessor's

     authorizations which Charterer may reasonably require in order to
     accomplish the actions required or permitted to Charterer under this
     Article 7.
 
                                       4
<PAGE>
7.2   Subject to Article 7.3, Charterer shall take immediate steps to have all
     necessary repairs done within a reasonable time.
 
7.3   Notwithstanding the terms of Articles 7.1 and 7.2, Major Repairs necessary
     to meet and maintain ABS requirements and the Design Basis shall be the
     responsibility of Lessor provided always that Charterer has not caused the
     need for such repairs as a result of Charterer's gross negligence or
     willful misconduct. "Major Repairs" shall mean all repairs to the FPSO
     other than: (a) repairs resulting from corrosion caused by a combination of
     carbon dioxide and water in the gas stream, and (b) repairs costing less
     than U.S. $100,000 per incident. Such Major Repairs shall be carried out by
     Lessor and Charterer shall provide all necessary assistance.
 
7.4   In the event of any improvement, structural changes or new equipment
     becoming necessary for the continued operation of the FPSO by reason of new
     class requirements or compulsory legislation or in order to maintain the
     FPSO in compliance with the Design Basis, then Lessor shall carry out such
     work at its expense.
 
7.5   Charterer shall establish and maintain financial security of
     responsibility in respect of oil or other pollution damage as required by
     any government or other division or authority thereof, to enable the FPSO,
     without penalty or charge, lawfully to enter and remain at the Offshore
     Site in performance of this Agreement or in the case of removal of the FPSO
     to another site as may be permitted by the terms hereof, at such other
     site. Charterer shall make and maintain all arrangements by bond or
     otherwise as may be necessary to satisfy such requirements at Charterer's
     sole expense.
 
7.6   Charterer shall at its own expense and by its own procurement, except as
     stated to the contrary elsewhere, man, victual, operate, supply, fuel and
     repair the FPSO whenever required during the duration of this Agreement and
     shall pay all charges and expenses of every kind and nature whatsoever
     incidental to its use and operation of the FPSO under this Agreement. The
     Master, officers, crew and production personnel of the FPSO shall be the
     servants of Charterer for all purposes whatsoever.
 
7.7   Charterer shall comply with the regulations of the Country of Registry
     and, to the extent applicable, the Kingdom of Thailand. Charterer will
     cause the FPSO to comply at all times with all applicable laws, treaties
     and conventions and with all rules and regulations issued thereunder and to
     have on board, when required thereby, valid certificates showing compliance
     therewith.
 
7.8   During the duration of this Agreement the FPSO shall retain her present
     name and shall remain under and fly the Bahamian flag, provided, however,
     that Charterer shall have the liberty to paint the FPSO in its own colors,
     install and display its funnel insignia and fly its own house flag.
     Painting and repainting, installment and re-instalment shall be for
     Charterer's account.
 
7.9   (a)  Subject to Article 7.4 and Lessor's approval, which shall not be
     unreasonably withheld, Charterer shall have the right to add additional
     equipment, modify existing equipment or connect additional production
     facilities. Any such additions or modifications, including the installation
     thereof, shall be at the sole cost, risk and expense of Charterer. Such
     additions, modifications and connections so installed shall, without
     necessity of further act, become part of the FPSO and the property of
     Lessor; PROVIDED, HOWEVER, that so long as no Event of Default shall have
     occurred and be continuing, any such additions, modifications and
     connections not required to be installed in order to meet the requirements
     of Article 7.4 hereof and not installed as replacements for property
     included on board the FPSO on the date of Field Acceptance may be removed
     (so long as such removal can be accomplished without damage to the FPSO) by
     Charterer, at its own expense and risk, at any time during, or at the
     expiration of, the Initial Term upon reasonable prior notice, whereupon
     such equipment shall, without necessity of further act, become the property
     of Charterer.
 
                                       5
<PAGE>
     (b)  Charterer may, in the ordinary course of maintenance, repair or
     overhaul of the FPSO, remove any item of property constituting a part of
     the FPSO; PROVIDED, HOWEVER, that such item is replaced as promptly as
     possible by an item of property which is free and clear of all liens,
     encumbrances and rights of others and is in as good operating condition, is
     as seaworthy and has a value and utility at least equal to the item of
     property being replaced. Any item of property removed from the FPSO as
     provided in the preceding sentence shall remain the property of Lessor
     until replaced in accordance with the terms of such sentence, but shall
     then, without further act, become the property of Charterer. Any such
     replacement item of property shall, without further act, become the
     property of Lessor and be deemed part of the FPSO as defined herein for all
     purposes hereof.
 
7.10  Charterer shall have the use of all items of inventory, equipment and
     spares being part of or on board the FPSO on the date of Delivery, which
     Lessor undertakes to provide. Such inventory will be specified pursuant to
     Article 14.
 
8.    INSPECTION
 
8.1   Lessor shall have the right at any reasonable time to inspect or survey
     the FPSO itself or to instruct a duly authorized third-party surveyor to
     carry out such survey on its behalf to ascertain the condition of the FPSO,
     and to satisfy itself that the FPSO is being properly repaired, maintained
     and operated. Such inspections and surveys shall be for Lessor's account.
     Charterer shall provide, free of charge to Lessor, upon reasonable request
     by Lessor, transportation from the shore base to the FPSO and vice versa on
     its regular flights and, to the extent available, accommodations, catering
     and communication on board for such inspectors or surveyors.
 
8.2   Charterer shall also permit Lessor to inspect the FPSO's log books
     whenever requested and shall immediately furnish Lessor with full
     information regarding any casualties or other accidents or damage to or
     caused by the FPSO.
 
9.    COMPENSATION
 
9.1   As full compensation for the performance by Lessor of its obligations
     under this Agreement, Charterer shall pay Lessor a hire ("Hire"). Hire
     shall accrue in accordance with this Article 9 commencing at 0001 hours
     local time at the Offshore Site on the date ("Hire Commencement Date") on
     which both (a) Field Acceptance, and (b) the earlier of (i) December 20,
     1996 or (ii) the date on which hydrocarbons begin flowing through the FPSO,
     shall have occurred.
 
     Except as otherwise provided herein, Hire shall continue to accrue until
     the date when the FPSO is redelivered to Lessor under the terms of this
     Agreement. Hire for the first ten (10) years after the Hire Commencement
     Date shall be paid at the rate of $65,752 per day, and Hire for the final
     eighteen (18) months of the Initial Term shall be paid at the rate of
     $43,227 per day (as applicable, the "Total Bareboat Rate") in the manner
     provided for in Article 24, subject to adjustment by mutual agreement of
     the parties, and, except as otherwise specifically provided herein, no
     other compensation or reimbursement shall be due to Lessor for the
     performance of its obligations hereunder.
 
9.2   Payment of Hire shall be made monthly in arrears, without any discount,
     adjustment, set off or deduction, except as specifically set forth in this
     Article 9 or otherwise in this Agreement. Lessor shall provide invoices to
     Charterer covering each payment of Hire at least ten (10) days before due.
     Payment of Hire shall be made to such U.S. Dollar account or accounts with
     such European office of a first class bank as Lessor shall designate in
     writing. Lessor shall not change such designations without Charterer's
     consent, which consent shall not be withheld unless Charterer determines
     that:
 
      (i) such change would increase Charterer's costs; or
 
      (ii) such change would expose Charterer to the risk of double payment.
 
                                       6
<PAGE>
     The first payment of Hire shall be paid in same day funds before the close
     of business at the place of payment on the first business day of the
     calendar month beginning after the Hire Commencement Date. Except as
     otherwise provided in this Agreement, subsequent payments of Hire shall be
     paid in same day funds at the place of payment on the first business day of
     each applicable calendar month during the Initial Term or an extended term
     ("Hire Payment Date"). Hire shall accrue on a daily basis; provided that
     Hire for any periods that constitute less than a calendar day shall be a
     pro rata portion of Hire for such calendar day. If a Hire Payment Date
     falls on a day which is not a banking day at the place of payment, payment
     shall instead be made on the next succeeding day that is a banking day at
     such place. Any Hire paid but not earned shall be refunded on the next Hire
     Payment Date (or as otherwise provided under this Agreement) to Charterer
     by Lessor.
 
9.3   Upon request by Charterer, Lessor shall promptly pay to Charterer, or at
     the option of Charterer, at any time following an Event of Default by
     Lessor hereunder or a default under the Lessor Parent Company Guarantee,
     Charterer shall be entitled to deduct from the payments of Hire:
 
      (i) actual or reasonably estimated disbursements, if any, for Lessor's
          account;
 
      (ii) any advances to the master of the FPSO (the "Master") or to Lessor's
           affiliates, contractors, subcontractors, or agents for expenses or
           disbursements for Lessor's account;
 
     (iii) any previous overpayment of Hire, including payments made with
           respect to periods of Downtime;
 
      (iv) any sums due in respect of Lessor's failure to meet Lessor's
           performance undertakings under this Agreement; and
 
      (v) any other sums or credits to which Charterer is entitled under this
          Agreement.
 
     If a deduction is made based on an estimate, the next Hire payment shall be
     adjusted, if necessary, to reflect any difference between such estimate and
     the actual amount of deduction that Charterer is able to verify. All
     deductions from Hire shall be verified by Charterer by production of
     vouchers or supporting documentation corresponding to the deductions within
     thirty (30) days after the applicable Hire Payment Date.
 
9.4   Notwithstanding anything contained in this Article 9 to the contrary, the
     final payment of Hire hereunder shall be made on the date of redelivery of
     the FPSO to Lessor. Deductions, to the extent permitted by Article 9.3,
     from said final payment shall be those reasonably estimated by Charterer if
     the actual amounts have not been determined and also less the amount
     estimated by Charterer to become payable by Lessor for fuel and supplies on
     redelivery of the FPSO to Lessor as provided in Article 25.
 
9.5   (a)  Should the FPSO become an actual total loss, Hire shall cease at the
     time of its loss or, if such time is unknown, at the time when the FPSO was
     last heard of. Should the FPSO become a total loss of any other kind, if
     approved in writing by Charterer in accordance with sub-clause (d) below,
     including, without limitation, a constructive, compromised, agreed or
     arranged total loss (a "constructive total loss"), Hire shall cease at the
     time of the casualty resulting in such loss. Within ninety (90) days after
     Hire has ceased under this Article 9.5, all monies owing to Charterer under
     the provisions of this Agreement at the time Hire ceases under this Article
     9.5 shall be paid to Charterer, and likewise Lessor shall be paid the net
     amount of all sums due from Charterer. If the FPSO shall have been missing
     for at least forty-eight (48) hours when a payment of Hire would otherwise
     be due, such payment shall be postponed until the safety of the FPSO is
     ascertained.
 
     (b)  Should the FPSO become an actual total loss or a constructive total
     loss (i) for reasons other than negligence or willful misconduct of Lessor
     Group and (ii) in circumstances where no Event of Default by Lessor or its
     affiliates, its Guarantor or the Operator (a "Lessor Party") has occurred
     and is continuing, this Agreement shall be deemed to be terminated as of
     the date on which the
 
                                       7
<PAGE>
     obligation to pay Hire ceases in accordance with Article 9.5(a) without
     prejudice to (A) the payment obligations of Lessor and Charterer as
     described in Article 9.5(a) and (B) any other provisions which would
     otherwise survive termination of this Agreement which, for the avoidance of
     doubt, does not include any obligation to rebuild the FPSO or procure a new
     FPSO.
 
     (c)  Should the FPSO become an actual total loss or a constructive total
     loss either (i) for reasons where the negligence or willful misconduct of a
     member of Lessor Group is a contributing factor or (ii) in circumstances
     where an Event of Default by a Lessor Party has occurred and is continuing,
     then, irrespective of such total loss, Charterer shall have the remedies
     set out in Article 31 hereof.
 
     (d)  Lessor and its affiliates shall not be entitled to (i) claim under
     this Agreement or (ii) reach agreement with the insurers on the hull
     policies taken out by Lessor and its affilates that, in either case, the
     FPSO constitutes a total loss of any kind other than an actual total loss
     without the prior written approval of Charterer.
 
     (e)  An actual total loss or a constructive total loss will not constitute
     in and of itself an Event of Default.
 
9.6   In the event Charterer fails to make any payment (including without
     limitation any payment of Hire) due and owing to Lessor under this
     Agreement, Lessor shall so notify Charterer. If Charterer fails to pay
     amounts due and owing within five (5) business days after receipt of such
     notice, Charterer shall pay to Lessor, in addition to all other amounts
     then due and owing, a late fee at a rate equal to one-month LIBOR plus two
     percent (2%) on the amounts then due and owing for the period of said fifth
     (5th) day until paid without prejudice to any other remedies under this
     Agreement.
 
9.7   All payments of Hire and other amounts due hereunder from one party to the
     other shall be made in U.S. Dollars by interbank transfer. Except as
     otherwise provided herein, all sums due by one party to the other shall be
     paid within 30 days of receipt of invoice.
 
9.8   Charterer shall be responsible for obtaining and shall use all reasonable
     efforts to obtain exchange control approval for payments under this
     Agreement.
 
10.   CHANGE IN LAW
 
10.1  The Total Bareboat Rate is based on the tax laws of Thailand and Holland
     as of the date of this Agreement and assumes a tax burden of 1.1% of the
     Total Bareboat Rate. In the event there are any changes in Thailand tax
     laws or their interpretation which affect the cost to the Lessor of
     chartering the FPSO, the Total Bareboat Rate shall be revised upwards or
     downwards to take into account such change in costs; provided, however,
     Charterer shall not be obligated to pay any Thai, Dutch or U.S. tax burden
     up to a total amount equal to 2.2% of the Total Bareboat Rate and further
     provided Lessor shall use all reasonable efforts to maintain its present
     status under the tax treaty between Thailand and the Netherlands and shall
     take all reasonable actions to prevent or minimize any such increased
     expenses. Any increase in the total tax burden on the Total Bareboat Rate
     in excess of 2.2% of the Total Bareboat Rate attributable to any changes in
     Dutch tax laws shall be for Lessor's account. Any adjustment of said
     compensation shall be effective as of the effective date of the change in
     such tax burden; provided, Lessor shall furnish to Charterer the necessary
     supporting documentation evidencing such changes within a reasonable time.
 
10.2  The parties hereto do not believe that any U.S. taxes are applicable to
     payments made under this Agreement. To the extent that U.S. withholding
     taxes are assessed on Hire payable hereunder, Hire shall be increased such
     that the net Hire received by Lessor hereunder shall not be affected by
     such U.S. withholding taxes. Lessor agrees to use its best efforts to
     promptly obtain a refund of any such U.S. income taxes which have been
     withheld in excess of Lessor's U.S. tax obligations and to promptly repay
     such refund to Charterer.
 
                                       8

11.   TAXES
 
     Subject to Article 10, all taxes (including income and withholding taxes)
     which are due with respect to the payment of the Total Bareboat Rate
     pursuant to this Agreement shall be paid by Lessor or reimbursed to
     Charterer by Lessor, except that Thailand value added taxes ("VAT"), other
     Thailand sales/use taxes and Thailand customs and import duties applicable
     to the FPSO, shall be paid by Charterer or reimbursed to Lessor by
     Charterer. Charterer or its designee on the behalf of the Concessionaires
     shall be designated as the importer of the FPSO and be responsible for
     customs clearance and obtaining import licenses on the FPSO.
 
12.   CONFLICTS OF INTEREST
 
     Neither Lessor nor any of its subcontractors shall pay any fee, commission,
     rebate or other thing of value to, or for the benefit of, any employee of
     Charterer, its principals or any of its or their affiliates, nor shall
     Lessor do business with any company knowing that the results thereof might
     benefit an employee of the Charterer, its principals or any of its or their
     affiliates.
 
13.   LIENS AGAINST THE FPSO
 
13.1  a)  Neither Charterer nor the master of the FPSO nor any other person
          shall have any right, power or authority to create, incur or permit to
          exist upon the FPSO any lien, charge or encumbrance other than
          Permitted Encumbrances. Lessor may fasten to the FPSO in a conspicuous
          place and maintain during the term of this Agreement a notice reading
          as follows:
 
                               NOTICE OF CHARTER
 
           This Vessel is mortgaged to               , and is under
           charter to Tantawan Services, L L C With the exception of
           such mortgage, under the terms of said charter, neither
           the charterer, any subcharterer, the master of this
           Vessel, nor any other person has the right, power or
           authority to create, incur or permit to be placed or
           imposed upon this Vessel, or its profits, any lien
           whatsoever, other than liens for master's and crew's wages
           or salvage or as otherwise provided under said charter.
 
     b)  Lessor warrants that it has not created and covenants that it will not
        create or permit to exist, and shall indemnify, hold harmless and defend
        Charterer against any loss which Charterer may sustain by reason of, any
        Owner Encumbrances.
 
     c)  "Permitted Encumbrances" shall mean (i) the rights of Charterer under
        this Agreement, (ii) the rights of Lessor under this Agreement, (iii)
        during the Initial Term or any extended term, liens for current master's
        and crew's wages and salvage, (iv) Lessor Group's mortgage of the FPSO
        in favor of certain lending institutions ("Lenders") provided Charterer
        shall have received satisfactory assurances from the Lenders as to the
        exercise of Charterer's rights under this Agreement in the absence of an
        Event of Default by Charterer and the expiration of all cure periods
        relevant thereto, and (v) liens arising in tort which are covered by
        insurance; and "Permitted Encumbrance" shall mean any of the foregoing.
 
     d)  "Owner Encumbrances" shall mean any liens, security interests or
        encumbrances resulting from voluntary action by Lessor Group, as
        hereinafter defined, taken without the prior written approval of
        Charterer and not taken as the result of an Event of Default by
        Charterer.
 
13.2  Charterer agrees that if a libel or a complaint in admiralty (for purposes
     of this Article 13.2 called a "claim") shall be filed against the FPSO, or
     if the FPSO shall be otherwise levied upon or taken into custody or
     detained or sequestered by virtue of proceedings in any court or tribunal
     or by any government or other authority because of any claim (excluding a
     claim against Lessor), Charterer shall at its own expense within 15 days
     thereafter cause the FPSO to be released and each such
 
                                       9
<PAGE>
     claim to be discharged (except to the extent that the same shall be
     contested by Charterer in good faith by appropriate proceedings and shall
     not affect the continued use of the FPSO). Charterer agrees forthwith to
     notify Lessor by telegram or telex, confirmed by letter, of each such claim
     involving amounts in excess of $500,000 and of the release and discharge of
     each such claim. Charterer agrees to advise in writing at least once in
     each three-month period as to the status and merits of all such claims not
     released and discharged within 15 days as provided above, which either are
     not bonded or affect the ability of Charterer to use the FPSO in the
     ordinary course of its business. Charterer agrees to indemnify, hold
     harmless and defend Lessor against any loss which Lessor may sustain by
     reason of any liens, security interests or encumbrances resulting from
     voluntary action by Charterer Group taken without the prior written
     approval of Lessor and not taken as the result of an Event of Default by
     Lessor.
 
14.   INVENTORY
 
     A complete inventory of the FPSO's entire outfit, equipment (including
     vessel equipment and supplies, cabin, crew and galley equipment),
     furniture, furnishings, appliances, spare and replacement parts and all
     unbroached consumable stores, fuel and lubricants onboard shall be jointly
     taken within thirty (30) days following Field Acceptance by representatives
     of Lessor and Charterer or by an independent outside firm as may be
     mutually agreed upon. A similar inventory shall be taken and mutually
     agreed upon at the time of Redelivery.
 
15.   GAS SALES AGREEMENT
 
     Charterer and Lessor recognize that compliance with the terms of the Gas
     Sales Agreement will be required by the parties thereto, and Lessor and
     Charterer will generally cooperate in facilitating such compliance by the
     parties thereto.
 
16.   DOWNTIME
 
16.1  Downtime shall mean any calendar day on which the FPSO is unable to
     process sufficient gas so as to deliver (and actually deliver) into the
     export pipeline the lesser of (i) 150 million cubic feet ("Mmcf") of gas or
     (ii) the amount of gas that Charterer, its affiliates and designees are
     capable of delivering to the FPSO, as determined in good faith by Charterer
     on the basis of demonstrated measured data; provided that any shortfall in
     gas delivery on a given calendar day may be made up so as to avoid Downtime
     hereunder over the three succeeding calendar days. Downtime shall also mean
     any calendar day on which the FPSO is unable to process and deliver into
     the FPSO storage tanks the lesser of (i) 40,000 barrels of liquids or (ii)
     the amount of liquids that Charterer, its affiliates and designees are
     capable of delivering to the FPSO, as determined in good faith by Charterer
     on the basis of demonstrated measured data; provided, however, that no
     Downtime shall be deemed to have occurred pursuant to this sentence if the
     FPSO's inability to process the liquids so required results solely from the
     FPSO's inability to process the quantity of gas required by the immediately
     preceding sentence. Downtime shall also mean any calendar day on which the
     FPSO is unable to offload into shuttle tankers the oil stored on the FPSO,
     other than for adverse weather conditions as specified in the Terminal
     Regulations Manual, as defined in the Operating Agreement and in
     Charterer's reasonable opinion this adversely affects the normal operation
     of the fields served by the FPSO. For purposes of this Article 16.1,
     "process" shall be interpreted to mean the processing on board the FPSO of
     gas and liquids having the properties given in the Design Basis in
     circumstances which conform to the design criteria given in the Design
     Basis.
 
16.2  Downtime shall occur notwithstanding the fact that maintenance or repairs
     (including Major Repairs but excluding those resulting from Charterer's
     gross negligence or willful misconduct) are occurring. Downtime shall not
     occur during the period that Charterer is adding or modifying equipment or
     connecting additional facilities pursuant to Article 7.9 hereof.
 
16.3  Lessor shall give Charterer sixty (60) days' prior notice of any Major
     Repairs to the FPSO.
 
                                       10
<PAGE>
16.4  Downtime shall be deemed not to occur during an event which is a Force
     Majeure event hereunder.
 
16.5  A Downtime Penalty Period shall mean any year based upon a historical
     rolling year beginning after the earlier of (i) February 28, 1997 or (ii)
     the Contractual Delivery Date, as defined in the Gas Sales Agreement. If
     Charterer desires to fix the commencement of the Downtime Penalty Period by
     reference to a Contractual Delivery Date based on completion of the seventy
     two (72) hour test ("Test") referred to in clause 6.3 of the Gas Sales
     Agreement, Charterer shall be required to obtain confirmation from Lessor
     prior to commencement of the Test that the FPSO is able to process and
     deliver Sales Gas, as defined in the Gas Sales Agreement, consistent with
     the PTT nomination made pursuant to said clause 6.3. During any Downtime
     Penalty Period (i) Charterer shall not be obligated to pay Lessor the Total
     Bareboat Rate in respect of any Downtime occurring after the first thirty
     (30) days of Downtime and (ii) if the first thirty (30) days of Downtime
     are consecutive, in addition to the foregoing, Charterer shall not be
     obligated to pay Lessor the Total Bareboat Rate for said first thirty
     (30)-day period (and if Charterer has previously paid any or all of the
     Total Bareboat Rate in respect of said first thirty (30) day period, Lessor
     shall promptly refund such amount to Charterer).

      set forth in this Agreement.
 
19.   NON-WAIVER OF DEFAULTS; NON-RECOURSE
 
19.1  Any failure by either party at any time, or from time to time, to enforce

     respect to the guarantees and collateral referred to in Article 5.
 
20.   FORCE MAJEURE
 
20.1  Any loss or damage or delay in, or failure of performance of either party
     shall not constitute default hereunder or give rise to any claims for
     damages if and to the extent that such loss, damage, delay or failure is
     caused by "Force Majeure."
 
                                       14
<PAGE>
20.2  In this Agreement "Force Majeure" shall denote any event the happening of
     which could not be prevented even though a person against whom it happened
     or threatened to happen were to take such appropriate care as might be
     expected of a Reasonable and Prudent Operator, as hereinafter defined.
     "Reasonable and Prudent Operator" when used to describe the standard of
     care to be exercised by a party in performing its obligations means the
     degree of diligence and prudence and foresight reasonably and ordinarily
     exercised by experienced operators engaged in the same line of business
     under the same or similar circumstances and conditions and when used to
     determine the action that would be required of a party means the action an
     experienced commercial operator engaged in the same line of business under
     the same or similar circumstances and conditions would take in the exercise
     of such due diligence, prudence and foresight. Notwithstanding Article
     20.1, Force Majeure shall not release either party from any obligation to
     give a notice or make any payment (including, in particular, any payment of
     Hire) under this Agreement except where the making of a payment is
     prevented by a Force Majeure event affecting the transfer of monies by the
     payor. Any payments which are so prevented from being made by reason of
     Force Majeure shall, upon the cessation of the Force Majeure event, be made
     as soon as practicable thereafter in addition to any other amounts which
     may then be payable by such party under this Agreement.
 
20.3  Events which may, subject to Article 20.2, be considered Force Majeure
     events shall include but not be limited to acts of government, strikes,
     lock-outs, acts of public enemy, wars whether declared or undeclared,
     blockades, insurrection, riots, epidemics, landslides, lightning,
     earthquakes, fires, storms, floods, washouts, civil disturbances,
     explosions, breakage or accident to machinery or lines of pipe, freezing of
     wells or lines of pipe, partial or entire failure of wells, inability to
     obtain necessary materials or supplies due to changes in laws and
     regulations, material changes in the obligations of the concessionaire
     under the Concession Agreement, as herein defined, imposed unilaterally by
     the Government of Thailand, and inability of PTT to accept delivery of
     natural gas delivered to PTT under the Gas Sales Agreement where such
     inability constitutes an event of Force Majeure under the Gas Sales
     Agreement which has been declared.
 
20.4  A party claiming relief on account of Force Majeure shall:
 
      (i) as soon as practicable give notice to the other party of the happening
          said to constitute Force Majeure, such notice to include full
          information about the circumstances and a statement of the steps and
          time believed necessary to remedy the failure but neither party shall
          be obligated to settle or prevent any strike or other industrial
          action except on terms which, in its sole judgment, are acceptable to
          it; and
 
      (ii) proceed as a Reasonable and Prudent Operator at its own expense to
           remedy the failure as rapidly as possible.
 
21.   LAW AND ARBITRATION
 
21.1  This Agreement shall be construed and governed in accordance with the
     maritime law of the United States of America and, to the extent such law is
     inapplicable, with the laws of the State of New York excluding any conflict
     of law rules. In connection with the interpretation of any exhibit hereto,
     the choice of law of this Agreement shall prevail.
 
21.2  Any dispute arising under or in connection with this Agreement shall be
     settled by arbitration in New York City under the rules of the American
     Arbitration Association, except as provided herein. The party requesting
     arbitration shall be entitled to have arbitration of the dispute
     consolidated with any other pending dispute under this Agreement or with
     any dispute arising under the Operating Agreement. The party requesting
     arbitration shall serve upon the other party a written demand for
     arbitration with the name and address of the arbitrator appointed by it,
     and such other party shall, within ten (10) days thereafter, appoint an
     arbitrator, and the two arbitrators so named, if they can agree, shall
     appoint a third, and the decision or award of any two shall be final and
 
                                       15
<PAGE>
     binding upon the parties. In no event shall any dispute or consolidated
     group of disputes be determined by more than three arbitrators. Should the
     party upon whom the demand for arbitration is served fail or refuse to
     appoint an arbitrator within ten (10) days, the single arbitrator shall
     have the right to decide alone, and his decision or award shall be final
     and binding upon the parties. The arbitrator(s) shall have the discretion
     to impose the cost of the arbitration proceedings, including reasonable
     attorney's fees upon the losing party, or divide it between the parties on
     any terms which may appear just. Any decision or award rendered hereunder
     may be made and entered as a rule or judgment of any Court, in any country
     having jurisdiction.
 
21.3  Judgment upon the arbitration award rendered may be entered in any Court
     having either personal or in rem jurisdiction, or application may be made
     to such Court for a judicial acceptance of the award and an Order of
     Enforcement, as the case may be.

23.   PURCHASE OPTION
 
     Provided that an Event of Default by Charterer under Article 30 of this
     Agreement is not existing, Charterer shall have the right to exercise an
     option (the "Purchase Option") to purchase the FPSO (including its on-board
     spare parts) from the Lessor free from all encumbrances (except
     encumbrances created by Charterer), (i) at the expiration of the Initial
     Term for a price of five million dollars ($5,000,000), or (ii) at any time
     during the Initial Term or during any extended term at a price to be
     determined by reference to Appendix C-1, or (iii) at any time during the
     Initial Term or at any time during an extended term, (A) if an Event of
     Default by Lessor has occurred under Article 30 of this Agreement and
     Charterer has elected, pursuant to Article 31.1(b) hereof to exercise this
     Purchase Option, or (B) if, in the opinion of Charterer (and, if requested
     by Lessor, in the opinion of Charterer's outside counsel), such purchase is
     required by relevant governmental authorities pursuant to applicable laws,
     rules, regulations or agreements with such governmental authorities, for a
     price determined by reference to Appendix C-2; provided that, in each of
     the forgoing cases, such purchase price shall be reduced by any amounts due
     from Lessor under this Agreement which have been established at the time of
     such purchase; provided further, in the case of a purchase pursuant to
     subsections (i) or (ii) above only, the FPSO shall not be moved to operate
     in another field outside Thailand or, if within Thailand, (i) to a field in
     which a current or future member of the Charterer Group (as defined in
     Article 18.1) does not have an interest, or (ii) unless pursuant to the
     Concession Agreement. Any Thailand sales or transfer taxes attributable to
     the sale will be paid by Charterer. If Charterer is exercising its Purchase
     Option pursuant to (i) or (iii)(A) above, Charterer shall provide notice of
     its intent to do so in accordance with the relevant provisions of this
     Agreement. If Charterer is exercising its Purchase Option pursuant to
     (iii)(B) above, Charterer shall provide notice of its intent to do so at
     the earliest reasonable practicable opportunity. If Charterer is exercising
     its Purchase Option pursuant to (ii) above, Charterer shall provide notice
     of its intent to do so at least 180 days prior to such purchase. Upon
     notification by Charterer of its intent to exercise the Purchase Option,
     Lessor shall use reasonable diligence to cause the release of all liens
     (except liens caused or created by Charterer Group) on the FPSO to be
     effective not later than closing of the sale.
 
     In the event the Purchase Option is exercised, unless agreed otherwise
     between Charterer and Lessor, Lessor shall sell the FPSO and Charterer
     shall purchase the FPSO "as is," safely afloat, at the time and place of

          (i) A certificate signed by a duly authorized executive of Lessor to
              the effect that the FPSO is free from all encumbrances (except
              encumbrances created by Charterer),
 
                                       17
<PAGE>
          (ii) A certificate signed by the appropriate government official of
               the Country of Registry showing Lessor as the sole owner of the
               FPSO and no liens of record other than encumbrances to be
               satisfied out of the FPSO's sales proceeds,
 
         (iii) One or more bills of sale executed by duly authorized officers of
               Lessor on behalf of Lessor conveying full title of the FPSO to
               Charterer in suitable form for recording or registering title,
 
          (iv) Copies of class and trading certificates (where relevant to its
               class) for the FPSO valid at the time of re-delivery,
 
          (v) All government approvals necessary to transfer the FPSO to
              Charterer and, if requested by Charterer, to delete the FPSO from
              registry in the Country of Registry and any country claiming
              jurisdiction over Lessor's power to sell the FPSO,
 
          (vi) Copies of all log books, classification certificates, manuals and
               other documents in the Lessor's or Lessor's manager's possession
               related to the FPSO's operation and maintenance, and
 
         (vii) Physical possession of the FPSO.
 
     b)  On delivery Charterer shall pay the purchase price to Lessor or its
        designee by transfer to Lessor's account then designated for receipt of
        Hire payments.
 
     c)  Each party shall deliver to the other party such additional
        documentation or take such additional action as such other party may
        reasonably request or as may be customary at the time with respect to
        the sale of vessels registered in the Country of Registry and which is
        not in conflict with the provisions of this Agreement, provided that
        Lessor shall not be required to arrange or pay for a drydocking or
        inspection of the FPSO for purposes of said sale and purchase.
 
24.   REVENUES
 
     Lessor and Charterer have entered into that certain Accounts Agreement
     dated December 19, 1996, among the Joint Venturers, Thaipo Limited as Field
     Operator, Lessor, Charterer, Operator and ABN AMRO Bank N.V., Bangkok
     Branch (the "Accounts Agreement"). If the Accounts Agreement terminates as
     the result of a Lessor Event of Default under this Agreement and,
     subsequent to such termination, such Lessor Event of Default is cured prior
     to Charterer exercising its rights to terminate this Agreement under
     Article 31 of this Agreement, then Lessor and Charterer shall as soon as
     reasonably practicable enter into a new accounts agreement in form and
     substance substantially similar to the Accounts Agreement. The obligations
     of Charterer under the said Accounts Agreement (and any successor accounts
     agreement entered into pursuant to the preceding sentence) shall be deemed
     for purposes of the Joint Venturer Guarantees to be obligations of
     Charterer hereunder.
 
25.   REDELIVERY OF FPSO
 
     The FPSO shall at the expiration or termination or as provided in Article
     31.2 (b) of this Agreement (unless lost or a constructive total loss or
     under requisition or purchased by Charterer) be redelivered to Lessor at
     the Offshore Site (the "Redelivery"), as is - where is, in accordance with
     the following conditions. The FPSO shall be redelivered to Lessor properly
     documented and in class with no recommendations, fair wear and tear not
     affecting class excepted. Charterer shall have discharged substantially all
     free crude oil (other than tank bottoms) from the FPSO. Any expenses of
     degassing or demucking conducted within 12 months of Redelivery shall be
     borne by Charterer. The FPSO shall upon Redelivery have her class
     certificates valid. Charterer will render the FPSO available to Lessor at
     the time of Redelivery for survey, inspection, testing and inventory check
     at
 
                                       18
<PAGE>
     Lessor's expense. Charterer at its expense shall meet its Redelivery
     obligations and the charter period shall be extended for the period
     necessary to make any deficiencies good. During any such period the
     compensation payable under Article 9 before Redelivery shall not be so
     payable provided Charterer's obligations herein are met promptly and
     expeditiously. Prior to and during the Redelivery of the FPSO, Charterer
     shall provide such reasonable assistance to Lessor as Lessor requests in
     order to effect taking Redelivery of the FPSO, including but not limited to
     temporary office facilities onshore and transportation from Charterer's
     shore base to the FPSO and vice versa for Lessor's personnel and supplies
     as is reasonable under the circumstances. On Redelivery, Lessor shall be
     free (i) to cut and either remove or abandon the anchor chains, the risers,
     buoyancy tanks and the control umbilicals (but so as to leave no hazard to
     shipping and to avoid damage to Charterer's wells, wellheads, pipelines,
     PLEMS or other equipment) and to remove the FPSO from the Offshore Site but
     without having any obligation to remove subsurface equipment or materials
     including piling or any other obligation to clear the Offshore Site and
     (ii) to remove any free crude oil not previously removed by Charterer at
     Charterer's expense.

31.1  Upon the occurrence of an Event of Default by Lessor or its affiliate and
     at any time thereafter so long as the same shall be continuing, Charterer
     may, at its option, upon ninety (90) days' notice thereof to Lessor,
     declare this Agreement to be in default; and, at any time thereafter, so
     long as Lessor shall not have remedied or have commenced and at all times
     thereafter diligently acted to remedy all outstanding Events of Default,
     Charterer (a) may terminate this Agreement, compensation as specified in
     Article 9.1 shall cease as of the date of termination and Charterer shall
     redeliver the FPSO to Lessor as if the FPSO were being redelivered pursuant
     to Article 25 hereof, or (b) accelerate its right to exercise the Purchase
     Option at a price to be determined by reference to Appendix C (offsetting
     any damages which have been established at the time of such purchase
     against the purchase price of the FPSO) and terminate compensation under
     Article 9.1. Lessor shall be liable for any and all damages to Charterer
     resulting from termination of this Agreement and for all legal fees and any
     other costs and expenses whatsoever incurred by Charterer by reason of the
     occurrence of any Event of Default or by reason of the exercise by
     Charterer of any remedy hereunder, including, without limitation, any costs
     and expenses incurred by Charterer in connection with Redelivery of the
     FPSO. Notwithstanding the remedies available to Charterer under this
     Article 31, the provisions of Article 18.9 shall apply so as to limit the
     damages of Charterer and any guarantors of Charterer's obligations
     hereunder, PROVIDED that if Lessor shall breach its obligation other than
     for reasons wholly outside its control to sell the FPSO to Charterer if
     Charterer exercises its Purchase Option under sub-clause (b) above, Lessor
     shall be liable to such guarantors for direct damages to the guarantors or
     any of their affiliates which are parties to the Gas Sales Agreement
     arising under Articles XV or XVIII of the Gas Sales Agreement. To the
     extent that such guarantors (and such affiliates) claim direct damages
     under the Gas Sales Agreement as provided in the preceding sentence, such
     guarantors and affiliates must use their reasonable efforts to mitigate
     their damages. Charterer must use reasonable efforts to mitigate its
     damages.

31.2  Upon the occurrence of an Event of Default by Charterer or its affiliate
     (provided that such Event of Default did not arise out of or result from
     actions, or omissions to act, of Operator under the Operating Agreement)
     and at any time thereafter so long as the same shall be continuing, Lessor
     may, at its option, upon ninety (90) (or, in the case of an Event of
     Default based on a failure to pay money when due (including a failure by
     reason of Force Majeure), thirty (30)) days' notice thereof to Charterer,
     declare this Agreement to be in default; and, at any time thereafter, so
     long as Charterer shall not have remedied or (except as to an Event of
     Default based on a failure to pay money when due) have commenced and at all
     times thereafter diligently acted to remedy all outstanding Events of
     Default Lessor may do, and Charterer shall comply with, one or more of the
     following, as Lessor in its sole discretion shall so elect, to the extent
     permitted by, and subject to compliance with any mandatory requirements of
     applicable law then in effect. Lessor must use reasonable efforts to
     mitigate its damages and shall apply any amounts received from the sale or
     re-charter (for a period equal to the remainder of the term of this
     Agreement) of the FPSO (after deducting Lessor's direct out-of-pocket
     expenses of making the FPSO ready for sale or re-charter) to reduce the
     amount of any charter hire and other amounts payable by Charterer to Lessor
     pursuant to the last paragraph of this Article 31.2. To the extent that
     Charterer fails to maintain in force any insurance coverage described in
     Article 17.3 and is not diligently acting to replace such coverage, Lessor
     shall be entitled to obtain such insurance for the account of Charterer.
 
     a)  Lessor may terminate this Agreement.
 
     b)  Upon written demand, Lessor may cause Charterer to, and Charterer
        hereby agrees that it will, redeliver the FPSO to Lessor within a
        reasonable period of time not to exceed 45 days and in the same manner
        and in the same condition as if the FPSO were being redelivered pursuant
        to Article 25 hereof; or Lessor or its agent, at Lessor's option, may,
        but shall be under no obligation to, retake the FPSO irrespective of
        whether Charterer or any other person may be in possession of the FPSO,
        upon 24 hours prior notice but without prior demand and without legal
        process, and for that purpose Lessor or its agent may take possession
        thereof.
 
     c)  Lessor or its agent may sell the FPSO at public or private sale, with
        notice to Charterer, or otherwise may dispose of, hold, use, operate,
        charter (whether for a period greater or less than the balance of what
        would have been the charter period for the FPSO in the absence of the
        termination of Charterer's rights to the FPSO) to others or keep idle,
        all on such terms and conditions and at such place or places as Lessor
        may determine.
 
     In addition, Charterer shall be liable for and shall pay to Lessor within
     thirty days after Lessor takes redelivery or possession of the FPSO a lump
     sum equal to any and all additional Hire payable during the Initial Term
     and for all legal fees and any other costs and expenses whatsoever incurred
     by Lessor by reason of the occurrence of any Event of Default or by reason
     of the exercise by Lessor of any remedy hereunder, including, without
     limitation, any costs and expenses incurred by Lessor in connection with
     the Redelivery or retaking of the FPSO.
 
31.3  Each party's remedies referred to in this Article 31 are intended to be
     the exclusive remedies of such party under this Agreement; PROVIDED,
     HOWEVER, that either party may enforce performance of these remedies by all
     legal or equitable means.
 
31.4  No express or implied waiver by either party of any Event of Default shall
     be in any way, or be construed to be, a waiver of any further or subsequent
     Event of Default.
 
32.   MISCELLANEOUS
 
32.1  a)  All terms and conditions of this Agreement shall be binding upon and
          shall enure to the benefit of the parties hereto and their respective
          successors and permitted assigns. Any purported assignment in
          contravention of this Article 32 shall be null and void.
 
                                       21
<PAGE>
     b)  Charterer shall be entitled to assign its rights, duties and
        obligations hereunder to an affiliate without the consent of Lessor
        PROVIDED that Lessor receives simultaneously with such assignment
        guarantees from the Joint Venturers in respect of such assignee's
        obligations in the terms set out in Article 5 hereof.
 
     c)  Any party having rights under this Agreement shall be entitled to
        pledge and/or assign its rights and, to the extent possible, and if
        requested, its duties and obligations under this Agreement by way of
        security to any lending institution providing financing for the
        transactions contemplated hereby or related to the development of the
        Tantawan Field or a collateral agent on their behalf provided that any
        such pledge or assignment does not release the assignor or any guarantor
        of the assignor's obligations hereunder, from any of their respective
        obligations to the Lessor or the Charterer as the case may be.
 
     d)  Charterer shall not subcharter the FPSO to any party including an
        affiliate without the prior written consent of Lessor such consent not
        to be unreasonably withheld.
 
     Save as specifically provided above, neither party hereto shall be entitled
     to assign any rights or obligations under this Agreement without the prior
     consent of the other party, not to be unreasonably withheld. Charterer
     shall maintain a written record that identifies Lessor as the person
     entitled to payments under this Agreement. In the event of an assignment by
     Lessor of any of its rights under this Agreement, such assignment will be
     reflected on the record maintained by Charterer.

32.2  This Agreement may be executed in one or more counterparts, all of which,
     taken together, shall constitute one original document.
 
32.3  Except as specifically provided herein to the contrary, each party hereto
     intends that this Agreement shall not benefit or create any right or cause
     of action to any person other than parties hereto or their permitted
     assignees.
 
32.4  The making, execution and delivery of this Agreement by the parties hereto
     have been induced by no representation, statements, warranties or
     agreements other than those herein expressed or set forth in the attached
     exhibits or schedules. This Agreement and such exhibits or schedules embody
     the entire understanding of the parties, and there are no further or other
     agreements or understandings, written or oral, in effect between the
     parties relating to the subject matter hereof, unless expressly referred to
     by reference herein.
 
32.5  This Agreement may be amended or modified and any condition herein
     specified may be waived by mutual consent of the parties by a written
     instrument executed on behalf of the parties.
 
32.6  The captions contained in this Agreement are for convenience of reference
     only and do not form a part of this Agreement and shall not affect the
     interpretation hereof.
 
32.7  If any portion of this Agreement shall be deemed by an arbitration
     tribunal or a court of competent jurisdiction to be unenforceable, the
     remaining portions shall be valid and enforceable only if, after excluding
     the portion deemed to be unenforceable, the remaining terms hereof shall
     provide for the consummation of the transactions contemplated herein in
     substantially the same manner as originally set forth at the date this
     Agreement was executed.
 
32.8  Each of the parties hereto intends this Agreement will be treated as a
     lease of the FPSO from Lessor to Charterer. Neither Charterer, Lessor, nor
     any of their respective affiliates will take any action nor file any
     document with any governmental authority including, without limitation, any
     tax return, which is inconsistent with such characterization of this
     Agreement as a lease.
 
      IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
in duplicate as of the 9th day of February, 1996.

                                BAREBOAT CHARTER
 
    This Bareboat Charter (this "Agreement"), made and entered into as of August
24, 1998, by and among Watertight Shipping B.V., a company organized under the
laws of The Netherlands ("Lessor"), and Thaipo Limited, a company organized
under the laws of the Kingdom of Thailand ("Thaipo"), Thai Romo Limited, a
company organized under the laws of the Kingdom of Thailand ("Thai Romo"),
Palang Sophon Limited, a company organized under the laws of the Kingdom of
Thailand ("Palang"), and B8/32 Partners Limited, a company organized under the
laws of the Kingdom of Thailand ("B8/32" and, together with Thaipo, Thai Romo
and Palang, the "Charterer").
 
                              W I T N E S S E T H
 
      WHEREAS, the Petroleum Concession Agreement No. 1/2q534/36, dated August
1, 1991, covering block B8/32 offshore Thailand was awarded by the Ministry of
Industry to Maersk Oil (Thailand) Ltd., Thaipo and Thai Romo, and Supplementary
Petroleum Concession No. 1 to Petroleum Concession No. 1/2534/36, dated March 6,
1992, permitted The Sophonpanich Co., Ltd., to enter into Petroleum Concession
No. 1/2534/36 (collectively, the "Concession Agreement");
 
      WHEREAS Thaipo, Thai Romo, Palang (formerly known as Sophon Thai Gulf
Limited which was successor in interest to The Sophonpanich Co. Ltd.) and B8/32
(formerly known as Maersk Oil (Thailand) Ltd.) are currently the concessionaires
under the Concession Agreement in that portion of the concession known as the
Benchamas Field;
 
      WHEREAS, Charterer desires to charter from Lessor on a bareboat basis a
Floating Storage and Offloading System known as the "Benchamas Explorer" (the
"FSO"), for use in the Benchamas Field, Thailand;
 
      NOW, THEREFORE, in consideration of the mutual covenants herein contained,
Lessor and Charterer agree as follows:
 
1.    TRANSPORTATION, INSTALLATION AND COMMISSIONING OF THE FSO.
 
     Lessor shall be responsible for delivery (the "Delivery") of the FSO to
     Charterer in international waters in the vicinity of Thailand (the
     "Delivery Site") as evidenced by a certificate of delivery issued by Lessor
     and countersigned by Charterer. Prior to Delivery, Lessor shall be fully
     responsible for and assume all risks with respect to the FSO. Charterer has
     hired an operator ("Operator") pursuant to an Operating Agreement (the
     "Operating Agreement") to operate the FSO commencing with Delivery.
     Operator shall be responsible for completing all work to be performed in
     respect of the FSO from Delivery until Field Acceptance, as herein defined,
     has occurred, including completing all construction work, transporting the
     FSO from the Delivery Site to the site in the Benchamas Field designated by
     Charterer (the "Offshore Site"), hooking-up the FSO on its anchoring system
     and completing all Performance Tests, as herein defined. Operator shall
     also be responsible for commissioning the FSO.
 
2.    FSO TO BE CHARTERED.
 
     Charterer hereby agrees to bareboat charter the FSO as described in
     APPENDIX A and its inventory from Lessor, for the period and upon the terms
     and conditions stated herein. Lessor represents, undertakes and warrants
     that at the time of Delivery the FSO shall comply with the requirements of
     the Technical Specifications set forth in APPENDIX A hereto (the "Technical
     Specifications") and shall be properly documented and classed as ABS A1
     Floating Storage and Offloading System, with no recommendations affecting
     class and as per the particulars of APPENDIX A. At the time of Delivery,
     the FSO shall be seaworthy and in every respect ready in hull, machinery
     and equipment for service hereunder.
 
                                       1
<PAGE>
3.    SERVICE.
 
     Charterer shall have the full use of the FSO at the Offshore Site and,
     subject to Lessor's approval, not to be unreasonably withheld or delayed,
     at any other place in the world where its operation is not prohibited by
     applicable law and/or regulations excluding, however, the United States of
     America and its territories. Charterer may subcontract to identified
     subcontractors certain of its obligations hereunder, including, but not
     limited to, those relating to the operation, maintenance and repair of the
     FSO. However, such subcontracts shall not relieve Charterer of such
     obligations, except to the extent that such obligations are subcontracted
     to a party acceptable to Lessor.
 
4.    DURATION OF CHARTER.
 
4.1.   The term (the "Initial Term") of this Agreement shall commence upon
     Delivery. The Initial Term shall end upon a date ten (10) years after the
     Hire Commencement Date (as defined in Article 9.1.).
 
4.2.   Neither Field Acceptance (as defined in the Operating Agreement) nor
     Final Acceptance (as defined in the Operating Agreement) by Charterer shall
     be construed as a waiver or discharge of any of the representations,
     warranties or undertakings of Lessor in or with respect to this Agreement
     or the FSO.
 
4.3.   Upon the expiration of the Initial Term, (a) Charterer shall have the
     option to terminate this Agreement, extend this Agreement on an annual
     basis at hire to be agreed upon by Lessor and Charterer, or purchase the
     FSO pursuant to Article 23. and (b) the Performance Guaranty shall be
     promptly returned to the issuer thereof. If Charterer is considering
     extending this Agreement, it shall give revocable notice of its desire to
     extend this Agreement at least 360 days prior to the expiration of the
     Initial Term. Upon the giving of such notice, Charterer and Lessor shall
     negotiate in good faith in an effort to reach agreement prior to 180 days
     prior to the end of the Initial Term on a Total Bareboat Rate for the term
     for which Charterer desires to extend this Agreement. In addition,
     Charterer shall have the option to purchase the FSO pursuant to Article 23.
     by irrevocable notice to Lessor at least 180 days prior to the end of the
     Initial Term. If no agreement on a Total Bareboat Rate for an extended term
     is timely reached and if no notice of an election to purchase the FSO is
     timely given, Charterer shall be deemed to have exercised its option to
     terminate this Agreement as of the end of the Initial Term.
 
5.    [INTENTIONALLY OMITTED].
 
6.    REPRESENTATIONS AND WARRANTIES.
 
6.1.   Lessor represents and warrants to Charterer that:
 
     (a) Lessor is a corporation duly organized and in good standing under the
        laws of The Netherlands; has all requisite corporate power and all
        material governmental licenses, authorizations, consents and approvals
        necessary to own its assets and carry on its business as now being or as
        proposed to be conducted; and is qualified to do business and is in good
        standing in all jurisdictions in which the nature of the business
        conducted by it makes such qualification necessary and where failure so
        to qualify could be reasonably expected to have a material adverse
        effect on its business.
 
     (b) Lessor has all necessary corporate power and authority to execute,
        deliver and perform its obligations under this Agreement; the execution,
        delivery and performance by Lessor of this Agreement have been duly
        authorized by all necessary corporate action on its part; and this
        Agreement has been duly and validly executed and delivered by Lessor and
        constitutes its legal, valid and binding obligation, enforceable against
        Lessor in accordance with its terms except to the extent such
        enforceability may be limited by (i) bankruptcy, insolvency,
        reorganization, moratorium or similar laws of general applicability
        affecting the enforcement of creditor's

        rights and (ii) the application of general principles of equity
        (regardless of whether such enforceability is considered in a proceeding
        in equity or at law).
 
     (c) The execution and delivery of this Agreement and the consummation of
        the transactions herein contemplated will not conflict with or result in
        a breach of the articles of association of Lessor or any applicable law
        or regulation or any material agreement or instrument to which Lessor is
        a party or by which it is bound or to which it is subject or constitute
        a default under any such material agreement or instrument.
 
     (d) All authorizations, approvals and consents of, and filings or
        registrations with, any governmental or regulatory authority or agency,
        as are at the date of Delivery necessary for the execution, delivery or
        performance by Lessor of this Agreement and for the legality, validity,
        or enforceability hereof, will have been obtained at such date and
        thereafter will be maintained until the expiration or termination of
        this Agreement.
 
     (e) Lessor is a "tax resident" as such term is defined in the
        Netherlands-Thailand tax treaty. Lessor covenants that neither Lessor
        nor any agent acting on its behalf in connection with the performance of
        Lessor's obligations under this Agreement has, or during the term of the
        Agreement will have, a permanent establishment in Thailand.
 
6.2.   Charterer represents and warrants to Lessor that:
 
     (a) Each of the companies comprising Charterer is duly organized and in
        good standing under the laws of the Kingdom of Thailand; has all
        requisite power and all material governmental licenses, authorizations,
        consents and approvals necessary to own its assets and carry on its
        business as now being or as proposed to be conducted; and is qualified
        to do business and is in good standing in all jurisdictions in which the
        nature of the business conducted by it makes such qualification
        necessary and where failure so to qualify could be reasonably expected
        to have a material adverse effect on its business.
 
     (b) Each of the companies comprising Charterer has all necessary power and
        authority to execute, deliver and perform its obligations under this
        Agreement; the execution, delivery and performance by each of the
        companies comprising Charterer of this Agreement have been duly
        authorized by all necessary action on its part; and this Agreement has
        been duly and validly executed and delivered by each of the companies
        comprising Charterer and constitutes its legal, valid and binding
        obligation, enforceable against each of the companies comprising
        Charterer in accordance with its terms except to the extent such
        enforceability may be limited by (i) bankruptcy, insolvency,
        reorganization, moratorium or similar laws of general applicability
        affecting the enforcement of creditor's rights and (ii) the application
        of general principles of equity (regardless of whether such
        enforceability is considered in a proceeding in equity or at law).
 
     (c) The execution and delivery of this Agreement and the consummation of
        the transactions herein contemplated will not conflict with or result in
        a breach of the organizational documents of each of the companies
        comprising Charterer or any applicable law or regulation or any material
        agreement or instrument to which any of the companies comprising
        Charterer is a party or by which it is bound or to which it is subject
        or constitute a default under any such material agreement or instrument.
 
     (d) All authorizations, approvals and consents of, and filings or
        registrations with, any governmental or regulatory authority or agency,
        as are at the date of Delivery necessary for the execution, delivery or
        performance by Charterer of this Agreement and for the legality,
        validity, or enforceability hereof, will have been obtained at such date
        and thereafter will be maintained until the expiration or termination of
        this Agreement.

6.3.   OTHER THAN AS SPECIFICALLY STATED IN THIS AGREEMENT NO PARTY SHALL BE
     DEEMED TO HAVE MADE ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR
     IMPLIED, INCLUDING, WITHOUT LIMITATION, AS TO THE TITLE, SEAWORTHINESS,
     MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE OR USE OF THE FSO OR
     ANY PART THEREOF.
 
7.    MAINTENANCE AND OPERATION.
 
7.1.   Lessor agrees that the FSO shall, from the date of Delivery and until
     termination of this Agreement in accordance with its terms, be in the full
     possession and at the absolute disposal for all purposes of Charterer and
     under Charterer's complete control in every respect. Subject to Lessor's
     obligations pursuant to Article 7.3. to cause the FSO to meet and maintain
     requirements of the American Bureau of Shipping ("ABS"), Charterer shall
     maintain the FSO in a good state of repair. In addition, Charterer shall
     maintain the FSO in efficient operating condition and in accordance with
     good commercial maintenance practice, and shall keep the FSO (subject to
     Article 7.3.) with valid, unexpired classification of the class as
     indicated in Article 2., free of recommendations and notations affecting
     class. Charterer shall furnish Lessor with one duplicate original or
     certified true copy of all class and flag certificates issued or notated
     during the duration of the charter upon their issuance or notation. Lessor
     shall keep all Thai, Panamanian (Panama being hereinafter referred to as
     the "Country of Registry") and other required certificates valid,
     up-to-date and in full force at all times. Charterer shall maintain the
     following maintenance reports, records, surveys and documents: Planned
     Maintenance System, Continuous Survey of Machinery and such other reports,
     records, surveys and documents as Lessor shall reasonably specify in
     writing. Charterer shall provide copies of such documents to Lessor upon
     Lessor's request. Lessor shall provide Charterer and Operator with all
     authorizations which Charterer may reasonably require in order to
     accomplish the actions required or permitted to Charterer under this
     Article 7.
 
7.2.   Charterer shall take immediate steps to have all necessary repairs done
     within a reasonable time.
 
7.3.   Provided that the FSO is located at the Offshore Site, in the event of
     any improvement, structural changes or new equipment becoming necessary for
     the continued operation of the FSO by reason of new class requirements or
     compulsory legislation or in order to maintain the FSO in compliance with
     the Technical Specifications, then Lessor shall carry out such work at its
     expense.
 
7.4.   Charterer shall establish and maintain financial security of
     responsibility in respect of oil or other pollution damage as required by
     any government or other division or authority thereof, to enable the FSO,
     without penalty or charge, lawfully to enter and remain at the Offshore
     Site in performance of this Agreement or in the case of removal of the FSO
     to another site as may be permitted by the terms hereof, at such other
     site. Charterer shall make and maintain all arrangements by bond or
     otherwise as may be necessary to satisfy such requirements at Charterer's
     sole expense.
 
7.5.   Charterer shall at its own expense and by its own procurement, except as
     stated to the contrary elsewhere, man, victual, operate, supply, fuel and
     repair the FSO whenever required during the duration of this Agreement and
     shall pay all charges and expenses of every kind and nature whatsoever
     incidental to its use and operation of the FSO under this Agreement. The
     master of the FSO (the "Master"), officers, crew and production personnel
     of the FSO shall be the servants of Operator for all purposes whatsoever.
 
7.6.   Charterer shall comply with the regulations of the Country of Registry
     and, to the extent applicable, the Kingdom of Thailand or any other
     jurisdiction within which the FSO is operating. Charterer will cause the
     FSO to comply at all times with all applicable laws, treaties and
     conventions and with all rules and regulations issued thereunder and to
     have on board, when required thereby, valid certificates showing compliance
     therewith.
 
                                       4
<PAGE>
7.7.   During the duration of this Agreement the FSO shall retain her present
     name and shall remain under and fly the flag of the Country of Registry,
     provided, however, that Charterer shall have the right to paint the FSO in
     its own colors, install and display its funnel insignia and fly its own
     house flag. Any change in such painting or change in such funnel insignia
     shall be for Charterer's account.
 
7.8.   (a)  Subject to Article 7.4. and Lessor's approval, which shall not be
     unreasonably withheld or delayed, Charterer shall have the right to add
     additional equipment, modify existing equipment or connect additional
     production facilities. Any such additions or modifications, including the
     installation thereof, shall be at the sole risk and expense of Charterer.
     Such additions, modifications and connections so installed shall, without
     necessity of further act, become part of the FSO and the property of
     Lessor; PROVIDED, HOWEVER, that so long as no Event of Default caused by
     Charterer (as defined in Article 30.) shall have occurred and be
     continuing, any such additions, modifications and connections not installed
     as replacements for property included on board the FSO on the date of Field
     Acceptance may be removed (so long as such removal can be accomplished
     without damage to the FSO) by Charterer, at its own expense and risk, at
     any time during, or at the expiration of, the Initial Term or any extension
     term upon reasonable prior notice, whereupon such equipment shall, without
     necessity of further act, become the property of Charterer.
 
     (b)  Charterer may, in the ordinary course of maintenance, repair or
     overhaul of the FSO, remove any item of property constituting a part of the
     FSO; PROVIDED, HOWEVER, that such item is replaced as promptly as possible
     by an item of property which is free and clear of all liens, encumbrances
     and rights of others and is in as good operating condition, is as seaworthy
     and has a value and utility at least equal to the item of property being
     replaced. Any item of property removed from the FSO as provided in the
     preceding sentence shall remain the property of Lessor until replaced in
     accordance with the terms of such sentence, but shall then, without further
     act, become the property of Charterer. Any such replacement item of
     property shall, without further act, become the property of Lessor and be
     deemed part of the FSO as defined herein for all purposes hereof.
 
     (c)  In the event that the FSO is relocated from the Offshore Site pursuant
     to Article 3. (but not as a result of any failure of the FSO to perform in
     accordance with the Technical Specifications at the Offshore Site or as a
     result of any required maintenance), Charterer shall be responsible for all
     costs of removal and installation and any design changes or equipment
     necessary for the FSO to perform in accordance with the Technical
     Specifications at its relocated site.
 
7.9.   Charterer shall have the use of all items of inventory, equipment and
     spares being part of or on board the FSO on the date of Delivery, which
     Lessor undertakes to provide at its expense. Such inventory will be
     specified pursuant to Article 14. At Redelivery, Charterer shall replace
     all items of inventory, equipment and spares so that the inventory at
     Redelivery equals the items of inventory, equipment and spares on board the
     FSO on the date of Delivery, or shall pay the Lessor a mutually agreeable
     price for any unreplaced items of inventory.
 
8.    INSPECTION.
 
8.1.   Lessor shall have the right at any reasonable time to inspect or survey
     the FSO itself or to instruct a duly authorized third-party surveyor to
     carry out such survey on its behalf to ascertain the condition of the FSO,
     and to satisfy itself that the FSO is being properly repaired, maintained
     and operated. Such inspections and surveys shall be at Lessor's risk and
     for Lessor's account. Charterer shall provide, free of charge to Lessor,
     upon reasonable request by Lessor, transportation from the shore base to
     the FSO and vice versa on its regular flights and, to the extent available,
     accommodations, catering and communication on board for such inspectors or
     surveyors.
 
8.2.   Charterer shall also permit Lessor to inspect the FSO's log books
     whenever requested and shall promptly furnish Lessor with full information
     regarding any material casualties or other accidents or damage to or caused
     by the FSO.
 
                                       5

9.    COMPENSATION.
 
9.1.   As full compensation for the performance by Lessor of its obligations
     under this Agreement, Charterer shall pay Lessor a hire ("Hire"). Hire
     shall accrue in accordance with this Article 9. commencing at 0001 hours
     local time at the Offshore Site on the date ("Hire Commencement Date") on
     later of (a) Field Acceptance, and (b) the earlier of (i) May 15, 1999 or
     (ii) the date on which crude oil is stored on the FSO.
 
     Except as otherwise provided herein, Hire shall continue to accrue until
     the date when the FSO is redelivered to Lessor under the terms of this
     Agreement. Hire for the ten (10) years after the Hire Commencement Date
     shall be paid at the rate of Twenty-Three Thousand Three Hundred and Thirty
     Dollars (US $23,330) per day, (the "Total Bareboat Rate"), except as
     otherwise specifically provided herein, no other compensation or
     reimbursement shall be due to Lessor for the performance of its obligations
     hereunder.
 
     Except as provided below, with respect to all Hire and all other amounts
     payable by Charterer hereunder, the maximum liability of Thaipo shall be
     limited to 31.66667% of such Hire and other amounts, the maximum liability
     of Thai Romo shall be limited to 31.66667% of such Hire and other amounts,
     the maximum liability of Palang shall be limited to 5.00000% of such Hire
     and other amounts, and the maximum liability of B8/32 shall be limited to
     31.666666% of such Hire and other amounts (each such percentage being
     referred to herein as the "Concessionaire Percentage"). Notwithstanding a
     member's Concessionaire Percentage, any member of Charterer shall have the
     right to pay Hire and other amounts on behalf of any other member of
     Charterer.
 
     The Concessionaire Percentages are intended to be the same as the
     percentage interest of each member of the Charterer under the Concession
     Agreement. If (i) any member of Charterer shall increase its percentage
     interest under the Concession Agreement or (ii) any member of Charterer
     shall assign any of its interest under the Concession Agreement to an
     entity that is not a member of Charterer, the Field Operator shall promptly
     notify Lessor of such change. Upon Lessor's receipt of notice from the
     Field Operator certifying an increase in percentage interest under the
     Concession Agreement or an assignment of an interest under the Concession
     Agreement, the Concessionaire Percentage for each member of Charterer shall
     be adjusted appropriately with respect to the maximum liability for Hire
     and other amounts that shall become payable on or after the date of such
     notice but such adjustment shall not affect the percentage liability of a
     member of Charterer for any Hire and all other amounts payable prior to the
     date of such notice. Notwithstanding the foregoing limitation of liability,
     the obligation of Charterer to pay Hire and all other amounts hereunder is
     absolute and unconditional to the extent set forth in this Agreement and
     Lessor shall have the remedies provided in Article 31.2. for any failure to
     pay Hire and all other amounts hereunder. If any member of Charterer shall
     assign any of its interest under the Concession Agreement to an entity that
     is not a member of Charterer, the assignee of such interest under the
     Concession Agreement shall at the time of such assignment be deemed to have
     a Concessionaire Percentage and to be a member of Charterer for all
     purposes of this Agreement as if such assignee had been an original
     signatory to this Agreement. If any member of Charterer assigns all of its
     interest under the Concession Agreement and provided that no Event of
     Default of Charterer (as defined in Article 30.) with respect to such
     assignor has occurred and is continuing, such member of Charterer shall be
     without further act released from any and all obligations under this
     Agreement which arise or accrue after the date of such assignment. Upon any
     change in Concession Percentages, Lessor, Charterer and each present and
     former member of Charterer agree to execute such additional documents and
     releases as may be requested to evidence the foregoing provisions
     including, without limitation, the assignee's agreement to be bound by the
     terms of this Agreement.
 
9.2.   Payment of Hire shall be made monthly in advance, without any discount,
     adjustment, set off or deduction, except as specifically set forth in this
     Article 9. or otherwise in this Agreement. Lessor
 
                                       6
<PAGE>
     shall provide invoices to Charterer covering each payment of Hire at least
     ten (10) days before due. Payment of Hire shall be made to such account or
     accounts with such first class bank as Lessor shall designate in writing.
     Lessor shall not change such designations without Charterer's consent,
     which consent shall not be unreasonably withheld.
 
     The first and second payment of Hire shall be paid in same day funds before
     the close of business at the place of payment on the fifth business day of
     the calendar month beginning after the Hire Commencement Date. Except as
     otherwise provided in this Agreement, subsequent payments of Hire shall be
     paid in same day funds at the place of payment on the fifth business day of
     each applicable calendar month during the Initial Term or an extended term
     ("Hire Payment Date"). Hire shall accrue on a daily basis; provided that
     Hire for any periods that constitute less than a calendar day shall be a
     pro rata portion of Hire for such calendar day. If a Hire Payment Date
     falls on a day which is not a banking day at the place of payment, payment
     shall instead be made on the next succeeding day that is a banking day at
     such place, without interest. Any Hire paid but not earned shall be
     refunded on the next Hire Payment Date (or as otherwise provided under this
     Agreement) to Charterer by Lessor.
 
9.3.   Upon request by Charterer, Lessor shall promptly pay to Charterer, or at
     the option of Charterer, at any time following an Event of Default by
     Lessor hereunder or a default under the Lessor Parent Company Guaranty,
     Charterer shall be entitled to deduct from the payments of Hire:
 
     (a) actual or reasonably estimated disbursements, if any, for Lessor's
        account;
 
     (b) any advances to Lessor's affiliates, contractors, subcontractors, or
        agents for expenses or disbursements for Lessor's account;
 
     (c) any previous overpayment of Hire, including payments made with respect
        to agreed periods of Downtime; PROVIDED, HOWEVER, that with respect to
        periods of Downtime that have not been agreed, Charterer shall not
        withhold Hire with respect thereto but that Hire paid with respect to
        such Downtime shall accrue interest at the rate of twelve percent (12%)
        per annum, compounded monthly, until agreed or settled through
        arbitration, whereupon Charterer may withhold such overpayment plus
        accrued interest through the date that Charterer recoups such Hire and
        interest;
 
     (d) any sums due in respect of Lessor's failure to meet Lessor's
        performance undertakings under this Agreement; and
 
     (e) any other sums or credits to which Charterer is entitled under this
        Agreement.
 
     If a deduction is made based on an estimate, the next Hire payment shall be
     adjusted, if necessary, to reflect any difference between such estimate and
     the actual amount of deduction that Charterer is able to verify. All
     deductions from Hire shall be verified by Charterer by production of
     vouchers or supporting documentation corresponding to the deductions within
     thirty (30) days after the applicable Hire Payment Date.
 
9.4.   Notwithstanding anything contained in this Article 9. to the contrary, if
     when a payment of Hire is due hereunder, Charterer reasonably expects to
     redeliver the FSO before the next Hire Payment Date, Hire shall be paid
     prorated to the estimated date of Redelivery (as defined), and from which
     estimate Charterer may deduct amounts due or reasonably expected to come
     due to Charterer from Lessor for (i) disbursements on Lessor's behalf or
     charges for Lessor's account pursuant to any provision hereof including
     Article 9.3. and (ii) bunkers on board at Redelivery. Promptly after
     Redelivery, any overpayment shall be refunded by Lessor, or any
     underpayment made good by Charterer.
 
9.5.   (a)  Should the FSO become an actual total loss, Hire shall cease at the
     time of its loss or, if such time is unknown, at the time from which the
     FSO was last heard. Should the FSO become a total
 
                                       7
<PAGE>
     loss of any other kind, if approved in writing by Charterer in accordance
     with sub-clause (d) below, including, without limitation, a constructive,
     compromised, agreed or arranged total loss (a "constructive total loss"),
     Hire shall cease at the time of the casualty resulting in such loss. Within
     ninety (90) days after Hire has ceased under this Article 9.5., all monies
     owing to Charterer under the provisions of this Agreement at the time Hire
     ceases under this Article 9.5. shall be paid to Charterer, and likewise
     Lessor shall be paid the net amount of all sums due from Charterer. If the
     FSO shall have been missing for at least forty-eight (48) hours when a
     payment of Hire would otherwise be due, such payment shall be postponed
     until the safety of the FSO is ascertained.
 
     (b)  Should the FSO become an actual total loss or a constructive total
     loss (i) for reasons other than negligence or willful misconduct of Lessor
     Group (as defined in Article 18.) and (ii) in circumstances where no Event
     of Default by Lessor or its affiliates, its Guarantor or the Operator (a
     "Lessor Party") has occurred and is continuing, this Agreement shall be
     deemed to be terminated as of the date on which the obligation to pay Hire
     ceases in accordance with Article 9.5.(a) without prejudice to (A) the
     payment obligations of Lessor and Charterer as described in Article 9.5.(a)
     and (B) any other provisions which would otherwise survive termination of
     this Agreement which, for the avoidance of doubt, does not include any
     obligation to rebuild the FSO or procure a new FSO.
 
     (c)  Should the FSO become an actual total loss or a constructive total
     loss either (i) for reasons where the gross negligence or willful
     misconduct of a member of Lessor Group is a contributing factor; PROVIDED,
     THAT, no member of Charterer Group is either grossly negligent or guilty of
     willful misconduct in connection with such loss, or (ii) in circumstances
     where an Event of Default by a Lessor Party has occurred and is continuing,
     then, irrespective of such total loss, Charterer shall have the remedies
     set out in Article 31. hereof.
 
     (d)  Lessor and its affiliates shall not be entitled to (i) claim under
     this Agreement or (ii) reach agreement with the insurers on the hull
     policies taken out by Lessor and its affiliates that, in either case, the
     FSO constitutes a total loss of any kind other than an actual total loss
     without the prior written approval of Charterer.
 
     (e)  An actual total loss or a constructive total loss will not constitute
     in and of itself an Event of Default and, provided that there are no unpaid
     claims which have been asserted by Charterer, the Performance Guaranty
     shall promptly be returned to the issuer thereof.
 
9.6.   In the event Charterer fails to make any payment (including without
     limitation any payment of Hire) due and owing to Lessor under this
     Agreement, Lessor shall so notify Charterer. If Charterer fails to pay
     amounts due and owing within five (5) business days after receipt of such
     notice, Charterer shall pay to Lessor, in addition to all other amounts
     then due and owing, a late fee at a rate equal to one-month LIBOR plus two
     percent (2%) on the amounts then due and owing for the period commencing on
     the date that such payment was due until paid without prejudice to any
     other remedies under this Agreement.
 
9.7.   All payments of Hire and other amounts due hereunder from one party to
     the other shall be made in United States Dollars by interbank transfer.
     Except as otherwise provided herein, all sums due by one party to the other
     shall be paid within 30 days of receipt of invoice.
 
10.   CHANGE IN LAW.
 
     The Total Bareboat Rate is based on the tax laws of Thailand and The
     Netherlands as of the date of this Agreement and Lessor's qualification as
     a Netherlands corporation entitled to protection under The
     Netherlands-Thailand tax treaty. In the event there are any changes in (i)
     tax laws of The Netherlands or their interpretation, or (ii) Lessor's
     qualification as a "tax resident" (as defined in the Netherlands-Thailand
     tax treaty) of The Netherlands which affect the cost to Lessor of
     chartering the FSO, such additional costs shall be for Lessor's account and
     Lessor shall hold
 
                                       8
<PAGE>
     Charterer harmless from the consequences thereof. In the event there are
     any changes in tax laws in Thailand (including The Netherlands-Thailand tax
     treaty) or their interpretation which affect the cost to Lessor of
     chartering the FSO which cannot be remedied by reasonable actions on
     Lessor's part, such additional costs shall be for Charterer's account and
     Hire shall be adjusted accordingly.
 
11.   TAXES.
 
     Subject to the provisions of Article 10. regarding changes in existing tax
     laws or the interpretation thereof, all taxes (including income and
     withholding taxes) which are due with respect to the payment of the Total
     Bareboat Rate pursuant to this Agreement shall be paid by Lessor or
     reimbursed to Charterer by Lessor, except that Thailand value added taxes

           master of this Vessel, nor any other person has the right,
           power or authority to create, incur or permit to be placed
           or imposed upon this Vessel, or its profits, any lien
           whatsoever, other than liens for master's and crew's wages
           or salvage.
 
     (c) Lessor warrants that it has not created and covenants that it will not
        create or permit to exist any Owner Encumbrance other than Permitted
        Encumbrances. Furthermore, Lessor shall indemnify, hold harmless and
        defend Charterer against any loss which Charterer may sustain by reason
        of, any Owner Encumbrances and/or Permitted Encumbrances (other than
        those set forth in Articles 13.1.(d)(i) and 13.1.(d)(ii) hereof).
 
     (d) "Permitted Encumbrances" shall mean (i) the rights of Charterer under
        this Agreement, (ii) the rights of Lessor under this Agreement, (iii)

                                       9
<PAGE>
        Charterer shall have received a Quiet Enjoyment Letter in the form
        attached hereto as APPENDIX E, and (v) liens arising in tort; and
        "Permitted Encumbrance" shall mean any of the foregoing.
 
     (e) "Owner Encumbrances" shall mean any liens, security interests or
        encumbrances resulting from voluntary or involuntary action by Lessor
        Group taken without the prior written approval of Charterer and not

13.2.  Charterer agrees that if a libel or a complaint in admiralty (for
     purposes of this Article 13.2. called a "claim") shall be filed against the
     FSO, or if the FSO shall be otherwise levied upon or taken into custody or
     detained or sequestered by virtue of proceedings in any court or tribunal
     or by any government or other authority because of any claim (excluding a
     claim arising by the action or inaction of Lessor, the Lessor Group or any
     of their affiliates), Charterer shall at its own expense within 15 days
     thereafter cause the FSO to be released and each such claim to be
     discharged (except to the extent that the same shall be contested by
     Charterer in good faith by appropriate proceedings and there exists at the
     time no Charterer Event of Default). Charterer agrees forthwith to notify
     Lessor by telegram or facsimile, confirmed by letter, of each such claim
     involving amounts in excess of US $500,000 and of the release and discharge
     of each such claim. Charterer agrees to advise in writing at least once in

     facilitating such compliance by the parties thereto.

        be required to sustain such rates in the event of adverse weather
        conditions as specified in the Terminal Regulations Manual, as defined
        in the Operating Agreement.
 
16.2.  Downtime shall occur notwithstanding the fact that maintenance or repairs
     are occurring, but excluding those resulting from Charterer's (but not
     Operator's) gross negligence or willful misconduct. Downtime shall not
     occur during the period that Charterer is adding or modifying equipment or
     connecting additional facilities pursuant to Article 7.8.(a) hereof.
 
16.3.  Downtime shall be deemed not to occur during an event which is a Force
     Majeure event hereunder.
 
16.4.  A Downtime Damages Period shall mean any calendar day, or a portion
     thereof beginning after Field Acceptance in which Downtime occurs. During
     any Downtime Damages Period resulting from the Downtime under Articles
     16.1.(a) and (b) above, Charterer shall not be obligated to pay Lessor the
     Total Bareboat Rate in respect of any Downtime which occurs. Downtime under
     Articles 16.1.(a) and (b) shall be calculated on an hourly basis with any

     Article 16.1.(c) above shall mean any calendar day or a portion thereof
     during which Downtime under Article 16.1.(c) has caused an offtake tanker
     to incur demurrage. As a result of a Downtime Damages Period under Article
     16.1.(c), Charterer shall be entitled to deduct any demurrage incurred
     during such Downtime Damages Period up to an amount not to exceed US
     $30,880 per day from the Total Bareboat Rate; PROVIDED, THAT, Charterer
     shall not deduct any demurrage if the amount of demurrage incurred during
     any single offloading does not exceed US $5,000. Charterer shall as soon as
     reasonably practicable notify Lessor of the occurrence of, and its estimate
     of the total amount of Downtime incurred. The Total Bareboat Rate, as
     invoiced on a monthly basis, shall be credited with any undisputed Downtime
     occurring during the prior month in accordance with Article 9.3.

     insurance which it has agreed to provide herein, or such insurance lapses

     under Article 30. by such party, and the other party, in addition to other
     remedies available to it under Article 31., shall have the immediate right,
     without notice or demand to the defaulting party, to obtain the insurance
     required pursuant to this Article which shall give rise to an immediate

     part of any of its obligations and responsibilities to the other party
     under this Agreement or to any third party, including its indemnification
     obligations under Article 18., nor does either party warrant to the other
     that such policies are adequate to indemnify it against any such risk, and
     the indemnifying party shall therefore be responsible for taking out, at
     its sole expense, such further or other policies as it considers necessary
     or prudent for its protection.

     retentions applicable to insurance taken out by such party.

     statute or convention with respect to claims by third parties (which shall
     exclude Charterer Group and Lessor Group) to the extent, and only to the
     extent, such losses, claims, demands, liabilities, damages, suits or

     damage to or injury, illness or death of third parties regardless of any
     right that may be afforded to any member of Charterer Group to claim
     limitation of liability under any applicable law, statute or convention
     with respect to claims by third parties (which shall exclude Charterer
     Group and Lessor Group) to the extent, and only to the extent, such losses,
     claims, demands, liabilities, damages, suits or actions arise out of
     Charterer Group's sole or concurrent active negligence; PROVIDED, FURTHER,
     that to the extent that any loss, claim, demand, liability, damage, suit or
     action brought by any third party arises in part out of Lessor Group's
     concurrent active negligence, Charterer shall indemnify, defend and save
     Lessor Group harmless from and against such loss, claim, demand, liability,
     damage, suit or action in the proportion to which the collective concurrent
     active negligence of all members of the Charterer Group bears to the total
     collective concurrent active negligence of all members of both the Lessor
     Group and the Charterer Group.
 
18.5.  (a)  From and after Field Acceptance, Charterer agrees to indemnify,
     defend and save Lessor Group harmless from and against any and all losses,
     claims, demands, liabilities, damages, costs, expenses, penalties and/or
     fines, suits or actions in rem or otherwise (including expenses and
     attorneys' fees) for loss or damage to Lessor Group arising out of seepage
     or pollution of crude oil and gas from reservoirs, pipelines, platforms and
     other property related thereto (excluding the FSO) owned or leased by
     Charterer Group while such property is in Charterer Group's custody and
     control, including cost of cleanup of same.
 
     (b)  With respect to seepage or pollution from the FSO, Charterer shall
     conduct cleanup operations and Lessor shall provide all reasonable
     assistance; ultimate financial responsibility for the cost of such cleanup
     will be borne by Lessor Group as provided in Article 18.6.(a). If Charterer
     causes crude oil or gas located on the FSO to be insured, Charterer shall
     cause Lessor Group to be named as co-insureds in such policy as their
     interests may appear.
 
18.6.  (a)  Notwithstanding Article 18.5., Lessor shall be solely responsible
     for and shall indemnify, defend and save Charterer Group harmless from and
     against any and all losses, claims, demands, liabilities, damages, costs,
     expenses, penalties and/or fines, suits or actions in rem or otherwise
     (including expenses and attorneys' fees) for loss or damage to Charterer
     Group arising from or caused by any seepage or pollution originating under
     or above the surface of the water from (i) spills of crude oil, gas, fuels,
     bunkers, slop tanks, lubricants, motor oils, pipe dope, paints, solvents,
     ballast, bilge, garbage and sewage in Lessor Group's possession or control
     (including the FSO) and (ii) any property or equipment (including the FSO)
     owned, leased or provided by the Lessor Group including costs of cleanup of
     same.

     (b)  Notwithstanding Article 18.5., Charterer shall be solely responsible
     for and shall indemnify, defend and save Lessor Group harmless from and
     against any and all losses, claims, demands, liabilities, damages, costs,
     expenses, penalties and/or fines, suits or actions in rem or otherwise
     (including expenses and attorneys' fees) for loss or damage to Lessor Group
     arising from or caused by any pollution originating under or above the
     surface of the water from (i) spills of fuels, bunkers, slop tanks,
     lubricants, motor oils, pipe dope, paints, solvents, ballast, bilge,
     garbage and sewage in Charterer Group's possession or control (other than
     FSO) and (ii) any property or equipment owned, leased or provided by the
     Charterer Group (other than the FSO) including costs of cleanup of same.
 
18.7.  Except as provided in Articles 18.3. and 18.4., all excuses from
     liability for one party and all indemnities given by one party to the other
     party or to the other party's Group pursuant to this Agreement shall apply
     regardless of the sole negligence or gross negligence or breach of duty or
     strict liability of the parties to be indemnified but shall not apply in
     the case of willful misconduct.
 
18.8.  As used herein, "affiliate" shall mean any company or legal entity which
     (i) controls either directly or indirectly a party hereto, or (ii) which is
     itself effectively controlled directly or indirectly by such party, or
     (iii) is directly or indirectly effectively controlled by a company or
     entity which directly or indirectly controls such party. "Control" means
     the right, whether by voting or otherwise, to appoint a director of the
     company concerned. "FSO," as used herein, shall include the FSO, the swivel
     and risers down to the outlet flange from the PLEM, and the export hoses up
     to and including the output flange on such hoses.
 
18.9.  In no event shall either party's Group be liable for any loss of
     production, loss of oil or gas, loss of revenue or profit, loss of
     commercial advantage, demurrage, or any consequential or indirect losses or
     damages suffered by the other party's Group as a result of any act or
     omission or negligence, unseaworthiness of the FSO or otherwise. This
     Article shall not be construed as a limitation upon the third party
     indemnification provisions of this Agreement.
 
18.10. The provisions of this Article 18. are intended to specifically allocate
       certain liabilities between the parties hereto in the events described in
       this Article 18 but shall not be interpreted to waive or excuse
       performance by any party of its representations, warranties and covenants
       set forth in this Agreement.
 
18.11. (a)  For the purposes of this Article 18.11., the term "Indemnitee" will
       refer to the person or persons indemnified or entitled (or claiming to be
       entitled) to be indemnified pursuant to the provisions of this Agreement;
       and the term "Indemnitor" will refer to the person having the obligation
       to indemnify pursuant to such provision.
 
     (b)  An Indemnitee will promptly give the Indemnitor notice of any matter
     that an Indemnitee has determined has given or could give rise to a right
     of indemnification under this Agreement, stating the amount of the loss,
     claim, demand, liability, damages, cost, expense, penalty and/or fine, suit
     or action in rem or otherwise (the "Claim") if known, and method of
     computation thereof, all with reasonable particularity, and stating with
     particularity the nature of such matter. Failure to provide such notice
     will not affect the right of the Indemnitee to indemnification except to
     the extent such failure will have resulted in liability to the Indemnitor
     that could have been avoided had such notice been provided promptly.
 
     (c)  The obligations and liabilities of an Indemnitor under this Agreement
     with respect to Claims of any third party that are subject to the
     indemnification provided for in this Article 18. ("Third Party Claims")
     will be governed by the following additional terms and conditions: if an
     Indemnitee receives notice of any Third Party Claim, the Indemnitee will
     give the Indemnitor notice of such Third Party Claim pursuant to clause (b)
     above, and the Indemnitor may, at its option, assume and control the
     defense of such Third Party Claim at the Indemnitor's expense and through
     counsel of
 
                                       16
<PAGE>
     the Indemnitor's choice that is reasonably acceptable to the Indemnitee. In
     the event the Indemnitor assumes the defense against any such Third Party
     Claim as provided above, the Indemnitee will have the right to participate
     at its own expense in the defense of such asserted liability, will
     cooperate with the Indemnitor in such defense and make available on a
     reasonable basis to the Indemnitor all witnesses, pertinent records,
     materials and information in its possession or under its control relating
     thereto as is reasonably required by the Indemnitor. In the event the
     Indemnitor does not elect to assume the defense against any such Third
     Party Claim, the Indemnitor will pay all reasonable costs and expenses of
     such defense as incurred and will cooperate with the Indemnitee (and be
     entitled to participate) in such defense and make available on a reasonable
     basis all such witnesses, records, materials and information in its
     possession or under its control relating thereto as is reasonably required
     by the Indemnitee. Except for the settlement of a Third Party Claim that
     involves the payment of money only and for which the Indemnitee is totally
     indemnified by the Indemnitor, no Third Party Claim may be settled without
     the prior written consent of the Indemnitee, which consent will not
     unreasonably be withheld or action with respect thereto unduly delayed. No
     Indemnitee shall be entitled to any indemnification under this Agreement
     from the Indemnitor for any Third Party Claim that it settles without the
     prior written consent of the Indemnitor in each instance.
 
19.   NON-WAIVER OF DEFAULTS.
 
19.1.  Any failure by either party at any time, or from time to time, to enforce
     or require the strict keeping and performance of any of the terms or
     conditions of this Agreement, or to exercise a right hereunder, shall not
     constitute a waiver of such terms or conditions.
 
20.   FORCE MAJEURE.
 
20.1.  Any loss or damage or delay in, or failure of performance of either party
     shall not constitute default hereunder or give rise to any claims for
     damages if and to the extent that such loss, damage, delay or failure is
     caused by "Force Majeure."
 
20.2.  In this Agreement "Force Majeure" shall denote any event the happening of
     which could not be prevented even though a person against whom it happened
     or threatened to happen were to take such appropriate care as might be
     expected of a Reasonable and Prudent Operator, as hereinafter defined.
     "Reasonable and Prudent Operator" when used to describe the standard of
     care to be exercised by a party in performing its obligations means the
     degree of diligence and prudence and foresight reasonably and ordinarily
     exercised by experienced operators engaged in the same line of business
     under the same or similar circumstances and conditions and when used to
     determine the action that would be required of a party means the action an
     experienced commercial operator engaged in the same line of business under
     the same or similar circumstances and conditions would take in the exercise
     of such due diligence, prudence and foresight. Notwithstanding Article
     20.1., Force Majeure shall not release either party from any obligation to
     give a notice or make any payment (including, in particular, any payment of
     Hire) under this Agreement except where the making of a payment is
     prevented by a Force Majeure event affecting the transfer of monies by the
     payor. Any payments which are so prevented from being made by reason of
     Force Majeure shall, upon the cessation of the Force Majeure event, be made
     as soon as practicable thereafter in addition to any other amounts which
     may then be payable by such party under this Agreement.
 
20.3.  Events which may, subject to Article 20.2., be considered Force Majeure
     events shall include but not be limited to acts of government, strikes,
     lock-outs, acts of public enemy, wars whether declared or undeclared,
     blockades, insurrection, riots, epidemics, landslides, lightning,
     earthquakes, fires, storms, floods, washouts, civil disturbances,
     explosions, breakage or accident to machinery or lines of pipe, freezing of
     wells or lines of pipe, partial or entire failure of wells, inability to
     obtain necessary materials or supplies due to changes in laws and
     regulations and material changes in the obligations of the concessionaire
     under the Concession Agreement, as herein defined, imposed
 
                                       17
<PAGE>
     unilaterally by the Government of Thailand and inability of PTT to accept
     delivery of gas delivered to PTT under the Gas Sales Agreement where such
     inability constitutes an event of Force Majeure under the Gas Sales
     Agreement which has been declared.
 
20.4.  A party claiming relief on account of Force Majeure shall:
 
     (a) as soon as practicable give notice to the other party of the happening
        said to constitute Force Majeure, such notice to include full
        information about the circumstances and a statement of the steps and
        time believed necessary to remedy the failure but neither party shall be
        obligated to settle or prevent any strike or other industrial action
        except on terms which, in its sole judgment, are acceptable to it; and
 
     (b) proceed as a Reasonable and Prudent Operator at its own expense to
        remedy the failure as rapidly as possible.
 
21.   LAW AND ARBITRATION.
 
21.1.  This Agreement shall be construed and governed in accordance with the
     maritime law of the United States of America and, to the extent such law is
     inapplicable, with the laws of the State of New York excluding any conflict
     of law rules. In connection with the interpretation of any exhibit hereto,
     the choice of law of this Agreement shall prevail.
 
21.2.  Any dispute arising under or in connection with this Agreement shall be
     settled by arbitration in New York City under the rules of the American
     Arbitration Association. The party requesting arbitration shall serve upon
     the other party a written demand for arbitration with the name and address
     of the arbitrator appointed by it, and such other party shall, within ten
     (10) days thereafter, appoint an arbitrator, and the two arbitrators so
     named, if they can agree, shall appoint a third. If the two arbitrators
     cannot agree, a third arbitrator shall be appointed by the American
     Arbitration Association. The decision or award of any two arbitrators shall
     be final and binding upon the parties. In no event shall any dispute or
     consolidated group of disputes be determined by more than three
     arbitrators. Should the party upon whom the demand for arbitration is
     served fail or refuse to appoint an arbitrator within ten (10) days, the
     single arbitrator shall have the right to decide alone, and his decision or
     award shall be final and binding upon the parties. The arbitrator(s) shall
     have the discretion to impose the cost of the arbitration proceedings,
     including reasonable attorney's fees upon the losing party, or divide it
     between the parties on any terms which may appear just; PROVIDED, HOWEVER,
     that in no event may the arbitrator(s) award any punitive, special or
     exemplary damages.
 
21.3.  Judgment upon the arbitration award rendered may be entered in any Court
     having either personal or in rem jurisdiction, or application may be made
     to such Court for a judicial acceptance of the award and an Order of
     Enforcement, as the case may be. In this regard, Lessor and Charterer
     hereby submit to the jurisdiction of the federal and state courts located
     in Houston, Harris County, Texas.

23.   PURCHASE OPTION.
 
23.1.  Provided that an Event of Default by Charterer under Article 30. of this
     Agreement is not existing, Charterer shall have the right to exercise an
     option (the "Purchase Option") to purchase the FSO (including its on-board
     spare parts) from the Lessor free from all encumbrances (except

     (b) at any time during the Initial Term at a price to be determined by
        reference to APPENDIX C-1, or
 
     (c) at any time during the Initial Term, if an Event of Default by Lessor
        has occurred under Article 30. of this Agreement and Charterer has
        elected, pursuant to Article 31.1.(b) hereof to exercise this Purchase
        Option for a price determined by reference to APPENDIX C-2; or
 
     (d) if, in the opinion of Charterer (and, if requested by Lessor, in the
        opinion of Charterer's outside counsel), such purchase is required by
        relevant governmental authorities pursuant to
 
                                       19
<PAGE>
        applicable laws, rules, regulations or agreements with such governmental
        authorities, for a price determined by reference to APPENDIX C-1.
 
23.2.  Lessor agrees that if Charterer exercises any option pursuant to this
     Article 23. to purchase the FSO, Lessor will on or before the scheduled
     closing of such purchase cause all liens with respect to the FSO (except
     liens caused by the Charterer Group) to be lifted.
 
23.3.  Except with respect to Article 23.1.(c), in the event that Charterer
     exercises its Purchase Option, such purchase price shall be reduced by any
     amounts due from Lessor under this Agreement which have been mutually
     agreed or determined pursuant to the terms of Article 21. at the time of
     such purchase.
 
23.4.  If Charterer is exercising its Purchase Option pursuant to Article
     23.1.(a), (b) or (c) above, Charterer shall provide notice of its intent to
     do so in accordance with the relevant provisions of this Agreement. If
     Charterer is exercising its Purchase Option pursuant to Article 23.1.(d)
     above, Charterer shall provide notice of its intent to do so at the
     earliest reasonable practicable opportunity.
 
23.5.  In the event the Purchase Option is exercised, unless agreed otherwise

               Panamanian registry of vessels within thirty (30) days of the
               date of delivery of the FSO to Charterer,
 
          (iv) Copies of class and trading certificates (where relevant to its

          (v) All government approvals necessary to transfer the FSO to
              Charterer and, if requested by Charterer, to delete the FSO from

              jurisdiction over Lessor's power to sell the FSO,
 
          (vi) Copies of all log books, classification certificates, manuals and
               other documents in the Lessor's possession or control arising out
               of or related in any way to the FSO's design, engineering,

         (vii) Physical possession of the FSO.
 
     (b) On delivery, Charterer shall pay the purchase price to Lessor or its
        designee by transfer to Lessor's account then designated for receipt of

        the issuer thereof.
 
     (c) Each party shall deliver to the other party such additional
        documentation or take such additional action as such other party may

                                       20
<PAGE>
        conflict with the provisions of this Agreement, provided that Lessor
        shall not be required to arrange or pay for a dry-docking or inspection
        of the FSO for purposes of said sale and purchase.
 
24.   GUARANTY.
 
24.1.  Lessor has delivered to Charterer a Guaranty and Indemnity Agreement
     ("Lessor Parent Company Guaranty") in the form of APPENDIX B-1 hereto,
     executed by its ultimate corporate parent, Omni Offshore Holdings, Limited,
     a company organized under the laws of Liberia, guaranteeing the performance
     by Lessor of its obligations hereunder.
 
24.2.  Upon Delivery, Lessor or its designee shall provide to Charterer, at
     Lessor's sole expense, an irrevocable and unconditional letter of credit in
     favor of Charterer in the amount of Five Million Dollars (US $5,000,000) to
     guarantee the due, proper and full performance by Lessor of its obligations
     under this Agreement (the "Performance Guaranty"). The Performance Guaranty
     shall be (i) executed on a form attached hereto as APPENDIX B-2 with such
     modifications as are acceptable to Charterer, (ii) issued by a bank
     acceptable to Charterer, and (iii) valid and available to Charterer until a
     date not less than ninety (90) days after the end of the Initial Term;
     PROVIDED, HOWEVER, that the term of the Performance Guaranty shall
     initially be for a period of one (1) year, but shall be continually renewed
     and extended, each renewal and extension to be for a period of one year if,
     as of ten (10) days prior to the expiration of the initial term of the
     Performance Guaranty, or any renewal or extension thereof, the term of the
     Performance Guaranty is less than ninety (90) days more than the Initial
     Term. In addition to any other rights Charterer may have to draw upon the
     Performance Guaranty, Charterer shall have the immediate right to draw upon
     the Performance Guaranty in full prior to its expiration if (i) Lessor has
     not timely renewed and extended the Performance Guaranty in accordance with
     the immediately preceding sentence or (ii) Lessor attempts to terminate the
     Performance Guaranty prior to ninety (90) days after the expiration of the
     Initial Term; PROVIDED, HOWEVER, that if Lessor subsequently delivers a new
     Performance Guaranty and there is no other existing Event of Default by
     Lessor, Charterer shall promptly pay to Lessor any amounts drawn by
     Charterer pursuant to this sentence. In the event that Lessor or its
     Guarantor or its or their subcontractors fail to comply with any of their
     obligations under this Agreement and Charterer, as a result, shall have the
     right at any time under this Agreement either to (i) be reimbursed or
     indemnified by Lessor or its Guarantor for any loss or expenditure incurred
     by Charterer or (2) receive any contractual damages (including liquidated
     damages) from Lessor, then Charterer shall have the right to draw on the
     Performance Guaranty on its first demand and thereafter from time to time
     in such amount as needed to satisfy such obligation of Lessor or its
     Guarantor to Charterer. In the event of a draw on the Performance Guaranty,
     other than a draw in connection with the termination of the Agreement,
     Lessor shall, within ten (10) Business Days from the date of such draw,
     restore the Performance Guaranty to Five Million Dollars (US $5,000,000).
     Any draw on the Performance Guaranty shall be effected by the member of the
     Charterer that is at the time such draw the field operator pursuant to the
     Concession Agreement (the "Field Operator").
 
25.   REDELIVERY OF FSO.
 
     The FSO shall at the expiration or termination or as provided in Article
     31.2.(b) of this Agreement (unless lost or a constructive total loss or
     under requisition or purchased by Charterer) be redelivered to Lessor at
     the Offshore Site (the "Redelivery"), as is - where is, in accordance with
     the following conditions. The FSO shall be redelivered to Lessor properly
     documented and in class with no recommendations, fair wear and tear not
     affecting class excepted. Charterer shall have discharged substantially all
     free crude oil (other than tank bottoms) from the FSO. Any expenses of
     degassing or demucking upon Redelivery shall be borne by Lessor. The FSO
     shall upon Redelivery have her class certificates valid. Charterer will
     render the FSO available to Lessor at the time of
 
                                       21
<PAGE>
     Redelivery for survey, inspection, testing and inventory check at Lessor's
     expense. Charterer at its expense shall meet its Redelivery obligations and
     the charter period shall be extended for the period necessary to make any
     deficiencies good. During any such period the compensation payable under
     Article 9. before Redelivery shall not be so payable provided Charterer's
     obligations herein are met promptly and expeditiously. Prior to and during
     the Redelivery of the FSO, Charterer shall provide such reasonable
     assistance to Lessor as Lessor requests in order to effect taking
     Redelivery of the FSO, including but not limited to temporary office
     facilities onshore and transportation from Charterer's shore base to the
     FSO and vice versa for Lessor's personnel and supplies as is reasonable
     under the circumstances. On Redelivery, Lessor shall be free (i) to cut and
     either remove or abandon the anchor chains, the risers, buoyancy tanks and
     the control umbilicals (but so as to leave no hazard to shipping and to
     avoid damage to Charterer's wells, wellheads, pipelines, PLEM or other
     equipment) and to remove the FSO from the Offshore Site but without having
     any obligation to remove subsurface equipment or materials including piling
     or any other obligation to clear the Offshore Site and (ii) to remove any
     free crude oil not previously removed by Charterer at Charterer's expense.
 
26.   REQUISITION.
 
26.1.  If the FSO is seized, expropriated, confiscated, nationalized or
     requisitioned by any authority (other than the government, or any
     department, commission or agency thereof, of the Country of Registry,
     whether a legally constituted governmental authority or otherwise), and
     such seizure, expropriation, confiscation, nationalization or requisition
     has continued for a period of at least 30 consecutive days, this Agreement,
     at the option of Charterer, may continue in force or may be terminated at
     any time during the period of seizure, expropriation, confiscation,
     nationalization or requisition, provided that in the event Charterer elects
     to terminate, notice shall be given to Lessor by Charterer and
     compensation, as specified in Article 9., shall cease as of the date
     occurring 30 days prior to the date of notice of termination and the FSO
     shall be deemed to have been Redelivered to Lessor by Charterer. If
     Charterer has previously paid any or all of such compensation in respect of
     such 30 day period, Lessor shall promptly refund such amount to Charterer.
 
26.2.  In the event the FSO is seized, expropriated, confiscated, nationalized
     or requisitioned (collectively, an "Expropriation") by the government, or
     any department, commission or agency thereof, of the Country of Registry,
     whether a legally constituted governmental authority or otherwise, this
     Agreement shall be deemed terminated and compensation, as specified in
     Article 9.1., shall cease as of the date of Expropriation and the FSO shall
     be deemed to have been redelivered to Lessor by Charterer; PROVIDED, THAT,
     the provisions of this Article 26.2. with respect to termination of this
     Agreement shall not become applicable until the earlier of (a) one (1)
     month after such Expropriation or (b) the date that Lessor and, if
     applicable, Charterer have agreed that the FSO cannot be released from such
     Expropriation.
 
26.3.  In the event any seizure, expropriation, confiscation, nationalization or
     requisition of the FSO occurs, Lessor shall use its best efforts to arrange
     the release of the FSO therefrom (including, without limitation, changing
     the Country of Registry of the FSO) and shall afford Charterer the
     opportunity to join in any such action.
 
27.   GENERAL AND PARTICULAR AVERAGE.
 
     General average if any shall be adjusted according to the York-Antwerp
     Rules 1994 or any subsequent modification thereof current at the time of
     the casualty.
 
28.   SALVAGE.
 
     All salvage and towage shall be for Lessor's benefit and the cost of
     repairing damage occasioned thereby shall be borne by Lessor.

<PAGE>
29.   AUDIT.
 
     Lessor shall maintain its records which pertain to Articles 9. and 11.
     hereof in accordance with generally accepted international accounting
     principles and will keep copies of all applicable documents, forms and

     records at any time upon request during regular business hours.
 
30.   DEFAULT.
 
     The following events by either party hereto or any guarantor ("Guarantor")
     under the Lessor Parent Company Guaranty shall constitute an Event of
     Default:
 
     (a) failure to observe any material covenant, condition or agreement to be
        performed or observed by said party hereunder or any Guarantor under the
        Lessor Parent Guaranty; or
 
     (b) any representation or warranty made herewith or pursuant hereto or
        pursuant to the Lessor Parent Company Guaranty shall prove to be
        incorrect at any time in any material respect; or
 
     (c) said party or Guarantor shall become insolvent or bankrupt or consent
        to the appointment of a trustee or receiver, or a trustee or receiver
        shall be appointed for said party or for a substantial part of its
        property without its consent and shall not be dismissed for a period of
        thirty (30) days, or bankruptcy, reorganization or insolvency
        proceedings shall be instituted by or against said party and, if
        instituted against said party, shall not be dismissed for a period of
        thirty (30) days, and at any time thereafter so long as the same shall
        be continuing; PROVIDED, THAT, in any such case, no other Guarantor has
        agreed within such thirty (30) day period to accept and fulfill the
        obligations of such insolvent, reorganizing or bankrupt party or
        Guarantor; or
 
     (d) A Force Majeure Event shall have occurred preventing payment by
        Charterer of amounts due hereunder and such failure to pay continues
        unremedied for a period of 60 consecutive days.
 
31.   REMEDIES.
 
31.1.  Upon the occurrence of an Event of Default of Lessor or its affiliate and
     at any time thereafter so long as the same shall be continuing, Charterer
     may, at its option, upon ninety (90) days' (or in the case of a failure to
     maintain or renew the full amount of the Performance Guaranty, two (2)
     Business Days') notice thereof to Lessor, declare this Agreement to be in
     default; and, at any time thereafter, so long as Lessor shall not have
     remedied or have commenced and at all times thereafter diligently acted to
     remedy all outstanding Events of Default, Charterer may:
 
     (a) terminate this Agreement, compensation as specified in Article 9.1.
        shall cease as of the date of termination and Charterer shall redeliver
        the FSO to Lessor as if the FSO were being redelivered pursuant to
        Article 25. hereof; or
 
     (b) exercise its right to exercise the Purchase Option at a price to be
        determined by reference to APPENDIX C-2 (offsetting any damages which
        have been established at the time of such purchase against the purchase
        price of the FSO to the extent provided below) and terminate
        compensation under Article 9.1.
 
     In either case, Charterer shall also have the additional right to draw upon
     the Performance Guaranty as provided in Article 24.2.
 
     If Charterer exercises its Purchase Option under sub-clause (b) above, it
     will not offset any damages against the price set forth in APPENDIX C-2
     except to the extent that (i) no additional drawings under the Performance
     Guaranty are available, and (ii) Charterer's damages exceed the difference
     between the amount set forth in APPENDIX C-1 minus the amount set forth in
     APPENDIX C-2 as of the date of purchase of the FSO; PROVIDED, HOWEVER, that
     the foregoing limitation on offset of
 
                                       23
<PAGE>
     damages shall not in any manner limit or diminish Charterer's claim for
     damages under this Agreement, the Performance Guaranty or the Lessor Parent
     Guaranty.
 
     In addition to all other remedies available at law or in contract (and
     otherwise permitted by this Agreement), Lessor shall be liable for any and
     all damages to Charterer resulting from termination of this Agreement and
     for all legal fees and any other costs and expenses whatsoever incurred by
     Charterer by reason of the occurrence of any Event of Default or by reason
     of the exercise by Charterer of any remedy hereunder, including, without
     limitation, any costs and expenses incurred by Charterer in connection with
     Redelivery of the FSO. Notwithstanding the remedies available to Charterer
     under this Article 31., the provisions of Article 18.9. shall apply so as
     to limit the damages of Charterer, PROVIDED that if Lessor shall breach its
     obligation other than for reasons wholly outside its control to sell the
     FSO to Charterer if Charterer exercises its Purchase Option under
     sub-clause (b) above, Lessor shall be liable to the Charterer for direct
     damages to Charterer arising from such breach. Charterer must use
     reasonable efforts to mitigate its damages.
 
31.2.  Upon the occurrence of an Event of Default of Charterer (provided that
     such Event of Default did not arise out of or result from actions, or
     omissions to act, of Operator under the Operating Agreement) and at any
     time thereafter so long as the same shall be continuing, Lessor may, at its
     option, upon ninety (90) days' notice (or, in the case of an Event of
     Default based on a failure to pay money when due (including a failure by
     reason of Force Majeure), thirty (30) days' notice) thereof to Charterer,
     declare this Agreement to be in default; and, at any time thereafter, so
     long as Charterer shall not have remedied or (except as to an Event of
     Default based on a failure to pay money when due) have commenced and at all
     times thereafter diligently acted to remedy all outstanding Events of
     Default, Lessor may do, and Charterer shall comply with, one or more of the
     following, as Lessor in its sole discretion shall so elect, to the extent
     permitted by, and subject to compliance with any mandatory requirements of
     applicable law then in effect:
 
     (a) Lessor may terminate this Agreement.
 
     (b) Upon written demand, Lessor may cause Charterer to, and Charterer
        hereby agrees that it will, redeliver the FSO to Lessor within a
        reasonable period of time not to exceed 45 days and in the same manner
        and in the same condition as if the FSO were being redelivered pursuant
        to Article 25. hereof; or Lessor or its agent, at Lessor's option, may,
        but shall be under no obligation to, retake the FSO irrespective of
        whether Charterer or any other person may be in possession of the FSO,
        upon 24 hours prior notice but without prior demand and without legal
        process, and for that purpose Lessor or its agent may take possession
        thereof.
 
     (c) Lessor or its agent may sell the FSO at public or private sale, with
        notice to Charterer, or otherwise may dispose of, hold, use, operate,
        charter (whether for a period greater or less than the balance of what
        would have been the charter period for the FSO in the absence of the
        termination of Charterer's rights to the FSO) to others or keep idle,
        all on such terms and conditions and at such place or places as Lessor
        may determine.
 
     Notwithstanding the foregoing, in the event of an Event of Default by
     Charterer under Article 30., the Event of Default of Charterer shall be
     deemed to be cured for all purposes if any member of Charterer which has
     not caused the Event of Default of Charterer pursuant to Article 30. shall
     increase its respective Concessionaire Percentage so that the
     Concessionaire Percentages of all members of Charterer which have not
     caused the Event of Default of Charterer pursuant to Article 30. shall
     total 100% and no amounts are due and owing by Charterer under this
     Agreement.
 
     In addition, Charterer shall be liable for and shall pay to Lessor within
     thirty days after Lessor takes redelivery or possession of the FSO a lump
     sum equal to the discounted present value (discounted at an annually
     compounded percentage rate of twelve percent (12%) per annum) of any and
     all remaining Hire payable during the Initial Term, as well as the actual
     amount of all legal fees and
 
                                       24
<PAGE>
     any other costs and expenses whatsoever incurred by Lessor by reason of the
     occurrence of any Event of Default of Charterer or by reason of the
     exercise by Lessor of any remedy hereunder, including, without limitation,
     any costs and expenses incurred by Lessor in connection with the Redelivery
     or retaking of the FSO. Lessor must use reasonable efforts to mitigate its
     damages and shall apply any amounts received from the sale or re-charter
     (for a period equal to the remainder of the term of this Agreement) of the
     FSO (after deducting Lessor's direct out-of-pocket expenses of making the
     FSO ready for sale or re-charter) to reduce the amount of any charter hire
     and other amounts payable by Charterer to Lessor pursuant to the last
     paragraph of this Article 31.2.
 
31.3.  Each party's remedies referred to in this Article 31. are intended to be
     the exclusive remedies of such party under this Agreement; PROVIDED,
     HOWEVER, that either party may enforce performance of these remedies by all
     legal or equitable means.
 
31.4.  No express or implied waiver by either party of any Event of Default
     shall be in any way, or be construed to be, a waiver of any further or
     subsequent Event of Default.
 
32.   MISCELLANEOUS.
 
32.1.  (a) All terms and conditions of this Agreement shall be binding upon and
           shall inure to the benefit of the parties hereto and their respective
           successors and permitted assigns. Any purported assignment in
           contravention of Article 9.1. or this Article 32. shall be null and
           void.
 
     (b) Charterer shall be entitled to assign its rights, duties and
        obligations hereunder to an affiliate without the consent of Lessor;
        PROVIDED, THAT, such assignment shall not relieve Charterer for any of
        its obligations under this Agreement.
 
     (c) Any member of Charterer shall be entitled to pledge and/or assign its
        rights under this Agreement by way of security to any lending
        institution providing financing for the transactions contemplated hereby
        or related to the development of the concession or a collateral agent on
        their behalf provided that any such pledge or assignment does not
        release the assignor of the assignor's obligations hereunder, from any
        of their respective obligations to the Lessor.
 
     (d) Charterer shall not subcharter the FSO to any party including an
        affiliate without the prior written consent of Lessor such consent not
        to be unreasonably withheld.
 
     Save as specifically provided above and in Articles 9.1. and 13.1.(d),
     neither party hereto shall be entitled to assign any rights or obligations
     under this Agreement without the prior consent of the other party, not to
     be unreasonably withheld. Charterer shall maintain a written record that
     identifies Lessor as the person entitled to payments under this Agreement.
     In the event of a permitted assignment by Lessor of any of its rights under
     this Agreement, such assignment will be reflected on the record maintained
     by Charterer.
 
32.2.  This Agreement may be executed in one or more counterparts, all of which,
     taken together, shall constitute one original document.
 
32.3.  Except as specifically provided herein to the contrary, each party hereto
     intends that this Agreement shall not benefit or create any right or cause
     of action to any person other than parties hereto or their permitted
     assignees.
 
32.4.  This Agreement may be amended or modified and any condition herein
     specified may be waived by mutual consent of the parties by a written
     instrument executed on behalf of the parties.
 
32.5.  The captions contained in this Agreement are for convenience of reference
     only and do not form a part of this Agreement and shall not affect the
     interpretation hereof.
 
32.6.  If any provision of this Agreement is held to be illegal, invalid or
     unenforceable under present or future law effective during the term hereof,
     such provision shall be fully severable. This Agreement
 
                                       25
<PAGE>
     shall be construed and enforced as if such illegal, invalid or
     unenforceable provision had never comprised a part hereof and the remaining
     portions hereof shall remain in full force and effect and shall not be
     effected by the illegal, invalid or unenforceable provision or by its
     severance herefrom. Furthermore, in lieu of such illegal, invalid or
     unenforceable provision there shall be added automatically as part of this
     Agreement a provision as similar in terms to such illegal, invalid or
     unenforceable provision as may be possible and be legal, valid and
     enforceable.
 
32.7.  Each of the parties hereto intends this Agreement will be treated as a
     lease of the FSO from Lessor to Charterer. Neither Charterer, Lessor, nor
     any of their respective affiliates will take any action nor file any
     document with any governmental authority including, without limitation, any
     tax return, which is inconsistent with such characterization of this
     Agreement as a lease.
 
32.8.  Termination of this Agreement, regardless of cause, shall not relieve
     either party of its respective obligations and limitations arising from or
     incident to this Agreement prior to its termination including, without
     limitation, each parties indemnification obligations hereunder.
 
                                       26

      IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
in duplicate as of the day, month and year just written above.
